Hazardous Materials Business Plans
Hazardous Materials Business Plans (HMBP)

The Hazardous Materials Business Plan program was established in 1986 and is similar in scope to the Federal Community Right-to-Know Act (EPCRA). These laws were passed in response to the chemical disaster in Bhopal India in 1984 and to other incidents that had occurred in the United States. The goal is to prevent or minimize the damage to public health and safety and the environment, from a release or threatened release of hazardous materials. This is achieved by businesses providing their chemical inventories to local agencies that in turn provide that information to their emergency responders.

The Hazardous Materials Business Plan law improves the ability for local emergency response agencies and the public's knowledge and access to information on chemicals at individual facilities, their uses, and releases into the environment. States and communities, working with facilities, can use the information to improve chemical safety and protect public health and the environment.

Under this regulation, the approximately 140,000 businesses in California, both small and large, are required to plan for possible emergencies and report chemical information electronically to their local CUPA via the California Environmental Reporting System (CERS) or through a local CUPA’s online Portal.
