Runoff is <br />not ctcpcelcd to be a major problom due to the highly pervious nsturc of the dredge rack. "1'ho County's <br />concern is lhnt erosion and runoff be controlled co that the phosphorus londing that omurs downstream and <br />in Dillon Reservoir is minimized. The proposed runoff wntainmcnt measures in tho plan should be adequate. <br />Section 306 0[ the Goan Wetcr Acl requireanew source performance standards and monitoring rcquirentcnts. <br />The plan slates that tho mining operation will wmply wish all applicable federal and state water quality laws <br />end regulations. Ilowovcr, there is no information oa standards and monitoring. <br />CL'IZCIJ,: Any (CERCLA) ComprehensiveEnvironmcntal Response Compensation and liabilityAcl sites <br />within one mile of the operation must be identified. No mention of the exislcncaor non cxisicnceof these <br />sites is inducted. <br />'lhc County also is wncerned wish the local land use impacts of this operation. County zoning regulations <br />will require Alpine Itodt Company to obtain a wnditional use permit prior to any gravel crushing, asphalt <br />plant or wncrctc plant operation. We understand that the Division of Minerals and Geology and thu Minod <br />land ]toclamation Board have no outhority ovor local land use impacts, nor is there any authority to hold up <br />or deny tho reclamation permit pending the County's approval of a wnditional use permit. We arc not <br />opposed to a gravel mining operation in this area provided that impacts can be adcquatcy mitigated. <br />Iiowcvcr, wo feel strongly that the Division of Mincralsand C,wlogy and the Mined land Reclamation Board <br />should lake a strong stand and require rcelamation to the historic natural wndilion. <br />Sincerely, <br />Steve Hill <br />Community Development Director <br />tx: IIoard of County Commissioners <br />Upper Bluc Planning Comatission <br />Mike Claffcy, Corps of Dnglneers <br />Miko long, Division o[ Minerelc and Geology <br />Mined I and Rcelamalioa Doard <br />Dob IIisgnrd, Alpino Rock Company <br />Sam McClencghan <br />f::V1ilAM,artr16 <br />
