5 CONCEPTUAL CONSERVATION AND RECLAMATION PLAN 5.1 INTRODUCTION This section presents the conceptual Conservation and Reclamation (C&R) Plan for the Project and includes information relating to Pengrowth s development plan and subsequent reclamation of the Lindbergh SAGD Project. Based on discussions with stakeholders and ASRD, the desired end land use for reclaimed disturbances within this area is suitable grazing land for livestock (improved pasture). This conceptual C&R Plan outlines the procedures Pengrowth will use to ensure that the reclaimed landscapes, soils and vegetation communities provide a suitable habitat for this desired end land use. 5.2 PROJECT The Project includes lands subject to direct disturbance from development of the Project. The Project life will be approximately 25 years (including construction, operation and reclamation) with production beginning in late 2013. The Project disturbance footprint is a total of 149.8 ha. Pengrowth has provided two reports that address reclamation, a conceptual C&R Plan and a detailed pre-disturbance assessment on applicable Project components that will be included in the EPEA approval. The detailed pre-disturbance assessment has been completed in compliance with AEW s Guidelines for Submission of a Pre-Disturbance Assessment (PDA) and Conservation and Reclamation Plan (AENV 2009b) (PDA/C&R Plan). Table 5.2-1 lists all Project components that have been addressed in the conceptual C&R plan and those addressed in the PDA/C&R Plan. Figure 5.2-1 displays the Project footprint and components addressed in the PDA/C&R Plan. December 2011 Section 5-1

facility development, well pads, roadways, pipelines, and other landscape alterations will be constructed to be geo-technically stable; construction and operational activities and subsequent interim reclamation will be designed with final reclamation and end land use objectives in mind; reclamation is designed to create a landscape that is self-sustaining and capable of supporting soils and vegetation processes suitable for the desired end land uses with no subsequent management input required; following soil placement or decompaction, vegetation communities will establish and will be capable of ecological succession processes similar to those found within the region for similar end land uses; on those localized sites that are sensitive to erosion (i.e., steeper erodible slopes, coarse textured soils, or disturbances immediately adjacent to watercourses), watershed protection will take priority over other vegetation objectives; water discharges during development and following reclamation will be managed to provide an acceptable level of input that flow into natural watersheds; mitigation and monitoring post reclamation will address issues related to soil, landscape and vegetation; and assessment of reclaimed lands will be completed once site monitoring indicates reclaimed lands and vegetation communities are expected to meet the criteria for certification. 5.4 VEGETATION REMOVAL Pengrowth will salvage merchantable timber in compliance with regulatory requirements. Prior to timber salvage Pengrowth will address the following: rare plants; buffer zones associated with riparian habitat and water courses; and migratory birds (Migratory Birds Convention Act). Upon completion of harvesting merchantable timber, clearing of woody debris will commence. Slashing, degrubbing, clearing and any other means of physical woody debris removal will be conducted to preserve the integrity and quality of the soil. Care will be taken to remove as much woody debris as possible before soil salvage commences. Woody debris disposal will be handled in consultation with ASRD. Woody debris will either be mulched or burned depending on site conditions; in accordance with regulatory requirements. If some woody debris is mulched, it will be spread to a maximum thickness of 5 cm or less over the ground surface as per ASRD Directive 2009-1 (ASRD 2009). December 2011 Section 5-3

5.5 FINAL RECLAMATION The Project reclamation program will include the following procedures to reclaim to a capability suitable for the desired end land use: prior to construction record inventory of pre-disturbance land capabilities and estimate expected reclaimed capabilities based on desired end land uses; meeting with ASRD prior to commencing reclamation activities, to confirm final land use and reclamation procedures that are planned; removal of facilities; remediation of contaminated areas (ongoing throughout operations as well as at decommissioning); completion of appropriate reclamation of organic landscapes as per the end land use objectives; ripping well pads, roadways, and facility pad areas, as required, to alleviate surface compaction; recontouring and re-establishment of natural drainage patterns across disturbed lands; placing salvaged topsoil (litter and mineral A horizons) over the disturbed area with replacement depths similar to what existed prior to development; completion of re-vegetation activities on all reclaimed lands; monitoring and maintenance activities following reclamation in order to assess reclamation success and identify areas of concern; and post-reclamation site assessment to determine the status of the site prior to applying for a reclamation certificate. 5.6 SOIL RESOURCES An inventory of soil resources for the Project has been conducted by MEMS (2011), Soil and Terrain Baseline Assessment. The Baseline Soil and Terrain Assessment for the Project details pre-disturbance soil and landscape conditions and provides interpretation of the soil resources available in the Project footprint. A total of 15 map units (one map unit describes disturbed lands) were used to describe the soils located in the Project footprint. Table 5.6-1 presents the soil map units, soil thickness and volumes of topsoil and organic soil found within each component of the Project footprint. The soil map units are shown on Figure 5.6-1. Detailed map unit summaries for all PDA components are also provided in the PDA/C&R Plan (Appendix 3). December 2011 Section 5-4

Soil thicknesses for PDA components are detailed in Appendix 3. 2 ZDL soils information/estimates taken from immediately adjacent soil map units. Topsoil values are assigned to the ZDL in these instances as the area was mapped as disturbed (trees cleared and possible evidence of disturbed soil), however, soil material is likely either stockpiled adjacent the disturbance or has not been salvaged. This soil material will need to be salvaged/relocated prior to construction. 3 Material volumes estimated from stockpiles adjacent to noted ZDL. 4 Due to rounding of values, component totals may not equal the sum of the individual values presented in the table. 5.7 SOIL SALVAGE Topsoil is defined by AEW in various operating approvals for in situ oil sands projects as the undisturbed soil profile comprised of the following (if present): organic horizons as defined in the Canadian System of Soil Classification, 3rd Edition (Soil Classification Working Group (SCWG) 1998); mineral A horizons (upland soils) rated as good, fair or poor, as described in the Soil Quality Criteria Relative to Disturbance and Reclamation (Soil Quality Working Group (SQWG) 1987); and the replaced topsoil layer in a reclaimed soil. Subsoil is defined by AEW as the layer of soil directly below the topsoil layer and consist of all B horizons defined in the CSSC and rated as good, fair, or poor, as described in the Quality Criteria Relative to Disturbance and Reclamation (SQWG1987) (AENV 2010). AEW requires December 2011 Section 5-6

subsoil material (to a maximum depth of 30 cm) be salvaged from the CPF. This salvaged subsoil will stockpiled separately from the topsoil material. Shallow organic soil is defined by AENV as a surface organic horizon that is <40 cm in depth and deep organic soil as having a surface organic horizon >40 cm in depth. Pengrowth plans to salvage topsoil material for the Project as follows: mineral topsoil and shallow organic soil (<40 cm of organic material) areas will be salvaged; on areas of deep organic soil where pad materials will utilized to build up disturbance areas prior to construction, Pengrowth will not salvage organic soil; soil salvage operations will be suspended in high winds or wet conditions; if topsoil or subsoil material is salvaged during frozen soil conditions Pengrowth will utilize equipment to loosen and break up the frozen soil prior to commencing with salvage activities; and topsoil will not be used for grading, berming or any other construction activities. Pengrowth will salvage a maximum of 30 cm of suitable subsoil material from the CPF for replacement at reclamation. Landscapes within the Project that have organic soil thicknesses >40 cm will not be salvaged. These areas will be built up by placing geogrid and clay fill over the organic material. Appropriate procedures will be based on site specific characteristics and best construction practices. Sufficient soil volumes of suitable soil material will be salvaged and replaced for reclaimed areas to support re-vegetation activities, allow ecological succession and achieve land capability appropriate for the desired end land uses. There are eight distinct footprint components that will have unique soil salvage requirements: Access / Pipe corridors main access, infield access, and pipe corridors; Borrow pits (1-4); Pipeline re-routing & Source water line; Soil storage areas (1-9); Operations, Construction and Supervisor s camp; Well pads (4); CPF; and Remote sumps (2). December 2011 Section 5-7

General soil salvage practices for each distinct component are provided in Sections 5.7.1 to 5.7.8. The material balance for the soil resources is in Table 5.11-1. 5.7.1 ACCESS / PIPELINE CORRIDORS The infield roads and corridors (12.2 ha) include the access to the Construction and Operations camp, well pads and borrow pits (1-3) as well as above ground pipelines and powerlines. A total of 7.3 ha of the infield roads and corridors are considered upland and 4.8 ha are considered to be deep organic soils. Figure 5.7-1 displays the location of upland and organic soils within the Project footprint. The main access corridor (access to the CPF and Operations camp) contains 19.1 ha of upland soils and disturbed lands and 0.3 ha of deep organics. For all access corridors upland soils will be salvaged by pushing the top soil material to the edge of the right of way, out of the way of construction activities. This topsoil material will be stored on the edge of the right of way or spread along the ditches after construction is complete and seeded to establish vegetative cover. Excess soil material will be stored in a windrow type stockpile on the edge of the right of way and seeded. No salvage of deep organic soil is planned. Deep organic areas will be padded over using fill material. Infield Roads / Corridors (12.2 ha) Planned Salvage: upland topsoil (7.3 ha) = 18,642 m 3 organic material (4.8 ha) = 0 m 3 Available Organics organic (4.8 ha) - total available = 70,200 m 3 Main Access / Corridors (19.4) Planned Salvage: upland topsoil (19.1 ha) = 36,044 m 3 organic material (0.3 ha) = 0 m 3 Available Organics organic material (0.3 ha) - total available = 2,895 m 3 December 2011 Section 5-8

5.7.2 BORROW PITS There are four borrow pits (31.0 ha) proposed for project development. Approximately 30.6 ha are considered upland and 0.4 ha deep organic soil (Borrow Pit 2) will be salvaged for replacement at reclamation. In addition to the topsoil and organic material salvage, Pengrowth may also stockpile materials excavated during borrow pit development that are not suitable for construction purposes. This subsoil material would be stored separately from the salvaged topsoil and organic material and used to recontour the borrow disturbance at reclamation. Borrow Pit 1 has already been disturbed and the salvaged topsoil material is located on the edge of the current disturbance. This material will be utilized at reclamation to reclaim the borrow disturbance. Figure 5.7-2 displays existing and proposed topsoil stockpiles for the non PDA Project components. The existing topsoil piles displayed in Figure 5.7-2 have been measured and GPS coordinates recorded in order to determine approximate volumes of available topsoil material. The following is a summary of the soil material available within the borrow pits and the amount planned for salvage: Borrow Pit 1 (1.3 ha) Topsoil volumes based on estimated volume of existing topsoil pile located within the borrow disturbance. Planned Salvage: upland topsoil (1.3 ha) = 6,288 m 3 organic material (0.0 ha) = none available Borrow Pit 2 (5.9 ha) Planned Salvage: upland topsoil (5.4ha) = 18,975 m 3 organic material (0.4 ha) = 6,200 m 3 Borrow Pit 3 (17.0 ha) Planned Salvage: upland topsoil (17.0 ha) = 49,399 m 3 organic material (0.0 ha) = none available Borrow Pit 4 (6.8 ha) Detailed in PDA/C&R Plan Planned Salvage: upland topsoil (6.8 ha) = 18,174 m 3 December 2011 Section 5-9

organic material (0.0 ha) = none available 5.7.3 PIPELINE RE-ROUTING & SOURCE WATER LINE All of the 1.1 ha of the re-routing corridors (two separate corridors) and all 0.6 ha of the source waterline route is considered upland. For both underground facilities the topsoil layer will be salvaged, by pushing the soil material to the edge of the right of way, out of the way of construction activities. Subsoil material excavated from the trench will be stockpiled separately from the salvaged upland topsoil material. Excavated subsoil material will be replaced into the trench upon completion of line installation. The following is a summary of the soil material available and the amount planned for salvage: Pipeline Re-routing Planned Salvage: upland topsoil (1.1 ha) = 2,627 m 3 organic material (0.0 ha) = none available Source Water Line Planned Salvage: upland topsoil (0.6 ha) = 1,736 m 3 organic material (0.0 ha) = none available 5.7.4 SOIL STORAGE AREAS Nine soil storage areas are designated for the Project footprint totalling 20.9 ha (18.9 ha upland and 2.0 ha deep organic (Figure 5.7-1)). Details on soil storage areas 1 to 4 are provided in the PDA/C&R Plan and soil storage locations 5 to 9 are non-pda components (Figure 5.2-1). Topsoil and organic material salvaged from the adjacent well pads, borrow pits, CPF, and camp sites will be stockpiled within the designated storage areas. Pengrowth will be stockpiling soil materials on like material. Topsoil material beneath soil stockpiles will not be salvaged however topsoil material beneath subsoil stockpiles will be salvaged. Soil storage area 2 will be utilized for the storage of subsoil material from the CPF. Topsoil material will be salvaged from the portion of this location where the subsoil material is expected to be stockpiled. Below is a summary of material available within all of the soil storage areas. However, only Soil Storage 2 provides proposed planned salvage volumes (Soil Storage 2 is expected to accommodate subsoil material salvaged from the CPF). December 2011 Section 5-10

Soil Storage 1 (1.1 ha) Material Available: upland topsoil (1.1 ha) = 2,459 m 3 organic material (0.0 ha) = none available Soil Storage 2 (6.5 ha) Planned Salvage: upland topsoil (2.0 ha) = 4,640 m 3 organic material (0.0 ha) = none available Soil Storage 3 (3.5 ha) Material Available: upland topsoil (3.5 ha) = 10,002 m 3 organic material (0.0 ha) = none available Soil Storage 4 (1.7 ha) Material Available: upland topsoil (1.7 ha) = 4,938 m 3 organic material (0.0 ha) = none available Soil Storage 5 (2.8 ha) Material Available: upland topsoil (2.8 ha) = 8,078 m 3 organic material (0.0 ha) = none available Soil Storage 6 (0.9 ha) Material Available: upland topsoil (0.9 ha) = 2,139 m 3 organic material (0.0 ha) = none available December 2011 Section 5-11

Soil Storage 7 (1.0 ha) Material Available: upland topsoil (1.0 ha) = 2,001 m 3 organic material (0.0 ha) = none available Soil Storage 8 (1.4 ha) Material Available: upland topsoil(1.0 ha) = 2,478 m 3 organic material (0.4 ha) = 5,700m 3 Soil Storage 9 (1.9 ha) Soil Storage 9 is associated with Well Pad 4; no material will be salvaged for placement on soil storage 9 during construction activities. Well Pad 4 is situated on deep organics, which will be padded over and no salvage of deep organics are expected (Figure 5.7-1). Material Available: upland topsoil (0.3 ha) = 616 m 3 organic material (1.6 ha) = 22,100 m 3 5.7.5 CONSTRUCTION, OPERATIONS AND SUPERVISOR S CAMPS All lands within the Construction Camp (10.1 ha) and Operations Camp (3.2 ha) are considered to be uplands and will have the topsoil material salvaged and stockpiled in the designated soil storage areas for replacement at reclamation. The Supervisor s Camp and Access is located in an existing disturbance (mapped as ZDL) and the salvaged soil material is stockpiled adjacent to the existing disturbance (Figure 5.7-2). All stockpiled material will be used in reclamation. Construction Camp (10.1 ha) Detailed in PDA/C&R Plan Planned Salvage: upland topsoil(1.1 ha) = 25,205 m 3 organic material (0.0 ha) = none available Operations Camp (3.2 ha) Detailed in PDA/C&R Plan Planned Salvage: upland topsoil(3.2 ha) = 6,375 m 3 December 2011 Section 5-12

organic material (0.0 ha) = none available Supervisor s Camp and Access (1.1 ha) Available Soil Materials: upland topsoil (1.1 ha) = 2,797 m 3 (estimated volume currently in stockpile) organic material (0.0 ha) = none available 5.7.6 WELL PADS There are four well pads planned for the Project (well pads 1 to 4) totalling 16.8 ha. Approximately 12.5 ha of the well pads are considered upland and the remaining 4.3 ha are located in deep organics (Figure 5.7-1). All upland areas will have the topsoil material salvaged and stockpiled in associated soil storage areas for replacement. Well Pad 4 is located entirely in deep organics. Deep organics will not be salvaged; all deep organic soils will be padded over with geogrid and clay fill material. The following is a summary of the soil material available within the four well pads and the amount planned for salvage: Well Pad 1 (4.0 ha) Planned Salvage: upland topsoil (4.0 ha) = 11,591 m 3 organic material (0.0 ha) = none available Well Pad 2 (3.8 ha) Planned Salvage: upland topsoil (3.8 ha) = 9,548 m 3 organic material (0.0 ha) = none available Well Pad 3 (4.7 ha) Planned Salvage: upland topsoil (4.7 ha) = 11,090 m 3 organic material(0.0 ha) = none available Well Pad 4 (4.3 ha) Planned Salvage: upland topsoil (0.0 ha) = none available December 2011 Section 5-13

5.7.7 CPF organic material (4.3 ha) = 0 m 3 Available Organics organic (4.3 ha) - total available = 60,400 m 3 The CPF consists of 24.1 ha of upland soils. All upland topsoil material within the CPF will be salvaged and stockpiled in the designated soil storage areas for replacement at reclamation. Subsoil material, to a maximum thickness of 30 cm, will also be salvaged from the CPF and stockpiled separately from topsoil material within the designated CPF soil storage area(s). Detailed information on the soil salvage process for the CPF is located in the PDA/C&R Plan. The following is a summary of the soil materials available within the CPF and the amount planned for salvage: CPF (24.1 ha) Planned Salvage: upland topsoil (24.1 ha) = 62,945 m 3 upland subsoil material (24.1 ha) = 72,166 m 3 5.7.8 REMOTE SUMPS There are two remote sumps for the Project totalling 9.6 ha, which are all upland soils. Prior to development, all topsoil material will be salvaged and stockpiled in designated soil storage locations within each facility. Remote Sump 1 (4.7 ha) Planned Salvage: upland topsoil (24.1 ha) = 12,712 m 3 organic material (0.0 ha) = none available Remote Sump 2 (4.9 ha) Planned Salvage: upland topsoil (4.9 ha) = 13,621 m 3 organic material (0.0 ha) = none available December 2011 Section 5-14

5.8 SOIL STORAGE Topsoil and organic soils that are salvaged, as described in Section 5.7.1 to 5.7.8, will be placed in designated stockpiles. Figure 5.7-2 displays the proposed location of stockpiles for all non PDA components. Detailed soil storage for the PDA components is provided in the PDA/C&R Plan. Stockpiles will be constructed as follows: soil will be stockpiled on like material (i.e., topsoil stockpiled on topsoil); topsoil and subsoil material will be stockpiled separately from each other and from other materials; long-term stockpiles will have a set-back of 5 m from standing timber; stockpile foundations will be stable; stockpiles will be stabilized to control water and wind erosion; stockpiles will be accessible and retrievable; stockpiles will be revegetated and controlled for weeds; stockpiles will include signage that indicates, at a minimum, the type of reclamation material in the stockpile; and soil will be stored out of the way of surface water flow. 5.9 FINAL SITE GRADING AND RE-CONTOURING The majority of the Project is located on hummocky and high-relief, undulating terrain (slopes range from 5-15%). Pengrowth will recontour disturbed uplands to approximate the natural landforms in the areas and will re-establish surface drainage on reclaimed areas such that surface drainage is integrated with the adjacent lands and natural drainage patterns. Final recontouring will involve the removal of fill material where applicable, ripping, decompaction and contouring to blend with surrounding areas. Once the recontouring is complete, the areas will be ready for soil replacement and vegetation. Recontouring of access corridors will focus on restoration of drainage patterns that existed prior to disturbance. Watercourse crossings will be removed as part of the final reclamation. In places where fill material was used to pad over organic soils, the fill will be left in place and re-contoured to create upland and transitional reclaimed landscapes suitable for establishment of agronomic vegetation communities suitable for grazing. Surplus topsoil material from borrow pits 2 and 3 will be utilized to reclaim organic landscapes padded over at construction. Details on expected volumes to be utilized for reclamation of padded areas are detailed in Section 5.11. December 2011 Section 5-15

The completed borrow pits will be contoured to have side slopes graded to be no steeper than 4:1. Subsoil material stockpiled during borrow pit development will be used for recontouring of the depleted borrows. Pengrowth expects that 30-50% of the borrow disturbances will be reclaimed as a dugout and/or wetland depending on the location of the borrow pit in the landscape and volume of material extracted for construction. With these side slopes, it is expected they could also be used for livestock watering. Conceptual reclaimed cross sections of Borrow pits1 to 3 are provided in Figures 5.9-1a to c. Details on recontouring and reclamation of Borrow pit 4 is provided in the PDA/C&R Plan. 5.10 EROSION AND SEDIMENT CONTROL Throughout the life of the Project operational areas, stockpiled materials, water pump off areas, and watercourse crossings will be monitored for signs of erosion. If erosion concerns arise an erosion control plan will be implemented based on specific needs required. Possible erosion control methods include, but are not limited to silt fencing; brush or rock berm; continuous (earth-filled geogrid) berm; earth dyke barrier; hydroseeding or hydromulching; addition of tackifiers; and slope texturing. Erosion control implemented will be site-specific and continuous monitoring and maintenance will be performed as required. 5.11 SOIL REPLACEMENT PLAN Within the Project footprint, approximately 410,635 m 3 of salvaged topsoil will be replaced over the life of the Project. The reclamation material balance for the Project is provided in Table 5.11-1 and a summary of expected soil replacement activities is summarized below. A key component of this reclamation and soil replacement plan will see the fill material that was placed over the organic soils, left in place and excess soil material from adjacent borrow pits will be placed over top (after decompaction and conditioning). This has been discussed with the local SRD reclamation inspector and the range management specialist and creating improved rangeland habitat for livestock is a key consideration. December 2011 Section 5-16

5.11.1 ACCESS / PIPELINE CORRIDORS For access roads, upland soil material will be spread over the re-contoured and de-compacted former road beds for all former access roads. In organic landscapes where the clay fill material will be left in place and re-contoured excess upland topsoil material from adjacent borrow pit developments will be utilized. In total, an estimated 54,685 m 3 of upland topsoil will be replaced over the former main access and infield roads and pipe corridors; of this volume approximately 23,500 m 3 will be used on the 5.1 ha of reclaimed road that was initially an organic landscape. This material will be surplus soil material from the developed borrow pits. The average replacement depth of topsoil in reclaimed corridors is estimated at 25 cm. 5.11.2 BORROW PITS Once a borrow pit has been completed and re-contoured, soil replacement will commence. The estimated soil volumes for replacement and the replacement depths are based on a reduction of replacement area by 30-50% (due to formation of a dugout and/or wetland) and also consider the relocation of surplus topsoil material replacement for reclamation of former organic landscapes padded at construction (soil is expected to be utilized from borrow pits 3 and 4). Expected soil replacement for the borrow pits is based on the conceptual disturbance areas as follows: Borrow pit 1 (1.3 ha) 6,288 m 3 of salvaged topsoil material replaced over approximately 0.7 ha of re-contoured lands; average replacement depth of 90 cm; Borrow pit 2 (5.9ha) 18,975 m 3 of salvaged topsoil and deep organic material replaced over approximately 3.0 ha of re-contoured lands; average replacement depth of 63 cm; Borrow pit 3 (17.0 ha) 27,247 m 3 of salvaged topsoil material replaced over approximately 8.5 ha of re-contoured lands; average replacement depth of 32 cm. Approximately 22,853 m 3 of surplus material from Borrow pit 3will be used to reclaim well pad four (4.3 ha) and a portion of the access that was constructed in organic landscapes (4.8 ha); and Borrow pit 4 (6.8 ha) 17,527 m 3 of salvaged topsoil material replaced over approximately 4.5 ha of re-contoured lands; average replacement depth of 39 cm. Approximately 647 m 3 of surplus material from Borrow pit 4will be used to reclaim a portion of the access that was constructed in organic landscapes (0.3 ha). Replacement depths provided are average values based on the estimated disturbance area requiring topsoil replacement. The actual replacement values will be variable as topsoil material will be replaced on the landscape to allow for the development of a variety of moisture and nutrient regimes in the reclaimed landscape. December 2011 Section 5-17

5.11.3 PIPELINE RE-ROUTING & SOURCE WATER LINE The salvaged topsoil layer will be replaced evenly over the backfilled and compacted trench line. The replaced topsoil layer may be slightly elevated above natural grade to allow for minor subsidence as a result of material settling. In total, an estimated 4,363 m 3 of upland topsoil will be replaced over these components with an average replacement depth of 27 cm. 5.11.4 SOIL STORAGE AREAS Topsoil salvage within the soil storage areas is only required for Soil storage area 2. This is the location where the subsoil material salvaged from the CPF is likely to be stored. Topsoil replacement information is provided for Soil storage area 2: Soil Storage 2 (6.5 ha) approximately 4,640 m 3 of upland soil will be replaced over the re-contoured area are where subsoil material salvaged from the CPF had been stored; with an average replacement depth of 23 cm. No organic soils occur within this area. 5.11.5 CONSTRUCTION, OPERATIONS AND SUPERVISOR CAMPS For the Supervisor s Camp and Access, the salvaged soil material is located in stockpiles adjacent to the project component and will be replaced evenly over the disturbed area. An estimated 2,797 m 3 of material in stockpile will be replaced. The average replacement depth of topsoil is estimated at 26 cm. The construction camp (10.1 ha) will receive approximately 25,205 m 3 of stockpiled topsoil to a target replacement depth of 25 cm and the operations camp (3.2 ha) will receive approximately 6,375 m 3 of stockpiled topsoil to a target replacement depth of 20 cm. 5.11.6 WELL PADS The following is a summary of the soil placement plan for the well pads: Well pad 1 (4.0 ha) approximately 11,600 m 3 of upland soil will be replaced over the re-contoured area with an average replacement depth of 29 cm. Well pad 2 (3.8 ha) approximately 9,500 m 3 of upland soil will be replaced over the recontoured area with an average replacement depth of 25 cm. Well pad 3 (4.7 ha) - approximately 11,100 m 3 of upland soil will be replaced over the recontoured area with an average replacement depth of 24 cm. Well pad 4 (4.3 ha) approximately 10,750 m 3 of upland soil from borrow pit 3 will be replaced over the re-contoured well pad area with an average replacement depth of December 2011 Section 5-18

25 cm. Well pad 4 was padded over for construction and it will be reclaimed to an upland / transitional landscape. 5.11.7 CPF Salvaged subsoil will be replaced following recontouring within the CPF. Approximately 72,166 m 3 of upper subsoil will be spread evenly across the CPF to a target replacement depth of 30 cm. After replacement of upper subsoil, approximately 62,945 m 3 of topsoil will be distributed across the CPF to a target replacement depth of 26 cm. 5.11.8 REMOTE SUMPS Prior to replacement of the topsoil material Pengrowth will ensure all sump cell disturbances have been mixed as per regulatory requirements and re-contoured to reduce the potential for subsidence. Approximately 12,712 m 3 of topsoil will be distributed over 4.7 ha of reclaimed former Remote Sump 1 to a target replacement depth of 27 cm. Approximately 13,621 m 3 of topsoil will be distributed over 4.9 ha of reclaimed Remote Sump 2 to a target replacement depth of 28 cm. Pengrowth will replace the salvaged soil material uniformly over the reclaimed sump areas. December 2011 Section 5-19

5.12 POST RECLAMATION LAND CAPABILITY As determined through conversations with the SRD reclamation inspector and the range management specialist, Pengrowth will reclaim disturbed lands to achieve land capability suitable for the desired end land use of improved pasture. The post reclamation land capabilities will be similar to the ratings determined for the pre-disturbance soil map units with the exception of organic landscapes or transitional / depressional landscapes. Pengrowth intends to reclaim organic and transitional landscapes into post disturbance landscapes similar to adjacent undisturbed uplands. Baseline LCCS ratings are provided in Figure 5.12-1 and reclaimed ratings are presented in Figure 5.12-2. Comparison of the baseline and reclaimed LCCS ratings for the Project footprint are provided in Table 5.12-1. Changes expected to the distribution of reclaimed ratings as a result of the Project include: total of 5.1 ha of access roads and well pad 4 (4.3 ha) that will be reclaimed as upland landscapes; portions of the project footprint that were mapped as disturbed lands (ZDL) and will be reclaimed to provide a suitable reclaimed landscapes to meet the end land use; and borrow pit development will result in the creation of open water / wetlands that will remove some uplands in the reclaimed landscape.

5.13 REVEGETATION PLAN As a result of discussions with ASRD, Pengrowth plans to reclaim the Project to an improved pasture end land use. The reclaimed areas will be revegetated with a weed-free seed mixture suitable for tame pasture, which will include agronomic species. The lessee in this area has advised that their desired seed mix would consist of a grazing mixture containing approximately 33% alfalfa, 33% brome and 33% fescue with a small amount of cicer milk vetch. This type of seed mix will be utilized for revegetation of all disturbed sites. All seed used during reclamation will meet Canada No 1 certified seed standards. Seeding rates will vary depending on location and degree of disturbance, and seeding rates may be increased where required. Where possible, conventional reclamation equipment (tractors and a seed drill) will be utilized to complete seeding activities. In situations where this seeding method is impractical due to slope conditions and/or wet or unstable soil, broadcast seeding with a quad and harrows may be utilized. Fertilization will be completed when and where required. If any nutrient deficiencies are discovered or of concern, soil testing will be completed and a fertilization plan will be implemented to ensure reclaimed areas have nutrient regimes equivalent to undisturbed areas. The primary objective of the revegetation plan is to provide a site condition suitable for self-sustaining improved pasture for livestock production and watershed protection, with possibilities for recreation and other end uses. 5.13.1 RECLAIMED ECOSITES Baseline ecosite phase polygons were used to calculate post reclamation ecosite areas. The shape and orientation of the polygons will be altered as a result of development, and the reclaimed ecosite distribution within the Project footprint will be dissimilar to pre-existing patterns to accommodate the desired end land use. Figure 5.13-1 displays the baseline ecosites located within the Project footprint and Figure 5.13-2 displays the estimated reclaimed ecosites for the Project footprint based on the desired end land use and proposed reclamation strategies to be utilized by Pengrowth. Table 5.13-1 displays the comparison of the baseline and estimated reclaimed ecosites within the Project footprint. December 2011 Section 5-22

Pengrowth will also comply with ASRD s Weed Management in Forestry Operations - Directive 2001-06 (ASRD 2001). Control of invasive weed species will be completed through the establishment of vegetation on soil stockpiles as well as during interim reclamation to mitigate weed populations in disturbance areas. Inspections for the presence of weed species will be performed during the Project life. Pengrowth will work in consultation with ASRD to decide which method(s) is best in controlling weeds on site. Non-chemical control of weeds is the preferred method and includes mowing, cultivation, or hand picking. Herbicides applied will be appropriate for site conditions, and only non residual herbicides will be considered. 5.14 RECLAMATION MONITORING PROGRAM Reclamation monitoring will be included in an Annual Report to be used to document the success of reclamation efforts, and, over time, allow for adaptive management of the reclamation December 2011 Section 5-23

and re-vegetation programs throughout the life of the Project. This report will be submitted to AEW as an approval requirement. December 2011 Section 5-24
