marked with identifying signs to prevent surface disturbance within buffer zone areas. The topsoil from the road <br />corridor was initially windrowed adjacent to the road and topsoil from the pad area was placed in a stockpile <br />adjacent to the shaft pad and within the road corridor, for future reclamation use. As a result of concerns related to <br />protection of windrowed topsoil from erosion and contamination, a decision was made to recover topsoil from the <br />windrows and place it in stockpile. The topsoil salvage volumes are indicated on Table 49A. Seeding with the <br />topsoil stockpile stabilization seed mixture identified on page 2.05-121 will stabilize the windrowed and stockpiled <br />topsoil. <br />6-North Mains Ventilation Shaft (TROS-48) <br />Along the 2,930-foot access road, construction will involve removal of any large vegetation and stripping and <br />stockpiling of other vegetation, topsoil, and organic materials. Similarly, the shaft pad is located in an upland area. <br />Given an average topsoil depth of approximately 6 inches in the upland area and a total road disturbance area of <br />approximately 2.4 acres, approximately 1,940 cubic yards of topsoil will be salvaged from the road corridor, and <br />8,954 cubic yards from the 11.1 acre pad area. Prior to initiating topsoil removal activities, wetland buffer zones <br />will be marked with identifying signs to prevent surface disturbance within the buffer zone areas. The topsoil from <br />the road corridor will be recovered and placed in a stockpile at the north end of the road corridor beyond the edge <br />of the 35-foot road disturbance area, and topsoil from the pad area will be placed in a stockpile within the shaft pad <br />on the southwest edge of the pad for future reclamation use. The topsoil salvage volumes are indicated on Table <br />49A. Natural vegetative materials (mulch) incorporated into the topsoil, and seeding with the topsoil stockpile <br />stabilization seed mixture identified on page 2.05-121 will stabilize the stockpiled topsoil. <br />TR09-66 2.05-84.8 04/11/09 <br />
