Camilty Wind Farm Siltbusters or equivalent device), as well as installation of splash boards at watercourse crossing points to prevent contamination from track run-off; • Chemicals, oils and hazardous materials will be stored in designated areas securely at a minimum distance of 50 m from the watercourses; • Spillage contingency kits will be provided in all site vehicles and there will be daily checks for oil and fuel leaks; • Application of best practice in relation to the removal and storage of vegetation turfs and soils to ensure effective reinstatement of vegetation wherever possible; • Application of best practice techniques of track and turbine base construction to ensure that drainage patterns and water quality within the study area are maintained; • Application of best practice to ensure materials appropriate to site geology are used in construction activities; • All habitats within 86 m distance of a turbine (which equals 50 m distance between blade tips and habitat) should be maintained in a state which offers poor foraging for bats: tree and scrub growth to be controlled and pond formation to be avoided (Entwistle et al. 2001). See Appendix 11.5 for details on how keyhole dimensions are calculated; • Timing of works to avoid periods of heavy rain when the risk of fine sediment being transported from earth works is significantly increased. Detailed method statements relating to pollution prevention and control will be presented in the HSEMS and are discussed further in Chapter 13: Hydrology, Hydrogeology and Ground Conditions. 11.7.4 Pollution incident response and drainage management measures will be prepared as a part of the HSEMS to minimise potential pollution effects. 11.7.5 A suitably experienced Environmental Clerk of Works (ECoW) will be present on site to oversee enabling works and construction, whose role will ensure works are carried out in accordance with the HSEMS to ensure compliance with international and national legislation and planning conditions. The ECoW will also review results of protected species surveys prior to commencement of works in different areas within the site. Once works are underway, the ECoW will work on site providing ecological and pollution control advice and supervision for all relevant mitigation measures. 11.7.6 While species such as red squirrel have not been identified within the site boundary, the potential remains for them to move into the site due to their highly mobile nature. As such, part of the ECoW’s duties will be to provide pre-construction and pre-felling checks for protected species. 11.7.7 Best practice measures for minimising the potential for disturbance and injury to protected species will be employed. These will include: • Covering all trenches, trial pits, excavation and pipelines to prevent animals entering these holes; • Provision of a method of escape (e.g. A plank) where such excavations cannot be closed or filled on a nightly basis; and • Vehicle speeds will be restricted across the site in order to minimise the risk of collision with animals.

Camilty Wind Farm 11.7.8 The mitigation measures outlined in Chapter 13: Hydrology, Hydrogeology and Ground Conditions for protecting watercourses and water bodies will ensure that the pre-construction quality of watercourses are maintained during and post construction. Where water crossings are to be upgraded, these will be designed to minimise any disturbance to the watercourse and geomorphological processes. The structures will not present any significant barriers to the passage of migratory fish or other fauna. Further details of the proposed water crossing designs can be found in Appendix 13.3. 11.7.9 Water quality baseline surveys and subsequent monitoring during the construction phase of the development will encompass chemical testing, daily visual inspections of waterways by the ECoW, and macro-invertebrate sampling to ensure water quality is maintained. 11.7.10 Where practicable, reinstatement of habitats will be undertaken around infrastructure. This will be carried out as the work front progresses, or as soon as is practical after the completion of the works. The methods of this will be detailed within the HSEMS. Operation Mitigation 11.7.11 The vehicle speed restrictions stipulated above should also be implemented during the operation of the proposed wind farm. 11.7.12 Vehicles coming on site will be regularly checked for oil leaks to avoid risk of pollution. Spillage kits will be available on the site. Best practice methodologies (outlined in the HSEMS) will be employed during any maintenance works to ensure the prevention of any pollution to habitats or watercourses, along with implementation of the site pollution incident response plan and drainage management plan. 11.7.13 In line with SNH accepted Natural England guidance, all habitats within 50 m of the turbines blade tips will be maintained in a state which offers poor foraging for bats. Operation Enhancement 11.7.14 A method statement for post construction monitoring for bat fatalities will be included in the site operation procedures as an enhancement (see Table 11.23) in order to increase understanding of bats and turbines related issues. Decommissioning Mitigation 11.7.15 Best practice measures, as described in the construction stage, will be followed. New guidance available at the decommissioning phase will be adopted if appropriate. 11.8 Assessment of Residual Effects 11.8.1 The mitigation measures described above are expected to reduce residual effects for all VERs to acceptable levels (‘slight’ or ‘negligible’ levels of effect) in the short and long term. These are detailed for each VER below in Table 11.25. 11.8.2 Providing the mitigation measures proposed are fully implemented, it is predicted there will be no long-term significant negative effects on any of the locally occurring habitats or species of importance.
