1.0 Introduction

On behalf of the Prospective Developer (PD), CC Rapid Commerce Park Owner, LLC, Hart &
Hickman, PC (H&H) is pleased to present this Brownfields Assessment Work Plan (Work Plan)
to conduct Brownfields assessment activities on the undeveloped, residential, and commercial
properties located at 438-614 Rhyne Road in Charlotte, Mecklenburg County, North Carolina
(Site). A Site location map is provided as Figure 1.

The Site consists of nine contiguous parcels of land (Parcel Identification Numbers 05325114,
05325113, 05301145, 05301137, 05301133, 05301134, 05301135, 05301136, and 05301131)
that total approximately 39.25 acres. The parcels are developed with five single-family
residences with multiple outbuildings located in the northern, central, and eastern portions of the
Site and an approximately 3,900-quare foot (sq ft) vacant commercial building in the eastern
portion of the Site. The western and southern portions of the Site are comprised of undeveloped
land and an unnamed tributary of Long Creek. The Site and surrounding area are depicted on
Figure 2.

On June 8 and June 9, 2022, H&H performed a Phase II Environmental Site Assessment (ESA)
which included soil, groundwater, surface water, sediment, and soil gas sampling activities to assess
the potential for impacts at the Site related to the former on-Site and off-Site operations. A
summary of the Phase II ESA activities and analytical data is provided as follows:

 Soil samples were collected in areas of likely soil disturbance during future
redevelopment activities at the Site and near former on-Site underground storage tanks
(USTs). No volatile organic compounds (VOCs) or semi-VOCs (SVOCs) were detected
above the North Carolina Department of Environmental Quality (DEQ) Residential

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/crescent communities (cre)/cre-002
rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
and/or Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) in the soil
samples collected at the Site. Although arsenic and hexavalent chromium were detected
at concentrations above the Residential PSRGs, the concentrations were below the
Industrial/Commercial PSRGs and were generally consistent with Site-specific
background levels, background concentrations at the Brownfields property to the
northwest of the Site, and/or published background ranges for North Carolina soils
(arsenic only). Therefore, the arsenic and hexavalent chromium concentrations are
considered to be representative of naturally occurring conditions in Site soil.
Concentrations of additional metals detected in soil samples are below PSRGs and
consistent with background levels.

 Results of groundwater assessment activities indicated that no VOCs or SVOCs were
detected at concentrations above the North Carolina 2L Groundwater Standards (2L
Standards). Total chromium was identified in samples TMW-1 and TMW-3 at
concentrations slightly above the 2L Standard of 10 µg/L. However, a field-filtered
groundwater sample was collected from TMW-1 due to elevated turbidity at the time of
sampling, and results of the field-filtered sample indicated total chromium concentrations
well below the 2L Standard. Therefore, the slightly elevated total chromium
concentrations appear to be attributable to sediment within the water column and
naturally occurring conditions. Furthermore, based on depth to water measurements
[approximately 16 to 23 ft below ground surface (bgs)] and redevelopment plans, the
potential for encountering impacted groundwater during redevelopment activities appears
to be low.

 One co-located surface water and sediment sample were collected from a southeast to
northwest trending unnamed tributary of Long Creek located in the southwestern portion
of the Site. No VOCs or SVOCs were detected in the surface water sample. Metals
concentrations were below the North Carolina 2B Surface Water Standards.

Sediment analytical results indicated that no VOCs or SVOCs were detected at
concentrations above the DEQ PSRGs. Low-level metals concentrations appear to be
generally consistent with published and Site-specific background levels.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
 Soil gas and sub-slab vapor assessment activities were completed within the footprint of
the proposed industrial warehouse building and the existing commercial building to
evaluate the potential for structural vapor intrusion. Results of vapor intrusion
assessment activities indicated that the presence of acrolein, benzene, chloroform, and
ethylene dibromide (EDB) in one or more samples at concentrations above the
Residential SGSLs. Acrolein was also detected in sample SG-1 through SG-3 at
concentrations above the Non-Residential SGSL.

According to the article Problematic Compounds in Vapor Intrusion Investigations by
Bart Eklund, acrolein is often detected in samples with polar compounds, such as acetone
and methyl ethyl ketone, both of which were detected in soil gas and sub-slab vapor
samples collected from the Site. The article indicates that acrolein detections should be
considered as a false positive when reported in conjunction with polar compounds.

For the soil gas to indoor air pathway, the “worst-case” cumulative carcinogenic and non-
carcinogenic risks at the Site for a non-residential worker were calculated to be below
DEQ acceptable risk levels. Under an unlikely residential use scenario, the cumulative
carcinogenic risk for a resident was calculated to be below the DEQ acceptable risk level.
The cumulative non-carcinogenic risk including acrolein exceeded the DEQ acceptable
risk level but was below the acceptable risk level with acrolein excluded. Based on
evaluation of the risk calculator results, vapor intrusion does not appear to be a
significant concern at the Site.

The Site received a letter of eligibility for entry into the DEQ Brownfields Program (Brownfields
Project No. 26016-22-060) on November 9, 2022.

Proposed redevelopment at the Site includes demolition of the existing buildings and
construction of an approximately 448,000-sq ft industrial warehouse building, parking/truck
loading areas, and stormwater detention basins. The building will be situated on a slab-on-grade
foundation.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
On February 2, 2022, a Brownfields kick-off meeting with the H&H, PD, the PD’s
environmental counsel, and DEQ to discuss redevelopment plans, prior environmental
assessment at the Site, the timeline for redevelopment and completion of the Brownfields
process, and data gaps. Following the meeting, DEQ requested the collection of additional soil
gas samples within the footprint of the proposed warehouse building, re-sampling SB-2 and SB-3
locations to evaluate potential hazardous levels of chromium in soil, collection of groundwater
samples from two on-Site water supply wells to evaluate potential per- and polyfluorinated alkyl
substance (PFAS) impacts, and collection of soil samples in proposed cut areas. In addition,
based on the cut/fill analysis that was provided by the PD and is include as Appendix A, there is
potential for groundwater to be encountered during grading in the southern, central, and western
portions of the Site. Therefore, additional groundwater assessment is warranted to evaluate the
depth to groundwater and groundwater quality in areas of proposed deep excavation. The
proposed scope of work for soil, soil gas, and groundwater sampling, including quality
assurance/quality control (QA/QC), management of investigation derived waste (IDW), and
reporting at the Brownfields property is provided below.

2.0 Scope of Work

As noted above, the purpose of the Brownfields assessment activities described herein are
proposed to address the DEQ Brownfields Program requests to perform a receptor survey,
conduct soil sampling to evaluate potentially hazardous levels of chromium and soil conditions
in proposed cut areas, evaluate potential PFAS impacts to on-Site water supply wells, and
perform supplemental exterior soil gas sampling in the area of the proposed industrial building.
In addition, the PD has elected to perform groundwater sampling to evaluate groundwater
conditions in proposed areas of deep excavation. A tabular summary of proposed sample depths,
objectives, and laboratory analyses are summarized in Table 1. Proposed assessment activities
are briefly summarized below.

Receptor Survey
H&H will perform a Brownfields receptor survey in accordance with DEQ Brownfields Section
guidance. The receptor survey will include information about land use and zoning in the Site
area. In addition, H&H will conduct a field search for water supply wells, basements, utility
manways and chases, storm sewers, other underground utilities, drains, and surface water within
a 1,500 ft radius of the Site. In addition, H&H will review the Mecklenburg County Well
Information System to identify registered water supply wells in the area and, if warranted,
contact the utility companies for information concerning underground utilities in the immediate
area of the Site. The receptor survey will be completed using the most current version of the
Brownfields Property Receptor Survey form.

Soil Sampling Activities
Based on prior analytical data, potentially hazardous levels of chromium are present in soil at the
location of prior samples SB-2 (6-7 ft) and SB-3 (7-9 ft) based on the “Rule of 20”. Therefore,
these locations will be re-sampled for the presence of total chromium by the Toxicity
Characteristic Leaching Procedure (TCLP).

In addition, three soil samples (SB-4 through SB-6) will be collected from temporary well
borings that will be advanced in proposed cut areas in the southern, central, and western portions
of the Site.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
Soil Gas Sampling Activities
Ten temporary soil gas monitoring points (SG-6 through SG-15) will be installed at the Site and
sampled for VOCs (including naphthalene) by EPA Method TO-15. The soil gas points will be
installed across the Site within or adjacent to the footprint of the proposed warehouse building to
further evaluate vapor intrusion risk.

Groundwater Sampling Activities
To evaluate water levels and the presence of VOCs, SVOCs, and Resource Conservation and
Recovery Act (RCRA) metals in groundwater, three temporary monitoring wells (TMW-5
through TMW-7) will be installed in the southern, central, and western portion of the Site where
groundwater could be encountered during grading/excavation activities. Groundwater analytical
data will be used for evaluation of groundwater management protocol, including potential
discharge to the storm sewer, during potential de-watering activities. In addition, groundwater
samples will be collected from water supply wells in the northern portion of the Site (WSW-1)
and in the central portion of the Site (WSW-2).

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
3.0 Sampling Methodology

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, Brownfields Program
Environmental Site Assessment Work Plan Checklist dated March 2023, and the 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, all borings will be advanced to at
least 5 feet below ground surface (ft bgs) using a hand auger to further screen the boring
locations for the presence of subsurface utilities.

3.1 Soil Sampling Activities

H&H will advance two soil borings in the locations of previous borings SB-2 and SB-3 in the
eastern portion of the Site. The soil borings will be advanced to depths of approximately 7 ft bgs
and 9 ft bgs, respectively, using a decontaminated stainless-steel hand auger and direct push
technology (DPT) drill rig. In addition, three temporary well borings (SB-4/TMW-5 through
SB-6/TMW-7) will be advanced using DPT methods in areas of proposed cut in the southern,
central, and western portions of the Site. During boring advancement, continuous soil samples
will be collected from the center of the hand auger bucket and macrocore sampler and described
for lithologic purposes, observed for the presence of staining and odors, and field screened for
elevated volatile organic vapors using a calibrated photoionization detector (PID). Soil samples
will be collected from SB-1 and SB-2 at depth intervals of approximately 6-7 ft bgs and 7-9 ft
bgs, respectively, unless field screening indicates obvious soil impacts at other depth intervals.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
Soil samples will be collected from SB-4 through SB-6 unless field screening indicates obvious
soil impacts at other depth intervals.

The soil samples will be collected directly into laboratory supplied glassware, labeled with the
sample identification, time, and requested analysis, and placed on ice in a laboratory-supplied
cooler. The samples will be delivered to a North Carolina-certified laboratory under standard
chain of custody protocols.

The soil sample locations will be estimated using a hand-held GPS unit. The soil borings will be
properly abandoned using hydrated bentonite, and the ground surface will be restored to
approximately match pre-drilling conditions.

3.2 Soil Gas Sampling Activities

To evaluate the potential for structural vapor intrusion, H&H will collect 10 soil gas samples
from approximate locations discussed previously in Section 2.0 and as depicted on Figure 2.
Also, a tabular summary of proposed soil gas sampling points is presented in Table 1. Sampling
activities are described below.

Soil Gas Monitoring Point Installation
Ten temporary soil gas monitoring points SG-6 through SG-15 will be installed within or
adjacent to the footprint of the proposed warehouse building (see Figure 2). The soil gas
monitoring points will be installed at a depth of approximately 5.5 ft bgs and above the estimated
depth to the capillary fringe. The soil gas point borings will be advanced utilizing a hand-auger
to install an approximate 6-inch stainless steel vapor screen attached to Teflon® tubing that
extends to the ground surface. Following advancement, the annular space around the vapor
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 points will be purged a minimum of three
well volumes and then allowed to equilibrate for at least 24 hours following installation and
before sampling.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
Soil Gas Sampling
The 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 to 200 milliliters per minute. Prior to sample collection, a “shut-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 stainless steel or brass nut and ferrule assembly to create an
airtight seal and the leak check will be performed. The leak check will be performed by
constructing a shroud over the sampling train and flooding the shroud with helium gas. A
calibrated helium gas detector will be utilized to measure helium concentrations within the
shroud. 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 soil gas point are less than 10% of the helium concentrations
measured within the shroud.

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/crescent communities (cre)/cre-002
rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
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.
Following sample collection, the Summa® canisters will be shipped or delivered to a certified
laboratory under standard chain-of-custody protocols for analysis.

After sampling is complete, the sample locations will be estimated using a hand-held GPS unit,
and the sample locations will be abandoned by filling the void of the sample point with hydrated
bentonite.

3.3 Groundwater Sampling Activities

H&H proposes to install three temporary groundwater monitoring wells (TMW-5 through
TMW-7) in located depicted on Figure 2. The temporary well borings will be advanced with a
track-mounted drill rig capable of utilizing hollow-stem auger drilling techniques. During
drilling, soil cuttings will be collected and logged for lithologic description and field screened for
the presence of staining and elevated organic vapors using a calibrated PID. The temporary
monitoring wells will be constructed of 2-inch diameter PVC with 10 to 15 ft of pre-packed well
screen set to bracket the water table and 2-inch diameter PVC well casing to the ground surface.
Additional filter sand will be placed from the bottom of the borings to approximately 2 ft above
the top of the well screens. The temporary wells will be completed by placing a hydrated
bentonite seal from the top of the sand filter pack to the ground surface.

Once the temporary monitoring wells are installed, the wells will be allowed at least 24 hours to
equilibrate to static conditions and a decontaminated electronic water level indicator will be used
to measure the stabilized depth to the water table in each well relative to the top of the well
casing and to the adjacent ground surface. The wells will then be developed by removing a
minimum of 3 to 5 well volumes and until field parameters have stabilized (pH ± 0.1 standard
units [SU] and conductivity varies no more than 5%) and development water is visibly clear of
suspended sediment.
11

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/crescent communities (cre)/cre-002
rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
After development, a groundwater sample will be collected utilizing low flow/low stress purging
techniques using a peristaltic pump and dedicated polyethylene tubing. The intake point of the
pump tubing will be placed in the approximate mid-portion of the screened interval of the well
and groundwater will be removed at a rate no greater than 200 milliliters per minute. H&H will
utilize water quality meters to collect measurements of pH, temperature, dissolved oxygen,
oxidation reduction potential, turbidity, and specific conductivity at three- to five-minute
intervals during the purging process. Purging will be considered complete when the parameters
stabilize (pH ± 0.1 SU, conductivity varies no more than 5%, and turbidity is less than 10
Nephelometric Turbidity Units).

Once groundwater parameters stabilize, the groundwater samples for VOC analysis will be
collected directly into laboratory-supplied sample containers using the “soda straw” method to
minimize volatile loss through the peristaltic pump head. Samples collected for the remaining
analyses will be collected directly into laboratory-supplied sample containers from the dedicated
sample tubing through the peristaltic pump head. The sample containers will be delivered to a
North Carolina-certified laboratory under standard chain-of-custody protocols.

Groundwater samples will also be collected from on-Site water supply wells WSW-1 (northern
portion of the Site) and WSW-2 (central portion of the Site). Prior to sample collection, H&H
will purge the wells by allowing an exterior spigot to fun for approximately 20 to 30 minutes.
During water supply well purging, H&H will utilize water quality meters to collect
measurements of pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and
specific conductivity at three- to five-minute intervals during the purging process. Purging will
be considered complete when the parameters stabilize (pH ± 0.1 SU, conductivity varies no more
than 5%, and turbidity is less than 10 Nephelometric Turbidity Units).

Once groundwater parameters stabilize, the groundwater samples will be collected directly into
laboratory-supplied sample containers and delivered to a North Carolina-certified laboratory
under standard chain-of-custody protocols.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
4.0 Laboratory Analyses

The samples will be placed in dedicated laboratory supplied-sample containers and labeled with
the sample identification, date, and requested analysis. Soil samples collected from borings SB-2
and SB-3 will be analyzed for TCLP chromium by EPA Method 6020; soil samples collected
from borings SB-4 through SB-6 will be analyzed for VOCs by EPA Method 8260, SVOCs by
EPA Method 8270, RCRA metals by EPA Methods 6020/7470, and hexavalent chromium by
EPA Method 7199; soil gas samples will be analyzed for VOCs by EPA Method TO-15
(including naphthalene); groundwater samples collected from temporary wells TMW-5 through
TMW-6 will be analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and
RCRA metals by EPA Methods 6020/7470; and groundwater samples collected from water
supply wells WSW-1 and WSW-2 will be analyzed for PFAS by Draft EPA Method 1633.

Laboratory reporting limits for each analyte will be at or below appropriate 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.

rhyne road assemblage/brownfields/brownfields assessment/work plan/bf work plan rev. 1 - rhyne road (4-28-23).doc
5.0 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. One duplicate soil, soil gas,
temporary well sample, and water supply well sample will be collected for QA/QC purpose. The
duplicate 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 samples will be delivered to a laboratory under standard chain of custody protocols for
the same laboratory analyses as the parent sample.

Additional QA/QC procedures will be implemented due to the sampling for PFAS. These
procedures include decontamination of drilling and sampling equipment using PFAS-free water
and implementation of PFAS sampling procedures as shown on the attached PFAS Sampling
Checklist. A field blank and trip blank will also be collected for QA/QC purposes. The field
blank will be collected by pouring PFAS-free water directly into the laboratory-supplied sample
containers. The field blank will be analyzed for PFAS by Draft EPA Method 1622, and the trip
blank will be analyzed for PFAS by Draft EPA Method 1622 and VOCs by EPA Method 8260.

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.

6.0 Investigation Derived Waste (IDW) Management

IDW comprised primarily of soil cuttings generated during the proposed assessment activities
will be managed in general accordance with 15A NCAC 02T.1503 and 15A NCAC 02H. 0106.
H&H anticipates that soil cuttings, well development/purge water, and decontamination fluids
will be thin spread on-Site near the sample locations. However, if significant impacts are
suspected or observed (i.e., free-product), IDW will be containerized in labeled 55-gallon drums
and staged on-Site pending analytical results of composite IDW samples.

7.0 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 title page
consistent with the requirements in the Site Assessment Work Plan Checklist, a description of
Site activities, rationale for potential deviations from the work plan (if warranted), figures
depicting current/former sample locations/data with a redevelopment plan overlay, plume map(s)
(if warranted), tabular summaries of the new and historical sampling data, borings logs,
laboratory analytical data, field notes, a discussion of the data in comparison to regulatory
