Subject: Modification of NPDES Permit No. NC0004774
Buck Steam Station
Rowan County
The Division is beginning the second five-year cycle of river basin planning and permit renewals. An
examination of the basin planning schedule has revealed that the timing of permit renewals does not
allow an evenly distributed workload as first envisioned. This results in problems with the efficiency
and effectiveness of the NPDES program. In an effort improve customer service, and after thorough
review of the water quality issues in your area, the Division is changing the permit renewal schedule for
all NPDES permits in your sub -basin.
This permit modification changes the expiration date of the subject permit to June 30, 1999. 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 pursuant to 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.
If you helve already submitted a permit renewal application for the subject facility, the Division will
retain the application until your permit is due for renewal. No additional forms or fees will be required.
If any parts, measurement frequencies or sampling requirements contained in 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,
Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this
decision shall be final and binding.
If you have questions about this modification, please contact Charles Weaver of my staff at the
telephone number or address listed below.

Subject: Status of NPDES Permit NC0004774
Rowan County
After a thorough review of the Yadkin -Pee Dee River basin management plan and water quality issues relevant to
the subject facility, the Division of Water Quality has decided to extend the duration of the subject permit. The
expiration date of your permit will be changed in order to allow the Division to review all NPDES discharge
permits in the Yadkin River Basin during calendar year 1999.
All terms and conditions in the existing permit will apply until a new expiration date is assigned by the Division.
Extension of existing Effluent Limitations and Monitoring Requirements does not exempt the subject facility from
the new Enforcement Policy recently enacted by the Division.
Attached to this letter is a copy of the Public Notice that is being published to announce the planned extension of
your permit. After Public Notice has been made by the Division, the expiration date of your permit will be
changed via a permit modification. No draft permit will be sent out with the Public Notice, as none of the
conditions in the existing permit will be modified.
The Division appreciates your patience and understanding to date regarding the rescheduling of the subject
permit. If you have already submitted your renewal application package, no additional fees or documentation will
be required as a result of this change to your permit's expiration date.
If you have questions about this proposed modification or about the permit renewal process, contact Charles
Weaver of my staff at the telephone number or address listed below.

Subject: Downstream Temperature Monitoring
Buck Steam Station
NPDES Permit Number NC0004774
Rowan County
Over the past several months, Mark McIntire has worked with Ron Lewis of your office
regarding the possibility of eliminating the downstream monitoring requirement for temperature in
lieu of sampling by the Yadkin -Pee Dee Sampling Coalition. A review of the current sampling location
and possible future locations has indicated that continued sampling is neither convenient nor practical.
Furthermore, in light of the body of temperature data collected to date and the balanced and
indigenous population study conducted annually, continued downstream temperature monitoring does
not provide critical water quality information for High Rock Lake.
Attached with this letter is an amended effluent page A(1). This page should be inserted into
your permit and the old one discarded. This permit modification is issued pursuant to the
requirements of North Carolina General Statute 145-215.1 and the Memorandum of Agreement
between North Carolina and the U. S. Environmental Protection Agency dated December 6, 1983.
Please take notice that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge. This permit
does not affect the legal requirement to obtain other permits which may be required by the Division of
Water Quality or permits required by the Division of Land Resources, Coastal Area Management Act
or any other Federal or Local government permit that may be required.
If you have any questions or comments regarding these speculative limitations, please do not
hesitate to contact Mark McIntire at telephone number [phone], extension 553.

I am responding to your letter of September 3, 1993 in reference to the modification of
the domestic sewage treatment system -at the Buck Steam Station. Based on information
gathered by the Division, the background level for BOD is set at 1.5 mg/1 for nature background
levels. We are forwarding herewith the corrected effluent pages with reference to a allowable
background level of BOD of 1.5 mg/l. The effluent page for once through cooling water has not
been modifided.
Please find enclosed new effluent pages for the ash settling pond discharge. The old
pages should be discarded. All other terms and conditions contained in the original permit
remain unchanged and in full effect. These permit modifications are issued pursuant to 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.
If any parts, measurement frequencies or sampling requirements contained in 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 in the form of
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed

Duke Power Company -Buck Steam Station
NPDES Permit No. NC0004774/002

- By cover letter dated July 29, 1994, the facility was issued NPDES Permit No.
NC0004774 with an effective date of September 1, 1994, and expiration date of July 31,
1998. Upon review of the toxicity language contained in the permit, it was noted that the
permit does not reflect the new permitting strategy, effective October 1991, which
eliminates all references to two consecutive toxicity tests. Under Part III, Condition O, the
following language is present - "The LC50 of this effluent using the previously stated
methodology may at no time in any two consecutive toxicity tests be less than 60%." Part
III, Condition O also indicates a the sampling type for toxicity to be 24 hour grab sampling.
This office recommends modification of the permit to incorporate language in Part III,
Condition O to read, "The LC50 of this effluent using the previously stated methodology
may at no time in any toxicity test be less than 60%." We also recommend that the toxicity
sampling language be changed to reflect a grab sample.
I appreciate your assistance to review the recommended changes and undertake any
necessary steps to modify the existing permit. Should you have any questions, please feel
free to contact me at 2136.

Dear Mr. Carter:
Our records indicate that NPDES Permit No. NC0004774 was
issued on July 29, 1994 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 are Pages 4-5.
Pages 4-5 set forth the effluent limitations and monitoring
requirements for your discharge (s). Your discharge(s) 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 the
reporting forms furnished to you 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 (DEM Form MR-1), plus instructions for completing the form.
It is imperative that all applicable parts be completed, and the
original and one copy be submitted as required.
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 operator if you are operating wastewater treatment

facilities. Any changes in operation of wastewater treatment
facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment
facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $10,000 per violation plus criminal penalties may
be assessed for such violations. If you find at any time that you
are unable to comply with the terms and conditions of the Permit,
you should contact this Office immediately. A Consent Order may be
necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a
five-year period. Permits are not automatically renewed. Renewal
requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of
your Permit. This date is set forth on Page 1 of the Permit. Also
note that NPDES Permits are not transferable. If you, as the
Permittee, cease to need this Permit, then you should request that
the Permit be rescinded.
As mentioned previously, the purpose of this letter is to
advise you of the importance of your NPDES Permit. Please read the
Permit and contact this Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to
providing any assistance.

ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Daphnid 48 hr - LC50
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 6,00/4-85/0 i 3 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms". The monitoring shall be performed as a Daphnia up lex or
Ceriodaphnia 48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any two consecutive toxicity
tests be less than(LQ %. Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The first test will be performed a ter
thirty days from issuance of this permit during the months of ffbr fun (5cp De -(-
The parameter code for this test if using Daphnia pulex is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. All toxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in
which it was performed, using the appropriate parameter code. Additionally, DEM Form AT-1
(original) is to be sent to the following address:
Attention: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include allsupporting chenucal/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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management 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 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.

On January 20, 1993 the Division of Environmental Management received a request from
Dayna Russell of Duke Power for the reduction in monitoring requirements. The requirement
requested to be removed from the above mentioned permits read as follows: "One additional grab
sample shall be collected and analyzed for oil and grease, and total suspended solids during the
period of maximum expected flow for each rainfall event exceeding a specified depth per facility
per day (25% of the 1 OY24H event). The corresponding flow shall be reported. The Permittee
shall report the presence of cenospheres observed in the samples. After monitoring for a period
of one year, the Permittee may request reduction or elimination of this monitoring." DEM has
reviewed the request and the data submitted over the past year for the above facilities and has
agreed to the reduction of monitoring by removing the above statement.
Please find enclosed revised effluent pages which should be inserted into each appropriate
permit. The old pages should be discarded. The effluent pages for Marshall (NC0004987) have
previously been changed and sent under separate cover. All other terms and conditions contained
in the original permit remain unchanged and in full effect. These permit modifications are
issued pursuant to 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.
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

Supplemental Information
for
-Buck Steam Station
Date: 1/89

Buck Steam Station utilizes water drawn from the Yadkin River at the upstream
end of High Rock Lake. After various usages and treatments, the plant
effluents discharge back into High Rock Lake. A schematic flow diagram of
water use, treatment and discharge is attached. The following discussion
refers to that diagram.
1. Boiler Blowdown: Blowdowns from boiler 8 and 9 (units 5 and 6) discharge
steam to the atmosphere at an average rate of 1,500 LB/HR each for a
total of 9,000 GPD. Boilers 5, 6 and 7 (Units 3 and 4) collectively
discharge a total blowdown of 3,000 LB/HR or 9,000 GPD to the waste water
sump then to the ash basin. All floor drains associated with retired
units 1 and 2 (boilers 1-4) are consolidated into the waste water sump
and pumped to the ash basin.
2. Floor Drains: Floor drains collect plant water treatment equipment
wastes and miscellaneous equipment cooling water. This water is routed
to the ash basin. Approximately 2_1 MGD of uncontaminated cooling water
is discharged through a series of approximately 20 individual powerhouse
drains to the river.
3. Chemical Cleaning of Boilers: Boilers 8 and 9 are chemically cleaned
every three years. No other boilers are cleaned chemically. Normally
the cleanings are scheduled for different years. Approximately 266,000
gallons of water and chemicals are used per, boiler for each chemical
cleaning job. Chemicals and amounts used per cleaning are listed below.
The waste solution is discharged to the ash basin along with the normal
ash sluicing flow to the drain. Immediately prior to the beginning of a
boiler chemical cleaning procedure, additional blocks are added to the
ash basin discharge structure. This assures longer retention time of the
chemical wastes for proper treatment through dilution, neutralization,
precipitation, and ion exchange as documented in the Ash Basin Equivalen-
cy Demonstration (October 1976).
Chemicals Amounts
Sodium Bromate
550 lbs.
Ammonium Carbonate
1,000 lbs.
Ammonium Hydroxide (26°Be)
850 gals.
Hydrochloric Acid (31.5%)
3,300 gals.
Copper Complexer
1,620 lbs.
Ammonium Bifluoride
1,000 lbs.
Sodium Carbonate
2,000 lbs.
Citric Acid
200 lbs.
4. Coal Yard Drainage: The coal yard drainage at Buck Steam Station drains
to the waste water sump and is then pumped to the ash basin. The coal
yard watershed area is approximately 12.34 acres. The coal yard has an
average run-off of 0.018 MGD. The run-off is based on 40 inches of rain
per year with 50% run-off.
5. Ash Basin Overflow: The ash basin at Plant Buck accommodates flows from
the waste water sump, ash removal lines and rainfall run-off from the
basin watershed area. The average rainfall run-off flows are based on
forty inches of rain per year with fifty percent run-off. The average
BK-PAGE 2

rainfall for the ash basin watershed area is 0.328 MGD. The average flow
from the waste water sump is 1.274 MGD. The daily ash removal flow is
2.640 MGD. These flows give a total influent flow to the basin of 4.242
MGD.
Due to the construction of the outfall structure, the effluent flow to
the basin is essentially equal to the influent flow (refer to the at-
tached schematic of water flow for further information of individual
flows to the ash basin).
6. Oil Storage Run -Off: Buck Steam Station has one large fuel oil storage
tank 3,000,000 gals.). This tank is surrounded by a dike capable of
containing the entire capacity of the tank in the event of an accidental
rupture. The diked area is drained of uncontaminated rainwater through a
manually operated siphon device.
All oil storage facilities are presently covered under Spill Prevention
and Countermeasure Plans.
7. Intake Screen Backwash: Intake screens are backwashed at a rate of
255,000 GPD with untreated river water. The solid material washed from
the screens is collected by a trough and returned to the lake below a
retaining wall. downstream from the plant intake. The debris collected on
the screens consist mainly of twigs, leaves, and other materials indige-
nous to the river and is therefore returned to the river without any
adverse environmental impact.
8. Water Treatment Wastes: The water treatment wastes at Buck Steam Station
consists of:
a. Sedimentation wastes,
b. Filter backwash and
C. Demineralizer regeneration wastes.
Polymer (Nalco 8105) and clay (Calgon CA-25) are used to effect precipi-
tation and thus remove suspended solids from the raw river water. This
precipitate is discharged to the floor drain along with approximately 340
GPD of water which flows to the unit 5 and 6 pump room sump.
Filter backwash consists of wash water from the clarification filters and
wash water from the carbon filters which immediately precede the
demineralizer. Approximately 4,000 GPD of wash water is used for clari-
fication equipment backwash and 1,700 GPD for carbon filter backwash.
Both of these flows are discharged to the floor drains and flow to the
pump room sumps.
The station is equipped with one demineralizer consisting of two mixed
bed cells. Each cell is regenerated approximately twice each week. Each
regeneration requires 20 gallons of 66 Be sulfuric acid and 94 gallons of
50% sodium hydroxide. Each of these chemicals is diluted to approximate-
ly a 4% solution before being fed into the cell. The acid and caustic
are fed into the cell simultaneously and substantially neutralize each
other upon discharge. Approximately 14,000 gallons of water is used per
regeneration which further dilutes the neutralized chemicals. This flow
BK-PAGE 3

is discharged to the pump room floor drain and flows into the sump. all
of the water treatment wastes total approximately 14,000 GPD. The
wastewater is discharged to the pump room sumps and pumped to the ash
basin.
9. Effluents from Air Pollution Control Devices: Electrostatic precipita-
tors are used for the control of air pollution at Buck Steam Station.
The collected fly ash is sluiced to the ash settling basin as discussed
in Item 5.
10. Sanitary Wastes: Approximately 200 people per day contribute to the
sanitary waste at the station. Assuming 30 gallons per person per eight
hour shift, 6,000 gallons of domestic wastes are treated each day in the
septic tank - sand filter system. The total 6,000 GPD flow is discharged
to the ash pit and then to the ash basin.
11. Condenser Cooling Water: Condenser cleaning is accomplished mechanical-
ly. After the condenser is drained, loose solid material is blown from
the tubes with compressed air. Mud and slime are removed by forcing
rubber plugs through the tubes.
Condensers for Units 3, 4, 5 and 6 are each equipped with two condenser'
circulating (CCW) pumps (units 1 and 2 retired). The capacities of these
pumps are listed below. The operational schedule for these pumps is
dependent on the inlet temperature and on the unit load.

5. ',N1ws`Dav Mewurements
a. The "month]%- 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 arithmetic7 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 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
floe 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 1.
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.

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.

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

(1) Five hundred micrograms per liter (500 ug/1);
(2) One milligram per liter (1 mg/1) for antimony;
(3) Ten (10) times the maximum concentration value reported for that pollutant in the
permit application.
D. RRe uirement to Continually Evaluate Alternatives to Wastewater Discharges
The permittee shall continually evaluate all wastewater disposal alternatives and pursue the
most environmentally sound alternative of the reasonably cost effective alternatives. If the
facility is in substantial non-compliance with the terms and conditions of the NPDES permit
or governing rules, regulations or laws, the permittee shall submit a report in such form and
detail as required by the Division evaluating these alternatives and a plan of action within
sixty (60) days of notification by the Division.

E. Toxicity Reopener Condition
This permit shall be modified, or revoked and reissued to incorporate toxicity limitations
and monitoring requirements in the event toxicity testing or other studies conducted on
the effluent or receiving stream indicate that detrimental effects may be expected in the
receiving stream as a result of this discharge.
F. If the Permittee, after monitoring for at least six months, determines that he is
consistently meeting the effluent limits contained herein, the permittee may request of the
Director that the monitoring requirements be reduced to a lesser frequency.
G. There shall be no discharge of polychlorinated byphenyl compounds such as those
commonly used for transformer fluid.
H. Biocide Condition
The permittee shall not use any biocides except those approved in conjunction with the
permit application. The permittee shall notify the Director in writing not later than ninety
(90) days prior to instituting use of any additional biocide used in cooling .systems which
may be toxic to aquatic life other than those, previously reported to the Division of
Environmental Management. Such notification shall include completion of Biocide
Worksheet Form 101 and a map locating the discharge point and receiving stream.
I. Continued intake screen backwash discharge and non -contact cooling water (outfall
003) discharges are permitted without limitations or monitoring requirements.
J. Nothing contained in this permit shall be construed as a waiver by permittee or any
right to a hearing it may have pursuant to. State or Federal laws or regulations.
K. The term "low volume waste sources" means, taken collectively as if from one source,
wastewater from all sources except those for which specific limitations are otherwise
established in this part. Low volume wastes sources include, but are not limited to:
Wastewater from wet scrubber air pollution control systems, ion exchange water
treatment system, water treatment evaporator blowdown, laboratory and sampling
streams, boiler blowdown, floor drains, cooling tower basin cleaning wastes, and
recirculating house service water systems. Sanitary and air conditioning wastes are not
included.
L. The term "metal cleaning waste" means any wastewater resulting from cleaning (with
or without chemical cleaning compounds) any metal process equipment including, but
not limited to, boiler tube cleaning, boiler fireside cleaning, and air preheater cleaning.
Metals cleaning will be conducted according to Duke Power's -approved equivalency.
demonstration.
M. The term, "chemical metals cleaning waste" means any wastewater resulting from the
cleaning of any metal process equipment with- chemical compounds, including, but not
limited to, boiler tube cleaning.
N. It has been determined from information submitted that the plans and procedures in
place at Buck Steam Station are equivalent to that of a BMP.

O. ACUTE TOXICITY PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterly 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
Daphnia pulex or Ceriodaphnia 48 hour static test, using effluent collected as a 24 hour
grab. The LC50 of this effluent using the previously stated methodology may at no time
in any two consecutive toxicity tests, be less than 60%. Effluent samples for self -
monitoring purposes must be obtained during representative effluent discharge below all
waste treatment. The first test will be performed after thirty days from the effective date
of this permit during the months of March, June, September and December.
The parameter code for this test if using Daphnia pulex is TAA3D. The parameter code
for this test if using Ceriodaphnia is TAA3B. All toxicity testing results required as part
of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-
1) for the month in which it was performed, using the appropriate parameter code.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 reedy Creek Road
Raleigh, N.C. 27607
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 any single quarterly monitoring indicate a failure to meet specified limits, then
monthly monitoring will begin immediately until such time that a single test is passed.
Upon passing, this monthly test requirement will revert to quarterly in the months
specified above.
Should any test data from either these monitoring requirements or tests performed by the
North Carolina Division of Environmental Management 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 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.
P. Discharge of any product registered under the Federal Insecticide, Fungicide, and
Rodenticide Act to any waste stream which may ultimately be released to lakes, rivers,
streams or other waters of the United States is prohibited unless specifically authorized
elsewhere in this permit. Discharge of chlorine from the use of chlorine gas, sodium
hypochlorite, or other similar chlorination compounds for disinfection in plant potable
and service water systems and in sewage treatment is authorized. Use of restricted use
pesticides for lake management purposes by applicators licensed by the N.C. Pesticide
Board is allowed.

Q. Pollutant Analysis Condition
The permittee shall conduct a test for pollutants annually at the effluent from the
treatment plant. The discharge shall be evaluated as follows: 1) A pollutant analysis of
the effluent must be completed annually using EPA approved methods for the following
analytic fractions: (a) purgeables (i.e., volatile organic compounds);. (b) acid extractables;
(c) base/neutral extractables; (d) organochlorine pesticides and PCB's (e) herbicides; and
(f) metals and other inorganics. The Annual Pollutant Analysis Monitoring (APAM)
Requirement Reporting Form A and accompanying memo, to be provided to all
discharges affected by this monitoring requirement, describes the sampling and analysis
requirements and lists chemicals to be included in the pollutant analysis. This monitoring
requirement is to be referred to as the "Annual Pollutant Analysis Monitoring
Requirement" (APAM).
(2) Other significant levels of organic chemicals must be identified and approximately
quantified. For the purpose of implementing this requirement, the largest 10 GC/MS
peaks in the purgeable base/neutral extractable, and acid extractable fractions (or fewer
than 10, if less than 10 unidentified peaks occur) for chemicals other than those specified
on the APA Requirement Reporting Form A should be identified and approximately
quantified as stated in the APAM Reporting Form A instructions. This part (item 2) of
the APAM requirement is to be referred to as the "10 significant peaks rule").
R. Beginning on the effective date of this permit and lasting until expiration, there shall
be no discharge of plants wastes to the ash pond unless the permittee provides and
maintains at all times a minimum free water volume (between the top of the sediment
level and the minimum discharge elevation) equivalent to the sum of the maximum 24-
hour plant discharges plus all direct rainfall and all runoff flows to the pond resulting
from a 10-year, 24-hour rainfall event, when using a runoff coefficient of 1.0. During the
term of the permit, the permittee shall remove settled material from the ponds or
otherwise enlarge the available storage capacities in order to maintain the required
minimum volumes at all times. No later that December 31, 1989, and annually thereafter,
the permittee shall determine and report to the permit issuing authority: (1) the actual free
water volume of the ash pond, (2) physical measurements of the dimensions of the free
water volume in sufficient detail to allow validation of the calculated volume, and (3) a
certification that the required volume is available with adequate safety factor to include
all solids expected to be deposited in the ponds fro the following year. Present
information indicates a needed volume of 186.3 A-ft in addition to solids which will be
deposited in the ash pond. Any changes to plant operations affecting such certification
shall be reported to the Director within five days.
NOTE: In the event that adequate volume has been certified to exist for the term of the
permit, periodic certification is not needed.
S. It has been demonstrated that under certain conditions it is possible to reduce the
concentration of metals in boiler cleaning wastes in the range of 92 to 99+ percent by
treatment in ash ponds. Because of dilution problems, and the existence of boundary
interface layers at the extremities of the plume, it is difficult to prove beyond doubt that
the quantity of iron and copper discharged will always be less than one milligram per liter
times the flow of metal cleaning when treated in this manner.
The application of physical/chemical methods of treating wastes has also been
demonstrated to be effective in the treatment of metal cleaning wastes. However, the

effectiveness of ash pond treatment should be considered in relation to the small
differences in effluent quality realized between the two methods.
It has been demonstrated the presence of ions of copper, iron, nickel, and zinc in the ash
pond waters was not measurably increased during the ash pond equivalency
demonstration at the Duke Power Company's Riverbend Steam Station. Therefore, when
the following conditions are implemented during metal cleaning procedures, effective
treatment for metals can be obtained at this facility:
1. Large ash basin providing potential reaction volumes in the ratio of 100 to 1.
2. Well-defined shallow ash delta near the ash basin influent.
3. Ash pond pH of no less than 6.5 prior to metal cleaning waste addition.
4. Four days retention time in ash pond with effluent stopped.
5. Boiler volume less than 86,000 gallons.
6. Chemicals for cleaning to include only one or more of the following:
a. Copper removal step- sodium bromate, NaBrO; ammonium carbonate,
(NH)CO; and ammonium hydroxide, NHOH.
b. Iron removal step -hydrochloric acid, HCl; and ammonium bifluoride, (NH)BF
and proprietary inhibitors.
7. Maximum dilution of wastes before entering ash pond 6 to 1.
8. After treatment of metal cleaning wastes, if monitoring of basin effluents as required
by the permit reveals discharges outside the limits of the permit. permittee will re -clone
the basin discharge, conduct such in -basin sampling as necessary to determine the cause
of nonconformance, will take appropriate corrective actions, and will file a report with
EPA including all pertinent data.
T. The Permittee shall report all visible discharges of floating materials, such as, an oil
sheen to the Director when submitting DMR's.
U. The permittee shall check the diked areas for leaks by a visible inspection and shall
report any seepage detected.

PART IV
ANNUAL ADMINISTERR,vG AND COMPLLANCE MONITOR�TG FEE RE QUIRENiENTS
A. The permittee must pay the annual administering and compliance monitoring fee within 30
(thirty) days after being billed by the Division. Failure to pay the fee in a timely manner in
accordance with 15A NCAC 2H .0105(b)(4) may cause this Division to initiate action to
revoke the permit.

Dear Mr. Hammond:
The Division of Environmental Management (DEM) has reviewed your letter of August
23, 1991, concerning the monitoring procedure at the downstream monitoring site for Buck
Steam Station. This letter is issued to modify the downstream monitoring requirements as
follows. Downstream monitoring for the station shall occur at the existing monitoring site and
shall be recorded at three foot intervals starting at one foot below the surface and ending at 40
feet below the surface. Duke Power shall report the average of the fourteen temperature
readings on its Discharge Monitoring Report to determine compliance with the permit limitations.
The DEM requests that the individual readings be kept on file for future review. This could be
beneficial information for future studies of the lake.
In the interim period prior to installation and operation of the new equipment, Duke
Power Company may elect to continue to monitor at its existing location one foot below the surface
for compliance purposes. The only other monitoring option that the DEM will agree with during
this interim period is to manually monitor the temperature down to 40 feet. This monitoring
shall consist of recording temperatures at three foot intervals starting at one foot below the
surface and ending at 40 feet below the surface. Duke Power shall report the average of the
fourteen temperature readings on its Discharge Monitoring Report to determine compliance with
the permit limitations. Duke Power shall specify whether each entry on the Discharge
Monitoring Report is the result of one reading at one foot below the surface or if it is the result of
an average of the fourteen readings.

Dear Mr. Parker:
Our records indicate that NPDES Permit No. NC 0004774 was
issued on December 7, 1989 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 M3.
Page M3 sets forth the effluent limitations and monitoring
requirements for your discharge(s). Your discharge(s) must not
exceed any of the limitations set forth. The section headed
r
"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 the
reporting forms furnished to you by this Agency. If you have not
received these forms, they should be arriving shortly. If you
fail to receive the form, please contact this Office as quickly
as possible. I have enclosed a sample of the "Effluent"
reporting form (DEM Form MR-1), plus instructions for completing
the form. It is imperative that all applicable parts be
completed, and the original and one copy be submitted as
required.
The remaining Parts of the Permit (Parts II and III) set
forth definitions, general conditions and special conditions
applicable to the operation of wastewater treatment facilitie.s
and/or discharge(s). The conditions include special reporting

Sanitary Sand Filter Bypass
File: BK-704.15
Certified: P-068-518-878
Dear Ms. Sullins:
We would like to request permission to modify the sanitary waste treatment
process at Huck Steam Station. Currently, sanitary waste flows through a septic
tank to a sand filter and is then pumped to the ash basin prior to discharge through
outfall 002.
In order to reduce the amount of solids and sand that is sent to a land disposal
unit, we would like to bypass the sand filter and route the septic tank effluent
directly to the ash basin (see attached drawing for piping changes). The ash basin
has, be=.^ shown to effectively treat sanitary waste both in the laboratory and in
practice. The attached study, by Duke Power Company, shows significant
reduction in BOD5 a-"d fecal coliforrn after mixing with flyash (see attached`
report).
The ash basin has a volume of approximately 337 Mgal providing significant
dilution and a retention time of '28 days to allow secondary stage settling. The
maximum flow from the septic tank is .006 MGD, while the total flow from the
basin is 1.7 million gallons per day.
Your prompt attention to this matter is appreciated. Should you have any
questions or require additional information, please contact me at [phone].

MEMORANDUM TO FILE
Subject: Flyash Treatment of Sanitary Wastewaters
Files: GS-216.04, 702.12
As part of the documentation.for use in our current round of NPDES permit
renewals, the System Power Chemistry Unit conducted an ash basin equiva-
lency study to verify the treatability of partially treated domestic
wastewaters with flyash. Since it would be impractical to determine the
treatment capability of the ash basin for partially treated sanitary wastes
within .the ash basin, a literature citation and results of a laboratory
bench study will be presented.
Our review of the literature has revealed no direct application for utilizing
operating ash basins as a means to treat sanitary waste. However, available
literature citations indicate the chemical and physical properties of flyash
are capable of providing treatment of raw sanitary wastes.
Tenney and Echelbergerx have documented the use of flyash for the treatment
and renovation,of various polluted waters. They report certain properties
and characteristics of flyash make this material useful in the treatment of
eutrophic lakes, sewage plant sludge, and acid mine wastes containing
excessive quantities of acid and soluble iron. Clark and Othmer2 have also
noted flyash'obtained from electrostatic precipitators can be used in water
treatment processes. Flyash can increase the rate of floc growth, enhance
floc settling properties, precipitate phosphates and absorb organic molecules
from waste waters. Tossey, Fleming and Scott have shown lime, alum, silica,
ferric sulfate - major constituents in flyash - significantly reduce suspended
solids, BOD, and phosphates in a secondary -treated effluent. Alumina and .
carbon, the other major flyash constituents not studied by Tossey et.. al., are
also routinely used for separating and isolating organic molecules.
The combined treatment capabilities. of the constituents of flyash will treat
domestic waste waters to permit limits within the ash basin. The retention
time within the ash basin provides for clarification of suspended solids
associated with sanitary wastes and other waste streams. Removal of fecal
organisms is accomplished by sorption on flyash particulates. Even though.
the literature does not report a kill of the fecal organisms,, treatment and
disposal of these pollutants is accomplished as a result of fresh ash
covering over the ash previously used for -treatment.
The results of bench studies confirm the treatment capabilities of flyash
when treating sanitary wastes: .

within an active ash basin should be attainable from regulatory agencies.
