1.0 Introduction
Corrective action was required at the Former Murray Fleet facility to address petroleum-
impacted soils remaining on the site originating from a release from an underground
petroleum storage tank owned by Lumen Technologies, Inc. (Lumen). Terracon developed a
Corrective Action Plan (CAP), dated May 17, 2023, which was approved by the Utah
Department of Environmental Quality (UDEQ) Division of Environmental Response and
Remediation (DERR).
The CAP was designed to address removal of the impacted soils and facilitate re-
development of the site for the new property owner.
1.1 Site Description
Site Name Former Murray Fleet Facility
Site Location/Address 4400 South Main Street, Murray, Utah
General Site
Description
The entire site is approximately 1.94 acres occupying one
parcel. The building covering the impacted soil area was
demolished during the time of the remedial action.
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 approximate locations of the
historical and recent soil borings and related features.
1.2 Project Information
The former Murray Fleet Facility site is located at 4400 South Main Street in Murray, Utah.
The facility had previously been operated by US WEST, Qwest Communications, and
CenturyLink (now Lumen) and included offices, fleet maintenance facilities, service vehicles,
and support equipment. The property is now owned by Evergreen—45th & Main Land, LLC.
and was most recently used to store recreational vehicles.
Two petroleum underground storage tank (UST) releases were reported to the UDEQ DERR
and 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. 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 the early 1990s to the middle 2010s.
A corrective action remediation was performed in 2013 with removal of impacted subsurface
soils, and post-remediation reports detailing this work in both areas were submitted to
Corrective Action Implementation Report
Former Murray Fleet Facility | Murray, Utah
September 16, 2024 | Terracon Project No. 61237057
Facilities |Environmental | Geotechnical | Materials 2
DERR. Release HDA received regulatory “No Further Action” status from the DERR in March
2014, and the northern portion of the site has since been redeveloped for multifamily
residential use.
A portion of the impacted soils related to Release NCD could not be removed and was left in
place below the western portion of the facility’s maintenance building. DERR agreed to wait
until the on-site building located above a portion of Release NCD was demolished prior to
requiring further remedial action in that area.
In 2022, the current property owner notified DERR of a planned demolition of the building.
As a result, DERR sent a letter dated May 26, 2022 to Lumen, the responsible party, stating
that a CAP will need to be developed in order to properly remediate the remaining
contamination related to Release NCD (Appendix B).
Terracon prepared a CAP intended to meet the criteria and standards established by DERR
in order for the remediation to protect human health and the environment, be cost effective,
and use the appropriate cleanup technology.
1.3 Objective
The objective of the CAP was to remove the petroleum-impacted soils and treat
groundwater remaining beneath the former on-site building adjacent to the former UST
basin that exceeded regulatory screening levels.
1.4 Extent of Contamination
A subsurface investigation conducted on the property by Wasatch Environmental in 2022
collected soil and groundwater samples on the property. Soil borings were specifically drilled
in the former UST area. The results of the investigation (report dated May 16, 2022)
reported petroleum hydrocarbons in soil that exceeded DERR Initial Screening Levels (ISLs)
and groundwater that exceeded DERR ISLs and Tier 1 Screening Levels for petroleum
hydrocarbons in one location. Volatile organic compounds (VOCs) were not reported to
exceed a regulatory screening level in the soil or groundwater samples.
A Limited Site Investigation (LSI) conducted by Terracon (Terracon, April 26, 2023)
identified a small area within the on-site building and adjacent to the former used oil UST
(Release NCD) where soil and groundwater contamination was previously identified. The
Terracon LSI included five soil borings for the collection of soil and groundwater samples.
Historic and current Terracon boring locations are shown on Exhibit 2 (Appendix A).
One soil sample (B-4-8) collected at eight feet below the ground surface (bgs) exceeded the
UDEQ ISL for Total Petroleum Hydrocarbons (TPH)—Diesel Range Organics (DRO). While
other analytes were detected above the laboratory Reported Detection Limit (RDL), this was
the only sample to exceed a UDEQ screening level. VOCs were not reported to exceed a
regulatory screening level.

Former Murray Fleet Facility | Murray, Utah
September 16, 2024 | Terracon Project No. 61237057
Facilities |Environmental | Geotechnical | Materials 3
Groundwater was encountered at approximately eight feet bgs in each of the borings.
Groundwater from boring B-2 exceeded UDEQ ISLs for TPH – Gasoline Range Organics
(GRO) and benzene, and groundwater from boring B-4 exceeded UDEQ ISLs for TPH-DRO
and TPH-GRO. Vapor Intrusion Screening Levels (VISLs) for ethylbenzene, naphthalene,
and/or xylenes were exceeded from groundwater samples collected from borings B-2, B-3,
and B-4. Based on the results of the LSI, the approximate extent of soil contamination
remaining above a screening level encompassed approximately 300 square feet adjacent to
the historical tank. The contaminated soil in the area extended from a minimum of five feet
bgs to a depth of at least eight feet bgs but not below twelve feet bgs (where a clean soil
sample was collected).
1.5 Public Notice
Upon receipt of DERR approval of the CAP, the potentially affected public was notified of the
remedial action. On June 22, 2023, the public notice was posted at the property and hand-
delivered to the adjoining properties where public comment was solicited. A copy of the
Public Notice is included in Appendix B. No comments were received.
2.0 Methodology
The proposed corrective action methodology was to excavate and remove impacted soils
remaining at the site associated with Release ID NCD and remove (if required for
excavation) and treat impacted groundwater during excavation.
Prior to excavation work, the public utility location service (Blue Stakes) was be notified at
least 48 hours prior to digging or drilling as required by law. In addition, a subcontracted
private utility location service was used to identify and mark subsurface utilities around the
planned excavation area.
2.1 Soil Excavation and Disposal
Soil excavation and transportation services were contracted to Direct Push Services (Direct
Push). Soil excavation activities began on August 16, 2024, and were completed on August
23, 2024. Backfilling and compaction continued at the site until August 27, 2024.
Soil was excavated in the defined area (Appendix A Exhibit 3) to depths ranging from
approximately twelve to thirteen feet bgs. The entire excavation area measured
approximately 16 feet (east–west) by 29 feet (north–south). Unimpacted soils (based on
previous investigations, PID readings, and visual observations) from the surface to
approximately seven feet bgs were excavated and set aside. This soil was later reused by
the site for ground leveling, topsoil, and general site improvement activities.

September 16, 2024 | Terracon Project No. 61237057
Facilities |Environmental | Geotechnical | Materials 4
The impacted soils were transported to and disposed of at ET Technologies Soil
Regeneration Site in Salt Lake City (ET Technologies). Characterization sampling of the
impacted soil was conducted per ET Technologies requirements. Results of the profile
sample are included in Table 1 (Appendix C).
Approximately 255 tons of petroleum-impacted soils were transported to ET under proper
waste manifest. A copy of the weight tickets is included in Appendix E.
2.2 Confirmation Soil Sampling
Upon completion of the soil excavation, a confirmation soil sample was collected from each
of the four sidewalls and one from the floor of the excavation. Samples were collected at a
specific depth based on visual observations and field screening using a PID. Sample
locations are shown on Exhibit 3 (Appendix A) and results are shown on Table 1 (Appendix
C).
The confirmation soil samples were submitted to Chemtech-Ford Laboratories in Sandy,
Utah, for analysis of TPH-DRO, TPH-GRO, Total Recoverable Petroleum Hydrocarbons
(TRPH), and methyl tert-butyl ether, benzene, toluene, ethylbenzene, xylenes, and
naphthalene (MBTEXN). A copy of the laboratory analytical reports is included in Appendix
D.
2.3 Groundwater Management
Dewatering was not required during excavation. A frac tank to be used for storing and
sparging groundwater was available on-site as needed. However only a minimal amount of
water entered the excavation, so groundwater pumping and sparging was not necessary.
2.4 Groundwater Treatment—Hydrogen Peroxide Application
In order to reduce residual soil and groundwater impacts in the immediate vicinity of the
excavation, a chemical oxidation event using hydrogen peroxide and ferrous sulfate was
implemented after excavation of impacted soils. The amount of hydrogen peroxide and
ferrous sulfate used was based on supplier recommendations and professional judgement.
One 55-gallon drum containing a 35% solution of hydrogen peroxide was added directly into
the groundwater at the bottom of the excavation via the use of a pump and hose. Specific
areas were targeted based on where residual contamination appeared most likely to remain.
After hydrogen peroxide application, 10 pounds of ferrous sulfate was added into the
excavation to further advance the chemical reaction.

2.5 Backfill and Surface Restoration
The excavation was backfilled with clean imported gravel, with the gravel placed in
approximately eight to twelve inch lifts and properly compacted to approximately 95%
compaction rate. A geotextile fabric was placed on top of the gravel at approximately eight
feet bgs. Engineered road base was installed as needed and properly compacted from
approximately one foot bgs to the surface. Stockpiled overburden from the top seven feet
was not mixed with the gravel backfill and was only used at the very top for ground
leveling. The surface was completed to match the surrounding area based on the site
owner’s request.
2.6 Sampling Quality Control/Quality Assurance
All oversight and sampling work during the excavation and groundwater treatment was
conducted under the direction of a Utah-Certified UST Consultant. All environmental
samples were collected by a Utah-Certified Groundwater and Soil Sampler. Quality
assurance for the sampling program included standardized sample collection, preservation,
and handling methods as well as documenting field information and keeping chain-of-
custody records. Samples were analyzed by Chemtech-Ford Laboratories, a Utah-certified
laboratory.
3.0 Conclusion
The corrective action implemented at the site successfully removed impacted soils
exceeding a regulatory screening level. The source of groundwater impacts was removed
from the area, and the treatment applied to the excavation after the removal of impacted
soils will further enhance degradation of any remaining petroleum hydrocarbons in the
groundwater.

Petroleum Release Cleanup Project
Former Murray Fleet Facility, Release ID NCD
4400 South Main Street, Murray, Utah
A historic release of petroleum hydrocarbons was reported at the former Murray Fleet Facility
located at 4400 South Main Street, Murray, Utah. The current property owner intends to
redevelop the site. As petroleum-impacted soils and groundwater exceeding a regulatory
screening level associated with a previously removed historic underground storage tank remain
at the site, the owner would like to remove and properly dispose of the impacted soils to allow
for unrestricted development of the property. A Utah Department of Environmental Quality
(UDEQ), Division of Environmental Response and Remediation (DERR) approved Corrective
Action Plan was developed to address the removal of impacted soils and groundwater.
Site Description
The facility had previously been operated by US WEST, Qwest Communications, and CenturyLink
and included offices, fleet maintenance facilities, service vehicles, and support equipment. Two
underground storage tank (UST) releases reported to the DERR were identified at the facility.
One of the releases involved a former gasoline and diesel fuel UST area (Release HDA) 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. Both releases were remediated in 2013 with removal of impacted subsurface soils.
However, 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 maintenance building. That building is now
scheduled for demolition and the soils can be accessed.
Cleanup Measures
The proposed cleanup approach is to excavate and remove petroleum-impacted soils above the
DERR Initial Screening Level from the site. A hydrogen peroxide and ferrous sulfate solution will
then be applied to the groundwater remaining in the excavation prior to backfill with clean soil.
Schedule
On-site cleanup activities are anticipated to begin in August 2023. Once started, the corrective
actions are expected to take approximately 8 to 10 weeks to complete.
For More Information
A copy of the Corrective Action Plan prepared for this site is available at the DERR in Salt Lake
City (address below; office hours 8:00 a.m. to 5:00 p.m., Monday through Friday). For additional
