road extension, approximately 740 CY will be salvaged and stockpiled from the pad. The soil resources
<br />information was derived from information presented in Exhibits 7 and 8, Soil Profile Description and Soil Mapping
<br />• Unit Descriptions, Map No. 19, Mine No. 3, Soils presented in permit C -84 -062. These materials are incorporated
<br />herein by reference. At the bleeder fan site, Twentymile will establish a test pit to verify topsoil depths prior to
<br />salvaging topsoil. The stockpiled topsoil, which is located within the pad area, will be stabilized with the topsoil
<br />stockpile stabilizing seed mixture. Prior to salvaging any topsoil from the site, a T & E species reconnaissance for
<br />Ute Lady's Tresses, Spiranthes diuvialis, will be conducted, and the results forwarded to the Division. It is not
<br />anticipated that this species will be found, as the site appears to be outside of its natural range.
<br />18 Right Ventilation Shaft (TR04 -44)
<br />Approximately 4,400 feet of the access road crosses upland areas, with the remaining 2,700 feet crossing lowland
<br />areas where road construction will involve removal of any large vegetation and stripping and stockpiling of other
<br />vegetation, topsoil, and organic materials. Similarly, the shaft pad is located in an upland area. Given an average
<br />topsoil depth of approximately 6 inches in the upland area and a total road disturbance area of approximately 5.7
<br />acres, approximately 4,600 cubic yards of topsoil will be salvaged from the road corridor, and 2,000 cubic yards
<br />from the 2.5 acre pad area. Prior to initiating topsoil removal activities, stream/wetland buffer zones will be
<br />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 (TR05 -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 />18 -Left Ventilation Shaft Installation and Pipeline (TR09 -66, TR09 -70)
<br />Approximately 420 feet of the light -use road crosses upland areas, where road construction will involve removal of
<br />any large vegetation and stripping and stockpiling of other vegetation, soil, and organic materials. Similarly, the
<br />shaft pad is located in an upland area. In order to reestablish effective vegetative cover, TCC will recover and
<br />stockpile a maximum of 18 inches of soil material from shaft disturbance areas. With a total road disturbance area
<br />of approximately 0.3 acres, approximately 750 cubic yards of soil will be salvaged from the road corridor, and
<br />12,800 cubic yards from the 5.3 acre pad area. The 18 -Left Mine Water Transfer Pipeline will traverse both upland
<br />and lowland areas, and since better soil conditions are found in these areas, soil recovery will be limited to
<br />approximately 12 inches along the pipeline corridor, resulting in recovery of approximately 12, 150 cubic yards of
<br />soil material. The soil salvage volumes are indicated on Table 49A. Prior to initiating soil removal activities,
<br />• temporary sediment control, in the form of wattles and/or silt fences, will be installed downgradient of the road and
<br />pad to control runoff and sediment. Soil materials will be salvaged and placed in two soil material stockpiles. The
<br />stockpiles are located where they will not be subject to vehicle traffic or erosion from runoff, will be stabilized by
<br />seeding with TCC's temporary seed mix, and topsoil signs will be posted.
