Subject: NPDES Permit NC0024406, Belews Creek Steam Station
Dear Mr. Dowden:
Enclosed with this letter is a complete application for renewal of NPDES permit NC0024406
authorizing discharges from the Belews Creek Steam Station. As a precursor to submission of
the application, Duke Energy Carolinas, LLC requests that the Division of Water Quality
exercise the Director's authority under 15A NCAC 02H.0106(b) to establish a new date for
submission of this permit application. Given the issues involved in the renewal of the Belews
Creek permit and a current expiration date of February 28, 2024, it may be challenging for the
Division to reissue this permit before the existing permit expires. Establishing a new application
deadline would allow for timely submission of the application and the continuation of existing
permit terms until the effective date of the new permit, in accordance with 15A NCAC
02H.0112(e).
A later submission date is justified in this situation by the potential impacts to the North and
South Carolina power grids from operational impacts to Belews Creek Station. To avoid
unlawful discharges, Duke Energy would potentially be required to curtail power production at
the station. With a capacity of greater than 2,200 MW, Belews Creek is Duke Energy's largest
non-nuclear dual fuel power plant and plays a significant role in providing electricity to the
residents of North Carolina and South Carolina. It functions as a Base Load resource, meaning
that it is relied on to run continuously in the summer and winter. It is especially important for
reliable operation of the power system for Belews Creek to be available at certain system
demand levels and system configurations. Belews Creek is located in an area of the system
where the VACAR-S Reliability Coordinator has identified an Interconnection Reliability
Operating Limit (IROL) that is heavily influenced by available generation and the load level in
the northern region of the Duke Energy Carolinas transmission system. (An IROL is defined as:
A System Operating Limit that, if violated, could lead to instability, uncontrolled separation, or
Cascading outages that adversely impact the reliability of the Bulk Electric System.) At certain
system demand levels and under certain system configurations, the loss of Belews Creek
generation and voltage support it provides can result in the need for firm load shed for retail and
wholesale customers to avoid the consequences of system contingencies that could lead to
cascading outages on the power system. Furthermore, extreme cold weather events and recent
outage events during Winter Storm Elliott in December of 2022 emphasized the need for
resource adequacy and reliability in North Carolina and across the region. The Belews Creek

generation has a significant role in meeting the resource adequacy and reliability in needs for
North Carolina and across the region. The importance of Belews Creek as a resource justifies a
new application deadline that will provide the Division with sufficient time to prepare the
renewed permit and avoid interruptions in operation.
Thank you for your consideration. Please let me know if you need any additional information to
evaluate this request.
Sincerely,
Zachary Hall

Subject: NPDES Permit Renewal Request
Belews Creek Steam station
NC0024406
Stokes County
Dear Dr. Chernikov,
Duke Energy Carolinas, LLC (Duke Energy)hereby requests renewal of the subject NPDES
permit set to expire on February 28, 2024. As mandated by North Carolina Administrative Code
15A NCAC2H.0105(e),this permit application is being submitted at least 180 days prior to
expiration of the current permit. Duke Energy respectfully asks for the following clarifications
in addition to renewal of the permit:
1. Duke Energy requests clarification as to required instream sampling related to outfall
006. The current permit condition A.(22.),refers to instream sampling associated with
outfall 003. Ash basin discharges through outfall 003 were eliminated as part of the work
completed under Consent Order EMC SOC S18-009. Outfall 006 is located downstream
of the previous outfall 003 location. Duke Energy requests the condition in outfall A.(22.)
be updated to allow for downstream sampling at the Pine Hall Road bridge. Property
access limitations and safety concerns exist downstream of outfall 006 as Duke Energy's
property ends near the outfall 006 location. There are no major tributaries between outfall
006 and the downstream bridge making it a suitable and well mixed location to measure
downstream effects from the discharge. A map showing the requested sampling location
is included as Attachment 4 to this submittal.
2. Duke Energy requests a dewatering flow limit increase to 3.0 million gallons per day
monthly average to be consistent with other Duke Energy permits.
3. Duke Energy requests that instream monitoring frequency be modified to quarterly with
the elimination of temperature monitoring, as there has been a demonstrated lack of
impact to the receiving stream from the station's operations.
www.duke-energy.com

4. Duke Energy requests that toxicity testing for Outfall 006a(decanting/dewatering
system) be modified to quarterly as the station has demonstrated compliance with the
modified waste stream flows that lead to the previously increased testing frequency.
5. Duke Energy requests that fish tissue monitoring near Outfall 006 be modified to once
per permit term occurring between years 1 to 4 of the permit term.
6. Duke Energy requests removal of Condition A(13.) Special Condition for Ash Pond
Discharge, since all flows to the ash basin have been discontinued and ash is actively
being excavated. Sufficient volume exists in the ash basin,periodic certification is not
needed.
7. Duke Energy requests various clerical updates to the permit to include:
a. Removal of reference to Outfall 003 as all flows previously routed to Outfall 003
are now discharged via Outfall 006 to the Dan River, including Condition A(3).
Effluent Limitations and Monitoring Requirements (Outfall 003 —Normal
operations/decanting).
b. Remove language for internal Outfall 009 discharging to UT to Dan River.
Outfall 009 discharges to the Dan River via Outfall 006. Remove all references to
any wastewater discharge to the UT to Dan River.
c. Remove all nonstandard permit language in permit condition A.(4). concerning
85%of the allowable level of As, Se, Hg,Ni and Pb. Decanting of the ash basin is
complete with only a very small pool of water remaining.
d. Modify footnote in permit condition a.(4). concerning interstitial flows to include
"the facility shall treat the wastewater discharged from the ash pond/ponds using
physical-chemical treatment, if necessary,"to make this permit consistent with
other Duke Energy permits.
e. Remove permit condition A.(10). concerning Toe Drain Outfall 111. This outfall
was rerouted to comingle with the discharge of Outfall 006 on June 1, 2020.
f. Remove permit condition A.(5). concerning Outfall 003A. This outfall was
rerouted to comingle with the discharge of Outfall 006 on July 13,2019.
Please find enclosed one signed original and two copies of the NPDES renewal application,

Introduction
Belews Creek Steam Station (BCSS) located in Stokes County, North Carolina, is a two-unit coal-
fired electric generating plant with a capacity of 2,220 megawatts (MW). The station began
commercial operations in 1974 with Unit 1 (1,110 MW) followed by Unit 2 (1,110 MW) in 1975.
Cooling water for BCSS is provided by Belews Reservoir, a man-made reservoir formed when Duke
Energy built the facility.
Chemical constituents contained in the discharge from the permitted outfalls will, in part, be
representative of the naturally-occurring chemical quality and quantity of the intake water and will
also have chemical constituents of such quality associated with similar discharges for fossil generating
facilities of the size, type, and in this geographical location. Either all or part of the elements in the
Periodic Table, either singularly on in any combination, may from time to time be contained in the
discharge. Plant waste streams are directly or indirectly discharged to either Belews Reservoir
(Outfall 001) or Dan River via (Outfall 006). Each component of the discharges are described
below.
Outfall 001—Condenser Cooling Water System(CCWS)
Outfall 001 is the discharge from the Condenser Cooling Water System(CCWS)to Belews Reservoir.
Various wastewater streams combine in the CCWS prior to discharge. These flows consist of
Condenser Cooling Water (CCW), Intake Screen Backwash, Recirculated Cooling Water
(RCW), Hydrogen and Oil Coolers and Station equipment cooling water.
Condenser Cooling Water
Raw water from Belews Reservoir is passed through condensers and auxiliary equipment on a
"once-through" basis to cool equipment and condense exhaust steam from the turbines.
Cooling water passes through a network of tubes in the condenser and selected heat exchangers
(e.g. turbine lube oil coolers, condensate coolers, miscellaneous closed system coolers). Raw
water in the condenser tubes absorbs heat from a closed system of highly purified exhaust
steam from the turbines and converts it back to water.The condensed exhaust steam is returned
to the boilers and recycled in this loop a number of times. The raw cooling water is returned to
the reservoir. No chemicals are added and only heat rejected from the condensers and
auxiliary equipment is absorbed, hence the term "once through, non-contact cooling water" is
applied.
The condensers at BCSS are cleaned mechanically. Normally,amertap balls clean the tubes on
a continuous basis while the plant is operating. Periodically, metal scrapers,plastic scrapers or
rubber plugs are forced through the tubes to rid them of scale or other deposits.
Each unit at BCSS has four condenser cooling water (CCW) pumps. Normal plant operation
of the CCW pumps is based on intake and discharge temperatures and unit loads. To avoid a
system trip that would suddenly reduce the discharge flow at Outfall 001, each unit is on an
independent system. This practice leads to higher reliability factor for the units and protection
of aquatic life taking refuge in the discharge canal during cold weather.

September 2023
Page 2 of 9
Intake Screen Backwash
Each unit has four stationary intake screens (18 ft x 23 ft) which are removed for cleaning.
The intake screens are backwashed as needed at a rate of 500 gpm for approximately five
minutes each. The total volume of water used is 0.02 MGD. Intake screen backwash is
discharged back into the station intake. The debris removed is collected within a cleaning
basin and consists of twigs, leaves,and other material indigenous to Belews Reservoir.
Recirculated Cooling Water(RCW)System
The RCW system is a closed loop cooling water system. Depending on the temperature of the
raw reservoir water and the operation of BCSS, once through non-contact CCW is passed
through the RCW coolers to maintain the closed loop cooling water within the RCW system at
<95°F. RCW system supplies cooling water to various equipment and is composed of a storage
tank,three 50% capacity RCW pumps,two 100%capacity heat exchangers (RCW coolers), and
associated piping and valves for the two units. Recirculated cooling water is supplied from the
CCW system to the RCW storage tank(capacity of 19,000 gallons)and makeup water is added,
as required per tank level and temperature controls. The maximum flow of CCW through each
of the two RCW coolers is 5,360 gpm or 7.72 MGD. Non-contact cooling water discharged
from the RCW coolers combines with the condenser cooling water and is discharged through
Outfall 001.
RCW System contains maintenance chemicals in order toprevent corrosion. The primary
p ary
chemical used in the RCW system is sodium nitrite. Microbiocides are also used at very low
concentrations. The potential exists for the RCW system to have minor tube leaks, due to
material corrosion. Tube leaks from the RCW system discharge into the CCW system, which
discharges into Belews Reservoir through Outfall 001. Routine monitoring of the RCW system
for nitrite concentrations and the inventory of make-up water provides input that assists in
determining a tube leak. Once a leak is identified, corrective measures are implemented to
minimize and repair the leak. During routine maintenance the process water from the RCW
system drains to floor drains where it is pumped to the lined retention basin (Outfall 006).
During a leak and/or routine maintenance, the concentration of the maintenance chemical
will not exceed the No Observed Effect Concentrations(NOEC)at either Outfall 001 or 006.
Hydrogen and Oil Coolers
Once through non-contact cooling water is supplied from the Low Pressure Service Water
(LPSW) System that draws water from the CCW system to hydrogen and oil coolers. The
system consists of two High Pressure Generator Hydrogen Coolers (maximum combined flow
of 3,900 gpm), four Low Pressure Generator Hydrogen Coolers (maximum combined flow of
3,520 gpm), and two Turbine Lube Oil Coolers (maximum combined flow of 7,400 gpm) for
each unit. A maximum of 43 MGD of cooling water can flow through these coolers when
both BCSS units are operated at full load. Discharge from these coolers combines with the
condenser cooling water flow and discharges through Outfall 001.
Station Equipment Cooling Water
Once through non-contact cooling water is supplied from the Low and High Pressure Service
Water System to the bearings of the induced draft(ID)fans to remove excess heat. No

chemicals are added to the once through raw reservoir water discharged to Belews Reservoir.
The rate of flow through the control equipment is approximately 0.86 MGD when both BCSS
units are operated at full load. This effluent also includes chiller once through water.
Containment Flushin /Wash Waters
Infrequently, service water(raw water from Belews Reservoir)will be used to test the integrity
of onsite containment structures and for wash water in water trucks at the landfill site. There
are no chemicals added to the service water. The water is routed back to Belews Reservoir
through some stormwater drains.
Internal Outfall 002—Treated FGD Wet Scrubber Wastewater
The Wet Flue Gas Desulfurization (FGD) system was installed at Belews Creek in 2008 for the
reduction of Sulfur Dioxide (SO2) from the stack gas. The FGD system follows the electrostatic
precipitators (which removes fly ash) and also the Selective Catalytic Reduction (SCR) systems
(which uses anhydrous ammonia for nitrogen oxide (NOx) control). The use of this equipment
entails the use of or production of: calcium sulfite, vanadium pentoxide, calcium carbonate, and
sulfur.
After the electrostatic precipitator, the flue gas routed to the FGD system. Part of the coal
combustion process, sulfur dioxide produced. The FGD System removes SO2 by reacting the
flue gas with a limestone-water slurry. As the gas rises through the tank to the outlet at the top,
the gas passes through a spray header. An atomized slurry of water and limestone droplets is
continuously sprayed through this header into the stream of flue gas. The SO2 in the flue gas
reacts with the calcium in the limestone and produces calcium sulfite (CaSO3). This CaSO3 slurry
falls to the bottom of the tank where a stream of air is injected to oxidize the slurry to form
gypsum (CaSO4•H2O). The gypsum slurry is drawn off the absorber tank and pumped to a
hydrocyclones (primary and seconday) where solids are removed and part of the slurry is sent to a
vacuum belt filter for dewatering.
Part of the slurry is blown down primarily to keep the FGD chloride concentration below 12,000 ppm.
This waste is sent to a wastewater treatment system in order to remove solids, metals and reduce the
temperature. Initially, the wastewater is sent to an equalization tank to allow for a more constant flow
and solid loading to the next treatment steps. The wastewater from the equalization tank is pumped
through three reaction tanks where metal treatment and coagulation occurs. In the event of a
maintenance issue with the reaction tanks a bypass line is installed to route the flow around the
reaction tanks to continue treatment further downstream of the reaction tanks. Chemicals are still
added to the bypass line. After the treatment occurs in the reaction tanks, the wastewater is sent to
two clarifiers. Once the wastewater leaves the clarifiers, enters continuous backwash sand filters, then
the pH is readjusted and the wastewater is cooled by a heat exchanger. The treated wastewater is
then pumped to a two stage biological treatment system in order to reduce metal concentrations.
This treated wastewater is then discharged to the lined retention basin via Internal Outfall 002.
The following chemicals are utilized in the FGD wastewater treatment system: hydrated lime, ferric
chloride,polymer,hydrochloric acid,nutrients, citric acid,sodium hypochlorite,and hydrochlorite.

To comply with Federal Steam Electric Effluent Guidelines (ELG) for FGD wastewater, an
ultrafiltration system was added to the existing FGD wastewater system.
In compliance with Federal ELG guidelines for bottom ash system, there is an allowance to route
the bottom ash sluice water to FGD system. BCSS has route the bottom ash sluice water to the
FGD system. Bottom ash from the boilers is sluiced to submerged flight conveyors, dewatered,
and the ash solids landfilled. Ash sluicing water is recirculated in a closed loop system with make-up
provided from service water for evaporation and water loss through trucked transport ash moisture.
Outfall 006—Discharge of the Lined Retention Basin to the Dan River
The ash basin accommodates flows from the Power House sumps, Yard Holding sump, Consolidated
sump, Coal Yard Runoff basins and sumps, occasional minor hydrated lime and/or limestone
slurry system leakage, and rainfall run-off from the watershed of the basin. Flow from the engineered
toe drains and through the dam flow to the Dan River via Outfall 006.
The lined retention basin, accommodates flows from the Power House sumps, Yard Holding
sump, Consolidated sump, Coal Yard runoff basins and sumps, miscellaneous low volume
wastestreams, occasional minor hydrated lime and/or limestone slurry system leakage, and rainfall
run-off from the watershed of the basin.
Yard Holding Sump
Wastewater can accumulate in the yard holding sump from the power house sumps.
Power House Sumps
The Power House Sumps discharge to the yard holding sump and include wastewater from
water treatment equipment, floor wash water, equipment cooling water, low volume waste, and
miscellaneous leaks.
❖ Water Treatment System
The water treatment system consist of one retention tank, three pressure filter, two activated
carbon filters, one Reverse Osmosis (RO) system, and one set of makeup demineralizers. The
pressure filters each have a capacity of 250 gpm. The pressure filter media is composed of rock
and sand,therefore all backwash discharge to organic buildup from service water.
Makeup demineralizers are operated in sequence (one cell at a time). Regeneration of these
cells is required approximately every 40 days. Each regeneration requires 120 gallons of 66°Be
sulfuric acid and 600 gallons of 50%sodium hydroxide. As average dilute waste chemical and

rinse flow of 0.34 MGD is realized (for two hours per regeneration). The diluted acid and
caustic are discharged to the yard holding sump and then pumped to the ash basin/retention
basin. The useful life of the resin varies and when replacement is needed the spent resin is
sluiced to the basin.
The RO system is cleaned on an as needed basis using Osmonics AD-20 (275-lbs), Biomate
MBC 781 (2.5 gallons), sodium laurylsulfate(101bs)and sodium hydroxide(4L).
•S Condensate Feedwater System
The condensate feedwater system provides continuous flow-through boiler feedwater to BCSS
supercritical pressure boilers. Condensate polishing demineralizers of the powdered resin type
are used to filter feedwater. The mixed anion-cation powdered resin provides filtering and ion
exchange. Spent resins and associated wastes are pumped to the ash basin/retention basin for
treatment and disposal.
❖ Evaporative Losses,Soot Blowing
Exhaust steam from the turbine is used periodically to blow soot off the outside of the boiler
tubes. Thus, some of the condensate feedwater is evaporated in the boiler.
❖ Turbine and Boiler Room Drain System
Turbine and boiler room drains receive flow from once through non-contact cooling water of the
Station air conditioning system, fire protection system, washdown, and miscellaneous Station
uses.
❖ Station Air Conditioning
Once through non-contact cooling water is supplied from the Low Pressure Service Water
System to cool the Station air conditioning equipment. A maximum combined flow of 3.46
MGD of cooling water can flow through two chiller units. No chemicals are added to the once
through raw reservoir waste that drains to the Station sumps where it is pumped to the ash
basin/retention basin.
❖ Fire Protection, Washdown,and Miscellaneous Station Uses
The fire protection system, washdown, and miscellaneous station uses from closed system
drainage, cleaning, and testing can contain:
• Corrosion inhibitors,e.g. Calgon CS and Betz, Powerline 3201
• Biocides, e.g. Calgon H-300 and H-510
• Laboratory wastes
• Cleanings(e.g. small heat exchangers)Dispersant, e.g. polyacrylamide
• Wetting agent,e.g. disodium fluorescing dye
• Detergent,e.g.tri-sodium phosphate
• Leak testing,e.g. disodium fluorescing dye
• Miscellaneous system leakage's(small leaks from pump packing and seals, valve seals, pipe
connections)
• Moisture separators on air compressor precipitators
• Floor wash water

• Emergency firefighting water
• Ash sluice system overflow
• Low volume Wastewater
+ Groundwater(GW)Remediation
A GW remediation system was used to recover free petroleum product that leaked from a
underground storage tank. A total fluids recovery system was used to recover contaminated
groundwater and free product from the site. Remediation system equipment was used to
remove the petroleum from the recovered groundwater, and the reclaimed petroleum was
transported off-site for treatment while the treated wastewater was discharged to the ash
basin/retention basin via the Power House sump. A maximum flow rate of approximately 0.03
MGD was discharged to the ash basin/retention basin from the groundwater remediation system.
Remediation is complete and BCSS has closed out the system under UST Requirements.
❖ Fly and Bottom Ash Sluicing
Electrostatic precipitators are used to remove fly ash from the stack gases. The ash is treated in
the flue gas ductwork with SO3 conditioning to improve removal efficiency. Typically,the dry
flyash captured in these precipitators is collected in temporary storage silos for subsequent
disposal in a permitted on-site landfill or for recycling in off-site ash utilization projects. If the
system that collect the dry-fly ash. Bottom ash form the boilers is usually water sluiced to
the submerged flight conveyor system.
Electrostatic precipitators are normally cleaned by mechanically rapping the wires and plates
inside the precipitator. Before major precipitator work is performed they are cleaned by a wash
down. The wash water is pumped to the ash basin from the yard drain sumps.
Bottom ash from the boilers will be sluiced to submerged flight conveyors, dewatered, and
the ash solids will be landfilled. Ash sluicing water will be recirculated in a closed loop
system with make-up provided from service water for evaporation and water loss through
trucked transport ash moisture.
Coal Yard Runoff Basin and Sumps
The coal yard covers approximately 51.5 acres. The average rainfall run-off is 0.08 MGD. This
run-off is based on 40 inches of rain per year with 50% run-off. During winter,
freeze conditioning agents (i.e. diethylene glycol) may be added to coal by a vendor prior to
shipment or sprayed on the coal pile to prevent freezing. Based on an application rate of two
pints of 50 ppm diethylene glycol per ton of coal and 10,000 tons of coal per train load,the
addition of

freezing agents will not significantly alter the coal pile run-off waste stream and the discharge
of the lined retention basin at Outfall 006.
Floor wash water from equipment in the coal handling area and the remaining drainage from the
coal yard flows to the coal yard sumps where it is then pumped to the lined retention basin.
An anhydrous ammonia vapor suppression system is used in case of emergency release from the
anhydrous ammonia tanks. The system is set to activate at a concentration of 300 ppm of
ammonia. During normal operations intermittent low volume discharges of ammoniated water
generated during product delivery and quarterly system testing offloading of anhydrous
ammonia is collected in two aboveground collection tanks. These tanks are refreshed by adding
water and draining tanks simultaneously until conductivity is lowered. For an emergency
situations the water is collected in the tank farm containment and then drained through the sump
into the North coal yard sump where it is pumped to the lined retention basin. Service water is
pumped from Belews Reservoir.
Consolidated Sump
The consolidated sump includes wastewater from the sanitary waste system, the stormwater
collection pond, the limestone unloading facility sump and leachate from the dry fly ash and
gypsum landfills. The wastewater is snet to the lined retention basin.
The sanitary waste for the plant received primary treatment in a 600,000 gallon capacity
aerated lagoon. The lagoon discharges to a concrete chlorine contact chamber. To polish the
effluent, the sanitary waste system routes a circuit of water treated with chlorine to the
consolidated sump which is routed to the lined retention basin. The expected flow from
the sanitary treatment system is less than 10,000 gallons per day.
The stormwater collection pond collects stormwater run-off form the gypsum and
limestone stockpiles as well as some of the limestone track area around the unloading
facility. If the pumps for the sump fail, there is an overflow to Belews Reservoir,
possibly resulting in intermittent discharge.
There are two on-site landfills at Belews Creek, the FGD Residue landfill and the Craig Road
Ash landfill. These landfills are located southeast of the power station. The leachate and the
contact stormwater from these landfills is collected and pumped to the lined retention basin.
The FGD Residue landfill accepts gypsum. The Craig Road Ash landfill stores flyash, gypsum,
that is not suitable for beneficial use and clarifier sludge from FGD wastewater
treatment system. This material is filter pressed before it is placed in the landfill. Both
landfills began operation in 2008.

Fish Tissue Monitoring of the Dan River Near Belews Creek Steam Station(2019-2022)
Belews Creek Steam Station
1 Introduction and Background
Duke Energy Carolinas(DEC) owns and operates the Belews Creek Steam Station (Belews), a coal-fired
and natural gas-fired electricity generating facility located in Stokes County, North Carolina. Coal
combustion residual materials historically have been managed in the station's ash basin which received
fly ash and bottom ash through hydraulic sluicing. Deposition of waste streams into the ash basin ceased
on March 27, 2019, in preparation for ash basin closure. However,Outfall 006 continues to discharge
water from the ash basin to the Dan River as part of the closure process.As such,the National Pollutant
Discharge Elimination System (NPDES)Wastewater Permit for Belews (No. NC0024406,Section A. 18)
requires DEC to:
"...conduct fish tissue monitoring annually and submit the results with the NPDES permit renewal
application.The objective of this monitoring is to evaluate potential uptake of pollutants by fish
tissue near the ash pond discharge.The parameters analyzed in fish tissue shall include arsenic,
selenium,and mercury. The monitoring shall be conducted in accordance with the sampling plan
approved by the Division."
A study plan was submitted to,and approved by,the North Carolina Department of Environmental
Quality(NCDEQ) in 2019(Duke Energy 2019a).The study was designed to evaluate the potential uptake
of arsenic,selenium,and mercury(metals commonly associated with coal ash) in fish tissue with an
upstream/downstream monitoring approach.This report summarizes fish tissue monitoring results in
the Dan River near Belews during the NPDES permit term (2019-2022).
2 Methods
2.1 Study Site
Fish were collected from two areas on the Dan River(Figure 1-1)for trace element analysis of muscle
tissue. Area UP was located approximately 10.5 km upstream of the Belews ash basin discharge to serve
as a reference to monitor background trace element concentrations in fish muscle tissue.Area DN was
located approximately 14.5 km downstream from the Belews ash basin discharge to monitor potential
uptake of trace elements in fish muscle tissue.

2.2 Field Collection
Fish were collected for trace element tissue monitoring following the appropriate Duke Energy
procedures under Duke Energy's North Carolina Biological Laboratory Certification (Huntersville, NC
certification 008). Fish were collected using boat electrofishing, identified to species, measured for total
length to the nearest millimeter,weighed to the nearest gram, and marked with a unique tag identifier.
Fish were then placed in a labeled (sample date,sample location,facility,etc.) bag on ice while in the
field. Bags were sealed and transferred to a deep freezer at the end of the sampling day until processed
for analysis.
Sunfish (Lepomis)and suckers(Moxostoma)were targeted for collection based on prior sampling
experience, likely availability, potential for human consumption,and general trophic level. Duke Energy
personnel collected six individuals of each taxa from each sampling area. Individuals retained for
analysis were those considered of sufficient size for human consumption (>_60 g). As recommended by
the US Environmental Protection Agency(USEPA),fish were retained such that the size of the smallest
individual would not be less than 75%of the total length of the largest fish within each genus group
when possible (USEPA 2000).

2.3 Laboratory Analysis
Fish were processed for metals analysis at the Duke Energy Trace Element Laboratory located in New
Hill, NC. Fish were thawed and skeletal muscle was removed using a carbon-steel scalpel. Muscle tissue
from each individual fish was homogenized,weighed to the nearest 0.001 g,and dried to a consistent
weight in a desiccator.The dried weight was recorded and used to calculate a dry weight to fresh weight
ratio for that fish.Approximately 0.1 g of dried tissue was analyzed for each fish using X-ray
fluorescence.Quality control was achieved utilizing analytical standards, replicates, and certified
reference materials. Results below the lab reporting limit were set to the reporting limit for analysis.
3 Results and Discussion
During the study period (2019-2022),97 individuals representing five species were captured and
analyzed from the Dan River(Table 3-1).These species included Bluegill Lepomis macrochirus, Redbreast
Sunfish L. auritus,Golden Redhorse Moxostoma erythrurum, Notchlip Redhorse M. collapsum, and V-lip
Redhorse M.pappillosum.A full list of individual fish and associated trace element concentrations is
presented in Appendix A.

3.1 Arsenic
All fish collected during 2019-2022 were below the USEPA screening value for recreational anglers of
1.2 µg/g(fresh weight)for arsenic(USEPA 2000; Figure 3-1).
3.2 Mercury
No fish collected during 2019-2022 were above the USEPA screening value for recreational anglers of
0.4 µg/g(fresh weight)for mercury(USEPA 2000; Figure 3-1). One fish,a Notchlip Redhorse from UP,
had a concentration of 0.40 µg/g. Since this fish was collected upstream of Belews,the mercury present
in this fish's muscle tissue was not likely related to station operations.
3.3 Selenium
All fish collected during 2018-2022 were below USEPA screening value for recreational anglers of 11.3
µg/g(dry weight)for selenium (USEPA 2016; Figure 3-1).

4 Summary
All fish collected during the 2019-2022 study period were below the USEPA screening levels for
recreational anglers for arsenic and selenium. One sucker had a mercury concentration equal to the
screening level for mercury. However,this individual was collected upstream of the ash basin at Belews.
Additionally, concentrations of trace elements in fish tissues were similar between the upstream
reference area and the area downstream of the Belews ash basin.These results are similar to those
reported for the Dan River near Belews since 1984 (Duke Energy 2014,2019b).

(1)ND=Not detected at or above the limit of quantitation(LOQ).
(2)TDS samples were reveived at correct preservation temperature and stored inside a refrigerator at the lab.That refrigerator failed to maintain a temperature of<6 degrees Celsius over the weekend.
Samples were moved to an adequate refrigerator upon discovery of the elevated temperature;however,teh samples were exposed to elevated temperature for an unknown duration over the weekend.
(3)Unnamed tributary to the Dan River was sampled during instream monitoring until 6/2020;sampling disscontinued due to cessation of the discharge from all three outfalls(i.e.,003 003A,and 111).
(4)Outfall 003 was retired in fall 2020 and re-reouted to Outfall 006;therefore,the downstream sampling location was moved to B 2_PINE_HALL_BRG to capture the ash pond discharge associated with Outfall 006.
(5)Major permit modification(NC0024406)became effective 4/1/2021 and required sampling at approximately 250 meters downstream of Outfall 006(i.e.,B 2_DN2 INST).
