TTGDC Thurrock Thames Gateway Development Corporation TWAO Transport and Works Act Order UK United Kingdom UPS Uninterruptible Power Supply GEC Underground Gas Pipeline and Associated Above Ground Installation July 2011 PREFACE In February 2010, Gateway Energy Centre Limited (GECL) submitted an application for consent under Section 36 of the Electricity Act 1989 to the Secretary of State for Energy and Climate Change to construct a 900 Megawatts Electrical (MWe) Combined Cycle Gas Turbine (CCGT) Power Plant to be known as Gateway Energy Centre (GEC). In addition, a direction that planning permission be deemed to be granted under Section 90 of the Town and Country Planning Act 1990 was also sought. The application was accompanied by an Environmental Statement (ES) prepared in accordance with the requirements of the Electricity Works (Environmental Impact Assessment) (England and Wales) Regulations 2000 (as amended). Following submission of the Section 36 consent application, consultation responses were received and meetings were held with key consultees from which clarifications on the application were sought and supplementary information requested. The clarifications and supplementary information were presented in an Environmental Statement Further Information Document (ES FID), accompanied by a number of supporting documents and submitted to the Department of Energy and Climate Change (DECC) in December 2010. The proposed GEC is to be located on land within the London Gateway Port / London Gateway Logistics and Business Park development, collectively called the LG Development, which is being promoted by DP World and is currently in the early stages of construction. Further to the development of GEC, GECL proposes to construct an underground gas pipeline and associated above ground installation (AGI) required in connection with the development of GEC. In March 2011, GECL submitted an application for planning permission to Thurrock Thames Gateway Development Corporation (TTGDC) under the Town and Country Planning Act 1990 for the installation of the proposed underground gas pipeline and associated AGI. The application was accompanied by an ES prepared in accordance with the requirements of the Town and Country Planning (Environmental Impact Assessment) (England and Wales) Regulations 1999, as amended. The installation of electrical infrastructure for the High Voltage (HV) grid connection associated with the development of GEC will be the subject of a separate application to be made in due course to either TTGDC or Thurrock Council under the Town and Country Planning Act 1990 and / or under the Planning Act 2008 to the Infrastructure Planning Commission (IPC), or to the Major Infrastructure Planning Unit (MIPU) which will replace the IPC. Following submission of the application for the underground gas pipeline and associated AGI, consultation responses were received and meetings were held with certain of those parties. In addition, since submission of the application in March 2011 certain changes in planning and energy policy have occurred. The ES FID and the accompanying appendices, which have been provided to TTGDC, provides further information in these regards. The following terms are adopted for the purposes of this ES FID: x “Further Information” means additional information provided by the applicant to supplement the information in the ES. x "Any Other Information" means any other substantive information relating to the ES and provided by the applicant. x “Supplementary Information” means the further information and any other information. The ES FID is provided to supplement the information provided in the ES, and will be advertised by TTGDC as if it had been requested pursuant to Regulation 19 of the Town and Country Planning (Environmental Impact Assessment) (England and Wales) Regulations 1999 (“the 1999 EIA Regulations”). Notice of the March 2011 application for planning permission for the underground gas pipeline and associated AGI, was advertised under Article 13(3) of the Town and Country Planning (Development Management Procedure) (England) Order 2010. GEC Underground Gas Pipeline and Associated Above Ground Installation July 2011 Should members of the general public wish to make a representation regarding the application for planning permission for the underground gas pipeline and associated AGI, then these should be addressed to: Matthew Gallagher Planning Development Office Thurrock Thames Gateway Development Corporation 2nd Floor, Civic Offices (CO1) New Road Grays Essex RM17 6SL Copies of the March 2011 application for planning permission (with a plan showing the land to which it relates), the ES explaining GECL’s proposals in more detail and presenting an analysis of the environmental effects of the underground gas pipeline and associated AGI, the non-technical summary (NTS) of the ES and planning statement) and the July 2011 ES FID and supplementary planning statement may be inspected during normal office hours at the following addresses: Thurrock Thames
