Hazardous Materials Business Plan
The goal of the Hazardous Materials Business Plan (HMBP) program is to protect both human and environmental health from adverse effects as a result of the storage or possible release of those materials. This is done primarily by documenting significant amounts of hazardous materials so that emergency responders can effectively protect the public. HMBPs also satisfy Community Right-to-Know laws for public accessibility.
California Health and Safety Code, Division 20, Chapter 6.95, §25500-25519
California Code of Regulations, Title 19, Division 2, Chapter 4
Storage of any hazardous materials at or above State-defined thresholds makes a facility subject to the HMBP program. The general thresholds are 55 gallons of a liquid, 200 cubic feet of a gas, and 500 pounds of a solid. There are some exemptions to these thresholds.
The Hazardous Materials Compliance Division (HMCD) is responsible for the HMBP program within the cities of Los Altos, Los Altos Hills, Milpitas, Monte Sereno, Morgan Hill, San Jose, and Saratoga, as well as unincorporated areas of the County (including Moffett Field, San Martin, and Stanford). If your facility is located in a different city within the County, please refer to the Who Regulates What table.
