CM0001504 <br />STAFF REPORT: Climax Mine File No. 1041-0072 <br />BoCC Hearing Date: June 24, 2008 <br />E <br />Construction activities will be conducted in accordance with the Climax Mine Stormwater Management <br />Plan developed in compliance with the General Stormwater Permit for the Site. Best Management <br />Practices (BMPs) to be implemented include: the installation of engineering controls such as silt fencing <br />or straw bale checks to minimize the transport of sediment and control erosion; revegetation of all bare <br />soil areas exposed during construction, unless the disturbed area is intended as a driving surface; the <br />conduct of weekly inspections by Climax personnel; and the proper management of all petroleum <br />products or other potentially hazardous materials used during construction. Climax has an extensive <br />seep collection system and safeguards in place to assure protection of Eagle Park Reservoir. <br />[+] FINDING: (15) Surface water quality, The Project WILL NOT significantly degrade surface water <br />quality. <br />(16) The Project will not significantly degrade groundwater quality. <br />Groundwater issues at hard rock mine sites are regulated by the Colorado DRMS and a monitoring plan <br />for the site has been developed in accordance with the Climax permit requirements. <br />[+] FINDING: (16) Ground water quality, The Project WILL NOT significantly degrade ground water <br />quality. <br />• <br />(17) The Project will not significantly degrade wetlands and riparian areas. <br />The Project is located within the perimeter of the interceptor ditch system. The entire area beneath the <br />Climax site's freshwater interceptor ditches are classified as affected lands, as described in the DRMS <br />Mine Reclamation Permit. <br />The proposed pipeline routing will follow a corridor along an existing road within the affected lands of the <br />Site and will not cross, impact, or significantly degrade any wetlands or riparian areas. <br />[+] FINDING: (17) Wetlands and riparian areas, The Project WILL NOT significantly degrade <br />wetlands and riparian areas. <br />• <br />(18) The Project will not significantly degrade terrestrial or aquatic animal life or its habitats. <br />The Project area is located in an area previously disturbed by mining operations and industrial activity. <br />Based on previous surveys and evaluations of the area, no State or Federally listed threatened or <br />endangered species will be affected by the Project. The proposed construction does not impact any <br />winter range or migration corridors for big game. The Project will not significantly deteriorate terrestrial <br />animal life or its habitat and no aquatic animals or habitat will be impacted. <br />Staff Report Date: 06.24.08 Eagle County Community Development <br />Page 7 of 11
