Emergency Permit for Management of Hazardous Waste, Vallecitos Nuclear Center Decommissioning Project, Sunol, California

The California Department of Toxic Substances Control (DTSC), pursuant to authority granted under California Code of Regulations (CCR), Title 22, Division 4.5, Chapter 20, Sec. 66270.61, has issued an Emergency Permit to Vallecitos Nuclear Center Decommissioning Project (EPA ID# CAL000503509) to treat hazardous waste through a controlled reaction with a chemical solution. Specifically, one (1) 25-gram container of Dipicrylamine must be stabilized prior to transport to an authorized hazardous waste treatment, storage, and disposal facility. This chemical is currently being stored at the Vallecitos Nuclear Center Decommissioning Project located at 6705 Vallecitos Road Building 102, Sunol, California 94586. DTSC has determined as a safety precaution to prevent an accident or severe injury, an Emergency Permit should be issued to chemically stabilize the hazardous waste prior to storage and eventual transportation off-site. Background: Shock and/or temperature sensitive materials can decompose or detonate with external energy when dry or concentrated. If the material is improperly handled, there is a potential for a reaction, which includes fire, deflagration, or detonation. Due to the presence of temperature/shock sensitive materials, DTSC considers these chemicals to be an imminent and substantial endangerment to human health and the environment. Chemical stabilization is recommended prior to transport to a permitted treatment, storage, and disposal facility. Project Activities: The treatment of this hazardous waste involves the addition of a solution to the container in a controlled manner to reduce the reactive or ignitable characteristics of the chemical. Treatment will take place within a designated exclusion zone. Only technicians from Clean Harbors will be allowed in the exclusion zone. Movement, preparation, and treatment of the containers will be in accordance with established standards.
