' Banks and gesso, LLC <br />1 (b) Earthmoving Operations <br />' Earthmoving operations will begin with general site cleanup, removing fences <br />and incidental agricultural refuse, with appropriate disposal methods. Trees, <br />shrubs and other excess vegetation will be grubbed and removed, prior to <br />' stripping operations. 1'he topsoil first stripped will be initially stored and stockpiled <br />for future reclamation. Stockpiles remaining for over one year will be planted with <br />the temporary seed mix referenced in Table E-3. During subsequent stripping <br />operations, the Applicant will spread topsoil stripped from one area directly on <br />other areas being concurrently reclaimed. <br />Since the site will be reclaimed as a water storage reservoir, excess topsoil will <br />be sold and weathered shale materials excavated from the pit floor will be utilized <br />as slope backfill materials in Area 1, whenever possible. <br />1 <br />Water Diversions and Impoundments <br />' Stormwater from all areas of surface disturbance will be directed toward the <br />mine's dewatering systems, by grading and shallow ditches. After the water is <br />' clarified and the sediments collected, the water will be discharged to the South <br />Platte River. A CPDS permit will be obtained for the dewatering operations. <br /> <br />1 <br /> <br /> <br /> <br />1 <br />1 <br />Aggregate processing water will be separate from the dewatering and stormwater <br />systems. With evaporation and product moisture losses, there should be no <br />need to discharge processing water. Moreover, some dewatering discharges will <br />be diverted back to the; processing water system. The silt pond at the southern <br />end of the property will be maintained below existing grades, so that any <br />precipitation will be retained in this area. <br />Dewatering quantities will increase as the initial excavation enlarges and <br />approaches the river, before the first phase of the clay liner is constructed. The <br />quantities of groundwater pumped should then decrease, with gradual increases <br />occurring as the mining area expands again. The Applicant will secure outside <br />sources of water to account for losses in the aggregate processing operations. <br /> <br /> <br />Speer Mining Resource <br />Asphalt Specialties Company.
