On December 19-20, 2022, groundwater, surface water, and leachate samples were collected in accordance with the McGuire Landfill No. 2 Sampling and Analysis Plan. The groundwater sampling field and analytical results are summarized in Table 4. The analytical results for the constituents are compared to the groundwater standards found in Title 15A NCAC 02L .0202 (2L Standards). Groundwater results with values that attain or exceed the 2L Standards (or outside of 2L Standard range for pH) are indicated on Table 4 by yellow highlighting. A summary of the groundwater analytical results that attain or exceed the 2L Standards (or outside of 2L Standard range for pH) and a preliminary analysis of the cause and significance of such occurrences are presented in Table 5. In one or more wells, pH measurements were reported outside of the 2L Standard pH range, but no other 2L exceedances were reported for the December 2022 monitoring event. The surface water field and analytical results are summarized in Table 6. The surface water analytical results for the constituents are compared to the surface water standards found in Title 15A NCAC 02B .0211 (213 Standard) for Class C WS IV waters. No 2B Standards were exceeded during the December 2022 monitoring event. The leachate field and analytical results are summarized in Table 7. The leachate sample was collected from the in -flow pipe which conveys leachate from the landfill into the leachate pond. Duke Energy personnel sample designated locations for groundwater, surface water, and leachate at the McGuire Landfill No. 2 (Synthetically Lined) semi-annually during June and December. The next water quality monitoring event for Landfill No. 2 is planned for June 2023 with a report of monitoring results to follow.

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 areas are shown on Figure 1 in Appendix I. 1.2 Hydrologic Setting The 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 located northeast of the landfill drains towards the northwest to an unnamed perennial stream, which discharges into the Catawba River. The Catawba River is classified as a Class C Water Supply -IV water source, (WS-IV). 1.3 Monitoring Program As described in the Sampling and Analysis Plan (SAP) dated May 19, 2022, the current monitoring system at the landfill consists of the following: Monitoring Wells: MW-5R2 MW-8 MW-5A MW-8A MW-6 MW-9 MW-6A MW-9A MW-7R2 MW-10A MW-7A ' In response to the North Carolina Division of Public Health, Radiation Protection Section, November 77, 2006 letter to Duke Energy, LLC, Duke Energy offered to indicate the landfill as synthetically lined in reports. Z Replacement monitoring wells MW-5R and MW-7R were installed on October 70' and 7 lt' 2076 (respectively). The original MW-5 and MW-7 wells did not consistently produce enough water for groundwater sampling. Each of these replacement wells were installed deeper than the original wells, with a 15-foot screened interval, per approval from NCDEQ (Approval Replacement Monitoring Wells MW-5 and MW-7 signed by Elizabeth Werner, Permitting Hydrogeologist, dated July 27, 2076). April 10, 2023 Semi -Annual Water Quality Monitoring Report — December 2022 Sampling Event Duke Energy Carolinas, McGuire, Landfill No. 2 (Synthetically Lined) Permit No. 6004-INDUS S&ME Project No. 22350902, Ph. 03 Surface Water Sample Locations: Leachate Sample Location: SW-1 SW-2 Leachate Pond (in -flow pipe) s 0 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 represent replacement wellsz. As designated in the SAP, monitoring well location MW-5R is upgradient and considered to represent background conditions for the 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 landfill. Well construction information is summarized in Table 1 in Appendix II. Surface water samples are collected from two locations, SW-1 and SW-2, as shown on Figure 2 in Appendix I. Surface water sample location SW-1 is collected from an unnamed perennial stream northeast of the landfill and serves as the background surface water sample location for this monitoring program. Surface water sample location SW-2 is also collected from this unnamed perennial steam, downstream from surface water sample location SW-1 and west of the landfill. The leachate sample is collected from the end of the in -flow pipe, which conveys leachate from the landfill to the synthetically lined leachate collection pond. The leachate pond resumed permanent operational status in February 2021 after the synthetic liner system was replaced at the end of 2020. While the leachate pond was out of service, 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 sample locations, and the leachate pond sample location 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 2022 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 Certification #329), and EnRad Laboratories. Each of the laboratory reports and chain -of -custody forms are included in Appendix IV.

Due to significant DRO hits in the field blanks and elevated results for some well locations, the DRO data package and associated chromatograms were reviewed. The vendor lab determined the DRO results that were not J values should be flagged as possible lab contaminant not present in the method blank. QC Note: The 2-hexanone LCS recovery associated with samples MW-51R, MW-6, MW-6A, MW-7R, MW-7A, and MW-8 exceeded the acceptance criteria. This analyte was not detected in these samples. The acetone, 2-butanone(MEK(, 2-hexanone, and 4 methyl-2 pentanone LCS recoveries associated with samples SW-1, SW-2, and FB-20221220-1145 exceeded acceptance criteria. These analytes were not detected in the samples. 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.

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. Contact your Pace PM for the current list of accredited analytes. TN -The NELAC Institute. ANALYTE QUALIFIERS C7 Analyte is a possible laboratory contaminant (not present in method blank). D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. S2 Surrogate recovery outside laboratory control limits due to matrix interferences (confirmed by similar results from sample re -analysis).
