Vapor Intrusion Mitigation Plan – Revision 1
Sugar Creek Multifamily Apartments
Metromont Concrete Facility
Charlotte, North Carolina
Brownfields Project No. 22040-18-060
H&H Job No. S2K-001
1.0 Introduction
On behalf of S2K Charlotte QOZB LLC (S2K Charlotte), Hart & Hickman, PC (H&H) has
prepared this Vapor Intrusion Mitigation Plan (VIMP) for installation of a vapor intrusion
mitigation system (VIMS) during construction of a proposed apartment building at the
Metromont Concrete Facility Brownfields property (Brownfields Project No. 22040-18-060).
Comments from the North Carolina Department of Environmental Quality (DEQ) to the VIMP –
Revision 0 dated August 29,2023 were received on October 6, 2023, and responses and revisions
to the comments are included herein.
The Brownfields property is located at 3927, 4101, and 4109 Greensboro Street and 200 E. Sugar
Creek Road in Charlotte, Mecklenburg County, North Carolina (Site). The Site consists of three
contiguous parcels (Mecklenburg County Parcel identification Nos. {PINs} 09108106, 0910899,
and 19108126) that collectively total approximately 18.3 acres of land located in a rapidly
densifying area of the NoDa neighborhood in close proximity to the LYNX Blue Line light rail
corridor and uptown Charlotte. A Site location map is provided as Figure 1, and the Site and
surrounding area are shown in Figure 2.
To address potential environmental concerns associated with historical on-Site and nearby off-
Site operations, the Site was entered into the Brownfields Redevelopment Section and received a
Letter of Eligibility dated July 6, 2018. Following completion of assessments and risk
evaluations, a Notice of Brownfields Property was recorded on the property deed on December
2, 2019.
Redevelopment of the Brownfields property will be completed in phases. This VIMP has been
prepared for a high-density multifamily apartment building proposed for construction on the

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
westernmost Site parcel (PIN 09108106) known as Sugar Creek Multifamily Apartments. The
ground level components of the proposed seven-story residential apartment building will include
living spaces, amenity areas, a leasing office, a courtyard, and a parking garage. Details of the
proposed building are shown in VIMS design sheets provided in Appendix A, and an overlay of
the proposed apartment building is shown in Figure 3.

Redevelopment plans for the central and eastern portions of the Site have not been finalized. A
VIMP for future buildings proposed for construction in other portions of the Brownfields
property will be submitted to DEQ for review and approval under separate cover.

1.1 Background

The Site was predominantly undeveloped wooded land until the 1950s when the Site was
developed with concrete manufacturing buildings. The Site was utilized as a concrete
manufacturing facility by multiple tenants from the early to mid-1950s until approximately 1997.
The Site was occupied by Exposaic Industries, Inc. (Exposaic) until 1995 and Metromont
Corporation (Metromont) for structural pre-cast concrete manufacturing operations from 1995
until February 2019. In 2019, the southwestern portion of the Site was temporarily utilized by a
contractor for the City of Charlotte, Johnson Brothers, Inc., as a temporary staging location for
equipment, materials, rails, poles, and pre-cast concrete used for installation of the light rail.

In 2022, the concrete manufacturing buildings were razed and limited grading and excavations
for the installation of a stormwater collection and retention system were completed. The
stormwater infrastructure activities were completed in accordance with the DEQ-approved
Environmental Management Plan dated July 25, 2022. The Site is currently vacant undeveloped
land with foundations and remnants of select former concrete manufacturing structures.

1.2 Summary of Previous Environmental Assessment Activities

H&H reviewed several reports to obtain additional information and document previous
environmental assessments completed at the Site. A brief summary of the sampling activities
3
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
and results pertinent to potential vapor intrusion for the proposed apartment building is provided
below. Pertinent historical analytical documentation is provided in Appendix B.
1995 UST Closure Activities
A UST Closure Report prepared by Trigon Engineering Consultants, Inc. (Trigon) on September
15, 1995 indicates that Exposaic operations at the Site included use of the following USTs:
o Tank No. 1 – 8,000-gallon diesel UST installed in April 1960
o Tank No. 2 – 8,000-gallon gasoline UST installed in April 1975
o Tank No.3 – 8,000-gallon fuel oil UST installed in April 1962
o Tank No. 4 – 6,000-gallon fuel oil UST installed in April 1954
Information provided in the UST Closure Report indicates that Trigon removed Tank No. 1,
Tank No. 2, and Tank No. 3 in August 1995. Tank No. 4 was closed in-place by filling the UST
with concrete due to inaccessibility for heavy machinery needed to remove the tank. The
approximate locations of the former USTs are shown in Figure 3.
During removal of the tanks, Trigon observed evidence of a release to soil beneath Tank No. 1
and beneath the dispenser adjacent to Tank No. 2. No apparent petroleum contamination was
observed in the Tank No. 3 UST basin. Approximately 25 cubic yards of potentially impacted
soil was excavated from the Tank No. 1 diesel UST basin and approximately 5 cubic yards of
potentially impacted soil was excavated from the Tank No. 2 gasoline UST dispenser system
area. Laboratory analytical results of UST closure soil samples indicated that total petroleum
hydrocarbons as diesel range organics (TPH-DRO) were detected above the laboratory reporting
limits in soil samples collected beneath the Tank No. 3 fuel oil UST (274 milligrams per
kilogram [mg/kg]) and beneath the Tank No. 2 gasoline UST dispenser system (761 mg/kg).
TPH concentrations were not detected above the laboratory reporting limits for closure soil
samples collected for the Tank No. 1 and Tank No. 2 UST basins.
Phase III Groundwater Assessment

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
H&H reviewed a Phase III Groundwater Assessment report prepared by J.L. Rodgers and
Callcott Engineers, Inc. (R&C) dated May 1996. Information provided in the report indicates
that in July 1996, groundwater samples were collected from five groundwater monitoring wells
and submitted for laboratory analysis of volatile organic compounds (VOCs) and Acid/Base
Neutral Extractables.
Laboratory analytical results indicated that naphthalene (22 micrograms per liter [µg/L]), 1,2,4-
trimethylbenzene (11 µg/L), and 2-methylnaphthalene (25 µg/L) were detected at concentrations
above the laboratory reporting limits in a groundwater sample (MW-1) collected in the vicinity
of the abandoned fuel oil UST (Tank No. 4). The naphthalene concentration exceeded the DEQ
2L Groundwater Quality Standard (2L Standard) of 6 µg/L. No other compounds were detected
at concentrations exceeding the 2L Standards in the July 1996 groundwater samples collected at
the Site.
Based on results of the UST closure activities completed at the Site by Trigon and the subsequent
assessment activities completed at the Site by R&C, the DEQ UST Section Guidelines indicated
that a Phase I Limited Site Assessment (LSA) should be performed to further evaluate risks
associated with the release incident (Incident No. 15459).
2018 Phase I and II ESA
In 2018, ECS Southeast, LLP (ECS) completed a Phase I and Phase II Environmental Site
Assessment (ESA) activities at the Site to further evaluate the potential for impacts from on-Site
and nearby off-Site operations. As part of Phase II ESA activities, ECS collected four (4) soil
samples (SB-1, SB-3, SB-5, and SB-6) and the three (3) groundwater samples (GW-1, GW-4,
and GW-6) for laboratory analysis.
Soil laboratory analytical results did not identify TPH at concentrations exceeding the DEQ UST
Section Action Levels in the Phase II ESA soil samples collected at the Site. Groundwater
sample laboratory analytical results indicate that several compounds were detected at
concentrations above the laboratory reporting limits in the groundwater sample collected in the
northwestern and downgradient portion of the Site (GW-1). Several chlorinated compounds
5
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
including trichloroethene (TCE), cis-1,2-dichloroethene, and vinyl chloride were detected at
concentrations exceeding the DEQ groundwater screening criteria in the groundwater sample
collected from GW-1. No compounds were detected at concentrations above the DEQ
groundwater screening criteria in GW-4 and GW-6, located in the eastern and southern portions
of the Site, respectively.
Phase I LSA
In January and February 2019, H&H completed Phase I LSA soil and groundwater sampling
activities at the Site to further the potential for impact in the areas of the three former USTs and
the abandoned UST. Soil and groundwater samples were collected from each LSA soil
boring/temporary monitoring well and submitted for laboratory analyses in accordance with the
DEQ UST Section Guidelines based on the use of each former tank. Sampling activities and
results are provided in a Phase I Limited Site Assessment Report prepared by H&H and dated
March 18, 2019. A brief summary of the Phase I LSA sampling results is provided below.
Soil samples were collected from depths corresponding to the base of the excavated and
abandoned USTs as observed and reported by Trigon during tank closure activities completed in
1995. Soil sample analytical results indicate that no compounds were detected at concentrations
exceeding the DEQ UST Section Maximum Soil Contaminant Concentrations (MSCCs) in the
LSA soil samples.
Laboratory analytical results indicate that low levels of several petroleum-related compounds
were detected at concentrations above the laboratory method detection limits, but below the DEQ
UST Section Groundwater Quality Standards (GWQSs) in the area of each former UST. In
addition, low levels of the tentatively identified compounds (TICs) elcosene (25 micrograms per
liter [µg/L]) and vanillin (14 µg/L) were detected at concentrations above the laboratory method
detection limits in the TW-1 groundwater sample collected downgradient of the former diesel
UST (Tank No.1). No GWQS has been established for elcosene and vanillin.
A low level (2.6 µg/L) of the chlorinated solvent tetrachloroethylene (PCE) was detected at a
concentration above the GWQS of 0.7 µg/L in groundwater sample TW-2 collected
downgradient of the former gasoline tank (Tank No. 2). No other target compounds were

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
detected above applicable groundwater standards. No compound concentrations exceeded DEQ-
defined Gross Contamination Levels (GCLs).
Based on results of the Phase I LSA and following recordation of a groundwater use restriction
on the property deed, the DEQ UST Section issued a No Further Action letter for the release
incident dated July 10, 2019.
1.3 Brownfields Assessment Activities
To address environmental concerns associated with historical on-Site operations, the Site was
entered into the DEQ Brownfields Redevelopment Section and received an eligibility in a letter
dated July 6, 2018. A kick-off/data gap meeting with DEQ Brownfields personnel was held on
September 20, 2018, to discuss historical uses of the Site, available environmental information,
proposed redevelopment plans, data gaps, and the proposed schedule for completing the
Brownfields Agreement. Based on review of available information from previous assessments
and the residential nature of the proposed redevelopment of the Site, DEQ Brownfields personnel
requested additional data gap assessment.
To address DEQ Brownfields requests for Site assessment activities, H&H submitted a
Brownfields Assessment Work Plan (Work Plan) which received DEQ approval in an email
dated January 22, 2019. Brownfields assessment activities were completed at the Site in January
and February 2019, and the results of the assessment are documented in the Brownfields
Assessment Report prepared by H&H and dated March 12, 2019. A brief summary of the
Brownfields assessment activities and results is provided below.
Brownfields assessment activities included the collection of soil, groundwater, and soil gas
samples for laboratory analysis to further evaluate subsurface conditions for potential impacts
and to evaluate risks associated with residential redevelopment of the Site. The 2019
Brownfields assessment sample locations are shown in Figure 3 and Figure 4 and a summary of
the sampling activities and results is provided below.

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
Soil Assessment Activities
H&H collected four (4) soil samples near former USTs and historical acid wash operations (TW-
1 through TW-4). H&H also collected two (2) shallow background soil samples to establish
Site-specific background concentrations for naturally occurring metals.
Laboratory analytical results did not identify organic compounds at concentrations above the
DEQ Residential Preliminary Soil Remediation Goals (PSRGs) in the soil samples collected
during 2019 Brownfields assessment activities. Several metals were detected at concentrations
above laboratory reporting limits but below the DEQ PSRGs and consistent with Site-specific
ranges for naturally occurring metals.
In summary, results of soil assessment activities completed at the Site indicate that there is no
evidence of a significant release in the area of the former USTs or in the area of former acid
wash operations, and Site soils do not appear to pose a potential vapor intrusion risk to the
proposed apartment building.
Groundwater Assessment Activities
Nine (9) temporary groundwater monitoring wells (TW-1 through TW-9) were installed at the
Site in the areas of the former USTs and historical acid wash operations, along upgradient Site
boundaries, and near former temporary well GW-1 located in the northwestern and downgradient
portion of the Site to confirm the presence of chlorinated solvent impacts reported by others. As
depicted in Figure 3, temporary monitoring wells TW-3 and TW-8 were located nearest to the
proposed apartment building.
With the exception of low-level aliphatic hydrocarbon fractions in the TW-3 groundwater
sample, results of groundwater sampling did not identify organic compounds at concentrations
above the DEQ Residential Vapor Intrusion Groundwater Screening Levels (GWSLs) in the
TW-3 and TW-8 samples. Several metals were detected at concentration above the laboratory
method detection limits, but below the 2L Groundwater Standards. Mercury was not detected at
concentrations above the laboratory detection limits in the groundwater samples collected during
2019 Brownfields assessment activities.

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
Groundwater sample analytical results for remaining temporary monitoring wells identified low
level chlorinated solvent impacts in the northwestern portion of the Site (TW-7) where
redevelopment is not planned at this time. The chlorinated compounds TCE (2.8 µg/L) and vinyl
chloride (0.95 J µg/L) were detected at concentrations above their respective DEQ Residential
Vapor Intrusion GWSLs. In addition, a low level of PCE was detected in a groundwater sample
(TW-2) collected in the east-central portion of the Site at a concentration below the DEQ
Residential Vapor Intrusion GWSL. No other organic compounds were detected at
concentrations exceeding the regulatory screening criteria in the groundwater samples.
Exterior Soil Gas Sampling
To address the potential for structural vapor intrusion into proposed Site buildings, H&H
completed exterior soil gas assessment activities within the footprint of proposed buildings in the
southwestern portion of the Site. Note that the proposed redevelopment plan has changed since
completion of the 2019 Brownfields assessment activities.
Four exterior soil gas points (SG-1 through SG-4) were installed in the southwestern portion of
the Site to identify potential constituents that may pose a potential vapor intrusion risk
(Figure 3). Results of four soil gas samples identified benzene in two (2) soil gas samples (SG-1
and SG-2) at concentrations above the DEQ Residential Vapor Intrusion Soil Gas Screening
Level (SGSL). No other VOCs were detected at levels above the DEQ Vapor Intrusion SGSLs,
including TCE and related chlorinated compounds.
1.4 Vapor Intrusion Risk Evaluation
The DEQ Vapor Intrusion Screening Levels are conservative and based upon a Target Cancer
Risk (TCR) of 1 x 10-6 for potential carcinogenic effects and a Target Hazard Quotient (THQ) of
0.2 for potential non-carcinogenic effects. Vapor intrusion mitigation or additional assessment is
not typically warranted if the calculated cumulative lifetime incremental carcinogenic risk
(LICR) is 1 x 10-4 or less and the acceptable level for non-carcinogenic risk is a calculated
cumulative hazard index (HI) of 1.0 or less.

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
H&H utilized the DEQ Risk Calculator (January 2023) for residential land use scenarios to
further evaluate potential cumulative risks for structural vapor intrusion based on results of soil
gas samples collected at the Site. Risk calculator results for soil gas samples indicate that under
a hypothetical worst-case scenario for the soil gas to indoor air vapor intrusion pathway the
cumulative LICR is 2.5 x 10-6 and the cumulative HI is 0.20, which are below the unacceptable
risk thresholds. Copies of the completed DEQ Risk Calculators are provided in Appendix B.
Based on review of the laboratory analytical data and risk evaluation results, potential structural
vapor intrusion for the proposed apartment building can be managed through installation of
passive vapor intrusion mitigation system during construction of the proposed residential
building. Additionally, installation of the VIMS is anticipated to satisfy the Land Use
Restriction (LUR) 15.g., which generally states that no enclosed building may be constructed on
the Brownfields property until DEQ determines that the building is or would be protective of the
building’s users, public health, and the environment from risk of vapor intrusion.
S2K Charlotte plans to install a passive VIMS during construction of the proposed residential
building. The VIMS described herein has been designed with the capability to be converted to
an active sub-slab depressurization system with electrically driven fans, if warranted based on
results of post-installation VIMS efficacy sampling.

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 included in the
Notice of Brownfields Property recorded for the Site. 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 NCDEQ 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 detailed herein is designed to mitigate and minimize
potential intrusion of subsurface vapors into the subject buildings 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 is fully protective of public health
from known Brownfields property contaminants.

2.0 Design Basis

The VIMS design drawings for the proposed multifamily apartment development are included in
Appendix A. The following VIMS design sheets and will be used to guide construction of the
VIMS:
 Sheet VM-1 and VM-2 shows the VIMS layout on the ground floor levels (Level 1 and
Level 2);
 Sheet VM-3 shows the VIMS layout on the roof; and
 Sheets VM-A, VM-B, VM-C, and VM-D include section details and specifications.

Results of assessment activities completed at the Site did not identify potential structural vapor
intrusion risks at unacceptable levels. To further reduce the potential for structural vapor
intrusion at unacceptable levels, the VIMS will operate as passive sub-slab venting systems that
include a network of horizontal sub-slab and vertical above-slab riser piping that will discharge
vapors collected below the slab above the building roofline.

The proposed seven-story high-density apartment building will consist of a total enclosed
occupiable ground floor space of approximately 49,000 square feet (sq ft) which will be split into
two levels (Level 1 and Level 2). The ground floor spaces are proposed to include living spaces,
amenity areas, a leasing office, a courtyard, and a parking garage. The upper levels of the
building surrounding the courtyard and parking deck are proposed to consist of residential units
with a terrace on the seventh level.

The current development plans do not contain proposed commercial spaces or pour-back spaces
in the building. The residential building is proposed to be constructed with column-supported
post-tensioned (PT) slab-on-grade as depicted on the VIMS design drawings, with select portions
of the building containing thickened slabs below load-bearing walls. Note that it is not
recommended that additional monitoring points be added, or other holes be drilled through the
slab after tightening of the PT slab tendons.

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
On Level 1, the VIMS has been divided into three separately treated VIMS areas to the west,
east, and south of a mechanically-vented and partially open-air parking garage. The far western
and northwestern space of Level 1 (Area 1A) will contain mechanical and utility rooms, a trash
room, and a dog washroom. The remainder of the western portion of Level 1 (Area 1B) is
separated from Area 1A by a structural footer and will consist of residential living space that
encompasses an open-air courtyard.

The eastern portion of Level 1 (Area 1C) will contain a leasing office/amenity/lobby area and
bike storage room. Area 1D consists only of Stair B, which is located in the southwest corner of
the parking deck and is connected to the VIMS in Level 2. The mechanically vented and
partially open-air parking garage contains a single utility room. Although this room does not
contain living space above it, is not expected to be regularly occupied, and is separated from
Area 1C by a slab step, out of an abundance of caution, the utility room will be constructed with
a vapor barrier.

The southern half of Level 2 (Area 2) is slab-on-grade and will contain a VIMS. Area 2 consists
of residential living spaces, a fitness center, entertainment rooms, and amenity areas. Living
space is located on the floors above Level 1 and Level 2. The remaining areas of Level 2 above
Level 1 are proposed to contain living and amenity space. There are vertical retaining walls
proposed between the ground floor sections of Level 1 and Level 2. Occupiable ground-level
components of the proposed apartment building are further summarized in the table below.

Residential Building Ground Floor Use
VIMS
Area Level Description Ground Floor
Approx. Area (sq ft)
Area 1A Level 1 Utility and Non-Living Space 3,360
Area 1B Level 1 Living Space 18,100
Area 1C Level 1 Amenity Areas and Leasing 1,820
Area 1D Level 1 Stair B 240
Area 2 Level 2 Living Space and Amenities 19,500

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
The courtyard and parking garage extend through all seven stories of the building and are
enclosed by living spaces on Level 2 through Level 7. The parking deck is open to outside air on
Level 1 and Level 7 and is mechanically vented on each level through vent shafts located on the
far northwest and southeast corners of the parking deck. Additionally, the building will contain a
flat roof with some mechanical equipment.

The building also contains a total of four elevators that terminate on the top floor. Three
elevators begin on Level 1, and one begins on Level 2. No elevators open directly to the parking
garage. Additionally, there are three staircases in the building that start on Level 1 and terminate
on the top floor. Stair C is part of Area 1A and opens to the building exterior and to the living
spaces of Area 1B. Stair A is part of Area 1C and does not open to the parking garage until
Level 2. Stair B (Area 1D) is located on Level 1 and opens to parking on each floor and living
space beginning on Level 2.

2.1 Base Course Layer and Vapor Barrier

The VIMS includes placement of a minimum 4-inch base course stone (gravel) layer consisting
of high permeability stone below the concrete slab of the building (washed #57 stone, or similar
high permeability stone approved by the VIMS design engineer certifying the VIMP [design
engineer]). A vapor barrier (a.k.a., vapor liner) will be installed above the base course stone
layer and directly beneath the slab. The vapor barrier will also be installed underneath and along
vertical walls within elevator pits and on vertical sub-grade retaining walls backfilled with soil
that are located adjacent to enclosed or occupiable interior spaces. The specified vapor barrier
and waterproofing materials in these areas will be evaluated for compatibility. A horizontal
collection pipe network will be installed within the base course stone layer below the ground
floor slabs prior to placement of the vapor barrier. The horizontal vapor collection piping is
discussed further in Section 2.2 below. The piping layouts are shown on the VIMS design
drawings (Appendix A).

The vapor liner will consist of a VOC-rated vapor barrier such as Vaporblock® Plus 20 (VBP20)
manufactured by Viaflex, Inc. (Viaflex) or Drago® Wrap Vapor Intrusion Barrier (Drago Wrap)

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
manufactured by Stego® Industries (Stego). Vapor barriers will be installed per manufacturer
installation instructions. Technical specifications for the vapor liner products listed above are
included in Appendix C. Note that an equivalent VOC-rated vapor barrier, if approved by the
design engineer, may be used by the installation contractor. If an alternate equivalent vapor
barrier is selected for use, DEQ will be notified in writing, and specification and installation
instruction sheets will be provided.

The vapor barriers will be installed over the base course stone layer or applicable vertical sub-
grade walls and footers to cover the areas shown on the design sheets. Each vapor barrier
manufacturer recommends specific sealing agents (mastics, tapes, etc.) for their vapor barrier
product. In accordance with manufacturer installation instructions, alternative vapor barrier
products that are not approved by the manufacturers for sealing should not be used, unless
approved by the design engineer and specific manufacturer.

The exterior edges of the vapor barrier will be attached and sealed to building footings and
subsurface concrete features utilizing the tape specified in the manufacturer instructions. Seams
within the building envelope will have a minimum of 6 inches or 12 inches of overlap
(depending on the vapor barrier manufacturing specifications) and will be sealed with the tape
specified in the manufacturer instructions. If the vapor liner is damaged, torn, or punctured
during installation, a patch will be installed by overlaying a piece of vapor liner that is cut to the
approximate shape of the damaged area, and sized such that a minimum of 6-inches of patch
surrounds the damaged area. The seams of the patch will then be sealed using the manufacturer
recommended tape.

In areas where utility penetrations (i.e., piping, ducts, etc.) are present and the use of the tape
recommended by the manufacturer is not practical or deemed as “ineffective” by the design
engineer certifying the VIMP, an alternative sealant product specified by the vapor barrier
manufacturer can be used, such as Viaflex Pour-N-Seal™ or other low to no VOC containing
manufacturer-approved mastics. Following successful installation of the vapor barrier, the
finished concrete slab will be placed directly on top of the sealed vapor barrier to further seal the
seams and penetrations.

2.2 Horizontal Collection Piping and Vertical Riser Piping

Passive sub-slab venting will be accomplished using horizontal slotted or perforated collection
piping, which will collect vapor from beneath the ground floor slabs and discharge the vapors
above the building roofline through solid vertical exhaust piping. Sub-slab piping will consist of
3-inch diameter Schedule 40 (SCH 40) PVC piping and above-slab piping will consist of either
3-inch or 4-inch diameter SCH 40 PVC piping and fittings unless otherwise specified in the
design drawings (Appendix A). Solid sections of VIMS piping shall maintain a minimum of 1%
slope toward slotted sections to drain potential condensation water. Product specifications for
the sub-slab collection piping are provided in Appendix C.

As an alternative to 3-inch diameter SCH 40 PVC horizontal piping, soil gas collector mat
manufactured by Radon Professional Discount Supply (Radon PDS) may be used for sub-slab
vapor collection piping. The Radon PDS soil gas collector mat is a polystyrene, plastic,
rectangular conduit with a geotextile fabric covering. The mat is 1 inch thick and 12 inches wide
and is specifically designed for collecting soil gas from below a building. If used, the soil gas
collector mat will be connected to the proposed 3-inch diameter vertical risers and footing
crossings using Radon PDS-manufactured riser connection fittings. In lieu of the soil gas
collector mat extending unprotected through concrete, solid PVC pipe will be used as a soil gas
collector mat conduit in locations of footings and thickened slab crossings. Product
specifications for the soil gas collector mat are provided in Appendix C.

The vertical riser pipes will terminate above the roofline. While a passive system can effectively
operate without rooftop ventilators, to further enhance the passive VIMS, Empire Model
SV04SS (stainless steel) wind-driven syphon ventilators (or design engineer-approved
alternative) will be installed on the discharge end of the 3-inch or 4-inch SCH 40 PVC vertical
riser piping above the building roofline to further promote air exhaust from the risers. The
ventilators will generally be located on areas of the roof that receive effects from wind under
normal weather conditions. However, as the ventilators are intended to enhance the passive
VIMS and are not required for function of the system, some ventilators may be positioned in
areas that receive intermittent effects from wind based on the building layout and other building
16

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
components. The requirements for the discharge location based on distances to building
materials, operable openings, air intakes, etc. will be followed as indicated in the design
drawings and applicable building code.

To aid in identification of the vapor intrusion mitigation piping, the piping will be labeled by the
Site contractors with stickers adhered to a smooth surface or permanent labels which read,
“Vapor Mitigation – Contact Maintenance”, or similar language, on accessible piping at intervals
of no greater than 10 linear feet. Similar labels will also be affixed near the exhaust discharge on
the roof. VIMS labeling will be inspected by H&H prior to covering risers or building
occupancy.

Exhaust discharge locations must be a minimum of 2 ft above the roofline and a minimum 10 ft
from an operable opening (e.g., door or window) or air intake into the building. Note that the
exhaust locations on the roof depicted in the VIMS design may be repositioned within the
requirements specified above and pending approval by the design engineer certifying the VIMP.
Product specifications for the proposed turbine ventilators are provided in Appendix C.
Electrical junction boxes (120VAC, min 15-amp required) will be installed on the roof in close
proximity to riser exhaust discharges should connection to an electrical (active) fan be warranted
in the future.

2.3 Monitoring Points

Monitoring points constructed with 2-inch diameter SCH 40 PVC will be installed as part of the
VIMS to conduct effectiveness testing (see Section 4.0), including vacuum influence
measurements, and for the collection of sub-slab soil gas samples for laboratory analysis. Three
temporary monitoring points (TMP1-1 through TMP1-3) will be installed on Level 1 of the
building and one temporary monitoring point (TMP2-1) will be installed on Level 2. The
temporary monitoring points will be abandoned following successful influence testing and/or
sampling as discussed in Section 4.1. The temporary points will be abandoned by removing the
pipe to the extent possible, filling in the hole with an air-tight sealant (such as Viaflex Pour N
Seal), then patching the concrete to match the surrounding area. The monitoring point locations
are shown on the VIMS design drawings (Appendix A).
17

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
In general, monitoring points are placed at remotely distant locations from vertical riser piping
locations and in representative areas of the ground floor enclosed areas. To limit disturbance to
occupants during future monitoring events, the majority of the monitoring point access ports will
be located in stairwells, mechanical rooms, amenity spaces, or exterior-mounted locations. Each
monitoring point access port will be protected by a floor clean-out cover, wall access panel, or a
locking exterior waterproof wall enclosure. Several monitoring points will be connected to
extended sub-slab horizontal pipes which place the intakes of the monitoring points below
occupied spaces. The extended monitoring points are expected to have no more than
approximately 6 ft of extension pipe. Product specifications for the proposed floor cleanout
covers are provided in Appendix C.

In the event that a monitoring point cannot be installed due to building component conflict or is
damaged/destroyed during construction, a replacement monitoring point can be constructed,
pending approval by the design engineer certifying the VIMP. The replacement point(s) shall
consist of one of the specified designs in the design drawings. DEQ will be notified in advance
if monitoring points are relocated significantly in relation to approved locations specified in the
VIMP (i.e., if moved to a location in a different mitigation area, section of slab, or tenant area).
The specific types and locations of monitoring points installed will be documented in as-built
drawings provided in a VIMS installation completion report.

2.4 General Installation Criteria

The installed VIMS components (e.g., vapor barrier, piping, monitoring points, etc.) shall be
protected by the installation contractor and sub-contractors throughout the project. Protective
measures (e.g., flagging, protective boards, etc.) shall be used as needed to prevent damage to the
VIMS components. For example, the monitoring points and riser duct piping should be capped
with a removable slip-cap or cover immediately following installation to prevent water and/or
debris from entering the VIMS, and vapor barrier shall be protected from punctures and tears
during work completed following placement and sealing of the liners.

For each phase of construction (above and below slab), construction contractors and sub-
contractors shall use “low or no VOC” products and materials, when possible. This applies to all
18

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
building products and materials and not only those directly related to the VIMS. Furthermore,
the construction contractors shall not use products containing the compounds PCE or TCE. Prior
to submittal of a VIMS installation completion report, the construction contractor and sub-
contractors shall be directed to provide safety data sheets (SDSs) for all products and materials
used during construction. SDSs provided by the contractor and subcontractors will be included
in the VIMS installation completion report.

Utility Trench Dam Evaluation
Results of previous Site assessment activities did not identify the presence of chlorinated
solvents (such as TCE) in proximity to the proposed building at concentrations above laboratory
detection limits. In addition, Site-wide worst-case soil gas to indoor air vapor intrusion risk
calculations are within acceptable levels for cumulative carcinogenic and noncarcinogenic risks.
Also note that the generic sub-slab soil gas to indoor air attenuation factor that is the basis for
DEQ risk calculation is conservative and is intended to estimate a potential upper-bound indoor
air concentration accounting for temporal variability. In addition, the sub-slab soil gas to indoor
air attenuation factors do not account for a VIMS with a vapor barrier and sub-slab
depressurization that will greatly reduce the potential for unacceptable vapor intrusion risks.

As noted above, chlorinated solvents such as TCE were not detected at concentrations above
laboratory detection limits in soil, soil gas, and groundwater samples collected near the proposed
building footprint. The groundwater samples that did contain TCE are located approximately
300 feet downgradient of the closet edge of the proposed building footprint and adjacent to Sugar
Creek (Figure 4). Currently, there are no utilities for the proposed building that transect the area
of known TCE impacts in groundwater. Therefore, utility trench dams that are sometimes
installed to minimize lateral migration of vapors from an area of elevated concentrations to areas
beneath a building footprint are not warranted or practical based on the known contaminant
levels, locations of proposed utilities, and footprint of the proposed apartment building.

3.0 Quality Assurance / Quality Control

For quality assurance and quality control (QA/QC) purposes, inspections will be conducted
during each phase of VIMS installation. The components that require inspection are outlined
below:
(1) Inspection of vapor barrier along the sub-grade elevator pits and applicable vertical
retaining walls prior to backfilling;
(2) Inspection of the base course stone layer, sub-slab piping layout, and monitoring points
prior to installing the vapor barrier;
(3) Inspection of the vapor barrier below slab areas prior to pouring concrete;
(4) Inspection of above-grade vertical riser piping; and
(5) Inspection of riser pipe connections, pipe exhaust, and ventilators.

Additional inspections will be conducted if the system(s) are activated to verify electric fans (if
installed) are functioning. Each inspection will be performed by, or under the direction of, the
design engineer certifying the VIMP. Inspections will be combined, when possible, depending
on construction sequencing and schedule. The inspections will include field logs and
photographs for each section of slab. To minimize potential preferential pathways through the
slab, contractors will not use hollow piping to support utilities in preparation for concrete pours.
Contractors will be instructed to remove hollow piping observed during the field inspections.
The contractor shall notify the engineer certifying the VIMP, or its designee, with a minimum
two-business day notice prior to a planned inspection, and H&H will provide a subsequent two-
business day notice to DEQ for the pending inspection.
20

concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
4.0 VIMS Effectiveness Testing

4.1 Influence Testing

Post-installation (pre-occupancy) influence testing will be conducted on each VIMS treatment
area to evaluate vacuum communication across the slab and confirm sufficient depressurization
can be obtained should electric fans be needed in the future. Influence testing will be conducted
for each treatment area following installation of the horizontal collection piping, placement of
the vapor barrier, and completion of concrete slab pours. A two-business day notice will be
provided to DEQ prior to each influence test.

For system influence testing, one or more vapor extraction fans will be attached directly to
vertical riser piping for the section of the slab being evaluated. Pressure differential will be
measured at extraction fan locations and sub-slab vacuum levels will be measured at each
monitoring point location. While even low level sub-slab vacuum measurements can indicate
influence below the slab, a pressure differential below the slab of at least 4 pascals
(approximately 0.016 inches of water column [in-WC]) at remote distances from riser location in
each VIMS treatment area will be considered sufficient evidence of adequate sub-slab VIMS
influence per evaluation by the design engineer certifying the VIMP. Vacuum influence testing
results will be included in the VIMS installation completion report. If the influence testing
results indicate that modifications to the VIMS are needed to achieve sufficient sub-slab
depressurization, H&H will notify DEQ of the modifications prior to submittal of a VIMS
installation completion report.

4.2 Pre-Occupancy Sub-Slab Soil Gas Sampling

Following VIMS installation and prior to occupancy of the building, seven (7) sub-slab soil gas
samples will be collected from select monitoring points on Level 1 and four (4) sub-slab soil gas
samples will be collected from the slab-on-grade area of Level 2 to evaluate sub-slab conditions
for compounds that may pose a potential structural vapor intrusion risk at unacceptable levels.
The sub-slab soil gas samples will be collected from locations generally representative of the
21

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
slab conditions. Sub-slab soil gas sample analytical results will be used to evaluate efficacy of
the VIMS and potential risks to future occupants of the building. The proposed sub-slab soil gas
samples for the Site building will be collected from:
 Area 1A: MP1-3
 Area 1B: MP1-5, MP1-7, MP1-6, MP1-9
 Area 1C: MP1-11, MP1-14
 Area 2: MP2-2, MP2-4, MP2-5, MP2-7

For laboratory QA/QC purposes, one duplicate sub-slab soil gas sample will be collected during
each sampling event using a laboratory-supplied “T” fitting which allows for the collection of
two sub-slab soil gas samples from one sample location simultaneously.

Prior to sample collection, leak tests will be performed at each sub-slab soil gas sample location.
A shroud will be constructed around the monitoring point and sub-slab soil gas sampling train
and sample canister. Air within the shroud will be flooded with helium gas, and helium
concentrations will be measured and maintained using a calibrated helium gas detector. With
helium concentrations within the shroud maintained, sub-slab soil gas will be purged from the
sampling point with an air pump and collected into a Tedlar bag. The calibrated helium gas
detector will be used to measure helium concentrations within the Tedlar bag sample to confirm
concentrations are less than 10% of the concentration maintained within the shroud. A minimum
of three sample train volumes will be purged from each point prior to and during the leak testing
activities.

The sub-slab soil gas samples will be collected over an approximate 10-minute period using
laboratory supplied batch certified Summa canisters and laboratory supplied flow regulators
calibrated with an approximate flow rate of 100 milliliters per minute. The vacuum in the
Summa canisters will be measured at the start and end of the sampling event and will be
recorded by sampling personnel. The vacuum in each canister at the conclusion of the sampling
event shall remain above 0 inches of mercury (inHg), with a target vacuum of approximately
5 inHg. H&H understands that analytical results for a sample will not be accepted by DEQ if
internal vacuum in a canister reaches 0 inHg.
22

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
The samples will be submitted to a qualified laboratory under standard chain of custody
protocols for analysis of full-list VOCs by EPA Method TO-15. The analytical laboratory will
be instructed to report sample canister vacuum measurements as received at the laboratory and
laboratory estimated compound concentrations above the laboratory method detection limit, but
below the laboratory reporting limits (i.e., J-flag concentrations). In addition, H&H will request
that the laboratory report compound concentrations to the lower of the laboratory method
detection limits or to the extent possible, the DEQ Residential Vapor Intrusion SGSLs.

Upon receipt of the sub-slab soil gas sample analytical results, H&H will use the most current
version of the DEQ Risk Calculator to evaluate cumulative risks of potential vapor intrusion for
a residential use scenario. If calculated cumulative risks are greater than 1x10-4 for potential
carcinogenic risks and/or above a hazard index of 1.0 for potential non-carcinogenic risks, indoor
air sampling will be completed.

The DEQ DWM VI Guidance indicates that if sub-slab soil gas concentrations do not exceed
acceptable risk levels, typically no further investigation is necessary. However, as a very
conservative approach, if the chlorinated solvent TCE is detected at a concentration above the
laboratory reporting limits in a sub-slab soil gas sample, or if PCE is detected in the sub-slab soil
gas samples above its Residential Vapor Intrusion SGSL, indoor air sampling will also be
conducted as described below.

4.3 Indoor Air Sampling (If Warranted)

Pre-occupancy indoor air sampling co-located with the sub-slab soil gas samples listed above is
not anticipated for pre-occupancy sampling due to chlorinated solvents (including TCE) not
being detected above laboratory detection limits in soil gas samples collected at the Site, Site-
wide worst-case soil gas vapor intrusion risk calculations being well under the acceptable limits,
and no detection of chlorinated solvents in groundwater or soil sample collected in close
proximity of the proposed building footprint. If indoor air sampling is warranted based on
results of VIMS efficacy sub-slab soil gas sampling, indoor air sampling will be completed as
described in this section.
23

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
The building is intended to be occupied shortly following installation and operation of the
HVAC systems. Therefore, the indoor air sampling events (if warranted) will be conducted
following complete installation of the VIMS and after the building and/or sample area has been
fully enclosed. When possible, the indoor air sampling will be completed a minimum of two
weeks with operational ventilators but may be conducted prior to operation of the HVAC
system(s). The DEQ DWM VI Guidance, indicates “higher indoor air concentrations might be
expected when a building is sealed up and the HVAC is not running”, and “worse case
conditions may also be considered when the building is closed up and the HVAC system is
running.” HVAC equipment is typically not operational until approximately a few weeks prior
to closing due to the timing of the Mecklenburg County approval for installation of natural gas
and electrical meters. Conducting indoor air sampling with the building enclosed, but prior to
HVAC operation, may allow for a more conservative indoor air sampling approach and will
allow for time to conduct the pre-occupancy sampling and reporting for DEQ review.

In addition, HVAC equipment is not operational until finishing activities including installation of
flooring, cabinets, sealants, paints, industrial cleaning, etc. are being conducted. Potential off
gassing of VOCs from building finishing materials and products can impact the indoor air
concentrations and make it more difficult to evaluate the potential for a completed vapor
intrusion pathway. To minimize the potential for false positive resultant from off gassing
building construction materials, sampling ahead of operational HVACs and finishing activities is
proposed if indoor air sampling is warranted. If indoor air sampling is warranted, the locations,
number of indoor air samples, and timing for the indoor air samples will be based on sub-slab
soil gas sampling analytical data and discussions between the design engineer and DEQ.

The indoor air samples will be collected using individually certified 6-liter stainless steel Summa
canisters connected to in-line flow controllers equipped with a vacuum gauge. The flow
controllers will be set by the laboratory to allow for sample collection over an approximately 24-
hour period in accordance with the DEQ DWM VI Guidance. The sample will be set so the
intake point is positioned approximately 5 ft above grade (typical breathing zone height). In
addition, during each indoor air sampling event, one duplicate sample will be collected for
laboratory QA/QC and one background ambient air sample will be collected from a location
24
https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
upwind of the building, as determined by conditions on the day of the sampling event. Prior to
and after the indoor and background air samples are collected, vacuum in the canisters will be
measured using a laboratory-supplied vacuum gauge and recorded by sampling personnel. A
vacuum above 0 inHg and ideally around 5 inHg will be maintained within the canisters at the
conclusion of the sampling event.
The starting and ending vacuum in each canister will be recorded on the sample chain of
custody. Periodic checks will be conducted by sampling personnel to monitor the pressure
within the Summa canisters during sampling to ensure adequate sample volume is collected. The
sample canisters will then be labeled and shipped under standard chain of custody protocols to a
qualified laboratory for analysis of select VOCs by EPA Method TO-15. The select compound
list will be based upon the compounds detected in sub-slab soil gas samples and previously
identified Site contaminants of concern (COCs). The analytical laboratory will be instructed to
report canister vacuum measurements at receipt and J-flag compound concentrations. The
laboratory will be requested to report compound concentrations to the lower of the laboratory
detection limits or to the extent possible, the DEQ Residential Vapor Intrusion Indoor Air
Screening Levels (IASLs). In addition, an Indoor Air Building Survey form (Appendix C of the
DWM VI Guidance) will be completed for each sampling event by sampling personnel.
New construction materials such as treated lumber, paint, caulk, carpet, adhesives, sealants etc.,
which could be sources of VOCs in indoor air, may cause interference with Site-specific
compounds of concern during indoor air sampling. As previously noted, the construction
contractors and sub-contractors will be requested to provide SDSs for materials used during
construction which will be submitted to DEQ, if needed to further evaluate sub-slab soil gas and
indoor air sample data.
4.4 VIMS Effectiveness Results
Following receipt of analytical results, the laboratory analytical report will be reviewed and DEQ
will be notified in the event that TCE concentrations in sub-slab soil gas indicate potential vapor
intrusion pathways may exist. If subsequent indoor air sampling is warranted, in accordance
25

https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/s2k charlotte/metromont
concrete facility/vimp/rev. 1/to deq/22040 - vapor intrusion mitigation plan_metromont concrete facility_rev. 1.doc
with the DEQ DWM TCE Indoor Air Inhalation Immediate Action Levels and Response
guidance (dated July 2019), DEQ will be notified within 24 hours if TCE is detected at a
concentration exceeding 2.1 µg/m3 in indoor air based on the residential use of the building.
Note that no residents will be living in the building during post-construction indoor air sampling.

DEQ will also be notified prior to report submittal if sub-slab soil gas and indoor air sample
results indicate a completed vapor intrusion pathway. The results and analysis of the sub-slab
soil gas sampling (and indoor air sampling, if warranted) will be submitted to DEQ with the
VIMS installation completion report. After receipt of the sub-slab soil gas and/or indoor air
sample analytical results, H&H will use the most recent version of the DEQ Risk Calculator to
evaluate cumulative vapor intrusion risks under a residential use scenario.

H&H will consider the VIMS effective if the calculated cumulative risks for the sub-slab soil gas
and/or indoor air samples are within acceptable levels in accordance with DEQ Risk Calculator
results. The DEQ acceptable risk levels include:
 cumulative carcinogenic risks less than 1x10-4; and
 non-carcinogenic risk levels below a HI of 1.0.

In the event that calculated cumulative risks are greater than the acceptable risks listed above,
then an evaluation of potential interference of compounds from building material off gassing will
be conducted, and the data will be presented to DEQ. If it is determined that the sub-slab soil
gas concentrations are from Site contaminants and could lead to unacceptable vapor intrusion
risks to the occupants of the building, confirmation sub-slab soil gas and/or indoor air samples
may be collected from the area(s) of concern. Further, in this case, an evaluation to potentially
convert the system to an active VIMS or other enhancements to the system will be conducted. If
warranted, modifications to the VIMS will be presented to DEQ for review and approval prior to
implementation.

5.0 VIMS Effectiveness Monitoring

The VIMS is proposed as a passive system which will include vapor extraction through sub-slab
collection piping and solid exhaust risers that discharge sub-slab vapors above the roofline. The
passive system will be enhanced with wind-turbine ventilators to promote air exhaust from the
sub-slab. As such, differential pressure monitoring is not anticipated. If the VIMS is converted
to an active system based on pre-occupancy or post-occupancy sub-slab soil gas assessment
results, proposed modifications to the VIMP including modifying the VIMS design, testing and
analytical sampling requirements, and details for long-term differential pressure monitoring
across the slab will be submitted to the DEQ Brownfields Redevelopment Section in the VIMS
installation completion report and supporting as-built drawings. The specific electric fans to be
used will be selected by the VIMS design engineer based on the results of the influence testing
discussed in Section 4.0.

Post-occupancy sub-slab soil gas is proposed to be performed on a semi-annual basis for a
minimum of two years (four total events) following initial occupancy of the Site building. The
frequency, amount, and locations of the sub-slab (and indoor air samples, if applicable) for the
post-occupancy sampling events may be reduced or modified depending on the pre-occupancy
sampling results, pending DEQ review and approval. A recommendation regarding the post-
occupancy sampling will be provided in the VIMS installation completion report based on the
pre-occupancy sampling results and risk calculations.

The post-occupancy sampling will be conducted using the procedures described in this VIMP.
Further, after each post-occupancy semi-annual sampling event, if the sampling results indicate
consistent or decreasing concentrations within acceptable risk levels, a request to modify or
terminate sampling may be submitted for DEQ approval. No changes to the sampling frequency
or termination of sampling will be implemented until written approval is obtained from DEQ.

6.0 Future Tenants & Building Uses

The future use of the proposed Site building includes multifamily residential apartments. After
occupancy of the Site building, VIMS maintenance and upkeep will be the responsibility of the
building owner or property management group. If vapor mitigation components are damaged or
need to be altered for building renovations, the building owners or management will contact a
North Carolina licensed Professional Engineer (NC PE) to oversee or inspect the modifications
or repair activities, and a report will be prepared and submitted to DEQ detailing the repairs or
alterations.

To aid in identification of the vapor mitigation piping, the construction contractor will label the
pipe with “Vapor Mitigation – Contact Maintenance”, or similar language, on accessible piping
at intervals of no greater than 10 linear feet. The labels shall include a printed label or painted
label with stencils adhered directly to the pipe. Similar labels will also be affixed near the
exhaust discharge on the roof.

As part of the standard annual Land Use Restriction Update submittal required as part of the
Brownfields Agreement for the Site, the building owner or property management group should
complete a visual inspection of the exposed parts of the system including, but not limited to, the
vertical risers and ventilators on the roof and the monitoring points. Annual inspections are
recommended to be documented and kept on record to be provided to DEQ upon request.

7.0 Reporting
A VIMS Installation Completion Report (sealed by a NC PE) documenting installation, vacuum
pilot testing, and efficacy sampling activities associated with the VIMS will be submitted to
DEQ with a request for written compliance approval following confirmation that the mitigation
systems are installed and effectively mitigating potential vapor intrusion risks to building
occupants. The report will include a summary of VIMS installation activities such as
representative photographs and as-built drawings, QA/QC measures, SDSs of materials used in
construction, VIMS effectiveness testing results, and inspection documents. The report will also
include a statement by the design engineer as to whether the VIMS was installed in accordance
with the DEQ approved VIMP and is protective of public health as evidenced by the VIMS
inspections performed by the engineer or its designee, results of the influence testing, results of
the analytical testing, and QA/QC measures as described in this VIMP. Deviations from the
approved design will be provided in the report.
The Notice of Brownfields Property agreement for the Site includes standard land use
restrictions that indicate the building(s) shall not be occupied until DEQ provides written
compliance approval for the installation and performance of the VIMS as documented in the
installation report. However, as it has done in the past, DEQ may provide conditional approval
with submittal of a data summary package in lieu of the full VIMS Installation Completion
Report if warranted based on timing of the proposed building occupancy date and report review
times. No occupancy of the building will occur without prior written approval of DEQ.
After each semi-annual post-occupancy sub-slab soil gas sampling event, a report will be
submitted to DEQ to document the sampling activities and results with recommendations for
future post-occupancy sampling. The first post-occupancy semi-annual monitoring event is
anticipated to be conducted approximately six (6) months after the initial occupancy of the
building, or as otherwise approved by DEQ based on the results and timing of the occupancy of
the Site buildings.

PRODUCT DESCRIPTION
VaporBlock® Plus™ is a seven-layer co-extruded barrier
made using high quality virgin-grade polyethylene and
EVOH resins to provide unmatched impact strength as well
as superior resistance to gas and moisture transmission.
VaporBlock® Plus™ 20 is more than 100 times less permeable
than typical high-performance polyethylene vapor retarders
against Methane, Radon, and other harmful VOCs. Tested and
verified for unsurpassed protection against BTEX, HS, TCE, PCE,
methane, radon, other toxic chemicals and odors.
VaporBlock® Plus™ 20 multi-layer gas barrier is manufactured
with the latest EVOH barrier technology to mitigate hazardous
vapor intrusion from damaging indoor air quality, and the safety
and health of building occupants. VBP20 is one of the most
effective underslab gas barriers in the building industry today
far exceeding ASTM E-1745 (Plastic Water Vapor Retarders
Used in Contact with Soil or Granular Fill Under Concrete Slabs)
Class A, B and C requirements. Available in a 20 (Class A) mil
thicknesses designed to meet the most stringent requirements.
VaporBlock® Plus™ 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.

VAPORBLOCK® PLUS™ PLACEMENT
1.1. Level and tamp or roll granular base as specified. A base for a gas-reduction system may require a 4” to 6” gas permeable layer of clean coarse aggregate as specified by your architectural or structural drawings after installation of the recommended gas collection system. In this situation, a cushion layer consisting of a non-woven geotextile fabric placed directly under VaporBlock® Plus™ will help protect the barrier from damage due to possible sharp coarse aggregate.
1.2. Unroll VaporBlock® Plus™ running the longest dimension parallel with the direction of the pour and pull open all folds to full width. (Fig. 1)
1.3. Lap VaporBlock® Plus™ over the footings and seal with Raven Butyl Seal tape at the footing-wall connection. Prime concrete surfaces, when necessary, and assure they are dry and clean prior to applying Raven Butyl Seal Tape. Apply even and firm pressure with a rubber roller. Overlap joints a minimum of 6” and seal overlap with 4” VaporSeal™ Tape. When used as a gas barrier, overlap joints a minimum of 12” and seal in-between overlap with an optional 2-sided Raven Butyl Seal Tape. Then seal with 4” VaporSeal™ Tape centered on the overlap seam. (Fig. 2)

1.4. Seal around all plumbing, conduit, support columns or other penetrations that come through the VaporBlock® Plus™ membrane.
1.4a. Method 1: Pipes four inches or smaller can be sealed with Raven VaporBoot Plus preformed pipe boots. VaporBoot Plus preformed pipe boots are formed in steps for 1”, 2”, 3” and 4” PVC pipe or IPS size and are sold in units of 12 per box (Fig. 3 & 5).
Pipe boots may also be fabricated from excess VaporBlock® Plus™ membrane (Fig. 4 & 6) and sealed with VaporBoot Tape or VaporSeal™ Tape (sold separately).
1.4b. Method 2: To fabricate pipe boots from VaporBlock® Plus™ excess material (see Fig. 4 & 6 for A-F):
A) Cut a square large enough to overlap 12” in all directions.
B) Mark where to cut opening on the center of the square and cut four to eight slices about 3/8” less than the diameter of the pipe.
C) Force the square over the pipe leaving the tightly stretched cut area around the bottom of the pipe with approximately a 1/2” of the boot material running vertically up the pipe. (no more than a 1/2” of stretched boot material is recommended)
D) Once boot is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in between the two layers. Secure boot down firmly over the membrane taking care not to have any large folds or creases.
E) Use VaporBoot Tape or VaporSeal™ Tape to secure the boot to the
pipe.
VaporBoot Tape (option) – fold tape in half lengthwise, remove half of the release liner and wrap around the pipe allowing 1” extra for overlap sealing. Peel off the second half of the release liner and work the tape outward gradually forming a complete seal.
VaporSeal™ Tape (option) - Tape completely around pipe overlapping the VaporBlock® Plus™ square to create a tight seal against the pipe.
F) Complete the process by taping over the boot perimeter edge with VaporSeal™ Tape to create a monolithic membrane between the surface of the slab and gas/moisture sources below and at the slab perimeter. (Fig. 4 & 6)

of penetrations.
B) Mark where to cut openings and cut four to eight slices about
3/8” less than the diameter of the penetration for each.
C) Force patch material over penetration to achieve a tight fit and
form a lip.
D) Once patch is positioned, seal the perimeter to the membrane
by applying 2-sided Raven Butyl Seal Tape in-between the two
layers. (Fig. 8)
E) After applying Raven Butyl Seal Tape between the patch and
membrane, tape around each of the penetrations and the patch
with VaporSeal™ 4” tape. (Fig. 9) For additional protection apply

1.6. POUR-N-SEAL™ method of sealing side-by-side multiple penetrations (option 2);
A) Install the vapor barrier as closely as possible to pipe penetrations to minimize the amount of POUR-N-SEAL™ necessary to seal around all penetrations.
B) Once barrier is in place, remove soil or other particles with a dry cloth or a fine broom to allow for improved adhesion to the POUR-N-SEAL™ liquid.
C) Create a dam around the penetration area approximately 2” away from the pipe or other vertical penetrations by removing the release liner from the back of a 1” weather stripping foam and adhere to the vapor barrier. Form a complete circle to contain the POUR-N-SEAL™ materials (Fig. 11).
D) Once mixed, pour contents around the pipe penetrations. If needed, a brush or a flat wooden stick can be used to direct the sealant completely around penetrations creating a complete seal (Fig. 12-13).
E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longer than the time it takes to pour sealant.

Option 2
VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired prior
to placing concrete. When patching small holes, simply cut a 12” long
piece of 12” wide VaporSeal™ tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® Plus™ around pipe penetrations,
vertical columns, electrical ducts and other obstructions, you will
find it necessary to cut it to the nearest outside edge. This cut can
be easily sealed with 12” wide VaporSeal™ tape, by simply centering
it over the cut, 6” on either side. Once the tape is placed correctly,
apply pressure to assure a complete seal (Fig. 16).
Reminder Note: All holes or penetrations through the membrane will need
to be patched with 12” VaporSeal™ Tape.
Fig. 14
Page 4 of 5
Fig. 15
2.1. When installing reinforcing steel and utilities, in addition to the
placement of concrete, take precaution to protect VaporBlock®
Plus™. Carelessness during installation can damage the most
puncture–resistant membrane. Sheets of plywood cushioned with
geotextile fabric temporarily placed on VaporBlock® Plus™ provide
for additional protection in high traffic areas including concrete
buggies.
2.2. Use only brick-type or chair-type reinforcing bar supports to protect
VaporBlock® Plus™ from puncture.
2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be
avoided, each individual hole must be repaired per section 1.7.
2.4. To avoid penetrating VaporBlock® Plus™ when installing screed
supports, utilize non-penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® Plus™. If this cannot be avoided, each individual hole
must be repaired per figures 14-15.
2.5. If a cushion or blotter layer is required in the design between
VaporBlock® Plus™ and the slab, additional care should be given if
sharp crushed rock is used. Washed rock will provide less chance of
damage during placement. Care must be taken to protect blotter layer
from precipitation before concrete is placed.

DRAGO® WRAP
VAPOR INTRUSION BARRIER
Engineered protection to create a healthy built environment.
2.Unroll Drago Wrap over the area where the slab is to be placed.
Drago Wrap should completely cover the concrete placement
area. All joints/seams should be overlapped a minimum of
12 inches and taped using Drago® Tape. (Fig. 1). If additional
protection is needed, install DragoTack™ Tape in between the
overlapped seam in combination with Drago Tape on top of the
seam.
NOTE: The area of adhesion should be free from dust, dirt, moisture,
and frost to allow maximum adhesion of the pressure-sensitive tape. Ensure that all seams are taped with applied pressure to allow for
maximum and continuous adhesion of the pressure-sensitive Drago Tape. Adhesives should be installed above 40°F. In temperatures
below 40°F, take extra care to remove moisture/frost from the area
of adhesion.
3.ASTM E1643 requires sealing the perimeter of the slab. Extend
vapor retarder over footings and seal to foundation wall or
grade beam at an elevation consistent with the top of the slab
or terminate at impediments such as waterstops or dowels.
Consult the structural and environmental engineer of record
before proceeding.
IMPORTANT: Please read these installation instructions completely, prior to beginning any Drago Wrap installation. The following installation
instructions are generally based on ASTM E1643 – Standard Practice for Selection, Design, Installation, and Inspection of Water Vapor Retarders
Used in Contact with Earth or Granular Fill Under Concrete Slabs. There are specific instructions in this document that go beyond what is stated in
ASTM E1643 to take into account vapor intrusion mitigation. If project specifications call for compliance with ASTM E1643, then be sure to review
the specific installation sections outlined in the standard along with the techniques referenced in these instructions.

MULTIPLE PIPE PENETRATION SEALING: (Fig. 5)
NOTE: Multiple pipe penetrations in close proximity may be most efficiently sealed using Drago Wrap, Drago
Sealant, and Drago Sealant Form for ease of installation.
a. Cut a hole in Drago Wrap such that the membrane fits over and around the base of the pipes as closely as
possible, ensuring that it is flush with the base of the penetrations.
b. Install Drago Sealant Form continuously around the entire perimeter of the group of penetrations and at least
1 inch beyond the terminating edge of Drago Wrap.
c. Pour Drago Sealant inside of Drago Sealant Form to create a seal around the penetrations.
d. If the void space between Drago Wrap and the penetrations is not minimized and/or the base course allows for
too much drainage of sealant, a second coat of Drago Sealant may need to be poured after the first application
has cured.
IMPORTANT: AN INSTALLATION COMPLETED PER THESE INSTRUCTIONS SHOULD CREATE A MONOLITHIC MEMBRANE
BETWEEN ALL INTERIOR INTRUSION PATHWAYS AND VAPOR SOURCES BELOW THE SLAB AS WELL AS AT THE SLAB
PERIMETER. THE UNDERLYING SUBBASE SHOULD NOT BE VISIBLE IN ANY AREA WHERE CONCRETE WILL BE PLACED. IF
REQUIRED BY THE DESIGN ENGINEER, ADDITIONAL INSTALLATION VALIDATION CAN BE DONE THROUGH SMOKE TESTING.
Stego Industries* recommends the use of BEAST vapor barrier-safe concrete accessories, to help eliminate the use of non-permanent penetrations in Drago Wrap installations.

THE WORLD’S CHOICE FOR SOIL GASES FOR THREE DECADES!2
SOIL GAS COLLECTOR MAT FOR
RADON READY NEW CONSTRUCTION
According to the US EPA’s model standards for radon control systems in new building construction, a means for collecting soil gas should be installed beneath the slab.
More and more mitigators and buildiers are using PDS’ soil gas collector mat (SGC Mat) because its installation does not entail any special coordination with plumbers or other site contractors. Low profile mat saves time as it removes the need for trenching. Just lay radon mat down around the inside perime-ter of the foundation, secure it with spikes or land-scaping staples, and pour the concrete.
SGC mat is superior to other mat systems because of its thickness and it has a geotextile fabric cloth surrounding the entire mat material. This feature eliminates the need to lay a plastic barrier or sheet on top of the mat to protect the matrix. Using plastic sheeting can cause concrete cracking due to differential dewatering. The full fabric design greatly enhances both the installation as well as the quali-ty of the concrete slab. When SGC mat is installed below the slab, you’re providing an airspace that in-tercepts radon--and other soil gases and vapors--be-fore it seeps into the building through the slab. SGC mat also works well as a soil gas collector beneath crawlspace barrier due to its low-profile.
WHY AND HOW IT WORKSThe matting is a one inch high by twelve inch wide matrix enveloped in a geotextile filter fabric. 90% of the geomatrix is airspace, which means soil gas has room to move to the collection point. This creates incredible pressure field extension for post construc-tion system activation. The mat can support con-crete without compressing, yet is extremely light-weight and easy to handle.
This system allows for radon to flow through the filter fabric and into the airspace. The airspace does not clog because the filter fabric retains the under-lying gravel and soil. The natural airflow through the mat then channels the radon to the T riser to pipe connection. From there, hazardous gas can be vent-ed safely through the roof of the building.
Another key element of a soil gas collection system is attaching the 4” riser* ( 3” and 6” options avail-able) to the mat, such that airflow is not restricted at this critical juncture. The soil gas T riser is unique as it has three ports, two redundant mat entries and one PVC connection to outside air. This unique fitting connects all three sides without special con-nections or fittings. Use SGC Seam Tape to ensure air tight splices and corners.

INSTALLATION INSTRUCTIONS*
Begin work on the sub grade (soil, sand, or gravel) after the final preparation and before the concrete is poured. Start with T-Riser(s) and work out to en-sure smooth mat placement. Position the T-Riser(s) in appropriate location(s) and secure with nails or staples.
Slide mat into flat openings on either end of T-ris-er with a portion of the fabric around the outside. Tape the fabric to the outside of the T-Riser with duct tape and staple mat to the ground with land-scape staples to ensure soil contact remains during pour stage.
Mat is typically laid out in a rectangular loop in the largest area with branches or legs into smaller areas (FREE takesoffs at www.radonmat.com). There is no need to trench the mat. Roll out the SGC mat and smooth it onto the ground. To avoid wrinkles and buckling, work away from the risers, stapling to the ground as you go. The mat should be stapled every three to four feet, in addition to corners, tee junctions & ends.
Corners are constructed by peeling back the filter fabric, cutting two ends of the matrix at 45 degree angles, and butting (or overlapping: no more than 1/2”) the matrix together. Pull the filter fabric back and tape into place. Staple across the joint of the matrix and each leg of the corner. Use a minimum of four staples at each corner-- two across the joint and one on each leg.
The tees for branches and legs are constructed by slitting the fabric of the main loop at the location desired. Cut the fabric of the branch at the edges and expose two inces of the matrix. Cut off the exposed matrix and but the matrix of the branch (or overlap 1/2”)to the matrix of the main loop. Pull the filter fabric of the branch back over the main loop and tape into place. Staple across joint of the matrix with two staples and one each on the branch and main loop. Use a minimum of four staples at each tee, two across the joint and one on each loop and branch.

INSTALLATION INSTRUCTIONS
All openings in the fabric at joints, T’s, and ends of branches should be taped to keep out concrete.
Stub up a few feet of 4” schedule 40 PVC** from all T risers before pour. Seal with caulk and screws. This ensures no concrete aggregate enters the ris-er during slab pour. Be sure to label “CAUTION RADON REDUCTION SYSTEM” on all pipe. **(6” PVC may be substituted--for large multifamily proj-ects. Simply cut T riser 4” insert away to reveal 6” Legacy T Riser). PVC sizes vary by code and design. 3”, 4”, & 6” schedule 40 PVC are acceptable.
When the building is ready for the vent pipe to be installed above the slab, fit to pre-stubbed PVC with PVC straight connect. Always label “CAUTION RADON REDUCTION SYSTEM” every 10 feet to avoid confusion on site and for the building occupants.
STEP SIX
STEP SEVEN
STEP EIGHT
NOTE: The openings in the riser are laid out at 180 degrees to accomodate straight runs of mat. However, if the riser is to be placed in a corner, which is not uncommon, the front of the T can be cut and the SGC mat inserted into the new opening. The side of the T that is unused should be sealed with tape. This creates a 90 degree T which will allow corner placement for the riser. Mat should al-ways enter the T riser from at least two directions and exhaust to pipe vertically.

*These are the manufacturer’s instructions to ensure a proper functioning system. Certain code variants across the US have more lax or more con-
servative requirements. PDS’ soil gas collector can be installed to meet any code requirement (as of publication of this document). Please reach out
to PDS or a certified radon mitigator for consulting on specific code variants.

MAKING CORNERS
AND SPLICES
The geotextile mat should be routed around the inside perimeter of the foundation. This will require occasional corner junctions. Furthermore, splices will have to be made to join two lengths of mat to-gether. Corners and splices are very easy to make, and do not require any special fittings. Cut back the filter fabric to reveal the core material.
In the case of a splice, merely overlap the core by at least one corrugation, replace the cloth, and tape it using PDS SGC seam tape. Use two landscape staples to hold the splice in place. In the case of a corner, peel back geotextile fabric and slice the core of the two adjoining legs at 45 degree angles which mirror each other; overlap the edges by one corrugation; return grey geotextile fabric, tape, and staple the corner together.
7RADONPDS.COM | 719-444-0646 | [e-mail]
CONNECTING THE MAT
TO THE T RISER
A convenient T-riser with dual entry allows for ei-ther end of the loop of mat to be secured to the riser. Slide the mat into each end of the riser and tape the edge to prevent wet concrete from enter-ing. Cap the riser to ensure no concrete enters. T Riser caps can be purchased in lieu of duct tape. A prestub of PVC pipe can also serve the same pur-pose. See steps 8-9 above.
***Due to high product demand, several T riser de-signs have been tested and approved for sale. Your riser may look different than the one pictured here, however its function is the same. Ensure you stub up the PVC pipe and seal all openings with tape so that concrete does not enter during the pour. Secure mat to the ground with staples so riser doesnot float.

The filter fabric that comes sewn around the soil gas collector prevents the wet concrete from entering the mat and reducing its air collection capacity. The only precaution that needs to be taken is that the fabric is taped closed at seams of splices and corner to sufficiently keep the uncured concrete from entering.
The mat also needs to be secured to the soil with landscape staples to prevent the concrete from lifting off the soil while it is being applied. Re-enforcing bars and wire can be laid on top of the mat.
Note: the mat is strong enough to withstand concrete workers and their wheel barrows.

1. Product NameModel SSK-08
2. ManufacturerStrong Sleeves™ LLC10 Town Plaza, #444Durango, CO 81301www.strongsleeves.com
3. Product DescriptionUses: Strong Sleeves™ are installed when forming concrete structural supports, creating a continuous path-way for effective soil gas collection systems. In accordance with the Drawings, the pre-manufactured Strong Sleeve devices allow radon mitigation mats to easily be continued through concrete grade beams and con-crete stem walls without transitioning to round pipe.Advantages: Strong Sleeves are designed and engineered for safer construction of new residential, commer-cial, and school buildings by eliminating extensive trenching and specialized gravel fill materials.
4. Installation a. Install at elevations and locations shown on the Drawings or as otherwise directed by the Archi tect. Coordinate all locations with the Structural Engineer to confirm that the block-out locations through the grade beams and stem walls have sufficient structural strength and adequate reinforce ment. b. Attach the Sleeve to the interior walls of the concrete forms using the (4) pre-drilled holes in each Sleeve unit. Adjust steel reinforcement as directed by the Structural Engineer for wall or grade beam penetrations. c. After pouring concrete and removing concrete forms, remove the foam insert within each Sleeve. Use mechanical means only, DO NOT USE SOLVENTS TO DISSOLVE THE FOAM. Using solvents (such as gasoline) to remove the foam blocking may damage radon mitigation equipment and may lead to the risk of fire.
5. Availability and CostStrong Sleeves™ are available through our network of specialty radon supply distributors. For current cost information and availability contact Radon PDSwww.radonpds.com.

** Hot Smoke SealTM fire tested: Listed to meet the requirements of standards UL10B, UL10C, UBC 7-2, Part 1 and BS476: 1987 for application to fire rated door assemblies. Tested for smoke controlled assemblies: Listed to meet the requirements of standards UL1784, NFPA 105, UBC 7-2, Part 2, and BS476:Part 31, Section 31.1:1983.
It also is a chemically inert, highly stable, expandable graphite strip, tested and proven in positive pressure conditions to withstand both hot smoke and hot gasses, resulting in the longer integrity of a door assembly. More economical to use than specially modified doors in “tested assembly only” classifications. Chemically inert, and therefore will not degrade from carbon dioxide and ozone like the many intumescents being offered by other manufacturers.
Hot Smoke Seal™ is not affected by moisture and will not break down like fiber or cellulose based products and does not require periodic after market field inspections.
Insulation: is a rigid mineral wool (stone wool) insulation board for high temperature industrial applications subject to light mechanical loads.] - 2” thickness.
