PART C-If you are a primary Industry and this outfall contains process wastewater,refer to Table 2c-2 1n the instructions to determine which of the GC/MS fractions you must test for.Mark"X"In
column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals,cyanides,and total phenols.If you are not required to mark column 2-a(secondary industries,
nonprocess wastewater outfalls,and nonrequired GC/MS fractions),mark"X"in column 2-b for each pollutant you know or have reason to believe is present.Mark"X"in column 2-c for each
pollutant you believe is absent.If you mark column 2a for any pollutant,you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant,you
must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater.If you mark column 2b for
acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these pollutants which you know or have reason to
believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or briefly describe the
reasons the pollutant is expected to be discharged.Note that there are 7 pages to this part;please review each carefully.Complete one table(all 7 pages)for each outfall.See instructions
for additional details and requirements.

Supplemental Information
For
Marshall Steam Station
NPDES Permit No. NC0004987
October 2014

1.0 General Information
Marshall Steam Station (MSS) is located on NC Highway 150, six miles west of 1-77 in Catawba
County on Lake Norman near Terrell, North Carolina. MSS consists of four coal-fired steam electric
generating units. Units 1 and 2 can generate 380,000 kilowatts (net) of electricity each and units 3
and 4 have the capacity to generate 660,000 kilowatts (net) of electricity each.
A brief discussion of the individual waste streams follows.
2.0 Outfall Information
2.1 Outfall 001 - Condenser Cooling Water(CCW) Units 1-4
The CCW system is a once through non-contact cooling water system, which condenses
steam from the condensers and other selected heat exchangers. When MSS is operating at
full power, it has a design capacity to pump 1463 MGD (1,016,000 GPM) of cooling water
through a network of tubes that runs through the condenser and selected heat exchangers.
The raw cooling water is returned to the lake. No biocides or other chemicals are used in the
condenser cooling water.
Units 1 and 2 have two CCW pumps per unit and Units 3 and 4 have three CCW pumps per
unit with the following maximum flow capacities:
Unit No. 1-Pump 2-Pump 3-Pump
GPM GPM GPM
1 126,000 190,000 -
2 126,000 190,000 -
3 150,000 253,000 318,000
4 150,000 253,000 318,000
The operational schedule for these pumps is dependent on the intake water temperature and
on the unit loads. Depending on the electrical demand, pumps are operated to maximize MSS
efficiency and to assure balanced and indigenous populations are maintained in Lake Norman.
Each unit is on an independent system to avoid a system trip that would suddenly reduce the
discharge flow at outfall 001. 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. Flow
recorded on the monthly Discharge Monitoring Reports is based on CCW pump run times.
The condensers are mechanically cleaned. Normally, amertap balls are cleaning the tubes on
a continuous basis while the plant is operating. Periodically, after the condenser is drained,
metal scrapers, plastic scrapers or rubber plugs are forced through the tubes to rid them of
scale or other deposits. The condenser tubes may also be tested for leaks, as needed. A leak
test can be conducted in approximately two to three hours per unit with usually no more than
six injections of tracer gas (i.e., sulfur hexaflouride, helium, etc) each within approximately a 30
second period and/or checked with fluorescent dye. The dye is added to the condensate water
and put on the outside of the condenser tubes. During the test, if fluorescent water does leak
into the tubes, this discharge indicates a leak does exist in the condenser tubing. The levels of
gas or dye that might be discharged would be well below any levels of aquatic biological
toxicity concerns. If leaks are detected, then one method used to temporarily stop small leaks
is to add sawdust to the CCW system, as previously approved by NCDENR. The sawdust is

added at amounts that will plug the leaks and not result in an environmental impact. This is a
temporary measure until the unit can come off-line so the leaks can be permanently repaired.
2.1.1 Intake Screen Washing Manually by Removing Screens
The intake screens (32 total) are washed on an as needed basis. Normally, the screens
require washing once a month for a period of approximately 5 minutes per screen. The
screens (10 ft x 20 ft) are stationary type and are removed for cleaning. A low-pressure
pump supplies the raw water required for washing with a design capacity of 300 gpm.
Therefore, the average flow of water used to backwash the screens is 0.002 MGD.
Should it become necessary to backwash the screens on a continuous basis the
maximum flow would be 0.43 MGD per screen. The debris collected on the screens
consists of twigs, leaves, and other material indigenous to Lake Norman and is removed
and properly disposed. The intake screen backwash water drains back to the station
intake cove without any adverse environmental impact.
2.2 Outfall 002 - Ash Basin
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. Total average influent from these sources combined is approximately 8.3 MGD. At
times, due to unit loads, rainfall, evaporation and seepage of ash basin ponds, the amount of
effluent may be different than influent volumes.
2.2.1 Yard-Drain Sumps
The yard-drain sumps are concrete structures having 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 selected 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
system, turbine and boiler room sumps, miscellaneous equipment cooling water,
foundation drainage, low volume wastes, and tunnel unwatering. The yard-drain sumps
also collect some storm water runoff from the coal pile, rail access, and powerhouse
roofs and pavement. Ground water from a foundation drainage system under the track
hopper is also intermittently discharged to the yard-drain sumps. The combined
average flow from all sources tied to the yard-drain sumps is approximately 2.43 MGD,
which is pumped to the ash basin for physical and biological treatment.
2.2.2 Turbine Room Sumps
The turbine room sumps collect approximately 0.35 MGD of wastewater. This
wastewater comes from non-contact cooling water (from Units 1 & 2 boiler feedpump
turbine lube oil coolers) and floor drains. Floor drains contain boiler blowdown, leakage
from seals, equipment cooling water, condensate from the feedwater system, low
volume wastewater, boiler room sump overflow, emergency fire fighting water, general
mechanical maintenance activities, miscellaneous plant wastes and area washdown
water.

2.2.3 Boiler Room Sumps
The average flow pumped from the boiler room sumps directly to the ash basin is
approximately 1.55 MGD. The sources of input to the boiler room sumps include the
following:
2.2.3.1 Water Treatment System
The MSS make-up water treatment system is comprised of a clarifier, three
gravity filters, two sets of activated carbon filters, a reverse osmosis system and
two sets of demineralizers. The water treatment wastes consist of floc and
sedimentation, filter backwash, reverse osmosis concentrate reject and cleaning
wastes, and demineralizer regeneration wastes. Water processed through this
system is supplied to the boilers to generate steam to tum the turbines. On
occasion a vendor may be used with a mobile water treatment unit to augment
the facility water treatment capacity. Any vendor will use traditional water
treatment methods, chemicals, and disposal methods generally described below.
This wastewater is drained to the boiler room sump, which ultimately discharges
to the ash basin.
Clarifier.-
The
larifier.The clarifier utilizes typical water treatment chemicals such as, Ferric sulfate (),
sodium hydroxide, and calcium hypochlorite 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 Ferric precipitate formed as a result of
adding Ferric sulfate () and sodium hydroxide. The quantity of Ferric Sulfate
used per year is approximately 14,000 gallons. The total amount of caustic is
roughly one quarter the amount of Ferric Sulfate 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 sump.
Gravity Filters:
There are three gravity filters composed of anthracite (coal) which follow the
clarifier in the water treatment process. They are used for removal of colloidal
material and are backwashed as necessary, dependent upon the level of solids
in the water. Normally, one of these filters is backwashed each day.
Approximately 0.007 MGD of backwash water is required for each filter. This
flow is discharged to the floor drains to the boiler room sump, which pumps to the
yard-drain sump. The gravity filter medium is changed out on an as-needed
basis with the spent filter media being landfilled.
Activated Carbon Filters:
Two activated carbon filters remove organics and the chlorine that is injected into
the clarifier. These filters are typically backwashed approximately once a week.
The flow of water required to backwash one of these filters is 20,000 gallons per
day. The wash water flows to the boiler room sump and is pumped to the yard-
drain sump. Activated carbon is replaced on an as needed basis with the spent
carbon sluiced to the ash basin.

Reverse Osmosis System
There is a two stage Reverse Osmosis (RO) system which processes
approximately 535 gallons per minute of filtered water. Approximately 400 gpm
of permeate water is produced and flows to the permeate water storage tank.
Approximately 135 gpm of concentrate water is produced which flows to the
boiler room sump and ultimately the ash basin via the yard drain sump. Water
from the permeate tank is pumped to the demineralizers as supply water.
The RO system is cleaned approximately twice per year using a dilute low pH
cleaner(sulfonic acid/citric acid), biocide (Trisep Tristat 110), and a high pH
cleaner(sodium hydroxide/sodium lauryl sulfate).
Demineralizers:
Demineralizers at MSS consist 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 operate at any one time.
Each cell has a capacity of 225 gpm.
Each cell is regenerated approximately every four weeks. Each year MSS will
use an estimated 8,000 gallons of 50% caustic and 2,500 gallons 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
pumped to the ash basin via the yard-drain sump. The useful life of the resin
varies and when replaced spent resin is sluiced to the ash basin.
2.2.3.2 Miscellaneous Waste Streams
• Closed system drainage, cleanings, testing containing corrosion inhibitors
(Calgon CS), biocides (Calgon H-550 and H 7330), cleanings'! (small heat
exchangers), dispersant (polyacrylamide), wetting agent (sodium lauryl
sulfate), detergent (tri-sodium phosphate), and leak testing (disodium
fluorescing dye).
• Turbine room sump overflow
• Boiler seal water(trace oil and grease)
• Miscellaneous system leakages (small leaks from pump packings and seals,
valve seals, pipe connections)
• Moisture separators on air compressor precipitators
• Floor wash water
• Emergency fire fighting water
• Pyrite (ash) removal system overflow
• Low Volume Wastewater.
2.2.3.3 Chemical makeup tanks and drums rinsate
Intermittent rinse water containing small amounts of Ferric sulfate, sodium
hydroxide, hydrazine, ammonium hydroxide.
2.2.3.4 Boiler blowdown
To date small closed system cleanings (e.g. heat exchangers) have not used these chemicals, reserved for
future use.

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 sump and then to the ash basin.
2.2.3.5 Boiler Cleaning
Boilers #1, #2, #3 and #4 at MSS are chemically cleaned on an as needed basis.
Tube inspections are performed 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 wastes produced from a boiler chemical
cleaning are pumped to the ash basin.
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 volume of dilute waste
chemicals, including rinses, discharged from #1 or #2 boilers during a chemical
cleaning is 580,000 gallons. The total volume of dilute waste chemicals drained
from #3 or #4 amounts to 320,000 gallons. This dilute wastewater is drained
through temporary piping to permanent ash removal piping where flow goes to
the ash basin. The chemicals and approximate amounts for each cleaning are
listed below.
CLEANING CHEMICALS AMOUNT USED PER UNIT
Alkaline Boilouts —(only after major boiler tube work)
Boiler#1 or#2 Boiler#3 or#4
Soda Ash 4400 Ib NA
Trisodium Phosphate NA 3000 Ib
Triton X-100* Detergent (0.05%) 25 gal 18 gal
Antifoam Agent (0.025%) 13 gal 9 gal
* or equivalent detergent
EDTA Boiler Chemical Cleaning
Boiler#1 or#2 Boiler#3 or#4
Tetra-ammonium EDTA (38%) 11000 gal NA
Antifoam Agent 15 gal 10 gal
Ammonium Hydroxide (260Be') NA 1,400 gal
Di-ammonium EDTA (44.5%) NA 6,000 gal
Rodine 2002 (corrosion inhibitor) 300 gal 240 gal
Regardless of the method used for cleaning, no waste water will be discharged to
the ash basin, rather all cleaning waste waters will either be evaporated in the
boiler or collected and transported off-site for proper treatment and disposal.

2.2.4 Stormwater Runoff
The ash basin collects/receives flows from the yard drainage basins, ash removal lines
and rainfall run-off from the basin watershed area. Some of the flows pumped into the
ash basin from the yard drains include roof runoff, stormwater discharge from
transformer containments, stormwater discharge fom fuel oil containments, stormwater
from the FGD facility, rail lines, coal handling facilities, chemical storage and
miscellaneous plant equipment. Details of storm water the runoff that flows into the ash
basin via gravity are described in section 2.2.15.
2.2.5 Induced Draft Fan Motor Bearing Cooling Water
Once through non-contact cooling water is supplied to eight induced draft (ID)fan motor
bearings 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 that discharges to the yard-
drain sumps is approximately 0.08 MGD, which is pumped to the ash basin.
2.2.6 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, which is pumped to
the ash basin.
2.2.7 CCW Tunnel-Unwatering 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 tunnels. Raw water in the
tunnels can be pumped to the yard-drain sumps that ultimately discharge to the ash
basin.
2.2.8 Turbine Non-Destructive Testing
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.
2.2.9 Ash Sluice
MSS utilizes electrostatic precipitators as its air pollution control devices. Under normal
plant operations, the dry fly ash captured in these precipitators is collected in temporary
storage silos for subsequent disposal in a permitted on-site structural fill or for recycling
in off-site ash utilization projects. If the system that collects the dry fly ash is not
operating, the fly ash can be sluiced to the ash basin. Bottom ash from the boilers is
usually sluiced with water to a holding cell for recycling activities. Pyrites from the mills
are sluiced with water to an ash basin settling-cell. Approximately 3.21 MGD of
fly/bottom ash and pyrite sluice is pumped through large steel pipes (ash lines) directly
to the ash basin settling-cell. Once through non-contact cooling water from the coal
pulverizing mill is discharged to the bottom ash hopper and pumped to the ash basin.
Electrostatic precipitators at MSS are normally cleaned by mechanically vibrating the
wires and rapping 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 sump.

2.2.10 Sanitary Waste
A sanitary waste treatment system is operational and consists of an aerated basin that
provides treatment with a 30-day retention time and has a total volume of 587,000
gallons. Effluent from the aerated basin is polished further through additional residence
time in the ash basin. The system is designed for 6100 gpd (normal) and 13,500 gpd
(outage).
The powerhouse lift station was installed as a central collection point to receive all the
sanitary waste from MSS and pump it to the aerated basin.
The sanitary system accommodates wastewater flow from the following sources:
• General plant sanitary wastewater
• Vendor facilities sanitary wastewater
• Laboratory drains (Small amounts of laboratory chemicals used to test
wastewater effluents and high purity boiler water, see the following table for
non-hazardous substance).
Substance Quantity Location
2-Propanol 4 gal. Lab/Warehouse
Glycerin 4 gal. Lab/Warehouse
Indigo carmine 0.3 Ib Lab
Dimeth laminobenzaldeh de 0.22 lbs Lab
Table values represents typical quantities on-site at any given time and do not
necessarily reflect quantities discharged.
2.2.11 Ash Silo Storm Water Sump
A ash silo system has been constructed for dry handling of the ash. This system
includes a sump for collection of rainfall runoff and washdown of the silo area, which is
pumped to the ash basin. This sump's drainage area is approximately 1 acre. Overall,
this will be a minimal input to the ash basin.
2.2.12 Wastewater from Plant Additions
2.2.12.1 Selective Non-Catalytic Reduction (SNCR)
As part of the compliance with the North Carolina Clean Air Initiative (NCCAIR),
Marshall installed urea based "trim" Selective Non-Catalytic Reduction (SNCR)
systems on units 1, 2, and 4. The trim SNCR systems are expected to reduce
NOx emissions by approximately 20%. SNCR systems operate by injecting urea
liquor into the upper section of the boiler where a chemical reaction occurs to
reduce the NOx to water and nitrogen. Some residual ammonia will be collected
in the fly ash from the electrostatic precipitators. The majority of this ammonia will
stay with the ash as it is handled dry but a small amount may be carried to the
ash basin. However, the operation of the SNCR system is not expected to
require additional treatment capabilities to ensure compliance with NPDES
permit limits. Marshall units 1, 2, and 4 currently are using this technology to
reduce NOx whereas unit 3 operates a Selective Catalytic Reduction (SCR)
system.

2.2.12.2 Selective Catalytic Reduction (SCR)
As part of the compliance with the North Carolina Clean Air Initiative (NCCAIR),
Marshall has replaced unit 3's SNCR with a more efficient Selective Catalytic
Reduction (SCR) system, capable of reducing NOx by approximately 90%. This
SCR utilizes a urea to ammonia (U2A) which converts the urea liquor into an
ammonia gas, external to the boiler in a hydrolyzer. The hydrolyzer contains
approximately 1000 gallons of urea while in operation and periodic blowdowns
occur to flush out sediment in the bottom of each hydrolzer. Small quantities of
urea will be discharged into the ash basin from the blowdown process. Roughly,
10 gallons a week is discarded during the blowdown process and is collected in
the ash basin. Similar to the SNCR, the SCR will also result in small traces of
ammonia in the fly ash that is collected from the electrostatic precipitators. The
majority of this ammonia will remain with the ash as it is handled dry but a small
amount may be carried to the ash basin. However, the operation of the SCR
system is not expected to require additional treatment capabilities to ensure
compliance with NPDES permit limits.
2.2.12.3 Flue Gas Desulfurization (FGD)
The installation of a Wet Flue Gas Desulfurization (FGD) system was completed
in 2006 at Marshall for Unit 4. The remaining units FGD systems were
completed in 2007. The FGD is an air pollution control system that removes SO2
from the flue gas system. In a Wet Scrubber system the SO2 component of the
flue gas produced from the coal combustion process is removed by reaction with
limestone-water slurry. The particular system used at Marshall will collect the
flue gas after it passes through the electrostatic precipitator and route the gas
into the lower end of a vertical tank. As the gas rises through the tank to the
outlet at the top, the gas passes through a spray header. An atomized slung of
water and limestone droplets is continually sprayed through this header into the
stream of flue gas. The SO2 in the flue gas reacts with the calcium in the
limestone and produces SO3. The SO3 slurry falls to the bottom of the tank
where a stream of air is injected to oxidize the slung to form gypsum
(CaSO4•H2O). The gypsum slurry is drawn off the tank to a hydrocyclone and
subsequently routed to a vacuum belt filter. The liquid waste from this process
will be treated as wastewater in the constructed treatment wetlands. The effluent
from the CTW discharges to the ash basin (via NPDES Intemal Outfall 004).
The FGD system requires a material handling system that supplies limestone to
the scrubber and a gypsum storage area for the gypsum removed from the
process. The limestone comes into the site by rail and is stored in an area near
the coal pile. It is then transferred to the FGD site via a covered conveyor.
Runoff from the storage area is routed to the ash basin. The gypsum is routed
from the FGD tank via a covered conveyor belt that carries it to a storage pile.
The runoff from this area is also routed to the ash basin.
The FGD system also requires a gypsum landfill. The FGD landfill is located
west of the Marshall Ash Basin. The runoff and leachate from this landfill is
routed to the ash basin. FGD residue material that is not suitable for beneficial
use as wallboard will be placed in the landfill. In addition to this material, material
is periodically removed from the clarifier stage of the wastewater treatment

system and placed in the landfill. The landfill footprint contains approximately
20.64 acres. The landfill is permitted to receive asbestos from Duke Genergy
Carolinas, facilities, generated gypsum from the Allen, Marshall and Cliffside
Stations, generated clarifier sludge from the Allen, Marshall and Cliffside Sations
as well as the following wastes generated soly from the Marshall Station: fly and
bottom ash, C&D debris, pyrites, waste limestone material, land clearing and
inert debris, boiler slag, mill regects, sand blast material and coal waste.
The FGD residue is conveyed to the landfill site by truck, where the material is
spread and compacted. The landfill began receiving FGD residue in the fall of
2006. The volumetric capacity of the landfill is 2.19 million yd3- Duke Energy is
exploring other beneficial uses for the FGD residue (gypsum). If these options
are determined to be viable, the FGD residue meeting the material requirements
for the beneficial uses will not be disposed in the landfill.
2.2.13 Seepage
MSS has identified two seeps in the vicinity of the of the ash basin dam. These
seeps contribute a small amount of water to Lake Norman.
2.2.14 Industrial Waste landfill Leachate
Construction of an industrial waste landfill is scheduled to begin in early 2010.
Landfill operation is slated for late 2010. Fly ash, FGD gypsum and clarifier
sludge will be disposed in this landfill. Landfill runoff and leachate will be routed
to the ash basin for treatment.
2.2.15 Stormwater Gravity Drains to the Ash Basin
Marshall Steam Station has several non-stormwater discharge drainage areas
that drain via gravity flow into the ash settling basin, or discharge into station
sumps that subsequently pump to the ash settling basin. These aere addressed
were addressed in Section 2.2.4. All of the areas north of the primary coal
delivery rail lines gravity drain to the ash settling basin. The following is a
summary of the stormwater that gavity drains to the ash basin:
2.2.15.1 FGD Gypsum Radial Stacker
This drainage area includes the FGD gypsum radial stacker operation and
portions of an adjacent soil borrow area. Stormwater runoff from this area
enters a detention basin before discharging into a tributary of the ash
settling basin to the north.
2.2.15.2 Soil Borrow Area
This drainage area includes the remaining portions of the soil borrow area.
Stormwater runoff from this area enters a detention basin on the west side
of the drainage area before discharging into a small creek that flows to the
ash settling basin.
2.2.15.3 Drainage Area 15— FGD Landfill
This drainage area includes the FGD residue landfill. Stormwater runoff
from this area enters a detention basin at the southeastern edge of the
landfill and is subsequently piped via gravity flow to the ash settling basin.

This landfill also includes FGD wastewater treatment sludge, asbestos,
flyash, bottom ash, mill rejects, and construction and demolition debris.
2.2.15.4 Coal Pile
This drainage area is comprised entirely of the station coal storage pile.
Stormwater runoff from this area enters perimeter ditches that discharge
into the ash basin.
2.2.15.5 Sanitary Wastewater Lagoon
This drainage area is comprised of the sanitary wastewater treatment
lagoon and surrounding area. Stormwater runoff discharges into the ash
basin to the north.
2.2.15.6 FGD Constructed Wetland Treatment System
This drainage area is comprised of the constructed wetland treatment
system (CWTS) designed to treat wastewater from the FGD solid removal
wastewater treatment system. Stormwater runoff from the CWTS area
flows into the adjacent ash settling basin.
2.2.15.7 Bottom Ash Operation and Pyrite Operation
This drainage area includes the bottom ash operation and recovery of coal
from pyrites. All stormwater runoff from this area is routed via ditches into
the ash settling basin.
2.2.15.8 Closed Ash Landfill
This drainage area includes the closed and capped ash landfill. All
stormwater runoff from this area is routed via ditches into the ash settling
basin.
2.2.15.9 Beneficial Structural Fill
This drainage area includes the active beneficial ash structural fill. All
stormwater runoff from this area is routed via ditches into the ash settling
basin.
2.3 Outfalls 002A and 002B - Yard-Drain Sump Emergency Overflow
An overflow pipe that could direct flow from the sump to Lake Norman was included in the
construction of the two yard sumps. This modification was performed to prevent submergence
and damage of the pump motors within the sumps in the event that all pumps failed or
redundant power supply lines could not be restored in a timely manner. Outfall 002A has
overflowed five times between April 2007 and March 2009. Outfall 002B has overflowed two
times between April 2007 and March 2009. Observations and monitoring of effluent during
these events have indicated no noticeable impact to water quality. No sanitary waste is routed
through the yard-drain sumps.
2.4 Outfall 003 - Unit 4 ID Fan Control House Cooling Water
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 flow rate through the control equipment that discharges to Lake Norman
is approximately 0.2 MGD.

2.5 Internal Outfall 004— Treated FGD Wet Scrubber Wastewater
The wastewater from the FGD system is conveyed to the wastewater solids removal system,
which discharges into the mixed equalization tank. The wastewater contained in the
equalization tank is conveyed to the flocculating clarifier which is utilized as the liquid/solids
separation device. Polymer may be injected to aid in the settling process. Clarified effluent is
conveyed to the Constructed Treatment Wetlands (CTW) supply tank.
Settled solids are removed from the clarifier by the operating sludge transfer pump and
conveyed to the mixed sludge holding tank and dewatered by the filter presses. Dewatered
cake from the filter presses is ultimately landfilled. Filtrate from the dewatering process is
conveyed to the equalization tank for reprocessing.
The CTW system receives wastewater from the clarifier unit where it enters two equalization
basins, each with a 24-hour hydraulic retention time (HRT) for cooling, mixing, concentration
equalization, and settling of solids. Water from the equalization basins is normally split into 6
flows then to three equal flows, each entering a treatment train consisting of two 1.28 acre
wetland cells (36 hour HRT), a 0.24 acre rock filter and a 1.67 acre final wetland cell (64 hour
HRT). Total area of treatment is approximately 15 acres with a normal HRT of 8 days based
on average projected flows. The CTW system will treat an average flow of 1.2 and a peak flow
of 1.4 MGD.
