Re: Closure Plan Approval for Petroleum Storage Tanks
Maverik #145, located at 95 North Main Street, Centerville, Utah
Facility Identification No. 3000026

Dear Mr. Stewart:

The Closure Plan for the above-referenced facility, received by the Division of
Environmental Response and Remediation (DERR) on September 4, 2024, has been approved
subject to the noted modifications, if any. The DERR office must be notified three (3) business days
before beginning closure activities. The local fire department and other local agencies may have
additional requirements for closure or may charge inspection fees.

The Closure Plan Approval is effective for a period of one year from the date of approval.
If closure does not take place within one year, submittal of a new Closure Plan will be required,
unless otherwise approved by the Division Director.

Any change to the approved Closure Plan must be submitted, in writing, and approved by
the Division Director before implementation. If contamination is suspected or found during closure
activities, you must report it to the DERR at [phone] within 24 hours of discovery.

Enclosed is a copy of the Closure Notice Form, which must be completed and submitted to
the Division Director after the closure is performed. Please submit the environmental and Unified
Soil Classification sample analysis data and chain-of-custody forms with the Closure Notice as soon
as possible, but no later than 90 days after tank closure. Also, a final Site Plat that meets the
requirements outlined in R311-204-4(2)(b) must be submitted with the Closure Notice.

Facility ID# 3000026

If you have any questions regarding this matter, please contact Gary Harris, the DERR
project manager, at [phone].

SITE ASSESSMENT
A site assessment must be performed for all UST closures and change-in-service. Site assessments must be performed as outlined in 40 CFR
280.72 and R311-205 (U.A.C.). If contamination is suspected, additional samples must be collected at the location 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. Soil and groundwater samples must be analyzed for the compounds shown in the following table, using appropriate lab
methods.

•Dual column confirmation may not be required for TPH and BTEXN/MTBE analysis.
•A micro-extraction or scale-down technique may be used for aqueous samples, but only for the determination of extractable TPH as diesel range
organics (C10 – C28).
•Hexane may be used as an extraction solvent.
•*Silica Gel Treatment (SGT) may be used in the determination of Total Recoverable Petroleum Hydrocarbons.
NOTE: The sample preparation method and any modification(s) to a certified method must be reported by the laboratory.

All materials generated from UST closures must be managed and disposed in a manner that does not place those materials in direct contact
with the environment. On-site stockpiling of contaminated soils may be required prior to any soil management activities. Any person
providing remedial assistance for a fee, including aeration and over-excavation (of more than 50 yd3), must be a Certified UST Consultant.
Contaminated soils generated as part of tank removal are to be disposed at the following facility: E.T. Technologies
