1.0 SITE DESCRIPTION

1.1 Purpose of Indoor Air Sampling

Terracon has completed indoor air sampling activities, as required by the Environmental
Management Plan (EMP) for the site (see below for site description and history). The sampling
was conducted in accordance with the Indoor Air Sampling Work Plan, which was approved by
NCDEQ via a Work Plan Approval letter, both dated February 23, 2021. The PD recently
completed modifications to the existing sub-slab depressurization system at the on-site building,
which consisted of the relocation of five suction points, repair/replacement of leaking pipes and
tubing, and repairs to damaged gate valves and wiring. System measurements conducted after
modifications were completed indicate the system is operating within its originally designed
specifications, as documented in Terracon’s 2020 Sub-Slab Depressurization System
Modification and Evaluation report, dated January 29, 2021. The purpose of the indoor air
sampling was to confirm the system is adequately controlling vapor intrusion into the building.

1.2 General Site Description and History

The Fleming Laboratories-RFRU Brownfields project site is a 1.562-acre parcel (Tax ID: 07-105-
122) located at 2205, 2209 and 2215 Thrift Road in Charlotte, Mecklenburg County, North
Carolina (Figure 1). The site is currently improved with an approximate 14,346 sq. ft.
warehouse building, formerly occupied by Fleming Laboratories, a former developer of feed
supplements and pharmaceuticals for livestock. The warehouse building has been partitioned
into two separate tenant spaces. The northwestern tenant space is currently occupied by
Summit Seltzer, which operates a brewery and tasting room from the suite, while the
southeastern tenant space is currently unoccupied and undergoing interior renovations for the
planned Redemption Brewing brewery and restaurant. Current site layout maps are included as
Figures 2a through 2c.

The property was admitted into the North Carolina Brownfields Program (NCBP) in 2012. Since
2014, redevelopment activities have been conducted on the site including demolition of
buildings in the southern portion of the site, on-site management of characteristically hazardous
building materials and soils, installation of a geo-fabric barrier and soil cap and the installation of
a sub-slab depressurization (SSD) system in November 2017 within the warehouse/office

building as a result of the detection of elevated levels of chlorinated compounds
(tetrachloroethylene [PCE] and trichloroethylene [TCE]) in sub-slab vapor and indoor air
samples. The indoor concentrations of previously detected compounds exceeding their non-
residential indoor air screening levels (IASLs) as well as those of chlorinated compounds
previously detected within sub-slab soil vapor are summarized within Exhibit 2 of the recorded
Brownfields Agreement. These tables have been included in Appendix A. Additional indoor air
sampling was completed in 2018 after initial installation of the SSD system. The analytical
results of the 2018 indoor air assessment are summarized in Table 1 and the associated
sample locations are shown in Figure 3.

In 2018, the property was acquired by Summit Avenue Thrift Road, LLC (PD), who planned to
renovate the on-site building for commercial tenants. According to the PD, interior building
renovations commenced in 2019 involving cuts in the floor slab and shallow trenching to install
underground utilities. Openings (cuts and trenches) within the floor slab reduced the efficiency
of the venting system temporarily until the slab was replaced. Repairs to the floor slab ultimately
improved the efficiency of the venting system. As required by the EMP, finalized in March 2019,
the SSD system was evaluated to ensure the system was functioning properly after the utility
renovations were completed. Based on the completion of repairs to the system and
measurements obtained at the facility after modifications/repairs were completed, the sub-slab
depressurization system is operating within original design constraints, as documented in
Terracon’s 2020 Sub-Slab Depressurization System Modification and Evaluation report, dated
January 29, 2021

2.0 SCOPE OF SERVICES

Terracon conducted the Brownfields Assessment activities in accordance with the Indoor Air
Sampling Work Plan, which was approved by NCDEQ via a Work Plan Approval letter, both
dated February 23, 2021. The scope of services included the collection of two indoor air
samples with one blind duplicate and one outdoor air sample. Sample locations are shown on
Figure 2a-2c. Field methods are discussed in Section 3 of this report.

Terracon’s liability to Summit Avenue Thrift Road, LLC and all relying parties unless otherwise
agreed in writing.

3.0 FIELD INVESTIGATION METHODS

Terracon conducted the field work in accordance with a health and safety plan developed for
this project. Work was performed using United States Environmental Protection Agency
(USEPA) Level D work attire consisting of a hard hat, safety vest, safety glasses, protective
gloves, and protective boots.

3.1 Indoor Air Building Survey

On March 4, 2021, prior to indoor and outdoor air sampling, Terracon completed a building
survey to document possible indoor sources of volatile organic compounds. The survey included
screening of indoor air using a parts-per-billion (ppb) capable photo-ionization detector (PID).
The results of the survey are summarized below:

Summit Seltzer Tenant Space
◼ Propane canisters utilized in outdoor heaters were observed near the front door
as well as within a storage closet in the northwestern corner of the suite.
According to the proprietor, in-use canisters are kept near the door during non-
business hours while new and empty canisters are kept within the storage room
until they are put in use or disposed of off-site.
◼ Food-grade detergents and soaps are stored and utilized within the brew lab and
a portion of the seltzer production area.
◼ PID readings ranged from less than one ppb within the seating area to 51 ppb
immediately adjacent to the bar from which seltzer is dispensed from numerous
taps. Readings in the vicinity of the soaps and detergents ranged from
approximately 7 ppb to 13 ppb.

Redemption Brewing Tenant Space
◼ Various building products were observed within this unfinished tenant space such
as: waterproofing masonry coating, acrylic/latex paints and primers, wood
finishes, latex block filler, joint compounds, fiberglass reinforced plastic
adhesives, lacquer thinners, and PVC glue/cement.
◼ One metal safety canister each of diesel fuel and gasoline were located in the
central portion of the tenant space.
◼ PID readings above the PID’s detection limit (1 ppb) were not observed within
ambient air (air within the breathing zone) within the tenant space. Elevated
readings were only observed if the PID inlet was held immediately adjacent
(within a few inches) of certain materials listed above.

Based on the PID readings and the types of materials observed (not likely to contain chlorinated
VOCs previously identified at the site), the above-listed materials were not removed prior to
sample collection. The NCDEQ DWM Indoor Air Survey Form is included in Appendix B.

3.2 Indoor / Outdoor Air Sampling

Terracon collected three indoor air samples (including a duplicate sample) and one outdoor air
sample at the site on March 5, 2021. Indoor and outdoor air sample locations are shown on
Figure 2a-2c. The indoor locations were selected to approximate the indoor air sample
locations previously obtained from within the building. The outdoor sample was placed on the
upwind side of the building, as determined the morning of sample collection. The samples were
collected in individually-certified, laboratory supplied 6-liter Summa® canisters attached to flow
controllers set for approximately 8 hours. Terracon recorded the remaining vacuum pressure
inside each of the Summa® canisters at regular intervals throughout the sampling period. Field
sample collection records for indoor and outdoor air are provided in Appendix B.

Following completion of the field activities, the Summa® canisters, along with chain-of-custody
documentation, were shipped to Con-test Analytical Laboratory (now part of the Pace Analytical
family of laboratories) in East Longmeadow, Massachusetts for analysis of a modified list of
volatile organic compounds (VOCs) by EPA Method TO-15 Low Level. Based on the prior sub-
slab soil vapor and indoor air testing conducted at the site (see Appendix A and Table 1), and
in accordance with the NCDEQ-approved Work Plan, the laboratory was instructed to analyze
the samples solely for chloroform, TCE, PCE, and the degradation products of PCE
(1,1-dichloroethane, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, and
trans-1,2-dichloroethylene).

4.0 RESULTS

The laboratory analytical reports and chain-of-custody records are provided in Appendix C.
Indoor and outdoor air sample results are summarized in Table 2.

4.1 Indoor and Outdoor Air Sample Results

Sample results for the three indoor air samples (including the duplicate) and the one outdoor air
sample collected at the site were compared to the NCDEQ DWM Indoor Air Screening Levels
(IASLs) for residential and non-residential exposure scenarios, updated January 2021.
Specifically, the most conservative IASL (A) with a target carcinogenic risk of 1.0x10-6 and a
target hazard quotient of 0.2 was used for the comparative evaluation.

In addition to the IASLs, Terracon also evaluated the indoor and outdoor sample results using
the most recent version (January 2021) version of the NCDEQ Risk Calculator. As a

conservative measure, the maximum site-wide concentrations detected for each compound
were entered into the calculator to model risk for multi-family residential (an authorized land use
under the existing Brownfields Agreement if DEQ’s prior written approval is obtained) and non-
residential (current land use) exposure scenarios. Summaries of the risk calculator evaluations
are included in Appendix D. Below is a summary of laboratory analytical results and risk
evaluation results.

Summit Seltzer Tenant Space
▪ Chloroform was detected in IA-01A (0.41 µg/m3) exceeding its Residential IASL of 0.12
µg/m3, but below its Non-Residential IASL of 0.53 µg/m3.

▪ PCE was identified at an estimated concentration (0.11 J µg/m3) an order of magnitude
below its Residential IALS of 8.3 µg/m3.

▪ Other constituents of concern (COCs), including TCE, were not detected above their
laboratory method detection limits (MDLs), all of which do not exceed their compounds’
respective Residential IASLs.

Redemption Brewing Tenant Space
▪ The sole COC identified within IA-02A or DUP-01 was PCE, which was detected at
estimated concentrations (ranging from 0.080 J to 0.099 J µg/m3) two orders of
magnitude below its Residential IASL of 8.3 µg/m3.

COCs were not identified within the outdoor air sample (OA-01) above laboratory MDLs.

The cumulative carcinogenic risk to future potential residential site occupants was calculated as
3.4x10-6 with an associated hazard index of 6.6x10-3. The cumulative carcinogenic risk to non-
residential site occupants was calculated as 7.7x10-7 with an associated hazard index of
1.6x10-3. Cumulative risk evaluations using the NCDEQ Risk Calculator indicate vapor intrusion
risks at the site are well below the acceptable threshold values under residential and non-
residential exposure scenarios for cumulative calculated carcinogenic risk and the cumulative
non-carcinogenic hazard quotient threshold value.

5.0 CONCLUSIONS AND RECOMMENDATIONS

Based on the scope of services described in this report and subject to the limitations described
herein, Terracon provides the following conclusions.

▪ Indoor air sample results indicate that the sub-slab depressurization at the site is
performing as designed and is effectively preventing an unacceptable vapor
intrusion condition from developing within the on-site building. For comparison
purposes, PCE and TCE were identified at maximum concentrations of 1.3 µg/m3 and

0.35 µg/m3, respectively, during a 2018 indoor air sampling event completed after initial
installation and prior to modification of the sub-slab depressurization system. The
identified concentrations in 2018 were not considered to pose an unacceptable risk to
building occupants. The 2021 PCE concentrations are one to two orders of magnitude
lower than detected in 2018, and TCE was not detected above its laboratory MDL in
2021.

▪ Cumulative risk evaluation using the NCDEQ Risk Calculator indicates vapor intrusion
risk at the site is well below the acceptable threshold values under residential and non-
residential exposure scenarios.

▪ Based on the 2021 indoor air sampling results and the prior sub-slab
depressurization system modification evaluation, no additional indoor air
sampling is necessary at the Fleming Laboratories-RFRU Brownfields site.
