The station is owned and operated by Duke Energy Progress (Duke Energy). The North Carolina Department of Environmental Quality (NCDEQ, formally NCDENR) issued a permit to operate (PTO) an on-site landfill (Permit #7305) on July 10, 2014. Phase 1 of the landfill consists of 31 acres out of a possible total 104-acre proposed landfill footprint. The capacity of Phase 1 is 1,592,000 cubic yards. The landfill was constructed with a double high-density polyethylene liner with leak detection, groundwater monitoring, and leachate collection systems. As described in the Water Quality Monitoring Plan (WQMP; Golder, 2014), the landfill is located within the Piedmont physiographic province. The Piedmont physiographic province is comprised of several geologic belts with areas of similar rock types and geologic history. The landfill is located within the Milton Belt which includes metamorphosed volcanic and sedimentary rocks. According to the WQMP, during the field investigation for the landfill Design Hydrogeologic Report, three hydrogeologic units were identified on site: saprolite, partially weathered rock (PWR), and bedrock. Groundwater was generally not encountered in the saprolite unit. Groundwater was encountered in the PWR unit over much of the landfill site. The bedrock hydrogeologic unit is continuous across the landfill site. The landfill site is located on an upland area with surface water drainage features that discharge to the east and northeast into Bowe's Branch, a tributary of the Hyco River. The surface water features to the west of the landfill site drain to the northwest to an un-named tributary of Bowe's Branch. The landfill location and nearby area are presented on Figure 1. Figure 2 shows the Phase 1 landfill site, topography, and vicinity features. As described in the WQMP, the monitoring system for the Phase 1 portion of the landfill consists of the following: Monitoring Wells: LMW-1 LMW-2 LMW-3 LMW-4 LMW-5 Mayo Semiannual Groundwater Monitoring Report – April 2017 Sampling Event June 2017 Duke Energy Progress SynTerra Page 2 P:\Duke Energy Progress.1026\05.MAYO\2017 Well Sampling Monofill\April 2017 Solid Waste\April 2017 Mayo Landfill Report_1.docx Surface Water Sample Locations: SW-1 SW-2 SW-3 Leachate Sample Locations: L-1 L-2 Historically, these monitoring wells have been named, MW-1, MW-2, MW-3, MW-4, and MW-5. There are separate wells located around the Mayo Plant Ash Basin that are also named MW-2, MW-3, and MW-4, which are often sampled in the same sampling event as the landfill monitoring wells. To avoid confusion, beginning in November 2016, the landfill monitoring wells have been renamed, LMW-1, LMW-2, LMW-3, LMW-4, and LMW-5 to distinguish them from those around the Ash Basin. Landfill monitoring wells, surface water sampling locations, and leachate sampling location L-1 are depicted on Figure 2. According to the WQMP, LMW-1 serves as a background water quality monitoring well and is located upgradient of the landfill. The WQMP states the monitoring network is designed to monitor for releases to the uppermost aquifer at the landfill. The wells were installed with screen lengths ranging from 10 feet to 20 feet in length. Table 1 presents well construction information for the landfill monitoring wells. Surface water sampling location SW-1 is located on an un-named perennial stream (tributary of Bowes Branch) and is southwest of Phase 1. SW-1 is located upstream of where groundwater from the Phase 1 area would discharge into the un-named stream or Bowes Branch. Surface water sampling location SW-2 is located on Bowes Branch to the east of the Phase 1 landfill. Surface water sampling location SW-3 is located on Bowes Branch downstream from SW-1 and SW-2. The surface water flow direction as indicated on Figure 2 is generally from the south to the north. Leachate sample L-1 is collected from the facility's leachate tanks located to the west of the Phase 1 landfill. The leachate sample is collected from an in-line sampling valve linked to each of the three leachate tanks; therefore, the sample is considered a composite leachate sample. The facility has the ability to direct leachate through a force main to the National Pollutant Discharge Elimination System (NPDES) permitted scrubber blowdown pond located on the east side of NC Highway 501. Should the facility have no leachate in the leachate tank system and be diverting leachate from the landfill to the scrubber blowdown pond, the leachate sample will be collected from the end of the pipe at the scrubber blowdown pond. If the leachate sample is collected from this location, it will be identified as L-2.

Copies of the field sampling forms are included in Appendix A. The parameters and constituents reported were selected by Duke Energy and the NCDEQ Division of Solid Waste and were analyzed by Duke Energy Analytical Laboratory (North Carolina Laboratory Certification #248). The laboratory report and chain-of-custody forms are included in Appendix B. The groundwater and surface water samples were analyzed for the following constituents: Barium, boron, chromium, copper, iron, manganese, nickel, silver, and zinc using U.S. Environmental Protection Agency (EPA) Method 200.7 Arsenic, cadmium, lead, and selenium using EPA Method 200.8 Chloride, fluoride, nitrate (as nitrogen), and sulfate using EPA Method 300.0 Mercury using EPA Method 245.1 Total dissolved solids using Standard Method (SM) 2540C Surface water samples were analyzed for the constituents listed above and the following additional dissolved constituents: Cadmium, chromium III, copper, lead, nickel, silver, and zinc using EPA Method 200.8 Chromium VI using EPA Method 218.6 Total organic carbon, biochemical oxygen demand, chemical oxygen demand, and dissolved metal constituents were historically sampled. These constituents are not currently required to be analyzed in the WQMP and were not analyzed for during this sampling event.

Received April 2017 field sampling information (compiled by Duke Energy and redistributed to SynTerra) for monitoring wells LMW-1, LMW-2, LMW-3, LMW-4, and LMW-5. Data also included surface water sample locations SW- 1, SW-2, and SW-3, and leachate sample L-1. The samples were collected on April 5, 2017. The field and analytical data were received on May 3, 2017. Reviewed the laboratory analytical results for the samples listed above. The Electronic Data Deliverable (EDD) provided by Duke Energy was adapted to conform to the format requirements of the NCDEQ EDD template. A copy of the original EDD is retained in SynTerra's files. Developed generalized groundwater surface contour map using map data and groundwater elevation data. Calculated groundwater flow velocities are based on groundwater surface contours. Prepared and submitted this Semiannual Groundwater Monitoring Report to Duke Energy. Mayo Semiannual Groundwater Monitoring Report – April 2017 Sampling Event June 2017 Duke Energy Progress SynTerra Page 5 P:\Duke Energy Progress.1026\05.MAYO\2017 Well Sampling Monofill\April 2017 Solid Waste\April 2017 Mayo Landfill Report_1.docx 3.0 RESULTS 3.1 Site Groundwater Flow Generalized groundwater surface contours and indicator of groundwater flow direction for the site are shown on Figure 3. Contours were developed using the groundwater elevations measured on the date of sampling. Calculated flow velocities are presented in Table 2. Groundwater flow in the aquifer beneath the Phase 1 footprint is from the areas of higher topography located along the central and western portion of the Phase 1 footprint generally towards the reach of Bowes Branch located along the eastern boundary of the landfill. 3.2 Analytical Results A summary of the field sample collection data is presented in Table 3. The field and analytical results of groundwater samples collected from the monitoring wells are presented in Table 4. The analytical results for these samples are compared to the groundwater standards established in Title 15A NCAC 02L .0202 (g) (2L Standards). Concentrations that attain or exceed the 2L Standards are noted in Table 4 by bold font. A summary of the field and analytical results that attain or exceed the 2L Standards and a preliminary analysis of the cause and significance of the exceedances are presented in Table 5. Surface water sample location SW-1 is located on an un-named perennial stream (tributary of Bowes Branch) and surface water sampling locations SW-2 and SW-3 are located on Bowes Branch. Bowes Branch is classified by the NCDEQ Division of Water Quality as a Class C water body. As a result, the field and analytical results from these locations are compared to Title 15A NCAC Subchapter 2B Standards (2B Standards) for Class C waters. The field and analytical results for the surface water samples are summarized in Table 6. Concentrations with values that attain or exceed the 2B Standards are noted in Table 6 by bold font. A summary of the field and analytical results that equal or exceed the 2B Standards and a preliminary analysis of the cause and significance of the exceedances are presented in Table 7. The field and analytical results for leachate sampling are summarized in Table 8.

Holding time was reduced to 24hours therefore results have been flagged out of hold. Anions: Please note that the internal standard recovery was below method limits for sulfate likely due to method interference (leachate). Respective batch quality is acceptable therefore data is valid. 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.
