NPDES Permit Application Amendment — Reverse Osmosis Filtration System
Dear Mr Goodrich
CP&L dba Progress Energy Carolinas, Inc will soon complete a trial run of a Reverse Osmosis
(RO) filtration unit (approved via email by Tom Belnick, NPDES unit, on March 21, 2004) at the
Weatherspoon Steam Electric Plant The plant would like to operate this RO on a permanent
basis following the trial and will leave the unit in service in its current capacity
Reverse osmosis uses a membrane that is semi -permeable, allowing the fluid that is being
purified to pass through it, while refecting the contaminants that remain Most reverse osmosis
technology uses a process known as crossflow to allow the membrane to continually clean
itself As some of the fluid passes through the membrane the rest continues downstream,
sweeping the refected species away from the membrane
Previously, the Weatherspoon Steam Electric Plant used demineralizers to purify well water for
use in plant systems The RO system will be used to filter the well water prior to entering the
demineralizers reducing regeneration of the demineralizers from approximately 3 times per
week to approximately 10 times per year Low volume waste associated with demineralizer
regeneration is expected to be reduced from 120 GPD to 100 GPD (See Attachment 2).
Chemical reductions of sodium hydroxide (9,000 gals/yr to 360 gals/yr) and sulfuric acid (2,000
gals/yr to 75 gals/yr) are also expected (See Attachment 4) An antiscalant and flocculant will
be added during the operation of the RO The RO membrane will be cleaned approximately 4
times per year with 2 additional chemicals used at the time of cleaning (See Attachment 4)
In reverse osmosis treatment, the supply water is typically cycled up to four (4) times its normal
concentration before being discharged from the unit This water (Reverse Osmosis refect
water) would then be sent directly to the 225 acre off -stream cooling pond Releases from the
cooling pond (Outfall 001) are rare, occurring usually when a mayor storm is expected and
additional freeboard is needed to prevent overtopping of the pond dikes (see Attachment 3)
Based on the proposed design for this system, this RO refection water flow rate would be about
4,000 gallons per day
Because of the addition of the RO, the Weatherspoon Plant wishes to amend the current
NPDES Permit Application to include this new low volume wastestream. Enclosed are

Lumberton, NC 28358

amended Attachments 1, 2, 3, and 4 of the NPDES permit application and the MSDS sheets for
the water treatment additives in Section 5 of Standard Form C-RO
This wastesteam is considered to be a low volume waste and is currently addressed by the
permit We therefore do not believe that a permit modification is needed If your office believes
this otherwise please contact us.
If you have any questions regarding any information in this submittal please call Rodney
Lemonds at [phone].

Attachment 3
Form 2C - Item II -B Flows, Sources of Pollution, and Treatment Technologies
The Weatherspoon Plant is a coal-fired steam cycle electric generating plant with three units Four
Internal Combustion (IC) Turbines are also located on the plant site The plant has a 225 -acre off stream
cooling pond on the north side of the Lumber River in Robeson County, North Carolina Water is
withdrawn from the Lumber River as required to make up evaporative and seepage losses from the
cooling pond Water for plant use is also withdrawn from wells Makeup pumping rates from the river are
highly variable depending upon natural weather conditions, generation load, plant operations, and cooling
pond water level
Chemical constituents contained in both of these discharges will, in part, be representative of the naturally
occurring chemical quality of the intake water and will also have chemical constituents of such quality and
quantity associated with similar discharges for fossil generating facilities of this size, type, and in this
geographical location Either all or part of the elements enumerated in the Periodic Table, either singularly
or in any combination, may from time to time be contained in this discharge Each component of the
discharges is described below
OUTFALL 001 - DISCHARGE FROM COOLING POND
Plant waste streams are routed directly or indirectly to the cooling pond and thereby recycled Releases
from the cooling pond (Outfall 001) are rare, occurring usually when a mayor storm is expected and
additional freeboard is needed to prevent overtopping of the pond dikes On other occasions, the pond
may need to be drawn down for maintenance purposes The cooling pond last discharged to the Lumber
River in September of 1999 The permit required analyses were performed on the discharge and
submitted in the September 1999 Discharge Monitoring Report (DMR) The pH of the cooling pond is
neutralized when needed by adding acid or caustic at the discharge of the circulation water pumps A
description of the waste streams that discharge into the cooling pond follows
RECIRCULATED COOLING WATER
This flow provides condenser cooling water for the three generating units The flow is discharged
into the pond and routed through the pond by baffle dikes to achieve maximum surface cooling
efficiency before reaching the condenser cooling water intake structure to be used again Cooling
of the pond is achieved primarily by evaporation from the pond surface, which is estimated to
consume a maximum of approximately 1 6 MGD above natural evaporation rates during times the
units are in full operation Control of biological fouling on condenser surfaces is accomplished by
chlorinating as required
COAL PILE RUNOFF
Rainfall runoff from the coal pile (approximately 6 acres) is routed to the cooling pond, which
provides treatment by neutralization and sedimentation
STORMWATER RUNOFF
Rainfall runoff from the industrial portion of the site is ultimately routed to the cooling pond
Sludges/sediments collected in sumps, catchment basins, etc are disposed of in the ash pond or
by other appropriate methods
ASH SLUICE WATER
Fly ash and bottom ash from all three units is hydraulically conveyed by an ash sluice pipeline to
the ash pond In addition, water from washing the interior of the precipitators is sent to the ash

Progress Energy Carolinas, Inc.
Weatherspoon Steam Electric Plant
National Pollutant Discharge Elimination System Permit Number NC0005363
pond via the ash sluice pipeline A stand pipe allows for overflow release to a small secondary
settling basin containing another stand pipe for release to the cooling pond
DOMESTIC WASTES
Sanitary wastes are treated on-site by a septic tank and a sand and gravel drainage field which
discharges to the cooling pond Flow from the system is dependent upon fluctuating demand due
to variations in the number of personnel on site When needed, residuals are disposed of off-site
by a licensed contract disposal firm
CHEMICAL METAL CLEANING WASTES
Wastes from the chemical cleaning of the boiler tubes are normally disposed of by evaporation in
boilers, either onsite or at another Progress Energy facility Boiler cleaning is usually performed
every 10 years Units 1 and 3 boder cleanings are currently scheduled for spring 2008 and 2004,
respectfully Should boder cleaning wastes not be evaporated, they will be treated by
neutralization and precipitation in portable holding tanks The liquid fraction of the metal cleaning
wastes will be discharged to the ash pond The sludge fraction of the metal cleaning wastes will
be disposed of in either the ash pond or by other appropriate methods In addition, wastes from
the chemical cleaning of the condenser tubes and heat exchangers are normally disposed of in
the ash pond Should condenser and heat exchanger cleaning wastes not be discharged into the
ash pond, they will be evaporated At this time it is unclear as to how often condenser and heat
exchanger cleaning may be performed Currently, Unit 3 heat exchanger cleaning is scheduled
for April 2004
IC TURBINE SITE
There are four Internal Combustion (IC) Turbines located at the Weatherspoon Plant All drains
from the IC turbine site, including drains collecting rainfall, are routed through an oil -water
separator which discharges to the cooling pond Sludges/sediments collected in sumps,
catchment basins, etc are disposed of in the ash pond or by other appropriate methods.
AIR PREHEATER WASHES
The air preheaters are water washed infrequently When the air preheaters are washed
approximately 50,000 gallons of wastewater is produced and discharged to the ash pond via the
ash sluice pipelines
SPENT SANDBLAST MATERIAL
Periodically, sections of boilers, turbines and miscellaneous parts require sandblasting The
sandblasting process produces approximately 500 to 700 pounds of spent material annually This
material is discharged to the ash pond via the ash sluice lines or by other suitable methods
depending on work location
LOW-VOLUME WASTES
Waste streams not identified above fall in the category of low volume wastes All low volume
wastes described below are routed by gravity flow to the cooling pond. Sumps convey
miscellaneous equipment leakage, equipment drainage for maintenance, equipment wash down
water, sampling streams, and closed cooling water system blowdown Water treatment wastes
consist of solutions of sodium chloride, used for water softener regeneration, and sodium
hydroxide and sulfuric acid which are used in the regeneration of demineralizers Demineralizer
regeneration wastes are routed to the ash pond via the ash sluice line RO refect water and
cleaning solutions, and water softener regeneration wastes are routed directly to the cooling pond
Blowdown of boder water to control boiler chemistry is routed to a flash tank, which discharges to
the cooling pond. Drains from areas likely to contain oil filled equipment or storage are routed
through an oil -water separator Sludges/sediments from sumps, catchment basins, etc are

disposed of in the ash pond or by other appropriate methods. A summary of process chemicals is
provided in Attachment 4
In many cases, chemicals added during the plant processes are consumed or chemically altered
Only trace amounts might be recoverable in water entering the cooling pond Because the cooling
pond serves as a final treatment basin and receives significantly greater volumes of water from
other inflows, detectable levels of these chemicals should not occur in the cooling pond discharge
ASH MANAGEMENT AND RECLAMATION
From time to time fly and bottom ash in the ash pond may be stacked or relocated within the diked
boundary of the ash pond system As this pond management activity does not alter the chemical
character of the pond contents, no change in the nature of the discharge to the cooling pond is
anticipated
In the event a practicable market becomes available, Progress Energy Carolinas may exercise the
option of reclaiming ash from the ash pond system In consideration of the scope of such an
operation, no additional discharges are expected to result from ash reclamation efforts
HERBICIDE AND PESTICIDE USAGE IN THE TREATMENT SYSTEM PONDS
Herbicides may be used as needed to control nuisance aquatic vegetation These herbicides are
applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator, in accordance with the manufacturer's instructions
Pesticides may be used as needed to perform biological assessments These Pesticides are
applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator, in accordance with the manufacturer's instructions
OUTFALL 002 - SERVICE WATER
NON -CONTACT COOLING WATER
Non -contact cooling water is withdrawn from the Lumber River and passed through heat
exchangers to provide non -contact cooling for the Plant's closed cooling water system After
passing through the heat exchanger, non -contact cooling water is routed either to the cooling
pond or to the Lumber River via outfall 002 depending on the need for cooling pond makeup
water
Sodium hypochlorite (chlorine) is added at the non -contact cooling water pump intake, as
required, to control biological fouling of the heat exchanger surfaces As established by written
plant procedure, chlorine is only added during times where non -contact cooling water is routed to
the cooling pond Upon completion of chlorine addition, the non -contact cooling water system is
operated with discharge to the cooling pond for a period of at least one hour prior to any
redirection to outfall 002 This procedure has been implemented to prevent the discharge of
chlorine to the river via outfall 002
