Storage and Use of Potentially Polluting Substances
5.38 Storage of polluting substances at the site during the operational period of
the wind farm would only take place where agreed with the relevant
authorities. Generally, substances of this nature are transported in
minimum quantities on an 'as required' basis - i.e. the technicians would
only bring what they need for their day's work.
5.39 Each turbine would contain lubricating and hydraulic oils. These are
changed during regular maintenance operations. In the unlikely event of a
lubricant leak from a turbine gearbox or the hydraulic system within the
turbine nacelle, the turbine tower would itself act as a fully sealed bund
containing the spillage until it could be cleaned up.
Employment During Operational Period
5.40 It is envisaged that a senior technician would be employed on a full-time
basis to operate and maintain the Penny Hill Wind Farm. For the first few
years of operation, whilst the turbines are likely to be under warranty,
technicians from the wind turbine manufacturer would also be present on
site carrying out routine commissioning and maintenance and training
technicians who would ultimately be responsible for ongoing site
operations. In addition, specialist personnel may be contracted in to cover
some aspects of maintenance or bespoke troubleshooting/investigation
work.
DECOMMISSIONING
5.41 At the end of the wind farm‟s useful life it is proposed that the turbines,
transformers, control building, substation and compound would be
removed. The upper sections of the turbine foundations would be removed
and back filled with minimum 100-150 mm of appropriate material, with
topsoil replaced, and the area restored to arable agricultural use. Tracks
that are to be utilised for ongoing agricultural and land management
operations would be left in-situ, other tracks would be allowed to revegetate
or would be covered with soil and, again, restored to arable
agriculture. At least six months prior to the decommissioning of the site a
Decommissioning Method Statement would be prepared.
