The planned use of the Site is for construction of a 5-story, 391-unit multi-family residential
complex, which will include a residential building, parking garage, elevators, ancillary courtyard
structure, swimming pool, dog park, and other amenities. The ground floor/slab on grade
footprint of the residential building will be approximately 119,879 square feet (SF). The ground
floor/slab on grade footprint of the parking garage will be approximately 31,152 SF. A layout of
the planned structure is provided in Drawing TTL while Figure 2 depicts the layout of the
planned structure relative to previous environmental assessment sample locations.

1.1 Site History

The Site and its existing structures are currently occupied by Hal Abernethy Contracting, a
demolition and site contractor, who purchased and occupied the Site in 2001. The Site includes
an approximate 10,932-SF industrial structure with silo built in 1962 along with an open-sided
canopy storage structure formerly associated with a cement manufacturing facility. Based on
historical information, from at least 1905 to around 1950, the Site included several dwelling-size
structures on southern and central portions of the Site. From 1951 to about 1965, the Site
included warehouse-size structures on the northern portion of the Site. Since 1965, the existing
large structure appears on the west-central portion of the Site along with what appears to be
several storage structures or transport trailers on the central and northern portions of the Site.
From around 1965 through 1974, the property was reportedly occupied by Marquette Cement
Manufacturing Co., and after 1974 by Tarmac Virginia, a limestone distributor. All existing Site
structures and infrastructure will be razed as part of Site redevelopment.

1.2 Previous Environmental Assessments

The following environmental assessment reports have previously been submitted to NCDEQ by
ESP or others that address environmental conditions at the Site including:
• “Passive Soil Gas and Surface Water Investigation - Southern Resources Scrap Metal”
dated October 25, 2021, by ATC Associates of North Carolina, P.C. (ATC);
• “Report of Phase I Environmental Site Assessment - Proposed Abernethy Lofts
Residential Development Site” dated June 29, 2022, by ESP;
• “Report of Phase II Environmental Assessment - Proposed Abernethy Lofts Residential
Development Site” dated August 1, 2022, by ESP;
• “Report of Supplemental Phase II Environmental Assessment - Proposed Abernethy
Lofts Residential Development Site” dated February 9, 2023, by ESP; and
• “Receptor Survey Letter - Tarmac Virginia Brownfields Property” dated May 30, 2023.

Previous assessment results associated with the above reports are summarized on Tables 1
through 9 while associated maps are provided as Figures 1 through 8.

As noted on Table 6, the only analytes detected above their corresponding NC 2L standards in
groundwater at the Site were tetrachloroethene (PCE) and trichloroethylene (TCE), each in only
1 of the 12 groundwater samples collected. PCE at a concentration of 0.82 J µg/L in monitoring
well TMW-1 exceeded its NC 2L standard of 0.7 µg/L. TCE at a concentration of 5.4 µg/L in
monitoring well TMW-5 exceeded its NC 2L standard of 3 µg/L. The only analyte detected in
groundwater at the Site that exceeded its residential groundwater vapor intrusion screening
level (VISL) is TCE in monitoring well TMW-3 at a concentration of 5.4 µg/L compared to the
residential groundwater VISL for TCE of 1 µg/L.

As noted on Table 8, results of analysis of soil gas samples from nine temporary soil gas probes
(SVP-1 through SVP-9) found that the only volatile organic compound (VOC) detected above its
residential soil gas (SG) VISL was TCE. TCE exceeded its residential SG VISL of 14 µg/m3 in 2
of the 9 soil gas samples: 17.9 µg/m3 in SVP-3; and 46.5 µg/m3 in SVP-7.

Sub-slab soil gas sample analytical results from five sub-slab soil gas probes (SSVP-1 through
SSVP-5) revealed that no sub-slab soil gas sample result exceeded its corresponding
residential SG VISL (see Table 8).

1.3 VIMS Design Overview

To mitigate potential vapor intrusion (VI) risks to future Site residential occupants, the passive
vapor intrusion mitigation system (VIMS) detailed herein was designed for planned residential
structure. The design of the VIMS was configured to account for potential VI risk across the entire
residential structure (excluding the parking garage); however, as noted in the above referenced
reporting, TCE was the only analyte detected in collected soil gas samples that exceeded its
residential SG VISL (see Figure 8). TCE exceeded its residential SG VISL of 14 µg/m3 in 2 of
the 9 soil gas samples: 17.9 µg/m3 in SVP-3; and 46.5 µg/m3 in SVP-7. Additionally, it should
be noted that no sub-slab soil gas sample analytical results (SSVP-1 through SSVP-5) exceeded
their corresponding residential SG VISLs (see Figure 9).

The passive VIMS on the Site will consist of a sub-slab vapor barrier system along with an
underlying low-profile vapor mat connected to thirty (30) vertical vent risers. The vapor mat will
collect possible vapors from beneath the concrete slab and discharge the vapors through the
vertical riser vents above the building roofline. The construction of the open-air parking garage
includes ventilation per county code requirements, as such, only the ground floor portions of the
parking garage that contain enclosed rooms will include VIMS components, as detailed in
subsequent sections of this plan and drawings. The parking garage structure has its own
ventilation system which is capable of handling air movement within these public spaces. The
mechanical drawing set showing the proposed ventilation system for the parking garage is
presented as Appendix E.

2.0 DESIGN BASIS

2.1 VIMS Design

This VIMS plan documents the design, planned installation and quality assurance/quality control
(QA/QC) program, post-construction/pre-occupancy testing, and post-occupancy effectiveness
testing for the VIMS. Elements of the passive VIMS design include the following:
• Preparatory tasks
• VIMS installation
• Vent riser and sub-slab vapor pin monitoring locations
• Roof top ducting
• Sealing and testing requirements
• Drawings identifying the location and layout of the vapor barrier, sub-slab
venting system, and typical cross sections of the vapor barrier and tie-ins
to major foundation structural components;
• Specification details for VIMS installation procedures;
• QA/QC oversight procedures;
• Post-construction/pre-occupancy testing;
• Post-occupancy effectiveness testing; and
• Reporting.

This document was prepared as a summary narrative of the VIMS elements. Attached to this
summary document are KU Resources’ design specifications for the vent system layout,
installation instructions, manufacturer literature detailing the Cetco VI-20 barrier product, Liquid
Boot spray at seams and penetrations, and supplemental information regarding VIMS system
components. Note that all drawings provided in this specification are for regulatory use and
approval only. The information used to prepare these drawings was obtained from Site design
drawings prepared by others. Please refer to the appropriate structural, foundation, and MEP
drawings for construction-related details for the VIMS installation.

KU Resources, Inc. has prepared this VIMS design to incorporate current industry standards that
will be acceptable to the North Carolina Brownfields Program (NCBP) to protect future occupants
and workers from potential VI exposure. The VIMS installation is to occur during construction
activities involving the slab foundations. The VIMS design provides conservatism and redundancy
to effectively mitigate the VI exposure pathway, while providing flexibility for potential changes that
could occur over the life of the building.

The proposed passive VIMS will generally include the following, as detailed in the attached
specifications:
• Installation of a gas-permeable layer consisting of gravel (#57 stone or equivalent). The
gravel base layer will be a minimum of 4” thick.

• Installation of a passive sub-slab venting system, comprised of the following:
o Horizontal runs of sub-slab low-profile vapor mat vent system laid out overlying
the gravel base layer (see Drawing V101-1 for the vapor mat layout and Drawing
V102-1 for section details and specifications in Appendix A).
o The low-profile vapor mat vent system is designed to convey vapor across
concrete footers that would otherwise be a barrier to fluid transport. The sub-
slab vent system connects to the vertical vent risers through the use of a CETCO
End Outlet with Reducer (see Drawing V101-1 for the riser locations and Drawing
V102-1 for section details).
o The horizontal vent system will be connected to a total of thirty 4-inch diameter

solid Schedule 40 PVC vertical risers throughout the mitigation area. Each
vertical riser is estimated to have a capacity to accommodate sub-slab
depressurization of up to 2,000 SF of sub-slab area (see Drawing V101-1).
o The vent risers will extend through the height of the building (approximately 55
feet) and will be exhausted a minimum of 1 foot above the roof and at least
10 feet from any openings or air intakes (e.g., windows, HVAC intakes, etc.).

• Installation of an impermeable vapor barrier system consisting of Cetco VI-20
geomembrane (20 mil) which is a multi-layered polyethylene and ethylene vinyl alcohol
(EVOH) copolymer geomembrane barrier. All seams and penetrations will be sealed
with a 60-mil spray application of Liquid Boot Compound A. A layer of Cetco Ultrashield
G-800 geotextile will be installed over the vapor barrier as a cushioning barrier to protect
the vapor barrier from punctures prior to and during the concrete slab pours (see
Drawings V102-1, V102-2, and V102-3 for details).

• The VIMS is designed to function as a passive system. If post-construction
effectiveness testing indicates the system must be converted to an active system, fans
will be installed on each of the 30 vertical vent stacks above roof level or in attic crawl
spaces. If fans are required, the fans are sized to provide a minimum vacuum of 4
pascals (0.016 inches of water column). This level of sub-slab depressurization will meet
NCBP minimum requirements (4 pascals).

The specifications for the CETCO Geovent Gas Venting System, Cetco VI-20 vapor barrier,
Liquid Boot Compound A, Cetco Ultrashield G-800, Watchdog H3 membrane, RadonAway fans
(if required), and their general installation methods are included in Appendices A through D of this
report. The Liquid Boot Plus VI-20 component specifications in Appendix B are the latest available
according to the manufacturer. Should the manufacturer provide updated specifications at the time
of product purchase, the specifications provided in Appendix B will be superseded by the more
recent version of the specifications. Also included in Drawings V102-1, V102-2, and V102-3 are
vendor specifications and drawings showing the configuration and details of the barrier and vent
installation methods in and around penetrations, footings, terminations and other features of the
building’s foundation and footprint. Drawing V102-3 also provides a detail of the VI-20 barrier
system and Watchdog H3 membrane installation for the elevator shafts.

The passive venting system and vapor barrier will be installed across the entire footprint of the
residential building (excluding the parking garage) beneath the concrete floor slab
(approximately 119,879 SF - see Drawings TTL and V101-1 through V102-3).

The underlying low-profile vapor mat will be connected to a total of 30 vertical vent risers
constructed of solid 4-inch diameter Schedule 40 polyvinyl chloride (PVC) pipe. The vertical
vent risers extend from the sub-slab to the roof of the building (as noted in Drawings V101-1
through V101-5 and V101-R). Vent riser pipes, no greater than every 10 feet where visible and
accessible in utility closets or wall cavities, will be clearly labeled. The pipe labels will indicate
that the piping is associated with a vapor barrier and venting system (e.g., Soil Vent Pipe); and
will provide the name, address, and telephone number of the entity to contact for
questions/repairs. The VIMS also has the capability to mitigate potential moisture and radon
concerns, which is outside of the Brownfield Redevelopment Section’s purview.

If post-construction testing indicates the venting system must be converted from a passive
system to an active system, all 30 of the vent risers could be fitted at the roof termination with
in-line RadonAway® RP Series RP265 fans for active depressurization of the sub-slab. This will
require 120-volt, 20-amp electrical service connections in the vicinity of each vent riser at the
Vapor Intrusion Mitigation System Plan ESP Project No. E6-KO31.600
Tarmac Virginia Brownfields Property - Brownfields Project No. 26067-22-060 November 14, 2023

roof locations to accommodate the optional fan units. One fan will be installed for each vertical
riser pipe for a total of 30 fans. If fans are required, each vent riser would be equipped with a
visual alarm that will light if the associated fan shuts down. These individual visual fan alarms
will be located on the ceiling of the upper floor of the building and closest to their associated
vent stack/fans.

2.2 Parking Garage Design

The parking garage, which mostly separates the northern and southern sections of the residential
structure, will not be constructed with a VIMS, with the exception of enclosed rooms on the ground
floor of the parking garage. The parking garage will be open to the atmosphere and have its own
independent interior ventilation system per applicable county code requirements (see Drawings in
Appendix E). The garage ventilation system is served by three (3) fans located at the roof level
on the garage exhaust shaft, two type GEF-A and one type GEF-B. The GEF-A’s are controlled
by a CO/NO2 detection system, and the GEF-B will run continuously to meet the minimum
building code requirements for continuous ventilation. One System Control Panel shall be
located on each parking level requiring ventilation. CO/NO2 sensors are located to cover
approximately 5,000 SF each on each floor of the garage. Upon detection of CO/NO2 levels
exceeding the setpoints, the sensors will send a signal to the control panels which will energize
the GEF-A’s to run at full capacity until CO/NO2 levels fall below the setpoints, at which point
the sensors and fans will reset to normal operation. Openings to outdoor air are provided on the
south end of the parking deck at each level to allow for make-up air. Louvers are provided at the
ventilation shaft at each level, sized for the required ventilation for each level.

The Parking deck is approximately 31,152 SF at ground level. The total parking garage (all
floors combined is approximately 193,268 SF; however, 5th floor level is completely open to
outdoor conditions. Floors 1 through 4 of the garage require a minimum of 5,886 cubic feet per
minute (CFM) of continuous ventilation, and 88,293 CFM of ventilation should the CO/NO2
sensors be triggered. The GEF-B will provide 6,500 CFM of continuous ventilation. Each of
the two GEF-A fans will provide 47,500 CFM of intermittent ventilation for a total of 95,000 CFM.

While the parking garage is not considered occupied space, implementation of the ventilation
system will be fully protective of public health from vapor intrusion concerns.

3.0 QUALITY ASSURANCE/QUALITY CONTROL

As part of the quality assurance/quality control (QA/QC) process, inspections during each phase
of the VIMS installation will be performed by qualified personnel under the supervision of the
design PE and will include field logs and photographs. These inspections will be performed for
all gravel and piping prior to installing the vapor barrier, and for all sections of the vapor barrier
and smoke testing prior to pouring slabs. A minimum of 2 business days’ advance notification
to NCBP prior to inspections will be provided.

A representative under the supervision of design PE will conduct Site visits to inspect and verify
that the barrier materials meet criteria, and that the barrier system has been installed in general
accordance with the VIMS design and manufacturer’s specifications. This will include
confirmation prior to covering the gravel and piping, and confirmation that construction activities
and Site improvements have not created punctures to the barrier system during the installation
of wire mesh, rebar, post-tension tendons, etc., prior to the concrete floor slab pours. Site visits
will be documented using field forms and photographs, which will be submitted to the NCBP as
an appendix in the VIMS as-built deliverable.

Each VIMS component will be inspected by qualified personnel under the supervision of the
design PE, prior to being covered. The inspections will include field logs and photographs of
each section of slab. The installation contractor will be instructed to notify the design PE, with at
least a 2-business day notice prior to planned inspection, with NCBP provided a subsequent
notice of the pending inspection.

The VI-20 barrier system must be installed by a Cetco certified “Approved Applicator” to
maintain product warranty. The installer’s “Approved Applicator” certification from the gas
vapor membrane manufacturer will be included in the as-built deliverable. The firm should be
trained and approved by the manufacturer for the installation and should have at least 3 years of
experience in similar work and be able to comply with the manufacturer’s warranty
requirements. QA measures are necessary to maintain system integrity during construction
activities on the Site. Oversight is to be conducted by qualified personnel under the supervision
of the design PE.

If during the installation of the VIMS, field adjustment or deviations from the approved design
plans must be made to avoid unforeseen conflicts, the deviations must first be pre-approved by
the VIMS design PE, prior to being completed at the Site. NCBP will be notified regarding
significant deviations and whether a VIMS design addendum is required to document the
significant deviation.

Once the VIMS installation is complete, smoke tests of the vapor barrier system will be
performed by the Cetco certified Approved Applicator with an independent third party under the
supervision of the design PE providing oversight. The smoke testing will be completed to
identify potential leaks in the vapor barrier membrane or sealed penetrations. Smoke testing
and/or thickness (coupon) measurements will be performed for both roll-out and spray applied
seams/seals with coupon testing only being performed on spray applied seams. During any
time that the VIMS is left exposed (i.e., without a concrete slab in place), protective measures
will be implemented to prevent damage to the system. If a slab pour over the VIMS is delayed,
the Cetco Ultrashield G-800 non-woven geotextile installed on top of VI-20 vapor barrier will
protect the vapor barrier. Additional protective measures to protect the VIMS will be provided
which may consist of installing temporary wooden boards placed over the area to allow safe
access, and/or barriers, and/or signage restricting access.

Upon completion of installation of the VIMS, a PE designer representative will prepare an as-built
deliverable summarizing the above installation and QA/testing measures. As noted in Section 7.0,
the as-built deliverable will also include photographs and the sealed statement of a NC-licensed
PE that the VIMS has been installed to the satisfaction of such engineer. The as-built deliverable
will be submitted to the NCBP and will include as-built drawings and logs/photographs of
inspections in appendices, and will detail any significant modifications to the VIMS design.

4.0 POST-CONSTRUCTION/PRE-OCCUPANCY EFFECTIVENESS TESTING

Prior to occupancy, pilot/influence testing and one round of post-construction sub-slab vapor and
indoor air quality testing will be performed to test the effectiveness of the Site’s VIMS and
document existing conditions. Results of the pre-occupancy testing will be evaluated in
consultation with the NCBP to determine if the number of proposed post-occupancy sampling as
events (as detailed in Section 5.0) can be reduced.

The pilot/influence testing as well as sub-slab vapor sampling will be performed utilizing the vapor
pins as depicted on Drawing V101-1. Twenty-one (21) vapor pins will be installed, as depicted on
Drawing V101-1. Vapor pins #1 through #15 will be utilized for both effectiveness testing and sub-
slab vapor sampling. Vapor Pins #16 through #21 will be used for initial effectiveness testing.
Indoor air testing will be performed 1 to 3-days prior to sub-slab vapor sampling to avoid influences
to indoor air from sub-slab sampling activities. Indoor air sampling will be completed at ten (10)
locations (IAS-1 through IAS-10, as depicted on Figure 10). The sampling will be performed in
general accordance with the most current version of NCDEQ’s Vapor Intrusion Guidance
document. Sub-slab vapor and indoor air sampling locations will be finalized in consultation with
the NCBP prior to sampling.

It should be noted that pour back areas are not part of planned construction.

4.1 Pilot/Influence Testing

Post-construction/pre-occupancy pilot/influence testing will be performed to evaluate vacuum
communication for individual sections across the slab and confirm sufficient depressurization can
be obtained should active fans be needed in the future. The pilot/influence testing will be
performed following installation of the horizontal sub-slab low-profile vapor mat, placement of the
vapor barrier, and completion of individual concrete slab pours.

For pilot/influence testing, vapor extraction fans will be attached directly to one or more vertical vent
riser pipes for the section of the slab being evaluated. Pressure differential will be measured at
extraction fan locations and sub-slab vacuum levels will be measured at appropriate vapor pin
monitoring point locations. A pressure differential below the slab of at least 4 pascals at remote
distances from vent riser locations in each area will be considered as sufficient evidence of
adequate sub-slab VIMS influence. If lower than 4 pascals are recorded at individual vent riser
locations, these readings will be discussed with NCBP to evaluate whether these readings are
adequate based on other data. Vacuum influence testing results will be included in the VIMS
installation completion report. If the influence testing results indicate that modifications to the VIMS
are needed to achieve sufficient sub-slab depressurization, NCBP will be notified of the
modifications prior to submittal of a VIMS installation completion report as discussed in Section 7.0.

4.2 Sub-Slab Vapor Sampling

To assist with our understanding of sub-slab conditions as they relate to the presence of sub-
slab vapor and indoor air quality conditions, sub-slab vapor samples will be collected from the
fifteen (15) vapor pin monitoring points (Vapor Pins #1 through 15, as depicted on Drawing
V101-1). The vapor pins, to be located either in common areas or within mechanical/electrical
rooms or storage closets, will be installed prior to pouring of the concrete slab. Vapor pin details
are provided as Specification 11 on Drawing V102-2.

The sub-slab vapor samples will be collected during one round of post-construction testing to
Vapor Intrusion Mitigation System Plan ESP Project No. E6-KO31.600

document existing vapor concentrations beneath the building’s slabs and allow comparison of
this data to indoor air testing results. The sub-slab vapor samples will be collected from the
individual vapor pins by connecting a batch-certified 1-liter Summa canister using a T-fitting to
the vapor pin and opening the valve of the Summa canister to allow collection of a gas sample.
Prior to collection of the sub-slab vapor sample, the vapor pin will be evacuated using an air
pump. A shroud will be placed over the sample train and the shroud filled with helium with the
internal helium concentration recorded with a calibrated helium gas detector. The shroud will
encompass the entire sampling train including the Summa canister. Vapor from the vapor pin
inside the shroud will then be pumped into a Tedlar bag to be screened in the field with a helium
detector to identify the possible presence of a leak within the sampling train. If the helium
concentrations within the Tedlar bag are less than 10% of the concentration maintained in the
shroud, then it is assumed that the integrity of the sampling train has not been compromised by
a leak.

Following the leak testing, the Summa canister will be allowed to collected a gas sample over
an approximate 10-minute period until the canister’s gauge shows a vacuum of approximately 4
to 5 inches mercury (inHg) remaining, at which point, the Summa canister’s valve will be closed
and the sampling stopped. It is understood that a vacuum of less than 10% of the starting
vacuum within the Summa canister at the end of sampling will not be acceptable.

The Summa canisters will be labeled and delivered under standard chain-of-custody procedures
to a qualified laboratory to be analyzed by EPA Method TO-15 (full list plus naphthalene). The
laboratory will be instructed to report Summa canister vacuum measurements at receipt and “J-
flag” concentrations for each sample. A request will be made to the laboratory for them to report
compound concentrations to the lower of the laboratory MDLs or to the extent possible, the
NCDEQ Residential SGSLs.

During each sample event, the following field QC sample will also be collected:
• DUPLICATE - a duplicate sample, analyzed by EPA Method TO-15 (full list plus
naphthalene) . The duplicate sample will be collected using a laboratory-supplied “T”
fitting.
• QA/QC purposes will be collected during each sampling event.

Sub-slab vapor sampling will be completed approximately 1-3 days after scheduled indoor air
sample events to avoid influences to indoor air from sub-slab vapor sampling activities.

4.3 Indoor Air Sampling

One round of indoor air sampling will be performed once the building is weather proof and the
HVAC systems are operational. At least 24-hours prior to collection of indoor air samples IAS-1
through IAS-10, a building walkthrough will be performed utilizing a photoionization detector
(PID) to attempt identification of potential background sources for VOCs such as construction
equipment, painting supplies, etc. An Indoor Air Building Survey form will be completed as part
of each sampling event. The indoor air samples will then be collected under closed-house
conditions (i.e., with operational HVAC) which will be maintained a minimum of 48-hours prior to
start of and throughout the sampling events.

The indoor air samples will be collected from a height of approximately 4 feet above the floor
surface using laboratory-provided individual-certified 6-liter Summa canisters. The samples will
be collected over an approximate 24-hour sample time. Sampling will be ended when vacuum
within the Summa canister reaches the target vacuum of around 4 to 5 inHg. It is understood
that a vacuum of less than 10% of the starting vacuum within the Summa canister at the end of

Tarmac Virginia Brownfields Property - Brownfields Project No. 26067-22-060 November 14, 2023
10
sampling will not be acceptable.

The Summa canisters will be labeled and delivered under standard chain-of-custody procedures
to a qualified laboratory to be analyzed by EPA Method TO-15 (full list plus naphthalene). The
laboratory will be instructed to report Summa canister vacuum measurements at receipt and “J-
flag” concentrations for each sample. A request will be made to the laboratory for them to report
compound concentrations to the lower of the laboratory MDLs or to the extent possible, the
NCDEQ Residential IASLs.

During each sample event, the following field QC samples will also be collected:
• One duplicate indoor air sample will be collected to be analyzed by EPA Method TO-15
(full list plus naphthalene). The duplicate sample will be collected using a laboratory-
supplied “T” fitting.
• One outdoor ambient air sample to be analyzed by EPA Method TO-15 (full list plus
naphthalene).

Weather conditions (ambient temperature, humidity, and barometric pressure readings) will be
recorded during each sampling event using the NOAA Charlotte weather station and hand-held
instruments. Sampling will not be performed on a rainy or exceedingly windy day.

The indoor air sampling results will be compared to current North Carolina Indoor Air Screening
Levels (IASLs) using the most recent version of the NCDEQ risk calculator to evaluate
cumulative potential vapor intrusion risks under the residential use scenario for each sample
location. Summary results of the sampling will be provided to NCBP as an Excel summary table.
In the event indoor air impacts are identified above applicable risk levels, an evaluation of the data
and proposed actions will be presented to NCBP for review and approval. These proposed actions
may include comparison of the sub-slab vapor sample results to the indoor air sample results at
specific areas of the building, evaluation of safety data sheets (SDSs) for potential off-gassing of
construction materials, conversion of the passive VIMS to an active VIMS, and/or resampling per
the direction of NCBP. Based on receipt of acceptable results, NCBP will issue an occupancy
decision for the Brownfields Property.

Results and analysis of the sub-slab vapor and indoor air sampling will be submitted to NCBP
as discussed in Section 7.0. If TCE is detected above the Residential SGSL in the sub-slab
samples, or if TCE is detected at any concentration in the indoor air samples, NCBP will be
notified of the results after receipt and validation of the analytical data.

5.0 POST-OCCUPANCY EFFECTIVENESS TESTING

As the system will be a passive VIMS and thus post-occupancy pressure testing will not be
performed.

Per NCDEQ DWM Minimum Mitigation and Sampling Requirements for Reuse (Draft February
2023 guidance), current plans call for post-occupancy indoor air quality and sub-slab vapor
testing to be performed semi-annually for two (2) years, during warm and cooler weather
conditions, following the sampling procedures described in Section 4.0, with samples to be
analyzed for select VOCs identified during pre-occupancy testing with concurrence from the
NCBP. Based on results of the post-construction/pre-occupancy testing and the first round of
post-occupancy sub-slab vapor and indoor air quality testing, the need for performing additional
rounds of semi-annual post-occupancy testing will be revaluated with the NCBP. It is
understood that if results of the first pre-occupancy testing and the first round of pos-occupancy
testing , including NCDEQ risk calculator results, indicate a lack of an applicable health risk, a
reduction in the number of post-occupancy sampling events noted above could be adjusted
following consultation with the NCBP.

If post-construction testing indicates the VIMS must be converted from a passive to an active
system, then 2 years of semi-annual post-occupancy effectiveness testing and pressure testing
will be completed. This would include the following, during the first year following completion of
construction of the building and operation of an active VIMS, vacuum measurements from vapor
pins # 1 through #15) will be recorded monthly for one quarter followed by quarterly for the
remainder of the year. Results of the vacuum measurements will be submitted to NCBP
quarterly. After the first year, the need to continue with the vacuum measurements associated
with the active VIMS will be discussed with NCBP.

6.0 FUTURE TENNANTS AND BUILDING USE

The future use of the proposed structure is multi-family residential apartments with associated
amenities. After occupancy, VIMS maintenance and upkeep will be the responsibility of the
building owner or property management group. If vapor mitigation components are damaged or
need to be altered for building renovations, the building owners or management will be
instructed to contact appropriate parties to conduct appropriate maintenance. An operation and
maintenance (O&M) Plan will be prepared by the engineer, or designee, certifying installation of
the VIMS that will include details of the VIMS construction and on-going maintenance. The
O&M Plan will be submitted to NCBP for review. The O&M Plan is anticipated to be prepared
and submitted to NCBP for approval prior to building occupancy.

The O&M Plan will require that a NC PE be contacted to oversee or inspect any modifications or
repair activities to the VIMS, and a letter shall be submitted to NCBP by the building owner or
property management group detailing the repairs or modifications.

7.0 REPORTING

Results of the post-construction pilot/influence testing and the sub-slab vapor and indoor air
sampling events will be provided within 60 days following completion of the sampling to NCBP in a
report summarizing completed field activities including sampling procedures and sample locations,
and field conditions, along with summary tables, photographs, and our conclusions and
recommendations. Based on acceptable results as documented in the report(s), NCBP will
issue an occupancy decision for the Brownfields Property.

A VIMS Installation Completion Report (sealed by a NC PE) documenting installation activities
associated with the VIMS will be submitted to NCBP following confirmation that the mitigation
system is installed and effectively mitigating potential vapor intrusion risks to building occupants.
Upon preparation of the completion report, the reviewing engineer will provide their opinion as to
whether the VIMS’s effectiveness meets the design intent and applicable regulations. The report
will include a summary of VIMS installation activities such as representative photographs and
as-built drawings, QA/QC and smoking testing activities, SDSs of materials used in
construction, VIMS effectiveness testing results, and inspection documents. The report will also
include a NCBP approved engineer’s statement as to whether the VIMS was installed in
accordance with the NCBP approved VIMS plan and is protective of public health as evidenced
by the VIMS inspections, results of analytical testing, and QA/QC measures as described in this
VIMS plan. Potential PE pre-approved deviations from the approved design will be provided in
the report.

The pending Notice of Brownfields Property for the Site is anticipated to include standard land
use restrictions that indicate the building(s) shall not be occupied until NCBP provides written
compliance approval for the installation and performance of the VIMS as documented in the
installation completion report. However, we understand that NCBP may provide conditional
approval with submittal of a data summary package in lieu of the full VIMS Installation
Completion Report, if warranted, based on timing of the proposed building occupancy and
report review times. No occupancy of the building can occur without prior written approval of
NCBP, with the decision based on the post-construction/pre-occupancy sub-slab vapor and
indoor air sampling results.

TECHNICAL DATA
North America: 847.851.1800 | 800.527.9948 | www.cetco.com
DESCRIPTION
VI-20™ is a 7-layer co-extruded geomembrane
made using high quality virgin-grade polyethyl-
ene and EVOH resins that provide unmatched
impact strength as well as superior resistance
to VOC vapor transmission. EVOH technol-
ogy serves as a highly resilient underslab
and vertical wall barrier designed to restrict
methane, radon and other harmful chemi-
cals. Applications for EVOH originated in the
manufacturing of automotive fuel systems to
control emissions of hydrocarbons, whose use
was mandated by the US EPA and the CA Air
Resources Board (CARB) to reduce VOC emis-
sions.
APPLICATION
VI-20™ is a 20-mil, high performance poly-
ethylene-EVOH copolymer geomembrane,
specially designed for use as a VOC barrier
when used in conjunction with Liquid Boot®
spray-applied vapor intrusion membrane to
minimize vapor intrusion and nuisance water
(non-hydrostatic conditions) migration into
buildings. VI-20™ is ideal for applications with
chlorinated solvents, BTEX and other PAHs.
BENEFITS
• Polyethylene layers provide excellent chemi-
cal resistance and physical properties
• EVOH barrier technology provides superior
protection against diffusion of chemicals
when compared to typical HDPE geomem-
branes
• Manufactured at ISO 9001:2008 certiied
plant
INSTALLATION
For use as a component of the Liquid Boot®
Plus system, VI-20™ geomembrane is rolled
out on prepared sub-grade, overlapping
seams a minimum of six inches (6”). The geo-
membrane is cut around penetrations so that
it lays lat on the sub-grade and tight at all in-
side corners. A thin (20 mil) tack coat of Liquid
Boot® (“A” side without catalyst) is sprayed
within the seam overlap. Once the VI-20™ geo-
membrane is installed, penetrations are then
treated with VI-20™ Detailing Fabric prior to
installation of the Liquid Boot® spray-applied
vapor intrusion membrane and UltraShield™
G-1000 protection course.
PACKAGING
VI-20™ Geomembrane is available in the fol-
lowing packaging option:
• 10 ft. x 150 ft. (3 m x 45 m) Rolls
VI-20™ GEOMEMBRANE
HIGH-PERFORMANCE VAPOR INTRUSION BARRIER
EVOH technology provided in VI-20™
geomembrane has been shown to have VOC
diffusion coeficients 20 times lower than an
80 mil (2 mm) HDPE geomembrane.

DESCRIPTION
LIQUID BOOT® is a seamless, spray-applied,
water-based membrane containing no VOCs,
which provides a barrier against vapor intru-
sion into structures. LIQUID BOOT® is installed
under slab and on below grade vertical walls
as a gas vapor barrier to minimize vapor and
nuisance water migration into buildings. LIQ-
UID BOOT® spray-application directly to pen-
etrations, footings, grade beams, pile caps
and other irregular surfaces, provides for a
fully-adhered gas vapor barrier system.
APPLICATIONS
LIQUID BOOT® is used as an underslab and
below-grade vertical wall gas vapor barrier,
used to minimize vapor and nuisance water
(non-hydrostatic conditions) migration into
buildings. LIQUID BOOT® is ideal for methane
migration control. LIQUID BOOT® is also NSF®
certified for use as a potable water liner in
concrete water reservoirs and tanks greater
than 300,000 gallons to protect the concrete
from water seepage.
BENEFITS
• Spray-application provides excellent sealing
of penetrations, eliminating the need for
mechanical fastening
• Seamless, monolithic membrane elimi-
nates seaming-related membrane failures
• Unique formulation provides superior pro-
tection from methane gases and water va-
por
• Fully adhered system reduces risk of gas
migration

1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
The RP and XP Pro Series Radon and Vapor Intrusion (VI) Fans are intended for use by trained, professional, certified/
licensed radon mitigators. The purpose of these instructions is to provide additional guidance for the most effective
use of RP and XP Series Fans. These instructions should be considered supplemental to EPA/radon industry standard
practices, state and local building codes and regulations. In the event of a conflict, those codes, practices and
regulations take precedence over these instructions.
1.2 FAN SEALING
The RP and XP Pro Series Radon and VI Fans are factory sealed; no additional caulk or other materials are required
to inhibit air leakage.
1.3 ENVIRONMENTALS
The RP and XP Pro Series Radon and VI 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.

1.4 ACOUSTICS
The RP and XP Pro Series Radon and VI Fans, when installed properly, operate 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 inline 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(s). The RP and XP Pro Series Radon Fans are not suitable for kitchen range hood
remote ventilation applications.)
1.5 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 and XP Pro Series Radon and VI Fan. The lack of cooling air may result in
the fan cycling on and off as the internal temperature rises above the thermal cutoff. Should this condition arise,
it is recommended that the fan be turned off until the water recedes, allowing for return to normal operation.
1.6 SLAB COVERAGE
The RP and XP Pro Series Radon and VI Fans 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 and XP Pro Series Radon and VI Fan
best suited for the sub-slab material can improve the slab coverage. The RP and XP Pro Series Radon and VI Fans
have a wide range of models to choose from to cover a wide range of sub-slab materials. The RP140 and 145 are
best suited for general purpose use. The RP260 can be used where additional airflow is required, and the RP265 and
RP380 are 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.

1.7 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
and XP Pro Series Radon and VI 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 and XP Pro Series Radon and VI Fans are NOT suitable for underground burial.
For RP and XP Pro Series Fan piping, the following table provides the minimum recommended pipe diameter
and pitch under several system conditions.
*See p. 7 for detailed specifications.

Diameter
Minimum Rise per Ft of Run*
@25 CFM @50 CFM @100 CFM
4”1/8”1/4”3/8”
3”1/4”3/8”1 1/2”
1.8 SYSTEM MONITOR & LABEL
A System Monitor, such as a manometer (P/N 50017) or audible alarm (P/N 28535, 28001-2, 28001-4 or 28421),
is required to notify the occupants of a fan system malfunction. A System Label (provided with Manometer P/N 50017)
with instructions for contacting the installing contractor for service and identifying the necessity for regular radon tests
to be conducted by the building occupants must be conspicuously placed in a location where the occupants frequent
and can see the label.
1.9 ELECTRICAL WIRING
The RP and XP Pro Series Radon and VI Fans operate on standard 120V, 60Hz AC. All wiring must be performed
in accordance with National Fire Protection (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 UL 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.
1.10 SPEED CONTROLS
The RP and XP Pro Series Radon and VI Fans are rated for use with electronic speed controls; however, speed controls
are generally not recommended. If used, the recommended speed control is Pass & Seymour Solid State Speed
Control (Cat. No. 94601-1).

2.0 INSTALLATION
The RP and XP Pro Series Radon Fans can be mounted indoors or
outdoors. (It is suggested that EPA and radon mitigation standards
recommendations be followed in choosing the fan location.) The RP
and XP Pro Series Radon and VI Fans may be mounted directly on the
system piping or fastened to a supporting structure by means of an
optional mounting bracket. The ducting from the fan to the outside of the
building has a strong effect on noise and fan energy use. Use the shortest,
straightest duct routing possible for best performance, and avoid installing
the fan with smaller ducts than recommended. Insulation around the
ducts can reduce energy loss and inhibit mold growth. Fans installed with
existing ducts may not achieve their rated airflow.
2.1 MOUNTING
Mount the RP and XP Pro Series Radon and VI Fan vertically with outlet up.
Ensure 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 and XP Pro Series Radon and VI Fans may be optionally secured with the
RadonAway Fan Mounting Bracket (P/N 25007). 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 a means of disconnect for
servicing the unit and for vibration isolation. As the fan is typically outside of the
building thermal boundary and is venting to the outside, installation of insulation
around the fan is not required.
2.4 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper connections (See Section
1.9). Note that the fan is not intended for connection to rigid metal conduit.
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 & ANNUAL SYSTEM MAINTENANCE
______ Verify all connections are tight and leak-free.
______ Ensure the RP and XP Pro Series Radon and VI Fan and all ducting are secure and vibration-free.
______ Verify system vacuum pressure with manometer. Ensure vacuum pressure is within normal
operating range and less than the 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 and applicable testing standards.

APPENDIX F
VIMS Design Checklist Version 1, March 2022
Vapor Intrusion Mitigation System (VIMS)
Design Submittal Requirements
NCDEQ Brownfields Program – March 2022

In order to more efficiently process and approve VIMS designs, the Brownfields Program has standardized the format for design
submittals. We have generated this format in the form of a checklist to allow for ease in submittal by the prospective developer’s
consultant and the Brownfields Program’s completeness review. The checklist below outlines the minimum requirements and
submittal format under the Brownfields Program for VIMS system design considerations and reporting. All VIMS design submittals
to the Brownfields Program must include this completed checklist in this required format. Strictly adhering to these design
submittal requirements will allow DEQ to minimize its review time for the design and the scope of performance and pre-
occupancy sampling wherever possible. However, if these requirements are not followed fully, DEQ will require a more
extensive and on-going sampling protocol to ensure that the VIMS is fully protective of public health. For the purposes of
these requirements, PE shall mean a Professional Engineer licensed in North Carolina.

The benefits of following these requirements include:
- Significant Professional Engineering design discretion by a PE as to the VIMS design;
- Minimal turnaround time as the Brownfields Program review will consist of a completeness check rather than a
detailed design review;
- Pre- and post-occupancy sampling location and frequency minimization and the lowest possible frequency of pre-
/post-occupancy sampling to confirm system efficacy, at DEQ’s discretion; and
- Potential reduction in long term monitoring requirements and costs.

If these requirements are not followed, and the VIMS design fails a completeness check:
- Significant delays and associated costs may be incurred as DEQ conducts an in-depth review;
- Subsequent design modifications and costs of delay associated with multiple review iterations; and
- The establishment of extensive ongoing sampling requirements to ensure adequate system performance and
public health protection.

Please note that this VIMS design submittal is not the end of communication with the Brownfields Program. Best practices
for successful project completion and avoiding installation/construction delays include maintaining close coordination and
consultation with the Brownfields Program between the PD, VIMS contractors, and all general contractors for the
installation of the design. This will avoid costly construction delays and installation issues that would trigger additional
monitoring requirements that otherwise would not be necessary. It is important that significant advance notification of
schedules, and subsequent rescheduling as it occurs, for the following activities (at a minimum) is provided to the
Brownfields Program:

- Project construction;
- Design modification/addenda;
- Installation;
- Performance testing; and
- Inspections

Note: The format below should be followed verbatim in its entirety in the VIMS design submittal to satisfy and facilitate the
completeness review performed by the DEQ Brownfields Program. In addition, this document is to be completed and
submitted as a checklist along with the design to ensure the necessary elements are addressed in the design.

2
VIMS Design Checklist Version 1, July 2021
☒ Section 1. Introduction
Provide a brief background of the Brownfields Property and basis for installing a VIMS (e.g. off-site migration of
contaminants, on-site releases, chlorinated solvents, pre-emptive approach for residential redevelopment, etc.). Document
the type of foundation design required by construction plans (e.g. waffled construction, ground floor post-tension cabling,
build-to-suit construction, or other unique construction plans). Additional items to be included in the VIMS design
submittal must include:

☒ Brownfield Project ID#, Parcel #s, address(es), site history, approximate acreage of site, and contact
information for the developer, consultant, VIMS installation contractor, and Brownfields Project Manager.
☒ If vapor mitigation is not proposed for all buildings (new, existing, or partial building), provide a risk-based
justification for why mitigation is not needed for all buildings (note that confirmatory sampling of unmitigated
areas may be required post construction/renovation).
☒ Discussion of proposed site redevelopment (e.g., townhomes, apartments, commercial, mixed-use, retail, etc.),
and general layout of building(s) - (e.g., garage on first floor, with living space on second and third floors,
presence of elevators, former textile mill with ground floor and basement level apartments, podium parking first
floor, 10 story apartment building with podium parking on first three floors, etc.).

Include references to the following figures (to be included in the Figures section outlined below):
☒ Site vicinity map
☒ Figures detailing all existing and/or proposed buildings overlain on historical sampling locations/known
impacts
☒ Figures detailing the approximate ground floor square footage, including square footage of area proposed for
mitigation (if different), of relative buildings and their proposed use per floor. Include footprint of planned
demolition or retention of existing buildings.
☒ Locations of thickened footers, separate slabs, etc. that may hinder communication between slab segments
☒ Locations of relevant mitigation features (including but not limited to extent of vapor barrier, suction lines,
risers, extraction points, pressure monitoring points, etc.)
☒ Locations of vertical walls in contact with soils (and a statement regarding whether any such features exist or
not)
☒ The Design and any figures as appropriate have a PE Seal using the following language:

“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 [add “and its installation” for use in an installation report] is [are]
fully protective of public health from known Brownfields Property contaminants.”

Note: If a VIMS is not installed for certain portions of a Brownfields Property due to open-air ‘podium’ construction or
parking decks, a VIMS may still be required for features such as elevator shafts, stairwells, and/or areas with utility
penetrations that exchange air with occupied areas. Confirmatory sampling of these areas and associated occupied spaces
may be required during post construction/renovation.

3
VIMS Design Checklist Version 1, July 2021
☒ Section 2. Design Basis
Specify which type(s) of VIMS is intended for the planned structures, selecting which is appropriate, and explaining the
basis for the selection:
☒Passive System. Note for all passive systems, a mechanism/process shall be established (to be approved by
DEQ) by which the system can be made active, which may include a reliance on information from pressure
measurements, soil gas and/or indoor air sampling, or changes in site conditions. A passive system should be
designed and installed such that the passive system is as effective as an active system at preventing vapor intrusion.
☐Active System. Note a pressure differential resulting in depressurization below the slab of 4 pascals or greater at
remote extents of each VIMS area is considered sufficiently depressurized (low pressure readings such as 1 to 2
pascals may be acceptable if employed with continuous pressure measurement during varied HVAC situations,
weather events, and climate for winter and summer months). An overview of the alarm system that informs
appropriate parties in the event the system malfunctions should be included.

Note: Pressure monitoring points are recommended to be placed at locations remotely distant from where each suction point
transitions to below the slab in addition to locations positioned near each suction point and associated horizontal piping. If
monitoring points are not installed at remote locations, future sampling requirements may necessitate installation of
additional monitoring locations or an evaluation of indoor air quality.

For all system designs, the following design specifications must be included as exhibits:
☒ Sub-slab Venting Construction Materials and Installation. Design specifications must be included as an exhibit
(see Section 8 below). All piping, including above a roof line must be labeled at intervals no greater than 10 linear
feet permanently labeled with Vapor Intrusion Mitigation System” with contact information for questions or
repairs.
☒ Membrane Vapor Barrier Construction Materials and Installation. Design specifications must be included as an
exhibit (see Section 8 below). Particular attention should be paid to the design and diagrams for sealing barriers at
slab penetrations and edges. Note: Brownfields Property contaminants of concern (COCs) must not be present in
building materials.

Note: If materials are proposed that are not specifically rated for chemical resistance to specific site contaminants of
concern, this will have a bearing on DEQ’s determination of performance testing requirements following construction.
Specification documentation should be provided for all materials utilized as part of the VIMS.

Note: All utility penetrations are required to include trench dams. Include details on trench dam installation as part of
system design.

☒ Section 3. Quality Assurance / Quality Control
☒ Details on planned inspections are required for all gravel & piping prior to installing the vapor barrier, and are
required for all sections of the vapor barrier prior to pouring the slab. These inspections must be conducted by
qualified personnel under the supervision of the design PE and include field logs and photographs.
☒ A statement committing to provide a minimum of 2 business days’ advance notification to the Brownfields
Program prior to inspections should be included.
☒ Smoke Testing and/or Thickness (Coupon) Measurements: Smoke testing is strongly recommended for both
roll-out and spray applied barriers. Coupon testing will be required on spray application barriers only.

Note: Non-performance of adequate inspections or smoke testing will have a bearing on DEQ’s determination of
performance testing requirements following construction.

4
VIMS Design Checklist Version 1, July 2021
☒ Section 4. Post-Construction / Pre-Occupancy Effectiveness Testing
☒ Discussion of Pilot/Influence Testing is required for passive and active systems prior to occupancy with the
objective being to document that all areas below the slab can be effectively influenced by the current piping
network. Testing details should include, at minimum:
☒ Pressure monitoring points: Note based on pilot testing results and review by the Brownfields Program,
the number of pressure monitoring points installed for pilot testing may ultimately reduce the number of
permanent pressure monitoring points.
☒ Pressure monitoring points are placed at locations that are demonstrated to be remotely distant
from where each suction point transitions and are located at the extents of the area of influence to
below the slab in addition to locations near each suction point and associated horizontal piping
☒ Sub-slab vacuum monitoring and/or sample collection points: Note these should be installed PRIOR to
installation of floor slab(s). Drilling through concrete slabs and VIMS barriers after a concrete slab is in
place may result in significant issues regarding the sealing of the sampling point to the VI barrier once the
concrete slab has been poured.
☐ A statement committing to provide a minimum of 2 business days’ advance notification to the
Brownfields Program prior to inspections should be included.

☒ Discussion of pour back areas including:
☒ Protection of and testing following completion: Note if concrete pour back areas for future tenants are
included in the VIMS design or if slab modifications are made in the future, communication testing will be
required after completion of each of the following events: 1) in the event TCE is present, preventative
measures implemented when the barrier is removed, 2)once the pour back area VI barrier has been installed,
3) following completion of tenant up-fit activities, 4) prior to pouring the concrete floor slab, and 5)
following repair of any damage to the VI barrier.
☒ Commitment to DEQ notification of a minimum of 2 business days prior to the start of tenant up-fit
activities.
☒ Discussion regarding sampling/protective measures that will be taken if a building is occupied during up-
fit activities.

Note: Section 3 (Quality Assurance/Quality Control) above will apply to all future pour backs and slab modifications; these
requirements apply to all system or slab alterations regardless of how small the altered area. If pour-back area
communication testing is not deemed sufficient prior to floor slab being poured, this will result in the need for additional
sampling. Alteration of pour back areas or alteration of slabs in the future may necessitate future sampling of the site
buildings.

☒ Discussion of protection of exposed systems: During any time that the system is left exposed (i.e. without a
concrete/wooden cover in place), protective measures must be implemented, as noted above, and scheduled
inspections of the exposed system are required. In addition to the pre-occupancy testing, during the time that the
system is left exposed, monitoring, including vapor intrusion assessment, will be conducted in the subject building.
If PCE, TCE, and/or select daughter products are present at the Brownfields Property, indoor air sampling will be
required.
☒ Discussion of proposed pre-occupancy soil gas and/or indoor air sampling: Sampling is to be completed prior
to occupancy and the data will be compared to applicable DEQ screening criteria. Include considerations for
resampling in the event that impacts are identified above applicable criteria. Note: Unlike the remainder of this
document, which has significant PE discretion in design; soil gas/indoor air sampling frequency and locations is
subject to the sole discretion of the DEQ Brownfields Program.

Note: Pilot/Influence Testing, Soil Gas, and/or Indoor Air Sampling must be submitted to the Brownfields Program for
conditional occupancy considerations as per standard Brownfields VI provisions.
5
VIMS Design Checklist Version 1, July 2021
☒ Section 5. Post-Occupancy Effectiveness Testing – Should be specified with the design submittal and not
at a later date.
☒ Discussion of On-going Pressure Testing: Note this is required for active systems to be conducted on a
monthly basis for the first year with collected information submitted to the Brownfields Program on a quarterly
basis (or via telemetry data submittals on a basis as pre-approved by DEQ). Based on the first year of pressure
readings, and with approval of the Brownfields Program, pressure testing may be collected quarterly (see below)
and data would be submitted with the annual Land Use Restriction Update (LURU) following the first year of data
collection. Note that the Brownfields Program utilizes a ‘sliding scale’ of pressure reading collection frequency vs.
the stated depressurization goal or observed depressurization (e.g., if a VIMS is designed (or observed) to obtain a
pressure differential less than 4 pascals, more frequent depressurization measurements will be necessary and may
include continuous data logging; or an upgrade to the VIMS to increase pressure differentials may be necessary).
☒ Discussion of proposed post-occupancy sub slab vapor and/or indoor air sampling: Sampling is to be completed
post occupancy and the data will be compared to applicable DEQ screening criteria. Include considerations for
resampling in the event that impacts are identified above applicable screening criteria. Note: Unlike the remainder
of this document, which has significant PE discretion in design; sub slab vapor/indoor air sampling frequency and
locations is subject to the sole discretion of the DEQ Brownfields Program.

Note: In addition to these requirements, townhomes remain subject to the sampling requirements outlined in the DEQ
Brownfields Townhome Minimum Requirements located at www.ncbrownfields.org. Ensure that Townhome
redevelopment has been approved by the NC DEQ Brownfields Program in advance of redevelopment planning.

☒ Section 6. Future Tenants & Building Uses
This section must address plans to notify future tenants of the presence of a VIMS and to prevent future tenants or
occupants from exposing/damaging the VIMS without the oversight of a qualified P.E. Note that if the VIMS is
exposed (for installation of new utilities, etc.), the same inspection requirements and reporting as for initial
installation is required.

☒ Section 7. Reporting
This section must discuss reporting deliverables within 60 days following completion of initial post-construction testing as
outlined in Sections 4 and 5 above and a commitment to include in the final deliverable:
☒ A report prepared and submitted to the Brownfields Program under PE seal
☒ Summary of the installation, QA/QC measures, post-construction/pre-occupancy system effectiveness testing
☒ A statement from the PE providing an opinion of whether the VIMS was delivered in a condition consistent with
the VIMS design and objectives. Note: Certain components of these reporting requirements, including pressure
measurements, sub slab vapor sampling, and indoor air sampling, can be conducted and reported under a N.C.
licensed Professional Geologist seal.
☒ Appendices to include at minimum:
☒ as-built drawings (also signed/sealed by a PE);
☒ all inspection logs including photographs and field logs. Note that the inspection logs do not need to be
addressed in the text of the report unless information pertinent to the operation of the VIMS was discovered; and
☒ An index of, and individual safety data sheets for, any materials used during construction that could
contribute to background indoor air contamination.
☒ PE sealed statement regarding the system effectiveness verbatim as follows:

“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)

☒ Section 8. Design Submittal Exhibits
Drawings to be included:
☒ General Site Location Map (to include a scale and north arrow)
☒ Site Figure that includes:
☒ The Brownfields Property boundary and immediately adjacent properties or landmarks such as
streets;
☒ Graphic scale and north arrow;

and if available on-site or adjacent surface water locations) relative to existing and proposed structures;
and
☒ Reference to table(s) in the VIMS Plan where analytical results are provided. These results should
be compared to the appropriate screening criteria (residential or non-residential IASL’s, etc.).
☒ Design Specifications: Sub-Slab Venting Construction Materials and Installation; Membrane Vapor
Barrier Construction Materials and Installation
☒ Material Specification Sheets for all items associated with the VIMS (vapor barrier, piping, mastic, tape,
sealants, cleaners, etc.)

☒ Section 9. Special Considerations for Retrofits
The following details will need to be provided for DEQ review for a planned retrofit of existing buildings:
☐ Complete explanation of subsurface structural conditions on all site buildings, including those buildings that are
not proposed for mitigation but will remain on-site including but not limited to details on the presence or absence of
the following:
☐ Basements/crawlspaces;
☐ Vertical walls in contact with soil;
☐ Details on slab thickness and underlying conditions (i.e. slab on gravel, slab on grade, slab over
crawlspace, etc.);
☐ Details on number of slabs per building that are connected that have differing thicknesses or thickened
footer separations or sub-walls that would create isolated slab areas for consideration or would hinder overall
VIMS influence;
☐ Obvious issues with slab integrity such as cracks or voids, etc.);
☐ Presence of sub-slab utility conduits, trenches, or tunnels that could act as preferential pathways and the
need to mitigate (e.g. installation of trench dams, anti-seep collars, etc.);
☐ Sumps;
☐ Elevator pits; and
☐ Other applicable subsurface building features.

☐ Details on proposed sealing/repairs of obvious/existing concrete slab from minor caulking of floor
cracks/expansion joints, and VIMS core drilled suction points, to possible VIMS saw cut trench sealing or
specialized coatings for entire floor slab (e.g. Retro-CoatTM or other similar coatings).
☐ Details on radius of influence in pilot/communication testing planned.
☐ Existing buildings to remain as part of redevelopment and/or proposed buildings shown on the Site Plan should
be accurate and complete. At a minimum, plans should provide the following details:

VIMS Design Checklist Version 1, July 2021
☐Detailed foundation plans - In addition to displaying piping network and proposed monitoring point
locations, foundation plans should show all footers, grade beams, and other sub-slab features that could
affect vacuum communication. This would also include sub-grade crawl spaces, basements, tunnels, walk-
out basements, elevator pits, and other situations where soil is in contact with side walls of structure in
addition to below the footprint of the building slab. Provide details on any vertical walls in contact with soil
and the planned mitigation of such.
☐Drawings shall be provided of each VIMS barrier sealing detail, including piping layout (transition from
slotted PVC, terra vent, etc. to solid piping through grade beams for example, and examples of these detail
drawings should be called out on VIMS layout drawing. When possible, drawings should be provided in
color so that VIMS piping, extents of proposed vapor barrier, proposed sample/vacuum monitoring locations
and other features can be easily distinguished.
☐Detailed drawings of grade beams, thickened slabs, and other sub-slab features that could affect VIMS
influence must be clearly defined and easily discernable from existing or proposed interior walls that are
above the floor slab (which would have no effect on vacuum influence below the slab).
