What is an Underground Storage Tank (UST)?

The state's definition of a UST is outlined under AS 46.03.450(9). State statute defines a UST as one or more stationary devices, including underground pipes connected to the devices, that is designed to contain an accumulation of petroleum, the volume of which, including the volume of underground pipes, is 10% or more beneath the surface of the ground.

This definition does not include a tank storing heating oil used on the same premises where the tank is stored. Information about Home Heating Oil Tanks can be found on Prevention Preparedness and Response's page for Home Heating Oil Tanks.

What does the UST Prevention Unit do?

The UST prevention unit oversees the operation and compliance of underground petroleum storage tanks under the requirements of 40 CFR 280 and 18 AAC 78 for the more than 800 active regulated tanks at 385 facilities located in Alaska.

The UST unit provides technical assistance, compliance, and enforcement to ensure regulated tanks are registered and have valid tags and decals; are installed, operated, and properly closed; suspected petroleum releases are investigated and reported; operators are adequately trained; meet financial responsibility requirements; and UST workers and inspectors are certified.
