No changes in source or use are proposed as part of this Amendment. Notice is provided here of <br /> required changes in permitting since last application. Historically, operations have used three wells to <br /> supply water for domestic and potable use. The three wells used for domestic use (Cross, Cabin, and <br /> Caribou) have been re-permitted as domestic/industrial with the Division of Water Resources, <br /> applications filed May 5, 2021. The well ownership has been changed to Grand Island Resources LLC to <br /> align with water rights ownership. Water rights are provided through a 1/8 share in the Farmers Ditch <br /> Company adjudicated and decreed for use from mine workings in case number W-8261-76. A substitute <br /> Water Supply Plan was filed May 19, 2021 to allow use of W-8261-76 mine workings water from co- <br /> located drilled wells. Supporting documentation is attached. <br /> Operational Water <br /> No changes in source or use are proposed as part of this Amendment. Notice is provided here of <br /> required changes in permitting since last application. Historically, operations have used a pump located <br /> on the 41h level of the Cross Mine for dewatering. Water rights are provided through a 1/8 share in the <br /> Farmers Ditch Company adjudicated and decreed for use from mine workings in case number W-8261- <br /> 76. Dewatering is directed through ponds to Coon Track Creek. Application was made to the Division of <br /> Water Resources to assign a well permit to the Cross Mine Adit dewatering well. This well is being <br /> permitted for industrial supply and dewatering use. <br /> Operational Ground Water Quality Impacts <br /> The waste rock is primarily composed of gneiss and quartz monzonite.These materials are benign and <br /> have been analyzed for leachability and acid production by DRMS-approved methods. The results of the <br /> analyses demonstrated the materials are non-acid producing and non-metals leaching. Due to the <br /> nature of the waste rock generated by mining operations, significant impact to ground water quality is <br /> not expected. <br /> GIR will comply with all applicable ground water standards established by the Water Quality Control <br /> Commission. Appropriate water treatment is being provided at water treatment pond (#1), sufficient to <br /> meet applicable water quality discharge standards, as specified in our CDPES permit. <br /> Surface Water Quality Impacts <br /> As with ground water, surface water quality impacts are not expected. Groundwater exposed from <br /> dewatering is discharged to Coon Track Creek under our CPDES permit. Where needed, appropriate <br /> storm water controls will be implemented during the construction and reclamation of the proposed <br /> activities. <br /> Mine stormwater management is documented under Permit#COR 040242.The mine submits annual <br /> reports on our Storm Water Pollution Prevention Plan (SWPPP) program. As required by regulation,the <br /> current SWPPP, and the supporting Storm Water Management Plan (SWMP) containing sediment and <br /> erosion Best Management Practices (BMPs), are maintained on site for use and inspection. Appropriate <br /> BMP storm water controls will be implemented during the proposed construction and reclamation <br /> 5 <br />
