Through comprehensive analyses and studies, the Department of Energy has mapped where the contamination is located and is close to finalizing the blueprint for cleaning up the site.
Multiple rounds of sampling by a number of independent agencies have all concluded that there is no offsite threat to human health from DOE’s former operations in Area IV. Extensive assessments have also ruled out any potential pathways for contamination to leave the site.

DOE and the California Department of Toxic Substances Control (DTSC) have been in the field working on the chemical co-located sampling effort with Environmental Protection Agency (EPA).

DOE published a Record of Decision (ROD) outlining planned groundwater remediation activities at the site.

The Resource Conservation and Recovery Act, enacted as federal law in 1976, is the principal law that governs disposal of hazardous waste in the United States.

DOE announced the signing of an amendment to the May 2020 Order on Consent with the State of California to demolish the remaining DOE-owned buildings at the former Energy Technology Engineering Center (ETEC) research site in Area IV of the SSFL.

DOE is releasing the Final Environmental Impact Statement (FEIS) for cleanup of Area IV and the Northern Buffer Zone at the SSFL in Ventura County, California.

Waste from cleanup activities at ETEC was generated from excavated soil, unusable equipment and supplies, and building debris.
