Attachment 3 July 2014 Administrative Update
Form 2C - Item II -B Flow, Sources of Pollution, and Treatment Technologies
The Asheville Steam Electric Plant is located in Arden, North Carolina south of Asheville, North
Carolina. The plant has been in operation since 1964 and produces enough electricity to
supply approximately 150,000 average houses. The Asheville Steam Electric Plant is a coal -
fired, steam cycle electric generating plant with two coal -fired generating units. Two Internal
Combustion (IC) Turbines are also located on the plant site. The plant has a 320 -acre cooling
lake (Lake Julian) on the east side of the French Broad River in Buncombe County, North
Carolina
Chemical constituents contained in the discharges from this plant 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 this 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.
Outfall 001 - Discharge from Ash Pond or Lined Rim Ditch to French Broad River
The Plant's ash pond (hereinafter referred to as the 1982 ash pond), is located east of the
French Broad River, south of the plant and discharges into the French Broad River. As of July
2014, the 1982 ash pond is being excavated for material to be used in a lined, structural fill
project at the Asheville airport. To facilitate that process, Duke engineered and constructed a
temporary lined rim ditch with the full knowledge and approval of the North Carolina Division of
Water Resources to temporarily process wastewater generated while the 1982 ash pond was
being excavated. The lined rim ditch is located within the area of the 1964 ash pond.
Additionally, with the approval of the North Carolina Department of Environment and Natural
Resources, Duke relocated treated waters from the 1982 ash pond and lined rim ditch to a new
outfall location on the French Broad River. This relocation was necessary to allow for
enhancement to the dam of the 1964 ash pond to bring it up to current engineering standards.
The ash pond and /or rim ditch receives ash sluice water, various low volume wastes, coal pile
runoff, limestone pile runoff, gypsum pile runoff, air pre- heater cleaning water, fire protection

National Pollutant Discharge Elimination System Permit Number NC0000396
system drainage, chemical metal cleaning wastes, reverse osmosis system reject water, storm
water and other waters from the Combustion Turbine Facility on the Plant's site. Wastewater
from the plant's truck wash and weigh stations also are directed to the plant's 1982 Ash Pond or
rim ditch. Accumulated water within the boundaries of the 1964 ash pond may also be
transferred to the 1982 pond rim ditch or directly to outfall 001. Water levels in the 1964 pond
will be maintained below a maximum elevation identified for dam safety concerns. Water from
the 1964 ash pond is directed to outfall 001 as needed to maintain the water level below the
required elevation. The ash ponds and/or rim ditch provides treatment by sedimentation and
neutralization to the above - referenced individual waste streams. Water leaves the 1982 ash
pond and /or rim ditch via a standpipe with skimmer and flows by pipe to a lined secondary
settling basin via either the 1964 ash pond or via direct discharge by pipe, where it is then
discharged by overflow to a pipe that coveys it to the French Broad River. Toe drains from both
the 1982 pond and the 1964 ash pond drain to the French Broad River. Detailed descriptions of
the individual waste streams are below. Additionally, a detailed map with the location of various
seeps on the property is being provided as part of this permit application.
Ash Sluice Water
Fly ash and bottom ash from both units are hydraulically conveyed by an ash sluice pipeline to
the ash pond and /or lined rim ditch. As needed, alum and /or other chemical flocculants and
coagulants may be added to the ash sluice influent to aid settling. A Selective Catalytic
Reduction system (SCR) is operated on both Unit 1 and Unit 2 for NOx emissions control. Urea
is injected to reduce NOx emissions. A byproduct of this process is an "ammonia slip" which will
be carried to the 1982 ash pond and /or lined rim ditch via ash sluice water. As necessary, a
system to mitigate SO3 emissions may also inject additional ammonia into the combustion
process. This mitigation system has not been needed to date but may become necessary as
fuel sources change. Various wastewater boiler sediments and ash accumulations from
wastewater processes collected during maintenance activities may also be physically
transported to the 1982 ash pond and /or lined rim ditch. The ash pond and /or lined rim ditch
discharge combines with the FGD treated wastewater and flows into the secondary settling
pond prior to discharging to the French Broad River. With the approval of the North Carolina
Division of Water Quality, Duke Energy Progress, Inc. relocated this secondary settling pond
and discharge point to facilitate modifications designed to enhance the 1964 ash pond dam's
safety factor. Plans are being developed to potentially retrofit the electric generation units to
handle fly ash as a dry material to be disposed of in a landfill or reused in a beneficial reuse

project. This retrofit may be completed during the term of the next permit. Bottom ash may
continue to be handled wet or may be converted to a system considered to be dry handling
system by EPA.
Coal Pile Runoff
Storm water runoff from the coal pile is collected in drainage ditches that surround the coal pile.
The drainage ditches are routed to the 1982 ash pond or lined rim ditch for treatment. During
maintenance activities, sludges removed from catch basins, sumps, etc. may be transported to
either the 1982 ash pond, lined rim ditch or the 1964 ash pond for disposal.
Limestone and Gypsum Piles Runoff
Storm water runoff from the limestone and gypsum piles is collected in drainage ditches which
are routed to the 1982 ash pond or lined rim ditch for treatment. During maintenance activities,
sludges removed from catch basins, sumps, etc. may be transported to the 1964 ash pond,
lined rim ditch and /or the 1982 ash pond for disposal.
IStorm Water
Storm water runoff from the plant area, parking lots, combustion turbine area, oil storage and
handling facility and the plant's substations is routed to the ash ponds and /or lined rim ditch for
treatment. During maintenance activities, sludges removed from catch basins, sumps, etc. may
be transported to the 1964 ash pond, lined rim ditch, and /or the 1982 ash pond for disposal.
Low Volume Wastes
Boiler water make up is withdrawn from Lake Julian and purified utilizing vendor supplied
equipment. Boiler water is treated with ammonia, hydrazine, and sodium hydroxide. Boiler
blowdown and drainage is sent to the ash pond and/or lined rim ditch and may contain small
quantities of the chemicals. A new Reverse Osmosis system or alum coagulation /filtration
service is used in conjunction with the vendor supplied equipment to provide water for various
plant processes. The reject stream from the Reverse osmosis unit is sent to the 1982 ash pond
and /or lined rim ditch. Some molybdate waste from the closed cooling water system is created
through valve leakage and maintenance activities and is discharged to the 1982 ash pond
and /or lined rim ditch. A furnace ash hopper seal is maintained by using plant service water. A
standard operation water level is maintained in a seal trough for the ash hopper seal. Overflow

National Pollutant Discharge Elimination System Permit Number NC0000396
from this trough is discharged to the 1982 ash pond and/or lined rim ditch. A sodium hydroxide
solution is fed into this flow stream as necessary for ash pond /rim ditch pH adjustment. Sulfuric
acid is fed to the ash sluice water as necessary for 1982 ash pond and/or rim ditch pH
adjustment to comply with NPDES permit requirements. Coal dust suppression is achieved by
spraying a proprietary chemical on coal at different stages of coal use. Small amounts of
excess dust suppression chemical have the potential to be discharged to the 1982 ash pond
and /or lined rim ditch via plant drains or coal pile runoff. Small amounts of urea waste from bulk
urea unloading operations are discharged to the 1982 ash pond and/or lined rim ditch. All plant
area floor drains are routed to the 1982 ash pond and /or lined rim ditch and include equipment
drainage and wash down along with rainfall runoff. During maintenance activities sludges
removed from catch basins, sumps, etc. may be transported to the 1982 ash pond, the lined rim
ditch, and /or the 1964 ash pond for disposal.
In many cases, added chemicals are consumed or chemically altered during the plant
processes. Only trace amounts might be recoverable in water entering the 1982 ash pond
and /or lined rim ditch. Detectable levels of these chemicals would not be expected to occur in
ash pond or rim ditch discharges.
Flue Gas Desulfurization Blowdown (Low Volume Waste)
The Flue Gas Desulfurization (FGD) system directs flue gas into an absorber where a limestone
(calcium carbonate) slurry is sprayed. Sulfur dioxide in the flue gas reacts with the limestone to
produce calcium sulfate (gypsum). This system reclaims any unreacted limestone slurry to be
reused in the absorber. A small blowdown stream is used to maintain the chloride concentration
in the reaction tank. The blowdown stream is passed through a clarifier to remove solids and
the chloride concentration in the waste stream is diluted using water from Lake Julian.
Chemicals are used to adjust pH and to aid solids removal in the clarifier. A constructed
wetland is used to remove metals, mercury and selenium specifically, and the treated
wastewater is discharged into the secondary settling pond. To facilitate possible closure of the
1964 pond, the wetland treatment cells may be discontinued and any additional necessary
treatment constructed to treat FGD wastewater after the physical chemical treatment system.
The treatment necessary will largely be dependent on the final steam electric effluent guidelines
currently projected to be finalized in September, 2015.
Air Preheater Cleaning (Low Volume Waste)
4 It 2014

Duke Energy Progress, Inc.
Asheville Steam Electric Plant
National Pollutant Discharge Elimination System Permit Number NC0000396
The air preheater will be water washed once per year or more frequently as needed. The
wastewater from this activity will be discharged to the 1982 ash pond or lined rim ditch.
' Chemical Metal Cleaning Wastes
The boilers are chemically cleaned every five -to -eight years using tetraammonia ethylene
' diamine tetraaccetic acid (EDTA) solution. This cleaning solution and its rinses are stored on
site for disposal by evaporation in an operating unit's furnace. Typical cleanings would result in
a waste of approximately 80,000 gallons. Should evaporation not be used, the wastewater can
be treated by neutralization and precipitation prior to being conveyed to the 1964 ash pond, or
' to the 1982 ash pond and /or lined rim ditch, or other means of disposal. Cleaning of other heat
exchanger surfaces may produce 5,000- 10,000 gallons of wastewater every three -to -five years.
Other Low volume Wastes
Operation of the combustion turbine (CT) generation facility may produce turbine blade wash
water, inlet filter cooling water, various condensate waters, and water from equipment and tank
drains. These wastewaters will be collected in the storm water collection system of the CT site
and routed to the 1982 ash pond and /or lined rim ditch. During maintenance activities, sludges
removed from catch basins, sumps, etc. may be transported to the 1964 ash pond, the 1982
ash pond, and/or the lined rim ditch for disposal.
Plant Potable and Sanitary System
The supply of water for plant potable and sanitary use is obtained from the Asheville /Buncombe
Water Authority system and waste from this system is discharged to the Metropolitan Sewage
District System.
Herbicide and Pesticide Usage in the Treatment System Ponds
Herbicides may be used as needed to control nuisance aquatic vegetation. These herbicides
are applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator. Pesticides may be used as needed including the performance of biological
assessments. The pesticides will be applied in accordance with the Pesticide General Permit
NCG560000, where applicable, and the manufacturer's instructions.

230 KV Substation Storm Water
Storm water runoff from the substation located adjacent to the plant is conveyed to the 1964 ash
pond. This water may be transferred to the 1982 ash pond and /or the lined rim ditch as needed
to maintain appropriate water levels in the 1964 ash pond.
Outfall 002 - Discharge to Lake Julian
Once - Through Cooling Water
This flow provides condenser cooling water for the generating units 1 and 2. Maximum
condenser flows for units 1 and 2 are 150 MGD and 156 MGD, respectively.
Once - through cooling water is used to supply non - contact cooling water for the component
closed cooling water system. The component closed cooling water system flows combine with
unit 1 and 2 condenser flows prior to discharge to Lake Julian. Maximum component closed
cooling water system flows for unit 1 and 2 are 9.1 MGD and 10.2 MGD, respectively.
Discharge flow to Lake Julian is calculated at the intake to units 1 and 2 condensers and to the
circulating water to the heat exchanger. The discharge of water from the heat exchangers is
routed to an ash sump. The majority of this water is further routed to the discharge of units 1
and 2 condensers. Less than one percent of the flow to the ash sump is used to supply ash
sluice water, preheater cleaning water, and fire protection water.
Control of biological fouling on heat - exchanger surfaces is accomplished by addition of sodium
hypochlorite as required, which is usually less than 2 hours per day per unit, with a net total
residual chlorine of less than 0.2 ppm discharged during that period. Cooling is accomplished
by evaporation from the surface of Lake Julian and mixing and convection with lake waters.
Make up for Lake Julian is from the French Broad River, natural runoff and creek flows. Water
is pumped from the French Broad River during dry periods to supplement the flow. Although
discharge from Lake Julian to the river is extremely rare, any occurrence would be during
periods of heavy rainfall.
Herbicide and Pesticide Usage in the Treatment System Ponds
Herbicides may be used as needed to control nuisance aquatic vegetation. These herbicides
are applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator. Pesticides may be used as needed including the performance of biological
assessments. The pesticides will be applied in accordance with the Pesticide General Permit
NCG560000, where applicable, and the manufacturer's instructions.

EXECUTIVE SUMMARY
The following report summarizes an evaluation of the Asheville Steam Electric Plant
1964 and 1982 ash pond dam engineered drains and seepage flow downgradient of the
ash ponds toward the French Broad River. 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 June 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 NC0000396. The purpose of the evaluation was to determine additional
potential outfalls for inclusion within the permit.
' Seventeen representative seep locations, the 1964 and 1982 ash pond dam engineered
drains and two surface water locations on the French Broad River were sampled for
' water quality analysis on June 25 and 26, 2014. Interstate 26 is located between the
Asheville Steam Electric Plant and the French Broad River. Ten of the sample locations
were located in the floodplain of the French Broad River on the west side of Interstate
' 26. The samples from the French Broad River were collected upstream of the Asheville
Plant property (FB -01) and downstream of potential seep influence (FB -02).
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 the French Broad 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 French Broad River and demonstrate reasonable potential
to exceed a water quality standard, Duke Energy will do one of the following: (1) stop
' the seep; (2) capture and route the seep so it is discharged through a NPDES permitted
outfall; or (3) address the seep using Best Management Plans approved by DWR.

' 1.0 INTRODUCTION
' Duke Energy Progress, Inc. (Duke Energy) owns and operates the Asheville Steam
Electric Plant (Asheville Plant) located on approximately 786 acres in Arden, Buncombe
County, North Carolina. The majority of the Asheville Plant operations are situated
' between Lake Julian to the east and I -26 to the west. The western property line follows
the French Broad River. The topography of the plant property is shown on Figure 1.
' The Asheville Plant began operations in 1964. Lake Julian was created by damming
Powell Creek to provide cooling water for the plant. Lake Julian is supplemented with
water pumped up from the French Broad River. Coal combustion residuals (CCRs)
were originally sluiced to an ash pond situated in the northwest area of the plant proper
(on the east side of I -26). The original ash pond is generally referred to as the '1964 ash
pond'. In approximately 1982, a second ash pond was constructed adjacent to the south
side of the 1964 ash pond. The second ash and is generally referred to as the '1982 ash
P P g Y
pond'. Currently, lined wastewater treatment units are located on the 1964 pond. The
' 1982 pond is currently being dewatered and the ash is being removed for beneficial fill
at the Asheville Regional Airport.
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 NC0000396.
The following report summarizes an evaluation of the engineered drains associated
with the 1964 and 1982 ash pond dams and seepage flow downgradient of the ash
ponds toward the French Broad River. 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 June 2014.

' 2.0 SEEP MONITORING
' 2.1 Seep Identification
A detailed reconnaissance of the 1964 and 1982 ash pond dams and the areas
downslope to the French Broad River was conducted during the spring of 2014 to
' determine locations of possible seeps. Representative seep locations were further
evaluated in June 2014 with the collection of flow rates, water quality data, photographs
and GPS survey information. Table 1 lists the representative seep locations and
' engineered drains associated with the two dams. The summary table includes the
latitude and longitude of each location, a general description of its physical location,
' and general flow observations. The locations of the representative seeps evaluated in
June 2014 are shown on Figure 2.
Seepage flow is generally variable. Flow may increase or decrease depending on the
amount of rainfall, groundwater levels, weather conditions, and other factors.
' 2.2 Seep Flow Measurement
Flow measurements were collected on June 25 and 26, 2014 at the seep and engineered
drain locations using either a Son -Tek FlowTracker ® Acoustic Doppler Velocimeter or
' the timed - volumetric method. The FlowTracker® measures stream velocity and
discharge using sound waves. The timed - volumetric method was used for locations
' where the channel configuration or the seep flow rate was not conducive for the
FlowTracker® to record a signal. The engineered drains are designed to allow for
collection of flow rates using the timed- volumetric method.
' The timed - volumetric method included the collection of a measured volume of water
from the seep or engineered drain directly into an appropriately sized container
' (graduated cylinder or bucket). The seep flow was routed to a container. The amount
of time (in seconds) required to collect a known volume of water was recorded.
Approximately three to five timed volumes were recorded for a seep location. The
' average flow rate for the seep was calculated based on an average of the timed volume
measurements.
' The Flowtracker® was used to measure seep flows where the volume of flow and the
depth of the flow channel were adequate. The method is designed for wadeable
' streams. Use of the FlowTracker® was generally limited to channels of sufficient width
(approximately 0.5 ft. or greater) and depth (approximately 0.17 ft. or greater). Flow
measurements (water velocity and depth) within the instrument's internal quality
' assurance and quality control bounds were recorded. Locations were selected where
channel banks were fairly parallel. The channel width was measured at the water line.

Seep Monitoring Report July 2014
Asheville Steam Electric Plant, NPDES Permit # NC0000396 SynTerra
' 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.
' 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. The flow velocity measurements were
collected at approximately 60% of water depth as appropriate due to water depths
IN being less than 2.5 feet.
Engineered drains at the base of the 1964 ash pond, 64EO -1 and 64EO -2, collect water
into two PVC pipes where flow rates can be collected used a bucket and stop watch
(timed - volumetric method). A section of the 1964 dam seeps into a swale along the
dam access road. The point where the seep is consolidated to flow under the road is
referred to as 64EO -3. The flow rate at this location was measured using a peristaltic
pump to collect the seep into a graduated cylinder (timed - volumetric method).
The engineered drains at the base of the 1982 ash pond are collected in a weir box.
Plant personnel routinely measure the flow rates from the water height on the weirs.
The June 2014 flow rates were collected using the timed - volumetric method.
Seep and engineered drain flow rates recorded during June 2014 are summarized in
Table 2.
2.3 Seep Sample Collection
Seventeen representative seep locations, the 1964 and 1982 engineered drains and two
surface water locations on the French Broad River were sampled for water quality
analysis on June 25 and 26, 2014. Interstate 26 is located between the Asheville Steam
Electric Plant and the French Broad River. Ten of the sample locations were located in
the floodplain of the French Broad River on the west side of Interstate 26. The influence
of I -26 on the seep flows and characteristics is unknown. The samples from the French
Broad River were collected upstream of the Asheville Plant property (FB -01) and
downstream of potential seep influence (1713-02). The June 2014 sample locations are
described in Table 1 and are shown on Figure 2.
Water quality samples were collected from the seep locations directly into sample
' containers. Care was taken to avoid disturbing and entraining particulate, soil or
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.
The French Broad River samples were collected midstream as grab samples from a
depth of approximately 1 meter.
Laboratory analyses were conducted by Duke Energy's Huntersville analytical
laboratory (NC Wastewater Certification #248) and Pace Analytical Laboratories (NC
Wastewater Certification # 12). A summary of the analytical results and flow rates are
presented in Table 2. A listing of analytical parameters and associated methods for the
June sampling event are included in Table 3. Sample handling, storage, and
preservation methods are summarized in Appendix A.

2Except where noted in this Table II and the method for the parameter, preserve each grab sample within 15 minutes of collection. For a
composite sample collected with an automated sample (e.g., using a 24 -hour composite sample; see 40 CFR 122.21(g)(7)(i) or 40 CFR Part
' 403, Appendix E), refrigerate the sample at 56 °C during collection unless specified otherwise in this Table II or in the method(s). For a
composite sample to be split into separate aliquots for preservation and /or analysis, maintain the sample at :56 °C, unless specified otherwise
in this Table II or in the method(s), until collection, splitting, and preservation is completed. Add the preservative to the sample container prior
to sample collection when the preservative will not compromise the integrity of a grab sample, a composite sample, or aliquot split from a

composite sample within 15 minutes of collection. If a composite measurement is required but a composite sample would compromise sample
integrity, individual grab samples must be collected at prescribed time intervals (e.g., 4 samples over the course of a day, at 6 -hour intervals).
Grab samples must be analyzed separately and the concentrations averaged. Alternatively, grab samples may be collected in the field and
composited in the laboratory if the compositing procedure produces results equivalent to results produced by arithmetic averaging of results of
analysis of individual grab samples. For examples of laboratory 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).
'When any sample is to be shipped by common carrier or sent via the U.S. Postal Service, it must comply with the Department of
Transportation Hazardous Materials Regulations (49 CFR part 172). The person offering such material for transportation is responsible for
ensuring such compliance. For the preservation requirement of Table II, the Office of Hazardous Materials, Materials Transportation Bureau,
Department of Transportation has determined that the Hazardous Materials Regulations do not apply to the following materials: Hydrochloric
acid (HCl) 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 0-0 °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.
'For dissolved metals, filter grab samples within 15 minutes of collection and before adding preservatives. For a composite sample
collected with an automated sampler (e.g., using a 24 -hour composite sampler; see 40 CFR 122.21(g)(7)(i) or 40 CFR 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.
"Guidance 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.
70The pH adjustment is not required if acrolein will not be measured. Samples for acrolein receiving no pH adjustment must be analyzed
within 3 days of sampling.
"When the extractable analytes of concern fall within a single chemical category, the specified preservative and maximum holding
times should be observed for optimum safeguard of sample integrity (i.e., use all 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 56 °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).
t21f 1,2- diphenylhydrazine is likely to be present, adjust the pH of the sample to 4.0 ±0.2 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
t6Place 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.
"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.
"Aqueous samples must be preserved at 56 °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 "5 °C" is used in place of the 'A °C" and " <4 °C" sample temperature requirements listed in some methods. It is
not necessary to measure the sample temperature to three significant figures (11100th 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).
9An 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
immediatelI (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.
2OTo 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.
27Holding 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.
' "Sample analysis should begin as soon as possible after receipt; sample incubation must be started no later than 8 hours from time of
collection.
23For 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).

1.0 INTRODUCTION
Duke Energy Progress, Inc. (Duke Energy) owns and operates the Asheville Steam
Electric Plant (Ashville Plant) site. The Asheville Plant is located south of Interstate I -26
exit number 37 at 200 CP &L Drive, Arden, North Carolina. The property encompasses
approximately 786 acres (Golder, 2007) on both sides of I -26, with the majority of the
plant operations located to the east of I -26. The property includes Lake Julian, located
to the east of the plant operations area. The property borders the French Broad River to
tthe west as shown on Figure 1.
The Asheville Plant began commercial operation in 1964, with additions in 1971, 1999
' and 2000, and consists of two coal -fired units that primarily use bituminous coal to
produce 376 - megawatts of power. The Plant also has two combustion turbines capable
' of producing 324 megawatts. Ash generated from the coal combustion has been stored
on -site in ash management area and is also used as beneficial fill at the nearby Asheville
Airport. The on -site ash management area is shown on Figure 1.
' The discharge from the ash management area is permitted by the North Carolina
Department of Environment and Natural Resources (NCDENR) Division of Water
' Resources (DWR) under the National Pollution Discharge Elimination System (NPDES)
Permit NC0000396.
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 Asheville Plant ash management area compliance boundary (Figure
1). 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.
IThe survey scope and findings are presented in the following sections.

2.0 BACKGROUND
2.1 Plant and Ash Management Area Description
The Asheville Plant began commercial operation in 1964, with additions in 1971, 1999
and 2000 and consists of two 376 - megawatt coal -fired units that primarily use
bituminous coal as fuel to produce steam. The site also includes two combustion
turbines capable of producing 324 megawatts. Ash generated from the coal combustion
has been stored on -site in ash management area and is also used as beneficial fill at the
nearby Asheville Airport. The on -site ash management area is shown on Figure 1.
Air emissions reduction scrubbers were installed in 2005. A physical and chemical
wastewater treatment system was built to remove metals from the scrubber water. The
Asheville Plant has a permitted wastewater National Pollutant Discharge Elimination
System (NPDES) outfall (001) to the French Broad River. The discharge from the
scrubber wastewater treatment system flows through a series of engineered wetlands
for additional treatment (metals precipitation) prior to discharge through an internal
NPDES outfall 005. The engineered treatment wetlands were constructed over the first
ash pond built in 1964. The treatment wetlands basins are lined.
A second ash pond, built in approximately 1982, is being dewatered and excavated.
' The ash is being transported to the Asheville Airport and used as structural fill. New
ash being generated daily is currently treated in concrete lined basins that lie on top of
the 1964 ash pond. Dewatered ash is also transported to the Asheville Airport for use
as structural fill. The treatment wetlands, stormwater, and treated sluice water are
collectively discharged through the NPDES 001 outfall to the French Broad River.
Lake Julian was built for cooling water by damming the flow of Powell Creek and its
tributaries on the north side of the plant site prior to its discharge to the French Broad
River. Lake Julian and the flooded portion of Powell Creek border the east side of the
plant site. Powell Creek flows south to north. Surface water from the French Broad
River is also pumped into Lake Julian as a supplemental water supply. The water from
the French Broad River enters a stilling area of the lake on the north side of the plant.
Heated water is discharged back into Lake Julian to the east of the plant NPDES outfall
002.
2.2 Description of Surrounding Properties
Properties located within a 0.5 mile radius of the Asheville Plant compliance boundary
are located in Buncombe County, North Carolina. The properties' uses include
residential, commercial, industrial and agricultural. The French Broad River flows
south to north along the western side of the property.
Figure 1 depicts the properties surrounding the Asheville Plant.

3.0 RECEPTOR SURVEY ACTIVITIES
3.1 NCDENR Records Review
SynTerra reviewed the NCDENR Department of Environmental Health (DEH) Public
Water Supply Section's (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 -.H 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 Asheville 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 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 any wellhead protection areas located within a 0.5 mile
' radius of the compliance boundary. The NCDENR SWAP database provides detailed
assessments of all public drinking water intakes and wellhead protection areas in North
Carolina. The website address is: ( http: / /swap.ncwater.org /website /swap /viewer.htm).
3.2 Environmental Data Resources, Inc. Records Review
A review of public database information provided by Environmental Data Resources,
' Inc. (EDR) was also conducted. The public water well information has been
incorporated in the summary table (Table 1) and on Figure 1. A copy of the EDR report
is included as Appendix A.
' 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. Hydrography data obtained from the USGS NHD
is included on Figure 1.

' 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
The EDR report identified one water supply well potentially located near the survey
area. A well is reported at the Poplar Terrace Mobile Home Park located on Bradley
' Branch Road (Figure 1). Buncombe County GIS data confirms the Poplar Terrace
Mobile Home Park at this location (185 Bradley Branch Road).
' No well construction information is provided. The EDR Report lists a number of
violations for failure to report for this well. A copy of the EDR Report is provided in
' Appendix A. Visual reconnaissance did not identify the location of this well.
4.3 USGS Hydrography Review
An approximate 9,000 foot long section of the French Broad River is located within the
western portion of the survey radius (Figure 1). The French Broad River flows north.
' Several small surface water features, including Powell Creek to the north and an
unnamed tributary to the south, and the French Broad River are present within the 0.5
mile radius of the compliance boundary. Powell Creek to the north, and the unnamed
tributary to the south and the French Broad River are hydrogeologic boundaries around
the Plant. The surface water features on both sides of the French Broad River flow
toward the river.
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
' on Figure 1 as reported /observed water supply wells (DW). Most of the area
development consists of residential and commercial properties with some industrial
and agricultural uses. Structures resembling wells or well houses were observed on
' Hoyt Road and Bear Leah Trail. Additional properties within the 0.5 mile radius of the

compliance boundary appeared to be developed and in -use (occupied) with no
apparent municipal water supply. These properties are noted on Figure 1 as possible
' water supply well (PRW).
4.5 Previous Water Well Survey Information
' The S &ME survey reported five active water supply wells located within 0.5 mile radius
of the compliance boundary.
' • Two supply wells located at 38 and 40 Bear Leah Trail.
• One well on Glenview Road.
• One well on Glenn Bridge Road.
• One well on Long Shoals Road.
' Based on the S &ME findings, NCDENR sampled the five wells during 2013.
4.6 Summary of Receptor Survey Findings
' A summary of the receptor survey findings are discussed below. The possible reported
and observed water supply well locations are shown on Figure 1. The locations are
numbered on the map to cross - reference information provided in Table 1. The table
summarizes property location and owner information.
' • No wellhead protection areas were identified within a 0.5 mile radius of the
compliance boundary.
' • Approximately 18 possible private water supply wells were observed, have been
reported, or may be located within 0.5 mile of the compliance boundary.
• All the water supply wells identified are located hydraulically upgradient,
sidegradient or are separated from the plant watershed by a significant hydraulic
divide (the French Broad River).
• One community supply well is reported for the Poplar Terrace Mobile Home
Park located on Bradley Branch Road. However, records are not current, the
well was not observed and a water line is available.
• 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 French Broad
' River.

EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in
forming an opinion about the impact of potential contaminant migration.
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.
TC3997186.1s Page 1

GEOCHECK®R - 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.

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.

' 2.0 SITE DESCRIPTION
' 2.1 Plant and Ash Management Area
The Asheville Plant began commercial operation in 1964, with additions in 1971, 1999
and 2000, and consists of two coal -fired units that primarily use bituminous coal to
' produce 376 - megawatts of power. The Plant also has two combustion turbines capable
of producing 324 megawatts. Ash generated from the coal combustion has been stored
on -site in the ash management area and is also used as beneficial fill at the nearby
' Asheville Airport. The on -site ash management area is encircled within the waste
boundary and 500 -foot compliance boundary shown on Figure 1.
Lake Julian was built for cooling water by damming the flow of Powell Creek on the
north side of the plant. A large portion of Lake Julian borders the east side of the plant
site. Powell Creek flows south to north. Surface water from the French Broad River is
also pumped into Lake Julian as a supplemental water supply. The water from the
French Broad River enters a stilling area of the lake on the north side of the plant.
Heated water is discharged back into Lake Julian to the east of the plant. The French
Broad River borders the west side of the property and flows south to north.
2.2 Ash Management Area Description
The power plant and ash management area are located on the east side of I -26 and the
French Broad River. The current configuration of the ash management area is shown on
Figure 2. The ash management area consists of:
• The original 1964 ash pond, built during plant construction and expanded in the
1970s, is now overlain with wastewater treatment wetlands. The treatment
wetlands basins are lined.
• The 1964 ash pond was replaced with a second ash pond, built in approximately
1982, located to the south of the 1964 ash pond.
The 1982 ash pond is being dewatered and excavated. The ash is being
transported to the Asheville Airport for structural fill. New ash is being
generated daily and is being dewatered in concrete lined basins located on top of
a portion of the 1964 ash pond.
The ash pond system is an integral part of the plant's wastewater treatment system
which receives inflows from ash transport water, coal pile runoff, storm water runoff,
and various low volume wastes. The treated wastewater from the ash management
area is permitted to discharge to the French Broad River via permitted Outfall 001. The
500 foot compliance boundary circles the ash management area (Figure 2).

3.1 Geologic /Soil Framework
The Asheville Plant is located in the Piedmont Mountain region of North Carolina as
described by LeGrand (2004). In general, the regional geology consists of overburden,
also referred to as regolith, and metamorphic bedrock. In stream valleys, fluvial
deposits, also referred to as alluvium, overlie the bedrock. The metamorphic rock,
primarily schist and gneiss, tends to be exposed on the ground surface along
topographic ridges, road cuts, and in stream or river valleys. Where the metamorphic
bedrock has been weathered into unconsolidated material, silt, sand and clay are found
overlying the bedrock. The two layers, regolith /saprolite or alluvium, and consolidated
bedrock form the basic framework of the groundwater system. The transition zone
between the regolith and consolidated bedrock can be a significant hydrogeologic
feature in the system.
The regolith tends to be composed of a shallow soil zone where the relict structure of
the original bedrock material is no longer present. The soil zone transitions downward
into saprolite, which is still unconsolidated material, but has the visual texture of the
parent bedrock. Saprolite is generally composed of silt, sand, and clay with a porosity
ranging from 35 to 55 percent, making it a storage reservoir for groundwater with good
natural attenuation characteristics. Where the thickness of saprolite is thin, or it is not
present, the saturated zone may be entirely in fractured bedrock. The consolidated
nature of the bedrock limits the presence and transport of groundwater to fractures
interconnected with the ground surface or the overlying regolith. In areas where the
saprolite to competent bedrock is gradual, the slightly weathered rock referred to as the
'transition zone' can be a significant zone of groundwater transport.
The differences in the geologic settings, and natural variations in mineralogy, of the
monitoring well screened intervals will result in natural variations in groundwater
chemistry. The geology across the site varies from mica gneiss and garnet mica schist in
the upland areas (east of I -26) to alluvium along the French Broad River floodplain
(west of I -26).
The mica gneiss (mgn) that underlies the majority of the site under the ash management
area is described at a number of locations as containing pyrite, chlorite and garnets (see
boring logs for PZ -113, PZ -17D). Mica schist is located in the vicinity of the compliance
boundaries to the south and north of the site. Background well CB -1 and compliance
boundary wells GW -1, CB -2, CB- 3 /CB -3R, CB-4 and CB-4B are located within the garnet
mica schist (gms) along the south side of the site. Compliance boundary wells CB -5,

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit A NC0000396 SynTerra
CB -6, and CB -7 are located within the alluvium (Qal) that follows the flood plain of the
French Broad River. Compliance boundary well CB -8 is screened in the mica gneiss
bedrock. The saprolite at this location is dry. CB -9 was installed in the mapped area as
mica gneiss; however, the cuttings during well installation appeared to represent mica
schist.
Compliance boundary background wells CB -1 and CB -9 are representative of upland
geology on the south and north sides of the property, with CB -1 being screened in
saprolite and CB -9 being screened in weathered bedrock. CB -5 is representative of the
alluvial aquifer conditions.
3.2 Hydrogeologic Framework
The geology at the depth of the water table (the screened interval for most of the site
compliance boundary wells) varies across the site from being within the regolith (within
the saprolite), the transition zone between saprolite and competent bedrock, within the
upper bedrock, or within floodplain alluvial deposits.
Regolith is known for having a high capacity for groundwater storage, but the silts and
clays transmit water very slowly. Fractured bedrock has low storage capacity but can
transmit water very quickly. In some areas, a zone of partially weathered rock may
occur beneath the saprolite and over competent bedrock. The zone of partially
weathered rock is also referred to as the 'transition zone'. The transition zone tends to
be sandy with coarse grained weathered rock fragments creating a significant
groundwater transport zone where present.
The topography of the water table (the depth to the saturated aquifer) tends to mirror
the ground surface topography. Topographic ridges and stream valleys, or topographic
lows between ridges create groundwater divides. The groundwater flow will follow the
surface topography until the water table intersects the ground surface in a spring, seep
or stream.
As discussed by LeGrand (2004), the French Broad River and its tributaries are
groundwater discharge zones for the saprolite and bedrock aquifer at the site. The
French Broad River creates a hydrogeologic boundary to the west of the plant site. The
Powell Creek drainage feature creates a hydrogeologic boundary to the north side of the
site. The unnamed tributary located along the southern property line creates a
hydrogeologic boundary to the south of the site. Lake Julian is located upgradient of
the ash management area and it, along with the Powell Creek drainage basin, form the
eastern hydraulic boundary of the site.

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit # NC0000396 SynTerra
As further discussed by LeGrand (2004), groundwater moves continuously toward
streams where it discharges in small springs or seeps in draws or topographic
depressions. The path of groundwater is restricted by topography. Groundwater rarely
passes beneath a perennial stream to another groundwater flow system. Thus the
concept of local slope aquifer systems, or compartments, applies to the regional
geologic setting of the site. The high crests of the water table (recharge zones) represent
natural groundwater divides as do the low lying stream discharge zones. These
localized hydrogeologic flow system compartments tend to keep potential contaminant
migration within the flow compartment from which it originates. It is possible,
although unusual, that isolated bedrock fractures that receive recharge from one slope
aquifer compartment could extend beneath a boundary stream and intercept a fracture
serving a well in a neighboring slope aquifer compartment. This can occur when a
pumping well pulls the groundwater beyond its natural discharge zone.
Most of the compliance boundary wells are screened near the depth of the water table
within the saprolite or the transition zone with the exceptions being CB -413, CB -8 and
CB -9. CB-4B is screened in the first water - bearing zone within the upper bedrock for
the purpose of determining the vertical hydraulic gradient at this location.
There is a downward vertical head of approximately six feet from the lower saprolite
(CB -4) to the upper weathered bedrock (CB -4B) at this location. At CB -8, the first
occurrence of water is in fractured bedrock. Therefore, background well CB -9 was
installed in bedrock also to account for the natural variability in bedrock conditions on
the north side of the site.
The general direction of groundwater flow in the saprolite aquifer is west, toward the
French Broad River, with localized variations as the water table mirrors surface
topography. The saturated saprolite aquifer feeds the underlying fractures within the
upper bedrock aquifer as evidenced by the downward vertical gradient observed in
upland well cluster CB -4/4B. The direction of groundwater flow in the upper bedrock
aquifer is also generally to the west, toward the French Broad River, with preferential
flow paths toward the small tributaries and exposed outcrops along I -26 (localized
discharge zones).
The average precipitation in the Asheville, NC area is approximately 48 inches per year.
Due to site topography and lower transmissivity rates for the saprolite aquifer, recharge
rates are estimated to be moderate to low.
There are no water supply wells located near the compliance boundary that would
likely affect the natural groundwater flow pattern at the site.

4.0 MONITORING PROGRAM
' 4.1 Regulatory Requirements for Groundwater Monitoring
The NPDES program regulates wastewater discharges to surface waters to ensure that
surface water quality standards are maintained. Asheville operates under NPDES
' Permit NC0000396 (effective November 24, 2009) which authorizes discharge as follows.
• Ash Pond Treatment System ( Outfall 001). Outfall 001 discharges directly to the
' French Broad River. The ash pond receives ash transport water, coal pile runoff,
storm water runoff, various low volume wastes (such as boiler blowdown,
backwash from the water treatment processes, ash hopper seal water, plant
' drains), air preheater cleaning water and chemical metal cleaning wastewater
discharged from Internal Outfall 004 (potentially).
f• Once Through Non - Contact Cooling Water System Outfall 002). This
wastestream is discharged directly to Lake Julian via Outfall 002.
' • Chemical Metal Cleaning Treatment System ,Internal Outfall 0041. This
wastestream may occasionally be discharged via Internal Outfall 004 to the ash
' pond treatment system or to the old ash pond (with prior DWR approval).
Generally chemical metal cleaning wastes are treated by evaporation in boilers.
' • Flue Gas Desulfurization (FGD)(Intemal Outfall 005). This wastestream consists
of the wet scrubber wastewater treatment system, which will discharge to the
secondary settling basin (after the Ash Pond) via internal Outfall 005 (with
' ultimate discharge via Outfall 001).
In addition to surface water monitoring, the NPDES permit requires groundwater
monitoring. Attachment XX, Version 1.0, dated November 12, 2010, 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. These requirements are provided in Table 2. Attachment XX also provides
requirements for well location and well construction. A copy of Attachment XX is
included as Appendix B.
The compliance boundary for groundwater quality associated with the Asheville 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.

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit A NC0000396 SynTerra
In accordance with the November 12, 2010 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 compliance monitoring program for the Asheville Plant
includes the sampling of 11 wells. Since November 12, 2010, (the most recent written
monitoring plan), one of the listed wells (CB -3) was replaced with CB -3R and an
additional background well (CB -9) was added to the routine sampling.
The 11 wells comprising the current monitoring well network at Asheville include two
(2) background wells and nine (9) 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 at the site, the general direction of groundwater flow is
west, toward the French Broad River. The site wells provide monitoring data for the
groundwater at the compliance boundary downgradient of the ash management area.
The compliance monitoring network includes two background monitoring wells, CB -1
and CB -9, plus nine monitoring wells located in side - gradient and downgradient
positions along the compliance boundary. The downgradient compliance boundary
wells were installed in the water table with the exception of CB -4B which was installed
in the upper bedrock approximately 20 feet deeper than lower saprolite compliance
boundary well CB-4 to monitor the vertical hydraulic gradient in the area. For CB -8, the
first occurrence of groundwater was located in competent bedrock. The remainder of
the downgradient compliance boundary wells were installed in the saprolite or
alluvium, above bedrock. Background well CB -9 was installed to monitor background
bedrock aquifer conditions on the north side of the Plant in a similar geologic setting as
CB -8.
In December 2010, Progress Energy Carolinas (PEC), now Duke Energy Progress, Inc.,
purchased additional property to the south of the plant, revising the compliance
boundary near CB -3. As a result, CB -3 was replaced by CB -3R at the new compliance
boundary. CB -3R was screened at the top of competent bedrock within the transition
zone as specifically requested by NCDENR (August 22, 2012 correspondence).

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit # NC0000396 SynTerra
The groundwater monitoring for most of the compliance wells began in November
2010. Monitoring of CB -3R and CB -9 began in November 2012. Well construction logs
are included in Appendix A.
4.3 Monitoring Frequency
The monitoring wells will be sampled three times per year in April, July, and
November.
4.4 Sample Parameters and Methods
The monitoring program consists of sampling and analysis for parameters and
constituents identified in Attachment XX of the NPDES permit (Appendix B).
The parameters and the analytical methods are presented in Table 2.
The analytical results for the monitoring program will be compared to the 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
analytical problems with the data, if needed.

5.0 SAMPLING PROCEDURES
5.1 Sampling Equipment and Cleaning Procedures
Development and sampling equipment shall be selected to ensure that materials are
compatible with the sample parameters and comply with state and federal regulatory
requirements for sampling.
New disposable sampling equipment (peristaltic pump tubing) is used for each
monitoring well sampled. For non - dedicated equipment used, such as water level tapes
and submersible pumps, the equipment will be cleaned before and after use in each
well in accordance with standard EPA - approved cleaning procedures for field
equipment. This standard is outlined in the Standard Operating Procedures and
Quality Assurance Manual, Engineering Support Branch, EPA Region IV, February 1,
1991 as revised December 20, 2011.
5.2 Groundwater Sampling
5.2.1 Development of Monitoring Wells
Monitoring wells addressed in this sampling plan have been developed.
If new monitoring wells are installed, they will be developed prior to initial
sampling. Development removes silt that has settled into the bottom of the well
following installation and removes fine silt and clay particles from the well
screen and sand -pack surrounding the screen. Well development is necessary to
eliminate potential clogging and enhance well performance. Development
involves removing an estimated ten or more well volumes from the well using a
submersible pump with up- and -down agitation to loosen particles from the well
screen. If the turbidity for a well increases over time, the well may be re-
developed to restore conditions.
5.2.2 Groundwater Level and Total Depth Measurements
Water level measurements are collected and recorded to determine the
groundwater elevation and flow direction. Site monitoring wells have been
surveyed to determine the elevation of the top of well casing (TOC). Water level
measurements are referenced to the TOC and recorded to the nearest one-
hundredth of a foot.
Water level measurements are made with an electronic measuring device
consisting of a spool of dual- conductor wire and sensor. When the sensor comes
in contact with water, the circuit is closed and a meter light and /or buzzer

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit # NC0000396 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 Asheville Plant, a low -flow purging technique has
been selected as the most appropriate technique to minimize sample turbidity as
desired.
■ During low -flow purging and sampling, groundwater is pumped at flow rates
that minimize or stabilize water level drawdown within the wells. At Asheville,
' low -flow sampling is conducted using a peristaltic pump or low -flow
submersible pump with new tubing. The intake 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 a 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 mid -day, 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

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).

5.8 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

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.

6.0 ANALYTICAL PROCEDURES
The main analytical laboratory used in this program is the Duke Energy Analytical Lab
Services laboratory: 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

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.

Groundwater Monitoring Program July 2014
Asheville Steam Electric Plant, NPDES Permit # NC0000396 SynTerra
• Field Replicates: A field replicate is a duplicate sample prepared at the sampling '
locations from equal portions of all sample aliquots combined to make the
sample. Both the field replicate and the sample are collected at the same time, in ,
the same container type, preserved in the same way, and analyzed by the same
laboratory as a measure of sampling and analytical precision.

made of such materials that the monument will not be destroyed due to
activities taking place on the property. The map and any supporting
documentation shall be sent to the Division of Water Quality, Aquifer Protection
Section, 1636 Mail Service Center, Raleigh, NC 27699 -1636.
e. The well(s) must be constructed by a North Carolina Certified Well Contractor,
the property owner, or the property lessee according to General Statutes 87-
98.4. If the construction is not performed by a certified well contractor, the
property owner or lessee, provided they are a natural person, must physically
perform the actual well construction activities.
f. The monitoring wells shall be regularly maintained. Such maintenance shall
include ensuring that the well caps are rust -free and locked at all times, the
outer casing is upright and undamaged, and the well does not serve as a conduit
for contamination.

3. GROUNDWATER SAMPLING. Monitoring wells shall be sampled after construction and
thereafter at the frequencies and for the parameters as specified in the Attachment. All
mapping, well construction forms, well abandonment forms and monitoring data shall
refer to the permit number and the well nomenclature as provided on the Attachment.
a. Per 15A NCAC 02H .0800, a Division certified laboratory shall conduct all
laboratory analyses for the required effluent, groundwater or surface water
parameters.
b. The measurement of water levels shall be made prior to purging the wells. The
depth to water in each well shall be measured from the surveyed point on the
top of the casing. The measurement of pH shall be made after purging and prior
to sampling for the remaining parameters.
C. The measuring points (top of well casing) of all monitoring wells shall be
surveyed to provide the relative elevation of the measuring point for each
monitoring well. The measuring points (top of casing) of all monitoring wells
shall be surveyed relative to a common datum.
d. For initial sampling of monitoring wells, the Permittee shall submit a Compliance
Monitoring Form (GW -59) and a Well Construction Record Form (GW -1) listing
this permit number and the appropriate monitoring well identification number.
Initial Compliance Monitoring Forms (GW -59) without copies of the Well
Construction Record Forms (GW -1) are deemed incomplete, and may be
returned to the Permittee without being processed.
e. Two copies of the monitoring well sampling and analysis results shall be
submitted on a Compliance Monitoring Form (GW -59), along with attached
copies of laboratory analyses, on or before the last working day of the month
following the sampling month. The Compliance Monitoring Form (GW -59) shall
include this permit number, the appropriate well identification number, and one
GW -59a certification form shall be submitted with each set of sampling results.
All information shall be submitted to the following address:
Division of Water Quality
Information Processing Unit
1617 Mail Service Center
Raleigh, North Carolina 27699 -1617
4. COMPLIANCE BOUNDARY. The compliance boundary for the disposal system shall be
specified in accordance with 15A NCAC 02L .0107(a). This disposal system was
individually permitted prior to December 30, 1983; therefore, the compliance boundary
is established at either 500 feet from the effluent disposal area, or at the property
boundary, whichever is closest to the effluent disposal area. An exceedance of
groundwater standards at or beyond the compliance boundary is subject to remediation
action according to 15A NCAC 02L .0106(c) as well as enforcement actions in accordance
with North Carolina General Statute 143- 215.6A through 143- 215.6C.
