Aboveground Petroleum Storage Tanks (APST)

Due to legislation passed in the 2021 session, the Utah Department of Environmental Quality (DEQ), Division of Environmental Response and Remediation (DERR) began regulating Aboveground Petroleum Storage Tanks (APSTs) on May 5, 2021.

What is a regulated APST?

A petroleum storage tank greater than 500 gallons and meets one or both of the following:

  • If the APST rests on soil or gravel
  • If any portion of the piping is underground

APSTs not regulated include:

  • Less than 501 gallons
  • Commercial airport for fueling
  • Used in farming or agriculture
  • Petroleum refiner (SIC Code 2911)
  • Petroleum bulk stations and terminals (SIC Code 5171)
  • Related to oil or gas production and gathering operations
  • Used for heating oil on premises

Owners and Operators of regulated APSTs must notify the DERR by July 1, 2022 with the APST Notification Form.

Upon completion, please sign and date the form and return it to the DERR.

Either email it to: TankCompliance@utah.gov

or mail it to:

Division of Environmental Response and Remediation

Also, beginning May 5, 2021, all APSTs that are now regulated by DERR will be required to submit a closure plan for any closures, upgrades, line replacement, etc. Releases from regulated APSTs will now be regulated by the DERR and the Underground Storage Tank reporting requirements and cleanup standards will apply.
