Environmental Impact Statement (EIS) for Demolition and Environmental Cleanup Activities at Santa Susana Field Laboratory in California

October 2, 2020 – NASA has released its Record of Decision (ROD) for Soil Cleanup Activities at Santa Susana Field Laboratory (SSFL), California. After carefully considering the information and analysis provided in the Final Supplemental Environmental Impact Statement, including the comments received from the public, non-governmental organizations, Native American tribes, and federal, state, and local government officials, NASA’s decision is to proceed with Alternative C, Suburban Residential Cleanup. A Suburban Residential Cleanup would be protective of public health and the environment, follow nationwide EPA guidelines, and is consistent with the cleanup standards imposed by the Department of Toxic Substances Control (DTSC) across the State of California. NASA is eager to move forward with the soil cleanup. NASA can finalize a soil implementation cleanup plan once the California DTSC completes their Programmatic Environmental Impact Report and issues a decision document.
