1.0 Introduction
1.1 Site Description
Site Name Former Murray Fleet Facility; Release Site NCD
Site Location/Address 4400 South Main Street, Murray, Utah
Facility Identification No. 4000598, Release Site NCD
General Site
Description
The entire site is approximately 1.94 acres occupying one
parcel. The previous on-site building has been demolished,
and the entire site is currently under development.
Exhibit 1 (Appendix A) illustrates the approximate location of this parcel in relation to the
surrounding area.Exhibit 2 is a site diagram indicating the current and historic excavation
areas and approximate location of the newly installed groundwater monitoring well. The
facility had previously been operated by US WEST, Qwest Communications, and CenturyLink
(now Lumen).
Two petroleum underground storage tank (UST) releases reported to the Utah Department
of Environmental Quality (UDEQ) Division of Environmental Response and Remediation
(DERR) were identified at the facility during ownership and operation by Lumen. One of the
releases, Release HDA, involved a former gasoline and diesel fuel UST area in the northern
portion of the site, and the second release, Release NCD, involved a former used oil UST in
the southern portion of the site. Site investigations, groundwater monitoring, and
remediation activities to address the releases were conducted from early 1990s to the
middle 2010s. A corrective action was performed in 2013 with removal of impacted
subsurface soils, and post-remediation reports detailing this work in both release areas were
submitted to DERR. Release HDA received regulatory “No Further Action” status from the
DERR in March 2014.
A portion of the impacted soils of Release NCD could not be removed and was left in place
below the western portion of the facility’s former maintenance building. DERR agreed to
wait until the building located above a portion of Release NCD was demolished prior to
requiring further remedial action in that area.
The property is now owned by Evergreen-45th & Main Land, LLC, who is currently
redeveloping the property. A request for a Corrective Action Plan Requirements letter (dated
May 26, 2022) was issued by DERR to Lumen, and Terracon developed a Corrective Action
Plan (CAP; dated May 17, 2023). The CAP was approved by DERR in a letter dated August
1, 2023, and site work by the current owner was initiated in August 2024.

Facilities | Environmental | Geotechnical | Materials 2
In August 2024, the building covering the former Release Site NCD area was demolished to
redevelop the area.
Soil excavation, transportation, disposal, and groundwater treatment were conducted at the
site between August 16, 2024, and August 23, 2024 following the CAP. Confirmation soil
samples collected from each of the four sidewalls and one from the floor of the excavation
indicated that concentrations of petroleum hydrocarbons in soil at the extent of excavation
were below DERR’s Initial Screening Levels (ISLs).
A Corrective Action Implementation Report was issued by Terracon on September 16, 2024,
detailing the remediation work conducted at the site. The DERR issued a letter dated
September 19, 2024 (Appendix C), that indicated post-remedial groundwater monitoring
would be required to evaluate the effectiveness of the remedial action. DERR requires that
Groundwater monitoring continue until two consecutive events indicate that petroleum
impacts to the groundwater are below DERR’s ISLs.
Terracon submitted a Monitoring Well Installation Work Plan for the site (October 7, 2024)
that proposed the installation and sampling of one groundwater monitoring well in the
vicinity of the recent excavation and remediation area. The Work Plan was approved by the
DERR on October 11, 2024.
This report documents the results of two consecutive quarters of groundwater monitoring at
the site.
1.2 Scope of Services
The Scope of Services outline the installation and sampling of one groundwater monitoring
well to assess the current groundwater conditions after the recent excavation and
remediation work conducted at the site. The Post Remediation Groundwater Monitoring
request issued by DERR requires that groundwater monitoring should continue until two
consecutive sampling events indicate petroleum impacts to the groundwater are below ISLs.
The first groundwater sampling event was conducted on October 30, 2024. The second
sampling event was conducted on January 28, 2025.
1.3 Standard of Care
Terracon’s services were performed consistent with generally accepted practices of the
profession undertaken in similar studies in the same geographical area during the same
time period. Please note that Terracon does not warrant the work of laboratories, regulatory
agencies, or other third parties supplying information used to prepare the report. These
services were performed in accordance with the Scope of Services agreed with you, our
client, as reflected in our proposal, and were not restricted by ASTM E1903-19.

2.0 Monitoring Well Installation
Prior to monitoring well drilling and installation, the public utility location service (Blue
Stakes of Utah) was notified at least 48 hours prior to digging or drilling as required by law
and site access was obtained from the current site owner. In addition, a subcontracted
private utility location service, Direct Push Services, was used to identify and mark
subsurface utilities around the well location. The groundwater monitoring well was drilled by
Direct Push Services on October 25, 2024, using a direct-push (Geoprobe) drill rig. The
monitoring well was drilled to an approximate depth of 15 feet below ground surface (bgs).
The monitoring well was constructed as follows:
installation of 10 feet of 2-inch diameter (15–5 feet bgs), 0.010-inch machine slotted
polyvinyl chloride (PVC) well screen with a threaded bottom cap
installation of 2-inch diameter, threaded, flush-joint PVC riser pipe to the surface
addition of silica sand pack for annular sand pack around the well screen from the
bottom of the boring to approximately 2.5 feet above the top of the well screen
Monitoring Well Installation and Groundwater Monitoring Report

Facilities | Environmental | Geotechnical | Materials 4
placement of hydrated bentonite chips above the sand pack to the surface
placement of a locking cap at the end of the PVC
The well was completed with a well cover inset in a flush-mounted concrete well pad when
the surrounding concrete ramp was installed in December 2024. Prior to the ramp being
installed, a removable 10-foot PVC riser had been attached to the well and was being
protected by a larger diameter PVC pipe.
After installation, the well was developed using a surge block and bailer. Approximately 5
gallons of water (approximately 6 purge volumes) was purged from the well after surging,
with the water becoming progressively clearer.
The limited soil cuttings generated during drilling were thinly spread across the ground in
the vicinity of the monitoring well. Purge water generated during development activities was
spread on-site and allowed to infiltrate into the ground.
3.0 Groundwater Sampling Event
The second sampling event was conducted on January 28, 2025. Terracon gauged the depth
to water and collected a groundwater sample from the on-site monitoring well (MW-A;
Exhibit 2 (Appendix A).
Prior to collecting the groundwater sample, the well was purged using a single-use
disposable plastic bailer and twine which was discarded after use. The water meter used for
depth to water measurements was decontaminated using an Alconox wash followed by a
rinsing with potable and distilled water. The well was purged with a minimum of three well
volumes (2.64 gallons, calculated volume of water within the initial water column) extracted
prior to sampling. No sheen or distinct odor was noted during the purging or sampling.
Purge water was thin spread across the surface of the site and allowed to evaporate or
infiltrate into surface soils. Care was taken to not allow purge water to affect nearby
receptors (stormwater catch basins, utilities, etc.).
3.1 General Observations
Depth-to-water measurements are presented in Table 1 (Appendix B). Free product was not
observed during this sampling event.
4.0 Laboratory Analytical Methods
The groundwater sample was collected and placed in laboratory-prepared containers,
labeled, placed on ice in a cooler, and transported to Chemtech-Ford Laboratories in Sandy,
Utah. The groundwater sample was submitted for analysis of Total Petroleum Hydrocarbons

(TPH) Gasoline Range Organics (GRO) using United States Environmental Protection Agency
(EPA) Method 8260B, TPH Diesel Range Organics (DRO) using EPA Method 8015C, and
methyl tert-butyl ether, benzene, toluene, ethylbenzene, xylenes, and naphthalene
(MBTEXN) using EPA Method 8260D. The executed chain-of-custody form and laboratory
data sheets are provided in Appendix D.
5.0 Data Evaluation
Results of the groundwater sampling event are summarized in Table 1 (Appendix B). The
sample location is shown on Exhibit 2 (Appendix A). As presented in Table 1, all analytes
were not-detected above the reported detection limit (RDL).
5.1 Quality Control
Quality control for the sampling program was provided by using standardized sample
collection and handling methods, documenting pertinent field information, and keeping
chain-of-custody records, as well as using a Utah-certified laboratory. All sampling
procedures followed Terracon’s Standard Operating Procedures and industry practices, and
the sample was collected by a Utah-certified Soil and Groundwater Sampler.
A review of the field procedures indicates that standard operating procedures were followed
with regards to sample collection, handling, and documentation. The analytical laboratory
report indicated that samples were extracted and analyzed within appropriate sample
holding times. Internal laboratory QA/QC procedures and results are presented in the
laboratory report and were within acceptable limits set by the laboratory, except where
noted.
6.0 Findings And Conclusions
The groundwater sample did not report petroleum hydrocarbons above the laboratory RDLs
for all analytes. Hence, results were also below the ISLs. This is the second consecutive
round of groundwater monitoring that indicates the absence of these analytes above
regulatory screening levels. Closure of this release site is requested.

Re: Post Remediation Groundwater Monitoring
Former Murray Fleet, located at 4400 South Main Street, Murray, Utah
Facility Identification No. 4000598, Release Site NCD
Dear Ms. Miller:
On September 16, 2024, the Division of Environmental Response and Remediation (DERR)
received a Corrective Action Implementation Report for the above-referenced Site. After reviewing
this information, the DERR project manager has recommended further investigation to determine
the full extent of subsurface contamination.
The Corrective Action Plan for this site was approved by the DERR on August 1, 2023 and
remedial activities were carried out from August 16, 2024 through August 27, 2024. This included
the excavation and removal of 225 tons of contaminated soil and the treatment of groundwater.
Groundwater was treated by adding a 35% hydrogen peroxide solution and ferrous sulfate to the
bottom of the soil excavation. No groundwater samples were collected as part of the Corrective
Action. However, a Limited Subsurface Investigation conducted in April 2023 indicated
groundwater contamination above Initial Screening Levels (ISLs).
Due to the presence of contaminated groundwater, the Division Director is requiring Post-
Remediation Groundwater Monitoring to evaluate the effectiveness of the Corrective Action Plan.
Groundwater monitoring should occur quarterly until two consecutive sampling events indicate the
petroleum impacts to the groundwater are below ISLs.
All environmental samples must be collected by a Utah certified groundwater and soil
sampler following sampling protocol as outlined in Utah Admin. Code R311-205. The report
associated with these requirements must be submitted to our office within 90 days from the receipt
Facility ID# 4000598
Page 2
of this letter. Environmental samples must be analyzed for gasoline and diesel using the methods
indicated in the enclosed Table of Analytical Methods for Sampling.

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

Sincerely,

Brent H. Everett, Director
Division of Environmental Response and Remediation
