VIMS Construction Completion Report – Revision 1 Commercial/Office Building 2100 S. Tryon Street Brownfields Site Charlotte, North Carolina Brownfields Project ID: 22054-18-060
H&H Job No. VBG.013
1.0 Introduction

On behalf of VV 2100 Development, LLC c/o Vision Ventures (Vision Ventures), Hart &
Hickman, PC (H&H) has prepared this revised Construction Completion Report summarizing
vapor intrusion mitigation system (VIMS) inspection, pre-occupancy testing, and sampling
activities conducted at the 2100 S. Tryon Street Brownfields property located in Charlotte,
Mecklenburg County, North Carolina (Site). The Site is in the North Carolina Department of
Environmental Quality (DEQ) Brownfields Program (Brownfields Project No. 22054-18-060).
The northeastern portion of the Site is being developed for commercial office use by Vision
Ventures and includes a 4-story commercial office building. In addition, the site plans include
construction of a retail building located in the southern portion of the Site. The retail building has
been constructed with a VIMS with components similar to those installed in the 4-story
commercial building (gravel, vent piping, and vapor barrier). H&H completed inspections of
VIMS components installed in each of the Buildings. However, the retail building in the southern
portion of the Site in is not currently included in the existing Brownfields Vapor Intrusion
Mitigation Plan (VIMP). On April 23, 2020, DEQ provided comments on the VIMS Construction
Completion Report dated March 12, 2020. Responses to the DEQ comments are included herein
this revised report.

At this time, the buildings recently constructed at the Brownfields Site will be used for commercial
purposes only, as indicated in the Brownfields plat. However, H&H understands that the Vision
Ventures (the Prospective Developer or PD) may elect to develop residential structures on the
Brownfields Site in the future. In this case, the PD understands that additional vapor assessment
and/or submittal of an updated VIMP to the DEQ Brownfields Program will likely be required. A
Site Location Map is included as Figure 1 and a Site Development Plan depicting the locations of
the office building and retail building on the Site is included as Figure 2.

\\hhfs01\MasterFiles\AAA-Master Projects\Vision Brokerage- VBG\VBG-013 2100 S. Tryon Street\Brownfields\VMP\Construction Completion Report\Rev 1\22054_VBG-013_VIMS CCR rev 1_050720.docx
The office building located in the northeastern portion of the Site consists of four floors. The first
floor (ground floor) consists of a common area, located in the central portion of the building, and
two pour-back areas (eastern pour-back area and western pour-back area), located on the east and
west sides of the common area. The pour-back areas consist of commercial spaces that will be
upfitted at a later date once a tenant leases the space. The common area and pour-back areas are
separated by walls and internal doors along with separate heating, venting, and air conditioning
(HVAC) systems. The upper floors (Floors 2 through 4) of the office building consist of office
spaces with elevator shafts and stairwells located in the central portion of the building.

H&H conducted VIMS inspection and pre-occupancy testing activities in the common area and
pour-back areas of the office building in accordance with the Vapor Intrusion Mitigation Plan -
Revision 1 dated June 9, 2019 and approved by the DEQ Brownfields Program on June 11, 2019.
The VIMP required installation of a VIMS underneath the office building, but the retail building
is not required to contain a VIMS. As specified in the VIMP and discussed above, a permanent
soil-gas point will be installed adjacent to the retail building during construction of the retail
building, and soil-gas sampling will be conducted at this location in accordance with the VIMP.
The results of the soil-gas point installation and soil-gas sampling will be reported to DEQ under
a separate submittal after these activities are complete.

The VIMS has been installed throughout the office building including the common area and the
pour-back areas. As further described in Section 2, the pour-back areas currently do not contain a
concrete slab, but the VIMS sub-slab vent piping network and vapor barrier have been installed
within these areas. Based on the results of the inspection, testing, and sampling activities, H&H
requests that the DEQ Brownfields Program acknowledge compliance with a land use restriction
(LUR) during preparation of the pending Notice of Brownfields Property for the first-floor
common area and upper floors of the office building. Because the pour-back areas have not been
upfitted at the time of this report, a separate VIMS Construction Completion Report will be
submitted to DEQ upon tenant upfit.

A summary of the VIMS installation inspection, pre-occupancy testing, and sampling activities is
provided in the following sections and further detail regarding the pour-back areas is presented in

2.0 Pour-Back Areas

The VIMS has been installed in the eastern pour-back area and western pour-back area in
accordance with approved-VIMP which included sub-slab vent piping connected to the risers and
fans and the specified vapor barrier (see Section 3.0). Even though a concrete floor has not been
poured in the pour-back areas, the vapor barrier is installed as a continuous layer throughout these
areas. Influence testing has been completed with acceptable results from below the installed vapor
barrier (see Section 3.2), and sub-slab analytical samples have been collected from below the vapor
barrier in the pour-back areas (see Section 3.4).

Prior to upfit of the pour-back areas, these areas will be physically separated and access secured
from tenants occupying the common area of the building. The current tenants and other building
occupants will not have access to these areas because interior doors leading to the pour-back areas
will be locked. No construction or other work activities are proposed to occur that could affect or
damage the vapor barrier in the pour-back areas until full upfit activities commence. The common
area and the pour-back areas will be served by separate HVAC systems and do not exchange air
with each other. HVAC systems have not yet been installed in the pour-back areas and will not be
installed until upfit occurs. The stairwells and elevators that could allow air exchange between the
ground floor and upper floors (Floors 2 through 4) are connected to the common area, and not to
the pour-back areas, which will prevent air exchange from the pour-back areas with the upper
floors. The combination of the installed VIMS in the pour-back areas and the physical separation
(including HVAC separation) with the common areas, will prevent sub-surface vapor intrusion
from the pour-back areas into the occupied portions of the building.

Upon upfit of the pour-back areas, sub-surface utilities may be installed by the tenants which would
require removal of select minor portions of the current vapor barrier and re-installation of the vapor
barrier. During upfit construction activities, the pour-back areas will be accessed directly from
exterior doors to prevent building occupants from entering the areas during construction. VIMS
components in the pour-back areas will be re-inspected by a North Carolina licensed Professional
Engineer (PE) or under the direction of a PE, during future upfit activities. While upfit activities
are not expected to impact the riser pipes or the fans, the inspections will include the same
inspections as described in Section 3.1 to ensure full system functionality after the upfit occurs.

After the vapor barrier inspection, a concrete slab will be installed in the pour-back areas. Once
the upfit activities are complete, a separate VIMS Construction Completion Report for the pour-
back areas will be submitted to DEQ.

3.0 VIMS Inspections, Testing, and Sampling
In accordance with the DEQ-approved VIMP, the VIMS under the office building is comprised of
a passive vapor extraction system utilizing a perforated vent pipe system and Empire Model
TV04SS wind driven ventilator fans coupled with the Stego Industries, LLC, Drago-Wrap® 20-
mil vapor barrier (Drago-Wrap) installed below the ground floor concrete slab of each building
section. The ground floor foundation of each building section contains slab-on-grade construction
with load-bearing columns.

During construction activities, H&H conducted VIMS inspections, pre-occupancy testing, and
sub-slab analytical sampling activities which are summarized in the following sections.
3.1 VIMS Inspections
Between October 3 and December 5, 2019, H&H conducted VIMS inspections of the common
area and pour-back areas during the following four stages of construction:

1. after completion of the sub-slab piping and gravel layout (Inspection 1);
2. after placement of the Drago-Wrap vapor barrier on top of the piping layout and gravel
layer (Inspection 2);
3. after installation of above-grade riser piping within the buildings (Inspection 3); and
4. after installation of the passive ventilator fans (Inspection 4).

During H&H’s inspections of the VIMS, H&H conducted two follow-up inspections of the
common area, and one follow-up inspection of the pour-back areas due to the following:

Common Area
1) During an inspection (Inspection 1) conducted on October 3, 2019, H&H noted that the
horizontal solid sections of sub-slab piping did not have the correct pitch to drain water.
H&H conducted a follow-up inspection on October 11, 2019 and confirmed that the riser
pitch had been corrected and that the sub-slab piping had been properly installed.

2) During an inspection (Inspection 2) conducted on October 9, 2019, H&H noted that the
vapor barrier was not sealed to the concrete footing in accordance with Detail 3 of the
VMP. H&H conducted a follow-up inspection of the vapor barrier on October 11, 2019
and confirmed that the vapor barrier was properly sealed. Note, select sections of vapor
barrier were left unsealed to allow inspection of the sub-slab piping during the October 11,
2019 inspection. The sections of vapor barrier overlying the re-inspected sub-slab piping
were repaired that same day while H&H was on Site.

Pour-Back Areas
1) During an inspection (Inspection 1) conducted on October 23, 2019, H&H noted that
temporary monitoring points TMP-1 and TMP-3 did not have the correct pitch to drain
water and TMP-3 was missing the vent screen specified in Detail 4 of the VMP. H&H
conducted a follow-up inspection on October 23, 2019 and confirmed that the monitoring
points had been repaired.

After completion of inspection and follow-up inspection activities, H&H concluded that the VIMS
within the common area and pour-back areas were properly installed by the contractor and were
equipped with turbine ventilator mitigation fans in accordance with the DEQ-approved VIMP.
VIMS Inspection Logs documenting inspection of the VMS are included in Appendix C.

3.2 Pilot Influence Testing

On December 5, 2019, H&H conducted “pilot” influence testing on the entire vent network
installed below the office building to verify VIMS functionality. The VIMS network was
constructed to connect the sub-slab annular space between the common area and pour-back areas.
Therefore, influence testing was conducted simultaneously on the VIMS below the entire ground
floor, including the below the concrete slab in the common areas and the below the continuous
vapor barrier in the pour-back areas.

During influence testing, H&H utilized temporary vapor extraction fans which were attached to
the vent pipe network from the roof of the building. The fans used for the testing included
RadonAway RP-265 and Festa AMG Legend electric fans. The fans utilized for the pilot test are

\\hhfs01\MasterFiles\AAA-Master Projects\Vision Brokerage- VBG\VBG-013 2100 S. Tryon Street\Brownfields\VMP\Construction Completion Report\Rev 1\22054_VBG-013_VIMS CCR rev 1_050720.docx
standard radon style fans that would likely be used if the VIMS was required to be converted from
a passive system to an active system. Furthermore, using temporary fans on the roof of the building
rather than the ground floor demonstrates anticipated sub-slab depressurization conditions in a
scenario where the system was an active system with electric radon fans installed on the roof.
Therefore, the vacuum readings were not recorded at the fan location during influence testing.
Vacuum measurements were collected at each monitoring point prior to activating the temporary
fans to establish baseline conditions. After the temporary fans were activated, 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]) was then connected to each pressure measuring port via Teflon tubing to record
differential pressures. H&H collected vacuum measurements at each monitoring point in the office
building over 15-minute time intervals.

Vacuum measurements recorded at the monitoring points during influence testing ranged from 4.5
Pa to 25.6 Pa, including measurements from below the vapor barrier in the pour-back areas.
Results of the influence testing indicate that adequate communication is present between the sub-
slab annular space and the riser/fans and adequate vacuum levels can be achieved throughout the
sub-slab annular space of the entire building footprint if active mitigation is necessary in the future.
The results also indicate the vapor barrier in the pour-back areas is properly sealed without an
overlying concrete slab. The Sub-Slab VIMS Pilot Test field logs summarizing vacuum and flow
measurements collected at each vapor extraction point location and differential pressure
measurements collected at each monitoring point during the testing are provided in Appendix C.

Following successful influence testing results, the temporary fans were replaced with the specified
Empire passive ventilator fans. The temporary monitoring points in the pour-back areas will
remain in place until upfit of these areas occur. Future construction plans for the upfit of the pour-
back areas may dictate the need for minor adjustments to temporary monitoring point locations.
The temporary monitoring points will be made permanent during upfit activities and if the final
locations of the monitoring points are moved or modified, DEQ will be notified of any such
modifications. The final monitoring point details will be reported to DEQ in the separate VIMS
Construction Completion report for the pour-back areas.

3.3 Sub-Slab Vapor Sampling Procedure
After completion of the VIMS components including installation of the turbine ventilator fans,
H&H collected sub-slab vapor samples from below the ground floor of the office building. As
required by the VIMP, a total of five (5) parent samples were collected from these building
sections. The sub-slab samples are identified with an “SS” designation along with the monitoring
point identification. One (1) duplicate sample was collected during each sampling event (two [2]
duplicates total) for quality assurance / quality control (QA/QC) purposes. The sub-slab vapor
samples were collected approximately two months after the installation of the concrete slab or
vapor barrier (pour-back areas) and several weeks after VIMS influence testing to provide
representative building conditions during sample collection.

In accordance with the VIMP, two (2) sub-slab samples were collected from the two permanent
monitoring points (MP-1 and MP-3) located in the common area to provide representative data of
sub-surface conditions (Sheet VM-1). In the pour-back areas, one (1) sub-slab sample was
collected from a monitoring point in the western pour-back area (MP-4), and two (2) sub-slab
samples were collected from two monitoring points in the eastern pour-back area (TMP-1 and
TMP-3) (Appendix A). Despite having proper vapor barrier seals in the pour-back areas (as
demonstrated during the influence testing), the intake for the sampled monitoring points in this
area were also located approximately 7 ft from penetrations or seams as an extra precaution to
prevent potential ambient air short-circuiting. The volume of air in the sub-surface gravel for the
1-liter sample along with the purge volume is limited to approximately a 3-square foot area of sub-
slab annular space (approximately 1 cubic foot of volume), and thus would not be influenced by
potential short-circuiting from the seams or penetrations located 7 ft from the intake screen.

The sub-slab samples were collected from vacuum monitoring points that are screened within the
gravel layer beneath the vapor barrier. Recommended procedures presented in the DEQ Division
of Waste Management (DWM) Vapor Intrusion (VI) Guidance were used to collect the samples
which included the following:

• A temporary expandable plug was placed within the sample port into the point to create an
air-tight seal.

\\hhfs01\MasterFiles\AAA-Master Projects\Vision Brokerage- VBG\VBG-013 2100 S. Tryon Street\Brownfields\VMP\Construction Completion Report\Rev 1\22054_VBG-013_VIMS CCR rev 1_050720.docx
• Prior to sample collection, H&H conducted a leak test at each vacuum measuring point by
placing a shroud around the point and entire sampling train including the Summa canister,
regulator, and sampling apparatus.
• The air within the shroud was saturated with helium gas. Soil gas was then purged from
the sampling point with an air pump (Gilian GilAir-3) into a Tedlar® bag.
• A helium gas detector was used to measure helium concentrations in the shroud and bag.

The leak test was considered successful if the helium concentration measured in the soil gas purged
from the sampling point was less than 10% of the concentration measured in the shroud.
Successful completion of this leak check ensured that short-circuiting at the sample point did not
occur and that the data collected accurately represented soil gas concentrations. Sub-Slab Vapor
Field Forms are included in Appendix C.

Following a successful leak check, the sub-slab vapor samples were collected into batch-certified
1-liter stainless steel Summa canisters connected to an airflow regulator preset by the laboratory
to collect vapor at an approximate flow rate of 0.1 L/min for a 10-min sampling period. In
accordance with the VIMP, the samples were submitted for analysis of select volatile organic
compounds (VOCs) by EPA Method TO-15 to Con-Test Analytical Laboratory, a nationally
accredited laboratory. The laboratory analytical results were compared to the DEQ DWM Non-
Residential Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs) dated February 2018. A
tabular summary of the post VIMS construction sub-slab vapor analytical results is presented in
Table 1. The laboratory analytical reports with chain of custody records are provided as Appendix
D.

To further evaluate the detected VOCs, H&H input the concentrations of the compounds detected
in each sub-slab vapor sample into the DEQ Risk Calculator (December 2019 Version) for a non-
residential use scenario. A summary of the calculated Lifetime Incremental Cancer Risks (LICRs)
and Hazard Index (HI) values are provided in Table 1 and copies of the risk calculator summary
pages are provided in Appendix E. Note, as a conservative measure, the higher of the detected
concentration for each constituent in the parent and duplicate samples were used in the risk
calculator.

\\hhfs01\MasterFiles\AAA-Master Projects\Vision Brokerage- VBG\VBG-013 2100 S. Tryon Street\Brownfields\VMP\Construction Completion Report\Rev 1\22054_VBG-013_VIMS CCR rev 1_050720.docx
3.4 Sub-Slab Vapor Sampling Results
The results of analysis indicate that several VOCs were detected at low concentrations above
laboratory method detection limits (MDLs) in the samples from each of the monitoring points. No
compounds were detected at concentrations above Non-Residential SGSLs in any of the samples.

The risk calculators indicated the calculated LICR for Sample SS-MP-1 was 0.0, which indicates
that no VOC compounds with carcinogenic risk were detected in this sample. The LICRs from
each of the remaining four sub-slab vapor samples ranged from 1.8 x 10-11 to 4.4 x 10-8, which are
notably below the acceptable risk level of 1 x 10-4. The calculated HI for each of the five sub-slab
vapor samples ranged from 0.0021 to 0.019, which are notably below the acceptable threshold
level of 1. The calculated LICRs and HI for each of the samples and individual buildings are
summarized in Table 1.

Based upon the risk calculations, VOC vapor concentrations detected below the footprint of the
office building do not pose an unacceptable risk to future occupants of the building and do not
indicate a potential vapor intrusion concern. Therefore, the collection of indoor air analytical
samples is not warranted.

\\hhfs01\MasterFiles\AAA-Master Projects\Vision Brokerage- VBG\VBG-013 2100 S. Tryon Street\Brownfields\VMP\Construction Completion Report\Rev 1\22054_VBG-013_VIMS CCR rev 1_050720.docx
4.0 Summary and Recommendations

VIMS installation activities have been completed for the office building located at the 2100 S.
Tryon Street Brownfields Property being developed by Vision Ventures. Based on the results of
our recent VIMS inspections, testing, and sampling activities, H&H certifies that the VIMS
associated with office building have been properly installed per the approved VIMP. The VIMS
vent pipe network is interconnected underneath the entire building and a continuous vapor barrier
has been installed across the entire ground floor. The ground floor of the office building contains
a common area that has a completed concrete slab and two pour-back areas that do not contain a
concrete slab.

Influence testing across the entire ground floor area, including the common area and pour-back
areas indicated adequate vacuum influence to depressurize the sub-slab annular space can be
achieved under current conditions. In addition, based upon the sub-slab vapor sampling results,
the VOC vapor concentrations detected in the sub-slab annular space below the common area and
pour-back areas do not pose an unacceptable risk to future occupants of the building and do not
warrant follow-up indoor air analytical sampling.

Even though the influence testing was adequate and the analytical results below the pour-back
areas do not indicate unacceptable risk, because the pour-back areas will be upfitted at a later date,
additional VIMS inspections (Section 2.0) will be conducted in these areas during upfit
construction activities. Therefore, H&H requests that the DEQ Brownfields Program grant
compliance with the vapor mitigation to be included in the pending LUR for the common areas
and the upper floors of the office building. A separate VIMS Construction Completion Report for
the pour-back areas will be submitted to DEQ once the upfit activities are near complete.

Additionally, sub-slab vapor samples will be collected from select monitoring points in the pour-
back areas and/or the common area on an annual basis for a minimum of two years after the initial
round of sampling in accordance with the approved VIMP. The specific locations for the sub-slab
vapor samples will be discussed with DEQ prior to the annual sampling events and will be based
on the previous sampling data and current activities in the pour-back areas. DEQ will be provided
