1.0 GENERAL INFORMATION AND BACKGROUND
The subject site consists of one parcel totaling approximately 32.33 acres located along
Capital Boulevard and Westinghouse Boulevard in Raleigh, Wake County, North Carolina
(Drawing 1.1 and Drawing 1.2). The subject site is currently occupied by one
approximately 546,791-square foot structure and associated parking lots. The structure is
occupied by six tenants, with some of the spaces being unoccupied at the time of these
activities. The current tenants include the North Carolina Education Lottery (Lottery),
Inventory Management Incorporated (IMI), Reico Kitchen and Bath (Reico), Web -Don,
Inc., Habitat for Humanity of Wake County (Habitat), and Great Escape Millwork, Inc.
(Great Escape).
During performance of several investigations at the site, it was determined that past
operations have had an adverse environmental impact on the site. More specifically, it
was determined that a vapor intrusion condition appears to exist at the site. SVC 2728
Capital Partners, LLC (SVC) submitted an application to the North Carolina Brownfields
Program (NCBP) on April 3, 2018 and received their Letter of Eligibility on June 1, 2018.
The project is currently working its way through the brownfield process.
Since vapor intrusion conditions are known to exist at the site, an Indoor Air Quality
Monitoring Work Plan (Work Plan) dated October 4, 2018 was developed by Mid -Atlantic
and the NCBP. At your request, Mid -Atlantic has conducted indoor air quality monitoring
services as outlined in the referenced Work Plan and our proposal to you dated August
28, 2018.
2.0 SUMMARY OF FIELD ACTIVITIES
2.1 Preliminary Site Reconnaissance
On October 15, 2018, Mid -Atlantic personnel conducted a reconnaissance visit to the
site to identify the selected locations for collection of the indoor air samples. Mid -
Atlantic personnel were accompanied by the site property manager, Mr. Lowell Lovell
and Mr. Ira Seamster (facilities manager for the Lottery space). During this visit, Mid -
Atlantic personnel completed the Indoor Air Building Survey and Sampling Form as
presented in the North Carolina Department of Environmental Quality (NCDEQ)
Division of Waste Management's (DWM) Vapor Intrusion Guidance Document (March
2018). A copy of this form is included in Appendix A. The sample locations are
identified on Drawing 2.1 and Table 2.1 presents the tenant space occupants for each
of the indoor air samples.
Additionally, as per the activities outlined in the referenced Work Plan during the site
reconnaissance Mid -Atlantic observed the floor slab of the warehouse spaces for
indications that it had been breached. These observations were recorded and are
presented in Appendix A.

Also included in Mid -Atlantic's reconnaissance was a request for Mr. Lowell Lovell to
conduct an inspection of HVAC fresh air system for the southeast corner space (Web -
Don) which was intended to confirm that a minimum of 30% fresh air is maintained. Mr.
Lovell requested that an independent contractor, Piedmont Service Group, perform this
inspection. Piedmont Service Group conducted a site visit on October 29, 2018 (prior to
the sampling activities). Their report states that the economizers in the air handling
units (AHUs) were set at 15-20% but were adjusted to 30% per Mr. Lovell's request.
This report is included in Appendix B.
2.2 Air Sample Collection
Air sampling was accomplished using two types of methods; Radiello® samples and
8-Hour Summa canisters. The indoor Radiello® air samplers were placed in locations
throughout the building including areas where previous assessment findings identified
elevated contaminants in sub -slab soil gas. All Radiello® samplers were exposed for
approximately seven days. The eight -hour Summa air samples were collected using
individually certified, 6-liter, stainless steel, Summa canisters at a maximum flow rate of
8-10 milliliters per minute (ml/min). The samplers were placed in the breathing zone (3
to 6 feet above the floor) for seated and standing building occupants. The air sample
locations are illustrated on Drawing 2.1 and the respective spaces are detailed in Table
2.1. The sample location identifiers were modified with a suffix to identify the type of
sample collected; an "R" identifies the Radiello® samples and an "S" identifies the
Summa canister samples.
2.2.1 Radiello® Seven -Day Air Sample Collection
On October 31, 2018, a total of 11 Radiello® air samplers were placed at the subject
site; 10 were placed to collect indoor air samples (IA-103R, IA-106R, IA-107R, IA-11OR,
and IA-113R through IA-118R) and one was placed to collect an air sample outside the
building (OA-102R).
The Radiello® air sampler (OA-102R) was placed outside the south side of the building
near the southeast corner (between the Great Escape and Web -Don spaces). The
outdoor air sample was collected to provide a comparison with the indoor air quality
results.
The Radiello® diffusive air samplers were deployed in accordance with the
manufacturer instructions and the NCDEQ DWM Vapor Intrusion Guidance document
(March 2018). The sampling cartridge was removed from its plastic sleeve and placed
into the diffuser, the end of the cartridge was positioned in the seat, and the diffuser
was then screwed into the supporting plate. The cartridges were collected seven days
later on November 7, 2018. The diffusers were unscrewed from the plates, the

sampling cartridges replaced into their original tubes, the tubes properly labeled, and
placed back into their corresponding plastic bags.
After collection, the Radiello® air samplers were shipped to Con -test Analytical
Laboratory in East Longmeadow, Massachusetts under proper chain of custody for
analysis. The cartridges were analyzed for tetrachloroethylene (PCE) and
trichloroethylene (TCE) in accordance with EPA Method Rad 130.
2.2.2 Summa Canister Eight -Hour Air Sample Collection
Five indoor air sample locations (IA-103S, IA-11OS, and IA-116S through IA-118S)
were selected for the collection of a concurrent 8-hour indoor sample collected using
Summa canisters. These 8-hour samples were collected in order to provide a
comparison between the different sampling methodologies. They were deployed in the
morning and were collected approximately eight hours later. These sample locations
are also illustrated on Drawing 2.1.
After collection, the air samples were shipped to Con -test Analytical Laboratory in East
Longmeadow, Massachusetts under proper chain of custody for analysis. The air
samples were analyzed for VOCs in accordance with EPA Method TO-15 for
tetrachloroethylene and trichloroethylene.
3.0 LABORATORY ANALYTICAL RESULTS
The laboratory analytical reports and chain -of -custody records for the air samples (both
Radiello® and 8-hour samples) collected on October 31 through November 7, 2018 are
provided in Appendix C and summarized in Table 3.1 (Radeillo® samples) and Table 3.2
(Summa samples). The indoor air analytical results were compared to the DWM Non -
Residential Indoor Air Screening Levels (IASLs) February 2018 Table.
3.1 Risk Evaluation Methodology
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 and indoor air screening levels established by the DWM. The DWM
establishes screening levels for individual compounds for Non -Residential
(industrial/commercial) exposure scenarios.
When the concentrations of contaminants detected at the site exceed the screening
levels for all pathways established by the DWM, the Tier 2 evaluation is required. For a
Tier 2 evaluation, the cumulative risk is calculated by entering the maximum
".11 Mid Atlantic

concentrations of all contaminants detected at each established exposure unit (EU) into
the DEQ Risk Calculator (October 2017). An EU is a defined area of a site represented by
a specific set of land use(s), receptors, contaminant concentrations, and exposure
pathways. Due to the size of the onsite structure, the distance between sample locations
and the potential for the future use of the building areas to change, exposure units were
not used during this assessment and risk calculations were performed on concentrations
detected at each sample location.
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 each exposure pathway. The HI is the sum of the hazard
quotient (HQs) calculated for each compound detected above the reporting limit. The
NCDEQ risk calculations for the subject site are included in Appendix D. The results of
the Tier 1 and Tier 2 evaluations for each exposure pathway are summarized in Table 3.1
and Table 3.2, and are discussed below.
3.2 Indoor Air Screening Levels (Tier 1)
As summarized in Table 3.1, trichloroethylene was detected above the laboratory MDL in
6 of the 10 indoor air Radiello® samples; the exceptions were IA-103R, IA-107R, IA-
117R, and IA-118R. TCE was not detected above the laboratory MDL in OA-102R. Five
of the indoor air samples exhibited levels in excess of the NCDEQ Non -Residential Indoor
Air Screening Levels (IASLs). These included IA-106R, IA-11 OR, IA-113R, IA-115R, and
IA-116R.
Tetrachloroethylene was detected above the laboratory MDL in 8 of the 10 indoor air
Radiello® samples; the exceptions were IA-117R and IA-118R. PCE was not detected
above the laboratory MDL in OA-102R. None of the indoor air samples exhibited levels in
excess of the NCDEQ IASLs.
As summarized in Table 3.2, trichloroethylene was detected above the laboratory MDL in
1 of the 5 indoor air Summa canister samples, this sample was IA-116S. TCE was not
detected above the Non -Residential IASL for this sample.
Tetrachloroethylene was detected above the laboratory MDL in 4 of the 5 indoor air
Summa canister samples, the exception was IA-11OS. PCE was not detected above the
Non -Residential IASL for these samples.

3.3 Indoor Air Risk Calculations (Tier 2)
Non -Residential Risk Calculations
As summarized in Table 3.1 and Table 3.2, the Non -Residential cancer risk sum
calculated for the air samples collected at the site did not exceed the target cancer risk
sum of 1.0E-04 for either the Radiello® samples or the 8-hour Summa canister samples.
The Non -Residential cumulative non -carcinogenic hazard index calculated for the air
samples collected at the site did not exceed the target non -cancer hazard index of
1.0E+00 at the sampling locations for either the Radiello® samples or the 8-hour Summa
canister samples.
4.0 SUMMARY AND CONCLUSIONS
During the November 2018 indoor air quality monitoring activities, a total of 15 indoor
air (both Radiello® and 8-hour Summa canister) samples were collected from the
interior of the building on the subject site. In addition, one Radiello® outdoor air
samples was collected in the vicinity of the southeast corner of the building. Based on
the data collected this investigation, we offer the following observations for the Non -
Residential scenario.
Summary
• No breaches in the floor slab in the warehouse were observed.
• The AHUs in the Web -Don office area were set at 30% fresh air prior to the
sampling activities occurring.
• All of the indoor air samples contained detectable concentrations of PCE and/or
TCE.
• The outdoor air sample did not contain detectable concentrations of PCE or
TCE.
• The PCE concentrations in the indoor air samples did not exceed the Non -
Residential IASL.
• Five indoor air samples exhibited TCE in concentrations exceeding the Non -
Residential IASL.
• None of the indoor air samples exceeded the Non -Residential target cancer risk
sum of 1.0E-04.
• None of the indoor air samples exceeded the Non -Residential cumulative risk HI
of 1.0.
• Trichloroethylene is a `short term' exposure contaminant of concern due to its
potential for adverse health effects to pregnant women in their first trimester.
Trichloroethylene was detected in six of the eight samples collected in the
warehouse area. However, none of the samples exceeded the Non -Residential
".11 Mid Atlantic

`short term limit, of 9 ug/m3 (the concentration where NCDEQ requires immediate
actions) which equates to the Non -Residential cumulative HI of 1.0 for TCE
alone. Trichloroethylene was not detected in the Lottery office area.
Conclusions
The data collected during this assessment indicate that vapor intrusion is occurring at the
subject site, but not at a rate that results in an unacceptable risk under the Non -
Residential use scenario.
Comparison of data collected during in November 2018 described in this report to
previous indoor air quality data collected at the subject site (Vapor Intrusion Assessment
Report — Phase 11, December 5, 2017 and Vapor Intrusion Assessment Resampling at
Location IA-3, February 12, 2018) shows that the results are consistent.
The data collected from the two sample locations in the Lottery offices show no
detections of trichloroethylene for either test method (Radiello® or the 8-hour Summa
canister). In these same samples tetrachloroethylene was not detected in the Radiello®-
tested samples but was detected in the 8-hour Summa samples. However, the detected
concentrations are an order of magnitude below the IASL for tetrachloroethylene. These
data suggest that continued monitoring in the Lottery office is not warranted.
The data collected from the warehouse portions of the building (south of the Lottery
offices) suggests that periodic indoor air quality monitoring is warranted.
Comparing the results for the five samples collected concurrently using Radiellos® and
Summa canisters show essentially equivalent results for three of the five samples tested
for PCE. One of the five samples tested for PCE was higher using the Summa method,
while the other showed the Radiello® result to be higher. For TCE, two of the five
samples were essentially equivalent. The Radiello® samples exhibited higher readings
than the Summa canisters for the other three samples tested for the presence of TCE.
Both methods have similar detection limits for PCE and TCE. This subjective evaluation
suggests that either sample collection method is satisfactory. Similar results were
observed during previous assessments conducted at the subject site. It appears that the
sample collection method to use at this site can be determined based on factors other
than representativeness of the samples collected.
