Dear Bill:

1.0 Introduction

Hart & Hickman, PC (H&H) is providing this Annual Redevelopment Summary Report for the
Caraustar and Savona Mills Brownfields property (Brownfields Project No. 23061-19-060)
located at the intersection of South Turner Street and Chamberlain Avenue in Charlotte,
Mecklenburg County, North Carolina (Site). The Site is comprised of six contiguous parcels
(Parcel Identification Nos. 07111209, 07111410, 07111412, 07111418, 07111419, and
07111417) that collectively total approximately 25 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, and a Site map is provided as Figure 2.

Northern portions of the Site along Chamberlain Avenue are developed with an approximately
9,500 square foot (sq ft) industrial building (410 S. Gardner Avenue) and an approximately
31,000 sq ft industrial warehouse building. The 401 S. Gardner Avenue Site parcel is located in

mill/redevelopment report/2023/final to deq/23057 - caraustar and savona mills_annual redevelopment summary report_2024.doc
the northeastern portion of the Site and is developed with an approximately 4,500 sq ft office
building. The eastern portion of the Site along South Turner Avenue is developed with an
approximately 186,000 sq ft former mill building which has recently been renovated for multi-
tenant commercial/retail uses.

Redevelopment at the Site is ongoing and has included the demolition of select former Site
buildings and leveling the Site for redevelopment Phase I which includes construction of three
multi-family residential apartment buildings, one for-rent townhome building, and associated
parking areas as described in the North Carolina Department of Environmental Quality (DEQ)
approved Environmental Management Plan (EMP) dated May 10, 2021. Note, that this report
does not address redevelopment activities associated with the existing mill building located in
the eastern portion of the Site. Redevelopment activities associated with the mill building were
documented in a Redevelopment Completion & Final Grade Soil Assessment Report dated
November 21, 2023. An overlay of the proposed redevelopment is shown in Figure 3, and a
copy of the Site Plan prepared by Kimley Horn depicting the proposed redevelopment is
provided as Appendix A.

According to the DEQ-approved EMP, a report of environment-related activities will be
prepared and submitted to DEQ Brownfields each year for as long as physical redevelopment of
the Brownfields property continues. Redevelopment activities at the Site began in March 2022,
and the first Annual Redevelopment Summary Report prepared for the Site was submitted to
DEQ on January 26, 2023. This report has been prepared to document redevelopment activities
completed in 2023. A brief summary of the annual redevelopment activities is provided in the
following sections.

2.0 Environmental-Related Redevelopment Activities

Redevelopment activities at the Site have been conducted in general accordance with the DEQ-
approved EMP. Redevelopment activities at the Site are ongoing and have included mass
grading, installation of subsurface utilities, construction of high-density residential apartment

buildings and associated parking areas, and installation of vapor intrusion mitigation system
(VIMS) components as part of new building construction. A brief summary of soil management
and VIMS installation activities is provided below.

2.1 Soil Management

Redevelopment activities completed at the Site in 2023 have included Site grading activities,
installation of subsurface utilities, and foundation and vertical construction of the multi-family
apartment buildings for Phase I of redevelopment (Building 1 through Building 4).
Redevelopment activities resulted in excess soil that is planned for re-use on Site during Phase II
redevelopment activities. Excess soil planned for use during future phases of construction will
be managed following the DEQ-approved EMP. Redevelopment activities completed in 2023
did not include importing soil to the Site.

In 2023, renovations for adaptive reuse of the mill building included the installation of new sub-
surface utilities. Utility installation activities generated excess soil from the right-of-way along
S. Turner Avenue which was transported to northern portions of the Site for use during limited
grading activities for a new sidewalk along Chamberlain Avenue right-of-way. H&H was
notified that the relocated soil had resulted in a minor encroachment of approximately 45 sq ft
onto the 410 S. Gardner Avenue portion of the Brownfields property at the Chamberlain Avenue
and S. Gardner Avenue intersection. The approximate extent of the right-of-way soil
encroachment area is shown in Figure 3.

Out of an abundance of caution, H&H conducted shallow in situ soil characterization sampling
to evaluate the potential for impacts in the limited volume of fill soil placed on the Brownfields
property at the Chamberlain Avenue and S. Gardner Avenue intersection. H&H collected five
aliquot soil samples from approximately 0 to 0.5 ft below ground surface (ft bgs) within the soil
encroachment area which is the estimated depth of fill placed on the Brownfields property at the
intersection. Soil samples were logged for lithologic description, inspected for the presence of
visual and olfactory indications of potential impacts, and screened for the presence of volatile
organic vapors with a calibrated photoionization detected (PID). The results of field screening

mill/redevelopment report/2023/final to deq/23057 - caraustar and savona mills_annual redevelopment summary report_2024.doc
activities did not identify obvious evidence of impacts within the soil samples collected from the
placed fill.

Soil sample aliquots were homogenized to form one composite soil sample (COMP-1)
representative of soil inadvertently placed on the Brownfields property (Figure 3). The
composite soil sample selected for laboratory analysis was collected directly into dedicated
laboratory supplied containers, labeled with the date, time, and sample identification, and placed
in a laboratory supplied sample cooler with ice. The sample was submitted to Waypoint
Analytical (Waypoint), a North Carolina certified laboratory, under standard chain of custody
protocols for analysis of semi-volatile organic compounds (SVOCs) by EPA Method 8270 and
Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium by EPA
Methods 6020/7471/7199. In addition, one representative grab soil sample was collected from
an undisturbed portion of soil that was not used for field screening. The grab soil sample was
submitted to Waypoint for analysis of volatile organic compounds (VOCs) by EPA Method
8260. A copy of the laboratory analytical report is provided as Appendix B, and a summary of
the analytical results is provided in Table 1.

Laboratory analytical results identified select polynuclear aromatic hydrocarbons (PAHs)
including benzo(a)anthracene (1.45 J milligrams per kilogram [mg/kg]), benzo(a)pyrene (3.09
mg/kg), benzo(b)fluoranthene (3.27 mg/kg), and indeno(1,2,3-cd)pyrene (2.18 mg/kg) at
concentrations above their respective DEQ Protection of Groundwater and/or Residential
Preliminary Soil Remediation Goals (PSRGs). No other organic compounds were detected at
concentrations above the DEQ PSRGs. Several metals were detected at concentrations
consistent with naturally occurring levels and are considered to be representative of background
conditions at the Site.

The DEQ PSRGs are very conservative and are 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. DEQ and EPA acceptable soil direct exposure risks include a calculated

mill/redevelopment report/2023/final to deq/23057 - caraustar and savona mills_annual redevelopment summary report_2024.doc
cumulative lifetime incremental carcinogenic risk (LICR) of 1 x 10-4 or less and a calculated
cumulative hazard index (HI) of 1.0 or less for potential non-carcinogenic risks.

H&H utilized the DEQ Risk Calculator (July 2023) under a residential, non-residential,
construction worker, and trespasser land use to further evaluate potential cumulative risks for the
soil direct exposure pathway. Risk calculator results indicate that cumulative carcinogenic and
non-carcinogenic risks are below the DEQ and EPA acceptable levels for the residential, non-
residential, construction worker, and trespasser exposure scenarios. Risk calculator results are
summarized in Table 1, and copies of the completed risk calculators are provided in Appendix C.

2.2 Vapor Mitigation System Installation

As part of the construction of the multi-family residential buildings, select components of the
VIMS have been installed following the DEQ-approved Vapor Intrusion Mitigation Plan (VIMP)
dated July 26, 2022. H&H completed inspection activities during various phases of VIMS
installation to verify that the system was installed in general accordance with the DEQ-approved
VIMP.

For quality assurance and quality control purposes, H&H personnel, under the direction of the
VIMS design engineer, completed inspections after the placement of each of the VIMS
components in each building installed thus far (sub-slab horizontal soil gas collection network,
vapor barrier, and select riser conveyance piping). Based on the results of the inspections, the
VIMS installation is on-going and is being installed following the DEQ-approved VIMP. Details
associated with VIMS installation activities will be documented in reports that will be submitted
to DEQ under separate cover.

3.0 Summary

In summary, redevelopment activities at the Caraustar and Savona Mills Brownfields property
are ongoing and are being conducted in general accordance with the DEQ-approved EMP. In

addition, vapor intrusion mitigation system installation activities are on-going in accordance with
the DEQ-approved VIMP.

Upon completion of construction activities and installation of impervious surfaces in exterior
areas surrounding the Site buildings, H&H will observe the Site for unpaved areas. Based on
observations, H&H will prepare a work plan outlining a proposed final grade soil sampling
approach for DEQ Brownfields review and approval. In addition to final grade soil sampling,
following completion of the VIMS installation activities, H&H will prepare VIMS Installation
Completion Reports for each building for submittal to DEQ.

QC Batch No: L707915/L707346 The matrix spike and/or the matrix spike duplicate was outside quality control acceptance ranges. A post
digestion spike was performed and passed quality control acceptance ranges. No matrix interference is suspected.
Sample 95419 (CSS-4)
Analyte: Barium QC Batch No: L707915/L707346
The matrix spike, matrix spike duplicate and the dilution test were all outside of the quality control acceptance ranges. Matrix interference is suspected.
Sample 95419 (CSS-4)
Analyte: Chromium QC Batch No: L707915/L707346
The matrix spike, matrix spike duplicate and the dilution test were all outside of the quality control acceptance ranges. Matrix interference is suspected.
Sample 95419 (CSS-4) Analyte: Lead QC Batch No: L707915/L707346
The matrix spike, matrix spike duplicate and the dilution test were all outside of the quality control acceptance ranges. Matrix interference is suspected.
Hexavalent Chromium by Ion Chromatography Method SW-7199 Sample 95976 (FG-4) Analyte: Hexavalent Chromium QC Batch No: L708430/L707678 Matrix Spike Recovery Low: A measure of the sample pH and its oxidation reduction potential (ORP) indicate that
the sample has reducing qualities which may not allow for the presence of Hexavalent Chromium. Solids Total Mercury Analysis - CVAA Method 7471B Sample 95748 Analyte: Mercury QC Batch No: V38344/V38283 The matrix spike, matrix spike duplicate and the post digestion spike were all outside of the quality control acceptance ranges. Matrix interference is suspected

Page 5 of 33

Recovery for the LCS exceeded the upper acceptance limit. However, all sample results associated with the
batch are below the MQL, so this high bias had no impact upon the client data. The results are considered to be acceptable.
Analyte: Benzoic Acid
QC Batch No: V38347/V38274 Analyte was flagged for 0% recovery in the LCS and LCSD due to the result being below the MQL. The actual
result was 13.979 and 14.565 respectively, which calculates to a recovery of 27.958% and 29.13% which is within the acceptable recovery range.
