Aboveground Petroleum Storage Tanks

The Aboveground Petroleum Storage Act (Health & Safety Code Chapter 6.67) covers all non-exempt facilities storing petroleum. A tank facility is regulated under APSA if:

  • Tank facility has a storage capacity of 1,320 gallons or more of petroleum.
  • Tank facility has one or more tanks meeting the definition of a "tank in an underground area."
  • Tank facility is subject to the federal SPCC rule specified in the Code of Federal Regulations, Title 40, Part 112.

Covered businesses are required to file a storage statement with the Certified Unified Program Agency (Environmental Health) and, with certain exceptions, prepare and implement a Spill Prevention Control and Countermeasure (SPCC) plan in accordance with federal law. The object of the SPCC plan is to prevent discharges of petroleum from causing water pollution.

Tier I Facilities

Facilities must meet the following criteria to be considered APSA Tier I facilities:

  • Must have capacity to store no more than 10,000 gallons of oil.
  • Must have no single container with a capacity larger than 5,000 gallons.
  • Must have no single discharge to navigable waters or adjacent shorelines exceeding 1,000 gallons and no two discharges, each exceeding 42 gallons within any 12-month period in the past three years.

Tier I facilities may use the EPA-designed template and may self-certify their Plan.

Tier II Facilities

Facilities must meet the following criteria to be considered APSA Tier II facilities:
  • Must have capacity to store no more than 10,000 gallons of oil.
  • Must have a single tank or container with a capacity to store greater than 5,000 gallons.
  • Must have no single discharge to navigable waters or adjacent shorelines exceeding 1,000 gallons and no two discharges, each exceeding 42 gallons within any 12-month period in the past three years.

Tier II facilities may use the CalCUPA Forum Board designed template and may self-certify their Plan.

Full-Plan Facilities

Facilities that have the capacity to store more than 10,000 gallons of petroleum-based products above ground are considered to be full-plan facilities. These facilities must develop a full SPCC Plan. The Plan must be certified and stamped by a Professional Engineer and be approved by the facility or corporation management.
