Forthbank Wind Energy Development
practice measures for minimising potential effects on these species, particularly otter, will be
necessary as described by SNH 34 . These include measures such as;
• covering all trenches, trial pits, excavations and pipelines to prevent animals
entering these holes;
• provision of a method of escape (e.g. a plank) where such excavations cannot be
closed or filled on a nightly basis;
• no construction works to be conducted at night time hours.
11.6.24 Vehicle speeds will be restricted to 20mph across the site in order to minimise the risk of
collision with animals. This should be reduced to 15mph within 25m either side of the mammal
path which is likely to be used by otters and which crosses the site access track. This is not
predicted to be problematic as wind farm site vehicle speeds are typically regulated.
11.6.25 A pollution incident response plan will be prepared to minimise potential pollution effects.
11.6.26 Micro-siting of turbines will ensure a separation of at least 50m between turbine blades and
trees, following the methodology described by Natural England 4 , taking into account the
predicted growth height over the project lifespan, and thus minimising potential for bat mortality
to a non-significant level.
11.6.27 An Ecological Clerk of Works (ECoW) will be present on site to oversee enabling works and
construction. They will be a suitably experienced individual, approved by SNH and
Clackmannanshire Council, whose role will ensure works are carried out in accordance with all
relevant Construction Method Statements, the Environmental Protection Plan and to ensure
compliance with international and national legislation. They will also review results of
protected species searches prior to commencement of works in different areas within the site
and contribute to all relevant Construction Method Statements. Once works are underway,
their role will be to work on site providing ecological and pollution control advice and
supervision for all relevant mitigation measures.
11.6.28 The mitigation measures outlined in Chapter 13. Hydrology, Geology and Hydrogeology, for
protecting watercourses and waterbodies will ensure that the pre-construction quality of
freshwater courses are maintained during and post construction.
Operation Phase Measures
11.6.29 The vehicle speed restrictions stipulated above should also be implemented during the
operation of the proposed wind energy development.
11.6.30 Vehicles coming on site will be periodically checked for oil leaks to avoid risk of pollution.
De-commissioning Phase Measures
11.6.31 Best practice measures as described in the construction stage will be followed. New guidance
available at the de-commissioning phase would be adopted if appropriate.
