Geology, Soils and Contaminated Land<br />
No sites designated for their geological interest would be affected by the proposals.<br />
No geological resources of particular significance have been identified which would<br />
be affected by the works and no significant effects are predicted.<br />
Peat is commonly found across the site ranging in depth from very shallow to more<br />
than 3m. A peat slip hazard assessment has been undertaken which indicates that<br />
hazards can be mitigated by implementation of mitigation measures in the detailed<br />
design and the risk of peat slide of the mitigated design would not be significant.<br />
No significant areas of contaminated land have been identified which could be<br />
affected by the works. An area of potentially contaminated land was identified by<br />
ERC some 100m south east of turbine MHT-114. This would be investigated prior to<br />
construction commencement and if contaminated the contractor would be required to<br />
avoid the area of contamination and ensure that all potential indirect effects were<br />
mitigated. Implementation of best management practices including good design of<br />
the works would ensure that any impacts to soils were minimised. Implementation of<br />
best management practices and the committed mitigation measures would ensure<br />
that any risk of subsidence due to the decomposition of buried peat would be avoided<br />
and the risk of peat slides minimised.<br />
The total carbon emission generated by construction of the proposals is 130,772<br />
tonnes of carbon dioxide per year (tCO2 yr -1 ). Taking into account the estimated<br />
carbon dioxide savings which would be generated by the windfarm then the overall<br />
payback time in terms of carbon dioxide emissions for the proposals is calculated to<br />
be 1.7 years.<br />
Water Quality and Drainage<br />
There would be no significant effects on hydrology,<br />
water quality and drainage provided all mitigation<br />
measures were successfully implemented. No known<br />
private water abstractions would be affected by the<br />
development and groundwater supplies would be<br />
protected by design of the works in accordance with<br />
best practice.<br />
The contractor would be required to develop and<br />
implement a Water Protection Plan as part of the site EMP to ensure proactive<br />
protection of watercourses, groundwater and potable water supplies including the two<br />
public water supply reservoirs. All design and protection measures (permanent and<br />
temporary) would be agreed with SEPA and Scottish Water in advance of<br />
construction. Flood risk would be appropriately mitigated and would not be<br />
significant.<br />
Best management practices would be implemented during construction and<br />
maintenance activities during operation to ensure there was no significant impact on<br />
water quality. There would be minor adverse effects during construction and the<br />
contractor would be required to monitor the effectiveness of all protection measures<br />
during all phases of construction. Accidental spills and leaks would be dealt with as<br />
part of the emergency response plan and all site staff would be trained on its<br />
implementation.<br />
