Chapter II <br />When the topsoil is used to reclaim a disturbed area, it will be distributed over the <br />_• area in depths appropriate to the type of material being covered, subject to the <br />availability of material. <br />Soil types, chemical characteristics, and salvage depths (generally from 6 to 14 <br />inches) are covered in detail in Section G, Chapter III, Soils Resource Information. <br />In general, the steep slopes of Coal Basin have little topsoil, and depths of soils are <br />usually quite shallow. In many places, the underlying Mancos shale is exposed. <br />Primarily A and B horizon materials have been salvaged. The horizons are almost <br />indistinguishable as they occur in Coal Basin. <br />Exhibits II-B-4, II-B-7 and revised Exhibits 11-B-App.7-Att.1, Plates 1 and 5-1, indicate <br />the locations of topsoil sites. Exhibits III-G-1, III-G-2 and III-G-3 are soils maps for <br />Coal Basin, the Adit/Rock Tunnel refuse pile area and the Sutey pile area. <br />EXISTING TOPSOIL STOCKPILES <br />Sutey Refuse Disposal Site (1) (2)* <br />Old Refuse Pile (1) <br />Adit/Rock Tunnel (2) (1)* <br />#1 Portal Ponds (2) <br />Overland Conveyor (1) <br />District Office (2) <br />The topsoil storage piles have been seeded. <br />* Additional storage sites have been approved. <br />b. Topsoil Storage -1988-1993. <br />During the permit term, little additional surface disturbance is anticipated, other than <br />that resulting from expansion of the coal refuse disposal area. <br />Prior to expansion of the refuse pile, topsoil and subsoil, as required by MLRD, will <br />be salvaged and stored. <br />The procedure for topsoil salvage is as follows: <br />- vegetation is cleared prior to topsoil salvage; <br />- topsoil is removed to recommended depths; <br />(average depth in Coal Basin is 6 to 14") <br />- topsoil is kept separate from other materials, such <br />as rocks, stumps, etc.; <br />34 <br />
