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 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. (GEM).
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 in general accordance with the referenced Work Plan and our proposal to you
dated August 28, 2018. One significant change to this Work Plan was implemented and
that change was to increase the sampling frequency from semi-annually to quarterly.
2.0 SUMMARY OF FIELD ACTIVITIES
2.1 Preliminary Site Reconnaissance
On February 19, 2019, Mid -Atlantic personnel conducted a reconnaissance visit to the
site to inspect sampling locations and place Radiello® samplers. Mid -Atlantic personnel
were accompanied by the site property manager, Lowell Lovell and Marian Kozek
(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 on February
19, 2019 and are included in Appendix A. No breaches were identified.

Mid -Atlantic's reconnaissance included an inspection of the HVAC fresh air system for
the southeast corner space (Web -Don). The inspection confirmed the air handing units
(AHU) controls were in the same location as previously set (estimated to be 30% fresh
air make up). The controls for these units are located above the ceiling and are labelled
with instructions prohibiting the disturbance of the controls.
2.2 Initial and Follow Up Air Sample Collection
Initial air sampling (February 19-26, 2019) was accomplished using Radiello® samples.
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 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.
2.2.1 Radiello® Seven -Day Air Sample Collection
On February 19, 2019, 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 Habitat 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 February 26, 2019. 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 tetrachloroethene (PCE), trichloroethene
(TCE), 1,1-dichloroethene, trans- 1,2-dichloroethene, cis-1,2-dichloroethene and vinyl
chloride in accordance with EPA Method Rad 130.

Based on the results of the initial sampling (February 19-26, 2019), follow up sampling
using Radiellos® and Summa canisters was conducted in the GEM space (see Section
4.0 for details). Three additional indoor air (IA-107RR, IA-119RR and IA-120RR)
samples and one outdoor sample (OA-103RR) were collected over the period of March
15 to March 22, 2019. These Radiello® cartridges were also analyzed for
tetrachloroethene (PCE), tichloroethene (TCE), 1, 1 -dichloroethene, trans-1,2-
dichloroethene, cis-1,2-dichloroethene and vinyl chloride in accordance with EPA
Method Rad 130.
2.2.2 Summa Canister Eight -Hour Air Sample Collection
Follow up sampling (March 15 to 22, 2019) was also conducted using Summa canisters
at three indoor air sample locations (IA-107SR, IA-119SR, and IA-120SR) in the GEM
space. These samples were collected, along with outdoor air sample OA-103SR,
concurrently with the follow up Radiello® samples. These 8-hour samples were
collected in order to provide indoor air quality data rapidly and to provide a comparison
between the different sampling methodologies. They were deployed in the morning of
March 15, 2019 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.
3.0 LABORATORY ANALYTICAL RESULTS
The laboratory analytical reports and chain -of -custody records for the Radiello® air
samples collected from February 19 to February 26, 2019 (initial sampling) are provided in
Appendix B and summarized in Table 3.1. The results of the Radiello® and Summa
canister collected samples collected from March 15 to March 22, 2019 (follow up sampling)
from the GEM space are summarized in Table 3.2 and included in Appendix C. Both the
initial and follow up sampling 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.
Mid Atlantic

May 3, 2019
Page 4
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 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 indoor air exposure pathway is summarized in Table 3.1 and Table
4.1, and are discussed below.
3.2 Indoor Air Screening Levels (Tier 1)
As summarized in Table 3.1, trichloroethene was detected above the laboratory MDL in 7
of the 10 indoor air Radiello® samples; the exceptions were IA-103R, IA-117R, and IA-
118R. TCE was not detected above the laboratory MDL in OA-102R. Seven of the indoor
air samples exhibited levels in excess of the NCDEQ Non -Residential Indoor Air Screening
Levels (IASLs). These included IA-106R, IA-107R, IA-110R, IA-113R, IA-114R, IA-115R,
and IA-116R.
Tetrachloroethene 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.
3.3 Indoor Air Risk Calculations (Tier 2)
As summarized in Table 3.1, 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 any
of the samples. However, the Non -Residential cumulative non -carcinogenic hazard index
calculated for the air samples collected at the site showed one sample (IA-107R in the
GEM space) exceeding the target non -cancer hazard index of 1.0E+00 (1.7E+0.0). In

addition, this sample exceeded the TCE sensitive population short term exposure limit of 9
ug/m3.
4.0 REMEDIAL ACTIONS AND FOLLOW UP TESTING
North Carolina Department of Environmental Quality considers TCE a `short term'
exposure contaminant of concern due to its potential for adverse health effects to
pregnant women in their first trimester. Under NCDEQ guidance, women between the
ages of 15 and 50 are considered a population sensitive to the exposure to TCE.
Trichloroethene was detected at 14 ug/m3° which is above the short term exposure limit
of 9 ug/ m3 in the sample collected from the GEM space.
On March 8, 2019, upon determining the sample collected from GEM space exceeded
the target non -cancer hazard index of 1.0E+00 and the TCE sensitive population short
term exposure limit of 9 ug/m3, the following activities were conducted:
• March 8, 2019 GEM was notified of the issue and overhead doors opened to
temporarily increase ventilation in the space. GEM personnel also indicated that
their space is not regularly occupied by individuals meeting the criteria of the
sensitive population. It was later determined that one part time employee working as
a bookkeeper met the definition of sensitive population.
• March 12, 2019 NCDEQ was notified of the TCE detection above acceptable levels
and of the actions taken to increase ventilation in the GEM space.
• March 12, 2019 permanent modifications to the ventilation system were installed.
These included the activation of an intake fan and the installation of two exhaust
vents. The operation of permanent ventilation in the GEM space is access
controlled.
• March 15, 2019 follow up 8-hour Summa air samples were collected and Radiellos®
deployed at the same three locations in the GEM space to assess indoor air quality
after the ventilation modifications were implemented. These samples were collected
with the overhead door closed (except when necessary to move materials into and
out of the GEM space). One outdoor air sample was also collected.
• March 21, 2019 a NCDEQ toxicologist and the GEM bookkeeper discussed the
potential health risks associated with TCE.

4.1 GEM Indoor Air Screening Levels (Tier 1)1
As summarized in Table 4.1, after the ventilation system improvements were implemented,
but the overhead door remained closed, trichloroethene was detected above the laboratory
MDL in one Radiello® sample collected in the GEM space. Trichlorethene was not
detected in any of the Summa-collected samples. The TCE concentration detected in the
Radiello® sample is above the NCDEQ Non -Residential IASL. Tetrachloethene was
detected in each sample (Radiello® and Summa) but at concentrations below NCDEQ
Non -Residential IASLs. Low concentrations of three other chlorinated compounds were
also detected.
4.2 GEM Indoor Air Risk Calculations (Tier 2)2
As summarized in Table 4.1, the Non -Residential cancer risk sum calculated for the air
samples collected at the site after implementation of the ventilation system improvements
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.
5.0 SUMMARY AND CONCLUSIONS
During the February 2019 indoor air quality monitoring activities, a total of 10 indoor air
samples were collected from the interior of the building on the subject site. In addition,
one Radiello® outdoor air sample was collected in the vicinity of the southeast corner of
the building. Due to an exceedance of the target Hazard Index in one sample collected
from the GEM space, ventilation system improvements were implemented and follow up
sampling was conducted. Based on the actions taken and the data collected during this
investigation, we offer the following observations for the Non -Residential scenario.
The GEM space is used for cabinet construction. For these activities petroleum -based adhesives,
solvents, paints and stains are extensively used. Petroleum products are not present in the groundwater
at the site. Chlorinated solvents are present in the groundwater. Therefore, the Tier 1 analysis was
conducted for chlorinated compounds only. Petroleum compounds were not included in the analysis.

• No breaches in the floor slab in the warehouse were observed.
• The AHUs in the Web -Don office area were unchanged and set at 30% fresh air
prior to the sampling activities occurring.
• The indoor samples collected from the Lottery Office space were non -detect for
PCE and TCE.
• All of the indoor air samples collected in the `warehouse' portion of the building
contained detectable concentrations of PCE and 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.
• Seven 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.
• One of the initial indoor air samples, collected from the GEM space, exceeded
the Non -Residential cumulative risk HI of 1.0.
• North Carolina Department of Environmental Quality considers TCE a `short
term' exposure contaminant of concern due to its potential for adverse health
effects to pregnant women in their first trimester. Trichloroethene was detected in
one sample collected in the warehouse area (GEM space) at a concentration
exceeding the Non -Residential `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.
• GEM and NCDEQ personnel were notified of the exceedance and the one part-
time occupant of the GEM space meeting the sensitive population criterion was
informed of the health risks associated with TCE.
• Immediate actions were taken to ventilate the GEM space and permanent
improvements to the ventilation system were implemented within four days of
identifying the issue.
• Both short term (Summa) and longer term (Radiello®) samples were collected
immediately following the ventilation system upgrades. These data show indoor
air quality in the GEM space meets acceptable risk criteria (HI<1).
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. However, to achieve this condition supplemental ventilation is required in the
Web -Don and GEM spaces.

Comparison of the data collected during in February 2019 described in this report to
previous indoor air quality data collected at the subject site in November 2018 shows that,
with the exception of the GEM space, the results are consistent. The GEM space is
equipped with a large overhead door that was often open during the warmer November
2018 sample event. During the cooler weather of February 2019 the overhead door was
closed much more often. The follow up (March 15-22, 2019) indoor testing was conducted
with the overhead door closed and the new ventilation system operational. The data
indicates the ventilation system has abated the problem.
The data collected from the two sample locations in the Lottery offices show no detections
of PCE or TCE. These data are similar to historical data from the Lottery office area. These
data suggest that continued monitoring in the Lottery office may not be 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 and ventilation is required
in the Web -Don and GEM spaces.
The results for the three samples collected concurrently using Radiellos® and Summa
canisters during the follow up sampling in the GEM space show comparable results with
the Radiellos® typically slightly higher concentrations than the Summa collected samples.
The only TCE detection during this sampling was identified in a Radiello® sample. 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.
Recommendation
Mid -Atlantic recommends that the indoor air monitoring continue on a quarterly schedule.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method Radiello RAD-130 - The sampling rates for trichloroethene and tetrachloroethene are as follows: trichloroethene = 69 mL/min,
tetrachloroethene = 59 tuUmin. 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 mUmin, 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.
