1.0 INTRODUCTION
Terracon Consultants, Inc. (Terracon) has completed a supplemental Phase II Environmental Site
Assessment (Site Investigation) at the Lelis Transmissions site located at 845 South Main Street
in Salt Lake City, Utah (Exhibit 1; Appendix A). The site is identified in EPA’s online Assessment,
Cleanup and Redevelopment Exchange System (ACRES) as Property ID# 237101.
In 2019, Terracon conducted a Phase I Environmental Site Assessment (Phase I ESA; July 25,
2019) on the site as part of the Salt Lake County Brownfields Assessment Grant with funding from
the Salt Lake County Brownfields Assessment Grant, EPA Cooperative Agreement No.
96835701. The property was approved for assessment by EPA under a Site Eligibility
Determination Outline (EPA Region 8, April 4, 2018), designated as hazardous substances
commingled with petroleum. A subsequent Phase II Site Investigation (Phase II Environmental
Site Assessment; September 30, 2019) was completed following an approved Sampling and
Analysis Plan (SAP; August 19, 2019). Based on the impacts identified in the Phase II ESA,
Terracon prepared a Remedial Alternatives Evaluation (July 20, 2020) to support redevelopment
of the site by prospective developers by providing preliminary cleanup planning information. The
Remedial Alternatives Evaluation identified the need for additional data pertaining to impacted
soils and groundwater at the site.
This Phase II Site Investigation was designed to collect the additional site information identified
in the Remedial Alternatives Evaluation and was completed with funding from the Salt Lake
County Brownfields Assessment Grant EPA Cooperative Agreement No. 96896101.
1.1 Brownfields Setting
Salt Lake County (the Grantee) is a recipient of an EPA community-wide assessment grant to
inventory, characterize, assess, and conduct cleanup planning along with public outreach
activities for eligible Brownfield sites located within County boundaries.
Terracon prepared a Remedial Alternatives Evaluation (July 20, 2020) to evaluate options to
remediate impacts reported at the site. The Remedial Alternatives Evaluation identified the need
for additional data pertaining to soils and groundwater at the site. As part of the Brownfields Grant,
this Phase II Site Investigation was conducted to gather the information necessary to further
Phase II Environmental Site Assessment

define and evaluate impacts identified at the site. Site work was guided by a Sampling and
Analysis Plan (SAP) reviewed, amended and approved by EPA (September 2, 2020). Quality of
assessment data was guided by the SAP and EPA-approved Community-Wide Quality Assurance
Project Plan Salt Lake Brownfields Coalition Assessments (Terracon, January 21, 2020).
1.2 Site Description
The site is located at 845 South Main Street, Salt Lake City, Utah and is occupied by the Lelis
Transmissions shop. The property is used as an auto repair facility. Commercial improvements
at the site include an L-shaped 1-story building with mezzanine and approximately 7,400 square-
foot automotive service/repair facility. The office/warehouse was used for storage of automotive
parts and reference materials, the eastern part of the building is used for conducting automotive
repair. The Lelis Transmissions site is identified as Salt Lake County Parcel ID 16-07-151-010
and in EPA’s online Assessment, Cleanup and Redevelopment Exchange System (ACRES) as
Number 237101.
1.3 Previous Investigations
A Phase I ESA and two Phase II ESAs have been performed on the site located at 845 South
Main Street, Salt Lake City, Utah, occupied by the Lelis Transmissions shop.
Terracon had previously conducted a Limited Site Investigation (LSI) on the site in 2015 to
evaluate the source of diesel contamination reported on the south-adjoining property. Soil and
groundwater samples were collected in the vicinity of the former gasoline underground storage
tank (UST) that was removed from the Lelis Transmissions site in 1991. Diesel-range and
gasoline-range petroleum hydrocarbons were reported in soils and groundwater above the Utah
Department of Environmental Quality (UDEQ) Screening Levels on the Lelis site, but at
concentrations less than those reported present on the south-adjoining property. The observed
distribution and type of contaminant reported on the Lelis site was determined to likely have
originated from an off-site source. A copy of the 2015 LSI report including the boring locations
and analytical results of soil and groundwater samples is included in Appendix E.
Suspect site features identified during the Phase I ESA are shown on Exhibit 2 (Appendix A).
Boring locations installed during the 2019 Phase II Environmental Site Assessment are shown on
Exhibits 3 and 4. Analytical results of the soil, groundwater and soil gas samples collected at the
site were compared to the EPA Regional Screening Levels (RSLs), Vapor Intrusion Screening
Levels (VISLs) and Maximum Contaminant Levels for tapwater, as well as UDEQ Initial Screening
Levels (ISLs) and Tier 1 Screening Levels (Tier 1) for petroleum hydrocarbons in soil and
groundwater. A copy of the Data Summary Tables from the 2019 Phase II ESA is included in
Appendix E. The following impacts were identified on the property through the course of the Phase
II ESAs and the 2015 LSI:

1.3.1 Soil Impacts
n Widespread soil impacts were identified by petroleum hydrocarbons, primarily in the form
of total recoverable petroleum hydrocarbons (TRPH) and total petroleum hydrocarbons in
the diesel-range (TPH-DRO). Exhibit 5 (Appendix A) displays the boring locations and
results of the 2019 soil sampling event.
§ A total of eight soil sampling locations identified TRPH concentrations
exceeding the ISL of 1,000 milligrams per kilogram (mg/kg), and four
sampling locations identified TRPH concentrations above the Tier 1
Screening Level of 10,000 mg/kg.
§ A total of nine soil sampling locations identified TPH-DRO concentrations
exceeding the ISL of 500 mg/kg, and three sampling locations identified
TPH-DRO concentrations above the Tier 1 Screening Level of 5,000
mg/kg.
§ Four soil sampling locations identified total recoverable petroleum
hydrocarbons in the gasoline range (TPH-GRO) concentrations above the
ISL of 150 mg/kg; three of these locations were adjacent to the former on-
site gasoline UST.
§ None of the soil samples identified individual Utah-regulated petroleum
hydrocarbon compounds [benzene, toluene, ethylbenzene, toluene,
naphthalene (BTEXN) and methyl-tert-butyl ether (MTBE)] at
concentrations above ISLs or Tier 1 Screening Levels. One soil sample
reported a naphthalene concentration above the residential RSL of 3.8
mg/kg, but below the industrial RSL of 17 mg/kg and below the ISL and
Tier 1 Screening Level of 51 mg/kg.
n Soil impacts by volatile organic compounds (VOCs) were not identified, other than one
soil sample with a reported naphthalene concentration above the residential RSL but
below all other Screening Levels.
n A total of ten (10) soil samples collected from five (5) soil borings were analyzed for the
13 Priority Pollutant Metals. All soil samples reported arsenic concentrations above the
EPA Industrial RSL. However, such exceedances are common throughout the Salt Lake
Valley area where background values reportedly range from non-detect to 97 mg/kg (U.S.
Geological Survey Professional Paper 1270; 1984). The arsenic concentrations reported
in site soil samples ranged from 4.02 to 41.1 mg/kg. Based on these results, the reported
arsenic concentrations in soil appear to be representative of natural background levels.
n The concentration of lead reported at one soil boring (LT-B-15, near the oil/water
separator) exceeded the EPA Industrial RSL. This same boring also reported the above-
referenced naphthalene exceedance of the residential RSL.

1.3.2 Groundwater Impacts
n Free product was observed within the soil profile at two boring locations in the eastern and
central portions of the site. The observed product exhibited a viscous oily appearance
and did not appear to be associated with diesel fuel or gasoline. Exhibit 6 (Appendix A)
displays the boring locations and results of the groundwater sampling event and Exhibit 7
displays the groundwater gradient.
n Widespread groundwater impacts were identified by petroleum hydrocarbons, primarily in
the form of TRPH and TPH-DRO. A localized occurrence of TPH-GRO was also identified
during the 2015 LSI.
§ Two groundwater sampling locations identified TRPH concentrations
exceeding the Tier 1 Screening Level of 10 milligrams per liter (mg/l).
§ A total of three groundwater sampling locations identified TPH-DRO
concentrations exceeding the ISL of 1 mg/l, and four sampling locations
identified TPH-DRO concentrations above the Tier 1 Screening Level of 10
mg/l.
§ One groundwater sampling location identified a TPH-GRO concentration
above the ISL of 1 mg/l, adjacent to the former onsite gasoline UST.
§ None of the groundwater samples identified any BTEXN or MTBE
constituent concentrations above ISLs or Tier 1 Screening Levels.
n Groundwater impacts by VOCs were not identified above Screening Levels, other than
two samples that reported concentrations of a VOC that were higher than the
corresponding groundwater VISL. Trichloroethene and 1,4 Dichlorobenzene
exceeded the Residential VISL, and naphthalene exceeded the Industrial VISL.
n Two groundwater samples identified dissolved arsenic at a concentration above the
MCL, and one of these also exceeded the Utah Ground Water Protection Standard
(UGWPS).
n The 2019 Phase II ESA included the completion of four of the borings as temporary
piezometers to allow evaluation of the local groundwater flow conditions. Based on
groundwater elevation measurements from the piezometers, the groundwater flow
direction is to the northwest.
1.3.3 Soil Gas
Sub-slab soil gas sample points were installed four locations throughout the site (Exhibit 4;
Appendix A). Multiple VOCs were detected at concentrations above the laboratory method
detection limits, but at concentrations below the corresponding residential and commercial VISLs.
Although two of the groundwater samples reported concentrations of a VOC (Trichloroethene and
1,4 Dichlorobenzene exceeded the Residential VISL, and naphthalene exceeded the Industrial

VISL) that were higher than the corresponding groundwater VISL, the sub-slab soil vapor sample
results did not indicate a potential vapor intrusion issue.
1.3.4 Remedial Alternatives Evaluation
Terracon’s Remedial Alternatives Evaluation was developed with the understanding that the
current owner seeks to perform sufficient cleanup to sell the property for redevelopment while
retaining the existing buildings. The buildings would be incorporated into a future re-development
for commercial/industrial use and could potentially include residential use.
Based on the proposed redevelopment plan and land use, five remedial alternatives were
evaluated:
n Alternative 1: No Action
n Alternative 2: Remove Contaminant Source Structures
n Alternative 3: Mobile Dual-Phase Extraction (MDPE)
n Alternative 4: Remove Impacted Soils
n Alternative 5: TPH Fractionation and Development of site-specific cleanup Levels (SSCLs)
A multiple-component approach involving Alternatives 2, 3, and 5 was recommended. With this
approach, ongoing and/or future contaminant releases are prevented by removing the primary
contaminant sources (Alternative 2), and targeted free product removal (Alternative 3) eliminates
the remaining onsite source of groundwater contamination. Petroleum impacts to soil and
groundwater are addressed through TPH fractionation and development of SSCLs, and remaining
impacts are managed in place with appropriate controls such that no complete exposure
pathways exist. The lead impacts will be addressed during the remediation effort with the removal
of the oil/water separator and limited removal of impacted soils.

2.0 PHASE II SITE INVESTIGATION
2.1 Scope
This Phase II scope of work addresses the collection of soil and groundwater samples for further
delineation of impacts and for analyses at critical locations using Total Petroleum Hydrocarbon
(TPH) Fractionation. The TPH Fractionation results are evaluated using the Utah Department of
Environmental Quality (UDEQ); Division of Environmental Response and Remediation (DERR)
Site-Specific Cleanup Level (SSCL) Calculator V1.2 (2015.10.22).
These activities were conducted in accordance with a site-specific SAP that was prepared and
approved by EPA for this site. The SAP established specific site objectives, sampling process
design, and details regarding site-specific sampling and analyses, and was used in conjunction
with the EPA-approved QAPP.
2.2 Sampling Process Design
Six (6) soil borings were advanced using direct-push drilling equipment to allow for the collection
of subsurface soil and groundwater samples.
To further characterize soil impacts using TPH Fractionation, three (3) borings were advanced in
the vicinity of the previous boring locations that reported the highest impacts in the 2019 Phase II
investigation, and one (1) boring was advanced adjacent to a previous boring that reported the
highest TPH-GRO impact in groundwater in the 2015 LSI. Exhibit 8 (Appendix A) shows the
locations of the soil borings.

n Boring LT-B-2: one soil sample collected from the interval reporting the
highest impacts: 9 feet below grade surface (bgs).
n Boring LT-B-5: one soil sample collected from the interval reporting the
highest impacts: 8 feet bgs.
n Boring LT-B-7: one soil sample collected from the interval reporting the
highest impacts: 7.5 feet bgs.
n Boring LT-B-19: one soil sample collected from the interval reporting the
highest impacts: 10 feet bgs.
n One groundwater sample was collected from each boring.
Two (2) borings were advanced to further delineate the extent of impacted soils and groundwater:
LT-B-17 and LT-B-18.
n One soil sample was collected from each boring at the obvious zone
exhibiting signs of impacts or at the capillary fringe if impacts not identified in
the field.
n One groundwater sample was collected from each boring.
The soil borings were advanced to a maximum depth of approximately 15 feet bgs to allow for
sufficient water to collect groundwater samples. After sample collection was completed, each
boring was properly abandoned by backfilling with bentonite clay pellets, adding water to hydrate
the bentonite clay, and restoring the surface with native soil, asphalt, or concrete patch as
appropriate to match the surrounding area. Samples were delivered to the analytical laboratory
within holding times for all analytical methods to generate definitive analytical data, which are
critical to this assessment.
Table 1 below provides a summary description of the sample locations, sample types, sample
naming convention, laboratory analyses, and sampling rationale.

2.3 Field Data Collection
Following SAP approval, the public utility location service (Blue Stakes of Utah) was notified at
least 48 hours prior to commencing drilling activities. A private utility location service was used
to locate potential utilities and other subsurface obstacles in the immediate vicinity of each boring
location.
Terracon conducted the field investigation on September 11, 2020. The mechanized drilling
services were performed by Utah-licensed well driller Direct Push Services; Terracon

Terracon Project 61197491 Task 34 ■November 18, 2020
Responsive ■Resourceful ■Reliable 9
environmental personnel directed and supervised the drilling activities, logged the soil borings,
and collected field samples.
During advancement of the soil borings, soils were continuously cored in 5-foot intervals and
observed to document subsurface soil types, color, relative moisture content, and sensory
evidence of environmental impacts. The soil samples were field-screened using a portable
photoionization detector (PID) – Mini Rae 3000 PID equipped with a 10.6 eV ultraviolet lamp to
evaluate the potential presence of total volatile organic compounds (TVOCs). The unit measures
TVOCs in sample headspace air relative to parts per million calibration gas equivalents in air and
identified simply as “PPM” on soil boring logs.
Native soils consisted of silts, silty clay, and sand. Elevated PID readings, with stained soils and
odors were identified in the field. Detailed lithological descriptions and PID readings are included
on the soil boring logs provided in Appendix B. Groundwater was encountered between
approximately 9 to 11 feet bgs during boring installation with a calculated gradient to the
northwest.
2.4 Soil Sampling
Soil samples were collected from each of the six (6) direct-push borings following the procedures
detailed in Standard Operating Procedure (SOP) 5, Geoprobe Sampling, which is provided in
Appendix B of the EPA-approved QAPP. During advancement of the borings, soils were logged
as detailed in SOP 1, Soil Sampling and Logging, provided in Appendix B of the EPA-approved
QAPP.
One soil sample was collected from each boring from the specified soil interval or the soil interval
exhibiting the highest elevated PID readings. If no elevated PID reading was observed, one
sample was collected from the interval most likely to contain environmental impacts as determined
in the field by the sampling professional.
2.5 Groundwater Sampling
Groundwater samples were collected from each of the six (6) of the direct-push borings following
the procedures detailed in SOP 5, Geoprobe Sampling, provided in Appendix B of the EPA-
approved QAPP.
2.6 Field QA/QC Samples
Per the QAPP, field duplicate samples for soil and groundwater were collected at a minimum rate
of 10 percent. A total of six (6) soil samples and six (6) groundwater samples were collected. For
this investigation, two field duplicate soil and two field duplicate groundwater samples were
collected, which represents a duplicate frequency of 33% per sample media. One duplicate
Phase II Environmental Site Assessment

sample was analyzed for each laboratory analytical method, which represents the following
duplicate frequencies per analytical method.
n TPH-GRO, TPH-DRO, TRPH, and total lead in soil:1 duplicate for 3 samples or
33.3%
n PCBs in soil: 1 duplicate for 2 samples or 50%
n TPH-GRO, TPH-DRO, TRPH, and total lead in groundwater: 1 duplicate for 2
samples or 50%
n PCBs in groundwater: 1 duplicate for 2 samples or 50%
n TPH-GRO Fractionation in soil: 0 duplicates for 1 sample or 0%
n TPH-DRO Fractionation in soil: 1 duplicate for 3 samples or 33.3%
n TPH-GRO Fractionation in groundwater: 0 duplicates for 1 sample or 0%
n TPH-DRO Fractionation in groundwater: 1 duplicate for 3 samples or 33.3%
The duplicates were given a fictitious identification so that the laboratory would be unaware of
their duplicate status.
The two soil borings selected for duplicate soil sampling were LT-B-2A @ 9.5’ (duplicate sample
ID LT-B-22 @ 9.5’) and LT-B-17 @ 10’ (duplicate sample ID LT-B-37 @ 10’). The two groundwater
duplicate samples were collected from boring LT-B-2A GW (duplicate sample ID LT-B-22 GW)
and LT-B-17 GW (duplicate sample ID LT-B-37 GW).
Three trip blanks (laboratory supplied blank) were included in the shipments.
2.7 Equipment Decontamination
Non-expendable sampling equipment was decontaminated at the beginning of the project and
decontaminated between each sampling location. These items were hand-scrubbed in an
Alconoxä and potable water solution and rinsed with potable water between sample locations.
Drilling equipment was cleaned using a high-pressure washer prior to beginning the project and
between boring locations.
2.8 Site Restoration
After sample collection was completed, each boring was properly abandoned by backfilling with
bentonite clay pellets, adding water to hydrate the bentonite clay, and restoring the surface with
existing soil, asphalt, or concrete patch as appropriate to match the surrounding area.
3.0 LABORATORY ANALYTICAL METHODS
All soil and groundwater samples (including field duplicates and trip blank) were placed in iced
coolers. The samples were shipped in iced coolers under chain-of-custody protocols via overnight
courier to Pace Analytical Laboratories in Mt. Juliet, Tennessee (a Utah-Certified laboratory). Soil

Underground Storage Tank (LUST) Initial Screening Levels (ISLs) and Tier 1 Screening Levels.
Primary constituent concentrations in groundwater were compared to EPA Maximum
Contaminant Levels (MCLs), EPA VISLs, UDEQ-LUST ISLs and Tier 1 Screening Levels.
The TPH fractionation analyses are based on EPA Methods 8260 and 8270 and are designed to
identify hydrocarbon fraction ranges from C5-C6 aliphatic hydrocarbons to C22-C35 aliphatics in
addition to specific associated VOCs and semi-volatile compounds. The maximum values from
the fractionation analyses and primary constituent analyses were entered into the DERR SSCL

calculator, along with the appropriate site-specific input parameters. Overall, the fractionation
results appear to be consistent with residual “heavy-end” or large carbon chain petroleum
associated primarily with diesel and oils (including hydraulic oil). The calculator was run twice
(once assuming commercial land use, and once with residential land use assumptions). For an
overview of the fractionation results, please refer to the SSCL calculator output (Appendix C),
which includes the maximum reported concentrations in each of the various C-ranges. The
calculator requires a data entry for each chemical to be evaluated, and where analytical sample
results were below the laboratory reporting limit (“non-detect”) the laboratory reporting limit value
is entered into the calculator.
4.1 Soil Data Analyses
Petroleum Hydrocarbons: The concentrations of petroleum hydrocarbons reported in the
delineation of impacts borings B-17 and B-18 reported concentrations of TPH-DRO and TRPH to
exceed the UDEQ ISL. Boring B-17 additionally exceeded the ISL for TPH-GRO. Exhibit 9
(Appendix A) displays a summary of the soil sample results exceeding a UDEQ Screening level.
Lead: Total lead was analyzed in soil in borings B-17, -18, and -19 to delineate lead impacts
reported in boring B-15. Lead was not reported at a concentration that exceeded the EPA
residential RSL.
PCBs: Soil samples collected from boring B-7A did not report concentrations of PCBs that
exceeded the laboratory detection limit. The soil sample collected from boring B-2A reported a
low concentration of PCB 1254: the concentration reported was below the EPA residential RSL.
4.2 Groundwater Data Analyses
Petroleum Hydrocarbons: The concentrations of petroleum hydrocarbons reported in the
delineation of impacts borings B-17 and B-18 reported concentrations of TPH-DRO that exceeded
the UDEQ Tier 1 Screening level. Exhibit 10 (Appendix A) displays a summary of the groundwater
sample results exceeding a UDEQ Screening level.
PCBs: Groundwater samples collected from borings B-2A and B-7A did not report concentrations
of PCBs that exceeded the laboratory detection limit.
4.3 TPH-Fractionation Analyses
The maximum concentrations from the available site data were entered into the SSCL calculator
for the various C-ranges and associated VOCs and semi-volatile compounds identified in soil and
groundwater samples. A copy of the SSLC Calculator is included in Appendix C.2. In cases where
the highest concentrations were below the laboratory reporting limit, the reporting limit was
entered as required by the SSCL calculator. Although the SSCL calculator does not have entry
cells available for measured sub-slab vapor concentrations, it does have entry cells for

concentrations in (indoor) air. Therefore, to allow a valid comparison of the sub-slab vapor
concentrations with the calculated SSCL values for air, the measured sub-slab concentrations
from the 2019 Phase II ESA were entered after conversion to estimated indoor air concentrations
by applying a slab attenuation factor of 0.03 (33.33), consistent with DERR and EPA OSWER
guidance. The data entries were identical for each of the two SSLC calculator runs, with only the
land use assumption (commercial and residential) changed between the two runs.
Using the commercial land use assumption, the output from the SSCL calculator showed no
exceedances of SSCLs for any of the C-ranges or constituents that were detected, with one
apparent exception. For aliphatics (C7-C8), the SSCL calculator indicates an apparent
exceedance of the subsurface soil SSCL for the indoor air vapor inhalation pathway. Although
the previous sub-slab vapor samples did not include fractionation analysis (so a directly measured
vapor value for C7-C8 aliphatics is not available), the designated surrogate compound for this C-
range (heptane) was analyzed in the vapor samples, and entry of its maximum measured value
did not indicate exceedance of the SSCL for air (vapor). Additionally, the maximum concentration
of C7-C-8 aliphatics in groundwater was well below the groundwater SSCL for the indoor air vapor
inhalation pathway. For several PAH compounds that were not detected in the soil and
groundwater samples, the SSCL calculator indicated apparent exceedances of SSCLs, but these
were artifacts of the calculator’s algorithms. The SSCL calculator requires input of the detection
limits for “non-detect” values, which resulted in calculated SSCLs that are much lower than the
detection limits for these compounds. These compounds were not actually detected in the
samples, and there is no indication that these compounds are present. Additionally, these
apparent SSCL exceedances for PAH compounds are for exposure pathways that are incomplete
at this site under current and future conditions, regardless of land use type.
Using the residential land use assumption, the SSCL calculator generated similar overall output,
but with three additional apparent SSCL exceedances based on maximum soil concentrations.
These were for benzene, naphthalene, and alkyl benzenes (C9-C10), with each indicating
apparent exceedances of the soil SSCL (for soil leaching to groundwater with groundwater
ingestion), which is an incomplete exposure pathway under current and future conditions.
Additionally, the maximum concentrations of benzene, naphthalene, and alkyl benzenes (C9-
C10) detected in groundwater were below the respective groundwater SSCLs for groundwater
ingestion.
5.0 DATA QUALITY ASSESSMENT
All laboratory analytical data were subject to internal reduction and validation prior to external
release of the data, as detailed in the laboratory’s Quality Assurance Manual. Following receipt
of the laboratory analytical results by Terracon, the data were reviewed to evaluate compliance
with Data Quality Indicators (DQIs) outlined in Sections D1, D2, and D3 of the QAPP.

Documentation provided with the laboratory analytical results reports included a case narratives;
analytical data with minimum method detection limits (MDLs) and reported detection limits
(RDLs)reporting limits listed for all analyses; surrogate recoveries for GC/MS analyses with
laboratory control limits; chain-of-custody records; and a quality control summary, including
method blanks, matrix spike/matrix spike duplicates (MS/MSD) with control limits, laboratory
control samples and duplicates (LCS/LCSD) with control limits; and application of data qualifiers
where warranted.
Assessment of the DQIs for Precision, Bias and Accuracy, Representativeness, Comparability,
Completeness, and Sensitivity are presented in the following subsections.
5.1 Precision
Precision was evaluated on the basis of relative percent difference (RPD) as a measure of
reproducibility between LCS/LCSD pairs and MS/MSD pairs (analytical precision) and between
field samples and field duplicate samples (field precision ).
The RPD is calculated to evaluate precision using the following equation.
RPD =ࢄ૚ ିࢄ૛
ቀࢄ૚ +ࢄ૛
૛ ቁ
࢞૚૙૙ Where X1 and X2 are the reported concentrations of the samples
being evaluated.
5.1.1 Analytical Precision
A summary of the Quality Control assessment for analytical precision is presented below.
n Laboratory Set L1262016 (Soil and Groundwater Samples):
o The RPDs for the MS/MSD pairs associated with lead, TPH-GRO, TPH-GRO, and
TRPH were within the laboratory control limits.
o The RPD for the MS/MSD pair associated with PCB 1016 for Laboratory Batch
WG1545652 was outside the laboratory’s control limits. As a result, a J3 flag was
used to qualify this data. The affected analytes were not detected in any of the
samples analyzed and the reported detection limits were two orders of magnitude
below its residential RSL. It is not anticipated the analytical precision issue will
affect the conclusions of this report and PCB 1016 in those samples is considered
to be below the residential RSL.
o The RPDs for the LCS/LCSD pairs associated with lead, TPH-GRO, TPH-DRO,
TRPH, and PCBs were within the laboratory control limits.

Based on the results of the RPD analyses of the MS/MSD and LCS/LCSD pairs and the evaluation
provided above,analytical precision is considered within control for Laboratory Set L1262016
(Soil and Groundwater Samples).
n Laboratory Set 2009349 (Soil and Groundwater Samples):
o The RPDs for methyl tert-butyl ether, benzene, toluene, ethylbenzene, total
xylenes, and naphthalene (MBTEXN) were within the laboratory’s control limits.
o The RPDs for the MS/MSD pairs associated with analyses of polycyclic aromatic
hydrocarbons (PAHs), part of the DRO Fractionation analytical suite, for Lab Set
ID 2009349, Lab Sample ID 2009357-001BMSD, were within the laboratory’s
control limits.
o The RPDs for the MS/MSD pairs associated with analyses of PAHs for Lab Set ID
2009349, Lab Sample ID 2009349-003AMSD, were outside the laboratory’s
control limits for anthracene and benzo(k)fluoranthene. For both anthracene and
benzo(k)fluoranthene the laboratory stated the high RPDs were due to suspected
sample non-homogeneity or matrix interference. For benzo(k)fluoranthene the
laboratory also stated the matrix spike recovery indicated matrix interference, but
that the method is in control as indicated by the LCS.
Neither anthracene nor benzo(k)fluoranthene were detected in the samples
analyzed. The highest RDL reported for anthracene, 7.5 mg/kg, is well below the
SSCLs for anthracene calculated for the site (Appendix C). The highest RDL
reported for benzo(k)fluoranthene, 7.5 mg/kg, is well below the SSCLs for
benzo(k)fluoranthene calculated for the site (Appendix C), except for the soil
leaching to groundwater pathway (SSCL s-leach). As benzo(k)fluoranthene was not
reported in any of the groundwater samples, the exceedance of the SSCLs-leach by
the RDL is not anticipated to affect the conclusions of this report that
benzo(k)fluoranthene is not anticipated to be present in either soil or groundwater
at the site.
Based on the results of the RPD analyses of the MS/MSD and LCS/LCSD pairs and the evaluation
provided above,analytical precision is considered within control for Laboratory Set 2009349
(Soil and Groundwater Samples).
5.1.2 Field Precision
A total of one soil and one groundwater duplicate pairs were collected and analyzed. A summary
of the Quality Control assessment for field precision is presented below.

Per the QAPP, analytical results for original samples and field duplicate pairs that are less than
five times the laboratory’s Reported Detection Limit (RDL) in the analytical reports, were
considered within control if the difference between the sample concentration and its duplicate was
less than two times the RDL. When analytical results for the original sample and the field duplicate
pairs are greater than five times the RDL, the duplicate pair was considered within control when
the RPDs for the field duplicate pairs were within the QAPP’s control limits (50% for solid samples,
25% for groundwater samples).
n Laboratory Set L2672016 (Soil Samples):
o TPH-GRO, TPH-DRO, and TRPH (Table C7.1)
The RPDs calculated for TPH-DRO, TPH-GRO, and TRPH are considered in
control because the RPDs were less than the 50% QAPP control limit.
o Lead (Table C7.1)
The RPD calculated for total lead is considered in control because the RPD was
less than the 50% QAPP control limit.
o PCBs (Table C7.2)
Reported concentrations for most of the PCBs, except PCB 1254, were less than
the RDLs for both the original and duplicate samples and were considered within
control because the difference between the RDLs was less than two times the
RDL. One PCB (PCB 1254) had detectable concentrations in both samples. This
analyte is in control because both the original and duplicate were less than 5X RDL
and the difference between the results was less than 2X RDL.
Based on the results of the evaluation provided above,field precision is considered within
control for Laboratory Set L1262016 (Soil Samples).
n Laboratory Set L1262016 (Groundwater Samples):
o TPH-GRO, TPH-DRO, and TRPH (Table C7.3)
TPH-GRO and TRPH are considered in control because both the original and
duplicate were less than 5X RDL and the difference between the results was less
than 2X RDL. TPH-DRO is in control because the calculated RPD is less than the
25% QAPP control limit.
o PCBs (Table C7.4)
PCBs are considered within control because PCBs were less than the RDLs in
both the original and duplicate samples and the difference between the RDLs was
less than two times the RDL.

difference between the RDLs was less than two times the RDL. RPDs were
calculated for C11-C12 aliphatic hydrocarbons, C11-C13 alkyl naphthalenes, C13-
C16 aliphatic hydrocarbons, C17-C21 aliphatic hydrocarbons, and C22-C25
aliphatic hydrocarbons and they were considered in control because the RPDs

5.2 Bias and Accuracy
Bias and Accuracy were evaluated through a review of the method blanks, trip blanks, percent
recoveries for LCS/LCSD, and percent recoveries for MS/MSD summaries provided by the
laboratory. Method blanks and trip blanks were considered within control (i.e.,accuracy ) if the
constituents analyzed were less than the analytical method reporting limits. LCS/LCSD and
MS/MSD analyses were considered within control if the percent recoveries were within the
laboratory’s established limits (i.e.,bias ). A summary of the Quality Control assessment for Bias
and Accuracy is presented below.

n Laboratory Set L1262016 (Soil and Groundwater Samples):
o Accuracy – Method Blank: All analytes in the method blanks were less than the
laboratory RDLs. TPH-GRO was detected in the method blank for Batch
WG1545597 in an estimated concentration below its RDL (J flag). One of the
affected samples (LT-B-17@10’) was detected at 158 mg/kg, which slightly
exceeds the UDEQ ISL of 150 mg/kg. Based on the very low detection of TPH-
GRO in the method blank (0.0449 mg/kg), it is unlikely this would affect the
conclusion that TPH-GRO exceeds its ISL in this location.
o Accuracy – Trip Blank: A trip blank was analyzed for TPH-GRO. Results for
TPH-GRO were less than the RDLs.
o Bias – LCS/LCSD Percent Recoveries:The percent recoveries of the analytes
in the LCS and LCSD for TPH-GRO, TPH-DRO, TRPH, lead, and PCBs were
within the laboratory’s quality control ranges.
o Bias – MS/MSD Percent Recoveries:The percent recoveries for all the analytes
in the MS and MSD were within the laboratory’s control limits for TPH-GRO, TPH-
DRO, TRPH, lead, and PCBs.

o Accuracy – Method Blank: All analytes in the method blanks were less than the
RDLs.
o Accuracy – Trip Blank: A trip blank was analyzed for TPH-GRO Fractionation.
All results for TPH-GRO Fractionation were less than the RDLs.
o Bias – LCS/LCSD Percent Recoveries:The percent recoveries of the analytes
in the LCS for TPH-DRO and TPH-GRO Fractionation were within the laboratory’s
quality control ranges.
o Bias – MS/MSD Percent Recoveries:The percent recoveries for all the analytes
in the MS and MSD were within the laboratory’s control limits for TPH-DRO
Fractionation and TPH-GRO Fractionation, except for anthracene,
benzo(k)fluoranthene, and pyrene in Lab Sample ID 2009349-003AMS/MSD.
Phenanthrene’s recovery was also outside of the laboratory’s control limits in Lab

these constituents were not reported in any of the samples analyzed above their
RDLs, this bias issue is not anticipated to affect the conclusions of this report that
they are not present in the soil samples collected at the site.
The percent recoveries for MBTEXN in Lab Sample ID 2009031-009BMS/MSD
were recorded as 0. The laboratory stated sample dilution required due to sample
matrix. Surrogate and MS spiking compound recoveries were outside of the control
limits as expected due to being diluted out. The percent recoveries for MBTEXN
were within the laboratory’s control limits for Lab Sample ID 2009262-
001AMS/MSD and 2009399-002AMS/MSD, except for MTBE that recovered a
little low in sample 2009399-002AMSD. MTBE was not detected in the samples
analyzed above the RDLs. While one of the MS/MSD pairs had to be diluted and
had poor recoveries, the other two were generally within the control limits. As such,
recoveries for the MS/MSD pairs are considered within control.
Bias and Accuracy are considered within control for Laboratory Set 2009349.
5.3 Representativeness
Representativeness is a qualitative parameter most concerned with proper design and execution
of the sampling program to produce data that accurately and precisely represent environmental
conditions. Selection of analytical methods, sampling methods and locations representative of
the media sampled were set forth in the SAP.Representativeness in the field was achieved by
implementing the approved SAP and using appropriate sampling methods, sample containers,
sample handling and preservation methods.Representativeness in the laboratory was achieved
by using the proper analytical procedures, meeting sample holding times, and analyzing and
assessing laboratory QA/QC samples.
Field Representativeness
Sampling was conducted in general accordance with the Sampling and Analysis Plan (SAP) and
associated Standard Operating Procedures.
Laboratory Representativeness
Sample analyses followed the analytical methods listed in the SAP or equivalent EPA-approved
methods or variations of the listed methods.
Sample analyses were performed within the specified holdings times for all the project samples.
TPH-DRO and TPH-GRO Fractionation analyses were conducted by American West Analytical
Laboratories (AWAL). AWAL was subcontracted by Pace Analytical for this work. AWAL is
accredited by the National Environmental Laboratory Accreditation Program (NELAP) in Utah,
and all analyses were performed in accordance with NELAP protocols.

Representativeness is considered within control.
5.4 Comparability
Comparability is a qualitative term expressing the confidence with which one data set can be
compared to another. The comparability goal was achieved using standardized sampling
procedures in accordance with the SAP and QAPP, use of standardized and approved laboratory
analytical methods, and reporting the analytical results in appropriate and consistent units.
n Sampling was conducted in general accordance with the Sampling and Analysis Plan
(SAP) and associated Standard Operating Procedures. Deviations from the SAP
occurred during the sampling event and are discussed in Section 5.3.
n Sample analyses followed the analytical methods listed in the SAP or equivalent EPA-
approved methods or variations of the listed methods.
n The units of measure reported by the laboratories were consistent with the units of
measure used by the regulatory Screening Levels.
n The number of field duplicates specified in the approved SAP was 10% of the field
samples.
o TPH-GRO:One field duplicate for three soil samples or 33.3%, which exceeds the
10% goal. One field duplicate for two groundwater samples or 50.0%, which
exceeds the 10% goal.
o TPH-DRO: One field duplicate for three soil samples or 33.3%, which exceeds the
10% goal. One field duplicate for two groundwater samples or 50.0%, which
exceeds the 10% goal.
o TRPH: One field duplicate for three soil samples or 33.3%, which exceeds the 10%
goal. One field duplicate for two groundwater samples or 50.0%, which exceeds
the 10% goal.
o Lead: One field duplicate for two soil samples or 50%, which exceeds the 10%
goal.
o PCBs: One field duplicate for two soil samples or 50%, which exceeds the 10%
goal. One field duplicate for two groundwater samples or 50.0%, which exceeds
the 10% goal.
Comparability is considered within control.

5.5 Completeness
Completeness is the ratio of valid measurements to the number of planned measurements,
expressed as a percentage, and the completeness goal for the project is 90%. The sampling
program is deemed to meet the DQIs for valid measurements, with the following exceptions.
n Analytical Precision issue:The RPD for the MS/MSD pair for PCB 1016 was outside
of the control limits .
PCB 1016 was less than the RDL for the affected samples and this in not anticipated
to affect the usability of the data and PCB 1016 in those samples is considered to be
below the residential RSL.
n Analytical Precision issue:The RPDs for the MS/MSD pairs for anthracene and
benzo(k)fluoranthene were outside of the control limits.Sample non-homogeneity was
suspected.
Neither anthracene nor benzo(k)fluoranthene were detected in the samples analyzed
and the RDLs were generally less than the SSCLs calculated for the site. Neither
constituent is anticipated to be present in the samples analyzed.
n Accuracy issue:TPH-GRO was detected in the method blank.
One of the affected samples (LT-B-17@10’) was detected at 158 mg/kg, which slightly
exceeds the UDEQ ISL of 150 mg/kg. Based on the very low detection of TPH-GRO
in the method blank (0.0449 mg/kg), it is unlikely this would affect the conclusion that
TPH-GRO exceeds its ISL in this location.
n Bias issue:The percent recoveries for anthracene, benzo(k)fluoranthene,
phenanthrene, and pyrene were outside of the laboratory’s control limits, likely due to
matrix interference.
As these constituents were not reported in any of the samples analyzed above their
RDLs, this bias issue is not anticipated to affect the conclusions of this report that they
are not present in the soil samples collected at the site.
n Bias issue:The percent recoveries for MBTEXN were outside of the laboratory’s
control limits in one sample due to sample dilution.
While one of the MS/MSD pairs had to be diluted and had poor recoveries, the other
two were generally within the control limits. As such, recoveries for the MS/MSD pairs
are considered within control.

While the above issues were identified, none were determined to affect the usability of the
data. As such, the analytical data are acceptable for their intended use to evaluate
constituent concentrations compared to applicable regulatory Screening Levels.
5.6 Sensitivity
Sensitivity refers to the capability of a method or instrument to discriminate between measurement
responses representing different Levels of the variable of interest. The sensitivity goal is for RDLs
to be below comparative Screening Levels, which vary considerably by analyte and in value and
applicability. Overall, the level of sensitivity was sufficient to allow the identification of soil and
groundwater constituents above applicable regulatory Screening Levels.
n Laboratory Set L1262016 (Soil Samples):
o TPH-GRO (Table C.1):The RDLs were all less than the Utah ISLs and Utah Tier
1 Screening Levels for analytes reported as less than the RDL.
o TPH-DRO (Table C.1): The RDLs were all less than the Utah ISLs and Utah Tier
1 Screening Levels for analytes reported as less than the RDL.

Screening Levels for analytes reported as less than the RDL.
o Lead (Table C.1): The RDLs were all less than the EPA RSLs for lead.
o PCBs (Table C.2): The RDLs were all less than the EPA RSLs for PCBs.
n Laboratory Set L1262016 (Groundwater Samples):
o TPH-GRO (Table C.3):The RDLs were all less than the Utah ISLs and Utah Tier
1 Screening Levels for analytes reported as less than the RDL.
o TPH-DRO (Table C.3):The RDLs were all less than the Utah ISLs and Utah Tier
1 Screening Levels for analytes reported as less than the RDL.
o TRPH (Table C.3):The RDLs were all less than the Utah ISLs and Utah Tier 1
Screening Levels for analytes reported as less than the RDL.
o PCBs (Table C.4):EPA MCLs, Utah ISLs, and Utah Tier 1 Screening Levels are
not established for PCBs. Several PCB RDLs were greater than EPA Residential
VISLs. The MDLs were below these VISLs. However, these constituents were
less than the RDLs in each of the samples. These are not anticipated to affect the
conclusions of this report.

o TPH-GRO Fractionation (Table 2):RDLs for benzene exceeded SSCL Levels
for leaching to groundwater. Benzene was not detected above the RDL in the
sample. This are not anticipated to affect the conclusions of this report. RDLs for
C9-C10 alkyl benzenes and C7-C8 aliphatics exceed some SSCLs. However, the
concentrations of these components in the affected sample is much greater than
these Levels.
o TPH-DRO Fractionation (Table 2):Several RDLs for PAH fractionation
components exceeded SSCL Levels for leaching to groundwater and ingestion or
inhalation. However, none of these PAHs were detected above RDLs in any of the
samples. These are not anticipated to affect the conclusions of this report.
n Laboratory Set 2009349 (Groundwater Samples):
o TPH-DRO (Table 4):Several RDLs for PAH fractionation components exceeded
SSCL Levels for groundwater ingestion. However, none of these PAHs were

o
o TPH-GRO (Table 4):No RDLs of fractionation components exceeded SSCL
Levels for groundwater.
The DQIs for Comparability were achieved. As such,Comparability was deemed acceptable.
6.0 DATA EVALUATION
Following is an overview of the identified contaminants in soil and groundwater to date.
Subsurface soils and groundwater exceeding the UDEQ Screening Levels for TRPH and TPH-
DRO were reported across the site. None of the soil or groundwater samples identified any
BTEXN or MTBE constituent concentrations above ISLs or Tier 1 Screening Levels. Free product,
likely associated with hydraulic oil, was reported in borings B-10 and B-15.
Lead exceeded the EPA industrial RSL in soil in boring B-15 at 10’. Lead-impacted soils appear
to be limited to this area as no other soil samples reported elevated lead and are likely associated
with the oil/water separator.
Two groundwater samples, B-12 (0.0392 mg/l) and B-16 (0.0963 mg/l) reported dissolved arsenic
above the MCL of 0.01 mg/l. Boring B-16 additionally exceeded the UGWQS of 0.05 mg/l.

The TPH Fractionation results indicate that the hydrocarbons present in soils and groundwater
are predominately residual “heavy-end” or large carbon chain petroleum associated with diesel
and oils (including hydraulic oil). Evaluation using the DERR SSCL calculator indicates several
apparent exceedances of calculated SSCLs, but for exposure pathways that are incomplete under
current and future conditions for both commercial and residential land use. Many of the apparent
SSCL exceedances are artifacts of the calculator algorithms, which require input of the detection
limits for “non-detect” values; this results in calculated SSCL values that are much lower than the
detection limits for many compounds (i.e., the laboratory analyses do not indicate that the
offending compounds are actually present). The exposure pathways for the apparent SSCL
exceedances are incomplete because 1) site groundwater is not extracted and used for drinking
water or for any other purposes; 2) the impacted soils are at depth and physically isolated from
potential exposure by ingestion, inhalation, or dermal contact; and 3) the apparent exceedance
of the subsurface soil SSCL for aliphatics (C7-C8), for the indoor air vapor inhalation pathway, is
not supported by the groundwater data or the sub-slab vapor data.
7.0 CONCLUSIONS AND RECOMMENDATIONS
Evaluation of the TPH fractions, site-specific conditions, and exposure pathways in the context of
the planned site use (incorporation of the existing buildings into a future re-development) supports
the remedial approach recommended in the Remedial Alternatives Evaluation. The overall
remedial approach involves removal of contaminant source structures (hydraulic hoists, sump,
floor drains), conducting targeted removal of free product to address the remaining onsite source
of groundwater contamination, and reliance on the current understanding of the TPH fractions.
The remaining TPH in soil and groundwater can be managed with controls such as restrictions
on groundwater use, maintenance of existing physical barriers over the impacted soils at depth,
and establishment of soil management procedures to be followed in the event of future excavation
activity.
Such controls would need to be specified in a Site Management Plan and Environmental
Covenant under regulatory oversight and maintained during future site use to ensure that all
exposure pathways remain incomplete. Terracon recommends consultation with the appropriate
UDEQ agency for regulatory oversight, input, and approval on remediation and management of
the site.

RE:
American West Analytical Laboratories received sample(s) on 9/14/2020 for the analyses
presented in the following report.
American West Analytical Laboratories (AWAL) is accredited by The National
Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is
state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri.
All analyses were performed in accordance to the NELAP protocols unless noted
otherwise. Accreditation scope documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
Thank You,

ONE LAB. NATIONWIDE.CASE NARRATIVE
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. 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.

ONE LAB. NATIONWIDE.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
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)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.
J3 The associated batch QC was outside the established quality control range for precision.
P RPD between the primary and confirmatory analysis exceeded 40%.

1.0 INTRODUCTION
1.1 Site Description
Site Name Lelis Transmissions
Site Location/Address 845 South Main Street, Salt Lake City, Utah
General Site Description The site is occupied by three joined buildings that are used by the
Lelis Transmission automotive repair facility. The remaining
portions of the site are covered with an asphalt parking lot.
Exhibit 1 (Appendix A) presents the site location on a portion of the USGS 7.5-minute series
topographic map. Exhibit 2 is a site diagram that indicates the approximate locations of the soil
and groundwater sampling points in relation to pertinent site features.
1.2 Project Background
The property is located at 845 South Main Street, Utah, and is occupied by the Lelis
Transmissions shop. Terracon understands that a subsurface investigation was conducted on
March 12, 2015, on the south-adjoining properties (857 and 865 South Main Street) as part of a
potential property transaction. During the investigation, diesel contamination was discovered in
the soil and groundwater on the adjoining properties at concentrations above regulatory limits.
A petroleum release was reported to the Utah Department of Environmental Quality (UDEQ),
Division of Environmental Response and Remediation (DERR) on March 25, 2015, and the
DERR responded with a request to investigate the area of the former underground storage tank
(UST) that was removed from the Lelis Transmission site in 1991.
1.3 Scope of Work
Our scope of services involved conducting a Limited Site Investigation (LSI) to assess whether
subsurface soil and/or groundwater beneath the site in the area of the former UST remain
above regulatory limits and assess the level of impact to the site’s soil and groundwater. The
LSI was conducted through a series of drilled borings to allow the collection of subsurface soil
and groundwater samples for laboratory analysis for the type(s) of contaminants most likely to
be present at each proposed boring location. Terracon’s LSI included advancement of three
soil borings to groundwater to collect soil and/or groundwater samples. Our work scope was
designed to assess the potential presence of benzene, toluene, ethylbenzene, xylenes,
naphthalene (BTEXN), methyl t-butyl ether (MTBE); total petroleum hydrocarbons – diesel

range organics (TPH-DRO), and TPH -gasoline range organics (TPH-GRO) to determine the
impact to soil and groundwater at the site in the vicinity of the former gasoline UST and the
adjoining building to the south.
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
time period. Please note that Terracon does not warrant the work of laboratories, regulatory
agencies or other third parties supplying information used in the preparation of the report.
These LSI 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 LSI. 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 LSI report has been prepared for the exclusive use and reliance of Lelis Transmissions and
government entities having jurisdiction over the site. Use or reliance by any other party is
prohibited without the written authorization of the client and Terracon. Reliance on the LSI

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 LSI field activities were conducted on May 28, 2015. As part of the approved scope
of work, Terracon advanced three environmental soil borings at locations judged most likely to
detect the presence of contaminants, if present. The approximate boring locations are shown
on Exhibit 2 (Appendix A). All borings were advanced using direct-push drilling equipment.
After completion of sampling at each boring, the boring was properly abandoned by backfilling
with bentonite clay pellets, adding water to hydrate the bentonite clay, and restoring the surface
with quick-set concrete patch as appropriate to match the surrounding area.
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 Field
Geologist. Mechanized drilling equipment was cleaned using a high-pressure washer prior to
beginning the project and before beginning each soil boring. Soil samples were collected
continuously from all soil borings, using a five-foot macro-core sampler.
Soil samples were observed to document subsurface 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 evaluate the potential presence
of total volatile organic compounds (TVOCs). The subsurface materials encountered generally
consisted of fill material underlain by silts, clays, and gravels. Groundwater was encountered at
depths of approximately 10 below grade surface (bgs). Detailed lithological descriptions and
PID readings are included on the soil boring logs provided in Appendix B.
2.2 Subsurface Soil Sampling
Terracon's LSI soil sampling program generally involved (unless otherwise specified) collecting
and submitting for laboratory analysis one soil sample from each of the soil borings. Soil
samples were collected from the zone exhibiting the highest potential for environmental impact
based on field observations and PID readings. If no elevated PID readings were observed, the
sample was collected from the capillary fringe zone, from the interval exhibiting a change in
lithology, from the bottom of the boring, or from the interval of most likely environmental impact
as determined in the field by the sampling professional.
2.3 Groundwater Sampling
Groundwater samples were collected from each of the borings (converted to temporary
groundwater sampling points using direct-push tooling with a retractable well screen), using a
Limited Site Investigation Report

low-flow peristaltic pump. A section of dedicated polyethylene sample tubing was inserted into
the drive point. The sample tubing was connected to a dedicated section of flexible
polyethylene hose at the surface. This tubing was passed through a low-flow peristaltic hose
pump used to develop the sampling point, as needed to reduce turbidity, and to purge the water
column within the tool. Following probe development, the peristaltic pump was used to collect a
groundwater sample directly into the appropriate laboratory-provided containers.
3.0 LABORATORY ANALYTICAL METHODS
All soil and groundwater samples were collected and placed in laboratory-prepared glassware
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 soil and groundwater samples collected from the borings were analyzed on a standard
turnaround by laboratory test methods as appropriate for the type(s) of contaminants most likely
to be encountered at each location. This included BTEXN, MTBE, TPH-DRO, and TPH-GRO.
Samples were analyzed using the following methods:
Analysis Sample Type No. of Samples Laboratory Method
MTBE, BTEXN and TPH-
GRO Soil 3 EPA Method 8260
MTBE, BTEXN and TPH-
GRO Groundwater 3 EPA Method 8260
TPH-DRO Soil 3 EPA Method 8015
TPH-DRO Groundwater 3 EPA Method 8015
The executed chain-of-custody form and laboratory data sheets are provided in Appendix D.
4.0 LSI DATA EVALUATION
Please refer to Table 1 (Appendix C) for a summary of the laboratory analytical results for all
soil samples. Please refer to Table 2 (Appendix C) for a summary of the laboratory analytical
results for all groundwater samples. The executed chain-of-custody form and laboratory data
sheets are provided in Appendix D.
Tables 1 and 2 also include comparative regulatory screening levels. For petroleum
constituents that were detected, the regulatory screening levels included Initial Screening Levels
(ISLs) and Tier 1 Screening Levels established by the DERR.

4.1 Results for Soil Samples
TPH-DRO was detected in the soil samples collected from soil borings B-1, B-2, and B-3 at a
depth of 10 feet bgs at concentrations of 4,530 milligrams per kilogram (mg/kg), 2,810 mg/kg,
and 3,820 mg/kg, respectively. The concentrations of TPH-DRO reported in these samples are
above the ISLs of 500 mg/kg, but below the Tier 1 limit of 5,000 mg/kg.
TPH-GRO was detected in the soil samples collected from soil borings B-1, B-2, and B-3 at a
depth of 10 feet bgs at concentrations of 152 mg/kg, 179 mg/kg, and 209 mg/kg, respectively.
The concentrations of TPH-GRO reported in these samples are above the ISLs of 150 mg/kg,
but below the Tier 1 limit of 1,500 mg/kg.
No other constituents were detected above laboratory reporting limits and/or applicable
screening levels in any of the soil samples analyzed.
4.2 Results for Groundwater Samples
TPH-DRO was detected in the groundwater samples collected from soil borings B-1, B-2, and
B-3 at concentrations of 1,500 milligrams per liter (mg/L), 6.8 mg/L, and 9.5 mg/L, respectively.
The concentrations of TPH-DRO reported in these samples are above the ISL of 1 mg/L, but
below the Tier 1 limit of 10 mg/L, with the exception of the groundwater sample from B-1, which
also exceeds the Tier 1 limit.
TPH-GRO was detected in the groundwater sample collected from soil boring B-1 at
concentrations of 7.2 mg/L. The concentration of TPH-GRO reported in this sample is above
the ISL of 1 mg/L, but below the Tier 1 limit of 10 mg/L.
No other constituents were detected above laboratory reporting limits and/or applicable
screening levels in any of the soil samples analyzed.
5.0 FINDINGS AND CONCLUSIONS
A petroleum release was reported to the DERR on March 25, 2015, at the adjoining property
located south of the site. The DERR responded with a request to Lelis Transmissions to
investigate the area of the former UST that was removed from the site in 1991. This LSI
involved collecting subsurface soil and groundwater samples for laboratory analysis for the
type(s) of contaminants most likely to be present at each area of concern.
TPH-DRO was the contaminant with the highest concentrations identified in the soil and
groundwater of this investigation. Lelis Transmissions previously had a gasoline, not a diesel
UST, and that UST was closed by removal from the site in 1991. The highest TPH-DRO
concentrations in the soil and groundwater at the site were identified at soil boring B-1, located
immediately adjacent to the building located south of the site. The two soil borings advanced

down-gradient and adjacent to the former gasoline UST location had levels of TPH-DRO and
GRO in the soil above ISLs, but below Tier 1. The TPH-DRO levels were significantly higher
than the TPH-GRO at this location as well. TPH-GRO and other gasoline constituents were not
detected in the groundwater at concentrations above ISLs near the former UST. The observed
distribution of contaminants appears to indicate an off-site contaminant source.
It is Terracon’s opinion that the TPH-DRO and TPH-GRO contaminants identified during this
investigation did not originate from the site, but possibly from the adjoining property to the south
or from another location further up-gradient from the site. As such, Lelis Transmissions does
not appear to be the responsible party and should not be required to conduct further
investigation or corrective action at this time.
Terracon recommends that if subsurface soils or groundwater that are disturbed during future
construction activities exhibit staining, noxious odors, sheens, or any other abnormalities that
suggest the potential presence of contaminants, then proper procedures should be followed with
respect to worker health and safety, and any impacted soil or groundwater encountered should
be properly characterized, treated and/or disposed in accordance with applicable local, state or
federal regulations.
Terracon appreciates being of service to you on this project. If you have any questions, require
additional information, or need additional assistance, please contact us.

ONE LAB. NATIONWIDE.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. 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.

MDL Method Detection Limit.
RDL Reported Detection Limit.
ND,U Not detected at the Reporting Limit (or MDL where applicable).
RPD Relative Percent Difference.
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry
report basis for soils].
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.
(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.
Rec.Recovery.
SDL Sample Detection Limit.
MQL Method Quantitation Limit.
Unadj. MQL Unadjusted Method Quantitation Limit.
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.
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3 The associated batch QC was outside the established quality control range for precision.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is
low.
J7 Surrogate recovery cannot be used for control limit evaluation due to dilution.
