The Teller County Planning Department has completed its review of the Department of Reclamation, Mining and Safety(DRMS) required Technical Revision (TR#79)to pump solution from the High Grade Mill (HGM)to infiltration wells in the Arequa Gulch Valley Leach Facility (AGVLF). Staff understands that as the HGM has undergone commissioning,that it has been necessary to refine the original prediction of the volume of the high pH water and that CC&V is now proposing a deep injection rather than surface drip system as originally proposed. 2. Teller County understands that Mill Fluids that cannot be recycled back into the milling process will be pumped via a 4-inch HDPE pipe to one of two infiltration wells as depicted in the providing figure 1 and Drawing 30-647-501. Further, both the pipeline and the infiltration wells are located inside the existing facilities area (HGM footprint and AGVLF) and that both the facilities and the land are wholly owned by CC&V. 3. Teller County requests that DRMS inform the Colorado Division of Water Resources of TR-79 activity as it relates to the mill fluids being pumped into the two wells for any possible impacts to Teller County aquafers or potential impacts to the water supply the nearby cities of Victor, Goldfield and Cripple Creek.
