0.35 acres, and a total pipeline disturbance area of approximately 7.2 acres, approximately 300 cubic yards of soil material will be salvaged from the pad area, and 5,750 cubic yards from the pipeline corridor. Soil from the pipeline corridor will be removed and windrowed along one side of the pipeline corridor, and soil from the pad area will be placed in a stockpile within the borehole pad for future reclamation use. The soil salvage volumes are indicated on Table 49A. Natural vegetative materials (mulch) incorporated into the topsoil, and seeding with the topsoil stockpile stabilization seed mixture, identified on page 2.05 -121, will stabilize and protect the stockpiled soil materials. 15RT Ventilation Shaft (TR11 -77) - An existing two -track road extends from the Fish Creek Water Treatment Facility road to the proposed shaft site, however, it does not appear that any soil material was salvaged from the road corridor. Therefore, for both the light -use road and shaft pad, construction will involve removal of any large vegetation and stripping and stockpiling of other vegetation, soil, and organic materials. TCC will recover and salvage a maximum of 18 inches of soil from the road and pad areas. With a pad area of approximately 1.6 acres, and a road corridor of approximately 0.7 acres, a maximum volume of approximately 5,600 cubic yards of soil material will be salvaged and placed in stockpile for future use in reclaiming the site. A temporary soil stockpile will be established on the east end of the pad area, natural drainage will be diverted around the stockpile by a short diversion ditch, and the natural vegetative materials incorporated into the soil, and seeding with the topsoil stockpile stabilization seed mixture, will stabilize and protect the stockpiled soil materials.. Soil salvage volumes are indicated on Table 49A. 16LT Utility Borehole (TR11 -78) — The associated light -use road follows an existing two -track ranch road for part of its length, however, it does not appear that any soil material was salvaged from the road corridor. Therefore, for both the light -use road and borehole pad, construction will involve removal of any large vegetation and stripping and stockpiling of other vegetation, soil, and organic materials. The road is located near the top of a ridgeline where soil development is limited, so TC will recover and salvage a maximum of 12 inches of soil from the road and pad areas. With a pad area of approximately 2.2 acres, and a road corridor of approximately 6.1 acres, a maximum volume of approximately 10,900 cubic yards of soil material will be salvaged and placed in stockpile for future use in reclaiming the site. A temporary soil stockpile(s) will be established on the east end of the pad area adjacent to the road, where natural drainage will route around the stockpile(s) due to the existing natural drainage configuration, and the natural vegetative materials incorporated into the soil, and seeding with the topsoil stockpile stabilization seed mixture, will stabilize and protect the stockpiled soil materials.. Soil salvage volumes are indicated on Table 49A. 5NIN Cement Borehole (MR14 -283) — Construction of the light -use road and pad for the 5MN Cement Borehole will involve removal of any large vegetation and stripping and stockpiling of other vegetation, soil, and organic materials. The road and pad are located along the crest of a minor ridgeline where soil development is limited, so TC will recover and salvage a maximum of 12 inches of soil from the road and pad areas. With a pad area of approximately 0.9 acres, and a road corridor of approximately 3.1 acres, a maximum volume of approximately 6,540 cubic yards of soil material will be salvaged and placed in stockpile for future use in reclaiming the site. A temporary soil stockpile(s) will be established on the northeast corner of the pad area adjacent to the road. The natural vegetative materials incorporated into the soil, and seeding with the topsoil stockpile stabilization seed mixture, will stabilize and protect the stockpiled soil materials. Soil salvage volumes are indicated on Table 49A. MR14 -283 2.05 -84.11 10/09/14
