In accordance with the landfill Environmental Control Monitoring Plan, Duke Energy is providing the results of
semi-annual leachate and underdrain sampling and leak detection system monitoring results for the Marshall
Steam Station Industrial Landfill No. 1, located in Terrell, North Carolina.
On August 9, 2023, leachate samples were collected from Phase 1, Phase 2, the leachate basin and an
underdrain sample was collected from Cell 5. The samples were collected by Pace Analytical and analyzed by
the Duke Energy Analytical Laboratory. A summary of sampling results can be found in the attached report
along with the leak detection system monitoring results. The parameters tested are not bound by state
groundwater or surface water standards. The leachate is conveyed to the Station's lined retention basin, which
discharges via a NPDES permitted outfall. All laboratory analytical and field results are provided in the
Appendices.
Marshall Steam Station's Industrial Landfill No. 1 is sampled semi-annually during August and February. The
next landfill sampling event will occur February 2024 with documentation to follow.

Environmental Controls Monitoring Plan Semiannual Report March 2023 through August 2023
Industrial Landfill No. 1 1812-INDUS
1.0 Background
This Environmental Controls Monitoring Plan Semiannual Report is for the Industrial Landfill No. 1 —
Phase 1 (Cells 1 through 4), Phase 2 (Cells 5 and 6 and underdrain), and the Leachate Basin(1812-
INDUS) located at the Duke Energy Carolinas, LLC (Duke Energy) Marshall Steam Station (Marshall,
Plant, or Site). Monitoring results in this report are from the period of March 2023 through August 2023.
The Environmental Controls Monitoring Plan (ECMP) establishes locations and procedures for
monitoring early detection of solid waste or leachate potentially released to the environment from
Industrial Landfill No. 1 (landfill). The ECMP, Revision 3 (SynTerra, 2022) was submitted to the North
Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM) on
December 13, 2021, and was approved by the DWM on December 14, 2021. The August 2023
sampling event and this report comply with the ECMP, Revision 3 (SynTerra, 2022). In October 2023,
the ECMP, Revision 4 was submitted to the NCDEQ but has not yet been approved; therefore, that
revision is not relevant to this sampling event.
The landfill is designed and constructed in accordance with North Carolina General Statute (NCGS)
130A § 295.4 for Combustion Products Landfills. This report is intended to satisfy the water quality
monitoring plan required by North Carolina Administrative Code (NCAC) Title 15A Subchapter 13B
.0504(c)(8)(D) in accordance with NCGS 130A § 295.4(c).
1.1 Site Description
Additional Site description information can be found in Section 1.1 of the ECMP.
1.1.1 Landfill
The approximately 67.1-acre landfill (Phase 1 and 2) is located north of the Marshall
power block and generally bounded by the Duke Energy property line to the north;
vacant land and the closed asbestos and construction and demolition (C&D) debris
landfill areas (1804-INDUS) to the east; and the PV Structural Fill (CCB0031), and the
historic ash basin to the south and west (Drawing 1). Phase 1 of the landfill is
approximately 35.5 acres and is currently operating. Phase 2 of the landfill is
approximately 31.6 acres and is currently under construction as part of the landfill
expansion; Cells 5 and 6 began operations in 2022 and 2023, respectively.
The engineered base liner system of the landfill is designed and constructed with a
leachate collection and removal system above the primary liner and a leak detection
system (LDS) to monitor the performance of the primary liner to prevent a release to the
environment.
Phase 1 of the landfill is divided into four cells (Cell 1, Cell 2, Cell 3, and Cell 4). Phase 2
of the landfill is divided into two cells (Cell 5 and Cell 6). Each cell has a discrete low
area (sump) where the LDS is monitored and leachate is collected for removal from the
landfill by mechanical pumping.
The majority of waste intended for placement throughout the life of the landfill consists of
coal combustion residuals (CCR), predominantly fly ash and bottom ash. The approved
waste streams can be found in the Operations Plan (AECOM, 2020).

Environmental Controls Monitoring Plan Semiannual Report March 2023 through August 2023
Industrial Landfill No. 1 1812-INDUS
1.1.2 Leachate Basin
The landfill leachate basin began operation at Marshall in summer of 2023; the leachate
basin was constructed with the Industrial Landfill No. 1, Phase 2 expansion.
Leachate is conveyed from the landfill to the leachate basin for a temporary holding,
from the leachate basin the leachate is conveyed to the lined retention basin (LRB)
where it is commingled with other Plant low -volume wastewater for treatment. Flows
from the LRB are discharged to Lake Norman through outfall 005 in accordance with
National Pollutant Discharge Elimination System (NPDES) Permit NC0004987 (Drawing
2).
1.1.3 Underdrain
Phase 1 of the landfill is not constructed with an underdrain.
Phase 2 of the landfill is constructed with a blanket underdrain located in the western
portion of the landfill phase (Drawing 2). The underdrain only underlies Cell 5 of Phase
2. The underdrain is composed of a 2-foot layer of crushed stone aggregate with
perforated pipes connecting to a common sump area for liquid removal by pumping. The
top of the underdrain is 4 feet below the base of the compacted soil liner elevation.
Construction completion and startup operations of the underdrain began in October
2021.
1.1.4 Surface Water
Landfill area stormwater is directed via channels around the perimeter of the landfill to
an NPDES-permitted wastewater unit or NPDES-permitted outfall.
1.2 Summary of Site Geology and Hydrology
The landfill is partially situated within an area that was formerly used for the storage or
disposal of CCR, including the historic ash basin and structural fill (CCB0072) (Landfill Phase I
Subgrade) (Drawing 1).
The landfill, ash basin, closed historic landfills, and structural fills are contained within a former
perennial stream valley (flow compartment). Groundwater within the flow compartment is a
flow -through system. Groundwater enters the system from the upgradient end near the landfill
and flows laterally through the middle regions and downward near the dam, or downgradient
end. Groundwater divides are located west and north of the landfill, concurrent with
topographic ridges along Sherrills Ford Road to the west and Island Point Road to the north.
The primary flow path of the groundwater is northwest to southeast within the flow
compartment. The topographically controlled flow direction provides natural hydraulic control
of constituent migration from the ash basin and adjacent unlined sources within the flow
compartment.
Groundwater downgradient of the landfill is unable to be monitored independently from the ash
basin, closed historic landfills, and structural fills within the same flow compartment because
those sources have historically been used to store or dispose of the predominant material in
the landfill (CCR).
Additional Site geology and hydrology information can be found in Section 1.2 of the ECMP.

Industrial Landfill No. 1 1812-INDUS
2.0 Monitoring, Sampling, and Analysis Locations and Methods
2.1 Leak Detection System Monitoring
Leak detection monitoring occurs in the vicinity of each landfill and leachate basin sump
identified as:
• MSS-LF-LDS1 • MSS-LF-LDS2
• MSS-LF-LDS3 • MSS-LF-LDS4
• MSS-LF-LDS5 • MSS-LF-LDS6
• MSS -LB -LDS
LDS identification numbers each correspond to a landfill cell (Cell 1 through Cell 6). The
general location of each LDS monitoring location is shown on Drawing 2.
Performance of the LDS is determined by the average monthly quantity of liquid removed from
the leak detection layer. Each landfill cell leak detection discharge pump is equipped with a
pump totalizer (flow meter). The flow meter rates were monitored and recorded as defined in
the Operations Plan (AECOM, 2020).
Leak detection monitoring results are summarized in Section 3.0.
2.2 Leachate Sampling and Analysis
Leachate samples collected in the vicinity of each landfill sump from the leachate collection
system (LCS) discharge are identified as:
• MSS-LF-LCS1
• MSS-LF-LCS3
• MSS-LF-LCS5
• MSS-LF-LCSC1
• MSS-LF-LCS2
• MSS-LF-LCS4
• MSS-LF-LCS6
The identification numbers correspond to the landfill cells (Cell 1 through Cell 6 and Leachate
Basin). The general location of each leachate monitoring location is shown on Drawing 2.
Discrete leachate samples, from in -line valves, were collected from locations MSS-LF-LCS1
through MSS-LF-LCS6 and MSS-LF-LCSC1 on August 9, 2023. Pace Analytical personnel
(North Carolina Field Certification #5342) collected samples and documented the sampling
event in accordance with procedures provided in Duke Energy's Landfill Sample Collection
Guideline (ECMP Appendix 1).
Copies of the field calibration and sampling forms are included in Appendix A. The
parameters and constituents reported were sampled in accordance with Table 1 of the
approved ECMP. Constituents were analyzed by Duke Energy Analytical Laboratory (North
Carolina Laboratory Certification #248). The laboratory report and chain -of -custody (COC)
forms are included in Appendix B.

• Chloride, fluoride, nitrate (as nitrogen), and sulfate using USEPA Method 9056A
Total dissolved solids using Standard Method (SM) 2540CLeachate field parameters and
analytical results are summarized in Section 3.0.
2.3 Underdrain Outlet Sampling and Analysis
A discrete underdrain sample was collected from the MSS-LF-UD1 location on August 9,
2023. Pace Analytical personnel collected samples and documented the sampling event in
accordance with procedures provided in Duke Energy's Landfill Sample Collection Guideline
(ECMP Appendix 1).
Copies of the field calibration and sampling form are included in Appendix A. The parameters
and constituents reported were sampled in accordance with Table 1 of the approved ECMP.
Duke Energy Analytical Laboratory analyzed the constituents; the laboratory report and COC
forms are included in Appendix B.
The underdrain sample was measured for the same set of in situ parameters and constituents
as the leachate samples as listed in Section 2.2.
Underdrain field parameters and analytical results are summarized in Section 3.0.
2.4 Surface Water Sampling and Analysis
Surface water sampling is currently not required for the landfill.

Environmental Controls Monitoring Plan Semiannual Report March 2023 through August 2023
Industrial Landfill No. 1 1812-INDUS
3.0 Monitoring, Sampling, and Analysis Results
3.1 Leak Detection System Monitoring Results
No exceedances of the Initial Response Leakage Rate (IRLR) and Action Leakage Rate (ALR)
are identified for the reporting period.
Each month, an average daily leakage rate is calculated for each operational landfill cell (Cell
1 through Cell 6) and compared to the IRLR and ALR for the landfill LDS as defined in the
Operations Plan (AECOM, 2020).
Average daily leakage rates for Cell 1 through Cell 6 were calculated as follows:
1. Calculate the monthly total volume pumped (gallons):
monthly volume pumped (gallons) = current month total flow meter reading — preceding
month total flow meter reading
2. Calculate the average daily leakage rate [gallons per acre per day (gpad)]:
average daily leakage rate (gpad) = monthly volume pumped (gallons) - landfill cell area
(acres) = monitoring duration (days)
The LDS monitoring results for locations MSS-LF-LDS1 through MSS-LF-LDS6 and MSS -LB -
LDS are included in Table 1A through Table 1G. The LDS leakage rate data collection details
are kept with onsite records.
No leakage rates were outside of the normal range for the landfill.
3.2 Leachate Field and Analytical Results
Leachate analytical results are not compared to water quality standards.
The leachate field and analytical results for samples MSS-LF-LCS1 through MSS-LF-LCS6
and MSS-LF-LCSC1 are included in Table 2.
Select samples were diluted, as is normal laboratory practice, to bring samples within the
calibrated range of analysis. Specifics regarding the samples that were diluted, including the
dilution factor, are reported in the EDD and the laboratory analytical report. The laboratory
analytical report, data validation checklist, and chain -of -custody form associated with data
collected as part of this semiannual monitoring period are included in Appendix B.
3.3 Underdrain Outlet Analytical Results
Underdrain analytical results are not compared to water quality standards.
The underdrain field and analytical results for sample MSS-LF-UD1 are included in Table 3.
Page 5

Environmental Controls Monitoring Plan Semiannual Report March 2023 through August 2023

The underdrain sample is included in the same laboratory analytical report, data validation
checklist, and chain -of -custody form as the leachate data collected as part of this semiannual
monitoring period (Appendix B).
3.4 Surface Water Analytical Results
Surface water sampling is currently not required for the landfill; therefore, there are no
analytical results to report.

The questions on this checklist refer to basic review of laboratory analytical reports for completeness and accuracy of data. Any responses requiring follow up action with the analytical lab or field personnel must be
noted in the summary section at the end of this form before the data can be approved for use by technical leads.
Lab Qualifiers:
J-Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
7
M - MS and/or MSD recovery was outside of the control limits; the associated LCS recovery was acceptable.
M4 -The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level; the associated LCS recovery was acceptable.
U-Analyte was analyzed for, but not detected above the MDL.
Validation Qualifiers:
R- Result is unusable. The sample result is rejected due to serious deficiencies in meeting quality control criteria; the analyte may or may not be present in the sample.
J - Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
U-Analyte was analyzed form but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B -Target analyte detected in the method blank an in the sample at a concentration less than 10x the blank concentration.
• Chloride MS/MSD % recoveries low and Sulfate MS/MSD % recoveries high for ILF1-LCS-CELLl (M4).
• Mercury MS/MSD % recoveries low for ILF1-LCS-CELLl (M).
• Calcium and Magnesium MSD % recoveries low (MSs ok) for ILFl-LCS-CELL1(M4).
• The RPD between ILF1-LCS-CELL6 and the field duplicate is greater than 35%for Iron (0.276/0.665 mg/L), Manganese (0.008/0.015 mg/L), Boron (0.062/0.022 mg/L), Calcium (11.4/7.40 mg/L),
Chromium (1.90/0.506 ug/L), Vanadium (0.856/1.75 ug/L), Sulfate (11/7.5 mg/L), Nitrate (0.19/0.27 mg/L), Nitrate as N (0.04/0.06 mg/L), and TDS (44.0/29.0 mg/L).
• Boron (0.01 mg/L) and Calcium (0.015 mg/L) were detected in the Field Blank; Boron was also detected in the samples at concentrations less than 10x the blank concentration.

Qualifiers:
J Analyte detected above the MDL, but below the RL. Analyte concentration should be considered an estimate.
M Matrix Spike and/or Matrix Spike Duplicate recovery was outside of the control limits. The associated Laboratory Control
Spike (LCS) recovery was acceptable.
M4 The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level.
The associated Laboratory Control Spike recovery was acceptable.
