percent each of Winevada and Coutis inclusions (Appendix 9-2, Table 11. A 6-inch mean salvage depth <br />was used for this map unit to calculate recoverable topsoil volumes listed in Table 21-i and Exhibit 9-1 . <br />This topsoil salvage depth figure accounts for inclusions and topsoil loss during salvage due to brush <br />clearing. Topsoil salvage within this map unit will o~ be conducted if the salvaged topsoil is suitable, <br />the rock fragment content is less than 35 percent, and equipment can be operated safely. <br />5103-Starman Fine Sandy Loam. This map unit occurs on steep to very steep sideslopes, toeslopes, <br />and ridges. Starman soils have a thin light colored surface horizon which directly overlie skeletal <br />substratum. Adjacent soils are moderately deep IROxaI Variantl, have a dark colored surface horizon, <br />subsurface clay accumulation, and a skeletal substratum ILymansonl, or have an argillic horizon ILithic <br />Cryoboralfsl. <br />The 5103 map unit consists of 80 percent Starman with 6 percent Roxal variant, 7 percent Lymanson, <br />and 5 percent Lithic Cryoboralf inclusions (Appendix 9-2, Table 11. A 6-inch mean salvage depth was <br />used for this map unit to calculate recoverable topsoil volumes listed in Table 21-1 and Exhibit 9-1. <br />This topsoil salvage depth figure accounts for inclusions and topsail loss during salvage due to brush <br />clearing. Topsoil salvage within this map unit will only be conducted if significant contamination by <br />rock fragments can be avoided and equipment can be operated safely. <br />• DL-Disturbed Land (roads, oil well pad, pond embankment, or borrow areal. This map unit is located in <br />areas where prior construction has destroyed, covered, or contaminated the topsoil resource. These <br />areas, including the access road, erection pad, oil well pad, and Twentymile Road, were ell disturbed <br />prior to 1976. No suitable topsoil is available from this unit (Table 21-1 and Exhibits 9-1 and 9-21. <br />W-Water. This map unit consists of man-made and beaver pond areas that existed when the baseline <br />soil surveys were completed. No suitable topsoil is available from this unit (Table 21-1 and Exhibits 9-1 <br />and 9-2). <br />Topsoil Salvage Techniques. Before any area at the mine site other than a proposed topsoil stockpile <br />site is significantly disturbed, the suitable topsoil material will be removed to the depth specified in <br />Tables 21-1, and 21-2, and Exhibits 9-1, 9-2 and 9-3. Life-of-mine topsoil salvage information is <br />presented in Table 21-1, whereas Table 21-2 <br />u <br />21 Revised 9/98 <br />
