Dear Mr. Kanellis:
The North Carolina Department of Environmental Quality Brownfields Program (DEQ
Brownfields) received and reviewed the Vapor Intrusion Mitigation Plan (VIMP), dated August 3,
2020, and DEQ Brownfields has found this VIMP to be in compliance with Land Use Restriction
2.g.iii. of the Notice of Brownfields Property and DEQ approval of the VIMP was provided by
email on August 3, 2020.

Consistent with the Brownfields agreement for this project, an essential component of public health
protection for this design is the professional engineer’s seal of these documents that the proposed
design will be effective at mitigating the potential for vapor intrusion at the property and protecting
public health. Furthermore, the safe occupancy of the building will be evaluated upon “Post-
Construction and Pre-Occupancy System Effectiveness Testing” as required by Section 4.0 of the
VIMP. In addition, DEQ Brownfields reserves the authority to require confirmation of efficacy in
the future.

Please be advised that this design compliance review from DEQ Brownfields does not waive any
applicable requirement to obtain any necessary permits, licenses or certifications which may be
required from other state or local entities.

H&H Job No. LEH-004
1.0 Introduction

On behalf of LEH NC Mint, LLC (the Prospective Developer or PD), Hart & Hickman, PC (H&H)
has prepared this Vapor Intrusion Mitigation Plan (VIMP) for the Quality Products Co.
Brownfields property located at 1513, 1515, and 1521 S. Mint Street, Charlotte, Mecklenburg
County, North Carolina (Site). The Site is comprised of three tax parcels (Mecklenburg County
Parcel ID Nos. 11908315, 11908316, and 11908317) totaling approximately 0.53-acres and is
currently developed with a single-story multi-tenant commercial building with an associated
gravel-covered parking area.

Proposed redevelopment plans for the Site include upfit and renovations for adaptive re-use of the
existing building. The remainder of the Site will generally be covered with impervious surfaces
including parking areas, sidewalks and exterior patios. A preliminary redevelopment Site plan is
included in Attachment A.

H&H previously completed vapor intrusion assessment activities at the Site to evaluate the
potential for vapor intrusion prior to redevelopment. Results of previous vapor intrusion
assessment activities are documented in our Limited Phase II Environmental Site Assessment
(ESA) Report (dated March 2, 2018), and the Brownfields Assessment Report (dated October 22,
2019). Tabular summary of the vapor intrusion assessment sample results and sample location
maps are provided in Attachment B for ease of reference.

The North Carolina Department of Environmental Quality (DEQ) Brownfields Program has
requested the collection of sub-slab soil gas samples within the 1513-1515 S. Mint Street building

to establish pre-mitigation baseline concentrations of mercury vapors. As such, a work plan has
been included in Section 2.0 of this VIMP.

The draft Brownfields Agreement for the Site includes the following land use restriction (LUR)
No. 15.g.:

No enclosed building may be constructed on the Brownfields Property and no existing building,
defined as those depicted on the plat component of the Notice of Brownfields Property, may be
occupied until DEQ determines in writing that:
i. the building is or would be protection of the building’s users, public health and the
environment from risk of vapor intrusion based on site assessment data or a site-specific
risk assessment approved in writing by DEQ; or
ii. the building is or would be sufficiently distant from the Brownfields Property’s
groundwater and/or soil contamination based on assessment data approved in writing by
DEQ that the building’s users, public health and the environment will be protected from
risk from vapor intrusion related to said contamination; or
iii. vapor mitigation measures are installed or implemented to the satisfaction of a
professional engineer licensed in North Carolina, as evidenced by said engineer’s
profession seal on a report that includes photographs and a description of installation and
performance of said measures. Any design specification for vapor intrusion mitigation
measured shall be approved in writing by DEQ in advance of installation and/or
implementation of said measures. The design specifications shall include
methodology(ies) for demonstrating performance of said measures.

In accordance with the LUR No. 15.g., the DEQ Brownfields Program approved Environmental
Management Plan (EMP) dated October 29, 2019, and conversations with DEQ Brownfields
personnel in a meeting held on October 7, 2019, the PD has elected to install a vapor intrusion
mitigation system (VIMS) in the Site building.

H&H has prepared this VIMP includes installation of a passive VIMS to minimize potential vapor
intrusion into the Site building. The VIMP is described in the following sections and was designed

2.0 Baseline Mercury Sub-Slab Soil Gas Assessment

Two (2) sub-slab soil gas samples will be collected from each tenant space (1513 and 1515 S. Mint
Street) at similar locations to the previous sub-slab soil gas samples for a total of four (4) samples.
Samples will be collected using Cox Colvin Vapor Pin™ (Vapor Pin) kits. A leak check will be
performed on the sample point (Vapor Pin) annular seal prior to assembling the sample train and
sample collection. A shroud will be placed over the sample point, filled with helium gas, and a
helium gas detector will be used to maintain helium gas concentrations within the shroud. With
helium concentrations maintained within the shroud, sample points will be purged using a syringe
and disposable fittings to collect purged vapor into a Tedlar® bag. The purged soil gas will be
analyzed using the helium gas detector to ensure that helium concentrations in the sample are less
than 10% of the helium concentrations measured within the shroud.

Following a successful leak check, a sampling train will be assembled using Tygon® tubing with
an in-line lab provided sorbent tube filled with hopcalite. An air sampling pump and a flow meter
will be used to collect the sample through the sample train at a constant rate. The laboratory
recommended sample volume and flow rate will be used to achieve the required method detection
limits.

Due to the potential presence of background mercury in the sorbent media, two (2) field blanks
will be prepared during the sampling event. Field blanks will be prepared by opening the sample
media (sorbent tube) and sealing it without collection of soil gas through the media.

Following sample collection, the sample media will be shipped under standard chain-of-custody
protocols to a North Carolina certified laboratory for analysis of elemental mercury by the National
Institute for Occupational Safety and Health (NIOSH) Method 6009. Each sub-slab soil gas
sampling point will be abandoned and the surfaces will be restored to pre-drilling conditions.

3.0 Design Basis
The VIMS Design for the Site building is included as Attachment C (Sheets VM-1 and VM-2) and
will be used to guide construction of the system. The VIMS will operate as a passive system to
extract and discharge sub-slab vapors above the roofline using riser duct piping and wind-driven
turbine fans.

The Site building is single-story with masonry walls and concrete foundations. The southeast
portion of the 1513 S. Mint Street tenant space will be demolished and converted to outdoor space
(see Attachment A). The proposed finished ground floor area for the Site building is approximately
12,000 square feet.

H&H conducted pilot testing within the Site building and identified overall poor sub-slab
communication. Based on pilot testing activities, the PD has elected to remove the existing
concrete slab within the Site building for installation of the VIMS and a new monolithic concrete
slab-on-grade. Proposed renovations include new storefront doors and windows, removal of
existing columns, and alteration of the roof and foundation within the building. This includes the
removal of the existing interior masonry wall in the 1513 S. Mint Street portion of the Site building
and installation of new steel columns and concrete footings for supporting existing continuous
masonry walls and concrete foundations. In addition, existing slab elevation changes (ramps,
drainage slopes, etc.) will be removed during slab removal activities. Soil beneath the building
may need to be moved and reused on-Site or exported from the Site. Soil disturbed during
redevelopment activities will be managed in accordance with the DEQ-approved EMP dated
October 29, 2019.

The proposed future uses of the Site building following renovations will include multi-tenant
commercial use. However, the future tenants have not been confirmed at this time. Therefore,
portions of the concrete floor may not be finished immediately, and will be temporarily left as
pour-back areas to allow for future tenant utility installations as needed for the planned use.
Further discussion associated with potential future tenant uses and pour-back slab areas is provided
in Section 7.0.

Note that subsurface conditions at the Site, such as foundation components, have not been field
verified. Therefore, the VIMS Design is subject to change pending field verification. Deviation
from this VIMP requires engineer approval and DEQ will be notified as described herein. A
summary of the VIMS Design components is included in the following sections.
3.1 Base Course Layer and Vapor Barrier
The VIMS includes placement of a minimum 5-inch base course gravel layer consisting of high
permeability stone (clean #57 stone, or similar high permeability stone approved by the design
engineer) below the proposed new concrete slab. A vapor barrier will be installed above the base
course layer and beneath the concrete slab. The vapor barrier will consist of Vaporblock® Plus 20
(VBP20) manufactured by Raven Industries (Raven). VBP20 is an ASTM-certified 20-mil, multi-
layer, chemically resistant vapor barrier, designed to minimize the migration of volatile organic
compounds (VOCs). The VIMP specifies that the vapor barrier will be installed per manufacturer
installation instructions. Technical specifications and installation instructions obtained from
Raven for the VBP20 vapor barrier and associated accessories are provided as Attachment D.
To summarize the vapor barrier installation instructions, VBP20 will be installed by the
construction contractor to cover the base course layer below the slab area of the proposed ground
floor slab. The vapor barrier will be attached/sealed to concrete and masonry surfaces of footings
and existing walls (see Sheet VM-2). Two-sided butyl seal tape will be used to attach/seal the
vapor barrier to concrete or masonry surfaces. Seams within the building footprint will have a
minimum 12-inch overlap and will be sealed with VaporSeal™ tape. Small puncture holes will
be sealed with VaporSeal™ tape and/or Pour-N-Seal™. Larger holes, tears, or other damage will
be repaired using a patch of vapor barrier that overlaps the damaged area and then will be taped
along the seams. In areas where utility penetrations (i.e., piping, columns, ducts, etc.) are present
and the use of taping is not practical or is deemed “ineffective” by the design engineer, Pour-N-
Seal™ will be poured into a form to patch the penetration with a vapor tight seal.

Please note that an equivalent vapor barrier approved by the design engineer which meets the
criteria specified on Sheets VM-1 and VM-2 of the VIMP may also be used by the installation

contractor, such as Drago Wrap® manufactured by Stego Industries. If an alternate equivalent
vapor barrier is selected, DEQ will be notified.

3.2 Horizontal Collection Piping, Riser Duct Piping, and Turbine Fans
Passive sub-slab venting will be accomplished using wind-driven turbine fans and 4-inch diameter
horizontal collection piping which will collect vapor from beneath the floor slab for discharge
above the building roofline. Sub-slab piping will consist of 4-inch diameter Schedule 40 (SCH
40) PVC piping and fittings, and above-slab piping will consist of 4-inch cast-iron piping and
fittings. The piping layout is shown in Sheet VM-1, and cross-section details are shown in Sheet
VM-2 (Attachment C).

The VIMP includes Empire Model TV04SS (stainless steel) wind-driven turbine fans (or approved
alternative) installed on the discharge end of the riser duct piping on the roof. Discharge locations
must be a minimum of 2 ft above the roofline at the point the piping exits the roof and 10 ft from
an operable opening or air intake into the building. Note that fan locations on the rooftop depicted
in the VIMS Design may be repositioned within the requirements specified above and pending
design engineer approval. Product specifications for the proposed turbine fans and PVC vapor
collection piping are provided in Attachment D.

Solid sections of horizontal collection pipe shall be supported to prevent pipe sag or low point and
maintain 1% slope toward slotted sections to drain condensation. Above-slab accessible riser duct
piping will be permanently identified by means of a tag or stencil at a minimum of once every
10-linear ft with “Vapor System – Contact Owner”, or similar language. An electrical junction
box (120v, 60hz AC required) will be installed near each turbine fan location on the rooftop for
future connection of active electrical fans (if warranted).

As noted above and discussed further in Section 7.0, portions of the concrete floor slab may not
be completed and will be pour-back areas until future tenant sub-slab utility installation has been
completed. Therefore, controls such as wooden boards and/or decking will be used to protect the
vapor barrier from being punctured between installation and the slab placement.

3.3 Monitoring Points
Monitoring points will be constructed to allow collection of sub-slab soil gas samples using Vapor
Pin® devices manufactured by Cox-Colvin and Associates, Inc. Specification sheets and
installation instructions for the Vapor Pin® devices are provided in Attachment D. The proposed
layout of monitoring points is included in Sheet VM-1. The proposed monitoring point locations
are preliminary and are subject to change based on Site conditions, such as subsurface utilities and
accessibility. DEQ will be notified in advance if monitoring points are relocated significantly in
relation to approved locations specified in the VIMP (i.e., moved to a location in a different
mitigation area, section of slab, or tenant area). In general, monitoring points will be placed at
remotely distant locations from the riser duct piping.

Note that for each phase of construction (above and below slab), construction contractors and
sub-contractors shall use “low or no VOC” products and materials that could potentially contain
the compounds of concern associated with the Site. The construction contractor and sub-
contractors shall provide safety data sheets (SDSs) to the design engineer for products and
materials used during construction. SDSs provided by the contractor and sub-contractors will be
included in the VIMS Installation Completion Report.

4.0 Quality Assurance / Quality Control
For quality assurance and quality control (QA/QC) purposes, inspections will be conducted during
each phase of system installation activities. VIMS components that require inspection are outlined
below:
(1) Inspection of sub-slab piping layout prior to installing vapor barrier;
(2) Inspection of base course gravel layer prior to installing vapor barrier;
(3) Inspection of vapor barrier prior to pouring concrete;
(4) Inspection of above-grade riser duct piping; and
(5) Inspection of turbine fans and riser duct pipe connections.

Each inspection will be performed by, or under 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. As
requested, the engineer certifying the report, or designee, will provide DEQ with 48-hour notice
prior to conducting the inspections. Please note that 48-hrs notice to DEQ may not be possible in
all instances.

As discussed in this VIMP, portions of the concrete floor slab in each building may not be
completed (poured back) until future tenant sub-slab utility installation has been completed. As
such, H&H or a NC PE will inspect the VIMS before the slab is poured back following any work
conducted that may impact the VIMS. Documentation of these activities will be submitted to DEQ
upon final reporting.

Note that additional inspections will be conducted if the system is activated to verify that the
electric fans (if installed) are functioning properly.

5.0 Post-Installation System Effectiveness Testing

Post-installation influence testing will be conducted on the VIMS to evaluate sub-slab
communication and document sufficient depressurization can be obtained below the slab should
the system be activated with electric fans in the future (if warranted). Influence testing will be
conducted following installation of the horizontal collection piping, vapor barrier, and concrete
slab pours. Testing will be conducted when the riser duct piping is stubbed above the slab. Note
that influence testing may potentially be conducted while portions of the concrete slab have not
been completed, as discussed in Section 7.0.
For system effectiveness testing, one or more variable-speed vapor extraction fans will be attached
directly to riser duct piping. Pressure differentials will be measured at extraction fan locations and
monitoring points for the section of slab being evaluated. As noted above, the monitoring point
locations are included in Sheet VM-1 and VM-2 (Attachment C).

A pressure differential resulting in depressurization below the slab of at least 4 pascals
(approximately 0.016 inches WC) at remote distances from riser location of the VIMS is
considered sufficient. The results of the influence test will be submitted to DEQ with the VIMS
Installation Completion Report, unless the influence test reveals that modifications are needed to
the VIMS to achieve the required sub-slab depressurization. In this case, the test results will be
provided to DEQ prior to the VIMS Installation Completion Report to facilitate VIMS repairs or
modifications, as needed.

Sub-Slab Soil Gas Sampling
Upon completion of successful influence testing and following completion of successful VIMS
installation, sub-slab soil gas samples will be collected from select monitoring points to further
evaluate efficacy of the VIMS. Two (2) sub-slab soil gas samples will be collected from each
tenant space (1513 and 1515 S. Mint Street) for a total of four (4) sub-slab soil gas samples.
Samples will be collected a minimum of two weeks following successful VIMS installation and
installation of the vapor barrier within pour-back areas. Based on initial sub-slab soil gas efficacy
sampling results and pending DEQ-approval, subsequent sub-slab soil gas sampling events will be
reduced to one (1) sub-slab soil gas sample from each tenant space for a total of two (2) samples.

Note that depending on baseline mercury sub-slab soil gas assessment (Section 2.0), additional
sub-slab soil gas mercury analysis may be required. If additional mercury analysis is required, the
same sampling procedures outlined in Section 2.0 will be implemented.

The monitoring points will be sampled in general accordance with DWM VI Guidance by
attaching Teflon sample tubing to the barbed end of the Vapor Pins. During each sub-slab soil gas
sampling event a duplicate sub-slab soil gas sample will be collected for QA/QC purposes. The
duplicate sample will be collected from one of the monitoring points using a laboratory supplied
stainless-steel “T sampler” fitting which allows for collection of two sub-slab soil gas samples
from a single monitoring point simultaneously.

Prior to sample collection, leak tests will be performed for each monitoring point sample location.
To leak test the annular seal between the monitoring point and the floor slab, a shroud will be
placed around the monitoring point and sampling train, the air within the shroud will be flooded
with helium gas, then sub-slab soil gas will be purged from the sampling point with an air pump
and collected into a Tedlar bag. A helium gas detector will be used to measure helium
concentrations within in the shroud and in the Tedlar bag sample. The annular seal leak test will
be considered successful if the helium concentration measured within the Tedlar bag sample is less
than 10% of the concentration measured in the shroud.

To leak test the fittings in the sampling train, a shut-in test will be performed in addition to the
helium leak test. To complete the shut-in test, valves will be used to seal the fittings where the
sampling train connects to the sub-slab soil gas point and the Summa canister. A vacuum will then
be applied to the sampling train using either a vacuum pump or a syringe. After a minimum
vacuum of 10 inches of water is achieved, a vacuum gauge on the sampling train will be observed
for at least 30 seconds to ensure the pressure remains unchanged. If an observable loss in vacuum
is noted, the leak test will be considered unsuccessful. If the helium or shut-in leak tests are
unsuccessful, measures will be taken to identify and address the source of the leak and additional
leak testing will be performed. In total, a minimum of 3 sample train volumes will be purged from
the point prior to and during the leak testing activities.

The sub-slab samples will be collected using laboratory supplied 1-liter Summa canisters over a
10-minute period using laboratory supplied flow regulator calibrated with an approximate flow
rate of 100 mL/min. The vacuum of the Summa canisters will be measured at the start and end of
the sampling event, and will be recorded by sampling personnel and included on the sample chain-
of-custody record. The vacuum in each canister at the conclusion of the sampling event must
remain above 0 inches of mercury (inHg), and ideally at approximately -5 inHg, to allow for proper
laboratory analysis of the sample. The samples will be submitted to a qualified laboratory under
standard chain of custody protocols for analysis of volatile organic compounds (VOCs) by EPA
Method TO-15. If additional mercury sub-slab soil gas samples are collected, analysis for
elemental mercury by NIOSH Method 6009 will be conducted. The analytical laboratory will be
instructed to report J-flag concentrations for each sample. In addition, H&H will request that the
laboratory report compounds concentrations to the lower of the laboratory method detection limits
or the DEQ DWM Non-Residential Vapor Intrusion Sub-slab and Exterior Soil Gas Screening
Levels (SGSLs).

After receipt of the sub-slab soil gas sample analytical results, H&H will use the most recent
version of the DEQ Risk Calculator to evaluate cumulative vapor intrusion risks for a non-
residential worker scenario. In the case where calculated cumulative risks are less than 1x10-4 for
potential carcinogenic risks and below a hazard index of 1.0 for potential non-carcinogenic risks,
the VIMS will be considered effective.

Sub-slab soil gas sampling will be completed post-construction on an annual basis. Following two
annual sub-slab soil gas sampling events (including the initial post-installation sampling event)
with results within acceptable risk levels, a request to terminate efficacy monitoring will be
submitted for DEQ approval. Additional sub-slab soil gas sampling will be completed using the
methods discussed above.

In the event that calculated cumulative risks for a non-residential scenario continue to exceed
1x10-4 for potential carcinogenic risks and/or above a hazard index of 1 for potential non-
carcinogenic risks, indoor air sampling will be conducted as described below.

Indoor Air Sampling (if warranted)
Indoor air sampling (if warranted) will be conducted following construction of the building and
completion of the VIMS. If indoor air sampling is required, the number and locations of the indoor
air samples will be determined based on discussion between H&H and DEQ.

Indoor air samples will be collected in accordance with the DWM VI Guidance using a laboratory
supplied 6-liter individually certified Summa canister over an 8-hour period and analyzed for select
VOCs by EPA Method TO-15. The select analyte list will be determined based on the compounds
detected in the previously collected corresponding sub-slab soil gas sample.

Each indoor air Summa canister will be connected to a dedicated approximate 3 ft laboratory
supplied sampling cane which will place the sample intake point approximately 5 ft above grade
(typical breathing zone) with the canister set on its base. Periodic checks will be conducted by
H&H to monitor the pressure within the Summa canisters to ensure adequate sample volume is
collected. Following sample collection, the samples will be shipped to a qualified laboratory under
standard chain of custody protocol. The analytical laboratory will be instructed to report J-flag
concentrations for each sample. In addition, H&H will request that the laboratory report
compound concentrations to the lower of the laboratory method detection limits or the DEQ DWM
Non-Residential Vapor Intrusion Indoor Air Screening Levels (IASLs). For QA/QC purposes,
one duplicate indoor air sample and one background air sample will be collected during each
indoor air sampling event. In addition, an Indoor Air Building Survey form (Appendix C of the
DWM VI Guidance) will be completed for each sampling event.

Note that new construction materials such as paint, caulk, carpet, mastics, etc., which could be
sources of VOCs in indoor air, may cause interference with Site-specific compounds during indoor
air sampling. As noted above, the construction contractors will be requested to provide SDSs for
materials used during construction which will be submitted to DEQ.

Note that indoor air samples may be required, depending on the baseline mercury sub-slab soil gas
and potential follow-up sampling. In the event indoor air mercury samples are required, a separate
work plan will be submitted to DEQ via e-mail for approval prior to sample collection.

A report of the sub-slab soil gas and indoor air sampling (if warranted) will be submitted to DEQ
with the final VIMS Installation Completion Report. Based upon the results of the sampling, H&H
will make recommendations in general accordance with 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). Active fans will be installed as part of the VIMS and follow-up sampling will be
performed after installation of the fans should results of confirmation indoor air samples
indicate that passive treatment is inadequate (in the case where calculated cumulative risks
continue to be greater than 1x10-4 for potential carcinogenic risks or above a hazard index
of 1 for potential non-carcinogenic risks).

If additional indoor air sampling is required, modifications to the existing system will first be
evaluated to increase effectiveness (i.e., increasing the size of passive wind-driven turbine fans).
Should results of post-construction indoor air testing continue to indicate potential unacceptable
vapor intrusion risks to occupants of the building, active fans will be installed at the discharge end
of the riser duct piping (as needed) to convert the system from passive to active sub-slab
depressurization. DEQ will be notified of alterations to the system.

6.0 VIMS Effectiveness Monitoring

The VIMS is proposed as a passive system which will include vapor extraction through sub-slab
collection piping and wind-driven turbine ventilator fans. As such, differential pressure
monitoring is not anticipated. If the VIMS is converted to an active system based on
post-construction VIMS efficacy testing results, mitigation system modifications and plans for
additional VIMS efficacy testing will be submitted to the DEQ Brownfields Program for approval
prior to implementation. Actual fans to be used will be selected based on the results of the
influence testing discussed in Section 5.0.

Annual sub-slab soil gas monitoring will be conducted following completion of building
construction using sampling procedures described in Section 5.0. Following two annual sub-slab
soil gas monitoring events (with the post VIMS installation testing representing the first annual
sampling event) indicating results within acceptable risk levels, a request to terminate sampling
will be submitted for DEQ review and approval.

7.0 Future Tenants & Building Uses

The property owner or designee shall be responsible for installation and operation of the VIMS in
accordance with the VIMP. Future tenants for the proposed redevelopment have not yet been
determined. As such, portions of the concrete slab in each building will not be completed and will
be poured when future tenant utility installations have been completed. The VIMS is considered
functional without a completed floor slab, pending acceptable sub-slab soil gas sampling, indoor
air sampling (if warranted), and influence testing results as outlined in this VIMP. Controls such
as wooden boards and/or decking will be used to protect the vapor barrier from being punctured
following installation of the VIMS. Exposed vapor barrier in pour-back areas shall be labeled with
“Vapor System – Contact Owner”, or similar language. Additionally, tracer wire will be placed
on sub-slab horizontal collection piping to facilitate detection during future tenant upfits. Note
that the Site buildings will contain security controls that prevent other tenants from accessing
unfinished areas (exposed barrier) of the VIMS.

Future tenant upfit and sub-slab utility installations will require removal or penetration of the vapor
barrier. Following removal of the vapor barrier and completion of upfit and sub-slab utility
installation activities, a qualified contractor will repair and restore the vapor barrier or disturbance
of any other component of the VIMS in accordance with the VIMP. Restoration and repair to the
vapor barrier shall be performed per the manufacturer specifications provided in Attachment D
and summarized in Section 3.1 above. In addition, restoration and repairs to VIMS components
will be completed utilizing products and materials outlined in this VIMP unless other similar
product is pre-approved by a NC licensed Engineer.

Following VIMS restoration and repair activities and prior to placement of the concrete slab in a
tenant pour-back space, VIMS components will be visually inspected by a NC licensed Engineer
or designee, as outlined in Section 3.0 above. Note that each system component must be visible
to inspect and multiple inspections may be required (i.e., gravel layer and piping, if present, must
be inspected prior to repairing the vapor barrier). The concrete slab will not be poured in a tenant
space until VIMS components have been repaired and restored to the satisfaction of a NC licensed

Engineer. Documentation of system repairs and inspections will be provided to DEQ as an
addendum to the VIMS Installation Report at the completion of tenant upfit activities.

The property owner or designee will maintain the vapor mitigation piping and turbine fans in
accordance with the recorded Brownfields Agreement for the Site. If vapor mitigation components
are damaged or need to be altered for building renovations, the property owner or designee shall
contact a NC licensed Engineer to provided oversight and inspections, and a report will be
submitted to DEQ detailing the repairs or alterations. To aid in identification of the vapor
mitigation piping, the mitigation piping will be labeled with “Vapor System – Contact Owner”, or
similar language, on accessible piping at intervals of no greater than 10-linear feet.

DEQ will be notified within 60 days if the mitigation system is damaged, or ceases to operate as
designed. The notification will include a proposed course of action and estimated repair
timeframe. Once repairs have been implemented, the Brownfields Program will be notified with
results of these repairs.

8.0 Reporting

A VIMS Installation Completion Report (sealed by a NC-licensed PE) that documents installation
activities associated with the VIMS will be submitted to DEQ following confirmation that the
mitigation system is installed and effectively mitigating potential vapor intrusion risks for the
building. The report will include a summary of VIMS installation activities including photographs
and as-built construction drawings, QA/QC measures, SDSs of materials used in VIMS
construction, system effectiveness testing including sub-slab soil gas and indoor air (if needed)
assessment results, inspection documents, and an opinion as to whether the VIMS was installed in
accordance with the DEQ approved VIMP.

Additional sub-slab soil gas sampling of monitoring points will be completed on an annual basis
for a minimum of one event after the initial round of sampling, as described in Section 5.0. Within
60 days of the receipt of analytical data from this sampling, a soil gas sampling letter report
including risk calculators, and recommendations will be submitted to DEQ for review.

PRODUCT PART #
VaporBlock® Plus™ 20 ................................................................ VBP20
UNDER-SLAB VAPOR / GAS BARRIER
Under-Slab Vapor/Gas Retarder
© 2018 RAVEN INDUSTRIES INC. All rights reserved.
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
with factory welded seams are available based on minimum
volume requirements. Installation instructions and ASTM E-1745
classifications accompany each roll.

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 fourto eight slices about 3/8” less than the diameter of the pipe.
C) Force the square over the pipe leaving the tightly stretched cut areaaround the bottom of the pipe with approximately a 1/2” of theboot material running vertically up the pipe. (no more than a 1/2” ofstretched boot material is recommended)
D) Once boot is positioned, seal the perimeter to the membrane byapplying 2-sided Raven Butyl Seal Tape in between the two layers.Secure boot down firmly over the membrane taking care not tohave 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 halfof the release liner and wrap around the pipe allowing 1” extra foroverlap sealing. Peel off the second half of the release liner andwork the tape outward gradually forming a complete seal.
VaporSeal™ Tape (option) - Tape completely around pipeoverlapping the VaporBlock® Plus™ square to create a tight sealagainst the pipe.
F) Complete the process by taping over the boot perimeter edge withVaporSeal™ Tape to create a monolithic membrane between thesurface of the slab and gas/moisture sources below and at the slabperimeter. (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 tominimize the amount of POUR-N-SEAL™ necessary to seal around allpenetrations.
B) Once barrier is in place, remove soil or other particles with a dry clothor a fine broom to allow for improved adhesion to the POUR-N-SEAL™ liquid.
C) Create a dam around the penetration area approximately 2” awayfrom the pipe or other vertical penetrations by removing the releaseliner from the back of a 1” weather stripping foam and adhere to thevapor 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 sealantcompletely around penetrations creating a complete seal (Fig. 12-13).
E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longerthan 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.
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.

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®.

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®.
