CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
e effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in.
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina
Chronic Bioassay Procedure - Revised *September 19 ) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 12 % (defined as treatment two in the North Carolina: procedure
document). The permit holder shall perform r- r X monitoring using this procedure to
establish compliance with the pen -nit condition. The first test will be performed after thirty
days from the effective date of this permit during the months of January, April, July
and October. Effluent sampling for this testing shall be performed at the NpDES permitted
final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition = will be entered on the
Effluent Discharge Monitoring Imo (MR.-1) for the month in which it was performed, using
the parameter code TGP3R. Additionally, DEM Form AT-1" (original) is to be sent to the
following address: ;

Test data shall be complete and accurate and include all supporting chemical/physical
measurementsperformed 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 or 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 da rn this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potentialimpacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NO Failure e 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 rotes ' g(within 30 days of initial ni orin event). Failure to
submit suitable test results ` 1 constitute noncompliance with mom " g r ui.re eats.

Subject: NPDES Permit Modification
Permit No. NCO024392
McGuire Nuclear Station
Mecklenburg County
:Dear Mr. Carter:
It has came to the attention of the Division that several errors exist in your currently issued NPDES
permit. In accordance with this determination, your'NPDES permit has been modified to reflect
appropriate changes. In the July 31, 1995 correspondence to this officefrom Norma Atherton of
Duke Power, several issues were raised. These issued have been addressed as follows-
1 . Outfall 001 limit for Total Residual Chlorine has been modified to 0.20 mg/I
daily maximum with no monthly average specified.
2. Although the cover letter accompanying the issued permit stated "After
September 1, t997, the limits will change to 30 mg/1 and 60 mg/1" the permit
reflects the appropriate phased limits of 30 mgil and 100 mg/l' for T S at o tfall
003.
3. The units for Ml3AS at Outfall 003 have been changed to mgll.
4. The units for iron and copper at Outfall 005 have been changed to µg/l.
5. The definition of a time weighted composite sample for the acute toxicity test at
Outfall 001 has been defined in the footnote on the effluent page.
6. The cover letter accompanying the issued permit erroneously stated "outfall 004
effluent limitation and monitoring requirements" with respect to Part III,
Condition G. The reference should have been to Outfall 002, but does not
affect the issued permit.
7. The acute toxicity sample for Outfall 002 has been changed to a grab sample as
specified on the effluent page and in Part IlI, Condition G.
Attached to this correspondence are the amended pages which should be inserted into your permit.
The corresponding existing pages should be discarded. All tither terms and conditions contained in
the issued 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.

Duke Power must perform the following as part of the 16(a) variance:
a. Monitoring shall include a sampling program with intent to determine the
abundance and distribution of fish species, both in time and space, in the
mixing zone over the critical summer period. The use of hydroacoustical
sampling equipment is suitable for these purposes and is to be performed in
conjunction with vertical temperature and dissolved oxygen profiles. In
addition, these data will be analyzed where appropriate (using other lake
specific information collected either by Duke Power Company or other
agencies)'' with regard to striped bass usage of the mixing zone.
b . Remodel and assess the impact of 100% load factor during the months of
June -August and 90% load factor for the remainder of the year.
c. Address maximum discharge temperatures from McGuire which will occur
each month when the units are operating at maximum um output. This
discussion shall entail the possible effect on swimmers/fallen skiers in the
thermal plume area during g the summer months.

The following comments are provided in response, and in corresponding order, to the
issues raised in your June 20, 1995 comments on the draft permit:
QMIUI QQ I
• The federal effluent guidelines specify Free Available Chlorine monitoring. However, Total
Residual Chlorine is a more stringent requirement, and as such, Total Residual Chlorine
monitoring is included in the permit renewal as requested. This change also resolves the
ambiguity contained in footnote "Y'.
• The chlorine monitoring language contained in the previous permit is included in the permit
renewal as requested.
• Selenium is not a byproduct of nuclear generation and monitoring has been deleted as
requested.
99tul QQ2
• As requested, nutrient monitoring parameters have been deleted for outfall 002 in favor of
monitoring at the final outfall prior to discharge.
• The frequency for MBAS monitoring remains at monthly intervals. This frequency is deemed
necessary to characterize a representative discharge at this outfall. The currently scheduled
1997 addition of a car wash at this outfall will also require a minimum of monthly monitoring
for MBAS.
• The draft permit included MBAS with specified units of Rg/l, in keeping with the state water
quality standard units. The limits have been changed to mg/I as requested.
• Because this facility is actively working towards connecting all possible discharges to the
municipal sewer system, the permittee may petition the Division to evaluate the requirement for

generation and monitoring has been deleted as
the permittee may petition the Division to evaluate
er if, after 6 months of monitoring under the terms
at silver is not a parameter of concern. Six months
ew a minimum of twelve data points.
• The monitoring frequency for hydrazine has been changed to "batch" as requested.
• The draft permit lists weekly flow monitoring and is unchanged since weekly flow monitoring
was requested.
• The monitoring frequency for total suspended solids and oil and grease should have been listed
as quarterly in the draft permit and have been changed to quarterly as requested.
• Application documents indicate that outfall 004 combines with outfall 001 prior to discharge
d that turbine building sumps may be discharged through outfall 002. Outfall 002 is the
conventional water treatment system and incorporates the same effluent limits as otfall 004.
Therefore, the wording has been changed to "In the event the turbine building sumps are
discharged through Outfall 001 instead of Outfall 002, the above discharge limitations shall
also apply to the turbine building sump discharge" as requested.

• Nutrient monitoring requirements at outfalls 002 and 003 have been deleted in favor of
monitoring nutrients at this outfall where the flows combine prior to discharge to the Catawba

E. 316(a) Variance
The Division of Environmental Management has approved the submitted 316(a)
demonstration and has concluded that the existing thermal limitations are sufficient to
protect the aquatic environment of Lake Norman.
Duke Power must perform the following as part of the 316(a) variance:
a. Monitoring shall include a sampling program with intent to determine the
abundance and distribution of fish species, both in time and space, in the
mixing zone over the critical summer period. The use of hydroacoustical
sampling equipment is suitable for these purposes and is to be performed in
conjunction with vertical temperature and dissolved oxygen profiles. In
addition, these data will be analyzed where appropriate (using other lake
specific information collected either by Duke Power Company or other
agencies) with regard to striped assuage of the mixing zone.
b . Remodel and assess the impact of 100% load factor during the months of
June -August and 90% load factor for the remainder of the year.
c Address maximum discharge temperatures from McGuire which will occur
each month when the units are operating at maximum output. This
discussion shall entail the possible effect on swimmers/fallen skiers in the
thermal plume area during the summer months.
