OPERATING REPORT January 1, 2020 through December 31, 2020 Renewed Facility Operating License No. NPF-63 Appendix B Docket No. 50-400

1.0 INTRODUCTION

Duke Energy Progress, LLC (previously known as Duke Energy Progress Inc., Progress Energy Carolinas, Inc. and Carolina Power & Light Company) received a low-power Facility Operating License (No. NPF-53) and full-power Facility Operating License (No.

NPF-63) for the Shearon Harris Nuclear Power Plant (HNP), Unit 1, from the U.S.

Nuclear Regulatory Commission (NRC) on October 24, 1986, and January 12, 1987, respectively. The NRC issued a Renewed Facility Operating License (No. NPF-63) on December 17, 2008, extending operations until October 24, 2046. Appendix B (the Environmental Protection Plan (EPP) [Nonradiological]) of the renewed operating license requires submittal of an Annual Environmental (Nonradiological) Operating Report to the NRC describing the implementation of the plan during the previous year. The purpose of this document is to fulfill the requirement for the period January 1 through December 31, 2020.

On September 18, 2015, The North Carolina Department of Environment and Natural Resources (NCDENR) officially became the North Carolina Department of Environmental Quality (NCDEQ) when Governor McCrory signed the 2015-2016 state budget into law. NCDEQ will be used in this report.

2.0 PLANT CONSISTENCY REQUIREMENTS [EPP Section 3.0]

2.1 Plant Design and Operation There were no changes in plant design or operation and there were no tests or experiments performed which involved a potentially significant unreviewed environmental question during the reporting period.

2.2 Reporting Related to the NPDES Permit As required by National Pollutant Discharge Elimination System (NPDES) permit NC0039586, monitoring data was submitted to the NCDEQ via monthly discharge monitoring reports and separate correspondence as warranted.

The renewed NPDES permit NC0039586 became effective on September 1, 2016 by NCDEQ. This permit will expire on August 31, 2021. HNP submitted a copy of the renewed permit to the NRC by letter dated September 28, 2016, as required by Renewed Facility Operating License No. NPF-63 Appendix B.

3.0 UNUSUAL OR IMPORTANT ENVIRONMENTAL EVENTS [EPP Section 4.1]

No occurrence of an unusual environmental event that would indicate or could result in a significant environmental impact causally related to plant operations occurred during the reporting period. No releases or exceedances of permit conditions caused any significant environmental impact. The existence of biofouling organisms (Asiatic clams, Corbicula fluminea) and the presence of troublesome aquatic vegetation (hydrilla, Hydrilla verticillata) in the Harris Reservoir are considered important topics worthy of inclusion in this report. No zebra mussels were detected at any location in the Harris Lake or the auxiliary reservoir during 2020.

3.1 Aquatic Biological Monitoring A. Inspections for Asiatic clams (Corbicula fluminea) in the Harris Nuclear Plant Emergency Service Water System (e.g., intake structures)

The Emergency Service Water (ESW) intake structure is inspected once every four years in accordance EPT-168 (Engineering Performance Test) and Periodic Maintenance Identification Numbers (PMIDs) 23528 and 23529 as part of HNPs Generic Letter 89-13 Testing and Inspection Program.

Inspections of the ESW screening structure bays ESW B Bay 6, 1X CTMU (Cooling Tower Make-up) and 1&2X CTMU occurred during 2019.

There were no inspections in 2020.

No clogging events of HNP cooling water systems were observed during 2020 because of Asiatic clam infestation.

B. Monitoring aquatic vegetation Main Reservoir North Carolina Division of Water Resources (DWR) conducted an aquatic vegetation survey in the reservoir in the fall of 2020. No hydrilla was observed in the reservoir or in the intake embayment or canal. Black Mat Algae (Lyngbya species) was found in the reservoir but at lower levels than in 2019. A new species, Aquatic Moss (Fontinalis species), was detected in the survey. There is no operational risk or concern posed by the new species.

Auxiliary Reservoir No Hydrilla, American Elodea, Bladderwort, or Southern Pond Weed was observed in the auxiliary reservoir, intake canal, or along the shoreline adjacent to the auxiliary intake canal in 2020. There were a few small areas of Baldwins Spikerush (Eleochris baldwinii) and a few scattered areas of Alligator Weed (Alternanthera philoxeroides) and Creeping Water Primrose (Ludwigia spp.), but only in very small amounts. No submerged aquatic vegetation was observed in the intake canal and embayment. The scant amount of aquatic vegetation does not pose any operational concerns.

No impacts to HNP operations from aquatic vegetation occurred in 2020.

3.2 Combined Construction and Operating License Application Evaluations In a letter dated February 18, 2008, Carolina Power & Light Company applied for a combined construction permit and operating license (COL) for two AP1000 advanced pressurized water reactor units to be located at the HNP site. In the initial application, Carolina Power & Light Company relied on Integrated Resource Plans (IRPs) prepared for the North Carolina Utilities Commission and the Public Service Commission of South Carolina to demonstrate the need for the two units. The IRPs used a 15-year period for forecasting native load requirements, supply-side and demand side resources, and options considered for satisfaction of the load requirements and other system obligation. Duke Energy Progress, LLC (DEP) continued to evaluate the need for power, however the commercial operation dates for the two units no longer fell within the 15-year planning window of the IRP. DEP requested an additional exemption in a [[letter::HNP-16-081, Mitigating Strategies Assessment (MSA) Report for the New Seismic Hazard Information - NEI 12-06, Appendix H, Revision 2, H.4.2 Path 2: GMRS 6; SSE with High Frequency Exceedances|letter dated October 13, 2016]], to the NRC. The NRC renewed the exemption through December 31, 2019. DEP requested on December 2, 2019 to extend the exemption date to December 31, 2024. The NRC approved the request on April 6, 2020.

No work was performed in 2020 in support of the COL for the two units at the HNP site.

3.3 Harris Land Sales Two large sales of property outside of the Owner Controlled Area occurred in 2020.

Project Galaxy: Harris Plant Land Sale On August 27, 2020, DEP sold 139.976 acres to Helix Ventures, LLC. The deed is recorded in the Wake County Register of Deeds under Deed Book 18040, Page 1512. The buyer - a developer - is finalizing a deal with a large life sciences (biomanufacturing) company planning to locate a new campus on this site with the support of (Town of) Holly Springs Economic Development.

Holly Springs Wastewater Expansion: Harris Plant Land Sale On December 30, 2020, DEP sold 30.9499 acres to the Town of Holly Springs.

The deed is recorded in the Wake County Register of Deeds under Deed Book 18267, Page 2717. This property will be utilized for expansion of the Towns adjacent wastewater treatment plant, which is needed due to the substantial growth and development of the area. As part of the deal, DEP reserved an easement to continue to be able to access its adjacent lands; this access easement is recorded in the Wake County Register of Deeds under Deed Book 18267, Page 2723 No significant environmental impacts have been caused or identified by these activities 3

4.0 ENVIRONMENTAL MONITORING [EPP Section 4.2]

4.1 Aquatic Monitoring [EPP Section 4.2.1]

Under the authority of the Clean Water Act, the state of North Carolina renewed the HNP NPDES permit (NC0039586) which took effect on September 1, 2016.

The permit includes the Harris Energy & Environmental Center sewage treatment plant discharge as an outfall (007).

The permit requires that a state-certified laboratory perform the analyses on all non-field parameters analyzed for effluent samples. In accordance with this requirement, the HNP Environmental & Chemistry Laboratory was certified by NCDEQ as a Wastewater Laboratory, effective January 1, 2020, and valid through December 31, 2020. In addition, the Duke Energy Carolinas Laboratory in Huntersville, NC, provided NPDES analytical support for effluent samples.

During 2020, DEP also contracted with three NCDEQ certified private laboratories (Environmental Testing Solutions, Inc. (ETS), GEL Laboratories (GEL), and PACE Analytical Laboratories (PACE)) to perform analyses.

4.1.1 Effluent Monitoring Routine effluent monitoring was conducted and reported to NCDEQ as required by the NPDES permit. There were no NPDES permit noncompliances or events in 2020.

4.1.2 NPDES Inspections NCDEQ, Division of Water Resources personnel visited HNP and the Harris Energy & Environmental Center to conduct a review of the domestic wastewater treatment plants on February 27, 2020.
