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 encompasses 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 March 2023 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 2024 Page 1-2 Project: 00.0083.61 Semiannual Water Quality Monitoring Report — September 2023 Sampling Event Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS) Terrell, North Carolina 2.0 METHODS 2.1 Sampling and Analysis Methods Duke Energy Groundwater Science Group personnel (Duke Energy North Carolina Field Certification #5193) performed groundwater sampling on September 11, 2023, 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. Duke Energy developed a list of parameters and constituents using guidance from the NCDEQ DWM, Solid Waste Section (SWS). The samples were analyzed using the updated parameter and constituent list, approved by NCDEQ on March 20, 2023. 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 1SA, NCAC, Subchapter 02B .0200, Surface Water and Wetland Standards (0213) 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, surface water, and leachate samples on September 11, 2023. • 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 2024 Page 2-1 Project: 00.0083.61 Semiannual Water Quality Monitoring Report — September 2023 Sampling Event Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS) Terrell, North Carolina 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 shallow flow zone. Those contours were developed by calculating groundwater elevations in each monitoring well using the depth -to - water measurements taken during the September 2023 monitoring event. 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 September 2023 water -level sweep 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 8. 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 standards. Constituent concentrations equal to or greater than 02L standards are noted in Table 6 in bold font. The laboratory analytical reports are included in 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. The concentrations and historical range are demonstrated in Appendix C. Surface Water The sample location, SW-1, is shown on Figure 2. Surface water was not sampled during the reporting period because SW-1 was dry. Analytical results for the surface water sample, when available, are compared with applicable 02B Class C and WS-IV surface water standards.
