monitoring would be implemented. The scale and scope of all excavation,<br />

monitoring and subsequent post fieldwork requirements would be agreed in<br />

consultation with relevant agencies. Provided all agreed mitigation was implemented<br />

the residual effects on the directly affected sites would not be significant.<br />

The consideration of impact on the setting of relevant sites has shown only one<br />

moderate adverse effect – site I, Ballagioch Cairn. All other sites have either minor<br />

adverse or no significant impact on setting.<br />

Noise and Vibration<br />

The completed assessment has considered the potential impacts that could occur<br />

during both the construction and operation of the proposed development.<br />

Noise predictions have been undertaken to determine potential impacts on existing<br />

local noise sensitive receptors (including the closest residential properties to the<br />

proposed development) during the operation of the proposed windfarm.<br />

Consideration has been given to the local properties that have, or do not have, a<br />

financial involvement in the proposed development. A detailed baseline noise survey<br />

was undertaken to inform the assessment of noise from the proposed development<br />

once operational. The effect of the Whitelee Windfarm and proposed extension was<br />

taken into account in the assessment.<br />

An assessment of potential construction noise was undertaken and even when<br />

adopting a series of worst case assumptions, predicted construction noise levels<br />

have been predicted to fall below a criterion applicable to rural areas, at the closest<br />

residential dwellings to the site. Notwithstanding this, a series of good practice<br />

construction noise mitigation measures would be implemented. At worst, a<br />

temporary adverse minor noise effect would arise from construction noise at local<br />

properties.<br />

Vibration and air overpressures that could be generated if blasting was required at<br />

the proposed borrow pits could be controlled to appropriate levels at residential<br />

properties. Groundborne vibration levels arising from possible blasting could also be<br />

controlled to appropriate levels at underground services with the agreed mitigation<br />

measures in place.<br />

The proposed turbine layout has been prepared following a detailed iterative design<br />

process taking into account the prevailing local noise environment and associated<br />

constraints. Assessment of the final scheme design has identified that the applicable<br />

noise level limits stated in ETSU-R-97 (prepared by the Energy Technical Support<br />

Unit for the Department for Trade and Industry) would not be exceeded with the<br />

candidate turbines used for the assessment operating in unconstrained mode. At<br />

worst, the effect would be negligible/minor (not significant) at local properties from<br />

the operation of the proposed windfarm. Plant noise levels limits have been<br />

calculated for the control of noise from the proposed transformers and the control<br />

building/substation and at worst, again, an adverse noise effect of negligible or minor<br />

level (not significant) would arise at local properties as a result of noise from<br />

proposed plant items.<br />

Air Quality<br />

No significant effects on air quality are predicted during construction, operation and<br />

decommissioning provided all mitigation measures are successfully implemented.<br />

There would be no significant direct effects on local or global air quality. There would<br />
