Revised May, 1987 <br />to the reference area when the H totaled from the four (4) species from <br />• the revegetated area contribute 48 percent to the calculated total H <br />from the revegetated area. <br />Pre May 3, 1978. All areas disturbed prior to May 3, 1978 will be <br />returned to a rangeland/wildlife land use. Areas disturbed prior to May <br />3, 1978 will be deemed successfully revegetated when the cover of these <br />areas is 30 percent or greater. This is based on the cover data that <br />was obtained during the 1983 sampling period. In addition, a letter <br />from the local Soil Conservation Service (SCS) office or other <br />reclamation experts stating, "The revegetated areas are capable of being <br />utilized per their post-mining land use", will serve as documentation <br />that the area has been successfully revegetated. <br />Protection of Hydrologic Balance <br />All drainage and sediment control ditches and ponds will remain intact <br />• until revegetation has been deemed a success at the Williams Fork Strip <br />Pit. Once revegetation has been deemed a success, sediment control <br />ponds will be backfilled and regraded to blend in with the natural <br />topography. Topsoil which was salvaged during the construction of the <br />structures will be used to cover the affected areas to a minimum depth <br />of six (6) inches. The area will be seeded with the seed mixture <br />provided on Table 1, Williams Fork Strip Pit Seed Mixture, and the area <br />returned to the appropriate land use. Straw mulch will be applied to <br />the area at the rate of two tons per acre. <br />Reclamation Timetable <br />The reclamation timetable for all reclamation activities proposed for <br />the Williams fork Strip Pit are presented on Figure 1, Williams Fork <br />Strip Pit Reclamation Timetable. <br />u <br />-8- <br />
