GASTONIA, GASTON COUNTY, NORTH CAROLINA
Brownfields Project Number 25031-21-036
1.0 INTRODUCTION
1.1 Site Location, Address, and Acreage
The Wix Filtration II Brownfields property is located at 1301 & 135 East Ozark Avenue within the
city limits of Gastonia, Gaston County, North Carolina (Figure 1). The Site is comprised of two
vacant parcels of commercial land encompassing approximately 4.51 acres and currently
contains the concrete footings, slabs, and a portion of a building associated with the former Wix
Filtration property (1301 East Ozark Avenue) and an existing commercial building (former Henry
Yarns property) located at 1315 East Ozark Avenue (Figure 2). Preliminary redevelopment plans
include upgraded entrance/exit from Ozark Avenue, asphalt -paved parking areas, and ground
level commercial and retail space with multi -family residential space above. A generalized
representation of the preliminary redevelopment footprint is depicted on Figure 3.
1.2 Site History
Previous environmental site assessment activities have been conducted at the former Wix
Filtration and former Henry Yarns properties by GTA and others. Currently, the former Wix
Filtration property is regulated by NCDEQ Inactive Hazardous Sites Branch (IHSB) and
Underground Storage Tank (UST) Section. The former Henry Yarns property is not currently
regulated by NCDEQ or other regulatory agencies.
GTA reviewed the following reports prepared by others for the former Wix Filtration property:
• October 2012 — WSP Environment and Energy (WSP) Phase 1 Environmental Site
Assessment (ESA) - Wix Filtration Corporation - Ozark Plant - 1301 East Ozark Avenue
Gastonia, North Carolina
• November 2012 — WSP Phase II ESA - Wix Filtration Corporation — Ozark Plant — Gastonia,
North Carolina
• February 2013 — WSP Notification of an Inactive Hazardous Substance or Waste Disposal
Site
• June 2020 — Harmon Environmental, PA - Phase I ESA - Former Wix Filtration Facility -1301
East Ozark Avenue Gastonia, North Carolina
A summary of previous environmental assessment activities is provided below.
WSP conducted a Phase I ESA of the former Wix Filtration property in October 2012, and
indicated that the property was initially developed in the 1880s as a cotton mill to produce yarn
and thread out of bailed cotton fiber. Operations included carding, combing, twisting, and

NCDEQ 25031-21-036 Wix Filtration II
March 22 2023 GTA Protect No. 31211876
spinning cotton fibers. Wix Filtration purchased the site in the late 1930s and reportedly began
automotive filter production operations from the basement of the of the cotton mill using cotton
mill waste as filter media. Sometime in the 1950s Wix Filtration built a second structure and
discontinued cotton mill operations to focus on automotive filter production. Two additional
buildings were added in the 1960s and 1970s, and automotive filter production operations,
including sheet metal cutting, stamping, brazing, polishing, paper cutting and pleating, testing,
packaging, and shipping continued until December 2011. At the time of WSP's Phase I ESA, the
former Wix Filtration property was vacant and used for warehousing only.
WSP identified the following RECs during their assessment activities:
• Layer of ash or cinders present under basement floorboards of the "Old Building".
• Presence of abandoned two hydraulic lift shafts filled with sand and nearby approximate
100 square foot -stained area.
• Potential septic or cesspit based on historical industrial use.
Additionally, WSP indicated that two 10,000-gallon USTs located southwest side of the property
between "Old Building" built in the 1880s and the "New Building" built in the 1950s were closed
in place on July 31, 2000. The lack of additional information regarding the USTs was considered
a historical REC.
WSP conducted a Phase II ESA to evaluate the RECs identified above. The Phase II ESA included
the collection of surface soil, subsurface soil, and groundwater samples for analysis. Based on the
analytical data, WSP concluded that soil beneath the former Wix Filtration property was
impacted with concentrations of polycyclic aromatic hydrocarbons (PAHs), metals, and
tetrachloroethylene (PCE) that exceeded regulatory standards (Figure 4). Additionally, WSP
concluded that shallow groundwater was not impacted with PAHs, metals, or volatile organic
compounds (VOCs).
Based on the findings of the November 2012 Phase II ESA, WSP sent a Notification of an Inactive
Hazardous Substance or Waste Disposal Site to NCDEQ's IHSB on behalf of Wix Filtration
Corporation. The notification indicated that soil at the former Wix Filtration property was
impacted with concentrations of PCE, PAHs, and metals that exceeded regulatory screening
levels. No additional information regarding the regulatory status of the former Wix Filtration
property was available.
Between 2013 and 2014, a majority of the former Wix Filtration site buildings were demolished,
leaving only concrete slabs, footings, and one approximate 7,500 square foot building, similar to
existing site conditions.
On June 11, 2020, Harmon Environmental conducted a Phase I ESA for the former Wix Filtration
property and identified RECs similar to those noted in the WSP Phase I ESA (stained soil, historical
detections of PAHs, PCE, and metals, and the presence of two closed in place 10,000-gallon USTs).
Harmon Environmental, PA does not appear to have conducted any additional environmental
assessment activities at the former Wix Filtration property.
On April 25, 2022, GTA conducted a Phase I ESA of the former Henry Yarns property at 1315 East
2

NCDEQ 25031-21-036 Wix Filtration II
March 22 2023 GTA Protect No. 31211876
Ozark Avenue, which contained a warehouse building for a former yarn and dyeing facility. The
site building was attached to the former Wix Filtration site until it was detached in the late 1930s.
GTA indicated that the following RECs were associated with the former Henry Yarns property:
• Long-term use as a textile mill for yarn production and dyeing operations dating back to
at least 1914.
• Evidence of dye waste products discharge to an exterior separator pit and underground
cistern.
• A suspected UST located on the northeastern exterior of the subject property.
• The lack of historical information prior to development with the current building by 1914.
• A former railroad spur located on the subject property from prior to 1922 until at least
1970.
• Impacted soil at the former Wix Filtration property located adjacently southwest to the
former Henry Yarns property.
On October 25, 2021, AAT, LLC applied to NCDEQ's Brownfields Program as a prospective
developer seeking a Brownfields Agreement (BFA) at the former Wix Filtration property located
at 1301 East Ozark Avenue. On December 2, 2021, NCDEQ determined the property was eligible
for entry into the Brownfields Program and for continued evaluation for a BFA.
A Conceptual Site Plan provided by AAT, LLC dated October 13, 2022 indicated that potential site
redevelopment plans included two mixed -use buildings (Building A and Building B) to be
constructed on the subject property. Conceptual uses for Building A included approximately
40,000 to 50,000 square feet of ground floor commercial, retail, and lobby space with
approximately 260 micro apartment units constructed on floors 2 through 5. Conceptual uses for
Building B included approximately 100,000 square feet of ground floor commercial self -storage
space with approximately 176 micro apartment units constructed on floors 2 though 5.
On January 31, 2023, on behalf of AAT, LLC, Moore & VanAllen (MVA) submitted an amendment
to the Brownfields Property Application (BPA) to include the adjoining parcel located at 1315 East
Ozark and to enter the "Redevelopment Now" option. On April 4, 2023, NCDEQ determined that
the project was eligible for entry into the Brownfields Program and for continued evaluation
pursuant to a BFA.
On May 2, 2023, AAT, LLC, MVA, and GTA met with NCDEQ to discuss the subject property
background, historical environmental assessment and investigation information, and proposed
path forward. NCDEQ requested a Data Gap Assessment Work Plan, a draft of which was
submitted on July 6, 2023. Based on NCDEQ feedback, the sampling scope was revised and is
described in the following sections.
1.3 Data Gap Assessment
On August 16, 2023, GTA's Data Gap Assessment Work Plan was approved by NCDEQ project
manager Carolyn Minnich. The plan called for soil, groundwater, and soil vapor investigations
across the subject property, as summarized by Table 1. Sampling efforts focused on areas of
3

NCDEQ 25031-21-036 Wix Filtration II
March 22 2023 GTA Proiect No. 31211876
historical usage with potential for impacts and areas located within the proposed redevelopment
footprint. The soil samples taken during the completion of the assessment were sent to the lab
for analysis of RCRA Metals, VOCs, and SVOCs, but were not speciated for hexavalent chromium
at the time. Additionally, groundwater was not sampled for hexavalent chromium in the initial
sampling event. This work plan is being submitted to the NCDEQto address the lack of hexavalent
chromium results from the initial work plan for continued evaluation in the Brownfields Program.
2.0 SCOPE OF WORK
Based on the site history and summary of potential data gaps presented above, GTA has prepared
this Data Gap Assessment Work Plan in general accordance with NCDEQ Brownfields
Redevelopment Sections Minimum Requirements Checklist for Site Assessment Work Plans and
Reports dated March 2023. A detailed summary of the proposed scope of work is presented in
the following sections.
2.1 Media Sampling
Based on the historical property uses, presence of impacted soil on the former Wix Filtration
property, and lack of analytical data on the former Henry Yarns property, GTA initially proposed
the collection of surface and subsurface soil, groundwater, and soil vapor samples as summarized
below and in Table 1.
Sampling efforts of this work plan will focus on areas evaluated during the prior sampling that
had elevated levels of total chromium, as well as areas that lack sufficient data coverage.
Proposed media sampling locations are shown on Figure 5.

3.0 SAMPLING METHODOLOGY
3.1 Soil Sampling
Collection of surface soil samples will be conducted in general accordance with NCDEQ Inactive
Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites
dated September 2022, which includes guidance for soil remediation goals, naturally occurring
background levels, sampling techniques, and quality assurance. Analytical data for surface and
subsurface soil samples will be compared to NCDEQ's residential health -based Preliminary Soil
Remediation Goals (PSRGs) dated February 2024.
3.1.1 Surface Soil
Grab surface soil samples will be collected from approximately 0.0-1.0 and 1.0-2.0 feet below
ground surface using a decontaminated stainless steel hand auger (proposed locations on Figure
5) and transferred into laboratory provided sample containers, transferred to a chilled cooler
with ice and forwarded to a North Carolina certified analytical laboratory under chain of custody
protocol for hexavalent chromium analysis under USEPA method 7199 (Table 1).
4.0 LABORATORY ANALYSIS
Surface soil samples will be submitted for laboratory analysis based on field observations. A
summary of the analytical program for this assessment is summarized below.

**One duplicate sample will be taken from this location
All reusable downhole sampling equipment will be thoroughly decontaminated by rinsing with
tap water and scrubbing with a brush approved soap solution, followed by rinsing with
distilled/de-ionized water.
GTA will ensure the correct bottleware is used and sufficient sample volumes are collected to
perform the requested analyses and QA/QC procedures for each media. Generally, surface soil
samples require two 4-ounce glass jars for metals analysis.
All soil samples will be collected using laboratory provided bottleware and will be placed
immediately in a chilled cooler with ice for transport to a North Carolina certified analytical
5

NCDEQ 25031-21-036 Wix Filtration II
March 22 2023 GTA Protect No. 31211876
laboratory under chain of custody procedures. Ate mperature blank will be placed in each sample
cooler submitted to the analytical laboratory. The 0.0-1.0ft samples will be analyzed for
hexavalent chromium and the 1.0-2.0ft samples will be put on hold at the laboratory. The 1.0-
2.0ft samples will be put on hold until the results of the 0.0-1.0ft samples are received. If there
are exceedances of regulatory limits in the 0.0-1.0ft samples, the 1.0-2.0ft samples will also be
run to determine if the contamination extends beyond surficial impacts. The 1.0-2.0ft samples
will be preserved at the lab until either analyzed or abandoned, and will not be held beyond the
maximum holding time for hexavalent chromium samples.
5.0 QA/QC PROCEDURES
For soil data quality assurance/quality control (QA/QC), GTA will collect one duplicate sample for
laboratory analysis. Laboratory analytical results that fall between the practical quantitation limit
of the laboratory equipment and the method reporting limit will be reported as a "J flag" result.
GTA will request Level II QA/QC including J flags on the chain of custody documentation. Sample
locations chosen for duplicate collection may be changed based on field observations and are
subject to change at the discretion of GTA.
QA/QC samples will be collected and analyzed in accordance with NCDEQ guidance which
suggests that one duplicate will be collected for every 20 samples per media per analytical
method. Thus, GTA will collect and submit one duplicate for laboratory analysis.
6.0 INVESTIGATION DERIVED WASTE
Upon completion, hand auger borings located on the former Wix Filtration property will be
backfilled with cuttings.
7.0 REPORTING
GTAwill prepare a Brownfield Assessment Report Addendum summarizing the sampling activities,
analysis results, conclusions, and recommendations. The report and attachments will include a
description of sampling activities, comparison of the data to regulatory screening levels or risk
thresholds, a figure depicting sampling locations, tabulated data, laboratory reports, a
photographic log, and signature by a North Carolina -licensed Professional Engineer or
Professional Geologist. Risk calculations will be based on maximum concentrations for all media
data.
