1 ‐ 2 Balloch Field Development Environmental Statement Section 1 Introduction The Balloch field is situated in Licence P.1041. Maersk Oil has 100 % equity and is the sole owner and operator of the GPIII FPSO. Production is expected to commence from the Balloch field in Q3 2013 and run to the end of 2019. However, it is possible that field life of the GPIII will be extended via infill well drilling and tiebacks that would in turn allow the Balloch field to continue producing. In this instance, a cessation of production (COP) would be anticipated closer to the end of 2026 with the final date for COP dependent upon well performance. Assuming a COP at the end of 2026, high case production (P10) at the Balloch development is anticipated to be approximately 3.9 million m3 of oil and 313 million m3 of gas. 1.1. PURPOSE OF THE PROJECT The purpose of the project is to develop the Balloch field in order to deliver hydrocarbons to the UK. This will in turn reduce the UK’s dependence on oil and gas imports. Taxes paid will contribute to the UK’s social programmes and provide high value employment. 1.2. PURPOSE OF 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 Maersk Oil project requirements. The ES was prepared in accordance with the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations 1999 (as amended 2007 and 2010). These regulations require: An evaluation of projects likely to have a significant effect on the offshore environment; Formal public comment on the resulting ES. The ES reports on the conclusions from the EIA, which investigates and evaluates routine and non‐ routine environmental impacts associated with the development. 1.3. SCOPE OF THE ENVIRONMENTAL STATEMENT An ES is required under the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects Amendment) Regulations 1999 (as amended 2007 and 2010) as the Balloch development will produce in excess of 500 tonnes (approximately 3,750 barrels) per day. The scope of the EIA and resultant ES includes all activities associated with the Balloch development, namely: The drilling of one appraisal/production well and a further two production wells. The first production well will be a sidetrack off the appraisal well; Installation of production and gas lift pipelines and umbilicals (~100m) and cooling spools to connect the wells to the existing Donan DC2 manifold; Modifications to the GPIII and NSP FPSOs; Commissioning of the wells. This ES sets out to assess the implications of any discharges and emissions from the development on the environment. These include additional atmospheric emissions, permitted and accidental discharges to sea and the impacts of noise on marine mammals. In addition, the disturbance to the seabed habitat caused by subsea infrastructure and its potential interaction with fishing activities have been considered. 1.4. LEGISLATIVE OVERVIEW This section provides a brief overview of the current legislation. Appendix A provides a full list of legislation regarding the offshore oil and gas industry.
Balloch Field Development Environmental Statement Section 1 Introduction Offshore environmental control has significantly developed over the past thirty years and is continuing to evolve in response to increasing awareness of potential environmental impacts. Strands of both primary and secondary legislation, voluntary agreement and conditions in consents granted under the petroleum licensing regime and international conventions have all contributed to the current legislative framework. The main controls for new projects are EIAs, which have been a legal requirement for offshore developments since 1998. Current requirements are set out in the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations 1999 (as amended 2007 and 2010), hereafter referred to as the EIA Regulations, and accompanying Guidance Notes for Industry (DECC, 2009). The EIA Regulations require an ES to be submitted and prepared for: Developments which will produce 500 tonnes or more per day of oil or 500,000 cubic meters or more per day of gas; Pipelines of 800 mm diameter and 40 km or more in length. In addition, an ES may be required for developments which are: Less than 40 km from the UK coast line; Within, or less than 10 km from, an SPA or SAC (protected areas); In areas where designated archaeological features are present and may be damaged or disturbed; In areas which are subject to high seasonal environmental sensitivities and/or within herring or sandeel spawning grounds or important fisheries; Involving operations which may significantly impact other users of the sea; Within 10 km of international boundaries where other member states may request to participate in the procedure. Following the submission of the ES, a period of formal public consultation is required under both the ES Regulations and European Directive 2003/35/EC (Public Participation Directive). The EIA needs to consider the impact on the surrounding environment, including any protected areas or sites currently undergoing the process of being designated as protected. These areas have been developed as a consequence of European Directives, in particular the EU Habitats Directive 92/43/EEC and the EU Birds Directive 79/409/EEC (both amended by EU Directive 2006/105/EC), which have been enacted in the UK by the following legislation: The Conservation (Natural Habitats &c) Regulations 1994 (as amended 2012): These regulations transpose the Habitats and Birds Directives into UK law. They apply to land and territorial waters out to 12 nautical miles (nm) from the coast and have been subsequently amended several times. The Conservation of Habitats and Species Regulations 2010 (as amended 2011): These regulations consolidate all the various amendments made to the Conservation (Natural Habitats, &c.) Regulations 1994 in respect of England and Wales. In Scotland the Habitats and Birds Directives are transposed through a combination of the Habitats Regulations 2010 and the 1994 Regulations. The Offshore Marine Conservation (Natural Habitats, &c) Regulations 2007 (as amended 2009, 2010 and 2012). These regulations transpose the Habitats Directive and the Birds Directive into UK law in relation to oil and gas and also the provisions of the Energy Act 2008 relating to carbon capture and storage plans and projects. Offshore Petroleum (Conservation of Habitats) Regulations 2001 (as amended 2007). These regulations implement the requirements of the Habitats Directive for oil and gas activities, the 2007 amendments extend these provisions to UK waters. Until 1999 these Directives applied only to UK territorial waters (i.e.
