SUBJECT: Groundwater Monitoring Work Plan and Price
Work Assignment FQU-13-KLE
Former Jack’s Auto
606 West Center Street
Midvale, Utah

Dear Ms. Holyoak:

Kleinfelder is pleased to submit this Work Plan and Price for environmental services at the former Jack’s
Auto facility located at 606 West Center Street in Midvale, Utah (Site). Kleinfelder received work
assignment FQU-13-KLE from the Utah Department of Environmental Quality (UDEQ) Division of
Environmental Response and Remediation (DERR) on March 6, 2023, which requested that Kleinfelder
prepare a Work Plan and Price to conduct groundwater monitoring, arrange access agreements for sub
slab vapor sampling, and conduct free product recovery testing and monitoring at the Site.

BACKGROUND AND SITE DESCRIPTION

The Site owners formerly operated four underground storage tanks (USTs). In 1991, the four USTs were
removed from the Site. In 1989 and 1990, UST removal subsurface investigation work was conducted at
the west adjacent former Handimart property. Petroleum releases affecting soil and groundwater at the
two properties were reported to the UDEQ in 1991 and 1992. Sometime after 1991, a soil vapor
extraction (SVE) system was installed at the former Handimart property.

From 1993 through the present-day, additional groundwater monitoring wells, piezometers, and soil
borings were advanced at the Site and nearby properties to assess the two releases. Light non-aqueous
phase liquid (LNAPL), up to 6.6 feet thick, was observed in several groundwater monitoring wells and
piezometers. In 1995, a LNAPL recovery system was installed at the Site. The LNAPL recovery system was
only operated for approximately one month due to limited LNAPL recharge and recovery. Following
shutdown of the LNAPL recovery system, bailing was the primary method used for LNAPL recovery.

In general, groundwater across the Site ranges from approximately 30 to 48 feet below ground surface
(bgs). The groundwater flow direction is generally towards the west-northwest. Soils at the Site
generally consist of silty clay underlain by alternating layers of silt, sand, and gravel to the maximum
depth explored (approximately 50 feet bgs).

KLEINFELDER 849 West Levoy Drive, Suite 200 Salt Lake City, UT 84123-2964 p | 801.261.3336
SCOPE OF SERVICES

Our scope of services is based on our conversations with you regarding the groundwater monitoring
conducted in December 2022 and the tasks described in Work Assignment FQU-13-KLE. Our proposed
scope of services also includes groundwater monitoring well vault and casing repairs in accordance with
a telephone conversation with you on March 7, 2023.

Task 1 – Groundwater Monitoring and Well Vault Repairs

Prior to conducting work at the Site, Kleinfelder will update the Health and Safety Plan (HASP) for the
project. The HASP will include project and emergency contact information, descriptions of project
hazards, required personal protective equipment, and maps to a clinic and hospital.

15 groundwater monitoring wells are proposed for monitoring. Six of those 15 groundwater monitoring
wells were dry in December 2022 and are not proposed for sampling during this event. If enough
groundwater is measured in one or more of the six previously dry wells, Kleinfelder will contact you to
secure additional funds for sample collection and laboratory analysis. A list of wells proposed for
monitoring is shown in Table 1.

Upon mobilization to the Site, Kleinfelder will locate and open each of the 15 groundwater monitoring
wells proposed for monitoring. Prior to sample collection, the total depth and depth to fluid
measurements will be collected from each of the 15 selected groundwater monitoring wells using an
oil/water interface probe. Following gauging, one groundwater sample will be collected from each of the
nine groundwater monitoring wells proposed for sampling in Table 1. Prior to sample collection, each well
will be purged of three casing volumes of groundwater using a new, factory-sealed, weighted, disposable
bailer and allowed to recover to at least 80 percent of the static water level. Samples will not be
collected from wells with measurable LNAPL. Groundwater purged from wells during sampling activities

KLEINFELDER 849 West Levoy Drive, Suite 200 Salt Lake City, UT 84123-2964 p | 801.261.3336
will be spread across the paved ground surface and allowed to evaporate if measurable LNAPL is not
observed. One grab LNAPL sample will be collected from MW-17 using a disposable bailer. The LNAPL
sample will be handled, stored, and transported separately from the groundwater samples to reduce the
risk of cross contamination.

The samples will be decanted into appropriate containers, labeled, stored on ice, and transported under
chain-of-custody documentation to Pace National Center for Testing and Innovation (Pace) in Mt Juliet,
Tennessee (a Utah certified analytical laboratory) for analysis. The groundwater samples (including
one blind duplicate) will be analyzed for methyl tertiary-butyl ether (MTBE), benzene, toluene,
ethylbenzene, total xylenes, and naphthalene (MBTEXN) and total petroleum hydrocarbons (TPH) as
gasoline range organics (GRO) by EPA Method 8260 and TPH as diesel range organics (DRO) by EPA
Method 8015. The LNAPL sample will be submitted for laboratory analysis of flashpoint and density for
waste characterization purposes. Additionally, one trip blank will accompany the groundwater samples
to the laboratory and will be submitted for analysis of volatile organic compounds by EPA Method 8260.

Kleinfelder will also conduct in-field repairs and rehabilitation of the well vaults and accessible casing. To
the extent practicable, Kleinfelder will clean debris from the vaults, replace broken or missing well vault
bolts, and replace missing or non-functional well plugs. Where necessary and possible, rust will be
removed from the vault lids and locking flanges. Kleinfelder assumes that up to 20 well vaults will need
repairs or rehabilitation.

Task 2 – Access Agreements

Kleinfelder proposes to collect sub-slab vapor samples from three residential properties located above
or near the LNAPL plume. The sub-slab sample collection will take place in the future under a separate
work assignment. Figure 1 (included as Attachment A) shows the LNAPL plume as observed in December
2022. Based on our interpretation of the lateral extent of the LNAPL plume at the Site, we recommend
collection of sub-slab vapor samples from three residential structures located at the following
addresses:

• 7673 Allen Street,
• 7692 Allen Street, and
• 640 West Center Street.

Kleinfelder will work to obtain access agreements with the property owners of the three above-listed
residential properties. Based on our experience with businesses and residents in the Site vicinity, we
anticipate the need for English to Spanish translation services. A Kleinfelder employee will work with the
three property owners to explain the scope of work and terms of the agreements. Kleinfelder will use
the DERR’s standard access agreement form. If it becomes necessary to translate the access agreements
into Spanish (or any other language), Kleinfelder will need the UDEQ to provide Kleinfelder the
translated document. Kleinfelder assumes that UDEQ personnel will be available to meet with private
property owners if they are unwilling to meet with Kleinfelder or sign the access agreements.

Task 3 – LNAPL Gauging and Recovery Testing

Following receipt of the LNAPL sample analysis, Kleinfelder will mobilize to the Site to conduct an LNAPL
bail down test. First, Kleinfelder will open each of the ten groundwater monitoring wells listed in Table 2
and measure the depths to LNAPL and groundwater.

Table 2: LNAPL Gauging and Recovery Summary
Well ID Well Casing
Size (inches)
Estimated LNAPL Volume
(gallons)
MW-5 4 0.18
MW-8 4 1.57
MW-12 4 3.70
MW-17 4 3.10
MW-20 4 0.28
MW-21 4 0.05
MW-23 2 0.01
MW-24 2 0.07
MW-26 2 0.08
B-4 4 2.83

Once the LNAPL gauging is complete, Kleinfelder will use weighted disposable bailers to remove the
LNAPL from each well. Complete removal of LNAPL from each well is not practicable, therefore
Kleinfelder will document the LNAPL thickness remaining following removal. Waste generated from
LNAPL purging will be placed into a 55-gallon steel drum which will be picked up for disposal on the
same day as the purging activities, eliminating the need for waste storage at the Site.

Kleinfelder personnel will return to the Site approximately 1, 2, 4, and 8 weeks from the initial LNAPL
removal to gauge depths to LNAPL and groundwater in the ten groundwater monitoring wells listed in
Table 2. Kleinfelder will use LNAPL gauging data to evaluate LNAPL recovery at the Site, which will then
be used to inform future remedial design.

Task 4 – Data Evaluation and Reporting

Groundwater monitoring and LNAPL recovery data obtained during our investigation will be reviewed,
evaluated, and a report will be prepared documenting the results of the monitoring activities. The report
will include a summary of the field methods used, field observations, figures, and analytical results
compared to DERR ISLs and Tier 1 Screening Criteria, as appropriate. Kleinfelder will also include
updated historical data tables for the Site. One electronic copy of the report will be provided to DERR no
later than ten business days following the eight-week LNAPL gauging event.

ESTIMATED PROJECT FEE

A detailed cost itemization for each task described above is presented as Attachment B. The estimated
costs to complete the work described above are $18,470.65. The work will be performed, and payment
for completed tasks will be made, according to the terms and conditions of our existing Master Services
Contract #216378.

ASSUMPTIONS

Our proposed scope of services is based on the following assumptions:

• MW-25 will not be sampled since benzene, TPH-GRO, and TPH-DRO concentrations were not
reported by the laboratory during the December 2022 groundwater monitoring event. MW-25 is
located in the left turn lane in Center Street and would require a permit from the City of Midvale
and traffic control to temporarily close the turn lane.
• All wells will be accessible and in adequate condition for sample collection and no well
development will be required to collect representative samples.
• The groundwater sampling and well repair activities can be completed in three ten-hour field
days.
• The initial LNAPL gauging and purging can be completed in one ten-hour field day.
• Kleinfelder does not need access agreements with private property owners to sample and purge
groundwater monitoring wells.
• Purged groundwater will be spread on a non-permeable surface and allowed to evaporate. No
costs have been included in this Workplan and Price for investigation derived waste
groundwater storage, characterization, or disposal.
• Waste LNAPL will be picked up on the same day as the LNAPL purging, therefore, no waste
storage will be required.
• One electronic copy of the report shall be forwarded to DERR. No hard copies are included in
our scope of services. Client meetings, revisions, and any work following the submittal of the
report are not included in the budget estimate but can be provided on a time-and-materials
basis.
• Samples submitted for laboratory analysis will be conducted on a standard turnaround time. No
rush fees are included in our proposal.
• Subcontractor fees will be marked up 10 percent.
• Kleinfelder may not be able to secure the three access agreements for the residential properties
with the budget included in this Workplan and Price. In this case, the scope may need to be
modified (fewer or different sample locations), or an additional fee may be required to continue
efforts to obtain legal access to the properties proposed for vapor sampling.

LIMITATIONS

Our work will be performed in a manner consistent with that level of care and skill ordinarily exercised
by other members of Kleinfelder’s profession practicing in the same locality, under similar conditions
and at the date the services are provided. Our conclusions, opinions, and recommendations will be
based on a limited number of observations and data. It is possible that conditions could vary between or
beyond the data evaluated. Kleinfelder makes no guarantee or warranty, express or implied, regarding
the services, communication (oral or written), report, opinion, or instrument of service provided.

The Client should be aware that penetrating the ground surface is inherently risky and it is impossible to
determine with certainty the precise location of all utilities and/or structures that may be buried in the
ground. Kleinfelder's fee is not adequate to compensate for both the performance of the services and
the assumption of risk of damage to such structures or encountering obstructions from buried debris in
the fill covering the site. Although Kleinfelder will make all reasonable effort to avoid damage to utilities,
disruption of utilities or damage to underground structures will be the responsibility of the Client.
Services rendered by Kleinfelder to repair them will be billed at cost.

During the course of the performance of Kleinfelder's services, hazardous materials may be discovered.
Kleinfelder will assume no responsibility or liability whatsoever for any claim, loss of property value,
damage, or injury that results from pre-existing hazardous materials being encountered or present on
the project site, or from the discovery of such hazardous materials.

Orders or restrictions issued by civil authorities and other conditions relating to the COVID-19 pandemic
may interfere with Kleinfelder’s ability to perform or otherwise impact our ability to work. Kleinfelder
will communicate any anticipated delays or impacts and work closely with the client to identify a
mutually acceptable solution to advance Kleinfelder’s completion of its services.

AUTHORIZATION

If our proposed scope of services and fee meet your needs, please provide a Work Assignment for the
activities.
