Dear Ms. Mason:

The following document presents the results of semi-annual groundwater monitoring activities
performed at the above referenced site November 4-6, 2024. Utah Certified Soil and
Groundwater Samplers conducted all groundwater-sampling activities described in this report
under the direction of a Utah Certified Consultant.

INTRODUCTION AND BACKGROUND

This report summarizes the November 2024 semi-annual groundwater-monitoring event
conducted by Atlas Technical Consultants (Atlas) on behalf of Phillips 66 Company (P66) at the
North Salt Lake Products Terminal.

The Terminal is located at 245 East 1100 North, North Salt Lake, Utah, and has been assigned
Division of Environmental Response and Remediation (DERR) Facility Identification #3000144
and Release Site #EKKH. The site represents the Terminal property and neighboring properties
included in the monitoring program. The Terminal is a bulk storage and distribution terminal for
Pioneer Pipeline, which transports gasoline, diesel, jet fuel, and fuel additives. The Terminal
has been in operation at its current location since 1953. Figure 1 presents a Site Map showing
site features, adjacent properties, and specific well and peizometer locations.

The November 2024 monitoring event included the collection of groundwater elevation data and
laboratory analyses of groundwater samples collected from the Terminal and adjacent
properties. The above mentioned measurements and samples were collected from 27
monitoring wells (MW -4R, MW -5R, MW -7, MW -8, MW -9, MW -12, MW -13, MW -16, MW -19,
MW -20, MW -22, MW-27, MW -28, MW -29, MW -31, MW -33, MW -36, MW -37, MW -38, MW -40,
MW -44, and MW -46), and five piezometers (GP-27, GP-34, GP-37, GP-40, and GP-45).
Monitoring well MW -30 was destroyed in 2023. GP-38 was clogged with debris and was unable
to be sampled. GP-37 was sampled in its place. Road base and a building were installed in the

area of MW -32 and the well could not be located. For the purpose of this report, both monitoring
wells and piezometers will be referred to as wells.

Groundwater Field Parameter Measurements, Well Purging Procedures, and Chemical
Ana lysis
Depth to water (DTW) was measured using an oil/water interface probe. Following field
measurements, each well to be sampled was purged a minimum of three well casing volumes of
groundwater or until dry. The wells were then allowed to recharge to within 90% of their pre-
purge volume. Groundwater samples were collected from the wells using new, factory sealed,
disposable bailers. All down-hole sampling equipment was decontaminated with an Alconox
wash and tap water rinse after each use. Purge water was poured on the ground and allowed to
evaporate.

Groundwater samples were collected in laboratory provided containers and placed on ice in an
insulated cooler. The samples were shipped under documented chain-of-custody to Utah-
certified Pace Analytical Laboratories for analyses of methyl t-butyl ether, benzene, toluene,
ethylbenzene, xylenes, and naphthalene (MBTEXN) using USEPA Method 8260B/5030B, and
TPH-GRO and TPH-DRO using USEPA Method 8015D. The laboratory results are summarized
in Table 1 and a copy of the laboratory report is included in Appendix A.

Discussion of Groundwater Field Parameter Results
Groundwater elevations measured during the November 2024 semi-annual monitoring event
were generally consistent with the historical seasonal variation. The hydraulic gradient was
measured at 0.019 ft/ft between MW -13 and MW -19 and is consistent with previous monitoring
events. Figure 2 presents the November 2024 groundwater table contours for the site. Free
product was not measured in any of the wells during the November 2024 sampling event.

Discussion of Groundwater Petroleum Hydrocarbon Chemical Analysis Results
All of the 27 wells sampled contained detectable concentrations of petroleum hydrocarbons,
most notably benzene, TPH-GRO, and TPH-DRO. An Iso-concentration map for benzene was
generated using data interpolation methodology (refer to Figure 3). Groundwater level and
volatile organic compounds (VOC) concentration vs. time graphs for monitoring wells MW -7,
MW -9, MW -12, MW -16 and MW -22 are presented in Figures 4 through 8, respectively. The
following impacts to groundwater were noted during the November 2024 monitoring event:

• The benzene Tier 1 Screening Level of 0.3 mg/L was exceeded in five of the on-site
wells sampled: MW -7 (1.950 mg/L), MW -8 (0.502 mg/L), MW -9 (0.742 mg/L), GP-34
(0.329 mg/L), and GP-37 (1.460 mg/L). The November 2024 laboratory results for the
samples collected from the off-site monitoring wells indicated the detection of benzene
above the Initial Screening Level (ISL) of 0.005 mg/L in eight of the wells sampled: MW -
16 (0.00802 mg/L), MW -19 (0.0201 mg/L), MW -29 (0.367 mg/L), MW -36 (0.166 mg/L),
MW -37 (0.00877 mg/L), MW -44 (0.0947 mg/L), MW -46 (0.492 mg/L), and GP-27
(0.0221 mg/L). Concentrations in MW -12, MW -16, MW -28, and MW -31 showed
decreases in benzene since the May 2024 sampling event; while MW -4R, MW -5R, MW -
7, MW -8, MW -9, MW -19, MW -22, MW -29, MW -36, MW -37, MW -38, MW -44, MW -46,
GP-27, GP-34, and GP-45 showed increases. The remaining wells remained below
laboratory detection limits or were not sampled in May 2024. A comparison of the
benzene concentrations from the May 2024 sampling event to the November 2024
sampling event is presented in Table 2.

• The TPH-GRO Tier 1 Screening Level of 10 mg/L was exceeded in on-site monitoring
wells MW -4R (13.500 mg/L) and MW -7 (29.800 mg/L). The TPH-GRO ISL of 1.0 mg/L
was exceeded in off-site wells MW -19 (1.160 mg/L), MW -29 (6.940 mg/L), MW -31
(3.460 mg/L), MW -36 (3.300 mg/L), MW -44 (2.150 mg/L), MW -46 (4.200 mg/L), and GP-
27 (7.690 mg/L). Decreases in TPH-GRO concentrations were observed in MW -5R,
MW -7, MW -8, MW -12, MW -16, and MW-38; while MW -4R, MW -9, MW -19, MW -22, MW -
28, MW -29, MW -31, MW -36, MW -37, MW -44, MW -46, GP-27, GP-34, and GP-40
showed decreases. The remaining wells remained below laboratory detection limits or
were not sampled in May 2024. A comparison of TPH-GRO concentrations from the May
2024 sampling event to the November 2024 sampling event is presented in Table 3.

• The TPH-DRO Tier 1 Screening Level of 10 mg/L was exceeded in on-site monitoring
well MW -4R (10.700 mg/L). The ISL of 1.0 mg/L was exceeded in off-site wells MW -19
(2.010 mg/L), MW -29 (3.500 mg/L), MW -36 (3.090 mg/L), MW -44 (1.640 mg/L), MW -46
(2.140 mg/L), and GP-27 (3.370 mg/L). Decreases in the TPH-DRO concentration was
observed in MW -7, MW -12, and MW-22; and increases were observed in MW -4R, MW -
5R, MW -8, MW -9, MW -16, MW -19, MW -27, MW -28, MW -29, MW -31, MW -33, MW -36,
MW -37, MW -38, MW -44, MW -46, GP-27, GP-34, GP-40, and GP-45. The remaining
wells remained below laboratory detection levels or were not sampled in May 2024. A
comparison of TPH-DRO concentrations from the May 2024 sampling event to the
November 2024 sampling event is presented in Table 4.

No other petroleum hydrocarbon impacts exceeded either the Tier 1 Screening Levels or ISLs.
Detectable concentrations of MBTEXN compounds were measured at multiple locations both on
and offsite (see Table 1).

The analytical laboratory report indicates that all of the samples submitted for analyses were
received in acceptable condition. Samples that were prepared and/or analyzed past holding
times as defined in the method were identified in Table 1 with a Q qualifier. A field duplicate
sample, identified as MW-7D, was collected from MW-7 to verify the laboratory's procedures
and accuracy. Concentrations measured in November 2024 were consistent with historical
values of MBTEXN, TPH-GRO, and TPH-DRO at these locations given the time of year and
current water elevations, and the shutdown of the remediation system in December 2018.

CONCLUSIONS AND RECOMMENDATIONS

Results of the November 2024 groundwater monitoring event indicate the continued presence of
petroleum hydrocarbon impacts to groundwater. Five of the wells on-site; MW -7, MW -8, MW -9,
GP-34, and GP-37 exceeded the Tier I Screening Level for benzene, and eight of the off-site
wells, MW -16, MW -19, MW -29, MW -36, MW -37, MW -44, MW -46, and GP-27 exceeded the ISL
for benzene.

On-site wells MW -4R and MW -7 exceeded the Tier 1 Screening Level for TPH-GRO, and off-
site wells MW -19, MW -29, MW -31, MW -36, MW -44, MW -46, and GP-27 exceeded the ISL of
1.0 mg/L. The TPH-DRO Tier 1 Screening Level was exceeded in on-site well MW -4R. The ISL
was exceeded in off-site wells MW -19, MW -29, MW -36, MW -44, MW -46, and GP-27.

Petroleum hydrocarbon impacts appear to continue to be greatest in the vicinity of the Manifold
and Valve Yard (MW -8 and MW -9), adjacent to the drainage ditch down gradient of the Truck

Loading Racks (MW-7); and off-site east of the UNIVAR Facility (between GP-27 and MW -46)
and furthest down gradient wells near the private residence (GP-16 and GP-19). The November
2024 data suggests decreases in concentrations exhibited during the monitoring event are in
part attributable to seasonal fluctuations in the water table elevation.

In late December 2018, with approval from the UDEQ, the remediation system at the site was
shut down to monitor potential rebound of groundwater impacts. The sampling event in
November 2024 represents the 13th groundwater sampling event since the system was shut
down. Review of the data collected in November 2024 and historical groundwater data indicate
that the groundwater plume has stabilized. Based upon review of the groundwater data, Atlas
recommends that the groundwater remediation system remain off and that the semi-annual
groundwater monitoring program continue at the site. The next semi-annual round of sampling
is scheduled for May 2025.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be
considered minimum values.
