CUPA Aboveground Petroleum Storage Tank

Effective January 1st, 2008, Assembly Bill 1130 (AB1130) authorized the administration and implementation of the Aboveground Petroleum Storage Tank (APST) Program to the local Certified Unified Program Agency (CUPA). For businesses in Orange County, the State Water Resources Control Board (SWRCB) will no longer be the regulating agency for APST’s. Instead, the APST Program has been delegated to the Orange County CUPA throughout the County. This change is positive for both businesses and OC CUPA as it consolidates environmental programs, fees, and inspection authority into one single regulating agency- thus, creating essentially a “One-Stop Shop."

The Aboveground Petroleum Storage Act of 1990 (APSA) requires owners or operations of aboveground petroleum storage tank (APST) facilities to file a tank facility statement, to develop and implement a Spill Prevention Control and Countermeasure (SPCC) Plan, and to pay fees. The purpose of this program is to protect the state’s people and natural resources from aboveground petroleum storage tank spills or releases.
