The Mid Wales (Powys) Conjoined Public Inquiry into 5 Windfarm Applications and a 132kV Overhead Electric Line Connection Session 4 Matters in Common/Cumulative Effects Proofs of Evidence on Transport Matters made jointly by Cyngor Cymuned Carreghofa Community Council (Inquiry Reference OBJ-001) Cyngor Cymuned Llandysilio Community Council (Inquiry Reference OBJ-849) Cyngor Cymuned Llandrinio and Arddleen Community Council (Inquiry Reference OBJ-157) page 1 of 27 1 Introduction 1.1 The three Community Councils presenting this evidence, Carreghofa, Llandysilio and Llandrinio & Arddleen, all lie along the A483, the principle trunk road to be used for conveying windfarm traffic, particularly the “abnormal loads” of turbine parts. In order to avoid repetition of evidence to the Inquiry, the Councils have agreed to present their evidence jointly. 1.2 The Councils are deeply concerned with the impact which the transportation of windfarm components, together with additional HGV and other traffic, will have on our local communities. While we have confined our evidence to the 158 turbines that are now the subject of this Inquiry, we are mindful of the fact that a total of over 800 turbines, either granted, applied for or pending, have been proposed for mid-Wales. 1.3 While we are three Welsh Community Councils, we cannot limit our evidence solely to the Welsh part of the A483, from Llanymynech southwards. We need to look at what happens on the English side of the border before the southbound windfarm components reach us. 1.4 The extent of the A483 that will be covered in the evidence is from Oswestry to the north and Welshpool to the south, specifically between the junction with the A5 (Mile End roundabout) and the junction with the A458 (Buttington roundabout) to the south with particular emphasis on the section between Llynclys crossroads and the Four Crosses roundabout. 1.5 Appendix A shows a map of the route from the Mile End roundabout to the Buttington roundabout and Appendices A1 to A8 show photographs of the major junctions along the route. page 2 of 27 2 The schemes that are the subject of this Inquiry Electricity Act 1989 (Sections 36, 37, 62(3) & Schedule 8) Town and Country Planning Act 1990 (Section 90) Application by Vattenfall dated 30 November 2007 for consent to construct and operate a 59.5MW wind turbine generating station in Powys, Mid Wales (“Llanbadarn Fynydd”) Application by Fferm Wynt Llaithddu Cyf dated 7 May 2008 for consent to construct and operate a 66.7MW wind turbine generating station in Powys, Mid Wales (“Llaithddu”) Application by Celtpower Limited dated 9 May 2008 for consent to construct and operate a 126MW wind turbine generating station in Powys, Mid Wales (“Llandinam”) Application by RES UK & Ireland Limited dated 27 March 2009 for consent to construct and operate a 100MW wind turbine generating station in Powys, Mid Wales (“Llanbrynmair”) Application by RWE NPower Renewables Limited dated 11 December 2008 for consent to construct and operate a 130-250MW wind turbine generating station in Powys, Mid Wales (“Carnedd Wen”) page 3 of 27 3 History 3.1 All three Councils are attendees of the Montgomeryshire Local Council Forum which has considered all aspects of the applications and has been a key objector to all windfarm development in Montgomeryshire. 3.2 Each of the three Councils has also, in their own right, objected to windfarm development in Montgomeryshire. 3.3 Llandysilio Community Council completed a survey of residents in January 2013; 84% of respondents said they were worried about the large lorry convoys coming through the community. 3.4 Llandrinio and Arddleen Community Council completed a survey of residents in January 2013; 88% of respondents said they were worried about the large lorry convoys coming through the community. 3.5 Carreghofa Community Council completed a survey of residents in January 2013; 97.85% of respondents said they had not been consulted regarding transport movements through Llanymynech. 3.6 Appendices B1 to B3 show the full results of each of the Community Council’s surveys. page 4 of 27 4 Abnormal Indivisible Loads 4.1 The Strategic Traffic Management Plan (sTMP) has been developed by Grontmij and approved by Welsh Assembly Government, Powys County Council, Shropshire Council, Police, Highways Agency and Wind Farm Developers who are signatories to the Plan. 4.2 South Wales ports have been discounted due to distance from the sites which is supported by the Highways Agency Water Preferred Policy document, paragraph 3.6.1 (Appendix B) and the Welsh Assembly Government. On this basis we understand that routing for all AILs for the five windfarm proposals covered by this Inquiry, a total of 158 turbines, will be from Ellesmere Port via Wrexham, Oswestry and Welshpool along the A483. 4.3 We have studied the sTMP, section 2: Ellesmere Port to Welshpool, (the Plan) submitted by Renewable UK Cymru and consider that the Plan seriously understates the anticipated delay times which will be experienced by our residents, as well as through traffic, by abnormal indivisible loads required for the construction of the windfarms. 4.4 The A483 between the junction with the A5 (Mile End roundabout) to the north and the junction with the A458 (Buttington roundabout) to the south is already a busy single carriageway road. The Department for Transport’s Annual Average Daily Flow (AADF) figures for 2012, the latest available on their website, show that for the 13 miles of the A483 between the Mile End and Buttington roundabouts: ñ the annual average number of all motor vehicles is 10,257 per day ñ the annual average number of all HGVs is 960 per day, representing 9.63% of the total See Appendix C for a summary of this data. 4.5 There are 8 major junctions along this route: A5/A483 (Mile End roundabout), Oswestry B5069 (Morda) A495/B4396 (Llynclys crossroads) B4398 (Llanymynech crossroads) B4393 (Four Crosses roundabout) B4393 (Maerdy Bridge) B4392 (Arddleen) A483/A485 (Buttington roundabout), Welshpool In addition we have counted a further 25 minor roads and 102 private drives between Llynclys and Four Crosses alone. These provide access principally to individual domestic properties as well as to farms and small businesses. page 5 of 27 4.6 Using the figures agreed between Montgomeryshire Local Council Forum and windfarm developers, each turbine will require nine AILs. According to the sTMP Overview Report, paragraph 5.2.3, “At present, the police are prepared to escort convoys of up to two vehicles. It is therefore proposed to trial convoys of only two abnormal load vehicles initially, with a view to increasing the convoy size to three abnormal load vehicles if the delivery system is found to work well”. As an increase from two to three loads per convoy is currently hypothetical, we are working on a total of 1422 AILs in 711 convoys from Ellesmere Port. 4.7 According to the sTMP Overview Report, paragraph 7.1: ñ initially convoys are planned to move through Newtown before 7am on a weekday ñ no more than one convoy per day will be moved through Newtown between 7am and 7pm on a weekday ñ convoys are planned to move through Welshpool between the morning and lunchtime peaks on a weekday ñ no more than one convoy per day will be moved through Welshpool between 7am and 7pm on a weekday ñ convoys may also be moved through Welshpool before 7am and through Welshpool and Newtown at weekends or after 7pm on a weekday However in paragraph 7.2.3: ñ convoys travelling on via Welshpool will depart the Mile End layover area at around 9.30am to pass through Welshpool before the afternoon peak period ñ convoys travelling on via Newtown will depart Ellesmere Port at around 9.30am to stop at the Abermule layover area before lunchtime Conversely, in the notes associated with Table 2-3 of the Plan, note 1 states “Convoy assumed to depart Mile End layover area at approximately 9.30am”. This implies application to all convoys regardless of their subsequent destination. 4.8 While the information outlined in 4.7 above is contradictory in some of its detail, it would appear that convoys are planned to travel between the Mile End roundabout and the Buttington roundabout during the morning to lunchtime period on a weekday. We are unclear whether the possible weekend convoys through Welshpool and Newtown would entail weekend convoy movements between Oswestry and Welshpool which would critically impede other traffic both along and across the A485 and surrounding roads. 4.9 The sTMP Overview Report, paragraph 7.2.2 states: “More than one convoy may be moved during any one day between Ellesmere Port and the layover areas if appropriate.” Without knowing which layover areas are being referred to, we are unclear whether this will mean more than one convoy per day is intended to travel between Oswestry and Welshpool. page 6 of 27 4.10 In the notes associated with Table 2-3 of the Plan, note 2 states “Average speed of convoy assumed to be 30mph”. 4.11 All of the loads are classified as abnormal loads under the Road Vehicles (Authorisation of Special Types) (General) Order 2003 (STGO). STGO paragraphs 28(2) defines a load of exceptional width as exceeding 4.3 metres and paragraph 30(2) sets a speed limit for these wide loads of 30mph on roads other than motorways or dual carriageways. 4.12 STGO defines three categories of abnormal loads: Category 1 up to 50 tonnes gross weight, maximum speed on roads other than motorways or dual carriageways 40mph Category 2 from 50 to 80 tonnes gross weight, maximum speed on roads other than motorways or dual carriageways 30mph Category 3 from 80 to 150 tonnes gross weight, maximum speed on roads other than motorways or dual carriageways 30mph While some loads may fall within Category 1, convoys will be mixed and can only go as fast as the speed limit for Category 2 and 3 vehicles.
