Subject: NCS000020 - Duke McGuire Nuclear Station: Renewal of Individual Permit
Importance: High
Jennifer,
I have answer your questions to the best of my knowledge. I have several I need to follow-up on but here is what have
answers on right now. Let me know if you have further questions. As per my earlier email today maybe we can discuss
via a phone conversation on Tuesday.
1. Q: Has anything chanted significantly(industrial process or otherwise) since your last permit renewal?
a. ANSWER: No We have added several buildings but all the processes are contained within [he
buildings. The Outsourced Water Treatment Building; housed a lot of bulk chemicals for water
treatment (purification for plant water not waste wafter). Any spillage from this building would go to as
sump in the building; that is discharged to our Nvaste water treatment systent. If a spill occurred during,
chemical delivery outside of the building, the spillage would go to a large paved area and if large
enough to the WNVC11 (Waste Water Collection Basin) Outfaall 005 / SW OOf,
2. Your WW permit was renewed in 2006 -- have they contacted you about renewal yet? When is it scheduled to be
renewed?
a. Out' Wastc Water permit has been renewed as of4-01-2010
3. 1 have here that your receiving stream is the Catawba River — is that correct?
a. Correct
4. Are you aware of the Catawba River Buffer Rules? Are you planning any building?
a. We are subject to Mecklenburg County and the City of Huntersvillc water shed restrictions. We have 3
construction projects pending right now. One has an active Erosion Control plan assiociated with it.
The other 2 construction projects are rather small and are. under _ltc.1-acre suit ice a_tet_requirements

5. Why did you do analytical sampling on different dates?
aa. I have not looked at the data. I will have to check.
6. Do you have any other chemicals or materials that are outside that might be exposed.,to stormwater such as?
a. Oils?
b. Bulk chemicals?
c. "Totes?
d. Loading and unloading areas? What chemicals?
e. Other?
All are listed in the Supplemental Information document submitted with the permit re-newal package.

a. If by cooling water you mean once through cooling, water the answer is no.
8. Do you have any floor drains that drain to stormwater outfalls?
a. No Floor drains go to our waste water treatment system or our domestic sewage system which goes to

9. Outfall 001 — is that still permitted as outfall 005 under the W W permit? What are you testing for there?
a. That is correct. We have limits for TSS, Oil and (.:tease, pH and Chronic Toxicity on our 1VW (}utfall
005.
Outfall'002:=*
10. Why is groundwater monitored in the area of outfall 002? Do you have a groundwater permit?
a. We monitor for radioactive constituents at several monitoring wells near outfall 002. They are part of
our Ground Water Protection Program for radiological constituents. We have permits for the ground
water wells with Mecklenburg County.
11. What are the cyclone separators in outfall 002? Are they industrial?
They are for our Low Level Intake at the bottom of Cowan's Ford Dam. The separators are to remove
silt from the water. The water is raw lake water. I would consider them industrial activity. They are
----------------------
contained in a building.
12. What are the low level intake pumps and low-level storage? Are they industrial'?
a. The Low Level Intake draws cold water from the bottom of the lake at the bottom of Cowan's Ford
Dam. The water is mixed with our surface water intake water in the summer to help us achieve
compliance with our monthly discharge temperature limit in the summer. I would also consider these
to be industrial activity.
13. There appears to be some erosion (Re: MRO site visit in 2007). Is there a lot of stormwater or water running through
this area?
a. There is !t steady flow of water form dam leakage and the LLI pump area seal water. The erosion was i
mainly from sheet now from several sources, the major source being a old landfarnt next to the outfall.
We have done extensive repair to this area this past year and there are no erosion control issues in this
area anymore.
14. What kind of hazardous waste are you storing in this area? From where? What outfall is this going to?
a. We do not have any Hazardous Waste stored near outfall 002. Out- hazardous waste building (9[I1180
day storage) is near our falls 003atnd.005_on_the discharge canal. This is an enclosed building; with a
suntpltrench-internal_to_the_building, The sump/trench does not discharge outside of the building. The
building is also curbed and climate controlled. The hazardous waste is generated by the site (both the
McGuire Island and the plant).
15. What is the outfall located for the discarded.►nater.ials_storage building? Does that go to outfall 004?
a. See above. The closest outfall would he 0n3, altho.ngh,003„00,4„aud_()I15 are very close to each other.
The DMSB is about 1000 feet from these outfalls and is separated by a large gravel storage yard. The
building is curbed -and -the -storage area is_below-ground level
16. There appears to be an area between.outfall 004 and 005 that does not have an outfall located there — where does it
drain to?
All of these outfalls drain to the discharge canal.
17. What is the S/G storage bldg?
We used to have the old Steam Generators from the plant stored there. They were radioactive and
were stored in this building prior to disposal. We have since disposed of them (had them cut up and
removed from the site). The building is now being; converted for storage of low level radioactive
materials. Mainly tools and equipment.
18. Are there any spent materials stored outside?

19. What is stored in the warehouse in outfall 004? Is there loading and unloading there?
a. Paints and thinners. ']'here is loading and unloading through the roll -up doors and mainly by forklift.
There is an old loading dock but it is rarely used if at all.
20. What is the "discarded.materials-building" in outfall 003/4'?
a. See answer to questions 14 and 15.
21. What is in the storage yard? — loading materials for "disposal"? What kind of materials?
a. Nve mainly store steel/metal and various types of equipment. No oil or motorized equipment.
22. 1 see you had TSS exceedences from outfalls 004, 006 and 008. What do you think that was from?
a. We do not have limits on TSS ?`? 004 would be from the gravel storage yard. 006 would he from gravel
in the switchyard. 008 would be from gravel in garage storage area. The majority of the surface area
near the Garage is paved but we do have some gravel areas still. I am not aware of arty significant
erosion in these areas.
23. Are any PCB or any oil filled transformers draining to outfall 004? What about the outfalls near it? What about
outfalls 33-36?
a. None near 004 or the outfalls along the discharge canal. None near 33 — 36 either. No PCBs.
COutfalV006:7
24. What kind of transformers are stored in outfall 006?
a. Large oil tilled transformers in the switchyard. None contain I'C13s.
25. Why do you think you had a PCB exccedance in outfall 006?
a. I have no idea. All transformers and oil filled equipment in the switchyard are PC13 free. We
retrofitted all these years ago.
26. Why did you have different reporting levels? Why did you use <500?
a. Not sure. 1 will have to look at the data.
27. What Would be the sources of these in outfall 006 and 004?
a. No PCBs
28. You had a fire in this area — when?
a. No
29. Have you done any retrofitting in this area that could have caused the large PCB discharges`?
a. Years ago 20+ years ago.
30. Are any PCB or any oil filled transformers draining to outfalls near 006?
a. No
31. Dry weather discharge from fire system. However you state in your site review that there are structural areas and
interior floor drains and condensate from the equipment closed cooling system drain into the operating building sump
that is pumped out through outfall 006.
a. We have a fire suppression system for the transformers in the switchyard. Each transformer is
protected by this system. The primary leakage we observe at this outfall is from this. `]'here is a
building (relay house) that contains switching gear and batteries primarily that is inside the
switchyard. I believe the drains in this building go to our waste water system but I will have to check
on that.
32. What is SW037 — it appears to be draining to outfall 006, not from that area. Is that right? If so what is that area
draining; to?
0
a. It does not chain to Outfall 006. It drains from the storm water trench around the parameter of the
switchyard and then goes under the road to an area that eventually drains to a wetland area. We have
had some problems with erosion in this area, no so much from the switch yard but surface draining

Subject: NCS000020 - Duke McGuire Nuclear Station: Renewal of Individual Permit
Jennifer,
In my last communication to you on August 20, 2010 1 had indicated that we would need to permit 4
additional outfalls associated with the expansion of the Security Firing Range. After reviewing our
Supplemental Information provided with our re-newal application, it appears we can exempt the Firing Range
Outfalls under 40 CFR 122.26 (b) (14), the Industrial Activity Exclusion. These storm water discharges are
separate from that of our plants other industrial activities and is not mixed with those discharges. The specific
wording we are using for excluding these discharges is included below.
"...The term excludes areas located on plant lands separate from the plant's industrial activities, such as
office buildings and accompanying parking lots as long as the drainage from the excluded areas is not mixed
with storm water drained from the above described areas..."
I still owe you a copy of the PCB sample, lab bench sheets, which I hope to have by the end of business today.
will send you a copy of them as soon as I receive them.
If you have any further questions please do not hesitate to give me a call.

(B) Reagent contamination: Use high purity reagents.
(C) Contamination from sample carryover; Rinsing apparatus with hexane and purging
equipment between analyses can minimize contamination.
1 Interferences
(D) Extracted interferences: Interference from extracted non -target compounds, with retention
' times similar to target compounds, can be reduced by cleaning the extractor using
confirmation analysis.
(E) Variable solvents: Use the same solvent for each analysis.
(5) Endrin degradation: The splitless injector maycause endrin degradation. Endrin can
break down by reacting with the active sites on the port sleeve.
(G) PCBs loss to glass surfaces: Rinse glass and minimize sample contact with glass to
prevent adsorption loss of PCBs.
(H) Opdation of target compounds: Oxidation of compounds (specifically easily -oxidized
aldrin, hexachlorocyclopentadiene, and methoxychlor) can be prevented byadding sodium
thiosulfate at collection,

Dear Mr. Peterson:
William G. Ross, Jr., Secretary
Alan W. Mimek, P.E., Director
Subject: Issuance of NPDI::S Permit NCO024392
McGuire Nuclear Station
Mecklenburg County
Division personnel have reviewed and approved.your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit i6
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 (or as subsequently amended).
This final permit contains the following changes from the draft you were sent oh
August 31, 2005:
• Special Condition A.(23) was added regarding the federal requirements to comply with
the Cooling Water Intake Structure Rule per 40 CFR 125.95. This language was
mistakenly omitted from the draft permit.
• The TRC monitoring language for outfall 002 has been modified based on operations at
the facility. The new language states "TRC shall be monitored once per batch when
chlorine is used for treatment purposes."
The sample location for outfall 004 has been modified to align with a correction
granted in an April 2002 minor permit modification. The new language states
"Sample Locations: E- Effluent from the Waste Monitoring Tanks".
The intent of the boilerplate language describing DMR submittals is that DMRs be
submitted on the last day of the month following the monitoring period. Part 11,
Section D, Item 2 has been clarified to reflect this intent.
In regponsc to your comments on the draft permit:
• The results of all samples collected at permitted outfalls must be included on DMRs.
These samples should be collected according to the specified test procedures. Samples
collected at internal process points are not required to be reported on DMRs.

Please note that this permit is not transferable except after notice to the Division. The
Di�,rision 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 or permits required by the Division of Land Resources, the Coastal Area

DISCLAIMER
The lull text of certain NPDES permits and the associated fact sheets has been made available to
provide online access to this public information. EPA is making pen -nits and fact sheets available
electronically to provide convenient access for interested public parties and as a reference for
permit writers. The ownership of these dOCl1111e11t5 lies with the permitting authority, typically a
State with tut authorized NPDES program.
While EPA makes every effort to ensure that this web site remains current and contains the final
version of the active permit, we cannot guarantee it is so. For example, there may be some delay
in posting modifications made after a permit is issued. Also note that not all active permits are
currently available electronically. Only permits and fact sheets for which the full text has been
provided to Headquarters by the permitting authority may be made available. Headquarters has
requested the full text only for permits as they are issued or reissued, beginning November 1,
2002.
Please contact the appropriate permitting authority (either a State or EPA Regional office) prior to
acting on this information to ensure you have the most up-to-date permit and/or fact sheet. EPA
recognizes the official version of a permit or fact sheet to be the version designated as such and
appropriately stored by the respective permitting authority.

1.0 Proposed Changes Incorporated Into Permit Renewal
y The WE•T testa( outfall 005 will be sampled during February, May, August and November to
align with the tests taken at the other two outfall locations.
Remove hydrazine limits and monitorir%g requirements.
2.0 Summary
Duke Power Company operates McGuire Nuclear Station in Mecklenburg County at the Cowans
Forst Dam structure on Lake Norman. A detailed description of the facility and its waste streams
is provided in the attached NPDES supplement. To summarize, the Station operates five outfalls,
four of which discharge on a regular basis. These outfalls are 001, 002, 004, 005, and 006. Outfall
003 was the domestic waste discharge but has been connected to CMUD. The permitted outfalIs
are summarized below:
Outfall 001 - This outfall discharges once -through cooling water and is permitted in
accordance with 40 CFR 423 (Stream Electric Category). Specifically, limitations for total
residual chlorine come frorn 423.72 (b)(6). This being a cooling water discharge from a power
plant, thermal pollution is a concern. As such, effluent limitations for temperature are also
present. The reader will note.that the temperature limitations are somewhat higher than
those stipulated in NCAC 213 .0211, (3) 0). The facility applied for a received a 316(a)
variance for temperature. This variance is incorporated into this permit renewal. Hydrazine
is also limited as it is a common ingredient in corrosion inhibitors. The Iimit of 0.06 ppm has
been in place since at least the mid'80s. The criteria used was 0.06 ppm and is 1 /100 of the
96-hr. LC5a for the fathead minnuw. Because of the high flow from this outfall
(approximately 2530 BGn), dilution is little snore, than 1.0. As such, the appropriate
limitation is equal to the aforementioned criteria.

NNG0024392
Outfall 002 - This outfall discharges up to 0.3315 MGD of water from heat exchanger and
HVAC tube cleaning, YF filter tube cleaning; turbine building sumps, water treatment room
sumps, condcxisate den,ineralizer backwashes, closed coaling systems, the Standby
Shutdown Facility, laboratory drains, landfill leachate, steam generator blowdown, wet lay-
up, dewatering pumps, and other low volume wastewater generating activities. Treatment
consists of 200,000 gallon concrete lined initial holdup pond, two parallel 2.5 MG clay -lined
settling ponds, a concrete lined 1 MG final holdup pond, chemical addition of coagulants,
oxidants, catalysts, pl I control, and effluent pH adjustment by CO,_ addition. This discharge
is subject to 40 CPR 423.12 (b)(3).
• Outfall 004 -'Phis outfall discharges up to 0.0089 MGO of water from the Tadwaste liquid
monitoring system, floor and equipment drains, laundry drains, ventilation unit drains, and
other low volume wastewater generating activities. This discharge is subject to 40 CFR 423.12
(b)(3)_
• Outfall 005 - "Phis outfall discharges up to 0,754 MGD of standby nuclear service pond
overflow, administrative building drains, maim condenser cooling dewatering, filtered water,
HVAC unit drains, yard drains, and reverse osmosis reject flows. Treatment consists of a
13.4 acre settling pond and surface skimmer. 'Phis discharge is subject to 40 CFR 423,12 (b)(3).
• Outfall 006 - This outfall is an internal outfall to the waste treatment system (outfall 002) and
discharges chemical metal cleaning wastes on an as-neetled basis. This discharge is subject to
40 CFR 423.12 (b)(5).

R PA Analysis
Neither NC nor EPA has a water quality criterion for hydrazine. There is however an ECOTOX
guideline of 56 µg/L. An RPA was conducted using this guideline and the maximum monthly
flow front outfall 002 (highest level of hydrazine). This analysis showed an allowable
concentration (5837 pg/L) far above the maximum predicted concentration (2770 µg/L) for
hydrazine, Furthermore, a review of the historical files for this facility suggests that Duke Power
originally requested monitoring for this parameter in the 1980's, presumably to align with
administrative limits that were in place at the time. Since hydrazine is no longer a parameter of
concern, the limits and monitoring requirements will be removed from the permit.
WET Test Results
The facility has WET testing requirement,~ on 3 outfalls: 001, 002 and 005, At outfall 001
there is a 24 hr pass/fail acute testing requirement at 90%. The facility has passed 19/ 19 tests
conducted at this outfall since January 2001. At outfall 002 there is a 48-hour LC50 acute testing
requirement at 64%. The facility has also passed 19/19 tests administered for this outfall since
January 2001. Finally, at outfall 005 there is a chronic testing requirement at 1.4% effluent
concentration. 'rhe facility has passed 19/18 tests conducted at this outfall.
The facility has requested that all WET tests be scheduled concurrently. As of now they are
required to performs tests at outfalts 001 and 002 during February, May, August and November,
yet tests for outfall 005 are conducted during January, April, July and October.
Correspondence File RevietvlComphnnce Histoi�y
A review of this Facility's compliance history from 2002-2005 indicates an excellent
compliance history with no noted permit limit violah"ons.
