Through desk-based research, the subsequent assessment presents the potential impacts of construction, operation and decommissioning of the GWF project on the ornithological assemblage present, in particular species of conservation concern. 11.1.3 For the purposes of the Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009, Figures 11.5 and 11.6 taken together with this Chapter, fulfil the requirements of Regulation 5(2)(l) in relation to the effects of the proposed development on offshore ornithology. 11.2 Guidance and Consultation Legislation, policy and guidance 11.2.1 National Policy Statements (NPS) provide the primary basis on which the Infrastructure Planning Commission (IPC) is required to make its decisions. In preparing this Chapter the following NPS’s are of relevance to offshore ornithology: Overarching NPS for Energy (EN-1); and NPS for Renewable Energy Infrastructure (EN-3) 11.2.2 The specific assessment requirements for offshore ornithology, as detailed within the NPSs, are repeated in the following paragraphs. Where any part of the NPS has not been followed within this assessment, it is stated within in the ES why the requirement was not deemed relevant or has been met in another manner. 11.2.3 Generic biodiversity considerations are provided within Section 5.3 of EN-1 and re-iterated in Paragraphs 2.6.58 to 2.6.71 of NPS EN-3. The following paragraphs provide detail from NPS EN-3 (June 2011), which contains specific requirements for the assessment of impacts on offshore ornithological species. Included within the stated specific requirements are references to the relevant section of this Chapter, where the concern has been addressed. Galloper Wind Farm ES 9V3083/R01/303424/Exet Final Report Chapter 11 - Page 1 October 2011 11.2.4 In relation to offshore ornithology, Section 2.6.101 of the NPS states that: “Offshore wind farms have the potential for the following effects on ornithology: Collisions with rotating blades; Direct habitat loss; Disturbance from construction activities such as movement of construction/decommissioning vessels and piling; Displacement during the operational phase, resulting in loss of foraging/roosting area; and Impacts on bird flight lines (i.e. barrier effect) and associated energetic expenditure for commuting flights between roosting and foraging areas.” (Sections 16.6 to 16.10). 11.2.5 The assessment requirements for ornithology are set out in Paragraphs 2.6.102 to 2.6.105 states that: 11.2.6 “The scope, effort and methods required for ornithological surveys should have been discussed with the relevant statutory advisor. (Section 11.2). 11.2.7 Relevant data from operational offshore wind farms should be referred to in the applicant’s assessment. (Section 11.3). 11.2.8 It may be appropriate for assessment to include collision risk modelling for certain species of birds. Where necessary, the assessments carried out by applicants should assess collision risk using survey data collected from the site at the pre-application EIA stage. The IPC will want to be satisfied that the collision risk assessment has been conducted to a satisfactory standard having had regard to the advice from the relevant statutory advisor. (Section 11.3 and 11.7). Policy and guidance 11.2.9 The following guidance documents have also been used to inform the assessment of potential impacts on offshore ornithology: Guidance on the Assessment of Effects on the Environment and Cultural Heritage from Marine Renewable Developments.
