2. Production Rates (industrial discharges only) in Pounds:
Information not available in any application submittals

requested from the applicant. This facility produces
electricity is is not quantifiable in pounds.
3. Description of Industrial Process (for industries only) and
Applicable CFR Part and Subpart: 40 CFR 423 - Steam
Electric Power Generation
4. Type of Treatment (specify whether proposed or existing):
Outfall 001: None other than a discharge canal
approximately 200 feet wide and 2,500 feet long for the
purpose of heat dissipation.
Outfall 002: Wastewater is treated in the plant's existing
conventional wastewater treatment system which consists of a
200,000 gallon initial holding pond, two (2) settling ponds
(in parallel) each with 2.5 million gallon capacity, a 1
million gallon final holding pond (aerated -diffused air) and
effluent PH adjustment consisting of automated CO2 addition.
The initial holding pond acts as a flow equalization basin.
This pond may be bypassed, depending on the nature of the
wastewater. The two settling ponds are operated such that
one pond remains in standby. Treatment can be enhanced by
the addition of coagulant aids and pH adjustment in these
ponds.
The effluent from the settling ponds may be discharged
directly to the receiving stream via outfall 002 or it may
be routed to the final holding pond. Effluent from the
final holding pond may be discharged through outfall Oct or
recirculated to the settling ponds, depending upon effluent
quality.
Outfall 003: The existing sanitary wastewater treatment
plant consists of a multicellular aerated -facultative
lagoon, a chlorine contact chamber (tablet), and a parshall
flume. The discharge from outfall 003 enters an impoundment
(WWCB), which also receives area surface runoff. The
overflow from the impoundment combines with the discharge
from outfall 002 prior to discharge into the Catawba River.
The sanitary wastewater treatment plant is designed for a
maximum of 64,000 gpd.
Outfall 004: The existing liquid radwaste system consists
of filters, demineralization, oxidation, and coagulation/
flocculation.
Outfall 005: The WWCB is essentially a large settling pond
(13.4 acres) with a surface baffle to skim debris and
floating oil (in case of a spill).

Page Five
Outfall 006: None
5. Sludge Handing and Disposal Scheme:
Outfall 001: None
Outfall 002: Sludges are disposed by landfarming at a
designated on -site disposal area. This disposal is
permitted by DEM Permit No. WQ 0001860.
Outfall 003: Sludge is periodically removed from the lagoon
and disposed at a municipal wastewater treatment plant.
Currently, the disposal is made at CMUD's McDowell Creek
Wastewater Treatment Plant.
Outfall 004: Sludges which accumulate in the liquid
radwaste system are disposed as low level radioactive wastes
at approved repositories such as Barnwell,, South Carolina.
Outfall 005: Due to the large size of the basin and the low
rate of solids accumulation, sludge removal is not routinely
necessary. If and when solids must be removed, Duke is
aware that the method of removal must be acceptable and/or
permitted by DEM.

PART IV - EVALUATION AND RECOMMENDATIONS
Luke Power Company has requested a
modification to the
existing NPDES Permit to include additional wastewater sources
which will ultimately discharge through
outfalls 002, 003 and
004. A description of each additional wastewater
input and the
outfa.11 from whence it will discharge is
found 'below.
Outfall 002. Duke Power Company proposes
to construct a
0.45 acre construction landfill on
property adjacent to the
McGuire site. At the landfill, a leachate
collection system
will be constructed and ultimately
tanked or piped to the
wastewater treatment facilities which
discharge at outfall
002. nuke Power Company has provided

The `majority of office trash is taken: to a municipal
landfill by a contracted vendor.
In a letter 'dated December 19, 1989, Mr. Griggs indicated
that the above estimates are conservative and may be higher
than the actual quantities. The proposed (estimated)
average daily flow is 0.001446 MGD of lea hate.
Typically, leachate from municipal solid waste landfills
contains high organic and inorganic constituents which may
prove detrimental to wastewater treatment plant performance
without' pretreatment. The nature of the waste to be placed
in McGuire's landfill is not typical of the waste found in
municipal landfills and the resultant leachate may pose less
of a risk of wastewater treatment plant disruption.
Nevertheless, consideration should be given to the proposed
pump and hauling of this wastewater and how it will be
introduced into the wastewater treatment system in order to
prevent a shock effect. Duke Power Company should provide a
detailed plan, including a leachate analysis prior to its
disposal in the wastewater treatment facilities discharging
at outfall 002.
Gutfall'003: Three (3) additional wastewater inputs are
proposed for connection to the sanitary wastewater treatment
system. All three wastewater inputs to this system will not
exceed the facility's hydraulic capacity. The three
additional wastewater sourcesare:
1. Veicle'Maintenance Facility - Wastewater generated
from building floor drains and vehicle wash pit. All
wastewater will be routed through an oil/water
separator (appropriately designed) and then into the
building sewer system. A small amount of degreaser i
used, however, this usage is considered to be minimal.
Projected wastewater flaw is 0.01920 MGD (maximum) and
actual daily usage should be much less.

Page 'Eight
. Construction and Maintenance Department °- The
wastewater is generated from floor drains in the repair
shows. The drains are for emergency purposes as floors
are not routinely washed down. All wastewater will
pass through an oil/water separator. Some oil (not
emulsified) may be present from milling machines.
Projected (maximum) flow is 0.0000 MGD.
. Quality Assurance Facility - A projected (maximum) flow
of 0.001 41 M D of photographic wastewaterwill be
generated at this facility, however, average flow will
be 0.000290 MGD. This Office requests that Tech
Services evaluate the proposed additives contained in
the application to determine whether their addition
will have a detrimental effect on the wastewater
treatment system.'
. Outfall 004 - Duke Power Company requests approval to
add hypohloite or catalyzed hydrogen peroxide in
order to oxidize sodium nitrite in the waste monitor
tank. The addition of these chemicals will result in a
small residual of nitrite which will be ultimately
discharged at outfall 004 Again, the assistance of
Tech' Services is requested to evaluate the effect of
this additional wastewater input to the proposed
wastewater treatment system.
Pending receipt and approval of a Waste Load. Allocation,; it
is recommended that the NP3ES Permit be modified to include thesei
additional wastewater sources.

5. Mass jDayMeasurements
a. The "monthly average discharge: is defined as the total mass of all
daily discharges sampled and/or measured during a calendar month on
which daily discharges are sample and measured, divided by the number
of daily discharges samples and/or measured during such month. It is
therefore, an arithmetic mean found by adding the weights of the

ihe number of days the tests were reported. The limitation is
Identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the, total mass of
all daily discharges sampled and/or measured during the calendar week
(Sunday -Saturday) on which daily discharges are sampled and measured,
divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean found by
adding the weights of pollutants found each day of the week and then
dividing this sum by the number of days the tests were reported. This
limitation is identified as "Weekly Average" in Part I of the permit.
C. The "maximum daily discharge" is the total mass (weight) of a
pollutant discharged during a calendar day. If only one sample is
taken during any calendar day the weight of pollutant calculated from
it is the ""maximum daily discharge." This limitation is identified as
"Daily Maximum," in Part I of the permit.

Part 11
Page 12 of 14
d. The "average annual discharge" is defined as the total mass of all daily
discharges sample and/or measured during the calendar year on which daily
discharges are sampled and measured, divided by the number of> daily
discharges sampled and/or measured during such year. It is, therefore, an
arithmetic mean found by adding the weights of pollutants found each day of
the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the
permit.
6. Concentration Measurement
8. The "average monthly concentration," other than for fecal coliform
bacteria, is the sum of the concentrations of all daily discharges
samples and/or measured during a calendar month on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled
and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the
concentration of a*composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected
during that calendar day. The average monthly count for fecal coliform
lendar month. This limitation is identified as "Monthly Average"
,der "Other Limits" in Part I of the permit.
A tt average weekly concentration," other than for fecal coliform bacteria,
the sum of the concentrations of all daily discharges sampled and/or
.asured during a calendar week (Sunday/Saturday) on which daily discharges
e sampled and measured divided by the number of daily discharges sampled
d/or measured during such week (,arithmetic mean of the daily
mcentration values). The daily concentration value is equal to the
ncentration of a composite sample or in the case of grab samples is the
,itbmetic mean (weighted by flow, value) of all the samples collected during
at calendar day. The average weekly count for fecal coliform bacteria is
e geometric mean of the counts for samples collected during a calendar
ek. This limitation is identified as "Weekly Average" under "Other
wits"" in Part I of the permit.
e 11 maximum daily concentration" is the concentration of a pollutant
scharge during a calendar day. If only one sample is taken during any
leader day the concentration of pollutant calculated from it is the
nximum Daily Concentration". It is identified as "Daily Maximum" under
then Limits" in Part 1 of the permit.

Part II
Page 13 of 14
d. The "average annual concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily discharges sampled and/or
measured during a`calendar year on which daily discharges are sampled and
measured divided by the number of daily discharges sampled and/or measured
during such year (arithmetic mean of the daily concentration values). The
daily concentration value is equal to the concentration of a composite
sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The
average yearly count for fecal coliform bacteria is the geometric mean
of the counts for samples collected during a calendar year: This
limitation is identified as "Annual Average" under "Other Limits" in Part I
of the permit.
e. The "daily minimum concentration"' (for dissolved oxygen only) is the
minimum allowable amount of dissolved oxygen required to be available in
the effluent; prior to discharge. It is identified as "Daily Minimum"' under
"OtherLimits" in PartIII of the permit.
. Other Measurements
a. Flow, (M D): The flow limit expressed in this permit is the 24 hours
average; flow, averaged monthly. It is determined as the arithmetic mean
of the total daily flows recorded during the calendar month..
b. An "instantaneous flow measurement" is a measure of flow taken at the time
of sampling, when both; the sample and 'flow will be representative of the
total discharge.
Types cif Samples
a.' Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flaw, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
samples shall be no greater than hourly. Intervals between effluent; grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days, provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or :less.
grab Sample::` Crab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually,

9. Calculation of Means
a. Arithmetic Mean: The arithmetic mean of any set of values is the summation
of the individualvalues divided by the number of individual values.
b. Geometric Mean. The geometric mean of any set of values is the Nth root of
the product of the individual values where N is equal to the number of
individual values. The geometric mean is equivalent to the antilog of
the arithmetic mean of the logarithms of the individual values. For
purposes of calculating the 'geometric mean, values of zero'(0) shall be
considered to be one (1).
C. Weighted by Mow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the
respective flows.
10. Calendars
A calendar day is defined as the period from midnight of one day until midnight
of the newt clay. however, for purposes of this permit, any consecutive 4-hour
period that reasonably represents the calendar dray may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 11
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of
the Clean Water Act.

ACUTE TOXICITY TESTING REQUIREMENT (QRT Y)
Daphnid`48 hr - L 5
The pe 'ttee shall conduct mute toxicity tests on a aRqLterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms". The monitoring shall be performed as a Da hnia pule or
Ceriodaphnia 48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any two consecutive toxicity
tests be less than r %. Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The first test will be perf rmed gfter
thirty dfrom issuance of this permit during the months of 6LO Ml Y I)&
The parameter code for this test if using lea hn a ulex is TAA3D. The par titer code for this test
if using CeriodaDhnia is TAA3B. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in
which it was performed, using the appropriate parameter code. Additionally, ITEM Form AT-1
(original) is to be sent to the following address:
Attention; Environmental Sciences Branch

performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above;
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls shall constitute an invalid test
and will require immediate retesting(within '00 days of initial monitoring event), Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean found by
adding the weights of pollutants found each day of the week and then
dividing this sum by the number of days the tests were reported, This
limitation is identified as "Weekly Average" in Part I of the permit.
C. The "maximum daily discharge" is the total mass (weight) of a
pollutant dischArged during a calendar day. If only one sample is
taken during any calendar day the weight of pollutant calculated from
it is the "maximum daily discharge," This limitation is identified as
""Daily Maximum," in Part I of the permit.

d. The "average annual discharge" is defined as the total mass of all daily
discharges sample and/or measured during the calendar year on which dai
discharges are sampled and measured, divided by the number of dai
discharges sampled and/or measured during such year. It is, therefore,
arithmetic mean found by adding the weights of pollutants found each day
the year and then dividing this sum by the number of days the tests we
reported. This limitation is defined as "Annual Average" in Part I of t
permit.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform
bacteria, is the sum of the concentrations of all daily discharges
samples and/or measured during a calendar month on which daily discharges
are sampled and measured, divided by the number of daily discharges sample
and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (wqighted by flow value) of all the samples collected
during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during
calendar month. This limitation is identified as "Monthly Average"
under "Other Limits" in Part I of the permit.
b. The ""average weekly concentration,"other than for fecal coliform bacteria
is the sum of the concentrntions of all daily discharges sampled and/or

NPDES Permit Modification
Adding Inputs to 'treatment facilities
File: MC-702. 3
Dear Mr. Wilms:
Nuke Power Company is constructing a new vehicle maintenance facility at
the McGuire Nuclear Station site and desires to routethe wash water from
the vehicle wash pit to the McGuire domestic wastewater treatment (WT)'
system. In discussing the proposal with your staff, we were informed, than
since the WT system is permitted to treat only domestic waste, an
application for an NPDES permit modification' would need to be submitted.
In reviewing the application for modification, several additional small
inputs were discovered and are included in the application. Additionally,
new landfill is being proposed to be constructed in 1992. it is desirable
to route any leachate from the landfill to the conventional 'wastewater
treatment. (WC) system. This proposed input is included in the modification'
application.;
Please find enclosed triplicate copies of the application to modify the
NPDES permit and a , check (no. 244050) for $ 00.00 for the permit

System Description
Additional Inputs to Conventional Wastewater Treatment WC st tfall
t3I }
Outf all 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 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 (F, 1
million gallons). Normally, inputs are received in the IHP but can be
routed directly to an in-service settling pond. The IHP Nerves a a common i
mixing paint for all wastewater, a surge -dampening .function to the
remainder of the system, and allows the 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: on a State licensed landfarm or
landfill.
Flow is directed to the in-service Nettling pond through: the chemical
addition building were caustic, acid, and/or other chemicals may be
injected into the water` by a metering pump. Sulfuric acid and sodium
hydroxide are 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
hypochlor to (calcium or sodium) or catalyzed hydrogen peroxide. Retention
time for each of the settling ponds range 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.
The FHP is aerated and is used to remove any persistent' oxygen demand or to
provide additional holdup capacity.; The FHP retention time is 1 to 2 days.
The capability is available for recirculation intea- or inter -basin. Flow
to the Catawba River may be by gravity at a rate of approximately 200 gpm
or be ,pumped at a rate of approximately 500 gpm. The pH of the discharge
from the WC system is adjusted by the automatically controlled addition o
carbon dioxide:
The WC system' accepts all nonradioactive plant waste except sanitary
sewage. The inputs can be contaminated with very low levels' of
radioactivity. Any discharges of radioactivity are monitored and'accounted
for, ;being regulated by the Nuclear Regulatory Commission (NRC). 'Inputs to
the system were described in the renewal' application submitted.December 28,
1988. An additional input being contemplated to begin it 1992 is the
landfill leachate.
Landfill. Leachate
The landfill will be constructed on Duke Power Company ,property across
Highway 73 from the station in 1992. The maximum working (active) area
of the landfill is currently estimated to be approximately 0 45 acres.

cells has a retention time of one day. The final cell is the settling cell
with a retention time of one day. The surface of this cell is kept slightly
agitated to minimize algal growth. If it becomes necessary to control algae
growth, an algicide, such as CUTRINE-PLUS, may be added to the lagoon. From
the final cell, the wastewater discharges to a chlorination device. After
passing through the chlorinators, a retention time in excess of 30 minutes
is provided by a contact chamber before being discharged to the WWCH.
The sewage lagoon has a multiple level discharge capability at 5, 6 1/2,
and 8 feet. At each of these different levels of operation, the lagoon is
able to provide a 5-day retention time for influent wastewater flow rates
of 40,000 gpd, 52,000 gpd, and 64,000 gpd, respectively.
Accumulated solids are removed from the lagoon approximately every 12 to 18
months to facilitate removal of non -biodegradable material and to optimize
the treatment process. The sludge bottoms are dewatered utilizing a filter
press or other suitable method. The solids are treated with lime and
disposed of in a State licensed landfill or landfarm. The filtrate is
returned to the sewage lagoon or is treated by neutralization and carbon
adsorption or other suitable methods when released directly to the WWCB. An
alternative method of sludge disposal is to tank it to a municipal sewage
treatment system.
The system was designed primarily to process domestic sewage from rest
rooms, showers, and lab drains from all buildings on the site as well as

domestic waste line. When operating, the photographic waste consist
of approximately 4 gpm water, 0.0059 gpm developer replenisher workii
solution, and 0.0297 gpm fixer and replenisher working solution. T]
developer replenisher working solution contains hydroquinonf
glutaraldehyde, potassium sulfite, and potassium acetate. The fix(
and replenisher working solution contains ammonium thiosulfate ai
sodium sulfate. Other developer replenisher working solutions and/(
fixer and replenisher working solutions with other constituents may I
substituted in the future. The developing process is operated
maximum of 30 hours per week (4.3 hours/day) but averages 6 hours p(
week (1.2 hours/day). Operation of the developing process results in
maximum of approximately 1041.2 gpd, with an average of 290.6 gpd,
