Brownfields Project No. 24003-20-060 H&H Job No. PAM-003
1.0 Introduction and Background

On behalf of Mill District Partners LLC, Hart & Hickman, PC (H&H) has prepared this report to
document vapor intrusion mitigation system (VIMS) installation inspections and efficacy testing
activities completed at the eastern portion of the 2315 N. Davidson Street building located at the
North Davidson II Brownfields property [North Carolina Department of Environmental Quality
(DEQ) Brownfields Project No. 24003-20-060]. The property address is listed as 2315 N.
Davidson Street and 421 E. 26th Street in Charlotte, Mecklenburg County, North Carolina (Site or
subject Site). A Site location map is provided as Figure 1 and the Site layout with the building
footprints are depicted on Figure 2.

The Site consists of two parcels of land (Parcel Identification Numbers 08305204 and 08305206)
that total approximately 3.8 acres. The southeastern parcel (2315 N. Davidson Street) is developed
with an approximate 28,700-square foot (sq ft) commercial building for restaurant and office use,
and the northwestern parcel (421 E. 26th Street) is developed with an approximate 13,000-sq ft
commercial restaurant building. Redevelopment at the Site includes adaptive re-use of the Site
buildings. The building located on the southeastern parcel of the Site (2315 N. Davidson Street)
has been retrofitted and occupied by commercial (restaurant style) tenants and is known as the
Urban District Market (UDM) Food Hall. Commercial offices (Office Space) will be in the eastern
portion of this building upon tenant lease. An active VIMS is currently installed in the UDM Food
Hall side of the building which was documented in the VIMS Installation Completion Report –
UDM Food Hall, dated February 17, 2023 and DEQ provided compliance approval for this area
in a letter dated March 2, 2023.

The separate building on the northwestern parcel of the Site (421 E. 26th Street) has been retrofitted
as a commercial restaurant and entertainment space that is occupied by Seoul Food Company. For

the 421 E. 26th Street building, the VIMS installation was documented in the VIMS Installation
Completion Report – 421 E. 26th Street Building, dated April 4, 2022, and DEQ provided
compliance approval in a letter dated April 25, 2022.

This report pertains to the eastern portion of the 2315 N. Davidson building which has been
retrofitted to be a future office (commercial) space. For simplicity, this area is referred to as the
Office Space in this report. As the Office Space construction and VIMS installation were not
completed at the time of the UDM construction completion and because a full demising wall is
present between UDM and the Office Space that completely separates the two sides, DEQ
approved via email on January 20, 2023, that the VIMS installation for each side of the building
could be provided in separate submittals.

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. Previous vapor intrusion assessment activities
indicated the presence of trichloroethylene (TCE) and tetrachlorethylene (PCE) at concentrations
above respective DEQ Division of Waste Management (DWM) Vapor Intrusion Sub-Slab and
Exterior Soil Gas Screening Levels (SGSLs) and Indoor Air Screening Levels (IASLs) in sub-slab
vapor and indoor air samples collected in the 2315 N. Davidson Street building.

In accordance with LUR h. in the Brownfields Agreement for the Site, H&H prepared a Vapor
Intrusion Mitigation Plan (VIMP) for the Site that included both Site buildings. In an email dated
May 7, 2021, the DEQ Brownfields Program provided approval for the VIMP – Revision 2 dated
May 6, 2021. The DEQ-approved VIMP includes installation of a VIMS during renovation of the
buildings to minimize the potential for vapor intrusion into the buildings using an active sub-slab
depressurization system.

H&H completed VIMS inspections, VIMS influence testing, and VIMS efficacy testing at the
Office Space in the 2315 N. Davidson Street building in accordance with the DEQ-approved

VIMP. Note, some components of the VIMS, such as the telemetric alarm system, are connected
between the UDM Food Hall and office areas of the building.

Previous site assessment data is included in Attachment A, the VIMS as-built drawings (Sheets
VM-1, VM-1A, VM-2, and VM-3) and product specifications for materials and components used
during installation of the VIMS are provided in Attachment B and C, respectively. A summary of
the VIMS installation and influence testing activities is provided in Section 2.0. The VIMS
efficacy sampling activities and results are detailed in Section 3.0, summary and conclusions based
on the installation activities, influence testing, and efficacy sampling are provided in Section 4.0,
and future monitoring activities are provided in Section 5.0.

Engineer’s Certification
According to the DWM Vapor Intrusion Guidance: “Risk-based screening is used to identify sites
or buildings likely to pose a health concern, to identify buildings that may warrant immediate
action, to help focus site-specific investigation activities or to provide support for building
mitigation and other risk management options including remediation.” In addition, this VIMP was
prepared to satisfy the standard vapor intrusion mitigation provisions anticipated to be included in
the Brownfields Agreement. Per the North Carolina Brownfields Property Reuse Act 130A-
310.32, a prospective developer, with the assistance of H&H for this project, is to provide DEQ
with “information necessary to demonstrate that as a result of the implementation of the
brownfields agreement, the brownfields property will be suitable for the uses specified in the
agreement while fully protecting public health and the environment instead of being remediated to
unrestricted use standards.” It is in the context of these risk-based concepts that the H&H
professional engineer makes the following statement:

“The Vapor Intrusion Mitigation System (VIMS) detailed herein is designed to mitigate intrusion
of subsurface vapors into the subject building from known Brownfields Property contaminants in
a manner that is in accordance with the most recent and applicable guidelines including, but not
limited to, DWM Vapor Intrusion Guidance, Interstate Technology & Regulatory Council (ITRC)
guidance, and American National Standards Institute (ANSI)/American Association of Radon
Scientists and Technologists (AARST) standards. The sealing professional engineer below is
satisfied that the design and its installation are fully protective of public health from known
Brownfields Property contaminants.

2.0 VIMS Installation and Influence Testing

The Office Space is located on the eastern portion of the 2315 N. Davidson Street building and is
separated by a demising wall from the adjacent UDM Food Hall located in the western portion of
the building. As indicated above, construction of the UDM portion of the building has been
completed and is currently occupied by restaurant tenants. The area of the existing slab in the
Office Space is approximately 8,500 sq ft. There is a full demising wall located between UDM
and the Office Space that does not contain doors, windows, or other openings between the spaces.
In addition, the heating, ventilating, and air conditioning (HVAC) systems for both sides are
separate. Therefore, UDM and the Office Space do not exchange air between the spaces and thus
the VIMS performance and effectiveness on each side of the demising wall are not expected to
affect operations on the opposite side of the wall.

The VIMS in the Office Space is an active sub-slab vapor depressurization system with electric
fans installed on the roof that discharge collected vapors above the building roofline. A brief
description of the installed VIMS components, inspection activities, and testing activities is
provided below.

2.1 VIMS Installation Inspections

Based upon periodic inspections completed during VIMS installation activities, the VIMS was
installed in general accordance with the DEQ-approved VIMP. VIMS details and specifications,
and VIMS as-built drawings which depict the VIMS layout and details are included in Attachment
C, a photographic log with pictures of the VIMS installation activities are provided in Attachment
D, and field sampling logs are included as Attachment E.

During installation of the VIMS, H&H conducted VIMS inspections in accordance with the DEQ-
approved VIMP from June 2021 to May 2023 including:

• inspection of suction points and suction trenches prior to concrete repair/replacement;
• inspection of suction points and trenches after installation and concrete had been replaced;
6
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
• inspection of above-grade riser duct piping;
• inspection of monitoring points and suction trench clean-outs;
• inspection of the electric fans; and
• inspection of the vacuum sensors and Sensaphone telemetric monitoring system.

The VIMS generally includes installation of suction points and suction trenches connected to 3-
inch diameter Schedule 40 (Sch 40) PVC risers that are installed from the slab to the building roof.
Pressure-Tech PT-16 electric fans are installed on the discharge end of the riser duct piping. In
addition, Senva P4 Series vacuum sensors are installed on the risers adjacent to the fans to monitor
vacuum levels in the riser. The vacuum readings are transmitted to the Sensaphone Sentinel to
monitor for proper function of the fan or determine if troubleshooting is required due to an
inoperable or malfunctioning fan.

As indicated in the VIMP, portions of the concrete slab were removed and replaced for the
installation of utilities and areas specific to the commercial tenants. For the concrete replacement
inside the existing building, approximately four inches of washed #57 stone gravel and either the
Stego Industries 15-mil Stego-Wrap Vapor Barrier (Stego-Wrap) or the 15-mil Raven
VaporBlock-15 Vapor Barrier, which are both ASTM Class A vapor barriers, were installed using
manufacturer specified tapes and mastic prior to installation of the new concrete slab sections.

Note, a slight change to the VIMP occurred during construction that included installation of an
alternative style monitoring point at some locations. Due to difficulty of the contractor to install
and seal the monitoring points with the floor clean-out covers in select areas as depicted in the
VIMP, several of the monitoring points were switched to Cox-Colvin Vapor Pin® style monitoring
points which are installed through the slab. The Vapor Pin monitoring points are a commonly
used and accepted method for monitoring points for existing slabs and thus are an equivalent
replacement and type of installed monitoring point are depicted in the as-built drawings. For the
Office Space, monitoring points MP-12, MP-13, and MP-15 are installed with Vapor Pins.

2.2 VIMS Influence Testing

On June 7, 2023 post-installation VIMS influence (pilot) testing was conducted at the Office Space
of the building after the concrete slab pours were completed to evaluate system sub-slab
communication with the installed electric fans operating. After inspection of the fans to verify
proper installation, differential pressure measurements were collected at the vacuum monitoring
points within the treatment area being tested using a Dwyer series 475 Mark III digital manometer
(capable of measuring to 0.001 inches of water column [in-WC] or 0.25 Pascals [Pa]) to establish
baseline conditions prior to turning on the electric fans. Following collection of baseline
differential pressure measurements, the electric fans were turned on and differential pressure
measurements were collected at each monitoring point and fan after approximately 30-minutes.
Permanent monitoring points (denoted by MP nomenclature) are shown on the as-built drawings
in Attachment B. A summary of the influence testing results is included in Table E-1 in
Attachment E.

The influence testing in the office space portion of the building indicated that sub-slab vacuum
measurements ranged from 0.075 in-WC to 0.617 in-WC at each monitoring point, with vacuum
influence greater than 4 Pa (0.016 in-WC) being maintained throughout the slab with the electric
fans operating. The vacuum measurements are notably greater than 0.016 in-WC which indicates
sufficient vacuum levels are present below the slab.

As a follow-up to the pilot test, an additional round of vacuum readings from the Office Space
were collected on August 2, 2023. The vacuums during this event ranged from 0.072 in-WC to
1.025 in-WC, which are similar to the vacuums recorded during the pilot test and are notably above
the recommended minimum of 0.016 in-WC.

Sensaphone Details
As indicated in the VIMP, a Sensaphone Sentinel telemetric monitoring system was installed to
provide notifications and an online interface to monitor the vacuum sensor data. The Sensaphone
is installed within the central portion of the UDM Food Hall (see Sheet VM-1) and is located
within a lockable box enclosure. The telemetric monitoring system will alert building maintenance
8
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
staff via email, text, and/or phone notifications if the fans fail to operate correctly based on a drop
in vacuum levels from the Senva sensors or if there is a loss of power to the system. Several
maintenance staff will be added to the alarm notifications and the Sensaphone is programmed to
send multiple notifications if the alarm is not addressed. H&H is currently preparing an operations
and maintenance (O&M) Plan for the building maintenance department to describe the VIMS
components and alarm notifications and actions.

Please note, in late July 2023, H&H observed that there may be an electrical issue with the
Sensaphone that transmits data from the three electric fans in the Office Space based on an alert
from the Sensaphone monitoring system. On August 2, 2023, H&H performed a Site visit to
further investigate and verify operation of the electric fans and sub-slab vacuum levels. The
observations indicated an electric transformer for the vacuum sensors that transmit data to the
Sensaphone device may not be working properly; therefore, the property owner has been notified
to conduct repairs on the transformer. Despite this electrical issue, based on the vacuum readings
collected on August 2, 2023 (see above), the VIMS electric fans are working properly, and
adequate vacuum is present below the slab of the Office Space.

3.0 Pre-Occupancy System Effectiveness Testing

Following installation of the VIMS and completion of interior construction activities, H&H
collected indoor air samples in accordance with the VIMP for laboratory analysis to evaluate
efficacy of the VIMS. Although not required by the VIMP, H&H also collected a concurrent
sub-slab soil gas (vapor) sample for comparison to the indoor air data. Comparison of the sub-
slab soil gas sample data to the indoor air sample data allows for evaluation of potential above slab
interference due to potential off-gassing of vapors from construction materials.

The sub-slab vapor and indoor air sampling activities were conducted in general accordance with
the DEQ-approved VIMP and the DEQ DWM Vapor Intrusion Guidance (Guidance) dated March
2018. During the analytical sampling, and in the several weeks leading up to the sampling, the
HVAC system in the office space and the electric VIMS fans were operating under normal
conditions.

3.1 Sub-Slab Soil Gas Sampling Methodology

On June 16, 2023, H&H collected one sub-slab vapor sample (MP-15) from monitoring point MP-
15 located in the eastern portion of the building and in an area of generally elevated sub-slab vapor
concentrations observed during previous assessment activities prior to renovation of the building.
The sub-slab vapor sample was collected one day after the indoor air sampling was completed (see
Section 3.3).

To collect the sub-slab vapor sample, Teflon® sample tubing secured to the vapor pin sampling
port and connected to an airflow regulator and laboratory-supplied batch-certified 1-liter stainless
steel Summa canister. The air flow regulator was preset by the laboratory to collect a soil gas
sample at a flow rate no greater than approximately 200 milliliters per minute.

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
10
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
the Summa canister. The air within the shroud was flooded with helium gas and concentrations
were measured with a calibrated helium detector. The helium concentration within the shroud was
maintained at approximately 11%. 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. 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 check indicate that short-circuiting at the monitoring point or
within the sampling train was not present at unacceptable levels. Sub-slab soil gas sample field
forms completed by sampling personnel are included in Attachment E.

Following a successful leak check, the air flow regulator was opened to allow collection of the
sub-slab soil gas samples. Vacuum in the Summa canister was monitored during the sampling
event to confirm adequate sample volume was collected at each monitoring point. Upon
completion of sample collection, the air flow regulator was closed to the Summa canister. The
canister was labeled with the sample identification, the beginning and ending times, the pressure
measurements, and the requested analysis. The canister was then placed in a laboratory-supplied
shipping container and delivered to Waypoint Analytical (Waypoint) under standard chain of
custody protocols for analysis of select VOCs by Environmental Protection Agency (EPA) Method
TO-15. The select list of compounds analyzed from the VIMP is included as Table F-1 in
Attachment F.

3.3 Indoor Air Sampling Methodology

On June 15, 2023, H&H collected two indoor air samples (IAS-OFF-1 and IAS-OFF-2) for
laboratory analysis within the office space portions of the building in accordance with the general
locations proposed in the VIMP. In addition, H&H collected an upwind exterior background air
sample (IAS-OFF-BKG) concurrently during indoor air sampling event to evaluate compound
concentrations in ambient outdoor air. These samples were collected the day prior to the sub-slab
vapor sampling described above. The indoor air sample and background air sample locations are
shown on Figure VM-1 (Attachment C).

11
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
One duplicate indoor air sample (IAS-OFF-DUP) was also collected for QA/QC purposes from
indoor air sampling location IAS-OFF-1. The duplicate indoor air sample was collected utilizing
a laboratory-supplied stainless-steel sampling “T” which allows for the simultaneous collection of
two indoor air samples from a single location.

Building conditions during indoor air sampling activities were consistent with anticipated
conditions during building occupancy and ingress and egress activities were minimized with the
HVAC system operational. The indoor air samples were collected using laboratory-supplied
individually-certified 6-liter stainless steel Summa sample canisters connected to in-line flow
controllers with a vacuum gauge. The background air sample was collected using a laboratory-
supplied batch-certified 6-liter stainless steel Summa sample canister connected to an in-line flow
controller with a vacuum gauge. The flow controllers were calibrated by the laboratory to allow
for sample collection over an approximate 8-hour period 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. For QA/QC purposes,
H&H personnel periodically monitored the sample canisters to 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 was maintained
within the canisters at the conclusion of the sampling event.

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 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 indoor pressure was the same as the exterior pressure on the
day of the indoor air sampling activities. A summary of the field measurement data collected at
the time of the indoor air sampling event is included in Attachment E.

Upon completion of the indoor air sampling event, the Summa canisters were properly labeled
with the sample identification, date, time, starting and ending vacuums, and requested analysis.

The canisters were then placed in a laboratory-supplied shipping container. The samples were
shipped under standard chain-of-custody protocols to Waypoint for analysis of select VOCs by
EPA Method TO-15.

3.3 Sub-Slab Vapor and Indoor Air Sampling Results

A tabular summary of the sub-slab vapor and indoor air sample analytical results is provided in
Table 1, and a copy of the laboratory analytical report with chain of custody record is provided as
Attachment F.

3.3.1 Sub-Slab Vapor Sampling Results

As the planned use of the building is for commercial (office) purposes, the sub-slab vapor sample
laboratory analytical results were compared to the DEQ DWM Non-Residential SGSLs dated
January 2023. Laboratory analytical results for the sub-slab vapor sample indicate the presence of
several petroleum-related compounds detected above laboratory method detection limits (MDLs).
None of the detected compounds were detected at concentrations above Non-Residential SGSLs.
Note, TCE, a main contaminant of concern from previous Brownfields assessment activities, was
not detected in the sub-slab vapor sample.

3.3.2 Indoor Air Sampling Results

The indoor air sample laboratory analytical results were compared to the DEQ DWM Non-
Residential IASLs dated January 2023. The indoor air sample analytical results indicate that
several compounds were detected at concentrations above laboratory MDLs in the indoor air
samples. Only one compound, naphthalene, was detected in one sample (IAS-OFF-DUP) at a
concentration (5.08 µg/m3) above the Non-Residential IASL of 0.36 µg/m3. Note, naphthalene
was not detected in the sub-slab vapor sample. Naphthalene is a common component of building
and construction materials including gasoline products and cleaners used during construction. The
field samplers notes that stainless steel cleaner and polish was observed inside of the Office Space
during the indoor air sampling. Review of the Safety Data Sheet (SDS) for this this product
13
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
indicates that it contains petroleum and “solvent naphtha”, which is a liquid form of naphthalene.
Therefore, the presence of this compound may be attributable to background indoor air sources
and the specific cleaners present inside the building.

No other compounds were detected at concentrations above the DEQ DWM Non-Residential
IASLs in the indoor air samples collected at the Site in June 2023. A low-level estimated value
(J-flag) of the chlorinated compound PCE (0.936 J µg/m3) was detected in the background sample
at a concentration well below the IASL, and PCE was not detected in any of the indoor air samples.
No TCE was detected in the indoor air samples or background sample.

3.4 Risk Evaluation
The DEQ DWM Vapor Intrusion screening levels are conservative and based on a total cancer risk
(TCR) for potential carcinogenic risks of 1 x 10-6 and a non-carcinogenic hazard quotient (HQ) of
0.2 for potential non-carcinogenic risks. The DEQ and EPA acceptable risk level for potential
carcinogenic risks is a cumulative lifetime incremental cancer risk (LICR) of 1 x 10-4 or less, and
the acceptable risk level for non-carcinogenic risks is a cumulative hazard index (HI) of 1 or less.
The HI is the sum of the HQs of detected compounds.

H&H utilized the DEQ Risk Calculator (January 2023) to further evaluate potential health risks
posed by sub-slab vapor and indoor air conditions. A “worst-case” non-residential use risk
scenario for the indoor air samples was calculated using the highest concentration of each detected
compound from any of the indoor air samples (and duplicate). The completed DEQ Risk
Calculators are included in Attachment G, and the risk calculator results are summarized in the
table below.

The worst-case non-residential use risk calculation indicates that the LICR was 1.5 x 10-5 and the
HI was 0.45 for the indoor air samples, both of which are within DEQ acceptable risk levels.
Therefore, the indoor air sample results and risk calculations indicate that concentrations of
compounds within the office spaces are not present at levels that would pose unacceptable risk to
the future commercial occupants of the building.
14
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/VIMS/2315 N. Davidson VIMS/Install - Office Space/24003_N. Davidson II_VIMS Install_Office Space.docx
H&H utilized the DEQ Risk Calculator (January 2023) to further evaluate potential vapor intrusion
risks. The sub-slab vapor risk calculations for the sample from MP-15 indicated a LICR of 3.2
x 10-8 and an HI of 0.00041, both of which are orders of magnitude below the unacceptable risk
levels. Therefore, the sub-slab soil vapor results and risk calculations indicate that concentrations
of compounds below the slab in this area are not present at levels that would pose unacceptable
risk to the future commercial occupants of the building.

While the risk levels for both the indoor air and sub-slab vapor samples are within acceptable
levels, the majority of the calculated indoor air risk is attributed to the concentration of naphthalene
detected in the indoor air duplicate sample. Naphthalene is a common component in building
materials and petroleum products, such as gasoline and stainless steel cleaner observed during the
sampling event. Further, naphthalene was not detected in the sub-slab vapor sample. Therefore,
the presence of naphthalene in the duplicate indoor air sample is likely attributable to off-gassing
of building materials or an above ground source, and it is not likely a result of vapor intrusion.

4.0 Summary and Conclusions

Installation of the active VIMS has been completed for the Office Space located within the eastern
portion of the building located at 2315 N. Davidson Street on the North Davidson II Brownfields
Property in Charlotte, North Carolina. The building is split into two sections, with the UDM Food
Hall encompassing the western portion of the building, and the Office Space on the eastern side of
the building. The two spaces within the building are separated by a demising wall and they have
separate HVAC systems so there is no direct air exchange between the spaces.

Based on the indoor air and sub-slab vapor sampling results conducted in June 2023 at the Site,
the results of cumulative risk calculations using the sub-slab vapor sample data and the indoor air
sample data indicate acceptable DEQ risk levels for the proposed commercial use of the building.
The Site contaminant of concern, TCE, was not detected in the sub-slab vapor or indoor air
samples.

Based on the inspections performed by H&H, the active VIMS was installed in general accordance
with the DEQ-approved VIMP, and the vacuum influence data indicates acceptable sub-slab
vacuum at each monitoring point with the electric fans operating. Further, based on the analytical
sampling data, there does not appear to be unacceptable risk from vapor intrusion of Site
contaminants to the future commercial occupants of the building.

5.0 System Monitoring Activities

VIMS Alarm System
In accordance with the DWM VI Guidance, the Sensaphone system was installed to monitor the
installed VIMS and provide notifications of potential issues with the system operation. The
Sensaphone system consists of a telemetric monitor (Sentinel) that will alert building maintenance
staff via email, text, and/or phone notifications if any of the fans fail to operate correctly (see
Section 2.0). Operating data for each fan is uploaded to a web interface that stores data and sends
electronic notifications of alarms to the proper parties. The Sensaphone is set-up with the online
interface and is connected to the internet within the UDM Food Hall.

The building management group will be the responsible party for receiving these notifications and
will be instructed to notify H&H of alerts or alarm activation if any of the fans fail or cease
operation. In addition, the building maintenance staff will perform inspections of the VIMS
components. The inspections will include accessible aboveground piping, monitoring points,
overall condition of the accessible and floor slab, and inspection of the electric fans and discharges.
H&H is currently preparing an O&M Plan for the building maintenance department to describe
the VIMS components and alarm notifications and actions.

Vacuum Monitoring & Analytical Sampling
In accordance with the VIMP, quarterly vacuum monitoring will be conducted after occupancy
and reported to DEQ after each event. After the first year of quarterly vacuum monitoring with
acceptable vacuum data, a request may be submitted to DEQ for approval to reduce the vacuum
monitoring frequency. In addition, post-occupancy indoor air analytical sampling events will be
conducted on a semi-annual basis after occupancy and each sampling event will be reported to
DEQ Brownfields. After the first year of analytical sampling and evaluation of the data, a request
may be submitted to DEQ for approval to reduce the frequency of the analytical sampling events
and the vacuum monitoring events. The reporting provisions, if warranted, as outlined in the DEQ
TCE Action Levels will be followed upon receipt of the analytical laboratory reports.

With both the UDM Food Hall and Office Space VIMS construction complete, the quarterly
vacuum monitoring and analytical sampling events are anticipated to be conducted for the entire
building during the same sampling events. Therefore, the next quarterly vacuum monitoring event
for the building is proposed for September 2023, with the first post-occupancy semi-annual
analytical sampling event proposed for December 2023 or January 2024, to align with indoor air
sampling to be performed during the heating season.

THIS VAPOR MITIGATION PLAN WAS USED FOR DIRECTION OF VIMS COMPONENT INSTALLATION ONLY AND WAS NOT INTENDED TO GUIDE CONSTRUCTION OF STRUCTURALCOMPONENTS NOT RELATED TO THE VIMS.2. NOT EVERY CONDITION OR ELEMENT COULD BE EXPLICITLY SHOWN ON THESE DRAWINGS; THEREFORE, THE CONTRACTOR USED INDUSTRY ACCEPTED STANDARD GOODPRACTICE FOR MISCELLANEOUS WORK NOT EXPLICITLY SHOWN.3. THE CONTRACTOR WAS INSTRUCTED TO USE MATERIALS OR PRODUCTS THAT DID NOT CONTAIN THE COMPOUNDS TETRACHLOROETHENE (PCE) OR TRICHLOROETHENE(TCE). THE CONSTRUCTION CONTRACTOR SUPPLIED THE DESIGN ENGINEER SAFETY DATA SHEETS (SDS) FOR ALL MATERIALS USED FOR CONSTRUCTION.4. CHANGES OR MODIFICATIONS TO THE SYSTEM DURING CONSTRUCTION WERE APPROVED BY THE DESIGN ENGINEER. AFTER COMPLETION AND CERTIFICATION OF THEVIMS BY NORTH CAROLINA DEPARTMENT OF ENVIRONMENTAL QUALITY (DEQ ) PROPOSED MODIFICATIONS OR CHANGES TO THE SYSTEM ARE TO BE PROVIDED TO THEDESIGN ENGINEER AND DEQ FOR APPROVAL.B) SUCTION TRENCHES AND SUCTION POINTS1. AT THE SUCTION TRENCHES, A 12" DEEP BY 12" WIDE TRENCH WAS EXCAVATED WITHIN THE EXISTING SOILS BELOW THE EXISTING CONCRETE SLAB AT LOCATIONSDEPICTED ON SHEET VM-1. THE TRENCH WAS FILLED WITH WASHED (CLEAN) #57 STONE GRAVEL, AND A 3" DIA SCH 40 PVC SLOTTED PIPE. A VAPOR BARRIER WASINSTALLED BETWEEN THE 57 STONE AND NEW CONCRETE. WHERE APPLICABLE, THE VAPOR BARRIER USED WAS 15-MIL STEGO INDUSTRIES,LLC STEGO WRAP VAPORINTRUSION BARRIER.2. VIMS PIPE CONSISTS OF 3" SCH 40 PVC. PVC PIPE JOINTS WERE CONNECTED USING PVC SOCKET COUPLINGS AND LOW-VOC PVC GLUE OR THREADED FITTINGS.3. SOILS USED TO BACKFILL AROUND SOLID SECTIONS OF PIPE WAS COMPACTED PRIOR TO COMPLETING THE TRENCH WITH CONCRETE. SOLID SECTIONS OF PIPE WERENOT TRAPPED AND SLOPED A MINIMUM OF 1% (18" PER FOOT) TO ALLOW FOR ACCUMULATED WATER TO GRAVITY DRAIN TO THE SUCTION POINT.4. NEW CONCRETE ON TOP OF THE SUCTION POINTS AND SUCTION TRENCHES IS A MINIMUM 6" THICK WITH REBAR AND WIRE MESH.C) RISER PIPES AND FANS1.VERTICAL PIPE RUNS WERE GENERALLY SUPPORTED AT LEAST EVERY 10 FEET AND AT EVERY PENETRATION THROUGH SLABS, CEILINGS, OR ROOF DECKS ANDINSTALLED APPLICABLE 2018 NORTH CAROLINA STATE PLUMBING CODES.2. MODIFICATIONS TO THE HORIZONTAL RUNS FOR ABOVE GRADE VENT PIPING WERE APPROVED BY THE DESIGN ENGINEER.

PressureTech High Suction Radon Fans

PressureTech is changing the game for the radon industry with the introduction of the most effective and energy efficient radon fan ever developed! For the first time ever, a residential radon fan is capable of achieving extraordinary levels of static pressure while operating quietly and efficiently. PressureTech will conquer radon problems under the most challenging conditions including clay soil, compacted sand, and even bedrock.
PressureTech has revolutionized the radon fan industry by utilizing DC motor technology which can achieve much higher air flow and suction than typical radon fans. Until PressureTech, radon fans have been made using outdated and inefficient AC motor technology. The PressureTech radon fan is capable to producing over 5 times more static pressure than the leading radon fans and can do so using a fraction of the electricity! At the heart of the PressureTech fan is an ultra-efficient, computer-controlled direct current motor
with integrated impeller system for years of trouble-free continuous operation.
One of the biggest advantages of PressureTech fans over traditional radon fans is the low voltage motor. In fact, the voltage is so low that most jurisdictions do not require an electrical license or permits to wire the fan!

IMPORTANT NOTICE: PressureTech PT Series Fans have low voltage DC motors and must be used
with the included power converter when connected to standard voltage (110-120V AC). Connecting
fan directly 110/120V power source without power converter will damage fan and void warranty.
See wiring instructions on last page of this manual.
PressureTech’s fans can be used for virtually any radon mitigation or vapor intrusion application, residential or commercial. The pressure adjustment dial allows you to adjust the flow of the system in conjunction with your diagnostic testing to achieve optimal
negative pressure below the slab. With suction capabilities exceeding 10-inches of
water column, there is no project that this fan can’t handle! PressureTech is excited to introduce the radon fan that will put an end to problem houses once and for all! So, don’t delay; try a PressureTech radon fan on your next installation and experience for yourself the future of the radon mitigation industry!
The extraordinary thing about the PressureTech fan is that you don’t have to wait until
you have a problem house to use it. Although it can handle those homes with difficult soil conditions, this fan is quiet and energy-efficient enough to use for your everyday installations.
Using the PressureTech product gives the mitigator a clear advantage over their
competitors. Not only does it have suction capabilities far beyond anything else on the
market, but the motor actually runs on a low voltage current. What this means is that many of the expenses associated with the installation are eliminated. For example, most municipalities do not require a licensed electrician for low voltage wiring. Many of the permits and subsequent inspection fees are not necessary when using this fan. And,
quite frankly, the fact that it is low voltage completely eliminates the risk of electrical
hazards that are associated with wiring higher voltages.
There are a lot of radon contractors out there who are walking a fine line by doing their own wiring of 110volt fans. In most states, this is simply illegal and puts both the homeowner and the installer at risk. This type of liability nightmare can be now be
avoided thanks to the low voltage technology PressureTech is bringing to the table.
The radon industry simply has never seen a product like this. There’s just nothing else like it on Earth! This product could change the game and make those “nightmare” mitigation jobs a thing of the past.
Fan Model Volts Watts Maximum Pressure Maximum Airflow
PressureTech PT8 24V (includes 110V converter) 58-80 8.6″ WC 50 CFM
PressureTech PT16 36V (includes 110V converter) 110-170 17.4″ WC 67 CFM
PressureTech P25 48V (includes 110V converter) 255-298 25.2″ WC 82 CFM

PressureTech PT8
With PressureTech’s introduction of the PT8 Radon Fan, the radon industry has finally turned the
corner into modern-day technology! The PT8 was designed with two things in mind: unmatched
performance and unmatched energy efficiency. Thanks to recent developments in DC motor
technology, PressureTech has been able to create an in-line fan that is capable of achieving OVER
8 INCHES OF SUCTION while using only 60 watts of power! The motor is also low voltage, so wiring
the fan doesn’t require a licensed electrician or permit in most jurisdictions. The PT8 is ultra-quiet,
efficient, and extremely effective at more than doubling the pressure field extension (PFE) you
achieve below the slab, compared to the other “high suction” radon fans that are on the market.

PressureTech PT16 & PT25
PressureTech has taken “high suction” to another level by introducing the PT16 and PT25 radon
mitigation / vapor intrusion fans. With static pressure capabilities up to 25 inches of water column,
this compact in-line fan outperforms loud, bulky box fans that are commonly used for commercial
radon mitigation and vapor intrusion projects. The PT Series has many advantages over other fans
thanks to the revolutionary DC motor technology that PressureTech has introduced. Direct Current
(DC) motors are capable of much higher speeds and run more efficiently than traditional fan motors.
The result is higher suction, higher airflow, and lower electrical consumption. By using less
electricity, these fans save your clients money in operating costs and will outlast traditional motors
that tend to burn out much sooner due to excessive heat. Because of lower electrical consumption
than Alternating Current (AC) motors, DC motors run at much lower temperatures which extends the
running life up to 5 times longer.
PressureTech PT Series Radon / Vapor Fan Installation and Operating Instructions

Installation Instructions

1. After interior portion of radon system piping is installed and routed to the outdoor
wall of the building, the radon fan must be installed in-line with the piping. NOTE:
Always install the fan in an upright position to avoid moisture accumulation in the
housing.
2. Using an appropriate rubber connector or pipe reducer coupling, securely
connect the inlet portion of the fan to the vertical riser of the outdoor piping.
Tighten the metal clamps on the both side of the connector to ensure that fan is
adequately secured to the pipe.
3. Build the exhaust stack which will be installed on the outlet of the fan.
4. Attach the exhaust stack to the outlet of the fan using an appropriate rubber
connector or pipe reducer coupling. Attach the exhaust stack to the exterior of
the building so it is securely held by pipe clamps to avoid excess weight/stress
being applied to the fan.
5. Install the power converter in appropriate location. Do not connect power to the
power converter until the fan is completely wired.
6. Remove the cap from the fan electrical box.
7. Connect the wires from the power converter to the wire terminals in fan electrical
box using appropriate connectors. NOTE: Outdoor wiring should be enclosed in
outdoor rated conduit.
8. Once all wire connections are secure in the fan electrical box, connect the power
converter to the power source and check to make sure the fan is running.
9. Once confirmed that the fan is running, check all connections and electrical cover
to ensure that the installation is secure.
10. Activation and troubleshooting: If fan is not running, check any disconnect
switches to make sure they are in the ON position. If the fan does not activate
from a power switch, check the wiring inside of the fan electrical box to make
sure no connections were broken or wired improperly. Also, check the circuit
breaker for the outlet that system is plugged into to confirm that it hasn’t tripped.

Operating Instructions

PressureTech PT Series radon / vapor fans are intended to run continuously to
maintain healthy air within the building. Once the radon system is installed and fan
is activated, power should never be disconnected except to service or replace the
fan.

Power Converter

The PressureTech PT Series radon / vapor fans have low voltage DC motors, so a
power converter must be installed to convert the 110V power source to a low voltage
current. The power converter can be wired anywhere between the fan and power
source and is rated for both indoor and outdoor applications. Simply connect the
positive (red) and negative (black) DC wires to the fan. Then, connect the hot
(black), neutral (white) and ground (green) wires to your 110V power source or
utilize flexible plugged cord to plug into an outlet when located within 6-feet of the
power supply location.

** - 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.

SECTION 4: FIRST AID MEASURES
Description of First Aid Measures
General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label if possible).
Inhalation: If inhaled, remove to fresh air and keep at rest in a position comfortable for breathing. Seek medical attention
immediately.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with mild soap and water. Obtain medical attention if irritation
develops or persists. Wash contaminated clothing before reuse.
Eye Contact: Do not rub. Rinse eyes thoroughly with water for at least 15 minutes, including under lids, to remove all particles. Seek
medical attention for abrasions.
Ingestion: Rinse mouth. Do not induce vomiting. Immediately call a POISON CENTER or doctor/physician.
Most Important Symptoms and Effects Both Acute and Delayed
General: Causes damage to organs. May cause cancer.
Inhalation: The three types of silicosis include: 1) Simple chronic silicosis which results from long-term exposure (more than 20
years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirable
crystalline silica form in the lungs and chest lymph nodes. This disease may feature breathlessness and may resemble chronic
obstructive pulmonary disease (COPD); 2) Accelerated silicosis occurs after exposure to larger amounts of respirable crystalline
silica over a shorter period of time (5-15 years); 3) Acute silicosis results from short-term exposure to very large amounts of
respirable crystalline silica. The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood
oxygen levels. Inflammation, scarring, and symptoms progress faster in accelerated silicosis than in simple silicosis. Progressive
massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive
fibrosis results from severe scarring and leads to the destruction of normal lung structures. Some studies show that exposure to
respirable crystalline silica (without silicosis) or that the disease silicosis may be associated with the increased incidence of several
autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and
diseases affecting the kidneys. Silicosis increases the risk of tuberculosis. Some studies show an increased incidence of chronic
kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica. Irritating to mouth, nose, throat, and
lungs, may cause difficulty in breathing.
Skin Contact: Aggregates may cause dry skin, abrasions, discomfort, and irritation.
Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of gypsum
can cause moderate eye irritation, redness, and abrasions. Eye exposures require immediate first aid.
Ingestion: Ingestion of large quantities can cause an obstruction causing pain and distress in the digestive tract.
Chronic Symptoms: If dust is generated, repeated exposure through inhalation may cause cancer or lung disease. Causes damage to
organs.
Indication of Any Immediate Medical Attention and Special Treatment Needed
If exposed or concerned, get medical advice and attention.

Methods and Material for Containment and Cleaning Up
For Containment: Place spilled material into a container. Avoid actions that cause dust to become airborne. Avoid inhalation of dust.
Wear appropriate protective equipment as described in Section 8. Do not wash gypsum down sewage and drainage systems or into
bodies of water (e.g. streams).
Methods for Cleaning Up: Avoid actions that cause dust to become airborne during clean-up such as dry sweeping or using
compressed air. Use HEPA vacuum or thoroughly wet with water to clean-up dust. Use PPE described in Section 8. Contact
competent authorities after a spill.
Reference to Other Sections
See heading 8, Exposure Controls and Personal Protection. Concerning disposal elimination after cleaning, see item 13.
SECTION 7: HANDLING AND STORAGE
Precautions for Safe Handling
Additional Hazards When Processed: Cutting, crushing or grinding gypsum or other crystalline silica-bearing materials will release
respirable crystalline silica. Use all appropriate measures of dust control or suppression, and Personal Protective Equipment (PPE)
described in Section 8 below.;Do not handle until all safety precautions have been read and understood.
Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands and other exposed areas
with mild soap and water before eating, drinking, or smoking and again when leaving work. Wash contaminated clothing before
reuse.
Conditions for Safe Storage, Including Any Incompatibilities
Storage Conditions: Handle with care and use appropriate control measures. Keep bulk gypsum dry until used.
Engulfment hazard. To prevent burial or suffocation, do not enter a confined space, such as a silo, bin, bulk truck, or other storage
container or vessel that stores or contains gypsum. Gypsum can build up or adhere to the walls of a confined space. The gypsum
can release, collapse or fall unexpectedly. Do not stand on stockpiles of gypsum, they may be unstable. Use engineering controls
(e.g. wetting stockpiles) to prevent windblown dust from stockpiles, which may cause the hazards described in Section 3.
Incompatible Materials: Gypsum is incompatible with acids. Gypsum contains silicates which may react with powerful oxidizers such
as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride.
Specific End Use(s): Gypsum is used in the manufacturing of drywall, drywall compounds, and cement, concrete and concrete

* * * Section 4 - First Aid Measures * * *
First Aid: Eyes
In case of contact with eyes, immediately flush with clean, low-pressure water for at least 15 min. Hold eyelids
open to ensure adequate flushing. Seek medical attention.
First Aid: Skin
Remove contaminated clothing. Wash contaminated areas thoroughly with soap and water or with waterless hand
cleanser. Obtain medical attention if irritation or redness develops.
First Aid: Ingestion
DO NOT INDUCE VOMITING. Do not give liquids. Obtain immediate medical attention. If spontaneous vomiting
occurs, lean victim forward to reduce the risk of aspiration. Monitor for breathing difficulties. Small amounts of
material which enter the mouth should be rinsed out until the taste is dissipated.
First Aid: Inhalation
Remove person to fresh air. If person is not breathing, provide artificial respiration. If necessary, provide
additional oxygen once breathing is restored if trained to do so. Seek medical attention immediately.
* * * Section 5 - Fire Fighting Measures * * *
General Fire Hazards
See Section 9 for Flammability Properties.
Vapors may be ignited rapidly when exposed to heat, spark, open flame or other source of ignition. Flowing
product may be ignited by self-generated static electricity. When mixed with air and exposed to an ignition source,
flammable vapors can burn in the open or explode in confined spaces. Being heavier than air, vapors may travel
long distances to an ignition source and flash back. Runoff to sewer may cause fire or explosion hazard.
Hazardous Combustion Products
Carbon monoxide, carbon dioxide and non-combusted hydrocarbons (smoke). Contact with nitric and sulfuric
acids will form nitrocresols that can decompose violently.
Extinguishing Media
SMALL FIRES: Any extinguisher suitable for Class B fires, dry chemical, CO2, water spray, fire fighting foam, or
gaseous extinguishing agent.
LARGE FIRES: Water spray, fog or fire fighting foam. Water may be ineffective for fighting the fire, but may be
used to cool fire-exposed containers.
Firefighting foam suitable for polar solvents is recommended for fuel with greater than 10% oxygenate
concentration.
Unsuitable Extinguishing Media
None

Fire Fighting Equipment/Instructions
Small fires in the incipient (beginning) stage may typically be extinguished using handheld portable fire
extinguishers and other fire fighting equipment. Firefighting activities that may result in potential exposure to high
heat, smoke or toxic by-products of combustion should require NIOSH/MSHA- approved pressure-demand self-
contained breathing apparatus with full facepiece and full protective clothing. Isolate area around container
involved in fire. Cool tanks, shells, and containers exposed to fire and excessive heat with water. For massive
fires the use of unmanned hose holders or monitor nozzles may be advantageous to further minimize personnel
exposure. Major fires may require withdrawal, allowing the tank to burn. Large storage tank fires typically require
specially trained personnel and equipment to extinguish the fire, often including the need for properly applied fire
fighting foam.
* * * Section 6 - Accidental Release Measures * * *
Recovery and Neutralization
Carefully contain and stop the source of the spill, if safe to do so.
Materials and Methods for Clean-Up
Take up with sand or other oil absorbing materials. Carefully shovel, scoop or sweep up into a waste container for
reclamation or disposal. Caution, flammable vapors may accumulate in closed containers.
Emergency Measures
Evacuate nonessential personnel and remove or secure all ignition sources. Consider wind direction; stay upwind
and uphill, if possible. Evaluate the direction of product travel, diking, sewers, etc. to confirm spill areas. Spills
may infiltrate subsurface soil and groundwater; professional assistance may be necessary to determine the extent
of subsurface impact.
Personal Precautions and Protective Equipment
Response and clean-up crews must be properly trained and must utilize proper protective equipment (see Section
8).
Environmental Precautions
Protect bodies of water by diking, absorbents, or absorbent boom, if possible. Do not flush down sewer or
drainage systems, unless system is designed and permitted to handle such material. The use of fire fighting foam
may be useful in certain situations to reduce vapors. The proper use of water spray may effectively disperse
product vapors or the liquid itself, preventing contact with ignition sources or areas/equipment that require
protection.
Prevention of Secondary Hazards
None
* * * Section 7 - Handling and Storage * * *
Handling Procedures
USE ONLY AS A MOTOR FUEL.
DO NOT SIPHON BY MOUTH
Handle as a flammable liquid. Keep away from heat, sparks, and open flame! Electrical equipment should be
approved for classified area. Bond and ground containers during product transfer to reduce the possibility of
static-initiated fire or explosion.

IARC has determined that gasoline and gasoline exhaust are possibly carcinogenic in humans. Inhalation
exposure to completely vaporized unleaded gasoline caused kidney cancers in male rats and liver tumors in
female mice. The U.S. EPA has determined that the male kidney tumors are species-specific and are irrelevant
for human health risk assessment. The significance of the tumors seen in female mice is not known. Exposure to
light hydrocarbons in the same boiling range as this product has been associated in animal studies with effects to
the central and peripheral nervous systems, liver, and kidneys. The significance of these animal models to predict
similar human response to gasoline is uncertain.
This product contains benzene. Human health studies indicate that prolonged and/or repeated overexposure to
benzene may cause damage to the blood-forming system (particularly bone marrow), and serious blood disorders
such as aplastic anemia and leukemia. Benzene is listed as a human carcinogen by the NTP, IARC, OSHA and
ACGIH.
