Re. McGuire Nuclear Station
Authorization to Construct
Dear Ms. Sullins:
Duke Power Company requests an Authorization to Construct (ATC) to modify
:McGuire Nuclear Station's existing Conventional Waste and Sanitary Waste Disposal
Systems DES Permit C0024392). This modification will involve the Training
and Technology Center C) NPDES permitted systems (Permit # NC0026255).
The TIC NPDES Permit requires that the Sanitary Treatment System (Outfall 001)
comply with a Ironic toxicity test by April of 1995. To accomplish this, the TTC
Outfall, 001 will be routed to the McGuire Nuclear Station MNS) Sanitary Treatment
System )`, While we are making this modification, the rest of the outfalls
associated with the TTC NPDES Permit will be eliminated by routing them to the MNS
ConventionalWastewater Treatment System (WC), thus eliminating the TTC NPDES
Permit altogether. This will be accomplished by the end of April 1995.
In addition to this, plans are being made to eliminate the MNS Sanitary Waste System
(Outfall 003) by sending all of the site's sanitary waste to the Charlotte Mecklenburg
Utility Department for treatment. This connection is planned for early 1997. In order;
to do this, the industrial waste currently being handled in the MNS Sanitary System and
the industrial waste handled by the TTC permit will have to be separated d sent to the
S Conventional Waste Treatment System. (WC - Outfall 002).

FFV
The industrial waste requiring separation from MNS WT includes the Vehicle
Maintenance Facility, the McGuire Office Complex, Nondestructive Examination, and
the Medical Facility.
Therefore, this application for an ATC is for the following:
1. Separation of the TTC Permit industrial waste and sanitary waste;
2. Routing these two lines to the MNS Permitted systems WC and WT (respectively),
and
3. routing the industrial waste currently treated by the MS WT system to the MNS
WC System.
The flow diagram included in this permit application shows a schematic of how the
systems exist now and how they will discharge once this modification is complete.
Enclosed for your review are three (3) copies of the drawings, specification and
calculations which detail this project. Also enclosed is a check for $400.00 to cover
the permit application processing fee.
Please review this information at your earliest convenience. If there are any questions,
please call me at [phone].

will result in controlled compression of nitrile rubber 0-
rings without the requirement of a specific torque limit.
No secondary sealing compounds, rectangular gaskets,
elliptical 0-rings, grease or other devices shall be used.
The cable entry water seal design shall preclude specific
torque requirements to insure a watertight and submersible
seal. The cable entry shall be comprised of a single
cylindrical elastomer grommet, flanked by stainless steel
washers, all having a close tolerance fit against the
cable outside diameter and the entry inside diameter and
compressed by the entry body containing a strain relief
function, separate from the function of sealing the cable.
The assembly shall bear against a shoulder in the pump
top. The cable entry junction chamber and motor shall be
separated by a stator lead sealing gland or terminal
board, which shall isolate the motor interior from foreign
material gaining access through the pump top. E222S�ies,

considered acceptable.
The pump motor shall be a squirrel -cage, induction, shell
type design, housed in an air -filled, watertight chamber.
The stator winding shall be insulated with moisture
resistant Class F insulation which will resist a
temperature of 155°C (311'F) . The stator shall be dipped
and baked three times in Class F varnish and shall be
heat -shrink fitted into the stator housing. The use of
bolts, pins or other fastening devices requiring
penetration of the stator housing shall be rejected. The
motor shall be designed for continuous duty, capable of
sustaining a minimum of ten (10) starts per hour. The
rotor bars and short circuit rings shall be of aluminum.
A minimum of two thermal sensors shall be imbedded in the
stator winding end coils. These sensors shall be wired to
the control panel for use in conjunction with the external
motor overload protection.

PART 4 - CALCULATION
The following calculations are for the McGuire Nuclear Station Sanitary Sewer System
using the "Recommended Standards for Sewage Works," 1987 Edition and the North
Carolina State Plumbing Code, 1989 Edition.
Pump capacities shall be selected to equal or exceed influent flows to the lift stations.
The force mains shall be selected to convey the waste at a minimum flow of 2.5 gps
and a maximum flow of 10 fps.

1. Determine Pump Capacities
Design flows will be .based on an 8 hour working clay with a flow of 2
gallons per clay per capita. The total flaw per day is calculated to be
3,950 gallons per day (gpd) or 494 gallons per hour (gph).
Building 7419 - 90 x 25 = 2,250 gpd
Building 7420 - 68 x 25 = 1,700 gpd
3,950 gpd total or 3,950/8 = 494 gph
The peak design flow shall be approximately 4.1 times the hourly flaw of
94 gph which would result in a peak flow of :38 gph.
Each pump shall be selected to meet or exceed the minimum flow of 91
gpm or 2.5 fps through a 4" PE force main,

a. Calculate Static Head.
E PM 195 COMMERCIAL SANITARY SEWER CALCULATIONS 15 1 -

The maximum vertical distance for the minimum water level in the
proposed lift station basin to the highest paint in the discharge
piping is 9 feet.
. Calculate Friction Head.
Flow through the force main piping will be considered to be
turbulent. Therefore, the Hazen and Williams empirical
formula for determining friction drop shell be utilized.
Force main pipe was sized to ensure sufficient fluid velocity of at
least 2.5 feet per second.
Developed length of pipe from pump discharge to point of final
discharge is 1 490 feet.
Equivalent length for fittings and valves, add 10% equal 10

3. Determine the lift station basin size.
a. The lift station shall be constructed of watertight precast manhole
sections, 5 foot minimum diameter with a 5 font diameter
removable top. The top shall have an opening large enough to accept a
watertight, 36" x 48" (min.) access cover. A vent pipe shall be
provided through the top of manhole as shown on design drawings.
b. The depth of the lift station shall be determined by the pump operating
characteristics and the distance between the grade elevation and the
invert elevation of the gravity influent pipe. Based upon the selection of
89 gpm pump at 20' TRH, with an operating differential between
low level and high level of 2-0" , the bottom of the basin shall be
4.04 (min.) below the invert elevation of the gravity influent pipe. The
bottom elevation is 13.5' below the grade elevation of 9 ' + 0". The
top of the basin will extend 12" (inches min.) above the grade. See
design drawings.
C. A detention time of approximately 10 minutes is recommended. From
our lift station detail on the drawings, the 'pit is 5 feet in diameter.
There is 2 foot vertical distance between pump cut-off paint and
pump cut -on point. This volume equals 39.25 cubic feat, or
29:3.6 gallons.
ESPM 195 COMMERCIAL SANITARY SEWER CALCULATIONS 15410 -

t 34 gpm (maximum influent flow), the detention time from pump cut -cuff
to pump cut -on is;
29.6 gal.: 4 gpm = 8.6 minutes.
d. Total run time = 293.6 gallons gpm = 3.3 minutes
e. In the event of a power outage, assuming the outage occurred when the
water level in the lift station basin was at the alarm elevation, the
following storage of sewage would be available:
1. Additional storage capacity of basin.
Diameter - , 5'
Nigh 6" below grade to high level alarm) -,, =- ` 6 ".
Volume = 147.2 cu. feet = 1 101 gal.
2. Total time of storage assuming peak demand of` 4 gpm.
1,101 gal. divided by 34 gpm = 32.4 min.
Since the flows will be intermittent, i.e., demands will occur during
scheduled training, the restrooms will be closed if longer power outage
were to occur. A portable generator will be used to supply power to the
lift station and the restrooms will be opened for use.
The pumps will be supplied with local audible and visual alarms and,a 24
volt remote alarm to a control dialer located in 7420 which will call an
offsite security company which has 24 hour personnel coverage. The
security company will notify McGuire Nuclear Station's Facility
Management Department that there is a problem at Lift Station SS-1.

which will send an alarm to an offsite security company. The security company
Will notify McGuire Nuclear Station's Facility Management that there' is a
problem at Lift Station IW-5.

2. Determine the total dynamic head (TDH).
a. Calculate Static Head.
The maximum vertical distance for the minimum water level in the
proposed lift station basin to the highest point in the discharge
piping is 8 feet.
b. Calculate Friction Head.
Flow through the force main piping will be considered to be
turbulent. Therefore, the Hazen and Williams empirical formula
for determining friction drop shall be utilized.
Force main pipe was sized to ensure sufficient fluid velocity of at
least 2.5 feet per second.
Developed length of pipe from pump discharge to point of final
discharge is 900 feet.
Equivalent length for fittings and valves, add 15% equal 135

Subject: NPDES Permit Renewal, NC OG24392
McGuire Nuclear Station, Mecklenburg County
File: M-702.13
Certified: P 384 366 919
Dear Ms. Sullins:
Duke Power Company requests that the subject Permit e renewedand reissued. The
above referenced; Permit expires January 1,1995. Attached is the permit renewal
application Package which includes the following items:
1. EPA Form 1 - including Topographic and Site Maps (3 copies).;
2. EPA Form 2C - Including Priority Pollutant Analysis, Water Flow Diagram,
d Supplemental Information 3 copies).
3. Check in the amount of $4400.00 for the Permit Processing Fee.
Please review this application package at your earliest convenience and send us a letter
confirming its completeness. As required by GS 143-1.1 (C), this permit application
for renewal is being submitted at least 180 days prior to permit expiration
The McGuire Nuclear Site (which includes the Training and Technology Center,
NCO026255) will be connecting all sanitary sewer systems to the Charlotte Mecklenburg
Utillity Department (C MUi3) by 1997. We request that when you are drafting the new
permit, you consider the following changes which are under development for McGuire:

1. In the first phase, the Training and 'Technology Center's (TTC's) industrial
d sanitary wastewaters will be separated. The TTC's industrial
wastewaters will be routed to Mc ire's Outfall 002 (Conventional
Wastewater Treatment). The sanitary wastewater will be routed to
McGuire's Outfall 003 (Sanitary Treatment). The TT 's Outfall 001 will
be eliminated completely by April 1 1995 The remaining TTC Outfalls
(002, 003, and 004) will be eliminated by the end of 1995.
2. The industrial wastewaters from McGuire Office Shop, the McGuire Office
Complex, and the Nondestructive Examination Building,'will also be routed
to Mc ire's Outfall 002 (WC). This phase will be completed the end of
1995.
3. In 1991, a car wash will be installed at the McGuire Garage Facility. The
discharge from this car wash`will be routed to Mc it 's Outfall 00
(WC).
4. In the final phase of the project, McGuire!s sanitary Outfall 003 will be
connected to C `' D.Therefore, McGuire's Outfall 003 will be eliminated
by 1997. The industrial wastewaters from the Vehicle Maintenance Facility
d the Medical Facility will also be routed to S's Outfall 002 (WC)
during the final phase. The proper NPDES construction permits will be
obtained during this process as required.
Also, we would like to paint out that no data was available for Outfall 006 on Form C.
This outfall was not used 'during this time period; however, there are plans to use this
outfall in the near future. We would like to maintain this outfall in the new permit that will
be issued.
Thank you for your assistance with this permitting request. Should you have any question
or desire additional information, please contact Norma Atherton at [phone].
Very truly yours,

The McGuire Nuclear Site will be connecting all sanitary er systems Charlottwuecklenburg
Utility Department (CMUD) by 1997.
This project will be completed in phases. In Ow first phase, the Training and Technology Center's (TTC')
industrial ustrial nit ry wastewaters will be separated. The 7TVs industrial wastewaters will be routed to
MNS.a Ball 002 WC) and the sanitarywastewaters routed to MN&S Outfall003( Training and
Technology Center ( C) Outtall 001 under permit number NCO026256 will be eliminated completely b
April 1, 1995. The remaining C Outtalls ( ) will be eliminated by the end of 1996. The
industrial wastewaters from the McGuire Office Shop, McGuire Office Complex, and the Nondestructive
Examination building will also be routed to MN&s Outtall 002 (WC). This phase will be completed'by the
end of 1996.
The final phase of the project is to connect MN&s sanitary Outfall 003 to CMUD. Therefore, MNS Outtall
003 (Permit No. NC 2439 ) will be eliminated by 1997. The industrial wastewaters from the Vehicle
Maintenance Facility and the Medical Facility will also be routed to MN&s Qutien 002 (WC) during the final
phase. As part of this phase, a new car wash will be installed at the VehicleMaintenance Facility. The
maximum flour from the car wash is expected to be 2,000 GPD, with an average flow of 7GPD.
The
wash water will drain to a collection sump, then through an oittwater separator into the WC System (Uttall
). The proper NPOES permit modifications and construction permits will be obtained, as rewired, prior
to construction and operation.

OVERVIEW
USX# TMAW WRI
MOM
10 Cf�A Part 50. The 'following is a t6W description of th6 maW� soferns.
gjTAjj�LN INIAq
NUCLEAR SERVICE WATER
The RN is a safety related once through noncontact cooling water system, The Nuclear Service Water
System supplies cooling water to various heat loads in both the primary and secondary portions of each
unit. There are two (2) pumps per unit (four (4) pumps total) that are capable of delivering 17,500 GPM
per pump. The water supply is from Lake Norman or the Standby Nuclear Service Water Pond (NSW),
Water from Lake Norman is supplied by the RC system from the surface intake or by the LLI. The normal
source of 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 unlikely event that Lake Norman becomes unavailable. The level in the pond is maintained, per
1

across dirt or grass to yard drains. This test is performed only if the system is being chlorinated (i.e., the
jockey pumps are operating and the chlorine cylinders are open).
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 take Norman.
Water is also pumped through the system to ensure there are no obstructions in the lines, which
discharges water across paved lots, and grass to the yard drain system:
OUTFALL 001
Inputs to Outtall 001 include discharges from RC, RL, and RN. Outtall 004 combines with Outfall 001
before discharging into Lake Norman.
Condenser Cooling Water
The RC System is a once through noncontact cooling water system that removes heat rejected from the
main and fe dw ter pump turbine condensers and other miscellaneous heat exchangers. Each of the two
(2) power generating units has four (4) 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
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, three () and sometimes
four (4), RC pumps per unit are used. Curing winter when intake temperatures are lower; three (3) pumps
may be used. Condenser cleaning is accomplished by mechanical means (trade name'"Amertap°"). This
system circulates small sponge rubber balls through the condenser continuously. It may become
"necessary at times 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
may include nitrites, carbonates, triazoles, borates, triazoles, and azole . Discharge concentrations will
be maintained below permitted discharge levels.
A 316(a) study was submitted August 9,1985 and a 316(a) variance was granted October 18, 1 8 . Plant
operating conditions and load factors are unchanged and are expected to remain so for the term of the
reissued permit. A Lake Norman aquatic environment maintenance monitoring program was implemented
July 8, 1987 Duke Power Company is not aware of any changes to plant discharge or other discharges
in the plant site area which could interact with the thermal discharge or to biotic community of Lake
Norman. Duke therefore requests a continuation of the existing 316() variance.
OUTFALL 002
Outfall 002 discharges treated wastewater from the Conventional Wastewater Treatment (WC) System
through a Parshall flume to the Catawba River below Coans Ford Dam. The WC System consists of a
concrete lined initial holdup pond (IHP, 200,000 gallons), two (2) parallel clay -lined settling ponds (2.5
million gallons each), and a concrete lined final holdup pond (FHP, 1 million gallons). Normally, inputs
are received in the IHP but can be routed directly to an in-service settling pond. The IHP serves as a
common mixing point for all wastewater, a surge dampening function to the remainder of the system, and

also allows the heavy solids to settle for periodic

Filtered Water System
Water from Lake Norman is treated for process use. Filtration is performed by diatomaceous earth (DE)
pressure filters. Water from the RI_ System is treated with chlorine for disinfection purposes and
polyelectrolytes to coagulate colloidal material. The water is filtered through one (1) 750 GPM DE filter
while a second filter is in standby. The filtered water is stored in three (3) 42,500 gallon Filtered Water
Storage Tanks. When the administratively determined pressure differential across the filter is achieved,
the filter is backwashed thereby removing the filter cake. The system utilizes approximately 200 pounds
of DE and 32 ounces of polyelectrolyte per day.
Backwashing requires approximately 3,000 gallons of water per day. The backwash water containing the
waste DE and filtered solids is routed to the WC System, where solids are accumulated and ultimately
placed in a permitted landfill. Approximately every 2-5 years, citric acid is use to clean the filter elements
because of tube fouling, The approximately 110 gallons per cleaning of waste citric acid is treated for
disposal through Outfall 006.

Drinking Water System
The Chinking Water to the McGuire Site is applied by the Charlotte/Mecklenburg Utility Department:
Demineralized Water System
The Demineralized Water System (YM) provides high purity water for makeup to the primary and
secondary systems and for laboratory usage. There are two (2) carbon filters, one (1) 300 GPM reverse
osmosis unit (RO), ;and two () mixed bed regenerative demineralizers, with a system design flowrate of
475 GPM. Normally, two (2) carbon beds, the RO unit, and one (1) demineralier are in use while the
other demineralizer is being regenerated or is in standby. The YM System takes suction from the YF
System. The carbon filters remove organic substances and any residual chlorine. These filters may be
cleaned by bckwahing, steam cleaning, or rinsing. The cleaning may occur as often as twice per month
and is discharged via the water treatment room sump to the WC System (Outfall 002). For the cleaning,
15,000 gallons of water are used. Each carbon bed is replenished every six to twelve months. Waste
carbon is routed to the WC System or collected and deposited directly in a permitted landfill.
The RO unit provides pretreatment to the demineralizers. It consists of an integral series of filters and the
RO unit itself. Sulfuric acid is injected to the process stream to maintain propel' pH. Depending upon
system demands, the finished water (300 GPM) is supplied to the demineralizers. The reject flow (150
GPM) would be diverted to the WWCB (Outfall 005) The RO units are periodically cleaned based on
performance standards. The cleaning process may involve use of surfactants, acids, and caustics. When
this cleaning is conducted, it would be discharged via the water treatment sump to; the WC System (Outfall
002).
Regeneration of one deineralizr may occur as often as every month. To regenerate the resins, sulfuric
acid and sodium hydroxide are flushed through the bed. At the present time, each normal regeneration
takes approximately 90 gallons of 93% sulfuric acid, 400 gallons of 50% sodium hydroxide, and 75,000
gallons of YM. The amountsof required acid and caustic will vary as dictated by operational
requirements. Based on annual resin analysis results, the beds may be surfactant cleaned, caustic soaked
or brine soaked. The water from these cleanings is discharged via the water treatment room sump to the
VC System. The d miner liter beds are replenished approximately every six (6) to eight (8) years. Waste
resin is routed via the water treatment room sump to the WC System, and is ultimately placed in a
permitted landfill:
Turbine Building Sumps
The Turbine Building Bumps (TBS) receive inputs from leakage, drainage, and liquid wastes from
equipment and floor drains located in the Turbine Building. Inputs include' Groundwater Drainage Sumps
(W ),' Auxiliary Electric Boiler Blowdown, Steam Generator Blow own, filter air handling units, Diesel
Generator Room Sumps, tab drains, floor washes, normal condensate system leakage, and condensate
polisher backwashes. Other passible inputs include RC Unwatering, and steam generator wet laup
draindown. ;Periodically, condensate from air compressors is processed through an oil water separator
and routed to the TBS to the WC IHP.
Chemicals that may be present in the TBS include the following:
ammonia
boron
hyrazin
morpholine
ethanolamine

microbiocides
corrosion inhibitors
janitorial cleaning products'
miscellaneous system/componentcleaning products
laboratory chemicals
The TBS normally are routed to the WC System. However, if radioactivity limits are exceeded, these
sumps can be routed through the Radwaste Liquid Waste Monitoring ( M) System (Outfall 004) or directly
to RC (Outfall 001) depending on the treatment needed.. Very low levels of radioactivity' can be routed to
the WC System. All radioactivity is accounted for and regulated by the NRC.
Diesel Generator Room Sum
The Diesel Generator Room Sumps (KD) receive inputs from the leakage or drainage of the four (4) diesel
generator engine coaling water systems, fuel oil, and lubrication systems. Each diesel generator room has
two (2) sumps. The smaller sump has a volume of 600 gallons and one (1) pump with a capacity of 25
GPM. ' The larger sump has a volume of approximately 4,000 gallons, two () pumps with a capacity of
450 GPM, and a third pump with capacity of 50 GPM. Fuel oil and lube oil is collected in the "drip tank"
which is then' pumped to the Waste Oil Storage Tank (WOST),
Each of the four (4) engine cooling water systems has a volume of 500 gallons. The systems may be
treated with various corrosion inhibitors Which may include nitrites, hydroxides, borates, silicates, triazoles,
and azoles. Miscellaneous biocides and dispersants may also be added. Each system is drained and
flushed to the WC System, approximately once per year. Additionally, the fuel tail may contain residual
biocide, to reduce bacterial breakdown of the oil.
Lab Drains
There are several analytical laboratories within the plant, which drain to sumps that discharge to the WC
System. The discharges contain typical laboratory chemicals used in analytical procedures.
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 powdered ion exchange resin.
A condensate polisher is backwashed on an average of twice per month The backwash contains
approximately 15- 0 cubic feet of resin, 120 milliliters of polymer, and requires approximately 10,000
gallons of water. The resin may contain trace quantities of radioactivity from primary to secondary leaks.
It can be discharged to the WC System or to the Liquid Waste Monitoring System (W) depending on
levels of radioactivity:
Steam Generator Blowdown
Each of our four () generators per unit has a volume of 40,000 gallons. Each unit is provided with a
Steam Generator Blowdown Recycle System. Steam generator blowdown is continuous at a rate of
approximately 5,000 gallons per hour to maintain acceptable steam generator water chemistry. The
blowdown is directed to either the condensate polisher demineralizer or to the steam generator blowdown
demineralizer. If the blowdown water quality is unacceptable, it is rejected, It can be discharged to the
WC System or to WM System depending on levels of radioactivity.
During normal operation hydrazine is added to the condensate system for oxygen scavenging, The
hydrazine concentration is maintained within a concentration range of 2-200 ppb. Ammonia is added

for pH control. The steam generators and hotwell are placed in wet layup it a unit is to be in cold
shutdown for two days or more. Each until is normally shutdown on a 12 month cycle for refueling.
Wet lau

efficiency, the cooling system is flushed annually to the SSF which drains to the We System.
Steam Generator Cleaning
Each electrical generating unit contains'four {} steam generators that have a capacity of approximately
40,000 gallons each. There have been no chemical cleaning of the steam generators to date, but the
remote possibility exists that cleaning may be required. Should this need arise, more ihformation will be
provided to the Department seeking approval to conduct the cleaning process.
Miscellan s SysLem/Compgnent Cleaning
Other; systems/components (such as strainers, HVAC heat exchangers, etc.) may need to be cleaned
periodically because of scaling or plugging. Other components will be cleaned as necessary for various
fouling problems. Solutions utilized may be dilute acids or caustic sodas. Chemicals utilized by these
methodologies, alone or in combination, 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

These solutions are described in the Development Document for Effluent Limitations Guidelines and New
Source Performance Standards for the Steam Electric Rower Generating Point Source Category.
(Development Document):
The wastes from these cleanings will be analyzed to determine prosper waste disposal. These cleaning
solutions will be released through the WC System or WM System depending on levels of radioactivity,
Landfill Leachate
The McGuire Site operates a synthetically lined sanitary waste landfill (Permit 60-04), which is located on
Duke Power property, on the opposite side of Highway 73, from the McGuire Plant. The landfill began
operation in January 1992, The maximum active area of the landfill in current estimated usage is to be
0.45 acres, but the active area can be expanded to approximately 5 acres, as is needed. The landfill
accepts only nonhazardous solid wastes, which contain no free liquids.
The leachate collection system is designed to collect rainwater that falls directly onto the active portion of
the landfill. In the active 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 63,O00 gallons. From
the leachate collection pond, the leachate is pumped to the WC System Initial Holdup Pond. The Leacate
will also contain pump seal water. The estimated average flow from the landfill leachate system is 120
GPD. The leachate is sampled semi-annually and submitted to the N.C. Department of Environment,
-Health, and Natural Resources, Solid Waste Section, per Landfill Operation permit conditions.
Vehicle Maintenance Facility
The Vehicle Maintenance Facility conducts maintenance on all company automobiles and heavy
equipment. 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 are generated each year.
As it is generated, it is transported to the initial hold up pond and 'discharged,
C UTFAL.L 003
Outfall 003 discharges treated sanitary waste from the Sanitary Waste Treatment System (WT) to the
WWCB. The WT System is four (4) cell aerated lagoon system. The system was designed to process
domestic sewage from restroom, showers, lab drains, and site cafeterias. The lagoon provides a 5-day
retention time and will allow for variable level discharge, The wastewater effluent from the aerated lagoon
flowsthrough a sand filter, chlorinators, a chlorine contact chamber, and a parsall flume before
discharging to the WWCR.
The lagoon ;is lined with a flexible synthetic material such as hyp lon. It is divided into four (4) cells by
a curtain material such as a polymer coated polyester with a weighted chain ballast and floatation collar.
The first cell provides for a two day retention time and is kept in complete suspension by surface

contains ammonium thiosulfate and sodium sulfate. Other developer replenisher working solutions and/or
fixer and relenisher working solution with other constituents may be substituted in the future: Silver is
recovered from the processor flow before it enters the waste stream. The developing process is operated
a maximum of 30 hours per week (4.3 hours/day) but averages 6 hours per week (1.2 hours/day),
Operation of the developing process results in:a maximum of approximately 1041 GPD, with an average
of 290 GPD; of photographic waste discharging to the WT System. The flow from this system is very
intermittent.
Medical Facility
The primary effluent from the Medical Facility is domestic waste, but a minimal inflow from the Medical
Facility X-Ray process (i.e. photographic wastes) may also discharged. The chemical nature of this waste
stream does not differ substantially from the more voluminous processing unit located in the OA Vault.
Silver is recovered from the process flow before it enters the waste stream. The X-Ray processor operates
intermittently, Monday through Friday. The average flowrate 110 GPD, and the maximum flowrate 300

O TF LL 004
Outtall 004 discharges flow from the Radwaste Liquid Waste Monitoring System ( M). This flow combines
with the RC before discharging through; the concrete discharge structure (Outtall 001) into Lake Norman
as a batch discharge. All radioactive and potentially radioactive liquids are collected, segregated and
processed prior to release. These effluents are classified as recyclable or nonrecyclable liquids.
Recyclable liquids are recirculated back to the process streams. Nonrecyclable liquids are collected and
processed to Nuclear Regulatory Commission (NR) requirements (10 CFR Part 20 and 10 CFR Part 0)
prior to release with the type of processing depending 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 take Norman'.
The WM collects waste in three (3) subsystems (floor and equipment drains, laundry waste, and ventilation
unit drains). Chemicals that may be present in the WM System include:
boric acid
borax
nitrate
ammonia
morpholine
ethanolamine
lithium hydroxide
ethylene glycol "

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 T S may also be present in WM when the sump is routed to WM. Any solids generated in the
treatment process are solidified or deatered and transported to a State and NRC licensed low level
radioactive waste disposalfacility.
•r sRMa • i .
Ventilation Unit Drains
The Ventilation Unit Condensate Drain Tanks (VUCDT) collect condensate from air handling units from
each reactor building. Each VUCDT has a volume of; 4,000 gallons.
This waste typically has little radionuclide contamination and contains a small amount of boron from the
ice melt. The waste is sampled for radionuclide contamination, If the results of this sampling indicates
the need, the VUCDT content are transferred to the FDT for processing (Outfall 004) If no need for
processing is indicated, the waste is released from the VUCDT via the RC to Lake Norman (Outfall 001).
Twice per year a portion of the ice in the annulus in the reactor building is melted and drained to the
UCDT. The VUCDT could contain boron from the ice melt.
Chemical Volume and Control System
Chemical Treatment in WM System
casionally, it is necessary to oxidize sodium nitrate in the waste monitor tank using hypochlorite
(calcium or sodium) or catalyzed hydrogen peroxide. When this treatment is performed, the waste monitor
tank is isolated, recirculated, and mixed. The tank is sampled to ensure that the nitrate has been oxidized.
The addition of the oxidation chemicals should result in a small residual of nitrate in the tank, since the
12

oxidation chemicals will not be stoichiometrically added in excess.

APPENDIX I
Connection to Charlotte/Mecklenburg
Utility Department
The McGuire Nuclear Site will be connecting all sanitary sewer systems to the Charlotte/Mecklenburg
Utility Department (CMUD) by 1997.
This project will be completed in phases. In the first phase, the Training and Technology Center's (TTC's)
industrial and sanitary wastewaters will be separated. The TTC"s industrial wastewaters will be routed to
MNS's Outtall 002 (WC) and the Sanitary wastewaters routed 'to MNS's Outtall 003 (WT), The Training and
Technology Center (TTC) Outtall 001 under permit number NCO026255 will be eliminated completely by
April 1, 1995. The remaining TTC Outtalk (002, 003, 004) will be eliminated by the end of 1995, The
industrial wastewaters from the McGuire Office Shop, McGuire Office Complex, and the Nondestructive
Examination building will also be routed to MNS's Outfall 00 (WC). This phase will be completed by the
end of 1995:
The final phase of the project is to connect MNS's sanitary C uffall 003 to CMUD. Therefore, MNS Outtall
003 (permit No. NG0024 92) will be eliminated by 1997. The industrial wastewaters from the Vehicle
Maintenance Facility and the Medical Facility will also be routed to MNS's Outtall 002 (WC) during the final
phase. As part of this phase, a new car wash will be installed at the Vehicle Maintenance Facility. The
maximum flow from this car wash is expected to be 2,000 GPD, with an average flow of 700 GPD. The
wash water will drain to a collection sump, then through an oil/water separator into the WC System (Ouffall
002). The proper NPDS permit modifications and construction permits will be obtained, as required, prior
to construction and operation.

PART IV - EVALUATION AND RECOMMENDATIONS
Duke Power Company (DPC) has requested renewal of the subject
Permit. There have been no changes or modifications since the
Permit was last issued, however, there are several proposed changes
that need to be addressed at Permit reissuance. It is also our
understanding that this Permit will be placed on held until July,
1995, at which time it will be in line with the`Painswide
permitting schedule.
Below is `listed the activities proposed by DPC that will
require approval and/or a modification to the NPDES Permit prior to
implementation.
1. DPC intends to eliminate all of the outfalls from the nearby
Training and Technology Center {TT} by either connecting the
waste streams to existing McGuire treatment facilities.
Eventually, all sanitary waste generated at either McGuire or
the TTC will be treated by CMUD (projected to occur by 1997
Industrial wastewater from the TTC will be routed to Mcuire's
outfall 002 (by the end of 1995) and the sanitary wastewater
will be rerouted to McGuire's outfall 003 (by April, 1995).
The rerouting of the sanitary wastewater is expected to occur
prior to Permit r'eissuance. A modification of the current
Permit to include the additional wastewater is unnecessary
since Mcc-'Zuire's outfall 003 and the TT''s outfall 001 are
identical waste streams, however, DPC will need to demonstrate
that capacity does existatMcGuire to accept the wastewater.
2. Assorted industrial wastewaters from the McGuire office and.
Office Shop and the Nondestructive Examination Building will
also be routed to Mc uire's outfall 002.
. A car wash is planned for the garage at McGuire by 1996'and
the effluent will be treated and discharged through outfall
02.`
. Cutf ,l l 003 (sanitary wastewater)- is projected to be
eliminated by 1997 (connected to C UL) .
DPC had requested that outfall 00 (which has not been used to
date) remain in the Permit, however, since the wastewater
discharges through outfall 002, it is recommended that the waste
stream described in the application for out -fall 006 be included in
the waste stream for outfall 002 and that outfall 006 be eliminated
from the Permit. DPC will need to submit a revised application
authorizing this change,

Page Five
The renewal application appears to contain a more descriptive
narrative of the different` sources of wastewater that may enter the
various McGuire treatment facilities than found in previous
applications, Based on this information, additional monitoring
and ,or limitations may he necessary pending TSB's review of this
information.

OVERVIEW
Subsurface Intake
The subsurface intake (Low Level Intake) is located near the bottom of Lake Norman at Cowans Ford Dam,
There are six (6) low level intake pumps with a capacity of 150,000 GPM each. During certain times of
the year, this system pumps cooler water from the lake hypolimnion and mixes it with the warmer water
in the surface intake structure during times of high take surface water temperatures. At all times of the
year, the Low Level Intake (LLI) supplies water to RV and RN.
NUCLEAR SERVICE WATER
The FIN is a safety related once through noncontact cooling water system. The Nuclear Service Water
System supplies cooling water to various heat loads in both the primary and secondary portions of each
unit. There are two (2) pumps per unit (four (4) pumps total) that are capable of delivering 17,500 GPM
per pump. The water supply 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 or by the LLI. The normal
-source of water is the LLI system, The normal discharge is to Lake Norman through Outtall 001
The SNSWP is a 34.9 acre pond designed to provide cooling water for the safe shutdown of the station
in the unlikely event that Lake Norman becomes unavailable. The level in the pond is maintained, per

Drinking Water System
The Drinking Water to the McGuire Site is applied by the Charlotte/Mecklenburg Utility Department.
Demineralied Water System
The Demineralized Water System ( ) provides high purity water for makeup to the primary and
secondary systems and for laboratory usage. There are two (2) carbon fitters, one (1) 300 GPM reverse
osmosis unit (RO) and two () mixed bed regenerative dler in rali ers with a system design flowrate of
475 GPM. Normally, two (2) carbon beds, the RO unit, and one (1) dernineralizer are in use while the
other demineralizer is being regenerated or is in standby. The YM System takes suction from the YF
System. The carbon filters remove organic substances and any residual chlorine. These filters may be
cleaned by backwashing, steam cleaning, or rinsing. The cleaning may occur as often as twice per month
and is discharged via the water treatment room sump to the WC System (©uttall 002). For the cleaning,
15,000 gallons of water are used. Each carbon bed is replenished every six to twelve months. Waste
carbon is routed to the WC System or collected and deposited directly in a permitted landfill.
The RO unit provides pretreatment to the demineralizers. It consists of an integral series of filters and the
RO unit itself. Sulfuric acid is injected to the process stream to maintain proper pH. Depending upon
system demands, the finished water (00 GPM) is supplied to the demineralizers. The reject flow (50
GPM) would be diverted to the WWCB (Outfall 005). The ;RCS units are periodically cleaned based on
performance standards. The cleaning process may involve use of surfactants, acids, and caustics. When
this cleaning is conducted, it would be discharged via the water treatment sump to the WC System (Outfall
002).
Regeneration of one demneralir may occur as often as every month. To regenerate the resins, sulfuric
acid and sodium hydroxide are flushed through the bed. At the present time, each normal regeneration
takes'; approximately 90 gallons of % sulfuric acid, 400 gallons of 50% sodium hydroxide, and 75,000
gallons of YM. The amounts of required acid and caustic will vary as dictated by operational
requirements. Based on annual resin analysis results, the beds may be surtactant cleaned, caustic soaked
or brine soaked. The water from these cleanings is discharged via the water treatment room sump to the
C System.' The damineralizer beds are replenished approximately every six (5) to eight (3) years. Waste
resin is routed via the water treatment room sump to the WC System, and is ultimately placed in a
permitted landfill.
Turbine Building Sumps.
The Turbine Building Sumps (TBS) 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, 'filter air handling units, Diesel
Generator Room Sumps, lab drains, fluor washes, normal condensate system leakage, and condensate
polisher backwashes. Other possible inputs include RC Unwatering, and steam generator wet laup
draindown. Periodically, condensate from air compressors is processed through an oil water separator
and routed to the TBS to the WC IHP.
Chemicals that may be present in the TBS include the following:
ammonia
boron
hyrazine
morpholine
ethanolamine

Steam Generator Blowdown
Each of our four (4) generators per unit has a volume of 40,000 gallons. Each unit is provided with a
Steam Generator Blowdown Recycle System. Steam generator blowdown is continuous at a rate of
approximately 5,000 gallons per hour to maintain acceptable steam generator water chemistry. The
blowdown is directed to either the condensate polisher demineralizer or to the steam generator blowdown
demineralizer. It the blowdown water quality is unacceptable, it is rejected. It can be discharged to the
WC System or to WM System depending on levels of radioactivity.
During normal operation hydrazine is added to the condensate system for oxygen scavenging. The
hydrazine concentration is maintained within a concentration range of 25-200 ppb, Ammonia is added

efficiency, the cooling system is flushed annually to the SSF which drains to the WC System.
Steam Generator Cleaning
Each electrical generating unit contains four () steam generators that have a capacity of approximately
40,000 gallons each. There have been no chemical cleaning of the steam generators to date, but the
remote possibility exists that cleaning: may be required. Should this need arise, more ihformaton will be
provided to the Department seeking approval to conduct the cleaning process.
Miscellaneous System/Comr)onent Cleaning
Other systems/components (such as strainers, HVAC heat exchangers, etc.) may need to be cleaned
periodically because of scaling or plugging. Other components will be craned as necessary for various
fouling problems. Solutions utilized may be dilute adds or caustic sodas. Chemicals `utilized by these
methodologies, alone or in combination; include the following:
Alkaline Boilut Solutions
non-ionic surfactants
anionic surfactants
cationic surfactants
sodium hydroxide
soda ash
trisodium phosphate
disodium phosphate
monosodiumphosphate

The Nondestructive Examination (NDE) is --ray testing of various components. The photographic waste
effluent line is connected to the domestic waste line (T). NDE is usually conducted in a building inside
the protected area, It this X-ray processing unit is unavailable, then a trailer (just outside the North PAP)
which has the same type of process equipment will be utilized. The trailer also discharges the
photographic waste effluent to the domestic waste line ( T). When operating, the photographic waste
consists of approximately 4 GPM, 0.0059 GPM developer replenisher working solution, and 0.0297 GPM
fixer and re lenisher working solution. The developer replenisher working solution contains hydroquinone,
glutaraldehyde, potassium sulfite, and potassium acetate. The fixer and replenisherworking solution
10

contains ammonium thiosulfate and sodium sulfate. tither developer replenisher working solutions and/or
fixer and replenisher working solution with other constituents may be substituted in the future. Silver i
recovered from the processor flow before it enters the waste stream. The developing process is operated
a maximum of 30 hours per week (4 hours/day) but averages 6 hours per week (1.2 hours/day).
Operation of the developing process results in a maximum of approximately 1041 GPD, with an average
of 290 GPD of photographic waste discharging to the WT System. The flow from this system is very
intermittent.
Medical Facility
The primaryeffluent from the Medical Facility is domestic waste, but a minimal inflow from the Medical
Facility X-Ray process (i.. photographic wastes) may also discharged. The chemical nature of this waste
stream does' not differ substantially from the more voluminous processing unit located in the QA Vault.
Silver is recovered from the process flow before it enters the waste stream. The X-Ray processor operates
intermittently, Monday through Friday. The average flowrate 110 GPD, and the maximum flowrate 300
GPD, of photographic waste discharging to the WT System,
OUTFALL 004
outfall 004 discharges flow from the Radwaste Liquid Waste Monitoring System ( M). This flow combines
with the PIC before discharging through the concrete discharge structure (outfall 001) into Lake Borman
as a batch discharge. All radioactive and potentially radioactive liquids are collected, segregated and
processed prior to release. These effluents are classified as recyclable or nonrecyclable liquids.
Recyclable liquids are recirculated back to the process streams. Nonrecylable liquids are collected and
processed to Nuclear Regulatory Commission (NRC) requirements (10 CFR Part 20 and 10 CFR Part 0)
prior to release with the type of processing depending 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 (3) subsystems (floor and equipment' drains, laundry waste, and ventilation
unit drains).; Chemicals that may be present in the WM System include:
boric acid
borax
nitrate
ammonia
morphplin
ethanolamine
lithium hydroxide
ethylene glycol
corrosion inhibitors
hydrazine
chlorinelhypochlorite
hydrogen peroxide
pump bearing cleaning chemicals
laboratory chemicals
surfactants
polyelectrolytes
miscellaneous system/component cleaning waste
tool and component decontamination waste
janitorial cleaning products

Chemical Treatment in WM System
Occasionally, it is necessary to oxidize sodium nitrate in the waste monitor tank using hypochlorite
(calcium or sodium) or catalyzed hydrogen peroxide. When this treatment is performed, the waste monitor
tank is isolated, recirculated, and mixed. The tank is sampled to ensure that the nitrate has been oxidized.
The addition of the oxidation chemicals should result in a small residual of nitrate in the tank, since the

HVAC Unit Drains
Several HV C units have once through noncontact 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 RL:
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 cGuire's Stormwater Permit Application.
Reverse Osmosis
The Reverse Osmosis (RO) unitprovides pretreatment to the demineralized water system (YM). RO is
supplied by YF This system consist of an integral series of filters and the RO unit itself. Depending upon
system demands, the finished water (00 GPM) is supplied to the demineralizers. The reject flow (150
GPM) would be diverted to the WWCB (Outfall 005). The RO reject is to the YF water that can not pass
through the series of filters. This water is lake water with slightly elevated minerals.
The RO units are periodically cleaned based on performance standards. The cleaning process may
involved the use of surfactants, acids, and caustics. When this cleaning is conducted, it would be
discharged via the water treatment sump to the WC System (Outfall 002)
Performance standards require that certain metal components be periodically cleaned using an acid or
caustic solution. This cleaning actually attacks the base metal of the component. The waste metal
cleaning solutions which are generated will be neutralized. The other compounds will be mixed, oxidized,
andlor precipitated as necessary for treatment. The wastes from: these cleanings will be sampled and
analyzed to determine proper waste disposal. It permitted discharge limits allow, the waste will be released
through the WC System or WM'System. If the treated waste solution exceeds the permitted' discharge
limits, the waste metal cleaning solution will be properly disposed.
