1.1 Overview 1.1.1 This Planning Statement has been prepared by Horizon Nuclear Power Wylfa Limited (Horizon) in support of a full planning application for Site Preparation and Clearance Proposals (the SPC Proposals) in association with the development of the Wylfa Newydd Power Station for submission to the Isle of Anglesey County Council (IACC). 1.1.2 Horizon is applying to the Secretary of State for a Development Consent Order (DCO) under the Planning Act 2008 (the PA 2008) [RD1] for powers to construct, operate and maintain the Power Station. 1.1.3 The SPC Proposals represent the initial development element of the Wylfa Newydd Project and have the potential to recognise and secure the first phase of economic and Welsh language opportunities that the Wylfa Newydd Project could deliver to the Isle of Anglesey. The SPC Proposals associated with the construction of the Power Station, have been designed to enable an efficient construction period following the grant of the DCO. 1.2 The Wylfa Newydd Project 1.2.1 Horizon is proposing to construct and operate the Wylfa Newydd Project, which comprises the Wylfa Newydd DCO Project, the Licensable Marine Activities and the Enabling Works. Each of these elements is described further below. The Licensable Marine Activities will be consented under a Marine Licence and the Wylfa Newydd DCO Project under a DCO, however there is some overlap between the two; the Marine Works (see below) will be consented under both. Wylfa Newydd DCO Project 1.2.2 The Wylfa Newydd DCO Project comprises those parts of the Wylfa Newydd Project which are to be consented by a DCO, namely: Power Station: the proposed new nuclear power station, including two UK Advanced Boiling Water Reactors (UK ABWRs) to be supplied by Hitachi- GE Nuclear Energy Ltd., supporting facilities, buildings, plant and structures, and radioactive waste, spent fuel storage buildings and apparatus to transfer electrical energy to the National Grid high voltage electricity transmission network; Other on-site development: including landscape works and planting, drainage, surface water management systems, public access works including temporary and permanent closures and diversions of public rights of way, new Power Station Access Road and internal site roads, car parking, construction works and activities including construction compounds and temporary parking areas, laydown areas, working areas and temporary works and structures, temporary construction viewing area, diversion of utilities, perimeter and construction fencing; © Horizon Nuclear Power Wylfa Limited Page 3 Planning Statement Wylfa Newydd Project Site Preparation and Clearance Marine Works comprising: - Permanent Marine Works: the Cooling Water System, Marine Off- Loading Facility (MOLF), breakwater structures, shore protection works, surface water drainage outfalls, fish recovery and return system, fish deterrent system, navigation aids and Dredging; - Temporary Marine Works: temporary
