upgrading of the road, approximately 3,600 CY of topsoil will be windrowed to the side of the road. The topsoil
<br />along the length of the road is approximately 30 inches deep. The facility site will require salvaging and
<br />stockpiling approximately 8,300 CY of topsoil. The topsoil from the site area is approximately 30 inches deep. A
<br />test pit will be dug to verify the topsoil depth obtained from previous soil mapping work. The stockpiled topsoil,
<br />which is located within the pad area, will be stabilized with the topsoil stockpile stabilizing seed mixture.
<br />Additionally, approximately 6,295 CY of topsoil will be salvaged from the treatment pond site. This site has been
<br />relocated closer to the road to facilitate delivery of chemicals.
<br />Bleeder Fan - The bleeder fan facility will require salvaging and stockpiling approximately 4,700 CY of topsoil
<br />from the access road and the facility site. During the upgrading of the road, approximately 2,800 CY of topsoil will
<br />be windrowed to the side of the road and left in place. The 1,200 CY that will be salvaged from the road extension
<br />will be placed in the stockpile that will be established on the fan pad. In addition to the topsoil stockpiled from the
<br />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, TC will establish a test pit to verify topsoil depths prior to salvaging
<br />topsoil. The stockpiled topsoil, which is located within the pad area, will be stabilized with the topsoil stockpile
<br />stabilizing seed mixture. Prior to salvaging any topsoil from the site, a T & E species reconnaissance for Ute
<br />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 soil removal, the stream buffer zone will be marked with identifying
<br />signs to prevent surface disturbance within buffer zone areas. The topsoil from the road corridor was initially
<br />windrowed adjacent to the road and topsoil from the pad area was placed in a stockpile adjacent to the shaft pad and
<br />within the road corridor, for future reclamation use. As a result of concerns related to protection of windrowed
<br />topsoil from erosion and contamination, a decision was made to recover topsoil from the windrows and place it in
<br />stockpile. The topsoil salvage volumes are indicated on Table 49A. Seeding with the topsoil stockpile stabilization
<br />seed mixture identified on page 2.05-121 will stabilize the windrowed and stockpiled 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 />6-Ri2ht, 7 -Right, and 2 -Main North Thickener Underflow Borehole and Pipeline Installations
<br />The proposed 6RT and 7RT drill -pads and access road are in areas that have previously been disturbed by County
<br />road construction activities. It is unknown whether soil materials were salvaged and replaced in these areas,
<br />however, a reestablished sagebrush -meadow vegetation community exists over most of the proposed pad and
<br />pipeline areas. The corridor for the proposed thickener underflow pipeline crosses both previously disturbed and
