Concord Hazardous Materials Rules for Businesses

Public Safety California 4 Minutes Read · published February 21, 2026 Flag of California

Concord, California businesses that store, use or generate hazardous materials must follow local and county rules for safe handling, reporting and emergency planning. Many requirements are implemented through the Contra Costa County Hazardous Materials Program and the Concord Fire Department, including Hazardous Materials Business Plans (HMBP), monthly/annual inventory reporting, and release notifications to regulators and the public. For most facilities the Certified Unified Program Agency (CUPA) process and the statewide CERS portal are used to submit plans and maintain records.Contra Costa County Hazardous Materials Program[1] CERS statewide portal[2] Concord Fire Department[3]

Start compliance by confirming whether your business is covered and which program (city or county) inspects you.

Covered activities typically include storing regulated quantities of flammable, toxic, corrosive or reactive substances and generating hazardous waste. The CUPA enforces requirements set out under California Health and Safety Code (state law) by reviewing HMBPs, conducting inspections, and issuing corrective actions.
