N/A—New permit New expiration date 10/31/2028 Comments on Draft Permit? See Section 6 below Section 1. Facility Activities and Process: The Harris Nuclear Plant (HNP) is a nuclear electricity generating facility consisting of a 964 megawatt generating unit and associated facilities. The Harris Energy and Environmental Center(HEEC) includes facilities that provide support services (laboratories and training) for the HNP and other Duke Energy Progress, LLC facilities. The outfalls in this permit were previously permitted under NPDES wastewater permit NC0039586. Per the NCO039586 permit renewal application submitted to the Division of Water Resources (DWR) in 2021, stormwater runoff is composed of laydown yards, training areas, parking lots, roofs, and lawn drainage. Outside storage areas. Flow from these areas is estimated at 8.8 million gallons per month, based on average rainfall of 43 inches per year and a runoff assumption factor of 0.7. Per the NCO039586 permit renewal application, miscellaneous sources of water intermittently discharged to storm drains are: • Heat exchanger on the demineralizer feedwater: It is necessary to heat the source water to the demineralized water treatment system to achieve optimum degassification. To accomplish this, steam is used to heat the feedwater. The condensed steam is discharged to the storm drains that flow to Harris Lake at approximately 5-10 gallons per minute. This steam could contain trace amounts of hydrazine and ammonia used for chemistry control in the auxiliary boiler steam system. Due to the low flow rate and the long retention time, the temperature of the condensed steam should be at ambient temperature upon reaching the lake. • Condenser water box drains: Prior to condenser maintenance or repairs it is sometimes (approximately twice/year) necessary to drain circulating water to the storm drains approximately 60,000 gallons per condenser per event)that discharge to Harris Lake. This water is monitored for selected cooling tower blowdown parameters. • Filtered water storage and Derain water storage tanks: Water is treated using a micro-filtration unit for turbidity control and then stored in a tank prior to subsequent filtration(nano-filtration Page 1 of 16 unit) and disinfection. Occasionally, some water from these tanks may be drained to the storm drains that discharge to Harris Lake. This water may contain trace amounts of chlorine. • Fire protection system: Approximately 5,000 gallons of lake water used for annual testing of the fire protection system is routed to most of the storm drains that discharge to Harris Lake. In the event of a fire, additional water could be discharged to storm drains. • Condenser hotwell: During outages (approximately once per 18 months) it is necessary to drain the condenser hotwell for condenser maintenance and inspection. Approximately 70,000 gallons of this water resulting from condensed steam is drained to storm drains that discharge to Harris Lake. It may contain trace amounts of ethanolamine, 100 ppb or less of boron, and 100 ppb or less ammonia. • Condensate storage tank: Infrequently it is necessary to drain the condensate storage tank for maintenance. Approximately 400,000 gallons per event is drained to storm drains that discharge to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia, and trace hydrazine. • Air conditioning system condensate: The condensate from various building air conditioning systems flows to various storm drains to Harris Lake. The volume is generally low and is greatest in the humid summer months. • Service water system strainers: Infrequently, when service water strainers located at the makeup pumps from the cooling tower basin are backwashed to remove biofouling organisms or debris, a small volume of service water overflows the basin and runs to the adjacent storm drain that discharge to Harris Lake. • Maintenance activities: During maintenance activities at the facility it may become necessary to drain all or some portion thereof of the following plant systems: normal service water, emergency service water, circulating water,potable water, and demineralized water. Maintenance activities at the facility may also require the hydrostatic flushing of system piping with discharge to the storm drain system. In addition, the facility may find it necessary to wash equipment with demineralized water and discharge to the storm drains.

Stormwater runoff discharges via overland flow to the Emergency Service Water Intake Canal (no discharge ends up in the lake; water from this canal goes into the facility, therefore is handled under the wastewater permit). Significant potential pollutants include: Lead from expended ammunition, mineral oil, raw sewage overflow, miscellaneous trash (from dumpster), oils, gasoline, and diesel fuel. Note: DA-10 does not contain an outlet structure. SW-A: Drainage Area A Drainage area includes non-industrial use grassed areas. Stormwater runoff from this area discharges through a ditch into Harris Reservoir north of the causeway. There are no significant potential pollutants. Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge from any conveyance that is used for collecting and conveying storm water and that is directly related to manufacturing,processing or raw materials storage areas at an industrial plant. The term does not include discharges from facilities or activities excluded from the NPDES program under this part 122. For the categories of industries identified in this section, the term includes, but is not limited to, storm water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled by carriers of raw materials, manufactured products, waste material, or byproducts used or created by the facility; material handling sites; refuse sites; sites used for the application or disposal of process waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of material handling equipment; sites used for residual treatment, storage, or disposal; shipping and receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and intermediate and final products; and areas where industrial activity has taken place in the past and significant materials remain and are exposed to storm water. For the purposes of this paragraph, material handling activities include storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product, byproduct or waste product. The term excludes areas located on plant lands separate from the plant's industrial activities, such as office buildings and accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm water [sic] drained from the above described areas." Page 5 of 16 Section 2. Monitoring Information and Compliance History: • No tiered response information available as this is a new permit application • No analytical monitoring data for stormwater outfalls available for review as NPDES wastewater permit only has qualitative data monitoring required Threatened/Endangered Species: There are no threatened/endangered species at the discharge location, but there is a species of concern in the area: Regal Darner(Coryphaeschna ingens; NC status: SR) Section 3. Proposed Monitoring for Stormwater Discharges: The Division considered potential pollutants from past and present industrial activities (nuclear electric generation). There are no analytical results to review as the outfalls covered under the existing wastewater NPDES permit do not require analytical monitoring (visual monitoring only required). Unlike most stormwater permits in its program, the Division is proposing a permit structure with outfall- specific monitoring for discharges. Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases, dependent upon future activities. Below is a table of the proposed monitoring for each outfall at the Harris Nuclear plant site. All outfalls discharge to the Shearon Harris Reservoir.

Stormwater benchmarks are numerical action levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark concentrations are intended as guidelines for the facility's development and implementation of the Stormwater Pollution Prevention Plan(SWPPP). Benchmark exceedances require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a tiered approach to specify actions the permittee must take in response to analytical results above Page 10 of 16 benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide flexibility to address issues that may arise with one or more parameters and/or outfalls. Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of DWR. NC DWR follows established federal procedures for calculating acute standards when developing the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L. Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this approach because of the ephemeral nature of rainfall events. The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or ash removal in specific drainage areas at this site. For parameters that do not have a stormwater benchmark, the Division may develop a benchmark value if appropriate toxicity data become available or if rising trends in concentrations suggest a persistent source. A summary of the benchmarks in the draft permit, and their basis, is below: Parameter Benchmark Basis '/2 FAV; Based on (Cr III+ Cr VI) acute thresholds and Chromium(Total) 905 µg/L assumption that industrial activities here are not a source of hexavalent chromium Copper Total 10 /L Acute Aquatic Criterion, 1/2 FAV Assume all chromium III in most cases; chromium VI Chromium (Total) 905 µg/L only if suspected source; 1/2 FAV EPA's National Recommended Water Quality Criteria(Acute) for dissolved chromium III Lead Total 75 µg/L Acute Aquatic Criterion, '/2 FAV Nickel Total 335 /L Acute Aquatic Criterion, 1/2 FAV Zinc Total 126 /L Acute Aquatic Criterion, 1/2 FAV Total Residual Chlorine 28 /L 1/2 FAV NC's calculation, not EPA's Total Nitrogen 30 mg/L TKN+Nitrate+Nitrite Benchmarks (Expressed in mg/L of N Ammonia Nitrogen Based on the mussels-present/trout absent acute criteria summer 5.6 mg/L table in the 2013 EPA criteria document Ammonia Nitrogen Based on the mussels-present/trout absent acute criteria winter 15 mg/L table in the 2013 EPA criteria document Fecal Coliform 1,000 Based on geometric mean of 10+ samples/year col/100 mL BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation(40 CFR g 133.03 COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic wastewaters Total Suspended Solids 100 mg/L National Urban Runoff Program (NURP) Study, 1983 TSS Page 11 of 16 H 6 s.u. —9 NC Water Quality Standard (Range) p S.U. Non-Polar Oil & Review of other state's daily maximum benchmark Grease, EPA Method 15 mg/L concentration for this more targeted O&G; NC WQS that 1664 SGT-HEM does not allow oil sheen in waters Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's pollution prevention approach to stormwater permitting. The Division's maintains that implementation of Best Management Practices (BMPs) and traditional stormwater management practices that control the source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are designed to be flexible requirements for implementing site-specific plans to minimize and control pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT. Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an alternative monitoring plan for approval by the Region: • Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer may direct the response actions on the part of the permittee as provided in Tier Three, including reduced or additional sampling parameters or frequency. • If pursuing the alternative above after two consecutive exceedances, the permittee may propose an alternative monitoring plan for approval by the Regional Engineer. The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For example, the permittee may request that mercury only be monitored semi-annually under the tiers, or that only parameters over the benchmark be monitored more frequently. In this way, changes to the monitoring scheme for any outfall could be handled outside of a permit modification. Other Proposed Requirements: • It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an annual certification that stormwater outfalls have been evaluated for the presence of non- stormwater discharges, and if any are identified, how those discharges are permitted or otherwise authorized. • Requirement to submit a request for permit modification if the facility identifies or creates any new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants. • The Division expects the permittee to apply best professional judgment and consider the safety of its personnel in fulfilling sampling obligations under the permit. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the EPA. • Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout year. Page 12 of 16 Section 4. Changes from draft to final: • Monitoring for chromium, iron, and nickel removed from all outfalls as monitoring for copper, lead, and zinc are sufficient for monitoring metals • Monitoring for BOD removed from SW003, SW004, and SWO12 • Permit condition added for ammonia nitrogen allowing monitoring to cease after 4 sample results below detection Section 5. Discussions with the Facility and Regional Office: • Initial contact with facility: 3/9/22 • Initial contact with Regional Office: 3/9/22 • Draft sent to CO peer review: 1/17/2023 • Draft sent to Regional Office: 6/14/2023 • Final permit sent for supervisor signature: 9/14/2023 Section 6. Comments received on draft permit: • Shawn Guyer (PWS; via email 7/3/2023): The PWS Section concurs with the issuance of this permit provided the facility is operated and maintained properly, the stated effluent limits are met prior to discharge, and the discharge does not contravene the designated water quality standards. • Don Safrit(Duke Energy; via email 7/10/2023): The two biggest concerns we have with the draft permit are the benchmarks assigned to each of the outfalls and whether we could have the opportunity to begin the permit cycle with ROS status for some of our outfalls like you allowed us to do at the McGuire Nuclear Plant. To provide complete comments on the draft permit and create an opportunity for us to collaborate on benchmarks and ROS, we have two requests for you: 1. We would like to have a site visit with the DEMLR Central and Raleigh Regional Offices to discuss the benchmarks and ROS, considering the industrial activities and materials at the plant. Our data/site conditions demonstrate that it is not necessary to retract the ROS and believe a site visit would be instrumental in providing the agency with the information needed to evaluate our proposal ; and 2. We would like to have an extension to respond with specific comments on the benchmarks and ROS until two weeks after the date of the site visit. We would then like to set the new deadline. • Don Safrit(Duke Energy; via mail 8/14/2023): 1. ROS request has been submitted to the Raleigh Regional Office. Duke Energy requests that the ROS be reviewed and acted upon prior to issuance of the new permit. NC DEQ has historically allowed ROS at SW-003 and SW-006 at the HNP for the existing NPDES Wastewater Permit. ■ DEMLR Response: ROS requests and permit issuance are two separate processes. ROS is handled by the Regional Office while permit issuance is Page 13 of 16 handled by the Central Office. The Division cannot guarantee ROS will or will not be granted, therefore the permit review will move forward. 2. Based on the ROS request and review of general permits for similar industrial activities, Duke Energy requests certain monitoring parameters for the representative outfalls. Duke Energy would like to note that the monitoring parameters for SW-006 exceed those proposed in the current draft permit. ■ DEMLR Response: Per the Raleigh Regional Office, a determination cannot be made without sample data to support the request. Once you have at least four(4) samples, ROS can be re-requested. 3. Duke Energy requests removal of non-polar oil & grease and monthly oil usage from the monitoring parameters. Duke Energy has established procedures to minimize or ensure no exposure of oil,petroleum products, and other chemicals to stormwater. ■ DEMLR Response: Monitoring for non-polar oil & grease and monthly oil usage are standard monitoring parameters of all individual stormwater permits. Although practices may be in place to minimize exposure, as there is still potential for exposure in the drainage areas, monitoring shall remain in the permit. 4. Duke Energy requests removal of COD from the monitoring parameters. Duke Energy has established procedures to minimize exposure of chemicals used on site to stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of COD. ■ DEMLR Response: Due to the type of chemicals and activities that occur in the drainage areas, monitoring for COD shall remain in the permit. If exceedances occur in monitoring results, Duke Energy may submit documentation to the Division with further information regarding the causes of the exceedances. 5. Duke Energy requests removal of BOD from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g. deer, geese, turkeys, and many others)population on-site, which would be a significant source of this pollutant. No industrial processes at the site are expected to be a source of BOD. ■ DEMLR Response: Monitoring for BOD has been removed from outfalls SW003, SW004, and SW012. Monitoring for BOD shall remain for outfalls SW001, SW002, SW005, and SW006 due to the presence of lift stations in the drainage areas, and in outfalls SW008 and SW009 due to the presence of wood pallet storage. 6. Duke Energy requests removal of total residual chlorine from the monitoring parameters. Total residual chlorine is monitored under the existing wastewater NPDES permit (NC0039586) at the outfalls requested for ROS. Duke Energy has established procedures to minimize exposure to stormwater. ■ DEMLR Response: Monitoring for TRC was included in the draft permit as the drainage area has a chlorine tank. Although practices may be in place to minimize exposure, as there is still potential for exposure in the drainage areas, monitoring shall remain in the permit. 7. Duke Energy requests removal of fecal coliform from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others)population on-site, which would be a significant source of this pollutant. While sewage lift stations are located on site, they are operated as part of the wastewater treatment system which operates and is monitored under the existing wastewater NPDES permit (NC0039586). HNP employs robust spill response procedures aimed at ensuring environmental compliance and protection of employees, public health and the environment. Except for operating the wastewater treatment plant, which is Page 14 of 16 permitted separately, no industrial processes are expected to be a source of fecal coliform. ■ DEMLR Response: As there are lift stations in the drainage areas, monitoring for fecal coliform shall remain in the permit. If exceedances occur in monitoring results, Duke Energy may submit documentation to the Division with further information regarding the causes of the exceedances. 8. Duke Energy requests removal of ammonia nitrogen from the monitoring parameters. The ammonia tank in Drainage Area 5 (SW-005) is abandoned and has been closed. Duke Energy is willing to consider re-cleaning the tank to provide appropriate documentation for closure to NC DEQ DEMLR if requested. No active industrial processes at the site are expected to be a source of ammonia nitrogen. ■ DEMLR Response: A condition will be added that the permittee may cease monitoring after four(4) consecutive samples show results below detection. If the tank should ever hold ammonia nitrogen, or some other substance, in the future, Duke Energy shall notify the Division and request a permit modification as early as possible to ensure proper permit coverage. 9. Duke Energy requests removal of total nitrogen from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others)population on-site, which would be a significant source of this pollutant. Duke Energy employs the practices to minimize exposure to stormwater. ■ DEMLR Response: As there is a liquid nitrogen storage tank in the SW005 drainage area and lift stations in the SW001 drainage area, monitoring shall remain. If exceedances occur in monitoring results, Duke Energy may submit documentation to the Division with further information regarding the causes of the exceedances. 10. Duke Energy requests removal of total chromium from the monitoring parameters. Total chromium is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas. One historic process at the plant used chromium, but that process is no longer active and was conducted inside the main plant building in Drainage Area 6 (SW-006). No active industrial processes are expected to be a source of total chromium and thus has no reasonable potential to be in the industrial stormwater. ■ DEMLR Response: Monitoring for copper, lead, and zinc shall be sufficient to determine stormwater exposure to scrap metals stored in the drainage areas. Monitoring for total chromium will be removed from the permit. 11. Duke Energy requests removal of total nickel from the monitoring parameters. Total nickel is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas. No industrial processes at the site are expected to be a source of total nickel and thus has no reasonable potential to be in the industrial stormwater. ■ DEMLR Response: Monitoring for copper, lead, and zinc shall be sufficient to determine stormwater exposure to scrap metals stored in the drainage areas. Monitoring for total nickel will be removed from the permit. 12. Duke Energy requests removal of total iron from the monitoring parameters. Total iron is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas. In 2015, the NC DEQ DWR removed iron from the surface water standards when assessment reports indicated exceedances of the iron criteria in every basin. Evaluations of elevated levels did not correlate with individual dischargers, urban settings nor mining operations. Page 15 of 16 ■ DEMLR Response: Monitoring for copper, lead, and zinc shall be sufficient to determine stormwater exposure to scrap metals stored in the drainage areas. Monitoring for total iron will be removed from the permit. 13. The lay down storage area in Drainage Area 5 (SW-005) is temporary due to construction and will no longer be utilized for outdoor storage when construction is completed. Construction is scheduled to be completed by DATE. Duke Energy is willing to submit a lay down area consolidation plan by March 31, 2024, to facilitate ROS for the remainder of the outfalls. The lay down area consolidation plan would include a proposal for consolidating outdoor storage areas that can be moved and cover of those that cannot. ■ DEMLR Response: A permit modification request can be submitted at the time the laydown storage area is no longer utilized. Monitoring as permitted shall continue until that time. 14. Per discussion with NC DEQ DEMLR on July 27, 2023, if NC DEQ DEMLR does not agree with Duke Energy's assessment to justify removal of total chromium, total nickel, and COD as monitoring parameters after the site visit, Duke Energy is willing to consider sampling for a year(four(4) quarterly samples) to justify removal of these parameters from monitoring if results indicate levels are detected below the proposed benchmarks. ■ DEMLR Response: Monitoring for total chromium and total nickel has been removed from the permit. Monitoring for COD shall remain in the permit due to the type of chemicals and activities that occur in the drainage areas.

Good afternoon Don, I apologize for my delay in response. As I mentioned on the phone, Lauren is leaving the Raleigh Regional Office so Thad Valentine is the regional office contact for now. I have copied him on this email chain.You mentioned the Harris Nuclear Plant folks would like to have an onsite meeting to go over the draft permit and walk around the site to observe outfalls for ROS discussion. Given staff availability restraints, I am not sure an onsite meeting will be possible, but we can pursue that avenue to start. When are Duke Energy representatives available for a discussion on the permit? If we are unable to meet in person, having photos taken to present during a Teams meeting will be helpful.

Brianna, 5 Thank you for sharing the draft Harris Nuclear Plant permit and providing us with the opportunity to comment. The two biggest concerns we have with the draft permit are the benchmarks assigned to each of the outfalls and whether we could have the opportunity to begin the permit cycle with ROS status for some of our outfalls like you allowed us to do at the McGuire Nuclear Plant. To provide complete comments on the draft permit and create an opportunity for us to collaborate on benchmarks and ROS, we have two requests for you: 1. We would like to have a site visit with the DEMLR Central and Raleigh Regional Offices to discuss the benchmarks and ROS, considering the industrial activities and materials at the plant. Our data/site conditions demonstrate that it is not necessary to retract the ROS and believe a site visit would be instrumental in providing the agency with the information needed to evaluate our proposal ; and 2. We would like to have an extension to respond with specific comments on the benchmarks and ROS until two weeks after the date of the site visit. We would then like to set the new deadline. Please let me know your thoughts and I am happy to answer any questions you may have. Thanks, Don Donald(Don)Safrit, P.E.

To facilitate ROS, Duke Energy proposes monitoring these additional parameters at SW-006_ Non-Polar Oil & Grease, Monthly Oil Usage Comment 3: Duke Energy requests removal of non-polar oil & grease and monthly oil usage from the monitoring parameters. Duke Energy has established the following procedures to minimize or ensure no exposure of oil, petroleum products, and other chemicals to stormwater: All storage tanks and the associated loading/unloading areas are located within secondary containment. Depending on the material in containment, water in the secondary containment is either emptied back into the process, treated by an oil water separator and discharged to the sanitary sewer for additional treatment, or removed by a contractor after testing. No stormwater from secondary containment is discharged to the environment. See Figure 3. As a redundant measure of safety, secondary containment outlets are locked and equipped with "Petro Plugs," which solidify when exposed to oil or petroleum products. The Petro Plugs are a backup in case the outlet fails or is left open and will prevent stormwater containing oil or petroleum products from passing through the outlet. Loading and unloading to all tanks is performed in secondary containment. The loading and unloading areas have been constructed to ensure hoses and piping are located within the containment to prevent exposure. See Figure 3. Except for very large equipment (e.g., cranes) and fixed transformers in Drainage Areas 2 and 3 (SW-002 and SW-003), vehicle and equipment maintenance are performed off-site. On the occasions when fixed transformers or very large equipment require routine maintenance on site, temporary secondary containment is deployed during such maintenance activities.

HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. No industrial processes at the site are expected to be a source of BOD. Duke Energy employs the following practices to minimize exposure to stormwater: Dumpsters that contain general refuse are scheduled for emptying weekly and the lids are closed when not in use. The trash compactor located on site is not open to rainwater and is not expected to contact stormwater. Fertilizer is not applied as part of landscape management. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated BOD was undetectable or detected at levels significantly below the proposed benchmarks. Table 6.

Total Residual Chlorine Comment 6: Duke Energy requests removal of total residual chlorine from the monitoring parameters. Total residual chlorine is monitored under the existing wastewater NPDES permit (NC0039586) at the outfalls requested for ROS. Duke Energy has established the procedures described above to minimize exposure to stormwater as well as the following specific procedures: The chlorine tank in Drainage Area 3 (SW-003) and the loading/unloading area are located within secondary containment which drains back to the process water and is not discharged to the environment. The cooling system employs a dichlorination system. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of total residual chlorine.

Comments—Draft NPDES Storm water Permit NCS000606 Serial: RA-23-0213 Enclosures Fecal Coliform Comment 7: Duke Energy requests removal of fecal coliform from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. While sewage lift stations are located on site, they are operated as part of the wastewater treatment system which operates and is monitored under the existing wastewater NPDES permit (NC0039586). HNP employs robust spill response procedures aimed at ensuring environmental compliance and protection of employees, public health and the environment. Except for operating the wastewater treatment plant, which is permitted separately, no industrial processes are expected to be a source of fecal coliform. Ammonia Nitrogen Comment 8: Duke Energy requests removal of ammonia nitrogen from the monitoring parameters. The ammonia tank in Drainage Area 5 (SW-005) is abandoned and has been closed. Duke Energy is willing to consider re-cleaning the tank to provide appropriate documentation for closure to NC DEQ DEMLR if requested. No active industrial processes at the site are expected to be a source of ammonia nitrogen. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of ammonia. Table 8. Samolina from 2022 braft Permit Parameter SW-003 l .

Total Nitrogen Comment 9: Duke Energy requests removal of total nitrogen from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. Duke Energy employs the following practices to minimize exposure to stormwater: While a nitrogen aboveground storage tank (AST) is located on site, the tank contains nitrogen in a gaseous form used to purge lines. A release from the tank would be to the atmosphere and would not have an impact to stormwater. No industrial processes at the site are expected to be a source of total nitrogen to stormwater runoff. Fertilizer is not applied as part of landscape management. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated total nitrogen was detected significantly below the proposed benchmarks. Table 9.

Total chromium is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas ( Table 10). One historic process at the plant used chromium, but that process is no longer active and was conducted inside the main plant building in Drainage Area 6 (SW-006). No active industrial processes are expected to be a source of total chromium and thus has no reasonable potential to be in the industrial stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated total chromium was undetectable or detected at levels significantly below the proposed benchmarks.

Total nickel is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas ( Table 12). No industrial processes at the site are expected to be a source of total nickel and thus has no reasonable potential to be in the industrial stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated nickel was undetectable or detected significantly below the proposed benchmarks. Table 12.

Total iron is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas (see Table 14). In 2015, the NC DEQ DWR removed iron from the surface water standards when assessment reports indicated exceedances of the iron criteria in every basin. Evaluations of elevated levels did not correlate with individual dischargers, urban settings nor mining operations. Table 14.

The lay down area consolidation plan would include a proposal for consolidating outdoor storage areas that can be moved and cover of those that cannot. Comment 14: Per discussion with NC DEQ DEMLR on July 27, 2023, if NC DEQ DEMLR does not agree with Duke Energy's assessment to justify removal of total chromium, total nickel, and COD as monitoring parameters after the site visit, Duke Energy is willing to consider sampling for a year (four (4) quarterly samples) to justify removal of these parameters from monitoring if results indicate levels are detected below the proposed benchmarks.

To facilitate ROS, Duke Energy proposes monitoring these additional parameters at SW-006. Non-Polar Oil & Grease, Monthly Oil Usage Comment 3: Duke Energy requests removal of non-polar oil & grease and monthly oil usage from the monitoring parameters. Duke Energy has established the following procedures to minimize or ensure no exposure of oil, petroleum products, and other chemicals to stormwater: All storage tanks and the associated loading/unloading areas are located within secondary containment. Depending on the material in containment, water in the secondary containment is either emptied back into the process, treated by an oil water separator and discharged to the sanitary sewer for additional treatment, or removed by a contractor after testing. No stormwater from secondary containment is discharged to the environment. See Figure 3. As a redundant measure of safety, secondary containment outlets are locked and equipped with "Petro Plugs," which solidify when exposed to oil or petroleum products. The Petro Plugs are a backup in case the outlet fails or is left open and will prevent stormwater containing oil or petroleum products from passing through the outlet. Loading and unloading to all tanks is performed in secondary containment. The loading and unloading areas have been constructed to ensure hoses and piping are located within the containment to prevent exposure. See Figure 3. Except for very large equipment (e.g., cranes) and fixed transformers in Drainage Areas 2 and 3 (SW-002 and SW-003), vehicle and equipment maintenance are performed off-site. On the occasions when fixed transformers or very large equipment require routine maintenance on site, temporary secondary containment is deployed during such maintenance activities.

Chemical Oxygen Demand (COD) Comment 4: Duke Energy requests removal of COD from the monitoring parameters. Duke Energy has established the procedures described above to minimize exposure of chemicals used on site to stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of COD.

Less than the detection limit. Biochemical Oxygen Demand (BOD) Comment 5: Duke Energy requests removal of BOD from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. No industrial processes at the site are expected to be a source of BOD. Duke Energy employs the following practices to minimize exposure to stormwater: Dumpsters that contain general refuse are scheduled for emptying weekly and the lids are closed when not in use. The trash compactor located on site is not open to rainwater and is not expected to contact stormwater. Fertilizer is not applied as part of landscape management. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated BOD was undetectable or detected at levels significantly below the proposed benchmarks. Table 6. Samolina from 2022 Draft Permit Parameter i SW-00300. Benchmark BOD 2.3 mg/I <2.0 mg/13 30 mg/I Note 3. Less than the detection limit. Total Residual Chlorine Comment 6: Duke Energy requests removal of total residual chlorine from the monitoring parameters. Total residual chlorine is monitored under the existing wastewater NPDES permit (NC0039586) at the outfalls requested for ROS. Duke Energy has established the procedures described above to minimize exposure to stormwater as well as the following specific procedures: The chlorine tank in Drainage Area 3 (SW-003) and the loading/unloading area are located within secondary containment which drains back to the process water and is not discharged to the environment. The cooling system employs a dichlorination system. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of total residual chlorine. Table 7. Sam lin from 2022 1 1 Draft Permit Parameter 00 00. Total Residual <0.05 mg/13 <0.05 mg/13 28 ug/I Chlorine Note 3. Less than the detection limit. Comments—Draft NPDES Stormwater Permit NCS000606 Serial: RA-23-0213 Enclosures Fecal Coliform Comment 7: Duke Energy requests removal of fecal coliform from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. While sewage lift stations are located on site, they are operated as part of the wastewater treatment system which operates and is monitored under the existing wastewater NPDES permit (NC0039586). HNP employs robust spill response procedures aimed at ensuring environmental compliance and protection of employees, public health and the environment. Except for operating the wastewater treatment plant, which is permitted separately, no industrial processes are expected to be a source of fecal coliform. Ammonia Nitrogen Comment 8: Duke Energy requests removal of ammonia nitrogen from the monitoring parameters. The ammonia tank in Drainage Area 5 (SW-005) is abandoned and has been closed. Duke Energy is willing to consider re-cleaning the tank to provide appropriate documentation for closure to NC DEQ DEMLR if requested. No active industrial processes at the site are expected to be a source of ammonia nitrogen. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated no detectable levels of ammonia. Table 8. Sam lin from 2022 Parameter Draft Permit jj::���FSV"06 Benchmark Ammonia (NH3 as <0.10 mg/l, <0.10 mg/l, 5.6-15 mg/I N) Note 3. Less than the detection limit. Total Nitrogen Comment 9: Duke Energy requests removal of total nitrogen from the monitoring parameters. HNP is part of a voluntary wildlife sanctuary and has a large existing wildlife (e.g., deer, geese, turkeys, and many others) population on-site, which would be a significant source of this pollutant. Duke Energy employs the following practices to minimize exposure to stormwater: While a nitrogen aboveground storage tank (AST) is located on site, the tank contains nitrogen in a gaseous form used to purge lines. A release from the tank would be to the atmosphere and would not have an impact to stormwater. No industrial processes at the site are expected to be a source of total nitrogen to stormwater runoff. Fertilizer is not applied as part of landscape management. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated total nitrogen was detected significantly below the proposed benchmarks. Table 9.

Draft Permit Total Nitrogen 1.4 mg/I 1.6 mg/I 30 mg/I Comments—Draft NPDES Stormwater Permit NCS000606 Serial: RA-23-0213 Enclosures Total Chromium Comment 10:'Duke Energy requests removal of total chromium from the monitoring parameters. Total chromium is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas ( Table 10). One historic process at the plant used chromium, but that process is no longer active and was conducted inside the main plant building in Drainage Area 6 (SW-006). No active industrial processes are expected to be a source of total chromium and thus has no reasonable potential to be in the industrial stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated total chromium was undetectable or detected at levels significantly below the proposed benchmarks.

Total Nickel Comment 11: Duke Energy requests removal of total nickel from the monitoring parameters. Total nickel is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas ( Table 12). No industrial processes at the site are expected to be a source of total nickel and thus has no reasonable potential to be in the industrial stormwater. Additionally, sampling at SW-003 and SW-006 submitted as part of the permit application indicated nickel was undetectable or detected significantly below the proposed benchmarks. Table 12.

Less than the detection limit. Total Iron Comment 12: Duke Energy requests removal of total iron from the monitoring parameters. Total iron is not a sampling parameter for similar general permits with outdoor materials storage/lay down areas (see Table 14). In 2015, the NC DEQ DWR removed iron from the surface water standards when assessment reports indicated exceedances of the iron criteria in every basin. Evaluations of elevated levels did not correlate with individual dischargers, urban settings nor mining operations. Table 14.

Construction is scheduled to be completed by DATE. Duke Energy is willing to submit a lay down area consolidation plan by March 31, 2024, to facilitate ROS for the remainder of the outfalls. The lay down area consolidation plan would include a proposal for consolidating outdoor storage areas that can be moved and cover of those that cannot. Comment 14: Per discussion with NC DEQ DEMLR on July 27, 2023, if NC DEQ DEMLR does not agree with Duke Energy's assessment to justify removal of total chromium, total nickel, and COD as monitoring parameters after the site visit, Duke Energy is willing to consider sampling for a year (four (4) quarterly samples) to justify removal of these parameters from monitoring if results indicate levels are detected below the proposed benchmarks.

Avery detailed summary of each drainage area was provided in the facility SWPPP. All industrial activities observed onsite correlated with the descriptions in the SWPPP. Materials, waste, chemical storage, etc. descriptions were provided in the application. The areas observed during the inspection appeared to correlate with these summaries as well. Currently the facility does not perform analytical monitoring of the stormwater outfalls. The facility has had representative outfall status under the combined permit. Only two outfalls, Outfalls 3 and 6, have been sampled in the past. Composite sampling equipment is set up at both of the outfalls. The majority of the exterior of the site was observed during the inspection. All accesible stormwater outfalls were viewed as well. In drainage areas 8 and 9 there is a laydown and storage area. Metal piping, sand and gravel, pallets, crushed stone and a few empty tanks were observed in this area. The tanks were reported to be cleaned out by Shamrock Environmental. An old generator is stored in this area and was reported to be removed from the site soon. A second laydown area was observed in drainage areas 1 ad 2. Other materials in the laydown included metal replacement parts and other pieces. There was a small wash bay located in this area. An old container labeled as "Klaraid CPPI 301" has been re-purposed and is used to hold water for the wash bay. Dumpsters with household waste and one paint can were observed in this area. Other dumpsters contained metal materials as well. This area is also used to store equipment. A chemical storage building was observed as well. The firing range was inspected for potential contamination to stormwater. The firing range is birmed on three sides and runnoff is expected to drain internally. The firing range facility has an underground domestic treatment area that handles bathroom and kitchen wastes. The area also houses a single mineral oil transformer. The area is not expected to cause significant stormwater contamination. Stormwater sheetflows from the parking area towards a canal that is an inlet to the site. Water flowing from the canal is treated in the facilities onsite wastewater treatment plant A few good housekeeping practices in the laydown, chemical and equipment storage areas were discussed onsite. Overall, no serious issues were identified during the inspection.

Mentioned in SW app but not in WW permit: • Warehouse • Garage areas • Warehouse • Landfill Laydown—no longer used • Shop laydown • Sandblast/Paint—no longer used • Transformer Yard NCS000606 monitoring Per the NC0039586 permit renewal application, miscellaneous sources of water intermittently discharged to storm drains are: • Heat exchanger on the demineralizer feedwater: It is necessary to heat the source water to the demineralized water treatment system to achieve optimum degassification. To accomplish this, steam is used to heat the feedwater. The condensed steam is discharged to the storm drains that flow to Harris Lake at approximately 5-10 gallons per minute. This steam could contain trace amounts of hydrazine and ammonia used for chemistry control in the auxiliary boiler steam system. Due to the low flow rate and the long retention time, the temperature of the condensed steam should be at ambient temperature upon reaching the lake. • Condenser water box drains: Prior to condenser maintenance or repairs it is sometimes (approximately twice/year) necessary to drain circulating water to the storm drains approximately 60,000 gallons per condenser per event)that discharge to Harris Lake. This water is monitored for selected cooling tower blowdown parameters. • Filtered water storage and Derain water storage tanks: Water is treated using a micro- filtration unit for turbidity control and then stored in a tank prior to subsequent filtration (nano-filtration unit) and disinfection. Occasionally, some water from these tanks may be drained to the storm drains that discharge to Harris Lake. This water may contain trace amounts of chlorine. • Fire protection system: Approximately 5,000 gallons of lake water used for annual testing of the fire protection system is routed to most of the storm drains that discharge to Harris Lake. In the event of a fire, additional water could be discharged to storm drains. • Condenser hotwell: During outages (approximately once per 18 months) it is necessary to drain the condenser hotwell for condenser maintenance and inspection. Approximately 70,000 gallons of this water resulting from condensed steam is drained to storm drains that discharge to Harris Lake. It may contain trace amounts of ethanolamine, 100 ppb or less of boron, and 100 ppb or less ammonia. • Condensate storage tank: Infrequently it is necessary to drain the condensate storage tank for maintenance. Approximately 400,000 gallons per event is drained to storm drains that discharge to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia, and trace hydrazine. eenditioning systems flowrt6 :rt9rm drains te 14affis Lake. The yellme is generally lew a-ad is gr-ea4est in the hi*mid summer-men • Service water system strainers: Infrequently, when service water strainers located at the makeup pumps from the cooling tower basin are backwashed to remove biofouling organisms or debris, a small volume of service water overflows the basin and runs to the adjacent storm drain that discharge to Harris Lake. • Maintenance activities: During maintenance activities at the facility it may become necessary to drain all or some portion thereof of the following plant systems; normal service water, emergency service water, circulating water,potable water, and demineralized water. Maintenance activities at the facility may also require the hydrostatic flushing of system piping with discharge to the storm drain system. In addition, the facility may find it necessary to wash equipment with demineralized water and discharge to the storm drains. 2: Fecal coliform, total nitrogen, total phosphorus, water treatment chemical storage tanks 6: BOD, COD, fecal coliform, total nitrogen,total phosphorus,Various water treatment chemicals Outfalls to group together: 1, 5 2, 6 3 4, SW-B 8, 9 Young, Brianna A From: Safrit, Don <Don.Safrit@duke-energy.com> Sent: Monday, August 14, 2023 11:23 AM To: Young, Brianna A Cc: Wilson, Bob; Annette Lucas; Valentine, Thad Subject: RE: [External] HNP NCS000606 ISW Draft Permit - CAUTION: External email.

See comment 006-18 on map. • Condenser water box drains: Prior to condenser maintenance or repairs it is sometimes (approximately twice/year) necessary to drain circulating water to the storm drains approximately 60,000 gallons per condenser per event) that discharge to Harris Lake. This water is monitored for selected cooling tower blowdown parameters. See comment 002-50, 03-50 on map • Filtered water storage and Demin water storage tanks: Water is treated using a micro-filtration unit for turbidity control and then stored in a tank prior to subsequent filtration(nano-filtration unit) and disinfection. Occasionally, some water from these tanks may be drained to the storm drains that discharge to Harris Lake. This water may contain trace amounts of chlorine. See comment Stormwater 006--Water Treatment Building • Fire protection system: Approximately 5,000 gallons of lake water used for annual testing of the fire protection system is routed to most of the storm drains that discharge to Harris Lake. In the event of a fire, additional water could be discharged to storm drains. Stormwater Outfalls 00100-9 and Drainage Area 010 have fire protection equipment that is tested. • Condenser hotwell: During outages (approximately once per 18 months) it is necessary to drain the condenser hotwell for condenser maintenance and inspection. Approximately 70,000 gallons of this water resulting from condensed steam is drained to storm drains that discharge to Harris Lake. It may contain trace amounts of ethanolamine, 100 ppb or less of boron, and 100 ppb or less ammonia. See comment 002-50, 003-50 on map • Condensate storage tank: Infrequently it is necessary to drain the condensate storage tank for maintenance. Approximately 400,000 gallons per event is drained to storm drains that discharge to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia, and trace hydrazine. See comment 003-43 on map • Air conditioning system condensate: The condensate from various building air conditioning systems flows to various storm drains to Harris Lake. The volume is generally low and is greatest in the humid summer months. Stormwater Outfalls 001-009 and Drainage Area 010 have air conditioning equipment that condensate that sheet flows or is directed to these drains. • Service water system strainers: Infrequently, when service water strainers located at the makeup pumps from the cooling tower basin are backwashed to remove biofouling organisms or debris, a small volume of service water overflows the basin and runs to the adjacent storm drain that discharge to Harris Lake.

Good morning Don, While reviewing the draft permit, a question came up on information provided with permit applications. Per the NCO039586 permit renewal application submitted to the Division of Water Resources (DWR) in 2021, stormwater runoff is composed of laydown yards,training areas, parking lots, roofs, and lawn drainage. Outside storage areas. Flow from these areas is estimated at 8.8 million gallons per month, based on average rainfall of 43 inches per 5 year and a runoff assumption factor of 0.7. Per the NCO039586 permit renewal application, miscellaneous sources of water intermittently discharged to storm drains are: • Heat exchanger on the demineralizer feedwater: It is necessary to heat the source water to the demineralized water treatment system to achieve optimum degassification. To accomplish this, steam is used to heat the feedwater. The condensed steam is discharged to the storm drains that flow to Harris Lake at approximately 5-10 gallons per minute. This steam could contain trace amounts of hydrazine and ammonia used for chemistry control in the auxiliary boiler steam system. Due to the low flow rate and the long retention time,the temperature of the condensed steam should be at ambient temperature upon reaching the lake. • Condenser water box drains: Prior to condenser maintenance or repairs it is sometimes (approximately twice/year) necessary to drain circulating water to the storm drains approximately 60,000 gallons per condenser per event) that discharge to Harris Lake. This water is monitored for selected cooling tower blowdown parameters. • Filtered water storage and Demin water storage tanks: Water is treated using a micro-filtration unit for turbidity control and then stored in a tank prior to subsequent filtration(nano-filtration unit) and disinfection. Occasionally, some water from these tanks may be drained to the storm drains that discharge to Harris Lake. This water may contain trace amounts of chlorine. • Fire protection system: Approximately 5,000 gallons of lake water used for annual testing of the fire protection system is routed to most of the storm drains that discharge to Harris Lake. In the event of a fire, additional water could be discharged to storm drains. • Condenser hotwell: During outages (approximately once per 18 months) it is necessary to drain the condenser hotwell for condenser maintenance and inspection. Approximately 70,000 gallons of this water resulting from condensed steam is drained to storm drains that discharge to Harris Lake. It may contain trace amounts of ethanolamine, 100 ppb or less of boron, and 100 ppb or less ammonia. • Condensate storage tank: Infrequently it is necessary to drain the condensate storage tank for maintenance. Approximately 400,000 gallons per event is drained to storm drains that discharge to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia, and trace hydrazine. • Air conditioning system condensate: The condensate from various building air conditioning systems flows to various storm drains to Harris Lake. The volume is generally low and is greatest in the humid summer months. • Service water system strainers: Infrequently, when service water strainers located at the makeup pumps from the cooling tower basin are backwashed to remove biofouling organisms or debris, a small volume of service water overflows the basin and runs to the adjacent storm drain that discharge to Harris Lake. • Maintenance activities: During maintenance activities at the facility it may become necessary to drain all or some portion thereof of the following plant systems: normal service water, emergency service water, circulating water,potable water, and demineralized water. Maintenance activities at the facility may also require the hydrostatic flushing of system piping with discharge to the storm drain system. In addition, the facility may find it necessary to wash equipment with demineralized water and discharge to the storm drains. Do any of these sources flow to stormwater outfalls, and if so, which one(s)?

The permit authorizes the permittee to discharge storm water from the station in accordance with the discharge limitations, monitoring requirements and other conditions set forth in the permit. The permit number is NCS0039586 and expires on August 31, 2021. 1.2 SWPPP Development The permit requires the permittee to develop and implement a Storm Water Pollution Prevention Plan (SWPPP)for the station. The SWPPP is a comprehensive site-specific plan which details measures and practices at the station to reduce and/or eliminate storm water pollution and is based on an evaluation of the pollution potential of the site. The body of this document focuses on development of the SWPPP and the framework of permit compliance which will likely remain unchanged throughout the permit cycle. Where significant changes do occur to the content of the body of the SWPPP, the plan will be amended as required by the permit conditions. The body of the SWPPP is developed to sequentially and specifically address the requirements of Part I of the permit and provides references to the subsections of the permit. Due to the fluid nature of implementing a SWPPP for a complex site such as the Harris Nuclear Plant, the detailed content and documentation of the frequent plan responsibilities are compiled in the appendices. The series of appendices includes SWPPP content in more concise formats such as fact sheets, tables, forms, data, and procedures which can be easily amended for site changes or completed for demonstration of compliance. The appendices may grow in content through the permit cycle as the SWPPP evolves to adapt to changing site conditions and operations. In addition, the Harris Nuclear Plant may utilize company software and databases to ensure the scheduling, completion, and documentation of SWPPP requirements. E-Track is an event management database system used to schedule deadlines for reoccurring events such as inspections, monitoring, and annual updates or record significant events, such as reportable spills. The system provides for ownership of tasks, assignment of staff, electronic notification, and simple documentation of event completion. It may be used to the extent it aids in the implementation of the SWPPP and therefore be a repository of permit compliance. To the extent possible, output from the system will be compiled for archival in the SWPPP. Another database system, Consolidated Access Suite (CAS), may be utilized in conjunction with E-Track to document station operations that demonstrate compliance with the permit requirements. Typically, this system is used to direct maintenance and operational tasks for the purposes of sustaining power generation thereby limiting failures in service and equipment that may Page 3 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 otherwise contribute to storm water contamination or unauthorized discharges. These systems will be periodically referenced for their use in scheduling implementation and documenting compliance. 1.3 Management Certification "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to ensure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." Name: John R. Dills Signature: Date: Page 4 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 2.0 Storm Water Pollution Prevention Plan 2.1 Site Overview 2.1.1 General Location Map NPDES Permit Reference: Part 1, Section A 21.2a(1) A general location map of the facility is provided in Appendix A. The facility address is 5413 Shearon Harris Road, New Hill, NC 27562. 2.1.2 Narrative Description NPDES Permit Reference: Part 1, Section A 21.2a(2) The Harris Nuclear Plant is an electric generating station located on Shearon Harris Reservoir in the southwestern region of Wake County, North Carolina. The plant is located near the community of New Hill, and approximately 22 miles southwest of Raleigh, North Carolina. The plant property is comprised of approximately 8,351 acres. The plant is owned and operated by Duke Energy Progress, LLC. The Harris Nuclear Plant began commercial operation on May 2, 1987, and consists of one 1039 MW (gross) pressurized water nuclear reactor unit and associated support facilities. Primary structures contiguous with the reactor unit containment include a reactor auxiliary building, a turbine building, a fuel handling building, an operations building, and a waste processing building. Separate structures include a security building, an administration building, a cooling tower, a service building, various warehouses, a chemical storage building, a diesel generator building, a water treatment building, diesel fuel storage tanks, numerous transformers, an electrical switchyard, a security firing range and other support facilities. Service water and make-up water needed to replace cooling water lost through evaporation is withdrawn into the plant through the Make-Up Intake Structure. The intake structure is located at the end of a canal connected to the main body of Shearon Harris Reservoir southeast of the plant. Emergency service water for the plant is withdrawn from the Emergency Service Water Intake Channel. This channel is connected to the upper Auxiliary Reservoir located west of the plant. Emergency service water is discharged through a canal back into the upper Auxiliary Reservoir. Both intake canals and the discharge canal are designated as waters of the United States. Page 5 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 The industrial use area of the plant is comprised of twelve storm water drainage areas. Ground cover at the facility is comprised of a combination of building roofs, paved access roads and parking areas, gravel-surfaced areas, and grassed and wooded areas. Approximately 16% of the total industrial use area of the facility is impervious. Drainage area delineations and outfall locations are indicated on the site map in Appendix A. Summary sheets for each storm water outfall, including description of the outfall, description of the contributing drainage area, significant materials and activities, and best management practices (BMPs) are provided in Appendix B. The plant has five internal wastewater outfalls and one combined, external wastewater outfall. A summary table of the NPDES permitted wastewater outfalls is provided in Appendix C. All storm water runoff from the plant enters the adjoining Shearon Harris Reservoir. The reservoir has a full pond elevation of 220 feet above mean sea level. The reservoir spillway discharges into Buckhorn Creek and subsequently into the Cape Fear River approximately 2 miles to the south. In addition to the significant materials particular to each drainage basin, herbicides are applied to selected areas throughout the plant to eliminate undesirable vegetation. All herbicides used at the facility are approved by the company and considered safe to the environment when used according to directions. Records are retained by the vendor and at the plant documenting areas treated, specific herbicides used, and application quantities. 2.1.3 Site Map NPDES Permit Reference: Part 1, Section A 21.2a(3) A site map of the facility is provided In Appendix A. 2.1.4 Significant Spills and Leaks NPDES Permit Reference: Part 1, Section A 21.2a(4) All spills or leaks including but not limited to, releases of oil or hazardous substances in excess of reportable quantities under section 311 of the Clean Water Act (40 CFR 110.3 and 40 CFR 117.3) or section 102 of CERCLA (40 CFR 302.4) are documented by the Site Environmental Coordinator(s). The Site Environmental Coordinator(s) records the details of the spill and any corrective actions taken to mitigate spill impacts. All environmental incidences at the plant are stored for review in the station's Corrective Action System (CAS) or similar record retention system. The Site Environmental Coordinator(s) shall update the list of significant spills and leaks for the previous three years by May 31 of every permit year and place a copy in Appendix D of this plan. Page 6 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 2.1.5 Non-Storm Water Discharge Certification NPDES Permit Reference: Part 1, Section A 21.2a(5) An evaluation for non-storm water discharges shall be performed annually by the Site Environmental Coordinator(s). The evaluation shall determine if a non-storm water discharge is present or otherwise how that discharge is permitted or otherwise authorized. Supporting evaluation information and a copy of the certification shall be included in Appendix E. Allowable non-storm water discharges include: • Foundation drains and natural springs; • Flows from riparian habitats and wetlands; • Air conditioner condensate that includes no added chemicals; • Waterline and fire hydrant flushing; • Discharging from fire-fighting, fire-fighting training, and fire system testing; • All other discharges authorized by an NPDES permit. 2.2 Storm Water Management Strategy 2.2.1 Feasibility Study NPDES Permit Reference: Part 1, Section A 21.2b(1) This section provides a review of the technical feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and processes to rainfall and storm water runoff. Below are descriptions of the existing operations at the plant that present the potential for negative impacts to storm water runoff. These descriptions demonstrate the current practices in use to prevent exposure of storage areas, material handling operations and fueling operations. Page 7 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 DIESEL FUEL AND GASOLINE STORAGE Diesel fuel and gasoline is stored at the plant in several different tanks and containers at the plant. The diesel fuel is primarily used as fuel for emergency diesel generators at the plant. The diesel fuel and gasoline is used to fuel plant vehicles and miscellaneous equipment. The largest containers at the plant are two 175,000 gallon underground diesel fuel storage tanks located north of the plant, and two 110,000 gallon field-erected aboveground diesel fuel storage tanks located in the southwestern area of the plant yard. The aboveground tanks are located within a single common concrete secondary containment structure equipped with a closed drain valve. Drainage from the containment discharges into the plant 10,000 gallon capacity Oil/Water Separator. The plant contains eight additional aboveground diesel fuel tanks, one aboveground gasoline tank, and numerous 55 gallon petroleum storage drums. The remaining tanks are small, shop-fabricated steel tanks maintained at various locations around the plant. The plant contains one 1,000 gallon underground diesel fuel storage tank at the Security Building, and one 10,000 gallon underground diesel fuel storage tank and one 10,000 gallon underground gasoline storage tank in the Mobile Equipment Area. The plant also maintains one small diesel fuel tank and one small gasoline tank on a mobile fuel truck. A complete listing of these containers, including inspection and testing requirements, secondary containment descriptions and inspection requirements, and tanker unloading operation requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All diesel fuel and gasoline storage tanks are provided with some means of passive secondary containment or are integral double-walled containers as described in detail in the Harris Nuclear Plant SPCC Plan. All external containments are inspected prior to being manually drained in accordance with the SPCC Plan. Secondary containments either drain into the plant 10,000 gallon capacity Oil/Water Separator, or onto the plant yard. Mobile tanks are stored in areas that drain to the Oil/Water Separator while in standby mode. Refueling operations for all diesel fuel and gasoline containers are conducted in constant attendance in accordance with plant procedures and the Harris Nuclear Plant SPCC Plan. Tanker trucks are brought on-site to refill the two 175,000 gallon underground diesel fuel storage tanks and the two aboveground 110,000 gallon diesel fuel storage tanks. Tanker unloading into the two 175,000 gallon underground storage tanks, and into the two 110,000 gallon aboveground storage tanks, is conducted on a concrete containment pad adjacent to the tanks. The containment is equipped with open drains to the Oil/Water Separator. Tanker trucks are also brought on-site to refill the other aboveground and underground diesel fuel and gasoline tanks. These tankers unloading operations are conducted adjacent to the containers and in constant attendance in accordance with plant procedures. Prior to filling any container, tank levels are verified by electronic high-level and low-level annunciators, visual sight glasses, or are otherwise verified as described in the plant SPCC Plan. Page 8 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 The plant contains diesel fuel piping primarily associated with the delivery of diesel fuel from the two 110,000 gallon aboveground diesel fuel storage tanks to the emergency diesel generator system, and to other locations and systems. The piping is located aboveground or within concrete trenches. None of this piping is in contact with the soil. Portions of this piping are located within the secondary containment structure surrounding the tanks or at the fuel forwarding skid within the containment pad for the tanker unloading station. All aboveground piping outside of these concrete containments, and all piping within the concrete trenches, is provided secondary containment by open drains to the Oil/Water Separator. Diesel fuel transfer operations from the tanks to the emergency diesel generator system is an automated process. Facility operations personnel conduct daily routine facility walk-downs to observe all aboveground piping, valves, expansion joints, flange joints, and structural supports. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with diesel fuel and gasoline storage practices or tanker unloading operations at the facility. All diesel fuel and gasoline containers are in compliance with the plant SPCC Plan. USED OIL STORAGE AND HANDLING Used oil is collected and stored in eleven small tanks and containers at the plant. The largest used oil tanks are one 4,000 gallon steel tank and one 2,000 steel gallon tank in the Mobile Equipment Area. These two tanks are within a common concrete containment structure. There is a 1,000 gallon steel used oil tank adjacent to the Oil/Water Separator that collects used oil removed by the separator. This tank is within the same concrete containment pad as the separator. There is a 1,000 gallon steel used oil tank adjacent to the Emergency Diesel Generator Building and within a concrete containment structure. There are three 220 gallon poly used oil containers at the plant. Two of these containers are within a common metal containment bin on a covered concrete pad at the Paint Shop. The remaining container is within a concrete containment structure in the Mobile Equipment Area. The plant has a 1,000 gallon steel used oil tank mounted on a mobile trailer. While in standby mode the trailer is maintained in an area of the plant with yard drains that discharge into the Oil/Water Separator. There is a 100 gallon hydrogen seal oil drain tank within a concrete containment structure adjacent to the Turbine Building, and a 200 gallon oil filter drain tank inside the Mobile Equipment Building. The plant also maintains two 55 gallon used cooking oil drums maintained within a poly containment shelter at the east end of the Service Building. A complete listing of all used oil tanks, including inspection and testing requirements, secondary containment descriptions and inspection requirements, and tanker loading operation requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All external containments are inspected and manually drained in accordance with the SPCC Plan. Secondary containments either drain into the plant 10,000 gallon capacity Oil/Water Separator, or onto the plant yard. Mobile tanks are stored in areas that drain to the Oil/Water Separator while in standby mode. Tanker trucks are brought on-site to load used oil as needed from the Page 9 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 various used oil tanks. The tanker loading operations are conducted adjacent to the containers and in constant attendance in accordance with plant procedures. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with used oil storage practices or tanker loading operations at the facility. All used oil containers are in compliance with the plant SPCC Plan. LUBE OIL STORAGE The plant has three lube oil storage tanks consisting of one 14,000 gallon Turbine Generator Batch Oil Tank and two 1,500 gallon Turbine Lube Oil Sump Tanks. All three tanks are located within concrete containment basins inside the Turbine Building. The inspection and testing requirements for these lube oil tanks is described in detail in the Harris Nuclear Plant SPCC Plan. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with these lube oil tanks. OIL-FILLED EQUIPMENT AND SYSTEMS Oil-filled equipment and systems at the plant includes lubrication oils, mineral oils and hydraulic oils maintained within closed conduit systems. These oils are used in hydraulic systems, lubricating systems, gear boxes, machining coolant systems, heat transfer systems, transformers and circuit breakers. Oil-filled equipment and systems, including container inspection requirements and secondary containment descriptions and inspection requirements, are described in detail in the Harris Nuclear Plant SPCC Plan. The plant contains four lube oil and hydraulic oil reservoir systems located inside the Turbine Building. These reservoir systems are not exposed to storm water. Any oil release occurring from these systems will enter open floor drains that discharge into the plant Oil/Water Separator. The largest oil-filled equipment containers exposed to storm water are large transformers containing mineral oil and located in the Transformer Yard on the east side of the Turbine Building. This equipment consists of three 9,180 gallon Start-Up Transformers, four 7,780 gallon Main Step-Up Transformers, and two 5,500 gallon Auxiliary Transformers. All of these transformers are within a concrete containment sump equipped with a manually operated dewatering pump. Containment contents are inspected in accordance with the plant SPCC Plan prior to dewatering, and sump contents are pumped to the plant Oil/Water Separator. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the large transformers. Smaller oil-filled equipment containers exposed to storm water include numerous pad-mounted service transformers containing mineral oil located at various locations around the plant. These Page 10 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 transformers are used to provide power to the various buildings and facilities at the plant, and are generally not provided with any means of passive secondary containment. Any mineral oil release occurring from these service transformers would result in failure of the unit and subsequent loss of power. The plant relies on system monitoring, frequent inspections, preventative maintenance, and active containment measures as described in the plant SPCC Plan to contain any potential release occurring from these transformers. A mineral oil release from these units will typically discharge vertically into the underlying conduit penetrations which will provide some degree of containment. The potential for storm water impacts associated with mineral oil releases from any of these uncontained pad-mounted transformers is minimal, and could be reduced by the installation of dedicated secondary containments with manually operated drain valves or open drains to the Oil/Water Separator. CHEMICAL STORAGE AND HANDLING Various chemicals are used at the plant for water treatment and other purposes. Bulk chemicals are delivered by tanker trucks and unloaded into respective storage tanks at designated locations. Smaller chemical containers and drums are delivered to the receiving area of Warehouse 9 for storage or subsequent transport via company vehicles to the Water Treatment Building, Paint Shop, Bulk Warehouse, Chemical Warehouse, the Sewage Treatment Plant, and other locations. Plant personnel are trained in safe forklift usage, safe handling of chemicals, and proper use of spill containment and cleanup materials. Spill kits are located at receiving areas. Two 5,500 gallon sodium hypochlorite tanks, one 5,600 gallon phosphoric acid tank, three 4,500 gallon water treatment chemical storage tanks and other smaller chemical containers are used for water treatment and analysis purposes at the Cooling Tower. The sodium hypochlorite tank and other small tanks and containers are within a concrete containment. The containment can be drained to the yard drainage system or can be pumped into the Cooling Tower basin. Small containers of chemicals used for analysis are stored inside the chemical storage building. Four bulk chemical storage tanks, consisting of a 10,800 gallon caustic tank, a 7,500 gallon sulfuric acid tank, a 1,500 gallon empty ammonia tank, and a liquid nitrogen to gaseous nitrogen tank are located at the south end of the Turbine Building. These tanks are within containments that can be drained to the yard drainage system or to a sump that discharges to the Oil/Water Separator. An 8,315 gallon sulfuric acid storage tank is located at the east end of the Water Treatment Building. This tank is within a concrete containment with an open drain to a sump that pumps to the Neutralization Basin. Sodium carbonate, sodium hypochlorite, sodium hydroxide, and water treatment polymers are stored in tanks and containers at the Sewage Treatment Plant. Some of these tanks and containers are stored in totes inside metal buildings with built-in sumps. All chemical storage tanks and containers are provided with some means of containment consisting of secondary containment structures with manually operated drain valves, secondary Page 11 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 containment structures with open drains to other containment or treatment systems, or are stored inside buildings. All external containments with drain valves are inspected prior to being manually draining. All chemical deliveries are conducted adjacent to the containers or at receiving areas in constant attendance and in accordance with plant procedures. Chemical container levels are verified prior to initiating any tanker unloading operation. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the storage and handling of chemicals. WASTE HANDLING AND STORAGE Waste chemicals and oils produced inside the protected area of the plant is typically transported to and processed in the chemical processing area of the Paint Shop. These materials are stored within a covered concrete containment area with open drains to the Oil/Water Separator. Waste chemicals produced outside the protected area of the plant are typically transported to, processed and stored in Warehouse 6. Waste oils produced outside the protected area of the plant are typically transported to the used oil tanks in the Mobile Equipment Area. Hazardous materials are accumulated in designated satellite waste storage areas at the plant. All satellite accumulation areas are either under shelters or are inside buildings. All hazardous waste generated at the plant is eventually transported to and stored in the Central Hazardous Waste Storage Area located under a shelter attached to the Chemical Warehouse. Dumpsters and roll-off containers are used at certain locations to collect inert materials and solid waste for disposal. No liquids or other materials that could potentially impact storm water are disposed of in external dumpsters. Two closed trash compactors are located west of the Chemical Warehouse. Recyclable waste materials are collected in covered storage containers at several locations inside buildings. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with waste handling and storage. EXTERNAL STORAGE, LAYDOWN AND PARKING AREAS Inert materials such as miscellaneous wood, structural steel, cable, empty drums and other metal components are stored at various external laydown yard areas at the plant. These laydown areas are typically paved or gravel-surfaced. No liquids or materials that could potentially impact storm water are stored on external laydown areas. Cranes and other mobile equipment are parked on the crane laydown yard and in other external parking and storage areas. This equipment can contain oils, fuels, hydraulic fluids and other materials that represent potential storm water impacts. Plant employees are trained to promptly report and respond to spills. Page 12 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Other materials such as soil, sand, gravel, compost, concrete and asphalt may be stockpiled at certain locations on a temporary basis until the material can be recycled, reused or properly disposed of off-site. Stockpiled materials such as soil that could potentially result in the mobilization of sediments when exposed to rainfall are covered, stabilized by temporary or permanent seeding or are otherwise provided with necessary sediment control measures. Drainage areas containing external storage, laydown and parking areas are described in Appendix B. The potential for storm water impacts associated with these external areas could be reduced by covering materials such as soil, gravel, treated lumber, flaking painted surfaces and other materials that represent the greatest potential for such impacts, by regular inspections and maintenance of mobile equipment, and by maintaining mobile equipment inside temporary containments while parked. Constructing permanent shelters over these external areas to prevent contact with storm water is cost prohibitive. SECURITY TRAINING AND FIRING RANGE The plant maintains a designated facility for security training purposes that includes an external firing range. The range is located west of the plant on the north side of the Emergency Service Water Intake Canal. Lead-based ammunition is routinely fired into bullet traps at the range. Storm water runoff from this area flows south and southwest overland into the adjoining Emergency Service Water Intake Canal. The embankment soil pH is routinely monitored and maintained within a range to prevent the lead from becoming soluble. Security personnel maintain an inventory of expended rounds fired and routinely harvesting lead from bullet traps or the soil. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the security training and firing range. Constructing permanent shelters over the firing range to eliminate exposure to rainfall is cost prohibitive. Duke Energy continuously pursues strategies to holistically manage the exposure of storm water to power generation, waste disposal, and facility management operations. These efforts consider the technical and economic feasibility of changing the methods of operations and/or storage practices. The details from the planning, design, and construction of such improvements shall be incorporated into the SWPPP upon completion. Page 13 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 2.2.2 Secondary Containment Requirements and Records NPDES Permit Reference: Part 1, Section A 21.2b(2) The plant manages numerous oil-based liquids and non-oil based liquids and chemicals which are critical to power generation and transmission, water treatment, waste handling and treatment, and operation of vehicles and equipment. The Harris Nuclear Plant is subject to the requirements of U.S. Environmental Protection Agency (EPA) Oil Pollution Prevention Regulation 40 CFR Part 112 because the oil storage capacity at the facility exceeds 1,320 gallons and the proximity to waters of the United States. As a result, the facility maintains a Spill Prevention, Control, and Countermeasures (SPCC) Plan pursuant to, 40 CFR Part 112. This plan addresses secondary containment, inspections and record keeping requirements for all oil containers of 55 gallon capacity and greater. A copy of the SPCC is not included in the SWPPP as the document is actively managed at all times for evolving site conditions; however, a current version is maintained in the Nuclear Fusion document data base and a version with mark-ups is maintained in the office of the Site Environmental Coordinator(s) and referenced herein. Pursuant to this section of the permit, secondary containment is required for the bulk storage of liquid materials, storage in any amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, and storage in any amount of hazardous substances, in order to prevent spills and leaks from contaminating storm water runoff. Secondary containments shall be sized to contain the full capacity of the single largest container within the containment structure. Secondary containments exposed to precipitation shall also have additional capacity to contain the 25-year, 24-hour storm event. This additional capacity requirement shall take into consideration any storm water runoff entering the containment structure from upland areas if applicable. Secondary containments draining into storm water conveyance systems or onto the ground surface shall be equipped with manually- operated, lockable or otherwise secured drain valves or dewatering pumps. Flapper-type valves shall not be used. Accumulated storm water within secondary containments shall be visually inspected for color, foam, outfall staining, presence of sheen, oils or chemicals prior to release in accordance with the frequencies specified in the plant SPCC Plan. Inspections will include observation for leaks, condition of containment, valve drain closure and locking, and presence of excessive debris and sediment. Inspection records shall be maintained at the facility. Exterior containments exposed to precipitation shall be inspected promptly after any significant rainfall event, and collected water within containments shall be drained to maintain adequate spill storage capacity within the containment. A list of all liquids and chemicals and their associated secondary containment provisions are provided in Appendix F. Documentation for periodic inspections for leaks and recordation of accumulated storm water releases shall be placed in Appendix I. Page 14 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 2.2.3 Best Management Practices (BMPs) Summary NPDES Permit Reference: Part 1, Section A 21.2b(3) A number of best management practices are currently in place at the station. These BMPs were instituted over a number of years as a result of various regulatory drivers and good housekeeping objectives. While a chosen practice provides some level of pollution prevention as it relates to the management of storm water discharges under this permit, the historic rationale behind implementing such a practice is comprehensive of a number of contributing factors. To document the ongoing implementation of these practices as part of the SWPPP, Table 2 from the Industrial Storm Water Fact Sheet for Steam Electric Power Generating Facilities (EPA-833-F-06-030) was reviewed and evaluated, and is provided in Appendix O. A high-level review of the BMPs is provided below along with a rationale for implementation. The detailed listing of these BMPs for each drainage area is provided in the outfall descriptions in Appendix B where information regarding the industrial activities and significant sources of pollutants are also compiled. The compiled information in the appendix captures an ongoing assessment process for BMP selection and implementation. The Site Environmental Coordinator(s) shall rely on Table 2 from EPA-833-F-06-030 for the improvement, installation and implementation of BMPs to address data collected through monitoring of storm water discharges. The Site Environmental Coordinator(s) may also rely on other sources of information to develop and implement appropriate BMPs not specifically listed in Table 2. This list of BMPs shall be reviewed and updated annually as new practices are incorporated in the plan or warranted as a result of exceedances of analytical monitoring benchmarks detailed in the permit. FUGITIVE DUST EMISSIONS The potential for fugitive dust to impact storm water runoff drives the need for emission management practices. The station maintains an air permit with NCDEQ that includes the control of fugitive dust emissions as a programmatic requirement. Fugitive dust emissions are managed as necessary through a variety of BMPs that include restricting frequent traffic to paved roadways, periodic wetting of haul roads, and permanent stabilization of dust generating surfaces. Fugitive dust control is typically a contractual requirement of any contractors brought on-site to perform services that may involve the creation of fugitive dust. Fugitive dust generation is typically insignificant at the facility. LOADING AND UNLOADING OF FUELS, OILS AND NON-OIL LIQUIDS AND CHEMICALS The plant maintains numerous locations for the loading and unloading of fuels, oils and non-oil liquids and chemicals. The potential for spills and leaks to release to storm drains or overland drainage pathways to receiving waters presents a source of unauthorized discharges and potential storm water contamination. Loading and unloading operations follow plant procedures, the requirements specified in the plant SPCC Plan, and the requirements specified in the DOT unloading/loading procedures 49 CFR Part 177, Subpart B. Page 15 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 BMPs utilized during loading and unloading operations include constant attendance by qualified plant personnel, appropriate training, verification of container levels prior to filling, and the close proximity of appropriate spill response materials and resources. BMPs also include dedicated containment platforms for tanker unloading of diesel fuel into the two 175,000 gallon underground diesel fuel storage tanks and into the two 110,000 gallon field-erected aboveground diesel fuel storage tanks. Lined concrete containments are utilized for unloading of high usage chemicals. Temporary containments are used for the unloading and delivery of other fuels and chemicals. ABOVEGROUND LIQUID STORAGE TANKS AND PIPING The plant maintains numerous aboveground storage tanks for fuels, oils and non-oil liquids and chemicals. Aboveground piping is present at certain locations, and is primarily associated with the transfer of diesel fuel for operation of emergency diesel generators and other equipment. The potential for spills and leaks to release to storm drains or overland drainage pathways to receiving waters exists, and presents a source for an unauthorized discharge and contamination of storm water. The plant relies on a variety of BMPs to reduce the potential for leaks or spills to impact storm water. BMPs utilized for the larger bulk storage tanks include either dedicated secondary containments with secured, manually-operated drain valves or pumps, dedicated secondary containments equipped with open drains to the Oil/Water Separator. BMPs utilized for smaller containers and drums include maintaining the containers inside various buildings, on spill pallets or within containment shelters. BMPs utilized for aboveground piping includes concrete containments and open drains that discharge into the Oil/Water Separator. Additional BMPs utilized include bollards and barriers to prevent vehicular impacts, tank level indicators to prevent overfilling and detect leaks, routine inspections and maintenance of tanks, piping, valves and connections. Routine inspection and integrity testing requirements for bulk oil tanks are specified in the plant SPCC Plan. OIL-FILLED EQUIPMENT AND SYSTEMS The plant maintains oil-filled electrical equipment at numerous locations. The potential for spills and leaks to release to storm drains or overland drainage pathways to receiving waters exists, and presents a source for an unauthorized discharge and contamination of storm water. The plant relies on a variety of BMPs to reduce the potential for leaks or spills from this equipment to impact storm water. The plant utilizes a concrete containment sump equipped with a manually operated dewatering pump for the large transformers in the Transformer Yard on the east side of the Turbine Building. Containment contents are inspected in accordance with the plant SPCC Plan prior to dewatering, and sump contents are pumped to the plant Oil/Water Separator. BMPs utilized for the numerous uncontained pad-mounted service transformers at the plant includes system monitoring to detect any adverse conditions associated with the equipment, daily rounds, and routine inspections performed in accordance with the requirements specified in the plant SPCC Plan. Page 16 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 WASTE HANDLING AND STORAGE Waste chemicals, used oils and waste products are produced, handled, processed and characterized at various locations at the plant. Wastes produced inside the protected area of the plant is typically transported to and processed in the chemical processing area of the Paint Shop. Waste chemicals produced outside the protected area of the plant are typically transported to, processed and stored in and near Warehouse 6. Waste oils produced outside the protected area of the plant are typically transported to the used oil tanks in the Mobile Equipment Area. Hazardous materials are accumulated in designated satellite waste storage areas at the plant, and all hazardous waste generated at the plant is eventually transported to and stored in the Central Hazardous Waste Storage Area at the Chemical Warehouse and at Warehouse 6. Dumpsters and roll-off containers are used at certain locations to collect inert materials and solid waste for disposal. Recyclable waste materials are collected in covered storage containers at several locations inside buildings. The potential for spills and leaks from waste materials to release to storm drains or overland drainage pathways to receiving waters exists, and presents a source for an unauthorized discharge and contamination of storm water. The plant relies on a variety of BMPs to reduce the potential for impacts to storm water associated with waste handling and storage. BMPs utilized include maintaining all satellite accumulation areas under shelters or inside buildings, storing waste materials at the Paint Shop within a covered concrete containment area with open drains to the Oil/Water Separator, and storing hazardous wastes under shelter at the Central Hazardous Waste Storage Area. BMPs utilized for trash collection include disallowing the disposal of liquids or other materials that could potentially impact storm water in dumpsters and roll-off containers, and maintaining dumpsters closed. EXTERNAL STORAGE, LAYDOWN AND PARKING AREAS Inert materials such as miscellaneous wood, structural steel, cable, empty drums and other metal components are stored at various external laydown yard areas at the plant. Cranes and other mobile equipment are parked on the crane laydown yard and in other external parking and storage areas. Other materials such as soil, sand, gravel, compost, concrete and asphalt may be stockpiled at certain locations on a temporary basis until the material can be recycled, reused or properly disposed of off-site. The potential for impacts to storm drains or overland drainage pathways to receiving waters exists, and presents a source for an unauthorized discharge and contamination of storm water. The plant relies on a variety of BMPs to reduce the potential for impacts to storm water from these external areas. BMPs utilized include disallowing the storage or disposal of liquids or other materials in external areas, stabilizing and/or covering of stockpiled soils and other materials that could be mobilized by storm water, frequent inspections of these areas, and prompt reporting and response to spills. Page 17 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 VEHICLE AND EQUIPMENT MAINTENANCE The plant maintains a garage facility for maintenance of plant vehicles and equipment located southeast of the Chemical Warehouse outside of the protected area. Vehicles and equipment have the potential to leak or spill fuel, hydraulic fluids and oils if not properly maintained. Maintenance is performed on a routine basis to keep vehicles and equipment in good operational condition to reduce the potential for spills and leaks. Some maintenance may be performed offsite at licensed commercial facilities. BMPs utilized include performing all maintenance inside the Garage, utilizing temporary containments for the capture of fluids, and proper labeling, handling and disposal of used materials, parts and fluids. BMPs also include readily available spill response materials. Storm water runoff from the Garage and surrounding area enters a drainage channel that flows southeasterly, eventually into the Intake Canal. SECURITY TRAINING AND FIRING RANGE The plant maintains a designated facility for security training purposes that includes an external firing range. Lead-based ammunition is routinely fired into earthen embankments at the range. The potential for mobilization of sediments containing lead exists, and presents a source for an unauthorized discharge and contamination of storm water. Storm water runoff from this area flows overland into the Emergency Service Water Intake Canal. BMPs utilized include tracking the amount of ammunition fired into the embankments, routine monitoring and adjustment of soil pH levels to prevent the lead from becoming soluble, and routine harvesting of lead from the soil per EPA guidance for firing range BMPs. A list of all currently utilized BMPs within the contributing drainage area for each storm water outfall is provided on the fact sheets in Appendix B. 2.3 Spill Prevention and Response Procedure NPDES Permit Reference: Part 1, Section A 21.2c The station maintains a storm water compliance program to control and minimize contamination of storm water resulting from spills and exposure to materials associated with facility operations. This procedure incorporates an assessment of potential pollutant sources based on a materials inventory of the plant. The materials inventory is primarily compiled and maintained through two efforts; first for development and compliance with the plant SPCC Plan, and secondly for the management of hazardous materials. The Harris Nuclear Plant is required to develop and maintain an SPCC Plan in accordance with 40 CFR Part 112 because the oil storage capacity at the facility exceeds 1,320 gallons and the proximity to waters of the United States. The SPCC Plan provides an assessment of spill potential, measures for spill prevention, and a spill response protocol for oil-based liquids. A similar approach has been adopted for non-oil based liquids and chemicals representing the balance of materials at the plant. However, the plant will likely maintain the same general spill response protocol from the SPCC Plan regardless of the types of materials except where Page 18 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 hazardous materials regulations and notifications deviate from SPCC requirements. This is recognized in the response procedures. The Site Environmental Coordinator(s) use included maps for all oils, liquids, chemicals and materials that have the potential to impact storm water. The Site Environmental Coordinator(s) shall routinely review site procedures and practices for applicability with current plant operations and practices, shall amend/update requirements as necessary, and shall communicate changes to responsible plant personnel. A responsible person shall be on-site at all times during facility operations that have increased potential to contaminate storm water runoff through spills or exposure of materials associated with facility operations. The plant maintains an Emergency Response Organization (ERO) consisting of personnel from all areas of the plant. In the event of an incident, the on-duty Operations Shift Manager (OSM), or other qualified Operations response persons, will assume responsibility as the Emergency Coordinator. The Emergency Coordinator is responsible for contacting appropriate emergency response personnel, the SPCC Coordinator, and the Hazmat Team. The Emergency Coordinator will also assume responsibility as the Incident Commander until such time that the Hazmat Team mobilizes to the incident. The on-site Fire Brigade Team is also trained in spill response. Spill Prevention and Response Procedures at the Harris Nuclear Plant are listed in Appendix G. 2.4 Preventative Maintenance and Good Housekeeping Program NPDES Permit Reference: Part 1, Section A 21.2d Plant personnel perform a number of various inspections and tasks for operational and regulatory purposes that constitute a Preventative Maintenance and Good Housekeeping Program. These efforts cover plant areas such as the Reactor, Turbine, and Diesel Generator Buildings and surrounding support facilities, tanks and equipment within and outside the protected area; waste handling and storage areas, water and wastewater treatment areas, the Security Training Facility, and external laydown, storage and parking areas. In accordance with the permit, the preventative maintenance and good housekeeping program shall include all features of the storm water drainage system at the facility. The Site Environmental Coordinator(s) shall ensure the Preventative Maintenance and Good Housekeeping Program is being implemented either through self-performance or review of delegated tasks. The Site Environmental Coordinator(s) shall record compliance of the program either through reference to actively managed reporting, such as documentation required to demonstrate compliance with the SPCC Plan, documentation required to demonstrate compliance with an approved erosion and sediment control permit, or by documentation specific to the SWPPP. The Site Environmental Coordinator(s) shall routinely evaluate the applicability of tasks as it relates to analytical and qualitative monitoring to determine if the preventative maintenance and good housekeeping program is adequate and performed frequently enough to control and minimize exposure to rainfall and storm water runoff. These inspections and tasks Page 19 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 can be collectively managed through E-Track and CAS to ensure they are performed and documented. A summary of the facility Preventative Maintenance and Good Housekeeping Program is provided in Appendix H. Duplicate documentation from other actively managed reporting and specific SWPPP documentation shall be maintained in Appendix H. 2.5 Facility Inspections NPDES Permit Reference: Part 1, Section A 21.2h Comprehensive inspections of the facility, including all storm water conveyance systems, shall be performed at a minimum of twice a year, once during the first half of the year (January to June), and once during the second half(July to December), with at least 60 days separating inspection dates (unless performed more frequently than semi-annually). These inspections are different from, and in addition to, the storm water discharge characteristic monitoring at outfalls described in Section 3.2. The Site Environmental Coordinator(s) shall ensure that inspection activities performed as part of the Preventative Maintenance and Good Housekeeping Program (Appendix H) or that may occur more frequently than semi-annually, sufficiently represent a comprehensive facility inspection. These inspections can be scheduled through E-Track to ensure they are performed and documented. Documentation for performance of the routine facility inspections is included in Appendix I. 2.6 Employee Training NPDES Permit Reference: Part 1, Section A 21.2e Training is conducted annually (at a minimum)for station personnel with responsibilities for spill response and cleanup, preventative maintenance activities, and plant operations that have the potential to contaminate storm water runoff. The training is conducted via online session and consists of a general understanding of storm water and its impacts on receiving waters with site specific information, and of the SPCC plan. Credit for completing the training is tracked electronically in lieu of gathering individual signatures. The Site Environmental Coordinator(s) shall maintain an annual summary of facility staff completing the training. The compilation of this information can be scheduled through E-Track to ensure it is performed and documented. Page 20 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 2.7 Responsible Party NPDES Permit Reference: Part 1, Section A 21.2f The Site Environmental Coordinator(s) shall be the primary responsible party for the overall coordination, development, review, amendment and implementation of the SWPPP.

Page 62 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Appendix H Best Management Practices Preventative Maintenance and Good Housekeeping Program (NPDES Permit number NC0039586: Part 1, Section A 21.2(d)) Page 63 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 HARRIS NUCLEAR PLANT BEST MANAGEMENT PRACTICES Best Management Practices (BMPs) are methods, procedures, processes, prohibitions of practices and other management controls which serve to eliminate, mitigate, or reduce pollutant loadings in storm water discharges. BMPs employed at the Harris Nuclear Plant include: • Source Reduction; • Good Housekeeping; • Preventive Maintenance; • Visual Inspections; • Spill Prevention and Response; • Erosion and Sediment Control; • Storm Water Runoff Management; • Employee Training; • Recordkeeping and Reporting; • Containment/Diversion; • Recycling; • Treatment. Source Reduction Source reduction measures minimize the potential for storm water pollution by reducing the quantity of materials which may contact storm water. Source reduction measures may require modifications in present work habits and practices, and may include components of: • Good Housekeeping; • Preventive Maintenance; • Visual Inspections; • Spill Prevention and Response; • Erosion and Sediment Control. Source reduction measures are addressed as main components of BMPs. Consequently, source reduction measures should be considered and included with the development and modification of any BMPs. Page 64 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Good Housekeeping Good housekeeping practices are designed to maintain a clean and orderly work environment. Good housekeeping practices should be incorporated in the day-to-day conduct of operations and maintenance. A clean and orderly work area reduces the possibility of accidental spills caused by the mishandling of chemicals and equipment. Well maintained material and chemical storage areas reduce the possibility of storm water mixing with pollutants. The following practices shall be performed on a regular basis: • Maintain clean and dry floors, ground surfaces, work, and process areas through the use of brooms, shovels, vacuum cleaners, mops and cleaning equipment; • Regular pickup and disposal of waste material; • Proper operation of equipment; • Routine visual inspections by qualified personnel for leaks or spills, and for conditions which may lead to a leak or spill (such as the hazardous waste inspections being performed at various areas throughout the Harris Nuclear Plant); • Training of employees in spill prevention and cleanup procedures; • Bags storing dry chemicals shall be raised off the floor, preferably by pallet, to prevent any unwanted interaction of the chemical and water; • Walkways shall be maintained free of obstructions to facilitate inspection for leaks or spills. At least once a year, the Pollution Prevention Team shall inspect work and storage areas to verify housekeeping is being maintained. Preventive Maintenance The Preventative Maintenance Program has been established and combined with the Facility Inspection Program. The Hazardous Materials, Gas, Oil, and Environmental Release programs are controlled by Plant Procedures. Any maintenance activities required will be incorporated into that program are noted. The Preventative Maintenance Program will follow the Facility Inspection Program. Facility walk downs and responsibilities for identification of deficiencies. AD-EN-ALL-0410 provides guidance for the oil and liquid waste management program. Operations personnel perform daily and weekly walk downs of the plant. Plant engineers perform periodic inspections of assigned areas documenting deficiencies. Inspections of the storm water control systems will occur when the storm water conveyances are visually inspected on a semiannual basis as EMP-003 procedure. This inspection will include clean out and maintenance of catch basins, ditches and material handling equipment. This program also combines inspections for lay down areas, outside storage areas, and secondary containment inspections. Page 65 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Preventive maintenance will be performed to ensure that storm water management facilities and controls operate correctly and effectively and to reduce their breakdowns and failure. Specific activities include: • Periodic inspection, cleanout and maintenance of catch basins, containment areas, ditches and material handling equipment; • Periodic scheduled inspection and testing of equipment and systems, including pumps, valves, pipes, storage tanks, and controls; • Proper scheduled maintenance of equipment and facilities. Additional preventive maintenance information will be provided as a separate section of the SWPPP Plan. Visual Inspections Visual inspections will be performed in accordance with the requirements of the facility SPCC Plan; and in conjunction with other BMPs such as housekeeping and preventive maintenance. Inspections may also be performed as a separate activity. When performed as an independent activity, the inspections will be performed by qualified personnel. The inspections will include reviews of past inspections and preventive maintenance, inspections of equipment, areas, and facilities, and any necessary follow-up. A record of each inspection will be maintained to verify that corrective measures are implemented on a timely basis. Inspections will include the following areas at a minimum: • Bulk oil and chemical storage tanks and containments; • Tanker loading and unloading areas; • Waste generation, storage, handling treatment, and disposal areas; • Sewage Treatment Plant and sewage lift stations; • Water Treatment Building, Neutralization Basin and Settling Basin; • Sandblast area; • Plant external lay down and storage areas; • Transformer Yard; • Switchyard and service transformers; • Cooling Tower area including pumps and water treatment chemicals and systems; • Security Training Facility and Firing Range; • Mobile Equipment Area; • Warehouse receiving and material handling areas; Page 66 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 • Paint Shop; • Construction and land disturbance areas; • Areas where past spills/leaks have occurred; • Pumps, valves, and control facilities. Specific items to be noted include: • Corroding or damaged drums, tanks, or other containers; • Damaged structural storage areas; • Inoperative or leaking pumps and valves; • Leaking or damaged piping or damaged piping supports; • Windblown/airborne dust/dry chemicals; • Inadequate erosion and sediment controls; • Evidence of seepages indicative of leaking underground piping; • Proper labeling of drums; • Evidence of leaks or spillage; • Warning labels present; • Rain water drained from secondary containments; • Rain water checked for oil or chemicals before release and documented. Spill Prevention and Response Spill prevention will be achieved by good housekeeping, visual inspection, and preventive maintenance, and through training of personnel in material handling and storage procedures, and the use of equipment. Training in proper spill identification and cleanup procedures, including the use of equipment and the notification and documentation procedures, will be the main components of spill response. Specific spill preventative measures will include: • Piping protection, such as routing, coatings and wrappings, and cathodic protection where appropriate; • Adherence to current unloading procedures and practices, including monitoring and verification of all connections, disconnections, and seals; • Proper valve and control settings, and adequate labels, markings, and communications, to ensure that accidental closures or openings do not occur; • Adequate security to prevent non-authorized access to facilities; • Appropriate documentation of actions taken. Page 67 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Spill response will be in accordance with existing Plant Procedures, including the Spill Prevention, Control and Countermeasure (SPCC) Plan. Training is essential to a well-executed Spill Response. Personnel will be trained to identify potential storm water pollution occurrences as may occur during a spill event, and respond in appropriate manner. Specific items in Spill Response include: • Establishment and training of the plant personnel in spill response, cleanup, documentation, and notification; • Safety measures; • Notification procedure for plant and the appropriate public authorities; • Safety and cleanup equipment; • Monitoring and verification of cleanup efforts. Erosion and Sediment Control Areas under construction involving land disturbing activities, or where accelerated erosion or sedimentation is occurring, will be monitored and corrective measures will be implemented as necessary. An Erosion and Sedimentation Control Plan and Permit is required for any land disturbing activities of one acre or greater. The Storm Water Pollution Prevention Team will decide if an Erosion and Sedimentation Control Plan and Permit is required. The NCDEQ Raleigh Regional Office of Energy, Mineral and Land Resources Division (DEMLR) shall be contacted as necessary to apply for and obtain any required permits. Typical temporary BMPs utilized to control erosion and prevent off-site sedimentation include silt fences, sediment traps and basins, rock check dams, wattles, and diversion channels. Permanent BMPs include riprap-lined channels, paved ditches, grassed channels, permanent storm water detention ponds, and permanent ground stabilization measures. Re-vegetation or equivalent stabilization of the disturbed areas will be performed to reduce/eliminate accelerated erosion and prevent off-site sedimentation. Storm Water Runoff Management Uncontaminated storm water will be diverted away from potential sources of contamination, and where possible, discharged to a stabilized conveyance structure. Contaminated waters will be directed to the appropriate treatment facilities prior to discharge. Diversion efforts should be made to reduce the quantity of contaminated storm water which must be collected and treated depending on conditions. Vehicle washing should be performed in areas that do not discharge through storm water outfalls. Page 68 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Employee Training Training programs are essential for providing employees with a complete understanding of the Storm Water Pollution Prevention Plan (SWPPP). Employee training at the Harris Nuclear Plant is conducted as necessary to inform and educate personnel who's work activities have the potential to impact storm water runoff of the components and goals of the SWPPP. General training of employees will emphasize good housekeeping, preventive methods, procedures, and practices. Responsibilities will be clearly communicated to personnel, including notification procedures for preventive and corrective measures. Maintenance and inspection personnel will have the authority to follow-up on areas requiring improvement. Plant personnel will be trained in safety and cleanup operations, and to recognize spill events which may contribute to storm water pollution. The Harris Nuclear Plant Spill Prevention Control and Countermeasure Plan (SPCC) requires training for all oil-handling personnel regarding ensure an adequate understanding of: • Proper operation and maintenance of equipment to prevent discharges of oil; • Procedures to follow upon discovery of any petroleum release; • SPCC Plan required inspection and documentation requirements; • Applicable pollution control laws and regulations; • Locations and use of release response and clean-up supplies, equipment and materials; • Description and causes of known petroleum releases at the facility; • Information on names and phone numbers for reporting releases to appropriate facility personnel; • General contents of the SPCC plan. All environmental training is conducted and assigned in MyTraining or Nuclearn. Training reports for annual SWPP and SPCC training can be printed as need. Training is assessed annually. Recordkeeping and Reports As part of the foregoing actions, plant personnel will have the responsibility to prepare the appropriate records to implement and maintain the SWPPP Plan. Page 69 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 September 2020 Containment/Diversion These measures require a physical structure or barrier to be installed to divert storm water away from potential pollutant sources or to contain potential pollutant sources. Diversion measures function best where runoff can be directed to a drainage channel where containment at the source is impractical. Containment functions best in areas where material will be permanently stored, handled, or used. Specific containment/diversion measures include: • Segregation of the work area; • Covering or enclosing the work area; • Diking the work area; • Diversion of storm water runoff, via pipes, and catch basins, or channels; • Dust controls. Recycling No recycling of contaminated storm water occurs at the plant. Recycling of some solid and hazardous wastes is performed and is coordinated by Environmental Services, Chemistry, and Material and Contract Services. Treatment Treatment measures will be the last step prior to the discharge of contaminated storm water. Treatment is employed at the plant for those areas where, due to site constraints, other BMPs have been found to be infeasible or too costly to implement. Storm drain flows, floor drains, runoff from material storage areas, and runoff from the Security Firing Range are the principle sources of contaminated storm water which must be treated.

Inspections and Training ❑ Inspect the maintenance area regularly to ensure BMPs are implemented. ❑ Train employees on waste control and disposal procedures. Material ❑ Store materials indoors. storage areas ❑ Cover material with a temporary covering made of polyethylene,polyurethane, polypropylene, or hypalon. ❑ Provide diversion berms,dikes or grassed swales around the perimeter of the area to limit run-on. ❑ Construct an enclosure or build a berm around the area. ❑ Regularly sweep area to minimize debris on the ground. ❑ Train employees in spill prevention,control,cleanup and proper materials management techniques. Fueling operations ❑ Conduct fueling operations(including the transfer of fuel from tanktrucks)on an impervious or contained pad or under a roof or canopy where possible.Covering should extend beyond spill containment pad to prevent rain from entering. ❑ When fueling in uncovered area,use a concrete pad(not asphalt,which is not chemically resistant to the fuels being handled). ❑ Use drip pans where leaks or spills of fuel can occur and where making and breaking hose connections. ❑ Use fueling hoses with check valves to prevent hose drainage after filling. ❑ Keep spill cleanup materials readilyavailable. ❑ Clean up spills and leaks immediately. ❑ Minimize/eliminate run-on onto fueling areas with diversion dikes,berms,curbing, surface grading or other equivalent measures. ❑ Collect stormwater runoff and provide treatment or recycling. ❑ Provide curbing or posts around fuel pumps to prevent collisions from vehicles. ❑ Use drycleanupmethodsforfuelarearatherthan hosing the fuel areadown. ❑ Perform preventive maintenance on storage tanks to detect potential leaks before they occur. ❑ Inspect the fueling area to detect problems before they occur. ❑ Discourage"topping off'of fuel tanks. ❑ Train personnel on vehicle fueling BMPs.

The permit application package modification consists of the following updated documentation: Enclosure 6— US EPA Form 2F—Stormwater Discharges Associated with Industrial Activity The update to Form 2F incorporates stormwater sampling as required by EPA Form 2F Section 7 for representative outfalls SW-003 & SW 006. Storm event sampling was conducted May 13, 2022, and Tables A through D have been updated accordingly. Due to misunderstandings associated with the difference between field parameter sampling timeframes and the samples to be collected within the first thirty minutes, the thirty minute samples were not collected. The short duration of the subject storm event analytical results (3 hours)should provide sufficient correlation between the flow-weight composite sample results and the anticipated results from thirty-minute grab samples. The application modification information is also being transmitted electronically and via USPS to Ms. Brianna Young, Industrial Individual Permit Coordinator in the Central Office, and to Ms. Lauren Garcia, Environmental Specialist, in the Raleigh Regional Office.

The evaluation shall determine if a non-storm water discharge is present or otherwise how that discharge is permitted or otherwise authorized. Supporting evaluation information and a copy of the certification shall be included in Appendix E. Allowable non-storm water discharges include: • Foundation drains and natural springs; • Flows from riparian habitats and wetlands; • Air conditioner condensate that includes no added chemicals; • Waterline and fire hydrant flushing; • Discharging from fire-fighting, fire-fighting training, and fire system testing; • All other discharges authorized by an NPDES permit. 2.2 Storm Water Management Strategy 2.2.1 Feasibility Study NPDES Permit Reference: Part/, Section A 21.2b(1) This section provides a review of the technical feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and processes to rainfall and storm water runoff. Below are descriptions of the existing operations at the plant that present the potential for negative impacts to storm water runoff. These descriptions demonstrate the current practices in use to prevent exposure of storage areas, material handling operations and fueling operations. Page 7 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 DIESEL FUEL AND GASOLINE STORAGE Diesel fuel and gasoline is stored at the plant in several different tanks and containers at the plant. The diesel fuel is primarily used as fuel for emergency diesel generators at the plant. The diesel fuel and gasoline is used to fuel plant vehicles and miscellaneous equipment. The largest containers at the plant are two 175,000 gallon underground diesel fuel storage tanks located north of the plant, and two 110,000 gallon field-erected aboveground diesel fuel storage tanks located in the southwestern area of the plant yard. The aboveground tanks are located within a single common concrete secondary containment structure equipped with a closed drain valve. Drainage from the containment discharges into the plant 10,000 gallon capacity Oil/Water Separator. The plant contains eight additional aboveground diesel fuel tanks, one aboveground gasoline tank, and numerous 55 gallon petroleum storage drums. The remaining tanks are small, shop-fabricated steel tanks maintained at various locations around the plant. The plant contains one 1,000 gallon underground diesel fuel storage tank at the Security Building, and one 10,000 gallon underground diesel fuel storage tank and one 10,000 gallon underground gasoline storage tank in the Mobile Equipment Area. The plant also maintains one small diesel fuel tank and one small gasoline tank on a mobile fuel truck. A complete listing of these containers, including inspection and testing requirements, secondary containment descriptions and inspection requirements, and tanker unloading operation requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All diesel fuel and gasoline storage tanks are provided with some means of passive secondary containment or are integral double-walled containers as described in detail in the Harris Nuclear Plant SPCC Plan. All external containments are inspected prior to being manually drained in accordance with the SPCC Plan. Secondary containments either drain into the plant 10,000 gallon capacity Oil/Water Separator, or onto the plant yard. Mobile tanks are stored in areas that drain to the Oil/Water Separator while in standby mode. Refueling operations for all diesel fuel and gasoline containers are conducted in constant attendance in accordance with plant procedures and the Harris Nuclear Plant SPCC Plan. Tanker trucks are brought on-site to refill the two 175,000 gallon underground diesel fuel storage tanks and the two aboveground 110,000 gallon diesel fuel storage tanks. Tanker unloading into the two 175,000 gallon underground storage tanks, and into the two 110,000 gallon aboveground storage tanks, is conducted on a concrete containment pad adjacent to the tanks. The containment is equipped with open drains to the Oil/Water Separator. Tanker trucks are also brought on-site to refill the other aboveground and underground diesel fuel and gasoline tanks. These tankers unloading operations are conducted adjacent to the containers and in constant attendance in accordance with plant procedures. Prior to filling any container, tank levels are verified by electronic high-level and low-level annunciators, visual sight glasses, or are otherwise verified as described in the plant SPCC Plan. Page 8 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 The plant contains diesel fuel piping primarily associated with the delivery of diesel fuel from the two 110,000 gallon aboveground diesel fuel storage tanks to the emergency diesel generator system, and to other locations and systems. The piping is located aboveground or within concrete trenches. None of this piping is in contact with the soil. Portions of this piping are located within the secondary containment structure surrounding the tanks or at the fuel forwarding skid within the containment pad for the tanker unloading station. All aboveground piping outside of these concrete containments, and all piping within the concrete trenches, is provided secondary containment by open drains to the Oil/Water Separator. Diesel fuel transfer operations from the tanks to the emergency diesel generator system is an automated process. Facility operations personnel conduct daily routine facility walk-downs to observe all aboveground piping, valves, expansion joints, flange joints, and structural supports. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with diesel fuel and gasoline storage practices or tanker unloading operations at the facility. All diesel fuel and gasoline containers are in compliance with the plant SPCC Plan. USED OIL STORAGE AND HANDLING Used oil is collected and stored in eleven small tanks and containers at the plant. The largest used oil tanks are one 4,000 gallon steel tank and one 2,000 steel gallon tank in the Mobile Equipment Area. These two tanks are within a common concrete containment structure. There is a 1,000 gallon steel used oil tank adjacent to the.Oil/ Water Separator that collects used oil removed by the separator. This tank is within the same concrete containment pad as the separator. There is a 1,000 gallon steel used oil tank adjacent to the Emergency Diesel Generator Building and within a concrete containment structure. There are three 220 gallon poly used oil containers at the plant. Two of these containers are within a common metal containment bin on a covered concrete pad at the Paint Shop. The remaining container is within a concrete containment structure in the Mobile Equipment Area. The plant has a 1,000 gallon steel used oil tank mounted on a mobile trailer. While in standby mode the trailer is maintained in an area of the plant with yard drains that discharge into the Oil/Water Separator. There is a 100 gallon hydrogen seal oil drain tank within a concrete containment structure adjacent to the Turbine Building, and a 200 gallon oil filter drain tank inside the Mobile Equipment Building. The plant also maintains two 55 gallon used cooking oil drums maintained within a poly containment shelter at the east end of the Service Building. A complete listing of all used oil tanks, including inspection and testing requirements, secondary containment descriptions and inspection requirements, and tanker loading operation requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All external containments are inspected and manually drained in accordance with the SPCC Plan. Secondary containments either drain into the plant 10,000 gallon capacity Oil/Water Separator, or onto the plant yard. Mobile tanks are stored in areas that drain to the Oil/Water Separator while in standby mode. Tanker trucks are brought on-site to load used oil as needed from the Page 9 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 various used oil tanks. The tanker loading operations are conducted adjacent to the containers and in constant attendance in accordance with plant procedures. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with used oil storage practices or tanker loading operations at the facility. All used oil containers are in compliance with the plant SPCC Plan. LURE OIL STORAGE The plant has three lube oil storage tanks consisting of one 14,000 gallon Turbine Generator Batch Oil Tank and two 1,500 gallon Turbine Lube Oil Sump Tanks. All three tanks are located within concrete containment basins inside the Turbine Building. The inspection and testing requirements for these lube oil tanks is described in detail in the Harris Nuclear Plant SPCC Plan. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with these lube oil tanks. OIL-FILLED EQUIPMENT AND SYSTEMS Oil-filled equipment and systems at the plant includes lubrication oils, mineral oils and hydraulic oils maintained within closed conduit systems. These oils are used in hydraulic systems, lubricating systems, gear boxes, machining coolant systems, heat transfer systems, transformers and circuit breakers. Oil-filled equipment and systems, including container inspection requirements and secondary containment descriptions and inspection requirements, are described in detail in the Harris Nuclear Plant SPCC Plan. The plant contains four lube oil and hydraulic oil reservoir systems located inside the Turbine Building. These reservoir systems are not exposed to storm water. Any oil release occurring from these systems will enter open floor drains that discharge into the plant Oil/Water Separator. The largest oil-filled equipment containers exposed to storm water are large transformers containing mineral oil and located in the Transformer Yard on the east side of the Turbine Building. This equipment consists of three 9,180 gallon Start-Up Transformers, four 7,780 gallon Main Step-Up Transformers, and two 5,500 gallon Auxiliary Transformers. All of these transformers are within a concrete containment sump equipped with a manually operated dewatering pump. Containment contents are inspected in accordance with the plant SPCC Plan prior to dewatering, and sump contents are pumped to the plant Oil/Water Separator. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the large transformers. Smaller oil-filled equipment containers exposed to storm water include numerous pad-mounted service transformers containing mineral oil located at various locations around the plant. These Page 10 of 88 I STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 transformers are used to provide power to the various buildings and facilities at the plant, and are generally not provided with any means of passive secondary containment. Any mineral oil release occurring from these service transformers would result in failure of the unit and subsequent loss of power. The plant relies on system monitoring, frequent inspections, preventative maintenance, and active containment measures as described in the plant SPCC Plan to contain any potential release occurring from these transformers. A mineral oil release from these units will typically discharge vertically into the underlying conduit penetrations which will provide some degree of containment. The potential for storm water impacts associated with mineral oil releases from any of these uncontained pad-mounted transformers is minimal, and could be reduced by the installation of dedicated secondary containments with manually operated drain valves or open drains to the Oil/Water Separator. CHEMICAL STORAGE AND HANDLING Various chemicals are used at the plant for water treatment and other purposes. Bulk chemicals are delivered by tanker trucks and unloaded into respective storage tanks at designated locations. Smaller chemical containers and drums are delivered to the receiving area of Warehouse 9 for storage or subsequent transport via company vehicles to the Water Treatment Building, Paint Shop, Bulk Warehouse, Chemical Warehouse, the Sewage Treatment Plant, and other locations. Plant personnel are trained in safe forklift usage, safe handling of chemicals, and proper use of spill containment and cleanup materials. Spill kits are located at receiving areas. Two 5,500 gallon sodium hypochlorite tanks, one 5,600 gallon phosphoric acid tank, three 4,500 gallon water treatment chemical storage tanks and other smaller chemical containers are used for water treatment and analysis purposes at the Cooling Tower. The sodium hypochlorite tank and other small tanks and containers are within a concrete containment. The containment can be drained to the yard drainage system or can be pumped into the Cooling Tower basin. Small containers of chemicals used for analysis are stored inside the chemical storage building. Four bulk chemical storage tanks, consisting of a 10,800 gallon caustic tank, a 7,500 gallon sulfuric acid tank, a 1,500 gallon empty ammonia tank, and a liquid nitrogen to gaseous nitrogen tank are located at the south end of the Turbine Building. These tanks are within containments that can be drained to the yard drainage system or to a sump that discharges to the Oil/Water Separator. An 8,315 gallon sulfuric acid storage tank is located at the east end of the Water Treatment Building. This tank is within a concrete containment with an open drain to a sump that pumps to the Neutralization Basin. Sodium carbonate, sodium hypochlorite, sodium hydroxide, and water treatment polymers are stored in tanks and containers at the Sewage Treatment Plant. Some of these tanks and containers are stored in totes inside metal buildings with built-in sumps. All chemical storage tanks and containers are provided with some means of containment consisting of secondary containment structures with manually operated drain valves, secondary Page 11 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 containment structures with open drains to other containment or treatment systems, or are stored inside buildings. All external containments with drain valves are inspected prior to boing manually draining. All chemical deliveries are conducted adjacent to the containers or at receiving areas in constant attendance and in accordance with plant procedures. Chemical container levels are verified prior to initiating any tanker unloading operation. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the storage and handling of chemicals. WASTE HANDLING AND STORAGE Waste chemicals and oils produced inside the protected area of the plant is typically transported to and processed in the chemical processing area of the Paint Shop. These materials are stored within a covered concrete containment area with open drains to the Oil/Water Separator. Waste chemicals produced outside the protected area of the plant are typically transported to, processed and stored in Warehouse 6. Waste oils produced outside the protected area of the plant are typically transported to the used oil tanks in the Mobile Equipment Area. Hazardous materials are accumulated in designated satellite waste storage areas at the plant. All satellite accumulation areas are either under shelters or are inside buildings. All hazardous waste generated at the plant is eventually transported to and stored in the Central Hazardous Waste Storage Area located under a shelter attached to the Chemical Warehouse. Dumpsters and roll-off containers are used at certain locations to collect inert materials and solid waste for disposal. No liquids or other materials that could potentially impact storm water are disposed of in external dumpsters. Two closed trash compactors are located west of the Chemical Warehouse. Recyclable waste materials are collected in covered storage containers at several locations inside buildings. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with waste handling and storage. EXTERNAL STORAGE, LAYDOWN AND PARKING AREAS Inert materials such as miscellaneous wood, structural steel, cable, empty drums and other metal components are stored at various external laydown yard areas at the plant. These laydown areas are typically paved or gravel-surfaced. No liquids or materials that could potentially impact storm water are stored on external laydown areas. Cranes and other mobile equipment are parked on the crane laydown yard and in other external parking and storage areas. This equipment can contain oils, fuels, hydraulic fluids and other materials that represent potential storm water impacts. Plant employees are trained to promptly report and respond to spills. Page 12 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 Other materials such as soil, sand, gravel, compost, concrete and asphalt may be stockpiled at certain locations on a temporary basis until the material can be recycled, reused or properly disposed of off-site. Stockpiled materials such as soil that could potentially result in the mobilization of sediments when exposed to rainfall are covered, stabilized by temporary or permanent seeding or are otherwise provided with necessary sediment control measures. Drainage areas containing external storage, laydown and parking areas are described in Appendix B. The potential for storm water impacts associated with these external areas could be reduced by covering materials such as soil, gravel, treated lumber, flaking painted surfaces and other materials that represent the greatest potential for such impacts, by regular inspections and maintenance of mobile equipment, and by maintaining mobile equipment inside temporary containments while parked. Constructing permanent shelters over these external areas to prevent contact with storm water is cost prohibitive. SECURITY TRAINING AND FIRING RANGE The plant maintains a designated facility for security training purposes that includes an external firing range. The range is located west of the plant on the north side of the Emergency Service Water Intake Canal. Lead-based ammunition is routinely fired into bullet traps at the range. Storm water runoff from this area flows south and southwest overland into the adjoining Emergency Service Water Intake Canal. The embankment soil pH is routinely monitored and maintained within a range to prevent the lead from becoming soluble. Security personnel maintain an inventory of expended rounds fired and routinely harvesting lead from bullet traps or the soil. There are no changes warranted to reduce the potential for impacts to storm water runoff associated with the security training and firing range. Constructing permanent shelters over the firing range to eliminate exposure to rainfall is cost prohibitive. Duke Energy continuously pursues strategies to holistically manage the exposure of storm water to power generation, waste disposal, and facility management operations. These efforts consider the technical and economic feasibility of changing the methods of operations and/or storage practices. The details from the planning, design, and construction of such improvements shall be incorporated into the SWPPP upon completion. Page 13 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 2.2.2 Secondary Containment Requirements and Records NPDES Permit Reference: Part 1, Section A 21.2b(2) The plant manages numerous oil-based liquids and non-oil based liquids and chemicals which are critical to power generation and transmission, water treatment, waste handling and treatment, and operation of vehicles and equipment. The Harris Nuclear Plant is subject to the requirements of U.S. Environmental Protection Agency (EPA) Oil Pollution Prevention Regulation 40 CFR Part 112 because the oil storage capacity at the facility exceeds 1,320 gallons and the proximity to waters of the United States. As a result,the facility maintains a Spill Prevention, Control, and Countermeasures (SPCC) Plan pursuant to, 40 CFR Part 112. This plan addresses secondary containment, inspections and record keeping requirements for all oil containers of 55 gallon capacity and greater. A copy of the SPCC is not included in the SWPPP as the document is actively managed at all times for evolving site conditions; however, a current version is maintained in the Nuclear Fusion document data base and a version with mark-ups is maintained in the office of the Site Environmental Coordinator(s) and referenced herein. Pursuant to this section of the permit, secondary containment is required for the bulk storage of liquid materials, storage in any amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act(SARA)water priority chemicals, and storage in any amount of hazardous substances, in order to prevent spills and leaks from contaminating storm water runoff. Secondary containments shall be sized to contain the full capacity of the single largest container within the containment structure. Secondary containments exposed to precipitation shall also have additional capacity to contain the 25-year, 24-hour storm event. This additional capacity requirement shall take into consideration any storm water runoff entering the containment structure from upland areas if applicable. Secondary containments draining into storm water conveyance systems or onto the ground surface shall be equipped with manually- operated, lockable or otherwise secured drain valves or dewatering pumps. Flapper-type valves shall not be used. Accumulated storm water within secondary containments shall be visually inspected for color, foam, outfall staining, presence of sheen, oils or chemicals prior to release in accordance with the frequencies specified in the plant SPCC Plan. Inspections will include observation for leaks, condition of containment, valve drain closure and locking, and presence of excessive debris and sediment. Inspection records shall be maintained at the facility. Exterior containments exposed to precipitation shall be inspected promptly after any significant rainfall event, and collected water within containments shall be drained to maintain adequate spill storage capacity within the containment. A list of all liquids and chemicals and their associated secondary containment provisions are provided in Appendix F. Documentation for periodic inspections for leaks and recordation of accumulated storm water releases shall be placed in Appendix I. Page 14 of 88 STORM WATER POLLUTION PREVENTION PLAN Revsion 5 May 2020 2.2.3 Best Management Practices (BMPs) Summary NPDES Permit Reference: Part 1, Section A 21.2b(3) A number of best management practices are currently in place at the station. These BMPs were instituted over a number of years as a result of various regulatory drivers and good housekeeping objectives. While a chosen practice provides some level of pollution prevention as it relates to the management of storm water discharges under this permit, the historic rationale behind implementing such a practice is comprehensive of a number of contributing factors. To document the ongoing implementation of these practices as part of the SWPPP, Table 2 from the Industrial Storm Water Fact Sheet for Steam Electric Power Generating Facilities (EPA-833-F-06-030)was reviewed and evaluated, and is provided in Appendix O. A high-level review of the BMPs is provided below along with a rationale for implementation. The detailed listing of these BMPs for each drainage area is provided in the outfall descriptions in Appendix B where information regarding the industrial activities and significant sources of pollutants are also compiled. The compiled information in the appendix captures an ongoing assessment process for BMP selection and implementation. The Site Environmental Coordinator(s) shall rely on Table 2 from EPA-833-F-06-030 for the improvement, installation and implementation of BMPs to address data collected through monitoring of storm water discharges. The Site Environmental Coordinator(s) may also rely on other sources of information to develop and implement appropriate BMPs not specifically listed in Table 2. This list of BMPs shall be reviewed and updated annually as new practices are incorporated in the plan or warranted as a result of exceedances of analytical monitoring benchmarks detailed in the permit. FUGITIVE DUST EMISSIONS The potential for fugitive dust to impact storm water runoff drives the need for emission management practices. The station maintains an air permit with NCDEQ that includes the control of fugitive dust emissions as a programmatic requirement. Fugitive dust emissions are managed as necessary through a variety of BMPs that include restricting frequent traffic to paved roadways, periodic wetting of haul roads, and permanent stabilization of dust generating surfaces. Fugitive dust control is typically a contractual requirement of any contractors brought on-site to perform services that may involve the creation of fugitive dust. Fugitive dust generation is typically insignificant at the facility. LOADING AND UNLOADING OF FUELS,OILS AND NON-OIL LIQUIDS AND CHEMICALS The plant maintains numerous locations for the loading and unloading of fuels, oils and non-oil liquids and chemicals. The potential for spills and leaks to release to storm drains or overland drainage pathways to receiving waters presents a source of unauthorized discharges and potential storm water contamination. Loading and unloading operations follow plant procedures, the requirements specified in the plant SPCC Plan, and the requirements specified in the DOT unloading/loading procedures 49 CFR Part 177, Subpart B.
