42.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />~_ <br />2.05.4 Reclamation Plan. <br />(2) (d) (Cont'd.) <br />The soils of the OVWM pipeline and 200,000 gallon water <br />tank were identified in the U.S. Soil Conservation Ser- <br />vice, Soil Survey of P aonia, CO, January, 1981, as Del- <br />son stony loam, 3% to 20X slopes. Twelve inches of <br />topsoil was salvaged from the area of the foundation <br />and redistributed over the ground surface adjacent to <br />the tank and seeded. Because the A, B & C horizons of <br />the soils along the pipeline were rated as excellent <br />topsoil medium and the depth of excavation did not ex- <br />ceed the depth of this medium, no separation of topsoil <br />during excavation or backfilling was required. <br />Sampling and analysis of soils in the area of the Or- <br />chard Valley West Mine site was completed in July, <br />1986, by CWI' consultant, Harner and Associates, Inc. <br />Sampling techniques and results are presented in the <br />Soils Appendix, Volume 9. <br />Due to the steep slopes east of East Roatcap Creek and <br />the quantities of stones in these soils, 32 inches of <br />topsoil was salvaged from the area of disturbance west <br />of East Roatcap Creek where Delson soil occurs. <br />The land use goal of the Orchard Valley West Mine site <br />is to produce a permanent, diverse vegetation cover <br />suitable for rangeland and wildlife habitat. To meet <br />these goals, an average depth of 24 inches of topsoil <br />or conditioned soil material would be returned to the <br />reclaimed surface. <br />~ e) <br />Revegetation Plan <br />Revegetation at the Orchard Valley Mine will be accom- <br />plished according to a strict timetable involving soil <br />preparation, seeding with adapted species mix, planting <br />of containerized stock, fertilization, mulching and <br />monitoring of results to achieve a native plant cover <br />consistent with the desired land use goals. <br /> <br />Revised 10/01/87 <br />67 <br />
