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- Right. 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
<br />existing disturbance areas (mine facilities and railroad construction). The proposed 2MN drill pad and access road
<br />is in an area previously disturbed by mining- related activities, however, some soil materials remain in this area. For
<br />the drill pads, pipeline, and access roads, available soil materials will be salvaged and stockpiled for use in site
<br />reclamation. Small temporary soil stockpiles will be established adjacent to the pad areas for the limited soil
<br />(estimated at approximately 300 cy at each site) from the borehole pads and roads.
<br />19RT Mine Dewaterina Borehole and Pipeline - Given the proximity of existing ranch roads, TCC does not plan
<br />or anticipate the need for new road construction to access the 19RT Dewatering Borehole drill -site. With dry
<br />ground conditions, drilling equipment and supplies should be able to travel the short distance overland from the
<br />existing roads to the drill -site, without significant surface disturbance. Both the shaft pad and pipeline corridor are
<br />located in an upland areas. For both the shaft pad, and along the 6,200 -foot pipeline corridor, construction will
<br />involve removal of any large vegetation and stripping and stockpiling of other vegetation, soil, and organic
<br />materials. Given an average soil depth of approximately 6 inches in the upland areas, a pad area of approximately
