percent each of Winevada and Coutis inclusions (Appendix 9-2, Table 11. A 6-inch mean salvage depth was used for this map unit to calculate recoverable topsoil volumes listed in Table 21-1 and Exhibit 9-1. This topsoil salvage depth figure accounts for inclusions and topsoil Toss during salvage due to brush clearing. Topsoil salvage within this map unit will onl be conducted if the salvaged topsoil is suitable, the rock fragment content is less than 35 percent, and equipment can be operated safely. 5703-Starman Fine Sandy Loam. This map unit occurs on steep to very steep sideslopes, toeslopes, and ridges. Starman soils have a thin light colored surface horizon which directly overlie skeletal substratum. Adjacent soils are moderately deep (Roxal Variantl, have a dark colored surface horizon, subsurface clay accumulation, and a skeletal substratum ILymansonl, or have an argillic horizon ILithic Cryoboralfsl. The S703 map unit consists of 80 percent Starman with 8 percent Roxal variant, 7 percent Lymanson, and 5 percent Lithic Cryoboralf inclusions (Appendix 9-2, Table 11. A 6-inch mean salvage depth was used for this map unit to calculate recoverable topsoil volumes listed in Table 21-1 and Exhibit 9-1. This topsoil salvage depth figure accounts for inclusions and topsoil loss during salvage due to brush clearing. Topsoil salvage within this map unit will onl be conducted if significant contamination by rock fragments can be avoided and equipment can be operated safely. DL-Disturbed Land (roads, oil well pad, pond embankment, or borrow areal. This map unit is located in areas where prior construction has destroyed, covered, or contaminated the topsoil resource. These areas, including the access road, erection pad, oil well pad, and Twentymile Road, were all disturbed prior to 1976. No suitable topsoil is available from this unit (Table 21-1 and Exhibits 9-1 and 9-21. W-Water. This map unit consists of man-made and beaver pond areas that existed when the baseline soil surveys were completed. No suitable topsoil is available from this unit (Table 21-1 and Exhibits 9-1 and 9-21 Topsoil Salvage Techniques. Before any area at the mine site other than a proposed topsoil stockpile site is significantly disturbed, the suitable topsoil material will be removed to the depth specified in Tables 21-1, and 21- 2, and Exhibits 9-1, 9-2 and 9-3. Life-of-mine topsoil salvage information is presented in Table 21-1, whereas Table 21-2 21 Revised 9198
