Have the closest properties to the wind turbines been considered, in relation to the selection of relevant noise monitoring locations ?

The five main locations will include the closest properties around the site.


In relation to the noise compliance monitoring exercise, is it considered likely that the operator should be able to gather sufficient data in the six month period to enable a robust assessment to be made regarding compliance ?

Six months is a reasonable period, although it might need to be extended to enable sufficient data to be collected in some combinations of wind speed and direction.


Can The Council investigate instances of alleged statutory noise nuisance prior to compliance with the planning conditions being determined ?

We've obtained legal advice on this matter, as a direct response to the representations made by the community during the recent public meeting. The advice has identified some issues which require further clarification, and a more detailed response will follow once this clarification has been obtained.


In the event of compliance being reached, what can be done within the planning conditions for the council to require the operator to ensure that the operating parameters cannot be altered to the future ?

Condition 40 requires the operator to log wind and turbine operating parameters for the entire period of operation, and to provide data to the council on request. 

The council can therefore ask for this data for the monitoring period as a ‘baseline’ and can subsequently request it again to provide a comparative check. 


What control measures are available to both the operator and the council to deal with Amplitude Modulation (AM), how it can be monitored and assessed, is there any evidence which residents are able to collect to submit to the council to help in this assessment ?

At the moment there is no accepted method of objectively assessing AM and no specific acceptability criterion.

Reports to be issued soon by the Institute of Acoustics (IoA) will provide some guidance.

The (planning) conditions do not refer to AM – at the appeal, the council requested an AM condition, based on a ‘scheme to be agreed’, but the Inspector declined to impose it. 

Therefore if complaints about AM are received and we judge them to be justified, then we would need to consider action for statutory nuisance unless the operator undertook to investigate and take remedial action on a voluntary basis. 

It has been established that small changes to operating parameters, by changing the programming of the blade pitch control, can significantly reduce AM and therefore the operator is likely to be able to mitigate an AM problem.


How much revenue will the council receive in relation to business rates associated with the site, how is this figure derived, and is the figure based on a flat rate or turbine output ?

The amount of revenue which the council will receive from business rates is dependent on the rateable value of the installation, which has yet to be determined by the Valuation Office Agency (VOA).  Any queries concerning how this rateable value is determined should be made directly to the VOA.


Now that planning permission has been granted, is there any mechanism which allows for residents to request a variation of the conditions which are attached ?

We are still preparing a response to this question, and will provide a further update as soon as we are able to.
