H&H Job No. POR-001

1.0 Introduction

On behalf of Savona II LLC, Savona LLC, and 410SG Partners, LLC (collectively the
Prospective Developer or PD), Hart & Hickman, PC (H&H) has prepared this report to
document additional Brownfields assessment activities conducted at the Caraustar and Savona
Mills Brownfields property (Brownfields Project No. 23061-19-060) located at the
intersection of South Turner Avenue and Chamberlain Avenue in Charlotte, Mecklenburg
County, North Carolina (Site). The Site is comprised of nine contiguous parcels (Parcel ID
Nos. 07111209, 07111412, 07111410, 07111418, 07111417, 07110551, 07110552,
07110501, and 7110503) that collectively total approximately 30.8 acres of land located in a
rapidly densifying area of the Seversville neighborhood less than one mile northwest of
uptown Charlotte. A Site location map is provided as Figure 1.

Northern portions of the Site along Chamberlain Avenue are developed with an approximately
14,500 square foot (sq ft) industrial warehouse building (2426 Chamberlain Avenue), an
approximately 22,500 sq ft industrial warehouse building (2425 Chamberlain Avenue), an
approximately 9,500 sq ft light manufacturing building (410 S. Gardner Avenue), and an
approximately 31,000 sq ft industrial warehouse building and an approximately 4,500 sq ft
office building (401 S. Gardner Avenue). The eastern portion of the Site along S. Turner
Avenue is developed with an approximately 186,000 sq ft former mill building. Remaining
portions of the Site consist of undeveloped vacant land except for foundations of former mill
buildings, paved access roads. and paved parking areas. The Site and surrounding area are
shown on Figure 2.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
1.1 Site Background Information

Savona Manufacturing Company
The eastern portion of the Site was developed with the southern portion of the main Savona Mill
building by 1915. The central portion of the Savona Mill building was constructed as an
addition in 1921 for yarn spinning operations. The Savona Mill building was utilized as a textile
mill from the 1910s until the 1930s. Additional structures located at the Site were utilized for
mill purposes and included a filter house, a bleaching and finishing building, warehouses, and a
285,000-gallon water reservoir. Textile production operations at the Site ceased by the mid-
1930s.

Old Dominion Box Company – 401 and 411 South Gardener Avenue
In 1935, Old Dominion Box Company (Old Dominion) began manufacturing boxes and
paperboard products in the former Savona Mill building. Operations were expanded in the mid-
1950s, when Old Dominion constructed a three-story paper warehouse at the northern end of the
Savona Mill building and several buildings near the intersection of Chamberlain Avenue and
Gardner Avenue (currently 401 and 411 South Gardner Avenue). Based on information
provided in available historical sources, Old Dominion continued operations at the Site until the
late-1980s or mid-1990s.

Carolina Paperboard Corporation / Caraustar Corporation
In the 1940s, Carolina Paperboard Corporation constructed a paperboard manufacturing facility
northwest of the Old Dominion operation. The Carolina Paperboard facility included a pulp mill,
offices, finishing room, machine shop, settling basin, and other ancillary structures. Information
provided in the environmental documents prepared for the Site indicates Carolina Paperboard
operated one 3,000-gallon underground gasoline storage tank (UST), one 2,000-gallon diesel
UST, one 4,000-gallon diesel UST, one 10,000-gallon diesel UST, and six 30,000-gallon fuel oil
USTs that were installed in the north-central portion of the Site between 1968 and 1982.
According to information provided in an Underground Storage Tank Closure Report, Carolina
Paper Board, 443 S. Gardner Street, Charlotte, NC, prepared by SPATCO Environmental dated
February 26, 1993, six 30,000-gallon fuel oil USTs, one 6,000-gallon magnesium chloride above

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
ground storage tank (AST), and one 4,000-gallon sulfuric acid AST were removed from the Site
in February 1993. Information related to closure of the remaining reported USTs is not
available.

By the 1980s, Carolina Paperboard merged with Caraustar Industries, Inc. (Caraustar). Paper
manufacturing operations continued at the Site until the 2010s. Limited recycling and storage
operations continued until the mid-2010s. Between 2000 and 2010, buildings and ancillary
structures located in the southern and central portions of the Site were razed. Remaining
Caraustar buildings include the former paper storage building located at 2425 Chamberlain
Avenue and the former paperboard processing building located at 2426 Chamberlain Avenue.

Wikoff Color – 410 South Gardner Avenue
The former Wikoff Color facility is located southwest of the intersection of Chamberlain Avenue
and S. Gardner Avenue at 410 South Gardner Avenue. Based on information provided in
environmental documents prepared for the Site, the facility historically manufactured inks
utilized for printing of food packaging products from 1965 until 2015. Wikoff Color previously
generated ignitable hazardous wastes as part of its operations. Based on review of previous
environmental documents, multiple waste management compliance violations were reported in
connection with the Wikoff Color facility in the 1980s and 1990s. Wikoff Color ceased
operations at the Site in 2015.

Parcels East of South Turner Avenue
Based upon review of available historical aerial photographs, the parcels located east of South
Turner Avenue were developed with ancillary structures and single-family residences as early as
the late 1930s. By the late 1940s, parking areas associated with Savona Mill were developed on
the Site east of S. Turner Avenue. The eastern Site parcels have primarily been utilized for
trailer storage and parking areas since the 1980s. One single-family residence remains at 524
State Street.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
1.2 Brownfields Program

To address potential environmental concerns associated with historical on-Site and nearby off-
Site operations, Savona II, LLC elected to enter the Site into the North Carolina Department of
Environmental Quality (DEQ) Brownfields Program and received eligibility in a letter dated
January 14, 2020 and an amended letter of eligibility dated January 13, 2022, which includes
Savona II, LLC, Savona LLC and 410SG Partners, LLC as joint Prospective Developers and
added the 410 S. Gardner Avenue parcel (PIN 07111410) to the Brownfields property and
removed the 532 State Street parcel (PIN 07110502) from the Brownfields property.

In the Brownfields Program, the Prospective Developer (as defined by the Brownfields statutes)
of a property and DEQ enter into an agreement which provides for State liability protection for
cleanup of identified soil, groundwater, or other impacts in exchange for making the Site safe for
its future intended use. Making the Site safe for its intended use is typically accomplished by
implementing land use restrictions (i.e., restriction on groundwater usage) and engineering
controls (such as capping impacted soil) and not through remediation.

Provided that the Site is developed in accordance with the Brownfields agreement, the
developer receives State liability protection for impacts identified at the Site. This liability
protection also applies to any future owner of the property, occupants of the facility, a successor
or assign, and any lender or fiduciary (provided they are not otherwise potentially responsible
parties). Impacts at the Site are being evaluated under by the DEQ Brownfields Program and
will be addressed through the implementation of land use restrictions in the pending
Brownfields agreement.

Planned redevelopment includes renovation for adaptive re-use of select existing Site buildings
and construction of new multi-family residential buildings and parking decks in undeveloped
portions of the Site. The proposed Site plan is shown on Figure 2.

An Environmental Management Plan (Rev 1) prepared for the proposed redevelopment was
approved by the DEQ Brownfields Program on June 24, 2021. H&H understands that the DEQ

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
Brownfields Program expressed concerns associated with certain previous assessment activities
completed at the Site and requested additional sampling be completed. To address DEQ
Brownfields Program requests for additional assessment, H&H prepared a Comprehensive Data
Summary and Additional Brownfields Assessment Work Plan (Work Plan), dated March 9,
2022, for DEQ review and approval. The Work Plan received DEQ-approval in an email dated
March 28, 2022.

The additional Brownfields assessment activities discussed in the following sections include
collection of soil, exterior soil gas, and sub-slab soil gas samples. A summary of the additional
Brownfields assessment activities conducted in accordance with the DEQ-approved Work Plan is
provided in the following sections.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
2.0 Additional Brownfields Assessment Activities

Brownfields assessment activities were completed in April 2022 and included collection of soil,
sub-slab soil gas, and exterior soil gas samples to further evaluate the potential for impacts
associated with historical on-Site operations.

As part of the additional assessment activities, soil borings were advanced in the area northwest
of the former Wikoff Color buildings to further delineate metals impacts in shallow soil. In
addition, soil and exterior soil gas samples were collected adjacent to a daycare facility located
adjacent to the northern Site boundary to evaluate the potential for impacts from former on-Site
operations to migrate off-Site to the north. To evaluate the potential for structural vapor
intrusion into previously unassessed Site buildings, H&H collected sub-slab soil gas samples
within the 401 and 411 South Gardner Avenue buildings.

Prior to conducting field activities, H&H contacted North Carolina 811, the public utility locator,
to mark subsurface utilities at the Site. H&H also contracted with a private utility locator to
mark utilities at the Site which were not identified by the public locator. In addition, H&H
directed the drilling contractor to hand clear each boring to approximately 5 ft bgs to further
screen the boring locations for the presence of subsurface utilities.

The assessment activities were performed in general accordance with the DEQ IHSB Guidelines
for Assessment and Cleanup of Contaminated Sites (Guidelines) dated July 2021, the DEQ
Division of Waste Management (DWM) Vapor Intrusion Guidance (VI Guidance) dated March
2018, most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV
Science and Ecosystem Support Division (LSASD) Field Branches Quality System and
Technical Procedures guidance, and the DEQ-approved Work Plan.

A summary of the soil and soil gas assessment activities are provided in Section 3.0 and Section
4.0, respectively. A description of the quality assurance and quality control measures are
provided in Section 5.0, and summary and conclusions based on results of the assessment
activities are provided in Section 6.0.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -

3.0 Soil Assessment Activities

In April 2022, Mid-South Environmental (Mid-South) advanced two (2) soil borings HH-SB-01
and HH-SB-02) along the northern Site boundary to evlaute the potential for impacts nearest the
north adjacent daycare facility, and eight (8) soil borings (HH-SB-03 through HH-SB-10) to
further delineate metals impacts in soil near the loading dock area of the Wikoff Color building.
Locations of the soil borings are shown in Figure 3.

Soil borings were advanced utilizing a decontaminated stainless-steel hand auger or a
track-mounted direct push technology (DPT) drill rig. During boring advancement, continuous
soil samples were collected from the center of the hand auger bucket or from acetate lined
macrocore DPT sampling sleeves. The soil samples were logged for lithologic description,
observed for obvious evidence of staining and unusual odors, and field screened for the presence
of volatile organic vapors using a calibrated photoionization detector (PID). Obvious evidence
of staining or odor and elevated PID readings were not observed by field personnel during soil
boring advancement. In addition to use of the PID for field screening, H&H utilized calibrated
Vanta M RK Analyzer to collect x-ray fluorescence (XRF) measurements for chromium and lead
concentrations in samples collected from borings advanced in the Wickoff Color loading dock.
Boring logs including lithologic descriptions and field screening results for each soil boring are
provided in Appendix A.

A discussion of the soil sampling activities and results is provided in the following sections.

3.1 Soil Sampling Activities

Adjacent Daycare Facility
Two soil borings (HH-SB-01 and HH-SB-02) were advanced to approximately 2 ft bgs in a
vegetated area at the Site south of the north adjacent daycare facility located at 318 and 322
South Gardner Avenue. As discussed above, field screening results did not identify evidence of
potential impacts during boring advancement. Therefore, soil samples were collected for
laboratory analysis from shallow soil (i.e., no greater than 2 ft bgs) at each soil boring in

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
accordance with the DEQ-approved Work Plan.

Soil samples selected for laboratory analysis 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 samples were subsequently delivered to
Pace Analytical (Pace) under standard chain of custody protocols for laboratory analysis of
VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Methods
6020/7471, and hexavalent chromium by EPA Method 7199.

Former Wikoff Color Property
One soil boring (HH-SB-03) was advanced to approximately 5 ft bgs in the vicinity of former
soil boring 2021-SB-01 located near the northwestern corner of the former Wikoff Color
building to evaluate the vertical extent of chromium, barium, and lead concentrations detected
during previous assessment activities completed by others. In addition, seven (7) “step-out” soil
borings (HH-SB-04 through HH-SB-10) were advanced to approximately 5-6 ft bgs in the
cardinal directions on each side of former soil sample 2021-SB-01. Note that only one step-out
boring (HH-SB-07) could be advanced south of the central HH-SB-03 soil boring due to the
presence of the Site building.

As noted above, H&H conducted soil assessment at the Wikoff Color property utilizing a XRF
analyzer. An XRF analyzer is a portable hand-held device that can provide in-situ quantitative
measurements of metal concentrations in soil. The XRF analyzer was utilized to define the
vertical and lateral extent of lead and chromium impacts in the vicinity of former soil boring
2021-SB-01. The soil assessment utilizing the XRF analyzer was conducted in general
accordance with the US EPA LSASD Operating Procedure for Field X-Ray Fluorescence
Measurement dated February 2, 2022.

Based upon XRF field observations, one soil sample was collected from each boring for
laboratory analysis from the depth interval blow the highest field screening results to confirm the
lateral and vertical extents of metals impacts. A tabular summary of the XRF soil field screening
data is provided as Table 1.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
The soil samples selected for laboratory analysis 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 samples were delivered to Pace under
standard chain of custody protocols for laboratory analysis. One soil sample was collected from
the 0-1 ft bgs depth interval from soil sample HH-SB-03, and submitted for analysis of RCRA
metals by EPA Methods 6020/7471 and hexavalent chromium by EPA Method 7199, and RCRA
metals using the toxicity characteristic leachate procedure (TCLP) by EPA Methods 6010/7471.
A vertical delineation soil sample was collected from soil boring HH-SB-03 at 3-4 ft bgs and
submitted to Pace for analysis of RCRA metals and hexavalent chromium by EPA Methods
6020/7471/7199 and TCLP RCRA metals by EPA Methods 6010/7471.

Lateral delineation borings HH-SB-04 through HH-SB-10 were submitted for analysis of RCRA
metals and hexavalent chromium by EPA Methods 6020/7471/7199 and TCLP RCRA metals by
EPA Methods 6010/7471. Soil samples collected from delineation borings HH-SB-08 through
HH-SB-10 were placed on hold pending analytical results from soil borings HH-SB-04 through
HH-SB-07. Based on laboratory analytical results for soil samples HH-SB-04 through HH-SB-
07, samples HH-SB-08, HH-SB-09, and HH-SB-10 were not analyzed.

Following sampling activities, the soil borings were properly abandoned with hydrated bentonite
chips, and the surfaces were repaired similar to pre-drilling conditions. Additionally, the soil
sample locations were estimated using a hand-held global positioning system (GPS) unit.

3.2 Soil Sampling Analytical Results

The laboratory analytical results were compared to the most recent versions of the DEQ
Preliminary Soil Remediation Goals (PSRGs) dated January 2022. In addition to the DEQ
PSRGs, H&H utilized background metals data obtained from Elements in North American Soils
by Dragun and Chekiri (2005) for comparison to regional naturally occurring levels of metals in
soil. A tabular summary of the soil sample analytical results is presented in Table 2. The
laboratory analytical reports and chain of custody records are provided in Appendix B.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
A discussion of the laboratory analytical results in comparison to the regulatory screening levels
is included below.

3.2.1 Adjacent Daycare Facility

Organic Compounds
Laboratory analytical results indicated that no organic compounds were detected at
concentrations above the laboratory method detection limits in the HH-SB-01 soil samples.
Results of the HH-SB-02 soil sample identified the presence of the polynuclear aromatic
hydrocarbon (PAH) benzo(a)pyrene (0.202 J milligrams per kilogram [mg/kg]) at an estimated
concentration above the DEQ Residential PSRG of 0.11 mg/kg. The “J-Flag” designation
indicates the compound was detected at a concentration above the laboratory method detection
limit, but below the laboratory reporting limit resulting in a laboratory estimated concentration.
No other organic compounds were detected at concentrations above the DEQ Residential PSRGs
in the HH-SB-02 soil sample, and no compounds were detected at concentrations above the DEQ
Industrial/Commercial PSRGs.

Metals
As expected, several metals were detected at concentrations above laboratory method detection
limits in the soil samples collected at the Site. The concentrations of metals detected were
generally consistent with published background levels for regional soil and are considered to be
representative of naturally occurring conditions.

Direct Contact Risk Evaluation
The DEQ PSRGs used for comparison to the laboratory analytical results are conservative and
based upon a Target Cancer Risk (TCR) of 1 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 cumulative lifetime incremental cancer risk
(LICR) of 1 x 10-4 or less, and the acceptable level for non-carcinogenic risks is a cumulative
Hazard Index (HI) of 1 or less.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
Although the laboratory analytical results did not indicate compound concentrations above the
Residential PSRGs, with the exception of benzo(a)pyrene and naturally occurring levels of
metals, H&H utilized the DEQ Risk Calculator (January 2022) to further evaluate potential direct
contact risks at unacceptable levels under hypothetical “worst-case” residential, non-residential,
construction worker, and trespasser use scenarios for soil samples collected adjacent to the
daycare facility. To model a hypothetical worst-case scenario, H&H input the highest
concentration of each compound detected in the soil samples collected adjacent to the off-Site
daycare facility into the DEQ Risk Calculator. A copy of the completed DEQ Risk Calculator is
provided in Appendix D. The Risk Calculator results are discussed further below.

Evaluation Area Land Use Cumulative LICR Cumulative HI Unacceptable
Levels?
Adjacent to Off-
Site Daycare
Facility
Residential 1.2 x 10-5 0.23 No
Non-Residential 2.2 x 10-6 0.017 No
Const. Worker 3.7 x 10-7 0.018 No
Trespasser 6.4 x 10-6 0.13 No

As shown in the table above, DEQ Risk Calculator results confirm that there is no direct contact
exposure pathway in Site soil near the off-Site daycare facility based on the soil sample
laboratory analytical results.

3.2.2 Former Wikoff Color Building

As shown in Table 1, laboratory analytical results identified the presence of several metals at
concentrations above laboratory method detection limits in the soil samples collected near 2021-
SB-01 where elevated levels of metals were previously identified by others. Laboratory
analytical results identified hexavalent chromium (up to 34.1 mg/kg) at concentrations exceeding
the DEQ Residential and Industrial/Commercial PSRGs in the shallow and deeper HH-SB-03
soil samples. Hexavalent chromium was also detected at concentrations exceeding the DEQ
Residential PSRG, but below the DEQ IHSB Industrial/Commercial PSRGs, in samples HH-SB-
05 (3.74 mg/kg), HH-SB-06 (1.55 mg/kg), and HH-SB-07 (2.32 mg/kg). Remaining metals

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
concentrations (including lead, barium, and chromium) were detected at concentrations
consistent with published background levels for regional soil and are considered to be
representative of naturally occurring conditions.

The results of the TCLP analysis indicate the presence of lead, barium, chromium, and selenium
in the leachate at a concentration above the laboratory method detection limits, but well below
the EPA Maximum Concentrations for TCLP. Therefore, based on the analytical data, metals do
not appear to be present at characteristically hazardous levels in shallow soil located in the
loading dock area of the former Wickoff Color Site building.

Based on laboratory analytical results, elevated concentrations of metals detected in previously
collected soil sample 2021-SB-01 appear to primarily related to hexavalent chromium, are
limited in lateral and vertical extent, and appear to be isolated to the area nearest the loading
dock of the former Wickoff Color building.

4.0 Soil Gas Sampling Activities

To further evaluate the potential for structural vapor intrusion, H&H collected seven (7) sub-slab
soil gas samples (HH-SSV-01 through HH-SSV-07) within the existing Site buildings located at
401 and 411 South Gardner Avenue. To evaluate the potential for impacts at the Site to migrate
onto off-Site properties located to the north of the Site, two (2) temporary exterior soil gas
sampling points (HH-SG-01 and HH-SG-02) were installed and sampled adjacent to the north
adjacent off-Site daycare facility. The locations of the temporary sub-slab and exterior soil gas
sampling points are shown on Figure 3, and are described further below:

 three (3) sub-slab soil gas samples (HH-SSV-01 through HH-SV-03) were collected in
the western portion of the 401 South Gardner Avenue building,
 two (2) sub-slab soil gas samples (HH-SSV-04 and HH-SSV-05) were collected in
eastern portion of the 401 South Gardner Avenue building,
 two (2) sub-slab soil gas samples (HH-SSV-06 and HH-SSV-07) were collected in the
411 South Gardner Avenue building; and
 two (2) exterior soil gas samples (HH-SG-01 and HH-SG-02) were collected near the
northern Site boundary adjacent to an off-Site daycare facility.

4.1 Soil Gas Sampling Activities

Exterior Soil Gas Sample Point Installation
Under the direction of H&H, Mid-South advanced two (2) soil borings for installation of
temporary exterior soil gas sampling points (HH-SG-01 and HH-SG-02) in the northern portion
of the Site (Figure 3).

Each soil gas sampling point boring was advanced to approximately 5.5 ft bgs using a stainless-
steel hand auger. Continuous soil samples were collected from the soil gas monitoring point
borings and logged for lithologic description, observed for obvious evidence of staining and
unusual odors, and field screened for the presence of volatile organic vapors using a calibrated
PID. Field screening results did not indicate obvious evidence of potential impacts in the soil

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
gas sampling point borings.

Once at target depth, a six-inch stainless steel vapor implant screen attached to a length of
Teflon® tubing was installed at the base of each borehole. Filter sand was then placed within the
annulus of the boring from the base of the boring to a depth of approximately 6-inches above the
top of the vapor screen. The sampling points were completed by placing hydrated bentonite
from the top of the filter sand to the ground surface. Boring logs including lithologic
descriptions, field screening results, and soil gas monitoring point construction details are
provided in Appendix A.

Sub-Slab Soil Gas Sample Point Installation
H&H installed seven (7) sub-slab soil gas sampling points (HH-SSV-01 through HH-SV-07)
within the existing the South Gardner Avenue Site buildings. Prior to installation activities,
H&H inspected the buildings to confirm that no basements or crawl spaces were present. The
sub-slab soil gas sample locations are shown on Figure 3.

The sub-slab soil gas sampling points were installed using a rotary hammer drill and 1½-inch
diameter drill bit to advance a pilot hole into the concrete slab to a depth of approximately 1¾
inches below the surface. A drill guide was then placed in the pilot hole and a 5/8-inch diameter
drill bit was utilized to advance the boring through the concrete slab and approximately 6-inches
into the underlying soil. Following concrete borehole advancement, loose concrete cuttings were
removed from each boring using a bottlebrush. A Cox-Colvin Vapor Pin™ (vapor pin) assembly
(brass sampling point and silicone sleeve) was then seated in the borehole using an
installation/extraction tool and hammer. Upon installation of the vapor pin assembly, dedicated
Teflon® sample tubing was connected to the barbed end of the sample point.

Exterior and Sub-Slab Soil Gas Sampling
Each exterior and sub-slab soil gas sample was collected utilizing a laboratory supplied 1-liter
Summa® canister connected to an air-flow regulator calibrated by the laboratory to collect the
soil gas sample at a rate of approximately 100 ml/min. Prior to collection of the soil gas
samples, “shut-in” tests were conducted on the sampling train and helium leak checks were

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
conducted at each soil gas sampling point. A description of the shut-in test and helium leak
testing procedures is provided 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 occurs. If the vacuum reading
remained the same, the shut-in test was considered successful. If vacuum loss occurs, the flow
regulator and/or brass cap was reseated and the shut-in test was repeated until the vacuum
reading remained stable.

Following the shut-in test, the Summa® canister was connected to the sample point via Teflon®
sample tubing using a brass nut and ferrule assembly to create an air tight seal and the leak check
was performed. The leak check was performed by constructing a shroud over the sampling train
and flooding the shroud with helium gas. Helium concentrations inside the shroud were
measured using a helium gas detector and maintained at concentrations ranging from
approximately 14.3% to 21.2%. Once helium concentrations stabilized within the shroud, the
sample tubing was purged outside of the shroud using a syringe and a three-way valve to collect
purged soil gas into a Tedlar® bag. The purged soil gas was then analyzed using the helium gas
detector to ensure that helium concentrations in the soil gas sample were less than 10% of the
helium concentrations measured within the shroud. Each soil gas sampling point was purged of
a minimum of three sample train volumes and each soil gas sampling point passed the helium
leak check criteria.

Following successful leak checks, the soil gas samples were collected by opening the intake
valve on the Summa® canister. Vacuum readings on the Summa® canister were recorded prior to
and following the sampling period to ensure adequate sample volume was collected. A vacuum
of approximately 5 inches of mercury or more were maintained within the canisters at the
conclusion of the sampling event in accordance with DEQ DWM guidance. Following sample
collection, the Summa® canisters were shipped to Pace under standard chain-of-custody

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
protocols for analysis of VOCs by EPA Method TO-15. Upon receipt of the samples, the
laboratory recorded the final received vacuum pressure for each Summa® canister.

After sampling was completed, the sample locations were estimated by measuring from known
benchmarks within the Site building or using a hand-held GPS unit or measured from known
benchmarks within the building (e.g., doors, windows, exterior walls, etc.). The sample
locations were properly abandoned and the surfaces were repaired similar to pre-drilling
conditions.

4.2 Soil Gas Sampling Results

Laboratory analytical results for the soil gas samples were compared to the DEQ DWM
Residential and Non-Residential Vapor Intrusion Sub-Slab and Exterior Soil Gas Screening
Levels (SGSLs) dated January 2022. A summary of the analytical results is provided as Table 3,
and the laboratory analytical data report and chain of custody record is included as Appendix B.

Laboratory analytical results indicate the presence of compounds at concentrations above the
laboratory reporting limits in each sample, but below the DEQ DWM Vapor Intrusion SGSLs
with the exception of ethylbenzene (61.9 µg/m3), hexachloro-1,3-butadiene (8.5 J µg/m3), and
naphthalene (up to 5.5 J µg/m3) which were detected at concentrations exceeding the DEQ
DWM Vapor Intrusion Residential SGSLs in sub-slab soil gas samples collected in the South
Gardner Avenue Site buildings. No other constituents were detected at concentrations exceeding
the DEQ DWM SGSLs in the sub-slab soil gas samples, and no compounds were detected at
concentrations above the DEQ DWM SGSLs in the exterior soil gas samples collected near the
northern Site boundary.

4.3 Vapor Intrusion Evaluation

DEQ DWM Vapor Intrusion SGSLs are conservative and based upon a Target Cancer Risk
(TCR) of 1 x 10-6 for potential carcinogenic effects and a Target Hazard Quotient (THQ) of 0.2
for potential non-carcinogenic effects. Vapor intrusion mitigation or additional assessment is not

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
typically warranted if the calculated cumulative LICR is 1 x 10-4 or less and the acceptable level
for non-carcinogenic risk is a HI of 1.0 or less.

H&H utilized the DEQ Risk Calculator (January 2022) assuming a residential land use scenario
to further evaluate potential cumulative risks for the soil gas to indoor air vapor intrusion
pathway for the soil gas samples collected in the northern portion of the Site nearest the adjacent
off-Site daycare facility including a soil gas sample (2021-SV-02) collected by others in 2021
(see Table 3 for summary of previous 2021-SV-02 soil gas data). H&H utilized the DEQ Risk
Calculator (January 2022) assuming a non-residential land use scenario to further evaluate
potential cumulative risks for the soil gas to indoor air vapor intrusion pathway for the soil gas
samples collected in South Gardner buildings which is proposed for renovations and reuse for
commercial purposes.

H&H calculated the cumulative risks using the highest concentration of any compound detected
in any soil gas sample collected within the South Garnder buildings and adjacent to the daycare
facility at the Site to model potential vapor intrusion risk under a hypothetical “worst-case”
scenario. Risk calculator results are summarized in the table below. Copies of the completed risk
calculators are provided in Appendix D.

As shown in the table above, results of hypothetical worst-case residential use scenario risk
calculator results confirm that there are no cumulative carcinogenic or noncarcinogenic vapor
intrusion risks at unacceptable levels for the soil gas to indoor air pathway using soil gas data
collected nearest the adjacent off-Site daycare facility. Additionally, hypothetical worst-case
non-residential use scenario risk calculator results confirm that there are no cumulative
carcinogenic or noncarcinogenic vapor intrusion risks at unacceptable levels for the soil gas to
indoor air pathway using soil gas data collected within the S. Gardner Street Site buildings.

5.0 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. Field QA/QC samples were analyzed along with the investigative samples to determine
potential variability introduced in sampling, handling, shipping, and analysis. H&H collected
duplicate soil and soil gas samples to evaluate the ability of the laboratory to reproduce sample
results.

5.1 Field Duplicates

Duplicate samples were collected to evaluate the precision of the field sampling procedures,
sample matrix variability, and analytical reproducibility. Duplicate soil samples were collected
directly into individual laboratory supplied sample containers using sampling methodologies
described in previous sections. The duplicate soil gas sample was collected concurrently with
the parent sample using a laboratory supplied T-fitting which allows for collection of two soil
gas samples from one soil gas sampling point simultaneously. The samples were analyzed for
the same parameters as the parent samples, 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 (Table 2 for soil and Table 3 for soil gas). Review of the duplicate sample
results for the soil and soil gas samples did not indicate significant variability compared with the
results of the parent samples. Laboratory analytical results can be found in Appendix B.

6.0 Summary and Conclusions

H&H completed additional Brownfields assessment activities at the Caraustar and Savona Mills
Brownfields property located at the intersection of South Turner Street and Chamberlain Avenue
in Charlotte, North Carolina. The assessment activities were conducted in general accordance
with the DEQ Brownfields Work Plan dated March 9, 2022. Brownfields assessment activities
included collection of soil and soil gas samples for laboratory analysis to further evaluate
potential risks associated with the Site and to assist in management of Site media during future
redevelopment activities. A brief summary of the Brownfields assessment activities is provided
below.

 Results of soil assessment activities completed in the northern portion of the Site nearest
the north adjacent off-Site daycare facility identified the PAH benzo(a)pyrene at a
concentration slightly above the DEQ Residential PSRG in the HH-SB-02 soil sample.
No other organic compounds were detected at concentrations exceeding the DEQ PSRGs.
Metals concentrations detected in soil samples collected in the northern portion of the
Site are consistent with published background levels and are considered to be
representative of naturally occurring conditions.

 DEQ Risk Calculator results confirm that there is no direct contact exposure pathway in
Site soil near the off-Site daycare facility based on the soil sample laboratory analytical
results.

 Results of soil assessment activities completed near the former Wikoff Color building
identified hexavalent chromium at concentrations above the DEQ Residential and
Industrial/Commercial PSRG in the shallow and deeper soil sample collected in the
location of the previous 2021-SB-01 soil sample where elevated concentrations of metals
were identified by others. Lower levels of hexavalent chromium were detected at
concentrations above the Residential PSRG in three of the four delineating step-out soil
samples. Remaining metals concentrations detected in soil samples collected north of the
Wickoff Color Site building are consistent with published background levels and are

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
considered representative of naturally occurring conditions. Soil assessment results
indicate that metal impact previously identified on the northern side of the Wickoff Color
building appear to be associated with hexavalent chromium and is limited in lateral and
vertical extent to the area of the loading dock.

 The results of the TCLP analysis for soil samples collected in the Wickoff Color loading
dock area did not indicate the presence of metals in the leachate at a concentration above
the EPA Maximum Concentrations for TCLP. Based on the analytical data, metals do
not appear to be present at characteristically hazardous levels in shallow soils in the area
of the previous 2021-SB-01 soil sample.

 Results of the soil gas assessment activities completed within the 401 and 411 South
Garnder Avenue buildings identified low levels of ethylbenzene, hexachloro-1,3-
butadiene, and naphthalene at concentrations above the DEQ DWM Residential Vapor
Intrusion SGSLs. Hypothetical worst-case non-residential use (based on the planned
commercial use of the buildings) risk calculator results indicate that the cumulative LICR
is 5.1 x 10-7 for potential carcinogenic risks and the cumulative HI is 0.030 using soil gas
data collected within the S. Gardner Street Site buildings. Based on results of the soil gas
sampling activities completed within the S. Gardner Street Site buildings the cumulative
carcinogenic and noncarcinogenic vapor intrusion risks are below the DEQ and EPA
acceptable levels and there does not appear to be a risk for vapor intrusion at
unacceptable levels into the existing Site buildings.

 No compounds were detected at concentrations above the DEQ DWM Vapor Intrusion
SGSLs in the exterior soil gas samples collected in near the northern Site boundary.
Hypothetical worst-case residential use risk calculator results indicate that the cumulative
LICR is 2.0 x 10-6 for potential carcinogenic risks and the cumulative HI is 0.17 using
soil gas data collected near the adjacent off-Site daycare facility. Based on results of the
soil gas assessment activities, there is no indication that impacts at the Site are migrating
toward the north in the direction of the adjacent off-Site day care facility.

s:\aaa-master projects\portman holdings\caraustar & savona mill\additional brownfields assessment\report\23061 -
additional brownfields assessment report - caraustar and savona mills.doc
In summary, results of additional soil assessment activities indicate impacts in the vicinity of the
daycare facility are generally limited to low levels of PAHs, which are ubiquitous on industrial
use properties and in urban areas and not necessarily an indication of a release of hazardous
materials. Results of soil sampling activities at the former Wikoff Color property identified
hexavalent chromium at concentrations above the DEQ PSRGs. Soil in the vicinity of the
daycare and the former Wikoff Color buildings can be managed in accordance with the
Brownfields approved Environmental Management Plan (EMP), and no further soil sampling in
these areas appears to be warranted.

Based on sub-slab soil gas analytical results, there is no indication of a significant VOC source
beneath the 401 and 411 South Gardner Avenue Site buildings that would pose a vapor intrusion
risk at unacceptable levels. Based on sub-slab soil gas analytical results and cumulative worst-
case risk calculations, there does not appear to be a potential risk for structural vapor intrusion
into the Site buildings, and no further sampling in this portion of the Site appears to be
warranted. In addition, results of soil gas samples collected near the northern Site boundary
confirm impacts at the Site are not migrating to the north toward off-Site properties and no
further sampling in this portion of the Site appears to be warranted.

H&H understands that potential vapor intrusion risks will be managed through proactive
installation of a DEQ Brownfields Program approved passive vapor intrusion mitigation system
during construction of the proposed residential buildings. Based on results of assessment
activities completed at the Site to date, there are no unacceptable risks of potential vapor
intrusion into existing Site buildings planned for adaptive re-use, and no vapor mitigation or
post-construction, pre-occupancy sampling appears to be warranted.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
