Hazardous Materials Business Plan Program
The Hazardous Materials Business Plan (HMBP) program 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
Who is Required to Submit a HMBP?
HMBPs must be prepared by any business that handles a hazardous material, a mixture containing a hazardous material (including hazardous waste), or an extremely hazardous substance (as defined in Section 355.61 of Title 40 of the Code of Federal Regulations) at reportable quantities. The general reportable quantities of hazardous materials are equal to or greater than 55 gallons of a liquid, 200 cubic feet of a gas, and 500 pounds of a solid. Certain hazardous materials are exempt from these requirements (refer to California Health and Safety Code section 25507 for more information).
