About each permit
Hazardous Materials / CUPA Permit
An auto repair shop that generates hazardous waste or a restaurant with a carbon dioxide beverage system of 1,000 SCF or more falls under the Certified Unified Program run by Permit Sonoma's Hazardous Materials Unit. A small quantity generator pays $233 (under 325 gallons a year) or $321 (325 gallons to under 5 tons), a large quantity generator of 5 to under 25 tons pays $841, the restaurant carbon dioxide plan is $530, and a Tier 1 aboveground petroleum storage facility pays $386, plus a 1.3% Technology Fee, as published on the FY 2026-27 schedule. These figures exclude the state surcharge, which County Code §29-8(b) includes in the application and annual fee. Permit Sonoma's CUPA page names three other CUPA agencies in the county: the Santa Rosa Fire Department, the Petaluma Fire Department, and the Healdsburg Fire Department, which regulates facilities in Healdsburg and Sebastopol; a business in those cities deals with that agency instead.
