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 the Hazardous Waste, Underground Storage Tank, Aboveground Petroleum Storage Tank, and CalARP programs while the Fire Agencies administer the other two elements listed above.

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.
