Duke Energy Progress, LLC Shearon Harris Nuclear Power Plant Unit 1 ANNUAL ENVIRONMENTAL (NONRADIOLOGICAL)

OPERATING REPORT January 1, 2018 through December 31, 2018 Renewed Facility Operating License No. NPF-63 Appendix B Docket No. 50-400

1.0 INTRODUCTION

Duke Energy Progress, LLC (Duke Energy, 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, Unit 1 (HNP), 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, 2018.

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 North Carolina Department of Environmental Quality (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 Asiatic clams were detected at any location in the Harris Lake 1

or the auxiliary reservoir during 2018.

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 eight years in accordance with an Engineering Periodic Testing (EPT) procedure EPT-163 and periodic maintenance identification numbers 23528 and 23529 as part of HNPs Generic Letter 89-13 Testing and Inspection Program. No inspections of an ESW screening structure bay occurred during 2018.

No clogging events of HNP cooling water systems occurred as a result of Asiatic clam infestation during 2018.

B. Monitoring aquatic vegetation Main Reservoir Hydrilla was found in much of the main reservoir during 2018. Hydrilla and creeping water primrose were abundant and filled most of the available habitat at Transect S upstream of the New Hill-Holleman Rd. causeway. Hydrilla was not observed in Transect V or in the shallow bay adjacent to the mouth of the main intake canal. In the mid-lake area (Holleman Boat Ramp), hydrilla was present in variable amounts, but appears reduced from previous years. Prior to 2008, the Buckhorn Creek arm of the lake was primarily supporting hydrilla, but now primarily supports a large lyngbya algal population.

Lyngbya is also present throughout the embayment near the dam and the Cross-Point Boat launch. Other aquatic plant species found in the reservoir include fanwort (Cabomba species), and typical Atlantic slope Piedmont species such as Chara species, spikerush (Eleocharis baldwinii), and native pondweed species in the genera Potamogeton and Najas. The shoreline aquatic plant community is typical of Piedmont reservoirs including such plants as cattails, pickerelweed, lizard tail, bulrush, and others.

No new species of aquatic plants were observed in the main reservoir.

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 2018. The dominant vegetation observed along the auxiliary intake canal was Eleochris baldwinii, a small grass-like submerged plant that poses no operational concern. Creeping water primrose (Ludwigia spp.) was also present but in small amounts. There were 100 Grass Carp stocked in the auxiliary reservoir in 2018.

No impacts to HNP operations from aquatic vegetation occurred in 2018.

3.2 Combined Construction and Operating License Application In a letter dated Feb 18, 2008, Carolina Power & Light Company (CP&L) submitted an application for a combined construction permit and operating license (COL) for two AP1000 advanced pressurized water reactor units to be located at the Shearon Harris 2

Nuclear Power Plant site. In the initial application, CP&L 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 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. As a result, in a letter to the NRC dated May 2, 2013, DEP requested suspension of the COL for the two units at the Shearon Harris Nuclear Power Plant site.

No work was performed in 2018 in support of the COL for the two units at the Shearon Harris Nuclear Power Plant site.

No significant environmental impacts have been caused or identified by these activities.

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 (HE&EC) 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, 2018, and valid through December 31, 2018. In addition, the Duke Energy Carolinas Laboratory in Huntersville, NC, provided NPDES analytical support for effluent samples.

In addition, during 2018 Duke Energy contracted with three NCDEQ certified private laboratories to perform analyses, including: Environmental Testing Solutions, (ETS),

GEL Laboratories (GEL), and PACE Analytical Laboratories (PACE).

4.1.1 Effluent Monitoring Routine effluent monitoring was conducted and reported to NCDEQ as required by the NPDES permit. The following NPDES permit event occurred.

  • January 2018, Fecal Coliform Exceedance - The fecal coliform daily maximum, in colony-forming units (CFUs), of 400 CFU/100 mL was exceeded on January 31, 2018 for the HNP Sewage Treatment Plant (STP). The result of 1,600 CFU/100 mL was recorded in the January 2018 Discharge Monitoring Report for Outfall 002.

Possible Causes:

1. Prior to sampling, the ultraviolet (UV) lamps were cleaned which possibly caused contaminates that had accumulated on the UV lamps or the quartz sleeve to be displaced into the sample container.

3

2. Reduced light wave intensity on UV lamps due to age of lamps. Manufacturer recommendation for replacement of lamps is one year. The entire bank of UV lamps in Control building #1 was replaced on May 4, 2017 and one UV lamp was replaced on November 13, 2017.
3. Extended cold weather slows nitrification in system. Influent flow goes directly into RST-1 which is an open tank and temperature of influent water is weather dependent. Cold water from RST-1 is distributed throughout the system.

Corrective Actions:

1. Chemistry Operator Rounds Guide updated to state clean UV lamps after sampling to allow for the system to settle prior to next day sampling.
2. All UV lamps and quartz sleeves were replaced by vendor on February 2, 2018.

Schedule UV lamp replacement every 6 months.

The February 06 and February 13, 2018 fecal coliform sample results were <1 CFU/100 mL for both samples.

No impacts to the environment were observed.

4.1.2 NPDES Inspections On June 27, 2018, NCDEQ, Division of Water Resources personnel visited HNP and the HE&EC to conduct a review of the domestic wastewater treatment plants.

No violations were identified.

4.2 Terrestrial Monitoring [EPP Section 4.2.2]

Terrestrial monitoring is not required.

4.3 Noise Monitoring [EPP Section 4.2.3]

Noise monitoring is not required.

5.0 EPP REVIEW and AUDIT [EPP Section 5.1]

Duke Energy provides for the review and audit of compliance with the EPP on a periodic frequency. The results of these reviews and audits are on file and available for inspection.

6.0 PLANT REPORTING REQUIREMENTS [EPP Section 5.4]

6.1 EPP Noncompliances There were no EPP noncompliances identified during the reporting period.

NPDES permit noncompliances are discussed in Section 4.1.1 of this report.

4

6.2 Changes in Station Design and Operation There were no changes in station design or operation and there were no tests or experiments performed which involved a potentially significant unreviewed environmental question during 2018.

6.3 Non-routine Reports There were no additional non-routine reports submitted in accordance with EPP Section 5.4.2 aside from those mentioned in Section 4.1.1.

6.4 Other Reporting Requirements There were no other EPP reportable events during 2018.
