APSA

California Aboveground Petroleum Storage Act 

The Aboveground Petroleum Storage Act (APSA) applies to owners and operators with a total storage capacity of 1,320 gallons* or more of petroleum at a facility. Petroleum stored in aboveground tanks, containers, and equipment 55-gallons or greater is subject to this law. The Department of Environmental Health (DEH)Hazardous Materials Division (HMD) is the Certified Unified Program Agency (CUPA) responsible for the regulatory inspections of all Tank Facilities subject to APSA in the County of San Diego.  The main purpose of the APSA inspection program is to verify tank facilities have prepared and are implementing a Federal Spill Prevention, Control, and Countermeasure (SPCC) Plan. 

In APSA, the term “petroleum” means crude oil, or a fraction thereof, that is liquid at 60 degrees Fahrenheit temperature and 14.7 pounds per square inch absolute pressure. Please refer to the state law for additional information.

*Some facilities with less than 1,320 gallons of petroleum with a tank in an underground area would be subject to APSA.  Please refer to the Guide to Understanding Tanks in Underground Areas in the APSA Program for more information.

 Aboveground storage capacity more than 10,000 gallons:

Large Tank Facilities, with a storage capacity of more than 10,000 gallons of oil must use a Professional Engineer to certify the SPCC Plan. The USEPA provides resources and guidance on their website.

 
 Aboveground storage capacity of 10,000 gallons or less:
Tank Facilities with a total storage capacity of  ≥1,320 gallons and ≤10,000 gallons of oil, with limited or no oil releases, are considered "Qualified Facilities" under the federal SPCC rule. There are two types of qualified facilities, Tier I and Tier II. Qualified Facilities may use ready-made templates to develop their SPCC Plan and may self-certify their SPCC Plan. To assist owners and operators, HMD developed an online course: How to Prepare Your Own SPCC Plan :  A Step by Step Guide for Tier I Qualified Facilities Using the U.S. EPA SPCC Template
 
Tier I facilities may prepare and self-certify their own SPCC plan. U.S. EPA SPCC Plan Template - Tier I Qualified Facilities
 
Tier II facilities may also prepare and self-certify their own SPCC plan.  SPCC Plan Template - Tier II Qualified Facilities
