Document Description
The Department of Toxic Substances Control (DTSC) is in the process of approving the Argonaut Mine Tailings Site Feasibility Study/Remedial Action Plan (FS/RAP) for stormwater management immediately downstream of the Argonaut Dam (proposed project site) located in Jackson, California. The Proposed Project Site is located in the City of Jackson at the intersection of Argonaut Drive and Sutter Street. The Project would convey stormwater to Jackson Creek following the retrofit design of the Eastwood Concrete Multiple Arch (CMA) Dam located on the Argonaut Mine Site in Jackson, California. The Concrete Multiple Arch Dam, also known as the Argonaut Dam, was built in 1916 and stands 46 feet in height and spans over 400 feet in length. Argonaut Dam was constructed as part of a historical gold mining operation and has impounded arsenic-contaminated mine tailings as a result of sediment runoff from more than 50 acres of private land in the city of Jackson. The project aims to provide conveyance of stormwater to Jackson Creek. Activities associated with the Feasibility Study/Remedial Action Plan would occur over an approximately 3-month period.
