Vapor Intrusion Mitigation Plan Building 2 - North Rite Aid Facility 1776 Statesville Ave Charlotte, North Carolina
Brownfields Project No. 20050-16-060 H&H Job No. ATL-001
1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for
installation of a vapor intrusion mitigation system (VIMS) within the northern portion of Building
2 on the Rite Facility Brownfields Property located at 1776 Statesville Avenue, in Charlotte,
Mecklenburg County (Site). The Brownfields Site is approximately 47.87 acres and is comprised
of three contiguous parcels of land (Mecklenburg PIN #s 07903102, 07903105, and 07903103).
The Site entered into a Brownfields Agreement with the North Carolina Department of
Environmental Quality Brownfields (DEQ Brownfields) Program on November 2, 2010
(Brownfields Project No. 20050-16-060) dated October 2017. Soil and groundwater are
contaminated at the Brownfields Site due to historical operations and activities. The US Army
Corps of Engineers (Corps), on behalf of the US Department of Defense (DOD) is working with
DEQ to address impacts release to historical operations conducted at the Site including
manufacturing of Model T Ford automobiles, a storage depot for the US Government, and for
production of Hercules missiles for the military.

The Protective Developer (PD) is Camp Landowner, LP, and the development is known as Camp
North End. The Camp North End Building 2 project address is listed as 201 Camp Road and 701
Keswick Avenue. Building 2 (previously referred to as Building 1 during Brownfields activities,
and Corps Building 5) is located in the eastern-central portion of the Site as depicted on Figure 1
and is currently unoccupied. The Building 2 designation for this building is used throughout this
VIMP.

S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
The building is comprised of a warehouse style structure with an existing concrete slab and brick
walls. Building 2 is proposed to be retrofitted for commercial and retail use, and is not proposed
to contain residential units.

This VIMP document includes the following sections:

• a brief summary of previous vapor intrusion assessment activities completed at the Site
(Section 2.0),
• a description of the proposed VIMS (Section 3.0),
• quality assurance/quality control (QA/QC) procedures that will be implemented during
installation of the VIMS (Section 4.0),
• post-installation/pre-occupancy testing that will be conducted to confirm the effectiveness
of the VIMS (Sections 5.0 and 6.0),
• a discussion about future tenant uses (Section 7.0), and
• reporting activities (Section 8.0).

This VIMP was prepared in accordance with the DEQ Division of Waste Management (DWM)
Vapor Intrusion Guidance (VI Guidance) dated March 2018 and the Brownfields Program Vapor
Intrusion Mitigation System Design Submittal New Construction Minimum Requirements
Checklist which is included as Appendix H in the VI Guidance.

2.0 Summary of Previous Vapor Intrusion Assessment

H&H completed sub-slab soil vapor (SSV) and indoor air (IA) sampling activities at the Site in
2016. The SSV sampling results are summarized in the H&H Phase I and II Environmental Site
Assessment report dated August 16, 2016, and the indoor air sampling results are summarized in
the H&H Indoor Air Assessment report dated, November 9, 2016. A brief summary of the SSV
and IA sampling results for Building 2 (formerly identified as Building 1 during the assessment
activities) is described below.

3
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
In April 2016, H&H installed three soil-gas monitoring points (SGMPs), SSV-4 through SSV-6,
in Building 2. Analytical results indicated that trichloroethylene (TCE) was detected above the
NC DEQ Non-Residential Sub-Slab Soil Gas Screening Levels (SGSLs) in SSV-4 (34,000 µg/m3)
and SSV-5 (3,000,000 µg/m3) collected in the northern portion of Building 2. In addition,
tetrachloroethylene (PCE) was detected above its residential SGSLs and chloroform was detected
above its non-residential SGSLs in sample SSV-5.

Based on the results of the SSV sampling, H&H conducted IA sampling activities in Building 2 in
June 2016. H&H collected a total of six indoor air samples (IAS-1 through IAS-6) in the northern
portion of Building 2. The indoor air samples were analyzed for PCE, TCE, and their degradation
products, and chloroform. Note, acrolein was also included as an analyte for the IA samples
because previous IA sampling conducted by Hoffman Engineering, Inc. (on behalf of Rite Aid in
2008) reported acrolein at concentrations above the DWM Indoor Air Screening Levels (IASLs).
In September 2016, additional IA samples (IAS-22 and IAS-23) were collected from the southern
portion of Building 2 after a temporary vapor wall barrier (comprised of plastic sheeting and
drywall) was installed between the northern side and southern side of Building 2. The purpose of
the temporary vapor wall barrier was to prevent air exchange between the northern and southern
portions of Building 2, and thus isolate each area prior to and during the sampling event.

The analytical data from the IA samples indicated that TCE was detected above the Non-
Residential IASL in samples IAS-2 through IAS-5 located in the northern portion of Building 2.
TCE was detected above its Residential IASL in sample IAS-1, collected from the northernmost
section of Building 2, and IAS-6, collected from the southern portion of Building 2. However,
TCE was not detected above the Residential IASL in samples IAS-22 and IAS-23, collected from
the southern portion of Building 2 after installation of the temporary vapor wall barrier. Acrolein
was detected above its Non-Residential IASL in each sample, but was also detected in the
background samples. In addition, acrolein was not detected in the previous SSV samples from
Building 2 and is also a common by-product of petroleum and tobacco combustion. Therefore, it
is unlikely that acrolein was a result of vapor intrusion from the sub-surface. DEQ issued a project
memorandum noting that acrolein was not considered an environmental impact from historical
4
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
operations at the Site. Excerpts included analytical data tables and sample location maps from the
previous assessment activities are included as Attachment A.

Based on the TCE detections in indoor air within the northern portion of Building 2, DEQ
determined that vapor intrusion mitigation controls are warranted for the northern area of Building
2. Based on the results of the indoor air sampling data, DEQ determined that vapor mitigation
controls are not warranted for the southern portion of the Building 2, located south of the previous
temporary vapor wall barrier.

The VIMS proposed in the northern portion of the Building 2 is described in the following sections
of this VIMP. Note, as part of the proposed construction plans for Building 2, a road extension,
identified as the Keswick Avenue extension (a.k.a. the “Keswick Cut”), will be constructed as an
open-air area through the central portion of Building 2 at a location immediately south of the of
the temporary vapor wall barrier. The section of Building 2 located north of the proposed Keswick
Avenue extension is referred to as Building 2 – North, and the area south of the road extension is
referred to as Building 2 – South. During construction of the Keswick Avenue extension, the
existing concrete slab in this area will be removed and new exterior walls along the street extension
will be constructed. Thus, the VIMS described in the following sections of this VIMP will be
installed in Building 2 – North and will terminate at the exterior wall along the road extension.

3.0 Design Basis

This VIMP consists of installation of an active VIMS at Building 2 – North to mitigate potential
vapor intrusion concerns from the sub-surface for non-residential use scenarios. The VIMP is
included as Sheets VM-1, VM-2, and VM-3 in Attachment B and will be used to guide construction
of the VIMS. Please note that H&H is providing the venting design on Sheets VM-1, VM-2, and
VM-3 in Attachment B, and Pontarolo Engineering, Inc. (Pontarolo), the design engineer for the
Cupolex® line of products, is providing the structural drawings for the contractor for the concrete
slab which is presented on Sheets C1, C2, and C3 in Attachment C. Prior to construction,
Pontarolo will provide final structural drawings to the construction contractor.

5
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
The proposed plans for Building 2 – North contain open-air pavilions and porches located outside
of the exterior building walls. These areas may contain a roof or cover, but will not be closed-in,
nor will they contain heating, ventilation, and air condition (HVAC) units or controls. The
locations of these open-air porches and pavilions are depicted on Sheet VM-1.

Installation of VIMS
The approximate area of Building 2 – North covered by the VIMS is approximately 101,000 square
feet (sq ft). The VIMS includes installation of a Cupolex® Windi H.5 (5cm) ventilated floor
system installed atop the existing concrete slab in Building 2. The Cupolex Windi system consists
of polypropylene Cupolex plastic dome-shaped concrete forms interlocking in a grid pattern with
a height of 5 cm, or approximately 2-inches. A 4-inch thick concrete slab will be poured above
the Cupolex system to create a floating slab-on-grade concrete floor system with an under-slab
void. Manufacturer specification sheets for the Cupolex system components are included in
Attachment C. The Cupolex system will be installed by the redevelopment contractor at the
direction of Cupolex Building Systems, a division of Pontarolo who will provide training for the
installation contractor and will perform limited inspections of the ventilated floor installation.
H&H will perform additional inspections of the VIMS during installation activities as discussed
further in Section 4.0.

As sections of the concrete slab are poured, penetrations (including, but not limited to expansion
joints, control joints, construction joints, isolation joints, open cracks in the Cupolex concrete floor
slab, plumbing and electrical conduits, venting system pipes, etc.) to the floor will be sealed using
a urethane caulk or grout per manufacturer installation recommendations to prevent movement of
air along the annulus between pipes, conduits, utility banks, or similar features. Details showing
typical sealing of vertical penetrations through the slab and Cupolex floor are included on Sheet
VM-2 in Attachment B. Please note that there are no elevator shafts or slab-steps (slab elevation
changes) proposed in Building 2 – North. Also, please note that exterior doorways and openings
are proposed to be retrofitted to account for the approximate 6-inch combined height of the
Cupolex and concrete floor. However, if a doorway is unable to be retrofitted due to structural or
architectural reasons, then a ramp at the doorway to the top of the new concrete floor slab may be
constructed per Detail 13 on Sheet VM-2.
6
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
Sealing Agents
The polyurethane caulk or grout used to seal the concrete floor slab penetrations shall be a low-
VOC containing product and will not contain TCE or PCE. The vapor barrier material for sealing
around ramps (if needed) or repairs in the Cupolex system will be Raven Industries 20-mil
VaporBlock Plus, or an equivalent product approved by the VIMP design engineer and DEQ
Brownfields. The appropriate vapor barrier sealing products (mastic/epoxy, tapes, etc.) associated
with the selected vapor barrier shall be used and installed per manufacturer recommendations.
Products used in the VIMS must be approved by the VIMS design engineer certifying the VIMP.
The Raven VaporBlock Plus specifications are included in Attachment D.

Tenant Walls
Note, Building 2 – North will contain multiple commercial tenants after construction. The tenants
may install stud walls located on the new concrete floor installed above the Cupolex system. The
stud walls are not proposed to extend through the concrete floor slab. In the event walls or utilities
are constructed through the new concrete floor slab and penetrate the Cupolex system, the
penetrations will be sealed and repaired per the details in Sheets VM-1 to VM-3. Repairs or
modifications that extend through the concrete floor and to the Cupolex system will be inspected
by a North Carolina (NC) Professional Engineer (PE) prior to completion. In addition, a report
documenting the repairs and modifications will be submitted to DEQ Brownfields upon
completion of the activities.

To the extent practical, attempts will be made to avoid the use of the primary contaminants of
concern in the building construction materials. At a minimum, the construction materials will not
contain PCE or TCE.

Vent Piping and Motorized-Fans
The VIMS will be installed as an active system designed to prevent potential vapors from
migrating into the building by sub-slab depressurization within the under-slab voids within the
Cupolex system. Vapors will be extracted from the sub-slab using 4-inch diameter polyvinyl
chloride (PVC) or 4-inch diameter cast-iron vent piping that will penetrate the concrete floor slab
and Cupolex and extend above the building’s roofline along existing interior columns or within
7
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
proposed stud walls. The riser pipes will be connected to an in-line electrical-powered extraction
fan installed on the building’s roof. H&H has proposed installation of Festa AMG Legend fans;
however, the fan type and size may be modified based on the results of the influence testing
(Section 5.0) to provide adequate sub-slab depressurization within the building. Alternative
electric fans must be approved by the design engineer certifying the VIMS, and DEQ Brownfields
will be notified of the change. The proposed locations of the vent riser pipes and details are
included on Sheets VM-1 and VM-2 in Attachment B.

The exhaust point of the vent pipe and fan will be located at least 3 ft above the building’s roofline,
and least 15 ft horizontally from HVAC intakes, areas where people congregate or traverse, and
other operable openings into the building. Additionally, the exposed vent piping will be labeled
with “Vapor Mitigation – Contact Maintenance Department” (or similar language) at intervals no
greater than 10-linear ft. along spans of the vent pipes. A label will also be affixed on or near the
fans with a unique fan identification number and with information similar to that on the pipe labels
as indicated above.

VIMS Alarm System
In accordance with the DWM VI Guidance, an alarm system is required for active VIMS to alert
the building maintenance staff should the extraction fan fail to operate as designed. An alarm
system will be installed that will consist of a telemetric monitoring system that will alert building
maintenance staff with email, text, and/or phone notifications if the fans fail to operate correctly.
The alarm system will contain a Sensaphone differential pressure sensor on each riser that will
communicate with a centralized computer that will be enabled with cellular or internet connection.
Specifications for the proposed alarm system, the Sensaphone Sentinel Monitoring System, are
included on Sheet VM-2 and specification sheets are included in Attachment D. The location to
house the Sensaphone Sentinel unit will be chosen by the architect/owner. Similar alternative
devices for the alarm system may be installed by the owner/installation contractor with the
approval of the VIMS design engineer certifying the VIMS. The final product specifications and
alarm system design details will be included in the as-built drawings and submitted to DEQ
Brownfields with the VIMS Installation Report.

S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
4.0 Quality Assurance / Quality Control

For quality assurance and quality control (QA/QC) purposes, inspections will be conducted during
various phases of VIMS installation activities. Inspections will be performed as follows:

• prior to installation of the Cupolex forms to observe installation activities associated with
utility trenches and penetrations,
• during installation of the Cupolex system, prior to slab-pours, and
• during installation of the exhaust vent piping and extraction fans.

Each inspection will be performed by, or under the direction of, the VIMS design engineer (NC
PE) certifying the VIMP. In addition, Cupolex Building Services will provide limited inspections
and site-specific training during installation of the Cupolex system for the installation contractor.
The inspections will include field logs and photographs for each portion of the VIMS. The
engineer certifying the report, or designee, will provide DEQ Brownfields with at least a 48-hour
notice prior to conducting inspections.

5.0 Post-Construction and Pre-Occupancy System Effectiveness Testing

Following installation of the Cupolex system and completion of the concrete floor slab, but prior
to building occupancy, influence pilot testing will be conducted to measure VIMS vacuum
communication below the slab. To conduct the proposed influence testing, variable speed vapor
extraction fans similar to the proposed electric fans (AMG Legend) will be attached to the exhaust
end of the sub-slab vent piping system. Vacuum and air flow will be measured at varying speeds
with measurements recorded at the extraction fan location to evaluate pressure differential between
indoor air and the Cupolex sub-slab void space. The proposed vacuum monitoring points are
shown on Sheet VM-1 and will consist of Vapor Pin® devices with secured covers that will be
installed after the new concrete slab is poured and set flush with the finished concrete floor surface.
Specification sheets and installation instructions for the Vapor Pin devices are provided in
Attachment E. Due to the interconnectedness and limited air resistance of the void space within
the Cupolex system, vacuum across the entire void space throughout the building are expected to
9
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
be similar. Therefore, the proposed monitoring points should be sufficient to provide
representative data of sub-slab vacuum measurements across the building.

Depressurization is considered sufficient if vacuum measurements meet or exceed 4 pascals
(approximately 0.016 inches of water column, inWC) at remote extents of the VIMS treatment
area per DEQ Brownfields requirements. Based on post-construction effectiveness testing, an
alternative fan (other than the proposed AMG Legend) may be selected by the design engineer to
meet the 4 pascals vacuum levels. If an alternative fan is selected, DEQ Brownfields will be
notified and the fan specifications will be included in the VIMS Installation Report.

Upon completion of the VIMS installation activities including activation of the permanent
extraction fans and when the condition of the building is similar to that of occupancy, vacuum
effectiveness testing will be performed by collecting pressure differential measurements at the
vacuum monitoring points described above to confirm that the permanent extraction fan effectively
depressurizes the sub-slab voids in the Cupolex system. Vacuum and air flow measurements will
also be measured at the extraction fan locations. Based on the layout of future commercial tenants,
some of the vacuum monitoring points may be inaccessible after future upfit activities. In these
cases, the specified monitoring points will be abandoned with an air-tight sealant and concrete and
new monitoring points will be installed in accessible areas within the building. DEQ Brownfields
will be notified of modifications to the monitoring point locations for review and approval prior to
performing the modifications.

As shown on VM-1, the VIMS has been designed to prevent potential vapor intrusion into the
proposed Site building using one interconnected Cupolex void space across the entire building
footprint. Due to the ability to maintain a high vacuum within the Cupolex void space, consistent
vacuum measurements of 4 pascals or greater is expected to provide an adequate measure of sub-
slab depressurization to prevent vapor intrusion into the building.

Indoor air analytical sampling will also be conducted to verify the VIMS effectiveness. Upon
completion of successful pilot testing and prior to occupancy of the building, an initial indoor air
sampling event (IAS Event No. 1) will be conducted. In addition, a confirmation indoor air
10
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
sampling event (IAS Event No. 2) will be completed approximately one year following IAS Event
No. 1. Based on results of IAS Event No. 1 and IAS Event No. 2, H&H will request DEQ
Brownfields provide written approval to discontinue confirmation indoor air sampling events.
After construction of the VIMS, only limited walls are anticipated to be installed within the
building space. Therefore, the majority of the building space will be interconnected the IAS
Events. A total of five indoor air samples are proposed to be collected during each event along
with one indoor air duplicate sample and one background air sample. The locations of the
proposed indoor air parent samples are depicted on Sheet VM-1.

The background and indoor air samples will be collected using individually-certified 6-liter
stainless steel Summa sample canisters connected to in-line flow controllers with a vacuum gauge.
The flow controllers will be set by the laboratory to allow the samples to be collected over an
approximately 8-hour period (commercial use scenario). A 3-foot long sampling cane will be
connected to the flow controller so that the sample intake point is positioned approximately 5 ft
above grade (typical breathing zone height) when the sample canister is set on its base. 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 will be maintained within each canister at the conclusion of the sampling event.

The starting and ending vacuum in each canister will be recorded on the sample chain-of-custody
form. In addition, vacuum measurements taken by the laboratory at the time of sample receipt will
be provided in the final laboratory report. Following sample collection, the Summa canisters will
be labeled and shipped under standard chain-of-custody procedures to a qualified laboratory for
analysis of select VOCs by EPA Method TO-15. The laboratory will be instructed to analyze for
only those compounds detected above the laboratory method detection limit in the previous indoor
air samples from the 2016 assessment, with the exception of acrolein which was determined to not
likely be a result of vapor intrusion (Section 2.0). The laboratory will be requested to use reporting
limits that are below DEQ DWM Non-Residential Vapor Intrusion Indoor Air Screening Levels
(IASLs). In addition, the laboratory will be requested to report compound concentrations above
the laboratory method detection limits, but below the laboratory reporting limits (i.e., J-Flags).

11
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
The analytical data will be compared to the DEQ DWM Non-Residential IASLs and entered in the
DEQ Risk Calculators. Reports documenting indoor air sampling activities will be submitted to
DEQ Brownfields within four to six weeks of completion of each sampling event. The analytical
data will be provided to DEQ Brownfields within two weeks of receipt and validation of the data.
Based upon the sampling results, H&H will make recommendations in accordance with the DWM
VI Guidance. It is anticipated that the recommendations will consist of one of the following:

• The VIMS is effective, and no further sampling of indoor air is warranted (per the DWM
VI Guidance, in the case where calculated cumulative risks are below 1x10-4 for potential
carcinogenic risks and below a hazard index of 1 for potential non-carcinogenic risks).

• Additional indoor air sampling is warranted to confirm that the VIMS is effective (per the
DWM VI Guidance, in the case where calculated cumulative risks are greater than 1x10-4
for potential carcinogenic risks or above a hazard index of 1 for potential non-carcinogenic
risks). Modifications to the active fans or other VIMS components may be conducted, if
required, and follow-up sampling will be performed after modification to the fans or VIMS.

6.0 Post-Occupancy Testing

Post-occupancy vacuum testing will be conducted to verify the VIMS is operating and continues
to effectively depressurize the sub-slab voids in the Cupolex system. For the first year of post-
occupancy operation, vacuum testing will be conducted on a quarterly basis and will be reported
to DEQ Brownfields on a quarterly basis. Post-occupancy vacuum measurement events will be
conducted using the Vapor Pin® devices similar to the pre-occupancy testing described above.
The VIMS will include a vacuum alarm system with telemetric alarm notifications that will
immediately notify the building maintenance department of loss of power or vacuum at the fans
and risers. Therefore, repairs or modifications to the system shall occur promptly to ensure proper
operation of the VIMS.

12
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
After the first year of post-occupancy operation, H&H will evaluate the quarterly vacuum testing
data collected over the first year with DEQ Brownfields to determine the frequency and reporting
requirements for future monitoring events. Modifications to the frequency of the vacuum
monitoring events will be submitted to DEQ Brownfields for approval prior to making changes to
the schedule or reporting requirements.

If vacuum measurements during testing do not meet or exceed 4 pascals (approximately 0.016-
inWC), H&H will evaluate the VIMS to determine the cause and identify potential repairs or
modifications to obtain the desired vacuum. Alteration or repair to the VIMS will be reported to
DEQ Brownfields.

7.0 Future Tenants & Building Uses

The building will be operated by a property management company with a maintenance staff that
will notify H&H (or another NC PE firm), of any potential exposure, damage, alteration, or repairs
to the VIMS. As previously discussed, the commercial retail spaces may not all be initially
occupied but the VIMS will be installed throughout the building prior to occupancy. The property
manager will inform future retail space tenants of the presence of the VIMS and request that they
notify them of any damage to the system during potential future renovation or upfit activities.
H&H (or another NC PE firm) will provide oversight and inspection of any work that may
potentially impact the VIMS and submit documentation of these activities to DEQ Brownfields.
8.0 Reporting

Following successful post-construction effectiveness testing, a NC PE-certified report
documenting installation of the VIMS (VIMS Installation Report) will be submitted to DEQ
Brownfields for review and compliance approval. The report will summarize VIMS installation
activities, QA/QC measures, post-construction and pre-occupancy system effectiveness testing
activities, and an opinion as to whether the VIMS was installed consistent with the design and
objective of the DEQ-approved VIMP. The report will include as-built construction figures, SDS
13
S:\AAA-Master Projects\ATCO LLC - ATC\ATL-001 - Rite Aid\Task-009 Brownfields\VIMS Design\Camp North End_Building 2 North_VIMP_071620.docx
sheets for products used in the VIMS and by the general contractor in the building, and inspection
reports from H&H and Pontarolo that include photographs and field logs.

Quarterly reports will be provided to DEQ Brownfields to document quarterly vacuum monitoring
for the first year following building occupancy. First year post-occupancy monitoring data will be
evaluated to determine appropriate frequency and reporting requirements for future vacuum
monitoring events. A request to reduce the number of future vacuum monitoring points must be
submitted to DEQ Brownfields for approval. In addition, a post-occupancy indoor air analytical
sampling will be conducted approximately one year after occupancy and reported to DEQ
Brownfields under separate cover. Reporting for vacuum monitoring events will be conducted
and reported under a licensed NC PE or NC Professional Geologist (PG) seal. If VIMS
modifications or repairs are needed or conducted, the NC PE will notify DEQ Brownfields and
provide documentation of activities conducted for DEQ Brownfields record.

Attachment C Cupolex® Specification Sheets and Structural Slab Design Sheets
CUPOLEX-WINDI® creates a ventilated floor in new or remodeled building without affecting the structure of the
building. The adoption of CUPOLEX- WINDI® allows you to save on waterproof sheathing and guarantees a
constant seal against dampness. CUPOLEX-WINDI® may also be easily attached to walls to obtain an air space
capable of ventilating and eliminating mold and installed to create ventilated flat or pitched roofs.

Concrete is poured over the modular forms to create floating or structural grade supported slabs, partially
supported or fully supported slabs on beam, piles or deep foundations. The unique concrete geometry Cupolex
creates, forms an under slab void that can be passively or mechanically vented to remove moisture and soil gases,
protecting buildings against the ingress of harmful soil gasses.
Applications
 Radon & Soil Gas (VI) Mitigation
 Basement subfloors
 Post tensioned reinforced Concrete Slabs
 Concrete Slab on Grade or basement slabs
 Replacing Gravel Drainage Layers
 Replacing Vapor Barriers & Liners
 Building Green With LEED
 Technical/Electrical Sub Floors
 Acoustical Floors
 Ventilating flat or pitched roofs
 Green Roofs
 Solution to provide a drainage layer on terraces and balconies.
Installation
CUPOLEX WINDI® provides Excellent Flexibility in Working with new construction or remodeled building
layouts. The main characteristics of the forming system are speed and simplicity; the following
points should be adhered to:

 On average two laborers set 110 m2/hr (1200 sf/hr)
 Layout complies with a grid system
 Can be installed on any resting surface - soil, gravel, mud slab, etc.
 Each CUPOLEX® Form has an installation arrow
 Forms are Installed by starting from left to right and top to bottom
 Ensure that the feet connection pins are correctly inserted into their connection holes
 Pouring and finishing of the concrete slab in the conventional manner

VAPORBLOCK® PLUS™VBP20
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.
PRODUCT USE
VaporBlock® Plus™ 20 resists gas and moisture migration
into the building envelop when properly installed to provide
protection from toxic/harmful chemicals. It can be installed as
part of a passive or active control system extending across the
entire building including floors, walls and crawl spaces. When
installed as a passive system it is recommended to also include
a ventilated system with sump(s) that could be converted to an
active control system with properly designed ventilation fans.
VaporBlock® Plus™ 20 works to protect your flooring and
other moisture-sensitive furnishings in the building’s interior
from moisture and water vapor migration, greatly reducing
condensation, mold and degradation.
SIZE & PACKAGING
VaporBlock® Plus™ 20 is available in 10’ x 150’ rolls to
maximize coverage. All rolls are folded on heavy-duty cores
for ease in handling and installation. Other custom sizes

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)

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.

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.

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.

Scope:
This standard operating procedure (SOP)
describes the methodology to use the VAPOR
PIN® Drilling Guide and Secure Cover to
install and secure a VAPOR PIN® in a flush
mount configuration.
Purpose:
The purpose of this SOP is to detail the
methodology for installing a VAPOR PIN®
and Secure Cover in a flush mount
configuration. The flush mount
configuration reduces the risk of damage to
the VAPOR PIN® by foot and vehicular traffic,
keeps dust and debris from falling into the
flush mount hole, and reduces the
opportunity for tampering. This SOP is an
optional process performed in conjunction
with the SOP entitled “Installation and
Extraction of the VAPOR PIN®”. However,
portions of this SOP should be performed
prior to installing the VAPOR PIN®.
Equipment Needed:
VAPOR PIN® Secure Cover (Figure 1);
VAPOR PIN® Drilling Guide (Figure 2);
Hammer drill;
1½-inch diameter hammer bit (Hilti™ TE-
YX 1½" x 23" #00293032 or equivalent);
5/8-inch diameter hammer bit (Hilti™ TE-
YX 5/8" x 22" #00226514 or equivalent);
assembled VAPOR PIN®;
#14 spanner wrench;
Wet/Dry vacuum with HEPA filter
(optional); and
personal protective equipment (PPE).

bit with tape will assist in this process.
4)Remove cuttings from the hole and place
the Drilling Guide in the hole with the
conical end down (Figure 3). The hole is
sufficiently deep if the flange of the
Drilling Guide lies flush with the surface
of the slab. Deepen the hole as
necessary, but avoid drilling more than 2
inches into the slab, as the threads on the
Secure Cover may not engage properly
with the threads on the VAPOR PIN®.
Figure 3. Testing Depth with the Drilling
Guide
5)When the 1½-inch diameter hole is
drilled to the proper depth, replace the
drill bit with a 5/8-inch diameter bit,
insert the bit through the Drilling Guide
(Figure 4), and drill through the slab. The
Drilling Guide will help to center the hole
for the VAPOR PIN®, and keep the hole
perpendicular to the slab.
6)Remove the bit and drilling guide, clean
the hole, and install the VAPOR PIN® in
accordance with the SOP “Installation and
Extraction of the VAPOR PIN®.
Figure 4. Using the Drilling Guide
7)Screw the Secure Cover onto the VAPOR
PIN® and tighten using a #14 spanner
wrench by rotating it clockwise (Figure 5).
Rotate the cover counter clockwise to
remove it for subsequent access.
