Operating Permit

Hazardous Materials (Non-Retail) - Regulated Quantities


Section 255503.5 of California Health and Safety Code (HSC) requires any facility having hazardous materials/wastes onsite, in quantities at or in excess of 55 gallons, 500 pounds and/or 200 cubed feet, for a period exceeding 30 days, to obtain an annual operating permit issued through the CUPA. The HSC does provide program exemptions - specifically for retail operations, dispensing of medical gases (1000 cubed foot limit), and unused lubricating oil (55 gallon limit). Check with the Fire Prevention Division for details on how they may apply.

Within the City of Ventura, an operating permit is issued upon submission and approval of a Hazardous Material Business Plan (HMBP) to the Fire Prevention Division. A completed plan must be submitted to this office within 30 days of commencing operations, undertaking change in ownership/operator, or carrying out process modification.

HMBP Requirements


  • Each of the HMBP elements needing to be completed by the facility and can be accessed and downloaded directly through Unidocs Quicklinks (Item Number: UN-020UPCF).
  • Businesses mandated to complete a HMBP are also obliged to provide on site personnel with annual, process-specific safety training. This action is to address the proper handling and transfer of the regulated materials, as well as response procedures in the event of a fire, spill or explosion.
  • Forms for documenting individual safety training can be accessed and downloaded directly through Unidocs Miscellaneous (Item Number: UN-074).
