Wheeler LUST Investigation Work Plan_March 2024 1
1. INTRODUCTION
On behalf of Wheeler Machinery Company (Wheeler), Geosyntec Consultants, Inc. (Geosyntec) has
prepared this Work Plan to summarize proposed investigation activities associated with a leaking
underground storage tank (LUST) case. Investigation activities will be performed at the former H&E
Equipment property located at 4899 West 2100 South, West Valley City, Utah (Site). The Site is
identified in Utah Department of Environmental Quality (UDEQ) Division of Environmental
Response and Remediation (DERR) records as Facility Identification No. 4001265, and the proposed
investigation activities are associated with Release Site NPJ.
1.1 Background
Release Site NPJ was issued following DERR review of the Underground Storage Tank Permanent
Closure Notice (Closure Notice) that was presented to DERR in October 2017. The Closure Notice
provided a summary of tank removal activities for four underground storage tanks (USTs) used to
store diesel fuel and associated soil and groundwater sampling results. Three soil samples and two
groundwater samples were collected from the excavation during UST removal activities on October
3, 2017. The soil samples and one of the groundwater samples had results that were less than the
DERR Initial Screening Levels (ISLs). One groundwater sample (identified as TH-3 in the Closure
Notice) that was collected from the southeast corner of the UST excavation had a total petroleum
hydrocarbons diesel range organics (TPH-DRO) analytical result (15.7 milligrams per liter [mg/L])
that exceeded the DERR ISL of 1 mg/L. The other analytes (benzene, toluene, ethylbenzene, xylenes,
naphthalene [BTEXN], and TPH gasoline range organics [TPH-GRO]) for the TH-3 groundwater
sample were less than their respective DERR ISLs. No ISL exceedances were identified in any of the
other closure samples.
This Work Plan is provided in response to letters dated November 22, 2022, and February 8, 2023,
from DERR to Wheeler requesting that further investigation be conducted at the Site and that
Wheeler Machinery submit a Work Plan and Budget (WP&B) to DERR.
1.2 Investigation Objectives
The objective of this WP&B is to outline the proposed activities and estimated costs for investigation
of potential soil and groundwater impacts associated with Release Site NPJ. The purpose of the
proposed investigation is to characterize shallow soil and groundwater conditions in the vicinity of
the former USTs. If the investigation results indicate that no further investigation or corrective action
is warranted, the investigation report will provide information that will support closure of Release
Site NPJ.

Wheeler LUST Investigation Work Plan_March 2024 2
2. INVESTIGATION ACTIVITIES
2.1 Health and Safety Plan
Geosyntec will prepare a Site-specific Health and Safety Plan (HASP) prior to implementation of the
field work associated with this Work Plan. Elements of the HASP will include safety personnel,
hazard analysis, emergency response procedures, decontamination, personal protective equipment
(PPE), and monitoring.
2.2 Utility Surveying and Clearance
Prior to subsurface investigation activities, each proposed boring location will be cleared to ensure
safe drilling occurs. An underground utilities service (e.g., Blue Stake of Utah 811) will be notified
to mark known underground utilities near the proposed locations. The boring locations also will be
reviewed with Site personnel to assess potential conflicts with underground utilities. As an additional
precaution, each borehole location will be cleared to a depth of 5 feet below ground surface (bgs)
using a hand auger or air knife. Based on the results of utility surveying, boring locations may be
modified from those depicted in this Work Plan.
2.3 Drilling and Soil Sampling
Direct push and hollow stem auger drilling activities will be performed at the locations depicted
in Figure 1. The proposed boring locations are based on the following rationale:
• MW-1 and MW-2 will be located hydraulically downgradient from the former USTs.
• MW-3 will be located near the southeast corner of the former UST excavation and proximal
to the location of groundwater sample TH-3 that was collected during the 2017 UST
closure sampling.
• MW-4 will be located near the southwest corner of the former UST excavation.
Soil borings will be advanced to collect soil samples and to install groundwater monitoring wells
for collection of groundwater samples. Each boring will be drilled to an estimated total depth of
15 feet bgs.
During drilling activities, soil cores will be collected at 5-foot intervals to observe and describe
soil types and to screen for volatile organic compounds (VOCs) using a photoionization detector
(PID). The soil core will be logged in accordance with the Unified Soil Classification System.
One soil sample per boring will be collected and placed in clean, laboratory-supplied containers
for laboratory analysis. Evidence of impacts (e.g., strong hydrocarbon odors and/or elevated PID
readings) and the estimated depth of the capillary fringe will be used as a guide for the collection
of soil samples. For example, a soil sample will be collected from the interval that has the highest
PID reading at each boring and/or where petroleum hydrocarbon odors or staining are observed.

Wheeler LUST Investigation Work Plan_March 2024 3
If evidence of impacts is not observed and PID readings are less than 10 parts per million at a soil
boring, the soil sample will be collected at the estimated depth of the capillary fringe.
2.4 Well Construction
After drilling to total depth, a 2-inch Schedule 40 polyvinyl chloride (PVC) monitoring well will
be set in the open boring. Wells will be constructed with approximately 10 feet of well screen,
which will be screened across the water table. At each well, a sand filter pack will be used to
backfill the annular space between the well casing and borehole from total depth to approximately
2 feet above the top of the well screen. Hydrated bentonite chips will be placed above the sand
filter pack to a depth of approximately 1 feet bgs. Wells will be completed at the surface with 8-
inch flush mount traffic-rated well vaults. The well surface completion will be set in a concrete
collar to match the existing grade.
2.5 Well Development
The purpose of monitoring well development is to remove fine-grained materials or drilling fluids
introduced into the borehole during drilling activities, enabling hydraulic connectivity between the
well and the surrounding formation. The wells will be developed using a combination of pumping
and surging. Water quality parameters (pH, temperature, specific conductance, dissolved oxygen,
and oxidation-reduction potential) will be periodically measured and recorded during well
development activities. Depth to water measurements will also be recorded periodically during
and after well development. Well development will be considered complete when purged
groundwater is visibly clear or more than 5 borehole volumes of groundwater have been purged
from each well (as calculated from the maximum standing water elevation measured in the well).
2.6 Well Surveying
Following well installation, the wells will be surveyed relative to a local datum to enable evaluation
of groundwater flow direction using groundwater level data. The well survey will be performed
by Geosyntec using laser level survey equipment. The monitoring wells will be surveyed at the
ground surface and top of casing for vertical control.
2.7 Groundwater Monitoring
Groundwater monitoring will be performed at least 72 hours after well development to allow the
wells to equilibrate. Groundwater levels will be measured to the nearest 0.01 foot using an oil-
water interface probe. Measurements of the depth to light non-aqueous phase liquid (LNAPL) (if
present), depth to water, and total well depth will be recorded for each well. Well gauging
measurements will be referenced to the surveyed mark on the top of each well casing.
One groundwater sample will be collected from each monitoring well using a peristaltic pump and
disposable tubing. The tubing intake will be placed at the approximate midpoint of the saturated
screen interval. Groundwater samples will be collected using low flow sampling procedures.
During well purging, water levels will be measured to record drawdown of the water column, and
the pumping rate will be adjusted to minimize drawdown (typically less than 0.33 feet). Well

Wheeler LUST Investigation Work Plan_March 2024 4
purging will generally be maintained at a constant rate between 100 and 500 milliliters per minute
(mL/min) at each well. Water quality parameters will be measured every 3 to 5 minutes with an
in-line water quality meter equipped with a flow-through cell. Well purging will be considered
complete when three consecutive readings meet the following criteria:
• Temperature: ± 1 degrees Celsius (°C)
• pH: ± 0.1 standard units
• Specific conductivity: ± 3%
• Dissolved oxygen: ± 10%
• Oxidation-reduction potential: ± 10%
After well purging, a groundwater sample will be collected by filling sample bottles (laboratory-
supplied, 40-mL containers with hydrochloric acid preservative) directly from the pump discharge
tubing at a sampling rate that does not exceed the purging rate.
If LNAPL is detected during well gauging at a thickness greater than or equal to 0.01 feet, a
groundwater sample will not be collected. Geosyntec assumes that groundwater monitoring
activities will be completed in one field day. Well gauging measurements and water quality data
will be recorded on field sampling logs.
2.8 Laboratory Analysis
The soil and groundwater samples will be submitted for analysis to Pace Analytical Laboratory’s
(Pace’s) Mt. Juliet, Tennessee laboratory, which is certified by the State of Utah Department of
Health and is a National Environmental Accreditation Program (NELAP) accredited laboratory. A
total of two field duplicates and two trip blanks will be collected: one of each during the soil
sampling event, and one of each during the groundwater monitoring event in accordance with
DERR requirements.
Soil and groundwater samples will be submitted to the laboratory for analysis of the following:
• Total Petroleum Hydrocarbons – Diesel Range Organics (TPH-DRO) by USEPA Method
8015
• BTEXN and methyl tertiary-butyl ether (MTBE) by USEPA Method 8260.
2.9 Sample Handling and Custody
2.9.1 Sample Containers and Labeling
Upon collection, all samples will be placed into laboratory-supplied sample containers. Clean,
disposable, nitrile gloves will be worn during sample handling to prevent cross-contamination
between samples. Sample labels supplied by the laboratory will be filled out and affixed to all
sample containers. Sample container labels will include the following information at a minimum:
• Unique sample identification number
• Sampling date and time of sample collection (24-hour format)

Wheeler LUST Investigation Work Plan_March 2024 5
• Sampler’s name or initials
2.9.2 Sample Packaging
After labeling, each sample will be placed in a cooler containing wet ice to reduce the sample
temperature to approximately 4 (±2) °C during storage and transport to the laboratory. The samples
will be packaged and shipped in general accordance with laboratory specified procedures.
2.9.3 Chain of Custody
A Chain of Custody (CoC) form will be completed to track sample control and possession from
the time of collection through laboratory analysis. While the samples are in the custody of the field
staff, they will not be left unattended at locations where the samples may be tampered with. A
sample is considered to be in custody if the following conditions have been observed:
• It is in possession or view of the person in custody.
• It is locked in a secure area.
• It is placed in an area restricted to authorized personnel or it is placed in a container and
secured with a custody seal.
The analyses to be performed will be designated on the CoC form, including the quantity and types
of containers that comprise each sample and other pertinent sample information. One CoC form
will accompany each sample shipment. The duplicate copy of the CoC record will be retained by
the sampler.
2.10 Decontamination
Non-dedicated soil and groundwater sampling equipment (e.g., direct-push rods and tips, hand
augers, etc.) will be decontaminated between borehole locations by first washing in a solution of
Alconox and potable water, then rinsing with potable water, and finally rinsing with distilled water
and air drying. The oil-water interface probe used during groundwater monitoring will be
decontaminated prior to use at each well by washing with an Alconox detergent and rinsing with
distilled water. Decontamination activities will be conducted in a manner to contain and capture
liquids and other waste materials. Waste associated with decontamination activities will be
managed in accordance with procedures described in Section 2.11.
2.11 Investigation Derived Waste
Investigation derived waste (IDW) will consist of consumable field supplies (paper towels,
miscellaneous paper products, etc.), disposable PPE items (nitrile gloves), purge water,
decontamination water, and drilling cuttings. Consumable field supplies and PPE will be collected
and disposed of as non-hazardous solid waste. IDW will be segregated (solids and liquids),
containerized in 55-gallon drums, labeled, and temporarily staged at the facility’s waste storage
area pending offsite disposal based on the analytical results. Off-site transport and appropriate
treatment or disposal of IDW will be arranged by Geosyntec and performed with appropriate waste
management documentation.

Wheeler LUST Investigation Work Plan_March 2024 6
3. REPORTING
Upon completion of the sampling activities, a summary report will be prepared to document the
field activities completed under this Work Plan and present the investigation findings. The report
will include sample location figures, data summary tables, laboratory analytical reports, boring
logs with PID readings, well completion and well development logs, and associated supporting
materials. It will also include recommendations for the path forward for Release Site NPJ.

Wheeler LUST Investigation Work Plan_March 2024 7
4. COST ESTIMATE
This WP&B is based on 2023 Petroleum Storage Tank (PST) Fund cost guidelines. The estimated
costs for reimbursement from the PST Fund are $21,057.60, as detailed in Table 1. Bid solicitation
was performed in accordance with the Utah PST guidelines for consultant services exceeding
$5,000.
The scope of the proposed work and estimated costs are based on the following assumptions:
• Four monitoring wells will be installed at the proposed locations in accordance with the
methods described herein.
• Geosyntec will provide oversight of a survey of subsurface utilities to be performed by
Ground Penetrating Radar Systems (or a similar qualified subcontractor).
• Pacific West was selected to perform drilling and monitoring well installation, as they were
the lowest cost qualified bidder. Appendix A provides a summary of bids received from
qualified drilling contractors. The initial bid scope included the installation of three
monitoring wells and was changed to four monitoring wells after communication with the
DERR. Direct Push Services has not yet responded with a revised bid including four
monitoring wells. Regardless, Pacific West maintains the lowest bid and is, therefore,
selected.
• Geosyntec will provide field representatives to oversee and conduct field activities,
including drilling, monitoring well construction and development, soil and groundwater
sampling, and waste management. Estimated costs for Geosyntec oversight are based on
one day to complete drilling, soil sampling, and well construction activities, one day for
well development, and one day for groundwater sampling.
• During drilling activities, 4 soil samples will be collected for laboratory analysis.
• A groundwater sampling event will be performed in accordance with methods described
herein. One groundwater sample will be collected from each well (MW-1, MW-2, MW-3,
and MW-4) for laboratory analysis.
• Soil and groundwater samples will be analyzed by Pace National (or a similar qualified
laboratory) for total petroleum hydrocarbons (TPH); benzene, toluene, ethylbenzene, and
xylenes (BTEX); and methyl tertiary-butyl ether (MtBE).
• All laboratory analyses will be performed under standard turnaround times.
• Costs for profiling, transportation, and disposal of investigation-derived waste (soil
cuttings, purge water, and decontamination water) generated during drilling and sampling
activities are based on anticipated volumes and assumed non-hazardous waste
classification.

Wheeler LUST Investigation Work Plan_March 2024 8
Should the scope deviate from the assumptions listed above, Geosyntec and Wheeler will advise
DERR of the scope changes and associated cost increases for PST Fund reimbursement.

Mark Anderson
Pacific West Environmental & Infrastructure
3131 E. Hwy 199,
Springtown, TX 76082
Subject: Request for Bid – Wheeler Machinery Drilling and Monitoring Well
Installation
Dear Prospective Bidder:
On behalf of Campbell Companies, Geosyntec Consultants, Inc. (Geosyntec) is
requesting a proposal for drilling and monitoring well (MW) installation activities at
Wheeler Machinery (Wheeler) located at 4901 2100 S, West Valley, Utah. Details
regarding the project background and scope of work are outlined below.
SCOPE OF WORK
The proposed scope of work involves the installation of four monitoring wells and
four soil samples. The proposed locations for the MWs are labeled as MW-1 through
MW-4 in Figure 1.
Health and Safety
During field activities, crews will be required to attend and participate in a daily tailgate
safety meeting prior to commencing work each day. Appropriate personal protective
equipment (PPE) will be worn at all times during field activities. The drilling contractor
will be responsible to identify and provide PPE for its employees, and appropriate PPE
may include hard hat, high-visibility safety vest, steel toed boots, hearing protection, and
appropriate gloves. The drilling contractor will also provide traffic controls (traffic cones,
etc.) during field activities.
Mobilization
Geosyntec will provide oversight during field activities and will coordinate mobilization
dates and times with the drilling contractor. The drilling contractor will mobilize and
demobilize a drilling rig, field crew, support vehicles, and all required equipment and
materials to complete the scope of work.

SLC1090/Wheeler Drilling Bid Request
Subsurface Clearance
The drilling contractor will need to comply with subsurface clearance procedures and
requirements. Geosyntec will procure a third-party utility locating survey to identify
subsurface utilities in the drilling location areas. Public utility notification (Blue Stake of
Utah 811) will be conducted by Geosyntec and the drilling contractor, as appropriate.
After saw cutting/coring asphalt, the drilling contractor will clear a borehole using hand
auger, air knife or hydrovacuum excavation methods to a depth of at least 5 feet below
ground surface (bgs) at each drilling location.
Drilling
The drilling contractor will be responsible for drilling operations. Direct Push drilling
methods will be used to advance three borings: each will be cleared to 5 ft below ground
surface (bgs) using a hand auger or air knife, then drilled to a total depth of 15 feet below
ground surface. Drilling tools should be selected to provide the necessary diameter for
drilling tools and MW installation.
Continuous soil cores will be collected from one boring at 5-foot intervals to a total depth
of 15 feet below ground surface during drilling activities. The drilling contractor will
provide soil cores to Geosyntec field personnel for description of soil types and screening
for organic vapors using a photoionization detector (PID). Soil lithology is assumed to be
relatively uniform and will therefore only be classified at one of the borings. One soil
sample will be collected from each boring.
Well Construction
After drilling to total depth, a 2-inch Schedule 40 polyvinyl chloride (PVC) monitoring
well will be set in the open boring. Wells construction will include approximately 10 feet
of well screen with .010-inch slotted casing from 5-15 feet below ground surface, 10/20
silica sand from 4-15 ft bgs, hydrated bentonite chips from 2-4 ft bgs, and concrete from
0-2 ft bgs. Wells will be completed at the surface with 8-inch flush mount traffic-rated
well vaults. Each well will be developed by surging and pumping.
Decontamination and Investigation-Derived Waste Management
Drilling equipment will be pressure washed prior to each boring to minimize the potential
for downhole cross contamination. The drilling contractor will be responsible to provide
a temporary decontamination pad or a decontamination trailer for drilling equipment
decontamination activities.
SLC1090/Wheeler Drilling Bid Request
The drilling contractor will be responsible for transferring investigation-derived waste
(IDW) into 55-gallon drums for soil cuttings, decontamination water, and purge water.
Geosyntec will arrange for provision of drums through a third-party waste management
contractor, which will provide off-site transport/disposal of IDW.
Utilities and Site Cleanup
Water and electricity will be available at the Site, and the drilling contractor will need to
coordinate with Wheeler and Geosyntec to access these utilities. The drilling contractor
will need hoses and electrical cords to connect to these utilities.
The Site is paved, and the drilling contractor will take reasonable precautions to prevent
build-up of soil on the pavement during drilling and well construction activities, including
the use of plastic sheeting at the borehole and/or washing down the pavement following
drilling activities.
REQUIREMENTS FOR BID RESPONSE
Bid responses will address the requirements outlined in the proposed scope of work,
including any modifications, additions, or exceptions.
Geosyntec will subcontract directly with the successful bidder, and the drilling contractor
will need to meet the requirements of Geosyntec’s Supplier Portal.
Bids will be signed, dated, and submitted by e-mail to me at
[e-mail], no later than close of business on March 13, 2024. Please
contact me if you need additional time to respond to this bid request. Prospective bidders
will be notified of the project award.
Please contact me at [phone] if you have any questions regarding the information
provided in this bid request.

3.75-inch outside diameter (OD) direct push probe rods and 3.75-inch OD expendable
points to allow for adequate annular space to construct 2.0-inch diameter MWs.
 Each MW to be constructed using 10-foot lengths of 2.0-inch sch40 0.010-inch slotted
PVC well screen and 5-foot lengths of 2.0-inch sch40 PVC riser casing to ground surface.
A 10-20 sand filter pack to be emplaced within the annular space of each borehole from 4-
15 ft bgs with a hydrated bentonite chip seal from 2-4 ft bgs and concrete from 0-2 ft bgs.
 RMEC will also provide a locking j-plug and well pad finish consisting of an 8-inch
diameter traffic rated flush mount well vault cover with a cement pad. The pad is to be
constructed at an angle to provide surface water drainage away from the cover.
 Following completion of each MW, RMEC to perform development at each well by the
surging and pumping method using a peristaltic pump and new ¼-inch polyethylene and
tygon tubing at each well location. Up to 25 gallons per well to be removed or until the
well runs dry.
 RMEC to decontaminate tooling and equipment prior to mobilization and between each
boring, as necessary using either a hand brush or pressure washer with an Alconox
detergent. RMEC to provide a temporary decontamination pad for decontamination
activities and ensure the prevention of build-up of soil on the pavement during drilling and
well construction activities by use of plastic sheeting at each borehole and/or washing down
the pavement following drilling activities.
 RMEC to provide four (4) 55-gallon Investigative Derived Waste (IDW) drums for soil
and groundwater (up to 3 IDW drums for development/purge and decontamination water
and 1 IDW for soils). RMEC will be responsible for transferring IDW for soils,
decontamination water, and purge water into appropriate drums. RMEC understands the
IDW drums are to be temporarily stored onsite and off-site transport/disposal of IDW will
be coordinated by Geosyntec.
 Prior to MW installation, RMEC will coordinate with Utah Division of Water Rights
(UDWR) to obtain necessary authorization, Start Cards and well permits for the non-
production MWs up to two (2) weeks prior to drilling activities. Following successful
installation of the MWs and completion of fieldwork, RMEC will submit a Well Drillers
report for each MW.
 All necessary permits (Right-of-Way, Utah 811 Bluestakes and/or Ground Penetrating
Radar (GPR)) permits to be completed by the client prior to any subsurface activities to be
performed at the site.
