Document Description
The project is the adoption of a National Pollutant Discharge Elimination System (NPDES) permit to regulate the discharge of mine drainage from the Washington Mine. This is an existing underground gold mine which has been in intermittent operation since 1852. Historic, on-going mine drainage from mine portals contains elevated concentrations of natural minerals, including arsenic, has been entering Scorpion Gulch and French Gulch for decades. A water treatment system and conveyance pipelines will be constructed to collect and treat on-going and new discharges of mine drainage from the underground workings prior to discharge to surface waters. The collection and treatment of the historic and proposed mine drainage may improve current surface water quality. The proposed NPDES permit will contain requirements to assure the protection of water quality.
