Brownfields Assessment Report
Hokes Street Passage Home
Raleigh, North Carolina
Brownfields Project No. 21007-17-092
H&H Job No. APT-001
1.0 Introduction
On behalf of Passage Home Inc. and their affiliate, Hoke Street PH Redevelopment, LLC (Passage
Home), Hart & Hickman, PC (H&H) conducted Brownfields assessment activities at the Hoke
Street Passage Home Brownfields Property (Brownfields Project No. 21007-17-092) located at
500 and 506 Hoke Street, and 1402 and 1412 Garner Road in Raleigh, Wake County, North
Carolina (subject Site, Site, or Brownfields Property). The Site consists of four contiguous parcels
(Wake County Parcel Identification Nos. [PINS] 1703828886, 1703920846, 1703922815, and
1703920658) that total approximately 3.95 acres. The 500 Hoke Street parcel is developed with
an approximately 14,500-square-foot (sq ft) warehouse building constructed in 1948. The 1402
Garner Road parcel formerly operated as a petroleum station from the 1930s until the 1980s, and
is currently developed with an approximately 2,500 sq ft convenience store building constructed
in 1963, and an approximately 1,800 sq ft vacant automotive repair building constructed in 1945.
The remainder of the Site is undeveloped or is improved with paved and gravel parking areas.
Hoke Street PH Redevelopment, LLC purchased the 500 and 506 Hoke Street and 1412 Garner
Road parcels on January 30, 2017, from McKnitt and Associates LLC, which had owned the
property since the 1960s. On January 6, 2020, the North Carolina Department of Environmental
Quality (DEQ) and Hoke Street PH Redevelopment, LLC entered into a Brownfields Agreement
(BFA) for the 500 and 506 Hoke Street, and 1412 Garner Road parcels.
On August 8, 2022, Passage Home Inc. purchased the 1402 Garner Road parcel from the Moore
family, which had owned the property since the early 1960s. Prior to the purchase, on July 15,
2022, Passage Home submitted a Brownfields Property Application to add the 1402 Garner Road
parcel to the existing Brownfields Property. The 1402 Garner Road parcel received eligibility into
the DEQ Brownfields Program via an Amended Letter of Eligibility dated December 12, 2022.

Proposed redevelopment plans for the Site include combining the four parcels, razing the existing
buildings, and minimal ground disturbance for the construction of a four-story senior living
apartment building with associated parking areas, access drives, and stormwater control measures.
A Site location map is provided as Figure 1, and the Site and surrounding area with proposed
redevelopment plans are shown in Figure 2.
A brief summary of the Site background and prior environmental assessment activities conducted
at the Site is provided in Section 2.0 below.

SMARTER ENVIRONMENTAL SOLUTIONS

2.0 Site Background
500 and 506 Hoke Street, and 1412 Garner Road
From the 1950s through the 1990s, the portion of the Site comprised of 500 and 506 Hoke Street,
and 1412 Garner Road was utilized by air conditioning equipment and commercial plastic
companies, and as an appliance warehouse and wine and beer distributor. The north -central Site
parcel (506 Hoke Street) and southern Site parcel (1412 Garner Road) are currently unimproved.
The 506 Hoke Street parcel was historically used primarily for parking. The northwestern Site
parcel (500 Hoke Street) is developed with a vacant warehouse building. Past uses of the
warehouse and the 1412 Garner Road parcel included, but are not limited to, waste management
operations by Nyetech Hazardous Waste Transport and other commercial uses. From 2003
through 2004, Nyetech leased the warehouse and reportedly managed waste materials on -Site.
Waste was brought to the Site where it was temporarily stored, solidified, stockpiled, and
repackaged before being transported to off -Site disposal locations.
During Nyetech's operational period, DEQ issued a series of enforcement orders and actions for
non-compliance, which limited Nyetech's operations and subsequently resulted in the excavation
and off -Site disposal of 176.21 tons of soil. In 2004, Nyetech vacated the Site. H&H understands
that historical waste management and corrective action activities were not well documented;
however, according to the BFA, arsenic, and polycyclic aromatic hydrocarbons (PAHs, a subset
of SVOCs) benzo(a)anthracene, benzo(b)fluoranthene, benzo(b)pyrene, and indeno(1,2,3-
cd)pyrene were identified in post -excavation confirmation soil samples at concentrations above
the February 2018 DEQ Preliminary Soil Remediation Goals (PSRGs). PAHs are commonly
found in urban areas and industrial and commercial properties such as the subject Site. As further
discussed below, PAHs were not identified during later soil assessments and as such, are not
considered a significant constituent of concern for the Brownfields Property as evident in their
absence from Exhibit 2 of the BFA.
Starting in 2016, before Passage Home purchased the 500 and 506 Hoke Street and 1412 Garner
Road parcels and then afterwards to provide information for the BFA, Passage Home's
environmental consultants conducted a series of Site assessments. The assessment activities

Raleigh)Brownfields Assessment/Final to DEQBrownfields Assessment Report Hoke St.docx
SMARTER ENVIRONMENTAL SOLUTIONS

targeted areas of potential residual contamination due to Nyetech's waste management operations.
The assessment activities included groundwater, soil, and vapor intrusion -related testing at the
sampling locations shown in Figure 3. The results of the assessment activities are briefly
summarized below:
• Results of soil assessment activities indicated naturally occurring levels of arsenic were
detected above the Residential PSRG. Of note, no other metals and no chlorinated or
petroleum -related volatile organic compounds (VOCs) or semi-VOCs (SVOCs) were
detected in samples collected from the former Nyetech waste management areas or in an
area of a former underground storage tank (UST) northeast of the vacant warehouse
building. As such, former Nyetech operations do not appear to have significantly impacted
the Site, or have been mitigated by corrective action (i.e., soil excavation). As it relates to
liability protection provided in the BFA, only arsenic and the insecticide -related compound
delta-BHC (due to the absence of PSRGs for delta-BHC) are included in the Soil section
of Exhibit 2.
• Results of groundwater assessment activities indicated chromium (up to 29 micrograms
per liter [µg/L]), lead (up to 84 µg/L), and the chlorinated compounds carbon tetrachloride
(2.5 µg/L), tetrachloroethylene (PCE, up to 37 µg/L), and trichloroethylene (TCE, 6 µg/L)
were detected in samples collected from monitoring wells MW-1, MW-2, MW-3, and/or
TW-1 at concentrations above the Title 15A NCAC 2L .0202 Groundwater Standards (2L
Standards). The upper -range detections of PCE and TICE are also above the DEQ
Residential Vapor Intrusion Screening Levels (VISLs) for groundwater.
In general, groundwater impacts were identified in the southwestern portion of the Site in
monitoring wells MW-1, MW-2, and MW-3, and to a lesser extent, TW-1, which is located
in the east -central portion of the Site. As further discussed below, the southwestern portion
of the Brownfields Property is located in close proximity and downgradient to cross -
gradient of the former Ashland LLC Chemical Distribution Facility.

SMARTER ENVIRONMENTAL SOLUTIONS

• Results of sub -slab vapor sampling completed in the vacant warehouse building at 500
Hoke Street indicated PCE (590 micrograms per cubic meter [µg/m3]) was detected above
the DEQ Residential VISL of 280 µg/m3. Evaluation of the sub -slab vapor sampling results
using the October 2017 DEQ Risk Calculator indicated the soil gas to indoor air vapor
intrusion pathway does not pose an unacceptable risk to hypothetical residential or non-
residential building occupants. As previously mentioned, the warehouse building is
currently vacant.
• Based on the chlorinated solvent impacts in groundwater, vapor intrusion assessment was
completed for the vacant warehouse building at 500 Hoke Street. Results of indoor air
sampling completed in May 2018 indicated carbon tetrachloride (0.48 micrograms per
cubic meter [µg/m3]) and naphthalene (up to 2.4 µg/m3) were detected above the DEQ
Residential VISLs. Carbon tetrachloride was also detected in a background ambient air
sample at a similar concentration (0.47 µg/m3). The detection of naphthalene was likely
attributable to indoor sources and not vapor intrusion. Of note, TCE was not detected in
any indoor air sample and PCE was only detected in one of the indoor air samples at a low
level. Specifically, PCE was detected at an estimated concentration (i.e., "J" flag) of 0.13
J µg/m3, which is well below the current Residential VISL of 8.3 µg/m3.
H&H further evaluated the indoor air results using the July 2022 DEQ Risk Calculator by
inputting the highest concentrations of compounds detected in any indoor air sample
collected during the May 2018 sampling event to check a hypothetical worst -case scenario.
Hypothetical worst -case DEQ Risk Calculator indoor air results for a resident indicate a
calculated cumulative carcinogenic risk of 3.1 x 10' and a calculated cumulative hazard
index of 0.89, which do not exceed DEQ acceptable levels.
Results of sub -slab vapor sampling completed in the vacant warehouse building indicated
PCE (590 µg/m3) was detected above the DEQ Residential VISL. Evaluation of the sub -
slab vapor sampling results using the October 2017 DEQ Risk Calculator indicated the soil
gas to indoor air vapor intrusion pathway does not pose an unacceptable risk to hypothetical
residential or non-residential building occupants.

SMARTER ENVIRONMENTAL SOLUTIONS

In summary, results of the previously vapor intrusion assessments indicate that structural
vapor intrusion into the vacant warehouse building at 500 Hoke Street does not pose a
significant risk for hypothetical residential or non-residential users.
As mentioned above, assessment activities completed at the Brownfields Property indicate metals
and chlorinated VOCs have been identified in groundwater and/or sub -slab vapor above DEQ
screening criteria. These constituents were also identified during assessments to investigate the
former Ashland LLC Chemical Distribution Facility, which was located southwest and
topographically downgradient to cross -gradient of the Site. The former Ashland facility was
developed in the late-1960s for warehousing and bulk distribution of industrial chemicals and
solvents. Bulk distribution ceased in the late 1980s and Ashland vacated the facility in 2005. Since
the mid- 1980s, environmental investigations have been completed to evaluate subsurface impacts
associated with the facility. Dating back to at least 2009, groundwater investigations have been
conducted at the facility property and surrounding properties as part of corrective action activities
under Ashland's Resource Conservation and Recovery Act (RCRA) Permit NCD088560032.
A brief description of the operational history of the 1402 Garner Road portion of the Site is
provided below.
1402 Garner Road
The northeastern Site parcel (1402 Garner Road and historical address 1400 Garner Road) is
currently developed with two buildings. The southern building is vacant and was recently utilized
as an automotive repair shop. The northern building is currently operating as a convenience store.
As part of property transaction due diligence activities completed in January 2022, H&H prepared
a Limited Site Evaluation that consisted of a Site visit, desktop review of available records, and a
geophysical survey to identify potential subsurface features such as buried tanks.
According to available records, the 1402 Garner Road parcel operated from 1974 through 1987 as
a gasoline service station under the name Stallings Douglas Union 76. In addition, City of Raleigh
directory listings indicate that the parcel was utilized as a filling station as early as 1931. Other
notable Site occupants include Stallings Pure Oil Service, Stallings Wrecker Service, Coopers

SMARTER ENVIRONMENTAL SOLUTIONS

Mufflers & Brakes, K&L Auto Service, Roberts Auto Service, and Bakers Upholstery & Trim
Shop.
Although the property has been utilized as a service station and automotive repair shop for over
70 years, there are no reported environmental regulatory incidents, leaking tanks, spills, or releases
associated with the parcel. In addition, the property is not a "Regulated site" in that it is neither
listed as a DEQ disposal or incident management site, nor currently subject to an assessment,
cleanup agreement, and/or other regulatory obligations. Based on H&H's limited record review
and an inquiry made to the former property owner, no other environmental information (i.e., Phase
I or Phase II ESAs, UST closure reports, etc.) was available for review.
H&H contracted with GPRS to perform the geophysical survey using electromagnetic and ground
penetrating radar (GPR) equipment. The geophysical survey did not identify the presence of USTs,
although it should be noted that obstructions (i.e., parked vehicles, concrete slabs, etc.) may have
impacted the GPRS's ability to detect tanks. However, tank ventilation pipes located on the
southern wall of the vacant automotive repair building and a fuel dispenser concrete island located
in the eastern portion of the parcel were observed during the geophysical survey. In addition, utility
and/or product piping conduits were observed in the southern portion of the parcel and in an area
where vehicle obstructions were present. Although it was not substantiated by the January 2022
geophysical survey results, it is possible that a UST is or was present in the southern portion of the
parcel (see Section 3.0 below). As such, the potential UST is referred to hereinafter as "Suspect
UST #1."
In early 2022, before Passage Home bought the 1402 Garner Road parcel in August 2022, the
automotive repair shop operations ended. Based on the parcel's historical use as a service station
and automotive repair shop, there is potential for releases to have occurred due to some
combination of leaking suspect UST(s), potential in -ground hydraulic lifts and floor drains,
observed poor management practices of oil and hazardous substances, and use of the parcel as a
vehicle junkyard.

In order to address anticipated DEQ requests for additional assessment at the Site to support the
proposed redevelopment plans, H&H submitted a Brownfields Assessment Work Plan (Work
Plan) dated November 17, 2022. Following review of the Work Plan, DEQ provided comments
in an email dated November 23, 2022. A Revised Work Plan dated November 28, 2022 was
subsequently submitted and received approval via an email dated December 1, 2022.
A summary of Brownfields assessment activities conducted in accordance with the Work Plan is
provided in the following sections.

3.0 Brownfields Assessment Activities
In December 2022, H&H completed Brownfields assessment activities at the Site in accordance
with the DEQ Brownfields-approved Work Plan. The activities included assessment of soil,
groundwater, soil gas, and sub -slab vapor to further evaluate potential impacts at the Site and
potential risk associated with proposed Site redevelopment plans.
The assessment activities were conducted in general accordance with the DEQ Inactive Hazardous
Sites Branch (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines)
dated September 2022, the DEQ Division of Waste Management (DWM) Vapor Intrusion
Guidance dated March 2018, Brownfield's Vapor Intrusion Assessment Work Plan & Report
Checklist (VI Checklist) dated July 2021, and the most recent versions of the U.S. EPA Region IV
Laboratory Services and Applied Science Division (LSASD) Field Branches Quality System and
Technical Procedures guidance.
Prior to conducting field activities, H&H contacted North Carolina 811 One -Call, the locator
service for publicly managed utilities, to mark subsurface utilities at the Site. H&H also contracted
a private utility locator to screen proposed sample locations for subgrade utilities not marked by
the public locator. For added safety, soil borings were hand cleared to 5 ft below ground surface
(bgs) to further screen the boring locations for the presence of subsurface utilities, before
advancing deeper borings with a direct -push technology (DPT) drill rig.
During clearance of utilities for the assessment activities, H&H also instructed the private utility
locator to use a GPR to scan the areas around the buildings located at 1402 Garner Road for
potential USTs. The GPR signal could not penetrate the concrete slabs and, therefore, the presence
of Suspect UST #1 to the south of the automotive repair building could not be substantiated.
However, two potential USTs were identified by the GPR south of the convenience store building
(Suspect UST #2) and west of the automotive repair building (Suspect UST #3). The suspect tank
locations are shown on Figures 2 through 4.

Based on the GPR survey results, the suspect tank dimensions could potentially range from
approximately 5 to 10 ft long and 4 ft wide. These dimensions translate to capacities of
approximately 500 gallons and 1,000 gallons, respectively. Additionally, tank ventilation pipes
were observed in the vicinity of both suspect USTs and a fill port was observed at the ground
surface above Suspect UST #2. H&H was unable to locate historical records pertaining to the
suspect USTs' contents, although the apparent sizes are consistent with heating oil tanks. Based
on the assessment results provided in the following sections, the suspect USTs do not appear to be
a significant source of low-level petroleum impacts identified at the Site and can be managed in
accordance with a DEQ Brownfields-approved Environmental Management Plan (EMP).

4.0 Soil Assessment Activities
On December 1, 2022, H&H and Mid South Environmental, Inc. (Mid South) mobilized to the
Site to advance multiple soil borings. Although proposed redevelopment plans for the Site likely
include minimal ground disturbance, the borings were advanced to evaluate potential impacts from
historical Site operations relative to the potential future building location (i.e., areas of potential
soil disturbance [cut]), and suspect USTs, for on -Site management and/or off -Site disposal
purposes. The locations of the soil borings are shown on Figures 3 and 4 (1402 Garner Road parcel
only), and boring logs are presented in Appendix A.
Details of the soil sampling activities and results are provided in the following sections.
4.1 Soil Sampling Methodology
Mid South used a track -mounted DPT drill rig to advance borings to depths up to approximately
30 ft bgs (as noted below, deeper borings were co -located with temporary monitoring wells).
Shallow soil samples were collected with a decontaminated, stainless steel hand auger. Continuous
soil samples were collected from the borings and logged for lithological description and field
screened for indication of potential impacts by observation for staining, unusual odors, and the
presence of volatile organic vapors using a calibrated photoionization detector (PID). Soil borings
were advanced at the following locations:
• SB-16 (co -located with TW-3) was advanced to approximately 30 ft bgs adjacent to
Suspect UST #1 and within the footprint of the proposed apartment building. Field
observations did not indicate potential impacts (i.e., no elevated PID readings, staining,
and/or odors) and as such, a soil sample was collected from below the approximate bottom
of the suspect UST from approximately 4 to 6 ft bgs. The soil sample was submitted for
laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi-
VOCs (SVOCs) by EPA Method 8270, and Resource Conservation and Recovery Act
(RCRA) metals, plus hexavalent chromium, by EPA Methods 6020/7471/7199.

SMARTER ENVIRONMENTAL SOLUTIONS

• SB-17 (co -located with TW-4) was advanced to approximately 30 ft bgs and located
adjacent to the former fuel dispensers associated with the historical service station. Field
observations indicated PID readings up to 443.1 part per million (ppm) and petroleum
odors in the 2 to 4 ft bgs interval. As such, a soil sample was submitted for laboratory
analysis from this interval for VOCs, SVOCs, and RCRA metals plus hexavalent
chromium using the laboratory methodologies described above for soil sample SB-16.
• SB-18 and SB-19 were advanced in the southeastern portion of the 1412 Garner Road
parcel where no previous soil sampling has occurred. The borings were advanced to
approximately 4 ft bgs to assess near -surface conditions. Field observations did not
indicate potential impacts and as such, soils from the borings were sampled from 0 to 2 ft
bgs. The soil samples were submitted for laboratory analysis of VOCs, SVOCs, and RCRA
metals plus hexavalent chromium using the laboratory methodologies described above for
soil sample SB-16.
• SB-20 and SB-21 were advanced to approximately 4 to 5 ft bgs, respectively, in the central
portion of 1412 Garner Road parcel adjacent to Suspect UST #2. Field observations did
not indicate potential impacts and as such, soils from borings SB-20 and SB-21 were
sampled from the 2 to 4 ft bgs and 4 to 5 ft bgs intervals, respectively. The soil samples
were submitted for laboratory analysis of VOCs, SVOCs, and RCRA metals plus
hexavalent chromium using the laboratory methodologies described above for soil sample
SB-16. In addition, based on laboratory results indicating elevated concentrations of lead
in sample SB-20, the sample was also analyzed for lead by Toxicity Characteristic
Leaching Procedure (TCLP), as described further in Section 4.2.
• SB-22 and SB-23 were advanced to approximately 5 ft bgs adjacent to Suspect UST #3.
Field observations indicated PID readings up to 232.8 (SB-22) and 123.6 (SB-23) and
petroleum odors in the 3 to 4 ft bgs intervals. As such, soil samples were submitted for
laboratory analysis from these intervals for VOCs, SVOCs, and RCRA metals plus
hexavalent chromium using the laboratory methodologies described above for soil sample
SB-16. In addition, based on laboratory results indicating elevated concentrations of lead

in sample SB-23, the sample was also analyzed for lead by TCLP, as described further in
Section 4.2.
Soil samples were placed in dedicated laboratory -supplied sample containers, labeled with the
sample identification, date, and requested analysis, and placed in a laboratory -supplied cooler with
ice. The soil samples were then submitted to a North Carolina -certified laboratory, Eurofins
Laboratory Environmental Testing, LLC (Eurofins), under standard chain of custody protocols for
the analyses as described above. The chain of custody records are provided with the laboratory
analytical reports provided in Appendix B.
Following sampling, the soil borings were properly abandoned with soil cuttings and/or bentonite
and the surface was repaired to pre -sampling conditions. Additionally, the location of each soil
sample was recorded using a hand-held GPS unit.
4.2 Soil Sampling Analytical Results
A tabular summary of the soil sample analytical results is presented in Table 1, and the laboratory
analytical report is provided in Appendix B. The laboratory analytical results were compared to
the DEQ Preliminary Soil Remediation Goals (PSRGs) dated July 2022. In addition to the PSRGs,
metals results were compared to published background ranges for North Carolina soils obtained
from Elements in North American Soils (Elements) authored by Dragun and Chekiri (2005), and
background concentrations of arsenic referenced in a Decision Memorandum prepared for the Site
by DEQ Brownfields dated November 21, 2019. A summary of the soil assessment results is
provided below.
VOCs
Laboratory analytical results indicate low levels of several VOCs were detected above laboratory
method detection limits (MDLs) in soil samples. However, no VOCs were detected above the
Residential or Industrial/Commercial PSRGs, including the samples collected adjacent to suspect
UST locations.

SVOCs
Laboratory analytical results indicate that low levels of SVOCs, including PAHs, were detected in
multiple soil samples above laboratory method detection limits. Specifically, PAH benzo(a)pyrene
(up to 0.496 milligrams per kilogram [mg/kg]), was detected at concentrations above the
Residential PSRG of 0.11 mg/kg in soil samples SB-16, SB-22 and SB-23. No other SVOCs were
detected at concentrations above Residential or Industrial/Commercial PSRGs.
'UP+Qi o
As expected, naturally -occurring background levels of several metals were detected at
concentrations above MDLs in each soil sample. However, only arsenic, hexavalent chromium,
and lead were detected at concentrations above their respective Residential PSRGs. In addition,
lead was detected in SB-23 at a concentration above the Industrial/Commercial PSRG. The metals
results are briefly summarized below:
• Arsenic was detected at concentrations up to 2.93 mg/kg, which is above the Residential
PSRG (0.68 mg/kg) but below and/or within background levels for arsenic as referenced
in the 2019 Decision Memorandum (i.e., <5 mg/kg) and Elements (i.e., <18 mg/kg).
• Total chromium was detected at concentrations ranging from 8.51 mg/kg to 28.0 mg/kg,
which are well within published background levels for North Carolina soils (i.e., <300
mg/kg). Speciation of total chromium was performed via analysis of hexavalent
chromium, which indicated hexavalent chromium concentrations ranging from 0.455 J
mg/kg to 3.31 mg/kg. The Residential and Industrial/Commercial PSRGs for hexavalent
chromium are 0.31 mg/kg and 6.5 mg/kg, respectively.
H&H is unaware of published background concentrations for hexavalent chromium in
North Carolina. Although the presence of hexavalent chromium in the environment may
be the result of anthropogenic activity, hexavalent chromium is potentially present in
background soil. For example, the New Jersey Department of Environmental Protection
(NJDEP) conducted a study of background levels of hexavalent chromium in soil. Results
indicated that of the 258 samples analyzed, 36% contained detectable concentrations of

SMARTER ENVIRONMENTAL SOLUTIONS

hexavalent chromium, with a 75th percentile concentration of 1.4 mg/kg and a 99th
percentile concentration of 5.5 mg/kg'. As such, the hexavalent chromium concentrations
at the Site could be indicative of background conditions.
• Lead was detected in two soil samples (445 mg/kg [SB-20] and 950 mg/kg [SB-23]) at
concentrations above the Residential PSRG of 400 mg/kg, Industrial/Commercial PSRG
of 800 mg/kg (SB-23 only), and published background levels for North Carolina soils (i.e.,
>50 mg/kg). In both the SB-20 and SB-23 samples, the lead concentrations are greater
than 20 times the hazardous characteristic threshold concentration for lead (i.e., Rule of 20
evaluation). Therefore, these two samples were also analyzed for TCLP lead.
Results of the TCLP analyses indicate lead at a concentration of 6.27 milligrams per liter
(mg/L) in the soil sample located adjacent to Suspect UST #3 (SB-23 [3 to 4 ft bgs]), which
is above the Federal Toxicity Characteristic Level of 5.0 milligrams per liter (mg/L) as
defined in 40 CFR Subpart C 261.24 (hazardous characteristic threshold level). As such,
soil in the vicinity of SB-23 and Suspect UST #3 has the potential to leach lead above the
hazardous characteristic threshold level. Lead was not detected above the hazardous
characteristic threshold level in soil sample SB-20 (2-4 ft bgs). A summary of soil TCLP
analytical data is provided in Table 2.
4.3 Direct Soil Contact Risk Evaluation
The DEQ PSRGs used for comparison to the laboratory analytical results are conservative and
based upon a target Lifetime Incremental Cancer Risk (LICR) of 1.0 x 10-6 for potential
carcinogenic effects and a Hazard Quotient (HQ) of 0.2 for potential non -carcinogenic effects. The
DEQ and EPA acceptable level for potential carcinogenic risks is a cumulative LICR of 1.0 x 10-
4 or less, and the acceptable level for non -carcinogenic risks is a cumulative HI of 1.0 or less.

SMARTER ENVIRONMENTAL SOLUTIONS

To further evaluate soil samples that may remain on -Site post redevelopment or will be potentially
disturbed during redevelopment activities, H&H utilized the DEQ Risk Calculator (July 2022) to
evaluate soil direct contact risks under hypothetical "worst -case" resident and non-residential
worker use scenarios.
To conduct the risk evaluation, H&H input the highest concentration of each compound detected
in the soil samples into the DEQ Risk Calculator. A copy of the completed DEQ Risk Calculator
is provided in Appendix E. The Risk Calculator results are summarized in Table 1 and discussed
further below.
• Hypothetical worst -case DEQ Risk Calculator soil risk results for a resident indicate a
calculated cumulative LICR of 2.1 x 10' and a calculated cumulative HI of 0.24, which do
not exceed DEQ acceptable levels;
• Hypothetical worst -case DEQ Risk Calculator soil risk results for a non-residential worker
indicate a calculated cumulative LICR of 1.8 x 10' and a calculated cumulative HI of
0.017, which do not exceed DEQ acceptable levels.
In summary, the hypothetical worst -case cumulative carcinogenic and non -carcinogenic risks do
not exceed DEQ acceptable levels. As such, there does not appear to be an unacceptable soil direct
contact exposure risk to current or future Site users.

5.0 Groundwater Assessment Activities
On December 1, 2022, H&H provided oversight during the installation of two temporary
groundwater monitoring wells. The locations of the temporary monitoring wells (identified as
TW-3 and TW-4) in conjunction with proposed redevelopment plans are shown on Figures 3 and
4 (1402 Garner Road parcel only), and were advanced in the following locations:
• TW-3 (co -located with SB-16) was advanced to approximately 30 ft bgs and located within
the footprint of the proposed building and adjacent to Suspect UST #1.
• TW-4 (co -located with SB-17) was advanced to approximately 30 ft bgs and located
adjacent to the former service station's fuel dispensers.
Details of the groundwater sampling activities and results are provided in the following sections.
5.1 Temporary Monitoring Well Installation
The temporary monitoring wells were installed utilizing DPT drilling techniques to advance the
well boring into the subsurface until sufficient groundwater was encountered. The first 5 feet of
each boring were advanced using a decontaminated stainless steel hand auger. Continuous soil
samples were collected from the borings and logged for lithologic description, screened using
visual and olfactory methods for obvious evidence of staining or unusual odors, and screened for
the presence of volatile organic vapors using a calibrated PID. As mentioned in Section 4.1, field
observations indicated PID readings up to 443.1 ppm and petroleum odors in the 2 to 4 ft bgs
interval from the TW-3 boring. No obvious evidence of impacts was observed in the TW-3 boring.
The temporary monitoring wells were constructed of 1-inch diameter PVC with 10 ft of slotted
well screen set to bracket the water table and 1-inch diameter PVC well casing to the ground
surface. A sand filter pack extended from the base of the boring to approximately 1-2 ft above the
top of the pre -packed well screens followed by at least 2 ft of hydrated bentonite. The temporary
monitoring wells were installed to depths of approximately 30 ft bgs. Temporary monitoring well

SMARTER ENVIRONMENTAL SOLUTIONS

construction details and depth to groundwater information are presented in Table 3, and boring
logs are presented in Appendix A.
Prior to sampling, TW-4 was developed by removing a minimum of three to five well volumes
and until field parameters stabilized (i.e., pH ± 0.1 SU, conductivity varies no more than 5%, and
turbidity is less than 10 NTUs). Due to a low groundwater recharge rate, TW-3 was developed by
purging until the well became dry. Groundwater sampling forms completed are provided in
Appendix C.
5.2 Temporary Monitoring Well Gauging
Following development of the temporary monitoring wells, the wells were allowed to equilibrate
to static conditions after approximately 48 hours. Subsequently, a decontaminated electronic water
level indicator was used to measure the depth to the water table relative to the ground top of well
casing. Groundwater was measured at depths ranging from approximately 27.63 ft below top of
casing (btoc) in TW-3, and 28.98 ft btoc in TW-4. Based upon area topography, the implied
groundwater flow direction is to the south. A tabular summary of depth to groundwater
measurements is provided in Table 3.
5.3 Groundwater Sampling Methodology
Following collection of depth to groundwater measurements, groundwater samples were collected
from the temporary monitoring wells using low-flow/low-stress purging techniques via a
peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing was
placed in the approximate mid -portion of the screened interval of each well and groundwater was
removed at a rate no greater than 200 milliliters per minute. H&H used a water quality meter to
measure pH, temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific
conductivity at 3 to 5-minute intervals during purging.
Groundwater samples were collected directly into laboratory supplied sample containers. VOC
samples were collected using the "soda straw" method to minimize volatile loss through the

SMARTER ENVIRONMENTAL SOLUTIONS

peristaltic pump head. Specifically, sample tubing was removed from the well and used to fill the
sample containers by reversing the flow direction of the peristaltic pump. The sample containers
were labeled with the sample identification, date, and requested analysis, and then placed in a
laboratory supplied cooler and iced. The groundwater samples were delivered to Contest under
standard chain of custody protocols for analysis of VOCs by EPA Method 8260, SVOCs by EPA
Method 8270, and RCRA metals by EPA Methods 6020/7470.
After sampling, temporary monitoring wells TW-3 and TW-4 were abandoned by Mid South and
the ground surfaces were repaired to pre -drilling conditions. The groundwater sample locations
were recorded in the field using a hand-held GPS unit. Well abandonment records are provided in
Appendix A.
5.4 Groundwater Analytical Results
A tabular summary of groundwater sample analytical results is presented in Table 4. The
laboratory analytical report and chain -of -custody records are provided in Appendix B.
Groundwater data were compared to the Title 15A NCAC 02L.0202 Groundwater Standards (2L
Standards) amended April 1, 2022. A summary of the groundwater assessment results is provided
below.
VOCs and SVOCs
Laboratory analytical results indicate no VOCs or SVOCs were detected above MDLs in
groundwater samples collected from TW-3 and TW-4.
Metals
Laboratory analytical results indicate that low levels of barium, cadmium, chromium, lead, and
selenium were detected in at least one of the groundwater samples at concentrations above MDLs,
but below their respective 2L Standards.

6.0 Sub -Slab Vapor and Soil Gas Assessment Activities
On December 1 through 6, 2022, H&H conducted sub -slab vapor and soil gas assessment activities
at the Site to evaluate the potential for structural vapor intrusion into the current buildings and the
planned apartment building. Four temporary soil gas monitoring points (SG-1 through SG-4) and
four temporary sub -slab vapor monitoring points (SS-5 through SS-8) were installed within the
footprint of the proposed building. Sub -slab vapor (represented by SS nomenclature) and soil gas
(represented by SG nomenclature) locations relative to proposed redevelopment plans are depicted
in Figures 3 and 4 (1402 Garner Road parcel only).
Details of the assessment activities and results are provided in the following sections.
6.1 Soil Gas and Sub -Slab Vapor Sampling Activities
H&H installed the soil gas monitoring points by advancing borings via a decontaminated, stainless
steel hand auger to approximately 5.5 ft bgs or to a shallower refusal depth, based on subsurface
conditions. During the advancement of soil gas monitoring point borings SG-1 and SG-2 and soil
borings SB-20 through SB-23, debris generally consisting of brick, plastic, wood, asphalt, rubber,
and glass were identified. As such, select soil gas monitoring points were evaluated for the
presence of methane and other subsurface gases as further described below
The soil gas points were each installed with a 6-inch long, 0.010-inch diameter stainless steel
screen that was set at the base of the boring and connected to the ground surface with 1/4-inch
Teflon® tubing. The annular space of the boring was then filled with filter sand followed by a
hydrated bentonite seal to prevent short-circuiting of air from the surface. Prior to collecting the
soil gas samples, the monitoring points were allowed to equilibrate for at least 48 hours following
installation.
The sub -slab gas monitoring points were installed using a Cox Colvin Vapor PinTM kit (vapor pin).
To install the vapor pins, H&H used a hammer drill equipped with a 5/8-inch diameter bit to
penetrate the concrete slab. Following borehole advancement, loose cuttings were removed with
a shop -vac to allow installation of the vapor pin. The vapor pin assembly (brass sampling point

SMARTER ENVIRONMENTAL SOLUTIONS

and silicone sleeve) was placed and seated in the drilled hole by tapping the assembly into place
using the installation/extraction tool and a dead blow hammer. The vapor pins were then connected
to 1/4-inch Teflon® tubing to allow for the sampling procedures described below. Prior to
collection of the sub -slab vapor samples, the monitoring points were allowed to equilibrate for at
least two hours following installation.
Following sample point equilibration and prior to sample collection, a Landtec GEM 50009
(GEM) was connected to the sample Teflon® tubing and field measurements of static and
differential pressure readings were collected from each sampling point. After pressure readings
were collected, a "shut-in" test was conducted on the sampling train and helium leak checks were
conducted at each sampling point. The purpose of the shut-in test and helium leak check are to
minimize the potential for short circuiting with ambient air during sampling. The shut-in test and
leak check are described below:
• The shut-in test was conducted by connecting the flow regulator with the vacuum gauge to
the Summa® canister and sealing the flow regulator with the laboratory provided brass cap.
Once the sampling train was "closed", the sample valve on the Summa® canister was
opened and the reading on the vacuum gauge was recorded. The Summa® canister sample
valve was then closed, and the vacuum gauge was observed to ensure no vacuum loss
occurred. Because the vacuum readings remained generally the same, the shut-in tests
were considered successful.
• Prior to soil gas and sub -slab vapor sampling, H&H conducted a leak check at each sample
location by constructing a shroud around the sampling point, sampling fittings, and
sampling connections, and flooding the air within the shroud with helium gas. Helium
within the shroud was monitored using a helium gas detector. A sample was then collected
from the sample tubing outside the shroud into a Tedlar bag and analyzed using the helium
gas detector. Using a syringe and three-way valve, the Teflon® sample tubing was purged
using the GEM while field measurements of pressure, oxygen, carbon dioxide, and
methane (percent by volume and percent lower explosive limit) were concurrently
collected. Note that field measurements were not collected from sub -slab vapor point SS-
5 and SS-6 during the field data collection period due to their abandonment prior to the
21

SMARTER ENVIRONMENTAL SOLUTIONS

methane assessment. The results of the leak check indicated that helium concentrations in
the Tedlar bags were less than 10% of the helium concentrations measured within the
shrouds. As such, each sample passed the leak test.
The primary migration mechanism for methane is advective transport (i.e., pressure -driven). To
evaluate the potential for static pressure generation under existing conditions, which could
potentially be indicative of future conditions, pressure readings were collected from the soil gas
and sub -slab vapor points. Based on extensive discussions with the GEM manufacturer, the "static
pressure" reading reported by the GEM is collected from a pressure transducer located at the
influent point where tubing from the sampling point enters the meter. The instrument is "zeroed
out" prior to connection to the sampling point tubing, which effectively removes the atmospheric
pressure from the reading. Therefore, the "static pressure" reported by the GEM is equal to the
pressure in the sampling point minus atmospheric pressure. A positive static pressure reading
reflects subsurface pressure above atmospheric, while a negative static pressure reading reflects a
vacuum in the subsurface. The "differential pressure" reading reported by the GEM is collected
from a pressure transducer located at the effluent point for the meter and reflects the pressure
exiting the unit. The "differential pressure" reported by the GEM is typically similar to and inverse
the static pressure (i.e., positive static pressure equals negative differential pressure and vice
versa). In addition, it should be noted that the GEM's estimated accuracy as reported by the
manufacturer is +/-0.5% for methane, +/-2.0 inches of water (in H20) for static pressure, and
+/-0.7 inches of H2O for differential pressure.
Following successful leak checks and methane sampling, the sub -slab vapor and soil gas samples
were collected into laboratory -supplied 1-liter batch -certified stainless steel Summa canisters
connected to inline flow controllers with laboratory -calibrated vacuum gauges. Vacuum readings
on the Summa canisters were checked prior to sampling to confirm no vacuum loss greater than
10% of the initial recorded lab vacuum when received in the field. The flow controllers were
connected to the sample tubing at each sampling point using a brass nut and ferrule assembly to
form an air -tight seal. The flow regulators were pre-set by the laboratory to regulate the intake rate
to less than approximately 200 millimeters per minute. The intake valve on each canister was fully
opened to begin collection of the soil gas samples. The initial canister vacuums were 20 to 30

SMARTER ENVIRONMENTAL SOLUTIONS

inches of mercury and the final canister vacuums were approximately 3 to 5 inches of mercury at
the conclusion of the sampling event, per laboratory standard operating procedures.
After sample collection, the intake valve was closed, and the regulator was disconnected from the
sample canister. The canisters were placed in laboratory supplied shipping containers, properly
labeled, and shipped under standard chain -of -custody protocols to Eurofins for analysis of VOCs
by EPA Method TO-15.
Soil gas monitoring locations were surveyed using a hand-held GPS unit. Sub -slab vapor
monitoring point locations were estimated based upon referencing distances to building landmarks.
Following sampling, the monitoring points were properly abandoned and surfaces were repaired
to pre -drilling conditions. IDW generated during the assessment activities was thin spread on -Site
as there was no evidence of significant impacts in the soil gas monitoring point borings. Soil gas
monitoring point boring logs are provided in Appendix A.
6.2 Soil Gas and Sub -Slab Vapor Analytical Results
The results of analysis of the sub -slab vapor and soil gas samples are summarized in Table 5. The
laboratory analytical report and chain -of -custody records are provided in Appendix B. Sub -slab
vapor and soil gas sample analytical results were compared to the July 2022 DEQ Residential and
Non -Residential SGSLs. A summary of the vapor intrusion assessment results is provided below.
VOCs
Laboratory analytical results indicate benzene (17 micrograms per cubic meter [µg/m3], SG-2) was
detected at a concentration above the Residential SGSL of 12 µg/m3. No other VOCs were detected
at concentrations above their respective Residential SGSLs in sub -slab vapor or soil gas samples.
In addition, TCE was not detected above the laboratory MDLs in any of the sub -slab vapor or soil
gas samples.

Methane and Pressure Screening Results
Results of the methane gas screening activities indicate no detectable concentrations of methane
were identified in soil gas or sub -slab samples. Based on these results, methane does not appear to
be a significant concern at the Site. A summary of methane and pressure screening results is
provided in Table 6.
The static pressure measured in the sub -slab vapor and soil gas monitoring points ranged from
—0.3 to 0.16 in H2O. As previously mentioned, the accuracy of the GEM is +/— 2 in H2O for static
pressure. As such, the static pressure readings are below the accuracy limits of the instrument and
considered negligible.
6.3 DEQ Vapor Intrusion Risk Calculations
Consistent with DEQ's Vapor Intrusion Guidance, soil gas and sub -slab detections were compared
to the DEQ SGSLs as part of a preliminary vapor intrusion evaluation. The DEQ SGSLs are
conservative and based on a LICR for potential carcinogenic risks of 1.0 x 10-6 and a non -
carcinogenic HQ of 0.2 for potential non -carcinogenic risks. The DEQ and EPA acceptable risk
range for potential carcinogenic risks is 1.0 x 10-4 to 1.0 x 10-6 or less and the acceptable level for
non -carcinogenic risks is a HI less than 1.0.
To further evaluate potential structural vapor intrusion beyond comparison of soil gas and sub -slab
detections to the DEQ SGSLs, H&H calculated cumulative risks using the July 2022 DEQ risk
calculator. Specifically, hypothetical "worst -case" scenario calculated cumulative risks were
evaluated for the soil gas to indoor air vapor intrusion pathway for detected VOCs in the soil gas
and sub -slab vapor samples. For the hypothetical "worst case" scenario, the highest concentration
of each compound detected in any soil gas or sub -slab vapor sample was input into the calculator.
Results of the risk calculations are summarized in Table 5, included in Appendix D, and discussed
further below.

SMARTER ENVIRONMENTAL SOLUTIONS

• Hypothetical worst -case DEQ Risk Calculator soil gas to indoor air risk results for a
resident indicate a calculated cumulative LICR of 2.4 x 10' and a calculated cumulative
HI of 0.12, which do not exceed DEQ acceptable levels; and
• Hypothetical worst -case DEQ Risk Calculator soil gas to indoor air risk results for a non-
residential worker indicate a calculated cumulative LICR of 1.8 x 10-7 and a calculated
cumulative HI of 0.0098, which do not exceed DEQ acceptable levels.
In summary, hypothetical worst -case DEQ Risk Calculator soil gas to indoor air risk results do not
exceed DEQ acceptable levels. Based on soil gas and sub -slab vapor samples collected from the
Site, there does not appear to be an unacceptable vapor intrusion risk to current or future Site users.

7.0 Quality Assurance — Quality Control
For quality assurance and quality control purposes (QA/QC), non -dedicated equipment and tools
were decontaminated prior to use at each boring or sampling location or following exposure to
soil, soil gas, sub -slab vapor, and/or groundwater. Field QA/QC samples were analyzed along
with the investigative samples to determine potential variability introduced in sampling, handling,
shipping, and analysis. Two trip blanks accompanied H&H sampling personnel during the
assessment activities. The trip blanks were submitted for analysis of VOCs by EPA Method 8260.
In addition, H&H collected duplicate soil, groundwater, soil gas, and sub -slab vapor samples to
evaluate the ability of the laboratory to reproduce sample results. Duplicate samples were submitted
to the laboratory for the same analysis as the corresponding parent sample.
Laboratory QA/QC procedures were employed to ensure appropriate sample handling and analysis
and to aid in the review and validation of the analytical data. QA/QC procedures were conducted
in accordance with the method protocols and included regular equipment maintenance, equipment
calibrations, and adherence to specific sample custody and data management procedures. Samples
were analyzed in conjunction with appropriate blanks, laboratory duplicates, continuing
calibration standards, surrogate standards, and matrix spiking standards in accordance with
approved methodologies to monitor both instrument and analyst performance. Laboratory
reporting limits for each analyte were at or below appropriate screening criteria, where possible.
Additionally, H&H requested that the laboratory include estimated concentrations for compounds
that were detected at levels above the laboratory method detection limit, but below the laboratory
reporting limit (i.e., "J" flags). Note that mercury by EPA Method 7470 was analyzed outside of
the analytical holding time for groundwater sample TW-3 due to an inadvertent miscommunication
with the laboratory. However, based on the laboratory analytical results for the soil samples and
groundwater sample TW-2, the out -of -hold mercury analytical result for TW-3 does not appear to
significantly impact the conclusions of this report.

7.1 Trip Blank
The trip blanks were prepared by the laboratory and consisted of certified -clean sample containers
filled with analyte-free water. The trip blanks accompanied the empty laboratory sample containers
to the Site, remained within the sample coolers during sampling, and traveled back to the
laboratory with field samples. The purpose of a trip blanks was to evaluate sample handling
conditions and the potential for external contaminants to compromise investigative samples during
transit. One trip blank accompanied the VOC soil and groundwater samples during the sampling
event on December 1, 2022, and another trip blank accompanied the groundwater sample collected
on December 5, 2022. Both trip blanks were submitted for laboratory analysis of VOCs by EPA
Method 8260.
Laboratory analytical results of the trip blanks sample indicate that no VOCs were detected above
the laboratory MDLs. Laboratory analytical results of the trip blanks are included in the laboratory
analytical reports in Appendix B.
7.2 Field Duplicates
Duplicate samples were collected to evaluate the precision of the field sampling procedures,
sample matrix variability, and analytical reproducibility. Duplicate soil and groundwater samples
were collected directly into individual laboratory supplied sample containers using sampling
methodologies described in previous sections. The duplicate soil gas and sub -slab vapor samples
were collected concurrently with the parent samples using a laboratory supplied T-sampler which
allows for collection of two samples from the same location simultaneously. Each duplicate
sample was analyzed for the same parameters as the parent sample, and the analytical results were
compared with those of the parent sample. The analytical results of the parent sample and the
duplicate sample were used to evaluate the cumulative precision of the analytical method, sample
matrix, and sample collection techniques.

Duplicate sample laboratory analytical results for each sample media are presented in the summary
tables. Review of the duplicate sample results for the soil, groundwater, soil gas, and sub -slab
vapor samples did not indicate significant variability compared with the results of the parent

8.0 Investigation Derived Waste (IDW)
There was no evidence of significant impacts in the soil, soil gas monitoring points, or temporary
monitoring well borings. Therefore, investigation derived waste (IDW) was spread/discharged on
the ground in accordance with DEQ IHSB Guidelines and the DEQ-approved Work Plan.

9.0 Summary and Conclusions
H&H has completed Brownfields assessment activities at the Hoke Street Passage Home
Brownfields Property located in Raleigh, North Carolina. The assessment activities were
conducted in accordance with the DEQ Brownfields-approved Revised Brownfields Assessment
Work Plan dated November 28, 2022. Brownfields assessment activities included the collection
of soil, groundwater, soil gas, and sub -slab vapor samples to evaluate potential impacts at the Site
and potential risks associated with proposed Site redevelopment plans. A brief summary of the
results of the Brownfields assessment activities is provided below.
• Two suspect heating oil USTs were identified on the 1402 Garner Road parcel.
Specifically, the suspect USTs are located south of the convenience store building (Suspect
UST #2) and west of the automotive repair building (Suspect UST #3). The suspect tank
dimensions could potentially range from approximately 5 to 10 ft long and 4 ft wide, with
capacities ranging from approximately 500 gallons to 1,000 gallons. Additionally, tank
ventilation pipes, a fuel dispenser concrete island, and utility and/or product piping were
observed in the southern and eastern portions of the parcel. As such, it is possible that a
UST is or was present in the southern portion of the parcel (i.e., Suspect UST #1). H&H
was unable to locate historical records pertaining to the three suspect USTs' contents,
although the potential presence of USTs is consistent with the former use of the 1402
Garner Road parcel as a petroleum station from the 1930s until the 1980s.
• Results of soil assessment activities indicate low levels of the PAH benzo(a)pyrene were
identified at concentrations above the Residential PSRG in soil samples SB-16, SB-22 and
SB-23 collected adjacent to Suspect UST #1 and/or Suspect UST #3. No other SVOCs
and no VOCs were detected at concentrations above the Residential or
Industrial/Commercial PSRGs in the soil samples.
Lead was detected in soil samples SB-20 and SB-23 at concentrations above the Residential
PSRG, Industrial/Commercial PSRG (SB-23 only), published background levels for North
Carolina soils, and 20 times the hazardous characteristic threshold concentration for lead.
Results of TCLP analyses indicate lead at a concentration above the hazardous

characteristic threshold level in the soil sample located adjacent to Suspect UST #3 (SB-
23 [3 to 4 ft bgs]). As such, soil in the vicinity of SB-23 and Suspect UST #3 has the
potential to leach lead above the hazardous characteristic threshold level.
Arsenic and total chromium were detected at concentrations below and/or within published
and Site -specific background levels. Speciation of total chromium was performed via
analysis of hexavalent chromium, which indicated hexavalent chromium was identified at
concentrations above the Residential PSRG. Based on a published study for hexavalent
chromium in New Jersey soils, the hexavalent chromium concentrations at the Site could
be indicative of naturally occurring background conditions.
H&H utilized the DEQ Risk Calculator to further evaluate the hypothetical worst -case
potential risks for the direct soil contact exposure pathway under residential and non-
residential use scenarios. Calculated cumulative risks for current and/or future residents
and non-residential workers are within the acceptable carcinogenic risk of less than 1.0 x
10' and less than a hazard index of 1.0. As such, there does not appear to be an
unacceptable exposure risk for soil direct contact to current or future Site users.
• Results of groundwater assessment activities indicate no VOCs or SVOCs were detected
in groundwater at concentrations above the MDLs. In addition, low levels of barium,
cadmium, chromium, lead, and selenium were detected in at least one of the temporary
groundwater monitoring well samples at concentrations above MDLs, but below their
respective 2L Standards.
• Results of vapor intrusion assessment activities indicate benzene was detected at a
concentration above the Residential SGSL in one of the soil gas samples. No other VOCs
were detected at concentrations above Residential SGSLs in sub -slab vapor or soil gas
samples In addition, TCE was not detected above the laboratory MDL in any of the sub -
slab vapor or soil gas samples.

To further evaluate potential vapor intrusion risks, H&H utilized the DEQ Risk Calculator
to evaluate hypothetical worst -case potential vapor intrusion risks for the soil gas to indoor
air pathway under residential and non-residential use scenarios. Calculated cumulative
risks for current and/or future residents and non-residential workers are within the
acceptable carcinogenic risk of less than 1.0 x 10-4 and less than a hazard index of 1.0. As
such, there does not appear to be an unacceptable vapor intrusion risk to current or future
Site users.
• Results of methane gas screening activities indicate no detectable concentrations of
methane were identified in soil gas or sub -slab samples Based on these results, methane
does not appear to be a significant concern at the Site. To evaluate the potential for static
pressure generation under existing conditions, which could potentially be indicative of
future conditions, pressure readings were collected from the soil gas and sub -slab vapor
points. Static pressure measured in the sub -slab vapor and soil gas monitoring points are
below the accuracy limits of the instrument and considered negligible.

2) Risk evaluation performed using the highest soil gas contaminant concentrations entered into the July 2022 DEQ Risk Calculator for the residential and non-residential soil gas to indoor air vapor intrusion pathway.
Concentrations are reported in micrograms per cubic meter (pg/m 3). Compound concentrations are reported to the laboratory method detection limits.
Laboratory analytical method is shown in parentheses.
Only compounds detected in at least one sample are shown in the above table.
Grey shading and bolding indicate values exceed the Residential SGSLs.
VOCs = volatile organic compounds; NE = not established
J = Compound was detected above the laboratory method detection limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.
CN = The presence of a closely eluting non -target peak in samples SG-2, SS-5, SS-8 and SS-DUP isinterfering with the quantitation mass ion for 4-Ethyltoluene. The reported 4-Ethyltolueneconcentration is flagged with a "CN" flag to indicate a high bias due to matrix contribution.
E = Exceeds instrument calibration range.

Notes:
Measurements were collected by H&H using a calibrated Landtec GEM 5000 (GEM or unit).
The static pressure transducer on the GEM is located at the point where tubing from the sampling point enters the unit. The unit is zeroed out to atmospheric pressure before the tubing from the sampling point is connected. Therefore, the adjusted static pressure as reported by the GEM is the pressure in the sampling point minus atmosphe
pressure. A positive value indicates subsurface pressure greater than atmospheric pressure. The differential pressure transducer on the GEM is located at the effluent port. The adjusted differential pressure measurement on the GEM is typically similar to and inverse the static pressure measurement.
OZ= Oxygen; COZ = Carbon Dioxide; CO = Carbon Monoxide; FtS = Hydrogen Sulfide
% = Percent by volume in air; ppm = parts per million in air; in Hg = inches of mercury; in I-)O = inches of water
ft bgs = feet below ground surface; NA = Not Available

Receipt
The samples were received on 12/3/2022 6:00 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperatures of the 3 coolers at receipt time were 1.3°C, 1.8°C and 2.1 °C
GC/MS VOA
Method 8260D: Surrogate recovery for the following samples were outside the upper control limit: TW-4 (680-226843-10) and TW-4 DUP
(680-226843-11). This sample did not contain any target analytes; therefore, re -extraction and/or re -analysis was not performed.
Method 8260D: The laboratory control sample (LCS) for analytical batch 680-754637 recovered outside control limits for the following
analytes: lodomethane, Acetone, Chloroethane, Chloromethane and Ethylene Dibromide. These analytes were biased high in the LCS
and were not detected in the associated samples; therefore, the data have been reported.
Method 8260D: The laboratory control sample duplicate (LCSD) for analytical batch 680-754637 recovered outside control limits for the
following analytes: Carbon disulfide, lodomethane, 2-Hexanone, Vinyl Chloride, Dibromomethane, Acetone, Chlorobromomethane,
Chloroethane, 1,3-Dichloropropane, Chlorodibromomethane, 1,1,2-Trichloroethane, Chloromethane, Methyl Chloride,
4-Methyl -2-pentanone, Ethylene Dibromide and 2-Butanone. These analytes were biased high in the LCSD and were not detected in the
associated samples; therefore, the data have been reported.
Method 8260D: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for analytical batch 680-754637
recovered outside control limits for the following analyte: Acetone.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC/MS Semi VOA
Method 8270E_SIM: The following samples listed formed emulsions during the extraction procedure: TW-4 (680-226843-10) and TW-4
DUP (680-226843-11). The emulsions were broken up using Sodium Sulfate.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

LABORATORY NARRATIVE
EPA Method TO-15
Eurofins Environment Testing
Workorder# 2212224
Ten 1 Liter Summa Canister (100% Certified) samples were received on December 07, 2022. The
laboratory performed analysis via EPA Method TO-15 using GC/MS in the full scan mode.
Receiving Notes
The Chain of Custody was missing method information or contained incorrect method information.
EATL proceeded with the analysis as per the original contract or verbal agreement.
Analytical Notes
As per client project requirements, the laboratory has reported estimated values for target compound hits
that are below the Reporting Limit but greater than the Method Detection Limit. Concentrations that are
below the level at which the canister was certified may be false positives.
All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined
at the bottom of this Case Narrative and on each Sample Result Summary page. Target compound
non -detects in the samples that are associated with high bias in QC analyses have not been flagged.
The presence of a closely eluting non -target peak in samples SG-2, SS-5, SS-8 and SS-DUP is
interfering with the quantitation mass ion for 4-Ethyltoluene. The reported 4-Ethyltoluene
concentration is flagged with a "CN" flag to indicate a high bias due to matrix contribution.
Definition of Data Oualifying Flags
Ten qualifiers may have been used on the data analysis sheets and indicates as follows:
B - Compound present in laboratory blank greater than reporting limit (background subtraction not
performed).
J - Estimated value.
E - Exceeds instrument calibration range.
S - Saturated peak.
Q - Exceeds quality control limits.
U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See
data page for project specific U-flag definition.
UJ- Non -detected compound associated with low bias in the CCV
N - The identification is based on presumptive evidence.
M - Reported value may be biased due to apparent matrix interferences.
CN - See Case Narrative.
File extensions may have been used on the data analysis sheets and indicates
as follows:
a -File was requantified
b-File was quantified by a second column and detector
rl-File was requantified for the purpose of reissue

Notes: Shut -In Test should be performed with matching canister with regulator as listed by laboratory on canister tag, and should last for a duration of at least 5 minutes.
Regulator "Zero" Pressure = pressure of regulator detached from Summa (if not 0 " Hg, then this needs to be accounted for during sampling).
Summa Initial Pressure = pressure of Summa immedietely after closing valve (pressure likely to decrease slighlty once valve is closed).
