SSFL Site Activity Overview
The Department of Toxic Substances Control (DTSC) oversees a comprehensive environmental investigation, monitoring and cleanup program of contamination at the Santa Susana Field Laboratory (SSFL).
Site Operations and History
The Santa Susana Field Laboratory (SSFL) site consists of four administrative areas used for research, development, and test operations as well as buffer zones. The 2,849-acre site is located in the Simi Hills area of Ventura County, approximately 30 miles northwest of downtown Los Angeles. SSFL is between 1,640 and 2,250 feet above sea level, overlooking Simi Valley to the north and northwest and the San Fernando Valley to the southeast.
It is jointly owned by Boeing and the National Aeronautics and Space Administration (NASA), and is operated by the Rocketdyne Propulsion and Power Division of Boeing. A small portion of the Rocketdyne-owned property is leased to the U.S. Department of Energy (DOE). As mentioned, there are four administrative areas, and undeveloped buffer areas:
Surface Water Monitoring: The Los Angeles Regional Water Quality Control Board (RWQCB) is the lead agency responsible for regulating surface water discharge activities at SSFL. To learn more, please visit the RWQCB Web site or visit the Other Agencies page under Regulatory Oversight on this Web site.
Groundwater Characterization and Cleanup: This program consists of ongoing groundwater monitoring of existing wells, sampling of new groundwater locations, and treatment of contaminated groundwater when needed.
Senate Bill 990 (Kuehl): SB 990, effective on January 1, 2008, allows DTSC to clean up the site under the requirements and procedures of the California Superfund Law, and to be enforced under the authority of either the California Superfund Law or the Resource Conservation and Recovery Act (RCRA). The new law gives DTSC the authority to oversee all aspects of the cleanup including both chemical and radioactive wastes, and allows the use of the State Superfund’s risk assessment process for both the radiological and toxic contamination. It also requires DTSC to use the highest and most protective cleanup standards provided under the "rural residential (agricultural)" land use designation.

Resource Conservation and Recovery Act (RCRA): Prior to SB 990, DTSC used the authorities within RCRA to oversee cleanup of the site. As noted above, SB 990 gave DTSC additional authorities to address the unique aspects of this site. Documents on this Web site that were developed under RCRA oversight use the following process:
