What is an HMBP?

A Hazardous Materials Business Plan (HMBP) is a package of information that your business is required to provide us if the amount of any hazardous material/waste at your facility meets or exceeds reportable quantities*:

  • 500 pounds of a solid
  • 55 gallons of a liquid
  • 200 cubic feet of a compressed gas 

*Additional qualifiers apply. See below. 

An HMBP will contain information related to: 

  • Facility information
  • Hazardous materials inventory
  • Site map
  • Emergency response plans and procedures
  • Employee training program

The purpose of the HMBP is to protect and minimize damage to public health, safety, and the environment from a release or threatened release of a hazardous material. Information from HMBPs is used to assist with emergency responses to a release or threatened release of a hazardous material within a city of a county.

For more information on HMBPs, please visit CalEPA's HMBP webpage and HMBP FAQ webpage.

Note: An "HMBP" can refer to both the regulatory program and the package of information submitted for the regulatory program.
