New for 2018: Federal Hazard Categories

Effective December 28, 2017, CalEPA will be replacing the existing five (5) federal hazard categories available in CERS used for the completion of chemical inventories as part of the annual hazardous materials business plan submittal with twenty-four (24) new federal hazard categories adopted by the United States Environmental Protection Agency (U.S. EPA) as a result of changes to the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS).  For more information, please see the CERS Business Guidance Document.

About Us

The Environmental Health Division was designated as the Certified Unified Program Agency (CUPA) for the County of Orange by the State Secretary for Environmental Protection on January 1, 1997. The CUPA is the local administrative agency that coordinates the regulation of hazardous materials and hazardous wastes in Orange County through the following six programs:

County and City Fire Agencies within Orange County have joined in partnership with the CUPA as Participating Agencies (PAs). In most Orange County cities, the Environmental Health Division administers all programs, with the exception of La Habra, Fullerton, Costa Mesa, Huntington Beach, Newport Beach, Orange and Fountain Valley in which case the local Fire Agencies are responsible for the Hazardous Materials and Business Emergency Plan Programs. The Fire Agencies in the cities of Orange and Fullerton also administer the Underground Storage Tank Program and LA County Fire administers the CalARP and HMD/BEP programs for the City of La Habra.

The CUPA provides its regulated businesses several convenient benefits such as a single point of contact for permitting, billing and inspections; uniformity and consistency in enforcement of regulations; and a single fee system incorporating all of the applicable fees from the six CUPA programs. For more information, please call 714-433-6000.
