1.0 INTRODUCTION
On behalf of CTP DEV LLC (CTP DEV), Tetra Tech, Inc. (Tetra Tech) has prepared this Corrective Action
Plan (CAP) to present the corrective action for the former ABF Freight Leaking Underground Storage
Tank (LUST) conditions at 55 South Redwood Road, Salt Lake City, Utah (Site, Facility I.D. 4001342).
Two LUST conditions have been observed at the Site and have been designated by the Utah Department
of Environmental Quality (UDEQ), Division of Environmental Response and Remediation (DERR), as
historical petroleum Release FFQ from 1988, and recent discovery of petroleum Release OLX associated
with the closure of Tanks 4, 5, 6 and 7 on October 8, 2024. Because the environmental impacts
associated with these releases overlap historically and geographically, this CAP has been prepared to
address both releases concurrently to support CTP DEV’s planned cleanup and redevelopment of the
Site.
1.1 PURPOSE AND OBJECTIVE
This CAP describes the approach and methods selected to clean up the overlapping LUST conditions
from Releases FFQ and OLX. The DERR issued letters to CTP DEV dated November 18 and 26, 2024
pertaining to Releases OLX and FFQ, directing the performance of a subsurface investigation for Release
OLX and development of this CAP for Release FFQ; copies of these letters are included in the CAP as
Appendix A. CTP DEV proposes to complete a Site Characterization Work Plan and conduct the
supplemental investigation requested by DERR for Release OLX while DERR is reviewing this CAP,
which is designed to concurrently remediate the impacts from Releases FFQ and OLX. The further site
characterization for Release OLX will focus on data collection to differentiate between the two releases;
otherwise, significant site data has already been collected across the Site for more than 20 years.
The CAP has been prepared in accordance with the guidance from DERR, including the Corrective Action
Plan Guide, Non-Petroleum Storage Tank Trust Fund, Leaking Underground Storage Tank Sites, dated
October 1, 2017 and the Corrective Action Plan Guide, Petroleum Storage Tank Trust Fund Leaking
Underground Storage Tank Sites, dated June 14, 2017. Both guidance documents are referenced
because Release FFQ does not have Petroleum Storage Tank Fund (PSTF) coverage and Release OLX
has PSTF coverage. The releases overlap and will be addressed concurrently as discussed during the
CAP Meeting between CTP DEV, Tetra Tech, and DERR representatives on December 4, 2024. The
CAP presents the established cleanup levels required to complete the remediation and closure of the
LUSTs in cooperation with DERR. This CAP and changes to it will require approval by the DERR.
1.2 BACKGROUND
The Site is a former truck terminal slated for new development within the Power District master plan, a
100-acre new commercial and residential area in Salt Lake City, Utah. The location of the Site is shown
on Figure 1. The Site has served as a truck terminal with fueling operations since 1959, which pre-dates
the development of Utah’s underground storage tank regulations under Utah Administrative Code (UAC)
R311. The Site was operated with various underground storage tanks as presented on Table 1 below,
with most tanks being closed by removal or in-place closure by the prior owner National Warehouse
Investment Corporation (NWIC). However, Tanks 4, 5, 6, and 7 had not been closed by NWIC prior to the
purchase of the Site property by CTP DEV on January 4, 2024. These four tanks were operated by ABF
Freight from 1990 until it vacated the site in approximately May 2023. These tanks were subsequently
closed by CTP DEV on October 8, 2024. Figure 2 shows the approximate locations of the Underground
Storage Tanks (USTs).

Table 1 Site Underground Storage Tank Summary
Petroleum Release FFQ was reported in 1988 and according to DERR records accounted for multiple
historical releases of underground storage tanks (USTs) and related product piping. A study conducted by
forensic chemists Friedman and Bruya (F&B) of Seattle, Washington on behalf of NWIC, dated March 30,
2000, states that there were multiple releases from 1959 to 1988. Specifically, they cited six documented
releases as listed below on Table 2. A Copy of the Friedman and Bruya report is included with this CAP
for informational purposes as Appendix E.

Table 2 Site Petroleum Release History
Friedman and Bruya estimated that the total volume for Release FFQ was between 97,000 to 214,000
gallons, primarily diesel. The quantity released from the gasoline UST (UST I.D. 11) was unknown and
not included with the above quantities. USTs 8, 9, 10, and 11 were closed and removed. No releases
were reported for USTs 8, 9, and 10. USTs 1, 2, 3, 12, 13, and 14 were closed in place. USTs 1, 2, and 3
are beneath the floor of the former Fueling Building, and USTs 12, 13, and 14 are located under the
asphalt on the east side of the former Fueling Building. There were significant releases from UST 1, 2, 3,
12, 13, and 14 according to the F&B report. It also appeared to F&B that USTs 4, 5, 6 and 7 leaked
before 1988 and subsequent UDEQ tank inspection records (i.e., inspections showed staining in the tank
fill ports); however, these tanks continued to be operated by ABF Freight with likely releases until ABF
Freight vacated the Site in approximately May 2023. These tanks were subsequently closed by removal
by CTP DEV on October 8, 2024.
In response to the presence of historical releases, a groundwater recovery trench and water treatment
facility were installed at the northwest corner of the property in 2001. The purpose was to intercept diesel
light non-aqueous phase liquid (LNAPL) and preclude migration off the property. The trench extends from
the northwest corner traversing south and east a combined 600 feet along the property boundary at this
downgradient corner of the property. The trench was coupled to a 16-inch diameter well where a
downhole electric pump recovered water and an LNAPL pump skimmed petroleum liquids. The recovered
water and petroleum mix was treated by oil-water separation and the water was discharged under a
permit to the Salt Lake City Water Reclamation Facility (SLCWRF). Since startup of the remediation
system in 2001, approximately 22,000 gallons of free product (light non-aqueous phase liquid, LNAPL)
are reported to have been recovered and over 11 million gallons of groundwater treated and discharged
to the SLCWRF sanitary sewer.
A free product skimming system manufactured by Xitech, was installed in three wells within the former
Fueling Building in 2012 or 2013. The skimmers were placed in wells EXT-B, EXT- C and EXT-D.
In 2006, additional corrective action was performed by Atlas Technical Consultants (Atlas) on behalf of
NWIC to remove source material by soil excavation. Since then, there have been six additional soil
excavations. These occurred in 2007, 2010, 2013, 2014, 2019, and 2020. An estimated 6,000 cubic yards
of impacted soil were removed from the Site and disposed of at E.T. Technologies Soil Regeneration

2.0 SITE CHARACTERIZATION AND CURRENT CONDITIONS
This CAP is based on existing Site data that have been previously collected by Tetra Tech, Atlas, and
others performing work for the former owner of the property. A summary of these conditions is presented
in this section, which supports the basis for corrective action alternatives evaluation and remedy selection
as presented in Section 3, and the basis for corrective action design presented in Section 4.
The Site is bordered by Redwood Road to the west, South Temple Street to the north, and Rocky
Mountain Power (RMP) which includes a power generation facility, and a laydown yard, east and south
respectively. The typical soil encountered in past Site investigations and corrective action soil excavations
consists of clayey silts to a depth of approximately 11 feet below ground surface (bgs), underlain by clean
sand. Past use of the Site was a historic landfill from the late 1800s to the early 1900s, which is known as
the South Temple Landfill. Remnants of municipal waste have been encountered in shallow subsurface
soils across the Site at depths ranging from approximately 1 to 6 feet bgs. Also, the Site has undergone
corrective action that has involved the removal and disposal of petroleum impacted soil as described in
Section 1.2. Replacement soils placed in the excavations consisted of pea gravel, creating pockets of
high permeability zones. The excavation areas are within the former Fueling Building and areas west and
north of the former Fueling Building. Figure 2 shows past excavation areas. The previous soil
excavations were performed piecemeal as they were excavated while the freight terminal was an active
trucking facility.
2.1 REGULATORY REQUIREMENTS
According to Utah Administrative Code (UAC) R311-211-6, the “Petroleum Storage Tank (PST) Facility
Cleanup Standards,” incorporate by reference the DERR’s Initial Screening Levels (ISLs) table dated
November 1, 2005, which lists screening levels for PST sites. If the DERR Director determines that a
release from an UST has occurred, the Director shall evaluate whether the contamination at the site
exceeds ISLs for the released constituents. The Director may then require owners and operators to
submit information that DERR believes will assist in making this evaluation. If all impacts are below initial
screening levels, the Director shall evaluate the site for No Further Action determination.
If impacts from a release are above the ISLs, the Director shall require owners and operators to submit
relevant information required to evaluate the site using the Tier 1 Screening Criteria. The Tier 1 Screening
Criteria were incorporated into the rule on November 1, 2005. Tier 1 screening criteria require that the
following conditions exist for use of these less conservative cleanup criteria compared to the ISLs.
1. No buildings, property boundaries or utility lines are located within 30 horizontal feet of the
highest measured concentration of any contaminant that is greater than the initial screening
levels but less than or equal to the Tier 1 screening levels.
2. No buildings, property boundaries or utility lines are located within 30 horizontal feet of the
highest measured concentration of any contaminant that is greater than the initial screening
levels but less than or equal to the Tier 1 screening levels.
3. No water wells or surface water are located within 500 horizontal feet of the highest measured
concentration of any contaminant that is greater than the initial screening levels but less than or
equal to the Tier 1 screening levels.
If Tier 1 Screening Criteria are met, the Director shall evaluate the site for No Further Action
determination. If any of the Tier 1 Screening Criteria are not met, owners and operators shall conduct a
site investigation to provide information to the DERR regarding the factors outlined in Subsection R311-

6 February 14, 2025
211-5(3) and 40 CFR Part 280, which has already been completed for the Site except as described in
Section 1.1 for the OLX Release.
Upon completion of the site investigation, the owners and operators may propose that the ISLs or Tier 1
Screening Criteria be used for corrective action standards or may propose for evaluation and approval of
the DERR, alternative (less stringent) site-specific cleanup standards based upon an analysis of the
factors outlined in Subsection R311-211-5(3). CTP DEV currently proposes use of the ISLs established in
Subsection R311-211-6(1) as the site-specific cleanup standards but may elect to consider alternative
cleanup standards based on the outcome and effectiveness of CAP implementation.
2.2 PAST INVESTIGATIONS AND REMEDIATION
Tetra Tech performed a Phase I Environmental Site Assessment (ESA) for the Site beginning in August
2023 to support environmental due diligence phase for purchase of the property by CTP DEV. The Phase
I ESA provided a summary of Site environmental conditions and identified a Recognized Environmental
Condition (REC) and one Historical REC (HREC) as defined by ASTM Standard E 1527-21. These
conditions are copied from the Phase I ESA Report dated October 27, 2023, and presented below for
background information purposes.
• REC - The Subject Property is undergoing corrective action due to a diesel release from the on-
site Fueling Building, underground storage tanks and/or ancillary piping. The release is identified
as Leaking Underground Storage Tank Site (LUST) “FFQ” with the State of Utah Department of
Environmental Quality, Division of Environmental Response and Remediation (DERR). The
facility identification number is 4001342. Ongoing cleanup efforts began in 2001 with a dedicated
free product recovery system. As of 2019, approximately 20,500 gallons of diesel had been
recovered. Recent reports indicate that considerable free product continues to exist in the
western third of the Subject Property. It is Tetra Tech’s understanding from discussions with
Atlas, the consultant for [NWIC], that free product recovery within the Fueling Building is ongoing.
• HREC - The Subject Property is listed under CERCLIS for the South Temple Street Landfill.
Review of the DERR documents shows the South Temple Street Landfill as having an address of
1407 West North Temple. The landfill operated from 1895 to 1930 and accepted municipal and
industrial waste. The address places the CERCLIS site approximately 1000 feet northeast from
the Subject Property. The approximate size of the landfill was 175 acres; and the Subject
Property appears to have been part of the landfill property, or at least have overlapping
boundaries. The landfill was given a no further action status based on investigative activities and
contaminant levels that were at or below U.S. Environmental Protection Agency (EPA) Regional
Screening Levels (RSLs). Prior investigation and remedial action on the Subject Property
consisting of soil excavation on the Subject Property, encountered non-engineered fill and is likely
present along with deleterious materials consisting of municipal wastes at select locations within
the boundaries of the Subject Property.
Tetra Tech performed a Phase II ESA and completed a Phase II ESA Report dated October 27, 2023 on
behalf of CTP DEV to further evaluate the UST release and South Temple Landfill. Findings from that
investigation verified the presence of LNAPL across the western part of the Site, and related petroleum
hydrocarbon impacts to soils around former LUSTs and downgradient from the LUSTs and Fueling
Building. Elevated arsenic in soil and groundwater was also observed at select location that exceeded
EPA RSLs for residential and industrial land use. Seven of the 14 soil samples exceeded the EPA
Industrial RSL of 3 mg/kg for arsenic; and all values (even non-detect samples with detection levels
limited to 2.12 mg/kg or higher), exceeded the EPA Residential RSL of 0.68 mg/kg. However, the
naturally occurring, background concentration for arsenic in Utah soils has been observed to exceed the

7 February 14, 2025
RSLs and can range from 15 mg/kg and higher depending on location. Therefore, the presence of arsenic
at the Site is considered naturally occurring at the concentrations identified during the Phase II ESA.
In 2024, on behalf of CTP DEV, Tech Tech began operation and maintenance of the remediation system.
As part of the weekly operations, a few select wells were gauged for depth-to-water and depth-to-product.
Wells that showed significant product thickness were bailed to remove the diesel. Quarterly depth-to-
water and depth-to-product measurements were made on a larger set of wells, continuing with the same
wells that Atlas was previously gauging for NWIC. Quarterly events were performed in March, July, and
September 2024; and an annual groundwater sampling event was performed at the end of October, and
the beginning of November 2024, which included additional depth-to-water and depth-to-product
measurements. Results from the gauging of the wells and analytical results from the sampling are
discussed in the next section of this report
The Xitech free-product recovery system failed in March 2024, presumably from a voltage surge, and was
taken out of service at that time. The perimeter groundwater recovery system continued to operate until
early October 2024 when the power to the property was terminated by Rocky Mountain Power in
anticipation of building demolition at the Site. The total product recovered by the system was estimated to
be approximately 20,700 gallons. Following system termination, the groundwater recovery sump in the
remediation building was grouted to the top of the water column in preparation for Site demolition and the
corrective actions described in this CAP.
2.3 GROUNDWATER MONITORING 2024
Water levels and LNAPL, if present, were measured at all existing on-site and off-site monitoring wells
accessible and in good repair that are associated with the Site. Fifty-three wells were gauged in March,
June, and September 2024. Fewer wells were gauged in October 2024, because some wells were not
accessible due to a homeless population trespassing on the Site. Depth-to-water and depth-to-product
measurements were performed using an electronic oil-water interface probe accurate to 0.01 feet. Tables
1, 2, 3, and 4 provide depth to water and depth to product measurements for March, June, September,
and October 2024. Figures 4, 5, 6, and 7 show groundwater contour elevations for each monitoring
event. Groundwater elevations were corrected for wells with measurable product thicknesses. Figures 8,
9, and 10 show LNAPL thicknesses in March, June, and September 2024 across the Site. No LNAPL
thickness map was prepared for October because of the accessibility issue described above and the
absence of data especially from within the Fueling Building where the homeless populations was
encamped.
In general groundwater flow is to the northwest, consistent with previous years. Hydraulic gradients were
estimated between monitoring wells W-4 and W-21 for each event. The hydraulic gradient showed little
change between events with a gradient of 0.011 measured in March and 0.012 measured in June,
September, and October 2024.
The LNAPL thickness measurements show the LNAPL plume to be thickest within the footprint of the
former Fueling Building and then tapering toward the northwest corner of the property. Perimeter wells W-
20, W-21, W-9, and RW-A showed LNAPL was present during each monitoring event. However, LNAPL
was not observed in any of the off-site wells.
2.3.1 Groundwater Sampling
Tetra Tech performed groundwater sampling on October 28, 31, and November 1, 2024. Water levels
and LNAPL, if present, were measured at all existing on-Site and off-Site prior to any purging and
sampling as previously discussed. Monitoring wells sampled were HD-6, HD-4, HD-1, W-19, W-M, RW-4,
MW-7, W-11, W-3, W-F, MW-H, W-25, W-27A, HI-SW, W-22, W-23, W-24, and MW-3. Wells were not

sampled if LNAPL and/or a heavy sheen were identified in the well during the well gauging or purging
efforts, and the presence of these conditions was recorded and reported with the sample results.
Samples were collected using disposable polyethylene bailers. Chemical-resistant gloves were worn by
field staff during sample collection and replaced between sample locations to minimize potential cross-
contamination.
Wells were purged a minimum of three well casing volumes before sample collection. Purge water from
the wells was thin spread on the asphalt away from property lines or storm grate intakes. The following
decontamination procedures were used for non-disposable groundwater sampling equipment.
• Rinse with distilled water
• Wash and scrub with environmental detergent and distilled water
• Rinse with distilled water
• Wipe and air dry.
Reasonable efforts were made to use disposable or dedicated field equipment. All reusable sampling
equipment (e.g., interface probe and water level indicator) were decontaminated as described above prior
to beginning field sampling, between sampling locations, and at the completion of field activities.
The person collecting the samples was responsible for sample custody from the time of sample collection
to receipt by a laboratory or until samples were shipped. A sample is considered under custody if one of
the following conditions applies:
• The sample is in a person’s possession
• The sample is in that person’s view after being in his or her possession
• The sample was in that person’s possession and then placed in a secured location
• The sample is in a designated secure area.
A Chain-of-Custody Record with its assigned sample numbers accompanied all samples to the laboratory.
When samples were shipped, custody seals were attached to each cooler to ensure that tampering with
the samples did not occur in transit, and the shipment air bill became part of the Chain-of-Custody
documentation.
2.3.2 Summary of Groundwater Analytical Results
The groundwater sample results for which constituents were detected in one or more samples are
presented on Table 5. The results are compared against the following screening criteria:
• Initial Screening Levels developed by DERR as conservative, preliminary evaluation criteria for
petroleum hydrocarbon constituents associated with LUST sites.
• Tier 1 Screening Criteria developed by DERR, which are less conservative than ISLs and can be
applied to LUST sites for evaluation and cleanup under the specific geographical criteria specified
by DERR and presented in Section 2.1.
All groundwater sample results were below the applicable screening criteria listed above and shown on
Table 5 except for total petroleum hydrocarbons (TPH) as diesel (DRO). Samples from on-site wells MW-
H (24.8 mg/L) and HD-4 (10.4 mg/L) exhibited concentrations of TPH-DRO exceeding the groundwater
Tier 1 level of 10 mg/L. Other wells sampled on-site were above the ISL of 1 mg/L for TPH DRO except
for HD-1 which was below. Off-site wells W-25 and W-27A, located across Redwood Road, and W-24,
located north of South Temple Street were below the ISL. Wells HI-SW, W-22, and W-23, located on the
north side of South Temple Street, north of the northwest property corner were above the ISL but below
the Tier 1 level. Figure 11 shows the TPH DRO values for the sampled wells.

2.4 UST CLOSURE
On January 4, 2024, the Larry H. Miller (LHM) group purchased the former ABF Freight property from
NWIC with the intent to re-develop it as a new commercial property within The Power District. As part of
the redevelopment, all buildings that were on the property have been razed. USTs 4, 5, 6, and 7 were
removed on October 8, 2024. Based on the results of the closure samples, visible evidence of soil
staining in the UST excavation, and the presence of diesel LNAPL on the water surface, there was a
release from the UST system consisting of these tanks. Confirmation soil and groundwater sample
analytical results confirm that significant impacts to both soil and groundwater exist near these former
tanks. Tables 6 and 7, respectively, summarize the soil and groundwater results for the samples
collected following the UST removals. Appendix B presents select photographs taken during the UST
removal showing impacts to soil and groundwater and staining on the tanks. Appendix C presents the
analytical report for the UST closure samples. Based on these results and submittal of the UST Closure
Report to the DERR by Spackman Enterprises, which performed the UST removal work, DERR issued
the letter for Release OLX dated November 18, 2024, as described previously in Section 1.1.

10 February 14, 2025
3.0 CORRECTIVE ACTION COMPARISON AND SELECTION
As discussed during the CAP Meeting on December 4, 2024, with attendance from CTP DEV, Tetra
Tech, and DERR, CTP DEV plans to perform the additional corrective action described in this CAP after
consideration of a range of alternatives, prior Site remediation experience, and improved access to the
subsurface resulting from CTP DEV’s planned Power District development. The planned approach
consists of additional source removal through soil excavation and LNAPL recovery, which is the most
aggressive remedial alternative considered. Recommendation of this remedy was based on Tetra Tech’s
evaluation of three potential corrective actions as described in this section. CTP DEV has proceeded to
prepare this CAP, corrective action design drawings, and supplemental materials per DERR’s
requirements as described in the remaining sections of this CAP.
3.1 MONITORED NATURAL ATTENUATION
Monitored natural attenuation (MNA) was evaluated and determined to be insufficient to achieve
regulatory requirements and CTP DEV’s Site redevelopment objectives within a reasonable time. The
release size estimated by F&B in 1988 was between 97,000 to 214,000 gallons, and only 20,700 gallons
of free product are estimated to have been recovered to date through the existing recovery systems (not
accounting for product removed through soil excavations). Tetra Tech believes that too much free product
and absorbed product in soil near the fluctuating water table exists for meaningful degradation and MNA
to be effective or efficient for this Site. It is expected that following more aggressive mass removal as the
selected corrective action that MNA will occur in the groundwater to achieve regulatory requirements for
Site closure.
3.2 OPERATION OF PUMPING SYSTEMS
Continuing operation of the existing product and groundwater recovery systems, and augmentation with
additional pumping systems, were considered and determined to be ineffective to achieve regulatory
requirements and CTP DEV’s Site redevelopment objectives. The existing remediation system was
designed by Montgomery Watson with DERR approval on April 28, 2000. The system was designed to
recover LNAPL at the northwest corner of the property for the specific purpose of preventing LNAPL from
migrating off Site; and the system has fulfilled this objective effectively. However, the system was not
designed to remediate impacted soils or recover free product within the interior of the plume. The addition
of more pumping wells, trenches and sumps would reduce the time requirement for product recovery, but
this approach will not address the presence of hydrocarbon-stained soil at the water table (i.e., smear
zone), which will continue to impact shallow groundwater for a long time. Therefore, continued operation
and build-up of the pumping system will not satisfy the corrective action objectives nor meet CTP DEV’s
Site redevelopment objectives.
3.3 SOIL EXCAVATION AND PRODUCT RECOVERY
Because CTP DEV has purchased the property and intends to redevelop it for mixed commercial and
residential use, the existing structures will be removed providing an opportunity to access and remove
impacted soil and LNAPL directly. This corrective action approach could not be performed previously
while ABF Freight was operating the Site as a truck terminal, except for small, disconnected areas where
excavations and product removal could be performed; these efforts proved effective but with limited
overall effectiveness because the entire mobile product plume could not be address.

11 February 14, 2025
After Site demolition, asphalt and concrete will be removed in phases from the excavation area, and clean
overburden soil will be removed and staged away from the excavation area. Because the excavation area
is so large, the excavation will be performed in segments (or “cuts”) as further discussed in Section 4.
Impacted soil will be excavated and properly disposed of at a pre-approved landfill like prior soils
selectively excavated and removed from the Site. During the excavation and following soil removal,
LNAPL will be skimmed from the water surface, collected in a vacuum tanker truck, and hauled off Site for
separation, treatment, and disposal. Figure 10 shows the estimated extent of the LNAPL plume based on
product thickness measurements taken on September 26, 2024. The area to be excavated will generally
cover the plume extent with possible limitations on the north and west sides of the plume where the actual
extents of LNAPL migration are expected to coincide with the existing recovery trench. Section 4 and the
corrective action drawings referenced therein provide additional details regarding this selected corrective
action.

12 February 14, 2025
4.0 CORRECTIVE ACTION DESIGN AND CONSTRUCTION DETAILS
The selected remedy to effectively address both Releases FFQ and OLX is soil excavation and LNAPL
recovery. This corrective action will build upon the previous soil and free product removals at the Site and
consist of sequential excavation of areas containing impacted soil and LNAPL.
The following corrective action Design Drawings, included with this CAP, present details of the project
boundaries, existing monitoring wells, excavation limits, corrective action process, LNAPL recovery, and
partial backfilling of the excavation for support the work:
• Drawing G-001 Cover Sheet
• Drawing C-100 Existing Conditions Plan
• Drawing C-101 Corrective Action Design Plan
• Drawing C-102 Excavation and Backfill Plan
• Drawing C-103 Excavation and Backfill Sections
• Drawing C-104 Details
4.1 SCOPE OF CORRECTIVE ACTION
The primary activities and objectives for this corrective action are listed below, and the paragraphs that
follow elaborate on these activities. CTP DEV will retain a remediation contractor with DERR UST Closure
Certification (Contractor) to perform most of the work (including all work associated with managing
petroleum impacted soils). Tetra Tech will provide field oversight and direction as the Engineer
representing CTP DEV through completion of the work and UST closure reporting.
• Conduct a Job Hazard analysis and develop a project-specific Health and Safety Plan.
• Mobilize and prepare for Site work, including establishment of stormwater pollution prevention
measures, excavation areas, haul routes, staging areas, and equipment and worker parking
areas.
• Excavate approximately 38,300 cubic yards (cy) of soil to remove clean overburden soil and
expose the LNAPL layer and smear zone containing residual diesel fuel and other petroleum
constituents for removal and off-site disposal, as described in subsequent bullets.
• Segregate relatively clean (i.e., petroleum-free) overburden soil and backfill placed in prior
excavations for on-site staging and future use as backfill soil.
• Load, haul, and transport petroleum-impacted soil for disposal at the Salt Lake Valley Landfill in
accordance with landfill requirements for acceptance of petroleum impacted soil.
• Place approximately 11,200 cy of clean aggregate (or crushed concrete) to subdivide the
excavation cuts for subsequent LNAPL removal and groundwater treatment with the aggregate
berms providing vehicle access into the excavation.
• Remove LNAPL from the groundwater surface using a vacuum truck and high-pressure water
equipment to extract free product (plus limited groundwater) for off-site separation, treatment, and
disposal.
• Enhance groundwater treatment within the open excavation if required to achieve applicable
cleanup criteria (e.g., air sparging and/or chemical treatment).
• Monitor groundwater within the open excavation and retained monitoring wells to demonstrate
achievement of applicable cleanup criteria.

13 February 14, 2025
4.2 CORRECTIVE ACTION DESCRIPTION
Existing Site conditions are shown on Drawing C-100, including the locations of historical ABF Freight
operations as they existed prior to recent building demolitions performed from December 2024 to January
2025. This drawing shows property boundaries, approximate elevation contours, the estimated LNAPL
plume boundary, and the perimeter LNAPL recovery trench location in the northwest corner. The notes on
this drawing present the requirements for Contractor site preparation activities and field engineering to be
provided by the Engineer.
Drawing C-101 shows the general Corrective Action Design Plan, including the estimated extents of the
excavations, which encompass the LNAPL Plume but have been squared to facilitate phased, sequential
excavation of the impacted soils. This plan shows the estimated division of the corrective action work
relating to the larger, non-PSTF, Release FFQ on the north side of the Site and the smaller, PSTF,
Release OLX on the south side of the Site. The approximate proportion for these areas is two-thirds for
the non-PSTF area and one-third for the PSTF area, which will be validated through the forthcoming site
investigation described in Section 1.1 and upon agreement with the DERR. This plan presents the project
area boundaries, Site ingress and egress, general excavation directions, soil erosion and sedimentation
controls (SESCs), and the planned clean overburden stockpile area.
Details for the excavation and backfilling process are presented on Drawing C-102, which shows the
sequential order recommended for Contractor cuts beginning in the northwest corner of the property at
“Cut 1” and sequentially excavating Cuts 1 through 18, until the excavation is complete, and all
petroleum-impacted soil has been removed. Coarse aggregate backfill consisting of imported rock or
crushed concrete (if available) will be used to systematically stabilize the excavation cuts and develop
through roads for access to the water table for LNAPL removal, water treatment, and monitoring. Drawing
C-103 shows the cross-sections referenced on Drawing C-102, which complement the plan drawing
showing the design depths of excavations and lines and grades for placement of the aggregate backfill.
The notes on Drawings C-102 and C-103 present details on the excavation sequencing, aggregate
backfill, berm construction, and LNAPL removal.
The excavation limits to the west and north near the northwest corner of the property are the LNAPL
recovery trench or property lines, depending on the extent of visible petroleum staining in the soil.
Excavation boundaries to the south and east will be determined in the field based on visual observations,
field screening with a photoionization detector (PID), and soil analytical testing for excavation side-wall
samples as described in Section 4.1. The actual excavations boundaries may be shorted in areas such as
planned Cut 12, if visible petroleum staining or LNAPL are not observed west all the way to the property
boundary. It is noted that RMP has a new laydown yard on part of the former ABF Freight property that
forms a boundary to the east of the proposed corrective action work area. Based on available data, the
excavation is anticipated to be terminated west of the RMP laydown area.
The total excavation depth will terminate at 11 feet bgs, based on field observations and direction from
the Engineer. Previous excavations performed by Atlas revealed that the bulk of diesel residuals
terminates at 11 feet and deeper excavation depths encountered loose clean sands that resulted in rapid
water influx and unstable excavation conditions. The Design Drawings conservatively show a maximum
excavation depth of 12 feet, but actual excavations will be limited to the depth required to remove
petroleum impacted soil.
Depending on the actual extent of LNAPL and diesel-impacted soil, additional excavation may be
required at a future time north of the planned excavation extent beneath South Temple Street; however,
this is not currently anticipated and confirmation soil sampling and analysis as described in Section 4.1
will be used to verify the completion of lateral excavations in all direction around the LNAPL plume.

14 February 14, 2025
Excavated soils will be segregated into clean overburden soil for temporary stockpiling on Site and reuse
as excavation backfill upon completion of remediation. Petroleum impacted soil will be loaded directly into
trucks for transportation and disposal at an appropriate landfill facility as directed by the Engineer based
on existing analytical results. All analytical results collected to date indicate that the LNAPL and soils are
nonhazardous, petroleum-impacted (primarily diesel fuel), solid waste. Historical disposition of excavated
soils by NWIC and its contractor Atlas has been through the E.T. Technologies Soil Regeneration Site
(ETT) and the Salt Lake Valley (SLV) Landfill, which currently have adjacent operations and cooperate in
managing petroleum impacted soils. The ETT and SLV Landfill are the current designated location(s) for
disposal of the petroleum impacted soils, and the Engineer will coordinate with the operators at these
facilities to direct the impacted soils to the correct facility for treatment (i.e., ETT) and disposal (SLV
Landfill), as appropriate based on their requirements for petroleum impacted soil. The report to be
submitted following the site investigation for Release OLX will include supplemental results documenting
the absence of hazardous substances in samples collected during December 2024. However, because
the Site was historically part of the historical South Temple Landfill, the DERR has directed CTP DEV to
maintain an inspection and waste management plan as part of this CAP for management of potential non-
petroleum wastes if they are excavated during the work. Section 7 of this CAP presents this contingency
plan for unidentified waste and Drawing C-104 includes notes to the Contractor for unidentified waste
management procedures, as directed by the DERR.
After the aggregate berms for a few cuts have been established (e.g., Cuts 1, 2 and 3), the Engineer will
direct Sump and Trap LLC (STC) of Salt Lake City to mobilize appropriate equipment to the Site to
remove the LNAPL from the groundwater surface. The Contractor will facilitate access to the individual
cut sections where STC will provide a 5,000-gallon or smaller vacuum tanker truck to remove LNAPL.
STC will use a pressure washer to force LNAPL into the corners of each cut where it can use a vacuum to
recover the petroleum free product. Periodic visits by STC will be performed and access berms must be
constructed between the cuts as shown on Drawing C-102 and excavation cross-sections (Drawing C-
103) to provide ingress and egress into the excavations. STC will remove the LNAPL while making efforts
to minimize the amount of groundwater pumped by the vacuum trucks. The recovered liquids will be
transported to STC’s Woods Cross, Utah operation for separation, recovery of the product for beneficial
reuse, and permitted discharge/disposal of the removed water.
Upon completion of the soil excavation and off-site disposal, and the LNAPL removal, CTP DEV and the
Engineer will assess the residual presence of petroleum hydrocarbon constituents in the shallow
groundwater exposed within the open water ponds. Assessment of the on-site groundwater will be
performed as described in Section 8, Groundwater Monitoring Program. It is anticipated that upon
removal of the petroleum sources in the soil and LNAPL that dissolved constituent concentrations in the
groundwater will also dissipate over time. The open excavations with ponded water will be secured by the
existing perimeter fence to prevent potential human exposures, and if necessary, deterrents such as
sound devices or predator decoys will be placed around the ponds to deter birds from inhabiting them.
The ponds will remain open as long as Site development allows to facilitate natural aerobic
biodegradation of dissolved petroleum constituents. CTP DEV will also consider the application of air
injection or chemical additives to the pond water surfaces to enhance the biodegradation, depending on
the results of groundwater monitoring.
Through implementation of this corrective action, secondary source materials consisting of LNAPL, and
petroleum impacted soils with the highest concentrations of petroleum hydrocarbons will be removed.
These actions will protect human health and the environment, minimize potential future degradation of
groundwater, and reduce potential future worker exposures to achieve the risk-based requirements for
construction workers and future land users, and thus achieve the DERR requirements for LUST closure.

15 February 14, 2025
4.3 SOIL CONFIRMATION SAMPLING
The Engineer will collect confirmation soil samples around the excavation perimeter sidewalls. It is
proposed that samples be collected from the sidewalls at a depth within the vadose zone or approximately
1 foot above the current depth to groundwater (i.e., approximately 6-7 feet bgs). Samples will be collected
every 200 linear feet to document residual petroleum concentrations that remain following soil excavation.
No samples from the excavation floor are planned at this because the excavation floor will be at a depth of
approximately 11-12 feet bgs, and previous excavations found that impacts did not extend below this depth
and further assessment of residual impacts with depth will come from groundwater analysis.
The side-wall soil samples will be field screened for visual petroleum staining and for volatile organic
compounds (VOCs) using a photoionization detector (PID) to document the field conditions of the samples.
Samples will be collected in laboratory-supplied containers and analyzed by a Utah Certified Laboratory for
benzene, ethylbenzene, toluene, total xylenes, naphthalene (BTEXN) by EPA Method 8260 and TPH-DRO
by EPA Method 8015.
All field documentation, use of the PID, equipment decontamination, and soil and groundwater sampling
shall follow the Tetra Tech Standard Operating Procedures presented in Appendix F.

16 February 14, 2025
5.0 PERMITTING REQUIREMENTS
Implementation of this CAP will require correspondence and potential permitting through the following
agencies. This list is not all-inclusive, and all applicable local, state, or federal rules, codes, or laws will be
followed by CTP DEV, the Engineer, and the Contractor. Documentation of notifications, permits, or
approvals obtained from other agencies will be submitted to the DERR project manager.
5.1 DIVISION OF AIR QUALITY
As per UAC R307-309, any source 1/4 acre or greater in size is required to submit a Fugitive Dust Control
Plan (FDCP) to the Utah Division of Air Quality (UDAQ). The FDCP is required to help sources minimize
the amount of fugitive dust generated during excavation and trucking operations that will occur during
remedial activities. A FDCP will be prepared by the Contractor (with input by the Engineer) in accordance
with state regulations for delivery to the UDAQ.
Because petroleum vapors may be emitted into the atmosphere during the corrective action process, the
UDAQ will be notified and provided the required information to determine if the work can be done under
de minimis conditions, or if an air discharge permit or approval letter will be required. Because the
petroleum at the Site is primarily diesel fuel and not gasoline and the duration of the work is expected to
be limited to two to three months, the potential for vapors is low and an air discharge permit is not
expected to be required by the Engineer.
5.2 DIVISION OF WATER QUALITY
There are groundwater, surface water, or re-injection requirements for this project. If conditions change
and discharge to surface water becomes a requirement, proper permits will be obtained from the Division
of Water Quality before such actions.
5.3 DIVISION OF WASTE MANAGEMENT AND RADIATION CONTROL
Past use of the Site as a historical landfill presents the possibility of encountering soil and/or waste that
contains constituents other than petroleum. If this occurs, the procedures presented in Section 7, Non-
Petroleum Waste Management Plan, will be implemented and the DERR will be informed. It is expected
that DERR and CTP DEV will coordinate efforts with the Division of Waste Management and Radiation
Control if hazardous materials are encountered to ensure compliance with sample collection, permitting,
transportation, and disposal of such materials.
5.4 SALT LAKE COUNTY HEALTH DEPARTMENT
The Salt Lake County Health Department will be notified at least 72 hours before the commencement of
Field work related to the corrective action.
5.5 BLUE STAKES
Blue Stakes of Utah will be notified before the commencement of excavation activities related to the
corrective action for utility clearances.

17 February 14, 2025
6.0 PUBLIC NOTIFICATION
Prior to implementing the corrective action, the potentially affected public will be notified of the corrective
action plans and timing in accordance with UAC R315-124. Public notification is required to reach the
segment of the public that may be directly affected by the release or the corrective action process. Public
notice will be conducted by direct notification to adjoining property owners that could be affected. If
significant concerns are raised by affected individuals and/or businesses, a public meeting may be
necessary and will be coordinated with the DERR.
A copy of the proposed public notice is included in Appendix G. The public notice includes all
requirements outlined in the Public Notice Template published by DERR in the DERR Corrective Action
Plan Guide

18 February 14, 2025
7.0 NON-PETROLEUM WASTE MANAGEMENT PLAN
The past use of the Site as a historical landfill presents the possibility for soil and/or waste to contain
contaminants other than petroleum that may require characterization and special handling procedures for
proper disposal. This waste management plan establishes the procedures for characterization, on-site
handling and staging, and disposal to mitigate possible environmental hazards to human health and the
environment if conditions other than petroleum hydrocarbons are encountered during implementation of
the planned correction actions.
7.1 ASBESTOS CONTAINING MATERIALS
Given the historic use of the area for solid waste disposal, asbestos-containing materials (ACM) or
Transite® siding/piping may be encountered at this Site. If encountered, a Utah Certified Asbestos
Inspector will be available during excavation activities to identify these materials and to collect bulk
samples of all suspect ACM encountered. All samples will be submitted to an approved laboratory for
determination of the asbestos content.
Excavation activities will temporarily cease in areas that encounter possible ACM until sample results
determine if ACM is present or not present. Excavation work will be adjusted to work in other areas until
the assessment work is completed. When ACM is confirmed to be present, a Utah-certified asbestos
contractor will be contacted to submit an emergency notification to UDAQ for proper removal of the ACM.
The ACM will be properly containerized into poly bags and/or placed into 55-gallon, open-top drums for
transport and disposal at the Mountain View Landfill, located at 6976 West California Avenue in Salt Lake
City, Utah, or another facility permitted to receive ACM waste. After removal of the ACM waste, the
Engineer will perform a visual clearance inspection to verify that the ACM waste has been removed prior
to resuming soil removal operations at that location. All work will be completed in accordance with local,
state, and federal regulations.
7.2 OTHER SUSPECT WASTES
During excavation activities, excavated soil will be field screened for impacts to soil and or other suspect
waste not related to the petroleum impacts that may require special management and disposal. The field
screening may be performed by the Engineer and/or Contractor, who are both qualified environmental
professionals to screen for such conditions. Field screening will be by visual identification (e.g., different
colored materials), olfactory observations (smells), and/or use of a photoionization detector (PID) to
identify suspect VOC wastes, or other environmental impacts (e.g., excessive solid waste not suitable for
use as backfill). Once impacted soil or waste is observed, excavation activities will be terminated in that
location for sample collection and analysis to identify a suitable waste management strategy. Excavation
work will be adjusted to work in other areas until the assessment work is completed. Additional waste
streams discovered unrelated to the petroleum impacts will be coordinated with DERR through verbal and
written notification by CTP DEV or its representative to assure agency engagement in managing the
waste using best practices.
7.3 SAMPLE WASTE ANALYSES
All samples collected for waste characterization will be placed in laboratory-supplied containers, properly
labeled, placed on ice in laboratory-supplied coolers and transported under chain of custody protocol to a
Utah-certified laboratory (e.g., ChemTech Ford). Laboratory analysis for unknown contaminants shall
include Recourse Conservation and Recovery Act (RCRA) metals by EPA Method 6010, VOCs by EPA

19 February 14, 2025
Method 8260, polychlorinated biphenyls (PCBs) by EPA Method 8082, and semi-volatile organic
compounds (SVOCs) by EPA Method 8270.
7.4 ON-SITE MATERIALS MANAGEMENT
During excavation activities, if material is encountered that requires on-site storage pending laboratory
analysis, the material shall be managed as follows:
• Material shall be placed on-site in stockpiles not to exceed 100 cubic yards in an area that is
away from clean overburden stockpiles or soil impacted with diesel awaiting transportation.
• The material shall be stockpiled on areas covered with asphalt or 6-mil polyethylene sheeting
over soil. If material storage will be on the ground, soil samples will be collected from the soil
beneath the stockpile to confirm all suspected contaminants have been removed following
material stockpile removal.
• Containment berms around stockpiles shall be constructed to prevent runoff onto surrounding
soils and/or stormwater collection grates.
• Stockpiled material will be covered with 6-mil polyethylene sheeting or tarps as appropriate based
on the size and layout of the stockpiles.
7.5 MATERIALS TRANSPORTATION
All trucks transporting the materials will be covered/tarped prior to leaving the Site. The trucks will also be
cleaned of debris prior to exiting the Site to prevent track-out of potentially contaminated materials. All
trucks will have completed bills of lading and/or waste manifests prior to leaving the Site. Weigh tickets
and other documents (profiles/manifests) will be included in the Corrective Action Completion Report to
document proper management of the waste.

20 February 14, 2025
8.0 GROUNDWATER MONITORING PROGRAM
Closure of the two LUST releases will require achievement of the site-specific cleanup standards
described in Section 2.1 (i.e., ISLs or other applicable standards agreed by DERR). The soil and LNAPL
removal described in this CAP will eliminate the source of impacts observed as dissolved-phase TPH-
DRO concentrations in the groundwater, and the groundwater concentrations are expected to attenuate
over time. Monitoring of groundwater will be performed following the soil excavation and LNAPL removal,
including monitoring of ponded groundwater in the open excavations and groundwater at the periphery of
the site using existing groundwater monitoring wells. The program for assessing groundwater in the open-
water ponds and in monitoring wells is described in this section.
8.1 PONDED GROUNDWATER ASSESSMENT
The open excavations with ponded water will be sampled periodically, starting with bi-monthly
measurements for an initial 6-month period (i.e., three events); after which, the sampling frequency will be
adjusted based on the results of the first three sample events and the need for excavation backfilling
based on the land development schedule. Four samples will be collected per event from four differing
areas within the excavation limits.
Samples will be collected in laboratory-supplied containers and analyzed by a Utah Certified Laboratory
for BTEXN by EPA Method 8260 and TPH-DRO by EPA Method 8015. All field documentation,
equipment decontamination, and groundwater sampling shall follow the Tetra Tech Standard Operating
Procedures presented in Appendix F.
The ponds will remain open as long as Site development allows to facilitate natural aerobic
biodegradation of dissolved petroleum constituents. The Site will remain secured by the existing
perimeter fence to prevent potential human exposures, and if necessary, deterrents such as sound
devices or predator decoys will be placed around the ponds to deter birds from inhabiting them while they
are open.
8.2 SITE CLOSURE MONITORING
Post corrective action, groundwater monitoring will be performed quarterly for the first year following
corrective action and then semi-annually (if necessary) until it can be demonstrated that corrective action
objectives have been met and constituents of concern (e.g., TPH-DRO) are below the designated
cleanup standards described in Section 2.1. CTP DEV proposes groundwater monitoring of the following
existing wells, which will be protected during corrective action.
On-Site Wells
Monitor wells W-9, W-19, W-20, and W-21. See Figure 2 for well locations.
Off-Site Wells
Monitor wells W-22, W-23, W-24, W-25, and W-27A. See Figure 2 for well locations.
In the event, groundwater samples collected from the open water ponds described in Section 8.1 do not
meet the cleanup standards, and CTP DEV needs to close the excavations to support development, four
new wells will be installed within the excavation boundaries as replacement wells to allow continued
groundwater monitoring. The locations of the wells will be equal distance apart and within the interior of
the former diesel plume boundary and be based on the results of the open water sampling. The
placement of the wells will be coordinated with the DERR. The wells will be constructed with 2-inch PVC

21 February 14, 2025
according to Standard Operating Procedure (SOP) 21 Monitoring Well Construction, provided in
Appendix F.
The wells will be sampled according to SOP-08 or SOP-8A in Appendix F. Samples will be collected in
laboratory-supplied containers and analyzed by a Utah Certified Laboratory for BTEXN by EPA Method
8260 and TPH-DRO by EPA Method 8015.

22 February 14, 2025
9.0 COMPLETION REPORT
In accordance with UAC R315-101-6(d), CTP DEV will prepare and submit to DERR for review and
approval a Corrective Action Completion Report when corrective action activities are completed. The
report will document the following:
• Narrative of the work performed, including deviations from this CAP, if any, as approved
during the work by the DERR.
• As-built drawings to show the final limits of excavation.
• Total weight of soil disposed of at the ETT and/or the SLV Landfill (or other destinations if
required based on the materials encountered and managed through the waste management
plan).
• Table summarizing all soil loads removed from the Site. The table will include the date for
each load, the manifest number, and the weight on the disposal ticket. Copies of all the
manifests will be included as an appendix.
• Table summarizing the confirmation soil sample results compared to the ISLs and Tier 1
screening criteria.
• Scaled maps showing all environmental sample locations.
• Soil boring logs and/or well construction details.
• Copies of applicable sample collection data forms and laboratory analytical reports.
The Corrective Action Completion Report will provide a final summary of the corrective action process to
support LUST closures for Releases FFQ and OLX.

GENERAL NOTES:
1. ALL LINEWORK AND IMAGERY SHOWN HEREIN IS APPROXIMATE BUT CONSIDERED
SUFFICIENTLY ACCURATE FOR STATED DESIGN AND CONSTRUCTION PURPOSES.
2. SOURCE OF EXISTING CONDITIONS TOPOGRAPHY IS THE USGS 3DEP.
SUMMARY OF WORK:
1. THE WORK IS THE EXCAVATION OF DIESEL-IMPACTED SOILS AT THE FORMER ABF
FREIGHT TRUCKING FACILITY LOCATED AT 55 SOUTH REDWOOD ROAD, SALT LAKE
CITY, UTAH. THE OBJECTIVE OF THE WORK IS TO REMOVE IMPACTED SOILS WITHIN
THE FOOTPRINT OF THE DIESEL LIGHT NONAQUEOUS PHASE LIQUID (LNAPL) PLUME
TO THE EXTENT PRACTICAL. BURIED TANKS WILL BE UNCOVERED INSIDE AND ON
THE EAST SIDE OF THE FUELING BUILDING. THE CONTRACTOR SHALL BE
RESPONSIBLE FOR THEIR REMOVAL AND DISPOSAL.
2. THE WORK CONSISTS OF ALL LABOR, MATERIALS, AND EQUIPMENT NECESSARY TO
COMPLETE THE FOLLOWING ACTIVITIES IN THE GENERAL ORDER LISTED BELOW:
2.1. COMPLETE SITE PREPARATION ACTIVITIES.
2.2. REMOVE ASPHALT AND CONCRETE COVER.
2.3. EXCAVATE CLEAN OVERBURDEN SOIL, STAGE FOR USE AS BACKFILL, AND
REPLACE AS BACKFILL UPON COMPLETION OF REMEDIATION.
2.4. EXCAVATE AND DISPOSE OF DIESEL-IMPACTED SOILS.
2.5. PLACE AGGREGATE BACKFILL TO SERVE AS BERMS FOR VEHICLE AND
PERSONNEL ACCESS.
2.6. REMOVE DIESEL LNAPL FROM OPEN EXCAVATIONS BY ENGAGING SUMP AND
TRAP (NOW ENVIROCARE) TO PRESSURE SPRAY, GATHER AND REMOVE DIESEL
FROM SURFACE OF GROUNDWATER.
2.7. SUPPORT GROUNDWATER REMEDIATION, WHICH MAY CONSIST OF APPLYING
CHEMICAL TREATMENT OR AIR SPARGING EQUIPMENT TO OPEN WATER PONDS.
2.8. PERFORM SITE RESTORATION, EXCAVATION, BACKFILL, AND GENERAL SITE
CLEANUP.
3. THE CONTRACTOR IS RESPONSIBLE FOR DEVELOPING A STORM WATER POLLUTION
PREVENTION PLAN (SWPPP) AND ITS IMPLEMENTATION.
4. BEFORE EXCAVATION OF SOIL, ALL ASPHALT AND CONCRETE SHALL BE STRIPPED
FROM EACH EXCAVATION CUT AREA. IT IS INTENDED TO LEAVE ASPHALT CONCRETE
COVER IN AREAS NOT EXCAVATED TO AID IN TRUCK TRAVEL ACROSS THE SITE.
EXCAVATED ASPHALT OR CONCRETE SHALL BE STAGED IN AN AREA WHERE IT WILL
NOT IMPEDE TRAFFIC FOR FUTURE REMOVAL BY OTHERS FOR RECYCLE
PROCESSING.
5. OVERBURDEN MATERIAL IS EXPECTED TO BE HETEROGENEOUS AND MAY CONTAIN
HISTORIC LANDFILL WASTE, SOIL AND PEA GRAVEL BACKFILL. OVERBURDEN SOIL
NOT IMPACTED BY DIESEL SHALL BE STOCKPILED AS DIRECTED ON C-101.
6. TOTAL EXCAVATION DEPTH IS PLANNED AT 12 FEET BELOW EXISTING GRADES
(BGS).SHALLOWER OR DEEPER EXCAVATIONS ARE POSSIBLE BUT WILL DEPEND ON
ACTUAL SITE CONDITIONS AND DIRECTION BY ENGINEER. DEPTH TO WATER IS
ANTICIPATED TO BE 7 TO 10 FEET BGS. THERE IS NO DELIBERATE PLAN TO REMOVE
GROUNDWATER AS PART OF THE EXCAVATION WORK.

1'' = 50'
CORRECTIVE ACTION PLAN
SCALE: 1" = 50'
GENERAL NOTES:
1. ALL LINEWORK AND IMAGERY SHOWN HEREIN IS APPROXIMATE BUT CONSIDERED
SUFFICIENTLY ACCURATE FOR STATED DESIGN AND CONSTRUCTION PURPOSES.
2. SOURCE OF EXISTING CONDITIONS TOPOGRAPHY IS THE USGS 3DEP.
PROJECT BOUNDARIES:
1. SHEET C-101 SHOWS THE LIMITS OF THE PROJECT BOUNDARY. PROJECT BOUNDARIES
ARE PROPERTY LINES ON THE NORTH, WEST, AND SOUTH SIDES. TO THE EAST ROCKY
MOUNTAIN POWER (RMP) HAS ESTABLISHED AN ASPHALT BERM TRAVERSING THE
PROPERTY FROM NORTH TO SOUTH. THE BERM DEFINES THE WESTERN BOUNDARY
OF RMP'S LAYDOWN YARD AND EASTERN BOUNDARY OF THE PROJECT. NO TRUCK
TRAFFIC OR MATERIAL STORAGE WILL OCCUR WITHIN THE RMP LAYDOWN YARD.
NEW PROPERTY INGRESS AND EGRESS:
1. AS SHOWN ON DRAWING C-101, THE ENTRANCE TO THE SITE WILL NEED TO BE MOVED
EAST FROM THE EXISTING ENTRANCE WITHIN THE PROJECT BOUNDARIES.
CONTRACTOR WILL BE RESPONSIBLE FOR CONSTRUCTION AND SECURITY OF A NEW
ENTRANCE TO THE SITE. THE NEW GATE FOR THE NEW ENTRANCE SHALL BE
EQUIVALENT IN FUNCTION AND SECURITY TO THE EXISTING STRUCTURE. CONCRETE
CURBING ALONG SOUTH TEMPLE STREET WILL NEED TO BE CUT WHEN ENTRANCE IS
ESTABLISHED.
PETROLEUM RELEASE FFQ AND OLX:
1. THE PROJECT CONSISTS OF SOIL EXCAVATION FOR TWO DIFFERENT BUT
OVERLAPPING PETROLEUM RELEASES. ONE OF THE RELEASES (RELEASE OLX), THE
CORRECTIVE ACTION SHALL BE PAID BY THE STATE OF UTAH, DIVISION OF
ENVIRONMENTAL RESPONSE AND REMEDIATION (DERR) PETROLEUM STORAGE TANK
FUND (PSTF) IN ACCORDANCE WITH STATE REGULATIONS. THE OTHER RELEASE (FFQ)
IS NOT COVERED BY THE FUND AND WILL BE PAID BY THE PROPERTY OWNER. THE
APPROXIMATE BOUNDARIES OF THE TWO RELEASES ARE SHOWN ON DRAWING C-101,
RELEASE OLX IS HIGHLIGHTED IN LIGHT GREEN. THE ACTUAL BOUNDARY BETWEEN
RELEASES OLX AND FFQ MAY BE ADJUSTED DURING THE WORK BASED ON FIELD
OBSERVATIONS AND DISCUSSIONS WITH THE DERR.
2. THE CONTRACTOR WITH THE HELP OF TETRA TECH SHALL TREAT THE TWO RELEASE
EXCAVATIONS AS SEPARATE PROJECTS REQUIRING SEPARATE BILLING TO THE
CLIENT CTP DEV LLC. TETRA TECH PERSONNEL WILL FIELD MARK THE TWO DIFFERENT
EXCAVATIONS.
SOIL EXCAVATION:
1. EXCAVATE TO LINES, GRADES, AND WORKING ELEVATIONS SHOWN ON THE
DRAWINGS, OR AS DIRECTED BY THE ENGINEER, TO REMOVE CLEAN OVERBURDEN
SOIL AND DIESEL-IMPACTED SOIL.
2. SEGREGATE CLEAN OVERBURDEN SOIL FOR TEMPORARY STOCKPILING ON SITE AND
REUSE AS EXCAVATION BACKFILL UPON COMPLETION OF REMEDIATION.
3. SEGREGATE AND PLACE DIESEL-FUEL IMPACTED SOIL INTO TRUCKS FOR
TRANSPORTATION AND DISPOSAL AT AN APPROPRIATE LANDFILL FACILITY AS
DIRECTED BY THE ENGINEER BASED ON ANALYTICAL RESULTS (E.G., SALT LAKE
COUNTY LANDFILL FOR NONHAZARDOUS SOIL AND GRASSY MOUNTAIN LANDFILL FOR
HAZARDOUS SOIL). TEMPORARY STOCKPILES OF DIESEL-IMPACTED SOIL MAY BE
ESTABLISHED WITH APPROVAL BY THE ENGINEER AND PROVIDED NO RELEASES OF
SOIL OR PETROLEUM OCCUR FROM THE STAGING AREAS.
4. MONITOR WELLS TT-MW-1, TT-MW-2, TT-MW-3, W-21, W-9, MW-7, W-20, AND W-19 SHALL
REMAIN INTACT. ENGINEER SHALL BE NOTIFIED IN ADVANCE IF A WELLS CANNOT BE
SAVED.
5. FACILITATE ENGINEER'S ACCESS FOR POST-EXCAVATION VERIFICATION SAMPLING
AROUND THE PERIMETER OF THE EXCAVATION.
6. NOTIFY THE ENGINEER OF UNEXPECTED SUBSURFACE CONDITIONS.
7. CORRECT OVER-EXCAVATED AREAS WITH CLEAN ON-SITE FILL AT THE EXPENSE OF
THE CONTRACTOR AS DIRECTED BY THE ENGINEER.

1'' = 20'
EXCAVATION AND BACKFILL PLAN
SCALE: 1" = 20'
GENERAL NOTES:
1. ALL LINEWORK AND IMAGERY SHOWN HEREIN IS APPROXIMATE BUT CONSIDERED
SUFFICIENTLY ACCURATE FOR STATED DESIGN AND CONSTRUCTION PURPOSES.
2. SOURCE OF EXISTING CONDITIONS TOPOGRAPHY IS THE USGS 3DEP.
SOIL EXCAVATION:
1. EXCAVATE TO LINES, GRADES, AND WORKING ELEVATIONS SHOWN ON THE
DRAWINGS, OR AS DIRECTED BY THE ENGINEER, TO REMOVE DIESEL-IMPACTED
SOIL.
2. EXCAVATION STARTS AT CUT 1 AND PROGRESSES TO CUT 2, THEN CUT 3 AND
CONTINUES IN NUMERICAL SUCCESSION. DEVIATIONS FROM THIS PLAN NEED TO BE
DISCUSSED WITH THE ENGINEER BEFORE PROCEEDING.
3. TEMPORARY BERMS WILL NEED TO BE CONSTRUCTED AS WORK PROGRESSES AS
SHOWN ON THE PLAN AND DESCRIBED UNDER “AGGREGATE BACKFILL.” EACH CUT
SECTION SHALL BE COMPLETED BEFORE COMMENCING ADJACENT CUTS.
AGGREGATE BACKFILL:
1. SIDEWALLS OF EXCAVATED SECTIONS SHALL BE BACKFILLED WITH IMPORTED
AGGREGATE OR CRUSHED CONCRETE MATERIAL TO SHORE SIDEWALLS.
2. TEMPORARY BERMS SHALL BE ESTABLISHED WITH IMPORTED AGGREGATE
MATERIAL BETWEEN EXCAVATED CELLS TO PROVIDE VEHICLE AND FOOT ACCESS
BETWEEN EXCAVATED CELLS FOR DIESEL LNAPL REMOVAL AND SUBSEQUENT
GROUNDWATER TREATMENT AND EVALUATION.
3. EXCAVATION STABILIZATION AND TEMPORARY BERMS SHALL BE COMPLETED TO
ABOVE GROUNDWATER TO PROVIDE STABLE WORKING SURFACE AS SHOWN ON THE
DRAWINGS.
4. AGGREGATE BACKFILLS SHALL BE CONSTRUCTED USING WELL GRADED, ANGULAR
(NOT ROUNDED), AGGREGATE WITH 100% PASSING THE 2-INCH SIEVE, NO MORE
THAN 50% PASSING ½-INCH SIEVE, NO MORE THAN 10% PASSING NO. 4 SIEVE, AND
NO MORE THAN 2% FINES (PASSING THE NO. 200 SIEVE).
5. AGGREGATE MATERIAL FOR BACKFILLING OF SIDEWALLS AND TEMPORARY BERMS
SHALL BE APPROVED BY THE ENGINEER BEFORE DELIVERY TO THE SITE.
LNAPL REMOVAL:
1. DIESEL LNAPL WILL BE PERIODICALLY REMOVED BY SUMP AND TRAP LLC (STC) OF
SALT LAKE CITY. THE CONTRACTOR WILL HELP FACILITATE ACCESS TO INDIVIDUAL
CUT SECTIONS WHERE STC WILL PROVIDE A 5,000-GALLON OR SMALLER VACUUM
TANKER TRUCK TO REMOVE LNAPL. STC WILL USE A PRESSURE WASHER TO FORCE
LNAPL INTO CORNERS OF A CUT WHERE IT CAN USE A VACUUM TO RECOVER THE
DIESEL. PERIODIC VISITS BY STC WILL BE PERFORMED AND ACCESS BERMS MUST
BE CONSTRUCTED BETWEEN THE CUTS AS SHOWN ON SHEET C-102 AND
EXCAVATION CROSS-SECTIONS (SHEET C-103) TO PROVIDE INGRESS AND EGRESS
INTO THE EXCAVATIONS.
2. PAYMENT FOR STC SERVICES WILL BE PAID DIRECTLY BY THE OWNER AND IS NO
THE RESPONSIBILTY OF THE EARTHWORK CONTRACTOR.

GENERAL NOTES:
1. ALL LINEWORK AND IMAGERY SHOWN HEREIN IS APPROXIMATE BUT CONSIDERED
SUFFICIENTLY ACCURATE FOR STATED DESIGN AND CONSTRUCTION PURPOSES.
2. SOURCE OF EXISTING CONDITIONS TOPOGRAPHY IS THE USGS 3DEP.
BERM CONSTRUCTION:
1. THE BERMED CUT AREAS AIM TO CREATE MANAGEABLE AREAS WHERE DIESEL
LNAPL CAN BE RECOVERED EFFICIENTLY. THE GOAL IS TO HAVE A 30-FOOT BY
100-FOOT OPEN AREA SURROUNDED BY A BERM COMPOSED OF COARSE
AGGREGATE. SUMP AND TRAP WILL PERFORM THE DIESEL RECOVERY USING A
PRESSURE WASHER AND VACUUM TRUCK. IT IS THE INTENT OF THE BERMS THAT
THEY ARE CONSTRUCTED TO ALLOW TRUCK TRAFFIC EAST-WEST AND FOOT
TRAFFIC NORTH-SOUTH.
2. CROSS SECTION A (SHEET C-103) SHOWS THE FIRST EXCAVATION SECTION AS CUT 1
IN THE NORTHWEST CORNER OF THE PROPERTY. EXCAVATION SIDEWALLS SHALL BE
CUT AT 1 (HORIZONTAL) TO 2 (VERTICAL) SLOPES. ALL EXCAVATION CUTS SHALL BE
A MINIMUM OF 10 FEET FROM THE EXISTING FENCELINE OR PROPERTY LINE. ALL
PERIMETER EXCAVATION CUTS SHALL BE SHORED WITH COARSE AGGREGATE TO
STABILIZE THE SLOPES. NO CUT SHALL BE LEFT UNSHORED DURING THE
EXCAVATION WORK.
3. ALL BERMS SHALL BE CONSTRUCTED AT THE ANGLE OF REPOSE OF THE COARSE
AGGREGATE WHICH IS EXPECTED TO BE APPROXIMATELY 40 DEGREES (OR
SLIGHTLY LESS THAN 1H : 1V).
4. TOP OF THE BERM SHALL BE CONSTRUCTED FLAT TO FACILITATE FOOT AND
VEHICULAR TRAFFIC AND SHALL BE A MINIMUM OF 2 FEET ABOVE EXISTING
GROUNDWATER LEVELS BUT NOT MORE THAN 3 FEET.
5. SECTION A: THE TOP OF THE BERM ON CROSS SECTION A (SHEET C-101) IN THE
EAST-WEST DIRECTION SHOWS A BERM WIDTH 14.30 FEET. THIS IS TO FACILITATE
THE MOVEMENT OF A 5,000-GALLON VACUUM TANKER TRUCK EAST TO WEST AND
VICE VERSA, ALLOWING ACCESS TO INDIVIDUAL CUT SECTIONS FOR DIESEL LNAPL
REMOVAL.
6. SECTION B: THE TOP OF THE BERM ON CROSS SECTION B (SHEET C-101) SHOWS A
WIDTH OF 6 FEET. THE PURPOSE IS TO ALLOW FOOT TRAFFIC NORTH TO SOUTH.
7. SECTIONS C AND D: SHOW THE CROSS SECTIONS WEST-EAST AND NORTH-SOUTH
WITH EXCAVATION TERMINATIONS IN EACH DIRECTION.
8. SECTION E: THE TOP OF THE BERM IN THE WEST-EAST DIRECTION AND
NORTH-SOUTH DIRECTION SHALL BE 2 APPROXIMATELY 2 FEET ABOVE THE STATIC
GROUNDWATER ELEVATION EXPECTED TO BE APPROXIMATELY 8.5 BELOW GROUND
SURFACE (BGS). THE TOP OF THE BERM IN THE WEST TO EAST DIRECTION SHALL BE
RAMPED DOWNWARD/UPWARD TO MATCH EXISTING SITE GRADES AT SLOPES OF 15
PERCENT TO FACILITATE ACCESS BY THE VACUUM TRUCK OR OTHER EQUIPMENT.

NON-EXCAVATED SECTION1_SCALE: NTS
HISTORIC EXCAVATION SECTION2_SCALE: NTS
GENERAL NOTES:
1. DRAWING C-104 DETAILS SHOW EXPECTED NATIVE SOIL, FILL, AND POSSIBLY
SOLID/HAZARDOUS WASTE CONDITIONS WHERE EXCAVATIONS SHALL BE
PERFORMED. THE TWO SECTIONS PRESENT HANDLING PROCEDURES FOR TYPICAL
“NON-EXCAVATED” AND “HISTORIC EXCAVATION” AREAS.
2. NON-EXCAVATED AREAS MAY HAVE PETROLEUM IMPACTS NEAR THE GROUND
SURFACE WHERE DIESEL OR OTHER HYDROCARBONS HAVE BEEN RELEASED AT
THE GROUND SURFACE AND MIGRATED TO THE GROUNDWATER TABLE;
ALTERNATIVELY, THE SHALLOW SOIL MAY BE CLEAN WHERE NO SURFACE RELEASES
HAVE OCCURRED, AND IMPACTED SOILS MAY NOT BE ENCOUNTERED UNTIL THE
SMEAR ZONE AT THE WATER TABLE IS REACHED.
3. HISTORIC EXCAVATION AREAS ARE EXPECTED TO CONSISTS OF CLEAN BACKFILL
MATERIAL FROM THE GROUND SURFACE TO THE WATER TABLE. THESE AREAS
WERE PREVIOUSLY EXCAVATED TO REMOVE IMPACTED SOIL AND WERE BACKFILLED
GENERALLY WITH PEA GRAVEL THAT CAN BE PRESERVED FOR USE AS FUTURE
BACKFILL MATERIAL.
4. BECAUSE THE SITE WAS FORMERLY USED FOR SOLID WASTE LANDFILLING DURING
THE LATE 1800 AND EARLY 1900, A WASTE MANAGEMENT PLAN HAS BEEN
ESTABLISHED TO AID THE EVALUATION AND DISPOSAL DECISION MAKING PROCESS
DURING THE WORK. KEY ELEMENTS OF THE WASTE MANAGEMENT PLAN ARE
SUMMARIZED BELOW IN THE EVENT WASTES OTHER THAN PETROLEUM-IMPACTED
SOILS ARE ENCOUNTERED.
WASTE MANAGEMENT:
1. PAST USE OF THE SITE AS A HISTORICAL LANDFILL PRESENTS THE POSSIBILITY FOR
SOIL AND/OR WASTE TO CONTAIN CONTAMINANTS OTHER THAN PETROLEUM THAT
REQUIRE CHARACTERIZATION AND SPECIAL HANDLING PROCEDURES FOR PROPER
DISPOSAL. THIS WASTE MANAGEMENT PLAN (WMP) ESTABLISHES THE PROCEDURES
FOR CHARACTERIZATION, ON-SITE HANDLING AND STAGING, AND DISPOSAL TO
MITIGATE POSSIBLE ENVIRONMENTAL HAZARDS TO HUMAN HEALTH AND THE
ENVIRONMENT.
2. GIVEN THE HISTORIC USE OF THE AREA FOR SOLID WASTE DISPOSAL,
ASBESTOS-CONTAINING MATERIALS (ACM) OR TRANSITE® SIDING/PIPING MAY BE
ENCOUNTERED BGS AT THIS SITE. IF ENCOUNTERED, A UTAH-CERTIFIED ASBESTOS
INSPECTOR WILL BE AVAILABLE DURING EXCAVATION ACTIVITIES TO IDENTIFY
THESE MATERIALS AND TO COLLECT BULK SAMPLES OF ALL SUSPECT ACM
ENCOUNTERED. ALL SAMPLES WILL BE SUBMITTED TO AN APPROVED LABORATORY
FOR DETERMINATION OF THE ASBESTOS CONTENT.
3. EXCAVATION ACTIVITIES WILL CEASE IN ANY AREA THAT ENCOUNTERS POSSIBLE
ACM UNTIL SAMPLE RESULTS DETERMINE IF ACM IS PRESENT OR IS NOT. WHEN ACM
IS ENCOUNTERED, A UTAH-CERTIFIED ASBESTOS CONTRACTOR WILL BE
CONTACTED TO SUBMIT AN EMERGENCY NOTIFICATION TO DAQ FOR PROPER
REMOVAL OF THE ACM. THE ACM WILL BE PROPERLY CONTAINERIZED INTO POLY
BAGS AND/OR PLACED INTO 55-GALLON OPEN-TOP DRUMS FOR DISPOSAL. THESE
MATERIALS WILL THEN BE DISPOSED AT MOUNTAIN VIEW LANDFILL, LOCATED AT
6976 WEST CALIFORNIA AVENUE IN SALT LAKE CITY, UTAH, OR ANOTHER FACILITY
THAT IS PERMITTED TO RECEIVE ACM WASTE. AFTER THE REMOVAL OF THE ACM
WASTE, TETRA TECH WILL PERFORM A VISUAL CLEARANCE INSPECTION TO ENSURE
THAT ALL ACM WASTE HAS BEEN REMOVED PRIOR TO RESUMING SOIL REMOVAL
OPERATIONS. ALL WORK WILL BE COMPLETED IN ACCORDANCE WITH ALL LOCAL,
STATE, AND FEDERAL REGULATIONS.
4. DURING EXCAVATION ACTIVITIES, EXCAVATED SOIL WILL BE ALSO FIELD SCREENED
FOR IMPACTS TO SOIL AND OR OTHER SUSPECT WASTE NOT RELATED TO THE
DIESEL CONTAMINATION THAT MAY REQUIRE SPECIAL MANAGEMENT AND DISPOSAL.
FIELD SCREENING WILL BY VISUAL IDENTIFICATION AND USE OF A PHOTOIONIZATION
DETECTOR (PID) TO DETECT SUSPECT WASTES, VOLATILE ORGANIC COMPOUNDS
(VOCS), OR OTHER UNIDENTIFIABLE CONTAMINATES. ONCE IMPACTED SOIL OR
WASTES ARE OBSERVED, EXCAVATION ACTIVITIES WILL BE TERMINATED TO
PROPERLY SAMPLE THE SUSPECTED MATERIALS AND IDENTIFY WASTE
MANAGEMENT STRATEGIES. ADDITIONAL WASTE STEAMS DISCOVERED UNRELATED
TO THE DIESEL CONTAMINATION WILL REQUIRE DERR NOTIFICATION OF THE
INCIDENT AND REQUIRE COORDINATION WITH STATE REGULATORS FOR THE BEST
MANAGEMENT PRACTICES.
5. DURING EXCAVATION ACTIVITIES, IF MATERIAL IS ENCOUNTERED THAT REQUIRES
ON-SITE STORAGE PENDING LABORATORY ANALYSIS, THE MATERIAL SHALL BE
MANAGED AS FOLLOWS:
5.1. MATERIAL SHALL BE PLACED ON-SITE IN STOCKPILES NOT TO EXCEED 100
CUBIC YARDS IN AN AREA THAT IS AWAY FROM CLEAN OVERBURDEN
STOCKPILES OR SOIL IMPACTED WITH DIESEL AWAITING TRANSPORTATION.
5.2. THE MATERIAL SHALL BE STOCKPILED ON AREAS COVERED WITH ASPHALT OR
6-MIL POLYETHYLENE SHEETING. IF MATERIAL STORAGE WILL BE ON THE
GROUND; FOLLOWING MATERIAL STOCKPILE REMOVAL SOIL SAMPLES WILL BE
COLLECTED FROM THE SOIL BENEATH THE STOCKPILE TO CONFIRM ALL
SUSPECTED CONTAMINANTS HAVE BEEN REMOVED.
5.3. CONTAINMENT BERMS AROUND STOCKPILES SHALL BE CONSTRUCTED TO
PREVENT RUNOFF ONTO SURROUNDING SOILS AND/OR STORMWATER
COLLECTION GRATES.
5.4. STOCKPILED MATERIAL WILL BE COVERED WITH 6-MIL POLYETHYLENE
SHEETING OR TARPS AS APPROPRIATE.
6. DURING EXCAVATION ACTIVITIES, ALL TRUCKS TRANSPORTING THE MATERIALS WILL
BE COVERED/TARPED PRIOR TO LEAVING THE SITE. THE TRUCKS WILL ALSO BE
CLEANED OF DEBRIS PRIOR TO EXITING THE SITE, TO PREVENT TRACK-OUT OF
CONTAMINATED MATERIALS. ALL TRUCKS WILL HAVE A PROPER BILL OF LANDINGS
AND/OR WASTE MANIFESTS PRIOR TO LEAVING THE SITE. WEIGHT TICKETS AND
OTHER DOCUMENTS (PROFILES/MANIFESTS) WILL BE INCLUDED IN THE CORRECTIVE
ACTION COMPLETION REPORT TO ENSURE PROPER MANAGEMENT AND
DOCUMENTATION OF THE WASTE STREAMS.
CLOSEOUT PROCEDURES:
1. UPON SUBSTANTIAL COMPLETION, COMPLETE THE FOLLOWING ITEMS AS
APPLICABLE BEFORE REQUESTING CERTIFICATION OF SUBSTANTIAL COMPLETION:
1.1. CONDUCT INSPECTION TO ESTABLISH BASIS FOR REQUEST THAT WORK IS
SUBSTANTIALLY COMPLETE.
1.2. CREATE COMPREHENSIVE LIST (INITIAL PUNCH LIST) INDICATING ITEMS TO BE
COMPLETED OR CORRECTED, VALUE OF INCOMPLETE OR NONCONFORMING
WORK, REASON FOR BEING INCOMPLETE, AND DATE OF ANTICIPATED
COMPLETION FOR EACH ITEM. INCLUDE COPY OF LIST WITH REQUEST FOR
CERTIFICATE OF SUBSTANTIAL COMPLETION.
1.3. DISCONTINUE OR CHANGE OVER AND REMOVE TEMPORARY FACILITIES AND
SERVICES FROM SITE, ALONG WITH CONSTRUCTION TOOLS, MOCKUPS, AND
SIMILAR ELEMENTS.
1.4. PERFORM FINAL CLEANING AS DESCRIBED BELOW.

Re:Subsurface Investigation Requirements and Petroleum Storage Tank Fund Eligibility
ABF Freight Site, located at 55 South Redwood Road, Salt Lake City, Utah
Facility Identification No. 4001342, Release Site OLX
Dear Mr. Duke:
On October 8, 2024, the petroleum storage tank (PST) system at the above-referenced site was
closed by removal. Soil and groundwater samples collected from the PST excavation contained
petroleum contaminants at concentrations exceeding Utah PST Facility Cleanup Standards (Utah PST
Rule R311-211-6).
In accordance with Utah PST Rule R311-202 and R311-205-2, you are required to report,
control, abate, and characterize the release; define the extent and degree of petroleum contamination;
evaluate the risks to human health and the environment; and remediate (cleanup) the release, as
required by the Division of Environmental Response and Remediation (DERR). A Subsurface
Investigation Report (SIR) must be submitted to the DERR within 90 days of your receipt of this
letter. Requirements for an SIR are detailed in the Leaking Underground Storage Tank (LUST)
Subsurface Investigation Report Guide dated May 2014, which can be found on the DERR’s website.
In accordance with Utah PST Rule R311-207-2(2), a PST Fund Eligibility Application must
be submitted before the responsible party incurs costs for which they intend to seek reimbursement
from the PST Fund. A PST Fund Claims Packet is enclosed. Please submit your PST Fund Eligibility
Application within 90 days to ensure that the costs you incur will be eligible for reimbursement to
the greatest extent possible. Please note that the DERR may not authorize payments from the PST
Fund if the claim is not filed within the time periods specified in Utah Underground Storage Tank
(UST) Act Section 19-6-424(1) or if appropriate approvals for work are not timely obtained as
specified in Utah UST Act Section 19-6-420.
Facility ID# 4001342

Re: Corrective Action Plan Requirements
Former ABF Freight Systems, Inc., located at 55 South Redwood Road, Salt Lake City, Utah
Facility Identification No. 4001342, Release Site FFQ
Dear Mr. Duke:

The Division of Environmental Response and Remediation (DERR) received an Annual
Groundwater Monitoring Report 2023 for the above-referenced site on January 25, 2024. The
DERR has reviewed the report submitted and determined that the contamination at your Release
Site must be cleaned up.

As outlined in Utah Admin. Code R311-202, Sections 280.66 and 280.67, a Corrective
Action Plan (CAP) to clean up the contamination at your site, must be completed and submitted
within 90 days of receipt of this letter. Cleanup levels for your site will be established using the
criteria and standards required by Utah Admin. Code R311-211, and as described in the attached
guidelines. The DERR will review the CAP for approval based upon evaluating the cleanup plans
for the protection of human health and the environment, cost-effectiveness, and use of appropriate
cleanup technology.
Please note that this site has additional environmental concerns beyond the petroleum
contamination; this property is also known as the South Temple Landfill site (DERR/EPA ID-
UT0001767318). Appropriate care should be taken to ensure the CAP includes procedures to
manage any non-petroleum-related contamination or landfill material encountered in accordance
with all local, state, and federal regulations.

Facility ID# 4001342
Page 2
The enclosed CAP Guide will provide a format for submitting a CAP. Any abatement or
cleanup activities at your leaking underground storage tank site must be performed by a Utah
Certified PST Consultant as outlined by Utah Admin. Code R311-201-2(a).
Please contact your project manager within 30 days to arrange a meeting to discuss cleanup
alternatives and the CAP requirements. If you have any questions concerning this compliance
schedule or the cleanup process at this Release Site, please contact Liberty Coe, the DERR project
manager, at (801) 5364100.
Sincerely,

Brent H. Everett, Director

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, unless qualified or notated within
the report. 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
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL 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.
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.
T8 Sample(s) received past/too close to holding time expiration.

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, unless qualified or notated within
the report. 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
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL 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.
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.

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, unless qualified or notated within
the report. 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.

Groundwater Sampling
Objective:
This Standard Operating Procedure (SOP) provides an overview of groundwater
sampling procedures. Site-specific groundwater sampling requirements, if necessary,
will be described in work plans or field sampling plans. Texts are available with
extensive information on drilling and monitoring well installation. Several ASTM
standards and journal articles have been included for training and reference purposes.
Forms:
Sampling Forms
Site Access Agreements
Equipment:
Equipment required for groundwater sample collection includes the following:
1. Sufficient disposable 1.5-inch-diameter, 3-foot-long, high-density polyethylene
(HDPE) sampling bailers - one per well plus several extras.
2. Peristaltic pump and sufficient disposable Teflon (approximately 6 inches per
sample) and Tygon tubing (length measured from pump head to sampling depth).
Related equipment required for groundwater sample collection includes the following:
1. Latex and/or nitrile sampling gloves - sufficient quantity to provide a change for each
sample collection event.
2. Notebook and/or field note form to record boring information and observations -
including appropriate preprinted forms required, such as groundwater elevation form,
well completion forms, water sample document, chain-of-custody form, etc.
3. Laboratory containers, labels, security seals to prevent sample tampering, and
chain-of-custody forms for the appropriate type and number of samples.
4. Laboratory-cleaned cooler, packing padding (bubble wrap or foam), packing tape,
and ice.
5. Rope or string and a sharp knife or scissors.
6. Sample filtration kit with sufficient high-capacity filters for completing task
(recommend at least twice the number of samples to be collected).
7. DOT-approved sealed drums for storage of purged well water, or a suitable location
to disperse of liquid (i.e., on-site treatment system).
8. Personal protective equipment as described within the Site Health and Safety Plan.
9. Water level indicator to determine well volumes prior to purging.
10. Lug wrench kit and/or socket wrench kit and appropriate keys to access monitoring
wells.
Procedures:
Tetra Tech, Inc. SOP-08

Allow groundwater monitoring wells to stabilize for at least one week prior to initiating
groundwater sampling activities. Prior to collecting groundwater samples for chemical
analysis, survey all wells (top-of-casing and ground surface) for horizontal position and
vertical elevation. If presence of free-product is suspected, check each well using an
oil/water interface probe to screen for light non-aqueous phase liquids (LNAPL) or
dense non-aqueous phase liquids (DNAPL). The water elevation in each well should be
measured to the nearest 0.01 foot using the interface probe or an electronic water level
indicator. If separate-phase liquid is discovered in a well, and if designated in work
plans or field sampling plans, collect a sample using a bailer.
Collect groundwater samples using the following procedures.
1. Open the groundwater monitoring well and allowed to stabilize for at least 5 minutes
prior to sampling.
2. Measure the water level in the well using an electronic water level indicator, or an
oil/water interface probe. Note any occurrence of LNAPL or DNAPL and record on a
sample record sheet.
3. Based on the depth to water, determine the volume of water contained in the well
casing per the MPS Standard Procedure for Well Casing Volume Calculation.
Prepare sampling area near first well to be sampled (unless otherwise instructed,
start with those wells with the lowest historical or suspected concentrations, and
advance to the wells more likely to be contaminated (This reduces chances for
cross-contaminating). Set plastic sheeting or a garbage bag near the well to set
sample bottles on and to rest sampling equipment).
4. After donning new clean disposable latex or nitrile gloves, begin purging water from
the monitoring well using a dedicated HDPE disposable bailer and a new length of
clean rope or string or a peristaltic pump with new Teflon and Tygon tubing. To obtain
a sample representative of groundwater conditions, purge the groundwater
monitoring well of a minimum of 3 to 5 well casing volumes prior to collecting the
samples. Measure the volume of purged water using a graduated pail, or other
container of known volume. Purging and sampling should be conducted using slow
and steady motions to avoid excessive agitation, increased sample turbidity, and
sample volatilization. Transfer purged water from the pail into 55-gallon drums, a
large plastic bulk liquid storage tank, or other appropriate storage container for
storage until disposal is arranged.
5. If designated in work plans or field sampling plans, measure temperature,
conductivity, dissolved oxygen, and pH using calibrated field instruments at the
beginning and during well purging to confirm that the sample is representative of
groundwater. Obtain samples for analysis after these parameters indicate constant
conditions, or after purging five well casing volumes.
6. Samples should be collected using the same HDPE disposable bailer used for
purging or with a new HDPE disposable bailer if well was purged using a peristaltic
pump. Transfer groundwater samples from the bailer to their appropriate sample
bottle. Every effort should be made to minimize turbulent flow between the bailer
and the sample bottles. Place samples in the appropriate containers in decreasing
order of volatility (e.g., purgeables and aromatics first, then PNAs and phenols, then
cyanides, and lastly, nitrate, sulfate and metals). Samples for dissolved metals
Tetra Tech, Inc. SOP-08

analysis will be collected using a 0.45 µm filter to remove fine particulates. Filters
and flow-through tubing are disposable, and should not be reused between samples.
All non-disposable filtration equipment should be thoroughly decontaminated
between samples; for more details on field filtering, see MPS Standard Operating
Procedure “Field Sample Filtration.” If there is insufficient sample volume to provide
all sampling needs, retrieve additional bailer volumes until all samples are collected.
7. To the extent possible, labels for laboratory containers should be completed (using
permanent ink) in advance of sample collection. Place the appropriate label on the
laboratory containers prior to filling with the sample. Add the sample to the container
as described above, fill in the date, time of collection, and any other missing
information, tightly cap the container, and place the tamper protection seal over the
container cap.
8. Wrap all glass sealed containers in bubble wrap or foam; then place into large 1-2
gallon zip-lock bags, label the outside of the bag, and place into the coolers.
Periodically add crushed ice to the coolers to maintain all collected samples under
chilled conditions (frozen gel packs are an acceptable alternative). Ice should first
be placed into separate large zip-lock bags to further isolate melt water from the
samples. Ice should be distributed evenly through out the cooler
9. Completely fill out the sample Chain-of-Custody documentation, seal in a watertight
zip-lock bag, and attach to the underside of the cooler lid with packaging tape. Ship
coolers or arrange delivery to the laboratory as soon as possible and before the
sample holding time expires.
10. Dispose of all gloves, bailers, rope/string, tubing, etc., used to collect the sample
prior to accessing the next well.
Post-Operation:
Dispose of development and purge water generated during the monitoring installation
and sampling into Department of Transportation- (DOT) approved 55-gallon drums or
large plastic bulk liquid storage tanks, or other appropriate containers. Removal and
proper off-site disposal of the water will follow characterization analyses.
Make sure well caps are replaced tightly, locked, or otherwise secured.

STANDARD OPERATING PROCEDURE
FIELD MEASUREMENT OF GEOCHEMICAL PARAMETERS
USING A MULTI METER AND FLOW-THROUGH CELL
1. Remove the protective cover from the multi-meter head. Remove the rubber cover from the dissolved
oxygen (DO) sensor. Inspect the probes and sensors for damage, including cracks in the pH
electrode or bubbles in the DO membrane. Repair as necessary according to manufacturer's
instructions.
2. Rinse the probe with distilled water.
3. Connect the electronic unit to the probe and turn it on. Calibrate the device according to
manufacturer’s instructions.
4. Rinse the probe with distilled water to remove calibration solution.
5. Install the probe into the flow-through cell. Connect the hose from the outlet of the pump to the inlet
barb on the flow-through cell. Install a hose on the outlet barb of the flow-through cell and place the
other end of the hose into a bucket to capture the purge water.
6. Begin purging. After approximately five minutes, begin taking readings from the multi-meter. Record
the various parameters into appropriate cells on the field form.
7. Refer to the project QAPP or SAP for stabilization criteria. The sample can be collected when the
criteria have been met.
8. Disconnect the pump outlet hose from the flow through cell and collect the samples out of this hose.
Do not collect samples from the discharge hose of the flow through cell.

STANDARD OPERATING PROCEDURE

SAMPLE PACKAGING AND SHIPPING

All environmental samples collected should be packaged and shipped using the following procedures:

PACKAGING

1. Label all sample containers with indelible ink (on the side, not on the cap or lid). Place labeled sample
bottles in a high quality cooler containing an adequate amount of ice and/or frozen blue ice (appropriate
for the season), making sure the cooler drain plug is taped shut.

2. Place the samples in an upright position and wrap the samples with absorbent, cushioning material for
stability during transport. Samples should not be loose; the cooler should be able to withstand rough
handling during shipment without sample breakage.

3. Fill out the appropriate shipping forms, and place the paperwork in a ziploc bag and tape it to the inside
lid of the shipping container. Shipping forms usually include: 1) a chain-of-custody form, documenting
the samples included in the shipment; 2) an analysis request form, specifying the laboratory analyses
for each sample. If more than one cooler is used per chain of custody, put a photocopy in the other
coolers and mark them as a copy.

4. Close and seal the cooler using fiberglass strapping tape.

5. Secure the shipping label with address, phone number, and return address clearly visible.

SHIPPING HAZARDOUS MATERIALS/WASTE

Hazardous materials need to be shipped using procedures specified under Federal Law. Samples need to
be shipped in ziploc bags or paint cans filled with vermiculite, depending on the level of hazard. Special
package labeling may be needed. Consult the project manager for specific shipping procedures.

STANDARD OPERATING PROCEDURE
EQUIPMENT DECONTAMINATION
The purpose of this section is to describe general decontamination procedures for field equipment in contact
with mine/mill tailings, soil, or water. During field sampling activities, sampling equipment will become
contaminated after it is used. Sampling equipment must be decontaminated between sample collection
points if it is not disposable. Field personnel must wear disposable latex or vinyl gloves while
decontaminating equipment at the project site. Change gloves between every sample. Every precaution
must be taken by personnel to prevent contaminating themselves with the wash water and rinse water used
in the decontamination process.
Table A-1 lists equipment and liquids necessary to decontaminate field equipment.
The following should be done in order to complete thorough decontamination:
1. Set up the decontamination zone upwind from the sampling area to reduce the chances of windborne
contamination.
2. Visually inspect sampling equipment for contamination; use stiff brush to remove visible material.
3. The general decontamination sequence for field equipment includes: wash with Liquinox or an
equivalent degreasing detergent; deionized water rinse; 10% dilute nitric acid rinse; deionized water
rinse; rinse with sample water three times.
4. Rinse equipment with methanol in place of the nitric rinse if sampling for organic contamination. Follow
with a deionized water rinse.
5. Decontaminated equipment that is to be used for sampling organics should be wrapped in aluminum
foil if not used immediately.
6.Clean the outside of sample container after filling sample container.
Alternatively, field equipment can be decontaminated by steam cleaning, rinsing with 10% dilute nitric acid,
and rinsing with deionized water.
All disposable items (e.g., paper towels, latex gloves) should be deposited into a garbage bag and disposed
of in a proper manner. Contaminated wash water does not have to be collected, under most circumstances.
If vehicles used during sampling become contaminated, wash both inside and outside as necessary. Heavy
equipment will be decontaminated by brushing loose soil from the equipment then steam cleaned.

STANDARD OPERATING PROCEDURE

SAMPLE DOCUMENTATION

Sample documentation is an important step to ensure the laboratory, project manager, and field personnel
are informed on the status of field samples. Depending on the specifics required for each project, a number
of forms will need to be filled out. Most sample documentation forms are preprinted carbonless triplicates,
enabling copies to be filed or mailed from labs or offices. The forms will be completed by field personnel,
who have custody of the samples. The office copy will be kept in the project file and subsequent copies sent
to the laboratory, or other designated parties. The responsibility for the completion of these forms will be
with each field crew leader. It is important the field crew leader is certain field personnel are familiar with the
completion process for filling out forms, and the expected information is included.

Potential documents to be completed clearly in ink for each sample generated include:

 Field Form
 Chain-of-Custody
 Custody Seal

If working on Superfund activities, the following additional forms will also be prepared:

 EPA Sample Tags
 SAS Packing Lists
 Sample Identification Matrix Forms
 Organic Traffic Report (if applicable)
 Inorganic Traffic Report (if applicable)
Tetra Tech, Inc. SOP-13

STANDARD OPERATING PROCEDURE

QUALITY CONTROL (QC) SAMPLES

Quality Control (QC) samples are submitted along with natural samples to provide supporting laboratory
data to validate laboratory results. QC samples typically are submitted blind, and do not have any unique
identifying codes that would enable the lab or others to bias these samples in any way. Usually, the time or
sampling location is modified in a way which will separate blank and standard samples from the rest of the
sample train. QC samples are identified only on field forms and in field notebooks. The following codes are
typically used:

N - Natural Sample Soil, water, air, or other material from a field site

SP - Split Sample A portion of a natural sample collected for independent analysis;
used in calculating laboratory precision

D - Duplicate Sample Two samples taken from the same media under similar conditions;
also used to calculate laboratory precision

BB - Bottle Blank Deionized water collected in sample bottle; used to detect
contamination in sample containers

CCB - Cross Contamination Blank Deionized water run through decontaminated equipment and
analyzed for residual contamination

BFS - Blind Field Standard Certified chemical constituent(s) of known concentration; used to
determine laboratory accuracy

TB - Travel or Trip Blank Inert material (deionized water or diatomaceous earth) included in
sample cooler; sent by the lab, the sample is used to determine if
contamination by volatiles is present during collection or shipping

In general, selected QC samples will be inserted into the sample train within a group of 10 to 20 samples.
Unless otherwise specified, QC samples will be prepared in the field. Deionized water for bottle blanks and
cross-contamination blanks will be collected from carboys and cubitainers used in the field. An exception to
field preparation of QC samples is some blind field standards. Since the analytes in some blind field
standards are to be mixed according to specific manufacturer's instructions, field conditions may not provide
the needed laboratory atmosphere. This is especially true for volatile organic compounds, which need to be
prepared just before analyzing. Under these circumstances, such blind field standards will be shipped to the
laboratory for preparation, keeping the concentration or manufacturer's QC Lot Number as blind as possible.

The number and types of samples submitted for each group of natural samples will be determined by the
project manager and others, including state or Federal agencies, and will be defined in the project work plan.
Each field crew leader will be responsible for all QC samples prepared in the field.

Methods for computing data validation statements can be found in EPA documents or obtained from the
laboratory.

STANDARD OPERATING PROCEDURE
MONITORING WELL DEVELOPMENT
(Surge Block, Hand Bailing, Pumping)
1. Inspect all well development equipment for damage before mobilization. Repair as necessary.
2. Review a completion log for each well to be developed, if available, to obtain completion depth and
screened interval information.
3. Decontaminate the water level probe, surge blocks and non-disposable bailers byscrubbing with brush
and Liquinox solution, and rinsing with distilled water.
4. Measure and record the depth to water and total depth. A variation the total depth measured vs. the
depth on the completion log mayindicate that sediment is present in the bottom of the casing. Note that
completion logs often use ground surface as a reference point; this may vary from the top of casing
elevation by inches to feet depending on the surface completion.
5. Use a hand bailer to remove water and sediment from the well. The bailer should be lowered to the
bottom of the wellto remove the sediment thatsettles there. Containerize the water if required. Continue
until there is a marked decreased in the turbidity of the water.
6. Gently lower the surge block into the well to a depth of about two feet below the water level. Slowly
raise and lower the surge block several times within this upper interval. Note that aggressive surging
should be avoided because it has the potential to draw in large amounts of sediment that can sand lock
the surge block in the well casing.
7. Remove the surge block and repeat Step 5.
8. Repeat Step 6, focusing on the interval about two feet lower than before. Wells that produce water
slowly may need recovery time between purging and surging to allow the targeted screened interval to
be saturated. Continue to alternate between Steps 5 and 6 until the entire screened interval has been
surged. It may be possible to use a pump to purge the well between surging events after the sediment
load decreases (higher sediment loads maycause the pump or tubing to clog). The pump intake should
be placed near the bottom of the well to remove sediment that settles there. Repeat the surging and
purging procedure until the evacuated water is visibly clean and essentially sand-free.
9. If specified in the project work plan, collect water samples for field determinations of temperature,
specific conductivity, and pH during the purging cycles. Continue developing well until field parameters
stabilize to values specified in the work plan.
10. Document field observations and the volume of water removed in the daily notes. Measure and record
the water level and well depth at the conclusion of the development process.
11. Clean the surge block, non-disposable bailer, and water level probe between wells.

STANDARD OPERATING PROCEDURE
FIELD MEASUREMENT OF GROUND WATER LEVEL
1. Check well probe prior to leaving for field for defects by placing probe in water and testing buzzer
and light. Repair as necessary. Make certain the well probe, a tape measure calibrated to tenths of
feet and extra batteries are in the carrying case.
3. Measure all wells (monitoring and domestic) from the top of the well casing in the north quadrant or
from a designated measuring point, as appropriate. Measure and record distance from measuring
point to ground level. Make sure measuring point is labeled on well, so future measurements can
be made from the same location.
4. Obtain a depth to water from measuring point to the nearest hundredth of a foot. Record data on
appropriate field forms.
5. Decontaminate well probe between each measurement by rinsing with deionized water. Additional
decontamination, such as Liquinoxscrubbing, may be required for certain wells; consult the project
work plan.
6. Measurements should be taken from the cleanest wells first, followed by wells of increased impacts.

STANDARD OPERATING PROCEDURE
METHOD 5035 SOIL SAMPLE COLLECTION
This Standard Operating Procedure (SOP) describes the field equipment and sampling methods for
subsurface sampling of soil material using direct push drilling for soil core collection, and method 5035 for
sample collection. Methods explained in this SOP are general in nature and may be different from those
identified in a project specific Sampling and Analysis Plan (SAP) or work plan. The project specific SAP or work
plan should be referenced for additions or deletions to the methods noted below.
FIELD EQUIPMENT
•Small trowel
•5035 Sampling devices (Terra Core or similar)
•Sample collection containers/preservatives (from the laboratory)
•Cooler
•Ice bags
•Tape Measure
•Field forms and field book
SUBSURFACE SAMPLING
Subsurface soil collection will be completed using direct push drilling.
Direct Push Technology
1. Verify the driller has a sample tube, adequate number of plastic sleeve tube liners, and required drive
/ retrieval equipment.
2. Install sample tube sleeve liner into sample tube and advance to the desired depth by appropriate
drive mechanism. If desired depth is greater than sample tube length, retrieve sample tube, extract
tube sleeve liner with sample, install new sleeve liner and continue advancing the original bore hole.
3. Place retrieved sample tube liner on work table. Using tubing sleeve cutter, cut sleeve open to
access sample.
3. Record lithology as outlined in the Unified Soil Classification System (USCS; method ASTM D2488)
or the USDA - NRCS classification system and document percent recovery from cores retrieved from
sample tube.
4. Based upon the project SAP or work plan, collect soil for laboratory analyses. When sampling for
organics, the sample should not be mixed to avoid potential volatilization.
5. Obtain a new unused sampler and remove the end cap. Seat the plunger on the Terra Core per the
manufacturer’s directions (see attached).
6. Expose the soil to be sampled by scraping the surface with a clean spatula or spoon. Push the
device into the soil until the sample chamber is full and then extract the device.
7. Wipe any soil or debris from the outside of the sampler with a clean paper towel. Rotate the plunger
90 degrees to align with the slots in the body of the sampler.
8. Place the mouth of the sampler into a laboratory-supplied vial containing the appropriate solvent
preservative and extrude the sample into the vial by pushing the plunger down. Replace the cap on
the vial immediately and gently swirl (do not shake) the vial to saturate the entire sample.
9. Complete a sample label on the vial. (Note: labels should be affixed to the vials prior to
weighing/reweighing the vials. Labels affixed after filling and weighing of the vials may introduce a
sample weight error).
10. Place the vial with the preserved sample in a locking plastic bag and place in a cooler with ice.
11. Repeat Steps 5 through 10 to collect as many vials per sample as directed by the laboratory for VOC
analysis.
12. Collect a portion of the soil sample in the same manner as above and extrude the sample into an
unpreserved vial or container (e.g., 40mL or 60mL VOA vial) for laboratory determination of percent
moisture. This data is needed for the laboratory to determine VOC concentrations on a dry weight
basis.
13. Immediately place filled sample containers into a sample cooler chilled to 4°C and including trip
blank samples. Samples collected by Methods 5035 / 5035A should be segregated from samples
with gross contamination or free product and packed in separate coolers.
14. Pack sample into laboratory supplied container (glass jars or resealable polyethylene bags (Ziploc or
equivalent) eliminating void space as possible and seal the container.
15. Dispose of plastic sleeve liners appropriately and decontaminate sampling tube between each
interval sampled if required by the SAP or work plan. Decontaminate sampling equipment between
sampling locations.

Equipment General
Ionization device (PID or FID)
Device accessories (regulator, tubing, filters, etc.)
Appropriate calibration gas
Sample containers (Ziplock re-sealable plastic bags or glass jars and aluminum foil)
Indelible pen or permanent marker.
INSTRUMENT OPERATION
1.Before taking the instrument to the field check the following:
Test the condition of the battery and recharge if necessary.
Make sure you have appropriate calibration gas in accordance with manufacturer
recommendations and project work plan.
Check the integrity of the instrument and its accessories. Repair or replace broken parts and
clean the sampling tip. On the PID clean the inlet filter.
Make sure you have all the accessories you will need for sampling.
If you are using the FID, check the hydrogen pressure and refill from the supply bottle if below
1000 psi.
If you are using the PID, check the expiration date on the span gas cylinder (normally 100
ppm isobutylene)
2. Arrive on-site with decontaminated equipment in working order. During transport, keep the
instrument temperature stable and moderate.
3. Follow the manufacturer's instructions for starting up the instrument. Turn the instrument on and
let it run for a few minutes, allowing the electronics to stabilize.
4. For the flame ionization detector (FID), let the electronics warm up for about 5 minutes and the
pump to run for at least 3 minutes before attempting to light the flame. After lighting the flame,
test the instrument with a known hydrocarbon (i.e., permanent marker etc.) to make sure the
flame remains lit.
5. Calibrate meter before leaving for the field and each day in the field when headspace will be
measured. Record results of calibration in the field book for the project in which the instrument is

being used. Calibrate the instrument by setting the zero and span against the calibration gases
following manufacture instructions. To zero the instrument you may use clean air, if available, or
a cylinder of compressed zero gas.
6. Complete your organic vapor readings and record the results according to the measurement
method below.
7. Shut down the instrument according to the manufacturer's instructions. Decontaminate and
carefully pack the instrument before leaving the site.
FIELD MEASUREMENT OF VOLITILE ORGANIC COMPOUND HEADSPACE
1. Place sample material in a Ziplock bag and seal. Mix contents in bag to break up soil clumps and
homologize. Alternatively, place sample to be tested in clean canning type jar. Cover the sample
tightly using aluminum foil and the outer ring of the jar lid. Be sure to mark container with sample
location (boring/test pit # and depth).
2. Allow sample to come to room temperature (approximately 70 - 80° F) by placing in warm location
not in direct sunlight. This can be accomplished by placing the container under the heater vent of
the vehicle in winter or in a closed vehicle in summer.
3. Insert probe through foil or small opening in the Ziploc bag. Probe should be placed in container
such that soil particles are not ingested into analyzer. Record maximum reading.
NOTE: Consistency in results is enhanced by using approximately equal portions of material,
similar jar or bag sizes and similar test temperatures. Moisture content may also affect readings
using some instruments.
MAINTENANCE
1. Disassemble and store meters in their case.
2. Charge batteries after each use as described in user's manual.
3. Occasional routine maintenance may be necessary ie. cleaning or replacing filters following
manufacturer recommendations. Any maintenance you feel unqualified to perform should be
handled by an authorized service representative.

STANDARD OPERATING PROCEDURE
INVESTIGATION DERIVED WASTE MANAGEMENT
Many sampling activities at environmental sites will generate materials that need special handling or
consideration to protect human health, to follow regulations, and to keep from spreading impacts across a
project site. This SOP is not intended to ensure that Federal, State, or local regulations are met, nor is it
considered to be a replacement for training in regulatory matters. It only provides guidance on handling and
storing investigation derived waste at sites potentially impacted by petroleum, and only covers waste
generation from drilling and groundwater sampling. The safety of Tetra Tech and subcontracted personnel is
of prime importance on all projects. Work around drill rigs and attempting to move or handle drums are
situations that can easily result in injury. The activities described in this SOP should be conducted only if an
approved Health & Safety plan has been reviewed by field staff.
Soil
Exploratory drilling and monitoring well installation will produce drill cuttings that are potentially contaminated
and need to be handled appropriately. The type of drilling will determine how the cuttings are brought to the
surface, which will in turn determine how they are captured or controlled.
1. Air rotary drill rigs usually produce drill cuttings from a chute or tube that is attached to the top of
the drill head. Capturing these cuttings requires a person (typically the driller’s helper) to direct
the cuttings coming from the chute into a suitable container. Much of the time the container is a
55-gallon steel DOT-approved drum. Roll off dumpsters or dump trucks may be used on large
projects. The cuttings will be wet when drilling through saturated materials, so plastic sheeting
may be needed to line dumpsters, truck beds, or other containers that are not water tight. The
area around the collection point may also need to be lined with plastic to collect cuttings that are
blown out of or otherwise are not captured in the container.
2. Auger drilling brings cuttings to the surface on the flights of the augers where they collect at the
ground surface. These cuttings are usually removed from the boring area with a shovel. The
cuttings can be shoveled directly into 55-gallon drums. Split spoon sampling is often conducted
during auger drilling to provide soil samples for logging or laboratory analysis. The field geologist
is responsible for making sure that the unused material from the split spoon samples is property
contained. This may include dumping them directly into a 55-gallon drum where the cuttings are
being placed, or temporarily placing them in a bucket that will then be dumped into the drum.
3. Direct push drilling usually generates soil cores in four-foot long sections that are brought to the
surface in disposable plastic tubes. The soil in these cores is then used by the field geologist for
logging and/or preparing laboratory samples. The field geologist is responsible for making sure
that the unused material from the cores is property contained. This may include dumping them
directly into a 55-gallon drum, or temporarily placing them in a bucket that will then be dumped
into a drum. The field geologist’s work area can be underlain by plastic sheeting or a tarp to catch
soil. Alternatively, the work area can be swept to collect soil that is not otherwise captured.
Water
The process of developing and sampling monitoring wells will produce water that is potentially contaminated
and needs to be handled appropriately. Groundwater in environmental site investigations is typically removed
from wells by bailing or pumping.
1. Waterretrievedfrom wellcasingswithbailerscanbepouredfrom thebailerintoa5-gallonbucket.
A 55-gallon steel drum placed in an unobtrusive area will be used at most project sites as the
main collection point. The water that is collected in the bucket(s) is then carried to the drum and
poured into it. The layout and logistics of some project sites may allow a drum to be placed next
to the well location. The water from the bailer can be poured directly into the drum in these
instances.
SOP-48
Tetra Tech SOP-48 Updated May 2017 Page 2 of 2
2. Water retrieved from well casings with pumps can be placed into containers via the discharge
hose (either directly from the pump, or the outlet of a flow cell if geochemical parameters are
being monitored). A 5-gallon bucket is most often used as an interim container, while a 55-gallon
steel drum placed in an unobtrusive area will be used as the main collection point. The water that
is collected in the bucket(s) is then carried to the drum and poured into it. The layout and logistics
of some project sites may allow a drum to be placed next to the well location. The water from the
discharge hose can be routed directly into the drum in these instances.
Decontamination Fluids
Water (with soap) is used to clean various sampling equipment that is used during investigations at petroleum
release sites. Decontamination techniques may include immersion in water, or using spray bottles.
1. Five-gallon buckets are typically used to hold wash and rinse water when the immersion method
is used for decontaminating sampling equipment. These fluids need to be refreshed throughout
the day, and at the end of the day. The fluids will be placed into a 55-gallon drum. This water can
be combined with well development or purge water.
2. Applying wash and rinse water to sampling equipment with spray bottles generates a small
amount of water, typically less than one half gallon in a day. This water should also be collected
and containerized pending characterization. This can be accomplished by holding the field
equipment over a bucket or basin while the water is being sprayed onto it. The water in the
bucket or basin can then be poured into a 55-gallon drum. This water can be combined with
well development or purge water
3. Decontamination of large equipment, like drill rods or augers, can be accomplished by standing
them up in a drum, or laying them in a trough. The water is thus captured and can be stored in a
55-gallon drum pending characterization.
Labeling
The 55-gallon drums need to be securely closed, including a snugly fitting lid and ring. A label needs to be
placed on each drum indicating the material present (drill cuttings, purge water), the source (boring/well
numbers), date of generation, and project contact information.
Characterization
The material in the drums is normally sampled to determine the types and concentrations of contaminants
present. The specific chemicals that will be tested for will depend on the type of petroleum released at the
site. Testing for hazard characteristics such as ignitability and corrosivity, and the concentrations of the eight
RCRA metals may also need to be conducted. The type of testing to be conducted, as well as the number
and types of samples collected (grab/composite) should be considered before the field work begins.
Disposal
The ultimate disposal of the soil and water will vary based on client considerations, and the levels of
contaminants present. Disposal options may include transportation to a hazardous materials storage facility,
transportation to a treatment facility, or disposal on-site when contaminant levels meet certain minimum
requirements. The disposal options should be discussed with the client before the field work begins.

STANDARD OPERATING PROCEDURE

MONITORING WELL CONSTRUCTION

Many states require certification and licensing for monitoring well drillers. Be sure you know the State's
regulations before arriving on-site, especially if drilling outside your own State.

1. Safety equipment required on-site of the drill rig is mandatory. Personal protective equipment includes (at
a minimum): hard hat, ear plugs, safety glasses, steel toed boots, gloves, first aid kit, and site safety plan
- with routes to hospitals known by all personnel on-site.

2. Arrive on-site with properly sized drilling equipment and materials for site conditions. All drilling equipment
and materials should be properly decontaminated prior to its arrival on-site. Decontamination usually
includes steam - or hot water-cleaning methods.

3. Drilling muds or drilling solutions of any kind are not to be used during drilling activities in conjunction with
monitoring well construction. Acceptable drilling techniques include air-rotary, cable tool, hollow-stem
auger or sonic. If unconsolidated material is encountered, it may be necessary to drive steel casing during
drilling to maintain borehole integrity. It is suggested threaded steel casing be used in lieu of welding joints
together to minimize this source of potential well contamination. Hydraulic jacks or the drill rig can be used
to pull back the steel casing following emplacement of plastic casing.

4. A detailed lithologic log shall be completed during drilling activities. Water bearing characteristics of the
formations should also be noted on the log. In addition, details of monitoring well construction should also
be described on the well log including total depth, perforated interval, sizes and types of construction
materials, etc.

5. Seven (7) - to 10-inch outside diameter hollow-stem augers can used in drilling shallow exploration drill
holes in many situations. Care is taken to avoid contamination due to oil and grease from the drill rig and
split-spoon sampler. Appropriate decontamination is performed of the drill rig between drill holes. Soil and
sediment samples are collected using a standard 1.4-inch inside diameter split-spoon sampler and a 140
pound drive hammer. The number of blows necessary to obtain an 18-inch length of sample is recorded
on the exploration log. Appropriate decontamination of the split-spoon sampler is performed between
sample depth intervals.
6. Install factory-slotted well screen and blank section of well casing into the borehole, with the well screen
set at the desired depth interval, based on site conditions. The well screen and casing will be selected
based on the type of contamination present; typically polyvinyl chloride (PVC), stainless steel or
polytetrafluoroethylene (PTFE; for organics).
Either a single- or multi-completion monitoring well can be constructed in a single borehole where hollow-
stem auger drilling is not used.

7. Backfill the annular space below and above the perforated well screen and to at least 2-feet above the
well screen with chemically-inert silica sand. Place a bentonite plug above the sand to ground surface.
Where appropriate, begin pulling temporary steel casing out of borehole as the sand and bentonite are
placed. For some sites, states may require bentonite (granular or chips) be placed to 3 feet above the
level of silica sand followed by placement of a tremied bentonite slurry or grout to the surface. Monitoring
well development is presented in SOP-22.

8. Place a locking well protector over well casing(s) after the outer steel drill casing has been removed from
the borehole, if necessary. The locking well protector will either be a flush-mount well cover or steel riser
with locking well cap. If a flush-mount well cover is used, an inner locking well cap will be installed. Place
bentonite a plug below the bottom of well protector with a 1- to 2-inch layer of sand at the base and within

Revised March 2017 Page 1 of 1
Tetra Tech

the flush-mount protector to allow drainage. This will allow water to drain from the flush-mount well to limit
the surface casing from accumulating atmospheric water. Grout well protector in place.

9. Lock the well with high quality lock.

Leaking Underground Storage Tank Petroleum Cleanup Project
Former ABF Freight
55 South Redwood Road, Salt Lake City, Utah
Facility ID No. 4001342 and Release Site FFQ & OLX
A diesel release has occurred at the former ABF Freight terminal at 55 South Redwood
Road, Salt Lake City, Utah. Tetra Tech has prepared a Corrective Action Plan (CAP),
approved by the Division of Environmental Response and Remediation (DERR) for
remediation of diesel-impacted soils and diesel product recovery. The DERR will
oversee the remediation of the petroleum-contaminated soil and groundwater at the
above site.
Site Description and Background
Two petroleum releases have been reported at this site: Release FFQ reported in 1988,
and the recent petroleum Release OLX, reported on October 8, 2024. The
environmental impacts associated with these releases have required the development
of a CAP to remediate both releases concurrently and support the redevelopment of the
site as part of The Power District.
Proposed Remediation Method
Soil excavation and diesel product recovery are the selected remedies to effectively
address both petroleum releases FFQ and OLX. Work will involve excavating
approximately 38,300 cubic yards of soil for disposal of impacted soil at the Salt Lake
Valley Landfill. Exposed diesel product that accumulates in the excavation on the
groundwater table, will be removed and disposed of at an approved facility. Trucks and
trailers will also be hauling clean gravel to the site for partial backfilling of the
excavation. Future work following corrective action will be collecting groundwater
samples from the excavation and monitoring wells for evaluation and reporting to the
State of Utah.
Schedule
Excavation is planned to begin on _______ (date) and is expected to take
approximately 12 weeks. Groundwater sampling will occur bi-monthly to quarterly
following corrective action.
