1 INTRODUCTION 1.1 Overview
1.1.1 In February 2010, In February 2010, Spalding Energy Expansion Limited (SEEL) submitted an application for planning permission under the Town and Country Planning Act 1990 (the Original Permission Application) to South Holland District Council (SHDC) to construct an underground gas pipeline and associated Above Ground Installation (AGI) required in connection with the Spalding Energy Expansion (SEE).
1.1.2 Amongst other documents / studies, the Original Permission Application was accompanied by an Environmental Statement (ES) (the February 2010 ES).
1.1.3 On 8 June 2010, planning permission (Reference: H16-0135-10) for the underground gas pipeline and associated AGI was granted (the Original Permission).
1.2 Purpose of this Document
1.2.1 SEEL is submitting a replacement application for planning permission to SHDC (the Replacement Application). The effect of the Replacement Application, if granted, would be to extend the time during which the Proposed Development (i.e. the underground gas pipeline and associated AGI) covered by the Original Permission can be commenced.
1.2.2 To accompany the Replacement Application, SEEL is providing the following information to SHDC:
A Replacement Application Environmental Statement Further Information Document (ES FID), which includes (amongst other items):
o Updated environmental baseline information; and,
o An assessment of whether the likely significant effects on the environment of the Proposed Development (i.e. the underground gas pipeline and associated AGI) differ from those described in the February 2010 ES; and,
- Where there is potential for the likely significant effects to differ, an updated impact assessment.
- Where there is no potential for the likely significant effects to differ, an explanation and / or supporting information.
1.2.3 Used in combination, the information in the February 2010 ES and the Replacement Application ES FID provide the results of a comprehensive and independent assessment of the likely significant effects on the environment, as described in Schedule 4 of the Town and Country Planning (Environmental Impact Assessment) Regulations 2011 (the EIA Regulations), of the Proposed Development.
1.2.4 This document is a Non-Technical Summary of the Replacement Application ES FID.

2 THE PROPOSED DEVELOPMENT 2.1 Overview
2.1.1 The Proposed Development comprises the construction of an underground gas pipeline and an associated AGI along with other necessary equipment. Other than a small increase in the proposed underground gas pipeline diameter, the Proposed Development is considered to be as described in the February 2010 ES. A summary description is provided in this sub-Section for information.
2.1.2 The proposed underground gas pipeline is approximately 8 kilometres (km) in length and will be buried between an extension of the existing AGI compound at Wragg Marsh and a new Gas Receiving Facility within the proposed SEE site. The proposed underground gas pipeline route broadly parallels that of the existing Spalding CCGT generating station underground gas pipeline.
2.1.3 Following completion of construction, the only permanent above ground features of the Proposed Development will be the associated AGI compound, aerial marker posts, cathodic protection posts, and M4 mark posts. To enable the monitoring and control of the underground gas pipeline and associated AGI, control cables between the proposed SEE site and the associated AGI compound will be installed with the underground gas pipeline.
2.1.4 Table 2.1 lists the specifications of the Proposed Development.
TABLE 2.1: SPECIFICATIONS OF THE PROPOSED DEVLEOPMENT Element Specification Comment Gas Pipeline Length 8.0 km N / A
Material High Grade Welded Steel N / A
External Diameter Up to 610 mm
Within the February 2010 ES, it was noted that the external diameter would be either 407 mm or 457 mm. It is now anticipated that the external diameter will be up to 610 mm. This does not change any other specifications, nor does it change the proposed underground gas pipeline route or construction / operation / decommissioning methods and associated ‘working width’ / easements / way leaves.

Section A – Insert 2.1A
2.1.7 The proposed underground gas pipeline commences at the proposed new AGI compound which would be an extension to the existing AGI compound at Wragg Marsh, approximately 200 m to the south of Bottom Farm, at the end of Carrington Road.
2.1.8 From the proposed new AGI compound, the proposed underground gas pipeline heads in a south west direction for approximately 1.4 km towards Bottom Yard, crossing agricultural land and several drains (DX0/1, DX0/2, DX0/3 and DX0/4). DX0/4 is Lord’s Drain, a key drainage channel controlled by South Holland Internal Drainage Board.
2.1.9 Immediately after crossing Lord’s Drain, the proposed underground gas pipeline crosses a public footpath (Path No. WSTN/7/1).
2.1.10 After passing Bottom Yard, the proposed underground gas pipeline turns directly south for approximately 120 m and crosses the Spalding CCGT generating station underground gas pipeline (SVX0/1).
Section B – Insert 2.1B
2.1.11 Approximately 30 m to the south of the crossing of the Spalding CCGT generating station underground gas pipeline, the proposed underground gas pipeline turns back in a south west direction. After approximately 250 m the proposed underground gas pipeline crosses an unnamed track (TX0/1), linking Bottom Yard and Top Yard.
2.1.12 The proposed underground gas pipeline then continues in a south west direction, crossing two drains (DX0/5 and DX0/6) and an unnamed track (TX0/2). The proposed underground gas pipeline then turns further west for approximately 100 m and crosses a third unnamed track (TX0/3).
2.1.13 After TX0/3 the proposed underground gas pipeline route turns south for approximately 1 km towards Bass Cottages. Approximately 150 m to the east of Bass Cottages, the proposed underground gas pipeline crosses an unnamed road (RDX1), built on a medieval sea defence feature known as ‘Roman Bank’ or ‘Sea Bank’, and a water main (SVX1/1).
2.1.14 The proposed underground gas pipeline then turns west for approximately 250 m, before crossing Wykeham Drain (DX1/1)
Section C – Insert 2.1C
2.1.15 After crossing Wykeham Drain, the proposed underground gas pipeline route turns south west for approximately 350 m before crossing StoneGate (RDX2) and an unnamed track (TX2/1).
2.1.16 The proposed underground gas pipeline then continues south west for 2 km, crossing Wykeham Lane (RDX3) and Wykeham Drain (DX3/1) for the second time.
Section D – Insert 2.1D
2.1.17 After crossing Wykeham Drain for the second time, the proposed underground gas pipeline crosses the A16 (RDX4), which is built on an unpiled embankment. The proposed underground gas pipeline then continues 400 m in the same south west direction, passing beneath the north-west corner of Wykeham Nurseries before crossing Marsh Road (RDX5). Marsh Road is also built on top of Sea Bank.
2.1.18 After crossing Marsh Road, the proposed underground gas pipeline passes Ornam House1, which lies immediately to the south, and then crosses a public bridleway (Path No. SPAL/14/2) adjacent to the River Welland.
1 Whilst Ornam House is marked on the Ordnance Survey Map, it is understood that this building has now been demolished.

2.1.19 The proposed underground gas pipeline then crosses the River Welland (RVX1) and finally crosses West Marsh Road (RDX6), under which a sewer is located, before reaching the Gas Receiving Facility within the proposed SEE site boundary.
Marker Posts
2.1.20 Following the completion of construction and permanent reinstatement, the underground gas pipeline will be marked. This is an important feature of all underground gas pipelines, and indeed Regulation 16 of the Pipelines Safety Regulations 1996 states that:
“For the purposes of ensuring that no damage is caused to a pipeline, the operator shall take such steps to inform persons of its existence and whereabouts as are reasonable”.
2.1.21 Accordingly, the underground gas pipeline will be marked by aerial marker posts (approximately 2 m high), cathodic protection posts (approximately 1 m high) and M4 mark posts (approximately 0.6 m high). These will be placed along the route of the underground gas pipeline to identify the existence of the underground gas pipeline and provide contact information for anyone wishing to carry out work in the area.
Crossing Schedule
2.1.22 Table 2.2 presents the crossing schedule for the underground gas pipeline.

A Note of Further Route Refinement
2.1.23 It should be noted that further minor route refinements may also occur at the detailed design stage. These would be a result of: further stakeholder consultations; land owner /
2 Construction methods / crossing techniques are described in more detail in Section 5 (Construction, Operation and Decommissioning).
SEE UNDERGROUND GAS PIPELINE AND ASSOCIATED AGI NON-TECHNICAL SUMMARY OF THE ENVIRONMENTAL STATEMENT FURTHER INFORMATION DOCUMENT
12
land occupier negotiations; accuracy of existing pipeline / services / utilities information; and, further ground investigations.
2.1.24 However, any such minor route refinements would be limited and would take place within limits of deviation of any Planning Permission and the survey area covered by the February 2010 ES and the Replacement Application ES FID, and would give rise to no significant impacts other than those described and assessed in the February 2010 ES and the Replacement Application ES FID. Further information on the survey area is provided in the Impact Assessment Sections of the February 2010 ES and the Replacement Application ES FID.
The Associated Above Ground Installation
2.1.25 During operation, the largest land take will be associated with the new AGI compound, and is expected to be approximately 0.12 ha. The overall land take associated with the existing AGI compound, the new AGI compound and the associated landscaping is expected to be approximately 0.56 ha.
2.1.26 The layout of the overall AGI compound is shown in Insert 2.2, and the elevations of the overall AGI compound are shown in Insert 2.3.

2.1.27 As with the existing AGI compound, the new AGI compound will be an un-manned facility. The new AGI compound will comprise two separate facilities: one facility owned and operated by National Grid Gas; and, one facility owned and operated by SEEL.
2.1.28 Similar to the existing AGI compound, the overall AGI compound will be protected by a steel palisade security fence approximately 2.4 m high. Two floodlights are already provided on 4 m high columns to provide adequate illumination should maintenance works be necessary in hours of darkness. In addition, one security camera is already provided on a 6 m high column.
2.1.29 The new AGI compound will be covered in a layer of suppressing membrane (e.g. Terram or similar) and stone chippings spread over it. There is no requirement for mains drainage. Run-off surface water will flow off the concrete / tarmacadam roads onto the terram and stone chippings and / or soak away trenches. Through the use of this design, the surface water run off rates post-development will be no greater than the existing surface water run off rates. No washing / toilet facilities are required. Therefore, no waste water treatment / disposal is required.
2.1.30 Landscaping will be planted in order to screen the overall AGI compound.

4 SUMMARY OF POTENTIAL IMPACTS AND ENVIRONMENTAL MANAGEMENT
4.1 Overview
4.1.1 This Section summarises the potential impacts of the underground gas pipeline and associated AGI, and the environmental management measures (i.e. mitigation and monitoring measures) which have been proposed as part of the way in which the underground gas pipeline and associated AGI is constructed / operated / decommissioned.
4.2 Construction
4.2.1 The summary of the potential impacts and environmental management measures for construction are provided in Table 4.1.
Environmental Management during Construction
Construction Environmental Management Plan
4.2.2 The Construction Contractor will be required to prepare and implement a Construction Environmental Management Plan (CEMP). The purpose of the CEMP is to:
Ensure that best practices are adopted, where appropriate, and maintained throughout construction;
Provide a mechanism for ensuring that measures to prevent, reduce and, where possible, offset potentially adverse environmental impacts are implemented;
Provide a framework for mitigating unexpected impacts during construction;
Provide assurance to third parties that their requirements with respect to environmental conditions and performance will be met;
Provide a mechanism for ensuring compliance with environmental legislation and statutory consents; and,
Provide a framework against which to monitor and audit environmental performance.
4.2.3 Accordingly, the CEMP to be prepared and implemented for the proposed underground gas pipeline and associated AGI will ensure construction work is completed in accordance with:
The Conditions of the Planning Permission;
SEEL’s contractual requirements;
Any environmental or other codes of conduct required by InterGen / SEEL;
Relevant specific mitigation measures; and,
Current best practice.
4.2.4 The requirement to prepare, agree and implement a CEMP is provided by Condition 3 of the Original Permission.
Construction Hours
4.2.5 The normal site working hours will be: 0700 to 1900 hrs Monday to Friday; and, 0700 to 1700 hrs Saturday. No work on any Sunday or Bank Holidays is proposed to be undertaken, unless such work is associated with an emergency.
4.2.6 Should a need arise, due to technical constraints or similar, with regard to carrying out certain construction work outside the above construction hours, prior written approval from South Holland District Council will be sought.
SEE UNDERGROUND GAS PIPELINE AND ASSOCIATED AGI NON-TECHNICAL SUMMARY OF THE ENVIRONMENTAL STATEMENT FURTHER INFORMATION DOCUMENT
4.2.7 The requirement to adhere to these working hours is provided by Condition 8 of the Original Permission.
4.3 Operation
4.3.1 The summary of the potential impacts and environmental management measures for operation are provided in Table 4.2.
4.4 Decommissioning
4.4.1 As the likely impacts of decommissioning are expected to be similar (and of an equal or lower significance) as the likely impacts of construction, the potential impacts and environmental management measures for decommissioning are expected to be similar as those provided in Table 4.1 for construction.
