H&H Job No. WPP-014

1.0 Introduction

On behalf of White Point Partners, LLC (Prospective Developer or PD), Hart & Hickman, PC
(H&H) has prepared this Brownfields Assessment Work Plan (Work Plan) for the Yandle-
Witherspoon Supply Inc. Brownfields property (Brownfields Project No. [BPN] 24010-20-060)
located northwest of the N. Brevard Street and Belmont Avenue intersection in Charlotte,
Mecklenburg County, North Carolina (Site). The Site consists of five contiguous parcels
(Mecklenburg County Parcel Identification Nos. 08104102, 08104103, 08104105, 08104201,
and 08104203), the alleyway between parcels 08104203 and 08104102, and land located
between the Seaboard Coastline railroad and parcel 08104102. Collectively, the Site totals
approximately 6.0 acres of land located in a rapidly densifying residential and commercial use
area less than one mile east of uptown Charlotte along the LYNX Blue Line light rail corridor. A
Site location map is provided as Figure 1, and the Site is shown in Figure 2.

To address potential environmental concerns associated with historical on-Site and off-Site
operations, the Site parcels 08104102, 08104103, and 08104203 (previously a portion of
08104202) were entered into the North Carolina Department of Environmental Quality (DEQ)
Brownfields Program and received eligibility in a letter dated April 3, 2020. Since issuance of
the letter of eligibly, the PD plans to incorporate parcel 08104105, 08104201, the alleyway
between parcels 08104203 and 08104102, and land located between the Seaboard Coastline
railroad and parcel 08104102 into the Yandle-Witherspoon Supply Inc. Brownfields property.
The PD intends to submit an amended Brownfields Property Application to change the PD entity
to WP Yandle, LLC and add the additional land to the Brownfields property.

The western portion of the Site is developed with an approximate 65,480 square foot (sq ft)
2

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
warehouse building currently occupied by Yandle-Witherspoon Supply Inc. (Yandle-
Witherspoon). The southeastern portion of the Site is developed with an approximately 4,500
office building occupied by the Plaid Penguin. Proposed redevelopment of the Brownfields
property includes razing the existing Site buildings and construction of an apartment complex
and multi-story office building with associated parking areas and access roads.

1.1 Background Information

The Site was comprised primarily of residences, a church, and a portion of 14th Street from the
early 1910s until the early 1950s, when the southern portion of the Site was developed with a
small commercial building utilized for wholesale fruit distribution. By the late 1950s, a building
located in the eastern portion of the Site was occupied by a laundry and dry-cleaning facility, and
the commercial building located in the southern portion of the Site was utilized for paint storage.
The eastern Site building was occupied by a dry-cleaning facility until the late 1970s, a
construction company from the late 1970s until the early 2000s, and multiple retailers in the
2010s. The former dry-cleaner building in the eastern portion of the Site is currently occupied by
The Plaid Penguin, a food and beverage marketing business.

By the mid-1970s, the commercial building in the southern portion of the Site was expanded as
part of construction for the existing Site building. Additions to the existing Site building were
completed in the 1990s. The southern Site building has been occupied by Yandle-Witherspoon
since construction for warehousing and distribution of heating, ventilation, and air conditioning
(HVAC) systems and parts.

An east to west trending railroad spur was constructed across the Site in the late 1920s and was
utilized by the northern adjoining property until the 1980s. Northwestern and northern portions
of the Site were developed with the LYNX Blue Line Extension light rail tracks in 2015. A
portion of the unnamed tributary of Little Sugar Creek located in the northwestern portion of the
Site along the light rail corridor was piped below grade during construction of the light rail.

1.2 Previous Assessment Activities

To obtain additional information, H&H reviewed several reports prepared by others to document
previous environmental assessment completed at the Site. Pertinent historical analytical
documentation is provided as Appendix A, and a brief summary of information provided in the
environmental reports is provided below.

Former Gay Laundry and Cleaners
The eastern portion of the Site (1101 N. Brevard Street) was historically occupied by Gay
Laundry and Cleaners from at least 1959 until approximately 1979. During assessment activities
conducted at the Site in 2006, chlorinated volatile organic compounds (VOCs) including
tetrachloroethene (PCE) were detected in groundwater at concentrations above the DEQ 15A
NCAC 02L .0211 Groundwater Quality Standards (2L Standards). The facility was entered into
the North Carolina Department of Environmental Quality (DEQ) Dry-Cleaning Solvent Cleanup
Act (DSCA) Program (Project ID No. DC600044).

Assessment and risk evaluation activities were conducted at the former Gay Laundry and
Cleaners facility under the purview of the DSCA Program from September 2009 until 2010. In
August 2010, a Notice of Dry-Cleaning Solvent Remediation was recorded on the former Gay
Laundry and Cleaners tax parcel deed, and the DEQ issued a No Further Action (NFA) letter for
the chlorinated solvent release incident.

1990 UST Closure Activities
In March 1990, one 2,000-gallon gasoline underground storage tank (UST) was removed from
the Site. The UST was located southeast of the existing Site building near N. Brevard Street
(Figure 2). Upon removal of the UST, closure soil samples were collected from the base of the
excavation for analysis of benzene, toluene, ethylbenzene, total xylenes, total petroleum
hydrocarbons as diesel-range organics (TPH-DRO), and TPH as gasoline-range organics
(TPH-GRO). Closure soil sample analytical results indicate that no compounds were detected at
concentrations above the DEQ UST Section Action Levels or Maximum Soil Contaminant
Concentrations (MSCCs). Based on closure soil sample analytical results, DEQ issued a NFA
4

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
letter for the 2,000-gallon UST on October 15, 2007 (Leaking UST Incident No. 36379). UST
removal activities are documented in the Report of Site Assessment for Underground Storage
Tank Closure prepared by SPATCO Environmental and dated May 1990.

March 2002 Remedial Investigation Report
In 2000 and 2001, groundwater, surface water, and sediment assessment activities were
conducted at the Site by Brown and Caldwell to evaluate the potential for impacts from the
former Consolidated Engravers facility located adjacent to the southwest and topographically
upgradient of the Site. The Consolidated Engravers facility operated as a textile mill from the
late 1880s until at least the mid-1950s. The facility was entered into the DEQ Inactive Hazardous
Sites Branch (IHSB) following discovery of impacted groundwater attributed to historical mill
operations (IHSB ID No. NCD003162500).

Assessment activities completed at the Site under purview of IHSB included installation and
sample collection from four groundwater monitoring wells, collection of eight groundwater grab
samples, and collection of four co-located surface water and sediment samples from the unnamed
tributary of Little Sugar Creek located in the northern and eastern portions of the Site. Results of
the assessment activities are documented in a Remedial Investigation Report prepared by Brown
and Caldwell for the Consolidated Group, Inc. dated March 2002. Samples collected during 2000
and 2001 remedial investigation sampling activities are shown on Figure 2.

Groundwater analytical results indicated the presence of multiple VOCs at concentrations above
the 2L Standards in samples collected across the Site. During the October 2001 sampling event,
PCE (31 micrograms per liter [µg/L]) and trichloroethene (TCE, 24 µg/L) were detected in
sample SLGW-10, collected in the western and upgradient portion of the Site at concentrations
that exceed the 2L Standards of 0.7 µg/L and 3 µg/L, respectively. In addition, PCE (35 µg/L)
and TCE (37 µg/L) were also detected in downgradient groundwater sample SLGW-16,
collected in the northern portion of the Site at concentrations above the 2L Standards.

Surface water sample laboratory analytical results identified PCE (up to 110 D µg/L) and TCE
(up to 23 µg/L) at concentrations that exceed the DEQ 15A NCAC 02B .0211 Surface Water
5

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
Quality Standards (2B Standards) of 0.7 µg/L and 2.5 µg/L, respectively. The “D” laboratory
qualifier indicates that the sample was diluted by the laboratory for analysis.

Sediment analytical results identified low levels of PCE (up to 0.43 milligrams per kilogram
[mg/kg]) and TCE (up to 0.066 mg/kg) at concentrations above the laboratory method detection
limits, but below the DEQ ISHB Residential Preliminary Soil Remediation Goals (PSRGs). The
polycyclic aromatic hydrocarbon (PAH) benzo(a)pyrene (up to 0.42 JD mg/kg) was detected in
sediment at concentrations above the DEQ IHSB Residential PSRGs. The “J-flag” designation
for the benzo(a)pyrene detection indicates that the compound was detected at a concentration
above the laboratory method detection limit, but below the laboratory reporting limit resulting in
a laboratory estimated value. Metals, including arsenic (up to 2.7 mg/kg), lead (up to 435 mg/kg)
and hexavalent chromium (up to 7.1 mg/kg) were also detected at concentrations above the
Residential and/or Non-Residential PSRGs in sediment samples collected at the Site.

November 2016 Highland Park Mill Brownfields Assessment
In September 2016, Terracon Consultants Inc. (Terracon) performed Brownfields assessment
activities for the Highland Park Mill Brownfields property (BPN 20005-16-060) which now
includes northern portions of the Site (see Figure 2). Assessment activities conducted at the Site
included collection of four groundwater samples (GW-03, GW-06, GW-07, and GW-08) and two
surface water samples (SW-01 and SW-02). The assessment activities are documented in a
Brownfields Assessment Report prepared by Terracon dated November 17, 2016, and the
November 2016 Highland Mill Brownfields assessment sample locations collected at the Site are
shown in Figure 2.

Laboratory analytical results for groundwater samples collected in northern portions of the Site
indicated that no organic compounds were detected at concentrations above the 2L Standards.
However, several metals including arsenic (up to 14.7 µg/L), cadmium (up to 4.8 µg/L),
chromium (up to 282 µg/L), and lead (up to 74.6 µg/L) were detected in groundwater samples at
concentrations above the 2L Standards. Terracon attributed the elevated metals concentrations to
high turbidity in the groundwater samples. No other compounds were detected at concentrations
above the 2L Standards in the November 2016 groundwater samples collected in northern
portions of the Site.

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
Results of surface water samples collected from the unnamed tributary of Little Sugar Creek
located in the eastern portions of the Site indicated the presence of cis-1,2-dichloroethane (up to
1.3 µg/L) and barium (up to 110 µg/L) at concentrations below the 2B Standards. No compounds
were detected at concentrations above the 2B Standards in the November 2016 surface water
samples collected at the Site.

October 2018 Soil Stockpile Sampling
During 2018 redevelopment activities associated with the northern adjoining Highland Park Mill
Brownfields property and Norfolk Southern Intermodal Facility II Brownfields property (Norfolk
Southern, BPB 21036-17-60), excess soil generated during stormwater pipe and other utility
installation improvements was stockpiled in the northern portion of the Site, behind the former
Gay Laundry Site building. Excess soil was stockpiled in accordance with the Norfolk Southern
Environmental Management Plan (EMP), which allowed the transfer of soils between the
Highland Park Mill and Norfolk Southern Brownfields properties. In October 2018, composite
soil samples (CS-05 and CS-06) were collected to characterize the stockpile for disposal. The
October 2018 stockpile sample locations are shown in Figure 2. As shown in Figure 2, stockpile
soil sample CS-05 was collected to represent the northeastern half of the stockpile, and stockpile
soil sample CS-06 was collected to represent the southwestern half of the stockpile.

Laboratory analytical results for stockpile soil sample CS-05 indicated that no organic
compounds were detected at concentrations above the DEQ IHSB PSRGs. Several metals were
detected in the CS-05 sample at concentrations consistent with naturally occurring background
levels for the Site area.

Stockpile soil sample analytical results identified the benzo(a)pyrene (1.23 mg/kg),
benzo(a)anthracene (1.43 mg/kg), benzo(b)fluoranthene (1.45 mg/kg), and
dibenzo(a,h)anthracene (0.251 J mg/kg) at concentrations above the DEQ IHSB Residential
PSRGs in soil sample CS-06. Several metals were detected in the CS-06 sample at
concentrations consistent with naturally occurring background levels for the Site area.

Based on results of the stockpile soil sampling activities, DEQ provided approval to transport the
7

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
northeastern half of the soil stockpile represented by sample CS-05 to a Land Clearing and Inert
Debris (LCID) landfill for disposal in a letter dated October 31, 2018. Stockpile soil sampling
activities are documented in a 2018 Summary Redevelopment Report prepared by Terracon dated
January 30, 2018, and a copy of the DEQ approval for transport and disposal of the northeastern
half of the stockpile at a LCID landfill is provided in Appendix A.

December 2019 Phase I ESA
In December 2019, Terracon completed a Phase I Environmental Site Assessment (ESA) at the
Site. Results of the Phase I ESA identified the following recognized environmental conditions
(RECs) in connection with the Site:

 The property located adjacent to the southwest and topographically upgradient of the Site
is identified as the Alpha Mill Brownfields property (BPN 07009-03-060, see Figure 2),
and the northern adjoining property is identified as the Highland Park Mill Brownfields
property. The potential for impact to the Site from historical industrial use of the
adjoining properties was identified as a REC.

 Based on available environmental documents, the Alpha Mills Brownfields property
(formerly Consolidated Engravers) has documented chlorinated solvent groundwater
impacts. The potential for impact to the Site from documented chlorinated solvent
impacts on the upgradient Alpha Mill Brownfields property was identified as a REC.

The December 2019 Terracon Phase I ESA also identified the closed on-Site LUST incident to
be a historical REC (HREC).

As noted above, portions of the Site were entered into the DEQ Brownfields Program to address
potential environmental concerns associated with historical on-Site and off-Site operations
(eligibility letter issued April 3, 2020), and additional land will be added to the Brownfields
property upon submittal of an amended Brownfields Property Application. Upon eligibility in to
the Brownfields Program, the PD elected to participate in the Brownfields Program
Redevelopment Now option. As part of this process, a kick-off/data gap meeting with the PD and
8

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
DEQ Brownfields personnel was held on August 10, 2020 to discuss prior Site history, proposed
redevelopment plans, data gaps, and the proposed schedule for completing the Brownfields
Agreement. To address data gaps and DEQ Brownfields requests for additional assessment,
H&H has prepared this Work Plan to conduct Brownfields assessment activities at the Site.

The purpose of the Brownfields assessment activities described herein is to further evaluate the
potential for impacts at the Site for the protection of Site workers during redevelopment and for
future Site occupants. The Brownfields assessment activities discussed in the following sections
focus on collection of soil, groundwater, surface water, and soil gas samples. In addition to the
sampling activities, a receptor survey will be conducted to obtain information associated with
land use, potable water supply, and potential sensitive receptors in the area surrounding the Site.

A summary of the proposed Brownfields assessment activities is provided below.
9

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
2.0 Brownfields Assessment Activities

The Brownfields assessment activities will be conducted in general accordance with the DEQ
IHSB Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines) dated January
2020, the DEQ Division of Waste Management (DWM) Vapor Intrusion Guidance (VI
Guidance) dated March 2018, and most recent versions of the U.S. Environmental Protection
Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches
Quality System and Technical Procedures guidance.

Prior to conducting the proposed assessment field activities, H&H will contact North Carolina
811, the public utility locator, to mark subsurface utilities located on the Site. H&H will also
contract with a private utility locator to screen proposed sample locations for subgrade utilities
that may not be marked by the public locator. Additionally, soil boring locations will be hand
cleared to approximately 5 feet below ground surface (ft bgs) prior to use of mechanical drilling
equipment to further screen the boring locations for the presence of subsurface utilities.

In accordance with Mecklenburg County rules, H&H will also obtain a Subsurface Investigation
Permit (SIP) from Mecklenburg County prior to temporary monitoring well installation and
sampling. After completion of the activities, H&H will update the SIP on the Mecklenburg
County Well Information database with temporary monitoring well abandonment records
provided by a North Carolina licensed driller.

2.1 Receptor Survey

H&H will perform a Brownfields receptor survey in accordance with DEQ Brownfields Section
guidance. The receptor survey will include information about land use in the Site area including
zoning. H&H will also conduct a field search for water supply wells, basements, utility manways
and chases, storm sewers, other underground utilities, drains, and surface water within a 1,500 ft
radius of the Brownfields property boundary. In addition, H&H will review the online
Mecklenburg County Well Information System for potential wells in the area and, if warranted,
contact utility companies for information concerning underground utilities in the immediate area
10

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
of the Site. The receptor survey will be completed using the most current version of the
Brownfields Property Receptor Survey template form.

2.2 Soil Sampling Activities

H&H will conduct soil sampling as part of the Brownfields assessment activities. The purpose of
the soil sampling is to evaluate for potential impacts in areas of potential environmental concern
and to evaluate potential impacts in areas that may be disturbed during planned redevelopment
and grading activities.

Soil borings will be advanced in areas of the former on-Site UST, in a former paint storage area,
and in areas where significant cut is proposed during grading associated with redevelopment
activities. To evaluate soil conditions in these areas, H&H will collect seven (7) composite soil
samples from twenty-one (21) soil borings in areas of proposed cut, and two (2) grab samples
will be collected from the two soil borings advanced in the vicinity of the former on-Site UST
and former paint storage area.

Locations of the proposed soil borings to evaluate for potential impacts in areas of potential
environmental concern are shown on Figure 3, and proposed soil borings to characterize soil that
may be disturbed during future grading activities are shown in Figure 4. A tabular summary of
proposed samples depths, objectives, and laboratory analyses are summarized in Table 1.

A description of the soil sampling activities for each evaluation area is provided below.

Former Paint Storage Shed and On-Site UST
H&H will team with a qualified drilling contractor to advance two soil borings (SB-1 and SB-2)
at the Site. During boring advancement, soil will be logged for lithological description and field
screened for indication of potential impacts by observation for obvious staining, unusual odors,
and the presence of volatile organic vapors using a calibrated photoionization detector (PID).
Soil samples will be collected from the depth interval that exhibits the highest potential for
impact or as described below.
11

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
 One soil boring (SB-1) will be advanced to a depth of approximately 15 ft bgs in the
vicinity of the former UST basin located near the southeastern Site boundary. Based upon
field observations, one soil sample will be collected from the boring for laboratory
analysis from the depth interval with the highest potential for impacts based on field
screening results. If no obvious evidence of impact is observed during the field screening,
a soil sample will be collected at a depth interpreted to be below the base of the former
UST (i.e., 8 – 10 ft bgs).

 One soil boring (SB-2) will be advanced within the former paint area identified in the
south-central portion of the Site. The boring will be advanced to approximately 5 ft bgs
and a soil sample will be collected from the depth interval with the highest potential for
impacts based on field screening results. If no obvious evidence of impact is observed
during field screening, a sample will be collected from shallow soil (i.e., no greater than 2
ft bgs).

The soil samples selected for laboratory analysis will be 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 will be delivered to a North
Carolina certified laboratory under standard chain of custody protocols for laboratory analysis.
Soil samples will be analyzed for VOCs by EPA Method 8260, semi-VOCs (SVOCs) by EPA
Method 8270, Resource Conservation and Recovery Act (RCRA) metals by EPA Methods
6020/7471, and hexavalent chromium by EPA Method 7199. Metal concentrations will be
compared to background concentrations reported in the literature and established for nearby
Brownfields properties.

In-Situ Soil Characterization Sampling
H&H proposes to conduct soil assessment activities to identify areas at the Site that do not have
compound concentrations in soil above DEQ IHSB Protection of Groundwater and Residential
Use PSRGs to assist in export of non-impacted soil during grading activities.

Based on discussions with the PD, the project civil engineers, and review of the most recent
12

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
version of the cut-fill analysis for the Site, H&H understands that grading and construction
activities for the proposed redevelopment will generate up to approximately 6,500 cubic yards of
structurally unsuitable soil that cannot be re-used on-Site as fill and will likely need to be
transported off-Site. A copy of the most recent version of the cut-fill analysis prepared by
AGTEK and dated March 15, 2021 is provided as Appendix B.

There is limited space at the Site for stockpiling export soil during redevelopment activities.
Therefore, to expedite grading activities and to minimize the need to stockpile and manage large
volumes of soil during construction, H&H proposes to conduct soil assessment activities at the
Site to characterize soil in-situ before grading activities begin. The proposed in-situ soil
characterization assessment activities will include collection of soil samples from areas of
proposed cut.

Soil may need to be direct loaded onto trucks and transported off-Site during grading activities.
The data collected during the proposed assessment activities outlined in the following sections
will be used to predetermine whether export soil from the proposed excavations can be
transported to a LCID landfill, a construction and debris (C&D) landfill, a permitted landfill,
another Brownfields property for use as beneficial fill, and/or another suitable location with DEQ
approval.

H&H understands that the DEQ Brownfields Program and the DEQ Solid Waste Section will
review results of the soil assessment activities and assist the PD in determining a suitable facility
for the export soil. H&H also understands that the DEQ Solid Waste Section will issue a letter
recommending the type(s) of facilities that could manage the proposed export soil based on soil
characterization laboratory analytical results.

Proposed cut depths in central and north-central portions of the Site extends to approximately 5
ft bgs. Proposed cut depths in south-central portion of the Site extends up to approximately 4 ft
bgs. Based on proposed cut depths and the amount of export intended at the Site, H&H divided
the area of proposed cut into seven (7) in-situ soil characterization sections and proposes to
collect soil samples for laboratory analysis in each soil characterization section to represent
13

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
material that may need to be transport off-Site during grading activities. The in-situ soil
characterization sections (denoted by EX nomenclature) are depicted on Figure 4.

H&H will team with a qualified drilling contractor to advance multiple soil borings in each soil
characterization sections (Figure 4). The drilling contractor will advance each soil boring with a
decontaminated stainless steel hand auger. During boring advancement, continuous soil samples
will be collected from each boring from the center of the hand auger bucket. The soil samples
will be logged for lithologic description and inspected for the presence of visual and olfactory
indication of potential impacts and screened for the presence of volatile organic vapors with a
calibrated PID.

H&H understands that to obtain approval for export to a non-permitted receiving facility, DEQ
Brownfields and DEQ Solid Waste require an approximate sample frequency of a minimum of
one soil sample for every approximately 1,000 cubic yards of soil. Therefore, a total of seven (7)
in-situ soil samples will be collected as part of the assessment for characterization of the soil for
export.

Eighteen (18) soil borings will be advanced to approximately 5 ft bgs in the central and north-
central portions of the Site which are identified as in situ soil characterizations sections EX-1
through EX-6 (Figure 4). For each evaluation area, continuous soil sample aliquots will be
collected from each of the three aliquot soil borings and homogenized to form one composite soil
sample representative cut soil in areas EX-1 through EX-6.

Three (3) soil borings will be advanced to approximately 4 ft bgs in soil characterization section
EX-7 located in the south-central portion of the Site (Figure 4). Continuous soil sample aliquots
will be collected from each of the three soil borings advanced in EX-7. Soil sample aliquots from
each boring will be homogenized to form composite soil samples representative of cut soil in
EX-7.

The soil samples selected for laboratory analyses will be collected directly into dedicated
laboratory supplied sample containers, labeled with the date, time, and sample identification, and
14

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
placed in a laboratory supplied sample cooler with ice. The samples will be submitted to a North
Carolina certified laboratory under standard chain of custody protocols for analysis of SVOCs by
EPA Method 8270 and RCRA metals plus hexavalent chromium by EPA Methods
6020/7471/7199. One representative grab soil sample will be collected from each soil
characterization section, at each depth interval represented by a composite soil sample for a total
of seven grab samples. The grab soil samples will be collected from undisturbed portions of soil
directly into laboratory supplied glassware and submitted to a North Carolina certified laboratory
under standard chain of custody protocols for analysis of VOCs by EPA Method 8260.

Following sampling activities, the soil borings will be properly abandoned and the surfaces will
be repaired similar to pre-drilling conditions. Additionally, the soil sample locations will be
estimated using a hand-held global positioning system (GPS) unit or by measuring from known
benchmarks within the building (e.g., doors, windows, exterior walls, etc.).

2.3 Groundwater Sampling Activities

H&H will contract a qualified drilling contractor to advance borings for installation of two (2)
temporary groundwater monitoring wells at the Site. The purpose of the temporary groundwater
monitoring wells will be to evaluate current groundwater conditions in areas where the highest
concentrations of chlorinated solvents were previously identified. The locations of the proposed
temporary monitoring wells are shown on Figure 3 and are described below.

 One temporary monitoring well (TMW-1) will be installed in the western and upgradient
corner of the Site near previously collected groundwater sample SLGW-10; and
 One temporary monitoring well (TMW-2) will be installed in the northern portion of the
Site near previously collected groundwater sample SLGW-16.

The temporary groundwater monitoring well borings will be advanced with a track-mounted drill
rig capable of utilizing hollow-stem auger drilling techniques. During drilling, soil cuttings will
be collected and logged for lithologic description and field screened for the presence of obvious
staining, unusual odors, and elevated volatile organic vapors using a calibrated PID. Should
15

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
obvious evidence of impacts be observed based on field screening results, a soil sample will be
collected for laboratory analysis using the methodologies described in Section 2.2 above.

The temporary groundwater monitoring wells will be constructed of 1 or 2-inch diameter PVC
with a 10 to 15 ft section of pre-packed well screen set to bracket the water table and 1 or 2-inch
diameter PVC well casing to the ground surface. A sand filter pack will be placed from the
bottom of the borings to approximately 2 ft above the top of the well screens. The temporary
wells will be completed by placing a minimum of an approximately 2 ft thick hydrated bentonite
seal above the sand filter pack.

Once the temporary monitoring wells are installed, the wells will be allowed to equilibrate to
static conditions, and a decontaminated electronic water level indicator will be used to measure
the depth to the water table relative to the ground surface and tops of well casings in each well.
The wells will then be developed by removing a minimum of 3 to 5 volumes and until field
parameters have stabilized (pH± 0.1 Standard Units [SU] and conductivity varies no more than
5%).

After development, groundwater samples will be collected utilizing low flow/low stress purging
techniques using a peristaltic pump or bladder pump and dedicated polyethylene tubing. The
intake point of the pump tubing will be placed in the approximate mid-portion of the screened
interval of the well, and groundwater will be removed at a rate no greater than 200 milliliters per
minute. H&H will utilize a calibrated water quality meter to collect measurements of pH,
temperature, dissolved oxygen, oxidation reduction potential, turbidity, and specific conductivity
at three to five-minute intervals during the purging process. Purging will be considered complete
when the field parameters stabilize (pH ± 0.1 SU, conductivity varies no more than 5%, and
turbidity is less than 10 Nephelometric Turbidity Units [NTUs]).

Once groundwater parameters stabilize, groundwater samples for VOC analysis will be collected
directly into laboratory supplied sample containers using the “soda straw” method to eliminate
the potential for volatile compound loss through the pump head. Samples collected for the
remaining analyses will be collected directly into laboratory supplied sample containers from the
16

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
dedicated sample tubing discharge. The sample containers will be labeled with the sample
identification, date, time, and requested analysis, and placed in a laboratory supplied cooler with
ice. The groundwater samples will be delivered to a North Carolina certified laboratory under
standard chain of custody protocols for analyses of VOCs by EPA Method 8260, SVOCs by
EPA Method 8270, and RCRA metals by EPA Method 6020/7470.

The groundwater sample locations will be estimated using a hand-held GPS unit. Following
sampling activities, the temporary monitoring wells will be properly abandoned by a licensed
well driller and the surfaces will be repaired similar to pre-drilling conditions.

2.4 Surface Water Sampling Activities

H&H will collect two (2) surface water samples to evaluate current conditions of on-Site
portions of the unnamed tributary of Little Sugar Creek located in the eastern portions of the
Site. H&H will collect one upgradient surface water sample (BF-SW-1) in the northern portion
of the Site and one downgradient surface water sample (BF-SW-2) located near the eastern Site
boundary. The proposed surface water sample locations are shown in Figure 3.

Surface water samples will be collected directly into dedicated laboratory supplied sample
containers. The samples will be labeled with the sample identification, date, time, and requested
analysis and place in a laboratory supplied cooler with ice. The samples will be delivered to a
North Carolina certified laboratory under standard chain of custody protocols for analysis of
VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA metals by EPA Method
6020/7470, and total hardness by EPA Method 2340. The surface water samples will be analyzed
for total hardness to allow calculation of hardness dependent 2B Standards.

2.5 Soil Gas Sampling Activities

To evaluate the potential for structural vapor intrusion into the proposed apartment and office
buildings, H&H will install and sample six (6) temporary exterior soil gas monitoring points and
three (3) temporary sub-slab soil gas sampling points within existing Site building. The proposed
17

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
exterior and sub-slab soil gas sampling point locations are shown in Figure 3, and the sampling
activities are described below.

Exterior Soil Gas Sample Points
Four (4) temporary exterior soil gas monitoring points (SGP-1 and SGP-5 through SGP-7) will
be installed within the footprint of the proposed apartment or amenities buildings and two (2)
exterior temporary soil gas monitoring points (SGP-8 and SGP-9) will be installed within the
footprint of the proposed office building located in the northern portion of the Site (Figure 3).

The soil gas monitoring points will be installed at depths greater than 5 ft bgs and above the
estimated depth to the water table capillary fringe. Based on the anticipated depth to water at the
Site (10-15 ft bgs) it is anticipated that the soil gas points will be installed to a depth of
approximately 6 ft bgs. The soil gas point borings will be advanced utilizing a track-mounted
drill rig capable of using direct push technology (DPT) drilling techniques to advance an
approximate 6-inch stainless steel vapor screen attached to a length of Teflon® tubing. Following
advancement, the DPT tooling will be retracted and the annular space around the vapor screen
will be filled with filter sand to a depth of approximately 6-inches above the vapor screen.
Following installation of the sand, hydrated bentonite will be installed in the boring from the top
of the sand to near the ground surface.

Sub-Slab Soil Gas Sample Points
H&H proposes to install three (3) sub-slab soil gas sample points (SGP-2, SGP-3, and SGP-4)
for collection of soil gas samples beneath the existing Site building. The samples are proposed in
locations that will be within the footprint of residential or amenity units of the proposed
apartment buildings. The proposed sub-slab soil gas sample locations are shown on Figure 3.

The sampling points will be 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 will then be placed in the pilot hole, and a 5/8-inch diameter drill bit will
be utilized to advance the boring through the concrete slab. Following concrete borehole
advancement, loose concrete cuttings will be removed from each boring, and a Cox-Colvin
18

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
Vapor Pin™ (vapor pin) assembly (brass sampling point and silicone sleeve) will be seated in the
borehole using an installation/extraction tool and hammer.

Soil Gas Sampling
The sub-slab and exterior soil gas samples will be collected utilizing laboratory supplied
Summa® canisters (1 or 3-liter canisters depending on laboratory availability) 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, a “shut-in” test will be
conducted on the sampling train and helium leak checks will be conducted at each soil gas
sampling point. The purpose of the shut-in test and helium leak check is to ensure short
circuiting with ambient air does not occur during sampling. A description of the shut-in test and
helium leak testing procedures is provided below.

The shut-in test will be 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 is “closed”, the sample valve on the Summa® canister will be opened and the
reading on the vacuum gauge will be recorded. The Summa® canister sample valve will then be
closed and the vacuum gauge will be observed to ensure no vacuum loss occurs. If the vacuum
reading remains the same, the shut-in test will be considered successful. If vacuum loss occurs,
the flow regulator and/or brass cap will be reseated and the shut-in test will be repeated until the
vacuum reading remains stable.

Following the shut-in test, the Summa® canister will be 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 will be performed. The leak check will be performed by constructing a shroud over
the sampling train and flooding the shroud with helium gas. A calibrated helium gas detector will
be utilized to measure helium concentrations within the shroud. Once helium concentrations
stabilize within the shroud, the sample tubing will be 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
will then be analyzed using the helium gas detector to ensure that helium concentrations in the
soil gas point are less than 10% of the helium concentrations measured within the shroud.
19

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
Following successful leak checks, the soil gas samples will be collected. Vacuum readings on the
Summa® canister will be 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 will be
maintained within the canisters at the conclusion of the sampling event in accordance with DEQ
DWM guidance. Following sample collection, the Summa® canisters will be shipped to a
certified laboratory under standard chain-of-custody protocols for analysis of VOCs by EPA
Method TO-15. The laboratory will be requested to use reporting limits that are below DEQ
DWM Residential Vapor Intrusion Soil Gas Screening Levels (SGSLs).

After sampling is complete, the sample locations will be estimated using a hand-held GPS unit or
by measuring from known benchmarks within the buildings (e.g., doors, windows, exterior walls,
etc.), and the sample locations will be abandoned with surfaces repaired similar to pre-drilling
conditions.

2.6 Quality Assurance – Quality Control

Non-dedicated equipment and tools will be decontaminated prior to use at each boring or
sampling location or following exposure to soil or groundwater. The following samples will be
collected for quality assurance/quality control (QA/QC) purposes:

 One duplicate soil, groundwater, and surface water sample will be collected and analyzed
for the same parameters as the parent samples.
 One trip blank will accompany the groundwater samples during the field activities as well
as during sample shipment and will be analyzed for VOCs by EPA Method 8260.
 One duplicate soil gas sample will be collected using a laboratory supplied “t-fitting”
which allows for two soil gas samples to be collected from one soil gas monitoring point
simultaneously. The duplicate soil gas sample will be submitted for analysis of VOCs by
EPA Method TO-15.

Laboratory QA/QC procedures will be employed to ensure appropriate sample handling and
analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be
20

u:\aaa-master projects\white point partners (wpp)\wpp-014 yandle witherspoon\brownfields assessment\work
plan\brownfields assessment work plan_yandle witherspoon supply.doc
conducted in accordance with the method protocols and will include regular equipment
maintenance, equipment calibrations, and adherence to specific sample custody and data
management procedures. Samples will be analyzed in conjunction with appropriate blanks,
laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking
standards in accordance with approved methodologies to monitor both instrument and analyst
performance. Laboratory reporting limits for each analyte will be at or below appropriate
screening criteria, where possible. Additionally, H&H will request that the laboratory include
estimated concentrations for compounds that are detected at levels above the laboratory method
detection limit, but below the laboratory reporting limit (J flags).

The laboratory analytical data report and QA package for each group of samples submitted to
and analyzed by the subcontracted laboratory will be provided in an appendix to the final report.
Laboratory QA data consistent with Level II documentation will be provided for this project.
A copy of the completed chain of custody record and shipping receipt will be appended to the
corresponding laboratory analytical report included with the final report.

2.7 Investigation Derived Waste

Investigation derived waste (IDW) generated during the proposed assessment activities will be
managed in general accordance with DEQ IHSB Guidelines. IDW generated during the
assessment activities will be thin spread on-Site. However, if significant impacts are suspected
(i.e., free-product) the soil cuttings will be containerized in labeled 55-gallon drums and staged
on-Site pending analytical results of a composite IDW sample. Based on laboratory analytical
results of IDW samples, the drums will be transported off-Site to a suitable facility for disposal.
21

plan\brownfields assessment work plan_yandle witherspoon supply.doc
3.0 Reporting

Following completion of the assessment activities and receipt of the analytical data, H&H will
document our findings in a Brownfields Assessment Report. The report will include a description
of the sampling activities; a figure depicting sample locations; boring logs for the soil borings,
temporary well borings, and soil gas monitoring points; temporary well and soil gas monitoring
point construction logs; groundwater sampling logs; laboratory analytical data; a discussion of
the data in comparison to regulatory screening levels; and conclusions and recommendations
concerning our activities. H&H will also use the most recent version of the DEQ risk calculator
to further evaluate potential risks based on the data, if warranted.

Subject: Brownfields Soil Management Options
Highland Park Mill Brownfield Property
Charlotte, Mecklenburg County
Brownfields Project No. 20005-16-060

Dear Mr. Levell:

The North Carolina Department of Environmental Quality (DEQ) Brownfields Program received
a request to export fill from the Highland Park Mill Brownfields Property (20005-16-060), owned
by White Point Paces Partners, LLC. This request was submitted on your behalf by Mr. Chris
Corbitt, PG of Terracon Consultants, Inc. on October 16, 2018 via the Composite Soil Sample
Analytical Results Summary and Soil Export Request letter. Transfer to another Brownfields
property was subsequently approved; however, per recent phone conversations with Mr. Corbitt
the transfer of soils associated with CS-05 samples to another brownfields property was no longer
an option. DEQ Brownfields and Solid Waste Section reviewed the provided stockpile sampling
results as well as previously collected soil samples for arsenic from the Reeves Land Clearing and
Inert Debris Landfill. Based upon our review, the stockpiled soils may be managed as follows:

• Soils associated with samples CS-05/CS-05A may be managed at the Reeves LCID
Landfill, or another LCID Landfill with background arsenic concentrations similar to those
identified at the Brownfields Property, a Construction & Demolition (C&D) Landfill,
Municipal Solid Waste (MSW) Landfill, or at another Brownfields Property with prior
DEQ Brownfields approval.
• Soils associated with the samples CS-06/CS-06A may be managed at a MSW Landfill, or
at another Brownfields Property with prior DEQ Brownfields approval.

Per the Highland Park Mill EMP, the soils will be field screened during excavation prior to export
from the property. If unanticipated impacts are identified during excavation, please refer to the
EMP for further actions and cease transfer until appropriate characterization can be completed.

Mr. Jay Levell
October 31, 2018

In accordance with the site’s approved EMP, an annual Redevelopment Summary Report will be
submitted to DEQ Brownfields. Details related to the disposition of this soil including but not
limited to, total volume, general description of field screening efforts, etc. should be included with
the Redevelopment Summary Report.

Please be advised that this approval does not waive any applicable requirement to obtain any
necessary permits, licenses or certifications which may be required from other state or local
entities. If you have questions about this correspondence or require additional information, please
feel free to contact Joselyn Harriger by phone at 704-235-2195 or by email at
