Closure Plan Requirements

R311-204, Utah Administrative Code (U.A.C.), requires Underground Storage Tank (UST) owners and operators to submit a Closure Plan outlining the details of the UST closure to the Executive Secretary of the Utah Solid and Hazardous Waste Control Board.

Completed Closure Plan

The Owners and Operators (O/O) must submit to the Division of Environmental Response and Remediation (DERR) a completed “Closure Plan” which must be approved before commencing closure of the UST. A contractor may complete the closure plan, however, the O/O is responsible for compliance with the UST rules and regulations.

Closure In-place or Change in Service

For closure in-place or change in service, the Closure Plan must be submitted and approved prior to completing the site assessment.

Period of Validity

The approved Closure Plan is valid for one year from the approval date. If closure does not take place within one year, the O/O must submit a new Closure Plan for approval.


The O/O must notify the Local Health and Fire Departments and DERR/UST at least 72 hours prior to starting closure activities.

Certified UST Remover and Sampler

The certified UST remover and sampler performing the closure must have a current Utah certification and follow the approved Closure Plan. Changes to an approved plan must be submitted in writing to the Executive Secretary and approved before closure.

Copy of Approved Closure Plan

The O/O must have a copy of the approved Closure Plan on-site during closure activities.

Completion of Site Assessment

The O/O must ensure the completion of a site assessment in accordance with 40CFR 280.72 and R311-205, U.A.C. Indicate the proposed sample locations on the Facility Site Plat of the Closure Plan and complete the Sample Information Table.


If contamination is encountered or suspected at locations other than the approved sample locations, additional samples must be collected at the location(s) where contamination is most likely to be present.

If groundwater is encountered a soil sample must be collected, in the unsaturated zone, in addition to each groundwater sample.

The O/O must report suspected or confirmed contamination (any amount) to the Executive Secretary by reporting to the DERR/Leaking Underground Storage Tanks (LUST) section at (801) 536-4100 within 24 hours of discovery.

Closure Notice

The O/O must submit to the DERR a Closure Notice within 90 days after the tank closure. The Closure Notice should include:

  • A properly completed Closure Notice Form signed by the owner and certified groundwater and soil sampler.
  • An updated Site Plat and a Sample Information Table with actual depths and locations of all samples, including depth of ground water.
  • Analytical results of samples.
  • A Chain of Custody Form.


The O/O must pay registration and PST Fund fees, for the assessment period in which the tank is closed, and all other unpaid fees.

If contamination is suspected or confirmed during UST closure activities, or is based on analytical results, the O/O may receive a reporting and remediation schedule from the DERR/LUST section, outlining their obligation to characterize and possibly remediate the release.

Any person providing remedial assistance for a fee, including over-excavation (of more than 50 yd3) and aeration, must be a Certified UST Consultant (a list is available from DERR).

Expenses to be applied toward the Petroleum Storage Tank (PST) Fund deductible must meet the same test of reasonable, customary, and legitimate as expenses submitted for reimbursement. For expenses above the $10,000 deductible to be eligible for reimbursement from the PST Fund, all work plans and budgets must be approved the State Project Manager before any work begins.

Refer questions concerning the Closure Plan approval process to the DERR/UST section at (801) 536-4100.
