EXHIBIT G-1 - WATER INFORMATION NARRATIVE (CONTINUED) <br /> In summary, the estimated water consumption prior to the start of the wet mitring is as follows: <br /> Type of Use Annual Consumption (acre feet) <br /> Evaporation 5.0 <br /> Product and wash water 26.0 <br /> Total 31.0 <br /> The water consumption from evaporation will be 2.5 acre feet for each acre of water exposed for wet <br /> mining. <br /> When reclaimed, up to a 120+ acre surface area lined reservoir, and up to a 22 acre surface area <br /> unlined lake, will occupy the site. No water will be consumed by the liner reservoir. Therefore, no <br /> augmentation plan will be required for the lined reservoir, but up to 55 acre feet of water will be <br /> required to replace evaporative losses from a maximum size 22 acre unlined surface lake area, located <br /> east of the Bull Seep Ditch. <br /> Project Water Supply <br /> Water for washing at the Thornton Plant is being pumped from the alluvium. water consumed by this <br /> process will be replaced by senior water tights within the substitute water supply plan. The applicant <br /> owns approximately 700 acre feet of senior water rights in the South Platte River drainage. These <br /> rights will be used to augment the depletions caused by the mining operations. In addition, the <br /> applicant currently leases effluent from the City of Thornton and Centennial Water and Sanitation <br /> District for replacement to winter time depletions. Prior to exposure of ground water a well permit <br /> and substitute supply plan was applied for from the State Engineer. This plan will provide a detailed <br /> account of depletions and replacement sources. <br /> NPDES Permit <br /> As mentioned prior, water discharge from areas either within or outside the slurry wall, will be <br /> pumped to either two small lakes along 88th Avenue that Cooley also owns, to the Bull Seep Ditch <br /> which traverses a portion of the property, or into the South Platte River. Permission from the owner <br /> of the Bull Seep Ditch(Fulton Ditch Company) will be obtained if the water is discharged to the Bull <br /> Seep Ditch, as will amending the existing, approved NPDES Permit currently in use for the South <br /> Dahlia Pit for this operation, which would use the same discharge point. <br /> Page '), EXHBIT G-1 <br />
