Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: clear colorless to yellow liquid.
Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. May be fatal if mist inhaled.
Strong inorganic acid mists containing sulfuric acid may cause cancer. Concentrated sulfuric acid reacts violently with
water and many other substances under certain conditions. May cause lung damage. Hygroscopic (absorbs moisture
from the air). Corrosive to metal.
Target Organs: Lungs, teeth, eyes, skin.
Potential Health Effects
Eye: Causes severe eye burns. May cause irreversible eye injury. May cause blindness. May cause permanent corneal
opacification. The severity of injury depends on the concentration of the solution and the duration of exposure.
Skin: Causes skin burns. The severity of injury depends on the concentration of the solution and the duration of
exposure.
Ingestion: May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns.
Inhalation: May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing,
wheezing, shortness of breath and pulmonary edema. Causes chemical burns to the respiratory tract. Inhalation may
be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary
edema. Because its vapor pressure is negligible, it exists in the air only as a mist or spray. Exposure may impair lung

/function and cause mucostasis (reduced mucous clearance).
Chronic: Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated inhalation may cause
nosebleeds, nasal congestion, erosion of the teeth, perforation of the nasal septum, chest pain and bronchitis.
Prolonged or repeated eye contact may cause conjunctivitis. Effects may be delayed. Workers chronically exposed to
sulfuric acid mists may show various lesions of the skin, tracheobronchitis, stomatitis, conjunctivitis, or gastritis.
Occupational exposure to strong inorganic acid mists containing sulfuric acid is carcinogenic to humans.
Section 4 - First Aid Measures
Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid
immediately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a
cupful of water. Never give anything by mouth to an unconscious person.
Inhalation: POISON material. If inhaled, get medical aid immediately. Remove victim to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Monitor arterial blood gases, chest x-ray, and pulmonary function tests if respiratory tract
irritation or respiratory depression is evident. Treat dermal irritation or burns with standard topical therapy. Effects
may be delayed. Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
Section 5 - Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH
(approved or equivalent), and full protective gear. Use water spray to keep fire-exposed containers cool. Substance is
noncombustible. Contact with water can cause violent liberation of heat and splattering of the material. Contact with
metals may evolve flammable hydrogen gas. Runoff from fire control or dilution water may cause pollution. Approach
fire from upwind to avoid hazardous vapors and toxic decomposition products. Strong dehydrating agent, which may
cause ignition of finely divided materials on contact. Oxides of sulfur may be produced in fire.
Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. Do NOT get water inside
containers. If water is used, care should be taken, since it can generate heat and cause spattering if applied directly
to sulfuric acid.
Flash Point: Not applicable.
Autoignition Temperature: Not available.

Upper: Not available.
NFPA Rating: (estimated) Health: 3; Flammability: 0; Instability: 2; Special Hazard: -W-
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Carefully scoop up and place into appropriate disposal
container. Provide ventilation. Do not get water inside containers. Cover with dry earth, dry sand, or other non-
combustible material followed with plastic sheet to minimize spreading and contact with water.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow
water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Discard contaminated shoes. Use only with adequate ventilation. Do not breathe spray or mist. Do not

Carcinogenicity:
CAS# 7664-93-9:
• ACGIH: A2 - Suspected Human Carcinogen (contained in strong inorganic acid mists)
• California: carcinogen, initial date 3/14/03 (listed as Strong inorganic acid mists containing sulfuric acid).
• NTP: Known carcinogen (listed as Strong inorganic acid mists containing s).
• IARC: Group 1 carcinogen
Epidemiology: Workers exposed to industrial sulfuric acid mist showed a statistical increase in laryngeal cancer. This
suggests a possible relationship between carcinogenesis and inhalation of sulfuric acid mist.
Teratogenicity: Sulfuric acid was not teratogenic in mice and rabbits, but was slightly embryotoxic in rabbits (a
minor, rare skeletal variation). The animals were exposed to 5 and 20 mg/m3 for 7 hr/day throughout pregnancy.
Slight maternal toxicity was present at the highest dose in both species.
Reproductive Effects: No information found
Mutagenicity: There are no mutagenicity studies specifically of sulfuric acid. However, there are established effects
of reduced pH in mutagenicity testing, as would be caused by sulfuric acid. These effects are an artifact of low pH and
are not necessarily due to biological effects of sulfuric acid itself.
Neurotoxicity: No information found

Note: Feed System Acceptable Materials
Utilize plastic piping and fittings where possible on neat polymer feed lines.Where strength is needed,
316 SS pumps, valves, etc. can be used. However, these components, especially pump internals, will
have a reduced life span. Be sure to routinely inspect all 316 SS components for signs of corrosion and
to utilize check valves with Teflon or epoxy-coated springs.
DOSAGE AND FEEDING
CORE SHELL 71301 should be fed via a closed feed system. A closed feed system is defined as a
system in which fluid is moved from a closed storage vessel into a treated media without exposure to
the atmosphere (except through normal venting or pressure devices).

Emulsion flocculants must be fed following proper makeup procedures. Suitable inversion systems
should be utilized to allow for adequate inversion and feeding control. The quality of water used to
invert the polymer is important. Avoid using plant recycle water or other water sources high in
suspended solids, mineral salts and iron, and with a pH either below 6.5 or above 7.8.A dilution aging
tank is highly recommended,with a minimum of 30 minutes aging in order to gain full product activity.
Inverting the emulsion flocculant below a concentration of 0.2%, or above a concentration of 0.5%, is
not recommended. A positive displacement pump is recommended for feeding the inverted material to
the treatment system.
In some cases, continuous dilution of pre-inverted flocculant will enhance activity and generate more
cost-effective results. Improved performance using dilution water is site specific. To determine if post-
dilution is advantageous,feed inverted product through a standard mixing tee to an active dilution
water line. The water temperature should be close to ambient and low on suspended solids, mineral
salts and iron.
In most cases, inverted flocculant should be fed on the discharge side of the feed pump. There may be
isolated cases where the additional mixing rendered by distributing the polymer on the suction side of
the pump will yield better program results.

Keep containers closed and protect from frost and moisture. Low temperatures should be avoided
since viscosity increases and pumping problems can occur. When frozen, warm the product slowly to
ambient temperature and agitate with a low(<200) RPM mixer. After warming up to 8-10°C and re-
homogenization by gentle agitation for about 2 hrs, the product can be re-used without loss in
efficiency. Nevertheless freezing should be avoided.
When the product has been exposed to heat, the product should be gently agitated while its
temperature is allowed to lower to room temperature.After the product is back to room temperature,
about 2 hrs of gentle agitation should be sufficient to make the product ready for use. While product
performance should not be affected if the product freezes or warms up, some loss in physical stability
should be expected. If the product is to be stored for longer than two weeks, i.e., bulk tank storage,
periodic agitation of the product will help keep the product fully homogenized and ensure consistent
performance. Refer to the Material Safety Data Sheet (MSDS), SECTION 7,for the most current data.

Division of Water Resources -Wastewater Complex Permitting Section
Attn: Ms. Julie Grzyb

Raleigh, North Carolina 27699-1617
Subject: NPDES Stormwater Permit Minor Revision
Allen Steam Station Permit No. NCS000546
Gaston County
Dear Ms. Grzyb:
Duke Energy respectfully requests the inclusion of previously permitted stormwater outfall
SW015 to the Allen Steam Station industrial stormwater permit NCS000546. The following
narrative provides a timeline of SW015 and a justification for this request.
• On August 31, 2016, an update to the NPDES wastewater permit application was
submitted requesting that NC DEQ Division of Water Resources include the historically
permitted stormwater outfall SW015 and associated drainage area in the NC0004979
wastewater permit. This was requested because, at the time, this flow contained both
industrial stormwater and potentially, a wastewater contribution from ash basin seepage,
if any.
• In a July 2016 letter, Duke Energy requested the removal of SW015 from the Allen
industrial stormwater permit for future inclusion in the wastewater permit. NC DEMLR
approved this request on September 9, 2016.
• Subsequently, the contributing ash basin seepage flow to the SW015 drainage was
reconfigured to more permanently collect, pump, and return flow to the ash basin. The
potential ash basin seepage flow is not included in NPDES wastewater permit
NC0004979 and is currently being returned to the ash basin through a collection and
pumping system
• NPDES Wastewater Permit No. NC0004979 was received July 13, 2018 without the
inclusion of SW015.
• Stormwater outfall SW015 is a 36-inch reinforced concrete pipe (RCP) which discharges
to the Catawba River (Lake Wylie) and drains an approximately 163.6-acre area. The
drainage area runoff is from a large soil borrow area, as well as two ash structural fill
areas, and approximately one mile of gravel and dirt road. The coordinates of SW015
are 35° 10' 52" N by 81° 00' 21"W. The Active Ash Basin Emergency Spillway, WW007,
drains to the SW015 RCP, as demonstrated in the attached drainage area map.

Page 2
Due to the reconfiguration of the contributing wastewater source and the unaltered state of the
original SW015 drainage area, Duke Energy requests to reestablish the previously permitted
outfall SW015 in the subject permit. Copies of the illustration of the new configuration and a
drainage area map is included as attachments with this submittal.
If you have any questions, please contact Ms. Elizabeth Glenn [phone].
I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility of fines and imprisonment for knowing violations.

Subject: Allen Steam Station
NPDES Permit #:NC0004979

Dear Mr. Tuvia:
Duke Energy submits this written notification and status update of the Flue Gas Desulfurization
area Stormwater Basin (hereinafter"Stormwater Basin") overtopping that occurred at Allen
Steam Station on September 16, 2018 during tropical storm Florence, and as verbally reported
to the Agency on September 17, 2018.
Overtopping of the Stormwater Basin occurred during intense rainfall from tropical storm
Florence. Due to the intensity of rainfall, the two stormwater basin pumps could not displace
stormwater as quickly as in-flow arrived. Subsequently, stormwater from the event exited the
basin and crossed a vegetated swale to an inlet surrounded by silt fencing and rock checks.
The inlet discharges to a vegetated landing, surrounded by an earthen berm, rip-rapped slope,
silt-fencing, and multiple rock checks. Due to the precipitation intensity and saturated
landscape, an accurate volume of the stormwater exceeding the basin rim cannot be
determined. The overflow occurred for approximately 2 hours.
Station personnel and environmental staff surveyed the areas, post storm event. Included in this
survey was a review of the nearest perennial stream that empties into the plants cooling water
discharge canal and is approximately 70 yards from the rock checks. No indication of
environmental impacts from the overtopping were observed.
Station personnel conducted testing of the Stormwater basin pumps and performed a visual
survey of inlet structures for damage or blockage. While it is believed this was an anomalous
event caused by a short duration intense rainfall associated with the tropical system, a
stormwater drainage assessment is being re-validated to assure current site construction
activities have not modified expected inflows beyond the design capacity of the Stormwater
Basin.
If you have any questions, please contact Ms. Elizabeth Glenn [phone] or
[e-mail].
I certify, under penalty of law, that this document and all attachments were prepared under my direction
or supervision in accordance with a system designed to assure that qualified personnel properly gather
and evaluate the information submitted. Based on my inquiry of the person or persons who manage the
system, or those persons directly responsible for gathering the information, the information submitted is,
to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are

significant penalties for submitting false information, including the possibility of fines and imprisonment for

1.The facility has no source of standby power. MOORESVILLE REGIONAL OFFICE
Presently we have a contract with the City of Kings Mountain to process our wastewater in the event
of an extended outage at our plant. We also have 2 waste hauling companies that can haul our waste to
Kings Mountain in the event of an extended outage.
We are awaiting results from a study being conducted by the NC School of Government under a grant
we received for a regionalization/merger study with the City of Kings Mountain.
We also have a contact with W.K.Dickson for engineering services to eliminate our WWTP and tie into
Kings Mountain Sewer System. The engineering is substantially completed, and we are awaiting results
of the study being conducted by the NC School of Government before applying for a loan/grant to begin
the construction phase of eliminating our plant and contracting with the City of Kings Mountain to
process our wastewater.
Our present plans are to continue to operate as described above until we eliminate our WWTP and
connect to the City of Kings Mountain. This is because it would be extremely expensive to install backup
generators at the existing plant,which will be eliminated as soon as study is completed and construction
can be completed. The new system includes backup generators at all lift stations.
2.The facility had no safe way to collect grab samples from the effluent pipe.
We have started installing a set of steps to provide access to effluent discharge. This will include a
small platform,steps,handrails and toe boards. Work should be completed by 23 March 2018.
3.The effluent sampler lacks proper heating and insulation to maintain temperature above 0 degrees
in the sampler and to prevent tubing from freezing.
We have installed a heater in the cabinet and are in the process of insulating the tubing. Work should
be completed by 31 January 2018.
4.The skimmer needs to be fixed in the clarifier.Floating sludge was evident.
We are in the process of obtaining contractor to pull and repair skimmer.Work should be completed
by 30 March 2018.
5.The bar screen needs to be either fixed or replaced. Parts of the bar screen are missing allowing
debris to bypass the bar screen.
Bar screen will be pulled and repaired/replaced where bar is loose at one end. Whatever method is
used,the integrity of the bar screen will be insured before replacing. This should be completed by 23
March 2018.

6.The flow meter does not chart the flow.
The flow meter which was recently repaired and calibrated at a cost of$ 1,365.96 provides a printout
of(1)24 hour total flow(2)average gpm(3)min and max gpm with time of day.
This meter is not designed for charting. If a Chart is required,it will require replacing flowmeter. Our
intent was to continue use of present meter which furnishes required information in digital form until
the WWTP is eliminated as explained in item#1. Please advise.
7. The facility Chain of Custody forms fail to indicate the start and finish time and the date of the
composite sampler.
Our testing facility(Water Tech Labs)are aware of this deficiency. Until they modify their process we
are entering the start and finish times with date.

Dear Mr. Stowe:
Division of Water Quality (Division) personnel have discovered an error in Condition A (7) of the
subject permit issued on January 18, 2011. Regarding COD sampling, the permit incorrectly
specifies this as carbonaceous oxygen demand. This should be chemical oxygen demand.
Attached is a corrected page, which you should place in your permit file. All other terms and
conditions of this permit remain unchanged.
It is our understanding that you have been monitoring the correct parameter, chemical oxygen
demand. Therefore, you have not been deficient in monitoring, despite this error. If you have
questions, please contact Gil Vinzani at [[e-mail]] or at [phone].

'PART C-If you are a primary industry and this outfafl 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 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.

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 where 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 '/2 pump operation.
The 1 '/2 pumps operation adds an economical range or flexibility when units are
on partial load and when intake water temperatures are minimal.

5 83,000 126,000
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. (See section 2.2.6.4.) 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.
Use of the supplemental pumping system that was approved for operation from
July through September 2008 is proposed on an as-needed basis between July
and September of each year. During operation of the supplemental pumping
system, calculation of Allen Steam Station's CCW discharge temperature for
Outfall 001 will be modified to include the temperature of the supplemental

NPDES Permit No.NC0004979
Page 4 of 26
cooling water pumping system based on the system flow and Allen Steam
Station's CCW intake temperatures, as was done in 2008. The supplemental
pumping system will enable Allen Steam Station to extend power production in
compliance with current thermal limits that assure protection of the aquatic
community and downstream users.
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 are therefore flushed back with no harmful environmental
consequences.
2.2 Duffel! 002 - Ash Basin
2.2.1 Boiler Cleaning
All five boilers at Plant Allen are chemically cleaned with the next cleaning as
needed. The volume of the boilers determines the quantity of chemicals required
for a cleaning. Boilers #1 and #2 each have a waterside volume of 26,700
gallons. The volume of boilers #3, #4, and #5 is 40,100 gallons each. The
volume of dilute waste chemical discharged from unit#1 or#2 during a cleaning
is 294,000 gallons. The volume of diluted waste chemicals drained from #3, #4
and #5 totals 450,000 gallons each. These wastes are drained through
temporary piping to the permanent ash removal lines, which flow to the ash
basin. Immediately prior to the beginning of a boiler chemical cleaning
procedure, additional stop logs are added to the ash basin discharge structure.
This action assures longer retention time of the chemical wastes for proper
treatment through dilution, neutralization, precipitation, and ion-exchange as
documented in the Ash Basin Equivalency Demonstration (October 1976).

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 5 of 26
A list of the chemicals and amounts required to clean the boilers at Plant Allen
follows:
CLEANING CHEMICALS AMOUNT USED PER UNIT
Boiler#1 and #2 Boiler#3, #4 & #5
Sodium bromate 550 lbs 550 lbs
Ammonium carbonate 1000 lbs 1000 lbs
Ammonium hydroxide* 850 gal 950 gal
Hydrochloric acid* 3700 gal 5500 gal
Thiourea* 1680 lbs 2010 lbs
Citric acid 300 lbs 400 lbs
Sodium Sulfite 100 lbs 100 lbs
Ammonium bifluoride 1100 lbs 1700 lbs
Detergent (Triton—X) 20 gal 20 gal
Antifoam agent 10 gal 10 gal
During a chemical metals cleaning these chemicals are present in amounts
greater than the reportable quantity as identified under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA). If a spill
of any these chemicals were to occur, in most cases, it would be routed to the
ash basin for treatment.
Alternately, the boiler may be cleaned using ethylenediaminetetraacetic acid
(EDTA). If EDTA is 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.
2.2.2 Stormwater run-off
Storm water run-off enters the ash basin from the 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. A more
detailed description of the sump systems and stormwater run-off is included in
section 3.0.
2.2.3 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 150 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.
2.2.4 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

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 6 of 26
landfill. Wet sluicing is still utilized during times of start up and dry system upset.
Bottom ash sluicing to the basin requires approximately 6.0.
Plant Allen presently has additional air pollution control systems installed on
three units. Use of these systems entails the use of low concentrations of
ammonia and sulfur compounds. These systems aid in the collection of the ash
in the electrostatic precipitators.
2.2.5 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, but may need to be drained
occasionally. All such water would enter the floor drains and then be discharged
to the ash basin.
2.2.6 Miscellaneous Waste Streams
2.2.6.1 Turbine Non-destructive Testing
Approximately once per year, one turbine is tested for cracks in the
generator shaft using an ultrasonic nondestructive test. During the
process a maximum of 400 gallons of demineralized water mixed with 4
gallons of corrosion inhibitor is used and discharged to the ash basin.
2.2.6.2 Heat Exchanger Cleaning
From time to time, 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.
2.2.6.3 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 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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 7 of 26
2.2.6.4 Condenser Leakage Testing:
Fluorescing Dye Method - Approximately 1 lb. 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.
2.2.6.5 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 (See Section 3.4 for a more detailed
description of FGD stormwater sump)
2.2.6.5 Landfill Leachate collection discharge:
Industrial Solid Waste landfill (Permit No. 36-12) 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 will be pumped to ash basin.
2.2.7 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.
2.2.8 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. (See Section 3.4 for a more detail
description of rainfall run-off entering the yard drain sump.) Below is a description of
waste streams going to the yard drain sump:
2.2.8.1 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

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 8 of 26
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.
2.2.8.2 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.
2.2.8.3 Limestone Unloading/Storage Area Sump
Limestone sump collects stormwater from limestone unloading and
storage area and routes to YD sump via PH sump dischage line. (See
Section 3.4 for a more detail description of limestone sump)
2.2.9 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 machine 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 is 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.
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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 9 of 26
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.
2.2.10 Preheater Washes
Preheaters are backwashed with raw water approximately 2 times per year 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.
2.2.11 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.

2.2.12 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 flushed to the
powerhouse sump, which is then flushed to the yard drain sump. This sump also
receives stormwater from various drains located on the north end of the
powerhouse. (See Section 3.4 for a more detail description of rainfall run-off
entering the powerhouse sump.)
2.2.13 Physical Chemical Treatment System
The purpose of this system is to provide a chemical injection system for treatment of
dissolved pollutants that would not settle out of the wastestream through purely
physical means. The system treats 4-6 MGD sluice water to reduce the Total
Suspended Solids (TSS) and selenium to below permit limits. The three primary
settling cells are used to settle the solids (one at a time, while the inactive cells are
being cleaned).
The treatment channel conveys settled sluice wastewater to the secondary settling
or flocculation cell. Approximately 25-50 gpm of the settled waste stream from the
treatment channel is pumped into the chemical treatment building. This wastewater
stream provides the opportunity to take samples before and after treatment and
serves as the chemical injection point. The chemicals that are presently utilized for
treatment in this system are: sulfuric acid, ferric sulfate, ferric chloride and sodium
hydroxide.
After chemical addition and mixing in the treatment channel, the treated waste
stream is discharged into a floc settling basin to allow sufficient settling time for any
precipitated compounds to settle prior to discharge. Overflow from the final settling
cell flows through a vegetated ash delta prior to discharge to the main pond.
2.2.14 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 30%. 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.

2.2.15 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 SO3. The SO3 slurry 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 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.
2.3 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 002B — 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 get to 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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 12 of 26
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— Equip. 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 new
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.
2.8 (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 in the vicinity of the floc settling basin (as noted in Section 2.2.13
above)
3.0 STORMWATER GENERAL INFORMATION
3.1 Site Description
Allen Steam Station property covers approximately 953 acres. The powerhouse,
the plant yard, the coal pile, the switchyards, and associated material and
equipment storage areas cover about 65 acres. These developed areas are
generally flat. There are approximately 5 miles of rail access and 1.67 miles of
paved roadways on-site. Coal and limestone is shipped to the site by rail lines.
There is a 64 acre retired ash basin currently being converted to a double lined
with leachate collection landfill for disposal of coal combustion byproducts . The
active ash basin has a surface area of about 176 acres, and it receives runoff
from another 112 acres.

Page 13 of 26
Based on information from the Soil Survey of Gaston County, North Carolina, the
original site soils at Allen Steam Station were from the Gaston series. These
soils are classified as sandy clay loam with red clay in the subsoils. In developed
areas, the soil profile has been altered by grading and filling. The site
topography is generally flat with rolling hills in outlying, undeveloped areas.
3.2 Storm Water Drainage System
In developed areas, runoff flows overland to ditches and catch basins, which are
connected to a buried network of corrugated metal pipes (CMP). Rainfall runoff
from the coal pile and coal handling areas and portions of the plant yard goes to
the yard sumps that discharge to the ash basin. Storm water runoff from other
areas of the site is discharged to the Catawba River and the South Fork River.
Rainfall runoff from the transformer yard area and the 115 KV switchyard is
routed through oil trap tanks prior to being discharged.

Industrial wastewater from unit five flows into the powerhouse yard sump.
Stormwater runoff from a portion of the powerhouse roof, the plant yard, the fuel
oil unloading area, and the bulk fuel oil tank area drains to the powerhouse yard
sump. The portion of the powerhouse roof that drains to the powerhouse sump
is about 2.2 acres. About 85 percent of this drainage basin is paved or roofed.
Overflow from the powerhouse yard sump would spill to the ground and then flow
overland and could eventually reach the Catawba River. Overflow from the
powerhouse yard sump is permitted as NPDES Outfall 2(b). Overflow from the
powerhouse yard sump is not a normal occurrence.
Significant Materials/ Controls
Oil: The fuel oil bulk storage tank is an aboveground, galvanized steel cylinder
surrounded by a concrete containment sufficient in height to contain a total spill
plus rainfall. The total tank capacity is 100,000 gallons. There is a catch basin
inside the berm. This outlet has a valve which is normally closed. The
stormwater is inspected for the presence of oil, and if it is clean, it can be drained
if there is significant standing water. In the fuel oil unloading area, fuel is
transferred from an 8,000 gallon tanker truck to the bulk storage tank via
pipelines. DOT unloading procedures are followed. The fuel oil unloading area
is paved and surrounded by a one foot concrete curb and ramps to contain any
spills. There is a small sump to drain rainfall; the sump has a valve which is
normally closed. Spill clean-up supplies are located nearby. Piping from the
unloading area to the bulk fuel oil tank is aboveground or enclosed in a concrete
trench. The 48 transformers for the Units 1-5 precipitators contain a total of
7,560 gallons of mineral oil. About 60% of the precipitator transformers are
located within this drainage area. The maximum oil content of any single

from some of the powerhouse sumps. Industrial wastewater includes effluent
from the turbine room sumps and boiler room sumps. Stormwater runoff from a
portion of the plant yard and parts of coal handling drains to the yard drainage
sump. The total roofed area in this basin is about 1.5 acres including the
warehouse roof, the maintenance garage roof, and a portion of the powerhouse
roof. About half of this drainage basin is paved or roofed. Approximately 1,300
feet of railroad tracks pass through this drainage area. Overflow from the yard
drainage sump would discharge to the coal yard sump. Overflow from the sump
is not a normal occurrence.
Significant Materials/ Controls (See description for powerhouse yard sump for
additional information)
Kerosene: There is a 200-gallon aboveground, carbon steel kerosene tank
above the ash sluice trench.
Oil: Used oil is stored in a 4,500 gallon steel tank. The tank is surrounded by a
steel containment dike about five feet tall, and the piping is surrounded by a 6-
inch concrete curb. Rainfall that accumulates inside the dike can be drained by
opening a valve that drains to the ash trench which leads to the yard drainage
sump. When the used oil tank is full, the product is removed from site by tanker
truck. Small quantities of used oil are initially poured into 55-gallons drums. The
drums are stored in the used oil staging area under cover, adjacent to the
warehouse, for temporary storage. When the drums are full, they are emptied
into the used oil tank. Empty oil drums are stored outside, adjacent to the boat
shed. Approximately 250 gallons of oil are stored inside the maintenance garage
where floor drains flow to the yard drainage sump. The 48 transformers for the
Units 1-5 precipitators contain a total of 7,560 gallons of mineral oil. About 40%
of the precipitator transformers are located within this drainage area. The
maximum oil content of any single component is 205 gallons. Two transformers
associated with the wastewater and coal yard sumps each contain 270 gallons of
mineral oil. Fuel oil dispensers for the locomotives and bulldozers are located
adjacent to the maintenance garage.
Wastewater: Plant wastewater from equipment discharges, floor drains, sumps,
etc. is routed to the yard drainage sump. This wastewater may include oil,
chemical, and hazardous waste spills.
Coal: Coal dust is present along the railroad tracks and coal handling areas.
Ash: Ash pipelines run through this drainage area.
Chemicals: There is a 5,000 gallon tank of sulfuric acid located adjacent to the
warehouse. The tank is surrounded by a concrete dike with an outlet to the ash
line trench which leads to the yard drainage sump. Drums of various chemicals
are stored inside a covered, locked shed adjacent to the warehouse.
Hazardous Waste / Satellite Accumulation Areas: There is a satellite
accumulation area for waste paint, chemicals, solvents, cleaners, etc. adjacent to

the paint warehouse. Hazardous wastes are stored in a covered area adjacent
to the maintenance garage.
Laydown Area: There is a large laydown area adjacent to the warehouse. The
area is paved and fenced. Spare equipment and parts are stored in the laydown
area.
Coal Yard Sump Drainage Area
Location: East of the coal pile
Drainage Area: 24.1 acres
Area Description
The coal yard sump receives stormwater runoff from the coal pile and from parts
of coal handling area. Less than one percent of this drainage basin is paved or
roofed. Approximately 800 feet of railroad tracks pass through this drainage
area. Overflow from the coal yard sump would be conveyed to the Catawba
River. Overflow from the coal yard sump is permitted as NPDES Outfall 002a.
Overflow from the sump is not a normal occurrence.
Significant Materials/ Controls
Oil: Two transformers associated with the wastewater and coal yard sumps
each contain 270 gallons of mineral oil. A fuel oil dispenser for the bulldozers is
located in the northwest corner of the smaller coal pile.
Coal: Runoff from the coal pile and some coal handling areas is routed to the
coal yard sump.
Wastewater: Effluent from the septic system goes to coal yard sump.
CCP Landfill Sump Drainage Area
Location: South of the coal pile
Drainage Area: 64.0 acres
Area Description
The coal combustion products (CCP) landfill is double lined with a leak detection
system and leachate collection system. The contact water from the leachate
collection system will be pumped from the CCP landfill into the ash basin. There
is a 30 foot dike around the landfill. A stormwater drainage trench runs along the
south side of the landfill currently and is part of outfall 15. In the future, there will
be drainage ditches east and west of the landfill that will collect stormwater runoff
and pipe it to the ash basin.

3.5 Similarity of Storm Water Outfalls at Allen Steam Station
Monitoring all of the storm water outfalls at Allen Steam Station should not be
necessary since many of the outfalls convey storm water from areas of
substantially identical activities and materials. Storm water outfalls 8 and 15 are
representative for the entire site.
4.0 Hazardous and Toxic Substances
4.1 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 2c-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 very 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 its toxicity limits, since their
concentrations are extremely low.
4.2 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 being provided in order to qualify for the spill reportability exemption
provided under 40 CFR 117 and the Comprehensive Environmental Response
Compensation and Liability Act (CERCLA). These values below represent the
maximum quantities on-site that could be released at one time and sent to the

5.0 Allen Steam Station 316 Determination
5.1 Allen Steam Station 316(a) determination
Duke Energy's 316(a) demonstration (March 1976) concluded that the "heated
discharge from Plant Allen is such that the protection and propagation of a
balanced indigenous aquatic community in and on Lake Wylie is assured."
Duke's operation experience during the past five years under the thermal
limitations imposed in NPDES Permit No. NC0004979 substantiates the above
conclusion and further supports Duke's belief that the operating characteristics of
the station have a minimal effect of the aquatic environment of Lake Wylie.
Surveys of the aquatic community in Lake Wylie demonstrate that a Balanced
Indigenous Population exists in Lake Wylie. Accordingly, Duke requests a
316(a) variance and further requests that the thermal limitations imposed in the
permit be continued.
5.2 Allen Steam Station 316(b) Determination
In conjunction with the rulemaking process for the new Phase II 316(b) rule
pertaining to fish impingement and entrainment, historical data and permitting
records were reviewed. Initial 316(a) and 316(b) studies associated with
enactment of the Clean Water Act concluded that the location, construction
capacity, and design of the cooling water intake of Allen and other Duke Power
steam stations were not detrimental to the aquatic ecosystem and minimize
adverse environmental impacts. Both North Carolina and EPA regulators
concurred in 1976 that 316(b) fish impingement and entrainment studies were no
longer needed at that time. Although the new Phase II 316(b) rule for existing
facilities is currently being litigated, plans for information collection (PICs) are
being developed to conduct a Comprehensive Demonstration Study (CDS) to
determine required measures to be implemented per approval of NCDENR

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

NPDES Permit No. NC0004987
Page 4 of 30
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 4-.-3 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 turn 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 clarifier utilizes typical water treatment chemicals such as, aluminum sulfate
(alum), 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 aluminum hydroxide precipitate
formed as a result of adding aluminum sulfate (alum) and sodium hydroxide. The
quantity of alum used per year is approximately 14,000 gallons. The total
amount of caustic is roughly one quarter 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 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 pyrite system.

Marshall Steam Station,Catawba County
NPDES Permit No.NC0004987
Page 6 of 30
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 aluminum sulfate, sodium
hydroxide, hydrazine, ammonium hydroxide.
1 To date small closed system cleanings (e.g. heat exchangers) have not used these chemicals, reserved for
future use.

NPDES Permit No. NC0004987
Page 7 of 30
2.2.3.4 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 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.

4th Step (Neutralization Solution)
Boiler#1 or#2 Boiler#3 or#4
Soda Ash 4400 lb NA
Trisodium Phosphate NA 3000 lb
Prior to a boiler cleaning the ash basin water level is lowered and additional stop
logs are added to the ash basin discharge structure. This process assures
longer retention time of the chemical wastes for proper treatment through
dilution, neutralization, precipitation, and ion-exchange as documented in the Ash
Basin Equivalency Demonstration (October 1976).
Alternately, the boiler may be cleaned using ethylenediaminetetraacetic acid
(EDTA). If EDTA is 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 basin, ash removal lines
and rainfall run-off from the basin watershed area. Details of storm water the runoff that
flows into the ash basin is described in section 4.3.
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°Ao 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.

Marshall Steam Station,Catawba County
NPDES Permit No. NC0004987
Page 9 of 30
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 new 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 present lift stations
serving the vendor facilities and Units 3 and 4 have been upgraded.
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 I Quantity I Location
2-Propanol 4 gal. Lab/Warehouse
Glycerin 4 gal. Lab/Warehouse
Indigo carmine 0.3 lb Lab
Dimethylaminobenzaldehyde 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 new 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

Marshall Steam Station,Catawba County
NPDES Permit No.NC0004987
Page 10 of 30
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 Recent 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 slurry of

Marshall Steam Station,Catawba County
NPDES Permit No. NC0004987
Page 11 of 30
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 slurry 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 Internal 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 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 Wastewater from Future Plant Additions
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.
2.3 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

Marshall Steam Station,Catawba County
NPDES Permit No.NC0004987
Page 12 of 30
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
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.

4.0 STORMWATER
4.1 Site Description
The site covers 2,043 acres. The station includes a plant yard of 28 acres, a six acre switching
station, and a coal storage yard of 36 acres. A 450-acre portion of the headwaters of
Holdsclaw Creek serves as an ash-settling basin with regulated outflow to Lake Norman.
Marshall Steam Station has recently undergone a large amount of construction. The site has
added a Flue Gas Desulfurization (FGD) system, a Selective Catalytic Reduction (SCR)
system, a wetlands wastewater treatment plant, a limestone unloading/stacker system, a
gypsum stacker, a FGD landfill and various storage and maintenance buildings.
Approximately 80 acres northeast of the FGD landfill are being used to place flyash in a
structural fill. A 58 acre retired ash landfill is located east of the ash basin. A new ash landfill
is currently under construction. The site has a sanitary wastewater treatment lagoon and
several construction spoil areas. There are approximately six miles of rail access and three
miles of paved roadways on-site.
Soils at Marshall Steam Station are typical of the region and are predominantly micaceous
sandy silts and silty sands with some clayey sands in flatter areas. The topography is
generally flat with rolling hills in outlying, undeveloped areas.
In developed areas, runoff is collected by catch basins and conveyed through a buried network
of corrugated metal pipes (CMP). The network was originally designed to route flow to several
primary trunk lines, which discharged directly to Lake Norman. In 1976 runoff from most areas
with significant materials and activities was routed through either the yard holding sumps or the
oil trap tank. Effluent from the yard holding sumps is pumped to the ash basin. Storm water
processed through the oil trap tank is discharged to Lake Norman.
Storm water runoff from the FGD area enters yard drains and is then routed via gravity flow
through subsurface piping to a storm water detention pond. This pond then discharges to the
station transfer sump and then to Yard Sump No. 2. Yard sump No. 2 eventually discharges
via the ash basin.
Runoff from the FGD Landfill, the Beneficial Structural Fill Area, the Closed Ash Landfill, the
Gypsum Stacker, the Limestone Stacker, the FGD Constructed Wetlands and the Bottom Ash
Operations all eventually drain into the ash basin.
Marshall Steam Station has 11 storm water discharges and six NPDES process water outfalls.
Four of the NPDES outfalls also contain storm water. The storm water discharges are
described in Section 4.3. The six NPDES discharges are described as follows:
• NPDES Outfall #001 — Once-Through Cooling Water
2 SPCC Plan required by 40 CFR 112.

Marshall Steam Station,Catawba County
NPDES Permit No. NC0004987
Page 14 of 30
This discharge contains non-contact cooling water from plant equipment.
• NPDES Outfall #002 - Ash Settlings Basin Discharge
This discharge is the outflow from the ash-settling basin. Plant wastewater including ash
sluicing, treated sewage, equipment discharge, and chemical waste goes to the ash
basin. Runoff from the coal pile, bottom ash operations, beneficial structural fill area and
the closed ash landfill is routed to the ash basin via surface ditches. Runoff from the plant
yard is routed to the ash basin via the yard sumps. Additionally, drainage from the newly
constructed areas of the site such as FGD storm water, FGD process water treated via
the constructed wetlands system, treated water from the WWTP, the FGD landfill and
drainage from the gypsum and limestone radial stackers go to the ash basin.
• NPDES Outfall 002A—Yard Sump #1 Overflows
If the yard sump were inundated during a large storm event or spill, or if the power failed,
the overflow would be conveyed to Lake Norman through Outfall SW007. Overflow from
the yard sump is not a normal occurrence.
• NPDES Outfall 002B —Yard Sump #2 Overflows
This outfall is the emergency overflow for yard sump #2.
• NPDES Outfall #003 — Non-contact Cooling Water from the Induced Draft Fan Control
House
This is air conditioning condensate from the heat exchanger for the Unit 4 ID Fans
electronics. This outfall also conveys yard drainage and is dually listed as Outfall SW009
in Section 2.2.

4.2 Facility Drainage and Inventory of Significant Materials and Controls
Based on pipe networks and site topography, the Marshall Steam Station site was divided into
individual drainage basins as shown on the attached site drawings. This section details eleven
storm water outfalls to Lake Norman. To provide a complete description of the storm water
drainage system, the yard sump system is also characterized. Additional outfalls have been
excluded because either they have been abandoned or because runoff is from a small area,
which does not contain significant materials.
A description of the drainage area, significant materials, and material control measures is
presented for each drainage basin. In addition to the significant materials particular to each
drainage basin, herbicides are applied to selected areas throughout Marshall Steam Station to
eliminate undesirable vegetation along railways, ash pipelines, and the perimeter fence.
Herbicides are also applied, as needed, in the gravel parking lots, switchyard, and laydown
areas. Herbicides are sprayed around the fuel oil bulk storage tanks, yard sumps, transformers,
trailers, and the intake structure. All herbicides used at Marshall Steam Station are approved by
the company and considered safe to the environment when used according to directions.
Records are retained at the site which document information such as: the areas treated, the
herbicide used and the amounts of herbicide used

Drainage area 2B includes the newly constructed FGD, the Wastewater Treatment Plant and
ancillary parking areas that serve these areas. Catch basins located along the additional 2000
ft2 of roadway and parking lots within these areas route storm water into a detention pond
located at the southeastern corner of the drainage area. Discharge from this pond is pumped
into the transfer sump (located in the adjacent Drainage Area 9). The storm water is then
pumped from the transfer sump into Yard Sump 2. Effluent from yard sumps is pumped to the
ash-settling basin.
Significant Materials/ Controls
Oil: Transformers located north of the switchgear building contain a total of 5,300-gallons of
oil. The maximum reservoir size in each of the four transformers is 1,325-gallons. A
containment pad is located at the base of these transformers.
An emergency quench pump fuel oil tank is located on the north end of the absorber
building. This tank has a capacity of 100 gallons. This AST is located within
containment. The fill station for this AST is located at the tank.

Wastewater:
Plant wastewater from equipment discharges, floor drains, sumps, etc. is routed to the
WWTP located within this drainage area. After treatment, this waste water is pumped via
underground piping to the constructed wetlands treatment system and is eventually
discharged via the ash basin. This wastewater may include process water from the FGD
as well as oils, chemicals, and hazardous material spills.
Gypsum and Limestone: Overhead conveyors which transport limestone and gypsum are
located within this drainage area. However, these conveyors are covered and should not
represent a significant threat to storm water. Additionally, areas where these conveyors
cross roads or ponds are completely encapsulated to further minimize the threat of a
release.
4.5 Other Drainage Areas
• "Drainage Area 13"- Gypsum Radial Stacker
Discharge Structure: Two 24" 4 CMP
Location: Detention Pond
Drainage Area: 6 acres
Area Description
This drainage area consists of sheet flow and piped runoff from the gypsum stacking area and
soil borrow area. Gypsum is a byproduct of the FGD area. It is transported by covered
conveyors from the FGD site to the gypsum stacker area, where it is stacked in a radial
fashion. The soil borrow area adjacent to the radial stacker also contributes to this drainage
area. The drainage from the soil borrow area consists of the portion closest to the road.
Drainage from these areas is engineered to flow into a storm water detention pond, which
discharges into a finger of the ash basin. Discharge from this finger eventually reaches the
ash basin.
Significant Materials/ Controls
Oil: A 500-gallon AST and a 5,000-gallon AST containing fuel oil are located within this
drainage area. These ASTs are situated within a plastic-lined containment basin with no drain.
These ASTs are owned and operated by Southeastern Fly Ash (SEFA).
Gypsum: Gypsum is stacked in the area until it is shipped off by trucks to the wallboard
facility. The gypsum piles are contained on three sides by a berm to prevent storm water
runoff to these areas. The north side of the area is open to convey the storm water through
roadside ditches into two pipes which drain into a detention pond.
• "Drainage Area 14"- Soil Borrow Area
Discharge Structure: 24" 4 CMP
Location: Detention Pond

• "Drainage Area 15"- FGD Landfill
Discharge Structure: 24" 4) CMP
Location: Finger of the Ash Basin
Drainage Area: 20 acres
Area Description
This drainage area is composed of the entire FGD landfill.
Significant Materials/ Controls
Gypsum: Gypsum is one of the significant materials associated with the drainage area.
Gypsum that cannot be sold and is not of quality is disposed of in this area. The surface
water flow from the landfill will typically collect at the lower end of the cell and discharge
into the storm water collection pond located at the southern end of the landfill. From the
storm water basin, the runoff is piped into a finger of the ash basin that eventually
discharges into the ash basin.
FGD Wastewater Treatment Sludge: The sludge scrapped from the bottom of the wastewater
treatment facility is brought to the gypsum landfill. This process is performed because the
wastewater sludge is mixed with the gypsum to form a more dense substance that will not
be carried by the wind.
Other Materials in Landfill Include: asbestos, flyash, bottom ash, construction and demolition
debris.
• "Drainage Area 16" — Coal Pile
Discharge Structure: Surface Ditches

5.0 Hazardous and Toxic Substances
5.1 Hazardous and Toxic Substances Table 2c-3
At MSS, 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 2c-3 that may be in the discharge are
as follows:
Marshall Steam Station Hazardous and Toxic Substances

5.2 40 CFR 117 and CERCLA Hazardous Substances
The table below identifies hazardous substances located on-site that may be released to the ash
basin during a spill. Substances listed are present in quantities equal to or greater than the
reportable quantity (RQ) levels as referenced in 40 CFR 117, 302 and 355. This list is being provided
in order to qualify for the spill reportability exemption provided in 40 CFR 117 and the Comprehensive
Environmental Response Compensation and Liability Act (CERCLA).

quantities discharged. Various amounts of these substances may go to the ash basin for treatment due to use in site
laboratories, small leaks, spills, or drainage from closed loop systems. Treatment of these substances and their by-
products is achieved by physical and biological activity in the ash basin.
*Listed in 40 CFR 302.4-Table 302.4 List of Hazardous Substances and Reportable Quantities.
6.0 Marshall Steam Station 316 Determination
6.1 316(a) Determination
Duke Energy's operating experience during the past five years under the thermal limitations
imposed in NPDES Permit No. NC0004987 substantiates EPA's 316(a) determination for
Marshall (May 1975) 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." This is supported
by the enclosed report entitled, "Assessment of Balanced and Indigenous Populations in Lake
Norman near Marshall Steam Station".
In Duke's judgment 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 Energy requests that the thermal
limitations in the present permit be continued.
6.2 Marshall Steam Station 316(b) Determination
In conjunction with the rulemaking process for the new Phase II 316(b) rule pertaining to fish
impingement and entrainment, historical data and permitting records were reviewed. Initial
316(a) and 316(b) studies associated with enactment of the Clean Water Act concluded that the
location, construction capacity, and design of the cooling water intake of Marshall and other Duke
1

NPDES Permit No. NC0004987
Page 28 of 30
Energy steam stations were not detrimental to the aquatic ecosystem and minimize adverse
environmental impacts. Both North Carolina and EPA regulators concurred in 1976 that 316(b)
fish impingement and entrainment studies were no longer needed at that time. When the new
Phase II 316(b) Rule (Rule) was issued, Duke Energy developed Proposals for Information
Collection (PICs) and initiated approved 316(b) field studies at its applicable steam stations for
the eventual development of Comprehension Demonstration Studies (CDSs) to be used to
determine Rule compliance. When the Rule was remanded back to EPA for revision, CDSs were
no longer applicable and state agencies were instructed to use Best Professional Judgment
(BPJ) in the interim to determine 316(b) impacts or the lack thereof. Currently, Duke Energy is
summarizing the results of the 316(b) study at Marshall Steam Station and will be submitting an
Impingement Characterization and Adverse Environmental Impact Report, BPJ Report, and 40
CFR §122.21(r)(2), (3), and (5) Source Waterbody Physical Data, Cooling Water Intake Structure
Data, and Cooling Water System Data. These reports should be ready for submittal to the
NCDENR in early 2010.
Ash Basin Capacity
Part I Section 15 of the existing NPDES permit for Marshall Steam Station 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.
Determination of Wet Weather Detention Volume: Wet Weather Detention Volume is the sum of
the runoff accumulated in the ash basin which results from a 10-yr 24-hr storm (assuming 100%
runoff) plus the maximum 24-hr dry weather waste stream which discharges to the Ash Basin (refer
to NPDES Permit NC0004961)

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"Xin
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 whit±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

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 where 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 '/2 pump operation.
The 1 '/2 pumps operation adds an economical range or flexibility when units are
on partial load and when intake water temperatures are minimal.
Condenser Coolin• Water Pum• Ca*acities

4 83,000 111,200 126,000
5 83,000 126,000
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. (See section 2.2.6.4.) 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.
Use of the supplemental pumping system that was approved for operation from
July through September 2008 is proposed on an as-needed basis between July
and September of each year. During operation of the supplemental pumping
system, calculation of Allen Steam Station's CCW discharge temperature for
Outfall 001 will be modified to include the temperature of the supplemental

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 4 of 26
cooling water pumping system based on the system flow and Allen Steam
Station's CCW intake temperatures, as was done in 2008. The supplemental
pumping system will enable Allen Steam Station to extend power production in
compliance with current thermal limits that assure protection of the aquatic
community and downstream users.
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 are therefore flushed back with no harmful environmental
consequences.
2.2 Outfall 002 - Ash Basin
2.2.1 Boiler Cleaning
All five boilers at Plant Allen are chemically cleaned with the next cleaning as
needed. The volume of the boilers determines the quantity of chemicals required
for a cleaning. Boilers#1 and #2 each have a waterside volume of 26,700
gallons. The volume of boilers #3, #4, and #5 is 40,100 gallons each. The
volume of dilute waste chemical discharged from unit#1 or#2 during a cleaning
is 294,000 gallons. The volume of diluted waste chemicals drained from #3, #4
and #5 totals 450,000 gallons each. These wastes are drained through
temporary piping to the permanent ash removal lines, which flow to the ash
basin. Immediately prior to the beginning of a boiler chemical cleaning
procedure, additional stop logs are added to the ash basin discharge structure.
This action assures longer retention time of the chemical wastes for proper
treatment through dilution, neutralization, precipitation, and ion-exchange as
documented in the Ash Basin Equivalency Demonstration (October 1976).

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 5 of 26
A list of the chemicals and amounts required to clean the boilers at Plant Allen
follows:
CLEANING CHEMICALS AMOUNT USED PER UNIT
Boiler#1 and #2 Boiler#3, #4 & #5
Sodium bromate 550 lbs 550 lbs
Ammonium carbonate 1000 lbs 1000 lbs
Ammonium hydroxide* 850 gal 950 gal
Hydrochloric acid* 3700 gal 5500 gal
Thiourea* 1680 lbs 2010 lbs
Citric acid 300 lbs 400 lbs
Sodium Sulfite 100 lbs 100 lbs
Ammonium bifluoride 1100 lbs 1700 lbs
Detergent (Triton —X) 20 gal 20 gal
Antifoam agent 10 gal 10 gal
During a chemical metals cleaning these chemicals are present in amounts
greater than the reportable quantity as identified under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA). If a spill
of any these chemicals were to occur, in most cases, it would be routed to the
ash basin for treatment.
Alternately, the boiler may be cleaned using ethylenediaminetetraacetic acid
(EDTA). If EDTA is 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.
2.2.2 Stormwater run-off
Storm water run-off enters the ash basin from the 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. A more
detailed description of the sump systems and stormwater run-off is included in
section 3.0.
2.2.3 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 150 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.
2.2.4 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

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 6 of 26
landfill. Wet sluicing is still utilized during times of start up and dry system upset.
Bottom ash sluicing to the basin requires approximately 6.0.
Plant Allen presently has additional air pollution control systems installed on
three units. Use of these systems entails the use of low concentrations of
ammonia and sulfur compounds. These systems aid in the collection of the ash
in the electrostatic precipitators.
2.2.5 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, but may need to be drained
occasionally. All such water would enter the floor drains and then be discharged
to the ash basin.
2.2.6 Miscellaneous Waste Streams
2.2.6.1 Turbine Non-destructive Testing
Approximately once per year, one turbine is tested for cracks in the
generator shaft using an ultrasonic nondestructive test. During the
process a maximum of 400 gallons of demineralized water mixed with 4
gallons of corrosion inhibitor is used and discharged to the ash basin.
2.2.6.2 Heat Exchanger Cleaning
From time to time, 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.
2.2.6.3 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 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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 7 of 26
2.2.6.4 Condenser Leakage Testing:
Fluorescing Dye Method -Approximately 1 lb. 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.
2.2.6.5 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 (See Section 3.4 for a more detailed
description of FGD stormwater sump)
2.2.6.5 Landfill Leachate collection discharge:
Industrial Solid Waste landfill (Permit No. 36-12) 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 will be pumped to ash basin.
2.2.7 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.
2.2.8 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. (See Section 3.4 for a more detail
description of rainfall run-off entering the yard drain sump.) Below is a description of
waste streams going to the yard drain sump:
2.2.8.1 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

Men Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 8 of 26
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.
2.2.8.2 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.
2.2.8.3 Limestone Unloading/Storage Area Sump
Limestone sump collects stormwater from limestone unloading and
storage area and routes to YD sump via PH sump dischage line. (See
Section 3.4 for a more detail description of limestone sump)
2.2.9 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 machine 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 is 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.
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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 9 of 26
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.
2.2.10 Preheater Washes
Preheaters are backwashed with raw water approximately 2 times per year 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.
2.2.11 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.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 10 of 26
2.2.12 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 flushed to the
powerhouse sump, which is then flushed to the yard drain sump. This sump also
receives stormwater from various drains located on the north end of the
powerhouse. (See Section 3.4 for a more detail description of rainfall run-off
entering the powerhouse sump.)
2.2.13 Physical Chemical Treatment System
The purpose of this system is to provide a chemical injection system for treatment of
dissolved pollutants that would not settle out of the wastestream through purely
physical means. The system treats 4-6 MGD sluice water to reduce the Total
Suspended Solids (TSS) and selenium to below permit limits. The three primary
settling cells are used to settle the solids (one at a time, while the inactive cells are
being cleaned).
The treatment channel conveys settled sluice wastewater to the secondary settling
or flocculation cell. Approximately 25-50 gpm of the settled waste stream from the
treatment channel is pumped into the chemical treatment building. This wastewater
stream provides the opportunity to take samples before and after treatment and
serves as the chemical injection point. The chemicals that are presently utilized for
treatment in this system are: sulfuric acid, ferric sulfate, ferric chloride and sodium
hydroxide.
After chemical addition and mixing in the treatment channel, the treated waste
stream is discharged into a floc settling basin to allow sufficient settling time for any
precipitated compounds to settle prior to discharge. Overflow from the final settling
cell flows through a vegetated ash delta prior to discharge to the main pond.
2.2.14 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 30%. 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.

NPDES Permit No.NC0004979
Page 11 of 26
2.2.15 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 SO3. The SO3 slurry 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 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.
2.3 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 002B — 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 get to 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— Equip. 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 new
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.
2.8 (Internal) Outfall 005 —VWNTS 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 in the vicinity of the floc settling basin (as noted in Section 2.2.13
above)
3.0 STORMWATER GENERAL INFORMATION
3.1 Site Description
Allen Steam Station property covers approximately 953 acres. The powerhouse,
the plant yard, the coal pile, the switchyards, and associated material and
equipment storage areas cover about 65 acres. These developed areas are
generally flat. There are approximately 5 miles of rail access and 1.67 miles of
paved roadways on-site. Coal and limestone is shipped to the site by rail lines.
There is a 64 acre retired ash basin currently being converted to a double lined
with leachate collection landfill for disposal of coal combustion byproducts . The
active ash basin has a surface area of about 176 acres, and it receives runoff
from another 112 acres.

Allen Steam Station,Gaston County
NPDES Permit No.NC0004979
Page 13 of 26
Based on information from the Soil Survey of Gaston County, North Carolina, the
original site soils at Allen Steam Station were from the Gaston series. These
soils are classified as sandy clay loam with red clay in the subsoils. In developed
areas, the soil profile has been altered by grading and filling. The site
topography is generally flat with rolling hills in outlying, undeveloped areas.
3.2 Storm Water Drainage System
In developed areas, runoff flows overland to ditches and catch basins, which are
connected to a buried network of corrugated metal pipes (CMP). Rainfall runoff
from the coal pile and coal handling areas and portions of the plant yard goes to
the yard sumps that discharge to the ash basin. Storm water runoff from other
areas of the site is discharged to the Catawba River and the South Fork River.
Rainfall runoff from the transformer yard area and the 115 KV switchyard is
routed through oil trap tanks prior to being discharged.
3.3 Characterization of Drainage Basins

3.5 Similarity of Storm Water Outfalls at Allen Steam Station
Monitoring all of the storm water outfalls at Allen Steam Station should not be
necessary since many of the outfalls convey storm water from areas of
substantially identical activities and materials. Storm water outfalls 8 and 15 are
representative for the entire site.
4.0 Hazardous and Toxic Substances
4.1 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 2c-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 very 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 its toxicity limits, since their
concentrations are extremely low.
4.2 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 being provided in order to qualify for the spill reportability exemption
provided under 40 CFR 117 and the Comprehensive Environmental Response
Compensation and Liability Act (CERCLA). These values below represent the
maximum quantities on-site that could be released at one time and sent to the
ash basin. They do not reflect quantities that are discharged through typical use.

5.0 Allen Steam Station 316 Determination
5.1 Allen Steam Station 316(a) determination
Duke Energy's 316(a) demonstration (March 1976) concluded that the "heated
discharge from Plant Allen is such that the protection and propagation of a
balanced indigenous aquatic community in and on Lake Wylie is assured."
Duke's operation experience during the past five years under the thermal
limitations imposed in NPDES Permit No. NC0004979 substantiates the above
conclusion and further supports Duke's belief that the operating characteristics of
the station have a minimal effect of the aquatic environment of Lake Wylie.
Surveys of the aquatic community in Lake Wylie demonstrate that a Balanced
Indigenous Population exists in Lake Wylie. Accordingly, Duke requests a
316(a) variance and further requests that the thermal limitations imposed in the
permit be continued.
5.2 Allen Steam Station 316(b) Determination
In conjunction with the rulemaking process for the new Phase II 316(b) rule
pertaining to fish impingement and entrainment, historical data and permitting
records were reviewed. Initial 316(a) and 316(b) studies associated with
enactment of the Clean Water Act concluded that the location, construction
capacity, and design of the cooling water intake of Allen and other Duke Power
steam stations were not detrimental to the aquatic ecosystem and minimize
adverse environmental impacts. Both North Carolina and EPA regulators
concurred in 1976 that 316(b) fish impingement and entrainment studies were no
longer needed at that time. Although the new Phase II 316(b) rule for existing
facilities is currently being litigated, plans for information collection (PICs) are
being developed to conduct a Comprehensive Demonstration Study (CDS) to
determine required measures to be implemented per approval of NCDENR

Subject: NPDES Permit major modification
Permit No. NC0004979
Allen Steam Station
Gaston County
Dear Mr. Immel:
Division personnel have reviewed and approved your request for major modification.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is modified
pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 17, 2007 (or as subsequently amended.)
This permit modification addresses the request for a major modification regarding the
elimination of the selenium limit at Outfall 002.
The permit authorizes Duke Energy Carolinas, LLC to discharge treated industrial
wastewater from the Allen Steam Station Wastewater Treatment Plant to the Catawba River and
the South Fork Catawba River, class WS-IV and B waters in the Catawba River Basin. The final
permit includes discharge limitations/or monitoring for flow, oil and grease, total suspended
solids, arsenic, chloride, copper, iron, mercury, nickel, selenium, zinc, total nitrogen, total
phosphorus, pH, and chronic toxicity.
The following modifications included in the May 6thdraft permit remain in the final
permit:
• The weekly average effluent limit for selenium at Outfall 002 has been deleted. Data
analysis indicated that there was no reasonable potential for this parameter to exceed the
water quality standard in the receiving stream. There will be monthly monitoring of total
selenium at both Outfall 002 and internal outfall 005.

Letter to Mr. Immel
Page 2
• Due to the new wastestream from the Flue Gas Desulfurization WWTP that will be
discharged into the ash settling basin above Outfall 002, quarterly monitoring for the
following parameters will now be required at Outfall 002: total arsenic, total cadmium,
total chromium, chloride, total mercury, total nickel, total silver, total zinc, and total
beryllium. Quarterly monitoring for these parameters is the minimum requirement for a
major industrial discharger to North Carolina streams.

Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC 1251,et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June,July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system,or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. Use of this method requires prior approval by the Director. This method
may only be used in situations where effluent flow rates vary less than 15 percent. The following
restrictions also apply:
> Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
Version 10/10/2007

Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the "daily discharge"is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.2)
Daily Maximum
The highest "daily discharge" for conventional and other non-toxicant parameters. NOTE: Permittees may not
submit a "daily average" calculation [for determining compliance with permit limits] for toxicants. See the relevant
Federal effluent guideline[s] for the appropriate calculation interval.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s),that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or"the Division"
The Division of Water Quality,Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility,or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean,values of"0" (or"< [detection level]' shall be considered =1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Version 10/10/2007

In accordance with(4) above,influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the "daily discharge"is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or"the Division"
The Division of Water Quality,Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility,or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
eometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean,values of"0" (or"< [detection level]") shall be considered=1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Instantaneous flow measurement
A measure of flow taken at the time of sampling,when both the sample and flow will be representative of the total
discharge.

8. Topography(relationship to flood plain included): The site was graded considerably when
built,which removed existing contours. The steam plant is constructed above the high water
elevation of Lake Wylie(the receiving stream). The surrounding area has gently rolling
topography(slopes<10%).
9. Location of nearest dwelling: Approx. 1000+feet from the steam plant site.
10. Receiving stream or affected surface waters: Catawba River(Lake Wylie)-outfalls 002,
002A, 002B, 004&005. South Fork Catawba River(Lake Wylie)-outfalls 001 & 003.

b. River Basin and Subbasin No.: Catawba 030834
c. Describe receiving stream features and pertinent downstream uses: Outfalls 002,
002A, 002B, 004&005 enter the main segment of the Catawba River(Take Wylie),
which is used for primary and secondary recreation and as a receiving stream for point
source (NPDES) discharges both upstream and downstream of the steam plant. There
are no known municipal water intakes located above or below these outfalls. Outfalls
001 & 003 enter a manmade discharge canal located west of the steam plant. This
canal travels for a distance of 1.2 miles where it enters the South Fork Catawba
River(an arm of Lake Wylie). This area is also used for primary and secondary
recreation and there are no known water intakes from the point of discharge to the
mouth of the South Fork of the Catawba River.
PART IT-DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
Outfall
001 002 002A 002B 003 004 005
L a. Volume of wastewater(MGD): 626.3 20.7 N/A N/A 4.5 6.5 0.003
b. What is the current permitted capacity: No flow limit for any outfall in Permit.
c. Actual treatment capacity of current facility(current design capacity): N/A
d. Date(s)and construction activities allowed by previous ATCs issued in the previous
two years: An Authorization to Construct for the construction of a physical chemical
treatment system was issued on June 21, 2004 for the following:
1. Three primary settling cells
2. A Treatment channel
3. A Chemical injection system, and
4. A Final settling/flocculation cell
The purpose of this system is to provide chemical injection for treatment of
dissolved pollutants that will not settle out of the waste stream through purely

Page Three
Physical means. The system will treat 18-24 MGD sluice water to reduce the TSS
and Selenium to below permit limits. The three primary settling cells will be used to
settle the solids(only one operating at a time, while the inactive cells are being
cleaned).
e. Description of existing or substantially constructed WWT facilities:
Outfall 001-Waste stream consists of non-contact cooling water from a system that
removes heat from the condensers and other heat exchangers. Each of the 5 units at
Plant Allen has two condenser cooling pumps.
Outfall 002-Ash Basin. Waste stream consist of chemicals from boiler cleaning
procedure and sanitary waste from a septic tank(serving approximately 150
employee). pH adjustment(carbon dioxide, sulfuric acid, and sodium hydroxide) is
available at the effluent, if needed. Other sources for wastewater entering the ash
basin and discharging at outfall 002 include stormwater runoff from the coal pile area,
ash sluice recirculating water system,turbine non-destructive testing, heat exchanger
cleaning, condensate polishers, condensate leakage testing, yard drain sump, water
treatment system,preheater washes, laboratory wastes, the power house sump (unit
5), and physical chemical treatment system(see d above). Future sources include the
waste stream from a selective non-catalytic reduction system(to reduce NO emissions
by approximately 30%) and a flue gas desulfurization(FGD) system(for the
reduction of SO2 from the stack gas).
Outfall 002A-Coal yard sump overflow. An overflow pipe directs flow directly to
the Catawba River in the event that all pumps in the coal yard sump failed or
redundant power supply could not be activated in a timely manner
Outfall 002B -Power house sump overflow. An overflow pipe directs flow directly
to the Catawba River in the event that all pumps in the yard sump failed or redundant
power supply could not be activated in a timely manner.
Outfall 003 -Miscellaneous equipment cooling and seal water. Discharge is to the
CCW discharge canal.
Outfall 004 - Equipment cooling and intake screen backwash. e)f1 R A2,'t'f -
Outfall 005 -
f. Description of proposed WWT facilities: See part II, d above.
g. Possible toxic impacts to surface waters: This facility has consistently passed toxicity
tests required at outfall 002. Various chemicals are used during the cleaning and
maintenance of equipment (see list provided with the application package).

Page Four
h. Pretreatment Program(POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: Septage from the septic tank is removed as
needed by Stanley Septic Tank Services (permit# SDF-36-04). With the exception of fly ash,
no other residuals generation is expected. Duke Power Company has a non-discharge Permit
(WQ0003255) for the disposal of fly ash.
3. Treatment plant classification: Class I for outfall 002. Outfalls 001, 003 and 004 do not meet
the minimum criteria for a class I rating.
4. SIC Code(s): 4911 Wastewater Code(s): 68, 66 MTU Code(s): 50002
PART III-OTHER PERTINENT INFORMATION
1 Is this facility being constructed with Construction Grant Funds or are any public monies
involved(municipals only)? No
2. Special monitoring or limitations(including toxicity)requests:
a. Permittee has requested that monitoring be either eliminated or reduced for the
following parameters at outfall 002: Barium, BOD, Cadmium, Chromium, Copper,
Cyanide,Fecal Coliform,Naphthalene,Nickel, Phenol, Phosphorus, Sulfate and Zinc.
MRO staff can support a reduction in the monitoring frequency,however, eliminating
all monitoring may not be prudent. Defer to the NPDES Unit for review and
comment.
b. Permittee has requested continuation of the thermal limitations that are presently in
the NPDES permit. (An assessment report of balanced and indigenous populations in
Lake Wylie has been submitted by Duke Power with the permit renewal). According
to the submitted report, the results of data analyses for fish populations and
macroinvertebrates support continuation of the existing permitted thermal limits
c. Permittee requests that the current selenium limit be changed from a daily maximum
limit to a monthly average limit for the following reason: 40 CFR 131.36 list the
Criterion Maximum Cocentration(CMC) and the Criterion Continuous Concentration
(CCC) for selenium at 20 ug/1 and 5ug/l, respectively. Since the current selenium
limit of 31 ug/1 is based on the CCC value of 5 ug/1,the limit should be expressed as a
monthly average value. The Environmental Protection Agency's"Ambient Water
Quality Criteria for Selenium-198T'document page 34 and 40 CFR 131.36 also
supports this request. Defer to the NPDES Unit for review and comment.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4. Alternative Analysis Evaluation: There are no practicable alternatives for the elimination of
any of the existing waste streams.

Page Five
PART IV-EVALUATION AND RECOMMENDATIONS
The permittee is requesting renewal of the subject permit. Changes requested by Duke for
this renewal are discussed in Part III,No. 2 (a, b,c) above.
Review and approval of these monitoring changes will be necessary by the NPDES Unit.
According to Mr. Wylie, The construction of the physical chemical treatment system will be
completed by the end of February 2005.
Pending review and approval of the WLA and review and approval by P&E, it is
recommended that the Permit be renewed as requested.

Dear Mr. Goodrich,
The subject NPDES permit is scheduled to expire on May 31, 2005. As required by North
Carolina Administrative Code (15A NCAC 2H.0105(e)), this permit application for renewal is
being submitted at least 180 days prior to expiration of the current permit.
Please find enclosed in triplicate, the application for renewal, which includes the following
items:
• EPA Form 1
• EPA Form 2C
• EPA Form 2F
• Site maps
• Supplemental Information to the NPDES Application
• The Balanced Indigenous Population(BIP)Report
In review of historical monitoring data for outfall 002 many parameters have been continuously
measured at very low concentrations or below detection levels. It is therefore requested that
these parameters be either eliminated from monitoring requirements or reduced in monitoring
frequency. These parameters are as follows: Barium, BOD, Cadmium, Chromium, Copper,
Cyanide, Fecal Coliform, Naphthalene, Nickel, Phenol, Phosphorus, Sulfate and Zinc.
It is also requested that the current selenium limit is changed from a daily maximum limit to a
monthly average limit for the following reason:
40 CFR 131.36 list the Criterion Maximum Concentration (CMC) and the Criterion Continuous
Concentration (CCC) for selenium at 20 ug/1 and 5 ug/1, respectively. Since the current selenium

average value. The Environmental Protection Agency's"Ambient Water Quality Criteria for
Selenium— 1987" document.page 34 and 40 CFR 131.36 also supports this request.
The attached BIP report shows that the balanced indigenous aquatic community in Lake Wylie is
being maintained under the current limits. Accordingly, Duke Energy Corporation requests a
continuation of the thermal limitations that are presently in the NPDES permit.

CONTINUED FROM PAGE 3 OF FORM 2-C NC0004979 002
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 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

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. A schematic flow
diagram of water use, treatment, and discharges indicating typical (average) flow rates
for individual waste streams at Plant Allen is attached. All flows are based on historical
data where 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 '/2 pump operation.
The 1 %2 pumps operation adds an economical range or flexibility when units are
on partial load and when intake water temperatures are minimal.

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. (See section 2.2.6.4.) 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 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 other 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 are therefore flushed back with no harmful
environmental consequences.
2.2 Outfall 002 -Ash Basin
2.2.1 Boiler Cleaning
All five boilers at Plant Allen are chemically cleaned with the next cleaning as
needed. The volume of the boilers determines the quantity of chemicals
required for a cleaning. Boilers #1 and #2 each have a waterside volume of
26,700 gallons. The volume of boilers #3, #4, and #5 is 40,100 gallons each.
The volume of dilute waste chemical discharged from unit#1 or#2 during a
cleaning is 294,000 gallons. The volume of diluted waste chemicals drained
from #3, #4 and #5 totals 450,000 gallons each. These wastes are drained
through temporary piping to the permanent ash removal lines, which flow to the
ash basin. Immediately prior to the beginning of a boiler chemical cleaning
procedure, additional stop logs are added to the ash basin discharge structure.
This assures longer retention time of the chemical wastes for proper treatment
through dilution, neutralization, precipitation, and ion-exchange as documented
in the Ash Basin Equivalency Demonstration (October 1976).
A list of the chemicals and amounts required to clean the boilers at Plant Allen
follows:
CLEANING CHEMICALS AMOUNT USED PER UNIT
Boiler#1 and #2 Boiler#3, #4 & #5
Sodium bromate 550 lbs 550 lbs
Ammonium carbonate 1000 lbs 1000 lbs
Ammonium hydroxide* 850 gal 950 gal
Hydrochloric acid* 3700 gal 5500 gal
Thiourea* 1680 lbs 2010 lbs
Citric acid 300 lbs 400 lbs
Sodium Sulfite 100 lbs 100 lbs
Ammonium bifluoride 1100 lbs 1700 lbs
Detergent (Triton —X) 20 gal 20 gal
Antifoam agent 10 gal 10 gal
During a chemical metals cleaning these chemicals are present in amounts
greater than the reportable quantity as identified under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA). If a spill

of any these chemicals were to occur, in most cases, it would be routed to the
ash basin for treatment.
•
2.2.2 Stormwater run-off
Storm water run-off enters the ash basin from the from the ash basin's drainage area,
the yard drainage sump and the coal yard sump. The powerhouse sump discharges its
rainfall run-off into the yard drainage sump. A more detail description of the sump
systems and stormwater run-off is included in section 3.4.
2.2.3 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 150 people are responsible for the load on this system. An
average flow of 4850 GPD is treated by the system. The drinking water well
supplies the drinking water requirements of Plant Allen. Plant Allen is a non-
transient and non-community drinking water system. This drinking water system
is listed as ID # 01-36-704 in the NCDENR database.
2.2.4 Ash Sluice
Plant Allen utilizes electrostatic precipitators to remove fly ash from its stack
gases. These precipitators require approximately 10.0 MGD for fly ash sluicing
to the ash basin. Bottom ash sluicing to the basin requires approximately 6.0
MGD for a total average ash removal flow of 16.0 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
ammonia and sulfur compounds. These systems aid in the collection of the ash
in the electrostatic precipitators.
A Selective Non-Catalytic Reduction (SNCR) system has been installed on unit
1 to aid in the reduction of NOx emissions. 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. Additional SNCR systems are to be installed on the remaining 4
units at Allen over the next several years.
2.2.5 Recirculating Water System (RCW)
Plant Allen has 2 RCW systems: a chiller system and a pump cooling water
system. Both systems use the biocide H-550 or similar products. In addition, the
corrosion inhibitor CS or similar product is used. Generally, these systems are
closed loop, but may need to be drained occasionally. All such water would
enter the floor drains and then be discharged to the ash basin.

2.2.6 Miscellaneous Waste Streams
2.2.6.1 Turbine Non-destructive Testing
Approximately once per year, one turbine is tested for cracks in the
generator shaft using an ultrasonic nondestructive test. During the
process a maximum of 400 gal of demineralized water mixed with 4 gal of
corrosion inhibitor is used and discharged to the ash basin.
2.2.6.2 Heat Exchanger Cleaning
From time to time, it may be necessary to clean the small heat
exchangers with polyacrylamide, polyacrylate, sodium laurylsulfate and tri-
sodium phosphate. All wastes would be routed to the ash basin.
2.2.6.3 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 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.
2.2.6.4 Condenser Leakage Testing:
Fluorescing Dye Method - Approximately 1 lb. of a disodium fluorescing
dye added to 280,000 gals of demineralized water is used occasionally to
test the condensers for leakage. All wastes 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.

2.2.7 Ash Basin Treatment
CO2 Injection System - During warmer periods of the year, algae blooms occur in
the ash basin causing pH levels to rise. A CO2 system is utilized during these
events to maintain the pH level below 9.0 standard units.
Acid Injection System -An acid injection system utilizing 78-80 % sulfuric acid is
maintained as back-up to the CO2 system for pH adjustment
Sodium Hydroxide System -A sodium hydroxide injection system utilizing 25% or
50% sodium hydroxide is maintained for pH adjustment.
2.2.8 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. (See Section 3.4 for a more
detail description of rainfall run-off entering the yard drain sump.) Below is a
description of waste streams going to the yard drain sump:
2.2.8.1 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 'y
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.
2.2.8.2 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.
2.2.9 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 compromised of a clarifier, two pressure
filters, two activated carbon filters, two garnet filters, a reverse osmosis machine 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. Alum and 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

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 8 of 26
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 will backwash once per week. The contents of the
pressure filters will be changed out, as internal maintenance requires, and the
used filter medium will be disposed of in the ash basin.
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 is disposed of in the ash basin.
RO Prefilters:
There are 2 RO prefilter vessels containing garnet, which are used to filter
suspended solids. Both filters are backwashed once per week
with the backwashed material routed to the ash basin. Total waste for both
filters is 4500 gallons per week.
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 the
cleaner OSMO AD-20 (containing sulfamic acid) 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

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 9 of 26
once every 10 years with the spent resin going to the ash basin. Approximately
1 ml 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.
2.2.10 Preheater Washes
Preheaters are backwashed with raw water approximately 2 times per year 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.
2.2.11 Laboratory Wastes
The chemistry lab on site performs 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.
2.2.12 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 flushed to the
powerhouse sump, which is then flushed to the yard drain sump. This sump also
collects stormwater from various drains located on the north end of the powerhouse.
(See Section 3.4 for a more detail description of rainfall run-off entering the
powerhouse sump.)
2.2.13 Physical Chemical Treatment System
An Authorization to Construct permit number NC0004979A01 was issued to Allen
Steam Station on June 21, 2004 for a physical chemical treatment system that will
allow construction of:

Plant Men,Gaston County
NPDES Permit No.NC0004979
Page 10 of 26
• three primary settling cells,
• a treatment channel,
• a chemical injection system, and
• a final settling/focculation cell.
The purpose of this system is to provide a chemical injection system for treatment of
dissolved pollutants that will not settle out of the wastestream through purely
physical means. The system will treat 18-24 MGD sluice water to reduce the TSS
and selenium to below permit limits. The three primary settling cells will be used to
settle the solids (one at a time, while the inactive cells are being cleaned).
The treatment channel will convey settled sluice water to the secondary settling or
flocculation cell. Approximately 25-50 gpm of the settled waste stream from the
treatment channel will be pumped into the chemical treatment building. This
pumped stream will provide the opportunity to take samples before and after
treatment and serve as the waste stream's chemical injection point. The chemicals
that are presently permitted for treatment in this system are: sulfuric acid, ferric
sulfate and ferric chloride.
After chemical addition and mixing in the treatment channel, the treated waste
stream will be discharged into a floc setting basin to allow sufficient settling time for
any precipitated compounds to settle prior to discharge. Overflow from the final
settling cell will flow through a vegetated ash delta prior to discharge to the main
pond. There will be an alternative route to discharge from the vegitated ash delta
directly to the final discharge tower.
2.2.14 Wastewater from Future Plant Additions
2.2.14.1 Selective Non-Catalytic Reduction (SNCR)
As part of the compliance with the North Carolina Clean Air Initiative
(NCCAIR), Allen will install an urea based "trim" Selective Non-Catalytic
Reduction (SNCR) systems on all five units. The installation has been
completed for Unit 1. The trim SNCR systems are expected to reduce
NOx emissions by approximately 30%. 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.
Two pressure filters with polymer injection will be installed to provide
make up water to the SNCR system. Each pressure filter will be
backwashed once per week with a waste flow of 5000 gallons per

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 11 of 26
backwash. Each pressure filter will contain anthracite, quartz, garnet and
garnet/quartz support media.
2.2.14.2 Flue Gas Desulfurization (FGD)
The installation of a Wet Flue Gas Desulfurization (FGD) system is to be
installed at Allen in the future 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 to be used at Allen will collect the flue
gas after it passes through the electrostatic precipitator and route 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. An atomized 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 SO3. The SO3 slurry falls to the
bottom of the tank where a stream of air is injected to oxidize the slurry to
form gypsum (CaSO4•H2O). The gypsum slurry is drawn off the absorber
tank and subsequently 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 will be treated
in a wastewater treatment system that will discharge to the ash basin.
The FGD system will require a material handling system that will supply
limestone to the scrubber and a gypsum storage area for the gypsum
removed from the process. The limestone will come into the site by rail. 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 will carry it to a storage
pile. The runoff from this area is also routed to the ash basin.
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 was done 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. Overflow has
not occurred during the last permit cycle.
2.4 Outfall 002B — 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 was done 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

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 12 of 26
overflows, the waste water could potentially get to 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— Equip. 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 is also adding a new
chiller system for comfort cooling that will be a once through non contact cooling
water system and will discharge 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 with no harmful environmental
consequences.
3.0 STORMWATER GENERAL INFORMATION
3.1 Site Description
Allen Steam Station property covers approximately 953 acres. The powerhouse,
the plant yard, the coal pile, the switchyards, and associated material and
equipment storage areas cover about 65 acres. These developed areas are
generally flat. There are approximately 5 miles of rail access and 1 2/3 miles of
paved roadways on-site. Coal is shipped to.the site by rail lines. There is a 64
acre retired ash basin. The active ash basin has a surface area of about 176
acres, and it receives runoff from another 112 acres.

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 13 of 26
Based on information from the Soil Survey of Gaston County, North Carolina, the
original site soils at Allen Steam Station were from the Gaston series. These
soils are classified as sandy clay loam with red clay in the subsoils. In developed
areas, the soil profile has been altered by grading and filling. The site
topography is generally flat with rolling hills in outlying, undeveloped areas.
3.2 Storm Water Drainage System
In developed areas, runoff flows overland to ditches and catch basins, which are
connected to a buried network of corrugated metal pipes (CMP). Rainfall runoff
from the coal pile and coal handling areas and portions of the plant yard goes to
the yard sumps that discharge to the ash basin. Storm water runoff from other
areas of the site is discharged to the Catawba River and the South Fork River.
Rainfall runoff from the transformer yard area and the 115 KV switchyard is
routed through oil trap tanks prior to being discharged.
3.3 Characterization of Drainage Basins
A description of the drainage area, significant materials, and material control
measures is presented for each drainage basin. Herbicides are spot applied
where required in parking areas, switchyards, parts laydown areas, along
walkways, and around various fixtures and buildings.

identified under Table 2c-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 very low levels of a
substance found in Table 2c-3. It is not anticipated that these products will

5.0 Allen Steam Station 316 Determination
5.1 Allen Steam Station 316(a) determination
Duke Power Company's 316(a) demonstration (March 1976) concluded that the
"heated discharge from Plant Allen is such that the protection and propagation of
a balanced indigenous aquatic community in and on Lake Wylie is assured."
Duke's operation experience during the past five years under the thermal
limitations imposed in NPDES Permit No. NC0004979 substantiates the above
conclusion and further supports Duke's belief that the operating characteristics of
the station have a minimal effect of the aquatic environment of Lake Wylie.
Surveys of the aquatic community in Lake Wylie demonstrate that a Balanced
Indigenous Population exists in Lake Wylie. Accordingly, Duke requests a
316(a) variance and further requests that the thermal limitations imposed in the
permit be continued.

Plant Allen,Gaston County
NPDES Permit No.NC0004979
Page 25 of 26
5.2 Allen Steam Station 316(b) Determination
In conjunction with the rulemaking process for the new Phase II 316(b) rule
pertaining to fish impingement and entrainment, historical data and permitting
records were reviewed. Initial 316(a) and 316(b) studies associated with
enactment of the Clean Water Act concluded that the location, construction
capacity, and design of the cooling water intake of Allen and other Duke Power
steam stations were not detrimental to the aquatic ecosystem and minimize
adverse environmental impacts. Both North Carolina and -EPA regulators
concurred in 1976 that 316(b) fish impingement and entrainment studies were no
longer needed at that time. Although the new Phase II 316(b) rule for existing
facilities is currently being litigated, plans for information collection (PICs) are
being developed to conduct a Comprehensive Demonstration Study (CDS) to
determine required measures to be implemented per approval of NCDENR.

PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. Existing treatment facility
a. Current permitted capacity: Flows are intermittent in nature.
b. Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: No ATCs issued to this facility within the past two years.
c. Actual treatment capacity of the current facility (design volume in MGD): _
Outfall 001 Outfall 002 Outfall 003 Outfall 004
784.8 11.6 6.3 8.0
d. Description of existing or substantially constructed WWT facilities: outfall 001-
there are no existing WWT facilities; outfall 002 - permittee operates a septic
tank/sand filter WWT treatment system for treatment of all domestic wastewater.
The effluent from the septic tank/sand filter then enters an earthen(ash) settling
basin with pH adjustment prior to discharge; outfall 003 - There are no existing
WWT facilities; outfall 004 - There are no existing WWT facilities. The permittee
also operates a raw water treatment system involving sedimentation, filter back
wash, and demineralization. Discharges from the various raw water treatment
processes (as well as any residuals generated) are sent to the ash basin. The raw
water is not used for drinking,but rather in-plant process use.
2. Type of proposed treatment facility: The applicant proposes to construct a chemical
injection system for treatment of pollutants that will not settle out in the existing ash
basin settling cells. This system will involve the division of a portion of the existing fly
ash basin into a series of three (3)primary settling cells. During any given period of time,
each cell will be alternated during plant operation with one receiving the primary sluice
wastewater flow while the other two operate in a drying or excavation mode (ash
removal). From the primary settling cells,the wastewater will flow through what is being
referred to as a"treatment channel"where any chemical injection that may be necessary
will occur. In this channel, a portion of the flow will be analyzed for pH, and if
necessary, ferric sulfate and/or sulfuric acid will be added as needed for pH control and to
augment precipitation of other constituents of concern(primarily selenium). From the
treatment channel,the wastewater will flow into a final settling or flocculation cell. This
cell will help capture any solids that may not be removed in either the primary cells or the
treatment channel. Overflow from this cell will then flow across a vegetated ash delta
prior to discharge to the main ash pond. Duke also plans to install the capability of
bypassing the main ash pond should effluent quality not require the additional polishing
that the main ash basin would provide or should conditions in the main ash pond be
detrimental to effluent quality (such as an algae bloom).

3. Residuals handling and utilization/disposal scheme: Ash is removed as needed from the
ash basin, stockpiled for drying, and then reused in accordance with the terms and
conditions of Duke Power's Ash Reuse permit.
4. Treatment plant classification: Class I
5. SIC Code(s): 4911 Wastewater code(s): 68, 66 Main Treatment Unit code: 50002
6. Important SOC/JOC or compliance schedule dates: This facility is neither under an
SOC nor is one being considered at this time.
PART III - EVALUATION AND RECOMMENDATIONS
The applicant, Duke Energy, Inc. (Duke), has requested the issuance of an ATC for the
construction and modification of the existing ash treatment and disposal system at Duke's Allen
Steam Station. These modifications are necessary in order for Duke to maintain compliance with
the company's NPDES permit. Specifically, Duke has experienced difficulty in complying with
pH and selenium limitations.
In July 2003, Duke was.granted approval to conduct a pilot study where flow
modifications to the existing ash basin allowed Duke to maintain compliance with the permit
limitation for selenium while allowing Duke staff to collect operational data that will help them
implement a permanent solution. In October 2003, Duke requested an extension of the pilot
study in order to finalize the data they had acculmulated, and begin the process of designing a
permanent solution. This Office granted an extension of the pilot study for an additional six (6)
months ending April 30, 2004. Since the actual request for the ATC was not received by the
Division until March 26, 2004, Duke requested and received(by email) an extension of the pilot
study until such time as the Division issues the ATC.
Pending a fmal technical review and approval by the NPDES Unit, it is recommended
that an ATC be issued as requested.

1.0 Proposed Changes Incorporated Into Permit Renewal
• Change WET testing requirement from 16%effluent concentration to 24%.
• Remove monitoring requirements for BOD,fecal coliform,and phosphorus.
• The quarterly monitoring requirements will be removed for barium,cadmium,chromium,
cyanide,naphthalene,nickel,phenols,zinc,and sulfates. None of these pollutants were
presents in levels that could reasonably be expected to cause an exceedance of water quality
standards.
• An arsenic limit of 42 pg/L will be added to the permit. Two values measured in 2003 were
above the allowable concentration of 42 pg/L.
• The facility will receive a weekly average selenium limit of 21 pg/L.
• 316(b)special condition will be added.
2.0 Summary
Duke Energy's Allen Steam Station is a coal fired steam electric plant in Gaston County.
Effluent Guidelines are provided in 40 CFR 423.12. The facility is also subject to the Cooling
Water Intake Structure Rule(316(b)Rule)per 40 CFR 125.95. A special condition will be added
expressing this requirement.
The facility has four permitted outfalls in the current NPDES discharge permit,issued in
September 1996.
> Outfall 001 is comprised of once through,non-contact condenser cooling water. The
average flow through this outfall,is 626 MGD(from permit application). This outfall
discharges to the South Fork Catawba River.

NPDES Permit Fact Sheet—09/27/05 Duke Power/ Allen Steam Station
Page 2 NC0004979
> Outfall 002 is the ash basin discharge. In 1996 the average discharge from this outfall
was 11.6 MGD,however current discharge rates average 19 MGD. This outfall
discharges to the Catawba River.
> Outfalls 002A and 002B are intermittent discharges of emergency overflows(coal yard
sump overflow and power house sump overflow,respectively). Both outfalls
discharge to the Catawba River.
> Outfall 003 is miscellaneous once through non-contact cooling water. This outfall
discharges to the South Fork Catawba River and averages 4.5 MGD(from permit
application).
> Outfall 004 is also miscellaneous once through non-contact cooling water. This outfall
discharges to the Catawba River and averages 6.5 MGD(from permit application).
> During the previous renewal,the facility received authorization to backwash an intake
filter for Unit 5 condenser cooling water on an as-needed basis. The wash waters
contain materials indigenous to the Catawba River such as Asiatic Clams and light
debris. There is a special condition in the permit allowing for this discharge.
In 1995 the facility completed construction of a Chemical Injection Facility for the ash basin. The
purpose of this project was to assist with the settling of selenium and other pollutants that were
not being removed from the effluent. This project consisted of the construction of three primary
settling cells,a treatment channel,a chemical injection system(ferric sulfate to enhance selenium
precipitation)and a final settling/flocculation cell.
In the renewal application,Duke Power requested the following changes to their permit.
1. The elimination or reduction of outfall 002 monitoring requirements for the following
parameters:barium,BOD,cadmium,chromium,copper,cyanide,fecal coliform,
naphthalene,nickel,phenol,phosphorus,sulfate,and zinc.
2. That the selenium limit be changed from a daily maximum limit to a monthly average
limit based on an interpretation of 40 CFR 131.36.
The facility also requests a continuation of the thermal limitations present in the permit. The
facility has a 316(a)variance for outfall 001 and submits a yearly Balanced and Indigenous
Population report in compliance with the variance. Permit modifications issued in 2003 clarify
the temperature limit as being a monthly average effluent limitation,as opposed to a daily
maximum limitation.
As part of the permit application,Duke Power submitted EPA Forms 1,2C,and 2F. Form 2F
was filled out for two stormwater outfalls:008 and 015.
3.0 Compliance Summary
Instream Data
The facility submitted the most recent Assessment of Balanced and Indigenous Populations In
Lake Wylie Near Allen Steam Station report,developed in November 2004. This annual
monitoring requirement began in 1990 as the result of an agreement between the Division and
Duke Power to support the facility's 316(a)thermal variance. This study appears to concur with

NPDES Permit Fact Sheet—09/27/05 Duke Power/Allen Steam Station
Page 3 NC0004979
past studies in that Lake Wylie has a balanced indigenous fish community. No other instream
monitoring is required as part of the NPDES permit.
DMR Data Review
DMRs were reviewed for outfalls 001,002,002A,002B,003 and 004 for the period of January 2002
through July 2005.
At 001,the average flow over the review period was 581 MGD with a maximum flow of 784
MGD. The average daily temperature at this outfall was 82°F with a maximum daily
temperature of 111°F. The discharge remained in compliance with its effluent limitations.
Outfalls 002A and 002B have not discharged during the last permit cycle.
Only flow is required to be estimated at outfall 003. The average flow estimate during the review
period was 4.5 MGD.
Only flow and oil and grease are required to be monitored at 004. Flow estimates during the
review period averaged 6.5 MGD. O&G values averaged<5.0 mg/L with a maximum of 5.0
mg/L.
The following table summarizes DMR data for non-toxicants at outfall 002. RPAs were
performed for toxicants and metals(results discussed in the following section).
Parameter Average.. :. ;,Maximum Minimum
Flow(MGD) 18.92 34.1 0.7
BOD(mg/L) <2.0 2.0 <2.0
pH(s.u.) 6.8 9.3 6.1
Fecal coliform(#/100mL) <2.0 22 <2.0
TSS(mg/L) 10 28 <4.0
Oil and Grease(mg/L) <5 5 <5
Total Nitrogen(mg/L) 0.52 0.99 0.26
Total Phosphorus(mg/L) <0.010 0.02 <0.010
The only violation for the above monitored parameters was for pH. In July,2003 the facility
recorded a pH value of 9.3,which exceeds its permit limit of 9.0 s.u..
Based on the above data,the facility requests removal of the monitoring requirements for BOD,
fecal coliform,and phosphorus. All of those parameters had quarterly or semi-annual
monitoring in the previous permit. Based on the data,it appears that effluent levels of these
parameters are not sufficient to cause an adverse impact to water quality. Monitoring will be
removed.
RPA Analysis
RPAs were performed for arsenic,barium,cadmium,chromium,copper,cyanide,iron,
naphthalene,nickel,phenols,selenium,zinc,and sulfates. Since the facility does not have a
permitted flow,past RPAs were conducted using the monthly average flow instead of permitted
flow. That methodology was retained in this renewal. In 1996 the average flow was 11.6 MGD.
Current average flows at outfall 002 are 19 MGD.

NPDES Permit Fact Sheet—09/27/05 Duke Power/ Allen Steam Station "
Page 4 NC0004979
The quarterly monitoring requirements will be removed for barium,cadmium,chromium,
cyanide,naphthalene,nickel,phenols,zinc,and sulfates. None of these pollutants were present
in levels that could reasonably be expected to cause an exceedance of water quality standards.
Iron monitoring will remain in the permit due to the requirements of 40 CFR423.12. The permit
limit is higher than the 1.0 mg/L recommended by 40CFR due to a past agreement between Duke
Power and the Division to adjust the limit based on high levels of iron in the source water.
An arsenic limit of 42 pg/L will be added to the permit. Two values measured in 2003 were
above the allowable concentration of 42 pg/L.
The previous permit had a selenium limit of 31 pg/L. The facility violated this limit in July,2003.
Based on the change in IWC during this renewal,the new permit will have a selenium limit of 21
pg/L. The facility has requested that this limit be expressed as a monthly average based on EPA
guidance. Duke argues that the current limit is based on a CCC for selenium of 5 pg/L and EPA
directs for CCCs to be expressed as a monthly average limit. NC also has a selenium aquatic life
criterion of 5.0 .ig/L. According to Division policy,this criterion can be expressed as a weekly
average limit. Therefore the facility shall receive a weekly average selenium limit of 21 pg/L
during this renewal.
40 CFR 423.12 requires a copper limit of 1.0 mg/L. Therefore the copper limit will be retained in
this renewal.
WET Test Results
The IWC used for WET testing was 16%in previous permits. That value was based on an
average discharge of 11.6 MGD. Currently,the discharge at outfall 002 averages 19 MGD.
Therefore the WET testing requirement will be changed to reflect the 24%IWC.
The Allen Steam Plant passed 21/23 chronic WET tests administered from January 2001 through
July 2005. There were two total failures: one in October 2001 and another in October 2003. The
facility passed two consecutive tests administered following each failure.
Correspondence File Review/Compliance History
There were two daily maximum permit violations over the 2002-2005 data review period. One
was for pH(reported value of 9.3 s.u.)and the other was for selenium(reported value of 40.4
pg/L). Both violations occurred during the same month(July 2003). Inspection and staff reports
note that the facility is consistently well operated and maintained.

Subject: Draft NPDES Permit
Permit NC0004979
Allen Steam Station
Gaston County
Dear Mr.Ruhe
Enclosed with this letter is a copy of the draft permit for your facility.Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
➢ Since your facility does not have a flow limit,the average discharge volume at outfall 002 has
historically been used to calculate permit limits and WET testing requirements. In 1996 that average
flow was 11.6 MGD yielding an instream waste concentration(IWC)of 16%. Currently,your flows
are averaging 19 MGD. Therefore the IWC used to calculate your permit requirements(including
WET testing requirements)has been changed to 24%.
➢ Monitoring requirements for BOD,fecal coliform,and phosphorus have been removed due to the low
levels historically present in your discharge.
➢ Monitoring requirements for barium,cadmium,chromium,cyanide,naphthalene,nickel,phenols,
zinc,and sulfates have also been removed. None of these pollutants were present in levels that could
reasonably be expected to cause an exceedance of water quality standards.
➢ An arsenic limit of 42 pg/L has been added to the permit. Two values measured in 2003 were above
the allowable concentration of 42 pg/L.
➢ Based on your comments and Division policy,the selenium limit has been changed to a weekly
average limit. You requested that this limit be changed to a monthly average requirement based on
EPA guidance for calculating CCC-based limits,however NC water quality standards have a
selenium aquatic life standard of 5.0}tg/L. Our policies allow for this to be expressed as a weekly
average,not monthly average. In addition,this limit has been reduced to 21 pg/L due to your
facility's higher IWC.
➢ A special condition has been added regarding the requirement to comply with the Cooling Water
Intake Structure Rule per 40 CFR 125.95(section 316(b)requirements)
Submit any comments to me no later than thirty days following your receipt of the draft.Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from
the public or from you,this permit will likely be issued in two months.

Permit NC0004979
A. (8.) CHRONIC TOXICITY PASS/FAIL PERMIT LINIIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 24%.
The permit holder shall perform at a minimum, quarterlq monitoring using test procedures outlined
in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998,
or subsequent versions or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised-February 1998) or subsequent versions. The tests will be performed during the months
of January,April,July and October. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple-concentration testing shall be performed at a minimum,
in each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention:North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and
all concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT)
test form indicating the facility name, permit number, pipe number, county, and the month/year of
the report with the notation of"No Flow" in the comment area of the form. The report shall be
submitted to the Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality 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, minimum control organism reproduction, and appropriate environmental
controls, shall constitute an invalid test and will require immediate follow-up testing to be completed
no later than the last day of the month following the month of the initial monitoring.

Permit NC0004979 ,
A. (9.) BIOCIDE CONDITION
The permittee shall not use any biocides except those approved in conjunction with the permit
application. The permittee shall notify the Director in writing not later than ninety (90) days prior to
instituting use of any additional biocide used in cooling systems which may be toxic to aquatic life
other than those previously reported to the Division of Water Quality. Such notification shall include
completion of Biocide Worksheet Form 101 and a map locating the discharge point and receiving
stream. Completion of Biocide Worksheet Form 101 is not necessary for those outfalls containing
toxicity testing. Division approval is not necessary for the introduction of a new biocide into an
outfall currently being tested for toxicity.
A. (10.) SPECIAL CONDITIONS
The following special conditions are applicable to all outfalls regulated by NC0004979:
• There shall be no discharge of polychlorinated biphenyl compounds.
• It has been determined from information submitted that the plans and procedures in place at
Allen Steam Station are equivalent to that of a BMP.
• The permittee shall report the presence of cenospheres observed in any samples.
• The applicant is permitted to discharge chemical metal cleaning wastes to the ash basin under
the conditions outlined in the 1976 Riverbend Ash Basin Equivalency Demonstration and the
1994 Allen Steam Station permit application
• The permittee shall check the diked areas for leaks by a visual inspection and shall report any
