To whom it may concern,

Request for a formal EIA screening opinion for the erection of a single wind turbine, up to 135m to tip, on Imerys land, Land at East Karslake, Cornwall, PL26 7XS.

CleanEarth (CE) are proposing to submit a planning application for a single turbine development on land at East Karslake, Imerys, Cornwall, PL26 7XS. CE seeks to gain a formal screening opinion and formal pre-planning consultee comments for this site. The provisional turbine locations are shown in drawings CE3405-SC-TL-01 and CE3405-SC-SL-01. CE has provided a detailed description of the project and evaluated this against Environmental Impact Assessment (EIA) regulations to support our screening request.

1. The Development

The proposal is to install a single turbine of maximum tip height 135m, with a 3-bladed rotor design. Due to constant industry developments, the turbine model has yet to be finalised. Supplementary elements include two permanent switchgear housing units (approx. 4m x 4m x 3m), temporary access track, underground cabling, and temporary crane hard standing area (approx. 45m x 65m).

CE looks to develop sites that have reduced environmental impacts considering proximity, noise and visual amenity to ‘sensitive receptors’ (residential dwellings), ecological constraints, existing infrastructure, and locally designated areas and features.

1.1 Installation

The turbine and other components would be delivered to the site by an articulated lorry. The proposed route follows existing public and private highways and access may need to be established within the land boundary to the turbine base. A temporary crane hard standing area (approx. 45m × 65m) will be required for the tower, nacelle, and blade installation, this typically takes 2-3 days, after which the land will be returned to its original state.

1.2 Electrical Connection

The transformer and electrical switching system for connecting the wind turbine to the local grid will be contained within two small weatherproof housing units (approx. 4m x 4m x 3m), positioned adjacent to the tower. Local grid connection will be part of a separate application, undertaken by the local network operator (in this case Western Power). Underground cabling will be used where practical.

1.3 Decommissioning

The operational lifespan of the turbine is 35 years, after which the turbine will be decommissioned. This site would then be reinstated to its former state or a condition agreed with the Local Planning Authority (LPA).

2. Screening Opinion

Wind turbine installations are erected to harness wind power for energy production and are specified in Schedule II of the Town and Country Planning (EIA) Regulations 2017. This correspondence constitutes a formal request for a screening direction under the above regulations. With the above regulations in mind, we have provided an assessment of the project against the criteria stated below.

2.1 Schedule II of the TCP Regulations

This regulation identifies the threshold criterion which, if exceeded, requires a formal assessment to be undertaken against Schedule 3 of the TCP Regulations to determine whether an EIA Is required.

The applicable threshold criterion is stated in two points within Schedule 2 section 3(i):

"(i) the development involves the installation of more than 2 turbines; or

"(ii) The hub height of any turbine or height of any structure exceeds 15 meters ... "

The proposed wind turbine exceeds the hub height threshold and therefore is a Schedule 2 development that requires a formal assessment against Schedule 3 as to whether an EIA is required.

2.2 Summary of Schedule 3 of the TCP Regulations Assessment

Schedule 3 of the TCP Regulations set out the selection criteria for screening a Schedule 2 development. This determines whether the project is likely to have significant effects on the environment, assessing factors such as nature, size and location of the turbine. Our assessment is shown in Table 1 and summarised below.

• The turbine is not proposed in a sensitive or vulnerable location and the turbine footprint is proposed in an industrial setting, close to the Longstones operational clay mining pit. The location is within the landscape character type (LCA) CA17 or Hensbarrow China Clay Area, which has been highlighted to have no greater sensitivity to one turbine size more than the other, providing the wind development does not comprise of multiple turbines. There are no designated scenic areas within the LCA, as it is dominated by china clay workings which create an ever- changing and man-made landscape. In addition, the most recent draft development plan maps deem this area (RLU 13) to have moderate to high sensitivity towards band D turbine developments. Clean Earth propose to develop a single large-scale turbine and as such would not lead to significant landscape or visual impacts on this LCA.

• The closest Special Area of Conservation (SAC) to the proposed turbine location is the Breney Common and Goss and Tregoss Moors located 3.72km northwest at its closest point. This area was designated for its various habitats including wet heaths, dry heaths, acid grassland, bog, swamp, fen, and open water communities. The SAC is located 6.52km north at its closest point to the proposed turbine location and is designated for the various habitats it encompasses including the tidal rivers, estuaries, and mudflats. The proposed turbine is separated from these designations by an industrial landscape, china clay mining activity and two operational wind developments, therefore no additional significant impact on these designations are expected. There are no other Special Areas of Conservation within 10km of the proposed development.

• The closest SSSI is SSSI, located 1.57km to the east of the proposed location which is designated for its significance in providing evidence that the original intrusion, a biotite granite of variable grain size which has been altered by two metasomatic events. The next closest SSSI is St Mewan Beacon, located 1.85km south of the proposed location, designated for its documentation of an important evolutionary stage between late-stage granite processes and later mineralising events in south-west . Trelavour Downs SSSI, located 3.36km northwest of the proposed site is designated for being the best-known locality for biotite mica in Britain. St Austell Claypit SSSIs are located 3.36km north, 3.6km east, and 4.16km to the west of the proposed site. These sites are designated for their habitat that supports important populations of the internationally rare liverwort western rustwort Marsupella profunda. The next closest SSSI is the Mid Cornwall Moors SSSI which is located 3.7km north of the site at its closest point to the proposed site which is designated for its diverse mosaic of semi-natural habitats, including heaths, fens, grasslands, woodlands, ponds, and waterways. Tregargus Quarry SSSI, located 3.85km west of the proposed site, is designated for its excellent exposure of two late-magmatic varieties of the varied St. Austell granite mass (of Permo- Carboniferous age). Roche Rock SSSI is located 4.2km north of the proposed site and is designated for its archaeological importance and for providing the finest example of quartz-tourmaline rock in Britain. Carn Grey Rock and Quarry is located 4.65km east of the location and is designated for its relative contributions of magmatic and metasomatic processes in the evolution of the St Austell mass as a whole. Due to the

3

nature of these SSSI designations and because of no infrastructure or access proposed within these sites, no significant impacts are expected.

• The proposed turbine locations are not within an area of Grade 1 or 2 peat.

• Par Beach and St Andrews Road designated as a Local Nature Reserve is located 9.4km southeast of the proposed site. The area is of botanical and ornithological interest and comprises a body of open water which holds value to local anglers, wildlife, swamp, and grassland areas. Beacon, located 13.11km northeast of the proposed site is known for housing young and semi young woodland, semi-natural acid grassland and relict headland. There is no expected impact from the proposed turbine on these designated areas due to the large distances and the presence of multiple developments and industrial activity between the locations. There are no other Local Nature Reserves within 12km of the proposed turbine location.

• The closest National Nature Reserve is is located 4.13km northwest of the proposed site, consisting mainly of peatland and lowland heath. Together with the neighbouring moor to the east, it forms the Goss And Tregoss Moors Site of Special Scientific Interest (SSSI), as well as the Breney Common and Goss and Tregoss Moors Special Area of Conservation (SAC). Due to the distance between the proposed location of the turbine and the designation, and no access being proposed through the SAC, no impacts to be observed.

• There are no Biosphere Reserves within 12km of the proposed turbine location. Beyond these distances, no impacts on these designations are expected.

• There are no AONBs seen within a 5km radius from the proposed site of the turbine.

• There are no Listed Buildings in the immediate area of the turbine site. The closest is the Grade II*, Menacuddle Baptistery Church located 3.38km to the southeast of the proposed site. The Church of St John (Methodist) which is a Grade II* building is located 3.8km southeast of the proposed site. The Grade II* listed Market House and the Old Manor House are located 4.03km and 4.04km southeast of the proposed site, respectively. The Grade I listed Holy Trinity Church is located 4.09km southeast of the proposed site. The Grade II* listed, Goonvean China Clay Works Engine House with Boiler-House, Parkandillick Engine House, and Treveor Farmhouse, are located 3.56km west, 3.99km west and 4.06km west of the proposed site of the turbine. The Grade II* listed Church of St Mewan is located 3.78km south of the proposed site. The Grade II* listed Chapel Mill which is designated for its historic importance comprising a china stone mill and associated pan kiln and linhay; and Grade I listed, Church of St Stephen designated for its 18th-century origin and architecture, are both located 4.4km southwest and 4.6km southwest of the proposed site of the turbine, respectively. The Grade I Chapel of St Michael at Roche Rock designated for its historic importance and Norman Origin is located 4.18km North of the site and The Grade II* listed, Church of St Gomonda, designated for historic importance due to its 14th-century origin is located 4.35km north of the proposed site. The Grade II* listed Church of St Dennis is located 4.53km northwest of the proposed site. The Grade I

4

listed, Church of St Ciricius and St Julitta is located 5.57km east of the proposed site. The Grade II* listed sites of Long Stone, Wesleyan Chapel and Attached Schoolrooms, and Harbour Piers and Quays Including Inner Basin are located 5.17km southeast, 5.98km southeast, and 6.1km southeast of the proposed location of the site. The Grade II* listed Courtyard Walls Attached to South and East of Medros Farmhouse and Methrose Farmhouse, and Font in Courtyard and the Medros Farmhouse Methrose Farmhouse are both located 5.15km and 5.17km east of the proposed site of the turbine. The Grade II* listed Tregrehan House and Attached Steps, and Parterre Walls with Urns are located 5.96km southeast of the proposed site of the turbine. The distance, presence of visual cover in the form of topographic contours, vegetation and tree cover, industrial and residential developments located between the turbine site and the listed buildings greatly reduce the visibility of the turbine thus limiting the visual impact of the proposed turbine.

The closest Scheduled Monument (SM) is Wheal Martyn, located 1.61km east of the proposed site, which is part of the St Austell China Clay works. Hensbarrow Beacon SM is located 2.69km north of the proposed site. Platform cairn SM is located 2.4km north of the site. St Stephens Beacon SM is located 2.69km southwest of the site at its nearest point which comprises an earlier prehistoric hillfort and round cairn. The SM located 310m east of Carloggas Moor Farm is located 2.9km southwest of the proposed site. Tregargus stone grinding mill SM is located 3.99km southwest of the proposed site. The two SMs located 4.60km southwest of the proposed site consist of a cross shaft and base, and a wayside cross and cross base in St Stephens Churchyard. The SM named Sticker Camp later prehistoric-Roman round is located 4.92km south of the proposed site. The SM comprising part of a mining complex at South Polgooth Mine is located 5.44km south of the proposed site. Resugga Castle Late Prehistoric Univallate Hillfort is located 6.25km southwest of the site. Standing Cross in St Dennis Churchyard is located 4.63km northwest of the site. Medieval Chapel of St Micheal’s on Roche Rock is located 4.3km north of the site and the Churchyard Cross in Roche Churchyard is located 4.43km to the north of the proposed site. As the proposed turbine will not impact any archaeological remains, and the surrounding ground of the SMs, no significant impact on this monument is expected. At these distances, there are no significant visual impacts are expected on any of these designated Scheduled Monuments.

• There are no Designated Gardens and Landscapes in the immediate area, with the closest being Tregreham Gardens 6.34km southeast of the proposed turbine. Heligan Garden, designated for its historic origin and importance as a tourist destination at this distance, is located 8km south of the proposed site. Trewithen Gardens are located 10km southwest of the proposed site of the turbine. There are no other designated gardens within 10km of the proposed site and at these distances, no impact is to be expected.

• The site was selected due to its location within the industrially dominated landscape and there are very few residential properties in the surrounding area. The siting guidance within the ‘Landscape strategy and Guidance for wind turbines’ document produced by Cornwall Council was considered which states that turbines should be

5

sighted within the mining landscapes in the centre of the LCA and in the areas of more regular field patterns which tend to occur on higher ground away from the river valleys and older settlements. The proposed turbine location had an LVIA assessment completed during the existing Longstones turbine planning process, where the report described the LCA CA17 as ‘a very varied, dramatic landscape of china clay waste tips and areas of rough vegetation, characterised by open pit mining comprising of large spoil heaps and quarry pits.’ The existing turbine was said to be ‘easily absorbed within the industrial landscape’ and the landscape was said to have medium to low sensitivity to turbine development. The evidence which has been corroborated in the most recent draft development plan maps from the Cornwall Council which details the existence of a moderate sensitivity towards band D, new wind energy developments within the landscape in consideration.

• The nearest residential properties are located 967m west, 964m southeast and, 1.02km west of the proposed site of the turbine. All other properties are over 1.1km away. The applicant will ensure that the impacts are minimal and are kept within regulations and have the site of the turbine cleared from having any overbearing impacts on the local properties.

• The development will have no hazardous effects. The turbine development will have a positive environmental impact providing renewable electricity, making a small yet significant contribution towards the achievement of regional and national renewable energy targets.

• The proposed development is for a 35-year period, at the end of which it will be removed, and the land returned to its current state.

• The assessment of the turbine development against Schedule 3 shows that a significant environmental impact is not likely to arise and therefore an EIA should not be required.

3. General Considerations

Additional (non-statutory) guidance to aid planning authorities in determining requests is provided by Planning Circular 02/1999. Paragraph 33 of the circular states that:

" The Secretary of state’s view is that, in general, EIA will be needed for Schedule 2 developments in three main types of case: a. For major developments, which are of more than local importance. b. For developments, which are proposed for particularly environmentally sensitive locations; and c. For developments with unusually complex and potentially hazardous environmental effects "

We do not consider the development to fall within any of the above criteria, therefore not requiring an EIA.

6

Additionally, Annex A, paragraph A15 of the Circular states that:

"EIA is more likely to be required for commercial developments of five or more turbines, or more than 5 MW of new generating capacity."

In this case, the proposed development is for a single wind turbine with a generating capacity of 4.1MW. An EIA is therefore not considered necessary under this guidance.

Circular 02/1999 details guidance that encourages each project screening request to be judged on its own merits. The fundamental analysis is to be based on whether development and its specific impacts are likely to have a significant effect on the environment, and those that are particularly environmentally sensitive locations.

Planning Application

Following the response to this screening request, CE intends to submit a planning application for the installation of a single wind turbine. The planning application will be accompanied by an analysis of potential impacts of this development including: • Planning context • Landscape and visual impacts • Ecological impact • Cultural heritage including archaeological study • Noise • Shadow flicker • Civil aviation and MoD • Telecommunications • Transportation impact • Hydrology and contaminated land • Community benefit

The full context and detail of these analyses will be discussed and agreed upon with Cornwall Council consultees and all other stakeholders.

4. Conclusion

CE requests a screening opinion along with pre-application consultee comments.

I hope the above information has provided you with the necessary facts to help assess the requirement of an EIA for this turbine proposal. CE has considered this proposed development against the EIA regulations and has concluded that the proposed development is unlikely to result in significant effects on the environment. We, therefore, believe an EIA is not required. CE would be grateful if Cornwall Council could confirm this to be the case. If you require any further information, please do not hesitate to contact me.

Following this request, assuming an EIA is not required, a full planning application will be submitted to Cornwall Council. This will detail all the assessments stated in Section 4 as agreed with Cornwall Council Consultees.

Yours faithfully,

Table 1. Schedule 3 selection criteria for screening a Schedule 2 development

Characteristics of the development (a) The size of the The development is to be a single turbine development with development a maximum tip height of 135m. (b) The accumulation with There is considerable wind turbine development in the other development surrounding area. Those turbines which have been identified are listed below.

Approved/Constructed within 6km: • PA20/09318 1 x 135m – 327m west • PA14/12102 1 x 77m – 417m south • PA14/07230 1 x 66m – 1.61km southeast • PA15/01218 1 x 77m – 1.79km southwest • PA14/12172 1 x 77m – 2.41km Northeast • PA13/08209 1 x 77m – 5.73km Northeast

Medium-scale (up to 77m to tip) wind developments are located close to the proposed turbine locations. This proposal has been designed to be seen in conjunction with the established turbines already there, to ensure minimal additional impact. Consideration has been given to the potential cumulative impact of the proposal. This is a part of Imerys land that has ongoing china clay activity and as such is largely industrial with few residential properties in the immediate area. It is considered that the cumulative impact from a single additional turbine would be insignificant due to the proximity of the existing Higher Goonamarth turbine within 500m and the Greensplat turbine within 1.7km of the site. (c) The use of natural The natural resource of wind power will be used to supply resources renewable energy to the grid to aid in meeting government renewable energy targets. (d) The production of waste The production of waste during the turbine’s operational lifetime will be negligible. During installation, the foundation will require soil to be excavated; this will be reused on site. Additional construction waste will be appropriately disposed of offsite. (e) Pollution and nuisances Pollution and nuisances will be kept to a minimal amount during the construction phase. Transportation will be during low flow traffic periods and high noise pollution works would be during standard working hour and typically last 2-3 days. (f) The risk of accidents, Wind turbine developments do not include the use of having regard in hazardous substances. Turbine technology is safety checked particular to substances and regulated, with a good safety record. or technologies used

Location of the development (a) The existing land use The site is within a field located on inoperational land owned by the Imerys mining company, North of St Austell.

Access will utilise the existing road networks in the area, travelling south on the A38 from the Plymouth Port.

Once the turbine is erected and commissioned the land use of the site will remain as pre-installation excluding the small area occupied by the foundation and electrical housings. (b) The relative abundance, The turbine development will utilise the abundant natural quality and wind resource on-site. regenerative capacity of the natural resources in As the turbine development takes a small area (<0.1 the area hectares) of land the impact on abundance, quality and regenerative capacity of the natural resources in the area will be negligible. (c) The absorption capacity The closest Special Area of Conservation (SAC) to the of the natural proposed turbine location is the Breney Common and Goss environment and Tregoss Moors located 3.72km northwest at its closest point. This area was designated for its various habitats including wet heaths, dry heaths, acid grassland, bog, swamp, fen, and open water communities. The River Camel SAC is located 6.52km north at its closest point to the proposed turbine location and is designated for the various habitats it encompasses including the tidal rivers, estuaries and mudflats. The proposed turbine is separated from these designations by an industrial landscape, china clay mining activity and two operational wind developments, therefore no additional significant impact on these designations are expected. There are no other Special Areas of Conservation within 10km of the proposed development.

The closest SSSI is Wheal Martyn SSSI which is located 1.57km to the east of the proposed location. It is designated for its significance in providing evidence that the original intrusion, a biotite granite of variable grain size, has been altered by two metasomatic events. The next closest SSSI is St Mewan Beacon, located 1.85km south of the proposed location, designated as it documents an important evolutionary stage between late-stage granite processes and later mineralising events in south-west England. Trelavour Downs SSSI, located 3.36km northwest of the proposed site is designated for being the best-known locality for biotite mica in Britain. St Austel Claypit SSSIs are located 3.36km north, 3.6km east, and 4.16km to the west of the proposed site. The sites are designated for their habitat that supports important populations of the internationally rare liverwort western rustwort Marsupella profunda. The next closest SSSI is the Mid Cornwall Moors SSSI which is located 3.7km north of the site at its closest point to the

10 proposed site designated for its diverse mosaic of semi- natural habitats, including heaths, fens, grasslands, woodlands, ponds, and waterways. Tregargus Quarry SSSI, located 3.85km west of the proposed site, is designated for its excellent exposure of two late-magmatic varieties of the varied St. Austell granite mass (of Permo-Carboniferous age). Roche Rock SSSI is located 4.2km north of the proposed site and is designated for its archaeological importance and the finest example of quartz-tourmaline rock in Britain. Carn Grey Rock and Quarry is located 4.65km east of the location and is designated for the relative contributions of magmatic and metasomatic processes in the evolution of the St Austell mass as a whole. Due to the nature of these SSSI designations and because no infrastructure or access is proposed within these SSSI sites, no significant impacts are expected.

The proposed turbine locations are not within an area of Grade 1 or 2 peat.

Par Beach and St Andrews Road designated as a Local Nature Reserve is located 9.4km southeast of the proposed site. The area is of botanical and ornithological interest and comprises a body of open water which holds value to local anglers, wildlife, swamp, and grassland areas. Bodmin Beacon, located 13.11km northeast of the proposed site is known for housing young and semi young woodland, semi-natural acid grassland and relict headland. There is no expected impact from the proposed turbine on these LNRs due to the large distance and multiple developments and industrial activity between the locations. There are no other Local Nature Reserves within 12km of the proposed turbine location.

The closest National Nature Reserve is Goss Moor is located 4.13km northwest of the proposed site, consisting mainly of peatland and lowland heath. Together with the neighbouring moor to the east, it forms the Goss And Tregoss Moors Site of Special Scientific Interest (SSSI), as well as the Breney Common and Goss and Tregoss Moors Special Area of Conservation (SAC).

There are no Biosphere Reserves within 12km of the proposed turbine location. At these distances, no impacts on these designations are expected.

There are no AONBs seen within a 5km radius from the proposed site of the turbine. No impacts observed at further distances.

11

Characteristics of the potential impact (a) The extent of the The project scale has been chosen to reduce visual impact impact whilst gaining the most out of the available natural resource.

The Zone of Theoretical Visibility (ZTV) attached illustrates the area in which the turbine will be visible. Visual barriers such as woodland and settlements are not included in the model; therefore, the ZTV shows the worst-case scenario based on terrain only. This ZTV shows that for the worst- case scenario, the turbine will be largely visible from the immediate vicinity, with some long-range visibility found towards St. Endellion in the north and Blisland, and in the northeast and Shortlanesend and Baldhu in the southwest. Some patches of visibility can be found towards and Penpoll to the east and to the southwest. Overall, the worst-case scenario shows that most of the theoretical visibility will be limited to the immediate area.

The site was selected due to its location within the industrial dominated landscape and the few residential properties in the surrounding area. The siting guidance within the ‘Landscape strategy and Guidance for wind turbines’ document produced by Cornwall Council was considered which states that turbines should be sighted within the mining landscapes in the centre of the LCA and in the areas of more regular field patterns which tend to occur on higher ground away from the river valleys and older settlements. The proposed turbine location had an LVIA assessment completed during the existing Higher Goonamarth turbine planning process, this report described the LCA CA17 as ‘a very varied, dramatic landscape of china clay waste tips and areas of rough vegetation, characterised by open pit mining comprising large spoil heaps and quarry pits.’ The existing turbine was said to be ‘easily absorbed within the industrial landscape’ and the landscape was said to have medium to low sensitivity to turbine development.

The nearest residential properties are located 967m west, 964m southeast and, 1.02km west of the proposed site of the turbine. All other properties are over 1.1km away. The applicant will ensure that the impacts are minimal and are kept within regulations and have the site of the turbine cleared from having any overbearing impacts on the local properties.

The turbine site does not lie within any ecologically designated sites. The location is also over 50m from any woodlands and watercourses. The impact on ecology in this

12 area is likely to be small as all ecological guidance and regulations have been met.

There are no Listed Buildings in the immediate area of the turbine site. The closest is the Grade II* Menacuddle Baptistery Church located 3.38km to the southeast of the proposed site. The Church of St John (Methodist) which is a Grade II* building is located 3.8km southeast of the proposed site. The Grade II* listed Market House and the Old Manor House are located 4.03km and 4.04km southeast of the proposed site, respectively. The Grade I listed Holy Trinity Church is located 4.09km southeast of the proposed site. The Grade II* listed, Goonvean China Clay Works Engine House with Boiler-House, Parkandillick engine house, and Treveor Farmhouse are located 3.56km west, 3.99km west and 4.06km west of the proposed site of the turbine. The Grade II* listed Church of St Mewan is located 3.78km south of the proposed site.

The grade II* listed Chapel Mill designated for its historic importance comprising a china stone mill and associated pan kiln and linhay; and Grade I listed Church of St Stephen designated for its 18th-century origin and architecture, are both located 4.4km southwest and 4.6km southwest of the proposed site of the turbine, respectively. The Grade I Chapel of St Michael at Roche Rock designated for its historic importance and Norman Origin is located 4.18km North of the site and the Grade II* listed, Church of St Gomonda, designated for historic importance due to its 14th-century origin is located 4.35km north of the proposed site. The Grade II* listed Church of St Dennis is located 4.53km northwest of the proposed site. The Grade I, listed Church of St Ciricius And St Julitta is located 5.57km east of the proposed site. The Grade II* listed Long Stone, Wesleyan Chapel and Attached Schoolrooms, and Harbour Piers and Quays Including Inner Basin are located 5.17km southeast, 5.98km southeast, and 6.1km southeast of the proposed location of the site.

The Grade II* listed, Courtyard Walls Attached to South and East of Medros Farmhouse And Methrose Farmhouse, And Font In Courtyard and the Medros Farmhouse Methrose Farmhouse are both located 5.15km and 5.17km east of the proposed site of the turbine. The Grade II* listed, Tregrehan House And Attached Steps and Parterre Walls with Urns are located 5.96km southeast of the proposed site of the turbine. At these distances, no significant impact is expected.

There are no Designated Gardens and Landscapes in the immediate area, with the closest being Tregreham Gardens 6.34km southeast of the proposed turbine. Heligan Garden is located 8km south of the proposed site, designated for its historic origin and importance as a tourist destination at this

13

distance, no impacts are expected. Trewithen Gardens are located 10km southwest of the proposed site of the turbine. There are no other designated gardens within 10km of the proposed site.

(b) The transfrontier nature Impacts will be local; there will be no potential for trans- of the impact boundary impact. (c) The magnitude and All impacts will be confined to the local area. These impacts complexity of the impact are not complex and will be assessed singularly, based on their own merits, using proven methods and regulations. (d) The probability of the The site is within a field located on non-operational land impact owned by the Imerys mining company, North of St Austell.

From this assessment, it can be determined that the ecological effects of this development are likely to be minimal. Similarly, the landscape visual impacts are local with acceptable distances to neighbouring properties within an active mining landscape thereby reducing the impact of this turbine’s development. The separation distances to the nearest properties will ensure that noise and shadow flicker impacts are kept within the standard limits.

Transport impacts are expected to be negligible due to the utilisation of existing transport networks in the area.

Other possible impacts are radar, shadow flicker, and telecommunications. Initial consultation shows that it is unlikely to cause significant impacts, due to separation distances from relevant aviation infrastructures and residences.

In line with this screening request, we have also initiated a pre-planning consultation with the Ministry of Defence regarding any potential impact on aviation/radar. (e) The duration, frequency, The turbine will have an operational life period of 35 years and reversibility of the after which the turbine will be decommissioned, and the impact land reinstated to its former use.
