Hazardous Materials Disclosure & Business Emergency Plan

About the HMBP Program

The Hazardous Materials Business Plan (HMBP) program was established in 1986. Similar in scope to the Federal Community Right-to-Know Act (EPCRA), the HMBP program provides information regarding hazardous substances at business facilities to local agencies, emergency responders, and the general public. The objective of this program is to prevent or minimize the damage to public health and safety and the environment from a release or threatened release of hazardous materials.

Who is Subjected?

Businesses in the state of California that use, handle, or store hazardous materials – including hazardous wastes – or extremely hazardous substances (EHS) in reportable quantities are required to submit an HMBP through the state database, the California Environmental Reporting System (CERS). Reportable quantities are defined as follows:

  • 55 gallons of a liquid, or
  • 500 pounds of a solid, or
  • 200 cubic feet of flammable compressed gas; 1,000 cubic feet of non-flammable gas, or
  • Extremely hazardous substances above the Threshold Planning Quantity (TPQ) 

Program Requirements

  • Electronically submit an HMBP via the California Environmental Reporting System (CERS) every year. Submittals must be made between January 1st through March 1st to meet this requirement.
  • Update HMBP within 30 days of any changes in the business, including but not limited to:
    • Change in quantity of previously disclosed hazardous material
    • Handling of a previously undisclosed hazardous materials at or above reportable quantities
    • Change of business address, business ownership, or business name
  • Grant permission and access to local regulatory agencies for mandated inspections

Frequently Asked Questions

Any material, because of its quantity, concentration, physical or chemical characteristics, poses a significant present or potential hazard to human health and safety or the environment if released into the workplace or the environment; or any material that is required to have a Material Safety Data Sheet according to Title 8, Section 339 of the California Code of Regulations.

If you use, handle or store hazardous materials in quantities equal to or greater than the following threshold quantities: 

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

AND / OR: 

Extremely Hazardous Substances (EHS) – Federal and State laws now mandate special reporting of chemicals found on the EHS list maintained by the US EPA. You must report any of these chemicals if the amounts on hand at any given time exceed the “Threshold Planning Quantity” (TPQ) on the list, or if they exceed the general quantities listed above (55 gallons/500 pounds/200 cubic feet), whichever is less. 

EXAMPLE: Chlorine gas is on the EHS list, with a TPQ of 100 pounds. You have up to 150 pounds stored on-site at any given time (a standard chlorine cylinder is 150 pounds). Even though you handle less than the 500-pound general quantity, you must still disclose because chlorine gas is a listed chemical. 

The EHS list can be found on the web at the EPA.
