Permit Renewal Application
Dear Mr. Poupart:
Duke Energy Carolinas,LLC(herein after"Duke")requests the subject permit be renewed and reissued. The above
referenced permit expires on April 30,2017. This request for renewal is in addition to the currently pending request
for modification of the subject NPDES permit. As mandated by North Carolina Administrative Code 15A NCAC
2H.0105(e),this permit application is being submitted at least 180 days prior to expiration of the current permit.
Please find enclosed in triplicate,the renewal application,which includes the following items:
• EPA Form 1
• EPA Form 2C
• Site Map showing the location of all outfalls(internal and final)
• Waste Flow chart and description of waste flows through facility in accordance with EPA Form 2C Item II-
A(Attachment 1)
• Narrative description of sources of pollution and treatment technologies in accordance with EPA Form 2C
Item II-B(Attachment 2)
• List of Potential items not covered by analysis in accordance with EPA Form 2C Item VI(Attachment 3)
• Alternate Schedule Request for 316(b)(Attachment 4)
Condition A(11)of the current permit for the Dan River Combined Cycle Plant(DRCC)requires that Duke request
a continuation of its 316(a) variance beyond the term of the present permit. Enclosed is an EPA guidance letter
dated August 11, 1988 outlining the general procedure to be followed in requesting the continuance of a 316(a)
variance. The following is Duke Energy's response to the pertinent factors contained in the EPA general procedure
for the reissuance of the 316(a)variance:
1. The permittee must request the variance be continued.
Response: Duke hereby requests continuation of the 316(a)variance reflected in the reissued
Permit for the Dan River Combined Cycle Plant
2. Plant operating conditions and load factors are unchanged and are expected to remain so for the term of the
reissued permit.

NC0003468
Rockingham County
Response: The Combined Cycle plant 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 permittee's knowledge to the plant discharges or other discharges in the plant
area which could interact with thermal discharges.
Response: There have been no changes to the combined cycle plant discharges since the current
NPDES permit issuance in 2013.
4. There are no changes to permittee's knowledge to the biotic community of the receiving water body which
could impact the previous 316(a)determinations.
Response: As demonstrated by Duke's environmental monitoring,since issuance of the current
NPDES permit there have been no changes to the biotic community of Dan River
which would impact the previous 316(a)determinations.
Condition A(12)of the current permit requires that DRCC comply with the Cooling Tower Intake Structure Rule per
40 CFR 125.95. As allowed under§125.95(a)(2), Duke requests an alternate schedule for the submission of the
applicable 3 16(b)information for Dan River.
DRCC requests explicit coverage in permit to dewater the interstitial water in Ash Settling Basin through NPDES
Outfall 002.
DRCC is scheduled to replace the current oil and water separator(OWS). The current OWS discharges to a sump
designated as Outfall 001A prior to mixing with other low volume waste in the wastewater sump to be discharged to
Outfall 001 The new OWS will discharge to the makeup water tank for the Cooling Towers and then to Outfall 001.
The compliance sampling for the new OWS will be moved to an outlet on the discharge side of the OWS.
With reissuance, Duke requests the following modifications:
• Duke is requesting the removal of Condition A(9)of the current permit. Condition A(9)requires that there
be no discharge of plant waste to the pond unless the permittee to determine and report to the Division that
there is sufficient free water volume equivalent to the equivalent to the sum of the maximum 24-hour plant
discharges plus all direct rainfall and all runoff flows to the pond resulting form a 10-year,24-hour rainfall
event when using a coefficient of 1.0 before. Since the decommissioning of the coal-fired units in October
2012. DRCC no longer discharges ash transport water,and there is no risk of overfilling. As a result the
calculation is unnecessary.
• Duke is requesting a variance for Total Suspended Solids(TSS)at NPDES Outfall 001 to accommodate for
TSS concentrations in the intake water.
• Duke is requesting the reinstatement of Former NPDES Outfall 009. Former Outfall 009 has been
identified to have basin seepage (S-4) and stormwater runoff from the switchyard. The stormwater is
processed through an oil trap tank prior to discharge.
• Duke is requesting designation of Effluent Channels for Areas of Wetness (AOW)S-1, S-2 and S-3. This
request is based upon a site visit on June 8, 2016 by Sherri Knight and Shuying Wang from the Winston-
Salem Regional Office. S-1 is an effluent channel discharging directly to Railroad Branch. Duke is
requesting a waiver from sampling requirements for S-1 based upon the access to this area, which is
precarious at best.
• Duke is requesting addition of Effluent Channels for AOWs, S-2 and S-3. These AOWs are defined
channels that stretch from outside the ash basin to Railroad Branch. Duke is requesting the entirety of the
feature be designated as an effluent channel. Duke is requesting waiver of sampling requirements for S-2
as it flows into S-3 prior to entering Railroad Branch.

• Duke has previously notified the Department of two other AOWs S-6 and S-7 which do not discharge to
waters of the state. Duke is not requesting that they be added at reissuance of the permit.These AOWs are
areas along the toe of the dike that intermittently appear damp. There is a significant floodplain lip
between this point and the river. There is no flow from this area to waters of the State. These AOWs were
reviewed by DEQ on June 8,2016. Duke requests confirmation that no permit coverage is needed for these
areas.
Duke requests notification that this application is complete.

RE: 316 Q 4dance for Permit Reissuance
Dear r ldefi n:
ens have arisen as to what procedures and activities are necessary in
ng a permit for .a facility which has thermal limitations based on a
previous variance granted under Section 316(a) of the Clean water Act. The
following is provided as a follow-up to information provided at the February
1988, E'A/State meeting in Destin, Florida.
A thermal variance granted under S316(a) terminates on expiration of the NPDES
permit of which it is a part (Attachment A). Procedures for a reissuance are
virtually unchanged frau an initial determination. The amount of data necessary
to support the variance at the time of reissuance will probably be minimal.
tionBowever, if
qu conditions have changed materially, a significant ntity of informa-
maY needed.
NOTE: Tb the extent that permitter are unaware of these requirements,
should be notified of than expeditiously so that they can be prepared
The general procedure is as follows:
1. The permittee must request that the variance be continued, preferably at the
time of permit application. At that time, he should provide a basis for that
continuance. The basis could be as simple as: (a) plant operating conditions
and load factors are unchanged and are expected to remain so for the term of
the reissued permit, (b) there are no changes (to his knowledge)
discharges or other dischargesedge) interact ract
with the thermal discharges, in the plant site area which could
to the biotic cdisch roof , �receiving
are no changes (to his knowledge)
y ng water body which would imact the
previous 316 determinations.
2. If the permitting authority agrees with the basis, appropriate permit condi-
tions would be developed; otherwise, additional data would be requested as
needed. Request for additional data must be made within 60 days of receipt of
the application (Answer to Question 7, Attachment A). Additional studies can
be made a permit requirement if needed (Answer to Question 7).

Page 2
August 11, 1988
3. The Fact Sheet/Rationale should contain a summary of 316 variance activities
from the-previous permits (dates, determinations, limitations, etc. ) and an
indication of the pr6posed basis for continuing the 316 variance. Sample
language is included in Attachment 8.
4. The Public notice requirements are contained in S124.75(a).
is also included in Attachment B. Sample language

Introduction
The Dan River Combined Cycle (CC) Station, located in Rockingham County, North Carolina, consists of two
General Electric 7FA gas turbine generators with a General Electric D1 Steam Turbine. The nominal output for
this facility is 620 MW. Prior to October 2012, the plant operated three coal—fired generating units and three
Combustion Turbines. These units were retired once the CC block came online and are currently undergoing
demolition. The CC Station operates separately and independently from the retired coal Plant. However, some
auxiliary systems(water intake and NPDES Outfalls)are shared between the two plants.
The CC Station pumps water from the Dan River via 3 raw water pumps to the Graver clarifier. Water is withdrawn
from the Dan River, as required,. to makeup evaporative and blowdown losses. Coagulant(ferric sulfate), polymer
(flocculant), sodium hydroxide (pH control), and sodium hypochlorite (disinfection) are added to the raw water.
Water from the clarifier is further treated through gravity filters. Filtered water is stored in the Fire Water/Service
Water Tank(approximately 350,000 gallons) for fire protection, used as makeup water to the heat recovery steam
generator(HRSG), and/or various other plant functions and cooling tower basin(approximately 1 million gallons)
for makeup of condenser cooling water.
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. All plant waste streams are directly or indirectly
discharged to the Dan River or hauled off site for disposal. Each component of the discharges are described below.
Outfall 001—Combined Cvcle Power Block
Outfall 001 is the gravity flow discharge from the Combined Cycle Wastewater Sump (CCWS)to the Dan River.
Various wastewater streams combine in the CCWS prior to discharge. These flows consist of cooling tower
blowdown, oil and water separator discharge (Internal Outfall 001A), treated domestic sewage, Ultrafiltration
backwash, reverse osmosis (RO)/Portable demineralizer trailer rinse down, RO cleaning waste, and fire (service)
water/demineralizer tank overflow and drainage.
Cooling Tower Blowdown
Condenser cooling water(CCW) is supplied through filtered water sent to the ten cell cooling tower basin.
This water is recirculated and cycled with approximately 5% makeup added hourly to account for
blowdown and evaporation loss. Sodium hypochlorite is added to the CCW for disinfection/biological
growth control, a dispersant/corrosion inhibitor is added for water chemistry parameter monitoring on the
tower and corrosion inhibition,and a small amount of defaming agent is added to prevent foaming issues.
A blowdown stream averaging around 400 gpm is used to maintain concentration of total dissolved solids
in the cooling tower to within proper operating limits. Sodium bisulfite is added to the blowdown stream
prior to discharge into the CCWS for chlorine removal. During cooling tower maintenance, the cooling
tower basin may be drained to various levels, including emptied. Depending on the activity, the cooling
tower basin water may be partially or fully routed through the blowdown line for dechlorination or through
retention basins/tanks for dechlorination and discharge out Outfall 001.

Oil and Water Separator(Internal Outfall 001A)
All powerhouse building floor drains and all outside oil filled equipment drains are piped to an oil and
water separator(OWS). These waste streams include small quantities of chemicals used for process water
analyses and closed cooling water system. The closed cooling water system is approximately 21,000
gallons and contains propylene glycol as a coolant and a corrosion inhibitor. The powerhouse building
floor drains can receive input from spillage/leakage of various chemical and equipment, floor wash water,
and maintenance activities. The following are examples of materials that are stored/used inside the
powerhouse: ammonium hydroxide, hydrazine, propylene glycol, new/used lube oil, kerosene, diesel fuel,
phosphate, corrosion inhibitors, industrial cleaning products,and miscellaneous lab chemicals. The current
OWS discharges to Internal Outfall 001A collection sump prior to gravity flow to CCWS. Compliance
samples are collected from the Internal Outfall 00IA collection sump.
The current OWS will be replaced beginning in July 2016 with completion of the project projected for
October 2016. Upon completion, the new discharge of the new OWS will be to the cooling tower basin
and will be used in CCW makeup water. Compliance sampling location for Outfall 001A will be on the
discharge side of new OWS.
Treated Domestic Sewage
Sanitary wastes are treated by an aeration treatment package plant consisting of bar screen, aeration tank,
clarifier, chlorine contact chamber, and a sludge holding tank. After chlorination via sodium hypochlorite
tablets,treated water discharges to the CCWS.
UF Backwash Portable demineralizer trailer backwash and RO rinse water
During normal demineralized (demin) water demand periods, the RO system runs every 8 hours with a 4
hour break in-between. On initial startup the RO system has to rinse down to be in the optimum operating
conductivity range. The rinse water produced during this initial startup is discharged to the CCWS. When
the RO is operating,the UF system typically backwashes every 3040 minutes. This consists of about 135
gallons per minute (gpm) of backwash wastewater being discharged to the CCWS for approximately 2
minutes. During high demin water demand periods, portable demin trailers are brought in to supply
additional demineralized water. These trailer have to be rinsed in. Approximately 70 gpm of rinse water is
discharged to the CCWS during rinse in. When the portable demin trailer has been exhausted or is no
longer needed,the trailer is drained to the CCWS.
RO Cleaning Waste
The RO system is normally cleaned once a quarter. This cleaning consist of an acid cleaning, a caustic
cleaning,and treatment utilizing a biocide. The cleaning waste is sent to the neutralization tank and treated
with acid/caustic for pH control. Upon neutralization,the waste is discharged to the CCWS.
Service Water/Fire Water Storage Tank and Demineralizer Water Storage Tank Over/low/Drain
Periodically,maintenance will need to be performed on the Service Water/Fire Water Storage Tank and the
Demineralizer Water Tank. This maintenance will require the water from the storage tanks to be drained to
the CCWS. Service Water/Fire Water has been treated via clarification, filtration and addition of ferric
sulfate for coagulation, sodium hydroxide for pH control, sodium hypochlorite for disinfection, and
polymer for flocculation. Demineralized water is service Service Water/Fire Water that has undergone
ultrafiltration,reverse osmosis,and mixed bed demineralization.
HRSG Slowdown
HRSG makeup water is drawn directly from the Service Water/Fire Water tank. In addition to clarification
and filtration, HRSG makeup water undergoes ultrafiltration, reverse osmosis, and mixed bed

demineralization. UF uses citric acid and sodium hypochlorite. RO utilizes an antiscalant, sodium
hydroxide for pH control, and sodium bisulfate for dechlorination. HRSG makeup water is treated with
ammonium hydroxide for pH control, and oxygen scavenger, and phosphate for corrosion inhibition.
Water in the HRSG blowdown sump is pumped to the cooling tower basin to be used for CCW makeup
water. Other waste streams that flow to the HRSG blowdown sump via various drains throughout the
station:auxiliary boiler blowdown,Ultrafiltration(UF)acid cleaning and bleach cleaning waste and reverse
osmosis(RO)concentrate
Chiller Blowdown
The chiller system is utilized during the late spring and summer months to increase power output of the gas
turbines by cooling the incoming air. The chilled water, which is a 33% mixture of propylene glycol and
water has a system total capacity of approximately 65,000 gallons, is supplied by a chiller plant. The
warmed water exiting the cooling tower is returned to the chiller plant to be recycled and cooled. 2,000
gallons of refrigerant is utilized in the chiller plant system. The cooled water exiting the chiller system
consists of approximately 20,000 gallons of clarified and filtered water that is treated with sodium
hypochlorite for biological control and a dispersant/corrosion inhibitor added for water chemistry
parameter monitoring. The cooling water system side of the chiller tower has a blowdown stream(chiller
blowdown)of approximately 32 gpm that is utilized to maintain water chemistry within the tower at proper
operating limits and discharged into the cooling tower basin to be used in CCW makeup water. Prior to
the winter months, the cooling water side of the chiller system is laid up utilizing approximately 150
gallons of a sodium hydroxide based layup chemical which is pumped into the cooling water side of the
system consisting of approximately 20,000 gallons,circulated and drained to the cooling water tower basin.
Combined Cycle Industrial Wastes for Offsite Disposal
Clarifier Sludge
Sludge is removed from the clarifier via sludge pumps and sent through a thickener tank where additional
polymer is added. Once thickened,the sludge is sent through a plate and frame filter press for dewatering
and to an industrial landfill for disposal. Potentially,this material may be used for beneficial use in brick
making.
Gas Turbine Compressor Wash
Each combustion turbine unit is equipped with a 6,000 gallon compressor wash water sump. Periodically,
the combustion turbines receive an on line or off line compressor wash. This activity involves injecting
water with a mild detergent into the compressor section of the turbine and subsequent rinse cycles. The off
line wash generates approximately 4,000-5,000 gallons of waste water per turbine. This activity occurs
between 3-5 times per year per turbine. Wash water is pumped out by a certified third party waste disposal
company for offsite disposal
Chiller Sumps
The chiller plant has two chiller sumps, where chilled water(propylene glycol/water mixture)drains from
maintenance activities and normal operation. These sumps are monitored on a daily basis. Chiller sump is
pumped out by a certified third party waste disposal company for offsite disposal.
Outfall 002—Ash Basin
Coal-Fired Units
The coal-fired units were decommissioned in April 2012. Upon retirement of the coal fired units, waste
streams from processes which historically went to the ash basins are no longer generated. Waste

streams from closure activities may be sent to the secondary basin until April 2017. Per the Coal
Combustion Residual Regulation,all discharges to the basins must be re-routed by April 2017.
Stormwater Run0lf
The secondary ash basin accommodates stormwater flows from the yard drainage sump and basin
watershed area including the drainage area of the Dry Stacks (approximately 77 acres.). The average
stormwater run-off flows are based on 44 inches of rain per year with 100%run-off from the basin surfaces
and 50% run-off from other areas. The average run-off for the ash basin watershed area is 0.418 MGD.
The coal yard drainage drains to the yard drainage sump and is then pumped to the ash basin. The coal
yard has an average run-off of 0.007 MGD. This run-off is based on 44 inches of rain per year with 50%
run-off.
A filtration treatment skid will be installed at the yard drainage sump to remove Total Suspended Solids
(TSS)from the stormwater. The installation is scheduled to begin in July and completed by October
2016 Upon completion, the treated stormwater will be pumped to Outfall SW009 under Industrial
Stormwater Permit NCS000572.
Stormwater from the basin drainage area will be re-routed for collection and discharge to the City of
Eden under an Industrial User Permit #1013. The water re-direct project is scheduled to begin in
August 2016 andbe completed in February 2017.
Chemical Additions to the Ash Basin
Small volumes of aluminum sulfate (alum), ferric sulfate, and miscellaneous polymers are infrequently
added directly to the ash basin to encourage coagulation and flocculation, thus controlling suspended
solids. Sulfuric acid, sodium hydroxide and CO2 injection are used for pH control. Some ongoing
chemical additions may be required to manage waste streams from closure activities,including dewatering.
Dewatering
At the present time Duke Energy is expecting to discharge the wastewater generated from the removal of ash
(including dewatering of ash basins to allow excavation and dewatering of excavated ash prior to loading onto trucks
or rail cars) from the site through the current Outfall 002. It is anticipated that as dewatering proceeds some
additional treatment may be needed to meet permit discharge limits at Outfall 002.
Former Outfall 009
Area has been identified to have basin seepage and the switchyard stormwater runoff which is processed through an
oil trap tank that is discharged through this outfall. During the review of NPDES stormwater permit application
dated August 1, 2014, DEQ staff indicated that this outfall would be covered in the reissued NPDES wastewater
permit.

Attachment 4-Alternate Schedule Request§316(b)of the Clean Water Act
Dan River 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 Dan
River Steam Station 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;
— The facility has 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. The 316(b) application submittal timeframe for Dan River Steam Station is established under
§125.95(a)(2),which states:
"The owner or operator of a facility subject to this subpart whose currently effective
permit expires prior to or on July 14, 2018, may request the Director to establish an
alternate schedule for the submission of the information required in 40 CFR 122.21(r)
when applying for a subsequent permit..."
As allowed under §125.95(a)(2), Duke Energy requests an alternate schedule for the submission of
the applicable 316(b) information for Dan River. Per§122.21(r)(1)(ii), the following information must be
submitted for all existing facilities:
§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
The actual intake flow (AIF), as well as the design intake flow (DIF), for Dan River Steam Station is less
than 125 million gallons per day (MGD); therefore, the additional information requirements under
§122.21(r)(1)(ii)(B) Existing facilities greater than 125 MGD AIF are not applicable to Dan River Steam
Station.

In the preamble to the rule, EPA states "... for many facilities, it may take as long as 39 months to
plan, collect, compile the date and studies required to be submitted with the permit application.." and
further states"This timeframe will be adequate for facilities under 125 MGD." Duke Energy,therefore,
requests the 316(b) information for Dan River Steam Station to be submitted on or before December 27,
2017(i.e. 39 months from the effective date of the rule).
Even though the station was subject to the remanded Phase II 316(b) Rule and prepared draft
documents as required by the remanded rule, significant changes were made between the remanded
Phase II Rule and the recently finalized 316(b) rule. In addition,significant modifications to the operation
of the station have occurred since the remanded Phase II Rule. An alternate schedule, therefore, is
justified. A summary of the changes are as follows:
— Information requested in §122.21(r)(2), (3), and (5)was required under the remanded rule;
however, these documents were not finalized due to the timing of the court ruling. In
addition, the operations at Dan River Steam Station have substantially changed since the
remanded rule. Units 1-3 have retired= and the generation was replaced with a 637 MW
combined-cycle unit with closed-cycle cooling.
— Additional Information is requested in §122.21(r)(4) that was not requested in the
remanded rule.The additional information includes:
o Identification of protective measures and stabilization activities that have been
implemented, and a description of how these measures and activities affected the
baseline water condition in the vicinity of the intake; and
o A list of fragile species at the facility.
— Information requested in §122.21(r)(6) – r(8) is new and data must be compiled and
evaluated to complete these submittals.
Duke Energy is not planning on collecting any new biological data on the source water, or
conducting impingement or entrainment studies at the cooling water intake structure and has not been
asked to do so by North Carolina Department of Environmental Quality(NCDEQ). Existing biological data
will be used to complete §122.21(r)(2) Source Water Physical Data and §122.21(r)(4) Source Water
Baseline Biological Characterization Data. Furthermore, with the station utilizing a closed-loop
recirculating system, a design through-screen velocity of less than 0.5 feet per second (fps), and a DIF of
less than 12 MGD, which equates to a small percentage of the annual mean flow of the Dan River, Duke
Energy intends to demonstrate the existing technologies at Dan River Steam Station meet the best
technology available (BTA)standard for both impingement and entrainment mortality.
1 Refer to Fed. Reg.Vol.29.No. 158,dated August 15,2014,p.48359
Units 1 and 2 were retired prior to the remanded Phase II 316(b)Rule.
