Hazardous Materials Business Plan
The Hazardous Materials Business Plan program was established in 1986 and is similar in scope to the Federal Community Right-to-Know Act (EPCRA).
Hazardous Materials Business Plan (HMBP)
Helping businesses, emergency responders, and local agencies protect public health, safety, and the environment through hazardous materials reporting and preparedness.
Program Purpose
The Hazardous Materials Business Plan program provides key information about the hazardous substances that businesses store, use, or handle.
Public Safety
Local agencies, emergency responders, and the public use this information to prepare for and respond to releases or threatened releases of hazardous materials.
Program Overview
The program aims to reduce risks to public health, safety, and the environment.
California businesses must submit a Hazardous Materials Business Plan through the California Environmental Reporting System (CERS) if they use, store, or handle hazardous materials, hazardous waste, or extremely hazardous substances at or above applicable reporting thresholds.
Reporting Thresholds
- 55 gallons of liquid
- 500 pounds of solid material
- 200 cubic feet of flammable compressed gas
- 1,000 cubic feet of non-flammable compressed gas
- Any Extremely Hazardous Substance (EHS) at or above its Threshold Planning Quantity (TPQ)
Annual Submittal and Updates
Businesses covered by the HMBP program must submit their Hazardous Materials Business Plan electronically in CERS each year by March 1.
Businesses must also update the plan within 30 days of any significant change. Examples include changes in the quantity of previously reported hazardous materials, the addition of new hazardous materials at or above reporting thresholds, or changes to the business address, ownership, or business name.
