RE: Corrective Action Progress and Ground Water Monitoring Report
Maverik Store #319
891 East Main Street, Price, Utah 84501
Facility ID# 5000038, Release Site MTQ

Dear Mr. Crim:

Maverik, Inc. is pleased to provide results from the annual groundwater monitoring event performed
in 2023 at Maverik Store #319 in Price, Utah. Sampling was conducted in compliance with the site
Corrective Action Plan (CAP), originally approved by DERR on February 4, 2016, and revised in
February 2022. Details of the groundwater monitoring activities and results are discussed in this
report.

GROUNDWATER SAMPLING AND ANALYSIS

Groundwater monitoring field activities were performed on October 29-30, 2023, by Maverik
personnel according to standard U.S. Environmental Protection Agency (EPA) and Utah Division of
Environmental Response and Remediation (DERR) protocols. Mark Stewart, a Utah certified soil
and groundwater sampler (GS-1842), gauged the monitoring wells and collected groundwater
samples for analysis. Groundwater samples were collected from 10 wells (MW-1a, MW-3a, MW-7a,
MW-8, MW-9, MW-11, MW-12, MW-14, MW-16, and SVE-20) for laboratory analysis. Monitoring well
locations sampled are shown on the attached Figure 1.

Chemtech-Ford Analytical Laboratories of Sandy, Utah performed the groundwater analyses.
Samples were analyzed for benzene, toluene, ethylbenzene, total xylenes, naphthalene (BTEXN),
and methyl tertiary-butyl ether (MTBE), total petroleum hydrocarbons – gasoline range organics
(TPH-GRO) according to EPA SW-846 Method 8260D. Total petroleum hydrocarbons - diesel range
organics (TPH-DRO) according to EPA SW-846 Method 8015D was mistakenly not analyzed. In
addition, alkalinity, redox potential, iron 1, nitrate, and sulfate were also analyzed using industry
standard laboratory methods. Dissolved oxygen (D.O.) was measured in the field. Chain-of-Custody
protocol was observed.

GROUNDWATER MONITORING RESULTS

Static Water Level Evaluation

Groundwater flow direction at the site was in the southeast direction (Figure 1) which correlates with
well with previous studies. Groundwater elevation data is summarized in Table 1.

Groundwater Quality Evaluation

Groundwater analytical results are summarized in Table 2. Groundwater contamination above the
Risk-Based Corrective Action (RBCA) Tier 1 Screening Levels (SLs) exists in the following five wells:

MW-1a: (benzene – 15.7 mg/L, xylenes – 11.0, TPH-GRO – 30.4 mg/L); MW-3a: (benzene –
0.485 mg/L), MW-7a: (benzene – 8.46 mg/L, toluene – 9.6 mg/L, xylenes – 12.0 mg/L, TPH-
GRO – 42.7 mg/L); MW-13: (benzene – 6.54 mg/L) and SVE-20: (benzene – 0.769 mg/L).

Groundwater samples from MW-8, MW-9, MW-11, MW-12, MW-14, and MW-16 showed no
contamination above (and generally significantly below) RBCA Tier 1 SLs for any of the constituents
analyzed.

1 Note that the analytical laboratory reported total iron rather than differentiating the two oxidation states of iron,
ferrous and ferric.

There does not appear to be any conclusive results from the 2023 data as compared to 2020 through
2022 results. While concentrations of some analytes at some of the wells went down, some analyte
concentrations in other wells saw an increase.

MONITORED NATURAL ATTENUATION

The corrective action approach for the site as specified in the CAP is Monitored Natural Attenuation.
Natural attenuation at the site is evaluated using the ASTM (E1943-98(2015)), DERR (2015), and
USEPA (1999) guidelines and are summarized below:

Plume Definition

The primary line of evidence for natural attenuation is to define the plume as stable, shrinking, or
expanding. A plume is stable when concentrations at points within the plume are relatively uniform
over time. A stable or shrinking plume is evidence of natural attenuation. The source of constituents
of concern may persist in soils at the water table but the natural attenuation rate approximately
equals the mass loading rate for constituents of concern to groundwater. If a plume is expanding but
at a rate lower than the groundwater velocity, the risk reduction and performance goals may still be
met depending on the presence and location of receptors. A shrinking plume exists when the
contamination front is receding back to the source and concentrations in individual wells and total
contaminant mass are decreasing over time.

In general, a stable or shrinking plume is clear evidence of natural attenuation occurring at a site.
However, even in the case of an expanding plume, the influence of natural attenuation can be
demonstrated in many cases. Based on the groundwater quality evaluation in the previous section,
the plume at the site appears to generally be stable and not expanding. Therefore, it can be
reasonably assumed that natural attenuation is playing at least some role in limiting contaminant
migration at the site.

Geochemical Indicators

An inverse correlation of D.O. to BTEX concentrations typically indicates that aerobic biodegradation
is occurring at a given site. This relationship may also be expressed as depressed or non-detectable
levels of D.O. throughout the plume. On the other hand, alternate electron acceptor (nitrate, ferrous
and ferric ions, and sulfate) concentration data are used to monitor anaerobic biodegradation, if any.

D.O concentration measurements appear to have, in general, increased slightly in 2023 versus the
past few previous years. However, no clear pattern is apparent from comparison to BTEX
concentrations to indicate that appreciable aerobic biodegradation is occurring. Other geochemical
indicator results presented in Table 3 are, for the most part, stable over at least the last four years
and therefore do no indicate that noticeable anaerobic biodegradation is occurring.

FUTURE COURSE OF ACTION

Contamination levels fluctuated through the last 5 years of monitoring at the site. As such, with the
exception that a relatively stable plume is evident as discussed in the Monitored Natural Attenuation
section, few conclusions can be drawn from the available data. Maverik requests, as discussed in
the revised CAP, to continue to sample the ten wells (MW-1a, MW-3a, MW-7a, MW-8, MW-9, MW-
11, MW-12 through MW-14, and MW-16) on an annual basis until a different course of action (such
as UST removal/soil overexcavation to remove source material) is determined by Maverik in
consultation with DERR. The next sampling event will take place no later than November 2024,
unless UST removal dictates a change of plans.

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
IHT = Sample received with insufficent holding time. As a result, the sample was prepared or analyzed outside of method recommended holding time.
R-05 = The sample was diluted due to the presence of high levels of non-target analytes resulting in elevated reporting limits.
SPH = Sample submitted past method specified holding time.
