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 14, 2022, leachate samples were collected from the leachate collection system from Cells 1, 2, 3
and 4 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 2022 with documentation to follow.

Environmental Controls Monitoring Plan Semiannual Report September 2021 through February 2022
Industrial Landfill No. 1 1812-INDUS
1.0 Background
This Environmental Controls Monitoring Plan Semiannual Report (Report) is for the Industrial Landfill
No. 1 — Phase 1 (Cells 1 through 4) and Phase 2 (Cell 5 underdrain) (1812-INDUS) located at the Duke
Energy Carolinas (Duke Energy) Marshall Steam Station (Marshall/Plant/Site). Monitoring results in this
Report are for the period September 2021 through February 2022.
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 the
Industrial Landfill No. 1 (landfill). In 2021, the ECMP, Revision 1 (SynTerra, 2020b) was revised to
incorporate a landfill underdrain sample location and the leachate basin leak detection monitoring
location. The ECMP, Revision 2 (SynTerra, 2021) was submitted to the North Carolina Department of
Environmental Quality (NCDEQ) Division of Waste Management (Division) on December 13, 2021 and
approved by the Division on December 14, 2021. An updated ECMP, Revision 2 was provided to the
Division on January 11, 2022; the updated ECMP, Revision 2 was related to correction of errors in
Table 1 — Summary of Constituents and Analytical Methods. The Division acknowledged and replaced
the December 14, 2021, approved ECMP, Revision 2 (SynTerra, 2021) with the updated January 11,
2022 ECMP, Revision 2 (SynTerra, 2022). The February 2022 sampling event and this Report comply
with the ECMP, Revision 2 (SynTerra, 2022).
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 Title 15A Subchapter 13B (NCAC 15A
13B) .0504(c)(8)(D) in accordance with NCGS 130A §295.4(c).
1.1 Site Description
Refer to the ECMP Section 1.1 for additional site description information.
1.1.1 Landfill
The approximate 67.1-acre landfill (Phase 1 and 2) acre landfill 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)
landfill areas (1804-INDUS) to the east, and the Structural Fill (CCB0031), industrial
stormwater pond (MAR-145), 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.
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 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). Each
cell has a discrete low area (sump) where leachate is collected for removal from the
landfill by mechanical pumping and the LDS is monitored. Phase 2 of the landfill is
proposed to be divided into two cells (Cell 5 and Cell 6).

Environmental Controls Monitoring Plan Semiannual Report September 2021 through February 2022
Industrial Landfill No. 1 1812-INDUS
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.
1.1.2 Leachate Basin
There is no landfill leachate basin in operation at Marshall. However, a leachate basin is
currently under construction with the Industrial Landfill No. 1, Phase 2 expansion
construction.
Until construction is complete of the leachate basin, leachate continues to be conveyed
from the landfill to the Lined Retention Basin (LRB) where it is comingled 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 constructed without 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 portions of Cell
5 of Phase 2. The underdrain is composed of a two -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 started
in October 2021. The underdrain has been in operations since this time, while
construction of Cell 5 continues.
1.1.4 Surface Water
Landfill area stormwater is directed via channels around the perimeter of the landfill to a
NPDES permitted wastewater unit or NPDES permitted outfall.
1.21 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.

Environmental Controls Monitoring Plan Semiannual Report September 2021 through February 2022
Industrial Landfill No. 1 1812-INDUS
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, as
sources that have historically been used to store or dispose the predominant material in the
landfill (CCR).
Refer to the ECMP Section 1.2 for additional site geology and hydrology information.
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 sump identified as:
MSS-LF-LDS1 MSS-LF-LDS3
MSS-LF-LDS2 MSS-LF-LDS4
LDS identification numbers each correspond to a landfill cell (Cell 1 through Cell 4). 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. LDS pump totalizer (flow meter) are recorded.
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-LCS2 MSS-LF-LCS4
The identification numbers correspond to the landfill cells (Cell 1 through Cell 4). 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-LCS4 on February 14, 2022. The collection of samples and documentation of
sampling was performed by PACE Analytical personnel (North Carolina Field Certification
#5342) 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.
The leachate samples were measured for the following in situ parameters:

Environmental Controls Monitoring Plan Semiannual Report September 2021 through February 2022
Industrial Landfill No. 1 1812-INDUS
• pH, specific conductivity, temperature, dissolved oxygen, oxidation reduction potential
using a water quality meter; and
• Turbidity using a turbidity meter.
The leachate samples were analyzed for the following constituents:
• Barium, boron, calcium, iron, lithium, magnesium, manganese, and zinc using United
States Environmental Protection Agency (USEPA) Method 601 OD;
• Antimony, arsenic, beryllium, cadmium, chromium, cobalt, copper, lead, molybdenum,
nickel, selenium, thallium, and vanadium using USEPA Method 6020B;
• Chloride, fluoride, nitrate (as nitrogen), and sulfate using USEPA Method 9056A;
• Mercury using USEPA Method 7470A;
• Silver using USEPA Method 6020A; and
• Total dissolved solids using Standard Method (SM) 2540C.
Leachate field parameters and analytical results are summarized in Section 3.0.
2.3 Underdrain Outlet Sampling and Analysis
An underdrain sample collected in the vicinity of the landfill sump from the underdrain
discharge is identified as MSS-LF-UD1. Due to ongoing construction associated with Phase 2
of the landfill, a temporary, alternative downstream location was sampled during the February
2022 sampling event with NCDEQ's concurrence. The general location of the underdrain
monitoring location and February 2022 temporary, alternative downstream monitoring location
(identified as MSS-LF-UD1*) are shown on Drawing 2.
A discrete underdrain sample was collected from the alternative downstream location on
February 14, 2022. The sample collection and documentation were performed by PACE
Analytical personnel in accordance with procedures provided in Duke Energy's Landfill Sample
Collection Guideline (ECMP Appendix 1). In addition to the routine sampling documentation, a
photo of the sampling location and GPS coordinates were collected by PACE on February 14,
2022.
Copies of the field calibration, sampling form, sampling photo, and GIPS coordinates 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. The laboratory report and chain -of -custody (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 and those 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 September 2021 through February 2022
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 4) and compared to the IRLR and ALR for the landfill LDS as defined in the
Operations Plan.
Average daily leakage rates for Cell 1 through Cell 4 were calculated as follows:
1. Calculate the monthly total volume pumped (gallons):
monthly volume pumped (gallons) = currentmonth total flowmeterreading — preceding
month total flow meter reading
2. Calculate the average daily leakage rate [gallons per acre per day (gpad)]:
average dailyleakage 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-LDS4 are included in
Table 1A through Table 1 D. The LDS leakage rate data collection details are kept with onsite
records.
Below are note(s) for variances in data (e.g., total volume pumped) and explanations for any
leakage rates outside of the normal range for the Cell.
The Cell 2 average daily leakage rate for December 2021, January 2022, and February
2022 were calculated as 13.6 gpad, 1.0 gpad, and 13.5 gpad, respectively. The higher
leakage rates recorded in December and January is related to issues with the flow
meter. Since December 2021, the pump hour meter indicated 5.6 hours of run time
(Table 1B). Because the total number of hours of pumping did not change between
December 2021 and February 2022, this suggests that no pumping occurred, and the
total flow and calculated leakage rates are a function of issues with the flow meter.
3.21 Leachate Field and Analytical Results
Leachate analytical results are not compared to any water quality standards.
The leachate field and analytical results for samples MSS-LF-LCS1 through MSS-LF-LCS4
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 electronic data deliverable (EDD) and in the laboratory
analytical report. The laboratory analytical report, data validation checklist, and chain-of-

Environmental Controls Monitoring Plan Semiannual Report September 2021 through February 2022
Industrial Landfill No. 1 1812-INDUS
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 any water quality standards.
The underdrain field and analytical results for sample MSS-LF-UD1 are included in Table 2.
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.

J Analyte detected above the MDL, but below the RL. Analyte concentration should be considered an estimate.
N1 See Case Narrative for additional information.
N1: ILF1-LCS-CELL 2 alkalinity sample contained a large amount of sediment. When the sample was shaken to
obtain a homogenous mixture per the method, the pH of the sample prevented an alkalinity reading to be obtained.
In order to analyze the sample, it was allowed to stand with the sediment settling to the bottom of the sample
container. A portion of the top layer was used for the analysis.
