CHAPTER 3 

Underground Storage Tanks

This chapter summarizes:

 Regulations for underground fuel storage tanks

 Prevention of spills, overfills, and corrosion

 Leak detection options

3.1 Introduction

The Resource Conservation and Recovery Act (RCRA) mandates th

Environmental Protection Agency (EPA) to develop a program for underground storage tanks (USTs) storing petroleum products. Federal regula

were written to describe performance standards for USTs, how to prevent

contamination of soil and groundwater by leaking USTs (LUSTs), how to properl

close tanks, and what to do if a release occurs. You can find these regulations in 

Title 40 of the Code of Federal Regulations, Part 280 (40 CFR 280

On July 15, 2015,EPA published the first major revision to the federa

regulations since 1988. The revisions to the UST regulations removed deferral

for Airport Hydrant Systems, field constructed tanks, and emergency generato

tanks; additionally, the revisions modified other significant aspects to the 

regulations. See Section 3.8, For More Information for links to 40 CFR 280.

has provided a technical compendium at https://www.epa.gov/ust/underground-storage-tank-ust-technical-compendium-about-2015-ust-regulations

that covers EPA’s interpretation and guidance to the revised regulations. 

compendium addresses several topics, including field constructed tanks, spill 

bucket and dispenser inspections, and operator training. 

The requirements of 40 CFR 280 apply to USTs that contain regulated substances and petroleum that have 10% or more of their volume (including the volu

of connected underground pipes) below ground. PA defines regulat

substances as any Comprehensive Environmental Response, Compensation

and Liability Act (CERCLA) hazardous substances (except for hazardous was

and petroleum (including blends such as motor fuels, jet fuels, distillate fuel 

oils, lubricants, petroleum solvents, and used oils). The CERCLA list of hazard

substances can be found in 40 CFR 302.4

3.2 Requirements for USTs

USTs and their associated piping must comply with specific design, construction, installation, operating, and release detection requirements. For information on piping requirements, see Chapter 5, Piping and Pipelines

 All underground storage tanks 

(USTs) must have equipment 

for spill and overfill prevention, 

leak detection, and corrosion 

protection (40 CFR 280 Subpart C 

and D).

 Only trained personnel who 

follow standard procedures may 

install new tanks or close existing 

tanks (40 CFR 280.20(e)).

 You must comply with the 

Spill Prevention, Control, and 

Countermeasure (SPCC) Plan 

requirements if you have at least 

42,000 gallons of UST capacity, 

or have at least 1,320 gallons of 

aboveground storage tank oil 

capacity in 55-gallon or larger 

containers (40 CFR 112.1).

 2015 revised UST regulations: 

– Added secondary containment 

requirements

– Added operator training requirements

– Added operational inspection 

requirements

– Added requirements for biofuel 

compatibility

– Removes several deferrals

The Law Says
3-2 Chapter 3 Underground Storage Ta

3.2.1 Corrosion Protection

To help prevent corrosion, make sure you install only well-designed and well-constructed tanks. Unprotected steel corrodes and can release product (fuel) from

holes that begin as pitting on the metal surface. Unless non-corrosive soil conditions exist at your facility, you must protect from corrosion by doing at least one 

of the following:

 Use tanks of non-corrodible materials, such as fiberglass-reinforced plastic or 

a steel−fiberglass-reinforced plastic composite

 Protect steel tanks by coating them with a suitable non-conducting material,

and use a cathodic protection system (with impressed current or sacrificial 

anode, as described below)

 Get approval from your regulatory agency for another corrosion protection

method that is equally safe (new techniques are emerging)

An impressed current system uses a rectifier to convert alternating current to

direct current (see Exhibit 3−1). This current is sent through an insulated wire

to the anodes, which are special metal bars buried in the soil near the UST. Th

current then flows through the soil to the UST system and returns to the rectifier

through an insulated wire attached to the UST. The UST system is protect

because the current going to the UST system overcomes the corrosion-causing

current normally flowing away from it.

Another type of cathodic protection is called a sacrificial anode or galvanic

anode system (see Exhibit 3−2). The galvanic anode system relies on the natural

potential difference between the metallic sacrificial anode (usually aluminum, 

magnesium, or zinc) and the steel tank to provide a protective flow of current. 

Metal ions migrate from the more reactive metal anode to the tank and, in the 

process, the anodes corrode (are sacrificed).

Only a qualified cathodic protection expert can determine what kind of cathodic

protection will work at your UST site

3.2.2 Spill and Overfill Prevention Equipment

To prevent spills and accidental overfills associated with product transfers, you

must use spill prevention equipment, such as a spill catchment basin (see Exhibit 

3−3), and overfill prevention equipment, such as automatic shutoff devices, 

overfill alarms, and ball float valves (fitted to the vent pipe) (see Exhibit 3−4). 

Routine inspections and testing of spill prevention equipment is required. If

the spill prevention device is double walled, the interstice may be monitored 

during routine inspections in lieu of routine testing. Periodic inspection of overfill

prevention devices is required to be conducted in accordance with prescribed 

requirements. Alternative spill and overfill prevention equipment that is equally

safe may be used with regulatory agency approval.

3.2.3 Installation of USTs

All tanks and piping must be properly installed according to a nationally recognized code of practice and according to the manufacturer’s instructions. Use

a qualified installer; have the installation inspected by a licensed Professional

Engineer (PE) or the regulatory agency and certify the installation method us

on the appropriate agency notification form.

3.3 General UST Operating Requirements

New and upgraded USTs have a collection of mechanical and electronic device

that can fail under certain conditions. These failures can be prevented or quickly

detected by following general UST operating requirements. Having a new or upgraded UST system is a good start, but the system must be properly operated a

continuously maintained to ensure that leaks are avoided or quickly detected.

3.3.1 Spill and Overfill Control

To prevent spills and overfills, use correct filling practices when transferring

product. Make sure there is room in the tank before delivery, and watch the entire 

delivery. Report, investigate, and clean up any spills and overfills accordingly

3.3.2 Operator Training 

Owners and operators must implement a training program that identifies U

personnel as either Class A, Class B, or Class C operators. Each operator class mus

meet specified training requirements, pass evaluation, and maintain documentation of training completion. Operators must be trained as either Class A, Class B

or Class C operators. For more information on training requirements see Chapter 

10, Training.

The training program must ensure

 Class  operators have the knowledge and skills to make informed decisions

for UST compliance and the ability to determine if operating staff are

operating the system in compliance.

 Class B operators have the knowledge to implement UST compliance

requirements for the site-specific UST system components

 Class C operators have the knowledge to take actions in response to 

emergencies, alarms, or spills resulting from operating the UST system

3.3.3 Operation and Maintenance

Conduct all UST system repairs according to a nationally recognized code of

practice, and meet the following requirements:

 Ensure continuous operation of corrosion-protection systems for tanks that

routinely contain product.

 Have all cathodic protection systems tested by a qualified cathodic

protection tester within 6 months of installation and at least every 3 years 

thereafter.

 Inspect impressed current cathodic protection systems (the rectifier) every 60 

days to ensure that the equipment is working properly.

 Replace corroded or damaged metal fittings that have released product.

Fiberglass fittings may be repaired according to manufacturer’s specifications.

 Tightness-test repaired tanks and piping within 30 days of the repair.

 Test cathodic protected UST systems within 6 months of repai

EXHIBIT 3−4

Chapter 3 Underground Storage Tanks 

3.3.4 UST Leak Detection

All USTs systems must have a method of leak detection. Use one, or a combination, of the following monitoring methods at least every 30 day

 Vapor monitoring in soil

 Interstitial monitoring (detection of liquids in the space between a tank and 

its outer containment wall)

 Automatic tank gaugin

 Groundwater sampling from nearby monitor well

 Statistical inventory reconciling

 Other approved method

EPA allows facilities to use manual tank gauging as the sole method of leak detection for small USTs (under 550 gallons). Exhibit 3−5 shows typical leak detect

methods. Other methods can be used if they meet a performance standard of

detecting a leak of 0.2 gallons per hour with a probability of detection of at least 

95% and a probability of false alarm of no more than 5%. PA has develop

evaluation procedures for innovative leak detection systems to be reviewed by 

an independent third party. You should obtain a signed certification from the 

leak detection vendor that verifies the system meets the regulatory performance 

requirements and documents any limitations of the system.

EXHIBIT 3−5

Leak Detection Schematic

Make sure the vendor of the leak 

detection method you use has 

given you documentation that your 

leak detection system meets regulatory requirements for performance.

Don’t Forget...
3-6 Chapter 3 Underground Storage Ta

States are able to implement regulations equal to or more restrictive than the 

federal regulations noted above. Therefore, it is important to find out if there are

state or local agency requirements on the use of leak detection methods for USTs

that differ from those described here. For example, California requires owners 

and/or operators of UST systems installed before July 1, 2003, and located within

1,000 feet of a public drinking water well to perform enhanced leak detection. 

Enhanced leak detection is a test method that introduces a chemical additive

not normally found in the fuel into the tank and then monitors for that additive 

outside the tank walls.

3.3.5 Recordkeeping and Reporting

You must submit the following information to your regulatory agency:

  notification form within 30 days of a UST first being used. (Note that ma

states, such as Florida, require notification before tank installation.)

 Reports of all suspected releases, spills, and overfills exceeding 25 gallons or

that cause a sheen on surface water and confirmed releases within 24 hours.

  report summarizing the initial cleanup measures taken within 20 days of a

confirmed release.

Exhibit 3−6 lists the documentation that must be kept on-site and how long to 

keep it. These records are to be readily available for inspection

will likely require updating the 

registration.

Chapter 3 Underground Storage Tanks 

3.4 Biofuel Blend Compatibility for USTs

The chemical and physical properties of biofuels, such as ethanol and biodiesel,

may make them more aggressive to certain UST system materials than petroleum. So it is important that all UST system components in contact with ethano

or biodiesel blends are materially compatible with that fuel. PA publish

guidance in the July 5, 2011, Federal Register regarding compatibility of US

systems with biofuel blends. To be in compliance with 40 CFR 280.32, owner

and operators of UST systems storing ethanol-blended fuels greater than 10%

ethanol or biodiesel-blended fuels greater than 20% biodiesel must use compatible equipment. PA considers the following UST components to be potentia

susceptible to compatibility issues:

 Tank or internal tank linin

 Pipin

 Line leak detector

 Flexible connectors

 Drop tub

 Spill and overfill prevention equipment

 Submersible turbine pump and components

 Sealants (including pipe dope and thread sealant), fittings, gaskets, O-rings,

bushings, couplings, and boots

 Containment sumps (including submersible turbine sumps and underdispenser containment)

 Release detection floats, sensors, and probe

 Fill and riser caps

 Product shear valv

Here are some acceptable methods for owners and operators of UST systems storin

ethanol-blended fuels greater than 10% ethanol or biodiesel-blended fuels greater 

than 20% biodiesel to demonstrate compatibility under 40 CFR 280.32

 Use components that are certified or listed by a nationally recognized, 

independent testing laboratory (for example, Underwriters Laboratories [UL]) 

for use with the fuel stored.

 Use components approved by the manufacturer to be compatible with the 

fuel stored. PA considers acceptable forms of manufacturer approvals 

• Be in writing

• Indicate an affirmative statement of compatibility

• Specify the range of biofuel blends the component is compatible with

• Be from the equipment manufacturer, not from another entity (such as the 

installer or distributor)

 Use another method determined by the implementing agency to sufficiently 

protect human health and the environment. PA will work with states as th

evaluate other acceptable methods.

Underground product recovery 

tanks also need to comply with UST 

requirements in this chapter.

3.5 Leaking USTs

3.5.1 Spills, Overfills, and Confirmed Releases

If you have a confirmed petroleum release to groundwater, surface water, or soil, 

you must report it to the state or federal agency in charge of the UST program.

You are required to report within 24 hours or immediately, depending on the 

agency requirements. Spills and overfills resulting in a petroleum release to the 

environment of over 25 gallons must be reported (and cleaned up immediately). 

In addition, if your UST stores a hazardous substance, instead of petroleum,

and there is a release to the environment exceeding that substance’s reportable quantity (RQ), it must be reported to the UST program and the Nationa

Response Center (NRC). See Chapter 2, Incident and Spill Reporting for relea

reporting requirements and an explanation of RQs. For corrective actions, see

Chapter 8, Assessment and Cleanup.

3.5.2 Suspected Releases

You must immediately investigate and confirm all suspected releases from USTs

within 7 days. Conduct tank tightness testing to determine whether a leak 

exists. If test results indicate a leak, you must repair, replace, or upgrade the tank 

and begin corrective actions as described in Chapter 8, Assessment and Cleanup. 

If the test results do not indicate a leak and environmental contamination was 

not the reason for suspecting a release, no further investigation is required.

3.6 Tank Closure

Many people have been killed or injured while improperly closing or removing 

USTs. As described below, the regulations in 40 CFR 280 specify the followi

closure requirements for USTs

For temporary closure (for example, out-of-service tanks) of 12 months or less:

 Continue to use corrosion protection and leak detection systems during nonuse time (omit leak detection if the tank is empty).

 Leave vent lines open and functioning.

 Cap all other lines, pumps, manways, and ancillary equipment. 

For permanent closure:

 Notify your regulatory agency 30 days before closure

 Conduct a site assessment to determine if a leak has occurred, and take 

corrective actions if needed (see Chapter 8, Assessment and Cleanup).

 Use standard safety and disposal practices to remove remaining liquids and 

accumulated sludge. Use only trained personnel who follow accepted safety 

practices.

 Fill the cleaned tank with a harmless, inert solid material (such as sand) 

and leave the tank in place. Or excavate the emptied tank and dispose of it

properly. Note that some states require removal of the tank

 Keep the certified closure report on file for at least 3 years

Note that some states require trained and certified workers to perform certain

phases of UST work, such as closure

The UST program defines USTs 

differently than the SPCC rule does. 

The UST program considers a UST 

to be a tank and any underground 

piping that has at least 10% of its 

combined volume underground.

However, under the SPCC rule, only 

completely buried tanks subject to 

the technical UST program requirements are exempt from the rule. 

Any tanks that are not completely 

buried are considered aboveground 

storage tanks and subject to the 

SPCC rule.

3.7 State Requirements

Currently 38 states, the District of Columbia, and Puerto Rico hae EPA app

to administer the UST program: Alabama, Arkansas, Colorado, Connecticu

Delaware, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Louisiana, Mai

Maryland, Massachusetts, Minnesota, Mississippi, Missouri, Montana, Nebraska,

Nevada, New Hampshire, New Mexico, North Carolina, North Dakota, Ok

Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennes

Texas, Utah, Vermont, Virginia, Washington, and West Virginia. All other states ma

have state requirements for USTs even though they do not haveEPA approval

administer their federal UST program

Many states have adopted UST requirements that are more stringent than the

federal rules. Be sure to check your state UST regulations. See Appendix E for a list

of regional PA and state contacts for USTs and LUSTs. See Appendix 3-2 for a 

of state UST regulations and associated websites

Some examples of differing state requirements are:

 Connecticut, Idaho, Illinois, Rhode Island, Vermont, and Wisconsin have more

stringent or differing release detection testing requirements.

 Missouri requires all metal components in contact with an electrolyte 

including but not limited to soil, backfill, and/or water to be cathodically 

protected.

 Wisconsin has more stringent requirements for overfill prevention 

equipment.

 In California, service activities related to UST monitoring system equipment,

such as servicing electronic consoles for leak detection monitoring, must be 

performed by a qualified service technician meeting specific licensing and 

training requirements.

 The following states provide biofuel storage guidance or have application

processes for approval of storing biofuel in USTs: Arizona, California

Colorado, Delaware, Iowa, Maryland, Minnesota, Missouri, New Hampshir

North Carolina, Oregon, South Carolina, Tennessee, Vermont, Washingto

and Wisconsin.

 Note that some states (for example, Georgia and Alabama) require closu

assessments be submitted to the state agency.

As a result of the Energy Policy Act 

of 2005, most states receiving federal money made significant changes 

that affect owners or operators of 

USTs:

 Established minimum requirements for delivery prohibition

 Required state agency UST inspections every 3 years

 Secondary containment and 

interstitial monitoring operator 

training for new and repaired 

UST systems within 1,000 feet of a 

community water supply system

Check your state regulations for 

these requirements.
