RE: Corrective Action Report
Maverik Store #289
951 West Highway 40, Vernal, UT 84078
Facility ID# 9000309, UST Release Site MXL

Dear Ms. Brennan:

Transmitted herewith please find the corrective actions implemented and laboratory analysis
results for samples collected during the tank removal activities completed in late
November/early December 2023 at the former Maverik store #289 located in Vernal, Utah. UST
closure and sampling activities were conducted as per the approved Closure Plan and
documented in the UST Removal Report/Closure Notice which was recently submitted to the
DERR.

Background
A release was identified for this site in 2012 and subsequently Release ID MXL was assigned to
the site by DERR. Since that time, there have been multiple years’ worth of site investigations
and laboratory analytical data. Due to the corrective actions employed in the past, contaminant
concentrations had decreased substantially throughout the site. However, as of the last
groundwater monitoring event conducted prior to UST removal (conducted on June 26, 2023,
there was still one analyte (benzene) that was above the Utah Risk-Based Corrective Action
Tier 1 Screening Levels (RBCA Tier 1 SLs) in two wells, MW-2 and MW-4 (see Figure 1).

Corrective Actions
Store operations ceased on September 7, 2023, and the USTs, dispenser islands, and canopies
were removed in mid-November 2023. To facilitate site remediation during the site closure, the
following corrective actions were proposed by Maverik, and subsequently approved by the
DERR.

1. Soil over-excavation and off-site disposal,
2. Groundwater recovery and off-site disposal, and
3. Application of Klozur One® for chemical oxidation and enhanced bioremediation

A Public Notice identifying the above measures was hand delivered to all the neighboring
properties with the potential to be impacted on October 27, 2023. Tank removal/corrective
action work started on November 15, 2023, and between November 15 and 17, 2023, three (3)
existing tanks, four (4) dispenser islands, and associated piping were removed and disposed
off-site.

Closure Samples
Seven (7) closure soil samples were collected for laboratory analysis, just above the water
table, at approximately 11 feet below ground surface (bgs) along the walls of the UST basins
and four (4) additional soil samples were collected at approximately 3 feet bgs under the
removed dispenser islands. Five (5) groundwater samples were collected in the tank
excavations at approximately 12 feet bgs. All samples were taken to Chemtech-Ford Analytical
Laboratories of Sandy, Utah, for soil and groundwater analyses, following chain-of-custody
protocols. Samples were analyzed for benzene, toluene, ethylbenzene, total xylenes,
naphthalene (BTEXN), methyl tertiary-butyl ether (MTBE), total petroleum hydrocarbons -
gasoline range organics (TPH-GRO) and TPH - diesel range organics (TPH-DRO) according to
EPA SW-846 Methods 8260 and 8015.

Overexcavation, Groundwater Recovery and Confirmation Sampling
Soil was also field analyzed using a MiniRAE 3000+ portable VOC meter/photoionization detector
(PID), calibrated to 100 parts per million (ppm) isobutylene standard. A soil sample was placed into a
Ms. Eileen Brennan
February 2, 2024
Page 3
24-02-02 Vernal 289 proposed CAP report
plastic zip lock bag, sealed, and warmed. The sealed bag was opened slightly to insert the tip of the
VOC meter to check for the presence of hydrocarbon vapors. PID readings at multiple locations,
primarily on the east side of the northernmost tank basin, identified significant vapor readings along
with a very noticeable hydrocarbon smell and soil discoloration. As such, over-excavation activities
were initiated.

The excavation was slowly expanded until clean edges (as evident by relatively low PID readings)
appeared to be reached. Confirmation soil samples were then collected at four locations at
approximately 11 feet bgs. Confirmation sample locations are shown in Figure 2. A total of 556.5
tons of soil was over-excavated and disposed off-site at the Uintah County Landfill in Vernal, UT
(weight tickets attached).

In addition, a vacuum truck was mobilized to the site to remove groundwater from the northernmost
UST basin. Approximately 2800 gallons of groundwater was extracted into a vacuum truck and taken
to Lapoint Recycling in Lapoint, UT for disposal (manifest attached). After which, one additional
groundwater sample/confirmation sample (see Figure 2) was taken of the recharged water within the
UST basin.

Analytical Results
Closure Samples
Except for samples SS-2 and SS-5, laboratory analytical results for all closure samples were all either
non-detect or below initial screening levels (ISLs) for soil. SS-2 samples were above ISLs – but
below RBCA Tier 1 SLs - for ethylbenzene, TPH-GRO, and TPH-DRO (at 17.3 mg/kg, 805 mg/kg,
and 3140 mg/kg, respectively). SS-5 samples were above the ISL for TPH-DRO (at 1090 mg/kg –
see Table 1, attached).

Groundwater laboratory analytical results for multiple samples were above ISLs, and a few were
above RBCA Tier 1 SLs; for benzene, TPH-GRO and TPH-DRO and, with one exception (GW-3A,
toluene @1.75 mg/L), were below ISLs for all other constituents analyzed (see Table 2). Benzene
was shown to be above RBCA Tier 1 SLs in samples GW-1 (@ 0.478 mg/L) and GW-3A (@ 0.796
Ms. Eileen Brennan

mg/L). TPH-DRO was above RBCA Tier 1 SLs in samples GW-2 (@ 10.2 mg/L) and GW-4 (@ 73.0
mg/L).

Confirmation Samples
All four soil confirmation samples were either non-detect or below, generally significantly below, ISLs
for soil. The one confirmation groundwater sample gathered, identified as GW Confirm, was non-
detect for all constituents except TPH-DRO (which was slightly above the ISL @1.2 mg/L). Please
refer to Table 3 for confirmation sampling results.

Application of Chemical Oxidation
As per the approved CAP, prior to backfill with clean imported material, Maverik applied Klozur®
One in the tank excavation for chemical oxidation and enhanced bioremediation. As described
in the CAP, Klozur® One is composed of soluble sodium persulfate which when dissolved can
persist for weeks to months after an application to treat residual contaminants, including
hydrocarbon components. Six 55.1 lb. bags of the dry product were mixed with the
recommended amount of water (approximately 130 gal. of water/bag of Klozur® One) and
liberally applied to the exposed groundwater surface and excavation sidewalls prior to backfill.

Installation of New Monitoring Wells
Upon completion of the soil over-excavation and recovery of contaminated groundwater, three
(3) groundwater monitoring wells (15 feet deep, 4-inch diameter, Schedule 40 PVC, with 10 feet
of 0.020 screen) were installed, along the tank excavation. The reasons for installing these three
wells were first, to replace wells that were destroyed during the soil over-excavation activities;
and second, to use them in the future as a conduit to the tank basin for sampling and/or
injection of chemicals such as Klozur® One for chemical oxidation and enhanced
bioremediation, if needs be. The approximate locations of these wells are found in Figure 3.

Conclusions and Recommendations
As evidenced by the laboratory results of the confirmation soil and groundwater samples
collected following the corrective actions implemented at the site, we believe that the vast
majority, if not all, of the source of contamination is eliminated from the site. We suggest that
Ms. Eileen Brennan
February 2, 2024
Page 5
24-02-02 Vernal 289 proposed CAP report
Maverik collects a round of confirmation groundwater samples in the spring or summer of 2024
from the five (5) existing wells that are likely to still be in place (MW-1, MW-5, MW-6, MW-7,
MW-8) along with the three new wells that were just installed.

We appreciate your assistance with this site. Please contact me at 801.438.4884 should you
have any questions.

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS
QM-RPD = The recovery was outside acceptance limits for the MS and/or MSD. The RPD between the MS and MSD was acceptable and indicates the recovery
is due to matrix interference. The batch was accepted based on the acceptable recovery of the LCS and the RPD.

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J-LOW-C = Estimated low due to low recovery of CCV
MS-Low = Estimated low due to Matrix Spike recovery.
