Brownfields Assessment Work Plan
Harrelson Ford
6500 South Boulevard
Charlotte, North Carolina
H&H Job No. ACO-002
1.0 Introduction
On behalf of TAC Harrelson Ford, LLC, Hart & Hickman, PC (H&H) is providing this
Brownfields Assessment Work Plan (Work Plan) for the Harrelson Ford property located at 6500
South Boulevard in Charlotte, Mecklenburg County, North Carolina (Site). A Site location map
is provided as Figure 1, and the Site and surrounding area are shown in Figure 2.
The Site consists of one parcel (Mecklenburg Parcel ID No. 17304204) that totals approximately
10.6 acres of land located in a mixed light industrial, commercial, and residential use area
approximately five miles south of uptown Charlotte. The northern portion of the Site is
developed with an unoccupied approximate 2,000 square foot (sq ft) warehouse (Building 1), an
approximate 9,300 sq ft service garage (Building 2), an unoccupied approximate 20,000 square
foot (sq ft) vehicle showroom and service garage (Building 3), and one unoccupied approximate
14,000 sq ft service garage (Building 4). Remaining portions of the Site consist of paved access
drives, parking areas, and equipment material staging areas. The Site buildings are shown in
Figure 2.
Proposed redevelopment of the Brownfields property includes razing the existing Site buildings
and leveling the Site for construction of approximately 175 townhome buildings. This Work Plan
has been prepared to complete additional assessment activities to further evaluate risks
associated with redevelopment of the Site. A summary of background information and previous
assessment activities conducted is provided below.

1.1 Previous Assessment Activities
March 2021 Phase I ESA
In March 2021, H&H completed Phase I ESA activities and identified the following
environmental concerns in connection with historical operations at the Site:
The Site has been utilized for automotive repair and maintenance operations since the
early 1970s. Automotive repair operations likely used petroleum products and/or
chlorinated solvents. The Site is also listed in the environmental databases as generator of
hazardous wastes as early as 1989. There are no release incidents reported in the
environmental databases associated with hazardous wastes or historical automotive repair
and maintenance operations at the Site. However, H&H observed significant oil staining,
degraded surfaces, unlabeled 55-gallon drums and 275-gallon plastic totes of unknown
fluids, a wash bay with associated floor drains, and open waste oil pans/containers in
multiple areas in and around the Site buildings during the Site reconnaissance. Based on
the reported use of hazardous materials and observations at the time of Site
reconnaissance activities, the potential for impact from an undocumented release or
releases associated with over 40 years of on-Site auto repair operations is considered an
environmental concern.
During the Site reconnaissance, H&H observed evidence of four (4) potential
underground storage tanks (USTs) within and adjacent to Building 3 (i.e., fill ports and/or
vent piping). Aside from the UST removed in 1993 (discussed below), no other USTs are
listed for the Site in the environmental databases. The potential for impact from an
undocumented release associated with the potential USTs and the potential for additional
unidentified USTs is an environmental concern.
H&H observed approximately twenty out-of-use in-ground hydraulic lifts in the service
garage of Building 3 and one out-of-use in-ground hydraulic lift in the service garage of
Building 2. Details about the in-ground lifts (i.e., installation dates, service records,
closure records, etc.) were not available at the time of the Phase I ESA. Based on the lack
of reports documenting lift system closure, the potential for impact to the Site from an
3
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/ardent - aco/aco.002 - 6500 south
boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
undocumented release from the hydraulic lift systems represents an environmental
concern.
A trench drain and oil-water separator system was installed during construction of the
southern Site building (Building 4) in the mid- to late-1990s. At the time of Site
reconnaissance activities, standing fluids were observed within the trench drains located
in the maintenance area of the Site building. Based on the age of the trench drain and
oil/water separator (OWS) system and the observed conditions of the trench drain within
the building, the potential for impacts to the Site associated with a release from the trench
drain and OWS system is considered an environmental concern.
A Historical Recognized Environmental Condition (HREC) is generally defined as an
environmental concern which involves a past release of hazardous substances or petroleum
products that has been addressed to the satisfaction of the applicable regulatory authority and that
is not subject to activity and/or use limitations. H&H identified the following HREC in
connection with the Site:
Based upon review of available environmental reports, one 3,000-gallon motor oil UST
was removed from the Site in February 1993. After removal of the UST, three soil
samples were collected for laboratory analysis from the base of the UST basin. Two soil
samples were submitted for laboratory analysis of oil and grease by EPA Method 9071
and halogenated solvents by EPA Method 8021 and one soil sample was submitted for
metals by toxicity characteristic leachate procedure (TCLP).
Soil sample laboratory analytical results indicated that oil and grease (up to 630
milligrams per kilogram {mg/kg}) was detected at concentrations above the North
Carolina Department of Environmental Quality (DEQ) UST Section Action Level at the
time of 250 mg/kg (Incident No. 13888). Halogenated solvents and metals were not
detected in the soil samples at concentrations above the regulatory screening criteria.

boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
A Site Sensitivity Evaluation (SSE) was completed for the Site to evaluate potential risks
associated with residual oil and grease concentrations in soil in the area of the former
UST. Results of the SSE indicated that no water supply wells were identified within a
1,500 ft radius of the release incident. Based on results of the SSE, the DEQ UST Section
issued a No Further Action (NFA) letter on August 6, 1996. Based on the closed
regulatory status of the incident without implementation of land or activity use
restrictions, the release associated with the former 3,000-gallon motor oil UST represents
a HREC in connection with the Site.
2021 Phase II ESA
In August 2021, H&H performed Phase II ESA activities at the Site. Assessment activities
included the advancement of eight (8) soil borings near areas of concern (i.e., drains, former and
suspect USTs, and an OWS), three (3) background soil borings, and twenty-four (24) soil
borings adjacent to former in-ground hydraulic lifts for a total of thirty-four (34) soil samples
selected for laboratory analysis. Assessment activities also included groundwater sample
collection from five (5) temporary monitoring wells. Additionally, fifteen (15) soil gas samples
were collected within the footprint of proposed townhome buildings. Soil, groundwater, and soil
gas sample locations from the 2021 Phase II ESA are depicted in Figure 2.
Results of the soil assessment activities completed in the vicinity of the former in-ground
hydraulic lifts identified total petroleum hydrocarbons as diesel range organics (TPH-DRO)
concentrations above the DEQ UST Section Action Level at six of the twenty-four lift systems.
Hexavalent chromium was detected in samples collected near the former in-ground hydraulic
lifts, trench drains associated with the OWS system, and former wash bay floor drain above the
DEQ Inactive Hazardous Sites Branch (IHSB) Residential Preliminary Soil Remediation Goals
(PSRGs) and background concentrations. No other compounds were detected at concentrations
above the DEQ screening criteria in soil samples collected at the Site.
Results of groundwater assessment activities completed in upgradient and downgradient portions
of the Site and in areas of environmental concern did not identify compounds at concentrations
above 2L Groundwater Quality Standards or the DEQ Division of Waste Management (DWM)

boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
Vapor Intrusion Groundwater Screening Levels (GWSLs).
Results of soil gas assessment activities completed within the footprint of the proposed
townhome buildings identified several compounds at concentrations above the DEQ DWM
Residential and/or Non-Residential Vapor Intrusion Soil Gas Screening Levels (SGSLs). The
compounds ethylbenzene was detected in sample SG-7, installed adjacent to Building 3 (Figure
3), at a concentration above the DWM Non-Residential Vapor Intrusion SGSL of 490 µg/m3.
Laboratory analytical results for sample SG-7 also detected concentrations of 1,2,4-
trimethylbenzene, 1,3,5-trimethybenzene, m&p-xylene, o-xylene, n-heptane, n-hexane, and
tetrachloroethene (PCE) exceeding the DWM Residential Vapor Intrusion SGSLs. Risk
calculator results using compound concentrations detected in the soil gas samples indicate that
the worst-case calculated cumulative lifetime incremental carcinogenic risk (LICR) and hazard
index (HI) values exceed the DEQ and EPA acceptable thresholds of 1 x 10-4 and 1.0,
respectively.
1.2 Brownfields Activities
To address potential environmental concerns associated with historical on-Site and off-Site
operations, the Site was entered into the DEQ Brownfields Program and received eligibility in a
letter dated October 29, 2021. The PD elected to participate in the Brownfields Program
Redevelopment Now option. As part of this process, a kick-off/data gap meeting with PD,
environmental counsel for the PD, DEQ Brownfields personnel, and H&H was held on January
13, 2022 to discuss prior Site history, proposed redevelopment plans, previous sampling data,
and the proposed schedule for completing the Brownfields Agreement.
The purpose of the Brownfields assessment activities described herein are proposed to address
DEQ Brownfields Program requests provided in an email dated January 24, 2022 for collection
of sub-slab and exterior soil gas samples to further evaluate the potential for structural vapor
intrusion. Additional assessment activities also include the collection of one soil sample to
further assess the potential risks to Site workers and future Site occupants and to address DEQ
Brownfields Program request to evaluate the potential for impacts in the area of a previously

collected soil gas sample. A summary of the proposed Brownfields assessment activities is
provided below.

boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
2.0 Additional Brownfields Assessment Activities
The proposed assessment activities will be performed in general accordance with the DEQ
Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of
Contaminated Sites (Guidelines) dated July 2021, the DEQ Division of Waste Management
(DWM) Vapor Intrusion Guidance (VI Guidance) dated March 2018, and most recent versions
of the U.S. Environmental Protection Agency (EPA) Region IV Laboratory Services and Applied
Science Division (LSASD) Field Branches Quality System and Technical Procedures guidance.
Prior to conducting the proposed assessment field activities, H&H will contact North Carolina
811, the public utility locator, to mark subsurface utilities located on the Site. H&H will also
contract with a private utility locator to screen proposed sample locations for subgrade utilities
that may not be marked by the public locator. Additionally, boring locations will be hand cleared
to approximately 5 ft bgs prior to use of mechanical drilling equipment to further screen the
boring locations for the presence of subsurface utilities.
2.1 Soil Sampling Activities
H&H will conduct soil sampling as part of the Brownfields assessment activities. The purpose of
the soil sampling is to address DEQ Brownfields Program request to evaluate the potential for
impacts in the vicinity of Phase II ESA soil gas sample SG-7, collected along the northern
exterior wall of Building 3. The location of the proposed soil boring is shown in Figure 3. A
tabular summary of proposed soil sample depths, objectives, and laboratory analyses are
summarized in Table 1.
H&H will team with a qualified drilling contractor to advance soil borings at the Site. During
boring advancement, soil will be logged for lithological description and field screened for
indication of potential impacts by observation for obvious staining, unusual odors, and the
presence of volatile organic vapors using a calibrated photoionization detector (PID). One soil
boring (SB-9) will be advanced to approximately 10 ft bgs in the vicinity of the soil gas sample
SG-7 located north of Building 3. Based upon field observations, one soil sample will be
8
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/ardent - aco/aco.002 - 6500 south
boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
collected for laboratory analysis from the depth interval with the highest potential for impacts. If
no obvious impacts are observed during field screening, a sample will be collected from the 6-7
ft bgs depth interval. If obvious impacts are observed during field screening, H&H will advance
additional borings downgradient of SB-9 to further evaluate the lateral extent of potential
impacts.
The soil sample selected for laboratory analysis will be placed in dedicated laboratory supplied
sample containers, labeled with the sample identification, date, and requested analysis, and
placed in a laboratory supplied cooler with ice. The sample will be delivered to a North Carolina
certified laboratory under standard chain of custody protocols for laboratory analysis of volatile
organic compounds (VOCs) by EPA Method 8260, semi-VOCs (SVOCs) by EPA Method 8270,
Resource Conservation and Recovery Act (RCRA) metals by EPA Methods 6020/7471, and
hexavalent chromium by EPA Method 7199.
Following sampling activities, the soil boring will be properly abandoned and the surface will be
repaired similar to pre-drilling conditions. Additionally, the soil sample location will be
estimated using a hand-held global positioning system (GPS) unit.
2.2 Sub-Slab and Exterior Soil Gas Sampling Activities
To further evaluate the potential for structural vapor intrusion, H&H will collect six (6) sub-slab
soil gas samples (SSV-1 through SSV-6) within the existing Site buildings. The approximate
locations of the proposed sub-slab soil gas sampling points are shown on Figure 3, and are
described further below:
One (1) sub-slab soil gas sample will be collected in Building 2,
three (3) sub-slab soil gas samples will be collected in Building 3, and
two (2) sub-slab soil gas samples will be collected in Building 4.
The sub-slab soil gas sample locations shown in Figure 3 may be adjusted to 1) minimize
damage to floors or floor coverings, and 2) to analyze sub-slab conditions in areas separated by
building footers if indications of building footers are observed during field sample location
9
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/ardent - aco/aco.002 - 6500 south
boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
selection.
H&H will also install one (1) temporary exterior soil gas sampling point (SG-16) to further
evaluate the potential for structural vapor intrusion into proposed townhome buildings in areas
located northeast of Building 3. The location of the temporary exterior soil gas sampling point is
shown on Figure 3.
The sub-slab soil gas sampling points will be installed using a rotary hammer drill and 1½-inch
diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾
inches below the slab surface. A drill guide will then be placed within the pilot hole, and a 5/8-
inch diameter drill bit will be utilized to advance a boring through the concrete slab and
approximately 6-inches into the underlying soil. Following borehole advancement, loose
concrete cuttings will be removed from each boring, and a Cox-Colvin Vapor PinTM (vapor pin)
assembly (brass sampling point and silicone sleeve) will be seated in the borehole using an
installation/extraction tool and dead blow hammer to form an air tight seal.
The exterior soil gas sampling point will be installed to a depth approximately 5 ft above the
water table and no shallower than 5 ft bgs. Based on previous assessment activities completed at
the Site, the temporary exterior soil gas sampling point will be installed to a depth of
approximately 5.5 ft bgs. The soil gas sampling point boring will be advanced using a
decontaminated stainless-steel decontaminated hand auger to approximately 5 ft bgs and a DPT
capable drill-rig to depth. An approximate 6-inch stainless steel vapor implant screen attached to
Teflon® sample tubing will then be placed at the base of the borehole. Annular space around the
vapor implant screen will be filled with filter sand to a depth of approximately 6-inches above
the vapor screen. Following installation of the sand, hydrated bentonite will be installed in the
boring from the top of the sand to near the ground surface. The soil gas sampling point will be
allowed to equilibrate after installation and prior to sample collection.
The sub-slab and exterior soil gas samples will be collected utilizing a laboratory supplied batch
certified stainless-steel Summa® canister (1-liter or 3-liter canisters depending on laboratory
availability) connected to an air-flow regulator calibrated by the laboratory to collect the soil gas
sample at a rate of approximately 100 milliliters per minute. Prior to sample collection, a “shut-
10
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/ardent - aco/aco.002 - 6500 south
boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
in” test will be conducted on the sampling train and helium leak checks will be conducted at each
sampling point. The purpose of the shut-in test and helium leak check is to ensure short
circuiting with ambient air does not occur during sampling. A description of the shut-in test and
helium leak testing procedures is provided below.
The shut-in test will be conducted by connecting the flow regulator with the vacuum gauge to the
Summa® canister and sealing the flow regulator with the laboratory provided brass cap. Once the
sampling train is “closed”, the sample valve on the Summa® canister will be opened and the
reading on the vacuum gauge will be recorded. The Summa® canister sample valve will then be
closed and the vacuum gauge will be observed to ensure no vacuum loss occurs. If the vacuum
reading remains the same, the shut-in test will be considered successful. If vacuum loss occurs,
the flow regulator and/or brass cap will be reseated and the shut-in test will be repeated until the
vacuum reading remains stable.
Following the shut-in test, the Summa® canister will be connected to the sample point via
Teflon® sample tubing using a brass nut and ferrule assembly to create an air tight seal and the
leak check will be performed. The leak check will be performed by constructing a shroud over
the sample train at each sampling point and flooding the air with helium gas. Helium
concentrations inside the shroud will be measured using a calibrated helium gas detector and
maintained at concentrations of approximately 15% to 30% for the duration of the leak check.
Once helium concentrations stabilize within the shroud, the sample tubing will be purged outside
of the shroud using a syringe and a three-way valve to collect purged soil gas into a Tedlar® bag.
The purged soil gas will then be analyzed using the helium gas detector to ensure that helium
concentrations in the sampling train are less than 10% of the helium concentrations measure
within the shroud.
Following a successful leak check, the intake valve on the Summa® canister will be fully opened
to begin collection of the soil gas sample. Vacuum readings on the Summa® canister will be
recorded prior to and following the sampling period to ensure adequate sample volume was
collected. A vacuum of approximately 5 inches of mercury or more will be maintained within the
canisters at the conclusion of the sampling event in accordance with DEQ DWM guidance.

boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
Following sample collection, the Summa® canisters will be placed in laboratory supplied shipping
containers, properly labeled, and shipped under standard chain-of-custody protocols to a qualified
laboratory for analysis of VOCs by EPA Method TO-15. The laboratory will be requested to use
reporting limits that are below DEQ DWM Residential Vapor Intrusion SGSLs.
After sample collection, the sample locations will be estimated by measuring from known
benchmarks within the building (e.g., doors, windows, exterior walls, etc.) or with a hand-held
GPS.
2.3 Quality Assurance – Quality Control
Non-dedicated equipment and tools will be decontaminated prior to use at each boring or
sampling location or following exposure to soil or groundwater. The following samples will be
collected for quality assurance/quality control (QA/QC) purposes:
One duplicate soil sample will be collected and analyzed for the same parameters as the
parent sample.
One duplicate sub-slab soil gas sample will be collected using a laboratory supplied
“t-fitting” which allows for two soil gas samples to be collected from one soil gas
monitoring point simultaneously. The duplicate soil gas sample will be submitted for
analysis of VOCs by EPA Method TO-15.
Laboratory QA/QC procedures will be employed to ensure appropriate sample handling and
analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be
conducted in accordance with the method protocols and will include regular equipment
maintenance, equipment calibrations, and adherence to specific sample custody and data
management procedures. Samples will be analyzed in conjunction with appropriate blanks,
laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking
standards in accordance with approved methodologies to monitor both instrument and analyst
performance. Laboratory reporting limits for each analyte will be at or below appropriate
12
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/ardent - aco/aco.002 - 6500 south
boulevard/brownfields/assessment/work plan/25046 - harrelson ford_brownfields assessment work plan.doc
screening criteria, where possible. Additionally, H&H will request that the laboratory include
estimated concentrations for compounds that are detected at levels above the laboratory method
detection limit, but below the laboratory reporting limit (J flags).
The laboratory analytical data report and QA package submitted to and analyzed by the
subcontracted laboratory will be provided in an appendix to the final report. Laboratory QA data
consistent with Level II documentation will be provided for this project. A copy of the completed
chain of custody record and shipping receipt will be appended to the corresponding laboratory
analytical report included with the final report.
2.4 Investigation Derived Waste (IDW) Management
Investigation derived waste (IDW) generated during the proposed assessment activities is
expected to be minimal and will be placed back in the holes or thin spread on-Site. However, if
significant impacts are suspected (i.e., free-product) the soil cuttings will be containerized in
labeled 55-gallon drums and staged on-Site pending analytical results of a composite IDW
sample. Based on laboratory analytical results of IDW samples, the drums will be transported
off-Site to a suitable facility.
2.5 Reporting
Following completion of the assessment activities and receipt of the analytical data, H&H will
document our findings in a Brownfields Assessment Report. The report will include a description
of Site activities, rationale for potential deviations from the work plan (if warranted), a figure
depicting sample locations, tabular summaries of the data, laboratory analytical data, a
discussion of the data in comparison to regulatory screening levels, cumulative risk calculations
for sub-slab and exterior soil gas analysis (if warranted based upon the data), and conclusions
and recommendations concerning our activities.
