1.0 Introduction and Background

On behalf of Mill District Partners LLC (Prospective Developer, PD), Hart & Hickman, PC (H&H)
has prepared this report summarizing post-construction sampling activities completed at the
pavilion structure at the North Davidson II North Carolina Department of Environmental Quality
(DEQ) Brownfields property (Brownfields Project No. 24003-20-060). The Brownfields property
is located at 2315 N. Davidson Street and 421 E. 26th Street in Charlotte, Mecklenburg County,
North Carolina (Site or subject Site). A Brownfields Agreement between DEQ and the PD was
recorded for the Site on June 9, 2021. The Site has been developed for non-residential use by Mill
District Partners, LLC which also manages the property. A Site location map is included as
Figure 1, and a Site layout map is included as Figure 2.

The Site consists of two parcels of land (Parcel Identification Numbers 08305204 and 08305206)
that total approximately 3.8 acres and are separated by a pedestrian walkway that replaced an
inactive rail corridor. The southeastern parcel (2315 N. Davidson Street) is developed with an
approximate 29,000-square foot (sq ft) commercial building that was retrofitted to a commercial
space known as the Urban District Market (UDM) food hall and office spaces. The northwestern
parcel (421 E. 26th Street) is developed with an approximate 16,800-sq ft building that was
retrofitted for Seoul Food Company, a commercial restaurant and entertainment space. A pavilion
structure (Pavilion) was also constructed in between the two buildings which consists of a partially
enclosed kitchen with a concession-style serving window. This report pertains to the post-
construction sampling activities for the Pavilion. Vapor intrusion mitigation system (VIMS)
activities for the 421 E. 26th Street building and 2315 N. Davidson Street building are documented
under separate cover.

Davidson & E. 26th/VIMS/Pavilion Structure/Sampling/2024-01/Text/24003_North Davidson II_VIMS Post-Occ
Report_Pavillion_3.29.24.docx
The Pavilion is a one-story, partially enclosed building that is approximately 420 sq ft in area.
Unlike the other two buildings at the Site, the Pavilion was built as new construction. The Pavilion
will be utilized for restaurant services and includes a small kitchen and service window with
exterior (non-enclosed) guest seating areas. To date, the Pavilion has not been occupied by a tenant
and remains unused.

To address potential environmental concerns in connection with the Site, a Brownfields Agreement
between the DEQ and the PD was recorded for the Site on June 9, 2021. Land Use Restriction
(LUR) h. included in the Brownfields Agreement generally states that no enclosed building on the
property may be occupied until DEQ determines in writing that the building would be protective
of users from risks of potential vapor intrusion. Historical assessments at the 421 E. 26th Street
parcel prior to redevelopment indicated acceptable risk levels. However, historical assessment
activities at the 2315 N. Davidson Street building indicated the presence of trichloroethylene
(TCE) and tetrachlorethylene (PCE) in sub-slab vapor samples at concentrations above their
respective screening limits (see Appendix A). Therefore, as a precaution for potential future
migration of site contaminants, specifically TCE and PCE, a passive VIMS was installed at the
Seoul Food building and an active VIMS was installed in the 2315 N. Davidson Street building in
accordance with the Vapor Intrusion Mitigation Plan – Revision 2 (VIMP) dated May 6, 2021.

A VIMS was not installed in the Pavilion. As discussed with DEQ via email and phone call
regarding the Pavilion structure, two post-construction sampling events were required to evaluate
risks from vapor intrusion into the Pavilion: one sampling event after the pavilion structure was
complete and another approximately six months after completion. In a call with DEQ in December
of 2023, DEQ stated that if vapor intrusion assessment data for the Pavilion indicates acceptable
indoor air conditions for two consecutive post-construction sampling events, no further sampling
at the Pavilion or retrofitting of the Pavilion with a VIMS will be necessary. A summary of the
two semi-annual post-construction sampling events is discussed in the sections below.

2.0 Post-Construction Sampling Activities

Post-construction sampling included collecting one sub-slab vapor sample and one indoor air
sample during each sampling event. Comparison of the sub-slab vapor sample data to the indoor
air sample data allows for evaluation of potential vapor intrusion pathways and potential above-
slab interference due to potential off-gassing of vapors from construction materials. In order to
collect a sub-slab vapor sample from the pavilion structure, H&H installed a sub-slab Cox-
Colvin® Vapor Pin® (Vapor Pin) in the center of the pavilion structure which is identified as
MP-P1. The Vapor Pin monitoring point was finished with a rubber cap and flush-mounted
stainless-steel cover per standard manufacturer installation procedures. A photographic log of the
pavilion structure is included as Appendix B.

H&H performed post-construction sampling after construction of the Pavilion was completed in
May 2023 and approximately eight months later in January 2024. The sub-slab vapor and indoor
air sampling activities were conducted in general accordance with the DEQ-approved VIMPs for
the other two Site buildings and the DEQ DWM Vapor Intrusion Guidance (Guidance) dated
March 2018. Details regarding the sub-slab vapor and indoor air sampling methodology and
results are described in the sections below.

2.1 Sub-Slab Vapor Sampling Methodology

On May 17, 2023, and January 18, 2024, H&H collected one sub-slab vapor sample from a
monitoring point (identified as P-1 or MP-P1) installed within the Pavilion for comparison to
indoor air sample analytical data. The sub-slab vapor sample was collected following collection
of the indoor air sample (Section 2.3) to avoid potential interference with the indoor air sampling
during opening and purging of the monitoring point.

At the monitoring point, Teflon sample tubing was secured to the Vapor Pin and connected to an
airflow regulator and laboratory-supplied batch-certified 1-liter stainless steel Summa canister.
The airflow regulator was preset by the laboratory to collect a vapor sample at a flow rate of
approximately 100 milliliters per minute.

Report_Pavillion_3.29.24.docx
Upon Summa canister receipt, H&H performed a shut-in test to verify the canister and regulator
were properly sealed by the laboratory. Prior to sample collection, H&H conducted a leak test at
the monitoring point by placing a shroud around the monitoring point and sampling train including
the Summa canister. The air within the shroud was flooded with helium gas and concentrations
were measured with a calibrated helium detector. Helium concentrations by volume within the
shroud were maintained between approximately 10% to 15%. A small air pump was connected to
the sample tubing outside of the shroud and used to purge a minimum of three sample train
volumes into a Tedlar® bag at the sampling point. The helium gas detector was used to measure
helium concentrations within the Tedlar® bag sample to confirm helium concentrations in the
sample were less than 10% of that measured within the shroud. Results of the helium leak checks
indicate that short-circuiting at the monitoring point or within the sampling train did not occur.
Sub-slab vapor sample field forms completed by sampling personnel are included in Appendix C.

Following a successful leak check, the airflow regulators were opened to allow collection of the
sub-slab vapor sample. The vacuum in the Summa canister was monitored during the sampling
event to confirm adequate sample volume was collected from the monitoring point. Per laboratory
standard operating procedures, a vacuum of approximately 5 inches of mercury (inHg) was
maintained within the canister at the conclusion of the sampling events. Upon completion of
sample collection, the airflow regulator was closed to the Summa canister. The canisters were
labeled with the sample identification, date, time, starting and ending vacuums, and requested
analysis. The canisters were then placed in laboratory-supplied shipping containers and delivered
to Waypoint Analytical (Waypoint) under standard chain of custody protocols for analysis of
volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method TO-15.

2.2 Sub-Slab Vapor Sampling Results

A tabular summary of the sub-slab vapor sample analytical results is provided in Table 1. As the
building is for commercial purposes, the sub-slab vapor sample laboratory analytical results were
compared to the DEQ DWM Non-Residential Soil Gas Screening Levels (SGSLs) dated February
2024. The laboratory analytical reports with chain of custody records are provided as
Appendix D. Note, during the January 2024 sampling, indoor air samples were also collected at

Davidson & E. 26th/VIMS/Pavilion Structure/Sampling/2024-01/Text/24003_North Davidson II_VIMS Post-Occ
Report_Pavillion_3.29.24.docx
the 2315 N. Davidson Street and 421 E. 26th Street buildings during the same sampling event.
Therefore, these samples are included in the analytical laboratory reports but the data from these
samples will be reported under separate cover.

Laboratory analytical results indicate the presence of several VOCs detected above laboratory
method detection limits (MDLs) during both sampling events, but all the detected compound
concentrations are below the DEQ Non-Residential SGSLs. TCE, the primary contaminant of
concern (COC) on the Site, was not detected in the sub-slab sample from MP-P1 during either
sampling event.

Risk Calculations
The DEQ DWM Vapor Intrusion SGSLs used for comparison to the laboratory analytical results
are conservative and based on a target carcinogenic risk (TCR) for potential carcinogenic risks of
1.0 x 10-6 and a non-carcinogenic hazard quotient (HQ) of 0.2. The DEQ acceptable level for
potential carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR) of 1.0 x 10-4
or less, and the acceptable level for non-carcinogenic risks is a cumulative hazard index (HI) of
1.0 or less. The HI is the sum of HQs for each detected compound.

To further evaluate potential health risks associated with the sub-slab vapor concentrations, H&H
used DEQ’s Risk Calculator dated February 2024 to calculate cumulative risk levels using MP-P1
data from both sampling events. Results of the risk calculations for a non-residential use scenario
are shown in the table below and included in Table 1, and the DEQ Risk Calculator input/output
summaries are provided as Appendix E.

Sample Date Sample Location Cumulative LICR Cumulative HI
May 17, 2023 P-1 1.2 x 10-7 0.0052
January 18, 2024 MP-P1 3.2 x 10-8 0.0048

As shown in the table above, risk calculator results indicate that calculated cumulative LICR values
and HI values are below the acceptable risk levels for a non-residential use scenario. These sub-
slab vapor sample results and risk calculations indicate that VOC concentrations below the slab

Report_Pavillion_3.29.24.docx
are not present at levels that would pose an unacceptable risk to the commercial occupants of the
pavilion structure.

2.3 Building Survey Activities

Prior to beginning sub-slab vapor and indoor air sampling activities, H&H completed a survey in
the building to identify materials used or stored in the building that may contain COCs. No storage
or use of chemicals with COCs, such as TCE or other chlorinated solvents, was identified during
the sampling event. Because the Pavilion is not currently occupied by a tenant, the building was
under fully closed conditions during sampling, which is considered more conservative than likely
normal operating conditions when the vendor service window would be opened and interior air in
the conjoined kitchen would be actively vented out of the Pavilion. A copy of the indoor air
building survey completed during the day of sampling is provided as Appendix C.

2.4 Indoor Air Sampling Methodology

Prior to collecting sub-slab vapor samples on May 17, 2023, and January 18, 2024, H&H collected
one indoor air sample from the center of the pavilion (identified as P-1 or IAS-P1) for laboratory
analysis within the Pavilion. Upwind exterior background air samples, BKG-051723 and
IAS-BKG, were collected concurrently with the indoor air samples to evaluate compound
concentrations in ambient outdoor air. Additionally, one duplicate indoor air sample was collected
during each sampling event. During the first post-construction sampling event in May 2023, the
duplicate was collected from another building at the Site that was sampled at the same time as the
Pavilion. During the second post-construction sampling event in January 2024, the duplicate (IAS-
DUP) was collected along with the parent indoor air sample, IAS-P1. The duplicate samples were
collected by utilizing a laboratory-supplied stainless-steel sampling “T”, which allows for the
simultaneous collection of two indoor air samples from a single location. The indoor air sample
location is shown on Figure 3.

The indoor air samples were collected using laboratory-supplied 6-liter stainless steel Summa
sample canisters connected to in-line flow controllers with a vacuum gauge. The Summa canisters

Davidson & E. 26th/VIMS/Pavilion Structure/Sampling/2024-01/Text/24003_North Davidson II_VIMS Post-Occ
Report_Pavillion_3.29.24.docx
used for the indoor air samples were individually-certified by the laboratory, while the Summa
canisters for the background air samples were batch-certified by the laboratory. The flow
controllers were calibrated by the laboratory to allow for sample collection over an approximate
8-hour period, which is consistent with a non-residential use scenario. Teflon tubing was
connected to the flow controller with the Teflon tubing elevated by a laboratory stand so that the
sample intake point was positioned approximately 5 ft above grade (typical breathing zone height)
when the sample canister was set on its base.

During sampling activities, indoor/outdoor air pressure differential was measured near the start,
middle, and end of the sampling period using a manometer sensitive to 0.001 inches of water
column (in-WC). In addition, barometric pressure, exterior wind speed, exterior wind direction,
and indoor/outdoor temperature were recorded near the start, middle, and end of the sampling
period. Results of differential pressure measurements indicated that there was no measurable
difference between the indoor and outdoor pressures during the sampling events. A summary of
the field measurement data collected at the time of the indoor air sampling event is included in
Appendix C.

For QA/QC purposes, H&H personnel periodically monitored the sample canisters to monitor
vacuum pressures and prevent tampering or damage during the sampling event. Vacuum was
measured in each of the Summa canisters prior to and after sampling activities. Per laboratory
standard operating procedures, a vacuum of approximately 5 to 8 inches of mercury (inHg) was
maintained within the canisters at the conclusion of the sampling event. After approximately 8
hours of sampling, the samples were closed to air intake, properly labeled with the sample
identification, date, time, starting and ending vacuums, and requested analysis. The canisters were
then placed in laboratory-supplied shipping containers and delivered to Waypoint under standard
chain of custody protocols for analysis of VOCs by EPA Method TO-15. Note, the VIMP for the
other Site buildings included a Site-specific TO-15 list for indoor air sampling, but due to a lack
of VIMS and historical sampling at the footprint of the Pavilion, the indoor air samples were
analyzed by full-list VOCs.

Report_Pavillion_3.29.24.docx
2.5 Indoor Air Sampling Results

A tabular summary of the analytical results is provided in Table 1. The indoor air sample
laboratory analytical results were compared to the DEQ DWM Non-Residential Indoor Air
Screening Levels (IASLs) dated February 2024. The laboratory analytical reports and chain of
custody records are included in Appendix D.

The indoor air sample analytical results indicate that several compounds were detected at
concentrations above laboratory MDLs in the indoor air samples; however, none of these
concentrations were above the Non-Residential IASLs. TCE, the primary COC at the Site, was
not detected above laboratory MDLs during either of the indoor air sampling events. During the
January 2024 sampling event, TCE was detected at a concentration of 1.02 J µg/m3 in the ambient
outdoor background sample, which was located south of the 2315 N. Davidson Street building.

Risk Calculations
The DEQ DWM IASLs used for comparison to the laboratory analytical results are conservative
and based on a TCR for potential carcinogenic risks of 1.0 x 10-6 and a non-carcinogenic HQ of
0.2. The DEQ acceptable level for potential carcinogenic risks is a cumulative LICR of 1.0 x
10-4 or less, and the acceptable level for non-carcinogenic risks is a cumulative HI of 1.0 or less.
The HI is the sum of HQs for each detected compound.

To further evaluate potential health risks posed by indoor air conditions, H&H used DEQ’s Risk
Calculator dated February 2024 to calculate cumulative carcinogenic and non-carcinogenic risk
levels using May 2023 and January 2024 indoor air data. Results of the risk calculations for a non-
residential use scenario are shown in the table below and included in Table 1, and the DEQ Risk
Calculator input/output summaries are provided as Appendix E.

Sample Date Monitoring Point Cumulative LICR Cumulative HI
May 17, 2023 P-1 3.5 x 10-7 0.049
January 18, 2024 IAS-P-1 / IAS-DUP 7.7 x 10-7 0.029

As shown in the table above, risk calculator results indicate that the cumulative LICR and HI
values are below the DEQ acceptable risk levels for a non-residential use scenario. These indoor
air sample results and risk calculations indicate that concentrations of compounds in indoor air are
not present at levels that would pose an unacceptable risk to the commercial occupants of the
Pavilion structure.

3.0 Summary, Conclusions, and Recommendations

H&H has completed the two semi-annual post-construction sub-slab vapor and indoor air sampling
events at the pavilion structure located on the North Davidson II Brownfields Property in Charlotte,
North Carolina. The results of the post-construction activities indicate the following:

 In May 2023 and January 2024, H&H collected one indoor air sample and one sub-slab
vapor sample from the Pavilion. No VOCs were detected above the Non-Residential
SGSLs or Non-Residential IASLs.
 The main Site contaminant of concern, TCE, was not detected in any of the indoor air or
sub-slab vapor samples above the laboratory MDLs.
 The results of cumulative risk calculations for both post-construction sampling events
indicate that carcinogenic and non-carcinogenic risk levels are below DEQ acceptable
levels for a non-residential use scenario.

Recommendations
Based on the results of vapor intrusion assessment and conclusions presented above, H&H requests
no vapor intrusion mitigation and no further post-construction sampling be required at the Pavilion
structure.

Notes:
1) North Carolina Department of Environmental Quality (DEQ) Division of Waste Management (DWM) Vapor Intrusion Indoor Air Screening Levels (IASLs) dated February 2024 and based upon TCR = 1 x 10-6 and THQ = 0.2.
2) North Carolina Department of Environmental Quality (DEQ) Division of Waste Management (DWM) Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated February 2024 and based upon TCR = 1 x 10-6 and THQ = 0.2..
3) NCDEQ DWM Cumulative Risk Calculator dated February 2024. Cumulative LICR and HI calculated using the worst-case scenario and compared to DEQ and EPA acceptable risk levels for carcinogenic and non-carcinogenic risks.
Green highlighted results are from the most recent sampling event.
Concentrations are reported in micrograms per cubic meter (µg/m3).
Laboratory analytical method is shown in parentheses.
Only compounds detected in at least one sample are shown in the above table.
Bold values indicate an exceedance of DWM Non-Residential IASL or SGSL.
TCR = Target Cancer Risk; THQ = Non-Carcinogenic Target Hazard Quotient; LICR = Lifetime Incremental Cancer Risk; HI = Hazard Index
VOCs = volatile organic compounds; NE = not established.
J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.
B = Compound was detected in the laboratory method blank.

Dear Matt Vawter:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 1/19/2024 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,
Angela D Overcash Senior Project Manager

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic
risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic
risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.
