1.0 Introduction
Terracon Consultants, Inc. (Terracon) has completed a site characterization assessment
(site investigation) for the Gordo Property site (site) located at approximately the northwest
corner of Kearns Boulevard and Richardson Flat Road, Park City, Utah (Exhibit 1). The goal
of the project was to characterize impacts at the site stemming from use of the site to store
heavy-metals contaminated soils from development projects throughout the Park City area,
determine the risk level present at the site, and determine potential options for remediation
and redevelopment of the site.
1.1 Site Description
The site is comprised of approximately 16 acres of land currently owned by Park City
Municipal Corporation (PCMC) consisting of the addresses, Summit County Assessor Parcel
Numbers (APNs), and land uses listed below:

Survey (USGS) topographic map.
1.2 Site History and Summary of Previous Assessment and
Corrective Action
The site was historically used primarily as open space. A portion of the site was used for
vehicle parking. The site was acquired by PCMC in multiple phases from 1996 through 2008.
Beginning in 2010 and with approval from the Utah Department of Environmental Quality
(UDEQ), Division of Environmental Response and Remediation (DERR) and acknowledgment
from the United States Environmental Protection Agency (EPA), PCMC utilized the site to
temporarily stockpile approximately 34,000 cubic yards of Bevill-exempt metals-
contaminated soil excavated from mining-impacted development projects throughout the
Park City area. PCMC anticipated that the site would be developed as a permitted repository
for metals-impacted soils with oversight from UDEQ’s Division of Waste Management and
Radiation Control (DWMRC), but PCMC has since revised its development plans for the site
and intends to remediate and redevelop the site for other purposes.
Two previous investigations have been conducted at the site. A field X-ray fluorescence
(XRF) survey was conducted by AMEC Earth & Environmental (AMEC) in September 2010.
Approximately 180 locations were sampled via XRF for arsenic and lead. AMEC’s XRF data
indicated that lead impacts exceeding EPA Regional Screening Levels (RSLs) for Residential
or Industrial use were largely confined to the soil stockpile, but that limited impacts were
present on the northern portion of the site near the site entrance road.

A second investigation was conducted by Gerhart Cole Inc (GCI) in 2016. GCI collected 48
soil samples from 36 test pits located throughout the site. The results from GCI’s
investigation were largely consistent with the results of AMEC’s XRF survey and displayed a
similar pattern of impacts.
2.0 Site Characterization Scope And Methods
The following sections detail the scope and methods of the site characterization sampling
that was conducted by Terracon in June 2023 and February 2023 to investigate the data
gaps identified in the DMWRC-approved Site Characterization Workplan (SCW).
Informational data gaps identified and fully detailed in the SCW included laboratory data for
non-lead metals, metals concentrations in sub-stockpile native soils, and on-site background
metals concentrations.
2.1 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. Terracon makes no warranties, either express or implied,
regarding the findings, conclusions, or recommendations. Please note that Terracon does
not warrant the work of laboratories, regulatory agencies, or other third parties supplying
information used in the preparation of this report.
2.2 Sampling Scope
Field sampling consisted of the following data collection. Soil samples were collected and
submitted for laboratory analysis to characterize the concentrations of metals in soil at the
site. Soil samples were collected from three zones at the site (Exhibit 2).
Zone 1 consists of the soil stockpile. In Zone 1, at each sampling location one
sample was collected from the most impacted depth interval (as determined by field
XRF screening) and one sample was collected from native soils 6–12 inches beneath
the stockpile soils. Zone 1 samples were collected using a track-mounted direct-
push drill rig. Drilling depths varied according to the soil stockpile depth which
averages approximately 10 feet, but ranges from less than 5 feet to approximately
20 feet. Drilling was conducted in 5-foot increments as-needed to fully intercept
underlying native soils.
Zone 2 consists of the area near the site entrance where previous investigations
identified off-stockpile impacted soil. In Zone 2, at each sampling location one
sample was collected from near-surface soils (0–2 inches) or the most impacted
Site Characterization Report

August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 4
depth interval (as determined by field XRF screening) and one sample was collected
from shallow subsurface native soils (6–12 inches below the surface or non-native
soils, if present). Zone 2 samples were primarily collected via hand digging or hand
auger. A limited number of Zone 2 samples were collected using a track-mounted
direct-push drill rig where non-native soils were present at depths that precluded
hand digging or hand auger collection methods. These sample locations are B-12, B-
16, and B-17 (Exhibit 2).
Zone 3 consists of unimpacted native soil areas and Zone 3 sample results are
considered site-specific background concentrations for risk evaluation and screening
contaminants of potential concern (COPCs). In Zone 3, at each sampling location
one sample was collected from near-surface soils (0–2 inches) and one sample was
collected from shallow subsurface native soils (6–12 inches). Zone 3 samples were
collected via hand digging.
The SCW specified the collection of twenty samples from ten locations within each zone (two
samples at each of the ten sample locations per zone). However, some modifications were
made to this protocol based on field conditions during sampling. These deviations from the
SCW sampling protocol are fully detailed in Section 4.3. Sufficient samples were still
collected from each sampling zone and depth interval to allow for calculation of 95% Upper
Confidence Limits (UCL95) for each sampling zone and depth interval.
2.3 Sampling Methods
2.3.1 Soil Sampling
Direct-push drilling services were performed by Utah-licensed driller Direct Push Services.
Soil samples were collected continuously, using 5-foot core barrel samplers to document
lithology, color, and relative moisture content. Zone 1 soil samples were field-screened via
XRF to target the most impacted depth interval. Soil samples were collected per the
procedures detailed in Terracon Standard Operating Procedures (SOP) 1,Soil Sampling and
Logging, and Terracon SOP 5,Geoprobe Sampling.
2.3.2 Field QA/QC Samples
Field duplicates were collected at a rate of 10 percent. Six duplicate soil samples were
collected for analysis of the metals regulated by the Resource Conservation and Recovery
Act (RCRA 8).
The original sample and corresponding duplicate samples are provided below:

Z2-B29 @ 0.5 Z2-B129 @ 0.5 RCRA Metals
2.3.3 Equipment Decontamination
Clean disposable, single-use sampling equipment was used to collect soil samples and was
properly disposed of after each use. Drilling equipment was cleaned using a high-pressure
washer prior to beginning the project and between soil boring locations.
2.3.4 Site Restoration
Due to the site characteristics and the nature of the sampling, no site restoration (i.e.,
backfilling of soil borings) was required.
3.0 Site Characterization Results
The following sections summarize the laboratory analytical sample results. Sampling zones,
soil sample locations, and sample locations that exceeded screening values for lead are
presented in Exhibit 2 (exceedances for other metals co-occurred with lead exceedances). A
summary of the laboratory analytical results is provided in Table C1 (Appendix B). Soil
borings logs are provided in Appendix C. Copies of the analytical reports and sample chain-
of-custody records are provided in Appendix D.
Soil samples (including field duplicates) were placed in iced coolers and shipped under
chain-of-custody protocols via overnight courier to Pace Analytical National Center for
Testing and Innovation (Pace National) in Mt. Juliet, Tennessee (a Utah-Certified
Laboratory). Laboratory samples were delivered to the analytical laboratory within holding
times for all analytical methods.

1Includes field duplicate samples.
Constituent concentrations in soil were compared to EPA RSLs for Residential or Industrial
use and groundwater protection soil screening levels (Dilution Attenuation Factor 20 [DAF
20] SSLs).
3.1 General Characteristics
Field observations and analytical results from the imported soil stockpile in Zone 1 were
consistent with results reported by the previous investigations (Section 1.2). Observed fill
soil depths (Exhibit 3) were used to calculate the volume of imported fill soil present in the
Zone 1 stockpile. The stockpile volume was estimated to be approximately 30,000 cubic
yards which is consistent with historical estimates provided by PCMC.
As further detailed in Section 4.3, the SCW placed sample locations B-28 and B-29 in
sampling Zone 3, which was intended to be the background sampling zone. Field
observations during sampling indicated that the area near sample locations B-28 and B-29
were not in fact representative of background conditions. Thus, sampling zone boundaries
were adjusted to place sample locations B-28 and B-29 into sampling Zone 2 and sample
location B-29 was relocated approximately 50 feet north (Exhibit 2).
Specifically, field XRF screening indicated that a berm present on and in the vicinity of
sample locations B-28 and B-29 contained elevated concentrations of lead, which was
confirmed by the analytical results (Table C1). Visual observations from this berm also
indicated the potential presence of slag-like materials. The approximate boundaries and
depths of the Zone 2 berm are shown in Exhibit 3. The volume of the Zone 2 berm was
estimated to be approximately 1,200 cubic yards. Further historical aerial photograph
review indicates that the Zone 2 berm was created in the late 1990s or early 2000s and
Site Characterization Report

may pre-date PCMC’s acquisition of the site and creation of the Zone 1 soil stockpile. It is
considered likely that the berm material was imported to the site from an off-site source.
3.2 Soil Data Summary
Fifty-nine soil samples and six field duplicate samples were analyzed for RCRA 8 metals.Soil
samples were reported at concentrations exceeding the following thresholds and screening
levels (Exhibit 2,Table C1):
Arsenic
o All soil samples exceeded the EPA Residential RSL.
o Seven soil samples exceeded the EPA Industrial RSL but were below the DAF
20 SSL.

o Ten soil samples exceeded the EPA Residential RSL.
o Seven soil samples exceeded the EPA Industrial RSL.
o All soil samples that exceeded the EPA Residential RSL or Industrial RSL were
collected from imported fill material in Zone 1 or Zone 2.
o The maximum reported lead concentration was 7,810 mg/kg in sample “Z1-
B7 @ 2” collected from the soil stockpile material in Zone 1.
Selenium:
o No soil samples exceeded a screening level for selenium.
o The maximum reported selenium concentration was 8.98 mg/kg in sample
“Z1-B7 @ 2” collected from the soil stockpile material in Zone 1.
Silver:
o Four soil samples exceeded the DAF 20 SSL.
o No soil samples exceeded the EPA Residential RSL or EPA Industrial RSL.
o All soil samples that exceeded a silver screening level were collected from
imported fill material in Zone 1.
o The maximum reported silver concentration was 8.98 mg/kg in sample “Z1-
B7 @ 2” collected from the soil stockpile material in Zone 1.
Mercury:
o Six soil samples exceeded the DAF 20 SSL.
o Two soil samples exceeded the EPA Residential RSL.
o No soil samples exceeded the EPA Industrial RSL.
o All soil samples that exceeded a mercury screening level were collected from
imported fill material in Zone 1 or Zone 2.
o The maximum reported mercury concentration was 23.3 mg/kg in sample
“Z1-B7 @ 2” collected from the soil stockpile material in Zone 1.
Laboratory Method Detection Limits did not exceed a screening value for any metals.
3.3 Calculated Background Values and COPC Screening
UCL95s were calculated for each sampling zone and depth interval to determine site-specific
background values and screen COPCs (Table C3). Calculated UCL95s are presented in Table
C3. As noted in Table C3, UCL95s could not be calculated for selenium in all sampling zones
and depth intervals due to an insufficient number of detections. Insufficient detections also
prevented calculation of UCL95s for silver in shallow subsurface native soils in Zone 3 and
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 9
for mercury in sub-fill native soils in Zone 1. The highest detected concentrations were
substituted in these cases. Additionally, all Zone 1 sub-fill native soil samples were non-
detect for silver and the highest laboratory method detection limit was substituted.
All calculated background metals concentrations in Zone 3 were below RSLs and DAF 20
SSLs except for arsenic. Site-specific background concentrations of arsenic in soil are
estimated to range from approximately 12 mg/kg to 26 mg/kg. Arsenic UCL95s for
subsurface native soils in Zone 1 and Zone 2 are within the estimated background range.
Comparison of Zone 3 UCL95s and UCL95 substitutes to Zone 1 UCL95s and UCL95
substitutes indicates that all RCRA 8 metals except barium are retained as COPCs in Zone 1.
Zone 2 UCL95s and UCL95 substitutes indicate that cadmium, mercury, and selenium could
potentially be excluded as COPCs, but were included in risk calculations for comparability to
Zone 1 risks. A full risk evaluation is presented in Appendix E.
Zone 3 UCL95s and UCL95 substitutes indicate that subsurface native soils in Zone 1 and
Zone 2 have not been impacted by leaching from overlying non-native contaminated soils.
Subsurface native soils in Zone 1 and Zone 2 are consistent with background concentrations
present in Zone 3 samples.
4.0 Data Quality Assessment
Laboratory analytical data was 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 procedures for sampling, data generation and analysis, and reporting
outlined in Sections 3.2.1 through 3.2.10 of the SCW.
Documentation provided with the laboratory analytical results reports included case
narratives; analytical data with minimum method detection limits (MDLs) and reported
detection limits (RDLs) reporting limits listed for all analyses; 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 Precision, Bias and Accuracy, Representativeness, Comparability,
Completeness, and Sensitivity parameters are presented in the following subsections.
4.1 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).
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 10
The RPD is calculated to evaluate precision using the following equation.
RPD =𝑿𝟎−𝑿𝟎
ቀ𝑿𝟎+𝑿𝟎
𝟎ቁ
𝒙𝟎𝟎𝟎Where X1 and X2 are the reported concentrations of the
samples being evaluated.
4.1.1 Analytical Precision
A summary of the Quality Control assessment for analytical precision is presented below.
Laboratory Set L1635370 (Soil Samples):
o The RPDs for the MSD (Laboratory Batch WG2095582) for lead, the MSD
(Laboratory Batch WG2095621) for barium, and the MSD (Laboratory Batch
WG2096855) associated with chromium were outside the laboratory’s control
limits. As a result, a J3 flag was used to qualify this data. The affected
barium and chromium samples were detected in concentrations well below
regulatory screening levels as were all other samples. Several non-affected
lead samples were detected above regulatory screening levels, and other
DQIs were in control. It is not anticipated the analytical precision issue will
affect the conclusions of this report.
Based on the results of the RPD analyses of the LCS/LCSD and MS/MSD samples and the
evaluation provided above,analytical precision is considered within control for
Laboratory Set L1635370.
4.1.2 Field Precision
Six field duplicate soil samples were collected and analyzed. A summary of the Quality
Control assessment for field precision is presented below.
Analytical results for original samples and field duplicate pairs that are less than five times
the laboratory’s 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 50%.
Laboratory Set L1635370 (Soil Samples):
o Arsenic in soil for duplicate pairs Z1-B6@12/Z1-B106@12 and Z3-B22@0/Z3-
B122@0 had the original result greater than 5 X RDL and the duplicate result
less than 5 X RDL but had a difference greater than 2 X RDL. These are not
considered within control. Additionally, the calculated RPD for arsenic for
duplicate pair Z2-B29@0.5/Z2-B129@0.5 was 76.9%, above the 50% limit.
This pair is not considered within control. The other arsenic duplicate pairs
were in control. All arsenic samples were above the Residential RSL with
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 11
several above the Industrial RSL. This is not expected to affect the usability of
this data or the conclusions of this report.
o Cadmium in Duplicate pair Z2-B29@0.5/Z2-B129@0.5 had a calculated RPD
for of 74.3%, above the 50% limit. This pair is not considered within control.
The other cadmium pairs were in control. Several cadmium samples were
well above a regulatory screening level. This is not expected to affect the
usability of this data or the conclusions of this report.
o Chromium in soil for Duplicate pairs Z1-B6@12/Z1-B106@12 and Z3-
B22@0/Z3-B122@0 had the original result greater than 5 X RDL and the
duplicate result less than 5 X RDL but had a difference greater than 2 X RDL.
These are not considered within control. Additionally, the calculated RPD for
arsenic for duplicate pair Z3-B22@0/Z3-B122@0 was 72.6%, above the 50%
limit. This pair is not considered within control. The other chromium duplicate
pairs were in control, and all chromium concentrations were well below any
regulatory screening levels. This is not expected to affect the usability of this
data or the conclusions of this report.
o Duplicate pair Z2-B29@0.5/Z2-B129@0.5 had a calculated RPD for lead of
63.7%, above the 50% limit. The other lead duplicate pairs were in control,
and several lead concentrations were well above regulatory screening levels.
This is not expected to affect the usability of this data or the conclusions of
this report.
o Duplicate pair Z2-B11@0.5/Z2-B111@0.5 had a calculated RPD for silver of
56.8%, above the 50% limit. The other silver duplicate pairs were in control.
Silver concentrations in all samples were well below RSLs. This is not
expected to affect the usability of this data or the conclusions of this report.
Based on the results of the RPD analyses of the field duplicate sample pairs and the
evaluation provided above,field precision is considered within control for Laboratory
Set L1635370.
4.2 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.

the laboratory RDLs with the exception of an estimated concentration (J
value) in the method blank for selenium (Batch WG2095605). A B flag was
applied to this data. Selenium in the affected soil sample was detected at a
concentration well below regulatory screening levels. It is not anticipated
that the accuracy issue will affect the conclusions of this report.
o Accuracy–Trip Blank: A trip blank was not submitted for the metals
analysis.
o Surrogate Recoveries:Surrogate recoveries were within control.
o Bias–LCS/LCSD Percent Recoveries:The LCS/LCSD recoveries were within
control. A LCSD sample was not analyzed for metals.
o Bias–MS/MSD Percent Recoveries:The MS/MSD for mercury (Batch
WG2095468) interfered with the ability to make any accurate determination,
causing a high spike value. A J5 qualifier was applied to this data. The
affected sample was well below regulatory screening levels. This is not
expected to affect the usability of the data.
The MSD for lead (Batch WG2095582) and MS for barium (Batch
WG2095621) interfered with the ability to make any accurate determination,
causing a high spike value. A J5 qualifier was applied to this data. The
affected duplicate sample was well below regulatory screening levels. This is
not expected to affect the usability of the data.
The MS for lead (Batch WG2095582), MS/MSD for lead (Batch WB2095604),
MSD for barium (WG2095621), and MSD for arsenic and barium (Batch
WG2096855) interfered with the ability to make any accurate determination
causing a low spike value. A J6 qualifier was applied to this data. The affected
samples had barium concentrations well below regulatory screening levels.
The affected arsenic sample had a concentration well above regulatory
screening levels. This is not expected to affect the usability of the data.
Bias and Accuracy are considered within control for Laboratory Set L1635370. Some
minor exceptions exist but are not expected to have an impact on the usability of the
results.
4.3 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
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 13
representative of the media sampled were set forth in the SCW.Representativeness in the
field was achieved by implementing the approved SCW 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 SCW and associated Standard
Operating Procedures. The following deviations from the SCW occurred during the sampling
event.
Due to drilling refusal on shallow bedrock a native soil sample could not be collected
from beneath the contaminated soil stockpile at sample location B-10 in Zone 1. The
inability to collect this sample did not impact the ability to calculate UCL95s for sub-
pile native soils in Zone 1 and thus did not have a significant impact on the overall
data evaluation.
Sample location B-29 was adjusted approximately 50 feet north to the toe of a berm
that was identified as a suspect feature in the field.
The SCW placed sample locations B-28 and B-29 in sampling Zone 3, which was
intended to be the background sampling zone. Field observations during sampling
indicated that sample locations B-28 and B-29 were not in fact representative of
background conditions. Thus, sampling zone boundaries were adjusted to place
sample locations B-28 and B-29 into sampling Zone 2. The relocation of sample
locations B-28 and B-29 into sampling Zone 2 did not impact the ability to calculate
UCL95s for background metals concentrations in Zone 3 and thus did not have a
significant impact on the overall data evaluation.
Laboratory Representativeness
Sample analyses followed the analytical methods listed in the SCW or equivalent EPA-
approved variations of the listed methods.
Sample analyses followed the analytical methods listed in the SCW or equivalent
EPA-approved methods or variations of the listed methods; and were analyzed
within method-specified holding times.
The laboratory noted that the sample concentration in lead (Batch WG2096855) in
the MS/MSD is too high to evaluate accurate spike recoveries. A V value was
assigned to this data. The affected soil sample was well above regulatory reporting
limits as were several other samples. Additionally, other DQIs were considered
acceptable. This is not expected to affect the usability of the data or alter the
conclusions of this report.
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 14
The laboratory noted that mercury (Batch WG2095468) barium (Batch WG2095621)
and barium, chromium, and lead (Batch WG2096855) failed the method serial
dilution test and/or subsequent post-spike criteria, indicating matrix interference. A
O1 value was applied to this data. The affected samples were well below regulatory
screening levels for mercury, barium, and chromium. The affected lead sample was
well above regulatory screening levels as were several other samples. This is not
expected to affect the usability of the data or alter the conclusions of this report.
A MS/MSD sample for some of the metals analyses was not from a field provided
sample. Other DQIs were in control, and a LCS sample was run. This issue is not
expected to have an effect on the usability of the data.
Representativeness is considered within control.
4.4 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 SCW, use of standardized and approved laboratory
analytical methods, and reporting the analytical results in appropriate and consistent units.
Sampling was conducted in general accordance with the SCW and associated
SOPs. Deviations from the SCW occurred during the sampling event and are
discussed in Section 4.3.
Sample analyses followed the analytical methods listed in the SCW, equivalent
approved methods, or variations of the listed methods.
The units of measure reported by the laboratory were consistent with the units of
measure used by the regulatory screening levels.
The number of field duplicates specified in the approved SCW was at least 10% of
the field samples.
o Soil Samples
RCRA 8 Metals: Six field duplicate samples for fifty-nine soil samples
or 10.2%, which meets to 10% goal.
Comparability is considered within control.
4.5 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% of valid measurements. The samples collected were submitted and analyzed by
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 15
the laboratory according to the chain-of-custody. Additionally, the data collection
followed the procedures and requirements as described in the approved SCW. The SCW
detailed 66 soil samples (including field duplicates), all of which except one were
properly collected and analyzed by the laboratory. The data are considered usable as
qualified. The analytical completeness for this sampling event was 98.5%.
With acknowledgement of qualified results for the analytes listed above, the
analytical data are acceptable for their intended use to evaluate constituent
concentrations compared to applicable regulatory screening levels.
4.6 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 constituents above applicable regulatory
screening levels.
Laboratory Set L1635370 (Soil Samples):
o RCRA 8 Metals: The RDLs were all less than the EPA RSLs and DAF 20 SSLs,
as applicable, for analytes reported as less than the RDL.
The DQIs for Sensitivity were achieved. As such,Sensitivity was deemed acceptable.
5.0 Updated Conceptual Site Model
This update to the conceptual site model (CSM) refines the initial CSM that was presented in
the SCW and presents the current understanding of the site. The goals of the updated CSM
are to:
Identify the contaminants of concern, their relative subsurface distribution, and
related environmental concerns.
Define the remedial goals associated with the environmental concerns.
Identify informational data gaps and appropriate next steps.
The subsections identified below are core components to the updated CSM.
5.1 Geologic and Hydrogeologic Information and Setting
Near-surface soils are mapped as Ayoub cobbly loam, 2 to 15 percent slopes, composed of
slope alluvium derived from andesite over residuum weathered from andesite (NRCS 2023).
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 16
Surficial geologic units at the site are mapped as alluvium and glacial deposits (Qoa) and
breccia of Silver Creek (Tksc) (USGS 1971). Borings logs (Appendix C) from locations that
were sampled via direct-push soil borings indicate that low-permeability clay soils are likely
present below a large portion of the site and the Zone 1 soil stockpile specifically. Drilling
refusal at location B-10 suggests that bedrock may be present at shallow depths across the
site, which may also serve to limit infiltration.
Groundwater was not encountered during the investigation, which indicates that the depth
to groundwater is likely to be greater than 20 feet below ground surface (bgs) on the
northwestern (higher elevation) portion of the site and greater than 10 feet bgs on the
southeastern (lower elevation) portion of the site. The nearest surface water bodies are the
Pace-Homer Ditch located approximately 200–250 south and southeast of the southeastern
site boundary, and Silver Creek located approximately 350–500 feet south and southeast of
the southeastern site boundary.
5.2 Spatial Distribution of Contaminants of Concern
Metals impacts exceeding screening levels and background concentrations appear to be
limited to imported fill soils in Zone 1 and Zone 2. Contaminated fill soils in Zone 2 may
have been imported prior to PCMC’s acquisition of the site (Section 3.1). Areal distribution
of contaminated fill soils are presented in Exhibit 2 and Exhibit 3.
Zone 3 UCL95s and UCL95 substitutes (Section 3.3) indicate that subsurface native soils in
Zone 1 and Zone 2 have not been impacted by leaching from overlying non-native
contaminated soils. Thus, the vertical distribution of contaminants of concern is limited to
imported contaminated soils present in Zone 1 and Zone 2.
5.3 Environmental Concerns Verification
5.3.1 Heavy Metals-Impacted Soil
Heavy metals-impacted soil has been confirmed to exist at concentrations that are above
applicable regulatory standards at concentrations that require corrective action. Heavy
metals-impacted soil present at the site is known to have been intentionally imported to the
site
5.3.2 Heavy Metals-Impacted Groundwater
Soil metals concentrations in native soils beneath imported contaminated fill soils do not
indicate that metals may have leached from overlying contaminated soils in sufficient
quantities to have potentially impacted groundwater. Reported metals concentrations in
subsurface native soils in Zone 1 and Zone 2 are consistent with background concentrations
present in Zone 3 samples. Further, the presence of clayey soils and shallow bedrock
Site Characterization Report
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities |Environmental | Geotechnical | Materials 17
(Section 5.1) indicates that infiltration of precipitation to groundwater may be limited at the
site.
5.3.3 Remedial Goals
PCMC’s remedial goal for the site is achievement of DWMRC risk-based closure criteria.
PCMC anticipates that all imported contaminated soil will be removed and disposed of off-
site. If post-removal confirmation samples indicate the presence of any residual impacts
they will be addressed through DWMRC’s risk-based closure process.
A full Risk Evaluation is presented in Appendix E. Risk calculations indicate that:
contaminated imported fill soils present in Zone 1 and Zone 2 present excessive
risks that require corrective action to achieve risk-based closure per Utah
Administrative Code R315-101-5
background cancer risk at the site for potential residential receptors exceeds 1x10-6
due to elevated background concentrations of arsenic.
5.3.4 Informational Data Gaps
The SCW identified the following informational data gaps that required further assessment:
laboratory data for non-lead metals
soil metals concentrations in native soils beneath imported contaminated soils
background metals concentrations in native soils.
Terracon’s conclusion is that the sampling results described herein have sufficiently
addressed the informational data gaps identified in the SCW, and no remaining significant
data gaps exist.
6.0 Conclusion
The investigation results presented herein indicate that the nature and extent of metals
contamination in soil at the site has been sufficiently characterized. A Corrective Action Plan
(CAP) should be developed that addresses the impacts and risks present at the site. The
type of corrective action that would most adequately address the existing environmental
impacts and achieve PCMC’s goals for the site would be excavation and off-site disposal of
metals-impacted fill soils in Zone 1 and Zone 2. As fully detailed in the Risk Evaluation
(Appendix E), excavation and off-site disposal of metals-impacted fill soils in Zone 1 and
Zone 2 would reduce overall site risks to background levels.

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.

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.
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
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.
V The sample concentration is too high to evaluate accurate spike recoveries.

Exhibit 1 (Appendix A) presents the site location on a portion of the United States Geological
Survey (USGS) topographic map.
1.2 Background Information
The site was historically used primarily as open space. A portion of the site was used for
vehicle parking. The site was acquired by PCMC in multiple phases from 1996 through 2008.
Beginning in 2010 and with approval from the Utah Department of Environmental Quality
(UDEQ), Division of Environmental Response and Remediation (DERR) and acknowledgment
from the United States Environmental Protection Agency (EPA), PCMC utilized the site to
temporarily stockpile approximately 34,000 cubic yards of Bevill-exempt metals-
contaminated soil excavated from mining-impacted development projects throughout the
Park City area. PCMC anticipated that the site would be developed as a permitted repository
for metals-impacted soils with oversight from UDEQ’s Division of Waste Management and
Radiation Control (DWMRC), but PCMC has since revised its development plans for the site
and intends to remediate and redevelop the site for other purposes.
Two previous investigations have been conducted at the site. A field X-ray fluorescence
(XRF) survey was conducted by AMEC Earth & Environmental (AMEC) in September 2010.
Approximately 180 locations were sampled via XRF for arsenic and lead. AMEC’s XRF data
indicated that lead impacts exceeding EPA Regional Screening Levels (RSLs) for Residential
or Industrial use were largely confined to the soil stockpile, but that limited impacts were
present on the northern portion of the site near the site entrance road.

A second investigation was conducted by Gerhart Cole Inc (GCI) in 2016. GCI collected 48
soil samples from 36 test pits located throughout the site. The results from GCI’s
investigation were largely consistent with the results of AMEC’s XRF survey and displayed a
similar pattern of impacts.
Site Characterization Sampling
Site characterization sampling was conducted at the site in July 2023 to fully evaluate the
known and suspected environmental impacts from metals in soil. The site was divided into
three sampling zones and a combined thirty locations were sampled (sample locations B-1
through B-30,Exhibit 2), with two soil samples collected at each sample location.
Zone 1 consists of the soil stockpile. In Zone 1, at each sampling location one
sample was collected from the most impacted depth interval (as determined by field
XRF screening) and one sample was collected from native soils 6–12 inches beneath
the stockpile soils. Zone 1 samples were collected using a track-mounted direct-
push drill rig. Drilling depths varied according to the soil stockpile depth which
averages approximately 10 feet, but ranges from less than 5 feet to approximately
20 feet. Drilling was conducted in 5-foot increments as-needed to fully intercept
underlying native soils.
Zone 2 consists of the area near the site entrance where previous investigations
identified off-stockpile impacted soil. In Zone 2, at each sampling location one
sample was collected from near-surface soils (0–2 inches) and one sample was
collected from shallow subsurface native soils (6–12 inches). Zone 2 samples were
primarily collected via hand digging or hand auger. A limited number of Zone 2
samples were collected using a track-mounted direct-push drill rig where non-native
soils were present at depths that precluded hand digging or hand auger collection
methods. These locations sample locations are B-12, B-16, and B-17 (Exhibit 2).
Zone 3 consists of unimpacted native soil areas and Zone 3 sample results are
considered site-specific background concentrations for risk evaluation and screening
contaminants of potential concern (COPCs). In Zone 3, at each sampling location
one sample was collected from near-surface soils (0–2 inches) and one sample was
collected from shallow subsurface native soils (6–12 inches). Zone 3 samples were
collected via hand digging.
Constituent concentrations in soil were compared to EPA RSLs for Residential or Industrial
use and groundwater protection soil screening levels (Dilution Attenuation Factor 20 [DAF
20] SSLs).
Results of the Site Characterization investigation were as follows. See the full Site
Characterization Report for complete laboratory analytical results.

Site Investigation Conclusions
Based on the previous investigations and the current site characterization conducted at the
site, the nature and extent of metals contamination in soil has been sufficiently
characterized and defined.
Soil Contamination Evaluation:
Metals impacts exceeding screening levels and background concentrations appear to
be limited to imported fill soils in Zone 1 and Zone 2.
Zone 3 (background) 95% upper confidence limits (UCL95s) and UCL95 substitutes
indicate that subsurface native soils in Zone 1 and Zone 2 have not been impacted
by leaching from overlying non-native contaminated soils. Reported metals
concentrations in subsurface native soils in Zone 1 and Zone 2 are consistent with
background concentrations present in Zone 3 samples.
All calculated background metals concentrations in Zone 3 were below RSLs and
DAF 20 SSLs except for arsenic. Site-specific background concentrations of arsenic
in soil are estimated to range from approximately 12 mg/kg to 26 mg/kg. Arsenic
UCL95s for subsurface native soils in Zone 1 and Zone 2 are within the estimated
background range.
Barium is not elevated above background concentrations in otherwise contaminated
fill soils present in Zone 1 and Zone 2.

2.0 CONCEPTUAL SITE MODEL
Terracon prepared this Risk Evaluation using the EPA’s online RSL calculator (https://epa-
prgs.ornl.gov/cgi-bin/chemicals/csl_search) to evaluate the cumulative risk posed by metals
Risk Evaluation
Gordo Site | Park City, Utah
August 11, 2023 | Terracon Project No. 61227505
Facilities | Environmental | Geotechnical | Materials 7
present at the site in soil. The first step was to develop a Conceptual Site Model (CSM),
which is used to document the potential for exposure to chemicals at the site based on the
source(s) of contamination, the release mechanism(s), potential routes of exposure (ROE),
representative concentrations of contaminants of interest (COI), and receptors (i.e.,
property occupants) in order to evaluate site-specific risks associated with the COIs
remaining. A graphical representation of the CSM is presented as Exhibit 3 (Appendix A). It
is important to bear in mind that the CSM assumes residential land use with complete
exposure pathways and no controls for exposure to impacted site media, and thus provides
a highly conservative evaluation.
The objective of the Risk Evaluation was to evaluate whether impacted soils on-site are
contaminated to the extent they pose a human health risk at levels above target maximum
risk levels and hazard indices. Concentrations of COIs in soils were first compared to the
EPA’s RSL Generic Tables and Dilution Attenuation Factor 20 (DAF 20) soil screening level
concentrations as requested by DWMRC.Concentrations of individual COIs in soils exceed
these screening levels specific to those individual COIs. In addition, the concern existed that
the cumulative effect of all the remaining COIs would present a risk that exceeded the
acceptable target excess carcinogenic risk of 1x10-6 and non-carcinogenic hazard quotient of
1.0. To evaluate the cumulative risk, Terracon utilized EPA’s RSL Calculator to evaluate the
calculated UCL95s and UCL95 substitutes for COIs present on-site. The following
subsections describe the key elements and aspects of the Risk Evaluation.
2.1 Sources, Release Mechanisms, and Affected Media
Bevill-exempt metals-contaminated soil excavated from mining-impacted development
projects throughout the Park City area were purposefully imported to the site by PCMC.
PCMC anticipated that the site would be developed as a permitted repository for metals-
impacted soils. PCMC has since revised its development plans for the site and intends to
remediate and redevelop the site for other purposes. Metals COIs for soil are listed in Table
1 (Appendix B). Smaller quantities of metals-impacted soils also appear to have been
imported to the site prior to PCMC’s acquisition of the site.
2.2 Receptors and Routes of Exposure
The site is currently undeveloped and minimally used by PCMC. The future use of the site is
expected to be mixed-use with potential residential, commercial, and transit hub
development. Subsurface excavation and construction is likely to occur at the site in the
near future as PCMC plans to develop the site. In order to be conservative, this Risk
Evaluation uses residential land use to represent the potential residential receptors. The
following routes of exposure were evaluated in this Risk Evaluation.

Facilities | Environmental | Geotechnical | Materials 8
Soil Routes of Exposure: Ingestion of soil and dermal contact with soil are the routes of
exposure considered for soils in the Risk Evaluation. To provide a conservative evaluation
regarding exposure risks, all routes and potential receptors (residential, indoor worker, and
construction worker) were included in the Risk Evaluation.
2.3 Chemicals of Interest (COI)
Soils
COI were identified as those metals reported above background UCL95s calculated from
Zone 3 sampling results. All RCRA 8 metals except barium were reported in soil above
background UCL95s in at least one sampling zone and depth interval. The list of COIs for
soil and the respective UCL95s and UCL95 substitutes are presented in Table 1 (Appendix
B).

4.0 ECOLOGICAL RISK ASSESSMENT
No surface water bodies are located on the site or adjoining properties. The future use of
the site is potentially mixed-use commercial, residential, and transit hub uses. As such, the
site will not be a viable habitat and will not be used by potential ecological receptors as a
habitat. Per Utah Administrative Code R315-101-5(j)(3), an Application for a Waiver of an
Ecological Risk Assessment has been prepared and is included as Appendix D.

5.0 CONCLUSION
This Risk Evaluation for the Gordo site evaluated the cumulative risk posed by reported
metals concentrations in site soils. The risk evaluation results indicate the following:
Metals concentrations in imported contaminated fill soils in Zone 1 and Zone 2
present a risk to future residential or commercial receptors at the site.
Metals concentrations in underlying native soils in Zone 1 and Zone 2 are
approximately equivalent to background metals concentrations in Zone 3. If
imported contaminated fill soils in Zone 1 and Zone 2 were removed, these
underlying would native soils in Zone 1 and Zone 2 would present risks that are
comparable to current background risks in Zone 3.
Background risks (i.e., Zone 3) at the site for potential residential receptors exceed
a cancer risk of 1 x 10-6 and a non-cancer Hazard Index of 1.0 for children (but not
adults) due to elevated background concentrations of arsenic.
Thus, the overall conclusion of this Risk Evaluation is that excavation and off-site disposal of
imported contaminated fill soils in Zone 1 and Zone 2 would reduce overall site risks to
background levels. Any residual background risks present following excavation and off-site
disposal of imported contaminated fill soils in Zone 1 and Zone 2 could be managed through
the following means.
A site-specific Health and Safety Plan should be developed that would provide
construction workers with hazard awareness training and detail specific engineering
controls and personal protective equipment (PPE) requirements to mitigate potential
exposures during development of the site.
Following the completion of site development, the site will be managed per the
requirements of the Park City Soils Ordinance (Park City Municipal Code Section 11-
15-1). If required, site specific-institutional controls (i.e., a Site Management Plan)
could be implemented that outline continuing obligations and land use limitations
associated with the site to ensure that exposure pathways are incomplete for future
occupants and commercial workers and will protect the site from impacts remaining
at the site.

Application For A Waiver Of
An Ecological Risk Assessment
Application for a Waiver of an Ecological Risk Assessment
Gordo Site, Kearns Boulevard and Richardson Flat Road
Park City, Summit County, Utah
This application is being submitted to request a waiver for performing an ecological risk
assessment at the Gordo site, located at Kearns Boulevard and Richardson Flat Road, Park
City, Utah.
In accordance with the Utah Administrative Code (UAC) R315-101, site investigations must
include an evaluation of human health and ecological risk to support risk-based closure. An
ecological risk assessment is warranted when it has been determined that exposure
pathways are potentially complete for ecological receptors. A complete pathway consists of:
1) a source, 2) a mechanism of contaminant release, 3) a receiving or contact medium, 4) a
potential receptor population, and 5) exposure route. Of these five criteria, the most
fundamental is the fourth criterion. In order for a potential receptor population to exist, a
site must contain open areas that would allow plant growth and suitable habitat for wildlife.
The Gordo site is slated for redevelopment following remediation of the existing
environmental impacts. Following development, the site will be nearly completely paved and
developed. Significant areas of vegetation will not be present, and the site will not contain
suitable habitat for wildlife. Although it is possible that some species could casually be
present (such as birds resting in nearby trees or crossing the property), it is not plausible
that any receptor would forage, nest, or den on the Gordo property itself when development
is complete.
Since there will not be a potential receptor population present following completion of site
redevelopment, an ecological risk assessment is not deemed required at this facility and a
waiver for conducting a quantitative ecological risk assessment per R315-101.5.3(a)(8) is
requested.
