1.0 INTRODUCTION
1.1 Site Description
Site Name Salt Lake City Fleet Yard
Site Location/Address 800 South 325 West, Salt Lake City, Utah
General Site Description
The site was formerly used as a Salt Lake City fleet vehicle fueling and
maintenance facility. It is currently used by the Salt Lake City Police
Department as a training facility and the Fire Department for equipment
storage.
Exhibit 1 (Appendix A) presents a topographic map of the site. Exhibit 2 is a site diagram that
indicates the approximate locations of the groundwater sampling points in relation to the
pertinent site features. Exhibit 3 is a groundwater elevation map depicting groundwater gradient
conditions at the time of field activities in March 2015.
1.2 Project Background
Corrective action was implemented at the site to address petroleum-impacted soils and
groundwater remaining in the vicinity of the former underground storage tank (UST) tank pit.
The selected approach included removal of the impacted soils for off-site disposal and removal
of impacted groundwater from the open excavation, followed by limited application of chemical
oxidation reagents to treat residual petroleum-impacted groundwater within the excavation area
prior to backfilling. IHI conducted the site work following the DERR-approved Work Plan IEQ-15.
The Petroleum-Impacted Soil Excavation Report (Terracon; November 20, 2014) documented
the implementation of the Work Plan IEQ-15 during January and February of 2014. The project
goal is to meet regulatory limits for unrestricted land use and receive a “No Further Action”
status for Release ID IEQ.
n A Work Plan (Terracon; February 26, 2015) was developed to install groundwater
monitoring wells and conduct quarterly groundwater sampling to document the
concentrations of petroleum hydrocarbons remaining in the area of the former UST basin
and dispensers, post remediation.

1.3 Scope of Work
The overall objective was to evaluate the potential presence of residual groundwater
contamination in the vicinity of the former underground storage tank (UST) basin. The scope of
work included the advancement of six borings, with the collection of one groundwater sample
from each boring, and completion of the borings as monitoring wells.
1.4 Standard of Care
Terracon’s services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same

agencies or other third parties supplying information used in the preparation of the report.
These services were performed in accordance with the scope of work agreed with you, our
client, as reflected in our proposal, and were not restricted by ASTM E1903-11.
1.5 Additional Scope Limitations
Findings, conclusions and recommendations resulting from these services are based upon
information derived from the onsite activities and other services performed under this scope of
work. Such information is subject to change over time. Certain indicators of the presence of
hazardous substances, petroleum products, or other constituents may have been latent,
inaccessible, unobservable, non-detectable or not present during these services, and we cannot
represent that the site contains no hazardous substances, toxic materials, petroleum products,
or other latent conditions beyond those identified during this investigation. Subsurface
conditions may vary from those encountered at specific borings or wells or during other surveys,
tests, assessments, investigations or exploratory services; the data, interpretations, findings,
and our recommendations are based solely upon data obtained at the time and within the scope
of these services.
1.6 Reliance
This report has been prepared for the exclusive use and reliance of the Salt Lake City
Corporation and government entities having jurisdiction over the site. Use or reliance by any
other party is prohibited without the written authorization of the Salt Lake City Corporation and
Terracon.
Reliance on the report by the client and all authorized parties will be subject to the terms,
conditions and limitations stated in the proposal, report, and Terracon’s Terms and Conditions.
The limitation of liability defined in the Terms and Conditions is the aggregate limit of Terracon’s
liability to the client and all relying parties.

2.0 LIMITED SITE INVESTIGATION
2.1 Environmental Soil Borings
Prior to drilling, the public utility location service (Blue Stakes) was notified at least 48 hours
prior to drilling as required by law. In addition, a subcontracted private utility location service
was used to identify and mark subsurface utilities in the area of each boring location.
Terracon’s soil boring and monitoring well installation activities were conducted on March 2,
2015 by Jeff Kolmel, Utah UST Groundwater and Soil Sampler (#GS-1592). The approximate
boring locations are shown on Exhibit 2 (Appendix A).
The borings were advanced using direct push drilling equipment. Mechanized drilling services
were performed by a State of Utah licensed Monitoring Well Driller using a direct push drilling rig
under the supervision of a Terracon Environmental Project Manager. Mechanized drilling
equipment was cleaned using a high pressure washer prior to beginning the project and before
beginning the soil boring. Soil samples were collected continuously from the boring using a five-
foot macro-core sampler.
Soil cores were observed to document soil types, color, moisture content and sensory evidence
of environmental impacts. The soil samples were also field-screened using a portable
photoionization detector (PID) – Mini Rae 2000 PID to determine the potential presence of total
volatile organic compounds (TVOCs). The subsurface soil types encountered during sample
collection varied between borings but generally consisted silty sands, clays, and sands. PID
readings ranging from non-detect to 71.9 parts per million (ppm). Groundwater was typically
encountered at depths of approximately 9 to 10 feet bgs. Detailed lithologic descriptions and
PID readings are presented on the soil boring logs included in Appendix B.
2.2 Monitoring Well Installation
The six borings were completed as permanent groundwater monitoring wells (T-1 through T-6)
using the following procedures:
n Installation of 10 feet of 2-inch diameter, 0.010-inch machine slotted PVC well screen
with a threaded bottom cap;
n Installation of 2-inch diameter, threaded, flush-joint PVC riser pipe to the surface;
n Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the well
screen from the bottom of the boring to approximately 2 feet above the top of the well
screen;
n Placement of 2 feet of hydrated bentonite pellets above the sand pack;
n Addition of cement/bentonite slurry to the surface; and,

Responsive ■ Resourceful ■ Reliable 4
n Installation of a 7-inch diameter, circular, bolt-down, steel, monitoring well cover with a
locking well cap inset in a flush-mount, concrete well pad.
2.3 Subsurface Soil Sampling
Since the wells were installed in areas previously excavated, soil samples were not collected
from the borings.
2.4 Groundwater Sampling
The groundwater sampling event was conducted on March 5, 2015 by Mark Lilly, Utah UST
Groundwater and Soil Sampler (#GS-449). Prior to sample collection, Terracon measured
groundwater levels in the six newly installed monitoring wells. The wells were then developed
by surging and removing groundwater until the well discharge was relatively free of fine-grained
sediment. Prior to sample collection, each well was purged of a minimum of three casing
volumes (or until the well ran dry and was allowed to recharge), using a new disposable bailer
for each well. Groundwater samples were then collected directly into the appropriate laboratory-
provided containers.
2.5 Gradient Measurement
Based on the water level measurements and top-of-casing elevation data collected March 5,
2015, the flow direction within the former UST basin was to the south, and to the southeast
outside the former UST basin. (Appendix A, Exhibit 3).
3.0 LABORATORY ANALYTICAL METHODS
The groundwater samples were collected and placed in laboratory prepared containers, labeled,
and placed on ice in a cooler. The samples and completed chain-of-custody forms were
shipped via overnight courier to Environmental Science Corporation analytical laboratory in Mt.
Juliet, Tennessee (a Utah Certified Laboratory).
The samples were analyzed by laboratory test methods as appropriate for the type(s) of
contaminants most likely to be associated with the former UST systems; methyl tert-butyl ether
(MTBE), benzene, toluene, ethylbenzene, xylenes, and naphthalene (BTEXN), total petroleum
hydrocarbons in the gasoline range (TPH-GRO), and total petroleum hydrocarbons in the diesel
range (TPH-DRO). Samples were analyzed using the following methods:

The executed chain-of-custody form and laboratory data sheets are provided in Appendix D.
4.0 DATA EVALUATION
Please refer to Table 1 (Appendix C) for a summary of the laboratory analytical results for
historic subsurface soil samples. Please refer to Table 2 (Appendix C) for a summary of the
laboratory analytical results for groundwater samples. Tables 1 and 2 also include comparative
regulatory screening levels for comparative purposes.
Petroleum hydrocarbons were reported in all six groundwater samples collected from the newly
installed monitoring wells. Monitoring wells T-3, T-4, and T-6, located south of the former UST
basin, reported concentrations that exceeded an ISL but not a Tier 1 Screening Level. The
concentration of TPH-DRO exceeded the ISL in monitoring wells T-3, T-4 and T-6. The
concentration of benzene exceeded the ISL in monitoring wells T-3 and T-6.
5.0 FINDINGS AND CONCLUSIONS
Based on the results of this groundwater sampling event, it appears that petroleum impacts to
groundwater exceeding an ISL remain south of the former UST basin. The extent of the impacts
has not been defined.
