1 INTRODUCTION

1.1 About this Document

1.1.1 Scottish Hydro Electric Transmission Plc (SHE Transmission) has submitted an application for consent1, to construct and operate a new 19 kilometre (km) double circuit 275 kilovolt (kV) overhead electricity transmission line (OHL), supported by steel lattice towers, between the existing Knocknagael substation, and a proposed new substation near Tomatin, approximately 1 km north of Garbole. The proposed new substation will be subject to a separate consenting process. In addition, SHE Transmission is seeking to construct and operate 4.5 km of 132 kV OHL between Tower 127 and Tower 137 to connect the proposed Tomatin Substation to the 132 kV transmission network. The location of the Proposed Development is shown in Figure 1.

1.1.2 This document is the Non-Technical Summary (NTS) of the Environmental Statement (ES) which reports on the findings of the Environmental Impact Assessment (EIA) of the Proposed Development. The ES has been prepared to accompany the application for consent.

1.2 Project Background

1.2.1 SHE Transmission is the transmission licence holder in the north of Scotland. This means that SHE Transmission has a legal duty to facilitate competition in the generation and supply of electricity through offering connections to the transmission system, both for new generation and for new sources of electricity demand.

1.2.2 There is 212 megawatts (MW) of new renewable energy generation projects requiring connection to the transmission network in the area to the south of Inverness, including the Glen Kyllachy, Tom nan Clach wind farms. There are also further wind farms in the early stages of development, which if progressed could contribute up to a further 67.5 MW of renewable generation. The contracted generation significantly exceeds the capacity of the existing transmission network, which comprises an existing 132 kV double circuit OHL between Beauly and Boat of Garten (as shown in Figure 2). As such, the significant volumes of new generation proposed to the south of Inverness, combined with the lack of capacity in the existing network, has triggered the need for reinforcement of the existing electricity transmission network in the area.

1.3 Purpose of the Non-Technical Summary

1.3.1 The aim of this NTS is to summarise the content and the main findings of the ES in a clear and consistent manner to assist members of the public in understanding what the environmental effects of the Proposed Development are likely to be. The full ES (Volume 2: Main Report; Volume 3: Figures; Volume 4: Technical Appendices) provides a more detailed description of the Proposed Development, and the findings of the EIA.

2 DESCRIPTION OF DEVELOPMENT

2.1.1 The Proposed Development would comprise approximately 19 km of 275 kV overhead line (OHL) and 4.5 km of 132 KV OHL supported by steel lattice towers. The route of the OHL commences from the existing Knocknagael substation on the southern fringe of Inverness and would connect to the proposed new Tomatin substation, located in Glen Kyllachy, approximately 1 km north of Garbole and approximately 6 km south-west from the village of Tomatin. . Figure 3 shows the location of the Proposed Development. The Proposed Development would include the following key components: • Sixty towers (provisionally) with a typical tower height range between 46 m and 55 m (maximum of 60 m) above ground level (agl) carrying the 275 kV conductors. The Proposed Development would include a Sealing End Compound beneath Terminal Tower 1, and the installation of 275 kV underground cables to connect the Knocknagael Substation with the Terminal Tower.

• Twelve towers (provisionally with a typical tower height range between 25 and 33 m (maximum tower height of 33 m) carrying the 132 kV conductors. The Proposed Development would include two Sealing End Compounds beneath Terminal Tower 134R and Terminal Tower 136R respectively, and the installation of 132 kV underground cables to connect the proposed Tomatin Substation with the Terminal Towers.

• The 275 kV towers would carry two circuits, with three conductor bundles (comprising two conductors separated by a spacer), supported from the horizontal cross arms on both sides of the tower. An earth wire would be suspended between tower peaks.

2.1.2 Certain ancillary works would be associated with the OHL such as the formation of temporary and permanent access tracks, and bellmouths where the proposed tracks meet public roads. Micrositing of the tower and track locations would be allowed within a proposed horizontal corridor (referred to as Limits of Deviation - LOD). Figure 3 shows the location of the proposed towers and access tracks, along with the LOD.

2.1.3 Construction of the Proposed Development is anticipated to commence in December 2016 and be completed by October 2018, with OHL works on the 132kV network commencing after this date. Track removal and reinstatement along the route of the 275kV OHL is anticipated to commence in 2019.

2.1.4 Figure 4 shows the typical lattice steel tower designs likely to be used for the Proposed Development. Typical construction activities are shown in Figure 5.

3 ROUTE SELECTION AND ALTERNATIVES

3.1 Introduction

3.1.1 SHE Transmission has addressed the majority of the potential significant environmental effects through the route selection. The route selection process, documented in a Routing Study report3, identified and assessed potential OHL route options within a Preferred Corridor, identified by an earlier Route Corridor Selection Study4. Separate comparative site selection studies, and detailed public consultation was carried out to select the site for the proposed Tomatin substation5. Various alternatives were considered during the design process: • Do-nothing: The 'do nothing' scenario would involve the electricity network remaining in its current form, which includes retaining the existing double circuit 132 kV OHL which runs from the Beauly substation to the Boat of Garten substation in its current configuration. This option is not considered viable given the need to increase capacity in order to provide connections for the proposed renewable generation projects to the south of Inverness.

• Alternative route options. Initially four OHL route corridors were considered in order to identify a preferred corridor most capable of accommodating the Proposed Development. The corridor selection and appraisal was informed by the “Holford Rules”6. Following on from this, SHE Transmission developed various OHL options within the Preferred Corridor.

• Alternative conductor and support structures: A number of alternative support structures including wood poles and underground cables were considered during the planning process; however, they were considered not to be viable due to engineering and economic reasons. Alternative conductor types and tower support structures were also considered in a study7 prepared by SHE Transmission. The preferred tower type and conductor informed the initial parameters upon which the routing process was based. Routeing Principles

3.1.2 Taking account of both SHE Transmission’s guidance8 and the Holford Rules, the following principles informed the routing process: • the need to avoid areas of highest amenity value;

• reducing visual impact by choosing the most direct line, therefore requiring fewer angle towers;

• general landscape and visual amenity (backcloth and screening);

• opportunities to mitigate the ‘wirescape’ of the area and to minimise 'new' visual impact by following the routes of existing electricity infrastructure wherever possible;

• minimise land-take, or severance, of existing agricultural land;

• minimising impact on traffic and access;

• opportunities to avoid areas of residential amenity such as residential dwellings and curtilages; and

• known information on proposed wind farms.

3.2 Consultation Stakeholder Consultation

3.2.1 A range of consultation methods were used by SHE Transmission to seek feedback on the route selection process and consideration of alternatives for the Proposed Development.

3.2.2 A Consultation Document was produced and distributed in December 2013. Public consultation events were held in November 2013, January 2014, April 2014, March 2015 and July 2015.

3.2.3 Full details of the consultation undertaken along with a summary of the responses received are provided in a Report on Consultation document (September 2015)9.

3.2.4 The final route of the Proposed Development (as shown in Figure 3) has responded where possible, to comments and concerns raised during the consultation process and is considered to represent a balance between environmental, engineering, cost and other factors. Scoping

3.2.5 A request for a Scoping Opinion was made to the Scottish Ministers in April 2015. A Scoping Report was submitted by SHE Transmission to support the request, which sought input from regarding the information to be provided within the ES.

3.2.6 After consideration of mitigation achieved through the design and route selection process, the Scoping Report identified the following key environmental issues: • Landscape and Visual;

• Ecology;

• Ornithology; and

• Archaeology and Cultural Heritage.

3.2.7 A Scoping Opinion was received from the Scottish Ministers in August 2015 confirming the proposed scope of the ES was acceptable.

4 LIKELY SIGNIFICANT EFFECTS

4.1.1 The EIA process is designed to identify significant environmental effects and detail proposed mitigation measures. Significant effects associated with the construction and operation of the Proposed Knocknagael to Tomatin OHL are limited to effects on specific landscape character areas and visual amenity.

4.2 Landscape and Visual

4.2.1 There are two Special Landscape Areas (SLAs) located within or on the edge of the Study Area: • Drynachan, Lochindorb and Dava Moor SLA is located partly within the eastern half of the study area.

• Loch Ness and Loch Duntelchaig SLA partly overlaps the north eastern portion of the study area.

4.2.2 Five Gardens and Designated Landscapes are located within, or partly within the Study Area. Four of these are considered unlikely to accrue any effects as a result of the Proposed Development. It has been identified that the Proposed Development will have a minor indirect and temporary effect on the Tomnahurich Cemetery during construction and a minor indirect and permanent effect during operation. There would be no significant effects for any area designated for landscape or scenic quality.

4.2.3 Land use in the Study Area comprises a mosaic of improved and semi improved grassland, rough grazings, moorland and commercial forestry plantations, which are usually of single species and a dark, uniform colour. Riparian woodland, occasional hedgerows and isolated groups of deciduous trees are also characteristic features of the Study Area.

4.2.4 The Study Area is characterised by concentrated and scattered settlement, isolated dwellings and farmsteads in the hinterland of Inverness which lies in the north eastern portion of the study area. The key small settlements in the Study Area include Farr, Inverarnie and Tomatin.

4.2.5 Effects of the Proposed Development have been evaluated with reference to a series of 12 viewpoint locations along the route of the Proposed Development, identified through theoretical modelling of the Zone of Visual Influence (ZVI) and verified through field visits and photography along the LOD, taking account of location of existing settlements, known cultural heritage features, roads and cycleways.

4.2.6 Significant effects are limited to six Landscape Character Types (LCTs) which are well represented in the study area and in the Inverness-shire landscape generally. The remaining LCTs which are far less well represented in the study area would not experience significant effects.

4.2.7 Visual amenity relates to the human experience of the landscape. It is therefore affected by population distribution, patterns in settlement, the nature of the location at which the impacts occur and the number and types of viewers affected. The Proposed Development introduces manmade structures into a rural landscape, therefore significant visual effects are considered likely and to an extent inevitable for some viewpoints. Significant operational effects are predicted for five of the twelve viewpoints assessed. Two sequential routes would experience significant

effects, where routes are in close proximity to the Proposed Development, for example, the B851 road at Milton of Farr. Notwithstanding the anticipated effects of the Proposed Development at these locations, visual effects of the Proposed Development for the majority of receptors are predicted as being minor and not significant, with large areas screened from the Proposed Development by topography, forestry, woodland, hedges and other local screening elements.

5 SUMMARY OF OTHER ENVIRONMENTAL EFFECTS

5.1 Ecology

5.1.1 The Proposed Development would not have any direct or indirect effects on sites, designated for habitat or non-avian species conservation.

5.1.2 Habitat surveys confirmed that the Proposed Development would cross a mix of grazed grasslands, heath and scrub, semi-natural coniferous woodland; bracken; semi-natural broadleaved woodland; dry and wet modified bogs; marshy grasslands; arable fields; blanket bog; flush; dry acid heath and wet heath. Seven small areas, limited in extent, were identified as supporting ground water dependent wetland habitats.

5.1.3 Surveys were completed for signs of water vole Arvicola amphibious, Otter Lutra, Pine marten Martes and Wildcat Felis silvestris, and Badger Meles. Red squirrel Sciurus vulgaris and Reptiles were also recorded opportunistically throughout the site surveys. Potential bat roosts such as old trees with nooks, crannies and holes, as well as suitable buildings within the LOD to be applied to the Proposed Development were recorded during the protected species surveys.

5.1.4 No significant effects as a result of habitat loss, fragmentation or degradation or direct effects on protected species have been identified. Nevertheless, good practice management measures have been identified to further avoid and reduce effects. The residual effects on ecological receptors would be negligible or minor adverse (not significant).

5.2 Ornithology

5.2.1 The Proposed Development has the potential to result in effects on three Special Protection Areas (SPAs): • The Inner Moray Firth SPA (Greylag Goose and Osprey) - at the closest point this SPA lies approximately 7 km from the Proposed Development.

• The Loch Ruthven SPA and Loch Ashie SPA, both mesotrophic lochs classified for supporting populations of Slavonian Grebe Podiceps auritus during the breeding season and on passage. At the closest point these SPAs are approximately 3 km from the Proposed Development.

5.2.2 Impact assessment considered the significance of effects on the SPA populations, and found that there are no ecologically significant effects predicted.

5.2.3 Ornithological surveys have been undertaken to determine the species and numbers of birds flying across the route of the OHL. The survey data was used to predict the probability of key bird species colliding with the Proposed Development. Mitigation in the form of line marking for part of the OHL, has been proposed to reduce the potential for red kite, white tailed eagle, goshawk and golden eagle collisions with the OHL. Markers would make the wires of the OHL more visible to flying birds and increase the birds ability to take action to avoid the OHL. Following assessment of the proposed mitigation, there are no ecologically significant effects predicted.

Scottish Hydro Electric Transmission plc Knocknagael - Tomatin 275 kV OHL

5.3 Cultural Heritage

5.3.1 There are no Scheduled Monuments or Listed Buildings within the LOD to be applied to the Proposed Development and no part of the Proposed Development would lie within a Conservation Area, Inventory status Historic Battlefield or Inventory status Garden and Designed Landscape.

5.3.2 However, 36 undesignated heritage assets have been identified within the LOD. The majority of these are former settlement remains and agrarian features ranging in date from the prehistoric period (for instance at Big Burn, Gask, Blarbuie and Tordarroch) to the post-medieval period. The assessment concluded that if these are avoided, no or minor residual impacts would occur during the construction and the operation of the Proposed Development.

5.3.3 There are either no effects, or minor (not significant) effects predicted during construction for all heritage assets identified. During the operation of the Proposed Development, minor residual indirect effects are expected on the setting of two regionally important heritage assets and nine Scheduled Monuments, one Category B Listed Building and one Category C Listed Building.

5.4 Temporary Effects

5.4.1 Impacts arising during the construction process would be temporary, generally of a short term and intermittent nature. Construction impacts such as noise and dust generation, surface water runoff and localised changes to traffic movements can be difficult to predict with any certainty as they result from specific construction activities, in certain locations at different stages of the development process. Given these uncertainties the principal activities that would occur during construction have been considered and assessed in the EIA process and the ES explains what good practice management measures and mitigation would be adopted to control them.

5.4.2 During the construction stage, micrositing under the supervision of an Environmental Clerk of Works (ECoW), would be used to avoid or reduce effects at a site level before finalising the individual tower locations and the locations of access tracks, construction work areas and laydown areas.

5.4.3 Construction impacts would be controlled through the development of a Construction Environmental Management Document (CEMD), supported by a number of project and issue specific Construction Environmental Management Plans (CEMPs). These documents would be part of the contract documentation for the Principal Contractor, employed by SHE Transmission to construct the Proposed Development. Implementation of the environmental mitigation measures as set out within the ES and the CEMD would be monitored and managed throughout the construction process by an ECoW.

5.5 Cumulative Effects

5.5.1 The ES has considered the possible cumulative effects of the Proposed Development with a number of other proposed developments including: • Wind farm developments (as shown on Figure 2); and

• The proposed Tomatin Substation.

Volume 1: Non - Technical Summary 10 LT000019

Scottish Hydro Electric Transmission plc Knocknagael – Tomatin 275 kV OHL

5.5.2 Localised cumulative impacts on the visual amenity of specific receptors are possible in certain areas along the Proposed Development, but the wider effects on the receiving landscape would be no greater than for those arising from the Proposed Development alone.
