Overview of Requirements

Local rules for hazardous materials storage and spill response in Orange are implemented through municipal code provisions, fire prevention programs and the Certified Unified Program Agency (CUPA) process for hazardous materials business plans and inventories. Businesses should maintain a current hazardous materials inventory, secondary containment where required, compatible storage, and written spill response procedures.

Key local participants include the City of Orange departments responsible for code enforcement and planning, and the regional hazardous materials authority that administers CUPA duties. For the controlling municipal code and administrative rules, consult the city code and the local hazardous materials program pages City of Orange Municipal Code[1], the regional fire authority hazardous materials program Orange County Fire Authority Hazardous Materials[2], and the City code enforcement and business permit pages City of Orange Code Enforcement[3].

  • Maintain a hazardous materials inventory and Safety Data Sheets (SDS) onsite.
  • Use approved containers and secondary containment for liquids and corrosives.

  • Post emergency contact and evacuation information near storage areas.
Documentation is the first thing inspectors will request during an inspection.
