All plant waste streams are routed directly or indirectly to the Hyco Reservoir. Chemical constituents contained in these discharges will, in part, be representative of the naturally occurring chemical quality and quantity of the intake water and will also have chemical constituents of such quality associated with similar discharges for fossil generating facilities of this size, type, and in this geographical location. Either all or part of the elements in the Periodic Table, either singularly or in any combination, may from time to time be contained in the discharges. Each component of the discharges is described below. Outtall 003 — Effluent Channel At the point that the effluent channel enters the Hyco Reservoir, it contains the flows from several waste streams, including once -through cooling water, stormwater runoff, and the effluent from the ash pond, which in turn receives and treats combined flows from the ash transport system, the low volume waste system, the dry fly ash handling system, cooling tower blow down, stormwater runoff, drainage from the ash landfill, east ash pond, various seepage flows and from occasional wastewater piping leakage. Once -Through Cooling Water Condenser Cooling Water (CCW) for Units 1, 2, and 3 is drawn from the Hyco Reservoir via an intake canal and discharges to the Hyco Reservoir via a effluent channel. Flows for Units 1, 2, and 3 are 249 MGD, 342 MGD, and 505 MGD respectively. Cooling is accomplished by evaporation from the surface of cooling water in the effluent channel, cooling towers, mixing and convection with Hyco reservoir waters. October 2014 Page 1 Wk 10 During the summer months, Unit 3 CCW is routed through mechanical draft cooling towers where most of the waste heat is removed by evaporation before the water is discharged to the reservoir via the effluent channel along with the CCW of Units 1 and 2. Additionally, once -through cooling water is used for heat exchange of component closed cooling water, the flow of which is combined with the CCW prior to introduction into the effluent channel. Stormwater Runoff The stormwater, which flows into the discharge canal includes runoff from the plant drainage area, the drainage area from the dry fly ash handling system (including roadways), Unit 4 cooling tower drainage area, the fuel oil storage containment area, the switchyard drainage area, the anhydrous ammonia tank farm, and the gypsum storage pile area. Ash Pond Discharge :%17nferpta etj- )WQ 60 a The ash pond receives ash transport water, low volume wastes, runoff from the ash landfill, landfill leachate, dry fly ash handling system wash water, blow down from Unit 4 cooling tower, coal mill rejects and pyrites, and sewage treatment plant effluent. The pond provides treatment by sedimentation, oxidation, neutralization, equalization, adsorption and chemical precipitation. The following flows are routed to the ash pond treatment system: 1. Ash Transport Water Water for sluicing ash to the ash pond is withdrawn from the CCW system as needed. The plant will primarily supply ash sluice water from Unit 2. However, the facility will continue to maintain the ability to operate the unit 4 ash sluice pumps. The Unit 4 ash sluice pumps are and will continue to be utilized for the following i) during maintenance draining of the cooling tower, ii) back-up supply for the fire suppressant system, and iii) ash October 2014 Page 2 sluicing pumps during operational events which require additional pumping. Normally, only bottom ash is conveyed to the ash pond by sluicing. Fly ash is handled dry by a pneumatic system and is land filled on site or sold. If the dry fly ash handling system is out of service during plant operating periods, fly ash will be sent to the ash pond via the ash sluicing systems until the dry system is restored. Such occurrences are expected to be infrequent and brief. 2. Silo Wash Water Ash silo wash water runoff, stormwater from around the ash silos and dust suppressant spray runoff from the dry fly ash handling system are routed to the ash pond. 3. Low Volume Wastes Boiler make-up water is withdrawn from the intake and filtered, softened, and de-mineralizered for treatment. This process includes treatment via a process water reverse osmosis system. Boiler water is treated with ammonia, hydrazine, phosphate and occasionally sodium hydroxide. Boiler blow down is sent to the ash pond via the low volume wastes collection system (LVWS). These are special drains in the plant that flow by gravity to collection sumps and are pumped to the ash pond. Ethylene glycol is used for freeze protection of some equipment and may be discharged to the LVWS, as is some molybdate waste from the closed cooling water system, during periods of maintenance. When this equipment is rinsed, small amounts of these chemicals are discharged to the low volume system via the neutralization basin. The plant's Reverse Osmosis system produces a reject wastestream of approximately 250 gpm, when in operation. Essentially all plant equipment, floor drains, water treatment filter backwashes, clarifier and sedimentation basin sludge, and ash hopper seal water overflow also discharge to the LVWS. Plant drains around oil containing equipment are routed to an oil/water October 2014 Page 3 separator for treatment prior to being sent to the ash pond via the LVWS. Various boiler sediments and ash accumulations collected during maintenance activities may also be transported to the ash pond or the onsite ash landfill. Seepage through the ash pond dam may be released to the effluent channel. 4. Cooling Tower Blow down Unit 4 is the only unit that produces cooling tower blow down. A blow - \\7 down stream is used to maintain concentrations of total dissolved solids in the cooling tower to within proper operating limits. Make-up to the Unit 4 cooling tower is from the Heated Water Discharge Canal. p 5. Domestic Sewage kooT Domestic sewage is treated by an extended aeration treatment plant �N tYr consisting of a screen, comminutor, surge tank, aeration tank, clarifier, chlorine contact chamber, and a sludge holding tank. 6. Air Preheater Cleaning (Low Volume Waste The air preheater will be water washed once per year or more frequently as needed. The wastewater from this activity will be discharged to the ash pond. 7. Chemical Metal Cleaning Wastes The boilers are chemically cleaned approximately every five -to -eight years as required using Tetraammonia ethylene diamine tetraaccetic acid (EDTA) solution or citric acid. This cleaning solution and its rinses are stored on site for disposal by evaporation in an operating unit's furnace. Should evaporation not be used, the wastewater can be treated by neutralization and precipitation prior to being conveyed to the ash pond. October 2014 Page 4 l Alternatively, the wastewater can be disposed by other acceptable disposal methods. Cleaning of other heat exchanger surfaces may produce 5,000-10,000 gallons of wastewater approximately every three -to - five years. 8. Flue Gas Desulfurization Blow down (Low Volume Waste) The Flue Gas Desulfurization (FGD) system directs flue gas into an absorber where limestone (calcium carbonate) slurry is sprayed. Sulfur �uv dioxide in the flue gas reacts with the limestone slurry to produce calcium �( sulfate (gypsum). The system reclaims any un-reacted limestone slurry to be reused in the absorber. A small blowdown stream is used to maintain the chloride concentration in the reaction tank. The blowdown stream is discharged to a gypsum settling pond where suspended solids are settled out prior to entering a bioreactor. The bioreactor utilizes microbes to reduce targeted soluble contaminants to insoluble forms that then precipitate from solution. The treated wastewater enters the ash pond effluent channel prior to outfall 002. 9. Flue Gas Desulfurization (FGD) System Blow down Emergency Overflow/Pipeline Drain Emergency overflow from the FGD System blow down will discharge to the ash pond. If the FGD System blow down pipeline requires emergency draining, the contents of the pipeline will be drained to a sump that is pumped to the ash pond. 10. Ash Landfill Drainage Water for sluicing a minimum amount of bottom ash to the ash landfill is withdrawn from the ash transport system as needed. The bottom ash is used to enhance the subsurface drainage of the landfill. October 2014 Page 5 The facility may transfer settled ash from the west ash pond to fill remaining capacity in the east ash pond as needed. This activity may be undertaken to provide treatment capacity (i.e. volume) in the active, west ash pond and or in preparation for landfill expansion in accordance with permits issued through the NC Division of Solid Waste. 11. Stormwater Runoff The stormwater runoff, which flows into the ash pond includes runoff from the plant drainage area, landfill runoff (including silo area drainage), and the drainage area from the ash pond (including roadways). 12. Seepage Small seepage flows through engineered drainage features in the ash basin dam and other points on the property comingle with the ash pond discharge and cooling water discharge. Outfall 006 — Coal Pile Runoff Runoff from the coal pile, limestone pile, small potential gypsum pile on the west side of the plant, truck wheel wash and other coal handling areas of the plant is routed to a retention pond for treatment by neutralization, sedimentation, and equalization. The pond is designed to store in excess of the 10-year/24-hour storm event. Releases are controlled by a standpipe structure. Approximately 0.006 MGD of wheel wash water will be sent via gravity drain to a solids settling basin. Solids from the wheel wash will accumulate in a separate settling basin to be removed by front end loaders and sent to the onsite landfill. Water from the settling basin will go to outfall 006. Stormwater from the FGD and Fuel Handling maintenance area located west of the coal pile flows to the coal pile runoff pond.

The evaluation included a detailed site reconnaissance to identify potential seeps followed by the collection of flow measurements and representative water quality samples at select locations. The site reconnaissance was conducted during March 2014. Representative seep locations were evaluated for water quality and flow rates on August 25 and 26, 2014. Wastewater discharges from the ash basins are permitted by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Resources (DWR) under National Pollution Discharge Elimination System (NPDES) Permit NC0003425. The purpose of the evaluation was to determine additional potential outfalls for inclusion within the permit. Eleven seep locations were originally identified during wet weather conditions in early spring of 2014. However, of those 11 identified seeps, only six locations contained sufficient water for water quality sample collection in August 2014. Three additional seeps were sampled in August 2014. Eight of the seeps are located upstream of NPDES Outfall 003 to Hyco Lake. The remainder of the seeps are located upstream of the intake canal. The low volume of water characteristic of the seeps coupled with the relatively low constituent concentrations in the samples, suggest that the seeps have little potential to influence water quality of Hyco Lake. The combined flow of all measured seeps is 0.03 million gallons per day. The typical NPDES wastewater flow for the Roxboro Plant is 1.07 billion gallons per day. If reasonable analyses demonstrate that the seeps have no potential to exceed water quality standards, then Duke Energy proposes to re-evaluate the seep locations listed in this document annually over the next 5-year permit cycle. These annual evaluations would be documented and would verify the condition of the existing seeps and determine the presence of new seeps. DWR will be promptly notified if any new seeps are identified or any significant changes are observed for the existing seeps. If any existing or newly identified seeps are determined to reach Hyco Lake and the seepage has reasonable potential to exceed a water quality standard, Duke Energy will take measures to either (1) stop the seepage, (2) capture and route the seep so that it is discharged through a NPDES permitted outfall, or (3) address the seep using Best Management Plans approved by DWR.

A large part of the Plant area encompasses Hyco Lake. The Roxboro Plant is located in Person County along the east bank of Hyco Lake north of Roxboro, NC and west of McGhees Mill Road. The site location is shown on Figure 1. The Roxboro Plant began operations in 1966. Additional units were added in 1968, 1973, and 1980. Throughout its operational history, the Roxboro Plant has employed coal-fired units to produce steam. Ash generated from coal combustion is stored on -site in ash basins (the 1966 semi -active East Ash Basin and the 1973 active West Ash Basin). Wastewater discharges from the ash basins are permitted by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Resources (DWR) under National Pollution Discharge Elimination System (NPDES) Permit NC0003425. This report summarizes an evaluation of seepage flows from the Roxboro Plant ash basins. The evaluation included a detailed site reconnaissance to identify potential seeps, flow measurements of identified seeps, and collection of seep water and other surface water with chemical analysis of collected samples. The site reconnaissance was conducted in March 2014. Seep sampling and flow measurements were completed on August 25 and 26, 2014.

Identified seeps were described, photographed, noted on a field map, and surveyed as to location using GPS (Table 1). Identified seeps were further evaluated on August 25 and 26, 2014. During the August evaluation, it was observed that some of the seeps identified during the initial reconnaissance were dry, reflecting an intermittent or seasonal nature. The locations of seeps identified are presented on Figure 2. 2.2 Seep Flow Measurement Flow measurements were made in August 2014 at water -bearing seep locations using either a Son-Tek F1owTracker M Acoustic Doppler Velocimeter or the timed -volumetric method. The F1owTracker® measures stream velocity and discharge using sound waves. The timed -volumetric method was used at six locations where the flow was constrained in a location that prevented the F1owTracker® from recording a signal without interference. One location did not have sufficient flow to measure a flow rate. The timed -volumetric method was employed by collecting a volume of water from the flow of the seep directly into an appropriately sized container (graduated cylinder or bucket). The entire seep flow was routed to the container. The amount of time (in seconds) required to collect a known volume of water was recorded. A minimum of five timed volumes were recorded and the flow rate for the seep was calculated based on an average of the timed volume measurements. The F1owTracker® was used to measure seep flows at two locations. The method is designed for streams that can be waded following established procedures such as the U.S. Geological Survey standards. Use of the F1owTrackerO was generally limited to channels of sufficient width (approximately 0.5 feet or greater) and depth (approximately 0.17 feet or greater). Flow measurements (water velocity and depth) within quality control bounds of the instrument were recorded manually for estimation of discharge at a seep. Locations were selected where channel banks were fairly parallel. The channel width was measured at the water line and recorded. If the charmel width was less than one foot, the average depth was recorded and three velocity measurements were taken. The average of the three velocity measurements and the channel volume (depth and width) were used to calculate the flow rate at a given location.

If the channel width was between 2.5 and 5 feet, velocity and depth were recorded at a minimum of five evenly spaced locations. Consistent with USGS methodology, velocity measurements were collected at 60% of water depth. The averages of the calculated flows (in MGD) for seeps with measurable flow in August 2014 are included in Table 2. Seepage flow is generally variable. Flow may increase or decrease depending on the amount of rainfall, groundwater levels, weather conditions, and other variables. 2.3 Seep Sample Collection Eight locations with sufficient water for sample recovery were sampled during August 2014 for water quality analysis. The sample locations are described in Table 1 and shown on Figure 2. To prevent dilution from stormwater runoff into seep flows, seep samples were collected during a period preceded by low precipitation. For the week preceding the August sample collection, 0.37 inches of rain fell in the area as recorded at the Person County Airport (Roxboro, NC), located about ten miles south-southeast of the Roxboro Plant. Samples were collected from the seep flows directly into sample containers. Care was taken to avoid disturbing and entraining particulate soil and sediment. During sample collection, in -situ field parameters (temperature, pH, and specific conductance) were measured utilizing a YSI Pro Plus multi -function meter. Turbidity was also measured in the field using a Hach 2100Q turbidimeter. Laboratory analyses were conducted by Duke Energy Analytical Laboratory and Pace Analytical Laboratories (NC Wastewater Certifications #248 and 12). A summary of the laboratory and field data is provided in Table 2. A listing of analytical parameters and associated methods are included in Table 3. Sample handling, storage, and preservation methods are summarized in Appendix A.

If ongoing analyses demonstrates that there is no potential to exceed water quality standards, Duke Energy proposes to re-evaluate the identified seep locations listed in this document annually over the next five-year permit cycle. These annual evaluations would be documented and would verify the condition of the existing seeps and determine the presence of any newly developed seeps. DWR will be promptly notified if new seeps are identified or any significant changes are observed for the existing seeps. If any existing or newly identified seeps are determined to reach Hyco Lake and the seepage has reasonable potential to exceed a water quality standard, Duke Energy will take measures to either (1) stop the seepage, (2) capture and route the seep so that it is discharged through a NPDES permitted outfall, or (3) address the seep using Best Management Plans approved by DWR.

Enclosed with this letter are the results of the water quality sampling. The boron result suggests that the water is influenced by coal combustion residuals, however, the exact source is unknown. The water of this AOW emerges from under the sluice lines, flows along the sluice lines, and enters a gully whose water flows into Roxboro's heated water mixing zone north of the ash basin.

'Except where noted in this Table II and the method for the parameter, preserve each grab sample within 15 minutes of collection. For a composite sample collected with an automated sample (e.g., using a 24-hour composite sample; see 40 CFR 122.21(g)(7)(i) or 40 CFR Part 403, Appendix E), refrigerate the sample at 56 °C during collection unless specified otherwise in this Table II or in the method(s). For a composite sample to be split into separate aliquots for preservation and/or analysis, maintain the sample at 56 °C, unless specified otherwise in this Table II or in the method(s), until collection, splitting, and preservation is completed. Add the preservative to the sample container prior to sample collection when the preservative will not compromise the integrity of a grab sample, a composite sample, or aliquot split from a composite sample within 15 minutes of collection. If a composite measurement is required but a composite sample would compromise sample integrity, individual grab samples must be collected at prescribed time intervals (e.g.. 4 samples over the course of a day, at 6-hour Intervals). Grab samples must be analyzed separately and the concentrations averaged. Alternatively, grab samples may be collected in the field and composited In the laboratory if the compositing procedure produces results equivalent to results produced by arithmetic averaging of results of analysis of Individual grab samples. For examples of laboratory compos Ping procedures, see EPA Method 1664 Rev. A (oil and grease) and the procedures at 4O CFR 141,34(f)(14Xiv) and (v) (volatile organics), 'When any sample is to be shipped by common carrier or sent via the U.S. Postal Service, it must comply with the Department of Transportation Hazardous Materials Regulations (49 CFR part 172). The person offering such material for transportation, is responsible for ensuring such compliance. For the preservation requirement of Table II, the Office of Hazardous Materials, Materials Transportation Bureau, Department of Transportation has determined that the Hazardous Materials Regulations do not apply to the following materials: Hydrochloric acid (HCI) In water solutions at concentrations of 0.04% by weight or less (pH about 1.96 or greater; Nllde acid (HNO3) In water solutions at concentrations of 0.15% by weight or less (pH about 1.62 or greater); Sulfuric acid (H2SO4) in water solutions at concentrations of 0.35% by weight or less (pH about 1.15 or greater); and Sodium hydroxide (NaOH) in water solutions at wncentralons of 0.080% by weight or less (pH about 12.30 or less), 'Samples should be analyzed as soon as possible after collection. The times listed are the maximum times that samples may be held before the start of analysis and still be considered valid. Samples may be held for longer periods only if the permittee or monitoring laboratory has data on file to show that, for the speck types of samples under study, the analyzes are stable for the longer time, and has received a variance from the Regional Administrator under Sec. 136.3(e). For a grab sample, the holding time begins at the time of collection. For a composite sample collected with an automated sampler (e.g., using a 24-hour composite sampler, see 40 CFR 122.21(g)(7)(i) or 40 CFR part 403, Appendix E), the holding time begins at the lime of the end of collection of the composite sample. For a set of grab samples composited in the field or laboratory, the holding time begins at the time of collection of the last grab sample In the set. Some samples may not be stable for the maximum tine period given in the table. A permittee or monitoring laboratory is obligated to hold the sample for a shorter time if it knows that a shorter lime is necessary to maintain sample stability. See 136.3(e) for details. The date and time of collection of an Individual grab sample Is the date and time at which the sample is collected. For a set of grab samples to be composited, and that are all collected on the same calendar date, the date of collection is the date on which the samples are collected, For a set of grab samples to be composited, and [hat are collected across two calendar dates, the date of collection is the dates of the two days; e.g., November 14-15. For a composite sample collected automatically on a given dale, the dale of collection is the date on which the sample Is collected. For a composite sample collected aulomatically, and that is collected across iHro calendar dates, the dale of collection is the dates of the two days;. e.g., November 14- 15. For static -renewal toxicity tests, each grab or composite sample may also be used to prepare test solutions for renewal at 24 h. 48 h, and/or 72 h after first use, if stored at 0-6 °C, with minimum head space. °ASTM O7365-09a specifies treatment options for samples containing oxidants (e.g., chlorine). Also, Section 9O60A of Standard Methods for the Examination of Water and Wastewater (2011h and 21st editions) addresses dechtorination procedures. 'Sampling, preservation and mitigating Interferences in water samples for analysis of cyanide are described in ASTM D7365-09a. There may be inlerfererres that are not mitigated by the analytical lest methods or D7365-09a. Any technique for removal or suppression of interference may be employed, provided the laboratory demonstrates that it more accurately measures cyanide through quality control measures described in the analytical test method. Any removal or suppression technique not described in D7365-09a or the analytical test method must be documented along with supporting data. 'For dissolved metals, filter grab samples within 15 minutes of collection and before adding preservatives. For a composite sample collected with an automated sampler (e.g., using a 24-hour composite sampler, see 40 CFR 122.21(g)(7)(i) or 40 CFR Pad 403. Appendix E), filter the sample within 15 minutes after completion of collection and before adding preservatives. If 0 is known or suspected that dissolved sample integrity will be compromised during collection of a composite sample collected automatically over time (e-g., by interchange of a metal between dissolved and suspended forms), collect and fitter grab samples to be composited (footnote 2) in place of a composite sample collected automatically. 'Guidance applies to samples to be analyzed by GC. LC, or GCIMS for specific compounds. 'If the sample is not adjusted to pH 2. then the sample must be analyzed within seven days of sampling. ""The pH adjustment is not required If acrolein will not be measured. Samples for acroleln receiving no pH adjustment must be analyzed within 3 days of sampling. "When the extractable analytes of concern fall within a single chemical category, the specified preservative and maximum holding times should be observed for optimum safeguard of sample Integrity (i.e., use all necassary preservatives and hold for the shortest time listed). When the analytes of wncem fall within two or more chemical categodes, the sample may be preserved by cooling to 56 *C. reducing residual chlorine with O,008'% sodium thiosulfate, storing in the dark, and adjusting the pH to 6-9; samples preserved in this manner may be held for seven days before extraction and for forty days after extraction. Exceptions to this optional preservation and holding time procedure are noted in footnote 5 (regarding the requirement for thiosuffale reduction), and footnotes 12, 13 (regarding the analysis of benzidine). *if 1,2-0iphenyihydrazine is likely to be present adjust the pH of the sample to 4.0 t02 to prevent rearrangement to benzidine. "ExImcts may be stored up to 30 days at <0'C. "For the analysis of diphenylnilrosamine, add 0.008% Na232O3 and adjust pH to 7-10 with NaOH within 24 hours of sampling. 'The pH adjustment may be performed upon receipt at the laboratory and may be omitted if the samples are extracted Within 72 hours of collection. For the analysis of aldrin, add 0.008% NarSrOa. "Place sufficient ice with the samples in the shipping container to ensure Thal ice is still present when the samples arrive at the laboratory. However, even if ice is present when the samples arrive, immediately measure the temperature of the samples and confirm that the preservation temperature maximum has not been exceeded. In the Isolated cases where It can be documented that this holding temperature cannot be met, the permittee can be given the option of on -rile testing or can request a variance. The request for a variance should include supportive data which show that the toxicity of the effluent samples is not reduced because of the increased holding temperature.. Aqueous samples must not be frozen. Hand-dellvered samples used on the day of collection do not need to be cooled to 0 to 6 °C prior to test initiation. "Samples collected for the determination of trace level mercury (<100 nglL) using EPA Method 1631 must be collected in tightly - capped fluoropolymer or glass bottles and preserved with BrCI or HCI solution within 48 hours of sample collection. The lime to preservallon may be extended to 28 days if a sample is oxidized in the sample bottle. A sample collected for dissolved trace level mercury should be filtered in the laboratory within 24 hours of the time of collection. However, if circumstances preclude overnight shipment, the sample should be filtered in a designated clean area in the field in accordance with procedures given in Method 1669. If sample Integrity will not be maintained by shipment to and filtration in the laboratory, the sample must be filtered in a designated clean area in the field within the lime Period necessary to maintain sample integrity. A sample that has been collected for determination of total or dissolved trace level mercury must be analyzed within 90 days of sample collection. "Aqueous samples must be preserved at s6 tC, and should not be frozen unless data demonstrating that sample freezing does not adversely Impact sample Integrity Is maintained on file and accepted as valid by the regulatory authority. Also, for purposes or NPDES monitoring, the specification of "s°C" is used in place of the'4 °C' and'<.4 °C' sample temperature requirements listed in some methods. It is not necessary to measure the sample temperature to three significant figures (1/100th of 1 degree); rather, three significant figures are specked so that rounding down to 6'C may not be used to meet the s6'C requirement. The preservation temperature does not apply to samples that are analyzed immediately (less than 15 minutes). tBAn aqueous sample may be collected and shipped without acid preservation. However. acid must be added at least 24 hours before analysis to dissolve any metals that adsorb to the container walls. If the sample must be analyzed within 24 hours of collection, add the acid immediately (see faMnote 2). Soil and sediment samples do not need to be preserved with acid. The allowances In this footnote supersede the preservation and holding time requirements in the approved metals methods. ' ro achieve the 28-day holding time, use the ammonium sulfate buffer solution specified in EPA Method 218.6. The allowance in [his footnote supersedes preservation and holding time requirements in the approved hexavalent chromium methods, unless this supersession would compromise the measurement, in which case requirements In the method must be followed. "Holding time is calculated from time of sample collection to elution for samples shipped to the laboratory in bulk and calculated from the time of sample'iltration to elution for samples filtered in the field.

(Duke Energy) requirement for groundwater monitoring around the Roxboro Steam Plant (Roxboro Plant) ash management area operated under NPDES Permit NC0003425. This Plan describes the groundwater monitoring network, methodologies of field sampling, record -keeping protocols, analytical procedures, data quality objectives, data validation, and reporting that will be used for the Roxboro Plant ash basins groundwater monitoring program.

A large part of the Plant area encompasses Hyco Lake. The Roxboro Plant is located in Person County along the east bank of Hyco Lake north of Roxboro, NC and west of McGhees Mill Road. The site location is shown on Figure 1. The Roxboro Plant began operations in 1966, and additional units were added in 1968, 1973, and 1980. Throughout its operational history, the Roxboro Plant has employed coal-fired units to produce steam. Coal combustion residuals (CCR) have been managed in on -site ash basins. 2.2 Ash Management Area Description Ash generated from coal combustion throughout the operational history of the Roxboro Plant was stored in on -site ash basins and a CCR landfill. Throughout most of its history, ash was sluiced as a slurry to the ash basins or conveyed in its dry form to the CCR landfill. Two ash basins have historically been used at the Roxboro Plant and are referenced using the date of construction and relative location: the 1966 ash basin (East Ash Basin) and the 1973 active ash basin (West Ash Basin). The 1966 semi -active ash basin is located southeast of the plant, and the 1973 active ash basin is located south of the plant. The CCR landfill was constructed as an unlined landfill on top of the former East Ash Basin in 1988. A lined landfill was subsequently constructed over the unlined landfill in 2004. The ash basins are impounded by earthen dams. Surface water runoff from the East Ash Basin and the CCR landfill are routed into the West Ash Basin to allow settling. - A 500-foot compliance boundary encircles the ash basin areas. The ash basin locations are indicated on Figure 2. Currently, the East Ash Basin and CCR landfill are covered with vegetation where the landfill is not active (grasses and shrubs). The active ash basin has some grass cover and ponded water, mostly along the southern and eastern edges of the basin. Wastewater discharges from the facility are permitted by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Resources (DWR) under National Pollution Discharge Elimination System (NPDES) Permit NC0003425. Page 2 P:\Duke Energy Progress.1026\ALL NC SITES\NPDES Permit Deliverables\Roxboro\Gw Monitoring Plan\Roxboro GW Monitoring Plan.dooc Groundwater Monitoring Program October 2014 oxboro Steam Plant, NPDES Permit # NC0003425 SynTerra 3.0 SITE GEOLOGY AND HYDROGEOLOGY 3.1 Geologic Framework The Roxboro Plant is situated in the eastern Piedmont Region of north -central North Carolina. The Piedmont is characterized by well-rounded hills and rolling ridges cut by small streams and drainages. Elevations in the area of the Roxboro Plant range between 410 feet above mean sea level (msl) during full pool at Hyco Lake to 570 feet msl near the Dunnaway Road and McGhees Mill Road intersection southeast of the Plant. Geologically, the Plant is located at the contact of two regional geologic zones: the Inner Piedmont zone and the Carolina zone: Both zones are generally comprised of igneous and metamorphosed igneous and sedimentary rocks of Paleozoic age. In general, the rocks are highly fractured and folded and have been subjected to long periods of physical and chemical weathering. The origination, genesis, and characteristics of the rocks of the region have been the focus of detailed study by researchers for many years. These investigations have resulted in a number of interpretations and periodic refinements to the overall geological model of the region. Rocks of the region, except where exposed in road cuts, stream channels, and steep hillsides, are covered with unconsolidated material formed from the in -situ chemical and physical breakdown of the bedrock. This unconsolidated material is referred to as saprolite or residuum. Direct observations at the Roxboro Plant confirm the presence of residuum, developed above the bedrock, which is generally 10 to 30 feet thick. The residuum extends from the ground surface (soil zones) downward, transitioning through a zone comprised of unconsolidated silt and sand, downward through a transition zone of partially weathered rock in a silt/sand matrix, down to the contact with competent bedrock. The Geologic Map of North Carolina (1985) places the rocks of the Plant area in the Charlotte Terrane: a belt of metamorphic rock trending generally southwest to northeast characterized by strongly foliated felsic mica gneiss and schist and metamorphosed intrusive rocks. The rocks of the area near the Plant are described as biotite gneiss and schist with abundant potassic feldspar and gamet, and interlayered and gradational with calc-silicate rock, silliminite-mica schist and amphibolite. The gneiss contains small masses of granite rock. The felsic mica gneiss of the Charlotte Terrane is described as being interlayered with biotite and homblende schist. Later mapping generally confirms these observations and places the Roxboro Plant directly at the contact between the Inner Piedmont zone, characterized by the presence of biotite Page P:\Duke Energy Progress.1 026 \ ALL NC SITES \NPDES Permit Deliverables \ Roxboro \ GW Monitoring Plan \Roxboro GW Monitoring Plan.docc Groundwater Monitoring Program October 2014 oxboro Steam Plant, NPDES Permit # NC0003425 SynTerra gneiss and schist, and the Charlotte Belt (or Charlotte Terrane), characterized by felsic mica gneiss (USGS, 2007). Other researchers have conducted detailed investigations of the area and have provided additional description of the geology in detailed tectonic, structural, and litho- stratigraphic terms (Wilkins, Shell and Hibbard, 1995; Hibbard, et. al., 2002). One of the most important interpretations concerning the geologic nature of the region is the discovery and description of the Hyco shear zone, a tectonic boundary comprised of a ductile shear zone that sharply separates contrasting rocks of the Charlotte (Milton) and Carolina Terranes in north -central North Carolina and southern Virginia (Hibbard, et. a1.,1998). The Hyco shear zone was mapped as directly underlying Hyco Lake. These general geologic observations are consistent with site -specific observations from well logs for the Roxboro Plant, which document the bedrock of the northwestern portion of the compliance boundary as mafic granitic gneiss and the remainder of the site as felsic gneiss and hornblende gneiss. Based on previous activities at the site, subsurface lithology beneath the Plant area is comprised of tan to olive brown sandy silt and fine to coarse sands grading into partially weathered rock and then competent bedrock. 3.2 Hydrogeologic Framework Groundwater within the area exists under unconfined, or water table, conditions within the residuum and/or saprolite zone and in fractures and joints of the underlying bedrock. The water table and bedrock aquifers are interconnected. The residuum acts as a reservoir for supplying groundwater to the fractures and joints in the bedrock. Shallow groundwater generally flows from local recharge zones in topographically high areas, such as ridges, toward groundwater discharge zones, such as stream valleys. Ridge and topographic high areas serve as groundwater recharge zones, and groundwater flow patterns in recharge areas tend to develop a somewhat radial pattern from the center of the recharge area outward toward the discharge areas and are expected to mimic surface topography. The Roxboro Plant is bordered to the west, south, and east by areas of topographic highs. The surface water flow direction for the plant is to the north toward Hyco Lake. Groundwater beneath the Plant area occurs within the residuum/partially weathered rock or competent bedrock at depths ranging from three to 20 feet below land surface (bls) along the downgradient compliance boundary and greater than 35 feet bls upgradient of the ash basin. Routine water level measurements and corresponding elevations from the compliance monitoring well network indicate that groundwater generally flows from upland areas along the south, west, and eastern boundaries Page 4 P:\Duke Energy Progress.1026\ALL NC SITES\NPDESPermit Deliverables \ Roxboro\ GW Monitoring Plan \Roxboro GW Monitoring Plan.docx Groundwater Monitoring Program October 2014 ` oxboro Steam Plant, NPDES Permit A NC0003425 SynTerra towards the north and Hyco Lake. Groundwater generally flows from the south to the north along the western portion of the property and from the southwest to the northeast across the remainder of the property. The approximate groundwater gradient along the western portion of the property for July 2014 data was 85.04 feet (vertical change) over 530 feet (horizontal distance) or 16 feet/100 feet as measured from upgradient background well BG-1 to downgradient well CW-2. The approximate groundwater gradient along the northern compliance boundary for July 2014 was slightly less at 76.64 feet (vertical change) over 570 feet (horizontal distance) or 13.4 feet over 100 feet as measured from well CW-1 to downgradient well CW-2. Groundwater elevation data collected from the two well pairs indicate the vertical gradient tends to be upward or neutral between the transition zone and upper bedrock.

The Roxboro Plant operates under NPDES Permit NC0003425 which authorizes discharge as follows: Ash Basin Treatment System (Internal Outfall 002):, To treat ash transport, low volume wastewater including Reverse -Osmosis (RO) wastewater, runoff from the ash landfill, dry fly -ash handling system wash water, coal pile runoff silo wash water, storm water runoff, cooling tower blowdown from unit number 4, and domestic sewage treatment plant effluent. Effluent from the ash basin discharges to the heated water discharge canal and is ultimately released into Hyco Lake through Outfall 003. • Heated Water Discharge Canal System (Outfall 0031 At the point that the discharge canal enters Hyco Lake, it contains flow from several waste streams including: once -through cooling water, stormwater runoff, and the effluent from the ash basin (Internal Outfall 002). Cooling Tower Blowdown System (Internal Outfall 005): Cooling tower blowdown from unit number 4 discharges into the ash transport system and ultimately flows into the ash basin (Internal Outfall 002). Coal Pile Runoff Treatment System (Outfall 006): This system handles runoff from the coal pile and other coal handling areas including the limestone and gypsum piles and the truck wheel wash water. These waters are routed to a retention basin for treatment by neutralization, sedimentation, and equalization prior to being discharged directly to Hyco Lake. Domestic Wastewater Treatment System (Internal Outfall 008):_ Effluent from the treatment system flows into the ash basin. Effluent from the ash basin discharges into the heated water discharge canal. Chemical Metal Cleaning Treatment System (Internal Outfall 009) This waste stream may occasionally be discharged to the ash basin treatment system. It contains chemical metal cleaning wastes. Effluent from the ash basin discharges into the heated water discharge canal.

After treatment in the bioreactors, effluent is discharged into the heated water discharge canal upstream from Internal Outfall 002, and is ultimately released into Hyco Lake through Outfall 003. In addition to surface water monitoring, the NPDES permit requires groundwater monitoring. Permit Condition A (6) Attachment XX, dated March 17, 2011, lists the groundwater monitoring wells to be sampled, the parameters and constituents to be measured and analyzed, and the requirements for sampling frequency and results reporting. Attachment XX also provides requirements for well location and well construction. The as -built well information is summarized in Table 1 and the constituent list, analytical methods, preservatives and holding times are summarized in Table 2. The well logs for the listed wells are provided in Appendix A. A copy of Attachment XX is included as Appendix B. The compliance boundary for groundwater quality associated with the Roxboro Plant ash basins is defined in accordance with 15A NCAC 02L .0107(a) as being established at either 500 feet from the waste boundary or at the property boundary, whichever is closer to the source. In accordance with the March 17, 2011 Groundwater Monitoring Plan, analytical results have been submitted to the Department of Water Resources (DWR) before the last day of the month following the date of sampling. In the future, analytical results will be submitted to the DWR within 60 days of the date of sampling. 4.2 Description of Groundwater Monitoring System The current NI'DES groundwater monitoring plan for the Roxboro Plant includes the sampling of eight wells surrounding the active ash basin. These eight wells include one background well and seven downgradient wells. The locations of the monitoring wells, the waste boundary, and the compliance boundary are shown on Figure 2. In addition to the eight wells sampled as part of the NPDES permit, the Roxboro Plant samples six monitoring wells and collects landfill leachate samples from four locations associated with the active CCR landfill in accordance with a second permit issued by DENR's Solid Waste Section. The locations of these sample points are shown on Figure 2. Page 7 P: \ Duke Energy Progress.1026 \ALL NC Sn ES\NPDES Permit Deliverables \ Roxboro\GW Monitoring Plan\Roxboro GW Monitoring Plan.doa Groundwater Monitoring Program October 2014 oxboro Steam Plant, NPDES Permit # NC0003425 SynTerra Well construction data for all 14 monitoring wells (active basin and landfill) is provided in Table 1 and Appendix A. Figure 3 is an example of the construction of a typical monitoring well. Based on water levels measured from site wells, the general direction of groundwater flow in the vicinity of the 1966 East Ash Basin and the CCR landfill is to the northwest, toward the plant. The general direction of groundwater flow in the vicinity of the active West Ash Basin is to north, towards the heated water discharge canal system. The site wells provide monitoring data for the groundwater downgradient of the ash basins. The NPDES compliance monitoring network includes one background monitoring well, BGl, and seven downgradient compliance boundary monitoring wells: CW-1, CW-2, CW-213, CW-3, CW-3D, CW-4, and CW-5. Wells CW-313 and CW-4D were installed in the upper bedrock and were paired with shallow wells CW-3 and CW-4, which were installed above the bedrock, to monitor the vertical hydraulic gradient in the area and aquifer conditions within the shallow bedrock. The remainder of the compliance boundary wells were installed in the saprolite or residuum, above bedrock. 4.3 Monitoring Frequency The monitoring wells will be sampled three times per year in April, July, and November. 4.4 Sample Parameters and Methods The monitoring program consists of sampling and analysis for parameters and constituents identified in Permit Condition A (6), Attachment XX of the NPDES permit (Appendix B). The parameters and the analytical methods are presented in Table 2. It is proposed that monitoring for aluminum be discontinued. Aluminum is a very common, naturally -occurring element in soil and rocks of the area. A preliminary statistical evaluation indicates that aluminum concentrations in site groundwater were determined not to be a statistically significant increase over the background well data set. Further, aluminum is not consistently monitored across the entirety of Duke Energy facilities, and there is no 2L Standard for aluminum. The analytical results for the detection monitoring program will be compared to the NC 2L Standards or the site -specific background concentrations.

All measurements will be documented to yield results that are representative of the groundwater quality. Data will be calculated and reported in units as required by the North Carolina Department of Environment and Natural Resources (NCDENR). The analytical QA objectives for precision, accuracy, and completeness have been established by the laboratory(s) in accordance with the Environmental Protection Agency (EPA) or other accepted agencies for each measurement variable where possible. The objectives are outlined in the Duke Energy Analytical Laboratory Procedures Manual and are available upon request. Appropriate methods have been selected to meet applicable standards for groundwater quality. Instances may occur, however, in which the condition of the sample will not allow detection of the desired limits for various parameters either because of matrix interference or high analyte concentrations requiring sample dilution. The laboratory(s) will provide sufficient documentation with each data package to notify reviewers about any analytical problems with the data, if needed. Page 9 P:\Duke Energy Progress.1026\ALL NC SITES\NPDES Permit Deliverables\Roxboro\GW Monitoring Plan\Roxboro GW Monitoring Plw.docc Groundwater Monitoring Program October 2014 oxboro Steam Plant, NPDES Permit # NC0003425 SynTerra 5.0 SAMPLING PROCEDURES 5.1 Sampling Equipment and Cleaning Procedures Development and sampling equipment shall be selected to ensure that materials are compatible with the sample parameters and comply with state and federal regulatory requirements for sampling. New disposable sampling equipment (peristaltic pump tubing) is used for each monitoring well sampled. For non -dedicated equipment used, such as water level tapes and submersible pumps, the equipment will be cleaned before and after use in each well in accordance with standard EPA -approved cleaning procedures for field equipment. This standard is outlined in the Standard Operating Procedures and Quality Assurance Manual, Engineering Support Branch, EPA Region IV, February 1, 1991 as revised December 20, 2011. 5.2 Groundwater Sampling 5.2.1 Development of Monitoring Wells Monitoring wells addressed in this sampling plan have been developed. If new monitoring wells are installed, they will be developed prior to initial sampling. Development removes silt that has settled into the bottom of the well following installation and removes fine silt and clay particles from the well screen and sand -pack surrounding the screen. Well development is necessary to eliminate potential clogging and enhance well performance. Development involves removing an estimated ten or more well volumes from the well using a submersible pump with up-and-down agitation to loosen particles from the well screen. If the turbidity for a well increases over time, the well may be re- developed to restore conditions. 5.2.2 Groundwater Level and Total Depth Measurements Water level measurements are collected and recorded to determine the groundwater elevation and flow direction. Site monitoring wells have been surveyed to determine the elevation of the top of well casing (TOC). Water level measurements are referenced to the TOC and recorded to the nearest one - hundredth of a foot. Water level measurements are made with an electronic measuring device consisting of a spool of dual -conductor wire and sensor. When the sensor comes in contact with water, the circuit is closed and a meter light and/or buzzer Page 10 P:\Duke Energy Progres .1026\ALL NC SITES\NPDES Perudt Deliverables\Roxboro\GW Monitoring Plan\Roxboro GW Monitoring Plan.doo Groundwater Monitoring Program October 2014 oxboro Steam Plant, NPDES Permit R NC0003425 SynTerra attached to the spool signal the contact. When the signal is sounded, the water level is recorded on the Groundwater Monitoring Data Sheet (Figure 4). To minimize sample turbidity, low flow sample methods are used whenever possible. Using low -flow sampling techniques, the volume of the stagnant water in the well is not calculated and the total well depth is not routinely measured to avoid disturbing the bottom sediments. If conditions indicate a possible problem with the integrity of a well, the total well depth may be measured. 5.2.3 Well Purging and Sampling The selection of purging technique is dependent on the hydrogeologic properties of the aquifer and hydraulic characteristics of each well. Hydraulic conductivity, water column, well volume, screen length, and other information are evaluated to select the purging technique to acquire groundwater representative of the aquifer conditions. At the Roxboro Plant, a low -flow purging technique has been selected as the most appropriate technique to minimize sample turbidity. During low -flow purging and sampling, groundwater is pumped into a flow - through chamber at flow rates that minimize or stabilize water level drawdown within the well. At the Roxboro facility, low -flow sampling is conducted using a peristaltic pump or low -flow submersible pump with new tubing. The intake for the tubing is lowered to the mid -point of the screened interval. A multi - parameter water quality monitoring instrument is used to measure field indicator parameters within the flow -through chamber during purging. Measurements include pH, specific conductance, and temperature. Indicator parameters are measured over time (usually at 3-5 minute intervals). When parameters have stabilized within ±0.2 pH units and ±10 percent for temperature and specific conductivity over three consecutive readings, representative groundwater has been achieved for sampling. Turbidity is not a required stabilization parameter, however turbidity levels of 10 NTU or less are targeted. The Groundwater Monitoring Data Sheet (Figure 4) is used to record purge data and field measurements. Instrument calibration is performed and documented before the beginning of the sampling event, at midday, and after each sampling event. The pH subsystem is calibrated with three pH standards (pH 4.0, 7.0, and 10.0) bracketing the expected groundwater pH. The pH calibration is then verified using a different pH 7.0 buffer. The specific conductance subsystem is calibrated using one Page 11 P:\Duke Energy Progress.1026\ ALL NC SPIES\ NPDES Perntit Deliverables\Roxboro\GW Monitoring Plan\Roxboro GW Monitoring Plan.do Groundwater Monitoring Program October 2014 oxboro Steam Plant NPDES Permit A NC0003425 SynTerra standard and verified using a different specific conductance buffer. Calibration results are recorded on a Field Sampling Calibration Form (Figure 5). 5.3 Sample Collection Groundwater samples are collected after the indicator parameters have stabilized. Sampling personnel wear new, clean, disposable, non -powdered nitrile gloves at each location. Samples are collected in the order of the volatilization sensitivity of the parameters: • Metals, metalloids, and selenium • Sulfate, nitrate and chloride • Total dissolved solids Groundwater samples are preserved and stored according to parameter -specific methods and delivered to the laboratory under proper Chant -of -Custody (COC) procedures. All pertinent notations, water -level measurements, removed well volumes, and indicator parameters are documented on the Groundwater Monitoring Data Sheet (Figure 4). 5.4 Sample Containers, Volume, Preservation, and Holding Time Sample containers supplied by the laboratory shall be new and pre -cleaned as approved by EPA procedures appropriate for the parameters of interest. Table 2 summarizes the sample containers, sample volume, preservation procedures, and holding times required for each type of sample and parameter for the monitoring program. Sample containers will be kept closed until used. Sample containers will be provided by Duke Energy or vendor laboratories. 5.5 Sample Tracking The COC procedures allow for tracking the possession and handling of individual samples from the time of field collection through laboratory analysis and report preparation. Samples are logged by the laboratory with a unique tracking number for each sample. An example of the COC Record is provided as Figure 6. 5.6 Sample Labeling Sample containers shall be pre -labeled and organized prior to field activities as part of the pre -sampling staging process. As samples are collected, the sampling personnel write the following information directly on the label: sampling date and time, and initials of sample collector. This information is also recorded on the Groundwater Monitoring Data Sheet (Figure 4) and the COC Record (Figure 6).

Using the internal laboratory QC checks, the laboratories demonstrate the ability to produce acceptable results using the methods specified. Internal quality control checks for sampling procedures and laboratory analyses will be conducted with each sampling event. These checks will consist of the preparation and submittal of field blanks, trip (travel) blanks, and/or field replicates for analysis of all parameters at frequencies described in the laboratory(s) procedures manuals. The field QC blanks and replicates that may be included as internal QC checks are described below. The specific type and number of blanks used may vary depending on the sampling event and will be determined by the Duke Energy field sampling personnel: • Field Blanks: A field blank consists of a sample container filled in the field with organic free, deionized, or distilled water prepared and preserved in the same manner as the samples. The field blank is transported to the laboratory with the samples and analyzed along with the field samples for the constituents of interest to check for contamination imparted to the samples by the sample container, preservative, or other exogenous sources. Field blanks are typically utilized for each sampling event. The field blanks are typically analyzed for major anions, cations and metals. Trip Blanks: A trip (travel) blank is a sample container filled with organic -free water in the laboratory that travels unopened with the sample bottles. Trip blanks are typically utilized when sampling for volatile organic compounds. The trip blank is returned to the laboratory with the field samples and analyzed along with the field samples for parameters of interest. • Equipment Blanks: If non -dedicated equipment is used, it is recommended that equipment blanks be collected. The field equipment is cleaned following documented cleaning protocols. An aliquot of the final control rinse water is passed over the cleaned equipment directly into a sample container and submitted for analyses.

Both the field replicate and the sample are collected at the same time, in the same container type, preserved in the same way, and analyzed by the same laboratory as a measure of sampling and analytical precision.

The general locations forall monitoring wells are indicated on Attachment XX. b. Within 30 days of completion of well construction, a completed Well Construction Record (Form GW-1) must be submitted for each monitoring well to Division of Water Quality, Aquifer Protection Section, 1636 Mail Service Center, Raleigh, NC 27699-1636. C. The Raleigh Regional Office, telephone number (919) 791-4200 shall approve the location of new monitoring wells prior to installation. The regional office shall be notified at least 48 hours prior to the construction of any monitoring well and such notification to the Aquifer Protection Section's regional supervisor shall be made from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays. d. Within 60 days of completion of the monitoring wells, the Permlttee shall submft two original copies of a site map with a scale no greater than 1-inch equals 500 feet. At a minimum, the map shall include the following Information: I. The location and identity of each monitoring well. II. The location of major components of the waste disposal system. lii. The location of property boundaries within 500 feet of the disposal areas. IV. The latitude and longitude of the established horizontal control monument. V. The elevation of the top of the well casing (i.e., measuring point) relative to a common datum. vi. The depth of water below the measuring point at the time the measuring paint is established. vii. The location of compliance and review boundaries. vill. The date the map Is prepared and/or revised. IX. Topographic contours in no more than ten (10) foot intervals e. The above information should be overlaid on the most recent aerial photograph taken of the site. Control monuments shall be installed in such a manner and made of such materials that the monument will not be destroyed due to activities taking place on the property. The map and any supporting documentation shall be sent to the Division of Water Quality, Aquifer Protection Section,1636 Mail Service Center, Raleigh, NC 27699.2636. I. The well(s) must be constructed by a North Carolina Certified Well Contractor, the property owner, or the property lessee according to General Statutes 87- 98.4. If the construction is not performed by a certified well contractor, the property owner or lessee, provided they are a natural person, must physically perform the actual well construction activities. NC0003425 — Roxbom Steam Station Groundwater Monitoring Plan Page 1 of4 31l7/11 g. The monitoring wells shall be regularly maintained. Such maintenance shall Include ensuring that the well caps are rust -free and locked at all times, the outer casing is upright and undamaged, and the well does not serve as a conduit for contamination. MPLIANCE. Monitoring wells shall be sampled after 3, GROUNDWATER SAMPUNG AND CO construction and thereafter at the frequencies and for the parameters as specified In Attachment XX. All maps, well construction forms, well abandonment forms and monitoring data shall refer to the permit number and the well nomenclature as provided on Attachment XX. a. Per 15A NCAC O2H .0000, a Division certified laboratory shall conduct all laboratory analyses for the required effluent, groundwater or surface water parameters. b. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on she top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters. C. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. d. For monitoring wells that are not located at the Compliance Boundary, the Compliance Monitoring Form (GW-59CCR) is not required. However, predictive calculations or modeling shall be submitted to the Regional Office annually (i.e. 12 months after permit Issuance) demonstrating groundwater quality standards at the Compliance Boundary. e. Two copies of the monitoring well sampling shall be submitted on a Compliance Monitoring Form (GW-59CCR), and received no later than the last working day of the month following the sampling month. Copies of the laboratory analyses shall be kept on site, and made available upon request.

(Duke Energy), owns and operates the Roxboro Steam Electric Plant (Roxboro Plant), located near Semora, in Person County, North Carolina. The Plant operates four coal-fired units. Coal combustion residuals (CCR) have historically been managed at the Plant's on -site ash basins: the semi -active East Ash Basin (operated from 1966 to present) and the active West Ash Basin (operated from 1973 to present). An unlined landfill was constructed on top of the East Ash Basin in 1988 for the placement of CCR. A lined landfill was constructed over the unlined landfill in 2004. Figure 1 is a map showing the site and surrounding area. Discharge from the ash basin is permitted by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Resources (DWR) under the National Pollution Discharge Elimination System (NPDES) Permit NC0003425. SynTerra has completed a receptor survey to identify water supply wells, public water supplies, surface water bodies, and wellhead protection areas (if present) within a 0.5 mile radius of the Roxboro Plant ash basins compliance boundary (Figure 1). The compliance boundary for groundwater quality in relation to the ash basin is defined in accordance with 15A NCAC 02L .0107(a) as being established at either 500 feet from the waste boundary or at the property boundary, whichever is closer to the source. The survey scope and findings are presented in the following sections.

The location of the plant is shown on Figure 1. The Roxboro Plant started operations in 1966. The Plant is located on Dunnaway Road, approximately 10 miles north of the city of Roxboro, North Carolina. The Plant is situated on the south side of Hyco Lake, a lake formed from the impoundment of the Hyco River. The Plant property is roughly bounded by Hyco Lake to the north and west, NC Highway 57 (Semora Road) to the south and west, and State Highway 1336 (McGhees Mill Road) to the east. The overall topography of the Plant generally slopes toward the north (Hyco Lake). Wet ash and run off from the East Ash Basin/CCR landfill is contained in the West Ash Basin which encompasses approximately 200 acres. The Roxboro Plant NPDES permit (NC0003425) authorizes two discharges to Hyco Lake. Outfall 003 contains flow from several waste streams and internal outfalls including once -through cooling water, stormwater, and ash basin effluent. Outfall 006 primarily handles runoff from coal pile and other coal handling and discharges to Hyco Lake after neutralization sedimentation, and equalization. 2.2 Description of Surrounding Properties Properties located within a 0.5 mile radius of the Roxboro Plant compliance boundary are located in Person County, North Carolina. The properties uses include primarily residential, agricultural, undeveloped land, and limited commercial/industrial. Figure 1 depicts the properties surrounding the Roxboro Plant.

According to the NC OneMap website, the Public Water Supply Water Sources point data was current through November 18, 2009, and that it is the most current GIS data set of public water supply locations available from North Carolina state agencies. The GIS point data for the public water supply wells includes, but is not limited to information such as public water supply (PWS) system identification numbers, ownership information, PWS source type, well depth, and well yield. The WDMS data set contains information on municipal water lines and other appurtenances. On September 2, 2014, SynTerra reviewed the NCDENR Division of Water Resources (DWR) Source Water Assessment Program (SWAP) online database for public water supply sources to identify wells located within a 0.5 mile radius of the compliance boundary; to confirm the location of wells included in the Public Water Supply Water Sources GIS point data set, and to identify any wellhead protection areas located within a 0.5 mile radius of the compliance boundary. The NCDENR SWAP database provides detailed assessments of all public drinking water intakes and wellhead protection areas in North Carolina. The website address is: (http://swap.ncwater.org/website/swap/viewer.htm). 3.2 Person County GIS Person County on-line GIS information was reviewed to identify any public utilities in the area surrounding the Roxboro Plant and to verify field observations of parcel ownership information. 3.3 Environmental Data Resources, Inc. Records Review A review of public database information provided by Environmental Data Resources, Inc. (EDR) was also conducted. The public water well information has been incorporated in the summary table (Table 1) and on Figure 1. A copy of the EDR report is included as Appendix A.

Hydrography data obtained from the USGS NHD is included on Figure 1. 3.5 SynTerra Field Survey During March 2014, SynTerra personnel conducted a vehicular survey along public roads located within 0.5 mile radius of the compliance boundary. Observations on property use, apparent proximity to available municipal icipal water lines and structures that may represent potential water supply wells were noted. Page 4 P:\Duke Energy Progress.1026 \ ALL NC STIES\NPDES Permit Deliverables\Roxboro\Receptor Survey \ Roxboro Receptor Survey.docx f Receptor Survey October 2014 Roxboro Steam Electric Plant, NPDES Permit A NC0003425 SynTerra 4.0 FINDINGS 4.1 NCDENR Records Two public water supply sources were identified in the Public Water Supply Water Sources GIS point data set (obtained from NC OneMap GeoSpatial Portal) and on the NCDENR SWAP online database within a 0.5 mile radius of the ash basins compliance boundary. One of these sources is a recently installed water supply well located adjacent to Woodland Elementary School (location DW-46 on Figure 1). The other source is the Roxboro Plant's surface water intake, identified on Figure 1 as "EDR Surface Water Intake". No wellhead protection areas were identified on the NCDENR SWAP online database within a 0.5 mile radius of the compliance boundary. The Water Distribution Map Service (WDMS) data set obtained from the NC OneMap GeoSpatial Portal, did not identify municipal water supply lines located within the 0.5 mile radius of the compliance boundary. 4.2 Environmental Data Resources, Inc. Records The EDR report identified one "Water Well" located within 0.5 mile radius of the ash basins compliance boundary. This well is the aforementioned well at Woodland Elementary School and is reported to be 280 feet deep. The EDR report identified the Roxboro Plant surface water intake but incorrectly designated it as a "Public Water Supply Well." A copy of the EDR Report is provided in Appendix A. 4.3 USGS Hydrography Review According to the USGS Hydrography map, Hyco Lake is a major surface water body located within the survey radius (Figure 1). In addition to the reservoir, several surface water features are present within the 0.5 mile radius of the compliance boundary. An intake canal is located east of the Roxboro power plant that brings water from a portion of Hyco Lake northeast of the Plant. A small stream flows north from the small pond located on the east side of the CCR landfill and discharges to the intake canal. Sargents Creek, and several minor tributaries of Sargents Creek, flow from the south into a ponded area at the base of the West Ash Basin filter dam The ponded water flows west and then north through a canal before discharging to the heated wastewater mixing area before ultimately discharging to Hyco Lake (outfall 003). 4.4 SynTerra Field Survey SynTerra conducted a visual reconnaissance of the survey area by driving public road- ways and noting properties that appeared to be developed or occupied. No municipal water lines are present within the 0.5 mile radius of the compliance boundary. Page 5 P: \ Duke Energy Progress. 1026\ALL NC SIIFS\ NPDES Permit Deliverables\ Roxboro \ Receptor Survey \Roxboro Receptor Survey.docx Receptor Survey October 2014 ` Roxboro Steam Electric Plant, NPDES Permit # NC0003425 SynTerra Structures resembling water supply wells or well houses were noted where visible and are shown on Figure 1 as reported/observed water supply wells (DW). Properties within 0.5 mile radius of the compliance boundary that appeared to be developed and in -use (occupied) were assumed to have private water supply wells (PRW) even if not noted during field reconnaissance because no public water supply is available in the area. These properties are indicated on Figure 1. 4.S Summary of Receptor Survey Findings A summary of the receptor survey is discussed below. The suspected water supply well locations shown on Figure 1 are based upon field observations, EDR, and NCDENR information. The suspected well locations are numbered on the map to cross-reference information provided in Table 1. The table summarizes property location and site information where a water supply well may be present based upon drive -by observations or EDR information. No wellhead protection areas were identified within a 0.5 mile radius of the compliance boundary; Approximately 57 possible private water supply wells are assumed to be located within 0.5 mile radius of the compliance boundary; One water well was identified by NCDENR records and the EDR report (Attachment 1). The well is located southwest of the Roxboro Plant at Woodland Elementary School. EDR reports that the well is 280 feet deep, but no other specific information was reported. The well location was observed during field reconnaissance activities; NCDENR records and the EDR report identified the Roxboro Planes surface water intake structure (Figure 1); Several surface water features are present within the 0.5 mile radius of the compliance boundary; and A portion of Hyco Lake is located within the survey radius (Figure 1). i Page 6 P: \ Duke Energy Progress.1026\ ALL NC SPIES\ NPDES Permit Deliverables\ Roxboro\ Receptor Survey\Roxboro Receptor Survey.do« i FIGURE 4 _ LEGEND s� rssurnEG mnArt wAmLswPvwEu (2r1 t1' �'i: Z� PEwPrEnraasEnvEo wArtP wrrtrwuL f.

Assessment of the impact of contaminant migration generally has two principal investigative components: 1. Groundwater flow direction, and 2. Groundwater flow velocity. Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics Of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata. TC3887591.1s Page 1 =GEOCHEM - PHYSICAL SETTING SOURCE SUMMARY GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site -specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers). TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surflcial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

TC3887591.1s Page2 GEOCHECK' -PHYSICAL SETTING SOURCE SUMMARY HYDROLOGIC INFORMATION Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information ran be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgmdient sites might be impacted. AQUIFLOWI Search Radius: 1.000 Mile. EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater flow at specific points. EDR has reviewed reports submitted by environmental professionals to regulatory authorities at select sites and has extracted the date of the report, groundwater flow direction as determined hydrogeologically, and the depth to water table. LOCATION GENERAL DIRECTION MAP ID FROM TP GROUNDWATER FLOW Not Reported TC3887591.1s Pages GEOCHEClt® - PHYSICAL SETTING SOURCE SUMMARY s GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy -gravelly types of soils than silty -clayey types of soils. GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.

Roxboro Steam Electric Plant National Pollutant Discharge Elimination System (NPDES) Permit No. NC0003425 Person County Dear Mr. Belnick: The current NPDES permit for Roxboro Steam Electric Plant located in Person County expires on March 31, 2012. Progress Energy Carolinas, Inc. hereby requests that the North Carolina Division of Water Quality reissue the Roxboro NPDES permit. In accordance with 15A NCAC 21-1.0105, we have enclosed EPA Application Form 1 — General Information, EPA Application Form 2C — Wastewater Discharge Information, and EPA Application Form 2F — Stormwater Discharges Associated with Industrial Activity, all in triplicate. With reissuance of the NDPES permit Progress Energy requests the following: Revise the definition of "Bypass" on Part II Page 1 to reflect the definition as stated in 40 CFR 122.41 as the "intentional' diversion of waste streams. 2. Remove weekly beryllium sampling from outfall 010 based on sampling data from the past three years showing no potential for exceedence of beryllium criteria. Also, please note that when this sampling requirement was initiated with the last permit renewal, the fact sheet referred to the incorrect water quality criterion of 0.0068 ug/l. Recent statutory changes to NCGS 143-215.1 exempt industrial dischargers from having to obtain Authorization to Construct wastewater treatment facilities. With re -issuance of this permit, please remove or revise any permit language requiring the facility to obtain an AtoC to remove the conflict between the General Statute and the permit conditions. 4. Add the following language to the permit to make it consistent with other Progress Energy permits: Progress Energy Carolinas, Inc. Roxboro Steam Plant 1700 Dunnaway Road Semora, NC 27343 The permittee shall not use any biocides except those approved in conjunction with the permit application. The permittee shall notify the Director in writing not later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life other than those previously reported to the Division of Water Quality. Such notification shall include completion of Biocide/Chemical Treatment Worksheet--Form 101. Division of Water Quality approval is not necessary for the introduction of new biocides into outfalls that are tested for whole effluent toxicity. Completion of the Biocide Worksheet is thus, not necessary for those outfalls with toxicity testing requirement. In accordance with EPA form 3510-2C instructions, most effluent sampling data provided on form 2C is from a composite sample. Significant additional sampling results are available from outfall 003 and outfall 006 grab samples. This data is not included with this application but has been provided on the facility's discharge monitoring reports throughout the term of this permit. 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 assure 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. 1 am aware that there are significant penalties for submitting false information, including the possibility offines and imprisonment for knowing violations.

Roxboro Steam Electric Plant National Pollutant Discharge Elimination System Permit Number NC0003425 Attachment 4 Form 2C - Item II-B Flows, Sources of Pollution, and Treatment Technologies Attachment 4 Form 2C - Item II-13 Flows, Sources of Pollution, and Treatment Technologies Introduction The Roxboro Steam Electric Plant, located in Person County, North Carolina, consists of four coal fired generating units with nameplate generating capacities of 410.8, 657, 745.2, and 745.2 MWe for units 1, 2, 3, and 4 respectively. All plant waste streams are routed directly or indirectly to the Hyco Reservoir. Chemical constituents contained in these discharges will, in part, be representative of the naturally occurring chemical quality and quantity of the intake water and will also have chemical constituents of such quality associated with similar discharges for fossil generating facilities of this size, type, and in this geographical location. Either all or part of the elements in the Periodic Table, either singularly or in any combination, may from time to time be contained in the discharges. Each component of the discharges is described below. Outfall 003 — Effluent Channel At the point that the effluent channel enters the Hyco Reservoir, it contains the flows from several waste streams, including once -through cooling water, stormwater runoff, and the effluent from the ash pond, which in turn receives and treats combined flows from the ash transport system, the low volume waste system, the dry fly ash handling system, cooling tower blow down, stormwater runoff, drainage from the ash landfill, east ash pond and from occasional wastewater piping leakage. Once -Through Cooling Water Condenser Cooling Water (CCW) for Units 1, 2, and 3 is drawn from the Hyco Reservoir via an intake canal and discharges to the Hyco Reservoir via a effluent channel. Flows for Units 1, 2, and 3 are 249 MGD, 342 MGD, and 505 MGD respectively. Cooling is accomplished by evaporation from the surface of cooling water in the effluent channel, cooling towers, mixing and convection with Hyco reservoir waters. During the summer months, Unit 3 CCW is routed through mechanical draft cooling towers where most of the waste heat is removed by evaporation before the water is discharged to the reservoir via the effluent channel along with the CCW of Units 1 and 2. Additionally, once -through cooling water is used for heat exchange of component closed cooling water, the flow of which is combined with the CCW prior to introduction into the effluent channel. Stormwater Runoff The stormwater, which flows into the discharge canal includes runoff from the plant drainage area, the drainage area from the dry fly ash handling system (including roadways), Unit 4 cooling tower drainage area, the fuel oil storage containment area, the switchyard drainage area, the anhydrous ammonia tank farm, and the gypsum storage pile area. Ash Pond Discharge The ash pond receives ash transport water, low volume wastes, runoff from the ash landfill, landfill leachate, dry fly ash handling system wash water, blow down from Unit 4 cooling tower, coal mill rejects and pyrites, and sewage treatment plant effluent. The pond provides treatment by sedimentation, oxidation, neutralization, equalization, adsorption and chemical precipitation. Ash Transport Water Water for sluicing ash to the ash pond is withdrawn from the CCW system as needed. The plant will primarily supply ash sluice water from Unit 2. However, the facility will continue to maintain the ability to operate the unit 4 ash sluice pumps. The Unit 4 ash sluice pumps are and will continue to be utilized for the following i) during maintenance draining of the cooling tower, ii) back-up supply for the fire suppressant system, and iii) ash sluicing pumps during operational events which require additional 2 pumping. Normally, only bottom ash is conveyed to the ash pond by sluicing. Fly ash is handled dry by a pneumatic system and is land filled on site or sold. If the dry fly ash handling system is out of service during plant operating periods, fly ash will be sent to the ash pond via the ash sluicing systems until the dry system is restored. Such occurrences are expected to be infrequent and brief. Silo Wash Water Ash silo wash water runoff and dust suppressant spray runoff from the dry fly ash handling system are routed to the ash pond. Low Volume Wastes Boiler make-up water is withdrawn from the intake and filtered, softened, and de-mineralizered for treatment. This process includes treatment via a process water reverse osmosis system. Boiler water is treated with ammonia, hydrazine, phosphate and occasionally sodium hydroxide. Boiler blow down is sent to the ash pond via the low volume wastes collection system (LVWS). These are special drains in the plant that flow by gravity to collection sumps and are pumped to the ash pond. Ethylene glycol is used for freeze protection of some equipment and may be discharged to the LVWS, as is some molybdate waste from the closed cooling water system, during periods of maintenance. When this equipment is rinsed, small amounts of these chemicals are discharged to the low volume system via the neutralization basin. The plant's Reverse Osmosis system produces a continuous reject wastestream of approximately 250 gpm. Essentially all plant equipment, floor drains, water treatment filter backwashes, clarifier and sedimentation basin sludge, and ash hopper seal water overflow also discharge to the LVWS. Plant drains around oil containing equipment are routed to an oil/water separator for treatment prior to being sent to the ash pond via the LVWS. Various boiler sediments and ash accumulations collected during 3 maintenance activities may also be transported to the ash pond or the onsite ash landfill. Seepage through the ash pond dam may be released to the effluent channel. Cooling Tower Blow down Unit 4 is the only unit that produces cooling tower blow down. A blow down stream is used to maintain concentrations of total dissolved solids in the cooling tower to within proper operating limits. Make-up to the Unit 4 cooling tower is from the Heated Water Discharge Canal. Domestic Sewage Domestic sewage is treated by an extended aeration treatment plant consisting of a screen, comminutor, surge tank, aeration tank, clarifier, chlorine contact chamber, and a sludge holding tank. Air Preheater Cleaning (Low Volume Waste) The air preheater will be water washed once per year or more frequently as needed. The wastewater from this activity will be discharged to the ash pond. Chemical Metal Cleaninq Wastes The boilers are chemically cleaned approximately every five -to -eight years as required using Tetraammonia ethylene diamine tetraaccetic acid (EDTA) solution or citric acid. This cleaning solution and its rinses are stored on site for disposal by evaporation in an operating unit's furnace. Should evaporation not be used, the wastewater can be treated by neutralization and precipitation prior to being conveyed to the ash pond. Alternatively, the wastewater can be disposed by other acceptable disposal methods. Cleaning of other heat exchanger surfaces may C! produce 5,000-10,000 gallons of wastewater approximately every three - to -five years. Flue Gas Desulfurization Blow down (Low Volume Waste) The Flue Gas Desulfurization (FGD) system directs flue gas into an absorber where limestone (calcium carbonate) slurry is sprayed. Sulfur dioxide in the flue gas reacts with the limestone slurry to produce calcium sulfate (gypsum). The system reclaims any un-reacted limestone slurry to be reused in the absorber. A small blow down stream is used to maintain the chloride concentration in the reaction tank. The blow down stream is discharged to a gypsum settling pond where suspended solids are settled out prior to entering a bioreactor. The bioreactor utilizes microbes to reduce soluble contaminants to insoluble forms that then precipitate from solution. The treated wastewater enters the ash pond effluent channel prior to outfall 002. Flue Gas Desulfurization (FGD) System Blow down Emergency Overflow/Pipeline Drain Emergency overflow from the FGD System blow down will discharge to the ash pond. If the FGD System blow down pipeline requires emergency draining, the contents of the pipeline will be drained to a sump that is pumped to the ash pond. Ash Landfill Drainage Water for sluicing a minimum amount of bottom ash to the ash landfill is withdrawn from the ash transport system as needed. The bottom ash is used to enhance the subsurface drainage of the landfill. 5 The facility may transfer settled ash from the west ash pond to fill remaining capacity in the east ash pond as needed. This activity may be undertaken to provide treatment capacity (i.e. volume) in the active, west ash pond and or in preparation for landfill expansion in accordance with permits issued through the NC Division of Solid Waste. Stormwater Runoff The stormwater runoff, which flows into the ash pond includes runoff from the plant drainage area, landfill runoff (including silo area drainage), and the drainage area from the ash pond (including roadways). Outfall 006 — Coal Pile Runoff Runoff from the coal pile, limestone pile, small potential gypsum pile on the west side of the plant, truck wheel wash and other coal handling areas of the plant is routed to a retention pond for treatment by neutralization, sedimentation, and equalization. The pond is designed to store in excess of the 10-year/24-hour storm event. Releases are controlled by a standpipe and skimmer discharge structure. Approximately 0.006 MGD of wheel wash water will be sent via gravity drain to a solids settling basin. Solids from the wheel wash will accumulate in a separate settling basin to be removed by front end loaders and sent to the onsite landfill. Only the water will be going to the coal pile runoff pond via the gravity drains. 0 Carolina Power & Light Company d/b/a Progress Energy Carolinas, Inc.

With regard to your letter describing changes in Section 3.2.2 Observation and Sampling • The discussion must include a statement noting that jurisdictional determinations regarding the extent of waters of the United States and their relationship with identified seeps at the subject facilities will be obtained from the United States Army Corps of Engineers (USA COE). Duke Energy does not yet have jurisdictional determinations from the US Army Corps of Engineers for the relevant areas at all of the twelve sites mentioned in your letter. We submitted applications for jurisdictional determinations in September, October, and November 2015 and have since worked with the Corps of Engineers to schedule site visits and provide draft plats for approval. Nonetheless, the timing of the approved jurisdictional determinations is up to the Corps and outside of Duke's control. To date, out of these twelve sites, only Buck has an approved jurisdictional determination, but we do not yet have the signed plats. We will submit the maps you have requested for each site on a rolling basis, within a reasonable period after the jurisdictional determinations are complete. In order to address the changes described in your March 2, 2016 letter, we have added the following text at the start of Section 3.2.2. Jurisdictional determinations regarding the extent of waters of the United States and their relationship with identified seeps at the subject facilities will be obtained from the United States Army Corps of Engineers (USA COE). Until jurisdictional determinations are finalized by USA COE, preliminary information will be used to evaluate the seeps as described in the section below. RECEIVED/NCDEA/DWR MAY 0 b m16 Water Quality Permitting Section The second change in Section 3.2.2 described in your letter is as follows. The schedule for water quality sampling of the seeps and related jurisdictional waters must be more frequent than the semi-annual basis stated in the proposed OAPs. DWR recommends a monthly monitoring schedule, consistent with the conditions described in the DAPs' general assessment requirements, for all identified seeps that will continue for twelve ( 12) months. After that time, monitoring may be reduced to a semi-annual basis until such monitoring becomes a requirement of the NPDES permit. We do not believe sampling monthly as part of a revised Discharge Assessment Plan is warranted. For the larger receiving waters, data is available from sampling associated with NPDES permits that demonstrates the lack of impact on the larger surface waters of the state. In addition, we are conducting weekly observations of all AOWs on a dam or dike slope, sampling any new seeps, and providing the analytical results to DEQ. We recommend the sampling frequency under the DAPs remain at twice/year with the weekly inspections of dam slopes for any new seeps with data provided to DEQ. We recommend that we collectively focus our resources on the completion of all of the NPDES Wastewater Permits for the Duke Energy sites and implement appropriate sampling frequency for each of the permitted seeps in that document . However, in order to address the changes described in your March 2, 2016 letter, we have added the following text in Section 3.2.2. In addition to sampling conducted with the semi-annual assessments, additional seep sampling will be conducted at locations and at a frequency as determined through discussions with NC DEQ personnel. We would like to work with DEQ to achieve alignment of the various (present and future) documents involving required seep activities including: • Discharge Assessment Plans • Discharge Identification Plans • NPDES Wastewater Permits • EPA requirements • Any future legal agreements with either DEQ or EPA Duke Energy is committed to providing the Department with additional information to facilitate the issuance of new NPDES Wastewater permits. The issues are complex and require special consideration, as illustrated by the time elapsed since the permit applications were submitted. We look forward to working with you further to resolve the issues identified here on a mutually acceptable schedule.

Duke Energy Progress, LLC I Discharge Assessment Plan F�� Roxboro Steam Electnc Plant Ash Basin J SECTION 2 - SITE BACKGROUND Section 2 - Site Background 2.1 Plant Description The Roxboro Steam Electric Plant (Roxboro Plant) is located in north -central North Carolina near Semora, North Carolina. A large part of the Roxboro Plant property encompasses Hyco Lake (Figure 1). The Roxboro Plant is located in Person County along the east bank of Hyco Lake north of Roxboro, North Carolina, and west of Mcghees Mill Road. The Roxboro Plant began operations in 1966. Additional units were added in 1968, 1973, and 1980. Throughout its operational history, the Roxboro Plant has used coal-fired units to produce steam. Ash generated from coal combustion is stored on site in ash basins. 2.2 Ash Basin Description Ash generated from coal combustion has been stored in on -site ash basins and lined landfill. Ash has been sluiced to the ash basins or conveyed in its dry form to the lined landfill. Two ash basins areas have been used at the Roxboro Plant and are referenced using the date of construction and relative location: the 1966 semi -active East Ash Basin and the 1973 active West Ash Basin. The East Ash Basin is located southeast of the Roxboro Plant, and the West Ash Basin is located south of Roxboro Plant. An unlined landfill was constructed on the East Ash Basin in the late 1980s. A lined landfill was subsequently constructed over the unlined landfill around 2004. The ash basins are impounded by earthen dams. Currently, the East Ash Basin and lined landfill are covered with vegetation where the landfill is not active (grasses and shrubs). The West Ash Basin has some grass cover and ponded water, mostly along the southern and eastern edges of the basin. Wet ash and run off from the East Ash Basin landfill is directed to the West Ash Basin for settling. The West Ash Basin encompasses approximately 200 acres and discharges by a permitted outfall into Hyco Lake. 2.3 Site Geologic/Soil Framework The Roxboro Plant is situated geographically in the eastern Piedmont Region of north -central North Carolina and is near the contact of two regional geologic zones. The geologic zones include the Inner Piedmont zone, characterized by biotite gneiss and schist, and the Charlotte Belt, distinguished by felsic mica gneiss. Both zones are generally comprised of igneous, metamorphosed igneous, and sedimentary rocks of Paleozoic age. The bedrock is largely fractured, folded, and has been subjected to long periods of physical and chemical weathering. The weathering has produced 10 feet to 30 feet of unconsolidated residuum and saprolitic soil overlying bedrock at the site. One of the most important interpretations concerning the geologic nature of the region is the discovery and description of the Hyco shear zone, a tectonic boundary comprised of a ductile shear zone that sharply separates contrasting rocks of the Charlotte (Milton) and Carolina Terranes in north -central North Carolina and southern Virginia (Hibbard, et. al., 1998). The Hyco shear zone was mapped as directly underlying Hyco Lake. Duke Energy Progress, LLC I Discharge Assessment Plan �J1� Roxboro Steam Electric Plant Ash Basin SECTION 2 - SITE BACKGROUND Shallow groundwater generally flows from local recharge zones in topographically high areas, such as ridges, toward groundwater discharge zones, such as stream valleys. Ridge and topographic high areas serve as groundwater recharge zones, and groundwater flow patterns in recharge areas tend to develop a somewhat radial pattern from the center of the recharge area outward toward the discharge areas and are expected to mimic surface topography. 2.4 Topographic Map and Identification of Discharges A topographic map is presented in Figure 2 to meet the requirements of GS 130A-309.210(a) in the identification of outfalls from engineered channels, as well as seeps and weeps. Seepage is the movement of wastewater from the ash basin through the ash basin embankment, the embankment foundation, the embankment abutments, basin rim, through residual material in areas adjacent to the ash basin. A seep is defined in this document as an expression of seepage at the ground surface. A weep is understood to have the same meaning as a seep. Indicators of seepage include areas where water is observed on the ground surface and/or where vegetation suggests the presence of seepage. Seepage can emerge anywhere on the downstream face, beyond the toe, or on the downstream abutments at elevations below normal pool. Seepage may vary in appearance from a "soft," wet area to a flowing "spring." Seepage may show up first as only an area where the vegetation is lusher and darker green than surrounding vegetation. Cattails, reeds, mosses, and other marsh vegetation often become established in a seepage area. However, in many instances, indicators of seeps do not necessarily indicate the presence of seeps. Areas of apparent iron staining and/or excess iron bacteria may also indicate the presence of a seep. Locations of seepage at the ground surface adjacent to the ash basin have been identified and are shown in Figure 2. These areas include the earthen embankments which impound the ash basin as well as adjacent areas where water from the ash basin may have infiltrated into the underlying residual materials and expressed as seepage. 2.4.1 Engineered Drainage System for Earthen Dam Earth dams are subject to seepage through the embankment, foundation, and abutments. Seepage control is necessary to prevent excessive uplift pressures, instability of the downstream slope, piping through the embankment and/or foundation, and erosion of material by migration into open joints in the foundation and abutments. The control of seepage is performed by the use of engineered drains such as blanket drains, trench drains, and/or toe drains. In certain cases horizontal pipes may be installed into the embankment to collect and control seepage. It is standard engineering practice to collect the seepage and convey seepage away from the dam. The Roxboro Plant West Ash Basin was constructed with an internal chimney drain to collect seepage water through the dam. The chimney drain transmits water through a series of chimney drain outlets (7) toward the permitted outfall at Hyco Lake. The drainage features, or outfalls, associated with the ash basin dam are shown as required by GS 130A-309.210(a)(2)(i) on Figure 2. Duke Energy Progress, LLC I Discharge Assessment Plan 1 1� Roxbom Steam Electric Plant Ash Basin J SECTION 2 • SITE BACKGROUND 2.4.2 Non -Engineered Seep Identification Topographic maps of the site were reviewed to identify regions of the site where there was a potential for ash basin related seepage to be present. These regions were determined by comparing ash basin full pond elevations to adjacent topography with ground surface elevations lower than the ash basin full pond elevation. Synterra staff performed site observations within these identified areas as part of NPDES inspections during the reapplication process during August 2014 and documented locations where seepage was apparent at the time of the site visit. These seeps are identified as required by GS 130A-309.210(a)(2)(ii) on Figure 2. Duke Energy Progress, LLC I Discharge Assessment Plan Rozbom Steam Electric Plant Ash Basin 11-N SECTION 3 • DISCHARGE ASSESSMENT PLAN Section 3 - Discharge Assessment Plan 3.1 Purpose of Assessment The purpose of the assessment is to determine whether existing, known discharges from toe drain outfalls, seeps, and weeps associated with the coal combustion residuals surface impoundment (ash basin) have reached the surface waters of the State and have caused a violation of surface water quality standards as required by North Carolina General Statute 130A- 309.210(b). Figure 2 and Table 1 present the background and downstream sampling locations to be considered as part of this Discharge Assessment Plan (DAP). These locations may be assessed by comparing surface water sampling analytical results of the associated background location with the corresponding downstream location. For discharges located at the toe of a dam, an upstream location within the channel may not have been possible to isolate for comparison given the proximity to the ash basin, which would have the same chemical composition as the discharge itself. As such, the upstream location was established upstream of the ash basin and is considered "background." For discharges located a distance from the ash basin, an identified upstream, or "background" location for sampling may be compared to the downstream portion of the discharge channel. The background and downstream sampling locations are shown on Figure 2 with "B" and "D" identifiers, respectively, and the corresponding seep locations associated with the sampling locations are indicated on Table 1. 3.2 Assessment Procedure The assessment procedure associated with the Roxboro Plant ash basins is provided within this section. In addition to the specific requirements for the assessment, Section 3.2 also provides the general requirements, the frequency of assessment, documentation requirements, and a description of the surface water quality analyses that will be performed. 3.2.1 General Assessment Requirements Assessments are to be performed in three phases as follows: • Observation and sampling (assessment site visit), • Evaluation, and • Assessment reporting. The assessment site visit shall be performed when the background and downstream locations are accessible and not influenced by weather events. Locations on or adjacent to the ash basin embankments should be performed within two months after mowing, if possible. In addition, the assessment site visit should not be performed if the following precipitation amounts have occurred in the respective time period preceding the planned assessment site visit: Precipitation of 0.1 inches or greater within 72 hours or Precipitation of 0.5 inches or greater within 96 hours. The assessments shall be performed under the direction of a qualified Professional Engineer or Professional Geologist on a semi-annual basis within two nonadjacent quarters. The date of the Duke Energy Progress, LLC I Discharge Assessment Plan Roxbom Steam Electric Plant Ash Basin SECTION 3 - DISCHARGE ASSESSMENT PLAN initial assessment site visit shall be selected no later than 30 days from the approval of the Discharge Assessment Plan and should fall within one of the semi-annual timeframes. Additional seep locations that may have been identified and documented in an Identification of New Discharge report(s) shall be reviewed prior to performing an assessment site visit, if available. 3.2.2 Observation and Sampling Jurisdictional determinations regarding the extent of waters of the United States and their relationship with identified seeps at the subject facilities will be obtained from the United States Army Corps of Engineers (USACE). Until jurisdictional determinations are finalized by USACE, preliminary information will be used to evaluate the seeps as described in the section below. The initial assessment site visit should be performed to document baseline conditions of the discharge channel, including location, extent (i.e., dimensions of affected area), and flow of each discharge. Discharge channel background and downstream locations should be verified using a Global Positioning System (GPS) device. Photographs should be taken from vantage points that can be replicated during subsequent semi-annual assessments. Initial and subsequent assessment site visits shall document a minimum of the following to respond to the requirements in 130A-309.21 0.1 (b): Record the most recent ash basin water surface elevation and compare to the seep and outfall and associated discharge location surface water elevations. For each discharge channel, the observer shall note the following as applicable on the day of the assessment site visit: o Is the discharge channel flowing at the time of the assessment site visit? o Does the discharge channel visibly flow into a Water of the U.S. at the time of the assessment site visit? o How far away is the nearest Water of the U.S.? o Document evidence that flow has or could reach a Water of the U.S. (e.g., description of flow, including extent and/or direction) and describe the observed condition. Evidence that flow could or has reached a Water of the U.S. may be indicated by an inspection of the adjacent and downstream topographic drainage features. o Observe and document the condition of the discharge channel and outfall of the engineered channel or seep location with photographs. Photographs are to be taken from similar direction and scale as photographs taken during the initial assessment site visit. Record flow rate within the discharge channel, if measureable, using the following methods: Duke Energy Progress, LLC I Discharge Assessment Plan �1J� Roxboro Steam Electric Plant Ash Basin SECTION 3 - DISCHARGE ASSESSMENT PLAN o Timed -volumetric method: Collect a volume of water from the discharge of the PVC pipe directly into an appropriately sized container. Measure volumes (in mL) in the field utilizing a graduated container. Record the amount of time (in seconds) needed to collect the volume of water and calculate the flows (in MGD) for the timed -volume. A V-notch weir apparatus will be installed, if necessary, during the initial assessment site visit to impound seepage at locations with a defined channel. Once the impounded seep reaches equilibrium discharge, flows will be measured using the timed -volumetric method described above. Area -velocity method: Measure point velocities and water depth at a minimum of 20 stations along a transect setup perpendicular to the direction of flow using a Swoffer® 3000 flow meter mounted to a standard United States Geologic Survey (USGS) top -set wading rod. Utilize the average velocity and cross -sectional area of the wetted channel to calculate flows in MGD. • Collect water quality samples using the following methods: Collect background and downstream samples during a period with minimal preceding rainfall to minimize potential effects of stormwater runoff. Sampling procedures should prevent the entrainment of soils and sediment in water samples that can result in analytical results not being representative of the flow. Because Areas of Wetness (AOWs)/seeps often have poorly defined flow channels and minimal channel depth, conventional grab samples collected directly into laboratory containers or intermediate vessels is not possible without disturbance and entrainment of soils and sediments. Further, many AOWs are contiguous with low- lying areas subject to surface water runoff and resulting heavy sediment loading during storm events or are near surface waters subject to flooding such that representative samples of the AOW cannot be obtained. If the facility is unable to obtain an AOW sample due to the dry, low flow or high flow conditions preventing the facility from obtaining a representative sample, a "no flow" result or "excessive flow" will be recorded. After collection, samples will be preserved and stored according to parameter - specific methods and delivered to the laboratory under proper Chain -of -Custody (COC) procedures. Analytical parameters for analysis include: Fluoride, Arsenic, Cadmium, Copper, Chromium, Nickel, Lead, Selenium, and Mercury. This list includes all parameters previously identified for seep sampling at Duke Energy power plants for which relevant stream water quality standards are in place. (This list is responsive to the statutory requirement for the discharge assessment to allow determination whether discharges from toe drain outfalls, seeps, or weeps have reached surface waters and caused a violation of surface water quality standards.) Analyses shall be conducted by Duke Energy's Huntersville Analytical Laboratory (NC Wastewater Certification #248) and Pace Analytical Laboratories (NC Wastewater Certification Duke Energy Progress, LLC I Discharge Assessment Plan ��� Roxboro Steam Electric Plant Ash Basin SECTION 3. DISCHARGE ASSESSMENT PLAN # 12). Laboratory analytical methods used for each constituent are provided in Table 2. Seep in -situ measurements: In -situ field parameters (temperature and pH) shall be measured utilizing calibrated field meters either at the discharge of the seep directly, at the discharge of the flow measurement devices, or in the water pool created behind the device, if sufficient water depth did not exist at the device discharge. Hyco Lake and Ash Basin Sample Collection Method: Water quality samples and in -situ measurements from Hyco Lake shall be collected at a location upstream and downstream of the ash basin. Additionally, water samples and in -situ measurements shall be collected from an in -process ash basin location. The grab samples shall be collected from the river and basin's surface (0.3 m) directly into appropriate sample bottles. In addition to sampling conducted with the semi-annual assessments, additional seep sampling will be conducted at locations and at a frequency as determined through discussions with NC DEQ personnel. 3.2.3 Evaluation Evaluation of the data from the initial assessment site visit will establish baseline conditions and will serve as the basis for comparison for subsequent assessment site visit results. Evaluation of observations and sampling results shall include location, extent (i.e., dimensions of affected area), and flow of each discharge. The analytical results of the upstream and downstream locations shall be compared to the 15A NCAC 2B standards for surface water quality upon receipt to identify potential exceedances. 3.2.4 Assessment Reporting Each assessment site visit shall be documented by the individual performing the assessment, as described in Section 3.2.2 to meet the requirements in 130A-309.21 0.1 (b). The report should contain site background, observation and sampling methodology, and a summary of the observations and descriptions of the discharge channels observed, changes in observations compared to previous assessment events, estimates of flows quantities, and photographs of discharges and outfalls of engineered channels designed or improved for collecting water from the impoundment. Photographs are to be numbered and captioned. The flow and analytical results shall be recorded and presented in tables similar to the examples provided as Tables 1 and 3. The analytical results shall be compared to the 15A NCAC 2B standards for surface water quality and exceedances highlighted. This information shall be compiled, reviewed, and submitted to NC DEQ within 90 days from the Observation and Sampling event.
