Vapor Intrusion Monitoring Work Plan REEP-LRC(RN) 1900 and 1942 Continental Boulevard Charlotte, North Carolina Brownfields Project No. 24001-20-060 H&H Job No. SSP-001 1.0 Introduction

On behalf of SPWF-Continental Warehouse, LLC (Prospective Developer or PD), Hart & Hickman,
PC (H&H) has prepared this Vapor Intrusion Monitoring Work Plan (Work Plan) for the REEP-
LRC(RN) (a.k.a REEP-LRC II) Brownfields property (Brownfields Project No. 24001-20-060)
located at 1900 and 1942 Continental Boulevard in Charlotte, Mecklenburg County, North Carolina
(Site). The Site consists of two parcels of land that total approximately 85.2 acres, which include
Mecklenburg County Parcel Identification Number [PIN] 20308301 (1900 Continental Boulevard)
and vacant wooded land east of Interstate I-485 with no established address (PIN 20302139). 1900
Continental Boulevard is developed with an approximately 1,370,000 square foot (sq ft) warehouse
building located to the west of Interstate I-485 (hereinafter referred to as the “warehouse parcel”). The
Site building is currently used for warehousing, manufacturing, and distribution. A Site location map
is provided as Figure 1.

On March 2, 2023, the North Carolina Department of Environmental Quality (DEQ) Brownfields
Redevelopment Section provided the PD with a draft Brownfields Agreement (BFA) for review.
Based on a proposed Land Use Restriction (LUR) included in the draft BFA, and associated
conference calls with the PD, PD’s legal counsel, and H&H, DEQ is requesting quarterly vapor
intrusion assessment in the warehouse building for up to a minimum period of one year. As it relates
to the warehouse parcel, a brief summary of background information, current tenant status, and results
of previously conducted environmental assessment activities is presented in Section 2.0. The proposed
vapor intrusion monitoring scope of work is described in Section 3.0.

2.0 Background Information

2.1 Site History and Current Tenant Status
The Site and surrounding area were formerly occupied by the United States Navy from approximately
1949 through 1967. Former use of the Site as a Naval Ammunitions Depot (NAD) included operations
consisting of numerous buildings surrounded by protective soil berms based on a 1950 aerial
photograph and a 1950 map of the former NAD. Following NAD operations, the Site was occupied
by Continental Tire and used for tire manufacturing from 1967 through 2013.

The existing warehouse building is divided into the following tenant spaces, which are identified in
Figure 2:

• Suites A, G, and H – Spirit Halloween
• Suite B – Professional Builders Supply
• Suite C – Harris Tire
• Suite D – Darnell
• Suites E and F – Synders Lance
• Suite I – United States Postal Service (USPS)
• Suite J – Siemens/ Deufol Charlotte, LLC
• Suite K – SnapAV

2.2 Summary of Previous Environmental Assessment Activities – Warehouse Parcel
Multiple phases of environmental assessments have been conducted at the Site since 2007. The
assessments were conducted under the purview of the DEQ Underground Storage Tank (UST)
Section, Inactive Hazardous Sites Branch (IHSB), and the Brownfields Program. Known releases
associated with the warehouse parcel include the former Wash Rack area (UST Section No Further
Action status in June 2010), the former Boiler Day Tanks area (UST Section No Further Action status
in June 2010), the former Naphtha UST area (UST Section Conditional No Further Action status and
Notice of Residual Petroleum filed in 2003), the former Rail Off-Loading Area (UST Section

Conditional No Further Action status in January 2020), and the former Buffing Dust Shed (active
IHSB incident). H&H understands that Continental Tire is identified by DEQ as the responsible party
for the active Buffing Dust Shed IHSB incident and that ongoing off-Site vapor intrusion assessment
activities are currently underway.

In 2009, soil assessment activities were completed in the southeast portion of the warehouse parcel to
evaluate subsurface conditions associated with the former Buffing Dust Shed IHSB incident. The
results of those activities indicated low levels of volatile organic compounds (VOCs) were detected
in surficial soil samples at concentrations above laboratory detection limits, but below the DEQ
Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs). In addition, low levels of
several metals were detected at concentrations above the laboratory method detection limits, but below
the DEQ Industrial/Commercial PSRGs and/or within naturally occurring background levels for North
Carolina soils.

Since 2009, groundwater assessment activities conducted on the warehouse parcel have identified
multiple compounds at concentrations above the DEQ 15A North Carolina Administrative Code
(NCAC) 02L .0202 Groundwater Quality Standards (2L Standards). Compounds detected above 2L
Standards include but are not limited to, iron and manganese, polycyclic aromatic hydrocarbons
(PAHs), and the VOCs benzene, 1,1-dichloroethane, 1,2-dichloroethane, carbon tetrachloride,
tetrachloroethylene (PCE), trichloroethylene (TCE), and vinyl chloride.

From 2019 through 2022, H&H completed vapor intrusion assessment activities in the warehouse
building as part of property transaction due diligence (2019) and under the purview of the Brownfields
Redevelopment Section (2021 through 2022). The assessment activities included the collection of
sub-slab vapor samples in 2019 and 2021 and sub-slab vapor samples with co-located indoor air
samples in 2022. A summary of the vapor intrusion assessment results is provided in Appendix A and
briefly described below.

Sub-slab vapor laboratory analytical results for all sampling events indicated 1,1-dichloroethane (up
to 3,700 micrograms per cubic meter [µg/m3]) was detected at concentrations above the DEQ Non-
Residential Sub-Slab and Exterior Soil Gas Screening Level (SGSL) in sub-slab vapor samples SS-9

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/somerset properties (ssp)/continental tire (ssp-001)/vi monitoring/final to deq/rev 3 vi monitoring work plan_ reep-lrc(rn).docx
and SS-19 located within the Siemens/Deufol tenant space (Suite J). Additionally, TCE (1,200 µg/m3)
was detected at a concentration above the Non-Residential SGSL in sub-slab vapor sample SS-21
located within the USPS tenant space (Suite I). TCE was not detected above the Non-Residential
SGSL in any other sub-slab vapor sample collected during the assessment activities.

As previously mentioned, vapor intrusion assessment activities completed in 2022 included the
collection of sub-slab vapor with co-located indoor air samples. Indoor air laboratory analytical results
from this sampling event indicated petroleum-related compounds ethylbenzene and naphthalene were
detected above the DEQ Non-Residential Indoor Air Screening Levels (IASLs) in the SnapAv,
Siemens Deufol, USPS, Darnell, and Spirit Halloween tenant spaces. No others VOCs were detected
above the Non-Residential IASLs. Additionally, TCE was not detected above the laboratory reporting
limit (0.13 µg/m3) in indoor air samples (IA-5 and IA-6) collected from the USPS tenant space.

H&H further evaluated the indoor air sampling results using the DEQ risk calculator to evaluate
calculated cumulative risks in each sampled tenant space. The results of the risk evaluation indicated
that calculated cumulative risk values for indoor air for a non-residential worker were within the
acceptable carcinogenic risk of less than 1 x 10-4 and less than a hazard index of 1.0. Additionally, a
comparison of sub-slab vapor and indoor air results using a non-residential attenuation factor of 0.01
(NCDEQ Risk Calculator User Guide dated February 2021) indicates the potential for indoor sources
and/or outdoor sources to be notable contributors to cumulative risk values for indoor air. Potential
indoor sources could include emissions from plastic materials such as those stored in the Spirit
Halloween tenant space, which is associated with the highest concentrations of ethylbenzene and
naphthalene (indoor air sample IAS-10). Potential outdoor sources could include vehicular exhaust
from the loading locks located along the permitter of the warehouse building.

To address DEQ’s proposed LUR for quarterly vapor intrusion monitoring at the Site, H&H is
submitting this Vapor Intrusion Monitoring Work Plan (Work Plan), the details of which are included
in the following sections.

3.0 Vapor Intrusion Monitoring Activities
The proposed vapor intrusion monitoring activities will be performed in general accordance with the
DEQ IHSB Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines) dated
September 2022, the DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance dated
March 2018, Brownfield’s Vapor Intrusion Assessment Work Plan & Report Checklist (VI Checklist)
dated July 2021, and the most recent versions of the U.S. EPA Region IV Laboratory Services and
Applied Science Division (LSASD) Field Branches Quality System and Technical Procedures
guidance.

Prior to conducting field activities, H&H will contact North Carolina 811 One-Call, the public utility
locator service, to mark subsurface utilities at the Site, where feasible.

3.1 Sub-Slab Vapor Intrusion Assessment Activities
On a quarterly basis, H&H proposes to conduct sub-slab vapor assessment activities to monitor the
potential for structural vapor intrusion into the warehouse building. The proposed sampling locations
are representative of areas where TCE was detected in indoor air above laboratory reporting limits
(IAS-10 and IAS-1) and in sub-slab vapor above the Non-Residential SGSL (SS-21). The
approximate locations of the sub-slab vapor samples are shown on Figure 2 (with yellow highlighting)
and are further described below.

• SS-13 (co-located with indoor air sample IAS-10) will be located in the Spirit Halloween
tenant space (Suite H);
• SS-17 (co-located with indoor air sample IAS-1) will be located in the SnapAV tenant space
(Suite K); and
• SS-21 (co-located with indoor air sample IAS-5) will be located in the USPS tenant space
(Suite I).

H&H proposes to install each sub-slab vapor monitoring point by using a hammer drill and a 5/8-inch
diameter decontaminated drill bit to advance the boring through the concrete slab. Slab thicknesses
and sub-slab materials (i.e., soil, gravel, etc.) will be documented at each location. Following concrete

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/somerset properties (ssp)/continental tire (ssp-001)/vi monitoring/final to deq/rev 3 vi monitoring work plan_ reep-lrc(rn).docx
borehole advancement, loose concrete cuttings will be removed from the boring using a bottlebrush
and vacuum with a high-efficiency particulate air (HEPA) filter. A Cox-Colvin Vapor Pin™ (vapor
pin) assembly (brass sampling point and silicone sleeve) will be seated in the borehole using an
installation/extraction tool and hammer. The vapor pin will be connected at the surface with ¼-inch
new and dedicated Teflon® tubing and will be installed as temporary sub-slab gas points. Sample
points will be allowed to equilibrate for at least two hours following installation.

Prior to vapor sampling activities, a leak check will be conducted by constructing a shroud around the
sample train at each sub-slab vapor 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 10% to 20% for the duration of the leak check. Using
a syringe and three-way valve, a minimum of three sample train volumes (including both the tubing
and annulus) will be purged at a maximum flow rate of 200 mL/min, and a sample will be collected
from the sample tubing outside the shroud into a Tedlar bag and analyzed using the helium gas detector
to ensure that helium concentrations are less than 10% of the helium concentrations measured within
the shroud. Note that the helium meter will not be connected to the sampling train, as it is used
independently to measure helium within the shroud and from a Tedlar bag that is connected to the
sampling train.

Following a successful leak check, the samples will be collected using batch-certified 1-liter or 3-liter
stainless steel Summa® canisters connected to an air-flow regulator calibrated by the laboratory for
collection of a sample at a rate of up to approximately 100 milliliters per minute. To conduct the
sampling, the intake valve on the Summa® canister will be fully opened to begin collection of the
sample and 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 will be maintained
within the canisters at the conclusion of the sampling event, and vacuum measurements which include
pre- and post-sampling, and sample collection time durations will be recorded on the chain-of-custody.
Canisters that have lost greater than 10% of their vacuum as determined by comparing the vacuum
recorded by the laboratory prior to shipment and the vacuum recorded in the field during the leak test
procedures will not be used for sampling. In addition, a minimum vacuum of five inches of mercury
will be maintained on the sample canisters until the conclusion of the sampling event.

After sample collection, the intake valve will be closed, and the regulator will be disconnected from
the sample canister. The canisters will be placed in laboratory-supplied shipping containers, properly
labeled, and shipped under standard chain-of-custody protocols to Contest, a Pace Analytical
Laboratory, for analysis of volatile organic compounds (VOCs) by EPA Method TO-15. Table 1
summarizes the proposed sub-slab vapor samples and associated analyses. To evaluate the
reproducibility of the sample results, H&H will collect one duplicate sub-slab vapor sample for the
analysis of VOCs by EPA Method TO-15. Information pertaining to Contest’s certifications and
accreditations for TO-15 in Massachusetts is provided in Appendix B.

Upon completion of sampling activities, sub-slab vapor point locations will be recorded in the field
using a hand-held GPS unit, where possible.

3.2 Indoor Air Assessment Activities
Prior to the collection of the sub-slab vapor samples, H&H will collect three indoor air samples (IAS-
1, IAS-5, and IAS-10) within the building. The approximate locations of the indoor air samples are
shown on Figure 2 with yellow highlighting and described below.

• IAS-10 (co-located with sub-slab vapor sample SS-13) will be located in the Spirit Halloween
tenant space (Suite H);
• IAS-1 (co-located with sub-slab vapor sample SS-17) will be located in the SnapAV tenant
space (Suite K); and
• IAS-5 (co-located with sub-slab vapor sample SS-21) will be located in the USPS tenant space
(Suite I).

The indoor air samples will be collected using individually-certified 6-liter stainless steel Summa
sample canisters connected to an in-line flow controller with a vacuum gauge. The flow controllers
will be set by the laboratory to allow for collection of the sample over an 8-hour period. A 3-foot long
sampling cane will be connected to the flow controller so that the sample intake point is positioned

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/somerset properties (ssp)/continental tire (ssp-001)/vi monitoring/final to deq/rev 3 vi monitoring work plan_ reep-lrc(rn).docx
approximately 5 ft above grade (typical breathing zone height) when the sample canister is set on its
base.

During the sampling activities, indoor/outdoor air pressure differential will be measured near the start,
middle, and end of the 8-hour sampling period using a manometer sensitive to 0.001 inches of water.
In addition, exterior wind speed, exterior wind direction, indoor/outdoor temperature, and
precipitation (if any) will be recorded near the start, middle, and end of the sampling period. For
quality assurance purposes, H&H personnel will be on-Site monitoring the sample canister to prevent
tampering or damages for the duration of the sampling event, if the tenant space is occupied at the
time of sampling. A vacuum will be maintained within the canister at the conclusion of the sampling
event.

After sample collection, the intake valve will be closed, and the regulator will be disconnected from
the sample canister. The canisters will be placed in laboratory-supplied shipping containers, properly
labeled, and shipped under standard chain-of-custody protocols to Contest for analysis of select VOCs
by EPA Method TO-15. Table 1 summarizes the proposed indoor air samples and associated analyte
list. To evaluate the reproducibility of the sample results, H&H will collect one duplicate indoor air
sample for the analysis of VOCs by EPA Method TO-15. Information pertaining to Contest’s
certifications and accreditations for TO-15 in Massachusetts is provided in Appendix B. Any
proposed changes to the list of approved analytes must be submitted in writing to DEQ, and DEQ's
written consent must be obtained before implementation.

Upon completion of sampling activities, indoor air sampling locations will be recorded in the field
using a hand-held GPS unit, where possible.

3.3 Quality Assurance/Quality Control Samples
Non-dedicated equipment and tools will be decontaminated prior to use at each sampling location or
following exposure to sub-slab gas samples. Decontamination of non-dedicated equipment will follow
U.S. EPA Region IV guidance (LSASDPROC-205-R4) and will consist of wiping the equipment
clean, a water-rinse of the equipment, washing the equipment in water and detergent (i.e., Liquinox®

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/somerset properties (ssp)/continental tire (ssp-001)/vi monitoring/final to deq/rev 3 vi monitoring work plan_ reep-lrc(rn).docx
or Luminox®), and a final rinse with water. The process will be repeated for grossly contaminated
non-dedicated equipment.

For quality assurance and quality control purposes (QA/QC), and to evaluate the reproducibility of
the sample results, H&H will collect the following: 1) one duplicate sub-slab gas sample; and 2) one
duplicate indoor air sample. The duplicate samples will be submitted for the same laboratory analysis
as their respective parent samples. For the duplicate sub-slab gas and indoor air samples, H&H will
utilize a laboratory-supplied “T-sampler” which allows for the collection of two samples from the
same location simultaneously. Per laboratory standard operating procedures, a vacuum of
approximately five inches of mercury will be maintained within all canisters at the conclusion of the
sampling event.

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 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 (i.e., “J”
flags).

The laboratory analytical data report and QA package for each group of samples 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 requested 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.

3.4 Investigation Derived Waste (IDW)
No investigation derived waste (IDW) is expected to be generated during the vapor intrusion
assessment activities.
3.5 Reporting

Following the completion of each quarterly monitoring event and receipt of the analytical data, H&H
will document our findings in a Vapor Intrusion Monitoring Report. The report will include a
description of the sampling activities, pertinent figures (with appropriate graphic scale and north
arrow) depicting sample locations, tabulated sample data (reported to less than the reporting limit and
compared to applicable regulatory screening levels), laboratory analytical data, a discussion of the
data (including “J” flags) in comparison to applicable regulatory screening levels with notes where
the reporting limit exceeds the regulatory screening level, statistical analysis to evaluate trends and
Site-specific attenuation factors, for trend evaluation risk calculations, and conclusions and
recommendations concerning our activities. The report will be sealed by a North Carolina
Professional Engineer (PE) or Licensed Geologist (LG) and the firm PE/LG numbers will be provided.
