1.0 INTRODUCTION

EarthTouch, Inc. conducted a Limited Subsurface Investigation (LSI) of a light-industrial property located
at 1218 East 135 South (Street) in the city of Vernal, (Uintah County), Utah (“subject property” or “site”).
The LSI was performed for Davis East & West, LLC as part of the environmental due diligence related to
a possible transfer of ownership. The LSI was authorized by representatives of Davis East & West, LLC
and performed in general accordance with the Scope of Work outlined in an Engagement Letter included
as Attachment 1.

A Phase I Environmental Site Assessment (ESA) of the subject property (23-Mar-2023) identified
recognized environmental conditions associated with the use of the site for a machine shop for roughly 45
years; the presence of several 55-gallon drums of petroleum products, and the presence of machining
presses with 10- to 40-gallon hydraulic fluid reservoirs. Additionally, the subject property is located in an
industrial area including a former generator of hazardous waste situated in up-gradient position relative to
the site.

1.1 Site Description

The subject property is a rectangular-shaped tract of land encompassing roughly 2.02 acres improved with
a block-masonry and frame-constructed office-warehouse with a lean-to shed, gravel-covered lay-down
yard with overhead racking system, and asphalt-paved area for vehicle parking along with a partial
perimeter chain-link fence. The office-warehouse is rectangular-shaped, roughly 40- by 110-feet,
oriented north-south on the north-central part of the site with a rectangular-shaped addition on the east
that is about 25- by 80-feet. The office-warehouse is block-masonry constructed on a slab-on-grade
foundation with an interior clear-height of about 13 feet and sloping metal roof of average pitch. Offices,
reception area, storage rooms, and restrooms are situated in the northern part of the building within a
frame-constructed addition with primary pedestrian access centrally located on the northern elevation.
Remaining areas of the structure include three work areas separated by block-masonry walls with garage-
door and man-door accesses on the eastern, southern, and western elevations. The southern portion of the
office-warehouse includes an overhead crane to provide for the movement of metal products. There is
mezzanine storage above the office area. An open-air lean-to shed is situated roughly midway along the
eastern elevation of the office-warehouse and enclosed by wire-fence for secure storage. An asphalt-
paved area runs along the northern edge of the site extending from the office-warehouse to 135 South that
provides for vehicle parking. Immediately south of the office-warehouse is an overhead metal pulley
system that provides for the movement of metal parts and pieces. Remaining areas of the site are covered
with gravel and previously used for storing metal parts and pieces and products. A large mound of gravel
and snow was situated on the south part of the site.

1.2 Background

The Phase I ESA identified the following recognized environmental conditions:

 The office-warehouse on the subject property was originally constructed in the early to middle 1970s
and since constructed has been occupied by Stewart Machine & Welding, Inc., a machine shop
involved in fabricating, repairing, and remodeling oil field equipment and related parts. The business
operations of a machine shop at the subject property included the use of hydraulic fluids, motor oils,
cutting fluids, Stoddard solvent, and other petroleum products, generally in bulk; and resulted in
notable staining of concrete foundation extending to cracks and/or seams, and notable petroleum
odor. As such, the historical use of the subject property as a machine shop for roughly 45 years is
considered a recognized environmental condition for the site.

 There are about 4 or 5 self-contained machining units with integrated spill-trays to capture cutting
oils, hydraulic fluids, and coolants used in metal-working processes; several of these units have
reportedly been sold and will be removed from the site. At the time of the site inspection, the
reservoirs of the machining units were emptied with only small residual volumes noted. When
operational, the reservoirs for hydraulic fluids, cutting oils, and/or coolants appeared to generally
contain from roughly 10 to 40 gallons. Screening systems were reportedly previously used to remove
metal shavings and chips, which were conveyed to a metal bin adjacent to the southern elevation of
the building with residual oil drained into a used oil container. The presence of machining units on
the subject property poses a moderate to high concern of adverse impact to the environmental
condition of the site given the notable staining in and around the machining units and obvious
petroleum odor within warehouse areas.

There was notable staining of the concrete flooring in the warehouse in areas adjacent to some of the
machining units along with some deployment of absorbent. Reportedly, the concrete floor was steam
cleaned in advance of the site inspection. However, the concrete flooring remained ‘heavily stained’,
and the stained areas were noted to extend to cracks and seams in the concrete, which would be a
recognized environmental condition for the subject property due to the potential for the migration of
petroleum products to the subsurface through cracks and seams over the 40+ years of operation of the
machine shop at the site.

 There are three 55-gallon drums, which are stored in separate parts of the warehouse and used
primarily for operating machining units, as well as one ~300-gallon tote of used oil and water situated
in the storage yard to the south of the building. Two of the 55-gallon drums are equipped with hand-
pumps for dispensing and are situated adjacent to interior walls. The used oil tote was about one-fifth
full and used oil is reportedly collected by Reinhart Oil for recycling.

The presence of the tote and 55-gallon drums of petroleum products would be a recognized
environmental condition for the subject property due to the material threat of a spill(s) or release(s) in
volume(s) in excess of the reportable quantity (RQ). However, the material threat of a spill(s) and/or
release(s) is diminished by storage in areas of the site generally protective of strike, upset, and/or
puncture, but, the material threat of a spill(s) or release(s) is amplified by notable staining of the
concrete flooring within warehouse areas that extended to cracks and seams in the foundation and
storage of the tote outside without secondary containment.

Some additional comments / environmental concerns associated with the subject property that do not meet
the definition of a recognized environmental condition, but may or may not be considered as business
environmental risks associated with the site, included:

 The presence of machining units on the subject property poses a moderate to high concern of adverse
impact to the environmental condition of the site given the notable staining in and around the
machining units and obvious petroleum odor within warehouse areas.

 The former Western/Simmons Petroleum waste oil facility at 1157 East 135 South roughly 400 feet to
the west-northwest of the site in an up-gradient location with respect to the site is listed on regulatory
agency databases as a former generator of hazardous waste with numerous violations related to
generating, transporting, and/or transferring used oil; failing to meet permit requirements; applying
used oil as a dust suppressant; and using ‘off-spec’ burners for recycling used oil. This facility is
situated in an up- to cross-gradient position relative to the site with groundwater in the site vicinity
generally encountered at depths of 3 to 8 feet bgs posing a moderate concern of adverse impact to the
environmental condition of the subject property.

More detailed information is reported in the Phase I Environmental Site Assessment of a Light-Industrial
Property Located at 1218 East 135 South (Street) in the city of Vernal, (Uintah County), Utah.

1.3 Objectives and Scope of Work

The objectives of the LSI were to evaluate soil and/or groundwater at the site for the potential presence of
volatile organic compounds (VOCs), total petroleum hydrocarbon (TPH) as diesel range organics (DRO),
oil and grease (O&G), and RCRA 8 Metals (arsenic, barium, cadmium, chromium, lead, mercury,
selenium, silver).

The Scope of Work included:

 Advancing six subsurface borings to up to 20 feet below ground surface (bgs);
 Collecting one soil sample from each boring;
 Collecting one groundwater samples from each boring:
 Analyzing specific collected samples for VOCs, TPH-DRO, O&G, and/or RCRA 8 Metals;
 Groundwater samples were analyzed for dissolved RCRA 8 Metals: and
 Preparing a summary report of activities and analytical results.

Boring and sampling locations were based on the review of the present-day conditions and historical
information from the Phase I ESA, surface features, estimated groundwater gradient, adjoining property
uses, underground and overhead utilities, and vegetation, as well as equipment accessibility.

A generalized layout of the site and boring locations are shown in Figure 3 and described below:

 Boring B-1: Interior of the building in the eastern work area;
 Boring B-2: Interior of the building in the southern work area in;
 Boring B-3: South end of the exterior overhead crane system adjacent to the used oil tote and
former aboveground storage tank;
 Boring B-4: Southeast of the exterior lean-to on the eastern building elevation.

2.0 ENVIRONMENTAL SETTING

Descriptions of the environmental characteristics and physical setting of the subject property are based
upon a reconnaissance of the site and review of readily available information.

2.1 Topography

Vernal is located in the Ashley Valley of northeastern Utah, which is bordered by the Uinta Mountains to
the north, Blue Mountain to the east, and the Book Cliff Mountains to the south. Terrain in the general
area is variable and includes relatively flat valley areas, gently sloping alluvial fans, isolated knolls, and
plateaus that extend southward from the Uinta Mountains onto the valley floor. Major rivers and streams
include Ashley Creek, White River, Uinta River, and Green River. The lowest elevation in the general
area is about 4,040 feet above mean sea level (amsl) along the Green River in the southeastern part of the
Ashley Valley with elevation increasing gradually to the west and northwest toward the foothills of the
Uinta Mountains. The US Geological Survey 7.5-minute Quadrangle Map of the general area (Vernal
NE, Utah) depicts the site vicinity as relatively flat terrain that slopes gently to the east at an average
elevation of approximately 5,250 feet amsl. The natural elevation across the site is about 2 to 3 feet.

2.2 Geology and Soils

Vernal is in the Uinta Basin, which is a subpart of the Colorado Plateau physiographic province that is
characterized by broad plateaus or tablelands, ancient volcanic mountains, and deeply dissected canyons.
The Uinta Basin covers roughly 10,000 square miles of northeastern Utah and northwestern Colorado
generally bordered by the Uinta Mountains to the north, the west slope of the Rocky Mountains to the
east, the Book and Roan Cliffs to the south, and the Wasatch Plateau to the west. The Uinta Basin is a
structural trough containing a thick succession (up to 30,000 feet) of Tertiary lacustrine and fluvial
sediments with a sharply asymmetrically steep northern flank and a relatively gently dipping southern
flank. Deposits generally consist of open to marginal lacustrine and fluvial sediments that dip gently
northward. The site resides on alluvium over the Duchesne River and Uinta Formations that consist of
interbedded red, brown, and variable colored clay-shales; gray to buff red weathering sandstones, and
some conglomerates of fluvial origin derived from the Uinta Mountains; and gray-green gypsiferous
clays, shales, sandstones, and mudstones. Alluvium in the site vicinity consists of unconsolidated to
moderately consolidated, poorly sorted sand, gravels, cobbles, and boulders deposited on near-planar
surfaces that are typically less than five feet in thickness.

The Natural Resources Conservation Service identified soils at the site as Blackston, Crib, and Wyasket
loam in the Soil Survey of Uintah Area-Parts of Daggett, Grand and Uintah Counties, Utah. These soils
are very deep, well drained soils formed in alluvium and slope alluvium that may be underlain by
residuum derived from mixed sources; and are found on the edges of old high terraces, on fan remnants,
and on structural benches with slopes ranging from 0 to 40 percent at elevations of 4,900 to 6,300 feet
amsl on the western slope of Colorado and adjoining parts of eastern and central Utah. These soils have
negligible to high runoff and moderate permeability.

2.3 Surface Water

The site is in the Ashley Creek drainage, which encompasses roughly 395 square miles and is generally
bordered by the Uinta Mountains to the north, Buckskin Hills to the east, and Asphalt Ridge to the west.
Ashley Creek rises in the Uinta Mountains and flows more or less southeasterly about 45 miles before
emptying into the Green River near Jensen, Utah. Land use within the Ashley Creek drainage is
predominantly forest in the upper portions of the watershed and agricultural land uses dominating the
lower portions of the watershed. Communities in the Ashley Creek drainage include Vernal, Naples,
Maeser, and Jensen. Ashley Creek is a perennial stream; however, many tributary streams along the

Davis East & West, LLC
Limited Subsurface Investigation 5
Former Stewart Machine – Vernal, Utah
southeastern slopes of the Uinta Mountains are ephemeral creeks and arroyos that flow during spring
runoff and discharge of irrigation water. The subject property is located in an area crossed by ephemeral
streams and drainage canals that flow easterly toward Ashley Creek, which flows south-southeasterly
about a mile to the east of the site. Surface water at the site would sheet flow to the east and southeast
toward a drainage ditch along the southern edge of the subject property.

2.4 Groundwater

Groundwater hydrology of the Uinta Basin is controlled by the geologic structure of the region.
Variations of aquifer and aquitard permeability are associated with differences of lithology. The general
pattern of groundwater gradient is centripetal, flowing inward from recharge areas along the margins of
the Uinta Basin toward the central part of the Ashley Valley. Recharge is typically greatest along the
northern margin of the Uinta Basin. Within the site vicinity, shallow groundwater is contained within
alluvial sediments and is encountered at depths of about 4 to 8 feet below ground surface (bgs) with
seasonal variation. Shallow groundwater gradient in the site vicinity is estimated to be east-southeasterly
following the trend of local topography toward Ashley Creek.

3.0 FIELD INVESTIGATION

On 7-Apr-2023, four direct-push borings were advanced at the site. Prior to conducting field activities,
the presence of underground utilities was further inspected, marked, and cleared through Utah Bluestakes.
Ms. Eve Dunn of EarthTouch, Inc. performed soil logging, collected soil and/or groundwater samples,
and observed boring advancement and abandonment activities. At each boring location, soil samples
were collected using a direct-push drill-rig operated by RMEC Environmental, Inc. of Bountiful, Utah.

3.1 Direct-Push Soil Borings and Sampling

Borings were advanced approximately up to depths of up to 15 feet bgs, generally where equipment
refusal was encountered, using a track-mounted direct-push drill-rig. Soil samples were continuously
collected using a two-inch diameter sampling probe edged with disposable liners driven through the
subsurface by hydraulic hammer. Soil samples were collected in disposable liners in up to 5-foot
intervals, which were then removed from the probe and opened for inspection. Collected soil samples
were physically evaluated, logged, and examined for visual and olfactory evidence of impact.
Groundwater was encountered at depths of 7.5 to 10 feet bgs at the site.

Sample depths were determined by the physical inspection of each boring as specified below:

 B-1A: soil sample, collected at 1 to 2 feet bgs (analyzed for O&G, VOCs); and
 B-1W: groundwater sample, collected at ~10 feet bgs (analyzed for O&G, VOCs).

 B-2A: soil sample, collected at 1 to 3 feet bgs (analyzed for TPH-DRO, O&G, VOCs); and
 B-2W: groundwater sample, collected at ~10 feet bgs (analyzed for TPH-DRO, O&G, VOCs).

 B-3A: soil sample, collected at 0.5 to 2.5 feet bgs (analyzed for TPH-DRO, O&G, VOCs,
RCRA 8 Metals); and
 B-3W: groundwater sample, collected at ~7.5 feet bgs (analyzed for TPH-DRO, O&G, VOCs,
dissolved RCRA 8 Metals)

 B-4A: soil sample, collected at 1 to 2.5 feet bgs (analyzed for TPH-DRO, O&G, VOCs,
RCRA 8 Metals); and
 B-4W: groundwater sample, collected at ~9 feet bgs (analyzed for TPH-DRO, O&G, VOCs,
dissolved RCRA 8 Metals).

Limited Subsurface Investigation 6
Former Stewart Machine – Vernal, Utah

A physical description of the soil types encountered was recorded on boring logs in general accordance
with the Unified Soils Classification System. Near surface deposits were observed to consist
predominantly of sand with varying amounts of silt and gravel. Groundwater at the site was encountered
at depths of 7.5 to 10 feet bgs during field activities. Boring logs depicting the subsurface lithology
beneath the subject property at the selected drilling locations are included as Appendix A.

Samples were placed in new, clean containers provided by the analytical laboratory, in a manner that
minimized air pockets or headspace. Each sample container was labeled with the site name, sample
designation, and date/time of sampled collection and subsequently positioned in a rigid cooler filled with
ice and chilled to approximately 4°C (Celsius) for transport to the analytical laboratory.

At the conclusion of sampling activities, the borings were backfilled with soil cuttings and hydrated
bentonite chips and capped with asphalt, concrete, or soil to match the existing grade.

4.0 LABORATORY TESTING

A Chain-of-Custody was completed for the soil and groundwater samples collected during this
investigation and were subsequently delivered under chain-of-custody protocols to Pace Analytical
Laboratory (Pace) in Mount Juliet, Tennessee. Pace is certified and accredited to perform analysis of soil
and groundwater samples for the presence of VOCs, TPH-DRO, O&G, and RCRA 8 Metals. Collected
samples were analyzed for the presence of VOCs using EPA Method 8260B, TPH-DRO using EPA
Method 8015, O&G using EPA Method 9071B, and RCRA 8 Metals 7470A/7471A/6010B.

Copies of the laboratory report and Chain-of-Custody are attached as Appendix B.

5.0 SUMMARY OF RELEVANT FINDINGS

The following findings are based upon field observations and measurements, review of analytical data,
comparison of analytical results with applicable regulatory levels, and comparative evaluation of
contaminant concentrations with known environmental conditions of the surrounding area.

5.1 Field Investigation Findings

The following findings are based upon field observations and measurements:

 Soils encountered at the subject property consisted predominantly of sand with varying amounts of
silt and gravel.

 No significant subsurface evidence of impacted soils such as significant visible staining or olfactory
indications were noted during drilling activities, with the exception of shallow soils in boring B-2.

 Groundwater was encountered at the site from 7.5 to 10 feet bgs.

Davis East & West, LLC
Limited Subsurface Investigation 7
Former Stewart Machine – Vernal, Utah
5.2 Laboratory Results

Analytical results for soil samples collected from this investigation are summarized in Table 1.

 Laboratory analysis of the samples collected at the subject property identified TPH-DRO, O&G, 13
VOCs, and six RCRA 8 Metals at concentrations above the laboratory limit of detection (LLD).

The reported concentrations of the analytes detected in samples at levels above the LLD were
compared to the following:

- Utah Department of Environmental Quality (DEQ), Utah Leaking Underground Storage Tank
(LUST) Program Screening Levels for Soil and Groundwater, Initial Screening Levels (ISLs).

- US Environmental Protection Agency (EPA), Regional Screening Levels (RSLs), Resident Soils
and Industrial Soils, Nov-2022.

Review of the analytical data for the samples collected at the site suggests the following:

 TPH-GRO, TPH-DRO, O&G were identified above the LLD in multiple soil and groundwater
samples at the subject property, but the reported concentrations were less than the respective ISLs for
unrestricted use.

 There were eight VOCs found above the LLD in the soil samples from the subject property.
However, none of the detected VOCs exceeded the referenced regulatory standards, with the
exception of p-isopropyltoluene, for which no standard was listed. Four VOCs were detected in the
groundwater samples from the site. But only tetrachloroethene (PCE) was reported at concentrations
exceeding the referenced regulatory standard in three groundwater samples.

 Four of the eight metals were found above the LLD in soil samples. Of the detected metals (arsenic,
barium, chromium, and lead), only arsenic exceeded the referenced regulatory standards. The RSL
for chromium III was used to evaluate the reported concentrations of total chromium as there were no
known sources of anthropogenic chromium at the site. All detected levels of arsenic exceeded the
RSL for unrestricted use and the one sample (and 3.64 milligram per kilogram [mg/kg]) and B-3
(3.64 mg/kg) exceeded the RSL for industrial use (3 mg/kg).

The detected concentrations of arsenic in soil at the site were from 2.12 to 3.64 mg/kg, which exceeds
the RSL for unrestricted (residential) use (0.63 mg/kg) with the majority of arsenic concentrations in
soil also exceeding the RSL for industrial use (3 mg/kg). The reported levels for arsenic were also
compared to background soil concentrations included in the Element Concentration in Soils and
Other Surficial Materials of the Conterminous United States as US Geological Survey, Professional
Paper 1270 by Hansford T. Shacklette/Josephine G. Boerngen. The background concentrations for
arsenic in soils in the general area of the subject property were identified at a mean concentration of
5.5 mg/kg with an observed range of <0.10 to 97 mg/kg and an average local concentration of 4.1 to
6.5 mg/kg. In the Geochemical Landscapes of the Conterminous United States–New Map
Presentation for 22 Elements, US Geological Survey, Professional Paper 1648 authored by N.
Gustavsson, B. Bolviken, D. B. Smith, and R. C. Severson; the background concentrations of arsenic
in soil in the general area of the site reportedly ranges from 4.7 to 6.3 mg/kg. The detectable
concentrations of arsenic identified in soils at the subject property were generally within the reported
background concentrations for southeastern Utah and the area of the subject property.

Davis East & West, LLC
Limited Subsurface Investigation 8
Former Stewart Machine – Vernal, Utah
Six metals (arsenic, barium, cadmium, chromium, lead, and selenium) were detected at concentrations
above the LLDs in some or all of the groundwater samples analyzed. The reported concentrations of
barium, cadmium, chromium, lead, and selenium were less than RSLs. The concentrations of arsenic
in one of the two groundwater samples (B-4) slightly (11.1 micrograms per liter [µg/l]) exceeded the
RSL (10 µg/l); arsenic was below the LLD in the other groundwater sample.

6.0 CONCLUSIONS

Based upon the data collected during the Phase I ESA and the field investigation of the subject property,
the following conclusions have been developed:

 Davis East & West, LLC is considering a financial transaction involving the site and requested this
subsurface investigation to evaluate the potential of adverse impact to the environmental condition of
the subject property related to past/present operations at the site, historical uses of the site, and/or
possible off-site impacts from business operations on adjoining/nearby properties. The investigation
was performed to address recognized environmental conditions and other areas of concern identified
in a Phase I ESA as a part of the environmental due diligence of the subject property. Sample
locations were selected based on information obtained during a Phase I ESA, interview with
personnel familiar with the site, physical conditions, and access limitations of the subject property.
The analytical results and laboratory analysis are limited to the locations sampled during this
investigation.

 Soils encountered at the subject property consisted predominantly of sand with varying amounts of
silt and gravel and groundwater was encountered at depths from 7.5 to 10 feet bgs. No significant
subsurface evidence of impacted soils such as significant visible staining or olfactory indications were
noted during drilling activities, with the exception of shallow soils in B-2.

 Laboratory analysis of the samples collected at the site identified TPH-DRO, O&G, 13 VOCs, and six
RCRA 8 Metals at concentrations above the LLDs. However, none of the detected concentrations of
TPH-DRO and O&G in the soil and groundwater samples; or VOCs in the soil samples exceeded the
referenced regulatory standards.

PCE was detected in three groundwater samples from B-1, B-2 and B-4 at concentrations that
exceeded the referenced regulatory standards. These borings were located within former work areas
of the building and immediately to the east of the building. Based on the information obtained from
this investigation, PCE may have been used in routine machining operations and migrated to the
subsurface through cracks, seams, or pitted areas of the concrete floor during historic use at the
subject property. However, an up-gradient groundwater sample was not collected, and given
historical uses within the site vicinity there may be a possibility of contaminant contribution from off-
site sources to the east and northeast of the subject property.

Metals were detected in soil samples collected from the site. However, only arsenic was found to
exceed the referenced regulatory standards. But the reported concentrations of arsenic in soil samples
from the subject property were within the published background concentrations for the general area of
the site. Metals were also detected in groundwater at the site, with only arsenic slightly exceeding the
referenced regulatory standard in the groundwater sample from the boring east of the building; this
exceedance may be related to excessive turbidity at this location.

 Given the identified concentrations of the above discussed contaminants of concern above the
referenced regulatory standards would likely be considered a ‘reportable condition’ requiring
notification of the Utah Department of Environmental Quality (DEQ). Notification of the Utah DEQ

Davis East & West, LLC
Limited Subsurface Investigation 9
Former Stewart Machine – Vernal, Utah
prior to any transfer of ownership of or financial transaction involving the subject property and due to
the identified contaminant impact, there may be a ‘discount’ to the appraised value of the site.

Additionally, it is suggested that an application for Enforceable Written Assurance (EWA) be
prepared and submitted for the site to the Utah DEQ as a bona-fide prospective purchaser prior to any
acquisition of the site or any change of ownership of the subject property resulting in Davis East &
West, LLC or related entity being vested in title, or part of any long-term lease agreement; it should
be noted that the EWA process can take more than 60 days to complete. Through consultation with
the Utah DEQ, the EWA would define any reasonable steps to address the existing contaminant
conditions at the subject property such that the Utah DEQ would not initiate an enforcement action
against the subject property or new owner of the site.

In order to define reasonable steps, it may be necessary to perform additional investigation of the
subject property to better characterize contaminant conditions with respect to the anticipated future
residential use. Alternatively, there may be an option for ‘Conditional EWA’ that would involve
application for EWA ‘conditioned’ upon entry into the Voluntary Cleanup Program (VCP)
subsequent to acquisition of the subject property; which following characterization and mitigation
activities would provide for a Certificate of Completion that ‘runs with the land’ and would be
transferable to future owners of the subject property and/or subsequent ‘daughter parcels’ created
through subdivision of the site.

7.0 LIMITATIONS

This project was performed using, as a minimum, practices consistent with the standards acceptable
within the industry at the time of the evaluation, and a level of diligence typically exercised by
environmental consultants performing similar services. The methods used in the performance of this
scope of work were presented to and/or discussed with representatives of Davis East & West, LLC prior
to initiating field activities. These methods may have been altered in the field as a result of actual site
conditions. The procedures used attempt to establish a balance between the competing goals of limiting
investigative sampling and reporting costs and reducing uncertainty about known field conditions. It is
possible that unexpected subsurface conditions could be encountered in areas that were not physically
sampled. Therefore, because the conditions of this report were derived from the scope of work, costs,
time, access and other limitations, the conclusions should not be construed as a guarantee that all
environmental liabilities have been identified and fully addressed.

This report presents the opinion and judgment of EarthTouch, Inc. professionals, which are dependent on
the information obtained during the performance of the scope of work. It should be noted that no
investigation can be thorough enough to exclude the possible presence of potential liabilities at a site. In
cases where contaminants have not been discovered through intrusive exploration and analysis, this
should not be construed as a guarantee that contaminants do not exist. At a given site, environmental
conditions may exist that cannot be identified by visual observations or through other analytical
methodology. Where sample collecting and testing have been performed, EarthTouch, Inc. professional
opinions are based in part on the interpretation of data from discrete sampling locations that may not
represent conditions at unsampled locations or the subject property as a whole. EarthTouch, Inc. assumes
no responsibility for omissions or errors resulting from inaccurate information, or data provided by
secondary sources or public records.

RE: Scope of Work/Cost Estimate for a Limited Subsurface Investigation (LSI) of a light-industrial
property located at 1218 East 135 South (Street) in Vernal, (Uintah County), Utah.

Dear Mr. Davis

EarthTouch, Inc. is pleased to present Davis East& West, LLC with this Scope of Work/Cost Estimate to
perform a Limited Subsurface Investigation (LSI) of a light-industrial property located at 1218 East 135
South (Street) in Vernal, (Uintah County), Utah (“site” or “subject property”). The Scope of Work/Cost
Estimate was prepared in response to the findings of a Phase I Environmental Site Assessment (ESA) by
EarthTouch, Inc. completed on 23-Mar-2023 that identified recognized environmental conditions and
areas of concern (AOCs) related to the use of the site for a machine shop for roughly 45 years; the
presence of several 55-gallon drums of petroleum products, and the presence of machining presses with
10 to 40 gallon hydraulic fluid reservoirs. Additionally, the site is located in an industrial area including
an up-gradient generator of hazardous waste.

The subject property is a rectangular-shaped tract of land encompassing roughly 2.02 acres improved with
a block-masonry and frame-constructed office-warehouse with a lean-to shed, gravel-covered lay-down
yard with overhead racking system, and asphalt-paved area for vehicle parking along with a partial
perimeter chain-link fence. The office-warehouse is rectangular-shaped, roughly 40- by 110-feet,
oriented north-south, and block masonry constructed on a slab foundation on the north-central part of the
site with a rectangular-shaped addition on the east that is about 25- by 80-feet. Offices, reception area,
storage rooms, and restrooms are situated in the northern part of the building within a frame-constructed
addition. Remaining portions of the building include three work areas separated by block-masonry walls
with garage-door and man-door accesses on the eastern, southern, and western elevations. The southern
portion of the office-warehouse includes an overhead crane to provide for the movement of metal
products. An open-air lean-to shed is situated roughly midway along the eastern elevation of the office-
warehouse and enclosed by wire-fence for secure storage. An asphalt-paved area runs along the northern
edge of the site extending from the office-warehouse to 135 South that provides for vehicle parking.
Immediately south of the office-warehouse is an overhead metal pulley system that provides for
movement of metal parts and pieces. Remaining areas of the site are covered with gravel and previously
used for storing metal parts and pieces and products.

Review of historical information indicated the subject property and adjoining properties were developed
with agricultural land uses by the early 1950s, which continued into the early 1970s. The original portion
of the office-warehouse on the subject property was constructed by 1976. In the early 1990s, the office

Davis East & West, LLC
Limited Subsurface Investigation 2
Davis East & West, LLC – Vernal, Utah
and warehouse additions to the north and east of the original office-warehouse were constructed. Since
constructed, the tenant at the subject property has been Stewart Machine & Welding, Inc., a machine shop
involved in fabricating, repairing, and remodeling oil field equipment and related parts though it had not
been used for roughly the past two years

SCOPE OF WORK

The Scope of Work would include the following tasks.

LSI Pre-Field Activities – Underground Service Alert/Site Specified Health & Safety Plan

A public utilities location service would be contacted to identify the position(s) of public utilities,
including; electrical, natural gas, water, cable television, and/or other utilities as well as some subsurface
man-made features such as sewers, septic systems, and secondary water connections that may be located
on the site or within identified easements. Access to the exterior of the subject property, including fenced
areas, would need to be available to provide access for utility locate personnel. EarthTouch, Inc. and
subcontractors are not responsible for locating or any damage to private utilities or other subgrade
features not identified through public utility locate services.

A site-specific safety and health plan (SSHP) would be prepared to provide an overview of the potential
hazards associated with proposed subsurface investigation activities. The SSHP would identify the
contaminants of concern, potential site safety hazards, conditions for which the use of protective
equipment would be necessary, and the appropriate health and safety measures to be implemented when
performing field activities at the site.

Advancing LSI Borings and Collecting / Analyzing Samples

Based on the available information, up to four borings would be advanced at the subject property to
collect and analyze soil and groundwater samples using a truck- or track-mounted direct-push drill-rig
with 4- or 5-foot segments extending to depths up to 15 feet below ground surface (bgs). Soil segments
would be inspected, physical features and attributes logged, and the soil examined for evidence of
contaminants, including; discoloring, smudging, staining, and/or olfactory indications.

Samples would be collected by the Project Geologist and placed in laboratory-prepared glassware,
positioned within rigid containers and cooled to 4° Celsius (C) and then transported to an analytical
laboratory certified by the State of Utah and/or accredited through the National Environmental Laboratory
Accreditation Program (NELAP). Soil samples would be prepared and transported in a manner consistent
with US Environmental Protection Agency (EPA) and/or Utah Department of Environmental Quality
(DEQ) protocols for the analyses to be performed and transported under Chain-of-Custody procedures.

Groundwater in the site vicinity is estimated to be less than 15 feet bgs. If groundwater is encountered,
well-point groundwater samples would be collected using new, dedicated tubing and placed directly into
laboratory-prepared glassware consistent with the type of analysis to be performed, positioned within
rigid containers prepared with ice and/or contained coolant, chilled to 4°C, and transferred to analytical
laboratory under chain-of-custody procedures. Development of the borings as temporary groundwater
monitoring wells is not contemplated as a part of field activities or part of this Scope of Work.

At the conclusion of field activities, the borings advanced at the subject property would be abandoned by
backfilling with soil cuttings and hydrated bentonite chips, and then capped with asphalt, concrete, gravel,
or soil similar to the surrounding grade.

Davis East & West, LLC
Limited Subsurface Investigation 3
Davis East & West, LLC – Vernal, Utah

EarthTouch, Inc. and subcontractors are not responsible for damage to private, unmarked, and/or
inadequately marked utilities.

Laboratory Analysis – Soil and/or Groundwater Samples

Although all samples collected in the field may not be analyzed, all samples would be transported to the
analytical laboratory for analysis. Based on environmental concerns associated with the subject property
and the proposed sample locations, soil and groundwater samples would be analyzed, as appropriate, for
the potential presence of the following:

- Volatile Organic Compounds (VOCs);
- Total Petroleum Hydrocarbons (TPH) as diesel range organics (DRO);
- Oil and Grease (O&G); and/or
- RCRA 8 Metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver).

Laboratory analysis would be on a ‘rush’ basis with roughly 2 to 3 business day turn-around time, after
receipt of the samples by the laboratory. The analytical laboratory would provide an analytical report for
all sample analysis along with applicable standard quality assurance and quality control data.

Data Compilation and Report Generation

EarthTouch, Inc. personnel would evaluate the data gathered from the above tasks and prepare a report
documenting and summarizing relevant findings, present physical conditions, and observations regarding
the presence or absence of contaminants of concern in soil and groundwater at the site. The report
summarizing the site investigation would include:

- An outline of sampling methods and data gathered during the environmental investigation;
- A site plan that identifies building locations and other site structures/features, boring/sampling
locations, and contaminants of concern (COCs) identified through collecting and analyzing soil
samples; and
- A summary of field activities, analytical results, and evaluation and opinion regarding the
environmental conditions identified and the potential implications related to any identified soil and/or
groundwater impacts (if any).

EarthTouch, Inc. would provide an electronic copy of the report to Davis East& West, LLC. However, no
additional actions beyond preparation of the report would be carried out by EarthTouch, Inc. without prior
authorization.

SCHEDULE

We anticipate that field activities could be completed within about one to two weeks, contingent on the
prompt authorization and availability of a drilling company to mobilize to the site and site access.
Laboratory analysis would be completed on a standard 10-business day (2-week) turn-around basis upon
the completion of the field activities. A report summarizing field activities, analytical results, and other
findings of the investigation would be prepared within approximately one week of the receipt of
analytical data.

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
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit.
