Emergency Permit for Management of Hazardous Waste, City of Los Angeles, Department of General Services, Los Angeles, California

Project 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 City of Los Angeles, Department of General Services (EPA ID# CAD981576077) to treat hazardous waste through a controlled reaction with a chemical solution. Specifically, two (2) 1-liter containers of Diethyl Ether must be stabilized prior to transport to an authorized hazardous waste treatment, storage, and disposal facility. This chemical is currently being stored at the City of Los Angeles, Department of General Services located at 2319 Dorris Place, Los Angeles, California 90031. 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: The containers have peroxide formation present on either the inside, outside, or the bottom of the chemical’s containers, as well as the thread container caps. The presence of peroxide formation may be unstable at relatively low concentrations, resulting in fire and/or explosion if improperly handled. Due to the presence of peroxide formation, 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 these hazardous wastes involves the addition of a solution to the containers 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. Within 10 business days of the expiration of this permit, the City of Los Angeles, Department of General Services 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 August 19, 2026 and shall expire on October 19, 2026.
