Vapor Mitigation System Construction Details
Former Dana/ex Facility
515 E.AlabamaAvenue
Bessemer City, North Carolina
In January 2023, Harmon Environmental, PA and PGP Services, LLC initiated the construction of
a vapor mitigation system at the former Danalex industrial/commercial facility at 515 E. Alabama
Avenue in Bessemer City, North Carolina. Figure 1 depicts the location of the site on an excerpt
of a United Stated Geologic Survey (USGS) topographic map of the region.
This vapor mitigation system was designed and constructed to address historic sub-slab soil
contamination documented beneath Area 5 of the on-site structure (Figure 2).
2. 0 System Installation Activities
Based on the pilot test results, Harmon Environmental, P A and PGP Services, LLC. installed a
mitigation system consisting of 28 vapor extraction points (Figure 3). The number and location
of these extraction points was designed in an effort to overcome the heterogeneity of the floor slab.
With the exception of the two points located in the maintenance area, each point was installed
within approximately 5 feet from an existing structural column. Each point consists of
approximately 1-foot square hole through the concrete floor slab. Following removal of the
concrete material, an approximately 1-cubic foot of soil was excavated beneath the slab at each
location and the void was backfilled with No. 57 stone (Figure 4).
A 4-inch diameter Schedule 40 PVC pipe equipped with a Maurice Franklin® 4-inch round screen
vent cover was installed on a 4-inch diameter Schedule 40 PVC header pipe flush with the base of
the concrete floor. Following installation of the header pipe, the open area of the floor was covered
with a VaporBlock® Plus™ VBP20 vapor barrier sealed to the concrete floor using VaporSeal™
tape and Butyl Seal2-sided tape in accordance with the manufacture's specifications.
Each 4-inch PVC Schedule 40 header pipe extended through the respective floor trench to the
adjacent structural column. Each floor trench was subsequently sealed with a VaporBlock®
Plus™ VBP20 vapor barrier to the concrete floor using VaporSeal™ tape and Butyl Seal2-sided
tape in accordance with the manufacture's specifications.
Following installation of the vapor barrier, the trench and mitigation point were backfilled with
5000 PSI concrete finished flush with the existing floor.
At the structural columns, each header pipe extends vertically to a height of approximately 4-feet
above thr.;: floor where individual PressureTech™ PT-25 fan was installed. These fans operate
Direct Current (DC) electric motors to reduce electrical consumption. Between the fan and the
floor at each location an individual Fantech Model No. 498290 water column (WC) Vacuum
Alarm was installed. These alarms are calibrated to notify occupants of the building in the event

the vacuum in an individual header pipe drops below 0.20-inches of water.
The fans operate on 110-Volt electrical supply provided at each location by Benmar Properties,
LLC personnel. The alarms are provided electrical power from three AAA batteries each.
2-inch diameter schedule 40-PVC header piping deliver the sub-slab air from each of the
PressureTech™ fans to header exhaust piping located on the southeast wall of Area 5. These 2-
inch header pipes were suspended from the roof structure with an approximate 1% slope toward
the sub-slab points.
Four 4-inch diameter Schedule 40 PVC header pipes were installed in the roof structure along the
southeastern wall of Area 5. These four headers receive the air vented from individual abatement
points and deliver it through the exterior building wall to exhaust pipes outside the building.
The manufacturers documents for the equipment are presented in Attachment A.
To test the systems effectiveness, Harmon Environmental, PA personnel installed 10 Vapor Pin™
permanent sub-slab vapor sample points through the floor of Area 5 (Figure 3). These sample
points were constructed with stainless-steel Vapor Pins™ and stainless-steel protective covers.
3.0 System Vacuum Testing
The vapor mitigation system was started on March 24, 2023. Electrical issues impede four vents
from being started until March 27, 2023. Following electrical service repair, vacuum
measurements were collected from beneath the floor slab in Area 5 using a TSI 9565-P
Anemometer. The field vacuum measurements are presented in Table 1.
4. 0 Indoor Air Sampling Activities
On Aprill2, 2023 after allowing the building time to equilibrate following system startup, Harmon
Environmental, P A personnel collected 11 indoor and one background air sample from the site
using Suma™ canisters equipped with 8-hour regulators.
Air sample 897 AI was collected from the fence near the western comer of the former Danalex
structure with Suma® Canister No. 42648 and Flow Controller No. 13141 provided by Waypoint
Analytical LLC. The sample was collected from the approximate location depicted on Figure 5.
The intake height of the sampler was 59-inches above the ground. This test was initiated on April
12, 2023 at 08:11 with an initial vacuum measurement of 30.5 inches of Mercury (in Hg) and
terminated at 15:36 on Aprill2, 2023 with a final vacuum measurement of9 in Hg. The ambient
barometric pressure and temperature were measured four times during the testing period (Table

5. 0 Indoor Air Sample Analytical Results
The analytical results associated with the April 12, 2023 indoor air samples are summarized in
Table 3. The laboratory data report and Chain-of-Custody Record are presented in Attachment B.
As indicated by this data, 1 ,2-dichloroethane and trichloroethene were detected in the facility at
concentrations exceeding the Non-Residential Screening level as revised by the North Carolina
Department of Environmental Quality (NCDEQ) in January 2023.
The detection oftrichloroethene in the indoor air samples appears to be associated with the known
conditions beneath the slab in Area 5 of the on-site building. The detection of 1,2-dichloroethane
is suspected to be associated with materials stored in the facility by the tenant.
Exceedance of the screening level triggers the use of the North Carolina Department of
Environmental Quality Risk Based Calculator (Revision January 2023) to evaluate conditions at
the site.
On May 2, 2023, Harmon Environmental, PA utilized the North Carolina Department of
Environmental Quality Risk Based Calculator (Version January 2023) to evaluate the results of
the April 2023 sampling event. The results of the Risk Based Calculator are included in Table 4
and in Attachment C. The Risk Calculator results indicated that none of the 12 samples exceeded
the Carcinogenic Risk Threshold of 1.0E-4 or a Hazard Index of 1.0 for Non-Residential Workers
for the targeted compound.
6. 0 Conclusions and Recommendations
Based on the April 12, 2023 analytical data, the mitigation system appears to be effective in
reducing the indoor air concentrations of targeted volatile organic compounds to below the
respective Non-Residential Workers risk thresholds. To protect building occupants, Harmon
Environmental, P A and PGP Services, LLC recommend the system be inspected weekly to verify
the PressureTech™ fans and FanTech™ sensors are operating and the header piping is intact. An
Inspection Log documenting these inspections should be maintained at the facility. In the event
an inspection indicates portions of the system are not functioning or have been compromised,
repairs should be implemented immediately. In the event the entire system is not operational (i.e.
electrical power failure, etc.), employees should not enter the building until the system operation
is returned.
In addition to weekly inspections, quarterly indoor air samples should be collected quarterly for 2
years. Should the results of these sampling events indicate the indoor air quality is stable, this
sample schedule may then be modified to semi-annual or annual events.
The proposed routine sampling events results should be reviewed to evaluate the effectiveness of
the mitigations system.

Radon Alarm
Pressure Sensor, Visual & Audible Alert, 3"/4"/6" PVC Pipe
Item #: 498290
Designed to measure pressure differential changes, the Radon Alarm
notifies homeowners when their Active Soil Depressurization radon
reduction system fails.
The Radon Alarm measures the suction pressure -not the radon levels -
of the Active Soil Depressurization (ASD) system. It exceeds AARST
requirements by including a clear & distinct audible notification and a
visual light notification that is vividly observable-consisting of green,
yellow, & red LED lights.
Additionally, this alarm gives mitigators added control by utilizing two (2)
dip switches to set audibility function and alarm delay time. No pre­
installation action is required if the factory default settings meet the
application requirements.
Provides an extra measure of protection:
• Alerts the user with audio and visual notifications of malfunctioning
system
• Gives mitigators added flexibility & control by utilizing two (2) dip
switches
• Accurately measures suction pressure
• Curved product design to allow for direct pipe mounting
• Prevents false notifications by delaying alarm for a 24/96-hour time
period
• Snooze capability silencing the audible alarm notification for one (1) week
Fast & Easy installation:
• Designed to be installed on a 3", 4", or 6" PVC pipe with a direct pipe connection
• Foam mounting tape provides an airtight seal at installation point
• Indoor use only where alarm can be easily seen

The Radon Alarm includes two (2) AAA batteries. It is recommended that the batteries be replaced every 2-3 years or after any alarm activation. When the
Radon Alarm batteries are low, a yellow LED light will blink every five (5) seconds with a chirping sound (if alarm audibility is enabled).

VAPORBLOC~ PLUSTM VBP20 RAvE N
UNDER-SLAB VAPO R I GAS BARRIER
PRODUCT DESCRIPTION
VaporBiock® Plus™ is a seven-layer co-extruded barrier
made using high quality virgin-grade polyethylene and
EVOH resins to provide unmatched impact strength as well
as superior resistance to gas and moisture transmission.
VaporBiock® Plusr" 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.
VaporBiock® Plus™ 20 multi-layer gas barrier is manufactured
with the latest EVOH barrier technology to mitigate hazardous
vapor intrusion from damaging indoor air quality, and the safety
and health of building occupants. VBP20 is one of the most
effective underslab gas barriers in the building industry today
far exceeding ASTM E-17 45 (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.
VaporBiock® Plusr .. 20 is produced within the strict guidelines
of our ISO 9001 Certified Management System.
PRODUCT USE
VaporBiock® Plus™ 20 resists gas and moisture migration
into the building envelop when properly installed to provide
protection from toxic/harmful chemicals. It can be installed as
part of a passive or active control system extending across the
entire building including floors, walls and crawl spaces. When
installed as a passive system it is recommended to also include
a ventilated system with sump(s) that could be converted to an
active control system with properly designed ventilation fans.
VaporBiock® Plusr" 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
VaporBiock® Plus™ 20 is available in 10' x 150' rolls to
maximize coverage. All rolls are folded on heavy-duty cores
for ease in handling and installation. Other custom sizes
with factory welded seams are available based on minimum
volume requirements. Installation instructions and ASTM E-1745
classifications accompany each roll.
