5.0 CONSERVATION AND RECLAMATION PLAN

5.1       Introduction
The Conservation and Reclamation (C&R) Plan for the Pilot Project serves to provide the
conceptual information about the ultimate closure and abandonment plans for the facilities once
the Project has ceased operations. It provides information about the reclamation activities that
LEL will carry out to ensure that environmental impacts are kept to a minimum and end land use
objectives and goals are attained.

The project components for the Pilot Project are listed in Table 5.1-1.

                             Requirements

To supplement this C&R Plan, once the Pilot Project is operational, LEL will prepare an Annual
C&R Report that will outline development work that was completed in the previous year and
activities that are planned for the following year. In compliance with the EPEA, an
abandonment and reclamation plan will be submitted to AENV six months before
decommissioning of the surface facilities.


5.2       Reclamation Goals and Objectives
Developed lands will be reclaimed to achieve equivalent capability to pre-disturbance conditions
resulting in reclaimed landscapes that are compatible with the surrounding landscape, including
forested areas and wetlands.

LEL will use the following objectives as the basis for operational and reclamation program
design:

      •   Facility development, well pads, roadways, pipelines, and other landscape alterations will
          be constructed to be geotechnically stable.

                                                                              LARICINA ENERGY LTD.
                                                                               Saleski SAGD Pilot Project


      •   Reclamation will be designed to create a landscape that is self-sustaining and capable of
          supporting those soils and vegetation processes typical of the adjacent undeveloped area
          with no subsequent management input required.
      •   Following soil replacement or de-compaction, vegetation communities will establish and
          will be capable of ecological succession processes similar to those found within the
          region.
      •   On those localized sites that are sensitive to erosion (i.e. steeper erodable slopes, 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
          ensure an acceptable level of input into the streams that flow into natural watershed.
      •   Reclaimed lands will meet the criteria for certification.

The areas disturbed by construction activities will be progressively reclaimed to minimize post-
construction impacts such as soil erosion. Final reclamation will be undertaken when the Pilot
Project is abandoned and all of the facilities are removed.


5.3       Soil Salvage
All topsoil will be salvaged and replaced to ensure that the reclaimed areas will support
revegetation activities, allow ecological succession and achieve equivalent land capability to the
pre-development conditions. Topsoil is defined as “the surface forest floor and all “A Horizon”
soil (LFH, Ah, Ahe and Ae)” (ANV, 2007). Topsoil material will be salvaged, within the project
disturbance limits, from mineral soils which are defined as having less than 40 cm of surface
peat. Approximate topsoil volumes available for salvage are shown in Table 5.3-1. With respect
to the Plant Site, Well Pad and Associated Infrastructure there is sufficient topsoil available to
replace 20 cm of soil material, consisting of approximately 10 cm of surface litter material and
10 cm of A horizon material. For the Access Road and Borrow Pits, there is sufficient topsoil
available to replace 22 cm of soil material, consisting of approximately 10 cm of surface litter
material and 12 cm of A horizon material. Details with respect to assessing baseline soil
conditions, soil mapping and determining suitable soil salvage depths for the Project are
provided in Section 4.4 of this report.

Topsoil materials will be removed in a single lift with the overlying litter layer. Total soil
salvage depths will typically range between 15 to 30 cm depending on soil type and landscape
position. During site construction, soils with peat material greater than 40 cm will be left intact,
with geo-textile placed on top, and fill material placed on the geotextile. Fill material will be

obtained from borrow pits and will have all suitable litter and A Horizon material salvaged for
subsequent soil replacement at time of reclamation.

5.4     Final Site Grading and Recontouring
Once it has been deemed that a particular component of the site infrastructure is no longer
required (e.g. borrow pits) final site grading and re-contouring activities will take place.

Final contouring of the site will be carried out so that it blends into the natural landscape and site
drainage is established and integrated into the drainage patterns of the surrounding area. Where
possible, final site preparation will be re-contoured to near natural drainage patterns and
topography.

During final reclamation, side slopes of the borrow areas will be graded to a 3:1 slope. Past
experience indicates that these areas will develop naturally into boreal forest wetlands. Post
reclamation monitoring will be undertaken for a period of time to satisfy regulators and
stakeholders that reclamation efforts are successful and that the reclaimed areas are maturing and
self sustaining.

5.5       Soil Replacement Plan
For surface pipelines, following construction and installation, suitable soil material will be
immediately replaced and seeded on the right of ways to minimize impacts related to erosion.

With respect to other project infrastructure, suitable soil material will be placed once final re-
contouring and de-compaction of the fill material is complete. The goal of soil replacement is to
establish a soil profile that permits the establishment of an initial vegetation cover, subsequent
natural recovery of the plant community and initiation of natural soil processes such that land
capability equivalent to that which existed prior to disturbance is achieved. The reclaimed soil
profile will provide:

      •   adequate moisture supply;
      •   adequate nutrient supply; and
      •   capability to support a self-sustaining vegetative cover.

Soil handling practices are designed to follow the guidelines provided in Land Capability
Classification for Forest Ecosystems in the Oil Sands Region, Working Manual (CEMA 2006).
Equivalent forest capability is the primary consideration for soil reclamation. The reclamation
material balance is provided in Table 5.3-1. Within the disturbance limits of the Pilot Project
area, approximately 166.4 ha are covered by mineral soils, 87.9 ha are covered by organic soils
and the remaining 2.2 ha are sited on previously disturbed lands. With respect to reclamation of
site disturbance on organic/peat soils, all geo-textile and fill material will be removed and the
peat surface will be de-compacted to allow for revegetation and water movement. Since the
organic material will have been left in place, additional replacement of suitable soil material is
not required.

Approximately 362,398 m3 of topsoil will be salvaged and replaced. LEL is committed to
replacing sufficient soil materials to ensure that equivalent capability is returned on the
reclaimed landscape.


5.6       Revegetation
LEL will follow the recommendations provided by the Oil Sands Vegetation Reclamation
Committee. The committee’s report Guidelines for Reclamation of Terrestrial Vegetation in the
Alberta Oil Sands Region (OSVRC, 1998) forms the basis for future revegetation activities on
reclaimed sites.

In consultation with ASRD, LEL will select an approved seed mix that will be used on the
reclaimed landscape. Seed will generally be applied by broadcast methods. Revegetation of
disturbances will be phased to coincide with construction activities to limit the area of exposed
soil at any one time. Weed control will be undertaken as required.


5.7     Reclamation Monitoring
LEL will monitor results of the reclamation program in accordance with the requirements
outlined in the EPEA operating approval.
