Order on Consent for Interim Response Action at the RMHF Complex
Document Type
NOE - Notice of Exemption
Document Description
The purpose of this project is to remove the above ground portions of the Radioactive Materials Handling Facility Complex (RMHF Complex or Site) at the Santa Susana Field Laboratory (SSFL) as soon as possible so that contaminants released after potential fire and erosion do not migrate to surrounding communities and the environment. This will be accomplished through the United States Department of Energy's (DOE) performance of closure activities under an Order on Consent for Interim Response Action (Order) issued by the Department of Toxic Substances Control (DTSC). The Order governs DOE's closure activities that will remove the radiological components and chemical hazardous substances associated with above-grade buildings and structures at the RMHF Complex. To achieve these goals, DOE will conduct building demolition activities to slab-on-grade under DTSC oversight and will dispose of the resulting building demolition debris at a licensed low-level radioactive waste disposal facility or authorized mixed low-level radioactive waste disposal facility located outside the State of California. All response actions shall be performed in a manner consistent with the requirements of Chapters 6.8 (commencing with section 25300) and 6.5 (commencing with section 25100) of Division 20 of the Health and Safety Code, and any other applicable state or federal statutes and regulations. See NOE for Full Details
