Brownfields Project No. 20094-16-036 H&H Project No. BKL-001 Dear Joselyn:
1.0 Introduction

On behalf of Brookline Homes, LLC, Hart & Hickman, PC (H&H) has prepared this Vapor
Intrusion Mitigation System (VIMS) Construction Completion Report for residential townhome
structures Buildings 4 through 7, located on the Former Belmont Dyers Brownfields property in
Belmont, Gaston County, North Carolina (Site). The Site is part of the North Carolina Department
of Environmental Quality (DEQ) Brownfields Program (Brownfields Project No. 20094-16-036).
The subject Site is being redeveloped with a residential development known as the Aberfoyle
Village (attached single-family townhome units) and Riverside Flats (multi-family apartments)
and totals approximately 11 acres which are situated on the western bank of the Catawba River.

This letter report summarizes vapor intrusion mitigation system (VIMS) inspections, pre-
occupancy testing, and analytical sampling activities associated with the Aberfoyle Village
townhome units constructed by Brookline Homes which comprise Building 4 (4 units), Building
5 (6 units), Building 6 (4 units), and Building 7 (4 units). Building 5 is situated on one concrete

installation activities associated with Building 7. Additional DEQ comments where received on
April 7, 2020, and responses to the comments are included herein this Revision 1 report.
H&H conducted the VIMS inspections, pre-occupancy testing, and sampling activities in
accordance the DEQ-approved Vapor Intrusion Mitigation Plan (VIMP) Revision 1 dated March
19, 2019, and supplemented by the Request for VIMP Modifications – Revision 2 (VIMP
Modifications) dated April 14, 2020,and subsequently approved by DEQ on April 15, 2020. The
residential units were recently constructed and are currently owned by Brookline Homes for sale
to individual homeowners. There are a total of 14 townhome buildings at the Site, identified as
Buildings 1 through 14, and three apartment buildings, identified as Buildings 15 through 17. The
apartment buildings were constructed by a separate builder, Mission Properties, LLC. Of these 14
townhome structures vapor mitigation controls were required in the VIMP for four of the buildings,
Buildings 4 through 7, located on the southern portion of the Site. Vapor mitigation controls were
not required in any other site buildings. Brookline has voluntarily installed sub-slab venting
systems in Buildings 8 and 9. A discussion of analytical sampling results of Buildings 8 and 9
will be provided under separate cover.
The Former Belmont Dyers Brownfields Site layout and as-built drawings are included as Figures
VM-1A through VM-1D in Appendix A. A VIMP Master Summary is included as Table 1. A
summary of the VIMS installation inspection, pre-occupancy testing, and analytical sampling
activities are provided in the following sections. Based on the results of the inspections, testing,
and sampling activities, H&H requests that the DEQ Brownfields Program acknowledge
compliance with land use restriction (LUR) No. 6c from the Notice of Brownfields Property for
Buildings 4 through 7 (Units 53 through 70).

2.0 VIMS Inspections, Testing, and Sampling

During construction activities, H&H conducted VIMS inspections, pre-occupancy testing, and
sampling activities which are summarized below in the following sections. The VIMS under
Buildings 4 through 7 are comprised of a passive sub-slab vapor extraction system utilizing a vapor
vent pipe system and Empire Model TV04G wind driven turbine fans coupled with the Stego
Industries, LLC, Stego-Wrap® 15-mil vapor barrier (Stego-Wrap) installed below the concrete
slab of each building.

Prior to beginning VIMS construction activities, H&H noted that interior monitoring points in the
DEQ-approved VIMP were proposed to be placed under the stairwells within tenant living spaces
which would be inaccessible during future monitoring activities. For ease of access, the
monitoring points were moved from the interior units to a more suitable location at the rear of each
unit where they can be easily accessed from an exterior access port during future monitoring
activities. The intake of these re-located monitoring points are located approximately 5 ft from
the exterior walls. The monitoring point modifications were approved by the engineer-of-record
(EOR), a North Carolina Professional Engineer (PE), and the revised locations are documented in
the as-built figures (Appendix A).

Each townhome building includes interior and exterior units and each unit includes a garage. The
garage for the interior units is detached (separated) from the living space of the corresponding
townhome. The garage for the exterior units is connected to the living space of the townhome.
The separated garges share a roof with the connected garages, but the garages are separated by a
thickend slab footer and continuous wall. Each garage is not designed to be an occupied living
space and does not contain heating, ventilation, and air conditioning (HVAC) systems.
Furthermore, the Aberfoyle Village Homeowner’s Association (HOA) covenant only permits the
garage to be used for parking vehicles. Therefore, the garages are not permitted to be used for or
converted to a living space. In accordance with the approved VIMP, the garages that are connected
to the exterior units, although not conditioned, received the Stego-Wrap vapor barrier and sub-slab
Ms. Joselyn Harriger, PG April 16, 2020 – Rev 1 Page 5

S:\AAA-Master Projects\Ralph Falls (RPH)\BKL-001 - Belmont Dyers\Occupancy Requests\Buildings 4-7 combined and revised\Revision 1\20094_Belmont Dyers_Buildings 4-7_Request for Occupancy_ Revision 1_041620.docx
vent piping because these garages are connected to living spaces. The approved VIMP did not
require a vapor barrier or vent piping installed below the separated garages because these areas do
not connect with living spaces. However, in an abundance of caution, Brookline Homes elected
to also install the Stego-Wrap vapor barrier below the slabs of the detached garages. The
installation of the vapor barrier below the detached garages was approved by the EOR and
documented in the as-built figures (Appendix A).

2.1 VIMS Inspections

H&H conducted VIMS inspections of Building 4 (July 15, 2019 to October 3, 2019), Building 5
(July 22, 2019 to October 7, 2019), Building 6 (August 12, 2019 to October 14, 2019), and
Building 7 (August 12, 2019 to October 24, 2019), during the following four stages of the
construction process:

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

H&H performed inspections as necessary to confirm that the system was properly installed during
each of the four phases of VIMS construction. If repairs or corrections to the VIMS were required,
follow-up inspections were conducted by H&H to verify the system was properly installed. H&H
performed follow-up inspections for VIMS components for Buildings 4, 6, and 7 for the reasons
listed below. It was not necessary to perform follow-up inspections for Building 5.

Building 4
1) During an inspection (Inspection 1) of Building 4 conducted on July 15, 2019, H&H noted
that soil was mixed with the sub-slab gravel. Therefore, H&H requested that soil and fines
Ms. Joselyn Harriger, PG April 16, 2020 – Rev 1 Page 6

S:\AAA-Master Projects\Ralph Falls (RPH)\BKL-001 - Belmont Dyers\Occupancy Requests\Buildings 4-7 combined and revised\Revision 1\20094_Belmont Dyers_Buildings 4-7_Request for Occupancy_ Revision 1_041620.docx
be removed from the sub-slab gravel. Additionally, H&H noted that solid sections of sub-
slab piping did not have the adequate slope to drain water toward the sub-surface. H&H
conducted a follow up inspection of Building 4 on July 26, 2019 and confirmed that clean
gravel was present below Building 4 and that pipe slope had been corrected.

2) During an inspection (Inspection 2) of Building 4, on July 30, 2019, H&H requested that
the builder add additional liner into the attached garages to provide proper overlap and tie-
in of the vapor barrier below the garage. This excess was added and the H&H confirmed
the vapor barrier installation for the living spaces was properly installed. On August 1,
2019, a follow-up inspection for the vapor barrier of the garage space was conducted and
H&H confirmed the vapor barrier was properly installed.

3) During an inspection (Inspection 3) of Building 4 conducted on September 27, 2019, H&H
noted that labels were not present on horizontal sections of the riser piping. H&H
conducted a follow-up inspection later that day and confirmed that the correct labeling was
present on the riser piping.
4) During an inspection (Inspection 4) of Building 4 conducted on September 27, 2019, H&H
noted that a reducer was not used to attach the passive ventilator fan. H&H requested
installation of a reducer as shown in detail 5 of the VIMP. H&H conducted a follow-up
inspection on October 3, 2019 and confirmed that the fan was installed correctly.

Building 6
1) During an inspection (Inspection 1) of Building 6 conducted on August 12, 2019, H&H
noted that select sections of solid sub-slab VIMS piping should be replaced with slotted
piping to provide additional surface area for vapor collection. Additionally, H&H noted
that sub-slab portions of each of the monitoring points should be extended so that the
monitoring point intake was at least 5 ft from the edge of the building slab. H&H conducted
a follow up inspection of Building 6 on August 13, 2019 and confirmed that these portions
Ms. Joselyn Harriger, PG April 16, 2020 – Rev 1 Page 7

S:\AAA-Master Projects\Ralph Falls (RPH)\BKL-001 - Belmont Dyers\Occupancy Requests\Buildings 4-7 combined and revised\Revision 1\20094_Belmont Dyers_Buildings 4-7_Request for Occupancy_ Revision 1_041620.docx
of the sub-slab solid VIMS piping had been correctly replaced with slotted piping and that
monitoring point intakes were at least 5 ft from the edge of the building slab.

2) Following the initial inspection (Inspection 2) of the vapor barrier in Building 6 on August
16, 2019 of the vapor barrier, H&H conducted follow-up vapor barrier inspections for
sections of the building on August 14, 20, and 22, 2019. These follow-up inspections were
conducted because the vapor barrier was installed in sections for this building. H&H
confirmed that the vapor barrier for each building section was properly installed following
any necessary repairs.

Building 7
1) During an inspection (Inspection 1) of Building 7 conducted on August 12, 2019, H&H
noted that sub-slab portions of each of the monitoring points should be extended so that
the monitoring point intake was at least 5 ft from the edge of the building slab.
Additionally, H&H requested that the slotted piping be extended closer to the thickened
slab. H&H’s conducted a follow-up inspection on August 13, 2019 and confirmed that the
monitoring point intakes were at least 5 ft from the edge of the building slab, and that
slotted piping had been extended closer to the thickened slab.

2) During an inspection (Inspection 2) of Building 7 conducted on August 20, 2019 in the
garage spaces, H&H noted the vapor barrier seams needed repairs. H&H conducted a
follow-up inspection on August 22, 2019 and confirmed that the repairs were adequate and
the vapor barrier in the garage spaces had been properly installed.

After completion of inspection and re-inspection activities, H&H concluded that the VIMS within
each of the residential units were properly installed by the contractor(s) in general accordance with
the DEQ-approved VIMP. VIMS Inspection Logs are included in Appendix B. A photographic
log with representative photographs of the VIMS installation are included in Appendix C.

2.2 Pilot Influence Testing

H&H conducted “pilot” influence testing on the vent networks installed below the concrete slabs
of Buildings 4 through 7 to verify that adequate communication was present between the sub-slab
annular space and the VIMS. During influence testing, H&H utilized temporary vapor extraction
fans which were attached to the vertical riser pipes. 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 for Buildings 4
through 7 over varied time intervals.

Building 4
On August 30th and September 3rd, 2019, H&H conducted influence testing on the vent network
installed below the concrete slab of Building 4. The results of pilot test activities conducted on
August 30, 2019 indicated that monitoring MP-4 was not adequately connected to the sub-slab
annular space beneath Building 4. Therefore, under direction of H&H, Brookline Homes
subsequently excavated the soil surrounding monitoring point MP-4 from the ground surface to
where the piping extends through the concrete slab footer. Once the piping was exposed, it was
observed that the ineffective monitoring point pipe had been inadvertently damaged during
construction. The monitoring point was then repaired by removing and replacing the damaged
portion of the pipe.

After the repairs were complete, subsequent pilot testing activities were conducted by H&H on
September 3, 2019 at monitoring points MP-4, MP-5, and MP-6. The results indicated that the re-
installed monitoring point was repaired and that adequate connectivity was present between the
VIMS and the gravel in the area of these monitoring points.

Differential pressures measured at the monitoring points ranged from 31 to 46 Pa during the testing
which are 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.

Building 5
On August 30th and September 3rd, 2019, H&H conducted influence testing on the vent network
installed below the concrete slab of Building 5. Differential pressures measured at the monitoring
points of Building 5 ranged from 16 to 84 Pa. Influence testing results indicate that differential
pressures measured in Building 5 and are 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.

Building 6
On September 3rd, 2019, H&H conducted influence testing on the vent network installed below
the concrete slab of Building 6. Differential pressures measured at the monitoring points of
Building 6 ranged from 22 to 34 Pa. Results of influence testing indicate that differential pressures
measured in Building 6 are 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.

Building 7
On September 3rd, 2019, H&H conducted influence testing on the vent network installed below
the concrete slab of Building 7. Differential pressures measured at the monitoring points of
Building 7 ranged from 22 to 39 Pa. Results of influence testing indicate that differential pressures
measured in Building 7 are 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 for Buildings 4 through
7 at each vapor extraction point location and differential pressure measurements at each
observation point are included in Appendix A.

2.3 Sub-Slab Vapor Sampling

In accordance with the VIMP Modifications, H&H collected one sub-slab vapor sample for every
two townhome units from below Building 4 (two samples), Building 5 (three samples), Building
6 (two samples), and Building 7 (two samples) to determine if acceptable vapor intrusion risk
levels were present below the slab. The table below summarizes the location and date for each of
the sub-slab samples. Refer to Figures VM-1A through VM-1D in Appendix A for the monitoring
point locations.

H&H also collected duplicate sub-slab samples (DUP-1) along with the MP-6 parent sample for
Building 4, with the MP-5 parent sample for Building 5, with the MP-3 parent sample for Building
6, and with the MP-3 parent sample for Building 7 for quality assurance/quality control (QA/QC)
purposes.

2.3.1 Sub-Slab Vapor Sampling Procedure

H&H collected samples from the vacuum monitoring points in accordance with Division of Waste
Management (DWM) Vapor Intrusion (VI) Guidance. A temporary expandable plug was placed
within the sample port into the point to create an air-tight seal. 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 Soil Gas Field Forms are included in Appendix A.

Following a successful leak check, the sub-slab samples were collected into batch-certified 1-liter
or 6-liter stainless steel Summa canisters connected to an airflow regulator preset by the laboratory
to collect the sample at a flow rate of approximately 0.1 L/min. Vacuum inside the summa
canisters was recorded prior to and following the sampling period to ensure adequate sample
volume was collected. The samples were submitted for analysis of full-list volatile organic
compounds (VOCs) by EPA Method TO-15 to Con-Test Analytical Laboratory (Con-Test). The
laboratory analytical results were compared to the DEQ DWM Residential Sub-Slab and Exterior
Soil Gas Screening Levels (SGSLs) dated February 2018. A tabular summary of the sub-slab soil
gas analytical results is presented in Table 1. The laboratory analytical report and chain of custody
record is provided as Appendix D.

After receipt of the data, the detected sub-slab soil gas concentrations were entered in DEQ’s
Vapor Intrusion Screening Level (VISL) Soil Gas to Indoor Air Risk Calculator (December 2019
version) to calculate cumulative risks using the compounds detected for each sub-slab sample
Ms. Joselyn Harriger, PG April 16, 2020 – Rev 1 Page 12

S:\AAA-Master Projects\Ralph Falls (RPH)\BKL-001 - Belmont Dyers\Occupancy Requests\Buildings 4-7 combined and revised\Revision 1\20094_Belmont Dyers_Buildings 4-7_Request for Occupancy_ Revision 1_041620.docx
under a residential use scenario. Copies of the risk calculators are provided in Appendix E and
calculated Lifetime Incremental Cancer Risk (LICR) and Hazard Index (HI) values are also
included in Table 1.

2.3.2 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. As a conservative measure, for samples that included a parent and a duplicate sample,
the highest concentration of each detected compound was entered into the risk calculators. The
calculated LICR and HI for the samples collected from the monitoring points of each building are
described below.

Building 4
As indicated in Table 1, the calculated LICR for the sample collected from MP-3 was 6.5 x 10-7
and the calculated LICR for the sample collected from MP-6 was 2.3 x 10-7, which are notably
below the acceptable risk level of 1 x 10-4. The HI for MP-3 was calculated at 0.023 and the HI
for MP-6 was calculated at 0.014, which are notably below the threshold of 1. Therefore, VOC
vapor concentrations detected below the slab of Building 4 do not appear to pose an unacceptable
risk to future occupants of the residential townhome units.

Building 5
The risk calculators indicated the calculated residential LICRs for the samples collected from
Building 5 (monitoring points MP-3, MP-5, and MP-8) ranged from 1.4 x 10-8 to 5.5 x 10-7, which
are notably below the acceptable risk level of 1 x 10-4. The calculated residential HI for the samples
collected from Building 5 ranged from 0.0037 to 0.069, which are notably below the acceptable
threshold level of 1. Therefore, the VOC vapor concentrations detected below the slab of Building
5 do not appear to pose an unacceptable risk to future residential occupants of the townhome units.

Building 6
As indicated in Table 1, the calculated LICR for MP-3 was 2.2 x 10-9 and the calculated LICR for
MP-6 was 1.3 x 10-7, which are notably below the acceptable risk level of 1 x 10-4. The HI for
MP-3 was calculated at 0.0026 and the HI for MP-6 was calculated at 0.0022, which are notably
below the threshold of 1. Therefore, VOC vapor concentrations detected below the slab of
Building 6 do not appear to pose an unacceptable risk to future occupants of the residential
townhome units.

Building 7
As indicated in Table 1, the calculated LICR for MP-3 was 1.5 x 10-7 and the calculated LICR for
MP-6 was 1 x 10-6, which are notably below the acceptable risk level of 1 x 10-4. The HI for MP-
3 was calculated at 0.007 and the HI for MP-6 was calculated at 0.028, which are notably below
the threshold of 1. Therefore, VOC vapor concentrations detected below the slab of Building 7 do
not appear to pose an unacceptable risk to future occupants of the residential townhome units.

3.0 Summary and Recommendations

Based on the results of the recent VIMS inspection, testing, and sampling activities, H&H certifies
that the VIMS associated with the Former Belmont Dyers Buildings 4 through 7 (Units 53 through
70) have been properly installed in accordance with the DEQ-approved VIMP and VIMP
Modifications. The construction of each VIMS component of the Site buildings are complete.
Influence testing verified that there is adequate communication present between sub-slab annular
space and the riser pipes. In addition, based upon the sub-slab vapor sampling results, the VOC
vapor concentrations detected below the sub-slabs in these buildings do not appear to pose an
unacceptable risk to future occupants of the residential structures. Therefore, H&H requests that
the DEQ Brownfields Program acknowledge compliance with land use restriction (LUR) No. 6c
from the Notice of Brownfields Property for Buildings 4 through 7 (Units 53 through 70).

In accordance with VIMP Modifications, sub-slab vapor samples will be collected from Buildings
4 through 7 on an annual basis for the next two years. The samples will be collected at the same
frequency, two per Building 4, 6, and 7, and three per Building 5, as the pre-occupancy sampling
using the methods described in this report. A report with the post-occupancy sub-slab vapor
sampling results and risk calculators will be submitted to DEQ following each sampling event. In
addition, in accordance with the VIMP Modifications, inspections of the building foundation and
select VIMS components will be conducted on a semi-annual basis for the first year of operation
and recorded on the Inspection Form – Vapor Intrusion Mitigation System included in Appendix
F. Items observed during the visual inspection that may require repairs will be reported to the
Aberfolye Village HOA and subsequent a North Carolina PE. After the first year of operation, a
reduced inspection frequency for additional inspections may be evaluated and recommended to
DEQ for approval. The inspection forms will be submitted annually to DEQ along with the annual
land use restriction update (LURU).

FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank /laboratory control sample recovery outside of control limits. Data validation is not
affected since all results are "not detected" for all samples in this batch for this compound and bias is on the high
side.
L-01
Initial calibration verification (ICV) did not meet method specifications and was biased on the high side. Data
validation is not affected since sample result was "not detected" for this compound.
V-36
Compound fails the method requirement of 70-130% recovery for the LCS. Is classified by the lab as a difficult
compound and passes the in house limits of 50-150%.
