1 .14 Time Limit and Phased Reclamation (Section 3.1 .3) <br /> This is an underground mining operation. Once underground mining is complete and the surface <br /> facilities are no longer needed,the affected mine site surface areas (Exhibit D, Section 1.1)will be <br /> reclaimed within the five-year time period. <br /> Year One: Reclamation will begin with removal of facilities, debris, and other materials (Exhibit D, <br /> Section 1.1)that would interfere with revegetation. Water, sediment, and liners will be removed from <br /> the ponds. Reclamation areas will be graded and prepared for revegetation. If time allows during the <br /> first year of reclamation,the reclamation sites will be revegetated. Revegetation may need to wait for <br /> Year Two: Shafts and portals will be closed and fenced. <br /> 1 .15 Public Use <br /> Other than sanctioned mine tours,the area will not be open to the public.The mine access points <br /> will be gated and appropriately marked stating no unauthorized access is permitted. <br /> 1 .16 Reclamation Measures Materials Handling (Rule 3) <br /> All reclamation measures and materials handling will be conducted in accordance with the Colorado <br /> Mined Land Reclamation Board Mineral Rules and Regulations for Hard Rock, Metal, and Designated <br /> Mining Operations Reclamation Performance Standards, Rule 3. Specific requirements are addressed <br /> throughout the Exhibits in this permit application amendment. <br /> 1.16.1 Impacts to Groundwater and Surface Water <br /> Disturbances to the prevailing hydrologic balance will be minimized by adherence to Colorado Water <br /> Quality Regulations <br /> Groundwater Impacts <br /> The waste rock is primarily composed of gneiss and quartz monzonite.These materials have been <br /> analyzed for leachability and acid production by ORMS-approved methods.The results of the analyses <br /> demonstrated the materials are non-acid producing and non-metals leaching. Due to the nature of the <br /> waste rock generated by mining operations, significant impact to ground water quality is not expected. <br /> Surface Water <br /> As with ground water, surface water quality impacts are not expected. Where needed, appropriate Best <br /> Management Practice (BMP) storm water controls will be implemented during the construction and <br /> reclamation of the proposed activities. No hazardous or toxic chemicals will be used during any of the <br /> proposed construction. Please see Exhibit B, Section 1.7.1. <br /> GIR currently manages and treats one permitted mine water discharge point,which discharges directly <br /> into Coon Track Creek under Colorado Department of Public Health and Environment (CDPHE)Water <br /> Quality Control Division (WQCD) Colorado Pollutant Discharge Elimination System (CPDES) Permit CO- <br /> 0032751. <br /> 13 <br />
