| Objectives | The Sliger Mine is located in the El Dorado County, approximately nine miles northeast of the intersection of Interstate 80 and State Route 49 and six miles northeast of the City of Cool. The mine is on steep banks above the Middle Fork of the American River. The mine was acquired by the U.S. Bureau of Reclamation as part of the land for the proposed Auburn dam site. This Order regulates the discharge of liquid wastes from the portal discharge only. The Discharger has other regulatory requirements for stormwater and solid wastes, which must be covered under waste discharge requirements. Mines are industrial facilities as defined under the Federal Stormwater Regulation, 40CFR Parts 122, 123, 124. The mine site has a significant amount of tailings exposed to stormwater flows. The State Water Resources Control Board has adopted General Waste Discharge Requirements for industrial stormwater activities. The direct discharge of storm water from the mine site to surface waters is prohibited except as allowed by the General Permit for Disharges of Storm Water associated with Industrial Activities, or an equvalent NPDES permit. |
