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, I I-B-7 and revised Exhibits II-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 />
