Vapor Intrusion Mitigation Plan Selles Bagwell S. Tryon Street & Distribution Street Charlotte, North Carolina
Brownfields Project No. 24008-20-060 H&H Job No. HAN-007
1.0 Introduction

On behalf of HANIMPJV South End NC LLC, Hart & Hickman, PC (H&H) has prepared this
Vapor Intrusion Mitigation Plan (VIMP) for the proposed redevelopment of the Selles Bagwell
Brownfields property (Brownfields No. 24008-20-060) located at S. Tryon Street and Distribution
Street in Charlotte, Mecklenburg County, North Carolina (Site). A Site location map is provided
as Figure 1, and the Site and surrounding area are shown in Figure 2.

The Site consists of the following six (6) contiguous parcels of land that total approximately 4.07
acres:

• Parcel #12104301 (2301 S. Tryon Street) – a 0.455-acre industrial property developed with
a 4,500-square ft office/warehouse building constructed in 1984 and most recently
occupied by Kelly & McArdle Construction;
• Parcel #12104302 (2311 S. Tryon Street) – a 0.563-acre industrial property developed with
a 13,000-square ft office/warehouse building constructed in 1967 and most recently
occupied by Best Tile;
• Parcel #12104303 (2321 S. Tryon Street) – a 1.088-acre industrial property developed with
an 8,900-square ft office/warehouse building constructed in 1959 and most recently
occupied by Interstate Electric;
• Parcel #12104304 (2405 S. Tryon Street) – a 0.497-acre industrial property developed with
a 9,000-square ft duplex office/warehouse building constructed in 1976 and most recently
unoccupied;
• Parcel #12104319 (2300 Distribution Street) – a 0.661-acre industrial property developed
with a 15,508-square ft office/warehouse building constructed in 1966 and most recently
occupied by World of Stone; and

• Parcel # 12104317 (2322-2324 Distribution Street) – a 0.808-acre industrial property
developed with an 11,370-square ft duplex warehouse building constructed in 1964 and
most recently occupied by Charlotte Grill (2324-A) and Pet Wants: Urban Feed Store
(2324-B).

The remaining portions of the Site are developed with a diesel aboveground storage tank (AST)
and dispenser located at Interstate Electric, asphalt paved parking areas and access drives,
landscaped and naturally vegetated areas, and chain-link fencing. Proposed redevelopment for the
Site includes razing the existing Site buildings, which is currently on-going, and constructing a
six-story multi-family residential apartment building with associated parking deck and access
roads. Proposed redevelopment plans are included in Appendix A.

Prior to the development of the on-Site structures listed above, the Site was agricultural land in the
earliest historical resource reviewed, a 1938 aerial photograph. Historically, 2301 S. Tryon Street
was developed with Standard Memorial and Beasley Coal in the 1930s, and a single-family
residence in the 1940s through the 1960s. In the 1960s, the residence was razed, and the parcel
consisted of vacant land until the 1980s. 2311 S. Tryon Street was formerly occupied by Selles
Bagwell and 2300 Distribution Street was occupied by Chase Brass C Copper Inc; a distributing
company, a manufacturer agent company, a tool supplier, and World of Stone Fabricators. 2322-
2324 Distribution Street has historically been occupied by various operations including
distribution, industrial machinery and equipment design/fabrication/installation company, various
cleaning and automotive services, and retail space.

During Phase II Environmental Site Assessment (ESA) activities completed in 2019,
trichloroethylene (TCE) and tetrachloroethylene (PCE) were detected in the groundwater sample
collected from TMW-1 located on the 2300 Distribution St. parcel at concentrations above NCAC
2L Groundwater Quality Standards (2L Standards). During Brownfields assessment activities
completed in 2021, vinyl chloride was detected in TW-4 (32 µg/L) and TW-5 (2.2 µg/L) above
the 2L Standard and DEQ Division of Waste Management (DWM) Residential Groundwater
Screening Level (GWSL) on the 2321 S. Tryon Street parcel. In addition, 1,4-dioxane was
3
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
detected at estimated concentrations (J -value) of 25 J µg/L and 19 J µg/L, respectively, above the
2L Standard of 3 µg/L.

Risk calculator results were calculated for each groundwater sample and the calculated lifetime
incremental carcinogenic risk (LICR) for a residential use scenario for groundwater sample TW-4
was above the acceptable LICR of 1 x 10-4. The calculated LICRs for the remaining groundwater
samples were below the acceptable risk of 1 x 10-4 and the calculated non-carcinogenic Hazard
Index (HI) values were less than 1.

The 2021 Brownfields assessment also included the collection of exterior soil gas and sub-slab
soil gas samples. Benzene was detected in soil gas sample SG-1 (52 µg/m3) at a concentration
exceeding the DWM Residential Sub-Slab and Exterior Soil Gas Screening Level (SGSL). In
addition, TCE was detected in soil gas point SG-1 located in the eastern portion of the Site at a
concentration of 1,400 µg/m3, which exceeds the Residential and Non-Residential SGSLs. TCE
was not detected above the SGSLs in other soil gas samples and was not detected above the
laboratory method detection limits in any other samples with the exception of low-level detections
in the southern corner of the Site. The calculated soil gas LICRs for residential and non-residential
use scenarios were below the acceptable risk of 1 x 10-4 at the Site. In addition, the calculated HI
values at the Site were below the acceptable level of 1.0 with the exception of the SG-1 sample
location which exceeded under both a residential and non-residential use scenario. Analytical data
summary tables and a sample location map are provided in Appendix B.

Based on the potential for vapor intrusion risk at the Site, the PD has proposed to install a passive
vapor intrusion mitigation system in the proposed residential apartment building during
redevelopment activities as a precautionary measure. Installation of the VIMS will satisfy the
following Land Use Restriction (LUR) which is standard language in the Brownfields Agreement:

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 referenced in paragraph 18 below, may be occupied until DEQ determines in writing
that:

i. the building is or would be protective of the building’s users and public health from the
risk of vapor intrusion based on site assessment data, or a site-specific risk assessment
approved in writing by DEQ; or
ii. a vapor intrusion mitigation system (VIMS) has been:
1. designed to mitigate vapors for subgrade building features in accordance with the most
recent and applicable 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, and that said design shall fully protect public health to the satisfaction of a
professional engineer licensed in North Carolina, as evidenced by said engineer’s
professional seal, and shall include a performance monitoring plan detailing
methodologies and schedule, both of which are subject to prior written DEQ approval;
and
2. installed and an installation report is submitted for written DEQ approval that includes
details on any deviations from the system design, as-built diagrams, photographs, and
a description of the installation with said engineer’s professional seal confirming that
the system was installed per the DEQ-approved design and will be protective of public
health.

According to the DWM Vapor Intrusion Guidance: “Risk-based screening is used to identify sites
or buildings likely to pose a health concern, to identify buildings that may warrant immediate
action, to help focus site-specific investigation activities or to provide support for building
mitigation and other risk management options including remediation.” In addition, this VIMP was
prepared to satisfy the vapor intrusion mitigation condition in the pending Brownfields Agreement.
Per the North Carolina Brownfields Property Reuse Act 130A-310.32, a prospective developer,
with the assistance of H&H for this project, is to provide NCDEQ with “information necessary to
demonstrate that ... as a result of the implementation of the brownfields agreement, the brownfields
property will be suitable for the uses specified in the agreement while fully protecting public health
and the environment instead of being remediated to unrestricted use standards.” It is in the context
of these risk-based concepts that H&H’s 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

The VIMP is included in Appendix C (Sheets VM-1, VM-2, VM-2A, VM-3, and VM-4) and will
be used to guide construction of the VIMS. The proposed Site redevelopment plan (Appendix A)
includes one residential apartment building which will be constructed with concrete slab-on-grade
foundations and column foundations. The proposed building will wrap around a multi-story open-
air parking deck which will be constructed on the western portion of the Site. The Level 0 footprint
(ground floor) for the building is approximately 41,729 square feet (sq ft) and the Level 1 footprint
(ground floor) totals approximately 75,613 sq ft with approximately 33,884 sq ft on grade. The
proposed parking garage will include six levels and is mechanically vented on the basement level
with natural ventilation on the above-grade floors. Based on the data provided to H&H at the
issuance of this plan, the electrical room, storage room, and bike storage room proposed in the
central and northern portions of the parking garage have been included in the VIMS.

The VIMP includes installation of Vaporblock® Plus 20 (VBP20) vapor barrier manufactured by
Raven Industries (Raven) beneath the ground level concrete slab of each building. VBP20 is an
ASTM-certified 20-mil, multi-layer, chemically resistant vapor barrier, designed to prevent the
migration of VOCs. Technical specifications and installation instructions obtained from Raven
for the VBP20 vapor barrier are provided in Appendix D.

The VIMP specifies that the vapor barrier will be installed per manufacturer installation
instructions (Appendix D). Briefly, VBP20 will be installed by the construction contractor to
cover the ground surface below the entire area of the proposed ground floor slab and below the
basement-level portions of the building that are below the residential units or connect to the
residential portion of the building. The exterior edges of the VBP20 will be attached and sealed
to existing concrete utilizing VaporSeal™ tape or Butyl Seal 2-sided tape. Seams within the
building footprint will have a minimum 12-inch overlap and will be sealed with VaporSeal™ tape
with the option of supplementing the seal with 2-sided Butyl Seal tape. Small puncture holes will
be sealed with VaporSeal™ tape or Pour-N-Seal™, and larger holes, tears, or damage will be
repaired using a patch that overlaps the damaged area and then will be taped along the seams. In
areas where utility penetrations (i.e., piping, ducts, etc.) are present and the use of taping is not
7
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
practical or deemed as “ineffective” by the design engineer, the Pour-N-Seal™ method will be
used to form an airtight seal around the penetrations. Locations where Pour-N-Seal™ is used will
be documented during the field inspections and noted on the as-built drawings.

Note that other vapor barrier bonding products (i.e., tapes, epoxies, etc.) that do not contain
compounds of concern for the Site and are approved by the engineer and by the vapor barrier
manufacturer may be used to seal the liner. Please also note that an equivalent vapor barrier
approved by the engineer which meets the criteria specified in Sheet VM-2 of the VIMP may also
be used by the installation contractor, such as Drago Wrap® manufactured by Stego Industries. If
Drago Wrap® is selected for use, DEQ will be notified in writing and specification and installation
instruction sheets will be provided. In the event that alternate equivalent vapor barrier bonding
products or vapor barrier liner (other than VBP20 or Drago Wrap®) are selected, DEQ approval
will be requested in writing prior to installation.

The VIMP also includes installation of an enhanced passive mitigation system beneath the building
slab to reduce the potential for vapor intrusion into the proposed building by vapor extraction.
Vapor extraction will be accomplished using wind-driven turbine ventilators, vapor
collection/conveyance piping, and horizontal perforated collection piping to collect vapor from
beneath the slab of the building and discharge the vapor through exhaust stacks installed above the
building roofs. Product specifications for the turbine ventilators and slotted collection piping are
included in Appendix D.

The VIMP includes Empire Model TV04SS (stainless steel) turbine ventilator fans (or a design
engineer approved alternate) installed on the discharge end of the exhaust stacks on the roof. The
exhaust discharge locations shall be a minimum of 10 feet from any operable opening or air intake
for the building and a minimum of 2 feet above the roofline. For system redundancy, the vent
systems below the slab-on-grade spaces are interconnected. The interconnected systems will allow
for continued sub-slab depressurization below the building slabs in the event that active fans are
installed in the future or a turbine ventilator is damaged between yearly inspections completed by
building maintenance.

https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
To enhance sub-slab vapor transmission and collection effectiveness, a uniform layer of high
permeability stone (clean #57 or similar stone) will be installed directly below the concrete slabs
to allow for air movement beneath the entirety of the slabs. Sub-slab piping will consist of 3-inch
diameter Schedule 40 (SCH 40) PVC piping installed within the high permeability stone layer.
The thickness of the high permeability stone around the piping will extend a minimum of 1-inch
above the piping and a minimum of 1-inch below the piping (for example, 5 inches of gravel
around a 3-inch pipe). In areas without piping, a minimum thickness of 4 inches of clean stone is
required.

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

In the event the system needs to be activated with electric fans (see Section 4.0), the VIMP includes
vacuum measuring points (depicted in Sheets VM-3 and VM-4). The vacuum measuring points
will be used to measure the pressure differential between indoor air and the sub-slab, should
electric fans be needed. To prevent disrupting building operations in the future, the vacuum
measuring point access ports are located in areas that do not disturb building occupants such as
exterior access ports and interior hallways and mechanical rooms (see Sheets VM-3 and VM-4 in
Appendix C).

3.0 Quality Assurance / Quality Control

For quality assurance and quality control purposes, inspections will be conducted for each section
of slab during the following phases of VIMS installation activities:

• Inspection of the base course gravel layer, sub-slab piping layout, and monitoring points
prior to installing the vapor liner;
• Inspection of the vapor liner prior to pouring concrete and vapor liner along retaining walls;
• Inspection of above-grade vertical riser piping; and
• Inspection of turbine fan installations and riser pipe connections.

Please note that an additional inspection will be conducted if the VIMS is activated to verify that
the electric fans are functioning properly. Each inspection will be performed by, or under direction
of, the design engineer certifying the VIMP. No component of the VIMS shall be covered until
an inspection is completed. The inspections will include field logs and photographs for each
section of slab. Locations where multiple penetrations are present and where Pour-N-Seal™ is
used will be photographed, noted on the field logs, and shown on the as-built drawings. The use
of hollow piping by contractors to support their utilities in preparation for concrete pours is not
permitted. Contractors will be instructed to remove any hollow piping observed during the field
inspections. When possible, the engineer certifying the report, or designee, will provide DEQ with
48 hours notice prior to conducting the inspections.

4.0 Post-Construction System Effectiveness Testing

Influence Testing
Following installation of the horizontal extraction piping, vapor barrier, and concrete slab pours,
but prior to building occupancy, influence testing will be conducted on the VIMS vent piping
network to confirm that the VIMS will provide proper vacuum influence below the slab, if the
system is activated with electric fans in the future. For the influence test, variable speed vapor
extraction fans will be attached to the vertical risers and vacuum will be measured at the extraction
fan locations and at the permanent and temporary vacuum measuring points for the section of slab
being evaluated.

The results of the influence test will be submitted to DEQ with the construction completion report.
If modifications to the VIMS are required to achieve vacuum influence of 4 pascals (0.016-inches
water column), additional influence testing will be completed to evaluate the system modifications.
Following successful influence testing, the temporary vacuum measuring points will be
abandoned.

Sub-Slab Gas Sampling
Upon completion of successful influence testing and prior to occupancy of the Site building, sub-
slab soil gas samples will be collected from beneath the apartments and amenity areas. The sub-
slab soil gas samples will be collected from select permanent vacuum measuring points as shown
on Sheet VM-3 and VM-4 in Appendix C. Sub-slab soil gas sampling will be completed as
outlined below:

Six sub-slab samples will be collected from Level 0 and four sub-slab samples will be collected
from Level 1 of the building footprint. The initial sub-slab soil gas sampling event will be
conducted after a minimum of one week following the installation of the turbine ventilator fans.
The sub-slab soil gas sample locations will be confirmed with DEQ prior to the sampling event.

During each sub-slab soil gas sampling event, one duplicate sub-slab soil gas sample will be
collected for quality assurance/quality control (QA/QC) purposes. The duplicate will be collected
from one of the measuring points using a stainless-steel sample “T” fitting which allows two vapor
11
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
samples to be collected simultaneously from a single measuring point. The vacuum measuring
points will be sampled by securing an expandable cap with a sample port (i.e., an Ex-Cap) into the
vacuum measuring point to create an air-tight seal. The sub-slab vapor sample will then be
collected using the recommended procedures presented in the DWM VI Guidance.

Prior to sample collection, a leak test will be performed on each vacuum measuring point location
by placing a shroud around the sealed sampling point and sample train including the Summa
canister, flooding the air within the shroud with helium gas, then purging soil gas from the
sampling point with an electric air pump or syringe and collecting the purged vapor into a Tedlar®
bag. A helium gas detector will be used to measure helium concentrations within the shroud and
the Tedlar® bag sample. The leak test will be considered successful if the helium concentration
measured in the soil gas purged from the sampling point and collected into the Tedlar® bag is less
than 10% of the concentration measured within the shroud. H&H field personnel will record the
results of the helium leak test in field documentation. In total, a minimum of 3 volumes will be
purged from the sample train prior to and during the leak test.

The sub-slab soil gas samples will be collected in 1-liter Summa canisters at 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 on the chain-of-custody and within the field notes. The
vacuum in each canister at the conclusion of the sampling event must remain above 0 inches of
mercury (in Hg), and ideally around 5 in Hg, to allow for proper laboratory analysis of the sample.

The sub-slab soil gas samples will be submitted to a qualified laboratory under standard chain of
custody protocols for analysis of the full list of VOCs by EPA Method TO-15. The laboratory will
be instructed to report J-flag concentrations for each sample, to report received canister vacuum,
and to include naphthalene in the TO-15 analyte list. 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 Residential Vapor Intrusion SGSLs.

Upon receipt of the sub-slab soil gas sample analytical results, H&H will use the most current
version of the DEQ Risk Calculator to evaluate potential vapor intrusion risks for a residential use
12
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
scenario based on the proposed residential apartment development. In the case where calculated
cumulative risks are less than 1x10-4 for potential carcinogenic risks and below a hazard index of
1 for potential non-carcinogenic risks, a report will be submitted to DEQ to document system
effectiveness.

Post-occupancy sub-slab soil gas sampling will be completed approximately 6 months following
the pre-occupancy sampling event and one additional event will be completed approximately 6
months later, for a total of three sampling events (including pre-occupancy sampling). The sub-
slab sampling events will be completed using the methods discussed above. Following the second
post-occupancy sampling event with results indicating consistent or decreasing concentrations
within acceptable risk levels, a request to terminate sampling will be submitted for DEQ approval.

Note that the generic sub-slab soil gas to indoor air attenuation factor that is the basis for DEQ risk
calculations is very conservative and is intended to estimate a potential upper-bound indoor air
concentration accounting for temporal variability. DEQ DWM VI Guidance indicates that if soil
gas concentrations do not exceed acceptable risk levels, typically no further investigation is
necessary. However, as a conservative approach, this VIMP includes completion of an initial
indoor air event concurrent with the pre-occupancy sub-slab soil gas sampling event. Based on
the pre-occupancy influence testing, sub-slab soil gas, and indoor air results, select indoor air
sample locations for the first post-occupancy indoor air sampling event will be submitted for DEQ
approval. If the first post-occupancy indoor air event indicates consistent or decreasing
concentrations within acceptable risk levels, a request to terminate indoor air sampling will be
submitted for DEQ approval. If indoor air sampling is required for future post-occupancy events,
it will be conducted semi-annually in concurrence with the sub-slab soil gas sampling.

If indoor air sampling is terminated, but calculated cumulative risks for sub-slab samples collected
during future events are greater than 1x10-4 for potential carcinogenic risks and/or above a hazard
index of 1 for potential non-carcinogenic risks, additional indoor air sampling will be completed.
Please note that prior to proceeding with indoor air sampling the sub-slab soil gas data will be
reviewed to confirm that background sources (e.g., building materials) are not influencing
13
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
cumulative risks. If background sources are identified and confirmed, DEQ will be notified and
indoor air sampling will not be performed with written DEQ approval.

The results of sub-slab vapor sampling completed at the Site will be reported to DEQ, as described
in Section 7.0. The building shall not be occupied until the results of the initial, pre-occupancy
sub-slab vapor sampling and indoor air sampling are submitted to DEQ and written approval for
occupancy is obtained from DEQ.

Indoor Air Sampling
The building is intended to be occupied shortly following completion and initialization of the
HVAC system. As discussed with DEQ, there is typically insufficient time before occupancy to
wait for the HVAC system to become operational prior to indoor air sampling. Therefore, the pre-
occupancy indoor air sampling event will be conducted following construction and completion of
the VIMS including a minimum of one week with operational turbine ventilators. Prior to indoor
air sampling, H&H will obtain DEQ approval to proceed with the sampling and provide a statement
confirming that the portion of the building being sampled is substantially complete (e.g., windows
and doors installed and sealed) with no openings to outdoor air which could potentially bias the
indoor air data in the area being sampled. During the pre-occupancy sampling event, three indoor
air samples will be collected on Level 0 and two indoor air samples will be collected on Level 1
at the approximate locations depicted on VM-3 and VM-4.

The indoor air samples will be collected in accordance with the DWM VI Guidance, using 6-liter
individually-certified Summa canisters over a 24-hour period and analyzed for select VOCs by
EPA Method TO-15. The VOCs for the select analyte list will be determined based on the
compounds detected within the sub-slab soil gas samples, and per discussion between H&H and
DEQ. The intake for each indoor air Summa canister will be placed at a height consistent with the
breathing zone. For QA/QC purposes, one duplicate 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.

Periodic checks will be conducted by H&H to monitor the pressure within the Summa canisters to
confirm adequate sample volume is collected. The vacuum of the Summa canisters will be
measured at the start and end of the sampling event and will be recorded on the chain-of-custody
and field notes. The vacuum at the end of the sampling event should remain at or above
approximately -5 inches of mercury (in Hg), as measured with the field vacuum gauge. In no
instance shall the canister vacuum reach 0 in Hg.

Following sample collection, the samples will be shipped to the laboratory under standard chain
of custody protocol. The analytical laboratory will be instructed to report J-flag concentrations for
each sample. In addition, the laboratory will be requested to report results to reporting limits below
the DEQ Residential Vapor Intrusion Indoor Air Screening Levels (IASLs). Per standard
procedure, the laboratory will report the vacuum levels of the canisters upon receipt by the
laboratory.

Note, new construction materials, such as paint, carpet, etc., which could be sources of VOCs in
indoor air, may cause interference with Site-specific compounds during indoor air sampling.
Therefore, the construction contractor will be requested to provide safety data sheets (SDSs) for
materials used during construction and the SDSs will be submitted to DEQ.

Based upon the results of the indoor air sampling, H&H will make recommendations in general
accordance with the DWM VI Guidance. It is anticipated that the recommendations will consist
of one of the following:

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

• Additional indoor air sampling is warranted to confirm that the VIMS is effective (per the
DWM VI Guidance, in the case where calculated cumulative risks are greater than 1x10-4
for potential carcinogenic risks or above a hazard index of 1 for potential non-carcinogenic
risks). 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).

Please note that DEQ may require additional indoor air sampling to confirm that the VIMS is
effective if results suggest a completed vapor intrusion pathway, even if cumulative risk is below
a LICR of 1x10-4 or HI of 1. Prior to completing additional indoor air sampling, an evaluation of
potential background sources will be completed and inspections will be performed to determine if
preferential vapor intrusion pathways may exist.

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(s), 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(s). If the system were
transitioned to an active system in the future, a work plan will be submitted to DEQ to document
a schedule for additional monitoring, such as annual vacuum measurements.

Sub-Slab Gas and Indoor Air Sampling Reporting
A report of the sub-slab gas sampling and indoor air sampling will be submitted to DEQ with the
construction completion report for the proposed building. If additional indoor air sampling is
required based upon the recommendations above, a report of the indoor air sampling will be
submitted to DEQ following completion of the sampling and receipt of the analytical data.

Following receipt of analytical results, the laboratory report will be reviewed and DEQ will be
notified in the event that TCE concentrations in indoor air (if warranted) or sub-slab indicate
potential vapor intrusion pathways may exist. In accordance with the DEQ DWM TCE Indoor Air
Inhalation Immediate Action Levels and Response guidance (dated July 2019), DEQ will be
notified within 24 hours (1 business day) of receipt of the laboratory data if TCE is detected at a

concentration exceeding 2.1 µg/m3 (if indoor air is collected). DEQ will also be notified prior to
report submittal if sub-slab and indoor air samples indicate a completed pathway exists to discuss
whether additional sampling or other measures are warranted.

17
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Hanover Company - HAN/HAN-007 Hanover South End/Brownfields/VIMP/Report/24008 - Selles Bagwell_VIMP_S Tryon Apartments.docx
5.0 Post-Occupancy Testing

The VIMS is proposed as an enhanced passive system which will utilize sub-slab vapor extraction
through vapor extraction piping and wind-driven turbine ventilators on the roof. As such, post-
occupancy differential pressure testing is not anticipated. If the VIMS is converted to an active
system based on results of post-construction and pre-occupancy sub-slab gas and/or any indoor air
assessment results, vapor mitigation system modifications and plans for additional indoor air
sampling and long-term differential pressure monitoring across the slab will be submitted to the
DEQ Brownfields Program for approval prior to implementation. Specifications for the potential
fan to be used if conversion to the active system is deemed necessary are included in Appendix D.
However, a different fan may be specified by the design engineer based on the influence testing
results.

As discussed above, post-occupancy sub-slab soil gas sampling will be completed approximately
6 months following the pre-occupancy event and then one additional event 6 months later. Based
on the pre-occupancy influence testing, sub-slab soil gas, and indoor air results, select indoor air
sample locations for the first post-occupancy indoor air sampling event will be submitted for DEQ
approval. If the first post-occupancy indoor air event indicates consistent or decreasing
concentrations within acceptable risk levels, a request to terminate indoor air sampling will be
submitted for DEQ approval. If indoor air sampling is required for future post-occupancy events,
it will be conducted semi-annually in concurrence with the sub-slab soil gas sampling. The
sampling events will be completed using the methods discussed above. If semi-annual event
results indicate consistent or decreasing concentrations within acceptable risk levels, a request to
terminate sampling will be submitted for DEQ approval.

6.0 Future Tenants & Building Uses

The future use of the proposed Site buildings includes residential apartments. After occupancy of
the Site building, the building maintenance department will maintain the vapor mitigation piping
and ventilators. If vapor mitigation components are damaged or need to be altered for building
renovations, the building management will be instructed to contact the maintenance department.
The maintenance department shall contact a North Carolina licensed Professional Engineer to
oversee or inspect the activities, and a report shall be submitted to DEQ detailing the repairs or
alterations. To aid in identification of the vapor mitigation piping, the piping will be labeled with
“Vapor Mitigation – Contact maintenance”, or similar language, on all accessible piping at
intervals of no greater than 10 linear feet.

Future VIMS maintenance and upkeep will be the responsibility of the property management group
or building owner. As part of the annual Land Use Restriction Update submittal, H&H
recommends the building owner or management complete a visual inspection of the exposed
components of the system 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.

7.0 Reporting

A construction 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, effective, operating properly, and protective of human health from
potential vapor intrusion of known Brownfields property contaminants. The report(s) will include
a summary of VIMS installation activities such as representative photographs and as-built
drawings, QA/QC measures, SDSs of materials used in construction, VIMS effectiveness testing
results, and inspection documents. The report will also include an engineer’s statement as to
whether the VIMS was installed in accordance with the DEQ approved VIMP and is fully
protective of public health as defined in Section 1.0, and as evidenced by the VIMS inspections
performed by the engineer or engineer’s designee, results of the influence testing, results of the
analytical testing, and QA/QC measures as described in this VIMP. Deviations from the approved
design will be provided in the report. Multiple reports may be submitted depending on the
construction schedule of the building.

Prior to occupancy of the building, the results of the influence testing, sub-slab vapor sampling,
and indoor air sampling will be submitted to the Brownfields Program. After each additional post-
construction sub-slab vapor sampling event (and indoor air sampling, if completed), a brief report
will be submitted to DEQ to document the sampling activities and results.

1.THIS VAPOR MITIGATION PLAN IS INTENDED TO BE USED FOR DIRECTION OF VIMS COMPONENT INSTALLATION ONLY AND IS NOT INTENDED TO GUIDE CONSTRUCTION OF BUILDING
STRUCTURAL COMPONENTS. CONSTRUCTION CONTRACTOR SHALL VERIFY CONSISTENCY OF VIMS DETAILS WITH APPLICABLE STRUCTURAL, ARCHITECTURAL, MECHANICAL, & PLUMBING PLANS
AND RESOLVE ANY INCONSISTENCIES PRIOR TO VIMS INSTALLATION.
2.VIMS VAPOR LINER SHALL BE VAPORBLOCK PLUS 20 (VBP20) 20-MIL VAPOR LINER MANUFACTURED BY RAVEN INDUSTRIES (RAVEN). AS AN ALTERNATIVE, DRAGO WRAP 20-MIL VAPOR LINER
MANUFACTURED BY STEGO INDUSTRIES, LLC (STEGO) CAN BE USED, PENDING APPROVAL BY THE ENGINEER.
NOTE THAT ONE VAPOR LINER PRODUCT AND ASSOCIATED ACCESSORIES MUST BE USED THROUGHOUT EACH SYSTEM. TWO DIFFERENT VAPOR LINER PRODUCTS SHOULD NOT BE SEALED
TOGETHER. THE VAPOR LINER SHALL BE INSTALLED AS SPECIFIED HEREIN AND PER MANUFACTURER INSTALLATION INSTRUCTIONS TO CREATE A CONTINUOUS LINER BELOW MITIGATED AREAS,
AND ALONG RETAINING WALLS AND SLAB-ON-GRADE FOLDS WITHIN THE EXTENT OF VAPOR LINER BOUNDARY. A MINIMUM 4-INCH THICK BASE COURSE CONSISTING OF CLEAN #57 STONE
(WASHED WITH NO FINES) SHALL BE INSTALLED BENEATH THE VIMS VAPOR LINER. A SIMILAR HIGH PERMEABILITY STONE MAY BE USED, PENDING APPROVAL BY THE ENGINEER.
THE VAPOR LINER SHALL BE PROPERLY SEALED IN ACCORDANCE WITH THE MANUFACTURER INSTALLATION INSTRUCTIONS AS SPECIFIED IN THESE DRAWINGS TO FOOTERS, SLAB STEPS,
RETAINING WALLS, PENETRATIONS (SUCH AS PIPE PENETRATIONS), OR OTHER BUILDING COMPONENTS WITHIN THE VIMS EXTENTS. VAPOR LINER SHALL BE INSTALLED UNDER CMU WALLS
WHICH SUPPORT OCCUPIED ENCLOSED SPACES. ANY LOCATIONS AT WHICH POUR-N-SEAL OR EQUIVALENT ARE USED WILL BE DOCUMENTED DURING INSPECTIONS.
VAPOR BARRIER SHALL BE INSTALLED ON SLABS, WALLS, AND OTHER STRUCTURAL COMPONENTS WHICH COME IN CONTACT WITH BOTH AN OCCUPIABLE ENCLOSED SPACE AND SOIL.
VAPOR BARRIER SHALL BE TERMINATED ALONG THE EXTERIOR WALL AT EXTERIOR GRADE IN LOCATIONS WHERE EXTERIOR SOIL GRADE IS ABOVE THE FINISHED GRADE OF THE INTERIOR
OCCUPIABLE SPACE.
ALL CONCRETE BOXOUTS, INCLUDING BUT NOT LIMITED TO SHOWER/BATH TUB DRAINS, SHALL HAVE A CONTINUOUS VAPOR LINER INSTALLED BELOW.
3.SUB-SLAB SLOTTED VAPOR COLLECTION PIPE SHALL BE THREADED FLUSH JOINT 3" SCH 40 PVC PIPE WITH 0.020" TO 0.060" SLOT WIDTH AND 1/8" SLOT SPACING. AN ALTERNATE SLOT PATTERN,
OR SCH 40 PVC PERFORATED PIPE WITH 5/8" OR SMALLER DIAMETER PERFORATIONS, OR SOIL GAS COLLECTOR MAT (1" X 12"), WITH SIMILAR AIR FLOW CHARACTERISTICS TO THE SLOTTED PIPE
MAY BE USED PENDING APPROVAL BY THE DESIGN ENGINEER. IF CIRCULAR PIPE IS USED, A VENT CAP SHOULD BE INSTALLED ON THE OPEN PIPE END. PVC PIPE JOINTS SHOULD BE DRY-FITTED
BELOW THE SLAB OR CONNECTED WITH SCREWS. SLOTTED COLLECTION PIPING SHALL BE SET WITHIN A MINIMUM 5” BASE COURSE LAYER, WITH APPROXIMATELY 1” OF BASE COURSE
MATERIAL BELOW THE PIPING.
4.3" SCH 40 PVC SHALL BE INSTALLED TO CONNECT EACH SLAB PENETRATION LOCATION TO THE EXHAUST DISCHARGE POINT. ABOVE-SLAB RISER DUCT PIPE RUNS BETWEEN THE SLAB
PENETRATION AND THE ROOFTOP EXHAUST DISCHARGE SHALL BE INSTALLED PER APPLICABLE BUILDING CODE AND AS SPECIFIED IN THE CONSTRUCTION DOCUMENTS AND DRAWINGS.
VERTICAL RISER PIPING SHALL BE CONNECTED USING AIR-TIGHT FITTINGS (NO-HUB FITTINGS AND PIPES ARE ACCEPTABLE). VERTICAL RISER PIPING MUST BE INSTALLED PER 2018 NORTH
CAROLINA STATE PLUMBING CODE. VIMS BELOW AND ABOVE GRADE SOLID PIPING SHALL NOT BE TRAPPED AND SHALL BE SLOPED A MINIMUM OF 1/8 UNIT VERTICAL BY 12 UNITS HORIZONTAL
(1% SLOPE) TO GRAVITY DRAIN. BENDS, TURNS, AND ELBOWS IN VERTICAL RISER PIPES SHALL BE MINIMIZED FROM THE SLAB TO THE ROOFTOP.
5.EXHAUST DISCHARGE LOCATIONS SHALL BE A MINIMUM OF 10 FT FROM ANY OPERABLE OPENING OR AIR INTAKE INTO THE BUILDING AND 20 FT FROM THE GROUND ELEVATION. AN
ELECTRICAL JUNCTION BOX (120V REQUIRED) FOR OUTDOOR USE SHALL BE INSTALLED WITHIN 5FT OF THE EXPOSED RISER PIPE PRIOR TO THE EXHAUST DISCHARGE FOR POTENTIAL FUTURE
CONVERSION TO ELECTRIC FANS, IF REQUIRED. A MINIMUM 2 FT SECTION OF RISER PIPE MUST BE INSTALLED IN A VERTICAL ORIENTATION IMMEDIATELY PRIOR TO THE EXHAUST DISCHARGE
WITH FLANGES OR UNIONS TO ALLOW ROOM FOR A POTENTIAL FUTURE ELECTRIC FAN, IF REQUIRED. ALL WIRING AND ELECTRICAL SHALL BE INSTALLED PER APPLICABLE BUILDING AND
ELECTRICAL CODES.
6.ABOVE-SLAB ACCESSIBLE RISER DUCT PIPING SHALL BE PERMANENTLY IDENTIFIED BY MEANS OF A TAG OR STENCIL AT A MINIMUM OF ONCE EVERY 10-LINEAR FT WITH "VAPOR MITIGATION.
CONTACT MAINTENANCE". LABELS SHALL ALSO BE FIXED TO THE TURBINE FANS IN AN ACCESSIBLE LOCATION ON THE ROOFTOP.
7.MONITORING POINTS SHALL CONSIST OF 2-INCH DIAMETER SCH 40 PVC PIPE WITH A 90-DEGREE ELBOW TO FORM AN “L” SHAPE. A MINIMUM OF 6” SECTION OF PIPING SHALL BE SET WITHIN
THE BASE COURSE LAYER WITH AN OPEN ENDED PIPE OR PIPE PROTECTION SCREEN AT THE TERMINATION. THE PIPE TERMINATION SHALL BE SET WITHIN THE BASE COURSE LAYER. THE
HORIZONTAL PIPING SHALL BE SLOPED A MINIMUM OF 1/8 UNIT VERTICAL BY 12 UNITS HORIZONTAL (1% SLOPE) TO GRAVITY DRAIN TOWARDS THE PIPE TERMINATION AND PREVENT
MOISTURE FROM COLLECTING AT THE 90-DEGREE ELBOW. A 4-INCH DIAMETER ADJUSTABLE FLOOR CLEAN-OUT (ZURN INDUSTRIES MODEL #CO2450-PV4, OR EQUIVALENT) SHALL BE INSTALLED
AND SET FLUSH WITH THE FINISHED CONCRETE SURFACE. MONITORING POINT INTAKE SHALL BE MINIMUM 5-FT FROM EXTERIOR FOOTING.
8.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS SHALL USE "LOW OR NO VOC" PRODUCTS AND MATERIALS, WHEN POSSIBLE, AND SHALL NOT USE PRODUCTS CONTAINING THE
COMPOUNDS TETRACHLOROETHENE (PCE) OR TRICHLOROETHENE(TCE). THE CONSTRUCTION CONTRACTOR AND SUB-CONTRACTORS SHALL PROVIDE SAFETY DATA SHEETS (SDS) TO THE
ENGINEER FOR THE PRODUCTS AND MATERIALS USED FOR CONSTRUCTION OF THE VIMS.
9.IN INSTANCES WHERE A THICKENED FOOTING OR RETAINING WALL IS NOT SPECIFIED AT THE EXTENT OF VAPOR LINER, A THICKENED SLAB OR FOOTER SHALL BE INSTALLED BY THE CONTRACTOR
THAT INCLUDES A SOIL SUBBASE TO CREATE A CUT-OFF FOOTER AT THE EXTENT OF VAPOR LINER. THE ADDITIONAL THICKENED SLAB OR FOOTER SHALL NOT ALLOW FOR CONTINUOUS GRAVEL
BETWEEN THE VIMS EXTENTS AND EXTERIOR PORTIONS OF THE BUILDING WITH AT LEAST 12" SEPARATION OF ADJACENT GRAVEL BEDS. THE THICKENED SLAB OR FOOTER SHALL BE A
MINIMUM OF 5" GREATER IN THICKNESS THAN THE SURROUNDING SLAB.
10.CONSTRUCTION CONTRACTORS AND SUB-CONTRACTORS SHALL AVOID THE USE OF TEMPORARY FORM BOARDS THAT PENETRATE THE VAPOR LINER WHERE POSSIBLE. IF TEMPORARY FORM
BOARDS ARE USED, THE SIZE AND NUMBER OF PENETRATIONS THROUGH THE VAPOR LINER SHALL BE LIMITED AND SMALL DIAMETER SOLID STAKES (I.E. METAL STAKES) SHALL BE USED. IN ALL
CASES, AS FORM BOARDS ARE REMOVED, THE CONTRACTOR OR SUB-CONTRACTORS SHALL RESEAL ALL PENETRATIONS IN ACCORDANCE WITH VAPOR LINER MANUFACTURER INSTALLATION
INSTRUCTIONS.
11.INSPECTIONS: INSPECTIONS OF EACH COMPONENT OF THE VIMS SHALL BE CONDUCTED BY THE ENGINEER, OR ENGINEER'S DESIGNEE, TO CONFIRM VIMS COMPONENTS ARE INSTALLED PER
THE APPROVED DESIGN. THE REQUIRED INSPECTION COMPONENTS INCLUDE: (1) INSPECTION OF SUB-SLAB PIPING LAYOUT, (2) GRAVEL PLACEMENT, AND (3) MONITORING POINT PLACEMENT
PRIOR TO INSTALLING VAPOR BARRIER; (4) INSPECTION OF VAPOR BARRIER PRIOR TO POURING CONCRETE; (5) INSPECTION OF ABOVE-GRADE PIPING LAYOUT; AND (6) INSPECTION OF TURBINE
FANS AND RISER DUCT PIPE CONNECTIONS. NO VIMS COMPONENTS SHALL BE COVERED BEFORE INSPECTIONS ARE COMPLETED. INSPECTIONS WILL BE COMBINED WHEN POSSIBLE DEPENDING
ON THE CONSTRUCTION SEQUENCE/SCHEDULE. THE CONSTRUCTION CONTRACTOR(S) SHALL COORDINATE WITH THE ENGINEER TO PERFORM THE REQUIRED INSPECTIONS. A MINIMUM
48-HOUR NOTICE SHALL BE GIVEN TO THE ENGINEER PRIOR TO THE REQUIRED INSPECTION(S).
12.PIPE SLEEVES, IF USED, SHALL BE PROPERLY SEALED TO PREVENT A PREFERENTIAL AIR PATHWAY FROM BELOW THE SLAB INTO THE BUILDING. REFER TO TO STRUCTURAL DRAWINGS FOR
DETAILS ADDRESSING VIMS PIPING.
13.IF WATERPROOFING IS PRESENT ALONG AREAS WITH VAPOR BARRIER, THE VAPOR BARRIER SHALL BE INSTALLED BETWEEN WATERPROOFING AND ANY DRAINAGE FEATURES INCLUDING
DRAINAGE MATS WHERE IT OVERLAPS (SEE DETAIL #16). THE INSTALLER SHALL CONFIRM THAT THE WATERPROOFING PRODUCTS AND SEALANTS USED DURING CONSTRUCTION ARE
COMPATIBLE WITH THE SPECIFIED VAPOR BARRIER.

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 four to eight slices about 3/8” less than the diameter of the pipe.
C) Force the square over the pipe leaving the tightly stretched cut area around the bottom of the pipe with approximately a 1/2” of the boot material running vertically up the pipe. (no more than a 1/2” of stretched boot material is recommended)
D) Once boot is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in between the two layers. Secure boot down firmly over the membrane taking care not to have any large folds or creases.
E) Use VaporBoot Tape or VaporSeal™ Tape to secure the boot to the
pipe.
VaporBoot Tape (option) – fold tape in half lengthwise, remove half of the release liner and wrap around the pipe allowing 1” extra for overlap sealing. Peel off the second half of the release liner and work the tape outward gradually forming a complete seal.
VaporSeal™ Tape (option) - Tape completely around pipe overlapping the VaporBlock® Plus™ square to create a tight seal against the pipe.
F) Complete the process by taping over the boot perimeter edge with VaporSeal™ Tape to create a monolithic membrane between the surface of the slab and gas/moisture sources below and at the slab perimeter. (Fig. 4 & 6)

B) Mark where to cut openings and cut four to eight slices about
3/8” less than the diameter of the penetration for each.
C) Force patch material over penetration to achieve a tight fit and
form a lip.
D) Once patch is positioned, seal the perimeter to the membrane
by applying 2-sided Raven Butyl Seal Tape in-between the two
layers. (Fig. 8)
E) After applying Raven Butyl Seal Tape between the patch and
membrane, tape around each of the penetrations and the patch
with VaporSeal™ 4” tape. (Fig. 9) For additional protection apply
POUR-N-SEAL™ or an acceptable polyurethane elastomeric
sealant around the penetrations. (Fig. 10)

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

VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired prior
to placing concrete. When patching small holes, simply cut a 12” long
piece of 12” wide VaporSeal™ tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® Plus™ around pipe penetrations,
vertical columns, electrical ducts and other obstructions, you will
find it necessary to cut it to the nearest outside edge. This cut can
be easily sealed with 12” wide VaporSeal™ tape, by simply centering
it over the cut, 6” on either side. Once the tape is placed correctly,
apply pressure to assure a complete seal (Fig. 16).
Reminder Note: All holes or penetrations through the membrane will need
to be patched with 12” VaporSeal™ Tape.

2.1. When installing reinforcing steel and utilities, in addition to the
placement of concrete, take precaution to protect VaporBlock®
Plus™. Carelessness during installation can damage the most
puncture–resistant membrane. Sheets of plywood cushioned with
geotextile fabric temporarily placed on VaporBlock® Plus™ provide
for additional protection in high traffic areas including concrete
buggies.
2.2. Use only brick-type or chair-type reinforcing bar supports to protect
VaporBlock® Plus™ from puncture.
2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be
avoided, each individual hole must be repaired per section 1.7.
2.4. To avoid penetrating VaporBlock® Plus™ when installing screed
supports, utilize non-penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® Plus™. If this cannot be avoided, each individual hole
must be repaired per figures 14-15.
2.5. If a cushion or blotter layer is required in the design between
VaporBlock® Plus™ and the slab, additional care should be given if
sharp crushed rock is used. Washed rock will provide less chance of
damage during placement. Care must be taken to protect blotter layer
from precipitation before concrete is placed.

MADE IN THE USA
SOIL GAS COLLECTOR MAT FOR RADON READY NEW CONSTRUCTION
According to the US EPA’s model stan-dards for radon control systesm 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 ened 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.
WHY & HOW IT WORKS
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 teh filter fabric and into the airspace. The airspace does not clog because the filter fabric retains teh 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. 2

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.radonmat.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 hte 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.
4
7. All openings in the fabric at joints, tee’s, and ends of branches should be
taped to keep out concrete.
8. Stub up a few feet of 4” schedule 40 PVC* from all T risers before pour (or
cover T riser with duct tape). Seal with polyurethene caulk and screws. This
ensures no concrete aggregate enters the riser during slab pour. Be sure to
label “CAUTION RADON REDUCTION SYSTEM” on all pipe. *(6” PVC may be
substituted--for large multifamily projects. Simply cut T riser 4” insert away to
reveal 6” insert).
9. When the building is ready for the vent pipe to be installed above the slab,
fit to pre-stubbed PVC with PVC straight connect. If PVC was not preset, cut
duct tape from riser and insert 4” PVC pipe now. Seal with polyurethene caulk
and secure with screws. Always label “CAUTION RADON REDUCTION SYSTEM”
to avoid confusion on site and for the building occupants.
note: The openings in the riser are laid out at 180 degrees to accomodate
straight runs of mat. However, if the riser is to be placed in a corner, which is
not uncommon, the front of the T can be cut and the SGC mat inserted into
the new opening. The side of the T that is unused should be sealed with tape.
This creates a 90 degree T which will allow corner placement for the riser. Mat
should always enter the T riser from at least two directions and exhaust to pipe
vertically.
SAFETY DATA & PRODUCT DATA SHEETS AVAILABLE @ www.RADONMAT.com 5
MAKING CORNERS AND SPLICES
The mat should be routed around the inside perimeter of the foundation. This
will require occasional corner junctions. Furthermore, splices will have to be
made to join two lengths of mat together. Corners and splices are very easy to
make, and do not require any special fittings. Cut back the filter fabric to reveal
the core material. In the case of a splice, merely overlap the core by at least
one corrugation, replace the cloth, and tape it. Use two landscape staples to
hold the splice in place. In the case of a corner, peel back geotextile fabric and
slice the core of the two adjoining legs at 45 degree angles which mirror each
other; overlap the edges by one corrugation; return grey geotextile fabric, tape
and staple the corner together.
6
CONNECTING THE MAT TO THE
T RISER
A convenient T-riser with dual entry al-
lows for either end of the loop of mat
to be secured to the riser. Slide the
mat into each end of the riser and tape
the edge to prevent wet concrete from
entering. Cap the riser to ensure no
concrete enters. T Riser caps can be
purchased in leui of duct tape. A pres-
tub of PVC pipe can also serve the same
purpose. See steps 8-9 of the previous

POURING CONCRETE
The filter fabric that comes sewn around the soil gas collector prevents the wet
concrete from entering the mat and reducing its air collection capacity. The
only precaution that needs to be taken is that the fabric is duct taped closed at
seams of splices and corner to sufficiently keep the uncured concrete from en-
tering.
The mat also needs to be secured to the soil with landscape staples to prevent
the concrete from lifting off the soil while it is being applied. Re-enforcing bars
and wire can be laid on top of the mat.
Note: the mat is strong enough (4,300 psf) to withstand concrete workers and
their wheel barrows.

RP265 p/n 23033-1
RP380 p/n 28208 1.0 SYSTEM DESIGN CONSIDERATIONS 1.1 INTRODUCTION The RP Series Radon Fans are intended for use by trained, professional Radon mitigators. The purpose of this instruction is to provide additional guidance for the most effective use of an RP Series Fan. This instruction should be considered as a supplement to EPA standard practices, state and local building codes and state regulations. In the event of a conflict, those codes, practices and regulations take precedence over this instruction. 1.2 ENVIRONMENTALS The RP Series Fans are designed to perform year-round in all but the harshest climates without additional concern for temperature or weather. For installations in an area of severe cold weather, please contact RadonAway for assistance. When not in operation, the fan should be stored in an area where the temperature is never less than 32 degrees F. or more than 100 degrees F. 1.3 ACOUSTICS The RP Series Fan, when installed properly, operates with little or no noticeable noise to the building occupants. The velocity of the outgoing air should be considered in the overall system design. In some cases the "rushing" sound of the outlet air may be disturbing. In these instances, the use of a RadonAway Exhaust Muffler is recommended.
(To ensure quiet operation of ENERGY STAR qualified in-line and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the
installation. For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan). 1.4 GROUND WATER In the event that a temporary high water table results in water at or above slab level, water may be drawn into the riser pipes thus blocking air flow to the RP Series Fan. The lack of cooling air may result in the fan cycling on and off as the internal temperature rises above the thermal cutoff and falls upon shutoff. Should this condition arise, it is recommended that the fan be turned off until the water recedes allowing for return to normal operation. 1.5 SLAB COVERAGE The RP Series Fan can provide coverage up to 2000+ sq. ft. per slab penetration. This will primarily depend on the sub-slab material in any particular installation. In general, the tighter the material, the smaller the area covered per penetration. Appropriate selection of the RP Series Fan best suited for the sub-slab material can improve the slab coverage. The RP140/145/155 are best suited for general purpose use. The RP260 can be used where additional airflow is required and the RP265/380 is best suited for large slab, high airflow applications. Additional suction points can be added as required. It is recommended that a small pit (5 to 10 gallons in size) be created below the slab at each suction hole.

1.6 CONDENSATION & DRAINAGE Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below its dew point. This can occur at points where the system piping goes through unheated space such as an attic, garage or outside. The system design must provide a means for water to drain back to a slab hole to remove the condensation. The RP Series Fan MUST be mounted vertically plumb and level, with the outlet pointing up for proper drainage through the fan. Avoid mounting the fan in any orientation that will allow water to accumulate inside the fan housing. The RP Series Fans are NOT suitable for underground burial. For RP Series Fan piping, the following table provides the minimum recommended pipe diameter and pitch under several system conditions.
Pipe
Dia. Minimum Rise per Ft of Run*
@25 CFM @50 CFM @100 CFM @200 CFM @300 CFM
6" - 3/16 1/4 3/8 3/4
4" 1/8 1/4 3/8 2 3/8 -
3" 1/4 3/8 1 1/2 - -
*Typical RP1xx/2xx Series Fan operational flow rate is 25 - 90 CFM 0n 3” and 4” pipe.
(For more precision, determine flow rate by measuring Static Pressure, in WC, and
correlate pressure to flow in the performance chart in the addendum.)
Under some circumstances in an outdoor installation a condensate bypass should be installed in the outlet ducting as shown. This may be particularly true in cold climate installations which require long lengths of outlet ducting or where the outlet ducting is likely to produce large amounts of condensation because of high soil moisture or outlet duct material. Schedule 20 piping and other thin-walled plastic ducting and Aluminum downspout will normally produce much more condensation than Schedule 40 piping. The bypass is constructed with a 45 degree Wye fitting at the bottom of the outlet stack. The bottom of the Wye is capped and fitted with a tube that connects to the inlet piping or other drain. The condensation produced in the outlet stack is collected in the Wye fitting and drained through the bypass tube. The bypass tubing may be insulated to prevent freezing. 1.7 "SYSTEM ON" INDICATOR A properly designed system should incorporate a "System On" Indicator for affirmation of system operation. A manometer, such as a U-Tube, or a vacuum alarm is recommended for this purpose.

1.8 ELECTRICAL WIRING The RP Series Fans operate on standard 120V 60 Hz. AC. All wiring must be performed in accordance with the National Fire Protection Association’s (NFPA)”National Electrical Code, Standard #70”-current edition for all commercial and industrial work, and state and local building codes. All wiring must be performed by a qualified and licensed electrician. Outdoor installations require the use of a U.L. listed watertight conduit. Ensure that all exterior electrical boxes are outdoor rated and properly sealed to prevent water penetration into the box. A means, such as a weep hole, is recommended to drain the box. 1.9 SPEED CONTROLS The RP Series Fans are rated for use with electronic speed controls, however, they are generally not recommended. If used, the recommended speed control is Pass & Seymour Solid State Speed Control Cat. No. 94601-I. 2.0 INSTALLATION The RP Series Fan can be mounted indoors or outdoors. (It is suggested that EPA recommendations be followed in choosing the fan location.) The RP Series Fan may be mounted directly on the system piping or fastened to a supporting structure by means of optional mounting bracket.

2.1 MOUNTING Mount the RP Series Fan vertically with outlet up. Insure the unit is plumb and level. When mounting directly on the system piping assure that the fan does not contact any building surface to avoid vibration noise. 2.2 MOUNTING BRACKET (optional) The RP Series Fan may be optionally secured with the RadonAway P/N 25007-2 (25033 for RP385) mounting bracket. Foam or rubber grommets may also be used between the bracket and mounting surface for vibration isolation. 2.3 SYSTEM PIPING Complete piping run, using flexible couplings as means of disconnect for servicing the unit and vibration isolation. 2.4 ELECTRICAL CONNECTION Connect wiring with wire nuts provided, observing proper connections (See Section 1.8):

Green Ground
Black AC Hot
White AC Common
2.5 VENT MUFFLER (optional) Install the muffler assembly in the selected location in the outlet ducting. Solvent weld all connections. The muffler is normally installed at the end of the vent pipe. 2.6 OPERATION CHECKS _____ Verify all connections are tight and leak-free. _____ Insure the RP Series Fan and all ducting is secure and vibration-free. _____ Verify system vacuum pressure with manometer. Insure vacuum pressure is less than maximum recommended operating pressure (Based on sea-level operation, at higher altitudes reduce by about 4% per 1000 Feet.) (Further reduce Maximum Operating Pressure by 10% for High Temperature environments)
See Product Specifications. If this is exceeded, increase the number of suction points. _____ Verify Radon levels by testing to EPA protocol.
