<br />MR24-325 2.05-84.15 03/27/24 <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 450’ <br />X 450’ for an area of ~4.65 acres. The access road will be a total of 6,300 feet and 30 feet wide for a total area of <br />disturbance equal to 4.34 acres. 3,500 feet of the access road is an existing ranch road that will be improved for truck <br />traffic. TC will recover and salvage 12 inches of topsoil for an approximately volume of 7,500 cubic yards. Soil <br />salvage volumes are indicated on Table 49A. <br /> <br /> <br />WC Mains Utility Borehole (MR24-325) – Access Road and pad construction for the WC Mains Utility Borehole <br />will involve removing the vegetation and stripping and stockpiling the topsoil. The access road and pad are located <br />along the top of a ridge line, some earthwork will be required for the pad site. The pad will be approximately 200’ x <br />200’ plus the topsoil and pad sloping will create a disturbance of roughly 2 acres. The access road is an existing <br />two-track that will require minor improvements. TC will recover and salvage 12” of topsoil amounting to a volume <br />of approximately 1,670 cubic yards of topsoil from the disturbance area. Soil salvage volumes are indicated on Table <br />49A. <br /> <br /> <br />6 East Utility Borehole (MR24-325) – Access Road and pad construction for the 6 East Utility Borehole will involve <br />removing the vegetation and stripping and stockpiling the topsoil. The new sections of access road and pad are <br />located on minimal sloping ground and will require little earthwork. The pad site and new access road will result in <br />a new disturbance area of approximately 1.7 acres and will require the recovery and stockpile of approximately 2,700 <br />cubic yards of topsoil. Soil salvage volumes are indicated on Table 49A.
