Aboveground Petroleum Storage Tanks (APST)

Aboveground Petroleum Storage Tank Financial Responsibility and Certificate of Compliance Requirements

Due to legislation passed in the 2021 session, DERR began regulating specific types of Aboveground Petroleum Storage Tanks (APSTs) on May 5, 2021. By statute (19-6-407(2)), owners of regulated APSTs must notify the Director of their location via the “Utah Notification for Aboveground Petroleum Storage Tanks” form. Upon notification, a processing fee of $250 shall be assessed to the owner. By June 30, 2023, APST owners must demonstrate financial responsibility and obtain a Certificate of Compliance. Regulated APSTs that do not register and obtain a Certificate of Compliance by June 30, 2023, will also be subject to enforcement actions, penalties, and delivery prohibition.

To qualify for a certificate of compliance the AST owner/operator must complete and submit the following (R311-206-3):

  1. Payment of annual registration fee ($110 per tank or $220 per tank if not participating in the Environmental Assurance Program (EAP))
  2. Payment of annual PST fund fee if participating in the EAP ($150 per tank, or $450 per tank if you don’t submit annual throughput or if your annual throughput is less than 70,000 gallons);
  3. Certificate of Compliance Application;
  4. Previous Pollution Incident form;
  5. Financial Responsibility Declaration
  6. Tank Tightness Test(s) performed in the last six months;

  7. Line Tightness Test(s) performed in the last six months;
  8. Spill Bucket Test(s) performed in the last six months;
  9. As-built drawing or site plat;

Site assessments for regulated APST facilities participating in the EAP are optional. If a site assessment is not conducted, new releases from a documented, known source are 100% covered starting day one of participation. Historic contamination discovered after 10-years of continuous coverage will also be 100% covered. Non-regulated APSTs must perform a site assessment and historic impacts are not covered.

*Note – Overfill, cathodic protection, and line leak detector tests will be required by owners participating in the Environmental Assurance Program starting 7/1/2026.
