The DCO includes the rights to install (and keep installed), retain, use, inspect, maintain, renew, remove and relocate an underground cable in this land. 1.1.5 The 132kV Overhead Line would comprise conductors supported by double wood poles. The wood poles are generally no larger than 470mm in diameter, and would range between 11m and 16.6m in length. Taking into account that the nominal depth of the poles is 2.5m and the steel bracings and insulators add typically 2.3m to the length, the net result is that the actual conductor height above ground (at pole positions) is about 0.2m less than the pole length referred to. The average span between poles is 79m. 1.1.6 The Order Limits for the Proposed Development contain a Limit of Deviation (LoD) within which the 132kV Overhead Line would be located. The LoD provides a degree of flexibility to ensure that any environmental constraints, technical constraints or landowner requests can be accommodated. The LoD varies between 20m in areas with good ground conditions and 40m in areas with poor ground conditions. 1 Peak Ecology ORNITHOLOGY DATA REPORT 2014 / North Wales Wind Farm Connections – Overhead Line 1.1.7 The Proposed Development does not include all elements of the North Wales Wind Farms Connection Project. Those elements not included within the Proposed Development are known as the Wider Scheme and comprises: proposed works to St Asaph substation, including the development of an underground cable taking the connection point at St Asaph to the terminal point of the Proposed Development located in a field to the south of Trebanog, Groesffordd Marli (which is south of Glascoed Road, B5381). a new 132 kV electrical substation at Clocaenog Forest to act as the collector substation for four consented wind farms. ; temporary storage areas within the existing St Asaph substation and the Collector Substation at Clocaenog Forest; and diversions of existing of lower voltage overhead line crossings. 1.1.8 The Preferred Route Corridor, a 1km wide corridor, was initially selected following early consultations on five route options. Within this preferred route corridor, the Proposed Route Alignment was defined. This was a 100m wide corridor, mostly within the Preferred Route Corridor. The Final Route Alignment has now also been defined, which falls mostly within the Proposed Route Alignment, with the exception of a small number of areas. The Final Route Alignment is the centreline of Limits of Deviation; the area within which the poles can move, which is 20m in most instances. 1.1.9 It should be noted that upon commencement of surveying the Proposed Route Alignment had not been decided upon, hence some surveys were undertaken in the area outlined as the Preferred Route Corridor up until an agreed Proposed Route Alignment had been confirmed. Surveys that were undertaken in 2013 followed the survey area outlined in the Preferred Route Corridor, and then in 2014 followed the survey area outlined in the Proposed Route Alignment. 1.1.10 This Final Route Alignment runs from the upland forest area of Clocaenog in a north-easterly direction through undulating farmland for 5km, roughly following the route of the B4501. It then veers in a north-westerly direction for 2.2km before heading north (passing over the A543) to the west of Henllan. The route heads north-west to cross the River Elwy before heading north-east towards St Asaph. 1.2 Scope of works 1.2.1 This report has been prepared by Peak Ecology Ltd on behalf of Gillespies. It provides details of a series of ornithological surveys undertaken throughout the survey area, as described above (Annex 6.5.1- Figure 1). 1.2.2 Surveys were undertaken during the autumn and winter of 2012-2013 and the summer of 2013. 1.2.3 This report is presented with four Appendices and a separate document ‘Annex 6.5.1’ which contains all the site maps and ornithological maps referenced throughout. 2 Peak Ecology ORNITHOLOGY DATA REPORT 2014 / North Wales Wind Farm Connections – Overhead Line 1.3 Scope of works Consultations: Natural Resources Wales (NRW) were consulted with reference to the scope of ornithological surveys required. Desk Study: A desk study was undertaken consulting COFNOD the local biological reference centre and other consultees. Autumn/Winter Birds Surveys: A series of drive round winter bird surveys were undertaken during October 2012 – March 2013 (inclusive). Breeding Bird Survey: A three – visit breeding bird survey was undertaken with visits once a month during April – June 2012 (inclusive). Black Grouse Survey: A two visit black grouse survey was undertaken in March and May 2013. Snipe Survey: A single evening visits for snipe was undertaken during June 2013. Nightjar Survey: Two dusk survey visits were undertaken in June and July 2013. Vantage Point Surveys: A series of vantage point surveys was undertaken over the period November 2012 – September 2013. 1.4 Legislative context and conservation status 1.4.1 The European Union meets its obligations to the protection of bird species under the Bern (79/409/EEC) and Bonn conventions and under the EU Directive 2009/147/EC ‘The Birds Directive’ (the codified version of Council Directive 79/409/EEC, as amended).
