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

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

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

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 2c 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

1.0 General Information
Plant Allen utilizes waters from the Catawba River for condenser cooling and service water
requirements. A brief discussion of each discharge follows.All flows are based on historical data when
possible or pump design capacities and normal run-times.
2.0 Outfall Information
2.1 Outfall 001—Condenser Cooling Water(CCW)
The CCW system is a once-through, non-contact cooling water system that removes heat
rejected from the condensers and other selected heat exchangers and then discharges into the
South Fork River. Each of the 5 units at Plant Allen has two condenser cooling pumps.The
number of pumps used is dependent on unit load and intake temperatures with more pumps
running with higher loads and intake temperatures.
Units 1 and 2 share a common cooling water supply tunnel served by a total of 4 CCW pumps.
Units 3 and 4 also share a tunnel and 4 CCW pumps. Unit 5 has a separate tunnel and 2 CCW
pumps. The common tunnel design enables three pumps to give Units 1 and 2 or 3 and 4 the
equivalent of 1 Y2 pump operation. The 1'/: pump operation adds an economical range or
flexibility when units are on partial load and when intake water temperatures are minimal.
Condenser Cooling Water Pump Capacities
Unit No. 1-Pump GPM 1.5-Pump GPM 2-Pump GPM
1 55,500 74,800 83,500
2 55,500 74,800 83,500
3 83,000 111,200 126,000
4 83,000 1 111,200 126,000
5 83,000 1 1 126,000
Note: Maximum cooling flow 545,000 GPM
All condenser tubes at Plant Allen are cleaned manually with metal or rubber plugs. Mechanical
cleaning is required once a year for most units.A leak test is performed periodically on the
condenser tubes. If leaks are suspected,then one method used to temporarily stop small leaks
is to add sawdust to the CCW system, as previously approved by NC DENR.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 Asiatic Clam/Debris Filter Backwash
Water for the Unit 5 CCW water is filtered for any twigs, leaves, and other light debris,
which passed through the intake screens.Asiatic clams,which are common in Lake
Wylie and can clog the condenser tubes, are also captured in this filter. This filter is

backwashed once a week for 15 minutes. A maximum flow of 3000 GPD is realized. No
additives are in the backwash water. The twigs, leaves,clams and other light debris
collected in the debris filter are indigenous to the river and can be flushed back with no
harmful environmental consequences.
2.2 Outfall 002—Ash Basin
2.2.1 Stormwater run-off
Storm water run-off enters the ash basin from the ash basin's drainage area,the yard
drainage sump,the coal yard sump,the FGD storm water basin and the landfill leachate
sump. The powerhouse sump and the limestone storm water sump discharges its
rainfall run-off into the yard drainage sump.
2.2.2 Sanitary Wastes
Sanitary waste at Plant Allen is treated in a septic tank with the effluent from the septic
tank being discharged to the Ash Basin via the Coal Yard sump. Approximately 115
people are responsible for the load on this system.An average flow of 4850 GPD is
treated by the system.The drinking water is supplied by City of Belmont Utilities
Department.
2.2.3 Ash Sluice
Plant Allen has converted to a dry ash handling system. Ash collected in the
electrostatic precipitators is transported by compressed air to two silos where ash is
transferred to trucks for ultimate disposal in the newly constructed on-site landfill.Wet
sluicing is still utilized during times of dry system upset. Bottom ash sluicing to the basin
requires approximately 6.0 MGD.
Plant Allen presently has additional air pollution control systems installed on three units.
Use of these systems entails the use of low concentrations of sulfur compounds. These
systems aid in the collection of the ash in the electrostatic precipitators.
2.2.4 Recirculating Water System(RCW)
Plant Allen has 2 RCW systems: a chiller system and a pump cooling water system. Both
systems use the biocide Nalco H-550 or similar products. In addition,the corrosion
inhibitor Nalco CS-4710 or similar product is used. Generally,these systems are closed
loop in nature, but may need to be drained occasionally. All such water would enter the
floor drains and then be discharged to the ash basin.

2.2.5 Miscellaneous Waste Streams
2.2.5.1 Heat Exchanger Cleaning
Periodically, it may be necessary to clean the small heat exchangers with
polyacrylamide, polyacrylate, sodium laurylsulfate and tri-sodium phosphate.
All wastewater would be routed to the ash basin.
2.2.5.2 Condensate Polishers
Plant Allen utilizes condensate polishers which divert a portion of the normal
condensate (closed system)flow through one of two cells per unit. The
polishers provide filtration as well as ion exchange functions to remove or
substantially reduce dissolved solids and suspended matter present in the
condensate stream. The polishers require precoating with a combination of
anion and cation resin. To facilitate precoating, 125-150 mL of a solution of
polyacrylic acid (25%) is added to the precoat slurry. Upon resin exhaustion,the
precoat is removed from the filters by water/air blasting and flushed to the ash
basin via sumps.Condensate water is used to remove the exhausted precoat at
the rate of:
• Unit 1&2—1558 gal/precoat
• Units 3,4,&5—2090 gal/precoat
A total average waste flow of approximately 980 GPD to the ash basin is
realized.
2.2.5.3 Condenser Leakage Testing
Fluorescing Dye Method—Approximately 1 Ib.of a disodium fluorescing dye
added to 280,000 gals of demineralized water is used occasionally to test the
condensers for leakage. All wastewater from the testing would be routed to the
ash basin.
Sulfur Hexafluoride Method—Periodically,sulfur hexafluoride is injected into
the condenser tubes to locate condenser tube leaks. Sulfur hexafluoride is a
chemically inert, nonflammable, nontoxic gas with an extremely low water
solubility. It is estimated that 150 grams of sulfur hexafluoride would be used
during the leak detection process. Most of the sulfur hexafluoride would be
volatilized during the process.
2.2.5.4 FGD Stormwater Sump
Stormwater collected at FGD site including:the dry ash handling facility,gypsum
pile,WWTS area (not process water),stack,absorbers, switchgear building,

dewatering building, reagent prep building,and the control room area is routed
to a large stormwater collection basin prior to being pumped to the ash basin.
2.2.5.5 landfill leachate collection discharge
Industrial Solid Waste landfill (Permit No.36-12)is permitted to accept coal
combustion byproducts(fly ash, bottom ash,gypsum,WWTS filter press sludge
cake)consists of a double liner with leachate collection system. Collected
leachate is pumped to ash basin.
2.2.6 Ash Basin Treatment
Sulfuric Acid System—An acid injection system utilizing 93%sulfuric acid is operated as
needed to maintain pH level below 9.0 standard units.
Sodium Hydroxide System—A sodium hydroxide injection system utilizing 25%or 50%
sodium hydroxide operated as needed to maintain pH level above 6.0 standard units.
2.2.7 Yard Drain Sump
The yard drain sump is a large concrete structure that has three level controlled pumps,
which pump wastewater from Plant Allen to the ash basin. These pumps are operated
on a rotating basis. The combined average flow from all sources tied to the yard drain
sump is approximately 4.0 MGD. Listed below is a description of waste streams going to
the yard drain sump:
2.2.7.1 Boiler Room Sumps(Units 1-4)
The water which flows to the boiler room sumps originates from such sources as
floor wash water, boiler blowdown,water treatment waste,condensates,
equipment cooling water,sealing water and miscellaneous leakage(refer to the
attached schematic of water flow for individual flows). The effluent from the
units 1 through 4 boiler room sumps is flushed to the yard drain sump. The
effluent from the unit 5 boiler room sump is flushed to the power house sump,
which is then flushed to the yard drain sump.
2.2.7.2 Turbine Room Sumps
The turbine room sumps accommodate flows from floor washing, leakage,and
occasional condenser water box drainage. Effluent from units 1 through 5
turbine room sumps is flushed to the yard drain sump.

2.2.7.3 Limestone Unloading/Storage Area Sump
Limestone sump collects storm water from limestone unloading and storage
area and routes to YD sump via PH sump discharge line.
2.2.7.4 Power House Sump(Unit 5)
The wastes,which enter the floor drains at Plant Allen,accumulate in the boiler
room sumps and turbine room sumps. The water which flows to the boiler
room sumps originates from such sources as floor wash water, boiler
blowdown,water treatment waste,condensates,equipment cooling water,
sealing water and miscellaneous leakage. Effluent from the unit 5 boiler room
sump is routed to the powerhouse sump,which is then flushed to the yard drain
sump. This sump also receives storm water from various drains located on the
north end of the powerhouse.
2.2.8 Water Treatment System
The water treatment wastes consist of sedimentation,filter backwash, reverse osmosis
(RO)concentrate,demineralizer regeneration wastes and boiler blowdown. The make-
up water treatment system is comprised of a clarifier,two pressure filters,two activated
carbon filters, pre RO filters,a reverse osmosis unit and one set of demineralizers.
Make-up water is used in the boilers and closed cooling systems.
Clarifier:
The clarifier has an average production of 0.252 MGD.Caustic or ferric
sulfate/ferric chloride are used to affect precipitation and thus remove
suspended solids from the raw river water. Desludging of the clarifier takes
place approximately 8%of the unit run-time with an average volume of 2300
GPD going to the ash basin.
Pressure Filters:
There are two pressure filters which follow the clarifier in the water treatment
process. These filters are backwashed once per week with a waste flow of
11,000 gallons per backwash. Each pressure vessel will contain 84 ft3 of
anthracite, 50 ft3 of quartz,25 ft3 of garnet and 41 ft3 of garnet/quartz support
media. Each vessel will use product water to backwash at a rate of 750 gpm.
On average, both vessels are backwashed once per week. The contents of the
pressure filters will be changed out,as internal maintenance requires,and the
used filter medium will be sluiced to the ash basin.

Permittine Section

Activated Carbon Filters:
In addition to the pressure filters,there are two activated carbon filters. These
filters are backwashed twice per month. Approximately 30,000 gallons of water
are required to backwash each of these filters. The activated carbon filters are
composed of approximately 250 ft3 of granular activated carbon(coal). The
spent filter medium is changed out yearly and sluiced to the ash basin.
Reverse Osmosis(RO) Unit:
A RO unit is used to decrease the conductivity in the filtered water,thereby
increasing the efficiency of the demineralizers and reducing the amount of
chemical needed for demineralizer regeneration. During operation,the unit has
a continual blowdown of 60 gal/min,which is discharged to the ash basin. The
RO unit is cleaned on a quarterly basis with the waste going to the yard drains
and eventually the ash basin. During a cleaning,approximately 30 lbs of a
sulfamic acid cleaner along with 5 gallons of biocide, 2 liters of sodium
hydroxide,and 0.5 gallons of sodium lauryl sulfate is used
Demineralizer:
The demineralizer consists of two mixed-bed cells. Only one of these cells is
operated at any one time. The cell which is in operation is regenerated
approximately once every 7-14 days of operation. A regeneration requires 42
gallons of sulfuric acid (78-80%)and 150 gallons of 50%sodium hydroxide. An
average dilute waste chemical and rinse flow of 20,000 gal is realized. The
dilute acid and caustic are discharged to the floor drains simultaneously through
the same header for neutralization purposes. All regeneration wastes are
flushed to the ash basin. The demineralizer resin is changed out approximately
once every 10 years and the spent resin is sluiced to the ash basin.
Approximately 1 milliliter of the surfactant Triton CF-54 or similar product is
added to the new resin to improve separation.
Boiler Blowdown:
Each of the five boilers at Plant Allen blowdown at an average rate of
approximately 500 lbs.of steam per hour. The blowdown is allowed to flash in a
blowdown tank. Most of the blowdown is vented to the atmosphere with a
minimal amount of condensate discharged to the boiler room sump. The
average condensate flow to this sump is 0.004 MGD. Hydrazine is maintained at
a concentration of 25 ppb in the condensate system for deoxygenation. A
minute amount of hydrazine (<10 ppb) may be present in the condensate flow
to the boiler room sump.

2.2.9 Preheater Washes
Preheaters are backwashed with raw water on an as needed basis to remove ash and
corrosion products. There are 12 preheaters at Allen that would require approximately
100,000 gallons of backwash water each. The backwash water is routed to the ash basin
through the yard drain sump.
2.2.10 Laboratory Wastes
The plant chemistry and the FGD chemistry laboratories on-site perform a variety of
water analyses and routine sample collections. Therefore several chemicals are used in
the lab in small quantities for sample preservation, bottle rinsing,equipment
calibration,conductivity analyses,etc. The wastes are flushed down the sink and
discharged into the yard drain sump and then pumped to the ash basin. Some of the
laboratory chemicals are as follows:ammonia molybdate,acetic acid,ferric sulfate,
hydrochloric acid, monoethylamine, nitric acid and potassium hydroxide.
2.2.11 Selective Non-Catalytic Reduction(SNCR)
As part of the compliance with the North Carolina Clean Air Initiative (NCCAIR),Allen has
installed a urea-based "trim"Selective Non-Catalytic Reduction(SNCR)systems on all
five units. The trim SNCR systems are expected to reduce NOx emissions by
approximately 300.SNCR systems operate by injecting urea 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 on the fly ash in the electrostatic precipitators
and a small amount will 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.
2.2.12 Flue Gas Desulfurization(FGD)
A Wet Flue Gas Desulfurization (FGD) system has been installed at Allen for the
reduction of SO2 from the stack gas.The following provides a description of the FGD
system at Allen.
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 Allen collects the flue gas after it passes through the electrostatic
precipitator and routes the gas into the absorber tank. As the gas rises through the tank
to the outlet at the top,the gas passes through a spray header. A slurry 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 S03.
The SO3slurry falls to the bottom of the tank where a stream of air is injected to oxidize
the slurry to form gypsum(CaSO4 * 2H2O). The gypsum slurry is drawn off the

r
absorber tank and subsequently pumped to a vacuum belt filter. Part of the process
water from the FGD system is blown down in order to maintain the FGD water
chemistry within the FGD system specifications. This water is treated in a wastewater
treatment system that discharges to the ash basin via internal Outfall 005.
The FGD system has 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 onto the site by rail and 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 to a dewatering belt and then to a covered conveyor belt that
will carry it to a storage pile.The runoff from this area is also routed to the ash basin.
2.2.13 Seeps
There have been approximately nine (9)seeps identified associated with the ash basin
at the Allen Station. These seeps contribute a minimal amount of flow into Lake Wylie
and the Catawba River.
2.3 Outfall 002A—Coal Yard Sump Overflow
An overflow pipe that directs flow from the sump to the Catawba River was included in the
construction of the coal yard sump. This modification was implemented 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.
2.4 Outfall 0026—Powerhouse Sump Overflow
An overflow pipe that directs flow from the sump to the ground was included in the
construction of the powerhouse sump. This modification was implemented 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. If enough
water overflows,the waste water could potentially discharge into the Catawba River. Overflow
has not occurred during the last permit cycle.
2.5 Outfall 003—Misc Equipment Cooling&Seal Water
Outfall 003 discharges into the CCW discharge canal. The discharge consists of cooling water
from units 4 and 5 boiler feedpump hydraulic coupling coolers and other miscellaneous
equipment cooling. This water is once-through, non-contact cooling water withdrawn from the
service water system.
Approximately 10,000 gpd of bearing cooling water for the ash line booster pump is routed back
to the discharge canal via a stormwater outfall in the vicinity of outfall 003. The water is once
through, non-contact cooling water withdrawn from the service water system.

2.6 Outfall 004—Equipment Cooling&Intake Screen Backwash
2.6.1 Equipment Cooling Water
Cooling water for units 1,2&3 boiler feed pump hydraulic coupling coolers and other
miscellaneous equipment is discharged through outfall 004. This water is once-through,
non-contact water drawn from the service water system. In addition,water from a
vehicle rinse-down area is directed to this outfall. The rinse water contains no soaps or
other additives. Allen has also added a chiller system for comfort cooling that is a once-
through, non-contact cooling water system and discharges back to the river via outfall
004.
2.6.2 Intake Screen Backwash
The intake screens at Plant Allen are flushed on an "as needed" basis. Backwash usually
averages 2 hours per shift. The average volume required is 0.053 MGD. The large
debris floating on the river is caught on the parallel bar screens. This trash is collected
and disposed of in a landfill. The silt,twigs, leaves and other light debris collected on
the rotating screens are indigenous to the river and are therefore flushed back into the
river with no harmful environmental consequences.
2.7 (Internal) Outfall 005—WWTS Effluent Discharge
FGD purge water is routed to a WWTS consisting of a physical-chemical process designed to
precipitate heavy metals and remove suspended solids. The clarified product water is routed to
a series of bioreactors designed for selenium and nitrate removal. The bioreactor product water
is discharged to the ash basin via Outfall 005.
3.0 Hazardous and Toxic Substances
3.1 Hazardous and Toxic Substances Table 2c-3
At Plant Allen,the potential for toxic and hazardous substances being discharged is very low.
In reference to Item V-D of Form 2-C,the substances identified under Table @c-3 that may
be in the discharge are as follows: Acetaldehyde,Asbestos, Butyl Acetate,Cyclohexane,
Diuron, Epichlorohydrin, Formaldehyde, Monoethyl Amine, Propylene Oxide, Pyrethrins,
Vinyl Acetate,and Xylene.
Other- During the course of the year products such as commercial cleaners and laboratory
reagents may be purchased which contain low levels of a substance found in Table 2c-3. It is
not anticipated that these products will impact the ash basin's capacity to comply with
existing toxicity limits,since their concentrations are extremely low.

3.2 40 CFR 117 and CERCLA Hazardous Substances
The following table identifies hazardous substances located on-site that may be released to
the ash basin during a spill in quantities equal to or greater than the reportable quantity
(RQ) levels as referenced in 40 CFR 117,302 and 355. This list is provided under 40 CFR 117
and the Comprehensive Environmental Response Compensation and Liability Act(CERCLA).
These values below represent the maximum quantities onsite that could be released at one
time and sent to the ash basin. They do not reflect quantities that are discharged through
typical use.
