Camilty Wind Farm 11.9 Cumulative Effects Potential Sources of Cumulative Effects 11.9.1 This section considers the assessment of cumulative effects on ecological receptors from the proposed wind farm in combination with effects from other proposed development projects within the surrounding area. This assessment has considered all development types with the potential to affect the VERs. 11.9.2 The search area for this assessment extends to 5 km from the proposed wind farm site for all VERs. This is considered to be sufficient in relation to the mean foraging ranges of badger and otter and the average commuting range for the bat species present on site. The assessment includes projects which are completed, under construction or approved (Figure 11.9). 11.9.3 There are three wind farms within 5 km of the site boundary which have been considered for all VERs: • Pearie Law Wind Farm (application) Located 3.6 km from the site boundary and consists of 6 turbines; • Harburnhead Wind Farm (appeal). Located 2.2 km from the site boundary with 22 turbines proposed; • Fauch Hill Wind Farm (appeal). Located 1.9 km from the site boundary with 23 turbines proposed. Potential Cumulative Effects on Designated Sites Craigengar SAC and SSSI, Cobbinshaw Moss SSS, Linhouse Valley SSSII and Cobbinshaw Water SSSI 11.9.4 The EIA for Harburnhead wind farm only considered Cobbinshaw Moss macrotope as a receptor. This includes the Cobbinshaw Moss SSSI and the whole peat mass in the area. A buffer of 130 m will be maintained between the infrastructure and the SSSI. This buffer is assessed as providing a margin of safety for the avoidance of any direct hydrological effects on the SSSI, and also minimises the risk of other minor potential effects such as dust deposition from tracks during construction. 11.9.5 The EIAs for Fauch Hill and Pearie Law did not consider the Craigengar SAC and SSSI, Cobbinshaw Moss SSSI, Linhouse Valley and Cobbinshaw Water SSSI as receptors as they are not within the same catchments. 11.9.6 It is concluded that the proposed Camilty development will not add cumulatively to the impacts on the Craigengar SAC and SSSI, Cobbinshaw Moss SSSI, Linhouse valley and Cobbinshaw Water SSSI. Potential Cumulative Effects on Habitats Coniferous Plantation Woodland 11.9.7 The EIAs for Harburnhead, Fauch Hill and Pearie law did not consider coniferous plantation woodland as a receptor. 11.9.8 It is concluded that the proposed Camilty development will not add cumulatively to the effects on this habitat within the surrounding area.

Camilty Wind Farm Semi-improved Acid Grassland 11.9.9 The EIAs for Harburnhead and Pearie Law do not consider this habitat as a receptor. 11.9.10 The construction of Fauch Hill will include the permanent loss of 1 ha of acid grassland. A further 1.2 ha will be temporarily lost during construction but will be re-instated. It was concluded that the loss of this habitat will be adverse and certain, but that it will not result in a significant effect relative to biodiversity and nature conservation. 11.9.11 It is concluded that the proposed Camilty development will not add cumulatively to the effects on this habitat within the surrounding area due to the small area of this habitat to be lost. Marshy Grassland 11.9.12 The EIA for Fauch Hill wind farm indicated the permanent loss of 2.5ha of marshy grassland. A further 1.4 ha will be temporarily lost during construction but will be re-instated. It was concluded that the loss of this habitat will be adverse but that it will not result in a significant effect relative to biodiversity and nature conservation. 11.9.13 The EIA for Pearie Law considered the proposal would have no significant effect on marshy grassland following mitigation as a result of habitat loss. 11.9.14 The EIA for Harburnhead did not consider marshy grassland as a receptor. 11.9.15 It is concluded that the proposed Camilty development will not add cumulatively to the effects on this habitat within the surrounding area. Heath and Mire 11.9.16 The EIAs for Harburnhead and Fauch Hill do not consider heaths and mires as a receptor. 11.9.17 The EIA for Pearie Law considered the proposal would have no significant effect on heaths or mires following mitigation as a result of habitat loss. 11.9.18 It is concluded that the proposed Camilty development will not add cumulatively to the effects on this habitat within the surrounding area. Watercourses 11.9.19 The EIA for Harburnhead does not consider any watercourses as ecological receptors. 11.9.20 The construction of Fauch Hill will involve the crossing of two watercourses, Crosswood Burn and Shear Burn which also run through the Camilty site. Construction of the watercourse crossings and of turbine footings, lay-down areas and sections of access track, which are located relatively close to existing watercourses could potentially result in the release of sediments associated with earthworks into the watercourses. There would also be the potential risk that oils, or fuels associated with construction plant and materials including concrete/cement could be accidentally released into watercourses. It was concluded that the construction after mitigation will not have a significant effect on the quality or nature conservation value of watercourses within the site or downstream of the site. 11.9.21 Vein Syke watercourse runs through Pearie Law wind farm, it lies in the same catchment area to the one at Camilty but drains further downstream. Vein Syke has a low ecological value as it is overgrazed and cattle poached but provides potential bat commuting habitat and links to Calderwood SSSI. It was concluded that after mitigation the construction will not have a significant effect on the quality or nature conservation value of watercourses within the site or downstream of the site.
