Review of Cabling Techniques and Environmental Effects Applicable to the Offshore Wind Farm Industry – Technical Report Section 5 describes the potential environmental impacts expected during cabling activities together with possible mitigation measures that could be used to reduce their scale of effect. Impacts are described and discussed for: ● ● ● ● ● ● ● ● ● 14 Intertidal habitats; Subtidal ecology; Natural fish resource; Commercial fisheries; Marine mammals; Ornithology; Shipping and navigation; Seascape and visual character; and Marine and coastal archaeology. Section 6 provides examples of good practice measures during cabling activities which could be adopted in conjunction with mitigation measures to minimise the magnitude and significance of effects on the local environment. Section 7 outlines the gaps in understanding and data identified as part of this project. Section 8 provides a full reference list.
2 Legislation 2.1 Introduction This section provides an overview of the key UK legislation regulating developmental activities during the construction, operation and decommissioning phases of cabling activities associated with offshore wind farm developments. 2.2 Licences and Consents A statutory consenting process exists through which offshore renewable development applications are considered in relation to UK policy aims and international obligations. The consenting process is designed to ensure that each development decision is made on the basis of a comprehensive balanced consideration of impacts, both positive and negative. The consents process in England and Wales is managed by the Department for Business, Enterprise and Regulatory Reform’s (BERR) Offshore Renewables Consents Unit (ORCU) and other statutory consenting authorities (the Department for the Environment, Food and Rural Affairs (Defra), the Department for Transport (DfT) and the National Assembly for Wales (NAW)). The Scottish Executive is responsible for administering the consents process for offshore wind farms in Scottish waters, and in Northern Ireland, the Department for Enterprise, Trade and Industry (DETI). The above organisations deal with consents received under the Electricity Act (EA), the Transport and Works Act (TWA), Food and Environment Protection Act (FEPA) and Coast Protection Act (CPA). The consents process for offshore wind farms, in England, Scotland and Wales, is explained in the DTI’s (now BERR) Strategic Planning Framework consultation paper (2002) and full guidance for the consents process is provided within DTI (now BERR) guidance notes (2004). National Planning Policy Guidelines (NPPG) 6 sets out national planning guidance for renewable energy developments in Scotland (Scottish Natural Heritage, 2004). In Northern Ireland, the DETI has produced a Strategic Energy Framework for Northern Ireland (DETI, 2004) and the Department of the Environment within the Northern Ireland Assembly has published details on planning process in Planning Policy Statement 1 – ‘General Principles’ (Department of the Environment, 1998). Under the auspices of the Electricity Works (Environmental Impact Assessment) Regulations 2000 (SI 2000/1927), applications for consent for offshore wind farms (greater than 1MW) must be accompanied by an Environmental Statement (ES), the formal presentation of the Environmental Impact Assessment process. In Scotland, this falls under the Electricity Works (Environmental Assessment (Scotland) 2000 Regulations (SI 2000/320) and in Northern Ireland, the Electricity (Northern Ireland) Order 1992 (SI 1992/231). The ES details the nature and extent of the potential impacts of each aspect of the construction, operation and eventual decommissioning of the wind farm and associated infrastructure. 15
