3-5 <br />• <br />That portion of the access road located along the canyon slopes <br />(wildlife habitat) will be reclaimed utilizing a backhoe and <br />bulldozer. trlaterial will be pulled from the downslope and cast <br />into the road area to approximate original drainages, proposed <br />post-mining land use and surrounding land use. <br />Backfilling is discussed in Section 3.3. <br />All grading will be done on the contour where possible. Where <br />such an operation would not provide a safe condition for the <br />equipment operator, quick growing grasses will be established by <br />broadcasting for protection against erosion and siltation. The <br />backfill areas (sealing of drift entries, road work and sediment <br />• ponds) will be roughed on those slopes where equipment can be <br />safely operated in order to provide protection against slippage. <br />3.2 Topsoil Removal and Storage <br />Two soil units occur in the 0.5 acre area of the sediment pond, the <br />~Rivra gravelly sandy loam variant (0.2 acres) and Nihill loam ~ <br />(0.3 acres). Recommended stripping depths are 12 inches and 16 <br />inches, respectively, based on data present in Table 4.7-2. <br />Volumes of topsoil available for stripping and stockpiling have <br />been calculated from the acreage of the soil mapping units percent of <br />strippable soils, and recommended stripping depths. A total of 0.56 <br />acre-feet (900 bcy) of soil will be salvaged from the sedimen <br />. area. <br />~- <br />
