Permit NC0080781
A. (2) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 23%.
The permit holder shall perform at a minimum,quarterly 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 once during each calendar quarter. 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: NC DENR/DWQ/Environmental Sciences Section
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(Al) 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.
If the Permittee monitors any pollutant more frequently then required by this permit,the results of such monitoring
shall be included in the calculation&reporting of the data submitted on the DMR&all AT Forms submitted.
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.

Subject: Draft NPDES Permit
Permit NC0080781
Lincoln Combustion Turbine Plant
Lincoln County
Dear Mr. Ruhe:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully so
that you thoroughly understand the conditions and requirements it contains.
Your permit is among several in the Catawba River basin the Division has targeted for expedited renewal. No
major changes have taken place to the Division's management strategy for the Catawba River. The Division
can therefore expedite renewal of permits in the Catawba River basin whose operations have not changed
since the last permit renewal, and whose compliance records are in good standing.
A Total Residual Chlorine (TRC) limit has been added to this permit. Because the subject facility is equipped
with a dechlorination system, the TRC limit will take effect with the effective date of the final permit. Please
refer to the enclosed TRC policy memo for details.
Submit any written comments to me at the letterhead address no later than thirty (30) days following your
receipt of the draft permit. If the Division does not receive any adverse comments from either you or the
public within this designated time, our office will likely issue the final permit in early April, with an effective
date of May 1, 2005.
If you have any questions concerning this draft permit, contact me at [phone], extension 532 or via
email at "[e-mail]".
Sincerely,
leg,..o....,...,__

TO: NPDES Unit Staff
FROM: David A. Goodrich
NPDES Unit Supervisor
SUBJECT: Total Residual Chlorine Policy for NPDES permits
Every three years the State is required by the Clean Water Act to review its surface water quality standards and
classifications,determine if changes are needed and to make any necessary changes. This review process is referred to
as the "triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface
water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before
the state's Environmental Management Commission on October 10,2002.
The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic,Cyanide,
Methylene Blue Active Substances (MBAS) and Total Residual Chlorine (TRC). The Hearing Officer also
recommended the addition of a standard for Methyl Tert-Butyl Ether(MTBE).
All of the Hearing Officer's proposed changes were adopted with the exception of MTBE. The changes took effect
on April 1,2003. This memo documents the changes to the NPDES permitting policy for TRC limits.
Total Residual Chlorine (TRC)
Previously,TRC had an Action Level Standard,except in designated Trout waters. The Triennial Review changes
modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/L. The Aquatic Life Standard will
remain for designated Trout waters.
Aquatic Life Standard— 17 µg/L (freshwater only) Trout Waters— 17 µg/L
Revised TRC Policy
➢ TRC limits will be assigned to permit renewals and all new permits issued after April 1,2003.
> Facilities that do not use chlorine will not receive a TRC limit;however,the presence of a chlorine back-up
system to augment UV or other disinfection requires a TRC limit.
> Facilities discharging to streams with a 7Q10 <0.05 cfs (zero-flow streams)will receive a limit of 17 pg/L.
> Limits will be capped at 28 µg/L to protect against acute impacts.
It is likely that many facilities will need to add dechlorination(or use another means of disinfection) to comply with
the new TRC standard. Therefore,a compliance schedule of 18 months from the effective date of the permit may
be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the
facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES
Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment.

1. a. Volume of wastewater: 0.09505 MGD (Design Capacity)
b. What is the current permitted capacity: 0.09505 MGD
e. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of four(4) oil water separators followed by an aeration tank,
a two cell settling pond (250,000 gallons each), and pH neutralization. The
oil/water separators collect water from various turbine processes including
miscellaneous piping leaks, wash down water, and stormwater runoff. The
discharges from the four oil/water separators enter into an aeration tank, which
collect wastewater from the turbine yard sumps, maintenance/warehouse sump, and
the vehicle wash. From the aeration basin, all wastewater flows into the two settling
cells.
The two settling cells receive wastewater from the combustion turbine sumps (see

PART IV- EVALUATION AND RECOMMENDATIONS
Duke Energy Corporation(DEC)requests renewal of the NPDES Permit for the Lincoln
Combustion Turbine Plant(LCTP) in Lincoln County. There have been no changes to the WWT
facility and/or the permit since the permit was last renewed. Wastewaters produced at this facility
consist of raw water processed for use in the combustion turbine operations and in-plant processes.
In discussion with DEC staff regarding this renewal, it was learned that the discharge from
the LCTP would likely be eliminated by the middle to end of next year(2010). DEC sold a portion
of the property at the LCTP to Lincoln County, who is in the process of constructing a new POTW
(Killian Creek WWTP -NC0088722) at the LCTP site. Construction of the Killian Creek WWTP
is underway, and the County hopes to have the plant operational sometime in 2010. The LCTP will
be one of the first customers connected to the new WWTP given its proximity to the site.
Until such time as the new POTW is completed and placed into operation, the subject permit
will have to be reissued. Therefore,pending receipt and approval of the draft permit, it is
recommended that the permit be renewed as requested.

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.

NPDES Supplemental Information for
Lincoln Combustion Turbine
NPDES Permit No. NC0080781

Lincoln Combustion Turbine, Lincoln County
NPDES Permit No.NC0080781
Page 2 of 9
General Site Information
The Lincoln Combustion Turbine (LCT) site consists of sixteen combustion turbine
generator units that supply 74 Megawatts per unit for a total of 1,184 Megawatts. The
Lincoln facility serves as a primary source of power during peak demand periods, and
also during times when energy from other sources may be unavailable. The greatest
electrical demand is usually in the summer and winter months. Each combustion
turbine can be operated independently and for extended periods of time if necessary.
Combustion turbines burn #2 low-sulfur fuel oil or natural gas to heat compressed air,
which expands and drives a turbine-generator to produce electricity. Construction of
the LCT units was completed in March of 1996.
The attached schematic illustrates the water flow through LCT, indicating the source of
intake water, operations contributing to the effluent, and the wastewater treatment
provided. The estimated flows on the line drawing are representative of present station
operation. The following is a brief narrative description of sources contributing to the
wastewater effluent of outfall 001.
Intake
Raw water is withdrawn from Killian Creek and stored in the 50 million gallon Raw
Water Storage Pond. The pond is equipped with an overflow pipe to wetlands, which
flows into Killian Creek. The raw water intake screens are sparged with air periodically
to remove trapped creek debris. This debris is flushed back into the creek. Dredging of
the intake is done periodically in accordance with the ACOE 404 permit (#199404202).
From this pond, raw water is processed by the filtered water and demineralized water
treatment systems in order to purify service water for combustion turbine operations
and plant processes. The wastewater and chemicals generated by these processes
are discharged to the wastewater treatment system at the LCT site.
Outfall 001 - System Description
Outfall 001 discharges treated wastewater from the Wastewater Treatment (WT)
system through a flume to Killian Creek below the LCT site. The WT system basin
consists of two parallel concrete lined treatment cells (250,000 gallons each). The
treatment basin provides a common mixing point for all site wastewater. Discharge
from the basin is on a batch basis and is neutralized as needed while discharging.
The wastewater treatment system provides settling and neutralization prior to
discharge. This basin processes wastewater flows from the water treatment system
and an aeration tank, which collects wastewater from four turbine yard sumps,
maintenance/warehouse sump and the vehicle wash. The total combined effluent from
these sources is approximately 0.30 Million Gallons per Day (MGD). Wastewater from
the WT treatment system is discharged to Killian Creek at Outfall 001.

Lincoln Combustion Turbine, Lincoln County
NPDES Permit No.NC0080781
Page 3 of 9
Filtered Water System
Flow from the Raw Water Storage Pond is directed to the filtered water system where it
is treated for process use. The filtered water treatment system at LCT consists of a
clarifier, three gravity sand filters and a clear well. Wastewater and raw water solids
from the filtered water system are drained to the wastewater treatment basin, which
provides settling treatment.
Clarifier
The clarifier utilizes typical water treatment chemicals such as cationic
polyelectrolyte, clay, and gaseous chlorine for the primary treatment of raw water.
The sedimentation wastes collected in the clarifier consists of solids that were
suspended in the service water.
Just prior to the flash floc tank, gaseous chlorine is injected into the raw water. The
cationic polyelectrolyte is added from a unit called a "Poly Flow". This unit receives
dilution water from a filtered water compression skid and injects the polyelectrolyte
into the flash floc tank. Also, the clay receives dilution water from the filtered water
compression skid and the clay slurry is pumped into the flash floc tank.
Approximately 110 gallons per year of polyelectrolyte may be used. The average
volume of water required for desludging the clarifier is between 10,000 - 20,000
gallons per day. Typically, these sedimentation wastes (which consist of mud, silt,
clay and flocculent precipitate) along with diluted water treatment chemicals and by-
products, gravity flow from the bottom of the clarifier and are collected in the
wastewater treatment basin.
Gravity Filters
There are three gravity sand filters composed of anthracite (coal) and sand,
downstream of the clarifier in the water treatment process. Normally, each of these
filters is backwashed two to five times each day during peak operation. Each
backwash uses about 10,000 gallons of water. On the average, 90,000 gallons of
backwash water is produced daily from filter backwashes.
This wastewater drains to a cement trench that discharges to the wastewater
treatment basins. The sand filters are changed on an as needed basis. The filtered
water is stored in one of two 400,000 gallon filtered water tanks (A and B). Of this
total volume of water, 300,000 gallons are designated for fire protection usage.

NPDES Permit No.NC0080781
Page 4 of 9
Demineralized Water System
The Demineralized Water System provides high purity water which is injected into the
combustion turbines for nitrous oxide (NOx) control. The demineralized water is also
used for miscellaneous plant usage such as housekeeping, turbine deck wash water
and cooling water makeup.
Activated Carbon Filters
The Demineralized Water System includes three, 235 ft3 carbon filters. These filters
are typically backwashed weekly. The amount of water required to backwash one of
these filters is approximately 10,000 gallons of water per backwash. Backwashes
may occur daily or weekly, depending on station operation. The carbon is
replenished as needed and the spent carbon is routed to the wastewater treatment
basin.
Demineralizers
There are three trains of resin bed regenerative demineralizers. Each train consists
of one anion resin bed and one cation resin bed. Normally, one to three trains of
demineralizers are in operation. The demineralized water produced is stored in two
demineralized water storage tanks (A and B) which have a capacity of 1.4 million
gallons each.
Regeneration of one anion/cation demineralizer train may occur as often as once
per day. A typical regeneration of one train takes approximately 50,000 gallons of
water. The amounts of required acid and caustic will vary as dictated by operational
requirements.
Wastewater from these regenerations is discharged to a 150,000 gallon
neutralization tank. The wastewater is neutralized prior to discharge to the
wastewater treatment basin. The acid and caustic used in the neutralization
process are stored in day tanks. The acid day tank contains 380 gallons and the
caustic day tank conatins 730 gallons. In the event of a leak from the day tanks, the
acid or caustic would be neutralized and drained to the wastewater treatment
basins. The capacities of the bulk sulfuric acid and the sodium hydroxide tanks are
4,000 and 4,500 gallons respectively.
Combustion Turbine Sumps
The four turbine sumps are concrete structures which have two pumps per sump.
These pumps are operated on an alternating basis. After a preselected time period, the
controls are automatically cycled so the pump operation is swapped.
The turbine sumps collect wastewater from four oil/water separators. These oil/water
separators receive wastewater from various turbine processes, such as miscellaneous
piping leaks, wash down water and stormwater runoff. This wastewater may contain
small amounts of propylene glycol, lube oil and/or fuel oil as a result of piping leaks or
false starts from the turbine. The Chemicals on Site list shows additional chemicals
presently being used at the station and which may be present in the wastewater.
Generically, these chemicals may be classified as:

Lincoln Combustion Turbine, Lincoln County
NPDES Permit No.NC0080781
Page 5 of 9
• Corrosion inhibitors
• Housekeeping chemicals
• Surfactants and defoamers
• Maintenance chemicals and degreasers
• Water treatment chemicals.
The turbine sumps process approximately 90 to 4,200 Gallons Per Day (GPD) of
wastewater. The following are the waste streams that could be collected in the turbine
sumps which have oil/water separators, with the exception of the residual compressor
water wash, which by-passes the oil/water separators:
• Fuel oil from false starts
• Lube oil leaks
• Cooling water leaks
• Turbine deck wash water
• Fuel oil filter skid drains.
Fuel Oil From False Starts
A starting turbine may not get an ignition flame on the first attempt. As a result, the
engine has to be shut down and the combustion chamber fuel drained prior to a
system restart.
Lube Oil Leaks
Intermittent lube oil piping leaks may occur on each combustion turbine during
normal operation. When the combustion turbine decks are periodically hosed down
with water as part of the housekeeping practices, these trace amounts of oil are
flushed to the oil/water separator.
Cooling Water Leaks
Intermittent cooling water leaks may occur around the cooling water system
pressure fitting gaskets. This leakage amount is usually very small. These leaks
contain propylene glycol and a corrosion inhibitor.
Turbine Deck Wash Water
During normal operation, the combustion turbines or their decks are periodically
washed with water for housekeeping purposes. This volume is approximately 200 to
400 gallons.
Fuel Oil Filter Skid Drains
Fuel oil filter skids are located in the turbine yard separately from the combustion
turbines. There is a filter skid for each combustion turbine. Each skid area is
curbed and furnished with a yard drain. Rain water washes trace amounts of oil to
these drains which lead to the oil/water separator.

Lincoln Combustion Turbine, Lincoln County
NPDES Permit No.NC0080781
Page 6 of 9
Aeration tank wastewater
The aeration tank receives wastewater from the turbine yard sumps,
maintenance/warehouse sump and vehicle wash. The maintenance/warehouse sump
and the vehicle wash wastewater are received via an oil/water separator. In the
aeration tank the waste is mixed with activated sludge and aerated to reduce the total
organic carbon content.
Wastewater Treatment Basin Operation
Presently, the wastewater treatment basin is receiving wastewater streams from the
sources listed in the following sections of this Supplemental Information document:
Filtered Water System, Demineralized Water System, and Combustion Turbine Sumps.
Compressor Wash Water
The interior and blades of each turbine compressor is water washed normally once per
year. Approximately 3,000 to 3,500 gallons of water is used to perform this turbine
blade washing. This water drains directly to the turbine sumps. When this procedure is
being performed, the sump pumps are isolated and the sump acts as a collection point
for this wastewater. The wash water is pumped and hauled to a permitted disposal
facility.
Stormwater (sw)
SW runoff is diverted into six different drainage systems. SW systems are as follows:
SW 001
• Transformer skid oil/water separator
• Runoff from transformer skids
• Drains to the raw water storage pond, which over flows to wetlands then to Killian
Creek
SW 002
• North side runoff(Combustion Turbine Units 1 - 8 )
• Drains to the raw water storage pond, which over flows to wetlands then to Killian
Creek
SW 003
• Warehouse receiving area (small area)
• Drains to open area at East end of site
SW 004
• East side runoff
• Drains to wetlands then to Killian Creek
SW 005
• South side runoff(Combustion Turbine Units 9 - 16)
• Drains to wetlands then to Killian Creek

Lincoln Combustion Turbine, Lincoln County
NPDES Permit No.NC0080781
Page 7 of 9
SW 006
• Oil spill containment basin oil/water separator
• Used oil storage tank skid runoff
• Fuel oil unloading pad runoff
• Oil spill containment basin runoff
• Drains to wetlands then to Killian Creek.
Various herbicides and pesticides are applied on the site by a vendor. These
applications are applied in compliance with manufacturers' guidelines by licensed
applicators.
Drinking Water
Drinking water is supplied to the site from two wells. The site is not on the state drinking
water database because it does not meet the minimum personnel requirements.
Sanitary System
Sanitary wastes from the plant are treated by a 2,000 gallon septic tank. Sanitary
effluent is pumped by a lift station from the discharge chamber of the septic tanks to a
leachate field for final treatment. Based on annual data, the average daily flow to the
leachate field has been approximately 750 gallons per day. The sanitary system is
permitted by Lincoln County.
Spill Prevention
The LCT has two 5.5 million gallon above ground fuel oil storage tanks. Each above
ground oil tank at LCT was designed with secondary containment which is capable of
containing the entire contents of both tanks. This station has both an SPCC (Spill
Prevention, Control, and Countermeasures) plan as well as a FRP (Facility Response
Plan) as specified in Federal regulations 40 CFR 112. Detailed listings of oil sources at
this station are kept current in both the SPCC and FRP plans.

Permit NO0080781
A. (2.) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Cenodapbnia dubia at an effluent concentration of 23%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North
Carolina Ceriodapbnia 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 once during each calendar quarter. 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: NC DENR/DWQ/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.

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.

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. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.

Subject: NPDES Permit Renewal, NC#0080781
Lincoln Combustion Turbine, Lincoln County
Dear Mr. Goodrich:
The subject NPDES permit is scheduled to expire on February 28, 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
• Site maps
• Supplemental Information to the NPDES Application
• The Balanced Indigenous Population (BIP) Report.
Based on historical monitoring data, a monitoring reduction is requested for oil & grease from
quarterly to semi-annual. With the exception of one sample being 5 mg/I, the remaining
analytical results over the last two years have all been below detection.
Please note that in April 2004 the dechlorination system was put into service for outfall 001, per
Authorization to Construct approval number 080781 DC. Therefore, the Form 2C only includes
monitoring data for total residual chlorine after the dechlorination system was put into service.

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

General Site Information
The Lincoln Combustion Turbine (LCT) site consists of sixteen combustion turbine
generator units that supply 74 Megawatts per unit for a total of 1,184 Megawatts. The
Lincoln facility serves as a source of power during peak demand periods, and also
during times when energy from other sources may be unavailable. The greatest
electrical demand is usually in the summer and winter months. Each combustion
turbine can be operated independently and for extended periods of time, if necessary.
Combustion turbines burn #2 low-sulfur oil or natural gas to heat compressed air, which
expands and drives a turbine-generator to produce electricity. Construction of the LCT
units was completed in March of 1996.
On page 9 is a line drawing showing the water flow through LCT, indicating the source
of intake water, operations contributing to the effluent, and the wastewater treatment
provided. The estimated flows on the line drawing are representative of present station
operation. The following is a brief narrative description of sources contributing to the
wastewater effluent of outfall 001.
Intake
Raw water is withdrawn from Killian Creek and stored in the 50 million gallon Raw
Water Storage Pond. The pond is equipped with an overflow pipe to wetlands, which
flows into Killian Creek. The raw water intake screens are sparged with air periodically
to remove trapped creek debris. This debris is flushed back into the creek.
From this pond, raw water is processed by the filtered water and demineralized water
treatment systems in order to make pure service water for combustion turbine
operations and plant processes. The wastewater and chemicals generated by these
processes are discharged to the wastewater treatment system at the LCT site.
Outfall 001 - System Description
Outfall 001 discharges treated wastewater from the Wastewater Treatment (WT)
system through a flume to Killian Creek below the LCT site. The WT system basin
consists of two parallel concrete lined treatment cells (250,000 gallons each). The
treatment basin provides a common mixing point for all site wastewater. Discharge
from the basin is on a batch basis.
The wastewater treatment system provides settling, neutralization and dechlorination
prior to discharge. This basin processes wastewater flows from the water treatment
system and an aeration tank, which collects wastewater from four turbine yard sumps,
maintenance/warehouse sump and the vehicle wash. The total combined effluent from
these sources is approximately 0.10 million gallons per day (MGD). Wastewater from
the WT system is discharged to Killian Creek at Outfall 001.

Filtered Water System
Flow from the Raw Water Storage Pond is directed to the filtered water system where it
is treated for process use. The filtered water treatment system at LCT consists of a
clarifier, three gravity sand filters and a clear well. Wastewater and raw water solids
from the filtered water system are drained to the wastewater treatment basin, which
provides settling treatment. Solids are periodically removed from the wastewater
treatment ponds and properly disposed in accordance with G.S. 143-215.1 and in a
manner approved by the North Carolina Division of Environmental Management.
Clarifier
The clarifier utilizes typical water treatment chemicals such as cationic
polyelectrolyte, clay, and gaseous chlorine for the primary treatment of raw water.
The sedimentation wastes collected in the clarifier consists of solids that were
suspended in the service water. -
Just prior to the flash floc tank, gaseous chlorine is injected into the raw water. The
cationic polyelectrolyte is added from a unit called a "Poly Flow". This unit receives
dilution water from a filtered water compression skid and injects the polyelectrolyte
into the flash floc tank. Also, the clay receives dilution water from the filtered water
compression skid and the clay slurry is pumped into the flash floc tank.
Approximately 110 gallons per year of polyelectrolyte may be used. The average
volume of water required for desludging the clarifier is between 10,000 - 20,000
gallons per day. Typically, these sedimentation wastes (which consist of mud, silt,
clay and flocculent precipitate) along with diluted water treatment chemicals and by-
products, gravity flow from the bottom of the clarifier and are collected in the
wastewater treatment basin.
Gravity Filters
There are three gravity sand filters composed of anthracite (coal) and sand,
downstream of the clarifier in the water treatment process. Normally, each of these
filters is backwashed two to five times each day during peak operation. Each
backwash uses about 10,000 gallons of water. On the average, 90,000 gallons of
backwash water is produced daily from filter backwashes.
This wastewater drains to a cement trench that discharges to the wastewater
treatment basins. The sand filter is changed on an as needed basis. The filtered
water is stored in one of two 400,000 gallon filtered water tanks (A and B). Of this
total volume of water, 300,000 gallons are designated for fire protection usage.
Demineralized Water System
The Demineralized Water System provides high purity water which is injected into the
combustion turbines for nitrous oxide (NOx) control. The demin water is also used for
miscellaneous plant usage such as housekeeping, turbine deck wash water and cooling
water.

Activated Carbon Filters
The Demineralized Water System includes three, 235 ft3 carbon filters. These filters
are typically backwashed weekly. The amount of water required to backwash one of
these filters is approximately 10,000 gallons of water per backwash. Backwashes
may occur daily or weekly, depending on station operation. The carbon is
replenished as needed and the spent carbon is routed to the wastewater treatment
basin.
Demineralizers
There are three trains of resin bed regenerative demineralizers. Each train consists
of one anion resin bed and one cation resin bed. Normally, one to three trains of
demineralizers are in operation. The demineralized water produced is stored in two
demineralized water storage tanks (A and B) which have a capacity of 1.4 million
gallons each.
Regeneration of one anion/cation demineralizer train may occur as often as once
per day. A typical regeneration of one train takes approximately 50,000 gallons of
water. The amounts of required acid and caustic will vary as dictated by operational
requirements.
Wastewater from these regenerations is discharged to a 150,000 gallon
neutralization tank. The wastewater is neutralized prior to discharge to the
wastewater treatment basin. The acid and caustic used in the neutralization
process are stored in day tanks. The acid day tank holds 380 gallons and the
caustic day tank holds 730 gallons. In the event of a leak from the day tanks, the
acid or caustic would be neutralized and drained to the wastewater treatment
basins. The capacities of the bulk sulfuric acid and the sodium hydroxide tanks are
4,000 and 4,500 gallons respectively.
Combustion Turbine Sumps
The four turbine sumps are concrete structures which have two pumps per sump.
These pumps are operated on an alternating basis. After a preselected time period, the
controls are automatically cycled so the pump operation is swapped.
The turbine sumps collect wastewater from four oil/water separators. These oil/water
separators receive wastewater from various turbine processes, such as miscellaneous
piping leaks, wash down water and stormwater runoff. This wastewater may contain
small amounts of propylene glycol, lube oil and/or fuel oil as a result of piping leaks or
false starts from the turbine. The Chemicals on Site list (page 7), identifies additional
chemicals presently being used at the station and which may be present in the
wastewater. Generically, these chemicals maybe classified as:
• Corrosion inhibitors
• Housekeeping chemicals
• Surfactants and defoamers
• Maintenance chemicals and degreasers
• Water treatment chemicals.

The turbine sumps process approximately 90 GPD to 4,200 GPD of wastewater. The
following are the waste streams that could be collected in the turbine sumps which have
oil/water separators, with the exception of the residual compressor water wash which
by-passes the oil/water separators:
• Fuel oil from false starts
• Lube oil leaks
• Cooling water leaks
• Turbine deck wash water
• Fuel oil filter skid drains. -
Fuel Oil From False Starts
A starting turbine may not get an ignition flame on the first attempt. As a result, the
engine has to be shut down and the combustion chamber fuel drained prior to a
system restart.
Lube Oil Leaks
Intermittent lube oil piping leaks may occur on each combustion turbine during
normal operation. When the combustion turbine decks are periodically hosed down
with water as part of the housekeeping practices, these trace amounts of oil are
flushed to the oil/water separator.
Cooling Water Leaks
Intermittent cooling water leaks may occur around the cooling water system
pressure fitting gaskets. This amount is usually very small. These leaks contain
propylene glycol and a corrosion inhibitor.
Turbine Deck Wash Water
During normal operation, the combustion turbines or their decks are periodically
washed with water for housekeeping purposes. This volume is approximately 200 to
400 gallons.
Fuel Oil Filter Skid Drains
Fuel oil filter skids are located in the turbine yard separately from the combustion
turbines. There is a filter skid for each combustion turbine. Each skid area is
curbed and furnished with a yard drain. Rain water washes trace amounts of oil to
these drains which lead to the oil/water separator. •
Aeration tank wastewater
The aeration tank receives wastewater from the turbine yard sumps, service building
sump, maintenance/warehouse sump and vehicle wash. The maintenance/warehouse
sump and the vehicle wash are received via an oil/water separator. In the aeration tank
the waste is mixed with activated sludge and aerated to reduce the total organic carbon
content. -
Compressor Wash Water
The interior and blades of each turbine compressor is water washed normally once per
year. Approximately 3,000 to 3,500 gallons of water is used to perform this turbine
August 2004

blade washing. This water drains directly to the turbine sumps. When this procedure is
being performed, the sump pumps are isolated and the sump acts as a collection point
for this wastewater. The wash water is pumped and hauled to a permitted wastewater
treatment facility. At present this wastewater treatment facility is located at McGuire
Nuclear Station.
Stormwater (SW)
SW runoff is diverted into six different drainage systems. SW systems are as follows:
SW 001
• Transformer skid oil/water separator
• Runoff from transformer skids
• Drains to the raw water storage pond, which over flows to wetlands then to Killian
Creek
•
SW 002
• North side runoff(Combustion Turbine Units 1 - 8 )
• Drains to the raw water storage pond, which over flows to wetlands then to Killian
Creek
SW 003
• Warehouse receiving area (small area)
• Drains to open area at East end of site
SW 004
• East side runoff
• Drains to wetlands then to Killian Creek
SW 005
• South side runoff(Combustion Turbine Units 9 - 16)
• Drains to wetlands then to Killian Creek
SW 006
• Oil spill containment basin oil/water separator
• Used oil storage tank skid runoff
• Fuel oil unloading pad runoff
• Oil spill containment basin runoff
• Drains to wetlands then to Killian Creek.
Various herbicides and pesticides are applied on the site by a vendor. These
applications are applied in compliance with manufacturers' guidelines by licensed
applicators.
Drinking Water
Drinking water is supplied to the site from two wells. The site is not on the State's
drinking water database because it does not meet the minimum personnel
requirements.

Sanitary System
Sanitary wastes from the plant are treated by a 2,000 gallon septic tank. Sanitary
effluent is pumped by a lift station from the discharge chamber of the septic tanks to a
leachate field for final treatment. Based on annual data, the average daily flow to the
leachate field has been approximately 750 gallons per day. The sanitary system is
permitted by Lincoln County.
Spill Prevention
The LCT has two 5.5 million gallon above ground fuel oil storage tanks.- Each above
ground oil tank at LCT was designed with secondary containment which is capable of
containing the entire contents of both tanks. This station has both an SPCC (Spill
Prevention, Control, and Countermeasures) plan as well as a FRP (Facility Response
Plan) as specified in Federal regulations 40 CFR 112. Detailed listings of oil sources at
this station are kept current in both the SPCC and FRP plans.

EXECUTIVE SUMMARY
• Per agreement with the North Carolina Department of Environment and Natural
Resources (NCDENR), annual monitoring of macroinvertebrates and fish at selected
locations in Anderson, Killian, and Forney Creeks of the Catawba River basin has
continued since the initial request to construct Lincoln Combustion Turbine Station
(LCTS) in 1990. The objective of this on-going monitoring program is to provide
data to assess balanced and indigenous populations with respect to operation of
LCTS and evaluate renewal of the Station NPDES permit NC0080781.
• Killian Creek flows were substantially impacted by the mid-1998 through 2002
regional drought, culminating in severe flow reductions in summer and early fall
2002. Median monthly flows for the period June through September 2002 were less
than the 7Q10 flow for the monitoring site. LCTS water withdrawals from Killian
Creek occurred on 113 days during 2000 — 2003, or on 7.9 % of the available days.
The maximum daily withdrawal rate monitored and reported to NCDENR was 4.39
cfs (1971 gpm), occurring over a six-hour period on December 25, 2000. The volume
of water withdrawn by LCTS remained well within the limitations of the agreement
with NCDENR.
• The discharge of wastewater by LCTS occurred on 118 of 1,429 days (< 8.3 % of
days) during 2000 — 2003. Wastewater discharges by volume averaged 5.6 % of the
average daily stream flow for Killian Creek during 2000 — 2003. Annual average
mixing ratios for LCTS wastewater discharges into the receiving stream over this
period were: 2.9 % (2000); 2.3% (2001); 23.4% (2002); and 0.8% (2003).
• The bioclassifications assigned based on analysis of the macroinvertebrates collected
in Anderson, Forney, and Killian Creeks ranged from "Poor" to "Good-Fair". In
comparison to the other sampling sites, the Forney Creek sampling location had the
lowest bioclassification each year, with steadily decreasing bioclassifications from
2000 through 2003. Typically, the control location had a bioclassification similar to
the first Killian Creek location and results indicate a decrease in bioclassification at
the Forney Creek location and then a gradual increase _in bioclassification
downstream. Results from 2000 through 2003 show lower bioclassifications than
data observed from 1996 through 1999. The lower bioclassifcations may be the result
of significant fluctuations in stream flow and the possible influence of Forney Creek.

• The fish community in Anderson, Forney, and Killian Creeks has been monitored
since 1989 and is typical for Piedmont streams in Lincoln County, North Carolina.
The LCTS fish community represents nine families and encompasses a range of
trophic groups including herbivores, insectivores, omnivores, and piscivores. The
fish species present are consistent with those documented by other sources and
include no threatened or endangered species. -
• Streams in the vicinity of LCTS support a relatively low percentage of pollution
tolerant individuals, several pollution intolerant species, and a desirable distribution
of species from various trophic guilds. The fish community in Anderson and Killian
Creeks has exhibited no visible impact from LCTS on the number of fish species or
fish biomass during construction and numerous years of operation. Most of the fish
community changes that have been noted are probably attributable to WWTP
operations and/or development related disturbances in the Forney Creek watershed.
Because the fish community in Anderson, Forney, and Killian Creeks is characterized
by species diversity, low percentages of pollution tolerant individuals, trophic level
diversity, and sustainability through time, it is concluded that there is a balanced,
indigenous fish community in the creeks adjacent to LCTS.

CHAPTER 1
INTRODUCTION
Per agreement with the North Carolina Department of Environment and Natural Resources
(NCDENR), annual monitoring of macroinvertebrates and fish at selected locations in
Anderson, Killian, and Forney Creeks of the Catawba River basin has continued since the
initial request to construct in Lincoln Combustion Turbine Station(LCTS) in 1990(Table 1-1
and Figure 1-1). The objective of this on-going monitoring program is to provide data to
assess balanced and indigenous populations with respect to operation of LCTS and evaluate
renewal of the station National Pollutant Discharge Elimination System (NPDES) permit
NC0080781.
The Lincoln Combustion Turbine Station is located approximately 18 mi northwest of
Charlotte in Lincoln County, North Carolina. Stream stretches of Anderson and Killian
Creeks border the 711-acre LCTS site in the Catawba River basin (Hydrologic Unit
03050102). The sixteen independent simple cycle combustion turbine units have a combined
nameplate capacity of 1152 MW. Each unit is rated at 72 MW. The water intake and
discharge structures of LCTS are located on Killian Creek. Withdrawal and discharge of
water occurs intermittently corresponding to operation cycles of LCTS to help meet customer
electricity needs during peak demand times.
Reviews of past studies by regulators have determined that the intake and discharge of water
by LCTS assures the protection and propagation of balanced, indigenous populations in the
adjacent creeks of the Catawba River basin (Duke Power 1990 and 2001). This report
presents data collected from 2000 through 2003 (2000 Fish data was reported in the previous
report). Also these data were compared with other past and present on-going environmental
monitoring programs conducted in this watershed.

CHAPTER 2
STATION OPERATION
BACKGROUND INFORMATION
The study area comprises a portion of Catawba River Sub-basin 33, in the southeastern
corner of Lincoln County, NC. Anderson and Forney Creeks are first-order streams that
ultimately combine with Killian Creek above and below, respectively, the Lincoln
Combustion Turbine Station (LCTS) site. Killian Creek in turn is a tributary of Dutchmans
Creek, which flows into the Catawba River at upper Lake Wylie in Mt Holly, NC. The
Lincoln County portion of the watershed is primarily forested, although suburban
development near the Highway 73 corridor, which transects the streams upstream of LCTS,
has accelerated in the last several years. Streams in this area are typically low-gradient with
steep banks, and sandy substrates are common. LCTS is the only NPDES-permitted facility
on Killian Creek. Permitted discharges to Forney Creek include the Forney Creek
Wastewater Treatment Plant, and a granite quarry operated by B.V. Hedrick-Lowesville.
Water quality of streams in this area is typified by low nutrient concentrations, but highly
variable turbidity and concentrations of solids, depending on stream stage and recent
precipitation history. Total alkalinity(23 —45 mg/L as CaCO3) and pH (6.6 — 7.8 SU) show
relatively little temporal variability. Specific conductance has varied somewhat from
sampling to sampling, with historical values in the range of 67— 126 µS/cm reported by Duke
Power (1990), and more recently, values up to 131 µS/cm reported by NCDENR (2003).
Water quality monitoring prior to construction of LCTS showed turbidity and concentrations
of iron and copper occasionally exceeding state water quality standards or action levels in
upper Killian Creek(Duke Power 1990).
Water withdrawal from, and discharge to, Killian Creek by LCTS occurs intermittently based
on customer electrical demand for station operation. Per agreement with NCDENR, water
can only be withdrawn from Killian Creek when flows are above 7Q10, estimated as 2.28 cfs
(Duke Power 1990). Also, no more than 25% of the Killian Creek flow can be withdrawn at
any time, with maximum withdrawal capped at 10 cfs (6.46 mgd).
2-1

The flow of Killian Creek at LCTS is monitored at a United States Geological Survey
(USGS) gaging station (USGS 0214269560, Killian Creek near Mariposa, NC). The gage
was installed in 1990 on the opposite bank of the creek from the LCTS intake structure,
approximately 1,000 ft upstream from the confluence with Forney Creek (Figure 1-1). The
period of record for the gage spans all operational years for LCTS. Because this gage was
designed to assist in the quantification of critical low flow conditions, data from periodic
high flow events exceeding the gage height(643.08 ft msl) are not available for this site.
The LCTS intake structure consists of a concrete chute and an adjacent sump in which pumps
are mounted. The threshold elevation between the chute and the sump prevents Killian Creek
water from entering the sump during periods of critical low stream flow. Following
operation of LCTS units, water withdrawn at the intake structure is pumped to the raw water
storage pond, as needed to replenish the water supply for future operation. The capacity of
the raw water storage pond is approximately 153 acre-ft. An annual report detailing the date
and volume of water withdrawn by LCTS and respective Killian Creek flow is provided to
NCDENR.
The LCTS wastewater treatment system receives discharge from station sumps and a clarifier,
and neutralized effluent from a demineralizer regeneration waste tank. Effluent is collected
in the inlet distribution channel and routed to one of two basins. Each basin provides an
estimated 24 hours of retention for settling of suspended solids and removal of any entrained
oil. The pH of the effluent can be adjusted prior to discharge by the addition of acid or
caustic. Operation of the waste water recycle pump ensures thorough mixing prior to
discharge. After pH adjustment, the effluent is discharged to Killian Creek downstream of
the LCTS intake structure. The effluent is sampled and results of analyses are submitted
monthly to NCDENR, as required by the NPDES permit of LCTS.
OPERATION DATA
Killian Creek flows were substantially impacted by the mid-1998 through 2002 regional
drought, culminating in severe flow reductions in summer and early fall 2002 (USGS 2004;
Figures 2-1 and 2-2). Median monthly flows for the period June through September 2002
were less than the 7Q10 flow for the monitoring site. Results of monitoring by NCDENR in
2002 implicated low stream flows in this sub-basin as a cause of declines in fish species
2-2

diversity, as well as increased abundance of pollution tolerant macroinvertebrate taxa in
Killian Creek. Stream width for Killian Creek at the SR1157 site (Location D) was reduced
from a typical 7 to 10 meters, to 4 meters at the time of sampling by NCDENR (NCDENR
2003).
LCTS water withdrawals from Killian Creek occurred on 113 days during 2000—2003, or on
7.9 % of the available days. The maximum daily withdrawal rate monitored and reported to
NCDENR was 4.39 cfs (1971 gpm), occurring over a six-hour period on December 25, 2000.
The volume of water withdrawn by LCTS remained well within the limitations of the
agreement with NCDENR.
The discharge of wastewater by LCTS occurred on 118 of 1,429 days (< 8.3 % of days)
during 2000 — 2003. Wastewater discharges by volume averaged 5.6 % of the average daily
stream flow for Killian Creek during 2000 — 2003. Annual average mixing ratios for LCTS
wastewater discharges into the receiving stream over this period were: 2.9 % (2000); 2.3%
(2001); 23.4% (2002); and 0.8% (2003). At the peak of the drought, in the summer of 2002,
Killian Creek stream flow fell substantially below the 7Q10, and measured flow approached
zero for an extended period in August 2002. Wastewater discharged from LCTS briefly
dominated the flow of Killian Creek, particularly for two dates; August 1 and August 9, 2002
(Figure 2-3). Following appreciable rainfall and restoration of groundwater elevations in the
latter part of 2002 and 2003, stream flow and wastewater mixing ratios returned to more
typical levels.

CHAPTER 3
MACROINVERTEBRATES
METHODS AND MATERIALS
The benthic macroinvertebrate monitoring program continued near the Lincoln Combustion
Turbine Station (LCTS) from 2000 through 2003. Annual bioassessment sampling was
conducted in late July or early August of each year to assess potential effects of the operation
of LCTS on macroinvertebrate communities in Killian Creek. The standard qualitative
method as outlined in the North Carolina-Department of Environment and Natural Resources
(NCDENR) Standard Operating Procedures (SOP) was used in collecting samples from
Locations A, B, C, D, and G (Table 1-1 and Figure 1-1). This method involves the use of a
variety of nets to sample the major habitats available at a particular location. Organisms are
sorted from debris in the field, and identified to the lowest practicable taxon in the laboratory.
Analysis results in a bioclassification for each location which gives equal consideration to the
number of Ephemeroptera, Plecoptera and Trichoptera (EPT) taxa present and the biotic
index value. The biotic index value is calculated for all taxa collected from the same
location. Biologists with NCDENR have assigned biotic index values for benthic taxa based
on their relative tolerance to environmental perturbations. A score is assigned to the EPT
value and to the mean biotic index. The mean of these two scores is used to assign one of
five bioclassifications, from Poor to Excellent (NCDENR 2003). The assessment of the
balanced and indigenous nature of the benthic community is determined by comparing EPT
abundance and biotic index values at locations upstream of, adjacent to, and downstream of
LCTS.
RESULTS AND DISCUSSION
Bioclassi fication
The bioclassifications assigned based on analysis of the macroinvertebrates collected in 2000
through 2003 at LCTS Locations A, B, C, D, and G ranged from "Poor" to "Good-Fair"
(Figure 3-1). Typically, Location A had a bioclassification similar to Location .B,_then a
gradual decrease in bioclassification was observed at Location C, and Location D typically
had the highest bioclassification. In comparison to the other sampling sites, the Forney Creek
sampling location (Location G) had the lowest bioclassification each year, with steadily
3-1

decreasing bioclassifications from 2000 through 2003. Factors influencing the low
bioclassification at Location G may have also impacted the bioclassification at Location C,
the immediate downstream location. Results at all locations from 2000 through 2003 show
lower bioclassifications than data observed from 1996 through 1999.
Total Taxa and EPT Taxa
Similar increases and decreases were observed in the number of total taxa and number of
EPT taxa collected (Figures 3-2 and 3-3 and Appendix Tables A-1 through A-5). The total
taxa collected at Location A were typically greater than or equal to those collected at
Location B except in 2000 when Location B had more total taxa present than Location A.
Total taxa collected at Location C were generally equal to Location B except in 2000 when
Location B was greater. Total taxa at Location D generally increased relative to upstream
locations. Total taxa observed were generally lowest at Location G every summer from 2000
through 2003.
There was a general trend observed in EPT taxa with higher numbers at Location A, lower
numbers at Locations B and C, and then an increase at Location D. The exception occurred
in 2000 when EPT taxa at Location B exceeded the number observed at Location A. The
Forney Creek location (Location G) exhibited the lowest numbers of EPT taxa during all
years from 2000 through 2003.
There were some occasions when locations had the same taxa present every year. These taxa
are highlighted in Appendix A, Tables A-1 through A-5. The most commonly found taxa
throughout the 2000 through 2003 study included: Macronychus glabratus, Stenonema
modestum, Cheumatopsyche spp., Gomphus spp., and Boyeria vinosa.
Water Quality
Dissolved oxygen, conductivity, and temperature were measured for the first time in 2003
and will continue to be monitored during annual macroinvertebrate sampling. Dissolved
oxygen ranged from 8.0 mg/L to 9.2 mg/L, conductivity measurements ranged from 69.9
µS/cm to 188.5 µS/cm, and the water temperature ranged from 67.6°F (19.8°C) to 68.7°F
(20.4°C) (Table 3-1). There was a general increase in conductivity with downstream
direction among the sample locations. Forney Creek (Location G) appeared to be a source of
3-2

substantially greater conductivity water, most likely attributable to upstream wastewater
imputs.
Flow
Based on comparisons of annual macroinvertebrate collections from 2000 through 2003 with
previous annual collections from Locations A, B, C, D, and G, stream flow appeared to be a
major influence on macroinvertebrate communities (Figure 3-4). Reduced flow associated
with drought conditions that existed during the summers of 2000 through 2002 created poorer
sampling habitat than that sampled in pre-drought years (Table 3-2). Leaf-packs, root
masses, and riffle areas may have existed during the time of sample collection but it is
important to note that water levels were so low during 2000 through 2002 that normally
submerged habitat may have been exposed for an extended period of time. In contrast, water
levels were high in 2003, creating flood conditions which scoured sampling habitat and
created erosion along creek banks.
Forney Creek
The influence of Forney Creek (Location G) on the Killian Creek macroinvertebrate
communities is a distinct possibility leading to the lower taxa richness and EPT taxa at
Location C. During 2000 through 2002 Forney Creek had a gray color in comparison to
Killian Creek. In 2003 the water color was even more dissimilar. There appeared to be fine
gray silt (i.e., cement fines left in the stream from the observed quarry incident in 1997)
suspended in the water and a notable amount of silt was still observed in the substrate.
CONCLUSION
Macroinvertebrate monitoring results from LCTS 2000 through 2003 suggest that Forney
Creek and fluctuations in stream flow may be influencing Killian Creek macroinvertebrate
communities. A consistent pattern exists in bioclassifications observed during the 2000
through 2003 study period. In every instance both the control site (Location A) and the first
LCTS site on Killian Creek (Location B) have comparable bioclassifications and both
locations have higher bioclassifications than the Forney Creek location (Location G). The
sampling location below the confluence of Forney Creek with Killian Creek (Location C)
tends to have a bioclassification higher than Location G but not as high as Locations A and B,
which indicates Forney Creek may have an impact on Killian Creek. However, the Killian
3-3

Creek benthic communities appear to recover at some point upstream of the sampling
location below LCTS (Location D). In comparison to all the other sampling sites, Location D
had the highest bioclassification during three of four sampling periods.

Dear Mr. Ruhe:
The Division received your request to modify the subject permit on December 21, 2001. After a review
of the permit file,it was decided that no modification of the permit was necessary. However, this letter is
designed to clarify the points you raised.
The Division's responses to your points are as follows:
> Quarterly samples for BOD5,Total Suspended Solids,NH3 as N and Oil& Grease may be collected
•
in the same months as those specified for your toxicity samples (March,June,September and
December). It is not required that you monitor during those months only,but merely once each
calendar quarter (see below). The monitoring schedule you propose is acceptable to the Division.
> Calendar quarters are defined at Part II.A. 6. g. of your permit. This definition of calendar quarters
is standard for all NPDES permits, and does not require modification. Your proposed monitoring
schedule does not conflict with the existing definition of calendar quarters.
> Your proposal for DMR submittal during months with no discharge is acceptable. This procedure is
already in effect for toxicity test results (see Part I. A. (2.)).
If you have any questions concerning this permit modification,please contact Charles Weaver of the
NPDES Unit at [phone], extension 511.

are to be monitored in March, June, September, and December.
2. For quarterly monitoring, quarters are defined as March — May, June—August,
September— November, and December— February.
3. If the waste treatment system does not have a discharge for the month or a particular
quarter; then no monitoring is required. Under those conditions the Discharge

Dear Mr. Ruhe:
Our records indicate that NPDES Permit No.NC0080781 was issued on October 5, 2001 for
the discharge of wastewater to the surface waters of the State from your facility. The purpose of this
letter is to advise you of the importance of the Permit and the liabilities in the event of failure to
comply with the terms and conditions of the Permit. If you have not already done so, it is suggested
that you thoroughly read the Permit. Of particular importance is Page 4.
Page 4 sets forth the effluent limitations and monitoring requirements for your discharge.
Your discharge must not exceed any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types and sampling locations. Upon
commencement of your discharge (or operation), you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or approved by this Agency. If you
have not received these forms, they should be arriving shortly. If you fail to receive the forms, please
contact this Office as quickly as possible. I have enclosed a sample of the "Effluent" reporting form
(DWQ Form MR-1), plus instructions for completing the form. It is imperative that a applicable
parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required
for your facility. You will soon be receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent enforcement action or possible revocation of
your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or"the Division" Means the Division of Water Quality,Department of Environment and Natural
Resources.
3. EMC Used herein means the North Carolina Environmental Management Commission.
4. Act or"the Act" The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,
33 USC 1251,et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during a calendar month on which daily discharges are sampled and measured,divided by the number of daily
discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by
adding the weights of the pollutant found each day of the month and then dividing this sum by the number
of days the tests were reported. The limitation is identified as"Monthly Average"in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is,therefore,an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average"in Part I of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as "Daily Maximum,"in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are sampled and measured,divided by the number of daily
discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding
the weights of pollutants found each day of the year and then dividing this sum by the number of days the
tests were reported. This limitation is defined as "Annual Average"in Part I of the permit.
6. Concentration Measurement
a. The "average monthly concentration,"other than for fecal coliforrn bacteria,is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured during such
month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation
is identified as "Monthly Average" under"Other Limits" in Part I of the permit.

Part II
Pr Page 2 of 11
6.b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily
discharges are sampled and measured divided by the number of daily discharges sampled and/or measured
during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal
to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted
by flow value) of all the samples collected during that calendar day. The average weekly count for fecal
coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This
limitation is identified as "Weekly Average" under"Other Limits"in Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If
only one sample is taken during any calendar day the concentration of pollutant calculated from it is the
"Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part I of the
permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled
and measured divided by the number of daily discharges sampled and/or measured during such year
(arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average yearly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as"Annual Average" under"Other Limits"in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved
oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one
dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average
concentration" for the discharge. It is identified as"daily average"in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is
identified as "Quarterly Average Limitation"in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods:January through March,April through
June,July through September,and October through December.
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is
determined as the arithmetic mean of the total daily flows recorded during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the
sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually
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.
8. Types of Samples
a. Composite Sample:A composite sample shall consist of:
(1) 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

Part I
Page 3 of 11
8. a. (2) 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 present
gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system,or
(3) a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no greater than
once per hour, and the time interval between effluent grab samples shall be no greater 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 time intervals evenly spaced over the 24-hour period which are
equal in number of hours to the detention time of the system in number of days. However, in no case
may the time interval between effluent grab samples be greater than six (6) hours nor the number of
samples less than four(4) during a 24-hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes;
the grab sample can be taken manually. Grab samples must be representative of the discharge or the
receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided
by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual
values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog
of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric
mean,values of zero (0) shall be considered to be one(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its
respective flow divided by the summation of the respective flows.
10. Calendar Day: A calendar day is defined as 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.
11. Hazardous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant: A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean
Water Act.
SECTION B. GENERAL CONDITIONS
I. Duty to Comply

It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means 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.
(2) "Severe property damage" means substantial physical damage to property, damage to the treatment
facilities which causes them to become inoperable,or substantial and permanent loss of natural resources
which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not
mean economic loss caused by delays in production.

Part II
Page 7 of 11
4.b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded,but
only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provisions of Paragraphs c.and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II,
E. 6.of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee
for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life,personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance;and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects,if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph
d. (1) of this section.
5. Upsets
a. Definition: "Upset" means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the reasonable
control of the permittee. An upset does not include noncompliance to the extent caused by operational
error,improperly designed treatment facilities,inadequate treatment facilities,lack of preventive maintenance,
or careless or improper operation.
b. Effect of an upset: An upset constitutes an affirmative defense to an action brought for noncompliance
with such technology based permit effluent limitations if the requirements of paragraph c. of this condition
are met. No determination made during administrative review of claims that noncompliance was caused by
upset,and before an action for noncompliance,is final administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset: A permittee who wishes to establish the
affirmative defense of upset shall demonstrate, through properly signed,contemporaneous operating logs,or
other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated;and
(3)The permittee submitted notice of the upset as required in Part II,E. 6. (b) (B) of this permit.
(4)The permittee complied with any remedial measures required under Part II,B.2.of this permit.
d. Burden of proof: In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.

Part II

6. Removed Substances
Solids, sludges, filter backwash,or other pollutants removed in the course of treatment or control of wastewaters
shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to prevent any pollutant
from such materials from entering waters of the State or navigable waters of the United States. The permittee
shall comply with all existing federal regulations governing the disposal of sewage sludge. Upon promulgation of
40 CFR Part 503, any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be
reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503.
The permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of Sewage
Sludge (when promulgated) within the time provided in the regulation, even if the permit is not modified to
incorporate the requirement. The permittee shall notify the Permit Issuing Authority of any significant change in
its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation, Title 15A,
North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the discharge of untreated or
inadequately treated wastes during electrical power failures either by means of alternate power sources, standby
generators or retention of inadequately treated effluent.
SECTION D. MONITORING AND RECORDS

Dear Mr. Ruhe:
The NPDES Unit received your permit renewal application on January 25, 2001. Thank you for submitting
this package.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff. That staff
member will contact you if further information is needed to complete the permit renewal. Please note that
the NPDES Unit has several vacant positions. This staff shortage has lasted for over a year and is delaying
all permit renewals. Our remaining permit writers are currently reviewing Authorizations to Construct,
speculative limit requests, major permit modifications and 201 plan updates ahead of permit renewals. This
is necessary due to a variety of factors, including mandatory deadlines in the statutes which govern our
program.
If this staff shortage delays reissuance of NC0080781 the existing requirements in your permit will remain
in effect until the permit is renewed (or the Division takes other action). We appreciate your patience and
understanding while we operate with a severely depleted staff. If you have any additional questions
concerning renewal of the subject permit, please contact me at(919) 733-5083,extension 520.

General Site Information
The Lincoln Combustion Turbine (LCT) site consists of sixteen combustion turbine
generator units that supply 74 Megawatts per unit for a total of 1 ,184 Megawatts.
The Lincoln facility serves as a primary source of power during peak demand
periods, and also during times when energy from other sources may be unavailable.
The greatest electrical demand is usually in the summer and winter months. Each
combustion turbine can be operated independently and for extended periods of
time, if necessary.
Combustion turbines burn #2 low-sulfur oil or natural gas to heat compressed air,
which expands and drives a turbine-generator to produce electricity. Construction
of the LCT units was completed in March of 1996.
On page 10 is a line drawing showing the water flow through LCT, indicating the
source of intake water, operations contributing to the effluent, and the wastewater
treatment provided. The estimated flows on the line drawing are representative of
present station operation. The following is a brief narrative description of sources
contributing to the wastewater effluent of outfall 001 .
Intake
Raw water is withdrawn from Killian Creek and stored in the 50 million gallon Raw
Water Storage Pond. The pond is equipped with an overflow pipe to wetlands,
which flows into Killian Creek. The raw water intake screens are sparged with air
periodically to remove trapped creek debris. This debris is flushed back into the
creek. Dredging of the intake is done periodically in accordance with the ACOE
404 permit (#199404202).
From this pond, raw water is processed by the filtered water and demineralized
water treatment systems in order to make pure service water for combustion
turbine operations and plant processes. The wastewater and chemicals generated
by these processes are discharged to the wastewater treatment system at the LCT
site.
Outfall 001 - System Description
Outfall 001 discharges treated wastewater from the Wastewater Treatment (WT)
system through a flume to Killian Creek below the LCT site. The WT system basin
consists of two parallel concrete lined treatment cells (250,000 gallons each). The
treatment basin provides a common mixing point for all site wastewater. Discharge
from the basin is on a batch basis and is neutralized as needed while discharging.
The wastewater treatment system provides settling and neutralization prior to
discharge. This basin processes wastewater flows from the water treatment
system and an aeration tank, which collects wastewater from four turbine yard
sumps, maintenance/warehouse sump and the vehicle wash. The total combined
effluent from these sources is approximately 0.30 million gallons per day (MGD).
Wastewater from the WT treatment system is discharged to Killian Creek at Outfall
001 .

Filtered Water System
Flow from the Raw Water Storage Pond is directed to the filtered water system
where it is treated for process use. The filtered water treatment system at LCT
consists of a clarifier, three gravity sand filters and a clear well. Wastewater and
raw water solids from the filtered water system are drained to the wastewater
treatment basin, which provides settling treatment. Solids are periodically removed
from the wastewater treatment ponds and properly disposed in accordance with
G.S. 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
Clarifier
The clarifier utilizes typical water treatment chemicals such as cationic
polyelectrolyte, clay, and gaseous chlorine for the primary treatment of raw
water. The sedimentation wastes collected in the clarifier consists of solids
that were suspended in the service water.
Just prior to the flash floc tank, gaseous chlorine is injected into the raw water.
The cationic polyelectrolyte is added from a unit called a "Poly Flow". This unit
receives dilution water from a filtered water compression skid and injects the
polyelectrolyte into the flash floc tank. Also, the clay receives dilution water
from the filtered water compression skid and the clay slurry is pumped into the
flash floc tank.
Approximately 110 gallons per year of polyelectrolyte may be used. The
average volume of water required for desludging the clarifier is between 10,000
- 20,000 gallons per day. Typically, these sedimentation wastes (which consist
of mud, silt, clay and flocculent precipitate) along with diluted water treatment
chemicals and by-products, gravity flow from the bottom of the clarifier and are
collected in the wastewater treatment basin.
Gravity Filters
There are three gravity sand filters composed of anthracite (coal) and sand,
downstream of the clarifier in the water treatment process. Normally, each of
these filters is backwashed two to five times each day during peak operation.
Each backwash uses about 10,000 gallons of water. On the average, 90,000
gallons of backwash water is produced daily from filter backwashes.
This wastewater drains to a cement trench that discharges to the wastewater
treatment basins. The sand filter is changed on an as needed basis. The filtered
water is stored in one of two 400,000 gallon filtered water tanks (A and B). Of
this total volume of water, 300,000 gallons are designated for fire protection
usage.

Demineralized Water System
The Demineralized Water System provides high purity water which is injected into
the combustion turbines for nitrous oxide (NOx) control. The demin water is also
used for miscellaneous plant usage such as housekeeping, turbine deck wash water
and cooling water makeup.
Activated Carbon Filters
The Demineralized Water System includes three, 235 ft3 carbon filters. These
filters are typically backwashed weekly. The amount of water required to
backwash one of these filters is approximately 10,000 gallons of water per
backwash. Backwashes may occur daily or weekly, depending on station
operation. The carbon is replenished as needed and the spent carbon is routed
to the wastewater treatment basin.
Demineralizers
There are three trains of resin bed regenerative demineralizers. Each train
consists of one anion resin bed and one cation resin bed. Normally, one to three
trains of demineralizers are in operation. The demineralized water produced is
stored in two demineralized water storage tanks (A and B) which have a
capacity of 1 .4 million gallons each.
Regeneration of one anion/cation demineralizer train may occur as often as once
per day. A typical regeneration of one train takes approximately 50,000 gallons
of water. The amounts of required acid and caustic will vary as dictated by
operational requirements.
Wastewater from these regenerations is discharged to a 150,000 gallon
neutralization tank. The wastewater is neutralized prior to discharge to the
wastewater treatment basin. The acid and caustic used in the neutralization
process are stored in day tanks. The acid day tank holds 380 gallons and the
caustic day tank holds 730 gallons. In the event of a leak from the day tanks,
the acid or caustic would be neutralized and drained to the wastewater
treatment basins. The capacities of the bulk sulfuric acid and the sodium
hydroxide tanks are 4,000 and 4,500 gallons respectively.
Combustion Turbine Sumps
The four turbine sumps are concrete structures which have two pumps per sump.
These pumps are operated on an alternating basis. After a preselected time period,
the controls are automatically cycled so the pump operation is swapped.
The turbine sumps collect wastewater from four oil/water separators. These
oil/water separators receive wastewater from various turbine processes, such as
miscellaneous piping leaks, wash down water and stormwater runoff. This
wastewater may contain small amounts of propylene glycol, lube oil and/or fuel oil
as a result of piping leaks or false starts from the turbine. The Chemicals on Site
list (page 8), lists additional chemicals presently being used at the station and
lanuary 01

which may be present in the wastewater. Generically, these chemicals may be
classified as:
• Corrosion inhibitors
• Housekeeping chemicals
• Surfactants and defoamers
• Maintenance chemicals and degreasers
• Water treatment chemicals.
The turbine sumps process approximately 90 GPD to 4,200 GPD of wastewater.
The following are the waste streams that could be collected in the turbine sumps
which have oil/water separators, with the exception of the residual compressor
water wash which by-passes the oil/water separators:
• Fuel oil from false starts
• Lube oil leaks
• Cooling water leaks
•Turbine deck wash water
• Fuel oil filter skid drains.
Fuel Oil From False Starts
A starting turbine may not get an ignition flame on the first attempt. As a
result, the engine has to be shut down and the combustion chamber fuel drained
prior to a system restart.
Lube Oil Leaks
Intermittent lube oil piping leaks may occur on each combustion turbine during
normal operation. When the combustion turbine decks are periodically hosed
down with water as part of the housekeeping practices, these trace amounts of
oil are flushed to the oil/water separator.
Cooling Water Leaks
Intermittent cooling water leaks may occur around the cooling water system
pressure fitting gaskets. This amount is usually very small. These leaks contain
propylene glycol and a corrosion inhibitor.
Turbine Deck Wash Water
During normal operation, the combustion turbines or their decks are periodically
washed with water for housekeeping purposes. This volume is approximately
200 to 400 gallons.
Fuel Oil Filter Skid Drains
Fuel oil filter skids are located in the turbine yard separately from the
combustion turbines. There is a filter skid for each combustion turbine. Each
skid area is curbed and furnished with a yard drain. Rain water washes trace
amounts of oil to these drains which lead to the oil/water separator.

Aeration tank wastewater
The aeration tank receives wastewater from the turbine yard sumps,
maintenance/warehouse sump and vehicle wash. The maintenance/warehouse
sump and the vehicle wash are received via an oil/water separator. In the aeration
tank the waste is mixed with activated sludge and aerated to reduce the total
organic carbon content.
•
Wastewater Treatment Basin Operation
Presently, the wastewater treatment basin is receiving wastewater streams from
those sources listed in the following sections of this Supplemental Information:
Filtered Water System, Demineralized Water System, and Combustion Turbine
Sumps.
Compressor Wash Water
The interior and blades of each turbine compressor is water washed normally once
per year. Approximately 3,000 to 3,500 gallons of water is used to perform this
turbine blade washing. This water drains directly to the turbine sumps. When this
procedure is being performed, the sump pumps are isolated and the sump acts as a
collection point for this wastewater. The wash water is pumped and hauled to a
permitted disposal facility.
Stormwater (SW)
SW runoff is diverted into six different drainage systems. SW systems are as
follows:
SW 001
• Transformer skid oil/water separator
• Runoff from transformer skids
• Drains to the raw water storage pond, which over flows to wetlands then to
Killian Creek
SW 002
• North side runoff (Combustion Turbine Units 1 - 8 )
• Drains to the raw water storage pond, which over flows to wetlands then to
Killian Creek
SW 003
• Warehouse receiving area (small area)
• Drains to open area at East end of site
SW 004
• East side runoff
• Drains to wetlands then to Killian Creek
SW 005
• South side runoff (Combustion Turbine Units 9 - 16)
• Drains to wetlands then to Killian Creek

SW 006
• Oil spill containment basin oil/water separator
• Used oil storage tank skid runoff
• Fuel oil unloading pad runoff
• Oil spill containment basin runoff
• Drains to wetlands then to Killian Creek.
Various herbicides and pesticides are applied on the site by a vendor. These
applications are applied in compliance with manufacturers' guidelines by licensed
applicators.
Drinking Water
Drinking water is supplied to the site from two wells. The site is not on the State's
drinking water database because it does not meet the minimum personnel
requirements.
Sanitary System
Sanitary wastes from the plant are treated by a 2,000 gallon septic tank. Sanitary
effluent is pumped by a lift station from the discharge chamber of the septic tanks
to a leachate field for final treatment. Based on annual data, the average daily flow
to the leachate field has been approximately 750 gallons per day. The sanitary
system is permitted by Lincoln County.
Spill Prevention
The LCT has two 5.5 million gallon above ground fuel oil storage tanks. Each
above ground oil tank at LCT was designed with secondary containment which is
capable of containing the entire contents of both tanks. This station has both an
SPCC (Spill Prevention, Control, and Countermeasures) plan as well as a FRP
(Facility Response Plan) as specified in Federal regulations 40 CFR 112. Detailed
listings of oil sources at this station are kept current in both the SPCC and FRP
plans.

• EXECUTIVE SUMMARY
• Per agreement with the North Carolina Department of Environment and Natural
Resources (NCDENR), annual monitoring of macroinvertebrates and fish at selected
locations in Anderson, Killian, and Forney Creeks of the Catawba River basin has
continued since the initial request to construct Lincoln Combustion Turbine Station
(LCTS) in 1990. The objective of this on-going monitoring program is to provide
data to assess balanced and indigenous populations with respect to operation of
LCTS and evaluate renewal of the Station NPDES permit NC0080781.
• From 1990 through 1999, the minimum monthly flow of Killian Creek occurred in 11
of 12 months in 1999 with the lowest flow of 3.77 cfs (2.44 mgd) in September 1999.
The volume of water withdrawn by LCTS was well within the limitations of the
agreement with NCDENR. In addition, the design of the LCTS intake structure
assured continuous stream flow in Killian Creek.
• The discharge of waste water by LCTS occurred on 294 of 2465 days (<12%) from
• October 1994 through October 2000. The maximum number of days that waste water
was discharged was 18 days in June 1998 and corresponded to the maximum monthly
total volume of waste water discharged (3.164 mg). The volume of waste water
discharged ranged from 0.005 mgd on February 15, 1995 to 0.412 mgd on August 4,
1995. No adverse impact associated with discharge of waste water by LCTS was
observed.
• All the macroinvertebrate bioclassifications were Good-Fair or Good except for that
from Forney Creek in 1995 when it was Fair. The highest number of
Ephemeroptera+Plecoptera+Trichoptera (EPT) taxa was found below LCTS every
year except 1997 (the same high number was collected below and above LCTS in
1998). There was no consistency among locations in terms of the biotic index scores
except that they indicated the Forney Creek macroinvertebrate community was the
most tolerant to pollution every year of the study.
• The fish community in Anderson, Forney, and Killian Creeks is typical for Piedmont
streams in Lincoln County, North Carolina, and is similar to that reported from other
• studies. The fish community near LCTS represents seven families and encompasses a

• range of trophic groups including planktivores, insectivores, specialized insectivores,
omnivores, and piscivores.
• Pollution tolerant species .comprise an extremely small component of the fish
community in streams near LCTS. The fish community has exhibited no 'visible
impact on the number of fish species or fish biomass during construction and
operation of LCTS. Comparison of LCTS operation and environmental monitoring
data indicate that balanced and indigenous populations continue to exist in Killian
Creek in the vicinity of LCTS and supports renewal of the LCTS NPDES permit.

• CHAPTER 1
INTRODUCTION
Per agreement with the North Carolina Department of Environment and Natural Resources
(NCDENR), annual monitoring of macroinvertebrates and fish at selected locations in
Anderson, Killian, and Forney Creeks of the Catawba River basin has continued since the
initial request to construct in Lincoln Combustion Turbine Station(LCTS) in 1990 (Figure 1-
1). The objective of this on-going monitoring program is to provide data to assess balanced
and indigenous populations with respect to operation of LCTS and evaluate renewal of the
Station NPDES permit(NC0080781).
The Lincoln Combustion Turbine Station is located approximately 18 mi northwest of
Charlotte in Lincoln County, North Carolina (Figure 1-1). Stream stretches of Anderson and
Killian Creeks border the 711 acre LCTS site in the Catawba River basin (Hydrologic Unit
03050102). The sixteen independent simple cycle combustion turbine units have a combined
nameplate capacity of 1152 MW. Each unit is rated at 72 MW. The water intake and
• discharge structures of LCTS are located on Killian Creek. Withdrawal and discharge of
water occurs intermittently corresponding to operation cycles of LCTS to help meet customer
electricity needs during peak demand times.
Review of past studies by regulators have determined that the intake and discharge of water
by LCTS assures the protection and propagation of a balanced, indigenous populations in the
adjacent creeks of the Catawba River basin (Duke Power Company 1990). This report
presents data collected from 1990 through 2000. Also these data were compared with other
past and present on-going environmental monitoring programs conducted in this watershed.

STATION OPERATION
BACKGROUND INFORMATION
Water withdrawal and discharge by Lincoln Combustion Turbine Station (LCTS) from
Killian Creek occurs intermittently based on customer electrical demand for station
operation. Per agreement with NCDENR, water can only be withdrawn from Killian Creek
when flows are above 7Q10 (estimated as 2.28 cfs), and no more than 25%of the flow can be
withdrawn with a maximum withdrawal of 10 cfs (6.46 mgd). The flow of Killian Creek is
monitored at USGS gage #0214269560 that was installed in 1990 near the intake of LCTS
and on the opposite bank, 1,000 ft upstream from Forney Creek (Figure 1-1). The intake
structure consists'of a concrete chute and an attached sump in which pumps are mounted.
The threshold between the sump and the chute prevents water from Killian Creek entering the
sump during periods of low stream flow. Following operation of LCTS units, water
withdrawn at the intake structure is pumped to the raw water storage pond, as needed to
• replenish the water supply for future operation. The capacity of the raw water storage pond is
approximately 50 mg and covers approximately 9.5 acres. An annual report detailing the
date and volume of water withdrawn by LCTS and respective Killian Creek flow is sent to
NCDENR.
The waste water treatment system receives discharge from LCTS sumps, clarifier, and
demineralizer neutralization tank. Effluent is collected in the inlet distribution channel and
routed to one of two basins. Each basin provides an estimated 24 hours of retention for
settling of suspended solids and removal of any entrained oil. The pH of the effluent can be
adjusted prior to discharge by the addition of acid or caustic. Operation of the waste water
recycle pump ensures thorough mixing prior to discharge. After pH adjustment, the effluent
is discharged to Killian Creek downstream of the LCTS intake structure (Figure 1-1). The
waste water effluent is sampled and analysis submitted monthly to NCDENR as required by
the NPDES permit of LCTS.

• OPERATION DATA
From October 1990 through September 1999, the minimum monthly flow of Killian Creek
occurred in 11 of 12 months in 1999 with the lowest flow of 3.77 cfs (2.44 mgd) in
September 1999 (Table 2-1). The maximum daily average withdrawal from Killian'Creek
monitored and reported to NCDENR was 1.32 cfs (0.852 mgd). The volume of water
withdrawn by LCTS was well within the limitations of the agreement with NCDENR. The
design of the LCTS intake structure assures continuous stream flow in Killian Creek.
The discharge of waste water by LCTS occurred on 294 of 2465 days (<12%) from October
1994 through October 2000 (Figure 2-1), The maximum number of days that waste water
was discharged was 18 days in June 1998 and corresponded to the maximum monthly total
volume of waste water discharged(3.164 mg). The volume of waste water discharged ranged
from 0.005 mgd on February 15, 1995 to 0.412 mgd on August 4, 1995 (Figure 2-2). No
adverse environmental impact associated with discharge of waste water by LCTS was
observed.

BIOLOGICAL EVALUATION
MACROINVERTEBRATES
Methods and Materials
Macroinvertebrate samples were collected in the vicinity of the Lincoln Combustion Turbine
Station (LCTS) in August of each year from 1991 through 1999. Four locations were
sampled in 1991, 1992, and 1993. Three were in Killian Creek below the project at Old
Plank Road (SR 1511), and in the project area immediately below and above the confluence
with Forney Creek. The fourth sampling location was in Forney Creek immediately above
the confluence with Killian Creek. A fifth location above the project in Anderson Creek was
added in 1994, about one mile above its confluence with Killian Creek. The two streams are
very similar in terms of habitat and substrate (Table 3-1). Samples collected in 1992 were
not identified due to a problem with preservation. The bioassessment protocol developed by
North Carolina Department of Environment and Natural Resources (NCDENR) biologists
• was used to collect samples and compare communities at the two locations and assign
bioclassifications. These bioclassifications are based on scores assigned for the number of
Ephemeroptera+ Plecoptera+ Trichoptera (EPT) taxa, and the scores for the weighted mean
biotic index for all taxa (NCDEHNR 1997). The biotic index scores for individual taxa are
assigned by NCDENR biologists, and are an indication of each taxon's sensitivity to
pollution.
Results and Discussion
All the bioclassifications were Good-Fair or Good except for that from Forney Creek in 1995
when it was Fair (Table 3-1, Figures 3-1 and 3-2, Appendix Tables A-1 through A-8).
Overall bioclassifications tended to be lower for Forney Creek samples and higher for
samples collected below LCTS. The highest number of EPT taxa was found below LCTS
every year except 1997 (the same high number was collected below and above LCTS in
1998). In 1997 below LCTS, the portion of the stream bank adjacent to the pipeline crossing
had been tilled and was still bare of vegetation at the time of sampling. Silt at that sample
location was more prevalent than usual in 1997, and this probably explains the historically
low number of EPT there. There was no consistency among location in terms of the biotic
• index scores except that they indicated the Forney Creek macroinvertebrate community was
the most tolerant to pollution every year of the study.

The results of the macroinvertebrate monitoring do not reveal any effects from the operation
of LCTS.
FISH
Methods and Materials
Fish were collected at seven stream locations in the vicinity of the Lincoln Combustion
Turbine Station (LCTS) in late August or early September from 1990 through 2000.
Collection locations and techniques were similar to those used in 1989 (Duke Power
Company 1990). Fish were collected with backpack electrofishing equipment and population
numbers were estimated with multiple pass depletion methodology (Raleigh and Short 1981).
One or two electrofishing units were used, based on stream width, to achieve adequate
coverage. Stream segments were approximately 100 m long and were measured for total
length and width (every 10 m) to calculate the area sampled (hectares). To prevent fish
• movement into or out of the stream reach during sampling, the sample segments were
blocked with nets at the upstream and downstream ends. All collected fish were identified,
weighed (g), and measured (mm). Large fish were released well downstream of the sample
area and small fish were preserved in 10% formalin for taxonomic identification in the
laboratory. Generally, three electrofishing passes were sufficient to achieve depletion of the
resident fish populations, although additional passes were occasionally required. Water
temperature (°C) was measured at each location with a calibrated thermister. Dissolved
oxygen concentration (mg/L) was measured at each location with a dissolved oxygen probe
or by chemical titration.
Sampling locations consisted of one location downstream from the LCTS at the Plank Road
(SR 1511) crossing over Killian Creek (Location 740.0); one location on Killian Creek
adjacent to the LCTS property and below the confluence with Forney Creek (Location
742.0); one location on Killian Creek adjacent to the LCTS property and above the
confluence with Forney Creek (Location 743.0); one location on Forney Creek just above the
confluence with Killian Creek and adjacent to a rock quarry (Location 746.0); two locations
on the upper end of Forney Creek just below and above the Forney Creek Wastewater
• Treatment Plant (Locations 747.0 and 747.1, respectively); and an upstream reference site
(Location 748.0)on Anderson Creek,prior to entering the LCTS property (Figure 1-1).
•

•
The population size for each species was calculated with the MicroFish Program, Version 3.0
(Van Deventer and Platts 1989). The average weight of an individual fish and the total
weight for the estimated population of each species were calculated. Fish population
numbers and weight were adjusted for stream area to provide density and biomass
information. Individual species biomasses were combined for total fish biomass at each
location. Numbers of fish species, exclusive of hybrid complexes, are also presented.
Results and Discussion
A diverse fish community was present in the stream environments in the vicinity of the
LCTS. From 1990 through 2000, 36 species and two hybrid combinations, representing
seven families, were collected by electrofishing, compared with 27 species and two hybrid
combinations representing the same seven families in 1989 (Table 3-3 and Duke Power
Company 1990). From 1990 through 2000, electrofishing catches were numerically
dominated by cyprinids, followed in descending order by centrarchids, cyprinodonts,
ictalurids, catostomids, percids, and clupeids. This order of family abundance was similar to
• that found in 1989 except that the position of ictalurids and percids was reversed. These
families encompass a range of trophic groups including planktivores, insectivores,
specialized insectivores, omnivores, and piscivores.
The common carp was the only species collected in 1989 that was not collected from 1990 to
2000. The ten additional species collected from 1990 to 2000 included the yellowfin shiner,
swallowtail shiner, fathead minnow, snail bullhead, white catfish, channel catfish, green
sunfish, pumpkinseed, redear sunfish, and yellow perch and represented a very minor
component (< 0.4%) of the collected individuals. No rare or endangered species were taken
in the vicinity of the LCTS project from 1989 through 2000. Pollution tolerant species (i.e.,
common carp and green sunfish) comprised an extremely small component of the entire fish
community from 1989 through 2000.
The number of species collected at all locations ranged from 8 to 26 and averaged 16.9 from
1990 through 2000 (Table 3-4). Fourteen to 23 species were collected at these same seven
locations in 1989 for an average of 16.7 species. On an individual location basis, the average
• number of species collected from 1990 to 2000 at Locations 740.0, 742.0, 743.0, 747.1, and
748.0 were quite similar to that observed in 1989. Only at Locations 746.0 and 747.0 on
3-3

•
Forney Creek did the 1990 to 2000 average differ substantially (in a positive and negative
direction, respectively) from the 1989 value.
The number of species collected at the upstream reference location (748.0) ranged from 13 to
19 species while Locations 743.0 and 742.0 ranged from 14 to 22 and 13 to 23 species,
respectively. Location 740.0, the most downstream site, had species numbers ranging from
19 to 26. This downstream accumulation of species is to be expected as stream order
increases and would not indicate impact from the activities at LCTS.
Fish biomass was estimated at each location from 1990 to 2000, except in 1997 at Location
746.0 when the discharge of cement fines from a neighboring rock quarry prevented fish
sampling (Table 3-5, Appendix Tables B-1 to B-76). Fish biomass was variable and
exhibited no negative trends since the 1989 survey. Fish biomass at the upstream reference
location (748.0) ranged from 11.7 to 54.3 kg/ha (Figure 3-3). Fish biomass at the next
downstream location (743.0) ranged from 14.7 to 63.3 kg/ha and indicated a slight increasing
trend with high estimates during the drought years of 1999 and 2000 (Figure 3-4). Fish
biomass at Location 742.0 was variable, ranging from 18.1 to 111.7 kg/ha, and may have
• reflected activities impacting the Forney Creek watershed (Figure 3-5). As an example, fish
species numbers and biomass at Location 742.0 were low in 1997 and probably represented
impacts from the discharge of cement fines into lower Forney Creek. These fines were quite
basic, as indicated by a pH value of 10 measured on the side of Killian Creek directly
influenced by Forney Creek (pH measured by NCDENR personnel). Biomass at the most
downstream location (740.0) ranged from 34.0 to 190.2 kg/ha (Figure 3-6). Biomass
estimates at this location were influenced by occasional catches of several large gi73ard shad
or catostomids moving upstream from Dutchman's Creek and Lake Wylie. Fish biomass
generally increased from Locations 748.0 through 740.0,indicating the same increasing trend
with downstream direction as did fish species numbers. The three locations on Forney Creek
(746.0, 747.0, and 747.1) have been surveyed due to their potential to indicate watershed
activities that may impact fish communities in the vicinity of the LCTS (Figure 3-7).
The fish community in Anderson, Forney, and Killian Creeks is typical for Piedmont streams
in Lincoln County, North Carolina, and is similar to that reported by Louder (1964) from
other locations in Forney and Killian Creeks. Lemly (1985) identified similar species in first,
second, and third order streams of the Piedmont province of North Carolina. The LCTS fish
• community represents seven families and encompasses a range of trophic groups including
planktivores, insectivores, specialized insectivores, omnivores, and piscivores. Since the
3-4

• 1989 report (Duke Power Company 1990), ten additional species of fish have been collected
in Anderson, Forney, and Killian Creeks, although this increase is probably attributable to the
extensive sampling effort expended during these 11 years. Pollution tolerant species
comprise an extremely small component of the LCTS fish community. Indeed, the fish
community has exhibited no visible impact from LCTS on the number of fish species'or fish
biomass during construction and several years of operation. Because the fish community in
Anderson, Forney, and Killian Creeks is characterized by species diversity, sustainability
through cyclic seasonal changes, trophic level diversity, and a paucity of pollution tolerant
species, it is concluded that there is a balanced, indigenous fish community in the creeks
adjacent to the LCTS.
