During subsequent <br />stripping operations, 'the Applicant will spread topsoil stripped from one area <br />directly on other areas being con-currently 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, whenever possible. <br />Water Diversions and Imaoundments <br />Stormwater from all areas of surface disturbance will directed toward the mine's <br />dewatering systems, by grading and shallow ditches. After the water is clarified <br />' and the sediments collected, the water will be discharged to the South Platte <br />River. A CPDS permit will be obtained for the dewatering operations. <br />' Aggregate processing water will be separate from the de-watering and <br />stormwater systems. With evaporation and product moisture losses, there <br />should be no need to discharge processing water. Moreover, some de-watering <br />discharges will be diverted back to the processing water system. The silt pond at <br />the southern end of the property will be maintained below existing grades, so that <br />any precipitation will tie retained in this area. <br />1 <br /> <br />1 <br />1 <br /> <br /> <br /> <br /> <br />1 <br />1 <br /> <br />De-watering quantities will increase as the initial excavation enlarges and <br />approaches the river, before the first phase of the slurry wall is constructed. The <br />quantities of groundwater pumped should then decrease, with gradual increases <br />occurring as the mining area expands again. When the final phase of slurry wall <br />construction is completed, the dewatering quantities will once again decrease <br />and continue to do so until the residual groundwater in the deposit is pumped <br />out. While the amount of seepage allowed by the State Engineer's performance <br />standard could be more than double the annual net evaporative loss, we <br />anticipate a net loss of water between seepage and evaporation, on an annual <br />basis. The Applicant will secure outside sources of water to account for losses in <br />the aggregate processing operations. <br />Timetables for Mining and Reclamation Operations <br />The mining and the start of reclamation operations anticipated by the Applicant, <br />dependant on market demand are summarized below: <br />Phase `(ear Mining in <br />Area Mined <br />Acres Reclamation <br />in Area <br />1 1-5 1,3 28.8 1,3 <br />2 6-7 2,3 6.2 1,3 <br />3 8 NA NA 1 & 2 <br />Speer Mining Resource <br />Asphalt Specialties Company, Inc <br />99035 <br />February, 2000 <br />
