MR21-319 2.05-84.15 07/27/21 <br />salvaged and placed in stockpile for future use in reclaiming the site. A temporary soil stockpile(s) will be established <br />on the northwest side of the pad area. The natural vegetative materials incorporated into the soil, and seeding with <br />the topsoil stockpile stabilization seed mixture, will stabilize and protect the stockpiled soil materials. Soil salvage <br />volumes are indicated on Table 49A. <br />9-East Utility Borehole Installation (MR16-296) - Light-use road and pad construction for the 9-East Utility <br />Borehole Installation will involve removal of any large vegetation and stripping and stockpiling of other vegetation, <br />soil, and organic materials. The road and pad are located on a low-gradient sidehill, with a pad area of approximately <br />2.1 acres, and a road corridor of approximately 1.6 acre. TC will recover and salvage up to 2 feet of soil from the <br />road and pad areas, resulting in recovery and stockpiling of a maximum volume of approximately 11,880 cubic yards <br />of soil material for future use in reclaiming the site. Note that, based on available soil mapping information and <br />descriptions, soil depths in the project area vary, but may be up to 38-inches in thickness. TC proposes to recover up <br />to 24-inches of soil, both in order to minimize site disturbance and because replacement of 24-inches of soil material <br />is more than adequate to support effective revegetation efforts in this area. Temporary soil stockpiles will be <br />established at reasonable intervals along the road and adjacent to the pad area. The natural vegetative materials <br />incorporated into the soil, and seeding with the topsoil stockpile stabilization seed mixture, will stabilize and protect <br />the stockpiled soil materials. Soil salvage volumes are indicated on Table 49A. <br /> <br /> <br />7 East Cross Entries Borehole (TR21-97) - Access road and pad constructions for the 7 East Cross entries borehole <br />will involve removing the vegetation and stripping and stockpiling the topsoil. The access road and the pad are located <br />on minimal sloping ground therefore very little earthwork will be required. The pad site will be approximately 300’ <br />X 300’ for an area of ~2 acres. The access road will only be 140 feet and 30 feet wide for a total area of disturbance <br />equal to 2.2 acres. TC will recover and salvage 12 inches of topsoil for an approximately volume of 3,485 cubic <br />yards. Soil salvage volumes are indicated on Table 49A. <br /> <br /> <br />18LT Dewatering Borehole (MR21-319) - Access road and pad constructions for the 18LT Dewatering borehole <br />will involve removing the vegetation and stripping and stockpiling the topsoil. The access road and the pad are located <br />on minimal sloping ground therefore minimal earthwork will be required. The pad site will be approximately 175’ <br />X 200’ for an area of ~1 acres. The access road will be 2,100 feet and 30 feet wide for disturbance equal to ~2 acres. <br />TC will recover and salvage 12 inches of topsoil for an approximately volume of 3,600 cubic yards. Soil salvage <br />volumes are indicated on Table 49A.
