Hazardous Materials Unit

CUPA Programs

The Hazardous Materials (HazMat) Unit has the responsibility for the County's Certified Unified Program Agency (CUPA) Programs.

Portions of the California Fire Code which address hazardous materials are also enforced by this Division. Inspections of businesses in the County which are included in any of these programs are conducted on a routine basis, and our Division often works in conjunction with the County’s Environmental Health Department as well as local fire departments. Funding for this Division is provided through fees charged to the businesses which are regulated by the County under these CUPA programs. There are approximately 1400 businesses covered by one or more of the CUPA programs. Information regarding hazardous materials in your community can be obtained from this Division.

There are three other CUPA agencies in Sonoma County which regulate facilities in their communities: Santa Rosa Fire Department, Petaluma Fire Department and Healdsburg Fire Department, which regulates facilities within Sebastopol and Healdsburg through a Joint Powers Agreement. If you have questions regarding facilities within any of those cities, contact the appropriate fire department.

California Public Records Act (PRA)

An important responsibility our Unit has as the CUPA is sharing responsibility with the public on facilities within their community that handle hazardous materials under the California Public Records Act (CA Code 6250-6270). To submit a request for such information, visit Section 1-0-5 of our Policies and Procedures. Important: A site address or address range will need to be identified to obtain this information.
