Stornoway Wind Farm Limited Stornoway Wind Farm Scoping Report Wood Environment & Infrastructure Solutions UK Limited – July 2018 3 © Wood Environment & Infrastructure Solutions UK Limited Executive summary Purpose of this report This scoping report has been prepared by Wood on behalf of Stornoway Wind Farm Limited (SWL). SWL is a subsidiary of Lewis Wind Power, which is a joint venture between EDF Energy Renewables (EDF ER) Holdings Ltd and Amec Project Investments Ltd in partnership with the Stornoway Trust. This report sets out the proposed scope of the Environmental Impact Assessment (EIA), the findings of which will be presented in an Environmental Impact Assessment Report (EIA Report). This purpose of this report is to serve as a formal request to the Scottish Ministers to provide a scoping opinion under Regulation 12 of the Electricity Works (Environmental Impact Assessment) (Scotland) Regulations 2017. The EIA, which this scoping request will inform, relates to a forthcoming application under section 36 of the Electricity Act 1989 (as amended) to construct and operate a wind farm on the site of the Consented Stornoway Wind Farm. Summary Findings of the Scoping Report The Proposed Development has the benefit of being able to draw on previous surveys (carried out between 2010 – 2014) and assessment work relating to the Consented Stornoway Wind Farm. Therefore, this scoping report draws on these quantitative results to identify where significant effects are likely in terms of each of the relevant environmental topics. The following environmental topic areas are proposed to be scoped into the EIA Report: Landscape and Visual; Historic Environment; Ornithology; Ecology; Fisheries; Geology, Hydrogeology and Hydrology; Traffic and Access; Noise; Socio-economics, Tourism and Recreation; Shadow Flicker; and Human Health; and Major Accidents and Disasters. July 2018 Doc Ref. 40001CGos012R 4 © Wood Environment & Infrastructure Solutions UK Limited July 2018 Doc Ref. 40001CGos012R 5 © Wood Environment & Infrastructure Solutions UK Limited Terminology For the purposes of this report the following terminology is used: The ‘Consented Stornoway Wind Farm’ - the 36 turbines and associated infrastructure granted consent by the Scottish Ministers in September 2012, which was subsequently amended in March 2016, and for which an extension of the commencement of the development date was granted in June 2017; The ‘Proposed Development’ - the revised wind farm subject to the 2018 EIA, which is currently anticipated to comprise approximately 33 turbines (approximately 25 turbines with a blade tip height of 187m and a rotor diameter of 164m; and around 8 turbines with a blade tip height of 155m and a rotor diameter of 135m). The Proposed Development layout is illustrated in Figure 2.2 in Appendix A; The ‘2011 ES’ - the Lewis Wind Power Stornoway Wind Farm Environmental Statement (Entec UK Ltd, June 2011); The ‘2015 ES’ - the Lewis Wind Power Stornoway Wind Farm ES supporting an Application for Variation of Consent (Lewis Wind Power, May 2015); The ‘Site’ means the site of the Consented Stornoway Wind Farm located approximately 1.5km west of the town of Stornoway, Isle of Lewis (and centred on National Grid Reference (NGR) E137149 N933373). The Site is shown on Figure 1.1 in Appendix A; The ‘Applicant’ means Stornoway Wind Farm Limited (SWL), a subsidiary of Lewis Wind Power, which is a joint venture between EDF Energy Renewables Holdings Ltd and Amec Project Investments Limited in partnership with the Stornoway Trust.
