1.2.3 Colorado Parks and Wildlife (CPW) Statement The proposed modifications will not result in a Designated Mining Operation or significant impacts to wildlife use.The site has been in continuous operation since 1977, and was first permitted by DRMS in 1980. Man-made structures are present across the site to support the mining operation. Wildlife habitat has not been specifically evaluated, but will be evaluated during the summer 2021 season. When this data becomes available it will be forwarded to DRMS. 1 .3 Water Resources 1.3.1 Surface Water Resources Coon Track Creek bisects the proposed permit area.Associated with the drainage are some wetlands on either side of Coon Track Creek. Surface water quality impacts are not expected.Where needed, appropriate Best Management Practice (BMP)storm water controls will be implemented during the construction and reclamation of the proposed activities. No hazardous or toxic chemicals will be used during any of the proposed construction. Stormwater discharge and management is regulated by the Colorado Department of Public Health and Environment(CDPHE)Water Quality Control Division (WQCD) Colorado Pollutant Discharge Elimination System (CPDES). Mine stormwater management is documented under Permit#COR 040242.The mine submits annual reports on our SWPPP program. As required by regulation,the current Storm Water Pollution Prevention Plan (SWPPP), and the supporting Storm Water Management Plan containing sediment and erosion Best Management Practices(BMPs), are maintained on site for use and inspection. Appropriate BMP storm water controls will be implemented during the proposed construction and reclamation activities. No hazardous or toxic chemicals will be used during any of the proposed reclamation construction. No actual stream flow or surface water quality data are available for Coon Track Creek or North Beaver Creek into which Coon Track Creek and Hicks Gulch flow. North Beaver Creek flows into Middle Boulder Creek at Nederland, CO. Stream flow data from Middle Boulder Creek at Nederland, CO, USGS Station ID 06725500 is used below to provide stream flow data. Stream Flow data (shown below)are from the following source: Colorado Division of Water Resources, data retrieved, May 4, 2021. No site-specific surface water quality data is available from the Coon Track Creek. GIR has discussed surface and ground water monitoring programs with the DRMS and is preparing programs to monitor surface and ground water quality.The surface and ground water monitoring programs will be submitted to DRMS as a permit revision separate from this Amendment. 12
