RE: 1984 Basin Dike Analytical Sampling Results, L.V. Sutton Energy Complex
Dear Ms. Werner:
Duke Energy submits the enclosed report prepared by Geosyntec Consultants of North Carolina, PC
documenting soil results from the former 1984 ash basin dam at the L.V. Sutton Energy Complex.
Sampling deviated slightly from the DEQ approved Work Plan. The Work Plan called for eight cross
sections from the 1984 ash basin dam and two from the 1971 ash basin dam. However, all soils from the
1971 ash basin dam had been excavated and used as fill within the footprint of the former 1984 ash basin.
As such, those two cross sections were relocated to the 1984 ash basin dam. As the analytical totals
results show all constituents are less than the PSRG for protection of groundwater or the site approved
background threshold value, which ever is greater, Duke Energy requests your concurrence to use the
soils from the 1984 ash basin dam as site fill in areas between the former basin and existing landfill.
If you have any questions or need any clarification regarding the information provided, feel free to contact
me at [e-mail] or at 919-546-7863 at your convenience.
Respectfully submitted,

Subject: 1984 Basin Dike Analytical Sampling Results
L.V. Sutton Energy Complex
Sutton Steam Plant Road
Wilmington, North Carolina
Dear Mr. Sylvester:
Geosyntec Consultants of North Carolina, PC (Geosyntec) prepared this Letter Report (Report) to
document the soil sampling activities along the western portion of the 1971 and 1984 Basin dikes
at L.V. Sutton Energy Complex (Sutton), located near Wilmington, North Carolina (NC). Duke
Energy Progress, LLC (Duke Energy) excavated coal combustion residuals (CCR) from the 1984
Basin to support Sutton closure activities. The North Carolina Department of Environmental
Quality (NCDEQ) requires confirmation sampling of the soils from the excavated CCR basin
footprint and basin dikes for use outside the CCR basin footprint. Geosyntec collected soil samples
for visual classification, polarized light microscopy (PLM) laboratory evaluation, and analytical
testing to demonstrate that CCR was removed from within the 1984 Basin footprint. The PLM
test results were presented within the letter report titled "1984 Basin PLM Sampling Results",
dated 16 August 2019, and analytical test results for the 1984 Basin interior will be presented under
separate cover. The purpose of this Report is to describe the site background, soil sampling plan
for dike soils, and analytical testing program, and to present the laboratory results such that
NCDEQ may review and approve the use of dike soils outside the basin footprint.
PURPOSE AND SITE BACKGROUND
CCR at Sutton was historically placed within the 1971 Basin, the 1984 Basin, and the Lay of the
Land Area (LOLA), which are currently being closed through excavation and disposal in an onsite
CCR landfill. The 1971 and 1984 Basin dikes were breached and decommissioned, and dike soils
were generally used to grade and restore the 1984 Basin footprint. However, excess soils in
portions of the CCR basin dikes (i.e., western dikes) will be used to grade and restore areas of the
Sutton property adjacent to but outside of the 1984 Basin footprint.
This Report documents the Geosyntec's investigation to assess the presence of CCR constituents
within the western 1984 Basin dike structures which contained soils proposed for use outside the

1984 Basin footprint. Investigations were generally conducted consistent with the work plan titled
Ash Basin Dam Soil Sampling Work Plan (Sampling Plan) dated 14 August 2019 and approved by
NCDEQ also on 14 August 2019 (Attachment A).
2 METHODOLOGY AND PLAN
The Sampling Plan presents means and methods (e.g., sampling frequency, sample depths,
laboratory requirements) to analyze basin dike soils to identify whether the soils were impacted
or not by prior CCR basin operations such that these soils could be used as `clean fill' outside the
CCR Basin footprint. Specifically, soil sampling was performed as follows:
• The 1971 Basin and 1984 Basin dike section to be sampled was divided into 10 cross
sections;
• soil samples collected at several depth intervals at each cross section, as follows:
0 0 to 0.5 ft bgs, 4 to 4.5 ft bgs, and 7 to 7.5 ft bgs on the both the side slopes;
o approximately 3 to 3.5 ft bgs, 6 to 6.5 ft bgs, and 10 to 10.5 ft bgs on the dike;
• soil samples for each cross section were homogenized and composite samples were
submitted for Total Metals and Synthetic Precipitation Leaching Procedure (SPLP)
analytical tests.
Total Metals and SPLP analytical tests were conducted for the constituents identified in Table 1
of the Sampling Plan.
3 FIELD ACTIVITIES
Geosyntec mobilized to Sutton in August 2019 to collect dike soil samples at each of the proposed
cross sections presented in the Sampling Plan. However, at the time of sampling, the portion of
thel971 Basin dike which was to be sampled was removed and the excavated soil was utilized
within the 1984 Basin footprint. Therefore, the proposed cross sections delineated within in the
Sampling Plan were relocated to the remaining portion of the 1984 Basin. Specifically, the
Sampling Plan proposed two cross sections within the 1971 Basin dike and eight cross sections
within the 1984 Basin dike. However, Cross Sections 9 and 10 were relocated to the 1984 Basin
dike and the 1971-1984 Basin dike intersection, as shown on Figure 1. In addition, the upper 8 feet
of the 1984 Basin dike at Cross Sections 9 and 10 were removed and the soils were utilized within
the 1984 Basin. As such, the sampling intervals were adjusted such that the intermediate and
deeper soil sampling intervals resided within dike soils and not foundation soils.
Geosyntec representatives collected soil samples along the CCR basin dike cross sections for
analytical tests. Hand auger boring coordinates within the western 1984 Basin perimeter dike were
collected using a handheld global positioning system (GPS) unit and are provided in Table 1. The
cross sections derived from the approximate sample locations are depicted in Figure 1. Soil
samples were collected sampled at each boring location using a stainless -steel hand auger. Each
boring was advanced down to the approximate depth of the dike base and soil samples were

collected at target intervals as described in Section 2. Borings were backfilled with auger cuttings
and restored in kind. The stainless -steel hand auger was decontaminated with an Alconox®
solution and rinsed with tap and de -ionized water between each sample interval. The nine soil
samples from each dike cross section were homogenized in a large container to prepare a
composite sample. After visual classification, the composite sample from each section was
packaged within amber, glass soil sample jars, placed within coolers, and iced before a courier
service transported the samples to the Duke Energy Central Laboratory. The container was
decontaminated with an Alconox® solution and rinsed with deionized water between each cross
section.
4 RESULTS
Geosyntec confirmed visually that all surficial CCR was removed prior soil sample collection.
After sample collection, Geosyntec submitted the 10 composite soil samples (i.e., one composite
sample per cross section location) to the laboratory to be tested for Total Metals content (in terms
of milligrams per kilogram, mg/kg) and SPLP (in terms of milligrams per liter, mg/L, or
micrograms per liter, ug/L) analytical tests for the constituent list provided within Table 1 of
Attachment A. Meanwhile, as -received laboratory test results are provided in Attachment B to
this Report. Geosyntec summarized the received test results within Table 2 and compared the
measured concentrations for constituents of interest with their May 2019 Groundwater Protection
Preliminary Soil Remediation Goals (PSRGs), May 2019 Industrial/Commercial PSRGs, and the
Background Threshold Values (BTVs)l established for Sutton. The analytical test results
identified all constituents of interest to be below their respective Industrial/Commercial and
Groundwater Protection PSRGs, except for Iron and Cobalt. Iron concentrations were found to
range between 570 mg/kg and 2,400 mg/kg, which is below the BTV at Sutton of 2,750 mg/kg.
The Cobalt concentration was found to be 1.1 mg/kg at one of the dike sections (i.e., 84D-10),
which was above the Groundwater Protection PSRG (0.9 mg/kg) and the BTV (0.89 mg/kg) for
Cobalt. SPLP test results are summarized in Table 3 and as -received data is provided in Attachment
B.

New Hanover County
FID 1339437
Dear Mr. Toepfer:
The Solid Waste Section (Section) has reviewed the Ash Basin Dam Soil Sampling Work Plan (FID
1339436) at the Sutton Energy Complex submitted on August 14, 2019. The purpose of the
work plan is to determine if approximately 120,000 cubic yards of soil within the dams can be
used along the existing transmission corridor between the ash basins and onsite landfill outside
the footprint of the ash basins. The work plan proposes to take eight (8) soil samples along the
1984 basin dam and two (2) soil samples along the 1971 basin dam. At each sample location,
nine (9) distinct samples will be collected and mixed into one composite sample. The ten (10)
composite samples will be analyzed for total metals and leachability using the synthetic
precipitation leaching procedure (SPLP).
The Section approves the soil sampling work plan.

Duke Energy (Duke) submits the Ash Basin Dam Soil Sampling Work Plan for the L.V. Sutton Energy Complex.
The majority of the soil comprising the former 1984 and 1971 ash basin dams will be regraded within the
footprint of the former ash basins. However, there is excess soil and Duke proposes to use the soils from a
portion of the dams as fill in the existing transmission corridor located onsite between the former basin and
existing landfill. Per prior discussions via telephone, Duke proposes to collect 10 composite soil samples from
10 different dam cross -sections for analysis.
If you have any questions or need any clarification regarding the information provided, feel free to contact
me at [e-mail] or at 919-546-7863 at your convenience.
Respectfully submitted,

Ash Basin Dam Soil Sampling Plan
August, 2019
L.V. Sutton Energy Complex
1.0 PURPOSE
The purpose of this Soil Sampling Work Plan is to provide a method for collecting and analyzing soil
samples from the 1984 and 1971 ash basin dams at the L.V. Sutton Energy Complex. All ash has been
removed from the 1984 and 1971 ash basins and the dams are in process of decommissioning. The
majority of the dams will be regraded within the footprint of the former ash basins. However, there is
approximately 120,000 cubic yards of excess soils that will be used as fill within the existing transmission
corridor located between the former ash basins and the existing landfill. As Duke Energy plans to utilize
this excess soil onsite, sampling is necessary to ensure the soil will not present secondary source
contamination. This Soil Sampling Work Plan is applicable to the collection of representative soil
samples and analysis of soil samples will be used to determine the presence or absence of constituents.
2.0 SOIL SAMPLING METHODOLOGY
2.1 Method Summary
This Soil Sampling Work Plan has been adapted from Environmental Protection Agency (EPA) Standard
Operating Procedures (SOPS) #2012 and #2006.
Soil samples are collected using a plastic trowel, spade, shovel, or scoops along with hand auger and drill
rig for samples collected at depths below 6 inches. Following collection, soil is transferred from the
sampling device to a plastic bowl to be homogenized. Once homogenized, the soils (composite) will be
transferred into Duke Energy Laboratory supplied sample bottles.
Soil samples will be submitted under chain of custody for the following analyses: total metals and
Synthetic Precipitation Leaching Procedure(SPLP) metals. Analytical methods for total metals and SPLP
metals are described in Table 1.
Equipment
• Sample bottles/containers —To be supplied by Duke Energy Laboratory with
appropriate cooler(s). Estimated that up to five 8-ounce sample bottles with Teflon -
lined lids will be required for each soil sample. For return of cooler to the lab, ice will
be required.
• Gloves — used for personal protection and to prevent cross -contamination of samples —
nitrile, disposable, powderless.
• Field clothing and Personal Protective Equipment — used as specified in the site Health
and Safety Plan.
• Sampling flags —used for identifyingsoil sampling locations.
• Field notebook —a bound book used to record progress of sampling effort and record
any problems and field observations during sampling.

August, 2019
L.V. Sutton Energy Complex
• Three-ring binder/book — used to store necessary forms and record and track samples
collected at the site.
• Permanent marking pen — used to label sample containers, document field logbooks,
data sheets and chain of custody.
• Plastic spoon — used for homogenizing soil samples within a plastic bowl.
• Plastic bowl —used for homogenizing soil samples, when applicable.
• Camera — used for photo -documentation of sample locations and samples.
• Trash bag — used to dispose of gloves and any other non -hazardous waste generated
duringsampling.
• Decontamination supplies and equipment.
2.1.1 Collection of Representative Samples
All sampling equipment will be decontaminated prior to use. The following procedure will be
used to collect each soil sample at each of the ten proposed cross -sections:
• Locate general sampling locations and record coordinates with a GPS unit.
Collect a soil column at each designated sampling location via drill rig, hand
auger or plastic spoon/trowel or shovel. Combine samples from each cross-
section location within a sample (Shown in Figure 1) mixing bowl and
thoroughly mix.
• Transferto the sample bottles and secure sample bottles tightly.
2.1.2 Sample Preservation, Containers, Handling and Storage
Chemical preservation of soils is generally not recommended. Cooling to 4°C on wet ice is
usually the best approach, supplemented by the appropriate holding time for the analyses
requested.
The Duke Energy Laboratory will supply the appropriate sample bottles for the collected soil
samples. The sample volume is a function of the analytical requirements and the Duke Energy
Laboratory will ensure the appropriate number of bottles are supplied. Ensure chain of custody
is completed for sample bottle return to the Duke Energy Laboratory.
Table 1 contains a list of parameters to be analyzed with corresponding reporting units and
analytical methods. If a parameter or group of parameters is not included in Table 1, the
laboratory performing the analysis should be contacted to determine the appropriate sample
bottles, volumes, and preservatives.
All non -dedicated sampling devices should be decontaminated and wrapped in plastic. The
sampling device should remain in this wrapping until it is needed. Each sampling device should

be used for only one sample and then decontaminated or disposed of. Non -dedicated sampling
devices should be cleaned in the field using the decontamination procedure described below.
2.1.3 Decontamination
Decontamination procedures can be time consuming; having a sufficient quantity of sampling
tools available is recommended. All non -dedicated sampling equipment must be
decontaminated prior to reuse. Equipment decontamination consists of:
1. Detergentwash and brush cleaning
2. Tap water rinse
3. De -ionized water rinse
4. Air dry
5. Wrap sampling tools with plastic
3.0 SOIL SAMPLING AND ANALYSIS
3.1 Soil Sampling
Sample locations will be collected in a manner similar to UST Guidelines for Sampling. At each
of the ten cross -sections, samples will be collected from the mid -point of the upstream face of
dam, the center top of dam and the mid -point of the downstream face of the dam.
The 1984 ash basin dam is approximately 16 feet in height. The 1971 ash basin dam is not
nearly as tall. The below listed sampling depths are based upon the 1984 ash basin. Depths
from the 1971 ash basin dam will be determined in the field but will still consist of collecting 3
different sampling depths at each of the 3 sampling locations per cross-section.
Mid -point upstream face (8 feet above basin floor)
0-6 inches
4-4.5 feet
7-7.5 feet
Center top of dam (16 feet above basin floor)
3-3.5 feet
6-6.5 feet
10-10.5 feet
Mid -point downstream face (8 feet above basin floor)
0-6 inches
4-4.5 feet
7-7.5 feet

Ash Basin Dam Soil Sampling Plan
L.V. Sutton Energy Complex
August, 2019
Therefore, at each cross-section, nine individual samples will be collected and homogenized
together and result in one composite soil sample for laboratory analysis. There will be 10 cross -
sections total as shown in Figure 1.
3.2 Sample Analysis
The ten composite samples will be sent to the Duke Energy Laboratory for analysis of total
metals and SPLP metals. The lab will test for the inorganic compounds listed in Table 1. The
results will be compared to site background levels, along with the current Protection of
Groundwater Preliminary Soil Remediation Goals (PSRG) and the Industrial/Commercial PSRG
set forth by NCDEQ. If the 10 sample results for total metals do not exceed the Protection of
Groundwater PSRG and/or site background (which ever is greater), then NCDEQ Division of
Waste Management, Solid Waste Section will be notified and the soil will be used as general fill
onsite within the transmission corridor between the former ash basin and landfill.
4.0 DOCUMENTATION
A comprehensive report will be submitted to NCDEQ Division of Waste Management, Solid
Waste Section and include the associated lab reports. If an exceedance is found when data is
compared to background and/or PSRG for Protection of Groundwater, then Duke Energy will
discuss further action and/or additional sampling plans with NCDEQ.

Please review all vendor data for case narratives with explanations of quality control failures and data qualifiers.
Any analytical tests or individual analytes within a test flagged with a qualifier indicate a deviation from the method quality
system or quality control requirement. Certified vendor results and QC qualifiers can be found in the vendor lab final report.
This report shall not be reproduced, except in full, without the written consent of the Analytical Laboratory.
Vendor Data Review Criteria:
This vendor data package has been reviewed at the Duke Analytical Laboratory for the following applicable criteria:
• Required QC samples collected and analyzed
• Required tests performed for all samples
• Vendor Laboratory utilized required test methods for all analyses
• Vendor Laboratory met all requested Reporting Limits (RL)
• QC Results reviewed for outlying recovery values
Case Narrative:
Method: 9045D pH
The pH analysis were performed after the method recommended 15 minute holding time.
Method: EPA 9056A Chloride
Chloride was detected at a concentration above the DL and below the LOQ in the MB associated with all samples.
Method: EPA 9056A SPLP Nitrate-N
The MS and MSD associated with samples: 84D-1 and 84D-2 recovered outside acceptance criteria for Nitrate. Since the LCS
and MB were within control limits it was determined that matrix interference caused the MS and MSD to fail.

Case Narrative
Duke Energy
Lot Number: UH22084
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality
Assurance Management Plan (QAMP), standard operating procedures (SOPS), and Shealy policies. Any
exceptions to the NELAC standards, the QAMP, SOPS or policies are qualified on the results page or
discussed below.
Where applicable, all soil sample analysis are reported on a dry weight basis unless flagged with a "W"
qualifier.
The pH analysis associated with the sample(s) in this report was/were performed after the method
recommended 15 minute holding time.
Chloride (soluble) Analysis 9056A
The method blank associated with batch 27612 had chloride detected at a concentration that was
above the DL and below the LOQ. All samples associated with this method blank that have detections for
chloride have been flagged with a "B".
SPLP Nitrate-N Analysis 9056A
Nitrate recovered outside the control limit in the MS/MSD batch 28358 associated with sample -001.
Since the LCS and Method Blank were within control limits it was determined that matrix interference
caused the MS/MSD to fail.
The nitrate MS/MSD was redone using sample -002 and nitrate also recovered outside the control limit in
the MS/MSD batch 28358 associated with sample -002. Since the LCS and Method Blank were within
control limits it was determined that matrix interference caused the MS/MSD to fail.
If you have any questions regarding this report please contact the Shealy Project Manager listed on the
cover page.
