Cape Fear Steam Electric Plant NPDES Permit NC0003433 NPDES Application Update Dear Messrs. Poupart and Bennett: Cape Fear Steam Electric Plant 500 C P & L Road Moncure, NC 27559 Duke Energy Progress, Inc. (Duke Energy) hereby provides this update to the NPDES permit application package submitted on December 2, 2010. This amendment reflects current wastewater and stormwater sources and flows at the Cape Fear Steam Electric Plant, Chatham County. Enclosed are copies of the affected pages of EPA Forms 1, and 2C, with attachments, that have changed since our current NPDES wastewater permit became effective in January 2012. Specifically, the following modified pages are included. • EPA Form 1; • EPA Form 2C, pages 1-4; • An updated flow chart and description of wastewater flows (Form 2C Attachment 2- Item II -A, page A2-1 through A2-2); • An updated narrative description of sources of pollution and treatment technologies (Form 2C Attachment 3 Item II -B, pages A3-1 through A3-5); and • An updated list of potential discharges not covered by analysis (Form 2C Attachment 4 Item VI pages A4-1 through A4-2). The following supplemental information has also been enclosed: • Seep Monitoring Report for Cape Fear Steam Electric Plant - June/July 2014 • Groundwater Monitoring Program, Sampling, Analysis, and Reporting Plan for Cape Fear Steam Electric Plant • Receptor Survey for Cape Fear Steam Electric Plant Duke Energy has also enclosed an updated Form 2F for stormwater outfalls associated with industrial activities at the Cape Fear Plant that was included with the 2011 NPDES permit renewal application package. Stormwater outfalls were historically permitted through the plant's NPDES permit. As you recall, the North Carolina Department of Environment and Natural Resources (NCDENR) indicated their intent to separate industrial stormwater from the wastewater permit during the 2011 renewal timeframe. Before the new individual stormwater permit was issued, Duke Energy submitted a request to withdraw the stormwater application based on the changed conditions at the plant due to ongoing demolition projects where the stormwater watersheds no longer drain areas with industrial activity. A request to withdraw the subject permit application was made in a letter from Mr. Danny Wimberly to Ms. Bethany Georgoulias dated December 13, 2012 (Form 2F Attachment 2). NCDENR concurred that an NPDES Stormwater discharge permit was not applicable (Form 2F Attachment 3). Since January 2013, demolition activities have continued at the site. Duke Energy believes that the same factors are in place which led NCDENR to determine that an NPDES stormwater discharge permit is not applicable at this time. Those key factors are: 1. The plant is no longer generating power. Some non -categorical stormwater (drainage from plant areas) is still being routed to the ash ponds while the plant is being demolished. This volume of stormwater is diminishing as pump stations are cleaned and removed during the demolition process. 2. The 2011 draft stormwater permit proposed four stormwater (SW) outfalls (Outfalls SW001, SW002, SW003, and SW008). These outfalls are not currently impacted by industrial activity. a. Outfalls SWO01 and SW008 drain areas from the inactive ash basins. These basins have not been used in 30+ years, are fully vegetated/forested, and there are no exposed materials. In the past, NCDENR determined that these outfalls do not require permit coverage since discharges are not possible in events smaller than the 25 -year, 24-hour storm. b. Outfall SWO02 was originally proposed to capture runoff from the railroad. Coal is no longer being brought onsite by rail (or any other means). c. Outfall SWO03 was originally proposed to contain potential leakage and minimize environmental impact from an ash sluice line. Ash is no longer being sluiced and the line has been physically disconnected. 3. There is no storage of raw industrial materials onsite. 4. Stored coal has been removed from the plant site and the remaining area has been covered with soil and grass in accordance with the approved Erosion and Sedimentation Control (E&SC) plan. 5. The #2 Fuel oil storage tanks have been removed from the site. 6. The site has an approved E&SC plan and is subject to the Stormwater General Permit for Construction -Related Activities (NCG010000), also called Construction Stormwater. 7. Should conditions at the site change in a manner that would subject stormwater to industrial activity, Duke Energy will work with NCDENR to secure the necessary permits. Based on the above-mentioned factors, Duke Energy believes that the Construction Stormwater Permit is the appropriate permitting mechanism for this site. However, we are hereby providing an updated Form 2F with 2010 data (our applicable 'current' application), plus additional stone event data from historic outfalls SW -002 and SW -003 (Form 2F Attachment 4) to provide NCDENR with a full characterization of stormwater activities at this site. Duke Energy asks that DENR use this information to confirm it's previous determination that an individual stormwater permit is not currently applicable at this site.

NPDES Permit NC0003433 Cape Fear Steam Electric PIant 2014 Permit Application Amendment Attachment 3 Form 2C - Item II -B Description of Operations Contributing Wastewater The Cape Fear Steam Electric Plant is a retired steam cycle electric generating plant that formerly consisted of two coal-fired units, two heat recovery boilers and four Internal Combustion (IC) Turbines. The site was retired in 2011 and is currently being demolished. No industrial activity is currently occurring onsite. All wastewaters formerly generated by the site historically discharged to the effluent channel prior to the combined outfall (Outfall 007). Components of the discharges and wastestreams are described below. Additionally, a detailed map with the location of various seeps on the property is being provided as part of this permit application. Four stormwater outfalls were historically permitted through the NPDES permit. A discussion of those outfalls is included in this document following the wastewater discussion. Chemical constituents contained in the discharges from this site will, in part, be representative of the naturally -occurring chemical quality of the intake water and will also have chemical constituents of such quality and quantity associated with similar discharges for fossil generating facilities of this size, type, and in the geographical location. Either all or part of the elements listed on the Periodic Table, either singularly or in any combination, may from time to time be contained in the discharge until the ash basins are permanently closed. Outfall 007 Combined Wastewater Discharge This outfall contains all waste stream flows including West Ash Pond discharge, once -through cooling water, and East Ash Pond discharge. Outfall 007 is located in the effluent channel approximately 250 feet downstream of the last internal outfall. Downstream of the effluent channel, the manmade canal becomes an unnamed tributary which flows to the Cape Fear River. West Ash Pond 0978 Pond) Discharge — Internal Outfall 001 The West Ash Pond formerly received coal pile runoff, settling basin drains, No. 2 fuel oil tank runoff, sand bed filter backwash, parking lot drains, equipment cooling tower blowdown and drain, boiler blowdown, oil unloading area drains, demineralizer regenerate, various yard and floor drains, ash trench drain, and miscellaneous low volume wastes. This pond also received bottom and fly ash either by ash transport system waters or by truck. The ash pond provides treatment by sedimentation, oxidation, neutralization, equalization, and adsorption. The dry areas of the ash pond may be treated with dust suppressant. Although all waste stream contributions to the ash pond will be eliminated, waste water remaining in the basin will continue to be removed through existing outfalls. As the water in the ash pond lowers, additional treatment may be brought onsite to ensure the ash pond discharge maintains compliance with NPDES permitted limits, such as a portable filtration unit. Descriptions of the individual waste streams are below. Coal Pile Runoff The coal has been removed and the "coal pile area" has been covered with soil and graded in accordance with an approved Erosion and Sedimentation Control Plan. Historically, storm water runoff from the coal pile was routed to the West Ash Pond for treatment. Low Volume Wastes The low volume wastes retention basin contains an oil water separator and historically received various plant process wastes streams and stormwater from industrial areas. In 2013 Duke Energy submitted to NCDENR a 90- day closure letter for this basin. This basin will be cleaned and breached A3-1 Duke Energy Progress, Inc. NPDES Permit NCO003433 Cape Fear Steam Electric Plant 2014 Permit Application Amendment in accordance with that closure letter. Comingled wastewater from this basin flowed to the West Ash Pond. Boiler blowdown, drainage, and wastes from the equipment cooling tower and its associated heat exchangers may have contained minute quantities of treatment chemicals. The small quantities of these low volume wastes were sent to the low volume wastes retention basin. Miscellaneous Wastes Plant area floor and yard drains were routed to the West Ash Pond and included equipment drainage wash down water, and rainfall runoff. Drains from areas likely to contain oil -filled equipment or storage were routed to the low volume wastes retention basin which contained an oil/water separator. Waste oil was disposed of according to the appropriate regulations. Internal combustion turbine facility false start drain tanks were discharged into the low volume wastes retention basin. Cooling tower basin sludge, residuals from the low volume wastes retention basin and the coal pile ditch; ash trench materials; circulating water tunnel sediment; boiler, electrostatic precipitator, and associated appurtenances vacuuming sediments; sludge from catch basins, sumps, etc.; and other miscellaneous low volume wastes from plant process were also transported to the West Ash Pond. Once -through Cooling Water— Internal Outfall 003 Once -through condenser cooling water for the coal fired units and heat recovery units was withdrawn from the Cape Fear River, passed through the condenser, and discharged directly into the effluent channel. Some cooling was accomplished in the effluent channel. When the temperature at Outfall 007 approached 32°C, cooling towers were placed in service to keep the channel water at or below 32°C. East Ash Pond (1985 Pond) — Internal Outfall 005 The East Ash Pond historically received ash transport waters (bottom and fly ash), runoff from yard drains, air preheater washes, electrostatic precipitator washes, spent sandblast material, sewage treatment plant effluent, and miscellaneous low volume wastes. The ash pond provides treatment by sedimentation, oxidation, neutralization, equalization, and adsorption. Descriptions of the individual historical waste streams are below. Currently no wastestreams are routed to the east ash pond. The dry areas of the ash pond may be treated with dust suppressant. Although all waste stream contributions to the ash pond have been eliminated, waste water remaining in the basin will continue to be removed through existing outfalls. As the water in the ash pond lowers, additional treatment may be brought onsite to ensure the ash pond discharge maintains compliance with NPDES permitted limits, such as a portable filtration unit. Ash Sluice Water Fly ash and bottom ash from both units were hydraulically conveyed by an ash sluice pipeline to the ash pond. As needed, alum was added to the ash sluice influent to aid settling. A Rotamie system was used to inject urea into Units 5 and 6. In the boiler, the ammonia/urea reacted with NOx to form water vapor and nitrogen. The system was designed to minimize any ammonia formation and ammonia slip. Any unreacted ammonia adsorbed on the fly ash from this system was carried to the ash pond via ash sluice water. Sanitary Waste Treatment Effluent Historically, sanitary wastes were treated at an extended aeration package plant prior to discharge to the East Ash Pond which provided secondary treatment for the effluent. Currently, sanitary wastes are treated in an onsite septic system permitted by Chatham County. Temporary, portable toilets are occasionally brought on site as needed to accommodate staffing levels. Miscellaneous Wastes Cooling tower basin sludge; residuals from the low volume wastes retention basin and coal pile retention basin; ash trench materials; circulating water tunnel sediment; boiler, electrostatic A3-2 Duke Energy Progress, Inc. NPDES Permit NCO003433 Cape Fear Steam Electric Plant 2014 Permit Application Amendment precipitator wash, spent sandblast material, air preheater wash, and other miscellaneous low volume wastes from plant process were also transported to the East Ash Pond. Outfalls SW -1, SW -2, SW -3, and SW -8 — Storm Water In 2011, Duke Energy Progress applied for an individual stormwater permit (prior to that, stormwater outfalls were included in the NPDES wastewater permit). During the permitting process, DEP and DENR concurred that since there is no industrial activity occurring onsite, the industrial stormwater permit is not applicable. DEP withdrew the permit application and NCDENR responded with a letter accepting the application withdrawal. Since 2013, the site has been further demolished and holds an approved Erosion and Sedimentation Control Plan, which subjects the site to the requirements of the Construction Stormwater General Permit. The following descriptions apply to the SW outfalls identified in DEP's 2011 application for an individual stormwater permit. Outfall SWA and Outfall SW -8 are legacy riser structures from inactive ash ponds. Discharges of stormwater from these outfalls are rare and NCDENR has concurred with the estimation that it would take greater than the 25 -year, 24- hour storm event to generate a discharge from these outfalls. Outfall SW -1 discharges directly into the Cape Fear River and Outfall SW -8 discharges into Shaddox Creek which flows into the Haw River just above the confluence with the Deep River which forms the Cape Fear River. Storm water collected along the railroad track between the plant entrance road and the plant site combines with the drainage of an open field which is directed via Outfall SW -2 into Shaddox Creek that flows into the Haw River just above the confluence with the Deep River. Historically, coal was moved along the railroad track, however coal is no longer brought onsite. There is currently no industrial activity occurring within this drainage area. Stormwater collected along the roadside swell beside the plant entrance road is directed via Outfall SW -3 towards drainages that go to Shaddox Creek. Historically this location was selected to capture potential impacts from an ash sluice line that crossed under the entrance road. Ash is no longer sluiced and the line has been physically disconnected. Other Wastes Herbicide Usage in the Treatment System Ponds Herbicides are used as needed to control nuisance aquatic vegetation.

(Progress Energy), a Subsidiary of Duke Energy Inc. Cape Fear Steam Electric Plant (NPDES NC0003433/NCS000550 draft) NPDES Storm Water Permit Application Withdrawal Dear Ms. Georgoulias; Progress Energy is hereby withdrawing the Cape Fear Steam Electric Plant NPDES Form 2F Application for Permit to Discharge Storm Water Discharges Associated with Industrial Activity submitted to Mr. Tom Belnick on December 2, 2010. This power plant has ceased all categorical industrial activity and no longer requires authorization to discharge storm water. The submitted Form 2F application requested authorization to discharge storm water from four outfalls: SW -001, SW -002, SW -003, and SW -008. As acknowledged in the draft individual storm water permit, there are no discharges from Outfalls SW -001 and SW -008 (inactive ash basins) for events less than a 25 year/24 hour storm, thus, these outfalls are not subject to storm water permitting. No more coal is being delivered to the power plant thus authorization for the drainage area along the rail spur, which discharges via Outfall SW -002, is no longer required. A de minims amount of coal remains along this short spur but this insignificant amount of material is not expected to cause any environmental impact. The ash sluice line crossing the swell at Outfall SW -003 is no longer in use. The line was rinsed and portions of the piping were removed on November 8, 2012, the last categorical activity to be ceased at the power plant. Progress Energy Carolinas.

Georgoulias Page 2 of 2 December 13, 2012 Because no categorical industrial activity is currently conducted at the Cape Fear Steam Electric Plant, no authorization for the discharge of storm water associated with industrial activity is required. Therefore, Progress Energy believes that the current NPDES storm water permitting requirements are no longer applicable. Please respond with concurrence of our understanding by either a letter to me at the power plant address or an email to Ms. Robin Bryson, Environmental Specialist in our corporate office, at robin.brvsonlanenmail.com. 1 certify, under penalty of low, that this document and oil 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. i am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations.

E , Director Division of water Quality October 12, 2005 RECEIVED OCT 17 200 CAPE FEAR PLANT Subject: NPDES Permit NCO003433 Cape Fear Steam Plant Wake County The Division evaluated your request to waive sampling requirements for the stormwater outfalls for the Cape Fear Steam Plant's renewal application. Five stormwater outfalls are covered under the NPDES permit, SW -1, SW -2, SW -3, SW -4, and 008. Outfalls SW -1 and 008 drain the area were the old ash ponds were located. The ponds have not been used for more than 30 years and are covered with vegetation. In this case the application requirements are not applicable because there is no exposed materials or industrial activity. Outfall SW4 drains an area near the railroad tracks and is tributary to outfall 007. Outfall 007 is the outfall at the discharge canal and is monitored and sampled under the permit. Outfall SW -4 is represented by outfall 007, therefore no sampling is necessary for the application. Outfalls SW -2 and SW -3 drain small areas from the road and railroad line and are combined with parking and grassy areas. As informed by Progress Energy, these outfalls do not collect enough flow to obtain a representative sample. The sampling and testing requirements for outfalls SW -2 and SW -3 are also waived for the permit renewal application. At this time the Division is not granting any modifications to the conditions pertaining to stormwater outfalls in the permit. Due to the proximity of the renewal date, modifications to the permit pertaining the elimination of outfalls shall be requested with the permit renewal application. If you have any questions please contact Teresa Rodriguez of the NPDES Unit at (919) 733-5083, extension 553.

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 the spring of 2014. Representative seep locations were evaluated for water quality and flow rates during late June to early July 2014. Wastewater discharges from the ash ponds 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 NC0003433. The purpose of the evaluation was to determine additional potential outfalls for inclusion within the permit. Fifteen seep locations were identified during wet weather conditions in early spring of 2014. However, only six locations contained sufficient water for water quality sample collection in late June to early July 2014. Seven of the sample locations were located upstream of the Outfall 007 to the canal on the property. The low volume of water characteristic of the seeps coupled with the relatively low constituent concentrations in the samples, suggest that there is little potential to influence water quality of Shaddox Creek or the Cape Fear River. If reasonable potential analyses demonstrate that there is 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 the Cape Fear River 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.

(Duke Energy) owns and operates the Cape Fear Steam Electric Plant (Cape Fear Plant) located on approximately 900 acres in central North Carolina near Moncure, North Carolina. The Cape Fear Plant is located in Chatham County along the east bank of the Cape Fear River southeast of Moncure and west of Corinth Road. The site location is shown on Figure 1. The Cape Fear Plant began operations in 1923 and additional units were added in the following years. Throughout its operational history, the Cape Fear Plant employed six coal-fired units along with four oil -fueled combustion turbine units to produce steam. Ash generated from coal combustion was stored on-site in ash management ponds. Operations were terminated at Cape Fear Plant in October 2012 and demolition activities are currently underway. Wastewater discharges from the ash ponds are permitted by the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality (DWQ) under National Pollution Discharge Elimination System (NPDES) Permit NC0003433. This report summarizes an evaluation of seepage flows across the Cape Fear Plant. 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 late February 2014. Seep sampling and flow measurements were completed from June 30 through July 2, 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 in June/July 2014. During the June/July evaluation, it was observed that some of the seeps identified in February 2014 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 June/July 2014 at water -bearing seep locations using either a Son -Tek F1owTracker ® 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 two locations where the flow was constrained in a location that prevented the F1owTracker from recording a signal without interference. The timed -volumetric method was employed by collecting a volume of water from the discharge 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. 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 the majority of seeps and in the Shaddox Creek stream channel. The method is designed for streams that can be waded following established procedures such as the U.S. Geological Survey standards. Use of the F1owTracker® 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 channel 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 discharge at a given location. Page 2 P: \ Duke Energy Progress.1026 \ Cape Fear \ Seep Monitoring Plan\ Cape Fear Seep Monitoring Plan 7-30-14.docx Seep Monitoring July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra If the channel width at the water line was between 1.0 and 2.5 feet, velocity and depth were recorded at a minimum of three locations spaced evenly across the channel. If the channel width was between 2.5 and 5 feet, velocity and depth were recorded at a minimum of five evenly spaced locations. An exception to the methodology occurred at the surface water location on Shaddox Creek because conditions made it unsafe to enter the stream and access five 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 June/July 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 Six seep locations with measurable flow, water from two ash ponds, and four surface water bodies were sampled during June/July 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 very low precipitation. For the approximate three weeks preceding the June/July sample collection, only 0.14 inches of rain fell in the area as recorded at the Raleigh Executive Jetport (Sanford, NC), located about three miles west-southwest of the Cape Fear 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, specific conductance) were measured utilizing a YSI Pro Plus multi -function meter. Turbidity was also measured in the field using a Hach 2100Q turbidimeter. In addition to seep samples collected from seeps, four samples were collected from the surface water bodies that bound the Cape Fear Plant. Three sample locations (Haw River and Cape Fear River) were accessed using a personal watercraft. The samples were collected at a midstream location as a grab sample from a depth of approximately one meter. The sample from Shaddox Creek was accessed from the shore. • A surface water sample was collected from the Haw River approximately 200 feet upstream of the northern Plant property line, upstream of Shaddox Creek, Page 3 P: \ Duke Energy Progress.1026 \ Cape Fear \ Seep Monitoring Plan\ Cape Fear Seep Monitoring Plan 7-30-14.docx Seep Monitoring July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra and upstream of the confluence of the Haw River with the Deep River that forms the Cape Fear River. • A surface water sample was collected from the Cape Fear River downstream of the Plant, approximately 300 feet upstream of the railroad trestle that crosses the river near Brickhaven, NC. • A surface water sample was collected from the Cape Fear River downstream near the NC Highway 42 bridge (Avents Ferry Road) upstream from the surface water intake located on the west side of the Cape Fear River. This location is approximately 300 feet upstream of the bridge and surface water intake. • A surface water sample was collected from Shaddox Creek on the north side of Corinth Road, north of the intersection of Corinth Road and CP&L Drive. This location is upstream of the Cape Fear Plant. Samples were also collected of the water in the 1978 and 1985 ash ponds. Laboratory analyses were conducted by Duke Energy's Huntersville 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 the Cape Fear River 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.

The flow coalesced into a single channel about 25 feet downslope from its emergent location.

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 <_6 °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 compositing procedures, see EPA Method 1664 Rev. A (oil and grease) and the procedures at 40 CFR 141.34(f)(14)(iv) and (v) (volatile organics). 3When 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 11, 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; Nitric 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 concentrations of 0.080% by weight or less (pH about 12.30 or less). 4Samples 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 specific types of samples under study, the analytes 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 time 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 time 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 time 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 that 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 date, the date of collection is the date on which the sample is collected. For a composite sample collected automatically, and that is collected across two calendar dates, the date 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. 5ASTM D7365 -09a specifies treatment options for samples containing oxidants (e.g., chlorine). Also, Section 9060A of Standard Methods for the Examination of Water and Wastewater (20th and 21st editions) addresses dechlorination procedures. 6Sampling, preservation and mitigating interferences in water samples for analysis of cyanide are described in ASTM D7365 -09a. There may be interferences that are not mitigated by the analytical test 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. 7For 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 Part 403, Appendix E), filter the sample within 15 minutes after completion of collection and before adding preservatives. If it 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 filter grab samples to be composited (footnote 2) in place of a composite sample collected automatically. 8Guidance applies to samples to be analyzed by GC, LC, or GC/MS for specific compounds. 91f the sample is not adjusted to pH 2, then the sample must be analyzed within seven days of sampling. 10The pH adjustment is not required if acrolein will not be measured. Samples for acrolein receiving no pH adjustment must be analyzed within 3days of sampling. 11When 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 necessary preservatives and hold for the shortest time listed). When the analytes of concern fall within two or more chemical categories, the sample may be preserved by cooling to 156 °C, reducing residual chlorine with 0.008% 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 thiosulfate reduction), and footnotes 12, 13 (regarding the analysis of benzidine). 121f 1,2-diphenylhydrazine is likely to be present, adjust the pH of the sample to 4.0 t0.2 to prevent rearrangement to benzidine. 13Extracts may be stored up to 30 days at <0 °C. 14 For the analysis of diphenylnitrosamine, add 0.008% Na2S2O3 and adjust pH to 7-10 with NaOH within 24 hours of sampling. 15The 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% Na2S2O3. 16 Place sufficient ice with the samples in the shipping container to ensure that 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-site 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 -delivered samples used on the day of collection do not need to be cooled to 0 to 6 °C prior to test initiation. 17 Samples collected for the determination of trace level mercury (<100 ng/L) 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 time to preservation 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 time 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. 18Aqueous samples must be preserved at _<6 °C, 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 of NPDES monitoring, the specification of "<°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 specified so that rounding down to 6 °C may not be used to meet the :56 °C requirement. The preservation temperature does not apply to samples that are analyzed immediately (less than 15 minutes). 19An 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 footnote 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. 20To achieve the 28 -day holding time, use the ammonium sulfate buffer solution specified in EPA Method 218.6. The allowance in this 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. 21Holding 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 filtration to elution for samples filtered in the field. 22 Sample analysis should begin as soon as possible after receipt; sample incubation must be started no later than 8 hours from time of collection. 23 For fecal coliform samples for sewage sludge (biosolids) only, the holding time is extended to 24 hours for the following sample types using either EPA Method 1680 (LTB -EC) or 1681 (A-1): Class A composted, Class B aerobically digested, and Class B anaerobically digested. 24 The immediate filtration requirement in orthophosphate measurement is to assess the dissolved or bio -available form of orthophosphorus (i.e., that which passes through a 0.45 -micron filter), hence the requirement to filter the sample immediately upon collection (i.e., within 15 minutes of collection).

(Duke Energy) requirement for groundwater monitoring around the Cape Fear Steam Electric Plant (Cape Fear Plant) ash management area operated under NPDES Permit NC0003433. 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 Cape Fear Plant ash management area groundwater monitoring program. Page 1 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 2.0 SITE DESCRIPTION 2.1 Plant and Ash Management Areas Duke Energy Progress, Inc. owns and operates the Cape Fear Steam Electric Plant (Cape Fear Plant) located on approximately 900 acres in central North Carolina near Moncure, North Carolina. The Cape Fear Plant is located in Chatham County along the east bank of the Cape Fear River southeast of Moncure and west of Corinth Road. The site location is shown on Figure 1. The Cape Fear Plant began operations in 1923. Additional units were added from 1924 to 1969. Throughout its operational history, the Cape Fear Plant employed various combinations of six coal-fired units along with four oil -fueled combustion turbine units to produce steam. Ash generated from coal combustion was stored on-site in ash management ponds. Operations were terminated at the Cape Fear Plant in October 2012 and demolition activities are currently underway. 2.2 Ash Management Area Description Ash generated from coal combustion throughout the operational history of the Plant was stored in on-site ash management ponds. Throughout most of its history, ash was conveyed as a slurry to the ash ponds. Five ash management ponds have historically been used at the Cape Fear Plant and are referenced using the date of construction: 1956, 1963, 1970, 1978, and 1985. The 1956 ash pond is located north of the former power plant, and the remaining ash ponds are located south of the power plant area. The 1963 and 1970 ash ponds were constructed on the west side of the Plant property adjacent to the Cape Fear River. The 1978 ash pond was constructed east of and abutting the 1963 and 1970 ash ponds. The 1985 ash pond was constructed east of the existing ash ponds between the discharge canal and Corinth Road. The ash ponds are impounded by earthen dams. A 500 -foot compliance boundary encircles the ash management areas. The ash pond locations are indicated on Figure 2. Currently, the 1956, 1963, and 1970 ash ponds are entirely covered with vegetation (both hardwood and pine trees). No free-standing water is present in the 1956 or 1963 ash ponds. Only a very small area near the southern end of the 1970 ash pond is seasonally wet. The 1978 ash pond is partially vegetation -covered (both trees and scrub), and a portion of the southern end of the ash pond retains water. The 1985 ash pond has some grass cover and ponded water in the southwest corner of the ash pond.

Permitted outfall locations are indicated on Figure 2. Page 3 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 3.0 SITE GEOLOGY AND HYDROGEOLOGY 3.1 Geologic Framework Topographically, the Cape Fear Plant is situated in the Piedmont plateau region of central North Carolina, only a few miles north and west of the contact between the Piedmont and the North Carolina Coastal Plain. The Piedmont is characterized by well- rounded hills and rolling ridges. Elevations in the area of the Cape Fear Plant are between 150 and 200 feet above mean sea level. Geologically, the Plant is located within the Deep River Basin (specifically the northern portion of the Sanford Sub -basin), an irregular, half graben structural feature of Triassic age. In the area of the Plant, the basin is surrounded by and presumably underlain by igneous and metamorphic rocks of the Carolina Terrane (formerly Carolina Slate Belt) rocks. Over time, continental sediments filled the basin to great thicknesses and have subsequently been cut by numerous diabase dikes. The stratigraphy of the basin, consistent with other basins in North Carolina and Virginia, is represented by a lower sequence of coarse-grained arkosic sandstone and conglomerate; a middle sequence of siltstone, shale, and thin coal deposits; and an upper sequence of sandstone, mudstone, siltstone, and conglomerate. In general, the strata of the Deep River Basin dip gently to the east (Horton and Zullo, 1991). According to the Geologic Map of North Carolina (1985), the Cape Fear Plant is situated within the rocks of the Pekin Formation of the Chatham Group; although, the Plant appears to be situated just at the gradational contact of the Pekin Formation with the Cumnock Formation. The Geologic Map of North Carolina describes each of these units as being comprised of fluvial sedimentary rocks such as conglomerate, sandstone, and mudstone. These general observations are consistent with site-specific observations from drilling activities at the Cape Fear Plant, which generally describe the sedimentary rocks underlying the Plant as brown to gray mudstones and siltstones. Rocks of the Piedmont, 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 Cape Fear Plant confirm the presence of residuum, developed above the sedimentary rocks of the Plant area, that is generally 15 to 30 feet thick and extends from the ground surface to the contact with rock. 3.2 Hydrogeologic Framework Groundwater within the Piedmont exists under unconfined, also known as water table, conditions within the residuum and/or saprolite zones and in the fractures and joints of Page 4 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra the underlying bedrock. The water table and bedrock aquifers are interconnected. The residuum acts as a reservoir for water supply to the fractures and joints in the underlying 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 may serve as groundwater recharge zones. 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 closest surface water discharge for the subject property occurs to the west as small, perennial and intermittent streams and creeks flow toward and discharge to the Cape Fear River, a large regional river. The predominant flow direction for groundwater is to the west and west-southwest. Groundwater beneath the Plant area occurs within the residuum at depths ranging from about 10 feet to about 20 feet below the ground surface. Depths to groundwater in wells completed in the shallow bedrock are similar. Groundwater elevations from paired wells typically show slight downward vertical gradients in upland areas and an upward gradient near the Cape Fear River. Analysis of potentiometric data for Plant wells confirms that groundwater flows from upland areas located east of the Plant towards the west-southwest with discharge to the Cape Fear River. The approximate groundwater gradient for June 2014 data was 10.55 feet (vertical change) over 4,200 feet (horizontal distance) or 2.5 feet/1,000 feet as measured from upgradient well CMW-5 to downgradient well CMW-1.

Cape Fear operates under NPDES Permit NC0003433 (effective September 1, 2011) which authorizes discharge as follows: • West Ash Pond (Internal Outfall 001L- This outfall discharges the following treated wastewaters to outfall 007: ash sluice waters (bottom and fly), coal pile runoff, No. 2 fuel oil tank runoff, settling basin drains, sand bed filter backwash, parking lot drains, equipment cooling tower blowdown and drain, boiler blowdown, metal cleaning waste, oil unloading area drains, softener regenerate, demineralizer regenerate, acid/caustic sump wastewater, yard and floor drains, and ash trench drain wastewater. • Once -Through Cooling Water and Stormwater (Internal Outfall 003). • East Ash Pond (Internal Outfall 005): This outfall discharges the following wastewaters to outfall 007: ash sluice waters (bottom and fly), runoff from yard drains, air preheater washes, electrostatic precipitator washes, metal cleaning wastes, spent sandblast material, and treated sanitary wastewater. • Combined Wastewater to the Cape Fear River (Outfall 007): This outfall is a combination of all internal outfalls. In addition to surface water monitoring, the NPDES permit requires groundwater monitoring. Permit Condition A (6) Attachment XX, Version 1.0, dated March 30, 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 Cape Fear Plant ash management area 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. Page 6 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra In accordance with the March 30, 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 groundwater monitoring plan for the Cape Fear Plant includes the sampling of 13 wells. These 13 wells include two background wells and 11 downgradient wells. The locations of the monitoring wells, the waste boundary, and the compliance boundary are shown on Figure 2. Well construction data 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 is to the west and southwest, toward the Cape Fear River. The site wells provide monitoring data for the groundwater downgradient of the ash management area. The compliance monitoring network includes two background monitoring wells, BGMW-4 and BGTMW-4, one upgradient compliance boundary monitoring well, CMW-5, plus 10 monitoring wells located in side -gradient and downgradient positions along the compliance boundary. Wells BGTMW-4, CTMW-1, CTMW-2, CTMW-7, and CTMW-8 were installed in the upper bedrock and were paired with shallow wells BTMW-4, CMW-1, CMW-2, CMW- 7, and CMW-8, 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, CMW-3, CMW-5, and CMW-6, were installed in the saprolite or residuum, above bedrock. Groundwater monitoring for the compliance wells began in December 2010. 4.3 Monitoring Frequency The monitoring wells will be sampled three times per year in March, June, and October. 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. Page 7 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra The analytical results for the detection monitoring program will be compared to the NC 2L Standards or the site-specific background concentrations. 4.5 Data Quality Objectives The overall Quality Assurance (QA) objective is to ensure that reliable data of known and acceptable quality are provided. 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 8 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 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, 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 9 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan \ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 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 Cape Fear 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 Cape Fear Plant, low -flow sampling is conducted using a peristaltic 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 two pH standards (pH 7.0 and 4.0) bracketing the expected groundwater pH. The specific conductance subsystem is calibrated using two Page 10 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan\ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra standards bracketing the expected groundwater conductivity. 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 Chain -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).

Additionally, a Groundwater Sampling Site Checklist (Figure 7), or equivalent, is completed indicating information about the monitoring wells such as proper identification (ID) tag and condition of protective casing and pad. Field notations shall be made during the course of the field work to document the following information: • Identification of well • Well depth • Static water level depth and measurement technique • Well yield - high or low • Purge volume or pumping rate • Sample identification numbers • Well evacuation procedure/equipment • Sample withdrawal procedure/equipment • Date and time of collection • Types of sample containers used • Identification of replicates or blind samples • Preservative(s) used • Parameters requested for analysis • Field analysis data and methods • Sample distribution and transporter • Field observations during sampling event • Name of sample collector(s) • Climatic conditions including estimate of air temperature The Groundwater Monitoring Data Sheet, Field Sampling Calibration Form, and COC Record and Analysis Request Form will be filed by project and date. Recorded entries will be made on electronic forms or on paper forms in indelible ink. Errors on paper documents will be corrected by drawing a line through the error, initialing and dating the correction, and starting a new entry on the next line (if necessary). Page 12 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan\ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 5.8 Chain -of -Custody Record The COC Record (Figure 6) accompanies the sample(s), traces sample possession from time of collection to delivery to the laboratory(s), and clearly identifies which sample containers have been designated for each requested analysis. The record includes the following types of information: • Sample identification number • Signature of collector • Date and time of collection • Sample type (e.g., groundwater, immiscible layer) • Identification of well • Number of containers • Parameters requested for analysis • Preservative(s) used • Signature of persons involved in the chain of possession • Inclusive dates of possession 5.9 Sample Custody, Shipment, and Laboratory Receipt For the purpose of these procedures, a sample is considered in custody if it is: • In actual possession of the responsible person • In view, after being in physical possession • Locked or sealed in a manner so that no one can tamper with it after having been in physical custody or in a secured area restricted to authorized personnel. Samples shall be maintained in the custody of the sampling crew during the sampling event. At the end of each sampling day and prior to the transfer of the samples off site, entries shall be completed on the COC form for all samples. Upon transfer of custody, the COC form is signed by a sampling crew member, including the date and time. If outside vendor laboratories are utilized, samples shall be delivered to these facilities by Duke Energy personnel or courier. COC forms received by the laboratory(s) shall be signed and dated by the respective supervising scientist(s) or their designee (at the Duke Energy Analytical Lab Services lab) or the laboratory sample custodian (at vendor labs) immediately following receipt by the laboratory. The analysts at the laboratory(s) maintain a sample tracking record Page 13 P:\Duke Energy Progress. 1026 \Cape Fear\GW Sampling and Analysis Plan\Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra that will follow each sample through all stages of laboratory processing. The sample tracking records show the date of sample extraction or preparation and analysis. These records are used to determine compliance with holding time limits during lab audits and data validation. Custody procedures followed by Duke Energy Analytical Lab Services laboratory personnel are described in detail in the Duke Energy Analytical Lab Services Procedures Manual. Page 14 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan\ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 6.0 ANALYTICAL PROCEDURES The main analytical laboratory used in this program is the Duke Energy Analytical Laboratory Services: N.C. Drinking Water (NC37804) and Wastewater (#248) Certifications. The organizational structure and staff qualifications of the laboratory are discussed in its generic Quality Assurance Program (QAP). The QAP and the Analytical Laboratory Procedures Manual are available for review upon request. Vendor laboratories that meet EPA and North Carolina certification requirements may be used for analyses with approval by Duke Energy. The analytical procedures used for the samples analyzed for this Groundwater Monitoring Program are listed in Table 2. Specific conductance, field pH, and temperature are measured in the field according to the Duke Energy Groundwater Monitoring and Sample Collection Procedure or the instrument manufacturer instructions. Page 15 P: \ Duke Energy Progress.1026 \ Cape Fear \ GW Sampling and Analysis Plan\ Cape Fear GW Monitoring Plan 7-30- 2014.docx Groundwater Monitoring Program July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 7.0 INTERNAL QUALITY CONTROL CHECKS Internal laboratory quality control (QC) checks used by the laboratories are described in each laboratory's generic QAP and procedures manual. 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.

(Duke Energy) owns and operates the Cape Fear Steam Electric Plant (Cape Fear Plant) located on approximately 900 acres in central North Carolina near Moncure, North Carolina. The Cape Fear Plant is located in Chatham County along the east bank of the Cape Fear River southeast of Moncure and west of Corinth Road. The site location is shown on Figure 1. The Cape Fear Plant began operations in 1923 and additional units were added in the following years. Throughout its operational history, the Cape Fear Plant employed six coal-fired units along with four oil -fueled combustion turbine units to produce steam. Ash generated from coal combustion was stored on-site in ash management ponds. Operations were terminated at the Cape Fear Plant in October 2012 and demolition activities are currently underway. Wastewater discharges from the ash ponds 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 NC0003433. 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 Cape Fear Plant ash management area compliance boundary (Figure 2). The compliance boundary for groundwater quality in relation to the ash management area 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. Page 1 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 2.0 BACKGROUND 2.1 Plant Description The Cape Fear Plant began operations in 1923 and additional units were added in the following years. Six coal-fired units, in combination with four oil -fueled combustion turbine units, were employed throughout the operational history of the plant to produce steam. Ash generated from coal combustion was stored on-site in ash management ponds that were constructed in 1956, 1963, 1970, 1978, and 1985. Operations were terminated at Cape Fear Plant in October 2012 and demolition activities are currently underway. Wastewater discharges from the ash ponds are permitted by the NCDENR under NPDES Permit NC0003433. The permit allows for the discharge of wastewater at four outfalls to an "unnamed tributary to the Cape Fear River'. Upstream of the Outfall 007 the water body is referred to as the "Canal". Downstream of Outfall 007 it is referred to as "Unnamed Tributary". Outfall 001 is an internal outfall from the "West Ash Pond" (1978 ash pond). Outfall 003 is an internal outfall from once -through cooling water and stormwater. Outfall 005 is an internal outfall from the "East Ash Pond" (1985 ash pond). Outfall 007 is a combination of all of the internal outfalls. 2.2 Description of Surrounding Properties Properties within a 0.5 mile radius of the Cape Fear Plant compliance boundary are located in southeastern Chatham County and eastern Lee County, North Carolina. Lee County, located west of the Cape Fear Plant, is physically separated from the Cape Fear Plant by the Haw, Deep, and Cape Fear Rivers. The Deep and Haw Rivers come together northwest of the Cape Fear Plant property to form the Cape Fear River. Property uses within the 0.5 mile radius include residential, recreational, industrial, and agricultural. Figure 2 depicts the properties surrounding the Cape Fear Plant. Page 2 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 3.0 RECEPTOR SURVEY ACTIVITIES 3.1 NCDENR Records Review SynTerra reviewed the NCDENR Department of Environmental Health (DEH) Public Water Supply Sections (PWSS) Public Water Supply Water Sources Geographic Information System (GIS) point data set (pwsws.shp) and the Water Distribution Map Service (WDMS) data set obtained from the NC OneMap GeoSpatial Portal (http://data.nconemap.com/geoportal/catalog/main/home.page) to identify public water supply sources and water supply lines within a 0.5 mile radius of the Cape Fear Plant compliance boundary. 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 June 24, 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 wellhead protection areas located within a 0.5 mile radius of the compliance boundary. The NCDENR SWAP database provides detailed assessments of 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 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 2. A copy of the EDR report is included as Appendix A. 3.3 USGS Hydrography Review SynTerra reviewed the United States Geological Survey (USGS) National Hydrography Dataset (NHD) obtained from the USGS National Map Viewer (http://viewer.nationalmap.gov/viewer/) to identify surface waters within a 0.5 mile radius of the compliance boundary. Page 3 P:\Duke Energy Progress.1026\Cape Fear\Receptor Survey\Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 3.4 SynTerra Field Survey During February, March, and April 2014, SynTerra personnel conducted vehicular surveys along public roads located within 0.5 mile of the compliance boundary. Observations on property use, apparent proximity to available municipal water lines, and structures that may represent potential water supply wells were noted. Field observations were checked against parcel ownership information available through the Chatham County and Lee County on-line GIS databases. The GIS websites for both Chatham County and Lee County were reviewed for water line information. The presence of water lines managed by Chatham County Utilities & Water Division was noted in the area of Cape Fear Plant; although, for a number of residences, both a possible water well structure and the presence of a water line were observed. Mr. Leonard McBryde (Chatham County Utilities & Water Division) was contacted for information about which residences were connected to municipal water lines. Mr. McBryde declined to provide the requested information and referred any further inquiries to the County's attorney. SynTerra made no further attempt to acquire public water use information. Municipal water lines do not serve the area of Lee County included in this water well survey. 3.5 Previous Water Supply Well Survey Information The results of a previous receptor survey conducted by Geosyntec Consultants in November 2013 have been incorporated into the findings of this report. Page 4 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra 4.0 FINDINGS 4.1 NCDENR Records No public water supply wells were identified in the Public Water Supply Water Sources GIS point data set (obtained from NC OneMap GeoSpatial Portal) or on the NCDENR SWAP online database within a 0.5 mile radius of the ash management area compliance boundary. No wellhead protection areas were identified on the NCDENR SWAP online database within a 0.5 mile radius of the compliance boundary. 4.2 Environmental Data Resources, Inc. Records A review of public database information provided by Environmental Data Resources, Inc. (EDR) was also conducted. No water wells or public water supply systems within a 0.5 mile radius of the compliance boundary were noted in the EDR report. A copy of the EDR report is included as Appendix A. 4.3 USGS Hydrography Review The Cape Fear Plant is bounded on the west by the Haw River and the Cape Fear River. The Haw River bounds the property from its confluence with Shaddox Creek south to its confluence with the Deep River, a distance of about 1,200 feet. The Haw River and Deep River come together to form the Cape Fear River which extends along the western side of the Cape Fear Plant property for about two miles (river distance). The Haw, Deep, and Cape Fear Rivers flow south. Shaddox Creek is a perennial stream that flows generally from northeast to the west and enters the Cape Fear Plant property in the northeast corner of the property, eventually discharging to the Haw River. Several small intermittent streams enter the property from the northeast and east and flow through in the eastern and southern part of the property, eventually discharging to the "canal". A small stream flows through the southern portion of the property and discharges to the Cape Fear River. The unnamed tributary partially discharges to the Cape Fear River at the southern end of the property and also continues to the south to Buckhorn Dam. Two perennial streams (Womble's Creek and Little Shaddox Creek) are indicated on the west side of the Cape Fear River in Lee County. 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. Structures resembling water supply wells or well houses were noted where visible and are shown Page 5 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra on Figure 2 as reported/observed water supply wells (DW). Observations related to the survey area are presented below: Corinth Road (North of Cape Fear Plant) - Chatham County. This area is upgradient of the compliance boundary. A municipal water line is located along Corinth Road. Three large industrial facilities are located north of Cape Fear Plant along Corinth Road. No wells were observed. • Corinth Road (East/Southeast of Cape Fear Plant) - Chatham County. This area is upgradient of the compliance boundary. A municipal water line is located along Corinth Road. Two residences are located within or very near to the 0.5 mile distance from the compliance boundary (east/southeast) that appear to have water well structures. An additional three occupied residences and one unoccupied property are located just outside of the 0.5 mile distance and were observed to have suspected water well structures. For these properties, direct visual observation of a structure likely housing a water well was made. Depending on the installation date for the municipal water line that runs along Corinth Road, it appears that private water supply wells may have been in use prior to the installation of municipal water lines for most residences. • River Point Road (Northwest of Cape Fear Plant) - Chatham County. River Point Road is located on the northwest (far) side of the Haw River and upgradient of the compliance boundary. River Point Road is serviced by a municipal water line. Occupied residential properties are located along River Point Road. The area is bounded on the east by the Haw River, on the west by the Deep River and on the south by the confluence of these rivers into the Cape Fear River. One property within the survey area appears to have a structure that may contain a water well. A municipal water line and water meters were observed for the residences. • Nottingham Lane/Farmington Lane (West of Cape Fear Plant) - Lee County. This area is located on the west side of the Cape Fear River which is a large, regional hydraulic boundary for groundwater; therefore, the area is not within the shallow groundwater flow path of the Cape Fear Plant. Thirteen residences are located in Lee County, North Carolina within or near approximately 0.5 miles of the compliance boundary. There are no municipal water lines in the area; therefore, it is assumed that occupied residences are served by water wells. • Surface Water Intakes. Two surface water intakes were noted during field reconnaissance activities (Figure 2). A surface water intake on the Cape Fear River, located west of the power plant, was historically used for plant operations. Page 6 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra Currently, water from this intake is periodically used for dust control during site demolition work. Drinking water is not supplied by the intake. Beyond the survey area, an active surface water intake is located on the Cape Fear River approximately 2.5 miles downstream of the Cape Fear Plant. The intake structure is located near the west bank of the river where NC Highway 42 (Avents Ferry Road) crosses the Cape Fear River. This intake is maintained by the City of Sanford/Lee County Water Utilities Division and is the primary water supply for the Sanford and Lee County area (according to information on the City of Sanford Public Works website). 4.5 Summary of Geosyntec Survey Findings A receptor survey conducted by Geosyntec Consultants (November 2013) focused on an area within 1,500 feet of the compliance boundary and included a search for potential water supply wells, surface water bodies, and wetlands. The survey identified a total of 14 properties that appeared to have a structure that indicated the presence of a water supply well within 1,500 feet of the compliance boundary. The survey identified three surface water features: the Haw River, the Cape Fear River, and the Deep River. The survey identified 11.6 acres of freshwater emergent wetlands, 11.3 acres of freshwater ponds, and 366 acres of freshwater forested/shrub wetlands with 1,500 feet of the compliance boundary. 4.6 Summary of Receptor Survey Findings A summary of the receptor survey findings is provided below. Assumed and observed water supply well locations are shown on Figure 2. The well locations are numbered on the map to cross-reference information provided in Table 1. The table summarizes property location and owner information where a water supply well may be present. • No drinking water wells were identified downgradient of the compliance boundary. • No wellhead protection areas were identified within a 0.5 mile radius of the compliance boundary. • Approximately 20 possible water supply wells were observed, or are assumed to be located, within 0.5 mile radius of the compliance boundary, but each well location is either upgradient of the compliance boundary or across a regional groundwater divide (Haw and Cape Fear Rivers). Page 7 P:\Duke Energy Progress.1026 \ Cape Fear \ Receptor Survey \ Cape Fear Receptor Survey 7-30-14.docx Receptor Survey July 2014 Cape Fear Steam Electric Plant, NPDES Permit # NC0003433 SynTerra • A number of surface water features are present within the 0.5 mile radius of the compliance boundary. The surface water features flow toward the Cape Fear River which bounds the Cape Fear Plant on the west for a distance of about two miles, flowing south. • One former surface water intake is located adjacent to the Plant and is only used for dust control during ongoing site demolition activities.

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. TC3887529.1s Page 1 GEOCHECe - 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 surficial 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.

TC3887529.1s Page 2 GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY HYDROLOGIC INFORMATION Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic 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. Refer to the Physical Setting Source Map following this summary for hydrologic information (major waterways and bodies of water).

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 downgradient sites might be impacted. AQUIFLOW® 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 TC3887529.1s Page 3 GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY 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.
