National Linen
1 EXECUTIVE SUMMARY
October 20, 2020
Page 1
The National Linen site is located at 1315 South 5t" Avenue in Wilmington. The 2.6-acre
site consists of the three parcels. The largest parcel is zoned UMX-Urban Mixed Use and
was home to the former National Linen industrial laundry facility from circa 1950 until
2010. For the last ten years, the site was used as a storage warehouse. The main parcel
is improved with a 43,000-sq-ft building, which was home to the laundry. The two smaller
out -parcels are unused and unimproved and zoned Light Industrial.
This report provides the assessment finding for soil gas, soil, and groundwater testing
conducted at the National Laundry site. Testing focused on the largest parcel, which was
home to the laundry. There are no known concerns associated with the two smaller out -
parcels, and therefore no testing was conducted on either out -parcel.
Samples were collected from across the property to address data gaps and provide
information on possible recognized environmental conditions (i.e., contamination). The
assessment was also intended to help guide due diligence, identify the land use
restrictions and mitigation measures needed to safely redevelop the property, and provide
suitable information for a Brownfields Agreement with North Carolina's Department of
Environmental Quality (DEQ).
The assessment was thorough and complete and conducted in general accordance with
DEQ guidelines. It included seven soil boring sampling locations and seven temporary
groundwater well sampling locations. Soil and groundwater samples were analyzed for
volatile organic compounds (VOCs), semi -volatile organic compounds (SVOCs) and
RCRA metals. Soil gas testing was conducted to evaluate possible vapor intrusion (VI)
risk and included soil gas samples collected from seven locations at the laundry that were
analyzed by US EPA Method TO-15.
Only limited, low-level contamination was found at National Linen. Soil and groundwater
had no measurable contamination above DEQ standards or guidelines for both
commercial and residential site use. Soil gas testing showed no unacceptable VI risk for
commercial redevelopment of the property, which is intended. For possible residential
site use, which is not the current redevelopment plan, further assessment of potential VI
risks is warranted, but only if residential development is planned.
The redevelopment of the National Linen site was deemed eligible to participate in the
Brownfields Program on June 30, 2020. Fifth Street Investors, LLC and Raleigh
Restoration Group, LLC are co -Prospective Developers. The current redevelopment plan
for the site is as a commercial brewery and retail food hall. However, other types of
commercial redevelopment options are possible and residential development will be
requested as an allowable future site use.
The Brownfields Program was established under the Brownfields Property Reuse Act of
1997 [NCGS 130A310.30 et seq.]. This statute authorizes DEQ to work with prospective
developers (provided they did not cause or contribute to site contamination) to promote
the redevelopment of urban infill properties, old industrial sites, and other types of
underutilized, environmentally impaired real estate.

National Linen is located at 1315 South 5t" Avenue in Wilmington. Location maps and site
map showing the areas investigated are attached as Figures 1, 2 and 3, respectively.
The 2.6-acre site consists of the three parcels listed below. The largest parcel is zoned
UMX-Urban Mixed Use and was home to the former National Linen laundry facility and
improved with a 43,000-sq-ft building. The two smaller lots are unused and unimproved
and zoned Light Industrial.

The site is in a mixed commercial and residential area of Wilmington. It bound on the
north by The Longshoreman's Union and residences followed by Kidder Street, on the
east by South 5t" Avenue followed by The Rusty Nail Bar and Maverick America, on the
south by Martin Street and a rail line followed by Shannon's Auto Service, GMC Air
Conditioning and Heating Equipment, and a residence (from west to east), and on the
west by residences and South 7t" Street. Since development in the early 1900's, the
surrounding area has been a mix of industrial, commercial, and residential buildings.
2.2 History of the Property
Parcel 1 of the site was developed first as Wilmington Linen Service circa 1950 and then
was owned by National Linen and affiliated entities until 2011. There were additions to
the laundry facility building in the 1960's and 1970's. Current improvements total about
43,000-sq-ft. Parcels 2 and 3, located to the east of South 6th Street, are wooded and
have been undeveloped since 1915 at the latest.
The property was purchased by Fifth Street Investors, LLC, the current site owner, in
2011 from National Services Industries. During their ownership, there were reportedly no
ongoing laundry operations. The building on Parcel 1 was utilized as a storage space for
Tribute Construction, Inc., a movie set, and as temporary storage space for Mayflower
Transportation. Tribute Construction stored only building materials for residential
construction and Mayflower stored furniture in the building under a short-term lease.
Parcels 2 and 3 remained vacant and unused by Fifth Street Investors, LLC.
The redevelopment of the National Linen site was deemed eligible to participate in the
Brownfields Program on June 30, 2020. Fifth Street Investors, LLC and Raleigh
Restoration Group, LLC are co -Prospective Developers.
The North Carolina Brownfields Program was established under the Brownfields Property
Reuse Act of 1997 [NCGS 130A310.30 et seq.]. This statute authorizes DEQ to work with
prospective developers (provided they did not cause or contribute to site contamination)
to promote the redevelopment of urban infill properties, old industrial sites, and other
types of underutilized, environmentally impaired real estate.

2.3 National Linen Site Redevelopment Plan
October 20, 2020
Page 3
The current redevelopment plan for the site is as commercial brewery and retail food hall.
However, other types of commercial redevelopment options are possible. The
brewery/food hall plan is modeled on the successful re -purposing of the
Stone's Warehouse Brownfields Property (BPN 20044-16-092) in downtown Raleigh.
The co -Prospective Developer will request that residential redevelopment be an
allowed land use under the Brownfields Agreement, notwithstanding that is not the current
plan for the property's reuse.
2.4 Prior Assessment Findinqs
ECS Southeast, LLP (ECS) prepared a Phase I Environmental Site Assessment (ESA)
on June 3, 2019 for the National Linen property. Based on their findings, which included
a summary of earlier work, ECS reported that from 1950 until the 1960's there were two
5,000-gallon heating oil underground storage tanks (USTs) onsite, which were reportedly
replaced with two 10,000-gallon heating oil USTs. There was also one 6,000-gallon
gasoline UST.
One of the 10,000-gallon USTs was reportedly closed in place in 1991 and filled with
sand. The other two USTs were removed in 1993 and received a Notice of No Further
Action (NFA) in 1999 for residual groundwater contamination. Two 10,000-gallon heating
oil aboveground storage tanks (ASTs), which remain on the exterior southeastern side of
the building by the boiler room, were reportedly installed in 1986 and likely taken out of
service circa 2010.
ESC also noted a large out -of -service boiler, miscellaneous drums, tanks, hydraulic lifts,
compressors, and some remnants of equipment from the former laundry operations (e.g.,
overhead piping, duct work, etc.).
Besides the records associated with the USTs and ASTs, the National Linen site is not
otherwise listed as a disposal site, release or environmental incident location by federal,
state, or local authorities.
Based on their Phase I ESA, ECS concluded the following were recognized
environmental conditions (RECs). All RECs were associated with Parcel 1 and the past
use as an industrial laundry.
• A 10,000-gallon closed -in -place UST on the southeastern side of the building
because no formal closure information was available.
• Two out -of -service ASTs, although there was no direct evidence that a release had
occurred from the tanks or ancillary piping systems.
• Interior hydraulic lift remnants, tanks, compressors, and drum storage.
ECS concluded further that these RECs have the potential to impact subsurface
conditions and cause a vapor intrusion concern. ECS recommended additional
assessment but did not specify further. ECS identified no RECs with respect to Parcels 2
and 3. In addition, they identified no offsite incidents or releases expected to result in an
onsite contamination at the National Linen property.

Site Assessment Report October 20, 2020
National Linen Page 4
ECS did not identify the past possible use of National Laundry as a dry-cleaning facility
as an REC, even though dry cleaning was noted on a 1951 Sanborn Fire Insurance Map
(but not on other Sanborn maps nor was this noted elsewhere in the Phase I ESA). In
addition, ECS did not identify the boiler equipment as an REC.
Therefore, in addition to the RECs listed above noted by ECS, we consider the possibility
that the site operated historically as a dry cleaner to be an REC. Also, we consider the
out -of -service boiler and ancillary equipment in the boiler room area to be an REC.
2.5 Data Gaps To Be Filled
At National Linen only limited prior Phase II -type assessment work has been completed
and what was done focused on testing in and around the USTs that were taken out of
service and either removed or, in the case of one tank, closed -in -place. Otherwise, the
other RECs noted above have not been assessed. Therefore, the assessment was
designed to fill data gaps regarding the possible nature and extent of contamination and
other pertinent information, including:
• Possible vapor intrusion risk
• Site -wide soil conditions
• Site -wide groundwater conditions
• Confirmation of groundwater flow direction
• Possible localized impacts where USTs were located, near ASTs and other
equipment, and in the boiler room area
• Possible offsite releases causing onsite contamination
No RECs or other potential concerns were identified associated with the two smaller out -
parcels located to the east of the former laundry facility. Consequently, no assessment
sampling was conducted there.
3 SOIL GAS ASSESSMENT SUMMARY
Aptus retained RDH Environmental Consulting (RDHEC) to complete a soil gas
assessment at National Linen and evaluate possible vapor VI risks. The RDHEC report
is included by reference here and provided in Appendix A.
RDHEC conducted soil gas sampling on September 10, 2020. At total of nine soil gas
samples at eight locations, plus a duplicate sample, were collected, including beneath
the boiler room, and in laundry process areas and storage locations within the building.
The soil gas samples were analyzed by USEPA Method TO-15 for the full analyte list.
A total of 24 analytes were detected. The results were compared to the DEQ's February
2018 list of Non -Residential and Residential VI Soil Gas Screening Levels (SGSLs) and
evaluated further using DEQ's Risk Calculator.
3.1 Non -Residential Site Use and VI Risk
The reported concentrations of detected analytes were well below their respective Non -
Residential SGSLs. In addition, concentrations of the detected analytes was entered into
the DEQ Risk Calculator to determine the Non -Residential Soil Gas to Indoor Air risk.
This showed no unacceptable cancer risk or non -cancer hazard risk.

Site Assessment Report
National Linen
October 20, 2020
Page 5
As a result, RDHEC concluded that no unacceptable VI risks exist, the VI pathway at
the existing building is incomplete, and no further investigation or mitigation is necessary
for commercial redevelopment. Aptus concurs with these findings.
3.2 Residential Site Use and VI Risk
While the current redevelopment plan does not include residential use, residential use
may, nevertheless, be an allowed future land use pursuant to a Brownfields Agreement
entered into by the Prospective Developer and DEQ. Therefore, RDHEC also evaluated
possible VI risk for residential use. For this, they compared the soil gas assessment
results against Residential SGSLs. Only three analytes — chloroform,
dichlorodifluoromethane (Freon 12) and trichloroethylene (TCE) — exceeded their
Residential SGSLs. RDHEC also evaluated possible VI risk for residential use using
the DEQ Risk Calculator to determine the Resident Soil Gas to Indoor Air risk. This
showed acceptable cumulative cancer risk, but the non -cancer hazard risk was greater
than 1.0, primarily from Freon 12 and TCE.
We do not have an explanation for the possible presence of Freon 12, a refrigerant
with no known use at the facility. RDHEC noted that the presence of low-level TCE
(and PCE at levels below the Residential SGSL) could be from possible solvent use or
historical dry-cleaning operations, notwithstanding no indication of gross pollution
conditions were found.
As a result, RDHEC concluded that in the event of future residential site use, which is
not the current redevelopment plan, further assessment of potential VI risks was
warranted. Aptus concurs with these findings.
4 SUMMARY OF SOIL AND GROUNDWATER SAMPLING ACTIVITIES
4.1 Soil Sampling
On September 11, 2020, Tom Proctor of Proctor Environmental Services, Inc. (PES)
conducted the assessment sampling. The site was walked to verify parcel locations,
property boundaries, and proposed sample locations. The soil boring locations were
marked and are shown in Figure 4; photographs of the site can be seen in Appendix B.
A total of seven borings were advanced for soil sample collection using a GeoProbe.
Extracted soil was visually inspected for staining (none was observed) and screened
with a photoionization device (PID) for evidence of VOC emissions. The PID, a MiniRae
3000, Unit Number 21706, was rented from Pine Environmental Services, and calibrated
by a certified technician. A calibration certificate for the unit is provided in Appendix C.
Boring logs summarizing the soil conditions, PID readings, and sample collection
intervals are provided in Appendix D.
PID readings were collected directly from the soil core removed from the boring soon after
collection. As the plastic -encased soil sample cores were removed from the boring, they
were marked for depth -intervals at each end and laid on the ground, on either plastic
sheeting or cardboard. The driller used a GeoProbe razor -knife to slice a small section
from the plastic liner tube so soil could be examined and PID readings collected. The field
technician inserted a field -decontaminated probe rod into the soil sample core at
approximately one -foot intervals to create a hole and subsequently inserted the PID probe

Site Assessment Report October 20, 2020
National Linen Page 6
into the hole to collect a PID reading from the extracted soil. This Kwik-Screening Process
(KSP) allows for numerous PID readings in a short period of time to determine if an
interval of extracted soil exhibits indications of adverse impact without leaving the soil
exposed to atmospheric conditions over an extended period.
Representative portions of the soil were collected into plastic Ziplock baggies, labeled
with the boring number and depth interval, and allowed to equilibrate for approximately
15 minutes before then collecting a "baggie PID reading" by puncturing the baggie and
inserting the PID probe. Finally, a "borehole PID reading" was collected by inserting the
PID probe into the top of the borehole after its completion and after removing the sampling
equipment. PID readings were recorded in the field notes and are summarized below.
The "Borehole PID Reading" column refers to the reading collected by inserting the PID
into the completed borehole after sampling equipment was removed.

Discrete samples were collected for VOC analyses and three-point composite samples
were the collected for SVOCs and metals analysis. Composite samples consisted of the
residual soil left in the vicinity of the VOC sample and then a similar amount of soil
collected approximately one foot deeper and one foot shallower from the VOC sample
interval. The three-part composite samples were placed in a Ziplock baggies, thoroughly
mixed and then immediately placed into the laboratory glassware and placed in an ice -
filled cooler.
Soil samples were transported under chain -of -custody to Waypoint Laboratories in
Charlotte analysis for VOCs by Method 8260B, SVOCs by Method 8270, and RCRA
metals. The two soil samples exhibiting the highest concentration of total chromium, TW-
2S and TW-7S, were also analyzed for Cr6+ by Method 7196A. The laboratory was
instructed that their detection limits should, if possible, be less than the IHSB Preliminary
Soil Remediation Goals (PSRGs).
4.2 Groundwater Sampling
Seven temporary wells were constructed and sampled on September 11, 2020 in
accordance with DEQ procedures in the locations shown in Figure 4.

GeoProbe borings were advanced to approximately five (5) feet below the expected
groundwater depth or 5 to 7 feet bls, and then ten feet of PVC screen and riser pipe were
installed and then backfilled with filter sand and topped with a temporary bentonite seal.
New polyethylene tubing and a peristaltic pump was used to slowly pump groundwater
until the purged water became clearer, then a YSI multiparameter instrument was used
to measure temperature, dissolved oxygen, conductivity, specific conductance, and pH
to verify that representative samples are collected (Table 2).
After developing the wells, groundwater samples were collected beginning with three HCl-
preserved 40-ml vials (for VOC analysis), proceeding to two, one -liter unpreserved glass
bottles (for SVOC analysis), and finishing with one 250-ml HNO3-preserved plastic bottle
for metals analysis. This process resulted in the clearest possible samples for the metals
analysis. Samples were unfiltered. A duplicate QA/QC groundwater sample and a trip
blank for VOC analysis was collected.
The groundwater samples were shipped under chain -of -custody to Waypoint. They were
analyzed for VOCs by Method 8260B, SVOCs by Method 8270, RCRA metals and Cr6+.
The laboratory was instructed that detection limits, if possible, needed to be less than the
NC Groundwater Quality Standards and IHSB residential VISLs.
4.3 Groundwater Elevation Measurements
The location of six of the seven temporary wells (excluding TW-3, which was not needed
to establish groundwater flow direction) were field surveyed relative to a fixed landmark;
the top of casing elevation was surveyed and referenced to an arbitrary datum. The depth
to groundwater was subtracted from the top of casing to determine the static water level
elevation. The survey data and water level measurements are summarized on Tables 4
and 5. Based on survey and depth to groundwater measurements, as shown in Figure 5,
the groundwater flow direction is generally towards the south/southwest, which is
consistent with the area's topography. (Mr. Proctor is not a registered land surveyor and
the field survey was to determine general groundwater flow direction.)

5 SUMMARY OF LABORATORY TEST RESULTS
5.1 Soil Testing Results
The soil laboratory test results are summarized in Table 1 and a copy of the laboratory
report is provided in Appendix E. Most constituents were reported as not detected (i.e.,
below the laboratory detection limits). The few low-level detections measured were well
below PSRGs for both commercial and residential site use. Perhaps most importantly, no
contamination in soil attributable to dry-cleaning solvents was found.
Methylene chloride, a common laboratory relict, was detected at low estimated
concentrations indicated by the "J" flag. Four common SVOCs often found in urban fill
(benzo(a)pyrene, benzo(b)fluoranthene, fluoranthene, and pyrene) were detected in a
single sample from the boring TW-7, but at low estimated concentrations below PSRGs.
Chromium (total) and lead were detected but below PSRGs. Chromium 6+ was reported
as non -detected in the two samples that were analyzed. The detection limit for chromium
6+ was below the commercial PSRG (although slightly above the residential PSRG).
5.2 Groundwater Testina Results
The groundwater analytical results are summarized in Table 3 and a copy of the
laboratory report is provided in Appendix E. No contamination above NC Groundwater
Quality Standards or vapor intrusion screening levels were reported.
The laboratory reported low levels VOCs (chloromethane, chloroform, methylene chloride
and tetrachloroethylene) at "J" estimated values. No TCE was reported above laboratory
detection limits. No SVOCs were reported in any samples above reporting detection
limits. Barium, a natural mineral, was detected but below its groundwater standard.
6 QUALITY ASSURANCE/ QUALITY CONTROL
Standard DEQ quality assurance/quality control (QA/QC) procedures were followed.
Sampling equipment, including the water -level probe, were decontaminated using
Liquinox° detergent and deionized water prior to and between each use. Sampling
personnel wore disposable nitrile gloves. New polyethylene tubing was used at each
groundwater sampling point. Samples were collected into laboratory -provided glassware
or specified containers to ensure sufficient sample volume for analyses. Samples were
shipped overnight by courier to the laboratory in ice -filled coolers under chain -of -custody
protocols.
QA/AC samples were submitted to the laboratory. Specifically, one duplicate groundwater
sample (Dupe-W from TMW-6) and one water trip blank were submitted for VOC analysis.
Neither the duplicate sample nor trip blank had detectable concentrations of VOCs over
laboratory reporting limits. Records of equipment calibration and well gauging, purging,
and sampling data were maintained by field personnel at each sample location.
The laboratory analytical reports, chain -of -custody records and field notes were evaluated
to ensure that the reported results are valid, accurate and sufficient to meet quality
objectives. Accuracy has been evaluated through reviewing laboratory -spiked recoveries
and precision has been evaluated through the assessment of duplicate results.

7 INVESTIGATION DERIVED WASTE MANAGEMENT
The small quantities of groundwater and soil IDW generated during sampling was placed
back into the boring or spread around the boring location as no indications of adverse
impacts were encountered.
8 SUMMARY OF FINDINGS AND RECOMMENDATIONS
8.1 Assessment Findings
This report provides the assessment finding for soil gas, soil, and groundwater testing.
Samples were collected from across the property and intended to address data gaps and
provide information on possible RECs at National Linen. The assessment was also
intended to help guide due diligence, identify the land use restrictions and mitigation
measures needed to safely redevelop the property, and provide suitable information for
a Brownfields Agreement that the Prospective Developer intends to enter into with DEQ.
As discussed above and summarized in more detail below, only limited, low-level
contamination was found at National Linen. Soil and groundwater had no measurable
contamination above DEQ standards or guidelines applicable to both commercial and
residential site use. Soil gas testing showed no unacceptable VI risk for commercial
redevelopment of the property, which is the intended plan for National Linen. For
residential site use, which is not the current redevelopment plan, further assessment of
potential VI risks should be conducted.
8.1.1 Soil Gas Testing and VI Risks
Low-level contamination was reported in soil gas samples, but below Non -Residential
SGSLs. RDHEC concluded that no unacceptable VI risks exist, and no further
investigation or mitigation is necessary for commercial redevelopment. For possible,
residential site use, which is not the current redevelopment plan, further assessment of
potential VI risks should be conducted. Aptus concurs with these findings.
8.1.2 Soil Testing
No VOCs, SVOCs or metals were detected in soil at concentrations that exceeded their
most stringent regulatory guidelines, which depending on the analyte, is either the IHSB
residential health -based or protection of groundwater PSRGs. Most constituents tested
were reported as non -detected.
Based on these assessment findings, there were no VOCs, SVOCs or metal
contaminants in soil that are expected to pose an unacceptable risk for redevelopment of
the National Linen site.
8.1.3 Groundwater Testing
No VOCs, SVOCs or metals were detected in groundwater at concentrations above their
NC Groundwater Quality Standards or DEQ vapor intrusion screening levels for
residential and commercial site use. Most analytes were reported as non -detected.
Only four VOCs (chloromethane, methylene chloride, chloroform and tetrachloroethylene)
were reported as being detected in groundwater. In each case, they were reported as
estimated concentrations, as indicated by the "J" flags in the laboratory report. None of

Site Assessment Report October 20, 2020
National Linen Page 10
the estimated levels of these analytes exceeded their North Carolina Groundwater Quality
Standards or vapor intrusion screening levels.
Also based on the groundwater test results, there does not appear to be onsite
contamination at National Linen that originated from offsite upgradient sources. The most
upgradient well, TW-2, located at the northeast corner of the site, was contaminant -free
and the other onsite wells, including those with low-level impacts, do not appear to be
impacted by a possible offsite source.
8.2 Recommendations Regarding RECs and Data Gaps
Among other objectives of this assessment, as discussed above, the work was intended
to provide information to fill certain data gaps, help direct safe redevelopment of the
National Linen property and for the site Brownfields Agreement.
8.2.1 Possible Vapor Intrusion Risk
No unacceptable VI risks appear to exist for commercial use and, therefore, no further VI
investigation or mitigation is recommended for that development scenario. For possible
residential site use, which is not the current redevelopment plan, further assessment of
potential VI risks is warranted, but only if residential development is planned.
8.2.2 Site -Wide Soil Conditions
Across the site, no VOCs, SVOCs or metals were detected in soil at concentrations that
exceeded their most stringent regulatory guidelines, which depending on the analyte, is
either the IHSB residential health -based or protection of groundwater PSRGs. Most
constituents tested were reported as non -detected. Therefore, no further investigation of
soil conditions is recommended.
8.2.3 Site -Wide Groundwater Conditions
Across the site, no VOCs, SVOCs or metals were detected in groundwater at
concentrations above their NC Groundwater Quality Standards or DEQ vapor intrusion
screening levels for residential and commercial site use. Most analytes were reported as
non -detected. Therefore, no further investigation of groundwater conditions is
recommended.
8.2.4 Confirmation of Groundwater Flow Direction
Groundwater flow is generally to the southwest following the area topography. No further
assessment of groundwater flow direction is recommended.
8.2.5 Possible Localized Impacts
The assessment included soil, groundwater and soil gas sampling throughout the site
including near where USTs were located, the remaining ASTs and other equipment, and
in the boiler room area.
Like our findings on the site -wide conditions, virtually no contamination was found in soil
and groundwater attributable to possible localized onsite sources. Therefore, no further
investigation of soil or groundwater conditions is recommended with respect to possible
onsite sources.

8.2.6 Possible Offsite Releases
October 20, 2020
Page 11
Based on the groundwater test results, there does not appear to be onsite contamination
at National Linen that originated from an offsite upgradient source. The most upgradient
well, TW-2, located at the northeast corner of the site, was contaminant -free and the other
onsite wells, including those with low-level impacts, do not appear to be contaminated by
possible offsite sources. Therefore, no further investigation of possible offsite upgradient
contaminant sources is recommended.

NCBP PROJECT NO. 24028-20-065
RDHEC PROJECT NO. 1907.00
Dear Mr. Gallagher:
RDH Environmental Consulting (RDHEC) is pleased to provide the enclosed report for the vapor intrusion
(VI) sampling that was conducted at the above -referenced site on September 10, 2020. The project was
performed in accordance with the terms and conditions of RDHEC Proposal No. P2992 dated August 29,
2020, which was authorized by your email on this date.
The VI assessment was comprehensive and targeted locations throughout the former laundry facility. The
work was completed in general accordance with current NC Brownfields Program VI guidance. The
assessment indicated low-level detections of 24 contaminants when analyzed for the full -list of EPA
Method TO-15 laboratory analytes. Comparisons of the maximum detected sample concentrations to the
February 2018 North Carolina VI screening levels for soil gas at commercial properties, as well as via the
NCDEQ Risk Calculator, showed no unacceptable VI risk exists for commercial use of the site.
Consequently, it is RDHEC's opinion that no further assessment or mitigation is warranted.
When the results were compared to the more stringent screening levels for residential use, the
maximum detections of three contaminants were found to exceed their screening levels. While the
redevelopment plans are currently for commercial purposes, further assessment of potential VI risks
should be conducted should redevelopment plans change to residential site use.
If you have any questions regarding the report or associated documentation, please feel free to contact
me at [phone] at your convenience.

1.0 EXECUTIVE SUMMARY
Pursuant to NC Brownfields Program (NCBP) Project No: 24028-20-065, RDHEC conducted
vapor intrusion (VI) sampling on September 10, 2020 at the former National Linen site located
at 1315 South 51" Avenue in Wilmington, New Hanover County, North Carolina (see Drawing 1—
Site Location Map, Drawing 2 — Topographical Site Map, and Drawing 3 — Site Map with Parcel
Overlays, attached). The sampling was performed to provide the North Carolina Division of
Environmental Quality (NCDEQ) Division of Waste Management (NCDWM) Brownfields
Program an assessment of VI conditions prior to development of the site. Current plans are to
repurpose the site to commercial use as a brewery and restaurant.
The project involved installation of sub -slab probes (Vapor Pins) in the existing concrete slab to
evaluate soil gas beneath various segments of the floor plan (boiler room, laundry process
areas, and storage locations). Testing was conducted later the same day, after allowing each
probe location to equilibrate for at least two hours. The sampling involved collection of nine (9)
soil gas canister samples across eight (8) locations in the building footprint (one of the
locations, SG-5, included a duplicate sample), in accordance with DWM VI guidance. Table 1
summarizes the canister sampling details, including boring/slab specifics, shut-in test vacuum,
and pre- and post -sampling leak check observations for each location tested. The soil gas
sampling locations are shown in Drawing 4. Photographs from the sampling are referenced in
Appendix A.
The results of the laboratory EPA Method TO-15 analyses were compared to the NCDEQ's
February 2018 list of Non -Residential and Residential VI Soil Gas Screening Levels (NRSGSLs and
RSGSLs, attached in Appendices B and C, respectively) following receipt of the laboratory report
(Appendix D). A total of 24 analytes were detected across the nine analyses.
Non -Residential Site Use and VI Risk
The concentrations of each detected analyte were well below the respective NRSGSLs (three
detected analytes had no NRSGSL). These results are provided in Table 2 (attached). In addition,
concentrations of each of the detected analytes was entered into the NCDEQ Risk Calculator to
determine the Non -Residential Soil Gas to Indoor Air risk (see Appendix E). This showed both
acceptable cumulative cancer risk and non -cancer hazard risk.
These VI testing results, coupled with the recent soil and groundwater site assessment by
Proctor Environmental Services (PES), indicate that no unacceptable VI risks exist, the VI
pathway at the existing building is incomplete, and no further investigation or mitigation is
necessary for commercial redevelopment.

Residential Site Use and VI Risk
October 12, 2020

While the current redevelopment plan does not include residential use, residential use may,
nevertheless, be an allowed future land use pursuant to a Brownfields Agreement entered into
with the prospective developer and DEQ. Therefore, we evaluated possible VI risk for
residential use.
For this, we compared the VI assessment results against RSGSLs — see Table 3. Three analytes —
chloroform, dichlorodifluoromethane (Freon 12) and trichloroethylene (TCE) — exceeded their
RSGSLs. These results are provided on Drawing 5 for reference. After discounting the presence
of chloroform as a VI contaminant (due to chlorinated municipal water use), concentrations of
detected analytes were entered into the NCDEQ Risk Calculator to determine the Resident Soil
Gas to Indoor Air risk (see Appendix Q. This showed acceptable cumulative cancer risk but a
non- cancer hazard risk greater than 1.0, primarily from Freon 12 and TCE.
We do not have an explanation for the possible presence of Freon 12, a refrigerant not known
to have been used at the facility. The presence of low-level TCE (and PCE at levels below the
RSGSL) could be from possible historical use of the site as a dry cleaner facility.
In the event of future residential site use, which is not the current redevelopment plan,
RDHEC recommends further assessment of potential VI risks.
2.0 INTRODUCTION
The site is comprised of three parcels across approximately 2.58 acres zoned for urban mixed -
use redevelopment. One of the parcels (1315 S 5th Avenue) is a paved lot occupied by an
approximately 43,000 square foot building, which is currently vacant. The other two eastern
parcels across S 6th Street consist of wooded, undeveloped land.
Aptus requested PES to perform soil and groundwater sampling, and RDHEC to conduct sub -slab
soil gas sampling to assess site conditions. This report summarizes RDHEC's VI testing, including
sampling, laboratory results and conclusions.
3.0 TESTING SUMMARY
Sampling Probe Locations/Placement (9/10/2020)
Shortly after arrival at 10:30 am, the probe/sampling point locations were marked and
documented using a measuring wheel. A portable generator provided power for a hammer drill
that was used to bore 5/8-inch holes in the concrete slab. Vapor Pins fitted with silicone sleeves
were secured into each boring using a special tool and rubber hammer, then capped. The building
has concrete floor slabs throughout. Each of the probes were placed into the concrete floor and
compacted sands were found beneath each boring location. Additional details regarding boring

depth and slab thickness are provided in Table 1. The eight sample locations are shown to scale
on Drawing 4. Following completion of installation at 2:30 pm, the probe locations were left to
equilibrate for two hours prior to sampling.
Meteorological conditions from the time of probe placement through sampling included clear/
partly cloudy skies and slight winds with periodic gusts from 5 to 10 mph. Temperatures ranged from
80 °F at the time of arrival to a high of 90 °F in the afternoon (average 81.6 °F), with relative humidity
ranging from 77 to 99% (average 92%). These data are from a nearby personal weather station
(station ID Historic Downtown Wilmington - KNCWILM1158) located approximately 1.1 miles north-
northwest of the site on Castle Street. According to the weather station, barometric pressure was
nearly constant, ranging between 30.08 to 30.16 inches during the testing (average 30.12 inches).
The last rain event at the site occurred two days prior to the testing date (0.68 inches on Tuesday,
September 8t"). Thus, there was no significant precipitation within 12 hours prior to (or during) the
sampling event to induce pressure gradients that might affect soil V1.
Sampling (9/10/2020)
RDHEC began the sampling later that afternoon at 4:30 pm at the boiler room location. Sampling
continued until 8 pm.
The samples were collected using 1/4-inch rigid Teflon tubing and 1-L Summa canisters. Small 1-
to 2-inch pieces of 1/4-inch and 3/8- inch silicone tubing were employed to make connections to
the various valves and fittings of the sampling trains. Tubing was connected to the barbed fittings
of the Vapor Pins, routed through a plastic shroud (which was placed over each probe site) and
the opposite ends connected to 3-way valves and 60-milliliter (mQ syringes to form a sampling
train for each probe location.
Shut-in tests were performed to ensure air tight conditions at each location. Once the sampling
train was deemed leak -free, the probe tubing was purged of three dead volumes using a 60-mL
syringe and leak checked while the shroud was filled with helium. With 2.0 feet of 1/4-Inch tubing
(inner diameter of 0.177 inches), three dead volumes equaled 29 mL. (Note — 120 to 180 mLs
were slowly purged using the syringe to allow for sufficient volume for the helium leak check,
described below).
The helium concentrations within the shroud were measured and noted using a MGD-2002 leak
detector. The purged soil gas was collected into a 0.5-L Tedlar bag via the 3-way valve. After
purging, the Tedlar bag was removed and the contents monitored for helium levels. A successful
leak check was deemed when the purged soil gas contained less than 10% of the initial shroud
concentration of helium. Each of the purged helium concentrations were between 0 and 150 ppm
(0.02%). Therefore leak -free conditions were achieved and no adjustments were necessary.
Each of soil gas samples was collected using 1-L canisters fitted with 15- to 30-min flow
regulators. The SG-5 sample location employed an inline tee and a single flow regulator to collect

a duplicate sample for quality assurance purposes, in accordance with Brownfields Program
guidance, for a total of nine (9) soil gas samples/analyses across eight (8) sample locations.
Following completion of the sampling, post -sampling leak checks were performed again at each
location using helium. After a successful post -sampling leak check, the probe tubing and Vapor
Pins were removed from each location and the probe borings were sealed with grout. Quality
assurance results (shut-in test vacuum levels and pre- and post -testing leak check shroud and
purge helium concentrations) are included in Table 1.
Laboratory analysis request forms were then completed for laboratory analysis using EPA
Compendium Method TO-15 "Determination of Volatile Organic Compounds (VOCs) in Air
Collected in Specially -Prepared Canisters and Analyzed by Gas Chromatography/Mass
Spectrometry (GC/MS)" and the canisters were placed back in the laboratory packaging for return
shipment. The full -list of TO-15 analytes was requested for low-level analysis. Since post -
sampling leak checks were conducted, helium analysis by the laboratory was not required.
Samples were taken to FeclEx the next day for shipment under proper chain of custody.
4.0 SOIL GAS SAMPLING RESULTS
Laboratory results for the soil gas analyses are summarized in Table 2, attached. Of the 24 analytes
that resulted in detectable quantities, three (3) of the compounds did not have a listed
NRSGSL. The levels for the detected compounds were compared to the current (February 2018)
table of the NCDWM non-resident soil gas screening levels (NRSGSLs) for sub -slab and exterior
soil gas VI at commercial sites. None of the analytes exceeded its respective NRSGSL. Each
concentration was minimal and well below the corresponding NRSGSL for the contaminants,
ranging from 0.003% to 26.1% of the respective screening levels. Fifteen (15) of the 21 analytes
with a screening level were less than 1% of the NRSGSL.
Although none of the detected analytes exceeded commercial NRSGSLs, a risk analysis
was performed using the DEQ Risk Calculator.
The guidance for soil gas data evaluation and screening states, "If soil gas concentrations do
NOT EXCEED the SGSLs, typically no further investigation is necessary and the VI pathway may
be considered incomplete if the investigator is confident in the CSM and the data collected are
adequate to evaluate the VI pathway. The SGSLs are expected to be conservative due to a
generic default attenuation factor."
The soil and groundwater assessment results provided by Proctor Environmental Services
(PES) showed almost no contamination in subsurface soil or groundwater. This also
suggests site conditions will pose no unacceptable VI risk. The PES soil samples indicated no
VOC concerns, and what was detected was well below the NC Preliminary Soil Remediation
Goals (PSRGs).

No groundwater samples collected under the building footprint showed impacts. One
groundwater sample presented low-level J-Flag hits for chloromethanes and PCE outside
the southwest corner of the building. PCE measured at this location was 0.27 ug/L, which is
below the 15A NCAC 02L .0202 groundwater quality standard of 0.7 ug/L
Residential Site Use and VI Risk
While the current redevelopment plan does not include residential use, residential use may,
nevertheless, be an allowed future land use pursuant to a Brownfields Agreement entered into with
the prospective developer and DEQ. Therefore, we evaluated possible VI risk for residential use.
For this, we compared the VI assessment results against residential soil gas screening levels (RSGSLs)
— see Table 3. Three analytes — chloroform, dichlorodifluoromethane (Freon 12) and
trichloroethylene (TCE) — exceeded their RSGSLs. These results are provided on Drawing 5 for
reference. After discounting the presence of chloroform as a VI contaminant (due to chlorinated
municipal water use), concentrations of detected analytes were entered into the NCDEQ Risk
Calculator to determine the Resident Soil Gas to Indoor Air risk (see Appendix Q. This showed
acceptable cumulative cancer risk but a non -cancer hazard risk greater than 1.0, primarily from
Freon 12 and TCE.
We do not have an explanation for the possible presence of Freon 12, a refrigerant not known to
have been used at the facility. The presence of low-level TCE (and PCE also at low levels) could be
from possible historical use of the site as a dry cleaner facility.
In the event of future residential site use, which is not the current redevelopment plan, further
assessment of VI risks should be considered.
5.0 CONCLUSIONS/RECOMMENDATIONS
Based on the prior Phase I ESAs, the known concerns at the National Linen site are from onsite
petroleum releases, none of which resulted in onsite groundwater contamination based on soil and
groundwater sampling conducted by PES on September 11, 2020. Additionally, dry cleaning may
have been conducted based on a 1951 Sanborn map that showed "Dry Cleaning" at the site,
although two Phase I reports did not cite dry cleaning as a recognized environmental concern (REC).
The results from this soil gas investigation show that sub -slab soil gas concentrations are below
NCDWM SGSLs for non-residential use (i.e., minimal VI risk since the levels of site COCs were less
than 27% of the NRSGSLs). Similarly, a risk analysis was also performed using the DEQ Risk Calculator
showed no unacceptable VI risks for commercial site use.
On this basis, it is RDHEC's opinion that no unacceptable VI risk exists for commercial use and no
further assessment or mitigation is warranted.

If the site is to be used for residential purposes, there may be a risk of VI due to cumulative hazards
of non -carcinogens primarily associated with Freon 12 and TCE (see Table 3 and Drawing S).
In the event of future residential site use, which is not the current redevelopment plan, further
assessment of potential VI risks should be conducted.
