The landfill is permitted under North Carolina Department of Environmental Quality (NCDEQ) Solid Waste Permit No. 6004-INDUS and currently accepts waste. The landfill was constructed with a high -density polyethylene (HDPE) synthetic liner and leachate collection and removal system. Leachate and contact stormwater are collected in a synthetically lined leachate collection pond and pumped to the McGuire Nuclear Station wastewater treatment system. The landfill and surrounding area are shown on Figure 1 in Appendix I. The approximate limit of waste is shown on Figure 2 in Appendix I. 1.2 Hydrologic Setting The synthetically lined landfill is located south of North Carolina (NC) Highway 73, north of Cashion Road and west of Lindeman Road as shown on Figures 1 and 2 in Appendix I. Cashion Road runs along a surface water divide, with surface flow draining to the northwest and the southeast. A surface water drainage feature is located north of the Synthetically Lined Landfill and drains northwest to an unnamed perennial stream. Surface water sample location SW-1 is collected from this unnamed stream (north of the landfill), upstream of the confluence with the surface water drainage feature. Surface water sample SW-2 is also collected from this unnamed stream, downstream from SW-1 and west of the Synthetically Lined Landfill. The unnamed stream drains west to the Catawba River. The Catawba River is classified as a Water Supply -IV water source (WS-IV). A second surface water drainage feature is located southwest of the Synthetically Lined Landfill and drains northwest to the unnamed stream before discharging to the Catawba River as depicted on Figure 2. 1.3 Monitoring Program As described in the Revised Sampling and Analysis Plan (SAP) dated May 31, 2019, the current monitoring system at the landfill consists of the following: Monitoring Wells: MW-5R MW-8 MW-5A MW-8A MW-6 MW-9 MW-6A MW-9A ' In response to the North Carolina Division of Public Health, Radiation Protection Section, November 17, 2006 letter to Duke Energy, LLC, Duke Energy offered to indicate the landfill as synthetically lined in reports. Z Replacement monitoring wells were installed on October 10 (MW-7R) and 11 (MW-5R), 2016 because the original wells did not consistently produce enough water for sampling. Replacement wells were installed to deeper depths with a 15-foot screened interval, per approval from NCDEQ. See Approval Replacement Monitoring Wells MW-5 and MW-7 signed by Elizabeth Werner, Permitting Hydrogeologist, dated July 27, 2016. February 13, 2023 (Original Report Date April 8, 2022) Semi -Annual Water Quality Monitoring Report (Revision 1) — December 2021 Sampling Event Duke Energy Carolinas, McGuire, Landfill No. 2 (Synthetically Lined) Permit No. 6004-INDUS S&ME Project No. 21350075, Ph. 04 Monitoring Wells (continued): Surface Water Sample Location: Leachate Sample Location MW-7R2 MW-10A MW-7A SW-1 SW-2 Leachate Pond (in -flow pipe) Monitoring wells were installed as well pairs consisting of one shallow well and one deep well (with the exception of monitoring well MW-10A, which does not have an accompanying shallow well). Wells with "A" designations represent the deeper well within each well pair. Wells with "R" designations are replacement wells2. As designated in the SAP, monitoring well location MW-5R is upgradient and considered to represent background conditions for the Synthetically Lined Landfill. Well pair MW-9 and MW-9A were installed adjacent to and downgradient from the leachate pond. The remaining wells were installed adjacent to the Synthetically Lined Landfill. Well construction information is summarized in Table 1 in Appendix II. Surface water sample location SW-1 is collected from the unnamed stream (north of the landfill), upstream of the confluence with the surface water drainage feature that ultimately discharges to the Catawba River. SW-2 is also collected from this unnamed stream downstream from SW-1 and west of the landfill. SW-1 is the designated background sampling location for this monitoring program. The leachate sample is collected from the end of the in -flow pipe, which conveys leachate from the landfill to the leachate collection pond. The leachate pond resumed permanent operational status in February 2021 after the liner system was replaced at the end of 2020. While the leachate pond was out of service during liner replacement activities, leachate was rerouted through a temporary bypass system directly to the McGuire Nuclear Station wastewater treatment system. The locations of the monitoring wells, surface water samples, and the leachate pond sample are shown on Figure 2 in Appendix I. 2.0 Methods 2.1 Sampling and Analysis Methods Groundwater, surface water, and leachate sampling activities were performed by Duke Energy Groundwater Science Group (Duke Energy Carolinas Field Certification #99046001), in general accordance with the North Carolina Solid Waste Management Guidelines. Copies of the December 2021 field sampling forms are included in Appendix III. The parameters and constituents reported were selected in accordance with the SAP and the NCDEQ Division of Waste Management, Solid Waste Section and were analyzed by the Duke Energy Analytical Laboratory (North Carolina Laboratory Certification #248), Pace Analytical Services (North Carolina Laboratory February 13, 2023 (Original Report Date April 8, 2022) Semi -Annual Water Quality Monitoring Report (Revision 1) — December 2021 Sampling Event Duke Energy Carolinas, McGuire, Landfill No. 2 �r (Synthetically Lined) Permit No. 6004-INDUS S&ME Project No. 21350075, Ph. 04 Certification #329), and EnRad Laboratories. The laboratory reports and chain -of -custody forms are included in Appendix IV. 2.1.1 Groundwater, Surface Water, and Leachate The groundwater, surface water, and leachate samples were analyzed for the following parameters using the following analytical methods in accordance with the SAP: • Barium, calcium, magnesium, potassium, and sodium using Solid Waste (SW)-846 Method 6010D • Arsenic, cadmium, chromium, lead, selenium, and silver using SW-846 Method 6020B • Mercury using SW-846 Method 7470A • Sulfate and Chloride using SW-846 Method 9056A • TPH Diesel Range Organics (TPH-DRO) using SW-846 Method 8015C Modified with 3520C sample preparation • 1,4-Dioxane using SW-846 Method 8260B (SIM) with 5030B sample preparation. • Alkalinity using Method SM2320B • Volatile organic compounds (VOCs) using SW-846 Method 8260 The surface water sample was also field -filtered using a 0.45-micron in -line filter and dissolved analyses were performed for the following constituents: • Barium using SW-846 Method 6010D • Arsenic, cadmium, chromium, lead, and silver using SW-846 Method 6020B 2.1.2 Radiological Samples In accordance with the requirements of the Radioactive Materials License No. 060-0379-7 issued by the North Carolina Department of Health and Human Services Radiation Protection Section, the following radiological analyses were performed on groundwater and surface water samples: • Gross alpha and beta radioactivity using EPA Method 900 • Tritium using EPA Method 906.0 Modified • Gamma radioactivity for select isotopes 2.2 Statement of Work S&ME completed the following tasks: February 13, 2023 (Original Report Date April 8, 2022) 3 Semi -Annual Water Quality Monitoring Report (Revision 1) — December 2021 Sampling Event Duke Energy Carolinas, McGuire, Landfill No. 2 �r (Synthetically Lined) Permit No. 6004-INDUS S&ME Project No. 21350075, Ph. 04 Received field sampling data from Duke Energy (performed by Duke Energy Groundwater Sciences Group) for monitoring wells MW-5R, MW-5A, MW-6, MW-6A, MW-7R, MW-7A, MW-8, MW-8A, MW-9, MW-9A, MW-10A. Data was also received for surface water sample location SW-1 and SW-2 and the leachate pond. The samples were collected between December 131" and 141", 2021, and S&ME received the data from Duke Energy via e-mail correspondence from Courtney Murphy (Duke Energy) to Julie Robertson and Jasmine Tayouga (S&ME) on February 811, 2022. • Reviewed the laboratory analytical results and the Electronic Data Deliverables (EDDs) provided by Duke Energy for the samples noted above. • Developed a shallow groundwater contour map and calculated groundwater flow velocities using survey data and groundwater levels measured by Duke Energy Groundwater Sciences Group. 3.0 Results 3.1 Site Groundwater Flow Shallow groundwater surface contours and groundwater flow direction in the vicinity of the landfill are shown on Figure 3 in Appendix I. These contours were developed using the depth to groundwater measurements in the shallow wells on the date of sampling and top of well casing elevations. Calculated groundwater flow velocities are presented on Table 2 in Appendix II. Based on groundwater elevations calculated for the December 2021 sampling event, groundwater flow is generally from the southeast to the north and northwest toward the Catawba River. 3.2 Analytical Results 3.2.1 Groundwater Laboratory results for groundwater samples were compared to the Title 15A NCAC Subchapter 2L Standards (2L Standards) to evaluate compliance with NCDEQ groundwater quality standards. In one or more wells, pH measurements were reported outside of the 2L Standard pH range. No other exceedances of 2L Standards were reported for groundwater samples collected during the December 2021 sampling event. A summary of field data parameters recorded prior to sample collection is presented in Table 3 in Appendix II. A summary of groundwater analytical results for the current sampling event is presented in Table 4 in Appendix II. A summary of the groundwater analytical results that equal or exceed the 2L Standards and a comparison to historical concentration ranges are presented in Table 5 in Appendix II. 3.2.2 Surface Water Laboratory results for the surface water samples (SW-1 and SW-2) were compared to the Title 15A NCAC Subchapter 213 Standards (213 Standards) for Class WS-IV waters to evaluate compliance with established criteria. February 13, 2023 (Original Report Date April 8, 2022) 4 Semi -Annual Water Quality Monitoring Report (Revision 1) — December 2021 Sampling Event Duke Energy Carolinas, McGuire, Landfill No. 2 (Synthetically Lined) Permit No. 6004-INDUS S&ME Project No. 21350075, Ph. 04 No constituents exceeded 2B Standards in the surface water samples collected during the December 2021 sampling event. A summary of field data parameters recorded prior to sample collection is presented in Table 3 in Appendix II. A summary of surface water analytical results for the December 2021 sampling event is presented in Table 6 in Appendix II. 3.2.3 Leachate The leachate sample was collected from the in -flow pipe which conveys leachate from the landfill into the leachate pond. A summary of field data parameters recorded at the time of sample collection is presented in Table 3 in Appendix II. A summary of analytical results for the current sampling event is presented in Table 7 in Appendix II. 3.2.4 Radiological Samples The results of the radiological analyses are presented in Table 8 in Appendix II. A copy of the laboratory report has been submitted to the North Carolina Department of Health and Human Services Radiation Protection Section for reference and is also included in this report in Appendix IV. S&ME did not evaluate this data. 3.2.5 Quality Assurance / Quality Control Field -performed quality assurance and quality control (QA/QC) consisted of the collection and analysis of two field blanks (one on each day of sampling) to evaluate if contamination was imparted to the samples by the sample container, preservative, or other exogenous sources. Samples for the monitoring wells and surface water were submitted to Duke Energy Analytical Laboratories on December 17. Bromomethane and vinyl chloride laboratory control sample (LCS) recovery was above acceptable limits, however the associated samples were non -detect for these samples, indicating that data quality was not impacted. MW-5R, MW-5A, MW-6A, and MW-8 analysis initially suggested tetra chloroethene carry over. Samples were then reanalyzed outside of the analytical holding time. Reanalyzed samples were non -detect. Two Trip Blanks were transported with the VOC samples to evaluate the effects of shipping and laboratory sources of contamination. These samples were received by the laboratory and analyzed outside of the method holding time. All constituents were non -detect. 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 reported in the lab report. Additional QA/QC data, laboratory analyses, and chain -of -custody forms are included in Appendix IV.

QC Notes 1/14/2022 Bromomethane laboratory control sample (LCS) recovery was outside of the acceptance limits. The associated samples MW- 7R, MW-7A, MW-9, MW-9A, SW-1, and SW-2 were non -detect for this compound. Data quality was not impacted. Bromomethane and vinyl chloride LCS recoveries were above the acceptance limits. The associated samples FB-20211214- 0930 and TB-20211130-0745 were non -detect for these compounds. Data quality was not impacted. MW-5R, MW-5A, MW-6, MW-6A and MW-8 were reanalyzed outside of the analytical holding time; the initial analysis performed within holding time had suspected tetrachloroethene carry over. All reanalyzed samples were non -detect. The trip blank was received and analyzed outside of the method holding time. All associated compounds were non -detect.

If you have any questions regarding this report please contact the Pace Project Manager listed on the cover page. This report supersedes and replaces any prior reports issued under this lot number. Samples -017 and - 018 clients IDS were updated to match chain of custody. Sample -013 collection time was revised per client request. Volatiles The method blank associated with batch 26831 had toluene detected at a concentration that was below'/z the LOQ. All samples associated with this method blank that have detections for toluene have been flagged with a "B" qualifier. The laboratory control sample (LCS) associated with batch 26831 had bromomethane recovered marginally outside of the acceptance limits. This could potentially result in a high bias on analytical results. There were no detections for this compound in the samples associated with this batch; therefore, data quality is not impacted. The laboratory control sample (LCS) associated with batch 26885 had bromomethane and vinyl chloride recovered above the acceptance limits. This could potentially result in a high bias on analytical results. There were no detections for this compound in the samples associated with this batch; therefore, data quality is not impacted. Samples -001, -002, -003, -004 and -007 were reanalyzed performed outside of the analytical holding time. The initial analysis had suspected tetrachloroethene carry over. Sample -017 was received outside of holding time.
