Clubhouse were reported in Request for Occupancy reports previously submitted to DEQ.
Building 4 and the Clubhouse received DEQ approval for occupancy on October 25, 2019, and
Buildings 1 and 3 received DEQ approval for occupancy on January 13, 2020.

Building 2 is an apartment building consisting of a total of five floors with multiple residential
tenant spaces on each floor. The ground floor of Building 2 is split into two levels, Building 2
Basement and Building 2 Floor 1. Carriage Houses B, C, & D are townhome-style dwellings with
a total of two floors each. Carriage House A, which was proposed in the original site plans, was
removed from the proposed plans and will not be constructed. The general construction of
foundations for each of these buildings consist of a concrete slab with load-bearing thickened
concrete footers located between units or below load-bearing walls. The split ground floor levels
in Building 2 are separated by concrete retaining walls. The approximate area of each of the
ground floor levels for the buildings are listed in the table below.

Ground Floor Level Approximate Area
(square feet)
Building 2 Basement 5,800
Building 2 Floor 1 15,000
Carriage House B Floor 1 1,350
Carriage House C Floor 1 1,350
Carriage House D Floor 1 1,100

In accordance with the Vapor Intrusion Mitigation System Design Report (VIMS Design Report),
prepared by Engineering & Land Planning Associates, Inc. (E&LP), dated April 19, 2018, and
approved by DEQ on May 17, 2018, H&H conducted above-slab VIMS inspections, pre-
occupancy testing, and sub-slab analytical sampling of Building 2 and Carriage Houses B, C, &
D. In addition, the sub-grade VIMS components, including a gravel base layer, Land Science
Vapor Vent™, and Land Science Geo-Seal® vapor barrier were installed by a Geo-seal® certified
installer/applicator, Contaminant Control Inc. (CCI), and was inspected by a Geo-Seal® certified

inspector from Intertek PSI (PSI). It should be noted that the sub-grade VIMS inspections for
Carriage House D were conducted by a Geo-Seal®-certified inspector from H&H.

The VIMS in Building 2 and Carriage Houses consist of passive vapor extraction systems with
sub-slab vapor venting coupled with the Land Science Geo-Seal™ vapor barrier. The Geo-Seal®
vapor barrier is located below the concrete slab of each ground floor level and, when applicable in
Building 2, along the vertical sections of the concrete retaining walls located between the ground
floor split levels. The Geo-Seal® vapor barrier includes 3 layers. The first layer consists of Geo-
Seal™ BASE, followed by Geo-Seal™ CORE (30-dry mils), and finished with Geo-Seal™
BOND, for a total vapor barrier thickness of approximately 53 mils. Note, the installed thickness
of the Geo-Seal CORE layer may vary slightly due to the spray applied installation method and
weather conditions. In addition, Geo-Seal Vapor VentTM is installed within a sub-slab gravel layer
to capture vapors migrating through the sub-slab annular space. The Vapor Vent™ is connected
to 4-inch poly-vinyl chloride (PVC) riser vapor conveyance piping. Following installation of sub-
slab portions of the VIMS and concrete slab, the 4-inch PVC vapor conveyance piping was run
through walls of the buildings and terminated two feet above the roofline. Empire Model TV04G
passive turbine ventilator wind driven fans were installed on the conveyance piping above the
roofline.

Following construction of the VIMS, H&H collected sub-slab vapor samples from solid 1-inch
PVC permanent monitoring points which are screened in the gravel layer beneath the Geo-Seal™
vapor barrier of the buildings. A total of six sub-slab vapor samples were collected from Building
2, a total of two sub-slab samples were collected from Carriage House C (including a duplicate
sample), and one sub-slab vapor sample was collected from each of Carriage Houses B and 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).
Calculations were run for residential use scenarios for the soil gas to indoor air exposure pathway
to calculate cumulative potential carcinogenic and non-carcinogenic risks for the sub-slab vapor

samples. The risk calculations from the analytical data of the sub-slab samples indicated that
Building 2 and Carriage Houses sub-slab vapor concentrations are within acceptable risk levels.
The methods and results of sub-slab sampling are further discussed in Section 2.3.

Based on the results of the inspection, testing, and sampling activities, H&H requests that the DEQ
Brownfields Program acknowledge compliance of Land Use Restriction (LUR) 5 of the Notice of
Brownfields Property and grant occupancy for Building 2 and Carriage Houses B, C, & D. The
Site Layout Map is provided as Figure 1 and the VIMP Master Summary is included as Table 1.

2.0 VIMS Inspections, Testing, and Sampling

During construction activities, the sub-slab portions of the VIMS were installed by CCI, a Geo-
Seal® certified installer, and inspected by PSI, a Geo-Seal® certified inspector. In addition to the
inspections performed by PSI, H&H conducted separate inspections of select sub-slab components
and inspections of above-grade components of the VIMS. As indicated in Sections 1 and 2.1, both
the sub-slab portions and above-grade components for Carriage House D were each conducted by
a Geo-Seal®-certified inspector from H&H. In addition, H&H performed pre-occupancy testing
and analytical sampling activities. The inspections, pre-occupancy testing, and sampling activities
are summarized below in the following sections.

2.1 VIMS Inspections

Between March 2019 and December 2019 (Building 2), between November 2019 and December
2019 (Carriage Houses B and C), and between August 2019 and December 2019 (Carriage House
D), the VIMS were inspected at the following various stages during the construction process,
including after completion of the Vapor Vent™ sub-slab vapor collection system and gravel
layout, after placement of the Geo-Seal® vapor barrier and prior to the concrete pour, after
installation of above-grade riser piping, and after installation of the Empire Model TV04G passive
turbine ventilator fans.

Each of the sub-slab VIMS components were inspected by PSI, while the above grade VIMS
components were inspected by H&H, with the exception of Carriage House D, for which a Geo-
Seal®-certified inspector from H&H performed the inspections. Following inspections of sub-
slab portions of the VIMS, coupons of the Geo-SealTM BASE and CORE layers were collected
and measured with calipers. Building sections with coupons which measured less than 48 mils
were resprayed with Geo-SealTM CORE until they were visually observed to be at a thickness
greater than the vapor barrier sections surrounding the area where the initial coupon was collected.
Due to the destructive nature of collecting coupon samples, additional coupons were not collected

in re-sprayed areas. A letter clarifying this procedure from PSI is included in Appendix B. In
addition, a description of vapor barrier thickness verification is presented in the daily inspection
reports provided in Appendix B. Once vapor barrier thickness was approved by PSI, of H&H for
Carriage House D, a smoke test was conducted by CCI to test that the Geo-Seal® vapor barrier
was properly installed. PSI was present during smoke testing of the sub-slab portions of the VIMS
for Building 2 and Carriage Houses B and C, and approved the results of the smoke test (as noted
in the smoke test section of the daily inspection reports in Appendix B). H&H was present for the
smoke test at Carriage House D and approved the results. In select areas, minor repairs to the Geo-
Seal® vapor barrier were made based on the results of the smoke test. Note, in the PSI inspection
documents, Carriage House B is referred to as Carriage House 1, and Carriage House C is referred
to as Carriage House 2.

Note that during H&H’s inspections of the VIMS, H&H conducted one follow-up inspection of
Building 2 due to the following:

1) During an inspection of the riser piping conducted on July 29, 2019, H&H noted that
several riser pipes were not completely plumbed from the ground floor through the roof
and that several riser pipes were not labeled. Mr. Andrew Besu of H&H conducted a follow
up inspection of Building 2 on October 29, 2019 and confirmed that all riser pipes were
properly installed and labeled.

Follow-up inspections of Carriage Houses B, C, & D were not necessary. After the inspection
activities, PSI’s approval of the smoke testing results, Vapor Vent™ installation, and Geo-Seal®
vapor barrier installation, H&H concluded that the VIMS within Building 2 and the Carriage
Houses have been properly installed by the contractor in accordance with the DEQ-approved
VIMS Design Report. The VIMS layout as-built drawings developed by PSI depicting the
locations of the final Vapor Vent™ layout, riser pipes, and monitoring point locations are included
as Appendix B. The inspection forms and field logs from H&H and PSI are included in Appendix
C.

2.2 Pilot Influence Testing

H&H conducted “pilot” influence testing on several occasions to the vent network installed below
the concrete slabs of Building 2 and Carriage Houses to verify that adequate communication was
present between the sub-slab annular space and the VIMS. The vacuum influence test in Building
2 (Basement and Floor 1) were performed on May 23, 2019. The vacuum influence tests for
Carriage House B was performed on August 30, 2019, and the tests at Carriage Houses C and D
were performed on October 28, 2019.

During influence testing, H&H utilized temporary vapor extraction fans which were attached to
the vertical riser piping. The fans use during the influence testing included RadonAway RP-145
and AMG Legend radon fans, along with a shop-vac style fan. Prior to turning the fans on, vacuum
measurements were collected at each monitoring point to establish baseline conditions. After
baseline conditions were recorded, the 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 of the monitoring points in Building 2
and Carriage Houses over varied time intervals.

Results of the influence testing for Building 2 and Carriage Houses are summarized on Table 1.
The results indicate that differential pressures measured at every monitoring point using various
vacuum levels at the fan were above the minimum depressurization reading (4 Pa) deemed
acceptable by DEQ Brownfields to demonstrate that adequate communication is present between
sub-slab annular space and the riser pipes.

VIMS Pilot Test field logs summarizing vacuum and flow measurements at each vapor extraction
point location and differential pressure measurements at each observation point are included in
Appendix C.

2.3 Sub-Slab Vapor Sampling Procedure

After completion of the VIMS components including installation of the turbine ventilator fans,
H&H collected six sub-slab vapor samples from below the ground floor levels of Building 2 on
January 8 and January 17, 2020. H&H collected one sub-slab vapor sample from below the ground
floor levels of Carriage Houses B and C on December 30, 2019, and one sample from below the
ground floor level of Carriage House D on December 11, 2019. The locations of the samples
collected from each of the ground floor levels is included in the table below.

Ground Floor Level Sub-Slab Vapor Sample Locations
Building 2 Basement MP-1/ DUP-1, MP-2
Building 2 Floor 1 MP-3, MP-4, MP-5, MP-6
Carriage House B Floor 1 CGH-B-SS-MP-1
Carriage House C Floor 1 CGH-C-SS-MP-1/Dup-20191230
Carriage House D Floor 1 CGH-D-SS-MP-1

Duplicate samples were also collected from the Building 2 Basement MP-1 parent sample, and
from the Carriage House C Floor 1 MP-1 parent sample, for quality assurance / quality control
(QA/QC) purposes.

The vacuum monitoring points were sampled by emplacing a temporary expandable plug with
sample port onto the monitoring point to create an air-tight seal, and using recommended
procedures presented in the DEQ Division of Waste Management (DWM) Vapor Intrusion (VI)
Guidance. Prior to sample collection for the samples, H&H conducted a leak test at the vacuum
measuring point by placing a shroud around the point, sampling train, and Summa canister,
saturating the air within the shroud with helium gas, then purging soil gas from the sampling point
with a GilAir vacuum pump into a Tedlar® bag.

House B-D & Building 2\21032_Radiator Specialty_Building 2 and CH B-D - Request for Occupancy_032020_Revision 1.docx

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 and fittings did not
occur and that the data collected accurately represented soil gas concentrations. Additionally, in
accordance with the DEQ-approved VIMS Design Report, an Indoor Air Building Survey form
was completed for Building 2 and the Carriage Houses, even though only sub-slab vapor samples
were collected. The Sub-Slab Soil Gas Field Forms and the Indoor Air Building Survey 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 over a 10-minute period at an approximate flow rate of 0.1 liters per minute
(L/min). During the sample collection, vacuum inside the summa canisters was recorded prior to
and following the 10-minute sampling period to ensure adequate sample volume was collected.
The samples were submitted for analysis of select volatile organic compounds (VOCs) by EPA
Method TO-15 to Con-Test Analytical Laboratory (Con-Test), a nationally accredited laboratory.
The select VOCs included compounds that were detected in Site groundwater or soil gas during
previous assessment activities as documented in the Brownfields Assessment Report Revision 1
prepared by H&H and dated March 2, 2018.

A tabular summary of the post VIMS construction sub-slab soil gas analytical results is presented
in Table 1. The laboratory analytical reports with chain of custody records are provided as
Appendix D. The laboratory analytical results were compared to the DEQ DWM Residential Sub-
Slab and Exterior Soil Gas Screening Levels (SGSLs) dated February 2018.

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). 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 from Building 2 (MP-1/DUP-1) and from Carriage
House C (CGH-C-SS-MP-1/Dup20191230) were used in the risk calculator.

2.4 Sub-Slab Vapor Sampling Results

The results of analysis indicate that several VOCs were detected above laboratory method
detection limits (MDLs) at low concentrations in the samples from each of the monitoring points.
However, no compounds were detected at concentrations above Residential SGSLs in any of the
samples.

Building 2
The risk calculators indicated the calculated residential LICRs for the samples collected from the
ground floor levels of Building 2 ranged from 8.6 x 10-9 to 1 x 10-6, which are notably below the
acceptable risk level of 1 x 10-4. The calculated residential HI for the samples collected from
Building 2 ranged from 0.0019 to 0.23, which are below the acceptable threshold level of 1.
Therefore, the VOC vapor concentrations detected below the footprint of Building 2 do not appear
to pose an unacceptable risk to future residential occupants of the building.

Carriage House B
The risk calculators indicated the calculated residential LICR for the sample collected from the
ground floor level of Carriage House B was 1.3 x 10-9, which is notably below the acceptable risk
level of 1 x 10-4. The calculated residential HI for the sample collected from Carriage House B is
0.00092, which is notably below the acceptable threshold level of 1. Therefore, the VOC vapor
concentrations detected below the footprint of Carriage House B do not appear to pose an
unacceptable risk to future residential occupants of the building.

Carriage House C
The risk calculators indicated the calculated residential LICR for the samples collected from the
ground floor level of Carriage House C to be 1.1 x 10-6, which is notably below the acceptable risk
level of 1 x 10-4. The calculated residential HI for the sample collected from Carriage House C is
0.13, which is notably below the acceptable threshold level of 1. Therefore, the VOC vapor
concentrations detected below the footprint of Carriage House C do not appear to pose an
unacceptable risk to future residential occupants of the building.

Carriage House D
The risk calculators indicated the calculated residential LICR for the sample collected from the
ground floor level of Carriage House D to be 0.0, indicating no constituents which pose
carcinogenic risk were detected above laboratory detection limits. The calculated residential HI
for the sample collected from Carriage House D is 0.0021, which is notably below the acceptable
threshold level of 1. Therefore, the VOC vapor concentrations detected below the footprint of
Carriage House D do not appear to pose an unacceptable risk to future residential occupants of the
building.

3.0 Summary and Recommendations

Based on the results of our recent VIMS inspections, testing, and sampling activities, H&H
certifies that the VIMS associated with Building 2 and Carriage Houses B, C, & D at the
Broadstone Bryant Park site has been properly installed per the approved VIMP and there is
adequate communication between the sub-slab annular space and the VIMS. In addition, based
upon the sub-slab vapor sampling results, the VOC vapor concentrations detected in the sub-slab
do not appear to pose an unacceptable risk to future occupants of these buildings. Therefore, H&H
requests that the DEQ Brownfields Program acknowledge compliance of LUR 5 of the Notice of
Brownfields Property and grant occupancy for Building 2 and Carriage Houses B, C, & D.

In accordance with the approved VIMP, post-occupancy sub-slab vapor samples will be collected
from each of the monitoring points of the ground floor levels (listed in Section 2.3) in Building 2
and the Carriage Houses on an annual basis for a period of two years following building
completion. After the two-year period, the environmental consultant for the BBPA or current
property owner, and DEQ, will reassess the need to continue collecting sub-slab vapor samples.

A construction completion report will be submitted under separate cover following the completion
of all buildings discussed in the approved Vapor Intrusion Mitigation System Design Report.
Note, per the approved VIMP, an operational & maintenance (O&M) plan will also be developed
for the operator of the VIMS to ensure proper functionality of the system post-construction. The
O&M Plan will include instructions for semi-annual post-occupancy inspections. Inspection logs
of semi-annual inspections will be submitted annually with the Land Use Restriction Update Form
for the Site. The O&M plan will be developed and submitted to DEQ with the construction
completion report.

Re: Vapor Barrier Inspection
Broadstone Bryant Park Apartments
Northwest Quadrant of Wilkinson Blvd and Suttle Avenue
Charlotte, Mecklenburg County, North Carolina
PSI Project Number: 04571227-1
Dear Mr. Helms:
Professional Service Industries, Inc (PSI) an Intertek company is submitting this letter, as you requested, for
clarification regarding the inspections PSI conducted during the installation of the sub-slab depressurization
system for the above referenced project. PSI conducted the field inspections and documented the inspections
on daily field logs. As part of the inspection PSI collected coupon samples of the vapor barrier system. These
coupon samples were used to verify the thickness of the vapor barrier in various location on each of the building
slabs. When the thickness of the coupon sample was not to the design specifications PSI had the vapor barrier
installer respray the areas. Since the coupon sampling is destructive to the vapor barrier additional coupon
samples were not collected after the respraying the areas that failed the original thickness testing.
Please call with any questions you may have, or if you require any additional information about this matter.
Respectfully Submitted,
Professional Services Industries, Inc
Bryan M. Lucas
Department Manager/Principal Consultant
