Permit Renewal and Amendment to Pending Major Modification Application
Dear Mr. Poupart:
Duke Energy Carolinas (Duke) requests the subject permit be renewed and reissued. The above referenced permit
expires on February 28, 2017. This request is in addition to the currently pending request for modification of the
subject NPDES permit dated July 29, 2014. As mandated by North Carolina Administrative Code i5A NCAC
2H.0105(e), this permit application is being submitted at least 180 days prior to expiration of the current permit.
Please find enclosed one signed original and two copies of the NPDES renewal application, which includes the
following items:
• EPA Form I;
• EPA Form 2C;
• Attachment 1 - Site Map showing the location of all Outfalls (internal and final);
• Attachment 2 -• Current and Future Waste Flow chart and description of waste flows through the facility in
accordance with EPA Form 2C Item II -A;
• Attachment 3 - Narrative description of sources of pollution and treatment technologies in accordance with
EPA Form 2C Item II -B;
• Attachment 4 - Alternate Schedule Request for 316(b);
• Attachment 5 - Alternate Steam Electric Effluent Guidelines (ELG) Schedule Justification;
• Attachment 6 - Arsenic, Selenium & Mercury Monitoring in Fish Muscle Tissue from the Dan River, NC;
• Attachment 7 - Assessment of Balanced and Indigenous Populations in Belews Reservoir;
• Attachment 8 —Aerial Photo Future Retention Basin Location
• Attachment 9 — Ash Basin Free Water Volume Calculation
Condition A(9) of the current permit requires that Belews Creek Steam Station (BCSS) comply with the Cooling
Tower Intake Structure Rule per 40 CFR 125.95. As allowed under 4125.95(a)(2), Duke requests an alternate
schedule for the submission of the applicable 316(b) information for Belews Creek (Attachment 4 -- Alternate
Schedule Request for 316(b)).

Condition (12) of the current permit requires BCSS to conduct fish tissue monitoring near ash pond discharge
(Outfall 003) once during the permit term and submit the results with the NPDES permit renewal application. The
attached report, Attachment 6 — Arsenic, Selenium, and Mercury Monitoring in Fish Muscle Tissue from the
Dan River, NC, contains fish tissue sampling data collected in 2014.
Condition A(15) of the current permit for BCSS requires that Duke request a continuation of the 316(A) thermal
variance in accordance with 40 CFR Part 125, Subpart H and Section 122.21(1)(6). The reapplication shall include
a basis for continuation such as:
I. The permittee must request the variance be continued.
Response: Duke hereby request continuation of the 316(a) variance reflected in the reissued Permit
for the Belews Creek Steam Station.
2. Plant operating conditions and load factors are unchanged and are expected to remain so for the term of
the reissued permit.
Response: BCSS operating conditions and load factors are unchanged and are expected to remain so
for the term of the reissued permit.
3. There are no changes to the plant discharges or other discharges in the plant site which could interact with
the thermal discharges.
Response: There have been no changes to BCSS discharges since the current NPDES permit
issuance in 2012.
4. There are no changes to the biotic community of the receiving waterbody which would impact the
previous 316 (a) variance determination.
Response: As determined by Duke's environmental monitoring, since issuance of the current
NPDES permit there have been no changes to the biotic community of Belews Lake
which would impact the previous 316(a) determination.
The attached report, Attachment 7 - Assessment of Balanced and Indigenous Populations in Belews Reservoir,
indicates the continued existence of a healthy aquatic population in Belews Reservoir. Therefore, this report also
supports renewal of the current alternate thermal monitoring requirements of Outfall 001.
This permit renewal request includes modifications to the treatment system and discharges that will be necessary to
comply with recently enacted laws and regulations including the Federal Stearn Electric Effluent Guidelines (ELG),
Federal Coal Combustion Residual (CCR) rule, the North Carolina Coal Ash Management Act of 2014 (CAMA)
and HB 630 of 2016. With reissuance of this permit, Duke Energy requests that NCDEQ staff incorporate the
following changes in the renewed NPDES permit:
1. Duke requests an alternate compliance date for compliance with Steam Electric Effluent Guidelines in
accordance with the request found in Attachment 5 - Alternate Steam Electric Guidelines (ELG) Schedule
Justification.
2. Duke intends to construct a new, lined retention basin to treat flows currently directed to the active ash
basin with the exception of ash sluice wastewater. CAMA and CCR rule will prohibit continued ash
sluice wastewater flows to the existing ash basin at BCSS. Projects are underway to convert ash handling
of all ash (both bottom and fly ash) to 100% dry handling and disposal systems at BCSS. The newly

Belews Creek Steam Station NPDES Renewal Application

Page 3 of S
constructed retention basin will discharge through Outfall 003. Duke has included a process flow diagram
of the future wastewater flow on the site to help with visualizing these changes (Attachment 2 — Current
and Future Flow chart and description of waste flows through the facility).
The lined retention basin will be approximately I I acres in area and have the capability to have addition
of flocculent and pH adjustment chemicals. The retention basin will consist of two basins: primary and
secondary. The primary basin is where the majority of any solids settling will occur, while the secondary
basin provides adequate retention period for settling of fine particles. Additionally, the retention basin
will have a cell where various vacuumed sediments and solids can be decanted prior to disposal of
materials into onsite landfill.
A holding basin will be constructed for high volume flows such as air heater washes, process washes, etc.
The holding basin will be designed for batch processing and will be approximately 7 acres in area. The
holding basin will have a chemical feed system for adjusting pH and adding polymer to enhance settling.
Treated wastewater will be transferred to the primary basin of the retention basin.
An emergency overflow will be constructed in the retention basin as a structural safety measure to allow
for controlled release in the event of meteorological event in excess of a design storm. It is anticipated
that any release from this basin would be very infrequent. Duke requests that the emergency overflow
to the existing effluent channel be listed as a contributing flow to outfall 003 as part of the renewal.
An aerial photo with planned location of the basin can be found in Attachment 8.
3. To comply with Federal ELGs for the bottom ash system, there is an allowance to route the bottom ash
sluice water to the FGD system, BCSS will reroute the bottom ash sluice water to the FGD system at a
future timeframe. Bottom ash from the boilers will be sluiced to submerged flight conveyors and
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.
4. Duke intends to add an ultrafiltration system to the existing FGD wastewater treatment system at a future
timeframe to comply with Federal ELGs for FGD wastewater.
5. Duke requests specific authorization that upon ceasing flows to the ash basin, decanting and dewatering of
the basin through existing NPDES Outfall 003 can occur. Specific authorization for decanting and
dewatering is a condition currently in the NPDES permit at Sutton and Marshall. Duke requests specific
authorization that the ash basin may be decanted and dewatered and an explicit statement of the permit
limits associated with that activity. A characterization of the ash basin interstitial water has been
previously provided July 22, 2015. Decanting and dewatering will ultimately flow to Dan River.
6. BCSS uses an anhydrous ammonia vapor suppression system in case of unintended release of anhydrous
ammonia from the six 60,000 gallon anhydrous ammonia tanks. In the event of an emergency operation
of the system due to a release of anhydrous ammonia flow from the vapor suppression system will flow to
the coal yard sump where it will be pumped to the ash basin and will potentially contain significant
concentrations of ammonia. Upon completion of the retention basin, test flows and emergency operation
flows will be directed to the retention basin as described in item #2. Vapor suppression system tests are
conducted quarterly. Flow rate for Vapor Suppression system maintenance testing will be approximately
172 gallons per minute. Actual flow rate for emergency operation of the vapor suppression will be
determined by emergency. Duke requests concurrence in the permit that any impacts associated with
the emergency operation of this system do not constitute a violation of the permit. Duke request

this flow be added to the list of flows tributary to Outfall 003 and, upon completion, the new
retention basin described in item #2 if this submittal.
7. Duke Energy is currently designing an extraction well system to provide accelerated groundwater
remediation. The extracted groundwater will be treated prior to discharge through outfall 003. Treatment
of the discharge may be provided by introducing the groundwater as a waste stream to the ash
basin/retention basin or a new direct groundwater treatment system.
8. Area of Wetness (AOW) Permit coverage Disposition — Duke has previously notified DEQ of, and/or
requested permit coverage for AOWs at BCSS, as set out in the following table.
Date of Notification/Permit Request
Affected AOWs
July 29, 2014
S-1 to S -I 1
October 3I, 2014
A to 1, HD -01 to HD -27, Parshall Flume, TF -01 to
TF -03
January 8, 2106
S-12 to S-14
June 1, 2016
S -14, S-15
AOWs designated as A to 1, HD -01 to HD -27, TF -01 to TF -03, and the Parshall Flume have been
eliminated or consolidated as part of an engineered weighted filter overlay project which flows to outfall
003 via the existing effluent channel (from the point of origin to the point of discharge) established in
I984 when the ash basin discharge was rerouted from Belews Reservoir to the Dan River. Duke requests
that the conveyances carrying these flows also be deemed effluent channels from their point of origin to
the point where they flow into the main effluent channel to the Dan River.
Based upon further review, Duke withdraws requests for coverage from areas previously identified
at S-01, S-03, S-04 and S-05. This request is based on location of the respective AOW's and/or
review of sampling data that confirms the lack of pollutants associated with plant activities being
released to Waters of the State from these points. Duke requests that DEQ provide concurrence or
acknowledgement of this request in the NPDES Fact Sheet for the permit.
Duke requests permit coverage for the remaining AOWs as follows:
• S-10, S-11 and S-15. All of these points commingle below the ash basin dam at the point
identified as S-15. Duke requests effluent channel designation from the point of origin of
each of these flows to the point identified as "S-15" on our AOW map where these flows
enter the preexisting effluent channel to the Dan River. Consequently, Duke requests that
all flows contributing to S-10, S-11 and S-15 be identified in the permit or fact sheet as
contributing flows to NPDES Outfall 003.
• S-06 and S-12. These two points commingle at the point identified as "S-6". Consequently,
Duke requests effluent channel designation from the point of origin of these flows to point
where they enter Belews Reservoir.
• S-13 and S-14. These two points commingle at the point identified as "S-14". Consequently,
Duke requests effluent channel designation from the point of origin of these flows to point
where they enter Belews Reservoir.
• S-02, S-07, S-08, and S-09. Duke requests effluent channel designation for S-02 from the
point of origin to the point where this flow enters the Dan River. Duke requests effluent

channel designation for S-07 from the point of origin to the point where this flow enters
waters or the State. Duke requests effluent channel designation for S-08 and S-09 from the
point of origin to the point where these flows enter Belews Reservoir.
Finally, Duke requests notification that this application is complete.

PART C - If you are a primary Industry and this outfall contains process wastewater, refer to Table 2e-2 in the instructions to determine which of the GC1MS fractions you must test for. Mark 'X7 in column 2-a for all such GCfMS
fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfafls. and nonrequfred GCIMS
fractions), mark 'X* In column 2-b for each pollutant you know or have reason to believe Is present. Mark 'X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must
provide the results of at least one analysis for that pollutant If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater. If you mark column 2b for acxolein, acrylonitrile. 2.4 dinilrophenol, or 2-methyl4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or
briefly describe the reasons the pollutant Is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (aff 7 pages) for each Outfall. See inst(uctions for

Project Number: J16040176
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. The sample
receiving date is documented in the header information associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved NELAC standards, the
Shealy Environmental Services, Inc. ("Shealy") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPs), and Shealy
policies. Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below.
If you have any questions regarding this report please contact the Shealy Project Manager listed on the cover page.
Low Level Mercury Analysis - Method 1631 E
The MS/MSD associated with sample -002 had recoveries of 74% and 68% respectively and a RPD of 10%. The RPD and the MS recovery was
within control, however the MSD had failed QC criteria low. The sample, MS and MSD were reanalyzed a second time. The second analysis came
back with the same results of 74%(MS), 68%(MSD), and 10&(RPD). The RPD and the consistent results show demonstrated matrix effect. No
further corrective action taken.
Volatile Organic Analysis - Method 624
The LCS associated with batch 14778 had Acrolein recovered above thecontrol limits. This demonstrates a high bias on analytical results. There
were no detections for Acrolein in the samples associated with this batch; therefore, data quality is not impacted.
Semivolatile Organic Analysis - Method 625
Samples -001, -005: The samples were re -extracted due to several compounds being recovered below the control limit in the LCS. 2-
Chloronaphthalene and Hexachloroethane were recovered below the control limit in the MS associated with re -extracted samples.

> Result is greater than value reported
BD Results are either below the MDC or tracer recovery is low
FA Failed analysis.
H Analytical holding time was exceeded
J Value is estimated
K Analyte present. Reported value may be biased high. Actual value is expected to be lower.
L Analyte present. Reported value may be biased low. Actual value is expected to be higher.
M M if above MDC and less than LLD
M RENT Result > MDC/CL and < RDL
N/A RPD or %Recovery limits do not apply.
NI See case narrative
ND Analyte concentration is not detected above the detection limit
NJ Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier
Q One or more quality control criteria have not been met. Refer to the applicable narrative or DER.
R Sample results are rejected
U Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
UI Gamma Spectroscopy --Uncertain identification
UJ Gamma Spectroscopy --Uncertain identification
T Not considered detected. The associated number is the reported concentration, which may be inaccurate due to a low bias.

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more or %RPD not applicable.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than
five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of+/- the
RL is used to evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the QC Summary.

Electronic Packaging Comment
This data package was generated using an electronic data processing program referred to as
virtual packaging. In an effort to increase quality and efficiency, the laboratory has developed
systems to generate all data packages electronically. The following change from traditional
packages should be noted: Analystipeer reviewer initials and dates are not present on the
electronic data files. Presently, all initials and dates are present on the original raw data. These
hard copies are temporarily stored in the laboratory. An electronic signature page inserted after
the case narrative will include the data validator's signature and title. The signature page also
includes the data qualifiers used in the fractional package. Data that are not generated
electronically, such as hand written pages, will be scanned and inserted into the electronic
package.

Introduction
Belews Creek Stearn 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 effluent channel (Outfall 003). 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 Coolinm 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.

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 CooELig Water (RCW) System
"rhe 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
<957. 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 5360 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 to prevent corrosion. The primary
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 ash basin/retention basin (Outfall 003).
During a leak and/or routine maintenance, the concentration of the maintenance chemical will
not exceed the No Observed EtTect Concentrations (NOEC) at either Outfall 001 or 003.
Hydrozen 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 Flushinz/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 OutfaU 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.
Sulfur Dioxide is produced from the coal combustion process. The FGD system removes SO2 by a
reaction using a limestone -water slurry. The FGD system will collect the flue gas after it passes
through the electrostatic precipitator and route the gas to the absorber tank. 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 continually 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
(CaS03). This CaS03 slurry falls to the bottom of the tank where a stream of air is injected to
oxidize the slurry to form gypsum (CaSO4•H20). The gypsum slurry is drawn off the absorber tank
and pumped to a hydrocyclone 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 pH is adjusted, metal treatment and coagulation occurs. In the event
of a maintenance issue with the reaction tanks a bypass line will be installed to route the flow around
the reaction tanks to continue treatment further downstream of the reaction tanks. After the treatment
occurs in the reaction tanks, the wastewater is sent to two clarifiers in order to reduce the solid loading.
Once the wastewater leaves the clarifiers 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 the metal concentrations. The treated wastewater is mixed with the cooling water from the
heat exchanger in order to reduce the chloride concentration. This treated wastewater is then
discharged to the ash basin/retention basin via Internal Outfall 002.
The following chemicals are utilized in the FGD wastewater treatment system: hydrated lime, ferric
chloride, polymer, hydrochloric acid, and nutrients.

To comply with Federal Steam Electric Effluent Guidelines (ELG) for FGD wastewater, an
ultrafiltation system will be added to the existing FDG wastewater system at a future timeframe.
To comply with Federal ELG guidelines for bottom ash system, there is an allowance to route the
bottom ash sluice water to FGD system. BCSS will route the bottom ash sluice water to the FGD
system at a future timeframe. 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.
More detail on these two projects and projected timeframes can be found in attached Attachment 5 -
Alternate Steam Electric guidelines (ELG) Schedule Justification.
To comply with CAMA 2014 and Federal CCR rule, BCSS will reroute the FGD treated wastewater to
future retention basin at a future timeframe.
Outfall 003 —Ash Basin and Future Retention Basin
The ash basin accommodates flows from the power house sumps, yard holding sump, ash sluice lines,
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. Seepage from the
engineered toe drains and through the dam flow to the Dan River via the existing effluent channel to
Outfall 003. This includes seepage identified in permit application amendments in July 2014, October
2014, and December 2014.
The retention basin, upon completion will 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 (10 lbs) and sodium hydroxide (4L).
❖ 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 BlowinP
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 Conditioninz
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

Low volume Wastewater
❖ Groundwater (GH) 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.
❖ nl 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 is not operating, then the fly ash can be sluiced to the ash
basin. Bottom ash form the boilers is usually water sluiced to holding cells for recycling
activities per reuse permit #WQ0007211. In the case of equipment failure or immediately
following an outage, service water is used to sluice the ash to the ash basin.
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.
As a contingency measure, if the levels of regulated parameters are increasing one option that
may be periodically implemented is to sluice service water (from Belews Reservoir) to the ash
basin to co -manage the various waste streams that are discharging to the ash basin.
To comply with Federal ELG guidelines for bottom ash system, there is an allowance to route
the bottom ash sluice water to FGD system. BCSS will route the bottom ash sluice water to the
FGD system at a future timeframe.
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

Belews Creek Steam Station, Stokes County

August 2016
Page 7 of 9
freezing agents will not significantly alter the coal pile run-off waste stream and the discharge
of the ash basin/retention basin at Outfall 003.
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 ash basin/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 ash basin/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 pumped to a two train 18 acre Constructed Wetland
Treatment System (CWTS) prior to discharge to the ash basin/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 ash basin/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 ash basin/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.
Ash Basin Run-off
Natural drainage area of Ash Basin is 655 acres. Station yard drainage area pumped to the Ash
Basin is 87.6 acres. Based on forty inches of rain per year with fifty percent run-off and the
watershed area of the ash basin, the yearly average rainfall run-off to the ash basin is
approximately 0.47 MGD.

Groundwater Extraction Well Svstem
Duke Energy is currently designing an extraction well system to provide accelerated
groundwater remediation. The extracted groundwater will be treated prior to discharge through
outfall 003. Treatment of the discharge may be provided by introducing the groundwater as a
waste stream to the ash basin/retention basin or a new direct groundwater treatment system.
Boiler and Filter Cleaning Wastes
BCSS has two supercritical boilers that are cleaned on an as needed basis. Tube inspections are
done during outages to determine when cleaning is needed. The chemical cleaning wastes are
collected for off-site disposal by third party vendor. The chemicals and approximate amounts
for one boiler cleaning are as follows:
Chemical Amount
Hydroxyacetic Acid 50,312 lbs
Formic Acid* 20,598 lbs
Ammonium Hydroxide*(26°Bd") 2,063 lbs
Ammonium BiFlouride* 4,249 lbs
Hydrazine 718 lbs
Corrosion Inhibitor (Proprietary) 500 lbs
The Reverse Osmosis (RO) system is used to treat raw water from Belews Reservoir. The RO
system is cleaned approximately 4-6 times per year. The RO cleaning wastes are pumped to the
ash basin/retention basin. Chemical and approximate quantities for one RO cleaning are listed

*These chemicals are present in amounts greater than the reportable quantity as identified under
the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). If
a spill of any of these chemicals were to occur, in most cases, the spill would be routed to the
ash basin/retention basin for treatment. These chemicals are being identified to qualify for the
spill responsibility exemption under 40 CFR 117 and CERCLA. \
Hazardous and Toxic Substances Table 2c-3:
At BCSS, the potential for toxic and hazardous substances being discharged is very low. In reference
to Item V -D of Form 2-C, the substances identified under Table 2c-3 that may be in the discharge are as
follows:
Acetaldehyde, Asbestos, Benzoyl Chloride, Butyl Acetate, Cresol, Cyclohexane,
Cyclohexanone, Epichlorohydrin, Formaldehyde, Furfural, Monoethyamine, Naphthenic Acid,
Pyethrins, Styrene, Triethanolamine, Vanadium, Vinyl acetate, Xylene, and Zirconimum and
also during the course ofthe year products such as commercial cleaners and laboratory reagents
may be purchased which contain very low levels of a substance found in Table 2c-3. It is not
anticipated that these products will impact the ash basin/retentions basin's capacity to comply
with its toxicity limits, since their concentrations are extremely low.
40 CFR 117 and CERCLA Hazardous Substances:
The table below identifies hazardous substances located on-site that may be released to the ash
basin/retention basin during a spill in quantities equal to or greater than the reportable quantity
(RQ) levels as referenced in 40 CFR 117, 302 and 355. This list is being provided in order to
qualify for the spill report ability exemption provided under 40 CFR 117 and the Comprehensive

Attachment 4 - Alternate Schedule Request §316(b) of the Clean Water Act
Belews Creek Steam Station
Final regulations to establish requirements for cooling water intake structures at existing facilities
were published in the Federal Register on August 15, 2014 (i.e. regulations implementing §316(b) of the
Clean Water Act) with an effective date of October 14, 2014. Per §125.91(a)(1)-(3) Applicability, the
Belews Creek Steam Station (BCSS) is subject to the requirements at §125.94 through §125.99 (316(b)
requirements) based on the following:
— The facility is defined as an existing facility (i.e. commenced construction prior to January 17,
2002);
— The facility is a point source discharge;
— The facility uses a cooling water intake with a design intake flow (DIF) of greater than 2 million
gallons (MGD) to withdraw water from waters of the U.S.; and
— Twenty-five percent or more of the water withdraws on an actual intake flow basis are
exclusively used for cooling purposes.
Per §125.98(b) Permitting requirements, 316(b) requirements are implemented through the NPDES
permit. Facilities subject to the final rule are required to develop and submit application materials
identified at §122.21(r). The actual intake flow (AIF) of the facility determines which submittals will be
required. Facilities with an AIF of 125 MGD or less are required to submit material identified at
§122.21(r)(2)-(8), whereas, facilities with an AIF greater than or equal to 125 MGD are required to
submit materials presented in §122.21(r)(9)-(13), in addition to information identified at §122.21(r)(2)-
(8). The AIF withdrawn by the station from Belews Creek Reservoir is above the 125 MGD threshold;
therefore, Duke Energy is planning on completing the following 316(b) submittals:
• §122.21(r)(2) Source Water Physical Data
• §122.21(r)(3) Cooling Water Intake Structure Data
• §122.21(r)(4) Source Water Baseline Biological Characterization Data
• §122.21(r)(5) Cooling Water System Data
• §122.21(r)(6) Chosen Method(s) of Compliance with Impingement Mortality Standard
• §122.21(r)(7) Entrainment Performance Studies
• §122.21(r)(8) Operational Status
• §122.21(r)(9) Entrainment Characterization Study
• §122.21(r)(10) Comprehensive Technical Feasibility and Cost Evaluation Study
• §122.21(r)(11) Benefits Valuation Study
• §122.21(r)(12) Non -water Quality and Other Environmental Impacts Study
• §122.21(r)(13) Peer Review

The regulation states the owner of a facility whose current effective permit expires after July 14,
2018, must submit the above information when applying for a subsequent permit and the owner of a
facility whose current effective permit expires on or before July 14, 2018 may request an alternate
schedule for the submission of the above information. As allowed under §125.95(a)(2), Duke Energy
would like to request an alternate schedule for the submittals listed above. Duke Energy would like to
request the 316(b) submittals, with the exception of §122.21(r)(6) Chosen Method(s) of Compliance with
Impingement Mortality Standard, for BCSS be required with the subsequent permit renewal application
due after July 14, 2018. Since BCSS is subject to the entrainment best technology available (BTA)
determination, a compliance schedule to complete §122.21(r)(6) Chosen Method(s) of Compliance with
Impingement Mortality Standard will be requested to be included in the permit upon issuance of the
entrainment BTA determination. The alternate schedule request is justified based on the following:
— Information requested in §122.21(r)(2), (3), and (5) were completed under the remanded
rule; however, this information must be updated to reflect current operations and
information requested in §122.21(r)(4) is substantially different from the remanded rule.
— , Information requested in §122.21(r)(6) — r(12) are new provisions and these submittals must
be developed.
For the §122.21(r)(13) Peer Review, Duke Energy estimates this could take up to 12 months
to complete. This, also, takes into account the other six Duke Energy stations in N. Carolina
and two stations in S. Carolina that will be undergoing the peer review process concurrently.
— Additionally, the United States Environmental Projection Agency (USEPA) — Headquarters
(HQ) have indicated guidance is being prepared to assist in interpreting and implementing
the rule requirements, however, this guidance is not expected to be issued until the 316(b)
litigation is completed, which is not expected to occur until 2017.

Belews Creek Steam Station: Effluent Guidelines Rule
Justification for Applicability Dates
A. Introduction
Duke Energy (Duke) is working diligently to develop and refine an optimized schedule for the
installation and upgrades to wastewater treatment systems to comply with the Steam Electric Power
Generating Effluent Limitation Guidelines (ELG) at seven coal-fired stations in North Carolina. Duke
submits the following information as a justification for appropriate applicability dates for compliance
with the new Effluent Guidelines Rule (ELG Rule) (80 Fed. Reg. 67,838 (Nov. 3, 2015)) at Belews
Creek Steam Station (BCSS), located in Belews Creek, North Carolina.
BCSS consists of two coal fired generating units with nameplate generating capacities of 1,110 MW
each for a total of capacity of 2,220 MW. The station currently discharges treated bottom ash
transport water, and FGD wastewater. Under normal plant operations, fly ash is collected dry and
either disposed in a permitted on-site landfill or transported offsite for beneficial reuse. If the dry fly
ash collection system is not operating, the fly ash is sluiced to the ash basin in which the transport
water is treated in the ash basin and subsequently discharged through outfall 003. Bottom ash from
the boilers is sluiced with transport water to the ash pond. The transport water is treated by the ash
pond system and is discharged through outfall 003. The FGD blowdown flows to a physical /_
chemical treatment system followed by a biological treatment system and discharges through internal
outfall 002 to the ash basin.
The ELG Rule sets a range of possible applicability dates for compliance with the new BAT limits for
bottom ash transport water (zero discharge) and FGD wastewater (numeric limits for selenium,
arsenic, mercury, and nitrate/nitrite), as well for fly ash transport water (zero discharge). The
regulation provides that all permits issued after the effective date of the rule (January 4, 2016) should
contain applicability dates for compliance with the BAT limits, and that those dates should be "as
soon as possible" but not sooner than November 1, 2018 and not later than December 31, 2023.
For BCSS, since the plant's final NPDES permit will be issued after January 4, 2016, but before
November 1, 2018, EPA specifically instructs permit writers to "apply limitations based on the
previously promulgated BPT limitations or the plant's other applicable permit limitations until at
least November 1, 2018." 80 Fed. Reg. at 67,883, col. 1 (emphasis added). As the rule makes clear,
however, BAT limits may apply — depending on the individual circumstances of the facilities subject
to the rule — any time within the window of November 1, 2018 to December 31, 2023. In selecting an
appropriate applicability date for each waste stream subject to the new BAT limits, the permitting
authority is called upon to determine an "as soon as possible" date.
The ELG Rule provides a very specific definition for "as soon as possible." The permit writer — when
supplied with appropriate information by the permittee — must consider a range of factors that affect
the timing of compliance. Those factors are as follows:
(1) Time to expeditiously plan (including to raise capital), design, procure, and install
equipment to comply with the requirements of this part.
(2) Changes being made or planned at the plant in response to:

(i) New source performance standards for greenhouse gases from new fossil fuel -
fired electric generating units, under sections 111, 301, 302, and 307(d)(1)(C) of the
Clean Air Act, as amended, 42 U.S.C. 7411, 7601, 7602, 7607(d)(1)(C);
(ii) Emission guidelines for greenhouse gases from existing fossil fuel -fired electric
generating units, under sections 111, 301, 302, and 307(d) of the Clean Air Act, as
amended, 42 U.S.C. 7411, 7601, 7602, 7607(d); or
(iii) Regulations that address the disposal of coal combustion residuals as solid waste,
under sections 1006(b), 1008(a), 2002(a), 3001, 4004, and 4005(a) of the Solid Waste
Disposal Act of 1970, as amended by the Resource Conservation and Recovery Act
of 1976, as amended by the Hazardous and Solid Waste Amendments of 1984, 42
U.S.C. 6906(b), 6907(a), 6912(a), 6944, and 6945(a).
(3) For FGD wastewater requirements only, an initial commissioning period for the
treatment system to optimize the installed equipment.
(4) Other factors as appropriate.
40 C.F.R. § 423.11(t).
The wastewater treatment systems at BCSS will undergo significant modifications and in most cases
complete replacement to comply with the revisions to the ELG Rule. Duke would like sufficient time
to select, design and install the most cost effective technology at BCSS to comply with the ELG
limits and reduce the burden to the ratepayers. We have prepared a preliminary timeline for planning,
designing, procuring, constructing and optimizing the technology once it is selected, for each
applicable waste stream. Based on our preliminary analysis, we request the following applicability
dates:
— Bottom Ash Transport Water: To convert the wet bottom ash transport system at BCSS to a
closed loop system, Duke plans to install a remote mechanical drag chain system (RMDS).
Duke would like to request May 31, 2021 as the applicability date for the no discharge of
bottom ash transport water, assuming a permit effective date of December 1, 2016. Duke
anticipates that equipment will be installed by December 31, 2019 to comply with the North
Carolina -Coal Ash Management Act (NC-CAMA) and the Coal Combustion Residual (CCR)
rule. These rules, however, only regulate the material, not the water. As discussed below,
Duke will need a 17 month window to optimize the system to operate as a zero discharge
system. This additional time is needed to account managing the installation and optimization
of four RMDS being installed in N. Carolina simultaneously. In addition, the extent and
complexity of the permits required are unknown at this time. Duke, therefore, allocated 6
months to account for potential permitting delays.
— FGD wastewater: The FGD wastewater treatment system at BCSS contains the model
technology EPA used as the basis for the best available technology (BAT) limits for FGD
wastewater, physical / chemical treatment followed by biological treatment. However, the
BAT limits were based on data from BCSS and Allen Steam Station while the stations were
primarily using coal from the Central Appalachian region. Based on Duke's experience with
the treatment of FGD wastewater, the variability in the coal can affect the performance of the
biological treatment system. In a memorandum from EPA, Variability in Flue Gas
Desulfurization Wastewater: Monitoring and Response dated Sept. 30, 2015, EPA
2

acknowledges data from Allen and BCSS show selenium concentration can sometimes
become elevated. In addition, EPA stated "The coal characteristics could alter the
characteristics of the FGD purge stream...". EPA further stated plants should acquire
information on the variability of the system "over a long enough time that will included
variability in plant operations such as shutdowns, fuel switches (preferably for all fuel types
burned at the plant), variability in electricity generating loads, periods with high ORP, etc."
Given the fact BCSS may use a variety of fuels and recent data indicates the current system
would be challenged to meet the ELG limits for FGD wastewater, Duke would like to request
November 30, 2020 as the applicability date for the BAT limits for FGD wastewater. This
time is necessary to investigate the variability in the system, evaluate technologies needed to
provide additional treatment to consistently meeting the ELG limits and design, install and
commission the additional treatment components.
Fly Ash Transport Water: Fly ash is handled dry during normal operation; therefore, Duke is
not requesting an applicability date for the zero discharge of fly ash transport water beyond
November 1, 2018.
The following provides necessary information justifying the requested applicability dates provided
above.
B. Bottom Ash Transport Water
As stated above, significant portions of the bottom ash transport system at BCSS will need to be
replaced to comply with the no discharge limit of bottom ash transport water (BATW). The rule
identified dry handling or closed-loop systems as the BAT technology basis for control of pollutants
in bottom ash transport water. Specifically, a mechanical drag system (MDS) was identified as the
technology basis for a dry handling system, where as a RMDS was identified as the technology basis
for a closed-loop system. Duke is planning on installing a RMDS at BCSS to handle bottom ash dry.
The system will be designed to operate in a closed-loop mode to meet the zero discharge limits for
BATW. Duke anticipates 54 months from the effective date of the permit will be needed to design,
install and commission the RMDS as a zero discharge system based on the following preliminary
timeline. It is important to note Duke will be installing RMDS at four stations in N. Carolina;
therefore, additional time is needed compared to a single installation to account for managing
multiple projects simultaneously.

1) The design tasks has been initiated and Duke estimates an additional 6 months from the
permit effective (assuming Dec. 1, 2016) will be needed to complete the design.
2) Even though is it estimated that commissioning and start-up can occur in 8 months, Duke
anticipates needing a 17 month window to obtain the necessary operating time at full load and
account for commissioning / optimizing occurring at multiple facilities simultaneously.
Assuming a permit effective date of December 1, 2016, Duke estimates the system can be installed
and operated to comply with the zero discharge limit of BATW on or before May 31, 2021. To
design, procure, construct and optimize the RMDS at BCSS to operate as a closed-loop system, the
following steps must be taken:
Design & EngineeringL
Duke has initiated the design phase, but, due to the simultaneous implementation of programs, such
as the CCR Rule and NC-CAMA across applicable sites in North Carolina, engineering and
technology resources are limited. Duke, therefore, estimates the design and engineering process will
take an additional 6 months from the permit effective date. Some of the activities within the water
balance and siting task will occur concurrently; however the design cannot be completed until the
siting task is completed. The permitting process, if necessary, will be initiated in the design and
engineering phase, but it is assumed permit receipt / approval will be conducted concurrently with the
design and procurement phase and will be completed prior to the construction phase. The following
tasks will need to be completed.
Water Balance
The first step in the design process of the RMDS is to develop a detailed water balance of the current
BATW. To operate the system as a 'zero discharge system, there is a balance between the inputs of
water into the system and the outputs of water through evaporation and bottom ash removal. This is
necessary to determine if any additional treatment of the BATW is needed to avoid increase in fines
and concentration of other constituents that could affect equipment operability.
In addition, several non-BATW waste streams are currently commingled and treated along with
BATW. The flow of these waste streams will be rerouted from the BATW system to a new
wastewater treatment system. This will require the streams to be characterized for both volumetric
flow and constituent make-up in order to size and design an appropriate treatment system. It is
important to note that not all waste streams discharge continuously or simultaneously. Some waste
streams discharge intermittently based on activity occurrence, such air preheater and precipitator
washes, while others may only discharge under certain rainfall events. In addition, many waste
streams do not discharge if the unit is not running. With most coal-fired units operating in an
infrequent mode, the opportunities to collect samples are limited and the operation schedule could
affect the schedule of this task.
Upon completion of the water balance, detailed engineering of the RMDS system and piping reroutes
of non-BATW can commence.
M

Siting
The RMDS will need to be sited appropriately to avoid any historical or current coal combustion
product disposal (CCP) sites and avoid construction areas that will be used to complete closure of the
ash basins at BCSS. In addition, Duke will attempt to site the system to avoid waters of the U.S.
(WOTUS). However, based on the final siting of the system, WOTUS may not be avoided, and
permits from the U.S. Army Corps of Engineers may be required.
Permitting
If WOTUS cannot be avoided, then permitting from the U.S. Army Corps of Engineers (USACE) will
be needed. At this time, it is unknown whether a USACE permit will be required or the type of permit
that may be required (nationwide permit (NPW) or individual permit). Duke, therefore, has included
12 months in the schedule to prepare and obtain any necessary USACE permits.
Once the RMDS is commissioned, the permitted discharge flows will change drastically. The amount
of water discharged could be reduced by as much as 85%. In addition, these flows typically were
treated along with the BATW in the ash basin. Duke, therefore, will need to design, and construct a
new treatment system for these low volume wastes. The size and technology of the treatment system
will be determined based on the water characterization study discussed above. Additionally, based on
the final siting of the low volume wastewater treatment system, a new outfall may be needed for the
discharge of the effluent from this new wastewater treatment system. With significant changes to the
characteristics of the permitted discharge, Duke anticipates a NPDES permit modification will be
required to revise the permit to account for the changes in flow and constituent make-up.
Even though the permitting task will be initiated during the design and engineering phase, it is
expected to continue through the procurement phase and up to the construction phase. In addition, the
extent and complexity of the permits required are unknown at this time. The required permits will be
evaluated during the engineering and design phase. Since the time needed to prepare the permit
applications and the time needed to receive the permits is uncertain, Duke allocated 6 months to
account for potential permitting delays.
Procurement
After the design is complete, Duke will initiate the process to procure the necessary outside resources
to construct and install the new wastewater treatment systems. This process will involve the following
steps:
— Evaluate potential vendors for proposal solicitation;
— Develop and submit request for proposal (RFP) to selected vendors;
— Conduct a review and vendor selection based on the received bids;
— Develop required contract documents;
— Acquire materials (potentially from overseas), which involves:
o Shipment, and
o Equipment Fabrication
— Fabrication and inspection of equipment.
5

RMDS have a fabrication queue that is dependent on total industry -wide demand. Duke, therefore,
has allocated 12 months to acquire the necessary materials.
Construction
Once all the necessary materials are procured, Duke estimates construction of the RMDS will take
approximately 13 months. In addition, the tie-in of the RMDS to each individual generating unit will
need to occur during outages, which are anticipated to occur between March to May and October to
November depending on generation demand.
Optimization and Operational Experience
As stated above, Duke is planning to have the equipment installed by December 31, 2019 at the latest
to meet the obligations under CAMA, in addition, to any CCR requirements. Again, these rules
regulate the bottom ash material, not the transport water. Given the system will continue to utilize
water to transport bottom ash, time will be needed to gain operational experience and optimize the
system to meet the zero discharge limit. Duke estimates a 17 month window will be required to gain
the necessary operational experience and fine-tune the system. The 17 month window is estimated
based on the potential that the station may only be operating at full load during the winter and
summer months and account for commissioning / optimizing occurring at multiple facilities
simultaneously. In addition, with NCDEQ approving the implementation date of January 31, 2021 for
Marshall Steam Station, Duke would like to stagger the commissioning / optimization activities for
BCSS by 4 months.
C. New Wastewater Treatment System
As discussed above, with the removal of several non-BATW waste streams from the bottom ash
transport system, a new wastewater treatment system will need to be designed and constructed for co -
treatment of low volume waste and other regulated process streams per the CCR rule, ELGs, and
NDPES permitting requirements. The activities associated with the new wastewater treatment system
will be conducted concurrently with the other design activities at the site. These waste streams are not
subject to the applicability date in the ELG rule, therefore, Duke is not requesting a compliance date,
but this task will need to be completed prior to the effective date of the zero discharge of BATW.
Duke anticipates 30 months will be needed to design, install and commission the new wastewater
treatment system, based on the following preliminary timeline.

D. FGD Wastewater
The FGD wastewater treatment system at BCSS contains the model technology EPA used as the basis
for the BAT limits for FGD wastewater, physical / chemical treatment followed by biological
treatment. However, the BAT limits were based on data from BCSS and Allen Steam Station while
the station was primarily using coal from the Central Appalachian region. Based on Duke's
experience with the treatment of FGD wastewater, variability in the coal can affect the performance
of the biological treatment system. This was evident based on data collected from the FGD
wastewater treatment systems at Allen and BCSS in 2014 and 2015 when the stations were using coal
from regions other than Central Appalachian. In a memorandum from EPA, Variability in Flue Gas
Desulfurization Wastewater: Monitoring and Response dated Sept. 30, 2015, EPA acknowledges data
from Allen and BCSS show the selenium concentration can sometimes become elevated. In addition,
EPA stated "The coal characteristics could alter the characteristics of the FGD purge stream...". EPA
further stated plants have between three to eight years to conduct the necessary studies to properly
design the treatment system and plants should investigate the variability of the FGD purge stream to
inform the design process. EPA went on to state plants should acquire information on the variability
of the system over a "long enough time that will included variability in plant operations such as
shutdowns, fuel switches (preferably for all fuel types burned at the plant), variability in electricity
generating loads, periods with high ORP, etc."
EPA further recognizes that designing, procuring, installing, and optimizing an FGD wastewater
treatment system is a complicated and time-consuming undertaking, involving much study and
careful planning. For example, EPA states:
"For plants that are planning to include fuel flexing in their operations, in the years
prior to the installation and operation of the FGD wastewater treatment system, the
plant should consider sampling the untreated FGD wastewater to evaluate the
wastewater characteristics that are present based on the differing fuel blends. Based
on those characteristics, the plant will be better able to design a system that can
properly treat its FGD wastewater given variability that might occur at the plant, and it
will be better prepared to adjust chemical dosages in the chemical precipitation system
to mitigate the variability in the wastewater that enters the biological treatment
system."
Response to Comments, p. 5-387.
EPA also states:
"While EPA has based the effluent limitations and standards for selenium and
nitrate/nitrite (as N) for FGD wastewater based on the performance of the Allen and
Belews Creek biological treatment systems, EPA does not contend that every plant in
the industry can simply take the design parameters from those two plants, install the
biological treatment system, and meet the effluent limitations. Each plant will need to
work with engineering and design firms to assess the wastewater characteristics
present at their plant to determine the most appropriate technologies and design the
system accordingly meet the effluent limitations. Therefore, some plants may need to
design the bioreactors to provide additional bed contact time (as provided by the
7

hydraulic residence time and volume of biomass and carbon substrate), while other
plants may find they need less."
Response to Comments, p. 5-389
Duke is requesting 48 months from the effective date of the permit to study the variability of the
system, evaluate additional treatment needs and design, install and commission additional treatment
components to meet the BAT limits based on the following preliminary timeline.

1) Duke is allocating a 12 month window to complete the commissioning and start-up under all
expected operating conditions from full load to partial load to periods of no load and under
varying fuel types.
Assuming a permit effective date of December 1, 2016, Duke estimates the system can be installed
and commissioned to meet the BAT limits on or before November 30, 2020. To design, procure,
construct and commission the FGD WWT system at BCSS, the following steps must be taken:
Design & Engineering
As with the RMDS, engineering and technology resources are limited due to regulatory requirements
for concurrent implementation of programs, such as the CCR Rule and NC-CAMA across applicable
sites in North Carolina. Duke is, therefore, estimating 21 months to complete the design and
engineering phase of the project.
Evaluate Variability in the System
As stated by EPA and with Duke's agreement, plants need to conduct studies of the variability of the
system over a long enough period of time that will include variability in plant operations such as
shutdowns, fuel switches (preferably for all fuel types burned at the plant), variability in electricity
generating loads, periods with high ORP, etc. to design an effective treatment system. With the need
to evaluate different fuel types to maintain economic viability of the station, Duke estimates at least
an additional 12 months after the permit effective date will be required to investigate variability in the
system.

Technology Evaluation
Duke has significant experience in the design, construction and operation of biological treatment
systems for selenium reduction. Based on Duke's experience, biological treatment alone may not be a
fool proof technology based on the characteristics of the coal. Duke, therefore, is obligate to evaluate
cost effective technology that ensures the FGD limits can be met under all conditions, including fuel
type, electricity load, etc. At a minimum, Duke will be evaluating the addition of ultrafiltration to the
backend of the treatment system. Duke will be working closely with utility organizations, such as the
EPRI, to identify other suitable technologies for the removal of selenium from FGD wastewater and
additional filtration steps that may be required to meet the limits. Duke estimates an additional 7
months after the completion of the investigation of variability in the system will be required to
complete the technology evaluation.
Engineering
Upon completion of the investigation of variability in the system and technology evaluation,
engineering and design of the system can be conducted and Duke has estimated two months for this
effort.
Procurement
After the design is complete, Duke will initiate the process to procure the necessary outside resources
to construct and install the new wastewater treatment systems. This process will involve the following
steps:
— Evaluate potential vendors for proposal solicitation;
— Develop and submit a request for proposal (RFP) to selected vendors;
— Conduct a review and vendor selection based on the received bids;
— Develop required contract documents;
— Acquire materials (potentially from overseas), which involves:
o Shipment, and
o Equipment Fabrication
— Fabrication and inspection of equipment.
Duke has allocated 8 months to acquire the necessary materials.
Construction / Tie In
Once all the necessary materials are procured, Duke estimates construction of the FGD WWT will
take approximately 7 months to complete. In addition, the tie-in of the additional components to the
existing FGD WWT will need to occur during outages, which are anticipated to occur between March
to May and October to November depending on generation demand.
Commissionina & Start -un
Duke estimates that commissioning and start-up of the FGD WWT will take 8 months to complete, 2
months for startup and 6 months for commissioning. Duke, however, is allocating a 12 month
window to complete the commissioning and start-up under all expected operating conditions from full
E

load to partial load to periods of no load and under varying fuel and other operating conditions. This
will allow the identification of necessary actions that need to be completed and necessary
communications protocol in order to maintain and operate the system to comply with the limits.
E. EPA Provided A Range of Applicability Dates To Allow For Coordination Across Regulatory
Requirements and to Promote Orderly Decisions
The steam electric industry is in the midst of major transitions driven by new environmental
regulatory requirements in the air, waste, and water arenas. In the ELG Rule, EPA explicitly
acknowledged the complications of planning and executing ELG retrofits while developing and
executing compliance strategies under the other rules. EPA made it clear that the range of
applicability dates provided in the ELG Rule are supposed to be implemented in a manner that avoids
stranded costs and promotes orderly decision making. For instance, EPA states:
"From an environmental protection/coordination standpoint, with the increased use of
flue gas desulfurization scrubbers and flue gas mercury controls in response to air
pollution -related requirements, this rule makes sense from a holistic environmental
protection perspective and from the perspective of coordinating across rules affecting the
same sector. This final, ELG controls the discharges associated with these particular
waste streams."
Response to Comments, p. 8-388.
EPA also states that the permitting authority may "account for time the facility needs to coordinate all
the requirements of this rule, along with other regulatory requirements, to make the correct planning
and financing decisions, and to implement the new requirements in an orderly and feasible way."
Response to Comments, p. 8-129.
At BCSS, we need to coordinate our ELG implementation strategy with CCR and NC-CAMA rules.
For both the CCR and CAMA rules, we are evaluating the current CCR ash pond to determine
whether the ponds meet the locational restrictions of 40 C.F.R. § 257.60 - .64. The future of the ash
pond under both of these rules will determine whether it is available or not to receive legacy
wastewaters (i.e., those wastewaters generated before the applicability date for bottom ash transport
water retrofits) and continue to receive non-BATW. In addition, as discussed above, the final
determination of the extent of the ash pond, as well as the closure method could have significant
ramifications for the siting of the RMDS.
F. ELG Implementation Should be Coordinated with the Clean Power Plan (CPP) to Avoid
Stranded Costs
The ELG Rule clearly contemplates that the compliance timelines for its requirements should account
for any applicable obligations under the CPP. However, the affected units at BCSS will not know
their individual obligations under the CPP until well after November 1, 2018. As promulgated by
EPA, the CPP's emission guidelines do not apply directly to units. Instead, states are responsible for
developing state plans setting forth requirements applicable to individual units that implement those
emission guidelines. These state plans are subject to review and approval by EPA. If EPA determines
that the state has not submitted an approvable plan, then EPA will promulgate a federal plan in its
10

place. The timeline the CPP provides for developing and reviewing these state plans involves
numerous steps.
The initial deadline for state plan submittal was September 6, 2016. 40 C.F.R. § 60.5760(a). The
vast majority of states were expected to seek and obtain a two-year extension for final state plan
submittal until September 6, 2018. See id. § 60.5760(b). However, the Supreme Court issued a stay
of the CPP on February 8, 2016. Thus, the timing of the requirements of the CPP is uncertain at this
time, as we wait further decisions by the Supreme Court. Duke would like to request the option to
revise the applicability dates for the ELG requirements if the stay of the CPP is lifted and the
operation of BCSS will be affected.
Statements in the Response to Comments regarding stranded costs apply to any rule, not just the CPP.
EPA explains in the Response to Comments that it provided flexibility in applicability dates so that
facilities could consider all new regulatory requirements and then have an adequate time to plan and
implement accordingly, and thus avoid stranded costs:
"EPA is sensitive to the need to provide sufficient time for steam electric power plants to
understand, plan for, and implement any changes to their operation to meet their
environmental responsibilities, and agrees with the commenter that transparency of
requirements is important for minimizing "stranded investments." ...Furthermore, as
described in the preamble, the final rule provides time for plant owners or operators to
implement changes to plant operations in order to meet the final limitations and
standards, as well as flexibility to permitting authorities in implementing the final rule.
The Agency specifically considered the timing of requirements of other environmental
regulations in establishing implementation requirements for the ELGs, in order to provide
steam electric power plants time to consider and implement their strategy for
compliance."
Response to Comments, p. 8-388.
Even though the implementation and effects of the CPP are uncertain, North Carolina Department of
Environmental Quality (NCDEQ) is justified providing flexibility in the applicability dates from other
regulatory requirements such as the CCR and NC -LAMA, as discussed above.
G. The Proposed Schedules Help To Maintain BCSS's Availability to the Grid, Which Promotes
Grid reliability
Duke developed the proposed BATW retrofit schedule and its applicability date with grid reliability
in mind. The dispatch of units at BCSS varies throughout the year. Typically at least one unit is
operating throughout the year and both units are typically dispatched from December to March and
June thru September. Therefore, the final tie-in schedule will avoid these months and more than likely
tie-ins will need to occur across more than one outage.
EPA explicitly notes that the permitting authority should consider grid reliability in setting
applicability dates: "EPA's decision is also designed to allow, more broadly, for the coordination of
generating unit outages in order to maintain grid reliability and prevent any potential impacts on
11

electricity availability, something that public commenters urged EPA to consider." 80 Fed. Reg. at
67,854, col. 2. See also Response to Comments, p. 8-138.
Also, EPA clearly anticipated that much of the new technology required for retrofits to bottom ash
transport water and FGD wastewater systems would be constructed in a manner that would not
interrupt routine facility operations, and then tied in during regularly scheduled plant or unit outages.
According to the preamble, the timing of the final rule "enables facilities to take advantage of planned
shutdown or maintenance periods to install new pollution control technologies." 80 Fed. Reg. at
67,854, col. 2.
EPA also recognizes that tie-ins of new equipment may need to occur across more than one outage.
EPA states: "the need to span installation of equipment over separate unit outages [is] a consideration
that can be incorporated into the permit writer's determination of the `as soon as possible' date,
assuming the plant provides documentation demonstrating such a need." Response to Comments, p.
8-54.

1.0 Introduction
Duke Energy owns and operates the Belews Creek Steam Station (BCSS) located on the upper Dan
River near Pine Hall in Stokes County, NC. The BCSS National Pollutant Discharge Elimination
System (NPDES) Permit (No. NC0024406 Section A 12) requires monitoring of trace elements
(arsenic, selenium, and mercury) in fish tissues near the ash pond discharge once per permit cycle. Fish
samples were collected in accordance to the Belews Creek Dan River annual monitoring program and
the resulting data are submitted in this report.
2.0 Study Site Description and Sampling Locations
Fish were collected from three locations on the Dan River (Figure 1). These locations were
upstream (A') and downstream (B and E) of the BCSS ash basin discharge to the Dan River.
3.0 Target Species
The target fish species were Golden Redhorse and Redbreast Sunfish. As recommended by the
US Environmental Protection Agency (EPA), an attempt was made to limit the smallest fish to
75% of the largest fish total length by species depending on availability (US EPA 2000).
4.0 Field Sampling Methods
Fish were collected using electrofishing procedures as specified in the DEP Biology Program
Procedures Manual (Procedure NR -00080, Rev. 1). DEP holds North Carolina Biological
Laboratory Certification # 006 from the North Carolina Division of Water Resources for its lab
located at New Hill, NC. Only live fish that showed little or no signs of deterioration were
retained for analysis. Retained fish were identified to species, measured for total length (mm),
weighted (g), individually tagged (Floy tags), placed on ice and transferred to a freezer within 24
hours of collection.
Surface water quality parameters consisting of temperature, pH, dissolved oxygen, specific
conductance and turbidity were recorded during each sampling, at each sampling location. Other
noteworthy environmental conditions including river flow conditions and weather conditions were
recorded and are available upon request.

5.0 Laboratory Processing and Arsenic, Selenium and Mercury Analysis
All fish samples were processed in the New Hill Trace Element Laboratory according to
procedure NR -00107 (Rev. 4) Trace Element Monitoring Laboratory Procedure. The processed
samples (lyophilized left axial muscle; right muscle occasionally included when needed) were
analyzed for arsenic, selenium, and mercury by x-ray spectrophotometry. Quality control was
achieved by use of replicates and certified reference materials. The remaining fish carcasses were
archived and will be kept for at least two years in the event that re -analysis is needed.
6.0 Data Analysis and Reporting ,
Arsenic, selenium, and mercury concentrations (converted to gg/g fresh weight) in the fish muscle
tissue collected during 2014 are shown in Table 1. In addition to the length and weight of each
fish, the dry -to -fresh weight ratios are presented to convert the arsenic, selenium, and mercury
concentrations fresh weight values back to dry weight values. The arsenic, mercury, and selenium
concentrations in fish tissues were low and show no indication of bioaccumulation from
operations of the BCSS ash basin discharge to the Dan River. In addition, all fish collected during
2014 were well below the US EPA Screening Values for Recreational Fishermen of 1.2 µg/g
(fresh weight) for arsenic (US EPA 2000), and below the NC human consumption advisory level
of 10 gg/g (fresh weight) for selenium. One Golden Redhorse from location B (downstream) had
a mercury concentration of 0.40 µg/g fresh weight. The remaining fish were below the were
below the North Carolina Health Directors Action Advisory Level of 0.40 pg/g fresh weight
(NCDHHS 2006),

EXECUTIVE SUMMARY
Aquatic populations residing in Belews Reservoir were adversely impacted by selenium
contained in ash basin effluent from the Belews Creek Steam Station (BCSS) from 1976 —
1985. During 1984, BCSS began dry fly -ash collection to eliminate most selenium and other
trace element inputs to the ash basin. The ash basin discharge was rerouted from Belews
Reservoir to the Dan River in 1985. Since that time, aquatic populations in Belews Reservoir
have recovered, and both Duke Energy and North Carolina Department of Environment and
Natural Resources (NCDENR) have acknowledged that balanced and indigenous populations
now reside in the reservoir. In addition to continued environmental monitoring in Belews
Reservoir, monitoring at locations uplake and downlake of the BCSS ash basin discharge in
the Dan River was initiated in 1984 and is ongoing. Duke Energy continues to monitor
aquatic populations per the approved monitoring program in both the Dan River and Belews
Reservoir. This report covers water quality, sediment chemistry, macroinvertebrate, and fish
community monitoring results from Belews Reservoir from 2011— 2015.
The BCSS is typically operated as a baseload generating station and the yearly capacity
factor (actual generation divided by potential generation, expressed as a percentage) during
2011 — 2015 has ranged from 65.4 to 82.5 %. During this period BCSS has fully complied
with the thermal limits of the station's NPDES permit. As in previous years, Belews
Reservoir Dam spillage remained relatively infrequent throughout 2011 — 2015. Controlled
spillway releases primarily conformed to a seasonal pattern with spillage occurring during
periods when the reservoir was near full pond.
Virtually all former ash sluice -related trace elements have been removed from the water
column with concentrations in Belews Reservoir during 2011 — 2015 less than applicable
state water quality standards, action levels, and often less than current analytical reporting
limits. Minor and gradual increases reported prior to 2011 for Belews Reservoir pH, specific
conductance, alkalinity, and major dissolved ionic constituents (i.e., calcium, magnesium,
chloride, and to slightly lesser extent, sodium, potassium, and silica) were not as evident in
2011 — 2015. The minimal, or lack of, increase was in part due to the relatively normal
rainfall patterns and resulting inflows to Belews Reservoir as compared to the drought
conditions evident in recent prior years 1998 - 2002 and 2007 — 2008. Overall, Belews
Reservoir nutrient concentrations remain relatively low throughout most of the reservoir,
which continues to be classified as an oligotrophic waterbody. Watershed inputs contribute
to increased nutrient concentrations in the uplake region.
iv

Concentrations of arsenic and selenium in Belews Reservoir surficial fine sediments during
2011— 2015 were similar to levels reported since 2000. Arsenic and selenium concentrations
in the deeper sediments of Belews Reservoir remain elevated relative to reference sites.
However, recent sediment arsenic, and particularly selenium concentrations downlake in the
shallower littoral areas are approaching the concentrations long -observed in the relatively
unaffected uplake area of the reservoir.
Belews Reservoir continues to support a diverse macroinvertebrate community reservoir -
wide. Taxa numbers were somewhat lower during, 2011 — 2015 than during the previous
five-year period, but were within historical ranges. All three macroinvertebrate sampling
locations periodically demonstrated higher densities than any recorded at these locations
since 1991.
Selenium concentrations in Belews Reservoir macroinvertebrates during 2011 — 2015
continued to indicate reduced levels and variability compared to results reported in the
1980's.. Comparable to historical trends, macroinvertebrates and plankton collected from the
uplake Location 405.0 generally had lower selenium concentrations than other locations.
Selenium concentrations in macroinvertebrates and plankton from downlake Locations 418.0
and 419.3 exceeded concentrations measured uplake, but showed the same decreasing trend
over time. The results of this ongoing monitoring program indicate that legacy selenium
concentrations in the lentic food web continue to decline, and the operation of BCSS is not
having a detrimental impact on the macroinvertebrate community of Belews Reservoir.
A total of 22 species represented bt seven families, dominated by sunfish (Centrarchidae)
were collected in the 2011 — 2015 fish community assessment. Fish survey metrics
associated with species composition, catch, and ecological function represent a self-
sustaining balanced and indigenous fish community in Belews Reservoir, were consistent
with previously reported data since 1994.
Uplake and midlake regions had the highest fish species diversity and catch, likely due to
higher relative concentrations of phosphorous, organic carbon, total suspended solids, and
turbidity from watershed inputs. Conversely, discharge and downlake regions had the lowest
fish species diversity and catch, reflective of oligotrophic conditions.
Q

Mean selenium concentrations in Redear Sunfish and Largemouth Bass remained well below
levels considered detrimental to fish reproduction and the 10-gg/g, wet weight, concentration
considered safe for human consumption.
Belews Reservoir continues to support a diverse fish and macroinvertebrate community
reservoir -wide. Results of long-term monitoring continue to indicate that a balanced and
indigenous aquatic community exists in Belews Reservoir.

CHAPTER 1
INTRODUCTION
HISTORY AND PHYSICAL DESCRIPTION
Historical Perspective
Belews Creek Steam Station (BCSS) is a two -unit, coal-fired electric generating plant located
on Belews Reservoir, in Stokes County, North Carolina. The reservoir, impounded primarily
to supply once -through condenser cooling water (CCW), first reached full pond in 1973,
followed by commercial operation of BCSS Unit 1 in August 1974, and Unit 2 in December
1975. Each 1,110-megawattl BCSS unit is cooled by CCW pumped at a maximum rate of
33.1 m3/s (1,170 cfs). As in the past, BCSS was operated as a baseload generating station
from 2011 - 2015.
In 1976 a sharp decline in the Belews Reservoir fishery was observed and eventually linked
with the discharge of BCSS ash basin effluent to the reservoir (Cumbie and Van Horn 1978;
Olmsted et al. 1986). A decline in the game fish population, documented reservoir -wide
except for a remote headwater area, was specifically attributed to reproductive impairment
and failure of recruitment caused by selenium. The impact of selenium on the Belews
Reservoir fishery was exacerbated by the lengthy retention time of the reservoir,
approximately 1,500 days under normal conditions. The extremely low rate of reservoir
outflow via dam spillage facilitated accumulation of selenium within the water column and
sediments, leading to selenium enrichment by the lowermost tier of the lentic food web, and
subsequent trophic transfer to sensitive receptor species (in particular, fish) via the food web.
By 1984, Duke Energy implemented dry fly -ash collection at BCSS to eliminate most wet
ash sluicing, and therefore reducing selenium and other trace element inputs to the ash basin.
To further facilitate the eventual recovery of the reservoir ecosystem, the ash basin discharge
to Belews Reservoir was rerouted to the Dan River in November 1985. Monitoring of water
and sediment chemistry, in addition to macroinvertebrate and fish populations, has been

ongoing since the termination of the ash basin discharge to the reservoir (Table 1-1 and
Figure 1-1).
Results of regular monitoring by Duke Energy have effectively documented the recovery of
the reservoir and its biological communities over time. Duke Energy and the North Carolina
Department of Environment and Natural Resources (NCDENR) have acknowledged that
macroinvertebrate and fish populations in Belews Reservoir have substantially recovered
from the selenium contamination episode and that a balanced and indigenous aquatic
community now exists in the reservoir. As required by the National Pollutant Discharge
Elimination System (NPDES) permit for BCSS (NCDENR 2005b, 2007a, 2009, 2012), this
report summarizes 2011 — 2015 results from the ongoing monitoring effort to assess water
and sediment chemistry, macroinvertebrates, and fish in Belews Reservoir.
In addition to continuing environmental monitoring in Belews Reservoir, monitoring by
Duke Energy at Dan River locations upstream and downstream of the re -located BCSS ash
basin discharge was initiated in 1984. Results of the Dan River monitoring program are in an
annual report submitted to NCDENR, and are not included in this report.
Study Area Description
Belews Reservoir was constructed principally as a cooling water source for BCSS, and has
no hydroelectric generation capability. The reservoir has a surface area of 1,563 hectares
(3,863 acres) at full pond elevation (221 m, or 725 ft msl). The upstream catchment is
relatively small, comprised of only an additional 1,630 hectares (4,028 acres; NCDENR
2010a).
Belews Reservoir is comprised of distinct regions, which in part relate to its principle
tributaries: the West Belews Creek arm; the Belews Creek arm; and the main body of the
reservoir, wherein their confluence lies (termed the "downlake" region in this and earlier
reports; Figure 1-1). The upper portion of the West Belews Creek arm of the reservoir
receives heated effluent from the BCSS once -through CCW system. The West Belews Creek
arm is physically separated from the remainder of Belews Reservoir, except for a 1.5 -km,
man-made canal that facilitates the return of heated CCW effluent to the Belews Creek arm.
1-2

Within the downlake region of Belews Reservoir, a high degree of uniformity in water
quality is normally evident. This is principally due to a forced circulation pattern induced by
the operation of the combined 66.3-m 3/S (2,340-cfs) capacity BCSS CCW pumps. The CCW
system flow rate significantly exceeds typical inflow rates from combined reservoir
tributaries (estimated to average 2.8 m3/s [98 cfs]; Cumbie 1978). Particularly during the
thermally stratified portion of the year, BCSS CCW pumping effectively maintains a
circulation pattern within the epilimnion of the downlake region. During the period of time
that ash basin effluent was discharged to Belews Reservoir in the 1970s and early 1980s, this
circulation pattern was instrumental in mixing diluted coal ash -associated trace elements
throughout the downlake region of Belews Reservoir.
Moving southward from the downlake region into the Belews Creek arm, beginning at about
1 km from the BCSS CCW discharge canal, one encounters a narrow portion of the reservoir
historically termed the "midlake" region. This region represents a transitional area, situated
between the reservoir's headwaters and the downlake region. In this portion of the reservoir,
the upper part of the water column typically reflects downlake water quality as influenced by
the edge of the BSCC thermal plume. However, the deeper portion of the midlake water
column typically reflects water quality more like that observed in the headwater portion of
the reservoir (i.e., cooler water, with greater concentrations of nutrients and suspended
solids). Following the fish population collapse that occurred in the 1970s and early 1980s,
this midlake region was considered a key indicator area in reservoir -wide assessments, and
was closely monitored to assess the early stages of recovery of the fish community.
The uppermost headwater section of the Belews Creek arm lies upstream and south of US
Highway 158, and has been termed the "uplake" region in this and other reports. Physical
restrictions to reservoir mixing attributable to the Highway 158 bridge and causeway, in
addition to two similar infrastructure "pinch points" (another road bridge and a former rail
crossing) located slightly downstream within the midlake region, serve to hydrologically
isolate the uplake from the downlake region. Because of these physical restrictions and the
nearby tributary inflow, the relatively shallow (i.e., < 5 m) uplake area was exceptional
compared to the balance of Belews Reservoir in retaining its indigenous fish community
throughout the 1970s and 1980s.
1-3

REGULATORY CONSIDERATIONS
Aside from the aforementioned requirement for ongoing environmental studies in both
Belews Reservoir and the Dan River, the BCSS NPDES permit establishes daily thermal
limits. Because Belews Reservoir was conceived and constructed as an industrial cooling
pond, however, regulatory thermal limits do not apply within the reservoir. The station's
NPDES permit establishes a discharge maximum thermal limit (32 °C, or 89.6 °F) at the
Belews Reservoir spillway for the protection of downstream water quality. The limit applies
during actual spillway releases (NCDENR 2005b, 2007a, 2009, 2012). Duke Energy
continuously monitors Belews Reservoir forebay (at the spillway) and actual spillage
temperatures to assure compliance with the permitted thermal maximum limit. Reference
reservoir temperatures are also continuously recorded from near -surface at a midlake site
(Location 419.2).
STATION OPERATION AND NPDES THERMAL COMPLIANCE
BCSS effectively maintained its role as a base load generating station throughout the most
recent five-year period. Annual net capacity factors (actual generation divided by potential
generation, expressed as a percentage) for the station were 82.5, 71.7, 64.5, 69.2, and 64.4 %
for the years 2011 — 2015, respectively (Table 1-2). Routine maintenance outages of
generating units were evident as unit -specific reductions in the monthly capacity data,
occurring throughout the five-year period.
During 2011 — 2015, BCSS complied with the thermal maximum permitted for Belews
Reservoir Dam spillage, 32 °C. As in previous years, Belews Reservoir Dam spillage
remained relatively infrequent throughout 2011 — 2015. Frequency of spillway operation
ranged from a minimum -of 20 days per year in 2015 to a maximum of 102 days per year in
2011. Controlled spillway releases primarily conformed to a seasonal pattern with spillage
occurring during periods when the reservoir was near full pond, i.e., normally winter -spring,
with spillage requirements typically triggered by short-term local precipitation patterns
(Figure 1-2).

2011— 2015 BELEWS LAKE MONITORING PROGRAM
The Duke Energy Belews Reservoir monitoring program remained unchanged following the
last reported results (Duke Energy 2011). The program encompasses water quality
monitoring, sediment, macroinvertebrate, and fish trace element screening,
macroinvertebrate and fish community assessments. The scope of annual monitoring
activities is provided in Table 1-1, with reference to sample locations identified on Figure 1-
1. The remainder of this report is dedicated to a summary and discussion of the 2011 — 2015
Belews Reservoir monitoring results.

CHAPTER 2
WATER QUALITY AND SEDIMENT CHEMISTRY
INTRODUCTION
This chapter summarizes the results of the continuing water quality and sediment chemistry
monitoring programs conducted at Belews Reservoir since 1977 and 1984, respectively. The
water quality and sediment chemistry portion of the Belews Reservoir monitoring program is
comprised of semi-annual (winter and summer) water quality sampling, and annual reservoir
sediment sampling. These programs have served to assess the effects of rerouting the BCSS
ash basin discharge away from Belews Reservoir. As discussed in Chapter 1, rerouting of
the ash basin effluent (and installation of a dry fly -ash collection system) was undertaken in
response to toxicity concerns caused by elevated concentrations of coal ash combustion trace
elements, principally selenium, in Belews Reservoir.
Previous research (Duke Power 1994, 1995, 1996, 1996b, 1997, 1998, 19995, 2000, 2001a,
2001b, 2002, 2003, 2004, 2005; Duke Energy 2006a, 2006b, 2007, 2008, 2009a, 2009b,
2010a, 2011b, 2012, 2013, 2014; Harden et al. 1988; Lewis et al. 1988) indicated that re-
routing the ash basin discharge has had minimal impact on the Dan River, but a distinct and
positive effect on Belews Reservoir water quality. Water column arsenic and selenium
concentrations in Belews Reservoir decreased substantially during the first year the ash pond
effluent was diverted to the river and have remained near or below detectable levels ever
since. Sediment trace element concentrations in the downlake areas of Belews Reservoir
continue to be elevated with respect to non -impacted uplake sites. However, data collected
over the past several years suggest that these downlake concentrations have substantially
declined in the littoral areas of the reservoir, while remaining elevated in the deepest regions.
2-1

MATERIALS AND METHODS
Field Methods
In-situ Belews Reservoir water quality was monitored at seven locations (Table 1-1 and
Figure 1-1) semiannually (summer and winter) during 2011 — 2015. Sample locations were
the same as those previously employed in past Belews Reservoir studies and comprise the
following: 405.0 (uplake); 419.2 and 419.3 (two midlake locations); 410.0 (BCSS condenser
cooling water [CCW] discharge confluence with the Belews Creek arm of the reservoir);
418.0 (BCSS CCW intake); 418.3 (former BCSS ash basin discharge); and 416.0 (forebay of
the Belews Reservoir Dam). In-situ analyses were performed by Duke Energy
Environmental Services personnel .2 Vertical profiles of in-situ parameters (temperature,
dissolved oxygen [DO], pH and specific conductance) were collected with a field -calibrated
Hydrolab DataSondeo. Profile sampling included surface (0.3 m) measurements, and, except
for the shallow cove Location 418.3, sequential measurements collected at one -meter
intervals, to within 0.5 in above bottom.
Water samples for laboratory analyses were collected with a Kemmerer bottle at surface (0.3
m) and approximately one meter above bottom, except for the cove location (418.3), where
only surface samples were obtained. Water samples for a wide array of analytes were
collected during 2011 — 2015 at all locations except Location 419.2, where only samples for
arsenic and selenium were collected. Samples for soluble nutrients (i.e., ammonia -N,
nitrite+nitrate-N, orthophosphate, and dissolved organic carbon) were filtered (0.45-µm) in
the field. All samples were preserved (acidified and / or iced) in the field immediately
following collection.
Sediment sampling for evaluation of selected trace element concentrations was conducted at
four Belews Reservoir locations during 2011 — 2015, and was similar to that described
previously (Duke Power 2001a; Duke Energy 2006a, 2011). In the main body of Belews
Reservoir, sediments were obtained from three sites corresponding to distinct bottom depths:
Location 417.1 (2 to 3 in deep); Location 417.2 (5 to 7 m); and Location 422.0 (25 to 30 m).
Uplake sediment samples (Location 405.0; 3 to 5 m) were also collected for comparative
purposes. Five replicate cores were obtained from each location. Cores were collected with

Quality (DWQ) under the Field Parameter Certification program (certificate number 5193).

a 50.8 -mm internal diameter Kajak-Brinkhurst gravity corer fitted with cellulose acetate
butyrate core liner tubes. Upon collection, sediment cores were sealed with polyethylene end
caps, with site water overlaying the intact water -sediment interface. Cores were maintained
in an upright position to preserve the sediment -water interface, stored on ice, and
subsequently refrigerated upon return to the laboratory.
Laboratory Analytical Methods
Water
Analytical methods and sample preservation techniques employed during 2011 — 2015 are
summarized in Table 2-1. The majority of laboratory water quality analyses were performed
by the Duke Energy Carolinas, LLC analytical laboratory, Huntersville, NC (NC Division of
Water Quality [DWQ] Laboratory Certification program, certificate number 248). Selected
parameters, however, were analyzed by alternate state -certified commercial laboratories.
Prism Laboratories, Inc., Charlotte, NC (NC DWQ certificate number 402) determined
biochemical oxygen demand (BOD), and turbidity analyses for all 2011 through summer
2015 samples.
Since 2001, trace element concentrations of water samples have been analyzed as "total
recoverable" elemental concentration, which incorporates a dilute acidic digestion of the
sample (USEPA 1994). This technique was distinct from the analytical method for trace
elements employed during the period 1988 — 2000, when acid -preserved samples were
analyzed by atomic absorption spectroscopy direct injection, i.e., samples were not acid -
digested.
Sediment
Upon return to the laboratory, fine-suspendable sediments were siphoned from the top 2-3
mm of each core, sieved through a 63-µm plastic (Nitex°) screen, and then deposited onto a
pre -weighed 0.45-µm Millipore® acetate membrane filter. Filters were subsequently dried at
room temperature and analyzed by non-destructive neutron activation analysis at the Nuclear
Services Laboratory, North Carolina State University, Raleigh, NC. Quality assurance
measures for sediment trace element concentrations (expressed as µg element/g sediment)
employed internal standards and National Institute of Standards and Technology or
International Atomic Energy Agency reference materials for calibration.
2-3

Hydrologic Data Methods
Hydrologic data (i.e. rainfall) were retrieved from two local area monitoring stations, a
National Weather Service (NWS) monitoring site at Greensboro, NC and a United States
Geological Survey (USGS) station near Pine Hall, NC. Belews Reservoir elevation data
were retrieved from the Duke Energy Plant Information (PI) system. Annual and monthly
rainfall totals and daily Belews Reservoir pond elevations are depicted graphically for use in
discussions of trends in water quality.
Water Quality and Sediment Data Analysis Methods
Data analyses employed both statistical and graphical methods. Water quality and sediment
analyte concentrations reported as less than method reporting limits, were set to the limit
prior to graphical display or statistical analysis. Time series plots were used to assess
seasonal and inter -annual trends in CCW and reservoir temperatures. Reservoir -wide
temperature and DO data collected semi-annually were assessed using both vertical profile
and areal contour plots. Box and whisker plots (showing median, 25% and 75% quartiles,
and data range) were produced for water chemistry analytes, by sample location and pre-
defined year groupings (i.e., during ash basin inputs: 1977 — October 1985; initial ecosystem
recovery period: November 1985 — 1995; and successive 5 -year reporting intervals: 1996 —
2000; 2001 — 2005; 2006 — 2010; and 2011 — 2015), to permit examination of spatial and
temporal trends. Graphical long-term temporal trending was used to facilitate examination of
hydrologic or other factors on selected water chemistry parameters.
RESULTS AND DISCUSSION
Regional Precipitation and Management of Belews Reservoir Surface Elevations
The five-year monitoring period summarized in this report exhibited precipitation patterns
(2011 — 2015) that were near normal in comparison to the two previously reported periods
that experienced some prolonged drought periods in 2002 - 2003 and 2007 - 2008 (Figures 2-
1 through 2-3; NCDC 2007-2015; USGS 2016). Local precipitation, as measured by the
National Weather Service (NWS) at Greensboro, NC and the (USGS) station near Pine Hall,
NC was at, or slightly above, normal for calendar years 2011, 2012, and 2015. Precipitation
was just slightly below normal for calendar years 2012 and 2014.
2-4

Belews Reservoir elevations were maintained closer to full pool elevation in the 2011 - 2015
monitoring period in comparison to the previous monitoring periods (Figure 2-4). This was
largely a result of more normal precipitation patterns in 2011 - 2015 relative to the previous
reporting period (2006 - 2010) that experienced prolong drought conditions from 2007
through 2008. Supplemental pumping in 2011 - 2015 also aided in maintaining pool
elevations in Belews Reservoir.
Water Quality Monitoring Results
Water Temperature
Seasonal ranges in Belews Reservoir water temperatures during 2011 — 2015 were consistent
with previously monitored years, as evident from CCW records, temperature profiles, and
isotherm plots (Figures 2-5 through 2-9; 2-15 through 2-24). Furthermore, temperature
profiles from 2011 - 2015 exhibited similar winter and summer thermal patterns
characteristic of Belews Reservoir that have been observed and discussed in previous reports
(Duke Energy 2006a, 2011).
Winter vertical temperature profiles measured downlake at the Belews Reservoir Dam
forebay (416.0) and BCSS intake (418.0) locations indicated typical near -uniformity with
depth, ranging from about 10.5 to 13.5 °C (Figures 2-10 and 2-11) [Note that winter 2014
profiles were collected in March where other years' winter monitoring was completed in
February. The March 2014 profiles reflect slight warming in the upper water column that
would be consistent with collecting this data later in the calendar year.]. Temperature
profiles at Location 410.0 (CCW discharge; Figure 2-12), and to a lesser extent Location
419.3 (midlake; Figure 2-13), reflect warming of the upper water column by the buoyant
thermal plume from BCSS, in both winter and summer monitoring events. Over the five-
year period, 2011 — 2015, minimum winter temperatures occurred reservoir -wide during the
winter of 2015.
The ranges of summer profile temperatures during 2011 — 2015 were generally typical of
long-term trends for each monitoring location (Figures 2-10 through 2-13). Main reservoir
(Location 416.0) surface temperatures were between 29.0 and 33.0 °C. The warmest summer
epilimnetic temperatures reservoir -wide were observed in August 2011 (38.6 °C) at the
confluence of the CCW connecting canal [i.e. Location 410.0 (Figure 2-12)]. Hypolimnetic
2-5

temperatures in mid -summer were indicative of preceding late winter water temperatures
(i.e., about 10 to 13.5 °C).
As previously reported in BIP reports (Duke Power Company 1996; Duke Power 2001a;
Duke Energy 2006a, 2011), changes in the summer physical -chemical structure of Belews
Reservoir were observed following installation of a hypolimnetic air injection system
designed to improve the efficiency of the BCSS CCW system. This air injection system,
installed in 1985 at a depth of 17 meters below full pond elevation, creates an up -welling of
cooler metalimnetic and hypolimnetic water for condenser cooling (Griggs 1985; Duke
Power Company 1996). In earlier years, summertime operation of the system effectively
deepened the late summer thermocline (i.e., region of maximum observed decline in
temperature per depth unit) depth by approximately seven to eight meters below that
observed previously (Figure 2-14). Similar thermal effects have been documented for other
waterbodies subjected to hypolimnetic aeration (Labaugh 1980; Schladow and Fisher 1995).
Significantly reduced operation of the hypolimnetic aeration system was reported previously
(Duke Energy 2011). Reservoir -wide summer temperatures and resulting thermocline depths
from 2011 - 2015 indicated limited, to non-existent, use of this system once again in the
current monitoring period. Reduced aeration' system operation has allowed a relatively
greater reserve of cooler water to remain available (from depths down to 17 meters) for an
extended period throughout the summer.
Two-dimensional contour plots of water temperature isotherms illustrate the relative
consistency in thermal gradients in Belews Reservoir. Besides the CCW thermal plume itself
(in the immediate vicinity of Location 410.0), the most extreme thermal gradient occurring in
wintertime occurs between the Belews Reservoir headwaters to downlake approximately 2
km into the midlake region of the Belews Creek arm of the reservoir, just above the vicinity
of Location 419.3 (Figures 2-15 through 2-19). During the summer stratified period, a
maximal thermal gradient generally occurs reservoir -wide, encompassing a vertical
differential of about 15 to 16 °C across an approximate 8-m to 10-m layer of water centered
near elevation 210 in msl (Figures 2-20 through 2-24). Summer isotherm distributions
indicate that uplake temperatures are only marginally cooler with respect to the main portion
of Belews Reservoir.
2-6

Dissolved Oxygen
Belews Reservoir epilimnetic DO profiles (Figures 2-25 through 2-28) consistently exceeded
the state water quality standard of 5 mg/L (NCDENR 2007b) during 2011 — 2015. Periodic
monitoring, most recently in 2009 by the North Carolina DWQ (NCDENR 2010a), has also
indicated adequate summer DO concentrations in the surface waters of Belews Reservoir.
Summer DO profiles from 2011 - 2015 exhibited a metalimnetic depression in oxygen
concentrations coincident with the thermocline depth, as has been reported previously (Duke
Energy 2011). This phenomenon, which is characteristic of southeastern reservoirs that
undergo pronounced seasonal thermal stratification, is caused by the thermocline acting as a
density barrier. This density gradient at the thermocline impedes vertical settling to the
extent that overlying oxygen -consuming material settles to this depth and subsequently
depletes the DO. During 2011 — 2015, metalimnetic DO depression was most clearly
demonstrated at Location 410.0 (Figure 2-27).
Two-dimensional contour plots of DO isopleths further illustrate the seasonal distribution of
DO throughout the reservoir in 2011 - 2015. Very little spatial differentiation in DO
concentrations were evident in winter due to virtually complete mixing of the water column
with reservoir -wide DO concentrations of 6 mg/L and above (Figures 2-29 through 2-33).
Summer 2011 — 2015 DO isopleths depict consistent prevalence of adequate DO
concentrations reservoir -wide in the epilimnion (Figures 2-34 through 2-38), but also
variation year -by -year in the degree of DO depletion in the deeper regions of the reservoir.
Water Chemistry
Spatial -temporal depictions of water chemistry parameters are provided in Figures 2-39
through 2-74. Earlier reports (Harden et al. 1988; Lewis et al. 1988; Harden 1991; Duke
Power Company 1996) noted changes in Belews Reservoir water quality, particularly in
decreasing levels of alkalinity, calcium, sulfate, and specific conductance, coincident with
the termination of ash basin discharges to the reservoir in late 1985. Changes were most
noteworthy at Location 418.3, a cove that formerly received ash basin discharge. Downlake
locations, where concentrations of constituents associated with ash pond effluent (i.e.,
dissolved minerals and trace elements) had never risen to the incipient levels measured at
Location 418.3, and have shown less dramatic, but consistent, declines over the years.
During 1996 — 2000 many water quality indicators were measured at levels similar to those
2-7

observed a decade after termination of ash pond sluice inputs to the reservoir (Duke Power
2001a). However, specific conductance and concentrations of potassium and sulfate
continued to decline at downlake and midlake locations. Reservoir -wide monitoring of water
column concentrations since 2000 has confirmed that declining trends formerly noted for
selected conservative mineral constituents have abated, and in some instances, concentrations
have actually increased in recent years, as influenced by repeated occurrences of drought
conditions in the watershed.
Reservoir -wide in situ pH measurements were consistent with the previous reporting period
values. Reservoir -wide pH measurements from 2011 - 2015 as with the previous monitoring
period were elevated with respect to data collected since 2000 (Figure 2-39). These pH shifts
can be driven by changes in major ion concentrations, which in turn are further influenced by
watershed meteorology (e.g., drought; Figure 2-40). For example, gradual increases in
Belews Reservoir calcium and until recent years, decreases in sulfate concentrations, appear
consistent with the observed temporal pH trends.
Specific conductance (Figures 2-41 and 2-42), alkalinity (Figures 2-43 and 2-44), calcium
(Figures 2-45 and 2-46), magnesium (Figures 2-47 and 2-48), sodium (Figure 2-49 and 2-50),
potassium (Figure 2-51 and 2-52), chloride (Figures 2-53 and 2-54), and silica (Figure 2-57
and 2-58) were fairly consistent with the previous reporting period. Specific conductance,
calcium, and chloride showed signs of continued, but extremely minimal, increases in these
constituents. However, alkalinity, magnesium, potassium, and silica during 2011 — 2015
appeared to remain constant compared to the previous reporting period. Overall, trends in
these parameters indicated the inflows (and supplemental pumping) to the reservoir were
sufficient in 2011 - 2015 to offset some of the minor increasing trends in these parameters
reported in recent monitoring periods as a result of prolonged drought conditions.
Belews Reservoir sulfate concentrations (Figures 2-55 and 2-56) peaked in the early 1980s as
a result of the introduction of ash pond effluents. Concentrations of sulfate were in steady
decline after the 1985 termination of the effluent until 1998. Subsequently, sulfate
concentrations have remained relatively stable, including through the 2011 - 2015 reporting
period.
Iron (Figure 2-59), manganese (Figure 2-60), and aluminum (Figure 2-61) concentrations
demonstrated either no or negligible decrease compared to recent years. Maximum
concentrations of these cationic metals have historically been associated with either reduced
2-8

redox conditions occurring seasonally in the hypolimnion, or samples containing higher
suspended solids concentrations, as typically collected uplake at Location 405.0, above the
Highway 158 bridge.
Concentrations of major nutrients (Figures 2-62 through 2-66) in Belews Reservoir have
historically been, and continue to be, consistently low and indicative of an oligotrophic
waterbody (Weiss and Kuenzler 1976; NCDEHNR 1992; NCDENR 2005a, 2010a).
Elevated and variable phosphorous, and to a lesser extent, organic nitrogen concentrations
are frequently encountered near the Belews Reservoir headwaters, in addition to deep
midlake samples typically influenced by headwater inflows. Watershed nutrient
contributions to Belews Creek are in part evidenced by water quality trends in Kernersville
Reservoir, located several kilometers southwest and uplake of Location 405.0 on the
uppermost reach of Belews Creek. That small water supply reservoir has exhibited increased
concentrations of phosphorus and total Kjeldahl nitrogen in recent years, spurring
undesirable algal blooms (NCDENR 2010a). Elevated phosphorus concentrations
encountered uplake, as influenced by Belews Reservoir headwaters, are consistent with
greater productivity, and higher number of fish species and biomass observed uplake
compared to further downlake regions (see Chapters 3 and 4). Similar uplake-to-downlake
differences were routinely observed for total organic carbon (Figure 2-67), turbidity (Figure
2-68), total suspended solids (Figure 2-69), and as mentioned previously, iron (Figure 2-59),
manganese (Figure 2-60), and aluminum (Figure 2-61).
Belews Reservoir aqueous trace element concentrations (Figures 2-70 through 2-74)
consistently remained below applicable state water quality standards and action levels
throughout 2011 — 2015 (NCDENR 2007b). Typical of previous monitoring, all aqueous
cadmium concentrations measured in Belews Reservoir during 2011 — 2015 were less than
the laboratory reporting limit (1 gg/L). Similarly, for lead, water column concentrations
were below reporting limits (1 gg/L). All total and dissolved copper concentrations
remained below 2 gg/L throughout the five-year period (with 81 % remaining below the
reporting limit of 1 gg/L).
Once -elevated aqueous arsenic and selenium concentrations measured at the cove formerly
receiving ash basin effluent (Location 418.3) dropped precipitously just two years after the
effluent was routed to the Dan River. Since the late 1980s, water column concentrations of
arsenic (Figure 2-70) and selenium (Figure 2-73) at all downlake and midlake locations have
declined to minimal levels, predominantly occurring below detectable quantities. During this
2-9

timeframe and inclusive of the 2011 — 2015 period, arsenic and selenium concentrations
measured in the water column downlake have remained undifferentiated from those
measured in the remote headwater portion of Belews Reservoir (Location 405.0). In fact,
during the 2011 - 2015 monitoring period 100% of the samples analyzed for selenium and 98
% of samples analyzed for arsenic were below analytical reporting limits (1 gg/L).
Sediment Arsenic and Selenium Concentrations
Distinct reservoir depth -dependent concentration differences in downlake Belews Reservoir
fine- (< 63 gm) surficial sediments have been noted historically, with deeper locations
concentrating significantly (a < 0.001) more of either trace element than progressively
shallower locations (Figures 2-75 through 2-78; Duke Power Company 1996, 2001a).
Cumbie (1984) and Harden (1991) reported this depth -associated correlation for Belews
Reservoir and hypothesized differential mobilization and deposition of selenium and arsenic -
containing material from shallow to deep areas of the reservoir. This process, termed
"sediment focusing" by Likens and Davis (1975) has been observed in other waterbodies
(Davis and Ford 1982). The potential magnitude of this effect appears to be predominately
related to mean basin slope (Blais and Kalff 1995).
Graphical analysis of sediment selenium and arsenic concentrations suggests that following
significant reservoir -wide reductions from 1985 to 2000, concentrations have become
relatively stable in the last 15+ years (Figures 2-75 through 2-78). While deep (> 25 m)
sediment selenium concentrations are substantially reduced from those measured decades
earlier, as was true for arsenic, profundal sediment concentrations clearly remain the most
elevated in the system. Low sediment selenium concentrations at the uplake site (Location
405.0) are typical of "background" or unimpacted locations and have remained virtually
unchanged over time.
With the exception of the deepest profundal sediments (> 25 meters deep; Location 422.0),
over the years sediment trace element concentrations in the main body of Belews Reservoir
(particularly Location 417.1 and to a slightly less extent, Location 417.2) have been reduced
to a similar magnitude as observed uplake (Location 405.0). The similarity of downlake
littoral concentrations with uplake sediment results, coupled with the lack of a diminishing
trend in recent years for these sites, suggest that a relatively static level of "near background"
concentrations has been achieved reservoir -wide in the shallow zones. Given the overall
absence of decreasing trends in recent years, future reductions in Belews Reservoir sediment
2-10

trace element concentrations should be anticipated to occur very gradually (i.e., over a scale
of decades).
Correspondingly greater trace element concentrations measured at the deepest site also
appear to have stabilized over the past decade. Due to the relatively low productivity and
resultant low accumulation rate of organic sediment deposition in Belews Reservoir, higher
concentrations of selenium and arsenic in the deepest reservoir sediments are anticipated to
also remain unchanged in the near term. Fortunately, however, maximum concentrations still
found in the spatially limited deep zone represent a relatively minor fraction, and less
important component, of the reservoir habitat for potential Belews Reservoir receptor
organisms.
2-11

SUMMARY
Belews Reservoir water quality has improved measurably since the mid-1980s in relation to
the original selenium -induced biological population collapse and resulting diversion of ash
basin discharge from Belews Reservoir. Virtually all former ash sluice -related trace
elements have been removed from the water column with concentrations in Belews Reservoir
during 2011 — 2015 and once again were less than applicable state water quality standards,
action levels, and often less than current analytical reporting limits.
Water quality data from 2011 - 2015 indicate conditions in Belews Reservoir continue to be
amenable to the maintenance and propagation of a diverse warm water aquatic community
commensurate with the nutrients afforded by an oligotrophic waterbody. Belews Reservoir
nutrient concentrations continued to remain relatively low except for the uplake area of the
reservoir, where most nutrient inputs have occurred historically. The reservoir's thermal and
DO structure in 2011 - 2015, were again similar to years prior that have seen the continued
recovery of the Belews Reservoir fishery.
Minor and gradual increases reported in recent years (Duke Energy 2011) for Belews
Reservoir pH, specific conductance, alkalinity, and major dissolved ionic constituents (i.e.,
calcium, magnesium, chloride, and to slightly lesser extent, sodium, potassium, and silica)
were not as evident in 2011 - 2015. The minimal, or lack of, increase was in part due to the
relatively normal rainfall patterns and resulting inflows to Belews Reservoir as compared to
the drought conditions evident in recent prior years 1998 - 2002 and 2007 - 2008. These
increases, if continued in the future under drought conditions, are of no special significance
to the recovery of Belews Reservoir fishery.
Concentrations of arsenic and selenium in Belews Reservoir surficial fine sediments during
2011— 2015 were similar to levels reported since 2000. Arsenic and selenium concentrations
in the deeper sediments of Belews Reservoir remain elevated relative to the reference site.
However, monitoring in the past 15+ years indicates that sediment arsenic and selenium
concentrations found downlake are fairly stabilized. Additionally, concentrations of arsenic
and selenium, but particularly selenium concentrations found downlake in shallower littoral
areas (i.e., ideal warm water fish and spawning habitat), are very near the low magnitude of
concentrations long -observed in the relatively unaffected uplake area of the reservoir.

CHAPTER 3
MACROINVERTEBRATES
INTRODUCTION
A benthic macroinvertebrate and plankton monitoring program was implemented in 1984 to
monitor and quantify bioaccumulation of selenium in select benthic macroinvertebrates and
planktonic organisms in Belews Reservoir. This program was initiated as a result of
contamination caused by ash basin effluent from BCSS during the station's early operational
years. In 1985, the BCSS ash basin discharge was rerouted from Belews Reservoir to the Dan
River. Since that time, contaminant levels in macroinvertebrates and plankton have been used,
along with fish community, fish tissue contaminant levels, and Reservoir chemistry data, as
indicators of ecological recovery in the Reservoir. An additional aspect of the monitoring
program was implemented in 1991 and examined the density and diversity of selected Belews
Reservoir macroinvertebrates.

Water Quality
Beginning in 2005, in conjunction with each macroinvertebrate sampling event, water
temperature and dissolved oxygen (DO) were taken just above the sediment at each location
using a pre -calibrated YSI Model 55 handheld DO meter. Starting in 2008, DO values were
measured in situ using a pre -calibrated Hach®HQ40d water quality meter.
Benthic Density and Diversity Monitoring
Benthic macroinvertebrate sampling in Belews Reservoir was conducted annually in July of each
year from 2011 — 2015. Samples were collected from three locations in Belews Reservoir:
Location 405.1 (uplake); Location 410.2 (downlake near the BCSS condenser cooling water
discharge canal); and Location 418.1 (downlake in the vicinity of the old BCSS ash basin
discharge, Table 1-1 and Figure 1-1). A Ponar dredge was used to collect five replicate bottom
3-1

samples from each location. Samples were collected from two to three meters to bracket the
depth of peak benthic abundance (Brinkhurst 1974). Samples were washed in a 500-µm mesh
sieve, the retained material placed into jars, preserved individually with 70% ethanol containing
rose bengal stain, and returned to the laboratory for analyses. Substrate characterization at each
sampling location was based on visual assessment during the sieving process. Organisms were
sorted in the laboratory and identified to the lowest practical taxon"'.
Macroinvertebrate densities (organisms per square meter of bottom area) were calculated
proportionally from the mean of the five replicate Ponar grab samples at each site. An
assessment of the balanced and indigenous nature of the benthic community was determined by
comparing macroinvertebrate densities and taxa abundance among the three sampling locations
and with historical data.
At the request of NCDENR, Duke Energy began spring monitoring of Hexagenia populations at
locations on Belews Reservoir in 2012 and continued that monitoring through 2015. Monitoring
was conducted in March or April at the same sampling locations listed above. Five replicates
were collected with a Ponar dredge and preserved in 70 % ethanol with rose bengal stain. All
Hexagenia were counted in each replicate and numbers among the five replicates were averaged
to give a density in No ./M2 for each location.
Selenium Monitoring
Benthic macroinvertebrates (Corbicula and Diptera) were collected once each year in May,
while plankton samples were collected each year in September for trace element analyses.
Samples were collected from three locations in Belews Reservoir: Locations 405.0, 418.0, and
419.3 (Table 1-1 and Figure 1-1). Benthic macroinvertebrate samples were collected with a
1,000-µm mesh kick net at wadeable depths along the shoreline at each location. Sample sorting
was performed in the field. Individual organisms (Corbicula and Diptera) were removed from
the sample detritus, grouped as described above in containers, preserved on ice, and returned to
the laboratory. Plankton samples (consisting of both phytoplankton and zooplankton) were
collected at each location using an 80-µm mesh plankton net. The net was allowed to sink to a
depth of three to five meters, pulled to the surface, and towed slowly behind a boat until a
plankton sample of sufficient volume was collected. Collected plankton were sieved and blotted,
'From 2001 through 2015 oligochaetes were identified to the lowest possible taxa, whereas in
prior years they had been only identified to order (Oligochaeta).

placed in containers on ice, and transported back to the laboratory. Until 2013, all samples were
frozen upon return to the laboratory and remained frozen until their delivery to the Nuclear
Services Laboratory at North Carolina State University where they were analyzed for selenium
content by neutron activation analysis (NAA). Starting in 2014, whole organism composite
samples representing two replicates, whenever possible, were sent to Duke Energy's
Environmental Sciences laboratory at New Hill, NC for trace element analysis to determine
concentrations (gg/g dry weight) of selenium in selected macroinvertebrate target groups
collected in the summer (reference Procedure NR 00107). Selenium concentrations in target
organisms were expressed as gg/g wet weight. Selenium bioconcentration data were analyzed
graphically by taxon and region.
RESULTS AND DISCUSSION
Substrate
Substrate composition was typically similar at all three locations and was comprised primarily of
varying proportions of silt, sand and organic matter (Table 3-1). Silt was the primary constituent
on most sampling dates at Locations 405.1 and 410.2, while organic matter was most commonly
predominant at Location 418.1. Substrate characteristics may influence benthic
macroinvertebrate density and diversity, but with the similarities observed among sampling
locations, substantial differences in benthic taxa diversity and density among sites attributable to
substrate variation would not be expected.
Water Quality
Water temperatures observed during sampling from 2011 — 2015 ranged from 27.9 to 34.1 °C
(Table 3-2). The lowest temperature each year occurred at Location 405.1, while maximum
temperatures were observed at Location 410.2, just below the BCSS discharge.
The DO concentrations observed from 2011 — 2015 ranged from 6.67 to 7.90 mg/L (Table 3-2).
The highest DOs were most often recorded at Location 405.1, while the lowest concentrations
were typically observed at Location 410.2.
Benthic Diversity and Density Monitoring
3-3

Benthic taxa abundance from 2011 - 2015 varied by year and location. Taxa numbers appeared
slightly less variable than density data (Tables 3-3 through 3-5 and Figure 3-1). Numbers ranged
from 17 at Location 405.1 in 2011 to 37 at Location 418.1 in 2012 (Tables 3-3 through 3-5 and
Figure 3-1). No clear patterns in taxa abundance were evident from year to year at Locations
410.2 and 418.1. At Location 405.1, taxa abundance increased each year from the five-year
minimum in 2011 to the five-year maximum in 2015 (Table 3-3 and Figure 3-1). At Locations
410.2 and 418.1 taxa numbers showed annual variations each year with the five-year maxima
observed in 2013 and 2012, respectively (Tables 3-4 and 3-5 and Figure 3-1). The highest
numbers of taxa among locations were observed at Location 405.1 from 2013 through 2015,
while maxima were observed at Location 418.1 in 2011 and 2012. During the previous five-year
study, total taxa numbers ranged from 21 to 39, thus indicating that overall taxa abundance
during 2011- 2015 was somewhat lower than during the last five-year period.
Macroinvertebrate densities varied among replicates from 2011- 2015 and mean densities varied
among years and locations. Mean annual densities ranged from 1,325/m2 in 2013 at Location
418.1 to 13,457/m2 in 2011 at Location 410.2 (Table 3-3 and Figure 3-2).
Graphical presentation of the last ten years of reported data indicated that mean
macroinvertebrate densities were variable and exhibited no clear trends (Figure 3-1).
Additionally, variability among replicates was as much as 100%. This type of variability is often
common among macroinvertebrate communities in lakes and reservoirs (Duke Energy 2009a,
2010).
Comparisons of year to year densities from 2011 - 2015 revealed that the highest mean annual
density from Location 405.1 (10,6097/m3) occurred in 2013, while maximum values at Locations
410.2 (13,457/m3) and 418.1 (10,071/m) were observed in 2011 (Tables 3-3 through 3-5 and
Figure 3-2). Spatially, densities were highest at Location 405.1 in 2012 and 2013, while
Location 410.2 demonstrated the maximum in 2011. Mean macroinvertebrate densities from
2011 - 2015 most often appeared to be higher than during the previous five-year period. Several
exceptionally high mean annual densities were reported: specifically at Location 405.1 in 2013,
and Locations 410.2 and 418.1 in 2011. These mean annual densities were higher than any
reported from these locations since 1991 (Duke Power Company 1996, 2001; Duke Energy
2006, 2011). The record high annual density at Location 405.1 in 2013 was comprised of a very
high number of nematodes, while Locations 410.2 and 418.1 in 2011 had exceptionally high
numbers of Diptera (Tables 3-3 through 3-5 and Figures 3-3 through 3-5). The causative factors
of these high densities and specific compositions is not known.
3-4

Since the substrate at the three Belews Reservoir regions are somewhat similar and past water
chemistry and chlorophyll data (Duke Energy 2006, 2011) show greater concentrations of major
nutrients and chlorophyll uplake versus downlake, the uplake location (405.1) might be expected
to support higher benthic macroinvertebrate densities than the downlake locations (410.2, 418.1).
Although Location 405.1 exhibited maximum spatial densities during four of the past five years,
macroinvertebrate densities in Belews Reservoir have most frequently exhibited no clear spatial
trend from the uplake region (more nutrients) to the oligotrophic downlake regions (Duke
Energy 2011).
During 2011 — 2015, macroinvertebrate samples were comprised primarily of Oligochaeta and
Diptera at all locations. "Others" (primarily nematodes) were dominant at Location 405.1 in
2013 and constituted high proportions of macroinvertebrate densities at Locations 410.2 and
418.1 in 2011 (Tables 3-3 through 3-5 and Figures 3-3 through 3-5). Comparatively high
numbers of Corbicula were observed at Location 410.2 in 2013 and Location 418.1 in 2011.
Annual mean densities for these groups of organisms varied from year to year, but oligochaetes
and dipterans collectively generally dominated collections at all three locations each year.
During years prior to 2001, oligochaetes were only identified to Order Oligochaeta. After 2001,
oligochaetes were identified to the lowest practicable taxon. Collectively, for the five years 2011
— 2015, the numbers of oligochaete taxa identified by location were: Location 405.1 - 14 taxa,
Location 410.2 - 11 taxa, and Location 418.1 - 12 taxa (Tables 3-3 through 3-5).
Hexagenia
Spring Hexagenia were typically found in comparatively low numbers from 2012 — 2015.
Numbers ranged from 0/m2 at Location 418.1 in 2012 to 809/m2 at Location 405.1 in 2015
(Figure 3-6). This represented variability consistent with total densities in Belews Reservoir, as
in most reservoirs. The annual average number of spring Hexagenia was highest in 2015 and
lowest in 2012. Spatially, Location 405.1 consistently yielded the highest numbers of spring
Hexagenia. A comparison of summer and spring Hexagenia populations at Belews Reservoir
locations showed that average summer densities were higher than spring densities at Locations
418.1 and 410.2, while spring densities at Location 405.1 were consistently higher than those of
the summer periods. This type of distribution clearly showed the considerable variability of both
spring and summer Hexagenia populations.
Selenium Monitoring
3-5

Selenium detection limits varied from year to year, as well as among sample organisms within a
given year. During 2001 — 2005, analyses of the Diptera had been hampered by collections of
smaller than optimal biomass, resulting in numerous elevated NAA detection limits (Figure 3-7
and Duke Energy 2006a). Extremely small sample biomass can lead to magnified errors due to
analytical interferences (including interferences from not -targeted elements) and result in
elevated detection limits (Scott Lassell, Manager of Nuclear Services, North Carolina State
University, personal communication). During the 2006 — 2010 reporting period, 16 of 102
sample results from analyses of Corbicula, Diptera, and plankton were reported below detection.
Of these, 14 were Diptera samples with two being composed of Corbicula. This was much
lower than during the previous report period when 52 dipteran samples were reported below
detection (Duke Energy 2011). During the 2011 — 2015 reporting period no samples were below
detection limits; however, at Location 405, insufficient biomass of Diptera and Corbicula were
collected to get analytical results (Figures 3-7 and 3-8).
Whole organism selenium concentrations in macroinvertebrates from the three locations in
Belews Reservoir from 2011 — 2015 most often continued to indicate similar or slightly variable
concentrations compared to previously reported data (Figures 3-7 through 3-9). Based on data
from 1985 to 2004, recent selenium levels appear to have dropped to near background levels.
Comparable to historical trends, organisms collected from Location 405.0 generally had the
lowest selenium concentrations. Macroinvertebrate selenium concentrations from the Diptera
and Corbicula at all locations showed little variability over the past five years as compared to
previous data and concentrations at all locations were in the mid to low historical ranges. During
2012 and 2013, Corbicula showed slight increases at Locations 405.0 (2013) and 419.3 (2012 —
2013). Dipterans showed a slight increase in selenium concentrations at Location 419.3 in 2012
and 2013, and at Location 418.0 during 2011— 2013 (Figures 3-7 through 3-9).
Selenium concentrations in plankton during 2011 — 2015 showed some similar spatial trends as
Corbicula and Diptera with higher concentrations at Locations 418.0 and 419.3 compared to
Location 405 (Figure 3-9). At Location 405.0, concentrations remained very low, while a sharp
increase was noted among plankton at Location 419.3 in 2012. At Location 418.0, a less notable
increase was also observed in 2012. Compared to 2006 — 2010, overall selenium concentrations
in plankton were generally similar.

Belews Reservoir continues to support a diverse macroinvertebrate community Reservoir -wide.
Taxa numbers were somewhat lower during 2011 — 2015 than during the previous five-year
period, but were within historical ranges. No clear spatial patterns in taxa abundance were
evident; however, taxa numbers during 2011 — 2015 were somewhat lower than during the
previous five-year period. Total numbers of taxa at Location 405.1 showed annual increases
from 2011 through 2015, while annual taxa numbers at Locations 410.2 and 418.1 varied from
year to year. Benthic macroinvertebrate densities demonstrated typical spatial and temporal
variability. Mean annual densities during 2011 — 2015 were most often higher than during the
previous five-year period and several exceptionally high mean densities were reported. All three
locations periodically demonstrated higher densities than any recorded at these locations since
1991. Notably high numbers of nematodes (Location 405.1) and dipterans (Locations 410.2 and
418.1) were reported. Macroinvertebrates were comprised primarily of Oligochaeta and Diptera
at all locations. "Others", primarily Nematoda, were dominant at Location 405.1 in 2013 and
constituted high proportions of densities at other locations. Corbicula were occasionally
abundant. Low numbers of Hexagenia were observed during both spring and summer sampling
periods.
Selenium concentrations in Belews Reservoir macroinvertebrates during 2011 — 2015 continued
to indicate low concentrations and variability when compared to results reported much earlier in
the study. This would appear to indicate that current levels are at near background
concentrations. Comparable to historical trends, macroinvertebrates and plankton collected from
Location 405.0 generally had lower selenium concentrations than other locations likely due to its
being the far afield from the initial ash basin discharge. Selenium concentrations in
macroinvertebrates and plankton from Locations 418.0 and 419.3 showed similar trends, with
some fluctuations in the low range during 2011 —2015. The results of this ongoing monitoring
program indicate that legacy selenium concentrations in the lentic food web continue to decline
or remain stable over time, and that the operation of BCSS is not having a detrimental impact on
the macroinvertebrate community of Belews Reservoir.

CHAPTER 4
FISH
INTRODUCTION
The North Carolina Wildlife Resources Commission (NCWRC) and Duke Energy have
monitored the fish community in Belews Reservoir since 1972. From 1972 through 1994,
taxa diversity and relative abundance were estimated using cove rotenone surveys (Van Horn
1978; Barwick and Harrell 1997). This monitoring was related to a significant decline in fish
populations attributed to selenium contamination from the Belews Creek Steam Station
(BCSS) ash basin from 1976 through 1985 (Cumbie and Van Horn 1978; Olmsted et al.
1986). Once selenium inputs into the reservoir were eliminated, trace element concentrations
in fish tissue gradually declined and the fish community slowly recovered (Barwick and
Harrell 1997). Due to this recovery and its associated sport -fish potential, the NCWRC and
Duke Energy decided to alter sampling methodology in Belews Reservoir to collect data that
were more specific to fish management objectives (and phase out the use of toxicants to
sample fish). Thus, spring electrofishing surveys of the reservoir were initiated in 1994,
along with a final cove rotenone survey (Duke Power Company 1996). Routine annual
monitoring of trace elements in the muscle tissue of multiple fish species was initiated in
1994 with the advent of the spring electrofishing program.
This chapter summarizes diversity and relative abundance of littoral fish and selenium
concentrations in fish muscle tissue from 1994 through 2015. Collection, analysis, and
reporting of contaminant concentrations in fish muscle tissue from the Dan River (receiving
water from the rerouted BCSS ash basin discharge) are reported annually elsewhere (Duke
Power 2001a, 2002, 2003, 2004, and 2005; Duke Energy 2006b, 2007, 2008, 2009b, 2010a,
2011, 2012, 2013, 2014).

MATERIALS AND METHODS
Spring Electrofishing Survey
Electrofishing surveys were conducted in Belews Reservoir in March or April, 2011 — 2015.
Five 300-m shoreline transects, identical to transects historically surveyed since 1994, were
surveyed at four regions (Figure 1-1): uplake above the Highway 158 bridge in the vicinity of
Location 405.0, midlake between the Highway 65 and 158 bridges in the vicinity of Location
419.2, discharge below Highway 65 in the vicinity of the BCSS thermal discharge and
Location 410.2, and downlake in the vicinity of the former BCSS ash basin discharge to
Belews Reservoir and Location 418.1. Between 2011 and 2013 all four regions were
sampled. Because the Uplake and Midlake regions were very similar in habitat, productivity,
and fish metrics (i.e., species composition and biomass) only three of the regions (Midlake,
Discharge, and Downlake) were sampled in 2014 and 2015. Transects included habitats
representative of those found in Belews Reservoir. Shallow flats where the boat could not
access within 3 to 4 in of the shoreline were excluded.
All sampling was conducted during daylight, when water temperatures were expected to be
between 15 and 20 °C. Surface water temperature (°C) was measured with a calibrated
thermistor at each transect. Stunned fish were collected by two netters and identified to
species. Fish were enumerated and weighed in aggregate by taxon, except for black basses,
where total length (mm) and weight (g) were obtained for each individual collected. Catch
per unit effort (number of individuals/1,500 m) and the number of species were calculated for
each region. Condition (Wr) based on relative weight was calculated for Largemouth Bass
Micropterus salmoides >150 mm long, using the formula Wr = (W/WS) x 100, where W =
weight of the individual fish (g) and Ws = length -specific mean weight (g) for a fish as
predicted by a weight -length equation for that species (Neumann et. al. 2012). Condition
was compared among years and among regions with analysis of covariance (ANCOVA, a =
0.05) and Tukey's pairwise comparison (Analytical Software 2008; SAS 2010).
Selenium Monitoring
Selenium concentrations were measured in skeletal muscle tissue of Redear Sunfish Lepomis
microlophus and Largemouth Bass collected during spring electrofishing at each of four
locations, listed from midlake to downlake: 419.4, 419.1, 410.2, and 418.1 (Figure 1-1).
Uplake collections at 419.4 were discontinued in 2014 because of similarity to the other
4-2

uplake area 419. 1. Following the standard operating procedures for fish tissue assessments
(NCDENR 2013b), three composite samples (each with three individuals) in 2011, 2012, and
2013 were collected per species at each location such that the total length of the shortest fish
was >75% of the total length of the longest fish within each composite. In 2014 and 2015,
the same collection procedures above were followed, except for that six fish per species per
site were collected. Fish were placed in labeled polyethylene bags and remained on ice until
returned to the lab. Once at the lab, they were frozen until processed.
Epaxial muscle tissue was extracted from each fish within each composite and placed in an
acid -washed polyethylene vial. From 2011 to 2013, Selenium concentration (µg/g, wet
weight) was determined from composite samples by neutron activation analysis at the North
Carolina State University Nuclear Services Laboratory in Raleigh, NC. From 2014 to 2015,
individual fish tissue samples were sent to the Duke Energy's Environmental Sciences
laboratory at New Hill, NC for trace elements analyses to determine concentrations (µg/g,
dry weight) of selenium. Graphical methods were used to examine temporal and spatial
trends of selenium concentration in fish skeletal muscle.
RESULTS AND DISCUSSION
Spring Electrofishin Survey
Potential effects of BCSS on Belews Reservoir fish populations were assessed through
annual spring surveys during March or April, 2011 — 2015. A diverse fish community was
present from 2011 to 2015 representing 22 species (excluding two hybrid centrarchid
species) and 8 families, totaling 16,677 individuals (Tables 4-1 and 4-2). Sunfishes
(Centrarchidae = 77.8%), shad (Clupeidae = 11.70/o), and minnows (Cyprinidae = 5.6%)
numerically dominated catches. The remaining fish families each contributed less than 4%
of the total catch as follows: temperate bass (Moronidae = 1.2%), catfish (Ictaluridae =
1.1%), darters and perch (Percidae = 2.7%), and livebearers (Poeciliidae 0.01%). A total of
1,267 kg of fish were collected, primarily consisting of minnows (41.0%) and sunfishes
(47.2%) (Table 4-3). Catfishes contributed 7.6%, while the remaining fish families each
contributed less than 5% of the total biomass as follows: shad (3.4%), temperate bass (1.0%),
darters and perch (0.6%), and livebearers (< 0.01%). Alewife Alosa pseudoharengus and
Spotted bass Micropterus punctulatus were collected for the first time during the 2011 to
4-3

2015 fish surveys. No threatened or endangered species have been collected during the
studies.
Mean numbers of fish/1,500 in collected in March or April (2011 — 2015) varied with the
highest value observed at the uplake region (2,3 18), intermediate at the midlake (1,135), and
downlake (549) regions, and lowest at the discharge (356) region (Figures 4-1). Mean
biomass (kg) of fish/1,500 in collected in March or April (2011 — 2015) varied with the
highest value observed at the uplake region (219.2), intermediate at the midlake (64.6) and
discharge (32.3) regions, and lowest at the downlake region (25.1) (Figure 4-2). Mean
number of species of fish/1,500 in collected in March or April (2011 — 2015) varied with the
highest mean value observed at the uplake region (15), intermediate at the midlake (14) and
lowest at the downlake (9) and discharge (9) region (Figure 4-3). Fish community metrics
were similar at the discharge and downlake regions principally due to BCSS pumping
maintaining a circulation pattern within the epilimnion of the two regions (Chapter 1).
Data were generally similar to those collected during past study periods (Duke Power
Company 1996; Duke Power 2001a; Duke Energy 2006a; Duke Energy 2011). A total of 32
species and two hybrid centrarchid species have been recorded from electrofishing surveys in
Belews Reservoir since 1994 (Table 4-1). Variation in the abundance of individual species
has long been noted (Van Horn 1978; Duke Power Company 1996; Barwick and Harrell
1997; Duke Power 2001b; Duke Energy 2006a; Duke Energy 2011). Analysis of Belews
Reservoir fish collected by Duke Energy since 1994 (77,082 individuals captured from 1994
to 2015) indicates that the three most abundant species are Bluegill Lepomis macrochirus
(51.60/o), Threadfin Shad Dorosoma petenense (11.7%), and Redbreast Sunfish Lepomis
auritus (8.7%). Multiple species (n = 23) constituted less than 1.0% of the total number
collected from 1994 to 2015. Once the fish population recovered from selenium
contamination, Bluegill were gravimetrically dominant in rotenone surveys from 1991 to
1994 (Barwick and Harrell 1997). Bluegill were also numerically dominant from trammel
net and electrofishing surveys from 1974 to 1976 (Van Horn 1978), and in electrofishing
surveys since 1994 (Duke Power Company 1996; Duke Power 2001a; Duke Energy 2006a,
2011).
Largemouth Bass condition by year (1994 — 2015) differed significantly (P < 0.0001) with
Wr means ranging from 79.8 (1994) to 92.7 (2006) (Figure 4-4). Relative weight means were
between 80.0 and 90.0 in most years, 1994 —1995 and 2004 — 2006 were similarly low (79.7-
79.3) and high (91.0 — 92.7), respectively. Largemouth Bass condition by region also

differed significantly (P < 0.0001) with means ranging from 81.4 (discharge) to 87.9 (uplake)
(Figure 4-5). Although statistically significant, the mean largemouth bass Wr between
regions (between 80 and 90) suggest that on average, largemouth bass throughout Belews
Reservoir generally exhibit the same body condition.
In addition to Largemouth Bass, condition values, the number, biomass, and number of
species of fish were generally higher uplake relative to downlake. Similar uplake-to-
downlake differences were observed for nutrient concentrations of total nitrogen (Figure 2-
64), total phosphorus (Figure 2-66), total organic carbon (Figure 2-67), and total suspended
solids (Figure 2-69). These data are consistent with the greater productivity observed uplake
relative to downlake, which is more oligotrophic.
The observed spatial heterogeneity in fish community metrics in Belews Reservoir is similar
to that of other Piedmont reservoirs in North and South Carolina (Duke Energy 2009a,
2010b) and supports the spatial heterogeneity noted by Siler et al. (1986). The authors
reported that the number and biomass of fish were higher uplake than downlake due to higher
levels of nutrients and resulting higher productivity uplake versus downlake. Other factors
that shape the longitudinal heterogeneity pattern (from uplake to downlake) in fish
communities in reservoirs are increasing reservoir depth, changing physical habitat,
increasing amount of open water, increasing wind exposure, and different species preferences
to these patterns (Gido et al 2002).
Selenium Monitoring
Annual mean selenium concentrations in the muscle tissue of Redear Sunfish (2011 — 2015)
and Largemouth Bass (2011 — 2015) collected from Belews Reservoir ranged from 0.83 to
2.96 µg/g (wet weight) and from 0.92 to 2.73 µg/g, respectively (Figures 4-6 and 4-7). Mean
selenium concentrations in Redear Sunfish and Largemouth bass were typically lower at
locations furthest from the former ash basin discharge (419.4 or 419.1) and highest at
locations influenced by the operations of the former ash basin discharge during the early
years of BCSS (410.2 or 418.1).
Mean selenium concentrations in Redear Sunfish have declined at areas sampled since 1995
and remained consistent in Largemouth Bass since 2007. Concentrations are below levels
considered detrimental to fish reproduction (Cumbie and Van Horn 1978; Gillespie and

SUMMARY
Fish survey metrics associated with species composition, catch (number of individuals and
species/1,500m), and fish heath (Wr's and Se concentrations) represent a self-sustaining
balanced and indigenous fish community in Belews Reservoir (2011 — 2015), consistent with
previous data since 1994. A total of 22 species, two centrarchid hybrid species, and seven
families, dominated by sunfish (Centrarchidae) were collected from 2011-2015. Two new
species were collected since 2011. The fish metrics represent sufficient food web organisms
and are similar to that of other Piedmont reservoirs in North and South Carolina (Duke
Energy 2009a, 2010b)
The spatial heterogeneity of Belews Reservoir water quality and fish community metrics is
similar to that noted by Siler et al. (1986). Uplake and midlake regions had the highest fish
species diversity and catch, likely due to higher relative concentrations of phosphorous,
organic carbon, and total suspended solids from watershed inputs (Chapter 2). Conversely,
discharge and downlake regions had the lowest fish species diversity and catch, reflective of
oligotrophic conditions.
Mean selenium concentrations in Redear Sunfish and Largemouth Bass remained below
levels considered detrimental to fish reproduction (Cumbie and Van Horn 1978; Gillespie
and Baumann 1986) and well below the 10-µg/g, wet weight, concentration considered safe
for human consumption (NCDHH 2007). Belews Reservoir continues to maintain multiple
trophic levels of fish, including necessary food web organisms, for a self-sustaining balanced
and indigenous fish population.

Duke Energy — Belews Creek Steam Station
Subject NPDES Renewal Support—Ash Basin Capacity
Devin Secore, EIT
From R. Kula Kulasingam, PhD., PE
Date August 17, 2016
Dear Ms. Dishmon, .
Duke Energy (Duke) requested AECOM to assist in supporting the NPDES Permit renewal for the
Belews Creek Steam Station by performing available free water volume estimates for the Active
Ash Basin (ash basin). The current NPDES Permit has a requirement at all times a free water volume
(FWV) equivalent to the sum of the maximum 24-hour plant discharges plus all stormwater to the
pond resulting from a 10 -year, 24-hour storm, when using a runoff coefficient of 1.0, be maintained.
This report includes required calculations to demonstrate there will be sufficient FWV capacity in
the ash basin for ash volume and stormwater runoff for the next 5 years at a water surface
elevation of 749.0 ft, which is the lowest water elevation the ash basin currently operates at. To
calculate the FWV capacity of the ash basin, Duke provided AECOM with yearly and monthly ash
tonnage deposited into the ash basin from 2011- July 2016. AECOM converted this tonnage to
volume using a density of 55 lbs per cubic foot, which is the density used in the previous NPDES
permit renewal provided by Duke. Duke also provided the 24-hour plant discharge volume in the
dry weather detention of a maximum of 17.9 MGD. Duke added 10% to this flow and converted to
acre-feet to get an estimated 24-hour discharge volume of 60.42 acre-feet.
The 10 -year, 24-hour stormwater runoff volume is calculated by multiplying the ash basin drainage
area of 742.6 acres, used in the previous NPDES update, by the 10 -year, 24-hour rainfall depth of
5.1 inches. This yields a total stormater runoff of 324.91 acre-feet. The total required FWV was
calculated as the sum of the maximum 24-hour plant discharge volume and the 10 -year, 24-hour
runoff volume, to equal 385.33 acre-feet.
The water volume was calculated as 2,972 acre-feet by comparing the 2014 bathymetric surface to
a water surface at elevation 749.0 ft in AutoCAD Civil 3D . Figure 1 attached provides this
comparison by showing the depth of water in the ash pond.

AECOM
The table below shows the actual and estimated volume consumed by ash deposited from 2014
through 2021. The reason AECOM chose to start at 2014 was because that is the year when the
latest bathymetry was provided. Using data provided by Duke on ash consumption, AECOM was
able to estimate the total bottom ash, 730,940 tons, which will be sluiced to the ash basin by
December 2021. Fly ash is being handled dry and disposed in a landfill. AECOM understands the
FGD waste stream is handled separately in the FGD waste water treatment system. This treated
water is assumed to be included in the 17.9 MGD. The coal consumed was estimated from August
2016- December 2021 by averaging the previous years and adding 10% to be conservative.

Although there are uncertainties in the amount of ash produced/disposed in the ash basin, AECOM
believes based on the information provdued by Duke and the calculations presented herein, that
adequate FWV can be maintained at the Ash Basin at Belews Creek Steam Station till the end of
2021.

AECOM appreciates this opportunity to be of continued service to Duke Energy, and we ask that
you contact us at 704-522-0330 if you have any questions or require additional information.
