| Aboveground Petroleum Storage Tanks
As of January 1, 2008, the Certified Unified Program Agencies (CUPA) have the responsibility and authority to implement and enforce the requirements of Chapter 6.67 of the California Health and Safety Code (the Aboveground Petroleum Storage Act (APSA)).
The APSA was enacted to protect the state's people and natural resources from aboveground petroleum storage tank spills. Facilities storing petroleum in aboveground tanks with a capacity greater than 1,320 gallons or the total capacity for the facility greater than 1,320 gallons are subject to the Act. Petroleum means any crude oil, or fraction thereof, which is liquid at 60 degrees Fahrenheit temperature and 14.7 pounds per square inch absolute pressure. This includes petroleum based substances comprised of a complex blend of hydrocarbons, such as gasoline, diesel, jet fuels, residual fuel oils, lubricants, some petroleum solvents and used oils. LPG would not be included.
Owners or operators of aboveground tanks subject to the Act are required to prepare and implement a Spill Prevention Control and Countermeasure (SPCC) Plan in accordance with U.S. Code of Federal Regulations, Title 40, Part 112 and conduct periodic inspections to assure compliance with 40CFR112. For more information about SPCC plans, see the CalEPA Fact Sheet on Spill Prevention Control and Countermeasure Plan Requirements.
