What USTs Are Included? An UST system is defined as any one or 

combination of tanks that is used to contain an accumulation of regulated 

substances, and whose volume (including connected underground piping) is 10 

percent or more beneath the ground. Regulated USTs store petroleum or 

hazardous substances (see What Substances Are Covered below). This 

includes UST systems with field-constructed tanks and airport hydrant fuel 

distribution systems.

What Tanks Are Excluded From Notification (see § 280.10 and § 280.12)?

 Tanks removed from the ground before May 8, 1986;

 Farm or residential tanks of 1,100 gallons or less capacity storing motor fuel for 

noncommercial purposes;

 Tanks storing heating oil for use on the premises where stored;

 Septic tanks;

 Certain pipeline facilities regulated under chapters 601 and 603 of Title 49;

 Surface impoundments, pits, ponds, or lagoons;

 Storm water or wastewater collection systems;

 Flow-through process tanks;

 Liquid traps or associated gathering lines directly related to oil or gas production 

and gathering operations;

 Tanks on or above the floor of underground areas, such as basements or tunnels;

 Tanks with a capacity of 110 gallons or less;

 Wastewater treatment tank systems;

 UST systems containing radioactive material that are regulated under the Atomic 

Energy Act of 1954;

 UST systems that are part of an emergency generator system at nuclear power 

generation facilities regulated by the Nuclear Regulatory Commission under 10 

CFR part 50.

What Substances Are Covered? The notification requirements apply to 

USTs containing petroleum or certain hazardous substances. Petroleum 

includes gasoline, used oil, diesel fuel, crude oil or any fraction thereof which is 

liquid at standard conditions of temperature and pressure (60 degrees 

Fahrenheit and 14.7 pounds per square inch absolute). Hazardous 

substances are those found in Section 101 (14) of the Comprehensive 

Environmental Response, Compensation and Liability Act of 1980, with the 

exception of those substances regulated as hazardous waste under Subtitle C 

of the Resource Conservation and Recovery Act.

When And Who To Notify? Owners who bring USTs into use after May 8, 

1986 must submit this notification form to the implementing agency within 30 

days of bringing the UST into use. If the implementing agency requires 

notification of any amendments to the facility, send information to the 

implementing agency immediately.

Penalties: Any owner who knowingly fails to notify or submits false 

information shall be subject to a civil penalty not to exceed $16,000 for each 

tank for which notification is not given or for which false information is given.

INSTRUCTIONS AND GENERAL INFORMATION

Please type or print in ink. Also, be sure you have signatures in ink 

for sections VIII and XI. Complete a notification form for each location 

containing underground storage tanks. If more than 5 tanks are 

owned at this location, you may photocopy pages 3 through 6 and use 

them for additional tanks. 

The primary purpose of this notification form is to provide information 

about the installation, existence, changes to, and closure of 

underground storage tank systems (USTs) that store or have stored 

petroleum or hazardous substances. The information you provide will 

be based on reasonably available records, or in the absence of such 

records, your knowledge or recollection.

Federal law requires UST owners to use this notification form for 

all USTs storing regulated substances that are brought into use 

after May 8, 1986, or USTs in the ground as of May 8, 1986 that 

have stored regulated substances at any time since January 1, 

1974. The information requested is required by Section 9002 of 

the Solid Waste Disposal Act (SWDA), as amended.

Who Must Notify? 40 CFR part 280, as amended, requires owners 

of USTs that store regulated substances (unless exempted) to notify 

implementing agencies of the existence of their USTs. Owner is 

defined as:



In the case of an UST in use on November 8, 1984, or brought into use 

after that date, any person who owns an UST used for storage, use, or 

dispensing of regulated substances; or



In the case of an UST in use before November 8, 1984, but no longer in 

use on that date, any person who owned the UST immediately before its 

discontinuation.

Also, owners of previously deferred UST systems with fieldconstructed tanks and airport hydrant fuel distribution systems in the 

ground as of [DATE of REG] must submit a one-time notification of 

existence by [ENTER DATE three years after REG]. Owners of UST 

systems with field-constructed tanks and airport hydrant fuel 

distribution systems brought into use after [DATE of REG] are 

considered new facilities and must follow the same notification 

requirements as all other UST owners.

I. OWNERSHIP OF USTs II. LOCATION OF USTs

Owner Name (Corporation, Individual, Public Agency, Or Other Entity) If required by implementing agency, give the geographic location of USTs either in decimal 

degrees, or degrees, minutes, and seconds. Example: Latitude: 36.123480 (or 36 7'
