1) INTRODUCTION

1.1 Purpose of this Document

1.1.1 The Hinkley Point C Connection application for Development Consent (the Application) was submitted by National Grid Electricity Transmission plc (“National Grid”) on 28 May 2014.

1.1.2 This updated Statement of Common Ground (SoCG) has been prepared by National Grid and provides a summary of discussions held with representatives from Natural England, in accordance with the guidance published by the Department of Communities and Local Government (Ref. 1.1) and the Preliminary Meeting invitation letter (Rule 6 Letter) from the Planning Inspectorate (PINS) dated 28 November 2014.

1.1.3 The Preliminary Meeting invitation letter states that the aim of a SoCG is to agree factual information to inform the Examining Authority and all other parties by identifying where there is agreement and where the differences lie at an early stage in the examination process. The letter also states that the SoCG should provide a focus and save time by identifying matters which are not in dispute or need not be the subject of further evidence and should state where and why there is disagreement about the interpretation and relevance of the information.

1.1.4 The advice of the Examining Authority is that a SoCG should cover the following topics where relevant:

Methodology for environmental impact assessment including assessment of cumulative effects.

Data collection routes.

Baseline data.

Data/statistical analysis, approach to modelling and presentation of results (including forecast methodologies)

Full expression of expert judgements and assumptions and identification of where applied.

Identification and sensitivity of relevant features and quantification of potential impact.

Likely effects (direct and indirect) on special interest features of sites designated or notified for any purpose.

Feasible and deliverable mitigation and method for securing such mitigation within the DCO.

1.1.5 It was envisaged that the SoCG may evolve in the period after the submission of the SoCG to PINS in February 2015 and during examination of the Application by the Examining Authority. This update (Volume 8.3.1A) provides the current position following submissions made as a result of Issue Specific Hearings, Written Questions, Written Representations and ongoing consultation with Natural England.

1.2 The Role of Natural England

1.2.1 Natural England is the government’s advisor on the natural environment. They work in partnership with local government, developers, local communities and other key stakeholders to ensure every opportunity is taken through the planning process to protect, and wherever possible enhance, the natural environment. Natural

England is a statutory consultee for environmental assessment processes (including Environmental Impact Assessment) and many development proposals including those of Nationally Significant Infrastructure Projects.

1.2.2 The statutory purpose of Natural England is set out in the Natural Environment and Rural Communities Act 2006, which states that:

“Natural England’s general purpose is to ensure that the natural environment is conserved, enhanced and managed for the benefit of present and future generations, thereby contributing to sustainable development”.

1.2.3 Section 2 (2) of the Act outlines the five general purposes of Natural England, which includes;

a) promoting nature conservation and protecting biodiversity;

b) conserving and enhancing the landscape;

c) securing the provision and improvement of facilities for the study, understanding and enjoyment of the natural environment;

d) promoting access to the countryside and open spaces and encouraging open-air recreation; and

2) PROPOSED DEVELOPMENT

2.1 Overview

2.1.1 The proposed Hinkley Point C Connection project includes the following principal elements:

construction of a 57km 400kV electricity transmission connection (see Volume 5.3.3, Figure 3.1 and Figure 3.2) between Bridgwater in Somerset and Seabank, near Avonmouth, comprising:

o installation of a 400kV overhead line; and

o installation of 400kV underground cables.

modifications to existing overhead lines at Hinkley Point, Somerset (see Volume 5.3.3, Figure 3.1.20);

construction of three 400kV cable sealing end (CSE) compounds along the route of the connection (see Volume 5.3.3, Figure 3.1.2 and Figure 3.1.6);

construction of a 400/132kV substation at Sandford, North Somerset (see Volume 5.3.3, Figure 3.1.9);

extension of the existing 400kV substation at Seabank (see Volume 5.3.3, Figure 3.1.19);

the removal of existing 132kV overhead lines and the construction of replacement 132kV overhead lines and 132kV underground cables (see Volume 5.3.3, Figure 3.1);

extensions/modifications to existing 132kV substations at Churchill, Portishead, Avonmouth and Seabank (see Volume 5.3.3, Figures 3.1.10, 3.1.16, 3.1.18 and 3.1.19); and

associated works, for example, temporary access roads, highway works, temporary construction compounds, scaffolding, work sites and ancillary works (see Volume 5.3.3, Figure 3.1).

2.2 400kV Transmission Connection

2.2.1 The main component of the Hinkley Point C Connection project is the construction of a new 400kV electricity connection of approximately 57km between Bridgwater, Somerset and Seabank Substation, near Avonmouth. The connection would comprise new overhead lines and new underground cables as described below:

400kV Overhead Line

2.2.2 The new 400kV overhead line between Bridgwater, Somerset and Seabank Substation, near Avonmouth, would comprise three parts:

1) Construction of a new 400kV overhead line of approximately 4.5km from the existing Hinkley to Bridgwater 275kV overhead line on Horsey Level (which would be uprated to 400kV operation) to the existing Hinkley to Melksham 400kV overhead line north of Woolavington.

2) Construction of a new 400kV overhead line of approximately 12.75km from the existing Hinkley to Melksham 400kV overhead line north of Woolavington to a proposed CSE compound south of the Mendip Hills and the River Axe.

10

3) Construction of a 400kV overhead line from the proposed Sandford Substation to Seabank Substation. In the Portishead/Portbury area two options are included within the Development Consent Order (DCO) application: National Grid’s preferred route (Option A); and an alternative route (Option B). The total length of the preferred route is approximately 29.8km (Option A) and the alternative route is 31.2km (Option B). Volume 5.2.1 provides further detail regarding the consideration of alternatives.

2.2.3 The 400kV overhead line would comprise conductors supported by steel lattice pylons and T-pylons. It is proposed that Sections A (Puriton Ridge), B (Somerset Levels and Moors South), D (Somerset Levels and Moors North), E (Tickenham Ridge) and F (Portishead) would utilise the T-pylon and that Section G (Avonmouth) would utilise steel lattice pylons.

Installation of 400kV Underground Cables

2.2.4 As part of the connection between Bridgwater and Seabank, National Grid is proposing to install 400kV underground cables in two locations. These comprise:

approximately 300m of underground cables between two single circuit CSE compounds on Horsey Level, north of Bridgwater (see Volume 5.3.3, Figure 3.1.2) where two trenches each with up to three cables could be installed; and

approximately 8.5km of underground cables between a CSE compound south of the Mendip Hills and the proposed Sandford Substation within which the cable sealing ends for the underground cables would be sited. The cables would be installed in four trenches approximately 1.8m deep and 2m wide each containing up to three cables (see Volume 5.3.3, Figure 3.1.6 – 3.1.9).

2.3 Modifications to the Overhead Lines at Hinkley Point

2.3.1 To connect the proposed Hinkley Point C Power Station to the high voltage transmission network National Grid is proposing to construct a 400kV substation (Shurton Substation) within the boundary of the power station complex. This substation formed part of EDF Energy’s proposals, which were granted Development Consent in March 2013 and therefore does not form part of this Proposed Development. To connect the proposed Shurton Substation to the transmission network, two of the existing overhead lines which currently connect into Hinkley B Power Station will need to be diverted into the new Shurton Substation and a new overhead line interconnector constructed between the proposed Shurton Substation and the existing Hinkley B Substation (see Volume 5.3.3, Figure 3.1.20).

2.3.2 These works would include the construction of approximately 4.5km of new 400kV overhead lines and the removal of approximately 2.3km of existing overhead lines. It is proposed that the new overhead lines would utilise steel lattice pylons.

2.4 Construction of Cable Sealing End Compounds

2.4.1 CSE compounds are required where overhead lines and underground cables connect to each other and typically include switchgear, support structures and perimeter security fencing.

11

2.4.2 Two single circuit CSE compounds of approximately 34m by 30m are proposed on Horsey Level, north of Bridgwater to achieve a crossing of electrical circuits where the new overhead line interfaces with the existing Hinkley to Bridgwater overhead line (see Volume 5.3.3, Figure 3.1.2).

2.4.3 A double circuit CSE compound of approximately 65m by 40m is proposed adjacent and east of the M5 motorway to the south of the Mendip Hills and the River Axe (see Volume 5.3.3, Figure 3.1.6). This compound provides the interface point between the overhead line proposed through the Somerset Levels and Moors and the underground cables proposed through the Mendip Hills which connect directly to Sandford Substation.

2.5 Construction of a 400/132kV Substation at Sandford

2.5.1 To maintain supplies on the 132kV distribution network following the removal of the existing 132kV overhead line, a new 400/132kV substation is proposed adjacent to Nye Road in Sandford, North Somerset (see Volume 5.3.3, Figure 3.1.9). The substation would be sited within a compound of approximately 143m by 217m and would include 400kV and 132kV electrical plant and equipment, super grid transformers (SGTs) and shunt reactors, electrical switchgear, perimeter fencing, access roads, landscaping and the cable sealing ends onto which the underground cables through the Mendip Hills would connect.

2.6 Extension of the Existing 400kV Substation at Seabank

2.6.1 To facilitate connection of the proposed 400kV overhead line onto Seabank Substation an extension to the existing substation building of approximately 24m and a minor extension to the substation perimeter fence are required together with the installation of electrical plant, equipment and switchgear (see Volume 5.3.3, Figure 3.1.19).

2.7 The Removal of Existing 132kV Overhead Lines

2.7.1 As part of the Proposed Development, over 65km of existing 132kV overhead lines would be removed. The overhead lines proposed for removal are as follows:

Approximately 53.2km of the existing overhead line (F and G Route) between Bridgwater and Avonmouth substations (see Volume 5.3.3, Figure 3.1).

Approximately 9km of the existing overhead line (W Route) between Nailsea and Portishead Substation (to be replaced with underground cables) (see Volume 5.3.3, Figure 3.1.14 – 3.1.16).

Approximately 1.5km of the existing overhead line (AT Route) to the south of Puxton (see Volume 5.3.3, Figure 3.1.9).

Approximately 550m of the existing overhead line (N Route) near Mead Lane, Sandford (see Volume 5.3.3, Figure 3.1.9).

A short section of the existing overhead line (BW Route) between Portishead and Avonmouth to achieve a crossing of electrical circuits (to be replaced with underground cables) (see Volume 5.3.3, Figure 3.1.16 – 3.1.17 and Figure 3.2).

12

Approximately 2.1km of existing overhead line (G Route) from the existing Avonmouth substation northwards (to be replaced with underground cables) (see Volume 5.3.3, Figure 3.1.18).

A short section of three existing 132kV overhead lines (G, DA and BW Routes) in the vicinity of Seabank Substation to achieve a crossing of electrical circuits (to be replaced with underground cables) (see Volume 5.3.3, Figure 3.1.19).

2.8 Construction of 132kV Overhead Lines

2.8.1 To maintain connections with the existing 132kV distribution network in North Somerset 132kV overhead line connections are required between the proposed Sandford Substation and the existing overhead lines feeding Weston-super-Mare (AT Route) (2.3km) and Churchill (N Route) (285m) and between Churchill Substation and an existing overhead line that currently bypasses the substation (264m) (see Volume 5.3.3, Figure 3.1.9).

2.9 Construction of 132kV Underground Cables

2.9.1 To facilitate construction of the proposed 400kV overhead line and to maintain connections with the existing 132kV distribution network a number of sections of 132kV underground cables are required. The underground cables proposed are as follows:

A short section of approximately 220m of underground cable (Y Route) to connect Churchill Substation with an existing overhead line that currently passes by the substation (see Volume 5.3.3, Figure 3.1.10).

Approximately 600m of underground cables (AT Route) in the vicinity of the proposed Sandford substation (see Volume 5.3.3, Figure 3.1.9).

Approximately 10km of underground cables (W Route) between Nailsea and Portishead Substation (see Volume 5.3.3, Figures 3.1.14 – 3.1.16).

Approximately 2.3km of underground cables (G Route) between the existing Avonmouth substation and just south of the Bristol to Avonmouth railway line (see Volume 5.3.3, Figure 3.1.18).

A short section of approximately 170m for Option A (see Volume 5.3.3, Figure 3.1.17 and Figure 3.2) and 620m for Option B (see Volume 5.3.3, Figure 3.1.16 and Figure 3.2) of underground cable (BW Route) to allow the 400kV overhead line to cross an existing 132kV overhead line to the north east of Portishead.

Three short sections of underground cable (G, DA and BW Routes) of between 150m and 300m to allow the 400kV overhead line to cross three existing 132kV overhead lines in the vicinity of Seabank Substation (see Volume 5.3.3, Figure 3.1.19).

2.10 Extensions/Modifications to Existing 132kV Substations

2.10.1 As a result of changes to the 132kV distribution network, modifications are required to existing 132kV substations at Churchill, Portishead, Avonmouth and Seabank

13

(see Volume 5.3.3, Figures 3.1.10, 3.1.16, 3.1.18 and 3.1.19). These works involve the installation of electrical plant, equipment and switchgear and are largely confined to within the existing substation compounds. In the case of Churchill and Seabank Substations, small substation extensions are also required to accommodate the electrical connections.

2.11 Associated works, for example, temporary access roads, highway works, temporary construction compounds, work sites and ancillary works

2.11.1 In addition to the above, a number of other works would be required during construction and operation of the Proposed Development. These include temporary masts and supports for overhead line construction, temporary and permanent access roads, modifications to the highway network and construction storage and working areas (see Volume 5.3.3, Figure 3.1).

2.11.2 The Proposed Development is summarised in Table 2.1 below stating the Sections in which each component of the Proposed Development occurs. Table 2.1 is the same description of the Proposed Development as set out in the DCO and is provided below for information.

3) ENGAGEMENT

3.1 Overview

3.1.1 Over the past four years, National Grid has undertaken consultation to help shape the route and design of the Proposed Development and the Environmental Impact Assessment of it. These are summarised below; details are provided in the Consultation Report at Volume 6.1; text describing how National Grid has considered representations at each consultation stage is provided in Volume 5.2.1.

3.1.2 Public consultation has taken place in stages as follows:

Stage 1A and 1B (2009 to 2011): The findings of the Route Corridor Study formed the basis for an extensive Stage 1 Consultation exercise. In response to requests for further information National Grid published more detail on the technical issues involved in building subsea and underground cables, together with more background on the proposals. The Stage 1 Consultation was also reopened to allow members of the public to provide additional feedback. This extension to the Stage 1 Consultation process is referred to as Stage 1B Consultation.

Stage 2: After the Stage 1A and 1B Consultations were undertaken National Grid adopted a new corporate approach to the design and routeing of new electricity transmission lines. To align with this approach the Hinkley Point C Connection project moved directly to Stage 3, as Stage 2 had been undertaken as part of the Stage 1A and Stage 1B Consultations.

Stage 3 (2011 to 2012): This began in September 2011, when National Grid announced the preferred route corridor for the proposed connection. In summer 2012 further consultation asked about what mattered to people and their communities. This included asking for feedback on the proposals for the local electricity network. In November 2012 the draft route for the proposed connection was announced and feedback was sought.

Stage 4: Statutory consultation in line with section 42 and 47 of the Planning Act 2008 was held between 3 September and 29 October 2013. This included publication of the Preliminary Environmental Information Report (PEIR).

3.1.3 Some consultation and stakeholder engagement was of particular relevance to the ES: in so far as it has informed the following:

What was assessed; the scope of the EIA. Early in the Scoping Stage, Thematic Groups involving key stakeholders such as Local Planning Authority specialists and statutory consultees were established for Biodiversity, Landscape and Views and Historic Environment. These groups provided advice on baseline conditions and the scope of the assessment. The Scoping Report was published In April 2013; a formal Scoping Opinion was received and responded to in the next stage of the ES.

The Preliminary Assessment; the Statutory Stage 4 Consultation. The PEIR built on the Scoping Report, taking account of representations at Scoping Stage, and provided high level information on the potential effects of the Proposed Development. The report was consulted upon and the representations received helped to inform the assessments in the ES.

18

Following the publication of the PEIR stakeholder engagement has included further Thematic Group meetings, topic specific meetings and one to one meetings with stakeholders and statutory consultees, to inform more detailed assessment and subsequent mitigation strategies.

Short periods of written engagement have also taken place to determine the method and projects covered in the cumulative effects assessment; this is set out in Volume 5.17.1, paragraphs 17.2.37 – 17.2.42 and paragraphs 17.2.48 – 17.2.53.

Written engagement on the ‘Draft ES’ to inform the assessments and mitigation measures prior to their finalisation in the DCO submission. The Draft ES and a large number of ES Supporting Documents were provided to the Joint Councils over a period of two weeks between 3 and 17 February 2014.

3.1.4 Further details of the consultation and engagement of relevance to the ES are provided in Volume 5.5.1, sections 5.4 and 5.5 and Volume 5.5.2, Appendices 5B and 5C. In addition, each topic chapter (Volume 5.6 to 5.16) include key issues arising from the consultations.

3.1.5 Following the submission of the DCO application to PINS in May 2014, National Grid has continued to engage with representatives from Natural England with specific regard to the SoCG. These activities are summarised below in Table 3.1. There have also been exchanges of information (email, telephone) between National Grid and Natural England not referred to in Table 3.1 below.

3.1.6 Consultation has continued throughout the examination period, the output of which has been submitted to and published by PINS.

Agree

Natural England

Natural agrees with the locations of bird diverters south of Mark.

Natural England agrees that bird diverters installed from the outset at Hallen Marsh would be the most effective and precautionary option. However, we believe that the alternative option of a post-construction monitoring and mitigation strategy is acceptable.

National Grid

National Grid has developed a strategy for bird collision monitoring and mitigation at Hallen Marsh which National Grid will deliver. This is not the preferred option for BCC who is requesting diverters be installed from the outset. National Grid has also provided an alternative option of fitting bird diverters. Either option would be secured through Schedule 3, Requirement 13 of the DCO.

8.22 Natural England agrees that the locations and methods of the collision monitoring is appropriate. Natural England also agrees that the fitting of additional bird diverters is an appropriate action if monitoring identifies the need and has agreed the collision thresholds which would trigger the need to implement such additional mitigation.

Natural England agrees with the proposal to fund a radio-tagging survey to investigate bird movements between the Somerset Levels & Moors and the Severn Estuary and agrees the s106 is an appropriate method for securing this funding.

17.3 and 17.4

Natural England agrees that the description of the cumulative landscape and visual effects (and residual cumulative effects) in relation to the Mendip Hills AONB and its setting is accurate based on its understanding of the surface infrastructure required for the undergrounding scheme.

Agreed, however Natural England recommends that the AONB Unit’s advice, based on a more detailed local knowledge of landscape character, can help to confirm this. From the information provided to date and as a result of visiting the area Natural England does not believe that cumulative effects would be unacceptable or outweigh the benefits of the proposed undergrounding cables scheme.

17.5 Natural England agrees that the description of the cumulative effects on national and international designated wildlife sites (and residual cumulative effects) is accurate.
