Aboveground Petroleum Storage Tank Program

Environmental Health Services

Storing petroleum in aboveground storage tanks benefits businesses and the community. However, there are also risks in storing petroleum in aboveground storage tanks.

Aboveground storage tanks can leak and pose a threat to the navigable waterways of San Mateo County.

In order to protect the public health, the navigable waters and the San Mateo County ecosystem, federal and state regulations exist to inspect the operations of aboveground storage tanks. Assembly Bill 1130 (Laird), Aboveground Petroleum Storage Act (APSA), became effective on January 1, 2008. The law transfers the responsibility for the implementation, inspection, enforcement and administration from the State to the Certified Unified Program Agency (CUPA).

In addition, the law requires facilities with certain quantities of oil storage to prepare a Spill Prevention Control and Countermeasure (SPCC) plan in accordance with federal requirements.

The Health and Safety Code defines an “Aboveground Storage Tank” or “Storage Tank” as a tank that has the capacity to store 55 gallons or more of petroleum and is substantially or totally above the surface of the ground. Additionally, a “Tank Facility” means one or more aboveground storage tanks, including any piping that is integral to the tanks, that contain petroleum and are used by a single business entity at a single location or site.

A Tank Facility that stores 1,320 gallons or more of petroleum in aboveground storage containers or tanks is required to comply with APSA, prepare and implement a Spill Prevention Control and Countermeasure (SPCC) plan, and submit an annual Aboveground Petroleum Storage Tank Facility Statement.

For more details or if you have questions regarding your facility, contact your local inspector at 650-372-6200.

FAQs

If you have a petroleum storage capacity of 10,000 gallons or less, and the largest container is 5,000 gallons or less, you can self-certify using the Template for Tier I facilities (EPA).  Be sure to complete all applicable sections. Alternatively, you can have a Professional Engineer-certified plan.

If you have a petroleum storage capacity of 10,000 gallons or less, and the largest container is greater than 5,000 gallons, you can self-certify using the Tier II Template from CAL-CUPA. Be sure to complete all applicable sections. Alternatively, you can have a Professional Engineer-certified plan.

If you have a petroleum storage capacity greater than 10,000 gallons, you must have a Professional Engineer (PE) certify your plan. Contact your inspector if you need assistance finding a PE.

SPCC plans must be reviewed every five years or if there are significant changes to storage volume or containers/tanks.

The APSA Template for Tier I facilities provides information about minimum tank inspection requirements on page 17 and a sample log on page 16. This template can be used for any SPCC facility type. A more in-depth inspection checklist, SP001, is also available below.

Keep records of inspection for three years.

Training for newly hired oil-handling employees must cover:

  • Operation and maintenance of equipment to prevent discharges.
  • Discharge procedure protocols.
  • Applicable pollution control laws, rules and regulations.
  • General facility operations.
  • Annual Briefings to assure adequate understanding by including a review of past reportable discharges or failures, malfunctioning components and any recently developed precautionary measures.

The template also has a page to document this. Template for Tier I facilities, P.19, attachment 3.4.

If you prefer to combine this training with annual HMBP training, you can record it on the HMBP training log, but you must provide a description of the training topics covered on the form Training – Record for HMBP. Log this on the pages mentioned above if you use a Tier I or Tier II SPCC plan.

The template also has a page to document this. Template for Tier I facilities (EPA), P.13 & 14.  attachment.

The 5-year review log is used to document when the plan was reviewed (and amended if applicable). A review must be documented every five years, at a minimum.

The technical amendments log can and must be updated at any time to include amendments to the plan. The amendments must be added within six months of a change at the facility and must be implemented no later than six months from the amendment date.
