Petroleum Storage Tank Branch

Attention: APST Regulation Begins July 2021

The Division of Environmental Response and Remediation (DERR) began regulating Aboveground Petroleum Storage Tanks (APSTs) starting July 1, 2021.

News and Announcements

PST Program

The Utah State Petroleum Storage Tank (PST) Program, administered by the Department of Environmental Quality, is responsible for protecting human health and the environment from the risks posed by leaking petroleum storage tanks.
The state’s Underground Storage Tank (UST) regulations were first established in 1986 in response to a federal mandate. These rules created a comprehensive program to oversee the entire lifecycle of underground storage tanks—including notification, installation, inspection, removal, and regulatory compliance for leak prevention and site remediation. The Underground Storage Tank Act of 1989 further clarified the responsibilities of governing authorities, set specific requirements for tank owners, and established the Petroleum Storage Tank (PST) Fund.

In 2021, new legislation expanded the Division of Environmental Response and Remediation’s (DERR) regulatory authority to include certain Aboveground Petroleum Storage Tanks (APSTs). As a result, regulated APST owners must now submit closure plans for any tank closures, upgrades, line replacements, or similar activities. Any releases from regulated APSTs fall under DERR authority, and PST reporting requirements and cleanup standards now apply.

Beginning in 2025, APST owners and operators are also required to notify the DERR of any ownership changes, new installations, or tank upgrades and repairs.

What is an Petroleum Storage Tank?

A Petroleum Storage Tank (PST) is a tank that is an Underground Storage Tank (UST) or an Above Ground Storage Tank (APST).

An UST is a tank system, including piping connected to the tank, that has at least 10 percent of its volume underground. Federal and state regulations apply only to those USTs containing petroleum products or certain hazardous chemicals. USTs not regulated include:

  • Farm or residential tanks 1,100 gallons or less, used non-commercially.
  • Tanks storing heating oil, used on the premises.
  • Flow-through process tanks.
  • Emergency spill and overflow tanks.
  • Tanks holding 110 gallons or less.
  • Others as described in the federal register.
  • Farm or residential tanks 1,100 gallons or less, used non-commercially.
  • Tanks storing heating oil, used on the premises.
  • Flow-through process tanks.
  • Emergency spill and overflow tanks.
  • Tanks holding 110 gallons or less.
  • Others as described in the federal register.

An APST is a storage tank that is less than 10 % buried in the ground and has attached underground piping or rests directly on the ground, contains regulated substances and has the capacity to hold 501 gallons or more. Sites not regulated include aboveground storage tanks:

  • At commercial airport for fueling
  • Used in farming or agriculture
  • Related to a Petroleum refining (SIC Code 2911)
  • At petroleum bulk stations and terminals (SIC Code 5171)
  • Related to oil or gas production and gathering operations
  • Used for heating oil on premises

Why are PSTs Regulated?

The Environmental Protection Agency (EPA) and the State of Utah, with the help of the regulated industry, developed regulations concerning PST owners and operators. The goals of these regulations include:

  • To prevent leaks and spills.
  • To find leaks and spills.
  • To correct the problems created by leaks and spills.
  • To ensure the owners and operators can pay for clean-up associated with leaking PSTs.
  • To ensure that Utah has a regulatory program that complies with the State and Federal regulations.

Utah obtains more than 50% of the population’s drinking water from groundwater. The regulations in place are meant to protect this valuable public resource. When an PST leaks, it becomes a Leaking Petroleum Storage Tank (LPST) and poses a risk to human health and the environment. The Petroleum Storage Tank Branch has two sections handling the cleanup of LPST sites. The Environmental Assurance Section handles the cleanup of PST sites on the State’s PST Fund. The Environmental Assistance Section handles the cleanup of PST sites that have private insurance or have no insurance.

Who Makes Up the Utah UST Program?

DERR Director

The Director of the Division of Environmental Response and Remediation is an individual who has the authority to administer the UST Program as established by the Utah Legislature. The Director answers to the Utah Solid and Hazardous Waste Control Board which consists of approximately ten individuals appointed by the Governor.

UST Section

The UST section of the Division of Environmental Response and Remediation, is a group of environmental scientists whose task is to oversee the regulated public in issues that concern the operational life of USTs up to proper closing of UST systems. The UST staff has tracked about 15,000 USTs and currently regulates approximately 4,300 USTs at more than 1,500 different facilities. UST staff members perform compliance inspections, issue compliance notices, and serve as expert witnesses at administrative hearings. Outreach classes and seminars are taught throughout the state.

LUST Section

The LUST section of DERR oversees remediation of contamination from USTs. LUST scientists and engineers review and establish clean-up guidelines. When responsible parties are not available or are unable to pay for the remediation of a LUST site, the LUST staff may use LUST-Trust money to define the degree of hazard, initiate abatement actions, and remediate the site. Funds spent will be recovered from responsible parties. Often, responsible parties seek the guidance of the LUST staff to insure clean-up in a timely and economical fashion.

Administrative Support Section

The administrative support section oversees the collection of UST fees and monitors expenditures. Accountants and technicians answer questions concerning billings and distribute funds as appropriate.

What are the Requirements for Owner/Operators of Underground Storage Tank Systems?

  • Notify the DERR of all regulated USTs with EPA Notification Form 7530-1 
  • Pay any applicable fees.
  • Obtain a Certificate of Compliance.
  • Maintain compliance with regulations.
  • Upgrade USTs when required.
  • Report any UST release to the DERR.
  • Remediate contamination.
  • Remove UST appropriately.

Petroleum Storage Tanks Amendments 2025

On February 27, 2025, Utah’s Governor Spencer Cox signed H.B. 18 Petroleum Storage Tank Amendments which was passed in the 2025 legislative session. These changes were the first to be made to the Petroleum Storage Tank Act since the addition of aboveground petroleum storage tanks (APST) regulations in the 2021 legislative session. Changes include:

  • New owners/operators of APSTs must notify the Division of Environmental Response and Remediation (DERR) no later than 30 days after change occurs.
  • An owner/operator must register APSTs with DERR at least 30 days before an installation.
  •  A petroleum storage tank installation company must now obtain an install permit for all PST installations at least 30 days before the install, including APSTs and pay fees at least 30-days before the install begins.
  • An Owner/Operator of both APSTs & USTs can now get a loan to upgrade, replace or permanently close a PST.

These changes are effective May 7, 2025. The Division of Environmental Response and Remediation (DERR) is currently drafting changes to R311, the Utah Petroleum Storage Tank (PST) rules to address these statutory changes. If you have any questions please contact David Wilson at (801) 536-4100.
