This document is the Non-Technical Summary (NTS) of the Environmental Statement (ES) that has been submitted alongside a planning application to Flintshire County Council for planning permission to develop a wind turbine and associated ancillary development on land at Mount Farm, Ffrith. The proposal will be referred to as Nant Y Ffrith Wind Turbine. 1.1.2. The proposed site lies approximately 2.4km south-west of the village of Llanfynydd, approximately 2.3km north of Bwlchgwyn and approximately 2.8km south of Treuddyn. 1.1.3. The proposal is for a single wind turbine up to 77m to blade tip height. The candidate turbine that is used for this application is a EWT DW54, which has a tower height of 50m and a rotor diameter of 54m, giving a total height to blade tip of 77m. 1.1.4. Nant y Ffrith Wind Energy Ltd is a subsidiary company of West Coast Energy Ltd, a privately owned renewable energy developer and has been specifically set up to develop Nant y Ffrith Wind Turbine. West Coast Energy Ltd will be the agent managing the application process. 1.1.5. Established in 1996 West Coast Energy has developed a reputation as one of the most successful independent wind energy providers, having successfully managed the completion of planning consent for wind farms and extensions, representing around 670MW of capacity, and has potential sites equating to a further 200MW at various planning and preparatory stages. 1.1.6. The Environmental Statement (ES) for Nant y Ffrith Wind Turbine has been prepared in four volumes and the contents are described below: ES Volume 1: This contains the written text of the EIA, including site selection and project description, the planning context, and various technical studies and environmental assessments independently undertaken by experienced consultants.

PROJECT DESCRIPTION Site Selection 1.2.1. The national energy policy framework provides that renewable energy resources can only be developed where they occur, and where it is economically viable to harness them. The selection of an appropriate site with the potential to support a wind development is a complex and lengthy process. It involves examining and balancing a number of technical, environmental and planning issues. Only when it has been determined that a site is not subject to major known technical, economic or environmental restrictions is the decision made to invest further resources in carrying out an Environmental Impact Assessment (EIA) and developing the detailed design of the proposed project. 1.2.2. Following the desk-based analysis, a number of site visits are then undertaken to verify information. Nant y Ffrith was identified as a potential site because of the following primary attributes: • The mean annual wind speed across the majority of the site is commercially viable; • The site does not directly affect any statutory landscape designations; • The site does not directly affect any cultural heritage or archaeological interests; • The site does not directly affect any statutory nature conservation interests; • The development would not adversely affect any telecommunication, transmission or microwave links; • The development would not adversely affect any civilian or military aviation operations or safeguarding zones; • The site is sufficiently distant from properties to enable Government prescribed noise limits to be met; • There is no potential for shadow flicker; • There is potentially a feasible and economically viable connection to the electricity grid available; • Transportation routes to the site are suitable for the construction traffic; and • The landowners are fully engaged in the project and are delighted to be part of a renewable energy project of this kind. Their day to day operations of farming can continue unimpeded during the operation of the wind turbine. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 2 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.2.3. Having identified the site as suitable in principle for a wind energy development, the layout and siting of turbine and associated infrastructure was determined through the EIA process, as reported within this ES. Environmental and technical constraints both within and outside of the development site were identified and mapped. Through a dynamic site design process of iterations and refinement, the potential impacts of the proposal have been minimised. The final design sites the turbine in order to capture the maximum wind energy whilst respecting the environmental and technical constraints. 1.2.4. Environmental constraints were identified by consultation with relevant bodies and specialist EIA studies for aspects such as landscape/visual, access / transport, ecology / ornithology and noise. These included ensuring upon adequate separation distances between turbine and neighbouring residential properties to ensure that the stringent noise emissions limits are met, and that any potential shadow flicker is minimised. 1.2.5. From the outset, the primary goal of the project was to produce a site design that is visually sympathetic and environmentally sustainable, i.e. ensuring minimal impact to the local environment through the layout of turbine position, choice of turbine engineering specifications, route of site access roads and location of ancillary structures. Site Layout 1.2.6. The layout for the proposed site is shown in Figure 1.2. The plan indicates the position of the: • A single turbine, up to 77m tip, • vehicular entrance junction; • route of the on-site access track; • substation building; and • temporary construction compound area, site office and welfare facilities. 1.2.7. The location of these project elements has been determined after a careful process of iteration and refinement as described above. Wind Turbine Specification 1.2.8. The proposal is for one turbine with a maximum height to blade tip of up to 77m when the blades reach their highest point. As is usual with any wind energy development, some flexibility is required in specifying turbine dimensions. Whilst the accompanying planning application is seeking a maximum blade tip height of up to 77m, the hub height (or tower height) and the rotor diameter of the turbine will vary slightly between different manufacturers. It is normal practice with any wind energy planning application for the final turbine dimensions, manufacturer and detailed specification to be approved at the post-consent stage through a planning condition. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 3 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.2.9. The wind turbine will be a three bladed, horizontal axis design, and have a rated capacity of 500kW. The turbine will be mounted on a tapered tubular steel tower and consist of a nacelle containing the gearbox, generator and associated equipment to which are attached a hub and rotor assembly including three glass fibre-reinforced polyester blades. At its base, the turbine tower would be approximately 4m in diameter. A transformer, sited either within the base of the tower or externally sited a few metres from the turbine tower, would boost the voltage of the turbine’s electricity output from 690 volts to 33,000 volts. Turbine Foundations & Crane Hardstandings 1.2.10. The foundation proposed for the turbine would be an inverted ‘T’ in section consisting of a reinforced central concrete pedestal approximately 3.6 metres square, together with a reinforced concrete slab approximately 12 metres square. The maximum intended depth of the foundations is approximately 3m. The tower will be attached to the foundation with 3m long foundation bolts embedded into the concrete. Figure 1.4 of ES Volume 3 contains plans and sections of the typical foundation design. Substation & Grid Connection 1.2.11. The electrical power produced by the turbine will be fed to an on-site substation by underground cables. The location of the substation is shown in Figure 1.2. 1.2.12. The substation building will measure approximately 5.3m by 3.3m by 3.3m high and will be constructed and finished using materials that are in keeping with the area and in accordance with details to be approved by planning condition by Flintshire County Council. The building will accommodate all of the equipment necessary for automatic remote control and monitoring of the wind turbine, together with the electrical switchgear, fault protection and metering equipment required to connect the wind turbine to the electricity distribution network. Further details of the substation are shown on Figure 1.5 of ES Volume 3. Site Access 1.2.13. The transportation routes and traffic impact are dealt with in section 7.5 of Chapter 7 Safety & Infrastructure, ES Volume 3. The transport route is also illustrated on Figure 1.1. 1.2.14. An existing field entrance will be upgraded in order to allow for the turbine components to be delivered. Full details of the entrance are illustrated on Figure 1.6 of ES Volume 3.

The Government is committed to increasing the proportion of energy we use from renewable sources. The UK has been blessed with a wealth of energy resources but the depletion of our domestic fossil fuels reserves, combined with projected growth in global energy demand, puts our security of energy supply at risk. 1.3.2. The UK is legally obliged to reduce greenhouse gas emissions by at least 80% by 2050. Also, under the EU 2009 Renewable Energy Directive, the UK is legally bound to achieve a target of generating at least 15% of all energy from renewable sources by 2020. 1.3.3 Much of this growth will be focused on electricity generation: to meet the 15% overall renewable energy target, a minimum of 30% of the UK’s electricity must come from renewable sources by 2020, compared with around 10% in 2013. The UK has some of the best wind resources in Europe and therefore wind power as an advanced technology can make a significant contribution to the UK’s renewable energy targets and aspirations. 1.3.4 The National Infrastructure Plan1, released in October 2010, commits the UK to creating a low carbon supply base of energy and long-term reduction in the dependence on imported hydrocarbons by developing among other projects “a world-leading array of offshore wind turbines, to exploit the UK’s abundant offshore wind-resources, supported by major investment in DC cables and manufacturing facilities at port sites and private sector investment in onshore wind turbines.” 1.3.5 The UK Renewable Energy Roadmap2 (July 2011) makes a clear commitment to increasing the deployment of renewable energy across the UK in the sectors of electricity, heat and transport. According to the Roadmap, renewables will be a key part of the decarbonisation of the energy sector necessary by 2030, alongside nuclear, carbon capture and storage, and improvements in energy efficiency. Wales 1.3.6 A Low Carbon Revolution – The Welsh Assembly Government Energy Policy Statement (March 2010). This policy statement sets out the Welsh Assembly Government’s ambitions for low carbon energy in Wales and which builds upon recent consultations including the Renewable Energy Route Map. The statement also reflects the UK policy position. 1.3.7 The statement’s aim is to renewably generate up-to twice as much electricity annually by 2025 as used today and by 2050, at the latest, be in a position where almost all local energy needs, whether for heat, electrical power or vehicle transport, can be met by low carbon electricity production. 1 2 HM Treasury, 25 October 2010, National Infrastructure Plan Department of Energy and Climate Change, July 2011, UK Renewable Energy Roadmap NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 5 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.4 BENEFITS OF NANT Y FFRITH WIND TURBINE Environmental Benefits 1.4.1 The essential benefits of using wind energy for the generation of electricity are that it is renewable, safe and does not release any gaseous emissions into the atmosphere during operation. The electricity generated by wind turbines is connected into the national electricity grid and therefore will generally displace other sources of generation, and the nature of the system is that these will normally be fossil fuel sources. 1.4.2 The installed capacity of a wind turbine is a measure of its maximum rated output, or installed capacity, which in the context of this proposal is likely to be 500kW. 1.4.3 Assuming a 500kW turbine is installed, and using a standard annual capacity load factor of 26.4%3, which takes into account the variable nature of wind frequency and speeds, it is calculated that on average around 1,156 MWh of electricity would be produced annually by the Nant y Ffrith Wind Turbine4. 1.4.4 Utilising updated figures of average UK household electricity consumption of 4,266 kWh per annum5 and a 26.4% capacity factor, computer based assessment calculates that the proposed wind turbines could each year supply the average annual domestic needs of approximately 271 homes6. 1.4.5 There has been a debate for a number of years about the actual level of emissions savings that might arise from a wind turbine development and it is very difficult to predict the exact benefit of a wind turbine development over its expected 25 year operational lifecycle. However, one certainty is that over the course of its 25 year lifetime, every unit (kWh) of electricity generated by the proposed turbine will offset large amounts of carbon dioxide (CO2) that would have otherwise been produced if that electricity had been generated using fossil fuels like coal and gas7. 1.4.6 The proposed wind turbine will therefore benefit the environment by reducing the demand for other sources of electricity, thereby replacing significant amounts of brown energy with green energy. The amount of CO2 savings made is a function of the fossil fuel displaced. The electricity industry matches the fluctuating daily and seasonal electricity demand with electricity supply from a variety of generation sources. Nuclear 3 4 5 6 7 A 26.4% capacity factor (CF) figure is derived by taking the average CF for onshore wind for the 5 year period of 2007 to 2011, as recorded in the 2012 Digest of UK Energy Statistics – Source: DECC 2012 http://www.decc.gov.uk/assets/decc/11/stats/publications/dukes/5956-dukes-2012-chapter-6-renewable.pdf. Actual capacity factor will vary year on year as there will be periods of maximum and minimal generation, depending on wind speeds and wind turbine maintenance requirements. Throughout the planning process West Coast Energy will continue to monitor the on-site wind resource. Calculated as follows: 0.5 (max installed capacity in MW) x 0.264 (capacity factor) x 8760 (number of hours in a year) = 1,156 MWh per year. The figure is presented as an annual amount in recognition of the fact that throughout the year, the figure will vary, as there will be periods of maximum and minimal generation, depending on wind speeds and wind turbine maintenance requirements.

This sum uses the UK average domestic electricity consumption of 4,266kWh per annum and a 26.4% capacity factor. Parliamentary Office of Science and Technology (1994). Select Committee Briefing: Environmental Aspects of Wind Generation. Crown press NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 6 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT stations generate at a constant rate and are termed ‘base load’ energy because of their inability to follow load fluctuations. Other sources of base load energy have in recent years been natural gas fired Combined Cycle Gas Turbines (CCGT) and large scale coal fired plant. The majority of the load following has been carried out by older, smaller but more flexible coal fired generators and it is the output from this flexible plant which is displaced by wind energy. 1.4.7 Thus, as the UK’s electricity generating mix and fuel costs will change over the 25 year expected operational lifetime of the wind turbine, it is impractical to precisely quantify the emissions savings over this period of time. 1.4.8 Renewable UK, the industry body, has taken a conservative line to quantifying the emissions savings by assuming an average of emissions across all grid-connected sources of 430g of CO2 per kWh. At planning Inquiries, it has been known for Planning Inspector’s to adopt this figure as the “minimum savings figure” from the wind turbines electricity production, and to conclude that the savings of CO2 were still substantial. 1.4.9 By using this static level of 430g of CO2 per kWh, the Nant y Ffrith Wind Turbine would offset some 12,400 tonnes of CO2 emissions over 25 years8. 1.4.10 Significant emission savings of NOx and SO2 will also result over the lifetime of the wind turbine. Once constructed, wind generation produces no carbon, nitrogen or sulphur emissions. 1.4.11 It should also be noted that the units of electricity produced by this wind turbine will displace units generated further afield by other centralised and large scale methods of generation. Embedded generation reduces the need for long distance transmission of power which produces its own losses in transmission. 1.4.12 The proposed wind turbine will therefore make an important contribution to International, European, UK and Welsh commitments to reduce greenhouse gases and tackle climate change. Further savings will accrue from reduced energy use, transportation, pollution and congestion, currently incurred in transporting fossil fuels to power stations. Economic Benefits National 1.4.13 Onshore wind energy development brings significant national economic opportunities. The recently published “Economic Opportunities for Wales from Future Onshore Wind Development” (January 2013) report jointly published by Regeneris Consulting and Economy Research Unit at Cardiff Business School was funded by the Welsh Government and the renewable energy industry in order to assess the economic opportunities from onshore wind development for wales. 8 The sum used to estimate total carbon-savings is 0.5MW x 0.264 capacity factor x 8760 hours x 430 /1000. The calculation uses the 430g C02/kWh statistic endorsed by DECC for grams of CO2 emitted when generating 1kWh of electricity.

Local 1.4.15 West Coast Energy Ltd is a leading independent wind energy developer based in Mold, North Wales. The company was established in 1996 and operates throughout the UK and has recently expanded operations into Europe. West Coast Energy Ltd falls within the West Coast Group, which comprises Atmos Consulting (an environmental and renewable energy consultancy), WCE Polska (onshore wind farm developer in Poland) and WCE Network Services (arboreal cutting services to the electrical DNOs). 1.4.16 The company has invested significantly in its Welsh headquarters in Mold, building a £2M eco office at Mold Business Park in 2009. The office building is already multi award winning and is also one of the few privately funded buildings in Wales to receive a BREEAM Excellent Rating for its environmental credentials. It also demonstrates WCE’s commitment to investing in Wales and in Flintshire. 1.4.17 The office development has provided an opportunity to continue to invest heavily in training up a skilled workforce and provide quality jobs for the Welsh economy. The company has plans to further invest in Wales in the future and believes its North Wales base and workforce makes it well placed to develop and grow as Wale’s transitions to a low carbon economy. 1.4.18 In relation to the proposed turbine, the aims of West Coast Energy are twofold; • to develop an asset base within Flintshire; • to generate local renewable energy in order to reduce the WCE Group of companies carbon footprint. 1.4.19 West Coast Energy Ltd together with its other group companies are a relatively high user of electric both within the local area and further afield in the various other offices throughout the UK. The first step of reducing the amount of electricity (and gas) the company consumes was to move the head office to a purpose built, sustainable office. 1.4.20 It is envisaged that the next part of this vision is to develop local renewable energy projects such as the Nant y Ffrith Wind Turbine in order to gain an indirect electricity supply link from a renewable energy source. This will not only allow us to have higher security of electricity price but will also significantly reduce our carbon usage, theoretically allowing us to be become a ‘Carbon Negative’ business. 1.4.21 Significant sums of money are involved in the development, construction and operation of a wind turbine. The estimated cost to construct the Nant y Ffrith turbine is approximately £1.5m. This represents a major long-term investment decision for West Coast Energy and further highlights our commitment to invest in Flintshire and the North Wales region. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 8 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.4.22 Construction of the wind turbine will require the provision of site facilities, concrete foundations and access roads together with general civil engineering resources, site cabling expertise, and the physical provision of construction plant, machinery and materials, together with site surveying and other technical service skills. This part of the work amounts to around 20% of the total construction cost. The majority of the required skills, expertise and materials will be available within the N. Wales area. Fuel Poverty National Policies & Targets 1.4.23 Whilst there is some debate on the meaning of Fuel Poverty and how it is measured, it is generally defined as a household having to spend more than 10% of income (including housing benefit) on all household fuel use to maintain a satisfactory heating regime. Where expenditure on all household fuel exceeds 20% of income, households are defined as being in severe fuel poverty. 1.4.24 West Coast Energy is committed to assist the UK Government and the Scottish and Welsh Government to tackle fuel poverty and in May 2013, the company signed a landmark partnership agreement with National Energy Action (NEA) and Energy Action Scotland (EAS). NEA and EAS are national charities which aim to eradicate fuel poverty and campaign for greater investment in energy efficiency to help people who are poor and vulnerable. 1.4.25 Following the signing of this agreement money generated from West Coast Energy’s wind energy developments in the UK will be channelled into a dedicated fuel poverty fund. This money will then be utilised by the NEA or EAS to work with Councils and local agencies to target vulnerable people and households in fuel poverty within the local and wider vicinity of its proposed developments. In Wales the fuel poverty fund will be handled by NEA Cymru. 1.4.26 West Coast Energy’s desire to reduce fuel poverty via funding from its future renewable energy developments is supported by National and local statutory targets. 1.4.27 Statutory targets for the eradicating fuel poverty in Wales were published the Welsh Assembly Government’s ‘A Fuel Poverty Commitment for Wales’9 in 2003. These targets committed the Government, as far as reasonably practicable, to eradicate fuel poverty; • Amongst vulnerable households by 2010; • In social housing by 2012; and • By 2018 there would be no-one in Wales living in fuel poverty 9 A Fuel Poverty Commitment for Wales, 2003, Welsh Government, Waleshttp://wales.gov.uk/topics/housingandcommunity/housing/publications/fuelpovertycommittment/?lang=en NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 9 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.4.28 In 2010 the Welsh Government published the ‘Fuel Poverty Strategy 2010’10 which updated the 2003 strategy but kept the statutory targets. The 2010 strategy used the results of the ‘2008 Living in Wales survey’11 to assess the scale of fuel poverty within Wales. 1.4.29 It found that 332,000 or 26% of households in Wales were estimated to be in fuel poor. It also found that a further 530,000 were spending between 5 and 10 per cent of their total household income on energy and thus were considered to be at risk of becoming fuel poor if energy prices increased or their incomes dropped. Local Policies & Targets 1.4.30 It is estimated that approximately 12%12 of all households in Flintshire are in fuel poverty. In relation to the specific local area of the proposal, it is estimated approximately 12.4-13.4%13 of all households in Llanfynydd are in fuel poverty. 1.4.31 The latest fuel poverty strategy adopted within Flintshire is contained within the Flintshire Affordable Warmth Action Plan (2009-2012) which sets out the vision and priorities of key partners working in the county to reduce a range of factors that contribute to fuel poverty. 1.4.32 The action plan contains four ‘outcomes’ to achieve; • “More people will live in energy efficient homes that can be affordably and adequately heated; • More people will benefit from available opportunities and support to maximise their income and reduce costs though benefits and accessing grants, best value tariffs and advice from experienced and qualified persons; • Resilience to future energy price rises will be improved; and • Individuals and families at higher risk of fuel poverty or who are most affected by living in cold, damp homes will receive more targets support.” 1.4.33 These outcomes have been based on the national fuel poverty strategy and focuses on the main ways to alleviate fuel poverty within Flintshire in order for the County Council to meet the targets set by the Welsh Government. 1.4.34 Through discussions with Flintshire County Council, West Coast Energy (and its partner, NEA Cymru) consider that there are synergies between our beliefs to reduce fuel poverty within Flintshire. It is therefore proposed that West Coast Energy will commit to ring fence a capitalised sum of £10,000 from the Nant Y Ffrith development for fuel poverty alleviation initiatives within Flintshire. 10 11 12 13 Fuel Poverty Strategy, 2010, Welsh Government, http://wales.gov.uk/topics/environmentcountryside/energy/fuelpoverty/strategy/?lang=en Living in Wales, 2008, Welsh Government, http://wales.gov.uk/topics/statistics/headlines/housing2009/hdw200904301/?lang=en North Wales Fuel Poverty Maps, Welsh Government, http://wales.gov.uk/topics/environmentcountryside/energy/fuelpoverty/fuelpovertymaps/northwales/?lang=en Flintshire Fuel Poverty Map, Welsh Government, 2009, http://wales.gov.uk/docs/desh/policy/090129fuelmapflintshireen.pdf NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 10 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.4.35 This initial payment could also be match funded, which would increase the funding to £20,000. This would be payable on the commissioning of the turbine when NEA Cymru would work with Flintshire Council and local fuel poverty agencies to utilise this funding to tackle fuel poverty in the local and wider Flintshire area. Community Benefits 1.4.36 In addition to the commitment of funds to help alleviate fuel poverty discussed above, Nant y Ffrith Wind Energy Ltd (NYFWEL) and West Coast Energy Ltd are committed to the principle that local communities and charitable organisations should benefit financially from the generation of local renewable energy. 1.4.37 The Nant y Ffrith Wind Turbine proposal therefore includes a capitalised sum of £10,000 which would be paid to the local community on the commissioning of the turbine. This money would be in the control of the local community and could be spent on a range of initiatives to help improve the local community. 1.4.38 Furthermore, due to the long and successful partnership between West Coast Energy Ltd and Clwyd Theatr Cymru, it is proposed that a capitalised sum of £10,000 is paid to the Theatre. It is hoped that this money will enable the theatre to introduce new initiatives and ensure existing initiatives such as FUSE can continue to prosper. 1.4.39 Nant Y Ffrith Wind Energy Ltd will ensure that legal undertakings are given to guarantee that its investment in fuel poverty alleviation, Theatr Clwyd and the local community can be secured. Public Perception & Tourism Impacts 1.4.40 The public perception of wind turbines has been assessed in a large number of surveys. These have tended to demonstrate that wind turbine development creates a broad spectrum of responses from the public with the effects on locally valued landscapes prominent in objections. 1.4.41 Of the numerous opinion studies conducted all over the UK, it has been consistently shown that the majority of the public are in favour of such development. Research has shown that the minority who disapprove of wind farms tend to be relatively forceful in expressing their disapproval, thus giving a distorted view of public attitude. 1.4.42 A recent study by researchers at Cardiff University researchers into people’s attitudes towards the UK’s energy system and renewable energy14 have found that a large majority of the British public support moves to an efficient, clean, fair, and safe energy system. The study, conducted over two and a half years, with 2,441 participants, highlighted the fact that a massive 82% of people say that they are worried about the country becoming dependent on energy from other countries and 75% support wind energy. 14 Transforming the UK Energy System: Public Values, Attitudes and Acceptability; Parkhill, K.A., Demski, C., Butler, C., Spence, A. and Pidgeon, N; July 2013 NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 11 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.4.43 Some of the other detailed findings in the report include: • 74% of participants were very or fairly concerned about climate change, while 82% were worried about the UK becoming too dependent upon energy from other countries; • 79% want to see a reduction in the use of fossil fuels over the next few decades; 81% express a desire to reduce their energy use; and support for solar (85%) and wind energy (75%) remains very strong. 1.5 ENVIRONMENTAL IMPACT ASSESSMENT 1.5.1 A summary of the findings of the various environmental impact assessments undertaken for the proposal are outlined below. Full details are available within the chapter of ES Volume 1. Landscape & Visual (Assessment undertaken by Bright & Associates) 1.5.2 This Chapter considers the likely effects upon the landscape character and visual amenity of the proposed wind turbine together with the potential cumulative effects. The assessment was undertaken by Bright & Associates and is referred to as the Landscape and Visual Impact Assessment (LVIA). 1.5.3 The design stage of the turbine height and location took into consideration the effects of landscape and visual impact. The proposal is to install a single 500kW wind turbine with a tip height of 77m, with associated access track, underground cabling, electricity sub-station and link to electricity network. Life expectancy would be 25 years followed by decommissioning and site restoration. 1.5.4 The locations of the viewpoints were agreed in consultation with Flintshire County Council. 16 viewpoints were originally proposed, and this was increased to 17 subsequent to recommendations from the Flintshire County Council’s landscape representative. 1.5.5 The nature of effect and visual implications are that the proposed scheme will not lead to an adverse nature of effect and is a scheme that can be accommodated in terms of capacity into the landscape and visual baseline without overriding significant effects. 1.5.6 The methodology for the LVIA follows recognised guidance and considers the potential effects within a study area of 15km. An extensive desk review, photographic illustration (montage) and assessment process has considered effects upon both landscape character and visual amenity. 1.5.7 The Site itself is located outside designated landscapes; with the Clwydian Range and Dee Valley AONB located to the south-west and north-west. The Site does not fall within this AONB and the overall predicted effects upon the character of this landscape are Minor. 1.5.8 LANDMAP is the formally adopted methodology for landscape assessment in Wales and informs planning related uses and landscape baseline conditions at both local and landscape scale. It is a Geographical Information System (GIS) based resource where landscape NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 12 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT characteristics, qualities and influences on the landscape are recorded and evaluated into a nationally consistent spatial data set. 1.5.9 The Countryside Council for Wales (CCW), now part of Natural Resources Wales (NRW) are in the process of publishing information on Landscape Character Areas (LCAs) at a National scale; this is currently at a draft stage. 1.5.10 Landscape character areas at a local level are defined by overlaying the different LANDMAP aspect area information and identifying areas where the combination of aspects is broadly the same and/or have distinct characteristics and a sense of identity. Landscape Effects 1.5.11 The Site and the environs around are situated within the Clwydian Range (NCA 12) Landscape Character Area as defined in the Landscape Character Map for Wales (CCW). The Site is situated within a single character type and this assists a consistent impact evaluation. This character type is noted as “a distinctive, generally rounded and heatherclad open hills, intervening vales, and contrasting rocky limestone hills on some fringe areas. Gentle to moderate slopes define the eastern side of the area towards Deeside, while steeper slopes, outcrops and cliffs characterise the western and southern sides. Land cover includes improved hill sheep grazing and lowland pasture, interspersed sporadically with areas of arable cultivation. A relatively sparse settlement pattern, confined to compact, nucleated hamlets and isolated farmsteads. Crossed by a number of arterial ‘A’ roads, the presence of the A55 Expressway across the northern part of the area is the most apparent” 1.5.12 The Site is located within the (FLNTVS006), Visual & Sensory Aspect Area (Level 3). LANDMAP describes this Aspect Area as: “Ridge- open upland ridges with a smooth profile and mixture of semi-natural moorland, rough grassland & large sized improved grassland fields, with the steeper edges covered in woodland & scrub.” 1.5.13 LANDMAP evaluates this Aspect Area as the following: “Scenic Quality: Moderate, Integrity: Low; Character: Moderate; Rarity: Moderate; Overall Evaluation: Moderate (area of local landscape value).” 1.5.14 Landscape Character has been assessed using LANDMAP Visual & Sensory Aspect Areas for Close-range (2-6km) and National Character Areas for Medium-range (2-6km) and Long-range (6.15km).The LVIA has found that the effects on character in Close-range will be Moderate in effect and this will reduce as distance increases. Beyond the Close-range, at a Medium-range and Long range the effects would be Minor for Clwydian Range (NCA12) and Negligible for the remainder National Character Areas. There is no overriding or substantial effect to the overall landscape character and the effects will be within a localised area. Therefore at a Medium and Long range there will be almost no effects on the character types. 1.5.15 There would be no significant effects upon Parks and Gardens of Historic Interest, and overall, only a Minor effect upon Designated Landscapes. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 13 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.5.16 Landscape capacity is the ability of a landscape to accommodate differing amounts of change given a specific development type. It does not directly follow that ‘significant’ effects are automatically adverse on either visual amenity or landscape character. A significant effect is not necessarily adverse when the development can be accommodated within the landscape and whilst it remains visible. Of those effects that are identified as being significant, the nature of effects can be positive, adverse or neutral and this relates to the overall context of the landscape capacity. Thus significance of effects is not so overriding as to preclude development. Positive effects can be associated with wind turbine developments where the location and siting are appropriate to the landscape. 1.5.17 In addition, it must be remembered that a wind turbine development and its effects are also reversible, in that they are only temporary for 25 years. Visual Effects 1.5.18 Visual effects have been determined with reference to representative viewpoints, selected through professional judgement, as a result of an initial desk study review and extensive field and photographic work to determine the extent of visibility and suitable locations, and with reference to the ZTV. The locations of the viewpoints were agreed in consultation with Flintshire County Council. 1.5.19 The conclusions from the viewpoint analysis are that a Moderate to Major effect has been predicted from Viewpoints 1 and 2 only, while Moderate effects are noted from Viewpoint 5, all within 2km range and in context with residential properties. 1.5.20 Outside close-range, within a Medium-range (2-6km) the assessment of viewpoints has generally predicted a Moderate or Minor-Moderate effect overall. Outside Medium-range, at 6-15km, assessment of viewpoints has generally predicted a Minor or Negligible effect. 1.5.21 From each location the degree of impact may alter between roadside impacts and those from residential properties, and in these cases the most sensitive receptors (residential) have been noted. 1.5.22 A detailed residential assessment has been undertaken for all properties within 1km of the turbine. Appendix 4.5a, ES Volume 2, shows these residential properties in relation to the proposed turbine. In summary, the visual impact assessment has predicted a Moderate effect from five properties, numbers: 1, 12, 13, 14 and 15, all of which are located to the west or south-west of the proposed turbine. However, views from all of these properties will be restricted by the intervening 1km long woodland block, which is located to the east of the properties. Other effects, those of Minor are predicted from five properties, numbers 2, 3, 4, 7 and 8. The remaining properties have predicted a Negligible or No Effect. 1.5.23 Public perception is important to understanding the value and nature of a significant effect. For the same development some may view the impact as adverse, some as positive and yet others remain as neutral. It is also likely that views may differ at different stages of the process and postconstruction, with some individuals who initially took an adverse view likely NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 14 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT to change their minds. Of those effects that are identified as being significant, the nature of effects is judged professionally and relates to the overall context of the landscape capacity. This assessment concludes the development can be accommodated within the visual capacity. 1.5.24 The Zone of Theoretical Visibility (ZTV) mapping, which is a detailed analysis technique to define visual context, is based on topography alone and does not take account of the screening effects of surface features such as hedgerows, woodlands and buildings, and as such they can present an over-representation (worst case scenario) of visibility in the study area. Sequential Effects 1.5.25 Effects from sequential routes have been considered from 4 routes which comprise relevant minor roads at a Close-range. The conclusion of the sequential route assessment is that there will only be uninterrupted views of the turbine for a very short section on Route A; where the road passes Cae hic farmstead, the assessment has identified a Moderate effect. All other routes are well screened either by the elevated landform, woodland blocks or intermittently by tall hedgerows and mature trees, allowing only glimpsed views of a very small part of the turbine. 1.5.26 The analysis of the sequential routes also demonstrated that the individual viewpoints enabled a good understanding of the visual context from other routes and that sequential visibility as a whole was not a material consideration for this development. 1.5.27 In terms of Cumulative assessment, analysis of the viewpoints where other wind turbines are noted has shown that the cumulative effect in each case is so small that there are no cumulative impacts to assess. Ecology & Ornithology (Assessment undertaken by Atmos Consulting Ltd) 1.5.28 Desk and field studies were completed to identify ecology at the Site and in the surrounding area. Desk studies included consultation with COFNOD (the local records centre for North Wales), Countryside Council for Wales (CCW) now Natural Resources Wales (NRW) and the Royal Society for the Protection of Birds (RSPB) Wales. 1.5.29 Field surveys were completed within a defined survey area, which included the site, and consisted of an extended Phase I habitat survey and great crested newt surveys. Due to the scale of the small scale of the development and its compliance with bat survey guidance adopted by NRW (Natural England, TIN051 and TIN059), it was agreed with NRW that no specific bat activity surveys were required. Following an ornithological walkover of the survey area and interpretation of existing records, it was similarly agreed with RSPB Wales that specific avian surveys were not required. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 15 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.5.30 A search for statutory and non-statutory nature conservation designations within a 2km radius of the survey area was undertaken. Information gathered from CCW and COFNOD confirmed there to be no designated sites within the survey area or the 2km buffer, with the closest being Coed Talon Marsh Site of Special Scientific Interest (SSSI), 2.1km north, and the Berwyn and South Clwyd Mountains Special Area of Conservation (SAC), 2.1 km to the south west. The search buffer was extended to 5km for statutory sites specifically designated for their bat or bird populations, of which there were two – Llandegla Moor SSSI and Ruabon/Llantysillio Mountains and Minera SSSI. 1.5.31 Data provided by COFNOD highlighted there to be no Local Wildlife Sites (LWS) within the Survey Area and fourteen within 2km. These nonstatutory sites can on Figure 5.1 of ES Volume 3. 1.5.32 LWS are a second tier nature conservation designation, which denotes sites considered of County value in Flintshire and, whilst a non-statutory designation, LWS sites are afforded a degree of protection in the planning process. 1.5.33 Within the proposed site, two habitat types were recorded – improved and semi-improved grassland. 1.5.34 The Flintshire Biodiversity Action Plan (BAP) lists local conservation priorities. None were recorded within the site boundary but the LBAP priority habitats hedgerows, woodlands and ponds and lakes were present within the survey area, as well as the LBAP species great crested newt. Potential impacts on these areas and species of the proposed wind turbine are not considered to be significant. 1.5.35 No ponds were present within the site boundary, but six were identified within the survey area. Great crested newt surveys were carried out and confirmed the European protected species to be present within three ponds, with a medium population size (peak count of 10). Consultation with CCW agreed there to be no need for a derogation licence subject to the wind turbine following an ‘unlicensed’ avoidance scheme and incorporating aquatic habitat restoration and/or creation, details of which are included in the ES Chapter and Appendix 5.3, ES Volume 2. Overall impacts on great crested newts were assessed to be not significant. 1.5.36 The COFNOD data search returned existing records of five bat species within 2km of the survey area, common pipistrelle Pipistrellus pipistrellus, whiskered bat Myotis mystacinus Daubenton’s bat M. daubentonii, lesser horseshoe Rhinolophus hipposideros and brown long-eared Plecotus auritus, and three genus of bats (Pipistrelle, Myotis and Rhinolophus). Due to the placement of the wind turbine at least 50m from a habitat feature and at least 600m from potential roost habitat (Mount Farm and associated trees and buildings), in accordance with guidance (Natural England, TIN051), no specific bat surveys were carried out. However the extended Phase I habitat survey included a bat habitat assessment and bats are included in the ES Chapter as a matter of good practice and to ensure legal compliance, with no impacts of significance predicted. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 16 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.5.37 As part of the ornithological assessment of the site, the existing species records provided by COFNOD and RSPB were analysed to identify those species of conservation interest that are potentially at risk from effects from a wind turbine – eleven species were recorded within a 2km buffer, and a further 20 within 5km. Species of interest included red kite Milvus milvus, hen harrier Circus cyaneus, black grouse Tetrao tetrix, curlew Numenius arquata, lapwing Vanellus vanellus, golden plover Pluvialis apricaria and greylag goose Anser anser. The habitats on site would be unsuitable for most of the species potentially at risk from a wind turbine recorded locally in contrast to the wider range of habitats in the locality that are likely to be of greater interest, including internationally and nationally designated sites. Potential impacts on this bird assemblage as a result of direct habitat loss and collision, or indirect impacts such as displacement, were considered to be not significant. 1.5.38 The wind turbine location and access track route has been specifically designed to avoid or minimise the loss of potentially sensitive habitats and to prevent or reduce effects on protected species. 1.5.39 No significant impacts were predicted for fauna and habitats identified within the development area during construction, operation, and decommissioning. Mitigation and habitat enhancement measures are recommended to ensure legal compliance and as a matter of good practice. Noise (Assessment undertaken by Atmos Consulting Ltd) 1.5.40 Potential noise effects arising from the construction and operation of the proposed wind turbine have been considered. 1.5.41 Construction noise level criteria have been defined in accordance with BS5228-1:2009. The noise level limit for daytime periods is based on 65dB LAeq, and the noise level limit for evenings and weekends is 55dB LAeq. 1.5.42 Predictions of noise from typical construction plant and activities have been undertaken in accordance with BS5228-1:2009. The construction of the turbine will not exceed the daytime noise level limit of 65dB LAeq or the evenings and weekends noise level limit of 55dB LAeq at any receptor location; therefore, construction noise effects are assessed as negligible. 1.5.43 The calculated operational noise emission levels fall below the noise level criteria which would trigger a full ETSU assessment. The impact of operational noise from the turbine is, therefore, considered as negligible and as a result, there will be no negative noise impacts associated with the operation of the proposed development. Safety & Infrastructure 1.5.44 Wind turbine technology in the UK is a safe proven technology. The wind turbines are designed and manufactured to withstand weather conditions at least as extreme as those which arise in the United Kingdom in terms of wind speeds, turbulence and temperature. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 17 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.5.45 Depending on the specific model, the turbine blades typically begin to rotate when the wind speed reaches between 3 and 5 metres per second. When wind speeds exceed around 25-30 metres per second (this will vary according to turbine manufacturer), safety mechanisms are triggered ensuring that the blades cease to rotate. This is achieved by feathering of the blades and applying the mechanical brake. Both of the safety systems, the blade pitching and mechanical brake, are of failsafe design. When the wind speed drops below the maximum limit of operation, the safety systems are re-set automatically and the turbines will start up again. 1.5.46 Turbine blades have been designed to discourage the build up of ice, which would cause the rotor of the turbine to go out of balance. In-built safety detection systems identify the accumulation of ice on the blades and automatically shut down the operation of the turbine. 1.5.47 Susceptibility to lightning strike are minimised by incorporating protection measures within the turbines that ensure lightning is conducted into the earth, avoiding any sensitive equipment components. Shadow Flicker 1.5.48 A calculation of when shadow flicker could theoretically occur, on a worst case scenario basis, has been undertaken using Garrad Hassan’s (GH) WindFarmer computer programme. The results are that no residential properties will be affect by shadow flicker as a result of the wind turbine. Aviation 1.5.49 The MOD was consulted at the scoping stage on the impact of the proposal on their radar and they responded with no objection. This consultation was based on larger turbines (125m to blade tip), and the project has now been reduced to 81m to blade tip. Transportation & Construction 1.5.50 The proposed vehicular entrance into the site is from the B5101 whilst travelling southbound, where a right turn is taken in the centre of Llanfynydd onto the unclassified road linking Llanfynydd to the A5104/Rhyd-y-Ceirw. 1.5.51 Access into the site is then taken onto the site (approximately 2.8km from the Llanfynydd junction) utilising some of the existing field entrance. The full access route from the A483 to the site is shown in more detail in Figure 1.1. 1.5.52 The development will require 12 AIL deliveries. These deliveries will be undertaken outwith peak traffic periods wherever possible, and it is envisaged that the traffic impact of these abnormal loads on the local communities will be low and temporary in nature. Once the turbine components are deposited, the haulage vehicle will reduce in length for the return journey. NANT Y FFRITH WIND ENERGY LTD NON TECHNICAL SUMMARY Page 18 NANT Y FFRITH WIND TURBINE ENVIRONMENTAL STATEMENT 1.5.53 The AIL movements will be undertaken as part of the recognised abnormal load procedure in place with Flintshire County Council Roads Department and North Wales Police, as such, the delivery of the turbine components will be well advertised in advance and be undertaken with a police escort to ensure disruption to the road network is reduced and managed. 1.5.54 The greatest number of HGV vehicle movements will be required for the delivery of the concrete for the wind turbine foundations which requires a maximum of 76 return HGV deliveries spread over a one week period during the 12- 16 week month construction period. 1.5.55 The impact of these vehicle movements associated with the foundation construction will be low and temporary in nature given the strategic nature of the roads. 1.5.56 There will be approximately 15 staff working on site who would be arriving and departing the site each day of the construction. These will be concentrated in the AM and PM peak period. The impact of these vehicle movements will be low and temporary in nature. 1.5.57 Traffic during construction, operation and decommission is concluded to have a negligible impact on transport route or the local communities as the number of vehicle movements envisaged will be low and temporary in nature.
