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-meihyl4, 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 appy 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 dinkrophenol, 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

General Information
Marshall Steam Station (MSS) is a coal-fired electric generating plant operated by
Duke Power Company. MSS is located on Lake Norman at NC 150 six miles west
of 1-77 in Catawba County near Terrell, North Carolina. The station derives its
name from E.C. Marshall, President of Duke Power from 1949 to 1953.
MSS is the second largest coal -burning station on the Duke system. The four unit
facility has consistently ranked as one of the most efficient coal plants in the
nation.
MSS Units 1 and 2, which began operation in 1965 and 1966, can generate
385,000 kilowatts of electricity each. Units 3 and 4.were completed in 1969 and
1970. Each has a generating capacity of 660,000 kilowatts. When operating at
full power, the station sends more than 2 million kilowatts of electricity over
transmission lines to homes, schools, businesses and industries of the Piedmont
Carolinas.
Duke Power created Lake Norman in 1963 when it dammed up the Catawba River
for Cowans Ford Hydroelectric Station. The lake supplies cooling water for MSS
and McGuire Nuclear Station located about 11 miles downstream.
An index to system descriptions and a line drawing showing the water flow through
MSS follow, indicating sources of intake water, operations contributing to the
effluent, and treatment provided. The approximated flows on the line drawing are
representative of station operation for the period of 1/93 - 9/94. Following the line
drawing is a brief narrative description of sources contributing to each outfall
effluent:.

L OUTFALL 007 - Once Through Non -Contact Cooling Water
Raw water from Lake Norman is passed through condensers and auxiliary
equipment on a ".once -through" basis to cool equipment and condense
'exhaust steam from the turbines. When MSS is operating at full power, it
has a design capacity to pump 1463.04 MGD of cooling water through a
network of tubes that runs through the condenser and selected heat
exchangers (e.g. turbine lube oil coolers, condensate coolers, miscellaneous
closed system coolers).. This raw water- in the condenser tubes absorbs heat
from a closed system .of highly purified exhaust steam from the turbines and
converts it back to water. The condensed exhaust steam is returned to the
boilers and recycled in this loop a number of times. The raw cooling water is
returned to the lake. No chemicals are added and only heat rejected from the
condensers and auxiliary equipment is absorbed, hence the term. "once
through, non -contact cooling water" is applied.
The condensers at MSS are cleaned mechanically. Normally, amertap balls
are cleaning the tubes on a continuous basis while the plant is operating.
Periodically, metal scrapers, plastic scrapers or rubber plugs are forced
through the tubes to rid them of scale or other deposits.
Units 1 and 2 at MSS have two condenser cooling water (CCW) pumps.
Units 3 and 4 have three CCW pumps. The capacities of these pumps are
listed in Table 1. Normal plant operation of the CCW pumps is based on
intake and discharge temperatures and unit load. To avoid a system trip that
would suddenly reduce the discharge flow at outfall 001, each unit is on an
independent system. This practice leads to a higher reliability factor for the
units and protection of aquatic .life taking refuge in the discharge canal during
cold weather.

A. Filter Backwash from Raw Water Intake Screening Device
(Permitted pursuant to G.S. 143-215.1(c) and Part III section I of
current permit.)
Raw water intake screens (32 total) at MSS are backwashed on an as
needed basis. Normally, the screens require backwashing once a
month for a period of approximately 5 minutes per screen. The
screens. (10'x20') are stationary type and are removed for cleaning.
The water required for backwashing is supplied by a low pressure
service pump with a design capacity of 300 gpm. Therefore, the
average flow of water used to backwash the screens is 0.002 MG.D.
Should it become necessary to backwash the screens on a continuous
basis the maximum flow .would be 0.43 MGD. This intake screen
backwash is discharged back into the station intake. The debris
collected on the screens consists mainly of twigs, leaves, and other
material indigenous to Lake Norman.

ll. OUTFALL 002 - Ash Basin Treated Effluent
The ash basin at MSS accommodates flows from two yard drain sumps, an
ash removal system, low volume wastes and non -point source storm water.'
Low volume waste sources include, but are not limited to: wastewater from
wet scrubber air pollution control systems, ion exchange water treatment
system, water treatment evaporator ,blowdown, laboratory and sampling
streams, boiler blowdown, floor drains, and recirculating house service water
systems.z Totalaverage-influentsfrom..these sources -combined -is}
approximatel_y_6...5_MG.D. At times, due to unit loads, rainfall, evaporation
and seepage of ash basin ponds, the amount of effluent may be different
than influent volumes.
A. Yard Drain Sumps
The yard drain sumps are large concrete structures that have four level
controlled pumps each that direct wastewater from the powerhouse
area to the ash basin. These pumps are operated on a rotating basis.
Usually two pumps are set so that one pump is primary and the other
is backup. After a preselected period the controls are changed so that
different pumps are utilized.
The yard drain sumps collect wastewater from many sources, such as,
the filtered water systemsanitary system; turbine arid -boiler room
The yard drain sumps also
,powerhou rs oe ofs and_pa eq. menu. Ground water from a foundation
drainage system under the track hopper is also intermittently
discharged to the yard drain sumps. Thexombin.ed_average_flo_w f_ m-,
pit erc stied to tthe yard drain sumps is approximately 1_.7 MGD,
,which`is pumped fo the,ash basin for pff-

1. Sanitary System
Sanitary waste from the plant is transported to a modified
package plant -via a gravity flow line. The sanitary waste from
the plant receives primary treatment in the package plant. In
the package plant, the volume of the tank provides a detention
time for the wastewater to be aerated with station service air.
Two submersible sump pumps, controlled by Level switches,
pump the water to the yard drainage sumps where the yard
drainage pumps transport the contents to the ash. basin for final
treatment. This system has been permitted to treat 0.014

treatment and secondary treatment component and will
eliminate the package plant near the intake structure of the
plant. An aerated lagoon will provide the primary treatment
with a 30 day retention time and have a total 'volume of
587,000 gallons. Effluent from the primary treatment system
will be polished by allowing additional residence time in the ash
basin which will perform the secondary treatment. The new
system will be designed for 6,:100 gpd (normal) and 13,500 gpd
(outage).
The power house lift station will be installed as a central
collection point to receive all the sanitary waste from MSS and
pump it to the aerated lagoon. The present lift stations serving
Monex and Units 3 and 4. will be upgraded. A gravity flow
sewer line will also be installed to connect the Electric Systems
Support (ESS) trailers to the plant sanitary system.

3. Boiler Room Sumps
The average flow pumped from the boiler room sumps directly
to the ash basin is approximately 1.3 MGD. The sources of
input to the boiler room sumps includes the -following:
a. Water Treatment System
The filtered water treatment system at MSS consists of a
clarifier, three gravity filters, two sets of activated carbon
filters, and two sets of dernineralizers. Wastewater and filter
media from the filtered water system and demineralizers are
drained to the, boiler room sumps which ultimately discharge to
the ash basin.
(1). Clarifier
The clarifier utilizes typical water treatment chemicals
such as, aluminum sulfate (alum), sodium hydroxide, and
chlorine for the primary treatment of raw water. The
sedimentation wastes collected in the clarifier consists of
solids that were suspended in the service water plus
aluminum hydroxide precipitate formed as a result of
adding aluminum sulfate (alum) and sodium hydroxide.
The quantity of alum used per year is approximately
6,000 gallons. The total amount of caustic is roughly
half the amount of alum. The average volume of water
required for desludging the clarifier is approximately
0.008 MGD. These sedimentation wastes along with
dilute water treatment chemicals and by-products are

piped to a floor drain which flows to the boiler room
sumps where they are pumped to the ash basin via the
yard drain sumps.
(2). Gravity Filters
There are three gravity filters composed of anthracite
(coal) which follow the clarifier in the water treatment
process. Normally, one of these filters is backwashed
each day. Approximately 0.007 MGD of backwash water
is required for each filter. This wastewater flows through
floor drains to .the boiler room sumps which pump to the
yard drain sumps. The anthracite filter is changed on an
as needed basis with the spent filter media,being sluiced
I
o the ash basin via the yard drain sumps.
(3). Activated Carbon Filters
The filtered water system includes two sets of activated
carbon filters. These filters are typically backwashed
_ once a month. The flow of water required to backwash
one of these filters is 500 gallons per day. The backwash
flows to the boiler room sumps and is pumped to the yard
drain sumps. Activated carbon is replaced on an as
needed basis with the spent carbon sluiced to the yard
drain sumps.
(4). Wastewater from demineralizer regeneration
Demineralizers at MSS consists of two sets of mixed -bed
cells which supply make-up water to the boilers and
other closed systems. Normal plant operation requires
that only one cell of each demineralizer set operates at
any one time., Each cell has a capacity of 225 gpm.
Supplemental Information

NC #0004987 Permit Renewal Application
December 15, 1994
Page 13 of 23
Each cell is regenerated approximately every other day.
Each year MSS will use an estimated 42,000 gallons of
50% caustic and 12,000 gallons of 93% sulfuric acid for
demineralizer regenerations. The dilute acid and caustic
are discharged from the cell simultaneously through the
same header for neutralization purposes. The
regeneration wastes flow to the boiler room sumps where
it is then pumped to the ash basin via the yard drain
sumps. The useful life of the resin varies and when
replacement is needed the spent resin is sluiced to the
ash basin.

k. Chemical makeup tanks and drum rinsate
(Intermittent rinse water containing small amounts of
aluminum sulfate, sodium hydroxide, hydrazine, and
ammonium hydroxide).
Boiler blowdown
Primarily when units 1 & 2 startup and until water
chemistry stabilizes the blowdown from these boilers is
allowed to flash in a blowdown tank. During startup, a
significant portion of this blowdown steam is vented to
the atmosphere. After water chemistry has stabilized,
blowdown venting is minimal and condensate flow is
small. Trace amounts of hydrazine, ammonia, and silica
oxide may be present in the condensate. The combined
condensate flow from blowdown amounts to an average
of approximately 0.002 MGD. This flow is routed to the
boiler .room sumps and then to the ash basin.
M. Chemical Cleaning of Boilers
or an -as -needed -basis: Tube inspections are done during
outages which indicate when cleaning needs scheduling.
Boilers #1 and #2 are controlled circulation boilers and
boilers #3 and #4 are supercritical boilers.
The volume of the boilers determines the quantity of
chemicals required for a cleaning. Boilers #1 and #2 each
have a -water -side volume of 51,600 gallons. The volume
of #3 and #4,boilers is 35,300 gallons each. The. total

4. Storm (Nater (see footnote 1 on page 7)
The yard drain sumps collect storm water runoff from a small
portion of the coal pile, rail access, hopper roofs and paving
around the powerhouse and pump it to the ash basin. A total of
14.7 acres drain to the yard drain sumps with an average daily
runoff estimated at 0.03 MGD. Thee average daily r_un_o_ff_is
,ealculated-based on an annual rainfall of 49-inches4with--l-.0--and
0:5run-off coefficients applied appropriately. Trace amounts of
oil and grease may be present in the first flush of storm water.
a. Yard Drain Sump #I
Yard drain sump #1 drainage area is approximately 7.2
acres including drainage from the plant yard and roofs of
miscellaneous structures (total area approximately
20,000 sf). The yard area includes coal handling
facilities, approximately one mile of rail and 0.25 miles of
access road. Approximately 25% of the area is paved or
roofed. An estimate of storm water drainage to this
sump is 0.013 MGD.
b. Yard Drain Sump #2
Yard drain sump #2 drainage area is approximately 7.5
acres including drainage from the plant yard and Units 1-3
roofs 0 61,600 A. The yard area includes approximately
1000 linear feet of plant access road and 1500 linear feet
of rail access. The yard also includes the electrostatic
precipitators, exhaust stacks and other miscellaneous ash
handling facilities. (storage silos, baghouses, ash lines,
etc.). The paved and roofed area represents
approximately 85% of the total drainage area. Trace
amounts of oil and grease may be present in the first
flush of storm water. An estimate of storm water
drainage to this sump is 0.014 MGD.

5. Induced Draft Fan Motor Bearing Cooling Water
Once through non -contact cooling water is supplied to the 16
bearings on the eight induced -draft (ID) fans to remove excess
heat. No chemicals are added to the once through raw lake
water. The rate of flow through the ID fan heat exchangers
which discharges to the yard drain sumps is approximately 0.08
MGD.
6. Track Hopper Sump
The track hopper sump collects ground water from a foundation
drain system underneath the track hopper. The flow is usually
intermittent, however the pump capacity is 100 gpm. On -a
daily basis it is estimated that the run time is only 50% which
would correspond to a flow'of 0.07 MGD to the yard drain
sumps.
7. Tunnel Un watering Sump
In the event that maintenance activities are needed in the intake
or discharge tunnels an unwatering sump is provided to remove
water from the tunnel(s). Raw water in the tunnels can be
removed by an unwatering pump which pumps to one of the
yard drain sumps which ultimately discharges to the ash basin.
8. Turbine
Bore sonic testing of turbine rotors is infrequent, once every 5
years. Demineralized water is mixed with a corrosion inhibitor,
e.g. Immunol 1228, at a ratio of 100 parts water to 1 part
inhibitor. The mixture is applied to the turbine rotors. The
-excess is drained and mixed with low volume wastewater and
discharged to the ash basin via the yard drain sumps...

B. Ash Removal System
MSS utilizes electrostatic precipitators as its air pollution control
devices. Under normal plant operations, the dry flyash captured in
these precipitators is collected in temporary storage silos for
subsequent disposal in a .permitted on-site landfill or for recycling in
off-site ash utilization projects. If the system that collects the dry
flyash is not operating, then the flyash can be sluiced to the ash basin.
Bottom ash from the boilers is usually water sluiced to holding cells for
recycling activities. Pyrites from the mills are water sluiced to the ash
basin. Approximately 2.5 MGD for bottom ash and pyrite removal is
pumped through large steel pipes (ash lines) directly to the ash basin.
Once through non -contact cooling water from the coal pulverizing mills
is discharged to the bottom ash hopper and pumped to the ash basin.
Electrostatic precipitators at MSS are normally cleaned by
mechanically rapping the wires and the plates inside the precipitator.
Before major precipitator work is performed they are cleaned by a
wash down. The wash water is pumped to the ash basin from the
yard drain sumps.
C. Storm Water (see footnote 1 on page 7)
Non -point sources of storm water to the ash basin .includes coal pile
runoff, a pond area of 82.3 acres and an upgradient watershed area of
1097.7 acres. The estimate for storm water run-off is based on forty-
nine (49) inches of rain per year with a 1.0 and 0.5 run-off coefficient
for the pond -area and upgradient watershed respectively. The average
non -point source storm_ water input for the ash basin is estimated at
2.3 MGD.

Once through non -contact cooling water is supplied to the Unit 4 induced
draft (ID) fan motor control house equipment to remove excess heat. No
chemicals are added to the once through raw lake water. The rate of flow
through the control equipment which discharges to Lake Norman is
approximately 0.2 MGD7.

V/. Marsha// Steam Station 316(a) Determination
Duke Power Company's operating experience during the past five years
under the thermal limitations imposed in NPDES Permit No. NC#0004987
substantiates EPA's 316(a) determination (May 1975) for Marshall that the
"thermal component of the discharge assures the protection and propagation
of shellfish, fish and wildlife in and on the receiving body of water."
In Duke's judgement the operating characteristics of the station have a
minimal effect on the aquatic environment of Lake Norman. The character of
the thermal discharge has not changed since the original 316(a)
determination. Accordingly, Duke Power requests that the thermal
limitations in the present permit be continued.
V//, Ash Basin Capacity
Part III Section R of the existing NPDES permit for MSS requires the
permittee to provide and maintain at all times a minimum free water volume
(between the top of the sediment level and the minimum discharge elevation)
equivalent to the sum of the maximum 24 hour plant discharges plus all
direct rainfall and all runoff flows to the pond resulting from a 10 year, 24
hour rainfall event, when using a runoff coefficient of 1.0.
Free water volume of ash basin at MSS:
