Hazardous Materials Business Plans
Other programs the division implements include the Hazardous Materials Business Plan (HMBP) and investigating environmental crimes in conjunction with the Riverside County District Attorney's Environmental Crimes Task Force and the APSA (Aboveground Petroleum Storage Act) program.
Business Plans
Federal, State and local laws require that a Hazardous Material Business Plan be submitted by any business that uses, stores, and/or handles a hazardous material or a mixture containing a hazardous material in reportable quantities. The Fire Department shall be responsible for implementing and enforcing two of the six Unified Programs set forth in Chapter 9.48 of the Riverside Municipal Code. The elements of the Unified Programs consist of:
- Hazardous Materials Release Response Plans and Inventories (Hazardous Materials Business Plan)
- Aboveground Petroleum Storage Act (APSA)
- California Fire Code
As a result of Assembly Bill 2286, effective January 1, 2013, the California Environmental Reporting System (CERS) is the only approved method for filing Hazardous Materials Business Plans. The City of Riverside Fire Prevention Division implements the Hazardous Materials Business Plan program within the city limits. Businesses are required to submit their plan electronically annually. Maintaining accurate inventories, site maps and prevention plans will allow emergency responders the ability to pre-plan responses based on hazards specific to the business. The City of Riverside is a Participating Agency (PA) to the Riverside County Department of Environmental Health Certified Unified Program Agency (CUPA).
Business plans must be reviewed and submitted annually. The annual due date for these reviews is based on the expiration date of the annual permit issued by the County of Riverside Department of Environmental Health.
Chemical Inventory Thresholds
A Hazardous Materials Handler is identified as any facility storing hazardous materials and/or wastes in quantities greater than or equal to:
- 55 gallons of a liquid substance
- 500 pounds of a solid substance
- 200 cubic feet of compressed gas

Please note that for acutely or extremely hazards materials, these amounts are less.
Reporting a Hazardous Materials Release
Any threatened release of significant release of a hazardous material must be reported. A threatened release is a condition creating a substantial probability of harm to the extent where it is reasonably necessary to take immediate action to prevent, reduce, or mitigate damages to persons, property, or the environment. A significant release is subjective and may depend on a variety of factors such as the amount, the hazardousness of the material or waste, and the proximity of sensitive receptors such as schools, drains, and waterways, among other factors.
A release of a reportable quantity (RQ) of a hazardous material must also be reported. RQs are listed in the CERCLA lists . Another way to determine if a RQ has been exceeded is to use the Department of Energy’s online RQ calculator .

Closure Reports
Any person or business which has previously been required to submit a HMBP shall submit a closure work plan to the City of Riverside Fire Department at least 30 days prior to the closure, relocation, sale or exchange of the business and/or the real property on which the business is located. This report will describe the work to be performed to properly clean, inspect, sample and close the facility. The closure report shall be approved by the City of Riverside before the removal of hazardous or potentially hazardous materials or hazardous wastes from property prior to implementation.
If underground storage tanks are also being closed, a separate tank closure permit must be obtained from the County of Riverside Department of Environmental Health and the City of Riverside Fire Department and must be referenced in the overall closure plan.
No person shall operate or maintain a business where hazardous materials are handled without a valid permit issued by the County of Riverside Department of Environmental Health. Permits are issued to facilities who have paid all assessed fees and are in full compliance with no outstanding violations, including the annual HMBP update. If payment of fees is not received, a late penalty of 20% will be assessed after 60 days and an additional 80% after 90 days in accordance with our fee resolution.

Hazardous Materials Business Plan
CalEPA oversees the statewide implementation of the Hazardous Materials Business Plan (HMBP) program, which aims to prevent or minimize harm to public health and safety and the environment from a release or threatened release of a hazardous material.
Hazardous Materials Business Plan Program Overview
The Hazardous Materials Business Plan (HMBP) aims to prevent or minimize harm to public health and safety and the environment from a release or threatened release of a hazardous material. This is accomplished by providing emergency responders with the necessary information to effectively protect the public.
The California Environmental Protection Agency (CalEPA) oversees the implementation of the HMBP program at the state level. Certified Unified Program Agencies (CUPAs), and Participating Agencies (PAs), implement the program at the local level and are responsible for enforcement and administration in their respective jurisdictions.
What is a Hazardous Materials Business Plan?
A HMBP contains detailed information that includes the following:
- An inventory of hazardous materials at a facility.
- Emergency response plans and procedures to be followed in the event of a reportable release or threatened release of a hazardous material.
- Requirements to train employees in safety procedures in the event of a release or threatened release of a hazardous material, including onboarding for new employees and annual refresher courses for existing employees.
- A site map that depicts north orientation, loading areas, internal roads, adjacent streets, storm and sewer drains, access and exit points, emergency shutoffs, evacuation staging areas, hazardous material handling and storage areas, and emergency response equipment.
For more information, see the HMBP Resources page .
HMBP Annual Certification
As of September 18, 2020, business owners/operators may easily certify HMBP information in the California Environmental Reporting System (CERS) as complete, accurate and, if applicable, meeting EPCRA reporting requirements.
