Emergency Permit for Management of Hazardous Waste, Thermo Fisher Scientific, Pleasonton, California

The California Department of Toxic Substances Control (DTSC) has issued an emergency permit to Thermo Fisher Scientific at its Pleasanton, California facility to chemically stabilize four 4-liter containers of tetrahydrofuran containing hazardous peroxides, which pose an imminent risk of fire and explosion due to chemical instability. This action, authorized under California Code of Regulations Title 22, Division 4.5, Chapter 20, Section 66270.61, is not a procurement but a regulatory emergency response aimed at mitigating a direct threat to public safety and the environment. The stabilization work must be conducted by Clean Harbors Environmental Services within a designated exclusion zone at the site located at 6055 Sunol Boulevard, and the treatment must render the material safe for transport to an authorized hazardous waste disposal facility. The permit is effective from August 11, 2025, to October 9, 2025, with no provision for extension without reauthorization. A final certification report, signed in accordance with CCR Title 22 Section 66270.11(d), must be submitted to DTSC within ten business days of permit expiration, confirming that all residual waste has been properly managed and the treatment area cleared. No federal contracting mechanisms, such as FAR clauses, pricing, or procurement structures, apply; the action is driven solely by state regulatory authority under emergency exemptions to environmental review requirements. The DTSC retains oversight, with Alejandra Cruz designated as the approving official, and only Clean Harbors personnel are permitted to perform the stabilization work. Packaging, labeling, and barcoding requirements are not detailed beyond compliance with general hazardous waste handling standards, and no formal invoice or payment processes are defined.
