See Section 6 (below) Facility Location: Lat: 35'13'08" N; Long: 81°46'03" W Section 1. Facility Activities and Process: The Rogers Energy Complex (formerly Cliffside Steam Station) is a coal fired electric generating facility operated by Duke Energy Carolinas, LLC (Duke Energy). The facility is located on Duke Power Road, off NC State Road 1002 just south of Cliffside North Carolina, on the Broad River. The facility currently has two units (Units 5 and 6). Units 1 through 4 were retired in October 2011. The Broad River supplies the Condenser Cooling Water (CCW) and other service water systems from the intake located just upstream from the diversion dam on the Broad River. The pumps have traveling screens for debris removal. Debris collected on the screens consist of twigs, leaves, and other material indigenous to the river and is flushed back to the river. Within the switchyards and buildings, runoff flows over land to ditches and catch basins and underground piped conveyances. Stormwater from areas with significant materials or activities is routed through treatment systems prior to discharge. Stormwater runoff from the plant yards, coal handling areas, coal pile, Units 5 and 6, and the FGD site goes to the yard drainage basin, effluent from the holding basin is pumped to the ash basin. Stormwater runoff from the switchyards is routed through oil tank traps prior to discharge. Page 1 of 14 Per an email dated December 9, 2020, SW018A and SW018B were physically removed on December 2, 2020 as part of the ash storage area closure activity. Per the renewal application, the following significant changes have occurred since the last issued permit: • ROS approved for: o SW001 representative of SW002 o SWO11 representative of SW012 o SW015-13 representative for SW015-1 to SW015-13 o SW016-42" representative for SW016-24", -30", -36", and -54" o Landfill Drainage-18" representative of Landfill Drainage-2 1", -36", -42" ■ Per original request and info from MRO, -36" should be the representative outfall, not -18" ■ Based on monitoring data provided, -36" is the ROS as monitoring for the other outfalls ceases o SW018A representative of SW018B • SW007 was plugged • No industrial activities associated with SW008, SWO10, SW019, and Unit 6 switchyard • Haul road to the ash landfill was paved • 3 large basins constructed to collect wastewater and stormwater. Stormwater runoff received in these basins is processed in the WW treatment system. Per an email dated 12/28/2021, the Basement Basin is one of the three basins constructed since the stormwater permit was last issued. The three basins discharge through NPDES Permit NC0005088 - Outfall 005, and the emergency overflow is also covered in NC0005088 as outfall 002B for the Basement Basin and Outfall 002C for the Holding and Aux Storage Basins. Outfall SW001 (Drainage Area 1) Drainage Area 1 includes the Unit 5 115 kV switchyard and relay house. The Unit 5 switchyard had ash placed under the gravel when it was constructed in 1970's time frame. SW001 currently has oil filled transformers and an oil water separator. The switchyard is fenced and covered with gravel (approximately 1 foot of gravel over a layer of ash which was used as fill material), relatively flat, and elevated slightly above the surrounding area. The southern and western perimeters are curbed and ditches divert runoff around the switchyard. There is approximately 2 acres of gravel area and 1 acre of paved roadways within the drainage area. Approximately 30% of the drainage area is impervious. Stormwater runoff flows to a 30,000 gallon oil trap tank. Outfall SW002 (Drainage Area 2) Drainage Area 2 includes the Unit 5 239 kV switchyard. The Unit 5 switchyard had ash placed under the gravel when it was constructed in 1970's time frame. SW002 drains the upper switchyard that has air cooled transformers plus two small transformers that have —65 gallons of oil in each. The switchyard is covered with gravel (approximately 1 foot of gravel over a layer of ash which was used as fill material), relatively flat, and elevated slightly above the surrounding area. The southern and eastern perimeters are curbed, and ditches divert runoff around the switchyard. There is approximately 2.7 acres of gravel area and 1 acre of paved roadways within the drainage area. Approximately 40% of the drainage area is impervious. Page 2 of 14 Outfall SW003 (Abandoned) Outfall SW003 formerly conveyed stormwater runoff from industrial activities surrounding the Unit 5 Powerhouse. The outfall was plugged and abandoned around 2010 and all stormwater runoff is conveyed to the lined basement drainage basin (per email dated 12/28/2021). As long as outfall SW003 does not discharge, no analytical sampling is required. Any modifications to these outfalls that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall SW004 (Drainage Area 4) Drainage Area 4 includes Units 1 through 4 switchyards. The switchyard is covered in gravel, elevated slightly above the surrounding area, and curbed except the northwest end. Less than 5% of the drainage area is paved. Stormwater runoff from switchgear equipment flows to a 20,000 gallon oil trap tank. Outfall SW005 (Drainage Area 5) Trenches are used to return river water used to wash debris from the intake screens. The trenches are covered with grating and deigned to prevent run-on from adjacent areas. Per the 2020 permit renewal application, Unit 1-4 Powerhouse had been converted to a lined holding cell. Per an email dated 12/28/21, roof drains from Units 1 through 4 turbine rooms are no longer present as the buildings were removed; part of the French drains still exist and receive stormwater around the water intake structure (which is SW005). The 12/28/2021 email also stated the basement was converted to the Basement Basin to receive stormwater and process water discharged though NPDES permit NC0005088. The Basement Basin is one of three basins constructed since the stormwater permit was issued. The three basins discharge through NC0005088 Outfall 005. The emergency overflow is also covered in NC0005088 as outfall 002B for the Basement Basin and Outfall 002C for the Holding and Auxiliary Storage Basins. Outfall SW006 (Abandoned) Outfall SW006 has been abandoned and the drainage area sheet flows to the CCW discharge canal. Per an email dated 12/28/2021, SW006 had one inlet grating that drained a small area; part of this area was filled in with the demolition of Units 1 thru 4 and building the Basement Basin, and the discharge pipe was filled with flowable fill. As long as outfall SW006 does not discharge, no analytical sampling is required. Any modifications to these outfalls that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall 007 (Abandoned) Outfall 007 has been abandoned (plugged March 2016) and the drainage area is routed to the lined basement basin (per email dated 12/28/2021). Formerly an emergency and drainage basin overflow, mixed with industrial waste. Any modifications to this outfall that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall SW008 (Drainage Area 8) Drainage Area 8 previously discharged in -stream sand mining wastewater, stormwater runoff, and wastewater under NPDES permit NCG520000. Operations ceased in 2012 Page 3 of 14 and there no longer is a discharge. As long as outfall SW008 does not discharge, no analytical sampling is required. Any modifications to these outfalls that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall SW009 (Drainage Area 9) Drainage Area 9 includes the inactive Unit 5 ash basin, a soil/stockpile area, a pond, and three laydown areas. Stormwater runoff is collected and conveyed to a sedimentation basin. Overflow from the sedimentation basin is conveyed to a rock channel and then discharged to the Broad River. Outfall SWO10 (Drainage Area 10) Drainage Area 10 conveys water from a perennial stream. As long as outfall SWO10 only conveys water from a perennial stream that starts from the adjoining property, runs under the switchyard, and enters a channel, no analytical sampling is required. Any modifications to these outfalls that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall SWO11 (Drainage Area 11) Drainage Area 11 conveys stormwater runoff from a gravel parking area, approximately 13 acres of gravel laydown areas, and approximately 1,500 feet of railroad tracks into a sedimentation basin. Runoff is conveyed into sediment basin and discharged via pipe. Outfall SW012 (Drainage Area 12) Drainage Area 12 includes a gravel parking lot, locomotive storage building, a 600 gallon oil water separator, a portion of the Unit 6 cooling tower, a portion of the gypsum and fly ash haul road, and railroad tracks. Stormwater runoff is conveyed to a sediment basin that discharges to Suck Creek. Drainage Area 13 (combined with Drainage Area 16, Per previous fact sheet) Drainage Area 13 was combined with Drainage Area 16. There is no drainage area 13. Any modifications to these drainage areas that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Drainage Area 14 (Sheet flow) Any modifications to Drainage Area 14 that result in a potential stormwater discharge associated with past or present industrial activities will require a permit modification. Outfall SW015 (Drainage Area 15) SW015 represents a series of 13 high density polyethylene (HDPE) pipes (8 inch diameter). Drainage Area 15 includes railroad tracks where limestone is loaded/unloaded from rail cars. Outfall SW016 (Drainage Area 16) Drainage Area 16 includes approximately 5,000 feet of railroad tracks, a gravel parking lot and laydown area, a portion of the haul road to the fly ash/gypsum landfill, and part of Duke Power Road. SW016 represents a group of outfalls that include five separate corrugated metal pipe (CMP) outfalls (36 inch, 30 inch, 42 inch, 24 inch, and 54 inch). Runoff is conveyed into sediment basins. Page 4 of 14 qwn 1 7 Drainage area includes runoff from an access road leading to the active ash basin. The road is paved to the intersection with other gravel roads and runoff is collected and conveyed by roadside ditches. SW018A (Abandoned) Drainage areas include runoff from natural areas and access roads leading to the active ash basin. There is a legacy ash structural fill in the drainage area but it is stabilized with an earthen cover and vegetated. The roads are mostly gavel throughout the drainage area. There are currently no industrial activities performed in the drainage area. This structure was physically removed. SW018B (Abandoned) Drainage areas include runoff from natural areas and access roads leading to the active ash basin. There is a legacy ash structural fill in the drainage area but it is stabilized with an earthen cover and vegetated. The roads are mostly gravel throughout the drainage area. There are currently no industrial activities performed in the drainage area. This structure was physically removed. SW019 (Closed out) Drainage area includes runoff from an access road leading to the ash basin outfall bordered on either side by natural area. The road is paved from the intersection with other gravel roads and runoff is collected and conveyed by roadside ditches. There are currently no industrial activities performed in the drainage area. This outfall has been closed out and the area drains by sheet flow. Landfill Drainage Area (LDA) Drainage area has four (4) separate corrugated metal pipe outfalls (18 inch, 42 inch, 36 inch and 21 inch) and consists of approximately 2,000 feet of railroad tracks, a portion of the haul road to the fly ash/gypsum landfill, exterior landfill slopes, and non -contact landfill stormwater. Stormwater runoff from inactive cells and exterior slopes drain to a sedimentation basin and then through one of four (4) separate outfalls. Stormwater runoff from active cells at the landfill is directed into the leachate collection system, pumped to the leachate collection basin, then to the ash basin (see below). Per an email dated 12/28/2021, the landfill would be built in 5 phases, with 4 phases now having been constructed and 3 phases receiving Coal Combustion Residual (CCR) material. Phase 4 water is currently considered storm water since it has no contact with CCR material. When CCR will be placed in cell 4, it will be treated as leachate and processed thru NPDES wastewater permit NC0005088 - Outfall 005. To maximize land use, soil is removed from the landfill area during construction and a liner installed on the side slopes and bottom where the soil was excavated, creating a containment/barrier for stormwater or CCR contact water (leachate) from ground water. During construction and until stormwater contacts CCR, it is treated as non -contact stormwater. Once stormwater contacts CCR it is treated as leachate and processed through NPDES NC0005088. Some of the landfill phases were engineered to have divider cells to separate stormwater within the phases until CCR is placed in the cell to reduce the amount of leachate generated. As CCR is placed in the landfill, the landfill grows in height. Any stormwater that falls on Page 5 of 14 the outside slope of the landfill is treated as noncontact stormwater since it has not contacted any CCR material. The stormwater that falls on the inside slope of the landfill is treated as leachate since it has contacted CCR material. Once the landfill reaches the engineered height, a liner system will be installed on the top and sides of the landfill in addition to a protective cover material. Once the landfill is completed and covered, all the stormwater will be treated as non -contact stormwater. The 12/28/2021 email also states that stormwater that contacts CCR is treated as leachate. Per the email, a drainage system in the base of the landfill directs water to a leachate pump system that removes the water from the landfill. The leachate is pumped to a concrete leachate basin and then pumped to the Unit 6 process wastewater drain system. The water is discharged through NPDES permit NC0005088 — Outfall 005 after it is treated. Per the email, a new WWTP was installed to replace the ash basin Outfall 002, therefore the outfall description should state that the leachate collection basin is pumped to the Unit 6 process drains and discharges through NPDES NC0005088 Outfall 005. Unit 6 Switchyard Area Drainage area includes the Unit 6 500 kV switchyard. The switchyard is relatively flat and elevated slightly above the surrounding area. A curb surrounds the southern and eastern perimeters and ditches divert upland runoff around the switchyard. Drainage from the 11.8 acres of gravel surface (with access roadways) is conveyed via three concrete culverts, an 18 inch, 24 inch and 30 inch. The runoff then shallow flows toward the Broad River. Laydown Area #2 (LA2) Stormwater runoff from the area is collected in a sedimentation basin. Overflow would be conveyed to a nearby stream that feeds into the Broad River, but overflow is not a normal occurrence. Runoff conveyed into sediment basins is discharged via rock weir. 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 by-products 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, by-product, or waste product. The term excludes areas located on plant lands separate from the plant's industrial activities, such as office buildings and accompanying Page 6 of 14 parking lots as long as the drainage from the excluded areas is not mixed with storm water [sic] drained from the above described areas."

Proposed Monitoring for Stormwater Discharges: The Division considered potential pollutants from past and present industrial activities (coal-fired electric generation, plant decommissioning, and future ash removal). 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 (e.g., ash removal through the drainage area). 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 (e.g., ash removal through the drainage area). Below are tables of the proposed monitoring for each outfall at the Rogers Energy Complex site.

Outfalls will be impacted by Coal Ash Excavation. Total Hardness Quarterly monitoring BASIS: Monitoring is required for hardness dependent metals Stormwater Benchmarks and Tiered Response: Rather than limits, North Carolina NPDES Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action levels for stormwater monitoring. Benchmarks are not effluent Page 9 of 14 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 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 Antimony Total 340 /L ECOTOX database, '/2 FAV Arsenic Total 340 /L Acute Aquatic Criterion, '/2 FAV Beryllium Total 65 /L Acute Aquatic Criterion, '/2 FAV Boron 34,000 µg/L CCW/Coal constituent; Narrative National Recommended Water Quality Criterion Cadmium Total 3 /L Acute Aquatic Criterion, '/2 FAV '/2 FAV, based on (Cr III + Cr VI) acute Chromium (Total) 905 µg/L thresholds and assumption that industrial activities here are not a source of hexavalent chromium Copper Total 10 /L Acute Aquatic Criterion, '/2 FAV Lead Total 75 /L Acute Aquatic Criterion, '/2 FAV Mercury (Total) 12 ng/L CCW/Coal Constituent; Hg influenced by regional transport and wet deposition Nickel (Total) 335 µg/L Acute Aquatic Criterion, '/2 FAV Page 10 of 14 Selenium is a bio-accumulative metal; Selenium (Total) 5 µg/L Recommend using the current chronic 02B standards for freshwater 5 /L Silver Total 0.3 /L Acute Aquatic Criterion, 1/2 FAV Thallium (Total) 2,000 µg/L CCW/Coal constituent; National Recommended Human Health Criterion Zinc Total 126 /L Acute Aquatic Criterion, 1/2 FAV The aquatic life standard is 0.001 µg/L.

PCB Because PCBs cannot be quantified below the compounds detection limit, any detection is considered an exceedance of the benchmark. Total Suspended 100 mg/L National Urban Runoff Program (NURP) Study, Solids TSS 1983 H 6 s.u. — 9 s.u. NC Water Quality Standard (Range) Non -Polar Oil & Review of other state's daily maximum Grease, EPA 15 mg/L benchmark concentration for this more targeted Method 1664 O&G; NC WQS that does not allow oil sheen in SGT-HEM 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. Mercury Monitoring Requirements: The proposed permit requires mercury to be measured in stormwater samples by EPA Method 1631E, which can detect levels as low as 0.5 ng/l. This requirement is consistent with recent federal rule -making that requires NPDES permittees to monitor discharges with sufficiently sensitive test procedures approved under 40 CFR § 136. Modifications to 40 CFR § 122.44(i) require a method that has a minimum level (ML) at or below the effluent limit (not applicable here), or the lowest minimum level (ML) of EPA approved analytical methods for the measured parameter. Based on results, Method 1631E will be required to quantify levels in these discharges. NC DEMLR understands that this method is more costly and requires a more intensive sampling protocol than most other parameters. Page 11 of 14 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. This site may trigger this requirement during demolition or ash removal activities. • Proposed federal regulations will 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. Section 3. Changes from previous permit to draft: • Monitoring increased from semi-annually to quarterly for all parameters (qualitative and quantitative) • "No discharge" clarifications made • 'No requirement added • Boilerplate language moved into body of the permit; boilerplate no longer attached • Monitoring for total hardness added for all outfalls as monitoring for hardness dependent metals is required • Monitoring for SW018A, SW018B, and Laydown Drainage Area 2 have been removed as the outfalls are now inactive • Benchmark values added for Boron and Mercury Page 12 of 14 • Benchmarks updated for parameters per guidance from DWR Standards group on stormwater benchmarks Section 4. Changes from draft to final: • SWO02 moved from Table 1 to Table 2 per additional information received from permittee • PCB monitoring • SWO14 changed to Drainage Area 14 under "Additional Outfalls" per permittee comments • Laydown Area 2 moved from "Additional Outfalls" to Table 2 per permittee comments Section 5. Discussions with the Facility and Regional Office: • Initial contact with facility made: 11/15/2021 • Draft sent to Regional Office: 1/20/2022 • Submitted for public notice: 2/23/2022 • Final permit sent for supervisor signature: 6/XX/2022 Section 6. Comments received on draft permit: James Moore (DEQ MRO; via email 2/18/22) • Based on the inspection all outfalls in the 2022 renewal are active. With the amount of coal ash being removed and placed in the lined landfill in 2021/2022 it will be interesting comparing analytical results to 2020 later this year. Also I would recommend Tier relief for the outfalls across the river from the switchyard area. Please call if you want to discuss. • Paul Draovitch is no longer the contact person. I would send to Elizabeth Glenn or ask her who is the new business unit head. Elizabeth Glenn (Duke Energy; via email 3/24/22): • Page 9 of 40, B-12: Request that online certification recorded under an employee's ID serve as the required signature. Duke Energy conducts employee training via Computer Based Trainings (CBTs). Access to CBTs are specific to an employee's Duke Energy assigned ID, therefore completion of the training is tracked and logged under the individual's ID. o DEQ response: This is standard language included in all NPDES stormwater individual industrial permits. As long as a list of employees trained can be provided upon request, and the IDs match to specific employees, Duke Energy may use IDs to track employee training. • Page 12 of 40, D-1 (b): Clarification on what equipment is included in the motor oil and hydraulic oil for the facility. Rogers has a multitude of oil -filled equipment contained in the powerhouse. If this equipment were to leak and enter Page 13 of 14 a drain, it would be captured in the station's wastewater system tracked via the NPDES Wastewater permit. o DEQ response: Tracking should be kept for any equipment that utilizes motor oil and hydraulic oil. • Page 13 of 40, Table 1: Clarification on the NCOIL parameter as to if the 55 gallon usage is per drainage area or for the entire facility. As stated in comment 2., the majority of oil at Rogers is contained within the powerhouse and does not pose a stormwater risk. o DEQ response: The reference to 55-gallon usage is meant for the entire site, not just within a specific drainage area. • Page 13 of 40, Table 1: Removal of Outfall SW002 and addition to Table 2. o DEQ response: Based on additional information received, SW002 has been moved from Table 1 to Table 2 as coal ash is present under a layer of gravel in the switchyard. • Page 13 of 40, Polychlorinated biphenyls (PCBs): In previous permits, a footnote was included for PCB sampling providing relief from further sampling if results demonstrate non -detect levels. o DEQ response: As PCBs have the potential to be discharged, monitoring is now required. • Page 15 of 40, Table 2: Laydown Area #2 is not listed. This area consists of an old sediment basin from the construction of Unit 6. The sediment basin was never removed and the riser structure discharges to an unnamed tributary. o DEQ response: Laydown Area #2 has been added to Table 2. • Page 14 & 15 of 40, Table 1 & 2: Mercury footnote absent. The current permit has foot notes that a benchmark exceedance for mercury will not trigger a tier response. Request that this footnote be added. o DEQ response: The policy regarding mercury monitoring has been modified. Mercury is now a required monitoring parameter with an applicable benchmark as it has the potential to be discharged. • Page 17 of 40, Additional Outfalls: Laydown #2 area is not abandoned and SW014 does not exist. o DEQ response: The permit has been amended to reflect Drainage Area 14 and not SW014. Laydown Area #2 has been added to Table 2.

Multiple folks have contributed, so please let me know if some of the response are unclear. Thank you and Happy New Year. J. Elizabeth Glenn Permitting & Compliance Duke Energy, Environmental Services Office: (980) 373 0530 From: Young, Brianna A <Brianna.Young@ncdenr.gov> Sent: Thursday, December 16, 2021 6:19:28 PM To: Glenn, Elizabeth <Elizabeth.Glenn@duke-energy.com> Subject: [EXTERNAL] Questions on Rogers Energy Complex (NCS000571) Good evening Elizabeth, I am reviewing the renewal application for the Rogers Energy Complex (formerly Cliffside) (NCS000571) and had a few questions. Lined basement basin — Is this the 3 large basins constructed that were mentioned in the application as changes since last permit? In addition, the application states a discharge would occur if a significant rainfall event generated enough runoff to overtop the holding pond. However, no outfall coordinates for were provided . Can you provide more information on this potential discharge? The Basement Basin is one of the three basins constructed since the stormwater permit was issued. The three basins discharge thru NPDES Permit NC0005088 - Outfall 005. The emergency overflow is also covered in the NPDES Permit NC0005088 as outfall 002B for the Basement Basin and Outfall 002C for the Holding & Aux Storage Basins. Outfall SWO05 (Drainage Area 5) — information in the permit file states roof drainage from Units 1 through 4 turbine rooms is discharged via French drains, and the renewal application states the discharge has been converted to flow to lined holding cell. Can you confirm where the discharge from this outfall flows or provide more information on flow from Units 1 through 4? The buildings associated with Units 1-4 have been demolished and the basement was converted to the Basement Basin to received stormwater and process water that is discharged thru the NPDES permit NC0005088. The roof drains from Units 1 thru 4 do not exist since the buildings were removed. Part of the French drains still exist and receives stormwater around the water intake structure which is SW005. Outfall SWO06 — Information in the permit file states this outfall was abandoned and the drainage area is largely routed to the yard sump, however the renewal application sates the drainage area sheet flows to the discharge canal. Can you confirm where the discharge from this outfall flows? SWO06 had one inlet grating that drained a small area. Part of this area was filled in with the demolition of Units 1 thru 4 and building the Basement Basin. The discharge pipe was filled with flowable fill. SWO06 drainage area sheet flows to the CCW discharge canal which goes to the Broad River. Landfill Drainage Area —The application states non -contact landfill stormwater is discharged from here. Can you provide any additional information on this? In addition, information in the permit file states stormwater runoff from active cells at the landfill is directed into the leachate collection system, pumped to the leachate collection basin, then to the ash basin; however, this is not stated in the current permit renewal application. Is this process still in place? The landfill at Rogers Energy Complex will be built in 5 phases. Currently, 4 phases have been constructed and 3 phases are receiving Coal Combustion Residual (CCR) material. Phase 4 water is currently considered storm water since it has no contact with CCR material. When CCR will be placed in cell 4, it will be treated as leachate and processed thru NPDES NC0005088 - Outfall 005. To maximize land use, soil is removed from the landfill area during construction and a liner is installed on the side slopes and bottom where the soil was excavated. This creates a containment / barrier for stormwater or CCR contact water (leachate) from ground water. During construction and until stormwater contacts CCR it is treated as non contact stormwater. Once the stormwater contacts CCR it is treated as leachate and is processed thru the NPDES NC0005088. Some of the landfill phases were engineered to have divider cells to separate stormwater within the phases until CCR is placed in the cell to reduce the amount of leachate generated. As the CCR is placed in the landfill, the landfill grows in height. Any stormwater that falls on the outside slope of the landfill is treated as non - contact stormwater since it has not contacted any CCR material. The stormwater that falls on the inside slope of the landfill is treated as leachate since it has contacted CCR material. Once the landfill reaches the engineered height, a liner system will be installed on the top and sides of the landfill in addition to a protective cover material. Once the landfill is completed and covered, all the stormwater will be treated as non -contact stormwater. Stormwater that contacts CCR is treated as leachate. A drainage system in the base of the landfill directs water to a leachate pump system that removes the water from the landfill. The leachate is pumped to a concrete leachate basin and then pumped to Unit 6 process waste water drain system. The water is discharged thru NPDES permit NC0005088 — Outfall 005 after it is treated. A new waste water treatment plant was installed to replace the ash basin Outfall 002. The description should state that the leachate collection basin is pumped to the Unit 6 process drains and discharges thru NPDES NC0005088 Outfall 005.

Brianna — While we are emailing on Cliffside, I wanted to discuss the email chain below. As Sergei stated, the outfall would not be removed from the wastewater permit until the stormwater permit housed the outfall or your department agreed it could be added to the permit. Since it appears you may be working on completing the Cliffside renewal, would now be the best time to pursue this effort? We could submit an update to the permit renewal application to include the proposed SW outfall. Thankyou! J.

The subject permit expires on September 30, 2020. Section III Part B of this permit requires the permit application for permit renewal to be submitted at least 180 days prior to the expiration date of the permit. Attached is the renewal application form and duplicate copies of the supplemental information. It is requested that the monitoring frequency for SWO01 and SWO04 be reduced to semi-annual. These two outfalls receive rainwater from switchyards. Historically the monthly sampling is above the benchmark level for zinc. Measures have been put in place to remove zinc using absorbent material, but due to the galvanized metal within the switchyards the stormwater monitoring levels are still above the benchmark levels.

There are no industrial activities associated with outfalls SW008, SW010, SW019 and the Unit 6 switchyard. 4. The haul road to the ash landfill was paved. 5. Three large basins were constructed that collect wastewater and stormwater. One basin (Basement Basin) was built in the footprint of the demolished Unit 1-4 power station. This basin collects stormwater run-off from Unit 5 and 6. The stormwater collected in the Basement Basin is pumped to the Auxiliary Basin for processing in the site wastewater treatment system (NPDES permitted outfall 005). Two other basins (Holding Basin and Auxiliary Basin) were constructed in the Unit 1-4 retired ash basin after all ash was removed from this ash basin. The Holding Basin receives stormwater run-off from the coal, limestone and gypsum piles. This water is processed in the wastewater treatment system.

Send all suspicious email as an attachment to Matt, The Industrial Storm Water Permit NCS000571 for Rogers Energy Complex requires the following: "Should the permittee identify or create any new stormwater outfalls; remove any stormwater outfalls identified in this permit; or alter any drainage areas that change the potential pollutants in runoff discharged through corresponding outfalls, the permittee will submit a request to NC DEMLR to modify this permit." At Rogers Energy Complex the storm water discharge pipe SWO12 was in place for a previous sediment basin. With the site now being stable this outfall was recently modified to incorporate a rock pathway versus a standpipe leaving the basin. Outfall SWO12 still exists but just wanted to inform you that the actual discharge structure has been modified. Within the next month or two (October or November 2020 timeframe) plans are to remove two storm water pipes (SW018A and SW018B). These discharge pipes are being removed as part of the ash storage area closure activity. Please advise if you need any additional information.

Aana, To follow-up with you and James on the note below I wanted to let you know at Rogers Energy Complex storm water outfalls SWO18A and SWO18B were physically removed on December 2, 2020. This notification is being made as required in Section B of the subject permit where it states: "Should the permittee identify or create any new stormwater outfalls; remove any stormwater outfalls identified in this permit; or alter any drainage areas that change the potential pollutants in runoff discharged through corresponding outfalls, the permittee will submit a request to NC DEMLR to modify this permit." This permit is in the renewal process so it is preferred to capture this change as part of the permit renewal instead of modifying the current permit.
