Welcome to the

Hazardous Materials Division and Certified Unified Program Agency (CUPA)

CUPA Programs

The Hazardous Materials (HazMat) Division has the responsibility for the County's Certified Unified Program Agency (CUPA) Programs. These programs include:

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, Permit and Resource Management Department (PRMD), 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.

Emergency Response

The HazMat Division is also responsible for emergency response to hazardous materials incidents throughout most of the County in coordination with local response personnel. The Hazardous Materials Response Team is part of this Division and consists of volunteer community members as well as Department staff who are trained to respond to any level of hazardous material incident in the county.

California Public Records Act (PRA)

An important responsibility our Division 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).
