mine water will be discharged into an ephemeral tributary to Bull Canyon, which when flowing, discharges into the Dolores River. The permit requires sampling and analysis for various constituents on a weekly and monthly basis at the discharge point. The permit standards are based on the water quality criteria established by the state for the Dolores River. A Material Containment Plan will also be developed that provides guidance for the storage, use, cleanup, training, and reporting associated with the use of water treatment chemicals onsite. • A solvent - cleaning station may be installed in the maintenance shops. These stations generally consist of a cleaning sink mounted on a small drum of solvent. The solvent is pumped into and used in the sink and then recycled back to the drum via a gravity drain. The drums of solvent are periodically replaced by a vendor that recycles the solvent. If these stations are installed, Cotter will acquire the necessary permit(s) from the Colorado Hazardous Materials and Waste Management Division (HMWMD). The electrical transformers installed by Cotter to be used on site will not contain PCBs. Sludge produced from the water treatment system will be disposed of in accordance with HMWMD's Radiation Management Program's regulations for Technologically - Enhanced Naturally Occurring Radioactive Materials (TENORM). • Cotter will apply for an air emissions permit from the CDPHE for fugitive dust during ore transport and blasting if required. • Cotter has obtained an individual sewage disposal system permit from Montrose County. Permanent facilities have existed on site since 1975. • The project is located entirely on public land managed by the DOE. The DOE requires a mine plan and a reclamation plan prior to beginning a mining operation. • The area of the JD -9 mine is zoned "agriculture" by Montrose County. A Conditional Use Permit for the mine was approved by Montrose County in 1975. The Conditional Use Permit included many of the same environmental protection measures described in this permit application. • Socioeconomic impacts to the local communities will be positive but limited due to the limited number of employees required at the mine. • Cotter will strictly adhere to all MSHA applicable regulations.
