ANNUAL RECLAMATION REPORT FOR 2007/2008 <br />1.0 BACKGROUND <br />On March 15, 2006, the State of Colorado Division of minerals and Geology approved the <br />EnCana Oil & Gas (USA) Inc. (EnCana) 112c mining permit application for the West Fork Pit <br />(Permit No. M-2205-069). The West Fork pit is located in portions of Lot 4 and the S1/2,W1/2 <br />and NW1/4 of Section 3, Township 5 South, Range 96 West, 6`h P.M. and in the road corridor in <br />Lot 4 with an Avenue width of 130 feet in Section 34, Township 4 South, Range 96 West, 6th <br />P.M. <br />2.0 CONSTRUCTION SUMMARY <br />The following summary is the 2007/2008 annual summary report of the West Fork Pit. In 2007, <br />EnCana did not remove any material from the West Fork Pit. In 2008, EnCana removed <br />sandstone shale from the pit for construction of access roads and related oil and gas facilities. <br />During initial construction of the West Fork Pit in 2006, EnCana's contractor disturbed <br />approximately 4.0 acres of the previously approved 18.4 acres. The topsoil was bladed to a <br />depth of three to six inches across the 4-acre area and segregated along the east, south and <br />western sides of the pit to create a stormwater containment pit. Excess material not removed <br />from the pit during the 2008 activities was then leveled out across the pit. The pit floor is <br />sloping to the south at approximately 3 to 4%. The walls of the pit are approximately 2v:lh. <br />The quarry pit has been excavated approximately 10 feet deep. <br />3.0 EROSION CONTROL <br />EnCana's contractor constructed a soil berm around the outside perimeter of pit during the <br />topsoil grading activities when the pit was first constructed. The topsoil stock pile was located <br />adjacent to a perimeter soil berm constructed for secondary containment for potential storm <br />water runoff. No additional temporary or permanent erosion measures are currently necessary at <br />the site. <br />4.0 RECLAMATION <br />The topsoil pile was reseeded with the EnCana North Parachute Ranch Upper Elevation seed <br />mix, which includes the following seed mixture. <br />Recommended Seed Mix for Upper Zone Disturbance <br />Species Variety cultivar Seeding Rate PLS*/Acre <br />Grasses <br />Slender Wheatgrass San Luis 3.0 lbs. <br />Mountain Brome Garnet 2.0 lbs. <br />Nodding Brome 2.0 lbs. <br />Idaho Fescue or Letterman's Needlegrass 1.0 lbs. <br />2
