The North Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management (DWM) issued a permit to operate (PTO) the FGD Residue Landfill (Landfill; No. 1809 - INDUS) on November 21, 2006. Closure activities began in July 2018 and were completed in March 2019; the Closure Permit was issued on June 30, 2020. The Landfill consists of an 18- acre landfill footprint. The FGD Residue Landfill is constructed with a leachate collection and removal system and an engineered liner system to prevent effects on groundwater. 1.2 Hydrogeologic Setting The Landfill site is located within the Piedmont physiographic province (Piedmont). Piedmont bedrock primarily consists of igneous and metamorphic bedrock. The fractured bedrock is overlain by a mantle of unconsolidated material known as regolith. The regolith includes, where present, the soil zone, a zone of weathered, decomposed bedrock known as saprolite, and alluvium. Saprolite, the product of chemical and mechanical weathering of the underlying bedrock, is typically composed of clay and coarser granular material up to boulder size and may reflect the texture of the rock from which it was formed. The weathering product of granitic rocks may be quartz -rich and sandy -textured, whereas rocks poor in quartz and rich in feldspar and other soluble minerals form a more clayey saprolite. Groundwater at the Site typically occurs in three interconnected flow zones. The shallowest groundwater flow zone — the surficial flow zone — occurs in the residual soil and/or the upper section of saprolite. Beneath the surficial flow zone, the transition zone flow zone occurs in the lower portions of the saprolite and partially weathered bedrock and is the most permeable part of the Site hydrogeologic system. Bedrock underlies the transition zone and comprises the least permeable flow zone of the Site hydrogeologic system, where groundwater flow occurs predominantly along fractures, joints, and faults. Groundwater is usually first encountered in the surficial flow zone. Groundwater flows to the south and emerges in a discharge zone. The water flows from the discharge zone to an unnamed tributary that ultimately flows to Lake Norman. The surface water classification of Lake Norman is WS-IV.

The September 2022 sampling event and this Semiannual Water Quality Monitoring Report comply with WQMP, Revision 2 (Wood, 2019) submitted to the DWM on July 24, 2019. The Landfill semiannual monitoring program, described in detail in the WQMP, consists of nine groundwater monitoring locations, one surface water monitoring location, and one leachate monitoring location (Table 3 and Figure 2). A summary of monitoring well construction information is presented in Table 1, and analytical parameter coverage for the Landfill semiannual water quality monitoring program is summarized in Table 2. January 2023 Page 1-2 Project: 00.0083.55 Semiannual Water Quality Monitoring Report — September 2022 Sampling Event Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS) Terrell, North Carolina 2.0 METHODS 2.1 Sampling and Analysis Methods Groundwater sampling was performed by Duke Energy Groundwater Science Group personnel (Duke Energy North Carolina Field Certification #5193) on September 28, 2022, in accordance with the North Carolina Solid Waste Management Guidelines. Copies of the field sampling forms are included in Appendix A. Duke Energy Analytical Laboratory (North Carolina Laboratory Certification #248) analyzed the samples for reported parameters and constituents. The laboratory report and chain -of -custody forms are included in Appendix B. The samples were analyzed for the list of parameters and constituents outlined in the WQMP and guidance from the NCDEQ DWM, Solid Waste Section (SWS). The monitoring parameters, along with the U.S. Environmental Protection Agency (USEPA) Solid Waste (SW)-846 analytical methods, Title 15A, North Carolina Administrative Code (NCAC), Subchapter 02L .0202(g) Groundwater Quality Standards (02L), and Title 15A, NCAC, Subchapter 02B .0200, Surface Water and Wetland Standards (02B) are presented in Table 2. 2.2 Regulatory Criteria Semiannual monitoring analytical results were compared to the following regulatory criteria: Grnundwater • 02L standard Surface Water • 02B standard 2.3 Statement of Work The following tasks were completed for semiannual water quality monitoring: • Collected groundwater and leachate samples on September 28, 2022. A surface water sample was not able to be collected because of dry conditions. • Reviewed the laboratory analytical results pertaining to the parameters listed in Table 2. • Compared groundwater analytical results to the 02L standard and historical concentration ranges. • Developed generalized groundwater surface contour maps using groundwater elevation data. • Calculated groundwater flow velocities based on groundwater elevations at wells perpendicular to groundwater flow. • Converted the laboratory -provided electronic data deliverable (EDD) to the format requirements of the NCDEQ DWM EDD template and submitted copies of the EDDs to the NCDEQ DWM with this report. • Prepared and submitted this Semiannual Water Quality Monitoring Report. January 2023 Page 2-1 Project: 00.0083.55 Semiannual Water Quality Monitoring Report — September 2022 Sampling Event Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS) Terrell, North Carolina 3.0 RESULTS 3.1 Site Groundwater Flow Groundwater flow in the aquifer beneath the Landfill footprint generally flows to the east and southeast beneath the landfill, toward the Ash Basin and Lake Norman. Generalized groundwater elevation contours and groundwater flow direction arrows in the vicinity of the Landfill are shown on Figure 3 for the surficial flow zone. These contours were developed by calculating groundwater elevations in each monitoring well using the depth -to - water measurements taken during the September 2022 monitoring event. In addition, water - level measurements from nearby groundwater monitoring wells included in other Site groundwater monitoring programs were used. Depth -to -water measurements and calculated groundwater elevations are presented in Table 1. Calculated groundwater flow velocities are presented in Table 4. Calculated groundwater elevations based on depth -to -water measurements gauged during the Fall 2022 water level sweep (August 8, 2022) indicate groundwater at the Landfill generally flows to the east-southeast, consistent with historical Site observations. 3.2 Analytical Results Analytical results and reference comparisons discussed below are summarized in Table 5 through Table 9. Sample locations are depicted on Figure 2. Leachate A leachate sample was collected from C-1 on the east side of the Landfill. Analytical results are presented in Table S. Leachate analytical results are not compared to groundwater (02L) or surface water (02B) quality standards and are provided for informational purposes only. Groundwater Results Field and analytical results for the collected downgradient and background groundwater samples are presented in Table 6. Groundwater analytical results are compared with 02L standard. Constituent concentrations equal to or greater than their 02L standard are noted in Table 6 in bold font. The laboratory analytical reports are included as Appendix B. A summary of the downgradient groundwater field and analytical results that are equal to or greater than applicable comparison criteria is presented in Table 7. Constituent concentrations greater than their applicable comparative criteria are within the historical range except pH at MS-10 and MS- 12. The pH values at MS-10 and MS-12 are greater than the historical range. Surface Water The surface water sample location was dry on September 28, 2022, therefore no sample was collected. The sample location is shown on Figure 2.

A field duplicate sample was also collected to estimate sampling and laboratory precision. Select samples were diluted, as is normal laboratory practice, to bring samples within the calibrated range of the analysis. Specifics regarding the samples that were diluted, including the dilution amount, are in the lab report in Appendix B. Additional QA/QC data, laboratory analyses, and chain -of -custody forms are included in Appendix B.

Suite 100 Huntersville, NC 28078 (704)875-9092 QUALIFIERS Project: J22070248 MSS LF Pace Project No.: 92620222 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

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 (Duke) -Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate. 7 U (Duke) -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. • MW-1 not collected due to dry well. • Calcium (0.014 mg/L) was detected in the Equipment Blank; Calcium was not detected in the samples at concentrations less than lox the blank concentration. • Nitrate (0.03 mg/L) and Nitrate as N (0.01 mg-N/L) were detected in the Field Blank; Nitrate and Nitrate as N were not detected in the samples at concentrations less than 10x the blank concentrations.

Due to significant figure limitations to the test code for nitrate as N, the equipment blank result was reported as 0 J. The actual result has been manually entered. QC Note: A constant weight (method requirement) could not be achieved for TDS sample MS-15. Data Flags & Calculations: 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. The qualifier description is found at the end of the Certificate of Analysis (sample results) under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the subcontracted lab final report.

Suite 100 Huntersville, NC 28078 (704)875-9092 QUALIFIERS Project: J22080352 MSS LF Pace Project No.: 92628383 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

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. J (Duke) -Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate. U (Duke) -Analyte was analyzed for, but not detected above the MDL. 7 lg (Pace) - Constant weight could not be achieved for this sample after 4 drying cycles. The final weight change was 0.0018 g. 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 lox the blank concentration. • Achieving constant weight for TDS sample MS-15 was not possible, result should be considered an estimate (lg). • Mercury (0.024 ug/L) was detected in several Method Blanks; Mercury was also detected in the samples at concentrations less than lox the blank concentrations. • The RPD between MS-9 and the field duplicate is greater than 35% for Nitrate (0.88/2.8 mg/L) and Nitrate as N (0.20/0.63 mg/L). • Per Duke Lab, the test code is set up to report Nitrate as N with two significant figures; the actual result for the Equipment Blank is 0.004 J mg-N/L. • Nitrate as N (0.004 mg-N/L), Mercury (0.01 ug/L), Calcium (0.033 mg/L), and Iron (0.005 mg/L) were detected in the Equipment Blank; Nitrate as N, Mercury, Calcium, and Iron were also detected in the samples at concentrations less than lox the blank concentrations. • Mercury (0.01 ug/L), Boron (0.005 mg/L), and Chromium (0.38 ug/L) were detected in the Field Blank; Mercury, Boron, and Chromium were also detected in the samples at concentrations less than lox the blank concentrations. • Revised report issued 10/31/2022. Due to significant figure limitations to the test code for Nitrate as N, the equipment blank result was reported as 01 The actual result has been manually entered.
