1.0 INTRODUCTION
This Supplemental Soil Excavation Completion Report presents methods and results of the
supplemental soil over excavation and post-excavation soil gas sampling activities completed
in December 2023 and January 2024 at the Harrelson Ford Brownfields Property located at
6500 South Boulevard in Charlotte, Mecklenburg County, North Carolina (the site). The site
is undergoing redevelopment under the North Carolina Department of Environmental
Quality (NCDEQ) Brownfields Redevelopment Section (BRS) (Brownfields Project No. 25046-
21-060). Current redevelopment plans for the site include construction of 165 residential
townhomes and associated amenities.
A Notice of Brownfields Property was filed on October 13, 2023, that included a Brownfields
Agreement for the site. Land Use Restriction 12.b.(i) generally indicates that soil impacted
with chlorinated solvent compounds at concentrations above NCDEQ Protection of
Groundwater Preliminary Soil Remediation Goals (PSRGs) as identified in the Soil Excavation
Completion Report prepared by Hart & Hickman, P.C., dated March 30, 2023, must be
excavated prior to construction of townhomes at the site. Land Use Restriction 12.b.(ii)
requires confirmation soil gas sampling at the areas of excavation with analytical results
meeting residential risk criteria and with no trichloroethylene (TCE) detected above the
Residential NCDEQ Vapor Intrusion Screening Level or other suitable level approved in
advance of construction by NCDEQ. In a letter from the NCDEQ BRS dated August 25, 2023,
(Re: Redevelopment Status) approval was given to proceed with townhome redevelopment
in portions of the site not located within the areas of excavation.
Previous soil excavation activities performed at the site were summarized in the Soil
Excavation Completion Report (Completion Report) prepared by Hart & Hickman, P.C., dated
March 30, 2023, and included removal of impacted soil from accessible areas of concern
beneath two site buildings. Additional details of the previous excavation activities are
discussed further in Section 1.2. A Soil Excavation and Post-Excavation Sampling Work Plan
(Work Plan) was prepared by Hart & Hickman, P.C., dated October 6, 2023, presenting

procedures to remove limited volumes of soil that could not be removed below structural
components within buildings during previous excavation activities, and to collect post-
excavation soil gas samples to meet the requirements of Land Use Restrictions 12.b.(i) and
12.b.(ii). The Work Plan was approved by NCDEQ on October 9, 2023. Soil over excavation
and post-excavation sampling activities were completed by Hanley Environmental, or under
their supervision, on behalf of the current property owner, Tri Pointe Homes Holdings, Inc.,
and this report presents documentation of site activities, results, conclusions, and
recommendations.
1.1 Site Description and Redevelopment Activities
The site consists of one parcel (Parcel ID 17304204) with a total area of approximately 10.58
acres. A map depicting the site vicinity is included as Figure 1, and a site map is provided as
Figure 2. Tri Pointe Homes Holdings, Inc. acquired the property on October 16, 2023.
Demolition of site buildings was completed in October and November 2023, and site
work/mass grading associated with the planned townhome redevelopment is ongoing
pursuant to the Environmental Management Plan (EMP) dated October 20, 2023.
1.2 Previous Soil Excavation Activities
Previous soil excavation activities at the site, which were performed on behalf of a prior
owner, are summarized in the Soil Excavation Completion Report (Completion Report) dated
March 30, 2023. Data summary excerpts from the Completion Report are included in
Appendix A. Previous excavation activities were performed in accordance with the Soil
Excavation Work Plan prepared by Hart & Hickman, P.C., dated November 22, 2022, and an
EMP dated November 4, 2022.
Previous soil excavation activities were conducted from January 2023 through March 2023
as a strategy to remove soil impacted with chlorinated solvents beneath two former building
slabs. Soil excavation was performed in five areas of concern and resulted in approximately
1,736 tons of impacted soil removed and disposed of at the Republic Services Municipal Solid
Waste landfill in Concord, North Carolina. The results of post-excavation confirmation soil

sample analyses indicated that chlorinated solvent-impacted soil beneath former auto
service areas within the former Building 3 and Building 4 had been removed to unrestricted
use levels for protection of human health. Trace levels of PCE and TCE were present in several
discrete areas near load-bearing walls of Building 3 and Building 4 in soil that could not be
easily excavated while maintaining structural integrity of the buildings.
2.0 SOIL EXCAVATION ACTIVITIES
Pursuant to the Work Plan, residual contaminated soil beneath Building 3 and Building 4 was
excavated following demolition of the buildings. The following sections provide information
on excavation procedures, confirmation soil sampling procedures, sampling locations, and
results. A map depicting excavation areas and soil sample locations is included as Figure 3.
Procedures for excavation and sample collection generally followed the procedures
described in the Work Plan.
2.1 Excavation Procedures
On December 13, 2023, Hanley Environmental provided oversight of soil excavation activities
completed by Paragon Site Solutions, LLC of Charlotte, North Carolina (Paragon). Over
excavation areas were surveyed and staked in advance by Paragon using coordinates
obtained from CAD files of the excavation areas provided by Hart & Hickman, PC. Over
excavation was completed at the five over excavation areas depicted on Figure 3. Excavated
soil was field screened using a calibrated photoionization detector (PID). The excavation
areas initially extended horizontally to the surveyed boundaries, and were expanded further
if necessary until field screening results indicated a low likelihood of impacts. Excavation
depths ranged from approximately 9.0 feet below ground surface (ft bgs) to 10.6 ft bgs. The
approximate depth to the groundwater capillary fringe in this portion of the site was
reported in the Work Plan to be 9 ft bgs. The over excavation areas extended to the
approximate depth of the water table capillary fringe, but did not extend into the water table,
and groundwater was not encountered in excavations.

The final extents of over excavation areas are shown on Figure 3 and final excavation
dimensions are summarized in the table below.
Over Excavation Area Length (ft) Width (ft) Depth (ft)
B 12.3 11.2 10.6
D 7.5 13.2 9.7
E1 7.3 10.2 9.5
E2 10.7 6.7 9.0
E3 13 8.2 9.0
Approximately 192 cubic yards (CY) of soil was direct-loaded into trucks and transported to
the Republic Services Municipal Solid Waste Landfill located in Concord, North Carolina for
disposal. Soil disposal documentation provided by Paragon is included in Appendix B.
2.2 Confirmation Soil Sampling Procedures
Following soil excavation, soil sample aliquots from each excavation sidewall were collected
directly from the excavator bucket, taking care not to sample soil in contact with the bucket.
In accordance with the Work Plan, samples were not collected from the excavation bases
because excavation depths were not shallower than 9 ft. One soil sample aliquot was
collected at a frequency of every 10 linear feet from each excavation sidewall from the 0-3 ft
bgs, 3-6 ft bgs, and 6-9 ft bgs depth intervals and field screened using a calibrated PID. The
aliquot with the highest potential for impact based on field screening from each sidewall was
selected for laboratory analysis. If soil sample aliquot PID responses did not indicate likely
impacts, the 3-6 ft bgs depth interval was selected for laboratory analysis. A summary of
confirmation PID response measurements is included in Table 1.
The final excavation extents resulted in a total of 21 confirmation soil samples collected for
laboratory analysis. The locations of the confirmation soil samples are shown in Figure 3.
For quality assurance/quality control (QA/QC) purposes, one duplicate soil sample was
Supplemental Soil Excavation Completion Report
Harrelson Ford Brownfields Property

collected from the OEX-E3(C)-2 confirmation soil sample location. Soil samples were labeled
with sample identification, date, and requested analysis, and placed in a cooler with ice. The
samples were delivered to Waypoint Analytical, Inc. (Waypoint) of Charlotte, North Carolina,
a North Carolina certified laboratory, under standard chain of custody protocol for analysis
of PCE and TCE by EPA Method 8260.
Confirmation soil sample locations were recorded using a hand-held global positioning
system (GPS) unit. Following sample collection, the excavation basins were backfilled with
compacted clean fill material imported from Vulcan Materials Company located at 10526 Old
Nations Ford Road in Charlotte, North Carolina and/or cut soil from other parts of the site.
2.3 Confirmation Soil Sampling Results
Confirmation soil sample analytical results were compared to the NCDEQ Protection of
Groundwater PSRGs dated February 2024 and are summarized in Table 2. The laboratory
analytical report and chain-of-custody record is included in Appendix C.
Laboratory results indicate the presence of PCE in confirmation soil sample OEX-E2(C) (3-6 ft
bgs) at an estimated “J-flag” value of 0.003 J milligrams per kilogram (mg/kg), which is below
the Protection of Groundwater PSRG for PCE of 0.0063 mg/kg. Neither PCE nor TCE were
detected in the other confirmation soil samples at a concentration above the laboratory
method detection limits. The results of confirmation soil sampling demonstrated that PCE
and TCE were not present at concentrations above the Protection of Groundwater PSRG and
the requirements of Land Use Restriction 12.b.(i) related to townhome redevelopment have
been satisfied.
3.0 SOIL GAS SAMPLING ACTIVITIES
The following sections provide information on post-excavation soil gas sampling procedures
and results. A map depicting the soil gas sample locations is included as Figure 4. These
activities generally followed the procedures described in the Work Plan.

3.1 Soil Gas Sampling Procedures
On January 10, 2023, approximately one month following the over excavation activities,
eleven temporary soil gas probes were installed and subsequently sampled (BF-SG-1 through
BF-SG-11) by Hanley Environmental. Five soil gas probes (BF-SG-1 through BF-SG-5) were
installed within the footprints of Excavation A through Excavation D (beneath former Building
3), four soil gas probes were installed in the footprint of Excavation E (beneath former
Building 4), one soil gas probe (BF-SG-10) was installed south of Excavation D, and one soil
gas probe was installed east of Excavation E (BF-SG-11).
Pursuant to the Work Plan, the soil gas samples were collected from approximately five ft
bgs. The temporary soil gas sampling probes were installed using a decontaminated
stainless-steel hand auger. Soil gas probes consisted of a 6-inch length screened soil gas
sampling implant connected to ¼-inch diameter Teflon® tubing which extended to the
ground surface for sample collection. A sand filter-pack was placed around the sampling
implants to a height of approximately six inches above the screen (top of sand filter-pack
was at four ft bgs). Hydrated granular bentonite was placed above the screen to the ground
surface. The soil gas probes were allowed an equilibration period of 24 hours prior to sample
collection. Boring logs and soil gas probe construction diagrams are included as Appendix
D.
Summa® canisters with 1.4-liter volume individually certified by the laboratory were used to
collect the soil gas samples. Canisters were inspected prior to sampling to verify that vacuum
levels were within 10% of the level recorded by the laboratory prior to shipment. Vacuum
shut-in testing was performed at each sample location by closing a valve on the sample train
to prevent airflow from the probe tubing to the sample train. The valve on the Summa®
canister was then opened to confirm no vacuum losses occurred in the sample train.
At least three sample train volumes of air were purged from each sample point prior to
sampling. During purging, the sample canister, tubing, and sample point were surrounded
with a shroud consisting of a plastic container. The container was filled with helium to
Supplemental Soil Excavation Completion Report
Harrelson Ford Brownfields Property

concentrations ranging from 9.1% to 12.2% as measured using a Dielectric MGD 2002 helium
detector. Purged vapors were collected in Tedlar® bags using a GilAir5 air sampling pump.
The helium concentration of the vapor in the Tedlar® bags was measured. If the
concentration of helium in extracted vapors was greater than 10% of the helium
concentration in the shroud, the sample train connections and sampling point seal were
reevaluated and improved, and additional helium testing was performed until an acceptable
result of less than 10% of the shroud helium concentration was measured.
Following successful purging and leak testing, a soil gas sample was collected into the sample
canister at a flow rate of approximately 140 milliliters per minute (mL/min). For QA/QC
purposes, one duplicate sample (BF-SG-DUP) was collected from the BF-SG-1 location using
a laboratory-supplied “T” fitting which allows for simultaneous collection of two samples
from a single sample location. Final vacuum levels ranged from 4 to 5 inches of mercury (in
Hg) vacuum in the canisters. Field sampling forms are included as Appendix E. After
sampling, the canisters were transported under chain-of-custody protocols to Waypoint for
analysis of volatile organic compounds (VOCs) by EPA Method TO-15 using the laboratory’s
standard analyte list.
Soil gas sample locations were recorded using a handheld GPS. After sample collection, the
soil gas sampling probes were abandoned by Hanley Environmental. Soil cuttings generated
during boring advancement were thin-spread on site.
3.2 Soil Gas Sampling Results
Soil gas analytical results were compared to the NCDEQ Residential Sub-Slab and Exterior
Soil Gas Screening Levels (SGSLs), based on the target cancer risk (TCR) of 1x10-6 and target
hazard quotient (THQ) of 0.2, dated February 2024, and are summarized in Table 3. The
laboratory analytical report and chain-of-custody record are included in Appendix C.
Soil gas results indicate the presence of several VOCs at concentrations above laboratory
reporting limits in each of the soil gas samples collected. TCE was detected at concentrations

exceeding the Residential SGSL of 14 micrograms per cubic meter (µg/m3) in two soil gas
sample locations; BF-SG-1/BF-SG-DUP at concentrations up to 117 µg/m3, and BF-SG-9 at a
concentration of 44.4 µg/m3. Several other compounds were detected at concentrations
exceeding the Residential SGSLs including benzene (BF-SG-1/BF-SG-DUP through BF-SG-6,
BF-SG-8, BF-SG-10, and BF-SG-11), bromodichloromethane (BF-SG-2), chloroform (BF-SG-2,
BF-SG-4, and BF-SG-5), ethylbenzene (BF-SG-1 through BF-SG-6, BF-SG-8, BF-SG-10, and BF-
SG-11), and naphthalene (BF-SG-1/BF-SG-DUP). No compounds were detected at
concentrations above Non-Residential SGSLs.
Figure 4 displays the locations of excavation areas and soil gas samples on a site plan with
proposed building locations. The two locations with TCE concentrations exceeding the
Residential SGSL (BF-SG-1 and BF-SG-9) are outside of proposed building footprints. Several
sample locations are beneath proposed buildings (BF-SG-2 and BF-SG-5 beneath proposed
Building 13 and BF-SG-8 beneath proposed Building 17), where TCE was not present in soil
gas at concentrations above the Residential SGSL.
Considering the density of soil gas samples collected and the isolated occurrence of TCE at
concentrations exceeding its Residential SGSL at two of the eleven sample locations, the
results of soil gas sampling are not indicative of a significant remaining source of chlorinated
solvents in soil. The soil gas to indoor air pathway for the constituent concentrations
detected can be reliably mitigated by installing and maintaining vapor intrusion mitigation
systems on planned site buildings.
3.3 Risk Calculations
To further evaluate the post-excavation soil gas data, Hanley Environmental utilized the
NCDEQ Risk Calculator (February 2024 version) to calculate potential cumulative risks using
concentrations of VOCs detected in the soil gas samples. The results of risk calculations are
summarized in Table 3 and risk calculator outputs are provided in Appendix F.
Supplemental Soil Excavation Completion Report
Harrelson Ford Brownfields Property
9

Risk calculations were completed for each sample individually, and also using the highest
detected concentration of each compound across all samples to represent a conservative,
“worst case” risk for the post-excavation areas. As shown in Table 3, the calculated lifetime
incremental cancer risk (LICR) did not exceed 10-4 in post-excavation soil gas samples, and
the hazard index (HI) exceeded 1 in one sample (BF-SG-1/SG-DUP). The conservative, “worst-
case” risk calculator results indicated a LICR of 3.2 x 10-5 and a HI of 2.2, however, a
comparison of SG-1 risk calculator results indicates “worst-case” risk calculator results were
predominantly influenced by soil gas sample BF-SG-1.
The sample location with a hazard index exceeding 1 (BF-SG-1) was outside of proposed
building footprints (see Figure 4). Sample locations beneath proposed buildings (BF-SG-2
and BF-SG-5 beneath proposed Building 13 and BF-SG-8 beneath proposed Building 17), had
a LICR and HI below target values.
4.0 QUALITY ASSURANCE/QUALITY CONTROL
For QA/QC purposes, one duplicate soil sample was collected from the OEX-E3(C)-2
confirmation soil sample location and one duplicate soil gas sample was collected from the
BF-SG-1 location. A Level II QA/QC data package was included in the laboratory analytical
reports. After a review of the QA/QC data in each laboratory report, the qualifiers listed in
the laboratory reports are not considered to raise data quality concerns about the usability
of data. Furthermore, comparison of the duplicate sample results to the parent samples
indicated similar results.
5.0 CONCLUSIONS AND RECOMMENDATIONS
Soil over excavation and post-excavation soil gas sampling activities were performed at the
Harrelson Ford Brownfields Property in December 2023 and January 2024. Field activities
were conducted pursuant to the Work Plan dated October 6, 2023. A summary of results and
discussion of findings related to soil gas assessment results, risk to future occupants, and
Land Use Restriction 12.b is presented below.

Soil
 Approximately 192 CY of soil was excavated and disposed at a Subtitle D landfill.
Excavations extended to the approximate depth of the water table capillary fringe.
 The results of confirmation soil sampling demonstrated that PCE and TCE were not
present at concentrations above the Protection of Groundwater PSRG.
 The results of confirmation soil sampling demonstrate that the requirements of Land
Use Restriction 12.b.(i) related to townhome redevelopment have been satisfied, and
that no significant soil source of chlorinated solvents remains at the site following the
remedial soil excavations.
Soil Gas/Vapor Intrusion Potential
 TCE was detected at concentrations above the Residential SGSL at two soil gas sample
locations, BF-SG-1 and BF-SG-9. Benzene, bromodichloromethane, chloroform,
ethylbenzene, and naphthalene were also detected at concentrations exceeding
Residential SGSLs in one or more samples.
 The two soil gas sample locations with TCE concentrations exceeding the Residential
SGSL (BF-SG-1 and BF-SG-9) are outside of proposed building footprints. Several
sample locations are beneath proposed buildings (BF-SG-2 and BF-SG-5 beneath
proposed Building 13 and BF-SG-8 beneath proposed Building 17), where TCE was not
present in soil gas at concentrations above the Residential SGSL.
 The calculated LICR did not exceed 10-4 in post-excavation soil gas samples, and the
HI exceeded 1 in one sample (BF-SG-1/SG-DUP).
 As a conservative measure, the worst-case vapor intrusion risk was calculated using
the maximum concentrations detected across all post-excavation soil gas samples.
The risk calculator results indicated a LICR of 3.2 x 10-5 and a HI of 2.2, however, a
comparison of SG-1 risk calculator results indicates “worst-case” risk calculator results
were predominantly influenced by soil gas sample BF-SG-1.
Supplemental Soil Excavation Completion Report
Harrelson Ford Brownfields Property

 The sample location with a hazard index exceeding 1 (BF-SG-1) was outside of
proposed building footprints. Sample locations beneath proposed buildings (BF-SG-2
and BF-SG-5 beneath proposed Building 13 and BF-SG-8 beneath proposed Building
17), had a LICR and HI at levels meeting the standard set forth in LUR 12b.(ii).
Vapor intrusion mitigation systems, which will be installed on all townhomes at the site, can
reliably mitigate the soil gas to indoor air pathway for the constituent concentrations
detected. In recognition of the isolated detections near Building 13 and Building 17
exceeding the thresholds set forth in LUR 12.b.(ii), active mitigation systems will be installed
on those buildings as an additional measure to mitigate risk to occupants. Furthermore,
trench dams will be installed at all site buildings along buried utilities at the locations where
the utilities pass beneath site buildings to prevent soil gas transport underneath the
buildings.
Land Use Restriction 12.b.(ii) allows for approval of alternative suitable levels of confirmation
soil gas results by NCDEQ in advance of townhome construction. Considering the extent and
completeness of soil remediation conducted, the isolated occurrence of TCE detections
exceeding the thresholds set forth in LUR 12.b.(ii), the locations of those TCE detections
(outside of proposed building footprints), and the conservative mitigation measures that are
proposed to be used in nearby buildings, the risk of vapor intrusion to proposed townhomes
in the vicinity of the excavations is low. NCDEQ’s approval of townhome construction in areas
of soil excavation is requested in accordance with LUR 12.b.(ii).

Dear Nick Hotzelt:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/13/2023 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely,
Danyale Love Project Manager

Dear Nick Hotzelt:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 1/11/2024 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love Project Manager
