Emergency Permit for Treatment of Hazardous Waste, HP Inc., San Diego, California

Emergency Permit for Treatment of Hazardous Waste, HP Inc., San Diego, California

Project Description: The California Department of Toxic Substances Control (DTSC), pursuant to authority granted under California Code of Regulations, Title 22, Division 4.5, Chapter 20, Section 66270.61, has issued an Emergency Permit to HP Inc. (HP) (EPA ID# CAD049904766) to treat hazardous waste through a controlled reaction with a chemical solution. Specifically, one (1) Benzoyl Peroxide, three (3) Tetrahydrofuran, two (2) Isobutyl Methacrylate, one (1) Acrylic Acid, one (1) Allyl Methacrylate, three (3) Methyl Methacrylate, one (1) Ethyl Acrylate, three (3) Butyl Acrylate, one (1) Butyl Methacrylate, two (2) t-Butyl Methacrylate, two (2) Styrene, one (1) 4-Vinylpyridine, two (2) Acrylonitrile, one (1) Butyl Glycidyl Ether, one (1) t-Butyl Acrylate, and two (2) Triethyl Orthoformate containers totaling 30.1 liters must be stabilized prior to transport to a permitted treatment, storage, and disposal facility. The hazardous waste items are expired and are currently being stored on the HP Inc. campus located at 16399 W. Bernardo Drive, San Diego, CA 92127. 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 wastes prior to transportation off-site by Clean Harbors Environmental Service (CHES). Background: The chemicals noted above are peroxide forming materials. The chemicals produce peroxide compounds as they degrade (i.e., after the product’s expiration date). The peroxides produced may be unstable at relatively low concentrations, resulting in fire and/or explosion if improperly handled. Static electricity or heating from sunlight may be enough to trigger some reaction, making transport of non-stabilized chemicals hazardous. Chemical stabilization is recommended prior to transport to a permitted treatment, storage, and disposal facility. Project Activities: The treatment of the hazardous waste involves the addition of 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 CHES will be allowed in the exclusion zone. Movement, preparation, and treatment of the items will be in accordance with established standards. Within 10 business days of the expiration of this permit, HP will submit a final report, signed in accordance with Title 22, California Code of Regulations section 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 March 31, 2021 and shall expire on May 29, 2021.
