Spill Release Reporting
HAZMAT SPILL NOTIFICATIONS CALL THE STATE WARNING CENTER 1-800-852-7550
In California, any significant release or threatened release of a hazardous material requires immediate reporting by the responsible person to the Cal OES State Warning Center (800) 852-7550 and the Unified Program Agency (UPA) or 911. The UPA may designate a call to 911 as meeting the requirement to call them.
Notifying the State Warning Center (800) 852-7550 and the UPA or 911 constitutes compliance with the requirements of section 11004 of title 42 of the United States Code regarding verbal notification of the SERC and LEPC (California Code of Regulations, Title 19 Section 2631 (e).
Comprehensive Environmental Response, Compensations, and Liability Act (CERCLA), Emergency Planning and Community Right-to-Know Act (EPCRA) and California law require responsible parties to report hazardous material releases if certain criteria is met.
CERCLA requires that all releases of hazardous substances (including radionuclides) exceeding reportable quantities be reported by the responsible party to the National Response Center (800) 424-8802. Additionally, CERCLA provides a reduced reporting requirement for continuous releases of hazardous substances that exceed the Reportable Quantity (RQ). Notification of continuous releases that equal or exceed the RQ need only be given once, with one follow-up report on the first anniversary of the initial report, following the continuous release reporting process. Thereafter only “statistically significant increases” need be reported. The purpose of the continuous release mechanism is to reduce unnecessary release notifications for releases of hazardous substances.
If an accidental chemical release exceeds the EPCRA applicable minimal reportable quantity, the facility must notify State Emergency Response Commissions (SERCs) and Local Emergency Planning Committees (LEPCs) for any area likely to be affected by the release and the National Response Center (800) 424-8802, and provide a detailed written follow-up as soon as practicable. Information about accidental chemical releases must be made available to the public.
