Phase and Acreage Phase 1 = 19 acres Phase 2 = 10 acres Phase 3 = 19 acres Mining Period ± 15 years ± 15 years ± 15 years Trees, mostly Pinyon and Juniper, and sparse rangeland are found in this section of land. The few trees that will be cut will be utilized for firewood by the owners. Tree replacement will occur at the rate of 1 seedling tree per ten (10) square feet of forested area disturbed with the actual replacement occurring during or after mining, whenever possible. For the majority of the area to be affected, little topsoil was salvaged from the older workings. Topsoil will be salvaged and stockpiled for reclamation as the pit is expanded in the indicated direction. Topsoil in this area averages 4 to 8 inches in thickness. The topsoil will be stockpiled around the perimeter of the affected area as noted on the Exhibit C map. As a stabilization method, any topsoil which is to remain in a stockpile longer than one growing season will be broadcast seeded with a perennial sod-forming grass cover such as Western Wheatgrass at a rate of 20 pounds per acre. Conventional equipment will be used for mining the material: D-7 or D-8 dozer, crusher, 966 front end loader, hydraulic backhoe and haul trucks. The material is either mined or removed as pit run or sized by crushing and stockpiled. Various product stockpiles are created for future sales or processing through the batch plant. There may be from time to time, a portable scale house to weigh the trucks and a portable water tank to supply any water needs at the site. In addition a portable hot mix asphalt plant may be utilized on the site. Final reclamation will occur upon completion of mining. However, slope work, soil replacement and re-seeding will occur concurrently with mining as work in the various phases is completed. The intention is to reduce any chance of erosion occurring on the disturbed area. To facilitate this and prevent stormwater runoff, a 2-3 foot high by 10-15 wide berm will be left at the top of the downhill slope that fall into the canyon. As much as possible, mining operations will henceforth leave any native vegetation in these areas. Normal drainage will be slowed and released into the established drainageways. A stormwater permit is being applied for with the Colorado Department of Health.
