1 INTRODUCTION 

1.1 Assessment Requirements 

Helensburgh Coal Pty Ltd (HCPL) owns and operates the Metropolitan Colliery, located 

approximately 30 kilometres (km) north of Wollongong in New South Wales (NSW). The 

Metropolitan Colliery has a long history that extends back to the 1880s and longwall mining 

commenced at the Metropolitan Colliery in 1995. The mine currently produces approximately 

1.5 million tonnes (Mt) of coking coal per year. 

HCPL proposes an expansion of the Metropolitan Colliery raw coal production and upgrade of the 

Coal Handling and Preparation Plant (CHPP) to increase saleable coal production which is 

referred to as the Metropolitan Coal Project (the Project). Heggies Pty Ltd (Heggies) has been 

engaged by HCPL to evaluate and assess the potential noise impacts associated with the Project. 

The assessment has been guided by the NSW Department of Planning (DoP) Environmental 

Assessment Requirements (EARs) which require consideration of potential construction, 

operational and on-site and off-site road and rail noise and vibration impacts. 

In accordance with the DoP requirements, the major sources of noise emissions may be grouped 

as follows: 

On-site Intrusive Noise Assessment 

Surface construction works would be undertaken intermittently over a period of up to five years, 

generally during daytime hours. Construction activity associated with the CHPP upgrade and 

establishment of a backfill paste plant would coincide with the end of Year 3 operations and have 

been assessed cumulatively with other on-site operational noise sources. Project operations in 

Year 15 coincide with peak coal production and have also been assessed. 

The NSW Industrial Noise Policy (INP 2000) provides non-mandatory procedures for setting 

acceptable LAeq(15minute) intrusive (and LAeq(period)) amenity noise levels for various receiver areas 

and guidelines for assessing noise impacts from on-site stationary noise sources. 

Cumulative Industrial Noise Amenity 

The INP also provides non-mandatory cumulative noise assessment guidelines that address 

existing and successive industrial development by setting acceptable (and maximum) cumulative 

LAeq(period) amenity levels for all industrial (ie non-transport related) noise in a receiver area. Note, 

the INP does not set acceptable cumulative LAeq(15minute) intrusive criteria for all industrial noise 

sources in a receiver area, but rather seeks to control cumulative noise via its amenity criteria. 

The existing Metropolitan Colliery is the only significant industrial development located to the east 

of the Helensburgh Township (excluding the municipal tip located to the north-east of the 

Metropolitan Colliery) and therefore the potential for cumulative industrial noise is minimal. 

Blast Emissions 

Underground Blasting: Use of explosives is not required for existing or proposed general 

underground coal mining. Occasionally the existing continuous miner encounters geological 

structures that are broken up by using very low explosive masses. 

The NSW Department of Environment and Climate Change’s (DECC’s) “Assessing Vibration: A 

Technical Guideline” dated February 2006 does not address blast-induced effects. However, 

Australian Standard AS 2187.2 - 2006 “Explosive - Storage and use Part 2: Use of Explosives - 

Appendix J” does provide guidance on relevant procedures for assessing the blast-induced noise 

and vibration effects on buildings and their occupants. 



Revision 0 




(10-5055R1) 31 July 2008 Page 1

The DECC currently adopts the Australia and New Zealand Environment Council Committee 

(ANZECC) “Technical Basis for Guidelines to Minimise Annoyance due to Blasting Overpressure 

and Ground Vibration” dated September 1990 for assessing potential annoyance from blast 

emissions during daytime hours. 

The assessment of blast emission impacts outside the hours advocated by ANZECC remains 

according to the “Environmental Noise Control Manual” (ENCM) (EPA, 1994) Chapter 154 Noise 

Control Guideline - Blasting. 

Off-site Transport Noise 

Road Traffic: The existing site access and coal haulage routes remain unaltered by the Project 

and mine generated employee and materials movement along these public roads are not 

increased significantly by the Project operation. Slight traffic increases are anticipated to occur 

during Project construction and operation and are therefore assessed in accordance with the 

DoP’s requirements. 

The NSW “Environmental Criteria for Road Traffic Noise” (ECRTN 1999) provides non-mandatory 

procedures for setting acceptable LAeq noise levels on arterial, collector and local roads and 

guidelines for assessing noise impacts from off-site road traffic. 

Rail Traffic: The Rail Corporation NSW (RailCorp) operates the South Coast rail network in 

NSW. Noise emissions from the railway are regulated via RailCorp’s Environment Protection 

Licence (EPL No 12208, review date 17 December 2012). 

1.2 Current Approvals 

The Metropolitan Colliery is regulated via the DECC EPL Licence No 767 (review date 

9 September 2009) and associated Pollution Reduction Program (PRP) requirements. The current 

EPL includes PRP 12 - Stage 2 Noise Investigation and Mitigation Program (Attached as 

Appendix A1). 

While the EPL does not nominate specific regulatory noise limits, PRP 12 nominates provisional 

noise criteria (noise goals) as presented in Table 1. Measured background noise levels in the 

absence of the Metropolitan Colliery operations are further discussed in Section 4 and project 

specific noise assessment criteria are presented in Table 14.

In accordance with the requirements of the PRP12, HCPL forwarded Heggies Report 10-5055-R3 

“PRP 12 Noise Reduction Programme - Stage 2 Noise Mitigation Investigation” dated 

31 March 2008 to the DECC (the PRP 12 Study). PRP 12 Study major findings include: 

• The Metropolitan Colliery’s existing noise emissions are well above the DECC’s PRP 12 noise 

goals and it is not reasonable and feasible to achieve the nominated goals in the absence of 

some major change such as complete replacement and relocation of the CHPP building and 

associated materials handling plant and equipment. 

• HCPL conduct a Washery Building Noise Control Engineering Feasibility Assessment and 

implement noise controls as identified by the assessment. HCPL investigate coal reject and 

product truck subcontract dates and options for variations with respect to noise emissions. 



Revision 0 




(10-5055R1) 31 July 2008 Page 2

• HCPL to implement a continuous noise improvement program for the major surface facilities 

area including a low noise maintenance replacement and procurement policy. 

• HCPL to consult with DECC in relation to setting revised noise goals for the on-going 

operation of the Metropolitan Colliery and reasonable and feasible noise reduction targets. 

• HCPL revisit the above program at any time, subject to the progress and outcomes of the 

proposed Project. 

The PRP 12 Study report was prepared independently of HCPL’s plans for the Project, however 

as anticipated, it is now appropriate to draw upon the PRP 12 Study major findings, which have 

been incorporated into this Project noise impact assessment where consistent with the EARs and 

the NSW INP guidelines. 

2 PROJECT OVERVIEW 

2.1 Overview of Project Operations 

The Project general arrangement and an indication of the progressive development of the Project 

longwalls over the life of the Project are shown in Appendix B1. The general arrangement of the 

Project has been designed to maximise the utilisation of existing Metropolitan Colliery 

infrastructure. The major surface facilities to be upgraded or added are shown in Appendix B2. 

The main activities associated with development of the Project would include: 

• Ongoing surface and underground exploration activities in the Project underground mining 

area and surrounds. 

• Continued development of underground mining operations within existing HCPL mining and 

coal leases (and associated sub-leases) and two new Mining Lease Application areas (MLA 1 

and MLA 2). 

• Upgrade of the existing mining and materials handling systems (eg longwall machinery and 

conveyors) to facilitate an increased run-of-mine (ROM) coal production rate (up to 

approximately 3.2 million tonnes per annum [Mtpa]). 

• Upgrade of the CHPP to facilitate increased production of washed coal (approximately 

2.8 Mtpa), including the addition of a beneficiation circuit to produce a new thermal coal 

product. 

• Continued transport of coal reject to the Glenlee Washery for emplacement by Sada, with 

annual road movements capped at the existing maximum rate. 

• Continued transport of product coal by road to Coalcliff and Corrimal coking plants, with 

annual road movements capped at the existing maximum rate. 

• Construction of a coal reject paste backfill plant and associated coal reject stockpile, 

pumping, pipeline and underground delivery systems to facilitate the underground 

emplacement of coal reject materials as an integrated component of the longwall mining 

operation. 

• Train loading and train movements associated with the transport of product coal to Port 

Kembla 24 hours per day and seven days per week. 

• Surface access within the Woronora Special Area and surrounds that is required for the 

environmental monitoring, management and remediation of mine subsidence. 

• Upgrade and/or extension of the existing supporting infrastructure systems (eg underground 

access, water management, ventilation and electrical systems) as required. 

• Other associated minor infrastructure, plant, equipment and activities. 

The Project would extend the life of the Metropolitan Colliery by approximately 25 years.

2.2 Project Construction and Development Activities 

Infrastructure that is required to support the Project increase in ROM coal production would be 

progressively developed in parallel with ongoing mining operations at the Metropolitan Colliery. 

The Initial Development Schedule is attached as Appendix C1 and the key components that 

would be developed during the initial stages of the Project include: 

• Longwall mining machinery and electricity supply upgrades. 

• Upgrade of materials handling systems (Appendix C2) from approximately 650 tonnes per 

hour (tph) to approximately 1000 tph. 

• Upgrade of the CHPP (Appendix C3) to include a beneficiation circuit (to produce thermal 

coal) and to facilitate increased coal washing and production from approximately 400 tph to 

approximately 600 tph. 

• An additional (short-term) 50,000 tonne ( t) stockpile for coal rejects adjacent to a new 

backfill paste plant (approximately 75 tph) and goaf cavity injection system to dispose of 

excess coal reject material. 

Surface construction works would be undertaken intermittently over a period of up to five years 

generally during daytime hours up to seven days per week. For short periods additional mobile 

equipment would be required.

2.4 Receiver Areas 

The nearest potentially affected residential and community receiver areas beyond the major 

surface facilities area boundary are shown on the Receiver Area Plan (Appendix D1). Selected 

representative assessment locations for each receiver area are presented in Table 3. Local 

Environmental Planning zones are shown on the Local Zoning Plan (Appendix D2).

(10-5055R1) 31 July 2008 Page 5

Table 3 also presents the nominated noise amenity zones based on the INP’s Chapter 2 Industrial 

Noise Criteria and the INP’s Application Notes (July 2006) in relation to the selection of 

appropriate noise amenity zones - refer to INP extracts attached as Appendix D3. The suburban 

noise amenity zone has been nominated for the residential dwellings near the Project boundary. 

However it is likely that some of the nearest dwellings to the existing Metropolitan Colliery 

boundary are within what is termed an urban/industrial interface noise amenity zone, as is 

applicable to residences adjoining existing industrial developments under the INP. 

The remainder of the residential dwellings to the north and beyond the Project boundary are 

generally removed from the immediate and existing Metropolitan Colliery area and therefore well 

within the suburban noise amenity zone.

3 EXISTING METEOROLOGICAL ENVIRONMENT 

3.1 Meteorological Environment 

The NSW INP (2000) Section 5.3, Wind Effects, states: 

“Wind effects need to be assessed where wind is a feature of the area. Wind is considered to be a 

feature where source to receiver wind speeds (at 10 m height) of 3 m/s or below occur for 30 percent of 

the time or more in any assessment period in any season.” 

An assessment of prevailing wind conditions was derived from the meteorological data generated 

by the Commonwealth Scientific and Research Organisation’s (CSIRO’s) Air Pollution Model 

(TAPM) software which has been used to simulate the meteorology of the area and is particularly 

useful in the highly variable terrain at Helensburgh. The dominant seasonal wind speeds and 

directions for an annual period are presented in Appendix E2 for daytime (0700 hours to 

1800 hours), evening (1800 hours to 2200 hours) and night-time (2200 hours to 0700 hours). 

The prevailing winds less than (or equal to) 3 metres per second (m/s) with a frequency of 

occurrence greater than (or equal to) 30% and considered to be relevant to the site in accordance 

with the INP are presented in Table 4. The dominant conditions incorporated into noise 

modelling are underlined.

Note 1: The dominant seasonal wind velocities are underlined. 

The INP Section 5.2, Temperature Inversions, states: 

“Assessment of impacts is confined to the night noise assessment period (10.00 pm to 7.00 am), as this 

is the time likely to have the greatest impact - that is, when temperature inversions usually occur and 

disturbance to sleep is possible.” 

“Where inversion conditions are predicted for at least 30% (or approximately two nights per week) of 

total night-time in winter, then inversion effects are considered to be significant and should be taken 

into account in the noise assessment”. 

An assessment of atmospheric stability conditions has also been prepared from the 

meteorological data set described above. The winter evening and night-time frequency of 

occurrence of atmospheric stability classes are presented in Table 5, together with estimated 

Environmental Lapse Rates (ELR).

In accordance with the INP, the frequency of occurrence of moderate to strong (ie 1.5 to 

>4.0 o C/100 m) winter temperature inversions is less than 30% during the combined evening and 

night-time period and therefore does not require assessment. 

While winter temperature inversions are not necessarily an assessable weather condition in 

accordance with the INP, a review of the local topography and together with the prevalence of 

light west to north-westerly winds is likely to produce coastal strength weak to moderate 

temperature inversions and associated drainage flow during winter. 

3.2 Environmental Noise Model Meteorological Parameters 

The noise modelling meteorological parameters presented in Table 6 are based on analysis of the 

TAPM meteorological data set and field measurements carried out during noise monitoring. In this 

case, the observed meteorological conditions at Helensburgh are generally consistent with the 

default parameters presented in the INP Section 5 Meteorological Conditions.

In summary, evening and night-time north to north-easterly breezes prevail for significant periods 

during warmer seasons. 

During the cooler seasons weak to moderate temperature inversions and associated west to 

north-westerly drainage flows prevail during night-time for less significant periods of time. The 

north-westerly drainage airflow is likely to diminish noise emissions from the existing Metropolitan 

Colliery and the proposed Project as residences are mostly located to the south, west and north 

of the site.

4 EXISTING BACKGROUND AND TRAFFIC NOISE ENVIRONMENT 

The following subsections outline the results of relevant ambient and background noise 

monitoring conducted for this study and for the PRP 12 Study, where relevant. 

4.1 Background Monitoring in the Absence of the Metropolitan Colliery 

2006/2007 

A background noise monitoring programme was conducted in December 2006 coinciding with the 

Christmas/New Year Colliery shutdown to quantify background noise levels (ie all noise sources) 

and to estimate industrial noise only (ie in the absence of transport, natural and domestic noise) at 

four representative residential locations in the vicinity of the Metropolitan Colliery. 

In order to supplement the unattended logger measurements and to assist in identifying the 

character and duration of the noise sources, operator-attended daytime, evening, and night-time 

surveys were also conducted at all four logging locations. The measurement methodology and 

analysis procedures are described in Appendix F1. The operator-attended measurement results 

are summarised in Table 7.

4.4 Ambient Traffic Noise Monitoring Inclusive of the Metropolitan Colliery 

March 2007 

An ambient traffic noise monitoring programme was conducted in March 2007 to quantify 

ambient noise levels (ie all noise sources) and to estimate traffic noise only (ie total existing 

vehicles) at three representative residential locations along the existing off-site haulage route. 

The measurement methodology and analysis procedures are described in Appendix G1. The 

unattended noise logger data from each monitoring location and the on-site weather conditions 

were analysed on a daily basis and presented graphically as statistical 24-hour ambient noise 

profiles in Appendix G2. 

The ambient traffic noise data were then processed in accordance with the requirements of the 

ERTNC Policy to derive the daytime, night-time and peak hourly levels as presented in Table 12, 

normalised to 30m and 15m offset and facade corrected by 2.5 dBA.

4.5 Residents Noise Complaints Summary 

The Metropolitan Colliery maintains a complaints register as part of its environmental 

management and community relations protocol. A listing of noise related complaints are 

presented in Appendix E1 and summarised as follows: 

• During 2005 and 2006, community noise concerns generally related to on-site fixed plant 

noise emissions (three and six noise complaints respectively). 

• During 2007, community noise concerns generally related off-site truck transport noise (two 

noise complaints). 

5 NOISE ASSESSMENT CRITERIA AND METHODOLOGY 

5.1 Construction Assessment Criteria 

The assessment of impact from on-site construction works remains according to the EPA’s 

ENCM (1994) Chapter 171 Noise Control Guideline - Construction Site Noise (Appendix H). The 

ENCM provides noise limits for construction periods of up to 26 weeks. As the duration of the 

construction works is greater than 26 weeks, the EPA suggests that the construction noise 

emission should generally not exceed the background level by more than 5 dBA. As the Project 

construction activities would extend over approximately 5 years, construction noise has been 

assessed by incorporation in the Year 3 operational scenario (Sections 8 and 9). 



Revision 0 




(10-5055R1) 31 July 2008 Page 13

5.2 Operating Assessment Criteria - Sleep Disturbance 

The INP does not specifically address sleep disturbance from high noise level events. 

The EPA’s ECRTN (EPA 1999) recognised that the current sleep disturbance criterion of an 

LA1(1minute) not exceeding the LA90(15minute) by more than 15 dBA is not ideal. Nevertheless, as 

there is insufficient evidence to determine what should replace it, DECC will continue to use it as 

a guide to identify the likelihood of sleep disturbance. This means that where the criterion is met, 

sleep disturbance is not likely, but where it is not met, a more detailed analysis is required. 

The DECC’s interim “Sleep Disturbance Noise Criteria Guideline” dated 22 June 2004 indicates 

that the LA1(1minute) level 15 dBA above the RBL is a suitable screening criteria for sleep 

disturbance for the night-time period. In practice, sleep disturbance is assessed as the 

emergence of the LA1(1minute) level above the LA90(15minute) prevailing at the time as described in 

the guideline and consistent with the EPA’s ECRTN Appendix B Section B5. 

The INP’s more recent Application Notes (July 2006) indicate that a more detailed analysis should 

cover the maximum noise level or LA1(1minute), that is, the extent to which the maximum noise level 

exceeds the background level and the number of times this happens during the night-time period. 

Some guidance on possible impacts is contained in the review of research results in the 

appendices to the ECRTN. Other factors that may be important in assessing the extent of 

impacts on sleep include: 

• How often high noise events will occur. 

• Time of day (normally between 2200 hours and 0700 hours). 

• Whether there are times of day when there is a clear change in the noise environment (such 

as during early morning shoulder periods). 

The LA1(1minute) descriptor is meant to represent a maximum noise level measured under “fast” 

time response. DECC will accept analysis based on either LA1(1minute) or LAmax. A review of noise 

events from the Metropolitan Colliery’s night-time operations including train movements indicates 

that the maximum (LAmax) levels are typically no greater than 10 dBA above the LAeq(15minute) 

intrusive level when measured at a distant receiver (refer Heggies Report 10-5055-R3 dated 

31 March 2008). 

Therefore, it is considered that the INP-based intrusive criteria would be the controlling factor in 

determining compliance for the Project. This relationship enables the noise assessment process 

to focus on the setting and impact assessment of INP-based intrusive noise and amenity levels 

which aim to minimise annoyance at noise sensitive receiver locations. 

5.3 Operating Assessment Criteria - Intrusive Noise and Amenity Levels 

The DECC has regulatory responsibility for the control of noise from “scheduled premises” 

(Metropolitan Colliery is a scheduled premises) under the Protection of the Environment 

Operations Act 1997. In implementing the INP the DECC has two broad objectives: 

• Controlling intrusive noise impacts in the short term. 

• Maintaining noise level amenity for particular land uses over the medium to long term. 

The INP prescribes detailed (but non-mandatory) calculation routines for establishing “project 

specific” LAeq(15minute) intrusive criteria and LAeq(period) amenity (ie non-transport related) criteria 

for new and existing developments at potentially affected receivers. 



Revision 0 




(10-5055R1) 31 July 2008 Page 14

Ideally, the intrusive noise emission should generally not exceed the background level by more 

than 5 dBA. Similarly, the amenity level should generally not exceed the specified INP 

“acceptable” or “maximum” noise level appropriate for the particular locality and land use as 

shown in Table 13.

As described in Section 2.4, some of these locations could be considered to be within an urban/industrial

External criteria equivalent to internal criteria plus 10 dBA. 

In accordance with the INP’s Chapter 2 Industrial Noise Criteria in conjunction with the INP’s 

Application Notes (July 2006), the “project specific” intrusive and amenity assessment criteria for 

the residential, commercial and industrial receiver areas are presented in Table 14. 

For the purposes of assessing noise impacts at the nearest dwellings to the Project boundary, the 

DECC’s PRP 12 noise goals have been adopted. These dwellings due to their locations are most 

exposed to the existing noise of the Metropolitan Colliery when it is operating. 

As discussed in Section 2.4, the suburban noise amenity zone has been adopted for all 

residential dwellings, however, it is likely that some of the nearest dwellings to the existing 

Metropolitan Colliery boundary (as shown in Appendix D1) are within an urban/industrial interface 

noise amenity zone as defined under the INP. 

The recommended intrusive project specific criteria for the remaining dwellings north and beyond 

the Project boundary are relatively lower than the criteria for the nearest dwellings during the 

daytime, evening and night-time periods by 3 dBA, 2 dBA and 5 dBA respectively.

Note 1: 


The INP states that these criteria have been selected to preserve the amenity of at least 90% of 

the population living in the vicinity of industrial noise sources from the adverse effects of noise for 

at least 90% of the time. Provided the criteria in the INP are achieved, then most people would 

consider the resultant noise levels acceptable. 

In those cases where the INP project specific assessment criteria are not achieved, it does not 

automatically follow that all people exposed to the noise would find the noise unacceptable. In 

subjective terms, exceedances of the INP project specific assessment criteria can be generally 

described as follows (where noise levels are predicted to increase as a result of a new 

development): 

• Negligible noise level increase 5 dBA (noticeable by most people). 

It should be noted that the Project noise emissions are predicted to fall at most locations by 

comparison with the existing Metropolitan Colliery operation (refer Section 8). Therefore the 

above would be reversed in most cases (ie some receptors would be expected to notice 3 dBA to 

5 dBA Project noise reductions, while most receptors would notice Project noise reductions of 

5 dBA or more).

5.4 Noise Impact Assessment Methodology 

In view of the foregoing, Table 15 presents the methodology for assessing noise levels which may

For the purposes of assessing the potential noise impacts, the management and affectation 

criteria are further defined as follows: 


Depending on the degree of exceedance of the project specific criteria (1 dBA to 5 dBA) noise 

impacts could range from negligible to moderate, in cases of a new facility or increased noise 

levels from an existing facility. As the Metropolitan Colliery is an existing facility and Project noise 

emissions are predicted to decrease at most assessed receivers by comparison to the existing 

emissions (Section 8), community responses are expected to differ. 

Notwithstanding, it is recommended that management procedures be implemented including: 

• Noise monitoring on site and within the community. 

• Prompt response to any community issues of concern. 

• Refinement of on-site noise mitigation measures and mine operating procedures where 

practical. 

Noise Affectation Zone 

Exposure to noise levels corresponding to this zone may be considered unacceptable by some 

land owners, particularly at night in cases of a new facility or increased noise levels from an 

existing facility. As the Metropolitan Colliery is an existing facility and Project noise emissions are 

predicted to decrease at most assessed receivers by comparison to the existing emissions 

(Section 8), community responses are expected to differ. 

Notwithstanding, it is recommended that HCPL explore the following: 

• Discussions with relevant land owners to assess concerns and define responses. 

• Consideration of implementation of acoustical mitigation at receivers. 

• Negotiated agreements with land owners, where required. 

6 PROJECT NOISE MODEL 

Project noise modelling has utilised the detailed noise model developed for the Metropolitan 

Colliery PRP 12 Study. Where relevant to this Project noise assessment, aspects of the PRP 12 

Study model preparation are outlined below. 



Revision 0 




(10-5055R1) 31 July 2008 Page 17

6.1 Metropolitan Colliery Noise Model Establishment Procedure 

The Metropolitan Colliery computer model was developed for the PRP 12 Study to incorporate 

the significant noise sources associated with the surface facilities. Additionally, surrounding 

terrain, aspects of the built environment and nearby receiver areas were also included in the 

model. 

The Metropolitan Colliery computer model was prepared using the SoundPLAN noise model 

utilising the CONCAWE algorithm, a commercial software system developed by Braunstein & 

Berndt International. The acoustical algorithms utilised by this software are endorsed national or 

international standards and are therefore accepted by the NSW DECC as suitable for use. 

6.2 PRP 12 Fixed Plant Noise Audit - Sound Power Levels 

In order to establish the Metropolitan Colliery noise model, on-site nearfield noise measurements 

to determine fixed plant sound power levels (SWLs) were conducted on 13 and 

22 November 2007. Noise measurement procedures were guided by the requirements of 

AS 1217.7-1985 “Acoustics - Determination of Sound Power Levels Part 7 Survey Method” 

(AS 1217.7:1985) and the results summarised in Table 16. 

These fixed plant SWLs have been utilised in the Project noise model, where relevant.

6.3 PRP 12 Mobile Equipment Noise Audit - Sound Power Levels 

In order to establish the Metropolitan Colliery noise model, on-site nearfield noise measurements 

to determine mobile equipment SWLs were conducted on 13 and 22 November 2007. Noise 

measurement procedures were guided by the requirements of AS 1217.7:1985 and the results are

6.4 PRP 12 Off-site Noise Model Calibration Procedure 

Off-site noise measurements to determine Colliery noise contributions at selected calibration 

locations were conducted on 13, 22 November 2007 and 26 March 2008. Noise measurement 

procedures were guided by the requirements of AS 1055-1997 “Acoustics - Description and 

Measurement of Environmental Noise” as discussed in Section 4.1. 

A moderate calibration adjustment of 5 dBA has been incorporated into the Metropolitan Colliery 

noise model and is generally consistent with field measurement and modelling results from similar 

materials handling and resource related industrial developments. A smaller calibration adjustment 

of 2 dBA has been applied to haul trucks on Colliery Road, due to the close proximity of this 

activity to the nearest receivers. The above model calibration has been incorporated into the 

Project noise modelling.

6.5 Project Noise Model Scenarios 

The three operating modelling scenarios examined for the Project include significant fixed plant 

and mobile equipment operating concurrently to simulate the likely intrusive emissions and noise 

amenity levels, namely: 

Existing on-site Metropolitan Colliery Operations (for Project comparison 

purposes) including: 

• Nil construction activity. 

• ROM coal production (1.8 Mtpa) with CHPP 400 tph capacity and conveyor handling system 

at current capacity. 

• Coal train loading operations of coking coal (1.4 Mtpa). 

• Coal reject haulage off-site emplacement at Glenlee Washery. 

• Coking coal trucking for off-site delivery to Corrimal and Coalcliff Coke Works. 

Project Year 3 Operations and Construction, including on-site: 

• Construction activity associated with the CHPP upgrade and establishment of the backfill 

paste plant. 

• Increased ROM coal production (2.13 Mtpa) with CHPP upgraded to 600 tph capacity and 

beneficiation circuit operating but conveyor handling system unchanged. 

• Coal train loading operations of coking coal (1.69 Mtpa) and thermal coal (0.03 Mtpa). 

• Coal reject haulage to on-site stockpile at a rate of 40,000 tpa together with trucking for 

off-site emplacement at Glenlee Washery. 


• Progressive implementation of noise controls. 

Project Year 15 Operations, including on-site: 

• Increased ROM coal production (3.19 Mtpa), CHPP upgraded to 600 tph capacity, 

Beneficiation Circuit operating and conveyor handling systems upgraded to 1000 tph. 

• Coal train loading operations of coking coal (2.59 Mtpa) and thermal coal (0.05 Mtpa). 

• Coal reject haulage to backfill paste plant operating at a rate of 0.43 Mtpa. 


• Additional noise controls implemented. 

Note, an average number of heavy vehicle pass-bys along Colliery Road have been included in 

the noise model as part of the on-site Colliery daytime noise. During peak periods the number of 

heavy vehicle movements could potentially be greater than the average number of pass-bys. 

7 PROJECT NOISE MITIGATION MEASURES 

The identification of Project noise mitigation measures and incorporation of these measures in the 

Project noise model (Section 6) has built on the noise mitigation investigations conducted for the 

PRP 12 Study and includes the noise mitigation measures currently being implemented by HCPL. 

Where relevant these are described below.

7.1 PRP 12 Identification of Existing Plant with the Highest Noise 

As part of the PRP 12 Study, the operator-attended measurements discussed in Section 4.1, 

identified the existing Washery Building as the highest contributing Colliery noise source at the 

key dwellings located at 2 Oxley Place (O2) and 53 Parkes Street (P 53). 

It was also determined that the Washery Building has the highest fixed plant SWLs of 117 dBA 

which is emitted over a large surface area, with several existing openings and windows 

particularly on the southern and western facades facing the Oxley Place and Parkes Street 

dwellings. There is line of sight (although heavily timbered) between the upper levels of the 

Washery Building and some of the nearest dwellings on Oxley Place and Parkes Street, allowing 

the Washery’s noise emissions to propagate freely from source to receiver. 

Predictions of the noise contribution of other appreciable (although less significant by comparison 

with the Washery) Metropolitan Colliery noise sources was conducted via computer based noise 

modelling as a component of the PRP 12 Study. 

The results of the fixed and mobile plant audits are provided in Sections 6.2 and 6.3. 

7.2 PRP 12 Investigation of Potential Fixed Plant Noise Controls - Existing 

Operation 

As a component of the PRP 12 Study the current fixed plant SWLs (including any existing noise 

controls) were compared to “technically achievable” low noise emission standards that have been 

demonstrated as sustainable by retrofit (rather than equipment replacement) while still reducing 

the noise at its source (or alternatively very near to the commencement of the noise propagation 

path - eg by enclosure). 

Technically achievable noise control or low emission benchmarks were established by 

researching the results of recent CHPP and mobile fleet noise reduction programmes for other 

mining projects and low noise materials handling technology associated with existing and 

approved coal handling facilities in the Port of Newcastle. 

The coarse washery building, pumps/compressor units, transfer conveyors and large conveyor 

drive assembly were all identified as potential noise reduction targets where the existing source 

noise was appreciably above the technically achievable low noise emission benchmarks. Of 

these, the enclosure of the coarse washery building utilising continuous span 0.47 millimetre (mm) 

Colorbond profile steel cladding (or equivalent) and 50 mm Rockwool sealed in a thin mylar film 

and perforated steel sheeting (or equivalent) was identified as the most potentially effective noise 

control measure by the PRP 12 Study. 

7.3 PRP 12 Mobile Equipment Noise Controls and Management - Existing 

Operation 

As a component of the PRP 12 Study, the measured mobile equipment SWLs (including any 

existing noise controls) were compared to comparable equipment of similar design and operation. 

All items of major mobile equipment surveyed emitted SWLs within the noise emission standard 

by comparison with equivalent equipment with no observed irregularity. Noise reductions are 

technically achievable by noise control retrofitting (rather than equipment replacement) however 

there remains some doubt in relation to the sustainability and on-going operating performance 

impacts of “after market” noise control packages.

The PRP 12 Study concluded that while there remains potential to install noise control kits (ie high 

performance mufflers, acoustic louvres to radiator fan, engine dampening and track tensioning) to 

existing front-end loaders and tracked dozers, such measures were considered unwarranted 

particularly as noise arising from fixed plant sources were the major contributors at the nearest 

receivers. 

It is also technically achievable that future mobile equipment (ie replacement or upgrade) be the 

subject of a continuous noise improvement programme as described in Section 7.6. An example, 

may include future replacement or upgrade (ie at the next subcontract renewal date) to the 

existing offsite truck haulage fleets (ie coal reject and coking coal) where the use of new and 

efficient articulated vehicles are demonstrated to emit up to 6 dBA lower noise emissions by 

comparison with the existing fleets. 

7.4 Current HCPL Noise Control Initiatives - Existing Operation 

In accordance with the findings of the PRP 12 Study, HCPL is currently examining the relative 

feasibility of a number of noise mitigation measures to reduce noise emissions from the coarse 

washery building. The preliminary results of this assessment and HCPL’s proposed noise 

mitigation measures for the coarse washery building have been included in this Project noise 

assessment, where relevant. A number of these measures are expected to be implemented prior 

to the DoP assessment of the Project Environmental Assessment and have been incorporated in 

the Project noise model on this basis. 

7.5 Project Noise Control Measures Incorporated in the Model 

The Project, if approved, would provide for a further 25 years of operation at the Metropolitan 

Colliery. The extended life of the operation and the various surface facilities upgrade works would 

provide an opportunity to introduce further practicable noise controls as a component of the 

Project upgrades. 

HCPL would implement a range of noise controls and/or purchase replacement low noise 

equipment and implement a continuous noise improvement programme to reduce noise 

emissions at the Metropolitan Colliery. The timing of the implementation of the noise controls 

would be dependant on the actual progressive development of the Project and the measures 

would be implemented in order to facilitate compliance with relevant noise specifications. 

Specific fixed plant and mobile equipment noise control measures incorporated in the model to 

meet specified SWL emissions and/or modelled levels at the nearest private receptors include: 

• Enclosure of the coarse washery building (HCPL has commenced aspects of this work). 

• The Project CHPP upgrade to include the installation of modern low-noise equipment where 

practicable, and/or additional sound insulation, or specific mitigation of key noise sources 

(eg drives). 

• Replacing existing exhaust silencers on pumps and compressors with high performance 

mufflers. 

• Relocating or enclosing the MD1 conveyor drive fan as a component of Project conveyor 

upgrades. 

• Partial enclosure or construction of a nearfield barrier to the south/west of the MD1 conveyor 

drive as part of Project conveyor upgrades. 

• Implementation of a low noise conveyor idler replacement system on surface transfer 

conveyors as a component of Project conveyor upgrades. 

• Enclosure of the new paste backfill plant to minimise noise emissions.

(10-5055R1) 31 July 2008 Page 23

• Use of modern low-noise front-end loader and 30 t off-road trucks for on-site coal reject 

haulage (between the CHPP and the temporary coal reject stockpile or paste backfill plant). 

Specific operational noise control measures incorporated in the noise model to meet specified 

SWL emissions and/or modelled levels at the nearest private receptors include: 

• Project surface construction activities to be restricted to daytime hours. 

• No off-site road haulage of product coal or coal reject during the evening or night-time 

periods (continuation of an existing Metropolitan Colliery operational noise control measure). 

• No haulage of coal reject between the CHPP and the temporary stockpile or between the 

CHPP and the backfill paste plant to be undertaken in the evening and night-time periods. 

• Use of broadband noise alarms on existing and future equipment adjusted to meet 

occupational health and safety (OHS) requirements. 

The above measures would be implemented progressively eg conveyor upgrade and mitigation 

would not occur until after Year 3 (refer Initial Development Schedule). For the purposes of noise 

impact assessment, the design maximum LAeq SWLs are presented in Table 18 for the all 

acoustically-relevant items of plant and equipment for the Project (once upgraded).

7.6 Continuous Noise Improvement Programme 

In addition to the noise controls described in Sections 7.4 and 7.5, HCPL would commit to 

implement a Project continuous noise improvement programme in accordance with the 

requirements of the EPL, involving an Acoustical Design, Procurement, Construction and 

Commissioning process for the Project, including: 

• Noise limits and acoustical specifications 

• Best Available Technology for each Stage of development. 

• Environmental and OHS acoustical specifications for all equipment types. 

• Desktop design validation and supplier shop testing 

• Equipment suppliers must demonstrate acoustical conformance during tender phase. 

• Environmental and OHS acoustical shop testing during procurement phase. 

• In-situ acceptance testing 

• Environmental and OHS acoustical field testing during plant commissioning. 

• Refitting and or replacement in the event of non-compliance. 

• Computer-based acoustical modelling 

• Acoustical modelling of installed plant using actual achieved SWLs. 

• Preparation of detailed acoustical compliance report for each Stage of development. 

• Noise emission monitoring and reporting 

• On-site and off-site operator-attended noise surveillance measurements of acoustically 

significant plant. 

• In the event of community concerns 

• Prompt response and targeted noise monitoring where required. 

• Refinement of on-site noise operating procedures where practicable. 

8 INTRUSIVE NOISE IMPACT ASSESSMENT 

The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential 

receptors and other suburban landuses. The Project upgrades to the major surface facilities area 

would not significantly change the location, nature or the main characteristics of the Metropolitan 

Colliery on-site noise emissions. Therefore, for comparative purposes, modelled intrusive noise 

predictions for the Project (Year 3 and Year 15) have been compared to modelled intrusive noise 

emissions for the existing Metropolitan Colliery in the subsections below for the daytime, evening 

and night-time periods with the application of significant weather conditions in accordance with 

the INP. 

8.1 Daytime Existing Metropolitan Colliery and Project Year 3 and 15 

The predicted daytime intrusive noise from the existing Metropolitan Colliery and proposed 

Project Year 3 and Year 15 operations from all on-site activities including all fixed plant and 

support mobile equipment and train loading are presented in Table 19. Table 19 incorporates 

examination of the contribution of on-site road haulage of coal or coal reject on Colliery Road to 

noise levels at receptors (ie model predictions have been generated with and without this 

equipment operating).

Existing Metropolitan Colliery Noise 

During daytime with Colliery Road coal haulage (ie trucks operating) the existing Metropolitan 

Colliery noise levels at the nearest receivers are up to 12 dBA (O14, O16) above the criteria. In 

the absence of coal haulage (ie trucks not operating) the existing noise levels are up to 9 dBA (O2 

and O4) above the criteria. 

Predicted Project Noise 

Following the implementation of potential noise controls (Section 7) the Project Year 3 and 15 

noise levels are predicted to reduce at all assessed receivers to the west and south of the site. 

Project noise levels at receivers near the Project boundary to the north are generally predicted to 

remain unchanged due to the inclusion of train loading activities in the model, which are in close 

proximity and dominate noise emissions at these locations. 

8.2 Evening Existing Metropolitan Colliery and Project Year 3 and 15 

The predicted evening intrusive noise from the existing Metropolitan Colliery and proposed 

Project Year 3 and Year 15 operations from all on-site activities including all fixed plant, support 

mobile equipment, and train loading are presented in Table 20. No coal or coal reject road 

haulage is to be undertaken in the evening.

Existing evening Colliery noise levels are lower in the absence of coal and coal reject haulage, 

however the existing noise levels at the nearest receivers are up to 16 dBA (O4) above the 

evening criteria. 


Following the implementation of Project noise controls (Section 7) the Project Year 3 and 15 

noise emissions are predicted to reduce at all assessed receivers to the west and south of the 

site. Project noise levels at receivers near the Project boundary to the north are generally 

predicted to remain unchanged due to the inclusion of train loading activities in the model, which 

are in close proximity and dominate noise emissions at these locations. 

8.3 Night-time Existing Metropolitan Colliery and Project Year 3 and 15 

The predicted night-time intrusive noise from the existing Metropolitan Colliery and proposed 

Project Year 3 and Year 15 operations from all on-site activities including fixed plant, support 

mobile equipment, and training loading are presented in Table 21. No coal or coal reject road 

haulage is to be undertaken during the night-time.

Existing night-time Colliery noise levels are lower in the absence of coal or coal reject haulage, 

however the existing noise levels at the nearest receivers are up to 16 dBA (O4) above the nighttime 

criteria. 



noise emissions are predicted to reduce at all assessed receivers to the west and south of the 

site. Project noise levels at receivers near the Project boundary to the north are generally 

predicted to remain unchanged due to the inclusion of train loading activities in the model, which 

are in close proximity and dominate noise emissions at these locations. 

The Year 3 night-time LAeq(15minute) intrusive noise contours during calm weather is presented as 

Appendix I. The Year 3 night-time LAeq(15minute) intrusive noise contours during 3 m/s north wind 

is presented as Appendix J. The calculation of the noise contours involves numerical 

interpolation of a noise level array with a graphical accuracy of up to approximately ±2 dBA. This 

means that in some cases the contour locations presented in Appendices I and J will differ from 

the tabulated data which have highest accuracy. 

8.4 Project Year 3 and 15 - Ventilation Shaft Noise 

As shown on the General Arrangement Plan (Appendix B1) the existing Ventilation Shaft No 3 is 

located adjacent to the F6 Southern Freeway. An additional Ventilation Shaft (No 4) is required by 

the Project and would be also be located adjacent to the F6 Southern Freeway and approximately 

3 km north of Ventilation Shaft No 3. 

The nearest residential receivers are located more than 1 km to the east of the proposed 

Ventilation Shaft No 4, where the night-time noise contribution is calculated to be

During the night-time the existing Metropolitan Colliery noise amenity levels near the Project 

boundary are up to 13 dBA above the criterion. As discussed in Section 2.4, it is likely that some 

of these dwellings are within the urban/industrial interface noise amenity zone (where the 

acceptable criterion is 50 dBA). 



noise emissions are predicted to reduce at all assessed receivers except those near the Project 

boundary to the north where train loading noise continues to dominate. 

10 BLAST EMISSIONS IMPACT ASSESSMENT 

10.1 Human Comfort and Damage Criteria 

Appendix J of AS 2187: Part 2-2006 “Explosives - Storage and Use - Part 2: Use of Explosives” 

provides detailed guidance in assessing blast induced ground (and structural) vibration and 

airblast effects on buildings and their occupants. 

Recommended vibration limits are generally based on international standards (or studies) as 

presented in Appendix J Tables J4.5(A) and J4.5(B), for human comfort and structural damage 

respectively. Similarly, recommended human comfort and structural damage airblast limits are 

presented in Appendix J Tables J5.4(A) and J5.4(B) respectively. 

However, ground vibration and airblast levels which cause human discomfort are generally lower 

than the recommended structural damage limits. Therefore compliance with the lowest applicable 

human comfort criteria ensures that the potential to cause structural damage is minimal. 

Hence, the DECC continues to adopt the ANZECC “Technical Basis for Guidelines to Minimise 

Annoyance due to Blasting Overpressure and Ground Vibration” dated September 1990 for 

assessing potential annoyance from blast emissions during daytime hours, as follows: 

• The recommended maximum level for airblast is 115 dB Linear. 

• The level of 115 dB Linear may be exceeded on up to 5% of the total number of blasts over a 

period of 12 months. The level should not exceed 120 dB Linear at any time. 

• The recommended maximum for ground vibration is 5 millimetres per second (mm/s), Peak 

Vector Sum vibration velocity (PVS). It is recommended however, that 2 mm/s (PVS) be 

considered as the long-term regulatory goal for the control of ground vibration. 

• The PVS level of 5 mm/s may be exceeded on up to 5% of the total number of blasts over a 

period of 12 months. The level should not exceed 10 mm/s at any time. 

• Blasting should generally only be permitted during the hours of 0900 hours to 1700 hours 

Monday to Saturday. Blasting should not take place on Sundays and public holidays. 

• Blasting should generally take place no more than once per day. 

The assessment of blast emission impacts outside the hours advocated by the ANZECC remains 

according to the ENCM Chapter 154 Noise Control Guidelines - Blasting presented in Table 25. 

Note, the suggested time of blasting in Table 25 has been modified to be consistent with the 

ANZECC guidelines.

10.2 Excavation Blast Design and Prediction Methodology 

As discussed in Section 1.1, use of explosives is not required for general underground coal 

mining. Occasionally the continuous miner encounters geological structures that are broken up 

by using very low explosive masses. An assessment of the potential vibration and airblast 

emissions arising from the underground excavation blasting has been based on the typical blast 

design parameters presented in Table 26.

By adopting the anticipated excavation blast design parameters, the vibration and airblast 

emissions can be predicted using the relevant vibration and airblast formula presented in 

AS 2187.2-2006. Airblast emission arising from underground blasting would propagate from the 

excavation site and release to the surface via the nearest ventilation shafts. But before reaching 

the surface, airblast noise is attenuated due to underground confinement and a conservative 

25 dB loss has been assumed for this assessment. 

The relevant formulae are as follows: 

PVS = 3,272 (R/Q 1/2 ) -1.60 

dBLpk = 148.4 - 24(log10R - log10Q) 

where, 

PVS = mm/s 

dBLpk = Peak airblast dBLinear inclusive of 25 dB attenuation due to underground 

confinement 

R = Distance between charge and receiver (m) 

Q = Charge mass per delay (kg) 

10.3 Underground Excavation Blast Emissions Prediction 

The standard formulae have been used to predict vibration and airblast emissions as presented in 

Table 27.

Evening 105 dBLpk 140 m 2 mm/s 320 m 

Night-time 95 dBLpk 360 m 1 m/s 500 m 

Based on the foregoing, airblast emissions arising from underground excavation blasting are 

predicted to meet the most stringent night-time criteria of 95 dBLpk at a distance of 360 m from 

the nearest ventilation shaft. As there are no residential dwellings located within 360 m from the 

proposed Ventilation Shaft No 4, airblast noise impacts are likely to be minimal (which is 

consistent with the with existing Metropolitan Colliery excavation blasting practices). 

Similarly, ground vibration levels are predicted to meet the most stringent night-time criteria of 

1 mm/s at a distance of 500 m from the blast site. As all excavation blasting is conducted at least 

400 m below the surface, vibration impacts are also likely to be minimal (which is also consistent 

with the existing Metropolitan Colliery excavation blasting practices and experience). 

11 OFF-SITE TRANSPORT 

11.1 Road Transport 

Traffic Noise Criteria 

Based on the ECRTN dated May 1999, Lawrence Hargrave Drive is classified as a “sub-arterial 

road” and Parkes Street as a “collector”, road. The applicable noise criteria are presented in 

Table 28. 

The traffic noise monitoring was conducted to establish the existing traffic noise environment 

inclusive of the existing Metropolitan Colliery operations and summarised in Section 4.4. The 

existing total traffic noise levels generally already exceed the relevant criteria at nominal off-set 

distance of 30 m from Lawrence Hargrave Drive and 15 m from Parkes Street, Helensburgh.

Traffic Noise Impact - Lawrence Hargrave Drive 

For the purposes of noise impact assessment, the existing traffic and additional Project 

construction and operation daily traffic flows together with the morning and afternoon peak hour 

flows are presented in Table 30. The percentage increase arising from the Project contributed 

traffic is shown in brackets.

The maximum increase arising from the additional Project related traffic flow is only 0.4% during 

the construction and operation morning peak hour. The anticipated 0.4% increase in vehicle 

movements corresponds to a negligible (

The maximum increase arising from the additional Project related traffic flow is only 1.9% during 

construction and operation morning peak hour. The anticipated 1.9% increase in vehicle 

movements corresponds to a negligible (0.1 dB) increase in the existing traffic noise levels and 

therefore any Project related traffic noise impacts are likely to be acceptable. 

11.2 Rail Transport 

Railway Noise Criteria 

RailCorp operates the South Coast rail network in NSW. Noise emissions from the railway are 

regulated via the RailCorp’s EPL No. 12208. The intent of the relevant EPL conditions is to 

control airborne noise by two principal means: 

• Noise Limits. 

• Management of noise via PRPs. 

EPL Section L6 Noise Limits (note) provides railway operating noise objectives as follows: 

It is an objective of this licence to progressively reduce noise levels to the goals of 60 dB(A)Leq, (24 hr) 

and 85 dB(A) max pass by noise, at one metre from the facade of the nearest affected residential 

property through the implementation of the Pollution Reduction Programs. 

In the development of new works, the licensee is required to work towards the planning goals of 

55 dB(A) Leq, (24 hr) and 80 dB(A) max pass by noise, at one metre from the facade of the nearest 

affected residential property. 

The goals do not represent unobtrusive noise levels. Rather, the objectives recognise that rail 

operations are inherently noisy and represent a compromise between what may be desirable from 

a community point of view (ie maintaining amenity) and what is necessary to enable trains to 

operate. 

Rail Traffic Movements 

The midweek daily existing, additional and cumulative train movements are presented in Table 32 

with the percentage increase arising from the Project additional traffic shown in brackets. Also 

shown are the estimated train operating conditions between Helensburgh and Otford in the 

vicinity of the Project site.

Railway Noise Impact 

The calculation of the daily (24 hour) equivalent continuous noise levels and the maximum passby 

levels have been conducted using a computer prediction model developed by Heggies. This 

model has previously been accepted by the DoP and DECC. 

The prediction model uses characteristic noise levels for the various sources (locomotive engine 

and exhaust noise as a function of throttle notch, wheel/rail noise as a function of train speed, and 

wagon type, etc) at a fixed reference distance. The model then makes adjustments for the train 

length and distance from the track (assuming no barriers) and facade reflection. Parameters 

including the daily LAeq(24hour) and maximum passby level (LAmax) can then be determined by 

summing the effects of the individual noise sources and by incorporating the number of train 

events. 

The midweek daily LAeq(24hour) and maximum (LAmax) noise levels for the existing and cumulative 

train movements are presented in Table 34.

Predicted Truck Vibration Levels 

The vibration levels arising from rubber-tyred on-road haul trucks (e.g. that haul product coal and 

coal reject off-site) can be predicted based on the “Generalized Ground Surface Vibration Curves” 

presented in the “Transit Noise and Vibration Impact Assessment” dated April 1995 prepared for 

the US Department of Transportation. The Project truck transport of coal and coal reject would 

be restricted to daytime hours and the predicted peak component vibration velocities are 

presented in Table 37 together with the relevant criteria for residential dwellings and their 

occupants.

30 m 0.1 mm/s 0.1 mm/s 0.1 mm/s 

5 mm/s 0.5 mm/s 

It is anticipated that trucks travelling at a speed of 40 km/hr (or less) would generate vibration 

levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 3.8 m (or 

greater). 

Similarly, it is anticipated that trucks travelling at a speed of 80 km/hr (or less) would generate 

vibration levels below the most stringent annoyance risk criterion of 0.5 mm/s at a distances of 

7.5 m (or greater). 

The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by truck 

movements on the public road network at the nearest residential dwellings. 

Predicted Train Vibration Levels 

Similarly, the vibration levels arising from locomotive powered freight trains can be predicted 

based on the foregoing reference document. Project train movements would be 24 hours per day 

and the predicted peak component vibration velocities are presented in Table 38 together with 

the relevant risk criteria for residential dwellings and their occupants.

It is anticipated that trains travelling at a speed of 40 km/hr (or less) would generate vibration 

levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a distances of 

60 m (or greater). 

Similarly, it is anticipated that trains travelling at a speed of 80 km/hr (or less) would generate 

vibration levels below the most stringent night-time annoyance risk criterion of 0.2 mm/s at a 

distances of 90 m (or greater). 

The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded by train 

movements on the South Coast rail network at the nearest residential dwellings. 

Offsite Road and Rail Vibration Impact Assessment 

The above predictions of potential off-site rail and road vibration impacts are based on the upper 

range of measurement results under general standards and conditions. Where road surfaces or 

rail facilities are poorly maintained, additional vibration effects may result (eg if potholes occur in 

the road surface or rail corrugations occur on the track surface). 

As the Project would not result in significant increases in the total number of heavy vehicle 

movements on the public road network (Section 11.1) or total rail movements on the South Coast 

rail network (Section 11.2), the existing vibration effects of heavy vehicle movements on the 

public road network and vibration effects of trains on the rail network would be generally 

unchanged by the Project. 

12 SUMMARY OF FINDINGS 

12.1 Construction Noise 

As the duration of the Project construction activities would extend over approximately 5 years, 

construction noise has been incorporated in the Year 3 operational scenario. Modelled 3 

construction activities are considered representative of likely cumulative construction and 

operational noise. 

12.2 Operating Noise Assessment Procedure 

In accordance with the INP’s Chapter 2 Industrial Noise Criteria in conjunction with the INP’s 

Application Notes (July 2006), the “project specific” intrusive and amenity assessment criteria for 

the residential, commercial and industrial receiver areas are presented in Table 39. 

For the purposes of assessing noise impacts at the nearest dwellings to the Project boundary, the 

DECC’s PRP 12 noise goals have been adopted. These dwellings due to their locations are most 

exposed to the existing noise of the Metropolitan Colliery when it is operating. 



Revision 0 




(10-5055R1) 31 July 2008 Page 45

As discussed in Section 2.4, the suburban noise amenity zone has been adopted for all 

residential dwellings, however, it is likely that some of the nearest dwellings to the existing 

Metropolitan Colliery boundary are within an urban/industrial interface noise amenity zone as 

defined under the INP. 

Assessed intrusive project specific criteria for the remaining dwellings beyond the Project 

boundary are relatively lower during the daytime, evening and night-time periods by 3 dBA, 2 dBA 

and 5 dBA respectively.

Note 1: 


The INP states that these criteria have been selected to preserve the amenity of at least 90% of 

the population living in the vicinity of industrial noise sources from the adverse effects of noise for 

at least 90% of the time. Provided the criteria in the INP are achieved, then most people would 

consider the resultant noise levels acceptable. 

In those cases where the INP project specific assessment criteria are not achieved, it does not 

automatically follow that all people exposed to the noise would find the noise unacceptable. In 

subjective terms, exceedances of the INP project specific assessment criteria can be generally 

described as follows (where noise levels are predicted to increase as a result of a new 

development): 



Revision 0 




(10-5055R1) 31 July 2008 Page 46

• Negligible noise level increase 5 dBA (Noticeable by most people). 

It should be noted that the Project noise emissions are predicted to fall at most assessed 

receivers by comparison with the existing Metropolitan Colliery operation (refer Section 8). 

Therefore the above would be reversed in most cases (ie some receptors would be expected to 

notice 3 dBA to 5 dBA Project noise reductions, while most receptors would notice Project noise 

reductions of 5 dBA or more. 

12.3 Project Noise Modelling and Mitigation Measures 

The Metropolitan Colliery computer model was developed for the PRP 12 Study to incorporate 

the significant noise sources associated with the surface facilities. Additionally, surrounding 

terrain, aspects of the built environment and nearby receiver areas were also included. 

The three operating modelling scenarios examined for the Project include significant fixed plant 

and mobile equipment operating concurrently to simulate the likely intrusive emissions and noise 

amenity levels, namely: 

• Existing Metropolitan Colliery Operations (for Project comparison) - daytime, evening and 

night-time. 

• Year 3 Operations and Construction - daytime, evening and night-time. 

• Year 15 Operations - daytime, evening and night-time. 

A number of significant specific fixed plant and mobile equipment noise control measures have 

been progressively incorporated in the model to meet specified SWL emissions and/or modelled 

levels at the nearest private receptors, including: 

• Enclosure of the coarse washery building (HCPL has commenced aspects of this work). 

• The Project CHPP upgrade to include the installation of modern low-noise equipment where 

practicable, and/or additional sound insulation, or specific mitigation of key noise sources 

(eg drives). 

• Replacing existing exhaust silencers on pumps and compressors with high performance 

mufflers. 

• Relocating or enclosing the MD 1 conveyor drive fan as a component of Project conveyor 

upgrades. 

• Partial enclosure or construction of a nearfield barrier to the south/west of MD 1 conveyor 

drive as part of Project conveyor upgrades. 

• Implementation of a low noise conveyor idler replacement system on surface transfer 

conveyors as a component of Project conveyor upgrades. 

• Enclosure of the new paste backfill plant to minimise noise emissions. 

• Use of modern low-noise 30 t off-road trucks and front-end loader for on-site coal reject 

haulage (between the CHPP and the temporary coal reject stockpile or paste backfill plant). 



Revision 0 




(10-5055R1) 31 July 2008 Page 47

Specific operational noise control measures incorporated in the noise model to meet specified 

SWL emissions and/or modelled levels at the nearest private receptors include: 

• Project surface construction activities to be restricted to daytime hours. 

• No off-site road haulage of product coal or coal reject during the evening or night-time 

periods (continuation of an existing Metropolitan Colliery operational noise control measure). 

• No haulage of coal reject between the CHPP and the temporary stockpile or between the 

CHPP and the backfill paste plant to be undertaken in the evening and night-time periods. 

• Use of broadband noise alarms on existing and future equipment adjusted to meet OHS 

requirements. 

The above measures would be implemented progressively eg conveyor upgrade and mitigation 

would not occur until after Year 3 (refer Initial Development Schedule). For the purposes of noise 

impact assessment, the design maximum LAeq SWLs are presented in Table 40 for all 

acoustically-relevant items of plant and equipment for the Project (once upgraded).

The Project, if approved, would provide for a further 25 years of operation of the Metropolitan 

Colliery. The extended life of the operation and the various surface facilities upgrade works would 

provide an opportunity to introduce further practicable noise controls as a component of the 

Project upgrades. 



Revision 0 




(10-5055R1) 31 July 2008 Page 48

HCPL would implement a range of noise controls and/or purchase replacement low noise 

equipment and implement a continuous noise improvement programme to reduce noise 

emissions at the Metropolitan Colliery. The timing of the implementation of the noise controls 

would be dependant on the actual progressive development of the Project and the measures 

would be implemented in order to facilitate compliance with relevant noise specifications. 

12.4 Intrusive Noise Impact Assessment 

The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential 

receptors and other suburban landuses (refer Appendix D1). The Project upgrades to the major 

surface facilities area would not significantly change the location, nature or the main 

characteristics of the Metropolitan Colliery on-site noise emissions. 

Therefore, for comparative purposes, modelled intrusive noise predictions for the Project (Year 3 

and Year 15) have been compared to modelled intrusive noise emissions for the existing 

Metropolitan Colliery for the daytime, evening and night-time periods as detailed in Section 8. 

Following the implementation of reasonable and feasible noise controls the Project Year 3 and 15 

noise levels reduce at all assessed receivers to the west and south of the site by significant 

margins (ie 10 dBA or more) at several of the nearest dwellings in Oxley Place and Parkes Street. 

Project noise levels at receivers near the Project boundary to the north are generally predicted to 

remain unchanged due to the inclusion of train loading activities in the model, which are in close 

proximity and dominate noise emissions at these locations. 

While quite significant noise reductions (by comparison with the existing Metropolitan Colliery) are 

predicted through the implementation of the Project noise controls, Project noise emissions 

would remain above the relevant intrusive noise assessment criteria at some of the nearest 

dwellings near the Project boundary. 

A summary of the number of privately owned dwellings where the project specific intrusive criteria 

are exceeded is presented in Table 41 for the daytime, evening and night-time periods.

As shown in Table 41, the number of private residences in the Metropolitan Colliery noise 

affectation zone (ie >5 dBA above intrusive criteria) during the daytime, evening and night-time 

period (15, 29 and 25 residences respectively) would be reduced significantly by the 

implementation of the Project. The total number of residences in the noise affection zone (all 

periods) for the existing operation (29) is predicted to be moderately reduced by Year 3 (to 

20 residences) and be significantly reduced by Year 15 (to 14 residences).

12.5 Noise Amenity Impact Assessment 

As for the intrusive noise assessment, modelled amenity period noise predictions for the Project 

(Year 3 and Year 15) have been compared to modelled noise amenity levels for the existing 

Metropolitan Colliery for the daytime, evening and night-time periods as detailed in Section 9. 

Similarly, following the implementation of reasonable and feasible noise controls, the Project 

Year 3 and 15 noise levels reduce at all assessed receivers to the west and south of the site and 

some by significant margins (ie 10 dBA or more). Project noise levels at receivers to the north are 

generally predicted to remain unchanged due to the inclusion of train loading activities in the 

model, which are in close proximity and dominate noise emissions at these locations. 

While significant noise reductions are achievable through the implementation of potential noise 

controls, Project noise emissions would remain above the suburban noise amenity criteria at 

some of the nearest dwellings near the Project boundary. However, as discussed in 

Section 12.2, it is likely that some of the nearest dwellings to the Metropolitan Colliery boundary 

are within the urban/industrial interface noise amenity zone (where the relevant criteria are 10 dBA 

higher by comparison). 

A summary of the number of privately owned dwellings where the suburban noise amenity criteria 

is exceeded is presented in Table 42 for the daytime, evening and night-time periods.

As shown in Table 42, the number of private residences in the Metropolitan Colliery noise 

affectation zone (ie >5dBA above acceptable amenity criteria) during the evening and night-time 

periods (3 and 14 residences respectively) would be reduced significantly by the implementation 

of the Project. The total number of residences in the noise affection zone (all periods) for the 

existing operation (14), is predicted to be reduced to 3 during Year 3 and no exceedances of the 

acceptable amenity criteria are predicted for Year 15. 

12.6 Blast Emission Impact Assessment 

Use of explosives is not required for existing or proposed general underground coal mining. 

Occasionally the existing continuous miner encounters geological structures that are broken up 

by using very low explosive masses. Airblast emission arising from underground blasting would 

propagate from the excavation site and release to the surface via the nearest ventilation shafts. 

But before reaching the surface, airblast noise is attenuated due to underground confinement. 

Airblast emissions arising from underground excavation blasting are predicted to meet the most 

stringent night-time criteria of 95 dBLpk at a distance of 360 m from the nearest ventilation shaft. 

As there are no residential dwellings located within 360 m from the proposed Ventilation Shaft 

No 4, airblast noise impacts are likely to be minimal (which is consistent with the existing 

Metropolitan Colliery excavation blasting practices). 



Revision 0 




(10-5055R1) 31 July 2008 Page 50

Similarly, ground vibration levels are predicted to meet the most stringent night-time criteria of 

1 mm/s at a distance of 500 m from the blast site. As all excavation blasting is conducted at least 

400 m below the surface, vibration impacts are likely to be minimal (which is also consistent with 

the existing Metropolitan Colliery excavation blasting practices and experience). 

12.7 Road Traffic Noise Impact Assessment 

The existing site access and coal haulage routes remain unaltered by the Project and mine 

generated employee and materials traffic along these public roads are not increased significantly 

by the Project. Any Project related traffic noise impacts are therefore likely to be acceptable. 

On Lawrence Hargrave Drive, the maximum increase arising from the additional Project related 

traffic flow is only 0.4% during the construction and operation morning peak hour. The 

anticipated 0.4% increase in vehicle movements corresponds to a negligible (

greater). The damage risk criterion of 5 mm/s for residential dwellings is unlikely to be exceeded 

by train movements on the South Coast rail network at the nearest residential dwellings. 

As the Project would not result in significant increases in the total number of heavy vehicle 

movements on the public road network or total rail movements on the South Coast rail network, 

the existing road vibration effects of heavy vehicle movements on the public road network and rail 

vibration effects of trains on the South Coast rail network would be generally unchanged by the 

Project. 

12.10 Conclusion 

In summary, the Project noise impact assessment indicates: 

• The existing major surface facilities of the Metropolitan Colliery are a significant source of 

existing industrial noise. The Metropolitan Colliery has been operating in this location for well 

over 100 years and is located in close proximity to suburban areas in Helensburgh. 

• The Project, in extending the life of the Metropolitan Colliery by approximately 25 years, 

provides an opportunity to improve noise performance by incorporating noise management 

improvements in the CHPP and other major surface facilities upgrades. HCPL has 

committed to include a range of noise reduction and operational noise controls in the Project, 

to reduce noise emissions where practicable. 

• The modelling of existing and Project noise emissions indicates that no privately owned 

residences would experience an increase in operational noise as a result of the development 

of the Project. At the majority of private residences that are located in close proximity to the 

Metropolitan Colliery surface facilities area, the Project is predicted to provide significant 

operational noise reductions in comparison to the existing noise emissions of the 

Metropolitan Colliery. Operational noise levels at receivers near the Project boundary to the 

north are generally predicted to remain unchanged by the Project (or be slightly reduced) due 

to the contribution of train loading activities which are in close proximity and dominate noise 

emissions at these locations. 

• No significant increases in existing road or rail transport noise or vibration are predicted with 

the implementation of the Project. 

• PRPs under the Metropolitan Colliery EPL provide an effective mechanism for progressive 

improvement of site noise performance. While this noise impact assessment indicates 

significant noise reduction would occur as a result of the development of the Project, it is 

recommended that the PRP process is continued to provide a mechanism to identify and 

implement further noise management or improvement measures that may be practicable 

over the life of the Project.

USE OF RURAL, SUBURBAN, URBAN AND URBAN/INDUSTRIAL INTERFACE NOISE AMENITY ZONES 

The NSW Industrial Noise Policy (INP 2000) prescribes detailed calculation routines for establishing 

“project specific” LAeq(period) amenity (ie non-transport related) criteria for a development at potentially 

affected receivers. The INP’s noise amenity criteria are dependent on establishing the appropriate noise 

amenity zone (ie rural, suburban, urban etc) and the existing industrial noise level which are then used in 

conjunction with the Table 2.1 and Table 2.2 of the INP respectively. 

Section 2.2.1 of the INP, Notes to Support the Noise Level Tables, states: 

Rural - means an area with an acoustical environment that is dominated by natural sounds, having 

little or no road traffic. Such areas may include: 

- an agricultural area, except those used for intensive agricultural activities 

- a rural recreational area such as resort areas 

- a wilderness area or national park 

- an area generally characterised by low background noise levels (except in the immediate vicinity of 

industrial noise sources). 

This area may be located in either a rural, rural-residential, environment protection zone or 

scenic protection zone, as defined on a council zoning map (Local Environmental Plan (LEP) or 

other planning instrument). 

Suburban - an area that has local traffic with characteristically intermittent traffic flows or with some 

limited commerce or industry. This area often has the following characteristics: 

- decreasing noise levels in the evening period (1800-2200); and/or 

- evening ambient noise levels defined by the natural environment and infrequent human activity. 

This area may be located in either a rural, rural-residential or residential zone, as defined on an LEP or 

other planning instrument. 

Urban - an area with an acoustical environment that: 

- is dominated by ‘urban hum’ or industrial source noise 

- has through traffic with characteristically heavy and continuous traffic flows during peak periods 

- is near commercial districts or industrial districts 

- has any combination of the above, 

where ‘urban hum’ means the aggregate sound of many unidentifiable, mostly traffic-related sound 

sources. 

The INP’s Application Notes dated July 2006 supersedes the INP’s Section 2.2.1 with respect the 

application of the Urban Industrial Interface and states: 

Urban/Industrial Interface - this area may be located in either a rural, rural-residential or residential 

zone as defined on an LEP or other planning instrument, and also includes mixed land-use zones 

such as mixed commercial and residential uses. 

The urban/industrial interface category in the INP recognises that the availability of noise mitigation 

measures might be limited for existing premises where residences are close to existing industries. 

The urban/industrial interface amenity category applies only for existing situations (that is, an existing 

receiver near an existing industry) and only for those receivers in the immediate area surrounding the 

existing industry, that is, the region that extends from the boundary of the existing industry to the 

point where the noise level of the existing industry (measured at its boundary) has fallen by 5 decibels. 

For new developments of a limited nature (such as an extension to existing process or plant or when 

replacing part of an existing process or plant with new technology) on existing sites (where the 

urban/industrial amenity category applies) then the urban/industrial amenity category is the 

appropriate amenity category for the new development.

Noise coming from surface plant belt is 

keeping him awake and causing him stress. 

He sleeps with ear plugs and ear muffs to 

block the sound. 

Mr Lai also advised that he had previously 

considered acoustic screening of house but 

did not want to live in a prison. 

Discussed with Mr Lai. Advised that we are in 

process of making improvements to 

Washplant to reduce noise levels and that I 

would inform him of progress. Consider that 

subject to success of PRP11 that double 

glazing windows facing mine may be 

warranted, or installation of acoustic 

screening along boundary. 

To review potential double glazing or 

screening as PRP11 progresses. 

Discussed with Mr Lai that improvements 

were currently underway to close off the open 

side of the crusher building which will be 

completed in the next 2 weeks as well as 

installation of mufflers on the washery vacuum 

pumps which will reduce the constant 

background noise level. I informed Mr Lai that 

once the works were complete, that a noise 

expert would return to conduct another noise 

survey at the rear of his property. 

Washery was operating and in process of 

shutting down. There was a cracked trash 

screen deck on CV04, which would become 

noisy (rattling) when coal was not running on 

the belt. This appears to be the most probable 

cause. The cracked deck was repaired on 

Saturday 3/9/05. 

Sound did come from dozer, which has to 

refuel overnight when fuel truck does not 

service machines. Noise came from when 

dozer travelling over concreted pavement. 

Requested to SADA that on days when the 

fuel truck does not service machines that the 

dozer refuel late afternoon or early evening so 

that it has sufficient fuel to operate all night 

without having to refuel. 

Tried to contact Mr Lai on two 

occasions. Spoke with Mr Lai’s wife and 

son a separate occasions and explained 

that the first step towards noise 

reduction would be closing in (sheeting) 

of the crusher building. Offered to 

provide diagrams, offer declined.

Resident of Oxley Pl for many years hears 

humming noise from colliery that seems to 

have increased over the last few years. Have 

noticed improvements as well particularly with 

the stone chute and reversing alarms but the 

humming noise is getting worse. 

Inspected residence with Mr Lai and heard 

noise from the back of his property, which 

back onto the mine. Noise appears to come 

from either the washery (likely) or MD1 

drivehead. Gave him the undertaking that it 

would be investigated and that I would 

feedback as information was available. Will 

contact DNA to carry out some noise 

measurements.

BACKGROUND NOISE MONITORING RESULTS - DECEMBER 2006 

Overview of Methodology 

A noise monitoring programme was commenced in December 2006 to quantify background noise levels 

(ie all noise sources) and to estimate industrial noise only (ie. in the absence of transport, natural and 

domestic noise). Four unattended noise loggers were positioned at representative residential localities 

adjacent to the Metropolitan Colliery site commencing Monday 29 December 2006 for a period of 

10 days. 

In order to supplement the unattended logger measurements and to assist in identifying the character and 

duration of the noise sources, operator-attended daytime, evening and night-time surveys were also 

conducted at all four logging locations. 

The background noise monitoring programme was implemented in accordance with AS 1055-1997 

“Acoustics-Description and Measurement of Environmental Noise” and the NSW Industrial Noise Policy 

(INP) 2000. 

3.2 Instrumentation and Measurement Parameters 

Unattended Monitoring and Operator-Attended Surveys 

All acoustic instrumentation employed throughout the noise monitoring programme has been designed to 

comply with the requirements of AS 1259.2-1990, “Sound Level Meters” and carries current National 

Association of Testing Authorities (NATA) or manufacturer calibration certificates. 

A description of instrumentation, designated type and serial numbers is shown in Table 1. 

Table 1 

Acoustic and Meteorological Instrumentation Schedule

F19 19 Old Farm Road, Helensburgh Front of property n/a 193410 

n/a Mine Managers Residence n/a Front of property TBA 

All instrumentation was programmed to record continuously the noise exceedance levels in 15 minute 

intervals including the LAmax, LA1, LA10, LA50, LA90, LA99, LAmin and the LAeq. 

Instrument calibration was conducted before and after each measurement survey, with the variation in 

calibrated levels not exceeding ±0.5 dBA. 

Weather Station 

Local meteorological data was obtained from a portable Automatic Weather Station located at the Mine 

Managers Residence at the eastern end of the Colliery site. The AWS recorded wind speed and direction, 

air temperature, relative humidity and rainfall in 15 minute intervals. 

3.3 Unattended Background Noise Monitoring Results 

The unattended background noise logger data from each monitoring location, together with the on-site 

weather conditions were analysed on a daily basis. 

The statistical noise exceedance levels (LAN) are the levels exceeded for N% of the interval period. The 

LA90 represents the level exceeded for 90% of the interval period and is referred to as the average 

minimum or background noise level. The LA10 is the level exceeded for 10% of the time and is usually 

referred to as the average maximum noise level. The LAeq is the equivalent continuous sound pressure 

level and represents the steady sound level which is equal in energy to the fluctuating level over the 

interval period. 



Report 10-5055-R1 

Page 2 of 4 


Prior to further analysis, the background noise data from each location which correlated with periods of 

unstable weather (eg rainfall greater than 0.5 mm or wind speed greater than 5 m/s) were discarded. The 

acceptable background noise data was then processed in accordance with the INP “Appendix B - 

Applying the Background Noise Policy” to derive the Monday to Sunday background noise levels 

presented in Table 2.

TRAFFIC NOISE MONITORING RESULTS - MARCH 2007 

Overview of Methodology 

A noise monitoring programme was commenced in March 2007 to quantify ambient noise levels (ie all 

noise sources) and to estimate traffic noise only (ie all vehicles). Three unattended noise loggers were 

positioned at representative residential localities adjacent to the Metropolitan Colliery off-site haulage 

routes commencing Wednesday 21 March 2007 for a period of 8 days. 

In order to supplement the unattended logger measurements and to assist in identifying the character and 

duration of the noise sources, operator-attended daytime, evening and night-time surveys were also 

conducted at all three logging locations. 

The background noise monitoring programme was implemented in accordance with AS 1055-1997 

“Acoustics-Description and Measurement of Environmental Noise” and the NSW Environmental Criteria 

for Road Traffic Noise (ECRTN 1999). 

3.2 Instrumentation and Measurement Parameters 

Unattended Monitoring and Operator-Attended Surveys 

All acoustic instrumentation employed throughout the noise monitoring programme has been designed to 

comply with the requirements of AS 1259.2-1990, “Sound Level Meters” and carries current National 

Association of Testing Authorities (NATA) or manufacturer calibration certificates. 

A description of instrumentation, designated type and serial numbers is shown in Table 1. 

Table 1 

Acoustic and Meteorological Instrumentation Schedule 

ID Location Noise Logger Off-set Distance Serial Number 

L171 171 Lawrence Hargrave Drive, Helensburgh Near front boundary South 12 m 16-004-033 

P170 170 Parkes Street, Helensburgh Near front boundary North 15 m 16-004-034 

P83 83 Parkes Street, Helensburgh Adjacent front facade South 13 m 16-004-038 

All instrumentation was programmed to record continuously the noise exceedance levels in 15 minute 

intervals including the LAmax, LA1, LA10, LA50, LA90, LA99, LAmin and the LAeq. 

Instrument calibration was conducted before and after each measurement survey, with the variation in 

calibrated levels not exceeding ±0.5 dBA. 

Weather Station and Traffic Counters 

Local meteorological data was obtained from a portable Automatic Weather Station located at the Mine 

Managers Residence at the eastern end of the Colliery site. The AWS recorded wind speed and direction, 

air temperature, relative humidity and rainfall in 15 minute intervals. 

3.3 Unattended Background Noise Monitoring Results 

The unattended ambient noise logger data from each monitoring location, together with the on-site 

weather conditions were analysed on a daily basis. 

The statistical noise exceedance levels (LAN) are the levels exceeded for N% of the interval period. The 

LA90 represents the level exceeded for 90% of the interval period and is referred to as the average 

minimum or background noise level. The LA10 is the level exceeded for 10% of the time and is usually 

referred to as the average maximum noise level. The LAeq is the equivalent continuous sound pressure 

level and represents the steady sound level which is equal in energy to the fluctuating level over the 

interval period.

Page 2 of 2 

TRAFFIC NOISE MONITORING RESULTS - MARCH 2007 

Prior to further analysis, the ambient noise data from each location which correlated with periods of 

unstable weather (eg rainfall greater than 0.5 mm or wind speed greater than 5 m/s) were discarded. The 

acceptable ambient noise data was then processed in accordance with the ECRTN to derive the Monday 

to Sunday ambient noise levels presented in Table 2.

LAeq(1hour) 

Operator-attended noise surveys of 15 minutes duration were conducted with a precision integrating 

sound level meter in order to qualify the results obtained with the unattended noise loggers. During the 

attended noise surveys, the operator identified the character and duration of acoustically significant 

ambient noise sources. Wherever applicable, the operator described local traffic conditions and made a 

qualitative assessment of the prevailing weather conditions. 

The daytime operator-attended noise survey results are presented below:

NSW DECC CONSTRUCTION SITE NOISE GUIDELINE 

CHAPTER 171 

NOISE CONTROL GUIDELINE CONSTRUCTION SITE NOISE 

Where there is likelihood of annoyance due to noise from construction sites, conditions such as the 

following may be specified in a development consent or building application. 

This applies particularly to non-scheduled premises such as commercial buildings where a long 

construction time is not likely. 

The criteria may not be applicable to long-term construction such as coal mines which may take several 

years. 

Variations should be made according to local conditions. 

Level Restrictions 

i 

Construction period of 4 weeks and under. 

The LA10 level measured over a period of not less than 15 minutes when the construction site is in 

operation must not exceed the background level by more than 20 dBA. 

ii 

Construction period greater than 4 weeks and not exceeding 26 weeks. 

The LA10 level measured over a period of not less than 15 minutes when the construction site is in 

operation must not exceed the background level by more than 10 dBA. 

Time Restrictions 

Monday to Friday 7.00 am to 6.00 pm. 

Saturday 7.00 am to 1.00 pm if inaudible on residential premises, otherwise 8.00 am to 1.00 pm. 

No construction work to take place on Sunday or Public Holidays. 

Silencing 

All possible steps should be taken to silence construction site equipment. It is particularly important that 

silenced equipment should be used on road or rail works where 24 hour operation is necessary.

VIBRATION DAMAGE AND ANNOYANCE RISK CRITERIA 

Vibration - Building Structures 

The German Standard DIN 4150-3:1999 “Structural Vibration Part 3: Effects of vibration in structures” 

provides the most recently updated criteria against which the likelihood of building damage from ground 

vibration can be assessed. The recommended limits for short and long-term vibration to ensure minimal 

risk of damage are presented numerically in Table 1.

purposes, industrial buildings and 

buildings of similar design 

2 Dwellings and buildings of similar 5 5 to 15 15 to 20 15 mm/s 5 mm/s 

design and/or occupancy 

3 Structures that, because of their 

3 3 to 8 8 to 10 8 mm/s 2.5 mm/s 

particular sensitivity to vibration, cannot 

be classified under Lines 1 and 2 and 

are of great intrinsic value (eg buildings 

under preservation order) 

Note 1: At frequencies above 100 Hz, the values given in this column may be used as the minimum values. 

Vibration - Buried Pipework 

DIN 4150-3:1999 also provides guideline values for evaluating the effect of vibration on buried pipework. 

The values are based on the assumption that pipes have been manufactured and laid using current 

technology. Additional considerations may be required at junctions. The recommended limits for short 

and long-term vibration to ensure minimal risk of damage are presented numerically in Table 2. 

Table 2 Guideline Values for Short and Long-term Vibration Effects on Buried Pipes (mm/s)

concrete, metal (with or without flange) 

Masonry, plastic 50 mm/s 25 mm/s 

Note 1: Mounting equipment directly onto pipes may not be possible. If the vibration source is not immediately next to the 

pipework, measurements can be made on the ground surface to obtain a conservative estimate. 

Vibration - Human Comfort 

NSW DECC has released “Assessing Vibration: A Technical Guideline” dated February 2006 which 

provides guideline building vibration levels associated with a low probability of annoyance to occupants 

arising from continuous (or impulsive) vibration sources. The DECC’s guideline is based on the 

information set out in British Standard 6472-1992 “Evaluation of Human Exposure to Vibration in 

Buildings (1 Hz to 80 Hz)” which defines levels of building vibration associated with a “low probability of 

adverse comment” from occupants. The applicable levels for continuous activities are shown in Table 3.
