ETEC
Welcome to the U.S. Department of Energy (DOE) website for cleanup at the Santa Susana Field Laboratory (SSFL). Our agency mission is to make sure that the land that held the former Energy Technology Engineering Center (ETEC) in Area IV at SSFL is cleaned up so that it is safe for future use.
This site includes resources about the history of the site, the extensive analysis conducted by multiple agencies, and the current state of remediation.

About ETEC
SSFL is located in eastern Ventura County, California, close to the cities of Simi Valley, Chatsworth, West Hills, and Woodland Hills. The site is comprised of four distinct operational areas with two adjacent undeveloped properties.
Characterization & Cleanup
DOE recognizes that there is contamination onsite that needs to be addressed and removed. Through comprehensive analyses and studies, DOE has mapped where the contamination is located and is working with the state to finalize cleanup plans.
Community
DOE is committed to an open and transparent cleanup process of Area IV and public participation is a crucial part to this process. DOE has worked extensively with the community to review onsite conditions through a series of programs and events in addition to quarterly newsletters.
Environment & Health
SSFL neighbors several local communities and serves as a habitat for native plants and animals. While extensive analysis by federal and state agencies shows communities near Area IV are safe, there is contamination onsite that needs to be addressed. Learn about environmental monitoring, cultural and biological studies, engagement with local communities, and former worker health and safety.
