9 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 1 1 INTRODUCTION 1.1 SCOPE AND OBJECTIVES This (EMP) has been prepared as part of the Environmental Impact Assessment (EIA) for Shell s proposed Deep Water Exploration Well Drilling in Petroleum Exploration Licence 39 (PEL 39) off the coast of southern Namibia. The significance of residual impacts are contingent on Shell fully implementing the mitigation measures and on the effectiveness and efficacy of the mitigation measures. The objectives of the EMP are to: fulfil the of Namibian EIA legislation and international Conventions; be consistent with oil and gas industry good practices and Shell s own project standards; identify potential impacts and outline the appropriate mitigation options to ensure that impacts are minimised, after first establishing whether impacts cannot be avoided; provide an implementation mechanism for mitigation measures and commitments identified in the EIA Report; establish a monitoring programme and record-keeping protocol against which Shell and its contractor s/sub-contractor s performance can be measured and to allow for corrective actions or improvements to be implemented when needed; and provide protocols for dealing with unforeseen circumstances such as unplanned events or ineffective mitigation measures. 1.2 SUPPORTING DOCUMENTATION The additional management plans, which will be prepared by Shell prior to the drilling date, include: Oil Spill Response Plan and Emergency Response Plan: These plans will include all res and action required to manage Tier 1, 2 and 3 spills and any impact on the environment, including the Namibian and any neighbouring coastlines. Shipboard Oil Pollution Emergency Plan (SOPEP): Regulation 37 of MARPOL Annex I requires that all ships of 400 gross tonnage and above carry an approved SOPEP. The purpose of a SOPEP is to assist personnel in dealing with unexpected discharge of oil, to set in motion the necessary actions to stop or minimise the discharge, and to mitigate its effects on the marine environment. Ballast Water Management Plan: All ships engaged in international traffic are required to manage their ballast water and sediments to a certain standard, according to a ship-specific ballast water management plan. This plan deals with the ballast water management system on each of the project s, including how it operates and procedures for monitoring and reporting. Waste Management Plan: This plan establishes procedures for the storage, collection and disposal of waste, including liquid and solid waste and hazardous and non-hazardous wastes. Well Control Contingency Plan: This plan is a specific response guide used in the case of well control emergency. The requirement for each of these plans is referred to in relevant sections of the EMP tables.

11 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 3 2 SENSITIVE RECEPTORS An overview of the key sensitivities in the study area and implications for the project is provided below and presented in Figure 2-1. Receptor/Vari able Implications for proposed project 1. Bio-physical considerations Tripp Seamount Namibian Islands Marine Protected Area (NIMPA), including offshore islands and seal/seabird colonies Tripp Seamount is a geological feature located approximately 50 km to the south-east of the area of interest. Seamounts typically complex benthic ecosystems with higher productivity, which in turn enhance foraging opportunities for many other predators, serving as mid-ocean focal points for a variety of pelagic species with large ranges (turtles, tunas and billfish, pelagic sharks, cetaceans and pelagic seabirds) that may migrate large distances in search of food or may only congregate on seamounts at certain times. Aggregations of albacore tuna are known to occur in the vicinity of the Tripp Seamount and are targeted by the tuna pole fishery. The drill cuttings deposition footprint extends up to 7 km from the drill site, while drilling noise is predicted to return back to ambient levels within 32 km of the drill site. In addition, the dominant wind and current direction would result in discharges moving mainly in a north-westerly away from the seamount. Due to the distance between the area of interest and the seamount and the dominant winds and currents, impacts from operational discharges and noise are unlikely to impact marine fauna and fishing at Tripp Seamount. Thus, there are no implications for the project. The NIMPA was established for the purpose of protecting sensitive ecosystems and breeding and foraging areas for seabirds and marine mammals, as well as protecting important spawning and nursery grounds for fish and other marine res (such as rock lobster). It comprises the coastal strip extending from Hollamsbird Island (24º38 S) in the north to Chamais Bay (27º57 S) in the south. It is km 2 in extent, has an average width of 30 km and includes 16 specified offshore islands, islets and rocks. Atlas Bay, Wolf Bay and Long Islands (near Lüderitz) together represent the largest breeding concentration of seals in Namibia. Further colonies are located at van Reenen Bay and Bakers Bay. These islands also provide a vital breeding habitat for seabirds, some of which are threatened (e.g. African penguin, bank cormorants, crowned cormorants, oystercatchers and gannets). Southern right whale calving and nursing activities are known to occur in Elizabeth Bay (approximately 8 km south-east of a direct flight path between the Lüderitz airport and the area of interest) and Hottentot Bay (approximately 60 km north of Lüderitz, well to the north of a direct flight path). The months of main calving and nursing activities include June to September. Helicopters and s operating between Lüderitz and the drilling unit would be required to travel over/through the NIMPA. Helicopter would need to avoid offshore islands, seal/bird colonies and maintain an altitude of at least m within the NIMPA. 2. Socio-economic considerations Fishing Tourism Fishing plays a significant role in providing livelihoods and income for communities living in and around Walvis Bay and Lüderitz. There is thus a need to notify key sectors regarding the drilling programme and exclusion zone around the drilling unit. The large pelagic long-line sector is the only sector that overlaps with the area of interest. The drilling unit would need to maintain the 500 m safety zone around the unit. Support s on route to and from Lüderitz would also need to avoid other fishing s that are limited in their manoeuvrability. There is also a need to manage impacts to the marine environment, especially of un-planned events such as oil spills. Given that tourism in Lüderitz and Walvis Bay is largely centred on ocean-based experiences, the project would have to place significant emphasis on mitigating the impacts associsated with unplanned events such as oil spills. The relatively small size of Lüderitz may require management of accommodation for project personnel in the peak tourist seasons in order that adequate accommodation is still available for other tourists.

13 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 5 3 PROJECT CONTROLS AND MITIGATION MEASURES The mitigation hierarchy, as specified in IFC Standard 1, is widely regarded as a good practice approach to managing risks and is based on a hierarchy of decisions and measures, as described in Table 3-1. This is aimed at ensuring that wherever possible potential impacts are mitigated at rather than mitigated through restoration after the impact has occurred. measures, identified as part of the EIA process, is aimed at first preventing, then minimising or managing significant negative impacts to as low as reasonably practicable (ALARP) and optimising any potential benefits of the proposed project. measures referred to as project controls are integrated into the project design and standard operating procedures (refer to Box 3-1 for the project controls). These measures require proactive checking and verification prior to any project activities in-country. The additional mitigation measures identified by the specialist scientists and EIA Team have been integrated into this EMP and will be integrated into the contract documents for the drilling, drilling services, logistics and other. The specific management commitments (project controls and mitigation measures) that will be implemented are presented in Section 10. Table 3-1: The mitigation hierarchy at Source Abate on Site Abate Offsite/at Receptor Repair or Restore Compensate or Offset ing or reducing at is essentially designing the Project so that a feature causing an impact is designed out (e.g. a waste stream is eliminated). This involves adding something to the basic design or procedures to abate the impact (often called end-of-pipe ) or altered (e.g. reduced waste volume) and is referred to as minimisation Pollution controls fall within this category. If an impact cannot be abated on-site then measures can be implemented off-site an example of this in the case of the drilling programme would be disposing of waste generated on-board at a proper waste facility onshore. Measures may also be taken to protect the receptor. Some impacts involve unavoidable damage to a re, e.g. shoreline pollution arising from an oil spill. Repair essentially involves restoration and reinstatement type measures, such as clean-up of the shoreline. Where other mitigation approaches are not possible or fully effective, then compensation, in some measure, for loss, damage and general intrusion might be appropriate. An example could be compensation for loss of earnings if fisheries were to be permanently impacted by a Project activity.

14 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 6 Box 3-1: Project Controls Project Controls are the physical or procedural controls that are planned as part of the project (i.e. they are embedded into the project design). Shell s offshore exploration projects are carried out within a framework of national regulations, international conventions, corporate policies and procedures, and recognised third party guidelines, all of which have different applications, remits, and implications. Shell has developed Project Controls (or Standards) for offshore drilling and those applicable to this project are listed below. 1. Emissions and discharges Project s comply with the emission criteria within MARPOL 73/78 Annex VI, which prohibits the: > deliberate emission of Ozone Depleting Substances; and > incineration of certain products, such as contaminated packaging materials and polychlorinated biphenyls (PCBs). The drilling unit would use marine diesel that has a maximum sulphur content of 0.1%. The following is specified for Ozone Depleting Substances: > Identification of all Ozone Depleting Substances and maintenance of an inventory until Ozone Depleting Substances are eliminated. > Elimination of halons and hard chlorofluorocarbons (HCFCs) in all operations by end-of-year 2010 and HCFCs by beginning-of-year > Removal of Ozone Depleting Substances from Non-Sealed Systems. > Provision of controls to prevent the loss of Ozone Depleting Substances. > Provision of controls for the recovery and destruction of Ozone Depleting Substances. > the transfer of Ozone Depleting Substances to third parties for re-use. Where permitted by legislation, in-company transfers and transfer to Halon banks are permitted. > Provision of controls to ensure that new installations are not fitted with HCFCs. > Provision of terms that comply with the above in contracts for the purchase, service or disposal of equipment or refrigerant that contains Ozone Depleting Substances. > Ensuring people are aware of equipment that contains Ozone Depleting Substances and the controls required before they perform work that could release these substances. > Application of the Permit to Work system in order to control work on, or disposal of, equipment that contains Ozone Depleting Substance in line with the above. Sewage and grey water discharges from s are regulated by MARPOL 73/78 Annex IV, which specifies the following: > Vessels must have a valid International Sewage Pollution Prevention Certificate. > Vessels must have an onboard sewage treatment plant providing primary settling, chlorination and dechlorination before discharge of treated effluent. > Discharge of sewage beyond 12 nm requires no treatment. However, sewage effluent must not produce visible floating solids in, nor cause the discolouration of, the surrounding water. > Sewage must be comminuted and disinfected for discharges between 3 nm (± 6 km) and 12 nm (± 22 km) from the coast. This would require an onboard sewage treatment plant or a sewage comminuting and disinfecting system. > Disposal of sewage originating from holding tanks must be discharged at a moderate rate while the ship is proceeding on route at a speed not less than 4 knots. Sewage would be treated using a marine sanitation device to produce an effluent with: > a biological oxygen demand (BOD) of <25 mg l -1 (if the treatment plant was installed after 1/1/2010) or <50 mg l -1 (if installed before this date); > minimal residual chlorine concentration of 1.0 mg l -1 ; and > no visible floating solids or oil and grease. The discharge of biodegradable wastes from s is regulated by MARPOL 73/78 Annex V, which stipulates that: > No disposal to occur within 3 nm (± 5.5 km) of the coast. > Disposal between 3 nm (± 5.5 km) and 12 nm (± 22 km) needs to be comminuted to particle sizes smaller than 25 mm.

15 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 7 Box 3-1 cont. 1. Emissions and discharges (cont.) Discharges of water (deck drainage, bilge and mud pit wash residue) to the marine environment are regulated by MARPOL 73/78 Annex I, which stipulates that s must have: > A Shipboard Oil Pollution Emergency Plan (SOPEP). > A valid International Oil Pollution Prevention Certificate, as required by class. > Equipment for the control of oil discharge from machinery space bilges and oil fuel tanks, e.g. oil separating/filtering equipment and oil content meter. Oil in water concentration must be less than 15 ppm prior to discharge overboard. > Oil residue holding tanks. > Oil discharge monitoring and control system. Ballast water discharge would comply with the of the IMO s 2004 International Convention for the Control and Management of Ships Ballast Water and Sediments, including: > the implementation of a Ballast Water Management Plan; and > conducting such exchange at least 200 nm (± 370 km) from the nearest land and in water of at least 200 m depth. Where this is not feasible, the exchange should be as far from the nearest land as possible, and in all cases a minimum of 50 nm (± 93 km) from the nearest land and preferably in water at least 200 m in depth. The discharge of drilling fluids and cuttings would comply with the following standards: > Discharge of cuttings via a caisson at greater than 15 m water depth; > Discharge of cuttings only in water depths greater than 30 m; > Treatment of cuttings to reduce the: Oil content to 6.9% or less of dry cutting weight; PAH to less than 0.001; Hg to less than 1 mg/kg; and Cd to less than 3 mg/kg. Cement returns would be monitored and pumping would be terminated if returns are observed on the seafloor. 2. Social A Social Plan, which includes a Social Investment Strategy, will be established and maintained. Stakeholder engagement will be undertaken in order to: > inform key stakeholders of project progress; > communicate a procedure to receive, track and respond to questions and complaints; and > seek input on the social impacts of business activities, and on mitigation or enhancement measures. 3. Supplier Principles for and suppliers Business integrity: > Contractors and suppliers are required to comply with all applicable laws and regulations. > Contractors and suppliers should not tolerate, permit or engage in bribery, corruption or unethical practices. > Contractors and suppliers are to fair competition. > Conflicts of interest are avoided. Health, Safety, Security and Environment: > Contractors and suppliers must be committed to protect the environment in compliance with all applicable environmental laws and regulations. > Contractors and suppliers must use energy and natural res efficiently. > Contractors and suppliers must minimise waste, emissions and discharge of their operations, products and services.

16 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 8 Box 3-1 cont. 3. Supplier Principles for and suppliers (cont.) Social performance: > Contractors and suppliers are to respect their neighbours and contribute to the communities in which they operate. Labour and human rights: > Contractors and suppliers are to conduct their activities in a manner that respects human rights as set out in the United Nations Universal Declaration of Human Rights and the core conventions of the International Labour Organisation. Contractors and suppliers should: Not use child labour; Not use forced, prison or compulsory labour; Comply with all applicable laws and regulations on freedom of association and collective bargaining; Not tolerate discrimination, harassment or retaliation and should provide a safe, secure and healthy workplace; and Provide wages and benefits that meet or exceed the national legal standards and comply with all applicable laws and regulations on working hours. 4. Oil spills Design and technical integrity: > Well design would be undertaken in accordance with Shell design manuals and standards, which includes for well engineering, completion and well intervention personnel. Multiple well casings: > Casings would be designed to withstand a variety of forces, such as collapse, burst or tensile failure, as well as chemically aggressive brines; and > Casings would be run to prevent caving-in of upper formations, provide strong foundations for high density fluids, isolate zones of fluid loss or different pressure gradients and prevent fluid loss into or contamination of production zones. Wellbore pressure: > Subsurface pressures above and within the hydrocarbon-bearing strata would be controlled by the use of weighted drilling mud; and > The hydrostatic pressure of the drilling mud in the well would be adjusted by adding weighting agents such as barites to ensure that it is greater than the formation pressure to prevent the undesired influx of fluids into the wellbore (known as a kick ); and > Pressure monitoring would be undertaken during drilling to ensure that kicks are avoided or managed to prevent escalation into a blowout. BOP stack: > BOP stacks would be used to control the pressure of a well through mechanical devices designed to rapidly seal the well (or shut in ) in an emergency. Competent staff: > Shell has competent people who would design the well and monitor drilling. Testing and certification: > Safety critical equipment would be subject to testing and certification to ensure that it meets design specifications. The well design, drilling, preparation and completion plans would go through several stages of review involving experts from Shell and the drilling contractor prior to the commencement of drilling operations. > As standard practice, an Oil Spill Response Plan would be prepared and put in place at all times during the drilling operation. There are three principal components underpinning an Oil Spill Response Plan: Crisis management (Emergency Command and Control Management). Spill response, containment and clean-up. Well control.

17 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 9 Box 3-1 cont. 4. Oil spills (cont.) Emergency command and control management: > Emergency command and control management arrangements range from the On-scene Commander, normally at the of the incident, to the main Emergency Control Centre Incident Commander who takes over control. As each level is activated, the level of response would equally escalate. Well control: > Whilst the Oil Spill Response Plan defines the approach and strategy required to manage the containment, removal and clean up following a major spill, the well control process is focussed on stopping the of the leak. > A Well Control Contingency Plan would be put in place for each well. Cap and containment equipment: > If the BOP does not successfully shut off the flow from the well, the drilling rig would disconnect and move away from the well site while crews mobilise a capping system. The capping system would be lowered into place from its barge and connected to the top of the BOP to stop the flow of oil or gas. Shell is a member of Oil Spill Response Limited (OSRL), which operates advanced well intervention and capping equipment from Saldanha Bay for deployment in the event of a subsea well control incident. All of Shell s wells are designed to allow for capping. Containment and clean-up equipment: > Project s would be equipped with appropriate Tier 1 spill containment and clean-up equipment, e.g. booms, dispersants and absorbent materials. > All relevant crews would be trained in spill clean-up equipment use and routine spill clean-up exercises. Logistical arrangements for the integration of additional would be in place (e.g. from OSRL). 4 ROLES AND RESPONSIBILITIES The project would have dedicated competent personnel that would manage and oversee the Environmental, Health and Safety (EHS) aspects over the project lifecycle. Shell would, however, retain the primary responsibility for meeting environmental commitments throughout the project life span. The key environmental management roles and responsibilities are presented in Figure 4-1 and Box 4-1.

20 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 12 5 TRAINING, AWARENESS AND COMPETENCY Shell would identify, plan, monitor and record training needs for personnel whose work may have a significant adverse impact upon the environment. Shell recognises that it is important that employees at all levels are aware of Shell s HSSE policy, potential impacts of their activities, and roles and responsibilities in achieving conformance with the policy and procedures. The personnel with responsibilities in specific environmental practices will be adequately trained to ensure effective implementation of the works instructions and procedures for which they have responsibilities. This training would include awareness and competency with respect to: General awareness relating to deep water exploration well drilling activities, including environmental and social impacts that could potentially arise from project activities; Legal in relation to environmental performance; Necessity of conforming to the of the Environmental Clearance Certificate and EMP, including reporting (i.e. such as incident reporting); Activity-specific training (i.e. waste management practices); Roles and responsibilities to achieve compliance, including change management and emergency response. Training would take cognisance of the level of education, designation and language preferences of the personnel. Shell would also require that each of the appointed institute training programmes for its personnel. Each contractor will be responsible for site HSSE awareness training for personnel working on the project and for identification of any additional training to maintain required competency levels. The contractor training programme will be subject to approval by Shell and it will be audited to ensure that: training programs are adequate; all personnel requiring training have been trained; and competency is being verified. 6 COMPLIANCE VERIFICATION AND CORRECTIVE ACTIONS Inspections, monitoring and auditing will be undertaken to confirm appropriate implementation of the EMP, as well as the effectiveness of mitigation measures. Corrective actions include those intended to improve performance, non-compliances and non-conformances. 6.1 INSPECTION Contractors will be required to conduct daily and weekly HSSE inspections in an effort to monitor compliance and implement conditions stipulated in this EMP.

The audit data will include the Contractor s monitoring and inspection records. The audit will include amongst other things, checking: completeness of HSSE documentation, including planning documents and inspection records; conformance with monitoring ; efficacy of activities to address any non-conformance with monitoring ; and training activities and. Findings would be documented in monthly audit reports, which will be submitted to Shell s Operations Manager / Well Delivery Manager for action and follow-up INDEPENDENT CLOSE-OUT EMP COMPLIANCE AUDIT An independent close-out EMP compliance audit will also be conducted prior to demobilisation completion. This report will, amongst other things, outline the implementation of the mitigation measures and compliance levels with achieving the performance objectives as detailed in the EMP. 6.4 CORRECTIVE ACTIONS The Contractor s HSSE staff will implement a formal non-compliance and corrective action tracking procedure for investigating cause and identifying corrective actions in response to accidents, environmental and/or social non-compliances. Where corrective actions are deemed necessary, specific measures will be developed, with designated responsibility and, and implemented. In this way, continuous improvement in performance would be achieved. The Contractor s HSSE staff will be responsible for keeping records of corrective actions and for overseeing the modification of environmental or social protection procedures and/or training programmes to avoid repetition of non-conformances and non-compliances.

24 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 16 7 MANAGEMENT OF CHANGE The development and implementation of the EMP is an ongoing process that is iterative in nature. This document must thus be seen as a living document and amendments may need to be implemented during the course of the project. Typical changes that can affect the EMP include: A material project design change that occurs after the EMP has been compiled and approved. Changes in the feasibility/availability of specific mitigation measures. Personnel changes on the project. This document is thus the first version of the EMP. Certain aspects of this document may be expanded/made more specific during the detailed design stage to ensure, firstly, that it includes all conditions of approval and, secondly, that it addresses all issues related to the detailed design. The following scenarios may apply: Minor changes to the EMP that are not considered to be materially significant departures or material to the findings of the EIA can be made and implemented by Shell s HSSE Manager. Any significant revisions to the EMP document that are considered to be materially significant departures from the mitigation measures listed in the EIA must be communicated to MME and MET before the amended EMP is implemented. Any changes to the project scope that are considered to be material to the findings of the EIA must be communicated to MME and MET. A register of changes to the EMP will be kept with an approval sign off sheet. 8 COMMUNICATION Channels of communication will be established between Shell, the contractor(s) and external stakeholders. The Shell Operations Manager / Well Delivery Manager will establish and maintain procedures for: Internal communication between the various levels and functions of the project staff organisation; and Receiving, documenting and responding to relevant communication from external interested parties. A grievance procedure will be established and maintained by the Shell Windhoek Office to record any complaints or comments received from the public during the drilling programme. The grievance procedure will be underpinned by the following principles and commitments: Disseminate key information to directly impacted stakeholders; Seek to resolve all grievances timeously; and Maintain full written records of each grievance case and the associated process of resolution and outcome. The responsibility for responding to grievances will lie with Shell. 9 DOCUMENT CONTROL AND REPORTING 9.1 DOCUMENTATION Shell will control HSSE documentation, including project licences, approvals, management plans, associated procedures, checklists, forms and reports, through a formal procedure. The document control procedure will

25 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 17 describe the processes that the project will employ for official communication of both hardcopy and electronic documents and the requirement for electronic filing, document tracking and version control numbers. The Contractor(s) will be required to develop a system for maintaining and controlling its own HSSE documentation and describe these systems in their respective HSSE plans. 9.2 INCIDENT REPORTING Following any HSSE incidents, Shell would conduct an incident investigation and prepare a report detailing the events and corrective and preventative measures implemented as a result. All incidents where local regulatory standards are exceeded will be reported to MET and MME. 9.3 EMP COMPLIANCE REPORT Shell will submit a EMP compliance report to MME. Amongst other things, this report will outline the implementation of the mitigation measures and compliance levels with achieving the performance objectives as detailed in the EMP. 10 ENVIRONMENTAL MANAGEMENT PLAN This section details the specific management commitments that will be implemented to prevent, minimise or manage significant negative impacts and optimise and maximise any potential benefits of the project. These commitments are presented for the three project phases, namely: Mobilisation Phase Section Operation Phase Section Decommissioning Phase Section This EMP is structured in the following manner so that the mitigation measures have a clear and logical context within which they are designed, implemented, monitored and evaluated: Activities; Aspects; ; s; Indicators; Targets; ; ; ; Timing; and Record Keeping Requirements. Refer to Box 10-1 for the content details.

26 SLR Environmental Consulting (Namibia) (Pty) Ltd Page 18 Box 10-1: EMP Structure Activities Aspects s Indicators Targets Timing Record Keeping Requirements Structure of the EMP Description Activities are the physical activities that occur as a result of a project. These would be all the activities that are required in mobilising, ing, operating and demobilising an offshore drilling unit. Activities include the physical action or presence of the drilling unit and platform supply s associated with the drilling campaign; the operation of the drilling unit, associated s and helicopter operation; and the actions of Project staff. Environmental and social aspects are defined as an element of an organisation s activities, products or services that can interact with the environment e.g. atmospheric emissions, underwater noise levels or discharge of waste to sea. A receptor is considered to be someone or something that could be influenced by the Project, including local communities, water res, air quality, ecological habitats or species, or tourism. The importance/sensitivity of a receptor has been defined for the Project taking into account such matters as its local, regional, national or international designation, its importance to the local or wider community, its ecosystem function or its economic value. The assessment of the sensitivity of human receptors, for example a household, community or wider social group, has taken into account their likely response to the change and their ability to adapt to and manage the effects of the impact. Every environmental management requirement must be translated into an objective, namely an outcome that is to be achieved. This is not to say that every requirement must be expressed as an objective, but can be combined as appropriate into single objectives. For every objective defined, a performance indicator(s) must be determined that will serve as an unbiased measure of the degree to which the objective is being met. Indicators must be measurable in some form or other. An important consideration here is the identification of leading and lagging indicators. For every indicator a performance target must be specified. If the target is met then the objective will have been deemed to be met, but if the target is not achieved then suitable corrective action must be defined and implemented so as to ensure that the performance is improved to the point that the target is met and the performance is sustained. A key component of the EIA process is to explore practical ways of avoiding or reducing potentially significant impacts of the proposed drilling programme. These are commonly referred to as mitigation measures and are incorporated into the project as part of the EMP. is aimed at preventing, minimising or managing significant negative impacts to as low as reasonably practicable (ALARP) and optimising and maximising any potential benefits of the proposed project. The approach taken to identifying and incorporating mitigation measures into the project is based on arrange of hierarchical options which are listed in sequential order of priority: ; Minimise; Restore / rehabilitate; Offset; and Compensate. Defining who is responsible for the implementation of the mitigation. Timing refers to the schedule. The can be specified in terms of a specific date or relative to other actions (i.e. before project mobilisation, or after well spudding, as examples). must be defined, whereby the organisation responsible for implementing the action/s is given a prescribed reporting mechanism, limited as far as possible to documents plans, correspondence, records, registers, etc.
