Hazardous Materials Business Plan
The Hazardous Materials Business Plan (HMBP) is detailed information on the storage and use of hazardous materials at a regulated business facility. The main objective of having an HMBP is to provide site-specific information for emergency responders to help them better prepare and respond to chemical-related incidents at the facility and to minimize damage to public health, safety, and the environment from released or potentially released hazardous material.
Basic Need-to-Know Responsibilities
Any facility that handles hazardous materials, waste, or extremely hazardous substances at reportable quantities is required by law to provide their HMBP through the CERS program. Reportable quantities are as follows:
- 500 lbs of solid hazardous waste material
- 55 gal of liquid hazardous material
- 200 cu ft of compressed gas
Any facility with the above quantities of hazardous materials must maintain an active permit through Environmental Health by paying annual fees.
California Environmental Reporting System (CERS)
All businesses handling hazardous materials are required to make annual electronic submittals through CERS to report facility information, hazardous materials inventory, site maps, and emergency response and training plans. Additional information is required if the business participates in additional CUPA programs such as:
- Underground Storage Tanks (UST)
- Aboveground Petroleum Storage Tank (AST/APSA)
- Hazardous Waste Generator (HWG)
- Remote Waste Consolidation

As of January 1, 2019, Annual CERS submittals are due by March 1st of each year. HSC 25508(a)(2)
To ensure that HMBP requirements are met and that the facility complies with State and Federal law, the Environmental Health Department conducts routine inspections at all facilities required to submit an HMBP. These inspections also assist in identifying safety hazards that could lead to an accidental spill or release of hazardous materials and allow the Specialist to work with facility owners on how to avoid hazardous release problems.
HMBP Exemption for Low-Risk Facilities
Low-risk facilities storing limited volumes of hazardous materials in areas away from neighbors or the public may
be eligible for exemption from this program. Download the application (PDF) for specific exemption requirements.
