Dear Ms. Eckard:
Geosyntec Consultants of NC, P.C. (Geosyntec), on behalf of our client, Wesley Village, LLC
("Client"), has prepared this Work Plan for Brownfields Agreement (Work Plan) for the Wesley
Village II Brownfields Property located at 2000 Wesley Village Road and 2000 Rushing Creek
Lane in Charlotte, North Carolina ("Site"). A Brownfields Agreement (BFA) for the Site was
finalized and recorded on 28 August 2012 between Wesley Village, LLC (the Prospective
Developer [PD]) and The North Carolina Department of Environment and Natural Resources
(NCDENR, now North Carolina Department of Environmental Quality [NCDEQ]). At the time,
anticipated redevelopment was for commercial and industrial use, and the land use restrictions
(LURs) included in the BFA reflected commercial and industrial usage. Residential
development in the form of townhomes is now being considered for the property and we are
requesting an Amendment to the Recorded BFA.
On 9 March 2021, a virtual meeting was conducted with Geosyntec, the PD, and NCDEQ (Ms.
Sharon Eckard and Mr. Bruce Nicholson) to discuss a proposed path forward to modify the
BFA for residential use. Based on this conversation, the next step in the Brownfields process is
preparation and submittal of a Work Plan including soil, groundwater, soil gas, and surface
water/sediment sampling for NCDEQ approval. This Work Plan is intended to collect additional
data to establish baseline conditions and address environmental data gaps identified during the
call. A draft figure showing proposed sampling locations was sent to NCDEQ on 18 March
2021 and approved on 30 March 2021. We look forward to your review and approval of this
Work Plan.
Sincerely,
Amy Kenwell, PG (Nc, sc) Kaitlyn Rhonehouse, PE (NC, VA, FL)

1. INTRODUCTION
Geosyntec Consultants of NC, P.C. (Geosyntec), on behalf of Wesley Village, LLC ("Client"), has
prepared this Work Plan for Brownfields Agreement (Work Plan) for the Wesley Village II
Brownfields Property located at 2000 Wesley Village Road and 2000 Rushing Creek Lane in
Charlotte, North Carolina ("Site"; Figure 1). The Site consists of Mecklenburg County Parcels
07104111 and 07104113. A Brownfields Agreement (BFA) for the Site was finalized and recorded
on 28 August 2012 between Wesley Village, LLC and The North Carolina Department of
Environment and Natural Resources (NCDENR, now North Carolina Department of Environmental
Quality [NCDEQ]). At the time, anticipated redevelopment was for commercial and industrial use,
and the land use restrictions (LURs) included in the BFA reflected commercial and industrial usage.
Residential development in the form of townhomes is now being considered for the property and
we are requesting an Amendment to the Recorded BFA.
A proposed redevelopment plan is depicted on Figure 2, which includes the construction of 6 multi-
family residential buildings (townhomes) and surrounding paved parking areas and access roads.
This Work Plan presents a summary of the previous environmental assessment and remedial
activities and proposed additional assessment activities at the Site to collect additional data to help
evaluate residential use at the Site. The completion of the work presented herein is intended to
support issuance of a new BFA and facilitate Site redevelopment.
1.1 Background
The Site is located in Mecklenburg County, Charlotte, North Carolina (Figure 1) and consists of
two parcels (identified as Mecklenburg County parcel IDs 07104111 and 07104113) that are
separated by Wesley Village Road and total to approximately 2.1 acres. The eastern parcel (2000
Wesley Village Road) is currently undeveloped woodland and bordered to the east by Stewart
Creek. The western parcel (2000 Rushing Creek Lane) is vacant cleared land and primarily consists
of a grassy field and dry stormwater retention pond with an older terminated portion of Thrift Road
running through the southwestern portion of the parcel. The western parcel was formerly part of
the adjacent northern parcel listed as 2000 Thrift Road in previous reports.
The Site was agriculturally developed as far back as 1938. The northeastern -most portion of the
western parcel was reported to have first been developed for commercial use in 1957 as an
approximately 62,000 square foot meat and poultry processing facility belonging to the Wampler
Longacre Meat Processing Plant (the Wampler Plant). This facility operated as a meat and poultry
processing facility until 1995 under various names. Several former underground storage tanks
(USTs) have been reported at the Wampler Plant including a 10,000-gallon heating oil tank and 6
other former USTs that have been removed.

1.2 Environmental Site and Vicinity History
This section provides a comprehensive summary of previous assessment activities conducted at
the former Wampler Plant (which includes the Site) and includes testing of various media
including soil and groundwater. The documents referenced in this Section have been previously
provided to NCDEQ for their records and are, therefore, not attached.
The western parcel was formerly a part of the northern adjacent parcel (2000 Thrift Road parcel).
This 2000 Thrift Road parcel was operated by the former Wampler Plant from approximately 1958
through 1995. The Wampler Plant operated a 10,000-gallon UST on the 2000 Thrift Road Parcel,
which was used to store No. 2 oil for a boiler from the mid- 1970s to 1995. The 2000 Thrift Road
parcel also reportedly contained 6 other USTs that were removed in 1990. The 10,000-gallon UST
and boiler were located north of the present-day western parcel of the Site (off -site). The USTs
removed in 1990 were partially located on the western side of the present-day eastern parcel of the
Site. The table below documents UST information.

Phase I and II Environmental Site Assessments (ESAs) were performed for the 2000 Thrift Road
parcel in 1996 and 1997, respectively, by EnecoTech, Inc. (EnecoTech). EnecoTech reported oil
and grease concentrations as high as 0.290 parts per million (ppm) in the former UST area adjacent
to the eastern corner of the former building. Soil samples were also collected near the 10,000-
gallon UST, near surface staining, near a hydraulic lift, near a former grease trap, adjacent to
upgradient facilities, and generally across the Site (for pesticides and herbicides) and did not find
indication of environmental concern in these areas. Of sampled areas, only the former UST area
samples were on the present-day eastern Site parcel and no samples were collected on the western
Site parcel.

The 10,000-gallon UST (located off -site) and related piping were removed on 10 February 1998.
On 2 March 1998, a notification of a release was reported to NCDEQ and the release was
designated as Incident No. 18881. Subsequent soil sampling conducted by Enviroprobe, Inc.
(Enviroprobe) revealed total petroleum hydrocarbons diesel range organics (TPH-DRO)
detections as high as 23,000 ppm in the 10,000-gallon UST pit area, primarily below the piping
system. Approximately 420 tons of contaminated soil were removed in two stages and stockpiled
on -site. In a 20 May 1998 Limited Site Assessment and Soil Clean-up Report, Enviroprobe
reported that confirmation soil sampling in the sidewalls and base of the excavated area revealed
that detections did not exceed Maximum Soil Contaminant Concentrations (MSCCs). Enviroprobe
also installed a monitoring well in the former UST area to assess groundwater quality.
Groundwater sample results were reported below the method detection limit. On 4 August 1998,
a No Further Action (NFA) was issued for the former Wampler Plant.
In November and December 2006, LVI Services, Inc. (LVI) conducted demolition of the former
facility including demolition of the 62,000 square -foot Wampler Plant building and removal of
3,700 gallons of oil, sludge, and wastewater from the grease trap located on the former 2000 Thrift
Street parcel (off -site). During demolition, LVI encountered the former off -site UST pit that had
previously contained the 10,000-gallon UST. LVI excavated test pits to verify no soil remained
above NCDEQ gross contamination levels in the former tank area. TPH-DRO was only identified
in 2 of the 4 samples at concentrations of 45 and 8.4 ppm. The 45 ppm concentration exceeded the
State Action Level (at the time) of 10 ppm; however, due to the closure of this incident in 1998,
MACTEC Engineering and Consulting (MACTEC) reported that no further investigation was
warranted. MACTEC also observed and removed 5 tons of stained soil from a former oil drum
area which was located on -site within the present day western parcel. Confirmation soil sampling
was conducted in the oil drum area, near the hydraulic lift, the grease trap, and areas of staining
(all off -site with the exception of the oil drum area) and revealed no detectable concentrations.
During the January 2007 ESA performed by MACTEC, groundwater monitoring wells were
installed in the storm drain area (off -site) and oil drum area (on -site). Detectable concentrations of
volatile organic compounds (VOCs) were present; however, only tetrachloroethylene (PCE),
which was detected at 4.5 micrograms per liter (µg/L) in the drum storage area, was above the
respective North Carolina Administrative Code (NCAC) 2L Groundwater Standard (2L Standard)
of 0.7 µg/L.
Following soil sampling in November 2006, MACTEC conducted an excavation of the former
UST area located partially on -site in the present day eastern parcel (6 USTs near the northeast
corner of the former building) and submitted an Initial Abatement Measures Report (IAMR). The
excavation reached 14-15 feet below ground surface (ft bgs) and 1,212 tons of soil were removed.
Sidewall and bottom confirmation soil samples were collected and none of the soil samples
exceeded the Residential MSCCs. Hydrocarbon concentrations in some samples exceeded the soil-
CAR210058 3 04/2021

Geosyntec°

Geosyntec Consultants of NC, P.C.
to -water MSCCs. Four groundwater monitoring wells were installed in this area in August 2007
by MACTEC. Only two compounds were detected above the 2L Standard and include benzene
(47.2 µg/L) and naphthalene (25.6 µg/L). MACTEC demonstrated through modeling that
groundwater would not impact Stewart Creek and an NFA was issued on 17 September 2007.
A 2 January 2008 Phase II ESA performed by Professional Service Industries, Inc. (PSI) reported
Site groundwater samples contained PCE and vinyl chloride above their respective 2L Standards.
The groundwater impacts were detected in wells located in the Site's eastern parcel and in the road
just east of the western parcel.
In 2011, Hart & Hickman (H&H) conducted a soils assessment on a portion of the Site. H&H
reported benzo(a)pyrene and benzo(b)fluoranthene (polynuclear aromatic hydrocarbons [PAHs])
and arsenic exceeded Residential or Non -Residential soil screening levels from composited
samples.
In addition to potential impacts from the former Wampler Plant, an off -site fueling station (7-
Eleven) is located adjacent to the Site on the west, just across Thrift Road. Prior to construction of
the 7-Eleven in 2014, that property was occupied by a Shell fueling station from an unknown date
until at least 1998 (based on historical aerial imagery). The current and former fueling stations are
projected to be upgradient of the Site and may be a source of off -site impacts to the property.
A BFA for the Site was finalized and recorded on 28 August 2012 between Wesley Village, LLC
and NCDEQ. The Site constituents of concern (COCs) listed on the BFA include: PCE and vinyl
chloride for groundwater and benzo(a)pyrene, benzo(b)fluoranthene, and arsenic for soil though
arsenic was consistent with North Carolina background concentrations.
2. SCOPE OF WORK
Based on a review of readily available historical Site -related documents and discussions with the
NCDEQ Brownfield's Project Manager, Geosyntec proposes to perform supplemental assessments
to address data gaps in support of obtaining a BFA which approved residential use.
The proposed scope of work has been developed in consideration of potential reuse of the Site and
seeks to:
1. Characterize potential groundwater impacts;
2. Characterize soil throughout the Site;
3. Update assessment of former oil drum area and former UST;
4. Evaluate vapor intrusion (VI) potential within proposed future building footprints; and
CAR210058 4 04/2021

Geosyntec Consultants of NC, P.C.
5. Characterize potential risks from Stewart Creek.
A description of the field methodologies and proposed sampling techniques is presented in the
following section, as well as associated quality assurance and quality control (QA/QC) measures,
investigation -derived waste (IDW) management, and associated reporting. Proposed locations are
depicted on Figure 2 and sample depths and laboratory analyses are summarized in Table 1.
3. SAMPLING METHODOLOGY
3.1 Health and Safety Planning and Utility Clearing
Prior to the start of work, Geosyntec will prepare a site -specific Health and Safety Task Hazard
Analysis in general accordance with the Occupation Safety and Health Administration (OSHA)
rules (29 CFR 1910.120). To address potential underground utilities, Geosyntec will contact the
North Carolina 811 one -call system a minimum of 72 business hours before beginning the
assessment to notify member utilities of the subsurface work. A private utility locator may also be
subcontracted to perform a geophysical survey to locate and mark subsurface utilities at the
proposed boring locations. Final sampling locations will be modified, if necessary, based on utility
locations. Procedures will generally follow the Operating Procedures as determined by the U.S.
Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division
(SESD). The most current versions of these operating procedures can be downloaded
at:https://www. epa. gov/qualiiy/quality-system-and-technical-procedures-sesd-field-branches.
Additional media specific procedures are discussed further below.
3.2 Soil Sampling
Ten (10) borings (DPT-1 through DPT-10) are proposed for the collection of soil samples.
Proposed soil boring locations are shown on Figure 2.
Soil borings will be hand -augured to a depth of 2 ft bgs or refusal. Geosyntec will screen each
boring with a photoionization detector (PID) and document the general soil lithology of each
boring. Soil staining and/or odors will be recorded in the field. Saturated soil samples, if
encountered, will not be collected for analytical testing.
Soil samples will be composited from ground surface to 2 ft bgs, with the exception of samples
analyzed for VOCs. A grab sample will be collected for VOC analysis at the depth from each
boring corresponding to the highest PID reading or if olfactory or visual evidence of contamination
is identified, but no shallower than 0.5 ft bgs. Soil samples will be collected in accordance with
EPA Guidance (LSASD, June 2020a).
CAR210058 5 04/2021

Geosyntec°
consultants
Geosyntec Consultants of NC, P.C.
Soil samples will be sent off -site to a North Carolina -certified laboratory on ice and under chain
of custody procedures. Based upon the known Site environmental history, and as requested by
NCDEQ, the soil samples will be analyzed for VOCs by EPA Method 8260, semi -volatile organic
compounds (SVOCs) by EPA Method 8270, and the eight (8) Resource Conservation and
Recovery Act (RCRA) metals by EPA Method 6020, including mercury by EPA Method 7471 and
speciation for hexavalent chromium by EPA Method 7199 (Table 1). One QC duplicate soil
sample will be collected. Sampling equipment will be decontaminated prior to each sample using
distilled water and Liquinox (LSASD, June 2020b). Locations of each soil sample will be
measured in the field using a global positioning system (GPS) with sub -meter accuracy. Following
sampling, each boring will be abandoned using bentonite or grout or converted to a monitoring
well, as described in Section 3.3
3.3 Monitoring Well Installation and Groundwater Sampling
Geosyntec will contract with a North Carolina licensed driller to install six (6) temporary
monitoring wells. Proposed temporary well locations are shown on Figure 2. Monitoring well
boreholes will be advanced using Geoprobe' or hollow and solid stem auger methods. Boreholes
will be advanced to a maximum of 10 feet below first encountered groundwater (estimated to be
encountered between 10 and 15 ft bgs).
Type II temporary monitoring wells (TMW-1 through TMW-6) will be installed in associated
boreholes in general accordance with NCAC Title 15A Subchapter 02C (NCAC 2C). Boreholes
will be converted into Type II monitoring wells set to estimated depths of 15 to 25 ft bgs. Each
monitoring well will be constructed of 1-inch Schedule 40 polyvinyl chloride (PVC), 10-foot
standard 0.010-inch slotted screen, and 1-inch Schedule 40 PVC riser pipe to surface. The screened
interval depth will be field determined based on the lithology and will be designed to bracket the
observed water table. Remaining annular space around the monitoring well will be backfilled with
filter pack sand to a minimum of approximately one foot above the top of the well screen followed
by a 1-foot thick hydrated bentonite seal place in two 6-inch lifts. Following installation, each
monitoring well will be developed by purging until visibly clear using a peristaltic pump or
submersible pump and dedicated tubing. Temporary wells will be secured using locking j-plug
caps.
Groundwater level measurements relative to the top of the inner PVC well casing (top of casing
[TOC]) will be obtained from each monitoring well at least 24-hours following well development
and prior to sampling. After groundwater level measurements are obtained, a peristaltic pump and
dedicated polyethylene tubing will be used to purge wells in general accordance with low -flow
purging methods referenced in EPA Region 4, SESD, Groundwater SOP (effective date 27 April
2017). Stabilization will occur when, for at least three consecutive measurements:
CAR210058 6 04/2021

Geosyntec°
consultants
Ceosyntec Consultants of NC, P.C.
• the pH remains constant within 0.1 Standard Unit (SU);
• specific conductance varies no more than 5 percent; and
• turbidity has either stabilized or is below 10 Nephelometric Turbidity Units (NTUs) (twice
the Secondary Drinking Water Standard of 5 NTUs).
Field forms with recorded parameters including but not limited to pH, dissolved oxygen (DO),
specific conductance, turbidity, oxidation-reduction potential (ORP), and purge information (start
time, measurements, volumes etc.) will be included in the final report.
A groundwater sample will be collected from each monitoring well following stabilization.
Groundwater samples will be collected and analyzed for VOCs by EPA Method 8260, SVOCs by
EPA Method 8270, lead and total chromium by EPA Method 6020, and speciation for hexavalent
chromium by EPA Method 7199 (to be placed on hold pending total chromium results) (Table 1).
Samples will be placed on ice in dedicated coolers and submitted to a North Carolina -certified
laboratory for analysis following chain of custody procedures (Section 5.2). One QC duplicate
groundwater sample will be collected.
Following sampling, temporary wells will be abandoned by removing the PVC and filling the hole
with hydrated bentonite or grout.
3.4 Vapor Intrusion Assessment Methodology
Geosyntec proposes to install soil gas probes (SGPs) at 13 locations within the footprint of the 6
proposed buildings on -site to evaluate the VI potential in the residential buildings. It is anticipated
that one SGP implant will be installed at each location to a depth of approximately 5 to 10 ft bgs.
SGPs will not be installed less than 2 feet from the observed water table (expected to be
encountered between 10 and 15 ft bgs) or less than 5 feet from ground surface. Based on existing
Site conditions, some proposed soil gas samples may be in paved areas, however, they are not true
"sub -slab" soil gas samples, as the paving does not likely have a permeable gravel layer that would
commonly be included beneath a building. The soil gas sample depth has been chosen to reflect
these conditions. Soil gas samples will be analyzed for VOCs using EPA Method TO-15, as
outlined in Table 1.One QC duplicate soil gas sample will be collected.
Installation of Soil Gas Probes
SGP boreholes will be drilled by a North Carolina -licensed driller and will be advanced using
GeoprobeTM soil coring technology. Soil from each core will be visually inspected, screened with
a PID, and classified for lithology. Installation of SGPs will be conducted in accordance with the
EPA Region IV standard operating procedures (LSASD, February 2020).
CAR210058 7 04/2021

Geosyntec°
consultants
Geasyntec Consultants of NC, P.C.
The following SGP design is prescribed in an effort to minimize the potential for sample dilution
due to leakage from the surface. The SGPs will consist of/4-inch diameter Nylaflow tubing, fitted
with a GeoprobeTM stainless steel soil gas sampling implant (6-inch screen interval). A sand filter -
pack will be placed around the soil gas probe screens, to a height of 6 inches above the screen.
Granular bentonite and water will be placed in two 3-inch lifts above the filter -packs to form a
bridge, and a slurry consisting of powdered bentonite and water will be placed above the bridge to
ground surface. The backfill slurry will be placed as the GeoprobeTM casing is withdrawn to help
prevent collapse of geologic materials and potential compromise of the seals. A compression
fitting and valve will be fitted to the top of the probe. The locations of each SGP will be measured
in the field using a GPS with sub -meter accuracy. SGPs will be allowed to equilibrate for 24 to 48
hours prior to sampling. General SGP construction details are presented on Figure 3.
Soil Gas Sampling
A soil gas sampling assembly will be setup as shown in general accordance with Figure 4 and will
be performed in accordance with the NCDEQ Division of Waste Management's (DWM's) March
2018 Vapor Intrusion Guidance (NCDEQ, 2018) and the EPA standard operating procedures
(LSASD, February 2020). A peristaltic pump may be substituted for the "lung box."
Prior to sampling, pressure will be measured at each SGP location using a manometer and methane
will be measured using a landfill gas meter (GEM5000 or equivalent). A second round of pressure
and methane measurements will be collected at least 24 hours following the initial readings. A
"shut-in test" will be conducted to assess the assembly for air leaks. Upon successful completion
of the shut-in test, the assembly will be purged to remove atmospheric air entrained during
installation. Field screening using a PID for organic vapors and landfill gas meter (GEM5000 or
equivalent) for methane, carbon dioxide, and oxygen will be conducted during purging activities
prior to sample collection. During field screening a tracer test will be conducted to verify that a
significant amount of atmospheric air does not enter the sample through the annular seal or
associated fittings. A shroud will be placed around the ground surface of each probe and soil gas
sampling assembly prior to sample collection and a tracer gas (e.g., helium) will be added inside
the shroud during the purging process. The concentration of tracer in the shroud and in the field
screening samples will be recorded with a field meter. If field screening indicates the tracer exceeds
5% of the concentration in the shroud, fittings will be checked and/or the probe will be
resealed/replaced as needed to obtain a sample with appropriate integrity. Three casing volumes
will be purged and samples will be collected as soon as practicable after purging.
Soil vapor samples will be collected using 1-liter batch -certified Summa canisters supplied by the
laboratory. The initial vacuum in the Summa canister will be measured before use to confirm leaks
have not occurred during shipping. After sample collection, the residual vacuum will also be
CAR210058 8 04/2021

Gea ,,n Consultants of NC, P.C.
measured and recorded and should be no less than -5 inches of mercury (inHg). Samples will be
collected by connecting the Summa canister directly to the probe through a 200 milliliter per
minute flow controller connected using Swagelok fittings and Nylaflow tubing.
Following sample collection, soil gas probes will be left in place until data has been reviewed by
NCBP and confirmation has been received that probes do not need to be re -sampled.
3.5 Surface Water and Sediment Sampling
Surface water and sediment will be sampled from the two co -located positions, one upstream and
one downstream, shown in Figure 2. Sediment and surface water samples will be co -located and
collected as grab samples from the Stewart Creek at each location without entering the
water. Samples will be collected from the river bank via a scoop (stainless steel or glass) or the
sample container directly attached to a piece of conduit as described in EPA SESD Procedures for
Sediment Sampling SESDPROC-200-R3 (EPA, 2014) and Surface Water Sampling SESDPROC-
201-R4 (EPA, 2016). At each location, the surface water sample must be collected first, before
collecting the sediment sample, with the sample container facing upstream to minimize sample
contamination due to agitation of bottom sediments. If water level is very shallow or turbulent,
samples may be collected in a separate, pre -cleaned collection container and immediately decanted
into the sample container to reduce turbidity. Care must be taken to minimize loss of fine sediment
particles while scooping the sediment sample. Alternate sampling equipment and methodology
may be used based on field considerations. Samples will be properly preserved, labeled, logged
onto a chain -of -custody form, placed into an iced cooler, and sent to the laboratory for analysis.
Surface water samples will be analyzed for VOCs by EPA Method 8260 and SVOCs by EPA
Method 8270 while sediment samples will be analyzed for VOCs by EPA Method 8260, SVOCs
by EPA Method 8270, and the eight (8) RCRA metals by EPA Method 6020, including mercury
by EPA Method 7471 and speciation for hexavalent chromium by EPA Method 7199. One QC
duplicate surface water and sediment sample will be collected.
4. LABORATORY ANALYSIS
4.1 Laboratory Analysis
Following Site collection, soil, groundwater, surface water, and sediment samples will be sealed
and submitted to a North Carolina -certified laboratory and soil gas samples will be submitted to a
NAICs-certified laboratory following chain of custody procedures (Section 5.2). Samples will be
analyzed by the laboratories for the constituents outlined in Table 1.
4.2 Laboratory Reporting
Laboratory reporting limits (RLs) and method detection limits (MDLs) used by the selected North
Carolina -certified laboratory for methods will meet respective NCDEQ DWM Inactive Hazardous

reported as estimated values and flagged in the laboratory analytical report with a "J". Level II
QA/QC will be reported in the analytical report deliverables.
5. QUALITY ASSURANCE AND QUALITY CONTROL
5.1 Field and Laboratory Procedure QA/QC
One blind duplicate sample of each medium (or one duplicate per 20 samples collected per method)
will be collected and submitted for laboratory analysis. QA/QC will also include measurement of
temperature blanks in each soil sample cooler shipped to the laboratory, analysis of a trip blank in
each sample cooler containing groundwater VOC samples, and documentation of summa canister
vacuum prior to shipment.
5.2 Chain of Custody QA/QC
Geosyntec will initiate chain of custodies for soil, groundwater, soil gas, surface water, and
sediment samples in the field documenting sample collection information including but not limited
to:
• The Sample Collector's Name;
• Project Information and Location;
• Geosyntec Project Manager Contact Information;
• Sample Identification Number;
• Date and Time of Sample Collection;
• Type of Analysis; and
• Type and number of containers and associated preservative, if applicable.
Samples will remain in the custody of Geosyntec until they are ready for shipment. Geosyntec will
relinquish the samples and chain of custodies (noting date and time of relinquishment) to the
laboratory courier who will sign the chain of custody as receiver (noting date and time again).
Geosyntec will retain a copy of the chain of custodies signed by the courier.

Sample coolers and the chain of custodies will be sealed in an appropriate shipping container/box
and sent to the address of the selected laboratory.
A representative from the selected laboratory's sample receiving will sign respective chains of
custody verifying receipt of the samples by each respective laboratory location. A copy of fully
executed chains of custody will be provided in the final laboratory analytical report deliverable.
6. INVESTIGATION DERIVED WASTE (IDW) MANAGEMENT
IDW soil cuttings and development/purge water will be containerized in 55-gallon steel drums and
stored in a designated area of the Site until lab data indicates that material can be safely spread
throughout Site without contaminating property or is required to be disposed off -site. IDW will be
disposed of in general accordance with 15A NCAC 02T.1503 and 15A NCAC 02H. 0106.
7. REPORTING
The results of the soil, groundwater, soil gas, sediment, and surface water sampling will be
summarized in a report to be submitted to the North Carolina Brownfields Program. The report
will include a description of the sampling completed, a tabular summary of validated data
compared to applicable screening criteria, figures depicting sampling locations, QA/QC measures,
soil and well boring logs, and copies of laboratory analytical reports. Analytical results will also
be evaluated using the January 2021 version of the NCDEQ Risk Calculator. The final report will
be signed and sealed by a Professional Engineer or Geologist and will include Geosyntec's
Professional Engineer and Professional Geologist license numbers. If needed, the report will
include recommendations for additional assessment and mitigation measures to minimize human
exposure to contamination. We understand the results of this investigation will be used to evaluate
whether townhome use is acceptable, or whether the Site can be made acceptable for this purpose.
The data will be incorporated into an amended BFA and will be incorporated into a plat map for
the Site which will require a public comment period.
We look forward to your review and approval of this Work Plan and your continued assistance in
pursuing an amended BFA for the Site.
