COVID-19 Information and Guidance
The Environmental Management Department's Hazardous Materials Business Plan (HMP) Program is one program element within the Sacramento County
Certified Unified Program Agency (CUPA). The HMP Program is administered throughout the County of Sacramento and its incorporated cities.
The purpose of the HMP Program is to protect public health and the environment and groundwater from risks or adverse effects associated with the storage of hazardous materials. Businesses must complete a Hazardous Materials Business Plan (Business Plan) for the safe storage and use of chemicals.
In general, you must submit a Business Plan if your business handles and/or stores a hazardous material equal to or greater than the minimum reportable quantities. These quantities are 55 gallons for liquids, 500 pounds for solids and 200 cubic feet (at standard temperature and pressure) for compressed gases.
Hazardous Materials Business Plans are submitted electronically. Visit the
Electronic Reporting information page for the latest information!
