Document Description
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 Decommissioning Project, (EPA ID# CAR000375691) 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 Vallecitos Nuclear Center Decommissioning Project located at 6705 Vallecitos Road, B102, Sunol, California 94586. DTSC has determined as a safety precaution to prevent an accident or severe injury, an Emergency Permit should be issued for to chemically stabilize the hazardous waste by Advanced Chemical Transport LLC (ACT), DBA Republic Services Inc. (ACTenviro) prior to storage and eventual transportation off-site.
Background: Temperature and shock-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 or shock sensitive materials, DTSC considers this chemical 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 the hazardous waste to a solution 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 ACTenviro will be allowed in the exclusion zone. Movement, preparation, and treatment of the containers will be in accordance with established standards. Within 10 business days of the expiration of this permit, Vallecitos Nuclear Decommissioning Project will submit a final report, signed in accordance with Title 22, CCR Sec. 66270.11(d). The report shall include certification that the treatment area has been cleared of all residual hazardous waste generated from this emergency treatment and all generated waste has been properly managed. The Emergency Permit is effective beginning June 25, 2026 and shall expire on September 23, 2026.
