Charlotte, North Carolina
Brownfields Project No. 25099-21-060
Dear Mr. Drury,
The North Carolina Department of Environmental Quality Brownfields Redevelopment Section
(DEQ Brownfields) received and reviewed the Vapor Intrusion Mitigation Plan (VIMP), Revision
2, dated March 2, 2023, and DEQ Brownfields has found this VIMP to be in compliance with the
Vapor Intrusion Mitigation System Design Submittal Requirements dated July 2021.
Consistent with standard brownfields vapor intrusion provisions, which will be included in 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 system effectiveness,
sub -slab soil gas sampling and indoor air sampling 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.

Vapor Intrusion Mitigation Plan — Revision 2
Beaty's Bindery Brownfields Property
Charlotte, North Carolina
Brownfields Project No. 25099-21-060
H&H Job No. AHI-007
1.0 Introduction
On behalf of 300 East 36 Development Holdings LLC (Prospective Developer or PD), Hart &
Hickman, PC (H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for the Beaty's
Bindery North Carolina Department of Environmental Quality (DEQ) Brownfields Property
(Brownfields Project No. 25099-21-060), also herein referred to as the Site. The Site is located
southeast of the intersection of Cullman Avenue and East 36th Street at the address 300 E. 36th
Street in Charlotte, Mecklenburg County, North Carolina. A Site location map is provided as
Figure 1.
The Site is located in the northern portion of an approximate 3.533-acre parcel of land (Parcel
#08303104) that was previously comprised of three contiguous parcels of land (Parcel #s
08303106, 08303105, and 08303104). The Brownfields will consist of approximately 2.25-acres
located in the northern portion of the of the 3.533-acre parcel. The rest of the parcels is currently
developed with the Charlotte Area Transit System (CATS) light rail line and will not be included
in the pending Brownfields Agreement.
The Brownfields portion of the Site was previously developed with the following structures:
• 3210 Cullman Avenue (western portion of the Site) - formerly developed with an ink
manufacturing facility, which operated until 1983.
• 3214 Cullman Avenue (central portion of the Site) — formerly developed with a vacant
10,000-square ft (sf) industrial office/warehouse building, which was constructed in 1964
and previously occupied several businesses, the most recent of which was Beaty's
Bindery (a printing and bindery company) from 1994 to 2014.

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

• 300 E. 36th Street (eastern portion of the Site) — formerly developed with a vacant
30,940-sf industrial office/warehouse building, which was constructed in 1953 and
occupied by a tire company until the end of 2021.
The Site is currently owned by the PD. The Site is bordered to the east by E. 36th Street, to the
north by Cullman Avenue, to the west by an undeveloped parcel, and to the south by rail lines.
A Site map is provided as Figure 2.
The PD is planning to redevelop the Site with a 7-story (8-levels total including a lower grade
"split-level" parking area) multi -family residential apartment building with associated amenity,
office, and commercial areas. The proposed building will be approximately 247, 101 -square ft in
size and will be comprised of 294 residential units, 357 parking spaces, a pool/clubhouse (Level
4), and courtyard areas (Level 4).
General descriptions of the 8 levels of the proposed building are as follows:
• Level 1 (ground level)— the lower portion of a "split-level" garage that covers 1/2 of the
building footprint in the western portion of the building and comprised of parking spaces,
an elevator, two stairwells, and a storage building;
• Level 2 (ground level)— the middle portion of the garage with residential units located
along the northwestern and northern portions of the building, and commercial units
located along the eastern portion of the building. Level 2 is also comprised of parking
spaces, two additional stairwells (4 stairwells total), trash and mechanical rooms, and
driveway access from the parking garage onto Cullman Avenue.
• Level 3 — the upper portion of the garage with residential units located along the
northwestern and northern portions of the building, a fitness center located in the
northeastern portion of the building, and commercial units located along the eastern
portion of the building. Level 3 is also comprised of storage units for the tenants and a
maintenance room.

• Level 4 (podium) — is comprised of residential units, a pool/clubhouse, courtyard areas on
podiums, mechanical and utility rooms.
• Levels 5, 6, 7, and 8 - are comprised of residential units and mechanical/utility rooms.
As noted above, the building will also include a multi -level ventilated parking garage void of
residences which will extend over large portions of the lower levels of the building, resulting in
limited ground level occupiable areas of the building with floor slabs constructed on grade (see
Figure 2). The majority of occupiable areas in the building will be constructed above the extents
of the parking garage.
1.1 Environment Conditions
During 2019 through 2021, Phase I Environmental Site Assessment (ESA) activities were
completed on the Site parcels and Recognized Environmental Conditions (RECs) associated with
the parcels were identified. A brief summary of the Phase I ESA findings for the Site parcels is
provided below.
1.1.1 Phase I ESA Summary
3210 Cullman Avenue
The former Inx International Ink Company (Inx) facility operated on the 3210 Cullman Avenue
parcel and on the adjacent parcel to the west (3200 Cullman Avenue) from an unknown date
until 1983. Use of chromium and lead in ink production processes, and soil and groundwater
impacts identified on the parcel during previous assessment activities conducted in 2005 and
2020 were identified as RECs. During 2005, total chromium and total lead were detected at
maximum concentrations of 250 milligrams per kilogram (mg/kg) and 920 mg/kg, respectively
in soil samples collected from the parcel. Low concentrations of tetrachloroethylene (PCE) and
the pesticide dieldrin were also detected in soil samples collected during the 2005 assessment
activities. During the 2005 assessment activities, n-propylbenzene, 1,2,4-trimethylbenzene, and
1,3,5-trimethylbenzene were detected above 15A NCAC 02L .0202 ground water standards
(2L standards) in a monitoring well installed on the south side of the former Inx building. These

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

compounds are typically associated with petroleum -related sources and may be associated with
the use of petroleum -based inks at the facility.
The Trex Properties (Trex) is located at 3114 and 3124 Cullman Avenue approximately 400 ft
west and topographically cross -gradient of the subject Site. Waste solvent recycling was
formerly conducted at the Trex facility beginning in 1983. During groundwater assessment
activities conducted in the area of the Trex site between 2008 through 2019, multiple chlorinated
volatile organic compounds (VOCs) were detected at relatively high concentrations above
2L standards. For example, PCE was detected at concentrations as high as 50,500 micrograms
per liter (µg/1) and trichloroethylene (TCE) was detected at concentrations as high as
128,000 µg/l. The 2L standards established for PCE and TCE are 0.7 µg/l and 3 µg/l,
respectively. Four Trex monitoring wells (identified as PMW-16A, PMW-16B, PMW-17A, and
PMW-17B in Attachment Al) are located on the 3200 Cullman Avenue property (adjacent to the
west of the Site). During February 2019, relatively high concentrations of chlorinated VOCs
were detected in these four wells, including a maximum PCE concentration of 903 µg/l and a
maximum TCE concentration of 4,120 µg/l. Based on the proximity of these monitoring wells to
the Site, it is likely that elevated chlorinated VOC concentrations associated with the Trex
release extend beneath the 3210 Cullman Avenue parcel (i.e., beneath the western portion of the
Site).
3214 Cullman Avenue
The 3214 Cullman Avenue building was initially constructed in 1964 and consists of offices,
restrooms, an employee break room, and warehouse space. The facility was historically
occupied by a beer distributor (1969), transmission supplier (1969-1974), picture frame
distributor (1974-1989), chimney sweep (1979), and Beaty's Bindery printing and bindery
company (1994-2014). H&H could not obtain specific reports or information documenting
chemical storage or disposal practices of the former Site tenants, and details regarding the
historical use and storage of chemicals on Site are unknown. Based on review of a Limited Site
Investigation Report prepared by Terracon dated March 30, 2015, for the NoDa TextilesNewco
Fibre Property (430 E. 36th Street), PCE was detected above the 2L standard in a groundwater
sample collected approximately 150 ft southwest cross -gradient to upgradient of the Site.

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

Therefore, impacts possibly associated with the NoDa Textiles property (in addition to impacts
associated with 3210 Cullman Ave parcel (discussed above) were identified as RECs associated
with the 3214 Cullman Avenue parcel.
300 E. 36th Street
The former L&N Tire facility located at 300 E. 36th Street is listed on the Leaking Underground
Storage Tank (LUST) database (Incident # 16670). Soil impacts were identified in 1990 during
the removal of a 1,000-gallon diesel underground storage tank (UST). According to historical
reports, approximately 200 cubic yards (cy) of petroleum -impacted soil were excavated after
removal of the UST, and results of analysis of two post -excavation soil samples indicated that
petroleum -impacted soil had successfully been removed. On August 16, 1990, DEQ issued a no
further action (NFA) letter for the release incident and requested a remedial plan for the
excavated soil. The approximately 200 cy of impacted soil removed from below the UST were
stockpiled on the property and tilled to reduce volatile contaminant concentrations. L&N Tire
subsequently requested approval for reuse of the soil as rail spur cover material. In 1991, DEQ
issued a Certificate of Approval for Disposal of Petroleum Contaminated Soils allowing the soil
to be spread over a rail spur on the property. A 2019 Phase I ESA report prepared by Bunnell
Lammons Engineering (BLE) identified the potential for petroleum impacted soil to remain
along the rail spur as a REC, oil stains from air compressors located on a loading dock on the
southside of building and ground surface as a REC, and removed former UST as a historical
REC (HREC), which H&H identified below to be a REC.
H&H identified oil staining to the concrete pad below two air compressor units staged behind the
300 E. 36th Street building in the southeastern portion Site. The compressor oil has migrated off
of the pad to impact the ground surface adjacent to the pad. H&H conducted Phase II ESA
sampling activities in December 2020 to further assess the oil stain associated with the air
compressors. Soil sample SB-7 collected within the oil stain did not detect VOCs or SVOCs at
concentrations above DEQ PSRGs. Based on the results of soil sampling activities, it does not
appear that the compressor oil stain has impacted soil in this area above DEQ screening levels.
However, during a December 2020 Phase II ESA sampling event, naphthalene (87 µg/L) was
detected in a groundwater sample collected from a temporary monitoring well (TMW-5)

installed in the southeastern portion of the Site at a concentration above the DEQ 2L Standard of
6 µg/L and above the DEQ Residential and Non -Residential GWSLs of 4.6 and 20 µg/L,
respectively. Based on this information, H&H considers naphthalene detections in groundwater
in the southeastern portion of the subject Site to be a REC.
1.1.2 Phase 11 ESA Summary
During December 2020, H&H conducted Phase II ESA soil, groundwater, soil gas, and sub -slab
vapor sampling activities to assess current environmental conditions at the Site, and the methods
and results of these activities are summarized in the Phase H Environmental Site Assessment
Cullman Avenue Assemblage report dated December 30, 2020. In order to address potential
post -redevelopment environmental concerns, the PD submitted a Brownfields Property
Application for the Site to DEQ during December 2021, and the DEQ Brownfields Program
subsequently issued a letter of eligibility (LOE) dated March 31, 2022, for the Site. A Notice of
Brownfields Property (Brownfields Agreement) is currently being drafted by DEQ. During
August 2022, H&H conducted additional soil, soil gas, and sub -slab vapor sampling activities at
the Site to further assess environmental conditions and to address potential data gaps in support
of the Site's application to the Brownfields Program. The methods and results of the
August 2022 Phase II ESA activities are summarized in the Brownfields Assessment Report
dated November 3, 2022, submitted to DEQ. A map which depicts the August 2022 sample
locations and sample data summary tables are included in Attachment A. A brief summary of
the sampling results is provided below. Please refer to the reports referenced above for
additional information.
Soil Sample SummarX
As shown in Table Al, there were no VOCs or pesticides detected above DEQ Residential or
Industrial/Commercial Preliminary Soil Remediation Goals (PSRGs) in soil samples collected
from the Site. The semi-VOCs (SVOCs) benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, dibenzo(a,h)anthracene, and indeno(1,2,3-cd)pyrene were detected above
Residential PSRGs in one sample (SB-17), and the benzo(a)pyrene detection in the sample is
also above the Industrial/Commercial PSRG. Benzo(a)pyrene was also detected at estimated

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

concentrations slightly above the Residential PSRG in two additional samples (SB-5 and SB-14).
As shown in Attachment Al, SB-17 was collected in the central portion of the Site within the
proposed building footprint, SB-5 was collected in the southern portion of the Site within the
proposed building footprint, and SB-14 was collected in the eastern portion of the Site outside of
the proposed building footprint. There were no other SVOCs detected above Residential or
Industrial/Commercial PSRGs in the soil samples. Arsenic was detected above background and
Residential and Industrial/Commercial PSRGs in three samples (SB-5, SB-8, and SB-12) which
are located within the proposed building footprint, and hexavalent chromium was detected in
11 samples at relatively low concentrations above the Residential PSRG, but below the
Industrial/Commercial PSRG. There were no other metals detected in Site soil samples above
background and Residential or Industrial/Commercial PSRGs.
Groundwater Sample Summary
Five temporary monitoring wells were installed on the Site and sampled during December 2020.
As shown in Table A2, results of analysis of the samples indicate naphthalene (as a VOC and
SVOC) was detected above the 2L standard in one well (TMW-5 located in the southeast corner
of the Site) and PCE was detected at relatively low concentrations above the 2L standard in two
wells (TWM-1 and TMW-2 located in western portions of the Site). There were no other VOCs
or SVOCs detected above 2L standards in the temporary wells, and there were no metals
detected above 2L standards in the wells. The naphthalene detections (i.e., as a VOC and
SVOC) in TMW-5 are also higher than the Residential Vapor Intrusion Groundwater Screening
Level (GWSL), and the naphthalene detection as a VOC is higher than the Non -Residential
GWSL. In addition, chloroform (a potential laboratory artifact) and TCE were detected above
Residential GWSLs, but below Non -Residential GWSLs in TMW-1 (TCE) and TWM-2
(chloroform). There were no other VOCs or SVOCs detected above GWSLs in the temporary
wells.
Soil Gas Sample Summary
Soil gas samples have been collected from eight locations at the Site, each of which is located
within the proposed building footprint. Three of the sample locations (SGV-1 through SGV-3)
are outside of existing building structures (i.e., exterior soil gas samples), and the remaining

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

locations are inside of existing building structures (i.e., sub -slab sample locations). Soil gas
samples were collected from five of the sample locations (SSV-1 through SSV-5) on two
occasions, and one sample has been collected from the remaining locations. As shown in
Table A3, results of analysis of the soil gas samples indicate benzene was detected slightly above
the Residential Vapor Intrusion Sub Slab and Exterior Soil Gas Screening Level (SGSL) in
SGV-1, ethylbenzene was detected slightly above the Residential SGSL in SGV-2, and
chloroform (a potential laboratory artifact) was detected above the Residential SGSL in SGV-1
through SGV-3. The chloroform detection in SGV-1 was also slightly higher than the Non -
Residential SGSL. These three exterior soil gas sample locations are generally located in
western portions of the Site. Naphthalene was detected slightly above the Residential SGSL and
below the Non -Residential SGSL during August 2022 in each of the sub -slab sample locations
samples. There were no other compounds detected above SGSLs in the soil gas samples,
including PCE and TCE.
1.2 Vapor Intrusion Risk Evaluation
H&H utilized the DEQ Risk Calculator (July 2022 version) to evaluate potential cumulative risks
for the soil gas to indoor air vapor intrusion pathway using the highest concentration of each
compound detected in soil gas samples collected from the Site in order to evaluate potential risk
posed by vapor intrusion under a hypothetical "worst -case" scenario. Risk Calculator runs for
the soil gas to indoor air exposure pathway were run for both residential and non-residential use
scenarios. Copies of the Risk Calculator input and output forms are provided in Attachment A
and a summary of the calculated cumulative lifetime incremental carcinogenic risk (LICR) and
hazard index (HI) for each scenario is presented below.

Case Value
Calculated Carcinogenic Risk
1.9 x 10-6
Calculated Non -Carcinogenic Hazard Index
0.028
Calculated LICR or HI Exceeds Acceptable Non -Resident Risk Levels?
No
Typically, vapor intrusion mitigation for a building is not considered warranted if the cumulative
LICR is 1 x 10-4 or less and the cumulative HI is 1.0 or less. As indicated above, the calculated
LICRs are within the acceptable risk range of 1 x 10-4 to 1 x 10-6 and the calculated HIs are less
than 1 for both the residential and non-residential use scenarios. Although calculated risks from
potential vapor intrusion under a "worst case" scenario at the Site are acceptable, due to the
detection of chlorinated VOCs (CVOCs) including TCE at the Site, the PD plans to implement
vapor mitigation measures to reduce the potential for vapor intrusion into the proposed building
as a conservative, protective measure.
Based on a review of laboratory analytical data for environmental media samples collected at the
Site and the vapor intrusion risk evaluation results discussed above, potential structural vapor
intrusion can be managed by passive vapor intrusion mitigation measures installed during
construction of the proposed Site building. As previously mentioned, the proposed building will
include a multi -level ventilated parking garage which will extend over large portions of the lower
levels of the building, resulting in limited ground level occupiable areas of the building with
floor slabs constructed on grade which are subject to potential vapor intrusion from the
subsurface (see Figure 2). Vapor intrusion mitigation measures will be implemented to address
these occupiable areas. In addition, vapor intrusion mitigation measures will be implemented at
stair well and elevator locations to address vapor intrusion into these features since they have the
potential to be vapor conduits to occupiable areas.
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." This VIMP was
prepared to satisfy the standard vapor intrusion mitigation provisions anticipated to be included
in the pending Brownfields Agreement. Per the North Carolina Brownfields Property Reuse Act
130A-310.32, a PD, with the assistance of H&H for this project, is to provide DEQ 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 (VIMS) detailed herein is designed to mitigate intrusion
of subsurface vapors into the subject building 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
A passive VIMS will be installed during construction of the proposed Site building to reduce the
potential for intrusion of soil vapor into the building. The VIMS plan, detail, and specification
sheets (VM-IA, VM-1B, VM-2, VM-3, and VM-4) included in Attachment B will be used to
guide installation of the VIMS. The VIMS will include vapor barrier components installed
beneath stair wells, elevator shafts, and occupiable ground level areas of the building, and sub -
slab venting components consisting of horizontal sub -slab and vertical above -slab riser piping
connected to turbine ventilators installed on the building roof.
The proposed building includes two ground -floor levels (identified as Level 1 and Level 2 in the
VIMS design plans) with all or portions of the levels constructed with slabs on grade. Level 1
will be located in the western portion of the building and extend across approximately one-half
of the proposed building's footprint. A vertical retaining wall will be constructed along the
eastern portion of the Level 1 area. Level 2 will extend across the entire footprint of the
proposed building, including above Level 1. As previously mentioned, parking garages will
extend over large portions of the lower levels of the building (see VM-1 A and VM-1 B). The
garages will be open along the south side of the building, and perforated metal screen exterior
paneling will be installed along garage areas which extend to the western and northern sides of
the building. In addition, the garages areas will be ventilated with exhaust fans.
The VIMS will address an approximately 700 square foot (sf) area (which includes stair well and
elevator areas only) of Level 1, and an approximately 2,600 sf area (which includes residential
units and a stair well) and an approximately 14,000 sf area (which includes office, commercial,
utility room, amenity, stair well, and elevator areas) of Level 2. The extents of the VIMS are
identified by the vapor barrier extent/perimeter lines shown in VM-lA and VM-IB. Vertical
walls connected to occupiable spaces will be in contact with Site soil in some areas of the Site
building with vapor barrier installed along applicable walls (Section 2.1) as indicated in the
designdrawings.; however-, potential for- fnngr-atier through vet4ieal walls an

Note that an approximately 5,300 sf "pour -back" area is included in the eastern portion of the
proposed building in the area identified in VM-1B. This space is intended for future commercial
use by one or more tenants, and concrete floor slabs will not be poured in this space until tenants
are identified and upfit plans are finalized. However, VIMS components will be installed in this
space during building construction. Additional details regarding the measures to be implemented
for the pour -back area are provided in this VIMP.
VIMS components and installation are discussed in the sections below. Refer to the VIMS plan,
detail, and specification sheets included in Attachment B for additional VIMS details and VIMS
component locations. VIMS components shall be inspected by the engineer certifying this VIMP
(hereafter the Engineer), or by the Engineer's designee to ensure that the VIMS is installed in
accordance with this VIMP. VIMS inspections are discussed in Section 3.0. Deviations from
the VIMS design must be approved by the Engineer, and notification of deviations will be
provided to DEQ.
2.1 Base Course Layer and Vapor Barrier
The VIMS includes placement a of 5-inch thick (minimum) base course layer consisting of high
permeability clean #57 stone below concrete slabs located within the extents of the VIMS vapor
barriers. The extents of the VIMS vapor barriers are depicted in VM-lA and VM-113
(Attachment B). The vapor barriers will be installed above the base course, and concrete slabs
(including thickened slabs and depressed footings) will be poured directly over the vapor
barriers. The vapor barriers will also be installed around elevator pits and will be sealed to
columns and sub -grade retaining walls with deeper footers. Venting pipe networks (discussed in
Section 2.2) will be installed within the base course prior to installation of vapor barriers.
The vapor barriers will consist of VaporblocV Plus 20 (VBP-20) manufactured by Raven
Industries (Raven), or Drago® Wrap Vapor Intrusion Barrier (Drago Wrap) manufactured by
Stego® Industries (Stego). These products are volatile organic compound (VOC)-rated. The
vapor barriers will be installed per manufacturer installation instructions to create continuous
barriers within each VIMS area. The manufacturer instructions include methods for vapor

barrier overlapping and joint sealing, for sealing vapor barriers to footings, columns,
penetrations, etc., and for repairing tears/punctures in the barriers. Raven and Stego recommend
select sealing products (mastics, tapes, etc.) for use in vapor barrier installation. In accordance
with manufacturer installation instructions, alternative sealing products that are not
manufacturer -approved should not be used unless approved by the Engineer and manufacturer.
Following successful installation of the vapor barrier, concrete will be poured directly on top of
the continuous vapor barrier, further enhancing barrier integrity at seams and penetrations. For
the pour -back area, the vapor barrier will be installed and sealed across the area following
installation of sub -slab venting pipe in the area. The vapor barrier in the pour -back area will not
be covered with concrete until a tenant is identified for the space. VBP-20 and Drago Wrap
technical specifications are included as Attachments C-1 and C-2, respectively.
2.2 Venting Pipe Network
Passive sub -slab venting will be accomplished using pipe networks which include horizontal
slotted or perforated pipe installed in the base course beneath the floor slabs and solid riser pipe
extending from the slotted pipe to above the building roofline, and a wind -driven Empire Model
EV04SS turbine ventilator (or Engineer -approved alternate) installed at the top of the riser pipe.
Venting pipe layouts are depicted in VM-1A and VM-1B (Attachment B). Vapor will discharge
from the ventilator to the atmosphere a minimum of two ft above the building roofline and a
minimum of 10 ft from an operable opening (e.g., door or window) or air intake. The sub -slab
and above -slab venting pipe will consist of 3-inch diameter Schedule 40 (SCH 40) PVC pipe and
fittings, unless otherwise specified. Solid sections of venting pipe will be installed with a
minimum 1% slope toward slotted pipe sections in order to drain condensate. A slotted PVC
pipe specification sheet for a product which may be used as horizontal sub -slab venting pipe is
provided as Attachment C-3. Note that electrical junction boxes (120VAC) will be installed on
the roof top in proximity to ventilators so that electrical (active) fans can be connected to the
venting/depressurization piping in the future (if determined to be needed).
As an alternative to the 3-inch diameter SCH 40 PVC horizontal slotted/perforated venting pipe,
soil gas collector mat manufactured by Radon Professional Discount Supply (Radon PDS) may

avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

be used for sub -slab vent 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 sub -slab soil gas. If used, the soil gas collector
mat will be connected to 3-inch diameter solid pipe at transitions to vertical riser and through
footings using Radon PDS-manufactured riser connection fittings. Radon PDS soil gas collector
mat product information is provided as Attachment C-4.
2.3 Sub -Slab Monitoring Points
Sub -slab monitoring points will be installed in the locations identified in VM-1 A and VM-1 B
(Attachment B) to allow for depressurization effectiveness testing (see Section 4.1) and sub -slab
soil gas sample collection (see Section 4.2). Each monitoring point will be constructed with 2-
inch diameter SCH 40 PVC extending through the floor slab into the base course. The top of
each monitoring point will be set within a Zurn Industries Model #CO2450-PV4 floor cleanout
(or, Engineer -approved alternate) installed flush with the top of the slab. The monitoring points
are generally located in areas which will be finished with concrete slab floors and are positioned
to provide data which will be adequate for evaluating depressurization effectiveness (during
testing). Please note that monitoring point IMP-2 has been proposed within the Stair B stairwell
at DEQ's request. This location is above a mat footer and surrounded by shear walls that will be
wrapped with vapor barrier, and vacuum influence is therefore not expected in the sub -slab
annular space below the Stair B stairwell. The sub -slab annular space of this stairwell is not
proposed to connect to sub -surface soils, and passive venting below this stairwell is therefore not
warranted.
In the event that a monitoring point cannot be installed due to building component conflict or is
damaged/destroyed during construction, a replacement point will be constructed as approved by
the Engineer. DEQ will be notified in advance if a monitoring point is relocated greater than
10 ft from the location specified in the DEQ-approved VIMP. Final monitoring point types and
locations will be documented in as -built drawings provided in a VIMS installation completion
report (discussed in Section 7.0).

2.4 General Installation Criteria
Prior to completion of the slab pour in the commercial pour -back area, the area will be secured,
and access restricted to persons other than the PD and its employees and contractors. In the case
that construction/maintenance activities are conducted in the area prior to the slab pour, controls
such as wooden boards and/or decking will be placed over the vapor barrier in the active areas to
prevent damage to the barrier. Temporary wooden boards and/or decking will also be installed
during tenant upfit activities to minimize damage to the vapor barrier from construction workers.
In addition, signage indicating precautions should be taken to prevent vapor barrier damage will
be posted in prominent locations around the pour -back area. Future tenant upfit of the
commercial space will likely include installation of sub -slab utilities within/through the base
course and vapor barrier. As such, portions of the vapor barrier may be removed during the
process for short periods of time. The upfit construction contractor will be instructed to ventilate
the upfit space to outdoor air if and when portions of the vapor barrier are removed. It is not
expected that trenching or other major disturbance to underlying soil will be required in the area,
or that VIMS piping will be affected by the activities. The vapor barrier will be sealed to new
penetrations (if any) associated with the upfit activities in accordance with the vapor barrier
manufacture instructions. Notification requirements for activities which affect or have the
potential to affect VIMS components in the pour -back area and inspection requirements for
VIMS components in the pour -back area are discussed in Section 3.0. Installation of concrete
floor slabs in the pour -back area shall not be completed prior to inspection and approval by the
Engineer (or, Engineer's designee).
For VIMS component construction (above and below slab), installation contractors and sub-
contractors shall use "low or no VOC" products and materials. Furthermore, the installation
contractors shall not use products containing the compounds PCE or TCE. Prior to submittal of
a VIMS installation completion report (see Section 6.0), the installation contractor and sub-
contractors shall be directed to provide safety data sheets (SDSs) for products and materials used
for VIMS construction. SDSs provided by the contractor and subcontractors will be included in
the VIMS installation completion report.

Previous assessment and evaluation activities do not indicate unmitigated vapor intrusion into the
proposed Site building would pose unacceptable risk to future building occupants and thus no
known area of elevated VOC impacts which pose unacceptable risks are present on the Site.
Utility trenches within the building footprint are proposed to be backfilled with compacted soils
thereby minimizing the potential for these features to act as soil gas conduits. In addition, utility
trench dams will be installed along utility trenches which extend beneath the Site building
footprint from areas outside the building footprint to further reduce the potential for lateral vapor
migration along the utility lines.

3.0 Quality Assurance / Quality Control
For quality assurance and quality control (QA/QC) purposes, VIMS components will be
inspected by the Engineer (or, Engineer's designee) to ensure that the VIMS is installed in
accordance with this VIMP, and product manufacturer instructions/recommendations as follows:
(1) Inspection of the base course layer, sub -slab venting pipe networks, and monitoring
points will be completed and approved prior to installation of vapor barriers;
(2) Inspection of the vapor barriers will be completed and approved prior to pouring concrete
and prior to placement of backfill against applicable sub -grade vertical walls;
(3) Inspection of above -grade vertical riser piping prior will be completed and approved prior
to enclosing in walls; and,
(4) Inspection of turbine ventilators and riser pipe connections will be completed and
approved after installation.
Additional inspections will be conducted if the system(s) are activated to verify electric fans (if
installed) function as designed. Inspections will be combined, when possible, depending on
construction sequencing and schedule. The inspections will include field logs and photographs
for each VIMS area. Locations where multiple penetrations are present and sealed will be
photographed and noted in the field logs. 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 construction contractor shall notify the Engineer (or, Engineer's designee) a
minimum of 48 hours prior to a requested inspection, and H&H will subsequently notify DEQ of
each scheduled inspection.
Please note that the DEQ-approved Environmental Management Plan (EMP) for the Site requires
written notice be provided to the Brownfields Project Manager 10 days in advance of the start of
construction/grading, Site assessment/remediation, and mitigation system installation activities.
The PD will provide these written notices to DEQ and will also notify DEQ and the Engineer (or,

WAPMR INVWOMMCH7AI SOLUTIONS

Engineer's designee) a minimum of 10 days in advance of the start of commercial upfit activities
in the pour -back area (see below).
Pour -Back Area
The PD (or its designee) will provide notice to the Engineer (or, Engineer's designee) prior to
performing activities in the pour -back area which may affect the vapor barrier or other VIMS
components. In addition, DEQ will be notified once tenants of the pour back areas are identified.
Any damages to the vapor barrier or other VIMS components during (or, prior to) retrofit
activities will be repaired at that time in accordance with the applicable instructions (i.e., the
vapor barrier manufacture instructions, VIMP, or Engineer instructions) and will be inspected by
the Engineer (or Engineer's designee). In addition, any penetrations of the vapor barrier during
(or, prior to) retrofit activities will be sealed at that time in accordance with the vapor barrier
manufacture instructions.
If notable changes to the VIMS piping are needed in the pour back area, the changes or
modifications will be reviewed by the Engineer and submitted to DEQ for approval prior to
implementation. An inspection of the vapor barrier and other affected VIMS components (if
any) will be completed by the Engineer (or Engineer's designee) prior to pouring the concrete
floor slab in the area, and the slab will not be poured until VIMS components in the area are
installed in accordance with the DEQ-approved VIMP and to the Engineer's satisfaction. The
upfit construction contractor shall notify the Engineer (or, Engineer's designee) a minimum of 48
hours prior to a requested inspection, and H&H will subsequently notify DEQ of each scheduled
inspection. If repairs and/or modifications to the VIMS in the pour -back area are made, a
summary will be reported to DEQ within 30 days of completion.

4.0 VIMS Effectiveness Testing and Monitoring
Despite the fact that calculated risks from potential vapor intrusion into the proposed Site
building under a "worst case" scenario are acceptable, the PD plans to install a VIMS in the
proposed Site building to reduce the potential for vapor intrusion as a conservative, protective
measure. In addition, sub -slab depressurization testing and pre- and post -occupancy sub -slab
soil gas and indoor air monitoring will be completed to further demonstrate VIMS
protectiveness. Note that the post -occupancy sub -slab soil gas monitoring and pre- and post -
occupancy indoor air monitoring proposed herein are required by DEQ as a condition of VIMP
approval. These activities are discussed below.
4.1 Depressurization Testing
Post -installation (pre -occupancy) sub -slab depressurization testing will be conducted on each
VIMS area to evaluate pressure differential between the sub -slab and above slab regions, and to
confirm sufficient sub -slab depressurization can be obtained should electric fans be incorporated
into the VIMS in the future. Depressurization testing will be conducted for each VIMS area
following installation of venting piping, vapor barrier, and concrete floor slabs. Because the
VIMS is a passive system with wind -driven turbine ventilators, sub -slab depressurization is
expected to vary with ambient wind conditions, and sub -slab depressurization will therefore not
be monitored after building construction and occupancy.
For VIMS depressurization 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 monitoring
point locations. A minimum pressure differential of 4 pascals (approximately 0.016 inches of
water column) at each monitoring point will be considered adequate for demonstrating that
sufficient sub -slab depressurization can be obtained should electric fans be incorporated into the
VIMS in the future. VIMS depressurization testing results will be provided in the VIMS
installation completion report. Monitoring point locations are depicted in VM-lA and VM-113
(Attachment B). Monitoring points IMP-1 through IMP-5 will be used for pre -occupancy sub -

slab depressurization testing only and may be abandoned following completion of a successful
depressurization test, with DEQ approval. Note that monitoring point IMP-2 has been proposed
within the Stair B stairwell at DEQ's request; however, vacuum influence is not expected in the
sub -slab annular space at this location. Refer to Section 2.3 for additional details.
4.2 Sub -Slab Soil Gas and Indoor Air Monitoring
Following VIMS installation and prior to occupancy of the building, sub -slab soil gas samples
will be collected from seven monitoring points (identified as MP-1 through MP-7 in VM-IA and
VM-1 B) to further evaluate the potential for structural vapor intrusion. Following building
occupancy, sub -slab soil gas samples will be collected from the same seven monitoring points on
a semi-annual basis for a minimum of two years (i.e., a minimum of four post -occupancy
sampling events). In addition, indoor air monitoring events will be completed at the approximate
time of each of these sub -slab soil gas monitoring events. During each event, an indoor air
sample will be collected from four locations (identified as IAS-1 through IAS-4 in VM-lA and
VM-113). Sub -slab soil gas and indoor air sampling methods are discussed in the sections below.
Modification to the number and/or locations of samples may be requested in reports submitted to
DEQ after each round of monitoring is completed.
As previously mentioned, and despite the fact that the VIMS is being installed as an extremely
conservative protective measure where calculated risks from potential vapor intrusion into the
proposed Site building under a "worst case" scenario are acceptable, the post -occupancy sub -slab
soil gas monitoring and the pre- and post -occupancy indoor air monitoring proposed herein are
required by DEQ as a condition of VIMP approval.
4.2.1 Sub -Slab Soil Gas Sampling
Prior to collection of sub -slab soil gas samples, a leak test will be performed at each monitoring
point location as follows. A shroud will be constructed around the monitoring point and sub -slab
soil gas sampling train and sample canister. The shroud will be flooded with helium gas, and
helium concentrations will be measured and maintained using a calibrated helium gas detector.
Id

an
documents/aaa-masterprojects/avery hall investments (ahi)/ahi-007 Cullman 3 APMR [NVWOMMCHTAI SOLUTIONS
avenue brownfields/vimp/beaty's bindery vimp rev 2.doc

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 (i.e., a
passing leak test). A minimum of three sample train volumes will be purged from each point
prior to and during the leak testing activities. If the leak test fails, troubleshooting will be
completed to identify the source of the leak (or, test deficiency), and the identified
source/deficiency will be addressed to the satisfaction of the Engineer.
The sub -slab soil gas samples will be collected over an approximate 10-minute period using
laboratory supplied and batch -certified 1-liter or 1.4-liter Summa canisters and laboratory
supplied flow regulators calibrated for an approximate flow rate of 100 milliliters per minute.
One duplicate sub -slab soil gas sample using a laboratory -supplied "T" fitting for laboratory
QA/QC purposes will be collected during the sampling event. 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 (in Hg), with a target vacuum of approximately 5 in Hg.
H&H understands that analytical results for a sample may not be accepted by DEQ if the internal
vacuum for that sample reaches 0 in Hg.
The sub -slab soil gas samples will be submitted to a laboratory under standard chain of custody
protocols for analysis of full -list VOCs by EPA Method TO-15, including the analyte
naphthalene. The analytical laboratory will be instructed to report vacuum measured in the
Summa canisters upon receipt and to report compound concentrations to the lower of the
laboratory method detection limits or the DEQ DWM Residential SGSLs (to the extent possible).
4.2.2 Indoor Air Sampling
Indoor air samples will be collected from the approximate locations shown in VM-IA and VM-
1B (four locations) prior to collection of the sub -slab soil gas samples (discussed above). 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 the samples to be collected over an
approximately 24-hour period for a residential use scenario. A laboratory supplied 3-foot
sampling cane will be connected to the flow controller so that the sample intake point is
positioned approximately five ft above grade (typical breathing zone height) when the sample
canister is set on its base. In addition, one duplicate sample will be collected and one
background sample from an ambient (outdoor) air location upwind of the building will be
collected.
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. 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, and
sample collection will be stopped when vacuum levels in the canisters are approximately 5 in
Hg. The starting and ending vacuum in each canister will be recorded on the sample chain of
custody. The sample canisters will then be labeled and shipped under standard chain of custody
protocols to a laboratory for analysis of select VOCs by EPA Method TO-15. The select VOC
list will initially include VOCs which have been detected in samples of environmental media
previously collected from the Site, and the analyte list may be adjusted for post -occupancy
sampling events base on the results of the pre- and post -occupancy sub -slab soil gas and indoor
air sampling results, and as presented in reports submitted to DEQ. The analytical laboratory
will be instructed to report vacuum measured in the Summa canisters upon receipt and to report
compound concentrations to laboratory method detection limits.
Note that 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. Sampling personnel will attempt to
identify potential sources of VOCs in indoor air which are associated with construction
materials, and an Indoor Air Building Survey form (Appendix C of the DWM VI Guidance) will
be completed for the indoor air sampling event.

4.3 Sub -Slab Soil Gas and Indoor Air Sample Results and Evaluation
After receipt of the sub -slab soil gas and indoor air sample analytical results for each monitoring
event, H&H will use the most recent version of the DEQ Risk Calculator to evaluate cumulative
risks. If the results of the evaluation indicate a calculated cumulative LICR of 1x104 or less and
a HI of 1.0 or less, no additional assessment or evaluation will be completed prior to next semi-
annual post -occupancy sampling event. In the case that the calculated cumulative LICR is
greater than 1x104 and/or the HI is greater than 1.0, additional sampling and/or risk evaluation
will be completed, or the VIMS may be converted to an active system (with electric fans). H&H
will discuss indoor air (if completed) evaluation results and potential VIMS modifications with
DEQ prior to making a determination regarding system modification. If the VIMS is converted
to an active system with electric fans based on the VIMS effectiveness testing, a VIMS
modification and monitoring plan will be submitted to the DEQ Brownfields Redevelopment
Section for approval.
Pre -occupancy sub -slab soil gas and indoor air sampling methods, results, and evaluations
discussed above will be documented in the final VIMS installation completion report submitted
to DEQ (see Section 6.0). Post -occupancy sub -slab soil gas and indoor air monitoring events
will be completed on a semi-annual basis as discussed above. After each semi-annual
monitoring event, a report will be submitted to DEQ to document the sampling methods, results,
and evaluations. If evaluation of the sub -slab soil gas and indoor air sample results indicates
acceptable risk levels after the fourth semi-annual monitoring event, a request to terminate the
monitoring will be submitted for DEQ approval. Changes to the post -construction VIMS
effectiveness monitoring will not be implemented until written approval is obtained from DEQ.

5.0 Future Tenants & Building Uses
Future anticipated use of the proposed Site building is for multi -family residential (with
associated amenity and office areas) and limited commercial. After occupancy of the building,
VIMS maintenance and upkeep will be the responsibility of the building owner or property
management group. The VIMS installation report will include as -built drawings and
specification sheets for components included in VIMS construction. If VIMS components are
damaged or need to be altered for building renovations, the building owners or management shall
contact a North Carolina licensed Professional Engineer (NC PE) and the DEQ Brownfields
Redevelopment Section for direction and oversight, and for inspection of any VIMS
modifications or repairs. Following completion of any VIMS alterations or repairs, a report will
be submitted to DEQ detailing the alterations or repairs.
To aid in future identification of above grade VIMS piping, accessible portions of the piping will
be labeled by means of a tag or stencil with "Vapor Mitigation — Contact Maintenance" (or
similar), and the labeling will be applied to every 10-linear ft of accessible pipe (at minimum).
The portion of each VIMS riser pipe above the roofline will be labeled in this manner.
As part of the standard annual Land Use Restriction Update submittal that will be required as
part of the pending Brownfields Agreement, H&H recommends the building owner or property
management group complete a visual inspection of the accessible portions of the VIMS,
including (but not limited to) the vertical risers and ventilators on the roof and the monitoring
points. H&H recommends annual inspections be documented and kept on record to be provided
to DEQ upon request.

6.0 Reporting
A VIMS installation completion report (sealed by a NC PE) documenting installation activities
associated with the VIMS will be submitted to DEQ following system installation and
confirmation of system effectiveness (as discussed in Section 4.0). The report will include
summaries of VIMS installation and inspection activities, as -built drawings signed and sealed by
a NC PE, summaries of effectiveness testing and pre -occupancy monitoring activities/results,
representative photographs, SDSs of materials used in construction, and inspection documents.
The report will also include a statement provided by the Engineer certifying that the VIMS was
installed in accordance with the DEQ-approved VIMP and is protective of public health (as
defined in Section 1.2), as evidenced by the VIMS inspections performed by the Engineer (or
Engineer's designee), results of effectiveness testing and monitoring, and QA/QC measures as
described in this VIMP. Deviations from the DEQ-approved VIMP will be identified in the
report.
The pending Brownfields Agreement is anticipated to include standard land use restrictions that
indicate the proposed Site building shall not be occupied prior to DEQ written compliance
approval for the installation and performance of the VIMS as documented in the installation
report. However, we understand that DEQ may provide conditional approval with submittal of a
data summary package in lieu of the final VIMS installation completion report if warranted
based on the timing of the proposed building occupancy date and report review times. No

Notes:
1) NC Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) dated July 2022 and based upon TCR = 1 x 10-6 and THQ = 0.2.
2) Range and mean values of background metals for North Carolina soils taken from Elements in North American Soils by Dragun and Chekiri, 2005. Background Cd and Ag concentrations were taken from Southeastern and Conterminous US soils.
3) EPA Maximum Concentration of Contaminants for the Toxicity Characteristic - CFR Title 40, Chapter I, Part 261, Subpart C, § 261.24 dated October 2022.
Compound concentrations are reported in milligrams per kilograms (mq/kq) unless otherwise noted.
Compound concentrations are reported to the laboratory method detection limits.
With the exception of metals, only constituents detected in at least one sample are shown in the table above.
Bold values exceed Protection of Groundwater PSRGs.
Underlined values exceed the Residential PSRGs.
Raced values exceed the Industrial/Commercial PSRGs
VOCs = volatile organic compounds; SVOCs = semi -volatile organic compounds; OCPs = organochlorine pesticides; RCRA = Resource Conservation RecoveryAct; TCLP = Toxicity Characteristic Leaching Procedure
-- = Not Applicable; ND = Not Detected; NE = Not Established
J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.
CCVH = Continuing Calibration Verification (CCV) is above control limits but within method parameters. Result is considered estimated.
Ab = Partial pattern recognized. Relative percent difference (RPD) between columns is outside of limits and value should be considered an estimate.

Notes:
1) NC Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) dated July 2022 and based upon TCR = 1 x 10-6 and THQ = 0.2.
2) Range and mean values of background metals for North Carolina soils taken from Elements in North American Soils by Dragun and Chekiri, 2005. Background Cd and Ag concentrations were taken from Southeastern and Conterminous US soils.
3) EPA Maximum Concentration of Contaminants for the Toxicity Characteristic - CFR Title 40, Chapter I, Part 261, Subpart C, § 261.24 dated October 2022.
Compound concentrations are reported in milligrams per kilograms (mg/kg) unless othervdse noted.
Compound concentrations are reported to the laboratory method detection limits.
With the exception of metals, only constituents detected in at least one sample are shown in the table above.
Bold values exceed Protection of Groundwater PSRGs.
Underlined values exceed the Residential PSRGs.
1haded values exceed the Industrial/Commercial PSRGs)
VOCs = volatile organic compounds; SVOCs = semi -volatile organic compounds; OCPs = organochlorine pesticides; RCRA = Resource Conservation Recovery Act; TCLP = Toxicity Characteristic Leaching Procedure
-- = Not Applicable; ND = Not Detected; NE = Not Established
J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.
CCVH = Continuing Calibration Verification (CCV) is above control limits but within method parameters. Result is considered estimated.
Ab = Partial pattern recognized. Relative percent difference (RPD) between columns is outside of limits and value should be considered an estimate.

VAPORBLOCK! PLUS TM . .
VBP20
UNDER -SLAB VAPOR / GAS BARRIER
PRODUCT DESCRIPTION
VaporBlock® PIusTI 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® PIusTI 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® PIusT'" 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® PIusT'" 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.
.. Ili RiIIIIIIIII-IM
VaporBlock® PIusTm 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® PIusTm 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® PIusTm 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.

(Note: This example shows multiple options for waterstop 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® PlusTM' 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

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 VaporSealTM
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 112" 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 VaporSeall" 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
VaporSealTM' 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-SEALT""
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-SEALTIM in plastic container for longer
than the time it takes to pour sealant.

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 VaporSealT"' tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® PlusTM' 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" VaporSealTM' 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® PlusTM' when installing screed
supports, utilize non -penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® PlusT". 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.

DN INSTRUCTIONS Ij4p-
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
Usedin Contact with Earth or Granular Fill Under Concrete Slabs. There are specific instructions in this document that go beyond what is stated in
ASTM El643 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.
UNDER -SLAB INSTRUCTIONS:
0 Drago Wrap has been engineered to be installed over a tamped aggregate, sand, or earth base. It is not typically necessary
to have a cushion layer or sand base, as Drago Wrap is tough enough to withstand rugged construction environments.
NOTE: Drago Wrap must be installed with the gray facing the subgrade.
Fig.1: UNDER -SLAB INSTALLATION
® 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. 11. 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.
® 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.

SEAMS: Overlap Drago Wrap a minimum 12 inches and seal with Drago Tape. Make sure the area of adhesion is free
from dust, moisture and frost to allow maximum adhesion of the pressure -sensitive tape.
PIPE PENETRATION SEALING:
• Install Drago Wrap around pipe by slitting/cutting material.
• If void space is minimal, seal around base of pipe with Drago Tape and/or Drago® Sealant and Drago® Sealant Form.
DETAIL PATCH FOR PIPE PENETRATION SEALING:
• Cut a piece of Drago Wrap that creates a 6 inch overlap around all edges of the void space.
• Cut an "X" slightly smaller than the size of the pipe diameter in the center of the detail patch.
• Slide detail patch over pipe, secure tightly.
• Tape down all sides of detail patch with Drago Tape.
• Seal around base of pipe with Drago Tape and/or Drago Sealant and Drago Sealant Form.
Drago Tape should be installed above 40°F. In temperatures below 40°F, take extra care to remove moisture or frost
from the area of adhesion. Ensure that the entirety of all seams are taped with applied pressure to allow for maximum
and continuous adhesion of the pressure -sensitive Drago Tape.
Review Drago Wrap's complete installation instructions prior to installation.

SOIL GAS COLLECTOR MAT FOR
RADON READY NEW CONSTRUCTION
According to the US EPA's model stan-
dards for radon control systems in new
building construction, a means for col-
lecting soil gas should be installed be-
neath the slab.
More and more mitigators and buildiers
are using PDS' soil gas collector mat
because its installation does not entail
any special coordination with plumb-
ers or other site contractors. Low pro-
file mat saves time as it removes the
need for trenching. Just lay radon mat
down around the inside perimeter of
the foundation, secure it with spikes or
landscaping staples, and pour the con-
crete.
SGC mat is superior to other mat sys-
tems because of its thickness and it
has a geotextile fabric cloth surround-
ing the entire mat material. This fea-
ture eliminates the need to lay a plas-
tic 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 quality of the
concrete slab. When SGC mat is in-
stalled below the slab, you're providing
an airspace that intercepts radon --and
other soil gases and vapors --before
it seeps into the building through the
slab. SGC mat also works well as a soil
gas collector beneath crawlspace bar-
rier due to its low -profile.
The 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 col-
lection point. This creates incredible
pressure field extension for post con-
struction system activation. The mat
can support concrete without com-
pressing, yet is extremely lightweight
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
underlying gravel and soil. The natural
airflow through the mat then channels
the radon to the T riser to pipe connec-
tion. From there, hazardous gas can be
vented safely through the roof of the
building.
Another key element of a soil gas col-
lection system is attaching the 4" riser
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 connections or fittings.
common duct tape and caulk does the
trick.

NO TRENCHING
NO BACKFILL
NO VAPOR BARRIER*
It's called SOIL gas mat for a reason,
Place directly on soil or substrate.
Low -profile (1" thick) gas mat
does not require trenching.
j

INSTALLATION INSTRUCTIONS
1. Begin work on the sub grade (soil or gravel) after the final preparation and
before the concrete is poured. Start with T-Riser(s) and work out to ensure
smooth mat placement. Position the T-Riser(s) in appropriate location(s) and
nail down with a 12" steel nail (T Nail) through precut center hole.
2. Slide mat into flat openings on either end of T-riser with a portion of the fab-
ric around the outside. Tape the fabric to the outside of the T-Riser with duct
tape and staple mat to the ground with landscape staples to ensure soil contact
remains during pour stage.
3. Mat is typically laid out in a rectangular loop in the largest area with branch-
es or legs into smaller areas (FREE plan design at www.radon mat.com). There
is no need to trench the mat. Roll out the SGC mat, 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 addi-
ton to corners, tee junctions & ends.
5. 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.
6. 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 ma-
trix of the branch (or overlap 1/2")to the matrix of the main loop. Pull the flter
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.
