Brownfields Vapor Assessment Report Building 3 – Central Rite Aid Brownfields Site Charlotte, North Carolina H&H Job ATL-007
1.0 Introduction
On behalf of Camp Landowner, LP c/o Camp North End (CNE), Hart & Hickman, PC (H&H) has
prepared this Brownfields Vapor Assessment Report to describe additional vapor assessment
activities completed within the central portion of Building 3 located on the Rite Aid Brownfields
property located at 1730 Statesville Avenue (also listed at 201 Camp Road and 701 Keswick Avenue)
in Charlotte, Mecklenburg County, North Carolina (Site or subject Site). Building 3 is located in the
southern-central portion of the Camp North End (CNE) mixed-use redevelopment project. Note, the
Building 3 identification number referred to in this report is the building number designated by the
CNE redevelopment and differs from other building number notations utilized by the US Army Corps
of Engineers (Corps) as part of ongoing assessment activities currently be conducted under a Formerly
Used Defense Sites (FUDS) contract. A Site location map is provided as Figure 1 and a Sample
Location Map is provided as Figure 2.

The Rite Aid Brownfields Site is approximately 47.87 acres and is comprised of three contiguous
parcels of land (Mecklenburg PIN #s 07903102, 07903105, and 07903103). The Site entered into a
Brownfields Agreement with the North Carolina Department of Environmental Quality (DEQ)
Brownfields Program (Brownfields Project #20050-16-060) in October 2017. Soil and groundwater
contamination consisting primarily of volatile organic compounds (VOCs) including chlorinated
solvents and metals due to historical operations and activities. As noted above, the Corps on behalf
of the US Department of Defense (DOD) is working with DEQ to address impacts release to historical
operations conducted at the Site including manufacturing of Model T Ford automobiles, a storage
depot for the US Government, and for production of Hercules missiles for the military.

Building 3 is currently a warehouse constructed with brick and concrete block walls on a raised
concrete foundation. The northern portion of the warehouse is currently occupied by a restaurant
(Unit B3B1) and brewery (Unit B3B2) and the central (B3B3 and B3B4) and southern (B3B5 and

B3B6) portions of the warehouse are currently vacant. During Site redevelopment activities, a
roadway connection (referred to “Connection G”) is proposed that will separate the central and the
southern portions of Building 3 creating two separate buildings. The central portion of Building 3 is
proposed for a 22,869-square ft multi-family redevelopment “U-shaped” structure. Specific details
for the multi-family structure are currently being prepared. The southern portion of Building 3 is
proposed for future commercial use. It is not anticipated that there will be a connected HVAC system
between the multi-family and the other commercial structures. A proposed development plan for
Building 3 is provided as Appendix A.

The vapor assessment activities described in the following sections were performed in accordance
with the Work Plan Additional Vapor Assessment – Revision 1 (Work Plan), dated August 11, 2021,
and approved by DEQ on August 12, 2021. Background information from a previous sub-slab soil
gas assessment activity conducted during initial Brownfield assessment activities is summarized
below in Section 2.0 and the recent assessment activities are summarized in Section 3.0.

2.0 Previous Assessment Activities
Background Information
H&H conducted initial Brownfield assessment activities at the Site, which consisted of sub-slab soil
vapor (SSV) sampling activities in 2016, including assessment at Building 3. The SSV sampling
results were summarized in the H&H Phase I and II Environmental Site Assessment report dated
August 16, 2016. A summary of the SSV sampling results for Building 3 is described below and
excerpts from the previous sampling are provided in the Work Plan.

During initial Brownfield assessment activities conducted in 2016, H&H conducted sub-slab
sampling activities and identified VOCs in the central (SSV-7) and northern (SSV-8) portions of
Building 3 at concentrations below DEQ Residential and Non-residential Vapor Intrusion Screening
Levels (VISLs). The VOC trichloroethylene (TCE) was detected in the sub-slab sample SSV-7 at a
concentration of 2.1 micrograms per cubic meter (µg/m³), which is below the Residential and Non-
residential VISLs of 13.9 and 175 µg/m³, respectively. TCE was not detected above laboratory
detection limits in the SSV-8 sub-slab sample. Based on the results of the SSV sampling, H&H did
not conduct indoor air (IA) sampling activities in Building 3 in June 2016. The source of the TCE
contamination appears to be a TCE plume in groundwater located northeast of Building 3, near
Building 2, which appears to flow away from Building 3 in a north to northwesterly direction. A
vapor intrusion mitigation system (VIMS) is planned to be installed in the northern portion of the
adjacent Building 2 (Building 2 – North) where VOCs have been detected in groundwater, sub-slab
vapor, and indoor air samples.

Based on the VOC results in sub-slab vapor samples within the central and northern portion of
Building 3, DEQ determined that vapor mitigation controls were not warranted in Building 3.
However, DEQ requested further assessment of the central portion of Building 3 prior to development
of proposed multi-family residential redevelopment due to the duration of time since this portion of
the building was last assessed (2016), and the proposed redevelopment of the central portion of the
Site for residential use. A summary of the completed activities for the additional vapor assessment is
presented below in Section 3.0.

3.0 Vapor Assessment Activities
3.1 Sub-slab Vapor Point Installation Activities
In order to further evaluate the potential for vapor intrusion associated with the proposed multi-
family use in the central portion of Building 3, on August 25, 2021, H&H installed and sampled
six (6) permanent sub-slab vapor sampling points (B3-SSVP-1 through B3-SSVP-6) advanced in
the footprint of the proposed multi-family residential structure. The sample locations are depicted
on Figure 2. The actual sub-slab sampling locations were measured in the field using the existing
building exterior walls.

The sub-slab vapor sample locations were installed and sampled in general accordance with the
DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance and the Work Plan.
Briefly, the sub-slab vapor points were installed by utilizing a hammer drill and 1½-inch diameter
drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾ inches below
the surface. A drill guide was then placed in the pilot hole, and a 5/8-inch diameter drill bit will
be utilized to advance the boring through the concrete slab. Following concrete borehole
advancement, loose concrete cuttings were removed from the boring using a bottlebrush and high
efficiency particulate air (HEPA) vacuum. A Cox-Colvin Vapor Pin™ (vapor pin) assembly
(stainless steel sampling point and silicone sleeve) were seated in the borehole using an
installation/extraction tool and hammer. The vapor pins were installed as flush-mount sample
points capable of being secured with a stainless-steel cover that screws onto the sampling point
and is seated within the pilot hole annulus.

3.2 Sub-Slab Vapor and Soil Gas Sampling Activities Prior to sampling the sub-slab and soil-gas vapor monitoring points, a leak check was conducted at
each location by constructing a shroud over the entire sampling train and flooding the air within the
shroud with helium gas. Using an air pump, a sample was collected from the gas in the shroud into a
Tedlar® bag and analyzed for helium concentrations using a helium gas detector. Vapor from the
monitoring points was purged and sampled outside of the shroud into a separate Tedlar® bag and
analyzed using the helium gas detector. The leak checks indicated that the helium concentrations

through the sample train were less than 10% of the concentration measured within the shroud
indicating a successful leak check for each sample.

Following the successful field leak check, the sub-slab vapor samples were collected into approximate
one-liter Summa canisters for laboratory analysis by connecting the Teflon® sample tubing to an
airflow regulator using a brass nut and ferrule assembly to create an airtight seal. The airflow
regulator was calibrated by the laboratory to allow the Summa canisters to fill slowly at a rate not
greater than 200 milliliters per minute.

In addition to the helium leak tests, shut-in leak tests were performed on each Summa canister and
sampling train prior to sampling to ensure no leaks were present through the regulator or canister
connections. Upon completion of sample collection, the air flow regulator was removed from the
Summa canister and the samples were submitted to Waypoint Analytical, LLC (Waypoint) under
standard chain of custody protocols for analysis of full-list VOCs by EPA Method TO-15. Upon
receipt of the samples, the laboratory recorded the final received vacuum pressure for each Summa
canister. The vacuum pressure in each Summa canister as measured in the field and laboratory upon
completion of the sampling event was between five and seven inches of mercury (inHg). The
laboratory and field starting and ending vacuum concentrations are listed the field sampling logs in
Appendix B and on the laboratory chain-of-custody in Appendix C.
3.3 Quality Assurance/Quality Control
For field and laboratory quality assurance/quality control (QA/QC) purposes, H&H collected one
duplicate sub-slab sample to satisfy DEQ Brownfields minimum sample frequency of 1 duplicate per
20 samples per media and method. The duplicate sample (B3-SSVP-DUP-1) was collected using a
laboratory supplied “T-sampler” from the B3-SSVP-4 parent sample location and was analyzed for
the same compounds as the parent sample. In addition, H&H requested a Level II QA/QC data
package from the laboratory and the laboratory reported values to the laboratory-specified method
detection limits using J-flags.

4.0 Vapor Assessment Results The vapor assessment results from the central portion of Building 3 sub-slab vapor samples (B3-
SSVP-1 through B3-SSVP-6) are summarized on Table 1 and the laboratory analytical report is
included as Appendix C. The sample results were compared to the DEQ DWM Residential and Non-
residential Soil-gas Screening Levels (SGSLs).

The results indicate that several low-level VOCs were detected above laboratory reporting limits in
each of the sub-slab vapor samples, but below the respective DWM Residential and Non-residential
SGSLs. The site VOC contaminant of concern, TCE, was not detected above laboratory method
detection limits in any of the sub-slab samples. However, the VOC tetrachloroethene (PCE) was
detected in each of the sub-slab samples ranging from 5.66 µg/m3 in B3-SSVP-1 to 210 µg/m3/211
µg/m3 in B3-SSVP-4/B3-SSVP-DUP-1. These PCE concentrations are all below the Residential and
Non-residential SGSLs of 280 µg/m³ and 3,500 µg/m³, respectively.

To further assesses the sub-slab results, H&H calculated risk for the detected VOC concentrations.
H&H utilized data collected from B3-SSVP-1 through B3-SSVP-6 using the DWM Risk Calculators
dated June 2021. A combined “worse-case” residential and non-residential risk calculation was
performed by using the highest detected concentration of each constituent from all of the samples.
Risk calculator summary pages are included as Appendix D.

The results of the cumulative risk calculations for the recent vapor assessment event indicate that the
calculated “worse-case” cumulative potential carcinogenic and non-carcinogenic risks for the sub-
slab soil gas samples are within the acceptable risk range of 1 x10-4 to 1 x 10-6 and the calculated
hazardous index (HI) are less than 1 for both residential and non-residential use. The calculated
residential use carcinogenic risk was 2.3 x 10-6 and the HI was 0.18, and the non-residential calculated
carcinogenic risk was 1.7 x 10-7 and the HI was 0.014. Therefore, the results of the vapor assessment
do not indicate a significant risk exposure within the central portion of Building 3 to future occupants
and non-residential workers within the proposed residential building.

5.0 Summary and Recommendations
H&H has completed soil gas point installation and sub-slab vapor sampling in the central portion of
Building 3 at the Rite Aid Brownfields Property. A brief summary of the sampling results is provided
below.

• H&H installed and sampled six (6) permanent sub-slab vapor sampling points (B3-SSVP-1
through B3-SSVP-6) on August 25, 2021.
• Results of the soil gas assessment activities did not identify VOC compounds at
concentrations above DWM Residential or Non-residential SGSLS.
• TCE was not detected above laboratory method detection limits in any of the samples. The
VOC PCE was detected at a concentration above laboratory method detection limit in each
sub-slab sample, but at concentrations below the DWM Residential and Non-residential
SGSLs.
• The results of the cumulative risk calculations for the recent vapor assessment event indicate
that the calculated “worse-case” cumulative potential carcinogenic and non-carcinogenic risks
for the soil gas samples are within the acceptable risk range of 1 x 10-4 to 1 x 10-6 and the
calculated HI are less than 1 for both residential and non-residential use.
Based on the vapor assessment results in the central portion of Building 3, there does not appear to be
a significant risk exposure to future workers nor to future occupants within the proposed multi-family
residential development.
