monitoring on the DMRs they submit.
Per a memo from Duke Power to Cal Sullins dated April 9, 1996, Duke Power plans to
separate the industrial and domestic waste streams. The TTC's industrial wastewaters will, be
routed to McGuire's outfall, 002 (NCO024392). The domestic wastewater will be routed to
McGuire's outfall 003. By the end of 1996 rerouting of the wastewater is scheduled to be
completed and all of the TTC's discharges (001,002,003, and 004) will be eliminated.

,G.
The facility failed its acute tonicity test twice in 1994. Since then the facility has
consistently passed. high effluent chlorine concentrations repo md in the DMRs may have been
responsible for the toxicity test failures. The facility has been compliant with their other permit
limits. Mercury concentrations above a detection level of 0.1 ug1L, have been measured ure since the
last permitrenewal in 1993. A mercurylimit continues to be recommended given that Lake
Norman an is heavily used for primary recreation and fishing.
A. Ceriodaphnia toxicity test continues to be recommended as opposed to the standard
fathead minnow test, Duke Power has a certified ;lab for Cerios but not for fatheads. Since the
C:erio test is considered more restrictive this deviation from the standard tox test is considered
acceptable.

This Wf,A is for outfall 003.
According to Norma Atherton. (70 -875-5 u3), a
Duke Power representative, outfall 003
has been capped and is no longer discharging. This discharge originated from fish tanks and/or
from an aquatics laboratory which is no longer in use. The latest staff report dated March 8, 199
does not mention that this outfall has'been upped so it is
recommended that the region confmn the
status of outfall 003.

Dear Mr. Carter:
In accordance with your application for discharge permit received can January 1, 1995, we are
forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to the requirements
of North Carolina General Statute 43-21 .1 and the Memorandum of Agreement between North Carolina
d the US Environmental Protection agency dated December 6, 1953
If any parts, measurement frequencies or sampling requirements contained in this permit are
acceptable 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, Post Office Drawer 27447, Raleigh, North Carolina 27611 -7447. Unless such demand i
de, this decision shall be `final and binding.
Please take notice this permit is not transferable. Part 11, EA addresses the requirements to be
followed in case of change in ownership or control of this discharge. Also note that this permit is
scheduled to expire in December 1996. This expiration elate is not in synch with the Catawba River Basin
Plan, which would require a five year permit term, However, Duke Power intends to eliminate this
discharge by August of 1995, so the current expiration date is in keeping with removal of the discharge.
This perinit does not affect the legal; requirements to obtain other permits which may be required by
the Division of Environmental Management or permits required by the Division of Land Resources,
Coastal Area Management Act or any other Federal or Local governmental permit thatmay be required.
If you have any questions concerning this permit, please contact Jeanette Powell at telephone number

G. ACUTE TOXICITY PASS/FA11L PERMIT LIN41T (QR
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining :Acute
Toxicity In A Single Effluent Concentration." The monitoring shall be performed as a
Ceriodaphnia dubia 24 hour static test, usingeffluent collected as a 24 hour composite. The
effluent concentration at which there may be at no time significant acute mortality is 90% (defined
as treatment two in the North Carolina procedure document): 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 February, May, August and November.
All toxicity testing results required as part of this permit condition: will be entered on the Effluent
Discharge Monitoring Form (MR- I) for the month in which it was performed, using the parameter
code TGE6C. Additionally, DEM Form AT-2 (original) is to be sent to the following address:
Attention
Environmental Sciences Branch
North Carolina ]Division of
Environmental Management
441 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate d 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 pli with monitoring requirements.

Dear fir. Goodrich:
We appreciate the opportunity to meet with you and your staff on January 11. 1996, to discuss our request
to modify the monitoring frequency of selected parameters and upcoming NPI ES permit renewals, Also
thanks for taking time to tour our Lincoln Combustion Turbine and Riverbend Steam Station facilities.
Per our discussion concerning our letter of request (dated November 30, 1996) to change monitoring
requirements for selected parameters at the fossil stations listed above;, the $100.00 processing fee for
mirror modification of each permit is enclosed. A check of $700.00 for the seven permits is attached.
Also enclosed is a cheek totaling $16 0,00 for the $400.00 processing fee per permit for renewal of the
Plant Allen Permit No. =NC0004979,;the Lean River Steam Station Permit No. NC0002=168, the Riverbend
Steam Station Permit No. NC0004961, and the Training and Technology Center Permit NCO026 55. As
we noted in our letter dated December 22, 1995, the permit renewal applications for these four facilities
have been submitted previously, Since these submittals coincided with on -,going modification requests and
alignment of permitting with waterbasin plans, the expiration date of the modified perinits was changed to
align with their respective waterbasin plan. Because of this overlap of activities, we agreed that these prior
application submittals would suffice for this permit renewal process and that permitting renewal fees would
be paid.

Should any single quarterly monitoring indicate a failure to meet specified li ts, 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 s minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test

Dear Ms. Atherton:
In accordance with your application for discharge permit received on September 9, 1992, we
.are forwarding herewith the subject State - NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 14 -215.1 and the Memorandum of Agreement
between North Carolina and the US Environmental Protection Agency dated December 6, 1983.
Can May 17, 1993 and September 8, 1993 the Division of Environmental Management received
comments concerning the above mentioned NPDES draft permit. DEM appreciates your concerns
and comments so we may develop the best protection for the receiving waters. DEM's response to
the comments are as follows and are in the order as they appear in the May 1, 1993 letter and the
September 8 ,1993 letter':
1 The classification of ;the receiving stream has been changed to reflect the correct,
classification of WS-IV and B.
2. DEM has noted that the laboratory waste drain facilities exist and has eliminated the
Authorization to Construct language. However, an authorization to construct requirement
has been added for the physical separation for the outfalls 001 and 003:
3. N113 as N has been removed` from the effluent pages. Duk's past data on this parameter
shows that the level is well within the allowable concentration and no violation is expected.
44. The recommended limits and monitoring requirements for the radioactive substances are
fresh surface water quality standards as cited in North Carolina Regulation 1A NCAC 2P
.0211 (b)(1), These standards are reviewed for all applications for NPDES permits,; and
limits are assigned by DEM for the protection of the water quality of the receiving waters.
If monitoring data for specific radioactive substances is required by the Division of
Radiation Protection and is already being collected by Duke Power, this same data could be
reviewed for the parameters by DEM and submitted with self -monitoring data for the
NPDES permit. However, because radium 26, radium 228 and gross alpha have not
.0, Box 29535, Raleigh, North Carolina 27626-0535 Telephone 1 -7 - Q FAX[phone]
An Equal Opportunity Affirmative Action Employer 50% recycledl 1 Q post -consumer paper

shown concentrations in the effluent, items (i) and (ii) have been removed from the effluent
requirements.
5 .After review of the files, DEM will agree to the change of the test organism to
Ceriodaphnia dubia. This change will provide equal or better environmental protection.
Concerns as to the chlorine levels in the discharge and the effects on the toxicity test were
expressed. This likely will effect the toxicity test and Duke should consider some form of
dechlorination. Since 198 DEM has routinely placed WET limits in major and/or
complex discharge permits and facilities with post -chlorination so this requirement does
not represent any new initiative as was thought be Duke Power.
6. The guidelines for the toxicity test state that the sample must be collected by a composite
sample. For proper results, the composite sample must remain.
7. The language stated in Part 11, section B. 12 page 7 of 14 shall remain in the permit as
stated. For definition of the word "cause", please reference the Federal Guidelines 40 C:FP
122 Subpart D ( 122.61,122.62, 122.63, 122.64)
8.. As stated in number 5 above, DEM agrees to the change in the organism to Ceriodaphnia
Dubia. However the use of Fathead minnow would not be appropriate true to the
differences in sensitivity between the two organisms. The whop -effluent tonicity test
recommended for this discharge is meant to evaluate 'acute toxicity to fish species in an
immediate dilution area around the eutfall. The vertebrate and invertebrate species would
provide unnecessary variability ability in the sensitivity of the analysis over time and cannot be
allowed.
9. In a letter received June 28, 1993, nuke requested the addition of minimal flow from the
processor/silver recovery unittothe sanitary treatment unit with discharge through outf ll
ti t; After review of the information, DEM .finals no problem with the addition of this
wastestrearn and :has added it to the permit.
10. In the September 8, 1993 letter, Duke requested the removal of radium 226, radium 228,
gross alpha., gross beta and tritium requirements. After further review of additional data
received September 15, the requirements for radium 226, radium 28 and alpha have been
removed from the permit because they are not present in the lab effluent. However,
requirement (iii) for beta emitters will remain because they occur in the effluent.
DEM understands that Duke Power Co. plans to eliminate the discharges from this facility by
connecting the industrial waste components to Mcuire's WWTP and' routing all the domestic
from both plants to CMTD. This is an excellent decision and will be beneficial for both the
environment and Duke Power. ;However, DEM must proceed with this permit on the basis that the
relocation may not occur. This permit will expire June 30, 1995. At this time these relocation
plans will be closer to completion.

If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicative 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 150E of the North Carolina General Statutes, and 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.
Please e notice this permit is not transferable, .Fart 11, E.4. addresses the requirements to be
followed in case of charge in ownership or control of this discharge. This permit does not affect
the legal requirements to obtain other permits which may be required by the Division of
Environmental Management or permits required by the Division of Land Resources, Coastal Area
Management Act or any other Federal or Local governmental permit that may be required.. if you
have any questions, please contact Mr. Randy Kepler at telephone number 919/733-553.

performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample trust be measured and reported if chlorine is employed for
disinfection of the waste
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 reopened 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 centrals, 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.

"... of treated industrial wastewater from two outfalls into Lake
Norman, a Class WS-III and B stream in the Catawba Raver Basin."
This appears to be a typo since the basin as classified as a Class WSIV
and. B can the SUPPLEMENT TO PERMIT COVER SHEET
2. SUPPLEMENT TO PERMIT COVER. SHEET, item 2
In ,item 2 of this cover sheet, it states that. "After receiving an
Authorization to Construct from the Division of Environmental
Management, construct the connection to the laboratory
radiochemistry waste line to the influent of the waste treatment system
which discharges to outfall 001. t°
We would like to point out that the waste line from the laboratory
radiochemistry laboratories is an already existing part of the TTC
facilities. Our original request for permit modification was to request
permission to add an additional wastewater source to the sanitary
t.

system.
msX
Also, we requested that outfalls 001 and. 003 be separated physically to
allow for ease of sampling and taking flow measurements. Presently,
outfalls 001 and 003 merge prior to a shared parshall flume, The
Authorization to Construct permit may be needed to perform this
CZ
modification.
3. PART A. EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS FINAL
OUTFALL 001)" "NH3 AS
We would lake to point out that the ammonia monitoring requirement was
deleted from our most recently issued NPDES permit (issued August 3,
1992) . We feel that the addition of the ammonia as nitrogen monitoring
requirement to this permit is not warranted based upon the results of
our past monitoring :history.
4. ]PART A. EFFLUENT LIMITATIONS AND MONITORING, REQUIREMENTS FINAL
OUTFL 001) - "Radioactive Substances"
In the description of the Effluent Limitations and Monitoring
Requirements, monitoring requirements for radium-228, radium-22,
alpha emitters (including radiu s-225), and beta emitter strontium-90
are specified.
Typically, NPDES permits have NOT been used to monitor and report
radioactive substances. The radioactive substances at the TTC facility
are controlled and monitored by N. C. Radioactive .Materials License
No.. 60-0379-3 issued by the N.C, Division of Radiation Protection.

1pr'The requirements under this license provide sufficient control for the
protection of the environment. The addition of monitoring requirements
for radioactive substances in the NPDES permit will result in dual
regulation. We feel it would be more appropriate that the control and
regulation of these substances remain under the domain of the Division
of Radiation Protection.
However, if the State is interested in adopting the monitoring and
reporting of radioactive substances in the NPDES permit, we would like
to point out that many of the isotopes specified above (radium-226,
radium-228, strontium-90, etc.) are NOT present in our waste stream.
Data is available which can be used to develop a more representative
monitoring and sampling program if this is desired. However, we
maintain that it is not in the best interest of the State or the permittee
to impose dual regulatory requirements.
5. PART A: EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
FINAL (OUTFALL 001) - "Acute Toxicity"
The Duke Power biomonitoring lab <does not presently culture fathead
minnows, nor are we certified by NCDEM for this parameter, since all
other company discharges, including permitted toxicity monitoring,
require only testing. In the recently issued Belews Creek
permit, DEM agreed to allow the use of Ceriodaphnia_dubia for acute
toxicity testing at that facility instead of the fathead minnow.
It should be emphasized that under current operational practices (.1
to 1.5 mg/L chlorine residual at the NPDES sample point), this
discharge would routinely demonstrate acute toxicity to either fathead
minnows or Ceriod���ma. In order to comply with these proposed
NPDES permit requirements, a dechlorination system will need to be
placed on the discharge of the system.
DEM has not required toxicity testing in the past on outfalls with
chlorine residual. We request confirmation that DEM is requiring
toxicity monitoring on outfalls with chlorine statewide and that this
policy is being required of all discharges. If toxicity testing is
required on outfall 001, then a Schedule of Compliance will be necessary
to install dechlorination equipment.

FV . PART : EFFLUENT LIMITATIONS :D MONITORING REQUIREMENTS
FIN -- "Grab" Samples
Since the retention time of the 001 outfall is substantially greater than
0 ' days, we feel that the sampling requirement for toxicity testing
should be for collection of a single b sample, in lieu of s 24-hour
composite sample. Previous guidance from DEM to our lab personnel has
been that composite samples are required only where the treatment
basin retention times are less than 14 days, and/or the basin is not
homogeneous.
7. PART 11. SECTION B. 17 of 14 states:
"This permit may be modified, revoked and; reissued, or

To provide clarification of the work "cause" in the "sentence, ; e
recommend changing this sentence to read: "This permit may be

8. PART III "OTHER REQUIREMENTS", , SECTION "G"
Based on the previous comments, we request the language be changed
to ;require quarterly either a 4-hoar acute pass/fail fathead minnow or
C,erioda hnia test at 9Q effluent, using effluent collected as a single

Also, we request that the following language be appended to the end o

Wastewater System Description
Phase 1! Addition
July 23, 1980
E�cistin Treatment Facilities
The existing wastewater treatment system was constructed under NPDES permit
number NCO02655 for the Training and Technology Center. This system consists
of a 0.02 MG0 tubular aerated lagoon, followed by a 60,000 CPC? capacity sand
filter, and two 50,000 GPa capacity Sanuril'chlorinators. This system was in-
stalled to handle total Center sanitary needs and miscellaneous laboratory
drains.
Phase 11 Addition
Phase 11 of the Training and Technology Center will include addition of aquatic
test tanks in the laboratory. Test tanks will be installed to perform bio ni-
toring studies to evaluate the effect of potential pollutants associated with
the steam electric utility industry on the aquatic environment.
The contents of they test tanks may be natural water used as control tanks, or
specially prepared water containing potential pollutants at test concentrations.
The aquatic test laboratory will establish administrative procedures to control
the volume of water to be discharged. The test tanks will be capable of dis-
charging as much as 48,000 GPO, If this volume were combined with the remain-
der of the waste volume, then the total would be 71,260 GPD as shown can the
application. However, the administrative procedures to be established for the
aerated lagoon will control the amount of water discharged to 20,000 GPD which
can be treated effectively,
