Environment Environmental performance Everyone who works for BP Angola Region is responsible for the continuous improvement of our environmental performance Objectives and targets BP Angola is committed to continuous environmental improvement. To help achieve this, we set annual objectives and targets. When setting these objectives, we concentrate on our most significant environmental impacts. We summarize below our performance in 2010 and our targets for 2011. Target setting takes account of risks, legal requirements, and our specific business circumstances. More detailed information on our environmental performance is provided in the performance data table within this report. 2010 performance and 2011 targets All environmental management system plans and procedures updated Dowell Schlumberger audit completed Feasibility study produced to reduce logistics cost associated with waste management Increase wood and metal recycling by 20% from BP facilities Implement Angola SPU 2010 monthly waste dashboard Produce waste handling plan for Discoverer Luanda drill ship Improve waste tracking at Sonils, to reduce non-conformances with waste transfer notice protocols Enhance waste management practices and submit updated waste management plan to Ministry of Petroleum Improve the amount of correct waste segregation offshore Implement a leaks and seeps programme for the FPSO by 4Q 2010 Reduce reportable oil in water exceedances of greater than 60ppm (daily average) Comply with regulatory requirements of Decree 51/04 before start-up of seismic activity Deliver EMS training to Drilling and Completions 22 BP in Angola Sustainability Report 2010 Deploying Remote Operated Vehicle (ROV) Area Target for 2010 Performance Target for 2011 Standards and policies Chemical management Waste management Operational discharges Seismic Awareness Completed or progress in accordance with plan Achieved partially or later than planned: some concerns over ability to deliver Prepare required statutory plans for the DSS rig and PSVM FPSO Secure regulatory approval for license for new rig DSS and PSVM FPSO Enlarge EMS scope to include PSVM FPSO Conduct supplier assurance of chemicals management (D&C) Ensure accurate waste reporting including purchase of digital or mechanical scale for weighing the wooden waste for recycling Ensure compliance with new regulatory requirements of revised Executive Decree 12/05 (if new law is published) — Deliver EMS, waste management, and ISO 14001 training (Sonils base) Deliver EMS training to new rig (DSS) Performance Air emissions Our routine emissions to the atmosphere result primarily from FPSO power generation, drilling and vessel operations. There is also some flaring from the FPSO and our well operations during well testing and clean-up operations. Production operations lead to occasional emissions from venting due to tanker loading. Our policy is for the FPSO at Greater Plutonio to operate without flaring during steady operations. However, there may be intermittent flaring during start-up procedures and when the gas compression facilities are unavailable to allow production to continue from the complex subsea system that cannot be readily stopped and re-started. The emissions from these sources include carbon dioxide, methane, non-methane hydrocarbons, and oxides of nitrogen and sulphur (NOx and SOx). Our emissions to air, the majority of which come from the FPSO, have been tackled principally through the design of the facility and process. Gas compression and reinjection facilities seek to avoid the need to dispose of associated gas to flare. Under normal operations, we have the ability to recover flare gas through a flare recovery system. This excludes flaring required for safe operation of the facility such as during major process upsets. The BP Angola flare policy is designed to manage flaring in day to day operations. Carbon dioxide (CO ² ) is the principal greenhouse gas involved in climate change, and reducing CO ² emissions is therefore a serious concern. Our equity share greenhouse gas emissions totaled 1,162,490 tonnes CO ² equivalent in 2009 and 1,055,204 in 2010. A number of factors contributed to the decrease in emissions, including changes relating to equity share and variations in production, fuel gas use, flaring and drilling activities across the four blocks. Within this total, our equity share GHG emissions from the Greater Plutonio FPSO increased from 349,652 tonnes in 2009 to 396,384 tonnes in 2010, predominantly as a result of increased flare rates, caused by start-up and shut-down operations. Non-greenhouse gas emissions of SOx and NOx decreased from 2009-2010. Lower drilling activity in 2010 resulted in lower diesel usage and consequently lower emissions of SO ² . NOx emissions also declined.
BP Angola’s principal operations are located offshore, more than 100 kilometres from any centres of population. The predictive models we used during the project design phase looked at the potential impact of our operations on air quality onshore. This analysis found that the operations do not have any significant impact on air quality on the Angolan coast. Waste management We manage our waste through operational controls, setting objectives and targets, monitoring and auditing and conducting research or investigations when necessary. Our waste management strategy, implemented through waste management and handling plans at a facility level, seeks to ensure that we meet regulatory requirements and follow acceptable industry practices. We exercise a duty of care over our waste management practices in Angola – using waste transfer notices to document the movement of waste from generation through transfer and handling by approved contractors, through to disposal. We endeavour to implement the waste hierarchy of reducing, re-using and recycling waste from our operations in Angola. The amount of non-hazardous waste disposed decreased from 1,147 tonnes in 2009 to 426 tonnes in 2010, primarily as a result of lower levels of drilling activity in block 31. The amount of hazardous waste disposed also decreased in 2010. Where it is not feasible to implement waste reduction, BP strives to re-use certain waste streams. For example, we are donating waste wood from our operations in support of a local community project. Where re-use is not practical, we aim to recycle wastes. We regularly examine the market to find new options for scrap metal recycling. Water discharges Within BP Angola, we try to manage our wastewater discharges so that we do not adversely impact the quality of the receiving waters. The wastewater streams that we manage include ballast water, bilge, oncethrough cooling water discharges and rain water run-off. We also manage produced water and have the ability to treat and re-inject it into the oil reservoir for reservoir pressure support. We monitor the amount of oil in produced water, and set daily and monthly average targets for reducing these levels. We also monitor and report on the number of oil in water excursions (defined as occasions when we exceed our desired levels for oil in water). We reduced the number of oil in water excursions to 21 in 2010, compared with 48 in 2009. However, the total volume of produced water discharged to the sea has increased since 2008. Losses of primary containment and oil spills There were 15 losses of material from primary containment (LOPC) in our activities in 2009, 14 of which occurred in operations and one during exploration and appraisal activities. Of these LOPC incidents, the quantity of the largest oil spill amounted to approximately 208 litres. In each case, we assessed the actual and potential severity of the loss and developed actions to prevent reoccurrence. There were no LOPC incidents in 2010. Spill preparedness We have been enhancing our oil spill preparedness and response capability following the Gulf of Mexico oil spill. Initiatives have included the development of offshore and coastal environmental and socio-economic maps, integrated into a geographic information system (GIS) database, to identify sensitivities along the Angolan coast where there is potential for oil spill impact. We will be building on this work in collaboration with the Angolan Committee of Exploration & Production Association (ACEPA). We have also updated our oil spill modeling results – examining where oil spilled offshore might reach land, and how long it may take to reach the shore. Noise To mitigate and avoid negative effects from noise on marine fauna, BP has implemented strict noise controls at all its seismic operations. This includes having marine mammal observers on board the sound source vessels, making provision for stopping operations when vulnerable fauna are present in the area and introducing safe operational practices such as soft starts. Monitoring and protecting biodiversity We are collaborating in a research partnership to improve understanding of the deepwater environments of Angola where exploration and production is taking place. The deep-ocean long-term observatory Aerial view of Greater Plutonio FPSO Environment system project, is an initiative involving Sonangol, SSI and representatives from several international universities and scientific institutions, including the Angolan Institute of Fisheries Research. The project aims to measure and monitor deep sea biological communities and oceanographic conditions, understand the pace of recovery from any unforeseen impacts and differentiate between natural and man-made changes. The project uses two sophisticated monitoring platforms positioned in water depths of some 1,400 metres, serviced by remotely operated vehicles. Following initial operational challenges in which the new technology was bedding in, we are now receiving results from the observatory and are building a comprehensive data set that will enable analysis to begin.
