Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 Delivery Team Leaders Are responsible for ensuring that land transfer, site preparation, abandonment and restoration activities, including contractor activities are managed in accordance with the requirements of this Specification. Land management issues addressed in this Specification shall be: identified recorded, as appropriate (refer to Section 2.2.1) reported, as appropriate (refer to Section 2.2..2) In the event that circumstances prevent compliance with this Specification, Delivery Team Leaders shall seek the advice and if necessary, a ‘step-out approval’ from the Document Owner. This approval requires recording subject areas, which do not conform as a non-compliance (refer to the ‘Non Compliance Report Form CP 122 HSE Management System Manual, Part 2 Chapter 6). Corporate Environment Section Is responsible for assisting in the performance of all environmental due diligence surveys performed on PDO assets, including new acquisitions and for ensuring that they are performed in accordance with this specification.. Contractors Contractors are responsible for ensuring that site preparation, abandonment and restoration activities undertaken in the course of carrying out their contractual requirements, are managed in accordance with the requirements of this Specification and reported, where applicable to the Contract Holder. Document Custodian The Document Custodian is responsible for ensuring that this specification is updated as necessary to reflect any changes to Omani legislation, Shell standards and other requirements to which PDO subscribes. 2.4 Performance Monitoring Following restoration, all sites shall be inspected and surveyed to confirm and register the co-ordinates of the restored area for topographical mapping purposes. 2.5 Review and Improvement Any user of this document who encounters a mistake or confusing entry is requested to immediately notify Corporate HSE Manager using the ‘User Feedback Form’ provided in CP 122 HSE Management System Manual, Part 2 Chapter 3. This Specification shall be reviewed every 4 years. However changes to the current version may be made in less than four years as the need arises depending upon the issue of new and relevant environmental legislation and/or major organisational changes in PDO. 2.6 Performance Standards The Concession Agreement is the basic document which governs land transfer between PDO and the Government. The Concession Agreement also stipulates the responsibility of PDO in managing the land. Although there is no specific legislation for site preparation, abandonment and restoration, several MD’s apply indirectly. In particular RD 114/2001 Article 21 stipulates that it is not allowed: Page 8 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC - Revision: 4 Effective: Jan 09 To cut down or uproot trees without a permit. Carry out any activity which leads to desertification or deterioration of the natural environment. Remove stones, soil, etc. from watercourses, beaches and wadis without a permit. PDO’s Policy on Abandonment requires that redundant assets shall be written-off and removed where appropriate and the environment restored to, or as near as reasonable practicable to, its original state in an agreed time frame. The Concession Agreement specifies that all operations shall be carried out in a workmanlike manner in accordance with good oilfield practice, and that the company will take all reasonable measures to close any unproductive well drilled and subsequently abandoned. Individual licences and permits may establish more stringent requirements than those required by this Specification. In these situations, the more stringent requirements shall apply. The following minimum requirements shall apply to all PDO facilities, except those, handed over or offered to the Government in working condition. A risk based corrective action approach shall be taken to all contamination issues in PDOs operation areas. The Shell Global Environmental Standards (GES No. 9: Soil and Groundwater monitoring and Remediation) to which PDO subscribes, requires that all onshore major installations shall be assessed for soil and groundwater contamination. Where soil and/or groundwater contamination has been detected, risk-based mitigation measures shall be demonstrably in place for any necessary control and/or remediation, including control mechanisms to minimise the risk of migration of contaminants off-site. The ultimate goal is that operation activities shall not lead to soil or groundwater contamination and that recovery measures shall be in place to mitigate loss of containment (i.e. spills) and that all potentially impacted sites have been assessed against legal standards or risk-based criteria and continue to be monitored. All sites exceeding risk-based criteria or legal standards have been remediated. PDO has an interest in the following land areas in Oman. 2.7 PDO concession area Pipeline rights of way outside the concession area PDO camp in Ras al Hamra PDO Head office in Mina al Fahal PDOs water supply well area in Al Khod Performance Execution Essentially PDO satisfies these requirements by managing the process in three broad stages, namely: - Land Transfer Site selection and preparation Site abandonment and restoration Site selection and preparation includes: Page 9 Geophysical operations, borrow pits, well locations Fixed and mobile camp sites Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 Roads, pipeline rights of way, plots for facilities and civil construction Airstrips, landfill and landform sites and landfarms. Site abandonment and restoration includes: Site inspection and survey Roads and associated workings Borrow pits, landfill and landform sites Seismic camps and operations Fixed and mobile camps Buildings, airstrips Power transmission systems and electrical services Wells and well sites Process pipework, vessels and instrumentation Structural steel and concrete Flowlines and pipelines Coastal oil storage and export facilities. PDO’s land management objectives in each of the identified land areas are different and are developed to meet the specific requirements of the location. For contaminated sites, quality of soil shall be assessed and managed by applying the following guidance documents: Shell Group (YG) ’Guide to the Risk-Based Management of Potentially Contaminated Land’; Shell Group (YG) ‘Technical Guide to the Investigation of Potentially Contaminated Land’. 2.8 Land Transfer In order to ensure that environmental liabilities are not accumulated by PDO, environmental controls are needed in the following type of land transfer: Acquisition of New Concession Area Relinquishing of Concessions Land transfer from PDO to Contractors Land transfer from Contractors to PDO Land transfer from PDO to third parties Land transfer between PDO departments The type of controls required depend on the nature of the transfer. Essentially all transfers shall be preceded by a due diligence environmental audit. Audits may also include chemical and legal components, but not all transfers will require all three assessments. See Appendix A for checklist for a due diligence audit. 2.8.1 Due Environmental Diligence during Land Transfer Environmental audits should be undertaken prior to a land transfer in order to ensure that no environmental legacies are either passed over to, or accepted by PDO, without full knowledge and agreement by both parties. The scope of the environmental diligence survey may vary based on the: type of transfer, and prior use of the land being transferred. 2.8.2 Legal Assessment Legal assessment associated with land transfers shall consist of: Page 10 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 Land rights of any tenants already on the land. Responsibility of the various parties for restoration of any features, including contaminated sites. All data collected during a legal assessment shall be documented. If the intended land use is likely to result in conflict with the existing tenants and/or the responsibility for restoration of damages is unclear, the legal assessment shall highlight this issue. 2.8.3 Chemical Assessment Chemical assessments associated with land transfers shall consist of a detailed chemical characterisation of the land being transferred. The requirements of the data collection will be determined by the risk based approach adopted in the environmental due diligence survey. 2.8.4 Responsibility for Initiating Assessments The responsibility for initiating the due environmental diligence survey is defined in the table below. Custody Transfer of Land and Due Diligence Type of Land Transfer Person People to be responsible for consulted initiating the audit Acquiring Concessions XD, XEM MSE/2, FLG Relinquishing Concessions XD, XEM MSE2, FLG Land Transfer from PDO to Contractor Asset Manager HSE Advisor, FLG, Area Co-ordinator Land Transfer from Contractor to PDO Land Transfer from PDO to Third parties Land Transfer between Assets Asset Manager Asset HSE Advisor, Area Co-ordinator Asset HSE Advisor, Area Co-ordinator Asset HSE advisor Asset Manager Contract Holder The type of survey and the level of detail are to be decided on a case by case basis. 2.8.5 Responsibility for Conducting Assessments Audits may be conducted by Asset HSE Advisors, PDO’s Corporate Advisors, third party auditors, or a combination of the above. The scope of the audit will depend on the nature of the land being transferred, and the party to which land is being transferred. The typical scope and responsibilities of the audit for audits during various land transfers is presented in the table below.

Petroleum Development Oman LLC 2.9 Revision: 4 Effective: Jan 09 Site Selection and Preparation 2.9.1 Site Selection This shall be carried out in accordance with PDO’s Hazards and Effects Management Programme (refer to CP 122 HSE Management System Manual, Part 2, Chapter 4 and PDO’s Guideline for Environmental Assessment GU 195. Particular attention should be given in sensitive areas, such as nature reserves, aquifer catchments and archeological sites. 2.9.2 Site Preparation 2.9.2.1 General Earthmoving operations shall be personnel and equipment while earthmoving operations have a supervised to ensure adherence environmental damage. conducted to provide sufficient and safe access for minimising environmental effects. In areas where high environmental impact, they shall be closely to procedures and regulations, and minimisation of The location design shall be optimised to minimise the soil to be dug within the field boundaries and the import of soil from outside the field shall be planned so as to minimise disturbance. Where technically acceptable, any soil removed to make the water storage and cuttings pits, shall be used to construct the site, thus reducing the volume of soil to be brought in from borrow pits. Trees shall not be felled or removed without approval from the Ministry. 2.9.2.2 Borrow Pits All borrow pits need approval from the Ministry of Environment and Climate Affairs (ME&CA). For smaller borrow pits (less than 50m X 50m) in PDO’s concession area, this approval can be obtained retrospectively, based on an annual reporting of the location to ME&CA. For borrow pits larger than the stipulated size, permission shall be obtained in advance. Borrow pits will be constructed to industry best practice. The following are the requirements for borrow pits: Borrow pits shall not be excavated deeper than 2 metres. Borrow pits shall not be made closer than 100m from the centre line of a company road, 200m from the centreline of a Government road, or 100m from a facility. Borrow pits shall not be excavated within a 500m radius of a wellhead within a producing field, or within a 250m radius of a wellhead on the perimeter of a field. Borrow pits shall not be excavated within: wadis (where there is a risk of altering existing water courses), in areas used for grazing livestock, or in other areas which would cause a nuisance to local inhabitants. Borrow pits shall not be excavated in vegetated areas, or result in any removal of trees or other natural vegetation. 2.9.2.3 Roads Construction of roads requires approval from ME&CA (and other Ministries in some cases) in order to ensure that environmental sensitivities are taken into account in the Page 12 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 selection of the route. The Asset constructing the road is responsible for obtaining this permit. 2.9.2.4 Pipeline Rights of Way The routing of pipelines also requires approval from ME&CA (and other Ministries in some cases) in order to ensure that environmental sensitivities are taken into account in route selection and contraction. Wadi crossings shall be carried out so as to cause as little change to the existing relief or the flow of shallow aquifers as possible. 2.10 Site Decommissioning 2.10.1 General Requirements Once a project is completed or decision has been made to permanently discontinue operation at a facility, a decommissioning plan shall be prepared. Waste materials generated during site abandonment and restoration shall be disposed of in accordance with PDO’s SP 1009 Waste Management. Hydrocarbon contaminated soil shall be removed from the site. Hydrocarbon contaminated soil in flare, vent, water storage and cuttings pits shall be removed if the content is greater than 1% weight *. * Limits based on industry ‘best practice’. Flare, vent, water storage and cuttings pits with less than 1% weight hydrocarbon content shall be backfilled with a minimum sand cover of 0.6m and contoured to original ground level* All areas of potentially contaminated land shall be assessed using a risk-based contamination assessment framework. 2.10.2 Specific Requirements 2.10.2.1 Roads and Associated Workings Roads that are no longer required for PDO business will not be maintained by PDO. PDO shall only restore abandoned roads, including those that remain at abandoned well sites, upon specific request of the authorities. 2.10.2.2 Landfill Sites All disused landfill sites shall be covered with at least 0.6 metres of clean sand as top cover, and the surface of the site contoured, so that it fits in with the surrounding landscape. The site shall be abandoned with proper markings, on concrete, indicating the nature of the waste disposed off at that location. 2.10.2.3 Landfarms Landfarms where hydrocarbon waste has been treated shall be decommissioned only if the hydrocarbon concentration is no more than 1%. The landfarm shall be abandoned only after a due diligence audit of the site. Page 13 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 2.10.2.4 Borrow Pits o After use, the slopes of borrow pits shall be contoured to a maximum of 30 from the horizontal and all surface irregularities returned to the borrow pit and smoothed off. The intent is that an abandoned borrow pit shall appear no more than a naturally occurring depression in the desert, safe for vehicles and animals. 2.10.2.5 Camps Buildings and associated facilities, including oil storage and fencing, shall be removed. Camp sites shall be restored by smoothing the entire site within one month after vacation of the camp site. Waste pits and sewage pits shall be backfilled and earthwork constructions (e.g. sound deflecting walls) levelled. Compacted areas, such as the access road and the camp pad do not need to be broken up or harrowed. 2.10.2.6 Airstrips Buildings and associated facilities, including oil storage and fencing, shall be removed from airstrips which are permanently abandoned. The main airstrip does not require restoration. 2.10.2.7 Power transmission and electrical services All electrical facilities shall be de-activated prior to abandonment. The surface facilities, cables etc shall be removed. Buried electrical cables etc. may be left in place so long as they do not stick out from the ground. 2.10.2.8 Wells and Well Sites (Exploration, Oil and Gas Production, Water Supply) Suspended well sites shall be reviewed annually, with a documented decision taken for each of them as regards their status in the next year. The review shall include the technical integrity of the wells to ensure that the wells can remain safely suspended. Following the decision to abandon a well, the well shall be plugged and the location restored within 12 months of the decision. Any mass concrete foundations, ground slabs and anchor blocks shall be broken up to a size such that they can be incorporated below original ground level wherever possible and will not cause a problem to earthmoving equipment if the location is excavated in the future. The reinforced concrete-lined well cellar wall shall be broken up to a depth of 500 mm above the bottom of the cellar (but not deeper than the isolated casing stub) and backfilled using rig pad material. Particular care shall be taken when breaking up the cellar to maintain well integrity at all times. After taking into account the location-specific contouring requirements below, excess rig-pad material and broken-up masonry shall be removed. All waste pits at drilling sites shall be investigated for chemical contamination. Parameters to be investigated will depend on the type of chemicals used in the well programme. When sufficient information is not available, a composite toxicity test may be conducted. Once the analysis report is available a risk-based assessment shall be done to identify the most appropriate clean-up requirement and methods. Waste pits shall be backfilled with a top cover of at least 0.6 metres of clean sand and contoured to the level of the original ground level. The entire well location shall then be smoothly contoured to match as closely as possible the original ground level, with a slope no greater than 14.5o (1:4) from the horizontal to allow the safe traverse by vehicles in the future. Care shall be taken such Page 14 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 that during contouring, waste from the pits is not spread over the location. If necessary to avoid spreading waste, the contents of the waste pit shall be excavated, isolated and disposed of in accordance with SP 1009 Waste Management Specification. 2.10.2.9 Coastal Oil Storage If it becomes necessary, coastal storage facilities shall be removed in accordance with PDO’s Engineering Standards. Reinstatement of large rock excavation is not considered to be practicable. A risk-based due diligence survey of the terminal area shall be done as a part of the abandonment. 2.10.2.10 Export facilities Following abandonment, all unused flexible lines and surface export facilities which could interfere with navigation shall be removed entirely. 2.11 Landscape Restoration 2.11.1 General Requirements After the removal of surface facilities, the restoration of the landscape to an adequate standard will primarily involve earthmoving operations. The restored landscape shall be visually similar to adjacent landscape and shall not present a hazard to overland transport. Landscape restoration methods may be undertaken by natural processes or by intervention. The natural processes in the Omani desert which promote restoration, are primarily wind, also diurnal temperature variations and the occasional rainfall and water flow particularly in Wadis. Intervention requirements for landscaping different environmental features are detailed below In almost all cases, vegetation should be allowed to return by natural colonisation. If serious erosion problems are envisaged, the landscaping operation may include seeding or planting of stabilising vegetation. Care shall be taken when landscaping not to cause damage to adjacent areas. 2.11.1.1 Mobile Sand Dunes Windblown sand will gradually cover disturbed areas. Therefore, major earthmoving operations should not normally be used for mobile sand dunes. 2.11.1.2 Fixed or Slow Moving Sand Dunes Excavated or disturbed areas may remain visible for many years on fixed or slow moving sand dunes. Earthmoving should aim to restore a natural profile in these areas. 2.11.1.3 Flat Non-Mobile Desert Excavated or disturbed areas may remain visible for many years on flat desert. Earthmoving should aim to restore a flat profile in these areas. Page 15 Specification for Land Management The controlled version of this CMF Document resides online in Livelink®. Printed copies are UNCONTROLLED. Petroleum Development Oman LLC Revision: 4 Effective: Jan 09 2.11.1.4 Bedrock Plains Major intervention should not normally be used on bedrock plains, except during the removal of surface materials and backfilling of excavations. Excavation scars should be allowed to weather naturally. 2.11.1.5 Boulder Strewn Areas Boulder strewn areas should be profiled by earthmoving to match the surrounding area. 2.11.1.6 Jebel Jebel areas are easily scarred by excavation machinery. cause further damage. Restoration works may Access ramps to jewels shall be removed to prevent their use as unofficial roads, particularly where there are potentially dangerous landforms. Other excavation and construction scars should be left to weather naturally. 2.11.1.7 Wadi Wadi crossings, which have been used as transport or pipeline routes, shall be profiled by earthmoving to restore their natural profile. The natural landscape of the wadi will usually be restored following significant rainfall and wadi flow. 2.11.1.8 Sabkha Operations that cause scarring of the surface crust should not be restored by earthmoving. The alternative flooding and drying of sabkha will gradually restore the natural profile to the surface crust.
