§2.04 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR INFORMATION ON ENVIRONMENTAL RESOURCES. <br />• 2.09.9 Soils Resource Information <br />(1) In general, the soils within the permit area are deep, well drained, and <br />vary widely in slope. Permeability values are low, thus encouraging <br />surface runoff; as a result, the water erosion hazard is often high. <br />Generally available water capacities are high, reflecting the potential of <br />these soils to store water for plant use. Topsoil layers are shallow, <br />ranging from about two to eight inches; surface textures are generally <br />foams or clay foams which subsoils range from clay to foams to clays. <br />Basaltic cobbles and stones are common throughout the profiles of most <br />soils. <br />Although only soils information for those portions of the permit area <br />disturbed by surface operations and facilities is required, the operator <br />submits soil resource information on the entire permit area. This assists <br />in characterizing the environmental resources of the permit area more <br />completely. <br />Soil delineations for the mine area and adjacent lands are shown on Map <br />9-3. A conversion legend is also shown in Table 2.04-19 in the Soils <br />Appendix, Volume 9. Soil descriptions for each mapping unit are given <br />along with site specific soils analysis sheets for the area at the mine <br />and the loadout area in the Soils Appendix. The capability classification <br />groups of soils, as identified on the site specific soils analysis sheets, <br />are also shown in the Soils Appendix. <br />As stated in Sec t ion 2.05. 3 (3 ) (b) Operations Plan, earthwork <br />development began at Bowie No. 1 Mine during October, 1975. Major <br />excavation work on the mine site was completed by mid 1976. During this <br />time the benches, as shown on Map 8-1, were constructed. <br />At that time no regulation governing the removal, stockpiling and <br />replacement of topsoil was in effect. Because of the extremely steep <br />slopes of the mine site, no topsoil was removed, stockpiled or replaced. <br />Although no topsoil was replaced, revegetative efforts to date have been <br />successful. <br />The areas constructed under the interim regulations were: diversion <br />channel, sedimentation ponds, old waste disposal area, and <br />pipeline/powerline. With great difficulty Colorado Westmoreland did <br />remove, stockpile and replace topsoil within <br /> <br />/~')2-lo S <br />/iPPRo~E~ <br />6/z,9/pH <br />Revised 08/01/84 <br />Revised 10/12/86 <br />Revised 10/01/87 <br />Revised 9/21/01 <br />67 <br />
