316 (a) Thermal Variance
McGuire Nuclear Station requests continuation of its 316(a) thermal variances for 95
Degrees Fahrenheit (Deg F) for the months of January-June and October- December and
99 Degrees Fahrenheit (Deg F) for the months of July—September. The basis for
continuation of the 316(a)thermal variances include:
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 plant discharges or other discharges in the plant site area
which could interact with the thermal discharges; and
c) There are no changes to the biotic community of the receiving waterbody which
would impact the previous variance determinations.
Results of our Lake Norman monitoring program have been sent annually to the NC DEQ
Division of Water Resources (Water Sciences Section). Due to the volume of these
previous submittals, copies of the cover letters transmitting the results are enclosed as
Appendix VIII. These documents are hereby acknowledged by reference to be part of the
permit renewal application package.
The site currently has an approved lake monitoring plan in support of our 316 (a) thermal
variances and we request continued approval of our monitoring plan. An updated Lake
Norman Study Plan is being submitted for review and is enclosed as Appendix IX.
Specific changes proposed for the Lake Norman (McGuire Nuclear Station) 316(a) Study
Plan include:
1. Fish community sampling will occur only during even number years as opposed
to annually;
2. Water quality and water chemistry sampling will be conducted twice per year
(winter and summer) as opposed to quarterly; and
3. Chlorophyll a sampling will be collected once per year (during the summer) as
opposed to quarterly.
Our proposed Lake Norman (McGuire Nuclear Station) 316(a) Study Plan is being
provided within the context of 40 CFR 125.73(c) based upon historic Balanced and
Indigenous Population (BIP) in Lake Norman as influenced by the McGuire Nuclear
Station. In accordance with previous Duke Energy/NC DEQ DWR conversations
(Safrit/Grzyb June 5, 2019), it is our understanding the opportunity for US EPA to
review this updated Lake Norman (McGuire Nuclear Station) 316(a) Study Plan will be
coordinated between NC DEQ DWR and US EPA Region IV during the NPDES permit
renewal process.
316 (b) Cooling Water Intake Structure Rule
In accordance with Part I, Condition A(22) of the existing NPDES permit, McGuire
Nuclear Station is in the process of submitting the appropriate reports as required by
Cooling Water Intake Structure Rule 40 CFR Part 125.95. Due to the significant volume
associated with this submittal, these documents are hereby acknowledged by reference to
be part of the permit renewal application package. The documents will be submitted to
NC DEQ DWR on or before August 30, 2019.

Please note that no stormwater related information is included in this NPDES permit
renewal application package since the McGuire Nuclear Station is covered by Industrial
Stormwater NPDES Permit No. NCS000020.
Requested Permit Changes
McGuire Nuclear Station requests consideration of the following permit change
suggestion:
1. The current permit contains two conditions which overlap in function:
A. (6) CLEAN WATER ACT SECTION 316(a) THERMAL VARIANCE(Oulfall 001)
The thermal variance granted under Section 316(a) terminates on expiration of the
NPDES permit. Should the permittee wish a continuation of its 316(a) variance
beyond the term of this permit, reapplication of such continuation shall be submitted
in accordance with 40 CFR Part 125, Subpart H and Section 122.21(1)(6) not later
than 180 days prior to permit expiration. Reapplication shall include a basis for
continuation such 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 plant discharges or other discharges in the plant site area which could
interact with the thermal discharges; and c)there are no changes to the biotic
community of the receiving waterbody which would impact the previous variance
determination.
The next 316(a)studies shall be performed in accordance with the Division of Water
Resources approved plan. The temperature analysis and the balanced and indigenous
study plan shall conform to the specifications outlined in 40 CFR 125 Subpart H and
the EPA's draft 316 Guidance Manual, dated 1977. The EPA shall be provided an
opportunity to review the plan prior to the commencement of the study.
and
A. (16)LAKE NORMAN AQUATIC ENVIRONMENT MAINTENANCE
MONITORING PROGRAM
The Lake Norman aquatic environment maintenance monitoring program approved
by the Division of Water Resources shall be continued. The monitoring results shall
be submitted annually.
Part I A. (16) is redundant and is addressed via Part I A (6) and therefore is not
necessary. Both requirements have been met during the current permit term and as a
part of this permit renewal request. The monitoring programs for Lake Norman
developed, implemented and conducted for more than thirty (30) years have shown
no adverse impacts to the biotic communities of Lake Norman, neither by the
McGuire Nuclear Station nor with the consideration of the combined effects of
McGuire and/or Marshall Steam Station. As mentioned previously, an updated Lake
Norman Study Plan specific to the McGuire Nuclear Station is being submitted foe
review and is enclosed as Appendix IX.
Duke Energy recommends Part I A. (16) be removed due to the redundant nature of
the two requirements.

This permit renewal package is being submitted at least 180 days prior to the permit
expiration date as required by NC GS 143-215.1 (C). and Part II, Section B Condition
No. 10 of NPDES Permit No. NC0024392.

PART C-If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in
column 2-a for all such GC/MS 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 outfalls,and nonrequired GC/MS 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
acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 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(all 7 pages)for each outfall.See instructions

PART C-If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in
column 2-a for all such GC/MS 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 outfalls,and nonrequired GC/MS 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
acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 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(all 7 pages)for each outfall.See instructions
for additional details and requirements.

CONTINUED FROM PAGE 3 OF FORM 2-C NC0024392 005 McGuire Nuclear Station
PART C-If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in
column 2-a for all such GC/MS 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 outfalls,and nonrequired GC/MS 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
acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 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(all 7 pages)for each outfall.See instructions
for additional details and requirements. I

OVERVIEW
McGuire Nuclear Station is a two unit nuclear steam electric generating station. It is owned and
operated by Duke Energy Carolinas LLC. Each unit has a four loop pressurized water reactor.
Reactor fuel consists of uranium oxide pellets clad in zirconium alloy fuel rods. Reactor heat
absorbed by the Reactor Coolant System (primary side) is transferred to four steam generators to
produce steam (secondary side) sufficient to drive a turbine generator with a design net electrical
rating of 1180 megawatts.
The nuclear reaction is controlled by control rods and chemical neutron absorption. Boric acid is
used as a chemical neutron absorber and to provide borated water for emergency safety injection.
During reactor operation, changes are made in the reactor coolant boron concentration.
A schematic diagram of water use and waste water discharges for McGuire Nuclear Station is
attached as Appendix III. It is possible for any of the discharges to contain low levels of
radioactivity. All discharges of radioactivity are regulated by the Nuclear Regulatory
Commission in accordance with 10 CFR Part 20 and 10 CFR Part 50. The following is a brief
description of the major systems.
STATION INTAKE
All water for McGuire Nuclear Station is withdrawn from Lake Norman through a dual intake
system, a surface and a subsurface system. These systems supply the Main Condenser Cooling
Water(RC), Conventional Low Pressure Service Water(RL),Nuclear Service Water(RN), Fire
Protection System (RF/RY), and Containment Ventilation Cooling Water System (RV).
Surface Intake
McGuire Nuclear Station has two power generating units with four Condenser Cooling Water
(RC)pumps per unit. There are two intake screens per pump for a total of 16 screens. The
intake screens are back washed on an intermittent basis to prevent differential pressure buildup
across the intake screens. The frequency of cleaning is determined by the amount of debris on
the screens. Approximately 8,500 gallons of water is used to backwash each screen. The water
is returned to Lake Norman at the intake bay. The backwash water is raw lake water. No
chemicals are used in the backwash water.
Subsurface Intake
The subsurface intake (Low Level Intake) is located near the bottom of Lake Norman at Cowans
Ford Dam. There are six low-level intake pumps with a capacity of 150,000 GPM each.
Currently only 3 pumps are operational. The Unit 2 pumps have been taken out of service.
During certain times of the year,this system pumps cooler water from the bottom of the lake
(hypolimnion - perpetually colder water in the lower part of the lake) and mixes it with the
warmer water in the surface intake structure during times of high lake surface water
temperatures. At all times of the year,the Low Level Intake(LLI) supplies water to the RV and
RN Systems.
Page 4 of 22

The LLI lines are periodically drained to the Catawba River just below the Cowan's Ford Dam
for inspection.
NUCLEAR SERVICE WATER
The Nuclear Service Water System (RN) is a safety related, once-through, non-contact cooling
water system. The RN System supplies cooling water to various heat loads in both the primary
and secondary portions of each unit. There are two pumps per unit (four pumps total) which can
deliver 17,500 GPM per pump. The water supply for this system is from Lake Norman or the
Standby Nuclear Service Water Pond (SNSWP). Water from Lake Norman is supplied by the
RC system from the surface intake byor the Low Level Intake (LLI). The normal source of
Y
( )
water is the LLI system. The normal discharge is to Lake Norman through Outfall 001.
The SNSWP is a 34.9 acre pond designed to provide cooling water for the safe shutdown of the
station in the event Lake Norman becomes unavailable. The level in the pond is maintained, per
requirements of the McGuire Nuclear Station Technical Specifications, by pumping water from
Lake Norman into the pond. The pond overflows to the Catawba River via the Wastewater
Collection Basin (WWCB), Outfall 005. The pond also receives storm water runoff from a
drainage area of approximately 100 acres. At times,the RN System is aligned to take suction
from the SNSWP and discharge back to the SNSWP. This recirculation mode is used for testing
purposes of the RN system and flow balances.
Because of accelerated corrosion of RN System components, some components may have
corrosion inhibitors added. Corrosion inhibitors may contain nitrites, borates, carbonates,
silicates, hydroxides,triazoles, and azoles. Low levels of one or more of these corrosion
inhibitors would be discharged at environmentally acceptable levels.
Macrofouling by Corbicula(Asiatic clams) and Dreissena(Zebra Mussels) can impact the safe
operation of the station. Zebra Mussels have not been problematic to date in Lake Norman but
other utilities have experienced macrofouling with Zebra Mussels. Microbial influenced
corrosion (MIC) has caused failures of piping and heat exchanger tubing due to pitting. Non-
oxidizing biocides, chlorine, or sodium hypochlorite may be used at concentrations,which will
not impact the environment to address macrofouling and MIC. Surfactants,which act as
biopenetrants may be added along with biocides to improve their efficacy. To prevent mud
fouling of components cooled by the RN System, dispersants may be added.
As of August 2019, there are no chemical additions made to the RN system.
CONTAINMENT SPRAY HEAT EXCHANGERS
To mitigate corrosion of carbon steel, a wet lay-up system is in use on the Containment Spray
System Heat Exchangers (NS). Various corrosion inhibitor solutions containing nitrites, borates,
azoles, and triazoles may be used. The corrosion inhibitor solution is released 5 to 10 times per
year per heat exchanger(2 heat exchangers per unit)to either the SNSWP or Lake Norman via
Outfall 001. This occurs during flow balance and heat exchanger performance testing. Each
heat exchanger has a capacity of 3600 gallons. Organic biocides may be added for biofouling
control.

CONVENTIONAL LOW PRESSURE SERVICE WATER
The Low Pressure Cooling System(RL) supplies cooling water for various functions on the
secondary(steam) side of the station. The system takes suction from the RC crossover lines and
supplies cooling water to various motor bearings, seals, lube oil coolers, vacuum breaker valves,
and a blowdown separator. Discharge is normally back through the RC System. RL is the
supply for the plant's Outsourced Water Treatment System (OWTS).
FIRE PROTECTION SYSTEM
The Fire Protection Systems (RF/RY)provides the plant with fire protection water. The system
is equipped with two 200 GPM jockey pumps which normally take suction from the RN System
via the RL System. One pump is normally sufficient to maintain standby readiness of system
water supply and pressure. If system pressure drops due to demand,the second pump is used to
supplement the jockey pump system capacity. In the event the jockey pumps can no longer
supply enough water to maintain system pressure, there are three 2,500 GPM main fire pumps
which will start as necessary to maintain system pressure. The fire protection system is treated
with an oxidizing biocide, when water temperatures are greater than 62° F,to a concentration of
approximately 1- 4 ppm total residual oxidant, to control bio-growth in the system's piping. The
fire protection system uses sodium silicates for corrosion control. The fire protection system is
used as the back-up source of water for bearing lubrication and gland seal for both the Main
Intake Condenser Cooling Water Pumps and the low level intake pumps. System operability is
demonstrated by periodically testing of the system. A summary of the current testing schedule
follows:
Functional verification of the main fire pumps is performed monthly to assure operability. Pump
suction is taken from Lake Norman and discharged directly back into the lake via the Main Fire
Pump recirculation lines. The water used for this testing is untreated lake water.
Each valve on each hydrant is stroked semiannually to assure proper operation. At this same
time, each hydrant is opened and flushed to verify flow. Very little water is discharged. Any
water discharged during testing is discharged to yard drains which discharge to the SNSWP or
WWCB.
Other routine tests are performed periodically to ensure operability of the RF/RY System. These
tests include pump head curve and pump starts in which the water is recirculated back into Lake
Norman at the Main Intake Structure. Water is also pumped through the system to ensure there
are no obstructions in the lines.
OUTFALL 001
Inputs to Outfall 001 include discharges from the RC, RL, and RN systems. Outfall 004
combines with Outfall 001 before discharging into Lake Norman. Storm drains along the
discharge canal also discharge to Outfall 001.
Page 6 of 22

Condenser Cooling Water
The RC System is a once through, non-contact cooling water system which removes heat
rejected from the main and feedwater pump turbine condensers and other miscellaneous heat
exchangers. Each of the two power generating units has four RC pumps for a total of eight(8)
pumps. The flow for each unit depends on the number of pumps operating as shown by the
following table:
Number of Pumps Operating Total Flow/Unit(GPM)
1 254,000
2 640,000
3 867,000
4 1,016,000
The operational schedule of the pumps of each unit is a function of the intake water temperature
and the unit load. At 100% load and with the intake temperature near its summer high four RC
pumps per unit are used. During winter when intake temperatures are lower, three pumps may
be used.
Condenser cleaning is accomplished by mechanical means using the "AmertapTM" system. This
system circulates small sponge rubber balls through the condenser continuously. There are 8
AmertapTM pumps per unit, 16 altogether. Each system (2 systems per unit, one for main
condenser and one for the FWPTs (Feedwater Pump Turbines)has a capacity of approximately
1240 balls. The balls are injected on the inlet side of the condenser and are retrieved on screens
on the discharge side of the condenser. Periodically some balls escape the retrieval system and
are discharged through Outfall 001. Efforts are made to minimize the loss of balls within the
system.
It could become necessary to institute chemical control for macroinvertebrate infestation, general
corrosion, and microbiologically induced corrosion (MIC). Chemicals anticipated to be added
include chlorine (sodium or calcium hypochlorite), organic biocides, dispersants, and corrosion
inhibitors. The corrosion inhibitors include nitrites, carbonates,triazoles, borates, triazoles, and
azoles. Discharge concentrations would be maintained below permitted discharge levels. There
are no plans to begin chemical control additions as of August 2019.
MNS had previously suspected the presence of Asiatic clams in a section of the RC system
referred to as the "RC Crossover". In Spring 2017, MNS visually identified the presence of
Asiatic clams in the section of the RC system which connects the Unit 1 and Unit 2 RC systems.
The original plan was to perform localized clamicide injections (EVAC) into this piping.
However, divers were used to mechanically remove the clams in Fall 2018. Injection of any
clamicide is not anticipated to be performed without significant need and preparation. Visual
nof the piping will again be performed in 2026.

Discharge concentrations of any treatment chemicals will be maintained below permitted
discharge levels.

Ventilation Unit Drains
The Ventilation Unit Condensate Drain Tanks (VUCDT) collects condensate from air handling
units from each reactor building. Each VUCDT(1 per unit) has a volume of 4,000 gallons.
This condensate typically has little radionuclide contamination. The condensate is sampled for
radionuclide contamination before being released. If the results of this sampling indicate the
need,the VUCDT contents are transferred to the Floor Drain Tank(FDT) for processing through
Outfall 004. If no processing is needed,the condensate is released from the VUCDT via the RC
System piping to Lake Norman (Outfall 001).
Note: Outfall 004 and the VUCDTs discharge through the same piping to Lake Norman through
Outfall 001.
During refueling outages, a portion of the ice in the ice condenser is melted. The ice melt is
normally routed to the WC system via the Turbine Building Sumps, however on occasion the ice
melt may be routed through the VUCDT. This drainage contains small amounts of boron. Boron
is used as a neutron absorber in the ice to control reactivity.
During outages the Component Cooling System (KC) Heat Exchangers may be drained to the
VUCDT as well. Permission was granted for this discharge in a permit modification approved
by NCDENR on April 11, 2002.
316 (a) Study and Thermal Variance
A 316(a) study was submitted to the state on August 9, 1985 and a 316(a) variance was granted
on October 18, 1985. Plant operating conditions and load factors remain unchanged and are
expected to remain so for the term of the permit. An annual Lake Norman aquatic environment
maintenance monitoring program was implemented on July 8, 1987. A copy of this report is
submitted annually to the Environmental Sciences Section of the Division of Water Resources at
NCDENR and to the NC Wildlife Resources Commission (NCWRC). No obvious short term or
long term impact of station operations have been observed in water quality, phytoplankton,
zooplankton or fish communities since the inception of this program. Additionally, Duke Energy
is not aware of any changes to plant discharges or other discharges in the plant site area which
would negatively impact the thermal discharge or biological habitat of Lake Norman. The
annual reports have historically shown Lake Norman continues to have a balanced indigenous
population of fish and other aquatic organisms. Within the renewal package cover letter, Duke
Energy is requesting both continued approval of our 316(a)thermal variances and updates to the
Lake Norman Study Plan. The Study Plan can be found in Appendix IX.
There were multiple fish kills in the vicinity of the McGuire Nuclear Station Intake during the
current permit period. Duke Energy Fisheries Personnel have investigated the fish kills and
determined they were due to natural lake conditions and not associated with McGuire Plant
operation.

OUTFALL 002
Outfall 002 discharges treated wastewater from the Conventional Wastewater Treatment(WC)
System through a Parshall flume to the Catawba River below Cowans Ford Dam. The WC
System consists of a polyurethane coated concrete Initial Holdup Pond (200,000 gallon
capacity),two parallel PolyflexTm Textured HDPE geomembrane-lined Settling Ponds (2.5
million gallons each), and a concrete based Geothane Lined Final Holdup Pond (1 million gallon
capacity). Normally, inputs are received in the Initial Holdup Pond (IHP) but can be routed
directly to an in-service Settling Pond if needed. The IHP serves as a common mixing point for
all wastewater, a surge dampening function to the remainder of the system, and allows heavy
solids to settle for periodic removal. Retention time in the IHP is 12 to 24 hours. Solids
removed from the IHP are dewatered and disposed of in a permitted landfill.
Flow is directed from the IHP to the in service Settling Pond. Caustic, acid, and/or other
chemicals may be added as necessary. Sulfuric acid and sodium hydroxide may be added for pH
control or to precipitate various chemical compounds. Coagulants may be added to facilitate the
settling of lighter solids. Additional treatment may include chemical oxidation with hypochlorite
(calcium or sodium)or catalyzed hydrogen peroxide. Retention time for each of the settling
ponds ranges between 6 and 12 days. The Settling Ponds can discharge to the FHP or directly to
the Catawba River. Treatment and discharge are normally on a batch basis. During normal
operations,the FHP is bypassed.
The FHP can be aerated and may be used to remove any persistent oxygen demand or provide
additional holdup capacity. The capability is available for recirculation intra- or inter- basin.
Discharge to the Catawba River was modified in the summer of 2014 to a gravity only discharge
with normal flow rates between approximately 650 and 800 GPM. Maximum flow is determined
by pond level and lower flow rates can be obtained by use of the system effluent isolation valve.
The pH of the discharge from the WC System is adjusted to within permitted limits by the
automatically controlled addition of CO2 (carbon dioxide).
The WC System accepts all conventional plant wastes except sanitary sewage. Inputs to the
system are from the Turbine Building Sumps, Water Treatment Room Sump, Closed Cooling
Systems, the Standby Shutdown Facility, Diesel Generator Room Sumps, Laboratory Drains,
Landfill Leachate. Steam Generator Blowdown, Wet Layup Drains, and the Unwatering Pump
discharges may occasionally be routed through this system as well. Several other buildings also
have inputs to the WC system, including the Vehicle Maintenance Facility, McGuire Office
Complex,Nondestructive Examination Lab, Island Labs, and the McGuire Medical Facility.
These systems typically contain low levels of radioactive hydrogen (tritium). The activity is
monitored and accounted for as part of the radioactive release process.
Water Treatment Room Sump
The demineralized water system (YM) for the plant is produced in a separate building located to
the southwest of the Administration Building. Inputs to the Water Treatment Room Sump are
minimal and may consist of rinsate of empty hydrazine, ammonia, carbohydrazide,
dimethylamine containers and backflow preventer drains. In addition, floor wash and sample
Page 9 of 22

line flush water are routed to this sump. Antifoaming agents and wax strippers are routinely
present in this waste stream. Rinsate from empty microbiocide containers (used in the closed
cooling systems) may be periodically added to this sump. The drains in the plant Auxiliary
Electric Boiler Room also route to this sump. Additionally, inputs from the McGuire Island
Industrial Waste System are routed to the sump. See the Island Industrial Waste section for
additional details on these inputs. The Water Treatment Room Sump discharges to the WC
System via the Initial Holdup Pond.
Filtered Water System
The filtered water system has been abandoned in place and is no longer used.
Drinking Water
Drinking Water for the McGuire Site is supplied by the Charlotte/Mecklenburg Utility
Department.
Demineralized Water System
Outsourced Water Treatment Building(OWTS)
The site has replaced the plant water treatment system with a vendor operated system. While the
process is similar,there are some changes to waste streams. The treatment process consists of
chlorination, filtration, dechlorination, reverse osmosis, electrodeionization (EDI) and ion
exchange.
Sodium hypochlorite is used for chlorination. Instead of diatomaceous earth filters,
ultrafiltration (UF) is used. This eliminates the waste filter media(DE)which was previously
produced. The UF filters are backwashed periodically to remove accumulated lake solids. At
times cleaning cycles are combined with backwashes for the UF filters. Sodium hypochlorite,
hydrochloric acid and sodium hydroxide may be used to clean the UF fibers. Backwash and
cleaning waste water is routed to the WC system Initial Holdup Pond for treatment. UF filtered
water is pumped to a 25,000 gallon storage tank at the new building.
The new process does not use carbon filtration, eliminating carbon filter backwash wastewater
and the need to dispose of waste carbon. Sodium bisulfite is used to dechlorinate filtered water
before it is pumped to the reverse osmosis units and UF Filter backwash water prior to it being
discharged to the Initial Holdup Pond.
Reverse osmosis is performed with reject flow, approximately 100 gpm max flowrate, routed to
the Wastewater Collection Basin. Antiscalents are injected into the RO feed. The RO system
requires periodic cleaning using surfactants, acids or caustic chemicals. Any spent cleaning
solutions are routed to the WC system for treatment.
Electrodeionization (EDI) units remove dissolved minerals from the water. Reject water from
the EDI unit is sent back to the UF filtered water storage tank for reprocessing. The EDI units
are also cleaned periodically with the same cleaning system used for RO. As of August 2019,
the EDI units are not in service.
Page 10 of 22

The demineralization system consists of modular, replaceable mixed ion exchange resin beds.
When the resin beds are exhausted,the resin is replaced with new or regenerated resin. Any
regeneration of resin is performed off site. This eliminates the demineralizer waste streams
including the 75,000+gallons of regenerant wastes previously sent to WC.
Turbine Building Sumps
The Turbine Building Sumps (TBS), one for each unit, receive inputs from leakage, drainage,
and liquid wastes from equipment and floor drains located in the Turbine Building. Inputs
include Groundwater Drainage Sumps (WZ), Auxiliary Electric Boiler Blowdown, Steam
Generator Blowdown, air handling units, Diesel Generator Room Sumps, lab drains, floor
washes, normal condensate system leakage, and condensate polisher backwashes. Other possible
inputs may include RC unwatering, closed cooling system drainage, and steam generator wet
lay-up/drain down. Periodically, condensate from air compressors is processed through an oil
water separator and routed to the TBS then to the WC Initial Holdup Pond. The TBS pump out
to the WC Initial Holdup Pond. If radioactivity limits are exceeded,theses sumps may be routed
through the Radwaste Liquid Waste Monitoring(WM) System (Outfall 004) or directly to RC
(Outfall 001) depending on the treatment needed. All radioactive releases are controlled and
regulated by the Nuclear Regulatory Commission (NRC). Discharges from the TBS may also be
routed to RC (Outfall 001) if system inventory is high or for periodic testing.
Chemicals which may be present in the TBS include the following:
• ammonia
• hydrazine
• carbohydrazide
• 3-methoxypropylamine (MPA)
• dimethylamine (DMA)
• Glycol (standby diesel coolant)
• microbiocides
• corrosion inhibitors (examples include: molybdate, nitrite,tolyltriazole, etc.)
• janitorial cleaning products
• ethylene glycol (from ice melt)
• Boric Acid/Borax (from ice melt)
• miscellaneous system/component cleaning products (low—volume wastes not associated
with chemical metal cleaning)
• laboratory chemicals
• poly acrylic acid (PAA)
• surfactants
• dispersants
During refueling outages, a portion of the ice in the ice condenser is melted. The ice melt is
routed to WC via the Turbine Building Sumps. This drainage contains small amounts of boron.
Boron is used as a neutron absorber in the ice to control reactivity.
Additionally, small amounts of oil have also been found to accumulate on the ice in the ice
condensers. The source of the oil is from pneumatic tools used to vibrate the ice from the
condenser's ice baskets.
Page 11 of 22
I.

Diesel Generator Room Sumps
The Diesel Generator Room Sumps (WN), receive inputs from the leakage or drainage of the
four, diesel generator engine cooling water, fuel oil, and lubrication systems. Each diesel
generator room has two sumps. The smaller sump has a volume of 600 gallons and one pump
with a capacity of 25 GPM. The larger sump has a volume of approximately 4,000 gallons and
contains two pumps with a rated capacity of 450 GPM each, and a third pump, with a rated
capacity of 50 GPM.
Each of the four engine cooling water systems has a volume of 800 gallons. The systems may be
treated with various corrosion inhibitors which may contain molybdate, hydroxides, borates,
silicates,triazoles and azoles. Miscellaneous biocides and dispersants may also be added.
Infrequently, but at any time a portion or all of each cooling system may be drained and the
coolant discarded via the diesel room sumps to the turbine building sumps to the WC system.
Lab Drains
There are several analytical laboratories on site which discharge to the WC System. These
discharges contain small quantities of typical laboratory chemicals used in analytical procedures.
The island environmental labs discharge to the WC System as well. Further discussion of this
waste stream is provided in the Island Industrial Waste section on page 16.
The lab sinks in the Island Technical Services Center(TSC), building 7406, drain to CMUD.
There are signs on all of the TSC lab sinks telling lab personnel not to dispose of any chemicals
down the lab sink drains. There is very little chemical use in these labs. The TSC labs perform
weight calibration, and sound and vibration analysis.
Condensate Polisher Backwash
Over time, trace impurities in the condensate system increase in concentration. In order to
maintain the integrity of the condensate system, the condensate is processed through condensate
polishing vessels. Each unit has 4 vessels. Condensate polishers act as filters and if chemistry
conditions require it, an overlay of ion exchange resin is added over the filter elements. The
resin allows for the capture of soluble contaminants. On average,the vessels are backwashed on
a monthly basis. If conditions require, backwashes are performed more frequently. Each
backwash requires approximately 10,000 gallons of condensate or YM water. When ion
exchange resin is used,the backwash will also contain 15-20 cubic feet of resin and 120
milliliters of polymer. Backwash water is discharged to the WC system. When resin is used,the
backwash is routed to a decant tank where the resin is captured. Normally, the spent resin is
pumped into a liner, de-watered and shipped to a low level radioactive waste disposal site. This
resin may also be discharged to the WC System or to the Liquid Waste Monitoring System
(WM) depending on levels of radioactivity and volume.
Steam Generator Blowdown
There are four steam generators (SG) per unit at McGuire for a total of eight steam generators.
Each has an operating volume of 16,000 gallons. Each unit is provided with a Steam Generator
Blowdown Recycle System. Steam generator blowdown is continuous at a rate of approximately
Page 12 of 22

200 gallons per minute per unit. Normally, the blowdown is directed to either the condensate
polishing demineralizers or to the steam generator blowdown demineralizers. SG Blowdown can
be routed to the WC System via the Turbine Building Sumps if needed.
During normal operation, hydrazine is added to the condensate system for oxygen scavenging.
The hydrazine concentration is maintained within a range of 25-200 ppb. 3-methoxypropylamine
is added for pH control. The steam generators and hotwell are placed in wet lay-up if a unit is to
be in extended shutdown or per management direction. Each unit is normally shutdown every 12
— 18 months for refueling and maintenance.
Dispersants may be used in the plants Steam Generators to control corrosion and sediment
buildup,therefore the potential exists whereby rejected blowdown waste water may contain
small amounts of the dispersant.
Steam Generator Wet Lay-up
Wet lay-up is the method used for protecting the steam generators against corrosion during
inactive periods. Typically,this will only be performed 1-2 times during a unit outage.
Chemical additions are made up in a 50 gallon addition tank. Normally, 40 gallons of 12%
Carbohydrazide and 20 gallons of 40% 3-methoxypropylamine (MPA)are made up for transfer
to the steam generators. Any remaining chemical solution is drained to the WC System via the
Turbine Building Sump. Prior to returning the unit to operation,the wet layup solution in the
steam generators may be drained to the WC System or WM System via the TBS.
The hotwell on each unit has a volume of approximately 250,000 gallons. During each unit
shutdown or per chemistry management direction, the hotwell is placed in wet layup.
Approximately 300 gallons of carbohydrazide are added to achieve a target concentration of 100
ppm carbohydrazide with the pH adjusted with MPA. If Carbohydrazide is not available,
sufficient hydrazine is added to achieve a target concentration of 75 ppm. Prior to returning the
unit to operation, this wet layup solution is discharged to the WC System or WM System via the
TBS.
Auxiliary Electric Boiler Slowdown
The Auxiliary Electric Boiler is supplied feedwater from the condensate system. Trisodium
phosphate is added as an electrolyte. The blowdown from the boiler may contain these
chemicals and approximately 1-2 ppm suspended solids. Blowdown is routed to the WC System
via the TBS.
Groundwater Drainage System
The Groundwater Drainage System (WZ) is designed to relieve hydrostatic pressure from the
Reactor and Auxiliary Buildings by discharging groundwater collected in sumps to either a yard
drain or the TBS. There are three groundwater sumps with two 250 GPM sump pumps each.
Two of the sumps discharge to the TBS while the third sump discharges to a yard drain which is
routed to the Standby Nuclear Service Water Pond (SNSWP).

RC System Unwatering
The RC System piping for each of the two units has a total volume of approximately 2 million
gallons. Whenever a unit is scheduled for refueling, periodically during other shutdowns, and
for condenser tube leaks, the system must be un-watered for purposes of maintenance. Un-
watering must continue while maintenance is performed because of leakage by the valves in the
approximately eleven(11) foot diameter RC piping. The maximum un-watering rate is
approximately 2,000 GPM and the water is essentially untreated lake water. Treated liquid
radioactive waste effluent(Outfall 004)discharges into a crossover line between the RC System
of the two units. During un-watering,the possibility exists for trace amounts of radioactivity to
be released into the water from the un-watering process because of isolation valve leak-by. All
radioactivity is accounted for and regulated by the NRC. The principle discharge route of the
un-watering is through the WWCB. However, it may be routed through the WC System for
short periods of time.
Closed Cooling Systems
There are several closed cooling systems within the station. The largest, Component Cooling
(KC) system has a volume of approximately 30,000 gallons. There are Unit 1 and Unit 2 KC
systems. The main components of these systems are constructed of carbon steel. To mitigate
corrosion of the carbon steel, various corrosion inhibitor solutions which may contain nitrite,
borate, carbonate, azole,triazole, silicate, phosphate, and molybdate compounds are used.
Dispersants may also be used to control corrosion and reduce fouling. Biocides such as
gluteraldehyde, isothiazolin and DBNPA can be used to prevent microfouling. Surfactants
which act as biopenetrants may be added to improve efficacy. The systems may need to be
drained, individually, for non-routine maintenance. Should this occur,these systems would be
drained to the RC discharge, or the WC System, or the WM System, if contaminated with
radioactivity.
Standby Shutdown Facility
The Standby Shutdown Facility(SSF) is an alternate and independent means to shut down the
station during emergencies. The independent power supply for the SSF is a diesel generator
system. The SSF contains a sump to collect system leakage, floor wash, and drainage of the
equipment for maintenance. The closed cooling system for the diesel generator uses corrosion
inhibitors which may contain nitrite, borate, carbonate, azole,triazole, silicate,phosphate, glycol
and molybdate compounds. Biocides such as gluteraldehyde, isothiazolin and DBNPA can be
used to prevent microfouling. Surfactants which act as biopenetrants may be added to improve
efficacy. Based on maintenance requirements and/or system chemistry monitoring, system
coolant is drained and captured for re-use or recycling.
Steam Generator Cleaning
Each electrical generating unit contains four steam generators which have a nonoperational
capacity of approximately 25,000 gallons each. There has been no chemical cleaning of the
steam generators to date, but the possibility exists where cleaning may be required. The actual
chemicals used for cleaning will depend on the type of fouling, and may include use of the
chemicals listed below.
Page 14 of 22

Miscellaneous System/Component Cleaning
Other systems/components (such as strainers, piping, HVAC heat exchangers, etc.) are cleaned
periodically because of scaling or plugging. Some cleanings are done by rinsing or by high
pressure washdown with water only(hydrolasing). Other times additives may be used to
improve cleaning efficiency. Solutions utilized are dilute acids, caustics, detergents or other
cleaning agents which do not attack the base metal. Typically, only small volumes of waste are
generated. Chemicals utilized by these methodologies, alone or in combination, may include the
following:
Alkaline Boilout Solutions
non-ionic surfactants
anionic surfactants
cationic surfactants
sodium hydroxide
soda ash
trisodium phosphate
disodium phosphate
monosodium phosphate
sodium bicarbonate
Acid Solutions
hydrochloric acid
sulfuric acid
phosphoric acid
formic acid
hydroxyacetic acid
sulfuric acid
citric acid
nitric acid
Acid Solution Additives
thiourea
ammonium bifluoride
oxalic acid
EDTA Compounds and HEDTA
pH adjusted tetra-ammonium EDTA
tetra-ammonium EDTA
di-ammonium EDTA
hydroxyethylenediaminetriacetic acid
tetrasodium EDTA
Page 15 of 22

Miscellaneous Compounds
chlorothene
sodium chloride
potassium permanganate
aqua ammonia
ammonium persulfate
antifoam
sodium sulfite
chlorine
The wastes from these cleanings are analyzed to determine proper waste disposal. These
cleaning solutions are released through the WC System or WM System depending on levels of
radioactivity.
Island Industrial Waste
Industrial Waste from the McGuire Island is collected and routed to the plant Water Treatment
Room Sump and eventually to the WC System through a dedicated discharge pipe. Industrial
Waste consists of small quantities of lab chemicals from analysis in the Duke Energy Corporate
Labs in Building 7405 and Building 7403 (McGuire Technical Training Building), and some low
level radioactive liquid waste. The radioactive waste is accounted for through McGuire's
radioactive effluent license.
Landfill Leachate
The McGuire Site operates a synthetically lined landfill (Permit 60-04 Indus), which is located
on Duke Energy property, across Highway 73, from the McGuire Plant. The landfill began
operation in January 1992. The area of the landfill is approximately 5 acres. The landfill accepts
only non-hazardous solid wastes,which contain no free liquids.
The leachate collection system is designed to collect rainwater which falls directly onto the
landfill. In the landfill cells, a perforated pipe collects the leachate which is then routed to the
leachate collection pond. The leachate system is designed to collect a maximum of 68,000
gallons. From the leachate collection pond, the leachate is pumped to the WC System Initial
Holdup Pond. The Leachate also contains pump seal water which comes from a well at the
landfill. The estimated average flow from the landfill leachate system is 200 GPD. This will
vary according to rainfall amounts. The leachate is sampled semi-annually. The results are
submitted to the N.C. Department of Environment, Health, and Natural Resources, Solid Waste
Section, per the Landfill permit requirements.
McGuire Garage
The McGuire Garage conducts maintenance on a variety of vehicles and heavy equipment.
Examples include cars,trucks, boats, fork lifts, cranes, etc. All industrial waste generated at this
facility is routed through an oil water separator to the WC System via the Initial Holdup Pond
(IHP). To add weight to some equipment, water is added to the tires. To prevent the water from
freezing, calcium chloride is added. Approximately 500 gallons of this solution is generated
Page 16 of 22

each year. Some of this solution is reused. Portions not reused are discharged into the Initial
Holdup Pond.
McGuire Office Complex
All industrial waste generated in this building is routed to the WC system via the Initial Holdup
Pond. Waste from an oil water separator is also routed to the WC system. The average daily
flow has not been estimated due to the highly intermittent nature of the flow but it is expected to
be less than 5 GPD (Gallons Per Day).
Office Shop Facility
All industrial waste generated in this building is routed to the WC system via the Initial Holdup
Pond. Waste from an oil water separator is also routed to the WC system. The average daily
flow has not been estimated due to the highly intermittent nature of the flow but it is expected to
be less than 5 GPD (Gallons Per Day).
Nondestructive Examination
Current trend is the use of computed radiography(CR)which uses a plate to capture the image
and the image is scanned directly into the computer. There are no staff radiographers on site.
Radiography would be performed by a vendor company. This method does not produce a waste
stream. The method described below may be used as an alternate process backup and as the
process to support other Stations.
Nondestructive Examination(NDE) includes X-ray testing of various components. The
photographic waste from X-raying is routed to the WC system via the IHP. NDE is usually
conducted in a building inside the protected area. If this X-ray processing unit is unavailable,
then a trailer which has the same type of equipment is utilized. The trailer also discharges the
photographic waste to the WC System via the IHP. When operating,the X-ray processing unit
has a waste stream which consists of approximately 0.0059 GPM developer replenisher working
solution, 0.0297 GPM fixer and replenisher working solution and 4.0 GPM water. The
developer replenisher working solution contains hydroquinone, glutaraldehyde, and potassium
acetate. The fixer and replenisher working solution contains ammonium thiosulfate and sodium
sulfate. Other developer working solutions and/or fixer replenisher working solutions with other
constituents may be substituted in the future. Silver is recovered from the process unit flow
before it enters the waste stream. The developing process can be operated a maximum of 30
hours per week(4.3 hours/day) but averages only 6 hours per week(1.2 hours/day). Operation
of the developing process results in a maximum of approximately 1040 GPD, with an average of
290 GPD of photographic waste discharging to the WC System.
Ice Condenser
During refueling outages, ice melt from the plants ice condenser is routed to WC. Potential
chemicals in ice melt include:
• Borax
• Boric Acid
• Trace amount of oil from ice removal pneumatic tools
Page 17 of 22

• Ethylene Glycol from spills from the ice making equipment. The amount of Ethylene
Glycol in the ice melt would be<55 gallons total.
OUTFALL 003
Outfall 003 was eliminated as of June 28, 1998. All sanitary wastewater is now discharged to
the Charlotte/Mecklenburg Utilities Department(CMUD).
OUTFALL 004
Outfall 004 discharges wastewater from the Radwaste Liquid Waste Monitoring System (WM).
This discharge combines with RC water before discharging through the concrete discharge
structure (Outfall 001) into Lake Norman as a batch discharge. All radioactive and potentially
radioactive liquids are collected, segregated, sampled and processed as needed prior to release.
These effluents are classified as recyclable or non-recyclable liquids. Recyclable liquids are
back totheirprocess streams. Non-recyclable liquids are collected and processed to
recirculated y q
Nuclear Regulatory Commission(NRC)requirements per 10 CFR Part 20 and 10 CFR Part 50
requirements prior to release. The type of processing depends on the type of waste. The
maximum discharge rate from WM is 120 GPM. The batch discharge flow for a Waste Monitor
Tank Release is a function of activity level, the number of RC pumps in operation, and the
resultant boron concentration in Lake Norman.
The WM collects waste in three subsystems; floor and equipment drains, laundry waste, and
ventilation unit drains. Chemicals which may be present in the WM System include:
boric acid
borax
nitrate
ammonia
carbohydrazide
Dimethylamine (DMA)
3-methoxypropylamine (MPA)
coagulants (example: Nalco 71259
lithium hydroxide
ethylene glycol (from ice melt)
corrosion inhibitors (examples include: molybdate, nitrite,tolyltriazole, etc.)
hydrazine
chlorine/hypochlorite
hydrogen peroxide
pump bearing cleaning chemicals
laboratory chemicals
surfactants
polyelectrolytes
miscellaneous system/component cleaning waste (low volume waste not associated with
chemical metals cleaning)
microbiocides
tool and component decontamination waste
janitorial cleaning products.
Page 18 of 22

The TBS can become contaminated with radioactivity. When this occurs, it can be pumped to
the Floor Drain Tank(FDT) or to the WM release point in the RC crossover line. Any chemicals
listed as being in the TBS have the potential to be present in the Waste Monitor Tank(WMT)
when the sump is routed to WM. Any solids generated in the treatment process are de-watered
and transported to a State licensed low level radioactive waste disposal facility.
Floor,Equipment, and Laundry Drains
Floor drains in the Auxiliary Building, drainage from all equipment(pumps,tanks, heat
exchangers, etc.) which process radioactive waste, waste from showers in the change rooms and
washing equipment which is used to decontaminate protective clothing, and waste from the Unit
1 and Unit 2 Containment Floor and Equipment Sumps are routed to the Floor Drain Tank
(FDT), Waste Evaporator Feed Tank(WEFT), Auxiliary Floor Drain Tank(AFDT), Auxiliary
Waste Evaporator Feed Tank(AWEFT), and/or Laundry and Hot Shower Tank(LHST). The
total tank volume is 125,000 gallons. These collection tanks are used interchangeably and/or as
backup and surge capacity for waste collection upstream of processing.
Radioactive wastes from these collection tanks are processed using filters and/or demineralizers
based on content. The processed effluent is collected in the Waste Monitor Tanks for sampling
and analysis prior to release. Release is to Lake Norman via the RC crossover line.
Chemical Volume and Control System
The Chemical Volume and Control System (NV) regulates the concentration of chemical neutron
absorber in the Reactor Coolant System (NC)to control reactivity changes and maintain the
required water inventory in the NC System. Boron, as boric acid is used as the chemical neutron
absorber.
Other control elements introduced into the NC System by the NV System include lithium and/or
carbohydrazide or hydrazine. Approximately 120 pounds of lithium hydroxide monohydrate is
used in each unit per year for pH control. The lithium is removed by demineralizers in the NC
System. Zinc acetate dihydrate is added to the NC system to achieve a concentration of 10 ppb
as zinc. This is done to reduce radiation exposure to plant personnel. Zinc will be removed by
demineralization in the NC system and by uptake into NC system piping oxide layers and
corrosion product deposits on fuel cladding. During start-up, carbohydrazide or hydrazine is
used as an oxygen scavenging agent. It is consumed upon unit heat-up, and is not used at any
other time. During shutdown, hydrogen peroxide is added to the NC System to facilitate the
removal of activated corrosion products.
Chemical Treatment in WM System
If it becomes necessary to oxidize sodium nitrite in a Waste Monitor Tank, hypochlorite
(calcium or sodium)or catalyzed hydrogen peroxide would be used. When this treatment is
performed, the Waste Monitor Tank is isolated, recirculated, and mixed. The tank is sampled to
ensure the nitrite has been oxidized. The addition of the oxidation chemicals should result in a
small residual of nitrite in the tank, since the oxidation chemicals will not be added in
stoicheometrical excess.

OUTFALL 005
Outfall 005 discharges flow from the Waste Water Collection Basin (WWCB). The WWCB is a
13.4 acre collection basin having a total capacity of approximately 40 million gallons with a
maximum drawdown capacity of approximately 11.1 million gallons. Discharge from the basin
ranges from 0 to 20,000 GPM. If excessive rain or unanticipated water from the Standby
Nuclear Service Water Pond(SNSWP) is being flushed, no holdup of the WWCB is possible.
Otherwise, holdup is accomplished by draining and anticipating plant and environmental inputs.
The WWCB provides sedimentation, natural neutralization, and skimming. The overflow from
the WWCB mixes with discharge from the WC System (Outfall 002) in a concrete apron and is
discharged to the Catawba River downstream of Cowans Ford Dam.
Inputs to the basin include overflow from the SNSWP, yard drains, RO reject flow,
miscellaneous Administrative Building drains, and RC System un-watering.
RO reject flow from the Water Treatment Building(OWTS) is routed to the WWCB through an
approximate 3-inch line.
Standby Nuclear Service Water Pond
The SNSWP is a 34.9 acre pond designed to provide water for the safe shutdown of the station in
the unlikely event Cowans Ford Dam is damaged and Lake Norman becomes unavailable. The
level in the pond is maintained, per requirements of the McGuire Nuclear Station Technical
Specifications (NRC requirements), by pumping water from Lake Norman into the pond. The
pond receives runoff from a drainage area of 100 acres. The containment spray heat exchanger
cleaning solutions (NS System) may occasionally be routed to the SNSWP. Overflow of the
SNSWP is routed to the WWCB.
Macrofouling sources (fish, algae, weeds, etc.) may be removed from the SNSWP using
chemical treatments. Rotenone can be used to remove fish. Rotenone is added at approximately
2 ppm for these treatments. The rotenone is neutralized using Potassium Permanganate at no
more than 4 ppm. Aquatic weeds and algae can be removed using Hydrothol 191 in the shallow
areas of the SNSWP at depths of 10 foot in depth or less. Hydrothol treatments would be
conducted in the late spring, summer and early fall.
To ensure the treatment chemicals are not released to the Catawba River prior to being non-toxic,
the WWCB is lowered approximately 5 feet below overflow. Additionally, the SNSWP is
lowered approximately 4 inches under overflow. To lower the pond levels, a low-level drain and
temporary pumps may be used to pump water to the WWCB and Catawba River via the overflow
pipe at the permitted Outfall 005. Treatments are controlled by procedure. Per agreement with
NCDENR toxicity tests would be performed on the ponds before water is released to the
Catawba River.
Administrative Building Drains
The Administrative Building drains include an HVAC sump, floor drains,janitorial sink, hot
water boiler, and chiller water system discharge. Any chemicals in the drains would include the
Page 20 of 22

typical commercial products used to clean and maintain the floors as well as closed cooling
corrosion inhibitors and microbicides from leakage/drainage of the HVAC Systems. The
corrosion inhibitors may contain nitrite, borate, carbonate, triazole, azole, and glycol compounds.
Additionally, HVAC cooling units are periodically cleaned using dilute coil cleaning solutions.
These cleaning solutions are typically flushed to storm drains near the building which drain to
the SNSWP or the WWCB. Volumes are less than 55 gallons. The coil cleaning solutions are
typically Phosphoric Acid or Hydrofluoric Acid based.
RC System Un-watering
The RC System piping for each of the two units has a total volume of approximately 2 million
gallons. Unwatering or dewatering is a plant term defined as removing the untreated lake water
from system piping by draining or pumping directly to the WWCB with no treatment. Whenever
a unit is scheduled for refueling, periodically during other shutdowns, and for condenser tube
leaks,the system must be un-watered for purposes of maintenance. Un-watering must continue
while maintenance is performed because of leakage by the valves in the approximately eleven
(11) foot diameter RC piping. The maximum un-watering rate is approximately 2,000 GPM and
the water is essentially raw lake water. Treated liquid radioactive waste effluent(Outfall 004)
discharges into a crossover line between the RC System of the two units. During un-watering,
the possibility exists for trace amounts of radioactivity to be released into the water from the un-
watering process because of isolation valve leak-by. All radioactivity is accounted for and
regulated by the NRC. The principle discharge route of the un-watering is through the WWCB.
However, it may be routed through the WC System for short periods of time.
Filtered Water
The Filtered Water system has been removed or reconfigured. The Filtered Water(YF) storage
tanks on the service building roof have been converted to demineralized water(YM) storage
tanks. Periodic flushes of the tanks are no longer performed.
HVAC Unit Drains
Several HVAC units have once through non- contact cooling water drains which discharge to
yard drains on the east and west sides of the Administrative Building. The flow from each of
these units is 10 GPM. These HVAC units are supplied by the Raw Water System (RL).
Additionally, HVAC cooling units are periodically cleaned using dilute coil cleaning solutions.
These cleaning solutions are typically flushed to storm drains near the building which drain to
the SNSWP or the WWCB. Volumes are less than 55 gallons. The coil cleaning solutions are
typically Phosphoric Acid or Hydrofluoric Acid based.
Yard Drains
Most yard drains discharge to the WWCB or SNSWP. The drainage area for the plant site is
approximately 250 acres. The yard drain system is described in McGuire's Stormwater
Supplemental Information and the sites Storm Water Pollution Prevention Plan(SWPPP).
Page 21 of 22

Turbine Building
There is a small pit in each unit's turbine building which gravity drains to the WWCB. These
pits are part of the drainage grid under the turbine building; no plant waste streams are routed to
these pits.
OUTFALL 006
System performance standards may require certain metal components be periodically cleaned
using an acid or caustic solution. This cleaning process can be reactive with the base metal of
the component. The waste metal cleaning solutions which are generated will be neutralized.
The other compounds will be mixed, oxidized, and/or precipitated as necessary for treatment.
The wastes from these cleanings will be sampled and analyzed to determine proper waste
disposal. If the wastewater is in specification it will be released through the WC System or WM
System. If the waste solution exceeds the permitted discharge limits, it will either be treated
further or sent off-site to an approved disposal facility.

SLUDGE MANAGEMENT PLAN

DUKE ENERGY
McGUIRE NUCLEAR STATION
SLUDGE MANAGEMENT PLAN
Conventional Waste Water System (WC) sludge is disposed of in the site's permitted
landfill. The landfill is a Subtitle D, Solid Waste Lined Landfill which only accepts non-
hazardous waste. Prior to disposal,the sludge is sampled,then removed and dewatered.
The old water treatment system which used diatomaceous earth has been replaced with a
new system which uses different types of filtration and is housed in the Outsourced Water
Treatment building.
Settleable solids from the site's waste systems are routed to the WC system and these
solids settle in the Initial Holdup Pond (IHP). This sludge includes solids from the filter
backwash process used in the Outsourced Water Treatment building. Other sources of
sludge are accumulation of dusts and silts from plant operation and the areas surrounding
the ponds. The site no longer uses diatomaceous earth filtration which was the major
contributor to sludge accumulation during previous operation. This will greatly reduce
the frequency of sludge removal from the IHP. It's estimated that sludge removal from
the IHP will not occur more often than 5-7 years.
Along with sludge removed from the IHP, it may become necessary to remove and
dewater solids from the two settling ponds or the Final Holdup Pond. Any removal from
the two settling ponds or the Final Holdup Pond (FHP)will be very infrequent.
Any radioactive contaminated sludge is disposed of per the site's NRC license and is
permitted by Mecklenburg County Solid Waste Department and the State of NC for
disposal in our landfill.
Sources of radioactivity in the sludge come from various sumps in the auxiliary and
turbine buildings.

MCGUIRE NUCLEAR STATION
1 Introduction
1 . 1 Background
McGuire Nuclear Station (MNS) consists of two units—completed in 1981 and 1984—each
rated at 1180 MW for a total net capacity of 2360 MW. The station is located in Mecklenburg
County, near Huntersville, North Carolina on the southern shore of Lake Norman. The lake,
which was formed in 1963 by the construction of Cowans Ford Dam on the Catawba River, was
built primarily as a source of non-contact condenser cooling water (CCW) for steam electric
stations and for hydroelectric power generation. In addition to MNS, two other electric
generating stations are located on Lake Norman: 360 MW Cowans Ford Hydroelectric Station
located 0.9 km west of MNS and 2030 MW Marshall Steam Station (MSS) located 18 km north
of MNS. Lake Norman is the largest impoundment in North Carolina with a surface area of
13,156 ha at full pond elevation 231.6 m above mean sea level. The lake has a shoreline length
of approximately 840 km and a mean depth of 10.3 m. The drainage area is roughly 4,662 km2
with a mean annual outflow of 75.6 cms at the dam and a theoretical retention time of 207 days.
The CCW system of MNS utilizes a once-through flow pattern where raw water from Lake
Norman is pumped over condensers to cool MNS system components and then discharged
back to the lake. The discharge of this heated water, referred to as "thermal discharge", requires
a Clean Water Act 316(a) thermal variance, which is regulated through a National Pollutant
Discharge Elimination System (NPDES) permit maintained by MNS (No. NC0024392). The
most recent NPDES permit for MNS was issued on June 1, 2016 and has monthly average
thermal discharge limits at Outfall 001 (CCW discharge) of 35°C (95°F) during October—June
and 37.2°C (99°F) during July—September. Based on monitoring results to date, these
temperature limits are expected to be protective of biological communities in the receiving
waterbody (i.e., Lake Norman).
1 .2 Environmental Monitoring History
The original MNS 316(a) demonstration study concluded, and the North Carolina Department of
Environmental Quality (NCDEQ) concurred, that MNS operations and thermal discharge limits
(35°C monthly average for the year) were compatible with the maintenance of a balanced
indigenous community (BIC) in Lake Norman (Duke Power Company 1985). Shortly after, a
permit modification was requested—and subsequently granted—that increased the thermal
discharge limit during July—September to 37.2°C. Along with this increased thermal discharge
limit, Duke Energy (then Duke Power) was required to submit an annual Maintenance
Monitoring Program (MMP) report to ensure the biotic community in Lake Norman was meeting
the definition of a BIC. The MMP was conducted in accordance with specifications outlined in 40
CFR 125 Subpart H and the USEPA draft 316(a) Guidance Manual. These reports were
submitted annually from 1988 to 2018 in lieu of 316(a) demonstration reports, and like the initial
demonstration report, the MMP reports concluded the permitted thermal limits ensured a BIC in
Lake Norman. In addition, Section A. (6) of the most recent MNS NPDES permit requires a Lake
Norman monitoring program approved by the NCDEQ that addresses the 316(a) thermal
for Outfall 001. This report, which has been included in the permit
discharge varianceprovisionp

2020 LAKE NORMAN§316(a)STUDY PLAN
MCGUIRE NUCLEAR STATION
renewal package, concluded that MNS operations were compatible with the maintenance of a
BIC in Lake Norman (Duke Energy 2019).
2 Study Goals and Objectives
Beginning in 2020 and in accordance with the upcoming NPDES permit, Duke Energy will
conduct studies to address the elements necessary to demonstrate a BIC in Lake Norman. The
goal of this Study Plan, therefore, is to outline the studies necessary for continuation of this
determination for the next permit renewal with the following two primary objectives:
1. Demonstrate the protection and propagation of a BIC of aquatic wildlife through
biological surveys, and
2. Perform physical and chemical analyses of the lake to assist in interpreting biological
data.
Data collected during this study will be evaluated against four primary BIC criteria defined in 40
CFR 125.71. The four criteria state that BICs are biotic communities typically characterized by:
a. Having diversity and representative trophic levels within expectations,
b. The ability to self-sustain through successful reproduction and recruitment over seasonal
changes,
c. Having adequate food items, and
d. A lack of domination by pollution tolerant species.
3 Study Plan
The following describes the study components of the proposed Lake Norman 316(a) study. The
different sampling locations, programs, and frequencies are included in Appendix A. All
sampling sites were categorized as falling within one of the following four zones:
Zone A — MNS thermally influenced area,
Zone B — MNS non-thermally influenced reference area,
Zone C — MSS thermally influenced area, and
Zone D— MSS non-thermally influenced reference area.
3.1 Fish
The 2020 Study Plan includes thirty-two (32) fish community sampling sites (shoreline
transects), the same number of sites as in recent years (Appendix A). The sites were selected
using a stratified random design to select for areas thermally vs non-thermally influenced and
those that were considered in the main channel versus "off-channel" (e.g., tributary arms and
coves).
2

2020 LAKE NORMAN§316(a)STUDY PLAN
MCGUIRE NUCLEAR STATION
Boat electrofishing (approximately 1,000 seconds of effort per transect) will be used to sample
each site according to standard fisheries methods (Miranda and Boxrucker 2009, Zale et al.
2012) and Duke Energy procedures. Transects will be sampled during the day with a boat
electrofishing unit using pulsed DC current. At each sampling site, a transect will be established
parallel to the shoreline that will not overlap with other transects. Species identification,
enumeration and individual total length (nearest millimeter) and weight (nearest gram) will be
recorded for fish collected in each transect. Fish will also be inspected for parasites and any
deformities. If fish are not identifiable in the field they will be preserved and taken back to the lab
for identification by Duke Energy fishery scientists. Water quality measurements (temperature,
conductivity, dissolved oxygen and pH) will be recorded at each transect with a calibrated probe
to evaluate environmental conditions at the time of sampling.
Fish community surveys will be performed in the spring and fall; however, sampling will occur
only during even number years in the next permit term instead of annually as in previous terms.
Review of historical data in Lake Norman suggest abundant and diverse communities occur
therein, and reducing the sampling frequency will still allow for BIC determination. Therefore, we
anticipate having at least two years of fisheries data (four total surveys) along with all historical
data for reference in the next environmental monitoring report.
Fisheries surveys will determine whether a reasonable and acceptable BIC exists in Lake
Norman despite the thermal discharge to the lake. As stated above, a BIC should be diverse,
contain different trophic levels, be self-sustaining, not be dominated by pollution-tolerant
species, and contain adequate food items. Metrics collected on fish species selected as
representative important species (RIS; Largemouth Bass Micropterus salmoides, Alabama Bass
M. henshalli, Bluegill Lepomis macrochirus, and Redbreast Sunfish L. auritus) will help
determine this BIC.
Data analysis will consist of total taxa numbers and biomass, catch-per-unit-effort, spatial
comparisons of RIS length distributions and condition, species pollution tolerance, trophic guild,
and hybrid complexes. To assess the potential thermal effects of MNS, comparisons will be
made between the MNS thermally influenced zone (Zone A) and its associated reference zone
(Zone B). Additionally, metrics will be calculated on a lake-wide basis.
3.2 Limnology
Beginning in 2020 and for the duration of the permit term, in-situ water quality monitoring and
water chemistry sample collection will be performed twice per year at 14 locations (Appendix A).
Chlorophyll a sampling for productivity assessment will be collected only in the summer, when
concentrations are expected to be highest (Duke Energy 2019). These data will be incorporated
into the 316(a) study to address any potential water quality/chemistry interactions with the
thermal effluent that may affect the BIC. A list of variables in the sampling program can be found
in Appendix A.
Field parameter measurements will be collected at each location with a calibrated probe starting
at the lake surface (0.3 m) and continuing to lake bottom. Collection of these data as well as
pre- and post-calibration processes will follow Duke Energy procedures. Water chemistry
samples will be collected as a surface grab (0.3 m) or as an integrated sample from the photic
3

2020 LAKE NORMAN§316(a)STUDY PLAN
MCGUIRE NUCLEAR STATION
zone (defined as two times secchi depth) as appropriate. Samples will be collected in high-
density polyethylene (HDPE) or polyethylene terephthalate (PET) sample bottles; bottles will be
pre-acidified where applicable. Water samples will be stored on ice and in the dark immediately
following collection to minimize the potential for physical, chemical, and/or microbial
transformation. All water chemistry sampling will follow Duke Energy procedures. Laboratory
water chemistry analyses will be performed by the Duke Energy analytical laboratory located in
Huntersville, NC. This laboratory maintains North Carolina Division of Water Resources
certification (Certification #248) to perform analytical testing of inorganic and organic
constituents. Chlorophyll a analyses will be performed by Duke Energy water quality and natural
resources laboratories in Huntersville or New Hill, NC.
Similar to fish community analyses, comparisons of water quality and chemistry results will be
made between the MNS thermally influenced zone (Zone A) and its associated reference zone
(Zone B). Additionally, metrics will be calculated on a lake-wide basis.
3.3 Habitat Formers
Qualitative habitat former (e.g., aquatic vegetation) surveys will be conducted in the summer
during at least two years in the next permit term. Presence and spatial distribution of habitat
formers will be recorded in thermally influenced areas and reference areas. All visible aquatic
vegetation species (submerged, floating and emergent) will be noted.
3.4 Phytoplankton and Zooplankton
Phytoplankton and zooplankton are generally considered to be low potential impact (LPI) biotic
categories, therefore narrative assessments of these components will be made and included
within the framework of the Lake Norman BIC. Scientific literature will be surveyed along with
any historical data collected from Lake Norman (Duke Energy 2019). The validity of using a
narrative approach can be found in the most recent 316(a) review by Coutant (2013).
3.5 Benthic Macroinvertebrates
As above for phytoplankton and zooplankton, benthic macroinvertebrates are generally
considered to be LPI biotic categories, therefore narrative assessments of these components
will be made and included within the framework of the Lake Norman BIC. Scientific literature will
be surveyed along with any historical data collected from Lake Norman (Duke Energy 2014).
3.6 Other Vertebrate Wildlife
In addition to aquatic biota, Duke Energy will conduct observations regarding "other vertebrate
wildlife" (wildlife) that are associated with aquatic habitats and/or rely on the waters for foraging,
reproduction, and other life functions (e.g., waterfowl, Bald Eagles, aquatic mammals,
amphibians).
According to the USEPA 1977 316(a) Technical Guidance Document, most sites in the United
States will likely be considered ones of LPI for other vertebrate wildlife simply because thermal
discharge plumes should not generally impact large or unique populations of wildlife (e.g.,
4

2020 LAKE NORMAN§316(a)STUDY PLAN
MCGUIRE NUCLEAR STATION
waterfowl concentrations, eagle wintering areas). Exceptions to sites classified as LPI would be
those few sites where the discharge might affect protected, RIS, or threatened and endangered
wildlife.
Observations for wildlife will be conducted by or under the direction of a Certified Wildlife
Biologist at sampling sites similar in general location to those being conducted for the fisheries
study component (Braun 2005; Heyer et al. 1994; Wilson et al. 1996). The observations will also
be conducted in the same time period (e.g., month, season) as the fisheries fieldwork.
Observations will be augmented by literature reviews of pertinent information (e.g., U.S. Fish
and Wildlife Services (USFWS) listed species county list, USFWS Information for Planning and
Construction (IPaC) database, facility-specific reports) which will enable Duke Energy to
prepare rationale regarding why the site should be considered one of low potential impact or an
exception to that designation.
3.7 Endangered Species
The USFWS map-based search tool IPaC, as well as other Duke Energy derived aquatic
species data was reviewed to determine the potential presence of federally listed species within
Lake Norman and the surrounding counties (USFWS 2018). The Carolina Heelsplitter
(Lasmigona decorata) is the only aquatic species identified in a search of the IPaC database.
The Carolina Heelsplitter is an endangered freshwater mollusk that requires cool, clean, well-
oxygenated water with silt-free stream bottoms and stable, well-vegetated stream banks
(USFWS 2018). The nearest known population of Carolina Heelsplitter and critical habitat
designated by the USFWS is located over 50 miles downstream from Lake Norman, and is
hydrologically disconnected by multiple dams. Therefore, no assessment of endangered
species will be included in the next BIC report.
4 Data Management
All data collected by Duke Energy for the MNS 316(a) study will be digitally recorded and
uploaded into Duke Energy's EQuIS (Earthsoft, Pensacola, Florida) database for retrieval and
analysis. Internal QA/QC processes will be implemented to ensure accuracy of data being
submitted to the EQuIS database.
5 Study Timeline and Reporting
The MNS 316(a) study will commence once the final study plan is approved by the NCDEQ and
USEPA, with an anticipated start in January 2020. Studies will continue through the life of the
NPDES permit, after which a five-year report will be prepared for the next permit renewal
application.

'In-situ water quality are measurements made in the water column using submersible sensors and recorded
on a computer.
2Analytical refers to water grab samples taken from the surface or photic zone, placed in sample bottles,
and returned to the laboratory for analysis.
3 Fish sampling will be conducted during even number years beginning in 2020.
Chlorophyll a and phytoplankton will be collected during the summer WQ/WC sample and/or anytime at
a given WQ/WC location if field parameters (DO Sat% >120 and pH > 9) indicate a bloom is
occurring; samples may also be taken if visual observations suggest so (i.e., noticeable bloom or fish
kill). A composite sample will be collected using an integrated depth sampler in the photic zone
(determined as 2 times secchi) or using a Van Dorn sampler. Phytoplankton samples will be
preserved and only analyzed if chlorophyll a is> 40 pg.
