These somewhat poorly to poorly drained soils provide wildlife habitat and occur on drainage <br />channels, swales, and low areas and have formed from alluvium and slopewash. <br />The best sources of topsoil material within the New Horizon 2 Mine disturbance area are the <br />708, D70B, 30C (1988 - 1996 disturbance areas), 98D and 98E (1999 proposed disturbance <br />area), soil mapping units. These units (98D and 98E) occupy about 52 percent of the proposed <br />1999 disturbance area. <br />Generally, those soils which have a very high percentage of coarse fragments (greater than 35 <br />percent by volume), very shallow bedrock (0 to 10 inches), and shallow ground water (less than <br />1 to 2 feet), have little suitable topsoil to be salvaged. No topsoil is available to be salvaged from <br />existing roads, ponds, residences, or farmyards <br />Topsoil Salvage Depths - 1988. The suggested salvageable depths of topsoil material <br />presented in this section are based on laboratory data and extensive field observations, and <br />represent only the most suitable sources of topsoil material. No unsuitable sources of topsoil <br />will be salvaged and used during reclamation activities. Table 2.05.4(2)(d)-1 summarizes <br />topsoil salvage depths and characteristics by map unit for the New Horizon 2 Mine disturbance <br />area. It should be noted that the topsoil depths and volumes listed in Table 2,05.4(2)(d)-1 are <br />only estimates derived from field sample pits. Exact volumetrics for each topsoil horizon cannot <br />be determined until actual topsoil removal is accomplished. WFC will live handle the majority of <br />the topsoil with scrapers or a truck/shovel fleet from in front of the active pit to the final graded <br />backfill. WFC is committed to salvaging and redistributing all suitable topsoil. Exhibit 2.05.4-4 <br />shows the anticipated replacement topsoil thickness for each vegetation category. Actual <br />replacement thickness may vary and WFC will document any variations in the Annual <br />Reclamation Report. <br />Topsoil Salvape Depths - 1995. At the conclusion of Phase 6 topsoil removal campaign (12- <br />20-95), WFC conducted a topsoil balance study for the approved permit boundary. The study <br />included the entire New Horizon 2 mining area. The remaining undisturbed acreage that topsoil <br />will be salvaged from plus the topsoil that was placed in topsoil stockpiles at the beginning of <br />mining was taken into account. All disturbed acreages where taken into account. The <br />• (Revised s-ie-zoom 2.05.4(2)(d)- 8 <br />
