in the same principal with bats being „lured‟ to the ultrasound. This is a<br />

poorly understood subject with little evidence to prove either attraction or<br />

detraction theories. However, noise emitted at this frequency may interfere<br />

with the echolocation calls of bats. This has been assigned a minor<br />

negative impact there<strong>for</strong>e a slight adverse significance is predicted.<br />

Badgers<br />

7.65 It is considered that there will be minimal impacts to badger during the<br />

operation of the wind farm. Impacts such as potential increased mortality<br />

of badgers caused by maintenance vehicles using access tracks are<br />

considered to be minor negative with an impact significance of slight<br />

adverse.<br />

Otter, Water Vole and White-Clawed Crayfish<br />

7.66 The watercourses within the study area could potentially become polluted<br />

by spillage of oils and fuel during routine maintenance operations. As<br />

these species have not been assigned a Nature Conservation Value the<br />

impact magnitude and significance has not been assessed.<br />

Great Crested Newt<br />

7.67 No great crested newt were recorded within the study area, and the<br />

identified pond is considered unsuitable. As there are no ponds within<br />

500m of the study area, there are no <strong>for</strong>eseen impacts on great crested<br />

newt from the operation of the wind farm.<br />

DECOMMISSIONING<br />

Impacts<br />

7.68 The life of the wind farm planning permission will be approximately 25<br />

years including construction and decommissioning. Decommissioning<br />

after closure of the wind farm would involve removal of turbines and<br />

associated infrastructure. The exact methods of decommissioning are not<br />

known at present. The main <strong>for</strong>eseeable impacts would result from<br />

removal of the upper parts of the turbine foundations.<br />

Habitats<br />

7.69 It is envisaged that disturbance of the existing vegetation would occur,<br />

though not of the scale or severity experienced during the construction<br />

phase. Any reseeding of these areas and of the decommissioned access<br />

tracks might result in establishment of vegetation that is not native to the<br />

site. Other potential impacts include pollution incidents caused by<br />

accidental spillages of vehicle fuels and oils, hydraulic fluids, lubricants<br />

and trans<strong>for</strong>mer oils associated with the turbines. These impacts have<br />

been assessed <strong>for</strong> the construction phase of the project and are not<br />

anticipated to be any worse during decommissioning.<br />
