An EPA cleanup plan for the 160-acre Sulphur Bank Mercury Mine Superfund site was released to the public for review and comments. The plan focuses on cleanup in Clearlake Oaks, specifically the mine area, the sovereign territory of the Elem Indian Colony Tribe and contaminated soils in the residential area to the southwest of the site.
Since the site was placed on the Superfund cleanup program in August 1990, the EPA has completed eight early cleanups in an attempt to protect human health and the environment and reduce contamination in soil, lake water and sediments, fish and wildlife, and tribal and residential properties near the mine.
The cleanup plan is open for public comments until April 10, 2023. The EPA will host virtual Q&A sessions, in-person open houses, and in-person final meetings in the coming months.
