Remediation of Area IV and the Northern Buffer Zone of the Santa Susana Field Laboratory

DOE is amending its 2008 notice of intent to prepare an environmental impact statement (EIS) for cleanup of Area IV, including the Energy Technology Engineering Center (ETEC), as well as the Northern Buffer Zone of the Santa Susana Field Laboratory (SSFL) in eastern Ventura County, California, approximately 29 miles north of downtown Los Angeles. (DOE’s operations bordered the Northern Buffer Zone. DOE is responsible for soil cleanup in Area IV and the Northern Buffer Zone.) Since DOE’s 2008 NOI, extensive studies of the site for radiological and chemical contamination have been ongoing and are nearing completion. DOE is proposing a revised scope for the EIS due to the 2010 Administrative Order on Consent (2010 AOC) that DOE and the California Department of Toxic Substances Control (DTSC) signed for soil cleanup, and due to information now available from site characterization. The scope of the EIS would continue to include groundwater remediation consistent with requirements in the 2007 Consent Order for Corrective Action (2007 Consent Order) issued by DTSC. This Amended NOI describes DOE’s proposed action and includes cleanup concepts developed by the local community.
