Aboveground Petroleum Storage Act
(APSA) Program Fees [PDF]
On September 27 & 30, 2011, Stanislaus County CUPA will host an APSA informational workshops for businesses. This workshops will present information and guidance to assist in preparing or updating an SPCC Plan or Plan Template, and how to be in compliance with APSA and SPCC regulations. The handouts to be given during the workshops can be accessed through the following links:
Regulations for Aboveground Petroleum
Storage Tank Facilities
The State Water Resources Control Board, with EPA concurrence, has
determined that ANY aboveground petroleum storage tank in California has a
reasonable possibility of discharging oil in harmful quantities into or upon
the navigable waters of the United States or adjoining shorelines are
subject to the Act.
As the Certified Unified Program Agency (CUPA) for Stanislaus County, the
Hazardous Materials Division is authorized to ensure that businesses which
are impacted by the State of California Aboveground Petroleum Storage Act
(APSA) have a Spill Prevention Control and Countermeasure (SPCC) Plan in
place. Below are guidelines for complying with APSA. The regulations
contained in the APSA are in conformance with the Federal regulations
promulgated by the Environmental Protection Agency (EPA) under the authority
of the Federal Water Pollution Control Act (FWPCA) as defined in Title 40,
Code of Federal Regulations, Part 112 (40 CFR, Part 112). Under the FWPCA,
Federal agencies are also required to comply with State and local
regulations with respect to oil pollution prevention.
If your facilities has an aboveground petroleum storage tank with a single
tank capacity greater than 1,320 gallons or with a cumulative storage
capacity of 1,320 gallons stored in containers of 55 gallons or greater, you
are required to develop and implement an SPCC Plan.
The California APSA only regulates tank facilities that store petroleum and
not other oils, as does the federal SPCC Rule. Businesses that are required
to have SPCC plans but do not store petroleum are not within our
jurisdiction and are not included in this program.
Petroleum is defined in the APSA as "crude oil, or any fraction thereof,
which is liquid at 60o F and 14.7 lbs/in2 absolute pressure (normal
atmospheric pressure). Fuels that are not liquid at 60o F are not
considered "petroleum" under the APSA definition. Additionally 100%
vegetable or plant based oils are NOT regulated under APSA unless the fuel
contains 1% or greater concentration of petroleum.
A "Qualified Facility" Tier 1 and Tier 2 template SPCC Plan is Available for tank facilities to complete, self-certify, and implement in lieu of a full PE certified Plan. To use the Federal "Qualified Facility" Exemption you must meet all of the following:
- 10,000 gallons or less of total aboveground oil storage capacity(Qualified Facilities must use the federal definition of oil, which means oil of any kind or in any form including petroleum; fuel oil; sludge; oil refuse; oil mixed with wastes other than dredged spoil; fats, oils or greases of animal, fish, or marine mammal origin; vegetable oils, including oil from seeds, nuts, etc).
- Has not within any 12 month period in the three years prior to
creating the SPCC had:
a.) single discharge of 1,000 gallons or more to navigable waters or,
b.) two discharges to navigable water each exceeding 42 gallons.
- A Tier 1 Qualified Facility does not have an AST greater than 5,000 gallons, a Tier 2 Qualified Facility has an AST greater than 5,000 gallons.
- If your facility has an AST greater than 5,000 gallons but
your total oil storage capacity is less than 10,000 gallons you may still
self-certify and implement the SPCC plan in lieu of a full PE certified Plan,
but may not use the template plan found in appendix G to 40 CFR 112.

- Tier 1 Qual Facility SPCC Plan Template
The USEPA plan Tier 1 Qual Facility SPCC
Plan Template above contains incorrect information. The USEPA has
acknowledged this but has not yet published a revised version. This does
not relieve you from completing and implementing an SPCC plan, but be aware
that if you download and complete this form you may have to redo your plan
at a future date
- Tier 2 Qual Facility SPCC Plan Template [PDF]
This Tier II SPCC Plan template has been developed by the CalCUPA Forum Board's APSA Working Group and is intended to serve as an SPCC Plan template for use by Tier II Qualified Facilities meeting 40 CFR §112.3(g)(2). Although the 40 CFR 112 SPCC rules do not specifically provide for, nor has US EPA developed, a plan template for use by Tier II Qualified Facilities, this Tier II plan template to the best of our knowledge would allow a Tier II Qualified Facility properly completing the template to meet the requirements for preparation of a written SPCC Plan as specified for Tier II Qualified Facilities. This template has not been reviewed or approved by the US EPA.
Conditional California APSA Exemptions exempt some facilities from preparing an SPCC plan. This conditional exemption applies to a farm, a nursery, Logging site and a construction site*, if (1) no aboveground tank exceeds 20,00 gallons and (2) the cumulative storage capacity at the site is less than 100,000 gallons. To maintain this exemption the facility must conduct daily inspections of the aboveground tank(s), be inspected by the local CUPA and install secondary containment if required. These facilities may still be required to prepare and implement a Federal SPCC plan.
*A construction site is the portion of the facility that is actually undergoing construction. A construction yard is not a construction site.

(UFC Secs. 7901.3, 105.8.f.3.2, and 105.8.f.3.3). UFC Sec. 5202.4.1, App. II-F, Sec. 3, describes the permit and plans application requirements and the information that must be submitted with the application.
Before purchasing, installing, or retrofitting an existing tank the local Fire Marshall and the California Air Resources Board should be contacted for any site specific restrictions. In some locations you may be able to obtain a written waiver of certain UFC requirements.
There are several commercial tank systems available that meet the requirements of the ACT, and the OSHA and UFC regulations. Many of these tanks are also available with optional equipment to meet any California Air Resources Board requirements for vapor recovery . Serious consideration should be given to purchasing one of these self contained units when constructing a new tank facility or to bring an existing tank facility into compliance. Many of these tanks are on the GSA schedule.
When AST's are abandoned, temporarily taken out-of-service, or removed the applicable Federal, State, and local regulations must also be followed. UFC regulations require all AST's not used for a period of 90 days to have all liquids removed from the tank, all piping capped or plugged and secured against tampering, and the vent lines open and properly maintained. AST's that are out of service for one year or more must be removed from the property.
AGT Monitoring Program
H&SC section 25270.7 - The owner or operator of a tank facility shall establish and maintain a monitoring program pursuant to subdivision (1) or (2), as applicable, which shall be approved by the regional board, to detect releases to the soil and water, including both groundwater and surface water. The owner or operator shall establish the required monitoring program in accordance with the requirements and a schedule prescribed by the regional board. The owner or operator subject to this section shall designate a schedule for monitoring and the sample locations, which shall be approved by the regional board. The owner or operator shall make the monitoring results available to the regional board & the Dept. of Fish and Game.
|( 1 )
|| Each owner or operator of a tank facility subject to this chapter which, because of the tank location, tank size, characteristics of the petroleum being stored or the spill containment system, has the potential to impact surface waters or sensitive ecosystems, as determined by the regional board, shall do either of the following:
|| Install and maintain a system, approved by the regional board, to detect releases into surface waters or sensitive ecosystems.
|| If any discharge from a tank facility flows, or would reasonably be expected to flow, to surface waters or a sensitive ecosystem, allow a drainage valve to be opened and remain open only during the presence of an individual who visually observes the discharge.
|( 2 )
|| Each owner or operator of a tank facility subject to this chapter which, because of the tank facility location, tank size, or characteristics of the petroleum being stored (16 degrees API or lighter), has the potential to impact the beneficial uses of the groundwater, as determined by the regional board, and which is not required to have a groundwater monitoring program at the tank facility pursuant to any other federal, state, or local law, shall do any of the following:
|| Install a tank facility groundwater monitoring system which will detect releases of petroleum into the groundwater, as approved by the regional board.
|| Install and maintain a tank foundation design which will provide for early detection of releases of petroleum before reaching the groundwater, as approved by the regional board.
|| Implement a tank water bottom monitoring system and maintain a schedule which includes a log or other record which will identify or indicate releases of petroleum before reaching the groundwater, as approved by the regional board.
|| Use other methods which will detect releases of petroleum into or before reaching the groundwater, as approved by the regional board.
|( 3 )
