1.0 GENERAL INFORMATION
The subject site is a warehouse located at 118 East Jones Street in Fuquay-Varina, North
Carolina (Drawing 1.1). We understand that the subject site was historically used in the
manufacture of electronics. The manufacturing ceased in the mid 1980's when Cornell-
Dubilier sold the property and ceased its operations there. Since purchased by Jones
Street, LLC, the site has been used for warehousing and small portions used for church
space. Soil and groundwater assessment activities were conducted at the subject site by
Southeastern Technical Services, PC (STS) and described in a January 7, 2016 report
titled Initial Site Assessment. The assessment identified concentrations of 1,1-
dichloroethene, tetrachloroethene (PCE), trichloroethene (TCE), bromoform and
bromomethane in groundwater at concentrations exceeding the Residential Vapor
Intrusion Groundwater Screening Level (GWSL) established by the North Carolina
Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM).
We understand that Jones Street, LLC plans to redevelop the subject site as a
conference/arts center as well as continuing church use. Jones Street, LLC plans to enter
the subject site into the North Carolina Brownfield Program (NCBP) using the Ready for
Reuse approach. Troutman Sanders is assisting Jones Street, LLC with this approach.
Troutman Sanders understands that the NCBP will require assessment of vapor intrusion
concerns at the subject site and has requested this assessment from Mid -Atlantic to
assist them with redevelopment.
2.0 SUMMARY OF FIELD ACTIVITIES
Mid -Atlantic developed a Sub -Slab and Indoor Air Sampling Work Plan (Work Plan)
dated May 17, 2017 for the subject site (Appendix A). The assessment activities
described in this report were conducted in general accordance with the Work Plan. On
June 15, 2017 a total of four sub -slab vapor sampling points (SS-2 through SS-5) were
installed at the subject site, as shown on Drawing 2.1. A sample was not collected from
SS-1 due to the presence of water in the sampling port. Three indoor air samples (IA-1
through IA-3) and an outdoor air control sample (OA-1) were also set out on June 15,
2017. The sample locations were chosen based on the rationales listed in the table
below.

To create a sub -slab sampling port, a rotary -impact drill equipped with a
decontaminated spline drill bit was utilized to drill a 5/8-inch diameter hole through the
concrete slab. The concrete slab was approximately 4 to 6 inches thick at the subject
site. The concrete slab appeared to be underlain by gravel and a brown silty clay below
the gravel. A vapor sampling probe was established using a new "Vapor Pin TM", a brass
barb fitting with a silicone sleeve that creates a seal with the concrete when inserted
using an installation/ extraction tool. The Vapor Pin was then fit with '/a -inch outer
diameter rigid -wall Teflon tubing to complete the vapor sampling probe assembly. Sub -
slab samples were collected using 1-liter stainless steel canisters at a maximum flow
rate of 200 milliliters per minute (ml/min).
The samples were collected in accordance with the NCDEQ DWM Vapor Intrusion
Guidance document (April 2014). A leak check was performed at each probe location
using a plastic shroud, helium gas and a portable helium gas detector. A plastic shroud
was placed over the sub -slab vapor probe location with the tubing of the probe exiting
the shroud through a small hole. A 3-way valve was placed on the probe termination
and connected to the sampling apparatus. Helium was released into the shroud via
tubing from the cylinder into the shroud, and a grab sample was collected by filling a
Tedlar bag using the exhaust port of the purge syringe. No leaks were detected during
the helium monitoring checks at the sub -slab sample locations.
The indoor air samples were collected using Radiello indoor air samplers which were
collected on June 22, 2017. After collection, the sub -slab soil gas and indoor air
samples were shipped to Con -Test Analytical Laboratory, Inc. (Con -Test) in East
Longmeadow, Massachusetts under proper chain of custody for analysis. The sub -slab
soil gas samples were analyzed for VOCs using standard laboratory turnaround times
in accordance with EPA Method TO-15. The indoor air samples were analyzed using
Method RAD-130 for the following compounds: vinyl chloride, 1,1-dichloroethene, trans-
1,2-dichloroethylene, cis- l,2-dichloroethylene, TCE, and PCE.
3.0 LABORATORY ANALYTICAL RESULTS
The laboratory analytical reports and chains -of -custody record for the sub -slab soil gas
and indoor air samples collected in June 2017 are provided in Appendix B and
summarized in Table 3.1 and Table 3.2, respectively. The soil gas analytical results were
initially compared to the DWM Residential and Non -Residential Vapor Intrusion Sub -Slab
Soil Gas Screening Levels (SGSLs) October 2016 Table. The indoor air analytical results
were initially compared to the DWM Residential and Non -Residential Indoor Air Screening
Level (IASL) October 2016 Table.

3.1 Risk Evaluation Methodology
May 29, 2018
Page 3
The NCDEQ has developed a tier -based Technical Guidance Document for Risk -Based
Environmental Remediation of Sites (March 2017). Tier 1, the first step in establishing risk
assessment, is to compare the individual contaminant concentrations detected at the site
to the vapor intrusion screening levels established by the DWM. The DWM establishes
soil gas and indoor air vapor intrusion screening levels for individual compounds for
residential and non-residential (industrial/commercial) exposure scenarios.
When the concentrations of contaminants detected at the site exceed the vapor intrusion
screening levels established by the DWM, the Tier 2 evaluation is required. For a Tier 2
evaluation, the cumulative risk is calculated by entering the maximum concentrations of
all contaminants detected across the site into the DEQ Risk Calculator. The DEQ Risk
Calculator determines the cancer risk sum for all carcinogens and the cumulative hazard
index for all non -carcinogens. The DWM allows a maximum cancer risk sum for all
carcinogens of 1.0E-04 and a maximum cumulative hazard index (HI) of 1.0 for all non -
carcinogens in soil gas and indoor air. The HI is the sum of the hazard quotient (HQs)
calculated for each compound detected above the reporting limit.'
The results of the Tier 1 and Tier 2 evaluations for the sub -slab soil gas and indoor air
samples are summarized in Table 3.1 and Table 3.2, respectively and discussed below.
3.2 Sub -Slab Soil Gas Sampling Results
Tier 1 (Sub -Slab Soil Gas Screening Levels)
As summarized in Table 3.1, bromoform and bromomethane were not detected in the
sub -slab soil gas samples. 1,1-dichloroehtane was detected in the soil gas sample
collected at SS-3; however, the concentration detected was below the Residential SGSL.
PCE was detected in each of the sub -slab soil gas samples, however, the concentrations
of PCE detected did not exceed the Residential SGSL. TCE was detected in each of the
samples; however, was only detected in one sample, SS-3, at a concentration
exceeding the residential SGSL. The concentration of TCE detected in SS-3 also
exceeded the Non -Residential SGSL. Additional compounds were detected above the
laboratory method detection limit (MDL) but below the Residential SGSL in each sub -
slab soil gas sample. A discussion of the risk calculations for the sub -slab samples
follows.

Tier 2 (Sub -Slab Soil Gas Risk Calculations)
The risk calculations using the maximum concentration detected in the sub -slab soil gas
are included in Table 3.1. The results of the risk calculation using the maximum
concentrations detected is discussed below.
Maximum Concentration
As summarized in Table 3.1, the residential cancer risk sum calculated using the
maximum concentrations detected was 1.6E-05, which is below the target cancer risk
sum of 1.0E-04. The residential cumulative non -cancer hazard index calculated using the
maximum concentrations detected was 3.1 E+00 which is greater than the target
cumulative non -cancer hazard index of 1.0. The non-residential cumulative non -cancer
hazard index for sample SS-3 was 2.4E-01 which is below the target cumulative non -
cancer hazard index of 1.0.
3.3 Indoor Air Sampling Results
Tier 1 (Indoor Air Screening Levels)
As summarized in Table 3.2, 1,1-dichloroethene was not detected in the indoor air
samples above the laboratory MDL. PCE was detected in each of the indoor air
samples above the laboratory MDL but below the Residential IASL. TCE was detected
in the indoor air samples at concentrations exceeding the Residential IASL but below the
Non -Residential IASL. Compounds were not detected above the laboratory MDL in the
outdoor ambient air sample (OA-1) collected from the exterior, upwind portion of the site.
A discussion of the risk calculations for indoor air samples follows.
Tier 2 (Indoor Air Risk Calculations)
The risk calculations using the maximum concentration detected in the indoor air samples
are included in Table 3.2. The results of the risk calculation using the maximum
concentrations detected is discussed below.
Maximum Concentration
As summarized in Table 3.2, the residential cancer risk sum calculated using the
maximum concentrations detected was 3.9E-06, which is below the target cancer risk
sum of 1.0E-04. The residential cumulative non -cancer hazard index calculated using the
maximum concentrations detected was 9.0E-01 which is less than the target cumulative
non -cancer hazard index of 1.0.

4.0 SUMMARY AND CONCLUSIONS
May 29, 2018
Page 5
The June 2017 Vapor Intrusion Assessment activities are summarized as follows:
• A total of four sub -slab soil gas samples and three indoor air samples were
collected from the interior of the subject site;
• Several compounds were detected in the sub -slab soil gas samples at
concentrations exceeding the laboratory MDL; however, only TCE, detected in
one sample (SS-3), was detected at a concentration exceeding the Residential
SGSL. The concentration of TCE detected in SS-3 also exceeded the Non -
Residential SGSL;
• TCE was detected in the three indoor air samples at concentrations above the
Residential IASL but below the Non-Residenital IASL;
• Using the maximum concentrations detected in the sub -slab soil gas samples the
residential cancer risk sum of 1.0E-04 was not exceeded;
• Using the maximum concentrations detected in the sub -slab soil gas samples the
residential cumulative non -cancer hazard index was 3.1 E+00, exceeding the target
cumulative non -cancer hazard index of 1.0. The non-residential cumulative non -
cancer hazard calculated using the maximum concentrations detected was 2.4E-
01, below the target cumulative non -cancer hazard index of 1.0; and
• Using the maximum concentrations detected in the indoor air samples the
residential cancer risk sum was not exceeded, nor was the residential cumulative
non -cancer hazard.
The overall objective of this investigation was to evaluate the conditions (with respect to
vapor intrusion) at the site to help facilitate the development the Fuquay-Varina Arts
Center. This data was used to determine if potential unacceptable health risks are
present at the location of the proposed Fuquay-Varina Arts Center. Based on the
results of this investigation it appears that vapor intrusion is not creating unacceptable
exposure risk for a residential exposure scenario in the subject building.

Brownfields Project Number TBD
May 17, 2017
OBJECTIVE
The objective of this Work Plan is to outline the activities proposed for conducting
sub -slab soil -gas and indoor air sampling activities at the above -referenced site.
BACKGROUND
The subject site consist of four adjacent parcels of land totaling approximately 3.69
acres and is located in Fuquay-Varina, North Carolina, southeast of the intersection
of North Main Street and East Jones Street. Parcel information is summarized in the
table below (See attached Drawing 15.1 from November 28, 2016 Phase I
Environmental Site Assessment).

Parcel A is occupied by the original warehouse which was constructed in 1946 and
is approximately 80,190 square feet. Parcel B of the subject site is occupied by a
contiguous 61,000 square foot warehouse constructed in 1957. Parcel C of the
subject site is occupied by the loading dock for the warehouse and Parcel D is
occupied by parking for the subject site as well as for the west adjacent office
building. The northwest portion of the warehouse located on Parcel A, is occupied by
the Explore Church. The northeast portion of the warehouse is vacant. The majority of
the warehouse space is utilized by the Bob Barker Company which stores large

amounts of inventory at the subject site. Many of the office spaces located throughout
the warehouse are vacant.
Land use at the subject site has been confirmed by prior reports back to 1947, when
the original warehouse, located on Parcel A, was occupied by a retail tobacco
warehouse. An addition was constructed in 1957 when Cornell- Dubilier Electronics
purchased the property. Cornell- Dubilier Electronics operated at the subject site from
1956 to 1987, manufacturing capacitors. In 1987 Bob Barker purchased the subject
site and operated a small textile/sew operation at the facility. Shortly after, the Bob
Barker Company began to operate their corporate office and distribution facility at
the subject site until 2003 when Jones Street, LLC purchased the subject site.
Soil and groundwater assessment activities were conducted at the subject site by
Southeastern Technical Services, PC (STS) and described in a January 7, 2016
report titled Initial Site Assessment. During this assessment, volatile organic
compounds (VOCs) were detected in the groundwater at the subject site (see
attached Figure 8 from January 7, 2016 Initial Site Assessment). Trichloroethylene
was detected in groundwater in concentrations exceeding screening levels
established by the North Carolina Division of Waste Management, Inactive
Hazardous Waste Branch (IHSB). This Work Plan outlines assessment activities
designed to evaluate whether presence of the VOCs in the groundwater results in a
vapor intrusion condition at the subject site.
WORK PLAN FOR SUB -SLAB SOIL -GAS AND INDOOR AIR SAMPLING
During groundwater assessment activities conducted by STS, five groundwater
monitoring wells were constructed and sampled. A total of ten different VOCs were
detected in the groundwater at the subject site. Of these ten detected compounds,
IHSB has established screening levels for five of them (1,1-dichloroethene,
tetrachloroethene, trichloroethene (TCE), bromoform and bromomethane). The
groundwater sample collected from wells MW-1 (1.06 ug/I) and MW-3 (25.5 ug/I)
exhibited concentrations of TCE that exceed IHSB's residential screening level (1.04
ug/1). The sample collected from MW-3 has a TCE concentration that also exceeds
the IHSB's non-residential screening level (4.35 ug/1).
The warehouses use three sumps equipped with pumps to manage perched water in
a portion of the warehouse (Figure 8). There is also a storm sewer junction box
located inside the warehouse at the subject site. The sumps and the sewer junction
are essentially open to the atmosphere within the warehouse. Due to the presence
of these open sumps and junction box, indoor air sampling coupled with sub -slab
sampling is included in this Work Plan.
Refer to attached Figure 8-Modified for sample locations and the table below for
sample location rationale.

Outdoor air control sample
For each sub -slab sample, a vapor pin (vapor pin is an air -tight barbed fitting) will be
installed in the floor slab for use as a sampling port. The sub -slab vapor sample will be
collected using a 1-liter "Mini-SUMMA" canister at a maximum flow rate of 200 ml/min
through the vapor pin. For quality assurance purposes, an in -field leak check will be
performed prior to sample collection using helium tracer gas, a shroud over the
sample port site and a portable helium detector. The collected sample will be analyzed
using the procedures described in TO-15.
For the indoor and outdoor air samples, Radiello 130 Chemical Desorption diffusive
samplers will be used. The samplers will be placed at each location illustrated on
Figure 8-Modified between 3 and 6 feet above the floor. The samples will remain in
place for the time required to meet IHSB residential indoor screening levels which is
anticipated to be seven days.
Each sample collected will be tested for the presence of the five VOCs previously
detected in the groundwater at the subject site and for which IHSB has established
screening levels. These compounds are 1,1-dichloroethene, tetrachloroethene,
trichloroethene, bromoform and bromomethane
The results of these assessment activities will be detailed in an assessment report.
The report will include laboratory reports, drawings, data tabulation tables, a
description of field activities and a discussion of results including data comparisons
to Residential/Non-residential Indoor Air Screening Levels. Cumulative risk
evaluation will be conducted, if warranted.
Note: In the event that the elevation of the perched water table prevents collection of
sub -slab samples, indoor air samples will be collected at all five `SS' locations and
the outdoor air location identified on Figure 8-Modified.

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
R-01 Duplicate RPD is outside of control limits. Reduced precision is anticipated for reported result.
V-20 Continuing calibration did not meet method specifications and was biased on the high side. Data validation is not
affected since sample result was "not detected" for this compound.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
Note: Air Volume field is actually the total minutes used to calculate sample volume.
For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 mL/min. The theoretical sampling rates for vinyl chloride, 1,1-dichloroethene, trans-1,2-dichloroethene, and
cis-1,2-dichloroethene are estimated using Graham's Law and are as follows: vinyl chloride = 103 mL/min, 1,1-dichloroethene = 83 mL/min,
trans-1,2-dichloroethene = 83 mL/min, cis-1,2-dichloroethene = 83 mL/min. The results for these 4 compounds are estimated values.
The results of analyses reported only relate to samples submitted to the Con -Test Analytical Laboratory for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate
carcinogenic risk or
hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 µg/m'.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated
with non-volatile chemicals. Risks are calculated for these values if indoor air
concentrations are entered and indoor air screening levels have been established,
but it should be noted that detections
of these chemicals
are likely not associated
with vapor intrusion.
