Emergency Permit for Management of Hazardous Waste, EMD Millipore Sigma Company, Visalia, California

The California Department of Toxic Substances Control has issued an emergency permit to EMD Millipore Sigma Company to enable the chemical stabilization of hazardous waste at its facility in Visalia, California, under authority granted by CCR Title 22, Division 4.5, Chapter 20, Section 66270.61. The waste, currently stored on-site, includes specific quantities of peroxide-forming chemicals such as Ethyl Ether, Diethyl Ether, Tetrahydrofuran, Ethyl Vinyl Ether, and Styrene, which pose significant fire and explosion risks due to reactive peroxide accumulation. Clean Harbors Environmental Services is authorized to perform the stabilization treatment using a controlled chemical reaction to render the waste non-reactive and safe for transport. The work is restricted to a designated exclusion zone accessible only to trained Clean Harbors personnel, with all activities required to comply with state hazardous waste regulations. The permit is effective from July 28, 2025, through September 26, 2025, and requires submission of a final signed report within ten business days after expiration, certifying that the treatment area has been cleared and all generated waste properly managed. No formal contract pricing, federal acquisition regulation clauses, or procurement structure applies to this action, as it is an emergency regulatory permit issued under state authority rather than a competitively procured contract. The permit does not include identified contract value, funding symbols, invoicing procedures, or payment details, nor does it invoke FAR, DFARS, or MIL-STD requirements. Packaging and marking requirements are derived solely from state hazardous waste labeling standards, and no barcoding, shipping terms, or technical specifications for containers are detailed beyond volume and chemical type. The primary oversight authority is the DTSC, with Michelle Snapp serving as the primary point of contact, while EMD Millipore Sigma Company and Clean Harbors bear operational responsibility for compliance, safety, and post-treatment reporting. The action is exempt from environmental review under state law due to its emergency nature, and no socioeconomic or small business set-asides apply. The sole deliverables are the chemically stabilized waste and the final compliance report, with performance limited entirely to the Visalia site prior to off-site transport to an authorized hazardous waste facility.
