Introduction and Background 1.1 Introduction AECOM Technical Services of North Carolina, Inc. (AECOM)prepared this Annual Infiltration Report on behalf of Duke Energy Carolinas, LLC(Duke Energy) in accordance with the requirements of the Underground Injection Control (UIC) Permit(Permit#W10400551)at the Belews Creek Steam Station (BCSS)located in Stokes County, North Carolina (the Site)(Figure 1).This document provides the monitoring information listed in Part VI of the permit. A general layout of the Site is included in Figure 2. Figure 3 shows the locations of the extraction, infiltration, and performance monitoring wells in the western pilot test area of the Site. The Corrective Action Plan(CAP) Update(SynTerra Corporation [SynTerra], 2019a)and the Demonstration of 02L Compliance for the Belews Creek Ash Basin technical memorandum (Tech Memo)(SynTerra, 2020)presented the proposed remediation strategy to address constituents of interest(COI) in groundwater above the applicable regulatory criteria at or beyond the ash basin Geographic Limitation.The Pilot Test Work Plan(AECOM, 2020) summarized the field-testing plan of the proposed CAP implementation.The CAP strategy includes groundwater extraction and treatment combined with clean-water infiltration for the area northwest of the ash basin. In June of 2020, Duke Energy submitted a UIC permit application for North Carolina Department of Environmental Quality(NCDEQ)approval of the installation and operation of up to 74 clean water infiltration wells.At the request of NCDEQ, additional information was provided in a letter dated August 12, 2020.Approval of UIC permit#WI0400551 was received on October 5, 2020.A permit modification application was submitted to NCDEQ on July 12, 2021, to adjust the reporting requirement and approval of the modification was received on October 7, 2021. The purpose of this Annual Infiltration Report is to summarize the progress of the clean water infiltration system per the UIC permit.The groundwater extraction system was started on August 4, 2021, and clean water infiltration began on November 1, 2021.This report summarizes CAP pilot testing activities from system startup to September 30, 2022. Clean water infiltration will continue as part of the groundwater CAP system and future annual reports will summarize site progress. 1.2 Regulatory Framework Duke Energy has conducted extensive site investigation activities to comprehensively characterize environmental conditions in soil,groundwater, surface water, and sediments associated with the presence of coal combustion residuals(CCR)in and around the BCSS coal ash basin and the Pine Hall Road landfill. Duke Energy performed these activities in compliance with the North Carolina Coal Ash Management Act of 2014, as amended (CAMA), as well as the United States Environmental Protection Agency's(EPA's)CCR Rule. Human health and ecological risk assessments performed at the Site using EPA guidance demonstrate that risks to potential human health and ecological receptors associated with the coal ash basin are not measurably greater than risks posed by naturally occurring background conditions. In 2018,the NCDEQ ranked the ash basin at the BCSS as low-risk pursuant to CAMA.The corrective action discussed in this annual infiltration report is in response to Title 15A North Carolina Administrative Code, Subchapter 02L Groundwater Standard (02L Standard)exceedances beyond the Geographic Limitation shown on Figure 2. Assessment activities identified two contiguous areas located north and northwest of the Geographic Limitation of the ash basin with COI groundwater concentrations above applicable regulatory standards.The Consent Order(CO) signed by Duke Energy on February 5, 2020, specifies obligations related to the closure of coal ash impoundments and groundwater corrective action at six Duke Energy coal combustion sites.The CO defines the BCSS Geographic Limitation of the ash basin as 500 feet from the ash basin waste boundary. Groundwater concentrations greater than applicable 02L Standards, Interim Maximum Allowable Concentrations, or background threshold values(whichever is greater)outside of the ash basin Geographic Limitation must be addressed through corrective action at the Geographic Limitation. AECOM 1 2022 Annual Infiltration Report 60639236 2. Pilot Test The pilot test for the BCSS groundwater CAP was performed in the western treatment area shown in Figure 3.The purpose of the pilot test was to start treatment of the groundwater while providing information to help develop the full-scale infiltration and extraction systems proposed in the CAP.A well construction table summarizing details of the extraction, infiltration and monitoring wells is included as Table 1.The pilot test included 23 groundwater extraction wells and 23 infiltration wells. In addition, 26 performance monitoring wells have been installed to evaluate groundwater quality. Copies of the GW-1 well construction records were included in the Pilot Test Construction Completion Report dated February 2022(AECOM, 2022). Groundwater is being extracted from shallow, deep, and bedrock wells,treated through a modular(Evoqua Water Technologies)treatment system on site and then discharged to permitted outfall 006 as allowed in the National Pollutant Discharge Elimination System permit approved on March 21, 2019.The infiltration water is supplied from nearby Belews Lake.The water is pumped through particulate filtration, metal precipitation, and ultraviolet light treatments and then pumped into the clean water infiltration wells as proposed in the CAP. 2.1 Pilot Test Operation The groundwater extraction system was started on August 4, 2021, and the clean water infiltration began on November 1, 2021. Since startup, clean water infiltration has been conducted at all the infiltration wells.The total volume of clean water infiltrated between November 1, 2021, and September 30, 2022, is approximately 25,599,208 gallons. In addition, approximately 38,528,158 gallons of groundwater have been extracted between August 4, 2021, and September 30, 2022.Appendix A includes the NCDEQ Injection Event Record forms. 2.2 Infiltration Source Water Monitoring In compliance with the UIC permit, a sampling program was initiated to confirm constituents in the source water were below applicable groundwater standards. Samples are collected monthly from a port following the treatment system and prior to infiltration.A table summarizing the current NCDEQ approved sampling program for the clean water infiltration source is included as Table 2. Source water is analyzed monthly for total alkalinity, nitrate, select inorganic ions, select dissolved and total metals, mercury, geochemical parameters and bacterial counts.Additionally, each quarter the source water is analyzed for total polychlorinated biphenyls(PCBs), pesticides, lead and silver,volatile organic compounds (VOCs), semi-volatile organic compounds(SVOCs), and three per-and polyfluorinated substance compounds at the request of NCDEQ. It should be noted that the constituents requested by NCDEQ are unrelated to the Duke Energy operations. A baseline source water sample was collected in April 2021 prior to commissioning the extraction and infiltration well systems. Laboratory analytical results indicated the source water was in compliance with the applicable groundwater standards. Table 3 summarizes the laboratory analytical results between April 2021 and August 2022. Constituent concentrations have been below applicable groundwater standards. 2.3 Groundwater Monitoring Prior to startup of the extraction and infiltration system, a baseline groundwater sampling event was conducted in April 2021. Following startup, quarterly groundwater samples were collected in November 2021, February 2022, and June 2022. Groundwater samples were analyzed for total and dissolved metals, mercury, chloride, sulfate, pH, and total dissolved solids. Laboratory analytical results are summarized on Table 4. AECOM 2 2022 Annual Infiltration Report 60639236 3. Summary and Recommendations A CAP pilot test system was constructed to begin implementation of the proposed corrective action at the Site. Following is a brief summary of site activities: • Pilot test extraction and infiltration wells were installed between September 21 and December 31, 2020. • Groundwater extraction started on August 4, 2021. • Clean water infiltration began on November 1, 2021. • Approximately 25,599,208 gallons of clean water have been infiltrated to enhance groundwater remediation. • Approximately 38,528,158 gallons of groundwater have been extracted since startup. • Quarterly groundwater monitoring has been conducted to monitor remediation progress. • Monthly and quarterly water samples of the clean water source were collected. • Constituents of concern have not been detected in the source water samples above applicable groundwater standards. Based on the source water analytical data collected, Duke Energy recommends modifying the source water monitoring program. Duke Energy requests NCDEQ concurrence for the source water monitoring program proposed below.A reduced sampling program is requested since the constituents analyzed have consistently been below the applicable groundwater standards.
