1.0 Introduction
Hart & Hickman, PC (H&H) has prepared this Vapor Intrusion Mitigation Plan (VIMP) for
installation of a vapor intrusion mitigation system (VIMS) for the proposed multi -story high -
density luxury residential apartment complex on the Bookers Garage Brownfields Property
(Brownfields Project No. 23074-19-060) located west of the intersection of Seigle Avenue and E.
15th Street in Charlotte, Mecklenburg County, North Carolina (Site). The Site is identified as 1113-
1121 Seigle Avenue and 820 E. 15th Street. Redevelopment plans for Site include a high -density
luxury residential apartment complex with a sub -grade parking garage. A Site Map is included as
Figure 1, and a redevelopment plan depicting the proposed residential building and parking garage
is included as Attachment 1.
Between November 2019 and November 2020, ECS Southeast, LLP (ECS) completed soil,
groundwater, and soil gas assessment activities within the footprint of the proposed building to
evaluate subsurface conditions for potential impacts. In addition, soil samples were taken along
the historical and current building footprints to identify the potential for lead impacts from
residential building drip -lines. Summary tables and figures depicting the analytical results and
sample locations are included as Attachment 2. Results of the soil and groundwater assessment
activities did not identify any volatile organic compounds (VOCs) in soil or groundwater at
concentrations above laboratory reporting limits. Furthermore, the groundwater assessment results
did not identify any compound concentrations above the North Carolina Department of
Environmental Quality (DEQ) 2L Groundwater Quality Standards (2L Standards). The results of
soil gas assessment activities indicated detectable concentrations of VOCs in soil gas. The
detected concentrations were below DEQ DWM Vapor Intrusion Sub -slab and Exterior Soil Gas
Screening Levels (SGSLs) for residential use, with the exception of trichloroethene (TCE) in two
soil gas samples. TCE was detected above the Residential SGSL of 14 µg/m3 in SG-2 in August
2020 (31.8 µg/m3) and in SG-3 in November 2020 (46 µg/m3). TCE was not detected above the

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

Residential SGSL in other soil gas samples collected at the Site. Sample locations and results of
historical assessment activities are included in Attachment 2.
To further evaluate the potential for structural vapor intrusion into the proposed residential
building, ECS utilized the DEQ Risk Calculator to evaluate potential cumulative vapor intrusion
risks under a residential use scenario. Using the detected concentrations at each soil gas sample,
for each separate event, results of the DEQ vapor intrusion risk calculations indicate that the Site -
specific risks at each soil gas sample location do not exceed the DEQ or EPA risk thresholds.
The Brownfields Agreement for the Site is expected to include the following standard land use
restriction associated with vapor intrusion:
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.
Although soil gas and groundwater analytical data for the Site do not indicate a vapor intrusion
risk, out of an abundance of caution and in compliance with the Brownfields Agreement land use
restriction above, the PD has decided to install a VIMS as part of the residential building
construction activities. Therefore, this VIMP has been prepared for installation of a passive VIMS
during construction of the proposed residential building.
The VIMP is described in the following sections and was designed in accordance with the DEQ
DWM Vapor Intrusion Guidance (VI Guidance) dated March 2018, the DEQ Brownfields
Program Preliminary Vapor Intrusion Mitigation System Design Submittal New Construction
Minimum Requirements Checklist included as Appendix H of the VI Guidance document, and
using design information provided in the Interstate Technology Regulatory Council Vapor

2.0 Design Basis
The VIMP is included in Attachment 3 (Sheets VM-1 through VM-3) and will be used to guide
construction of the VIMS. The proposed Site redevelopment plan includes a sub -grade parking
garage with three levels of luxury multi -family residential use above. The northwestern residential
units are located over the one -level parking garage, and the four first -level residential units along
Seigle Avenue are slab -on -grade. The proposed building areas above the parking garage and on
grade are shown in Figure 1.
• The proposed building footprint above the parking garage is approximately 7,140 square
feet and includes residential units and the lobby area.
• The proposed slab -on -grade units located along Seigle Avenue total approximately 2,815
square feet and consist of two unit blocks which are connected at the open-air lobby area.
Please note, the residential units located on the eastern corner of the property do not sit
fully on grade as the western edges are located over the parking garage.
Based on the location of the parking garage under the residential units and lobby area in the western
part of the Site, a VIMS is not proposed for this portion of the redevelopment. As outlined in the
Building Design Tech Sheet on the Interstate Technology Regulatory Council:
According to international and domestic building codes, vented garages, or
enclosed parking structures using enhanced building construction for
natural ventilation and/or mechanical ventilation techniques associated with
vehicle exhaust mitigation, as shown in Figure 1, are required to meet certain
minimum air exchange rates (AERs). These are intended to limit exposure to
carbon monoxide (CO), nitrogen dioxide (NO2), volatile organic
compounds (VOC), and particles from the automobile exhaust within the enclosed
parking garages and within occupiable spaces that are connected (both adjacent
and above). When vented garages are constructed below occupied spaces that are
intended for living or working, these structures may provide mitigation of VI from
subsurface sources because of the high AER required by code.

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

The parking garage is approximately 50% open-air (mechanical ventilation is not planned) with
openings along the northwest and southwest walls as well as the open-air entrance ramp. There is
a recycling room in the garage that appears to be enclosed and one stairwell near the southern
corner of the garage that is enclosed with CMU fire walls on the garage and first -floor levels. The
stairwell does not open into enclosed, occupiable space. The proposed VIMP discussed below is
for the four proposed slab -on -grade residential units located along Seigle Avenue. As a
conservative measure, vapor barrier was included beneath the recycling room and the enclosed
garage stairwell. The VIMS does not extend under the remainder of the open-air parking garage,
open-air stairwells, or elevator. There are no known utility connections from the parking garage
into the residential spaces, and the elevator is not connected to enclosed occupiable space. On
each residential level, the exterior stairwells and elevators connect to open-air space.
The VIMP includes installation of VaporBlock® Plus 20 (VBP20) vapor barrier manufactured by
Raven Industries (Raven) beneath the ground level concrete slab of each of the four proposed slab -
on -grade residential units. VBP20 is an ASTM-certified 20-mil, multi -layer, chemically resistant
vapor barrier, designed to prevent the migration of volatile organic compounds (VOCs). Technical
specifications and installation instructions obtained from Raven for the VBP20 vapor barrier are
provided in Attachment 4.
The VIMP specifies that the vapor barrier will be installed per manufacturer installation
instructions (Attachment 4). Briefly, VBP20 will be installed by the construction contractor to
cover the ground surface below the entire area of the four proposed slab -on -grade ground floor
residential units. The exterior edges of the VBP20 will be attached and sealed to existing concrete
utilizing VaporSealTM tape or Butyl Seal double -sided tape. Seams within the building footprint
will have a minimum 12-inch overlap and will be sealed with VaporSealTM tape with the option of
supplementing the seal with double -sided Butyl Seal tape. Small puncture holes will be sealed
with VaporSealTM tape or Pour-N-Sea1TM, 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 practical or
hart hickman

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

deemed as "ineffective" by the VIMS design engineer (design engineer), the Pour-N-Sea1TM
method will be used to form an airtight seal around the penetrations.
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 design 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 design engineer which meets the criteria specified in Sheet VM-1 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. In the event that
an alternate equivalent vapor barrier liner (other than VBP20 or Drago Wrap®) is selected, DEQ
approval will be requested in writing prior to installation.
The VIMP also includes installation of a passive mitigation system beneath the slab -on -grade
ground level slabs of the eastern residential units to reduce the potential for vapor intrusion into
the proposed buildings by vapor extraction. The passive mitigation system consists of vapor
collection/conveyance piping which will collect vapor from beneath the ground floor slab of the
building and discharge the vapor through exhaust stacks installed above the building roof. Empire
Model SV04SS (stainless steel) Syphon Ventilators (or a design -engineer approved alternate) will
be 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. Empire Syphon Ventilator and slotted PVC piping product
specifications are included in Attachment 4.
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 slab to
allow for air movement beneath the entirety of the slab. Sub -slab vapor collection piping (3-inch
diameter) will be 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 and a minimum of 1
inch below the sub -slab piping (for example, 5 inches of gravel around a 3-inch pipe). In areas
without sub -slab piping, a minimum thickness of 4 inches of clean stone is required.

In the event the system needs to be activated with electric fans (see Section 4.0), the VIMP includes
permanent vacuum measuring points (depicted in Sheet VM-3). The vacuum measuring points
will be used to measure the pressure differential between indoor air and the sub -slab, should
electric fans be needed. Sub -slab soil gas samples will also be collected from the vacuum
measuring points. To prevent disrupting occupants in the future, the vacuum measuring point
access ports are located on the exterior walls (see Sheets VM-2 and VM-3 in Attachment 3).

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:
• after installation of horizontal collection system and gravel base placement;
• after vapor barrier installation and prior to pouring the concrete building slab; and
• after installation of vertical exhaust riser pipe and ventilator installations.
Please note that a fourth inspection will be conducted if the VIMS is activated and electric fans
are installed, 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. The locations of areas with multiple penetrations
where Pour-N-Sea1TM is used will be photographed and noted on the field logs. The use of hollow
piping by contractors to support their utilities in preparation for concrete pours is not permitted
and will specifically be observed and removed as needed during the inspections. As requested,
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 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,
unless the influence test reveals that modifications are needed to the VIMS to achieve the required
vacuum influence of 4 pascals (0.016-inches water column). In this case, the test results will be
used to facilitate VIMS repairs or modifications which will be included in the construction
completion report.
Sub -Slab Gas Sampling
Sub -slab soil gas sampling will be performed to document system efficacy and determine if indoor
air sampling is warranted. An initial pre -occupancy sub -slab soil gas sampling event will be
conducted upon completion of successful influence testing and a minimum of two weeks following
installation of the syphon ventilators on the roof. Subsequent post -occupancy sub -slab vapor
sampling will be performed approximately 6 months after the initial pre -occupancy sampling event
and then on a semi-annual basis for future events. If semi-annual sampling results indicate
consistent or decreasing concentrations within acceptable risk levels, a request to modify or
terminate sampling will be submitted for DEQ approval. No changes to the sampling frequency
will be implemented until written approval is obtained from DEQ..
During each sampling event, sub -slab soil gas samples will be collected from each permanent
vacuum measuring point, for a total of three samples per event. Based on the VIMS design, which

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

consists of three distinct passive extraction systems, the sample locations (as shown on VM-3)
have been selected to represent conditions within each individual passive sub -slab venting system.
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
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 and further
discussed below.
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. 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 Summa canisters at an approximate flow rate of
100 mUmin. 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.
Although, the DWM VI Guidance recommends initial groundwater and soil gas assessment
activities be completed to reduce the analyte list for future vapor intrusion assessments and aid in
eliminating background sources, DEQ requires the sub -slab samples be analyzed for the full list

of VOCs. As such, H&H will submit the sub -slab soil gas samples for analysis of the full list of
volatile organic compounds by EPA Method TO-] 5.
The samples will be submitted to a qualified laboratory under standard chain of custody protocols
for analysis of VOCs by EPA Method TO-15. The laboratory will be instructed to report J-flag
concentrations for each sample and to report received canister vacuum. 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 Sub -Slab and Exterior Soil Gas
Screening Levels (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
scenario. In the case where calculated cumulative risks are less than 1x104 for potential
carcinogenic risks and below a hazard index of 1 for potential non -carcinogenic risks, the system
will be considered effective. If risk calculations remain within acceptable risk levels for multiple
sub -slab vapor sampling events, a request to modify the sampling frequency or terminate sampling
will be submitted for DEQ approval. No changes to the sampling frequency will be implemented
until written approval is obtained from DEQ.
In the event that calculated cumulative risks are greater than 1x104 for potential carcinogenic risks
and/or above a hazard index of 1 for potential non -carcinogenic risks for either the pre- or post -
occupancy sampling events, indoor air sampling will be completed, as described below. 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 cumulative risks.
If background sources are identified and confirmed, DEQ will be notified and indoor air sampling
will not be performed, if DEQ concurs in writing.
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, if warranted) are submitted to DEQ and written
approval for occupancy is obtained from DEQ.

Indoor Air Sampling (if warranted)
The need for indoor air sampling will be determined based on the results of each sub -slab vapor
sampling event, as indicated above. The buildings are intended to be occupied shortly following
completion and initialization of the HVAC system. If the pre -occupancy sub -slab vapor sampling
results indicate that pre -occupancy indoor air sampling is warranted, the sampling will be
conducted following construction and completion of the VIMS and after the syphon ventilators
have operated for a minimum of two weeks. If indoor air sampling is required, the locations and
number of indoor air samples will be chosen based on the sub -slab sampling analytical data and
discussions between H&H and DEQ. The building shall not be occupied until the indoor air results
are provided to DEQ and written approval for occupancy is obtained from DEQ.
Each indoor air sample will be collected in accordance with the DWM VI Guidance, using a 6-
liter Summa canister over a 24-hour period. The samples will be 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 for each building and per discussion
between H&H and DEQ. Each indoor air Summa canister will be connected to a dedicated 3-ft
sampling cane which will place the indoor air sample intake at a height consistent with the
breathing zone when the sample canister is set on its base.
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 IASLs. Per standard procedure, the laboratory will report the vacuum levels

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

of the canisters upon receipt by the laboratory. 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.
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
1x10-4 for carcinogenic risks or below a hazard index of 1 for non -carcinogenic risks. Prior to
completing additional indoor air sampling, an evaluation of potential background sources will be

SMARTER FMlIPoONMEF1TAx SOLIJTIOkS

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(s) will first be
evaluated to increase effectiveness. 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).
The results of any indoor air sampling completed at the Site will be reported to DEQ, as indicated
in Section 7.0.

5.0 Post -Occupancy Testing
The VIMS is proposed as a passive system which will utilize sub -slab vapor extraction through
vapor extraction piping and syphon ventilators. 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 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 DEQ Brownfields Program for approval prior to
implementation. Specifications for the fan to be used if conversion to the active system is deemed
necessary are included in Attachment 4.
As discussed above, post -occupancy sub -slab soil gas sampling will be completed post -
construction on a semi-annual basis. The sub -slab sampling will be completed using the methods
discussed above. If semi-annual sampling results indicate consistent or decreasing concentrations
within acceptable risk levels, a request to modify or terminate sampling will be submitted for DEQ
approval. No changes to the sampling frequency or termination of sampling will be implemented
until written approval is obtained from DEQ.

6.0 Future Tenants & Building Uses
The future use of the proposed Site buildings includes multi -family residential use. After
occupancy of the Site buildings, 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 PE to
oversee or inspect the activities, and a report will 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.

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 will include a
summary of VIMS installation activities, quality assurance and quality control measures, pre-
occupancy system effectiveness testing including sub -slab and/or indoor air assessment results,
inspection photographs, SDSs, as -built construction drawings, and an opinion as to whether the
VIMS was installed in accordance with the DEQ-approved VIMP. Multiple reports may be
submitted depending on the construction schedule of the residential development.
Prior to occupancy of the building, the results of the influence testing, sub -slab vapor sampling,
and indoor air sampling (if completed) will be submitted to the Brownfields Program. The building
shall not be occupied until DEQ provides written approval.
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.

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.
Ri111111039
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.

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 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 VaporSealT" 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.
VaporSeaTMT°" Tape (option) - Tape completely around pipe
overlapping the VaporBlock® Plus- square to create a tight seal
against the pipe.
F) Complete the process by taping over the boot perimeter edge with
VaporSeal- Tape to create a monolithic membrane between the
surface of the slab and gas/moisture sources below and at the slab
perimeter. (Fig. 4 & 6)

1.5. Sealing side -by -side multiple penetrations (option 1);
A) Cut a patch large enough to overlap 12" in all directions (Fig. 7)
of penetrations.
B) Mark where to cut openings and cut four to eight slices about
3/8" less than the diameter of the penetration for each.
C) Force patch material over penetration to achieve a tight fit and
form a lip.
D) Once patch is positioned, seal the perimeter to the membrane
by applying 2-sided Raven Butyl Seal Tape in-between the two
layers. (Fig. 8)
E) After applying Raven Butyl Seal Tape between the patch and
membrane, tape around each of the penetrations and the patch
with VaporSeal'" 4" tape. (Fig. 9) For additional protection apply
POUR-N-SEAL'" or an acceptable polyurethane elastomeric
sealant around the penetrations. (Fig. 10)

Option 2
1.6. POUR-N-SEALT" 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-
SEALT" 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-SEALT" in plastic container for longer
than the time it takes to pour sealant.
Fig. 12
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® 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" 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® PIUSTM. 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® PIusTm 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.

The Empire Syphon Ventilator is a
dependable stationary exhauster
that functions efficiently in the
slightest breeze. Its design utilizes
every wind current to create a pow-
erful suction through the stack, while
the storm band circling the upper
cone prevents rain from driving into
the ventilator and adds to its exhaust
The Eveco Ventilator is a single cone
vent, ideal for low cost ventilation.
Though the cost of this unit is slight,
it provides maximum ventilation in all
types of weather.

1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
RP140 p/n 23029-1
RP145 p/n 23030-1
RP260 p/n 23032-1
RP265 p/n 23033-1

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 GROUNDWATER
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.
IN020 Rev K Page 3 of 8

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.

*Typical RP1xx/2xx Series Fan operational flow rate is 25 - 90 CFM On 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.)
CC
Under some circumstances in an outdoor installation Byr
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 incor orate a
"System On" Indicator for affirmation off system
operation. A manometer, such as a U-Tube, or a
vacuum alarm is recommended for this purpose.
RISE
RUN
IN020 Rev K Page 4 of 8

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.
IN020 Rev K Page 5 of 8

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):
Fan Wire
Connection

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.
