The wind farm is to be known as Llynfi Afan Renewable Energy Park (REP). 1.2 Full planning permission is sought for the following: • 15 wind turbines with a blade tip of 118m and a hub height of 78m; • a 78m high permanent wind monitoring mast, referred to as an anemometry mast or met mast; • widening of existing forestry tracks at pinch points to allow access for the vehicles delivering the wind turbine components; • upgrading and widening of existing on-site agricultural tracks and construction of new on-site access tracks, some of which would require watercourse crossings; • new access off A4107 • crane hardstandings for each turbine, referred to as crane pads; • up to four areas of stone extraction referred to as borrow pits; • underground cabling parallel to access tracks, where practical; • an electricity substation within a compound containing a control building; and • two construction compounds. 1.3 A schedule setting out the split of the proposed development across the three local planning authorities is attached at Appendix 1 to this DAS. ES figure 3.1 (attached to the DAS as Figure 1) shows the location of the application site in relation to the administrative boundaries of the three unitary authorities. 1.4 The wind turbine area development falls within NPTCBC and BCBC. No turbines fall within RCTCBC. 1.5 Following submission of the application elements of the proposed development may be subject to further, minor refinement, known as ‘micro-siting’, for a number of reasons such as to: • Reflect the findings of post-application and -permission detailed pre-construction stage ground investigations; and RPS Planning & Development 1 November 2010 Llynfi Afan Renewable Energy Park Design and Access Statement • Reflect any minor relocations required for ecological reasons (for example due to the emergence of new badger setts). 1.6 For the reasons above, the planning application seeks a planning condition to enable micro- siting of the wind turbines and other design elements to take place (within the planning application boundary shown on the planning application drawings) with or without prior consent of the local planning authority in common with other, similar planning applications. This micro-siting tolerance, within the limits of the planning application boundary shown on the planning application drawings, has been taken into account within the assessments undertaken and presented in the ES. Format of this Statement 1.7 Whilst many of the topics that are usually covered in a DAS relate to proposals for built development in urban locations and are thus not relevant to this proposal, RPS has sought to describe the proposal using similar headings. Part 1 of this Statement provides a summary introduction and background to the proposal. Part 2 of this Statement – Context – describes the site and surroundings and provides a summary of how the proposal has evolved and the consultation undertaken to date. Part 3 of the Statement – Response – describes the proposed development in terms of design principles and concepts that have been applied to the development, how issues of access to the development have been dealt with. In accordance with The Town and Country Planning (General Development Procedure) (Amendment) (Wales) Order 2009, in relation to design this statement explains the following aspects of the development: • Access – setting out both the abnormal loads access and on site access tracks • Character – including details of the site layout, turbines, cabling, control building and electrical substation, anemometry mast and borrow pits • Community Safety • Environmental Sustainability • Movement to, from and within the development Part 4 provides a summary. Background The Need to Generate Electricity from Renewable Energy 1.8 There is a range of Government legislation and guidance resulting from the Kyoto Protocol and the 2001 European Directive, which deal with renewable energy targets and the reduction of CO2 emissions. This energy policy background is detailed and appraised in the planning support statement and it is not intended to repeat that detail here. Nonetheless, the Llynfi RPS Planning & Development 2 November 2010 Llynfi Afan Renewable Energy Park Design and Access Statement Afan REP will make an important contribution towards Welsh Assembly Government installed onshore wind farm targets of 4.5 kwh/d/p by 2015/2017. Policy & Guidance 1.9 The design principles referred to in this DAS are based on national and local guidance as set out below. A more detailed assessment of the proposal against planning policy and guidance is contained in the Planning Statement, which also accompanies the application. National Policy & Guidance • The Town and Country Planning (General Development Procedure) (Amendment) (Wales) Order 2009 • The Disability Discrimination Act (DDA), 1995 • Planning Policy Wales (Edition 2 June 2010) • Technical Advice Note 8: Planning for Renewable Energy (TAN 8) (2005) • Technical Advice Note 12: Design Local Policy & Guidance • Neath Port Talbot Unitary Development Plan (adopted March 2008) • Bridgend Unitary Development Plan (adopted May 2005) • Rhondda Cynon Taff Local Plan 1991-2006 (adopted 1998) • Cynon Valley Taff Local Plan (adopted 2004) • Mid Glamorgan Replacement Structure Plan (adopted 1999) • Emerging Bridgend Local Development Plan Pre Deposit Proposals (December 2008) • Emerging Rhondda Local Development Plan Deposit Draft Local Plan (January 2009) 1.10 The status of these documents is explained in the Planning Statement submitted with the application. RPS Planning & Development 3 November 2010 Llynfi Afan Renewable Energy Park Design and Access Statement 2 Part 2: Context The Site and Site Location 2.1 The Llynfi Afan REP application site land consists predominantly of upland grassland with smaller areas of lowland grassland, marshy grassland, river valley woodland and bog and is used for upland livestock farming, namely hill-sheep farming. Steep topography, high average annual precipitation and thin soils result in quick surface run-off responses to rainfall events. There are numerous small upland watercourses crossing the site that drain either to the Afon Afan or the River Llynfi, which flow west towards Neath and south towards Bridgend, respectively 2.2 The application site is located to the east of Croeserw and to the south of Blaengwynfi and Abergwynfi. It is bounded to the north by the A4107 and the River Avan / Afon Afan. Blaengarw is located approximately 1.5km to the southeast, with Pontycymer a further 1km southwards down the Cwm Garw valley. There are a number of settlements in a relatively large conurbation to the south of Croeserw, including Caerau, Nantyffyllon, Maesteg and Cwmfelin, which follow the Llynfi valley southwards. 2.3 The forestry track to the north of the wind turbine development area is proposed as the abnormal loads access route for the development. The track is currently used for access to the conifer plantations and is managed by the Forestry Commission. The route is shown on ES Figure 5.3 and much of the route follows the boundary between RCTCBC and NPTCBC. 2.4 The wind turbine development area is mainly in NPTCBC although the southern area is in BCBC. The abnormal load across route is within RCTCBC and NPTCBC. No turbines are located in Rhondda Cynon Taff. A bridleway crosses the application site connecting north to south between Abergwynfi and Blaengarw and a footpath crosses the site east to west between Abergwynfi and the east of Croeserw. A further footpath runs from east to the south west of the site. 2.5 The southern section of the application site in BCBC lies within a Special Landscape Area (SLA). The proposed electricity substation and control building and a length of access track would lie in the SLA. 2.6 Croeserw lies at approximately 200mAOD and Blaengwynfi and Abergwynfi lie at approximately 250mAOD. The highest point on the application site is 556mAOD. Figure 2 attached shows the Site Location Including the Proposed Development. 2.7 The site boundary is not defined on the ground but is continuous with landscape that surrounds the immediate boundaries of the site.
