Monitoring results in this Report are for the period September 2022 through February 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 the Industrial Landfill No. 1 (landfill). 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 2023 sampling event and this Report comply with the updated 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 debris 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; Cell 5 began operations and started receiving protective cover. 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). Phase 2 of the landfill is divided into two cells (Cell 5 and Cell 6). 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. Page 1 Environmental Controls Monitoring Plan Semiannual Report September 2022 through February 2023 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 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 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 began in October 2021. 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. 1.2 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. Page 2 Environmental Controls Monitoring Plan Semiannual Report September 2022 through February 2023 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 these sources 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-LDS2 MSS-LF-LDS3 MSS-LF-LDS4 MSS-LF-LDS5 LDS identification numbers each correspond to a landfill cell (Cell 1 through Cell 5). 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. 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-LCS4 • MSS-LF-LCS2 • MSS-LF-LCS5 • MSS-LF-LCS3 The identification numbers correspond to the landfill cells (Cell 1 through Cell 5). 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-LCS5 on February 15, 2023. 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. Page 3 Environmental Controls Monitoring Plan Semiannual Report September 2022 through February 2023 Industrial Landfill No. 1 1812-INDUS The leachate samples were measured for the following in situ parameters: • 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 602013; • 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 A discrete underdrain sample was collected from MSS-LF-UD1 location on February 15, 2023. 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 Analytical on August 10, 2022. 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. Constituents were analyzed by Duke Energy Analytical Laboratory. 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. Page 2 Environmental Controls Monitoring Plan Semiannual Report September 2022 through February 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 5) 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 5 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-LDS5 are included in Table 1A through Table 1 E. 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. Cell 2 Cell 5 Rates between December and March are related to a build of sediment and fines at the Cell 2 low flow pump. The buildup caused a decrease in the flow rates of the leachate collection system. The Cell 2 high flow pump was not affected. During this period leachate was primarily pumped using the high -flow pump and it's settings. The Cell 2 low -flow pump was removed for maintenance and cleaning in March 2023. Since the low -flow pump was returned to service after cleaning, the Cell 2 leak detection rates decreased. Rates for April and May 2023 are representative of normal operations and will be included the next semiannual report. Rates during December and January are related to break in period, with high surface area of cell and amount of precipitation received. Page 3 Environmental Controls Monitoring Plan Semiannual Report September 2022 through February 2023 Industrial Landfill No. 1 1812-INDUS 3.2 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-LCS5 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 in 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 any water quality standards. The underdrain field and analytical results for sample MSS-LF-UD1 are included in Table 3. 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. 4.0 References AECOM, November 2020.

If so, then: ❑ ❑ 0 12b) Were any parameters flagged by the lab as being outside the limits of control in the laboratory duplicate sample? ❑� ❑ ❑ 13) Field Duplicate Sample - Is the relative percent difference between the parent and field duplicate sample results greater than 35 percent? ❑ ❑ 14) Field/Equipment/Trip Blanks - Were any parameters detected in the associated field, equipment, and/or trip blanks? ❑ 0 ❑ 14a) If yes, were any target analytes detected in the samples at a concentration less than ten times the Field/Equipment/Mia Blank concentration? ❑v ❑ ❑ 15) Were initial and continuing calibration blank information within acceptable criteria per the lab report? ❑ ❑� ❑ 16) Were any reporting limits for diluted, non -detect results greater than the screening criteria? ❑ ❑ 17) Radionuclides: Are quality control sample results provided? ❑ ❑ ❑� 17a) Are any results flagged or qualified? ❑ ❑ ❑° 17b) Are Uncertainty, MDC, Tracer/ and/or Carrier/ provided for each sample? 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 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. • The RPD between ILF1-LCS-CELL1 and the field duplicate is greater than 35%for Iron (0.033/0.045 mg/L). • Boron (0.029 mg/L) and Cobalt (0.134 ug/L) was detected in the Field Blank; these qualifiers were not detected in the samples at concentrations less than lox the blank concentrations.
