1 Introduction<br />

1.1 Purpose of this Environmental <strong>Statement</strong><br />

1.1.1 This Environmental <strong>Statement</strong> (<strong>ES</strong>) reports the outcome of an Environmental Impact<br />

Assessment (EIA) of the proposed Carron Valley Wind Farm (hereafter referred to as the<br />

‘proposed wind farm’). It has been prepared to accompany an application <strong>for</strong> planning<br />

permission in full to Stirling Council to construct and operate a wind farm comprising fifteen<br />

turbines at Cairnoch Hill, immediately north of the Carron Valley Reservoir (approximate grid<br />

reference NS 6970 8550).<br />

1.1.2 The site of the proposed wind farm is located approximately 10 km north west of<br />

Cumbernauld and approximately 7 km north of Kilsyth. The southern boundary of the site is<br />

bounded by the B818 and Carron Valley Reservoir. Carron Valley <strong>for</strong>est is located to the<br />

south of the reservoir. The site location is shown on Figure 1.1.<br />

1.1.3 The site is owned by Scottish Ministers and managed by the Forestry Commission Scotland<br />

(FCS). The site is part of the Scottish Lowlands Forest District.<br />

1.1.4 The proposed wind farm will comprise 15 turbines, an anemometry mast, associated<br />

infrastructure and ancillary development including access tracks and a control building. The<br />

proposed layout of the wind farm and its main infrastructure components is shown on Figure<br />

1.2.<br />

1.1.5 The applicant is Carron Valley Wind Farm LLP, which is the legal entity set up <strong>for</strong> the sole<br />

purpose of developing the Carron Valley Wind Farm. Carron Valley Wind Farm LLP is wholly<br />

owned by <strong>Partnerships</strong> <strong>for</strong> <strong>Renewables</strong> Ltd (hereafter referred to as ‘PfR’), who act as, and<br />

will be referred to as, the developer <strong>for</strong> this project.<br />

1.1.6 The proposed wind farm must be the subject of an EIA, the rationale <strong>for</strong> which is provided in<br />

Chapter 2: The EIA and Scoping Process. Environmental effects of the proposed wind farm<br />

have been studied systematically through an iterative process and the results are presented<br />

within this <strong>ES</strong>. The <strong>ES</strong> in<strong>for</strong>ms readers of the nature of the development, predicted<br />

significant environmental effects and the measures proposed to protect and enhance the<br />

environment during construction, operation and decommissioning. The statutory requirement<br />

<strong>for</strong> EIA discussed further in Chapter 2: The EIA and Scoping Process.<br />

1.1.7 This Environmental <strong>Statement</strong> comprises four parts:<br />

• Non-Technical Summary (NTS) – summarises the findings of the EIA in an<br />

accessible way using non-technical language;<br />

• <strong>ES</strong> <strong>Vol</strong>ume 1: <strong>Written</strong> <strong>Statement</strong> - detailing how the EIA process has been applied to<br />

this scheme; describing the proposed development and how it has evolved and<br />

reporting the findings of the EIA on each of the environmental topics identified through<br />

the Scoping process;<br />

• <strong>ES</strong> <strong>Vol</strong>ume 2: Figures – the figures to accompany the text in <strong>Vol</strong>ume 1; and<br />

• <strong>ES</strong> <strong>Vol</strong>ume 3: Technical Appendices – technical material to support the text<br />

presented in <strong>Vol</strong>ume 1.<br />

Carron Valley Wind Farm<br />

1.1.8 <strong>Vol</strong>ume 1 of the <strong>ES</strong> is structured as follows:<br />

• Chapters 1 to 6 describe the background to the project, scoping process,<br />

methodology and outcome, EIA process and methodology, site selection and design,<br />

the project as proposed, the legislative and policy context, and climate change and<br />

atmospheric emissions respectively.<br />

• Chapters 7 - 15 detail the technical assessments of the predicted environmental<br />

effects of the development, the proposed or in-built mitigation measures to reduce any<br />

negative effects, ongoing consultation and monitoring.<br />

• Chapter 16 presents a summary of effects and a schedule of proposed mitigation and<br />

enhancement measures.<br />

1.1.9 A glossary of terms used in the <strong>ES</strong> is presented at the front of the document.<br />

1.1.10 Although not part of the <strong>ES</strong>, a suite of other documents accompanies the application <strong>for</strong><br />

planning permission and should be read in conjunction with the <strong>ES</strong>. These are:<br />

• Planning <strong>Statement</strong> (PS), which assesses the proposed wind farm in the context of<br />

adopted and emerging planning policies and other material considerations, setting out<br />

the planning and policy arguments <strong>for</strong> and against the proposed wind farm, and<br />

concluding with recommendations about the overall acceptability of the proposals in<br />

relation to the planning and policy context. The PS also includes a description of non-<br />

EIA topics such as telecommunications and aviation impact.<br />

• A Pre Application Consultation (PAC) Report, which details the consultation<br />

undertaken and summarises the key comments from consultees and how these have<br />

been considered within the project design at various stages.<br />

• A Design and Access <strong>Statement</strong> (DAS) which explains the design principles and<br />

concepts that have been applied to the development and how issues relating to access<br />

<strong>for</strong> traffic and pedestrians (including disabled people) have been dealt with where<br />

relevant, so as to bring <strong>for</strong>ward proposals <strong>for</strong> an inclusive environment and the<br />

creation of a sustainable approach to access.<br />

1.2 Overview of the Proposed Development<br />

1.2.1 PfR was established to facilitate renewable energy projects primarily on land controlled by<br />

public sector bodies. PfR has been working in partnership with FCS <strong>for</strong> over two years to<br />

establish the viability of the site at Carron Valley <strong>for</strong> a wind farm of this scale.<br />

1.2.2 The project is described as:<br />

“Application <strong>for</strong> planning permission <strong>for</strong> the erection, 25 year operation and<br />

subsequent decommissioning of a wind energy development comprising fifteen wind<br />

turbines, each with a maximum overall height (to vertical blade tip) of up to 126<br />

meters, and ancillary development including new access tracks, modification to<br />

existing tracks and improved site access, temporary construction compound, hard<br />

standing areas, control building and cabling, anemometry mast and temporary borrow<br />

pits."<br />

1.2.3 A key objective of the proposed wind farm is to generate approximately 98.55 gigawatt-hours<br />

(GWh) of renewable energy, thereby preventing approximately 42,376 tonnes of CO 2 being<br />

emitted each year and producing enough energy to supply up to of up to 22,081 average<br />

households in Britain (see Chapter 6: Climate Change and Atmospheric Emissions).<br />

1.2.4 In summary, the proposed wind farm comprises the following elements, which are described<br />

in more detail in Chapter 4: Description of the Proposed Development. The site layout is<br />

presented in Figure 1.2, and the main elements of the proposed wind farm are presented in<br />

Figures 4.1 to 4.9.<br />

• 15 variable pitch (three-bladed) wind turbines each to a maximum of 126 m to tip and a<br />

generating capacity of up to 3 MW;<br />

• 15 circular rein<strong>for</strong>ced concrete foundations of approximate 21 m diameter (typically<br />

containing approximately 727 m 3 structural concrete and 65 tonnes of high yield steel<br />

rein<strong>for</strong>cement);<br />

• Crane hard-standing areas adjacent to each wind turbine (approximate dimensions<br />

45 m x 25 m);<br />

• Underground electrical and SCADA 1 cabling linking each wind turbine with the site<br />

control building;<br />

• A single-storey, pitched roof control building comprising of a control room, switch room<br />

and metering room (typical dimensions are 5 m x 10 m x 5.5 m);<br />

• One permanent anemometry mast at a height equivalent to the maximum hub height<br />

depending on the selected turbine (see Section 4.3), there<strong>for</strong>e of up to 85 m high;<br />

• 9.34 km of permanent access tracks from the site entrance to the turbines and<br />

ancillary development (of which 6.24 km is existing <strong>for</strong>est track);<br />

• 7 m wide crossing points along the access tracks at typically 250 m intervals and 30 m<br />

long passing places at a distance of the order of 500 m apart;<br />

• A temporary hard-cored construction compound (approximately 50 m x 50 m to locate<br />

a refuelling area, materials storage, batching facility and welfare facilities);<br />

• Three borrow pits to provide material <strong>for</strong> construction aggregate, with the potential to<br />

provide an estimated 67,500 m 3 of material, representing about twice the estimate of<br />

aggregate volume required (see Appendix 13.1);<br />

• Upgrading a total of six watercourse crossings (see Appendix 13.3).<br />

1.2.5 The final choice of turbine <strong>for</strong> this site will depend on which turbine models are available in<br />

the UK market and the outcome of a competitive tendering exercise if planning permission is<br />

granted. The site has been designed to accommodate turbines with an installed capacity of<br />

3 MW. PfR has identified two possible turbine models with an ‘installed capacity’ of 3 MW<br />

which are potentially suitable (‘installed capacity’ is the theoretical maximum amount of<br />

electricity which can be produced at any one time), and has there<strong>for</strong>e assumed the “worst<br />

case” turbine dimensions to in<strong>for</strong>m those technical assessments that are based specifically<br />

upon the characteristics of the turbines. This is explained further in Chapter 4: Description of<br />

the Proposed Development.<br />

<strong>Partnerships</strong> <strong>for</strong> <strong>Renewables</strong><br />

1.3.1 PfR was set up by the Carbon Trust in 2006 to develop, construct and operate renewable<br />

energy projects primarily on public sector land. The public sector can play a significant part<br />

in the ef<strong>for</strong>t to increase renewables capacity, as public sector bodies own approximately<br />

10 % of the land in the UK (over one million hectares) and thousands of buildings.<br />

1.3.2 Carbon Trust Enterprises remains PfR’s single largest shareholder with backing from two<br />

major private sector shareholders (the InfraRed Environmental Infrastructure Fund (<strong>for</strong>merly<br />

the HSBC Environmental Infrastructure Fund) and OP Trust, a Canadian public sector<br />

pension fund).<br />

1.3.3 PfR works primarily in partnership with public sector bodies throughout the entire<br />

development process and covers all development costs. Focused on a development process<br />

tailored to the specific needs of the public sector, PfR provides a way <strong>for</strong> public sector bodies<br />

to access the economic and environmental benefits associated with renewable energy<br />

projects.<br />

1.3.4 In addition to FCS, PfR is currently working with a variety of public sector bodies across the<br />

UK including the Environment Agency, the Ministry of Justice, British Waterways, the Coal<br />

Authority, Clackmannanshire Council and a number of other local authorities and education<br />

establishments. PfR has achieved development consent <strong>for</strong> three onshore wind energy<br />

projects to date, at Stand<strong>for</strong>d Hill, Boddington and Oakdale.<br />

1.3.5 Further in<strong>for</strong>mation about PfR and its public sector partners can be found at www.pfr.co.uk.<br />

Forestry Commission Scotland – Scottish Lowlands Forest District<br />

1.3.6 Forest Enterprise Scotland is the Forestry Commission Scotland’s operating arm delivering<br />

the Forest Strategy on the National Forest Estate. Scottish Lowlands Forest District is<br />

working with PfR to assist in the delivery of its economic and climate change objectives set<br />

by Government and the Forestry Commission as described below.<br />

1.3.7 The Scottish Forestry Strategy (Scottish Executive, 2006) sets out the Government’s aims<br />

and objectives <strong>for</strong> all <strong>for</strong>estry in Scotland. It describes how <strong>for</strong>estry will deliver diverse<br />

benefits to the people, economy and environment of Scotland. The strategy describes at<br />

Outcome 3 that in helping to tackle climate change, <strong>for</strong>est managers should “encourage [..]<br />

renewable energy projects on <strong>for</strong>est land”. This is rein<strong>for</strong>ced in the National Forest Estate<br />

Strategic Plan 2009 – 2013 (Forestry Commission Scotland, 2009a) and the Forestry<br />

Commission’s Climate Change Action Plan 2009 – 2011 (Forestry Commission Scotland,<br />

2009b) where one of the key actions is to:<br />

“In co-operation with other organisations working to develop the use of renewable<br />

energy, promote the use of <strong>for</strong>est land <strong>for</strong> all <strong>for</strong>ms of renewable energy production,<br />

subject to appropriate environmental and planning safeguards.”<br />

1.3.8 The Scottish Lowlands Forest District Strategic Plan 2009 - 2013 (Forestry Commission<br />

• SL 3.13 – Seek the best and most reliable returns from developments to support our<br />

objectives locally and nationally, supported by expert help and well trained staff (key<br />

theme 3).<br />

1.3.9 By developing renewable energy projects, the Forestry Commission is helping to limit and<br />

adapt to the effects of climate change, reduce dependency on fossil fuels and help develop a<br />

low-carbon economy. It is also securing economic benefits <strong>for</strong> the Forestry Commission and<br />

local communities. These economic benefits are both directly identified as income to the<br />

Forestry Commission and local communities as well as indirect benefits to the rural economy.<br />

Working in Partnership – FCS and PfR<br />

1.3.11 The proposed wind farm is being developed by PfR in partnership with FCS. The partnership<br />

runs over two <strong>for</strong>estry districts, Scottish Borders and Lowlands. Initial screening of the two<br />

districts identified over a dozen sites with potential ranging from single turbine projects to<br />

strategic scale developments. It is expected that the portfolio of sites will deliver around 250<br />

MW of installed capacity.<br />

1.3.12 This working relationship ensures optimal compatibility between <strong>for</strong>est management and<br />

benefits and wind energy production. The projects are carefully designed to work well with<br />

existing <strong>for</strong>estry operations, provide opportunities to enhance biodiversity and encourage<br />

local communities to build a real stake in projects that are local to them.<br />

1.3.13 The structure of the partnership involves a staged approach of development, where the<br />

existing Forest Design Plan in<strong>for</strong>ms the wind farm design and acceptability of wind turbines<br />

and associated infrastructure, notwithstanding that the existing <strong>for</strong>est management is part of<br />

an overall set of constraints that affect the design of the proposal.<br />

1.3.14 FCS’s extensive knowledge of the Carron Valley area in terms of environmental and technical<br />

issues has been key in understanding the characteristics of the development site.<br />

1.3.15 Chapter 3: Design Evolution of this <strong>ES</strong> describes how the existing Forest Design Plan and<br />

<strong>for</strong>est management have in<strong>for</strong>med the design of the proposed wind farm. Chapter 4:<br />

Introduction


Carron Valley Wind Farm<br />

2 The Environmental Impact Assessment and Scoping<br />

Process<br />

2.1 Overview<br />

Background<br />

2.1.1 EIA is a systematic process that must be followed <strong>for</strong> certain categories of project be<strong>for</strong>e they<br />

can receive development consent. EIA aims to identify the significant environmental effects<br />

of a project. This helps to ensure that the importance of the predicted effects and the<br />

measures proposed to address them are properly understood by the public, and the local<br />

authority be<strong>for</strong>e it makes a decision.<br />

2.1.2 In<strong>for</strong>mation describing the development and its environmental effects are presented in an <strong>ES</strong>.<br />

The EIA process that culminates in the completion of the <strong>ES</strong> has a number of key<br />

characteristics:<br />

• It should be systematic, comprising a sequence of tasks defined both by regulation and<br />

by practice;<br />

• It should be analytical, requiring the application of specialist skills from the<br />

environmental sciences;<br />

• It should be impartial, its objective being to in<strong>for</strong>m decision-making rather than to<br />

promote the project;<br />

• It should be consultative, with provision being made <strong>for</strong> obtaining in<strong>for</strong>mation and<br />

feedback from interested parties including local authorities, members of the public and<br />

statutory and non statutory agencies; and<br />

• It should be iterative, allowing opportunities <strong>for</strong> environmental concerns to be<br />

addressed during the planning and design of a project.<br />

2.1.3 Typically, a number of design iterations take place in response to environmental constraints<br />

identified during the EIA process (i.e. incorporating mitigation measures to avoid, reduce,<br />

offset or compensate <strong>for</strong> identified adverse effects or conversely creating opportunities <strong>for</strong><br />

positive effects or enhancements). The design evolution process that has been followed in<br />

order to take account of environmental constraints and build-in appropriate mitigation to the<br />

proposed development is described fully in Chapter 3: Design Evolution. Further topicspecific<br />

mitigation measures are presented in the corresponding topic chapters and<br />

summarised in Chapter 16: Summary of Effects and Mitigation.<br />

EIA Regulations<br />

2.1.4 Schedule 1 of the EIA Regulations 1 lists those developments <strong>for</strong> which an EIA is mandatory.<br />

Schedule 2 of the EIA Regulations lists developments <strong>for</strong> which the need <strong>for</strong> an EIA is<br />

determined on a case-by-case basis (i.e. if significant environmental effects are likely), whilst<br />

Schedule 3 describes indicative thresholds to be used to determine if a Schedule 2<br />

development is an “EIA development”. Where an EIA is required, environmental in<strong>for</strong>mation<br />

must be provided by the applicant in an <strong>ES</strong>. Schedule 4 specifies the in<strong>for</strong>mation that must<br />

or may be provided in the <strong>ES</strong>.<br />

2.1.5 Most wind energy developments fall within Schedule 2 and, where the need <strong>for</strong> EIA is not<br />

certain, the developer can apply to the determining authority <strong>for</strong> a screening opinion. Due to<br />

the scale and nature of the proposed wind farm, a screening exercise was not carried out as<br />

the need <strong>for</strong> an EIA was not considered to be in doubt. PfR also recognised that the EIA<br />

process can play an important role in developing the design of the proposals to minimise<br />

adverse environmental effects and to maximise environmental benefits, and was there<strong>for</strong>e<br />

committed to proceeding with the EIA and scheme evolution.<br />

2.1.6 Whilst it is considered that the proposed wind farm has the potential <strong>for</strong> significant<br />

environmental effects, this does not mean that a significant effect is the ultimate conclusion of<br />

the EIA. The EIA process promotes the identification of potential adverse effects and<br />

incorporation of environmental measures into the design of the development, or the method<br />

of construction and operation that may reduce or eliminate any negative effects or further<br />

enhance positive effects.<br />

Topics to be Addressed<br />

2.1.7 Schedule 4 of the Regulations specifies that the <strong>ES</strong> should describe those “aspects of the<br />

environment likely to be significantly affected by the development, including, in particular<br />

population, fauna, flora, soil, water, air, climatic factors, material assets, including the<br />

architectural and archaeological heritage, landscape and the inter relationship between the<br />

above factors.”<br />

2.1.8 Establishing which aspects of the environment and associated issues are relevant <strong>for</strong> a<br />

particular project is captured through the EIA Scoping process which is described further in<br />

Section 2.2.<br />

Spatial Scope of the EIA<br />

2.1.9 In its broadest sense, the spatial scope is the area over which changes to the environment<br />

would occur as a consequence of the development. In practice, an EIA should focus on<br />

those areas where these effects are likely to be significant.<br />

2.1.10 The spatial scope varies between environmental topic areas. For example, the effect of a<br />

proposed wind energy development on the landscape resource and visual amenity is<br />

generally assessed within a zone of up to 35 km from the site boundary, whilst noise effects<br />

are assessed within a much smaller area encompassing the most affected properties close to<br />

the proposed site. Where necessary, the required spatial scope <strong>for</strong> individual topic<br />

assessments are provided in the specialist chapters.<br />

Temporal Scope of the EIA<br />

2.1.11 The timescale of the proposed development is assumed to run from the intended start of<br />

construction through the intended 25 year operational life of the wind farm. The construction<br />

period is estimated to be around 20 months.<br />

2.1.12 Effects are generally considered in relation to the following key stages of the development:<br />

• Construction – effects may arise from the construction activities themselves, or from<br />

the temporary occupation of land. Effects are often of limited duration although there is<br />

Carron Valley Wind Farm<br />

potential <strong>for</strong> permanent effects. Where construction activities create permanent<br />

change, the effects will obviously continue into the operational period;<br />

• Operation – effects may be permanent, or (as is typical with wind power<br />

developments) they may be temporary, intermittent, or limited to the life of the<br />

development until decommissioning; and<br />

• Decommissioning – effects may arise from the decommissioning activities<br />

themselves, or from the temporary occupation of land. The effects would generally be<br />

temporary and of limited duration and additional permanent change (unless associated<br />

with restoration) would normally be unlikely.<br />

Definition of the Baseline<br />

2.1.13 The environmental assessment process does not merely consider the effects of the proposed<br />

development against the conditions as they are now, but instead makes the assessment<br />

against what is described as the “Do-minimum” scenario; that is, what could be reasonably<br />

expected to have occurred over the same timescale if the proposed development did not go<br />

ahead.<br />

2.1.14 As the site is a commercial <strong>for</strong>estry plantation, the environmental baseline is not fixed, and it<br />

is there<strong>for</strong>e necessary to determine changes that are predicted to take place between the<br />

time of site surveys <strong>for</strong> the EIA and the time of construction commencement. Definition of the<br />

<strong>for</strong>estry baseline used in the EIA is discussed further in Chapter 4: Description of the<br />

Proposed Development.<br />

2.2 Scoping<br />

Overview<br />

2.2.1 Scoping is the process of identifying those aspects of the environment and associated issues<br />

that need to be considered when assessing the potential effects of a particular development<br />

proposal. This recognises that there may be some environmental elements where there will<br />

be no significant issues or likely effects resulting from the development and hence where<br />

there is no need <strong>for</strong> further investigation to be undertaken.<br />

2.2.2 Scoping is undertaken through consulting organisations and individuals with an interest in<br />

and knowledge of the site, combined with the professional judgement and experience of the<br />

EIA team. It takes account of published guidance, the likely effects of the kind of<br />

development under consideration and the nature and importance of the environmental<br />

resources that could be affected.<br />

2.2.3 Regulation 7 of the EIA Regulations sets out the procedures required to obtain a <strong>for</strong>mal<br />

scoping opinion from the determining authority, in this case Stirling Council.<br />

2.2.4 The purpose of scoping is to:<br />

• Ensure that statutory consultees and other bodies with a particular interest in the<br />

environment are in<strong>for</strong>med of the proposal and provided with an opportunity to<br />

comment at an early stage in the EIA process;<br />

• Obtain baseline in<strong>for</strong>mation regarding existing environmental site conditions;<br />

• Establish key environmental issues and identify potential effects to be considered<br />

during the EIA;<br />

• Identify those issues which are likely to require more detailed study and those which<br />

can be justifiably excluded from further assessment;<br />

• Provide a means of confirming the most appropriate methods of assessment.<br />

Scoping Report<br />

2.2.5 The initial proposed EIA scope was <strong>for</strong>mulated based on desk-based and field-based<br />

knowledge of the site and prior experience of other wind farm EIAs. A Scoping Report,<br />

setting out the proposed scope, was prepared by PfR and submitted to Stirling Council in<br />

September 2011 (see Appendix 2.1) together with a request <strong>for</strong> a <strong>for</strong>mal Scoping Opinion.<br />

To expedite the scoping process, at the request of Stirling Council this was also submitted<br />

directly to the adjoining local authorities of East Dunbartonshire, North Lanarkshire, and<br />

Falkirk Council as well as to Scottish Environment Protection Agency (SEPA), Scottish<br />

Natural Heritage (SNH), Historic Scotland, Loch Lomond and the Trossachs National Park<br />

Authority and Scottish Water.<br />

The Scoping Opinion<br />

2.2.6 The <strong>for</strong>mal Scoping Opinion was issued on 5 January 2012. The responses from the<br />

following consultees were included:<br />

• SNH;<br />

• SEPA;<br />

• Historic Scotland;<br />

• Loch Lomond and the Trossachs National Park Authority;<br />

• Transport Scotland;<br />

• Stirling Council (Roads, Environmental Health);<br />

• Scottish Government (noise);<br />

• North Lanarkshire Council;<br />

• East Dunbartonshire Council; and<br />

• Falkirk Council.<br />

2.2.7 A copy of scoping responses received from consultees, and the official Stirling Council<br />

scoping opinion is presented in Appendix 2.2.<br />

The Agreed Scope of the EIA<br />

2.2.8 The way in which the scoping opinion and responses from the above consultees, together<br />

with additional consultations undertaken as part of the EIA process, have been addressed in<br />

the <strong>ES</strong> is set out in Table 2.1 below. The scoping process enabled a continued dialogue with<br />

consultees. Throughout the assessment process the relevant consultees have been<br />

consulted by those conducting the relevant aspects of the EIA. Further consultation has<br />

been undertaken by PfR as detailed in Pre-Application Consultation (PAC) Report submitted<br />

in support of the application <strong>for</strong> planning permission.<br />

• Collection and collation of existing baseline in<strong>for</strong>mation about the receiving<br />

environment and original surveys to fill any gaps in knowledge or to update any historic<br />

in<strong>for</strong>mation, along with identification of any relevant trends in, or evolution of, the<br />

baseline;<br />

• Ongoing consultation with experts and relevant consultees in response to emerging<br />

study findings;<br />

Carron Valley Wind Farm<br />

• Consideration of the potential effects of the development on the baseline, followed by<br />

identification of design changes and mitigation measures to seek to avoid or reduce<br />

any predicted adverse effects;<br />

• Engagement with other technical topic specialists and engineers/designers in a design<br />

iteration process seeking to optimise the scheme <strong>for</strong> the differing environmental<br />

effects;<br />

• Assessment of the final scheme design and evaluation of the significance of any<br />

residual effects; and<br />

• Compilation of the <strong>ES</strong> chapter.<br />

2.3.3 In reality, many of the effects are relevant to more than one environmental topic area, and<br />

careful attention has been paid to interrelationships to avoid overlap or duplication between<br />

topic chapters. For example, visual effects including those affecting cultural heritage features<br />

are addressed in the landscape and visual chapter, with cross-references in the cultural<br />

heritage chapter as appropriate. Similarly, secondary effects on ecological resources arising<br />

from hydrological change would be considered in the ecology chapter with a cross-reference<br />

to the relevant direct effect in the water chapter.<br />

2.3.4 The following <strong>for</strong>mat has been adopted <strong>for</strong> the presentation of in<strong>for</strong>mation within the <strong>ES</strong>. In<br />

some cases, technical data and analysis is contained within a Technical Appendix that is<br />

bound separately from the main <strong>ES</strong>.<br />

• Introduction and overview – setting the scene <strong>for</strong> the topic, the nature of the<br />

receptors to be considered, and how the proposals might cause change;<br />

• Methodology – describing how receptors were identified through a scoping process,<br />

along with the specific methods used <strong>for</strong> data gathering, predicting effects and<br />

evaluating significance of effects;<br />

• Baseline in<strong>for</strong>mation – describing the current state and circumstances of the<br />

receptors and changes that might be expected in advance of the development being<br />

implemented and during its 25 year operational lifetime;<br />

• Topic specific design evolution – describing how the scheme has been designed<br />

considering a particular receptor or effect, <strong>for</strong> example incorporating planting to provide<br />

a particular habitat on site or screening <strong>for</strong> a particular view which <strong>for</strong>ms part of the<br />

scheme design;<br />

• Potential significant effects of the scheme prior to mitigation – an assessment of<br />

the nature of the effects likely to arise as a result of implementing the development as<br />

set out in Chapter 4: Description of the Proposed Development;<br />

• Mitigation and enhancement measures – identifying topic specific measures which<br />

would be implemented in order to avoid, reduce, control, manage or compensate<br />

potential significant effects. It is expected these measures would be secured via a<br />

planning condition. These do not include measures required to comply with legal<br />

requirements, as these are part of the scheme as set out in Chapter 4: Description of<br />

the Proposed Development. Enhancement measures are also identified;<br />

• Assessment of residual effects – an assessment of the significance of the effects<br />

likely to arise as a result of implementing the final design of the project after the<br />

mitigation measures have been employed, considering the 25 year operational lifetime<br />

of the project. A table summarising the likely significant environmental effects after<br />

mitigation is presented in this section;<br />

• Cumulative effects – identifying potentially significant effects arising from the<br />

proposed project alongside other major developments in the planning process but not<br />

• References.<br />

Defining Significance of Effects<br />

2.3.5 Development proposals affect different environmental elements to differing degrees and not<br />

all of these are of sufficient concern to warrant detailed investigation or assessment within the<br />

EIA process. The EIA Regulations identify those that warrant investigation as those that are<br />

“likely to be significantly affected by the development”.<br />

2.3.6 Conclusions about significance are derived with reference to available in<strong>for</strong>mation about the<br />

project description and the environmental receptors (or ‘receiving environment’), and to<br />

predictions about the potential changes that the proposed development would cause to the<br />

affected receptors.<br />

2.3.7 In each of the environmental topic chapters, professional judgement is used in combination<br />

with relevant guidance to assess the interaction of the receptor’s value (importance or<br />

sensitivity) against the predicted magnitude of change to identify the overall significance of<br />

effect. Best practice EIA typically goes beyond this to identify a level of significance when the<br />

predicted effect is determined to be significant. In some cases, the judgement can be guided<br />

by quantitative values, whilst in other cases qualitative descriptions are used.<br />

2.3.8 In general terms, and in order to assist interpretation of the final results of the EIA, receptor<br />

value, magnitude of change and significance of effect <strong>for</strong> each environmental topic are<br />

described consistently throughout the <strong>ES</strong>, as shown in Table 2.2. A definition of how the<br />

terms are derived <strong>for</strong> each topic is set out in the specialist topic chapters. Where this<br />

approach is inappropriate, the relevant explanation and amended descriptions of receptor<br />

importance, magnitude of change and significance of effect are provided.<br />

2.3.9 The approach to assigning significance of effect is derived from a variety of sources including<br />

industry and professional guidance, codes of practice, advice from statutory consultees and<br />

other stakeholders, as well as expert judgement of the EIA practitioners undertaking the<br />

technical assessments<br />

2.3.10 One of three methods to determining the significance of effect is employed depending on the<br />

assessment topic: matrix (as shown in Table 2.2), criteria (as shown in Table 2.3), and<br />

descriptor (as identified in paragraph 2.3.14).<br />

2.3.11 Where sufficient in<strong>for</strong>mation exists to value a receptor and to understand the magnitude of<br />

the effect or change, the assessment methodology often uses a matrix to determine<br />

significance of the effect. In this approach significance of effect in broad terms is determined<br />

by a combination of the value of the receptor being affected and the magnitude of the effect.<br />

This is the case <strong>for</strong> example with ecological and cultural heritage designations which have<br />

clear relative values (e.g. a site designated at a national level is valued more highly than one<br />

that is undesignated or designated at a local level).<br />

2.3.12 Each topic assessment has been carried out using the significance levels and associated<br />

criteria derived from relevant guidance <strong>for</strong> that topic. Where possible topic chapters have<br />

aligned their significance levels to the criteria set out in Tables 2.2 and 2.3 and this is set out<br />

in the methodology section of each assessment topic chapter.<br />

2.3.13 In the absence of a recognised assessment methodology general levels of significance using<br />

criteria defined in DMRB2 <strong>Vol</strong>ume 11:Environmental Assessment (2009) are frequently<br />

employed (Table 2.3 is based on significance criteria set out in the DMRB). This is the case<br />

<strong>for</strong> example in assessing the significance of effect on the water environment. These levels of<br />

significance apply to both adverse and beneficial effects. In some instances a further<br />

category of ‘no effect’ may be used.<br />

2.3.14 For some topics where it is very difficult to value an asset and/or quantify the magnitude of<br />

the effect (e.g. socio economics or waste) a simple descriptor – beneficial, neutral or adverse<br />

is used to describe the significance of the effect.<br />

Criteria<br />

Only adverse effects are assigned this level of importance as they represent key<br />

factors in the decision-making process. These effects are generally, but not<br />

exclusively, associated with sites and features of international, national or<br />

regional importance that are likely to suffer a most damaging effect and loss of<br />

resource integrity. A major change at a regional or district scale site or feature<br />

may also enter this category.<br />

These beneficial or adverse effects are likely to be very important considerations<br />

at a local or district scale and, if adverse, are potential concerns to the scheme<br />

and may become material in the decision making process.<br />

These beneficial or adverse effects while important at a local scale are not likely<br />

to be key decision making issues. Nevertheless, the cumulative effect of such<br />

issues may influence decision making if they lead to an increase in the overall<br />

adverse effects on a particular area or on a particular resource.<br />

These beneficial or adverse effects may be raised as local factors but are<br />

consideration of mitigation or compensation measures.<br />

No discernible effect within the normal bounds of variation or within the margin of<br />

<strong>for</strong>ecasting error. Not normally considered by the decision maker.<br />

2.3.15 While effects are considered to fall into one of five categories ranging from ‘negligible’,<br />

‘slight‘, ‘moderate’, ‘substantial’ and ‘very substantial’ in the effects matrix presented in Table<br />

2.2, it is generally only those effects that fall into the ‘moderate’, ‘substantial’ or ‘very<br />

substantial’ category that are considered to be the significant environmental effects arising<br />

from the construction, operation and decommissioning of the development. It should however<br />

be noted that different specialist topics within the <strong>ES</strong> may use a different approach to<br />

identifying significant effects. The use of the categories of ‘slight’ or ‘negligible’ is used in<br />

acknowledgement that there may be a range of effects and it is also used to assess where,<br />

cumulatively, several effects of moderate or less could be deemed to combine to be a<br />

substantial or greater effect. Further guidance is contained within paragraph 94 of Circular 3,<br />

2011, The Town and Country Planning (Environmental Impact Assessment)(Scotland)<br />

Regulations 2011 which states:<br />

“Whilst every <strong>ES</strong> should provide a full factual description of the development, the<br />

emphasis of Schedule 4 is on the ‘main’ or ‘significant’ environmental effects to which<br />

a development is likely to give rise. Other impacts may be of little or no significance <strong>for</strong><br />

the particular development in question and will need only very brief treatment to<br />

indicate that their possible relevance has been considered.”<br />

Type of Effect<br />

2.3.16 The EIA Regulations require consideration of a variety of types of effect, namely<br />

direct/indirect, secondary, cumulative, positive/negative, short/medium/long-term, and<br />

permanent/temporary. In this <strong>ES</strong>, effects are considered in terms of how they arise, their<br />

valency (i.e. whether they are positive or negative) and duration. Each will have a source<br />

originating from the development, a pathway and a receptor.<br />

2.3.17 Most predicted effects will be adverse/negative or beneficial/positive, direct, indirect,<br />

secondary or cumulative, temporary or permanent, short, medium or long term. The nature<br />

of each of these effects is defined in Table 2.4, with further discussion relating to cumulative<br />

effects provided in the section below. In some cases it is appropriate to identify that the<br />

interpretation of a change is a matter of personal opinion, and such effects will be described<br />

as ‘subjective’.<br />

2.3.18 The temporal scope of environmental effects is stated where known. Effects are typically<br />

described as:<br />

• Temporary – these are likely to be related to a particular activity and will cease when<br />

the activity finishes. The terms ‘short-term’ and ‘long-term’ may also be used to provide<br />

a further indication of how long the effect will be experienced; and<br />

Cumulative Effects<br />

2.3.19 According to the Guidelines <strong>for</strong> Cumulative Effects Assessment prepared <strong>for</strong> the EC by Hyder<br />

in 1999, cumulative effects are defined as “impacts that result from incremental changes<br />

caused by other past, present, or reasonably <strong>for</strong>eseeable actions together with the project”.<br />

2.3.20 Major developments that should be considered <strong>for</strong> the cumulative effects assessment are<br />

identified within the following categories:<br />

• Built and operational development;<br />

• Development under construction;<br />

• Application(s) permitted but which are not yet implemented;<br />

• Submitted applications not yet determined, and which, if permitted, would affect the<br />

proposed development in the scoping request; and<br />

• Development identified in the adopted and emerging development plan (with<br />

appropriate weight being given as they move closer to adoption) recognising that much<br />

in<strong>for</strong>mation on any relevant proposals will be limited.<br />

2.3.21 Not all of the cumulative developments identified would necessarily have a cumulative effect<br />

in respect of any particular assessment topic. Where cumulative effects are potentially<br />

relevant, each assessment topic chapter has determined which of the developments listed<br />

should be considered.<br />

2.3.22 A detailed discussion of the cumulative developments taken into account is provided in the<br />

respective chapters of the <strong>ES</strong>.<br />

2.4 Consideration of Alternatives<br />

2.4.1 The EIA Regulations require the <strong>ES</strong> to include “an outline of the main alternatives studied by<br />

the applicant or appellant and an indication of the main reasons <strong>for</strong> his choice”.<br />

2.4.2 National planning and energy policy makes it clear that there is no requirement <strong>for</strong> renewable<br />

energy developments to demonstrate an overall need <strong>for</strong> new renewable generation or a<br />

need to be located in a specific location. The Energy Review of 2006 and the White Paper of<br />

2007 both contained a <strong>Renewables</strong> <strong>Statement</strong> of Need which states: “Renewable energy as<br />

a source of low-carbon, indigenous electricity production is central to reducing emissions and<br />

maintaining the reliability of our energy supplies at a time when indigenous fossil fuels are<br />

declining more rapidly than expected”.<br />

2.4.3 The 2007 Energy White Paper provides further clarification stating at section 5.3.67:<br />

“Recognising the particular difficulties faced by renewables in securing planning<br />

consent, the Government is also:<br />

• Underlining that applicants will no longer have to demonstrate either the overall<br />

need <strong>for</strong> renewable energy or <strong>for</strong> their particular proposal to be sited in a<br />

particular location”<br />

2.4.4 There is nowhere in the Town and Country Planning (Scotland) Act as amended by The<br />

Planning etc (Scotland) Act 2006 that expressly or otherwise requires planning authorities to<br />

consider alternative sites in the determination of the application. Instead, the emphasis of the<br />

Act is on the consideration of the particular application in question.<br />

2.4.5 Planning Advice Note 58 (PAN 58) states in paragraph 70 that:<br />

“In presenting alternatives, applicants and planning authorities need to recognise the<br />

constraints of commercial confidentiality and the potential <strong>for</strong> creating blight, especially<br />

where a development is part of a programme and the alternatives are projects which<br />

may come <strong>for</strong>ward in due course.”<br />

2.4.6 PAN 58 continues in paragraph 71 that:<br />

“The [EIA] Regulations do not require the applicant to ‘invent’ alternatives where none<br />

has been considered (although the lack of alternatives should be explained). It is<br />

accepted that the alternatives available will be constrained by economic and<br />

operational reasons. The planning authority should determine the planning application<br />

on the merits of the proposal be<strong>for</strong>e them and not on the merits of potential<br />

alternatives (<strong>for</strong> some projects however the existence or otherwise of a feasible<br />

alternative may be a material consideration in the determination of the application).”<br />

2.4.7 Scottish Planning Policy (SPP) does not identify in the criteria <strong>for</strong> determining wind farm<br />

applications the requirement to consider alternative sites. However it provides, in paragraph<br />

187 that “planning authorities should support the development of wind farms in locations<br />

where the technology can operate efficiently and environmental and cumulative impacts can<br />

be satisfactorily addressed.”<br />

2.4.8 The policy context if there<strong>for</strong>e clear that there is neither a requirement to justify the viability of<br />

a wind energy proposal nor the need <strong>for</strong> it to be located in a particular location.<br />

Nevertheless, Chapter 3: Design Evolution of this <strong>ES</strong> describes the site identification process<br />

and design criteria. In EIA terms, the requirement is only to report on alternatives that have<br />

been considered. The examination of alternatives in this <strong>ES</strong> is there<strong>for</strong>e restricted as<br />

appropriate to alternative design solutions that were considered <strong>for</strong> the site in question in<br />

terms of factors such as site layout, design, turbine height and turbine numbers, and the<br />

environmental effects of the options considered.<br />

2.5 Micro-siting<br />

2.5.1 Following submission of the application, elements of the proposed development may be<br />

subject to further, minor refinement, known as ‘micro-siting’, within the site boundary. Micrositing<br />

reflects the need to:<br />

• Take into account statutory and non-statutory consultee responses received during the<br />

planning application determination process;<br />

• Reflect the findings of post-application and post-consent ground investigations; and<br />

• Reflect any minor relocation required <strong>for</strong> ecological or archaeological reasons.<br />

2.5.2 In permitting a micro-siting allowance it is important to note that no development will be<br />

undertaken that would increase the potential level of effect on sensitive receptors and other<br />

constraints identified in this <strong>ES</strong>. For example, the stand-off distances identified in Chapter 3:<br />

Design Evolution would be maintained.<br />

2.5.3 In the event that Stirling Council is minded to grant consent <strong>for</strong> the proposed wind farm, the<br />

applicant respectfully requests a planning condition that, subject to the prior written approval<br />

of Stirling Council, allows the micro-siting of elements of the scheme up to 50 m from the<br />

location shown on approved plans except:<br />

• where this allowance encroaches outside of the red line boundary; and<br />

• where such a change would infringe upon the buffers used in the constraints mapping<br />

process shown on Figure 3.1.<br />

2.6 Decommissioning<br />

2.6.1 The proposed wind farm would have an operational life of approximately 25 years.<br />

Decommissioning would be carried out in accordance with legislative requirements at that<br />

time. However, if market conditions at that time indicate that it would be appropriate to<br />

extend the life of the wind turbine, then decommissioning could be deferred to a later date<br />

subject to the relevant statutory approvals.<br />

2.6.2 Decommissioning this far into the future is not an event that can be accurately assessed at<br />

this time due to changes in policy, legislation and technology. The assessment of the<br />

decommissioning phase is there<strong>for</strong>e limited to how the design of the proposed development<br />

and use of materials would enable a minimum of disruption to be achieved and the<br />

restoration of the site to its <strong>for</strong>mer use. The predicted effects from the decommissioning<br />

phase are likely to be similar to those likely during construction and this is the approach taken<br />

by the topic chapters.<br />

The EIA and Scoping Process


Carron Valley Wind Farm<br />

3 Design Evolution<br />

3.1 Introduction<br />

3.1.1 The Carron Valley site contains a complex range of environmental factors, visual impact<br />

issues and engineering constraints which need to be considered and balanced during the<br />

overall design of the site layout.<br />

3.1.2 Schedule 4 of the Town and Country Planning (Environmental Impact Assessment)<br />

(Scotland) Regulations 2011 (the EIA Regulations) also requires “an outline of the main<br />

alternatives studied by the applicant or appellant and an indication of the main reasons <strong>for</strong> his<br />

choice”.<br />

3.1.3 There are also requirements under the Controlled Activities (Scotland) Regulations 2005 to<br />

ensure that an assessment of alternatives is undertaken (e.g. Engineering in the Water<br />

Environment Good Practice Guide Construction of Rover Crossings First Edition, April 2008,<br />

document reference WAT-SG-25).<br />

3.1.4 This chapter functions as a design statement and outlines the site selection process<br />

undertaken by <strong>Partnerships</strong> <strong>for</strong> <strong>Renewables</strong> (PfR) and provides an overview of the site<br />

design considerations, key characteristics of the site and the evolution of the proposed wind<br />

farm layout in response to physical, technical and environmental constraints and<br />

requirements.<br />

3.1.5 The site selection process, the initial stage of the scheme development process, is<br />

undertaken on the basis of screening against high level characteristics such as wind<br />

resource, site capacity, designated areas, site access, proximity to settlements and proximity<br />

to the electricity grid.<br />

3.1.6 Once a site has been selected as potentially suitable to accommodate a wind farm, a more<br />

detailed analysis of the site is carried out. This includes factors such as consideration of<br />

relevant planning policy and taking into account the site specific characteristics and<br />

constraints. Detailed site specific characteristics and constraints, gathered through both<br />

desk-based and site survey work, are then used to in<strong>for</strong>m and constrain the location of<br />

turbines and associated infrastructure within the site as part of the design evolution process.<br />

3.1.7 This approach has enabled the findings of the EIA to guide the evolution of the proposed<br />

wind farm layout and <strong>for</strong> the site design to be modified in order to avoid, reduce or mitigate<br />

potentially negative environmental effects as far as possible. Feedback from consultation at<br />

all stages of the EIA process, as outlined in Chapter 2: The Environmental Impact<br />

Assessment and Scoping Process, has also fed into the design evolution.<br />

3.2 Planning Policy Context<br />

Scottish Planning Policy<br />

3.2.1 Scottish Planning Policy (SPP) (Scottish Government, 2010) provides advice on renewable<br />

energy development. This is relevant to site selection as planning authorities are encouraged<br />

to support the development of renewable energy technologies and to guide development to<br />

appropriate locations. Planning authorities should support communities and small<br />

businesses in developing such initiatives in an environmentally acceptable way.<br />

Carron Valley Wind Farm<br />

3.2.2 Factors relevant to the consideration of applications will depend on the scale of the<br />

development and its relationship with the surrounding area, but are likely to include:<br />

• landscape and visual impacts;<br />

• effects on the natural heritage and historic environment;<br />

• contribution of the development to renewable energy generation targets;<br />

• effects on the local and national economy and tourism and recreation interests;<br />

• benefits and disadvantages <strong>for</strong> communities;<br />

• aviation and telecommunications;<br />

• noise and shadow flicker; and<br />

• cumulative impacts.<br />

3.2.3 Planning authorities should set out in the development plan a spatial framework <strong>for</strong> onshore<br />

wind farms of over 20 MW generating capacity. Authorities may incorporate wind farms of<br />

less than 20 MW generating capacity in their spatial framework if considered appropriate.<br />

The spatial framework should identify:<br />

• Areas requiring significant protection because they are designated <strong>for</strong> their<br />

international or national landscape or natural heritage value, are designated as green<br />

belt or are areas where the cumulative impact of existing and consented wind farms<br />

limits further development;<br />

• Areas with potential constraints where proposals will be considered on their individual<br />

merits against identified criteria;<br />

• Areas of search where appropriate proposals are likely to be supported subject to<br />

detailed consideration against identified criteria.<br />

3.2.4 When identifying areas with potential constraints on wind farm development, planning<br />

authorities should consider the following:<br />

• The historic environment;<br />

• Areas designated <strong>for</strong> their regional and local landscape or natural heritage value;<br />

• Tourism and recreation interests;<br />

• Likely impacts on communities, including long term and significant impact on amenity;<br />

• Impact on aviation and defence interests, particularly airport and aerodrome operation,<br />

flight activity, tactical training areas, aviation and defence radar and seismological<br />

recording;<br />

• Impact on broadcasting installations, particularly maintaining transmission links.<br />

3.2.5 A separation distance of up to 2 km between areas of search and the edge of cities, towns<br />

and villages is recommended to guide developments to the most appropriate sites and to<br />

reduce visual impact, but decisions on individual developments should take into account<br />

specific local circumstances and geography. Development plans should recognise that the<br />

existence of these constraints on wind farm development does not impose a blanket<br />

restriction on development.<br />

Carron Valley Wind Farm<br />

Scottish Government Planning Advice - Onshore Wind Turbines<br />

3.2.6 SPP should be read with Scottish Government Planning Advice ”Onshore Wind Turbines”<br />

(2011); which contains some detailed planning advice and technical in<strong>for</strong>mation which has<br />

further assisted in the site selection process.<br />

3.2.7 In considering the landscape impacts of wind farms when determining planning applications,<br />

the guidance recognises that the receiving landscape features and the design of the<br />

development can play a significant role in ensuring the proposals are integrated into the<br />

landscape setting. It states that “the ability of the landscape to absorb development often<br />

depends largely on features of landscape character such as land<strong>for</strong>m, ridges, hills, valleys<br />

and vegetation. This can also be influenced by careful siting and the skills of the designer.”<br />

3.2.8 Other criteria identified in the guidance to be assessed in the determination of wind farm<br />

proposals include impacts on communities (as a result of shadow flicker, noise, electromagnetic<br />

interference and ice throw), aviation and other defence matters, road traffic impacts<br />

and cumulative impacts.<br />

Development Plan Policy<br />

3.2.9 Development Plan policies relevant to site selection and design include Stirling Council Local<br />

Plan Policy E10 which requires, amongst other criteria, that the siting and external<br />

appearance of apparatus have been chosen to minimise the impact on amenity, while<br />

respecting operational efficiency.<br />

3.2.10 In addition, the Stirling Council Supplementary Planning Guidance – Wind Turbines (March<br />

2011) sets out local guidance and criteria <strong>for</strong> wind farm proposals, including requiring that<br />

proposals are an appropriate scale, design and layout <strong>for</strong> the location.<br />

3.3 Site Identification and Selection<br />

3.3.1 The initial site selection process <strong>for</strong> the Carron Valley development proceeded in three<br />

stages as follows.<br />

3.3.2 PfR originally investigated over 30 Forestry Commission Scotland sites in the Borders and<br />

Lowlands Districts. These sites were screened against a number of set criteria, such as:<br />

• Indicative wind speed from the NOABL database;<br />

• Proximity to residential areas;<br />

• Proximity to grid;<br />

• Site access;<br />

• Available land area; and<br />

• Potential aviation issues.<br />

3.3.3 After the bulk screening, the sites were classified ‘good’, ‘medium’ and ‘low’, and ‘good’ sites<br />

were then screened further by using a Geographical In<strong>for</strong>mation System (GIS), and classified<br />

as having ‘best’, ‘medium’ or ‘low’ potential.<br />

3.3.4 Following the process above, a short list was created which prioritised development based on<br />

its potential. Carron Valley was part of the group with the best potential, as, <strong>for</strong> instance, the<br />

indicative wind speed varied from 6.5 – 9.5 m/s at 80 m hub height, main residential areas<br />

are at a sufficient distance, the available land area was very large, site access is deemed<br />

feasible and aviation constraints could be overcome by using the large area available.<br />

3.3.5 The second stage of the process was to carry out feasibility to confirm the site selection. This<br />

included a more detailed screening of the site, to include landscape and visual potential,<br />

potential cultural heritage issues, above mentioned technical constraints, and a political<br />

overview. Key risks were also identified. Further detail on the feasibility can be found in<br />

Section 3.5 below.<br />

3.3.6 The feasibility identified that Carron Valley has excellent potential <strong>for</strong> a wind farm, not only<br />

based on the above mentioned criteria that were concluded at the first stage, but also<br />

because of the landscape potential of the site, the absence of deep peat from the majority of<br />

the site and the potentially low environmental sensitivity. The key risks that were identified<br />

were aviation, landscape, cultural heritage and access constraints.<br />

3.3.7 The third stage, PfR’s first Project Development Phase (DP1), constitutes of mitigating key<br />

risks be<strong>for</strong>e proceeding towards the next phase which encompasses environmental survey<br />

work and EIA. By mitigation, PfR means mitigating risk that could potentially stop<br />

development. The identified risks have been mitigated in DP1 by consultation with the<br />

aviation stakeholders, creating a set-back distance to the Scheduled Monument on-site,<br />

identifying and contacting access landowners, and identifying key landscape areas within the<br />

site.<br />

3.4 Design Criteria<br />

3.4.1 The design solution <strong>for</strong> a site is based on consideration of the following criteria across all<br />

development phases, as more detailed in<strong>for</strong>mation becomes available.<br />

Technical Criteria<br />

3.4.2 A number of technical considerations are key to the site design process from the initial<br />

design, feeding through to the final design. These are set out below:<br />

• The NOABL UK Wind Speed Database confirmed that the wind speed on the site at a<br />

height of 80 m is between 6.5 m/s to 9.5 m/s which is considered favourable in terms<br />

of locating a proposed wind farm. An assessment into the wind resource was also<br />

carried out taking into account <strong>for</strong>estry cover, confirmed that the wind speed at the site<br />

at a height of 80 m is well over 7.00 m/s, also considered suitable in terms of locating a<br />

proposed wind farm.<br />

• There is a temporary anemometry mast currently installed on the site which has been<br />

monitoring wind speed from November 2011. The data has confirmed suitable wind<br />

speeds <strong>for</strong> locating a wind farm.<br />

• Considering the proposed location and specification of turbines must also take into<br />

account the height at which each will sit as, the higher the turbine, the higher the<br />

power output.<br />

• Optimising the layout to maximise the energy extraction from the wind is an important<br />

consideration. This is largely achieved by placing turbines at minimum distances apart<br />

in order to ensure adequate wind flow around turbines, minimise losses and avoid<br />

excessive wear and tear on the machinery. The prevailing wind direction is used to<br />

align the orientation of the turbines. An elliptical air flow buffer is placed around each<br />

proposed turbine equivalent to six times the rotor diameter in the down wind direction<br />

and four times the rotor diameter in the cross wind direction based on the assumed<br />

worst case turbine rotor diameter of 90 m (45 m blade length).<br />

• A key consideration when siting turbines is the steepness of the terrain on site. This<br />

affects not only the turbine siting but also the design of access tracks between the<br />

turbine locations. It is there<strong>for</strong>e important to consider this factor <strong>for</strong> reasons of health<br />

and safety and viability of the development in terms of construction and operation.<br />

• Complying with likely noise limits and protecting the noise amenity of residential<br />

properties.<br />

• Potential impacts of shadow flicker on residential and other properties.<br />

• Avoiding radar visibility and any potential influence on aviation safety.<br />

• Avoiding interference with telecommunication links and existing service infrastructure.<br />

Environmental Criteria<br />

3.4.3 The following environmental considerations are also taken into account in the design<br />

process:<br />

• Existing land uses;<br />

• Avoiding designated nature conservation sites and minimising impacts on areas of<br />

ecological value;<br />

• Minimising impacts on areas of ornithological value;<br />

• Avoiding designated sites of archaeological importance and minimise impacts on areas<br />

of undesignated archaeological interest and areas with archaeological potential;<br />

• Avoiding surface and groundwater resources and minimising indirect effects on these<br />

features; and<br />

• Utilising existing access and minimising lengths of new access tracks to reduce<br />

impacts and material requirements.<br />

Forest Design Plan Criteria<br />

3.4.4 The proposed amendment to the Forest Design Plan (FDP) <strong>for</strong> Cairnoch Hill was taken into<br />

consideration during the site design process. Turbine locations were chosen to fit in the<br />

amended FDP coupes, where possible.<br />

3.4.5 FCS will agree practices such as Short Rotation Forestry and Early Felling, as explained in<br />

Chapter 4: Description of the Proposed Development, with PfR based on the current turbine<br />

positions and layout, and to manage the <strong>for</strong>est with the wind farm in the most optimal way<br />

while ensuring compliance with and retention of UK Woodland Assurance Standard<br />

(UKWAS) certification.<br />

3.4.6 Further details of the FDP are provided within Chapter 4: Description of the Proposed<br />

Development.<br />

Landscape and Visual Criteria<br />

3.4.7 The Scottish Natural Heritage (SNH) Guidance Siting and Designing Windfarms in the<br />

Landscape (SNH, 2009) was taken into account during the design process. The Guidance<br />

seeks to ensure that wind farms are sited and designed well and identifies that the layout of a<br />

wind farm should relate to the specific characteristics of the landscape. many landscape and<br />

visual sensitivities can be addressed through good design in wind farm layout.<br />

3.4.8 The Guidance indicates a number of variables relating to key characteristics of wind farm<br />

design which were taken into account in the design of the proposed wind farm. These<br />

include:<br />

• Layout and number of turbines;<br />

• Size, design and proportion of wind turbines;<br />

• Route and design of access tracks;<br />

• Location and design of temporary borrow pits and temporary construction compounds;<br />

• Location and size of wind monitoring masts;<br />

• Land management changes; and<br />

• Layout and number of wind turbines.<br />

3.4.9 The importance of good design has been included as an integral part of the proposed wind<br />

farm so as to avoid, minimise and, where necessary, compensate <strong>for</strong> potential adverse<br />

effects. The specific landscape and visual design criteria used to in<strong>for</strong>m the site design<br />

process <strong>for</strong> the proposed wind farm were as follows;<br />

• To establish a simple and compact <strong>for</strong>m which has a unified appearance.<br />

• Avoidance of outlier turbines and visual stacking.<br />

• Relationship of the wind farm to the character, scale, pattern and composition of the<br />

landscape.<br />

• Potential conflicts with sense of remoteness.<br />

• Relationship of turbines with backdrop and horizon.<br />

• Relationship with existing wind farm turbine size, scale and layout.<br />

3.4.10 In addition to turbine layout the location of wind farm infrastructure was also considered in the<br />

design process.<br />

3.4.11 The integration of the wind farm in a landscape of commercial <strong>for</strong>estry and the potential <strong>for</strong><br />

enhancement of the conifer plantations through diversification of species and structure <strong>for</strong>ms<br />

part of the ongoing, long term management of the <strong>for</strong>estry by the FCS.<br />

3.5 Design Evolution<br />

Introduction<br />

3.5.1 Following selection of the site, the layout of the proposed wind farm evolved over a period of<br />

around two years. The design of the layout was led by all criteria as set out in this Chapter,<br />

taking into account the characteristics of the site and surrounding area, the predicted<br />

environmental impacts emerging from the technical assessments being undertaken, and the<br />

technical requirements of turbine efficiency and output maximisation.<br />

3.5.2 Although a number of different changes were made to the turbine layout, the layout evolved<br />

over three main iterations which have been referred to in the remainder of this chapter as:<br />

1. Initial Design – a 77 turbine layout including the <strong>for</strong>estry block south of the reservoir;<br />

Carron Valley Wind Farm<br />

2. Intermediate Design – a 24 and then a 2 x 16 turbine layout;<br />

3. Final Design – a 15 turbine layout.<br />

Initial Design<br />

3.5.3 The bulk site screening work and feasibility carried out by PfR identified an initial design<br />

layout <strong>for</strong> the site. A feasibility study was then carried out to consider the potential of the site<br />

in more detail. The initial design layout and feasibility study identified that the site could<br />

accommodate up to 77 turbines of up to 3 MW as shown on Figure 3.5.<br />

3.5.4 At this stage in the project the site boundary encompassed the majority of the Carron Valley<br />

Forest, including both <strong>for</strong>est blocks north and south of the Carron Valley Reservoir.<br />

3.5.5 In<strong>for</strong>mation to in<strong>for</strong>m the feasibility study was gathered through a combination of desk based<br />

study, including in<strong>for</strong>mation from FCS records, and consultation. Feasibility work included:<br />

• Collection of wind speed data in<strong>for</strong>mation from the NOABL UK Wind Speed Database<br />

and through an assessment carried out by SgurrEnergy and preliminary wind analysis;<br />

• Desk based review of site constraints including ecology, ornithology and cultural<br />

heritage and associated consultation with the Forestry Commission Scotland;<br />

• Consideration of likely grid connection options and arrangements;<br />

• Preliminary turbine delivery route assessment;<br />

• Provision of an indicative track and infrastructure layout;<br />

• Consideration of relevant planning policy;<br />

• Preliminary consultation with Ofcom to identify fixed and microwave links and more<br />

detailed consultation with Cable and Wireless, Arqiva, Orange and JRC;<br />

• Initial consultation with the Ministry of Defence (MOD), Civil Aviation Authority (CAA),<br />

NATS En-Route Limited (NERL) mapping tool and BAA/Glasgow Airport. An initial<br />

Aviation Impact Assessment was also carried out;<br />

• Preliminary noise modelling and an initial ETSU-R-97 assessment;<br />

• Preliminary consultation with the following infrastructure operators: Scottish Power,<br />

Scotland Gas Networks and the Health and Safety Executive;<br />

• A preliminary Zone of Theoretical Visibility (ZTV) to 35 km.<br />

3.5.6 A number of constraints and appropriate separation distances were also considered within<br />

the initial design including from watercourses to avoid or minimise physical interface,<br />

residential properties to protect amenity, ancient woodland, roads and public rights of way /<br />

bridleways, infrastructure including pipelines and power lines, and radar visibility and<br />

communications links.<br />

3.5.7 Only minor changes to the initial design turbine locations were made following the feasibility<br />

study. The study concluded that the site could accommodate up to 77 turbines, fifteen of<br />

which were within the Cairnoch Hill Site, however the study also identified a number of key<br />

risks to the layout at this stage of the design evolution process as follows:<br />

• Aviation - Consultation with NERL identified that turbines in areas to the north and<br />

south of the site are ‘likely to interfere with NATS radar systems’.<br />

Carron Valley Wind Farm<br />

• Cultural Heritage/Archaeology – Two Scheduled Monuments are located within the<br />

site.<br />

• Ecology – Proposed development may impact on nearby Endrick Water Special Area<br />

of Conservation (SAC) / Site of Special Scientific Interest (SSSI).<br />

• Landscape / Visual – A large number of turbines are likely to give rise to visual<br />

impacts.<br />

• Noise – Cumulative noise impact of two adjacent wind farms are likely to require<br />

removal of turbines.<br />

• Ornithology – Bird nests identified within site, turbines should be relocated to reduce<br />

the potential impact.<br />

• Scanning Telemetry – Link identified within proximity to turbine locations.<br />

• Shadow Flicker – There are properties identified within the zone of shadow flicker.<br />

3.5.8 The work in DP1, as described in Section 3.3 above, included risk management of areas that<br />

could potentially stop development on the Carron Valley site.<br />

3.5.9 One of these areas was aviation risk, and initially the Ministry of Defence objected to the 77<br />

turbines due to unacceptable impact on their Met Office radar at Holehead. The main<br />

objection was due to the proximity of the turbine to the radar, the number of turbines, and the<br />

visibility of the turbines to the radar main beam. This resulted in the removal of turbines<br />

closest to the radar installation, and within direct Line of Sight of the main beam.<br />

3.5.10 Some turbines were also having an impact on Glasgow PSR and Lowther Hill radar,<br />

controlled by BAA and NATS. Turbines within Line of Sight of these radar installations were<br />

removed.<br />

3.5.11 Following this, a layout of 37 turbines was deemed feasible which concentrated on the areas<br />

around the reservoir, thereby avoiding areas where turbines would be detected by military<br />

and civilian radar systems.<br />

3.5.12 A further Landscape and Visual Feasibility Study was undertaken in December 2010 based<br />

on this layout. This concluded that further detailed design should focus only on the Cairnoch<br />

Hill site to the north of the reservoir. The main reason <strong>for</strong> this conclusion was that the wind<br />

farm could be viewed as two wind farms when travelling on the B818 road, and from key<br />

viewpoints. The reservoir acts as a natural divider between turbines north and south of it, and<br />

taking into account the location of existing operational and consented wind farms, the location<br />

of Cairnoch Hill was chosen in May 2011 as most suitable within the land holding and<br />

identified constraints.<br />

3.5.13 The final exercise in DP1 was there<strong>for</strong>e to produce a constraints plan focused on the<br />

Cairnoch Hill block.<br />

Intermediate Design<br />

Overview<br />

3.5.14 The above described process enabled the team to deal with most of the outstanding risks,<br />

including designing a layout that could be made acceptable to radar operators.<br />

Constraints Plan and Developable Area<br />

3.5.15 Focusing only on Cairnoch Hill, an updated constraints plan was prepared showing the<br />

location and necessary buffers of the known physical and environmental constraints present<br />

on the site and its environs. The constraints were identified and refined throughout the EIA<br />

process, through consultation with stakeholders, desk-based research, relevant guidance,<br />

site visits and survey works (including Extended Phase 1 Habitat Surveys, ornithology<br />

surveys and cultural heritage site walkovers).<br />

3.5.16 Constraints were mapped using a GIS and buffer zones created around known constraining<br />

features. Constraints that were applied to the proposed development site as identified in<br />

3.5.17 In addition to the constraints identified in Table 3.1, RPS consulted with communications links<br />

operators through Ofcom. No fixed links were identified within or in the vicinity of the site.<br />

3.5.18 The constraints plan was then used to determine the site area potentially suitable <strong>for</strong><br />

development, referred to as the ‘Developable Area’. The Developable Area was considered<br />

to be land which may be suitable to locate turbines and other wind farm components, and is<br />

shown in Figure 3.2.<br />

Design Workshop<br />

3.5.19 A theoretical layout of 24 turbines was initially prepared based only on physical spacing<br />

within the developable area using the requisite turbine separation distances (Figure 3.5) and<br />

a Zone of Theoretical Visibility (ZTV) model was run on this layout to identify visibility. From<br />

an initial review of landscape and visual constraints, and particularly the potential full visibility<br />

of turbines from the Wallace Monument and Stirling Castle, the initial 24 turbine layout was<br />

reduced to a 16 turbine layout (Figure 3.5) which became the starting point <strong>for</strong> the design<br />

workshop held on 1 September 2011.<br />

3.5.20 The 16 turbine layout was then refined within the workshop through the application of several<br />

key design principles, including:<br />

• Landscape and Visual – Zone of Theoretical Visibility (ZTV) models and wirelines from<br />

key visual receptors were run to assess and then modify the turbine layout to reduce<br />

impacts in terms of overall visibility, particularly from key sensitive viewpoints such as<br />

Stirling Castle, as well as turbine overlap and clustering. This process resulted in a<br />

number of iterations to the layout. Figure 3.3 shows comparative wirelines from the<br />

key viewpoints used during the design process. Relevant visual issues associated<br />

with cultural heritage (including the setting of Sir John de Graham’s Castle Scheduled<br />

Monument) and recreation were also considered as part of this assessment (refer to<br />

Chapter 9: Landscape and Visual Impact Assessment, Chapter 15: Socioeconomics,<br />

Tourism, Recreation, and Land Use and Chapter 10: Cultural Heritage and<br />

Archaeology);<br />

• Peat – The layout was designed and revised to avoid areas of deeper peat (Figure 3.4)<br />

identified on the site through peat probing (refer to Chapter 13: Hydrology,<br />

Hydrogeology and Ground Conditions);<br />

• Site Infrastructure – Maximising the use of existing tracks within the site boundary and<br />

minimising new watercourse crossings (refer to Chapter 13: Hydrology, Hydrogeology<br />

and Ground Conditions);<br />

• Forestry – FCS preferred turbine locations were considered in line with the emerging<br />

amendment to the FDP. This process enabled the creation of a layout sensitive to the<br />

requirements of ongoing <strong>for</strong>estry operations and responding to the FDP in relation to<br />

minimising unnecessary removal of coupes or compromising the wind firmness of<br />

remaining <strong>for</strong>est blocks.<br />

• Noise – The noise contour and noise modelling was rerun following each design<br />

iteration in order to identify any significant change to the contour within which each<br />

potential Noise Sensitive Receptor (NSR) was predicted to fall (refer to Chapter 8:<br />

Noise and Figure 8.1).<br />

Carron Valley Wind Farm<br />

3.5.21 Following review of all site constraints and other issues identified above an optimum layout of<br />

16 turbines was identified as the Intermediate Design (Figure 3.5). A number of further<br />

assessments were then carried out on this layout:<br />

• A shadow flicker plan was prepared to ensure no inhabited properties fell within the<br />

zone of potential shadow flicker (refer to Chapter 14: Shadow Flicker).<br />

• An assessment of the wind resource was undertaken.<br />

• The MOD was re-consulted on the Intermediate Design layout and confirmed no<br />

objection.<br />

3.5.22 A design was developed at this stage <strong>for</strong> the access tracks and supporting wind farm<br />

infrastructure, including the location of a permanent anemometry mast. These features were<br />

similarly sited and routed to avoid environmental constraints as well as optimising the use of<br />

slope <strong>for</strong> constructability and safety of construction traffic within the site.<br />

3.5.23 Access to the site was in<strong>for</strong>med by a number of factors including sufficient turning radii and<br />

utilisation of existing tracks. In designing the access tracks the following objectives were<br />

taken into account:<br />

• Minimising the number of watercourse crossings required;<br />

• Avoiding environmental constraints identified during the early design and EIA process;<br />

• Maximising the use of existing access tracks;<br />

• Minimising ground disturbance by using the shortest route possible; and<br />

• Ensuring gradients are suitable <strong>for</strong> vehicular access.<br />

3.5.24 The route and alignment of the new access tracks has also taken land stability and<br />

topography into account.<br />

3.5.25 A buffer of 77.5 m was also put in place around all infrastructure, including the provision of<br />

turbine keyholes, to indicate removal of <strong>for</strong>estry required specifically <strong>for</strong> the wind farm. This<br />

buffer reflects the requirements of the Natural England Guidance (Natural England, 2009) <strong>for</strong><br />

protection of bats, which requires an offset of 50 m between the <strong>for</strong>est edge and the blade<br />

tip.<br />

Final Design<br />

3.5.26 After further EIA assessment, consultation with public and statutory/non-statutory bodies, and<br />

consideration of the <strong>for</strong>mal Scoping Opinion received from Stirling Council (Appendix 2.2), it<br />

was considered that a further iteration to the design was required. This related in particular to<br />

concerns raised by Historic Scotland regarding the potential impact on turbines on the setting<br />

on the Sir John de Graham’s Castle Scheduled Monument identified within their <strong>for</strong>mal<br />

Scoping Response (refer to Chapter 10: Cultural Heritage and Archaeology).<br />

3.5.27 Following subsequent consultation with Historic Scotland a further design workshop was held<br />

on the 20 February 2012 to reconfigure the proposed turbine locations in light of Historic<br />

Scotland’s comments, with a view to reducing the potential effects on the setting on the Sir<br />

John de Graham’s Castle Scheduled Monument. As a result of concerns raised by Historic<br />

Scotland, two of the turbines in the Intermediate Design layout were removed, and the<br />

remaining 14 turbines were rearranged within the previously defined constraints and<br />

developable area to address the gap left.<br />

Carron Valley Wind Farm<br />

3.5.28 Through the redesign process using 14 turbines it was clear that the developable area could<br />

accommodate a fifteenth turbine whilst still achieving the design objective of maximising the<br />

separation distance between the castle and the turbines and avoiding, as far as reasonably<br />

practicable, the positioning of turbines in the field of view looking down the Carron Valley, that<br />

being the view that most aids interpretation of why the castle was originally sited in this<br />

location.<br />

3.5.29 Using the resultant 15 turbine layout, wirelines from key visual receptors were rerun (Figure<br />

3.3) to reassess and make minor alterations to turbine positioning to further reduce impacts<br />

on the setting of the Scheduled Monument, and to confirm that there was no substantial<br />

change to the likely visual impacts predicted from the other sensitive receptors considered<br />

previously, and the viewpoint locations now known to be included within the LVIA<br />

assessment.<br />

3.5.30 In addition the noise contour was rerun and noise modelling was undertaken to determine the<br />

predicted noise levels at each NSR, baseline data was used to set the day and night time<br />

noise limits in accordance with ETSU-R-97 methodology, and to confirm that predicted noise<br />

levels fall within those limits (refer to Chapter 8: Noise and Figure 8.1).<br />

3.5.31 A further assessment of shadow flicker and wind resource was carried out as well as initial<br />

noise modelling to ensure that the revised layout did not substantially change the predicted<br />

noise levels at nearby noise sensitive receptors.<br />

3.5.32 This process confirmed that a 15 turbines layout could be brought <strong>for</strong>ward to respond to the<br />

comments raised by Historic Scotland without materially affecting the significance of impacts<br />

on other environmental disciplines. This 15 turbine layout is shown on Figure 3.6.<br />

3.5.33 On this basis, the infrastructure design was revised, including relocating the permanent<br />

anemometry mast, and the red line boundary was confirmed to reflect the minimum land take<br />

necessary to accommodate all infrastructure <strong>for</strong> the proposed wind farm.<br />

3.5.34 Further consultation on the new proposed site layout was then carried out with Historic<br />

Scotland to present and explain the changes made and seek views on the likely acceptability<br />

of the proposal as revised. The MOD was also re-consulted on the amended layout and<br />

reconfirmed no objection.<br />

3.5.35 This final design was confirmed as the basis of the application and EIA and the design frozen<br />

accordingly. The revised turbine locations were then provided to FCS and the proposed<br />

amendment to the FDP was updated to align with the revised turbine layout.<br />

Carron Valley Wind Farm<br />

4 Description of the Proposed Development<br />

4.1 Introduction<br />

Overview<br />

4.1.1 This chapter describes the proposed Carron Valley Wind Farm including the main<br />

development components, associated infrastructure and details of construction methods and<br />

timescales.<br />

4.1.2 It also provides detailed consideration of the <strong>for</strong>est environment at Carron Valley and initial<br />

consideration of the likely <strong>for</strong>est related impacts associated with the wind farm proposal as<br />

described in this chapter.<br />

4.1.3 As stated in Chapter 1: Introduction, key objective of the proposed wind farm is to generate<br />

approximately 98.55 gigawatt-hours (GWh) of renewable energy, thereby preventing<br />

approximately 42,376 tonnes of CO 2 being emitted each year and producing enough energy<br />

to supply up to of up to 22,081 average households in Britain.<br />

Main Scheme Components<br />

4.1.4 The layout of the proposed wind farm is shown on Figure 1.2. The proposed wind farm<br />

includes the following key components:<br />

• 15 variable pitch (three-bladed) wind turbines each to a maximum of 126 m to tip (see<br />

Figure 4.1);<br />

• 15 circular rein<strong>for</strong>ced concrete gravity foundations of approximate 21 m diameter<br />

(typically containing approximately 727 m 3 structural concrete and 65 tonnes of high<br />

yield steel rein<strong>for</strong>cement) (see Figure 4.2);<br />

• Crane hard-standing areas adjacent to each wind turbine with approximate dimensions<br />

of 45 m x 25 m and a 2 m wide granular path to the turbine base (see Figure 4.3);<br />

• A total of 9.4 km of 5 m wide access tracks from the site entrance to each turbine<br />

location and other wind farm components. The internal tracks required <strong>for</strong> construction<br />

of the wind farm will be in existence as FCS <strong>for</strong>est roads in advance of construction<br />

commencement, and will be upgraded to meet the loading requirements of<br />

construction vehicles. This will result in 7.5 km of upgraded <strong>for</strong>estry track and 1.9 km<br />

of new track <strong>for</strong> construction of the wind farm (see Figure 4.4);<br />

• A temporary hard-cored construction compound (approximately 50 m x 50 m to locate<br />

a refuelling area, materials storage, batching facility and welfare facilities) (see Figure<br />

4.5);<br />

• A single-storey, pitched roof control building comprising of a control room, switch room<br />

and metering room (typical dimensions are 5 m x 10 m x 5.5 m) (see Figure 4.6);<br />

• One permanent anemometry mast at a height equivalent to the maximum hub height<br />

depending on the selected turbine (see Section 4.3), there<strong>for</strong>e of up to 85 m high (see<br />

Figure 4.7);<br />

Description of the Proposed Development


Carron Valley Wind Farm<br />

• Underground electrical and SCADA 1 cabling in trenches linking each wind turbine with<br />

the site control building (see Figure 4.8);<br />

• 7 m wide crossing points along the access tracks at typically 250 m intervals and 30 m<br />

long passing places at a distance of the order of 500 m apart (see Figure 4.9);<br />

• Three borrow pits to provide material <strong>for</strong> construction aggregate, with the potential to<br />

provide an estimated 67,500 m 3 of material, representing about twice the estimate of<br />

aggregate volume required (see Appendix 13.1); and<br />

• Upgrading a total of six watercourse crossings (see Appendix 13.3).<br />

4.1.5 The actual footprint of each key development component is identified in Table 4.1 below.<br />

4.2 Site Description and Context<br />

Site Context<br />

4.2.1 The site is part of Cairnoch Hill, which <strong>for</strong>ms the northern block of the Carron Valley Forest.<br />

It is located within Stirlingshire, approximately 10 km north-west of Cumbernauld and<br />

approximately 7 km north of Kilsyth, Central Scotland at approximate grid reference NS 6970<br />

8550. The location of the site is shown on Figure 1.1.<br />

4.2.2 The elevation of the site varies from approximately 225 m AOD to approximately 413 m AOD<br />

at its peak. Cairnoch Hill comprises approximately 505 ha of productive plantation woodland.<br />

The area within the proposed wind farm application boundary comprises approximately<br />

340.6 ha.<br />

4.2.3 Whilst the majority of the site consists of plantation woodland there is also an open hill area<br />

which has not been af<strong>for</strong>ested and other open areas within the <strong>for</strong>est awaiting restocking post<br />

tree removal during harvesting operations.<br />

Carron Valley Wind Farm<br />

4.2.4 The southern boundary of the site is <strong>for</strong>med by the B818 and then the Carron Valley<br />

Reservoir. The remainder of Carron Valley Forest is located to the south of the reservoir and<br />

provides a well used recreational resource <strong>for</strong> walkers, mountain bikers and horse riders, and<br />

incorporates hills at Meikle Bin (570 m AOD), Little Bin (443 m AOD), and Drumbuoy (393 m<br />

AOD).<br />

4.2.5 A number of properties lie along the B818 and further isolated properties are situated within<br />

the vicinity of the site.<br />

4.2.6 Cairnoch Hill is drained by <strong>for</strong>estry drainage systems and by a number of small unnamed<br />

watercourses. The southern hill slopes drain towards Carron Valley Reservoir. Towards the<br />

north-east small watercourses discharge into the Earl’s Burn which confluences with the<br />

River Carron downstream of Carron Valley Reservoir. The River Carron discharges into the<br />

Firth of Forth near Grangemouth. The north-western hill slopes drain via an unnamed burn to<br />

the Endrick Water. The Endrick Water flows west and discharges into Loch Lomond near<br />

Balmaha.<br />

Designations<br />

4.2.7 The site itself falls is not the subject of any international or national designations. It lies within<br />

an Area of Great Landscape Value (AGLV) and is identified as an Area of Significant<br />

Protection within Supplementary Planning Guidance (SPG) produced by Stirling Council<br />

(Stirling Council, 2011).<br />

4.2.8 There are four Sites of Special Scientific Interest (SSSIs) within 5 km of the site: Endrick<br />

Water, Double Craigs, Denny Muir and Carron Glen. Endrick Water SSSI is the closest at<br />

approximately 2.2 km to the west of the site boundary and is also designated a Special Area<br />

of Conservation (SAC).<br />

4.2.9 There are several historic environment assets of national importance within 10 km of the site.<br />

The remains of Sir John de Graham’s Castle (Scheduled Monument) are located within the<br />

<strong>for</strong>est block to the west of the proposed site boundary.<br />

4.2.10 Designations in the vicinity of the proposed site are shown on Figure 4.10 (within 10 km) and<br />

Figure 4.11 (within 35 km).<br />

History of the Forest<br />

4.2.11 Cairnoch Hill Plantations are managed by Forestry Commission Scotland (FCS). The<br />

Forestry Commission was set up in 1919 by the UK Government to ensure a timber reserve<br />

following the First World War. The UK had a very small percentage of land under woodland<br />

management and the Forestry Commission was tasked with increasing the volume of<br />

available timber to the UK and reducing its reliance on overseas imports.<br />

4.2.12 This policy was the main driving <strong>for</strong>ce <strong>for</strong> UK Forest Policy <strong>for</strong> the next fifty years. The<br />

plantations at Cairnoch Hill were planted to comply with the demands of this policy. The hill<br />

was very much open ground up to the early 1950’s. The OS plans from 1952 (Stirlingshire<br />

1:10,560) show Carron Valley Reservoir but only scattered plantings on the hill. By 1958 the<br />

OS plan (Stirlingshire 1:10,560) <strong>for</strong> the site shows plantations to the east and west and a<br />

central open area. This area was planted up in the 1960’s to complete the plantations found<br />

there today.<br />

4.2.13 The early plantations followed the pattern of commercial <strong>for</strong>estry planting regionally with the<br />

vast majority of trees planted being coniferous and in particular Sitka Spruce (Picea<br />

sitchensis). Sitka spruce is a fast growing tree from the western coast of the United States<br />

and provides timber of reasonable quality. It is also very adaptable to the site conditions of<br />

those presented at Cairnoch Hill.<br />

4.2.14 The Forestry Commission (FC) managed its plantations using, in the majority, economic<br />

rotations based around the yield class system as described in the Forest Mensuration<br />

Handbook (Forest Research, 2006). This considered potential yield of the crop with a rotation<br />

length refined by consideration of the wind firmness of the crop.<br />

4.2.15 The latest management strategy <strong>for</strong> FC woodlands is based on this system but refined further<br />

to take account of <strong>for</strong>est restructuring and reduction in visual impacts caused by large scale<br />

<strong>for</strong>est felling. Forest managers create a Forest Design Plan (FDP) from the crop in<strong>for</strong>mation<br />

and this becomes the operational plan <strong>for</strong> the next <strong>for</strong>est rotation. The FDP is a ten-year<br />

plan, reviewed at five-year intervals.<br />

4.2.16 The initial plantations were set out in a very structured and set pattern with <strong>for</strong>est blocks<br />

being straight edged where contours or existing features were not present. Much of the site is<br />

approaching its second rotation and changes are being made to the structure of the size,<br />

shape and species mix of the <strong>for</strong>est compartments. Where possible, <strong>for</strong>est thinnings have<br />

been harvested as prescribed in Forestry Commission Booklet 34, Forest Management<br />

Tables (Forestry Commission, 1971). However where the likelihood of wind blow has been<br />

assessed as high then a ‘No Thin’ approach has been taken as the management approach.<br />

4.2.17 A Forestry Devolution Review was carried out in 2002 and resulted in the Forestry<br />

Commission devolving into the individual countries of the UK. Scottish <strong>for</strong>ests came under<br />

the responsibilities of the Scottish Ministers and Carron Valley became part of the Scottish<br />

Lowland Forest District.<br />

Current Forest Strategy<br />

4.2.18 The Scottish Forestry Strategy (SFS) was published in October 2006. Implementation of the<br />

Strategy has been focused on delivering <strong>for</strong>estry benefits to Scotland helping to achieve the<br />

Scottish Government’s wider policies to contribute towards its National Outcomes.<br />

4.2.19 The strategy also recognises the changing role and crosscutting nature of <strong>for</strong>estry and as<br />

such is organised around seven key themes which include: Climate Change, Timber,<br />

Community Development, Environmental Quality, Business Development, Access & Health<br />

and Biodiversity. This recognition of the wider importance of <strong>for</strong>ests has greatly influenced<br />

the way in which woodlands are now managed, and particularly the decision making<br />

processes involved. There is also the Strategic Plan <strong>for</strong> the National Forest Estate which<br />

directs the implementation of the SFS on the national <strong>for</strong>est estate over five years, from 2009<br />

to 2013. It provides context and direction <strong>for</strong> ten local district strategic plans.<br />

4.2.20 The Scottish Lowlands Forest District Strategic Plan 2009-2013 defines how the SFS will be<br />

implemented at a local level and accounts <strong>for</strong> local priorities and context. It also provides<br />

direction <strong>for</strong> implementing a repositioning policy that will ensure that the nature and<br />

distribution of the national <strong>for</strong>est estate better reflects its role and purpose. This strategic<br />

plan recognises the importance of <strong>for</strong>estry in the natural environment and the contribution it<br />

makes to the local communities. Many of the <strong>for</strong>ests in this region are near local<br />

communities, and Carron Valley and Cairnoch Hill are visited by recreational day visitors on a<br />

regular basis.<br />

Carron Valley Wind Farm<br />

4.2.21 The strategy also recognises that the role of <strong>for</strong>ests should be to develop business<br />

opportunities and provide employment not only inside <strong>for</strong>estry but the industries that develop<br />

around it.<br />

4.2.22 Climate change and renewable energy production is a key theme that is developed in the<br />

strategy. The potential <strong>for</strong> wind farm development and wood fuel energy projects will reduce<br />

the impacts of carbon emissions. The development of wind farms in the district are clearly<br />

identified in the Renewable Energy section of Key Theme One: Climate Change in which it<br />

states:<br />

‘Scot Low 1.01 - Maximise the potential <strong>for</strong> windfarms and other renewable energy<br />

projects with regard to landscape, biodiversity, public access, community and economic<br />

values. We have three active sites with two pending at Whitelee and Murdostoun, and<br />

working with partnership <strong>for</strong> renewables (PfR) on 20 other sites.’<br />

4.2.23 This is combined with a desire to research the use of coppice and Short Rotation Forestry<br />

(SRF) to provide a sustainable wood fuel resource. Cairnoch Hill and the short rotation<br />

periods provided by the <strong>for</strong>est provides a perfect site <strong>for</strong> the development of areas managed<br />

in this way.<br />

4.2.24 Cairnoch Hill has presented various constraints to <strong>for</strong>est development, these are mainly a<br />

combination of soils and exposure. The wind firmness of the site has been a particular<br />

challenge to management of the <strong>for</strong>est. Once the trees have established and reached a<br />

reasonable height they have been subject to wind blow. Up to January 2012 approximately<br />

71 hectares (ha) were surveyed areas of wind blow requiring clearance, and in January 2012<br />

a major storm hit the region and a further 39 ha was affected by wind blow. The short period<br />

in which the <strong>for</strong>est was planted has resulted in a period where large areas are now being<br />

restocked as part of the rotational cycle and further areas that were to be retained to reduce<br />

the visual impact of <strong>for</strong>est felling now have to be cleared due to wind blow.<br />

4.2.25 Much of the current <strong>for</strong>est management of Cairnoch Hill is driven by the crop conditions and<br />

this current period of felling and restocking is related to the age and height of the trees. Their<br />

wind firmness, to a certain extent, is also dictating the management of the <strong>for</strong>est and will<br />

continue to do so over the coming decades.<br />

Forest Design Plan<br />

4.2.26 As noted above, the FCS produces a FDP <strong>for</strong> each of its <strong>for</strong>est areas. The FDP covers the<br />

<strong>for</strong>est rotation period , is approved at a ten-year basis and is reviewed at five-year intervals.<br />

It details felling and restocking patterns during the period, and is based on the current<br />

principles of management produced in the Lowland District Strategy document. The current<br />

plan and restocked compartment shapes and sizes show the move towards reduced felling<br />

coupe sizes and less hard boundaries to the compartments. All FDP’s con<strong>for</strong>m to the United<br />

Kingdom Woodland Assurance Standard (UKWAS).<br />

4.2.27 The March 2012 amendment to the FDP (see Appendix 4.1) incorporates the January 2012<br />

wind blow damage into its overall felling programme. The amendment is a result of the<br />

reasons described above and due to the wind farm proposal. The FDP amendment was<br />

approved by FCS Conservancy on 12 June 2012.<br />

4.2.28 The plan also shows proposed <strong>for</strong>est roads to be constructed to aid extraction and access to<br />

the <strong>for</strong>est.<br />

4.2.29 The FDP is a dynamic plan that can be altered and adjusted through its period as required. It<br />

is an important planning tool but is not definitive as it is dealing with a growing medium that is<br />

subject to climatic and economic impacts.<br />

4.2.30 An important influencing factor that could in the future have a major influence on <strong>for</strong>est crops<br />

on Cairnoch Hill and other similar <strong>for</strong>ests is that of tree pests and diseases. Recent years<br />

have seen greater concerns about the impacts of diseases such as Phytophthora ramorum<br />

on <strong>for</strong>est tree species. This fungal pathogen has been responsible <strong>for</strong> large areas of<br />

Japanese larch being felled in many other parts of the UK and could spread to the area in the<br />

future. Dothistroma Needle Blight (DNB) previously known as Red Band Needle Blight is also<br />

now becoming of great concern to <strong>for</strong>est mangers as it was originally thought to only affect<br />

Corsican Pine, but has now been known to affect Scots Pine.<br />

4.2.31 The restocking plan shows a much greater proportion of Larch and Scots Pine being used<br />

within Cairnoch Hill than was previously the case. Changes in species from the previously<br />

preferred monoculture of Sitka spruce has followed the Forestry Commission policy to create<br />

greater species diversity and to improve the landscape, visual quality and to an extent crop<br />

stability within individual <strong>for</strong>ests.<br />

4.2.32 Appendix 4.1 presents the approved amendment to the FDP (March 2012) showing proposed<br />

felling, restocking and compensatory planting. This represents the “with-development”<br />

scenario incorporating the infrastructure footprint <strong>for</strong> the proposed wind farm including turbine<br />

positions, access roads, borrow pits and passing places, and the extent of recent and<br />

potential felling at Cairnoch Hill. The loss of <strong>for</strong>est due to the wind farm footprint is a total of<br />

33.52 ha (FCS figure) however only 13 ha are permanently lost to <strong>for</strong>estry, the rest is lost<br />

only <strong>for</strong> the period of the wind farm and will be available to be re<strong>for</strong>ested directly following decommissioning.<br />

4.2.33 FCS has identified approximately 275 ha within the <strong>for</strong>est as areas of potential Short Rotation<br />

Forestry (SRF) or Early Felling (EF). SRF is defined as single or multi-stemmed trees of fast<br />

growing species grown on a reduced rotation length primarily <strong>for</strong> the production of biomass.<br />

EF means that a non-mature coupe will be felled within five years of the start of operation of<br />

the wind farm, and subsequently replanted.<br />

4.2.34 FCS has guaranteed PfR 20 % of this SRF/EF area to improve wind flow and energy capture.<br />

In the event that the wind farm is consented, FCS will submit a FDP amendment which<br />

includes the wind farm footprint and agreed SRF/EF areas shown in Appendix 4.2. It should<br />

be noted that this area is currently indicative only as, <strong>for</strong> instance, further wind blow may<br />

cause another FDP amendment and consequent re-evaluation of the potential SRF/EF areas.<br />

The plans presented in Appendix 4.2 are there<strong>for</strong>e included within this <strong>ES</strong> <strong>for</strong> in<strong>for</strong>mation only<br />

and do not <strong>for</strong>m part of the proposed development as assessed.<br />

4.3 Energy Generation and Anemometry<br />

Candidate Wind Turbine Model<br />

4.3.1 The proposed wind farm will consist of 15 variable pitch (three bladed) wind turbines with a<br />

maximum tip height of 126 m. The final choice of turbine will be dependent on the wind<br />

analysis, turbine economics and available technology at the time of construction. As the<br />

turbine choice has not been finalised, assumed maximum dimensions have been used within<br />

the <strong>ES</strong> to ensure that a reasonable worst case scenario is assessed. It is anticipated that the<br />

turbines will have a maximum 85 m hub height and a maximum 45 m blade radius, however<br />

the turbine tip height will not exceed 126 m. Where directly relevant to the technical<br />

assessments in this <strong>ES</strong>, each chapter states the assumed turbine parameters used.<br />

4.3.2 The maximum rating of each turbine will be 3 MW of renewable energy, providing a total<br />

installed capacity of up to 45 MW.<br />

4.3.3 The candidate turbines that have been investigated all comprise of the following main<br />

components: rotor blades (three), nacelle (containing gearbox and generator), tower (in three<br />

sections), base ring, blade hub and foundation. Table 4.2 outlines the assumed technical<br />

parameters of the turbines and Figure 4.1 illustrates the dimensions of the turbine.<br />

4.3.4 The turbine towers will be of tapering tubular steel construction and the blades will be made<br />

of fibreglass with lightning protection, to protect the entire turbine. Turbines will be finished in<br />

a pale grey/off-white colour with a semi-matt finish, subject to agreement with Stirling Council<br />

and other consultees.<br />

4.3.5 Depending on the eventual model selected, turbines will generate electricity in wind speeds<br />

of between 2 – 4 m/s and 25 m/s and will be computer controlled to ensure that they face<br />

directly into the wind <strong>for</strong> optimum efficiency. At wind speeds that exceed 25 m/s the turbines<br />

will shut down automatically <strong>for</strong> self-protection.<br />

4.3.6 Wind turbine towers, blades and nacelles are likely to be transported to the site via trailers<br />

with self-steering rear axles. The tower sections and other turbine components will be stored<br />

either at a designated lay down area or at each turbine hard standing until turbine erection<br />

commences.<br />

4.3.7 There will a trans<strong>for</strong>mer located outside each turbine base.<br />

4.3.8 In line with a requirement <strong>for</strong> aviation lighting stipulated by Defence Estates (see Chapter 2:<br />

The Environmental Impact Assessment and Scoping Process, Table 2.1), the turbines will be<br />

fitted with an appropriate <strong>for</strong>m of lighting which is proposed to be infrared subject to<br />

agreement with Defence Estates and other relevant consultees.<br />

4.3.9 The proposed turbine locations have been the subject of an extensive design iteration<br />

process, taking into account visual, environmental, and ground stability constraints as well as<br />

consultee and public feedback, as described in Chapter 3: Design Evolution. However, up to<br />

a maximum of 50 m radius of micrositing flexibility around each turbine is requested by the<br />

applicant to allow further on site constraints that may be identified during intrusive ground<br />

investigations to be avoided. All micrositing will be agreed in advance with Stirling Council<br />

and Scottish Natural Heritage (SNH).<br />

Anemometry Mast<br />

4.3.10 An anemometry (met) mast is proposed to be in place <strong>for</strong> the life of the wind farm. This will<br />

have a maximum height of 85 m (the maximum hub height of the selected turbine model).<br />

This will be a free standing lattice tower mast feeding in<strong>for</strong>mation to the wind farm control<br />

centre.<br />

4.4 Electrical Connection<br />

Off-site Grid Connection<br />

4.4.1 The proposed wind farm will require a connection to the electrical transmission network. The<br />

connection is likely to be made at Bonnybridge substation some 15 km east of the site, in the<br />

<strong>for</strong>m of two underground cables at 33 kilovolt (kV) each. PfR is in the process of<br />

investigating this further and will seek an Offer of Connection from Scottish Power Energy<br />

Networks at the appropriate time.<br />

4.4.2 The grid connection <strong>for</strong> the proposed wind farm will be the subject of a separate application<br />

under Section 37 of the Electricity Act 1989 and is there<strong>for</strong>e not described in further detail<br />

within this <strong>ES</strong>.<br />

Control Building<br />

4.4.3 Figure 1.2 shows the location of the control building and Figure 4.6 illustrates its technical<br />

parameters.<br />

4.4.4 The single storey control building will have a pitched slate (or slate substitute) roof. The<br />

building will be finished in a render appropriate to the surrounding area, to be agreed in<br />

advance with Stirling Council.<br />

4.4.5 The control building compound will be approximately 10 m x 5 m x 5.5 m high. The control<br />

building will comprise a control room, switch room and metering room. The SCADA system<br />

will allow turbine operations to be monitored and controlled from a central location, either on<br />

or off site to ensure early reporting and rectification of any faults that may occur. The control<br />

building will have fire and closed-circuit television (CCTV) detection systems.<br />

4.4.6 A small area of hardcore will be constructed outside the control building with parking <strong>for</strong> four<br />

vehicles. Any external signage will be agreed with Stirling Council. There will be no external<br />

illumination of the control building except <strong>for</strong> a small motion sensitive floodlight above the<br />

front entrance.<br />

Electrical Trans<strong>for</strong>mer and On Site Electrical Connections<br />

4.4.7 Electrical trans<strong>for</strong>mers will be located outside the turbine towers bases, linked to the on-site<br />

control building by underground cables. The cables will run parallel to access tracks, where<br />

practicable.<br />

4.5 Civils Works<br />

Wind Turbine Foundations<br />

4.5.1 Foundation construction design will be finalised at the detailed design and engineering stage.<br />

However, typical foundation designs <strong>for</strong> the candidate turbine are shown in Figure 4.2. Prior<br />

to construction, detailed intrusive ground investigations will be undertaken at each turbine<br />

location and, depending on the in<strong>for</strong>mation derived from these investigations, modifications<br />

may be made to the foundation designs.<br />

4.5.2 Construction of the turbine foundations will generally require excavation to expose suitable<br />

bearing strata. Depending on the terrain, the foundations will typically be constructed at a<br />

depth of approximately 3 m.<br />

4.5.3 The depth of the excavation will depend on the depth to the suitable bearing strata or pile<br />

cap. The sides will be ‘battered’ back to ensure that they remain stable during construction.<br />

Each foundation will require approximately 727 m 3 of structural concrete and 65 tonnes of<br />

high yield steel rein<strong>for</strong>cing.<br />

4.5.4 The excavated area will be back-filled with compacted layers of graded material from the<br />

original excavation, and capped with soil. Around the turbines, the finished surface will be<br />

capped with crushed aggregate to allow <strong>for</strong> safe personnel access around the base of the<br />

turbine.<br />

4.5.5 If appropriate, excavated material will be reused <strong>for</strong> access track construction, to supplement<br />

locally imported rock.<br />

4.5.6 A 5 m radius of hard standing will be laid around the turbine base, above the foundation, to<br />

allow <strong>for</strong> vehicular access to the turbine <strong>for</strong> maintenance purposes.<br />

Crane Pads<br />

4.5.7 A crane pad of approximately 45 m x 25 m will be required adjacent to each turbine base to<br />

accommodate the cranes required <strong>for</strong> construction and to provide a laydown area adjacent to<br />

each turbine location. Figure 4.3 illustrates a typical crane hard standing area. All hard<br />

standings will be <strong>for</strong>med with crushed rock over geotextile membranes.<br />

4.5.8 Hard standings will be sufficiently level to ensure the safe operation of the cranes. The<br />

turbine foundation will then be completed and backfilled as described above. The final detail<br />

of the crane hard standing will depend on the exact specification of the cranes selected by<br />

the contractor. A large crawler or wheeled/mobile crane will be required <strong>for</strong> turbine erection,<br />

with one smaller pilot crane assisting with the lift procedure.<br />

4.5.9 Crane hard standing areas will be allowed to naturally re-vegetate during operation of the<br />

wind farm.<br />

Site Access<br />

4.5.10 The existing access routes, in the <strong>for</strong>m of <strong>for</strong>est tracks and roads, would be upgraded within<br />

the site and new routes to each turbine location created where necessary. Typical cross<br />

sections across the proposed internal access tracks are illustrated in Figure 4.4.<br />

4.5.11 Access into the site itself would be taken via an upgraded junction from the B818, the outline<br />

layout design of which is presented in Appendix 7.1.<br />

4.5.12 The proposed site access is discussed in more detail in Chapter 11: Traffic and Transport.<br />

Description of the Proposed Development


Carron Valley Wind Farm<br />

Onsite Tracks<br />

4.5.13 FCS intends to install tracks to facilitate removal of wind blown <strong>for</strong>estry in advance of wind<br />

farm construction. To maximise integration between <strong>for</strong>estry activities and wind farm<br />

construction these tracks have been designed to follow the same alignment as would be<br />

utilised <strong>for</strong> the construction process following upgrade. There will also be some new access<br />

track construction, <strong>for</strong> example spurs between the main internal loop and individual turbine<br />

locations. A total internal track length of 9.4 km will be required (measured from the site<br />

entrance) to access the turbines, of which approximately 7.5 km will be upgraded FCS tracks<br />

and 1.9 km will be new track construction. The proposed access track configuration is<br />

illustrated on Figure 1.2.<br />

4.5.14 Access tracks will be approximately 5 m wide. The track depth will depend on ground<br />

conditions encountered, however, initial site investigations indicate it is unlikely to be greater<br />

than 0.5 m in most cases. A typical cross section of access track is shown in Figure 4.4.<br />

4.5.15 The access tracks will be used by construction vehicles and will be retained throughout the<br />

lifetime of the proposed wind farm <strong>for</strong> use by maintenance vehicles.<br />

4.5.16 The edges of the access tracks will be reinstated at the end of the construction period and<br />

vegetation growth will be encouraged on verges or retained <strong>for</strong> future use by the landowner<br />

and/or use <strong>for</strong> countryside recreational purposes.<br />

4.5.17 During operation, access tracks will be gated with galvanised farm gates to discourage<br />

unauthorised vehicle access but to allow pedestrian access under the terms of the Scottish<br />

Outdoor Access Code. Any signage will be discrete, fixed to the gate or gateposts and<br />

agreed in advance with Stirling Council. The requirements of the Scottish Outdoor Access<br />

Code will be adhered to throughout the construction and operation of the wind farm, with<br />

pedestrian access to much of the site remaining open and usable.<br />

4.5.18 7 m wide crossing points are provided along the internal access tracks at 250 m intervals to<br />

enable <strong>for</strong>estry operations to continue. 30 m long passing places are also provided at a<br />

distance of 500 m apart.<br />

On Site Borrow Pits<br />

4.5.19 The borrow area assessment has identified three borrow area locations which coincide with<br />

rock exposures in sloping ground or at existing borrow pit locations, referred to as Borrow<br />

Areas A, B and C. These are located at grid reference NS 6905 8580, NS 6931 8562, NS<br />

6905 8580 respectively. The rock in each of the three borrow areas is extrusive basaltic<br />

lavas. The fine grained basic rocks are suitable <strong>for</strong> use as aggregates in construction. Peat<br />

deposits are not anticipated to be present at the proposed borrow pit locations but limited<br />

mineral soil/glacial till is anticipated at Borrow Area B and C.<br />

4.5.20 The rock in Borrow Areas A and B is of a macroporphyritic nature and is there<strong>for</strong>e considered<br />

to be less desirable <strong>for</strong> use in concrete aggregate. The rock in Borrow Area C is<br />

microporphyritic and is there<strong>for</strong>e considered more suitable <strong>for</strong> sourcing concrete aggregate.<br />

4.5.21 Borrow pit dimensions and volumes have been estimated and probable extraction methods<br />

identified. The total volume of materials available from the proposed borrow pits identified is<br />

67,500 m 3 which provides about twice the estimate of aggregate volume required.<br />

4.5.22 Detailed ground investigations including geotechnical testing and slope stability will be<br />

required to in<strong>for</strong>m detailed design of the proposed borrow pits.<br />

Description of the Proposed Development


Carron Valley Wind Farm<br />

4.5.23 Borrow Areas A and B will be reinstated in line with the requirements of FCS. Borrow Area C<br />

will be utilised <strong>for</strong> the storage of some ripped and crushed material which will be recovered as<br />

needed <strong>for</strong> the purposes of track maintenance throughout the lifetime of the wind farm.<br />

Temporary Construction Compound<br />

4.5.24 During the construction period, a temporary hardcore construction compound area will be<br />

required in the location indicated in Figure 1.2. The compound will comprise a hard standing<br />

of approximately 50 m x 50 m to provide space <strong>for</strong>:<br />

• A refuelling area;<br />

• Materials storage;<br />

• Temporary site office cabins and welfare facilities <strong>for</strong> contractors.<br />

4.5.25 The location <strong>for</strong> the temporary construction compound has been selected on the basis of its<br />

practicality, low habitat value and limited visual impact. Once the use of the compound is<br />

complete the area will also be fully restored.<br />

4.5.26 The compound will be constructed using a geogrid base, or similar, to facilitate removal and<br />

reinstatement. Within six months of the proposed wind farm becoming operational, all<br />

temporary cabins, machinery and equipment will be removed and the laydown area fully<br />

restored.<br />

Stone and Concrete Requirements and Sourcing<br />

4.5.27 A concrete batching plant will be located in the construction compound. The plant will<br />

combine sand, site-sourced aggregate, cement, water, and other additives to produce<br />

concrete. The concrete produced in the concrete batching plant will be used <strong>for</strong> the<br />

foundations of the turbines, buildings, paving material <strong>for</strong> roads and parking areas, pipes<br />

surrounds and precast concrete components. Cement and suitably graded sand will be<br />

imported to produce construction concrete. This will reduce the imported material to less<br />

than a third of the required tonnage of concrete.<br />

4.5.28 Settlement lagoons will be provided to prevent cement and concrete washing out into<br />

groundwater or surface water. These measures are described in more detail in Chapter 13:<br />

Hydrology, Hydrogeology and Ground Conditions.<br />

Site Drainage<br />

4.5.29 Drainage trenches will be required adjacent to the proposed access tracks to control the flow<br />

of water around and across them. Drainage pipes flowing perpendicular to the track will be<br />

installed at maximum intervals of 50 m to prevent ponding and ensure the existing site<br />

hydrology is largely maintained. This action will also preserve the structural integrity of the<br />

access road. As far as reasonably practicable, artificial drainage pipes will coincide with<br />

naturally occurring drainage channels or other low-lying areas. Where the track slopes<br />

downhill, cross drains or 'waterbars' will be placed to prevent excessive surface water flow<br />

along the track.<br />

4.5.30 Detailed track drainage proposals will be presented to Stirling Council and key consultees<br />

prior to works commencing <strong>for</strong> each relevant track section.<br />

4.5.31 Drainage is discussed further in Chapter 13: Hydrology, Hydrogeology and Ground<br />

Conditions.<br />

Watercourse Crossings<br />

4.5.32 No new watercourse crossings will be required. It will be necessary to upgrade a total of six<br />

existing watercourse crossings and concept design drawings are shown in Figure TA13.3.1 in<br />

Appendix 13.3.<br />

4.5.33 The crossing locations have been inspected and the crossing structure type chosen taking<br />

into the potential impact on river flows, geomorphology and ecology. Further detail on the<br />

watercourse crossings are included in Appendix 13.3.<br />

4.6 Construction of the Proposed Wind Farm<br />

4.6.1 The proposed wind farm will be constructed in accordance with relevant health and safety<br />

legislation including the Health and Safety at Work Act 1974. All site based activities will be<br />

conducted in accordance with the Construction (Design and Management) Regulations 2007,<br />

which implement parts of the EU Mobile and Temporary Construction Sites Directive.<br />

Principal Site Operations<br />

4.6.2 The principal construction activities will include:<br />

• Clearance of <strong>for</strong>estry and other land <strong>for</strong> wind farm development and associated<br />

infrastructure (approximately 33.52 ha) – it is anticipated that all felling will have taken<br />

place prior to wind farm construction activities with the exception of keyhole felling<br />

which can only take place after the tracks towards the keyholes are in place;<br />

• Construction of temporary construction compound;<br />

• Formation of three borrow areas;<br />

• Upgrading of existing access track and construction of new access tracks and<br />

widening of watercourse crossings;<br />

• Access track passing places and <strong>for</strong>estry crossing points;<br />

• Construction of turbine foundations and associated hard standings;<br />

• Construction of a turbine laydown area;<br />

• Excavation of trenches and laying of overhead electrical cables;<br />

• Construction of a control building and electrical equipment;<br />

• Erection and commissioning of wind turbines;<br />

• Reinstatement of the temporary construction compound.<br />

4.6.3 Work will commence with the clearance of <strong>for</strong>estry and land, construction of the entrance to<br />

the construction compound access road and the <strong>for</strong>mation of the temporary construction<br />

compounds. Construction of the access to the turbine tracks, turbine foundations, associated<br />

infrastructure and subsequent erection of the wind turbines will then be carried out in a<br />

sequential basis, progressing through the site. Table 4.3 shows the typical construction<br />

sequence.<br />

4.6.4 All construction activities will adhere to pollution control measures which will be detailed in a<br />

Health, Safety and Environmental Management System (HSEMS, see Section 4.11 and<br />

Appendix 4.4) drawn up in consultation with Stirling Council and other relevant stakeholders<br />

prior to construction. Adherence to the requirements of the HSEMS will be a contractual<br />

obligation placed upon the contractor.<br />

4.6.5 Enabling works will be required prior to commencement of the main construction works.<br />

These works will be phased in the pre-construction period, and include:<br />

• Detailed site investigation works;<br />

• Surface and groundwater monitoring;<br />

• Consultation with the appropriate authorities regarding turbine deliveries.<br />

4.6.6 The temporary construction compound will be constructed to provide a secure area <strong>for</strong><br />

storage of materials, plant maintenance and refuelling, concrete batching, welfare facilities<br />

and vehicle parking. Temporary utilities connections, in the <strong>for</strong>m of electrical supply and<br />

potable water supply, will be established. The compound will be <strong>for</strong>med from compacted<br />

hardcore laid over a geo-membrane, and will be enclosed by post and chain-link fencing.<br />

4.6.7 Three borrow areas will be <strong>for</strong>med to provide aggregate <strong>for</strong> access track construction and <strong>for</strong><br />

concrete aggregate. The quality of the basalt rock varies between the borrow area locations.<br />

Details of the borrow area development, quantities and quality is provided in Appendix 13.1.<br />

4.6.8 The existing <strong>for</strong>est access tracks will be upgraded to provide access <strong>for</strong> the wind farm<br />

construction by widening to minimum of 5 m. New tracks also 5 m wide will lead off the main<br />

access track to each turbine location.<br />

4.6.9 Passing places will be provided to facilitate the safe movement of traffic. The passing places<br />

are designed to be suitable <strong>for</strong> the anticipated large turbine delivery vehicles and lifting<br />

cranes as well as the <strong>for</strong>estry maintenance vehicles.<br />

4.6.10 Construction of turbine foundations will be <strong>for</strong>med by excavation into the mineral sub-soil and<br />

establishment of a suitable <strong>for</strong>mation. The base will be blinded suitable <strong>for</strong> the installation of<br />

a rein<strong>for</strong>cing cage prior to placing the concrete to <strong>for</strong>m the support foundation <strong>for</strong> installation<br />

of the turbine mast. Hard standings will be <strong>for</strong>med adjacent to each turbine along with<br />

turbine laydown area to facilitate the erection of the turbine mast, nacelle and blades using<br />

high lift cranes.<br />

4.6.11 It is anticipated that peat will only be excavated at Turbine 2 and the associated access track.<br />

This turbine foundation will be excavated through the peat until a suitable <strong>for</strong>mation is<br />

exposed. This will either be natural compact mineral soil or weathered rockhead. From the<br />

peat probing survey (see Appendix 13.2) it is anticipated that the excavation will be no<br />

greater than 3 m. The concrete foundation will be <strong>for</strong>med and backfilled with excavated soil<br />

and/or suitably sized rock aggregate. The excavated peat will be used to reinstate the<br />

disturbed area around this turbine.<br />

4.6.12 Trenches will be excavated parallel and adjacent to the access track <strong>for</strong> turbine power,<br />

control and monitoring cables. All electrical trans<strong>for</strong>mers (except the turbine trans<strong>for</strong>mers<br />

which are located outside the turbine bases) and control equipment will be installed in the<br />

control building.<br />

Indicative Construction Programme<br />

4.6.13 Construction of the proposed wind farm is estimated to take approximately 20 months,<br />

including commissioning and site reinstatement. Table 4.3 below provides an indicative<br />

schedule of construction activities. This programme is indicative only and could vary<br />

Construction Working Hours<br />

4.6.15 Construction activities will be carried out between the hours of 08:00 to 18:00 during the<br />

week days and 08:00 to 13:00 on Saturdays considering non-peak hour traffic. In the event<br />

that construction will be required outwith these hours, e.g. <strong>for</strong> delivery of abnormal loads,<br />

consent will be agreed in advance with Stirling Council.<br />

Materials and Waste Management<br />

4.6.16 Construction practices will be implemented to minimise the use of raw materials and<br />

maximise the use of secondary aggregates and recycled or renewable materials. In addition,<br />

waste material generated by the proposed development will be reduced and re-used or<br />

recycled on site as appropriate. Methods to incorporate best practice waste management<br />

techniques and consideration of the waste hierarchy into all aspects of the site management<br />

are identified in the following section and will be incorporated into the Health, Safety and<br />

Environmental Management Plan (HSEMS, see Section 4.11 and Appendix 4.4).<br />

4.6.17 A Site Waste Management Plan (SWMP) will be required as part of the HSEMS to ensure<br />

building materials and any waste material is managed in accordance with best practice<br />

through recycling, reuse and recovery where appropriate. By implementing a SWMP the site<br />

is expected to reduce waste arisings and associated costs.<br />

Waste Streams<br />

Construction<br />

4.6.18 A number of potential waste streams have been identified in the construction phase. Wastes<br />

likely to arise during the construction phase of the wind farm development include the<br />

following:<br />

• Wastes from excavation, gravel, tailings and crushed rocks;<br />

• Oil wastes including hydraulic oils, engine gear and lubricating oils;<br />

• Wastes from metal degreasing and machinery maintenance, including solvents;<br />

• Packaging, including absorbents, wiping cloths, filter materials and protective clothing;<br />

• Miscellaneous waste including batteries and accumulators, welfare facility waste;<br />

• Mixed construction waste including concrete waste.<br />

4.6.19 Management of wastes during will include the following:<br />

• Waste Resulting From Excavations - Likely to comprise excavated stone, rock and<br />

gravel. It is proposed to recycle this as aggregate in roads or fill where suitable.<br />

Smaller size class of aggregate can be crushed, screened and then used as backfill <strong>for</strong><br />

cable trenches, if required, to minimise sand requirements. Generally, materials<br />

generated from these activities will be re-used or recycled where appropriate on-site.<br />

All topsoil and subsoil (where present and requiring removal) will be reused where<br />

possible.<br />

• Oil Wastes - Disposal of oil and any accumulation of fuel residues in the bunded<br />

refuelling area will be disposed of in accordance with Duty of Care requirements by a<br />

suitably licensed or permitted facility.<br />

• Packaging - Most packaging materials will be returned to manufacturers, including<br />

cable drums and pallets.<br />

Description of the Proposed Development


Carron Valley Wind Farm<br />

• Wastes Not Otherwise Specified - Any septic tank systems will be emptied by licensed<br />

carriers in line with Duty of Care requirements.<br />

4.6.20 In addition, the contractor will be obliged to comply with a number of guiding principles in<br />

relation to the effective management of wastes:<br />

• Storage and handling of waste site - Operatives will segregate different waste types to<br />

maximise potential <strong>for</strong> re-use. Waste containers will be clearly marked with intended<br />

content. Only containers suitable <strong>for</strong> contents will be used to minimise risk of<br />

accidental spillages and leaks. Covers and bunds will be provided to prevent<br />

evaporation and spillage of wastes, and to ensure that wastes cannot be blown away.<br />

• Care will be taken to dispose of waste arising in accordance with the Environmental<br />

Protection Act 1990 (as amended) and the Environmental Protection (Duty of Care)<br />

Regulations 1991 (as amended). Waste leaving the site will be accompanied by a<br />

waste transfer note or special waste consignment note that records the description of<br />

the waste, its current holder, the person collecting it and its destination.<br />

• Reducing, reusing and recycling - Operative will reuse and recycle wastes generated<br />

on-site whenever possible.<br />

Operation<br />

4.6.21 Wind turbines produce very limited pollutants or waste emissions. However, there will be a<br />

small amount of waste associated with the operation of the proposed wind farm. This is likely<br />

to be restricted to waste associated with the substation compound from employees and<br />

visiting contractors, storage of chemicals/ fuel, septic tank sludge and waste oils from, <strong>for</strong><br />

example, gearbox maintenance.<br />

4.6.22 Sludge from one closed on-site septic tank will be collected by an authorised carrier and<br />

disposed of at a consented wastewater treatment works.<br />

Decommissioning<br />

4.6.23 It is anticipated that waste generated during decommissioning will be similar to that<br />

generated during construction. However, the decommissioning and disposal of end-of-life<br />

turbines will generate a greater amount of waste. Many of the components of end-of-life<br />

turbines are likely to be recyclable.<br />

4.6.24 The-end-of-life scenario <strong>for</strong> turbine disposal cannot be accurately predicted. However,<br />

turbines will be disposed of in accordance with industry best practice at the time. If there is<br />

potential <strong>for</strong> recycling components, these will be clearly identified in the decommissioning<br />

plan.<br />

Soils<br />

4.6.25 Some soils will be extracted from the access route track (modifications to the existing access<br />

track to the proposed wind farm site and creation of internal tracks within the site),<br />

hardstanding areas, cable trenches and turbine bases. In addition there will be a temporary<br />

construction compound and a wind farm substation building that will require soil stripping. A<br />

full soils survey and soils balance assessment will be carried out prior to development.<br />

4.6.26 All necessary waste transfer licences will be acquired <strong>for</strong> any soil movement. Where<br />

possible, recycled or reprocessed waste soils will be used. At all stages, development will<br />

4.7.1 The location <strong>for</strong> the temporary construction compound has been selected on the basis of its<br />

practicality, low habitat value and limited visual impact. Once the use of the compound is<br />

complete the area will be restored.<br />

4.7.2 The temporary construction compound will be reinstated once all construction activity is<br />

complete. The compound will be constructed using a geogrid base, or similar, to facilitate<br />

removal and reinstatement. Within six months of the proposed wind farm becoming<br />

operational, all temporary cabins, machinery and equipment will be removed and the laydown<br />

area fully restored. The reinstatement will be carried out by removal of all plant and<br />

accommodation, and then the removal of the compacted hard surface be<strong>for</strong>e replacing<br />

topsoil and then seeding as appropriate to facilitate the re-establishment of natural<br />

vegetation.<br />

4.7.3 Following completion of the wind farm construction and commissioning of the turbines, all<br />

internal access tracks will be reinstated.<br />

4.8 Operation of the Proposed Wind Farm<br />

4.8.1 Wind turbines are extremely reliable, requiring minimal intervention and maintenance during<br />

operation. They are designed and constructed to withstand extreme wind and weather<br />

conditions. The turbines selected <strong>for</strong> this site will have a proven record in terms of safety and<br />

reliability. In addition, all power transmission at the proposed wind farm will be in compliance<br />

with UK guidelines and legal requirements.<br />

4.8.2 Employees from the turbine manufacturer and/or suitably qualified contractors employed<br />

locally will carry out maintenance at regular intervals across the 25 year operational life of the<br />

proposed wind farm. Routine maintenance and servicing is carried out twice per year. In<br />

addition, there is an initial service three months after commissioning.<br />

4.8.3 The following turbine maintenance will be carried out, along with any other maintenance<br />

required by manufacturers’ specifications:<br />

• Initial service;<br />

• Routine maintenance and servicing;<br />

• Blade inspection.<br />

4.8.4 Servicing will include tasks such as maintaining bolts to the required torque, adjusting blades,<br />

inspecting blade tip brakes, inspecting welds in the tower and re-lubricating moving<br />

components. Blade inspections are carried out as required (normally somewhere between<br />

every two and five years).<br />

4.8.5 The likelihood of major operational failures such as fire, collapse or blade throw is extremely<br />

low. The Supervisory Control and Data Acquisition (SCADA) system provides monitoring<br />

in<strong>for</strong>mation, which can detect and provide warning of abnormal operating conditions to allow<br />

automatic shut down and intervention be<strong>for</strong>e emergency situations occur.<br />

Carron Valley Wind Farm<br />

4.8.6 Should unexpected events occur, on-site appropriate maintenance works will be carried out.<br />

In some situations cranes may need to be deployed which will constitute an abnormal load<br />

and will be subject to the consent of the relevant roads authority in respect of delivery.<br />

There<strong>for</strong>e, the crane pads adjacent to turbines will be retained <strong>for</strong> this purpose.<br />

4.8.7 Ongoing track maintenance will generally be undertaken in the summer months when tracks<br />

are likely to be drier. Safe access will be maintained all year round.<br />

4.8.8 Sensor activated external lighting will be located at the substation building to ensure the<br />

safety of operators accessing these buildings.<br />

4.8.9 A number of in<strong>for</strong>mation signs will be required at the site during construction and operation of<br />

the proposed wind farm. Signage will include:<br />

• Panel signs indicating the presence of the site entrance;<br />

• Signage on each turbine, indicating the turbine number, potential hazards and an<br />

emergency contact telephone number;<br />

• Substation building signage with health and safety in<strong>for</strong>mation and an emergency<br />

contact telephone number; and<br />

• Other operational signage as required (e.g. Buried High <strong>Vol</strong>tage (HV) Cable Route,<br />

Turbine Locations, etc).<br />

4.8.10 Fencing will be erected around the substation building. It is anticipated that this will be<br />

permanent 2.4 m high palisade fencing.<br />

4.9 Decommissioning of the Proposed Wind Farm<br />

4.9.1 At the end of the 25 year operational life of the proposed wind farm, if the operational period<br />

is not extended the proposed wind farm will be decommissioned and the site reinstated as<br />

approved by the appropriate authority and relevant statutory consultees at that time, and in<br />

agreement with FCS.<br />

4.9.2 Decommissioning will involve:<br />

• Dismantling and removal of the wind turbines and underground electrical equipment;<br />

• Removal of turbine foundations to 1 m below ground level;<br />

• Demolition and removal of the substation building and compound;<br />

• Reinstatement of land affected in accordance with best practice at the time;<br />

• Electrical cables will be cut off below ground level, de-energised and left in the ground.<br />

4.9.3 The turbines will be dismantled and removed from the site in a manner similar to that of their<br />

erection. Where possible turbine components will be recycled. Turbine foundations will be<br />

broken out to below ground level. Typically this will involve the removal of the upstand plinth<br />

to the top surface of the main foundation base. The removal of the turbine components will<br />

not result in abnormal loads such as those required <strong>for</strong> construction. Wherever possible, the<br />

components will be reduced to a size that will be manageable on standard HGVs.<br />

4.9.4 Demolition of the substation building will involve removal of the internal equipment, followed<br />

by demolition and removal of the building. Access tracks will be reinstated in accordance<br />

with best practice at the time of decommissioning and in line with the requirements of FCS.<br />

4.9.5 In<strong>for</strong>mation relating to decommissioning will be outlined within the Decommissioning Plan,<br />

which will be submitted <strong>for</strong> approval to the appropriate authorities prior to cessation of<br />

operations and decommissioning. This will set out how the turbines and other infrastructure<br />

will be removed and the site restored. Alternatively, an application may be made <strong>for</strong><br />

permission to extend the duration of the proposed wind farm or to replace the turbines with a<br />

new turbine model to take advantage of changes in technology. Any new application would<br />

be subject to the requisite further environmental appraisal at the appropriate time.<br />

4.9.6 Decommissioning activities will be carried out in accordance with relevant Health and Safety<br />

Regulations and Construction Regulations at the time of decommissioning.<br />

4.10 Impact of Wind Farm on Forestry Operations<br />

Overview of Forestry Issues and Wind Farm Development<br />

4.10.1 The development of a wind farm within the <strong>for</strong>est will be carefully managed to minimise the<br />

impact on <strong>for</strong>estry operations. In the case of Cairnoch Hill the positioning of the turbines has<br />

been considered to allow <strong>for</strong> this impact to be in most cases be of little significance.<br />

4.10.2 Some area will be lost to <strong>for</strong>estry completely (turbine bases, roads, crane pads, etc) whilst<br />

other areas will be managed in a way to reduce its availability <strong>for</strong> use <strong>for</strong> wood production<br />

during the life of the wind farm.<br />

4.10.3 An assessment of the current compartments adjacent to the keyholes, timescale <strong>for</strong> felling<br />

within the current FDP and potential growth rates based on Yield Class 12, Sitka Spruce<br />

obtained from the Forestry Commission Booklet 34, Forest Management Tables (Forestry<br />

Commission, 1971) has been carried out and is presented in Appendix 4.3.<br />

4.10.4 The areas most affected are the turbine keyholes that are likely to be maintained as relatively<br />

open areas <strong>for</strong> their radius (77.5 metres). However, if the proposed wind farm receives<br />

planning permission PfR is keen to explore with SNH and Stirling Council potential<br />

opportunities to research different keyhole management techniques and their effects on<br />

habitats and species through varying and monitoring keyhole management practices <strong>for</strong> a<br />

defined period of operation of the wind farm. This would be discussed in more detail and<br />

agreed with SNH and other interested parties post-consent.<br />

4.10.5 Road access to the turbine positions will need to be created where required. Within the <strong>for</strong>est<br />

sections of road are to be constructed to access parts not currently served by existing roads,<br />

this applies to only a couple of minor sections of road beyond that already identified in the<br />

FDP as being required to resource the plan.<br />

4.10.6 Three borrow pits to provide the stone required <strong>for</strong> roads and crane base construction are<br />

needed. These are identified within the current amendment to the FDP and would partly been<br />

required <strong>for</strong> the roads identified on the plan.<br />

4.10.7 Internal track widening and upgrading of stream or burn crossings are necessary to take the<br />

increased vehicle weight needed and are considered to be an improvement to the internal<br />

<strong>for</strong>est roads.<br />

4.10.8 Infrastructure including the anemometry mast, construction compound and passing places<br />

will have an impact on the available <strong>for</strong>est area.<br />

4.10.9 These impacts are considered below and broken down into various degrees, either temporary<br />

or permanent, in Appendix 4.3.<br />

Proposed Wind Farm and Forest Impacts Analysis<br />

4.10.10 The current total productive <strong>for</strong>est found at Cairnoch Hill is 505 hectares. The amended FDP<br />

proposes to restructure the <strong>for</strong>est to reduce the impacts of felling as a result of the plantations<br />

being planted within a short time frame. The current amendment to the FDP includes the<br />

recent clear felling and windblow.<br />

4.10.11 Recent wind damage in January 2012 has increased the wind blow affected area from 71 ha<br />

to 110 ha. If this is combined with the area currently in the restocking phase (100 ha planted<br />

in the last 10 years) it is a considerable percentage of the <strong>for</strong>est. The majority of the<br />

remaining <strong>for</strong>est will be felled within the next 20 years.<br />

4.10.12 Baseline impacts from the development of the wind farm relate predominantly to the removal<br />

of certain areas of land from productive <strong>for</strong>estry to facilitate wind farm infrastructure. Loss of<br />

<strong>for</strong>estry as a direct result of the wind farm equates to 33.52 ha, of which 2.4 ha will be lost<br />

due to the creation of hard surfaces and solid bases within the <strong>for</strong>est. 28.5 ha will be taken<br />

out of production to accommodate the keyhole area and will be maintained as mostly clear<br />

open spaces within the <strong>for</strong>est or using alternative management techniques <strong>for</strong> research<br />

purposes. This land can revert back to <strong>for</strong>est once the turbines are removed.<br />

4.10.13 The majority of proposed turbine locations are within areas of restocking or current<br />

windblown areas (ten of the fifteen turbines are located in either areas needing to be cleared<br />

in the next two years or in restocking areas). This has been a very deliberate exercise<br />

through the design evolution process in order to minimise any unnecessary removal of nonmature<br />

<strong>for</strong>estry to facilitate wind farm infrastructure.<br />

4.10.14 Roads will need to be widened and additional passing places constructed and this will result<br />

in improved access <strong>for</strong> future <strong>for</strong>estry operations.<br />

4.10.15 In line with the Scottish Government’s Policy on Control of Woodland Removal (Forestry<br />

Commission Scotland, 2009), the net loss of <strong>for</strong>est cover (33.52 ha) will be compensated <strong>for</strong><br />

by restocking either within Cairnoch Hill or within the Carron Valley <strong>for</strong>est block to the south<br />

of the reservoir. The temporary loss of <strong>for</strong>est production in addition can be mitigated <strong>for</strong> by<br />

additional restocking or as an acceptable increase in open space within Cairnoch Hill and the<br />

habitat diversity these would result in.<br />

4.10.16 An assessment of impacts in relation to <strong>for</strong>estry land use is included within Chapter 15:<br />

Socioeconomics, Tourism, Recreation and Land Use.<br />

4.11 Securing Environmental Management – the Health, Safety and<br />

Environmental Management System<br />

4.11.1 The appointed contractor will have overall responsibility <strong>for</strong> environmental management on<br />

the site. The services of specialist advisors will be retained as required and may include, <strong>for</strong><br />

example, an archaeologist and/or ecologist to advise on specific issues. The Project<br />

Manager will ensure construction and decommissioning activities are carried out in<br />

accordance with the mitigation measures outlined in this document.<br />

4.11.2 To ensure all mitigation measures outlined within this Environmental <strong>Statement</strong> (<strong>ES</strong>) are<br />

carried out, contractors will be required to develop and adhere to a Health, Safety and<br />

Environmental Management System (HSEMS) throughout the construction process. An<br />

indicative outline structure of the HSEMS is included in Appendix 4.4, and the contractor will<br />

be required to develop this to include site specific details in the <strong>for</strong>m of a Pollution Prevention<br />

and Emergency Response Plan, Traffic Management Plan, Noise Management Plan. The<br />

HSEMS will be agreed with Stirling Council and all relevant statutory bodies prior to<br />

commencement, and will be monitored by the Construction Project Manager and the<br />

Ecological Clerk of Works (ECoW). The HSEMS will be drafted to comply with SEPA’s<br />

Pollution Prevention Guidelines (PPG) and best practice as advocated by the Construction<br />

Industry Research and In<strong>for</strong>mation Association (CIRIA).<br />

4.11.3 In line with the Pollution Prevention and Emergency Response Plan, contractors will be<br />

required to adhere to the following in order to reduce or mitigate the environmental effect of<br />

the construction process:<br />

• Conditions to be adhered to under the planning permission;<br />

• Requirements of SEPA;<br />

• Any other relevant mitigation measures identified in this <strong>ES</strong>.<br />

4.11.4 A copy of any conditions associated with the planning permission will be incorporated into<br />

tender documents and contracts. The selection criteria <strong>for</strong> the construction contractor will<br />

include their record in dealing with environmental issues and provision of evidence that they<br />

have incorporated all environmental requirements into their method statements.<br />

4.11.5 A range of general best practice measures will be incorporated into the HSEMS and<br />

employed on site to minimise any potential effects.<br />

4.11.6 Where specific measures are proposed in response to a potential impact identified this is<br />

included in the appropriate section of this <strong>ES</strong> and a summary of all proposed mitigation<br />

measures is presented in Chapter 16: Summary of Effects and Mitigation.<br />

5 Planning Policy Overview<br />

5.1 Introduction to Planning Guidance and Context<br />

5.1.1 This chapter identifies the European Union, United Kingdom and Scottish Government’s<br />

climate change and renewable energy targets. The main driver <strong>for</strong> these targets has been<br />

the need to reduce greenhouse gases in order to combat climate change, and the<br />

requirement to fill the resulting energy gap with renewable energy alternatives, including wind<br />

energy.<br />

5.1.2 The chapter also identifies the Development Plan policies and material considerations<br />

relevant to the determination of the planning application <strong>for</strong> the proposed Carron Valley Wind<br />

Farm. These policies and material considerations provide the context <strong>for</strong> the more detailed<br />

topic analysis as set out in Chapters 7 to 15 of this Environmental <strong>Statement</strong> (<strong>ES</strong>).<br />

5.1.3 It is not the purpose of this chapter to provide an assessment of the proposed wind farm<br />

against planning policy. It sets out the context in which development proposals will be<br />

considered. The detailed assessment of the proposed wind farm against the development<br />

plan and material considerations is contained within a separate supporting Planning<br />

<strong>Statement</strong> (PS) which accompanies the planning application<br />

5.2 International and National Context<br />

Climate Change and Renewable Energy Targets<br />

European Union Context<br />

5.2.1 Based upon the Intergovernmental Panel on Climate Change (IPCC) findings, the European<br />

Commission’s analysis shows that global emissions will have to be stabilised by around<br />

2020, then reduced by at least 50 % of 1990 levels by 2050, with developed countries<br />

collectively cutting their emissions to 30 % below 1990 levels by 2020 and 60-80 % by 2050.<br />

5.2.2 In 2008, in order to address the Intergovernmental Panel on Climate Control (IPCC) findings,<br />

the European Union (EU) unilaterally agreed a Climate and Energy Package which aims to<br />

deliver cuts in emissions of 20 % by 2020. The EU has committed to strengthening this<br />

target to 30 % provided other industrialised countries commit to a comparable ef<strong>for</strong>t and<br />

developing countries contribute adequately to global action.<br />

5.2.3 In April 2009 the European Commission adopted a new European <strong>Renewables</strong> Directive<br />

(RD) which sets the ambitious target of obtaining 20 % of all the EU’s energy (not just<br />

electricity) to come from renewables sources by 2020. The RD was negotiated based on this<br />

20 % target and resulted in country “shares” of this target. For the UK, the share is that 15 %<br />

of all final energy consumption, should be accounted <strong>for</strong> by energy from renewable sources.<br />

This 15 % target equates to approximately 230 gigawats (GW) of installed capacity.<br />

United Kingdom Context<br />

5.2.4 The UK’s Energy White Paper 2007 states that “we are determined to become a low carbon<br />

economy” (DTI, 2007) and reaffirms the UK Government’s four energy priorities as reducing<br />

CO 2 emissions, maintaining energy security, promoting sustainable growth and tackling fuel<br />

poverty. Regarding the first of these objectives, the UK Government has set a goal of<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

reducing CO 2 emissions to 20 % below 1990 levels by 2010 and in 2006 launched the UK<br />

Climate Change Programme.<br />

5.2.5 The Climate Change Act 2008 established a system of 5-year carbon budgets to manage the<br />

trajectory of UK emissions to a target of 80 % cuts by 2050. It also allowed <strong>for</strong> the<br />

establishment of the Committee on Climate Change to provide advice to the UK Government<br />

and devolved administrations on the setting of carbon budgets and other climate change<br />

issues.<br />

5.2.6 In December 2008, the Committee on Climate Change (CCC) proposed a set of ‘interim’<br />

carbon budgets covering the five-year periods 2008-12, 2013-17, and 2018-22. These<br />

budgets would see the UK’s greenhouse gas emissions in 2020 fall to at least 34 % below<br />

their 1990 level. The Committee also proposed stretching ‘intended’ budgets which would<br />

see emissions reduce by 42 % by 2020. In April 2009 the UK Government announced that it<br />

would set its carbon budgets based on the Committee’s interim budgets.<br />

5.2.7 The UK Renewable Energy Roadmap was published by the Department of Energy and<br />

Climate Change (DECC) in July 2011 and sets out a comprehensive action plan of how the<br />

UK Government plans to accelerate the UK’s deployment and use of renewable energy in<br />

order to meet the EU’s legally binding target that 15 % of all energy is to come from<br />

renewable sources by 2020. The Roadmap focuses on the eight key renewable energy<br />

technologies (including onshore wind) which are particularly significant to meeting the 15 %<br />

target due to their cost effectiveness, potential level of deployment, and importance to the<br />

UK’s 2050 energy mix. The Roadmap identifies that these eight key renewable energy<br />

technologies can deliver approximately 90 % of the generation necessary to meet the 15 %<br />

target, with onshore wind identified as having the potential to generate approximately 13 GW<br />

by 2020 (compared to around 4 GW today). Achieving this 9 GW increase would require an<br />

annual growth rate in the UK of onshore wind of 13 % over the next decade.<br />

5.2.8 The <strong>Renewables</strong> Obligation (RO) was introduced into the UK in April 2002 and is the<br />

principal mechanism by which the UK aims to reach its targets <strong>for</strong> renewable energy. The<br />

RO requires licensed electricity suppliers to source a specific and annually increasing<br />

percentage of the electricity they supply from renewable sources. The percentage target<br />

began at 3 % in 2003 and is set to rise progressively to 15.4 % by 2015. Under the scheme,<br />

one <strong>Renewables</strong> Obligation Certificate (ROC) is issued <strong>for</strong> each megawatt hour (MWh) of<br />

eligible renewable output generated. The ROCs can be used by suppliers to demonstrate<br />

compliance with the RO and can also be sold (traded) to suppliers so that they may fulfil their<br />

obligation. In 2011, power generation from renewable sources eligible under the <strong>Renewables</strong><br />

Obligation), indicated that further significant development in renewable energy sources is<br />

needed to meet this target.<br />

Scottish Context<br />

The Climate Change (Scotland) Act 2009<br />

5.2.9 The Climate Change (Scotland) Act requires Scotland’s greenhouse gas emissions to be at<br />

least 80 % lower in 2050 compared with 1990 levels (known as the “2050 target”). An interim<br />

target also requires emissions to be at least 42 % lower by 2020 compared with 1990 levels.<br />

The Act also requires the Scottish Government to act:<br />

• To reduce greenhouse gas emissions year on year, every year from 2011 to 2050;<br />

• To increase the rate of reduction from 2020 onwards to at least 3 % per year; and<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

• To specify more detailed annual targets in 2010, <strong>for</strong> each year to 2022.<br />

5.2.10 The Scottish Government recognises that the displacement of fossil fuel heat and power<br />

generation is important to reducing emissions.<br />

The Climate Change Delivery Plan (2009)<br />

5.2.11 The Scottish Government issued the Climate Change Delivery Plan, entitled ‘Meeting<br />

Scotland’s Statutory Climate Change Targets’ in June 2009. The Plan sets out the high level<br />

measures required in each sector to meet Scotland’s statutory climate change targets to<br />

2020 as set in the Climate Change (Scotland) Act 2009; and the work to be done over the<br />

next decade to prepare <strong>for</strong> the more radical changes needed by 2030 if the 80 % emission<br />

reduction target is to be achieved.<br />

5.2.12 For the electricity sector, targets have been set <strong>for</strong> the percentage of electricity demand,<br />

which requires to be obtained from renewable energy sources by 2020. The current target,<br />

which was set by the Scottish Government in May 2011, is <strong>for</strong> 100 % of Scotland’s gross<br />

annual electricity consumption to be generated from renewable sources by 2020. This 100 %<br />

renewables target roughly equates to approximately 16 GW of installed capacity (compared<br />

to around 2.4 GW today) and is the most ambitious target in Europe.<br />

5.2.13 Paragraph 3.20 of the Plan notes that the requirement on the UK to meet EU renewable<br />

targets by 2020, equating to 15 % of all energy use from renewable sources, will lead to<br />

strong demand from elsewhere in the UK <strong>for</strong> Scottish renewable electricity.<br />

The Scottish <strong>Renewables</strong> Action Plan (2009)<br />

5.2.14 The Scottish Government issued the <strong>Renewables</strong> Action Plan (RAP) in June 2009. The RAP<br />

identifies what needs to happen in the renewables sector and by when in order to meet the<br />

Scottish Government’s renewable energy targets, with a particular focus on actions needed<br />

over the immediate 24-month period.<br />

5.2.15 The RAP identifies collective actions by government, its agencies and partners, to ensure<br />

that 20 % (this has now been increased to 30 %) of Scotland’s energy use comes from<br />

renewable sources by 2020. Key renewables objectives as set out in the RAP include those:<br />

• To maximise the economic, social and environmental potential of Scotland’s renewable<br />

resource, across different technologies;<br />

• To establish Scotland as a UK and EU leader in the field;<br />

• To ensure maximum returns <strong>for</strong> the Scottish domestic economy; and<br />

• To meet targets <strong>for</strong> energy from renewables, and <strong>for</strong> emissions reductions, to 2020<br />

and beyond.<br />

5.2.16 The RAP refers to Scottish and UK structures and makes it clear that the Scottish<br />

Government is continuing to engage very closely with the UK Government on the shape and<br />

scope of renewable energy legislation and the financial incentives that they create. There is<br />

reference to the <strong>Renewables</strong> Obligation (RO) mechanisms and the RAP states that Scottish<br />

Government is working with “UK colleagues on the further changes to the RO required to<br />

align it with the demands of the EU 20 % target.”<br />

5.2.17 Section 4 of the RAP highlights that each of the technology sectors will have its own part to<br />

play in helping Scotland to meet its energy targets “and ministers are committed to a diverse<br />

renewables mix to maximise the scope to match supply with demand and to enhance security<br />

of supply.”<br />

5.2.18 Although seeking to use a range of renewable technologies, the RAP recognises that given<br />

the proven status of the technology, onshore wind is expected to provide the majority of<br />

capacity in the timeframe <strong>for</strong> the Scottish Government’s interim and 2020 renewable<br />

electricity targets.<br />

2020 Routemap <strong>for</strong> Renewable Energy in Scotland (2011)<br />

5.2.19 The 2020 Routemap <strong>for</strong> Renewable Energy in Scotland was published in July 2011 and<br />

updates and extends the RAP to reflect the challenge of the Scottish Government’s new<br />

targets <strong>for</strong> renewable energy.<br />

5.2.20 The Routemap identifies that the Scottish Government has committed to meeting the EU’s<br />

2020 renewable energy target of 20 % by setting a new target to source 30 % of energy<br />

demand from renewables by 2020. This is further broken down into 100 % electricity; 11 %<br />

heat; and 10 % transport fuels. This 20 % target goes beyond the legally binding 15 % target<br />

that the EU has set <strong>for</strong> the UK and reflects the higher level of potential and the Scottish<br />

Government’s greater ambition <strong>for</strong> renewables in Scotland.<br />

5.2.21 The Routemap identifies that in order to meet the Scottish Government’s renewable energy<br />

targets <strong>for</strong> 2020, a further increase in consenting and deployment rates will be required.<br />

5.2.22 Sectoral routemaps are provided <strong>for</strong> each of the key renewables technologies that are<br />

anticipated will contribute towards achieving the 2020 targets. With regard to onshore wind,<br />

the ambition is “that by 2020, onshore wind developments ranging from small and<br />

community-scale to large power utility scale maximise engagement with communities;<br />

contribute electricity to renewables targets; and through displacement of fossil fuel<br />

generation, help to reduce fossil fuel consumption.”<br />

5.2.23 It continues that “onshore wind is a mature and relatively low cost renewable technology with<br />

a large supply chain already established. It is capable of being deployed at a high rate.<br />

Onshore wind turbines can make a very large contribution to the progress to Scotland’s<br />

renewable electricity target, and help establish Scotland’s reputation as rapidly becoming the<br />

green powerhouse of Europe.”<br />

5.2.24 Table 5.1 and 5.2 below provide a summary of EU, UK and Scottish targets <strong>for</strong> the use of<br />

energy from renewables and <strong>for</strong> the reduction of greenhouse gas emissions respectively.<br />

5.3 Development Plan<br />

5.3.1 Section 25(1) of the Town and Country Planning (Scotland) Act 1997 states that “where, in<br />

making any determination under the Planning Acts, regard is to be had to the development<br />

plan, the determination is, unless materials indicate otherwise, to be made in accordance with<br />

that plan…”. Section 37(2) states that “in dealing with the application made to a planning<br />

authority <strong>for</strong> planning permission, the authority shall have regard to the provisions of the<br />

development plan, so far as material to the application, and to any other material<br />

considerations.”<br />

5.3.2 The Development Plan in this instance comprises:<br />

• The Clackmannanshire and Stirling Structure Plan (approved 2002) (hereafter referred<br />

to as the CSSP);<br />

• The Clackmannanshire and Stirling Structure Plan Alteration (2004) (hereafter referred<br />

to as the CSSPA);<br />

• The Stirling Council Local Plan (adopted December 1999) (hereafter referred to as the<br />

SCLP); and<br />

• The Stirlingshire Council Local Plan First Alteration (2007) (hereafter referred to as the<br />

SCLPA).<br />

5.3.3 The Development Plan policies of relevance to the proposed Carron Valley Wind Farm are<br />

set out in Table 5.3 below. These are summarised in the following paragraphs, focusing<br />

firstly on those policies specific to wind farm developments and latterly on generic policies<br />

that apply to all development proposals. All policies are covered on a policy subject basis.<br />

Development Strategy<br />

Sustainability<br />

5.3.4 The CSSP recognises that the Council can make a large contribution to Sustainable<br />

Development by providing clear and effective guidance to protect and enhance the<br />

environment. It also assists and supports strategies aimed at creating a better quality of life.<br />

5.3.5 Policy SD1 represents an all-embracing approach to proposed development setting out key<br />

principles. It states:<br />

“In identifying sites <strong>for</strong> development in Local Plans and in the assessment of other<br />

development proposals, the Councils will consider the contribution of the development<br />

to the Plan's strategy of "Working Towards Sustainable Development".<br />

5.3.6 The principles relevant to Carron Valley in this policy require that full account is taken of the<br />

impact on the environment. The precautionary principle will be applied when impacts are<br />

unclear or inconclusive and where there is potential <strong>for</strong> irreversible damage. The CSSP<br />

looks <strong>for</strong> all development to contribute to the enhancement of the quality and distinctiveness<br />

of the environment as well as enhancing employment opportunities, social inclusion,<br />

community safety, urban and rural regeneration. It refers to the need to address the<br />

promotion of efficient use and re-use resources including energy, material, land, buildings<br />

and infrastructure. If adverse impacts are identified mitigation and compensatory measures<br />

will be required; and new developments must be accompanied by the appropriate<br />

infrastructure and other facilities.<br />

5.3.7 The principles of a locational strategy seeks to guide development to sustainable locations<br />

where overall it:<br />

• Reduces the need to travel;<br />

• Minimises adverse impacts;<br />

• Reuses previously developed land;<br />

• Is easily accessible by everyone;<br />

• Promotes urban regeneration and appropriate rural development;<br />

• Is close to strategic public transport corridors; and<br />

• Af<strong>for</strong>ds enhancement opportunities.<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

5.3.8 The CSSP administrative area is divided up into three distinct zones. The Carron Valley<br />

Wind Farm site is located in the Uplands Area in which pressures are different, tending to<br />

focus on the need to support and manage rural economic activities. There is also a need to<br />

promote appropriate rural development.<br />

5.3.9 The SCLPA, Policy LD1 makes clear linkages between the Structure and Local Plan in the<br />

context of “Working Towards Sustainable Development” and seeks to encompass the key<br />

issues which new development should address. This updates policy and acts as guide to the<br />

type of in<strong>for</strong>mation required in all planning applications applying the following sustainable<br />

development principles:<br />

• Conserve and enhance the quality of the built and natural environment.<br />

• Promoting social inclusion, regeneration and safety.<br />

• Achieving integrated transport, improving accessibility, and reducing the need to travel.<br />

• Efficient use and recycling of resources.<br />

• Addressing the impacts of new development.<br />

• Delivering the infrastructure to serve new development.<br />

5.3.10 The Council recognises that not all developments will be able to meet the above criteria.<br />

Renewable Energy<br />

5.3.11 The CSSP recognises the significant role which renewable energy has to play in supporting<br />

the Scottish climate change programme and the UK Government’s policy <strong>for</strong> the development<br />

of renewable energy. Broad areas of search have been identified in accordance with the now<br />

revoked NPPG 6 (Renewable Energy Developments) which will be suitable <strong>for</strong> wind and<br />

other renewable technology. An indication is also given of the areas where overriding<br />

environmental reasons would mean that development should only take place in exceptional<br />

circumstances and guidance is to be provided on the broad criteria which would apply to<br />

renewable energy projects. Policy ENVP5 (Renewable Energy) advises that the Council will<br />

prepare a policy on renewable energy in accordance with NPPG 6 and submit this as an<br />

alteration.<br />

5.3.12 Subsequent alterations led to the CSSPA, encouraging renewable energy developments in<br />

locations where there would be no significant loss of amenity, and ensuring the setting and<br />

integrity of features of importance (<strong>for</strong> their scenic, conservation and heritage value) would<br />

not be harmed. Policy ENV14: Renewable Energy and Energy – Efficient Development<br />

states:<br />

“In the interests of sustainable development the Councils and the National Park<br />

Authority will, subject to con<strong>for</strong>mity with other relevant Structure and Local Plan<br />

policies, support:<br />

- Developments required <strong>for</strong> the generation of energy from renewable sources and<br />

fuels; and<br />

- Integration of renewable energy generation and utilisation into new developments.<br />

Development proposals must demonstrate that energy conservation and efficiency are<br />

integral to the design, and to the layout of new buildings making references to other<br />

environmental policies [ENV 2-6] and the key principles of sustainability”.<br />

Carron Valley Wind Farm<br />

5.3.13 The CSSPA also recognises the importance of wind energy technology but also seeks to<br />

protect specific landscape features and settings of natural and cultural heritage assets from<br />

adverse impacts. Of particular concern are the cumulative impacts of wind farms. Policy<br />

ENV16 advises on the principles against which the strategic location and design will be<br />

assessed:<br />

“For overriding landscape character, built heritage and natural heritage conservation<br />

reasons, siting of wind turbines will not normally be acceptable in National Scenic<br />

Areas, in Green Belts or in the areas shown on the Structure Plan Renewable Energy<br />

Supplementary Key Diagram as ‘Exclusion Areas’. These areas are:<br />

- The Ochil Hills escarpment;<br />

- The Touch – Gargunnock – Fintry Hills escarpments (including Lewis Hill);<br />

- The Campsie Fells escarpments;<br />

- Queen’s View ( Auchineden);<br />

- Kippen Muir view;<br />

- The settings of Abbey Craig - Wallace Monument, Stirling Castle, Bannockburn<br />

Memorial and battlefield, and Sheriffmuir battlefield; and<br />

- Flanders Moss.<br />

The remainder of the Structure Plan area is regarded as an ‘area of search’ <strong>for</strong><br />

development opportunities.<br />

Within the ‘area of search’, it will be <strong>for</strong> Local Plans, the National Park Plan and<br />

Supplementary Advice to set out all relevant consultation requirements and<br />

constraints. Local Plans will also further define the ‘Exclusion Areas’ and give guidance<br />

regarding development opportunities in ‘buffer zones’ around National Scenic Areas.”<br />

5.3.14 The proposed wind farm is within an “Area of Search” as shown in the Renewable Energy<br />

Supplementary Key Diagram of the CSSPA.<br />

5.3.15 In the SCLP the Council strongly supports the principle of exploiting sustainable and<br />

renewable energy resources. Policy E10 of the SCLP rein<strong>for</strong>ces this support <strong>for</strong> such<br />

developments if they accord with other policies in the Plan and they avoid significant adverse<br />

impacts.<br />

5.3.16 For larger scale wind farms, like Carron Valley, there will be a presumption in favour of<br />

development within areas of defined countryside provided the following criteria are met:<br />

• The siting and external appearance of apparatus have been chosen to minimise the<br />

impact on amenity, while respecting operational efficiency;<br />

• The development will not result in unacceptable intrusion into the landscape;<br />

• Access <strong>for</strong> construction and maintenance traffic can be achieved without<br />

compromising highway safety or causing unacceptable permanent and significant<br />

change to the environment;<br />

• The development will have no significant detrimental effect on any designated heritage<br />

feature, including Listed buildings, Conservation Areas, Ancient Monuments, Historic<br />

Gardens and Designed Landscapes, Areas of Great Landscape Value and National<br />

Scenic Areas;<br />

• The development will not affect the amenities of neighbouring occupiers unacceptably<br />

by reason of noise, visual dominance, shadow flicker, reflected light or other emission;<br />

• No electromagnetic disturbance is likely to be caused by the proposal to any existing<br />

transmitting or receiving system or (where such disturbances may be caused) that<br />

measures will be taken to remedy or minimise any such interference;<br />

• A realistic means of achieving the removal of any apparatus when redundant and the<br />

restoration of the site are proposed;<br />

• No wind turbines should interfere with authorised aircraft activity or with the known<br />

regular flight paths of birds, particularly protected migratory species.<br />

Stirling Council Supplementary Planning Guidance – Wind Turbines (March<br />

2011)<br />

5.3.17 In March 2011, Stirling Council resolved to adopt (with amendments) Planning Policies and<br />

Guidance on renewable energy (wind turbine) developments. The Council’s intention was<br />

that the policies contained within the Supplementary Planning Guidance - Interim Locational<br />

Policy and Guidance <strong>for</strong> Renewable Energy Developments - Wind turbines (SPG) were to be<br />

a material consideration <strong>for</strong> the determination of relevant planning proposals, pending<br />

inclusion in the new Local Development Plan (LDP). The status of this policy guidance<br />

remains uncertain in the context of the ongoing debate in the Council regarding the<br />

representations made to the LDP regarding wind turbine development. There is a need <strong>for</strong><br />

full Council to consider all the issues to include the implications of the SPG. The<br />

Development Plan policies prevail in this case, free from uncertainty.<br />

5.3.18 The policy framework applies to all wind turbine proposals. For the purposes of the guidance<br />

classifications of turbines are given within Table 5.4.<br />

5.3.20 In general, outwith areas of significant protection the policy approach supports proposals <strong>for</strong><br />

wind turbines where they meet a set of criteria. The proposals at Carron Valley fall within an<br />

area of Significant Protection (Policy Map 1 South) which contradicts the provisions of the<br />

Development Plan. In these circumstances wind farms will be assessed in accordance with<br />

the following provisions of Policy (1)(b):<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

• Technical and planning criteria established through national planning policy and<br />

guidance, principally the SPP and PAN 45 (now revoked);<br />

• Locational and design guidance issued by SNH;<br />

• All relevant environmental protection policies in the Development Plan;<br />

• The landscape and visual impact criteria addressed in Policy 2 and any issues of<br />

cumulative impact identified in accordance with Policy 3; and<br />

• Local technical, planning and environmental criteria as set out in the associated<br />

Guidance.<br />

5.3.21 The Stirling administrative area possesses a landscape of a high quality. To protect this<br />

resource the Council’s Policy (2) considers the capacity of the landscape to be limiting with<br />

regard to large and very large turbines. The proposals are <strong>for</strong> turbines that fall into the very<br />

large classification.<br />

5.3.22 Policy (3) addresses cumulative impact. All wind farms proposals will be assessed in relation<br />

to wind turbines established, approved, or the subject of valid undetermined planning<br />

applications. New proposals that will have an adverse impact on the natural or historical<br />

heritage resources of the area, because of cumulative or ecological impact, will not normally<br />

be acceptable. When considering cumulative impact the colour, design, layout, scale and/or<br />

proportions of new proposals relative to existing turbines will be taken into account. Discrete<br />

wind farms will not be supported around existing wind farms within the zones on Policy Map<br />

1. Cumulative impact is to be assessed under the terms of SNH guidance a summary of<br />

which is given below.<br />

5.3.23 Community benefit will not be taken into consideration in the Development Management<br />

process. Policy (6) encourages developers to liaise with the Council in order to establish any<br />

“spin-offs” <strong>for</strong> the local economy.<br />

5.3.24 The SPG sets out local guidance and criteria advising that proposals within or outwith<br />

identified areas will be assessed on their merits. The factors relevant and which act as a<br />

guide are:<br />

• Appropriate scale, design and layout <strong>for</strong> the location;<br />

• Relativity to historic environment;<br />

• Avoiding adverse impacts on wildlife and habitats of international, national and regional<br />

importance;<br />

• Avoiding construction and operational impacts on the water environment;<br />

• Protection of aviation and telecommunications interests;<br />

• Avoidance of significant detrimental effects upon nearby residential amenity (visual<br />

intrusion, noise, TV/Radio/Telecommunications interference, shadow flicker); and<br />

• Other concerns to local communities including safety concerns, traffic impact, grid<br />

connection type and routes, ancillary works.<br />

5.3.25 At a recent meeting of the Stirling Council, a report submitted by the Head of Economy,<br />

Planning & Regulation described the consultation process undertaken on the Draft Proposed<br />

Local Development Plan published in October 2011 and a summary of the representations<br />

received to the Draft Plan.<br />

Carron Valley Wind Farm<br />

5.3.26 The representations submitted regarding the wind energy policy were summarised as follows:<br />

“too restrictive as it relies on the landscape study, which was not subject to appropriate<br />

consultation be<strong>for</strong>e being adopted with the interim Wind Turbines policy. Study<br />

requires to be reviewed and updated. Interim policy is also potentially out of date as it<br />

was adopted after online government guidance was issued which updated the<br />

approach to preparing spatial frameworks.”<br />

5.3.27 The representations received will now be considered by the Local Development Plan Group<br />

and used to in<strong>for</strong>m the officials during the preparation of the proposed LDP. The intention is<br />

to submit a report to the Council at its meeting in August 2012. There remains uncertainty<br />

with regard to the finalised policy position of Stirling Council (wind turbines).<br />

Landscape and Countryside<br />

5.3.28 Policies ENV2, ENV4, ENV5, ENVP1, ENVP3, ENV7, ENV9 of the CSSP provide the<br />

necessary background to allow the development process to be in<strong>for</strong>med of the means in<br />

which to protect and enhance the landscape character of the area.<br />

5.3.29 Policy ENV2 sets out guidelines <strong>for</strong> limiting the extent of development in National Scenic<br />

Areas and advises that development in Areas of Great Landscape Value (AGLV) will only be<br />

permitted where it does not affect the overall quality of the landscape and meets the terms of<br />

Policy ENV3 (Development in the Countryside). Proposal ENVP1 and POL.E13 of the<br />

SCLP advises that the Council will be reviewing their landscape designations.<br />

5.3.30 There is a presumption against developments in National Scenic Areas unless related to the<br />

rural economy or are in the national interest or locational requirements cannot be satisfied<br />

elsewhere and the overall integrity of the designation is not compromised with strict control<br />

exercised over siting, design and landscape treatment.<br />

5.3.31 Policy POL.E15 of the SCLP makes a presumption against development in AGLV’s with the<br />

exception of activities related to the rural economy. Other developments will be permitted<br />

where their locational requirements cannot be met elsewhere with strict control over siting,<br />

design and landscape treatment. Renewable energy developments are not normally favoured<br />

but may be permitted subject to rigorous assessment and con<strong>for</strong>mity with high environmental<br />

standards.<br />

5.3.32 The CSSP also recognises the importance of preventing “sprawl” into the countryside and the<br />

importance of imposing strict controls. Policy ENV4 seeks to establish the principle of a new<br />

Green Belt designation which will be taken <strong>for</strong>ward through the Development Plan. In theses<br />

areas development will only be permitted in exceptional circumstances. The Carron Valley<br />

Wind Farm does not lie within a Green Belt or a National Scenic Area.<br />

5.3.33 The SCLP Policy POL.E7 relates to development proposals falling within countryside policy<br />

boundaries. Favourable consideration will be given to developments, which are essential to<br />

the proper functioning of the primary rural activities, or other uses which can be shown to<br />

have an overriding need <strong>for</strong> a countryside location. Such developments will be subject to<br />

further assessment in relation to traffic generation and access, services, pollution, and<br />

potential conflict with established neighbouring users.<br />

5.3.34 The key principles of sustainability are embraced in Policy ENV5 of the CSSP with the<br />

intention of achieving environmental and community benefits. The Council expect<br />

environmental enhancement to be part of any new development proposals with particular<br />

attention given to environmental features.<br />

5.3.35 In an attempt to assimilate, new development into the landscape Policy POL.E6 of the SCLP<br />

encourages developers to include proposals <strong>for</strong> significant structural planting. In the case of<br />

larger sites, which may be developed over a number of years, advanced planting may be<br />

requested all bringing about environmental enhancement in accord with the CSSP.<br />

5.3.36 As part of the enhancement and protection of the countryside the CSSP presumes against<br />

the loss of prime agricultural land unless, through the provisions of Policy ENV7.<br />

5.3.37 The SCLP Policy POL.E1 also provides protection <strong>for</strong> agricultural land and sets out criteria:<br />

a) a general presumption against development which would result in the loss of prime<br />

quality agricultural land;<br />

b) resist development proposals, which would threaten the viability of agricultural units;<br />

c) seek, where necessary, to negotiate environmentally satisfactory developments when<br />

notified of building proposals which are exempt from planning control.<br />

5.3.38 Recognition is given to the importance of <strong>for</strong>estry to the rural economy, landscape quality,<br />

recreation and biodiversity. Despite <strong>for</strong>estry being mostly outwith the control of the planning<br />

system the Councils aim is to provide strategic guidance in the revised Policy ENV8<br />

(CSSPA). This supports the development of <strong>for</strong>estry and woodland which is consistent with<br />

the Indicative Forestry Strategy (IFS) and guidance from Forestry Commission Scotland<br />

where they;<br />

• Are consistent with the objectives and targets specified in the LBAPs and other<br />

supplementary guidance; prepared by the Loch Lomond and Trossachs National Park<br />

Authority, Stirling and Clackmannanshire Councils.<br />

• Accord with the key strategic aims of the appropriate landscape character area as<br />

defined by the landscape character assessments.<br />

• Enhance the landscape setting of settlements, industry and transport corridors as well<br />

as improve the landscape, nature conservation and recreational value of degraded<br />

landscapes and Greenbelt.<br />

• Enhance native woodland, riparian woodland and sites contained in the Inventory of<br />

Gardens and Designed Landscapes.<br />

• Promote sustainable <strong>for</strong>est and woodland based recreation and public access<br />

including agricultural diversification.<br />

• Create new woodland in and around settlements.<br />

5.3.39 The proposed wind farm avoids the sensitive areas identified by the IFS. The Landscape and<br />

Visual Assessment section of the <strong>ES</strong> (Chapter 9 Landscape and Visual Assessment)<br />

contains detailed in<strong>for</strong>mation regarding minimising impact on these and other countryside<br />

resources.<br />

5.3.40 Policy ENV9 of the CSSP makes reference to the commitment of the Local Authorities to<br />

river catchment-based planning initiatives. The precautionary principle will be adopted<br />

toward flooding with a presumption against development in flood risk areas unless the<br />

flooding can be mitigated. Sustainable Urban Drainage Systems (SUDS) are promoted to aid<br />

flood control. Developers are expected to adopt the SUDS principles and in doing so realise<br />

opportunities <strong>for</strong> ecological enhancement. Policy ENV9 also rein<strong>for</strong>ces the CSSP approach<br />

to water resource management.<br />

5.3.41 The SCLPA proposes to adopt a precautionary planning policy, with site-specific guidelines<br />

based upon a 'risk framework' when dealing with flooding. The criteria contained in Policy<br />

E61 are applicable to the Carron Valley site as follows:<br />

• The Council will require the submission of a flood risk assessment in relation to any<br />

development proposal in a location where it considers (or is advised by SEPA) that any<br />

part of the site may be liable to flooding, or where development may lead to, or<br />

exacerbate, flooding elsewhere.<br />

• Development will not normally be permitted where a site-specific flood risk assessment<br />

indicates that:<br />

a) the location is part of a functioning river flood plain, or is otherwise at risk of<br />

inundation because of its relation to contours, flood defences, or tidal waters; or<br />

b) the nature of the proposal is such that increased surface-water run-off may cause<br />

or exacerbate flooding elsewhere; or<br />

c) the ecological value of affected wetlands and related habitats will be unacceptably<br />

reduced.<br />

• Exceptionally, where the flood risk is shown to be low, development or redevelopment<br />

may be permitted contrary to part 2(a) if:<br />

a) the proposal is sufficiently important to warrant specific flood alleviation or<br />

defence measures; or<br />

b) the proposal is of such a nature that people, and the structural integrity of<br />

buildings and other features, will not be at risk should flooding occur; and<br />

c) the developer bears all costs of providing and maintaining flood defences and<br />

flood warning measures.<br />

5.3.42 The Council requires flood risk assessments to be undertaken and they should be of a scope<br />

appropriate to the site and nature of development. More details of the flood risk assessment<br />

are contained within the Chapter 13 Hydrology, Hydrogeology and Ground Conditions.<br />

5.3.43 Policy E62 of the SCLPA states that the design of all developments, the aim normally should<br />

be to retain the surface water discharge from the area of the site at or below the development<br />

levels. SUDS will be fundamental to this approach (see PAN 61).<br />

Cultural Heritage<br />

5.3.44 The CSSP advises of the inextricable link between the natural and the built environment and<br />

the importance of protecting and enhancing the areas cultural heritage. This policy section<br />

makes reference to the now revoked NPPG 5 and NPPG 8 as the documents providing<br />

framework <strong>for</strong> the management of these valuable resources, including ancient monuments,<br />

listed buildings and conservation areas. Policy ENV6 seeks to ensure that these resources<br />

are protected and enhanced and that all new development respects the character and quality<br />

associated of the area.<br />

5.3.45 There are eight policies in the SCLP which are relevant to the built environment and these<br />

are summarised in Table 5.5.<br />

Natural Heritage and Biodiversity<br />

5.3.46 The area contains many designations with valued habitats and species. Policy ENV1 of the<br />

CSSP sets out criteria to protect and conserve wildlife habitats and other natural features.<br />

Development that has an adverse impact will not be permitted unless it can be proven that<br />

the designation and overall integrity of any area will not be damaged. All development<br />

proposals will be considered in the context of the findings of the Local Biodiversity Action<br />

Plans.<br />

5.3.47 The SCLP identifies the hierarchy of special area designations that contribute to nature<br />

conservation. As defined by Policy POL.E54 The Council will not normally permit or approve<br />

developments or land use changes which may adversely affect:<br />

d) the wildlife interest and conservation management of Local Nature Reserves, nonstatutory<br />

and community nature reserves and fully defined Wildlife Sites; or<br />

e) the integrity or continuity of the landscape features listed below, which are of major<br />

importance <strong>for</strong> wild fauna and flora. Where the reasons in favour of a development<br />

clearly outweigh the desirability of retaining the feature(s), mitigating measures,<br />

including replacement habitat creation will be sought on land within the developers’<br />

control. The features included are linear tree belts, shelterbelts and hedgerows;<br />

plantations and policy woodlands; semi-natural and ancient woodlands; river and<br />

estuary corridors; lochs, reservoirs and ponds; marshland; stone dykes.<br />

5.3.48 Policy POL.E55 of the SCLP addresses the remainder of the hierarchy and advises that:<br />

f) New development will not be acceptable where it is likely to have a significant adverse<br />

effect on the integrity of a Special Protection Area, Special Area of Conservation, or<br />

g) Development will not normally be acceptable which is likely to affect an SSSI or NNR,<br />

unless it can be demonstrated that it will not have a significant effect on the special<br />

interest of the site.<br />

Communities<br />

5.3.49 The strategy of the CSSP rein<strong>for</strong>ces need to care <strong>for</strong> the environment, provide appropriate<br />

development and improve quality of life. Conserving the features that contribute to local<br />

distinctiveness, including the setting of settlements needs to be addressed. Policy ENV3<br />

restricts development to those that need a countryside location and respect and preserve all<br />

features contributing to local character. The policy framework of the CSSP seeks to restrict<br />

rural development and protects the environment from adverse impacts with Policy ED4<br />

focussing development in towns and villages. With operations in the housing market<br />

indicating that a large proportion of people buy housing in rural areas of Stirling Policies H4,<br />

H5 and H6 establish criteria <strong>for</strong> controlling housing in the rural villages, the Upland Area and<br />

in the countryside generally.<br />

5.3.50 The SCLP strategy rein<strong>for</strong>ces this strategic approach seeking to ensure that the needs of all<br />

communities are met and the quality of life of local residents is enhanced. The protection of<br />

landscape and landscape setting of towns and villages will be secured by ensuring that<br />

development does not compromise the environment. Policy POL.E7 seeks to control<br />

development in the countryside not associated with rural economic activities being subject to<br />

assessment regarding traffic impact, accessibility, pollution and potential conflict with<br />

neighbouring users. Policy POL.H8 sets out siting and design criteria in accordance with<br />

national guidance PAN 36 and PAN 44.<br />

Recreation and Tourism<br />

5.3.51 The importance of tourism to inward investment is rein<strong>for</strong>ced through the provisions of Policy<br />

T1 of the CSSP with an emphasis placed on promoting a sustainable approach to tourism<br />

with Proposal TP1 recognising the need <strong>for</strong> joint working in this respect.<br />

5.3.52 The SCLP recognises that tourism is likely to be the mainstay of economic growth. Policies<br />

POL. B19 and POL.B20 support proposals <strong>for</strong> tourist and recreational facilities which are<br />

sensitively located and appropriately designed with the Housing Development in the<br />

Countryside section of the SCLP rein<strong>for</strong>cing the approach to maintaining very strict approach<br />

to new buildings in rural areas, including tourist facilities.<br />

5.3.53 Countryside is closely related to many aspects of tourism and to environmental concerns.<br />

The Stirling administrative area has substantial and varied resources which need to be<br />

managed to avoid conflicts and impacts on the environment. Policies POL.C1 and POL.C2<br />

seek to maintain and secure access and the importance of recreation on rivers and lochs is<br />

rein<strong>for</strong>ced in Policy POL.C4, POL.C5 and POL.C6.<br />

Economic Development<br />

5.3.54 Policy ED3 of the CSSP provides a framework to ensure major business and industrial uses<br />

are appropriately located where they are outwith the strategic framework of major economic<br />

development sites.<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

5.3.55 Recognition is given to the importance of traditional rural activities in the economy; and the<br />

importance of a framework to support these industries and to allow diversification, which is a<br />

priority in the Stirling countryside.<br />

5.3.56 There is an emphasis on a flexible approach to rural development, including technologybased<br />

employment, with support given where the proposals are of a scale and nature which<br />

is consistent with the natural and built environment. A more constrained approach is<br />

advocated to sensitive landscape areas. Policy ED4 of the CSSP provides the general<br />

framework <strong>for</strong> rural development which is rein<strong>for</strong>ced through the SCLP.<br />

5.3.57 The SCLP Policies POL.B6, POL.B22 and POL.B26 are applicable. Stirling District is<br />

overwhelmingly rural in character dominated by traditional rural activities. To promote rural<br />

employment opportunities Policy B6 encourages businesses which are complementary to<br />

the primary rural activities. The Council also supports farm diversification proposals provided<br />

that the new use is ancillary to the primary function as a farm (Policies POL.B22 and<br />

POL.B26) provided other SCLP policies are not prejudiced.<br />

5.3.58 Reconciling job creation with maintaining the character, quality and distinctiveness of the<br />

countryside is an aim of Policy ED7 of the SCLPA (Economic Opportunities outwith the<br />

villages and Rural Activity Areas). This policy contains criteria applicable to the Carron Valley<br />

Wind Farm as follows:<br />

• Outwith settlements and the identified Rural Activity Areas, economic development will<br />

be tightly controlled and restricted to that which is of a scale and nature consistent with<br />

the pattern of existing development, the landscape character and the natural and<br />

cultural heritage of the area.<br />

• Exceptionally, developments which demonstrate a particular need to be located in the<br />

countryside and/or a demonstrable benefit to the rural economy, which would not<br />

otherwise be achieved within the existing settlement pattern or within the Rural Activity<br />

Areas, may be permitted.<br />

• Development should not result in noise, light or other <strong>for</strong>ms of pollution which will<br />

detract from the rural character of the environment.<br />

• Development should be easily and safely accessed from the main road network (Class<br />

A or B, excluding those which are single track); or should have a negligible traffic<br />

impact.<br />

• Developers will be expected to meet other infrastructure and servicing requirements.<br />

• In assessing such applications, the Council will have particular regard to the<br />

cumulative impact of development and to the application of appropriate design,<br />

locational and environmental criteria.<br />

• Intensification of existing development will only be considered where it does not<br />

conflict with the above.<br />

Transport and Access<br />

5.3.59 The transport policies of CSSP promote a sustainable approach and seek to provide better<br />

links with land use planning. Policy TR1 provides <strong>for</strong> an integrated approach to land use and<br />

transport which will be implemented through the CSLP. The strategy is aimed at creating<br />

new opportunities <strong>for</strong> effective traffic management and improvements. The Policy places an<br />

emphasis on; reducing the need to travel; improve transport choice and accessibility;<br />

ensuring developers are responsible <strong>for</strong> transport assessments and mitigation of adverse<br />

impacts; and reducing environmental impact (noise, air and congestion).<br />

5.3.60 Policy TR2 promotes a wider choice of transport requiring:<br />

• Developers to ensure that developments integrates and where possible enhances the<br />

transport network;<br />

• Contribution to the cost of providing and operating public transport;<br />

• Encouraging a shift from road borne to rail freight;<br />

• Integration between transport modes;<br />

• A reduction in the use of Trunk Roads and other routes <strong>for</strong> short journeys.<br />

5.3.61 The development of strategic transport infrastructure including; walking and cycling routes<br />

with linkages to local networks; and the provision of strategic transport infrastructure (Stirling<br />

- Alloa – Kincardine railway and upgrading of the A907 and the Upper Forth Crossing) is<br />

promoted through Proposal TRP1 of CSSP.<br />

5.3.62 The approach is reflected in the SCLP showing how the strategic aims are to be<br />

implemented. This advocates that there is a redirection of investment to schemes which<br />

reduce dependence upon road traffic by promoting other <strong>for</strong>ms of transport. The Council will<br />

support proposals which do not adversely affect traffic flows (POL.T1) and does not affect<br />

strategic opportunities (POL.T2). Policy POL.T3 supports the principle of a comprehensive<br />

transport system which will:<br />

• Assist in easing congestion and allow the fullest degree of mobility <strong>for</strong> residents; and<br />

• In the interests of energy conservation and improved accessibility will encourage future<br />

land use proposals to be located where they represent an extension to existing<br />

development.<br />

5.3.63 Long distance cycleway and footpath development is promoted and to be safeguarded from<br />

unacceptable <strong>for</strong>ms of development as the Council apply sustainable principles to transport.<br />

Policies POL.T4 and POL.T5 sets out how this is to be achieved.<br />

5.3.64 Policies POL.T9 and POL.T10 identifies the provisions of social inclusion requiring access<br />

<strong>for</strong> disabled persons to be available in new and existing developments, new routes and<br />

amenities. The Design and Access <strong>Statement</strong> accompanying the planning application<br />

addresses social inclusion.<br />

5.4 Other Material Considerations<br />

National Planning Framework 2<br />

5.4.1 National Planning Framework 2 (NPF2) was approved by the Scottish Parliament in 2009 and<br />

sets out the national spatial strategy <strong>for</strong> Scotland’s development to 2030. Core parts of the<br />

strategy relate to the realisation of the potential of Scotland’s renewable energy resources.<br />

Paragraph 155 states that “the Government is committed to establishing Scotland as a<br />

leading location <strong>for</strong> the development of renewable energy technology and an energy exporter<br />

over the long term. The aim of national planning policy is to develop Scotland’s renewable<br />

energy potential whilst safeguarding the environment and communities.”<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

Scottish Planning Policy (SPP)<br />

5.4.2 SPP was published in February 2010 and is a statement of Scottish Government policy on<br />

land use planning. The SPP subject policies on renewable energy (paragraphs 182 to 195)<br />

set out how the planning system should manage the process of encouraging, approving and<br />

implementing renewable energy proposals when preparing development plans and<br />

determining planning applications.<br />

5.4.3 Paragraph 182 outlines the Scottish Ministers’ commitment to increasing the amount of<br />

electricity generated from renewable sources in response to climate change and the need to<br />

ensure and diversify energy supplies. It identifies that Scottish Ministers have set a target of<br />

generating 50 % (this target has now been increased to 100 %) of Scotland’s electricity from<br />

renewable sources by 2020 and confirms that this target should not be regarded as a cap.<br />

5.4.4 The intention of the SPP is that this renewable energy target should be met by a range of<br />

renewable technologies. However, this paragraph recognises that onshore wind power is<br />

currently making the most significant contribution and that this is expected to continue in the<br />

short to medium term.<br />

5.4.5 Paragraph 187 establishes that planning authorities should support the development of wind<br />

farms in locations where the technology can operate efficiently and cumulative impacts can<br />

be satisfactorily addressed. It provides that development plans should provide a clear<br />

indication of the potential <strong>for</strong> development of wind farm of all scales, and should set out the<br />

criteria that will be considered in deciding applications <strong>for</strong> all wind farm developments. It<br />

states that the criteria will vary depending on the scale of the development and its<br />

relationship to the characters of the surrounding area, but are likely to include:<br />

• Landscape and visual impact;<br />

• Effects on the natural heritage and historic environment;<br />

• Contribution of the development to renewable energy generation targets;<br />

• Effect on the local and national economy and tourism and recreation interests;<br />

• Benefits and dis-benefits <strong>for</strong> communities;<br />

• Aviation and telecommunications;<br />

• Noise and shadow flicker, and<br />

• Cumulative impact.<br />

5.4.6 Paragraph 188 clarifies that when considering cumulative impacts, planning authorities<br />

should take account of existing wind farms, those which have permission and valid<br />

applications <strong>for</strong> wind farms which have not been determined. The weight that planning<br />

authorities attach to undetermined applications should reflect their position in the application<br />

process.<br />

Scottish Government On-Line <strong>Renewables</strong> Advice<br />

5.4.7 In February 2011, the Scottish Government introduced the first tranche of web based<br />

renewables advice which replaces PAN 45 – Renewable Energy Technologies (revised in<br />

2002) and its supporting Annex 2: Spatial Frameworks (2008). The on-line advice is intended<br />

to be more succinct and to provide a user-friendly resource offering guidance on new<br />

technologies and processes, with clarification of the roles of planning authorities, consultees<br />

and developers in enabling development.<br />

5.4.8 The guidance provides that the suggested areas of focus <strong>for</strong> planning authorities should<br />

include:<br />

• “Providing greater clarity on where groups of wind turbines can be located by ensuring<br />

that a spatial framework <strong>for</strong> wind farms >20 MW has been set out in the development<br />

plan and addressing the potential below 20 MW where appropriate;<br />

• Detailing criteria to be applied in assessing wind turbine applications; and<br />

• Ensuring that planning conditions and agreements <strong>for</strong> wind turbine approvals are<br />

reasonable and proportionate.”<br />

5.4.9 In considering the landscape impacts of wind farms when determining planning applications,<br />

the guidance recognises that the receiving landscape features and the design of the<br />

development can play a significant role in ensuring the proposals are integrated into the<br />

landscape setting. It states that “the ability of the landscape to absorb development often<br />

depends largely on features of landscape character such as land<strong>for</strong>m, ridges, hills, valleys<br />

and vegetation. This can also be influenced by careful siting and the skills of the designer.”<br />

5.4.10 In relation to the impacts on wildlife and habitats, the guidance, although recognising the<br />

potential <strong>for</strong> adverse impacts, also identifies the beneficial effects that wind farm proposals<br />

may have. It states that “Wind turbine developments have the capacity to have both positive<br />

and negative effects on the wildlife, habitats, ecosystems and biodiversity of an area. For<br />

example, the effects of climate change are known to have damaging effects on wildlife,<br />

habitats, ecosystems and biodiversity, and the production of renewable energy counters this.<br />

There are also many opportunities <strong>for</strong> wind turbine developments to introduce environmental<br />

improvement through land management, land restoration and habitat creation, as part of a<br />

development scheme.”<br />

5.4.11 Other criteria identified in the guidance to be assessed in the determination of wind farm<br />

proposals include impacts on communities (shadow flicker, noise, electromagnetic<br />

interference and ice throw), aviation and other defence matters, road traffic impacts and<br />

cumulative impacts.<br />

PAN 60 - Planning <strong>for</strong> Natural Heritage<br />

5.4.12 PAN 60 does not specifically address wind farm developments but does provide general<br />

guidance on the siting and design of development in relation to Scotland’s natural<br />

environment.<br />

5.4.13 The general principle, as stated in paragraph 52, is that ‘while inappropriate development can<br />

detract from scenic quality or adversely affect particular habitats, species or earth heritage<br />

interests, well designed and carefully sited development can complement the landscape and<br />

substantially increase natural heritage interest’. NPPG 14 (now revoked) stresses that the<br />

scale, siting and design of new development should take full account of the character of the<br />

landscape and the potential impact on the local environment (paragraph 15) (now<br />

encompassed within Paragraph 127 in the SPP). Landscape character assessment can play<br />

a valuable role in in<strong>for</strong>ming the development of a policy framework <strong>for</strong> the siting and design of<br />

new development.<br />

PAN 1/2011 – Planning and Noise<br />

5.4.14 PAN 1/2011 provides guidance on how noise issues should be considered and addressed in<br />

relation to development proposals; including the use of planning conditions relating to noise.<br />

5.4.15 With regard to wind farms, Paragraph 29 states that “good acoustical design and siting of<br />

turbines is essential to minimise the potential to generate noise.”<br />

Stirling Council Local Development Plan<br />

5.4.16 At present Stirling Council is preparing the Local Development Plan under the requirements<br />

of the Planning etc (Scotland) Act 2006. The Council approved the Main Issues Report (MIR)<br />

<strong>for</strong> consultation in April 2010. The Council has reported representations to the Draft<br />

Proposed Plan to Committee on the 1st March 2012. This included representations on the<br />

SPG on wind turbine development. The Council have asked the LDP Group to consider the<br />

representations and advise officers on the preparation of the proposed LDP which is to be<br />

considered by the Council in August 2012.<br />

5.4.17 The proposed plan will become a material consideration in the determination of this planning<br />

application.<br />

Scottish Natural Heritage Policy <strong>Statement</strong>: Strategic Locational Guidance <strong>for</strong><br />

Onshore Wind Farms (2009) & Policy <strong>Statement</strong> 01/02<br />

5.4.18 This Strategic Locational Guidance, published by Scottish Natural Heritage (SNH), whilst<br />

endorsing the importance of wind farm development as a means of addressing climate<br />

change, recognises the importance of adopting a strategic approach to reduce the potential<br />

significant impact of development on natural heritage.<br />

5.4.19 The document makes reference to the guiding principles on wind farm location, which are<br />

embodied in SNH’s Policy <strong>Statement</strong> 01/02: Renewable Energy (2001). This establishes<br />

guiding principles on the location of renewables.<br />

5.4.20 The policy takes these guiding principles and applies them across Scotland. Throughout the<br />

country SNH have identified a range of landscape and biodiversity sensitivities which are<br />

judged on the basis of the importance of the interest and the susceptibility to impact from<br />

wind farms. These are shown in a mapping <strong>for</strong>mat (Maps 1 - 5).<br />

5.4.21 Sensitivity is categorised in three broad zones as follows:<br />

• Zone 1 Lowest natural heritage sensitivity, with the greatest opportunity <strong>for</strong><br />

development.<br />

• Zone 2 Medium natural heritage sensitivity where through careful choice there is scope<br />

<strong>for</strong> development.<br />

• Zone 3 High natural heritage sensitivity.<br />

5.4.22 The detailed maps and tables within the policy statement provide guidance on where there is<br />

scope and constraint <strong>for</strong> wind farm development.<br />

Scottish Natural Heritage Guidance Assessing The Cumulative Impact Of<br />

Onshore Wind Energy Developments (2012)<br />

5.4.23 The guidance recognises the importance of addressing cumulative impacts and outlines the<br />

legislative framework within which cumulative impact requires to be addressed, including the<br />

EIA Regulations 2011.<br />

5.4.24 The guidance has due regard to the abovementioned Strategic Locational Guidance and<br />

Policy <strong>Statement</strong> 01/02 as they both point firmly to the need to take account of cumulative<br />

impact. The document gives advice on how, when and where to take account of these<br />

impacts and gives advice to decision takers and developers. SNH advises also that:<br />

“In all cases, the focus is on <strong>for</strong>ward planning: setting out the vision <strong>for</strong> windfarm<br />

development; and determining the thresholds of acceptable change, where the most<br />

suitable locations <strong>for</strong> development are, and what might be an appropriate design and<br />

scale.”<br />

5.4.25 The guidance refers to the cumulative impact of windfarm development on landscape and<br />

visual amenity as a product of:<br />

• the distance between individual windfarms (or turbines),<br />

• the distance over which they are visible,<br />

• the overall character of the landscape and its sensitivity to windfarms,<br />

• the siting and design of the windfarms themselves, and<br />

• the way in which the landscape is experienced.<br />

5.4.26 The cumulative effects on landscape, visual amenity as well as the perceived effects are<br />

topics covered within the guidance, with SNH providing recommendations on how to carry out<br />

a Cumulative Landscape Visual Impact Assessment.<br />

Forestry Commission Scotland Strategy Policies and Programmes<br />

5.4.27 The Scottish Forestry Strategy and Implementation Plan (2011-14) focuses on key<br />

priorities <strong>for</strong> the next decade so as to take <strong>for</strong>estry <strong>for</strong>ward through the first half of this<br />

century. The national <strong>for</strong>est estate recognises that there needs to be a focus on six priorities:<br />

• safeguarding ‘national <strong>for</strong>estry treasures;<br />

• delivering <strong>for</strong>estry <strong>for</strong> people and rural development;<br />

• managing landscape-scale areas <strong>for</strong> threatened species and habitats;<br />

• retaining sufficient timber production potential to help market stability and<br />

development;<br />

• using acquisition, sale or land transfer, partnerships and other arrangements to<br />

generate a greater scale and pace of change; and<br />

• sustaining sufficient regional presence to provide policy development, exemplar and<br />

leadership roles.<br />

5.4.28 To support this framework a number of policies and programmes have been developed. The<br />

Climate Change Action Plan (2006) recognises the important role of <strong>for</strong>estry in contributing<br />

to a low cost mitigation portfolio and the role of the <strong>for</strong>estry sector in helping to tackle climate<br />

change.<br />

5.4.29 Climate change is a significant driver in the Forestry Commission Scotland’s (FCS) policy<br />

“Control of Woodland Removal” (2009), setting an agenda to allow Scotland to play its part<br />

in the global debate. Woodland removal is defined as the permanent removal of woodland <strong>for</strong><br />

the purposes of conversion to another type of land use. Wind farms is one of the reasons <strong>for</strong><br />

tree loss. The document establishes a strategic framework <strong>for</strong> appropriate woodland removal,<br />

lending support to the maintenance and expansion of <strong>for</strong>est cover as a means of achieving<br />

the right balance between <strong>for</strong>ested and non-<strong>for</strong>ested areas in Scotland. Guiding principles<br />

establish the intent of FCS with criteria determining when woodland removal is acceptable<br />

and when and where it is not.<br />

5.4.30 Woodland removal, with compensatory planting, is most likely to be appropriate where it<br />

would contribute significantly to:<br />

• helping Scotland mitigate and adapt to climate change;<br />

• enhancing sustainable economic growth or rural/community development;<br />

• supporting Scotland as a tourist destination;<br />

• encouraging recreational activities and public enjoyment of the outdoor environment;<br />

• reducing natural threats to <strong>for</strong>ests or other land; or<br />

• increasing the social, economic or environmental quality of Scotland’s woodland cover.<br />

5.4.31 Other relevant policy guidance centres on working with communities, recognising the ways to<br />

deliver woodland benefits, strengthen communities and encourage active citizenship. In<br />

“Forests <strong>for</strong> People” (2008) recreational strategy document, the national <strong>for</strong>est estate is<br />

identified as a place <strong>for</strong> all types of recreation. It is an environment that contributes to active<br />

lifestyles and the improvement of wellbeing and provides opportunities <strong>for</strong> others to develop<br />

businesses. The “Woods <strong>for</strong> Health” (2009 - 2011) strategy rein<strong>for</strong>ces these benefits<br />

focussing upon the health promoting opportunities in a green environment; and the “Woods<br />

<strong>for</strong> Learning Strategy” (2009) aims to create greater awareness and use of the<br />

opportunities and benefits of learning and teaching outdoors.<br />

5.4.32 The FCS has published the Carron Valley Forest Visitor & Interpretation Plan in February<br />

2012. It is a practical guide to assist FCS deliver an improved visitor experience <strong>for</strong> all <strong>for</strong>est<br />

users. The vision is to make this area Central Scotland’s favourite <strong>for</strong>est destination<br />

indentifying an underlying need to offer a high quality experience and a management<br />

objective to maximise the quality of the experience and preserve the natural environment, in<br />

places.<br />

5.4.33 The Scottish Forestry Strategy encourages competitive and innovative business to deliver on<br />

the Governments national outcomes related to sustainable economic growth. The FCS<br />

promote this through the strategic framework “Supporting Business Development” (2009)<br />

which identifies opportunities in the <strong>for</strong>estry estate. This includes the renewables industry<br />

where a major opportunity exists <strong>for</strong> well-coordinated and strategically located projects<br />

related to wind farms and other technologies, as the task of raising profitable revenue<br />

remains a focus of FCS.<br />

5.4.34 The Framework Strategic Plan 2008 – 2013 (2008) provides more detail on some of the<br />

opportunities summarised above.<br />

Planning Policy Overview


Carron Valley Wind Farm<br />

6 Climate Change and Atmospheric Emissions<br />

6.1 Introduction and Overview<br />

6.1.1 This chapter considers the proposed wind farm in relation to the expected renewable energy<br />

generation and associated reductions in atmospheric emissions of CO 2. This chapter also<br />

considers the carbon payback associated with the proposed wind farm.<br />

6.2 Justification <strong>for</strong> the Development<br />

Current Issues<br />

Climate Change<br />

6.2.1 There is now unequivocal evidence of climate change associated with human activity, from<br />

observations of increases in global average air and ocean temperatures, widespread melting<br />

of snow and ice and rising global average sea level (Intergovernmental Panel on Climate<br />

Change, 2007). The effects of climate change are widely recognised as being one of the<br />

greatest global environmental challenges facing the world today.<br />

6.2.2 A major cause of climate change is a rise in the concentration and volume of green house<br />

gases (GHG) in the atmosphere. This increase affects the way the earth retains heat and the<br />

world’s leading environmental scientists have concluded this process is leading to an<br />

increase in the earth’s average temperature, causing climate change.<br />

6.2.3 The main human influence on global climate is emissions of key greenhouse gases,<br />

specifically: Carbon Dioxide (CO 2 ), Methane (CH 4 ) and Nitrous Oxide (N 2 O) – <strong>for</strong> ease of<br />

reference, these are generally expressed as a “carbon equivalent” – that is, equivalent tonnes<br />

of CO 2 .<br />

6.2.4 The Intergovernmental Panel on Climate Change (IPCC), a body of United Nations scientists<br />

which monitors studies examining the effects of climate change, reported an increase in<br />

atmospheric CO 2 concentration from a pre-industrial value of about 280 parts per million<br />

(ppm) to 379 ppm in 2005. About two-thirds of the observed increased atmospheric carbon<br />

concentration is believed to be due to the carbon emissions released from the burning of<br />

traditional fossil fuels (notably coal and oil), to generate power.<br />

Finite Fuel Sources<br />

6.2.5 In addition to the issue of climate change, concerns currently exist about the long-term<br />

viability of the use of fossil fuels to generate energy, due to the finite nature of the fuel. Owing<br />

to political instability, there are also concerns that too heavy a reliance on imported fuels<br />

could threaten the UK’s security of supply even in the relatively short-term future.<br />

6.2.6 The European Commission’s Green Paper: ‘Towards a European Strategy <strong>for</strong> the Security of<br />

Energy Supply’, highlights the importance of diversity of energy supply and of energy<br />

generation within the European Union, along with an emphasis on increasing energy from<br />

renewable sources (European Commission, 2000).<br />

The Advantages of Renewable Energy and Wind Power<br />

6.2.7 The primary benefits of renewable sources of energy (including wind, solar, hydro, tidal, and<br />

geothermal) to generate electricity over conventional fuels are:<br />

• Conservation of finite resources - Renewable sources of energy are those that are not<br />

based on finite reserves stored within the earth. Using wind to generate electricity is<br />

non-consumptive.<br />

• Reduction in pollutant emissions - Using wind to generate electricity produces no<br />

operational derived gases or other by-products and there<strong>for</strong>e does not contribute<br />

directly to local air pollution. In contrast, burning fossil fuels produces pollutants<br />

including oxides of nitrogen (NO X ) and sulphur dioxide (SO 2 ).<br />

• Reduction in greenhouse gas emission/energy use over the lifetime of the facility - The<br />

comparison of the energy used during the manufacture and construction of a power<br />

station or wind farm with the energy generated during its operation is known as its<br />

energy balance. The energy balance can be expressed in terms of energy “pay-back”<br />

time or carbon pay-back time, which is the time needed to generate the equivalent<br />

amount of energy/carbon used in manufacturing and constructing the facility. It is<br />

generally accepted that carrying out such a calculation indicates that wind power has a<br />

much shorter pay-back time than other non-renewable generators, typically taking only<br />

a few months of operation <strong>for</strong> a wind turbine to pay <strong>for</strong> itself in energy terms (Welsh<br />

Assembly Government, 2003). It has been estimated that the energy invested in<br />

manufacturing a wind turbine is typically paid off within less than a year of operation,<br />

though this will vary according to the nature of the site (Vestas Wind Systems, 2005).<br />

Scottish Government published a Technical Note in 2011 <strong>for</strong> calculating carbon<br />

‘payback’ times <strong>for</strong> wind farms on Scottish peatlands (Scottish Government, 2011a),<br />

following up on Nayak, Smith et al (2011) updated carbon calculator <strong>for</strong> wind farms on<br />

peat and <strong>for</strong>estry. This considers the effects of wind farms during construction and<br />

operation on soil stability and long-term greenhouse gas emissions. The estimated<br />

carbon payback time <strong>for</strong> the proposed wind farm is presented below in Section 6.5 of<br />

this chapter.<br />

• Production of a more secure and long-term energy supply (DEFRA, 2011) - wind<br />

power creates an effectively infinite source of power by harnessing energy generated<br />

from natural resources. There<strong>for</strong>e the development of a diverse range of electricity<br />

generating technologies contributes to reducing the risks related to the supply and cost<br />

of electricity.<br />

• Use of a freely available resource - Improvements in technology and rises in fossil fuel<br />

in fuel costs have resulted in the cost of wind power falling close to those of<br />

conventional sources of electricity. Wind is there<strong>for</strong>e both the most abundant and one<br />

of the cheapest of the UK's renewable energy resources (Sustainable Development<br />

Commission, 2005). As the UK is one of the windiest countries in Europe (BWEA,<br />

2005), it is well placed <strong>for</strong> the harnessing of wind energy. Scotland in particular has a<br />

significant wind resource, according to a report on the regional renewable energy<br />

assessments commissioned by the Department of Trade and Industry (OXERA, 2002).<br />

• Source of jobs - Given the recent investment into renewable energy and wind power,<br />

particularly in Scotland, the emerging sector is recognised as a growing source of jobs<br />

in the medium to long term.<br />

6.2.8 The report Scotland's Renewable Resource (Scottish Executive, 2001) considered a range of<br />

available renewable energy technologies, examining associated development constraints and<br />

costs. The key conclusion referring to onshore wind development was that the resource is<br />

widespread and is the cheapest of the technologies considered. On the basis of cost,<br />

onshore wind energy can be expected to contribute to the bulk of near-term government<br />

targets.<br />

6.2.9 There<strong>for</strong>e, wind power is considered to have many benefits over conventional energy<br />

sources.<br />

Policy Drivers <strong>for</strong> Renewable Energy Development<br />

6.2.10 In addition to these environmental and economic benefits, as discussed in Chapter 5:<br />

Planning Policy Overview renewable energy is supported by national policy (in particular the<br />

Climate Change (Scotland) Act 2009 and Scottish Planning Policy) and by a range of<br />

international and national targets.<br />

6.2.11 The EU, UK and Scottish governments have published policy and legislation to support the<br />

need to reduce carbon emissions. Details of these are provided in Chapter 5: Planning<br />

Policy Overview. A brief summary of recent policy and legislation relevant to Scotland is<br />

provided below.<br />

6.2.12 The Climate Change (Scotland) Act 2009 requires Scotland’s greenhouse gas emissions to<br />

be at least 80 % lower in 2050 compared with 1990 levels (known as the “2050 target”),<br />

including an interim target requires emissions to be 42 % lower by 2020 compared with 1990<br />

levels.<br />

6.2.13 The Scottish Government issued the Climate Change Delivery Plan, entitled ‘Meeting<br />

Scotland’s Statutory Climate Change Targets’ in June 2009. The Plan sets out the high level<br />

measures required in each sector to meet Scotland’s statutory climate change targets to<br />

2020 as set in the Climate Change (Scotland) Act 2009; and the work to be done over the<br />

next decade to prepare <strong>for</strong> the more radical changes needed by 2030 if the 80 % emission<br />

reduction target is to be achieved.<br />

6.2.14 For the electricity sector, targets have been set <strong>for</strong> the percentage of electricity demand,<br />

which requires to be obtained from renewable energy sources by 2020. The current target,<br />

which was set by the Scottish Government in May 2011, is <strong>for</strong> 100 % of Scotland’s gross<br />

annual electricity consumption to be generated from renewable sources by 2020.<br />

6.2.15 The Scottish Government issued the <strong>Renewables</strong> Action Plan (RAP) in June 2009. The RAP<br />

identifies what needs to happen in the renewables sector and by when in order to meet the<br />

Scottish Government’s renewable energy targets, with a particular focus on actions needed<br />

over the immediate 24 month period.<br />

6.2.16 The 2020 Routemap <strong>for</strong> Renewable Energy in Scotland was published in July 2011 and<br />

updates and extends the Scottish <strong>Renewables</strong> Action Plan to reflect the challenge of the<br />

Scottish Government’s new targets <strong>for</strong> renewable energy. The Routemap identifies that the<br />

Scottish Government has committed to meeting the EU’s 2020 renewable energy target of 20<br />

% by setting a new target to source 30 % of energy demand from renewables by 2020. This<br />

is further broken down into 100 % electricity; 11 % heat; and 10 % transport fuels. This 20 %<br />

target goes beyond the legally binding 15 % target that the EU has set <strong>for</strong> the UK and reflects<br />

the higher level of potential and the Scottish Government’s greater ambition <strong>for</strong> renewables in<br />

Scotland.<br />

6.2.17 SPP was published in February 2010 and is a statement of Scottish Government policy on<br />

land use planning. The SPP subject policies on renewable energy (paragraphs 182 to 195)<br />

set out how the planning system should manage the process of encouraging, approving and<br />

implementing renewable energy proposals when preparing development plans and<br />

determining planning applications.<br />

6.2.18 The UK Government and the Scottish Government are there<strong>for</strong>e committed to ensuring that<br />

an increased proportion of electricity is generated from wind power and other renewable<br />

energy sources. Government policy is to set targets <strong>for</strong> the generation of electricity from<br />

renewable energy sources by reference to the installed capacity of the proposed source of<br />

generation. Two significant targets to note are:<br />

• An interim target of a 42 % reduction in Scotland’s GHG emissions by 2020, rising to<br />

an 80 % reduction by 2050 (based on 1990 GHG emissions), as defined by the<br />

Climate Change (Scotland) Act 2009;<br />

• In May 2011 The Scottish Government set a target <strong>for</strong> the supply of 100 % (Scottish<br />

Government, 2011c) of Scotland’s electricity from renewable sources by 2020,<br />

recognising the extent of Scotland's important renewables resource.<br />

6.2.19 However, it is important to note that these targets are not fixed “ceilings”, and the Climate<br />

Change Act in particular requires frequent revisions of targets and more stringent emissions<br />

reductions over time.<br />

6.2.20 A detailed assessment of the relevant EU, UK and Scottish climate change and renewable<br />

energy policy framework is contained within Chapter 5: Planning Policy Overview and the<br />

separate supporting Planning <strong>Statement</strong> which accompanies the planning application.<br />

6.3 Methodology<br />

6.3.1 There is no specific guidance or policy <strong>for</strong> evaluating the effects of renewable energy<br />

schemes on climate change and energy generation. There<strong>for</strong>e the approach that has been<br />

adopted combines a quantitative evaluation of the operational benefits of the scheme, in<br />

terms of the anticipated electricity generation and the associated reduction in emissions of<br />

CO 2 this has the potential to avoid compared with other generation sources, with a qualitative<br />

assessment of the significance of this contribution towards meeting regional targets.<br />

6.3.2 In<strong>for</strong>mation on the average electricity usage of households is taken from the Average<br />

Scottish Domestic Electricity Sales (DECC, 2009). The conversion of this to a level of CO 2<br />

emissions avoided is made by combining the expected average annual generation of<br />

electricity from the site with a level of emissions avoidance per kWh. The CO 2 avoidance<br />

level used is that endorsed by the Advertising Standards Authority in September 2008 based<br />

on the assumption that the energy generated by the wind turbines displaces Combined Cycle<br />

Gas Turbines and an average mix generation of 430gCO 2 /kWh.<br />

6.3.3 The level of CO 2 emissions avoided is dependent on the scale of the scheme proposed. The<br />

evaluation of the benefit is presented in terms of the scheme output relative to current<br />

regional renewable energy generation targets and a subjective professional judgement<br />

applied as to whether that constitutes a significant effect.<br />

6.3.4 A carbon balance assessment has also been undertaken as part of the Assessment of<br />

Effects in accordance with the Scottish Government recommended methodology: Calculating<br />

carbon savings from wind farms on Scottish peat lands – A new approach (Nayak et al.<br />

2011).<br />

6.4 Expected Energy Yield and Associated Avoidance of Carbon Dioxide<br />

Emissions<br />

Renewable Electricity Generation<br />

6.4.1 Taking into account the candidate turbine <strong>for</strong> the site, it is expected that 15 turbines with a<br />

total installed capacity of 45 MW could generate up to 98.55 gigawatt-hours (GWh) of<br />

renewable electricity per year. This figure is based on a conservative capacity factor of 25 %<br />

(<strong>for</strong> onshore wind the five year average capacity factor 2006 – 2010 is 26.16 % (DECC, 2011,<br />

Table 7.4). These figures are derived as follows (using a 25 % capacity factor):<br />

45,000 kilowatts kW (15 × 3 MW turbine) × 8,760 hours/year × 0.25 (capacity factor) =<br />

98,550,000 kilowatt hours (kWh) or 98.55 GWh<br />

6.4.2 The Digest of UK Energy Statistics (DEC, 2011) gives 2010 domestic electricity consumption<br />

as 118, 681 (GWh) which when divided by the number of households in the UK (26,591,600<br />

households (DECC, 2010) gives an average electricity usage of 4,463 kWh per year per<br />

household in the UK (118,681,000,000 ÷ 26,591,600 = 4,463).<br />

6.4.3 Based on the 4,463 kWh household figure, and the predicted electricity generation of up to<br />

98.55 GWh, it is estimated that the yearly output from the wind turbines will be equivalent to<br />

the approximate domestic electricity needs of up to 22,081 average households in Britain<br />

(e.g. 98,550,000 ÷ 4463 = 22,081).<br />

6.4.4 In 2010, there were approximately 38,048 households in the Stirling Council area (GRO<br />

Scotland, 2010); there<strong>for</strong>e the proposed wind farm alone could supply approximately 58 % of<br />

the annual electricity demand <strong>for</strong> Stirling. This percentage may decrease slightly during the<br />

lifetime of the wind farm due to predicted population growth in Scotland as a whole.<br />

However, there is also the strong possibility that domestic electricity consumption may reduce<br />

due to energy efficiency measures that are currently being proposed by the Scottish<br />

Government (2011b). Although these figures are open to variation, in principle they show<br />

that the proposed wind farm will provide a substantial proportion of electricity used in the local<br />

area.<br />

Reductions in Atmospheric Emissions of CO 2<br />

6.4.5 It is widely accepted that electricity produced from wind energy has a positive effect with<br />

regard to reducing CO 2 emissions. In estimating the actual saving, it is important to consider<br />

the mix of alternative sources of electricity generation, <strong>for</strong> example coal powered and gas<br />

powered, and there has been much debate about the amount of CO 2 emissions that could<br />

potentially be saved as a result of switching to wind generation.<br />

6.4.6 In September 2008, the Advertising Standards Authority endorsed a figure of 430 gCO 2 /kWh,<br />

based on the assumption that the energy generated by the wind turbines displaces Combined<br />

Cycle Gas Turbines and an average mix generation (430 gCO 2 /kWh). On this basis, and on<br />

the assumption that the proposed wind energy development annual output is 98.55 GWh, a<br />

wind energy development of this scale is expected to displace approximately 42,376 tonnes<br />

of CO 2 emissions per year being emitted to atmosphere. These figures are derived as<br />

follows:<br />

98,550,000 kW (output) × 430 gCO 2 /kWh ÷ 1,000,000 = 42,376 tonnes CO 2<br />

6.5 Carbon Payback<br />

6.5.1 A key environmental benefit of the proposed Carron Valley Wind Farm is the generation of<br />

electricity from a renewable energy source that will reduce or avoid the use of fossil fuels<br />

through the displacement of electricity generated from other sources of energy.<br />

6.5.2 It is widely recognised that wind farms save carbon emissions during operation when<br />

compared to fossil fuel energy generation, as shown above. However, carbon losses and<br />

gains during the construction and operation of the wind farm need to be evaluated on a sitespecific<br />

basis.<br />

6.5.3 Protecting and retaining the substantial reserves of carbon held in Scottish soils is an issue<br />

recognised by the Scottish Government. Scottish Natural Heritage (SNH) produced a<br />

Technical Guidance Note in 2003 <strong>for</strong> calculating carbon ‘payback’ times <strong>for</strong> wind farms.<br />

Nayak et al. updated this guidance and devised a carbon balance tool <strong>for</strong> wind farms being<br />

constructed on peat and <strong>for</strong>estry which considers the effects of wind farms during<br />

construction and operation on soil stability and long-term greenhouse gas emissions.<br />

6.5.4 The carbon balance of the proposed wind farm was calculated in accordance with the<br />

Scottish Government recommended methodology: Calculating Carbon Savings from Wind<br />

Farms on Scottish Peat Lands – A New Approach (Nayak et al. 2011).<br />

6.5.5 Where possible, site-specific in<strong>for</strong>mation was used to populate the parameters of the Carbon<br />

Calculator. In order to in<strong>for</strong>m the requirement <strong>for</strong> site-specific in<strong>for</strong>mation a sensitivity<br />

analysis of each of the main parameters in the carbon calculator was undertaken. This<br />

process established which of the parameters has the greatest influence on the payback time<br />

(i.e. the most sensitive) and there<strong>for</strong>e those parameters <strong>for</strong> which it would be preferable to<br />

obtain site-specific data.<br />

6.5.6 Appendix 6.1 provides full details of the sensitivity analysis carried out <strong>for</strong> the carbon balance<br />

assessment. In some instances it was not feasible to obtain site-specific in<strong>for</strong>mation due to,<br />

<strong>for</strong> example, timescales required to obtain data. In this case publicised data was used to<br />

populate the calculator in accordance with the Carbon Payback Calculator: Guidelines on<br />

Measurements available from the Scottish Government (2011d).<br />

6.5.7 Table 6.1 shows the calculated payback time associated with the proposed wind farm. The<br />

results of the carbon calculator are presented in full within Appendix 6.2.<br />

6.5.9 This is increased to an expected 3.8 years against the grid mix of electricity generation, which<br />

includes other renewable electricity sources and the payback is decreased to an expected<br />

1.9 years compared with coal-fired electricity generation.<br />

6.5.10 It should be noted that although the CO 2 emitted during wind farm construction is taken into<br />

account in this calculation, that produced from construction of the other <strong>for</strong>ms of power<br />

stations is not – there<strong>for</strong>e, in some ways this calculation is biased against wind generation.<br />

There<strong>for</strong>e, when considering the 25 year operational period of the proposed wind energy<br />

development, the CO 2 payback time is very short in comparison.<br />

7 Traffic and Transport<br />

7.1 Introduction and Overview<br />

7.1.1 This chapter considers the likely significant effects of the proposed wind farm on the strategic<br />

and local transport network.<br />

7.1.2 The chapter describes the baseline traffic conditions which currently exist within the vicinity of<br />

the proposed wind farm and surroundings, the assessment methodology, potential traffic<br />

related effects and their significance during the construction, operation and decommissioning<br />

phases of the project, any mitigation measures required to prevent, reduce or offset any<br />

significant adverse effects identified and any likely significant effects after these measures<br />

have been implemented.<br />

7.1.3 The location of the proposed wind farm and the surrounding road network is shown on Figure<br />

7.1. It is expected that all construction traffic associated with the proposed wind farm would<br />

likely travel along the strategic road network and suitable routes including the M9, the A872<br />

and the B818. The vast majority of all construction staff would also travel along these routes.<br />

7.1.4 It is expected that the wind turbine components would travel to the proposed wind farm from<br />

Grangemouth. If Grangemouth port is not available then an alternative port could be used at<br />

Rosyth.<br />

7.1.5 The route from Grangemouth would route onto the M9 at Junction 6 from the A904 to<br />

Junction 9, turning onto the A872 and then the B818 to the site. This is essentially the same<br />

route that the adjacent Earlsburn Wind Farm utilised and is shown on Figure 7.1.<br />

7.1.6 The existing access routes would be upgraded within the site and new routes to each turbine<br />

location created where necessary (see Chapter 4: Description of the Proposed<br />

Development). During operation, the turbines would only require occasional access <strong>for</strong><br />

maintenance. The layout design <strong>for</strong> the main junction from the B818 into the site is attached<br />

at Appendix 7.1, Figure TA7.1.1.<br />

7.2 Methodology<br />

Relevant Guidance<br />

7.2.1 As a matter of best practice, this assessment has been undertaken based on current relevant<br />

guidance <strong>for</strong> assessing the environmental effects of traffic. This is set out within The Institute<br />

of Environmental Assessment (IEA) (now the IEMA) publication ‘Guidance Note Number 1:<br />

Guidelines on the Environmental Assessment of Road Traffic’, 1993.<br />

Methodology<br />

7.2.2 The IEMA Guidelines recommend two rules to be considered when assessing the impact of<br />

development traffic on a road link:<br />

• Rule 1: Include highway (road) links where traffic flows will increase by more than<br />

30 % (or the number of heavy goods vehicles will increase by more than 30 %); and<br />

• Rule 2: Include any other specifically sensitive areas where total traffic flows have<br />

increased by 10% or more.<br />

Traffic and Transport


Carron Valley Wind Farm<br />

7.2.3 The above guidance is based upon knowledge and experience of environmental effects of<br />

traffic. The 30 % threshold is based upon research and experience of the environmental<br />

effects of traffic, with less than a 30 % increase generally resulting in imperceptible changes<br />

in the environmental effects of traffic. At a simple level, the guidance considers that projected<br />

changes in total traffic flow of less than 10 % creates no discernible environmental effect,<br />

hence the second threshold as set out in Rule 2.<br />

7.2.4 In cases where the thresholds are exceeded, Column 3 in Table 2.1 of the IEMA guidelines<br />

set out a list of environmental effects which should be assessed <strong>for</strong> their magnitude of<br />

change.<br />

7.2.5 Definitions of each of the potential effects identified in the IEMA guidelines are summarised<br />

below along with explanatory text relating to assessment criteria. It is on this basis that the<br />

assessment in this Chapter has been undertaken. It is acknowledged at paragraph 2.4 of the<br />

IEMA guidelines that not all the effects listed in Column 3 of Table 2.1 would be applicable to<br />

every development. A detailed inspection of the surrounding road network incorporating the<br />

current geometric layout of the road, traffic management and regulation orders and general<br />

observations of existing road user movements has been undertaken to assist with the<br />

assessments.<br />

Noise and Vibration<br />

7.2.6 The potential effects relating to noise and vibration as a result of construction traffic and<br />

abnormal loads is set out in Chapter 8: Noise.<br />

Visual Effects<br />

7.2.7 The visual effect of traffic is complex and subjective and includes both visual obstruction and<br />

visual intrusion. The IEMA guidelines acknowledge that in the majority of situations the<br />

changes in traffic resulting from a development will have little effect.<br />

7.2.8 Concerns are also often expressed over the visual effects of the wind turbines on traffic itself,<br />

whereby drivers may be distracted by the turbines and the movement of the blades. These<br />

effects are considered in the Department <strong>for</strong> Communities and Local Government (DCLG)<br />

publication ‘Planning <strong>for</strong> Renewable Energy: A Companion Guide to PPS22’, December<br />

2004. Although this guidance document does not specifically relate to Scotland, its evidence<br />

base remains a solid area to consider the effects of ‘driver distraction’.<br />

7.2.9 The guidance document sets out that drivers are faced with a number of varied and<br />

competing distractions, such as advertising hoardings, which are deliberately designed to<br />

attract attention.<br />

7.2.10 Drivers are required to take reasonable care to ensure their own and others’ safety at all<br />

times. There<strong>for</strong>e, wind turbines should not be treated any differently from other distractions a<br />

driver must face and should not be considered particularly hazardous.<br />

7.2.11 The guidance document concludes that there are a large number of wind farms adjoining or<br />

close to road networks and there has been no history of accidents at any of them. As stated,<br />

this evidence base remains sound and, on this basis, no assessment is necessary to assess<br />

the visual effects of the wind turbines themselves upon driver distraction.<br />

7.2.12 Where relevant, the visual effects of traffic are considered within this chapter. The visual<br />

effects of the scheme as a whole are considered in Chapter 9: Landscape and Visual Impact<br />

Assessment.<br />

Severance<br />

7.2.13 Severance is the perceived division that can occur within a community when it becomes<br />

separated by a major traffic artery. The term is used to describe a complex series of factors<br />

that separate people from places and other people. Severance can also result from difficulty<br />

in crossing a heavily trafficked road (IEMA, March 1993).<br />

7.2.14 The guidance indicates that severance effects are considered ‘slight’, ‘moderate’ and<br />

‘substantial’ with changes in traffic flows of 30 %, 60 % and 90 % respectively.<br />

7.2.15 Where relevant, effects on severance are considered within this chapter.<br />

Driver Delay<br />

7.2.16 Where roads affected by new development are at or near capacity, the traffic associated with<br />

new development can cause or add to vehicle delays. Other sources of delay <strong>for</strong> nondevelopment<br />

traffic can include:<br />

• at the proposed wind farm entrance where there will be additional turning movements:<br />

• on the roads passing the proposed wind farm where there is likely to be additional<br />

traffic;<br />

• at other key intersections along the road which might be affected by increased traffic;<br />

and<br />

• at junctions where the ability to find gaps in the traffic may be reduced, thereby<br />

lengthening delays.<br />

7.2.17 Where relevant, the effects on driver delay are considered within this chapter.<br />

Pedestrian Delay<br />

7.2.18 Highly trafficked roads and changes to the volume or speed of traffic may affect the ability of<br />

people to cross roads. Studies have shown that pedestrian delay is perceptible or<br />

considered significant beyond a lower delay threshold of 10 seconds, <strong>for</strong> a link with no<br />

crossing facilities. A 10 second pedestrian delay in crossing a road broadly equates to a twoway<br />

link flow of approximately 1,400 vehicles per hour (IEMA, March 1993).<br />

7.2.19 Where relevant, the effects on pedestrian delay are considered within this chapter.<br />

Pedestrian Amenity<br />

7.2.20 The term pedestrian amenity is broadly defined as the relative pleasantness of a journey. It is<br />

considered to be affected by traffic flow, speed and composition as well as footway width and<br />

the separation/protection from traffic. It encompasses the overall relationship between<br />

pedestrians and traffic, including fear and intimidation which is the most emotive and difficult<br />

effect to quantify and assess. There are no commonly agreed thresholds <strong>for</strong> quantifying the<br />

significance of changes in pedestrian amenity, although the IEMA guidelines refers to a<br />

useful study which could be referenced when considering any effect. These thresholds are<br />

replicated in Table 7.1.<br />

7.2.21 Where relevant, the effects on pedestrian amenity are considered within this chapter.<br />

Accidents and Safety<br />

7.2.22 It is possible to estimate the effects of increased traffic on accidents and safety from existing<br />

accident records, national statistics, the type and quantity of traffic generated, journey lengths<br />

and the characteristics of the routes in question.<br />

7.2.23 Where relevant, the effects on accidents and safety are considered within this chapter.<br />

Hazardous Loads<br />

7.2.24 Some developments may involve transporting hazardous loads by road such as special<br />

wastes, toxic materials and chemicals. Where appropriate, the risks associated with<br />

accidents on such movements are identified or quantified.<br />

7.2.25 Where relevant, the effects of hazardous loads are considered within this chapter.<br />

Dust and Dirt<br />

7.2.26 Certain types of development, notably quarrying and the transport of quarried materials, can<br />

give rise to deposition of dust and dirt on surrounding roads. The overall impact of this<br />

phenomenon normally depends to a large extent on the management practices adopted at<br />

the site in question, such as vehicle sheeting and wheel washing. Problems with dust and<br />

dirt are unlikely to occur at distances greater than 50m from the road (IEMA, March 1993).<br />

7.2.27 Where relevant, the effects relating to dust and dirt are considered within this chapter.<br />

Assessment of Significance<br />

7.2.28 The approach to the assessment of significance of effects follows that as set out in Chapter<br />

2: The Environmental Impact Assessment and Scoping Process and is summarised in Table<br />

7.2 and Table 7.3 below, adapted from DMRB HA 205/08. This takes into account the<br />

duration, magnitude, direction and location of each effect as well as the sensitivity of the<br />

receptor. Where any of the above potential effects define any specific criteria to determine<br />

effects, these will be assessed in conjunction with Table 7.2 and Table 7.3 to establish the<br />

significance.<br />

Criteria<br />

Only adverse effects are assigned this level of importance as they represent key<br />

factors in the decision-making process. These effects are generally, but not<br />

exclusively, associated with sites and features of international, national or<br />

regional importance that are likely to suffer a most damaging effect and loss of<br />

resource integrity. A major change at a regional or district scale site or feature<br />

may also enter this category.<br />

These beneficial or adverse effects are likely to be very important considerations<br />

at a local or district scale and, if adverse, are potential concerns to the scheme<br />

and may become material in the decision making process.<br />

These beneficial or adverse effects while important at a local scale are not likely<br />

to be key decision making issues. Nevertheless, the cumulative effect of such<br />

issues may influence decision making if they lead to an increase in the overall<br />

adverse effects on a particular area or on a particular resource.<br />

These beneficial or adverse effects may be raised as local factors but are<br />

unlikely to be of critical importance in the decision making process. Nevertheless<br />

they are of relevance in enhancing the subsequent design of the Scheme and<br />

consideration of mitigation or compensation measures.<br />

No effect or an effect which is beneath the level of perception, within normal<br />

bounds of variation or within the margin of <strong>for</strong>ecasting error. Such effects are not<br />

normally considered by the decision maker.<br />

7.2.29 In accordance with the above IEMA guidance, the assessments are being based upon the<br />

relative change between the baseline conditions and the baseline plus development<br />

conditions. The effect along all road links of the adjacent road network where any<br />

development traffic is predicted to route along will be assessed in accordance with the above<br />

methodology.<br />

7.2.30 The proposed traffic flows associated with the construction, operation and decommissioning<br />

of the proposed wind farm are assessed against a range of local sensitive locations.<br />

7.2.31 Paragraph 2.5 of the IEMA Guidelines explains that locations which may be sensitive to<br />

changes in traffic conditions could be people at home, people in work places, sensitive<br />

groups such as children, the elderly or the disabled, sensitive locations such as hospitals,<br />

churches, schools or historical buildings, people walking or cycling, open spaces, recreational<br />

sites, shopping areas, sites of ecological/nature conservation value and sites of tourist/visitor<br />

attraction.<br />

7.2.32 As set out below, it is considered that sections of the A872 through Dunipace and Denny may<br />

be sensitive to changes in traffic conditions, as is the B818 within the built up area to the west<br />

of Denny, due to the fronting residential properties. The change in traffic flows at these<br />

sections will there<strong>for</strong>e be assessed against the ‘Rule 2’ threshold (‘include any other<br />

specifically sensitive areas where total traffic flows have increased by 10 % or more’) with the<br />

other links being assessed against the ‘Rule 1’ threshold.<br />

7.2.33 Where these thresholds are exceeded, each of the potential effects set out above will be<br />

assessed at that location to determine the magnitude of change and significance of effect, in<br />

conjuction with Table 7.2 and Table 7.3.<br />

Consultation<br />

7.2.34 A Scoping Report (RPS report ref: SAE2069) was sent out to all statutory consultees. The<br />

relevant responses from road authorities are attached at Appendix 7.2. The key transport<br />

related responses were:<br />

• Identify traffic generation during construction, operation and decommissioning;<br />

• Anticipated length of operations;<br />

• Assessment of suitable traffic routes and road network;<br />

• Proposed modifications;<br />

• Predicted effects;<br />

• Mitigation;<br />

• Development of a Traffic Management Plan; and<br />

• Section 96 of the Roads (Scotland) Act 1984 to cover any extraordinary damage to the<br />

road network.<br />

7.2.35 In addition, discussions have commenced with the road authorities on the proposed access<br />

route <strong>for</strong> abnormal loads, and at the time of submission these discussions are ongoing.<br />

7.3 Baseline In<strong>for</strong>mation<br />

Sources of Data<br />

7.3.1 The baseline transport situation has been established through obtaining traffic flows and<br />

Personal Injury Accident data from the road authorities and through a site visit to identify the<br />

location of any sensitive receptors.<br />

7.3.2 These datasets and in<strong>for</strong>mation gathered have in<strong>for</strong>med a baseline position, against which<br />

the proposals can be assessed and any significant transport effects established.<br />

plan and material considerations is contained within a separate supporting Planning<br />

<strong>Statement</strong> (PS) which accompanies the planning application.<br />

7.3.4 The below there<strong>for</strong>e sets out those relevant Development Plan documents which provide a<br />

context <strong>for</strong> undertaking EIA as part of this Chapter with relevant Policies following:<br />

• The Clackmannanshire and Stirling Structure Plan (approved 2002) (hereafter referred<br />

to as the CSSP);<br />

• The Clackmannanshire and Stirling Structure Plan Alteration (2004) (hereafter referred<br />

to as the CSSPA);<br />

• The Stirling Council Local Plan (adopted December 1999) (hereafter referred to as the<br />

SCLP); and<br />

• The Stirlingshire Council Local Plan First Alteration (2007) (hereafter referred to as the<br />

SCLPA).<br />

7.3.5 The transport policies of CSSP promotes a sustainable approach and seeks to provide better<br />

links with land use planning. Policy TR1 provides <strong>for</strong> an integrated approach to land use and<br />

transport which will be implemented through the CSLP. The strategy is aimed at creating<br />

new opportunities <strong>for</strong> effective traffic management and improvements. The Policy places an<br />

emphasis on; reducing the need to travel; improve transport choice and accessibility;<br />

ensuring developers are responsible <strong>for</strong> transport assessments and mitigation of adverse<br />

effects; and reducing environmental effect (noise, air and congestion).<br />

7.3.6 Policy TR2 promotes a wider choice of transport requiring:<br />

• Developers to ensure that developments integrates and where possible enhances the<br />

transport network;<br />

• Contribution to the cost of providing and operating public transport;<br />

• Encouraging a shift from road borne to rail freight;<br />

• Integration between transport modes;<br />

• A reduction in the use of Trunk Roads and other routes <strong>for</strong> short journeys.<br />

7.3.7 The development of strategic transport infrastructure including; walking and cycling routes<br />

with linkages to local networks; and the provision of strategic transport infrastructure (Stirling<br />

- Alloa – Kincardine railway and upgrading of the A907 and the Upper Forth Crossing) is<br />

promoted through Proposal TRP1 of CSSP.<br />

7.3.8 The approach is reflected in the SCLP showing how the strategic aims are to be<br />

implemented. This advocates that there is a redirection of investment to schemes which<br />

reduce dependence upon road traffic by promoting other <strong>for</strong>ms of transport. The Council will<br />

support proposals which do not adversely affect traffic flows (POL.T1) and does not affect<br />

strategic opportunities (POL.T2). Policy POL.T3 supports the principle of a comprehensive<br />

transport system which will:<br />

• Assist in easing congestion and allow the fullest degree of mobility <strong>for</strong> residents; and<br />

• In the interests of energy conservation and improved accessibility will encourage future<br />

land use proposals to be located where they represent an extension to existing<br />

development.<br />

Baseline Conditions<br />

Local Road Network<br />

7.3.11 The site in context to the local road network is shown on Figure 7.1. The site takes access<br />

from the B818 which routes west from Denny into rural areas towards Loch Lomond. The<br />

B818 is a single carriageway road of varying widths, geometries and speed restrictions.<br />

7.3.12 In the vicinity of the site access, the B818 is approximately 4.8m wide with grass verges on<br />

its northern and southern sides and fences set further back to delineate the road boundary.<br />

There is no street lighting and the B818 is derestricted, being subject to the national speed<br />

limit of 60mph.<br />

7.3.13 At its eastern end, the B818 routes through Stoneywood and the western fringes of Denny,<br />

has street lighting and is subject to a 30mph speed restriction. There is frontage access to a<br />

number of residential properties and no parking restrictions.<br />

7.3.14 The B818 <strong>for</strong>ms the minor arm of a ghost island right turn priority junction with the A872<br />

Nethermains Road, which routes north to south around the western fringes of Denny. At its<br />

southern end, the A872 joins with the A803 which provides links to Junction 4 of the M80 in<br />

the west and with Bonnybridge in the east.<br />

7.3.15 At the northern end of Denny, the A872 Nethermains Road becomes the A883 and continues<br />

east out of Denny towards Falkirk. The A872 Stirling Street routes north from the A872<br />

Nethermains Road / A883 ghost island priority junction through Dunipace and to Junction 9 of<br />

the M9 and Junction 6 of the M80.<br />

7.3.16 The A872 Stirling Street is an urban wide single carriageway road, a 30mph speed restriction,<br />

frontage access to a number of properties and street lighting. North of Dunipace to the M9<br />

and M80 junctions, the A872 becomes rural and is subject to the national speed limit of<br />

60mph.<br />

7.3.17 From Junction 6, the M80 routes south only towards Glasgow. The M9 routes north-west to<br />

Dunblane and south-east to Edinburgh.<br />

7.3.18 As explained below in Section 7.5, it is envisaged that construction staff vehicles and<br />

construction HGVs would utilise the above road network to access and egress the site. It is<br />

envisaged that Grangemouth Port will be used as the port of entry <strong>for</strong> the turbine<br />

components. Abnormal loads transporting these components will then route along the<br />

following sections of the road network:<br />

• Abnormal loads will access onto the A904 Earl’s Road;<br />

• Route south west onto Junction 6 of the M9;<br />

• Route north west along the M9;<br />

7.3.21 The Construction of the proposed wind farm is likely to take place <strong>for</strong> 20 months with peak<br />

activities and traffic movements during month seven. The construction of the proposed wind<br />

farm is likely to commence within the coming years. For assessment purposes, it is assumed<br />

that peak construction month (month seven) would occur during 2015. There<strong>for</strong>e, to enable<br />

the likely effects during construction to be assessed, traffic growth factors have been used to<br />

predict the growth in the base flows to this peak construction year of 2015.<br />

7.3.22 The Trip End Model Presentation Programme (TEMPRO) has been used to update observed<br />

traffic data obtained from 2010 to predict the likely level of traffic which will be using the road<br />

network in 2015.<br />

7.3.23 TEMPRO is produced by the Department <strong>for</strong> Transport (DfT) and uses a wide range of data<br />

so that accurate localised traffic growth projections can be predicted. As such the use of<br />

TEMPRO <strong>for</strong> predicting the growth in existing traffic flows <strong>for</strong> future baseline traffic<br />

Personal Injury Accident Statistics<br />

7.3.26 Personal Injury Accident (PIA) statistics have been obtained from Stirling Council and Falkirk<br />

Council, <strong>for</strong> the surrounding road network over the latest available 36 months (3 years)<br />

between 1 November 2008 and 31 October 2011. These have been plotted in terms of<br />

location and severity on Figure 7.4.<br />

7.3.27 There were twenty injury accidents during this three year period, five of which resulted in<br />

serious injury and 15 of which resulted in only slight injury. There were no fatal injury<br />

accidents. None of the injury accidents involved a HGV.<br />

7.3.28 There were no clusters of injury accidents and no common contributory factors amongst the<br />

injury accidents.<br />

7.3.29 There were only two injury accidents on the B818 between the site access and the A872, one<br />

of which resulted from a car overtaking on a bend and one resulted from a cyclist failing to<br />

give way.<br />

7.3.30 It is considered that there are no existing road safety issues along the proposed access<br />

route.<br />

In<strong>for</strong>mation Gaps<br />

7.3.31 The above data covers the proposed access route and has been obtained from Falkirk<br />

Council and Stirling Council. The data is considered to be representative and reflective of<br />

baseline conditions. It is there<strong>for</strong>e considered that there are no ‘in<strong>for</strong>mation gaps’ in the<br />

baseline data.<br />

7.4 Topic Specific Design Evolution<br />

7.4.1 A preliminary design access junction has been designed and is shown in Appendix 7.1,<br />

Figure TA7.1.1. This design has been progressed taking due consideration of the existing<br />

access track, the adjacent road boundaries, the watercourse running alongside the access<br />

road and the existing footpath routeing along the northern side of the B818.<br />

7.4.2 Visibility splays from the access are 2.4m x 90m to the left and 2.4m x 110m to the right.<br />

Given the undulating nature of the horizontal and vertical alignment of the road and given the<br />

carriageway geometrics, these visibility splays are considered suitable, particularly given<br />

these will maintain the current nature of the road and be in-keeping with its surroundings.<br />

7.4.3 The access has been designed to accommodate the swept path of the abnormal loads within<br />

the extent of surfaced road without any reliance upon any verge use and is also shown on the<br />

drawing.<br />

7.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

Effects During Construction Phase<br />

Abnormal Loads<br />

7.5.1 It is expected that abnormal loads will access the proposed wind farm from Grangemouth<br />

Port. This route has been used be<strong>for</strong>e <strong>for</strong> the delivery of abnormal loads to the operational<br />

Earlsburn Wind Farms adjacent to the site.<br />

7.5.2 An abnormal load movement is defined by Transport Scotland in the Abnormal Load<br />

Movements 2007 guide as a vehicle that has any of the following:<br />

• a weight of more than 44 tonnes;<br />

• a width of more than 2.9 metres; or<br />

• a length of more than 18.3 metres.<br />

7.5.3 Depending on the width, length or weight of the vehicle different notice periods have to be<br />

provided to the Road & Bridge Authorities and the police, this can vary between 2 and 5<br />

days.<br />

7.5.4 Some of the turbine components will qualify as abnormal loads. The vehicles used to<br />

transport turbine components would constitute abnormal loads only on the delivery phase of<br />

the journey since the extendible trailers are retracted to the size of a standard articulated<br />

vehicle (16.5 metres) during the return leg. Each delivery of turbine components there<strong>for</strong>e<br />

consists of one abnormal load movement on the inbound journey to the proposed wind farm<br />

and one articulated HGV movement on the return journey.<br />

Carron Valley Wind Farm<br />

7.5.5 It is expected that abnormal load vehicles will access the proposed wind farm from<br />

Grangemouth via the M9, the A872 and the B818, as shown on Figure 7.1 and as described<br />

below:<br />

• Abnormal loads will leave Grangemouth Port onto the A904 Earl’s Road;<br />

• Route south west onto Junction 6 of the M9;<br />

• Route north west along the M9;<br />

• Turn south onto the A872 from Junction 9 of the M9;<br />

• Route south along the A872 Stirling Street to Denny, turning right onto the A872<br />

Nethermains Road; and<br />

• Turn right onto the B818 and route west to the site access.<br />

7.5.6 At this stage, it is proposed to erect either the Vestas V90 or the Enercon E82. The Vestas<br />

V90 is the largest of the two and has the greatest transportation requirements. To represent<br />

a worst case scenario, and <strong>for</strong> the purposes of assessment, it has been assumed that the<br />

V90 would be transported to the site. A Swept Path Analysis has been undertaken in this<br />

regard and is submitted as part of this application. The vehicles used in the Swept Path<br />

Analysis are set out at Appendix 7.3.<br />

Construction Traffic and Access<br />

7.5.7 Given the layout of the adjacent road network, it is expected that all HGVs and cars<br />

associated with the construction phase would route to the proposed wind farm, via the B818<br />

from the east of the site and the A872.<br />

7.5.8 Given the accessible nature of the site, it has been assumed that one-quarter of all HGVs<br />

and construction workers would route to the site from west / south-west via the A80 / M80<br />

corridor, one-quarter would route from the east / south-east via the M9 corridor, one-quarter<br />

would route locally from the Falkirk area via the A883 and one-quarter would route from the<br />

north via the M9 corridor.<br />

7.5.9 This results in half of all vehicle movements routeing along the A872 from the M9 Junction 9<br />

and onto the B818, one-quarter routeing along the A883 from Falkirk, onto the A872 at Denny<br />

and onto the B818 and one-quarter routeing along the A803 from Junction 4 of the M80 and<br />

onto the A872 and B818.<br />

7.5.10 As set out above, a preliminary design access junction has been designed and is shown in<br />

Appendix 7.1, Figure TA7.1.1 which has taken due consideration of the existing access track,<br />

the adjacent road boundaries, the watercourse running alongside the access road, the<br />

existing footpath routeing along the northern side of the B818 and the swept path of the<br />

abnormal loads within the extent of surfaced road without any reliance upon any verge use.<br />

Construction Traffic Trip Generation<br />

7.5.11 The construction of the 15 turbines is predicted to be over a 20 month programme and is<br />

summarised in Chapter 4: Description of the Proposed Development.<br />

7.5.12 The likely traffic generation resulting from the process can be split into the following<br />

elements:<br />

• low loaders containing wind turbine components;<br />

7.5.14 The construction programme set out in Chapter 4: Description of the Proposed Development<br />

has then been used to estimate the likely traffic generated per month during the construction<br />

phase and is set out below in Table 7.7. From these monthly totals, the average number of<br />

daily vehicle movements can be calculated.<br />

Abnormal Load Trip Generation<br />

7.5.15 Turbine component deliveries are likely to take place between months 7 and 14 with a three<br />

month break during months 10 to 12. During that period up to 90 abnormal loads of wind<br />

turbine components would be delivered to the proposed wind farm, including blades, tower<br />

sections, trans<strong>for</strong>mers and nacelles <strong>for</strong> the 15 turbines.<br />

7.5.16 Based on the construction programme this equates to a maximum of 14 abnormal load<br />

deliveries per month.<br />

7.5.17 The delivery of cranes and components may or may not result in abnormal loads depending<br />

upon the crane provider. If it is assumed that the cranes do result in abnormal loads and that<br />

they are removed from site during the break period (months 10 to 12), then an additional<br />

eight abnormal load movements (four deliveries) would be generated. This scenario would<br />

increase the total number (cranes plus wind turbine components) to 98 abnormal loads.<br />

7.5.18 This assumption would increase the maximum number of abnormal loads to 16 per month.<br />

Heavy Goods Vehicle Trip Generation<br />

7.5.19 It is estimated that 896 Heavy Goods Vehicles (HGVs) will access the proposed wind farm<br />

over the entire construction period (1,792 two-way HGV movements). The construction<br />

breakdown and timeline is attached at Appendix 7.4 and shows that this equates to a<br />

maximum of three HGV arrivals per day (six two-way HGV movements per day). It is noted<br />

that the abnormal loads contract to a typical HGV size when departing the site. The inclusion<br />

of these vehicles increases the maximum number of HGV movements to seven two-way<br />

movements per day (months 7, 8 and 15).<br />

7.5.20 It is noted that rockfill is being won on the site and there will be concrete batching on the site.<br />

Both of these practices result in fewer HGV deliveries being required to the site when<br />

compared to importing all required stone and concrete to site.<br />

Carron Valley Wind Farm<br />

7.5.21 Indeed, if rockfill was not won on site and concrete batching was off site, then there would be<br />

a requirement <strong>for</strong> an approximate additional 3,000 to 4,000 HGV deliveries over the<br />

construction process, equating to approximately 6,000 to 8,000 two-way HGV movements.<br />

Construction Worker / Vans / Light Good Vehicles Trip Generation<br />

7.5.22 Over the entire construction period, it is expected that the construction process will require a<br />

total of 4,390 construction worker / van / LGV arrivals (8,780 two way vehicle movements).<br />

7.5.23 It is expected that month seven will be the peak traffic generating month of the construction<br />

process, during which time it is expected that the construction process will require 325<br />

construction worker / van / LGV arrivals. Based on a five day working week this equates to<br />

approximately 15 arrivals per day during this period (30 two-way light vehicle movements a<br />

day).<br />

Total Construction Generated Vehicles<br />

7.5.24 Table 7.7 shows the estimated daily construction traffic flows generated in line with the<br />

construction programme and based on a 5 day working week. These have been calculated<br />

by taking the maximum number of vehicle movements during a single month and calculating<br />

the average number of daily vehicle movements during this. Table 7.7 there<strong>for</strong>e sets out the<br />

number of vehicle movements on an average day during the busiest month of the<br />

construction process.<br />

7.5.25 Over the entire construction period, it is expected that the daily HGV movements (excluding<br />

abnormal loads) would be between two and seven two-way movements per working day.<br />

The number of vehicle movements generated by construction workers and vans would be<br />

between two and 30 two-way light vehicle movements per working day.<br />

7.5.26 With consideration to all vehicles, the total number of vehicle movements would be between<br />

four and 38 two-way movements per working day.<br />

Potential Significant Effects<br />

7.5.27 In terms of the thresholds outlined by the IEMA Guidelines, it suggests that traffic increases,<br />

or the number of HGVs, of less than 30 % generally results in imperceptible changes in the<br />

environmental effects of traffic. The guidance document also suggests that any specifically<br />

sensitive areas where total traffic flows have increased by 10 % or more should be<br />

considered in more detail.<br />

7.5.28 The construction traffic flows have been assigned onto the network in accordance with the<br />

distribution above (Construction Traffic and Access) and the maximum number of daily<br />

construction vehicle movements are set out in Table 7.8.<br />

7.5.30 Table 7.9 shows that the percentage increases as a result of the construction vehicles along<br />

the A872 and along the B818 in western areas of Denny are all well within the IEMA<br />

thresholds and the construction traffic generated by the proposals will there<strong>for</strong>e result in<br />

imperceptible effects.<br />

7.5.31 Indeed, the maximum predicted increase in total vehicles along the A872 is predicted to be to<br />

the south of Roman Road where an increase of 0.3 % is predicted over a 12 hour daily<br />

period. The corresponding increase in HGV movements at this location is only 1.19 %.<br />

7.5.32 The predicted 12 hour and 24 hour increases along the rural sections of the B818 to the west<br />

of Denny <strong>for</strong> total vehicles are all well within the IEMA thresholds which would indicate that<br />

the construction traffic generated by the proposals would result in imperceptible effects.<br />

Indeed, the maximum increase in total vehicles in these locations is predicted to the east of<br />

the site access where an increase of 10.8 % is predicted.<br />

7.5.33 However, it is noted that the HGV increases along the rural sections of the B818 exceed the<br />

thresholds. This is due to the very low number of HGV movements within the baseline<br />

scenario.<br />

7.5.34 For example, there are two HGV movements along the B818 to the east of the site access<br />

over a 12 hour period in the baseline scenario. An increase of only one HGV movement<br />

would there<strong>for</strong>e result in an increase of 50 %.<br />

7.5.35 In such instances, the percentage increases are misleading and the absolute numbers should<br />

be considered.<br />

7.5.36 The proposals are predicted to result in a maximum increase of eight two-way HGV<br />

movements along the B818 over the construction daytime working period, typically an eight to<br />

ten hour period ranging between 07:00 and 17:00. This equates to approximately one HGV<br />

movement per hour associated with the construction process along the rural sections of the<br />

B818.<br />

7.5.37 Such increases are low, particularly when considered against the total increase in vehicle<br />

movements where a maximum increase of 10.8 % is predicted over a 12 hour day. In this<br />

context, it is considered that the HGV movements generated during the construction phase<br />

would not result in any significant environmental effects.<br />

7.5.38 In accordance with the IEMA guidance, it is there<strong>for</strong>e considered that the construction traffic<br />

generated by the proposals would result in a negligible magnitude of change. In accordance<br />

with Table 7.2, the significance of effect would be negligible.<br />

7.5.39 Although the above has set out that the traffic generated during the construction phase would<br />

not result in any significant environmental effects, it is noted that the movement of abnormal<br />

loads sometimes requires separate consideration.<br />

7.5.40 In order to ensure a robust assessment, it is there<strong>for</strong>e considered appropriate to consider the<br />

possible effects of the abnormal loads below. Given that the above assessments shows<br />

there would be no significant effects as a result of the total construction traffic, and that the<br />

Swept Path Analysis, which accompanies this application, shows that the abnormal loads can<br />

be accommodated on the existing road network, the effects below have been considered in<br />

general terms along the entirety of the access route. This consideration is not necessary but<br />

is provided <strong>for</strong> completeness.<br />

• Disruption and driver delay – Any effects of delay to other road users would only be<br />

apparent during the movement of abnormal loads as a result of their large size and low<br />

speed rather than their numbers. The A872 and B818 are single carriageway roads,<br />

the police and any other escort personnel would ensure that driver delay is minimised<br />

by identifying locations ahead of the abnormal load where it could stop safely to allow<br />

vehicles to pass. There would be 90 abnormal loads over the entire turbine delivery<br />

period and ef<strong>for</strong>ts will be made to undertaken these outside of peak traffic hours in<br />

order to prevent any disruption or delay during these periods.<br />

It is considered that some driver delay could occur as a result of the abnormal loads,<br />

however the temporary nature and safe escorting of vehicles should be borne in mind.<br />

It is considered that the magnitude of change would be small to medium and the<br />

significance of effect of disruption and driver delay as a result of the abnormal loads<br />

upon receptors along the route would be slight to moderate.<br />

• Increased risk of accidents - There is a potential <strong>for</strong> effects on safety as a<br />

consequence of driver frustration related to the movement of abnormal loads.<br />

However, all abnormal loads will be under police escort who will be there not only to<br />

assist the abnormal loads but to control any oncoming vehicles or vehicles following<br />

the abnormal load. On this basis, driver frustration should be minimised and the risk of<br />

accidents reduced. It is there<strong>for</strong>e considered any magnitude of change would be<br />

negligible and the significance of effect of accidents and safety as a result of the<br />

abnormal loads upon receptors along the route would be negligible.<br />

• Severance, Intimidation and Pedestrian Delay - An increase in vehicle numbers,<br />

particularly HGVs through towns and villages, could result in additional delays to<br />

pedestrians wishing to cross the road i.e. severance. HGV traffic, particularly<br />

abnormal loads, can reduce the amenity of pedestrian routes in towns and villages to<br />

the extent that pedestrians feel intimidated by the traffic.<br />

There would be 90 abnormal loads which could result in intimidation or pedestrian<br />

delay, however, these movements would be spread over the construction period and<br />

any effect would be infrequent. On this basis, it is there<strong>for</strong>e considered any magnitude<br />

of change would be negligible and the significance of effect of severance, intimidation<br />

and pedestrian delay as a result of the abnormal loads upon receptors along the route<br />

would be negligible.<br />

• Dust and dirt - HGVs have the potential to distribute dust and dirt from the proposed<br />

wind farm construction site onto the local road network and is mostly pronounced in<br />

the immediate vicinity of proposed wind farms access. All access roads would<br />

constructed and surfaced in an appropriate manner and, combined with on-site<br />

construction management, it is there<strong>for</strong>e considered any magnitude of change would<br />

be negligible and the significance of effect of dust and dirt as a result of the abnormal<br />

loads upon receptors along the route would be negligible.<br />

• Visual effects - the movements of high-sided vehicles during the construction period<br />

could be considered visually intrusive. Any effect would be short-term and only occur<br />

during the movement of abnormal loads.<br />

In terms of driver distraction relating to the movement of abnormal loads, such loads<br />

would not be travelling at any great speed and drivers within their proximity would likely<br />

slow down, and on occasion even stop, whilst passing. Given these reduced vehicle<br />

speeds, it is considered that the effect of driver distraction relating to the movement of<br />

abnormal loads would not result in any road safety concerns. It is there<strong>for</strong>e considered<br />

any magnitude of change would be negligible and the significance of effect as a result<br />

of the abnormal loads upon receptors along the routes would be negligible.<br />

Summary of Construction Effects<br />

7.5.41 The maximum number of vehicle movements generated during the construction of the<br />

proposed turbines over a day is estimated at 38 two-way movements per day, eight of which<br />

will be HGVs.<br />

7.5.42 The greatest increase in total traffic is predicted to be on the B818 to the east of the site<br />

access where an increase of 10.8 % on the 12 hour baseline flows is predicted. In<br />

accordance with the IEMA guidance, the traffic generated during the construction phase<br />

along the adjacent road network is likely to result in a negligible magnitude of change and the<br />

significance of effect would be negligible.<br />

7.5.43 Notwithstanding this conclusion, consideration has also been given to the movement of<br />

abnormal loads. This assessment showed that the movement of abnormal loads is generally<br />

likely to result in a negligible magnitude of change and the significance of effect would be<br />

negligible, with the exception of disruption and driver delay where the magnitude of change<br />

would be small to medium and the significance of effect would be slight to moderate.<br />

Effects During Operation Phase<br />

7.5.44 During the operational phase of the development, there will be no permanent staff based at<br />

the wind farm and only the occasional routine maintenance which is carried out using a 4x4<br />

vehicle will be generated to the site. It is there<strong>for</strong>e not considered necessary to assess the<br />

environmental effects of the traffic generated by the operational phase of the proposed wind<br />

farm.<br />

7.5.45 As above, the evidence base which in<strong>for</strong>med the DCLG publication ‘Planning <strong>for</strong> Renewable<br />

Energy: A Companion Guide to PPS22’, December 2004, has in<strong>for</strong>med the conclusion that<br />

drivers would not be distracted by the turbines or the movement of the blades.<br />

Effects During Decommissioning Phase<br />

7.5.46 The levels of traffic associated with decommissioning are anticipated to be similar or lower<br />

than those required during construction there<strong>for</strong>e the construction phase assessment of<br />

effects is broadly relevant to that <strong>for</strong> decommissioning.<br />

7.6 Mitigation and Enhancement Measures<br />

7.6.1 Although the above assessments demonstrate that there is no requirement <strong>for</strong> any mitigation<br />

measures, a Traffic Management Plan (‘TMP’) will be drawn up and agreed with the Road<br />

Authority as an enhancement measure prior to construction. The TMP will provide the<br />

following in<strong>for</strong>mation:<br />

• approved access routes and any necessary restrictions;<br />

• temporary signage in the vicinity of the proposed wind farm warning of construction<br />

traffic;<br />

• temporary signage warning other users of abnormal load turbine movements;<br />

• arrangements with Police <strong>for</strong> escort of abnormal loads;<br />

• ground preparation, including protection of services;<br />

• arrangements <strong>for</strong> road maintenance and cleaning;<br />

• timing of deliveries – construction hours will be outside of peak traffic hours, subject to<br />

agreement with the road authorities; and<br />

• wheel cleaning arrangements and regular road sweeping runs.<br />

7.6.2 Abnormal loads will be escorted, from the port of entry (currently envisaged being<br />

Grangemouth) with timings agreed with the road authorities and police as appropriate.<br />

7.6.3 These measures will assist in minimising any environmental effects associated with the<br />

construction traffic generated by the proposed wind farm.<br />

7.6.4 In order to further reduce traffic effects associated with the construction of the proposed wind<br />

farm, construction personnel will be encouraged to car-share where practicable.<br />

7.6.5 The assessment has considered each construction worker arriving at the proposed wind farm<br />

in an individual vehicle. This is considered a robust assessment as construction personnel<br />

typically show car occupancy levels of greater than one person per vehicle.<br />

7.7 Assessment of Residual Effects<br />

7.7.1 Although the enhancement measures described above are not required to reduce the level of<br />

significance with respect to the effects identified, they are included as measures to manage<br />

and control the residual effect resulting from HGV deliveries and abnormal loads. Table 7.10<br />

7.7.2 This Chapter of the <strong>ES</strong> concludes that the environmental effect of the construction of the<br />

proposed wind farm would be negligible and would be further minimised with appropriate<br />

traffic management.<br />

7.8 Cumulative Effects<br />

7.8.1 Any major developments in the area or along the access route that may arise at the same<br />

time as construction of the wind farm could result in a cumulative increase in traffic flows on<br />

the routes. In this regard, it is noted that the increases resulting from the construction of the<br />

wind farm results in only small increases relative to the baseline traffic flows which results in<br />

negligible. Indeed, if the above development traffic flows were doubled, the increase would<br />

still not exceed the thresholds identified by the IEMA and such an increase would still result in<br />

negligible effects.<br />

7.8.2 In terms of the movement of abnormal loads, such movements from any other development<br />

would not occur at the exact same time and location as those <strong>for</strong> Carron Valley. There<strong>for</strong>e,<br />

there would be no cumulative assessment in relation to these.<br />

7.8.3 It is also noted that the above is based upon the single month which generates the largest<br />

number of construction vehicles. During other months, the number of vehicles generated will<br />

be far less.<br />

7.8.4 On this basis, there is an opportunity <strong>for</strong> other wind farm developments to proceed and<br />

generate traffic similar to the above and the resultant cumulative effect would be negligible.<br />

Furthermore, given the temporary nature of the construction effect it is unlikely that the peak<br />

construction traffic above would coincide with another development and there<strong>for</strong>e no<br />

significant cumulative effect should be <strong>for</strong>thcoming.<br />

7.8.5 It should also be noted that the local access roads, once off the strategic road network, is<br />

specific to each wind farm and not every site will generate construction traffic along those<br />

assessed above.<br />

8 Noise<br />

8.1 Introduction and Overview<br />

8.1.1 This chapter assesses the potential noise and vibration effects of the proposed wind farm<br />

with respect to construction, operation and decommissioning.<br />

8.1.2 The chapter describes the methods used to assess the baseline conditions currently existing<br />

within the study boundary and surroundings, likely construction and operational noise and<br />

vibration effects, any mitigation measures required to prevent, reduce or offset any significant<br />

adverse effects predicted, and the significance of any residual effects after these measures<br />

have been employed.<br />

8.1.3 A glossary of noise and vibration technical terms is presented in Appendix 8.1. Background<br />

in<strong>for</strong>mation on wind turbine noise is provided in Appendix 8.2.<br />

8.2 Methodology<br />

Construction Noise and Vibration Significance<br />

8.2.1 Potentially noisy activities related to wind farm site construction include ripping of borrow pits,<br />

<strong>for</strong>mation of access tracks, crane pads, the construction compound and turbine foundations,<br />

erection of turbines, site cabling and installation of the substation building/trans<strong>for</strong>mer.<br />

8.2.2 Potential effects of construction noise and vibration have been considered with reference to<br />

the guidance set out in British Standard (BS) 5228.<br />

Operational Noise Significance<br />

8.2.3 Operational noise will affect the closest properties to the wind farm more than those further<br />

away. Generally speaking, operational noise is not perceptible at distances greater than 2 km<br />

from a wind turbine. Properties identified within 2 km of the proposed wind farm have<br />

there<strong>for</strong>e been considered in this assessment; however, the assessment has also given<br />

consideration to more distant properties where relevant.<br />

8.2.4 For the purposes of this assessment the following significance criteria have been adopted:<br />

• Predicted scheme or cumulative wind turbine noise levels that comply with the ETSU-<br />

R-97 derived limits are considered not to be significant;<br />

• Predicted scheme or cumulative wind turbine noise levels that exceed the ETSU-R-97<br />

derived limits are considered to be significant.<br />

8.2.5 Only those likely effects considered significant are material to this assessment.<br />

8.2.6 Potential effects of operational vibration have been scoped out of this assessment.<br />

8.3 Baseline<br />

Consultations<br />

8.3.1 A scoping opinion was sought from Stirling Council and direct communication was made with<br />

the presiding Environmental Health Officer (EHO) to agree suitable locations <strong>for</strong> baseline<br />

noise monitoring (see Table 8.1).<br />

Policy and Guidance<br />

Planning Policy and Legislative Context<br />

8.3.2 The following policy and guidance documents have been referred to <strong>for</strong> the purposes of this<br />

assessment:<br />

• The Control of Pollution Act 1974, Part III;<br />

• Environmental Protection Act 1990;<br />

• Planning Advice Note (PAN) 1/2011;Planning and Noise;<br />

• Scottish Government Factsheet Onshore Wind Turbines;<br />

• The Working Group on Noise from Wind Turbines The Assessment & Rating of Noise<br />

• British Standard 5228 (2009) Code of practice <strong>for</strong> noise and vibration control on<br />

construction and open sites Part 1: Noise and Part 2: Vibration.<br />

8.3.3 These documents are described in more detail below.<br />

Legislation<br />

The Control of Pollution Act 1974, Part III<br />

8.3.4 The Control of Pollution Act 1974 (COPA) is specifically concerned with the control of noise<br />

pollution. Section 60, Part III of COPA refers to the control of noise on construction sites. It<br />

provides legislation by which local authorities can control noise from construction sites to<br />

prevent noise disturbance occurring. In addition, it recommends that guidance provided by<br />

BS 5228 be implemented to ensure compliance with Section 60.<br />

8.3.5 Section 61, Part III of the COPA refers to prior consent <strong>for</strong> work on construction sites. It<br />

provides a method by which a contractor can apply <strong>for</strong> consent to undertake construction<br />

works in advance. If consent is given, and the stated method and hours of work complied<br />

with, then the local authority cannot take action under Section 60.<br />

8.3.6 Section 72, Part III of COPA refers to best practicable means (BPM). COPA defines BPM as<br />

“reasonably practicable, having regards among other things to local conditions and<br />

circumstances, to the current state of technical knowledge and to the financial implications’”<br />

Whilst “Means” includes “the design, installation, maintenance and manner and periods of<br />

operation of plant and machinery, and the design, construction and maintenance of buildings<br />

and acoustic structures”.<br />

Environmental Protection Act 1990<br />

8.3.7 The Environmental Protection Act 1990 (EPA) deals with statutory nuisance, including noise.<br />

Section 79, Part III of EPA places a duty on local authorities to regularly inspect their areas to<br />

detect whether a statutory nuisance exists. This section also considers and defines the<br />

concept of ‘Best Practicable Means’ which originates in Section 72, Part III of the COPA<br />

where practicable is defined as “reasonably practical having regard, among other things, to<br />

local conditions and circumstances, to the current state of technical knowledge and to the<br />

financial implications”.<br />

8.3.8 Section 80, Part III of EPA outlines the summary of proceedings <strong>for</strong> statutory nuisances.<br />

Under Section 79, the local authority must take such steps, as are reasonably practicable, to<br />

investigate any complaints of statutory nuisance within the area. Where the local authority is<br />

satisfied that a statutory nuisance does exist, or is likely to occur or reoccur, it must serve an<br />

abatement notice requiring the abatement of the nuisance or prohibiting or restricting its<br />

occurrence or recurrence, and/or the carrying out of such works or other action as maybe<br />

necessary to abate the nuisance.<br />

Guidance<br />

Planning Advice Note (PAN) 1/2011 Planning and Noise<br />

8.3.9 This Planning Advice Note provides advice on the role of the planning system in helping to<br />

prevent and limit the adverse effects of noise. In<strong>for</strong>mation and advice on noise impact<br />

assessment methods is provided in the associated Technical Advice Note Assessment of<br />

Noise.<br />

8.3.10 With regard to wind turbines, the document states: “There are two sources of noise from wind<br />

turbines - the mechanical noise from the turbines and the aerodynamic noise from the blades.<br />

Mechanical noise is related to engineering design. Aerodynamic noise varies with rotor<br />

design and wind speed, and is generally greatest at low speeds. Good acoustical design and<br />

siting of turbines is essential to minimise the potential to generate noise. Web based<br />

planning advice on renewable technologies <strong>for</strong> Onshore wind turbines provides advice on<br />

‘The Assessment and Rating of Noise from Wind Farms’ (ETSU-R-97) published by the<br />

<strong>for</strong>mer Department of Trade and Industry [DTI] and the findings of the Sal<strong>for</strong>d University<br />

report into Aerodynamic Modulation of Wind Turbine Noise.”<br />

Scottish Government Factsheet - Onshore Wind Turbines<br />

8.3.11 Scottish Government in<strong>for</strong>mation and planning advice on the technologies <strong>for</strong> renewable<br />

energy is available in the <strong>for</strong>m of a series web-based factsheets. The document Onshore<br />

Wind Turbines is of relevance to this assessment.<br />

8.3.12 In respect of noise, the document states: “The Report, ‘The Assessment and Rating of Noise<br />

from Wind Farms’ describes a framework <strong>for</strong> the measurement of wind farm noise, which<br />

should be followed by applicants and consultees, and used by planning authorities to assess<br />

and rate noise from wind energy developments, until such time as an update is available.<br />

This gives indicative noise levels thought to offer a reasonable degree of protection to wind<br />

farm neighbours, without placing unreasonable burdens on wind farm developers, and<br />

suggests appropriate noise conditions.”<br />

8.3.13 Accordingly ETSU-R-97 has been used <strong>for</strong> this assessment.<br />

The Working Group on Noise from Wind Turbines The Assessment & Rating of Noise<br />

from Wind Farms (ETSU-R-97)<br />

8.3.14 ETSU-R-97, published in September 1996, was the result of deliberations of the Working<br />

Group on Noise from Wind Turbines, which was set up in 1993 by the Department of Trade<br />

and Industry (DTI) to derive guidelines <strong>for</strong> assessing noise from wind turbines. ETSU-R-97 is<br />

Carron Valley Wind Farm<br />

the assessment method stipulated in the Scottish Government planning advice and recently<br />

the UK government has reaffirmed that noise from wind farms should be assessed according<br />

to the ETSU-R-97 guidance.<br />

8.3.15 ETSU-R-97 provides a method <strong>for</strong> assessing wind turbine noise and, in particular, <strong>for</strong> setting<br />

external noise limits to protect residential amenity and prevent sleep disturbance. The limits<br />

are either: 5dB above the prevailing background noise L A90,10min ; or fixed, at an absolute level,<br />

when background noise levels are otherwise very low. The higher of the two limits applies,<br />

and the limits will vary with wind speed. In most cases the absolute part of the limit applies at<br />

low wind speeds and the relative part, prevailing background level plus 5dB, applies at higher<br />

wind speeds. The limits are set relative to the prevailing background noise levels determined<br />

during quiet daytime periods (as defined in ETSU-R-97) and night time periods, (11 pm to 7<br />

am).<br />

8.3.16 The prevailing background noise level across the relevant range of wind speeds is<br />

determined as the best-fit regression curve when the measured background noise values, in<br />

10-minute periods (L A90,10min ), are plotted against concurrent average wind speed<br />

standardised to 10 m above local ground height, also in 10-minute periods.<br />

8.3.17 The quiet daytime periods are chosen to reflect times when people might be outside in their<br />

gardens and are defined as:<br />

• All weekday evenings from 6 pm to 11 pm;<br />

• Saturday afternoon and evenings from 1 pm to 11 pm; and<br />

• All day Sunday 7 am to 11 pm.<br />

8.3.18 For the quiet daytime periods, the suggested external noise limits across the range of wind<br />

speeds are 35 - 40 dB L A90,10min or 5 dB(A) above the prevailing background, whichever is the<br />

greater. A degree of judgement is required to determine the lower fixed limit within the 35 -<br />

40 dB L A90,10min range and ETSU-R-97 suggests that this should depend on:<br />

• The number of dwellings in the neighbourhood of the wind farm;<br />

• The effect of noise limits on the number of kWh generated; and<br />

• The duration and level of exposure.<br />

8.3.19 For the purposes of this assessment, a quiet daytime fixed limit of 35dB L A90,10min has been<br />

selected. This limit, although derived only from data obtained during the quiet periods defined<br />

above, applies throughout the entire day: 7 am to 11 pm.<br />

8.3.20 For night-time periods, the lower fixed noise limit across the range of wind speeds is 43 dB<br />

L A90,10min or 5 dB(A) above the prevailing background level, whichever is the greater.<br />

8.3.21 ETSU-R-97 allows <strong>for</strong> an increased lower fixed limit where residents are financially involved<br />

with the wind farm development. The suggested lower fixed limit is 45 dB L A90,10min <strong>for</strong> both<br />

the quiet day and night-time periods and ETSU-R-97 goes on to say that consideration<br />

should be given to increasing the permissible margin above background..<br />

8.3.22 Where audible tones are present in the wind turbine noise spectrum, ETSU-R-97<br />

recommends that a tonal penalty be added, based on the level of the tone above the masking<br />

noise. Modern wind turbines do not usually have significant tonal characteristics because<br />

noise control techniques have improved, particularly in reducing noise from gearboxes.<br />

Prediction and Assessment of Wind Turbine Noise – Agreement about Relevant<br />

Factors <strong>for</strong> Noise Assessment from Wind Energy Projects<br />

8.3.23 In the March/April 2009 issue of Acoustics Bulletin, published by the Institute of Acoustics<br />

(IOA), several noise consultants working on wind farm developments <strong>for</strong><br />

developers/applicants, local authorities and other groups agreed various particulars to<br />

standardise noise assessments. The article clarified three main issues:<br />

• That baseline noise measurements are correlated with the derived wind speed at 10 m<br />

height in preference to measured 10 m values so that wind shear on the site is taken<br />

into account;<br />

• ISO 9613-2 is to be used <strong>for</strong> wind farm predictions, with certain stipulations and<br />

limitations;<br />

• Research into low frequency noise, infrasound and vibration was summarised, and it<br />

was concluded that none of these issues have had adverse effects on wind farm<br />

neighbours.<br />

8.3.24 The article should be regarded as a refinement of the ETSU-R-97 guidance to ensure<br />

consistency and this noise assessment follows the guidelines stated therein. The article is<br />

not official IOA guidance. For brevity, it will be referred to as the Acoustics Bulletin article in<br />

this assessment.<br />

British Standard 5228 (2009) Code of practice <strong>for</strong> noise and vibration control on<br />

construction and open sites Part 1: Noise and Part 2: Vibration<br />

8.3.25 BS 5228 Part 1: Noise and Part 2: Vibration provides guidance, in<strong>for</strong>mation and procedures<br />

on the control of noise and vibration from construction sites. In its previous versions the<br />

Standard, in its various parts, was adopted under s71 of COPA.<br />

8.3.26 There are no set standards <strong>for</strong> the definition of the significance of construction noise and<br />

vibration effects. Whilst BS 5228 does not promote specific limits <strong>for</strong> construction noise, it<br />

does provide a number of example limits at Annex E of Part 1. The assessment of whether<br />

changes in noise levels due to construction constitute significant effects will be dependent on<br />

the absolute levels of ambient and construction noise, as well as the magnitude, duration,<br />

time of occurrence and frequency of the noise change. BS 5228 does, however, provide<br />

guidance on controlling, predicting and measuring noise and vibration.<br />

8.3.27 BS 5228 includes a comprehensive best practice guide to minimising the adverse effects of<br />

noise and vibration from construction sites and a database of plant and activity noise levels<br />

<strong>for</strong> undertaking predictive assessments.<br />

Baseline Conditions<br />

Description of Local Noise Environment<br />

8.3.28 Potential noise sensitive receptors (NSRs) within 2 km of the proposed wind farm have been<br />

identified, through examination of Ordnance Survey mapping and confirmed through noise<br />

contour modelling and site visits. Two properties beyond this distance were also initially<br />

identified as potential receptors but not considered to be NSRs on the basis of their distance<br />

from the nearest turbine (see Table 8.1 and Figure 8.1).<br />

8.3.29 Of the 11 potentially sensitive receptors initially identified, two were considered to be too<br />

distant from the nearest proposed turbine to be NSRs and two were subsequently found to be<br />

derelict. As a result, a total of seven NSRs have been taken <strong>for</strong>ward and three of these were<br />

selected as representative locations at which to conduct baseline noise monitoring.<br />

8.3.30 None of the NSRs are considered to be financially involved in relation to the proposed wind<br />

farm development.<br />

Baseline Noise Monitoring<br />

8.3.31 Baseline noise monitoring was conducted at three locations (see Table 8.1), in accordance<br />

with the methodology described in ETSU-R-97 and with reference to the supplementary<br />

guidance in the Acoustics Bulletin article. Selection of baseline noise monitoring locations<br />

was in<strong>for</strong>med by the production of an initial noise contour map from the SoundPLAN<br />

electronic noise model, site visits, professional judgement, and consultation with the presiding<br />

EHO prior to noise monitoring being carried out.<br />

8.3.32 Baseline noise surveys were carried out at:<br />

• NSR 3 – Craigannet (January 2012);<br />

• NSR 5 - Easter Clingate (January 2012 and March 2012); and<br />

• NSR 10 – Todholes Farm (January 2012).<br />

8.3.33 Further investigation into the Easter Clingate data sets revealed the potential <strong>for</strong><br />

contamination from the existing operational wind farms to the northeast (Craigengelt) and<br />

west (Earlsburn). Filtering of the data set to isolate south-westerly wind measurements only,<br />

thus minimising the potential <strong>for</strong> contribution from the operational wind farms, resulted in a<br />

data set considered inadequate <strong>for</strong> the purposes of this assessment.<br />

8.3.34 As a precautionary approach, the data set gathered at Todholes Farm has been adopted as<br />

representative of baseline conditions at Easter Clingate and Cairnoch Lodge <strong>for</strong> the purposes<br />

of this assessment. Todholes Farm has been selected over Craigannet as a proxy location<br />

<strong>for</strong> these two NSRs as it has the lower measured baseline noise levels, resulting in a more<br />

stringent assessment.<br />

8.3.35 The noise surveys were carried out using Rion NL-31 Class 1 Sound Level Meters (SLMs)<br />

which were installed complete with full environmental protection kits. The calibration of each<br />

SLM was checked using a 01dB calibrator be<strong>for</strong>e and after monitoring and no significant<br />

deviations were found (less than 0.2dB). The Rion NL-31 sound level meters incorporate a<br />

large wind shield which is approximately 240 mm in diameter and is there<strong>for</strong>e ideally suited to<br />

wind farm noise monitoring.<br />

8.3.36 The following section describes each noise monitoring location. All monitoring locations were<br />

positioned in the property’s main amenity area as indicated by the householder, where<br />

possible. Appendix 8.5 presents photographs of the equipment in situ at the two monitoring<br />

locations which have been used <strong>for</strong> the purposes of this assessment. No further in<strong>for</strong>mation<br />

is provided <strong>for</strong> the noise surveys at Easter Clingate which are not utilised further within the<br />

assessment (see paragraph 8.3.33 above).<br />

NSR 3 - Craigannet<br />

8.3.37 The survey was set up in the garden to the east of the residential building, at a height of<br />

1.5 m above local ground level and in a free-field position (at least 3.5 m away from any<br />

reflecting surfaces excluding the ground, consistent with the advice contained within ETSU-<br />

R-97).<br />

8.3.38 Noise monitoring equipment was located in a position representative of where the residents<br />

spend the majority of their time outdoors, as indicated by the resident. Sound levels were<br />

measured from 12 January to 25 January 2012. During the installation and removal of the<br />

monitoring equipment, some livestock noise, farm vehicles and general wildlife noise were<br />

audible.<br />

NSR 10 – Todholes Farm<br />

8.3.39 The survey was set up in the garden to the south of the residential building, at a height of<br />

8.3.40 Noise monitoring equipment was located in a position representative of where the residents<br />

Meteorological Data<br />

8.3.41 ETSU-R-97 requires correlation of the individual L A90,10min measurements with the concurrent<br />

standardised average 10 minute wind speed at a height of 10 m to determine prevailing<br />

background noise levels.<br />

8.3.42 A 70 m high anemometry mast was erected in the vicinity of the proposed wind turbines to<br />

monitor wind speed and direction.<br />

8.3.43 A wind shear analysis has been undertaken by RPS to derive standardised 10 m high wind<br />

speed data (refer to Appendix 8.4 <strong>for</strong> technical details of the wind shear assessment). This<br />

analysis has been undertaken with reference to the guidance set out in the Acoustics Bulletin<br />

article. The 10 minute average wind speed at proposed turbine maximum hub height (85 m)<br />

was calculated using the ratio of wind speeds measured simultaneously at anemometer<br />

heights of 30 m and 70 m on the anemometry mast. A standardised extrapolation to 10 m<br />

was subsequently undertaken using a standard roughness length of 0.05 m. It should be<br />

noted that the relative heights of the anemometers in relation to maximum hub height do not<br />

match exactly the requirements of the methodology set out in the Acoustics Bulletin article,<br />

which requires one anemometer to be at 40-50 % of hub height and a second at greater than<br />

60 % hub height. It is considered however that the calculation undertaken provides adequate<br />

assessment of any local wind shear effects, given the in<strong>for</strong>mation available. The full<br />

procedure <strong>for</strong> wind shear analysis is included within Standard IEC-61400-11 Wind turbine<br />

generator systems – Part 11: Acoustic noise measurement techniques.<br />

Baseline Noise Levels<br />

8.3.44 Table 8.2 summarises the results of the baseline noise monitoring undertaken at Craigannet<br />

and Todholes Farm. The data summarises the range of wind speeds and background noise<br />

data measured.<br />

8.3.45 ETSU-R-97 suggests that atypical data points should be removed from the scatter plot prior<br />

to ascertaining the best fit line which is representative of prevailing background during quiet<br />

day and night time periods.<br />

8.3.46 Atypical data may include ‘periods of significant rainfall’ or points which sit outwith the main<br />

body of data <strong>for</strong> no apparently obvious reason – this may have been due to other noise<br />

events in the acoustic environment of the monitoring location which are sporadic and do not<br />

<strong>for</strong>m part of the typical environment (e.g. car engine idling / grass cutting / persistent alarm<br />

etc.). This is common in such long unattended surveys.<br />

8.3.47 Obvious outliers have been removed from the data sets gathered at the two remaining<br />

monitoring locations, although it should be noted that occasional data points outwith the main<br />

body of data but nonetheless included in the assessment will not typically influence the<br />

outcome of the statistical assessment. Examination of the available meteorological data<br />

suggests that there were no periods of significant rainfall during the survey period.<br />

8.1 to 8.4). A line of best fit has been applied to each dataset (representative of the derived<br />

background noise levels across the range of wind speeds) in relation to which operational<br />

noise limits have been established, as described in ETSU-R-97.<br />

8.3.49 The baseline noise measurement locations used by proxy as representative of other<br />

identified NSRs are detailed in Table 8.1 above.<br />

8.4 Topic Specific Design Evolution<br />

8.4.1 As described in Chapter 3: Design Evolution, in designing the wind farm layout an initial<br />

buffer of 750 m was placed on all identified residential properties in order to minimise the<br />

likelihood of potential NSRs experiencing significant noise effects from the operational<br />

turbines.<br />

8.4.2 An initial scheme noise emission contour of 35dB L A90,10min was electronically modelled to<br />

provide an indication of the likely noise immission levels that would be received at each<br />

identified NSR (see Table 8.1 and Figure 8.1). This model uses the proprietary noise<br />

modelling software SoundPLAN 7.1, and the calculation methodology used by the software is<br />

compliant with ISO9613-2 as recommended in the Acoustics Bulletin article. The noise<br />

immission modelling <strong>for</strong> the Carron Valley Wind Farm has used a candidate wind turbine,<br />

which is the Vestas V-90 of hub height 85 m. It is common practice to adopt this approach to<br />

establish the likely noise effects associated with wind farm proposals and this is discussed in<br />

further detail later in the Chapter.<br />

8.4.3 Cumulative electronic modelling was also undertaken to predict the total noise immission<br />

levels at identified NSRs from the operational Muirpark, Craigengelt, Earlsburn and Earlsburn<br />

North wind farms as well as contributions from the Carron Valley proposals. These<br />

calculations have been based upon the candidate turbine models and methodology adopted<br />

<strong>for</strong> each of the <strong>for</strong>egoing <strong>ES</strong> chapters.<br />

8.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

8.5.1 The proposed development comprises 15 wind turbines with a maximum height to hub of 85<br />

m, a control building and substation, an anemometry mast, a temporary construction<br />

compound and amended vehicular access on to site. A description of the proposed<br />

development is presented in Chapter 4: Description of the Proposed Development.<br />

8.5.2 The following sections assess the likelihood of significant effects associated with noise during<br />

the construction and operational phases of the development.<br />

Construction Effects<br />

Construction Traffic<br />

8.5.3 Abnormal loads transporting turbine components (wind turbine blades, nacelles and tower<br />

components) will follow a predefined route to the site (see Chapter 7: Traffic and Transport<br />

<strong>for</strong> a description of the abnormal load route). Turbine components will be transported to the<br />

site by a specialist heavy haulage contractor.<br />

8.5.4 As identified in Chapter 7: Traffic and Transport, there would be 90 abnormal loads<br />

transporting turbine components to the proposed wind farm over the entire turbine delivery<br />

program. Although it is inevitable that these vehicle pass-by events will be noticeable in<br />

comparison to the composition of existing typical traffic flows, they will be rare and necessary<br />

events which will be scheduled along specific routes. On this basis, it is considered that these<br />

events will not result in any significant adverse noise effects.<br />

Construction on Site<br />

8.5.5 The construction works will follow a 20 month programme. During this period, noise from<br />

construction is likely to arise during: construction of access tracks and crane pads,<br />

construction of lay down area, construction compound and turbine foundations; erection of<br />

turbines; site cabling and substation installation.<br />

8.5.6 Construction activities will not involve piling or blasting, which are the activities generally<br />

considered to have the greatest potential <strong>for</strong> significant construction noise effects.<br />

8.5.7 Due to the attenuation that will be achieved from the propagation of sound over the large<br />

distances between source and receptor it is considered unlikely that construction activities<br />

will give rise to any significant adverse noise effects and no further assessment of noise from<br />

these sources has been undertaken.<br />

8.5.8 It is recognised that noise from construction may occasionally be audible at the closest noise<br />

sensitive receptors, however due to the distance between source and receptor and the lack<br />

of piling or blasting carried out on site, it is there<strong>for</strong>e considered that noise from construction<br />

activities will be slight at most.<br />

8.5.9 It is likely that the determining authority will stipulate core hours <strong>for</strong> construction outside of<br />

which noisy works must not occur. This will serve to minimise any residual noise break-out<br />

from construction activities.<br />

8.5.10 A strategy <strong>for</strong> minimising noise effects in so far as is reasonably practicable is discussed later<br />

in this Chapter.<br />

Vibration Effects During Construction<br />

8.5.11 Construction activities will not involve piling or blasting and, as a result, it is considered highly<br />

unlikely that construction activities will give rise to any significant adverse vibration effects; no<br />

further assessment of vibration effects has been undertaken.<br />

Operational Effects<br />

8.5.12 Noise associated with operation of the substation and routine maintenance visits will be<br />

minimal, there<strong>for</strong>e no further assessment of these aspects is considered necessary. Noise<br />

associated with the operation of the proposed wind turbines is there<strong>for</strong>e the sole focus <strong>for</strong> this<br />

section of the Chapter.<br />

8.5.13 It is common practice to use candidate turbines when assessing the noise effects of a wind<br />

farm because the final turbine choice is often only made when the developer enters into<br />

commercial contract negotiations with a range of turbine manufacturers. The final turbine<br />

choice would have similar noise emissions not exceeding those of the candidate turbine.<br />

Noise immissions from the operational scheme should be controlled by a suitably worded<br />

planning condition, rather than by specifying a single turbine type.<br />

8.5.14 For the purposes of this assessment, a candidate wind turbine, the Vestas V90 3MW has<br />

been used to determine the likely operational noise effects of the proposals.<br />

8.5.15 Manufacturer’s measured noise emission data (A – weighted sound power levels) have been<br />

used in the prediction process, and are summarised in Table 8.3.<br />

8.5.16 A SoundPLAN 7.1 proprietary environmental noise modelling software was used to predict<br />

noise levels resulting from the operation of the proposed wind farm, referencing ISO 9613-2<br />

(see Appendix 8.3). The use of this technique is considered most appropriate <strong>for</strong> predicting<br />

the noise from the proposed wind turbines and is recommended in the Acoustics Bulletin<br />

supplementary guidance. Full details of the modelling procedure are given in Appendix 8.3.<br />

8.5.17 Conservative assumptions have been made in the modelling process and, as such, it is more<br />

likely that the model will over-predict than under-predict noise levels. The ISO 9613-2<br />

method predicts noise levels likely to occur under conditions favourable <strong>for</strong> noise<br />

propagation, i.e. downwind or under a moderate ground-based temperature inversion (which<br />

usually occur in the evening or at night). Upwind conditions may reduce the predicted turbine<br />

noise levels by up to 10 dB. No correction <strong>for</strong> prevailing wind conditions has been applied<br />

throughout the operational noise predictions, including the cumulative assessment presented<br />

in Section 8.8 below.<br />

8.5.18 As the Vestas data are based upon manufacturer-commissioned measurements conducted in<br />

accordance with IEC 61400-11 and as such are not warranted or guaranteed, a ground<br />

absorption factor of G=0 (i.e. hard ground) has been adopted <strong>for</strong> the purpose of the modelling<br />

calculations. Assuming hard ground cover intervening between source and receiver gives rise<br />

to sound immission levels approximately 2 dB higher than if the turbine emission data were to<br />

be warranted or guaranteed, in which case a ground absorption factor of G=0.5 (semi-porous<br />

ground) would have been appropriate. This strategy has been adopted in accordance with<br />

the guidance set out in the Acoustics Bulletin article.<br />

8.5.20 An indicative noise contour plot has been created (see Figure 8.1) at a wind speed of 8 ms -1<br />

which is the wind speed at which the Vestas V90 has the highest measured sound power<br />

level (see Table 8.3 above).<br />

8.5.21 Table 8.5 details the derived ETSU-R-97 noise limits <strong>for</strong> quiet day and night time at each of<br />

the NSRs together with the predicted turbine noise levels presented in Table 8.4 above. It<br />

can clearly be seen that the predicted levels of operational turbine noise from the Carron<br />

Valley Wind Farm comply with the ETSU-R-97 derived operational noise criteria <strong>for</strong> each<br />

NSR during both daytime and night-time periods and across all wind speeds.<br />

Carron Valley Wind Farm<br />

8.5.23 For each of the two representative baseline monitoring locations (Craigannet and Todholes),<br />

scatter charts of measured L A90,10min against concurrent wind speed (standardised to 10 m as<br />

previously described) are presented below <strong>for</strong> quiet day and night time periods. Prevailing<br />

background noise levels across the range of windspeeds are presented in black as a best-fit<br />

curve through each data set. The noise limits varying with windspeed which have been<br />

derived specific to each location and time period in accordance with ETSU-R-97 are<br />

presented in red. The predicted operational noise levels across the range of wind speeds 4 –<br />

12m/s from the Carron Valley Wind Farm at each location is presented in blue..<br />

8.5.24 These scatter charts (8.1 to 8.4) present a graphical representation of the in<strong>for</strong>mation<br />

contained within Table 8.5 above <strong>for</strong> Craigannet and Todholes but clearly show the<br />

relationship between the baseline noise monitoring and the prevailing background levels<br />

derived from the surveys and the ETSU-R-97 derived limits.<br />

Model Uncertainty and Validation<br />

8.5.25 The operational noise predictions cannot be validated until the development is constructed<br />

and operating. The modelling is however sufficiently conservative in its assumptions such<br />

that a realistic worst case has been assessed. The model predictions are based on a widely<br />

validated prediction algorithm, manufacturer’s published data and the proposed wind farm<br />

layout.<br />

8.5.26 The range of measured wind speeds is between 0 - 17 ms-1. There<strong>for</strong>e it is considered that<br />

datasets of sufficient quality and extent have been recorded to enable a reliable ETSU-R-97<br />

assessment to be undertaken.<br />

Low Frequency Noise, Infrasound and Amplitude (Aerodynamic) Modulation<br />

8.5.27 Low frequency noise, infrasound and amplitude modulation are sometimes cited as adverse<br />

effects of operational wind farms. Appendix 8.2 explains the potential sources of these<br />

effects and considers their significance. In summary, under normal circumstances, the levels<br />

of low frequency noise and vibration generated by modern wind turbines are generally<br />

considered to be well below both the limits of perception, and recommended exposure limits<br />

at the nearest properties.<br />

Decommissioning Effects<br />

8.5.28 In the same way as <strong>for</strong> the construction period, it is anticipated that the activities associated<br />

with the future decommissioning of the wind farm would be confined to days of the week and<br />

hours of working agreed with Stirling Council through the use of planning conditions. It is<br />

unlikely that this activity would lead to any greater disruption, since it is expected that<br />

decommissioning of the wind farm will be generally similar to, or quieter than, the<br />

construction phase. This is because the activities involved would be broadly similar and the<br />

plant used would either be similar or quieter.<br />

8.5.29 Decommissioning noise levels are there<strong>for</strong>e considered to be at the most of slight<br />

significance.<br />

8.6 Mitigation and Enhancement Measures<br />

Construction Phase<br />

8.6.1 A Noise and Vibration Management Plan will be incorporated into the HSEMS (see Appendix<br />

4.4) that will identify Best Practicable Means (as defined in the Control of Pollution Act<br />

(CoPA) (1974)), in the <strong>for</strong>m of construction best practice measures, to appropriately and<br />

effectively manage noise and vibration from construction activities. Typical mitigation<br />

measures may include:<br />

• Agreed core hours of noisy working;<br />

• Commitments to using well maintained, low noise emission plant;<br />

• Switching off plant when not in use;<br />

• Considerate management and working to minimise noise effects, e.g. low haul road<br />

speed; and<br />

• Contact details <strong>for</strong> site personnel in case of noise issues.<br />

Operational Phase<br />

8.6.2 No mitigation measures are required.<br />

Decommissioning Phase<br />

8.6.3 A noise assessment would be required prior to the commencement of decommissioning<br />

works and appropriate noise control measures at the time identified and agreed with the<br />

relevant authority.<br />

8.7 Assessment of Residual Effects<br />

8.7.1 Potential noise and vibration effects during construction, operation and decommissioning of<br />

the proposed wind farm have been assessed.<br />

8.7.2 During construction and decommissioning, effects at all nearby receptors are predicted to be<br />

at worst of slight significance. It is considered that adopting the principles of Best Practicable<br />

Means will provide sufficient mitigation to render any residual effects negligible and, as such,<br />

not significant under the terms of the EIA Regulations.<br />

8.7.3 Noise from operation of the proposed wind farm would comply with the requirements of<br />

<strong>ES</strong>TU-R-97 at all residential locations and, as such, operational wind farm noise is<br />

considered not significant under the terms of the EIA Regulations.<br />

8.8 Cumulative Effects<br />

8.8.1 There are 5 relevant wind farm developments in the vicinity of the proposed Carron Valley<br />

Wind Farm at varying stages within the planning process. These are described in Table 8.7<br />

below. It is considered that any wind turbines at a greater separation distances from the site<br />

would not contribute significantly to the cumulative assessment and have there<strong>for</strong>e not been<br />

included. The in<strong>for</strong>mation relevant to each wind farm has been extracted from the relevant<br />

ensuring an absolute worst case assessment. The following Table 8.9 presents the results of<br />

the cumulative operational wind turbine noise assessment <strong>for</strong> all relevant schemes.<br />

8.8.5 Results of the cumulative assessment show that although operational noise levels are<br />

predicted generally to be higher at all NSRs than the Carron Valley scheme levels alone,<br />

predicted cumulative levels remain within the daytime and night-time ETSU-R-97 noise limits<br />

<strong>for</strong> all receptors at all windspeeds.<br />

8.8.6 It is noted that quiet daytime levels at Cairnoch Lodge and Easter Clingate are predicted to<br />

be on the derived limit at wind speeds of 6 and 7 m/s however it should be remembered that<br />

calculations are representative of NSRs being downwind of all wind turbine sources<br />

simultaneously, which results in an overestimate of received operational noise.<br />

8.8.7 Cumulative noise levels at all NSRs at all wind speeds are there<strong>for</strong>e considered not to be<br />

significant under the terms of the EIA regulations. No consideration of mitigation is required.<br />

10 Cultural Heritage and Archaeology<br />

10.1 Introduction and Overview<br />

10.1.1 This chapter considers the direct and indirect effect of the proposed Carron Valley Wind Farm<br />

on the cultural heritage of the area, including buried archaeological sites, historic buildings<br />

and historic landscapes. It aims to identify all effects on these 'historic assets' - in terms of<br />

the potential <strong>for</strong> direct physical disturbance and indirect visual effects on setting - and to<br />

assess the overall effect and significance of these predicted effects.<br />

10.1.2 The following stages of the proposed development are likely to affect the historic<br />

environment:<br />

• Construction - this will be the phase where direct physical effects to any buried<br />

archaeology are most likely to occur;<br />

• Operation - this is the phase during which visual effects on the settings of surrounding<br />

historic assets will occur;<br />

• Decommissioning - this is the phase during which the components of the wind farm will<br />

be removed.<br />

10.1.3 The construction of the tracks, turbine foundations, crane pads, control building, construction<br />

compounds, borrow pits and cabling - as they will all involve significant groundworks - have<br />

the potential to disturb buried archaeological remains.<br />

10.1.4 A thorough desk-based assessment (see Appendix 10.1) of the area of the proposed wind<br />

farm (see Figure 10.1), followed by a site walkover on 11 November 2011, <strong>for</strong>ms the basis <strong>for</strong><br />

the assessment of the potential <strong>for</strong> known and unknown remains on the site to be physically<br />

disturbed by the proposed wind farm. This in<strong>for</strong>mation was fed into the design process and<br />

the final proposals have, to the greatest extent possible, avoided direct effects on known<br />

archaeological sites.<br />

10.1.5 The proposed development comprises 15 wind turbines with a maximum hub height of 85 m<br />

and maximum heights to blade tip of 126 m, which will be seen <strong>for</strong> a considerable distance in<br />

the surrounding landscape and there<strong>for</strong>e have the potential to affect the settings of a number<br />

of historic assets.<br />

10.1.6 The assessment of visual effects on setting is addressed using the computer-generated Zone<br />

of Theoretical Visibility (ZTV) to establish which sites are likely to have views of the turbines<br />

or where the turbines may affect appreciation of important views from or towards historic<br />

assets. Those historic assets that will be affected are then considered in two groups: those<br />

within 3.5 km of the nearest turbine, where effects are likely to be greatest, and between<br />

3.5 km and 10 km away. Beyond 10 km it is considered that any effects will be minimal,<br />

particularly within Carron Valley where the containing effect of the surrounding landscape<br />

means that there will be no notable views of the proposed wind farm beyond approximately<br />

8 km, except in a narrow corridor to the west.<br />

10.1.7 Mitigating the potential effects of the proposed development has largely been addressed<br />

through the design evolution process. In particular, by carrying out a full and detailed<br />

assessment of the location of historic assets within the land holding it has been possible to<br />

avoid direct physical effects on known archaeological sites.<br />

10.1.8 The chapter is structured as follows:<br />

• Methodology;<br />

• Baseline In<strong>for</strong>mation;<br />

• Topic Specific Design Evolution;<br />

• Potential Significant Effects of the Scheme Prior to Mitigation;<br />

• Mitigation and Enhancement Measures;<br />

• Assessment of Residual Effects; and<br />

• Cumulative Effects.<br />

10.2 Methodology<br />

10.2.1 This section includes the following topics:<br />

• Consultation;<br />

• Baseline survey methodology (desk-based assessments, walk-over);<br />

• Assessment methodology (criteria used to assess levels of direct and indirect, visual<br />

effects).<br />

Consultation<br />

10.2.2 Through the <strong>for</strong>mal Scoping Opinion, initial responses were obtained from Historic Scotland<br />

and Stirling Council. A meeting with the Stirling Council Archaeology officer was held on 31<br />

January 2012, at which time potential direct and indirect effects on the historic environment<br />

and appropriate mitigation strategies were discussed.<br />

10.2.3 Consultation concerning appropriate methodology <strong>for</strong> assessing ‘indirect’ visual effects has<br />

taken the <strong>for</strong>m of an initial meeting with representatives of Historic Scotland (HS) on 15<br />

November 2011 followed by submission of a number of requested visualisations. Historic<br />

Scotland responded to this in a letter dated 7 February 2012 (see Appendix 10.5) setting out<br />

a number of concerns about the proximity of turbines to Sir John de Graham’s Castle<br />

Schedule Monument. As a result of these concerns, the proposed wind farm in the vicinity of<br />

the Castle was redesigned and the number of turbines ultimately reduced from 16 to 15 (see<br />

Section 10.4: Topic Specific Design Evolution and Chapter 3: Design Evolution).<br />

Baseline Survey Methodology<br />

Desk-Based Assessment<br />

10.2.4 The first stage in the baseline assessment of the proposals site involved the preparation of a<br />

desk-based assessment (DBA) in accordance with IFA guidelines. The direct effects and<br />

proposed mitigation measures outlined in the DBA document have been included in this<br />

chapter, as has the gazetteer of historic assets within and close to the proposed site (see<br />

Walkover Survey<br />

10.2.5 A walkover survey of the proposed site was carried out on 11 November 2011. All features<br />

and sites of possible archaeological significance identified on aerial photographs as well as<br />

scheduled sites and those listed in the SMR were checked on the ground. Each site of<br />

archaeological significance was located using a hand-held GPS, photographed, described<br />

and, if appropriate, sketched.<br />

Assessment Methodology<br />

10.2.6 This section sets out the methodology used <strong>for</strong> assessing physical effects on any buried<br />

archaeology on the proposed wind farm site and on the settings of historic assets in the wider<br />

landscape, in line with the overall EIA methodology presented in Chapter 2: The<br />

Environmental Impact Assessment and Scoping Process.<br />

Historic Asset Importance<br />

10.2.7 In order to reach an understanding of the significance of any effect that a proposed<br />

development may have on a historic asset, it is necessary to understand the importance of<br />

that asset, <strong>for</strong> example its importance at a national level, regional or local level.<br />

10.2.8 This chapter provides assessments of significance both of cultural heritage resources (in this<br />

case mostly archaeological sites), and of the effects that the proposed development is likely<br />

to have on them. Professional judgement and a degree of flexibility are relevant to the<br />

assessment process. There are occasions when limited in<strong>for</strong>mation about buried<br />

archaeological resources requires an assessment of risk to be extrapolated from broader<br />

knowledge of the region and periods involved.<br />

10.2.9 A detailed assessment of hierarchies of importance of buried archaeological remains, historic<br />

buildings and historic landscapes can be found in Appendix 10.2, which <strong>for</strong>ms the basis <strong>for</strong><br />

the following summary of levels of historic asset importance:<br />

• High - National: the highest status of site e.g. Scheduled Monuments, Listed Buildings<br />

Category A and B; registered Historic Battlefields; registered Historic Parks and<br />

Gardens;<br />

• Medium - Regional: the bulk of sites with reasonable evidence of occupation, ritual,<br />

industry etc., Category C Listed Buildings, well preserved historic landscapes;<br />

• Low - Local: sites with some evidence of human activity, but in a fragmentary or poor<br />

state, buildings of local importance, dispersed elements of historic landscapes; and<br />

• Negligible - Unimportant: destroyed, non-antiquities, random stray finds, buildings of<br />

no architectural merit.<br />

Magnitude of Change<br />

10.2.10 The magnitude of effect is assessed without regard to the importance of the historic asset. In<br />

terms of the judgement of the magnitude of effect, this is based on the well-established<br />

principle that preservation of the asset is preferred, and that total physical loss of the asset is<br />

the least preferred.<br />

10.2.11 The following summary scale of magnitude of effect is based on a more detailed set of criteria<br />

<strong>for</strong> buried archaeological remains, historic buildings and historic landscapes set out in<br />

Appendix 10.3:<br />

Carron Valley Wind Farm<br />

• Large: Changes to most or all key archaeological elements, such that the asset is<br />

totally altered and much of its significance is lost. Substantial change within the setting<br />

leading to considerable loss of significance of the asset.<br />

• Medium: Changes to many key archaeological elements, such that the asset is clearly<br />

modified and there is some loss of significance. Change within the setting leading to<br />

some loss of significance of the asset.<br />

• Small: Changes to key archaeological elements, such that the asset is slightly altered<br />

and there is a slight loss of significance. Slight change within the setting leading to a<br />

slight loss of significance of the asset.<br />

• Negligible: Very minor changes to key archaeological elements or within the setting<br />

that hardly affect the significance of the asset.<br />

• None: No substantive change to key archaeological elements or within the setting.<br />

10.2.12 For the purposes of this assessment, effects of medium adverse or greater are considered to<br />

be significant in line with the EIA Regulations.<br />

10.2.13 Additional methodology regarding the assessment of effects on settings is provided below<br />

under the heading 'Settings'.<br />

Significance of Effects<br />

10.2.14 The significance of effects is a combination of the importance of the historic asset and the<br />

magnitude of effect on that asset. Effects can be adverse or beneficial. Beneficial effects are<br />

those that mitigate existing effects and help to restore or enhance the significance of historic<br />

assets, there<strong>for</strong>e allowing <strong>for</strong> greater understanding and appreciation. In line with DMRB<br />

Guidance Note 208/07 the matrix in Table 10.1 has been applied to effects on buried<br />

archaeological remains, historic buildings and historic landscapes.<br />

Settings<br />

10.2.16 The methodology <strong>for</strong> assessing effects on settings provided here is based on the latest policy<br />

and guidance including Historic Scotland guidance Managing Change in the Historic<br />

Environment: Setting (Historic Scotland, 2010) which states that “Setting should be thought of<br />

as the way in which the surroundings of a historic asset or place contribute to how it is<br />

experienced, understood and appreciated.” (paragraph 2.1)<br />

10.2.17 The paper goes on to point out in this context that monuments, buildings and gardens were<br />

constructed with reference to their surroundings, relationships that need not be limited to the<br />

immediate property boundary.<br />

10.2.18 The Historic Scotland guidance provides a template <strong>for</strong> assessing the effects of development<br />

on the settings of historic assets comprising three stages:<br />

• Stage 1: identify historic assets;<br />

• Stage 2: define and analyse setting; and<br />

• Stage 3: assess the effect of new development.<br />

10.2.19 In light of this, the methodology <strong>for</strong> the assessment of settings used here has been<br />

developed by RPS to make the process of assessing effects on settings as consistent,<br />

transparent and comprehensible as possible.<br />

Identifying Historic Assets<br />

10.2.20 Up to date in<strong>for</strong>mation on designated assets in the area of the wind farm was acquired from<br />

Historic Scotland, while in<strong>for</strong>mation on non-designated assets has been acquired from<br />

Stirling Council’s Historic Environment Record, through a site walkover and from a variety of<br />

published sources including historic maps.<br />

10.2.21 Experience demonstrates that significant visual effects on historic assets rarely occur beyond<br />

a distance of around 10 km. For this reason the assessments contained within this chapter<br />

are limited to this distance, although there has been consideration of nationally important<br />

receptors beyond this on a case-by-case basis where considered appropriate. Furthermore, it<br />

is generally the case that the highest level of visual effects on historic assets tend to occur<br />

within 3.5 km. For this reason the assessments below are divided into historic assets up to<br />

3.5 km from the nearest of the proposed turbines and those between 3.5 km and 10 km from<br />

the nearest turbine.<br />

10.2.22 A key tool in undertaking this type of assessment is the ZTV, which models those areas in the<br />

surrounding landscape from where there will be direct lines of sight, however slight, of the<br />

proposed development (see Figure 10.2). It is important to recognise that the ZTV represents<br />

a worst-case scenario as it does not take account of vegetation, <strong>for</strong>estry or built <strong>for</strong>m and is<br />

‘triggered’ by visibility of a single blade tip.<br />

10.2.23 The sites most likely to be significantly affected by the proposed wind farm are there<strong>for</strong>e<br />

designated sites of national importance that lie within 3.5 km of the nearest turbine.<br />

Nevertheless, significant effects are possible at greater distances and, in some exceptional<br />

cases (<strong>for</strong> example with iconic landscape monuments such as Stirling Castle which falls<br />

outside the ZTV <strong>for</strong> this site), beyond 10 km.<br />

Definition and Analysis<br />

10.2.24 The guidance sets out a non-definitive list of a number of issues that should be addressed<br />

when considering setting as follows:<br />

• “How do the surroundings contribute to our ability to appreciate and understand a<br />

historic asset or place?<br />

• When the historic asset or place was developed or in use, was it located to be seen<br />

from a distance, perhaps from other sites or buildings?<br />

• Was it intended to have wide views over the landscape?<br />

• How does a historic asset or place contribute to its surroundings: <strong>for</strong> instance, is it a<br />

prominent or dominant feature in the landscape?”<br />

10.2.25 An assessment of the sensitivity of the setting of a historic asset requires consideration of its<br />

broader landscape and historic context. Thus, while the existence of direct lines of sight<br />

between the designated receptor and the proposed turbines is a key factor in judging the<br />

visual effect of the development, it is possible <strong>for</strong> its setting to be affected even when such a<br />

relationship does not exist. For example, views of listed buildings from a popular location,<br />

such as a park or other public amenity, may be impacted by the presence of wind turbines,<br />

even if they are not visible from the building itself.<br />

10.2.26 Conversely, the use of these combined criteria means that, although the proposal may have<br />

a clear visual effect, the overall effect on the setting of the resource may be lessened if the<br />

resource’s setting has a low sensitivity to change.<br />

Assessing the Effect of New Development<br />

10.2.27 Assessing effects on the settings of cultural heritage resources is largely a case of in<strong>for</strong>med<br />

professional judgement. The procedure explained below aims to combine an objective<br />

assessment of the magnitude of change of the setting of an identified cultural heritage<br />

resource with a judgment of the sensitivity of its setting to change. This covers a variety of<br />

considerations including the following set out in the Historic Scotland guidance:<br />

• the visual effect of the proposed change relative to the current place of the historic<br />

asset or place in the landscape;<br />

• the presence, extent, character and scale of the existing built environment within the<br />

surroundings of the historic asset or place and how the proposed development<br />

compares to this;<br />

• the magnitude and cumulative effects of the proposed change – sometimes relatively<br />

small changes, or a series of small changes, can have a major effect on our ability to<br />

appreciate and understand a historic asset or place;<br />

• the ability of the landscape, which comprises the setting of a historic asset or place, to<br />

absorb new development without eroding its key characteristics;<br />

• the effect of the proposed change on qualities of the existing setting such as sense of<br />

remoteness;<br />

• the historical past, sense of place, cultural identity, spiritual responses.<br />

10.2.28 The following summary scale of effect magnitude is used in assessing the magnitude of<br />

visual effects on the setting of cultural heritage resources. This accords with the requirements<br />

of the Guidelines <strong>for</strong> Landscape and Visual Impact Assessment (GLVIA) (The Landscape<br />

Institute with the Institute of Environmental Management and Assessment, Second Edition,<br />

2002) and is presented in line with the detailed assessment of visual effects in Chapter 9:<br />

Landscape and Visual Impact Assessment:<br />

• Very Large - the proposals would result in a major change within the setting of a<br />

historic asset.<br />

• Large - the proposals would result in a substantial change within the setting of a<br />

historic asset.<br />

• Medium - the proposals would result in a moderate change within the setting of a<br />

historic asset.<br />

• Small - the proposals would result in a slight change within the setting of a historic<br />

asset.<br />

• None - the proposals would result in no appreciable change within the setting of a<br />

historic asset.<br />

10.2.29 Appraisal of the sensitivity of the setting of a cultural heritage resource to change<br />

incorporates a number of factors as outlined above. The levels are set as:<br />

• Reduced - the significance of an asset is not likely to be affected by development<br />

within its surroundings - there are already several detracting elements within the<br />

setting and few contributory elements.<br />

• Restricted – the significance of an asset may be slightly diminished by development<br />

within its surroundings - there are some detracting elements within the setting and<br />

some contributory elements.<br />

• Notable – the significance of an asset may be substantially diminished by<br />

development within its surroundings - there are several contributory elements within<br />

the setting and few detracting elements.<br />

• Elevated - the significance of an asset may be wholly diminished by development<br />

within its surroundings - there are a number of contributory elements within the setting<br />

and almost no detracting elements.<br />

10.2.30 Table 10.2 identifies the methodology <strong>for</strong> assessing the degree of effects on the settings of<br />

cultural heritage resources, which is a function of the magnitude of visual effect on the setting<br />

of the resource (as indicated in Table 10.1 above) with the sensitivity of the resource to<br />

change. Table 10.2 is not designed as an absolute predictive tool, but to make the<br />

professional judgements contained within this report as transparent as possible. Where the<br />

table gives two possible outcomes, e.g. Moderate / Slight, the allocation of one of these<br />

outcomes is made by the assessor on the basis of the individual circumstances of the<br />

resource, the visual effect and the amenity value, using professional judgement and<br />

expertise. For example, a medium magnitude of change on a setting of notable sensitivity<br />

would result in a medium or slight degree of effect on the setting, and the assessor would<br />

decide which one of these is the most appropriate.<br />

10.2.31 The effects described in Table 10.2 can be adverse or beneficial.<br />

10.2.32 The overall significance of effect on settings is a function of the degree of effect on setting<br />

and the importance of the asset as set out in Table 10.1.<br />

National Planning Policy and Guidance<br />

10.3.2 The legislative framework provides protection <strong>for</strong> the historic environment while planning<br />

policy guidance provides advice concerning how the historic environment should be<br />

addressed within the planning process.<br />

10.3.3 The UK is a signatory of the Valletta Convention (Council of Europe, 1997) which requires<br />

legal protection of the archaeological heritage.<br />

10.3.4 Statutory protection <strong>for</strong> archaeology is principally enshrined in the Ancient Monuments and<br />

Archaeological Areas Act (1979) as amended. Nationally important archaeological sites are<br />

listed in a Schedule of Monuments and are accorded statutory protection.<br />

10.3.5 For other components of the historic environment, the Planning (Listed Buildings and<br />

Conservation Areas) (Scotland) Act 1997 provides statutory protection to listed buildings and<br />

their settings and present measures to designate and preserve the character and appearance<br />

of Conservation Areas.<br />

10.3.6 The Town and Country Planning (Development Management Procedure) (Scotland)<br />

Regulations 2008 requires planning authorities to consult Scottish Ministers on “development<br />

which may affect…a garden or designed landscape”. Historic Scotland’s views are a material<br />

consideration in planning determinations affecting such sites. An Inventory of Gardens and<br />

Designed Landscapes in Scotland was originally published by Historic Scotland in 1987-88<br />

and has been supplemented since. The full up-to-date list is available on the Pastmap<br />

website.<br />

10.3.7 Scottish Planning Policy (February 2010) includes a section providing advice on safeguarding<br />

the historic environment within the planning process. It states that “when significant elements<br />

of the historic environment are likely to be affected by development proposals, developers<br />

should take the preservation of this significance into account in their proposals”.<br />

10.3.8 Scottish Historic Environment Policy (SHEP) was published in July 2009 and provides<br />

detailed guidance to planning authorities when considering planning applications that affect<br />

the historic environment. It states that “the challenge <strong>for</strong> sustainable management of the<br />

historic environment…is to identify its key characteristics and to establish the boundaries<br />

within which change can continue so that it enhances rather than diminishes historic<br />

character”.<br />

10.3.9 These policy documents are supported by PAN 2/2011, ‘Planning and Archaeology’,<br />

published in July 2011. This sets out the responsibilities of planning authorities to protect<br />

archaeological remains, balancing “the benefits of the development against the importance of<br />

archaeological features”. It states the need <strong>for</strong> Historic Scotland to be consulted when<br />

Scheduled Monuments are directly affected. In paragraph 14 it further states that the<br />

objective of planners “should be to assure the protection and enhancement of monuments by<br />

preservation in situ in an appropriate setting (perhaps with a degree of interpretation)”.<br />

10.3.10 When considering the effects of wind farms on the settings of historic assets, the key<br />

guidance is Historic Scotland’s guidance on setting published in October 2010, previously<br />

referenced. This provides general guidance to how to define setting and assess the effects of<br />

development proposals on the settings of historic assets.<br />

Local Planning Policy<br />

Stirling Council<br />

10.3.11 The policies set out below were published in Stirling’s Local Plan in 1999 and remain<br />

applicable pending the completion of the Local Development Plan currently in preparation.<br />

10.3.12 POL.E47 There will be a presumption against any development proposal which would have<br />

an adverse effect on:<br />

(a) a scheduled ancient monument or its setting; or<br />

(b) unscheduled remains and their settings which have been identified as particularly<br />

worthy of preservation.<br />

10.3.13 POL.E48 When considering development proposals which would adversely affect features of<br />

archaeological importance, the Council must be satisfied that the benefits of the proposed<br />

development will outweigh the disturbance of the archaeological interest. Approval of any<br />

such proposal, where preservation of the archaeological interest is not possible, will be<br />

conditional upon satisfactory provision being made by the developer <strong>for</strong> the appropriate level<br />

of archaeological investigation, including publication of the results.<br />

Carron Valley Wind Farm<br />

10.3.14 POL.E49 Where there is an indication that archaeological remains may exist within a<br />

development proposal but their extent and significance is unclear, the Council will require the<br />

prospective developer to arrange <strong>for</strong> an evaluation prior to the determination of the<br />

application in order to establish the importance of the site, its sensitivity to development and<br />

the most appropriate means <strong>for</strong> preserving or recording surviving archaeological features.<br />

10.3.15 POL.E50 Where the presence of archaeological interest becomes apparent once a<br />

development has commenced, adequate opportunity must be af<strong>for</strong>ded by the developer <strong>for</strong><br />

an archaeological investigation. It is desirable that, where possible, important archaeological<br />

remains are preserved in situ.<br />

10.3.16 In addition to these policies, in March 2011 Stirling Council adopted Supplementary Planning<br />

Guidance on Locational Policy & Guidance <strong>for</strong> Renewable Energy Developments. This<br />

includes notes on ‘local guidance and criteria’ which, in relation to the historic environment,<br />

specify that: “Developers will be expected to take into account Scheduled Ancient<br />

Monuments, Listed Buildings and their settings (especially Category A buildings and<br />

structures), Conservation Areas and Inventory Gardens & Designed Landscapes.”<br />

10.3.17 In the Stirling area, two battle sites – Bannockburn and Sheriffmuir – are of importance and<br />

the Council will consider their implications <strong>for</strong> the siting of any large wind turbines that may<br />

affect their setting. (Historic Scotland has issued draft definitions/maps of these sites –<br />

(Historic Scotland, 2011).<br />

10.3.18 Developers will be expected to consider sites listed in the Sites and Monuments Record <strong>for</strong><br />

the area when considering the location of wind farms and the detailed siting of turbines.<br />

Baseline Conditions<br />

Topography and Geology<br />

10.3.19 The solid geology is fairly uni<strong>for</strong>m across the site, made up of extrusive igneous rocks<br />

(basaltic lavas) from the Clyde Plateau <strong>Vol</strong>canic Formation. Superficial deposits across the<br />

site are predominantly Devensian till deposits. The hills around the Carron Valley comprising<br />

volcanic Clyde Plateau basalts overlain in the valleys by Devensian till. The site lies within the<br />

Carron Valley. To the north lie the Fintry, Gargunnock and Touch Hills which combine as an<br />

undulating plateau of uplands and to the south lies the ridge of Kilsyth Hills and Campsie<br />

Fells. These upland areas provide the immediate context of the proposal site.<br />

10.3.20 The proposed site lies on the western and southern sides of Cairnoch Hill that is situated in<br />

the centre of this area of upland. To the south lies the Carron Valley Reservoir, completed in<br />

1939. The dam lies approximately 2 km to the east of the site beside Craigannet Farm. The<br />

reservoir is fed by runoff within the upper River Carron catchment. Additionally water can be<br />

diverted from the Endrick Water into the reservoir if required. Backside Burn, that runs down<br />

the valley immediately to the west of Cairnoch Hill, is a tributary of Endrick Water.. To the<br />

south of the reservoir the commercial <strong>for</strong>estry covers a wide area of hills, including the<br />

highest peak in the area, Meikle Bin (570 m).<br />

10.3.21 Cairnoch Hill itself reaches a maximum elevation of 413 m. The proposed turbines would be<br />

constructed at elevations of between 250 m and 350 m Above Ordnance Datum (AOD).<br />

10.3.22 Be<strong>for</strong>e the construction of the Carron Valley Reservoir, the road that <strong>for</strong>ms the southern<br />

boundary of the modern <strong>for</strong>est ran slightly further to the south where it passes Sir John De<br />

Graham’s Castle Scheduled Monument as far as the historic farm at Cairnoch. The original<br />

course of the River Carron lay on the south side of the valley, hugging the base of Haugh Hill,<br />

separated from Cairnoch Hill by a wide area of flat bog. By the later nineteenth century, the<br />

valley floor had been extensively improved, <strong>for</strong>ming part of Finniegh Haugh Farm which lay<br />

on the south side of the valley. The parish boundary of St Ninians runs east-west broadly<br />

along the centre of the valley.<br />

Soils<br />

10.3.23 There are essentially two different soil types on the proposed site as indicated on the one<br />

inch to one mile (1:63,360) Soil Survey of Scotland Sheet 39 (Stirling) (British Geological<br />

Survey, 1967). Hill peats, generally 0.5 m to 1 m in depth, with occasional deeper patches,<br />

extend across much of the northern-western side of Cairnoch Hill. There are limited peat<br />

deposits located within the north west boundary of the site. The remainder of the site is<br />

characterised by three different mineral soils series’ <strong>for</strong>med in fine to medium textured glacial<br />

till. The best drained of these – the Darleith soils – correspond fairly closely to the areas<br />

known to have been cultivated in the medieval and post-medieval periods: the area around<br />

Sir John De Graham’s Castle, and other patches on the lower southern slopes of the hill<br />

including either side of the stream west of Cairnoch, Cairnoch itself and the area around the<br />

site of Kirk O’Muir near the proposed site access. The remaining areas are poorly drained<br />

with peaty topsoils.<br />

Archaeology<br />

Early Prehistoric (c.10000-c.700BC)<br />

10.3.24 There are few recorded traces of Neolithic or Mesolithic date in the vicinity of the proposed<br />

site. Remains of this period may survive beneath alluvium and peat deposits.<br />

10.3.25 Recent surveys in the area have identified significant numbers of Bronze or Iron Age hut<br />

circles to the west of Cairnoch Hill, on lower ground to the west of Endrick Water (sites 2-6),<br />

and on the east-west ridge running down towards Easter Cringate to the north of the site.<br />

These tend to be 5-7 m in diameter, defined by banks and occasionally the preserved<br />

remains of walls. A variety of earthwork features may be associated with these remains of<br />

later prehistoric settlement including lazy beds (similar to cord rig). This clearly points towards<br />

the widespread preservation of settlement of this period in the area, perhaps on south-facing<br />

slopes in particular. This is likely to apply to the area of Cairnoch Hill also, although in those<br />

areas that fall within <strong>for</strong>estry any trace of such features are likely to have been largely or<br />

entirely destroyed.<br />

10.3.26 The two scheduled cairns north of Todholes are likely to be Bronze Age burial mounds<br />

(Figure 10.2, SM 2 & SM 3). Examination of historic (pre-<strong>for</strong>estry) aerial photographs shows<br />

no trace of any such barrows within the proposed wind farm site.<br />

10.3.27 The presence of such widespread evidence of Bronze Age settlement in an upland area such<br />

as this is entirely consistent with the picture more widely in central and lowland Scotland.<br />

Iron Age (c. 700BC-AD400)<br />

10.3.28 Across the region of central/southern Scotland there is a marked change in settlement<br />

pattern from around the seventh century BC onwards, with the disappearance of the open<br />

settlements with associated field systems of the Bronze Age to the largely enclosed and<br />

<strong>for</strong>tified settlement that characterises the Iron Age.<br />

farm site, notably on the west side of Fintry Village, with the scheduled sites of Craigton Dun<br />

(SM 15), and the <strong>for</strong>ts at Dunmore (SM 17) and Dunbeg (SM 16) on slopes overlooking<br />

Endrick Water. To the east there is a defended enclosure on the east side of the summit of<br />

Dundaff Hill (SM 18). There is no evidence <strong>for</strong> such settlements on Cairnoch Hill.<br />

Early Historic (c. AD400-c.1200)<br />

10.3.30 No clear evidence of settlement during this period is known from the area at a time when it<br />

fell on the fringes of the Pictish kingdom, that lay on the western side of Scotland to the north<br />

of the Forth, and the kingdom of Strathclyde to the south-west. Cairnoch Hill falls within the<br />

historic parish of St Ninians, but is recorded in some medieval documents as Egglis or<br />

Eccles, a toponym normally associated with the late/sub-Roman Christianisation of lowland<br />

Scotland.<br />

10.3.31 The Parish of St Ninian is exceptionally large, extending from the Forth to the north to the<br />

Carron to the south. It is unclear at which date it came into being as a territory, but the fact<br />

that it holds a name with sub-Roman/early medieval associations suggests that it may go<br />

back this far. If so the proposed wind farm site lies on its southern boundary, a location that<br />

may have been of some strategic importance. By the eleventh century, the area had fallen<br />

under the control of the Scots, expanding from their base in Argyll.<br />

Medieval (c.1200-1700)<br />

10.3.32 By the thirteenth century the influence of the Norman administration to the south was<br />

increasingly strong. This saw the development of feudal society focussed on local<br />

aristocracies based in motte and bailey castles. Sir John De Graham’s Castle, which lies<br />

immediately to the south-west of the proposed wind farm, may have its origins in this period<br />

as the seat of the Barony of Dundaff which is known to have existed as early as 1237. Sir<br />

John de Graham, after whom the site is named, was heir of this title and died at the Battle of<br />

Falkirk in 1298 fighting with William Wallace against the English. The location of the castle at<br />

the south-western corner of St Ninian’s Parish, at the point where Endrick Water and the<br />

River Carron run closest, was in many ways the strategic key to movement through the<br />

uplands to the south-west of Stirling.<br />

10.3.33 Little archaeological fieldwork has previously taken place on the site and overall<br />

understanding of its history there<strong>for</strong>e remains poor. The description provided here is based<br />

on a site visit and examination of pre-<strong>for</strong>estry aerial photographs held by the Royal<br />

Commission of Ancient and Historic Monuments <strong>for</strong> Scotland (RCAHMS). A square moated<br />

plat<strong>for</strong>m, c22 m across inside a moat c11 m wide and c3 m deep, oriented to the south-west,<br />

stands on a spur on the south-west side of Cairnoch Hill that commands a view of the Carron<br />

Valley in both directions (Figure 10.3; feature F). There are traces of stone buildings on the<br />

north-east (upslope) side of the moat (G). Aerial photography taken be<strong>for</strong>e the plantation of<br />

commercial <strong>for</strong>estry indicates the presence of a large square enclosure to the north-east (A),<br />

while there are suggestions of a possible track approaching the site from the south-east (B).<br />

There are earthworks beside the stream immediately to the west of the site that appear to<br />

have once supported a small bridge (C). Running south from this point on the east side of the<br />

stream is a bank, still a clearly discernable earthwork feature, presumably to control the water<br />

flow. On the basis of other motte and bailey castles in Scotland, it may be that the original<br />

building on the site was wooden, replaced in the later thirteenth century in stone.<br />

10.3.34 Kirk O’Muir, the <strong>for</strong>mer chapel that stood at the south-eastern corner of Carron Forest and of<br />

which only the burial ground now survives, is believed to date back to the late medieval<br />

period. Indeed some documents suggest that it may once have controlled its own parish or<br />

sub-parish, perhaps not surprisingly given the size of St Ninians Parish and the distance from<br />

the mother church near Stirling. This being so, both chapel and parish are likely to have been<br />

dominated by the Barons of Dundaff.<br />

10.3.35 The first clear evidence <strong>for</strong> the development of the area in the later medieval period is<br />

provided by early maps. These show a landscape of upland moor – much of it presumably<br />

used <strong>for</strong> grazing sheep and cattle – with scattered farmsteads along the river and stream<br />

valleys, each associated with patches of rig and furrow cultivation. It is likely that some of<br />

these farms date back to the medieval period.<br />

10.3.36 The late sixteenth century Pont map (Pont, 1583-1601) depicts Sir John De Graham’s Castle<br />

as ‘Dundaff Castle’ with a symbol of a tower suggesting that it was a standing building at this<br />

time. This might indicate that the masonry footings to the north of the square motte are the<br />

remains of this late medieval/early post-medieval building, probably a tower house of the sort<br />

that is better preserved at Fintry Castle, c4 km to the west (SM 7). It also marks the presence<br />

of a series of farmsteads along the north side of the Carron Valley to the east of Sir John De<br />

Graham’s Castle within the area of the modern <strong>for</strong>est:<br />

• ‘Santauries’ (later known as Smallburn – the site of which is visible immediately south<br />

of Sir John De Graham’s Castle on the edge of the reservoir; site 49);<br />

• ‘Boigsyde’ (Bogside: also inundated by the reservoir but marked on early Ordnance<br />

Survey maps half way between Sir John De Graham’s Castle and Cairnoch; site 51).<br />

The bog referred to is presumably that in the base of Carron Valley to the south;<br />

• ‘Krimzetts’ (probably to be identified with Cairnoch);<br />

• ‘K. of Moore’ (Kirk O’Muir; site 15), shown as a square tower marked with a cross<br />

beside a separate tower, the significance of which is not immediately obvious. This<br />

does, however, suggest that the church was still in use at this time.<br />

10.3.37 The area to the north of the valley is labelled simply as ‘Dundaff Moore’.<br />

10.3.38 On the mid-seventeenth century revision of Pont’s map (Gordon, 1636-1652) by Robert and<br />

James Gordon, Sir John De Graham’s Castle is labelled as ‘Ruynis of Grayme Castell’<br />

beside the label ‘Dundaff C(astle)’, suggesting that it may have been abandoned in the early<br />

seventeenth century.<br />

Post-Medieval (c.1707-present)<br />

10.3.39 By the mid-eighteenth century, with the first accurate survey available in the <strong>for</strong>m of Roy’s<br />

military map of 1752-1755 (Roy, 1747-1755), the picture becomes clearer. The following<br />

features can be identified to the north of the road (identified here as the ‘Road from Fintray to<br />

Falkirk):<br />

• Sir John De Graham’s Castle is labelled simply as ‘Graham’s Castle’;<br />

• Smallburn (as marked on later maps) to the north, is labelled ‘Bogside’;<br />

• Bogside (as marked on later maps) is not shown;<br />

• A settlement called ‘Sheen Hill’ is shown beside the road to the west of the stream that<br />

runs down the side of Cairnoch Hill to the west of Cairnoch Farm (site 48), while to the<br />

east of the stream is shown Ashen Tall (site 47);<br />

• Cairnoch Farm does not seem to be marked, although a farmstead named Hole Craig<br />

is shown further up the side of the hill;<br />

• ‘Aboon the Kirk’, marked on later maps as Boon ‘o Kirk (site 50; presumably the house<br />

of the priest attached to the local church) is shown <strong>for</strong> the first time;<br />

• East of this is another farmstead named Dyke House the site of which appears to lie in<br />

the <strong>for</strong>estry 100-200 m north of Kirk O’Muir;<br />

• Finally Kirk of Muir is marked in the position of the surviving graveyard. On Edgar’s<br />

map of approximately the same date (Edgar, 1745) the site is labelled as ruins<br />

indicating that it, like the castle, had fallen out of use.<br />

10.3.40 Upslope and around all of these farmsteads large areas of cord rig (i.e. improved ground) are<br />

indicated on Roy’s map. The early OS maps suggest that these areas extended up to<br />

approximately the 275 m contour.<br />

10.3.41 On the first detailed OS maps (OS, 1865) (surveyed in 1858-1863) Smallburn and Bogside<br />

(both subsequently abandoned owing to the construction of the reservoir), Cairnoch and<br />

Boon a’Kirk and are shown in detail. Sheen Hill and Ashen Tall are marked by a group of<br />

improved fields but nothing more. There is no trace of Craig Hole or Dyke House.<br />

10.3.42 The situation changed relatively little be<strong>for</strong>e the construction of the Carron Valley Reservoir in<br />

1939, with a dam erected 2.3 km west of Carron Bridge. This flooded the famously boggy<br />

base of the valley as well as the lower slopes of the hills to either side. As a result the old line<br />

of the Fintry-Falkirk road now lies partly under water. It can clearly be seen running some<br />

85 m south of the present road as it passes Sir John De Graham’s Castle, at which point the<br />

earthwork remains of Smallburn lie at the water’s edge.<br />

Historic Landscape<br />

Scottish Historic Land-Use Assessment<br />

10.3.43 No historic landscape characterisation has been carried out in Stirlingshire. The Scottish<br />

Historic Land-Use Assessment (HLA) is the nearest thing (http://hla.rcahms.gov.uk/). It is a<br />

mapped analysis of past and present land-use in Scotland. The area of the proposed wind<br />

farm falls within the following land-use categories:<br />

• 18 th -19 th century fields and farming;<br />

• 20 th century coniferous plantation;<br />

• 19 th century reservoir;<br />

• 20 th century roads;<br />

• Prehistoric-modern moorland and rough grazing.<br />

Previous Effects<br />

Carron Valley Wind Farm<br />

the proposed development is the effect that the commercial <strong>for</strong>estry plantation has already<br />

had on these aspects of the historic environment.<br />

10.3.45 The intensive use of deep ploughing and/or mechanical plant across the entire area of the<br />

proposed wind farm <strong>for</strong> the planting of trees is highly destructive as far as almost all<br />

categories of buried archaeology are concerned. In particular, it cannot be expected that<br />

relatively ephemeral remains – such as buried ancient land surfaces with associated<br />

prehistoric remains – will survive in any recognisable <strong>for</strong>m. Generally, only sites that have left<br />

significant upstanding remains – such as prehistoric banked enclosures, medieval mottes or<br />

post-medieval field boundaries and agricultural and industrial buildings - survive to any<br />

significant degree. Even then, unless the <strong>for</strong>estry planting has avoided direct effects on the<br />

asset, they are likely to be substantially damaged, while their landscape setting is likely to<br />

have been very largely degraded, not only by the (temporary) screening effect of the<br />

surrounding <strong>for</strong>est but also by the effect of planting on contemporary features in the vicinity.<br />

10.3.46 Effects on historic setting and the wider landscape at Carron Valley need to take into account<br />

not only the immediately surrounding <strong>for</strong>estry but also the construction of the mid-twentieth<br />

century reservoir immediately to the south and the plantation of further <strong>for</strong>estry beyond it.<br />

Within the basin in which the reservoir lies, the historic landscape has been almost entirely<br />

obscured and/or destroyed with the exception of Sir John De Graham’s Castle, Cairnoch<br />

Farm and the Kirk O’Muir graveyard, all of which are very largely isolated from any sense of<br />

their original context. They once <strong>for</strong>med part of a string of agricultural settlements along the<br />

Fintry to Falkirk road, some of which dated back well into the medieval period. Most of these<br />

settlements have now disappeared, their remains either underwater or planted over by<br />

modern <strong>for</strong>estry, while a significant stretch of the old road itself has been submerged.<br />

In<strong>for</strong>mation Gaps<br />

10.3.47 There were no restrictions on access to in<strong>for</strong>mation and there<strong>for</strong>e no gaps within the baseline<br />

presented.<br />

10.4 Topic Specific Design Evolution<br />

10.4.1 The most significant effects of a wind farm on Cairnoch Hill are likely to be on the setting of<br />

historic assets in the area given that any buried remains will have been severely disturbed by<br />

the planting of trees. During the design evolution, most attention was there<strong>for</strong>e given to this<br />

aspect in relation to avoiding significant effects through the evolution of the layout.<br />

10.4.2 The historic asset most sensitive to the proposed wind farm is Sir John De Graham’s Castle,<br />

given that it is a historic landmark of some significance <strong>for</strong> the history of the area as the seat<br />

of the Barony of Dundaff. A secondary consideration was the potential effects on the settings<br />

of the two scheduled barrows on east-facing slopes to the west of the proposals (Figure 10.2;<br />

SM2 & SM3).<br />

10.4.3 A meeting was held at Historic Scotland’s office in Edinburgh on 15 November 2011 to<br />

discuss whether the level of effect of the proposals (at that time <strong>for</strong> a 16 turbine scheme, with<br />

the nearest turbine being just over 200 m from the scheduled area – refer to Figure 10.9b) on<br />

the settings of these designated historic assets was acceptable. Following this meeting, at<br />

the request of Historic Scotland, visualisations were provided demonstrating the visual effect<br />

of the proposals on these assets. Historic Scotland responded by letter dated 7 February<br />

2012 (Appendix 10.5) recommending the removal of the four closest turbines to Sir John De<br />

Graham’s Castle.<br />

10.4.4 As a consequence of this, the western half of the proposed wind farm was redesigned to<br />

mitigate as far as possible effects on the setting of Sir John De Graham’s Castle. The<br />

development was, as a result, reduced to a 15-turbine scheme, with the nearest turbine<br />

located approximately 480 m to the north-east of the scheduled area. The complete removal<br />

of the turbines requested by Historic Scotland would have resulted in two separate groups of<br />

turbines that would have been unacceptable from a technical and visual point of view.<br />

10.4.5 In terms of turbines that affect views from the castle looking along the valley – which is the<br />

most important aspect of its wider setting – the nearest turbine will now be more than 1 km<br />

away. This addressed concerns expressed by Historic Scotland that the original layout would<br />

‘dominate the castle and diminish the sense of the castle on high ground and commanding<br />

the surrounding landscape’ (see Appendix 10.5).<br />

10.4.6 In addition it was proposed that a large, square plantation of Norwegian spruce lying between<br />

the scheduled area and the B818 should be removed as part of the amended Forest Design<br />

Plan (FDP) in order to improve visibility towards and from the Castle (see Chapter 4:<br />

Description of the Proposed Development). A suite of other compensatory measures was<br />

also proposed in order to improve understanding and access to Sir John De Graham’s Castle<br />

<strong>for</strong> the public, including topographical and geophysical survey, sample excavation and the<br />

provision of new on-site in<strong>for</strong>mation signage. The revised proposals were sent, with<br />

supporting illustration, to Historic Scotland by email on 2 March 2012.<br />

10.4.7 The removal of the closest turbines and the opening up of views along the valley means that<br />

the castle’s historic dominance of the local landscape will remain undiminished. The revised<br />

scheme is there<strong>for</strong>e considered the best possible compromise in terms of reducing the effect<br />

of the proposals on the setting of Sir John De Graham’s Castle while maintaining the viability<br />

of the proposed wind farm.<br />

10.4.8 Historic Scotland responded by letter on 16 March 2012 (Appendix 10.6), acknowledging that<br />

the changes do go some way to reducing the effect of the development, while maintaining<br />

that the effects are still significant. It was noted specifically that the revised felling plan would<br />

improve the setting of the monument considerably. It was also stressed that the mitigation<br />

proposals offset rather than reduce the effect of the revised scheme. Consultation with<br />

Historic Scotland is ongoing.<br />

10.4.9 While the magnitude of effect of the intermediate scheme (see Chapter 3: Design Evolution)<br />

on Sir John De Graham’s Castle, with a turbine standing only 200 m east of the monument,<br />

would have been assessed as very large, under the revised proposals it is assessed as large<br />

on a site of restricted sensitivity. The overall effect of the proposals on the setting of the<br />

Castle, which would have been major under the intermediate scheme, is now assessed as<br />

medium on a monument of high importance leading to an assessment of a moderate overall<br />

effect (see paragraph 10.5.19).<br />

10.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

Construction: Direct Physical Effects - Overview<br />

10.5.1 When considering the potential effects of the proposed development upon buried<br />

archaeology it is necessary to consider the extent and degree of disturbance to buried<br />

Carron Valley Wind Farm<br />

remains that will be caused by the development. As discussed in Section 10.3, the actual<br />

degree of survival of any buried archaeology in any of the location affected is likely to be very<br />

low. Given that there are no designated sites within the area of the proposed wind farm, that<br />

remains of non-designated historic sites and features have been substantially destroyed by<br />

<strong>for</strong>estry plantation, and that none of these known sites will be affected by the proposals, the<br />

overall significance of effect on buried archaeology will be negligible or none given that the<br />

sensitivity of all receptors within the <strong>for</strong>estry is at most negligible.<br />

Turbines<br />

10.5.2 Construction of the 21 m-diameter wind turbine foundations to a depth of c3 m, would remove<br />

any archaeological remains that fall within the foundation footprint. Beside each turbine site, it<br />

will be necessary during construction to lay down an area of hard standing, 45 m by 25 m, to<br />

support cranes, requiring a topsoil strip to c0.5 m) and some level of additional cut in<br />

advance. The sloping nature of the site will mean that there will need to be substantial cut in<br />

these areas which will remove any archaeological remains that might survive in these<br />

locations, although none have been identified by this assessment.<br />

Access Tracks<br />

10.5.3 Access tracks to accommodate the vehicles required to carry the turbine components run<br />

wherever possible along existing <strong>for</strong>estry tracks, although tracks leading from the main track<br />

to each proposed turbines will also need to be constructed. The tracks need to be 5 m wide.<br />

Topsoil will be stripped to an approximate depth of up to 0.5 m in advance of construction.<br />

This is likely to disturb any underlying archaeological features that may survive, although<br />

none have been identified by this assessment.<br />

Construction Compound/Control Building<br />

10.5.4 The construction compound and control building will be located immediately inside the site<br />

and will cover an area of approximately 60 m (east-west) by 50 m. This will be cut into the<br />

hillside which will remove any archaeological remains that might survive at this point,<br />

although none have been identified by this assessment. The control building itself will be<br />

10 m x 5 m x 5.5 m high. The construction compound will also contain a concrete batching<br />

plant.<br />

Cabling<br />

10.5.5 Cabling will be laid in trenches c1.1 m deep and 0.6 m wide alongside the access tracks<br />

where possible, connecting the turbines with the control building.<br />

Borrow Pits<br />

10.5.6 Three borrow pit locations have been identified (see Figure 10.1). All are well away from sites<br />

of possible archaeological significance.<br />

Site Drainage<br />

10.5.7 Drainage trenches will be inserted beside all access tracks with drainage pipes flowing<br />

perpendicular to the tracks every 50 m.<br />

Effects on the Site During Operation: Indirect Visual Effects on the Setting of<br />

Historic Assets<br />

10.5.8 The operation of the wind farm would have effects on historic assets resulting from changes<br />

to their settings. There would also be effects on the overall historic landscape.<br />

10.5.9 Likely effects on historic assets resulting from changes to their settings have been assessed<br />

and are described below. Where effects have been assessed as negligible, no further<br />

detailed description is provided. Where this is the case this is generally on the basis of one<br />

of the following reasons:<br />

• although the asset is located within the ZTV, local conditions such as woodland, built<br />

development or microtopography mean that there would not be any intervisibility<br />

between the historic asset and the proposed wind farm; and/or<br />

• the change within the setting of the asset will not lead to any change to the significance<br />

of the asset, or the asset is of negligible or low importance, or a combination of both of<br />

these factors.<br />

10.5.10 The potential <strong>for</strong> effects upon historic assets that fall outside the ZTV was considered but no<br />

such assets were identified.<br />

Designated Sites within 3.5 km of Turbines<br />

Scheduled Monuments<br />

10.5.11 The main consideration in assessing the likely effect of the proposed Carron Valley Wind<br />

Farm on historic assets is its potential effect on the setting of Sir John de Graham’s Castle,<br />

due not only to the importance of the site and its proximity to the development, but also<br />

because most other historic assets in the area have been destroyed as a result of the<br />

construction of the reservoir and the widespread planting of commercial <strong>for</strong>estry in this<br />

section of the Carron Valley.<br />

10.5.12 The other main consideration is the potential effect on scheduled cairns to the north and east<br />

of the proposed site.<br />

Sir John de Graham’s Castle<br />

Definition and Analysis of Setting<br />

10.5.13 In defining and analysing the setting of Sir John de Graham’s Castle, it is necessary to<br />

address the question of how its surroundings ‘contribute to our ability to appreciate and<br />

understand’ the monument. This question can helpfully be broken down further by looking at<br />

i) its immediate surroundings and ii) its wider landscape context.<br />

10.5.14 The scheduled area covers the moated plat<strong>for</strong>m as well as the remains of the post-medieval<br />

house to the north-east. Aerial photographs, especially those taken be<strong>for</strong>e the planting of the<br />

<strong>for</strong>estry around the site in the 1950’s, show a range of features extending beyond this area,<br />

at least some of which are likely to relate to the associated medieval landscape. These<br />

include a variety of earthworks associated with the management and crossing of the streams<br />

that run west and south of the site, a large rectangular enclosure immediately to the northeast<br />

of the site, and a series of linear earthworks to the east and south-east of the site,<br />

perhaps the boundaries of agricultural enclosures associated with the life of the castle<br />

(Figure 10.3). Apart from those features closest to the Castle – which are much less clear<br />

today than they were in the aerial photographs taken in the late 1940’s – the remainder have<br />

now been overtaken by <strong>for</strong>estry and have there<strong>for</strong>e almost certainly been destroyed.<br />

10.5.15 In terms of its wider landscape setting, the features in the local landscape that we can be<br />

reasonably sure existed during the period of the castle’s use are relatively few: the old road,<br />

Kirk O’Muir, the spire of which was probably once visible from the castle, and possibly Fintry<br />

Castle to the west. In addition some of the farmsteads that <strong>for</strong>merly lay along the road to the<br />

east of the castle may well have medieval origins. None of these relationships has endured:<br />

the old road near the castle now lying underwater, there is no trace of the chapel which fell<br />

into ruins some 300 years ago, while any visual connection that might once have existed to<br />

Fintry Castle no longer exists, partly because of the masking effect of the surrounding<br />

<strong>for</strong>estry. Equally the wider landscape has been radically altered, all elements of the historic<br />

landscape in the valley and on the slopes to the south having been removed or obscured by<br />

the reservoir and the <strong>for</strong>estry. The upland pastoralist landscape within which the castle stood<br />

<strong>for</strong> much of the past millennium no longer exists, while the <strong>for</strong>estry enclosing the site impedes<br />

views both towards and away from it.<br />

10.5.16 As the seat of the Barony of Dundaff from at least the twelfth century, the castle was the<br />

feudal centre of the district and its historic location within the landscape reflects this. The<br />

Castle was <strong>for</strong>merly an important local landmark standing at a key strategic point in the<br />

Carron Valley, controlling movement along the east-west road. However, the combination of<br />

the fact that there is no longer a standing building on the site and that it is surrounded by<br />

<strong>for</strong>estry means that this is no longer the case. It can now only be seen from the modern road<br />

(B818) at one point as it passes across the relatively narrow unplanted section of ground<br />

running south from the Castle, and even then only the mound is visible, the moat being<br />

hidden by the slope (see Figure 10.4). From the other side of the reservoir, the site can only<br />

be recognised as a clearance in the <strong>for</strong>est.<br />

10.5.17 Of potential greater significance are the views from the castle, particularly along the valley to<br />

east and west (see Figures 10.5 and 10.6). The views along the valley to the west are<br />

extensive, albeit partially obscured by intervening <strong>for</strong>estry. In other directions, little other than<br />

<strong>for</strong>estry plantation is visible, except to the south where the reservoir and the <strong>for</strong>ested<br />

southern side of the valley can be seen.<br />

Impact Assessment<br />

10.5.18 The revised 15 turbine wind farm layout, designed to minimise effect on Sir John de<br />

Graham’s Castle, locates the closest turbine to the scheduled area (T5) now standing a<br />

minimum of some 480 m away. However this turbine lies to the north-east of the site and will<br />

largely be obscured by existing trees (see Figure 10.7), while the key historic views from the<br />

castle are along the valley to the west and south-east. Views to the west, looking towards<br />

Fintry, will not be affected at all by the proposals. The nearest turbines in views looking along<br />

the valley to the south-east will be T7 over a kilometre away, and, further upslope, T6 over<br />

900 m away. The turbines will be seen over the top of the <strong>for</strong>estry plantation surrounding the<br />

castle, with further <strong>for</strong>estry behind.<br />

10.5.19 The magnitude of effect of the proposed 15 turbine scheme is assessed as large. The<br />

sensitivity of the Castle’s setting can be assessed as restricted, leading to an overall<br />

assessment of the degree of effect on its setting as medium. The overall effect of the<br />

proposals on the setting of the Castle, a monument of high importance, is assessed as<br />

moderate.<br />

10.5.20 This scheduled cairn, most likely to be a Bronze Age burial mound, lies c1 km north-west of<br />

any there might have been are likely to have been destroyed and/or obscured by <strong>for</strong>estry<br />

planting.<br />

Definition and Analysis of Setting<br />

10.5.21 The key elements of the cairn’s surroundings in terms of its setting are its relationships to<br />

nearby remains of the same period: in this case the possible Bronze Age hut circles either<br />

side of the track leading north from Todholes Farm, and other cairns in the area, notably the<br />

one that lies 400 m upslope to the north-west and those at Stronend and on the Gargunnock<br />

Hills, both more than 5 km away.<br />

10.5.22 The cairn is placed in a location that suggests that views towards it were not a major<br />

consideration in its positioning, although outward views, looking along the Carron Valley<br />

towards the west and south-east, were probably important. The landscape will certainly have<br />

changed very substantially since the cairn was originally constructed, with the planting of<br />

commercial <strong>for</strong>estry and the flooding of Carron Valley being notably recent changes. The<br />

existing Earlsburn Wind Farm to the east of the cairn has also changed its setting in recent<br />

years.<br />

Impact Assessment<br />

10.5.23 Although the proposals will represent a change to the setting of the cairn, this change will be<br />

much less significant than it would otherwise have been because of the existence of the<br />

Earlsburn Wind Farm at a similar distance. While the cumulative effect of the two schemes<br />

on its setting will represent a greater effect than the Earlsburn Wind Farm alone, the sense of<br />

a remote upland setting remains largely intact.<br />

10.5.24 The magnitude of effect of the proposed wind farm on Todholes Cairn (Lower) is considered<br />

to be medium, while the sensitivity of the cairn’s setting is considered to be restricted,<br />

indicating a small degree of effect on its setting. The overall significance of effect of the<br />

proposals on the setting of the cairn, a monument of high importance, is there<strong>for</strong>e assessed<br />

as slight.<br />

Todholes Cairn (Upper)<br />

10.5.25 This cairn, again likely to be a Bronze Age burial mound, lies upslope of the cairn described<br />

above, c1.5 km north-west of the nearest proposed turbines (T1 and T5) on the eastern ridge<br />

of the Fintry Hills. It would have a clear view of all of the proposed turbines.<br />

Definition and Analysis of Setting<br />

10.5.26 The key elements of its setting are very similar to those of lower cairn previously discussed. It<br />

is known to be intervisible with scheduled cairns at the western end of Fintry Hills and on the<br />

northern edge of the Gargunnock Hills.<br />

10.5.27 The cairn’s location – on a knoll high above the valley – was clearly not chosen to make it<br />

visible from below. Again outward views seem more important, with its main outlook being<br />

across the low ground around the upper part of Endrick Water, in the area where a series of<br />

potentially contemporary hut circles have been recognised. Its relationship with these<br />

features may well be an important part of its setting there<strong>for</strong>e. As with the lower cairn, the<br />

landscape around has changed to a very great extent over the past 3-4,000 years but<br />

particularly in the past 70 years. The Earlsburn wind farm is slightly closer to this cairn than<br />

the nearest proposed turbine at Carron Valley.<br />

Carron Valley Wind Farm<br />

Assessment of Impact<br />

10.5.28 The proposed turbines in the Carron Valley Forest lie at the same distance from the cairn as<br />

the existing Earls Burn turbines. Given that the cairn retains the key aspects of its upland<br />

setting notwithstanding the existing wind farm, the proposed additional turbines to the south,<br />

within a portion of the landscape that has already seen much change in recent decades, will<br />

not significantly change the setting of this monument.<br />

10.5.29 The magnitude of effect of the proposed wind farm on Todholes Cairn (Upper) is considered<br />

to be medium, while the sensitivity of the cairn’s setting is considered to be restricted. The<br />

degree of effect of the proposals on the setting of the cairn is there<strong>for</strong>e assessed as small.<br />

The overall significance of effect of the proposals on the setting of the cairn, a monument of<br />

high importance, is there<strong>for</strong>e assessed as slight.<br />

Dundaff Hill Mound<br />

10.5.30 This probable prehistoric burial mound lies c3.4 km east of the proposals on the north side of<br />

Dundaff Hill.<br />

Definition and Analysis of Setting<br />

10.5.31 As with the other cairns already described, this cairn is situated on a hill slope in a relatively<br />

discreet location where views out were clearly more important than views towards. This might<br />

relate to Bronze Age settlement in the valley to the north.<br />

Assessment of Impact<br />

10.5.32 Given the relationship of the mound on Dundaff Hill with the lower ground to the north, this<br />

seems more important than views to the west. Views towards the proposed wind farm are<br />

also likely to be screened by trees.<br />

10.5.33 The magnitude of effect of the proposed wind farm on Dundaff Hill Mound is considered to be<br />

small, while the sensitivity of the monument’s setting is considered to be restricted. The<br />

degree of effect of the proposals on the setting of the monument is there<strong>for</strong>e assessed as<br />

small. The overall significance of effect of the proposals on the setting of the castle, a<br />

monument of high importance, is there<strong>for</strong>e assessed as slight.<br />

Listed Buildings<br />

Bentend Steading (Category C)<br />

10.5.34 This nineteenth century, single range block overlooks Carron Valley from the south at a<br />

distance of almost 3.5 km east of the nearest proposed turbines. The ZTV indicates that<br />

between four and seven of the proposed turbines would be visible from the building although<br />

it is partially masked by trees.<br />

Definition and Analysis of Setting<br />

10.5.35 The key aspect of the setting of this farm building lies in its relationship to the surrounding<br />

farmland, in particular the fields in the valley immediately to the north over which it looks. It<br />

does have views looking west down the Carron Valley, although these are oblique and a<br />

secondary aspect of its setting.<br />

Assessment of Impact<br />

10.5.36 Given that the setting of this building is concerned largely with its immediate surroundings,<br />

the proposed development will only have a limited effect on it.<br />

Carron Valley Wind Farm<br />

10.5.37 The magnitude of effect of the proposed wind farm on Bentend Steading is considered to be<br />

small, while the sensitivity of the building’s setting is considered to be notable. The overall<br />

degree of effect of the proposals on the setting of the building is there<strong>for</strong>e assessed as small.<br />

The overall significance of effect of the proposals on the setting of the farm, a building of<br />

medium importance, is there<strong>for</strong>e assessed as slight.<br />

Designated Sites 3.5 – 10 km from Turbines<br />

10.5.38 At distances of greater than 3.5 km from the proposed wind farm, only historic assets of the<br />

highest levels of designation (Scheduled Monuments, Category A & B Listed Buildings and<br />

Registered Parks and Gardens) are assessed. Those where there will be no change in<br />

setting are not discussed.<br />

10.5.39 The setting of the proposed wind farm is unusual in that the site lies in a bowl in the Upper<br />

Carron Valley, limiting visibility of the proposed wind farm to the immediately surrounding hills<br />

and a narrow corridor running down the valley of Endrick Water to the west (see Figure 10.2).<br />

Thus the main area from which the proposals will be visible extends up to 10 km to the west,<br />

3 km to the south, a maximum of 6 km to the north and, albeit substantially screened, <strong>for</strong><br />

around 5 km to the east. Some theoretical visibility starts again c15 km or more to the east,<br />

but at this distance the effects on the historic environment will be negligible.<br />

10.5.40 As a result of these effects of the proposals on designated historic assets beyond 3.5 km is<br />

generally not significant.<br />

10.5.41 The Conservation Area and Category C Listed Buildings at Fintry will not be significantly<br />

affected by the proposals given the combination of their distance from the proposed wind<br />

farm and masking from adjacent built <strong>for</strong>m and trees. The same is true <strong>for</strong> the Scheduled<br />

Monuments that lie on the valley sides to the north and west of the town. For this reason they<br />

are not discussed here in any further detail.<br />

Scheduled Monuments<br />

Fintry Castle<br />

10.5.42 Substantial remains of this <strong>for</strong>mer tower house survive on the lower northern slopes of the<br />

Endrick Water, c4.5 km west of the proposed wind farm. The ZTV suggests that there will be<br />

views of all 15 turbines from here although it is likely that some turbines will be obscured by<br />

the <strong>for</strong>estry.<br />

Definition and Analysis of Setting<br />

10.5.43 The setting of this monument is similar to Sir John de Graham’s Castle in that it stands on a<br />

low rise on the north side of the valley controlling the strategic east-west road. Similarly, it<br />

has an immediate and a wider setting: the immediate setting being the relationship of the<br />

castle to the adjacent streams, tracks and nearby historic settlement, and the wider setting<br />

being its relationship with the valley as a whole, taking in the views to the east and the west.<br />

Impact Assessment<br />

10.5.44 The distance of the turbines to the east of the castle means that their effect on its setting will<br />

be limited. They will not affect its immediate setting. In terms of its wider setting, eastward<br />

views will be affected although the overall strategic dominance the castle has over<br />

approaches from that direction will still be evident. The dominance of the site in the<br />

landscape will remain unaffected.<br />

10.5.45 On this basis, the magnitude of effect of the proposals on the site is considered to be small<br />

on a monument of notable sensitivity, leading to a small degree of effect on the castle’s<br />

setting. The overall significance of effect of the proposals on the setting of the farm, a building<br />

of high importance, is assessed as slight.<br />

Decommissioning<br />

10.5.46 Decommissioning will not result in any significant additional effects on the historic<br />

environment other than removing the operational effects described above.<br />

10.6 Mitigation and Enhancement Measures<br />

10.6.1 Given that the most significant effects of this proposed wind farm on the historic environment<br />

is its effect on the setting of Sir John de Graham’s Castle – as discussed and agreed with<br />

Historic Scotland and the Stirling Council archaeology officer – the mitigation approach has<br />

been focussed on diminishing and offsetting these effects.<br />

10.6.2 Further to the design changes referred to in Section 10.4. In addition, a further series of<br />

enhancement measures have been proposed in discussions with Historic Scotland<br />

addressing the future setting and management of the Castle. A key element of these<br />

proposals, following consultation with Forestry Commission Scotland (FCS), is a proposal to<br />

remove the square plantation of Norwegian spruce that currently lies between the Castle and<br />

Carron Valley Reservoir. This will significantly open up views both from and towards the<br />

castle, going some way to restoring its position within the wider local landscape that has been<br />

obscured in recent decades.<br />

10.6.3 In addition to the proposals having a direct effect on improving the setting of the Castle, a<br />

number of proposals have been put <strong>for</strong>ward addressing its longer-term management. Within<br />

the existing FCS management plan <strong>for</strong> the Castle (Appendix 10.7) concerns are expressed<br />

about the use of the site <strong>for</strong> camping, involving removal of stones from the ruins, the burning<br />

of camp fires within the scheduled area, as well as evidence <strong>for</strong> illicit metal detecting on the<br />

site. While the site is open <strong>for</strong> public access, there is no in<strong>for</strong>mation provided on site, nor is<br />

there anything available on the internet, largely because surprisingly little is known about its<br />

history.<br />

10.6.4 To address these issues the following management changes, agreed in consultation with the<br />

FCS archaeologist, are proposed:<br />

• An aerial photographic and earthworks survey of the Castle and associated features;<br />

• A geophysical survey of the motte and the area to the north-east;<br />

• Targeted sampling of the sedimentary sequence in the motte to retrieve i) dating<br />

evidence <strong>for</strong> the period of its use and ii) an understanding of the changing environment<br />

of the area during the medieval period and subsequently;<br />

• A review of primary historic sources to try to recover a clearer idea of the Castle’s<br />

history;<br />

• An illustrated interpretation panel on the site setting out in an accessible the results of<br />

this research;<br />

• A web-page on the FCS website providing public access to further in<strong>for</strong>mation on this<br />

work and its results.<br />

10.7 Assessment of Residual Effects<br />

10.7.1 Based on the in<strong>for</strong>mation and discussion set out above, the only receptor that could<br />

experience a significant effect from the proposals is Sir John de Graham’s Castle. The<br />

mitigation strategies presented, including through the design evolution process described in<br />

Section 10.4, have reduced the potential overall effect of the proposed wind farm on this<br />

important medieval site to moderate.<br />

10.8 Cumulative Effects<br />

10.8.1 In terms of cumulative effects, significant changes to setting/historic landscape are generally<br />

limited to 3.5 km and, at most, 10 km from a wind farm. For that reason the only significant<br />

cumulative effects in this case are likely to result from the effect of the proposals when<br />

combined with the existing Earlsburn and Craigannet Wind Farms. It also needs to be taken<br />

into account that the Earlsburn North Wind Farm has already been consented. Cumulative<br />

effects of existing and approved schemes on heritage assets affected by the Carron Valley<br />

proposals are considered below.<br />

Sir John de Graham’s Castle<br />

10.8.2 There will be no wider cumulative effects on setting of Sir John de Graham’s Castle in<br />

addition to those described and assessed above as none of the existing or approved<br />

schemes fall are or will be visible from the monument. If the Roseburn application to the west<br />

is taken <strong>for</strong>ward to a full application this is likely to have additional effects on views looking<br />

westwards from the Castle.<br />

Todholes Cairns (Lower and Upper)<br />

10.8.3 The sites most affected will be the scheduled cairns north of Todholes, as well as the nondesignated<br />

remains of prehistoric settlement in the low ground around the upper part of<br />

Endrick Water. The setting of these monuments has already been very substantially<br />

compromised by twentieth century changes to the landscape (the reservoir and commercial<br />

<strong>for</strong>estry). The existing wind farms have significantly altered but not materially damaged their<br />

settings, with the relationships of the monuments to each other and the surrounding<br />

landscape being only marginally affected. The degree of effect on their setting from these<br />

developments is medium (a large effect on monuments of restricted sensitivity). Given their<br />

high importance, the overall effect on their settings is moderate. It is not considered that the<br />

additional turbines proposed under the Carron Valley scheme would significantly alter this<br />

level of effect.<br />

Dundaff Hill Mound<br />

10.8.4 Of the existing wind farms in the area, Dundaff Hill Mound is most significantly affected by<br />

Craigengelt, with the closest turbine standing c.1.7km north-west of the monument, while the<br />

nearest turbine at Earlsburn stands some 5km away. The degree of effect on the setting of<br />

this monument from these developments is small (a small effect on a monument of restricted<br />

sensitivity). Given its high importance, the overall effect on its setting is slight. The additional<br />

turbines proposed under the Carron Valley scheme will be a minimum of 3.4km from this<br />

monument and would not significantly alter this level of effect. Should the Craigannet<br />

application be constructed immediately to the west of Dundaff Hill it would significantly<br />

increase cumulative effects on the setting of this monument.<br />

Bentend Steading (Category C Listed Building)<br />

10.8.5 The Category C Listed Building at Bentend Steading stands c.2.5km south-east of the<br />

nearest turbine at Craigengelt, although views of the turbines are only partial from this valleybottom<br />

location. There are views of the Earlsburn turbines. The degree of effect on the<br />

setting of this monument from Craigengelt is small (a small effect on a monument of<br />

restricted sensitivity). Given its medium importance, the overall effect on its setting is slight.<br />

The additional turbines proposed under the Carron Valley scheme will be a minimum of<br />

3.5km from this monument and would not significantly alter this level of effect. Should the<br />

Craigannet application be constructed immediately on the east of Cairnoch Hill it would<br />

significantly increase cumulative effects on the setting of this monument.<br />

Fintry Castle<br />

10.8.6 At present it is possible to see portions of a number of the turbines at Earlsburn at a distance<br />

of 4.5km or more from Fintry Castle. The degree of effect on the setting of this monument<br />

from Earlsburn is small (a small effect on a monument of notable sensitivity). Given its high<br />

importance, the overall effect on its setting is slight. The additional effect of the Carron Valley<br />

scheme, assessed above, will add slightly to the magnitude of effect but the overall effect on<br />

its setting will remain slight. Should the Kingsburn wind farm, presently in scoping, be<br />

constructed these effects would be significantly greater.<br />

Carron Valley Wind Farm<br />

11 Terrestrial Ecology<br />

11.1 Introduction and Overview<br />

11.1.1 This chapter asses the ecological effects of the proposed wind farm. The assessment<br />

outlines the methodologies used to assess potential effects on internationally, nationally,<br />

regionally and locally protected habitats, flora and fauna (non-avian). An assessment of the<br />

significance of these potential effects is given along with appropriate mitigation measures and<br />

subsequent residual effects. The potential <strong>for</strong> cumulative effects with other associated<br />

developments is also taken into account.<br />

11.1.2 The assessment uses a comprehensive combination of baseline data. This comprises data<br />

gathered via desk study and consultation, and specifically commissioned vegetation and<br />

protected species surveys completed between April 2011 and September 2011 in<br />

accordance with current guidance. These data were also used to highlight ecological<br />

Project Characteristics<br />

11.1.5 The nature of the potential effects of the development are outlined in this section, in relation<br />

to the three main phases: construction, operation and decommissioning. In addition,<br />

cumulative effects are also considered.<br />

11.1.6 In general, the main aspects of the construction, operation and decommissioning of the<br />

proposed wind farm which have the potential to effect upon terrestrial ecological interests<br />

associated with the site are:<br />

• construction and dismantling of works compound, connecting roads and other<br />

temporary structures;<br />

• construction, operation and decommissioning of wind turbines; and<br />

• construction and decommissioning of electrical cable connections.<br />

11.1.7 The potential effects of these activities have been reduced, as far as possible, through the<br />

careful design of the wind farm and site infrastructure, through a joint approach with the<br />

Forestry Commission Scotland (FCS), to minimise the requirement <strong>for</strong> new road<br />

infrastructure and through the use of best-practice construction techniques in the design.<br />

Key Issues<br />

11.1.8 The key potential ecological issues relating to the wind farm are:<br />

• the potential effects on designated sites due to pollution through accidental spillages of<br />

chemicals or fuel and/or increased sedimentation;<br />

• the potential effects on habitats, including Annex 1 and UK priority habitats, through<br />

habitat loss or change;<br />

• the potential effects on European and UK protected species (other than birds) through<br />

disturbance, displacement, habitat fragmentation and risk of injury; and<br />

• the potential effects on other priority habitats and species.<br />

Area (SEPA)<br />

14/10/2011 The site includes watercourses that are within the catchment of the<br />

Endrick Water Special Area of Conservation (SAC), designated <strong>for</strong><br />

Atlantic salmon, brook lamprey and river lamprey. SNH consider that<br />

there is connectivity between the development proposal and the SAC.<br />

The site’s status means that the requirements of the Conservation<br />

(Natural Habitats, &c.) Regulations 1994 as amended apply. SNH<br />

consider that the proposed development is not in connectivity with any<br />

other designated sites.<br />

SNH confirmed that they are content with the scope and<br />

methodologies outlined in the Scoping Report. If peatland vegetation<br />

is identified, further consideration to peat depth on site should be<br />

considered. The presentation of survey results in the <strong>ES</strong> is important;<br />

work should be presented clearly and transparently. It is important to<br />

ensure that surveys are carried out at the right time of year. It is also<br />

helpful if the maps that present vegetation recorded on-site are also<br />

marked with the finalised layout of the wind farm proposal, including<br />

turbines and tracks.<br />

05/01/2012 Confirmed that the scoping report was largely satisfactory, subject to<br />

the detailed advice included in the consultation responses. The<br />

Scoping report on Craigannet Wind Farm should be taken into account<br />

in the <strong>ES</strong>.<br />

11/10/2011 If there are peatland or mire systems present, the <strong>ES</strong> or planning<br />

submission should demonstrate how the layout and design of the<br />

proposal, including any associated borrow pits, hard standing and<br />

roads, avoid impact on such areas where possible. For areas where<br />

avoidance is impossible details of how impact is minimised and<br />

mitigated should be provided, including a detailed map of peat depth<br />

<strong>for</strong> all construction elements that affect peatland habitats.<br />

A Phase 1 habitat survey should be carried out <strong>for</strong> the whole site and<br />

the guidance 'A Functional Wetland Typology <strong>for</strong> Scotland’ (currently<br />

available <strong>for</strong> free download on the SNIFFER website) used to help<br />

identify all wetland areas. National Vegetation Classification should be<br />

carried out <strong>for</strong> any wetlands identified. Results of these findings should<br />

be included in the <strong>ES</strong>, including appropriate maps with the location of<br />

infrastructure clearly marked. If any groundwater dependent terrestrial<br />

ecosystems are located within a radius of (i) 100 m from roads, tracks<br />

and trenches or (ii) 250 m from borrow pits and foundations the likely<br />

impact of these features will require further assessment.<br />

Desk Study<br />

11.2.4 The preparatory work in providing a robust assessment of potentially significant ecological<br />

effects involved interpreting a detailed set of baseline in<strong>for</strong>mation gathered from various<br />

sources. Ecological data on the site itself and its surroundings were collated from a range of<br />

desk based sources, primarily: Scottish Badgers; Scottish Natural Heritage (SNH); British<br />

Bryological Society (BBS); Glasgow Museums Biological Recording Centre (GMBRC);<br />

Buglife; Central Scotland Bat Group (CSBG); Saving Scotland’s Red Squirrels (SSRS);<br />

Stirling Council; Scottish Wildlife Trust (SWT); Scottish Environment Protection Agency<br />

(SEPA); and Botanical Society of the British Isles (BSBI). The relevant data search areas are<br />

outlined in Section 11.3 of this chapter. Copies of consultation responses can be seen in<br />

Appendix 11.1.<br />

11.2.5 Summaries of the results of the desk study are also provided in the appropriate sections<br />

within the ecological baseline descriptions.<br />

11.2.6 In addition to the data requests, the National Biodiversity Network (NBN) was searched <strong>for</strong><br />

additional in<strong>for</strong>mation within the relevant 10 km grid squares covered by the site. With<br />

regards to bats, other published distribution data sources were searched including, the Bat<br />

Atlas (Richardson 2000), Scottish Bats (Haddow & Herman 2000), and Joint Nature<br />

Conservation Committee (JNCC) Article 17 Species Status Assessments (JNCC 2007).<br />

11.2.7 A search was also made <strong>for</strong> all sites with a European, National or Local Authority designation<br />

with an ecological interest (including SACs, SSSIs, and Local Nature Reserves (LNRs)) that<br />

could be affected by the development. This data was collected using SNH’s designated site<br />

datasets, while in<strong>for</strong>mation on these sites was gathered from SNH’s Sitelink website (Figure<br />

11.1). Aerial photography and base maps were used to identify any habitat features of note<br />

within the site and surrounding environs and assess their suitability <strong>for</strong> various relevant<br />

protected species and habitats.<br />

Vegetation Surveys<br />

11.2.8 The site was visited on 11/04/2011, 21/04/2011 and 20/06/2011 and the range of seminatural<br />

habitats within the vegetation survey area as defined in Section 11.3 and shown in<br />

Figure 11.2 were mapped, according to the techniques and definitions described in the<br />

Handbook <strong>for</strong> Phase 1 Habitat Survey (JNCC, 2010). Target notes were made to provide<br />

descriptions of the key habitat features across the site (Appendix 11.2).<br />

NVC Surveys<br />

11.2.9 A targeted NVC survey was undertaken using the results of the Phase 1 Habitat Survey to<br />

identify areas most likely to contain habitats listed on Annex 1 of the Habitats Directive and<br />

wetland habitats. The site was visited on 12/10/2011, and areas of particular botanical<br />

interest within the vegetation survey area (Figure 11.2) were classified and mapped using the<br />

NVC system (Rodwell 1991 et seq.), to NVC sub-community level wherever possible. NVC<br />

polygons and their associated NVC proportions <strong>for</strong> the site are listed in Appendix 11.3.<br />

11.2.10 Some areas within the site did not fit into the NVC nomenclature and, where this occurred,<br />

the area was either given a habitat code using the JNCC Phase 1 Survey methodology<br />

nomenclature (JNCC, 2010), or a prefix <strong>for</strong> the community and the assemblage of species<br />

noted.<br />

11.2.11 Notes were also made about the locations of any plant species of special interest found<br />

during the survey.<br />

11.2.12 Scientific names <strong>for</strong> flora and fauna are given when the species is first mentioned in the text<br />

but not thereafter. Latin binomial system <strong>for</strong> vascular plants follows the nomenclature of<br />

Stace (2007).<br />

Protected Species Surveys<br />

European Protected Species<br />

Otter (Lutra lutra)<br />

11.2.13 Otter surveys were carried out on 19/04/2011 and 28/10/2011 and covered all areas of<br />

suitable habitat (e.g. watercourses, waterbodies and associated terrestrial habitats) within the<br />

site and a 250 m buffer zone of the proposed development (Figure 11.2).<br />

11.2.14 During the survey, evidence of otter presence and activity was recorded and mapped. Otter<br />

field signs are described in Bang and Dahlstrøm (2001) and Sargent and Morris (2003).<br />

Bat Species<br />

11.2.15 Consultation regarding the proposed bat survey methodology outlined below was undertaken<br />

with SNH in May 2011. A detailed description of the survey methodology and dates can be<br />

found in Appendix 11.4.<br />

11.2.16 A series of field surveys were carried out to determine the presence of bat species, estimate<br />

population size, and the level of usage of the site by the bat species. The surveys carried out<br />

are listed below.<br />

Site Walkover<br />

11.2.17 A daytime site walkover was undertaken on 19/04/2011 within the survey area (Figure 11.2).<br />

The aim of this survey was to check and assess the potential value of habitats, features and<br />

structures present <strong>for</strong> roosting, <strong>for</strong>aging and commuting bats.<br />

Roost Surveys<br />

11.2.18 All buildings identified within the bat survey area with the potential to support roosting bats<br />

were inspected externally by an experienced bat ecologist in good weather. This related to<br />

two specific properties: Easter Clingate and Todholes.<br />

11.2.19 Easter Clingate was inspected on 12/10/2011, and evidence of roosting bats recorded. Any<br />

signs of current bat use, signs of historical bat use and/or potential use by bats were<br />

recorded. Ladders, torches and endoscopes were used where necessary. Internal<br />

inspection was not possible as the tenants were not available to provide access. During the<br />

inspection, signs of roosting bats were recorded in two buildings at Easter Clingate. This site<br />

was assessed as having potential <strong>for</strong> bat roosting; there<strong>for</strong>e, a hand-netting survey was<br />

carried out on 24/10/2011. The hand-netting surveys involved locating the egress points of a<br />

known roost and positioning large fine-meshed net outside the roost at dusk be<strong>for</strong>e the bats<br />

have left. In order to ensure any bats leaving are caught no gaps must be left uncovered.<br />

Once bats are caught, the species, age and sex are recorded.<br />

11.2.20 Access to Todholes was denied there<strong>for</strong>e a roost survey was not undertaken at this property.<br />

11.2.21 The site predominantly contained coniferous plantation woodland with a mix of different age<br />

stands. The mature stands are predominantly Sitka spruce with a dense canopy and<br />

there<strong>for</strong>e little potential <strong>for</strong> roosting bats. As no trees supporting, or with the potential to<br />

support roosting bats were identified, no further tree surveys were deemed necessary.<br />

Dusk Commuting Watch Surveys<br />

11.2.22 Dusk commuting watches were undertaken once a month from May to October 2011 to<br />

assess the level of commuting activity to or across the site and to record early emerging, high<br />

risk species such as noctule bats (Nyctalus noctula). Vantage points (VPs) (Figure 11.3) were<br />

located at elevated ground near likely commuting routes in habitat of greater suitability <strong>for</strong><br />

bats.<br />

11.2.23 The surveys started 30 minutes be<strong>for</strong>e sunset and had a duration of 1 hour – 1.5 hours<br />

depending on weather conditions; longer if the night was bright and might delay bat<br />

emergence. Surveyors recorded the flights of any bats observed commuting to/over the site.<br />

Walked Transect Survey<br />

11.2.24 Walked transect surveys (Figure 11.3) were carried once a month from May to October 2011<br />

in order to cover the following key activity periods <strong>for</strong> bats:<br />

• April-May (spring dispersal);<br />

• June-July (maternity season);<br />

• September-October (mating/dispersal season); and<br />

• October-November (dispersal season).<br />

11.2.25 Transects were walked from 45 to 60 minutes after sunset <strong>for</strong> approximately 2 hours. Point<br />

surveys lasting 5 minutes were made along the route. This allowed <strong>for</strong> an assessment of bat<br />

commuting, <strong>for</strong>aging and roosting activity during the dispersal and mating seasons (Natural<br />

England, 2009). Routes and directions varied each month to ensure full coverage of the site<br />

and important habitats, and to avoid temporal bias in the results.<br />

Driven Transect Survey<br />

11.2.26 Driven transect surveys were undertaken following the walked transect or vantage points<br />

surveys on a monthly basis from May to October, to gain an overview of bats using the site<br />

and wider area.<br />

11.2.27 The transect routes (Figure 11.3) were driven with a maximum speed of not more than<br />

15 mph, while an experienced bat surveyor held a Duet bat detector out of the open window<br />

to record any bat passes and species.<br />

Automated Anabat Passive Detector Surveys<br />

11.2.28 Two remote recording bat detectors (Anabats) were positioned at two different locations on<br />

site <strong>for</strong> a two week period during both the maternity and mating/dispersal periods to monitor<br />

bat activity. Anabat detectors were programmed to record all bat activity starting at least one<br />

hour be<strong>for</strong>e sunset until at least one hour after sunrise. The location of the anabat surveys<br />

are shown in Figure 11.3.<br />

Wildcat (Felis silvestris)<br />

11.2.29 Wildcat surveys at the proposed development site were undertaken on 28/10/2011 and<br />

covered all areas of suitable habitat within the protected mammal survey area (Figure 11.2).<br />

11.2.30 The survey involved a site walkover to record any evidence of wildcat within the protected<br />

mammal survey area and to identify any potential den sites <strong>for</strong> wildcats within the survey<br />

area. Rock crevices, rabbit burrows, disused badger setts, areas under fallen debris and old<br />

fox earths were searched <strong>for</strong> evidence of wildcat. This took into consideration Forestry<br />

Commission (FC) Guidance Note 34d (2009).<br />

Great Crested Newt (Triturus Cristatus)<br />

11.2.31 During the Extended Phase 1 Survey, all ponds and waterbodies within the vegetation survey<br />

area (Figure 11.2) were assessed <strong>for</strong> suitability <strong>for</strong> great crested newt.<br />

UK Protected Species<br />

Water <strong>Vol</strong>e (Arvicola aquaticus)<br />

11.2.32 Water vole surveys were undertaken on 28/10/2011 within the protected mammal survey<br />

area (Figure 11.2).<br />

11.2.33 Field signs of water vole were searched <strong>for</strong> using standard methodology, as described in<br />

Strachan and Moorhouse (2006), in areas of potential water vole habitat, e.g. watercourses.<br />

Badgers (Meles meles)<br />

11.2.34 Badger surveys were carried out on 28/10/2011 and 17/02/2011 within all accessible areas of<br />

suitable habitat (e.g. woodland, scrub and field margins) within the protected mammal survey<br />

area (Figure 11.2).<br />

11.2.35 Badger field signs were searched <strong>for</strong> systematically within these areas. Field signs of<br />

badgers are described in Neal and Cheeseman (1996), Bang and Dahlstrøm (2001) and SNH<br />

(2001).<br />

Pine Marten (Martes martes)<br />

11.2.36 As no pine marten field signs were identified during the Extended Phase 1 Habitat survey and<br />

the initial desk study did not identify any pine marten records within the site boundary or a<br />

1km buffer, it was not deemed necessary to undertake a targeted survey. However, due to<br />

the presence of potentially suitable habitat, scats and potential den sites within the protected<br />

mammal survey area (Figure 11.2) were recorded during the NVC survey and protected<br />

mammal surveys.<br />

Red Squirrel (Sciurus vulgaris)<br />

11.2.37 As no red squirrel field signs were identified during the Extended Phase 1 Habitat survey and<br />

the initial desk study did not identify any pine marten records within the site boundary or a<br />

1km buffer, it was not deemed necessary to undertake a targeted red squirrel survey.<br />

However, due to the presence of potentially suitable habitat, feeding signs of squirrel within<br />

the protected mammal survey area (Figure 11.2) were recorded during the NVC survey and<br />

protected mammal surveys.<br />

Reptiles<br />

11.2.38 Although no targeted surveys <strong>for</strong> these species groups were undertaken, all incidental<br />

observations during the Phase 1, NVC survey and the protected species surveys were<br />

recorded.<br />

Freshwater species<br />

11.2.39 Electrofishing surveys were carried out on 03/08/2011, 15/09/2011, 16/09/2011 and<br />

29/09/2011 by the Loch Lomond Fisheries Trust (LLFT). The locations of the survey points<br />

are shown in Figure 11.8. These surveys were undertaken in accordance with the Scottish<br />

Fisheries Co-ordination Centre protocol (SFCC, 2007). Further detail of the methodology can<br />

be found in Appendix 11.5.<br />

Invertebrate species<br />

11.2.40 Although no targeted surveys <strong>for</strong> these species groups were undertaken, all incidental<br />

observations during the Phase 1, NVC survey and the protected species surveys were<br />

recorded.<br />

Limitations of Assessment<br />

11.2.41 It was not possible to undertake an inspection of one property <strong>for</strong> bat roost potential within<br />

the bat survey area as access was denied. Due to a comprehensive desk study and<br />

assessment of bat activity in the local area, it is not considered that this will affect the findings<br />

of the assessment.<br />

11.2.42 The FCS consultation response was received 04/04/2012 following planning and completion<br />

of the protected mammal field survey season in 2011. Subsequently, the field survey suite<br />

and methodology agreed with SNH does not take account of the data provided by FCS. As<br />

the initial desk study findings did not identify any records of pine marten, red squirrel or<br />

wildcat within the site boundary or within a 1km buffer, targeted surveys <strong>for</strong> these species<br />

were not undertaken and instead field signs were recorded during the Phase 1 Habitat<br />

survey, NVC survey and protected mammal survey. Due to the potential low density and<br />

secretive nature of both pine marten and red squirrel, <strong>for</strong>mal surveys <strong>for</strong> these species in this<br />

context are unlikely to confirm absence. There<strong>for</strong>e, although it is considered highly unlikely<br />

that either of these species are present on-site, the impact assessment will use a<br />

precautionary approach. The absence of targeted surveys <strong>for</strong> red squirrel, pine marten and<br />

wildcat is there<strong>for</strong>e not considered to affect the findings of the assessment.<br />

11.2.43 The baseline ecological surveys used to identify relevant Valued Ecological Receptors<br />

(VERs) and to in<strong>for</strong>m the impact assessment are considered to be of an appropriate level of<br />

detail to allow the undertaking of a robust assessment. All seasonally dependent surveys<br />

were undertaken at appropriate times of the year.<br />

The Assessment Process<br />

Valued Ecological Receptors (VERs)<br />

11.2.44 This section details how the significance of effects on ecological receptors is assessed. This<br />

is a staged process based on the IEEM guidelines (2006). Although these guidelines do not<br />

provide a matrix to aid the determination of effect significance, a standard matrix designed <strong>for</strong><br />

this purpose has been produced by RPS and is presented in Table 11.4. This is <strong>for</strong> reasons<br />

of clarity and does not prevent the use of the 2006 guidelines to determine significance<br />

through reasoned argument.<br />

11.2.45 The choice of VERs <strong>for</strong> the site is described in the Evaluation of VERs section, following and<br />

in consideration of the baseline conditions.<br />

Evaluating Biodiversity Assets<br />

11.2.46 Determining the sensitivity of ecological receptors within the study area is undertaken in a<br />

systematic way using criteria that determine their significance. The term used <strong>for</strong> the flora<br />

and fauna of ecological importance that are affected at the site is ‘Valued Ecological<br />

Receptor’. The approach to determining the nature conservation level of each ecological<br />

receptor is outlined in Table 11.2.<br />

11.2.47 In accordance with the IEEM guidelines (2006), the value of habitats is also measured<br />

against published selection criteria. These include size (extent), diversity, naturalness, rarity,<br />

fragility, typicalness, recorded history, position in an ecological or geographical unit, current<br />

condition and potential value.<br />

11.2.48 When assigning a level of value to a species or habitat its distribution and status, including a<br />

consideration of trends based on available historical records, are considered. Rarity is<br />

considered because of its relationship with threat and vulnerability, although rarity in itself is<br />

not necessarily an indicator of value. A species that is rare and declining will be assigned a<br />

higher level of importance than one that is rare but known to be stable.<br />

11.2.49 The potential effects are determined through understanding how each VER responds to the<br />

proposed wind farm. The elements used to define the scale of the effect of a wind farm<br />

include:<br />

• the potential duration, whether short-term (< 5years), medium-term (5-15 years) or<br />

long-term (15-25 years or longer);<br />

• reversibility; whether the effects will be reversible in the short to medium term; and<br />

• whether there are any direct or indirect cumulative effects.<br />

11.2.50 Taking account of these elements, Table 11.3 defines the magnitude of effect <strong>for</strong> VERs.<br />

Definition<br />

Would cause the loss of all, or a major proportion of, a habitat or numbers of species’<br />

population, or cause sufficient damage to immediately affect long-term viability.<br />

Major effects on the feature / population which would have a sufficient effect to alter the<br />

nature of the feature in the short- to long- term and affect its long-term viability.<br />

Effects that are detectable in short and medium-term, but which should not alter the<br />

long-term viability of the feature / population.<br />

Minor effects, either of sufficiently small-scale or of short duration to cause no long-term<br />

harm to the habitat / population.<br />

A potential effect that is not expected to affect the habitat / population in any way.<br />

Assessment of Significant Effects<br />

11.2.51 The significance of the potential effects on each VER is determined by considering the value<br />

of each nature conservation interest and the degree to which it may be affected (the<br />

magnitude of effect) by the proposed wind farm, i.e. by using Table 11.2 and Table 11.3<br />

above. These are described as ‘very substantial’, ‘substantial’, ‘moderate’, ‘slights and<br />

‘negligible’. This is presented as a matrix in Table 11.4.<br />

11.2.52 Some combinations of receptor sensitivity and effect magnitude may vary in the level of<br />

significance depending on the circumstances, which is why some of the cells in Table 11.4<br />

have two levels within them. This allows <strong>for</strong> professional judgement to be applied when<br />

identifying the level of significance.<br />

11.2.53 Effects/residual effects determined as ‘slight’ or ‘negligible’ are not considered to be<br />

significant with regard to the EIA Regulations.<br />

11.3 Baseline In<strong>for</strong>mation<br />

Sources of Data<br />

11.3.1 Data on the important habitats, flora and fauna within the study area were obtained from a<br />

combination of scoping/consultation, desk studies, and field surveys conducted in 2011.<br />

Planning Policy Review<br />

Development Strategy<br />

11.3.2 The study area contains many designations with valued habitats and species. Policy ENV1<br />

of the CSSP sets out criteria to protect and conserve wildlife habitats and other natural<br />

features. Development that has an adverse effect will not be permitted unless it can be<br />

proven that the designation and overall integrity of any area will not be damaged. All<br />

development proposals will be considered in the context of the findings of the Local<br />

Biodiversity Action Plans.<br />

11.3.3 The SCLP identifies the hierarchy of special area designations that contribute to nature<br />

conservation. As defined by Policy POL.E54 the Council will not normally permit or approve<br />

developments or land use changes which may adversely affect:<br />

a) the wildlife interest and conservation management of Local Nature Reserves, nonstatutory<br />

and community nature reserves and fully defined Wildlife Sites; or<br />

b) the integrity or continuity of the landscape features listed below, which are of major<br />

importance <strong>for</strong> wild fauna and flora. Where the reasons in favour of a development<br />

clearly outweigh the desirability of retaining the feature(s), mitigating measures,<br />

including replacement habitat creation will be sought on land within the developers’<br />

control. The features included are linear tree belts, shelterbelts and hedgerows;<br />

plantations and policy woodlands; semi-natural and ancient woodlands; river and<br />

estuary corridors; lochs, reservoirs and ponds; marshland; stone dykes.<br />

11.3.4 Policy POL.E55 of the SCLP addresses the remainder of the hierarchy and advises that:<br />

c) New development will not be acceptable where it is likely to have a significant adverse<br />

effect on the integrity of a Special Protection Area, Special Area of Conservation, or<br />

Ramsar site. The few possible extenuating circumstances are described in SOEnD<br />

Circular 6/1995.<br />

d) Development will not normally be acceptable which is likely to affect an SSSI or NNR,<br />

unless it can be demonstrated that it will not have a significant effect on the special<br />

interest of the site.<br />

PAN 60 - Planning <strong>for</strong> Natural Heritage<br />

11.3.5 PAN 60 does not specifically address wind farm developments but does provide general<br />

guidance on the siting and design of development in relation to Scotland’s natural<br />

environment.<br />

11.3.6 The general principle, as stated in paragraph 52, is that ‘while inappropriate development can<br />

detract from scenic quality or adversely affect particular habitats, species or earth heritage<br />

interests, well designed and carefully sited development can complement the landscape and<br />

substantially increase natural heritage interest’. NPPG 14 (now revoked) stresses that the<br />

scale, siting and design of new development should take full account of the character of the<br />

landscape and the potential impact on the local environment (paragraph 15) (now<br />

encompassed within Paragraph 127 in the SPP). Landscape character assessment can play<br />

a valuable role in in<strong>for</strong>ming the development of a policy framework <strong>for</strong> the siting and design of<br />

new development.<br />

Ballochleam Crags are a line of cliffs and steep slopes which<br />

hold a variety of largely undisturbed and natural habitats<br />

including upland species-rich ledges, unimproved grassland,<br />

heathland and small pockets of woodland. This site holds<br />

several species including early purple orchid(Orchis mascula),<br />

juniper (Juniperus communis), aspen (Populus tremula) and<br />

green spleenwort (Asplenium trichomanes-ramosum) which<br />

are scarce or uncommon within the surrounding landscape.<br />

The designation is based on the presence of alkaline rock<br />

scree flora including Minuartia verna, Anthyllis vulneraria and<br />

early purple orchid.<br />

11.3.9 The northwest corner of the site falls within the catchment area <strong>for</strong> the Endrick Water SAC,<br />

SSSI and Upper Endrick Water LNCS and it is considered that the proposed development<br />

has the potential to impact these designated areas.<br />

11.3.10 Due to the proximity of the proposed Carron Valley Wind Farm to the Endrick Water SAC in<br />

particular, a separate document outlining the potential impacts has been prepared to allow an<br />

appropriate assessment to be made (Appendix 11.6).<br />

11.3.11 Carron Valley Reservoir is a proposed wildlife sites or LNCS which was identified in the late<br />

1980’s, over 20 years ago. This site has not been <strong>for</strong>mally surveyed in the interim and as<br />

such it is unknown what the condition of the notable features are. Given the time period and<br />

provisional nature of the designation, this site is not considered further within this chapter. It<br />

is considered that mitigation measures to protect freshwater habitats on site and the Endrick<br />

Water SAC will prevent any significant effect on Carron Valley Reservoir and the species it<br />

supports.<br />

11.3.12 All other designated sites within the 5 km search buffer are not considered to be in<br />

connectivity with the proposed development due to topography and distance from the site<br />

and as such are not considered further within this chapter.<br />

Coniferous Woodland Plantation<br />

11.3.17 The survey area is dominated by coniferous plantation woodland and contains a mix of<br />

different aged stands. Within the site boundary at the time of survey this habitat covered<br />

227.64ha out of the total site area of 340.6ha. Assuming a build date of 2015 <strong>for</strong> the<br />

proposed wind farm, ongoing <strong>for</strong>estry works will result in 70.41 ha of plantation being felled.<br />

The baseline level of coniferous plantation estimated to be present on site prior to<br />

construction of the wind farm is there<strong>for</strong>e 157.23 ha. The predominant species within the<br />

survey area is Sitka spruce (Picea sitchensis) and lodge-pole pine (Pinus contorta), with<br />

occasional stands of larch species (Larix spp.).<br />

11.3.18 Due to the density of the mature canopy within the site, very little light penetrates the ground<br />

floral layer causing many species to be shaded out; with needle litter there<strong>for</strong>e the dominating<br />

characteristic. As such, throughout the plantation areas, there is little biological diversity<br />

within the floral ground layer.<br />

11.3.19 Within the coniferous plantation there are numerous areas where wind throw has affected the<br />

crop, opening up the predominately closed canopy, allowing a more diverse ground floral<br />

layer to occur. Pleurocarpous mosses such pointed spear-moss (Calliergonella cuspidata),<br />

neat feather-moss (Pseudoscleropodium purum), and red-stemmed feather-moss<br />

(Pleurozium scherberi) have been able to recolonise the needle litter in these areas.<br />

Recently Felled Coniferous Woodland<br />

11.3.20 Throughout the site boundary, a number of the <strong>for</strong>est coupes have recently been clear felled<br />

(99.92 ha) following industry best practice (UKWAS etc). All of these have been restocked.<br />

This technique creates a ‘brash mat’ essential to allow machine access and minimise ground<br />

damage. Assuming a build date of 2015 <strong>for</strong> the proposed wind farm, ongoing <strong>for</strong>estry works<br />

will result in 70.41 ha of additional plantation being clear felled and restocked. The baseline<br />

level of recently felled and largely restocked coniferous woodland is there<strong>for</strong>e estimated to be<br />

170.33 ha.<br />

Carron Valley Wind Farm<br />

11.3.21 Between the brash mats the vegetation is recolonising with an assemblage of acid and<br />

marshy grassland species such as wavy hair-grass (Deschampsia flexuosa), tufted hair-grass<br />

(Deschampsia cespitosa), Yorkshire fog (Holcus lanatus), purple moor grass (Molinea<br />

caerulea), sheep’s and red fescue grasses (Festuca ovina/rubra), and sweet vernal grass<br />

(Anthoxanthum odaratum).<br />

Semi-natural Broadleaved Woodland<br />

11.3.22 Throughout the survey area there are numerous mature and immature broadleaved trees,<br />

including beech (Fagus sylvatica), sycamore (Acer pseudoplatanus), alder (Alnus glutinosa),<br />

silver birch (Betula pendula), downy birch (Betula pubescens), ash (Fraxinus excelsior),<br />

sessile oak (Quercus petraea), penduculate oak (Quercus robur), and rowan (Sorbus<br />

aucuparia).<br />

11.3.23 The largest area of semi-natural broadleaved woodland is located in the west of the<br />

vegetation survey area and covers an area of approximately 9.43 ha, bordering the survey<br />

boundary alongside Endrick Water. This area was previously planted coniferous <strong>for</strong>estry. In<br />

implementing the restructuring of the <strong>for</strong>est this riparian zone is being managed to ensure it<br />

regenerates with native woodland, predominantly birch species in open space, with a<br />

maximum tree height of 6 m. Trees of a greater height follow the boundary of the site in this<br />

area where commercial af<strong>for</strong>estation has not taken place, with the dominant species being<br />

oak and birch.<br />

11.3.24 This habitat was absent from within the site boundary.<br />

Broadleaved Plantation Woodland<br />

11.3.25 A strip of broadleaved plantation runs along the south of the B818 in the southeast of the<br />

vegetation survey area. The plantation covers 0.87 ha of the survey area and was dominated<br />

by sycamore, horse-chestnut (Aesculus hippocastanum) and beech with occasional birch.<br />

This habitat was absent from the site.<br />

Dry Heath/Acid Grassland Mosaic<br />

11.3.26 The largest area of heath within the vegetation survey boundary, is an area of dry heath<br />

covering 17.09 ha located at the summit of Cairnoch Hill which has not undergone<br />

af<strong>for</strong>estation. This habitat is not present within the site boundary. The area is surrounded by<br />

felled <strong>for</strong>estry and existing coniferous plantation <strong>for</strong>estry and thus is likely to have been<br />

affected by the associated <strong>for</strong>estry drainage. Dwarf shrub heath species such as ling heather<br />

(Calluna vulgaris) and blaeberry (Vaccinium mrytillus) occupy less than 30 % of the total<br />

cover, with acidic grassland species such as wavy hair grass dominating the area and as<br />

such the area is classified as a dry heath/acid grassland mosaic. The peat depth across this<br />

area did not exceeded 40 cm.<br />

Semi-improved Acid Grassland<br />

11.3.27 The largest area of semi-improved acid grassland within the survey area is present to the<br />

north of the site boundary and has been heavily grazed by sheep. This area contains a<br />

mosaic of wetter heath communities and scattered bracken. The acid grassland contains<br />

species such as sweet vernal grass, common bent grass (Agrostis capillaris), red fescue, mat<br />

grass (Nardus stricta), and heath bedstraw (Galium saxatile). Towards the south of the area<br />

there is an increase in heath species such as purple moor grass, wavy hair grass, common<br />

sedge (Carex nigra), and hare’s-tail cotton grass (Eriophorum vaginatum).<br />

11.3.28 Within the site boundary, corridors of semi-improved acid grassland are also present along<br />

the <strong>for</strong>est rides and cover an area of 1.61 ha.<br />

Unimproved Neutral Grassland<br />

11.3.29 The clearing around Sir John de Graham’s Castle in the west of the vegetation survey area<br />

covers 4.32 ha and contains a notable grassland mosaic. This habitat is absent from within<br />

the site boundary. The dominant community here is unimproved neutral grassland dominated<br />

by Yorkshire fog and creeping soft grass (Holcus mollis), with small pockets of acid<br />

grassland, including wavy hair-grass and velvet bent grass (Agrostis canina).<br />

Semi-improved Neutral Grassland<br />

11.3.30 Semi-improved neutral grassland areas are present within the site boundary (7.91 ha) in<br />

<strong>for</strong>est rides and are dominated by species such as Yorkshire fog, tufted hair grass, meadow<br />

foxtail (Alopecurus pratensis), annual meadow grass (Poa annua), and smooth meadow<br />

grass (Poa pratensis). The historical burial ground in the southeast of the site also comprised<br />

semi-improved neutral grassland. The desk study confirmed that masterwort, a near<br />

threatened species (2001 IUCN guidelines) and nationally scarce species has historically<br />

been recorded within the burial ground.<br />

Poor Semi-improved Grassland<br />

11.3.31 This habitat is absent from the site but is present in the northwest and east of the vegetation<br />

survey area and covers 149.45 ha. These fields are used <strong>for</strong> grazing and are generally<br />

segregated by wire fencing or drystone walls.<br />

Improved Grassland<br />

11.3.32 The fields to the west of the site boundary are used <strong>for</strong> grazing and comprise of improved<br />

grassland and cover 4.94 ha of the survey area. This habitat is absent from the site.<br />

Marshy Grassland<br />

11.3.33 Marshy grassland covers 29.41 ha of the vegetation survey area, predominantly along the<br />

southern edge adjacent to the reservoir. This strip which runs along the edge of the<br />

reservoir, is a fine mosaic of marshy grassland and acid grassland, with small burns crossing<br />

it and occasional single species stands too small to map (e.g. rosebay willowherb (Epilobium<br />

angustifolium), and reed canary grass (Phalaris arundinacea)). Tufted hair-grass dominates<br />

the marshy grassland, with sweet vernal grass, false oat grass (Arrhenatherum elatius),<br />

marsh thistle (Cirsium palustre) heath woodrush (Luzula multiflora), and reed canary grass all<br />

frequently present. Scattered willow scrub (Salix spp.) borders the reservoir edge.<br />

11.3.34 Around Sir John de Graham’s Castle, areas of marshy grassland and swamp are present<br />

within the remnant defensive earthen dykes contain sharp flowered rush (Juncus acutiflorus),<br />

yellow flag iris (Iris pseudacorus), marsh cinquefoil (Potentilla palustris) and tufted hair grass.<br />

11.3.35 Within the site, marshy grassland is limited to two small clearings in the southwest. The<br />

westernmost of these clearings (TN13) covers 0.374 ha and was identified as a species rich<br />

marshy grassland-swamp-acid grassland mosaic.<br />

Continuous Bracken<br />

11.3.36 Two stands of bracken covering 6.75 ha are present within the semi-improved acid grassland<br />

to the northwest of the site boundary. This habitat is absent from within the site boundary.<br />

Dense Scrub<br />

11.3.37 A small patch of dense scrub covering 0.2 ha comprising of gorse (Ulex europaeus) is<br />

present to the southeast of the site boundary within an area of poor semi-improved grassland<br />

used <strong>for</strong> grazing. This habitat is absent from within the site boundary.<br />

Quarry<br />

11.3.38 Within the site boundary two quarries were identified. The larger quarry in the vegetation<br />

survey area is found on the eastern boundary of the site (TN31). This area contains a<br />

mixture of habitats including abandoned gravel and rubble piles, semi-natural vegetation of<br />

acid grassland and marsh/swamp. The marsh/swamp habitat are a mixture of permanent and<br />

ephemeral with the latter drying out in the summer months. They contain species such as<br />

common spike rush (Eleocharis palustre), hare’s tail cotton grass, jointed rush (Juncus<br />

articulatus), sharp-flowered rush, toad rush (Juncus bufonius), bulbous rush (Juncus<br />

bulbosus), reedmace (Typha sp.), lesser spearwort (Ranuculus flammula), oval sedge (Carex<br />

leporina), cuckoo flower (Cardamine pratensis), and northern marsh orchid (Dactylorhiza<br />

purpurella). The drier areas contain an assemblage of species such as early hair-grass (Aira<br />

praecox), creeping bent grass (Agrostis palustris), heath bedstraw, red fescue, white clover<br />

(Trifolium repens), coltsfoot (Tussilago farfara), and common vetch (Vicia sativa). The<br />

second quarry is situated in the west of the site (TN18) and contains a similar assemblage to<br />

the drier areas noted in the larger quarry.<br />

Standing Water<br />

11.3.39 The dominant water body in the area is the Carron Valley Reservoir bordering the southern<br />

boundary of the site. The reservoir is fed by the River Carron from the west and flows out via<br />

a weir at its eastern tip. The shores of the reservoir are relatively free of emergent vegetation<br />

with only scattered areas of reedmace, soft rush (Juncus effusus), and common spiked rush<br />

being present. This is typical of the drawdown zone around oligotrophic to mesotrophic<br />

reservoirs. Marshy grassland runs along the shore edges, and occasional areas of swamp<br />

are present within sheltered bays.<br />

11.3.40 One pond was identified within the survey area at TN6 to the west of the site boundary. The<br />

fringe of the pond contains emergent vegetation of soft rush. Two small pools of water were<br />

identified within the semi-natural broad–leaved woodland to the west of the site boundary;<br />

however, these were too small to map. The Forestry Commission submitted records from<br />

2008 of two ponds to the northwest of Cairnoch steading, on the southern site boundary.<br />

These were not located during the site visits and are thought to have dried out during the<br />

2011 survey season.<br />

Running Water<br />

11.3.41 The Endrick Water flows through the west of the vegetation survey area (TN5) and at this<br />

point is a swiftly flowing burn approximately 7 m wide. The burn flows over a gravel and<br />

boulder base with a water depth at the time of survey of 40 cm. The banks were<br />

approximately 1m high <strong>for</strong> the length of the burn within the survey area, comprising of a<br />

mixture of brown earth and gley soils.<br />

11.3.42 Earl’s Burn flows through the north eastern corner of the survey area (TN38). At this point the<br />

burn is approximately 4 m wide running over a gravel and boulder base.<br />

11.3.45 This aquatic community is dominant in polygons 4 and 6, both of which contain small water<br />

bodies. The community is dominated by the floating leaves of broad-leaved pondweed<br />

(Potamogetan natans). The community is usually found in association with swamp and mire<br />

communities such as S4 Carex rostrata swamp and M6c Carex echinata – Sphagnum<br />

H12a Calluna vulgaris – Vaccinium myrtillus heath, Calluna vulgaris sub-community<br />

11.3.46 This sub-community is present in mosaics in the north of the survey area which are<br />

dominated by acid grassland communities such as U4 Festuca ovina – Agrostis capillaries –<br />

Galium saxatile grassland, and mire communities such as M20 Eriophorum vaginatum mire.<br />

The H12a community is dominated by mature stands of heather interlaced with blaeberry,<br />

with a groundcover beneath this dominated by bryophytes such as Pleurozium schreberi,<br />

Hypnum jutlandicum, and Hylocomium splendens. Heath bedstraw and tormentil (Potentilla<br />

and 25 within the survey area, in association with acid grass communities such as U2<br />

Deschampsia flexuosa acid grassland, and U4 Festuca ovina – Agrostis capillaris – Galium<br />

saxatile acid grassland.<br />

M6c Carex echinata-Sphagnum fallax/denticulatum mire, Juncus effusus sub-community<br />

11.3.48 This sub-community is found in small proportions throughout the survey area, predominantly<br />

surrounding burns, drainage ditches, and waterbodies. The community is dominated by soft<br />

rush with a mixture of sedges; common sedge, star sedge (Carex echinata), grasses; wavy<br />

hair grass and velvet bent grass, and mosses; common hair-moss (Polytrichum commune)<br />

and Sphagnum fallax, common throughout the soft rush sward.<br />

M6d Carex echinata-Sphagnum fallax/denticulatum mire, Juncus acutiflorus sub-community<br />

11.3.49 The species composition of this sub-community is similar to that of M6c Carex echinata-<br />

Sphagnum fallax/denticulatum mire, Juncus effusus sub-community, however soft rush is<br />

replaced by sharp-flowered rush as the dominant species. As with other M6 subcommunities,<br />

M6d is often found in mosaics containing M25 Molinea caerulea – Potentilla<br />

erecta mire in areas of high water table, and is common throughout the survey area.<br />

M19a Calluna vulgaris – Eriophorum vaginatum blanket mire, Erica tetralix sub-community<br />

11.3.50 This sub-community is found throughout the survey area, usually in mosaics with heath and<br />

mire communities such as M20 Eriophorum vaginatum blanket mire and M6c Carex echinata<br />

– Sphagnum fallax/denticulatum, Juncus effusus sub-community. The community is<br />

dominated by heather and hare’s tail cottongrass which gives the community a distinctive<br />

tussocky appearance. Deer grass (Trichophorum germanicum) and wavy hair-grass are<br />

occasionally found but are not a constant feature, and the ground cover beneath the<br />

dominant vascular species contains frequent Sphagnum capillifolium, Sphagnum papillosum,<br />

Sphagnum tenellum, and Sphagnum fallax. Mosses such as Pleurozium schreberi and<br />

Hypnum, jutlandicum are also abundant in this ground cover.<br />

M20 Eriophorum vaginatum blanket mire<br />

11.3.51 A dominant sward of Hare’s tail cottongrass characterises this community, with ericoid shrubs<br />

having a negligible impact on the foliar cover; heather and blaeberry are only occasionally<br />

present and do not consistently occur throughout the community. Wavy hair-grass, purple<br />

moor grass and common cottongrass (Eriophorum angustifolium) are frequently found<br />

scattered throughout the areas, and Sphagnum mosses and other bryophytes frequently<br />

carpet the ground. This community is often a sign of high grazing pressure where the more<br />

palatable dwarf shrub heath species have been grazed out from the sward leaving only the<br />

tougher, nutrient poor grass species. Within the survey area the community is found most<br />

frequently in the north of the site which is used <strong>for</strong> grazing sheep.<br />

M23 Juncus effusus / acutiflorus rush pasture<br />

11.3.52 This community is dominated by either soft rush within sub-community ‘a’, or sharp-flowered<br />

rush in sub-community ‘b’, with Yorkshire fog, and marsh bedstraw (Galium palustre)<br />

abundantly present. Sweet vernal grass, meadowsweet (Filipendula ulmaria), and lesser<br />

spearwort are also frequently found within the community. The ground cover often contains<br />

frequent mosses, such as Calliergonella cuspidata and Rhytideadelphus squarrosus. Within<br />

the survey area, this community is found most frequently in the north. It is generally the<br />

dominant community within mosaics also contain mire communities, such as M19 Calluna<br />

vulgaris – Eriophorum vaginatum mire, and M20 Eriophorum vaginatum mire.<br />

11.3.53 Within the site, this habitat is only found in the west of the site within the small species rich<br />

clearing of marshy grassland (TN13, Figure 11.4)<br />

M25 Molinea caerulea – Potentilla erecta mire<br />

11.3.54 The presence of purple moor grass with tormentil interlaced with the grass sward<br />

characterises this community, with a negligible moss presence throughout and only<br />

occasional patches of Sphagna present in areas containing a high water table.<br />

11.3.55 Two sub-communities are present throughout the survey area. Sub-community ‘a’ contains<br />

ericoid species such as crossed-leaved heath (Erica tetralix) and heather and within the site<br />

boundary is only located within polygon 31. Sub-community ‘b’ contains a higher species<br />

assemblage of grasses such as sweet vernal grass, sheep’s fescue, and wavy hair-grass and<br />

is absent from the site. Both of these sub-communities are found frequently throughout the<br />

survey area, in particularly within the ride system of the plantation <strong>for</strong>estry.<br />

MG1a Arrhenatherum elatius neutral grassland, Festuca rubra sub-community<br />

11.3.56 The community, typical of deeper richer soils of a more neutral pH, is dominated by false oatgrass,<br />

with frequent cock’s foot (Dactylis glomerata), red fescue, and Yorkshire fog. Small<br />

herbs such as white clover (Trifolium repens), sorrel (Rumex acetosa), and ribwort plantain<br />

(Plantago lancelata) are similarly frequently present in the understorey of the community.<br />

Within the survey area the community is found on the verges surrounding the roads and in<br />

association with other mesotrophic grasslands such as MG9 Holcus lanatus – Deschampsia<br />

cespitosa grassland.<br />

MG9a Holcus lanatus – Deschampsia cespitosa neutral grassland, Poa travialis subcommunity<br />

11.3.57 This grassland is found throughout the survey area and is dominated by tall tussocks of tufted<br />

hair-grass. Within the site it is located in polygons 27, 28 and 33. Grasses such as Yorkshire<br />

fog and sweet vernal grass are also frequently present within the sward, with grasses such as<br />

cock’s foot occasionally seen. Soft rush is frequent throughout these areas, but insufficiently<br />

<strong>for</strong> the areas to be classified as an MG10 Holcus lanatus – Juncus effusus rush pasture.<br />

Rough-stalked meadow grass (Poa trivialis) is frequently present. Scattered herbs such as<br />

creeping buttercup (Ranunculus repens) and marsh thistle are also frequently recorded.<br />

HG9b Holcus lanatus – Deschampsia cespitosa neutral grassland, Arrenatherum elatius subcommunity<br />

11.3.58 This sub-community is similar in its species assemblage to MG9a, however rough-stalked<br />

meadow grass is replaced as a constant by false oat-grass. Within the survey area this subcommunity<br />

is most notably found recolonising the felled areas of <strong>for</strong>estry plantation. Within<br />

the site it is found in NVC polygon 23.<br />

MG10a Holcus lanatus – Juncus effusus rush-pasture, typical sub-community<br />

11.3.59 This community is abundant throughout the survey area, especially in the north and west<br />

surrounding the Endrick Water and Earl’s Burn. Within the site it is present in NVC polygon<br />

29. Areas where the community is found are dominated by soft rush, with Yorkshire fog and<br />

creeping bent grass constantly present throughout, although in varying degrees of<br />

abundance. Creeping buttercup is consistently present in all areas, and rough-stalked<br />

meadow grass is occasionally found. The sub-community is the typical type with no other<br />

characteristic species present. It is often is found within mosaics in association with acid<br />

grassland communities such as U4 Festuca ovina – Agrostis capillaris – Galium saxatile<br />

grassland which are found surrounding many of the waterways in the survey area.<br />

MG10x Holcus lanatus – Juncus effusus rush-pasture, non-NVC sub-community<br />

11.3.60 Soft rush dominates this sub-community of MG10. Unlike the MG10a sub-community, the<br />

ground flora between the soft rush tussocks is dominated by an assemblage of acid<br />

grassland species such as sweet vernal grass, sheep’s fescue, and common bent-grass. This<br />

sub-community is not currently included within the NVC nomenclature but is recognised as a<br />

separate sub-community within MG10 (Averis et al, 2004).<br />

OV27 Epilobium angustafolium community<br />

11.3.61 This community is characterised by the dominant presence of rosebay willowherb and is<br />

usually a characteristic of highly disturbed ground. Within the survey area two subcommunities<br />

are found; sub-community ‘a’ is characterised by ground flora dominated by<br />

Yorkshire fog, whereas sub-community ‘b’ contains an abundance of common nettle amongst<br />

the dominant rosebay willowherb. Both of these sub-communities are found surrounding the<br />

roads throughout the survey area.<br />

S4 Phragmites australis swamp<br />

11.3.62 This community was found occasionally along the shore of the Carron Valley Reservoir on<br />

the southern boundary of the survey area. The community is notable by the dominance of<br />

common reed (Phragmites australis) with few other species present within the reed sward.<br />

Other emergent communities such as S9 Carex rostrata swamp are found in association with<br />

this swamp community.<br />

S9 Carex rostrata swamp<br />

11.3.63 This swamp community is found within the vegetation survey area surrounding a number of<br />

water bodies and in particular in patches along the edge of the Carron Valley Reservoir. The<br />

vegetation is dominated by bottle sedge (Carex rostra), with few other species present, and<br />

often in association with other emergent swamp communities such as S4 Phragmites<br />

australis swamp and M6c Carex echinata-Sphagnum fallax/denticulatum mire, Juncus<br />

effusus sub-community.<br />

U2a Deschampsia flexuosa acid grassland, Festuca ovina – Agrostis capillaris subcommunity<br />

11.3.64 Wavy hair-grass dominates this community with frequent to occasional heather present within<br />

the grass sward. Sweet vernal grass, common bent-grass, and sheep’s fescue are all<br />

frequent present. The community is found in polygons 1 and 11 in association with the<br />

mesotrophic community MG9 Holcus lanatus – Deschampsia cespitosa grassland.<br />

U4a Festuca ovina – Agrostis capillaris – Galium saxatile grassland, typical sub-community<br />

11.3.65 This grassland is characterised by the constant presence of common bent-grass, sweet<br />

vernal grass, sheep’s fescue, heath bedstraw, and common hair-moss, with a carpet of<br />

bryophytes such as Rhytidiadelphus squarrosus covering the ground. There are occasional<br />

patches of heather within this sub-community along with creeping buttercup. The community<br />

is found throughout the north of the survey area in association with the mire communities<br />

M20 Eriophorum vaginatum mire and M19 Calluna vulgaris – Eriophorum vaginatum mire.<br />

U4b Festuca ovina – Agrostis capillaris – Galium saxatile grassland, Holcus lanatus –<br />

Trifolium repens sub-community<br />

11.3.66 As with the U4a sub-community, U4b is defined by the presence of sheep’s fescue, sweet<br />

vernal grass, and common bent-grass, however the frequent presence of Yorkshire fog,<br />

cock’s foot, and occasional crested dog’s tail within the sward is distinctive. Within the survey<br />

area the community is found on damp soils thereby increasing the levels of Yorkshire fog,<br />

with sedges such as star sedge, common sedge, green-ribbed sedge (Carex binervis), and<br />

pill sedge (Carex pilulifera) also frequently found. The sub-community was found in mosaics<br />

throughout the survey area and most commonly associated with areas of mire and other acid<br />

grassland communities.<br />

U4d Festuca ovina – Agrostis capillaris – Galium saxatile grassland, Vaccinium mrytillus –<br />

Deschampsia flexuosa sub-community<br />

11.3.67 This sub-community has a similar species assemblage to that of U4a and U4b, however it is<br />

characterised by the presence of blaeberry throughout the grass sward. Within the survey<br />

area the sub-community is found in polygon 25 at the top of Cairnoch Hill, in association with<br />

the dry heath community H18 Vaccinium mrytillus – Deschampsia flexuosa heath, and M19<br />

Calluna vulgaris – Eriophorum vaginatum mire.<br />

U13a Deschampsia cespitosa – Galium saxatile grassland, Anthoxanthum odoratum subcommunity<br />

11.3.68 This community is characterised by the constant presence of tufted hair-grass and common<br />

bent-grass, with the presence of sweet vernal grass identifying the sub-community. The grass<br />

sward is interlaced with heath bedstraw, with a carpet of pleurocarpous mosses such as<br />

Hylocomium splendens and Rhytidiadelphus loreus. Within the survey area the community is<br />

found within polygon 17 in association with the acid grassland community U4b Festuca ovina<br />

– Agrostis capillaris – Galium saxatile grassland, Holcus lanatus – Trifolium repens subcommunity.<br />

U20 Pteridium aquilinum – Galium saxatile community<br />

11.3.69 This community is characterised by the presence of a bracken sward. Three subcommunities<br />

are found in the survey area, with sub-community ‘a’ characterised by sparse<br />

bracken overlying an acid grassland sward with species such as sweet vernal grass, common<br />

bent-grass, and wavy hair-grass present, whereas sub-community ‘b’ contains blaeberry<br />

amongst the bracken sward. Sub-community ‘c’ is characterised by its dense bracken sward<br />

which shades out most other species, with only occasional Yorkshire fog present within the<br />

bracken leaf-litter. Within the survey area all of these sub-communities are found in the north<br />

of the site on the steeper ground above the Earl’s Burn and the tributaries to the Endrick<br />

Water, in association with the U4 acid grassland communities.<br />

W4b Betula pubescens – Molinea caerulea woodland, Juncus effusus sub-community<br />

11.3.70 This community is characterised by the presence of a downy birch canopy covering a ground<br />

flora dominated by a mixture of tufted hair-grass and purple moor grass, with occasional<br />

patches of Sphagnum fallax in areas of higher water table. The sub-community contains<br />

patches of soft rush, with an increase in the percentage cover of alder and silver birch in the<br />

canopy along with willow saplings. The community is found in the west of the survey area at<br />

polygons 3 and 8.<br />

Holcus lanatus ride<br />

11.3.71 A number of the rides within the <strong>for</strong>estry plantation areas contain a limited number of species<br />

and are dominated by Yorkshire fog, with occasional patches of pleurocarpous mosses<br />

beneath the grass sward. These rides do not fit into the NVC nomenclature; however they are<br />

mentioned due to the frequency in which they were encountered throughout the survey area.<br />

European Protected Species<br />

11.3.72 This section of the chapter describes the results of the surveys to assess the likely presence<br />

of European Protected Species (EPS) (<strong>for</strong> which the UK and Scottish governments have a<br />

responsibility to maintain populations in favourable conservation status).<br />

Otter Survey<br />

Legal Protection<br />

11.3.73 Otters are protected through inclusion in Annex IV of the EC Habitats Directive as translated<br />

into UK law by the Conservation (Natural Habitats, &c.) Regulations 1994 (as amended) as<br />

an EPS. This species is further highlighted as a priority species within the UKBAP and listed<br />

within the Stirling LBAP (2002).<br />

Desk Study<br />

11.3.74 Records provided on the NBN gateway database show records of otters within the site and<br />

the ecology data search area. These records date from between 1977 up to 1995. The<br />

GMBRC holds no records of otter within the ecology data search area. SEPA confirmed the<br />

presence of otters on the Earls Burn and River Carron but do not have any record of otters on<br />

the unnamed tributaries bordering the site.<br />

Field Survey Results<br />

11.3.75 All watercourses and waterbodies were assessed <strong>for</strong> their potential to support otters and are<br />

described in paragraphs 11.7.39 – 11.7.43 within the Phase 1 Habitat survey results.<br />

11.3.76 No otter holts were identified during the survey however two otter couches were identified:<br />

• a couch was recorded under an un-named bridge on the B818 over the Endrick Water.<br />

Otter spraints and mink scats were recorded adjacent to the couch which was located<br />

810 m to west of the site boundary and 1,025 m from the closest turbine (Turbine 5);<br />

and<br />

• a second otter couch with a spraint adjacent to it was identified near a tributary of the<br />

Endrick Water. The couch was located within the site boundary, 234 m to the north of<br />

the closest turbine (Turbine 1).<br />

11.3.77 Otter spraints were identified predominantly on the margins of the protected mammal survey<br />

area, outwith the site boundary. Spraints were concentrated along the Endrick Water and its<br />

tributaries to the west of the site indicating that this waterway is important <strong>for</strong> otter and is<br />

likely to be used <strong>for</strong> <strong>for</strong>aging and commuting. Within the site boundary, there are numerous<br />

small burns that drain into the Earl’s Burn, Endrick Water and Carron Valley Reservoir.<br />

Where these waterways flow through dense conifer plantation, they are considered to present<br />

sub-optimal habitat <strong>for</strong> otters. Towards the margins of the plantation where more clearings<br />

are present, (especially those containing marshy grassland), the waterways have higher<br />

potential <strong>for</strong> otters and may act as commuting corridors and offer some <strong>for</strong>aging potential.<br />

11.3.78 The <strong>for</strong>estry drainage channels which flow through the site were considered to be unsuitable<br />

<strong>for</strong> otters due to their heavily modified, ephemeral nature and poor water quality.<br />

11.3.79 The pond located to the west of the site boundary at TN6 may provide some <strong>for</strong>aging<br />

potential although no otter evidence was identified during the survey.<br />

11.3.80 The areas of marshy grassland along the edge of the Carron Valley Reservoir and within the<br />

site in the <strong>for</strong>est rides provide potential <strong>for</strong>aging habitat <strong>for</strong> otters. During the Phase 1 Habitat<br />

Survey, frogs were present within the species rich marshy grassland at TN13 indicating that<br />

this area could provide a seasonal resource <strong>for</strong> <strong>for</strong>aging otters.<br />

Bat Survey<br />

Legal Protection<br />

11.3.81 All UK bat species are European Protected Species under the EC Habitats Directive, and are<br />

the subject of a UK-wide Biodiversity Action Plan (BAP). They are also protected under<br />

Section 9 of the Wildlife and Countryside Act 1981 as amended by the Nature Conservation<br />

(Scotland) Act 2004. The Conservation (Natural Habitats etc.) Regulations 1994 add further<br />

protection to all bats and their roosts.<br />

11.3.82 The Conservation (Natural Habitats etc.) Amendment (Scotland) Regulations 2007 and the<br />

Conservation (Natural Habitats etc.) Amendment (No.2) (Scotland) Regulations 2009<br />

amended the offences in regard of disturbance to an EPS, including bats, introducing tighter<br />

control on disturbance, obstruction of a roost, or disturbance likely to significantly affect<br />

distribution or abundance and the addition of specific protection <strong>for</strong> hibernating and migrating<br />

bats.<br />

11.3.83 Noctules, soprano pipistrelle and brown long-eared bat (Plecotus auritus) are also highlighted<br />

as priority species within the UKBAP. The Scottish Biodiversity List, which identifies priority<br />

species within Scotland, includes all Scottish bat species, as does the Stirling LBAP (2002).<br />

Desk Study<br />

11.3.84 Published sources of bat distribution data, consultation data shown below and the surveyors’<br />

experience indicated that the following species were likely to be present in the area:<br />

• soprano pipistrelle;<br />

• common pipistrelle (Pipistrellus pipistrellus);<br />

• Daubenton’s bat (Myotis daubentonii);<br />

• Natterer’s bat (Myotis nattereri);<br />

• brown long-eared bat;<br />

• noctule; and<br />

• Nathusius’ pipistrelle.<br />

11.3.85 A search of the NBN gateway database <strong>for</strong> NS68 and NS78 10 km grid squares covering the<br />

site and the surrounding area shows records of common pipistrelle, soprano pipistrelle and<br />

brown long-eared bats. Central Scotland Bat Group similarly returned records <strong>for</strong> common<br />

pipistrelle, soprano pipistrelle and additionally Nathusius’ pipistrelle.<br />

11.3.86 Data search and desk study did not provide records of hibernation sites within the bat data<br />

search area or the high risk bat data search area.<br />

Field Survey Results<br />

11.3.87 The section below summarises the findings of the bat technical report which can be found in<br />

Appendix 11.4.<br />

11.3.88 There are two known roost structures within the bat survey area, both of which were located<br />

more than 500 m from the nearest turbine (Figure 11.7):<br />

• the property at Easter Clingate which is located 1,158 m from the closest turbine<br />

(Turbine 3); and<br />

• a barn owl box which is located 925 m from the closest turbine (Turbine 15).<br />

11.3.89 During the dusk commuting watches, no bats were seen to commute onto or across site.<br />

11.3.90 The walked transect, driven transect and automated Anabat passive detector surveys<br />

identified activity levels ranging from moderate to very low. This is to be expected as the site<br />

is dominated by coniferous woodland and is composed mainly of habitats of low value to<br />

bats. Comparatively higher levels of activity were recorded in the low lying southern area<br />

within the site, alongside the Carron Valley Reservoir (Figure 11.7). In addition, comparatively<br />

higher levels of activity were recorded in the maternity season when compared to the<br />

mating/dispersal period.<br />

11.3.91 Surveys showed that the site is used by a low diversity of species with moderate to very low<br />

activity levels and only two different bat species being recorded. Soprano pipistrelle was most<br />

abundant species, comprising of 70 % of all survey records, followed by common pipistrelle<br />

which made up 12 % of all records. The remaining records were all pipistrelle bats but were<br />

not identifiable to species level, and were thus defined as pipistrellus species.<br />

11.3.92 No hibernation or swarming sites were identified during surveys or the desk study.<br />

Wild Cat<br />

Legal Protection<br />

11.3.93 Wildcats are protected through inclusion in Annex IV of the EC Habitats Directive as<br />

translated into UK law by the Conservation (Natural Habitats, &c.) Regulations 1994 (as<br />

amended) as a European Protected Species (EPS). This species is further highlighted as a<br />

UK BAP priority species and within the Scottish Biodiversity List.<br />

Desk Study<br />

11.3.94 A search of NBN gateway database did not identify records of wildcat within the ecology data<br />

search area. Records provided by FCS identified a wildcat sighting from 2010 approximately<br />

30 m to the east of the site boundary (Figure 11.6). Given the proximity of the site to various<br />

rural residences and Carron Bridge to the east, it is likely that any wildcats records from this<br />

area represent hybrids with domestic cats (Felis catus). As it is not possible to say with<br />

certainty that individuals displaying classic wildcat markings in populated areas are not pure<br />

genetically, they are af<strong>for</strong>ded the same level of protection as pure wildcats.<br />

Field Survey Results<br />

11.3.95 During the Phase 1 Habitat survey, NVC survey and protected mammal field surveys<br />

(targeting suitable habitat <strong>for</strong> badger, otter and water vole) no evidence of wildcat was found.<br />

Disused badger setts or rabbit warrens found on site had the potential to provide potential<br />

denning sites although no evidence of this was recorded at the time of the survey.<br />

Great Crested Newt<br />

Legal Protection<br />

11.3.96 Great crested newts are protected through inclusion in Annex IV of the EC Habitats Directive<br />

as translated into UK law by the Conservation (Natural Habitats, &c.) Regulations 1994 (as<br />

amended) as a European Protected Species (EPS). This species is further highlighted as a<br />

UK BAP priority species and within the Scottish Biodiversity List. Great crested newt is listed<br />

as a priority species in the Stirling LBAP (2002).<br />

Desk Study<br />

11.3.97 A search of NBN gateway database did not identify records of great crested newt within the<br />

ecology data search area. The consultation process did not return any records of great<br />

crested newt within the site or the ecology data search area.<br />

Field Survey Results<br />

11.3.98 During the Extended Phase 1 Habitat Survey a number of waterbodies were identified within<br />

the survey boundary:<br />

• Carron Valley Reservoir – this waterbody is known to contain fish species which<br />

predate on newts and is too large to be considered suitable <strong>for</strong> great crested newts;<br />

• pond at TN6 - this pond was small and heavily shaded with poor water quality.<br />

There<strong>for</strong>e it was not considered suitable <strong>for</strong> great crested newts.<br />

• two small pools in the broadleaved woodland plantation to the west of the site<br />

boundary. These were considered to be ephemeral in nature and not suitable <strong>for</strong> great<br />

crested newts.<br />

11.3.99 Consequently, the likelihood of great crested newts being present on site is considered to be<br />

negligible. As such this species is not considered further within this chapter.<br />

UK Protected Species<br />

Water <strong>Vol</strong>e Survey<br />

Legal Protection<br />

11.3.100 Water voles are protected through Schedule 5 of the Wildlife & Countryside Act 1981 (as<br />

amended), in respect of Section 9(4) only. This species is identified as a priority species<br />

within the UKBAP, the Scottish Biodiversity List and the Stirling LBAP (2002).<br />

Desk Study<br />

11.3.101 The NBN database provided no records <strong>for</strong> this species within the ecology data search area.<br />

The consultation process did not return any records of water vole within the ecology data<br />

search area.<br />

Field Survey Results<br />

11.3.102 All watercourses and waterbodies were assessed <strong>for</strong> their potential to support water vole as<br />

well as <strong>for</strong> the presence of this species.<br />

Carron Valley Wind Farm<br />

11.3.103 The Endrick Water is considered to have low potential <strong>for</strong> water vole due to the fast flowing<br />

nature of the waterway. The surrounding tributaries of the Endrick Water provide some<br />

suitable habitat <strong>for</strong> water vole however no evidence was recorded during the survey.<br />

11.3.104 The waterways in the east of the site were not considered to be suitable <strong>for</strong> water vole due to<br />

the lack of suitable <strong>for</strong>aging habitat in the area and suitable banks <strong>for</strong> burrowing. The<br />

drainage channels within the conifer plantation were considered to be unsuitable due to their<br />

heavily modified, ephemeral nature and poor water quality. No evidence of water voles was<br />

detected along any of the watercourses surveyed.<br />

11.3.105 Mink (Neovison vison) scats and prints were identified within the survey boundary along the<br />

Endrick Water and on one of the tributaries to Carron Valley Reservoir in the southeast of the<br />

site. Mink predate on water vole and the presence of this species is a strong indicator that<br />

water vole are likely to be absent in an area.<br />

11.3.106 Consequently, the likelihood of water voles being present on site is considered to be<br />

negligible. As such this species is not considered further within this chapter.<br />

Badger Survey<br />

Legal Protection<br />

11.3.107 The Protection of Badgers Act 1992 provides full legal protection to badgers. In Scotland,<br />

this legislation was updated by the Nature Conservation (Scotland) Act 2004. SNH interprets<br />

the legislation in such a way that any sett within an active badger territory is af<strong>for</strong>ded legal<br />

protection, whether it shows signs of recent use or not. This species is also listed on the<br />

Scottish Biodiversity List.<br />

Desk Study<br />

11.3.108 Records provided on the NBN gateway database show that badgers have been recorded to<br />

the south of the site within 1 km of the site boundary. The record was from 2006. The FCS<br />

provided one badger record within the ecology data search area. This is discussed in<br />

Appendix 11.7 (Protected Species Confidential Annex).<br />

Field Survey Results<br />

11.3.109 The survey recorded evidence of badger activity within the survey area; this is further detailed<br />

within Appendix 11.7 and Figure TA11.7.1 (confidential).<br />

Pine marten<br />

Legal Protection<br />

11.3.110 Pine marten are protected through Schedule 5 of the Wildlife & Countryside Act 1981 (as<br />

amended). The details of this are further set out in Section 11.2 of this chapter. Any<br />

development works which could affect pine marten may require a licence to legally proceed.<br />

This species is further highlighted as a priority species within the UKBAP.<br />

Desk Study<br />

11.3.111 NBN and GMBRC hold no records of pine marten within the ecology data search area. FCS<br />

provided one record within the ecology data search area of a nest box predated by pine<br />

marten in the northwest corner of the site (Figure 11.6).<br />

11.3.112 The surveyor’s experience has highlighted the presence of pine marten within the local area,<br />

however these sightings all fall outwith the ecology data search area.<br />

Field Survey Results<br />

11.3.113 During the Phase 1 Habitat survey, NVC survey and protected mammal field surveys<br />

(targeting suitable habitat <strong>for</strong> badger, otter and water vole) no evidence of pine marten was<br />

found and no suitable denning sites with signs of occupations were identified.<br />

Red squirrel<br />

Legal Protection<br />

11.3.114 Red squirrel is listed on Schedules 5 and 6 to the Wildlife and Countryside Act, 1981 (as<br />

amended) under Section 9 of the Act. The red squirrel is also listed in Appendix III of the<br />

Bern Convention and is a UK BAP priority species. It is also included on the Scottish<br />

Biodiversity List and in the Stirling LBAP(2002).<br />

Desk Study<br />

11.3.115 Following consultation with Saving Scotland’s Red Squirrels, NBN gateway database was<br />

consulted to determine whether any red squirrel records had been recorded as present within<br />

the vicinity of the site. The NBN gateway database search did not identify any records of red<br />

squirrel on the site or within a 1 km radius. The GMBRC and FCS were also consulted and<br />

did not provide any records of this species within the ecology data search area, though red<br />

squirrels were recorded to the south of the Carron Reservoir, outwith the ecology data search<br />

area.<br />

11.3.116 The surveyor’s experience has highlighted the presence of red squirrel within the local area,<br />

however these sightings all fall outwith the ecology data search area.<br />

Field Survey Results<br />

11.3.117 During the Phase 1 Habitat survey, NVC survey and protected mammal field surveys<br />

(targeting suitable habitat <strong>for</strong> badger, otter and water vole) no evidence of red squirrel was<br />

found within the survey area. The coniferous plantation on site is dominated by Sitka spruce<br />

which is considered to represent a suboptimal food source <strong>for</strong> red squirrel. Consequently,<br />

given the absence of field evidence and records of this species at Carron Valley Wind Farm,<br />

the likelihood of red squirrel being present on site is considered to be low. As such this<br />

species is not considered further within this chapter.<br />

Reptiles<br />

Legal Protection<br />

11.3.118 All species of reptiles native to the UK are protected through Schedule 5 of the Wildlife &<br />

Countryside Act 1981 (as amended), in respect of Section 9(4) only. The following species<br />

are identified as priority species on the UKBAP: slow worm (Anguis fragilis), adder (Vipera<br />

berus) and common lizard (Lacerta vivipara).<br />

Desk Study<br />

11.3.119 A search of the records provided on the NBN gateway database did not identify any records<br />

of reptiles within the ecology data search area. The consultation process did not return any<br />

records of reptiles within the ecology data search area.<br />

Field Survey Results<br />

11.3.120 Forest edges and wide <strong>for</strong>est rides provide good potential habitat <strong>for</strong> reptiles, while <strong>for</strong>est<br />

rides can also provide good connectivity <strong>for</strong> reptiles to commute between suitable habitats.<br />

The quarry habitats (TN18 and TN31) and the clearing around Sir John de Graham’s Castle<br />

(TN10) particularly provide good suitable basking and refuge habitats within the site <strong>for</strong><br />

reptiles.<br />

11.3.121 During the Extended Phase 1 Habitat Survey one pregnant female common lizard was<br />

observed in a clearing in the southwest of the site (TN110).<br />

Freshwater Species<br />

Legal Protection<br />

11.3.122 Atlantic salmon is a species of high conservation concern. It is listed on Annexes II and V of<br />

the EC Habitats Directive and on Schedule 3 of the UK Habitats Regulations 1994. It is a<br />

priority species <strong>for</strong> conservation within the UKBAP, is included on the Scottish Biodiversity<br />

List and the Stirling LBAP (2002).<br />

11.3.123 Brook lamprey are listed on Annex II and river lamprey on Annexes II and V of the EU<br />

Habitats Directive. River lamprey are also on the UKBAP priority list.<br />

11.3.124 Powan (Coregonus Lavaretus) are protected under Schedule 5 of the Wildlife & Countryside<br />

Act 1981 (as amended). Powan is also a priority species under the UK Biodiversity Plan and<br />

included on the Scottish Biodiversity List.<br />

11.3.125 Brown and sea trout (Salmo trutta) are highlighted as a priority species under the UK<br />

Biodiversity Action Plan.<br />

Desk Study<br />

11.3.126 Records provided on the NBN gateway database <strong>for</strong> the ecology data search area show<br />

Atlantic salmon and brown/sea trout have been recorded within the River Endrick. The<br />

records all date from 1990 and were at a 1 km resolution from watercourses to the north and<br />

northwest of the site.<br />

11.3.127 No records of brook or river lamprey were returned within the ecology data search area on<br />

NBN gateway or from the consultees.<br />

11.3.128 Data provided by the Loch Lomond Fisheries Trust confirmed the presence of a refuge<br />

population of powan in Carron Valley Reservoir of Loch Lomond origin.<br />

Field Survey Results<br />

11.3.129 The detailed results of the electrofishing surveys are presented in Appendix 11.5. The<br />

surveys showed that a healthy population of both migratory salmon and trout are present<br />

within the Endrick Water below the falls at Loup of Fintry (sample points EW3 and EW4 – see<br />

Figure 11.8). High densities of under-yearling (age 0+) trout at EW3 indicate that this area is<br />

an important nursery habitat <strong>for</strong> this species. It is also known to be used by spawning<br />

salmon.<br />

11.3.130 Trout were found at all sampling points along the Endrick Water and its tributaries above the<br />

falls at the Loup of Fintry. Salmon were only found at EW2 upstream of the falls. The falls act<br />

as a natural barrier to upstream movement of migratory salmonids. As such, the salmon<br />

upstream of the falls are present due to active stocking by the Loch Lomond Angling<br />

Improvement Association (LLAIA). Stoneloach, minnow and sticklebacks were also found to<br />

be present within the Endrick Water and its tributaries, though all three species were not<br />

found at all locations. Salmon were absent from all sampling points on or adjacent to the site<br />

boundary.<br />

11.3.131 Low densities of brown/sea trout were identified in the Earls Burn. Salmon were absent<br />

during the survey and it is thought that migratory salmonids are absent from this watercourse.<br />

No other species were identified during the surveys.<br />

11.3.132 Three tributaries of the Carron Valley Reservoir were sampled and all three were found to<br />

contain brown/sea trout. High densities of under-yearling trout were present in CV1 and CV2<br />

which indicates that these waterways provide important nursery habitats <strong>for</strong> this species.<br />

Salmon were absent from the tributaries of the Carron Valley Reservoir.<br />

11.3.133 The survey did not identify the presence of river lamprey or brook lamprey. Consequently,<br />

given the absence of field evidence and records of these species at Carron Valley Wind<br />

Farm, the likelihood of river lamprey and brook lamprey being present on site is considered to<br />

be negligible. As such these species are not considered further within this chapter.<br />

Invertebrates<br />

Legal Protection<br />

11.3.139 During the Extended Phase 1 Habitat Survey, 2 small pearl-bordered fritillary were recorded<br />

at TN13 within the marshy grassland habitat.<br />

In<strong>for</strong>mation Gaps<br />

11.3.140 Initial surveys were based on a site boundary and turbine layout provided by the client in<br />

Autumn 2010. Following a review of constraints in May 2011, the site boundary was reduced<br />

in size. This resulted in the survey area exceeding the 250 m buffer of the current application<br />

boundary as such is not considered to negatively impact the assessment.<br />

11.4 Topic Specific Design Evolution<br />

11.4.1 The following buffers were used when designing the layout of the proposed wind farm in<br />

order to protect sensitive features:<br />

• sensitive habitats (including broadleaved woodland, scattered scrub, marshy grassland<br />

and, dry heath acid grassland mosaic) - no wind farm infrastructure placed on these<br />

habitats;<br />

• known watercourses as shown on 1:25,000 OS mapping – 50 m buffer employed<br />

where possible and number of watercourse crossings minimised;<br />

• features used by bats (including watercourses and <strong>for</strong>est edges) –a buffer was used to<br />

ensure a 50 m distance from turbine blade tip to features used by bats as per Natural<br />

England guidelines (2009) (this also applied to <strong>for</strong>est edges that could be created<br />

through removal of <strong>for</strong>estry to facilitate construction). Further details of key-holing<br />

operations are discussed in Chapter 4: Description of the Proposed Development;<br />

• the need <strong>for</strong> new tracks was minimised by utilising existing tracks where possible, to<br />

reduce habitat loss and disturbance;<br />

• wherever possible the layout was designed to minimise the number of watercourse<br />

and drainage channel crossings;<br />

• turbines and access tracks were sited so as to avoid impacts on areas of Annex I<br />

habitats present on the site; and<br />

• all areas identified as containing protected species were buffered at the design stage<br />

by 30 m, with all development sited outside of this.<br />

11.5 Evaluation of Valued Ecological Receptors (VERs)<br />

11.5.1 This section provides an assessment of the nature conservation value of the valued<br />

ecological receptors (VERs) within the site boundary that would be affected by the proposed<br />

wind farm (see Table 11.11). An investigation of the baseline data and current condition of<br />

the site was used to in<strong>for</strong>m the selection of appropriate VERs. Assessments were made <strong>for</strong><br />

those species or habitats considered potentially vulnerable to significant effects and are<br />

described in the Assessment of Effects section below.<br />

11.5.2 The site is located within the SNH Natural Heritage Zone (NHZ) West Central Belt 17. This<br />

appraisal provides an estimate of habitat cover across Scotland and maps several habitat<br />

types as mosaics. These habitats included coniferous plantation, felled woodland, and rough<br />

grassland habitats and any associated mosaics. There<strong>for</strong>e, within West Central Belt NHZ 17<br />

(SNH 2001) there is approximately 79500 ha of the relevant habitats. The proportion of these<br />

11.6 Potential Significant Effects of the Scheme Prior to Mitigation<br />

Construction<br />

11.6.1 The approach used in the assessment of effects has been described in the methodology<br />

section. There are a number of potential effects arising from activities related to the<br />

development of the proposed wind farm that may affect the nature conservation interest of<br />

the area and these are discussed below.<br />

Pollution of Designated Sites<br />

11.6.2 The development of the proposed wind farm has the potential to affect the Upper Endrick<br />

LNCS, Endrick Water SSSI and Endrick Water SAC through water borne pollution into<br />

hydrological systems which link the site to these designated sites; <strong>for</strong> example, through a<br />

fuel, chemical or oil pollution incident and through increased sedimentation and turbidity in<br />

site run off. Within the site, only Turbines 1, 2 and 3 fall within the catchment <strong>for</strong> the Endrick<br />

Water, there<strong>for</strong>e only works relating to these turbines and the immediate surrounding area<br />

will potentially impact the Upper Endrick LNCS, Endrick Water SSSI and Endrick Water SAC.<br />

These designated sites lie 4 km downstream of the site there<strong>for</strong>e the effects of dilution and<br />

settlement of sediment are expected to limit the potential effects of pollution on the<br />

designated sites.<br />

11.6.3 The effect of the development on site hydrology and the effects associated with this are<br />

detailed further in Chapter 13: Hydrology, Hydrogeology and Ground Conditions of this <strong>ES</strong>.<br />

Further in<strong>for</strong>mation on the potential impact upon the SAC is outlined in Appendix 11.6. The<br />

effects below take into consideration the in<strong>for</strong>med design of the development (Chapter 3:<br />

Design Evolution). The potential effect of this pollution is shown below in Table 11.12.<br />

Upper Endrick Water LNCR Low Small Slight<br />

Endrick Water SSSI High Small Moderate<br />

Endrick Water SAC High Small Moderate<br />

Pollution of Terrestrial Habitats<br />

11.6.4 Pollution can arise in the <strong>for</strong>m of fine sediment dusts and sedimentation of surface water<br />

runoff associated with earthworks, as well as from the release of environmentally hazardous<br />

chemicals (e.g. fuels and oils from construction plant). This has the potential to result in the<br />

loss of vegetation and/or alteration of substrate chemistry, which can result in detrimental<br />

changes to vegetation communities in the longer-term. Taking into consideration the<br />

likelihood of this occurring and the limited reach of these possible effects, the potential<br />

magnitude of this effect is assessed as being of a small magnitude. With each habitat on site<br />

considered to be of low sensitivity importance the overall significance of effect is considered<br />

to be slight.<br />

Effects of Pollution on Terrestrial Species<br />

11.6.5 During construction there is the potential <strong>for</strong> protected species to be impacted due to a<br />

variety of types of pollution incidents. Of particular importance is the potential effect on<br />

freshwater species and this is dealt with in the relevant section below.<br />

11.6.6 These impacts also apply to protected mammals, not only having the potential to damage<br />

habitats but also to indirectly affect populations of species, such as otters and bats, through<br />

the alteration of prey resource availability. The potential effect of this pollution on terrestrial<br />

protected species is shown below in Table 11.13. The assessment takes into account the<br />

limited presence of otters within the site boundary and the relatively low levels of bat activity<br />

on the site.<br />

Pollution of Freshwater Habitats and Species<br />

11.6.7 There is the potential <strong>for</strong> watercourses to be impacted during the construction phase by a<br />

variety of pollution types. These include:<br />

• sediment and particulate run off from activities such as earthworks;<br />

• site infrastructure, including site compounds and borrow pits, giving rise to changes in<br />

water turbidity levels, oxygen saturation levels and water pH; and<br />

• chemical spills from various hazardous materials used on site, including fuels and oils.<br />

11.6.8 Where areas of coniferous plantation are felled to facilitate the construction of the proposed<br />

wind farm, this may result in the release of nutrients. This is due to the exposure of organic<br />

material present in the needle beds, disturbance of peat deposits, and the deposition of brash<br />

material during the felling process. The timber will be taken offsite <strong>for</strong> sale and there<strong>for</strong>e<br />

there will be no additional material left on site as a result of mulching practices. As the<br />

majority of turbines are to be situated in areas of woodland already felled during <strong>for</strong>estry<br />

practices and keyholing practices will be used where felling in required, it is considered that<br />

the potential <strong>for</strong> pollution by eutrophication due to felling activities associated with the<br />

proposed wind farm will be low.<br />

11.6.9 The potential magnitude of these effects is influenced by a variety of factors including the flow<br />

levels within the watercourse e.g. pollution during low flows has a higher potential effect than<br />

during high flow periods when greater dilution occurs. There<strong>for</strong>e, <strong>for</strong> the purpose of this<br />

assessment these effects have been assessed taking into account the design elements of the<br />

development including buffering of watercourses from infrastructure and works by at least<br />

50 m.<br />

11.6.10 The potential effect of pollution on freshwater habitats and species is shown below in Table<br />

11.14. This takes into account the presence of potential nursery areas <strong>for</strong> brown/sea trout in<br />

the waterways along the southern edge of the site feeding the Carron Valley Reservoir.<br />

Salmon are only present in the Endrick Water with the closest record, occurring 2.5 km<br />

downstream of the nearest point of influencing works, representing an artificially stocked<br />

population above the falls at Fintry. Within the site, only turbine 1, 2 and 3 fall within the<br />

catchment <strong>for</strong> the Endrick Water, there<strong>for</strong>e only works relating to these turbines and the<br />

immediate surrounding area will potentially effect Atlantic salmon. Further in<strong>for</strong>mation<br />

regarding the potential effects on Atlantic salmon can be found in Appendix 11.6.<br />

Damage and Disturbance to Terrestrial Habitats<br />

11.6.11 Outwith the habitat removal (loss) that will occur to facilitate operation of the wind farm (dealt<br />

with separately under operational effects below), the construction of the wind farm will result<br />

in a degree of habitat disturbance and change in community composition in areas of<br />

construction works post habitat restoration. This can occur through physical damage with<br />

very wet habitats, including marshy grassland, and habitats which occur on very shallow<br />

substrates especially sensitive to disturbance. As the presence of these sensitive habitats is<br />

very limited on site and it is likely that only small amounts of habitats around works areas<br />

would be affected, the overall effect has been assessed accordingly. The potential effect of<br />

this disturbance is shown below in Table 11.15.<br />

Disturbance, Displacement and Injury of Terrestrial Species during Construction<br />

11.6.12 Overall, construction related disturbance would be relatively localised and reasonably shortterm<br />

in nature. There is the potential <strong>for</strong> construction activities on the site to cause<br />

disturbance to protected mammal species present. This can be caused through various<br />

activities including the presence of people on the site causing visual and olfactory<br />

disturbance and from noise and vibration caused by the operation of construction machinery.<br />

Regarding the susceptibility of the receptors to disturbance, otters, bats, wildcat, badgers and<br />

pine marten are predominantly nocturnal and there<strong>for</strong>e most susceptible to early morning and<br />

late evening construction activities. This risk is higher during autumn and winter when<br />

construction activities may overlap with dawn and dusk activity periods of these species.<br />

11.6.13 There is the potential <strong>for</strong> increased mortality of species such as otter, wildcat and pine marten<br />

due to construction traffic on the site. This risk is predominantly a concern during autumn<br />

and winter periods, as highlighted above. Wildlife is also at risk of becoming trapped within<br />

excavations if pipework or excavations are left open over night. If a method of escape is not<br />

provided this can result in injury or death.<br />

11.6.14 With regards to otter and badger, the habitat present represents suboptimal <strong>for</strong>aging habitat,<br />

with more suitable habitat present within the surrounding landscape. As such, the likelihood<br />

of these species being present in the proposed areas of construction is low.<br />

11.6.15 Pine marten and wildcat are likely to use the mature plantation <strong>for</strong>estry predominantly <strong>for</strong><br />

<strong>for</strong>aging <strong>for</strong> small mammals, bird and their nests. These prey sources are most likely to be<br />

found on the <strong>for</strong>est margins and clearings as the dense <strong>for</strong>est interior allows little light to<br />

penetrate the <strong>for</strong>est floor resulting in low overall biodiversity. Where works are carried out<br />

near these areas during early morning and late evening construction activities, there is the<br />

potential to cause disturbance to <strong>for</strong>aging pine marten and wildcat.<br />

11.6.16 The site represents suboptimal habitat <strong>for</strong> <strong>for</strong>aging bats with more suitable habitat present at<br />

the southern site boundary. No significant commuting routes were identified in the site and<br />

the development is assessed as having a negligible effect on commuting bats. No roosts<br />

were found within 500 m of any proposed turbine location, thus the construction phase will<br />

have negligible effect upon local populations of roosting bats.<br />

11.6.17 The specific details relating to the potential <strong>for</strong> disturbance and displacement of badgers due<br />

to the proposed development is dealt with in Appendix 11.7 (confidential).<br />

11.6.18 Reptiles are vulnerable to injury or death during the late autumn and winter when they are<br />

hibernating (i.e. either underground or in other suitable features, such as drystane dykes),<br />

often in large numbers. At this time, they are susceptible to being dug up and/or crushed by<br />

machinery. During their active phase in the spring, summer and early autumn, they are more<br />

able to move away from construction machinery when disturbed. As a result of such<br />

movement, reptiles may be temporarily displaced during the construction phase.<br />

11.6.19 The potential effect of this disturbance is shown below in Table 11.16.<br />

11.6.20 There is the possibility of temporary disturbance to fish populations in the vicinity of<br />

construction activities, through the use of lights and through vibration from plant operation.<br />

However, these effects are likely to be infrequent and temporary with highly mobile fish<br />

species able to disperse from affected areas. With only the locally (low) sensitive brown trout<br />

having been identified within the waterways on the site, the potential effect of these changes<br />

is assessed as being of a small magnitude with an effect of slight significance anticipated.<br />

Operation<br />

Habitat Loss<br />

11.6.21 The turbines and infrastructure associated with the development will result in the loss of<br />

some areas of habitat. These areas have been calculated in accordance with Chapter 4:<br />

Description of the Proposed Development of this <strong>ES</strong> and the results are presented below in<br />

Table 11.17. These figures represent direct habitat loss due to the establishment of the<br />

development infrastructure. Of the dominant NVC communities present within the site<br />

boundary, only M25 is listed as an Annex I habitat. M25 is present within polygon 31 (Figure<br />

11.6.23 The potential effects on the hydrology of the site, are dealt with in Chapter 13: Hydrology,<br />

Hydrogeology and Ground Conditions.<br />

Habitat Loss and Fragmentation <strong>for</strong> Terrestrial Protected Species<br />

11.6.24 The development will not result in the loss of significant habitat <strong>for</strong> the majority of the<br />

protected species detected on the site. For species such as pine marten that use the<br />

plantation <strong>for</strong>estry, the impact will be low as existing <strong>for</strong>estry tracks are to be used <strong>for</strong> access<br />

and key-holing will be used <strong>for</strong> turbine placement where necessary.<br />

11.6.25 The site contains sub-optimal <strong>for</strong>aging habitat <strong>for</strong> otter and badger. Otter activity was limited<br />

to the peripheral edges of the site boundary. The loss of coniferous plantation on site may<br />

improve the <strong>for</strong>aging habitat <strong>for</strong> otters on site by opening up the riparian habitats.<br />

11.6.26 Where key-hole felling is employed, this will increase the area of <strong>for</strong>est edge which may<br />

enhance the potential <strong>for</strong> <strong>for</strong>aging bats, pine marten and reptiles on site. Key-holing will also<br />

create man made glades which may provide sheltered basking areas <strong>for</strong> reptiles.<br />

11.6.27 Where key-hole felling is undertaken around the turbine locations, a buffer of 50 m from the<br />

proposed rotor blade tips to any feature used by bats has been employed. Relevant habitat<br />

features are: <strong>for</strong>estry and woodland canopy edges, water courses, and ponds. Given the<br />

dimensions of the proposed turbines, the calculated minimum recommended distance<br />

between feature and turbine base is 63 m, based on a 14 m maximum tree height. This is in<br />

line with Natural England’s ‘Guidance on Bats and Onshore Wind Turbines’ document (2009).<br />

It is also recommended that habitat close to turbines should be managed to minimise it’s<br />

attractiveness to <strong>for</strong>aging bats: all habitats within 50 m of the turbines blade tips should be<br />

maintained in state which offers poor <strong>for</strong>aging <strong>for</strong> bats: tree and scrub growth to be controlled<br />

to < 1 m; pond <strong>for</strong>mation to be avoided (Entwistle et al 2001). No bat commuting routes were<br />

detected on the site and as such there will be no impact due to fragmentation and habitat loss<br />

<strong>for</strong> commuting bats. No roosts were found within 500 m of any proposed turbine location,<br />

thus the development will have negligible effect upon local populations of roosting bats.<br />

Damage and Disturbance to Freshwater Habitats<br />

11.6.29 The establishment of wind farm infrastructure in or adjacent to watercourses, such as<br />

watercourse crossings, have the potential to cause damage and/or disturbance to aquatic<br />

habitats and species associated with these habitats. This could occur through direct damage<br />

or by indirect means; such as alteration of flow rates, flow regimes or surrounding drainage<br />

mechanisms. There are no new proposed watercourse crossings. Where required, existing<br />

crossings will be upgraded within the development site. These will be designed to be<br />

appropriate to the specific watercourse, taking into account bank stability and the potential<br />

seasonal alterations in flow rates. Outline design/method statements <strong>for</strong> these upgraded<br />

water crossings can be found in Appendix 13.3: Watercourse Crossings Survey. The areas<br />

of habitat loss associated with these crossings will be minimal and the effect has there<strong>for</strong>e<br />

been assessed as shown in Table 11.20 below. The assessment reflects the fact that within<br />

the site boundary, only brown/sea trout was indentified during the electro-fishing surveys and<br />

the presence of two potential nursery areas <strong>for</strong> trout in the waterways draining to the Carron<br />

Valley Reservoir.<br />

watercourse crossing constructed. This aspect has been taken into consideration during the<br />

design process to ensure access is maintained. No new water crossings are proposed and<br />

instead existing water crossings will be upgraded where necessary. Further in<strong>for</strong>mation<br />

relating to the potential water course crossing solutions can be found in Appendix 13.3. The<br />

reflects the fact that within the site boundary, only brown/sea trout was identified during the<br />

Damage, Disturbance and Pollution of Terrestrial Habitats during Maintenance<br />

Activities<br />

11.6.31 There is the potential <strong>for</strong> temporary damage and disturbance to habitats during maintenance<br />

operations and emergency works on the site. This may lead to temporary habitat loss and/ or<br />

permanent habitat degradation. Maintenance operations that require the use of machinery<br />

could result in a pollution incident which may adversely affect the surrounding terrestrial<br />

habitats. Due to the infrequent nature of these works, the low likelihood of this damage<br />

occurring and the likely limited area of any damage, these potential effects are assessed as<br />

being of small magnitude. With terrestrial habitats on site considered to be of low sensitivity<br />

a slight significance is anticipated.<br />

Disturbance, Displacement and Injury of Terrestrial Protected Species during<br />

Maintenance Activities and Operation<br />

11.6.32 During the operational phase of the wind farm there is the potential <strong>for</strong> disturbance to<br />

protected species through human presence on the site during maintenance activities. This<br />

will be at a much reduced frequency and degree compared to the construction phase, and is<br />

most likely to be ongoing within daylight hours. As the species identified at risk from the<br />

development are nocturnal, these works are unlikely to be of disturbance.<br />

11.6.33 The operation of the wind farm is also likely to result in increased levels of noise, vibration<br />

and traffic. However, due to the low levels of these disturbances and low levels of protected<br />

species activity, it is unlikely that there would be a significant effect on the species present on<br />

site.<br />

11.6.34 Given the low sensitivity of species present on site, disturbance during operation is there<strong>for</strong>e<br />

assessed as being of negligible magnitude and negligible significance.<br />

Pollution of Freshwater Habitats and Disturbance of Freshwater Species during<br />

Maintenance Activities<br />

11.6.35 Maintenance activities associated with the operation of the wind farm have the potential to<br />

result in pollution incidences impacting aquatic habitats and associated species. There is<br />

also the potential <strong>for</strong> these activities to result in the disturbance of fish species through noise<br />

and vibration generated through the operation of machinery. Due to the fact that<br />

maintenance activities will be carried out infrequently and be relatively short lived, the risk of<br />

pollution incidences and disturbance is reduced in comparison to the construction phase.<br />

11.6.36 The assessment below takes into account the presence of potential nursery areas <strong>for</strong><br />

brown/sea trout in the waterways along the southern edge of the site feeding the Carron<br />

Valley Reservoir. Salmon are only present in the Endrick Water, with the closest record<br />

occurring 2.5 km downstream of the nearest point of influencing works. Within the site, only<br />

turbine 1, 2 and 3 fall within the catchment <strong>for</strong> the Endrick Water, there<strong>for</strong>e only works<br />

relating to these turbines and the immediate surrounding area will potentially effect Atlantic<br />

salmon. Further in<strong>for</strong>mation regarding the potential effects on Atlantic salmon can be found<br />

in Appendix 11.6.<br />

11.6.37 The potential unmitigated effects of this are shown in Table 11.22 below.<br />

Atlantic salmon Medium Small Slight<br />

Brown/sea trout Low Small Slight<br />

Bat Mortality due to Collision and Barotrauma<br />

11.6.38 During the operation of the wind farm there is the potential <strong>for</strong> bat species to be impacted by<br />

mortality caused by direct collision with the turbine blades, and by barotrauma due to the<br />

decreased (low) air pressure in the wake of rotating turbine blades (Baerwald, 2008). This<br />

can cause damage to soft tissues, such as the lungs, and result in fatal internal bleeding.<br />

11.6.39 The effects of a single bat death is unlikely to be significant on any scale, but cumulative<br />

losses of individual bats could potentially threaten the viability of local or even national<br />

breeding populations. Different species have different flight patterns, flight heights, <strong>for</strong>aging<br />

strategies and echolocation calls and there<strong>for</strong>e have different risk of collision with wind<br />

turbines (Baerwald, et al 2009). Over the survey period only pipistrelle species were<br />

recorded (soprano and common pipistrelle). Natural England (as accepted by SNH),<br />

consider both of these more commonly occurring pipistrelle species to be of medium risk of<br />

collision with wind turbines (Mitchell-Jones and Carlin, 2009).<br />

11.6.40 Most of the areas of proportionally higher bat activity were out-with the proposed turbine<br />

layout (Figure 11.7). However two turbines fall within 100 m of bat records (Turbines 8 and<br />

13) and all turbines fall within 100 m of likely or known bat habitat, whether it be <strong>for</strong>est edge<br />

habitat, <strong>for</strong>est rides or watercourses. Natural England guidance recommends that wind<br />

turbine blade tips should be more than 50 m away from features likely to be used by <strong>for</strong>aging<br />

and commuting bats, such as scrub, trees and waterbodies.<br />

11.6.41 Due to the low level of bat activity and low species diversity, it is considered that the potential<br />

<strong>for</strong> bat mortality at this site falls within the ‘low’ category described by Rydell et al (2010), i.e.<br />

0-3 bats per turbine per year (i.e. up to 45 per annum <strong>for</strong> the site). The lowest reported<br />

European mortality rate is 0.1 bat per turbine per year (Jones et al, 2009). It is considered<br />

that bat activity at the site will remain low, due to the low suitability of habitat, and thus the<br />

likely mortality levels will be nearer the lower end of the range, i.e. 0 – 1 per turbine per year.<br />

With 15 turbines proposed, the total annual mortality at the Carron Valley site is thus<br />

estimated to fall between 1 – 15 bats per year.<br />

11.6.42 This assessment takes into account the considered design of the wind farm as set out in<br />

Chapter 4: Description of the Proposed Development with a separation of 50 m from the tip of<br />

the turbine blade to the <strong>for</strong>est edge, in line with current SNH accepted guidance (Natural<br />

England, 2009). There<strong>for</strong>e, the risk of collision and barotraumas on these species of low<br />

sensitivity is assessed as being of small magnitude and thus slight significance.<br />

Habitat Change<br />

11.6.43 During the construction of the wind farm infrastructure, habitats may undergo change due to<br />

soil disturbance where soils are excavated and subsequently restored, such as around<br />

turbine bases or to create road batters. Areas where temporary construction works are<br />

proposed, such as in laydown areas, will also undergo some degree of temporary<br />

disturbance to habitats. As the habitats on site are dominated by commercial <strong>for</strong>estry, it<br />

should be taken into account that these habitats are already heavily modified from the natural<br />

state. Table 11.23 below shows the areas of calculated habitat change taken into account in<br />

this assessment.<br />

11.6.44 As a result of the construction and establishment of infrastructure across the site, including<br />

turbine bases and access tracks, changes in the hydrological functioning of the site (detailed<br />

further in Chapter 13: Hydrology, Hydrogeology and Ground Conditions) could result in<br />

alterations to habitat composition and structure. The result of these changes can include the<br />

loss of plant species, specifically those adapted to high water levels. The relationship<br />

between the groundwater requirements of habitats and flora is complex, with limited<br />

knowledge of this currently available and as such it is not possible to quantify this effect.<br />

However, research is underway to develop this knowledge relating to the physical<br />

requirements of habitats and flora in relation to water conditions. The only Phase 1 Habitat<br />

category of terrestrial habitat considered particularly sensitive to hydrological changes<br />

present within the site is marshy grassland. In addition, the NVC survey identified a number<br />

of habitats sensitive to hydrological changes, including M6c, M23a and MG10.<br />

11.6.45 The following potential Ground Water Dependant Terrestrial Ecosystems (GWDTE’s) set out<br />

in Table 11.24, as identified in SEPA’ s Landuse Planning System Guidance Note 4 (2010),<br />

were identified as present within the site, with those directly affected by the construction of<br />

the wind farm detailed.<br />

to be heavily modified and of low conservation value. They are also already fragmented due<br />

to the <strong>for</strong>estry practices on site. The findings of Chapter 13: Hydrology, Hydrogeology and<br />

Ground Conditions identify these areas as having no significant aquifers or springs within the<br />

bedrock or superficial soils and as such at Carron Valley these habitats are considered to be<br />

surface water fed. There<strong>for</strong>e, although these habitats are influenced by water levels held<br />

within the soils, they are not dependant on groundwater sources.<br />

11.6.47 There is also the potential <strong>for</strong> windblown pollution from dust generated within the site to<br />

influence species composition of habitats in the long term through the input of nutrients and<br />

alterations to substrate pH.<br />

11.6.48 Due to the small likelihood of these factors occurring, the small proportion of these habitats to<br />

be affected in the context of the site and the limited reach of these possible effects, the<br />

potential effect of these changes on these habitats of low sensitivity is assessed as being of a<br />

small magnitude, and thus of slight significance.<br />

Decommissioning<br />

11.6.49 There may be significant changes in the ecological baseline of the proposed wind farm over<br />

its 25 year operation in comparison to that which currently exists. It is there<strong>for</strong>e not possible<br />

to make a full assessment of the likely effects of the decommissioning phase of the works.<br />

Consequently, this report assumes that similar habitats will prevail and the decommissioning<br />

effects are judged to be of comparable type and of similar or lower magnitude to the<br />

construction phase effects.<br />

11.7 Mitigation and Enhancement Measures<br />

Pre-Construction Mitigation<br />

11.7.1 Prior to commencement of works on site, pre-construction surveys based on existing data <strong>for</strong><br />

protected species will be carried out to check <strong>for</strong> changes in baseline conditions. This will<br />

enable any refinements to be made (if necessary) through micrositing and/or adjustments to<br />

the construction programme to take into account any up-dated distributions or presence of<br />

species.<br />

11.7.2 Surveys will be undertaken within 6 months prior to commencement of the works in order to<br />

obtain as accurate a representation of the baseline conditions as possible. Should this period<br />

of time elapse between pre-construction surveys and the commencement of works then the<br />

need to repeat surveys will be assessed by an ecologist.<br />

Construction Mitigation<br />

11.7.3 All relevant mitigation measures will be implemented through the project Health, Safety and<br />

Environmental Management System (HSEMS) (see Appendix 4.4), which will be prepared in<br />

consultation with, and to the satisfaction of Stirling Council, SEPA and SNH. These will detail<br />

measures such as:<br />

• application of SEPA’ Pollution Prevention Guidance (PPG’s) delimitation of working<br />

areas to minimise damage to habitats;<br />

• a minimum 50 m buffer will be maintained, where possible, between working areas,<br />

machinery and watercourses in all areas except at watercourse crossing points;<br />

• pollution prevention measures will be installed and maintained as appropriate,<br />

including silt interception traps, settling lagoons or mobile silt-trapping units (such as<br />

Siltbusters or equivalent device), as well as installation of splash boards at<br />

watercourse crossing points to prevent contamination from track run-off;<br />

Carron Valley Wind Farm<br />

• chemicals, oils and hazardous materials will be stored in designated areas securely at<br />

a minimum distance of 50 m from the watercourses;<br />

• spillage contingency kits will be provided in all site vehicles and there will be daily<br />

checks <strong>for</strong> oil and fuel leaks;<br />

• application of best practice in relation to the removal and storage of vegetation turfs<br />

and soils to ensure effective reinstatement of vegetation wherever possible;<br />

• application of best practice techniques of track and turbine base construction to ensure<br />

that drainage patterns and water quality within the study area are maintained;<br />

• application of best practice to ensure materials appropriate to site geology are used in<br />

construction activities;<br />

• timing of works to avoid periods of heavy rain when the risk of fine sediment being<br />

transported from earth works is significantly increased. Detailed method statements<br />

relating to pollution prevention and control will be presented in the HSEMS and are<br />

discussed further in Chapter 13: Hydrology, Hydrogeology and Ground Conditions.<br />

11.7.4 Pollution incident response and drainage management measures will be prepared as a part<br />

of the HSEMS to minimise potential pollution effects.<br />

11.7.5 An Ecological Clerk of Works (ECoW) will be present on site to oversee enabling works and<br />

construction. They will be a suitably experienced individual, whose role will ensure works are<br />

carried out in accordance with the HSEMS to ensure compliance with international and<br />

national legislation and planning conditions. The ECoW will also review results of protected<br />

species surveys prior to commencement of works in different areas within the site. Once<br />

works are underway, the ECoW will work on site providing ecological and pollution control<br />

advice and supervision <strong>for</strong> all relevant mitigation measures.<br />

11.7.6 While species such as red squirrel have not been identified within the site boundary, the<br />

potential remains <strong>for</strong> them to move into the site due to their highly mobile nature. As such,<br />

part of the ECoW’s duties will be to provide pre-construction and pre-felling checks <strong>for</strong> all<br />

European Protected Species, water voles, badgers, pine marten, red squirrel and reptiles.<br />

11.7.7 Best practice measures <strong>for</strong> minimising the potential <strong>for</strong> disturbance and injury to protected<br />

species will be employed. These will include:<br />

• covering all trenches, trial pits, excavation and pipelines to prevent animals entering<br />

these holes;<br />

• provision of a method of escape (e.g. a plank) where such excavations cannot be<br />

closed or filled on a nightly basis; and<br />

• vehicle speeds will be restricted across site in order to minimise the risk of collision<br />

with animals.<br />

11.7.8 Removal of the most suitable terrestrial habitats <strong>for</strong> reptiles to be affected by construction<br />

activities, namely in quarry areas to be utilised as borrow pits, will be planned to take place<br />

outside of the hibernation periods <strong>for</strong> these species. The probable low density of reptiles<br />

within the construction areas does not merit specific searches in advance of construction.<br />

Removal of these habitats will be supervised by the ECoW who will halt works where<br />

necessary to allow reptiles to move away from the affected areas.<br />

11.7.9 The mitigation measures outlined in Chapter 13: Hydrology, Hydrogeology and Ground<br />

Conditions <strong>for</strong> protecting watercourses and water bodies will ensure that the pre-construction<br />

quality of watercourses are maintained during and post construction. Where water crossings<br />

are to be upgraded, these will be designed to minimise any disturbance to the watercourse<br />

and geomorphological processes. The structures will not present any barriers to the passage<br />

of migratory fish or other fauna. Further details of the proposed water crossing designs can<br />

be found in Appendix 13.3.<br />

11.7.10 Water quality baseline surveys and subsequent monitoring during the construction phase of<br />

the development will encompass chemical testing, daily visual inspections of waterways by<br />

the ECoW, electrofishing surveys and macroinvertebrate sampling to ensure water quality is<br />

maintained.<br />

11.7.11 Where practicable, reinstatement of habitats will be undertaken around infrastructure. This<br />

will be carried out as the work front progresses, or as soon as is practical after the completion<br />

of the works. The methods of this will be detailed within the HSEMS.<br />

11.7.12 Mitigation measures specific to the protection of badgers on the site are detailed further<br />

within Appendix 11.7 (confidential).<br />

Operation Mitigation<br />

11.7.13 The vehicle speed restrictions stipulated above should also be implemented during the<br />

operation of the wind farm.<br />

11.7.14 Vehicles coming on site will be regularly checked <strong>for</strong> oil leaks to avoid risk of pollution.<br />

Spillage kits will be available on the wind farm site. Best practice methodologies (outlined in<br />

the HSEMS) will be employed during any maintenance works to ensure the prevention of any<br />

pollution to habitats or watercourses, along with implementation of the site pollution incident<br />

response plan and drainage management plan.<br />

11.7.15 A method statement <strong>for</strong> responding to bat corpses should be included in the site operation<br />

procedures. Incidental records of dead bats should be noted and taken into account in the<br />

operation of the site. Consideration should then be given to whether it might be appropriate<br />

to undertake additional survey or monitoring, such as corpse searches.<br />

11.7.16 In line with SNH accepted Natural England guidance, all habitats within 50 m of the turbines<br />

blade tips should be maintained in state which offers poor <strong>for</strong>aging <strong>for</strong> bats.<br />

Decommissioning Mitigation<br />

11.7.17 Best practice measures, as described in the construction stage, will be followed. New<br />

guidance available at the decommissioning phase will be adopted if appropriate.<br />

11.8 Assessment of Residual Effects<br />

11.8.1 The mitigation measures described above are expected to reduce residual effects <strong>for</strong> all<br />

VERs to acceptable levels (‘slight’ or ‘negligible’ significance) in the short and long term.<br />

These are detailed <strong>for</strong> each VER below in Table 11.25.<br />

11.8.2 Providing the mitigation measures proposed are fully implemented, it is predicted there will be<br />

no long-term significant negative effects on any of the locally occurring habitats or species of<br />

importance.<br />

11.9 Cumulative Effects<br />

Potential Sources of Cumulative Effects<br />

11.9.1 This section considers the assessment of cumulative effects on ecological receptors from the<br />

proposed wind farm in combination with effects from other proposed development projects<br />

within the surrounding area. This assessment has considered all development types with the<br />

potential to affect the VERs.<br />

11.9.2 The search area <strong>for</strong> this assessment extends to 5 km from the proposed wind farm site <strong>for</strong> all<br />

VERs with the exception of designated sites i.e. all VERs present within the site boundary.<br />

As the designated sites are located outwith the site boundary, it is considered that all relevant<br />

developments within 5 km of the designated site could effect cumulatively on the Endrick<br />

Water SSSI/SAC. As such, all relevant developments within 5 km of the designated site and<br />

the proposed Carron Valley Wind Farm are considered with regards to designated sites.<br />

The assessment includes projects which are completed, under construction or approved<br />

(Figure 11.9).<br />

11.9.3 There are five wind farms within 5 km of the site boundary which have been considered <strong>for</strong> all<br />

VERs, with the exception of designated sites:<br />

• Earlsburn Wind Farm (operational) Located 2.7 km to the north and consists of 14<br />

turbines;<br />

• Craigannet Wind Farm (application). Located 1.9 km to the east with 6 turbines<br />

proposed;<br />

• Craigengelt Wind Farm (operational). Located 2.8 km to the east and consist of 8<br />

turbines;<br />

• Earlsburn North Wind Farm (approved). Located 4.3 km to the north with 9 turbines<br />

proposed;<br />

• Muirpark Wind Farm (application). Located 4.6 km to the north east with 11 turbines<br />

proposed.<br />

11.9.4 When a 5 km buffer of the Endrick Water SSSI/SAC is considered, there are no additional<br />

development likely to result in cumulative effects. As such, the five wind farms identified<br />

above will be considered <strong>for</strong> all designated site VERs.<br />

Potential Cumulative Effects on Designated Sites<br />

Upper Endrick Water LNCS, Endrick Water SSSI and Endrick Water SAC<br />

11.9.5 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

11.9.6 Craigannet and Craigengelt do not consider the Upper Endrick Water LNCS, Endrick Water<br />

SSSI and Endrick Water SAC as receptors.<br />

11.9.7 Earlsburn North Wind Farm was assessed as having a residual effect of minor significance<br />

on the Endrick Water SAC in respect to loss of integrity of the SAC and pollution or<br />

disturbance.<br />

11.9.8 Muirpark Wind Farm was assessed as having no effect on designated sites.<br />

11.9.9 It is concluded that the development may add cumulatively to the pollution effects on the<br />

Endrick Water LNCS, Endrick Water SSSI and Endrick Water SAC in combination with<br />

Earlsburn North Wind Farm. However, with both developments predicted to have minor<br />

effects upon the river, overall, the cumulative effect is considered to be no greater than slight<br />

overall.<br />

Potential Cumulative Effects on Habitats<br />

11.9.11 Craigannet, Craigengelt, Earlsburn North and Muirpark do not consider coniferous plantation<br />

woodland as a receptor.<br />

11.9.12 It is concluded that the development will not add cumulatively to the effects on this habitat<br />

within the surrounding area.<br />

Semi-improved Acid Grassland<br />

11.9.13 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.14 Craigannet and Craigengelt do not consider this habitat as a receptor.<br />

11.9.15 Earlsburn North is assessed as having an effect of minor significance through the loss of<br />

areas of this habitat during the construction of the site.<br />

11.9.16 Muirpark is assessed as having a minor effect through habitat loss, disturbance and<br />

fragmentation during the construction of the site.<br />

11.9.17 It is concluded that the development will not add cumulatively to the effects on this habitat<br />

within the surrounding area due to the small area of this habitat to be lost.<br />

Semi-improved Neutral Grassland<br />

11.9.18 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

neutral grassland as a receptor.<br />

11.9.20 It is concluded that the development will not add cumulatively to the effects on this habitat<br />

within the surrounding area.<br />

Marshy Grassland<br />

11.9.21 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

mitigation as a result of habitat loss.<br />

11.9.23 Earlsburn North is assessed as having an effect of minor significance on marshy grassland<br />

as a result of habitat loss.<br />

11.9.25 It is concluded that the development will not add cumulatively to the effects on this habitat<br />

within the surrounding area.<br />

Potential Cumulative Effects on Protected Species<br />

11.9.26 The 5 km buffer distance takes into account the ranging distances of protected species<br />

detected on the Carron Valley site and the context and resource of the habitats recorded<br />

within the surrounding area. In north-east Scotland core <strong>for</strong>aging areas of common pipistrelle<br />

have been recorded to extend much further from the roost than <strong>for</strong> soprano pipistrelle (mean<br />

of 1.44 km and 0.69 km respectively) (Harris and Yalden 2008). Otters tend to occupy large<br />

home ranges with males ranging along approximately 32 km of watercourse length and<br />

females ranging 20 km (SNH, 2008). The area this equates to varies greatly depending on<br />

the density of waterways within an area and the availability of prey within the area. While the<br />

habitats within the site boundary were generally assessed as being of low potential <strong>for</strong> otter,<br />

the surrounding area contains a number of good quality waterways and waterbodies with<br />

good <strong>for</strong>aging potential. Badger territories have been recorded to range from c.30 ha<br />

(0.3 km 2 ) in optimal habitat to >150 ha (1.5 km 2 ) in marginal habitats (Harris and Yalden<br />

2008). The habitat types recorded within the Carron Valley site are also present within the<br />

<strong>for</strong>estry plantation to the south of the reservoir. The habitats within the local surrounding<br />

area are generally considered to offer more suitable habitat <strong>for</strong> bats, otters and badgers.<br />

Otter<br />

11.9.27 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.28 The effect of Craigannet on otter through disturbance during construction is assessed as<br />

being not considered to be significant.<br />

11.9.29 Craigengelt Wind Farm is not considered to have a significant effect on otter.<br />

11.9.30 Earlsburn North is not considered to have a significant effect on otters in respect to loss and<br />

or disturbance of otter.<br />

11.9.31 Muirpark Wind Farm is assessed as having a minor effect on otter due to habitat<br />

disturbance, territory severance and altered water quality and quantity.<br />

11.9.32 While the surrounding wind farms were considered to have a minor or negligible effect on<br />

otter, if Carron Valley was to undergo construction as the same time as any of the other<br />

proposed wind farms, cumulatively this may result in an increased disturbance and<br />

displacement of terrestrial species during construction. This potential effect is considered to<br />

be of small magnitude and slight significance.<br />

Bat Species<br />

11.9.33 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.34 Craigangelt, Earlsburn North and Muirpark do no consider bats as receptors.<br />

11.9.35 Craigannet considers there to be no effects on bats in respect of collision risk and<br />

displacement of bats.<br />

11.9.36 It is concluded that there would be a cumulative effect on this species within the surrounding<br />

area with respect to collision risk. This cumulative risk is considered to be of small magnitude<br />

and slight significance within the context of the local bat population.<br />

Badger<br />

11.9.37 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.38 Craigannet is assessed as having no effect on badgers through disturbance from<br />

construction activities or habitat loss.<br />

11.9.39 Craigengelt is considered to have no significant effect on badgers as a results of damage to<br />

setts during construction or loss of <strong>for</strong>aging areas.<br />

11.9.40 Earlsburn North does not consider badgers as a receptor as part of the assessment.<br />

11.9.41 Muirpark Wind Farm is assessed as having a minor effect through indirect disturbance from<br />

construction activities including risk of injury to animals.<br />

11.9.42 Due to the lack of suitable <strong>for</strong>aging habitat and evidence of badger activity within the site<br />

boundary it is concluded that the development will not add cumulatively to the effects on this<br />

species.<br />

Reptiles<br />

11.9.43 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.44 Craigengelt, Earls Burn North and Muirpark do not consider reptiles as receptors.<br />

11.9.45 Craigannet is assessed as having no significant effect on reptiles in respect of potential harm<br />

and disturbance caused during construction.<br />

11.9.46 It is concluded that the development will not add cumulatively to the effects on reptiles within<br />

the surrounding area.<br />

Atlantic Salmon<br />

11.9.47 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

Farm.<br />

11.9.48 Craigannet, Craigengelt and Muirpark do not consider salmon as a receptor.<br />

11.9.49 Earls Burn North is assessed as having an effect of minor significance on salmon through<br />

disturbance. It is concluded that, as salmon were absent from the waterways within the area<br />

of development, the development will not add cumulatively to the effects of disturbance on<br />

salmon.<br />

Brown/Sea Trout<br />

11.9.50 It was not possible to obtain the Environmental <strong>Statement</strong> <strong>for</strong> the existing Earlsburn Wind<br />

11.9.51 Craigannet, Craigengelt, Earls Burn North and Muirpark do not consider trout as a receptor.<br />

11.10.2 This chapter has assessed the likely significance of effects of the development on habitats<br />

and species at the proposed wind farm.<br />

11.10.3 Phase 1 Habitat, NVC and appropriate protected species surveys were undertaken across<br />

the site and the results used to in<strong>for</strong>m the wind farm design and subsequent effect<br />

assessment and mitigation measures.<br />

11.10.4 By applying effective mitigation measures, the residual effects of this development on all<br />

habitats and species are assessed as being ‘slight’ or ‘negligible’ and there<strong>for</strong>e are not<br />

Carron Valley Wind Farm<br />

12 Ornithology<br />

12.1 Introduction and Overview<br />

12.1.1 This Chapter assesses the effects of the proposed wind farm development on birds.<br />

Together with Chapter 11: Terrestrial Ecology it completes the assessment of the effects of<br />

the proposed wind farm development on the natural heritage.<br />

12.1.2 The assessment uses data from specifically commissioned surveys in 2010-2011 and<br />

in<strong>for</strong>mation and data from organisations and individuals with local knowledge who responded<br />

to consultations on the proposed wind farm development, to <strong>for</strong>m a comprehensive<br />

presentation of baseline conditions. Bird names used in this chapter follow the vernacular<br />

names recommended by the British Ornithologists’ Union.<br />

Site Description<br />

12.1.3 The proposed site (approximate central grid reference NS 6970 8550) lies approximately<br />

7 km north of Kilsyth, Central Scotland. Within the site boundary, the habitat is dominated by<br />

coniferous plantation woodland (379.62 ha) containing a mix of different aged stands. The<br />

<strong>for</strong>estry has been subject to increased windblow episodes over recent years. The<br />

surrounding habitat comprises a mixture of open upland moorland and rough grazing, <strong>for</strong>estry<br />

and open water (mainly the Carron Valley Reservoir).<br />

12.1.4 The original development site boundary encompassed the entire Carron Valley Forest (Figure<br />

TA12.1.1, Appendix 12.1) but was substantially reduced in May 2011 following the Initial<br />

Design stage (refer to Chapter 3: Design Evolution). Thus, in May 2011 the site boundary<br />

was altered to exclude the area to the south of the reservoir, so that the proposed<br />

development area became restricted to the <strong>for</strong>est on the north side of the reservoir,<br />

encompassing mainly the land to the south and west of Cairnoch Hill (Figure TA. 12.1.1,<br />

Appendix 12.1). This, and the original site boundaries <strong>for</strong>med the basis of the baseline<br />

surveys carried out in 2010 and 2011. The ornithological study area comprised the<br />

application site boundary and a set of variable buffer zones, depending on each species<br />

group surveyed. A full description of the evolution of the proposed scheme is presented in<br />

Chapter 3: Design Evolution.<br />

12.1.5 The site boundary was again further reduced in March 2012 to provide the current application<br />

site boundary <strong>for</strong> use in the assessment (Figure 12.1). This resulted in the assessment of<br />

ornithological effects being carried out <strong>for</strong> a slightly different study area compared to those<br />

originally surveyed.<br />

12.1.6 Any incomplete spatial survey coverage is however considered to be insignificant in terms of<br />

being able to accurately determine the baseline assemblage present at Carron Valley. This<br />

discrepancy was rectified <strong>for</strong> the flight activity surveys by creating two new vantage points <strong>for</strong><br />

2011 and 2012 surveys which offered complete spatial coverage. For breeding and<br />

wintering bird surveys, the small areas not directly covered are very unlikely to host any<br />

additional target species, particularly with the availability of bird data from a variety of<br />

sources, including nearby wind farm projects with overlapping survey areas.<br />

12.1.7 These aspects are explained in more detail <strong>for</strong> each survey type in the Methodology<br />

Section 12.2, and in the In<strong>for</strong>mation Gaps section of this chapter.<br />

Ornithology


Carron Valley Wind Farm<br />

Predicted Key Issues<br />

12.1.8 The key ornithological issues associated with the proposed wind farm development are likely<br />

to relate to its potential to adversely affect the:<br />

• Conservation status of bird species given the highest level of statutory protection<br />

through inclusion in Annex 1 of the EU Birds Directive and/or Schedule 1 of the Wildlife<br />

and Countryside Act (1981) (as amended) through habitat loss, disturbance,<br />

displacement and collisions with turbines;<br />

• Conservation status of locally-breeding raptors, waders and wildfowl through habitat<br />

loss, disturbance, displacement and collisions with turbines;<br />

• Conservation status of resident raptors during winter, or of passage or wintering geese<br />

and other waterfowl due to the risk of turbine collisions if they fly through the proposed<br />

wind farm development area on migration or while commuting between local feeding<br />

and roosting areas; and<br />

• Ornithological interests of local sites designated <strong>for</strong> bird species.<br />

12.2 Methodology<br />

12.2.1 The methods used are summarised here with more details provided in the relevant sections<br />

below, and in Appendix 12.1. The assessment involved:<br />

• Reference to relevant legislation, policy and guidance;<br />

• Consultation with relevant statutory and non-statutory bodies;<br />

• Detailed desk studies and collation of existing material;<br />

• Site surveys to establish the existing important ornithological interests within the site,<br />

and in its immediate surroundings;<br />

• Evaluation of the potential effects of the proposed wind farm development on important<br />

bird interests both direct and indirectly;<br />

• Evaluation of the significance of effects by consideration of the sensitivity of the<br />

relevant bird interests, the potential magnitude of predicted effects and their probability<br />

of occurring;<br />

• Evaluation of cumulative effects of the wind farm and other projects and activities;<br />

• Identification of appropriate measures to avoid and mitigate against any potential<br />

adverse effects resulting from the proposed wind farm development; and<br />

• Consideration of the residual significance of the predicted effects following mitigation.<br />

12.2.2 Data on important bird populations within the study area were obtained through an extensive<br />

combination of scoping/consultation, desktop studies to collate existing in<strong>for</strong>mation from<br />

sources such as the Scottish Raptor Study Group, the Central Scotland Black Grouse and<br />

Capercaillie Study Group, nearby wind farm projects (e.g. Earlsburn, Craigannet) and newly<br />

commissioned field surveys. The resulting in<strong>for</strong>mation provides ornithological context to the<br />

site and is considered comprehensive, with no shortfalls or in<strong>for</strong>mation gaps that are likely to<br />

significantly affect the robustness of the impact assessment.<br />

12.2.3 The baseline field surveys were undertaken from September 2010 to August 2011, and<br />

augmented in April and May 2012. They there<strong>for</strong>e initially encompassed the initial 77 turbine<br />

layout and site boundary referred to as the Initial Design in Chapter 3: Design Evolution.<br />

These were subsequently amended following the boundary change in May 2011 to reflect the<br />

revised situation. With the exception of the flight activity data, all data presented from the<br />

field surveys refer to the areas within the respective buffers of the final site boundary, and not<br />

to the initial larger proposed development area, unless specifically referenced.<br />

12.2.4 This assessment takes into account the requirements of the following legislation, regulations<br />

and other guidance:<br />

• Council Directive 2009/147/EC on the Conservation of Wild Birds (EU Birds Directive;<br />

the codified version of Directive 79/409/EEC) 1 ;<br />

Consultations<br />

12.2.5 To ensure comprehensive coverage of ornithological issues, key conservation organisations<br />

were consulted during the completion of this assessment.<br />

12.2.6 In September 2011, SNH, RSPB Scotland, Loch Lomond & the Trossachs National Park, and<br />

Stirling, Falkirk, East Dunbartonshire and North Lanarkshire Councils were each sent a<br />

Scoping Report and invited to comment on the ornithological issues surrounding the<br />

proposed development and the suitability of the baseline survey, analysis and assessment<br />

methods proposed.<br />

12.2.7 Details of the relevant Scoping consultation responses received and where the points raised<br />

are addressed within this chapter are presented in Table 12.1 and Table 12.9.<br />

General comments:<br />

SNH is content with the scope and methodologies<br />

presented in the Scoping Report.<br />

A key issue to be addressed within the EIA is the<br />

potential impact on osprey, which are known to nest<br />

at/close to this site.<br />

The <strong>ES</strong> must give careful consideration to the<br />

potential impacts of the proposed windfarm on other<br />

Annex1 / Schedule 1 species that may occur in<br />

proximity to this site, as well as Red-listed Birds of<br />

Conservation Concern and Biodiversity Action Plan<br />

species.<br />

12.5; 12.6; 12.7<br />

12.3; 12.5; 12.6;<br />

12.7<br />

The <strong>ES</strong> needs to provide in<strong>for</strong>mation on any<br />

mitigation measures proposed with respect to<br />

nesting birds. The implications of any change in<br />

land management practice should also be<br />

considered and presented in relation to the bird<br />

species that breed within or use the proposed<br />

windfarm site.<br />

12.6; 12.5.2<br />

Approach and methodology:<br />

Developers should combine three approaches<br />

towards <strong>for</strong>ming a view on the bird populations on a<br />

site and their likely sensitivity:<br />

• Desk-based study of existing in<strong>for</strong>mation.<br />

• Appraisal of habitats and species likely to be<br />

present.<br />

12.2<br />

• Reconnaissance survey.<br />

All bird survey work, analysis and presentation of<br />

Presentation:<br />

It is essential that the record of the survey work<br />

which has been undertaken is presented clearly and<br />

in a transparent manner.<br />

Likewise the full workings of any collision risk<br />

analysis should be presented clearly in an <strong>ES</strong>.<br />

Maps should be clearly laid out, and it is helpful <strong>for</strong><br />

flight-line maps and <strong>for</strong> maps recording the locations<br />

of breeding birds to be also marked with the<br />

finalised windfarm layout.<br />

It is possible that a confidential annex may be<br />

required in relation to the distribution of vulnerable<br />

12.2.8 In accordance with SNH guidance (SNH 2006), the desk study, field surveys and impact<br />

assessment were all focused on bird species of conservation importance. For the proposed<br />

wind farm, species were regarded as being of conservation importance if they were at least<br />

one of the following:<br />

• Bird species listed on Annex 1 of the EU Birds Directive;<br />

• Bird species listed on Schedule 1 of the Wildlife and Countryside Act 1981 (as<br />

amended);<br />

• Bird species that are qualifying features of the conservation designated sites within up<br />

to 20 km of the proposed development;<br />

• Regularly-occurring migratory species where the UK holds an internationally-important<br />

proportion of the European population;<br />

• Bird species that are Red- or Amber-listed in the UK’s Birds of Conservation Concern<br />

(BoCC) (Eaton et al. 2009);<br />

• Bird species identified as priorities on the UKBAP; and/or<br />

• Bird species identified as priorities in the Stirling Council Area LBAP (2002).<br />

12.2.9 Species which met one or more of the above criteria, and which were identified as being<br />

associated with the proposed wind farm site (e.g. via the desk study or field surveys), <strong>for</strong>med<br />

the group of target species <strong>for</strong> this assessment.<br />

Desk Study<br />

12.2.10 Ornithological data and details of protected areas <strong>for</strong> birds located within the development<br />

site and surrounding areas were sought from a range of sources including SNH, RSPB<br />

Scotland, Forestry Commission Scotland (FCS), and the Central Scotland Raptor Study<br />

Group. In<strong>for</strong>mation on designated sites within up to 20 km of the proposed development was<br />

sourced from SNH’s Sitelink website (http://www.snh.org.uk/snhi) and Stirling Council, and<br />

any site locations identified were mapped using ArcMap 10. The following conservation<br />

designations were considered in this search:<br />

• Special Protection Areas (SPAs);<br />

• Ramsar sites;<br />

• Sites of Special Scientific Interest (SSSIs);<br />

• National Nature Reserves (NNRs);<br />

• Local Council Nature Sites (LCNS); and<br />

• Sites of Importance <strong>for</strong> Nature Conservation (SINCs).<br />

Field Surveys<br />

12.2.11 A range of baseline field surveys were undertaken between September 2010 and May 2012<br />

to characterise the bird populations using the proposed application site and its surrounds, in<br />

terms of breeding and wintering populations and overall flight activity (see Table 12.2). The<br />

areas over which the different surveys were undertaken are shown in Figure 12.1. The<br />

following sections provide a summary of the methods used <strong>for</strong> each survey, whilst full details<br />

of methods, and timings of visits <strong>for</strong> each survey are provided in Appendix 12.1.<br />

Flight Activity Surveys<br />

12.2.12 Flight activity surveys were carried out in accordance with SNH guidelines (SNH 2005,<br />

revised 2010) and were designed to record the flight activity of birds using the airspace over<br />

the application site, and the spatial and temporal variation in that usage. Data from these<br />

surveys were used in the calculation of collision risk models (see Appendix 12.1 <strong>for</strong> full<br />

details).<br />

12.2.13 Vantage points (VPs) from which surveys were undertaken were selected so that the<br />

resultant viewsheds provided coverage of the air space from 20 m above ground level, and<br />

up to a radius of 2 km, of the area encompassed by all proposed turbine locations plus a<br />

surrounding buffer (of at least 200 m). This was initially carried out using GIS software in<br />

combination with Ordnance Survey (OS) digital terrain data, with viewsheds from selected<br />

VPs subsequently verified during site visits.<br />

12.2.14 Details of the three VP locations that were used to cover the finalised development area, and<br />

of the survey ef<strong>for</strong>t expended at each are provided in Appendix 12.1. Survey ef<strong>for</strong>t was in<br />

accordance with SNH guidance (SNH, 2005). The site boundary change in May 2011 meant<br />

that a small part of the revised turbine layout was not covered by the viewshed from the one<br />

existing VP location (i.e. VP1) that provided coverage of this revised layout (Figure 12.2).<br />

There<strong>for</strong>e, two additional VPs were selected to provide (virtually) full coverage of the<br />

proposed site boundary, with surveys from these two additional VPs undertaken from June to<br />

August in 2011 (Figure 12.2). Further surveys were also undertaken between late March and<br />

late May (inclusive) at all three VPs in 2012 to ensure that data <strong>for</strong> all parts of the revised<br />

turbine layout were available from this period of the year (Table 12.2).<br />

12.2.15 Overall, a total of 170 hours of VP surveys were undertaken between October 2010 and late<br />

May 2012. VP1 received a minimum of 6 hours survey per month (with minor exceptions),<br />

increasing to 9 hours during June and July when high levels of flight activity from breeding<br />

raptors might be expected. The two additional VPs each received between 6 – 12 hours<br />

survey in each of the three months over which they were surveyed in 2011, and all three VPs<br />

received 15 hours survey between late March and late May in 2012 (Table 12.A.2 in<br />

Appendix 12.1). Surveys were also planned to accurately record dawn, day and dusk<br />

activity.<br />

12.2.16 The surveys conducted from June to August in 2011 and from April to May in 2012 from all<br />

three VPs meant that almost the entire area of the proposed wind farm site boundary (and<br />

associated buffer) received coverage in all months of the breeding period at Carron Valley,<br />

with in excess of 36 hours per VP over this season, as recommended by SNH (2005).<br />

12.2.17 Minimum survey ef<strong>for</strong>t during the non-breeding season was also exceeded from VP1, with 42<br />

hours surveyed between October 2010 and March 2011 (and a further 3 hours in March<br />

2012). Although VPs 2 and 3 were not surveyed over these months, the data from VP1<br />

covered the vast majority of the site boundary and indicated that the winter period at Carron<br />

Valley is of very low importance to birds, particularly over <strong>for</strong>estry areas. The area of the<br />

Carron Valley reservoir that lies within the proposed site boundary and its 200m buffer was<br />

covered entirely from VP1. Thus, no significant flight activity <strong>for</strong> any species is likely to have<br />

been missed due to incomplete spatial coverage.<br />

12.2.18 During VP surveys, the observer scanned the airspace within the viewshed, recording all<br />

flying birds observed up to a distance of 2 km (or up to 3 km <strong>for</strong> geese and other large<br />

species). Flight-lines were mapped in the field (see Appendix 12.1) and those of target<br />

species were subsequently compiled in a GIS (ArcView v.10), with each flight-line linked to<br />

data on flight duration and flight height held in an MS Access database.<br />

12.2.19 The data collected on key target species flying over the proposed wind farm development<br />

site and the adjacent airspace were used to measure flight activity. For species with at least<br />

three separate flight events recorded at potential collision height (PCH), data were used in<br />

collision risk modelling (CRM) to estimate the number of individuals of each species predicted<br />

to collide with the turbine rotors. CRM was undertaken following the standard methods used<br />

<strong>for</strong> onshore wind farm sites, and as recommended by SNH (Band et al. 2007, see<br />

Appendix 12.1 <strong>for</strong> details of methodology).<br />

Breeding Raptor Surveys<br />

12.2.20 The proposed development site plus a 2 km buffer zone (Figure 12.1) was surveyed <strong>for</strong> all<br />

breeding raptor species in 2011. Target species were any Annex 1 (EU Birds Directive) and<br />

Schedule 1 (Wildlife and Countryside Act) listed species. Visits were carried out under a SNH<br />

Schedule 1 license (see Appendix 12.1 <strong>for</strong> details).<br />

12.2.21 Species-specific survey protocols followed the guidelines as set out by Hardey et al .(2009).<br />

Surveys were conducted in areas of suitable habitat within 2 km of the proposed<br />

development site in April and May 2011. Areas of suitable habitat included trees along the<br />

<strong>for</strong>est edge and older stands of trees within the <strong>for</strong>est, heather moor and other areas of open<br />

habitat, craggy rock faces and cliffs, and steep sided burns.<br />

12.2.22 Surveyors repeatedly stopped to scan <strong>for</strong> birds whilst undertaking walkover surveys, and the<br />

location of any nest sites, or nesting / territorial activity of raptors was recorded.<br />

Barn Owl Surveys<br />

12.2.23 Records of current barn owl nest box locations and previous usage were provided by FCS<br />

prior to surveys (Figure TA12.2.2 of Appendix 12.2 Ornithology Confidential Annex). In<br />

addition, potential barn owl nesting and roosting habitat (stone buildings, outhouses, mature<br />

trees with cavities) within the proposed development area and a surrounding 1km buffer were<br />

checked <strong>for</strong> occupancy on 13 April 2011, where access was possible.<br />

Black Grouse Surveys<br />

12.2.24 The proposed development site plus a 1.5 km buffer zone (Figure 12.1) was surveyed <strong>for</strong><br />

lekking (displaying) black grouse from April to mid-May 2011.<br />

12.2.25 The survey protocol followed the methodology outlined in Gilbert et al. (1998). Any known lek<br />

sites (in<strong>for</strong>mation provided by FCS and Central Scotland Black Grouse and Capercaillie<br />

Study Group) and areas of suitable lek habitat were identified prior to the first survey, and<br />

subsequently visited in early morning (and in dry, calm, conditions). The maximum number of<br />

males and females seen in the one hour be<strong>for</strong>e or the hour after dawn was recorded.<br />

Moorland Breeding Bird Surveys<br />

12.2.26 Surveys were undertaken on open moorland habitat within the proposed development area<br />

and a surrounding 500 m buffer. Only very small areas of such habitat were present within<br />

this area (Figure 12.1). Although the wind farm layout was altered subsequent to study area<br />

design, small sections of open moorland habitat were not covered by these surveys (e.g. to<br />

the north of Turbines 1 and 2). This is predicted to be insignificant in the evaluation of<br />

baseline data, particularly as sensitive breeding moorland species (e.g. waders) are unlikely<br />

to be located in close proximity to <strong>for</strong>est edges (e.g. Stroud et al. 1986).<br />

12.2.27 As recommended by SNH Guidance (SNH, 2005), three survey visits were undertaken<br />

between late April and late June. Survey methods followed those of Brown & Shepherd<br />

(1993), with the surveyor covering all parts of the open moorland ground to within 100 m on<br />

each survey visit. Bird locations and behaviour were plotted onto 1:10,000 scale OS maps<br />

using standard British Trust <strong>for</strong> Ornithology (BTO) notation, and an estimate of the numbers<br />

of breeding pairs of each species derived from the combined records from each visit.<br />

12.2.28 Further details of the survey timings and methods are provided in Appendix 12.1.<br />

Winter Walkover Surveys<br />

12.2.29 To assess bird occurrence and abundance on the site over the winter period, winter walkover<br />

surveys were completed monthly between September 2010 and March 2011. The walkover<br />

method combines the use of brief VP watches with a predetermined walked route designed to<br />

maximise coverage of the study site, and of the main terrestrial habitats present. The area<br />

covered includes the proposed turbine layout plus a 500 m buffer (WWO area in Figure 12.1).<br />

This made use of tracks, footpaths, accessible rides and open areas to aid efficiency in<br />

recording birds. The same route was used each month, although it was walked in alternate<br />

directions on the different surveys. Bird registrations were recorded on OS maps (see<br />

Appendix 12.1 <strong>for</strong> further details).<br />

12.2.30 Although the same survey area as the moorland breeding bird surveys was used <strong>for</strong> winter<br />

walkovers which meant incomplete survey coverage of the wind farm, coverage of the <strong>for</strong>est<br />

was deemed sufficient to be able to robustly determine species assemblage present,<br />

particularly when birds tend to be more mobile during the winter period.<br />

Point Count Surveys<br />

12.2.31 Cairnoch Hill is predominantly a sitka spruce Picea sitchensis and conifer species mix<br />

plantation, in varying stages of management. In order to survey a random sample of habitats,<br />

a grid of points (400 m apart) was generated using GIS software, and laid onto the turbine<br />

area plus a 500 m buffer. The original layout contained 109 points. After the layout change in<br />

May 2011, only the 19 points located within the revised layout (and associated buffer) were<br />

retained (Figure 12.3). Thus, the reporting of results is limited to data from those 19 sample<br />

points only. Three visits were made to each point during the breeding season, between April<br />

and July 2011.<br />

12.2.32 Counts took place within 5 hours of sunrise. The duration of each point count was five<br />

minutes, with a 2 minute settling period be<strong>for</strong>e each count. Birds heard or seen during a point<br />

count were recorded in one of three distance bands from the observer: 0-50 m, 50-100 m and<br />

> 100 m.<br />

12.2.33 Habitat within 100 m of each survey point was also recorded into one of five types: Open<br />

space/unplanted, Clearfell, Pre-thicket (incl. restock (3 m); and<br />

Other (windblow, tracks, deciduous trees).<br />

Assessment of the Significance of Effects<br />

12.2.34 Assessment of the significance of effects on ornithological interests follows the general<br />

Assessment Methodology in Chapter 2: The EIA and Scoping Process, and is also broadly<br />

based on the staged process outlined in the ecological impact assessment guidelines from<br />

the Institute of Ecology and Environmental Management (IEEM, 2006).<br />

12.2.35 The stages in the assessment are as follows:<br />

• determine the nature conservation value of the ornithological interests present within<br />

the study area;<br />

• identify the potential effects based on the nature of the proposed development;<br />

• determine the scale and magnitude of those effects;<br />

• determine the significance of those effects based on the magnitude and duration of the<br />

effects on the nature conservation value of the bird populations affected;<br />

• identify and assess mitigation measures required to address significant adverse<br />

effects; and<br />

• determine the significance of any residual effect once the benefits of the prescribed<br />

mitigation measures have been assessed.<br />

12.2.36 Evaluation of the ornithological resources identified by the baseline studies as ‘Valued<br />

Ornithological Receptors’ (VORs) has been guided by the IEEM (2006) guidelines. In<br />

accordance with these guidelines, the importance of each VOR has been assessed in<br />

relation to the conservation status of the species over the full range of geographical scales as<br />

listed below (Table 12.4). These correspond with the categories of importance defined in the<br />

significance matrix (Table 12.7).<br />

12.2.37 These criteria are intended as a guide and are not definitive. Attributing a value to a receptor<br />

is generally straight<strong>for</strong>ward in the case of designated sites, as the designations themselves<br />

are normally indicative of a value level. For example, a species designated within an SPA<br />

under the Habitats Directive is implicitly of European (i.e. International) importance.<br />

Professional judgement is there<strong>for</strong>e important when attributing a level of value to a particular<br />

species or individual habitat in non-designated areas. In these cases, reference has also<br />

been made to respective national and regional populations, and population trends.<br />

12.2.38 The Town and Country Planning (Environmental Impact Assessment) (Scotland) Regulations<br />

2011) (the EIA Regulations) require consideration of the types of effect in terms of how they<br />

arise, whether they are positive or negative, and their duration. The nature of each of these<br />

effects is defined in Table 12.5.<br />

12.2.39 The temporal scope of environmental effects is stated where known. Effects are typically<br />

described as:<br />

• Temporary – these are likely to be related to a particular activity and will cease when<br />

the activity finishes. The terms ‘short-term’ and ‘long-term’ may also be used to provide<br />

a further indication of how long the effect will be experienced; and<br />

• Permanent – this typically means an unrecoverable change.<br />

affected by a development. The elements used to define the scale of the effect of a<br />

development include determining:<br />

• the potential types of effect (as detailed in Table 12.5);<br />

• the scale/magnitude of the predicted effect (as detailed in Table 12.6); and<br />

• whether there are any cumulative effects that may affect the long-term integrity of the<br />

ecosystem(s) at the site.<br />

Criteria<br />

Only adverse effects are assigned this level of importance as they represent key<br />

factors in the decision-making process. These effects are generally, but not<br />

exclusively, associated with sites and features of international, national or<br />

regional importance that are likely to suffer a most damaging effect and loss of<br />

resource integrity. A major change at a regional or district scale site or feature<br />

may also enter this category.<br />

These beneficial or adverse effects are likely to be very important<br />

considerations at a local or district scale and, if adverse, are potential concerns<br />

to the scheme and may become material in the decision making process.<br />

These beneficial or adverse effects while important at a local scale are not likely<br />

to be key decision making issues. Nevertheless, the cumulative effect of such<br />

issues may influence decision making if they lead to an increase in the overall<br />

adverse effects on a particular area or on a particular resource.<br />

These beneficial or adverse effects may be raised as local factors but are<br />

unlikely to be of critical importance in the decision making process.<br />

Nevertheless they are of relevance in enhancing the subsequent design of the<br />

Scheme and consideration of mitigation or compensation measures.<br />

No effect or an effect which is beneath the level of perception, within normal<br />

bounds of variation or within the margin of <strong>for</strong>ecasting error. Such effects are<br />

not normally considered by the decision maker.<br />

12.2.43 The significance level generated from Table 12.7 was then assessed against the likelihood of<br />

such predictions occurring, and the confidence level of the effect on a population, based on<br />

expert judgement and evidence from the existing literature. A scale of confidence, as<br />

recommended by IPCC (2005) can then be used:<br />

• Virtually certain: >99% probability of occurrence;<br />

• Very likely: >90% probability;<br />

• Likely: >66% probability;<br />

• About as likely as not: 33-66% probability;<br />

• Unlikely:

the impact assessment will however be at the wider spatial levels (i.e. regional, national or<br />

international), which corresponds with SNH policy (2006) which states that: “SNH will not<br />

normally object to a windfarm proposal on account of purely local impacts, if the impacts are<br />

not avoidable by reasonable means, if they do not result in any wider impact on the regional<br />

population, and provided the impacts do not affect populations protected within a designated<br />

site”. These conditions highlighted by SNH have been considered in the impact assessment<br />

process so that no potentially significant effects are omitted.<br />

12.3 Baseline In<strong>for</strong>mation<br />

Sources of Data<br />

12.3.1 The predicted effect of the proposed wind farm on VORs was assessed based on in<strong>for</strong>mation<br />

in the published scientific literature, ‘grey’ literature (not subject to peer review) and expert<br />

judgement.<br />

12.3.2 Estimations of the possible extent and duration of effects are based on studies and key<br />

review papers in the scientific literature on ornithology and wind farms (e.g. Langston and<br />

Pullan, 2003; Drewitt and Langston, 2006). Disturbance and displacement distance ranges<br />

used in this assessment have been based on published papers including Ruddock and<br />

Whitfield (2007) and Pearce-Higgins et al. (2009). Estimations of regional populations have<br />

been gathered and interpreted from most recent published reports such as Scottish Raptor<br />

Monitoring Scheme annual reports (e.g. Etheridge et al. 2011) and Forrester et al. (2007).<br />

Planning Policy Review<br />

12.3.3 The planning policy overview <strong>for</strong> this proposed development is presented in Chapter 5:<br />

Planning Policy Overview, which includes the identification of the Development Plan policies<br />

and material considerations relevant to the determination <strong>for</strong> the proposed Carron Valley<br />

Wind Farm.<br />

12.3.4 In terms of Development Plan policies with direct relevance to ornithological interests within<br />

the proposed development area, policy ENV1 of the CSSP aims to prevent developments<br />

that have adverse effects on wildlife habitats and other natural features, and states that all<br />

development proposals will be considered within the context of the Local Biodiversity Action<br />

Plans.<br />

12.3.5 In addition to this, Policy POL.E54 and Policy POL.E55 of the SCLP set out the hierarchical<br />

approach taken to special area designations that contribute to nature conservation in relation<br />

to developments.<br />

12.3.6 Thus, as defined by POL.E54, The Council will not normally permit or approve developments<br />

or land-use changes which may adversely affect wildlife interests and conservation<br />

management of Local Nature Reserves, non-statutory and community nature reserves and<br />

fully defined Wildlife Sites, or the integrity or continuity of the landscape features listed below,<br />

which are of major importance <strong>for</strong> wild fauna and flora. In cases where the reasons in favour<br />

of a development clearly outweigh the desirability of retaining the feature(s), mitigating<br />

measures, including replacement habitat creation will be sought on land within the<br />

developers’ control.<br />

12.3.7 POL.E55 addresses the remainder of the hierarchy set out in the SCLP. It advises that; (i) a<br />

new development will not be acceptable where it is likely to have a significant adverse effect<br />

on the integrity of a Special Protection Area, Special Area of Conservation, or Ramsar site<br />

(with the few possible extenuating circumstances described in SOEnD Circular 6/1995); and<br />

(ii) a development will not normally be acceptable which is likely to affect an SSSI or NNR,<br />

unless it can be demonstrated that it will not have a significant effect on the special interest of<br />

the site.<br />

12.3.8 Other material considerations relevant to ornithological interests include PAN 60 – Planning<br />

<strong>for</strong> the Natural Heritage. Although this does not specifically address wind farm developments,<br />

it provides general guidance on the siting and design of development in relation to Scotland’s<br />

natural environment. The general principle, as stated in paragraph 52, is that ‘while<br />

inappropriate development can detract from scenic quality or adversely affect particular<br />

habitats, species or earth heritage interests, well designed and carefully sited development<br />

can complement the landscape and substantially increase natural heritage interest’.<br />

Designated Sites<br />

12.3.10 A desk-based study was carried out to obtain in<strong>for</strong>mation on all statutory and non-statutory<br />

designated sites with ornithological interests within 20 km (SPAs and Ramsar sites), 10 km<br />

(SSSIs, LNRs and other national-level designations) and 5 km (LCNSs) (Table 12.10). The<br />

maximum 20 km search area was based on regular <strong>for</strong>aging ranges of osprey and geese,<br />

and based on SPA connectivity guidance from SNH (2012a).<br />

12.3.11 There are no statutory sites within the application site boundary, nor within 13km of the site.<br />

12.3.12 Two SPAs are located within 20 km – the Firth of Forth SPA and Ramsar site, which hosts a<br />

wide variety of waterfowl during the winter period; and Slamannan Plateau SPA which at the<br />

time of citation held over 53% of the Great British population of Taiga bean goose. No SSSIs<br />

or other national-level sites with an ornithological interest are located within 10 km of the site.<br />

12.3.13 Only one LNR, Dumbreck Marsh, is within 10 km of Carron Valley, and although no specific<br />

in<strong>for</strong>mation is available it is likely to contain a lowland grassland/marshland assemblage of<br />

birds.<br />

12.3.14 Four LCNSs with noted ornithological interest can be found within 5 km of the site: Carron<br />

Valley, Loch Coulter and North Third Reservoirs, and Gargunnock Hills. The first three of<br />

these sites consist primarily of freshwater and wetland habitats with associated wildlife, with<br />

the Gargunnock Hills LCNS comprising mainly moorland habitat with an assemblage<br />

influenced by red grouse management.<br />

Field Survey Results<br />

Flight Activity Surveys<br />

12.3.15 A total of 19 species was recorded during the flight activity surveys undertaken at VPs 1-3<br />

between October 2010 and May 2012 (Table 12.11, Figures 12.4 to 12.7). In general, flight<br />

activity during the breeding season within the application site and surrounding area was<br />

relatively low compared to winter usage, with the exception of osprey that is only present<br />

through the summer months. During summer a small number of raptor and wader flights<br />

were recorded.<br />

12.3.16 In winter months the area is used more frequently, particularly by wintering ducks on the<br />

Carron Valley Reservoir, and overflying wildfowl. Although there was regular flight activity<br />

recorded, the vast majority was well away from the proposed turbine area, and only two<br />

species (osprey and greylag goose) had sufficient flight events at PCH within the proposed<br />

turbine area to justify undertaking CRM. For all other species there were either zero, or<br />

insufficient ‘at-risk’ flights – i.e. recorded at PCH within the proposed wind farm development<br />

area.<br />

Breeding Raptors<br />

12.3.17 Consultation with local FCS staff, and on-site surveys in 2011 resulted in identification of two<br />

Annex I / Schedule 1 raptors breeding within the application site boundary and 2 km survey<br />

buffer in recent years: osprey and hen harrier. The locations of breeding activity are detailed<br />

in Appendix 12.2 (confidential) and Figures TA12.2.1 and TA12.2.2 therein.<br />

12.3.18 In 2009, two artificial osprey nest plat<strong>for</strong>ms were built by FCS in <strong>for</strong>estry to the south of<br />

Carron Valley Reservoir, within 2 km of the application site. Neither plat<strong>for</strong>m has been used<br />

by breeding osprey to date. In 2010 there was evidence of an unconfirmed osprey nest<br />

within the application site boundary (Figure TA12.2.1 of Appendix 12.2 (confidential)). There<br />

was also evidence that a natural osprey nest was newly-built within <strong>for</strong>estry to the south of<br />

the reservoir, approximately 1.6 km from the application site boundary. Observations<br />

suggested that this pair laid, but the brood was later abandoned.<br />

12.3.19 Raptor surveys in 2011 highlighted a potentially new osprey nest site within the application<br />

site boundary (Figure TA12.2.1 of Appendix 12.2 (confidential)). Adults were seen regularly<br />

carrying food into an area of mature spruce. A survey of this woodland failed to find a nest,<br />

but because this survey occurred after the unseasonably strong winds in late May, it is likely<br />

that this nest was destroyed prior to the survey.<br />

12.3.20 The confirmed 2010 osprey nest to the south of the reservoir again failed to breed<br />

successfully in 2011.<br />

12.3.21 It is considered possible that breeding evidence around Carron Valley Reservoir may have<br />

been either from one pair, or two separate pairs. In the case of the <strong>for</strong>mer, ospreys often<br />

build "frustration" nests if their first nest fails, although they rarely lay eggs a second time.<br />

This may have been the case in 2010 and 2011 although there was not enough evidence to<br />

confirm this.<br />

12.3.22 There was evidence from FCS that a hen harrier pair attempted to breed within the northern<br />

part of the application site boundary in 2009 (Figure TA12.2.2 of Appendix 12.2<br />

(confidential)), although no breeding evidence has been recorded in subsequent years, likely<br />

due to maturation of <strong>for</strong>estry which will have caused the habitat to become unsuitable <strong>for</strong> the<br />

species. The nest site was approximately 700 m from the closest turbine location. Only one<br />

flight was recorded during flight activity surveys (in September, Table 12.11), suggesting that<br />

the species does not currently breed in the wider area.<br />

12.3.23 FCS has recorded sightings of goshawk over the main <strong>for</strong>est block, and although breeding is<br />

possible, no evidence has been recorded to date by any conservation organisation or during<br />

baseline surveys. It was considered from flight activity surveys in 2010/11 that sightings were<br />

of a lone male.<br />

12.3.24 Although there was no breeding evidence recorded, flight activity surveys have shown that<br />

merlin use the <strong>for</strong>estry within the application site boundary in summer months, suggesting<br />

that there may be occupation of a territory either within or near the site. However, as flights<br />

were recorded in March, late July and early August only, it is more likely that the site is used<br />

prior to and after birds have attempted to breed elsewhere.<br />

12.3.25 No peregrine flights were recorded during flight activity surveys from the three VPs covering<br />

the proposed site boundary (and associated buffer) and used to generate data <strong>for</strong> CRM<br />

calculations. However, a single peregrine flight was recorded on the south western edge of<br />

the flight activity survey buffer in October 2010. This was recorded from an additional VP<br />

location (subsequently disused following the site boundary change in May 2011). This single<br />

flight was not at PCH, and overall the data suggest the application site is not part of any<br />

territory.<br />

12.3.26 Incidental records during various surveys in 2010/11 recorded regular buzzard activity, with<br />

the suggestion that the area <strong>for</strong>ms part of at least one breeding territory. It is also likely that<br />

the site hosts at least two tawny owl territories.<br />

Barn Owl<br />

12.3.27 FCS provided records of barn owl nest boxes and other activity in 2010. There are two barn<br />

owl boxes placed at the <strong>for</strong>est edges along the application site boundary, one within 1 km,<br />

and a further two are known within <strong>for</strong>estry to the south of the Carron Valley Reservoir<br />

(beyond 1 km of the application site, Figure TA12.2.2, Appendix 12.2 (confidential)).<br />

Carron Valley Wind Farm<br />

12.3.28 In 2010, one of the nests within the application site recorded breeding activity, although the<br />

nest was predated by pine marten Martes martes. The other two boxes north of the reservoir<br />

were not used that year. Of the two boxes to the south, one again was used but predated by<br />

pine marten, and a second was used as a roost.<br />

12.3.29 There was no evidence of barn owl nesting or roosting elsewhere within a 1 km buffer, as<br />

determined from a survey conducted in April 2011.<br />

Black Grouse<br />

12.3.30 Locations of historic lek sites within the past decade or so were provided by FCS and Central<br />

Scotland Black Grouse and Capercaillie Study Group. There were two sites within the<br />

application site boundary, although dates and maximum sizes of these leks were unknown.<br />

A further lek site was within 1.5 km of the site boundary, and five lek sites were located<br />

outside this buffer within <strong>for</strong>estry areas to the south of Carron Valley Reservoir.<br />

12.3.31 All of these lek sites were checked in 2011, but no birds were found at them, or within the<br />

entire 1.5 km buffer surrounding the indicative turbine layout. It is likely that these leks no<br />

longer exist in these locations, and the maturation of plantation will have rendered habitats<br />

considerably less suitable (Pearce-Higgins et al. 2007). The only black grouse record within<br />

the application site was of a flushed grey hen in March 2011, during a winter walkover<br />

survey. An incidental record of a flushed black cock was provided from a surveyor en route<br />

to a flight activity survey, some 4 km south of the application site boundary, in November<br />

2010, and one black cock and two grey hens were recorded in the same area during a winter<br />

walkover survey in January 2011.<br />

12.3.32 A series of droppings attributed to black grouse were recorded along the southern edge of<br />

plantation to the south of the Carron Valley Reservoir in late March 2011. This area was<br />

approximately 2.8 km from the application site boundary.<br />

Moorland Breeding Birds<br />

12.3.33 As the application site comprises mainly plantation <strong>for</strong>estry, only a small area of open<br />

moorland required study within the 500 m buffer (Figure 12.1). Consequently only two<br />

species of conservation concern were recorded during the three survey visits (curlew and<br />

skylark). Table 12.12 presents records of these species during each survey. It is considered<br />

that up to two curlew pairs and seven skylark pairs occurred within this survey area.<br />

12.3.34 The winter walkover surveys recorded a typical suite of woodland passerines. In total, 44<br />

species were recorded within the application site boundary and 500 m buffer (Appendix 12.1).<br />

Of these, 21 species were of conservation concern, including four Schedule 1 species<br />

(goshawk, crossbill, brambling and redwing, although it is very likely that the latter two at<br />

species recorded flying over the site only (Appendix 12.1). Few species of conservation<br />

value were recorded breeding, with four Red-listed species (cuckoo, song thrush,<br />

grasshopper warbler and skylark) most noteworthy (Table 12.14). One Annex I species<br />

(osprey) was recorded in flight only.<br />

Collision Risk Modelling<br />

12.3.36 CRM followed the method presented by Band et al. (2007), recommended by SNH. This<br />

involves a three-step process, by first using flight activity survey results as a sample, to<br />

estimate the number of flights likely to take place at rotor height during a period of time<br />

(usually either a year or a breeding season), then calculating what proportion of these will<br />

take place within the total rotor swept area of the wind farm, assuming no avoidance actions<br />

(i.e. placing a bird at risk of collision). The next step is then to calculate the probability that if<br />

a flight does pass within the rotor swept area of a turbine, then that bird will be struck by a<br />

rotating blade. This probability is multiplied by the number of at-risk flights estimated in stage<br />

1. The final stage is then to account <strong>for</strong> the birds’ likely ability to avoid colliding with turbines<br />

in the vast majority of occasions, by behavioural actions either close to individual rotors, or by<br />

avoiding the wind farm as a whole. This avoidance rate (typically at least 98%, and 99% <strong>for</strong><br />

geese – SNH 2010) is then multiplied by the figure calculated at stage 2 to give an overall<br />

estimate of mortality rate.<br />

12.3.37 For each target species recorded in sufficient numbers, an annual collision rate was predicted<br />

using either a directional or non-directional (random) version of the model. The choice of<br />

model <strong>for</strong> each target species was based on its pattern of flight behaviour within the study<br />

area. The directional model is appropriate when a species tends to move across the wind<br />

farm area in a particular direction. This type of flight behaviour is characteristic of species on<br />

migration or making regular movements between feeding and roosting sites and SNH<br />

advocates using it <strong>for</strong> groups such as geese, swans, divers and ducks. A non-directional<br />

model is more appropriate where the flights of a particular species are not predominantly in<br />

any direction. This is usually the case <strong>for</strong> birds moving around within a breeding or hunting<br />

territory that is wholly or partly within the site of interest. This approach, which assumes that<br />

the direction of flights is random, is usually appropriate <strong>for</strong> breeding and non-breeding raptors<br />

and waders.<br />

12.3.38 The Risk Zone within which birds were considered to be at risk of collision was taken to be<br />

the area enclosed by the tips of the outermost turbine rotors, plus a 200 m buffer to allow <strong>for</strong><br />

a degree of surveyor error when mapping flightlines, which is considered to be in line with<br />

SNH (2005) guidance.<br />

12.3.39 A summary of the output from the CRM is presented in Table 12.15 below, with full details<br />

given in Appendix 12.1, together with all VP flight survey data.<br />

12.3.40 Following a review of constraints in May 2011, and subsequent review in March 2012, layout<br />

changes resulted in the assessment of ornithological effects being carried out <strong>for</strong> a slightly<br />

different study area compared to those originally surveyed (Figure 12.1).<br />

12.3.41 As described above, this difference was rectified <strong>for</strong> the flight activity surveys by the addition<br />

of two new VPs (2 and 3, Figure 12.2), which provided coverage of the relatively small part of<br />

the revised site boundary not covered by VP1. As a result of the VP coverage in 2010-11<br />

being incomplete during the early breeding season across the northern part of the site, further<br />

surveys from all three VPs were conducted from late March to May 2012 to increase the<br />

confidence of the impact assessment and gather more flight activity data <strong>for</strong> each species <strong>for</strong><br />

inclusion in CRM. It is not considered that this will prove to be a significant constraint to<br />

providing a robust assessment of ornithological effects.<br />

12.3.42 The survey areas <strong>for</strong> breeding birds and winter walkovers were also slightly different<br />

compared to the required study areas. The small areas not directly covered are however<br />

very unlikely to host any additional target species, particularly with the availability of data from<br />

a variety of sources including nearby wind farm projects with overlapping survey areas, and<br />

FCS data, and so there is unlikely to be a material difference in the accuracy of assessment.<br />

Receptor Sensitivity<br />

12.3.43 A total of 28 species met at least one of the criteria identified in paragraph 12.2.8 and<br />

there<strong>for</strong>e constitute the preliminary VORs of the development site. A summary of their<br />

presence, conservation status and value, and legislative protection is given in Table 12.16.<br />

12.3.44 The aim of the evaluation of ornithological effects was to report on “likely” significant effects,<br />

based on the EIA Regulations guidance, rather than every perceivable effect. As such, a<br />

number of species were discounted from assessment as baseline survey results indicated<br />

that significant effects were not likely to occur at a regional scale or above (<strong>for</strong> example if no<br />

breeding was recorded and site usage was rare). Consequently such effects do not require<br />

assessment under the terms of the EIA Regulations and SNH (2006) guidelines.<br />

12.3.45 Species that were scoped in or out of the assessment are shown in Table 12.16. Although a<br />

number of the species that have been scoped out are priority species within the UKBAP,<br />

LBAP and/or are Red or Amber-listed species of BoCC (Eaton et al. 2009), and would<br />

there<strong>for</strong>e generally be considered of Regional conservation value (Table 12.4), their<br />

conservation status reflects a decline in numbers rather than rarity or a concentration of<br />

population in a few sites; they remain relatively common and widespread in the UK. Even<br />

though these species (e.g. song thrush, dunnock) were identified as breeding or at least<br />

being present within the study area, they occurred in very low numbers (absolutely and/or<br />

relative to national and regional populations) in an area of limited habitat suitability.<br />

12.3.46 SNH (2006) states that “the inclusion of a species within an LBAP should not lead to SNH<br />

objecting to a proposal because of local impacts on that species, unless in SNH’s judgement<br />

the status of the species regionally or nationally could be compromised by the development”.<br />

This can be reasonably expanded to include UKBAP or Red-listed species that are included<br />

in their respective classification based on a relative decline in numbers from a high baseline<br />

rather than an inherent rareness at a national level. They are there<strong>for</strong>e omitted from the<br />

impact assessment.<br />

12.3.47 Other species such as redwing and brambling are Red-listed on the basis of their breeding<br />

populations, because the UK is at the edge of their breeding range and has, at best, very<br />

small breeding numbers. No breeding evidence was recorded <strong>for</strong> such species in the study<br />

area, and there<strong>for</strong>e these species were omitted from further consideration. Other species<br />

(mainly waterfowl on Carron Valley Reservoir) have been recorded flying in low numbers<br />

within the proposed turbine area, and do not use the application site <strong>for</strong> breeding, feeding or<br />

roosting. These species were also omitted from assessment.<br />

12.3.48 When considering all omitted species of conservation value, it was concluded that based on<br />

population estimates in Forrester et al. (2007) and other sources, none were found in<br />

regionally-important numbers within the study area, and are at most of a District conservation<br />

value.<br />

12.3.49 Table 12.16 there<strong>for</strong>e shows that three species will be considered individually, with the<br />

remainder of breeding species not being of regional or greater significance alone, but are<br />

considered as part of the overall breeding bird assemblage within the application site<br />

boundary. The following VORs were there<strong>for</strong>e subject to impact assessment, and<br />

Designated Sites<br />

12.3.50 The statutory and non-statutory designated sites in proximity to Carron Valley, as outlined in<br />

Table 12.10 are also considered in the preliminary list of VORs. It can however be<br />

reasonably concluded that none will be adversely affected by the proposed wind farm<br />

development <strong>for</strong> the following reasons.<br />

12.3.51 Of the two SPAs, no Taiga bean geese were recorded during baseline surveys, and so any<br />

connectivity with the Slamannan Plateau SPA is considered very unlikely. Although some<br />

waterfowl species that are designated within the Firth of Forth SPA citation were found over<br />

winter at Carron Valley, it is very unlikely that these individuals would utilise the SPA (15 km<br />

distant at its closest point) at any time, except perhaps briefly on passage. With very little<br />

activity within the application site itself, connectivity with the SPA is likely to be negligible.<br />

12.3.52 Regarding the locally-designated non-statutory sites (LNR and LCNS), no particular species<br />

have been highlighted as residing within the sites at any time. The general bird assemblages<br />

found within these sites are likely to remain local to the area, and with the exception of the<br />

adjacent Carron Valley Reservoir LCNS, likely to be beyond <strong>for</strong>aging range. For the latter<br />

site, it has already been established that the effects of the wind farm on waterfowl are likely to<br />

be minimal, with habitat within the application site boundary unsuitable <strong>for</strong> such species.<br />

12.3.53 It is there<strong>for</strong>e concluded that no designated sites require consideration in the assessment<br />

stage, and are there<strong>for</strong>e scoped out.<br />

Reference Populations and Conservation Status<br />

12.3.54 As described in the Assessment of the Significance of Effects section, the significance of a<br />

potential effect on each VOR was determined by considering the magnitude, extent and<br />

duration of the effect in relation to the conservation importance (sensitivity) of the VOR within<br />

the context of the reference population.<br />

12.3.55 According to SNH (2006), an effect is judged as of concern where it would “adversely affect<br />

the favourable conservation status of a species, or stop a recovering species reaching<br />

favourable conservation status, at international or national level, or regionally”. This is likely<br />

to be the case where a substantial or moderate adverse effect, not likely to be tolerable, is<br />

predicted using the matrix procedure, although expert judgement is applied in all cases.<br />

12.3.56 The term ‘favourable conservation status’ (as articulated within the Habitats Directive) is<br />

defined by SNH (2006) as “the sum of influences acting on it which may affect its long-term<br />

distribution and abundance, within the geographical area of interest (which <strong>for</strong> the purposes<br />

of the Directive is the EU)”. This interpretation has become increasingly common in court<br />

cases within the context of the Birds Directive. Conservation status is favourable where:<br />

• population dynamics indicate that the species is maintaining its population size on a<br />

long-term basis as a viable component of its habitats;<br />

• the natural range of the species is not being reduced, nor is likely to be reduced <strong>for</strong> the<br />

<strong>for</strong>eseeable future; and<br />

• there is (and will probably continue to be) a sufficiently large habitat to maintain its<br />

populations on a long-term basis.<br />

12.3.57 The conservation status of each VOR is there<strong>for</strong>e considered at the international, national<br />

and/or regional scale, depending on whether the population is breeding, migratory or<br />

overwintering. For non-breeding or migratory species, consideration at a national scale is<br />

more appropriate than at regional level or lower.<br />

12.3.58 For breeding birds, the regional scale equates to SNH’s Natural Heritage Zones (NHZ),<br />

where there is high biogeographical coherence within each zone. In this case, the proposed<br />

wind farm development site lies within the West Central Belt (NHZ 17) but is also within<br />

10 km of the Eastern Lowlands (NHZ 16) (Figure 12.8). It is considered that the West Central<br />

Belt NHZ more closely reflects the upland moorland and plantation habitat within and around<br />

the development site, and so is used as the primary reference population. Other populations<br />

(e.g. Scottish Raptor Study Group survey areas) will however be considered where<br />

appropriate.<br />

12.3.59 In order to determine whether the conservation status of a species’ population will be<br />

adversely affected, it is necessary to obtain the best data on each VOR’s current population<br />

and recent trends. These are presented below.<br />

Osprey<br />

12.3.60 Osprey is listed in Annex I of the EU Birds Directive, and Schedule 1 to the Wildlife and<br />

Countryside Act, and is a rare breeder in the UK.<br />

12.3.61 The species has shown a steady long-term increase in breeding numbers since its mid-20 th<br />

century reintroduction, with a minimum of 208-211 pairs recorded in Scotland in 2008, which<br />

is an increase in the 140 pairs present at 198 nest sites checked in Scotland in 2007<br />

(Etheridge et al. 2010, 2011). The national population is likely to there<strong>for</strong>e be around 215<br />

pairs, based on the most recent UK breeding report (Holling et al. 2011).<br />

12.3.62 From the latest Scottish Raptor Study Monitoring Report (2008 – Etheridge et al. 2011) there<br />

were 21 monitored pairs in the Central Scotland study area, which was an increase from 18<br />

in the previous year (Etheridge et al. 2010), and up from 12 pairs in 2004 (Etheridge et al.<br />

2007, Diagram 1). Of these 21 pairs, 16 fledged a total of 34 young, with the other five laying<br />

eggs but subsequently failing (giving a mean brood size of 1.6 fledged young per monitored<br />

occupied nest site). In 2007 there were 18 pairs found, of which 13 were successful, rearing<br />

32 young (1.8 fledged young per monitored occupied nest site). These are higher success<br />

rates than the Scottish average of 1.5 young per monitored occupied nest site in 2008, and<br />

1.3 in 2007.<br />

12.3.63 According to Etheridge et al. (2011), the increasing number of pairs in southern Scotland is<br />

largely due to the provision of nesting plat<strong>for</strong>ms by a few enthusiasts, but it also reflects<br />

range expansion of this species in Scotland. In general, from results in Diagram 1, it appears<br />

that productivity is relatively high in Central Scotland compared to the Scottish average,<br />

which will further encourage growth and expansion of the population.<br />

12.3.64 Ospreys are slowly colonising south and central Scotland and the regional population<br />

appears to be increasing. There<strong>for</strong>e, based on the above in<strong>for</strong>mation, osprey is a VOR of<br />

Greylag Goose<br />

12.3.65 Greylag goose is an Amber-listed species, but is internationally-important within the UK as at<br />

least 20% of the non-breeding population is found here. Of these, at least 50% are found in<br />

10 or fewer sites (Eaton et al. 2009).<br />

12.3.66 Although some local feral birds may have been present during surveys, with the large<br />

majority of greylag goose flight activity recorded during autumn and winter migration periods,<br />

the birds present over Carron Valley are likely to be part of the Icelandic-breeding population<br />

which winters in the UK. The most recent census data available from 2010 indicated that the<br />

British population reached 110,962 individuals (Mitchell, 2011). Compared to population<br />

estimates in 2009, the 2010 figures represent a very small increase of 1.3% in the greylag<br />

goose population, although the long-term trend is one of continued growth. The<br />

Stirling/Falkirk/Clackmannan areas held relatively low peak numbers of 630 birds in October.<br />

12.3.67 Although there has been a redistribution of greylag goose across the UK in recent years, with<br />

more northerly areas now favoured, numbers remain high, indicating that as a migratory<br />

species of international conservation value, it has a favourable conservation status at a<br />

national level. Although a widespread migratory species, the peak flock size of 103<br />

individuals over the application site may be of at least regional conservation value (medium<br />

importance).<br />

Barn Owl<br />

12.3.68 Barn owl is listed in Schedule 1 of the Wildlife and Countryside Act, is an Amber-listed BoCC,<br />

and is a priority species of in the UKBAP and Stirling Council LBAP.<br />

12.3.69 The barn owl has a cosmopolitan world distribution and is not threatened over most of its<br />

range. The British and Scottish breeding populations remain strong in many areas, but the<br />

species is Amber-listed due to a moderate range decline (25-49%) in the UK over the last 25<br />

years (Eaton et al. 2009). The Scottish breeding population has been estimated as 500-1,000<br />

Carron Valley Wind Farm<br />

pairs and 1,000-2,000 individuals (winter) (Forrester et al. 2007), with a UK breeding<br />

population of 4,000 pairs (Robinson, 2005).<br />

12.3.70 Distributional data provide evidence <strong>for</strong> a decline throughout the 20 th century, although<br />

annual monitoring started only very recently. The erection of barn owl nest boxes, already<br />

numbering 25,000 by the mid 1990s, has enabled the species to occupy areas that were<br />

previously devoid of nesting sites, and may have been a factor in improving nesting success.<br />

Breeding bird survey data <strong>for</strong> the UK show a large increase since 1995, with the strong<br />

caveat that the previous surveys monitored nocturnal species poorly (Risely et al. 2010). This<br />

trend suggests however that the current population estimate is much too low (BTO BirdFacts,<br />

as per Robinson 2005).<br />

12.3.71 The Scottish Raptor Study Group monitored 369 pairs across Scotland in 2008, and just 276<br />

(75%) pairs succeeded in rearing any young (Etheridge et al. 2011). The mean brood size<br />

was 1.9 young per monitored pair, which is low compared to an 86% success rate and a<br />

mean brood size of 2.8 young in 2007. The low success rate in 2008 was attributed to a<br />

crash in vole numbers in late spring (voles being a major food source <strong>for</strong> the species).<br />

12.3.72 A total of 64 pairs were monitored in the Stirling area by the Raptor Study Group in 2008, of<br />

which 44 pairs successfully fledged a total of 72 young (1.1 young per pair or a mean brood<br />

size of 1.6) which was low compared to the Scottish average. This population represents<br />

only a sample of the likely total regional population. Using an estimated Scottish population<br />

of 500-1,000 pairs (Forrester et al. 2007), the Scottish Raptor Study Group monitored 41-<br />

81% of these (409 pairs) in 2008. If applying this monitoring rate at a regional level, the NHZ<br />

population is estimated to be around 79-155 pairs.<br />

12.3.73 Although trends are difficult to discern due to incomplete survey coverage, as a result of an<br />

apparent long-term decline (albeit with some signs of improvement) barn owl is a VOR of<br />

National conservation value (Schedule 1 listed), and has an unfavourable conservation status<br />

at a national and regional (NHZ) level. The one pair of barn owl recorded within the<br />

application site boundary may there<strong>for</strong>e be up to a regional conservation value (medium<br />

importance).<br />

Breeding Bird Assemblage<br />

12.3.74 Although the species’ populations recorded during breeding bird surveys within and adjacent<br />

to the application site are likely to be of at most District level conservation value alone, the<br />

assemblage as a whole may be seen to reach regional conservation value (medium<br />

importance), due to relatively uncommon and/or declining species such as crossbill, curlew<br />

and cuckoo in the context of central Scotland.<br />

12.4 Topic Specific Design Evolution<br />

12.4.1 Although not a determining factor, the decision to locate turbines only on the northern <strong>for</strong>est<br />

block at Carron Valley was taken in cognisance of the potential effects on VOR species<br />

across the <strong>for</strong>estry plantation as a whole, and the retention of <strong>for</strong>estry to the south of the<br />

reservoir offered the opportunity to propose artificial nest plat<strong>for</strong>ms <strong>for</strong> ospreys and other<br />

mitigation to offset some of the effects on bird species.<br />

12.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

12.5.1 This section presents an evaluation of changes predicted during construction, operational<br />

and decommissioning activities against the criteria outlined in the Assessment of the<br />

Significance of Effects section above. The nature of the potential effects of the development<br />

are considered in turn <strong>for</strong> each VOR.<br />

Establishing the Baseline Situation<br />

12.5.2 As recommended by IEEM (2006), consideration must be given to what the baseline situation<br />

will be at the time of project construction, as it may not be the same as the conditions at the<br />

time of the impact assessment. In order to determine this, it is necessary to try to predict any<br />

changes that will alter conditions prior to the start of the proposed construction.<br />

12.5.3 As the application site lies within an area of commercial <strong>for</strong>estry, a phased felling strategy by<br />

FCS is in place until at least 2045, and there<strong>for</strong>e will likely cover the whole lifespan of the<br />

wind farm. Phase 1 felling (2010-2014) will occur be<strong>for</strong>e commencement of construction<br />

activities in 2015, and this comprises the harvesting of 33.52 ha of mature trees (Figure<br />

TA4.3.1 of Appendix 4.3). These areas will then be restocked with a combination of sitka<br />

spruce, lodgepole pine, larch, Scots pine and some broadleaved trees.<br />

12.5.4 As a result there will be a loss of current nesting habitat <strong>for</strong> some species due to clearance of<br />

<strong>for</strong>estry in Phase 1 blocks. Conversely, the new habitat (open grassland, scrub, young<br />

plantation, <strong>for</strong>est edges) may provide feeding and nesting opportunities <strong>for</strong> the same, or<br />

different species. This provides a material difference in baseline condition to that surveyed.<br />

12.5.5 Subsequent felling phases may coincide with the construction and operational activities of the<br />

wind farm, resulting in potential cumulative disturbance or displacement events.<br />

12.5.6 The most realistic baseline situation will there<strong>for</strong>e be similar in nature to at present with<br />

<strong>for</strong>estry being cleared and replaced on a rotational basis, albeit different areas within the<br />

application site will be affected at particular times.<br />

Construction<br />

Habitat Loss<br />

12.5.7 Direct habitat loss through wind farm construction may result in loss or fragmentation of<br />

nesting or <strong>for</strong>aging habitat <strong>for</strong> particular species. In the context of wind farms, this is<br />

generally considered to be of low magnitude, as construction usually only involves small<br />

losses of land associated with turbine bases, access tracks and other infrastructure<br />

compared to overall <strong>for</strong>aging extent of many key species (Drewitt and Langston 2006). An<br />

exception to this may be <strong>for</strong> example, where the felling of a tree would result in the loss of a<br />

traditional raptor nest.<br />

12.5.8 With respect to birds, in most cases physical land take is likely to be considerably less than<br />

any effective habitat loss due to displacement from the wind farm area. Effects may be more<br />

widespread if developments interfere with hydrological patterns of wetland or peatland sites<br />

(Drewitt and Langston 2006).<br />

12.5.9 Habitat at Carron Valley is generally not considered of high value <strong>for</strong> birds at a regional or<br />

larger scale. The predominant Phase 1 habitat is conifer plantation which is of low<br />

conservation value <strong>for</strong> most VORs, either <strong>for</strong> breeding or <strong>for</strong>aging.<br />

Osprey<br />

12.5.10 The 2010 and 2011 unconfirmed osprey nest sites within the application site boundary are<br />

both within 100 m of proposed turbine locations. It is also evident however that neither of<br />

these nest sites will be available at the time of wind farm construction as both are within<br />

Phase 1 felling blocks and will be removed by FCS (outside of the breeding season) prior to<br />

the construction phase. Notwithstanding this, evidence suggests that the 2011 nest site has<br />

already been destroyed in May 2011 due to high winds.<br />

12.5.11 There have been two artificial nests set up within <strong>for</strong>estry to the south of Carron Valley<br />

Reservoir in recent years, and although there is no evidence to date that these have been<br />

used, they should be seen as potential alternative nesting habitat. One of these plat<strong>for</strong>ms is<br />

within 500 m of an osprey nest abandoned in 2010, and the other is around 2 km distant. It is<br />

not clear whether the same pair have attempted to nest in these nest sites both north and<br />

south of the reservoir, or more likely that two pairs are present. Ospreys do not defend a<br />

home range that includes <strong>for</strong>aging locations but they will however defend a nesting territory<br />

against ospreys of the same sex (Hardey et al. 2009). Given an adequate food supply,<br />

breeding ospreys often concentrate where nest sites are safest and most available and so it<br />

is likely that in this situation, the distance between nest sites is sufficient so that two osprey<br />

pairs would be able to nest simultaneously in <strong>for</strong>estry to the south of the reservoir in future<br />

years.<br />

12.5.12 The wind farm infrastructure will not cause any significant habitat loss <strong>for</strong> the pair nesting to<br />

the south of the Carron Valley Reservoir, and no loss of <strong>for</strong>aging habitat (open waterbodies<br />

and adjacent perching trees) will result from the proposed development <strong>for</strong> any pair.<br />

12.5.13 In conclusion, although the historic nest sites within the application site boundary will be<br />

unavailable, and despite a significant reduction in suitable nesting trees prior to construction,<br />

it is not possible to completely rule out the possibility that birds may attempt to nest in trees<br />

elsewhere within the application site boundary. There<strong>for</strong>e, a worst-case scenario would be<br />

the unlikely loss of one nesting pair to the site due to felling of trees within the wind farm’s<br />

footprint. This would result in a small magnitude effect on the regional population (4.8%<br />

loss), resulting in an effect of moderate or slight significance.<br />

Barn Owl<br />

12.5.14 The occupied barn owl nest box in 2010 was located at the edge of an area of <strong>for</strong>estry not<br />

considered <strong>for</strong> felling until after 2045.<br />

12.5.15 Based on the proposed site layout and construction methods, it is considered that the loss of<br />

a barn owl nest site (whether it be a nest box or natural nest) is about as likely as not (IPCC,<br />

2005). Results obtained from 2010 show that the nest box occupied in 2010 may be within<br />

an area of <strong>for</strong>est that would be cleared as part of a turbine’s footprint, although the actual<br />

extent of felling will likely depend on micrositing of turbines. No suitable <strong>for</strong>aging habitat will<br />

however be lost due to the development, with the species strongly preferring more open<br />

grassland and rough grass along field boundaries as <strong>for</strong>aging habitat, rather than maturing<br />

plantation. Unmitigated, the potential loss of one breeding pair to the NHZ population is<br />

considered to be of at worst small magnitude on a VOR of medium importance (regional<br />

conservation value) resulting in a long-term adverse effect on the regional population of slight<br />

significance.<br />

Greylag Goose<br />

12.5.16 All greylag goose records were of flocks of birds using the airspace above the application<br />

site, and there is no evidence to suggest that the species utilises any habitat within the<br />

application site boundary <strong>for</strong> feeding, roosting or breeding. As such, the effect of habitat loss<br />

to greylag goose is predicted to be negligible.<br />

Breeding Bird Assemblage<br />

12.5.17 Although 33.52 ha of <strong>for</strong>estry within the application site boundary will be cleared <strong>for</strong> turbines<br />

and other infrastructure, the key-holing technique used <strong>for</strong> turbine placement, and the usage<br />

of existing <strong>for</strong>est tracks <strong>for</strong> access routes means that little suitable nesting habitat will be lost<br />

in comparison to the overall area of the site. It is considered very likely that some nest sites<br />

<strong>for</strong> various passerines will be lost due to construction, but as much of the infrastructure will be<br />

placed in the <strong>for</strong>est interior, this will be of relatively poor quality habitat compared to <strong>for</strong>est<br />

edges and clearings which are preferred by many woodland species. There<strong>for</strong>e, although a<br />

small number of territories will be affected by habitat loss, it is not considered that these<br />

losses will be significant to any species above a local level.<br />

12.5.18 The creation of some woodland edge habitat due to turbine placement and access tracks<br />

may provide a small amount of extra <strong>for</strong>aging habitat <strong>for</strong> various species, including goshawk.<br />

12.5.19 As such, overall a small magnitude adverse effect is predicted on a VOR of medium<br />

importance (but see Table 12.17), resulting in a long-term adverse effect on the local<br />

population of slight significance.<br />

Disturbance<br />

12.5.20 Disturbance caused by construction operations may directly displace birds from breeding<br />

sites and/or <strong>for</strong>aging areas (although the actual habitat quality remains the same) <strong>for</strong> the<br />

duration of activities, thus potentially affecting breeding success or survival. In addition to<br />

these possible effects on individuals and populations, any wind farm construction work<br />

undertaken during the bird breeding season (mid-March to July or August, inclusive) carries a<br />

risk of illegal destruction or damage to occupied bird nests, as well as disturbance to Annex I<br />

and Schedule 1 species, if mitigation measures are not followed. The active nests of nearly<br />

all bird species (with the exception of some ‘pest’ species under certain conditions) are<br />

protected by the law and it is necessary to take measures to ensure compliance with the<br />

appropriate legislation (see Mitigation and Enhancement Measures section).<br />

12.5.21 As identified in Chapter 4: Description of the Proposed Development, the main construction<br />

period is likely to last <strong>for</strong> a total of 20 months, although the precise month or season in which<br />

the works will begin will depend on a number of factors including the timing of any planning<br />

permission being approved and the discharging of associated planning conditions.<br />

Osprey<br />

12.5.22 The proposed development will be within 100 m or so from possible nest site locations used<br />

within the application site boundary in 2010 and 2011, and more than 1 km from other nest<br />

sites, either natural or artificial, outside of the boundary. As has been established, the nest<br />

sites within the application site boundary will be unavailable at the time of construction, and<br />

so no disturbance effects are applicable. Nevertheless it is possible that a pair may attempt<br />

to nest in an alternative location nearby and so disturbance remains a possibility.<br />

Carron Valley Wind Farm<br />

12.5.23 A survey of expert opinion conducted by Ruddock and Whitfield (2007) revealed a wide range<br />

in the presumed typical disturbance distances <strong>for</strong> osprey, with static disturbance or alert<br />

distance (birds may call or appear more vigilant but remain in place) ranging from 100–150 m<br />

to 500-750 m, and an upper limit of active disturbance or flight initiation distance (birds take<br />

flight or move away) at 500-750 m.<br />

12.5.24 Taking a precautionary approach, if the upper limit of the alert distance <strong>for</strong> osprey (750 m) is<br />

considered appropriate as a disturbance buffer <strong>for</strong> active nest sites, no intact natural or<br />

artificial nest sites will be subject to construction disturbance, these being over 1 km distant.<br />

12.5.25 It is also considered very unlikely that <strong>for</strong>aging ospreys using Carron Valley Reservoir would<br />

be subject to significant disturbance which would impair <strong>for</strong>aging and there<strong>for</strong>e breeding<br />

success, particularly since birds are likely to have become habituated to human activities to<br />

some extent prior to construction due to <strong>for</strong>est clearance operations.<br />

12.5.26 Nevertheless, one breeding pair may be displaced in the short-term by construction activities<br />

if a nesting attempt is made in alternative habitat within 750 m of the wind farm footprint. This<br />

is considered to be an effect of small magnitude on a high sensitivity VOR, and there<strong>for</strong>e<br />

moderate or slight significance to the regional population. This is likely to be tolerable, since<br />

the regional population has recently followed an upward trend, which is expected to continue<br />

despite the loss of one pair.<br />

Barn Owl<br />

12.5.27 Barn owls are evidently tolerant of some human activity due to their selection of man-made<br />

structures <strong>for</strong> nesting, but where remote localities are used new disturbance from human<br />

activity may still be an issue. Ruddock and Whitfield’s (2007) expert opinion survey produced<br />

an upper limit of 50-100 m distance at which disturbance could occur, although many<br />

respondents considered that disturbance did not occur until a human was within 10 m of the<br />

nest.<br />

12.5.28 Although construction activity would be potentially located within or close to this disturbance<br />

range, it would be screened naturally by trees, and so it is considered unlikely that barn owls<br />

would be disturbed by any operations. As <strong>for</strong>aging activity would take place outside of the<br />

application site boundary, and during nocturnal and crepuscular periods when construction<br />

work will have ended, no disturbance will occur. Nevertheless, in a worst-case situation, the<br />

unlikely loss of one pair to the region would be of small magnitude on a receptor of<br />

medium/regional importance resulting in a long-term adverse effect on the regional<br />

population of slight significance.<br />

Greylag Goose<br />

12.5.29 All greylag goose records were of flocks of birds using the airspace above the application<br />

site, and there is no evidence to suggest that the species utilises any habitat within the<br />

application site boundary <strong>for</strong> feeding, roosting or breeding. As such, disturbance to greylag<br />

goose is predicted to be negligible.<br />

Breeding Bird Assemblage<br />

12.5.30 The breeding bird assemblage, which largely comprises a range of small passerine species,<br />

may be temporarily disturbed during the construction process. There is little empirical data<br />

on human disturbance of such species, although Ruddock and Whitfield (2007) suggested an<br />

active disturbance at 10–50 m or lower <strong>for</strong> crossbills, and an upper limit of 100-150 m <strong>for</strong><br />

passive disturbance. FCS (2006) guidance recommended a safe working distance <strong>for</strong> <strong>for</strong>est<br />

operations in the early stages of the breeding season, of 50-150 m <strong>for</strong> crossbill species.<br />

12.5.31 Localised short-term disturbance during the breeding season will there<strong>for</strong>e be very likely due<br />

to construction activities. In some cases this may lead to breeding failure or abandonment of<br />

a territory. As mentioned previously however, the number of territories likely to be affected is<br />

expected to be small and confined mainly to common woodland passerine species, with most<br />

activities taking place in the <strong>for</strong>est interior. It is considered very unlikely that any species’<br />

population will be adversely affected at any more than a local or district scale (low<br />

importance), and an effect of small magnitude results in a short-term adverse effect on the<br />

local or district population of slight significance at worst.<br />

Operation<br />

12.5.32 This section presents an evaluation of changes predicted during operational activities against<br />

the criteria outlined in the Evaluation Criteria section. The nature of the potential construction<br />

effects of the development are considered in turn <strong>for</strong> each VOR.<br />

Disturbance/Displacement<br />

12.5.33 The displacement effects attributable to wind farms are variable and are species, season and<br />

site-specific. As displacement effectively leads to exclusion from areas of suitable habitat, it<br />

can be regarded as being similar to habitat loss in its effect on birds, although often of greater<br />

extent. For breeding birds, the displacement from nesting habitat can lead to abandonment<br />

of the territory; the loss of <strong>for</strong>aging habitat may lead to a reduction in food supply, which in<br />

turn, can lead to reduced breeding success and/or survival rates or abandonment of the<br />

territory. The implications of such displacement at the population scale, in terms of the effect<br />

on the viability of the population, depends on the importance of the area from which birds are<br />

displaced and the capacity of alternative habitats to support displaced birds.<br />

12.5.34 Noise and visual disturbance to birds due to operational wind farms is considered to be of a<br />

much lower intensity than during construction/decommissioning phases, and is limited to brief<br />

maintenance activities as well as low-level normal operational turbine activity.<br />

Osprey<br />

12.5.35 Ruddock and Whitfield’s (2007) expert review deals with all <strong>for</strong>ms of disturbance to ospreys<br />

when considering likely disturbance-displacement distances. As the operational development<br />

constitutes a mainly predictable disturbance source compared to other activities (e.g. <strong>for</strong>estry<br />

felling), it is likely that there is some potential <strong>for</strong> ospreys to habituate to the development.<br />

Ospreys are known to tolerate similar man-made structures, and have nested on electricity<br />

pylons, with an example of this occurring in Highland Scotland (see SHETL, 2005).<br />

12.5.36 It is unlikely that, in future, any birds would be displaced by operational turbines unless<br />

nesting in very close proximity. The closest nest sites south of the Carron Valley Reservoir<br />

are more than 1 km distant and so beyond likely maximum displacement distance, as<br />

indicated by Ruddock and Whitfield (2007).<br />

12.5.37 Foraging activity will not take place within the application site boundary and so no<br />

displacement effects are predicted.<br />

12.5.38 Considering a worst-case scenario however, the loss of one pair from the regional population<br />

due to long-term displacement from nest sites would be of small magnitude and there<strong>for</strong>e of<br />

moderate or slight significance. This is likely to be tolerable due to the upward trend of the<br />

regional population.<br />

Barn Owl<br />

12.5.39 Already living close to man-made structures and using nest boxes, it is unlikely that barn owls<br />

will be displaced by turbines within the <strong>for</strong>estry, even if within 100 m from the nest. In support<br />

of this, from RPS post-construction monitoring of one wind farm in south Scotland there is<br />

evidence of successful breeding within 150 m of the closest turbine. Consequently, it is<br />

considered that disturbance-displacement effects on the conservation status of breeding barn<br />

owl are very unlikely and there<strong>for</strong>e negligible at any level.<br />

Greylag Goose<br />

12.5.40 All greylag goose records were of flocks of birds using the airspace above the application<br />

site, and there is no evidence to suggest that the species utilises any habitat within the<br />

application site boundary <strong>for</strong> feeding, roosting or breeding. As such, operational disturbance<br />

or displacement to greylag goose is predicted to be negligible.<br />

Breeding Bird Assemblage<br />

12.5.41 Although the breeding bird assemblage within the <strong>for</strong>estry is likely to be screened from<br />

operational turbines by trees, some birds may be displaced if in close proximity to turbines.<br />

There is conflicting evidence <strong>for</strong> the effects of wind farms on passerines but with the relevant<br />

studies being conducted in open moorland habitats where there would be no screening<br />

effects. Thus, <strong>for</strong> example, evidence of some avoidance of turbines by skylark was found in a<br />

multi-site correlative study (Pearce-Higgins et al. 2009), but in a second study involving<br />

comparisons between pre- and post-construction wind farm sites, as well as with control sites<br />

without turbines, skylark densities tended to be greater during construction and operational<br />

periods (Pearce-Higgins et al., 2012)<br />

12.5.42 Any displacement is there<strong>for</strong>e likely to be limited to the loss of some <strong>for</strong>aging or nesting<br />

habitat immediately beside the turbines and nesting along the edge of each turbine footprint.<br />

This is unlikely to affect any species’ population above a local scale (low importance), and an<br />

effect of medium magnitude (at worst) results in a short-term adverse effect on the local<br />

population of slight significance.<br />

Collisions with Turbines<br />

12.5.43 Collision of a bird with the turbine rotors is almost certain to result in the death of the bird.<br />

The effect of an individual loss on a population is influenced by several characteristics of the<br />

affected population, notably its size, density, recruitment rate (additions to the population<br />

through reproduction and immigration) and mortality rate (the natural rate of losses due to<br />

death and emigration). In general, the effect of an individual lost from the population will be<br />

greater <strong>for</strong> species that occur at low density, are relatively long-lived and reproduce at a low<br />

rate, e.g. larger raptors and geese. Conversely, the effect will often be insignificant <strong>for</strong> shortlived<br />

species with high reproductive rates found at high densities, including most passerines.<br />

12.5.44 At Carron Valley, few flights at potential collision height were recorded during the flight<br />

activity surveys (Table 12.11), and it was considered that there were too few ‘at risk’ flights<br />

recorded to allow robust CRM predictions to be made <strong>for</strong> all species except osprey and<br />

greylag goose. There<strong>for</strong>e, given the low frequency of ‘at-risk’ flights, it follows that mortality<br />

from collisions with turbines <strong>for</strong> all species other than osprey and greylag goose are likely to<br />

be negligible within the context of their respective national and regional populations and<br />

current baseline mortality. Although an isolated collision risk event over the lifespan of the<br />

development cannot be discounted <strong>for</strong> any species, this is considered very unlikely and so no<br />

significant effects are predicted. This is there<strong>for</strong>e negligible at any level.<br />

12.5.45 For osprey and greylag goose, CRM was undertaken to predict mortality levels from collisions<br />

with turbines, assessing this <strong>for</strong> the Vestas V90 turbine. This is the candidate turbine <strong>for</strong> the<br />

proposed development and has a 90 m rotor diameter and a hub height of 80m.<br />

12.5.46 For full details of CRM methodology see Appendix 12.1.<br />

Osprey<br />

12.5.47 Ospreys are likely to be at some risk of collision between late March and September only,<br />

this being the period over which the species is likely to be present in the Carron Valley area.<br />

As would be expected, the bulk of osprey flights recorded during flight activity surveys in<br />

summer were likely to comprise <strong>for</strong>aging activity centred over the Carron Valley Reservoir<br />

(Figure 12.4). There was however a smaller number of flights located above the application<br />

site boundary, which may relate to birds returning and leaving nest sites, either locally or<br />

further afield, since Carron Valley Reservoir is potentially a rich source of food <strong>for</strong> this<br />

species. There was some apparent connectivity with birds heading across the application<br />

site to waterbodies (or nest sites) further north, such as Earlsburn Reservoirs or North Third<br />

Reservoir.<br />

12.5.48 It is there<strong>for</strong>e likely that even if birds do not continue to nest within the application site in<br />

future years, there will be continued osprey activity as local birds and potentially those from<br />

the wider area will continue to use Carron Valley Reservoir to <strong>for</strong>age.<br />

12.5.49 Using the Vestas V90 turbine specifications it was predicted that 0.086 collisions per year<br />

would occur at a 98% avoidance rate (Table 12.15), which equates to approximately 2 birds<br />

during the proposed 25 year operational lifespan of the wind farm (see Appendix 12.1 <strong>for</strong><br />

further details).<br />

12.5.50 The likely loss of c.2 birds during the lifespan of the wind farm is unlikely to adversely affect<br />

the conservation status of the Central Scotland (regional) population, which is currently<br />

favourable. The loss of two birds represents 5% of the current Central Scotland breeding<br />

population of 21 pairs. Based on a background mortality rate of 9% (Forrester et al. 2007),<br />

this equates to an additional annual mortality of 1.6% and there<strong>for</strong>e would be an effect of<br />

small magnitude effect over a 25 year period. On a VOR of high importance this would result<br />

in an effect of moderate or slight significance on the regional population, which is likely to be<br />

tolerable due to the upward trend of the regional population.<br />

12.5.51 This effect is likely to be tolerable, since the population has shown a continued increase over<br />

the last decade, and coupled with relatively high productivity (Diagram 12.1), any losses<br />

would likely be replaced by young or currently non-breeding individuals from the larger<br />

regional pool of birds. Scottish birds can breed any time between three and seven years old<br />

(Forrester et al. 2007), suggesting there is likely to be a pool of non-breeding individuals in<br />

most years.<br />

Greylag Goose<br />

12.5.52 Although it is possible that some smaller flocks may have comprised local feral birds,<br />

individuals from the Icelandic breeding population of greylag goose are likely to have been<br />

recorded over the application site, and will be at some <strong>for</strong>m of collision risk in winter months.<br />

From flight activity results, this is particularly the case during autumn and spring migration<br />

periods. The bulk of the greylag goose flight activity was recorded parallel to the length of the<br />

Carron Valley Reservoir, indicating that birds may use this as a landmark en route to their<br />

<strong>for</strong>aging or roosting destinations. A small number of flights were however above the<br />

application site and so this species will likely continue to be at collision risk during the<br />

operational phase of the wind farm.<br />

12.5.53 Using the Vestas V90 turbine specifications it was predicted that 3.81 collisions per year<br />

would occur at a 99% avoidance rate (Table 12.15), which equates to approximately 95 birds<br />

during the lifespan of the wind farm (see Appendix 12.1 <strong>for</strong> further details).<br />

12.5.54 The most recent estimate <strong>for</strong> over-winter population of Icelandic greylag geese in Great<br />

Britain is 108,507 birds (Holt et al. 2011), and as this population is in favourable conservation<br />

status, the likely additional mortality of 95 birds would be of negligible magnitude, at a<br />

national and migratory flyway level (which is the geographical scale relevant to assessment<br />

of migratory species, according to SNH, 2006). With an annual mortality rate of 0.16 <strong>for</strong> this<br />

species (Trinder 2010), the additional annual mortality due to the proposed wind farm would<br />

represent an increase of c.0.02% to the overall mortality in any one year. An effect of<br />

negligible magnitude is there<strong>for</strong>e predicted resulting in an effect that is negligible.<br />

Barrier Effects<br />

12.5.55 Individual turbines or the wind farm as a whole may present a barrier to the movement of<br />

birds, restricting or displacing birds from much larger areas. Birds may avoid flying through<br />

or over wind farms by altering local flight paths or migration flyways.<br />

12.5.56 The effect this would have on a population is subtle, and difficult to predict with any certainty.<br />

If birds regularly have to fly over or around obstacles or are <strong>for</strong>ced into sub-optimal habitats,<br />

this may result in greater energy expenditure (Drewitt and Langston 2006). By implication,<br />

this will reduce the efficiency with which they accumulate reserves, potentially affecting their<br />

survival or breeding success. During the lifetime of the wind farm, there is evidence that<br />

some birds may habituate to the presence of turbines (e.g. Madsen and Boertmann, 2008),<br />

and so this effect is likely to be greatest in the short-term.<br />

12.5.57 Although there is evidence that the adjacent Carron Valley Reservoir is important <strong>for</strong> <strong>for</strong>aging<br />

species (e.g. osprey, waterfowl), and also as a landmark <strong>for</strong> migratory geese, relatively few<br />

flights were recorded over the application site to and from the reservoir.<br />

12.5.58 The site may <strong>for</strong>m part of an occasional commuting route <strong>for</strong> the local osprey within a regular<br />

<strong>for</strong>aging range of 20 km (Hardey et al. 2009), but due to the overall distance that ospreys can<br />

travel, a slight detour is unlikely to significantly affect the ability of birds to obtain fish and the<br />

resulting survival and productivity rates of the regional population. If ospreys continue to<br />

breed somewhere within the application site boundary however, there may be some small<br />

barrier effect between the nest site and the reservoir, with the species being a central-placed<br />

<strong>for</strong>ager during the breeding season. It is unlikely that turbines close to the reservoir will<br />

prevent birds from accessing the reservoir <strong>for</strong> <strong>for</strong>aging, but the cumulative effect of detours<br />

around turbines across the whole season may potentially reduce productivity <strong>for</strong> this pair.<br />

12.5.59 An adverse effect on the conservation status of the regional population is however<br />

considered unlikely, with relatively high productivity elsewhere compensating <strong>for</strong> a reduction<br />

to any pair. This is there<strong>for</strong>e an effect of small magnitude at worst on a species of high<br />

importance, resulting in an effect of slight significance at a regional level.<br />

12.5.60 Greylag goose apparently use Carron Valley Reservoir as part of an occasional migratory<br />

route, but only rarely transit across the application site. Barrier effects are there<strong>for</strong>e very<br />

unlikely <strong>for</strong> this species, particularly in comparison with overall migratory distances travelled.<br />

This is of negligible magnitude and there<strong>for</strong>e negligible at any level.<br />

12.5.61 In general, no evidence was found that the application site lies on an important route <strong>for</strong> any<br />

other species, or between nest site and feeding areas <strong>for</strong> centrally-placed breeding species.<br />

The proposed development is there<strong>for</strong>e unlikely to present a significant barrier effect to the<br />

overall breeding bird assemblage. Small passerine species will be able to continue to <strong>for</strong>age<br />

in the area surrounding their nest unaffected. This is of negligible magnitude and there<strong>for</strong>e<br />

negligible at any level.<br />

Decommissioning<br />

12.5.62 Potential disturbance effects associated with decommissioning are presumed to be the same<br />

as those identified <strong>for</strong> construction, albeit taking place over a shorter timescale at the end of<br />

the operational lifetime of the wind farm. This assumes that there is no permanent<br />

displacement of birds from the wind farm due to disturbance effects, although activities will be<br />

subject to the same legal restrictions to avoid the unlawful destruction of nest sites, or<br />

disturbance to protected species.<br />

12.5.63 Given the similarities between the effects of construction and decommissioning, the effects of<br />

decommissioning are not considered separately <strong>for</strong> each species.<br />

12.6 Mitigation and Enhancement Measures<br />

12.6.1 Whilst the above impact assessment does not predict any effects of greater than moderate or<br />

slight significance (and likely to be tolerable in all cases), the predictive nature of the<br />

assessment means that if no mitigation measures were incorporated into the final design of<br />

the development, then significant effects on some VORs found within the study area cannot<br />

necessarily be ruled out. Mitigation and habitat enhancement measures have there<strong>for</strong>e been<br />

identified which would maximise the likelihood of any construction or operational effects being<br />

slight or lower and increase the opportunity <strong>for</strong> enhancement of the baseline situation where<br />

relevant. These measures are discussed below.<br />

Best Practice Regarding Breeding Birds<br />

12.6.2 There is a need to follow best practice during the construction of the development to ensure<br />

compliance with the legislation concerning disturbance to breeding birds.<br />

Legislative Protection<br />

12.6.3 Under the Wildlife and Countryside Act 1981 as amended by the Nature Conservation<br />

(Scotland) Act 2004, it is an offence with only limited exceptions, to:<br />

• intentionally or recklessly take, interfere with, damage or destroy the nest of any wild<br />

bird whilst it is in use or being built;<br />

• intentionally or recklessly take, interfere with or destroy the egg of any wild bird; or<br />

• intentionally or recklessly disturb any wild bird listed on Schedule 1 while it is nest<br />

building, or at (or near) a nest containing eggs or young, or disturb the dependent<br />

young of such a bird.<br />

12.6.4 Best practice will be necessary to reduce the possibility of illegal damage, destruction or<br />

disturbance to occupied bird nests during the construction phase (or during any maintenance<br />

work in the operational phase). Three best practice measures outlined below will be adopted:<br />

the use of an Ecological Clerk of Works (ECoW), and the timing of construction activities and<br />

visual deterrents.<br />

Ecological Clerk of Works<br />

12.6.5 Compliance with the law (<strong>for</strong> example to avoid intentional nest destruction of any species) will<br />

be supported by the appointment of a suitably experienced ornithologist as ECoW to carry<br />

out pre-construction surveys and locate any active nests close to construction works shortly<br />

be<strong>for</strong>e these commence. There will be a clear line of responsibility <strong>for</strong> ensuring these<br />

measures are adhered to, which will be specified in the Health, Safety and Environmental<br />

Management System (HSEMS) to which the appointed contractor will be required to adhere<br />

(see Appendix 4.4).<br />

Timing of Construction Activities and Visual Deterrents<br />

12.6.6 If feasible, site clearance and construction activities will be timed to take place outside of the<br />

main breeding season so as to avoid nest destruction and disturbance to breeding birds. For<br />

the majority of birds the main breeding season extends from mid-March to at least the end of<br />

July (depending on the species concerned), and <strong>for</strong> osprey, young birds may still be present<br />

around the nest into August. Common crossbills, a Schedule 1 species, were recorded in<br />

<strong>for</strong>estry and may breed in this area. It should however be noted that the timing of breeding in<br />

this species is determined by the availability of conifer seeds and nesting may take place<br />

during the winter months (Forrester et al., 2007; Currie & Elliott 1997).<br />

12.6.7 SNH (2011) recognises that avoiding construction work within the breeding season <strong>for</strong> birds<br />

may not be possible, as the season coincides with the best weather <strong>for</strong> construction. In this<br />

case, activities will aim to commence be<strong>for</strong>e mid-March wherever possible. By timing<br />

construction activities to start be<strong>for</strong>e the breeding season, birds will have an opportunity to<br />

take potential disturbance into account in the process of selecting a nest site, and those birds<br />

with a choice of nest sites may select an alternative nest site <strong>for</strong> that season.<br />

12.6.8 In areas where work is unavoidable during the breeding season, deterrents may be placed<br />

within a restricted area well in advance so that birds will not choose to nest within that<br />

locality. Examples of deterrence include using bird scarers, reflective tape or ribbons on posts<br />

or physical removal of habitat (e.g. removing trees or turf from access track routes etc to<br />

deter birds from breeding there) (SNH, 2011). Physical alteration to the habitat prior to the<br />

bird breeding season is SNH’s least favoured option due to the direct and indirect effects it<br />

may have on other interests, and would there<strong>for</strong>e only be used should no other options be<br />

viable.<br />

12.6.9 Limiting construction activity in close proximity to breeding birds during certain periods of the<br />

day can reduce the effects on these species by minimising exposure to disturbance.<br />

Avoiding the periods two hours be<strong>for</strong>e and after dawn and dusk can benefit <strong>for</strong>aging barn owl<br />

near the application site boundary, and although not present during baseline surveys, if any<br />

black grouse leks are recorded, a similar measure will be required within approximately<br />

500 m of any such site if present in the future. Such restrictions will be specified in the<br />

HSEMS (see Appendix 4.4).<br />

Pre-construction Surveys<br />

12.6.10 Following the implementation of any appropriate deterrent devices prior to the breeding<br />

season, surveys will be undertaken by an ECoW or other suitably-qualified person, to locate<br />

nesting birds and lekking black grouse in the vicinity of construction works to ensure that<br />

none are disturbed.<br />

12.6.11 Any active nests found will be cordoned off to a suitable distance <strong>for</strong> the species concerned<br />

(up to 20 m <strong>for</strong> woodland and scrub nesters and up to 50 m <strong>for</strong> open-ground nesting species)<br />

and construction operations delayed within the cordon until the young have fledged and the<br />

nest becomes vacant. This will be confirmed by the ECoW prior to the recommencement of<br />

construction.<br />

12.6.12 Larger buffer distances will be used to avoid spatial overlap of construction activities and<br />

breeding attempts of Schedule 1 and/or Annex I species, which are subject to additional<br />

protection relating to disturbance during the breeding season. Exact distances are<br />

dependent on site-specific characteristics (e.g. topography, screening), but will be based on<br />

those recommended in Ruddock and Whitfield (2007) and other relevant papers. An<br />

agreement will be reached with SNH prior to construction activities commencing.<br />

12.6.13 If nest building activity of Schedule 1 species is seen within a cordoned area, continued<br />

deterrence would constitute disturbance and is an offence under the Wildlife and Countryside<br />

Act, so would be stopped immediately. In this case, and also if birds are nesting outside of<br />

controlled areas but in the opinion of the ECoW within possible disturbance zones, the work<br />

will either be re-scheduled or the nest site cordoned-off and destruction prevented.<br />

12.6.14 In such situations, SNH recommends that pre-construction breeding bird surveys take place,<br />

with works then being programmed to avoid disturbance. A number of surveys may there<strong>for</strong>e<br />

be required as construction progresses through the site.<br />

Mitigation and Enhancement <strong>for</strong> Osprey and Barn Owl<br />

12.6.15 Specific objectives will be made <strong>for</strong> osprey if required. In conjunction with the Central<br />

Scotland Raptor Study Group, artificial nests and/or nesting plat<strong>for</strong>ms would be proposed<br />

within suitable habitat in the local area, beyond recognised disturbance-displacement zones<br />

from the proposed development or other projects, and within areas that are likely to facilitate<br />

the continued expansion of the Central Scotland population (e.g. on the shore-side of Carron<br />

Valley Reservoir or in the <strong>for</strong>estry to the south). Site selection and construction will follow<br />

relevant best practice guidelines (e.g. http://www.roydennis.org/osprey/index.asp?id=90).<br />

The aim will be to help continue the upward population trend and range expansion of osprey<br />

numbers in central Scotland.<br />

12.6.16 Additional barn owl boxes will be placed in suitable habitat, away from the effects of the wind<br />

farm, if any current sites are to be disturbed. This will help reverse the habitat loss and<br />

fragmentation <strong>for</strong> this species of conservation concern.<br />

12.6.17 In conjunction with creation of new nest sites, <strong>for</strong>est clearance undertaken by FCS in<br />

advance of the wind farm construction programme will also be undertaken with ospreys in<br />

mind. Surveys will be conducted prior to wind farm construction to determine the remaining<br />

locations of any potential nesting trees within displacement or high collision risk zones on<br />

Cairnoch Hill, and these will be felled or the crowns removed during the non-breeding<br />

season. The extent and suitability of this measure will be determined by the ECoW in<br />

conjunction with FCS and will include discussions with SNH and the Central Scotland Raptor<br />

Study Group if considered appropriate.<br />

12.7 Assessment of Residual Effects<br />

12.7.1 A summary of the residual effects on ornithology discussed in this section is presented in<br />

Table 12.18.<br />

Osprey<br />

12.7.2 Without suitable mitigation measures implemented, it is predicted that the wind farm would<br />

result in short- and long-term effects of moderate to slight significance on the regional<br />

population (displacement of one pair, and/or mortality of c.2 birds during the proposed 25<br />

year operational period).<br />

12.7.3 There will be a need to carry out pre-construction surveys and continue to consult with the<br />

Central Scotland Raptor Study Group about the current location of any osprey nests,<br />

particularly as the species appears to be expanding in numbers and range. If ospreys again<br />

occupy a site within or close to the proposed wind farm footprint, this may be subject to<br />

removal by tree-felling between September and late-March to avoid disturbance to breeding<br />

birds and their nest. The effect of this will be mitigated by creation of alternative nest sites<br />

away from the wind farm’s influence prior to any nest removal (e.g. within <strong>for</strong>estry on the<br />

south side of the reservoir).<br />

12.7.4 Dissuasion from nesting in close proximity to turbines by removing suitable trees will mean<br />

that collision risk will be reduced, since much osprey flight activity would normally take place<br />

in the immediate area around the nest site. Similarly, any barrier effect caused by turbines<br />

close to the nest will be removed.<br />

12.7.5 These measures will reduce any short- or long-term effects on the conservation status of the<br />

species at the regional/NHZ scale to at worst slight significance, and there<strong>for</strong>e residual<br />

effects are not considered to be significant in terms of the EIA Regulations<br />

Barn Owl<br />

12.7.6 Without suitable mitigation measures implemented, the proposed wind farm may potentially<br />

affect at least one barn owl breeding pair due to the removal of a nest box, or excessive<br />

disturbance associated with nearby construction activities.<br />

12.7.7 Nest site removal will be mitigated by constructing alternative nest boxes in suitable habitat<br />

areas (<strong>for</strong>est edge adjacent to open grassland <strong>for</strong> <strong>for</strong>aging) away from disturbance. In the<br />

longer-term, suitably located broadleaved planted areas may also provide natural nesting<br />

habitat <strong>for</strong> the species.<br />

12.7.8 Disturbance effects on this species are likely to be limited to within 100 m of the nest, but<br />

effects will be mitigated by avoiding activities in this zone during the breeding season (March<br />

to August inclusive) if preconstruction surveys show that barn owls are utilising a nest box or<br />

any natural nest site. Where considered necessary by the ECoW, construction activities will<br />

be avoided in this area in the two hours prior to dawn and after dusk to aid <strong>for</strong>aging.<br />

12.7.9 These mitigation measures will remove any short- or long-term effects on the conservation<br />

status of the species at the NHZ scale (negligible magnitude) and there<strong>for</strong>e residual effects<br />

are predicted to be negligible at any level.<br />

Greylag Goose<br />

12.7.10 Only collision risk and barrier effects were considered of any potential issue <strong>for</strong> this species,<br />

and the impact assessment concludes that no effects would be significant at any level. No<br />

specific mitigation measures are there<strong>for</strong>e proposed <strong>for</strong> this species, and the predicted<br />

residual effect remains negligible.<br />

Breeding Bird Assemblage<br />

12.7.11 No significant effects are predicted at anything greater than local or district level.<br />

Nevertheless, generic measures outlined above in Mitigation and Enhancement Measures<br />

are proposed in order to help prevent nest destruction to all species during the breeding<br />

season, whilst some additional woodland edge habitat will be created from the felling required<br />

<strong>for</strong> turbine placement. As such residual effects are predicted to be negligible <strong>for</strong> any<br />

breeding species .<br />

12.8 Cumulative Effects<br />

Background Guidance<br />

12.8.1 The above sections have considered the implications of the proposed wind farm on VORs in<br />

isolation from potential effects of other projects and activities. The EIA Regulations also<br />

require the potential <strong>for</strong> cumulative effects to be assessed.<br />

12.8.2 According to the latest SNH (2012b) guidance, an assessment of cumulative effects<br />

associated with a specific development proposal should encompass the effects of the<br />

proposal in combination with:<br />

• existing development, either built or under construction;<br />

• approved development, awaiting implementation; and<br />

• proposals awaiting determination within the planning process with design in<strong>for</strong>mation<br />

in the public domain. Proposals and design in<strong>for</strong>mation may be deemed to be in the<br />

public domain once an application has been lodged, and the decision-making authority<br />

has <strong>for</strong>mally registered the application.<br />

Species to be Considered<br />

12.8.3 SNH (2012b) stipulates that “the key principle <strong>for</strong> all cumulative impact assessments is to<br />

focus on the likely significant effects and in particular those which are likely to influence the<br />

outcome of the consenting process”. SNH there<strong>for</strong>e only seeks cumulative impact<br />

assessments “where it is considered that a proposal could result in significant cumulative<br />

impacts which could affect the eventual planning decision”.<br />

12.8.4 A list of protected species potentially at risk of effects from onshore wind farms (Annex C,<br />

SNH, 2012) includes the following VORs at Carron Valley: osprey and greylag goose. Barn<br />

owl is not on this list and is there<strong>for</strong>e excluded from the cumulative assessment (it is<br />

considered unlikely that this species will be affected by the proposed wind farm in any event).<br />

None of the other species present in lower numbers at Carron Valley are likely to be at risk of<br />

cumulative effects due to very low site usage (waterfowl, raptors), high regional populations<br />

(common passerines), and the minor effects that have been mitigated to an acceptable level<br />

(e.g. cuckoo, curlew, non-breeding raptors such as goshawk or merlin).<br />

12.8.5 Predicted greylag goose collision rates are negligible compared to the population size and<br />

the background mortality rate <strong>for</strong> the Icelandic breeding population (representing an<br />

additional 0.02% to the annual mortality of the population that winters in Great Britain), and<br />

so it is considered very unlikely that this will materially contribute to an overall significant NHZ<br />

or national cumulative collision risk in any way. Barrier effects are also likely to be negligible.<br />

As such this species is excluded from the cumulative assessment.<br />

12.8.6 Osprey is there<strong>for</strong>e the sole species that may be subject to cumulative effects. Based on the<br />

impact assessment, slight adverse residual effects are predicted <strong>for</strong> this species at a regional<br />

level due to collision risk and barrier effects.<br />

Scope of Projects and Activities<br />

12.8.7 For wind farms which do not have an effect on designated sites, SNH (2006) guidance<br />

highlights the relevance of the NHZ as the basis <strong>for</strong> the geographical range selection of<br />

cumulative effects. Such a scope of work however may be extensive in nature and so SNH<br />

recognises that “it is unrealistic to insist on a cumulative assessment if the relevant<br />

in<strong>for</strong>mation is not reasonably available”.<br />

12.8.8 The cumulative assessment of the effects of the proposed development has there<strong>for</strong>e<br />

considered, where in<strong>for</strong>mation was available, all other wind farms (constructed, consented or<br />

proposed) within the West Central Belt NHZ, and any other activities subject to the EIA<br />

Regulations that may affect the ornithological interests of the area.<br />

12.8.9 After a desk-based research exercise, it was concluded that the only development types of<br />

significant scale to potentially affect osprey (collision risk and barrier effects) were other wind<br />

farms. The latest available Wind Farm Footprint Map of Scotland 11 on the SNH website (July<br />

2011 version) as well as in<strong>for</strong>mation from Stirling Council and other council’s websites was<br />

used to determine all other wind farm projects within this potential zone of influence. Results<br />

showed that there are 62 wind farm projects at all stages within the NHZ.<br />

12.8.10 As no readily-accessible dataset was available on other wind farms, to refine the assessment<br />

to a manageable level, wind farms with three or fewer turbines (classified as small-scale wind<br />

energy projects by SNH, 2011) were excluded due to the very low likelihood that they will<br />

materially contribute to a cumulative significant effect on ornithology at a NHZ level.<br />

12.8.11 Proposed wind farms that have been rejected by the competent authority or withdrawn by a<br />

developer are also not included in the cumulative assessment as any future amended layout<br />

would have different ornithological effects. For projects at the scoping stage of the EIA<br />

process, baseline ornithological surveys are either ongoing or have not become publically<br />

available to date. Potential effects are there<strong>for</strong>e unknown, and so these projects have also<br />

been excluded from the cumulative assessment.<br />

Carron Valley Wind Farm<br />

Cumulative Collision Mortality<br />

12.8.12 The effect of collision risk to ospreys due to the proposed wind farm alone was not<br />

considered significant in comparison with natural mortality rates. However, when considered<br />

in conjunction with other sources of additional mortality, especially from other wind farms, it<br />

may initiate a population decline that cannot be reversed unless the adverse effect is<br />

removed.<br />

12.8.13 When assessing cumulative mortality from multiple developments, SNH (2012b) notes that<br />

simply summing collision mortality across all developments may overestimate cumulative<br />

mortality, as once a bird has been removed from a population due to collision with one<br />

development, it cannot collide again. This is particularly pertinent where population sizes are<br />

small (i.e. the regional osprey population) and mortality can represent a significant proportion<br />

of the population. With the Central Scotland population of 21 breeding osprey pairs in an<br />

area of multiple wind farm developments, then if one pair is lost due to collision mortality with<br />

one wind farm, that will mean that there are fewer birds remaining in the population that are<br />

then subject to a risk of further collision mortality.<br />

12.8.14 Within an osprey’s <strong>for</strong>aging range of 20 km from the nest, there are two wind farms in<br />

proximity to Carron Valley that are operational (Earlsburn and Craigengelt), two that have<br />

been approved (Earlsburn North and Greengairs), and three in the application process<br />

(Craigannet , Rullie, and Muirpark).<br />

12.8.15 Of these, there was no mention of osprey activity in the respective <strong>ES</strong> chapters <strong>for</strong> Muirpark,<br />

Forthbank and Greengairs. A summary of activity at the remaining sites is provided below.<br />

Earlsburn and Earlsburn North Wind Farms<br />

12.8.16 The nine turbine Earlsburn North Wind Farm is a consented extension to the operational<br />

14 turbine Earlsburn Wind Farm. The original site is adjacent to the northern site boundary of<br />

Carron Valley, and the extension is approximately 1.8 km to the north at its closest point.<br />

12.8.17 The Earlsburn North <strong>ES</strong> (RDC, 2008) provides a summary of osprey activity at both this site<br />

and the original Earlsburn Wind Farm site.<br />

12.8.18 A total of 28 osprey flights were observed during VP watches, concentrated over the<br />

Earlsburn Reservoirs (2 km north of Carron Valley) and over Ling Hill (over 2 km northeast of<br />

Carron Valley) on a flight path along the valley between the Fintry Hills and the Gargunnock<br />

Hills. Although no breeding activity was observed, birds were carrying food probably to nest<br />

sites to the north.<br />

12.8.19 It was concluded that the activity of the osprey observed at Earlsburn North appeared to be of<br />

birds <strong>for</strong>aging over the Earlsburn reservoirs to the south east of that development site or of<br />

birds travelling to and from Carron Valley Reservoir <strong>for</strong>aging then travelling back to nest sites<br />

to the north of the development site. There was an apparent pattern to the commuting:<br />

ospreys followed the valley between the Gargunnock Hills and the Fintry Hills along the<br />

course of the upper reaches of the Endrick Water and over Burnfoot Cottage ruin and Ling<br />

Hill.<br />

12.8.20 The CRM used an avoidance rate of 98%, and predicted 0.085 collisions per year (equivalent<br />

to 1 collision every 11.8 years).<br />

12.8.21 The original Earlsburn <strong>ES</strong> (RDC, 2003) predicted a collision rate of 0.002 birds per year,<br />

giving a combined total of 0.087 birds per year at the two sites (one collision every 4.6 years).<br />

Carron Valley Wind Farm<br />

Craigannet Wind Farm<br />

12.8.22 This seven turbine wind farm, adjacent to the eastern site boundary of the proposed Carron<br />

Valley Wind Farm site, is in the application stage. The <strong>ES</strong> (Lomond Energy, 2012) showed<br />

that osprey were confirmed as breeding within the survey area in 2011. This is likely to have<br />

been one of the nest sites recorded at Carron Valley in 2011. Although there was frequent<br />

flight activity observed, the majority of it was outwith the Craigannet site boundary, and only<br />

three osprey flights came within 200 m of the turbine layout during the entire survey period<br />

(April 2010 to April 2011). Due to the low level of activity over this area, CRM was not<br />

undertaken.<br />

Rullie Wind Farm<br />

12.8.23 This ten turbine wind farm is approximately 6.5 km east of the proposed Carron Valley Wind<br />

Farm site. The <strong>ES</strong> (Community Windpower, 2011) detailed survey work carried out in 2008-<br />

09. Osprey was recorded fishing occasionally at Carron Valley Reservoir, but recorded on<br />

only one survey, fishing on Loch Coulter Reservoir and flying briefly over the wind farm site<br />

on three occasions. Collision rate calculations predicted one collision every 363 years at<br />

98% avoidance rate.<br />

Conclusions<br />

12.8.24 Within the <strong>for</strong>aging range of birds that may use the airspace over Carron Valley (particularly<br />

to <strong>for</strong>age within Carron Valley Reservoir), there are five operational and planned wind farms<br />

that may contribute to a cumulative collision risk. From CRM predictions in respective <strong>ES</strong>s, a<br />

total annual mortality of 0.15 birds per year was predicted (Table 12.17), which equates to<br />

one bird every 6-7 years.<br />

12.8.25 Taking the background mortality rate <strong>for</strong> this species as being 0.09, this cumulative loss<br />

would result in an increase in background mortality to the NHZ breeding population of 4.0%<br />

(assuming all collisions would be on breeding birds). This would represent a small magnitude<br />

of effect on a species of high importance, resulting in an overall cumulative effect of slight<br />

adverse significance at a regional level.<br />

12.8.26 It is also possible that other local osprey populations within the larger Central Scotland<br />

population may be at risk from collisions from other wind farm projects, thereby contributing<br />

to a greater cumulative effect at a NHZ level. A quantitative assessment of all wind farms<br />

Carron Valley Wind Farm<br />

within the NHZ is beyond the reasonable scope of this assessment, and would not<br />

necessarily reflect an accurate cumulative collision risk <strong>for</strong> reasons outlined in SNH (2012b).<br />

Nevertheless, although distribution of ospreys in relation to all wind farms is unknown, further<br />

mortality increases cannot be discounted. Taking a precautionary approach, the overall<br />

cumulative collision mortality at a NHZ level is there<strong>for</strong>e considered to be of moderate<br />

significance.<br />

12.8.27 This level of significance is however considered to be tolerable due to the apparent<br />

expansion of the species in the NHZ and in southern Scotland as a whole. This current rate<br />

of increase is likely to be able to compensate <strong>for</strong> any losses to the breeding population due to<br />

collisions, from a likely pool of young non-breeders replacing any lost adults.<br />

Cumulative Barrier Effects<br />

12.8.28 Barrier effects are recognised as being more difficult to quantify than other effects. SNH<br />

(2012b) advises that one approach is to identify the proportion, or percentage, of a species’<br />

dispersal or migration route that is occupied by wind farm developments.<br />

12.8.29 In the case of breeding osprey, where <strong>for</strong>aging birds that are local or from the wider area may<br />

incur a daily ‘detour’ to reach the Carron Valley Reservoir <strong>for</strong> example, this may add<br />

significantly over time to the overall expenditure of energy.<br />

12.8.30 Compared to other identified effects on wind farms, there is less consistency in <strong>ES</strong>s on<br />

barrier effects, with only some projects including any such assessment.<br />

12.8.31 It was concluded by RDC (2008) that osprey flight lines could be slightly displaced due to the<br />

barrier effect of the Earlsburn North turbines, potentially resulting in a ‘Slight Adverse’ effect.<br />

It was thought that the turbines to the south west on Ling Hill could potentially disrupt the<br />

ospreys commuting route to and from <strong>for</strong>aging nesting areas. The six proposed turbines on<br />

and to the north west of Ling Hill lie on a line which is similar to the recorded osprey<br />

commuting route. Displacement could either make birds fly further to the north east or to the<br />

south west of the six turbines. This is however only going to require a small deviation to their<br />

flight route, with the majority of these commuting flights recorded just to the south west of the<br />

proposed turbine locations.<br />

12.8.32 With birds from the north already being displaced by Earlsburn and Earlsburn North Wind<br />

Farms, it is unlikely that Carron Valley would add any additional barrier effect, with overall<br />

increase in <strong>for</strong>aging distance being negligible. Evidence from the Earlsburn North survey<br />

work suggests that commuting birds make use of the Endrick Water valley heading northwest<br />

from Carron Valley, rather than crossing the wind farm sites on a regular basis. It is unlikely<br />

there<strong>for</strong>e that a significant cumulative barrier effect will result on the local osprey population<br />

within the 20 km <strong>for</strong>aging range.<br />

12.8.33 It is not known whether any other osprey pairs within the NHZ may be subject to potential<br />

barrier effects, but in general the threat to this species is likely to be low due to its capability<br />

of <strong>for</strong>aging over a wide area and utilisation of a number of waterbodies within range. As<br />

such, the predicted cumulative barrier effect at a NHZ level is considered to be of slight<br />

significance. This is likely to be tolerable due to the availability of alternative habitat if<br />

required, <strong>for</strong> both <strong>for</strong>aging and nesting, and the current high productivity rate of birds within<br />

the Central Scotland population.<br />

Carron Valley Wind Farm<br />

12.9 Summary of Effects<br />

12.9.1 The baseline surveys conducted to in<strong>for</strong>m the EIA have identified an ornithological<br />

assemblage within the vicinity of the development that is typical of plantation and upland<br />

habitats of Central Scotland, with usage within the application site boundary being confined<br />

mainly to relatively common breeding passerines and raptors. Although a number of species<br />

were identified as being of conservation concern, most were not considered significant within<br />

the context of their respective regional or national populations, and further consideration was<br />

not required within the EIA. This left four VORs to be taken into account in the impact<br />

assessment: osprey, greylag goose, barn owl and the general breeding bird assemblage.<br />

12.9.2 The impact assessment identified potential effects on these VORs associated with the<br />

development during the construction and operation phases (habitat loss, disturbance,<br />

displacement, collision risk and barrier effects). These are summarised in Table 12.18.<br />

12.9.3 It was concluded that when mitigation and enhancement measures were considered, there<br />

were no predicted significant effects due to the Carron Valley Wind Farm on any VOR, either<br />

alone, or cumulatively with other projects or activities.<br />

12.9.4 The confidence in the predicted effects should however consider the following limitations of<br />

baseline surveys and assessment:<br />

• The baseline surveys were designed to be carried out during hours of daylight, as well<br />

as at dawn and dusk. It is there<strong>for</strong>e possible that nocturnal migratory movements may<br />

not have been recorded, and that some species (e.g. geese, swans, passerines) may<br />

be at greater risk of collision and barrier effects than identified in the impact<br />

assessment. The likelihood of this is low however, based on the low number of<br />

records <strong>for</strong> such species during dusk and dawn periods, and also the greater<br />

probability of migratory flights taking place both over the Carron Valley Reservoir, and<br />

at high altitude, well above rotor height, and thereby negating the risk of any collision<br />

or barrier effects.<br />

• The baseline situation may alter from that predicted by the time Carron Valley<br />

construction commences. Although the phased <strong>for</strong>estry felling plan is likely to occur as<br />

planned, unpredictable additional felling due to wind blow effects may be required in<br />

the meantime. Nevertheless, this is not expected to materially affect predictions in this<br />

assessment.<br />

13 Hydrology, Hydrogeology and Ground Conditions<br />

13.1 Introduction and Overview<br />

13.1.1 This chapter assesses the potential hydrological, hydrogeological and geological effects<br />

associated with the proposed Carron Valley Wind Farm. It details the existing baseline<br />

situation in terms of hydrological, hydrogeological and geological conditions present within<br />

and adjacent to the proposed site boundary. An assessment of effects has been undertaken<br />

<strong>for</strong> the construction, operation and decommissioning stages of the proposed wind farm,<br />

identifying associated activities that have the potential to affect the existing baseline situation.<br />

13.1.2 Effects on hydrology, hydrogeology and geology have the potential to result in secondary<br />

ecological effects on habitats or species. Effects on ecological receptors (non-avian) are<br />

considered in Chapter 11: Terrestrial Ecology. In addition, in<strong>for</strong>mation to in<strong>for</strong>m the need <strong>for</strong><br />

Appropriate Assessment has been completed and presented in Appendix 11.6 in relation to<br />

potential effects on the Endrick Water Special Area of Conservation (SAC) and should be<br />

read in conjunction with this chapter.<br />

Key Issues<br />

13.1.3 The following potential issues have been addressed as part of this assessment:<br />

• Effects on surface runoff characteristics;<br />

• Effects on river flow and flooding;<br />

• Effects on peat hydrological regime;<br />

• Effects of erosion and sedimentation;<br />

• Effects of contamination from oils, fuels, concrete etc on surface water quality;<br />

• Effects on local geology;<br />

• Effects on groundwater levels and hydrological regime;<br />

• Effects of contamination from oils, fuels, concrete etc. on groundwater quality;<br />

• Effects on water resources (private and public water supplies).<br />

Study Area<br />

13.1.4 The study area includes the area occupied by the proposed wind farm as well as surrounding<br />

areas. These areas include the catchments associated with all rivers and waterbodies within<br />

the site, including the Carron Valley Reservoir, the River Carron and the Endrick Water, as<br />

shown in Figure 13.1. In this assessment, other areas and developments have been<br />

considered where hydrological linkages exist or cumulative effects may arise.<br />

13.2 Methodology<br />

Approach<br />

13.2.1 In order to effectively assess any potential effects arising due to the construction, operation or<br />

decommissioning of the proposed wind farm on the hydrology, hydrogeology and ground<br />

conditions both within and adjacent to the site, the following activities have been undertaken:<br />

• Consultation with relevant statutory and non-statutory bodies;<br />

• Establishing baseline conditions on site via a detailed desk study, site visits and<br />

investigation of ground conditions at the proposed site;<br />

• Evaluating the sensitivity of the baseline conditions to change;<br />

• Evaluating the magnitude of the potential effects of the proposed wind farm and how<br />

these might affect the site baseline conditions;<br />

• Evaluating the significance of potential effects through consideration of the sensitivity<br />

of baseline features, the magnitude of potential effects and the probability of the effects<br />

occurring;<br />

• Identifying suitable measures to avoid, reduce or offset any potentially significant<br />

adverse effects resulting from the proposed wind farm, including the implementation of<br />

design measures;<br />

• Evaluating any residual significance of the potential effects following mitigation.<br />

Baseline Methodology<br />

Desktop Study<br />

13.2.2 The purpose of the desktop study is to establish the baseline conditions within and adjacent<br />

to the site in order to:<br />

• Identify the key surface water hydrological features, including watercourses, lochs,<br />

reservoirs and springs;<br />

• Collate historic hydrological flow and flooding data <strong>for</strong> the immediate area and main<br />

downstream watercourses;<br />

• Establish the hydromorphological conditions of watercourses;<br />

• Identify the extent of river catchment areas;<br />

• Identify any existing catchment pressures (e.g. point source and diffuse pollution<br />

issues);<br />

• Identify any flood risks;<br />

• Establish the type and characteristics of soils and geology present;<br />

• Establish the hydrological regime; and<br />

• Identify any private drinking water abstractions and public water supplies within a 2 km<br />

radius.<br />

Establishing Sensitivity<br />

13.2.3 Once the above in<strong>for</strong>mation has been collected and assessed, it will be used to establish the<br />

sensitivity of the baseline environment. This will allow <strong>for</strong> key receptors to be identified and<br />

in<strong>for</strong>m the next stage of the adopted approach, the Impact Assessment.<br />

13.2.4 The sensitivity of the receiving environment, i.e. its ability to absorb the effect without<br />

perceptible change, is defined in Table 13.1, along with examples of characteristics that<br />

define receptor sensitivity.<br />

be assessed by taking into consideration the magnitude of effect predicted in relation to the<br />

sensitivity of the baseline.<br />

13.2.8 To determine the likely magnitude of effects, it is necessary to consider the timing, scale, size<br />

and duration of the potential activities. For the purposes of this assessment the magnitude<br />

criteria are defined as follows in Table 13.2.<br />

Table 13.2 Criteria <strong>for</strong> Defining Magnitude of Effect<br />

Magnitude Criteria Description and Example<br />

Large<br />

Results in loss of<br />

attribute.<br />

• Fundamental (long term or permanent) changes to<br />

geology, hydrology, water quality and hydrogeology;<br />

• Loss of designated Salmonid Fishery;<br />

• Loss of national level designated species/habitats;<br />

• Changes in WFD water quality status of river reach;<br />

• Loss flood storage/increased flood risk; and<br />

• Pollution of potable source of abstraction compared<br />

to pre-development conditions.<br />

Medium<br />

Affects integrity of<br />

attribute or partial loss of<br />

attribute.<br />

• Material but non-fundamental and short to medium<br />

term changes to the geology, hydrology, water<br />

quality and hydrogeology;<br />

• Loss in productivity of a fishery;<br />

• Contribution of a significant proportion of the<br />

discharges in the receiving water, but insignificant<br />

enough to change its water quality status; and<br />

• No increase in flood risk.<br />

Small<br />

Results in minor effect on<br />

attribute.<br />

• Detectable but non-material and transitory changes<br />

to the geology, hydrology, water quality and<br />

hydrogeology; and<br />

• No increase in flood risk.<br />

Negligible<br />

Results in an effect on<br />

attribute but of insufficient<br />

magnitude to affect the<br />

use/integrity.<br />

• No perceptible changes to the geology, hydrology,<br />

water quality and hydrogeology;<br />

• Discharges to watercourse but no reduction in<br />

quality, fishery productivity or biodiversity; and<br />

• No increase in flood risk.<br />

13.2.9 Once the magnitude of any potential effects has been assessed, the results can be compared<br />

with the sensitivity of the baseline environment and used to define the significance of the<br />

effect as outlined in Table 13.3.<br />

13.2.10 Potential effects are there<strong>for</strong>e assessed of being either of major, moderate, minor or<br />

negligible significance. Where the significance of the effects are determined to be major or<br />

moderate, it is considered that these represent significant effects that require mitigation.<br />

13.2.11 The results of the effect assessment are then used to identify what mitigation measures and<br />

monitoring schemes are required to ensure that effects are minimised and that action is taken<br />

or changes are made to the mitigation in place, if and when required.<br />

13.2.12 The aim of the mitigation measures is to avoid, reduce and, if possible, remedy the significant<br />

adverse effects identified. The mitigation measures identified here will be carried through to<br />

the Health, Safety and Environmental Management System (HSEMS), an outline structure of<br />

which is included at Appendix 4.4.<br />

Site Visit<br />

13.3.4 A walkover survey was undertaken in March 2012 to help determine the hydrological and<br />

geological characteristics of the proposed wind farm site and ground-truth the findings of the<br />

desk study. The survey allowed <strong>for</strong> a visual assessment of the surface water features, land<br />

use, hydrological regime and an increased understanding of the site topography, geology and<br />

soils. The weather conditions during the survey were overcast but dry and rainfall levels prior<br />

to the survey were considered to be typical of the estimated long-term annual average<br />

values.<br />

13.3.5 A watercourse crossing assessment was undertaken to confirm the locations at which the<br />

access tracks cross on-site streams, and any requirement to upgrade these crossing to<br />

facilitate wind farm construction. The watercourse crossing assessment has been included in<br />

Appendix 13.3 and includes the following in<strong>for</strong>mation:<br />

• Crossing survey maps;<br />

• Photographs across, upstream and downstream of the crossing point;<br />

• In<strong>for</strong>mation relating to hydromorphology of the stream crossing and riparian zone;<br />

• Outline design <strong>for</strong> proposed extension to existing drainage pipes;<br />

• The level of CAR authorisation likely to be required.<br />

Designated Areas<br />

13.3.6 There are no international designated conservation areas within or immediately adjacent to<br />

the site, however there are several national water quality designations within and adjacent to<br />

the site.<br />

13.3.7 The designated areas associated with the hydrology, hydrogeology and ground conditions<br />

within the site are shown in Table 13.7 below and illustrated on Figure 4.10 in Chapter 4:<br />

13.3.17 The southern and western slopes of Cairnoch Hill drain towards the Carron Valley Reservoir<br />

via a number of minor streams. The largest of these streams flows near the eastern boundary<br />

of the site and discharges into the reservoir in the vicinity of Kirk o’ Muir.<br />

13.3.18 Water levels within the reservoir set at a maximum elevation of 225 m AOD (Scottish Water<br />

2011).<br />

Endrick Water<br />

13.3.19 The north-western hill slopes of Cairnoch Hill drain towards a tributary of the Endrick Water.<br />

This is the only area within the development site outside the River Carron catchment. The<br />

Endrick Water flows in a westerly direction and discharges into Loch Lomond south of<br />

Balmaha.<br />

Flow Regime<br />

13.3.20 River levels and flows are monitored by SEPA along the River Carron and the Endrick Water.<br />

The nearest gauging stations are at Headswood (River Carron, NS 832 820) and Gaidrew<br />

(Endrick Water, NS 485 866) (Centre <strong>for</strong> Ecology and Hydrology n.d.). These stations are too<br />

far downstream to evaluate the flow regime at the development site. In the absence of river<br />

flow data near the development site, RPS has utilised data from the FEH to analyse the<br />

hydrological regime.<br />

13.3.21 The FEH Base Flow Index (BFI) indicates the proportion of runoff that derives from stored<br />

sources. For example, BFI of 0.1 might represent a relatively impermeable clay catchment<br />

whereas BFI of 0.99 might represent a highly permeable chalk catchment. BFI at the<br />

development site is approximately 0.34 (34%).<br />

13.3.22 The Standard Percentage Runoff (SPR) parameter, also provided by FEH, represents the<br />

typical percentage of precipitation that drains over the surface towards open watercourses<br />

during a storm. SPR at the development site ranges from between 39% and 50%.<br />

13.3.23 Overall the FEH parameters suggest that the development area, compared with other<br />

Scottish catchments, will respond quickly to rainfall events, the effect of which will be of<br />

increased significance when considering that rainfall is also relatively high within these<br />

catchments in comparison with others along the Scottish west coast.<br />

13.3.24 The low flow rates have been estimated <strong>for</strong> the unnamed watercourse discharging into the<br />

Carron Valley Reservoir near Kirk o’ Muir, as this location may be utilised as a surface water<br />

abstraction point <strong>for</strong> the proposed construction works, as shown in Figure 13.1. Table 13.8<br />

below shows the Mean Annual Flow (MAF) rate as well as the Q 95 low flow rate, being the<br />

flow rate (or smaller) occurring on average 5% of the time which corresponds to 18 days per<br />

year.<br />

Solid Geology<br />

13.3.25 The solid geology is fairly uni<strong>for</strong>m across the site, made up of extrusive igneous rocks<br />

(basaltic lavas) from the Clyde Plateau <strong>Vol</strong>canic Formation, part of the Strathclyde Group.<br />

Within the Stirling area, it is known <strong>for</strong> these deposits to exceed 500 m in depth. The are also<br />

two small igneous intrusions as shown in Figure 13.3.<br />

13.3.26 Several normal fault lines cross the site, running from west south west to east north east.<br />

13.3.27 Borrow pits will be located within the site as a source of construction material. The geological<br />

assessment of the suitability of the solid geology <strong>for</strong> such purposes is discussed in Appendix<br />

13.1. The size and location of the borrow pits is shown in Figure 13.3.<br />

Superficial Geology<br />

13.3.28 Superficial deposits across the site are predominantly Devensian till deposits, as shown in<br />

Figure 13.4, with further moraine deposits (sand, gravel and till) along the northern edge of<br />

the reservoir and western boundary of the site.<br />

13.3.29 The main central area of the site, around Cairnoch Hill, has limited superficial deposits with<br />

bedrock at or near the surface.<br />

13.3.30 Limited peat deposits are noted along the central and north western site boundary, and a<br />

very small area of alluvium around the mouth of an unnamed tributary flowing into the<br />

reservoir just northwest of Cairnoch.<br />

Soils and Peat<br />

13.3.31 The predominant soils within the site, summarised in Table 13.9, are noncalcareous humic<br />

gleys. These cover a similar spatial extent as the superficial till deposits noted within the site.<br />

These areas also contain some peaty gleys.<br />

13.3.32 The next predominant soil type within the site are Brown Forest Soils that correlate with the<br />

areas of bedrock at or near the surface within the central part of the site and to the western<br />

section of the site.<br />

13.3.33 The third soil type noted within the site is peaty podzols and humic iron podzols along the<br />

northern site boundary. The location of these soils correlates to the areas of peat shown in<br />

Figure 13.4.<br />

13.3.34 The presence of gley on site indicates that drainage is poor and saturation of the soils occurs<br />

with a high enough frequency to affect the soil profile. Gleys can be subdivided into two<br />

types: groundwater gleys and surface water gleys. Groundwater gleys occur in areas of low<br />

ground and basins where the water table is above the ground surface often enough to lead to<br />

gleying. Surface water gleys occur in areas where precipitation within the site cannot drain<br />

freely through the ground, which has a slowly permeable lower subsoil or substrate, leading<br />

to saturated soils or a "perched" water table.<br />

13.3.35 An initial peat assessment and depth survey was undertaken in August 2011 to in<strong>for</strong>m the<br />

initial wind farm layout. A subsequent survey was undertaken in April 2012 to identify in more<br />

detail peat depths at the locations of the proposed infrastructure to the north of the site,<br />

where the existence of peat was identified in the initial survey.<br />

13.3.36 There are limited peat deposits located within the north west boundary of the site. The<br />

deposits are highly disturbed by the presence of active commercial <strong>for</strong>estry, as well as the<br />

many drains that run throughout the areas of peat. Peat depths, as discussed in Appendix<br />

13.2, are highly erratic, with depths varying from 0.5 m to over 3.5 m over a distance of 20 m.<br />

13.3.37 As some of the proposed turbines and associated infrastructure are located adjacent to and,<br />

potentially, within areas of peat to the north west of the site, a Peat Stability Risk Assessment<br />

was undertaken to determine the risk of peat stability within this area. The report is provided<br />

in Appendix 13.2.<br />

Coal Mining<br />

13.3.38 The site is not located within over any coal measures, and there<strong>for</strong>e issues related to coal<br />

mining have not been considered further within this assessment.<br />

Hydrogeology<br />

13.3.39 The site is underlain by impermeable extrusive igneous strata. These rocks have very limited<br />

groundwater flow or storage capacity. SEPA’s Bedrock Aquifer map (SEPA, 2004) shows<br />

that the site is located on bedrock within which flow is dominated by fracture flow with a low<br />

productivity (F L).<br />

13.3.40 There may be more localised movement of groundwater through the superficial deposits due<br />

to the presence of sand and gravel within the glacial moraines and till, but these will be<br />

limited. The drift aquifer is mostly unclassified/ absent however the peat in the north and<br />

hummocky glacial deposits in the west are classified as having intergranular flow with low<br />

productivity.<br />

Carron Valley Wind Farm<br />

13.3.41 In accordance with the SNIFFER Guidance (2004), under which Class 1 is the least<br />

vulnerable and Class 5 is the most vulnerable, the majority of the site has a vulnerability<br />

classification of 4d (central and northern parts), with 4a-4c within the southern area of the<br />

site. There exists a small area of 5 in the south western part of the site and a small area in<br />

the vicinity of Turbine 10.<br />

13.3.42 This classification reflects the low permeability (fractured) and low productively of the igneous<br />

bedrock combined with the thin superficial deposits present across the majority of the site.<br />

13.3.43 As part of the ecological assessment of the site, (Chapter 11: Terrestrial Ecology), it was<br />

noted that the results of the National Vegetation Classification (NVC) survey indicated that<br />

there were several potential Groundwater Dependent Terrestrial Ecosystems, as defined by<br />

SEPA in their Landuse Planning System Guidance Note 4, 2011, within the site as shown in<br />

Figure 13.5. Having reviewed the location of these sites in relation to on-site observations as<br />

well as the abundant hydrology and limited hydrogeology of the site, it is considered likely<br />

that these habitats are fed by water from surface water in the <strong>for</strong>m of ponded water and<br />

overland flow, and are not fed by groundwater.<br />

Flood Risk<br />

13.3.44 In the context of planning and development, the government has defined a number of flood<br />

risk zones or levels as shown in Table 13.10 below (Scottish Government 2010). The table<br />

also shows government policy on whether development is acceptable in each zone.<br />

unless site specific conditions indicate otherwise. A<br />

flood risk assessment may be required at the<br />

upper end of the probability range (i.e. close to 0.5<br />

%) or where the nature of the development or local<br />

circumstances indicate heightened risk.<br />

> 0.5% Areas already built up may be suitable <strong>for</strong><br />

residential, institutional, commercial and industrial<br />

development provided flood prevention measures<br />

to the appropriate standard already exist, are<br />

under construction or are planned as part of a long<br />

term development strategy in a structure plan<br />

context. Land raising may be acceptable.<br />

> 0.5% Undeveloped and sparsely developed areas are<br />

generally not suitable <strong>for</strong> additional development,<br />

including residential, institutional, commercial and<br />

industrial development. Exceptions may arise if a<br />

location is essential <strong>for</strong> operational reasons, e.g.<br />

<strong>for</strong> navigation and water-based recreation uses,<br />

agriculture, transport or some utilities<br />

infrastructure, and an alternative lower risk location<br />

is not achievable. Land raising may be acceptable.<br />

13.3.45 The Indicative River and Coastal Flood Map <strong>for</strong> Scotland (Scottish Environment Protection<br />

Agency 2010) does not indicate any potential flood extent within the development site. This<br />

does not mean that there is no risk of flooding as the drainage areas of the rivers within the<br />

site are less than 3 km 2 . Such rivers are not included in SEPA’s flood map.<br />

13.3.46 Although the rivers within the site are small, a flood risk may still be present. However,<br />

flooding would likely be limited to areas directly adjacent to the river channels, due to the<br />

incised nature of the watercourse within the site. The steepness of some of the streams may,<br />

however, lead to fast flowing flood waters during periods of high rainfall.<br />

13.3.47 SEPA’s flood map indicates that no or very limited flooding from the Carron Valley Reservoir<br />

is expected. Water levels in the reservoir are controlled by a wide spillway at the eastern<br />

dam. Maximum water levels within the reservoir are 225 m AOD (Scottish Water 2011) which<br />

is likely to correspond to the spillway crest level or just above. The B818 road level near the<br />

development site is shown to be at 227 m AOD on Ordnance Survey 1:10,000 scale maps. It<br />

is there<strong>for</strong>e unlikely that the area or the access road near the development site is at risk of<br />

flooding from the reservoir.<br />

13.3.48 Some areas along the Endrick Water below the western Carron Valley Reservoir dam and<br />

some areas along the River Carron near the confluence with the Earl’s Burn are shown to be<br />

at risk of flooding. Generally, however, both rivers near the development site have only<br />

narrow floodplains.<br />

Overland Flooding<br />

13.3.49 Various degrees of overland flood risk exist in many areas in Scotland, including rural and<br />

urban areas. Overland flooding is caused by ponding of surface water, <strong>for</strong> example due to<br />

fully saturated soils, followed by flowing of water to lower lying areas. This flood risk can be<br />

highly localised in nature depending on the topography (including small details such as road<br />

kerbs etc) and the extent of natural or man-made drainage systems (including drainage<br />

ditches etc).<br />

13.3.50 Due to the steep slopes covering the majority of the site, along with impermeable soils, it is<br />

likely that overland flow will occur frequently, but due to the steep slopes characterising the<br />

site, it is unlikely that these overland flows would accumulate to the extent required <strong>for</strong><br />

flooding to occur.<br />

Groundwater Flooding<br />

13.3.51 Groundwater flooding results from water rising up from the underlying rocks or from springs.<br />

Groundwater flooding is most likely to occur in low-lying areas underlain by permeable<br />

bedrock.<br />

13.3.52 The restricted nature of groundwater flows within the bedrock beneath the site, the low<br />

permeability of the superficial geology (tills and gleys) and the gleyed nature of the soils is too<br />

restrictive to allow <strong>for</strong> any significant or widespread groundwater flooding within the site. The<br />

steep topography of the site also does not allow <strong>for</strong> extensive groundwater flooding.<br />

13.3.53 Very localised groundwater flooding may occur where there are sand and gravel deposits at<br />

or near the surface in areas where the topography is flat. Any observations of standing water<br />

within the site however are likely to be the result of rainfall runoff ponding in topographic low<br />

points underlain by impermeable soils.<br />

Artificial Drainage System Flooding<br />

13.3.54 Due to the presence of active commercial <strong>for</strong>estry throughout the majority of the site, there<br />

are numerous artificial networks draining water from the site.<br />

13.3.55 The specification, construction and placement of drainage between stands of trees and along<br />

<strong>for</strong>estry access tracks are set out in the document ‘Agreed Standard <strong>for</strong> the Design and<br />

Construction of the Carron Valley Wind Farm Access’, (FCS, October 2010) which specifies<br />

that all drainage systems should be designed to manage a 1 in 200 year flood event.<br />

13.3.56 Where systems are not maintained (e.g. build up of sediment or blockages are not removed),<br />

the effectiveness and capacity of such drainage systems may become compromised.<br />

Water Quality<br />

13.3.57 All major surface watercourses near the proposed wind farm are monitored by SEPA under<br />

the Water Framework Directive (WFD) <strong>for</strong> water quality and ecological status. The most<br />

recent classifications based on data collected in 2008 is shown in Table 13.11 below.<br />

Alexandria Bedrock groundwater unit which is located 4 km west of the proposed site.<br />

Water Resources<br />

13.3.60 In<strong>for</strong>mation provided by Stirling Council indicated that there were no private water supplies<br />

located within the catchments draining the proposed development or immediately adjacent to<br />

the site (Figure 13.1).<br />

13.3.61 Scottish Water provided detailed drawings showing the location of their water supply and<br />

sewerage infrastructure near the development site (Scottish Water 2011). Raw water<br />

distribution pipes are shown at both dams of the Carron Valley Reservoir. Other pipe<br />

infrastructure near the reservoir includes water distribution mains. None of the infrastructure<br />

is located within the development site. The location of the pipe network is shown in<br />

Figure 13.2.<br />

13.3.62 Not shown on Scottish Water’s drawings are the aqueducts used to transfer water from the<br />

River Endrick to Carron Valley Reservoir and from the Earl’s Burn to Buckieburn Reservoir.<br />

The alignments of these aqueducts have been estimated based on the known locations of<br />

intakes and outlets and are also shown in Figure 13.2.<br />

Controlled Activities Regulations<br />

13.3.63 Details of activities covered by the Water Environment (Controlled Activities)(Scotland)<br />

Regulations 2011, present within the vicinity of the site were requested from SEPA. This data<br />

excluded details of Scottish Water licences, due to security concerns.<br />

13.3.64 The locations of these activities are shown in Figure 13.2 and detailed in Table 13.13 below.<br />

13.3.72 The site underlain by a relatively impermeable solid geology, where groundwater will be<br />

restricted to fracture flow. Will little or no significant soils covering the majority of the site, the<br />

groundwater vulnerability will be high. Where there are superficial deposits, the majority of<br />

these are of low permeability, and are there<strong>for</strong>e likely to result in rainfall runoff as the majority<br />

of the site is too steep to allow <strong>for</strong> ponding.<br />

13.3.73 The large number of small burns, artificial drainage systems, relatively high annual rainfall<br />

and low permeable geology result in a site that has a quick response to rainfall events.<br />

There<strong>for</strong>e it is reasonable to expect quick changes to flows in watercourse and drainage<br />

channels as well as significant volumes of overland flow during heavy rainfall events.<br />

13.4 Topic Specific Design Evolution<br />

13.4.1 During the design evolution process, a buffer of 50 m was established around all of the<br />

watercourses identified on the 1:25,000 OS map of the site, and the number of instances of<br />

water crossings was minimised as far as possible.<br />

13.4.2 The results of initial peat probing were used in order to locate turbines away from deep peat,<br />

or from peat altogether.<br />

13.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

13.5.1 This section describes the potential effects on hydrology, geology and hydrogeology that<br />

could arise in the absence of mitigation during the following phases of the proposed wind<br />

farm:<br />

• Construction;<br />

• Operation;<br />

• Decommissioning.<br />

13.5.2 Due to the nature of the site and the nature of the proposed development, a number of the<br />

predicted construction and decommissioning effects are predicted to be similar.<br />

13.5.3 The assessment of potential effects has been carried out <strong>for</strong> the proposals without any<br />

mitigation measures in place as well as considering a range of mitigation measures. In each<br />

case the potential magnitude is assessed.<br />

Construction<br />

13.5.4 The most significant phase in terms of the potential effects is the construction period. This<br />

section identifies the effects that are likely to occur in the hydrological, hydrogeological and<br />

geological environment during construction of the proposed wind farm.<br />

Hydrology<br />

Effects on Surface Runoff Characteristics<br />

13.5.5 Localised increases in the rate and volume of surface runoff could potentially be caused by<br />

excavations, keyhole felling, exposure of bare soils, compaction of soils and poor design of<br />

site drainage. As well as increasing the risk of downstream flooding, this could also alter the<br />

water quality and hydrological regime of the site.<br />

Carron Valley Wind Farm<br />

13.5.6 Track and turbine foundation construction works have the potential to alter the drainage<br />

mechanisms within the site, <strong>for</strong> example through:<br />

• diversion of surface runoff away from natural drainage routes;<br />

• collection of runoff and rainfall within excavations;<br />

• reduction of rainfall interception in areas felled to accommodate construction;<br />

• reduction or increase in infiltration or percolation to groundwater;<br />

• ponding of surface water through obstructions of flow paths, etc.<br />

13.5.7 Compaction of soils may be caused by the movements of construction traffic and machinery.<br />

This would reduce the soil permeability and there<strong>for</strong>e rainfall infiltration, and potentially lead<br />

to higher catchment runoff rates, in particular during high rainfall.<br />

13.5.8 Although tracks and hard standing areas will be constructed using granular material, surfaces<br />

are likely to become compacted which is likely to limit infiltration through the track and hard<br />

standing area bases. The total surface area that may be compacted has been calculated and<br />

compared with the various catchments in which the infrastructure is located, as presented in<br />

Table 13.15 below.<br />

13.5.9 The potential effects on runoff and infiltration are considered to have a medium magnitude,<br />

and the sensitivity of the local tributaries affected is considered to be low, resulting in a slight<br />

significance without mitigation.<br />

Effects on River Flows and Flooding<br />

13.5.10 Inadequately designed watercourse crossings could restrict watercourses flow regimes within<br />

the site. This may lead to increased water levels upstream and result in localised increases<br />

of flood risk.<br />

13.5.11 Additionally, poorly designed crossing structures could lead to localised erosion and<br />

sedimentation. Not only could this have an effect on the stability of the structure, but this<br />

could also have a detrimental effect on water quality caused by a higher than normal<br />

sediment load.<br />

13.5.12 Sudden changes in bed levels or flow regimes (<strong>for</strong> example hydraulic jumps) could potentially<br />

occur at in-bank structures if not adequately designed. This could lead to the impediment of<br />

fish migration.<br />

13.5.13 During the construction phase, approximately 30 m 3 of water per day would be required <strong>for</strong><br />

the concrete batching and associated activities such as plant washing. This water would be<br />

abstracted from the unnamed tributary near Kirk O’Muir. The required volume of water<br />

corresponds to approximately 0.6 % of the average flow and 5.3 % of the low flow rate in the<br />

stream. Note that land upstream from the proposed abstraction, including any peat bog, is<br />

not affected by the abstraction as the water table will not be lowered.<br />

13.5.14 Effects on river flows and flooding are considered to be of small magnitude and as the fluvial<br />

system within the site is of low sensitivity, this results in an effect that is slight to negligible<br />

without mitigation.<br />

Effects on Peat<br />

13.5.15 Disturbance of peat deposits might occur during construction activities on the site which could<br />

result in loss of carbon storage, generate waste peat materials from excavations and may<br />

affect the hydrology of peat.<br />

13.5.16 The only area of peat that will be affected by the construction activities are located within the<br />

Endrick Water catchment near to Turbine 1 and 2..<br />

13.5.17 A Peat Stability Risk Assessment has been completed (see Appendix 13.2). This concludes<br />

that the site has acceptable factors of safety and a medium or less risk in relation to peat<br />

stability. This is there<strong>for</strong>e considered to be of small magnitude and slight significance.<br />

13.5.18 A detailed map of peat depth <strong>for</strong> deposits of peat located within the site is included in<br />

Figure TA13.2.5 in Appendix 13.2. The peat within the site is sparse and fragmented. The<br />

total area with peat deposits more than 0.5 m deep is approximately 14.75 ha which equates<br />

to 65% of the total area surveyed within the north west of the site.<br />

13.5.19 Where the tracks or foundations are near deep peat, the construction may locally lower the<br />

groundwater table within peat deposits. In the long-term this could then lead to degrading of<br />

the bog and a reduction in peat depth. Additionally, tracks intersecting with overland or<br />

groundwater flow paths, could lead to increased drainage or lead to blockage of flows. Note<br />

that only a short section of the Turbine 2 access is near deep peat.<br />

13.5.20 The potential effect on the hydrological regime of peat is considered to be of small to medium<br />

magnitude and slight significance to negligible.<br />

Erosion and Sedimentation<br />

13.5.21 Changes in natural drainage patterns due to runoff from exposed soil, dewatering, felling,<br />

stripping of vegetation and topsoils may lead to the erosion and transport of sediment into<br />

watercourses. Increased flow rates due to changes in site drainage can also lead to<br />

increased erosion of watercourse bed and banks. Sedimentation of watercourses can have a<br />

detrimental effect on flood storage capacity and water quality.<br />

13.5.22 Where sediment-laden waters are allowed to pond in areas where bedrock is at or near the<br />

surface, including borrow pits, there is a risk that the contaminated waters may flow through<br />

fractures in the bedrock, into local groundwater and into local watercourses.<br />

13.5.23 Sediment can settle out in slower moving stretches of a watercourse, with the potential to<br />

smother gravels used <strong>for</strong> salmonid spawning and hatching, whilst deposits of significant<br />

quantities of sediment can alter river morphology. Sediment can also have effects on the<br />

health of aquatic fauna by interfering with respiration and increasing stress levels. An<br />

assessment of the effects on aquatic fauna is presented in Chapter 11: Terrestrial Ecology.<br />

13.5.24 The effects from erosion and sedimentation on the surface water bodies downstream of the<br />

site, which have high receptor sensitivity, are considered to be of a medium to large<br />

magnitude and moderate to very substantial significance without mitigation.<br />

Water Quality<br />

13.5.25 A number of chemicals may be stored and used on-site during the construction of the<br />

proposed wind farm. These include unset concrete, concrete additives, fuel and oil. These<br />

pollutants may adversely affect the water quality of the receiving surface water and<br />

groundwater environment.<br />

13.5.26 Spillages of concrete may occur during concrete pumping operations into turbine bases,<br />

which may runoff into surface watercourses or seep into groundwaters. Concrete is highly<br />

corrosive and can cause pH changes in watercourses. This can have severe or fatal<br />

consequences on freshwater ecology. An assessment of the effects of changes to water<br />

quality on aquatic fauna is presented in Chapter 11: Terrestrial Ecology.<br />

13.5.27 Contamination of surface water may also occur as a result of spillages from routine plant<br />

maintenance, improper storage and accidental spillages.<br />

13.5.28 Should an unmitigated pollution incident occur, there is a potential <strong>for</strong> periods of heavy rain to<br />

increase the volume of surface water runoff with pollutant Ioads such as oils and fuels from<br />

hardstandings and unset concrete from turbine foundations.<br />

13.5.29 Due to the potential use of the chemicals adjacent to watercourses on-site, the potential<br />

effects associated with chemical pollution on the water quality of the high sensitivity surface<br />

waters downstream of the site, any releases of chemicals are likely to have a large<br />

magnitude and there<strong>for</strong>e have substantial to very substantial effect without mitigation.<br />

Soils<br />

13.5.30 During construction, some excavations may require temporary sub-surface water controls,<br />

such as physical cut-offs or dewatering. Cut-off drains divert flows away from construction<br />

activities, while dewatering temporarily lowers the water table in the vicinity of the excavation.<br />

13.5.31 Changes to soil flow patterns can be caused by the movement of construction traffic that may<br />

lead to compaction of the soil, reducing soil permeability and rainfall infiltration.<br />

13.5.32 The effects of construction on drainage patterns on the low sensitivity soils are considered to<br />

be of a medium magnitude and slight significance.<br />

Superficial Deposits<br />

13.5.33 The excavation of foundations can have adverse effects on the superficial deposits (glacial till<br />

etc). The magnitude of this effect is considered to be small and the sensitivity of superficial<br />

deposits is low, and there<strong>for</strong>e the predicted effects would be slight/negligible.<br />

Geology<br />

13.5.34 The excavation of deep foundations <strong>for</strong> turbines and quarrying within borrow pits may effect<br />

on the bedrock and have adverse effects on the local geological resource.<br />

13.5.35 The site is not within a geologically designated area and the sensitivity of bedrock within the<br />

proposed development area is there<strong>for</strong>e considered to be low. As such, the magnitude of<br />

effect is considered to be small and the effect slight/negligible.<br />

13.5.36 As it is proposed that material <strong>for</strong> construction of the site tracks and production of concrete is<br />

sourced from within the site from, three Borrow Pits will be created. The proposed location of<br />

the Borrow Pits is shown in Figure 1.2. The geological implications of this proposal have been<br />

assessed in Appendix 13.1.<br />

Hydrogeology<br />

Modifications to Hydrogeological Regime<br />

13.5.37 Any dewatering required <strong>for</strong> turbine foundation excavations and borrow pits, as well as other<br />

construction activities, is likely to have a minimal effect due to the low permeability of the<br />

bedrock and superficial deposits. However, deep excavations such as those needed <strong>for</strong> the<br />

turbine bases and borrow pits are likely to disrupt any shallow groundwater systems within<br />

superficial deposits and upper bedrock. Temporary groundwater controls such as dewatering<br />

or physical cut-offs may be required to prevent the excavations filling with water, which would<br />

be likely to result in the lowering of groundwater levels in the immediate vicinity of the<br />

excavation. Cable trenches can also provide preferential flow pathways <strong>for</strong> groundwater,<br />

especially if cut to the soil/drift bedrock interface.<br />

13.5.38 The magnitude of these potential effects on the groundwater environment at the proposed<br />

site is considered to be medium and the sensitivity of the groundwater is considered to be<br />

high. The significance of this effect prior to mitigation is there<strong>for</strong>e substantial - moderate.<br />

Chemical Pollution<br />

13.5.39 The leaching of hydrocarbons, chemicals, trans<strong>for</strong>mer oils and fuel from any spills during<br />

construction present a potential source of contamination to underlying groundwater. The<br />

glacial till and moraine deposits present within the site are expected to provide protection to<br />

the limited groundwater in the bedrock where present and would not be removed as part of<br />

the construction works. The magnitude of this effect is there<strong>for</strong>e considered to be medium<br />

and the sensitivity of the groundwater is considered to be high. The significance of this effect<br />

prior to mitigation is there<strong>for</strong>e substantial - moderate.<br />

Private Water Supplies<br />

13.5.40 Potential effects on private water supplies include the infiltration or runoff of contaminants<br />

from any releases of chemicals stored on site with the potential to affect the quality of surface<br />

waters from which the supplies abstract.<br />

13.5.41 Activities such as dewatering excavations may also impact supplies if undertaken within<br />

catchment areas of local supplies as private water supplies are also very susceptible to local<br />

changes in flow regimes, which may be small on a catchment scale, but may be<br />

comparatively large in relation to the quantities abstracted <strong>for</strong> supply. These effects may be<br />

long term.<br />

13.5.42 The baseline assessment indicates that there no private water supplies within the catchments<br />

draining the site, though there are several in the surrounding area, as shown in Figure 13.1.<br />

There<strong>for</strong>e the magnitude of any effect is considered to be negligible and sensitivity of private<br />

water supplies is considered to be negligible. This effect is there<strong>for</strong>e negligible.<br />

Public Water Supplies and Abstractions<br />

13.5.43 The Carron Valley Reservoir is used <strong>for</strong> public water supplies and the associated<br />

infrastructure adjacent to the site is shown in Figure 13.2. The reservoir is fed by water from<br />

the headwaters of the River Carron, with the potential to top up reservoir levels from the<br />

Endrick Water.<br />

13.5.44 Potential effects on public water supplies include the infiltration or runoff of contaminants from<br />

any releases of chemicals stored on site with the potential to affect the quality of surface<br />

waters from which the supplies abstract, and effects on available water resources due to<br />

alterations to flow.<br />

13.5.45 Any release of contaminants that reaches the Carron Valley Reservoir or Endrick Water<br />

would be impacting upon a public water supply. The magnitude of the effect would be<br />

dependent on the type and extent of the contamination. There<strong>for</strong>e the magnitude of this<br />

effect is considered to be medium to large and the sensitivity of the receptors is high. The<br />

significance of this prior to mitigation is there<strong>for</strong>e moderate to very substantial.<br />

13.5.46 In terms of water resource, as a source of public water supplies the reservoir would only be<br />

impacted by large abstractions or diversions of flow which are not proposed in this instance.<br />

There<strong>for</strong>e, the magnitude of the potential effect on public water supplies is considered to be<br />

negligible and whilst the sensitivity of the receptor is high this nonetheless results in a<br />

predicted effect that is negligible.<br />

Operation<br />

13.5.47 The following section identifies the potential effects that could occur on the hydrological,<br />

hydrogeological and geological environment during the operation of the proposed wind farm.<br />

Hydrology<br />

Effects on Surface Runoff Characteristics<br />

13.5.48 The proposed infrastructure, including turbine foundations and access tracks, could<br />

potentially affect the surface runoff and drainage characteristics in nearby areas. The<br />

presence of impermeable surfaces could potentially lead to a quicker catchment response<br />

with increased peak runoff rates. However, given the very small percentage of area used <strong>for</strong><br />

infrastructure, this is unlikely to be significant. Additionally, the proposed infrastructure is<br />

sparse surrounded by large areas of undisturbed fields.<br />

13.5.49 Access tracks have the potential to intercept surface runoff and alter drainage paths. For<br />

example, when tracks are constructed along hill slopes, runoff from the upslope gradient may<br />

be intercepted and could cause flooding of the track in the absence of mitigation measures.<br />

Tracks could potentially become preferential drainage paths where runoff is channelled away<br />

from natural flow paths. This could lead to substantial overland flows and could cause<br />

erosion and a reduction in surface water infiltration.<br />

13.5.50 The <strong>for</strong>estry within the proposed wind farm is currently drained through a large number of<br />

artificial drains. It is there<strong>for</strong>e expected that any effect on runoff and drainage due to the<br />

proposed access tracks is not as significant as it would be if the drainage within the site was<br />

not already altered.<br />

13.5.51 The potential effect on runoff and infiltration on the local low sensitivity fluvial system is<br />

considered to have a medium magnitude and there<strong>for</strong>e a slight significance without<br />

mitigation.<br />

Carron Valley Wind Farm<br />

Effects on River Flows and Flooding<br />

13.5.52 Effects on river flows and flood risk are similar as during the construction phase. This is<br />

considered to have a small magnitude and low sensitivity, resulting in negligible to slight<br />

significance without mitigation.<br />

Effects on Peat Hydrological Regime<br />

13.5.53 Effects on the hydrological regime of peat are similar as during the construction phase. This<br />

is considered to have a small to medium magnitude and peat is assessed as being of low<br />

sensitivity, resulting in an effect of slight significance to negligible without mitigation.<br />

Erosion and Sedimentation<br />

13.5.54 Levels of erosion and sedimentation are likely to be much lower than during the construction<br />

phase as there are no excavations or bare exposed ground, following post construction<br />

restoration. Some erosion and sedimentation is still possible on the site tracks,<br />

hardstandings and drainage ditches as a result of scouring during extreme rainfall events.<br />

Similarly there could be some minor erosion and sedimentation around new and upgraded<br />

stream crossings as watercourses find a new equilibrium. This can have a secondary<br />

detrimental effect on the ecology of aquatic plants, fish, and invertebrates, which are<br />

discussed further in Chapter 11: Terrestrial Ecology. These effects on the high sensitivity on<br />

the high sensitivity downstream surface water bodies are considered to be of small<br />

magnitude and moderate to slight significance without mitigation.<br />

Water Quality<br />

13.5.55 The potential risk of pollution is substantially lower during the operational phase because of<br />

the decreased levels of activity. The majority of potential pollutants will have been removed<br />

when construction is complete. However, lubricants <strong>for</strong> turbine gearboxes, hydraulic oils and<br />

the potential <strong>for</strong> possible fuel leaks from maintenance vehicles will remain.<br />

13.5.56 Borrow Pit C will also continue to be used during the operational phase, as a store <strong>for</strong><br />

materials to be used <strong>for</strong> site maintenance (e.g. tracks). Though no quarrying will take place,<br />

the materials stored in the borrow pit have the potential to release sediment into rainfall runoff<br />

from the area. Maintenance activities themselves will also have the potential to result in the<br />

release of sediment into the water environment.<br />

13.5.57 The effects on the downstream high sensitivity water bodies arising from these activities are<br />

considered to be of small magnitude and moderate to slight significance without mitigation.<br />

Soils<br />

13.5.58 The presence of the concrete turbine foundations, tracks and cable trenches may cause<br />

obstructions <strong>for</strong> natural drainage and flow patterns within the local soils.<br />

13.5.59 The potential effects of these changes during the operation phase on the low sensitivity soils<br />

are considered to be of small magnitude and slight significance/negligible.<br />

Superficial Deposits<br />

13.5.60 No excavations of superficial deposits will occur during the operational phase. There<strong>for</strong>e, the<br />

magnitude of effect on superficial deposits will be negligible and the sensitivity is low,<br />

resulting in effects that will not be significant.<br />

Carron Valley Wind Farm<br />

Geology<br />

13.5.61 No excavations of bedrock will occur during the operational phase. There<strong>for</strong>e, the magnitude<br />

of effect on bedrock will be negligible and the sensitivity is low, resulting in effects that will not<br />

be significant.<br />

Hydrogeology<br />

Modification to Hydrogeological Regime<br />

13.5.62 Cut tracks and their drainage may alter the water table within superficial deposits and the<br />

upper bedrock aquifer. Backfilled cable trenches may provide preferential flow pathways <strong>for</strong><br />

groundwater. The above effects are considered to be of medium magnitude and the<br />

sensitivity of groundwater is considered to be high, resulting in an effect of substantial to<br />

moderate significance prior to the implementation of mitigation.<br />

Chemical Pollution<br />

13.5.63 During the operational phase of the proposed wind farm there will be considerably less onsite<br />

activity than during construction however, leaching of contaminants from chemicals<br />

stored on site and maintenance activities would still be a source of pollution to underlying<br />

groundwater. The glacial till is expected to provide protection to the groundwater in the<br />

bedrock where it is present but there are areas of the site where it is absent. The above<br />

effects are considered to be of medium magnitude and the sensitivity of groundwater is<br />

considered to be high, resulting in an effect of substantial to moderate significance prior to<br />

the implementation of mitigation.<br />

Private Water Supplies<br />

13.5.64 No private water supplies are predicted to be affected during the operation of the wind farm<br />

as there are no underground works or further disturbances to runoff or groundwater. The<br />

magnitude is there<strong>for</strong>e negligible and the sensitivity is negligible, resulting in a effect that is<br />

considered to be negligible.<br />

Public Water Supplies<br />

13.5.65 Public water are not predicted to be affected during the operation of the wind farm as there<br />

are no underground works or further disturbances to runoff or groundwater.<br />

13.5.66 Potential effects on the quality of public water supplies from infiltration or runoff of<br />

contaminants from any releases of chemicals stored on site will remain a risk, albeit with a<br />

much reduced likelihood of occurrence compared to the construction phase.<br />

13.5.67 Any release of contaminants that reaches the Carron Valley Reservoir or Endrick Water<br />

would be impacting upon a public water supply. As the magnitude of the effect would be<br />

dependent on the type and extent of the contamination, the likely magnitude of this effect<br />

during the operational phase is considered to be small. As the sensitivity of the receptors is<br />

high, the significance of this effect prior to mitigation is there<strong>for</strong>e moderate to slight.<br />

13.5.68 Small abstractions may still continue to supply the welfare facilities on site. These quantities<br />

will be much reduced compare to the abstracted quantities required <strong>for</strong> the construction<br />

phase. The magnitude of the effect is considered negligible and though the sensitivity is<br />

considered high, the resulting effect is considered to be negligible.<br />

Decommissioning<br />

Hydrology<br />

Effects on Surface Runoff Characteristics<br />

13.5.69 The potential effects of the decommissioning works on surface runoff within the local fluvial<br />

system are similar as during the construction phase although of a smaller magnitude. During<br />

the decommissioning, the turbine and track foundations are left in place and top-soils will be<br />

restored above the foundations. There is there<strong>for</strong>e a smaller risk of changes to runoff flow<br />

paths and drainage in general. As the receptor is of low sensitivity and the effect is<br />

considered to have a small magnitude, the effect will not be significant.<br />

Effects on River Flows and Flooding<br />

13.5.70 The decommissioning of the proposed wind farm is not likely to have any adverse effect on<br />

river flows and flooding on the site’s fluvial systems. As the receptor is of low sensitivity, the<br />

effect is there<strong>for</strong>e considered to have negligible magnitude and not be significant.<br />

Effects on Peat<br />

13.5.71 Potential effects of the decommissioning phase are expected to be similar in nature but to a<br />

lesser extent than those of the construction phase, and have not been assessed further.<br />

Erosion and Sedimentation<br />

13.5.72 Erosion or sedimentation may occur as a result of general earth works as part of the<br />

decommissioning and landscaping works. Considering the high sensitivity surface water<br />

bodies downstream of the site, and that the magnitude of this effect is likely to be small (less<br />

than the construction phase) the significance of the effect will be of moderate to slight<br />

significance without mitigation.<br />

Water Quality<br />

13.5.73 The effect on water quality and the potential <strong>for</strong> chemical pollution of the sensitive surface<br />

water bodies down stream of the site is similar as those arising during the construction phase<br />

and is considered to have a large magnitude and substantial to very substantial significance<br />

without mitigation.<br />

Soils, Superficial Deposits, Geology and Hydrogeology<br />

13.5.74 The effects are expected to be the same, and no worse, than those of the construction<br />

phase.<br />

Water Resources<br />

Private Water Supplies<br />

13.5.75 Existing private water supplies are unaffected during the decommissioning of the wind farm<br />

and are not considered any further in this assessment. Any potential effect on new water<br />

supplies developed during the life-time of the wind farm will need to be assessed at the<br />

appropriate time prior to decommissioning.<br />

Public Water Supplies<br />

13.5.76 The effect on water quality and the potential <strong>for</strong> chemical pollution of surface water during<br />

decommissioning is similar to that of the construction phase. As such, it is considered that<br />

sources of public water supply, from a release of contamination would be of large magnitude<br />

and substantial to very substantial significance without mitigation.<br />

13.5.77 In terms of water resource, as a source of public water supplies the reservoir would only be<br />

impacted by large abstractions or diversions of flow which are not currently considered likely<br />

to occur during decommissioning. There<strong>for</strong>e, the magnitude of the potential effect on public<br />

water supplies is considered to be negligible and whilst the sensitivity of the receptor is high<br />

this nonetheless results in a predicted effect that is negligible.<br />

13.6 Mitigation and Enhancement Measures<br />

13.6.1 A number of design and management measures during the construction, operation and<br />

decommissioning of the proposed wind farm have been identified below. Mitigation<br />

measures are in accordance with the Good Practice During Windfarm Construction<br />

publication, issued jointly by Scottish <strong>Renewables</strong>, SNH, SEPA and Forest Commission<br />

Scotland in October 2010. Reference has also been made to SEPA’s Regulatory Position<br />

<strong>Statement</strong> <strong>for</strong> Developments on Peat (9 February 2010) and the relevant sections of the FCS<br />

Civil Standard guidance document.<br />

13.6.2 These measures are designed to reduce the significance of the effects predicted above, as<br />

summarised in Table 13.16.<br />

Site Pollution Control<br />

13.6.3 A Health, Safety and Environmental Management System (HSEMS), including pollution<br />

prevention measures, specifically aimed at the water environment, and construction method<br />

statements, will be in place during construction, operation and decommissioning. An outline<br />

structure of the document is presented in Appendix 4.4. The HSEMS will include the<br />

mitigation measures to be implemented to prevent or minimise effects on the surface and<br />

groundwater environment, and will also include a bespoke Incident Response Plan.<br />

13.6.4 The timing of the works will be planned to avoid construction of tracks and other potentially<br />

polluting activities during periods of high rainfall as far as reasonably practicable.<br />

13.6.5 The HSEMS will address the following issues:<br />

• Storage – all equipment, materials and chemicals will be stored in designated locations<br />

at an appropriate distance from watercourses. Chemical, fuel and oil stores will be<br />

sited on impervious bases within a secured bund in accordance with relevant guidance<br />

and best practice.<br />

• Vehicles and Refuelling – standing machinery will have drip trays placed underneath to<br />

prevent oil and fuel leaks causing pollution. Drip trays will have minimum capacity of<br />

110% of the fuel tank. Where practicable, refuelling of vehicles and machinery will be<br />

carried out in one or potentially two designated areas, on an impermeable surface, and<br />

well away from any watercourse. Drip trays will also be used during refuelling and spill<br />

kits will be stored in vehicles on site, at designated refuelling areas and where<br />

chemicals are stored. Site staff will be training in their use.<br />

• Maintenance – where vehicles or plant require maintenance, this will be undertaken in<br />

a designated area within the construction compound where reasonably practicable,<br />

unless vehicles have broken down necessitating maintenance at the point of<br />

breakdown, where special precautions will be taken.<br />

• Welfare Facilities – on-site welfare facilities will be adequately designed and<br />

maintained to ensure that all wastewater and sewage is disposed of appropriately.<br />

This may take the <strong>for</strong>m of an on-site septic tank with soakaway, or offsite disposal<br />

depending on the suitability of the site <strong>for</strong> a soakaway and prior agreement with SEPA.<br />

• Cement and Concrete – fresh concrete and cement are very alkaline and corrosive,<br />

and can be lethal to aquatic life. The use of wet concrete in and around watercourses<br />

will be avoided or, where essential, carefully controlled by provision of an agreed<br />

construction method statement prior to construction.<br />

• Contingency Plans – will ensure that emergency equipment will be available on-site i.e.<br />

spill kits and absorbent materials, addition pumps, in<strong>for</strong>mation on where and from<br />

whom to seek advice, and who should be in<strong>for</strong>med in the event of a pollution incident.<br />

• Inspections – All mitigation measures put in place, e.g. silt traps and sediment<br />

settlement tanks, will be inspected regularly and suitably maintained to ensure they<br />

remain fully operational and effective. Where failures or shortfalls within mitigation<br />

measures are noted, these will be recorded, suitable action identified and undertaken<br />

within a suitable timeframe.<br />

Waste Management<br />

13.6.6 The production of waste will be minimised throughout the works, including wastes from peat<br />

and this has been taken into account in the design process to avoid where possible areas of<br />

deeper peat. Where waste is generated, this will be reused and recycled where possible.<br />

13.6.7 A Site Waste Management Plan (SWMP) will be produced to address the management of<br />

waste streams. The SWMP will address the following issues:<br />

• Waste Minimisation;<br />

• Separation of Waste at Source;<br />

• Appropriate Storage and Disposal of Waste taking account of stability and pollution<br />

prevention;<br />

• Management of peat, Superficial Deposits and Bedrock;<br />

• Re-use of peat where possible on site;<br />

• Management of Waste Oils;<br />

• Recommendations <strong>for</strong> Inspection and Maintenance.<br />

13.6.8 Consultation with SEPA will be required <strong>for</strong> any intended re-use of peat on the site.<br />

Environmental Monitoring<br />

13.6.9 A groundwater and surface water monitoring programme will be implemented to obtain<br />

baseline data, as well as data during construction works. The scope will be agreed with<br />

SEPA and Stirling Council prior to implementation.<br />

Surface Water<br />

13.6.10 A surface water monitoring network will be established a minimum of six months prior to<br />

construction works. The monitoring network will consist of control monitoring points upstream<br />

of construction works as well as monitoring points downstream of the works. The network will<br />

include monitoring points downstream of the borrow pits.<br />

Carron Valley Wind Farm<br />

13.6.11 In addition to surface water monitoring, regular visual inspection of surface water<br />

management features such as drainage pipes and receiving watercourses will be carried out<br />

in order to establish whether there are increased levels of suspended sediment, erosion or<br />

deposition. It is likely that there will be an ongoing need to maintain these structures, <strong>for</strong><br />

example by the removal of debris, to ensure they continue to function as designed.<br />

13.6.12 Regular visual inspection of watercourses will also be required during construction and<br />

decommissioning stages, particularly during periods of high rainfall but also during low flow<br />

conditions, in order to establish that levels of suspended solids have not been significantly<br />

increased by on-site activities.<br />

13.6.13 Monitoring will also be required as a condition of any discharge consents, abstraction<br />

licences or other environmental regulations.<br />

13.6.14 A preliminary design <strong>for</strong> the water monitoring regime recommended <strong>for</strong> the site is provided<br />

within Appendix 13.4.<br />

Monitoring Ground Movement<br />

13.6.15 As the access tracks are being constructed, the appearance of the track and surrounding<br />

land will be monitored <strong>for</strong> increased rate of sinking or tilting or a rise in water levels.<br />

13.6.16 A line of surveyed and levelled pegs and visual monitoring is an acceptable method of<br />

monitoring movement adjacent to roads.<br />

13.6.17 During and immediately after periods of heavy rainfall, earthmoving activities will be reviewed<br />

with temporary restrictions where necessary.<br />

Drainage<br />

13.6.18 The implementation of Sustainable Drainage Systems (SuDS) as opposed to conventional<br />

drainage systems on the proposed wind farm will provide several benefits by:<br />

• Reducing peak flows to watercourses and potentially reducing risk of flooding<br />

downstream;<br />

• Reducing the volumes and frequency of water flowing directly to watercourses;<br />

• Improving water quality by removing pollutants;<br />

• Reducing potable water demand through rainwater harvesting;<br />

• Replicating natural drainage patterns, including the recharge of groundwater so that<br />

local base flows are maintained.<br />

13.6.19 Where appropriate, SuDS principles have been incorporated into the water management<br />

methods discussed in the following sections.<br />

13.6.20 Where there is a high risk of oil contamination identified by the appointed construction<br />

contractor, and subsequently by the site operator, it may be appropriate to integrate an oil<br />

separator into any SuDS measures. The implementation of the type of SuDS measures will<br />

be dependent upon detailed site and hydrological investigations. Key runoff characteristics<br />

and drainage areas are shown in Figure 13.1.<br />

Private Water Supplies<br />

13.6.21 There are no private water supplies recorded within the catchments draining the proposed<br />

development, and there<strong>for</strong>e no mitigation measures are proposed.<br />

Carron Valley Wind Farm<br />

Abstractions<br />

13.6.22 A surface water abstraction will be required <strong>for</strong> the concrete batching and washing of plant. It<br />

is estimated that approximately 30 m 3 of water will be required per day. To minimise<br />

downstream effects during periods of low flows, a proportion of water will be left in the stream<br />

<strong>for</strong> water quality purposes, fish and other fauna. On-site water storage facilities will also be<br />

provided to create a water supply buffer <strong>for</strong> periods of high demand or prolonged low flows.<br />

13.6.23 If more than 50 m 3 /day is required to be abstracted, an application will be made <strong>for</strong> a “simple<br />

licence” under the Controlled Activities Regulations (CAR). Full details on the abstraction<br />

rates, flow rates, etc will be provided as part of the licence application. If the abstraction<br />

requires less than 50 m 3 /day “general binding rules” under the CAR will be followed.<br />

Geotechnical Design<br />

13.6.24 Detailed geotechnical design will be undertaken <strong>for</strong> each turbine location, access track, hard<br />

standing areas and the construction compound. This will be based on the location-specific<br />

mechanical characteristics of the ground conditions and the morphology of the underlying<br />

strata (i.e. superficial deposits or bedrock). Further targeted ground investigation will<br />

there<strong>for</strong>e in<strong>for</strong>m a detailed design utilising current and location specific geotechnical data.<br />

Peat Stability Risk<br />

13.6.25 The Peat Stability Risk Assessment report included in Appendix 13.2 has identified a low to<br />

medium baseline qualitative risk of peat stability <strong>for</strong> the site. The semi-quantitative<br />

assessment has identified that under the loaded scenario, the Factor of Safety (FOS) would<br />

be


Carron Valley Wind Farm<br />

13.6.31 Treated water can also be discharged onto vegetated surfaces and directed away from<br />

watercourses and drainage ditches to avoid direct entry into watercourses. For discharge<br />

onto rough grasslands to be effective the discharge must be spread efficiently.<br />

Turbine Hardstandings<br />

13.6.32 Turbine hardstandings will be designed in such a way that surface water will infiltrate through<br />

the relatively permeable surface or will discharge into the associated road drainage .This<br />

means that overall runoff rates remain close to greenfield conditions.<br />

Site Tracks<br />

13.6.33 The construction depths of new tracks will vary depending on the ground conditions<br />

encountered. A cut track construction method will be used on firm granular <strong>for</strong>mation surface<br />

and existing tracks will be used and upgraded between the site entrance and construction<br />

compound.<br />

13.6.34 The tracks will be constructed with sufficient camber or crossfall to minimise ponding of<br />

surface water on the track surface. Any surface water not infiltrating through the access track<br />

base will be directed into infiltration trenches and/or drainage ditches prior to being<br />

discharged into settlement ponds. These SuDS measures will treat and attenuate the runoff<br />

be<strong>for</strong>e discharging back into the natural drainage network. Infiltration trenches and drainage<br />

ditches will be constructed with outlets at frequent intervals to limit the volume of water<br />

collected in a single channel, thus reducing the erosive potential and allowing runoff from<br />

upslope of a track to pass underneath the access track. These measures will minimise the<br />

risk of erosion of the track surface and the subsequent risk of sedimentation.<br />

13.6.35 Where the access tracks are constructed across natural areas of drainage such as flushes<br />

and springs, drainage measures in the <strong>for</strong>m of drainage pipes will be installed under the<br />

access track to allow the run-off to continue to follow its natural course. Where required<br />

existing field drains will be reconfigured to ensure an effective drainage of the area and to<br />

prevent surface water ponding behind tracks.<br />

13.6.36 In general, the SuDS proposed as part of the access tracks and other infrastructure are<br />

predicted to reduce any potential effect on runoff characteristics to baseline conditions. This<br />

is due to:<br />

• The sparse distribution of the proposed infrastructure, without large continuous<br />

impermeable areas. The total surface area of proposed infrastructure does not exceed<br />

1.3% in any sub-catchment.<br />

• Access tracks and hard standing areas will be constructed using graded bedrock<br />

allowing some surface water infiltration and drainage through adjacent soils.<br />

• Where drainage ditches are required, outfalls will be distributed along the ditches to<br />

minimise runoff rates and to allow infiltrate into adjacent soils.<br />

13.6.37 Where tracks are situated near deep peat, drainage systems will be adapted to ensure that<br />

the water table in the adjacent peat is not affected or only affected over a short distance. For<br />

example, drainage ditches along the track will be as shallow as possible sufficient to drain<br />

rainfall from the track surface and to prevent runoff flooding the track. The track surface will<br />

be near the adjacent peat surface and cross-drains will be installed at or just below the track<br />

surface. These measures will ensure that runoff within the upper peat layer (acrotelm) is not<br />

blocked by the track. The track base will be constructed using suitably permeable graded<br />

material such that the slow movement of water in the deeper peat layers is not significantly<br />

affected by the track.<br />

Watercourse Crossings<br />

13.6.38 The location of the existing watercourse crossings on site are shown in Figure 13.2. The<br />

proposed wind farm access tracks require upgrading, which will require all but one of the<br />

existing water crossings to be upgraded.<br />

13.6.39 Upgrading of the existing water crossings is considered to be the best environmental option,<br />

in comparison with replacing the existing crossings completely. Removing the crossings<br />

would require significantly more excavation works, would effect a greater length of the burn<br />

bed and banks, and would potentially pose a greater pollution risk due to the release of<br />

sediments during construction.<br />

13.6.40 Location of the new site access tracks required <strong>for</strong> the development has been minimised to<br />

avoid the need <strong>for</strong> water crossings where possible. As such, no additional water crossing will<br />

be required. Details of the existing structures are provided in Appendix 13.3.<br />

13.6.41 Confirmation of the type of any CAR authorisations required <strong>for</strong> upgrading the existing water<br />

crossings will be confirmed with SEPA in advance.<br />

13.6.42 Extended crossing structures will not <strong>for</strong>m a barrier to aquatic fauna, and will be designed<br />

and constructed with respect to relevant guidance and best practice. An assessment of the<br />

potential effects from extension of existing structures on aquatic fauna is presented in<br />

Chapter 11: Terrestrial Ecology.<br />

13.6.43 Where access tracks cross artificial drainage ditches, simple pipe structures will be installed.<br />

The pipe invert levels will be installed slightly below upstream and downstream bed levels to<br />

ensure that barriers <strong>for</strong> fish passage and sediment transport are minimised. Any potential<br />

effects arising from the artificial drainage is presented in Chapter 11: Terrestrial Ecology.<br />

13.6.44 Watercourses, crossings and drainage ditches will be inspected and cleared regularly to<br />

prevent blockages and remove the risk of flooding throughout the construction and<br />

operational life of the wind farm.<br />

On-Site Buildings<br />

13.6.45 On-site welfare facilities will be adequately designed and maintained to ensure all wastewater<br />

and sewage is disposed of appropriately. This disposal is likely to take the <strong>for</strong>m of either a<br />

closed on-site septic tank with tankering offsite <strong>for</strong> disposal or a suitable on-site treatment<br />

system with discharge to soakaway. Design of the final system will require further<br />

consultation with and authorisation from SEPA.<br />

13.6.46 Rainfall on roofs will be collected in a rainwater tank <strong>for</strong> re-use within the building. Any<br />

excess rainwater will be discharged to groundwater or surface water.<br />

13.6.47 The sizing and location of the various elements of the drainage system will be influenced by<br />

the topography, gradient and catchment runoff characteristics and the volumes of runoff<br />

intercepted by each drain. These factors will be determined at the detailed design stage.<br />

Cables<br />

13.6.48 Where cables are required to be buried, the following mitigation shall be put in place:<br />

• Excavations <strong>for</strong> trenches will be of minimal size necessary to undertake works;<br />

Carron Valley Wind Farm<br />

• Cable trenches will be dug, cables laid and filled in sections to minimise the areas of<br />

active excavation open at any one time; and<br />

• Bunds will be placed along the route of the buried cable route to prevent the creation of<br />

a preferential pathway <strong>for</strong> groundwater arising along the path of the cable.<br />

Concrete Batching and Pouring<br />

13.6.49 If concrete batching is to be undertaken on site, it should be undertaken only in a designated<br />

area, away from watercourses, private water supplies, wetland areas and in an impermeable<br />

area.<br />

13.6.50 Washout from concrete batching and drainage from the concrete batching area will be<br />

collected in a separate drainage system and treated be<strong>for</strong>e being discharged.<br />

13.6.51 When concrete is being poured shutters will be used and, if being poured into an excavation,<br />

only into an area free from standing water. Pumps should be used to keep excavations dry if<br />

required.<br />

13.6.52 Concrete batching and pouring will not be undertaken during adverse weather.<br />

Traffic<br />

13.6.53 Site traffic will be kept to clearly designated tracks, in line with a site-specific traffic<br />

management plan.<br />

13.6.54 Barriers and/or netting will be used to prevent vehicle movements in sensitive areas.<br />

13.6.55 Where vehicle movements are required to take place off-track, e.g. on soft ground during<br />

construction phase, these will be limited to the absolute minimum and where excessive offtrack<br />

vehicle movements are required, temporary tracks (e.g. geotextile overlain with<br />

aggregate) or peat-boards should be used to prevent damage to the soil and creation of<br />

sediment laden runoff.<br />

13.6.56 If there is a requirement to wash vehicles on-site or as they enter, or leave site, this activity<br />

should be undertaken in a designated area that bunded to prevent uncontrolled runoff or<br />

release of water from the washing process. All water and runoff arising from vehicle washing<br />

will be controlled and treated prior to discharge back into any watercourse.<br />

13.7 Assessment of Residual Effects<br />

13.7.1 Table 13.16 presents a summary of the predicted effects identified in this chapter and an<br />

assessment of the residual significance of effects following the implementation of mitigation<br />

measures identified in the previous section. The tables are followed by a discussion of the<br />

overall significance of effects by way of summary.<br />

Hydrology, Hydrogeology and Ground Conditions


Carron Valley Wind Farm<br />

Summary of Residual Effects<br />

13.7.2 In this chapter the potential effects of the construction, operation and decommissioning of the<br />

proposed Carron Valley Wind Farm on the hydrology, hydrogeology and geology have been<br />

assessed. The assessment demonstrates that the most significant effects have the potential<br />

to occur during the construction phase. The potential effects during the operation and the<br />

decommissioning phase are limited.<br />

13.7.3 The chapter has identified a number of mitigation measures that will be implemented to<br />

reduce the magnitude and there<strong>for</strong>e significance of potential effects. Following mitigation, all<br />

potential effects are reduced to negligible or minor.<br />

13.7.4 Overall, the effects of the proposed wind farm development on the site’s hydrological,<br />

hydrogeological and geological regime are considered to be of negligible to minor<br />

significance with mitigation.<br />

Fluvial System<br />

13.7.5 The impact assessment has taken into account the site’s hydrological regime including the<br />

natural runoff patterns and the location of all watercourses. Runoff rates and drainage<br />

patterns could be affected during the construction of the proposed wind farm due to<br />

excavation works and the construction of tracks and hard standing areas. However, this will<br />

be effectively mitigated by providing an adequately designed drainage system.<br />

13.7.6 The hydrological effect on the peat has been minimised by the design of the development<br />

layout which avoids areas of deep peat. Where tracks are near deep peat, drainage systems<br />

will be adapted to minimise lowering of the water table and to prevent draining of the peat or<br />

barriers to natural flow paths in the upper and lower peat layers.<br />

13.7.7 Effects on river flows and flooding are predicted to be very limited.<br />

Surface Waters<br />

13.7.8 Water quality within nearby waterbodies is classified as “poor” (River Carron, Carron Valley<br />

Reservoir, classed as a Heavily Modified Water Body) and “moderate” (Endrick Water).<br />

13.7.9 Pollution of surface water could potentially occur during the construction activities. A range of<br />

mitigation measures have been presented in this chapter to prevent pollution and these<br />

measures will be detailed in the HSEMS.<br />

Soils<br />

13.7.10 The impact assessment has identified that the main effects on soils are changes to drainage<br />

patterns as a result of compaction and construction of foundations/infrastructure. These<br />

effects are of limited extent focussed on the proposed access tracks and turbine locations<br />

and as such are considered to be of moderate significance, which would be mitigated to slight<br />

through the implementation of the drainage mitigation measures detailed in this chapter.<br />

Superficial Deposits & Geology<br />

13.7.11 The impact assessment has identified that the main effects on superficial deposits and<br />

geology are disturbance as a result of foundation excavations. With mitigation in place the<br />

effect is considered to be small and the residual effects are considered to be negligible.<br />

Carron Valley Wind Farm<br />

Hydrogeology<br />

13.7.12 Pollution of groundwater could potentially occur during the construction and operational<br />

activities. A range of mitigation measures have been presented in this chapter to prevent<br />

pollution and these measures will be identified in the HSEMS. The residual risk of chemical<br />

pollution of groundwater is not considered significant.<br />

13.7.13 The impact assessment has identified that the main effects on hydrogeology are likely to be<br />

changes to groundwater flow patterns in the area of proposed excavations. The shallow<br />

groundwater is however of low resource potential and any residual effects are likely to be of<br />

limited extent focussed on the proposed turbine locations and as such are considered to be<br />

of slight significance.<br />

Water Resources<br />

13.7.14 In<strong>for</strong>mation on the location of both private and public water supply systems has been<br />

collected to assess whether these could be affected by Carron Valley Wind Farm. No private<br />

water supplies are considered to be affected by the proposals, however there is a risk of<br />

effecting the water quality of public water supply sourced from the Carron Valley Reservoir<br />

and the Endrick Water. The residual effect is considered to be slight to negligible following<br />

implementation of the mitigation measures identified in this chapter.<br />

13.7.15 The assessment also concludes that flow rates within the watercourses are not significantly<br />

affected and that downstream abstractions are there<strong>for</strong>e not impacted by the development.<br />

13.8 Cumulative Effects<br />

13.8.1 RPS has identified 37 existing or proposed wind farm developments within 35 km of the<br />

proposed site with which there is the potential <strong>for</strong> cumulative effects to arise, as referred to in<br />

Chapter 9: Landscape and Visual Assessment , Figure 9.15).<br />

13.8.2 The closest wind farm to the proposed site is the Craigengelt Hill Wind Farm, approximately<br />

1 km north-east of the site, located within the Earls Burn and Easter Buckie Burn catchments,<br />

both of which are tributaries of the River Carron downstream of the Carron Valley Reservoir.<br />

Craigengelt Hill is currently operational.<br />

13.8.3 Earlsburn Wind Farm is an operational wind farm located approximately 1 km to the north,<br />

with an approved extension to the wind farm (known as Earlsburn North) 3 km to the north of<br />

the proposed Carron Valley Reservoir. This wind farm, including the extension, drains into<br />

the Earls Burn and Burnfoot and Backside Burns, which are tributaries of the Endrick Water.<br />

13.8.4 Craigannet Wind Farm is currently at application stage. If this wind farm proceeds it would<br />

be located less than 1 km to the east of the proposed site, within the Carron Valley Reservoir,<br />

River Carron and Earls Burn catchments.<br />

13.8.5 Kingsburn Wind Farm is currently at scoping stage. The proposed wind farm is located<br />

approximately 2 km to the west of the Carron Valley site. If this development proceeds, the<br />

site would be drained by several tributaries of the Backside Burn and the Belmenoch Burn,<br />

which are tributaries of the Endrick Water. It may also lay within the Loch Walton catchment.<br />

13.8.6 As the proposed site of the Carron Valley Wind Farm drains into the Carron Valley Reservoir<br />

and Endrick Water, there is the potential <strong>for</strong> cumulative effects to arise from pollution of<br />

watercourses (suspended solids or oils, <strong>for</strong> example). However, the existing Earls Burn Wind<br />

there<strong>for</strong>e it is considered that cumulative effects will be negligible.<br />

13.8.7 However, should one of these proposed wind farms be constructed at the same time as<br />

Carron Valley, then there may be an increased cumulative risk from sedimentation in<br />

catchments where more than one wind farm is being constructed at the same time, and<br />

increased monitoring in construction areas draining into that catchment will be required.<br />

13.8.8 All other developments in Figure 9.15 are either outwith the same catchments and/or at such<br />

a distance that any cumulative hydrological, hydrogeological or geological effect is not<br />

considered likely to result.<br />

14 Shadow Flicker<br />

14.1 Introduction and Overview<br />

14.1.1 Shadow flicker is the effect caused when rotating blades of a wind turbine cause a shadow to<br />

be cast on neighbouring properties and receptors. As the blades rotate, shadows on the<br />

ground or nearby properties move, resulting in a flicker effect. The effect occurs under<br />

certain combinations of factors including geographical position and time of day and can occur<br />

inside buildings, where the flicker appears through a window opening.<br />

14.1.2 The likelihood and duration of effects depends on:<br />

• The position of the observer in relation to the turbine(s) – In the UK, only properties<br />

within 130 degrees either side of north, relative to the turbines, are likely to be affected<br />

as turbines do not cast long shadows on their southern side;<br />

• Distance from turbine(s) – The further the observer is from the turbine, the less<br />

pronounced the effect would be. Due to factors such as shadow duration and focus,<br />

shadow flicker effects have been proven to occur only at distances up to ten times the<br />

turbine rotor diameter;<br />

• Wind direction – The turbine will not always be directed towards the receptor i.e.<br />

‘square-on’ which is the worst case scenario, there<strong>for</strong>e the effect will be minimised;<br />

• Turbine height and rotor diameter – The turbine height and rotor diameter can effect<br />

the distances at which shadow flicker can occur;<br />

• Time of year and day – The intensity of the sunlight can be diminished depending on<br />

the time of year, <strong>for</strong> example the sun does not shine brightly enough at certain periods<br />

of the year (e.g. winter months) to create the necessary contrast; and<br />

• Weather conditions – Cloud cover diminishes the intensity of sunlight.<br />

14.1.3 An assessment has been carried out to identify whether shadow flicker is likely to occur at<br />

properties neighbouring the proposed wind farm, and if so, to predict times of day/year and<br />

duration of these potential effects.<br />

14.1.4 It should be noted that, due to the design of the proposed wind farm layout in relation to<br />

potentially sensitive receptors, there is not considered to be the potential <strong>for</strong> significant<br />

shadow flicker effects to arise. However, in recognition of the interest in this potential effect<br />

this chapter has been retained within the <strong>ES</strong> to provide in<strong>for</strong>mation on the way in which<br />

potential shadow flicker effects were assessed and addressed through the design evolution<br />

process (see Chapter 3: Design Evolution).<br />

14.2 Methodology<br />

14.2.1 A study area was initially defined based on a distance of ten times the maximum proposed<br />

turbine rotor diameter and mapped using Geographical In<strong>for</strong>mation Systems (GIS) software<br />

(based upon Scottish Government advice – see below). The study area is then further<br />

refined to only include areas within 130 degrees either side of north of each turbine location.<br />

This study area is referred to as the zone of potential shadow flicker.<br />

Carron Valley Wind Farm<br />

14.2.2 Where habitable properties lie within the refined study area the dates, times and durations of<br />

shadow flicker events are then predicted <strong>for</strong> each property within the zone of potential<br />

shadow flicker using ReSoft WindFarm software. This software creates a mathematical<br />

model of the proposed wind farm, the surrounding area and the location of properties.<br />

14.3 Baseline In<strong>for</strong>mation<br />

Sources of Data<br />

14.3.1 Data was obtained through site visits, stakeholder consultation and desk based review of OS<br />

base mapping.<br />

Planning Policy Review<br />

14.3.2 The following documents provide guidance on the environmental effects of wind turbines and<br />

have been referenced during this assessment:<br />

• Scottish Government On-line Renewable Advice – Onshore Wind Turbines (Scottish<br />

Government, 2011);<br />

• Planning <strong>for</strong> Renewable Energy – A Companion Guide to PPS 22 (Office of the Deputy<br />

Prime Minister, 2004);<br />

• The Stirling Council Local Plan (adopted December 1999); and<br />

• Stirling Council Supplementary Planning Guidance – Wind Turbines (March 2011).<br />

Scottish Government On-line Renewable Advice<br />

14.3.3 Scottish Government in<strong>for</strong>mation and planning advice on the technologies <strong>for</strong> renewable<br />

energy is available in the <strong>for</strong>m of a series of web-based advice documents. The document<br />

“Onshore Wind Turbines” is applicable to the proposed wind farm.<br />

14.3.4 In respect of shadow flicker, the document states: “Under certain combinations of<br />

geographical position, time of day and time of year, the sun may pass behind the rotor and<br />

cast a shadow over neighbouring properties. When the blades rotate, the shadow flicks on<br />

and off; the effect is known as “shadow flicker”. It occurs only within buildings where the<br />

flicker appears through a narrow window opening. The seasonal duration of this effect can<br />

be calculated from the geometry of the machine and the latitude of the potential site. Where<br />

this could be a problem, developers should provide calculations to quantify the effect. In<br />

most cases however, where separation is provided between wind turbines and nearby<br />

dwellings (as a general rule 10 rotor diameters), “shadow flicker” should not be a problem.<br />

However, there is scope to vary/reduce the height of the turbines in extreme cases.”<br />

Planning <strong>for</strong> Renewable Energy – A Companion Guide to PPS 22<br />

14.3.5 In 2004, the Office of the Deputy Prime Minister published Planning <strong>for</strong> Renewable Energy, A<br />

Companion Guide to PPS 22. This document was prepared to provide additional in<strong>for</strong>mation<br />

in relation to Planning Policy <strong>Statement</strong> 22: Renewable Energy (PPS22). Although PPS22 is<br />

only applicable in England and Wales, the companion guide provides, in its Technical Annex,<br />

technical in<strong>for</strong>mation on a range of renewable energy technologies, including wind power,<br />

much of which is universally applicable. It expands on the in<strong>for</strong>mation presented in Scottish<br />

Government Planning Advice - Onshore Wind Turbines with regard to shadow flicker within<br />

Technical Annex 8, paragraph 73 – 77 of the Companion Guide.<br />

Stirling Council Local Plan<br />

14.3.6 Policy E10 of the SCLP rein<strong>for</strong>ces support <strong>for</strong> developments if they accord with other policies<br />

in the Plan and they avoid significant adverse impacts.<br />

14.3.7 For larger scale wind farms, like Carron Valley, there will be a presumption in favour of<br />

development within areas of defined countryside provided the following criteria are met<br />

including that the development will not affect the amenities of neighbouring occupiers<br />

unacceptably by reason of noise, visual dominance, shadow flicker, reflected light or other<br />

emissions.<br />

Stirling Council Supplementary Planning Guidance – Wind Turbines (March 2011)<br />

14.3.8 The Supplementary Planning Guidance sets out local guidance and criteria advising that<br />

proposals within or outwith identified areas will be assessed on their merits. Criteria which<br />

proposals will be assessed against includes avoidance of significant detrimental effects upon<br />

nearby residential amenity, including shadow flicker.<br />

Baseline Conditions<br />

14.3.9 A study area of ten times the maximum proposed turbine rotor diameter of 90 m, totalling<br />

900 m, was applied to each turbine location and mapped using GIS software. The study area<br />

was then further refined to only include areas within 130 degrees either side of north of each<br />

turbine location to obtain the zone of potential shadow flicker as presented on Figure 14.1.<br />

14.3.10 Only one property ‘Craigannet’ was identified within the zone of potential shadow flicker (see<br />

Figure 14.1). From analysis of Ordnance Survey (OS) mapping, site visits and discussions<br />

with stakeholders ‘Craigannet’ was identified as derelict and uninhabited and was there<strong>for</strong>e<br />

not considered further within this assessment. In addition, a search of the Stirling Council<br />

Online Planning System did not identify any valid planning applications <strong>for</strong> the property.<br />

14.3.11 No further properties were identified within the zone of potential shadow flicker as shown on<br />

Figure 14.1.<br />

14.4 Design Evolution<br />

14.4.1 The location of residential properties was identified early in the design process in order to<br />

locate turbines in such a way that no potentially sensitive receptors fell within the zone of<br />

potential shadow flicker <strong>for</strong> any individual turbine location.<br />

14.4.2 The shadow flicker model was re-run throughout the design iteration process to ensure that<br />

this remained the case, and the final 15 turbine wind farm layout as proposed does not result<br />

in any potentially sensitive receptors located within the zone of potential shadow flicker.<br />

14.5 Potential Significant Effects of the Scheme Prior to Mitigation<br />

14.5.1 As no inhabited properties were identified within the zone of potential shadow flicker, no<br />

significant effects have been identified.<br />

14.6 Mitigation and Enhancement Measures<br />

14.6.1 No mitigation measures are required.<br />

15 Socio-Economics, Tourism, Land Use and Recreation<br />

15.1 Introduction<br />

15.1.1 This chapter provides an assessment of the potential socio-economic, tourism, land use and<br />

recreation effects of the construction, operation and decommissioning phases of the<br />

proposed wind farm.<br />

15.1.2 In particular, this chapter examines:<br />

• Effects on employment and the economy;<br />

• Effects on land use and the economy;<br />

• Effects on tourism and perceptions of visitors; and<br />

• Effects on recreation and outdoor access.<br />

15.1.3 It is noted that the effects upon land use, tourism, recreation and outdoor access may have<br />

wider effects on the economy and employment and this is taken into account within the<br />

assessment.<br />

15.2 Methodology<br />

Assessment Methodology<br />

15.2.1 There is no prescribed methodology or standard guidance <strong>for</strong> assessing socioeconomic and<br />

related effects in EIA. The method adopted is there<strong>for</strong>e one of determining the existing<br />

circumstances (the baseline conditions) through desk based analysis. The potential effects<br />

of the proposed wind farm on this baseline are then identified and, where relevant, mitigation<br />

measures proposed, and then professional judgement is applied to determine the<br />

significance of any predicted residual effects.<br />

15.2.2 Determining the significance of predicted effects is a function of the magnitude of the<br />

predicted effect and the sensitivity of the receptor. Whether the predicted effect is considered<br />

to be positive or negative is also influential in determining the significance of effects.<br />

Effect Magnitude<br />

Response<br />

Access and Recreation<br />

The Carron Valley is an area important <strong>for</strong> recreation. SNH<br />

recommends that the <strong>ES</strong> overall should address the following<br />

matters in respect of recreation and access:<br />

• The effect on the enjoyment of any strategic access routes in the<br />

area.<br />

• The use of boundary features and essential access controls to<br />

ensure that these are not a barrier to the general right of access.<br />

• Increased noise and other changes in experience of the area<br />

from its present character.<br />

The <strong>ES</strong> should deal with the temporary and permanent effects of the<br />

proposal on recreation and access. SNH would expect that an<br />

assessment will be made of how current and future recreatiional use<br />

is likely to be affected during construction and subsequent operation<br />

of the wind farm.<br />

Impact on Gateway and Journeys through the National Park<br />

The ZVI <strong>for</strong> 126m high turbines suggests that potentially 4-16<br />

turbines tips will be visible from some of the key ‘gateway routes’ to<br />

the south and east of the Park. For example the A811 from Balloch,<br />

the A81 from Aberfoyle and from the A82 Alexandria to Luss. It is<br />

also visible from the minor roads entering the Park from across the<br />

Campsies (B822) and from Fintry (B818).<br />

Impact on Key Recreational Routes<br />

The ZVI <strong>for</strong> 126m high turbines suggests that they will be visible from<br />

a number of key summit routes including Ben Lomond (35km), Ben<br />

Ledi (25km) and the Mentieth Hills (20km) and Luss Hills (35km). It<br />

will also be visible from a number of core paths and smaller hills<br />

within the National Park such as Conic Hill as well as the West<br />

Highland Way, NCR7, some areas of Loch Lomond itself and key<br />

visitor destinations within the Park such as David Marshall Lodge.<br />

consider in order to minimise adverse local effects that could impact on tourism and<br />

recreation. These include:<br />

Carron Valley Wind Farm<br />

• The location of the proposed development in relation to tourist routes, including<br />

designated walking and cycling routes.<br />

• The relative scale of recreation and tourism in the area (i.e. local and national).<br />

• Views from accommodation in the area.<br />

• The potential positive tourism issues associated with the development.<br />

• The views of tourist organisations.<br />

• The visitor population whose recreational interests may be affected.<br />

Baseline Conditions<br />

Population<br />

15.3.4 The site of the proposed wind farm falls within the Census Area Statistic (CAS) wards of<br />

Bannockburn West and Campsies (see Figure 15.1) which lie within Stirling local authority.<br />

15.3.5 Mid-year population estimates <strong>for</strong> local authority areas in Scotland are produced each year<br />

by the National Records of Scotland. In 2010, the total population of Stirling was estimated to<br />

be 89,850, approximately 1.7 % of the Scottish population. This represents an increase of<br />

1.3 % since the 2009 mid year population estimate of 88,740 and is significantly higher than<br />

the Scottish average of 0.5 %. Most of this population growth within Stirling has been as a<br />

result of an estimated net in-migration of 1,039 people. However, there has also been a<br />

“natural” increase in population with births outnumbering deaths by 60 over the year. 1<br />

15.3.6 According to the 2001 census, Bannockburn West has a total population of 4,346 and<br />

Campsies a total population of 3,850. This represents 5.0 % and 4.5 % of the total<br />

population of Stirling respectively. This consisted of 3,943 males and 2,295 females in<br />

Bannockburn West and 1,892 males and 1,958 females in Campsies. There are no reliable<br />

estimates <strong>for</strong> these ward areas since the 2001 census figures. However, based upon small<br />

area population estimates at datazone level from Scottish Neighbourhood Statistics, it is<br />

estimated that the current population levels will have increased within these wards at a<br />

similar rate to those within Stirling.<br />

15.3.7 According to the 2001 census, Bannockburn West had a population density of 0.59 persons<br />

per hectare and Campsies had a population density of 0.18 persons per hectare. The figure<br />

<strong>for</strong> Stirling is 0.39 persons per hectare and <strong>for</strong> Scotland is 0.65 persons per hectare.<br />

15.3.8 Table 15.5 highlights the age structure of Bannockburn West and Campsies and places them<br />

in the context of Stirling and Scotland. The age structure of Bannockburn West and<br />

Campsies are similar to the Scottish population as a whole. In Bannockburn West, persons<br />

aged 15 and under in the 2001 Census made up 23 % of the total population. This is larger<br />

than both Stirling and Scotland where 19 % are aged under 15 or under. In Campsies 26 %<br />

of the population are aged 35 to 49. This is larger than both Stirling and Scotland where<br />

22 % are aged 35 to 49 years. This reflects the fact that many middle-aged people from<br />

outwith the local area have moved in.<br />

15.3.10 The economic activity of all persons aged 16 to 74 years in Bannockburn West in the 2001<br />

Census was 64 %, which is slightly below the average <strong>for</strong> both Stirling and Scotland of 65 %.<br />

The percentage of Bannockburn West’s population in employment (employee or self<br />

employed) was 59 %, slightly above Stirling and Scotland’s rate of 58 %. The number of<br />

permanently sick / disabled people in Bannockburn West was 9 %, compared to 6 % <strong>for</strong><br />

Stirling and 7 % nationally.<br />

15.3.11 The economic activity of all persons aged 16-74 years in Campsies in the 2001 Census was<br />

70 %, significantly above the average <strong>for</strong> both Stirling and Scotland of 65 %. The percentage<br />

of Campsies population in employment (employee or self employed) was 66 %, significantly<br />

above Stirling and Scotland’s rate of 58 %. Self employment is more important in Campsies<br />

that nationally, with 16 % of people in Campsies being self employed compared to only 7 %<br />

nationally.<br />

15.3.12 The most recent unemployment statistics show that in January 2012 there were 2,052<br />

unemployed residents within the Stirling Council area, 4.7 % of all residents, lower than the<br />

Scottish average of 5.2 %. However, the number of employed residents in Stirling increased<br />

by 93 % between June 2006 and June 2011 (Nomis, 2012). This rise is directly attributed to<br />

the global recession.<br />

15.3.14 The above table demonstrates the significant importance of agriculture and <strong>for</strong>estry to<br />

Campsies with 8 % of all employed persons aged 16 to 74 employed in these sectors<br />

compared to 3 % <strong>for</strong> Stirling and only 2 % nationally. There is also a significantly high<br />

proportion of people in Campsies employed in education (11 %), reflecting the role of Stirling<br />

University. Within Bannockburn West there is a significantly high proportion of people<br />

employed in construction, with 11 % of all employed persons aged 16 to 74 employed in this<br />

sector compared to 8 % <strong>for</strong> Stirling and 7 % nationally.<br />

15.3.15 In terms of supply of skills, the travel to work origins of individuals working in Stirling Council<br />

Area shows that the labour market is quite contained. According to the 2001 Census data,<br />

almost two thirds of those working within the Stirling Council area live locally.<br />

15.3.16 According to the 2010 Annual Survey of Hours and Earnings (NOMIS, 2010), the median<br />

gross weekly earnings <strong>for</strong> full time employees in Stirling in 2010 was £529.10 per week,<br />

higher than the Scottish average of £486.90. This reflects the fact that the working age<br />

population within the Stirling Council area is generally highly qualified. According to the<br />

Annual Population Survey 2010 (Office <strong>for</strong> National Statistics, 2010) 40 % of the working age<br />

population have a VQ4 or above level qualification (degree level or above), compared with<br />

the 34 % average of Scotland’s working age population.<br />

15.3.17 In 2009, Stirling residents had higher levels of disposable income than the national average.<br />

Annual disposable income per head in Stirling, Perth & Kinross was £16,376 per head, higher<br />

than the Scottish average of £14,908 (Office <strong>for</strong> National Statistics, 2009).<br />

Socio-Economic Indicators<br />

15.3.18 The Scottish Index of Multiple Deprivation (SIMD) is a composite measure of deprivation<br />

based on a range of indicators including employment, income, health and education. The<br />

local area geography adopted by the Scottish Government <strong>for</strong> this measure is data zones.<br />

These zones are based on groups of census output areas and have populations of between<br />

500 and 1,000 household residents. There are 6,505 data zones in Scotland.<br />

15.3.19 The SIMD provides a relative ranking of 6,505 data zones across Scotland from the most<br />

deprived (ranked 1) to the least deprived (ranked 6,505). The site of the proposed wind farm<br />

falls wholly within data zone S01006078. In 2009, this data zone had an overall rank of 3,683<br />

of 6,505. This rank places data zone S01006078 in the 57 th percentile, well outwith the<br />

generally accepted range of “deprived” areas of the worst 20 %. However, closer<br />

examination of the individual domain rankings shows that the area is disadvantaged in terms<br />

of geographic access to services <strong>for</strong> which data zone S01006078 is ranked amongst the<br />

worst 8 % of data zones in Scotland.<br />

Land Use<br />

15.3.20 The proposed wind farm is located within the Carron Valley Forest, a commercial <strong>for</strong>estry<br />

plantation which is currently managed by Forestry Commission Scotland (FCS). The Carron<br />

Valley Forest lies within the Scottish Lowlands Forest District.<br />

15.3.21 Forestry and wood processing contributes some £650 million per year to the Scottish<br />

economy, and the wood chain sustains some 20,000 jobs (FCS, 2006, 2008a). Woodlands<br />

are also important <strong>for</strong> tourism. Overall, it is estimated that <strong>for</strong>est-related tourism contributes<br />

some £165 million to the economy (FCS, 2008b). However, woodlands can also provide a<br />

wide range of non-market benefits to society, <strong>for</strong> example opportunities <strong>for</strong> healthy exercise<br />

and habitats <strong>for</strong> plants and animals.<br />

15.3.22 The Scottish Forestry Strategy (SFS) (Scottish Executive, 2006) sets out the Scottish<br />

Government’s vision <strong>for</strong> Scottish woodlands 2 and identifies seven key themes that will help<br />

achieve the vision:<br />

• using <strong>for</strong>estry to mitigate the effects of climate change;<br />

2 ‘Woodland’ is defined by the FCS as all areas of land, larger than 0.25 hectares, where trees are growing. ‘Forestry’ is used by<br />

FCS to refer to the science, art and practice of managing woodland.<br />

• maximising the benefits of the timber resource;<br />

• supporting sustainable economic growth through the business development of the<br />

Scottish woodland sector;<br />

• supporting community development to improve quality of life and wellbeing;<br />

• improving access to woodlands, to help improve the health of Scotland;<br />

• protecting environmental and scenic quality;<br />

• helping to conserve and enhance Scotland’s biodiversity.<br />

15.3.23 The vision set out in the SFS includes the ambition to increase woodland cover to 25 % of<br />

land area by the second half of the century and emphasises the need to integrate woodland<br />

with other land uses. It identifies that expansion of well managed woodlands can help ensure<br />

that Scotland is:<br />

• Wealthier & Fairer – by, <strong>for</strong> example, underpinning a sustainable <strong>for</strong>est products<br />

industry, reducing the reliance of the UK on wood imports, and supporting the<br />

development of the rural economy.<br />

• Healthier – by providing a setting <strong>for</strong> in<strong>for</strong>mal recreation that encourages regular<br />

exercise and improves physical and mental wellbeing.<br />

• Smarter – by providing a focal point <strong>for</strong> outdoor education activity, an inspiring<br />

environment in which to learn <strong>for</strong> those who find <strong>for</strong>mal education difficult, and<br />

opportunities <strong>for</strong> people to volunteer, improve their skills and enhance their<br />

employability.<br />

• Safer & Stronger – by improving the quality of the environment in deprived and<br />

regeneration areas, contributing to the development of green networks and natural<br />

flood management, and by providing a focus <strong>for</strong> community involvement and<br />

community projects.<br />

• Greener – by conserving biodiversity, restoring lost habitats, helping species adapt to<br />

climate change, and mitigating the effect of climate change by acting as a carbon<br />

store, a source of carbon neutral building materials, and as a source of renewable heat<br />

and energy.<br />

15.3.24 A portfolio analysis of the National Forest Estate was conducted by FCS in 2006. The aim of<br />

the analysis was to assess the current condition of the estate to determine which <strong>for</strong>est<br />

blocks are best delivering economic and non-market public benefits. This analysis<br />

demonstrates that the Carron Valley Forest is delivering significant strong economic benefits<br />

from harvesting operations (greater than £5/tonne profit based on 2006 market conditions)<br />

and some non-market benefits from recreation (11,000 to 50,000 visitors per annum) (FCS,<br />

2009).<br />

15.3.25 The site of the proposed wind farm is situated within the Cairnoch main block of the Carron<br />

Valley Forest. The woodland structure of the Cairnoch main block is dominated by Sitka<br />

spruce with much smaller areas of other conifers and broadleaves. This is a legacy of the<br />

historic nature of planting in the area. Open space occupies a small percentage of the<br />

Cairnoch main block and comprises predominantly of the summit of Cairnoch Hill and an area<br />

around Sir John de Graham’s castle. The woodland was planted in the mid 20th century and<br />

a major programme of restructuring of this woodland is currently underway. Details of the<br />

proposed harvesting and restocking of this woodland can be found in the approved Forest<br />

Design Plan (FDP) <strong>for</strong> Cairnoch Hill (revised March 2012 following extensive wind blow) (see<br />

Appendix 4.1). It is proposed within the FDP that the Cairnoch main block will continue to be<br />

managed as commercial productive woodland, whilst also having regard to environmental,<br />

recreational, aesthetic and other objectives which, as outlined above, are as important to<br />

FCS as timber production.<br />

15.3.26 As well as commercial timber production, the Carron Valley Forest is used <strong>for</strong> a wide range of<br />

outdoor access and recreational uses. These are discussed later in this chapter.<br />

Tourism Attractions<br />

15.3.27 Tourism is vitally important to the Scottish economy. According to the VisitScotland around<br />

14.7 million tourists took overnight trips to Scotland in 2010, contributing over £4 billion to the<br />

Scottish economy. Tourism related employment in 2008 supported about 9 % of total<br />

employment in Scotland. The Scottish Government’s ambition is to grow tourism by 50 % by<br />

2015.<br />

15.3.28 The VisitScotland 2007 Visitor Experience Survey confirms the most important factor in<br />

determining the choice of Scotland as a holiday destination is its scenery, followed by the<br />

number of things to see and do and the nature and wildlife.<br />

15.3.29 Tourism in the Argyll, Loch Lomond, Stirling & Forth Valley Region is estimated by<br />

VisitScotland in 2010 to be worth £392 million to the economy (10 % of the total value of<br />

tourism in Scotland), derived from 1.79 million tourist trips (12 % of all trips) and 4.25 million<br />

overnight stays (6 % of all stays).<br />

15.3.30 The total revenue generated by tourism within the Stirling Council area in 2010 was<br />

estimated around £372.37 million, comprising £164.11 million with the City of Stirling and<br />

£208.26 million within rural Stirling. Visitors spent their money on a variety of things. In<br />

2010, £57.15 million was spent on food and drink, £56.59 million was spent on<br />

accommodation, £52.54 million on transport, £42.92 million on shopping and £19.23 million<br />

on recreation. This revenue accounted <strong>for</strong> 8,241 full time equivalent jobs in 2010 (STEAM<br />

Report, 2010).<br />

15.3.31 Tourists are drawn to the Stirling Council area <strong>for</strong> a variety of attractions. Stirling City Centre<br />

is the focus <strong>for</strong> the historical and tourist offering, whilst the highly accessible and expansive<br />

rural environment surrounding the city is also a major draw <strong>for</strong> tourists, offering a range of<br />

recreation opportunities as well as acting as a gateway to the Loch Lomond and the<br />

Trossachs National Park.<br />

15.3.32 The Stirling Council Visitor Survey (Lyn Jones 2010) is a comprehensive survey of visitors to<br />

the Stirling area. The survey identifies that:<br />

• Stirling Castle is the biggest draw <strong>for</strong> visitors to Stirling, with 80 % of visitors<br />

identifying it as a driver in the decision making process, up from 66 % in 2008/2009.<br />

The history of the city also plays an important role, with 54 % of visitors identifying it as<br />

a driver in their decision to visit the city.<br />

• The overwhelming majority of respondents stated they visited at least one tourism<br />

attraction during their visit, with Stirling Castle by far the most commonly visited<br />

attraction (88 % of those who visited at least one attraction). The Old Town Cemetery<br />

(18 %), Stirling Old Town Jail (14 %) and Church of the Holy Rude (13 %) were also<br />

visited by at least 10 % of visitors.<br />

• Shopping is an important activity <strong>for</strong> visitors to Stirling, and was the third most popular<br />

activity (40 %) after visiting attractions (80 %) and walking around (55 %).<br />

• 28 % of all visitors to Stirling (both day and overnight) visit the city on the way to or<br />

from the Loch Lomond and the Trossachs National Park.<br />

• Stirling Castle was identified by 54 % of respondents as the best or most enjoyable<br />

aspect of their stay. Specific aspects of the city such as its picturesque surroundings<br />

and views along with the history of Stirling were referenced by 35 % of respondents.<br />

Carron Valley Wind Farm<br />

• The majority of visitors are from Greater Glasgow, followed by those from Edinburgh,<br />

the local area (Denny, Kilsyth, Bonnybridge and Lennoxtown) and Stirling.<br />

• Just under half visit alone and almost a quarter are in small groups. Family groups<br />

account <strong>for</strong> less than 20 %.<br />

• Almost half of visitors visit frequently (more than once a month), but the number of first<br />

time visitors at over one in ten is still significant.<br />

15.3.34 As discussed later in this chapter, the majority of visitors to the Carron Valley Forest come <strong>for</strong><br />

mountain biking and outdoor access opportunities. In addition to vantage point locations,<br />

other popular destinations within the Carron Valley Forest include:<br />

• The main car park, located to the east of the Carron Valley Reservoir, which provides<br />

parking <strong>for</strong> approximately 40 cars, has accessible toilets picnic area and<br />

interpretation/orientation. The car park <strong>for</strong>ms the start point of the mountain biking<br />

tracks and loch shore trails discussed later in this chapter.<br />

• Sir John de Graham’s Castle, a scheduled ancient monument situated to the north<br />

west of Carron Valley Reservoir. The site is highlighted by FCS on its website, it is not<br />

currently signposted or promoted on the ground.<br />

• Duncarron, a proposed full-scale replica of a medieval <strong>for</strong>tified village currently being<br />

constructed by the Clanranald Trust located near the main car park (to the east of the<br />

reservoir below Cock Hill). It is the intention of the Clanranald Trust to develop the <strong>for</strong>t<br />

as a visitor attraction events space and education / training facility.<br />

15.3.35 The Carron Valley Forest also provides the venues <strong>for</strong> an in<strong>for</strong>mal events programme run by<br />

FCS that includes visits from a wide variety of users from pre-primary to elderly, and<br />

educational / ranger events largely led and promoted by other groups such as weekly Forest<br />

Kindergarten visits. Major events recently held on site include horse endurance, Rat Race<br />

endurance, rally driving and the Clanranald open day (FCS, 2012).<br />

15.3.36 Tourist attractions within 20 km of the proposed wind farm are shown on Figure 15.2 and<br />

include (but are not limited to):<br />

• Colzium House, Kilsyth – located approximately 6 km to the south of the proposed<br />

wind farm. Gifted to the community in 1937, it houses a local history museum and is<br />

surrounded by planned gardens with collections of conifers and shrubs.<br />

• Kilsyth Heritage, Kilsyth - located approximately 6.3 km to the south of the proposed<br />

wind farm. A museum dedicated to the heritage of the settlement of Kilsyth, it is<br />

located within the town’s library.<br />

• The Antonine Wall – a 60 km stone and turf Roman <strong>for</strong>tification stretching from<br />

Carriden on the Forth to Old Kilpatrick on the Clyde. In 2008 the Antonine Wall was<br />

inscribed as a UN<strong>ES</strong>CO World Heritage Site. The wall lies approximately 7.9 km from<br />

the proposed wind farm at its nearest point.<br />

• Bannockburn Heritage Centre, Stirling - located approximately 10.6 km to the north<br />

east of the proposed wind farm. This is the battlefield where in June 1314 King Robert<br />

the Bruce of Scotland defeated Edward II. A National Trust <strong>for</strong> Scotland site, there is a<br />

visitor centre and car park. The Heritage Centre attracted 50,751 visitors in 2009.<br />

15.3.41 Visitor accommodation supply within the Carron Valley area is more limited in supply and<br />

comprises:<br />

• Carronbridge - Carronbridge Hotel, a four room hotel to the east of the Carron Valley<br />

approximately 3.8 km from the proposed wind farm.<br />

• Fintry – The Culcreuch Castle Hotel (14 rooms), the Clachan Hotel (6 rooms), the<br />

Fintry Inn (2 self catering apartments), approximately 6.5 km from the proposed wind<br />

Access and Recreation<br />

15.3.42 The geographical make up of the Stirling Council area means that it is very attractive <strong>for</strong> a<br />

wide range of <strong>for</strong>mal and in<strong>for</strong>mal recreational and access activities. The Stirling Countryside<br />

Access and Recreation Strategy vision is “to improve access and recreation opportunities <strong>for</strong><br />

all to the countryside of Stirling district, whilst promoting responsible use, supporting rural<br />

economies and respecting current land management.”<br />

15.3.43 The West Highland Way is a long distance footpath which links Milngavie, just outside<br />

Glasgow to Fort William in the Highlands. It passes through parts of Stirlingshire near<br />

Killearn, approximately 15.8 km from the proposed wind farm at its nearest point.<br />

15.3.44 The Forth and Clyde Cycle Route is a long distance cycle route between Gourock and<br />

Edinburgh along the Union and Forth Canals and parts of the National Cycle Network. The<br />

route lies approximately 7.3 km to the south of the proposed wind farm at its nearest point.<br />

15.3.45 Almost three-quarters of Scottish adults visit woodland <strong>for</strong> recreation each year (FCS, 2007).<br />

A consultation draft of the Lowlands Forest District Community, Recreation and Tourism<br />

Strategy (FCS, 2011) was published in October 2011. The aim of the strategy is “to deliver<br />

meaningful benefits to the communities of Central Scotland.” The strategy aims to develop<br />

several key <strong>for</strong>ests with broader appeal as ‘Destination Sites’. Carron Valley is one of these<br />

proposed Destination Sites.<br />

15.3.46 As outlined above, The Carron Valley Forest Visitor Experience & Interpretation Plan (draft<br />

FCS, 2012) estimates that there are currently between 17,000 and 45,000 visits to Carron<br />

Valley Forest per year. Table 15.12 provides a breakdown of the key current user groups set<br />

15.3.47 The above table demonstrates the attractiveness of the Carron Valley as a local and regional<br />

resource <strong>for</strong> mountain biking.<br />

15.3.48 From the main car park, the Lochside Trail is a promoted 1.3 km family friendly waymarked<br />

trail <strong>for</strong> walkers to the south east of the Carron Valley Reservoir which runs along the shores<br />

of the reservoir, providing open views over the water and to the hills beyond. The Lochside<br />

Trail <strong>for</strong>ms part of a longer distance core path towards Meikle Bin as identified on the North<br />

Lanarkshire Core Path Plan.<br />

15.3.49 A second small in<strong>for</strong>mal car park <strong>for</strong> approximately six cars is located to the west of the<br />

Carron Valley Reservoir at Todholes. From the west car park there are no waymarked trails.<br />

However, access is promoted to Meikle Bin from the west car park. Meikle Bin, which lies to<br />

the south west of the Carron Valley Reservoir, is the highest peak in the Campsie Hills, rising<br />

to a height of 570 m.<br />

15.3.50 The Carron Valley Forest also has a number of <strong>for</strong>ests roads and tracks freely accessible<br />

under the terms of the Scottish Outdoor Access code (SOAC). These include <strong>for</strong>est roads<br />

and tracks around Cairnoch Hill which link into wider paths into the Kilsyth Hills beyond e.g.<br />

Ling Hill, Cringate Law, Hart Hill and Earl’s Hill and Sir John de Graham’s Castle.<br />

15.3.51 From the B818 the access tracks <strong>for</strong> Earlsburn Wind Farm provide further opportunities <strong>for</strong><br />

walkers, cyclists and horseriders. There is also a Core Path (as shown on the Stirling<br />

Council Core Path Plan) which runs along the eastern bank of the Endrick Water to<br />

Ballochearn (to the south east of Kippen). The location of other Core Paths in the local area<br />

are shown on Figure 15.3.<br />

15.3.52 Within the wider study area, The Touch – Gargunnock – Fintry Hills-Carron Valley area has<br />

an established and growing importance <strong>for</strong> recreation. Hill walking, touring by car and<br />

mountain biking are all popular. In the past there have been proposals <strong>for</strong> the whole area to<br />

be designated a ‘regional’ park. In addition to those Core Paths identified on Figure 15.3, the<br />

most popular walking routes around the area include:<br />

• From Carron Bridge to Kilsyth on the Tak Ma Doon Road.<br />

• Routes along the south-side of Carron Valley Reservoir into the Kilsyth Hill range.<br />

• The minor road (which links Stirling to the B818 at the west end of the Carron Valley<br />

Reservoir) and provides routes to Earl’s Hill, Lewis Hill and Sauchie Craig.<br />

• Through the Clampsie Glen at Clachan of Campsie.<br />

• Milton of Campsie to Clachan of Campsie via Lennoxtown on the Strathkelvin Railway<br />

Path.<br />

15.3.53 The most popular cycling routes in the local area include:<br />

• The Crow Road / Tak Ma Doon Road “loop” on the B822 – B818 –A303. This is a<br />

popular cycle touring, as well as time trial and training run route <strong>for</strong> road cycling clubs.<br />

• The Balfron circular on the B818 – B822 Crow Road, and on to the A891, the A81 and<br />

the A875.<br />

• Kippen to Lennoxtown on the B822 via Fintry.<br />

• The Forth & Clyde towpath to the Tak Ma Doon Road via the B802 from Auchinstarry<br />

15.3.54 Horse riding facilities in the local area include:<br />

• Meadowside Farm Livery at Banton;<br />

• Woodend Equestrian Centre at Kilsyth; and<br />

• Campsie Glen Livery.<br />

15.3.55 In terms of other recreational activities, the River Forth adjacent to Stirling, the River Allan at<br />

Bridge of Allan, the River Carron by Denny and the River Devon in Clackmannanshire offer<br />

good opportunities to catch salmon, brown trout, sea trout and grilse. The Carron Valley<br />

Reservoir (managed by Scottish Water) offers boat and bank fly fishing <strong>for</strong> rainbow trout and<br />

wild and stocked trout. National and international fishing events on the Carron Valley<br />

Reservoir are run by Carron Valley Fishery. There is also fishing on Loch Coulter Reservoir,<br />

North Third Reservoir and at Swanswater Fishery.<br />

15.3.56 In 2004, the Scottish Executive (now Scottish Government) published a study on the<br />

‘Economic impact of game and coarse angling in Scotland’. This study found that anglers<br />

spend almost £21.5 million a year in Central Scotland (including Stirling). Of this, nearly £11<br />

million is spent on angling <strong>for</strong> rainbow trout, whilst brown trout fishing accounts <strong>for</strong> a revenue<br />

of £5.2 million and salmon and sea trout a revenue of £3.4 million. The survey concluded that<br />

473,233 angler days a year were spent fishing in Central Scotland. It also indicated the effect<br />

that a loss of angling would have on regional employment. If rainbow trout angling stopped<br />

entirely in Central Scotland, employment equal to 218 full time equivalent jobs would be lost.<br />

If brown trout angling stopped, employment equal to 43 full time equivalent jobs would be<br />

lost.<br />

15.3.57 Kilsyth Lennox Golf Club lies approximately 5.9 km to the south east of the proposed wind<br />

farm. The nearest golf course to the proposed wind farm within Stirling is Brucefield Family<br />

Golf Centre, a new 18 hole golf course to the southwest of Bannockburn. Stirling Golf<br />

Course, an 18 golf course which lies to the south west of the town, is approximately 11.3 km<br />

<strong>for</strong>m the proposed wind farm.<br />

15.4 Potential Significant Effects of the Scheme Prior to Mitigation<br />

Employment and the Economy<br />

15.4.1 The construction, operational and decommissioning phases of the proposed wind farm may<br />

have an effect on the following elements of the local and/or regional economies:<br />

• Expenditure – financial investment <strong>for</strong> a number of organisations who will be supplying<br />

services and goods <strong>for</strong> the construction and decommissioning of the proposed wind<br />

farm.<br />

• Employment – direct construction, operation and decommissioning employment, and<br />

indirect and induced employment further down the supply chain.<br />

15.4.2 Potential employment effects as a result of changing visitor numbers to tourism attractions,<br />

tourism accommodation providers and access and recreational facilities are considered later<br />

in this chapter.<br />

Expenditure<br />

15.4.3 The proposed wind farm is a large construction project with significant total capital costs<br />

(approximately £55 million). There may be opportunities <strong>for</strong> parts of the supply chain based in<br />

Scotland to capitalise upon this capital spend, albeit that it is recognised that the majority of<br />

the supply chain is primarily based in mainland Europe.<br />

15.4.4 The structure of the local economy is such that it is considered to have the capacity to benefit<br />

from expenditure associated with the proposed wind farm. The sensitivity of this receptor is<br />

there<strong>for</strong>e considered to be medium. During the construction phase, site preparation works<br />

would provide opportunities <strong>for</strong> materials and construction equipment to be sourced within the<br />

local area and Stirling. Although these would represent relatively small proportions of the<br />

total capital costs, this direct expenditure would be likely to recirculate and bring some<br />

benefits to the local economy. However, given there is no guarantee that materials and<br />

construction equipment would be sourced locally and given also that expenditure would only<br />

be <strong>for</strong> a short temporary period (approximately 20 months), the magnitude of this effect is<br />

considered to be small.<br />

15.4.5 The decommissioning phase would entail considerable expenditure at similar levels to that<br />

involved during the construction phase.<br />

15.4.6 Furthermore, whilst it is acknowledged not to be a material planning consideration, it should<br />

be noted that the proposed wind farm will also contribute to the local economy through<br />

provision of a community fund.<br />

15.4.7 A market-leading community benefit offering will be provided alongside any future<br />

development. This will consist of a Community Benefit Fund, which will receive an annual<br />

payment at the rate of £5,000 per installed megawatt. If fifteen 3 MW turbines are<br />

constructed, the fund would receive £225,000 on an annual basis (index linked) <strong>for</strong> the<br />

operational life of the project of between 20-25 years, amounting to over £5m in donations.<br />

Socio-Economics, Tourism, Land-Use and Recreation


Carron Valley Wind Farm<br />

The fund would be independently administered with decisions on funding allocations made by<br />

representatives of the local community.<br />

15.4.8 In the event that planning permission is granted <strong>for</strong> the site, a separate Community Benefit<br />

Fund consultation will take place in order to establish the community’s views on the best way<br />

to make use of this funding locally.<br />

15.4.9 In addition to the Community Benefit Fund, PfR has agreed with FCS that eligible community<br />

groups will be able to invest in the project, if they desire, up to a limit of 10 % at financial<br />

close. For eligibility criteria, community groups have been asked to refer to the National<br />

Forest Land Scheme guidance and register their interest with either PfR or FCS.<br />

15.4.10 Further discussion will take place with community groups throughout the planning period,<br />

during which more in<strong>for</strong>mation and guidance will be provided on the Forestry Commission<br />

Scotland website (http://www.<strong>for</strong>estry.gov.uk/communitiesandrenewables).<br />

15.4.11 Overall, a slight positive effect is anticipated to the local economy from project expenditure<br />

during the construction and decommissioning phases.<br />

Direct Employment<br />

15.4.12 In terms of employment, the construction of the proposed wind farm will directly support 40 to<br />

50 full time equivalent jobs <strong>for</strong> a period of approximately 20 months. It is estimated that the<br />

total value of the construction contracts would be in the order of £19 million.<br />

15.4.13 The structure of the local economy is such that it is considered to have the capacity to benefit<br />

from construction contracts associated with the proposed wind farm. Consequently the<br />

sensitivity of the receptor is considered to be medium. However due to the specialist nature<br />

of the turbine erection and installation work, there will be a greater competitive advantage <strong>for</strong><br />

experienced contractors who are likely to be located outwith the local area. This effect is<br />

there<strong>for</strong>e considered to be small in magnitude. Key opportunities <strong>for</strong> local firms and<br />

businesses during the construction work will be <strong>for</strong> site preparation and establishment,<br />

including access track and turbine hardstanding construction. Furthermore, construction of<br />

the proposed wind farm will also require a number of transportation services which may be<br />

provided by businesses in the local area. However, given that there is no guarantee that<br />

these services would be sourced locally the magnitude of this effect is considered to be<br />

small. Overall, a slight positive effect is anticipated to direct local employment during the<br />

construction phase.<br />

15.4.14 The operational phase of the proposed wind farm will directly support two to three operational<br />

manager jobs <strong>for</strong> the duration of the 25 year operational life of is the wind farm. Employees<br />

from the turbine manufacturer and/or contractors will also carry out maintenance and<br />

servicing at regular intervals, <strong>for</strong> which teams of between 5 and 8 staff will be required.<br />

There will be opportunities from suitably qualified locally based contractors to carry out this<br />

maintenance / servicing work. The structure of the local economy is such that it is considered<br />

to have the capacity to benefit from these operational employment opportunities.<br />

Consequently the sensitivity of the receptor can be assessed as medium. However, given the<br />

scale of employment opportunities associated with the operation of the proposed wind farm,<br />

this magnitude of this effect is considered to be small. Overall, a slight positive effect is<br />

anticipated to direct local employment during the operational phase.<br />

15.4.15 At the end of the proposed wind farm’s operational life, the decommissioning phase would<br />

necessitate employment at similar levels, and with comparable experience and expertise, to<br />

that involved in the construction phase. Overall, a slight positive effect is there<strong>for</strong>e anticipated<br />

to direct local employment during the decommissioning phase.<br />

Indirect and Induced Employment<br />

15.4.16 Indirectly, the proposed wind farm may also create further employment opportunities down<br />

the supply chain <strong>for</strong> those companies providing services to the contractors during the<br />

construction and decommissioning phases of the proposed development. .<br />

15.4.17 Whilst the level of employment created directly as a result of the proposed wind farm may be<br />

limited in terms of benefiting the local economy, there would be additional economic benefit<br />

relating to local businesses, in particular in providing accommodation <strong>for</strong> specialist<br />

construction workers. PfR estimates that the potential effect of the construction phase<br />

undertaken by contractors outwith the area that require accommodation, is between<br />

£230,400 and £550,000. This estimate is based on the following scenarios:<br />

• 80 weeks with 50 workers staying five nights per week at £55 per night <strong>for</strong> a twin room<br />

= £550,000; and<br />

• 64 weeks with 40 workers staying four nights per week at £45 per night <strong>for</strong> a twin room<br />

= £230,400.<br />

15.4.18 In addition, workers may select to stay in local accommodation and this would have a positive<br />

economic effect on other local services such as shops, pubs, cafes, takeaways etc.<br />

15.4.19 The structure of the local economy is such that it is considered to have the capacity to<br />

provide such services to contractors. Consequently the sensitivity of the receptor can be<br />

assessed as medium. However, given that there is no guarantee that contractors will make<br />

use of local businesses and given that the provision of such services would be <strong>for</strong> a short<br />

period of time, this magnitude of this effect is considered to be small.<br />

15.4.20 Overall, a slight positive effect in terms of indirect and induced local employment is<br />

anticipated.<br />

Land Use<br />

15.4.21 Construction and operation of the proposed wind farm will require the felling and permanent<br />

loss of 33.52 ha of commercial <strong>for</strong>estry land from within the Cairnoch block. The Forest<br />

Design Plan (FDP) directs all <strong>for</strong>estry operations, and is the subject of periodic review as the<br />

vagaries of weather, disease and markets can drive changes to the plan. In the case of<br />

Cairnoch Hill the storms of January 2012 resulted in such a review, and brought <strong>for</strong>ward the<br />

felling of compartments resulting in greater volumes of timber being harvested than would<br />

have been the case under the existing FDP. Given the extent of commercial <strong>for</strong>estry of<br />

similar age and structure locally, this receptor is considered to be generally tolerant to this<br />

loss and the sensitivity of this receptor is there<strong>for</strong>e considered to be low.<br />

15.4.22 The extension of the wind blow clearance to include the turbine infrastructure can be<br />

achieved by using the available work<strong>for</strong>ce, or transient <strong>for</strong>estry contractors that would<br />

normally resource such operations. In the short term, much of the crop generated from the<br />

construction of the wind farm will be sold and revenues generated. However, <strong>for</strong> the<br />

purposes of this assessment it has been assumed that, were the wind farm not to be built and<br />

operated, the extent of felling required <strong>for</strong> the purposes of the wind farm would eventually be<br />

felled under normal operations. Assuming the <strong>for</strong>estry operations continued over the lifetime<br />

of the wind farm it would not, there<strong>for</strong>e, be anticipated that there would be any significant net<br />

gain or loss with respect to timber sales resulting from the construction phase, and so the<br />

magnitude of effect is considered negligible. Sections of felled and replanted trees will<br />

continue to mature during the lifetime of the <strong>for</strong>est and the operations required to successfully<br />

establishing trees will be carried out without interruption. Following decommissioning of the<br />

wind farm, some of the area lost to the development footprint will be available to return to<br />

commercial <strong>for</strong>estry. The effect of the proposed development on commercial <strong>for</strong>estry is<br />

there<strong>for</strong>e considered to be negligible.<br />

Tourism and Recreation<br />

15.4.23 The actual effects of the operational phase of the proposed wind farm on tourist and<br />

recreational users is difficult to assess given that people’s perception of the landscape and<br />

visual effects of wind farms are entirely subjective. For example, even at locations where the<br />

proposed wind turbines may be a significant feature in the landscape, <strong>for</strong> some tourists or<br />

recreational users this may increase their enjoyment and their future propensity to revisit<br />

whilst <strong>for</strong> others the presence of turbines may decrease their enjoyment and propensity to<br />

revisit. Be<strong>for</strong>e assessing the effects and effects of the proposed wind on tourism and<br />

recreation, a literature review of surveys relating to the effects of wind farms on these matters<br />

is discussed below.<br />

Existing Tourism Evidence and Surveys<br />

15.4.24 A number of studies have been undertaken in order to determine the effect upon tourism and<br />

recreation interests of the presence of a wind farm in an area.<br />

15.4.25 The Scottish Government report ‘Economic Impacts of Wind Farms on Scottish Tourism’<br />

(2008) is considered to be the most comprehensive and robust study into the potential effects<br />

of wind farm developments on tourism. The study, which was based upon an extensive<br />

literature review and survey of 380 people, found that there is no evidence to suggest that<br />

wind farms have a serious negative economic effect on tourism. The key findings of the<br />

survey were that:<br />

• 75 % of people felt that wind farms have a positive or neutral impact on the landscape.<br />

• Those interviewed whose main activity was hiking or walking were more likely to feel<br />

that wind farms have a positive or neutral impact on the landscape (81 %).<br />

• 2 % of those interviewed who had seen a wind farm in the area (four respondents out<br />

of 191 who had seen a wind farm) said that it would affect their decision to visit the<br />

area again – two indicated that the likelihood would increase and two that the<br />

likelihood would decrease. The change impact was estimated at -0.08 %.<br />

those interviewed (11 out of 379 respondents) said that it would affect their decision to<br />

visit the area again. The change impact of this was estimated at -0.73 %.<br />

15.4.26 VisitScotland’s ‘Wind Farm Consumer Research’ (2012) provides the most up to date study<br />

into attitudes to wind farms and their effects on tourism. The study, which was based upon<br />

interviews with 1,000 people from within Scotland and 2,000 people from within the UK, found<br />

that <strong>for</strong> the majority of respondents (80 % of UK respondents and 83 % of Scottish<br />

respondents) that the presence of a wind farm would not affect their decision about where to<br />

stay when on holiday or on a short break. Other key findings of the study were that at<br />

present UK/Scotland consumers do not feel that that wind farms spoil the look of the<br />

countryside, with 81.4 % of UK respondents and 80.4 % of Scottish respondents claiming to<br />

disagree or neither agree or disagree with the statement that wind farms spoil the look of the<br />

countryside.<br />

15.4.27 VisitScotland’s report ‘Investigation into the Potential Impact of Wind Farms on Tourism in<br />

Scotland’ (2002) focused upon the perceived impact of wind farms as a comparative visual<br />

element in the countryside in ascertaining visitors’ views and the visual impact upon their<br />

visitor experience. The research demonstrates that, in general, respondents have a more<br />

positive than negative view towards the effects of wind farms on tourism. The majority of<br />

those surveyed had a neutral view. Positive views included that wind farms can be an<br />

attraction in themselves in the landscape if sensitively sited. They are perceived to have the<br />

potential to attract new markets and those visitors attracted by “environmentally friendly”<br />

energy and new technology. New wind farm developments were also identified as having the<br />

potential to provide greater access to remote areas and have a positive effect on the local<br />

economy. The main negative effect identified by respondents was the visual impact,<br />

particularly in rural, undeveloped areas, which was recognised to be intrusive and there<strong>for</strong>e<br />

detract from the visitor’s experience. Other negative effects included mental ‘barriers’ <strong>for</strong> the<br />

exploration of hills, effects on wildlife and effects on tourism businesses as a result of fewer<br />

visitors.<br />

15.4.28 Overall it is there<strong>for</strong>e concluded that there is there is no evidence that wind farms have a<br />

negative effect upon tourism or recreation interests and that <strong>for</strong> the vast majority of tourists,<br />

wind farms are not a major factor in their decision-making. Further, anecdotal evidence from<br />

other FCS wind farm sites that the improvements to path infrastructure and delivery of visitor<br />

experience enhancements can result in an increase in visitor numbers.<br />

Tourism Industry and Attractions<br />

15.4.29 There are relatively few tourist attractions within 20 km of the proposed wind farm which<br />

could have theoretical visibility. Beyond 20 km, it is considered that any effects upon tourist<br />

attractions would not be significant. It is notable that the most popular tourist attractions are<br />

located within Stirling where there would be no theoretical visibility of the proposed wind farm.<br />

In view of this it is considered that the proposed wind farm is unlikely to have a detectable<br />

effect upon the local and regional tourism industry. The sensitivity of this receptor is<br />

there<strong>for</strong>e considered to be small.<br />

15.4.30 Those tourist attractions within 20 km of the proposed wind farm that could have theoretical<br />

visibility include the National Wallace Monument, parts of the Antonine Wall, the Falkirk<br />

Wheel, Dunmore Pineapple, Menstrie Castle and Alloa Tower. Actual visibility from these<br />

attractions would be influenced by the localised effects of topography and vegetation as<br />

discussed below:<br />

• The National Wallace Monument: The landscape and visual impact assessment (<strong>ES</strong><br />

Chapter 9: Landscape and Visual Impact Assessment) establishes that there would be<br />

theoretical visibility of up to 2 turbine blade tips from the Wallace Monument. Site<br />

visits confirm that these two turbine tips would be barely perceptible and the character<br />

of the predominantly rural view would be maintained.<br />

• The Antonine Wall: The Zone of Theoretical Visibility (ZTV) predicts views of up to 11<br />

turbines along parts of the Antonine Wall between Falkirk and Bonnybridge. This<br />

includes Watling Lodge Fort and Tamfourhill Camp. However, local screening greatly<br />

affects the wider visibility of this section of the Wall. Within Falkirk, visibility from the<br />

wall is largely contained by built <strong>for</strong>m, whilst near the Falkirk Wheel the Wall is<br />

contained within woodland. Beyond the woodland near the Falkirk Wheel the ZTV<br />

establishes that there would be no visibility of the proposed wind farm.<br />

• The Falkirk Wheel: The ZTV predicts views of up to 3 turbines from the Falkirk.<br />

However, site visits confirm that the proposed wind farm would not be visible from this<br />

location.<br />

• Dunmore Pineapple: The ZTV predicts that up to 15 turbines would be visible from<br />

Dunmore Pineapple. However, site visits confirm that the walled garden and<br />

surrounding woodland would obscure views of the proposed wind farm.<br />

• Menstrie Castle: The ZTV predicts that up to 3 turbines may be visible from Menstrie<br />

Castle. However, site visits confirm that neighbouring housing would screen views of<br />

the proposed wind farm.<br />

• Alloa Tower: The landscape and visual impact assessment (<strong>ES</strong> Chapter 9: Landscape<br />

and Visual Impact Assessment) establishes that the blade tips of 8 turbines may be<br />

visible from Alloa Tower. Site visits confirm that views of these turbine blades,<br />

although perceptible, would be distant and would be seen as a slight intensification of<br />

existing developments in the view.<br />

15.4.31 On the basis of these findings it is considered that the proposed wind farm is unlikely to<br />

detract from visitor enjoyment and likely demand to visit any of these tourist attractions. The<br />

magnitude of this effect is there<strong>for</strong>e considered to be small. Overall, the proposed wind farm<br />

is there<strong>for</strong>e anticipated to have a slight negative effect on tourist attractions.<br />

15.4.32 With regard to the wider tourism industry and market, the majority of visitors are drawn to the<br />

City of Stirling and to Loch Lomond and the Trossachs National Park, both of which are<br />

considered to be of high sensitivity. As there would be no theoretical visibility of the proposed<br />

wind farm from Stirling city centre, there proposed wind farm would have no effect upon<br />

visitor numbers and the magnitude of effect is considered to be negligible, resulting in a<br />

negligible effect.<br />

15.4.33 With regards to gateways to the Loch Lomond and the Trossachs National Park, the A811<br />

from Stirling to Balloch, the A81 from Aberfoyle and the A82 from Glasgow to Luss are<br />

considered to be the main tourist gateways and are considered to be of medium sensitivity.<br />

Other minor roads which <strong>for</strong>m gateways to the Loch Lomond and the Trossachs National<br />

Park, including the B822 from the Campsies and the B8181 from the Carron Valley to Fintry,<br />

are considered to be of low sensitivity. For the purposes of this assessment, this level of<br />

sensitivity is based upon the conclusion that the primary purpose of travelling on these routes<br />

is to visit Loch Lomond and the Trossachs National Park itself.<br />

15.4.34 Visibility of the proposed wind farm on the main A road gateway routes to the Loch Lomond<br />

and the Trossachs National Park is discussed below:<br />

• A811 from Stirling to Balloch: The landscape and visual impact assessment (<strong>ES</strong><br />

Chapter 9: Landscape and Visual Impact Assessment) establishes that up to 4 km of<br />

the A811 to the south of Drymen may potentially experience views of the proposed<br />

wind farm. These views would be distant and would predominantly relate only to<br />

motorists travelling eastwards. Trees and woodland would intermittently obscure these<br />

distant views, and the proposed wind farm would <strong>for</strong>m only a minor, easily missed<br />

element in the view, visible <strong>for</strong> a few seconds on each occasion.<br />

Carron Valley Wind Farm<br />

• A81 from Aberfoyle: The landscape and visual impact assessment (<strong>ES</strong> Chapter 9:<br />

Landscape and Visual Impact Assessment) establishes that up to 1 km of the A81<br />

when travelling southbound at Aberfoyle may potentially experience distant oblique<br />

views of the proposed wind farm. The proposed wind farm would <strong>for</strong>m only a minor<br />

elements on the horizon of the Campsie Fells in the view.<br />

• A82 from Glasgow to Luss: The ZTV predicts that up to 6 km of the A82 to the south of<br />

Luss may experience views of the proposed wind farm. However, the landscape and<br />

visual impact assessment (<strong>ES</strong> Chapter 9: Landscape and Visual Impact Assessment)<br />

establishes that the dense tree cover along the shore of Loch Lomond immediately to<br />

the east of the A82 obscures all actual views towards the proposed wind farm.<br />

15.4.35 On the basis of these findings that the views of the proposed wind farm would only <strong>for</strong>m a<br />

small part of the total distance of the A811 and the A81 and, where experienced, the<br />

proposed wind farm would <strong>for</strong>m only a minor element of the view, it is considered unlikely that<br />

the proposed wind farm would deter visitors from using either of these main gateway routes.<br />

The evidence of the various surveys as identified above into the effect of wind farms on<br />

tourists supports this conclusion. The magnitude of this effect is there<strong>for</strong>e considered to be<br />

small, resulting in a slight negative effect. As there would be no views from the A82 from<br />

Glasgow to Luss, the magnitude of this effect is there<strong>for</strong>e considered to be negligible,<br />

resulting in a negligible effect.<br />

15.4.36 Visibility of the proposed wind farm on the other B road gateway routes to the Loch Lomond<br />

and the Trossachs National Park is discussed below:<br />

• B822 from the Campsies: The landscape and visual impact assessment (<strong>ES</strong> Chapter<br />

9: Landscape and Visual Impact Assessment) establishes that the proposed wind farm<br />

would be visible on the total 7 km distance from the top of the Campsies toward the<br />

B818. Although the proposed wind farm would <strong>for</strong>m a prominent new element in the<br />

view, this would be in the context of the existing Earlsburn Wind Farm which is of a<br />

similar scale. Views would predominantly relate only to motorists travelling northwards<br />

on this route.<br />

• B8181 from Fintry: The landscape and visual impact assessment (<strong>ES</strong> Chapter 9:<br />

Landscape and Visual Impact Assessment) establishes that there would be potential<br />

views of the proposed wind farm <strong>for</strong> up to 4 km of the B8181 to the west of Fintry.<br />

These views would be in addition to up to 13 km of potential views from along the<br />

B8181 from the Carron Bridge. However, actual views on the B8181 from Fintry would<br />

be intermittent and would be sometimes filtered by intervening vegetation. Where<br />

experienced, the turbines would be seen on the horizon as minor elements in the view,<br />

with the farmland, moorland and <strong>for</strong>estry remaining the dominant elements. Views<br />

would predominantly relate only to motorists travelling eastwards on this route.<br />

15.4.37 On the basis these finding on the B8181 from Fintry it is considered that the proposed wind<br />

farm is unlikely to detract from using this gateway route. The magnitude of this effect is<br />

there<strong>for</strong>e considered to be small, resulting in a slight negative effect.<br />

15.4.38 On the basis of these findings that there would be prominent views of the proposed wind farm<br />

on longer sections of the B822, this could result in some motorists not using this route as a<br />

gateway to the Loch Lomond and the Trossachs National Park. However, on the basis of the<br />

surveys identified above into the effect of wind farms on tourists, it is concluded that <strong>for</strong> the<br />

vast majority of motorist the presence of the wind farm on this route will not be a major factor<br />

in their decision to use this gateway route. The magnitude of this effect is there<strong>for</strong>e<br />

considered to be medium, resulting in a slight negative effect.<br />

15.4.39 Overall, the proposed wind farm is there<strong>for</strong>e anticipated to have a slight negative effect at<br />

worst on gateway routes to the Loch Lomond and the Trossachs National Park.<br />

Tourist Accommodation<br />

15.4.40 There is very limited accommodation supply within the immediate Carron Valley area <strong>for</strong> the<br />

proposal to result in a detectable change to visitor numbers and the economy of the area in<br />

general, with the majority of accommodation providers located around the periphery of the<br />

Campsies where there would be no theoretical visibility of the proposed wind farm. The<br />

sensitivity of this receptor is there<strong>for</strong>e considered to be low.<br />

15.4.41 Although it is possible that some potential visitors may be deterred from staying in tourist<br />

accommodation at Carronbridge and Fintry if there was a possibility that their view would be<br />

compromised, on the basis of the various surveys on the effects of wind farms on tourists<br />

identified above, it is considered that the number of such visitors would be small at worst. It<br />

is also expected that any losses incurred in this way would be compensated <strong>for</strong>, to some<br />

degree if not completely, by an increase in accommodation demand during the construction<br />

and decommissioning periods (as a result of contractors outwith the area that require<br />

accommodation) and from those visitors who are attracted to the Carron Valley by new<br />

access opportunities and facilities created as a result of the proposed wind farm. The<br />

magnitude of this effect is there<strong>for</strong>e considered to small at worst.<br />

15.4.42 Overall the proposed wind farm is there<strong>for</strong>e anticipated to have a slight negative effect at<br />

worst on tourist accommodation providers.<br />

Access and Recreation<br />

15.4.43 The majority of access and recreational activity in the Carron Valley Forest takes place to the<br />

south east of the Carron Valley Reservoir where the mountain biking, waymarked trail and<br />

car parking facilities are located. There is lower and less <strong>for</strong>mal visitor access to the site of<br />

the proposed wind farm.<br />

15.4.44 During the construction and decommissioning phases of the proposed wind farm it will be<br />

necessary to restrict access to the site <strong>for</strong> public safety reasons, including parts of the <strong>for</strong>est<br />

access tracks around Cairnoch Hill and the <strong>for</strong>est access track which connects to the core<br />

path towards Kippen. Given the currently low and in<strong>for</strong>mal use, the relatively short<br />

construction programme and the potential <strong>for</strong> diversions in some locations, the sensitivity of<br />

this receptor is considered to be low. As short closures <strong>for</strong> health and safety reasons already<br />

commonly occur during harvesting operations, the magnitude of this effect is considered to<br />

be small. Overall, the proposed wind farm is there<strong>for</strong>e anticipated to have a slight negative<br />

effect with regards to on-site public access during the construction / decommissioning<br />

phases.<br />

15.4.45 By making the site more accessible through the construction of access tracks, in particular<br />

two new link routes, the western end of the Carron Valley reservoir will become more<br />

popular.<br />

15.4.46 However, it is possible that some recreational and outdoor access users could be deterred<br />

from using access and recreational resources in the Carron Valley and the wider area if there<br />

is a possibility that their views would be compromised, although anecdotal evidence of<br />

previous FCS experience suggests this is unlikely.<br />

15.4.47 The mountain bike trails are recognised to be well used both locally and regionally (FCS data<br />

indicates some 80 % of all visits) and the sensitivity of this receptor is there<strong>for</strong>e considered to<br />

be high. However, given that the majority of these routes are within woodland to the south of<br />

the reservoir where views of the proposed wind farm would be screened by the tree cover,<br />

and that this user group tends to be more influenced by trail design and accessibility than<br />

views, it is considered unlikely that the proposed wind farm would deter bikers from using<br />

these trails. The evidence of the various surveys as identified above into the effect of wind<br />

farms on tourists supports this conclusion. The magnitude of this effect is there<strong>for</strong>e<br />

considered to be small, resulting in a slight negative effect.<br />

15.4.48 The Lochside Trail is also well used local recreational resource, and <strong>for</strong>ms part of the<br />

Stirlingshire Core Path network. The sensitivity of this receptor is there<strong>for</strong>e considered to be<br />

medium. From the Lochside Trail panoramic views across the Carron Valley towards the<br />

proposed wind farm would be experienced along the shores of the reservoir, including from<br />

the viewing area at the end of the trail. Although it is possible that some potential visitors<br />

may be deterred from using the Lochside Trail due to these views of the proposed wind farm,<br />

on the basis of the various surveys on the effects of wind farms on tourists identified above it<br />

is considered that the number of such access users would be small at worst. Furthermore, it<br />

should be recognised that although the view may be regarded by some access users as the<br />

primary reason <strong>for</strong> using the Lochside Trail, the journey and experiences other than the view<br />

(such as exercise, shared experience with family/ friends) are likely to play an important role<br />

in others’ enjoyment of the activity. These will not be affected by the presence of the<br />

proposed wind farm. The magnitude of effect is there<strong>for</strong>e considered to be small, resulting in<br />

a slight negative effect.<br />

15.4.49 The woodlands to the south of the Carron Valley Forest are used by hill walkers and contain<br />

several paths that <strong>for</strong>m part of the North Lanarkshire core path network. The sensitivity of this<br />

receptor is there<strong>for</strong>e considered to be medium. Within these woodlands, views from the<br />

footpaths into the Kilsyth Hills are determined by the age and density of tree cover and by the<br />

orientation of the paths. Views from the open summits within this woodland at Meikle Bin,<br />

Little Bin, Garrel Law and Tomtain are extensive, and all of the proposed turbines would be<br />

visible. The proposed turbines would also be visible from popular hillwalking skyline routes<br />

above Campsie Glen such as Lecket Hill, Holehead and Harthill. As outlined above,<br />

although it is possible that some potential hill walkers may be deterred from using these<br />

routes which provide access to the hill summits, on the basis of the various surveys on the<br />

effects of wind farms on tourists identified above it is considered that the number of such<br />

access users would be small at worst. The magnitude of effect is there<strong>for</strong>e considered to be<br />

small, resulting in a slight negative effect. Further south beyond the Carron Valley Forest,<br />

views of the proposed wind farm on the south side of the Kilsyth Hills would be obscured by<br />

the intervening topography.<br />

15.4.50 The Gargunnock and Touch Hills to the north of the Carron Valley are also well used by hill<br />

walkers and <strong>for</strong> grouse shooting and are there<strong>for</strong>e considered to be of medium sensitivity.<br />

From these hill ranges views would be restricted by Earl’s Hill and Hart Hill except on the<br />

upper slopes. Some of the proposed turbines may be also visible from the lower slopes of<br />

the Fintry Hills to the north west of the site. As outlined above, although it is possible that<br />

some potential hill walkers and field sports participants may be deterred from these areas, on<br />

Carron Valley Wind Farm<br />

the basis of the various surveys on the effects of wind farms on tourists identified above it is<br />

considered that the number of such hill walkers and field sports participants would be small at<br />

worst. In the case of field sports participants, it is considered to be the overall quality of the<br />

available shooting opportunity more than simply views that is likely to influence decision<br />

making. The magnitude of effect is there<strong>for</strong>e considered to be small, resulting in a slight<br />

negative effect.<br />

15.4.51 A number of other popular walking and cycling routes in the Carron Valley area may also<br />

experience views of the proposed wind farm along short durations of these routes, including<br />

the Tak Ma Doon Road and the minor road which links Stirling to the B818. None of these<br />

receptors are considered to be of more than low sensitivity. Given the short duration of the<br />

predicted views , it is considered unlikely that the proposed wind farm would deter walkers or<br />

cyclists from using these routes. The evidence of the various surveys as identified above into<br />

the effect of wind farms on tourists supports this conclusion. The magnitude of this effect is<br />

there<strong>for</strong>e considered to be small, resulting in a slight negative effect.<br />

15.4.52 Any views from hills further beyond, including those within the Loch Lomond and the<br />

Trossachs National Park, would be distant and would consequently be unlikely to deter<br />

walkers, recreational user groups or visitor numbers to the National Park.<br />

15.4.53 The Carron Valley is well used by local anglers. However, given that views experienced are<br />

unlikely to be the prime reason <strong>for</strong> fishing on the reservoir, the sensitivity of this receptor is<br />

considered to be low. Given the proximity to the proposed wind farm, all 15 turbines would<br />

be visible. As some anglers enjoyment could be affected by views of the proposed turbines,<br />

this could result in reduced numbers of anglers on the reservoir. However, on the basis of<br />

the various surveys as identified above, it is concluded that <strong>for</strong> the vast majority of anglers<br />

the visual presence of the wind farm would not be a major factor in their decision to fish there.<br />

The magnitude of this effect is there<strong>for</strong>e considered to be small.<br />

15.4.54 Any effects upon hydrology during the construction of the proposed wind farm which could<br />

have the potential to increase sediment load to the Carron Valley Reservoir and consequently<br />

reduce fish numbers will be mitigated through best practice and the mitigation measures<br />

identified in <strong>ES</strong> Chapter 13: Hydrology, Hydrogeology and Ground Conditions. The<br />

magnitude of this effect is there<strong>for</strong>e considered to be small.<br />

15.4.55 Overall the proposed wind farm is there<strong>for</strong>e anticipated to have a slight negative effect on the<br />

demand <strong>for</strong> angling on the Carron Valley Reservoir.<br />

15.4.56 In terms of other recreational activities, there are relatively few activities in the vicinity of the<br />

proposed wind farm <strong>for</strong> it to have a detrimental effect on the economy or on the levels of<br />

participation in these activities in the area in general.<br />

loss of <strong>for</strong>estry as a result of the footprints of the turbine bases, new access tracks, crane<br />

hardstandings, control area and the temporary construction areas will be achieved where<br />

possible by restocking additional areas in the main Carron Valley Forest and if possible within<br />

the Cairnoch Hill <strong>for</strong>est block. This compensatory restocking will balance the overall<br />

economic effects regarding <strong>for</strong>estry operations.<br />

Tourism and Recreation<br />

15.5.3 Minimisation of visual impacts has taken place through the site selection and design iteration<br />

process.<br />

15.5.4 Where possible, where <strong>for</strong>est access tracks are to be closed during construction works, a<br />

suitable diversion would be put in place along with the display of signage at each end of the<br />

track where the track is diverted. The signage would detail the track which is closed, the<br />

proposed alterative route and the duration of the closure.<br />

15.5.5 It is proposed that, once the wind farm is operational, PfR will contribute an agreed specified<br />

annual sum towards continued delivery of the FCS Forest Experience and Interpretation<br />

Plan. Through this mechanism, income from the operation of the proposed wind farm will be<br />

provided to FCS <strong>for</strong> use in developing access and recreational opportunities, as well as <strong>for</strong><br />

maintaining and enhancing existing access and recreational resources within the Carron<br />

Valley<br />

15.7 Cumulative Effects<br />

15.7.1 No potential <strong>for</strong> cumulative effects upon employment and the economy and land use due to<br />

the proposed wind farm and other existing wind farms, those which have planning permission<br />

and valid applications <strong>for</strong> wind farms in the area has been identified.<br />

15.7.2 On the basis of the various surveys as identified above into the effect of wind farms on<br />

tourists and recreational users, it is concluded that the number of tourists and recreational<br />

users who may be deterred by potential cumulative landscape and visual effects arising from<br />

the introduction of the proposed wind farm would be very small. For this reason, no potential<br />

<strong>for</strong> significant cumulative effects upon tourism and recreation have been identified.<br />

16.3 Schedule of Mitigation<br />

16.3.1 Mitigation measures have been identified in the technical assessments in this <strong>ES</strong> and will be implemented as described. The majority of mitigation<br />

has been built in to the design of the proposed wind farm. Other mitigation measures will involve use of best practice procedures in construction and<br />

site management. Proposed mitigation measures identified in the <strong>ES</strong> are summarised in Table 16.9 below, grouped according to the aspect of the<br />

development mitigation is designed to address. Full details of mitigation are provided within each individual technical chapter.<br />

Topic<br />

Traffic and Transport<br />

Noise<br />

Key Mitigation and Enhancement Measures<br />

The traffic and trasnsport assessments demonstrate that there is no requirement <strong>for</strong> any mitigation measures. However, a Traffic<br />

Management Plan (‘TMP’) will be drawn up and agreed with the Road Authority as an enhancement measure prior to construction. The<br />

TMP will provide the following in<strong>for</strong>mation:<br />

• approved access routes and any necessary restrictions;<br />

• temporary signage in the vicinity of the proposed wind farm warning of construction traffic;<br />

• temporary signage warning other users of abnormal load turbine movements;<br />

• arrangements with Police <strong>for</strong> escort of abnormal loads;<br />

• ground preparation, including protection of services;<br />

• arrangements <strong>for</strong> road maintenance and cleaning;<br />

• timing of deliveries – construction hours will be outside of peak traffic hours, subject to agreement with the road authorities; and<br />

• wheel cleaning arrangements and regular road sweeping runs.<br />

Abnormal loads will be escorted, from the port of entry (currently envisaged being Grangemouth) with timings agreed with the road<br />

authorities and police as appropriate.<br />

These measures will assist in minimising any environmental effects associated with the construction traffic generated by the proposed<br />

wind farm.<br />

In order to further reduce traffic effects associated with the construction of the proposed wind farm, construction personnel will be<br />

encouraged to car-share where practicable.<br />

Construction Phase<br />

A Noise and Vibration Management Plan will be incorporated into the HSEMS (see Appendix 4.4) that will identify Best Practicable Means<br />

(as defined in the Control of Pollution Act (CoPA) (1974)), in the <strong>for</strong>m of construction best practice measures, to appropriately and<br />

Assessment<br />

Cultural Heritage and Archaeology<br />

Key Mitigation and Enhancement Measures<br />

effectively manage noise and vibration from construction activities. Typical mitigation measures may include:<br />

• Agreed core hours of noisy working;<br />

• Commitments to using well maintained, low noise emission plant;<br />

• Switching off plant when not in use;<br />

• Considerate management and working to minimise noise impacts, e.g. low haul road speed; and<br />

• Contact details <strong>for</strong> site personnel in case of noise issues.<br />

Operational Phase<br />

No mitigation measures are required.<br />

Decommissioning Phase<br />

A noise assessment would be required prior to the commencement of decommissioning works and appropriate noise control measures at<br />

the time identified and agreed with the relevant authority.<br />

The majority of landscape and visual mitigation has, been ‘built in’ to the design of the proposed wind farm through the design process of<br />

its layout, which in principal, aimed to avoid and reduce the potential <strong>for</strong> adverse landscape and visual effects whilst achieving the most<br />

suitable wind farm layout <strong>for</strong> the particular site location. No further landscape mitigation would be proposed.<br />

The most significant impacts of this proposed wind farm on the historic environment is its effect on the setting of Sir John de Graham’s<br />

Castle and thus the mitigation approach has been focussed on diminishing and offsetting these effects.<br />

The proposed wind farm layout has gone through several design iterations, including the complete removal of one turbine. The results of<br />

these changes has increased the distance of the nearest turbine to Sir John de Graham’s Castle from 200 m to 480 m. In terms of<br />

turbines that affect views from the castle looking along the valley the nearest turbine will now be more than 1 km away.<br />

Removal of an area of non-native plantation that currently lies between the Castle and Carron Valley Reservoir with th aim of significantly<br />

opening up views both from and towards the castle, going some way to restoring its position within the wider local landscape that has<br />

been obscured in recent decades.<br />

For the longer-term management of the Caslte by the FCS the following is proposed to take tackle concerns expressed about the use of<br />

the site <strong>for</strong> camping, involving removal of stones from the ruins, the burning of camp fires within the scheduled area, as well as evidence<br />

<strong>for</strong> illicit metal detecting on the site and a lack of in<strong>for</strong>mation availble to the public about the significance of the site<br />

• An aerial photographic and earthworks survey of the Castle and associated features;<br />

• A geophysical survey of the motte and the area to the north-east;<br />

• Targeted sampling of the sedimentary sequence in the motte to retrieve i) dating evidence <strong>for</strong> the period of its use and ii) an<br />

• A web-page on the FCS website providing public access to further in<strong>for</strong>mation on this work and its results.<br />

.<br />

Pre-Construction Mitigation<br />

Within 6 months prior to commencement of the works on site, pre-construction surveys based on existing data <strong>for</strong> protected species will<br />

be carried out to check <strong>for</strong> changes in baseline conditions. This will enable any refinements to be made (if necessary) through micrositing<br />

and/or adjustments to the construction programme to take into account any up-dated distributions or presence of species.<br />

Construction Mitigation<br />

All relevant mitigation measures will be implemented through the project Health, Safety and Environmental Management System<br />

(HSEMS) (HSEMS, see Chapter 4, Appendix 4.4), which will be prepared in consultation with, and to the satisfaction of Stirling Council,<br />

SEPA and SNH. These will detail measures such as:<br />

• Application of SEPA’ Pollution Prevention Guidance (PPG’s) delimitation of working areas to minimise damage to habitats;<br />

• A minimum 50 m buffer will be maintained, where possible, between working areas, machinery and watercourses in all areas<br />

except at watercourse crossing points;<br />

• Pollution prevention measures will be installed and maintained as appropriate, including silt interception traps, settling lagoons or<br />

mobile silt-trapping units (such as Siltbusters or equivalent device), as well as installation of splash boards at watercourse<br />

crossing points to prevent contamination from track run-off;<br />

• Chemicals, oils and hazardous materials will be stored in designated areas securely at a minimum distance of 50 m from the<br />

watercourses;<br />

• Spillage contingency kits will be provided in all site vehicles and there will be daily checks <strong>for</strong> oil and fuel leaks;<br />

• Application of best practice in relation to the removal and storage of vegetation turfs and soils to ensure effective reinstatement<br />

of vegetation wherever possible;<br />

• Application of best practice techniques of track and turbine base construction to ensure that drainage patterns and water quality<br />

within the study area are maintained;<br />

• Application of best practice to ensure materials appropriate to site geology are used in construction activities; and<br />

• Timing of works to avoid periods of heavy rain when the risk of fine sediment being transported from earth works is significantly<br />

increased.<br />

Pollution incident response and drainage management measures will be prepared as a part of the HSEMS to minimise potential pollution<br />

effects.<br />

An Ecological Clerk of Works (ECoW) will be present on site to oversee enabling works and construction. Part of the ECoW’s duties will<br />

be to provide pre-construction and pre-felling checks <strong>for</strong> all European Protected Species, water voles, badgers, pine marten, red squirrel<br />

and reptiles.<br />

Best practice measures <strong>for</strong> minimising the potential <strong>for</strong> disturbance and injury to protected species will be employed. These will include:<br />

• Covering all trenches, trial pits, excavation and pipelines to prevent animals entering these holes;<br />

• Provision of a method of escape (e.g. a plank) where such excavations cannot be closed or filled on a nightly basis; and<br />

• Vehicle speeds will be restricted across site in order to minimise the risk of collision with animals.<br />

Removal of the most suitable terrestrial habitats <strong>for</strong> reptiles to be affected by construction activities will be planned to take place outside<br />

of the hibernation periods <strong>for</strong> these species and supervised by the ECoW who will halt works where necessary to allow reptiles to move<br />

away from the affected areas.<br />

Where water crossings are to be upgraded, these will be designed so as to not present any barriers to the passage of migratory fish or<br />

other fauna.<br />

Water quality baseline surveys and subsequent monitoring during the construction phase of the development will encompass chemical<br />

testing, daily visual inspections of waterways by the ECoW, electrofishing surveys and macroinvertebrate sampling to ensure water<br />

quality is maintained.<br />

Where practicable, reinstatement of habitats will be undertaken around infrastructure. This will be carried out as the work front<br />

progresses, or as soon as is practical after the completion of the works. The methods of this will be detailed within the HSEMS.<br />

Mitigation measures specific to the protection of badgers on the site are detailed further within Chapter 11, Appendix 11.7 (confidential).<br />

Operation Mitigation<br />

The vehicle speed restrictions stipulated during the construction phase will continue during the operation of the wind farm.<br />

Vehicles coming on site will be regularly checked <strong>for</strong> oil leaks to avoid risk of pollution. Spillage kits will be available on the wind farm<br />

site. Best practice methodologies (outlined in the HSEMS) will be employed during any maintenance works to ensure the prevention of<br />

any pollution to habitats or watercourses, along with implementation of the site pollution incident response plan and drainage<br />

management plan.<br />

A method statement <strong>for</strong> responding to bat corpses should be included in the site operation procedures. Incidental records of dead bats<br />

should be noted and taken into account in the operation of the site. Consideration should then be given to whether it might be<br />

appropriate to undertake additional survey or monitoring, such as corpse searches.<br />

Key Mitigation and Enhancement Measures<br />

In line with SNH accepted Natural England guidance, all habitats within 50 m of the turbines blade tips should be maintained in state<br />

which offers poor <strong>for</strong>aging <strong>for</strong> bats.<br />

Decommissioning Mitigation<br />

Best practice measures, as described in the construction stage, will be followed. New guidance available at the decommissioning phase<br />

will be adopted if appropriate.<br />

Ornithology<br />

Best practice regarding breeding birds<br />

There is a need to follow best practice during the construction of the development to ensure compliance with the legislation concerning<br />

disturbance to breeding birds.<br />

Legislative protection<br />

Best practice will be necessary to reduce the possibility of illegal damage, destruction or disturbance to occupied bird nests during the<br />

construction phase (or during any maintenance work in the operational phase). Three best practice measures outlined below will be<br />

adopted: the use of an ECoW, and the timing of construction activities and visual deterrents. There will be a clear line of responsibility <strong>for</strong><br />

ensuring these measures are adhered to, which will be specified in the HSEMS to which the appointed contractor will be required to<br />

adhere (see Chapter 4, Appendix 4.4).<br />

Ecological Clerk of Works<br />

A suitably experienced ECoW will carry out pre-construction surveys and locate any active nests close to construction works shortly<br />

be<strong>for</strong>e these commence.<br />

Timing of construction activities and visual deterrents<br />

If feasible, site clearance and construction activities will be timed to take place outside of the main breeding season so as to avoid nest<br />

destruction and disturbance to breeding birds<br />

Where working in the breeding season can be avoided, activities will aim to commence be<strong>for</strong>e mid-March wherever possible. By timing<br />

construction activities to start be<strong>for</strong>e the breeding season, birds will have an opportunity to take potential disturbance into account in the<br />

process of selecting a nest site, and those birds with a choice of nest sites may select an alternative nest site <strong>for</strong> that season.<br />

In areas where work is unavoidable during the breeding season, deterrents may be placed within a restricted area well in advance so that<br />

birds will not choose to nest within that locality. Examples of deterrence include using bird scarers, reflective tape or ribbons on posts or<br />

physical removal of habitat.<br />

Where applicapble, construction activities in close proximity to breeding birds would be limited to certain periods of the day, such as<br />

avoiding periods two hours be<strong>for</strong>e and after dawn and dusk where species such as barn owl are most active.<br />

Key Mitigation and Enhancement Measures<br />

Pre-construction surveys<br />

Following the implementation of any appropriate deterrent devices prior to the breeding season, surveys will be undertaken by an ECoW<br />

or other suitably-qualified person, to locate nesting birds and lekking black grouse in the vicinity of construction works to ensure that none<br />

are disturbed.<br />

Any active nests found will be cordoned off to a suitable distance <strong>for</strong> the species concerned (up to 20 m <strong>for</strong> woodland and scrub nesters<br />

and up to 50 m <strong>for</strong> open-ground nesting species) and construction operations delayed within the cordon until the young have fledged and<br />

the nest becomes vacant. This will be confirmed by the ECoW prior to the recommencement of construction.<br />

Larger buffer distances will be used to avoid spatial overlap of construction activities and breeding attempts of Schedule 1 and/or Annex I<br />

species, which are subject to additional protection relating to disturbance during the breeding season.<br />

If nest building activity of Schedule 1 species is seen within a cordoned area, continued deterrence would constitute disturbance and is an<br />

offence under the Wildlife and Countryside Act, so would be stopped immediately. In this case, and also if birds are nesting outside of<br />

controlled areas but in the opinion of the ECoW within possible disturbance zones, the work will either be re-scheduled or the nest site<br />

cordoned-off and destruction prevented.<br />

In such situations, SNH recommends that pre-construction breeding bird surveys take place, with works then being programmed to avoid<br />

disturbance. A number of surveys may there<strong>for</strong>e be required as construction progresses through the site.<br />

Mitigation and Enhancement <strong>for</strong> Osprey and Barn Owl<br />

Specific objectives will be made <strong>for</strong> osprey if required. In conjunction with the Central Scotland Raptor Study Group, artificial nests and/or<br />

nesting plat<strong>for</strong>ms would be proposed within suitable habitat in the local area, beyond recognised disturbance-displacement zones from<br />

the proposed development or other projects, and within areas that are likely to facilitate the continued expansion of the central Scotland<br />

population (e.g. on the shore-side of Carron Valley Reservoir or in the <strong>for</strong>estry to the south). Site selection and construction will follow<br />

relevant best practice guidelines (e.g. http://www.roydennis.org/osprey/index.asp?id=90). The aim will be to help continue the upward<br />

population trend and range expansion of osprey numbers in central Scotland.<br />

Additional barn owl boxes will be placed in suitable habitat, away from the effects of the wind farm, if any current sites are to be disturbed.<br />

This will help reverse the habitat loss and fragmentation <strong>for</strong> this species of conservation concern.<br />

In conjunction with creation of new nest sites, <strong>for</strong>est clearance undertaken by FCS in advance of the wind farm construction programme<br />

will also be undertaken with ospreys in mind. Surveys will be conducted prior to wind farm construction to determine the remaining<br />

locations of any potential nesting trees within displacement or high collision risk zones on Cairnoch Hill, and these will be felled or the<br />

crowns removed during the non-breeding season. The extent and suitability of this measure will be determined by the ECoW in<br />

conjunction with FCS and will include discussions with SNH and the Central Scotland Raptor Study Group if considered appropriate.<br />

Site Pollution Control<br />

A Health, Safety and Environmental Management System (HSEMS), including pollution prevention measures, specifically aimed at the<br />

water environment, and construction method statements, will be in place during construction, operation and decommissioning. An outline<br />

structure of the document is presented in Chapter 4, Appendix 4.4. The HSEMS will include the mitigation measures to be implemented<br />

to prevent or minimise effects on the surface and groundwater environment, and will also include a bespoke Incident Response Plan.<br />

The timing of the works will be planned to avoid construction of tracks and other potentially polluting activities during periods of high<br />

rainfall as far as reasonably practicable.<br />

The HSEMS will address the following issues:<br />

• Storage – all equipment, materials and chemicals will be stored in designated locations at an appropriate distance from<br />

watercourses. Chemical, fuel and oil stores will be sited on impervious bases within a secured bund in accordance with relevant<br />

guidance and best practice.<br />

• Vehicles and Refuelling – standing machinery will have drip trays placed underneath to prevent oil and fuel leaks causing<br />

pollution. Drip trays will have minimum capacity of 110% of the fuel tank. Where practicable, refuelling of vehicles and<br />

machinery will be carried out in one or potentially two designated areas, on an impermeable surface, and well away from any<br />

watercourse. Drip trays will also be used during refuelling and spill kits will be stored in vehicles on site, at designated refuelling<br />

areas and where chemicals are stored. Site staff will be training in their use.<br />

• Maintenance – where vehicles or plant require maintenance, this will be undertaken in a designated area within the construction<br />

compound where reasonably practicable, unless vehicles have broken down necessitating maintenance at the point of<br />

breakdown, where special precautions will be taken.<br />

• Welfare Facilities – on-site welfare facilities will be adequately designed and maintained to ensure that all wastewater and<br />

sewage is disposed of appropriately. This may take the <strong>for</strong>m of an on-site septic tank with soakaway, or offsite disposal<br />

depending on the suitability of the site <strong>for</strong> a soakaway and prior agreement with SEPA.<br />

• Cement and Concrete – fresh concrete and cement are very alkaline and corrosive, and can be lethal to aquatic life. The use of<br />

wet concrete in and around watercourses will be avoided or, where essential, carefully controlled by provision of an agreed<br />

construction method statement prior to construction.<br />

• Contingency Plans – will ensure that emergency equipment will be available on-site i.e. spill kits and absorbent materials,<br />

addition pumps, in<strong>for</strong>mation on where and from whom to seek advice, and who should be in<strong>for</strong>med in the event of a pollution<br />

incident; and<br />

• Inspections – All mitigation measures put in place, e.g. silt traps and sediment settlement tanks, will be inspected regularly and<br />

suitably maintained to ensure they remain fully operational and effective. Where failures or shortfalls within mitigation measures<br />

are noted, these will be recorded, suitable action identified and undertaken within a suitable timeframe.<br />

Waste Management<br />

The production of waste will be minimised throughout the works, including wastes from peat and this has been taken into account in the<br />

design process to avoid where possible areas of deeper peat. Where waste is generated, this will be reused and recycled where<br />

possible.<br />

A Site Waste Management Plan (SWMP) will be produced to address the management of waste streams. The SWMP will address the<br />

• Appropriate Storage and Disposal of Waste taking account of stability and pollution prevention;<br />

• Management of peat, Superficial Deposits and Bedrock;<br />

• Re-use of peat where possible on site (Consultation with SEPA will be required <strong>for</strong> any intended re-use of peat on the site.);<br />

• Management of Waste Oils;<br />

• Recommendations <strong>for</strong> Inspection and Maintenance.<br />

Environmental Monitoring<br />

A groundwater and surface water monitoring programme will be implemented to obtain baseline data, as well as data during construction<br />

works. The scope will be agreed with SEPA and Stirling Council prior to implementation.<br />

Surface Water<br />

A surface water monitoring network will be established a minimum of six months prior to construction works.<br />

In addition to surface water monitoring, regular visual inspection of surface water management features such as drainage pipes and<br />

receiving watercourses will be carried out in order to establish whether there are increased levels of suspended sediment, erosion or<br />

deposition. It is likely that there will be an ongoing need to maintain these structures, <strong>for</strong> example by the removal of debris, to ensure<br />

they continue to function as designed.<br />

Regular visual inspection of watercourses will also be required during construction and decommissioning stages, particularly during<br />

periods of high rainfall but also during low flow conditions, in order to establish that levels of suspended solids have not been significantly<br />

increased by on-site activities.<br />

Monitoring Ground Movement<br />

As the access tracks are being constructed, the appearance of the track and surrounding land will be monitored <strong>for</strong> increased rate of<br />

sinking or tilting or a rise in water levels.<br />

During and immediately after periods of heavy rainfall, earthmoving activities will be reviewed with temporary restrictions where<br />

necessary.<br />

Drainage<br />

The implementation of Sustainable Drainage Systems (SuDS) as opposed to conventional drainage systems on the proposed wind farm<br />

will provide several benefits by:<br />

• Reducing peak flows to watercourses and potentially reducing risk of flooding downstream;<br />

Summary of Effects and Mitigation


Carron Valley Wind Farm<br />

Topic<br />

Key Mitigation and Enhancement Measures<br />

• Reducing the volumes and frequency of water flowing directly to watercourses;<br />

• Improving water quality by removing pollutants;<br />

• Reducing potable water demand through rainwater harvesting;<br />

• Replicating natural drainage patterns, including the recharge of groundwater so that local base flows are maintained.<br />

Where appropriate, SuDS principles have been incorporated into the water management methods discussed in the following sections.<br />

Where there is a high risk of oil contamination identified by the appointed construction contractor, and subsequently by the site operator, it<br />

may be appropriate to integrate an oil separator into any SuDS measures. The implementation of the type of SuDS measures will be<br />

dependent upon detailed site and hydrological investigations<br />

Abstractions<br />

A surface water abstraction will be required <strong>for</strong> the concrete batching and washing of plant. It is estimated that approximately 30 m 3 of<br />

water will be required per day. To minimise downstream impacts during periods of low flows, a proportion of water will be left in the<br />

stream <strong>for</strong> water quality purposes, fish and other fauna. On-site water storage facilities will also be provided to create a water supply<br />

buffer <strong>for</strong> periods of high demand or prolonged low flows.<br />

Geotechnical Design<br />

Detailed geotechnical design will be undertaken <strong>for</strong> each turbine location, access track, hard standing areas and the construction<br />

compound. This will be based on the location-specific mechanical characteristics of the ground conditions and the morphology of the<br />

underlying strata (i.e. superficial deposits or bedrock). Further targeted ground investigation will there<strong>for</strong>e in<strong>for</strong>m a detailed design<br />

utilising current and location specific geotechnical data.<br />

Peat Stability Risk<br />

The Peat Stability Risk Assessment report included in Chapter 13, Appendix 13.2 has identified a low to medium baseline qualitative risk<br />

of peat stability <strong>for</strong> the site. The semi-quantitative assessment has identified that under the loaded scenario, the Factor of Safety (FOS)<br />

would be


Carron Valley Wind Farm<br />

Topic<br />

Key Mitigation and Enhancement Measures<br />

Turbine Foundations<br />

Bunds will be placed around turbine foundations to direct any overland flow away from open excavations. Drainage ditches will be<br />

constructed to attenuate and convey the runoff away from the excavation be<strong>for</strong>e being treated in a settlement lagoon.<br />

Water derived from all dewatering activities during the construction phase will be treated via settlement lagoons be<strong>for</strong>e being discharged<br />

to groundwater or surface water.<br />

Treated water can also be discharged onto vegetated surfaces and directed away from watercourses and drainage ditches to avoid direct<br />

entry into watercourses. For discharge onto rough grasslands to be effective the discharge must be spread efficiently.<br />

Turbine Hardstandings<br />

Turbine hardstandings will be designed in such a way that surface water will infiltrate through the relatively permeable surface or will<br />

discharge into the associated road drainage .This means that overall runoff rates remain close to greenfield conditions.<br />

Site Tracks<br />

The construction depths of new tracks will vary depending on the ground conditions encountered. A cut track construction method will be<br />

used on firm granular <strong>for</strong>mation surface and existing tracks will be used and upgraded between the site entrance and construction<br />

compound.<br />

The tracks will be constructed with sufficient camber or crossfall to minimise ponding of surface water on the track surface. Any surface<br />

water not infiltrating through the access track base will be directed into infiltration trenches and/or drainage ditches prior to being<br />

discharged into settlement ponds. These SuDS measures will treat and attenuate the runoff be<strong>for</strong>e discharging back into the natural<br />

drainage network. Infiltration trenches and drainage ditches will be constructed with outlets at frequent intervals to limit the volume of<br />

water collected in a single channel, thus reducing the erosive potential and allowing runoff from upslope of a track to pass underneath the<br />

access track. These measures will minimise the risk of erosion of the track surface and the subsequent risk of sedimentation.<br />

Where the access tracks are constructed across natural areas of drainage such as flushes and springs, drainage measures in the <strong>for</strong>m of<br />

drainage pipes will be installed under the access track to allow the run-off to continue to follow its natural course. Where required existing<br />

field drains will be reconfigured to ensure an effective drainage of the area and to prevent surface water ponding behind tracks.<br />

In general, the SuDS proposed as part of the access tracks and other infrastructure are predicted to reduce any potential effect on runoff<br />

characteristics to baseline conditions. This is due to:<br />

The sparse distribution of the proposed infrastructure, without large continuous impermeable areas. The total surface area of proposed<br />

infrastructure does not exceed 1.3 % in any sub-catchment.<br />

Access tracks and hard standing areas will be constructed using graded bedrock allowing some surface water infiltration and drainage<br />

through adjacent soils.<br />

Where drainage ditches are required, outfalls will be distributed along the ditches to minimise runoff rates and to allow infiltrate into<br />

adjacent soils.<br />

Topic<br />

Key Mitigation and Enhancement Measures<br />

Where tracks are situated near deep peat, drainage systems will be adapted to ensure that the water table in the adjacent peat is not<br />

affected or only affected over a short distance. For example, drainage ditches along the track will be as shallow as possible sufficient to<br />

drain rainfall from the track surface and to prevent runoff flooding the track. The track surface will be near the adjacent peat surface and<br />

cross-drains will be installed at or just below the track surface. These measures will ensure that runoff within the upper peat layer<br />

(acrotelm) is not blocked by the track. The track base will be constructed using suitably permeable graded material such that the slow<br />

movement of water in the deeper peat layers is Negligiblely affected by the track.<br />

Watercourse Crossings<br />

The proposed wind farm access tracks require upgrading, which will require all but one of the existing water crossings to be upgraded.<br />

Upgrading of the existing water crossings is considered to be the best environmental option, in comparison with replacing the existing<br />

crossings completely.<br />

Location of the new site access tracks required <strong>for</strong> the development has been minimised to avoid the need <strong>for</strong> water crossings where<br />

possible. As such, no additional water crossing will be required.<br />

Extended crossing structures will not <strong>for</strong>m a barrier to aquatic fauna, and will be designed and constructed with respect to relevant<br />

guidance and best practice.<br />

Where access tracks cross artificial drainage ditches, simple pipe structures will be installed. The pipe invert levels will be installed<br />

slightly below upstream and downstream bed levels to ensure that barriers <strong>for</strong> fish passage and sediment transport are minimised.<br />

Watercourses, crossings and drainage ditches will be inspected and cleared regularly to prevent blockages and remove the risk of<br />

flooding throughout the construction and operational life of the wind farm.<br />

On-Site Buildings<br />

On-site welfare facilities will be adequately designed and maintained to ensure all wastewater and sewage is disposed of appropriately.<br />

Rainfall on roofs will be collected in a rainwater tank <strong>for</strong> re-use within the building. Any excess rainwater will be discharged to<br />

groundwater or surface water.<br />

Cables<br />

Where cables are required to be buried, the following mitigation shall be put in place:<br />

• Excavations <strong>for</strong> trenches will be of minimal size necessary to undertake works;<br />

• Cable trenches will be dug, cables laid and filled in sections to minimise the areas of active excavation open at any one time;<br />

and<br />

• Bunds will be placed along the route of the buried cable route to prevent the creation of a preferential pathway <strong>for</strong> groundwater<br />

arising along the path of the cable.<br />

Key Mitigation and Enhancement Measures<br />

If concrete batching is to be undertaken on site, it should be undertaken only in a designated area, away from watercourses, private<br />

water supplies, wetland areas and in an impermeable area.<br />

Washout from concrete batching and drainage from the concrete batching area will be collected in a separate drainage system and<br />

treated be<strong>for</strong>e being discharged.<br />

When concrete is being poured shutters will be used and, if being poured into an excavation, only into an area free from standing water.<br />

Pumps should be used to keep excavations dry if required.<br />

Concrete batching and pouring will not be undertaken during adverse weather.<br />

Traffic<br />

Site traffic will be kept to clearly designated tracks, as per the site traffic management plan.<br />

Barriers and/or netting will be used to prevent vehicle movements in sensitive areas.<br />

Where vehicle movements are required to take place off-track, e.g. on soft ground during construction phase, these will be limited to the<br />

absolute minimum and where excessive off-track vehicle movements are required, temporary tracks (e.g. geotextile overlain with<br />

aggregate) or peat-boards should be used to prevent damage to the soil and creation of sediment laden runoff.<br />

If there is a requirement to wash vehicles on-site or as they enter, or leave site, this activity should be undertaken in a designated area<br />

that bunded to prevent uncontrolled runoff or release of water from the washing process. All water and runoff arising from vehicle washing<br />

will be controlled and treated prior to discharge back into any watercourse.<br />

As no inhabited properties were identified within the zone of potential shadow flicker, no significant effects have been identified and thus<br />

no mitigation measures are required.<br />

Employment and the Economy<br />

PfR will seek to use local labour where possible to maximise the benefits to the local economy.<br />

Land Use<br />

All <strong>for</strong>estry required to be felled <strong>for</strong> the proposed wind farm will be removed in accordance with the Scottish Government’s Control of<br />

Woodland Removal Policy. Mitigation <strong>for</strong> the direct loss of <strong>for</strong>estry as a result of the footprints of the turbine bases, new access tracks,<br />

crane hardstandings, control area and the temporary construction areas will be achieved where possible by restocking additional areas in<br />

the main Carron Valley Forest and if possible within the Cairnoch Hill <strong>for</strong>est block. This compensatory restocking will balance the overall<br />

economic impacts regarding <strong>for</strong>estry operations.<br />

Minimisation of visual impacts has taken place through the site selection and design iteration process.<br />

Where possible, where <strong>for</strong>est access tracks are to be closed during construction works, a suitable diversion would be put in place along<br />

proposed alterative route and the duration of the closure.<br />

It is proposed that, once the wind farm is operational, PfR will contribute an agreed specified sum towards continued delivery of the FCS<br />

Forest Experience and Interpretation Plan. Through this mechanism, income from the operation of the proposed wind farm will be<br />

9 Landscape and Visual<br />

9.1 Introduction and Overview<br />

9.1.1 This chapter identifies the existing character and features of the landscape, as well as the<br />

existing visual resources of the surrounding area. It details the changes that may result as a<br />

consequence of the proposed wind farm and considers the potential significance of effects<br />

arising as a result.<br />

9.1.2 The key elements of the proposed wind farm likely to result in effects on the receiving<br />

landscape include construction and operation of wind turbines and associated structures,<br />

buildings and access tracks and the felling of trees on Forestry Commission Scotland (FCS)<br />

land. These elements may also affect sensitive visual receptors in the area.<br />

9.1.3 There is a clear distinction between effects on landscape resources and visual effects.<br />

Landscape receptors include physical elements, features and characteristics, or areas<br />

defined by a designation, that may be affected by the proposal. Visual receptors include the<br />

public or community at large, residents and visitors to the area. The effect on the setting of<br />

historic monuments (including Listed Buildings) is considered in Chapter 10: Cultural Heritage<br />

and Archaeology, of this Environmental <strong>Statement</strong> (<strong>ES</strong>).<br />

9.1.4 The significance of effect on a receptor can be established by identifying the sensitivity of the<br />

receptor to change, in combination with the magnitude of change that would occur as a result<br />

of the proposed wind farm. Within this chapter effects are defined as 'significant' in EIA<br />

terms.<br />

9.1.5 A description of the proposed wind farm is provided in Chapter 4: Description of the Proposed<br />

Development of this <strong>ES</strong>.<br />

9.1.6 The planning policy overview <strong>for</strong> the proposed wind farm is set out in Chapter 5: Planning<br />

Policy Overview of the <strong>ES</strong>. Relevant landscape and visual guidance and policy are detailed<br />

below in Section 9.2.<br />

9.2 Methodology<br />

Study Area<br />

9.2.1 The study area <strong>for</strong> the proposed wind farm is defined by a 35 km radius from the closest wind<br />

turbine (see Figure 9.1), as recommended <strong>for</strong> wind turbines over 100 m, as set out in ‘Visual<br />

Representation of Windfarms’, Good Practice Guidance, Scottish Natural Heritage (2007). It<br />

measures approximately 12,100 square kilometres incorporating several council regions<br />

within Scotland. Although the proposals would theoretically be visible over greater distances<br />

in periods of very good visibility, it was considered unnecessary to extend the study further<br />

because at 35 km the limit (acuity) of the human eye is being approached.<br />

Consultation<br />

9.2.2 Be<strong>for</strong>e the submission of the proposed wind farm application, consultation was carried out<br />

with Stirling Council (SC), North Lanarkshire Council (NLK), Falkirk Council (FK), East<br />

Dunbartonshire Council (EDC), Scottish Natural Heritage (SNH) and Loch Lomond and the<br />

Trossachs National Park Authority (LLTNPA) in order to determine sensitive receptors and<br />

representative viewpoints.<br />

9.2.3 A plan within the Scoping Report of September 2011 illustrating a preliminary zone of<br />

theoretical visibility (ZTV) based on a 126 m blade tip height <strong>for</strong> the 16 turbine scheme and<br />

20 candidate viewpoint locations provided the basis <strong>for</strong> the consultation. SNH suggested new<br />

viewpoints at Meikle Bin, Conic Hill and Falkirk Wheel upper basin. LLTNPA suggested the<br />

David Marshall Lodge as a potential alternative to the Mentieth Hills viewpoint. The NPA also<br />

recommended views from the following ‘gateway routes’ <strong>for</strong> consideration within the <strong>ES</strong>; the<br />

A811 from Balloch, the A81 from Aberfoyle, the A82 Alexandria to Luss. The following<br />

sequential receptors were suggested; the A811 from Stirling to Balfron Station, the A873<br />

Stirling to Aberfoyle, the A81 Aberfoyle to Balfron Station, the A809/A81 from Glasgow to<br />

Balfron Station, the West Highland Way from Balmaha to Conic Hill, cyclists on the NCR7<br />

from Balloch to Aberfoyle and walkers using the Rob Roy Way parallel to this. The Councils<br />

were content with the choice of viewpoints.<br />

9.2.4 As part of the consultation process Viewpoint 5: minor road from Kilsyth was discarded in<br />

favour of a location at Tomtain Hill which is a local high point in the landscape. Viewpoint 17:<br />

Antonine Wall was also discarded in favour of a new viewpoint at Falkirk Wheel, as no<br />

significant views could be identified within the ZTV. Following site visits and the preparation<br />

of wirelines this viewpoint was also discarded as no view of the proposals would be possible.<br />

9.2.5 A final list of 22 candidate viewpoints was established following the consultation process. The<br />

locations were visited and photography undertaken to establish their relevance within the<br />

assessment process.<br />

9.2.6 Other specific issues raised by SNH include;<br />

• The need to consider the Stirling Landscape Capacity Study.<br />

• Consideration should be given during the design phase to existing, consented and<br />

planned wind farms in the vicinity.<br />

9.2.7 This LVIA addresses the main issues of concern raised by SC, as determining authority, and<br />

statutory consultees during the pre-application consultations.<br />

9.2.8 There has been ongoing public consultation on the emerging design of the proposed wind<br />

farm through public exhibitions, local meetings and meetings with individual local residents.<br />

Published Guidance<br />

9.2.9 As a matter of best practice, this assessment has been undertaken based on published<br />

guidance on landscape and visual assessment. This includes:<br />

• Landscape Institute and Institute of Environmental Management and Assessment<br />

Positive and Negative Effects<br />

9.2.12 Wind energy development, wherever it occurs, is usually visible, i.e. wind farms require an<br />

exposed position, generally an upland location or, alternatively, a large area of generally level<br />

and open landscape. It also tends to have a characterising effect upon the landscape,<br />

depending upon the scale of the proposal and the character of the environment into which it<br />

is placed. The proposed wind farm would have the following general attributes typical of most<br />

wind farms: engineered, large scale, simple in <strong>for</strong>m, smooth texture, monochrome/muted<br />

colour and strong vertical <strong>for</strong>m. Responses by people to wind farms can vary from ‘beautiful’<br />

to ‘offensive’ with respondents perceiving wind turbines as potentially rhythmic, unusual, safe,<br />

interesting, invigorating, majestic and spiritual on the one hand and degrading, jarring,<br />

overbearing, industrial, clashing and ugly on the other. Wind energy development thus gives<br />

rise to a spectrum of responses from individuals and organisations who perceive its effects<br />

ranging from strongly adverse to strongly positive.<br />

9.2.13 The likely significant effects should be described covering type (i.e. direct, indirect or<br />

cumulative), temporal nature (short, medium and long term, permanent or temporary), and<br />

valency (positive and negative or adverse). Accordingly, judgements as to valency of the<br />

effect should be given and justified in an explicit and transparent manner since they are<br />

inevitably subjective.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

9.2.14 The heading ‘valency’, originally used in the Durham County Council Impact Assessment<br />

Matrices (unpublished, 1996) but now much more widely recognised, is an important one and<br />

provides scope to recognise that change of whatever type and scale within a landscape can<br />

be viewed positively or negatively by different individuals. For the purposes of this<br />

assessment effects have been defined based on a ‘worst case scenario’ i.e. an individual<br />

who may perceive the wind farm as a negative addition to the landscape or view. Effects are<br />

there<strong>for</strong>e defined as adverse throughout the assessment. An individual who perceives wind<br />

farms as a positive addition to the landscape or view may consider the same effects to be<br />

beneficial or neutral in nature. Further definition of valency and public attitudes to wind<br />

energy development can be found at Appendix 9.1.<br />

Baseline In<strong>for</strong>mation (Baseline & Cumulative Effects)<br />

9.2.15 The baseline <strong>for</strong> EIA purposes is taken as being the existing situation at submission of the<br />

application, including operational wind farms. The site is located within an area of commercial<br />

<strong>for</strong>estry managed by FCS. The ongoing management of this <strong>for</strong>est is defined within the FDP.<br />

Management operations include felling and replanting of trees progressively within the site<br />

which changes the baseline situation. However, the changes are considered to be on a<br />

relatively small scale and would not justify the identification of an interim future baseline<br />

situation, in 2015 when construction of the scheme would commence, against which the<br />

proposal would be assessed. The baseline includes any other commercial wind farms that<br />

are either operational, consented, or <strong>for</strong>mally in the planning system at the time of<br />

submission of the application. However, those <strong>for</strong> which a planning application has been<br />

submitted and has since been withdrawn without any assurances that a revised or modified<br />

application is known to be pending are not included in the assessment.<br />

9.2.16 The cumulative effects of two or more wind farm schemes should consider the effect of all<br />

those wind farms within 70 km (i.e. twice the 35 km study area <strong>for</strong> each wind farm). The<br />

assessment concentrates on cumulative wind farms within a 35 km radius of the site and<br />

more specifically the developments which are likely to influence the decision making process.<br />

Nature and Scope of Effects<br />

9.2.17 Landscape effects derive from changes in the physical landscape which may give rise to<br />

changes to its palette of key characteristics and thus its character and how this is<br />

experienced. This may in turn affect the perceived value ascribed to the landscape.<br />

9.2.18 Visual effects relate to the changes that arise in the composition of available views as a result<br />

of changes to the landscape, to people’s responses to the changes and to the overall effects<br />

with respect to visual amenity.<br />

9.2.19 Standard practice treats landscape and visual effects separately and, as a matter of<br />

convention, landscape effects have been dealt with first.<br />

Assessment Process<br />

9.2.20 The assessment of landscape effects <strong>for</strong> the project has followed a recognised process set<br />

out below:<br />

• Identify the baseline landscape resource (e.g. individual landscape elements and<br />

landscape character) and its value;<br />

• Identify <strong>for</strong>ces <strong>for</strong> change in the landscape of the surrounding area;<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

• Evaluate the sensitivity of the landscape resource to the type of development<br />

proposed;<br />

• Identify potential landscape effects of the project through review of initial plans;<br />

• Develop measures to avoid, reduce and ameliorate adverse effects;<br />

• Identify scale or magnitude of change proposed;<br />

• Assess the significance of effects of the project on the landscape, taking into account<br />

the mitigation measures proposed; and<br />

• Report the findings of the assessment.<br />

9.2.21 The assessment of visual effects followed a recognised process set out below:<br />

• Identify potential visual receptors of the project (i.e. people who will have views of the<br />

development);<br />

• Select an appropriate number of representative or sensitive viewpoints to reflect the<br />

full range of different views towards the project;<br />

• Describe the nature of the baseline views towards the project <strong>for</strong> each representative<br />

viewpoint;<br />

• Identify <strong>for</strong>ces <strong>for</strong> change in the visual amenity of the surrounding area;<br />

• Evaluate the sensitivity of the visual receptors represented by the viewpoints;<br />

• Identify potential visual effects of the project through review of initial plans;<br />

• Develop measures to avoid, reduce and ameliorate adverse effects;<br />

• Identify the scale or magnitude of the proposed changes;<br />

• Assess the significance of effects on the view from representative viewpoints, taking<br />

into account the visual context of the development and the mitigation measures<br />

proposed;<br />

• Assess the significance of effects on overall visual amenity; and<br />

• Report the findings of the assessment.<br />

9.2.22 The assessment of representative viewpoints has been supplemented by scheduling of<br />

specific visual receptors within 2 km of the proposals and selected additional site visits to<br />

various locations in the vicinity to determine visual effects upon those likely to be affected to<br />

the greatest degree.<br />

Views, Visual Receptors and Viewpoints<br />

Zone of Theoretical Visibility (ZTV)<br />

9.2.23 Areas from which views of the proposed wind farm would be theoretically possible have been<br />

determined by means of ZTV analysis (as described in Appendix 9.2). These are shown on<br />

Figures 9.3 and 9.4 and show areas within the 35 km study area from which views to the top<br />

of the turbine towers and blade tips would be theoretically visible assuming a “bare-earth”<br />

scenario. A 10 km radius area shows the ZTV in more detail at Figures 9.5 and 9.6.<br />

9.2.24 The ZTV was created using 10 m DSM profile data. This data uses terrain/land<strong>for</strong>m only and<br />

does not take into account the screening effect of buildings, structures and vegetation. It<br />

there<strong>for</strong>e represents a worst-case visibility scenario. For the purposes of this assessment the<br />

extent of the ZTV is assumed to be broadly the same <strong>for</strong> the construction phase and the<br />

operational phase.<br />

Field Surveys<br />

9.2.25 Field surveys have been undertaken over a number of months providing a good<br />

understanding of the site and study area.<br />

9.2.26 The landscape character types <strong>for</strong> the study area, as noted in the relevant SNH Landscape<br />

Character Assessments, were reviewed and the key characteristics of the landscape were<br />

identified. This provided an overview of the character types of the study area and how these<br />

areas might be affected by the proposed wind farm.<br />

9.2.27 The visual amenity of the study area was surveyed to note the general characteristics of both<br />

static and sequential views, from a selection of receptors likely to experience views of the<br />

proposed Wind Farm. The range of views covered a variety of viewing distances, aspects,<br />

elevations and extents and included individual residential properties, settlements, tourist and<br />

recreational destinations and routes.<br />

9.2.28 The study area was traversed extensively during the field study to verify the extent of the ZTV<br />

maps. This has provided a more detailed and accurate understanding of the theoretical<br />

visibility of the proposal. The field survey allowed an appreciation of the scale, extent,<br />

prominence and distance of the receptor from the proposed wind farm, to be experienced.<br />

9.2.29 The field survey is essential to in<strong>for</strong>m the sequential impact assessment. The landscape<br />

characteristics of the route corridors and the views which can be gained throughout a journey<br />

can be understood, and how they are likely to be affected by the proposal. Similarly, the field<br />

survey is essential to the cumulative impact assessment, both in terms of assessing the<br />

combined impact of the various wind farms under consideration, and in terms of considering<br />

the overall capacity of the receiving landscape <strong>for</strong> wind farm development.<br />

Static Effects<br />

9.2.30 The assessment of static visual effects is through analysis of individual viewpoints that are<br />

considered representative of the range of views within the study area.<br />

Sequential Effects<br />

9.2.31 Individual viewpoints are selected on the basis of where the proposal is theoretically visible<br />

from and where it is likely to have a significant effect. This can create a slightly misleading<br />

impression when assessing a number of viewpoints along a route. The sections of the route<br />

from where the proposal is not visible tend not to be represented through viewpoints.<br />

9.2.32 The assessment of sequential effects is there<strong>for</strong>e undertaken partly through the analysis of<br />

viewpoints along main transport routes, partly through an assessment of the existing and<br />

proposed characteristics of the route, and partly through analysis of other visualisation tools<br />

such as the ZTV.<br />

9.2.33 Throughout the study area users of a small number of roads, National Trails, Rights of Way<br />

and core paths would experience changes due to the introduction of the proposed wind farm<br />

in the view. Receptors assessed as part of the sequential assessment are shown in Figure<br />

9.19. Further assessment of other wind farms within the 35 km radius study area has been<br />

considered in the cumulative sequential assessment section of this chapter.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

9.2.34 The sensitivity of occupiers of vehicles on roads as visual receptors varies in this<br />

assessment, according to whether they are:<br />

• Principal local routes on which the relatively high speed and volume of traffic reduces<br />

the road's sensitivity as a viewpoint to medium or low sensitivity;<br />

• Other 'A' and 'B' roads - medium sensitivity;<br />

• Minor roads and lanes with generally low speeds and traffic volumes. May be used as<br />

recreational routes by walkers or riders – high or medium sensitivity;<br />

• Main tourist routes - high sensitivity.<br />

9.2.35 The potential <strong>for</strong> effects to occur in views from roads and Rights of Way is restricted to views<br />

that occur when travelling towards the proposed wind farm. Although there is potential <strong>for</strong><br />

views towards the proposed wind farm from roads in the local area, much will depend on<br />

local circumstances including the extent to which roadside vegetation or <strong>for</strong>estry filter or<br />

screen views towards the site.<br />

9.2.36 The roads assessed in the sequential assessment are the B818 from Balfron to Carron<br />

Bridge, the B822 Campsie Fells, the A811 from Drymen to the junction with the A81 and the<br />

minor road east of Earl’s Hill to Todholes Bridge. Occupiers of vehicles in these locations<br />

would be receptors of medium sensitivity. Walkers using the minor road east of Earl’s Hill<br />

would be of high sensitivity. Walkers using the West Highland Way from Balmaha to Conic<br />

Hill would be of high sensitivity to sequential effects on views.<br />

Cumulative Effects<br />

9.2.37 Cumulative effects are the effects of the proposed wind farm in combination with other<br />

existing and proposed wind farms in the study area.<br />

9.2.38 As with the assessment of landscape effects, cumulative landscape effects can either be<br />

directly on the physical fabric of the landscape, or indirectly on the character of the<br />

landscape.<br />

9.2.39 Cumulative effects on visual amenity can be experienced either from static viewpoints, where<br />

two or more developments can be seen from a single location (combined visibility); or<br />

sequentially, where in the process of moving along a route, two or more proposals are visible.<br />

9.2.40 Combined visibility is experienced either in combination, where more than one wind farm is<br />

visible within the same field of view, or in succession, where only by turning to face another<br />

direction is any other wind farm visible. The proposed turbines in this instance are over 100m<br />

high, <strong>for</strong> which the SNH cumulative assessment guidance of March 2012 recommends a<br />

minimum study area of 60 km radius, with a detailed assessment to focus on schemes within<br />

a 35 km radius. The majority of the baseline data gathering and figure preparation was<br />

undertaken prior to the publication of the March 2012 guidance and was based on a study<br />

area radius of 70 km. This larger study area has been retained <strong>for</strong> the project.<br />

9.2.41 The assessment of cumulative effects uses the same visualisation tools available <strong>for</strong> the<br />

assessment of landscape and visual effects. ZTVs, wireframes, and photomontages have all<br />

been used as part of this assessment. Detailed cumulative methodology <strong>for</strong> the assessment<br />

is discussed later in this chapter from paragraph 9.9.1, given the detailed and discrete nature<br />

of the assessment.<br />

9.2.42 An initial list of all proposals within 70 km of the proposed wind farm was prepared based on<br />

in<strong>for</strong>mation derived from Scottish Natural Heritage (SNH) and the RenewableUK (RUK)<br />

(<strong>for</strong>merly BWEA) and the Stirling Council. This was sent to the various council regions in<br />

which the proposals are based <strong>for</strong> comment.<br />

9.2.43 The assessment of cumulative effects describes in detail the effects of each individual wind<br />

farm proposal within 35 km of the proposed wind farm, and with which it interacts, including<br />

supporting graphics such as cumulative ZTVs. Cumulative wireline visualisations include all<br />

schemes within 35 km. The study of the detailed 35 km radius area (Figure 9.3) includes a<br />

discussion of the overall capacity of the receiving landscape to accommodate wind farm<br />

development.<br />

9.2.44 In assessing the cumulative effects of wind farms within 35 and 70 km (Figure 9.15 and 9.16),<br />

the assessment has focused on proposals relating to geographic distribution and their<br />

interaction with the proposed wind farm, particularly from popular hill top destinations in the<br />

study area. Combined and successive views and sequential views from transport routes have<br />

also been assessed.<br />

Relevant Considerations<br />

9.2.45 There are a number of relevant considerations relating to the appearance of the proposed<br />

wind farm and its relationship with the landscape, which also in<strong>for</strong>m the assessment. These<br />

include:<br />

• Backdrop: turbines seen against a single backdrop, e.g. sky or moorland, will<br />

generally be more coherent than those viewed against a variety of backdrops. Where<br />

one particular backdrop predominates, the selection of an appropriate colour and<br />

texture <strong>for</strong> the turbines can help mitigate the effects by reducing their visibility against<br />

this backdrop;<br />

• Scale: the scale of the receiving landscape has an effect on its ability to accommodate<br />

particular proposals. In general, the large scale of the turbines tends to be better<br />

accommodated in a large scale and relatively simple landscape. In addition,<br />

uncom<strong>for</strong>table comparisons of scale can be created where the turbines are seen in the<br />

context of elements of a more domestic scale such as housing;<br />

• Focus: specific viewpoints may focus in a particular direction. The location of the<br />

proposed development site in relation to this focus can affect the significance of the<br />

effect, particularly as individual turbines and wind farms can <strong>for</strong>m vertical focal points<br />

within the landscape;<br />

• Unity: the relationship of the turbines to each other affects whether the wind farm<br />

reads as a cohesive entity or as fragmented. Turbines overlapping can also produce a<br />

distracting and uncom<strong>for</strong>table visual effect. It is virtually inevitable that from some<br />

angles this will occur, but the extent to which this happens, and the importance of the<br />

views from where this takes place has an influence on the significance of the effect.<br />

Other vertical elements, such as pylons, can also detract from the unity of the proposal<br />

and add to a sense of visual confusion;<br />

• Movement: the movement of an object in a landscape that provides distraction or<br />

interest including the rotation of a turbine. This can relate to landscapes which are<br />

relatively still and static and landscapes which are constantly changing and transient;<br />

and<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

• Setting: the combination of land<strong>for</strong>m, <strong>for</strong>eground, background and features within a<br />

view, which provide the landscape setting, influences the nature of the effect of a wind<br />

farm. Setting also relates to the complexity or simplicity of the landscape or view and<br />

the sense of remoteness or development, which provide the context <strong>for</strong> the proposal.<br />

Visualisations<br />

9.2.46 Photomontages of the proposed wind farm were prepared <strong>for</strong> selected viewpoints with<br />

reference to methodology recommended in Visual Representation of Wind Farms; Best<br />

Practice Guidance, Scottish Natural Heritage (2007), and as set out at Appendix 9.3. The<br />

viewpoint locations are shown on Figures 9.3 to 9.6 and the visualisations (all showing<br />

photomontages and wirelines) on Figures 9.14, sets 1a to 20c.<br />

9.2.47 The majority of the photographs were taken in favourable conditions and clear visibility.<br />

Where this was not possible the computer generated wind turbines have been adjusted to<br />

achieve enough contrast to aid visibility.<br />

9.2.48 The blade movement and yaw angle of the wind turbines both vary depending on wind speed<br />

and direction. This assessment assumes that the wind turbine blades would be in motion and<br />

facing the viewer. It should be noted that there would be occasions when the rotors would be<br />

stationary and viewed from the side or obliquely, both of which would reduce the magnitude<br />

of change to visual receptors.<br />

Assessment of Landscape Effects<br />

9.2.49 The starting point <strong>for</strong> any assessment is a desk based study of published landscape<br />

assessments. A description and evaluation of the landscape of the area over which change is<br />

likely to be experienced has been based on these assessments. The assessment of effects is<br />

based on this baseline in<strong>for</strong>mation and also takes into account landscape sensitivity.<br />

Value<br />

9.2.50 The assessment, in addition to covering landscape character, seeks to identify landscapes or<br />

parts of the landscape resource whose attributes are or may be valued. This may be<br />

determined in the first instance through the presence of designations. In the absence of<br />

established consensus as to a landscape’s value or the value of different parts of the<br />

landscape resource, it may be necessary <strong>for</strong> the assessor to define and apply her/his<br />

definition of value.<br />

9.2.51 With respect to value, the following definitions have been used in this assessment:<br />

Table 9.1 Landscape Value (expressed through designation)<br />

Value Designation Example<br />

High National Very attractive or attractive scenic quality, high or good landscape quality,<br />

no or limited potential <strong>for</strong> substitution.<br />

E.g. National Park, NSA or key elements within them.<br />

Medium Regional/Local<br />

Positive character, typical or in part unusual scenic quality, ordinary<br />

landscape quality, potential <strong>for</strong> substitution.<br />

E.g. Regionally or locally designated (RSA/AGLV) or undesignated but<br />

value expressed through literature and cultural associations or through<br />

demonstrable use.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

Value Designation Example<br />

Low Local Dull, degraded or damaged scenic quality, poor landscape quality, can be<br />

readily substituted.<br />

E.g. Undesignated. Certain individual landscape elements or features may<br />

be worthy of conservation, and landscape either identified or would benefit<br />

from restoration or enhancement.<br />

9.2.52 It should be noted that, in virtually all circumstances, landscapes are valued, sometimes<br />

highly valued, in the local context by various, if not all, sectors of the community.<br />

Condition<br />

9.2.53 The evaluation of condition is based on judgements about the physical state of the landscape<br />

resource. It reflects the state of repair of individual features and elements, as indicated by<br />

the categories within the scale below, or can be applied to the intactness of the resource as a<br />

whole outlined by the corresponding descriptions:<br />

Table 9.2 Landscape Condition<br />

Condition<br />

Example<br />

Very Good Strong structure; very attractive with distinct features worthy of conservation; strong sense<br />

of place; no detracting features.<br />

Good<br />

Ordinary<br />

Poor<br />

Very Poor<br />

Recognisable structure; attractive with many features worthy of conservation; occasional<br />

detracting features.<br />

Distinguishable structure; common place with limited distinctiveness and features worthy<br />

of conservation; some detracting features.<br />

Weak structure; evidence of degradation; lacks distinctiveness and sense of place;<br />

frequent detracting features.<br />

Damaged structure; evidence of severe disturbance or dereliction; no distinctiveness;<br />

detracting features dominate.<br />

9.2.54 With respect to the assessment of effects, it is necessary to establish in the first instance,<br />

whether, and to what extent, the proposed change would exert a locally characterising effect.<br />

Would the introduced element become the principal element/feature which determines<br />

landscape character? In these circumstances, the element would be dominant with the<br />

surrounding landscape elements being sub-dominant or incidental in comparison. Moving<br />

outwards and away from the proposed introduction, the element would exert a lessening<br />

effect on landscape character with the surrounding context increasing in influence and<br />

becoming co-dominant in a mixed landscape sub-type. Farther afield the introduced element<br />

would become a noticed, then increasingly incidental element, with the original balance of<br />

elements reasserting their original dominance.<br />

9.2.55 Appendix 9.4 sets out a series of examples illustrating the potential landscape effects arising<br />

from wind farm development and, at the same time, illustrates part of the relationship<br />

between landscape effects and visual effects.<br />

9.2.56 Significance in landscape character terms is defined to the extent to which new landscape<br />

types/character area and/or sub-types/areas would be established. This will be determined by<br />

considering the key characteristics of the receiving landscape in combination with the<br />

Carron Valley Wind Farm<br />

magnitude of change arising and the extent to which the key characteristics are felt to be<br />

affected locally and over the broader landscape character area/type.<br />

9.2.57 With respect to sensitivity, the GLVIA states that:<br />

‘The sensitivity of the landscape to change is reflected in the degree to which a<br />

landscape is able to accommodate change (due to a particular development or land use<br />

change) without adverse effects on its character. This may be influenced by the extent<br />

of existing or new land<strong>for</strong>m and/or existing vegetation or new planting. These and other<br />

factors determine the visibility of the proposed development and there<strong>for</strong>e influence the<br />

extent of its effect on the perceived character and visual amenity of the surrounding<br />

landscape’ (para2.27). Landscapes vary in their capacity to accommodate different<br />

<strong>for</strong>ms of development. Sensitivity is thus not absolute but is likely to vary according to<br />

the existing landscape, the nature of the proposed development and the type of change<br />

being considered. Sensitivity is not there<strong>for</strong>e part of the landscape baseline, but is<br />

considered during the assessment of effects’ (para 2.28).<br />

9.2.58 With regard to sensitivity the following is also derived from GLVIA, p.87, paragraph 7.16 and<br />

7.17;<br />

‘The degree to which a landscape type or area can accommodate change arising from a<br />

particular development without detrimental effects upon its character will vary with<br />

existing land use, the pattern and scale of the landscape, visual enclosure/ openness of<br />

views, and distribution of visual receptors, the scope <strong>for</strong> mitigation (which would be in<br />

keeping with the existing landscape) and the value placed on the landscape…. The<br />

determination of the sensitivity of the landscape resource is based upon an evaluation<br />

of each key element or characteristic of the landscape likely to be affected. The<br />

evaluation will reflect such factors as its quality, value, contribution to landscape<br />

character, and the degree to which the particular element or characteristic can be<br />

replaced or substituted’.<br />

9.2.59 As described above, landscape sensitivity is influenced by a number of factors including<br />

value, condition and the type of change brought about by the project. In order to assist with<br />

bringing these factors together the following four point scale has been used. However, this<br />

table can only illustrate general categories and there is scope <strong>for</strong> the landscape resources to<br />

be categorised differently depending on the specific proposals. The assessment of absolute<br />

sensitivity will be determined as part of the overall assessment process.<br />

Example<br />

Total loss of/ very substantial alteration to key elements/ features/characteristics of the<br />

uncharacteristic with the attributes of the receiving landscape which would give rise to a<br />

different characterising effect.<br />

Partial loss of/moderate alteration to one or more key elements/features/characteristics of<br />

the baseline i.e. pre-development landscape and/or introduction of elements that may be<br />

prominent, but may not necessarily be substantially uncharacteristic with the attributes of<br />

the receiving landscape, but which could co-characterise parts of the landscape, or<br />

introduction of elements within the surrounding landscape which may give rise to a<br />

different characterising effect.<br />

Minor loss of/alteration to one or more key elements/features/characteristics of the<br />

baseline i.e. pre-development landscape and/or introduction of elements that may not be<br />

uncharacteristic with the surrounding landscape or may not lead to a characterising or cocharacterising<br />

effect.<br />

Very minor loss of/alteration to one or more key elements/features/characteristics of the<br />

baseline i.e. pre-development landscape and/or introduction of elements that are not<br />

uncharacteristic with the surrounding landscape or which do not have any materially<br />

characterising effect - approximating the ‘no-change’ situation.<br />

Assessment of Visual Effects<br />

9.2.61 The assessment of visual effects is based on the magnitude of the change and the relative<br />

sensitivity of the receptors (viewers).<br />

9.2.62 To assess the significance of effects, magnitude is considered together with sensitivity. The<br />

GLVIA states at paragraph 7.31, that the sensitivity of the receptor will depend on a number<br />

of factors:<br />

• The location and context of the viewpoint;<br />

• The expectations or activity of the receptor;<br />

9.2.63 Those living within view of the proposed wind farm are most likely to be included in the<br />

highest sensitivity group along with those engaged in outdoor pursuits and <strong>for</strong> whom<br />

landscape experience is the primary objective. For assessment purposes, the sensitivity<br />

levels listed in Table 9.5 are considered appropriate with assessment being concentrated on<br />

the two groups of potentially highest sensitivity (residents and those engaged in outdoor<br />

landscape experience recreation).<br />

9.2.64 The magnitude of the change to an existing view is determined by a number of interrelated<br />

factors such as the distance from the project to the receptor; the proportion of the<br />

development visible as well as the absolute visibility of the scheme, the height of the<br />

development relative to the receptor with reference also to the scale of other features in the<br />

view and the number and character of elements which would be lost from or added to the<br />

view.<br />

9.2.65 The magnitude of likely effects is categorised as follows:<br />

Example<br />

Complete or very substantial change in view: Proposed development will be<br />

complete change in character and composition of baseline, i.e. predevelopment<br />

view through removal of key elements or addition of<br />

uncharacteristic elements, which may or may not be visually discordant.<br />

Moderate change in view: which may involve partial obstruction of existing view<br />

or partial change in character and composition of baseline i.e. pre development<br />

view through the introduction of new elements or removal of existing elements.<br />

Proposed development will be prominent, but not substantially different in scale<br />

and character from the surroundings and the wider setting. Composition of the<br />

view will alter. View character may be partially changed through the introduction<br />

of features which, though new, may not necessarily be visually discordant.<br />

Significance of Effects<br />

9.2.66 With regard to ‘significance’ the GLVIA states the following:<br />

“Significance is not absolute and can only be defined in relation to each development<br />

and its location. It is <strong>for</strong> each assessment to determine the assessment criteria and the<br />

significance thresholds, using in<strong>for</strong>med and well-reasoned judgement supported by<br />

thorough justification <strong>for</strong> their selection and explanation as to how the conclusions about<br />

significance <strong>for</strong> each effect assessed have been derived.” (GLVIA 2nd Ed, para 7.38,<br />

p92).<br />

9.2.67 Significance of landscape and visual effects is derived from magnitude of change and<br />

sensitivity. The GLVIA notes that;<br />

“The two principal criteria determining significance are the scale or magnitude of effect<br />

and the environmental sensitivity of the location or receptor. A higher level of<br />

significance is generally attached to large-scale effects and effects on sensitive or highvalue<br />

receptors; thus small effects on highly sensitive sites can be more important than<br />

large effects on less sensitive sites. It is there<strong>for</strong>e important that a balanced and wellreasoned<br />

judgement of these two criteria is achieved” (para 7.39).<br />

“Thus significance cannot be defined in any context independent of the proposal under<br />

consideration and in its geographical context. That is, significance is unique <strong>for</strong> each<br />

proposal…” Box 7.3 of the GLVIA.<br />

“In the context of EIA ‘significance’ varies with the type of project and the topic under<br />

assessment, in the assessment of landscape and visual effects “…the assessor must<br />

clearly define the criteria used in the assessment <strong>for</strong> each project using his or her skill<br />

based on professional judgement” (para 7.42).<br />

9.2.68 EIA is a means of drawing together, in a systematic way, an assessment of a project’s likely<br />

significant environmental effects. It is accepted from the outset that wind farm development<br />

could potentially give rise to significant effects. However, not all landscape and visual effects<br />

arising would be significant in EIA terms. The table below sets out in matrix <strong>for</strong>m the main<br />

correlations between magnitude and sensitivity <strong>for</strong> both landscape and visual effects and<br />

<strong>for</strong>ms a variation of the generic matrix at Table 2.2 of Chapter 2: The Environmental Impact<br />

9.2.69 In the assessment of visual effects, those effects indicated as being of ‘Substantial’ or ‘Major’,<br />

significance (as derived through the application of the methodology set out above) may be<br />

regarded as significant effects in EIA terms. An accumulation of individual ‘Moderate’ effects<br />

may also be regarded as significant in terms of the EIA regulations. Where the sensitivity or<br />

magnitude is of the highest level i.e. High or Large respectively, the matrix offers the choice<br />

of two potential significances of effect. The assessor is then required to use professional<br />

judgement to define the level of significance in these most important scenarios.<br />

9.2.70 With respect to the assessment of landscape effects, areas over which the proposed wind<br />

farm is likely to give rise to new landscape types / character areas and/or where sub-types/<br />

areas would be established are most likely to be deemed significant in EIA terms. However,<br />

significance can vary depending on individual circumstances and the baseline situation, <strong>for</strong><br />

example the presence of landscape designations and/or detractors. This is particularly the<br />

case in assessing whether (or not) a proposed development would (a) give rise to a new<br />

landscape character type in its own right where the proposed development would be the<br />

defining landscape characteristic and/or (b) give rise to a new landscape sub-type in which<br />

the proposed development would be a major contributory element in defining character. In<br />

the first case the resulting effect would normally be significant. In the second case the<br />

assessor has used professional judgement to determine if the effect is significant or not.<br />

Types of Effect<br />

9.2.71 The landscape and visual resource of an area can be affected both directly and indirectly.<br />

Visual effects are always direct because when an object is not in view by implication there<br />

can be no effect. Landscape effects on the other hand can be either direct or indirect.<br />

Change that affects onsite physical features (e.g. vegetation, buildings and land<strong>for</strong>m), or the<br />

character area/type in which the site is located, is a direct landscape effect, whereas an effect<br />

on the character of the surrounding landscape character areas/type is indirect. It is generally<br />

assumed that indirect effects would be intrinsically less significant than direct ones. However,<br />

this is not necessarily the case and is dependant on the nature of the proposal and the<br />

landscape in which it is situated. The effect on the cultural setting of a particular designated<br />

site or object is considered further within Chapter 10: Cultural Heritage and Archaeology.<br />

9.2.72 In general the scope of landscape and visual effect is:<br />

a) Direct effects on the landscape fabric and character of the site, and on views and<br />

visual amenity; and<br />

b) Indirect effects on the surrounding landscape character.<br />

View Ranges<br />

9.2.73 Experience from recent wind farm projects and planning appeals in the UK indicates that<br />

100 m high plus wind turbines are perceived as ‘prominent’ features in the landscape at 0-<br />

3 km and are ‘present’ from 3-10 km, with the degree of ‘presence’ diminishing with distance.<br />

Beyond 10 km the presence of the wind turbines would gradually reduce as they are<br />

perceived more and more as part of the landscape at large. For the purposes of this<br />

assessment, views have been classified according to three distance ‘ranges’ as follows:<br />

Table 9.9 View Ranges<br />

Range<br />

Distance<br />

threshold<br />

Reasoning<br />

Close<br />

Less than 3 km At close range the proposals would appear as ‘prominent’ features and<br />

visual receptors would tend to experience large to small / medium<br />

magnitude of change when compared with existing views.<br />

Medium<br />

Between 3 km<br />

and 10 km<br />

In medium range views the proposals would appear as ‘present’ features<br />

and visual receptors would tend to experience small / medium to<br />

negligible/ small magnitude of change compared to the existing situation.<br />

Long More than 10<br />

km<br />

In long range views the proposals would read as part of the landscape and<br />

visual receptors would tend to experience a small to negligible or lower<br />

magnitude of change compared to the existing situation.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

Terminology and Definitions<br />

9.2.74 ‘Visual amenity’ is understood to be the visual benefit or pleasantness provided by the<br />

environment as enjoyed in views with the emphasis on residential properties and public<br />

recreation resources. The visual resource of a particular area is made up of both views and<br />

general visual amenity. These two elements are assessed together from specific viewpoints.<br />

9.2.75 For the purposes of this assessment consideration has been given as to whether a ‘wind farm<br />

landscape type’ is likely to be created up to 1 km from the proposed wind farm, depending on<br />

the extent of the ZTV and intervening land <strong>for</strong>m, land cover and landscape character. Where<br />

the landscape baseline is developed to varying degrees or, the presence of visual detractors<br />

is significant, this distance threshold may be less. The same determining factors apply to the<br />

creation of a ‘wind farm landscape sub-type’ which may occur up to 2 km from the proposed<br />

wind farm. The mechanics of how and when these wind farm types and sub-types are <strong>for</strong>med<br />

is explained at Appendix 9.4 with the aid of diagrams.<br />

Climate and Weather Conditions<br />

9.2.76 In addition to the physical features of the landscape, climate and weather conditions affect<br />

perception and experience of the landscape. Changes in perception affect people’s<br />

responses to the landscape and may influence the perceived effect of the proposal.<br />

9.2.77 The main climatic influences are exposure, sunshine, precipitation and day length. Generally,<br />

Scotland is fairly cloudy due to the frequency of low-pressure systems from the Atlantic<br />

Ocean. In addition, day length varies with the seasons. Precipitation (rainfall and snowfall) in<br />

Scotland is very variable and is determined by topography and geographic location. The area<br />

with the highest precipitation is the Western Highlands, and the driest area is the east coast.<br />

The proposed wind farm site and study area has significantly more cloudy days and annual<br />

rainfall than areas at lower elevation to the east of the country.<br />

9.2.78 Views from a number of peaks within the study area are influenced by the weather<br />

conditions. These influence the number of clear days when views can be experienced.<br />

9.2.79 Scotland can also have periods of excellent visibility, as the greater part of the country is<br />

remote from the more industrial and populous areas of Great Britain and mainland Europe<br />

free from air pollutants. These conditions however, are generally experienced <strong>for</strong> a limited<br />

time, due to the prevailing climatic influences across the north. The assessment of effects is<br />

based on a worst case scenario of excellent visibility experienced during clear atmospheric<br />

conditions and bright or sunny weather.<br />

Carron Valley Wind Farm<br />

Overview of the Proposal Site<br />

9.3.2 The proposal site lies within the Carron Valley on the northern shores of the Carron Valley<br />

Reservoir. The site extends over the rounded land<strong>for</strong>m of Cairnoch Hill which rises from<br />

226 m AOD at the reservoir to 413 m AOD at the peak. To the north lie the Fintry,<br />

Gargunnock and Touch Hills which combine as an undulating plateau of uplands and to the<br />

south lies the ridge of Kilsyth Hills and Campsie Fells. These upland areas provide the<br />

immediate context of the proposal site due to the location of the site within this combined<br />

upland plateau area well away from visually distinctive hill edges, which contrast with the<br />

relatively flat expanses of the Forth Valley and the Kelvin/Clyde Valley.<br />

Land Use<br />

9.3.3 The current land use of the proposals site is commercial <strong>for</strong>estry, owned and managed by the<br />

FCS. The land is divided into a broad mosaic of large scale geometric woodland blocks of<br />

different aged trees, interspersed with open areas which have been clear felled. A network of<br />

tracks provide vehicular access within the site. These features together with linear breaks<br />

between plantations and post and wire mesh fencing further define the site within this<br />

managed landscape. A few stone wall field boundaries <strong>for</strong>m remnants from the site’s<br />

previous agricultural land use. The grassed over earth work remains of Sir John de Graham’s<br />

Castle lie in a clearing in the south west corner of the site. This is a Scheduled Monument<br />

and is described and assessed within Chapter 10: Cultural Heritage and Archaeology.<br />

Vegetation<br />

9.3.4 The majority of vegetation on site comprises coniferous tree species planted <strong>for</strong> commercial<br />

timber production. Species include predominantly Sitka spruce (Picea sitchensis) with small<br />

blocks of European larch (Larix decidua). In areas where trees have been felled a mix of<br />

rough grassland, ruderal weeds and gorse scrub has become established. Adjacent to the<br />

B818, on the fringes of the site, lies an intermittent strip of grass with clumps of native<br />

deciduous trees and shrubs providing a contrast with the confer plantations. Species include<br />

Goat willow (Salix caprea), Alder (Alnus glutinosa) and Silver birch (Betula pendula).<br />

Communications<br />

9.3.5 There are no roads within the site. The B818 follows the alignment of the southern boundary,<br />

between the <strong>for</strong>estry and the reservoir.<br />

Settlement<br />

9.3.6 There are no towns or villages adjacent to the proposal site or within the local study area.<br />

Residential properties are scattered along the B818.<br />

Core Paths and Access<br />

9.3.7 There is one public right of way, designated as a ‘core path’ which links the north western<br />

corner of the site on the access track to Cringate and continues north up the valleys of<br />

Endrick Water and Backside Burn towards Kippen. Several core paths are also associated<br />

with the Carron Valley Forest on the south side of the reservoir.<br />

Designated Landscapes<br />

9.3.8 A distinction has been made between designations <strong>for</strong> amenity and landscape, active<br />

conservation management designations and cultural heritage designations. Designations <strong>for</strong><br />

species and special habitats are dealt with in Chapter 6: Terrestrial Ecology. Where any of<br />

these designations also function as visitor destinations, these have been assessed<br />

additionally as landscape and visual receptors. Landscape designations are illustrated within<br />

Figures 9.10 to 9.12. Other designation types are assessed in Chapters 6: Terrestrial<br />

Ecology and 10: Cultural Heritage and Archaeology.<br />

International Designations<br />

9.3.9 The European Landscape Convention (ELC), also known as the Florence Convention, is the<br />

first international convention to focus specifically on landscape with respect to designations.<br />

The convention promotes the protection, management and planning of European landscapes.<br />

The ELC was ratified by the UK Government in November 2006 and came into <strong>for</strong>ce in March<br />

2007.<br />

9.3.10 Although the convention does not contain policies on landscape protection or management,<br />

nor designate specific areas based upon their landscape and visual amenity, it does provide<br />

aims to ensure that policies are put into place by those involved in managing the landscape.<br />

National Designations<br />

Loch Lomond and the Trossachs National Park<br />

9.3.11 The Loch Lomond and the Trossachs National Park lies approximately 20 km to the north<br />

west of the proposal site. The National Park (Scotland) Act 2000 defines the following four<br />

key objectives <strong>for</strong> National Parks;<br />

• ‘To conserve and enhance the natural and cultural heritage of the area,<br />

• To promote sustainable use of the natural resources of the area,<br />

• To promote understanding and enjoyment (including enjoyment in the <strong>for</strong>m of<br />

recreation) of the special qualities of the area by the public, and<br />

• To promote sustainable economic and social development of the area's communities’.<br />

9.3.12 The Loch Lomond and the Trossachs National Park Local Plan adopted in October 2011<br />

states within Policy SQ1 Conserving and Enhancing Special Qualities underpins all policies,<br />

programmes and activities within the plan.<br />

9.3.13 The Special Qualities of The Loch Lomond and Trossachs National Park are outlined in<br />

Scottish Natural Heritage and Loch Lomond and The Trossachs National Park Authority<br />

(2020) Commissioned Report, No.376, and are determined as follows:<br />

• ‘A world-renowned landscape farmed <strong>for</strong> its beauty;<br />

• Wild and rugged highlands contrasting with pastoral lowlands;<br />

• Water in its many <strong>for</strong>ms;<br />

• The rich variety of woodlands;<br />

• Settlements nestled within a vast natural backdrop;<br />

• Famous through-routes;<br />

• Tranquillity; and<br />

• The easily accessible landscape splendour.’<br />

National Scenic Areas<br />

9.3.14 There are 40 National Scenic Areas (NSAs) in Scotland, two of which lie within the study<br />

area. NSA's were identified in 1978 by the Countryside Commission <strong>for</strong> Scotland and were<br />

established by Order of the Secretary of State in 1981, and can be summarised as follows:<br />

‘…areas of land and water which represent the very best of Scotland’s renowned<br />

scenery. They are of such outstanding natural beauty and amenity that they should be<br />

safeguarded and enhanced as part of the national heritage.’<br />

9.3.15 Furthermore, the Planning etc. (Scotland) Act 2006 gives a statutory basis to NSAs through<br />

an addition to the Town and Country Planning (Scotland) Act 1997, which was brought into<br />

<strong>for</strong>ce through The Town and Country Planning (National Scenic Areas) (Scotland)<br />

Designation Directions 2010. This recent legislation defines a NSA as an area ‘of outstanding<br />

scenic value in a national content’.<br />

9.3.16 The two NSA’s coincide with the Loch Lomond and the Trossachs National Park and are<br />

defined as;<br />

• Loch Lomond NSA;<br />

• The Trossachs NSA.<br />

9.3.17 The Loch Lomond NSA lies within the south eastern part of the National Park and is<br />

described by the National Park Authority as follows;<br />

‘Ben Lomond stands guard over Loch Lomond, the largest expanse of freshwater in<br />

Great Britain and the romantic centrepiece of the National Park. In the north the loch is<br />

deep and narrow, bound by steep-sided mountains. Further south it spills into an island<br />

studded panorama’.<br />

9.3.18 The Trossachs NSA lies within the north eastern part of the National Park and is described by<br />

the National Park Authority as follows;<br />

‘The Trossachs, the wild glens and sparkling lochs between Callander and Aberfoyle –<br />

are often regarded as the ‘Highlands in miniature’. Here the contrast between Highlands<br />

and Lowlands is stark as you leave Aberfoyle to climb up through the twisting Duke’s<br />

Pass to Loch Katrine’.<br />

Regional Designations<br />

Areas of Great Landscape Value<br />

9.3.19 Within Scotland, Areas of Great Landscape Value (AGLVs) were historically designated to<br />

protect small, local areas of scenic and recreational value. These designated landscapes lie<br />

outside of, and complement, the NSAs.<br />

9.3.20 The AGLV in which the site is located lies on the southern edge of the Stirling region,<br />

extending from Killearn in the west to Stirling in the east and comprising the northern slopes<br />

of the Campsie Fells, the Fintry Hills, Touch Hills and Gargunnock Hills.<br />

9.3.21 Some viewpoints have been chosen which coincide with AGLV’s within the study area and<br />

help to illustrate landscape character and views. Views are illustrated in photomontages at<br />

Figures 9.14 1a to 20c.<br />

Regional Scenic Areas<br />

9.3.22 In the SNH commissioned report Environmental Resources Management (2002) (Review of<br />

the role of the National Scenic Area and other landscape designations in the Scottish<br />

planning system, SNH Review No 134), it states that:<br />

‘there is considered to be a need <strong>for</strong> a second tier of high-quality landscape<br />

designations, but the present arrangements <strong>for</strong> this regional level, using many different<br />

names and criteria, are inadequate and confusing’.<br />

9.3.23 The report finds that with respect to regional landscape designations, AGLVs and other<br />

landscape designation names, cause a state of confusion. It suggests that a more consistent<br />

approach across Scotland would help to clarify the level of designation and that a simpler title<br />

of ‘Regional Scenic Areas’ be adopted <strong>for</strong> all regional landscape designations.<br />

9.3.24 There are three Regional Scenic Areas (RSAs) currently identified within the study area, the<br />

Kilpatrick Hills (within West Dunbartonshire), the Campsie Fells (within East Dunbartonshire)<br />

and the Kilsyth Hills (within North Lanarkshire). The latter two RSAs lie adjacent to each other<br />

and abut an AGLV to the north.<br />

Local Designations<br />

9.3.25 Local landscape designations are a well-established and valued approach to protecting areas<br />

of landscape importance. In contrast to nationally designated landscapes, regional<br />

designations are often identified within development plans and their boundaries are defined<br />

and kept under review within local plans. In that respect, regional designations can also be<br />

taken as local landscape designations.<br />

Historic Gardens and Designed Landscapes<br />

9.3.26 The Inventory of Historic Gardens and Designed Landscapes is a growing and evolving<br />

record of nationally important gardens and designed landscapes across Scotland maintained<br />

by SNH and Historic Scotland. These gardens and landscapes are valuable assets at<br />

national, regional and local levels. Sites listed in the inventory are not statutory designations,<br />

but are protected through policies in structure plans and would have at least medium<br />

sensitivity to change.<br />

9.3.27 A garden included in the Inventory does not have legal protection, but it is nonetheless a<br />

material consideration in the planning process (as addressed in SPP, see Chapter 5:<br />

Planning Policy Overview), and it is to be expected that the in<strong>for</strong>mation included in the<br />

Inventory will in<strong>for</strong>m the planning decision maker. In<strong>for</strong>mation regarding these listings is<br />

contained in web based links at Appendix 9.5.<br />

9.3.28 The 42 Historic Gardens and Designed Landscapes identified within the area of search are<br />

shown on Figure 9.10. The following 7 sites coincide with the ZTV:<br />

• Rossdhu, Loch Lomond;<br />

• Buchanan Castle;<br />

• Dunmore Park;<br />

• Talliallan Castle;<br />

• Dunimarle Castle;<br />

• Valley Field, Culross;<br />

9.3.29 The presence of extensive mature woodland and tree planting which <strong>for</strong>ms part of the<br />

wind farm proposal. No significant effects are predicted on the character of the landscape,<br />

their settings or views from them. The potential <strong>for</strong> significant effects on the character of the<br />

landscapes, their settings or views from them is unlikely.<br />

Planning Policy Review<br />

National Planning Policy<br />

National Planning Framework<br />

9.3.30 The Planning etc. (Scotland) Act 2006 requires the National Planning Framework to be taken<br />

into account in the preparation of strategic and local development plans. The National<br />

Planning Framework (NPF) is the Scottish strategy <strong>for</strong> long-term development in Scotland’s<br />

towns, cities and countryside. NPF2, published in June 2009 replaces the first NPF published<br />

in 2004, and outlines the spatial strategy <strong>for</strong> Scotland’s development to 2030.<br />

Scottish Planning Policy<br />

9.3.31 Previous Scottish Planning Policy (SPP) and National Planning Policy Guidance (NPPG)<br />

series have been replaced by a single, consolidated SPP (2010), and in doing so national<br />

planning policy <strong>for</strong> Scotland has been rationalised. Paragraphs 125 – 148 of the SPP (2010)<br />

outline the approach to Landscape and Natural Heritage.<br />

The Loch Lomond and The Trossachs National Park<br />

9.3.32 Within the Loch Lomond and The Trossachs National Park Local Plan, Policy REN5<br />

Renewable Energy Development Adjacent to the National Park Boundary provides some<br />

guidance <strong>for</strong> development outside, although visible from, the National Park, although the<br />

proposed wind farm lies approximately 20 km to the south east of the National Park.<br />

‘The National Park Authority, as a statutory consultee, will support renewable energy<br />

developments outwith the Park where:<br />

(a) They will not individually, or cumulatively with other developments or proposals,<br />

have a significant adverse visual impact on the landscape setting of the Park and<br />

its principal gateways;<br />

(b) They do not result in significant adverse impacts upon protected sites, species or<br />

biodiversity interests within the Park; as a result of cross boundary effects; and<br />

(c) They do not result in significant adverse impacts upon residential amenity by virtue<br />

of proximity, noise generation, shadow flicker, lighting, or visual impact.<br />

The National Park Authority will object to renewable energy developments outwith the<br />

Park where these criteria are not met.’<br />

Local Planning Policy<br />

East Dunbartonshire Council<br />

9.3.33 A number of policies are identified within the East Dunbartonshire Local Plan (October 2011)<br />

of which the following have most relevance to landscape and visual amenity.<br />

Carron Valley Wind Farm<br />

9.3.34 Policy DQ8 – Renewable Energy Developments states:<br />

‘The Council will generally support proposals <strong>for</strong> all types of renewable energy<br />

development except:<br />

a) where there would be an adverse impact on historic and natural environment<br />

resources defined in this plan<br />

b) where there would be an adverse impact on the landscape quality of the Green<br />

Belt, Campsie Fells and Kilpatrick Hills Regional Scenic Areas<br />

c) where there would be an adverse impact on local amenity through traffic, noise and<br />

visual impact<br />

d) windfarm developments in the Campsie Fells and Kilpatrick Hills Scenic Areas’.<br />

9.3.35 Policy NE4 – Protection of Landscape Character states:<br />

‘Development in any location will not be permitted if it would result in significant adverse<br />

impacts on the landscape character of the Green Belt or a Regional Scenic Area<br />

(Kilpatrick Hills/Campsie Fells). In assessing any impact, account will be taken of the<br />

landscape value of any area designated during the life of the plan as of Local<br />

Landscape Quality, and of the findings and recommendations of the Glasgow and Clyde<br />

Valley Landscape Character Assessment. Development within either Regional Scenic<br />

Area should be designed and landscaped so as to protect and rein<strong>for</strong>ce its landscape<br />

character’.<br />

North Lanarkshire Council<br />

9.3.36 With regards to the Kilsyth Hills RSA, the protection af<strong>for</strong>ded to RSAs is identified within the<br />

North Lanarkshire Local Plan Finalised Draft (2009), policy ‘NBE1 Protecting the Natural and<br />

Built Environment, A Natural Environment’, which states:<br />

‘The Council will safeguard sites of importance <strong>for</strong> natural heritage and Biodiversity from<br />

development. Planning permission will only be granted <strong>for</strong> proposals potentially<br />

affecting these sites of recognised importance if the applicant demonstrates to the<br />

Council’s satisfaction that there will be no adverse impact, or that any impacts can be<br />

mitigated in environmental terms relevant to the impact’.<br />

Stirling Council<br />

9.3.37 The Development Plan <strong>for</strong> Stirling comprises the Stirling Council Local Plan (adopted 1999)<br />

and the Clackmannanshire and Stirling Structure Plan (2002). Identified within the<br />

Clackmannanshire and Stirling Structure Plan (March,2002) Policy ENV2 states, with regards<br />

to Protected Landscapes:<br />

‘1. In National Scenic Areas development will only be permitted where there is a<br />

specific site requirement <strong>for</strong> the development which council not be met in a less<br />

sensitive location, and where the nationally important landscape character and<br />

scenic interest of the designated area would not be adversely affected.<br />

Developments which are approved will be expected to satisfy particularly rigorous<br />

quality stands.<br />

2. In Areas of Great Landscape Value development will only be permitted if it satisfies<br />

the requirements of Policy ENV3 and can be accommodated without adversely<br />

affecting the overall quality of the designated landscape area.’<br />

Carron Valley Wind Farm<br />

9.3.38 The proposed wind farm site is located within an AGLV, and as such, Policy ENV3 of the<br />

Clackmannanshire and Stirling Structure Plan applies:<br />

‘In areas of Countryside, as defined in Local Plans, development will only be permitted<br />

where:<br />

1. The proposed enterprise of activity is dependent upon a countryside location; or<br />

2. It accords with Policy ED4.<br />

3. All development in the Countryside should, both in function, siting and design, be<br />

suitable <strong>for</strong> its particular location, and should respect and preserve features<br />

contributing to local character. Proposals satisfying these criteria should where<br />

possible re-use redundant vernacular buildings.’<br />

9.3.39 The Stirling Council Local Plan (1999) also identifies a number of policies relevant to<br />

landscape and visual amenity. Policy E10 states:<br />

‘Subject to all other relevant policies in the Plan, and providing that the development will<br />

not have a significant adverse impact on the environment, applications <strong>for</strong> renewable<br />

energy developments will be supported within areas of defined countryside (but outwith<br />

Green Belt area). Within areas of international conservation interest (as defined in para.<br />

2.64) renewable energy developments will only be allowed in the most exceptional<br />

circumstances where it can be demonstrated the overall integrity of the designated area<br />

will remain largely unaffected.’<br />

9.3.40 With regards to wind farm development in particular, Policy E12 states:<br />

‘The development of individual wind turbines of greater that 25Kw output, or wind farms<br />

will be considered favourably within areas of defined countryside (but outwith Green<br />

Belts areas) where all the following criteria can be met:<br />

a) the siting and external appearance of apparatus have been chosen to minimise the<br />

impact on amenity, while respecting operational efficiency;<br />

b) the development will not result in unacceptable intrusion into the landscape;<br />

c) access <strong>for</strong> construction and maintenance traffic can be achieved without<br />

compromising highway safety or causing unacceptable permanent and significant<br />

change to the environment;<br />

d) the development will have no significant detrimental effect on any designated<br />

heritage feature, including Listed buildings, Conservation Areas, Ancient<br />

Monuments, Historic Gardens and Designed Landscapes, Areas of Great<br />

Landscape Value and National Scenic Areas;<br />

e) the development will not affect the amenities of neighbouring occupiers<br />

unacceptably by reason of noise, visual dominance, shadow flicker, reflected light<br />

or other emission;<br />

f) no electromagnetic disturbance is likely to be caused by the proposal to any<br />

existing transmitting or receiving system or (where such disturbances may be<br />

caused) that measures will be taken to remedy or minimise any such interference;<br />

g) a realistic means of achieving the removal of any apparatus when redundant and<br />

the restoration of the site are proposed;<br />

Carron Valley Wind Farm<br />

h) no wind turbines should interfere with authorised aircraft activity or with the known<br />

regular flight paths of birds, particularly protected migratory species.’<br />

9.3.41 With regards to Areas of Great Landscape Value, Policy E15 states:<br />

‘a) the council will operate a presumption against developments within Areas of Great<br />

Landscape Value, with the exception of those required in relation to farming,<br />

<strong>for</strong>estry and appropriate tourist and recreation activities. Other developments may<br />

be permitted when their particular locational requirements cannot be satisfied<br />

elsewhere. All development will be subject to strict control other siting, design and<br />

landscape treatment.’<br />

9.3.42 With regards to Historic Gardens and Designed Landscapes, Policy E17 states:<br />

‘Developments within or affecting areas of Designed Landscape included within the<br />

Inventory proposed by Scottish Natural Heritage and Historic Scotland will require to be<br />

situated and designed to avoid an unacceptably adverse impact on the landscape.’<br />

9.3.43 In addition to the above policies, an alteration has been provided in Structure Plan Alteration<br />

1 – Renewable Energy (2004) by Clackmannanshire and Stirling Councils, of which Policy<br />

ENV 16: Wind Energy is most relevant:<br />

‘The strategic location and design of wind energy developments will be assessed<br />

against the following principles:-<br />

1. For overriding landscape character, built heritage and natural heritage conservation<br />

reasons, siting of wind turbines will not normally be acceptable in National Scenic<br />

Areas, in Green Belts or in the areas shown on the Structure Plan Renewable<br />

Energy Supplementary Key Diagram as ‘Exclusion Areas’. These areas are:<br />

• The Ochil Hills escarpment;<br />

• The Touch – Gargunnock – Fintry Hills escarpments (including Lewis Hill);<br />

• The Campsie Fells escarpments;<br />

• Queens View (Auchieneden);<br />

• Kippen Muir view;<br />

• The settings of Abbey Craig – Wallace Monument, Stirling Castle, Bannockburn<br />

Memorial and battlefield, and Sherrifmuir battlefield;<br />

• Flanders Moss.<br />

2. The remainder of the Structure Plan area will be regarded as an ‘area of search’ <strong>for</strong><br />

development opportunities. Scope within the National Park is expected to be limited<br />

and developments there should demonstrate that the objectives of the designation<br />

of the Park and the overall integrity of the area will not be compromised (see 3<br />

below).<br />

3. Within the ‘area of search; it will be <strong>for</strong> Local Plans, the National Park Plan and<br />

Supplementary Advice to set out all relevant consultation requirements and<br />

constraints. Local Plans will also further define the ‘Exclusion Areas’ and give<br />

guidance regarding development opportunities in ‘buffer zones’ around NSAs.<br />

4. The relationship of new proposals to established and approved developments and<br />

those that are currently the subject of undetermined applications. Proposals will not<br />

normally be acceptable where they would result in an adverse effect upon amenity,<br />

or features of scenic and/or heritage value, by reason of cumulative visual impact.’<br />

Stirling Landscape Sensitivity and Capacity Study <strong>for</strong> Wind Energy Development<br />

9.3.44 Horner + Maclenna was commissioned in July 2007 jointly by Stirling Council, Loch Lomond<br />

and the Trossachs National Park Authority and SNH to carry out a landscape and visual<br />

capacity study <strong>for</strong> wind energy development. The primary aim of the study is to determine the<br />

overall capacity of the Stirling Council area to accommodate wind farms and where the least<br />

adverse landscape and visual impacts would occur. The basis <strong>for</strong> the study area is land<br />

within the Stirling region which lies outwith the Loch Lomond and the Trossachs National<br />

Park. At the time of the study the wind farms which were under consideration included the<br />

following;<br />

• Braes of Doune – Existing;<br />

• Earlsburn – Existing;<br />

• Burnfoot – Consented;<br />

• Greenknowes – Consented;<br />

• Earlsburn extension – EIA in preparation;<br />

• Craigengelt – Submitted;<br />

• Muirpark - EIA in preparation;<br />

• Kingsburn - EIA in preparation;<br />

• Ballindalloch - EIA in preparation.<br />

9.3.45 However, conclusions within the report have mainly been based on a study area which<br />

includes Earlsburn in close proximity to the north, Braes of Doune approximately 23 km to the<br />

north and Burnfoot and Greenknowes in the Ochil Hills within the study area context and<br />

beyond the study area context respectively.<br />

9.3.46 The study included an assessment of landscape character to define distinct character types<br />

and determine sensitivity to wind farms, the visual resource and identification of sequential<br />

receptors including the B818 from Boquhan to Denny.<br />

9.3.47 The capacity of the landscape was assessed based on the following 7 criteria:<br />

Constraint<br />

• Landscape scale;<br />

• Distinctive hill edges;<br />

• Iconic landscape features;<br />

• Impacts of existing and consented windfarms.<br />

Sensitivity<br />

• Areas of landscape character incompatible with existing and consented windfarm sites;<br />

• Landscape pattern;<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

• Area valued <strong>for</strong> sense of remoteness while being easily accessed from an urban<br />

centre.<br />

Landscape Scale<br />

9.3.48 The study defines landscape scale as follows;<br />

‘The effect of landscape scale on capacity to accommodate wind energy development is<br />

principally manifested through the scale of topography and the shape of the land<strong>for</strong>m,<br />

as these affect visibility and contain spaces, in addition to the size of elements that<br />

make up landscape pattern, and how scale is experienced, <strong>for</strong> example through a sense<br />

of openness and exposure’.<br />

9.3.49 This particular constraint criteria relates principally to the perception of vertical scale provided<br />

by hill edges when seen adjacent to the flat landscape of the Forth Valley. The study regards<br />

that the addition of turbines into these views is likely to diminish the distinction between small<br />

and large scale landscape types. The study goes on to state that a particular characteristic of<br />

the landscape of the Stirling area is that the vertical scale of the hills is perceived as being<br />

large when in actual fact it is small. The identified area of constraint <strong>for</strong> turbines over 110 m<br />

high covers the whole study area.<br />

Distinctive Hill Edges<br />

9.3.50 These upland landscape are;<br />

‘highlighted by their strong contrast of slope, elevation, landuse and relation to adjacent<br />

land and lochs’<br />

9.3.51 The proposal site does not lie within the constraint area.<br />

Iconic Landscape Features<br />

9.3.52 The study area contains 8 iconic landscape features which are either based on historic sites<br />

and features of landscape character types.<br />

9.3.53 The proposal site does not lie within the constraint area.<br />

Impacts of Existing and Consented Windfarms<br />

9.3.54 The study supports the image of windfarms as ‘distinctive and isolated landscape features’<br />

which retain a buffer of land around them. Clustering of windfarms is considered, within the<br />

study, to create a confusing image that would dominate a landscape character type. Upland<br />

landscapes which <strong>for</strong>m a backdrop to the Forth Valley and those with a relationship with the<br />

edge of the Loch Lomond and the Trossachs National Park are considered, by the study, to<br />

be most sensitive.<br />

Areas of Landscape Character Incompatible with Existing and Consented Windfarm Sites<br />

9.3.55 The study reiterates opinions expressed <strong>for</strong> the ‘Impacts of Existing and Consented<br />

Windfarms’ constraint however, it also considers that ‘capacity of a landscape to<br />

accommodate additional windfarms is also affected by the relationship that existing<br />

windfarms have with a distinctive landscape character type if developments have been<br />

consistently located within that type’. The 4 existing and consented wind farms in the study lie<br />

within an area defined as ‘smooth hills’. The proposed wind farm would lie outside of this<br />

character area.<br />

9.3.56 The proposal site does not lie within the constraint area.<br />

Carron Valley Wind Farm<br />

Landscape Pattern<br />

9.3.57 Pattern in the landscape and its sensitivity is defined as follows;<br />

‘Areas of no obvious pattern or simple pattern are sensitive to the introduction of a<br />

windfarm as this may introduce a new pattern itself and thus contrast with the<br />

underlying simplicity. However, areas that possess distinct pattern are also sensitive to<br />

the addition of a windfarm, especially if the elements of that pattern are of a very<br />

different scale to wind turbines’.<br />

9.3.58 The landscape of the Carron Valley has an irregular pattern of reservoir and commercial<br />

<strong>for</strong>estry and a diverse topography of steep valley sides and open expanse of water. The<br />

study places the proposed wind farm site within the area defined as sensitive to wind farms in<br />

relation to landscape pattern as it concludes that the regular spacing of turbines would<br />

conflict with the irregular pattern and land<strong>for</strong>m.<br />

Area Valued <strong>for</strong> Sense of Remoteness while being easily accessed from an Urban Centre<br />

9.3.59 This area comprises the Fintry, Touch and Gargunnock Hills and the Campsie Fells and is<br />

defined in the study as follows;<br />

‘possessing a sense of retreat and remoteness derived from being located within an<br />

area of interior hills/moorland where views are mainly inward and the area is sparsely<br />

populated and not managed intensively’.<br />

9.3.60 The sites proximity to the large urban areas at Glasgow to the south extending round to<br />

Stirling in the north east and the inward looking and sparsely settled nature of Carron Valley<br />

would place the proposal site within this sensitive category. However, the dominance of<br />

commercial <strong>for</strong>estry and the presence of the reservoir rein<strong>for</strong>ce the areas’ managed and man<br />

made character.<br />

9.3.61 The study places the proposed wind farm site within the area defined as sensitive to wind<br />

farms in relation to a landscapes sense of remoteness whilst being easily accessible from<br />

urban areas.<br />

Landscape Character Types<br />

9.3.62 The study goes on to define landscape character types within the Stirling area and to provide<br />

descriptions and general windfarm siting and design guidance. The study area is divided into<br />

8 distinct character types. The proposals site lies within the Plateau Interior character type 6.<br />

Key guidance <strong>for</strong> windfarm development where capacity may exist is as follows;<br />

‘This character type has very limited capacity to accommodate wind energy<br />

development. This is partly because the extent of this landscape character type is quite<br />

small and partly because Earlsburn windfarm already <strong>for</strong>ms a very prominent focus from<br />

much of this landscape character type. This means that any further windfarm<br />

development would collectively seem to dominate this character type as no significant<br />

‘windfarm free’ area would seem to exist’.<br />

9.3.63 The study states that if capacity does exist the proposed wind farm would need to be<br />

designed as follows;<br />

• ‘Relate to the open character, medium scale and simple composition of this landscape.<br />

• Not located near the edges of the plateau area.<br />

• Not to conflict with the sense of remoteness and refuge within this landscape character<br />

type.<br />

• Appear concentrated and simple in <strong>for</strong>m.<br />

• Use turbines that appear the same size as others within a distinct area and follow a<br />

similar layout and image.’<br />

9.3.64 However, the study does recognise that ‘windfarms will not necessarily conflict with the<br />

recreational value of this landscape, as much of this is based on active pursuits’.<br />

Stirling Council Supplementary Planning Guidance: Interim Locational Policy and<br />

Guidance <strong>for</strong> Renewable Energy Development (Wind Turbines)<br />

9.3.65 In response to the Horner + Maclenna commissioned (2007) report, the Council resolved to<br />

adopt (with amendments) Planning Policies and Guidance on renewable energy (wind<br />

turbine) developments, to be deemed a material consideration <strong>for</strong> the determination of<br />

relevant planning proposals, on 17 th March 2011.<br />

9.3.66 The policies are based upon the staged approach to spatial frameworks in PAN45 Annex 2,<br />

and modified by the findings of the Horner + Maclenna (2007) report. ‘Areas of Significant<br />

Protection’, and ‘Areas of Search’ are identified in the interim SPG, albeit stating that:<br />

“Proposals, whether located within the identified areas of search with some scope <strong>for</strong><br />

development, in landscape terms, or not, will be assessed on their merits”. The proposed<br />

wind farm is located in an Area of Significant Protection.<br />

Wind Energy: General<br />

9.3.67 The first policy details the approach to wind energy development in general and outlines the<br />

‘areas of significant protection’ as follows:<br />

“ (1) Wind Energy: General<br />

a) Outwith ‘Areas of significant protection’ (see Policy Map 1) the Council will support<br />

proposals <strong>for</strong> wind turbines where:<br />

• they are appropriate in scale, design and layout <strong>for</strong> their location;<br />

• the landscape character and scale is capable of accommodating the scale of<br />

development proposed;<br />

• landscape, wildlife and habitats of international and national importance are not<br />

significantly adversely impacted;<br />

• historic heritage of national importance is not significantly adversely impacted;<br />

• construction and operation will not impact adversely on the water environment<br />

(including water supply catchments);<br />

• aviation and telecommunication interest’s can be protected;<br />

• significant detrimental effects upon nearby residential areas can be avoided.”<br />

9.3.68 All proposals <strong>for</strong> wind turbines will be assessed in relation to:<br />

• “technical and planning criteria established through national planning policy and<br />

guidance, principally the SPP and PAN45<br />

• locational and design guidance issued SNH<br />

Wind Energy: Visual and Landscape Impacts<br />

9.3.69 In terms of potential landscape and visual impacts Policy 2 states ‘the capacity of the plan<br />

areas to accommodate additional very large wind turbines (80 – 110 metres and<br />

>100 metres) is considered to be severely limited’.<br />

Wind Energy: Cumulative Impacts<br />

9.3.70 The SPG seeks to protect landscape and visual amenity by reason of cumulative impacts and<br />

states within Policy 3 ‘discrete wind farms will not be supported within zones identified on<br />

Policy Map 1 around existing wind farms’.<br />

Baseline Conditions<br />

Landscape Character<br />

9.3.71 As mentioned in the Methodology section, the landscape character of the study area was<br />

assessed as part of a national programme of landscape character assessment, carried out by<br />

SNH in partnership with local authorities and other agencies.<br />

9.3.72 In order that the baseline assessment of landscape character is consistent across the study<br />

area, and is considered at a level of detail appropriate to the location and scale of the<br />

proposed wind farm, a degree of synthesis has been necessary. This process has been<br />

in<strong>for</strong>med by SNH, the local authority and other agencies as well as field study over a number<br />

of months.<br />

9.3.73 The 35 km radius study area <strong>for</strong> the development is covered by the following assessments:<br />

• ASH Consulting Group, (1998), Clackmannanshire Landscape Character Assessment,<br />

9.3.74 At a more detailed scale, the differences within each of these character areas become<br />

apparent. The areas have been identified, located and described based on desk study and<br />

field observation.<br />

9.3.75 The SNH Landscape Character Assessments identified 60 generic character types within the<br />

35 km radius area of search. Following review of the descriptions within the text, it is<br />

considered that some of the character types are equivalent. As the site lies within the Central<br />

Region, the landscape character types within this landscape assessment have been used as<br />

the basis <strong>for</strong> all character types within the seven districts of the study area and the Loch<br />

Lomond and the Trossachs NP. These were subsequently correlated using similarities within<br />

the character to correspond with a manageable assessment of 16 character types designed<br />

by PfR’s consultants under the following titles:<br />

• Lowland River Valleys;<br />

• Lowland Plateau;<br />

• Lowland Plains;<br />

• Lowland Hills;<br />

• Lowland Hill Fringes;<br />

• Lowland Valley Fringes;<br />

• Lowland Loch Basins;<br />

• Coastal Margins;<br />

• Glen Sides;<br />

• Strath and Glen Floors;<br />

• Hills;<br />

• The Highland Boundary Fault Ridge;<br />

• Upland Ridge;<br />

• Upland Hills;<br />

• Upland Fringes.<br />

9.3.76 Table 9.10 below describes the corresponding 44 Landscape Character Areas within the<br />

35 km Study Area where the proposed wind farm will be visible (according to the ZTV maps<br />

produced). These areas are assessed in paragraphs 9.5.3 to 9.5.11 and 9.5.45 to 9.5.64.<br />

The dominant feature of this landscape is the Carron Valley Reservoir which nestles<br />

within and is enclosed by the volcanic rock masses of the Campsie Fells and<br />

Gargunnock, Fintry and Kilsyth Hills. The River Carron, which rises in the hills above<br />

Lennoxtown, has been dammed on its journey eastwards to create this long curving<br />

sweep of water. Along the southern edges numerous inlets interweave between<br />

jutting promontories, backed by the steep, mostly convex slopes of Meikle Bin<br />

(570m), Little Bin and Cock Hill. To the north the smoother, more rounded <strong>for</strong>ms of<br />

Cairnoch, Craigannet and Dundaff Hills drop down to the even, sweeping margins of<br />

the reservoir.<br />

The hillsides are covered almost entirely by mature coniferous plantations, which<br />

extend up to the edges of the reservoir, leaving only the peaks of Meikle Bin, Little<br />

Bin and Cairnoch Hill exposed.<br />

Along the northern edge of the reservoir narrow drifts of mixed and deciduous trees<br />

are scattered.<br />

Tumbledown stone walls, topped by post-and-wire fencing, line the roadside and<br />

enclose the rough grassland on the slopes of Craigannet Hill. On the western flank of<br />

Dundaff Hill, a distinctive group of shelterbelts is conspicuous.<br />

Only a few houses and farmsteads of varied styles dot the winding line of the B818<br />

along the northern perimeter, generally restricted towards the eastern end of the<br />

reservoir, leaving the hillsides uninhabited. The <strong>for</strong>est walks which run through the<br />

southern hillsides commence at the small parking area below Cock Hill, and are a<br />

popular recreational resource.<br />

The simple composition of water and af<strong>for</strong>ested hillside, combined with a lack of<br />

settlement and the position of the reservoir within the hills, creates a moderately<br />

remote atmosphere. The sweep of the reservoir leads the eye westwards towards<br />

the banded edge of the Fintry Hills and beyond, backed by the hazy profile of the<br />

Trossachs. The tight circle of hills and blanket coniferous woodland creates a<br />

powerful sense of enclosure, lessened only by glimpses westwards.<br />

As the River Carron leaves the Touch and Kilsyth Hills, it has carved deeply into the<br />

volcanic rocks, creating a narrow river valley with often precipitously steep sides,<br />

marked by the ripples and scars of soil creep and soil slip.<br />

The deep fissure of the river valley, cutting through low hills, produces views<br />

outwards and creates a strongly contained visual corridor. The bare soil, rocky<br />

outcrops and scrubby thickets, blending with feathery broadleaves, etch and stipple<br />

the base and sides of the valley, <strong>for</strong>ming a highly textured landscape of inaccessible<br />

and untouched character.<br />

Towards the head of the middle Endrick valley, west of its hill-top origin, the river is<br />

pinched between and dominated by the volcanic masses of the Fintry Hills to the<br />

north and the Campsie Fells to the south, be<strong>for</strong>e flowing westwards towards<br />

Drymen. The small, strongly meandering river runs across a near-flat valley floor,<br />

occasionally broken by gentle undulations, and enclosed by steeply rolling valley<br />

slopes. Many small streams cut through the hillsides and incise the southern tip of<br />

the plateau of Kippen Muir be<strong>for</strong>e merging with the Endrick Water.<br />

There are three small areas of this more extensive LCT that lie just within the<br />

National Park boundary to the west and south of the Lake of Menteith, encompassed<br />

by the Rednock Estate lands. It is generally similar in character to adjacent LCTs<br />

Rolling Farmland with Estates and Glen Floor Ridges and Knolls with Estates, where<br />

estate features and the distinctive aesthetics of designed landscapes dominate.<br />

The uppermost stretch of the valley of the Allan Water is bordered to the west by the<br />

eventually cutting through high, tightly enclosing slopes within a narrow cleft.<br />

The river valley is dominated by the parallel courses of several route corridors,<br />

including the broad sweep of the A9 trunk road and the railway line, and two smaller<br />

winding roads which lie lower down the valley. Towards the southern edge of the<br />

area these transport routes converge to <strong>for</strong>m a confusing network of major and minor<br />

floodplain of the River Forth to the east. A wide swathe of low, very gently rolling<br />

land stretches between the slopes of the Touch Hills and Denny Muir to the west and<br />

the flat floodplain of the Forth to the East. The lower stretches of the River Carron<br />

and its major tributary, the Bonny Water, run eastwards through the shallow,<br />

relatively flat open valley. To the north and south the ground rises gradually, the<br />

broad valley basin begin cupped by the fringes of the east Touch Hills and<br />

Slamannan Plateau.<br />

This Character type constitutes part of a larger unit which extends westwards into<br />

Stirling District and southwards across the Forth into Falkirk District.<br />

The immensely broad floodplain of the River Forth cuts a dramatic swathe from the<br />

Highland Boundary Fault in the west towards its confluence with the sea in the east.<br />

To the north, it merges with the related carselands of the Lower Devon, to the east<br />

The open floodplain of the lower Devon River bears a strong similarity to the<br />

neighbouring carselands of the Forth, into which the Devon discharges.<br />

South-west of Linlithgow the River Avon flows through a narrow, deep, sinuous,<br />

gorge-like valley with deep slopes on both the Falkirk and West Lothian banks. The<br />

Moorland<br />

The Plateau Moorlands consist of blanket bog, heather and grass moorland. The<br />

topography is comparatively level with extensive plateau basins rising to soft<br />

contoured ridges. A series of important transport corridors linking Glasgow and<br />

Edinburgh cross the plateau. The moorlands provide long views across the Glasgow<br />

conurbation, emphasising the contrast between the remote upland and the<br />

developed lowlands.<br />

A heavily-modified lowland plateau landscape which shelves gently eastward to<br />

merge gradually wit h the farmland plain of the lower Almond. A number of its<br />

southbank tributaries, including the Linhouse Water, Breich Water, Murieston Water<br />

and West Calder Burn <strong>for</strong>m narrow and deeply-incised features which link the upland<br />

fringe of the Pentlands to the Lowland Plain. To the east, igneous intrusions create a<br />

strongly rolling terrain which peaks at Dechmont Law (217m) to the north of<br />

Livingston .<br />

Areas of moorland occur both north and south of the Highland Boundary Fault Zone<br />

and <strong>for</strong>m part of the transitional zone between highland and lowland landscape<br />

character types. Moorland is important <strong>for</strong> open unspoilt characteristics and visual<br />

qualities associated with plateaus, a sense of altitude, extensive space, remoteness<br />

and wildness.<br />

Rolling Farmlands are distinguished from Plateau Farmlands by their lower altitude<br />

to spread north and east into Perth and Kinross District.<br />

The northern and western edges of the hills are dramatically defined by steep,<br />

precipitous slopes, topped by the exposed rock of horizontally banded lava flows.<br />

These basalt flows are notched deeply by a fault-line which demarcates the division<br />

between the Fintry and Gargunnock Hills. The cliff-edged plateau reaches its peak,<br />

at 485m, above Black Craig in the Gargunnocks. The hill-mass becomes less<br />

unified, the rock banding becoming fragmented and interspersed with isolated<br />

dolerite outcrops, as the Touch Hills drop down towards the east. Numerous streams<br />

and falls plunge sharply down the sheer, convex lower slopes, lending a markedly<br />

ribbed appearance to parts of the hill-flanks. Within the hill-plateau, several small-to<br />

medium-scale reservoirs are concealed in dips and depressions.<br />

The Campsie Fells <strong>for</strong>m part of the larger hill-group which also comprises the<br />

Gargunnock, Touch, Fintry and Kilsyth Hills. Lying on the south-west perimeter of<br />

Central Region, they comprise the highest ground within the grouping, rising to 578m<br />

at Earl's Seat. The dense mass of interwoven rounded hill-tops varies in profile to the<br />

north and south. Long ridges of rock extrude from the upper slopes of the<br />

Strathblane Hills, in contrast to the more broken silhouette created by the deep<br />

corries on the northern boundary of the Campsie Fells. Deep V-shaped valleys<br />

furrow the hillsides, holding minor watercourses which tumble down the fissured<br />

slopes.<br />

To the north of the Teith Valley, the rolling Braes of Doune gradually give way to the<br />

peaks of Uamh Bheag (665m) and Beinn Odhar which mark the northern boundary<br />

well-concealed reservoirs, and a more visually intrusive waterworks on the northern<br />

boundary of Darrach Hill.<br />

The northern and western perimeter of the discrete, rock-bounded mass of the<br />

Gargunnock and Fintry Hills is edged by an encircling, rippling belt of strongly rolling<br />

slopes. The fields are deeply incised by a multitude of burns, cutting downwards<br />

Coastal Flats<br />

A series of rolling, coastal hills about 100 to 150m ADD with a general down-slope to<br />

Bo'ness and the Firth of Forth. The town of Bo'ness lies mainly on the rising land of<br />

the hills which are topped by a golf course. The hills are crossed by the M9 and<br />

other major roads and railways.<br />

Around the coast of Fife there is a series of Coastal Hills mainly located above the<br />

Coastal Cliffs, braes, and terraces, which slope gradually towards the sea offering<br />

panoramic views of the Firths. Predominantly large, open, undulating arable fields,<br />

often with no field boundaries or wit h mainly wire fences, low hedges or some stone<br />

dykes and little other vegetation cover.<br />

Extending along the coast from the western edge of Edinburgh and inland towards<br />

Linlithgow, the gently rolling lowland terrain is interrupted by higher hills and ridges.<br />

Generally a simple, sloping, balanced, active, organised, tended, farming landscape<br />

with regular or geometric patterns. These hills mark the transition between coastal<br />

and landward areas of Fife sharing the characteristics of both.<br />

Coastal Flats are flat, low-lying, open, large-scale, exposed coastal landscapes at<br />

sea level. From the Coastal Braes and Hills, the Flats are seen as encroachments<br />

into the estuary.<br />

In general, the landscape is large-scale, open and exposed, uni<strong>for</strong>m and smooth or<br />

textured, flat with curved lines. It is a mostly balanced, still, organised, tended and<br />

quiet landscape. Where the Coastal Flats are more confined, either by buildings or<br />

vegetation, experiences tend to be of a smaller-scale landscape that is more diverse,<br />

rough and discordant, busier and more disturbed .<br />

Bounded by the Kincardine Bridge and the M 876 in the north west, and the M9 to<br />

the south west and Bo'ness to the east, this area of low lying coastal flats is<br />

dominated by the town of Grangemouth, the docks and by large-scale petrochemical<br />

Deep, U-shaped glens are characteristic features of the highland landscape. Straths<br />

are generally wider, but have still been influenced by glaciation. Straths and glens<br />

may be occupied by lochs or sea lochs, or have filled to some extent with sediment.<br />

Strath and glen floors in the larger, more open straths and glens are farmed where<br />

river deposition has <strong>for</strong>med sufficient flat land <strong>for</strong> agriculture. Whilst these <strong>for</strong>m a<br />

small proportion of the Park, they are significant in terms of their diversity of<br />

landscape and scenic character.<br />

The hill areas are north of the HBFZ and are composed of upland slopes, ridge lines,<br />

summits, and the upper reaches of upland glens. Typically the hill areas edge other<br />

upland and parallel ridges, moorlands or glen sides. On rare occasions, hill areas<br />

extend to glen floors, where rocky and typically upland slopes contrast dramatically<br />

with farmed strath floor or loch basins. These areas have significant scenic quality.<br />

Whilst hill areas do not rise above 1175m, they generally have a rugged character<br />

that belies their height.<br />

Parallel ridges <strong>for</strong>m prominent topographic features on the south-eastern margins of<br />

the HBFZ. The ridges are strongly orientated in a north-east to south-west direction<br />

giving a distinctive grain to the landscape, but do not rise above 500m.<br />

Diverse land<strong>for</strong>ms occur in this ground, including smooth moorlands, rocky outcrops,<br />

gullies and screes, within the unifying structure of ridges and intervening<br />

depressions. Burns and lochans are orientated along the depressions.<br />

The transition from the HBFZ to the north is less clearly defined, as the character of<br />

neighbouring uplands is similarly ridged and the area is intercut with glens and loch<br />

basins. This area is not so visually prominent and the ridges are somewhat obscured<br />

Visual Receptors<br />

Zone of Theoretical Visibility<br />

9.3.77 In order to determine available views and hence assess visual receptors and the visual<br />

amenity, a Zone of Theoretical Visibility (ZTV) has been mapped. The ZTV is the theoretical<br />

area from which part or all of the proposed wind farm is potentially visible and broadly defines<br />

the study area <strong>for</strong> both the character and visual assessment. The proposed ZTV is presented<br />

in Figures 9.3 to 9.6 and at a larger scale in combination with landscape designations within<br />

Figure 9.12 sheets 1 to 30.<br />

9.3.78 The ZTV <strong>for</strong> the proposal is relatively limited due to the location of the wind farm in a valley<br />

between areas of upland to the north and south. The ZTV in the vicinity of the site would<br />

extend south over the reservoir and <strong>for</strong>estry plantations of Carron Valley to the Kilsyth Hills.<br />

This range of hills lies approximately 4 km to the south of the proposals site and <strong>for</strong>ms the<br />

southern limit of the ZTV. The likely zone of visibility within areas of <strong>for</strong>estry would be<br />

significantly smaller than the ZTV shown, as trees are mature and mainly coniferous,<br />

screening many views. To the south west the Campsie Fells <strong>for</strong>m a continuation of this ridge<br />

and would <strong>for</strong>m the limit of the ZTV. To the west the ZTV would extend along the southern<br />

side of the Carron Valley beyond Fintry. To the north west the Fintry Hills rise up steeply<br />

<strong>for</strong>ming a scarp edge approximately 2 km from the proposals site and would <strong>for</strong>m the limit of<br />

the ZTV in the immediate vicinity of the site. To the north the ZTV would cover Hart Hill and<br />

the Gargunnock Hills beyond. To the east the ZTV would extend over Craigannet Hill,<br />

Craigengelt Hill, Dundaff Hill and the plateau landscape around Loch Coulter Reservoir,<br />

approximately 4 km from the proposal site. These landscapes <strong>for</strong>m the study area in the<br />

immediate context of the site.<br />

9.3.79 The ZTV within the remaining 35 km radius area of search would be relatively limited. To the<br />

east the ZTV would extend over a large area of the low lying landscapes either side of the<br />

River Forth estuary. The string of settlements from Cumbernauld in the south, via Denny to<br />

Dunblane in the north would <strong>for</strong>m the western extent of this area of the ZTV. The Ochil Hills<br />

would contain the ZTV to the north east. To the west the interlocking land<strong>for</strong>ms of the Fintry<br />

Hills and Campsie Fells would channel views to <strong>for</strong>m a narrow wedge of the ZTV, which<br />

would continue to the Loch Lomond and the Trossachs National Park on the edge of the<br />

35 km radius study area. Several small isolated areas of the ZTV would lie within upland<br />

areas of the National Park at the Menteith Hills and the peak of Ben Ledi, both to the north<br />

west of the site. Small areas of isolated ZTV would also exist to the north within the<br />

undulating landscape of the Forest of Glenartney, approximately 25 km to the north.<br />

9.3.80 A ZTV was produced <strong>for</strong> the wind turbine blade tips to establish an area of study within the<br />

35 km radius search area. Potential viewpoints and receptors were identified throughout this<br />

area and are shown on Figure 9.3. The methods and technical specifications used to<br />

generate the ZTV are detailed at Appendix 9.2. The ZTV illustrates the topography which<br />

may have a potential screening effect of the proposals from many parts of the study area.<br />

Local Level Study Area<br />

9.3.81 A local level study area has also been established to identify broadly where all of the visual<br />

receptors within a radius of approximately 2 km of the site lie.<br />

Residential Properties<br />

9.3.82 The photomontages relate to specific viewpoints and they illustrate the change in views from<br />

those locations. These receptors were chosen either to assess the significance of change<br />

from specific sensitive receptors, or as a representative view from a group of potential<br />

receptors. There are individual properties (outside the villages and towns) that might also<br />

have potential views. However, as with the other potential receptors, not all have been visited<br />

and assessed. Within towns or villages, although much of the area may have theoretical<br />

views based on the ZTV, the reality is that the outer edges of these settlements might have<br />

potential views, but that views from within the areas would not be available, as they would be<br />

screened by these ‘outer’ properties. Similarly residences may be screened by vegetation<br />

between the receptor and the wind farm. Occupiers of individual properties within a 2 km<br />

radius from the proposed wind farm have the potential to contain residents who may be<br />

significantly affected in EIA terms. Properties within a 2 km radius are identified on Figure<br />

Viewpoint 1. Todholes Bridge<br />

9.3.87 This is an open view across Endrick Water at a popular location <strong>for</strong> walkers beside the car<br />

park at the head of the Carron Valley Reservoir. The river cuts through the grazing pasture in<br />

the flat valley base. The bridge <strong>for</strong>ms a distinct feature in the <strong>for</strong>eground. Earth banks rise up<br />

to the left and right to frame the view of Cairnoch Hill beyond. Open deciduous woodland<br />

lines the water course at the base of the hill, whilst blocks of dense, uni<strong>for</strong>m conifer plantation<br />

covers the rising land. The crest of the hill remains open. Overhead power lines cross the<br />

<strong>for</strong>eground view and line the B818 to the right of the view.<br />

9.3.88 There are no significant sources of light that would be visible at night in this view.<br />

Viewpoint 2. Cringate Law<br />

9.3.89 This viewpoint is located within open moorland immediately adjacent to the wind farm at<br />

Earlsburn. The turbines in the <strong>for</strong>eground frame the view beyond towards the <strong>for</strong>ested<br />

land<strong>for</strong>ms of Cairnoch Hill and the Kilsyth Hills. The site is clearly visible in the centre of the<br />

view. The dark blocks of conifer plantations are interspersed with open grassland and<br />

moorland which <strong>for</strong>m a mosaic of muted colours and textures. The reservoir <strong>for</strong>ms a narrow<br />

expanse of water in the base of the Carron Valley.<br />

9.3.90 There would be no significant visible light sources within the view at night.<br />

Viewpoint 3. Minor Road near Earls Hill<br />

Viewpoint 4. Carron Valley Reservoir east<br />

9.3.93 This is a near partially constrained view looking north west from the B818, which is also<br />

representative of views from neighbouring residential properties. Native trees and shrubs<br />

along the shore of the reservoir are visible in the <strong>for</strong>eground. The land<strong>for</strong>m rises up to<br />

Craigannet Hill and the mature trees at Craigannet Crag to the north of the B818, <strong>for</strong>ming the<br />

horizon. To the left of the view the peak of Meikle Bin beyond <strong>for</strong>estry plantations surrounding<br />

the Carron Valley Reservoir <strong>for</strong>ms a backdrop to the view. Telegraph poles, lighting and<br />

signage <strong>for</strong>m some <strong>for</strong>eground visual clutter.<br />

9.3.94 A roadside lighting column and residential properties would <strong>for</strong>m limited sources of light<br />

within nighttime views.<br />

Viewpoint 5. Tomtain Hill<br />

9.3.95 This is an open, mid-distance view looking north west from the summit of Tomtain Hill in the<br />

range of Kilsyth Hills. Land in the <strong>for</strong>eground falls away steeply to the Carron Valley which<br />

cuts across the centre of the view. The land<strong>for</strong>m rises again beyond the reservoir in the valley<br />

base to <strong>for</strong>m the uplands at Fintry Hills, Cringate Law, Hart Hill and Earl’s Hill. The<br />

<strong>for</strong>eground comprises upland grassland and moorland with a scattering of conifer trees in a<br />

broad sweep along the crest of the hills. The sides of Carron Valley are covered by extensive<br />

blocks of conifer plantation within the Carron Valley Forest and at Cairnoch Hill. The existing<br />

wind farms at Earlsburn and Craigengelt <strong>for</strong>m prominent features within the grassland and<br />

moorland of the hills beyond. In the far distance the more extensive wind farm at Braes of<br />

Doune is visible on a range of hills. In the distance a series of ridgelines and hills within the<br />

Loch Lomond and the Trossachs National Park <strong>for</strong>m a distinctive backdrop to the view. The<br />

B818 and traffic moving along it are visible following the far shore of the reservoir.<br />

9.3.96 Traffic using the B818 and isolated residential properties would <strong>for</strong>m visible light sources in<br />

the view. The red warning lights on turbines at Earlsburn and Craigengelt <strong>for</strong>m relatively<br />

prominent features in a dark setting.<br />

Viewpoint 6. Carron Valley Reservoir south<br />

9.3.97 This is an open view from the southern shore of the reservoir looking across the expanse of<br />

water to Cairnoch Hill beyond. Access tracks within the <strong>for</strong>estry land provide recreational<br />

routes <strong>for</strong> walkers and cyclists and allow users to gain intermittent views towards the site.<br />

Grassland, marginal plants and deciduous scrub <strong>for</strong>m a band of native planting around the<br />

waters edge. Geometric blocks of conifer plantation clothe the undulating hillsides in the<br />

remaining view, <strong>for</strong>ming a distinctly managed landscape. Turbines within the Earlsburn and<br />

Craigengelt Wind Farms are visible on the horizon to the left and right of the view<br />

respectively. The turbines <strong>for</strong>m the main elements of development in the view. The B818 on<br />

the far side of the reservoir and the traffic upon it are also visible.<br />

9.3.98 Traffic using the B818 would <strong>for</strong>m light sources in the view beyond the reservoir. The red<br />

lights on turbines at Earlsburn and Craigengelt <strong>for</strong>m prominent features in a relatively<br />

landscape dark setting.<br />

Viewpoint 7. B822<br />

9.3.99 Where the road crosses the ridge of the Campsie Fells a view over open moorland towards<br />

cluster of buildings within the farmstead at Watershead is visible against the woodland edge.<br />

A series of hills stretches across the skyline from left to right incorporating the Fintry Hills,<br />

Hart Hill on which the Earlsburn Wind Farm <strong>for</strong>ms a focal point, Cairnoch Hill on which the<br />

site is located and Craigannet Hill. The alternating expanses of grassland and conifer<br />

plantation create a diverse backdrop to the view.<br />

9.3.100 Lighting within the farm buildings and warning lights on the turbines would <strong>for</strong>m the only light<br />

sources visible at night.<br />

Viewpoint 8. Fintry<br />

9.3.101 The view from the eastern edge of the village extends east over a <strong>for</strong>eground of rural<br />

farmland to more distant hills and <strong>for</strong>estry. Small scale pasture fields divided by post and wire<br />

fences and gappy, unmanaged hedgerows occupy the majority of the view in the flat valley<br />

base. Either side of the view the land<strong>for</strong>m rises to <strong>for</strong>m ridges of grazing land and dark blocks<br />

of plantation conifers. The alignment of the B818 is defined by mature trees and hedgerows<br />

and occasional houses with garden vegetation. Telegraph poles and overhead power lines<br />

are visible crossing the view. This view combines the attractive rounded shapes, light foliage<br />

and movement of native vegetation in the <strong>for</strong>eground with the uni<strong>for</strong>m, geometric <strong>for</strong>estry of<br />

the background.<br />

9.3.102 Residential properties scattered along the B818 and traffic using this road would be visible at<br />

night in a dark rural context.<br />

Viewpoint 9. Earl’s Seat<br />

9.3.103 The top of the hill at Earls Seat <strong>for</strong>ms an open elevated vantage point <strong>for</strong> views across a<br />

large part of the study area. The exposed undulating moorland of the Campsie Fells in the<br />

<strong>for</strong>eground is a complex mosaic of textures and colours. The distinctive scarp slope edge of<br />

the Fintry Hills plateau lies to the left of the view in front of the Earlsburn Wind Farm which<br />

<strong>for</strong>ms a prominent chain of turbines on the skyline. To the right of the view the land<strong>for</strong>m rises<br />

to <strong>for</strong>m the Kilsyth Hills which <strong>for</strong>m a high point at Meikle Bin. The site at Cairnoch Hill is<br />

visible in the centre of the view beyond a dip in the intervening land<strong>for</strong>m. The dark<br />

commercial conifer plantations contrast with the open moorlands of the surrounding<br />

landscape. The Craigengelt Wind Farm is visible beyond the crest of Cairnoch Hill. The ridge<br />

of the Ochill Hills <strong>for</strong>ms a distant backdrop to the view.<br />

9.3.104 There are very limited sources of light in this rural landscape. Warning lights on the turbines<br />

would <strong>for</strong>m the most prominent lights at night.<br />

Viewpoint 10. Balfron<br />

9.3.105 This view looking south east from the edge of the village of Balfron has a <strong>for</strong>eground of<br />

undulating arable farmland contained by a belt of mixed deciduous and coniferous trees.<br />

Large farm outbuildings are prominent in the <strong>for</strong>eground on the right of the view. Distant hills<br />

within the Campsie Fells frame the view to the right, providing a dramatic backdrop. Dark<br />

conifer plantations cover the base of the fells. The hills dip down below the level of the trees<br />

in the centre of the view at the head of the Carron Valley. To the left of the view the tops of<br />

the Fintry Hills are partially visible above the tree tops. This is a simple rural view with strong<br />

textures.<br />

9.3.106 There would be no obvious sources of light visible in a nighttime view.<br />

Viewpoint 11. Stirling Castle<br />

9.3.107 This is an open view from the viewing terrace of Stirling Castle looking south west. Stirling<br />

Castle <strong>for</strong>ms one of the eight Iconic Landscape Features identified in the ‘Stirling Landscape<br />

Sensitivity and Capacity Study <strong>for</strong> Wind Energy Development’. The elevation of the viewpoint<br />

above the surrounding flat, River Forth floodplain provides a unique opportunity <strong>for</strong> views<br />

across the landscape. In the <strong>for</strong>eground the <strong>for</strong>mal geometric layout of earthworks and lawns<br />

within the gardens of the castle grounds provide a context <strong>for</strong> the view. Beyond lies open<br />

farmland and a well treed golf course beside main distributor roads, the M9 corridor and the<br />

mixed residential and commercial development of the urban fringes of Stirling. In the distance<br />

the land rises to <strong>for</strong>m an upland range comprising the Touch and Gargunnock Hills. A mosaic<br />

of dense conifer plantations and open grassland and moorland extends over these hills to<br />

<strong>for</strong>m a backdrop to views. Within the centre of the view the Craigengelt Wind Farm and the<br />

telecommunications towers at Earl’s Hill are visible as prominent, although distant, features<br />

on the horizon. To the right of the view the blade tips of turbines within the Earlsburn Wind<br />

Farm are visible on the skyline. In the far distance to the right of the view lie the range of<br />

peaks within the Loch Lomond and the Trossachs National Park.<br />

9.3.108 Development on the edges of Stirling would <strong>for</strong>m the most prominent sources of nighttime<br />

lighting within the view. Traffic using the road network and street lighting would <strong>for</strong>m further<br />

sources of light. Red warning lights on the turbines and telecommunication towers on the<br />

horizon would also be prominent at night.<br />

Viewpoint 12. Wallace Monument<br />

9.3.109 The public viewing level at the top of the Wallace Monument allows framed views out<br />

between stone pillars over the surrounding diverse landscape and townscape. The Wallace<br />

Monument <strong>for</strong>ms another of the eight Iconic Landscape Features identified in the ‘Stirling<br />

Landscape Sensitivity and Capacity Study <strong>for</strong> Wind Energy Development’. The flat floodplain<br />

of the River Forth is visible in the <strong>for</strong>eground where the sinuous course of the river cuts<br />

through open grazing land. The town of Stirling occupies the majority of the scene, extending<br />

across the full width of the view. Residential and commercial development and the civic<br />

centre of the town <strong>for</strong>m a relatively dense urban mass. Stirling Castle, located on an outcrop<br />

of rock, is prominent in the middle distance in the centre of the view. Beyond Stirling the<br />

fringes of the settlement merge with farmland, golf courses and commercial <strong>for</strong>estry. The land<br />

continues to rise to <strong>for</strong>m an undulating horizon within the Fintry, Gargunnock and Touch Hills.<br />

Blocks of dark conifer plantation and areas of open moorland combine to <strong>for</strong>m a mosaic of<br />

colours and textures which cover these hills. The windfarms at Craigengelt and Earlsburn are<br />

prominent features on the horizon, together with telecommunications masts at Earl’s Hill.<br />

9.3.110 Extensive lighting associated with development and roads within Stirling would <strong>for</strong>m the most<br />

prominent sources of nighttime lighting within the view. Red warning lights on the turbines<br />

and telecommunication towers on the horizon would also be visible at night.<br />

Viewpoint 13. Dumyat Hill<br />

9.3.111 This viewpoint is located on the southern edge of the Ochil Hills which rise up steeply from<br />

the flat landscape of the River Forth flood plain. The <strong>for</strong>eground moorland dips out of site to<br />

reveal the expansive settled plain below. The River Forth <strong>for</strong>ms a sinuous water course which<br />

winds across this flat landscape linking the large town of Stirling via a series of smaller<br />

settlements to Grangemouth. The variety of urban pattern and grain is clearly visible<br />

interspersed with open space, woodland blocks and agricultural land. Traffic on motorways<br />

and main roads is visible in several locations within the valley. The Wallace Monument <strong>for</strong>ms<br />

a prominent vertical focal point in the <strong>for</strong>eground, rising up from a wooded hill. The land rises<br />

beyond the valley floor to <strong>for</strong>m a series of hills and ridges culminating in the Kilsyth Hills and<br />

Campsie Fells on the horizon. Woodland, commercial <strong>for</strong>estry and golf courses occupy the<br />

base of the hills, whilst moorland covers the upland areas. The steep scarp slope of the<br />

Gargunnock Hills <strong>for</strong>ms a distinctive hill edge feature in the landscape to the right of the view.<br />

The mountains of the Loch Lomond and the Trossachs National Park are visible in the<br />

distance to the right. A string of turbines at the Earlsburn Wind Farm are minor, although<br />

prominent features on the horizon. Telecommunication masts at Earls Hills are also visible<br />

against the sky. The wind farm at Craigengelt is less prominent mainly below the horizon in<br />

the centre of the view. Meikle Bin <strong>for</strong>ms a recognisable peak on the horizon in the centre of<br />

the view.<br />

9.3.112 At night the settlement of Stirling would contain numerous light sources, mainly on roads,<br />

which would <strong>for</strong>m the most prominent aspect of the view. The urban area would be clearly<br />

defined at night. Red warning lights on turbines and telecommunication towers in the distance<br />

would also be visible.<br />

Viewpoint 14. Cowie<br />

9.3.113 This is an open view looking south west from playing fields on the fringes of the village. The<br />

mown grass of the football pitches occupies the majority of the <strong>for</strong>eground. Low scrub and<br />

intermittent trees <strong>for</strong>m a naturalistic boundary to this open area which slopes down steeply<br />

out of view. Beyond lies an undulating landscape of arable farmland with blocks of woodland<br />

and mature trees along hedgerow boundaries. Pylon towers along an overhead power line<br />

are prominent vertical structures crossing this landscape. In the distance the land<strong>for</strong>m<br />

continues to rise at the Touch Hills and the Campsie Fells and Kilsyth Hills in the distance.<br />

Dark blocks of conifer plantation and pale moorland and grassland <strong>for</strong>m a mosaic of shapes<br />

on the upland areas. Turbines at Craigangelt Wind Farm <strong>for</strong>m distant although prominent<br />

structures on the horizon in the centre of the view. Telecommunication masts at Earls Hill to<br />

the right of this <strong>for</strong>m less significant vertical features on the horizon.<br />

9.3.114 Red warning lights on turbines and the masts would <strong>for</strong>m the most visible light sources in<br />

nighttime views in an essentially dark rural landscape.<br />

Viewpoint 15. Alloa Tower<br />

9.3.115 The rooftop viewing level of the historic Alloa Tower provides an elevated vantage point<br />

within the heart of the town. The canopies of trees which lie within the small parkland which<br />

surrounds the tower frame the <strong>for</strong>eground of views. Residential properties and a school are<br />

partially visible surrounding the park. The industrial fringes of the town dominate the majority<br />

of the view. Large scale warehouses and industrial buildings with slender stacks are located<br />

on the bank of the River Forth which is visible in the distance. Beyond the river lies the arable<br />

farmland of the river floodplains. Tree belts and woodland filter views of the low lying<br />

landscape beyond. As the land rises in the distance the land cover changes to <strong>for</strong>estry<br />

plantations and moorland. The Campsie Fells and Kilsyth Hills <strong>for</strong>m a horizon of undulating<br />

peaks, the highest of which is at Meikle Bin. The Craigengelt and Earlsburn Wind Farms are<br />

visible as very distant elements on the horizon to the right of Meikle Bin and partially<br />

obscured by the dominant vertical stacks in the <strong>for</strong>eground. The railway bridge and overhead<br />

power lines are more conspicuous elements of infrastructure in the middle distance. The<br />

stacks and plumes of industrial development at Cowie are prominent features in the middle<br />

distance visible against the dark hills.<br />

9.3.116 Lighting along roads and within buildings at Alloa in the <strong>for</strong>eground would create a well lit<br />

context <strong>for</strong> views at night. Settlements along the River Forth would create a secondary sky<br />

glow in the middle distance. Warning lights on the turbines and masts would <strong>for</strong>m minor<br />

visible light sources in the distance.<br />

Viewpoint 16. Slamannan<br />

9.3.117 This is an open view looking north west from public open space on the northern edge of the<br />

village. The mown grass of the football pitch occupies the <strong>for</strong>eground. A gently undulating<br />

landscape of mixed arable and pasture fields, subdivided by woodland belts and large blocks<br />

of conifer plantation extends into the distance. Farmsteads are prominent, scattered<br />

throughout this landscape. The chain of settlements linking Glasgow to Grangemouth are<br />

concealed in a broad valley in the landscape. In the far distance the land rises to <strong>for</strong>m the<br />

Campsie Fells and Kilsyth Hills. The steeply undulating land<strong>for</strong>m is covered by a combination<br />

of <strong>for</strong>estry and open moorland. The turbines within wind farms at Craigengelt and Earlsburn<br />

are distant although recognisable on the horizon.<br />

9.3.118 A limited number of light sources would be associated with the farmsteads and visible in a<br />

dark rural landscape. Warning lights on turbines would be visible in the distance.<br />

Viewpoint 17. Falkirk Wheel<br />

9.3.119 Following a site visit, the completion of photography and the preparation of wireline images it<br />

was found that the proposal would not be visible from this location. This viewpoint has<br />

there<strong>for</strong>e been discarded at the baseline data gathering stage and no further assessment has<br />

been undertaken.<br />

Viewpoint 18. West Highland Way<br />

9.3.120 This is a distant open view looking east across moorland on the fringes of the Loch Lomond<br />

and the Trossachs National Park. Watercourses cutting through moorland create a deeply<br />

fissured <strong>for</strong>eground which dominates the view. In the distance lies the high ground of the<br />

Campsie Fells, Fintry Hills and Gargunnock Hills and the distinctive hill edge <strong>for</strong>med by the<br />

escarpment slope. The tops of the Ochil Hills are visible in the distance to the left of the view.<br />

Farmland and <strong>for</strong>estry is visible in the middle distance covering the base of the hills and<br />

providing variety in the landcover. The tops of turbines within the Craigengelt Wind Farm are<br />

visible on the horizon as minor elements to the left of the view. Overhead power lines cross<br />

the entire view <strong>for</strong>ming prominent vertical elements of infrastructure in this otherwise<br />

relatively simple landscape. Colours are muted and textures rough in a predominantly rural<br />

view.<br />

9.3.121 Warning lights on turbines are likely to be the only sources of light that would be visible at<br />

night in this view.<br />

Viewpoint 19. Menteith Hills<br />

9.3.122 This distant view from the eastern edge of the Loch Lomond and the Trossachs National Park<br />

is open in nature due to the elevated moorland location of the viewpoint. The land<strong>for</strong>m drops<br />

away steeply to the low lying landscape of the River Forth valley base. The Lake of Menteith<br />

distance, <strong>for</strong>ming a subtle patchwork of greens and browns. Farmsteads and small<br />

settlements are scattered throughout this landscape. In the background the Touch,<br />

Gargunnock and Fintry Hills combine with the Campsie Fells to <strong>for</strong>m a distinctive upland area<br />

on the horizon, with some areas displaying particularly distinctive hill edges. Open moorland<br />

covers the steep scarp slope and relatively flat plateau. The Earlsburn wind farm <strong>for</strong>ms a<br />

distant, although recognisable feature on the horizon within the centre of the view.<br />

9.3.123 Nighttime light sources within properties and settlements would be relatively limited. The<br />

lights of vehicles using the local road network would also be visible and at times prominent.<br />

Warning lights on turbines at Earlsburn are distant and would not <strong>for</strong>m a significant element<br />

within nighttime views.<br />

Viewpoint 20. Ben Ledi<br />

9.3.124 This is a distant location on one of the highest peaks within the National Park which enables<br />

panoramic views over the study area to be gained. The <strong>for</strong>eground of rugged and rocky<br />

moorland with cairns falls away steeply to reveal commercial <strong>for</strong>estry plantations and<br />

moorland on the lower slopes and valley sides within the Park. The settlement of Callander<br />

<strong>for</strong>ms the most prominent concentration of development within the base of the wide open<br />

River Teith valley. A small section of the Lake of Menteith is visible in the base of the River<br />

Forth valley to the right of the view. The farmland and <strong>for</strong>estry of this broad and relatively flat<br />

valley base occupies a large proportion of the middle distance. The land rises beyond to <strong>for</strong>m<br />

the uplands of the Campsie Fells, Kilsyth Hills and the Fintry, Touch and Gargunnock Hills.<br />

The undulating <strong>for</strong>ms of these hills <strong>for</strong>m a distinctive backdrop to the right of the view.<br />

Earlsburn wind farm is visible although barely discernible on the skyline of these hills. To the<br />

left of the view the Ochill Hills <strong>for</strong>m a linear range of open uplands. The Braes of Doune wind<br />

farm <strong>for</strong>ms a distant although prominent feature in the Knaik Hills to the left of the view.<br />

9.3.125 Lighting at Callander and farmsteads and along roads would <strong>for</strong>m the main focus <strong>for</strong><br />

nighttime views in a dark rural landscape. Lighting on turbines would <strong>for</strong>m distant light<br />

sources within upland areas.<br />

Viewpoint 21. Conic Hill<br />

9.3.126 This is a distant open view looking east over an attractive rural landscape from a popular<br />

peak within the Loch Lomond and the Trossachs National Park. The <strong>for</strong>eground of upland<br />

moorland falls away steeply to merge with farmland comprising mixed arable and pasture<br />

fields defined by hedgerows and interspersed with woodland belts and blocks of dark conifer<br />

plantation. Beyond the gently undulating landscape of farmland the land rises as a series of<br />

hills and peaks <strong>for</strong>med by the Campsie Fells, Fintry Hills, Gargunnock Hills and the Ochil<br />

Hills. The tops of turbines within the Earlsburn Wind Farm <strong>for</strong>m a distant, although<br />

recognisable feature above the distinctive hill edge of the Gargunnock Hills beside the Forth<br />

Carron Valley Wind Farm<br />

Viewpoint 22. Meikle Bin<br />

9.3.128 This is a mid-distance open view looking north east from the peak of Meikle Bin, which<br />

adjoins the Kilsyth Hills. The <strong>for</strong>eground of moorland drops away steeply to reveal the<br />

relatively open, rounded crest of Little Bin. The curving expanse of water at the Carron Valley<br />

Reservoir <strong>for</strong>ms the focus of this view. The dense blocks of <strong>for</strong>estry plantation surround the<br />

reservoir, <strong>for</strong>ming an undulating and incised southern shoreline. The dark, geometric and<br />

uni<strong>for</strong>m conifer woodland contrasts with the open, pale mosaic of moorland. Cairnoch Hill<br />

occupies the centre of the view. The Fintry, Gargunnock and Touch Hills <strong>for</strong>m an upland<br />

plateau beyond on which lie the prominent wind farms at Earlsburn and Craigengelt. The<br />

River Forth plain stretches into the distance to the right of the view, with the Ochill Hills rising<br />

up to <strong>for</strong>m a mountainous backdrop. This is a highly managed landscape dominated by<br />

<strong>for</strong>estry and a man made water body, with focal points provided by wind farms.<br />

9.3.129 Traffic using the B818 and isolated residential properties would <strong>for</strong>m visible light sources in<br />

the view. The red warning lights on turbines at Earlsburn and Craigengelt <strong>for</strong>m relatively<br />

prominent features in a dark setting.<br />

proposed wind farm may be possible.<br />

9.3.131 The local road between the eastern edge of Balfron and the junction with the B818 passes<br />

through an agricultural landscape of mainly pasture fields divided by hedgerows and blocks<br />

of mixed woodland. The land<strong>for</strong>m is gently undulating and the road is generally orientated<br />

directly towards the proposal site. Hedgerows lie along both sides of the road, channelling<br />

views ahead. The presence of woodland and tree belts in the landscape obscures many<br />

wider views across the surrounding fields however, in several locations more distant views<br />

towards the Fintry Hills and Campsie Fells are possible and the entrance to the Carron Valley<br />

between the two upland areas.<br />

9.3.132 Turning left onto the B818 views open up as the landscape scale increases and woodland<br />

diminishes. The dip in the hills on the horizon where the Carron Valley is located is more<br />

pronounced. The Fintry Hills and Campsie Fells rise up steeply either side of the view,<br />

directing the eye towards the proposed wind farm site. Stone walls and low managed<br />

hedgerows define the road edges. There are still sufficient mature trees, tree belts and small<br />

blocks of woodland in the landscape to disrupt and fragment views into the distance. As the<br />

road approaches Fintry the landscape becomes more wooded and views towards the<br />

proposed wind farm site are generally obscured. Within the village houses and trees contain<br />

most distant views out of the settlement. East of this new part of Fintry views over the pasture<br />

of the flat valley base become more open and the church tower in the old part of Fintry<br />

becomes a focus in views. Passing through the older part of Fintry, buildings and trees<br />

continue to filter and fragment views. As the road crosses over the River Carron to the north<br />

side of the valley, views are contained by the steep valley side. The view eventually opens<br />

out where the valley base widens and the existing turbines of Earlsburn Wind Farm are<br />

visible on the horizon beyond a <strong>for</strong>eground of pasture farmland. These relatively open views<br />

continue to be gained as the road approaches the western end of the reservoir. The <strong>for</strong>estry<br />

covered land<strong>for</strong>m of Cairnoch Hill <strong>for</strong>ms a prominent feature in the <strong>for</strong>eground of views. As<br />

pasture land, more distant blocks of woodland and <strong>for</strong>estry plantation lie on higher ground.<br />

The proposed wind farm site is not visible at this point of the journey. Passing through a small<br />

cluster of properties at Muirmill, trees conceal views out from the road corridor. Further to the<br />

west as the view opens out Craigannet Hill <strong>for</strong>ms the horizon to the right, with the peak of<br />

Meikle Bin in the distance to the left beyond trees. Approaching the eastern end of the<br />

reservoir the engineered damn wall is visible in the <strong>for</strong>eground with the <strong>for</strong>ested slope of<br />

Meikle Bin rising up beyond. As the road follows the shore of the reservoir glimpses of the<br />

water are visible through trees. The proposed wind farm site is still not visible at this stage of<br />

the journey. As the land<strong>for</strong>m at Craigannet Hill dips towards the eastern edge of the site the<br />

conifer plantation becomes visible. As the road passes round the base of Cairnoch Hill and<br />

follows the shore of the reservoir an intermittent fringe of native vegetation is visible in front of<br />

dense blocks of plantation conifers within the proposal site. Views are generally directed<br />

across the open expanse of water at the reservoir to the range of <strong>for</strong>estry clad hills beyond<br />

including the peak at Meikle Bin. As the road continues north the open moorland of the Fintry<br />

Hills <strong>for</strong>ms a contrasting backdrop to views of the wooded Carron valley. Driving past the<br />

western boundary of the site conifers continue to confine views to the right and views are<br />

directs views over Loch Lomond. Heading east from the summit on the descent a 1 km<br />

stretch of the footpath would allow users to gain open views to the east. The landscape in the<br />

vicinity of Carron Valley would be visible in the distance beyond a <strong>for</strong>eground of hills and<br />

9.4 Topic Specific Design Evolution<br />

Overview of Design Development<br />

9.4.1 The site selection process and general site design considerations which defined the evolution<br />

of the proposed Carron Valley wind farm can be found within Chapter 3: Design Evolution.<br />

The following section concentrates on the specific landscape and visual resource issues<br />

which helped to establish the 15 turbine scheme assessed within the <strong>ES</strong>.<br />

Design Strategy<br />

9.4.2 An initial feasibility study considered land to the north and south of the reservoir <strong>for</strong> a<br />

potential wind farm. The initial design included a 77 turbine layout. The Landscape and Visual<br />

Feasibility Study undertaken in December 2010 concluded that the land at Cairnoch Hill<br />

should <strong>for</strong>m the focus of further design development.<br />

9.4.3 Environmental constraints mapping was undertaken to define a ‘Developable Area’ at<br />

Cairnoch Hill where an intermediate design <strong>for</strong> a theoretical 24 turbine layout was prepared.<br />

At this stage some preliminary input to define key landscape and visual considerations was<br />

undertaken ahead of a design workshop. The 24 turbine layout was rapidly reduced to 16,<br />

concentrating on the most desirable developable area to avoid likely significant effects on key<br />

landscape and visual receptors. An area predominantly on the southern and western slopes<br />

of Cairnoch Hill was identified which would support a compact and balanced layout of 16<br />

turbines.<br />

9.4.4 Key viewpoint locations were identified following the preparation of a blade tip ZTV. Wireline<br />

images were generated <strong>for</strong> the following strategic locations which were used to illustrate the<br />

various iterations of the 16 turbine layout;<br />

• Todholes Bridge (west of site) - In the vicinity of some of the closest residential<br />

properties. The scheme has been designed to limit adverse effects on sensitive<br />

receptors in this location.<br />

• Cringate Law (north of site) - A local high point in the vicinity of the Earlsburn Wind<br />

Farm.<br />

• Carron Valley reservoir (east of site) - Representative of the closest residential<br />

properties to the east. The scheme has been designed to limit adverse effects on<br />

sensitive receptors in this location.<br />

• Meikle Bin (south of site) - The highest peak in the vicinity of the site. The elevated<br />

location allows unhindered views of the Earlsburn and Craigengelt wind farms and has<br />

enabled the design to be adapted to respond to the context and limit effects on the<br />

AGLV.<br />

• Stirling Castle - This receptor has been chosen to ensure turbines are not visible from<br />

this key location.<br />

• West Highland Way, Loch Lomond and the Trossachs National Park - This location<br />

within a nationally designated landscape has been chosen to ensure turbines sit below<br />

the level of surrounding uplands and are not prominent in views.<br />

9.4.5 The first four viewpoint locations are in relatively close proximity to the site and allow open<br />

views of the turbine layout to be analysed. Stirling Castle was a key receptor identified<br />

through consultation and would potentially gain mid-distance views of the proposals to the<br />

north east of the site. Turbines have been sited on lower ground within the site to conceal the<br />

wind farm in views in the context of distinctive hill edges from an important destination and<br />

viewing point. The view from the National Park is more distant however, it was considered<br />

important to test scheme visibility from this nationally important landscape. The turbines have<br />

been located to be discrete in the landscape.<br />

9.4.6 A series of layouts using the 16 turbines were examined through an iterative design process.<br />

The design criteria used to in<strong>for</strong>m the process were as follows;<br />

• A simple and compact <strong>for</strong>m which has a unified appearance. Turbines have been<br />

designed to have a similar spacing within the wind farm to avoid a random<br />

appearance.<br />

• Avoidance of outlier turbines and visual stacking. The organised composition of the<br />

wind farm prevents single turbines appearing as separated from the main cluster.<br />

Straight lines have been avoided to prevent views of several turbines on the same axis<br />

which is discordant in the landscape.<br />

• Relationship of the wind farm to the character, scale, pattern and composition of the<br />

landscape. The scale of the wind farm and its shape have been designed to relate well<br />

to the scale and shape of the reservoir and the land<strong>for</strong>m of Cairnoch Hill.<br />

• Potential conflicts with sense of remoteness.<br />

Carron Valley Wind Farm<br />

• Relationship of turbines with backdrop and horizon. Turbines have been located away<br />

from distinctive hill edges and scarp slopes of the plateau landscape. When visible<br />

turbines would often be visible below the horizon line or level of the surrounding hills.<br />

• Relationship with existing wind farm turbine size, scale and layout. Turbine size would<br />

be consistent with neighbouring schemes at Earlsburn and Craigengelt and the wind<br />

farm scale would be similar to these schemes. The visual separation between the 3<br />

schemes would be maintained.<br />

9.4.7 Following the identification of potential impacts on the setting of Sir John de Graham’s Castle<br />

Scheduled Monument a second design workshop took place. A turbine was removed and the<br />

15 remaining turbines were repositioned within the developable area.<br />

9.4.8 In addition to turbine layout the location of wind farm infrastructure has also been considered<br />

in the design process. The felling of trees to accommodate the turbines, access tracks and<br />

borrow pits have been incorporated into the Forest Design Plan prepared by FCS. The<br />

integration of the wind farm in a landscape of commercial <strong>for</strong>estry and the potential <strong>for</strong><br />

enhancement of the conifer plantations through diversification of species and structure would<br />

<strong>for</strong>m part of the ongoing, long term management of the <strong>for</strong>estry.<br />

9.5 Potential Significant Effects of the Scheme<br />

Construction<br />

Activities Associated with the Construction Phase<br />

9.5.1 The construction phase of the proposed wind farm is likely to take approximately 20 months.<br />

The following construction phase activities have been considered:<br />

• Felling of trees within Forestry Commission land to accommodate wind farm<br />

infrastructure;<br />

• Preparation of the temporary construction compound and erection of temporary site<br />

portable buildings;<br />

• Upgrading of existing site entrances and access tracks and construction of new access<br />

tracks between the wind turbines, control building and construction compound;<br />

• Construction of crane hard standing areas;<br />

• Excavation of wind turbine foundations and construction of wind turbine bases;<br />

• Excavation of cable trenches and laying of power and instrumentation cables;<br />

• Construction of control building and installation of electrical equipment;<br />

• Erection and commission of wind turbines;<br />

• Reinstatement works to access tracks, crane hard standings and temporary<br />

construction compound;<br />

• Re-grading of levels to accommodate wind turbine foundations; and<br />

• Excavation and filling of borrow pits.<br />

Carron Valley Wind Farm<br />

Effects on Landscape Resources During the Construction of the Wind Farm<br />

Methodology<br />

9.5.2 The assessment of construction effects is based on the methodology detailed in Section 9.2<br />

of this chapter. In summary the value of the landscape resource (based on designations) and<br />

its sensitivity to the proposed construction operations is considered in relation to the<br />

magnitude of the proposed change to the landscape resource’s fabric and character. The<br />

importance of the change to the landscape resource can then be assessed. The construction<br />

phase of the wind farm is considered to be temporary in nature. The matrix at Table 9.8 is<br />

used to establish a preliminary significance of effect based on sensitivity and magnitude. The<br />

effects are then generally downgraded to reflect their temporary nature and to provide a<br />

comparison with the permanent operational effects of the development. The effects on the<br />

individual character types are set out in detail at Appendix 9.6.<br />

Landscape Character: Direct Effects<br />

9.5.3 The likely effects on the landscape fabric and character during the construction phase are<br />

described in tables at Appendix 9.6.<br />

9.5.4 The proposed wind farm would be located within the Upper Carron Lowland River Valleys<br />

character type. The creation of the construction site and activities which would take place<br />

within it would result in direct short term effects on the character of the landscape. Felling<br />

operations associated with the clearance of conifer plantation to accommodate the turbines,<br />

crane pads, borrow pits and access tracks and anemometry mast would involve the removal<br />

of a typical feature of the landscape character type. These works would be typical practices<br />

within a commercially managed <strong>for</strong>est. The high level turbine erection activities and the<br />

presence of cranes within the landscape would be discordant within the Carron Valley.<br />

Although conspicuous within the landscape the activities would be temporary. The sensitivity<br />

of the landscape during this period would be medium and the magnitude of change also<br />

medium, resulting in a Slight effect during the day which is not significant.<br />

9.5.5 There would be no significant lighting requirements at the site during the construction phase.<br />

The nighttime effects would be negligible in magnitude and thus not significant. This<br />

assessment also holds true <strong>for</strong> all other character types and so is not assessed further below.<br />

Landscape Character: Indirect Effects<br />

9.5.6 The Fintry, Gargunnock and Touch Lowland Hills character type lies immediately to the north<br />

of the Upper Carron Valley and provides important landscape context to the proposal. The<br />

construction site and activities would <strong>for</strong>m a prominent feature in the context of this<br />

landscape character type, which would have an influence over the landscape character.<br />

Turbine erection, cranes, ground level infrastructure construction, site traffic and tree felling<br />

operations would combine to <strong>for</strong>m a prominent and discordant addition to the landscape in<br />

the short term, immediately adjacent to the edge of the character type. The sensitivity of the<br />

landscape would be medium and the magnitude of change medium, resulting in a Slight nonsignificant<br />

effect.<br />

9.5.7 The Campsie Fells Upland Hills and Campsie Fells Lowland Hills character types are two<br />

further character types which lie adjacent to the Carron Valley. The ridge of hills to the south<br />

of the proposal site would <strong>for</strong>m the backdrop to the construction activities. The commercial<br />

<strong>for</strong>estry of the reservoir fringes within the character types has a similar appearance to land at<br />

Cairnoch Hill within the construction site. The elevated nature of the land<strong>for</strong>m provides<br />

opportunities <strong>for</strong> views out from these hills including most aspects of the construction<br />

activities. The construction site and in particular the high level activities and cranes would<br />

<strong>for</strong>m a prominent addition to the landscape in the context of the character types. The<br />

sensitivity of the landscape and the magnitude of the temporary change would be medium<br />

leading to a Slight effect during the day which is not significant.<br />

9.5.8 The Middle Endrick Water Lowland River Valleys character type lies to the west of the Carron<br />

Valley. The high level construction activities would be visible from relatively large parts of the<br />

lowland farmed landscape. The sensitivity of the landscape and the magnitude of change<br />

would be medium, resulting in a Slight non-significant effect.<br />

9.5.9 The Middle Carron Lowland River Valleys character type and the Denny Muir Lowland Hill<br />

Fringes character type lie adjacent to the character type in which the construction site would<br />

be located. These landscapes <strong>for</strong>m a corridor of farmland, moor and woodland and would<br />

have limited views of the high level construction activities. The sensitivity of these landscapes<br />

would be medium and the magnitude of change small. The temporary effect would be<br />

Negligible which is not significant.<br />

9.5.10 Other landscape character types which lie within a zone of the study area between 5 km and<br />

35 km from the proposals site would be defined as either Lowland, Coastal or Upload<br />

character areas. They are located mainly to the east of the site between the Ochil Hills in the<br />

north and the West Lothian Plateau in the south. Only limited aspects of the high level<br />

construction activities would be visible above intervening hills which surround the Carron<br />

Valley. The sensitivity of these landscapes is medium or negligible and the magnitude of<br />

change would be small to negligible, resulting in a Negligible effect during the day and at<br />

night, which is not significant.<br />

9.5.11 Six landscape character types within the Highland character area are located within the Loch<br />

Lomond and the Trossachs National Park. These landscapes are located between<br />

approximately 20 km to 35 km from the construction site and are of high scenic quality.<br />

However, the long distances and sense of separation between the construction activities and<br />

the character types would limit the influence the temporary works would have over these<br />

landscapes. These landscapes would have a high sensitivity, would temporarily experience a<br />

small magnitude of change and a Negligible effect, which is not significant.<br />

Effects on Visual Receptors During the Construction of the Wind Farm<br />

9.5.12 The extent of visibility of the existing site would increase considerably during the construction<br />

phase of the wind farm due mainly to the introduction of high level cranes into the site. The<br />

cranes would be visible above the surrounding trees and woodland which screens the<br />

majority of the existing site area.<br />

Local Level Study Area<br />

9.5.13 Residential visual receptors within a radius of approximately 2 km <strong>for</strong>m a local level study<br />

area and are all defined as being of high sensitivity. The effect on their views is described<br />

below. A residential amenity assessment has not been undertaken <strong>for</strong> these properties as it<br />

is considered that sufficient detail regarding effects on the views of occupiers has been taken<br />

into consideration and that no overbearing or oppressive effects are likely to occur.<br />

Reference to the Planning <strong>Statement</strong>, which accompanies this <strong>ES</strong>, provides further<br />

justification <strong>for</strong> this approach.<br />

Residential Properties<br />

9.5.14 Mature conifers surround the two pairs of semi detached houses at Gartcarron on the B818<br />

approximately 600 m west of the site (approximately 1.5 km from the nearest proposed<br />

turbine (Turbine 5)). Views of high level construction activities would be largely obscured by<br />

trees. The oblique, temporary views of works would be negligible in magnitude resulting in<br />

effects which would be Negligible overall and not significant. Near views of the construction<br />

activities would be gained by occupiers of Todholes Farm north of Randie<strong>for</strong>d Bridge<br />

approximately 300 m west of the site (approximately 1.2 km from the nearest proposed<br />

turbine (Turbine 5)). Views over grassland and woodland of mainly high level turbine erection<br />

works and cranes would be gained by residents. The prominent, temporary addition to views<br />

would be large in magnitude, resulting in a Major effect which is significant in terms of the EIA<br />

Regulations.<br />

9.5.15 Five pairs of semi detached bungalows and houses on the B818 at Craigannet approximately<br />

1.3 km east of the site (approximately 1.4 km from the nearest proposed turbine (Turbine 15))<br />

are located at the base of the hill, whilst Craigannet and Easterton Farms at the base of<br />

Craigannet Hill lie approximately 1.4 km and 1.7 km respectively east of the site<br />

(approximately 1.5 km and 1.8 km respectively from the nearest proposed turbine (Turbine<br />

15)). Limited views of high level construction activities would be gained by residents in these<br />

three properties. The magnitude of change in view would be negligible, resulting in a<br />

Negligible and non-significant effect. Six properties on the B818 at Muirmill approximately<br />

2.1 km east of the site (approximately 2.2 km from the nearest proposed turbine (Turbine 15))<br />

and Drum Farm at the base of Dundaff Hill approximately 1.7 km to the east of the site<br />

(approximately 2.3 km from the nearest proposed turbine (Turbine 15)) are surrounded by<br />

scattered mature trees. Views of high level construction activities on the eastern edge of the<br />

site would be heavily filtered by intervening trees, limiting the magnitude of change to<br />

negligible and the significance of effect to a Negligible and non-significant effect.<br />

9.5.16 Easter Cringate Cottage lies 2.2 km north east of the site in an open moorland location<br />

(approximately 2.6 km from the nearest proposed turbine (Turbine 2)). Residents would gain<br />

open views over the landscape and conifer plantations of high level construction activities,<br />

including cranes, behind Cairnoch Hill. The magnitude of change would be medium and the<br />

significance of effect would be Moderate. Occupiers of single storey properties at Easter<br />

Cringate and Cairnoch Lodge, which lie 600 m and 550 m north, respectively of the site<br />

(approximately 1.1 and 1 km respectively from the nearest proposed turbine (Turbine 3))<br />

would have filtered views through trees of high level construction activities rising out of<br />

<strong>for</strong>estry on Cairnoch Hill. The magnitude of change would be small and the significance of<br />

effect would be a Slight and non-significant effect. Cringate lies beside the Endrich Water<br />

valley approximately 500 m north of the site (approximately 800 m from the nearest proposed<br />

turbine (Turbine 1)). The land<strong>for</strong>m channels views immediately south. The construction site<br />

and activities would be prominent in views with a backdrop of the reservoir, <strong>for</strong>estry beyond<br />

and Meikle Bin. The magnitude of change would be medium resulting in a Moderate and nonsignificant<br />

effect. Further up the valley at the base of Ling Hill lies Burnfoot, approximately<br />

1.8 km to the north of the site (approximately 2.2 km from the nearest proposed turbine<br />

(Turbine 1)). Views would be channelled towards the wind farm construction site and<br />

activities beyond a <strong>for</strong>eground of turbines at Earlsburn. The construction activities would<br />

some opportunities <strong>for</strong> views towards the proposal site. In several locations around the base<br />

of Haugh Hill, framed views from clearings would be gained towards the wind farm<br />

construction site and activities. The turbine erection activities and cranes in particular would<br />

<strong>for</strong>m prominent temporary elements in views. The magnitude of change would be large<br />

leading to Major effects <strong>for</strong> walkers which is significant, and Slight effects <strong>for</strong> cyclists and<br />

drivers which are not significant.<br />

Viewpoint Analysis<br />

9.5.18 The visual impact assessment has concentrated deliberately on receptors of the highest<br />

sensitivity to change, including occupiers of residential properties and users of public access<br />

land and rights of way within a 35 km radius of the site. The significance of effect on these<br />

receptors of the construction phase activities at the wind farm site is dealt with in relation to<br />

22 specific viewpoint locations described at paragraphs 9.5.19 to 9.5.40. below. The likely<br />

effects on these visual receptors during the construction phase are also summarised at<br />

Appendix 9.7.<br />

Viewpoint 1. Todholes Bridge<br />

9.5.19 During the construction phase the activities at the site would become the new focus of the<br />

view. The activities associated with the erection of the turbines, including cranes, would be<br />

visible on the slopes of Cairnoch Hill. These high level activities would be seen as prominent<br />

new elements on the skyline, above the blocks of conifer plantation. The felling of trees to<br />

accommodate turbines, access tracks and borrow pits would be apparent however the<br />

temporary and permanent infrastructure itself would be concealed by the extensive area of<br />

retained <strong>for</strong>estry. The sensitivity of walkers at this location is high and the magnitude of the<br />

temporary change in view they would experience would be large, resulting in a Major effect<br />

which is significant.<br />

Viewpoint 2. Cringate Law<br />

9.5.20 From this location on rising land to the north of the proposed site the construction activities<br />

would be prominent located on the western side of Cairnoch Hill beside the reservoir,<br />

although the turbines at the Earlsburn Wind Farm would continue to be very prominent in the<br />

<strong>for</strong>eground of the view. Turbine erection activities and cranes would <strong>for</strong>m discordant<br />

elements in the valley landscape of the river Carron, currently dominated by conifer<br />

plantations. The tree felling operations associated with construction of wind farm<br />

infrastructure at the site would be generally characteristic of management operations within a<br />

commercial <strong>for</strong>est. Crane pads, borrow pits and track construction would be visible in more<br />

open areas of the plantation. The sensitivity of receptors would be high and the magnitude of<br />

change as a result of the construction activities would be medium, resulting in a Moderate<br />

and non-significant effect.<br />

Viewpoint 3. Minor Road near Earls Hill<br />

9.5.21 The high level wind farm construction activities would be seen beyond the brow of Cairnoch<br />

Hill which <strong>for</strong>ms an undulating land<strong>for</strong>m in the middle distance and against a distant backdrop<br />

of the Campsie Fells. The turbine erection activities and cranes would temporarily become a<br />

prominent addition to the view. The construction site and ground level activities would be<br />

concealed by <strong>for</strong>estry and land<strong>for</strong>m. The sensitivity of occupiers of vehicles would be medium<br />

and the sensitivity of walkers would be high. The magnitude of change would be small <strong>for</strong><br />

both receptor groups leading to a temporary Negligible effect <strong>for</strong> occupiers of vehicles and<br />

Slight effect <strong>for</strong> walkers, neither of which are significant.<br />

Viewpoint 4. Carron Valley Reservoir east<br />

9.5.22 Glimpses of high level construction activities and cranes would be visible on the skyline<br />

above the rising land<strong>for</strong>m and woodland of Craigannet Hill. The activities would not be<br />

immediately apparent and could be easily missed by receptors at the eastern end of the<br />

reservoir. Occupiers of properties and walkers would be of high sensitivity, although the<br />

negligible magnitude of change would temporarily result in a Negligible and non-significant<br />

effect.<br />

Viewpoint 5. Tomtain Hill<br />

9.5.23 The elevated nature of the summit of Tomtain Hill provides opportunities <strong>for</strong> open views over<br />

Carron Valley to the mountains of the Loch Lomond and the Trossachs National Park on the<br />

distant horizon. The construction site <strong>for</strong> the proposed wind farm would be visible on the<br />

south west flank of Cairnoch Hill adjacent to the reservoir. Many aspects of the construction<br />

phase would be visible in this panoramic view and would temporarily <strong>for</strong>m discordant<br />

elements in the landscape. Turbine erection activities and the presence of cranes would be<br />

the most prominent additions to the view. Borrow pit, crane pad and access track<br />

construction would also be visible although less prominent within the retained mosaic of<br />

conifer plantation. The sensitivity of receptors in this location is high and the magnitude of<br />

change would be medium resulting in a Moderate and non-significant effect.<br />

Viewpoint 6. Carron Valley Reservoir south<br />

9.5.24 Open views across the reservoir from recreational tracks within the <strong>for</strong>estry would focus on<br />

the prominent wind farm construction activities. The turbine erection activities and cranes<br />

would be visible on the slopes of Cairnoch Hill, against the undulating skyline, in a landscape<br />

of conifer plantation and open <strong>for</strong>estry land. Borrow pit, crane pad and access track<br />

construction activities would be visible although partially concealed by the retained blocks of<br />

conifer plantation. The temporary construction activities would <strong>for</strong>m a discordant addition to<br />

the view. Walkers would be of high sensitivity to the large magnitude of change in view<br />

leading to a Major effect, which is significant. Cyclists would be of medium sensitivity and<br />

would experience a Moderate and non-significant effect.<br />

Viewpoint 7. B822<br />

9.5.25 High level construction activities associated with the wind farm would be visible with respect<br />

to all turbines in the proposed wind farm. The construction site and some ground level<br />

activities would be visible on the slopes of Cairnoch Hill. Tree felling activities to<br />

accommodate the turbines would be generally characteristic of ongoing management<br />

practices <strong>for</strong> commercial <strong>for</strong>estry. The sensitivity of occupiers of vehicles using the B822<br />

would be medium and the temporary magnitude of change in view would also be medium,<br />

leading to a Slight and non-significant effect.<br />

Viewpoint 8. Fintry<br />

9.5.26 A small section of the high level construction activities and cranes would be visible on the<br />

horizon at the head of the Carron Valley. Conifer plantations and woodland fringes in the<br />

intervening view would conceal further elements of the wind farms construction. Occupiers of<br />

properties on the eastern edge of the village are receptors of high sensitivity. The small<br />

magnitude of change would result in a Negligible and non-significant effect.<br />

Viewpoint 9. Earl’s Seat<br />

9.5.27 The majority of the Carron Valley wind farm construction site and activities would be visible<br />

on the slopes of Cairnoch Hill in the mid distance view. High level turbine erection activities<br />

would be prominent in the view, although would be visible below the horizon. Borrow pit,<br />

crane pad and access track construction activities would be barely perceptible due to the<br />

screening effects of the retained conifer plantation. Walkers in this location would be<br />

receptors of high sensitivity, experiencing a small magnitude of change that would<br />

temporarily result in a Slight and non-significant effect.<br />

Viewpoint 10. Balfron<br />

9.5.28 Only glimpses of the high level construction activities would be visible through the tree tops of<br />

an intervening woodland belt on the edge of the village. The tops of turbines and cranes<br />

would be barley perceptible and the character of the predominantly rural view would be<br />

maintained. Receptors would be of high sensitivity and the magnitude of change would be<br />

negligible, which would temporarily result in a Negligible and non-significant effect.<br />

Viewpoint 11. Stirling Castle<br />

9.5.29 Following the preparation of wirelines <strong>for</strong> this viewpoint it became apparent that no part of the<br />

proposed construction activities would be visible from this location at Stirling Castle.<br />

Viewpoint 12. Wallace Monument<br />

9.5.30 The tops of turbines and cranes <strong>for</strong> a small section of the wind farm construction activities<br />

would theoretically be visible from this location. The barely perceptible nature of the<br />

proposals would <strong>for</strong>m a negligible change in views from the Wallace Monument. The effect<br />

would be Negligible and there<strong>for</strong>e not significant.<br />

Viewpoint 13. Dumyat Hill<br />

9.5.31 The high level turbine erection activities and cranes at some locations within the Carron<br />

Valley wind farm would be visible as barely perceptible additions to the view below the<br />

horizon of the distant hills. The temporary activities would <strong>for</strong>m a very minor addition to the<br />

view. The high sensitivity of walkers and the negligible magnitude of temporary changes in<br />

this distant view would temporarily result in a Negligible and non-significant effect.<br />

Viewpoint 14. Cowie<br />

9.5.32 The tops of 5 turbines and the cranes associated with their erection would temporarily <strong>for</strong>m<br />

barely perceptible additions to the view beyond Craigengelt Wind Farm. Receptors in this<br />

location would be of high to medium sensitivity, experiencing a negligible magnitude of effect,<br />

which would result in a Negligible to and non-significant, effect.<br />

Craigengelt Wind Farm in the context of extensive and dominant industrial and commercial<br />

development on the banks of the river Forth in the <strong>for</strong>eground. The activities would be very<br />

a recognisable new element within the view the construction activities would not be<br />

prominent. The magnitude of change and resulting effect would be negligible and would not<br />

distant, although recognisable new element in the view crossing the ridge of hills in the<br />

distance. Low level infrastructure construction activities would be barely perceptible at this<br />

distance. The temporary activities would <strong>for</strong>m a new focus within distant views however, the<br />

magnitude of change at this distance would be small. The high sensitivity receptors would<br />

experience a small magnitude of change resulting in a Slight and non-significant, effect.<br />

Viewpoint 19. Menteith Hills<br />

9.5.37 High level turbine construction activities and cranes would be visible on or below the horizon<br />

within a dip in the landscape at the head of the Carron Valley. The activities would <strong>for</strong>m very<br />

minor elements in distant views. Walkers are receptors of high sensitivity and would<br />

experience a negligible magnitude of change in view which would result in a Negligible<br />

significance of effect.<br />

farm would be visible adjacent to the more visually prominent Earlsburn wind farm. The<br />

proposals would <strong>for</strong>m a minor temporary element in distant views. Walkers in this location<br />

would be of high sensitivity to a change in view which would be of negligible magnitude,<br />

resulting in a Negligible significance of effect.<br />

Negligible non-significant effect.<br />

Viewpoint 22. Meikle Bin<br />

9.5.40 The peak of Meikle Bin provides a local high point in the landscape <strong>for</strong> panoramic views over<br />

the study area. The <strong>for</strong>estry covered slopes of the Carron Valley, rising up from the curving<br />

expanse of the reservoir dominate the view. The wind farms at Earlsburn and Craigengelt are<br />

prominent features in the adjoining moorland plateau. The construction site and activities at<br />

the proposed wind farm would <strong>for</strong>m a prominent addition to the rounded profile of Cairnoch<br />

Hill, visible below the ridge of the plateau beyond. The felling of trees to accommodate the<br />

turbines and access tracks would be visible from this elevated location however, this would<br />

be similar to practices typical of the ongoing management of the commercial <strong>for</strong>est. The<br />

construction phase of the proposed wind farm would <strong>for</strong>m a visually prominent and slightly<br />

discordant aspect of the view in the short term. Receptors in this location would be of high<br />

sensitivity and the magnitude of change would be medium temporarily resulting in a Moderate<br />

and non-significant effect.<br />

Operation<br />

Activities Associated with the Operational Phase<br />

9.5.41 The operational phase of the wind farm <strong>for</strong> the purposes of this assessment is considered to<br />

last <strong>for</strong> a period of twenty-five years. The following structures have been considered;<br />

• Wind turbines;<br />

• Anemometry Mast;<br />

• Sub station/control building;<br />

• Access tracks;<br />

• Movement of wind turbine blades;<br />

• Aviation warning lights.<br />

9.5.42 In line with a requirement <strong>for</strong> aviation lighting stipulated by Defence Estates (see Chapter 2:<br />

The Environmental Impact Assessment and Scoping Process, Table 2.1), the turbines will be<br />

fitted with an appropriate <strong>for</strong>m of lighting which is proposed to be infrared, subject to<br />

agreement with Defence Estates and other relevant consultees. As the <strong>for</strong>m of lighting is still<br />

to be agreed, visible lighting has been used <strong>for</strong> the purposes of this assessment to present a<br />

worst case scenario. However, if infrared lighting is adopted, which is not visible to the human<br />

eye at distances of more than 500m, the proposals would not result in any change to<br />

predicted effects on visual receptors or landscape character.<br />

9.5.43 The visual effects of the movement of the blades will vary according to wind direction,<br />

meteorological conditions and distance. The paragraphs below have taken into account the<br />

effects of blade movement on the views available to visual receptors.<br />

Effects on Landscape Resources During the Operation of the Wind Farm<br />

Methodology<br />

9.5.44 The detailed methodology used in assessing the significance of effects has been undertaken<br />

using the methodology set out in Section 9.2 and is the same as that used in assessing the<br />

construction effects. The value of the landscape resource (based on designations) and its<br />

Carron Valley Wind Farm<br />

sensitivity to the proposed development is considered in relation to the magnitude of the<br />

proposed change. The importance of the change to the landscape resource can then be<br />

assessed. Unlike the temporary nature of the construction phase, the effects of the<br />

operational phase are considered (<strong>for</strong> the purposes of this assessment) to be permanent.<br />

Consideration has been given as to whether the wind farm would be the key landscape<br />

characteristic, that is whether the wind farm would establish a ‘wind farm landscape type’ and<br />

further from the site, a ‘wind farm landscape sub-type’ or whether it is a landscape element<br />

within another landscape type or sub-type. The effects on the landscape fabric and character<br />

during the operation of the wind farm are set out in detail at Appendix 9.8.<br />

Effects on Designated landscapes<br />

Loch Lomond and the Trossachs National Park<br />

9.5.45 The special qualities of the National Park are defined at para. 9.3.11 to 9.3.13 and generally<br />

focus on physical attributes of the landscape within the park boundaries. The special qualities<br />

defined by the LLTNPA would not be unacceptably harmed by the introduction of the<br />

proposed wind farm into the landscape of the Carron Valley. In long distance views from the<br />

National Park the wind farm would at times be evident but often would be barely perceptible.<br />

The tranquillity of the park would there<strong>for</strong>e not be materially altered.<br />

9.5.46 Within the Loch Lomond and The Trossachs National Park Local Plan, Policy REN5<br />

Renewable Energy Development Adjacent to the National Park Boundary provides some<br />

guidance <strong>for</strong> development outside, although visible from, the National Park. The wind farm<br />

would be located at least 20 km from areas within the ZTV within the National Park boundary<br />

and would not be directly affected by the proposals. The distance helps to preserve a buffer<br />

between users of the LLTNP and the proposed wind farm. The turbines would be seen as a<br />

new very minor or barely discernible element associated with existing wind farms in the<br />

vicinity.<br />

9.5.47 Landscape character types which coincide with the National Park are illustrated on Figure<br />

9.9. An assessment of effects on their character can be found at paragraph 9.5.65 and in<br />

Appendix 9.8. With high sensitivity but negligible magnitude of effect, the significance of the<br />

operational effects of the proposed wind farm on the character of the National Park can be<br />

summarised as Slight adverse and not significant. The effects on visual receptors within the<br />

National Park located at viewpoints 18, 19, 20 and 21 would generally be Slight adverse also,<br />

and not significant (see paragraphs 9.5.104 to 9.5.111).<br />

Areas of Great Landscape Value<br />

9.5.48 These landscape designations define and protect small, local areas of scenic and<br />

recreational value. The proposal would lie within an AGLV which comprises the western end<br />

of the Campsie Fells and the plateau landscape of the Fintry, Gargunnock and Touch Hills.<br />

The wind farm would be located in an area of commercial <strong>for</strong>estry and would have a direct<br />

effect on the landscape fabric and character of the Carron Valley. The arrangement of the<br />

turbines would reflect the curving <strong>for</strong>m of the reservoir and would sit below the plateau<br />

landscape which lies to the north and <strong>for</strong>ms the majority of the AGLV. The proposed wind<br />

farm would <strong>for</strong>m a prominent addition to the landscape in the context of existing wind farms at<br />

Earlsburn and Craigengelt. The scenic value of the Carron Valley within the wider AGLV<br />

would be affected, however the recreational resource would be largely unaltered. Six<br />

viewpoints have been assessed which lie within the AGLV. Walkers at viewpoints within the<br />

base of the valley at Todholes Bridge (Viewpoint 1) and south of the reservoir (Viewpoint 6)<br />

would experience Substantial effects. Cyclists south of the reservoir (Viewpoint 6) would<br />

experience Major effects. Residential receptors east of the reservoir (Viewpoint 4) would<br />

experience Slight effects. On the edge of the plateau to the north (Viewpoints 2 and 3)<br />

walkers would experience Moderate effects and from Fintry to the west (Viewpoint 8)<br />

residential receptors would experience Negligible effects. Effects on character types which<br />

comprise the AGLV are generally of Moderate significance. The medium magnitude of<br />

change on a landscape of medium sensitivity would result in a Moderate significance of<br />

effect. Sufficient landscape would remain largely undeveloped within the AGLV to prevent the<br />

overall effects from becoming significant.<br />

National Scenic Areas<br />

9.5.49 The Loch Lomond NSA and the Trossachs NSA lie with the boundary of the National Park.<br />

These nationally designated landscapes share the same attributes as the National Park.<br />

Effects on the character and scenic qualities of these areas would be the same as discussed<br />

in paragraph 9.5.64 and paragraphs 9.5.104 to 9.5.111.<br />

Regional Scenic Areas<br />

9.5.50 There are three RSAs within the study area; the Kilpatrick Hills (within West Dunbartonshire),<br />

the Campsie Fells (within East Dunbartonshire) and the Kilsyth Hills (within North<br />

Lanarkshire). RSA’s are designated <strong>for</strong> the scenic quality of their landscape and are<br />

protected at a regional level. The RSA’s coincide with the Campsie Fells Upland Hills<br />

character type which lies in close proximity to the south of the proposed wind farm. The<br />

prominent proposed wind farm development in the context of the upland hills and existing<br />

wind farms at Earlsburn and Craigengelt in the neighbouring Fintry, Gargunnock, Touch Hills<br />

character type would result in an indirect effect on a landscape of medium sensitivity and<br />

medium magnitude of change which would be of Moderate significance.<br />

Landscape Character: Direct Effects<br />

9.5.51 The likely effects on the landscape fabric and character during the operational phase are<br />

described in tables at Appendix 9.8.<br />

9.5.52 The proposed wind farm would lie within the Upper Carron Lowland River Valleys Character<br />

Area. Figure 9.9 shows the application boundary overlapping with the adjoining Fintry,<br />

Gargunnock and Touch Lowland Hills character area. However, the SNH based character<br />

boundaries do not entirely reflect the genuine landcover and topography in this location. The<br />

site lies within an area of commercial <strong>for</strong>estry on Cairnoch Hill which extends further north<br />

than the SNH boundary suggests. The assessment considers the Upper Carron Valley to be<br />

the host character area with consideration also of the indirect visual effect on the adjacent<br />

character of the Fintry, Gargunnock and Touch Lowland Hills. The Lowland Hills to the north<br />

comprise open moorland and <strong>for</strong>m the plateau edge of this character area.<br />

9.5.53 Direct effects on the Upper Carron Lowland River Valleys character area would include the<br />

introduction of a new landscape feature into the area. There are no operational windfarms<br />

within the valley landscape and the proposed wind farm would <strong>for</strong>m a prominent new<br />

addition. The relatively enclosed nature of the valley, comprising dense commercial <strong>for</strong>estry<br />

covering the valley sides which rise up from the curving expanse of water <strong>for</strong>med by the<br />

reservoir, creates a sense of containment and partial separation from the wider landscape.<br />

Areas of conifer plantation would be felled to accommodate the turbines and wind farm<br />

infrastructure. The necessary work to the woodland would be incorporated into the ongoing<br />

Forest Management Plan and would be typical of practices within a commercially managed<br />

<strong>for</strong>est. The commercial <strong>for</strong>estry, as a feature of the landscape character area, is of medium<br />

sensitivity to a medium magnitude of change. The effect on the character of the <strong>for</strong>estry land,<br />

as a result of the wind farm would be Moderate and not significant.<br />

9.5.54 The turbines would be arranged around the sides of Cairnoch Hill to reflect the underlying<br />

topography of the site. Open views would be retained to the summit of the hill. The turbines<br />

would also reflect the curving <strong>for</strong>m of the reservoir and the dominant pattern of this valley<br />

landscape. The creation of the reservoir and the extensive area of commercial <strong>for</strong>estry have<br />

eliminated any sense of wild character within the valley. The condition of the character area is<br />

good and the value, based on the regional importance of the AGLV, is medium. The<br />

sensitivity would be medium and the magnitude of change also medium, resulting in a<br />

Moderate and non-significant effect.<br />

9.5.55 The proposed wind farm although prominent, would not be of sufficient scale to result in the<br />

creation of a wind farm landscape character sub type within the Upper Carron Lowland River<br />

Valley.<br />

9.5.56 The nighttime effect of aviation warning lights on proposed turbines in a relatively dark rural<br />

landscape would be Slight adverse within the character type. The presence of lights on<br />

turbines at the Earlsburn and Craigengelt Wind Farms has established a similar context<br />

immediately adjacent to the proposal site.<br />

Landscape Character: Indirect Effects<br />

9.5.57 The Fintry, Gargunnock and Touch Lowland Hills character area lies immediately to the north<br />

of the Upper Carron Valley and provides important landscape context to the proposal. The<br />

range of hills <strong>for</strong>m an upland plateau with steep scarp slopes to the north and west. The land<br />

cover of open moorland contrasts with the <strong>for</strong>ested Carron Valley. The presence of existing<br />

wind farms at Earlsburn and Craigengelt <strong>for</strong>m prominent established features in the<br />

landscape which lie in close proximity to the proposal site and the southern edge of the<br />

character area.<br />

9.5.58 The proposed wind farm would <strong>for</strong>m a prominent new feature in the context of this landscape<br />

character area which would have an influence over the landscape character. Wind turbines<br />

currently <strong>for</strong>m an important feature within this character area. The proposed development<br />

would <strong>for</strong>m an intensification of this character through the close proximity of the development<br />

and the relationship between the three schemes. The sensitivity of the character area would<br />

be medium and the magnitude of change medium, resulting in a Moderate non-significant<br />

effect.<br />

9.5.59 Nighttime effects of warning lights on turbines in the context of existing turbine lighting within<br />

the character type would be Slight and not significant.<br />

9.5.60 The Campsie Fells Upland Hills and Campsie Fells Lowland Hills character areas lie adjacent<br />

to the Carron Valley to the south. The ridge of hills <strong>for</strong>m the backdrop to the proposal site and<br />

the northern edges of the character type <strong>for</strong>m the upper reaches of the Carron Valley sides.<br />

The commercial <strong>for</strong>estry of the reservoir fringes have a similar character to the proposal site<br />

however the open moorland of the ridge top provides contrast. The upper reaches of the hills<br />

<strong>for</strong>m an elevated vantage point <strong>for</strong> panoramic views over the study area. The proposed wind<br />

farm would provide an intensification of developments in the context of the character areas,<br />

having an influence over their sense of remoteness. The sensitivity of the landscape and the<br />

magnitude of change would be medium leading to a Moderate significance of effect during<br />

the day and a Slight effect at night, which are not significant.<br />

9.5.61 The Middle Endrick Water Lowland River Valleys character area lies to the west of the Carron<br />

Valley. The proposed turbines would be visible from relatively large parts of the lowland<br />

farmed landscape. The proposed wind farm would <strong>for</strong>m a new type of development visible in<br />

the context of a rural landscape with no existing visual relationship with windfarms in the<br />

vicinity. The sensitivity of the landscape and the magnitude of change would be medium,<br />

resulting in a Moderate significance of effect in the daytime and Slight effect at night, which<br />

are not significant.<br />

9.5.62 The Middle Carron Lowland River Valleys character area and the Denny Muir Lowland Hill<br />

Fringes character area lie adjacent to the proposed wind farm site to the east. These<br />

landscapes <strong>for</strong>m a strongly contained corridor of farmland, moor and woodland. Limited<br />

intervisibility with the proposed wind farm would result in a medium sensitivity and a small<br />

magnitude of change in character. The effects would be Slight during the day and Negligible<br />

at night, which are not significant.<br />

9.5.63 Other character areas within the Lowland, Coastal and Upland character types within 5 km to<br />

35 km of the proposal site are located mainly to the east of the site between the Ochil Hills in<br />

the north and the West Lothian Plateau in the south. The location of intervening land<strong>for</strong>m<br />

within the Touch Hills and Kilsyth Hills, and the intensely developed swathe of land<br />

associated with The River Forth, limits the intervisibilty between the character areas and the<br />

proposed wind farm. The presence of blade tips on a distant horizon in the vicinity of existing<br />

turbines would not have a significant influence over the character of landscape types within<br />

the study area. The sensitivity of these landscapes is generally medium or negligible and the<br />

magnitude of change would be small to negligible, resulting in a significance of effect ranging<br />

from Slight to Not significant during the day and Negligible to Not significant at night.<br />

9.5.64 Landscape character areas within the Highland character type are located within the Loch<br />

Lomond and the Trossachs National Park. There landscapes are located between 20 km to<br />

35 km from the study area and are of a very good condition and national value. However, the<br />

long distances and sense of separation between the proposals and the character areas<br />

would limit the influence the proposals would have over these landscapes. As a result these<br />

landscapes of high sensitivity, would experience a small magnitude of change and a Slight<br />

significance of effect during the day, reducing to Negligible at night, which are not significant.<br />

edge of the proposed wind farm may be possible, seen in the context of existing turbines at<br />

the Earlsburn Wind Farm. The magnitude of change in view would be negligible, resulting in a<br />

Negligible effect in the day and at night, which are not significant. Todholes Farm north of<br />

Randie<strong>for</strong>d Bridge approximately 300 m west of the site (approximately 1.2 km from the<br />

nearest proposed turbine (Turbine 5)) lies within open grassland, allowing occupiers of the<br />

property to gain views out over the river and woodland to the wind farm located on Cairnoch<br />

Hill. The turbines and anemometry mast would be prominent in the landscape and visible<br />

beside the Earlsburn Wind Farm to the north. The magnitude of the permanent operational<br />

effect would be large leading to a Substantial effect in the day, which is significant in terms of<br />

the EIA Regulations, and a Moderate effect at night.<br />

9.5.68 Five pairs of semi detached bungalows and houses on the B818 at Craigannet approximately<br />

1.3 km east of the site (approximately 1.4 km from the nearest proposed turbine (Turbine 15))<br />

are located at the base of the hill. Views of the turbines are restricted by the land<strong>for</strong>m to a<br />

couple of blade tips. The magnitude of change in view would be negligible, resulting in a<br />

Slight significance of effect during the daytime and a Negligible effect at night, which are not<br />

significant. Occupiers of Craigannet and Easterton Farms at the base of Craigannet Hill<br />

approximately 1.4 km and 1.7 km respectively east of the site (approximately 1.5 km and<br />

1.8 km respectively from the nearest proposed turbine (Turbine 15)) would experience similar<br />

effects to the nearby bungalows. Six properties on the B818 at Muirmill approximately 2.1 km<br />

east of the site (approximately 2.2 km from the nearest proposed turbine (Turbine 15)) are<br />

surrounded by scattered mature trees. Views of turbines on the eastern edge of the site<br />

would be heavily filtered by intervening trees, limiting the magnitude of effect to negligible and<br />

the significance of effect to Negligible in the day and Not significant at night, which are nonsignificant.<br />

Drum Farm at the base of Dundaff Hill approximately 1.7 km to the east of the site<br />

(approximately 2.3 km from the nearest proposed turbine (Turbine 15)) would experience<br />

similar effects.<br />

9.5.69 2.2 km north east of the site lies Easter Cringate Cottage (approximately 2.6 km from the<br />

nearest proposed turbine (Turbine 2)). The open moorland location and relatively elevated<br />

aspect of the property would allow residents to gain open views over the landscape and<br />

conifer plantations of turbines and anemometry mast rising up behind Cairnoch Hill. Views<br />

would be gained in the context of exiting wind farms at Earlsburn and Craigengelt. The<br />

magnitude of change of the permanent operational effect would be medium and the<br />

significance of effect would be Major during the day, which is significant in terms of the EIA<br />

Regulations and Moderate at night. Single storey properties at Easter Cringate and Cairnoch<br />

Lodge lie 300 m and 250 m north, respectively of the site (approximately 1.1 km and 1 km<br />

respectively from the nearest proposed turbine (Turbine 3)). These properties are located<br />

within groups of mature trees immediately north of the conifer plantation of the site.<br />

Occupiers of these properties would have filtered views through trees of turbines and<br />

anemometry mast rising out of <strong>for</strong>estry on Cairnoch Hill. The magnitude of change would be<br />

small and the significance of effect would be Slight in the day and Negligible at night, which<br />

are not significant. Cringate lies beside the Endrich Water valley approximately 500 m north<br />

of the site (approximately 800 m from the nearest proposed turbine (Turbine 1)). The<br />

land<strong>for</strong>m channels views immediately south. Turbines on the north western edge of the wind<br />

farm and the anemometry mast would be visible with a backdrop of the reservoir, <strong>for</strong>estry<br />

beyond and Meikle Bin. The magnitude of change would be medium resulting in a Major<br />

effect during the day, which is significant in terms of the EIA Regulations, and a Moderate<br />

effect at night. Further up the valley at the base of Ling Hill lies Burnfoot, approximately<br />

Carron Valley Wind Farm<br />

1.8 km to the north of the site (approximately 2.2 km from the nearest proposed turbine<br />

(Turbine 1)). This property lies within moorland which covers the valley sides of the burn.<br />

Views would be channelled towards the wind farm beyond a <strong>for</strong>eground of turbines at<br />

Earlsburn. The Carron Valley turbines and the anemometry mast would be visible as<br />

prominent additions to the view, with a backdrop of the reservoir and <strong>for</strong>estry beyond in the<br />

context of existing turbines at Earlsburn wind farm. The magnitude of change would be<br />

medium resulting in a Moderate significance of effect during the daytime and a Slight effect at<br />

night, which are not significant. The effect is not significant due to the presence of existing<br />

turbines at Earlsburn defining the expectations of the viewer at this location.<br />

Core Paths, Access Land and Public Viewpoints<br />

9.5.70 The <strong>for</strong>est track nearest to the southern shore of the Carron Valley Reservoir provides some<br />

opportunities <strong>for</strong> views towards the proposal site <strong>for</strong> walkers, cyclists and occupiers of<br />

vehicles. In several locations around the base of Haugh Hill near, framed views<br />

(approximately 600 m) between dense stands of conifers and over the scrubby edge of the<br />

reservoir would be gained towards the proposed wind farm. The turbines would <strong>for</strong>m<br />

prominent new elements in views which contain existing turbines at Earlsburn and<br />

Craigengelt. Wind farm infrastructure would also be visible. The magnitude of the permanent<br />

operational change would be large leading to Substantial effects <strong>for</strong> high sensitivity walkers,<br />

and Major effects <strong>for</strong> medium sensitivity cyclists and occupiers of vehicles, which are<br />

significant in terms of the EIA Regulations.<br />

Dynamic Views<br />

9.5.71 The B818 follows the southern boundary of the proposal site, adjacent to the northern shore<br />

of the reservoir. The sequential effects on occupiers of vehicles using this route are<br />

discussed in more detail at paragraphs 9.5.114 to 9.5.123.<br />

Viewpoint Analysis<br />

Viewpoint 1. Todholes Bridge<br />

9.5.72 This near view would contain a new focus following the development of the wind farm. The<br />

majority of the 15 turbine scheme would be visible on the slopes of Cairnoch Hill. The<br />

turbines would be seen as prominent new elements on the skyline, rising out of the blocks of<br />

conifer plantation. The turbines are evenly spaced within the view and would not unduly<br />

obstruct views of the landscape. The blocks and strips of trees which would need to be felled<br />

to accommodate turbines and access tracks are barely perceptible in this view due to the<br />

extensive area of retained <strong>for</strong>estry. The sensitivity of walkers at this location is high and the<br />

magnitude of change in view they would experience would be large. The nature of the<br />

permanent operational change would result in a Substantial effect, which is significant in<br />

terms of the EIA Regulations.<br />

9.5.73 Warning lights on turbines would be visible above the horizon in an essentially dark, unlit<br />

landscape. Effects on receptors would be Moderate, which is non-significant .<br />

Viewpoint 2. Cringate Law<br />

9.5.74 From this location on rising land to the north of the proposed site the turbines at the Earlsburn<br />

Wind Farm would dominate the view. The addition of 12 visible turbines and the anemometry<br />

mast of the proposed wind farm into the view would provide a secondary focus <strong>for</strong> walkers in<br />

this location. The turbines would be clustered around the western side of Cairnoch Hill beside<br />

the reservoir, in the valley landscape of the River Carron, currently dominated by conifer<br />

plantations. The blade tips of some of the turbines would break the horizon <strong>for</strong>med by the<br />

Kilsyth Hills. The open blocks and strips within the plantation created by the felling of <strong>for</strong>estry<br />

trees to accommodate turbine and access tracks would be visible, although not<br />

uncharacteristic in the managed landscape. The sensitivity of receptors would be high and<br />

the magnitude of change as a result of the introduction of further turbines into the view would<br />

be medium. The receptors expectation in this location is that turbines will be seen within the<br />

view. The addition of the proposals into the view would result in a Moderate effect, which is<br />

not significant.<br />

9.5.75 Warning lights on proposed turbines would be visible in the context of existing lighting on<br />

turbines within the Earlsburn Wind Farm. The landscape context is otherwise generally dark.<br />

Effects on receptors would be Slight which is not significant.<br />

Viewpoint 3. Minor Road near Earls Hill<br />

9.5.76 The 12 visible turbines and the anemometry mast of the Carron Valley Wind Farm would be<br />

seen beyond the brow of Cairnoch Hill which <strong>for</strong>ms an undulating land<strong>for</strong>m in the middle<br />

distance. The landscape of geometric blocks of commercial <strong>for</strong>estry, out of which the turbines<br />

would rise, contrasts with the open moorland of the <strong>for</strong>eground in which the wind farm at<br />

Earlsburn is located, visible on the right side of the view. The turbines and the anemometry<br />

mast are visible on the skyline against a distant backdrop of the Campsie Fells. The turbines<br />

would become a prominent addition to the view, although would not <strong>for</strong>m the dominant<br />

element. Other wind farm infrastructure would not be visible. The sensitivity of occupiers of<br />

vehicles would be medium and the sensitivity of walkers would be high. The magnitude of<br />

change would be small <strong>for</strong> both receptor groups leading to a Moderate effect <strong>for</strong> walkers and<br />

a Slight effect <strong>for</strong> occupiers of vehicles, neither of which would be significant. Effects on<br />

views gained by walkers in this location would not be Major as the wind farm would not<br />

dominate the view and the expectation of the viewer has been defined by the presence of the<br />

existing wind farm at Earlsburn.<br />

9.5.77 Lighting on proposed turbines would be visible in the context of existing lighting on turbines<br />

within the Earlsburn Wind Farm. The landscape setting is otherwise unlit. Effects on<br />

receptors would be Slight or Negligible, which is not significant.<br />

Viewpoint 4. Carron Valley Reservoir east<br />

9.5.78 The blade tips of two turbines on the eastern edge of the proposed wind farm would be<br />

visible on the skyline above the rising land<strong>for</strong>m and woodland of Craigannet Hill. The wind<br />

farm would not be immediately apparent to receptors at the eastern end of the reservoir.<br />

Occupiers of properties and walkers would be of high sensitivity, although the negligible<br />

magnitude of change would result in Slight effects on views, which are not significant.<br />

9.5.79 No lighting associated with the proposed wind farm would be visible. Existing street lights and<br />

lighting from within properties would <strong>for</strong>m the focus of nighttime views.<br />

Viewpoint 5. Tomtain Hill<br />

9.5.80 The elevated nature of the summit of Tomtain Hill provides opportunities <strong>for</strong> open views over<br />

Carron Valley to the mountains of the Loch Lomond and the Trossachs National Park on the<br />

distant horizon. The proposed wind farm would be visible on the side of Cairnoch Hill which<br />

sweeps down to the shore of the reservoir. The turbines and the anemometry mast would be<br />

visible within the mosaic of conifer plantations, felled trees and moorland of the <strong>for</strong>estry<br />

commission land. The proposed wind farm would <strong>for</strong>m a prominent addition to this valley<br />

which sits low in the landscape and would retain open views to the peaks within the national<br />

park. The wind farms at Earlsburn and Craigengelt occupy open moorland in the adjoining<br />

landscape area, providing an established context in which the proposed wind farm would be<br />

seen and defining the expectation of the viewer. The sensitivity of receptors in this location is<br />

high and the magnitude of change would be medium resulting in a Moderate effect. Effects<br />

are not significant due to the presence of existing wind farms in the view providing an<br />

established visual context within which the effects of the Carron Valley Wind Farm have been<br />

assessed.<br />

9.5.81 Lighting on proposed turbines would be visible in the context of existing lighting on turbines<br />

within the Earlsburn and Craigengelt wind farms and the telecommunication masts at Earl’s<br />

Hill. The only other significant light source would be vehicles on the B818 which follows the<br />

edge of the reservoir. The landscape setting is otherwise unlit. Effects on receptors would be<br />

Slight and not significant.<br />

Viewpoint 6. Carron Valley Reservoir south<br />

9.5.82 Open views across the reservoir would focus on the prominent new turbines with the<br />

proposed wind farm. Turbines at the Earlsburn and Craigengelt wind farms are visible on the<br />

skyline however, they are more distant and <strong>for</strong>m minor elements of the view. The proposed<br />

turbines would be located on the slopes of Cairnoch Hill in the contrasting landscape of<br />

dense blocks of conifer plantation and open <strong>for</strong>estry land. The strong shapes and <strong>for</strong>m of the<br />

managed landscape and the turbines would provide balance within the view. However, the<br />

proposed wind farm would <strong>for</strong>m the most prominent element in the view, visible against the<br />

undulating skyline. Walkers would be of high sensitivity to the large magnitude of change in<br />

view leading to a Substantial effect, which is significant in terms of the EIA Regulations. The<br />

ability to see all turbines and some other infrastructure including tracks and the felled areas of<br />

trees in relatively close proximity would result in the Substantial effects <strong>for</strong> receptors at this<br />

viewpoint. Cyclists would be of medium sensitivity and would experience a Moderate effect,<br />

which is not significant.<br />

9.5.83 Lighting on proposed turbines would be visible in the context of existing lighting on turbines<br />

within the Earlsburn and Craigengelt Wind Farms. The only other significant light source<br />

would be vehicles on the B818 beyond the reservoir. The landscape setting is otherwise unlit.<br />

Effects on walkers would be Moderate and cyclists would be Slight and not significant.<br />

Viewpoint 7. B822<br />

9.5.84 All 15 turbines in the proposed scheme would be visible on the slopes of Cairnoch Hill. The<br />

slender nature of the anemometry mast would begin to diminish the visibility of this element<br />

of the wind farm at this distance. The proposed wind farm would <strong>for</strong>m a significance increase<br />

in the extent of turbines within the view. The proposals would <strong>for</strong>m a continuation of the chain<br />

of turbines at Earlsburn Wind Farm, dropping down to the valley side of the River Carron.<br />

Areas of trees felled to accommodate the turbines would <strong>for</strong>m very minor changes to the<br />

broad blocks of conifers. The location of the proposed wind farm relates to the wider area of<br />

<strong>for</strong>estry spanning the entire view, in front of the moorland plateau beyond. The proposed<br />

wind farm would <strong>for</strong>m a prominent new element in a view which contains an existing wind<br />

farm of similar scale. The sensitivity of occupiers of vehicles using the B822 would be<br />

medium and the magnitude of change in view would also be medium, leading to a Moderate<br />

effect, which is not significant.<br />

9.5.85 Existing lighting on turbines within the Earlsburn Wind Farm and masts at Earl’s Hill would<br />

<strong>for</strong>m a nighttime context <strong>for</strong> views of the proposed wind farm turbines. The only other light<br />

source would be at Watershead farmstead. The landscape setting is otherwise unlit. Effects<br />

on receptors would be Slight and non-significant.<br />

Viewpoint 8. Fintry<br />

9.5.86 The proposed wind farm would be visible at the head of the Carron Valley where interlocking<br />

land<strong>for</strong>ms dip down to <strong>for</strong>m a shallow ‘V’ shape on the horizon. Only 3 turbines would be<br />

seen above conifer plantations and woodland fringes in the valley base. The turbines would<br />

be visible on the horizon as minor elements in the view. The farmland, moorland and <strong>for</strong>estry<br />

which comprise the view would remain the dominant elements. Occupiers of properties on<br />

the eastern edge of the village are receptors of high sensitivity. The small magnitude of<br />

change would result in a Slight effect which is not significant.<br />

9.5.87 Lighting within properties on the edge of Fintry and along the B818 would <strong>for</strong>m minor<br />

nighttime sources of light. Vehicles using the B818 would be more prominent. These limited<br />

light sources would <strong>for</strong>m the context <strong>for</strong> views of the warning lights on turbines, which would<br />

<strong>for</strong>m a minor addition to the view. The significance of the effect would be Negligible, which is<br />

not significant.<br />

Viewpoint 9. Earl’s Seat<br />

9.5.88 The majority of the proposed wind farm would be visible on the slopes of Cairnoch Hill in the<br />

mid distance view. The plateau landscape of the Fintry Hills frames the view to the left and<br />

provides a prominent location <strong>for</strong> the Earlsburn Wind Farm, visible on the skyline and against<br />

the Ochil Hills. The smooth slopes of the Campsie Fells and Meikle Bin flank the proposal to<br />

the right. The proposed wind farm would be visible below the horizon, in front of the<br />

Craigengelt Wind Farm. The proposed wind farm would <strong>for</strong>m a prominent, although minor<br />

addition to a view, within a landscape containing existing wind farms. The position would not<br />

coincide with the distinctive hill edge to the left. Walkers in this location would be receptors of<br />

high sensitivity, experiencing a small magnitude of change that would result in a Slight effect,<br />

which is not significant.<br />

9.5.89 Lighting on proposed turbines would be visible in the context of existing lighting on turbines<br />

within the Earlsburn and Craigengelt Wind Farms. Vehicles on a short stretch of the B818<br />

would be visible in the centre of the view. The landscape setting is otherwise unlit. Effects on<br />

receptors would be Slight and non-significant.<br />

Viewpoint 10. Balfron<br />

9.5.90 In this view near the edge of the settlement the proposed wind farm would be partially visible,<br />

filtered through the tree tops of an intervening woodland belt. The profile of the Carron Valley<br />

is apparent where the land<strong>for</strong>m dips down to reveal views of the proposal however, the<br />

turbines would be barley perceptible and the character of the predominantly rural view would<br />

be maintained. Receptors would be of high sensitivity and the magnitude of change would be<br />

negligible, leading to a Negligible non-significant effect.<br />

9.5.91 Warning lights on turbines would be barely perceptible beyond intervening woodland. Lighting<br />

within farm buildings may provide some context <strong>for</strong> nighttime views in a rural area. The effect<br />

would be Negligible, which is not significant.<br />

9.5.92 Following the preparation of wirelines during the design development process the wind farm<br />

has been successfully concealed beyond intervening hills in views from Stirling Castle and<br />

avoids conflicts with distinctive hill edges.<br />

Viewpoint 12. Wallace Monument<br />

9.5.93 The wireline reveals that the blade tips of two turbines would theoretically be visible from this<br />

location. It can be concluded that the barely perceptible nature of the proposals would not<br />

have a significant effect on views from the Wallace Monument. The existing wind farms at<br />

Craigengelt and Earlsburn would continue to <strong>for</strong>m the focus <strong>for</strong> views towards the horizon.<br />

The magnitude of change would be negligible, experienced by a high sensitivity receptor,<br />

resulting in a Negligible non-significant effect.<br />

9.5.94 The extensive, well lit urban areas within the river valley would provide the most significant<br />

light sources in this view. Warning lights on the proposed turbines would be visible on the<br />

horizon next to lights on the Craigengelt and Earlsburn turbines. These would be visible<br />

although relatively insignificant within the wider view. Effects on receptors would be<br />

Negligible and not significant.<br />

9.5.95 Views across the developed base of the broad <strong>for</strong>th valley towards the distant horizon of the<br />

Fintry/Gargunnock/Touch Hills and the Campsie Fells and Kilsyth Hills focus on the Earlsburn<br />

and Craigengelt Wind Farms which break the skyline. Some of the turbines within the<br />

proposed wind farm would be visible as barely perceptible additions to the view, overlapping<br />

with the Craigengelt Wind Farm, but below the horizon. The extensive development in the<br />

valley base and the massed hills of the plateau landscape would continue to <strong>for</strong>m the<br />

dominant elements of the view. The proposed wind farm would <strong>for</strong>m a very minor addition to<br />

the view in the vicinity of currently established wind farms and would not coincide with or alter<br />

the distinctive hill edge to the right. The high sensitivity of walkers and the negligible<br />

magnitude of change in this distant view would result in a Negligible effect which is not<br />

significant.<br />

9.5.96 Lighting within settlements within the river valley would provide the most significant light<br />

sources in this view. Warning lights on the proposed turbines would be visible on the horizon<br />

next to lights on the Craigengelt and Earlsburn turbines and masts at Earl’s Hill. These would<br />

be visible although relatively insignificant within the wider view. Effects on receptors would be<br />

Negligible and not significant.<br />

Viewpoint 14. Cowie<br />

9.5.97 The focus of this view is the large area of public open space (currently undergoing extensive<br />

remodelling) surrounding the receptor. The narrow sliver of undulating hills visible on the<br />

horizon <strong>for</strong>m a distant backdrop to the view. The Craigengelt Wind Farm <strong>for</strong>ms a distant<br />

focus <strong>for</strong> views of this plateau landscape, with Earlsburn Wind Farm less prominent to the<br />

right. The blade tips of 5 turbines at the proposed wind farm would <strong>for</strong>m a barely perceptible<br />

addition to the view beyond Craigengelt. Receptors in this location would be of high to<br />

medium sensitivity, experiencing a negligible magnitude of effect. The effect would be<br />

Negligible and not significant.<br />

9.5.104 This open view from the edge of the Loch Lomond and the Trossachs National Park extends<br />

over a middle distance of relatively flat farmland to a backdrop of hills. The head of the<br />

Carron Valley lies at the shallow notch on the horizon <strong>for</strong>med by the interlocking land<strong>for</strong>ms of<br />

the Fintry Hills and Campsie Fells. The location of the wind farm in this notch would avoid<br />

conflict with the more distinctive and sensitive hill edges on either side, there<strong>for</strong>e reducing<br />

any effect that it might have had on the perceived scale of this area of upland. The proposed<br />

wind farm would <strong>for</strong>m a distant, although recognisable new element in the view crossing the<br />

ridge of these hills. The edge of the Earlsburn Wind Farm is also visible on the horizon to the<br />

left of the view. The new development would <strong>for</strong>m a new focus within distant views however,<br />

the magnitude of change at this distance would be small. The high sensitivity receptors would<br />

experience a Slight effect, which is not significant.<br />

9.5.105 Scattered farmsteads and traffic on local roads are likely to <strong>for</strong>m the only nighttime light<br />

Earlsburn wind farm <strong>for</strong>m a nighttime context in which the warning lights on the proposed<br />

turbines at Carron Valley would be seen. The new distant light sources would result in a<br />

Negligible effect on views, which is not significant.<br />

Viewpoint 20. Ben Ledi<br />

9.5.108 Open views from this peak within the National Park comprise ranges of hills surrounding low<br />

lying, broad river valley bases. The cluster of turbines at the Carron Valley wind farm would<br />

be visible adjacent to the more visually prominent Earlsburn wind farm. The proposals would<br />

<strong>for</strong>m a slight intensification of development at this location beyond the Fintry Hills. The<br />

change in view would be barely perceptible at this distance. Walkers in this location would be<br />

of high sensitivity to a change in view which would be of negligible magnitude, resulting in a<br />

Negligible effect, which is not significant.<br />

9.5.109 Lighting at Callander and farmsteads and along roads would <strong>for</strong>m the main focus <strong>for</strong><br />

nighttime views in a dark rural landscape. Lighting on turbines would be seen as a minor<br />

addition to the view next to Earlsburn wind farm and in the wider context of lighting at the<br />

Braes of Doune scheme.<br />

Viewpoint 21. Conic Hill<br />

9.5.110 Views east from Conic Hill extend across undulating lowland farmland and moor. The series<br />

of hills <strong>for</strong>med by the Ochil Hills, Touch/Gargunnock/Fintry Hills and the Kilsyth Hills and the<br />

Kilsyth Hills and Campsie Fells dominate distant views and characterise the landscape. The<br />

majority of turbines within the proposed wind farm would be visible at the head of the valley<br />

which is defined by a gentle dip on the horizon. The location of the wind farm in this dip would<br />

avoid visual conflict with the distinctive hill edges, there<strong>for</strong>e reducing effects on the perceived<br />

scale of this area of upland. The proposal would <strong>for</strong>m a very distant, although recognisable<br />

feature within this view and would be more prominent than the Earlsburn Wind Farm, which is<br />

visible to the left. Walkers in this location are receptors of high sensitivity and they would<br />

experience a negligible magnitude of change in view and a Negligible effect which is not<br />

significant.<br />

9.5.111 Small rural settlements, scattered farmsteads, traffic on local roads and turbines at the<br />

Earlsburn wind farm <strong>for</strong>m a nighttime context in which the warning lights on the proposed<br />

turbines would be seen. The new distant light sources would result in a Negligible effect on<br />

views, which is not significant.<br />

Carron Valley Wind Farm<br />

Viewpoint 22. Meikle Bin<br />

9.5.112 The peak of Meikle Bin provides a local high point in the landscape <strong>for</strong> panoramic views over<br />

the study area. The <strong>for</strong>estry covered slopes of the Carron Valley, rising up from the curving<br />

expanse of the reservoir dominate the view. The wind farms at Earlsburn and Craigengelt are<br />

prominent features in the adjoining moorland plateau. The proposed wind farm would <strong>for</strong>m a<br />

prominent new development on the rounded profile of Cairnoch Hill, visible below the ridge of<br />

the plateau beyond. The areas of <strong>for</strong>estry felled to accommodate the turbines would be<br />

clearly visible from this elevated location however, in most situations this would appear to<br />

<strong>for</strong>m an extension of the ongoing management of the commercial <strong>for</strong>est. The access tracks<br />

are more typical of existing <strong>for</strong>estry tracks and do not appear uncharacteristic. The felled<br />

trees at Sir John de Graham’s Castle site open up the setting of this heritage feature on the<br />

edge of the reservoir. The changes to the conifer plantations generally provide an<br />

enhancement to the appearance of this large scale feature in the landscape and help to<br />

merge the site with the surrounding less managed parts of the landscape. The proposed wind<br />

farm would <strong>for</strong>m the most visually prominent wind farm in a view in which this type of<br />

development has been established. Receptors in this location would be of high sensitivity and<br />

the magnitude of change would be medium, resulting in a Moderate effect which is not<br />

significant. The presence of prominent existing wind farms defines the expectations of<br />

viewers at this location and prevents the visual effects of the proposals resulting in significant<br />

effects.<br />

9.5.113 Warning lights on the Earlsburn and Craigengelt turbines and masts at Earl’s Hill would <strong>for</strong>m<br />

an immediate nighttime context in which the proposed turbine lights would be seen. Vehicles<br />

on the B818 and more distant lighting in urban areas in the Forth valley would also be<br />

prominent in a largely dark, rural landscape. The effect on visual receptors would be Slight<br />

which is not significant.<br />

Sequential Effects<br />

Balfron to Carron Valley Reservoir travelling east on the B818<br />

9.5.114 Potential views of the proposed wind farm would be gained from a 17 km length of this road.<br />

Between Balfron and the western approach to the Carron Valley reservoir the road passes<br />

through an agricultural landscape of mainly pasture fields divided by hedgerows and blocks<br />

of mixed woodland. The land<strong>for</strong>m is gently undulating and the road is generally orientated<br />

directly towards the proposal site. Hedgerows lie along both sides of the road, channelling<br />

views ahead. In several locations more distant views towards the Fintry Hills and Campsie<br />

Fells are possible and the entrance to the Carron Valley between the two upland areas.<br />

Turbines on the western side of the wind farm would be partially visible on the horizon at the<br />

head of the Carron Valley (See viewpoint 8 Fintry). The proposals would <strong>for</strong>m a minor,<br />

although prominent addition to the view, often visible in the distance. Views would be<br />

intermittent and sometimes filtered by vegetation. The sensitivity of the receptor would be<br />

medium and the magnitude of effect would be small resulting in a Slight effect which is not<br />

significant.<br />

9.5.115 As the road approaches the western end of the reservoir views become relatively open. The<br />

turbines would be prominent on the <strong>for</strong>estry covered land<strong>for</strong>m of Cairnoch Hill (See viewpoint<br />

1 Todholes Bridge). As the road follows the shore of the reservoir turbines would only be<br />

visible where there are gaps in the intermittent fringe of native vegetation in front of dense<br />

blocks of plantation conifers. Views are generally directed across the reservoir to Meikle Bin.<br />

Views would be intermittent depending on the presence of vegetation. The sensitivity of the<br />

receptor would be medium and the magnitude of effect would be large resulting in Major<br />

effects which are significant.<br />

Carron Bridge to Todholes Bridge travelling west on the B818<br />

9.5.116 Potential views of the wind farm would be gained from an 8 km long section of this route.<br />

West of a small cluster of properties at Muirmill, as the trees thin out glimpses of turbine<br />

blade tips may be visible above Craigannet Hill. Approaching the eastern end of the reservoir<br />

the engineered damn wall is visible in the <strong>for</strong>eground and blade tips may be visible on the<br />

horizon (See viewpoint 4 Carron Valley Reservoir). The proposals would <strong>for</strong>m a barely<br />

discernible and easily missed element in the view. The sensitivity of occupiers of vehicles<br />

would be medium and the magnitude of effect negligible. The effect would be Negligible<br />

which is not significant.<br />

9.5.117 As the road follows the shore of the reservoir glimpses of the turbines are revealed through<br />

gaps in the intermittent fringe of native vegetation and dense blocks of plantation conifers<br />

within the proposal site. Views are generally directed across the open expanse of water at the<br />

reservoir to the range of <strong>for</strong>estry clad hills beyond including the peak at Meikle Bin. In this<br />

location the magnitude of change would be large to medium leading to a Major to Moderate<br />

effect, which is significant.<br />

9.5.118 As the road continues north the open moorland of the Fintry Hills <strong>for</strong>ms a contrasting<br />

backdrop to views of the wooded Carron valley. The proposed turbines would be visible in the<br />

<strong>for</strong>eground with the Earlsburn Wind Farm in the background. The proposals would be<br />

prominent in the view and <strong>for</strong>m a new focus <strong>for</strong> occupiers of vehicles. The magnitude of<br />

change would be large, leading to a Major effect which is significant.<br />

The A81 travelling east from Aberfoyle to Stirling<br />

9.5.119 From a 1 km length of road occupiers of vehicles are able to gain distant oblique views<br />

approximately 20 km south west over farmland and <strong>for</strong>estry of the proposed wind farm<br />

<strong>for</strong>ming a very minor element on the horizon of the Campsie Fells. The magnitude of change<br />

would be small, leading to a Slight effect which is not significant.<br />

The A81 travelling north from Glasgow to Balfron Station<br />

9.5.120 The earthworks and vegetation associated with a disused railway which lies parallel to the<br />

road are sufficient to obscure views of the proposed wind farm.<br />

The A811 travelling east from Loch Lomond south of Drymen<br />

9.5.121 Approximately 4 km of this road between 25 km and 20 km from the proposed wind farm site<br />

would provide a potential location <strong>for</strong> views of the proposals. The proposed wind farm would<br />

be visible on the horizon above the tops of the Campsie Fells and Fintry Hills. Trees and<br />

woodland intermittently obscure these distant views. The proposed wind farm would <strong>for</strong>m a<br />

minor, easily missed element in the view, visible <strong>for</strong> a few seconds on each occasion. The<br />

magnitude of change and effect would be Negligible and not significant.<br />

The West Highland Way from Balmaha to Conic Hill<br />

9.5.122 Heading east from the summit on the descent a 1 km stretch of the footpath would allow<br />

users to gain open views approximately 25 km to the east. The landscape in the vicinity of<br />

Carron Valley would be visible in the distance beyond a <strong>for</strong>eground of hills and lowland<br />

farmland. The proposed wind farm would be visible on the horizon as a very minor although<br />

recognisable element in the view. The sensitivity of the receptor would be high and the<br />

magnitude would be Negligible, resulting in a Slight effect which is not significant. This route<br />

is represented by viewpoint 21 described at paragraphs 9.5.110 to 9.5.111.<br />

Rob Roy Way/Cycleway NCR7 travelling north from Drymen<br />

9.5.123 The proposed wind farm at Carron Valley is visible as a distant element, approximately 20 km<br />

away, in the view from approximately 1 km of the route as it approaches a high point at Bet a<br />

Charcal. The sensitivity of the receptor would be high and the magnitude would be negligible,<br />

resulting in a Slight effect which is not significant. This is represented by viewpoint 18<br />

described at paragraphs 9.5.104 to 9.5.105.<br />

Summary of Effects<br />

9.5.124 Occupiers of three of the 29 residential properties within approximately 2 km of the proposal<br />

site would experience significant adverse effects during the day. Occupiers of vehicles driving<br />

in either direction on one of the four routes assessed would experience significant adverse<br />

sequential effects during the day. There would be no significant effects on walkers or cyclists<br />

using the two pedestrian/cycle routes considered within the sequential assessment.<br />

Receptors at two of the viewpoints assessed within the study area would experience<br />

significant adverse effects during the day. No other visual receptors would experience<br />

significant night time effects on views. In addition, no significant adverse effects on landscape<br />

character would occur within the study area. Table 9.11 below identifies the seven receptors<br />

which would experience significant adverse effects.<br />

Carron Valley Wind Farm<br />

Analysis of the Carron Valley Wind Farm against the Stirling Landscape Sensitivity<br />

and Capacity Study <strong>for</strong> Wind Energy Development<br />

9.5.125 The site of the proposed wind farm falls within the ‘area of constraint’ identified by the<br />

capacity study by reason of four of its seven defined criteria.<br />

Landscape Scale<br />

9.5.126 Two key questions which need to be considered when assessing the potential effects of the<br />

proposed wind farm on landscape scale are;<br />

• Are the hills in the context of the site perceived as high, but are actually low?<br />

• Are the turbines seen against a backdrop of these hills?<br />

9.5.127 The proposed wind farm would not be visible against a hill edge adjacent to the flat<br />

landscape of the Forth Valley, which is considered by the study to be the most sensitive<br />

landscape scenario. The proposal would be located in the Carron Valley which is separated<br />

from the scarp edge by the extensive plateau <strong>for</strong>med by the Touch, Gargunnock and Fintry<br />

Hills. Cairnoch Hill. The turbines would be arranged around the base of Cairnoch Hill which<br />

rises to 400 m AOD (approximately 180 m high) and Meikle Bin rises to 570 m AOD<br />

(approximately 340 m high). These hills <strong>for</strong>m the immediate context of the turbines, which sit<br />

within the Carron Valley landscape, relatively confined physically and visually. They are<br />

sufficiently large scale to accommodate the scale of the proposed turbines. Cairnoch Hill and<br />

Meikle Bin would only <strong>for</strong>m a backdrop to views of the turbines when looking across the<br />

reservoir from one of these hills to the other, not from the wider landscape of the Touch,<br />

Gargunnock and Fintry Hills. The area of constraint <strong>for</strong> turbines over 110 m high extends over<br />

the whole of the study area, regardless of the differing scale of the diverse landscape and the<br />

juxtaposition of key features within the landscape.<br />

Impacts of Existing and Consented Windfarms<br />

9.5.128 Clustering of wind farms in upland landscapes which <strong>for</strong>m a backdrop to the Forth Valley and<br />

those with a relationship with the edge of the Loch Lomond and the Trossachs National Park<br />

are considered, by the study, to be most sensitive. The proposed wind farm would be located<br />

in close proximity to the existing Earlsburn and Craigengelt Wind Farms however, its location<br />

within the Carron Valley is at a sufficiently low level in the landscape to conceal all but the<br />

blade tips in most views from the Forth Valley towards the Touch Hills. The proposals would<br />

be located at least 20 km from the boundary of the National Park, <strong>for</strong>ming a very minor or<br />

barely perceptible feature in a distant landscape character area which is not immediately<br />

related to the park.<br />

Landscape Pattern<br />

9.5.129 The pattern of the landscape at the proposal site and within the immediate vicinity is defined<br />

by the main landuse of commercial <strong>for</strong>estry beside a reservoir. Blocks of conifers in relatively<br />

geometric shapes, interspersed with open ground and the large expanse of water <strong>for</strong>ming a<br />

simple curving shape with some irregular edges and the 2 straight engineered dams define<br />

the landscape of Carron Valley. The valley sides rise up to horizon lines of undulating hills.<br />

The landscape pattern is of moderate diversity and complexity with landscape elements<br />

distributed at a moderate scale. The landscape of Cairnoch Hill and the Carron Valley would<br />

be of an appropriate scale to accommodate the proposed wind farm without compromising<br />

the landscape pattern.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

Area Valued <strong>for</strong> Sense of Remoteness while being easily accessed from an Urban Centre<br />

9.5.130 Two key questions which need to be considered when assessing the potential effects of the<br />

proposed wind farm on landscape sensitivity are;<br />

• Would the turbines conflict with the man made and managed aspects of the<br />

landscape?<br />

• Would a receptor engaged in recreational activities be sensitive to change of this<br />

nature in a landscape which contains existing windfarms?<br />

9.5.131 The site’s proximity to the large urban areas at Glasgow to the south extending round to<br />

Stirling in the north east and the inward looking and sparsely settled nature of Carron Valley<br />

would place the proposed wind farm site within this sensitive category. However, the<br />

dominance of commercial <strong>for</strong>estry and the presence of the reservoir rein<strong>for</strong>ce the area’s<br />

managed and man made character. People engaged in active recreational pursuits are<br />

considered to be of medium sensitivity to a change of this nature. The presence of existing<br />

wind farms within this immediate landscape context defines receptors’ expectations. The<br />

intensification of wind farm development would not significantly affect visual amenity in this<br />

location.<br />

Effects on Landscape Resources and Visual Receptors at Decommissioning<br />

9.5.132 The anticipated effects on landscape and visual resources associated with the<br />

decommissioning phase are expected to be broadly similar to those identified <strong>for</strong> the<br />

construction phase.<br />

9.6 Mitigation and Enhancement Measures<br />

9.6.1 The scheme design and mitigation measures described in Chapter 4: Description of the<br />

Proposed Development and Section 9.4 Topic Specific Design Evolution of this chapter have<br />

been included as an integral part of the scheme so as to avoid, minimise and, where<br />

necessary, compensate <strong>for</strong> potential adverse effects. No further landscape mitigation would<br />

be proposed.<br />

9.7 Assessment of Residual Effects<br />

9.7.1 No further secondary mitigation measures are proposed to address the residual effects of the<br />

scheme on receptors.<br />

9.8 Assessment of Effects on Potential Future Receptors<br />

9.8.1 No future potential landscape or visual receptors have been identified which are likely to<br />

experience significant adverse effects as a result of the proposed wind farm.<br />

9.9 Cumulative Effects<br />

9.9.1 The preceding sections have addressed the landscape and visual impacts of the proposed<br />

wind farm within an existing baseline which contains operational wind farms, particularly the<br />

nearby schemes at Earlsburn and Craigengelt. Legislation requires EIA also to address the<br />

cumulative impacts of a proposal together with other developments under development or<br />

planned in the area. The Scottish Executive’s web based advice ‘Onshore wind turbines’<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

(Feb.2011) which replaces PAN 45 highlights the likelihood that cumulative impacts may<br />

result in an eventual limit to the extent of onshore wind development ‘In areas approaching<br />

their carrying capacity the assessment of cumulative effects is likely to become more<br />

pertinent in considering new wind turbines, either as stand alone groups or extensions to<br />

existing wind farms. In other cases, where proposals are being considered in more remote<br />

places, the thresholds of cumulative impact are likely to be lower, although there may be<br />

other planning considerations’. The guidance also states that ‘In assessing cumulative<br />

landscape and visual impacts, the scale and pattern of the turbines plus the tracks, power<br />

lines and ancillary development will be relevant considerations. It will also be necessary to<br />

consider the significance of the landscape and the views, proximity and inter-visibility and the<br />

sensitivity of visual receptors’.<br />

9.9.2 Cumulative effects of wind farms are considered where the presence of other wind farms in a<br />

given area (usually within 70 km radius) in combination with the proposed wind farm may<br />

have an effect on the perception of the landscapes character or on views gained by sensitive<br />

receptors.<br />

9.9.3 As with the assessment of landscape effects, cumulative landscape effects can either be<br />

directly on the physical fabric of the landscape, or indirectly on the character of the<br />

landscape.<br />

9.9.4 Cumulative effects on visual amenity can be experienced either from static viewpoints, where<br />

two or more developments can be seen from a single location or from a series of points along<br />

a route experienced during a journey. This can either be combined visibility where the<br />

developments are visible in a single 75º arc of view or successively where the observer<br />

needs to turn to experience a wider arc of view; or sequentially, where in the process of<br />

moving along a route, two or more proposals are visible.<br />

9.9.5 A comprehensive search has been undertaken to identify other wind farms which are<br />

operational, under construction, consented or proposed, through various means of<br />

consultation. As a result 94 other commercial wind farms within a 70 km radius of the<br />

proposed wind farm at the time of submission of this <strong>ES</strong> have been identified and reviewed<br />

(See Figure 9.15 and 9.16). The relevant wind farms, excluding those in scoping, which lie<br />

within 35 km of the proposed wind farm (Figure 9.15 and 9.17) have been assessed and<br />

include the following:<br />

9.9.6 The proposal would lie within the AGLV centred on the Fintry, Gargunnock and Touch Hills.<br />

Six further schemes which are either operational, approved or an application made would<br />

also lie within the AGLV. The existing Earlsburn and Craigengelt wind farms and the<br />

approved Earlsburn extension are located in areas of open plateau which <strong>for</strong>m prominent and<br />

distinct elements within the AGLV. In addition applications have been submitted <strong>for</strong> wind<br />

farms at Muirpark, which would also lie in a landscape of a similar character, whilst Rullie and<br />

Craigannet wind farms would lie within open grazed moorland/grassland locations in lower<br />

lying Carron Valley settings. These last four additional cumulative schemes would create a<br />

more prominent loose cluster of wind farms and a significantly more developed context into<br />

which the Carron Valley Wind Farm would be placed. The proposed Carron Valley Wind<br />

Farm would be located on the side of the Carron Valley below the main plateau landscape.<br />

The proposal would lie within the Upper Carron Lowland River Valleys character area within<br />

the AGLV which is different to Earlsburn and its extension, Craigengelt, Muirpark and Rullie<br />

however, it would be strongly visually associated with these cumulative schemes and<br />

Craigannet. The introduction of the Carron Valley Wind Farm into this landscape of medium<br />

sensitivity would result in a small magnitude of change. The additional cumulative effect on<br />

the landscape character of the AGLV would be Slight, which is not significant.<br />

9.9.7 Appendix 9.10 Identifies the generic landscape character types in which the cumulative wind<br />

farms lie. Only 6 of the 16 character types in the study area would contain at least one of the<br />

37 wind farms. These character types are as follows:<br />

• Lowland River Valleys – 5 wind farms, in addition to the proposed wind farm;<br />

• Lowland Plateaux – 13 wind farms;<br />

• Lowland Plains – 4 wind farms;<br />

• Lowland Hills – 11 wind farms;<br />

• Lowland Hill Fringes – 2 wind farms;<br />

• Upland Hills – 2 wind farms.<br />

9.9.8 The proposed wind farm would be located in the Lowland River Valleys character type. Five<br />

further schemes which have been approved or an application made would also lie within<br />

various different parts of this character type within the study area. No existing wind farms are<br />

operational within the Lowland River Valleys. The Craigannet Wind Farm would lie within the<br />

same Upper Carron Lowland River Valleys character area and has the greatest potential to<br />

result in cumulative effects. This wind farm would be located in an area of grassland and<br />

moorland which differs from the land use of commercial <strong>for</strong>estry of the proposed wind farm<br />

site. There would be no significant cumulative loss of landscape features. However, there<br />

would be a direct adverse cumulative effect on the character of the Upper Carron Lowland<br />

River Valleys character area. The two schemes would be well related to each other in terms<br />

of size and scale in the valley setting. The sensitivity of the character type is medium and the<br />

magnitude of change would be small. The additional cumulative effect on character following<br />

the development of the proposed wind farm would be Slight which is not significant.<br />

9.9.9 The ASDA depot, Feddal Farm and Forthbank cumulative schemes lie in different character<br />

areas within the Lowland River Valleys character type at some distance from the proposal<br />

site. The relatively small number of schemes and the difference in the specific land cover in<br />

the site locations would prevent significant direct cumulative effects on landscape arising <strong>for</strong><br />

these wind farms in combination with the proposed wind farm. The additional cumulative<br />

effect which would occur as a result of the proposed wind farm on the landscape character of<br />

the Lowland River Valleys area would be Negligible and non-significant.<br />

9.9.10 The remaining 27 cumulative schemes do not lie within the same character type as the<br />

proposed wind farm. There would be no direct cumulative effect on the landscapes of the<br />

Lowland Plateaux, Lowland Plains, Lowland Hills, Lowland Hill Fringes or Upland Hills<br />

character areas as a result of the development of the proposed wind farm.<br />

9.9.11 There is the potential <strong>for</strong> cumulative indirect effects on generic landscape characteristics and<br />

features which are common to more than one character area within the study area. The<br />

attributes of remoteness and wild character occur within all of the Highland and Upland<br />

character types and the Lowland Hills and Lowland Hill Fringes character types. The<br />

Carron Valley Wind Farm<br />

Lowland Hills and Denny Muir Lowland Hill Fringes <strong>for</strong>m the immediate upland character<br />

context of the proposal site. The open nature of the peaks and ridges within these areas<br />

allowing extensive views over the study area and the lack of settlements and limited<br />

development result in a sense of remoteness. The existing wind farms at Earlsburn and<br />

Craigengelt <strong>for</strong>m the most prominent developments in the vicinity of the proposal site and<br />

<strong>for</strong>m part of the landscape character baseline. The approved Earlsburn extension and the<br />

Muirpark, Craigannet and Rullie Wind Farms which have had applications submitted would<br />

significantly increase the extent of development in the area and reduce the sense of<br />

remoteness of this part of the landscape. The combination of the six cumulative wind farms<br />

would create a wind farm landscape sub-type which would flow over the three separate<br />

character types. The additional cumulative effect on the sense of remoteness of the upland<br />

landscapes in the vicinity of the site, following the development of the proposed Carron Valley<br />

Wind Farm would result in a small magnitude of change which would lead to a Slight effect<br />

which is not significant. The proposal would be added to an established cluster of wind farms<br />

which would be more extensive in nature than the Carron Valley scheme. The addition of the<br />

proposed wind farm would not represent a significant increase in the overall scale of the wind<br />

farm cluster.<br />

9.9.12 The existing wind farm at Braes of Doune is currently visible from the Loch Lomond and the<br />

Trossachs National Park as the closest and most prominent wind farm development and lies<br />

within the landscape setting of the National Park. Two further existing wind farms at<br />

Earlsburn and Burnfoot are visible from the park as minor distant elements in the landscape<br />

which are beyond the immediate landscape setting of the park. The addition of a further five<br />

cumulative schemes, including the consented Earlsburn extension and applications <strong>for</strong> two<br />

Burnfoot Hill extensions and Standingfauld, between the edge of the park and the vicinity of<br />

existing visible wind farms are likely to be visible. The sensitivity of the National Park is high<br />

and the magnitude of change following the addition of the Carron Valley scheme would be<br />

negligible, resulting in a Negligible cumulative significance of effect.<br />

9.9.13 The most significant overlap between the proposed wind farm ZTV and the ZTV’s of<br />

cumulative schemes occurs <strong>for</strong> these five schemes in close proximity to the proposal site.<br />

The cumulative ZTV is concentrated around the Campsie Fells, Kilsyth Hills and the Fintry,<br />

Gargunnock and Touch Hills in the immediate vicinity of the site. Views from public access<br />

land, core paths, properties and roads within these areas would include the Carron Valley<br />

Wind Farm as a relatively minor addition to a larger, existing cluster of wind farms. Small<br />

areas of the peaks and high land within the Loch Lomond and the Trossachs National Park<br />

are affected and large parts of the lowland plateau between Glasgow and Falkirk and the low<br />

lying Forth valley landscape.<br />

Rullie Wind Farm<br />

9.9.14 Limited high points within the Campsie Fells, Kilsyth Hills and the Fintry, Gargunnock and<br />

of the lowland plateau between Glasgow and Falkirk and the low lying Forth valley<br />

landscape.<br />

<strong>for</strong> the Calcarb factory and Glentaggart Wind Farms.<br />

9.9.25 The area of the landscape which lies within an overlap of the greatest number of ZTV’s are<br />

the upper reaches and peaks of the Campsie Fells and Kilsyth Hills. These hills <strong>for</strong>m a<br />

significant ridge in the landscape of the study area, separating landscapes to the north from<br />

the urban mass of the Glasgow conurbation to the south.<br />

Cumulative Viewpoint Analysis<br />

9.9.26 The existing wind farms at Earlsburn and Craigengelt lie in close proximity to the proposal<br />

site and are visible in the photographs and photomontages which have been prepared <strong>for</strong> the<br />

viewpoints within the assessment. This has enabled cumulative visual effects with existing<br />

schemes and the proposed wind farm to be illustrated.<br />

9.9.27 Cumulative visual effects have been assessed based on nine key viewpoints of the 20<br />

locations taken through the assessment stage (see Figures at 9.18). The cumulative wind<br />

Earlsburn extension would <strong>for</strong>m a prominent feature on the horizon on the edge of the<br />

Lowland Hills and Fintry Hills. The proposed wind farm would <strong>for</strong>m a development of similar<br />

prominence in the view, visible as a continuation of the turbines to the east. Approximately<br />

120º of the view would contain wind farm developments. The magnitude of change would be<br />

medium and the additional successive cumulative visual effect of the proposed wind farm<br />

would be Major which is significant.<br />

Viewpoint 2 Cringate Law<br />

9.9.29 The viewpoint at Cringate Law is located within the footprint of the existing Earlsburn Wind<br />

Farm. The turbines <strong>for</strong>m dominant elements in a 180º angle of the view between the south,<br />

east and north. The tips of the existing Craigengelt turbines are visible breaking the horizon<br />

to the south east. In addition the consented Earlsburn extension to the north and north west<br />

would also <strong>for</strong>m a significant element in the <strong>for</strong>eground and Craigannet in planning scheme<br />

would be beyond Earlsburn to the south east. Very distant existing schemes at<br />

Greendykeside, Black Law and extension and the consented Tormywheel would be<br />

potentially visible to the south east. Approximately 270º of the view would include prominent<br />

wind farms. The proposed wind farm would be located to the south beyond turbines at<br />

Earlsburn. The scheme would <strong>for</strong>m a prominent new element in the view which would be<br />

defined by cumulative wind farms. The magnitude of change would be small and the<br />

additional effect of the proposed wind farm would be Slight which is not significant.<br />

Viewpoint 3 Minor road near Earls Hill<br />

9.9.30 In this near view the existing Earlsburn Wind Farm is partially visible beyond land<strong>for</strong>m to the<br />

west and Craigengelt is very prominent in the <strong>for</strong>eground to the south. Schemes which are in<br />

planning include Craigannet which would be visible immediately south of Craigengelt and the<br />

tops of turbines at Muirpark which would be visible to the south east adjacent to Craigengelt.<br />

The wind farms would collectively occupy approximately 140º of the view. The proposed wind<br />

farm would be partially visible beyond Cairnoch Hill to the south west within a gap in the<br />

landscape between Craigannet and Earlsburn wind farms. Cumulatively approximately 180º<br />

of the view would contain wind farm developments. The magnitude of change would be small<br />

and the additional effect of the proposed wind farm would be Moderate which is not<br />

significant.<br />

Viewpoint 5 Tomtain Hill<br />

9.9.31 This elevated location on the Kilsyth Hills allows panoramic views to be gained over a diverse<br />

array of rural landscapes and urban townscapes in the study area. In the vicinity of the<br />

proposal site the existing Earlsburn and Craigengelt Wind Farms lie prominently in the middle<br />

distance on the edge of the Lowland Hills, whilst Braes of Doune lies in the distance beyond.<br />

The addition of the consented Earlsburn extension and planned Craigannet and Muirpark<br />

schemes would <strong>for</strong>m a cluster of wind farm developments extending over approximately 60º<br />

of the view to the north. The schemes would <strong>for</strong>m a wind farm landscape character sub-type.<br />

landscape on the fringes of Glasgow a cluster of seven wind farms including the existing<br />

Greendykeside, Black Lawand Greengairs, the consented Tormywheel and Hartwood which<br />

is in planning would be visible in the distance. Wind farms would be visible as prominent<br />

elements in approximately 180º of this view and would <strong>for</strong>m barely perceptible additions to<br />

the landscape in the remaining view. The proposed wind farm would <strong>for</strong>m the closest visible<br />

scheme predominantly to the left of Earlsburn, whilst retaining some degree of visual<br />

separation with this scheme and the Craigannet wind farm to the north. The proposed wind<br />

farm would <strong>for</strong>m an intensification of development is this cluster of wind farms on the edge of<br />

the Carron Valley Lowland River Valley and Fintry, Gargunnock and Touch Lowland Hills<br />

character types. The magnitude of change would be small and the additional effect of the<br />

Carron Valley proposal would be Slight which is not significant.<br />

Viewpoint 9 Earl’s Seat<br />

9.9.32 In views to the east from this peak within the Campsie Fells the existing Earlsburn and<br />

Craigengelt Wind Farms <strong>for</strong>m minor, although prominent developments on the horizon in the<br />

middle distance. The addition of the consented Earlsburn extension and the planned Muir<br />

Park, Craigannet and Rullie Wind Farms in the vicinity would create a more prominent cluster<br />

extending over approximately 30º of the view. The existing Braes of Doune Wind Farm is<br />

visible in the distance to the left of this cluster and a cluster of seven schemes including the<br />

existing Greendykeside, Black Lawand Greengairs wind farms, the consented Tormywheel<br />

scheme and Hartwood which is in planning would be visible in the distance to the south east<br />

beyond the urban fringes of Glasgow. The Carron Valley wind farm would be located in front<br />

of the Muir Park, Craigengelt, Craigannet and Rullie Wind Farms, on the valley side below<br />

the horizon. The proposal would not increase the horizontal extent of wind farms visible in<br />

this view. It would <strong>for</strong>m an intensification of development within this cluster resulting in a<br />

small magnitude of change and an additional cumulative effect which is Slight and not<br />

significant.<br />

Viewpoint 13 Dumyat Hill<br />

9.9.33 Views in the vicinity of the proposal site currently focus on the distant although prominent<br />

existing wind farms at Earlsburn and Craigengelt on the horizon of the Fintry, Gargunnock<br />

and Touch Hills. The consented Earlsburn extension and planned Craigannet and Muir Park<br />

schemes would expand this loose cluster to approximately 20º in this south westerly<br />

direction. The series of 14 distant schemes to the south including Tormywheel, Rosehill,<br />

Black Law and extension, Torwood, Hartwood, Glentaggert, Greendykeside, Greengairs,<br />

Blantyre Muir and extension and Rullie spread across approximately 50º of the view. There<br />

are no visible cumulative schemes to the north or east. The addition of the proposed wind<br />

farm to the cluster to the south west would <strong>for</strong>m a minor intensification of development in this<br />

part of the view. The magnitude of change would be negligible which would result in<br />

additional cumulative effects which are Negligible and non-significant.<br />

be the existing Black Law and Greendykeside schemes the consented Black Law extension<br />

and Greengairs and the planned Rullie and Hartwood wind farms. The existing Braes of<br />

addition of the planned Craigannet scheme would expand this distant cluster. The existing<br />

Braes of Doune scheme to the north east would <strong>for</strong>m the only other recognisable scheme in<br />

the view. Views to the north, south and west would not be affected by wind farm<br />

development. The proposed wind farm would be of a similar level of visibility to the Earlsburn<br />

9.9.36 This peak within the Campsie Fells, in relatively close proximity to the proposal site, allows<br />

panoramic views to be gained over a diverse study area of rural landscapes and urban<br />

townscapes. To the north the existing Earlsburn Wind Farm is prominent on the Fintry Hills in<br />

the middle distance. The existing Braes of Doune scheme is more distant, although still<br />

prominent in the landscape beyond. The existing Craigengelt Wind Farm is prominent in the<br />

Lowland Hills to the north east. With the addition of the consented Earlsburn extension and<br />

the planned Craigannet and Muir Park schemes two clusters would <strong>for</strong>m with a third group of<br />

turbines to the east at Rullie, which is in planning. These schemes, although not continuous<br />

across the horizontal extent of the view, would occupy a large proportion of this quadrant of<br />

the view between the north and east. Another more distant cluster of wind farms would be<br />

located to the south east including the existing Black Lawand Greendykeside, the consented<br />

Black Law extension, Tormywheeland Greengairs and the Hartwood scheme which is in<br />

planning. These schemes would <strong>for</strong>m minor or barely perceptible addition to the view. The<br />

proposed wind farm would <strong>for</strong>m the closest scheme to the viewer and would be located within<br />

the valley landscape in front of and visually overlapping with the Earlsburn, Craigengelt and<br />

Craigannet Wind Farms. The scheme would be prominent and would result in a significant<br />

intensification of development within the existing cluster and a medium magnitude of change.<br />

Additional cumulative effects due to the proposal would be Moderate which is not significant.<br />

9.9.37 The cumulative visual effects of the Carron Valley wind farm in combination with other<br />

schemes from viewpoints 4, 8, 10, 12, 14, 15, 16, 18 and 19 would be Negligible and not<br />

significant. The cumulative effects <strong>for</strong> viewpoints 6 and 7 are well presented in<br />

photomontages at Figures 9.14- 6b and c and 9.14 – 7b and c. The cumulative effects on<br />

9.9.44 The existing Earlsburn and Braes of Doune wind farms, consented Earlsburn extension, and<br />

the planned Craigannet wind farm would be visible from the majority of this section of the<br />

footpath. The consented Cathkin Braes scheme would also be visible from a large section of<br />

this route. The high sensitivity of walkers and the negligible magnitude of change as a result<br />

of the Carron Valley Wind Farm would lead to a Negligible additional effect, which is not<br />

significant.<br />

Landscape and Visual Impact Assessment


Carron Valley Wind Farm<br />

Cumulative Effects of Wind Farms 35 to 70 km from the Proposal Site<br />

9.9.45 Cumulative wind farms within a zone between 35 km and 70 km from the proposal site total<br />

56 schemes (See Figure 9.16). The majority of these schemes are located to the south of<br />

Glasgow in a swathe of landscape between the coast in Ayrshire, through Renfrewshire to<br />

the South Lanarkshire and the Pentland Hills. A second cluster of schemes would extend<br />

along the northern coast of the Firth of Forth within Fife. The ability to gain views of<br />

cumulative wind farms south of Glasgow, in combination with the Carron Valley scheme is<br />

limited by the lack of hills towards the southern edge of the 25 km radius study area, which<br />

might enable views to the north towards the proposals and south towards the cumulative<br />

wind farms. However, the Ochil Hills to the north east of the proposal site straddle the 35 km<br />

radius buffer, providing an elevated location <strong>for</strong> distant views south west towards the site and<br />

south east towards schemes within Fife. There is potential <strong>for</strong> successive cumulative effects<br />

on views from the Ochil Hills. The Carron Valley wind farm would <strong>for</strong>m a barely perceptible<br />

element in views from this location and its addition to the cumulative baseline would not result<br />

in significant effects.<br />

Summary of Cumulative Effects on Visual Receptors<br />

9.9.46 It is anticipated that the greatest number of potential views of cumulative wind farms<br />

schemes, whether in combination with the proposal, or successively if the receptor turns 360<br />

degrees, would be attained within the Campsie Fells and Kilsyth Hills. Cumulative visual<br />

effects have been assessed based on nine key viewpoints of the 20 locations taken through<br />

the assessment stage, of which only one would receive additional successive cumulative<br />

significant visual effects, at Todholes Bridge.<br />
