Subject: NPDES Permit Issuance
CP&L Sutton WWTP
NPDES Permit No. NCOOOIL422
New Hanover County
Attached to this letter is the Snal NPDES permit for CP&L Sutton Steam Plant, NPDES
Permit No. NC0001422. This permit is issued pursuant to the requirements of North Carolina
General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the
U.S. Environmental Protection Agency dated May 9, 1994.
Based on your letter dated December 3, 2002, the following changes (and clarifications) have been
made to the permit from the draft permit:
• The minor errors (footnotes, etc.) have been corrected.
• For Outfall 001, the Division of Water Quality agrees with the proposed two-year compliance
schedule proposed by CP&L. The permit has been modified to reflect weekly monitoring for the
first two years. Unless CP&L demonstrates that selenium has no reasonable potential to
exceed the North Carolina acute value, the selenium limit will take effect February 1, 2005.
• For Outfall 004, the description has been changed to acknowledge that the discharge from 004
can occur to the cooling pond "and/or" to Outfall 001.
• As explained in your letter and through telephone conversations with Ms. Louise England, the
Division of Water Quality understands that even if a discharge occurs from Outfall 004, and is
diverted to the Cape Fear River, that discharge is subject to the limits and monitoring for 004
as well as 001. Because a selenium limit has been imposed on Outfall 001 (now revised to
allow a compliance schedule), the selenium limit for internal Outfall 004 will be eliminated.
Selenium monitoring for 004 will be reduced from weekly to monthly.
e The boilerplate language has been revised to include the EPA bypass definition. The
requirement to evaluate alternatives has been eliminated (most notably because alternatives
are not feasible for a discharge of this volume).

• As stated in the draft cover letter, CP&L should be aware that the Division of Water Quality is
currently in the process of adopting total residual chlorine as a water quality standard and will
be implementing total residual chlorine limits in new and renewal permits. This may effect
Outfall 001 with the next permit renewal. The NPDES Unit encourages CP&L to conduct total
residual chlorine monitoring at levels approaching the acute criteria of 28 ug/1.
If any parts, measurement frequencies, or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request
within thirty (30) days following receipt of this letter. This request must be in the form of a
written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the office of Administrative Hearings, Mail Service Center 6714, Raleigh, North Carolina
27699-6714. Unless such a demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division of
Water Quality. The Division of Water Quality may require modification or revocation and
reissuance of the permit.
This permit does not affect the legal requirements to obtain other permits which may be required
by the Division of Water Quality, the Division of Land Resources, the Coastal Area Management Act, or
any other federal or local governmental permit.
If you have any questions regarding the NPDES permit, please contact Susan Wilson at

A. (5) ACUTE TOXICITY MONITORING (Monthly)
The permittee shall conduct acute toxicity tests on a monthly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater
and Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales
promelas) 24-hour static test, using effluent collected as a grab sample. Effluent samples for self-
monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The test will be performed once per month in each month in which a discharge occurs.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Form (MR -1) for the month in which it was
performed, using the appropriate parameter code. Additionally, DWQ Form AT -1 (original) is to be sent
to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate that there is a reasonable potential for water quality standards
excursions in 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 and appropriate environmental controls, shall constitute an invalid test and will
require immediate retesting (within 30 days of initial monitoring event). Failure to submit suitable test
results will constitute noncompliance with monitoring requirements.
Permit NC0001422

A. (6) GROUNDWATER MONITORING
The permittee shall, upon written notice from the Director of the Division of Water Quality, conduct
groundwater monitoring as may be required to determine the compliance of this NPDES permitted
facility with the current groundwater Standards.
1. Monitor wells (2C, 4B, 5C, 6C, 7C, 8, 9, 10, 11 and 12) shall be sampled every March for the
following parameters: Water Levels, pH, Arsenic, Iron, Total Dissolved Solids, Chlorides and Selenium.
The measurement of water levels must be made prior to sampling for the remaining parameters. The
depth to water in each well shall be measured from the surveyed point on the top of the casing.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the
relative elevation of the measuring point for each monitoring well.
The results of the sampling and analyses shall be sent to NC DENR / DWQ / Groundwater Section,
Permits Group, P.O. Box 29578 Raleigh, N.C. 27626-0578 on form GW -59 [Compliance Monitoring
Report Form], in sufficient time that the forms will have been received by the last day of April.
2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
3. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L,
Groundwater Classifications and Standards. The Compliance Boundary for the disposal system
constructed prior to December 31, 1983 is established at either (1) 500 feet from the waste disposal
area, or (2) at the property boundary, whichever is closest to the waste disposal area. An exceedance
of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems
midway between the Compliance Boundary and the perimeter of the waste disposal area. Any
exceedance of standards at the Review Boundary shall require remediation action on the part of the
permittee.
A. (7) DISE INTEGRITY
The permittee shall check the dike areas for leaks by a visible inspection and shall report any seepage
detected.
A. (8) BEST MANAGEMENT PRACTICES PLAN
The Permittee shall continue to implement a Best Management Practices (BMP) Plan to control the
discharge of oils and the hazardous and toxic substances listed in 40 CFR, Part 117 and Tables II and
III of Appendix D to 40 CFR, Part 122, and shall maintain the Plan at the plant site and shall be
available for inspection by EPA and DWQ personnel
A. (9) INTAKE SCREEN BACKWASH
Continued intake screen backwash discharge is permitted without limitations or monitoring
requirements.
Permit NC0001422

A. (10) NO DISCHARGE OF PCBs
As specified by 40 CFR 423.13 (a), there shall be no discharge of polychlorinated biphenyl compounds
such as those commonly used for transformer fluid.
A. (11) BIOCIDE CONDITION
The permittee shall obtain authorization from the Division of Water Quality prior to utilizing any
biocide in the cooling water. The Permittee shall notify the Director in writing not later than ninety
(90) days prior to instituting use of any additional biocide used in treatment system which may be
toxic to aquatic life other than those previously reported to the Division of Water Quality. Such
notification shall include completion of Biocide Worksheet Form 101 and a map locating the discharge
point and receiving stream. Concentrations of chromium, copper, or zinc added to biocides shall not
exceed applicable water quality standards or action levels in the receiving stream, as determined by
calculations from the Biocide Worksheet Form 101 with Supplemental Metals Analysis worksheet.
A. (12) FISH STUDY AND MONITORING
The baseline study for the fish monitoring has been completed and approved (1999). This was
required based on the re-routing of Outfall 004 to the Cape Fear River. Fish tissue analysis will be
performed annually (after Outfall 004 is discharging to the Cape Fear River). All contaminant data
collected as part of this monitoring requirement will be reported within 4 months after sample
collection. Should fish tissue levels indicate concentrations of concern, the Division of Water Quality
may require additional collection of environmental data.
This monitoring plan is an enforceable part of the NPDES permit.
Permit NC0001422

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 coliform 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.
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.
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.

NC0001422 Boilerplate

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. jWs 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
(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.

NC0001422 Boilerplate
Page 4
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

SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Certified Operator
Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the
facility by the Certification Commission, the permittee shall employ a certified wastewater
treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such
operator must hold a certification of the grade equivalent to or greater than the classification
assigned to the wastewater treatment facilities by the Certification Commission. The permittee
must also employ a certified back-up operator of the appropriate type and any grade to comply with
the conditions of Title 15A NCAC Chapter 8G .0200. The ORC of the facility must visit each Class I
facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and
holidays, and must properly manage and document daily operation and maintenance of the facility
and must comply with all other conditions of Title 15A, NCAC Chapter 8G .0200. Once the facility
is classified, the permittee shall submit a letter to the Certification Commission which designates
the operator in responsible charge within thirty days after the wastewater treatment facilities are

conditions of the permit.

NC0001422 Boilerplate
Page 7
3. Need to Halt or Reduce not a Defense
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 intentional 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.
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 Il, 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. p) 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

NC0001422 Boilerplate
Page 8
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.
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 DWQ 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
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the
volume and nature of the permitted discharge. Samples collected at a frequency less than daily
shall be taken on a day and time that is characteristic of the discharge over the entire period which
the sample represents. All samples shall be taken at the monitoring points specified in this permit
and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream,
body of water, or substance. Monitoring points shall not be changed without notification to and
the approval of the Permit Issuing Authority.

AMENDMENT TO ORIGINAL FACT SHEET (Based on comments submitted by CP&L, dated
12/3/02)
Corrected minor comments (boiler plate, footnotes)
Outfall 001 - With concurrence from EPA Region IV (Karrie-Jo Shell), gave CP&L a 2 year
compliance schedule to meet the new acute selenium limit. This will allow CP&L additional
time to sample more frequently and better characterize the selenium issue. Because this is a
new limit, NC does not object to a reasonable compliance schedule. Monitoring will remain at a
weekly frequency. The permit was corrected to allow for this compliance schedule
Dilution will not be allowed for the acute limit (NC does not allow dilution to protect for acute
effects)
Outfall 004 - As explained by CP&L, even if 004 (the internal ash pond discharge) discharges
singular to Outfall 001, the permittee is required to comply with the limits at 004 and 001
(sampled at the combined junction basin). This permit writer was not aware of that when the
selenium limit was placed on the internal outfall 004. Since this is the case (and the permittee
will have to comply with the selenium limit at 001), NC agrees to eliminate the limit on the
internal outfall 004. Monitoring will be reduced to monthly.
NC agrees to modify the permit boiler plate language to specify the federal definition of
"bypass".

From: Susan A Wilson <[e-mail]>
Organization: NC DENR DWQ
To: [e-mail]
Karrie-Jo,
I received some comments back from CP&L Sutton (NC0001422) re. the issue
with the Selenium acute limit that I placed in the permit. They have
requested a 2 year compliance schedule in order to better characterize
selenium ( 1 YR), then implement appropriate corrective action (another
year). I think this is appropriate because the selenium acute value
(NC's) used is actually based on selenate (+6) and not total. We are
limiting as a total (and we're on fairly shaky legal ground with it).
This would provide them some time to determine which selenium form is
prevalent in the water column and to monitor more frequently to
determine if there is a problem. This is for outfall 001, which is the
discharge from the large cooling pond to the Cape Fear River..
Also, in the draft permit I placed a selenium limit on Outfall 004.
This is the discharge from the new ash pond which will sometimes
discharge out outfall 001 (and not to the internal outfall to the large
cooling pond). I put this limit in to protect for those occasions that
there may be a discharge from 004, independent of 001. They explained
that even if 004 discharges independently of 001, they would have to
meet the limits specified in 001 (as this is the compliance point for
discharge to the river). I was not entirely certain of that at the time
I placed the WQ specific limit for selenium on 004. Since this is the
case, I would agree with elimination of the selenium limit on 004 (since
there is a selenium limit on 001). I would also be more specific in the
permit that if 004 discharges to the river (when 001 from the cooling
pond is not discharging) they still have to comply with the limits of
001 (which is anything discharging directly to the river). How does
this sound to you?
In a nut shell - some of the changes that they requested that I agree
with:
- Remove selenium limit at 004 (and reduce monitoring to monthly), since
this outfall will have to comply with the limit at 001
- Give a 2 year compliance schedule for the selenium limit at 001
Due to our backlog issues, I was going to try very hard to issue this
before I go on vacation (next week). If there is any way you could
respond (and believe me, I know everyone's trying to get permits issued
by the end of the year) - I'd really appreciate it.
Thanks Karrie-Jo. I know this is confusing - give me a ring if you need
to. 919-733-5083, ext. 510.

Draft NPDES Permit Comments
Dear Ms. Susan Wilson:
Enclosed are our comments on the draft NPDES permit for Sutton Steam Electric Plant, NPDES Permit No.
NC0001422. We appreciate the opportunity to comment.
In addition, the ash sluice water pump for Units 1 and 2 was recently replaced. The new pump has a higher
pump capacity than that of the old pump. An average discharge flow from Outfall 004 (ash pond discharge)
was calculated on a limited data set and found to be 3.561 MGD.
If you have any questions please contact Ms. Louise England, Senior Environmental Specialist in the
Environmental Services Section with CP&L at [phone].
Certification per Section B.11.c of our permit:
"I certify, under penalty of law, that this document and all attachments were prepared under my direction or

Draft NPDES Permit Comments
NPDES Permit Cover Sheet
• CP&L notes that Part IV should be added to the sentence ending: "in accordance with the discharge
limitations, monitoring requirements, and other conditions set forth in Parts I, II, and III, hereof."
PART I
Section A.M. — Effluent Limitations and Monitoring Requirements
• The note associated with Total Residual Chlorine should be 3 instead of 4.
• The note associated with Acute Toxicity should be 4 instead of 5. ✓
• CP&L requests that the requirement to monitor and report Total Selenium on a weekly basis be
revised to a monthly basis. Monitoring Total Selenium on a monthly frequency should provide the
needed data to evaluate the Total selenium in the discharge from Outfall 001. In addition, weekly
monitoring is costly for the sample analysis and burdensome for plant personnel collecting the more
frequent samples. rNow-rolZ, wKIwf?
• The limit of 56 µg/1 for Total Selenium does not take into account any dilution provided by the Cape
Fear River. CP&L requests that this dilution by the Cape Fear River be used when calculating a limit
for the discharge of Total Selenium from Outfall 001. 110
• Because the Total Selenium limit of 56 µg/1 for this outfall is new, CP&L requests a Schedule of
Compliance of two years. In the past two years there have been limited opportunities to characterize
Total Selenium at this outfall. Therefore, CP&L would like to collect data for one year in order to o k
evaluate monthly and seasonal variability and then have one year to implement corrective actions if
needed. Also, during this two year period CP&L may take the opportunity to evaluate the dilution
provided by the Cape Fear River.
• The statement prohibiting the discharge of polychlorinated biphenyl compounds is also stated in DK -
Section A.(10). CP&L requests that the statement in A.(1) be deleted.
Section A.M. — Effluent Limitations and Monitoring Requirements
• CP&L requests that the sentence authorizing the discharge of Outfall 004 to the Cooling Pond or to
Outfall 001 be revised. Outfall 004 can discharge to both the cooling pond and to Outfall 001 pk
simultaneously. CP& -L suggests the sentence be revised to read "...to the Cooling Pond and/or to
Outfall 001...".
• CP&L requests that the limit of 56 µg/1 for Total Selenium be eliminated for Outfall 004 (new ash
pond discharge). Outfall 004 is an internal outfall which discharges either to the cooling pond, to the OV -
Cape Fear River, or to the cooling pond and Cape Fear River simultaneously through Outfall 001 and Ac ti "o
should not be subject to this limit. We also request that monitoring of this outfall for Total Selenium
be reduced to the current NPDES Permit's requirement of quarterly.
• If the Total Selenium limit of 56 µg/1 is not eliminated, CP&L requests a Schedule of Compliance of
three years. In the past two years there have been limited opportunities to characterize Total Selenium N/A
at this outfall, especially in relation to the bypass line that conveys ash pond discharge water to Outfall r
001. Therefore, CP&L would like to collect data for one year to evaluate seasonal variability and then
have two years to implement the predicted extensive and costly corrective actions if needed.

Draft NPDES Permit Comments
PART H
Section CA — Bypassing of Treatment Facilities
• a.(1) — The DWQ defines a bypass as "the known diversion of waste streams from any portion of a
treatment facility including the collection system, which is not designed or established or operating
mode for the facility." Since neither the NC Statutes nor the DENR regulations contain a definition of
bypass, other than a bypass in reference to pretreatment, the definition of bypass should default to the
federal definition. The EPA defines bypass as "... the intentional diversion of waste streams from any
portion of a treatment facility." Although the difference between these definitions may appear to be
subtle, the meaning of the definition in the proposed permit in regard to the reporting requirements
and liabilities associated with the NPDES permit are, in CP&L's belief, significant and excessive
beyond that authorized by law and regulation. CP&L requests that the proposed definition in the
proposed permit be replaced by the EPA definition or that the DWQ inform CP&L that the proposed
definition is to be interpreted as the EPA definition.
PART III
Section D. — Requirement to Continually Evaluate Alternatives to Wastewater Discharges
• This requirement is inappropriate for this facility and is essentially impossible to comply with since a
permittee cannot continually evaluate all wastewater disposal alternatives.

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NC0001422, CP&L Sutton
SUMMARY
CP&L - Sutton Plant is a coal fired steam electric generating plant (3 Units , total net capacity
of 613 MWe; 3 internal combustion turbines, total net capacity of 64 MWe). 'Me site has 2
ashponds and an 1100 acre cooling pond.
CP&L submitted EPA application forms 1 and 2C (received July 2, 2001) for renewal of their
current permit. The previous permit was issued July 31, 1996 and expired June 30, 2001 (a
modification was issued October 19, 1998). The facility is currently operating under its
expired permit.
CP&L has the option of routing part of the treated wastewater from Outfall 004 directly to the
Cape Fear River and/or directly to the cooling pond (and subsequently discharging from Outfall
001). Even when Outfall 004 is routed to the Cape Fear River, sampling is conducted at Outfall
001 (i.e., Outfall 004 is combined with Outfall 001 prior to sampling for Outfall 001; sampling
for Outfall 004 will still be conducted as required). This has been previously approved and the
Division has no objections to this as long as permitted limits are maintained. CP&L was also
required to perform fish monitoring when the discharge becomes more continuous (a baseline
study was performed in 1999).
The facility is regulated by federal effluent guidelti�ttl�t��F��,�sr sett
Generating Point Source Category) - BPT/ BAT. t
This portion of the Cape Fear River (below Lock and Dam #1) is listed as impaired due to low
dissolved oxygen levels. Sources of the impairment are suspected to be cumulative point
source impacts and nonpoint source pollution. There is also speculation that drainage of
swamp waters, with naturally occurring low D.O. levels, may be contributing to the
impairment. The Division is currently collecting data in this area to develop a TMDL. The
Division has recommended tertiary limits for new or expanding discharges of oxygen
consuming waste.

Because the discharge from CP&L-Sutton does not have oxygen consuming wastes, this should
not effect its effluent limits.
Outfall OCA - cooling pond discharge, recirculated cooling water, non -contact cooling water,
and treated wastewater from internal Outfalls 002, 003, and 004.
This outfall will be renewed with requirements based on 40 CFR 423.13 (b)(I)(2)-BAT. Because
this outfall is a direct discharge to the Cape Fear River, some parameters of concern will continue
to be monitored and this outfall will continue to have a toxicity testing requirement pH is limited
at this outfall - due to the direct discharge.
Outfall 002-0- wastewater associated with the old ash pond, which discharges to the cooling
pond (and subsequently, outfall 001). May consist of low volume waste, yard drains, oily waste
treatment, ash sluice, coal pile runoff and treated wastewater from Outfall 003.
This outfall will be renewed based on 40 CFR 423.12 (b)(3 and 4) - BPT. This is not a direct
discharge so no parameters are water quality limited. However, arsenic and selenium are
parameters of concern and will continue to be monitored.
Outfall 003$ wastewater associated with chemical metal cleaning wastes (for cleaning the
boiler tubes as necessary every 5 to 10 years). Chemical metal cleaning wastes are usually
stored on-site for disposal by evaporation. If this is not done, the chemical metal cleaning
wastes may be treated then discharged via outfall 003 to the old ash pond (or to the new ash
pond, and subsequently, 004).
This outfall will be renewed based on 40 CFR 423.13 (e) - BAT. This is not a direct discharge, so
no parameters are water quality limited.
Outfall 004 - wastewater associated with the new ash pond. This wastewater can discharge
directly to the Cape Fear River via Outfall 001, or directly to the 1100 acre cooling pond via
Outfall 004. Per CP&L, during this next 5 year permit cycle, it is expected that the new ash
pond will discharge more routinely via Outfall 001 (several times per week to daily). Even when
discharging to Outfall 001 - wastewater from the new ash pond may also be discharging to the
cooling pond. May consist of low volume waste, yard drains, oily waste treatment, ash sluice,
coal pile runoff and treated wastewater from Outfall 003 (this is the same as the old ash pond,
Outfall 002).
This outfall will be renewed based on 40 CFR 423.12 (b)(3 and 4) - BPT. Arsenic and selenium
are parameters of concern and will continue to be monitored.
TOXICITY TESTING:
Current Requirement: 24 hr Acute Monitoring (fathead minnow), LC50
(Due to the variability of the discharge, acute monitoring was given in the permit)
Recommended Requirement: Same as above
The facility has had an exemplary toxicity monitoring record (>99% for the past 4 years).
COMPLIANCE SUMMARY: BASED ON THE PREVIOUS 2 YEARS
There are no outstanding and/or chronic compliance problems related to the NPDES permit.
There have been no civil penalty assessments against the facility during the term of the permit.
CP&L has discharged very infrequently from Outfall 001 in the past three years.
INSTREAM MONITORING:
The facility is a member of the Lower Cape Fear Basin Association and instream monitoring is
waived as long as CP&L continues to be a member of the Association.
CP&L Sutton NC0001422

Upstream and downstream monitoring data were reviewed. Temperature and dissolved oxygen
were not in violation of the standards.
PROPOSED CHANGES:
A reasonable potential analysis was conducted for Outfalls 001 and 004. There were no
discharges from Outfalls 002 and 003 during the previous 3 years.

be implemented as a limit. CP&L may provide documentation in the future of the division
between selenite and selenate; also, the use of a lower detection level for selenium during this
next permitting cycle may benefit CP&L in review of the data.
The permit application was reviewed and those values listed in the application were compared
with available acute values (for those parameters above detection level). No parameters, other
than arsenic, copper, residual chlorine, and selenium appeared to approach or exceed available
acute values.

Outfall 001 has a mixing zone for temperature. The company has stated that they would like to
retain this. Temperature data was reviewed - no problems were noted. This mixing zone was
approved many years ago and documentation has been difficult to locate. Due to the sporadic
nature of the discharge - the NPDES Unit recommends this be retained.

Thanks for the update. The residual chlorine starting the next permit cycle will give plant personnel time to buy an
amperometric titrator and have a database by the time the next permit application rolls around.
Attached is the information that we talked about earlier. The power point slide shows where CP&L has collected samples and
analyzed for selenium in relation to the ash pond discharge and Outfall 001. Please give me a call if you have any questions.
Thanks,

Subject: CP&I. Sutton
Louise,
Good news and bad news with regard to the draft permit. Spoke with Dave
today about the permit - he is very much wanting this one out to notice
before I leave - which I think I'll be able to do.
As far as residual chlorine - he said since that limit is not in effect
until 4/1/03 - we will not implement in permits prior to the Neuse
basin. However, be aware that upon Sutton's next renewal, if residual
chlorine is an issue, a limit may result (this should provide CP&L an
opportunity to devise an appropriate method to be used on outfall 001 -
and research the interference issue).
For selenium - I will likely put a limit of 56 ug/1 in the permit. If
CP&L can justify a compliance schedule - we are open to that. However,
for your benefit - the faster you can devise one the better. If you
need a year, please provide some justification - I'm unsure how EPA will
react. I'll send our documentation on the selenium out to you with the
draft permit (Wed. is my cutoff date for submitting permits for notice).
Thanks. I will be in the office for the rest of today and I will be
here tomorrow.

1. The certification of completion for the ATC which routed the effluent from the new ash pond to the
Cape Fear River was sent to DWO in a letter dated 6-30-99
2. A fish monitoring plan was submitted 1-6-99. The baseline study data was submitted 2-1-99
3. 1 have been unable to determine what "normal" alpha and beta values are. I can only compare
Sutton's to the other CP&L plants.

4. Plant personnel at Sutton have expressed concern with the values they are reporting for total
residual chlorine. There is apparently some type of positive interference with their DPD test.
Even on the days that bromine/chlorine is not added, they can get readings of 40 to 50 ppb TRC.
Because of the distance and the amount of time it takes to travel from the circ water discharge to
the discharge to the Cape Fear River there should be no chlorine in the water that is discharged
to the river. We will be performing further studies.
5. 423.12b.10. —After reading this it appears that this is in the event of a rainstorm greater than the
10 year, 24 hour storm that the coal pile runoff is designed to handle, - any water not treated is
not limited. I spoke with Fred Holt and he said that Sutton does not have limits for coal pile runoff
since it is routed to an ash pond which had more stringent TSS limits.
6. 423.13d.1 — This is for cooling tower blowdown. Sutton does not have cooling towers.
7. CP&L does monitor selenium in fish tissue. It was recognized several years ago that there was
elevated concentrations of selenium in the sediment of the cooling pond and in the fish tissue.
The measured selenium concentrations have not reached levels that have caused an observed
effect on the fish populations.
8. 1 have looked through our files and it appears that EPA had sent a draft permit in 1975. Before it
was issued the program was taken over by the State of North Carolina. The earliest NPDES
permit I have found was issued in 1977 and contained the mixing zone language. CP&L would
prefer to keep this mixing zone language in the permit.
9. Below is a table with discharge data for Outfall 001 from 1997 to present. There is not a lot of
data - most of the time there was no discharge from Outfall 001. After some research I found
that the November 2000 selenium concentration of 83 ppb was from a sample collected from
Outfall 001 when the ash pond was discharging to the Cape Fear River with no cooling pond
water used for dilution. This type of discharge occurred in October and November of 2000 only.
Also below is a table with selenium data collected within the cooling pond. The sampling point is
shown in the power point file attached to the email.

Wendy, I have no idea what are the specifics they may be asking for. However, in our 1997 annual
environmental monitoring report we have the following results for statewide average gross beta and alpha
levels:
Average Gross Beta -4.0 pCi/L
Average Gross Alpha -1.0 pCi/L
Since there were no error terms listed with this, I checked another reference, the Nationwide Occurrence of
Radon and Other Natural Radioactivity in Public Water Supplies(EPA 520/5-85-008). While this is
representative primarily of groundwater, there were some surface water supplies included. The results
were:
Gross Alpha Values for NC:
0.9 +/1.6 pCi/L(Arithmetic Mean +/ Standard Deviation)
0.3 +/ 6.5 pCi/L(Geometric Mean +/ Geometric Standard Deviation)
Gross Beta Values for NC:
4.2+/3.4 pCi/L(Arithmetic Mean +/ Standard Deviation)
3.1+/2.2 pCi/L(Geometric Mean +/ Geometric Standard Deviation)
In the 1995 ERS Report on Environmental Monitoring Around the Harris Site(Preoperational Phase) the
maximum gross alpha and beta results from the Harris Lake and Cape Fear Sites were:
Gross Alpha(Maximum)1.67+/1.16 pCi/L
Gross Beta(Maximum)5.02+/0.71 pCi/L
The average gross alpha and gross beta values for our preoperational monitoring were:
Gross Alpha(Average)0.45+/0.50 pCi/L
Gross Beta(Average)3.39+/0.89 pCi/L
As a matter of interpretation, there probably not be evidence of a problem as long as the value is no more
than the average plus three times the associated error. Since this was results from a preoperational program
for Harris you could probably say as long as it's no more than the maximum value plus 3 times the error.
This would guarantee that you're not looking at variations in the "noise" of background but have a real
"signal" from some specific radioactive material. Hope this helps, and let me know if you have any
questions. dale

Wendy - I sent this note to Roy Byrd and he refered me to you. This
data was from a discharge (meaning it is effluent wastewater data). l
have no idea if these values are typical or not. Could you enlighten
me?
Roy -
I know this is probably out of your area - but I couldn't figure out
who's area it would be under. I have some data from CP&L that was
necessary for their permit renewal application. They had to test for
alpha and beta radioacitivity and came up with values of 7.36 pci/l and
11.8 pci/l, respectively (this is from a coal burning plant). Do you
have typical background levels for these parameters? (or do you know
who I may need to talk to?). Thanks!

As you probably know, we're kind of "in between" coalition coordinators
(i.e., that position's been vacant for a few months), but Steve has been
working on pulling together and reviewing the coalition data sets. I.11
check with Jay and Steve and see what we can do for you. I think that both
of them are out of the office until Tuesday though.

I am still compiling data and error checking the data from the Lower Cape Fear River Program
I only have data for Station 89030000 (IC) beginning Jan. 1999. Are their data prior to this date?
Depths through 1998 were submitted in feet. I have coverted these to meters.
In addtion, time was not included as part of the data submittals until 1999
Depths of "0" represent surface measurements.
I included pH, conductivity and salinity values too.

SODIUM HYPOCHLORITE USAGE REQUEST
Dear Mr. David Goodrich:
Michael Shawn Longfellow
Plant Manager
As was discussed on May 10, 2002, between Susan Wilson of your unit and Louise England of
CP&L, Sutton Steam Electric Plant's (NPDES Permit No. NC0001422) Unit #3 bromination
equipment, which is used to control biofouling in heat exchangers, requires maintenance. Plant
personnel will use 13-15% sodium hypochlorite for biofouling control during the time the
bromination equipment is out of service. It is estimated that chlorination will occur three times per
week with approximately 250 gallons of sodium hypochlorite used per month. After maintenance
is completed, Spectrus OX1200 (1-bromo-3-chloro-5, 5-dimethylhydantoin) will again be used for
biofouling control.
In addition, the NPDES permit renewal application submitted July 2, 2001, identified the
bromine/chlorine solution as Biotrol 88P. Since the time of the submittal, Biotrol 88P has been
renamed Spectrus OX1200. No changes have been made to the chemical itself.
If there are any questions, please contact either R. Kent Tyndall, Environmental Specialist at
CP&L's Sutton Steam Electric Plant, phone [phone]; or S. Louise England, Senior
Technical Specialist in the Environmental Services Section with CP&L, phone [phone].
Certification per Section B.11.c of our permit:
"I certify, under penalty of law, that this document and all attachments were prepared under my

Sutton old ash pond weir
Subject: Sutton old ash pond weir

To: "'[e-mail]"' <[e-mail]>
CC: "Moorefield, Bruce" <[e-mail]>,
"Tyndall, Kent" <[e-mail]>
Susan,
This email is to document our conversation on August 26, 2002 concerning raising the old ash pond weir height.
Sutton Plant personnel want to add 2 feet to the height of the weir from an elevation of 24 feet msl to an elevation of
26 feet msl. The maximum operating level of the pond is 26 feet msl with the crest of the dike at 28 feet msl. After
raising the weir to 26 feet msl there will still be 2 feet of freeboard. In our conversation on August 26th, you gave
Sutton Plant personnel permission to raise the height of the weir to 26 feet msl.
I also understand that you have begun working on the Sutton NPDES permit. Please give me a call if you have any
questions or would like to visit the plant.
Thanks for your help,
Louise England

CP&L Sutton
NPDES No. NC0001422
New Hanover County
This letter is offered in response to your letter dated April 16, 2002, regarding the disposal of
dredging materials into the Old Ash Pond at the Sutton Steam Plant. It is the Division of Water
Quality's understanding that the non -hazardous material will not raise the water level in the Old Ash
Pond to cause a discharge and that enough capacity exists in the Old Ash Pond to maintain this
activity, as well as any current uses required of the Old Ash Pond. Additionally, because the Old Ash
Pond discharges, as necessary, via internal Outfall 002 into the Cooling Pond, which discharges via
Outfall 001 into the Cape Fear River, no adverse water quality effects are expected from this activity.
Both Outfall 002 and Outfall 001 must comply with the limits given in the current and any subsequent
permits. Please be advised that the Division of Water Quality grants this permission based on
knowledge of water quality issues and permitting only. Other permits outside the scope of the Division
of Water Quality may be required for this activity.
You may contact Susan A. Wilson at (919) 733 - 5083, ext. 510 should you have further
questions regarding this issue.

DREDGING ACTIVITIES
Dear Mr. David Goodrich:
As discussed in a conversation on March 28, 2002 with Susan Wilson of your group and Louise
England, Sr. Technical Specialist located at CP&L's HEEC, Sutton Plant will be dredging an
onsite barge slip. The dredged material from this barge slip will be conveyed to the Old Ash Pond
(NPDES Permit No. NC0001422, outfall 002). The current water level in the Old Ash Pond is
approximately 6 feet law-cr than the riser pipe, therefore there is no discharge from this outfall at
this time. Approximately 37 million gallons of water/spoil will be discharged into the Old Ash
Pond of which approximately 25,000 cubic yards will be spoil material. The addition of this
amount of water will not raise the water level in the Old Ash Pond to the point that a discharge
will occur. The Old Ash Pond contains an area of approximately 68 acres. Assuming only 30
acres of the pond is used to hold the sluiced water and spoil material, the water level in the Old
Ash Pond would be raised by approximately 4 feet. The spoil material, once settled, is calculated
to add approximately 7 inches over the 30 -acre area. Dredging operations and conveyance will be
monitored to maintain the Old Ash Pond water level below the top of the riser pipe. The current
elevation of the Old Ash Pond riser pipe is 23.81 feet msl. The maximum design operating
elevation of the pond is 26.0 feet msl. The crest of the Old Ash Pond dike is 28 feet msl. The
dredging of the barge slip is expected to begin in September 2002.
CP&L would appreciate a reply to this letter by May 16, 2002. A quick response is needed so that
a disposal site for the spoil material may be designated on permit applications required for the
dredging project.

As a follow-up to a conversation on December 11, 2000, between Mark Hale of DWQ and Reid
Garrett of Carolina Power and Light Company (CP&L), the following information is provided.
Part III, L of NPDES Permit No. NC0001422 for Sutton Steam Electric Plant requires CP&L to
conduct a biological study plan. Per the plan the ash pond discharge to the Cape Fear River
must be in continuous operation for four months before post -operational samples can be
collected. Sutton Plant began continuous operation of this discharge in October of 2000,
therefore, the post -operational samples cannot be collected in 2000. CP&L plans to collect the
post -operational samples in 2001 to fulfill this annual requirement.
If you have any questions please contact Louise England at [phone] or Reid Garrett at
[phone].

c. Describe receiving stream features and pertinent
downstream uses:
Tidal river used for shipping and fishing. Receives
several discharges from major industries.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater to be permitted: No Limit
b. What is the current permitted flow limit? No Limit
c. Actual treatment capacity of current facility? No Limit
d. Date (s) and construction activities allowed by previous
Authorizations to Construct issued in the previous two
years: No ATC has been issued in the past two years. On
November 25, 1998, an authorization was issued for
construction of piping and modification of the outlet
structure to allow effluent from the new ash pond to be
discharged directly through outfall 001 as well as
discharging to the cooling pond.
e. Please provide a description of existing or substantially
constructed wastewater treatment facilities: All process
wastewater and collected stormwater ultimately enters the
1110 acre cooling pond. Water is recycled from the pond to
supply condensers and heat exchangers. Water in the pond
is supplemented with river water as needed and is
discharged several times per year as needed to control
conductivity and water level. The discharge may be done
more frequently in the future. Oily wastewater is
directed to a mechanical oil separator system. Two cement
retention basins receive all low volume waste, effluent
from the oily waste treatment system, and metal cleaning
waste that is not incinerated. Flow then goes to the old
ash pond which discharges to the cooling pond. The old ash
pond, 68 acres, receives flow from both retention basins
and coal pile and tank farm runoff . All ash sluice goes to
the 74 acre new ash pond which provides sedimentation and
pH control prior to discharge to the cooling pond. The
outfall structure from the new ash pond has been modified
to allow for a discharge to the cooling pond or directly
through outfall 001 to the river.
f. Please provide a description of proposed wastewater
treatment facilities: No changes are proposed.
g. Possible toxic impacts to surface waters: All wastewater,
except for the outfall from the new ash pond, is held in
the cooling pond for extended periods of time which allows

for oxidation and dilution of constituents. Annual
pollutant analysis indicates that toxicity is not a
problem.
h. Pretreatment Program (POTWs only): Not Needed
2. Residuals handling and utilization/disposal scheme: Ash can
be removed from the ash ponds and reused as approved by Permit
No WQ0006109. No other residuals are generated.
3. Treatment plant classification: Class II Physical/Chemical
4. SIC Code(s): 4911
Wastewater Code(s) Primary: 14, 68, 69, 70
Main Treatment Unit Code: 51500
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant
Funds or are any public monies (municipals only) involved? NA
2. Special monitoring or limitations (including toxicity)
requests: No The facility has had no problem with toxicity.
3. Important SOC, JOC or Compliance Schedule dates: NA
4. Alternative Analysis Evaluation: Has the facility evaluated
all of the non -discharge options available? Please provide
regional perspective for each option evaluated.
Non -discharge options are not practical. Discharge from the
cooling pond occurs infrequently but the discharge rate is
quite high.
PART IV - EVALUATION AND RECOM ONDATIONS
All waste sources ultimately are discharged to the cooling
pond from which wastewater has been discharged through Outfall 001
to the river once or twice per year, historically. In the future
the discharges may be more frequent. In addition, approval has
been given to discharge directly from the new ash pond through
Outfall 001 in order to control the accumulation of selenium in
fish tissue in the cooling pond. In accordance with the permitting
policy for power generating plants, the waste streams to the
cooling pond are treated as separate outfalls with effluent limits
and monitoring requirements. The West and South Retention Basins
receive wastewater from the Oily Waste Treatment System, Low Volume
Waste Sources and yard drains. The Old Ash Pond receives
wastewater from the West and South Retention Basins, Coal Pile and
Tank Farm Runoff, and Chemical Metal Cleaning. The outfall from
the Old Ash Pond to the Cooling Pond is designated Outfall 002.
The discharge from Chemical Metal Cleaning to the Old Ash Pond is
designated Outfall 003. The discharge from the New Ash Pond to the
cooling pond is designated Outfall 004.

When approval was given to discharge from the new ash pond
directly through Outfall 001, some changes were made to the
monitoring requirements. This included more frequent monitoring
for selenium and copper and a requirement for a fish monitoring
study in the Cape Fear River to evaluate the rerouting of effluent
from the Ash Pond. A baseline study has been completed and
submitted and post operation evaluation will be done when direct
discharge begins on a regular basis. The modified outlet structure
from the ash pond allows flow measurements to be made for
discharges to the cooling pond and directly to the river.
The capacity in the ash ponds was becoming critical but ash is
now being removed for use as road base so capacity is now being
restored.
No changes are recommended in the permit structure. The
toxicity monitoring requirements appear to be appropriate and the
facility has had no problem meeting the limits. It is recommended
that a permit be drafted and sent to public notice. If no
significant adverse comments are received, it is recommended that
the permit be reissued for a period of five years.

Sutton Plant's new ash pond is filling up with ash which is causing a lower
residence time within the pond. In an attempt to remedy the situation CP&L
would like to make some changes in 2001 to the route the ash sluice water
takes within the new ash pond (labeled on the attached drawing as the 1984
pond).
First of all, CP&L would like to increase the height of the discharge t) rQISr Om flow
overflow weir of the new ash pond to 30 feet msl. It is currently at 28 / weif
feet msl. The maximum designed operating level of the Ash Pond is 32 feet
msl. The dike crest of the new ash pond is 34 feet msl. After raising the
weir height there will still be 4 feet freeboard.
In addition, a dike internal to the new ash pond (labeled on the attached ` ��)ku� ��
drawing as a floating road) would be constructed of ash material already Z dt
contained within the pond. No modifications would be made to the current Ake"��
dike. This internal dike will be at an elevation of 34 feet msl, the same 1� Nt %oA
elevation as the current dike. Ash sluice water would be routed to this 1
diked area. The internal dike would have a spillway (at 32 feet msl) to
allow water to flow to the rest of the new ash pond for additional settling.
The effluent would discharge (at 30 feet msl) from the new pond to either
the cooling pond or to the Cape Fear River .
The plant currently must physically move the ash sluice lines if they decide
5
to change from adding ash sluice water from the new ash pond to the old ash
f
pond. The plant would like to install additional piping with valves so that
/ j'/
A l�
ash sluice water can be routed to either ash pond with only a couple of
00 Z d'C1D Y
valve manipulations. -r." ' -
P;
At a later date, possibly in 2002, the plant would like to install an
overflow from the new ash pond to the old ash pond (labeled on the attached
3) ow
drawing as the 1983 pond) at an elevation of 28' msl. This would give the
for if
O(.l
/ ��-�Qi
plant the option to use the old pond additional settling needed.
Attached is a rough drawing of what is proposed. Previously in a meeting
with you and Mark McIntire in July 1999 we were told that maintenance
activities such as ash dredging do not need an ATC unless the ash pond is
physically modified, i.e. dikes/berms raised. My questions are:
* Do you concur that the raising of the new ash pond weir to 30 feet
msl is maintenance and does not require an ATC?
* Does the construction of an internal dike require an ATC? If it
does require an ATC, would it make any difference if the elevation of the
internal dike is below the elevation of the current ash pond dike?
* Is an ATC needed for the proposed change in the ash sluice lines?
* Is an ATC needed for the future overflow between the new and old
pond?

Reissuance Application
Dear Mr. Goodrich:
The current NPDES permit for Carolina Power & Light Company's (CP&L) Sutton Steam Electric
Plant located in New Hanover County expires on December 31, 2001. CP&L hereby requests that
the NPDES permit for the facility be reissued. Enclosed are EPA Application Form 1 — General
Information and EPA Application Form 2C — Wastewater Discharge Information, both in triplicate.
The Sutton Steam Electric Plant is expected to continue to operate over the next five years
essentially as it has previously with the exception of the new ash pond discharge (Outfall 004). After
maintenance to the new ash pond in the fall of 2001, it is expected that the new ash pond will
discharge to the Cape Fear River via Outfall 001 on a more routine basis (i.e., several times per
week to daily). When the effluent of the new ash pond is aligned to discharge to Outfall 001, there
will continue to be anywhere from 0 to 0.5 gpm of new ash pond effluent discharging into the cooling
pond. At times that the new ash pond (Outfall 004) is not discharging to the Cape Fear River via
Outfall 001, all of the new ash pond effluent will discharge to the cooling pond.
With reissuance of the NPDES permit, CP&L requests that the requirement to monitor pH for Outfall
001 be reduced from daily to weekly.
If there are any questions regarding the enclosed information, please contact Louise England at
[phone].
Sincerely,
Doug S van

National Pollutant Discharge Elimination System Permit Number NC0001422
Attachment 3
Form 2C - Item 11-B Flow, Sources of Pollution, and Treatment Technologies
The Sutton Plant is a coal-fired steam cycle electric generating plant with three units. Three Internal
Combustion (IC) turbines are also on the plant site. The plant has an 1110 -acre (6,900 acre -ft) off -stream
cooling pond on the east side of the Cape Fear River approximately ten river miles upstream of
Wilmington. Water is withdrawn from the Cape Fear River as required to make up evaporative, seepage,
and blowdown losses from the cooling pond.
Chemical constituents contained in this discharge will, in part, be representative of the naturally occurring
chemical quality and quantity of the intake water and will also have chemical constituents of such quality
associated with similar discharges for fossil generating facilities of this size, type, and in this geographical
location. Either all or part of the elements in the Periodic Table, either singularly or in any combination,
may from time to time be contained in the discharge.
Recirculated Cooling Water
This flow provides condenser cooling water for generating units 1, 2, and 3. The total combined flow of
583 million gallons per day (MGD) is discharged into the pond and routed through the pond by baffle dikes
to achieve maximum surface cooling efficiency before reaching the condenser cooling water intake
structure to be used again. Cooling of the pond is achieved primarily by evaporation from the pond
surface, which is estimated to consume approximately 5.5 MGD above natural evaporation rates during
times the units are in full operation. Control of biological fouling on heat exchanger surfaces is
accomplished by feeding a mixture of bromine and chlorine into the intake structure approximately one
hour once or twice a week with a residual oxidant concentration of 0.2 ppm or less.
Non -contact Cooling Water
Non -contact cooling water is withdrawn from and returned to the cooling pond. It provides indirect cooling
for various plant equipment by absorbing heat as it passes through a heat exchanger. No direct contact is
made with any other equipment or process. Control of biological fouling on heat exchanger surfaces is
accomplished by feeding a mixture of bromine and chlorine approximately one hour per week with a
residual oxidant concentration of 0.2 ppm or less.
Coal Pile Runoff
Stormwater runoff from the coal pile is routed to the old ash pond, which provides neutralization and
sedimentation treatment. During maintenance activities, sludges removed from catch basins, sumps, etc.
may be transported to the old and/or new ash pond for disposal.

Carolina Power & Light Company
L. V. Sutton Steam Electric Plant
National Pollutant Discharge Elimination System Permit Number NC0001422
Storm Water Runoff
Stormwater runoff from the plant area that includes parking lots, switchyard, and the IC Turbine area is
collected in yard drains which flow to the cooling pond. All other yard and plant drains, which may contain
pollutants from spills or leakage from plant processes are routed to one of two retention basins, and
pumped from there to the ash ponds for treatment. During maintenance activities, sludges removed from
catch basins, sumps, etc. may be transported to the old and/or new ash pond for disposal.
Ash Sluice Water
Fly ash and bottom ash from all three units is hydraulically conveyed by an ash sluice pipeline to the
plant's new ash pond, which provides sedimentation and oxidation treatment. Alternatively, fly and
bottom ash may be conveyed to the old ash pond for treatment while maintenance activities are performed
on the new ash pond.
Ash Pond Discharge
Effluent from the new ash pond can be discharged to either the cooling pond or to the Cape Fear River.
When the effluent from the new ash pond is routed to the Cape Fear River, up to approximately 0.5 MGD
will still be discharged to the cooling pond. Effluent from the old ash pond discharges to the cooling pond.
Cooling Pond Discharge
Discharges from the cooling pond to the Cape Fear River have occurred on a sporadic basis. Within the
next permit cycle it is expected to discharge on a more regular basis (e.g., from several times per week to
daily). On an intermittent (e.g., monthly) basis, the blowdown from the cooling pond to the river may reach
approximately 350 MGD for a duration of 1 to 2 days.
Domestic Wastes
Sanitary wastes are treated by an onsite septic tank and drainage field that is permitted by the New
Hanover County Health Department. The septage is exempt from the 40 CFR 503 standards. CP&L will
submit appropriate information to the EPA if required.
All waste streams not identified above fall in the category of low-volume wastes. These wastes include
plant drains, which convey miscellaneous equipment leakage, equipment drainage for maintenance,
equipment washdown water, sampling streams, service water system blowdown, and water treatment
wastes. Plant process water is treated prior to use by an ion -exchange demineralizer which must be
periodically regenerated with solutions of sodium chloride, sodium hydroxide, and sulfuric acid.
Pr

Carolina Power & Light Company
L. V. Sutton Steam Electric Plant
National Pollutant Discharge Elimination System Permit Number NC0001422
Alternatively a vendor may be used to provide treatment of plant process water. Blowdown of boiler water
to control boiler chemistry is routed through low-volume prior to discharge in the ash pond. Boiler
vacuuming sediment is routed through low-volume prior to discharge to the ash ponds. The precipitators
are water washed every 1 to 3 years with the wastewater discharging to the ash pond. Drains from areas
likely to contain oil -filled equipment or storage are routed through an oil -water separator with the effluent
routed through low volume prior to discharge to the ash pond. Waste oil is disposed of according to the
appropriate regulations. During maintenance activities, sludges removed from catch basins, sumps, etc.
may be transported to the old and/or new ash pond for disposal.
All low volume wastes described above are routed by gravity flows to the retention basins at the plant and
then to the ash ponds for treatment by neutralization, sedimentation, oxidation, and absorption.
The air preheaters and electrostatic precipitators are water washed approximately every one to three
years with the wastewater discharging to the ash pond via the ash sluice lines.
In many cases added chemicals are consumed or chemically altered during the plant processes. Only
trace amounts might be recoverable in water entering the ash ponds. Since the ash ponds serve as a
final treatment basin and receives significantly greater volumes of water from other inflows, detectable
levels of these chemicals would not occur in ash pond discharges.
Chemical Metal Cleanina Wastes
The boilers are chemically cleaned every 5 to 10 years using citric acid, ammonium hydroxide, sodium
nitrite, ammonium bicarbonate, and cronox 240, a corrosion inhibitor. In addition the following chemicals
can be used if needed: soda ash, ammonium persulfate, ammonium bifluoride, sodium bromide, and
hydrochloric acid. The cleaning solution and rinses are stored on site for disposal by evaporation in the
boilers. Typical cleanings would result in a waste of approximately 50,000 gallons for Unit 1, 70,000
gallons for Unit 2, 140,000 gallons for Unit 3. Should chemical metal cleaning wastes not be evaporated,
they will be treated by neutralization and precipitation in retention basins prior to discharge to the ash
ponds.
Fire Water System
Several plant heat exchangers are cooled by the fire water system. Control of biological fouling on heat
exchanger surfaces is accomplished by brominating approximately one hour per week with a residual
bromine concentration of 0.2 ppm or less.

Ash Reclamation
In the event a practicable market becomes available, CP&L may exercise the option of reclaiming ash
from it's ash ponds. However, due to the limited scope of such an operation no additional discharges
would be expected.
Old Ash Pond
The old ash pond was listed as a potential Superfund site in the early 1980s during the initial development
of the State Superfund Program. The old ash pond is still listed on the State's Inactive Hazardous Waste
Sites List.
Pesticide Usage in Sutton Cooling Pond
Herbicides are used when needed to control nuisance aquatic vegetation. These herbicides are applied
by licensed applicators, or persons under the immediate supervision of a licensed applicator, in
accordance with the manufacturers instructions.
Piscicides are used when needed to perform biological assessments of fish populations. These piscicides
are applied by licensed applicators, or persons under the immediate supervision of a licensed applicator,
in accordance with the manufacturers instructions.

Fire Department use of Sutton Lake water
Dear Mr. Beck:
Earlier this year Louise England of CP&L contacted Tom Belnick of the NPDES Unit in Raleigh
with a request from the New Hanover County Fire Department (Fire Department) who wished to
use Sutton Lake to withdraw water for maintenance and training. In the event of an emergency
the Fire Department also requested to use water from Sutton Lake for fire fighting purposes. On
December 12, 2000 CP&L was informed via an email message that the following activities are
allowed. CP&L requests a letter documenting that the following activities are allowed:
• The Fire Department will be withdrawing no more than approximately 5000 gallons of
water a year for maintenance and training purposes.
• When performing maintenance and training, the Fire Department shall discharge the
water back into the discharge canal.
• For fire emergency purposes water may be withdrawn from Sutton Lake and the
discharge canal.
Please contact Louise England at [phone] with any questions.
Sincerely,

Fire Department use of Sutton Lake water
Dear Mr. Beck:
Earlier this year Louise England of CP&L contacted Tom Belnick of the NPDES Unit in Raleigh
with a request from the New Hanover County Fire Department (Fire Department) who wished to
use Sutton Lake to withdraw water for maintenance and training. In the event of an emergency
the Fire Department also requested to use water from Sutton Lake for fire fighting purposes. On
December 12, 2000 CP&L was informed via an email message that the following activities are
allowed. CP&L requests a letter documenting that the following activities are allowed:
• The Fire Department will be withdrawing no more than approximately 5000 gallons of
water a year for maintenance and training purposes.
• When performing maintenance and training, the Fire Department shall discharge the
water back into the discharge canal.
• For fire emergency purposes water may be withdrawn from Sutton Lake and the
discharge canal.
Please contact Louise England at [phone] with any questions.
Sincerely,
Dou Sf rivan

As a follow up to a conversation on February 28, 2000, between Mark McIntire of your office
and Louise England of CP&L, the following information is provided regarding Sutton Plant's
routing of ash sluice water to the old ash pond while maintenance is performed on the new ash
pond.
Maintenance must be performed on the discharge pipe from the new ash pond to the cooling
pond (Outfall 004). While maintenance is performed, no water can be released through this
discharge pipe. Sutton Plant proposes to route the ash sluice water from Units 1, 2, & 3 to the
old ash pond while the maintenance is performed. After the maintenance is completed, ash
sluice water will be routed back to the new ash pond. The old ash pond is Outfall 002 in the
current NPDES permit. The monitoring requirements and limits for Outfall 002 are the same as
the monitoring requirements and limits for Outfall 004, the new ash pond.
An amended flow table and Page 3 of 5 of the Description of Wastewater Streams of the NPDES
application are enclosed. By this letter CP&L is seeking your written concurrence that Sutton
Plant may operate in the manner described above.
If you have any questions regarding this information please contact Louise England at (9.19) 362-
3522.

I certify, under penalty of law, that this document and all attachments were prepared
under my direction or supervision in accordance with a system designed to assure that
qualified personnel properly gather and evaluate the information submitted. Based on my
inquiry of the person or persons who manage the system, or those persons directly

Include best management practices to minimize contamination of land or water. With the exception of
coal and ash, practically all material stored outside and which is potentially harmful to stormwater is kept
enclosed or contained to prevent any but accidental contact with precipitation.
Materials stored in bulk are usually in tanks with secondary containment and with valve controlled drains
so that stormwater can be routed to treatment facilities if necessary. Most materials exposed to
stormwater are stored in their original containers in a fenced and paved or graveled storage yard. These
areas of the plant are not easily accessible to vandals or other unauthorized persons. Because of the
active use of these facilities, and their regular inspections, the chances of a significant undetected spill or
leak are minimal. Various brands of commercial herbicides might be used to control weeds and other
unwanted plant growth for security reasons on active industrial areas of the plant, storage areas, and the
plant perimeter. These herbicides are carefully applied by licensed applicators or persons under the
immediate supervision of a licensed applicator, in accordance with the manufacturer's instructions.
Fertilizers are applied only minimally on any of the active industrial areas of the plant. material storage at
the Sutton Plant is as follows. Coal, coal ash, machinery, piping, valves, scrap metal, and structural steel
are stored in open areas. Grease, lubricating oil, herbicides, and detergents are stored in open areas, but
are contained in closed steel or plastic containers. Fuel oil, lubricating oil, and hydrazine are stored in
open areas, usually with secondary containment. Sulfuric acid and sodium hydroxide are stored inside a
building.
Ash Sluice Water
Fly ash and bottom ash from all three units are hydraulically conveyed by an ash sluice pipeline to the
plant's new ash pond, which provides sedimentation and oxidation treatment. The new ash pond has a
remaining usable storage capacity of approximately 822 acre-feet. As shown in the attached worksheet
calculations, the pond has sufficient storage, even during storm events, to provide the required BPT and
BAT levels of treatment for total suspended solids (TSS) and oil and grease (O&G). Therefore, it will not
be necessary to adjust the effluent limits for TSS or O&G to account for dilution from unregulated flows.
Alternatively fly and bottom ash may be conveyed to the old ash pond for treatment while maintenance
activities are performed on the new ash pond.

Louise- I ran this by Ed Beck/Wilmington Region and he is o.k. with this
incidental water use, as long as the water is taken from the discharge
canal/lake and not the ash pond. You don't need any permit from us to do
this.

Hi Tom
If the fire dept wants to take water from Sutton Lake for training
purposes and return it to the lake, which then discharges through the
permitted outfall, this should be ok. This would be better than
introducing it at the point of discharge to the river. As far as using
water from the lake for fire fighting off site, the water is clean
enough to support a healthy population of bass and other fish so it
should be ok. The one constituent of concern recently, selenium, has
been based on bioaccumulation in fish tissue, which is not a problem now
that they are discharging at a more frequent rate.
I don't see a problem with this incidental use as long as it is taken
from the lake and not the ash pond.

Permit NC0001422
Sutton Steam Electric Plant
New Hanover County
Dear Mr. Miller:
The Division is beginning the cycle of permit renewals for the Cape Fear river basin. An examination of the Cape
Fear basin plan and the NPDES permit schedule has revealed that the existing expiration dates in Cape Fear NPDES
permits do not coincide with the revised permit expiration dates for the basin. This discrepancy could create unnecessary
delays in the processing of over 200 permit renewals. Accordingly, the Division is changing the permit expiration dates for
NPDES permits in the Cape Fear river basin.
This permit modification changes the expiration date of the subject permit in subbasin 30617 to December 31, 2001.
Please find enclosed the revised permit cover page. Insert the new cover page into your permit and discard the old page.
All other terms and conditions contained in the original permit remain unchanged and in full effect. This permit
modification is issued under the requirements of North Carolina General Statutes 143-215.1 and the Memorandum of
Agreement between North Carolina and the U. S. Environmental Protection Agency.
In accordance with the modification of the permit expiration date, the new due date for your renewal application is
July 4, 2001. Renewal application forms will be sent to you approximately 6-8 weeks in advance of the new due date or
you may download the forms from the NPDES web site at http://h2o.enr.state.nc.us/NPDES/documents.html. You
will need to download Standard Form C. If you have already submitted a permit renewal form, there is no need to
submit any other forms to the Division; the application will be processed during the renewal period for your subbasin.
If any part of this permit modification are unacceptable to you, you have the right to an adjudicatory hearing upon
written request within thirty (30) days following receipt of this letter. This request must be a written petition conforming
to Chapter 150B of the North Carolina General Statutes, filed with the Office of Administrative Hearings (6714 Mail
Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning this permit modification, please contact Natalie Sierra at [phone],

Louise- hope the following helps:
NC0001422 (Sutton Steam). It sounds fine to sample from the cooling pond just upstream of the discharge
point.
NC0003433 (Cape Fear). If you just summarize what was collected over the last permit round, this should
suffice for the permit renewal.

Cape Fear Plant is also preparing to sample for their permit renewal. The
last discharge from outfall 008 (stormwater from the abandoned ash pond) was
in April of 1998. Plant staff do not expect to receive rainfall sufficient
to produce a discharge from this outfall so we will be unable to include

As a follow up to a conversation on February 28, 2000, between Marls McIntire of your office
and Louise England of CP&L, the following information is provided regarding Sutton Plant's
routing of ash sluice water to the old ash pond while maintenance is performed on the new ash
pond.
Maintenance must he performed on the discharge pipe from the new ash pond to the cooling
pond (Outfall 004). While maintenance is performed, no water can be released through this
discharge pipe. Sutton Plant proposes to route the ash sluice water from Units 1, 2, & 3 to the
old ash pond while the maintenance is performed. Ager the maintenance is completed, ash
sluice water will be routed back to the new ash pond. The old ash pond is Outfall 002 in the
current NPDES permit. The monitoring requirements and limits for Outfall002 are the same as
the monitoring requirements and limits for Outfall 004, the new ash pond.
An amended flow table and Page 3 of 5 of the Description of Wastewater Streams of the NPDES
application are enclosed. By this letter CP&L is seeking your written concurrence that Sutton
Plant may operate in the mariner described above.
If you have any questions regarding this information please contact Louise England at (919) 362-

Jacksonville area this year when low flows caused salinity changes and the
fish weren't there. Mark seemed to think this wouldn't be a problem in data
analysis. As for QA/QC-I'll check on what we've required as far as
contracting labs -not sure.

CP&L• Sutton Steam; NPDES No. NC0001422
Subject: CP&L Sutton Steam; NPDES No. NC0001422
Date: Tue, 24 Nov 1998 15:02:37 -0500
From: Tom Belnick <tom [e-mail]>
To: Fred holt <[e-mail]>
Fred- Based on the conversation between Dave Goodrich and myself, DWQ
offers the following information in regard to the subject permit. The
permit was modified by transmittal letter dated October 19, 1998. Item
#2 on the modified Supplement to Permit Cover Sheet page contained flow
language which describes the proposed effluent pipe routing system,
based on information provided by CP&L. DWQ interprets this language as
descriptive in nature and does not necessarily impose flow restrictions
on the routing of ash pond effluent to outfall 001. Due to the
uncertainty in projected flow from 004 (now estimated at 3-3.25 MGD
monthly average), DWQ feels that CP&L should operate the ash pond
routing system as is currently designed. After actual flow data is
collected, DWQ may modify the permit if flow restrictions are deemed
necessary to protect water quality.
