2.2 Jetty Development 2.2.1 The jetty development is needed early to provide a means for delivery of bulk construction materials (principally stone, sand and cement) to the construction site at Hinkley Point. They are necessary as Preliminary Works to the Hinkley Point C Project to speed up the construction programme so that the new power station can be operational by 2018. This is in line with Government policy that encourages early development of new nuclear build to assist in meeting the UK’s carbon reduction targets (to help mitigate climate change) and improve the diversity and security of our electricity supplies. 2.2.2 In addition, early construction of the temporary jetty would mean it would be available to serve the whole of the construction phase for Hinkley Point C; thus minimising HGV construction traffic on local roads. 2.3 Site Preparation Works 2.3.1 The proposed site preparation works involve the following activities: site clearance (including erection of fencing, vegetation removal, demolition of existing structures, and creation of alternative footpaths); earthworks (including soil stripping and storage, site levelling, soil screening / storage for subsequent re-use on site); provision of earth retaining structures; deep excavations; provision and relocation of drainage infrastructure (including culverts, outfalls, balancing ponds); the provision and operation of plant and machinery (including plant for concrete batching); site establishment works (including the provision of construction compounds and associated (including layover) facilities, car parks, haulage roads, site access points and roundabouts, and laying, replacement and/or diversion of utilities); and other associated works. In the event that Hinkley Point C is not consented, all structures would be removed and the site reinstated. Collectively these works are necessary to enable the earliest possible completion of construction of Hinkley Point C following the grant of the DCO. 2.3.2 Prior to commencing the site preparation works and, where relevant, subject to obtaining separate planning permission, a small package of enabling works is also to be initiated in 2010 to facilitate the site preparation works. These works would include remediation works to remove known areas of asbestos contamination within an existing spoil mound on site and in other areas of made ground located within the eastern part of the application site (see Section 8.8). 3 CONSENTING AND EIA REQUIREMENTS 3.1.1 As identified above, EDF Energy is seeking a HEO to authorise the jetty development and FEPA licences to authorise discrete aspects of the jetty development’s construction. Both of the consent application procedures include provisions for EIA in accordance with the requirements of European Community Directive 85/337/EEC (as amended) On the Assessment of the Effects of Certain Public and Private Projects on the Environment (herein referred to as the ‘EIA Directive’). In relation to the HEO, the EIA Directive is transposed into national law by the Harbour Works (Environmental Impact Assessment) Regulations 1999 (as amended in 2000 and 2009). In relation to FEPA licences, the EIA Directive is transposed into national law by the Marine Works (Environmental Impact Assessment) Regulations 2007. 3.1.2 Through a ‘screening’ process, the MMO has confirmed that the jetty development is subject to EIA under the provisions of the EIA Directive and both of the aforementioned Regulations because it, or elements of it, would either qualify as facilitating and relating to Hinkley Point C Preliminary Works Non Technical Summary Temporary Jetty Development 2 November 2010
a nuclear power station development, or qualify in its own right constitute a port development. Accordingly, the jetty development is subject to EIA. 3.1.3 Since the jetty development would be situated within and adjacent to a number of internationally important nature conservation sites (i.e. the Severn Estuary Special Area of Conservation (SAC), Special Protection Area (SPA) and Ramsar site), it would need to comply with the measures set out in Council Directive (1992/43/EC) On the conservation of natural habitats and wild flora and fauna (herein referred to as the ‘Habitats Directive’), which is transposed into UK law through the Conservation of Habitats and Species Regulations 2010. 3.1.4 In addition, the jetty development includes a number of activities that would require separate legal consents from a number of different regulatory bodies, potentially including land drainage consents, discharge consents, waste management exemptions / licences, and protected species licences. Prior to commencement of these activities, EDF Energy will ensure that it has secured the necessary consents and that any relevant works are undertaken in full compliance with legal requirements and best practice. 4 EDF ENERGY AND NUCLEAR POWER 4.1.1 Électricité de France (EDF) is one of the world’s largest energy companies and the world’s largest operator of nuclear power plants, with 58 operational plants in France and a further one under construction at Flamanville in Normandy. EDF has a strong safety track record in the operation of nuclear power stations and safety is at the heart of the design and operating procedures for all its nuclear plants. Within the UK, EDF operates via its UK subsidiary – EDF Energy – and currently owns and operates eight nuclear power stations, including Sizewell B in Suffolk. 4.1.2 EDF Energy has indicated publicly for over three years that it would be interested in investing in a new generation of nuclear plants in the UK and that it is confident that new plants can be built and run safely and economically, without subsidy. 5 PROJECT DESCRIPTION 5.1 The Application Site 5.1.1 This section describes the jetty development and the characteristics of the application site and surrounding area that it could affect. The application site (see Figure 1) is located on the northern coastline of West Somerset, 25km to the east of Minehead and 12km to the north-west of Bridgwater, and falls within the parish of Stogursey. The onshore component of the application site falls within the land under the control of EDF Energy, adjacent and to the west of the existing Hinkley Point Power Station Complex. The offshore component of the application site extends into Bridgwater Bay, part of the Severn Estuary. 5.1.2 Immediately to the east of the application site are the Hinkley Point A and Hinkley Point B nuclear power stations (i.e. the Hinkley Point Power Station Complex). Hinkley Point A operated between 1965 and 2000 and is currently undergoing decommissioning by the Nuclear Decommissioning Authority (NDA). Hinkley Point B, owned by EDF Energy, has operated since 1976 and is scheduled to continue generating until at least 2016.
