Located in the Sierra Nevadas, the 75 acre Brownfield site once contained two large gold mines during the 1800's Gold Rush. Later the site became a sawmill and plywood plant. The mining waste rock and industrial chemicals, such as PCP, fuel spills and wood treating chemicals, used over the years demanded mitigation efforts for environmental restoration.
