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 February 13, 2025, 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 August 2025 with documentation to follow.

Environmental Controls Monitoring Plan Semiannual Report September 2024 through February 2025
Industrial Landfill No. 1 (Permit No. 1812-INDUS)
1.0 Background
This Environmental Controls Monitoring Plan Semiannual Report is for the Industrial Landfill No. 1 (ILF
or landfill; Permit No. 1812 INDUS)—including Phase 1 (Cells 1 through 4) and Phase 2 (Cells 5 and 6
and underdrain)—and the Leachate Basin, located at the Duke Energy Carolinas, LLC (Duke Energy)
Marshall Steam Station (Marshall, Plant, or Site). Monitoring results in this report are from September
2024 through February 2025.
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
landfill. The ECMP, Revision 5 (SynTerra, 2024) was submitted to the North Carolina Department of
Environmental Quality (NCDEQ) Division of Waste Management (DWM) on November 6, 2024, and
was approved by the DWM. The February 2025 sampling event and this report comply with the ECMP,
Revision 5 (SynTerra, 2024).
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 Revision 5
(SynTerra, 2024).
1.1.1 Landfill
The 67.1-acre landfill (Phase 1 and 2) is located north of the Marshall power block and is
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 (Permit No. 1804-
INDUS) to the southeast; and the coal combustion residuals (CCR) Structural Fill
CCB0031 (previously known as the Photovoltaic Structural Fill) to the west and
southwest. The landfill overlies the historical ash basin to the south, and Future Phase 5
to the southwest will partially overlie the MAR-145 industrial stormwater pond.
(Drawing 1).
Phase 1 of the landfill is approximately 35.5 acres, and Phase 2 of the landfill is
approximately 31.6 acres. Both Phase 1 and 2 are currently operating. Phases 3 and 4
are under construction but not operational. Construction has not begun on Future Phase
5. Therefore, those phases will not be discussed in this report. The DWM issued the
initial Permit to Operate on March 7, 2011. Phase 1 of the landfill is constructed over the
CCR Structural Fill CCB0072 (Landfill Phase I Subgrade). Phase 2 of the landfill is
immediately south of Phase 1. Phase 1, Phase 2, and Structural Fill CCB0072 are
situated adjacent to and partially over an upstream area of the historical ash basin waste
boundary (Drawing 2).
Operational flows from the CCR Structural Fill (CCB0031) stability feature dewatering
systems are temporarily routed to the leachate basin; those flows started in the third
quarter of 2024. In addition, an in -line caustic treatment and static mixer were installed at
the leachate basin in the fourth quarter of 2024 to provide additional pH treatment prior
to discharge into the leachate basin. The caustic treatment system was commissioned in
May 2025.

Environmental Controls Monitoring Plan Semiannual Report September 2024 through February 2025
Industrial Landfill No. 1 (Permit No. 1812-INDUS)
The landfill, in accordance with NCGS 130A § 295.4(b), is constructed with a base liner
system that includes a primary and secondary geomembrane liner. The primary and
secondary liners are separated by a geocomposite drainage layer to create a leak
detection layer. The geocomposite provides enough capacity to convey liquid that enters
the leak detection layer to a sump area (lowest elevation in an area of the liner system)
where it is collected for removal by mechanical pumping. Removal of liquid from the leak
detection layer, in addition to the combination of a geosynthetic clay liner (GCL) and
compacted soil liner beneath the secondary liner, reduces the potential for liquid to enter
the environment. The quantity of liquid removed from the leak detection layer is
measured and recorded.
Each phase of the landfill is divided into cells. Each cell has a sump where the leak
detection system (LDS) is monitored, and leachate is collected for removal from the
landfill by mechanical pumping. A network of drainage features manages stormwater
from the landfill and adjacent area, which is routed to a permitted outfall. No stormwater
from the landfill area flows off the Site property or enters surface water prior to passing
through a permitted outfall.
The historical ash basin, which partially underlies the landfill and is adjacent to the
leachate basin, received CCR via sluice lines beginning in 1965 until early 2019. In
1984, Marshall converted from wet to dry fly ash handling. In 2019, bottom ash was
converted from wet to dry handling and ash sluicing ceased. Duke Energy is authorized
to discharge wastewater from the ash basin to Lake Norman (Outfall 005) in accordance
with National Pollutant Discharge Elimination System (NPDES) Permit NC0004987.
Most of the waste intended for placement throughout the life of the landfill consists of
CCR, predominantly fly ash and bottom ash. The approved waste stream can be found
in the Operations Plan (AECOM, 2020).
1.1.2 Leachate Basin
The landfill leachate basin began operation in July 2023; the leachate basin was
constructed with the ILF Phase 2 expansion.
The leachate basin is located south of the ILF and is bounded by the historical ash basin
to the north, east, and south and the CCR Structural Fill CCB0031 to the west and
southwest (Drawing 2). The leachate basin, in accordance with NCAC, Title 15A,
Subchapter 13B .1680(e)(2), is constructed with a base liner system that includes a
primary and secondary geomembrane liner. The primary and secondary liners are
separated by a geocomposite drainage layer to create a leak detection layer. The
geocomposite provides enough capacity to convey liquid that enters the leak detection
layer to a sump area where it is collected for removal by mechanical pumping. Removal
of liquid from the leak detection layer, in addition to the combination of a GCL and
compacted soil liner beneath the secondary liner, reduces the potential for liquid to
release into the environment. The quantity of liquid removed from the leak detection
layer is measured and recorded. The leachate basin engineered base liners include an
LDS that monitors the integrity of the primary flexible membrane liner.
The leachate of Phases 1 and 2 is conveyed from the landfill to the leachate basin via a
force main piping network. The leachate basin discharges to the Lined Retention Basin
(LRB) where it is comingled with other Plant low -volume wastewater for treatment. The
LRB discharges to Lake Norman through Outfall 005 in accordance with NPDES Permit
NC0004987 (Drawing 2).

Industrial Landfill No. 1 (Permit No. 1812-INDUS)
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 groundwater system in the natural materials (shallow, deep, and bedrock flow zones) at
Marshall is consistent with the regolith-fractured rock system and is characterized as an
unconfined, interconnected aquifer system indicative of the Piedmont physiographic province
in which the Site is contained. The groundwater system at the Site is divided into the following
three layers to distinguish the interconnected groundwater system: the shallow flow zone,
deep (transition zone) flow zone, and the bedrock (competent bedrock) flow zone.
The landfill is partially situated within an area that was formerly used for the storage or
disposal of CCR, including the historical ash basin, and beneficial reuse of CCR, including the
Structural Fill (CCB0072) (Landfill Phase I Subgrade) (Drawing 1).
The landfill, ash basin, closed historical 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 historical 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
Revision 5 (SynTerra, 2024).

Industrial Landfill No. 1 (Permit No. 1812-INDUS)
2.0 Monitoring, Sampling, and Analysis Locations and Methods
2.1 Leak Detection System Monitoring
Leak detection monitoring occurs at the leachate basin (MSS -LB -LDS) and at each landfill
sump identified as:
• MSS ILF1-LDS-CELL1
• MSS ILF1-LDS-CELL2
• MSS ILF1-LDS-CELL3
• MSS ILF1-LDS-CELL4
• MSS ILF1-LDS-CELL5
• MSS ILF1-LDS-CELL6
LDS identification numbers each correspond to a landfill cell (Cell 1 through Cell 6 and the
leachate basin). The 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, 2022). In October 2024, however, the pump totalizer
experienced a temporary outage. Therefore, the reported monthly gallons pumped were based
upon manual readings taken on October 1, 2024 (Table 1).
Leak detection monitoring results are summarized in Section 3.0.
2.2 Leachate Sampling and Analysis
Leachate samples are collected at the leachate basin at:
• MSS-ILF1-LCSC1.
Leachate samples are also collected near the landfill sump from the leachate collection system
(LCS) discharge at the following locations:
• MSS ILF1-LCS-CELL1
• MSS ILF1-LCS-CELL2
• MSS ILF1-LCS-CELL3
• MSS ILF1-LCS-CELL4
• MSS ILF1-LCS-CELL5
• MSS ILF1-LCS-CELL6
The identification numbers correspond to the landfill cells (Cell 1 through Cell 6 and Leachate
Basin). The location of each leachate monitoring location is shown on Drawing 2.
Discrete leachate samples, from in -line valves, were collected from locations MSS _ILF1-LCS-
CELL1 through MSS _ILF1-LCS-CELL6 and MSS-ILF1-LCSC1 on February 13, 2025. 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 Revision 3, Appendix I; SynTerra, 2022).
Copies of the field calibration and sampling forms are included in Appendix A. The
parameters and constituents reported were sampled in accordance with the ECMP Revision 3
and the harmonized constituent list approved by NCDEQ on March 20, 2023. The Duke
Energy Analytical Laboratory (North Carolina Laboratory Certification #248) analyzed the
Page 4

Industrial Landfill No. 1 (Permit No. 1812-INDUS)
constituents. The laboratory report and chain -of -custody (COC) forms are included in
Appendix B.
The leachate samples were measured for the following field parameters:
• pH, specific conductivity, temperature, dissolved oxygen, and oxidation-reduction
potential using a water quality meter
• Turbidity using a turbidity meter
The leachate samples were analyzed for the following constituents:
• Barium, boron, calcium, iron, lithium, magnesium, manganese, and zinc using U.S.
Environmental Protection Agency (USEPA) Method 200.7/SW 6010D
• Antimony, arsenic, beryllium, cadmium, chromium, cobalt, copper, lead, molybdenum,
nickel, selenium, thallium, and vanadium using USEPA Method 200.8/SW 6020B
• Silver using USEPA Method 200.8/SW 6020A
• Mercury using USEPA Method 245.1/SW 7470A
• Chloride, fluoride, nitrate (as nitrogen), and sulfate using USEPA Method 300.0/SW
9056A
• Total dissolved solids using Standard Method (SM) 2540C/EPA 160.1/ ASTM D5907
Leachate 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 _ILF1-UD1 location on February 13,
2025 (Drawing 2). Pace Analytical personnel collected samples and documented the
sampling event in accordance with procedures provided in Duke Energy's Landfill Sample
Collection Guideline (ECMP Revision 5, Appendix I; SynTerra, 2024).
Copies of the field calibration and sampling form are included in Appendix A. The parameters
and constituents reported were sampled in accordance with the ECMP Revision 5 and
harmonized constituent list approved by NCDEQ on March 20, 2023. 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 field parameters and constituents
as the leachate samples (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.

3.0 Monitoring, Sampling, and Analysis Results
3.1 Leak Detection System Monitoring Results
Leakage rates were less than the Initial Response Leakage Rate (IRLR) and Action Leakage
Rate (ALR) during the reporting period.
Each month, an average daily leakage rate is calculated for each operational landfill cell (Cell
1 through Cell 6) and the leachate basin and compared to the IRLR and ALR for the landfill
LDS, as defined in the Operations Plan (AECOM, 2022).
Average daily leakage rates for Cell 1 through Cell 6 and the leachate basin 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 MISS _ILF1-LDS-CELL1 through MISS _ILF1-LDS-
CELL6 and the leachate basin LDS are included in Table 1A through Table 1G. The LDS
leakage rate data collection details are kept with on -Site records.
No leakage rates were outside of the normal range for the landfill; however, during the
reporting period, a pump and instrumentation control panel outage did occur. These have
been resolved and manual measurements confirmed that no leakage rates beyond the normal
range occurred.
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 MISS _ILF1-LCS-CELL1 through
MSS ILF1-LCS-CELL6 and MSS-ILF1-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_ILF1-UD1 are included in Table 3.
Page 3

Environmental Controls Monitoring Plan Semiannual Report September 2024 through February 2025
Industrial Landfill No. 1 (Permit No. 1812-INDUS)
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.

❑ ❑ 15) Were any reporting limits for diluted, non -detect results greater than the screening criteria?
❑� 16) Radionuclides: Are quality control sample results provided?
�J a) Are any results flagged or qualified?
�J b) Are Uncertainty, Minimum Detectable Concentration (MDC), and Tracer and/or Carrier % Recoveries provided for each sample?
Lab Qualifiers:
1 - Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
M - MS and/or MSD recovery was outside of the control limits; the associated LCS recovery was acceptable. (This qualifier is for a non -project QC sample.)
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.
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 for but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B -Target analyte detected in the method blank and in the sample at a concentration less than 10x the blank concentration.
• Sulfate MS/MSD % recoveries low for ILFI-LCS-CELL1(M4).
• Sulfate MS % recovery low (MSD ok) for ILF1-LCS-CELL6 (1104).
• The RPD between ILF1-UD1 and the field duplicate is greater than 35%for Iron (0.024/0.004 mg/L).
• Nitrate (0.05 mg/L), Nitrate as N (0.01 mg-N/L), and Boron (0.01 mg/) was detected in the Field Blank; these analytes were not detected in the samples at concentrations less than 10x the
blank concentrations.
• Due to a dilution factor of 2, the Antimony reporting limit (2 ug/L) is greater than the NCAC 02L Groundwater Standard (1 ug/L) and ILF1-LCSC1 was reported as non -detect.
• Per the Duke verification team, the Arsenic result for ILFl-LCSC1 was confirmed by lab.
