Breagh Environmental Statement Section 1 - Introduction 1.1. Aim of the Project The purpose of the project is to develop the Breagh field in order to deliver hydrocarbons to the UK and to install a gas export route from Block 42/13 to the Teesside Gas Processing Plant (TGPP) for future developments. 1.2. Purpose of the Environmental Statement The purpose of this Environmental Statement (ES) is to report on the Environmental Impact Assessment (EIA) process undertaken to meet both statutory and RDUK’s project requirements. The ES was prepared in accordance with the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) (Amendment) Regulations 2007. The ES reports on the conclusions from the EIA, which investigated and evaluated routine and non-routine environmental impacts associated with the development, specifically: atmospheric emissions, physical presence of installation vessels, impacts of drilling and testing the new wells and installation of the export pipeline. The presence of permanent new subsea infrastructure and the fate of potential hydrocarbon spills from all stages of the project were also included. 1.3. Requirement for an Environmental Statement The ES documents the results from the Environmental Impact Assessment (EIA) of the proposed project. The EIA was carried out to ensure that the environmental impacts associated with the project were identified and their significance assessed, and that appropriate mitigation and control measures are implemented. The Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Amendment) Regulations 2007 requires: 1) evaluation of projects likely to have a significant effect on the offshore environment; and 2) formal public consultation on the resulting ES. The ES is also required to take into account European Directives, in particular the EU Habitats Directive 92/43/EEC (enacted in the UK by The Offshore Petroleum Activities (Conservation of Habitats) Regulations 2001, SI 2001 No. 1754 and the EU Birds Directive 79/409/EEC. RDUK has an HSEQ-EMS in place which ensures that: 1. There is an effective management organisation in place to plan operations to minimise the impact to the environment by identifying and managing the relevant risks. 2. Environmental issues are considered from the outset when planning operations, to reduce waste, the consumption of resources and prevent damage to wildlife habitats. 1-2
1.4. Scope of the Environmental Statement Breagh Environmental Statement Section 1 - Introduction The scope of the EIA and this resultant ES includes all activities associated with the Phase 1 of the offshore development of the Breagh Field up to the landfall at the Mean Low Water Springs (MLWS) line. The proposed scope of the offshore Phase 1 development is to: • Install the Breagh A NUI; • Drill 7 target wells (including re-drilling in two existing wells at the platform location); • Install approximately 100 km of 20” export pipeline, 3” MEG line and fibre optic cable between Breagh A and the landfall at Teesside; • Test and commission all the facilities; • Produce gas and condensate. The landfall and terminal impacts are considered under a separate submission as required under the Town and Country Planning Act (Figure 1-2). Figure 1-2 Environmental Statement Demarcation 1.5. Legislative Overview This section provides a brief overview of the current legislation. A full summary of applicable legislation is included in Appendix A of the ES. Current offshore environmental control has evolved over the past thirty years and is continuing to evolve in response to increasing awareness of the potential environmental impact. Strands of both primary and secondary legislation, voluntary agreement, and conditions in consents granted under the petroleum licensing regime and international conventions have also contributed. 1-3
