 Aboveground Petroleum Storage Tanks

As of January 1, 2008, the Certified Unified Program Agencies (CUPAs) 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)).

APSA was enacted to protect the state's people and natural resources from aboveground petroleum storage tank spills. Facilities storing petroleum in aboveground tanks or containers with a shell capacity of 55 gallons or greater and a total storage capacity of 1,320 gallons or more are subject to APSA.  Facilities with one or more tanks in underground areas are also subject to APSA, regardless of the 1,320-gallon total petroleum storage capacity threshold.  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. Examples of petroleum includes crude oil, sludge, mineral oil, petroleum solvents, gasoline, diesel, jet fuels, residual fuel oils, lubricants, kerosene, soluble cutting and metalworking fluid containing petroleum, inks and coatings containing petroleum, biodiesel (if it's not 100% biodiesel), and used oils. LPG is not included. For more information on the APSA program, please see the Office of the State Fire Marshal's APSA webpage.

In addition, facilities with certain quantities of oil storage 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. More information on the SPCC program can be found on the EPA's Oil Spills Prevention and Preparedness webpage:
