1 Inverclyde Wind Farm Environmental Statement Inverclyde Renewables LLP 4 Description of the Development Introduction Table 4.1: Drawings 4.1 This chapter provides a description of the physical characteristics of the proposed Inverclyde Wind Farm for the purposes of informing the identification and assessment of the likely potential significant environmental effects. Information is provided in accordance with the requirements of the EIA regulations. A description of the layout and land-take associated with the proposed turbines and the associated infrastructure is provided. In addition, this chapter provides a description of the typical details of the type of turbines proposed, along with typical details for turbine foundations, hardstanding, access tracks, the combined welfare, substation and control building, and other associated infrastructure.

Figure 4.7 Figure 4.8 Figure 5.1 Welfare, Substation and Control Building Elevation Typical Cable Trench Detail Construction Compound Layout 4.4 The EIA is based on the drawings listed in Table 4.1 and the description of the development set out in this chapter. 4.5 The locations of the proposed turbines and other infrastructure would be subject to micrositing. This process allows for minor changes in turbine or infrastructure location to respond to possible variations in ground conditions across the site, which would only be confirmed following detailed site investigation work carried out immediately prior to construction. This process also provides scope for further mitigation of localised potential environmental effects through avoidance of sensitive features. It is anticipated that the agreed tolerance micrositing distance of 50 m would form a condition accompanying any consent. Any repositioning would be carried out under the supervision of an ecological clerk of works. Further description of the application of micrositing is provided in Chapter 5: Construction and Environmental Management. Site Layout Turbine Layout 4.6 The proposed locations for all infrastructure including, wind turbines, tracks, welfare buildings, the substation and borrow pits, are shown on Figure 1.2. The turbine grid reference locations are listed in Table 4.2. Volume 2: Main Report Chapter 4: Description of the Development 4-1 ENVIRON

2 Inverclyde Renewables LLP Inverclyde Wind Farm Environmental Statement Table 4.2: Turbine Locations (British National Grid, OS GB 1936 Datum) Name Easting Northing Turbine Turbine Turbine Turbine Turbine Turbine Turbine Turbine Turbine Turbine Land Take 4.7 The permanent land take from the proposed Inverclyde Wind Farm would be 2.49 % of the total site area (209.8 hectares). The permanent land take would be limited to the area of the towers (supporting the turbines), the hardstanding area immediately around the towers, the substation and welfare buildings, the access tracks linking these elements and the link tracks to the core path network. 4.8 In constructing the wind farm there would be a requirement for temporary disturbance of land, to allow for, for example, temporary construction compounds and borrow pit excavation. This land would be restored following the completion of the construction works. 4.9 Table 4.3 sets out the approximate permanent and temporary land take associated with each element of the proposed Inverclyde Wind Farm, and provides an estimate of the total areas of land take.

The proposed turbines would be multi-megawatt class machines, each with an installed electrical capacity of between 2 and 3 MW The maximum turbine parameters selected for the purposes of this EIA is a 3 MW turbine, with a rotor diameter of up to 93 m, a hub height of up to 65 m and a maximum ground to tip height of 110 m. ENVIRON 4 2 Volume 2: Main Report Chapter 4: Description of the Development

3 Inverclyde Wind Farm Environmental Statement Inverclyde Renewables LLP 4.12 The turbines would generate electricity from wind speeds between approximately 4 m/s to 25 m/s. The rotor would be 'upwind', and all rotors would turn in the same direction. The proposed turbines would operate using variable speed rotor technology, and hence operate at different rotational speeds depending on the wind speed. Rotor speeds would vary depending on the wind speed, from approximately 10 rpm (revolutions per minute) at the cut in wind speed up to a full rotor speed of approximately 20 rpm at full power output Above ground, each turbine would comprise: a tubular tower, up to 65 m high, with door and internal access systems; a nacelle housing generator, gearbox, hydraulic and electrical control systems, and externally mounted anemometry instruments; and a rotor comprising a central hub and three blades, with an overall diameter of up to 93 m Wind turbines are available in a variety of colours, the most common being white, off white or light grey. The finish is normally semi-matt. The colour of the turbines would be agreed in consultation with the planning authority, however it is anticipated that light grey turbines would be used The blades of modern turbines are generally made from reinforced composite materials (e.g. fibreglass or wood epoxy), with towers normally constructed from steel The wind turbines have a requirement to be spaced apart, so as not to interfere aerodynamically with one another. Figure 1.2: Site layout illustrates the spacing of the turbines. Turbine Transformers and Switchgear 4.17 The transformer and switchgear would be provided adjacent to each turbine, connected by a length of buried cable, to raise the generation voltage to the higher level of 33 kv to connect with the electricity transmission network. In order to manage health and safety of operatives during maintenance, the transformer and switchgear would be located externally, at the base of the turbine, within an enclosure which can be provided in various colours to suit the landscape context. The transformer and switchgear enclosure dimension would be approximately 2.5 x 2.5 m in plan and 3 m in height. Power Performance Calibration Masts 4.18 A temporary guyed mast, known as power performance calibration mast, of up to 70 m height would be erected to confirm the detailed wind flow of the site. The mast would be raised prior to turbine erection and the data gathered would be used in the acceptance tests on the turbines. Figure 4.3 shows an example of a power performance calibration mast The mast would be removed 6-12 months into the Development s operation, once sufficient data across the full range of wind conditions is gathered to prove the performance of the turbines. Foundations and Hardstanding 4.20 The wind turbines would be sited on steel reinforced concrete foundations. It is anticipated that these would be of gravity base design. Final base designs would be determined after a full geotechnical evaluation of each turbine site. Figure 4.4 gives an illustration of typical wind turbine foundation construction. Typical permanent landtake associated with the foundations for the turbine and transformer would be approximately 430 m 2. During the erection of the turbines, crane hard-standing areas would be required at each turbine base. Typically, these consist of a main crane hard-standing area adjacent to the turbine position where the main turbine erection crane would be located, plus additional areas of land required during the assembly of the main crane jib and assembly of the rotor. The hard-standing provides a hardcore platform with a total permanent land-take estimated at approximately 896 m 2 per turbine for the crane pads There would be a need to use cranes from time to time during the operational phase of the proposed Inverclyde Wind Farm; therefore the main crane hard-standing would be left uncovered to ease maintenance activities. On-site Access Tracks, Turning Heads and Passing Bays 4.22 Tracks would be required to enable the turbine components and construction materials to be transported to their locations, and to enable on-going access for subsequent maintenance visits, as illustrated in Figure 1.2. The proposed Inverclyde Wind Farm application includes for the construction of a 2.1 km access track from Dougliehill Road, across Devol Moor, to the B788 at Harelaw adjacent to the north of Devol Moor substation and a network of approximately 4.9 km of new site tracks on the west side of the B788 linking the turbines for construction, operation and decommissioning. Vehicular access would be restricted by padlocked gates to authorised vehicles only. The track across Devol Moor from Dougliehill Road to the B788 would be maintained for the duration of the operational life of the proposed Inverclyde Wind Farm to allow for any abnormal loads access; however, routine maintenance and operational staff visits in light goods vehicles or passenger vehicles would use the B788 to reach the site entrance Based on the ground conditions at the site, it is anticipated that only 'cut' track would be required. Cut tracks would be used on hard ground, typically less than 1 m depth of peat, or on steeper gradients. Short sections of floating track may be used on areas of soft ground, typically with peat depths > 1 m, although these areas have mostly been avoided through design. The need for floating tracks would be determined through detailed site investigation at the pre-construction stage. Figure 4.5 illustrates typical cut and floating track constructions All turbine access tracks would be designed to carry the same maximum loads, and each track must be capable of supporting the weight of the mobile crane and the turbine components. Nominal track running width would be approximately 5 m, plus a 0.5 m shoulder on either side (i.e. 6 m wide in total) subject to local ground conditions, and would be designed to carry an Volume 2: Main Report Chapter 4: Description of the Development 4-3 ENVIRON

4 Inverclyde Renewables LLP axle load of approximately 16 tonnes. Track widths may be slightly wider in some sections to accommodate bend radius and to make provision for passing bays and turning heads Site track routes have been designed to minimise watercourse crossings. The proposed site access tracks would include a total of seven watercourse crossings, comprising a mixture of natural and artificial drains. The type and design of stream crossing would be dependent on the stream morphology, peak flows, local topography and ecological requirements, and would be chosen so as to avoid or minimise potential environmental effects. The watercourse crossings are considered in further detail within Chapter 10: Hydrology, Hydrogeology and Geology. Access for Recreation 4.26 The site track network has been designed to make connections with the existing local path network, providing new opportunities for walking routes around Corlic Hill, linking in with existing routes from Whinhill Golf Course, the Gryfe reservoirs and Old Largs Road. 450 m of link paths would be constructed to link the site access tracks to the existing core path network. A car park providing approximately 24 parking spaces for members of the public would also be provided off the B788, opposite the existing Devol Moor substation, as shown in Figure 1.2. Suitable gates would be provided to allow pedestrian/cyclist access to the track network from the car park. Welfare, Substation and Control Building 4.27 The welfare, substation and operational control facilities would be located in a single building and associated compound adjacent to the site access on the west side of the B788, as depicted in Figure The building would be located within a compound with dimensions of 30 m x 30 m, surrounded by a perimeter security fence with gated access. The building would be configured in an L- shape with dimensions of 20 m x 6 m. Figure 4.6 provides a plan illustration of the building, with elevation drawings shown in Figure 4.7. The location of the building would require the diversion of a small drain. Further details are provided in Chapter 10: Hydrology, Hydrogeology and Geology The primary purpose of the substation would be to provide an electrical connection point for the incoming 33 kv cables from the turbine transformers. The facility would accommodate the 33 kv switchgear and provide a central metering point for measuring the energy generated by the proposed Inverclyde Wind Farm The welfare and control building would be utilised periodically by visiting maintenance staff. The facility would contain emergency first-aid equipment, a flammables/chemical store; workshop/store; storage space for tools and spares and office space for monitoring equipment; drying/changing rooms; toilets; washroom facilities and kitchen facilities. Foul wastewater would either be discharged via a septic tank and soakaway, or by tankering and off-site disposal, depending on the suitability of the site for a soakaway and prior agreement with SEPA. Underground Cable Network Inverclyde Wind Farm Environmental Statement 4.31 Electrical connection from the turbines to the on-site substation would be via a network of underground 33 kv cables. As far as possible cables would follow the routes of the site tracks to minimise ground disturbance. The cables would be laid in trenches of approximately 450 mm wide to a depth of around 1 m. The temporary land disturbance associated with the cable trenches are covering in the land take figure presented for access tracks in Table 4.3. The distance of the trench from the track would be dependent on the ground conditions Figure 4.8 illustrates the typical cable trench detail that would be used. Connection to Electricity Grid 4.33 The grid connection does not form part of the planning application for the proposed Inverclyde Wind Farm. Any required consent for the grid connection would be typically be sought by the relevant owner of the local distribution or transmission network. The grid connection proposals would be subject to a separate consent process Nevertheless it is anticipated that the most likely connection point would be into the electricity grid at the Devol Moor 33 kv/132 kv substation via an underground cable. Devol Moor substation is located approximately 60 m east of the proposed Inverclyde Wind Farm substation, on the opposite side of the B788. Temporary Construction Compounds 4.35 A temporary construction compound would be required to enable construction of the proposed Inverclyde Wind Farm. The compound would include: temporary portable office accommodation; toilet and welfare facilities; storage for tools, small plant and parts; parking; a receiving area for incoming vehicles; and a bunded area for storage of fuels and oils The temporary construction compound would have dimensions of approximately 50 m x 60 m (3,000 m 2 in total). The indicative layout of the temporary construction compound is shown in Figure 5.1. In addition, a satellite compound for material laydown during track construction would be required within the site area to the east of the B788. Borrow Pits 4.37 To minimise the volume of stone brought onto the site and any associated environmental effect, a borrow pit located within the site would be used to source the majority of the necessary material for track construction A borrow pit search area has been identified, shown on Figure 4.1 and detailed in Technical Appendix 5.1, including illustrative layouts. The extent of the proposed borrow pit area is ENVIRON 4 4 Volume 2: Main Report Chapter 4: Description of the Development

5 Inverclyde Wind Farm Environmental Statement Inverclyde Renewables LLP 7,662 m 2. It is anticipated that approximately 35,000 m 3 of stone would be extracted from the borrow pit. The exact location of the borrow pit and its dimensions would be established following detailed geotechnical investigation for the borrow pit search area. The borrow pit would be restored following extraction of stone. Details of the borrow pit restoration proposals are provided in Chapter 5: Construction and Environmental Management and Chapter 7: Ecology. Operation and Management Life of the Project 4.39 The expected operational life of the proposed Inverclyde Wind Farm is 25 years from the date of commissioning. At the end of this period, a decision would be made as to whether to refurbish, remove, or replace the turbines. If refurbishment or replacement were to be chosen, relevant planning applications would be made. If a decision were to be taken to decommission the proposed Inverclyde Wind Farm, this would entail the removal of all the turbine components, transformers, the substation and associated buildings. The access tracks would be left on the site to ensure the continued benefit of improved access for the landowner, tenant farmer and the public for recreation or they could be reinstated. It is not currently best practice to remove the concrete foundations from the site as this would cause more damage than leaving them in situ. The exposed concrete plinth would be removed to a suitable depth below ground level and the entire foundation would be graded over with soil and would be replanted. This follows advice originally given in PAN 45, which advises in paragraph 33 that concrete foundations may be best left in place and covered over. This advice is also repeated in the Scottish Government's web-based renewables advice. Health and Safety 4.40 The health and safety of staff and the public is of paramount importance to the Applicant. Strict health and safety procedures would be applied during the construction and subsequent operation of the proposed Inverclyde Wind Farm and would be in compliance with prevailing legislation and best practice, currently set out in: the Construction (Design and Management) Regulations 2007 (HSE, 2007); the Health and Safety at Work Act 1975 (HMSO, 1974); the Construction (Health, Safety and Welfare) Regulations 1996 (HMSO, 1996); the revised edition of the Renewable UK Health and Safety in the Wind Energy Industry Guidelines; and the Management of Health and Safety at Work Regulations 1999 (HMSO, 1999) A sign would be placed at the entrance to the proposed Inverclyde Wind Farm giving details of emergency contacts. This information would also be made available to the local police station and the grid operator. Environmental Management Systems (EMS) 4.42 The Applicant has confirmed that the proposed Inverclyde Wind Farm would operate under an ISO accredited Environmental Management System (EMS). The EMS would ensure an environmental monitoring and maintenance programme is in place to ensure continued monitoring of environmental conditions on site and to prevent any adverse effects arising during the operation of the proposed wind farm Further details of the environmental management systems that would be in place during the construction of the proposed Inverclyde Wind Farm are detailed within Chapter 5: Construction and Environmental Management. Operational Residues and Emissions 4.44 This section provides an estimate, by type and quantity, of the expected residues and emissions resulting from the operation of the development. Water 4.45 Water emissions resulting from the operational wind farm are anticipated to be limited to surface water, and very small quantities of waste water from the site welfare facilities The site would be designed to ensure that surface water runoff does not exceed the predevelopment volume or rate of run-off. Access tracks would be designed to be semi-permeable and to act in a similar manner to a Sustainble Drainage System (SUDS), allowing some infiltration of surface water through the track surface. In addition, there would be a trackside drainage system installed during construction incorporating measures to attenuate the flow and provide for physical filtration and infiltration of surface water. Runoff from areas of impermeable hardstanding such as crane pads and foundations is expected to infiltrate locally on unsurfaced areas. Water quality monitoring during the operational phase would allow early detection of potential pollution incidents and assurance as to the on-going performance of the SUDS. Further detail on the surface water management proposed during construction is provided in Chapter 5: Construction and Environmental Management Small volumes of foul wastewater would either be discharged via a septic tank and soakaway, or by tankering and off-site disposal, depending on the suitability of the site for a soakaway and prior agreement with SEPA. Air 4.48 Due to the nature of the development no significant point source air emissions would be produced during the operation of the proposed Inverclyde Wind Farm. The proposed Inverclyde Wind Farm would generate renewable electricity and would therefore displace carbon dioxide (CO 2 ) emissions associated with electricity generation, which would otherwise be supplied via other forms of power generation requiring the combustion of fossil fuels. CO 2 Volume 2: Main Report Chapter 4: Description of the Development 4-5 ENVIRON

6 Inverclyde Renewables LLP Inverclyde Wind Farm Environmental Statement Waste savings of approximately 27,000 tonnes per year are predicted compared to using a grid mix of electricity generation The power generation aspect of the proposed Inverclyde Wind Farm would not produce any waste emissions or pollutants. The general operation and maintenance of the development has the potential to produce a small amount of waste. This is likely to be restricted to waste associated with the welfare building from employees and visiting contractors and the storage of oils and lubricants. Further details are provided in Chapter 5: Construction and Environmental Management. Noise and Vibration 4.50 The wind turbines would generate noise during operation, and the noise levels would vary according to the wind speed. The location of residential receptors in relation to the wind farm was one of the key considerations in the design development process. Full details of the noise impact assessment are presented in Chapter 13: Noise and Vibration. Light 4.51 Security lighting would be provided for the combined substation/ control building/ welfare building; however this would only be in use when personnel are present on site. No lighting would be provided on the proposed turbines. ENVIRON 4 6 Volume 2: Main Report Chapter 4: Description of the Development
