Subj ect: Five Day Written Follow-up Notification of Oil Spill to Ground
McGuire Nuclear Station
Dear Mr. Bell:
This correspondence serves as the five day written follow up notification of the oil
release at McGuire Nuclear that was reported to you by phone on November 8, 2017.
This release was due to a transformer fire due to a component failure at the McGuire
Switchyard and subsequent firefighting efforts.
The transformer contained a total of 16,133 gallons of transformer oil, HyVolt 11. A
conservative estimate of half of the transformer oil, approximately 8,000 gallons, was
reported as spilled to the ground due to the initial fault and equipment failure.
A majority of the oil was routed to an oil and water separator through a series of
drainage trenches as designed, Oil and firefighting foam also flowed to four nearby
stormwater drains that were routed to two stormwater outfalls SW006 and SW037.
Gravel coffer dams, oil absorbent boom, and oil pads have been placed at these
outfalls.
The firefighting foam initially overwhelmed the oil and water separator and a discharge
of firefighting foam was released through stormwater outfall SWO14 and SW024. We
believe the small amount of oil we observed in the adjacent wetland area and
subsequently reported to the National Response Center of less than one pint was
carried by this firefighting foam. The observed oil in the wetland area was absorbed by
an oil pad and removed. No subsequent sheen has been observed in the area.
Storm drains are currently undergoing high volume flushes to remove any residual oil.
Vacuum trucks continue to work to remove any residual oily water mixture as well as
clean out the oil and water separator.

Within the switchyard, the gravel area surrounding the transformer is currently being
excavated.. An area of approximately 3,000 square feet and 6-8 inches deep is being
removed. The majority of the oil near the transformer was absorbed by a layer of
carbon beneath the gravel that was pert of the original switchyard design and has been
removed as well.
n area of approximately 2,000 square feet beyond the convergence point of outfall
SWO06 and SW037 will also be remediated. There is currently are earthen coffer dam
with an 3 inch corrugated dewatering pipe with a raised midsection surrounded by oil
absorbent boom and pads preventing further oily water migration. Contractors with
vacuum trucks are continuing to remove water from this area. We should begin
removing contaminated soil this week after we have completed flushing the upstream
switchyard trenches and storm drains. All contaminated material will be properly
disposed of via certified contractors.
If you have any questions concerning this report, please contact Macrae Walters by
phone at (80) 75-5 35 or by email at [e-mail]. Or, you
can contact John Williamson at (3g) 375-5394 or by email at John.Williamson@Duke-

Subject: Owner Affiliation and Facility Contacts for North Carolina NPDES Correspondence
Duke Energy NPDES Permitted Facilities
Dear Mr. Poupart.
As discussed with you by Richard Baker and Shannon Langley on July 5, 2€717, Duke Energy has recently
noted an increased number of documents and correspondence from your agency being directed to the
attention of incorrect staff persons for our NPDES permitted facilities. A few recent examples include
the annual NPDES inspection report for the Mayo Steam Station and a Notice of Violation for the Cape
Fear plant being sent to the Vice President of Harris Nuclear Plant; as well as correspondence for the
Allen Steam Station sent to the South Carolina Director of Environmental Policy. In each case, this has
led to delays in the permitted facility receiving information and impacts our ability to provide time
sensitive responses to the Department of Environmental Quality (DEQ).
Duke staff have discussed this situation with DEC€, staff in the central and various regional offices. Based
on our conversations and a review of information captured in your RIMS system, we believe the best<
way to address this is with the following included information:
1. A single name/ownership change farm to request that the "owner affiliation" for entities Duke
Energy Progress, LLC (DEP) and Duke Energy Carolinas, LLC (DEC) be updated with my contact
information. There appear to be numerous obsolete contacts listed as "owner contact persons"
in your RIMS database- that field can be updated to include my name and the Gathers removed.
2. The "permit billing contact person" should be updated for all facilities to name Cynthia Winston,
Manager, 410 S. Wilmington Street, NCRH'15, Raleigh NC 27601 She can be reached at
(919)56-553 and cnthia.insto duke-enerv.com.
3. The "facility contact person" for each facility should reflect the Station Manager at the site. A
list of current Station Managers for all DEP and DEC facilities is attached to this correspondence.
4. The fields for `"permit contact person" and "persons with signatory authority" have been
recently updated as part of the e-dmr registration process and appear accurate as of this time.
Based on this information, I would envision that general correspondence applicable to more than one
Duke Energy facility, such as groundwater information or other programmatic issues, should be directed

Mr. Jeff Poupart
August 4, 2017
to my attention, while station specific communication should be directed to the Station Manager for the
site, Duke Energy will continue to routinely update the DEQ in a timely manner when facility contacts
change. If you think it would be helpful, we would be available to meet with your staff to discuss the
best way to assure accurate delivery of correspondence, We are providing copies of this letter to each
of the regional office supervisors responsible for NPDES permit oversight.
If there are any questions relating to this request please contact Anne Pifer at (980)-373-1609 or
at [e-mail].

Subject: Shade Treatment on the WWCB at MNS
Good morning, Mr. Bell
We are going to perform a shade treatment of the WWC;B (wastewater collection basin) at MINIS today using one of the
two previously approved black dyes. We will be using the Black Onyx this time as opposed to the mystic black we used
last time. We will be dosing at the previously approved levels as well. This is one of our measures to control pH and
algae growth for the WW B that discharges to outfall 005. We do not anticipate any overflow to the river at this time as
there is no rain in the forecast until the weekend but an unforecasted rain event could cause some overflow. Please let
me know if you have any additional questions.

Good afternoon, Wes.
I called on Thursday, but as you were in the field, I wanted to follow up via email. We will be treating the WB at MNS
with the dye you all approved last year at the same concentration. We have this scheduled for Monday as we are trying
to get ahead of any early blooms. We are keeping the level of the WWCB low to try to avoid any overflow from minor
rain events. Please let me know if you have any questions or concerns. Thanks and have a great weekend!

We would like to treat the WW B (Waste Water Collection Basin) that discharges to Qutfall 005 with dye to help control

As requested, we had toxicity tests (i day chronic) performed on the 2 pond dyes we would like to use in the WWB
(Outfall 005) to help control algae and pH. We had the lab perform a dilution series at 6, i, 8 9,10, and 11 ppm on the
dye in soft synthetic water. We plan to treat the WCB at8 ppm.; Both dyes pasted the tests. The test results are
attached.
We would hike to use the Mystic Black Dye as the Black Onyx is no longer available.
Please advise if it is ok to proceed with the dye treatment, We would like to perform the dye treatment as soon as
possible as we are having pH issues on the WWCB. It is currently pumped down below overflow to prevent a potential
discharge of water over the pH limit.

Subject: NPDES Electronic Reporting Requirements and
Sixty Day Notice of Minch Modification of the NPDES Permit
McGuire Nuclear Power Plant
NPDES Permit Number: NCO024392
Dear NPDES Permittee:
The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge
Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to
report information electronically, instead of filing written paper reports, The rule does not change what
information is required from facilities. It only changes the method by whichinformation is provided (i.e..,
electronic rather than paper -based).
EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their
key milestones, are:
• Phase 1—Starting can December 21, 2016, regulated entities that are required to submit Discharge
Monitoring Reports (DMRs) will begin submitting these reports electronically, instead of on
paper. if you are currently reporting your DMR data electronically using eDMR, then you simply
need to continue reporting in the same way as you are now, The key change is that, starting on
December 21, 2016, electronic reporting of D Rs will be required, instead of voluntary.
• Phase 2—Starting on December21, 2020, regulated entities that are required to submit certain
other NPDES reports will begin submitting these reports electronically, instead of on paper.
Reports covered in the second phase include Notices of Intent to discharge in compliance with an
NPDES general permit, Sewer Overflow/Bypass Event Reports, and a number of other NPDES
program reports.

McGuire EHS (Environmental, Health & Safety) was notified on Thursday; 2/ 16/2012 that the; test results were
not looking good after 21 hours. The test takes 48 hours to perform.
FES notified Chemistry of the potential for failure and the discharge was stopped around noon on 2/16.
Chemistry and EHS began to investigate potential failure mechanisms.
Later in the day at around 4 PM another email was received from the toxicity lab by EIS that indicated the
sample would fail based on results at 29 hours into the test. The LC50 = 62.9% at that time. Permit limit
64°
The test was completed on 2/17/201 with a final LC50 of 55.. FES was notified via email and phone call of
the failure.
FES (John Williamson) notified the OSM (Operations Shift Manager), Alvin Perdue that we would have to
notify Mooresville of the test failure at around 130 hours. Per -10 Operations notified the NRC. See PIP
f-12-1241
EHS (John Williamson) contacted the Mooresville office of NCI ENR and notified Mr. Mike Parker of the
toxicity failure at around 1330. Mr. Parker asked to be kept informed of our investigation results.
A retest of Outfall 002 is required within 30 days; A re -test on the discharge will not be perforined until we
determine if the water to be released is toxic or not (should know this by Monday or Tuesday). No release of
Toxic water will be made.
The following actions have been Taken to address this issue.
Chemistry stopped the discharge of 002 on Thursday around noon after receiving word that the discharge would
likely fail the toxicity test.
Chemistry verified that the correct sample had been sent to the toxicity lab and that the lab had analyzed the
correct sample. The sample was pulled on Feb. 14.
EITS and Chemistry began investigation into what further actions should be taken.
After consultation. with Corporate EHS, ET (toxicity lab), Chemistry and EHS, it was determined that we
would pull samples from the WC Pond and the Initial Holdup Fond and have them tested for toxicity to
determine if we still have a toxic WC bond:
Samples were pulled by Chemistry and EHS took them to the toxicity lab (in Asheville N ) Friday afternoon
for analysis.
Results from these test still indicated that flip WO-11 Pond was still toxic.
Further investigation into the cause and source of the toxicity will be performed.
Chemistry and OPS are looking into any potential "events" that may have occurred

Dear Mr, Hamilton.
This Office was contacted by Mr. John Williamson of Duke Energy on October 4, 2010 in
response to the above referenced Notice of Violation (NOV). Mr. Williamson informed our Staff of an
error correction for NCO2432 that was issued by the Wastewater Permitting Unit on March 18,
2010. The error correction removed the quarterly copper and iron monitoring at Outfall 005,
Unfortunately, the error correction was not attached to the permit in our Office and the change in
monitoring requirements has not been made in our Compliance Reporting Database, Our Office will
follow-up to ensure the erroneous monitoring requirements are removed from the database for
NCO024392 and through this letter we are rescinding NOV-2010-MV-01 34.
If you have any further questions concerning this matter, please do not hesitate to contact Ms Allocco

Comments'
1. In other environmental monitoring reports that are submitted by Duke Energy to DWQ to fulfill 316(a) obligations
(e.g., page 1-2 of the November 2009 Allen Steam Station Report), "boiler plate" language is used to instruct the
reader as to the definition of a balanced and indigenous community as first described in the Clean Water Act and
later defined in 40FR15.71():
"Assessment of the potential influence of thermal discharges on biological communities is a key
component of thermal discharge variances granted under section 316(a) of the Clean Water Act (C A).
The term "balance, indigenous community" [40CFR125 71(c)] is synonymous with the term "balanced
indigenous population" its the CWA and refers to a biotic community typically characterized by diversity,
the capacity to sustain itself through seasonal changes, presence of necessary food chain species, and a
lack of domination by pollution tolerant species. Such a community may include historically non-native
species introduced in connection with a program of wildlife management and species whose presence or
abundance results from substantial, irreversible environmental modifications (USEPA 1 77)"
We encourage you to include this language in future reports for the McGuire Nuclear Station because it will aid
reviewers as to the purpose of the environmental monitoring studies which are conducted to support continuation
of the 316(a) variance.
2. Limnological data, presented in the report are similar to that previously collected by DQ's Intensive Survey Unit
from Lake Norman. And as in past years evaluations, algal; assemblages and their related densities remain well
below levels that could be considered problematic. Seasonal trends and shifts in composition follow those
expected to occur in piedmont reservoirs throughout the year.
If you have any questions, please do not hesitate to contact me or my staff.
Yours truly,
Jay Sauber

Requested Permit Changes
McGuire Nuclear Station requests the following permit changes:
Removal of the following parameters for Outfall 005
• Total Recoverable Copper
• Total Recoverable Iron
The iron and copper limitations were added to Outfall 005 because we anticipated that
Chemical Metals Cleaning Wastes (CMCW) could be discharged from this outfall. We
no longer plan on discharging any CMCW wastes ` to this outfall, so it is appropriate to
request removal of the iron and capper monitoring requirements. We have toxicity
testing on this outfall on a quarterly basis.
McGuire Nuclear Station 316 JbIReview
e would like to request that the current references to 31 n(b) be removed from our
permit until EPA publishes a final rule can this issue:

discuss our waste water operations with personnel who are knowledgeable with its
operation first hand. If a site visit is not possible, we would be glad to come to Raleigh to

OVERVIEW
The McGuire Nuclear Station is a two unit nuclear steam electric generating station. It is owned
d operated by juke Energy Corporation. Each unit has a fourloop pressurized water reactor,
Reactor fuel consists of uranium oxide pellets clad in zirconium alloy fuel rods. Reactor heat
absorbed by the Reactor Coolant System (primary side) is transferred to four steam generators to
produce steam (secondary side) sufficient enough to drive a turbine generator with a design net
electrical rating of 1180 megawatts.
The nuclear reaction is controlled by control rods and chemical neutron absorption. Boric acid is
used as a chemical neutron absorber and to provide borated water for emergency safety injection.
During reactor operation, changes are made in the reactor coolant boron concentration.
schematic diagram of water use and waste water discharges for McGuire Nuclear Station is
attached as Appendix 1. It is possible for any of the discharges to contain low levels of
radioactivity, All discharges of radioactivity are regulated by the Nuclear Regulatory
Commission in accordance with 10 CFR fart 20 and 10 CFR Part 50. The following is a brief
description of the major systems.
STATION
All water for McGuire Nuclear Station is withdrawn from Lake Norman through a dual intake
system, a surface and a subsurface system. These systems supply the Main Condenser Cooling
Water RC), Conventional' Low Pressure Service Water (), Nuclear Service Water (RN), Fire
Protection System /RY), and Containment Ventilation Cooling Water System (RV).
Surface Intake
McGuire Nuclear Station has two power generating units with four Condenser Cooling Water
(RC) pumps per unit. There are two intake screens per pump for a total of 16 screens. The
intake screens are back washed on an intermittent basis to prevent differential pressure buildup
across the intake screens. The frequency of cleaning is determined by the amount of debris on
the screens. Approximately 8,500 gallons of water are used to backwash each screen. The water
is returned to Lake Norman at the intake bay. The backwash water is raw lake water. No
chemicals are used in the backwash water.
Subsurface Intake
The subsurface intake (Low Level Intake) is located near the bottom of Lake Norman at Cowans
Ford Dam. There are six low-level intake pumps with a capacity of 150,000 GPM each.
Currently only 3 pumps are operational. The Unit I pumps have been taken out of service.
During certain times of the year, this system pumpscoolerwater from the bottom of the lake
(hypolimnion - perpetually colder water in the lower part of the lake) and mixes it with the
warmer water in the surface intake structure during times of high lake surface water
Page 4 of 24

temperatures. At all times of the year, the Low Level Intake (LLI) supplies water to the ITV and
RN Systems.
The LLI lines are periodically drained to the Catawba River just below theCowan's Ford Liam
for inspection.
NUCLEAR SERVICE WATER
The Nuclear Service Water (RN) System is a safety related., once -through, ;non -contact Cooling
water system. The RN System supplies cooling water to various heat loads in bath the primary
and secondary portions of each unit. -There are two pumps per unit (four pumps total) that are
capable of delivering 17,500 GPM per pump. The water supply is from Lake Norman or the
Standby Nuclear Service Water Pond (SNSWP). Water from Lake Norman is supplied by the
C system from the surface intake or by the Low Level Intake (LLI). The normal source of
water is the LLI system. The normal discharge is to Lake Norman through C utfall 001.
The SNSWP,is a 34.9 acre pond designed to provide cooling water for the safe shutdown of the
station in the unlikely event that Lake Norman becomes unavailable. The level in the pond i
maintained, per requirements of the McGuire Nuclear Station Technical Specifications, b
pumping water from Lake Norman into the pond. The pond overflows to the Catawba River via
the Wastewater Collection Basin (WWCB), Outfall 005. The pond also receives storm water
runoff from a drainage area. of 100 acres, When the RN System is aligned to take suction from
the SKIS , discharge is back to the SNSWP. This recirculation mode is normally implemented
for three hours every six weeks.
s a result of accelerated corrosion of RN System components, some components have corrosion
inhibitors added. Corrosion inhibitors may contain nitrites, borates, carbonates, silicates,
hydroxides, tiazoles, and azoles, Low levels of one or more of these corrosion inhibitors would
e discharged at environmentally acceptable levels:
Macrotouling by C rbicula (Asiatic clams) and Dreissena (Zebra Mussels) can impact the safe
operation of the station. Zebra Mussels have not been problematic to date in bake Norman but
ether utilities have experienced macrofouling with :Zebra Mussels. Microbial influenced
corrosion (M C) has caused failures of piping and heat exchanger tubing due to pitting. Non -
oxidizing biocides, chlorine, or sodium h pochlorite may be used at concentrations, which will
not impact the environment to address macrofouling and MIC. Surfactants, which act as
biopenetrants may be added along with biocides to improve their efficacy. To prevent mud
fouling of components coaled by the RN System, dispersants are added.
CONTAINMENT SPY HEAT EXCHANGERS
In order to mitigate corrosion of carbon steel, a wet lay-up system is being used on the
Containment Spray Heat Exchangers (N ). Various corrosion inhibitor solutions containing
nitrites, borat s, axles, and trig oles may be used. The corrosion inhibitor solution is released 5
to 10 times per year per heat exchanger (2 heat exchangers per unit) to either the SNSWP or
Page 5 of 2

Lake Norman via Outfall 001, during the flaw balance and heat exchanger performance testing.
Each heat exchanger has a capacity of3600 gallons. Organic biocides are added for biofduling
control.
OUT1N A.LL 00
Inputs to Outfall 001 include discharges from the R, RL, and RN systems. Outfall 004
combines with Outfall 001 before discharging into Lake Norman. Storm drains along the
discharge canal combine with Outfall 001;
Page 6 of 24

Condenser Cooline Water
The RC System is a once through, non -contact cooling water system that removes heat rejected
from the main and feedwter pump turbine condensers and other miscellaneous heat exchangers.
Each of the two power generating units has four RC pumps for a total of eight (8) pumps, The
flow for each unit depends on the number of pumps operating as shown by the following table:
i
r.i
The operational schedule of the pumps of each unit is a function of the intake water temperature
and the unit load. At 100% load and with the intake temperature near its summer high, three and
sometimes four, RC pumps per unit are used. During winter when intake temperatures are lower,
three pumps may be used.
Condenser cleaning is accomplished by mechanical means using; the "mertap" system. This
system circulates small sponge rubber balls through the condenser continuously. There are 8
Amertap pumps per unit, 16 altogether. Each system (2 systemsper unit, one for main
condenser and one for the FWPTs (Feedwater Pump Turbines)) has a capacity of approximately
120 balls. The balls are injected on the inlet side of the condenser and are retrieved on screens
n the discharge side of the condenser. Periodically some balls escape the retrieval system and
are discharged through Outfall 001. Efforts are made to minimize the loss of balls within the
system.
It may become necessary at times to institute chemical control for macroinvertebrate infestation;
general corrosion, and microbiologically induced corrosion (IC). Chemicals anticipated to b
added include chlorine (sodium or calcium hypochlorite), organic biocides, dispersants, and
corrosion inhibitors. The corrosion inhibitors include nitrites, carbonates, tri toles, borates,
triazols, and azoles. Discharge concentrations are maintained below permitted discharge levels,
MNS has identified the need to treat for Asiatic clams in a section of the RC system; The site
has determined that clams are present in a "crossover pipe" that connects the U I and U2 RC
systems. The clams have caused fouling of plant components. It is planned to periodically
perform localized injections of a clamicide, EVAC, into the crossover pipe section. The
injection concentrations will be kept at a level to prevent toxic conditions at the plant discharge.
Discharge concentrations of any treatment chemicals will be maintained below permitted
discharge levels.

The Ventilation Unit Condensate Drain Tanks ( CDT) collects condensate fromairhandling
units from each reactor building. Each VUCDT (1 per unit) has a volume of 4,000 gallons,
This condensate typically has little radionuclide contamination. The condensate is sampled for
radionuclide contamination before being released. If the results of this sampling indicates the
need, the VUDT contents are transferred to the Floor Drain Tank (FDT) for processing through
Outfall004. If no processing is needed, the condensate is released from the VUCDT via the RC
System piping to Lake Norman (Outfall 001).
Note: Outfall 004 and the VUCDTs discharge through the same piping to Lake Norman through
Outfall 001,
During refueling outages, the ice in the ice condenser is melted. The ice melt is normally routed
to WC via the Turbine Building Sumps, however on occasion the ice melt may be routed through
the VUCDT. This drainage contains small amounts of boron. Boron is used as a neutron
absorber in the ice to control reactivity.
Additionally,' small amounts of oil have also been found to accumulate on the ice in the ice
condensers. The source of the oil is from pneumatic tools used to vibrate the ice from the
condenser's ice baskets.
Luring outages the KC Heat Exchangers may be drained to the CDT as well. Permission was
granted for this discharge in a permit modification approved by NCDENR on April 11, 2002.
316 (a} Study and Thermal Variance
31 o() study was submitted to the state on August 9, 1985 and a 31 t(a) variance was granted
on October 1, 1985. Plant operating conditions and load factors remain unchanged and are
expected to remain so for the term of the permit. An annual Lake Norman aquatic environment
maintenance monitoring program was implemented on July 8, 1987, A copy of this report is
submitted annually to the Environmental Sciences Section of the Division of Water Quality at
NCDENR and. the NC Wildlife Resources Commission. No obvious short term or long term
impact of station operations have been observed in water quality, phytoplankton, zooplankton or
fish communities since the inception of this program., Additionally, Doke Energy is not aware o
any changes to plant discharges or other discharges in the plant site area which would negatively
impact the thermal discharge or biological habitat of Lake Norman,
OUTF LL 002
Outfall '002 discharges treated wastewater from the Conventional Wastewater Treatment (C)
System through a Parshall flume to the Catawba River below Cowans Ford Dam. The WC
System' consists of a concrete lined initial holdup pond (200,000 gallon capacity), two parallel
Page 8 of 24

clay -lined settling ponds (2.5 million gallons each), and a concrete lined final holdup pond (1
Inputs to the Water Treatment Room Sump consist of drainage from all equipment including
pump seal le off and bearing cooling water located in the Water Treatment Room, Other inputs
include the Diatomaceous Earth (DSlurry Tank drain, Filtered Water ( F), Acid and Caustic
day -tank storage overflow drains, Carbon Filter backwash and sluice, filter backwash, YM
demineralizer regeneration waste, rinsate of empty hydrazine, ammonia, carbohydrazide,
dimethylamine containers and backflow preenter drains. In addition, floor wash and sample
line flush water are routed to this sump. Antfoa ing agents and wax strippers are routinely
present in this waste stream. Rinsate :from empty microbiocide containers (used in the chased
Page 9 of 2

cooling systems) are periodically added to this sump. The drains in the plant Auxiliary Electric
Boiler Room also route to this sump. Additionally, inputs from the McGuire Island Industrial
Waste System are routed to the sump. See the Island industrial Waste section: for additional
details on these inputs. The Water Treatment Room Sump discharges to the WC System via the
Initial Holdup Fond..
new building has been constructed on site that will contain a vendor supplied water treatment
system to replace the existing treatment system. The conversion; is planned to be completed by
late 20 10. At that time, any water treatment related waste streams will no longer be routed to the
current Water Treatment room sump. Wastes from the new processes will be still be routed to
the WC system. See New WaterTreatment wilding discussion below.

in use, while the other demineralizer is being regenerated or in standby. YM pumps take suction
from the Filtered Water (YF) Storage flanks and discharge through the Carbon Filters to the RO
units. The RO units discharge to holding tank(s) which discharges to the YM demineralizer in
service. The RO units can be bypassed during high water demands:
The carbon filters remove organic substances and any residual chlorine. These filters may be
cleaned by backwashing, steam cleaning, or rinsing. Backwashing is usually performed weekly
on alternating filters. Rinse water is discharged via the Water Treatment Rohm Sump to the WC
System (utfall 00). Approximately 15,000 gallons of water is used per rinse. Each carbon
bed is sluiced and reloaded with new carbon as needed. 'Waste carbon is rousted to the WC Initial
Holdup Fond where it is collected and deposited in a permitted landfill. Waste carbon may also
be collected directly from the carbon filter and deposited in a permitted landfill
The RO units provide pretreatment to the demineralizers. They consist of a high pressure pump
for each unit which forces water through a series of membranes which cleans a portion of the
water (approximately 300 GPM) to a acceptable level (permeate) and sends the rest of the water
(reject water of approximately 10 GPM) to the Waste Water Collection Basin (utfall 005),
Sulfuric acid can be injected to the process stream to maintain proper pH. The RO Units are
periodically cleaned based an performance standards. The cleaning process may involve the use
of surfactants, acids and caustics. When cleaning is conducted, the cleaning water is discharged
via the Water Treatment Sump and then to the WC System (Out all 002).
Demineralizers are regenerated based on through -put or chemistry limits on contaminant levels.
To regenerate the resins, sulfuric acid and sodium hydroxide are flushed through the bed. At the
present time, each regeneration normally takes approximately 200 gallons of 93% Sulfuric Acid;
00 gallons of 50°r'o'Sodium Hydroxide and 75,000 gallons of YM water. The amounts of
required acid and caustic will vary as dictated by operational requirements. Based on annual
resin analysis results, the beds may be surfactant cleaned, caustic soaked or brine soaked. The
water from these cleanings is discharged via the Water Treatment Room Sump to the WC
System (Outfall 002), The demineralizer resin is replenished approximately every six to eight
years depending on resin sampling results. Waste resin is routed via the Water Treatment Room
Sump to the WC System, Initial Holdup Pond and is ultimately placed in a permitted landfill.
Waste resin may also be collected directly from the ion exchange vessel and either recycled if
reusable, or deposited in a`permitted landfill.
With the new vendor water treatment system, the existing demineralized water system will be
abandoned, eliminating wastes from these wastestrea s. See New Water Treatment Building
discussion below.
New Water Treatment Bolding
The site is in the process of replacing the existing water treatment system with a new vendor
supplied system. While the processes will be similar, there will be some changes to waste
streams: The treatment processes will consist of chlorination, filtration, dechlorinaton, reverse
osmosis, electrodeionization(EDI) and ion exchange:
Page 11 of 2

Sodium hypochlorite will be used for chlorination. Instead of diatomaceous earth filters,
ultrafiltration (UF) will be used. This will eliminate the waste filter media (DE) that is currently
produced. The OF filters will be backwashed periodically to remove accumulated lake solids.
At times cleaning cycles will be combined with backwashes for the Ulu filters. Sodium
hypochlorite, hydrochloric acid and sodium hydroxide may be used to clean the OF fibers,
Backwash and cleaning waste water will be routed to the WC system for treatment. OF filtered
water will be pumped to a 25,000 gallon storage tank at the new building.
The new process will not use carbon filtration, eliminating carbon filter backwash wastewater
and the need to dispose of waste carbon. Sodium bisulfite will be used to dechlorinate filtered
water before it is pumped to the reverse osmosis units.
Reverse osmosis will operate the same as currently with reject flow, approximately 100 gpm
max flowrate, routed to the Wastewater Collection Basin. Antiscalents can be injected into the
RO feed. The RO system will require periodic cleanings using surfactants, acids or caustic
chemicals. Any spent cleaning solutions will be routed to the WC system for treatment.
The new system will also employ an electrodeionization (EDI) unit to remove dissolved minerals
from the water. Reject water from the EDI unit will be sent back to the OF filtered water storage
tank for reprocessing. The EDI unit will also be cleaned periodically with the same cleaning
system used for RO.
The existing demineralization system will be replaced with modular, replaceable mixed ion
exchange resin beds. When the resin beds are exhausted, they will be replaced with new resin
beds and transported off site for regeneration. This will eliminate the demineralizer waste
streams including the 75,000+ gallons of regenerant wastes currently sent to WC.
Turbine Building Sum s y
The Turbine Building Sumps (TBS), one for each unit, receive inputs from leakage, drainage,
and liquid wastes from equipment and floor drains located in the Turbine Building. Inputs
include Groundwater Drainage Sumps (WZ), Auxiliary Electric Boiler Blowdown, Steam
Generator Blowdown, air handling units, Diesel Generator Room Sumps, lab drains, floor
washes, normal condensate system leakage, and condensate polisher backwashes. Other possible
inputs may include RC Un-watering, closed cooling system drainage, and steam generator wet
lay-up/drain down. Periodically, condensate from air compressors is processed through an oil
water separator and routed to the TBS then to the WC Initial Holdup Pond. The TBS's pump out
to the WC Initial Holdup Pond. If radioactivity limits are exceeded, theses sumps may be routed
through the Radwaste Liquid Waste Monitoring (WM) System (Outfall 004) or directly to RC
(Outfall 001) depending on the treatment needed. All radioactive releases are controlled and
regulated by the NRC. Discharges from the TBS may also be routed to RC (Outfall 001) if
system inventory is high.
Page 12 of 24

Chemicals that may be present in the TBS include the following:
• ammonia
• hydrazine
• carbohydrazid
• 3-methoxypropylamine (MPA)
• dimethylamine (DMA)
• microbiocides
• corrosion inhibitors (examples include: molybdate, nitrite, tolyltriazole, etc.)
• ,janitorial cleaning products
• ethylene glycol (from ice melt
• Boric Acid / Borax (from ice melt)
• miscellaneous system/component cleaning products (love --volume wastes not associated
with chemical metal cleaning)
• laboratory chemicals
• poly acrylic acid (P'AA)
• surfactants
• dispersants
Curing refueling outages, the ice in the ice condenser is melted. The ice melt is routed to W
via the Turbine Building Sumps, This drainage contains small amounts of boron. Boron is used
s a neutron absorber in the ice to control reactivity;
Additionally, small amounts of oil have also been found to accumulate on the ice in the ice
condensers. The source of the oil is from pneumatic tools used to vibrate the ice from the
condenser's icebaskets'.

Lab [trains
There are several analytical laboratories on site which discharge to the WC System. These
discharges contain small quantities of typical laboratory chemicals used in analytical procedures:
The island environmental labs discharge to the WC System as well. Further discussion of this
waste stream is provided in the Island Industrial Waste section.
The lab sinks in the Island Technical Services Center (TSC), building 7406, drain to CMUD.
There are signs on all of the TSC lab sinks telling lab personnel not to dispose of any chemicals
down the lab sink drains. There is very little chemical use in those labs. The TSC labs perform
weight calibration, and sound and vibration analysis.
There are four steam generators (SG) per unit at McGuire for a total of eight steam generators.
Each has an operating volume of 16,000 gallons. Each unit is provided with a Steam Generator
]lowdown Recycle System. Steam generator blowdown is continuous at a rate of approximately
200 gallons per minute per unit. The blowdown is directed to either the condensate polishing
de ineralizers or to the steam generator blowdown demineralizers. If the blowdown water
quality is unacceptable, it is rejected. Rejected water is discharged to the WC System or to the
WM System depending on lever of radioactivity.
During normal operation, hydrazine is added to the condensate system for oxygen scavenging.
The hydrazine concentration is maintained within a range of -00 ppb.
3-methoxypropylamine is added for pH control. The steam generators and he ell are placed in
wet lay-up if a. unit is to be in extended shutdown or per management direction. Each unit is
normally shutdown every 12 — 18 months for refueling and maintenance.
Dispersants may be used in the plants Steam Generators to control corrosion and sediment
buildup, therefore the potential exists that rejected blowdown waste waster may contain small
amounts of the dispersant.

Groundwater Drainaae System
The Groundwater Drainage System (WZ) is designed to relieve hydrostatic pressure from the
Reactor and Auxiliary Buildings by discharging groundwater collected in sumps to either a yard
drain or the TBS. There are three groundwater sumps with two 250 GPM sump pumps each.
Two of the sumps discharge to the TBS while the third sump discharges to a yard drain that is
routed to the Standby Nuclear Service Water Pond (SNSWP):
C Svstem Unwaterin
The RC System for each of the two units has a volume of approximately 2 million gallons.
During refueling outages and periodically during other shutdowns, the'RC System must b
unwatered, This water is essentially untreated lame water. The principle unatering discharge
route is through the WWCB, but it can be routed through the WC System for short periods of
time. See additional details under Outfall 005,

Miscellaneous S stem/Com orient Cleaning
Other systems/components (such as strainers, HVAC heat exchangers, etc.) are cleaned
periodically because of scaling or plugging. Other components are cleaned as necessary for
various fouling problems. Solutions utilized are dilute acids or caustics. Typically only small
volumes of waste are generated Chemicals utilized by these methodologies, alone or in
combination, mayinclude the following:

UTFALL 004
utfall 004 discharges wastewater from the Radwaste Liquid Waste Monitoring System (WM).
This discharge combines with RC water before discharging through the concrete discharge
structure (Dutfall 001) into Lake Norman as a batch discharge. All radioactive and potentially
radioactive liquids are collected, segregated and Processed prior to release. These effluents are
classified as recyclable or non -recyclable liquids. Recyclable liquids are recirculated back to
their Process streams. Non -recyclable liquids are collected and processed to Nuclear Regulatory
Commission (NRC) requirements Per 10 CFR Part 20 and 10 CFR Part 50 requirements Prior to
release. The type of processing depends on the type of waste. The maximum discharge rate
from WM is 120 GPM. The batch discharge flow for a Waste Monitor Tank Release is a
function of activity level, the number of RC pumps in operation, and the resultant boron
concentration in Lake Norman.
The WM collects waste in three subsystems; floor and equipment drains, laundry waste, and
ventilation unit drains. Chemicals that may be present in the WM System include:
boric acid

typical commercial products used to clean and maintain the floors as well as closed cooling
corrosion inhibitors and microbicides from leakage/drainage of the HVAC Systems. The
corrosion inhibitors may contain nitrite, borate, carbonate, triazole, azle, and glycol compounds.
.Additionally, HVAC cooling units are periodically cleaned using dilute coil cleaning solutions.

SLUDGE MANAGEMENT PLAN
Conventional Waste Water System sludge is disposed of in the site's permitted landfill.
The landfill is a Subtitle D Solid Waste Lined Landfill which only accepts non-
hazardous waste. Prior to disposal, the sludge is sampled, then removed and e-watered.
The source of the site's sludge is its filtered water system which is used to provide ultra
high purity system water to the plant. This system uses Diatomaceous Earth (DE)
pressure filters. The filters are bacwashed and the DE is collected in the Initial Hold. -up
Pend with some residual ending up in our waste water treatment ponds. The DE must b
removed approximately every 24 months from the Initial Holdup Pond.-
Other sources of sludge are accumulation of dusts and silts from plant operation and the
areas surrounding the ponds.
Sourcesof radioactivity in the sludge come from various sumps in the auxiliary and
turbine buildings.

DISCUSSION OF ANALYSIS PERFORMED AND RESULTS
OBTAINED
Outfall 001 Comments
• GC/MS fraction — base neutral/acid compounds failed surrogate recoveries on the
initial sample (5/13/09). The outfall was resampled on 6/17/09 and all surrogates
passed. No compounds were detected in either sample. The laboratory Control
Standard for the first sampling event (5/13/09) failed QC recovery requirements for 2
Chloronaphthalene 53% (QC limits 60-118%) and acenaphthene 56% (QC limits 60 -
132%. The Laboratory Control Standard for the second sampling event (6/17/09) failed
QC recovery limits for benzidine < 1% (QC limits 1-150%). The data should be
considered valid as the sample was resampled and all surrogates passed as well as all
LCS compounds except benzidine. This compound is very unstable as noted by the large
acceptance limits.
• Sulfite results should be considered estimates as the 15 minute holding time was not
met.

- :Aquatic Invertebrate-EC50
TOLERANCES
- Currently, use of rotenone or derris or cube roots on growing crops is
exempt from the requirement of tolerances, and neither tolerances nor
exemptions exist for rotenone residues in animal commodities,
4. SUMMARY OF REGULATORY POSITION
Rotenone is not being referred to Special Review because none of
criteria for special review were met.
Cranberry and piscicide uses are classified for restricted use. Users
mint consult their State Fish and. Game Agency before applying rotenone
products. Because of significant data gaps on the effects of rotenone in
upland game birds, waterfowl, estuarine and marine organisms, a
statement is required on all end -use products giving directions for use
for killing fish.- The statement requires mandatary consultation with
state or federal fish and wildlife agencies and will minimize effects on
non -target organisms.
The Agency is concerned about residues and metabolites of rotenone
and associated resins in/on plants and animals. Data on the metabolism
and nature of rotenone residues are needed to reevaluate the tolerance
exemption.
Water treated with rotenone must not be used as potable water or for
irrigation of crops. A restriction against use of rotenone within one
half mile of potable water or irrigation intakes must be included on
labels of products intended for use in cranberry bogs and for control of
fish. This statement will be an :interim precaution until data on
residues in water are available.

6. LABELING REQUIREMENTS
Products containing rotenone intended or terrestrial (food and non-
food) and domestic outdoor uses must include the following statement on
the label:
"This pesticide is toxic to fish.. Do not apply directly to water
or wetlands (swamps, bogs, marshes, potholes). Runoff and drift
from treatedareasmay be hazardous to aquatic organisms in
adjacent sites. Do not contaminate untreated water when disposing
of equipment washwater:"
Products containing rotenone intended or use in cranberry bogs must
include the following statement on the label:
"This pesticide is toxic to fish. Runoff and drift from treated
areas may be hazardous to aquatic organisms in adjacent sites. Do
not contaminate untreated water when disposing of equipment
washwaters.'
Products containing rotenone intended for use to kill fish must
include the following statement on the label:
"This pesticide is toxic to fish. Fishkills are expected at
recommended rates. Consult your State Fish and Game Agency before
applying this product to public waters to determine if a permit
is needed for such an application. Do not contaminate untreated

EXECUTIVE SUMMARY
In accordance with National Pollutant Discharge Elimination System DE) pennit
number NCO024392 for McGuire Nuclear Station ( S), the Lake Norman Maintenance
Monitoring Program continued during 2007. Overall, no obvious long-term impacts o
station operationswere observed in water quality or phytoplankton, zooplankton, and fish
communities, The 2007 station operation data are summarized and continue to demonstrate
compliance with thermal limits and cool water requirements.
The monthly average capacity factors for MNS in 2007 were 101.9, 101.4, and 101.6%
during July, August, and September, respectively. The average monthly discharge
temperature was 97.2 °F 3. °C) for July, 98.8 °F (37.1 °C) for August, and 97.9 °F (36.6
°C) for September 2007, below the 99.0 °F (37.2 °C) thermal limit for these months. The
volume of cool water in Lake Norman in 2007 was adequate to comply with both the Nuclear
Regulatory Commission Technical Specification requirements and the NPDES discharge
water temperature limits. Annual precipitation in the vicinity of MNS in 2007 totaled 78.2
cm and was the third lowest measurement reported over the period 1975 — 2007, with lower
values being recorded only in 1981 (6.4 cm) and 1986 (76.5 m). Air temperatures near the
S in 2007 were warmer than bath 2006 and the long-term mean for the months of March,
.August, September, and October.
Temporal and spatial trends in water temperature and DO in 2007 were similar to those
observed historically, and all data were within the range of previously measured values.
Water temperatures in 2007 for the months of January, March, and April ranged from 0.1 to
3.8 °C warmer than measured in 2006 in both the mixing and background zones, whereas
007 February temperatures were as ;much as 2.2 °C cooler than observed in 2006. These
interannual differences in water temperatures paralleled differences exhibited in monthly air
temperature data, but with about a one -month lag. Reduced operations of Unit ] at MNS in
March and April 2007 also contributed to these interannual differences during the winter and
early spring.
Summer water temperatures in 2007 were generally similar to those observed in 206 in loth
zones, with one notable exception. Surface water temperatures in the mixing zone in June
2007 were up to 2.7 °C cooler than observed in 2006, and appeared to be related primarily to
reduced operations of Unit 1 rather than to interannual differences in air temperature. Late
summer, fall, and early winter water temperatures in 2007 were consistently warmer in both

zones than those measured in 2006, and followed the trend exhibited in air temperatures. The
most striking differences were observed in the mixing zone in November when 2007
temperatures were as much as 4.4 °C warmer than measured in 2006. Temperatures at the
discharge location in 2007 were generally similar to 2006 and historical data. Temperatures
in 2007 were slightly cooler in the spring, and warmer in the fall than observed in 2006. The
wan -nest discharge temperature of 2007 at Location 4 (37.8 °C) occurred in September and
was identical to the maximum measured in 2006.
Seasonal and spatial patterns of DO in 2007 were reflective of the patterns exhibited for
temperature; i.e., generally similar in both the mixing and background zones. Winter and
spring DO values in 2007 were either equal to or slightly lower, in both the background and
mixing zones, than measured : in 2006 and appeared to be related predominantly to the
differences in water column temperatures in 2007 versus 2006 Summer DO values in 2007
were highly variable throughout the water column in both the mixing and background zones
ranging from highs of 6.0 to 8.4mg/L in surface waters to lows of 0.0 to 2.0mg/L in bottom
waters. This pattern is similar to that measured in 2006 and earlier years. All dissolved
oxygen values recorded in 2007 during this period were within the historical range.
Considerable differences; were observed between 2007 and 2006 late summer and fall DO
values in both the mixing and background zone, especially in the metalimnion and
hypolimnion during the months of September, October, and November. The 2007 late
summer and autumn DO data indicated that fall convective reaeration proceeded slower and
was less complete throughout the water column than observed in the corresponding months
in 2006. Consequently, 2007 DO levels in either a portion or all of the water column were
less than observed in 2006. The seasonal pattern of D4 in 2007 at the discharge location was
similar to that measured historically, with the highest values observed during the winter and
lowest observed in the summer and early fall. Fall DO levels in 2007 at Location 4.0 were
slightly lower than observed in 206 due to warmer temperatures. The lowest DSO
concentration measured at the discharge location in 200 (5.5 mg/L) occurred in September
and was identical to that measured in August, 2006; it was also 1.4 mg/L higher than the
historical minimum measured in August 2003 (4. mg/L);
Reservoir -wide isotherm d isopleth information for 2007, coupled with 'heat content and
hypolinmetic oxygen data, illustrated that Lake Norman exhibited thermal and oxygen
dynamics characteristic of historical conditions and similar to other Southeastern reservoirs
of comparable size, depth, flow conditions, and trophic status. Suitable pelagic habitat
conditions for adult striped bass in 207 were most recently similar to conditions measured in

06 when habitat elimination was observed for a period of about 50 to 60 days during the
summer. Observed striped bass mortalities in 2007 totaled thirteen fish.
All chemical parameters measured in 2007 were similar to 2006 and within the concentration
ranges previously reported for the lake during both preoperational and operational years of
S. Specific conductance and nutrient values and all concentrations of cations and anions
were tow. Concentrations of metals were also low and often below analytical reporting'
limits. All values reported for cadmium, lead, zinc, and copper in 2007 were below the State
water ,quality standard or action level for each of these metals. Manganese and iron
concentrations in the surface and bottom waters were generally low in 2007, except during
summer and fall when bottom waters became anoxic, thereby creating a chemical
environment conducive for the release of these species into the water column. Only one iron
value recorded in the bottom waters at Location 5.0 in August, exceeded the State action
level of 1.0 mg/L. Manganese levels, however, exceeded the State action level 0 µg/L) in
the bottom waters at various locations throughout the lake in the summer and fall, This
phenomenon, i.e., -the release of iron and manganese from bottom sediments into the water
column, in response to law oxygen levels, is common n in stratified waterbodies.
Chlorophyll concentrations were generally within historical ranges during 2007. Several
record low chlorophyll concentrations were recorded in November. Lake -wide mean
chlorophyll increased ftom, February through August, then declined to the annual minimum
in November. Maximum chlorophyll concentrations were typically observedup-lake at
Location 69.0, while minimum chlorophyll concentrations were recorded from down -lake at
Locations 20 through 9.5. The highest chlorophyll value in 2007 (1. µg/L) was well
below the NC State Water Quality standard f 40 g/L.
Phytoplankton densities and biovolu ` es were generally higher in 2007 than in 2006. Higher
standing crops were usually observed at up -lake locations, while lower values were noted
down -lake. Standing crop values were lower than the NC guidelines for algae blooms
Seston dry and ash -free weights were most often lower in 207 than in 2006. Down -lake to
up -lake differences were apparent during all quarters. Maximum dry and ash -free weights
were generally observed at Location 69.0, while minimum values occurred at Locations 2.
through 8.0.
vii

ecchi depths reflected suspended solids, with shallow depths related to high dry weights.
The lake -wide mean sechi depth was slightly higher in 2007 than in 2006 and within
historical ranges observed since 1992.
Diversity of phytoplankton taxa in 2007 was the highest recorded since the beginning of this
monitoring program. The taxonomic composition during 2007 was similar to many previous
years. Cryptophytes were dominant in February, while diatoms were dominant during May
d November. Green algae were dominant during August. Blue-green algae were slightly
ore abundant in 2007 than in 2006, however, their contribution to total densities was rarely"
over 3%.
e cryptophyte Rhod monas rninuta was the most abundant alga each year of the Lake
Norman Maintenance Monitoring Program: The diatom Fragillar°ia cr otonensis was the
most abundant diatom in May, while Tabellar°ia fen strata and Melosira arnbigua were
dominant in November. The small des id, C smar°iurn asphearosporum var. str°iggosum was
dominant in August 2007. These taxa have been common and abundant throughout the
program.
Maximum zooplankton densities occurred most often in the spring of 2007. Minimum
oopl nkton densities were generally noted in the fall. Epilinmetic densities were higher than
whole -column densities as in, previous years. Mean zooplankton densities were usually
higher among background locations than among mixing zone locations in 2007. Spatial
trends of zooplankton population densities increased from down -lake to up -lake locations.
year-to-year -spring trend of increasing zooplankton densities among mixing zone locations
was observed from around 1997 through 2005. Densities at these locations declined sharply
in 2006 followed by an increase in 2007. Long-term trends showed much higher year-to-year
variability at background locations than at mixing zone locations.
Epilinmetic zooplankton densities were generally within the ranges of densities observed in
previous years. Record high densities were observed during winter at Location 1.9 and
summer at Location 9.5.
Since the Lake Norman Maintenance Monitoring Program began in 1987, 123 zooplankton
taxa have been observed in samples. Of these, 49 were identified in 2007. Additionally; two
previously unreported taxa, were identified during 2007.

Overall relative abundance of copepods decreased from 2006 to 2007. Copepods were
dominant in only three samples. Cladocerans were dominant in two samples and rotifers
were dominant in all other samples. The relative abundance of microcrustaceans increased
slightly in the epilimnion of the mixing zone, although they decreased among whole -column
samples since 2006. At background locations, relative abundances of microcrustaceans i
007 were similar to those of 2006. Historically, copepods and rotifers have most often
shown annual peaks in the spring, while cladocerans continued to demonstrate year-to-year
variability.
Copepods were dominated by immature forms. Adults rarely accounted for more than % o
zooplankton densities. As in previous years, the most important adult copepod was
'ropvcycl ps. Bosmina was the dominant cladoceran as in most previous years of the
program. B sminopsis dominated several cladoceran populations during the summer. The
most abundant rotifers observed in 2007 as in many previous years, were Plyarthra,
Kerataella, and Ptyg ra. Conochilus, Asplanchna, and Syncheata were also important among
rotifer populations;
In accordance with the Lake Norman Maintenance Monitoring Program fish monitoring
programs continued during 2007. Spring elctrofihing indicated that numbers and biomass
of fish in 2007 were generally similar to those noted since 1993. Additionally, electrofishin
indicated that 12 to 20 fish species and two hybrid complexes ;comprised fish populations i
the three sampling areas. Largemouth bass numbers and biomass continue to decline, and the
2007 numbers and biomass were some of the lowest recorded since sampling began in 1993.
While displacement of largemouth bass since the introduction of spotted bass in the lower
lake is apparent, the direct effect on largemouth bass recruitment is indeterminate, possibly
due to confounding effects of ether introductions including alewife and white perch. During
2007, the number of summer striped bass mortalities (13) and winter mean relative weight
(79.5) were similar to those of previous years. Hydroacoustic sampling estimated the 2007
forage fish population at approximately 72 million. This is comparable to previous years.
After an increase in 2006, purse seine sampling indicated a decrease in the percentage of
alewives in 2007 to the lowest percent composition since their 199 introduction. Thrafin
shad lengths remained at pre -alewife introduction sizes.
Lake Norman Maintenance Monitoring results from 27 are consistent with results from
previous years. No obvious short-term or long-term impacts were observed in water quality
or biota of Lake Norman.

CHAPTER 1
MCGUIRE NUCLEARSTATION
INTRODUCTION
The fallowing annual report was prepared for the McGuire Nuclear Station S) National
Pollutant Discharge Elimination. System DES) permit # NC0024392 . issued by North
Carolina Department of Enviromnent and Natural Resources (NODE ). This report
summarizes environmental monitoring of Lake Norman during 2007
OPERATIONAL DATA FOR 2007
Station operational data for 2007 are listed in Table '1-1. Operational maintenancewas
performed on Unit`I during the period March — April. The monthly average capacity factors
for MNS were 101.9, 101.4, and 101.6% during July, August, and September, respectively.
These are the months when conservation of cool water is most critical and compliance with
discharge temperatures is most challenging. These three months are also when the thermal
limit for MNS increases from a monthly average of 95.0 'F (35.0 °C) to 9.0 °F (37. °C).
The average monthly discharge temperature was 97.2 °F (36.2 °C) for July, 98.8 °F (371 °C)
for August, and 9.9 °F (36.6 °C) for September 2007, The volume of cool water in Lake
Norman was tracked throughout the year to ensure that an adequate volume was available to
comply with both the Nuclear Regulatory Commission Technical Specification requirements
and the NPDES discharge water temperature limits.

CHAPTER 2
WATER CHEMISTRY
INTRODUCTION
The objectives of the water chemistry portion of the MNS NPDES Maintenance Monitoring
Program are to:
1. maintain continuity in the chemical data base of Lake Norman to allow detection of
any substantial station -induced and/or natural change in the physicochemical structure
ofthelake;and
2. compare, where applicable, these physicochemical data to similar data in other
hydropower reservoirs and cooling impoundments in the Southeast.
This report focuses primarily on 2006 and 2007. Where appropriate, reference to pre-2006
data will be made by citing reports previously submitted to the N;IENR.
METHODS AND MATERLAIS
The complete water chemistry monitoring program for 2007, including specific variables,
locations, depths, and frequencies is outlined. in Table 2-1. Sampling locations are identified.
in Figure 2-1. Measurements oftemperature, dissolved oxygen >), DO saturation, pH and
specific conductance were taken, in sitar, at each location with a Hydrolab Data -Sande
(Hydrolab 2006) starting at the lake surface (0. ) and continuing at one -meter intervals to
lake bottom, Pre- and post -calibration procedures associated with operation of the Hydrolab
were strictly followed, and documented in hard -copy fortnat. Hydrolab data were captured
and stored electronically, and following data validation, converted to spreadsheet format for
archive:
Water samples for laboratory analysis were collected with a Kemmerer or Van Dom water
bottle at the surface (0. ), and from one meter above bottom, where specified (Table 2-1).
Samples not requiring filtration were placed directly in single -use polyethylene terephtalate
2-1

(PET) bottles which were rinsed in the field with lake water just prier to obtaining a sample.
Samples requiring acidification, but no filtration, were placed directly in pre -acidified high
density polyethylene PE) battles. Samples requiring filtration were first processed in the
field by filtering through a 0.45-lun filter (Gelman AquaPrep, 600 Series Capsule) which was
rinsed with 500 mL of sample water, and then placed in pre -acidified HDPE bottles (Table -
1). Upon collection, all water samples were immediately stored in the Clark, and on ice, to
minimize the possibility of physical, chemical, or microbial transformation.
Analytical methods, reporting :limits and sample preservation techniques employed were
identical to those used in 2006, and are summarized in Table _2. All laboratory water
quality analyses were performed by the Duke Energy analytical laboratory located in
Tuntersville, NC. This laboratory is certified to perform analytical assessments for inorganic
d organic parameters in North Carolina (North Carolina DWQ Laboratory Certification
program, certificate number 248), South Carolina (SouthCarolina Department of Health and
Enviromnental Control, certificate number 99005), and New York (New York Department of
Health, certificate number 11717).
comprehensive Quality Assurance/Quality Control Program (QAIQCP) is fundamental to
the collection, reporting, and interpretation of waster duality data, and :most investigators
implement some type of QAtQCP to identify, quantify, and document bias and variability in
data resulting from the collection, processing, shipping, handling and analysis of samples by
field and laboratory personnel. Both the United States Environmental Protection Agency
U EPA 1998a, b) and the united States Geological Survey (USGS 1998, 2002) require: that
any agency-flinded project have an approved quality assurance program, and that this
program incorporate both a field and laboratory component. USGS also requires that any
agency funded study that includes laboratory assessments ust also participate in their
Standard Reference Program (S ). This program was originally developed. by USGS in the
1960"s and currently involves analysis by participating laboratories of standards (Blind
unknowns) created by the agency on a biannual schedule (USGS 2002).
The QAIQCP employed for this study followed the recommendation of the USEPA and
USGS, and included both a field and laboratory component. Field blanks, i.e. Milli-Q water
placed in sample bottles, were subjected to the same sample collection and handling
procedures, including filtration; applied to actual samples. Periodically, samples were also
split prior to submitting to the laboratory for analysis with the goal of quantifying intra_
sample analytical variability. The Laboratory QAIQCP involved a variety of techniques
2-2

commonly used in analytical chemistry and included reagent blanks, spikes, replicates, and
performance samples. To supplement this program, additional performance samples were
run on the major inns and nutrients. Beginning in 2005, standards were purchased from the
USGS through the agency's SRS program, and submitted biannually to Duke's laboratory t
serve as a "double blind" assessment of analytical performance. These standards allowed
quantification of the uncertainty of the analytical results against known values that were
within the same concentration matrix as actual samples. The goal of this effort is to assemble
analytical uncertainty data for chemical analytes which can be incorporated into statistical
analyses assessing trends in time or space.
Water quality data were subjected to various graphical and statistical techniques in an attempt
to describe spatial and temporal trends within the lake, and interrelationships among;
constituents. Whenever analytical results were reported to be equal to or less than the
method reporting limit, these values were set equal to the reporting limit for statistical
purposes. Data were analyzed using two approaches, 'both of which were consistent with
earlier Duke Power Company, Duke Power, and Dube Energy studies on the lake (puke
Power Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke
Power 1997 1998, 1999, 2000, 2001, 2002, 2003, 2004a, 2005; and Duke Energy 2006,
2007) The first method involved partitioning the reservoir into mixing, background, and
discharge zones, consolidating the data into these sub -sets, and making comparisons among
zones and years. In this report, the discharge includes only Location 4; the mixing .zone,
Locations 1 and 5 the background zone includes Locations 8, 11, and 1 (Figure 2-1). The
second approach., applied primarily to the in situ data, emphasized ` a much broader lake -wide'
investigation and encompassed the plotting of monthly isotherms and isopleths, and summer
striped bass habitat. Several quantitative calculations were also performed on the in situ data.;
these included the calculation of the areal hypolimnetic oxygen deficit CAD), maximum
whole -water column and hypoli nion oxygen content, maximum whole -water column and
hypolimnion heat content, mean epii pion and hypolimnion heating rates over the stratified
period; and the Birgean heat budget.
Heat content (Kcal/cm), oxygen content (mg/cm), d mean oxygen concentration ( g/L

Precipitation and air temperature data were obtained from :meteorological monitoring site
established. near MNS in 1975. These data are employed` principally by Duke Energy as input
variables into meteorological modeling studies as required by the Nuclear Regulatory
Commission to address safety issues associated with potential radiological releases into the
atmosphere y MNS (Duke Power 2004b). The data also serve to document localized
temporal trends in air temperatures and rainfall patterns. Data on lake level and hydroelectric
flows were obtained from Duke Energy -Carolinas Fossil/Hydro Generation, which monitors
these metrics hourly:

26.8 cm less than observed in 2006 (1.0 cm), and 39.4 cm less than the long-term
precipitation average for this area (117.6 cm), based on Charlotte, NC airport data. Annual
precipitationtotals for 2007 measured at the MNS site were also the third lowest over the
period' 1975 — 2007 with lower values being recorded only in 1981 (64; 4 cm) and 1986
(76.5 cm). Monthly rainfall in 2007 was greatest in March with 10.57 cm, and the least in
November with 1.98 cm.
Duke Energy reported that air temperatures near the McGuire Nuclear Station in 2007 were
generally warmer than the long-term mean, based on monthly average data (Duke Energy
2006). Monthly mean air temperatures in 2007 near the nuclear facility were warmer than
both 2006 and the long-term mean for the months of March., August, September and October
(Figure 2-). The temporal differences were most pronounced in September and October
2-4

2007 when temperatures averaged 2.8 and 4.1 'C warmer, respectively, than recorded in
2006.
Tem erature and Dissolved O&y en
Watertemperatures measured in 2007 illustrated similar temporal and spatial trends in the
background and mixing zones (Figures 2-3 and -4), as they did in 2006. This similarity in
temperature patterns between zones has been a dominant feature of the thermal regime in
Lake Norman since MNS began operations in 1983. When between -zone differences in
temperatures are observed, they occur predominately during the cooling period, and can b
traced to the influence of the thermal discharge at MNS. Additionally, interannual
differences in water temperatures in Lake Norman, particularly in surface waters in the
background zone, typically parallel differences in air temperatures but with a one -month lag
time (Duke Power 2002, 2003, 2004a, 2005; Duke Energy 2006, 2007).
Water temperatures in 2007 for the months of January, March, and April ranged from 0.1 to
3.8 OC warmer than measured in 2006 whereas 2007 February temperatures were as much as
2.2 °C cooler than observed in 2006 (Figures 2-3 and 2-4). These interannual differences in
water temperatures paralleled differences in air temperatures (Figure 2-2c) but because lake
sampling is generally performed in the first week of each month, the observed data reflects
the cumulative influences of meteorology and hydrology during the previous month,
Reduced operations of Unit l in March 2007 (Table 1-1) undoubtedly also contributed to
slightly cooler temperatures in April 2007. Minimum water temperatures in 2007 were
recorded in early February and ranged from 7.5 °C to 10.8 °C in the background zone and
from 8.0 'C to 13.1 °C in the mixing zone.Minimum water temperatures measured in 2007
were within the observed historical range Duke Power Company 1985, 1987, 1988, 1989,
1990, 1991,_ 1992,1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999, 2000, 2001, 2002,

Late -summer, fall and early winter water temperatures (September, October, November, and
December) in 2007 were consistently warmer in bath zones than those measured in 2006 and
followed the trend exhibited in air temperatures (Figures 2- c, 2-3). The most striking
differences were observed in the mixing zone in November when 2007 temperatures were as
much as 4.4 °C warmer than measured in 2006. Interannual differences in December'
temperature profiles were minimal.
Temperatures at the discharge location in 2007 were generally similar to 2006 (Figure 2-
a,nd historical data (Duke Power Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993,
1994, 1995, 1996 Duke Power 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004a, 2005
Duke Energy 2006, 2007). Temperatures in 2007 were slightly cooler in the spring (March
temperatures were taken during a station outage, and warmer in the fall, than observed in
2006, The warmest discharge temperature of 2007 at Location 4 (37.8 °C) occurred in
September and was identical to the maximum measured in 2006.
Seasonal and spatial patterns of DO in 2007 were reflective of the patterns exhibited for
temperature, i.e., generally similar in both the mixing and background zones (Figures 2-6 and
-7). As observed with water column temperatures, this similarity in DO patterns between
zones has been a dominant feature of the oxygen regime in Lake Norman since MNS began
operations in 1983.
Winter and spring DO values in 2007 were generally equal to or slightly lower, in berth the
background and mixing zones, than measured in 2006, except in February when 2007; DO
values ranged from 0.4 to 1.2 mg/L higher than in 2006 (Figures 2-6 and -a7). The
interannual differences in DO values measured during this period appear to be related
predominantly to the differences in water column temperatures in 2007 versus 2006. Warmer
water would be expected to exhibit a lesser oxygen content because of the direct effect of
temperature on oxygen solubility, which is an inverse relationship, and indirectly via a
restricted convective mixing regime which would limit water column reaeration. Conversely,
cooler water column temperatures,' as measured in February 2007, would be expected to
exhibit higher oxygen values because of increased oxygen solubility, and an enhanced
convective mixing regime which would promote water column reaeration.
Summer DO values in 2007variable throughout the watere both
backgroundmixing and • of ! to
lows of 0.0 to 2.0 mg/L in bottom waters. This pattern is similar to that measured in 2006
-

and earlier years (Duke Power Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993,
1994, 1995, 1996 Duke Power 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004a, 2005
Duke Energy 2006, 2007). Unlike most Previous years, summer DO profiles in 2007 and
2006 were remarkably similar throughout the water column in both zones, suggesting that
those physical and metabolic processes that influence DO within the reservoir were
proceeding at about the same rates in 2007 and 2006. All dissolved oxygen values recorded
in 2007 during this period were within the historical range.
Considerable differences were observed between 2007 and 2006 late summer and fall TAU
values in bath the mixing and background zone, especially in the metalimnion and
hypolimnion during the months of September, October, and November (Figures 2-6 and. 2-7).
These interannual differences in DO levels during the cooling season are common in
Catawba River reservoirs and can be explained by the effects of variable weather patterns on
water column cooling (heat loss) rates and mixing. Warmer air temperatures delay water
column cooling which, in turn, delays the onset of convective mixing of the water column
and the resultant reaeration of the metalimnion and hypohmnion. Conversely, cooler air
temperatures increase the rate and magnitude of water column heat loss, thereby promoting
convective mixing and resulting in higher DO values earlier in the year.
The 2007 late summer and autumn 4 data indicate that fall convective reaeration proceeded
slower and was less complete throughout the water column than observed in corresponding
months in 2006. Consequently, 2007 IBC} levels in either a portion or all of the water were
less than observed in 2006. These between -year differences in DO corresponded strongly
with the degree of thermal stratification which, as discussed earlier, correlated with
interannual differences in air temperatures (Figures : 2-2 2-3, ,and -4). Interannual
differences in DO patterns are common not only within the Catawba River Basin, but
throughout Southeastern reservoirs and can reflect yearly differences in hydrologic,
meteorologic, and li nologic forcing variables (Carle and Hannan 1985; Petts, 1984).
The seasonal pattern of DO in 2007'at the discharge location was similar to that measured
historically, with the highest values observed during the winter and lowest observed in the
summer and early fall (Figure 2-5). fall DO levels in 2007 at location 4.0 were slightly lower
than observed in 2006 clue to warmer temperatures. The lowest DO concentration measured
at the discharge location in 2007 (5.5 mg/L) occurred in September, and was identical to that
measured in August, 2006; it was also 1.4 mg/L higher than the historical minimum,
measured in August 2003 (.mg/L).

Reservoir -Wide Temnerature and Dissolved Oxvizen
The monthly reservoir -wide temperature and DO data for 2007 are presented in Figures 2-8
and 2-9. These data are similar to that observed in previous years and are characteristic of
cooling impoundments and hydropower reservoirs in the Southeast (Cole and Hannan 1985;
Hannan et al. 1979; Petty 1984). Detailed discussions on the seasonal and spatial dynamics
of temperature and dissolved oxygen during both the cooling'and heating periods in Lake
Norman have been presented previously (Duke Power Company 1992, 1993, 1994, 1995,
1996).
The seasonal heat content of both the entire water column and the hypolimnion for Lake
Norman in 2007 are presented in Figure 2-10a; additional information on the thermal regime
in the reservoir for the years 2006 and 2007 is presented in Table 2-3. Annual minimum heat
content for the entire water column in 2007 (8.88 Kcal/cm; 8.92 'C) occurred in early
February, whereas the maximum heat content (28.79 Kcal/cm�; 28.98 -C) occurred in late
August. Heat content of the hypolimnion exhibited a somewhat different temporal trend as
that observed for the entire water column. Annual minimum hypolinmetic heat content also
occurred in early February and measured 4.77 Kcal/CM2 (7.53 'Q, but the maximum
occurred in. early September and measured 1.5.77 Kcal/crn' (25.04 -Q. Heating of both the
entire water column and the hypolimnion occurred at approximately a linear rate from
minimum to maximum heat content, The can heating rate of the epilimmon equaled 0,110
'C/day and 0,089 'C/day for the hypolimnion; both rates were slightly greater than observed
in 2006 (Table 2-3). The 2007 heat content and heating rate data for Lake Norman were
generally similar to that observed in previous years (Duke Power Company 1985, 1987,
1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999, 2000,
2001, 2002, 2003, 2004a, 2005; Duke Energy 2006, 2007).
The seasonal oxygen content and percent saturation of the whole water column, and the
hypolininion, are depicted for 2007 in Figure 2-10b. Additional oxygen data can be found in
Table 2-4 which presents the 2006 AHOD for Lake Norman and similar earlier estimates for
18 Tennessee Valley Authority (TVA) reservoirs, Reservoir oxygen content was greatest in
mid -winter when DO content measured 10.4 mg/L for the whole water column and 10.3
mg/L for the hypolimnion. Percent saturation values at this time approached 90% for the
entire water column and 86% for the hypolimnion. Beginning in early spring, oxygen content
began to decline precipitously in both the whole water column and the hypolimnion, and
continued to decline linearly until reaching a minimum in late summer. Minimum summer
2-8

volume -weighted DO values for the entire water column measured 3.9 ,g/L (52%
saturation), whereas the minimum for the hypolimnion was 0.1 g/L (2.2% saturation).
The mean rate of DO decline in the hypolimnion over the stratified period, i.e., the AHOD,
was 0039 mg/c a/day (0.061 g/L/day) (Figure 2-10b), and is similar to that measured in
2006 (Duke Energy 2007).
Hutchinson (1938, 1957) proposed that the decreaseof DO in the hypolimmon of a
aterboy should be related to the productivity of the tropogenic zone. Mortimer (941
adopted a similar perspective and proposed the following criteria for .AHODs associated with
various trophic states, oligotrophic < 0.025 mg/cm/day, mesotrophc 0.026 mg/c /day to
0.054 mg/cm2/day, and eutrophic 0.05 g/cm�/day. Employing these limits, Lake
Norman should be classified as mesotrophic based on the calculated AHOD value of 0.039
mg/c ; 2/day for 2007. The oxygen -based mesotrophic; classification agrees well with the
esotrophic classification based on chlorophyll a levels (Chapter 3). ;The 2007 AHOD value
is also <similar to that found in other Southeastern reservoirs of comparable depth, chlorophyll
ca status, and Secchi depth. (Table -4),
Striped Bass Habitat
Suitable pelagic habitat for adult sniped bass, defined as that layer of water with temperatures
26 °C and DO levels > 2.0 xrag/L, was found lake -wide from id September 2006 through
early July 2007. Beginning in late June 2007, habitat reduction proceeded rapidly throughout
the reservoir both as a result of deepening of the 26 °C isotherm and metalinmetic and
hypolimnetic deoxygenation (:Figure -11). Habitat reduction was most severe from mid July'
through early September when no suitable habitat was observed in the reservoir. These
conditions were similar to those observed in most previous gears except that in 2007 no
habitat existed in the upper, riverine segments of the reservoir. Historically, a small, but
spatially variable zone of habitat is typically observed near and upstream of the confluence of
Lyles Creek with Lake Norman, Habitat measured in the upper reaches of the reservoir
appears to be influenced by bath inflow from Lyles Creek and discharges from Lookout
Shoals Hydroelectric facility, which generally are somewhat cooler than ambient conditions
in Labe Norman. Upon entering Lake Norman, this water mixes with ambient waters and
then proceeds as a subsurface underflow as it migrates dow "ver (Ford 1955).
An additional refuge was also observed in the metalimnion and hypolimnion near the Cowans
Ford dam during this period, but this lasted only until 23 July when dissolved oxygen was
2-9

reduced to < 2.0 lL by microbial demands, thereby eliminating suitable habitat in the
lower portion of the reservoir, Summer -time habitat conditions for adult striped bass in 2007
were more severe than 2004 when the lamest striped bass die -off ever was observed in the
reservoir (2610 fish). Conditions in 2007 were most recently similar to those measured in
2006 when habitat elimination was observed for a period of about 50 to 60 days. Observed
striped bass mortalities in 2007 totaled thirteen fish (Chapter 5).
Physicochemical habitat expanded appreciably by mid September, primarily as a result of
epilimnion cooling and deepening, and in response to changing meteorological conditions:
The temporal and spatial pattern of striped bass habitat expansion and reduction observed in
2007 was generally similar to that previously reported in Labe Norman, and many other
Southeastern reservoirs (Coutant 1985; Matthews et al. 1985 Duke Power Company 1985,
1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999,
2000, 2001, 2002, 2003, 2004a, 2005 `Duke Energy 2006, 2007).
Turbidity and Specific Conductance
Surface turbidity values were generally low at the MNS discharge, mixing zone, and id -lake
background locations during 2007, ranging from. 0.95 to 5.60 NTU's (Table 2- ). Bottom
turbidity values were also low over the 2007 study period, ranging from 1.0 to 8.4 NTU's
(Table 2-5). Turbidity values observed in 2007 were within the historical range (Duke Power
Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power
1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004a, 2005; Duke Energy 2006, 2007).
Specific conductance in Lake Norman in 2007 ranged from 51 to 105 umho%c , and was
generally similar to that observed in 2006 (Table 2- ), and historically (fluke Power
Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power`
1997,'1998, 1999, 2000, 2001, 2002, 2003, 2004a, 200 Duke Energy 2006, 2007). Specific
conductance values in surface and bottom waters in 2007 were similar throughout the year
except during the period of intense thermal stratification, i.e., :August and November, when
an increase in bottom conductance values was observed at locations within the mixing and
background zones. These increases in bottom conductance values appeared to be related
primarily to the release of soluble iron and manganese from the lake bottom under anoxic
conditions (Table 2-5). This phenomenon is common in both natural lakes and reservoirs
that exhibit extensive hypolimnetic oxygen depletion (Hutchinson 1957, Wetzel 1975), and is
an annually recurring phenomenon in Lake Norman.

Maior Cations and Anions
The concentrations of major ionic species in the MNS discharge, mixing, and mid -lake
background zones are provided in Table 2-5. Lake -wide, the major cations were sodium,
calcium, magnesium, and potassium, whereas the major anions were bicarbonate, sulfate, and
chloride. The overall ionic composition of Lake Norman during 2007 was generally similar
to that reported for 2006 (Table 2-5) and previously (Duke Power Company 1985, 1987,
1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999, 2000,
2001, 2002, 2003, 2004a, 2005; Duke Energy 2006, 2007).
Nutrients
Nutrient concentrations in the discharge, mixing, and mid lake background zones of Lake
Norman for 2006 and 2007 are provided in Table 2-5. Overall, nutrient concentrations in
2007 were well within historical ranges (Duke Power Company 1985, 1987, 1988, 1989,
1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999, 2000, 2001, 2002,
2003, 2004a, 2005; Duke Energy 2006, 2007). Nitrogen and phosphorus levels in 2007 were
low and generally similar to those measured in 2006 (Duke Energy 2006.)Historic total
phosphorus (TP) and ortho-phosphorus (OP) concentrations were typically measured at or
below the analytical reporting limits (ARL) for these constituents, i.e., 5 Ag/L. For total
phosphorus, all 44 samples analyzed in 2007 exceeded the ARL, but most measurements (40
of 44) were :5 1.0 g/L. The maximum TP value reported in 2007 was 114 ltg/L and was
observed at the bottom at Location 2.0. Similarly, almost all measurements of OP (43 of 44)
were recorded as :5 5 gg/L, the ]one exception being a value of 13 gg/L reported at the bottom
2-11

depth at Location 2.0. Nutrients in 2007 were generally somewhat higher uplake than
do lake, but the differences were slight and not statistically significant t (p < 0.05). Spatial
variability in various chemical constituents, especially nutrient concentrations, is common in
long, ' deep reservoirs (Soballe et al. 1992). Nitrite -nitrate and ammonia nitrogen
concentrations were low at all locations sampled in 2007 (Table 2-5), and also were generally
similar to 2006 and historical values (Duke Power Company 1985, 1987, 1988, 1989, 1990,
1991, 1992, 1993, 1994, 1995, 1996; Duke Power 1997, 1998, 1999, 2000, 2001, 2002, 2003,
2004a; 2005 Duke Enemy 2006, 2007).
Metals
Metal concentrations in the discharge, mixing, and inid lake background zones of Labe
Norman for 2007 were similar to those measured in 2006 (Table 2-5) and. historically (Duke
Power Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996; Duke
Power 1997,1998 1999 2000, 2001, 2002 2003 200 a, 2005; Duke Energy 2006, 2007).
Iron concentrations in surface and bottom waterswere; generally low (!� 0.4 g/L) during
2007, the lone exceptions being a 0.82-mg/L value measured in the bottom waters at
Location 2.0 in November, and a 1.26-mg/L value measured at the bottom depth at Location
5.0 in August. This latter value is the only instance in 2007 that an iron measurement
exceeded the North. Carolina water quality action level for iron (1.0 g/L; NCDENR 2004).
Similarly, manganese concentrations in the surface and bottom waters were generally low (
100 µ /L) in 2007, except during the summer and fall when bottom waters were anoxic
(Table 2-5). Manganese concentrations in the bottom waters rose above the State water
quality action level for this constituent (200 gg/L; NCDENR 2004) at various locations
throughout the lake in summer and fall of 2007, and were characteristic of historical
conditions (.nuke Power Company 1985, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994,
1995, '1996 Duke Power 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004a, 2005; Duke
Energy 2006, 2007). This phenomenon, i.e., the release of manganese (and iron) from
bottom sediments in response to low redox conditions (low oxygen levels), is common in
stratified. waterbodies (Stumm and Morgan 1970, Wetzel 1975).
Concentrations of other metals in 2007 were typically low, and often below the analytical
reporting limit for the specific constituent (Table 2- ). These findings are similar to those
observed for earlier years (Duke Power Company 1985, 1987 1988, 1989, 1990, 1991, 1992,
1993, 1994, 1995, 1996 Duke Power 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004a

2005; Duke Energy 2006, 2007). All values for cadmium and lead were reported as either
equal to or below the ARL with the lone exception being a lead value of 3.4 gg/L measured
at the bottom depth at Location 2.0 in February. Zinc values were consistently above the
ARL and ranged from < 1.0 jig/L to 24.9 jig/L; this maximum was measured at the bottom
depth at Location 2.0 in February. All copper concentrations, measured as total recoverable
copper, were less than 4 ptg/L, and over half (24 of 44) of the values were less than the ARL.
The maximum copper concentration recorded in 2007 (3.13 ptg/L) was measured in the
surface waters (0.3 m) at Location 11.0 in May. All values reported for cadmium, lead, zinc,
and copper in 2007 were below the State action level for each of these metals (NCDENR
2004).

No changes are planned for the water chemistry portion of the Lake Norman Maintenance -
Monitoring Program.
SUMMARY
Annual precipitation in the vicinity of MNS in 2007 totaled 78.2 cm and was the third lowest
measurement reported over the period 1975 — 2007, with lower values being recorded only in
1981 (64.4 cm) and 1986 (76.5 cm). Air temperatures near the McGuire Nuclear Station in
2007 were warmer than both 2006 and the long-term mean for the months of March, August,
September and October. The temporal differences were most pronounced in September and
October 2007 when temperatures averaged 2.8 and 4.1 'C warmer, respectively, than
recorded in 2006.
Temporal and spatial trends in water temperature and DO in 2007 were similar to those
observed historically, and all data were within the range of previously measured values.
Water temperatures in 2007 for the months of January, March, and April ranged from 0.1 to
3.8 OC warmer than measured in 2006 in both the mixing and background zones, whereas
2007 February temperatures were as much as 2.2 T cooler than observed in 2006. These
interammal differences in water temperatures paralleled differences exhibited in monthly air
temperature data but with about a one month lag. Reduced operations of Unit 1 at MNS in
2-13

Marchand April 2007 also undoubtedly contributed to these interannual differences during
the winter and early spring.
Summer (June, July, and August) water temperatures in 2007 were generally similar to those
observed in 2006 in both zones, with one notable exception. Surface water temperatures in
the miring zone in June 2007 were up to 2.7 °C cooler than observed in 2006, and appeared
to be related primarily to reduced operations of Unit l rather than to interannual differences
in air temperature. Late -summer, fall, and early winter water temperatures (September,
October, November, and December) in 2007 were consistently warmer in both zones than
those measured in 2006, and followed the trend exhibited inair temperatures, The most
striking differences were observed in the mixing zone in November when 2007 temperatures
were as much as 4.4 °C wanner than measured in 2006.
Temperatures at the discharge location in 2007 were generally similar to 200 (Figure -5)
and historical data. Temperatures in 2007 were slightly cooler; in the spring (March
temperatures were taken during a station outage), and warmer in the fall than observed in
2006. The warmest discharge temperature of 2007 at Location 4 (37. °C) occurred in
September and was identical to the maximum measured in 2006.
Seasonal and spatial patterns of DO in 2007 were reflective of the patterns exhibited for
temperature, i.e., generally similar in both the mixing and background zones. minter and
spring DO values in 2007 were generally equal to or slightly lower, in both the background
and mixing zones, than measured in 2006, except in February when 2007 DC values ranged
from 0.4 to 1.2 g/L higher than in 2006. The interannual differences in D4 values'
measured during this period appeared to be related predominantly to the differences in water
column temperatures in 2007 versus 2006. Summer DU values in 2007 were highly variable
throughout the water column in both the mixing and background zones ranging from highs of
6.0 to 8.0 g/L in surface waters to laws of 0.0 to 2.0 mg/L in bottom waters. This pattern is
similar to that measured in 2006 and earlier years. Unlike most previous years, summer DO
profiles in 2007 and 2006 were remarkably similar throughout the water column in both
zones, suggesting that those physical and metabolic processes that influence D4 within the
reservoir were proceeding at about the same rates in 2007 and 2006. All dissolved oxygen
values recorded in 2007 during this period were within the historical range.
Considerable differences were observed between 2007 and 2006 late summer and fall DO
values in bath the mixing and background zone, especially in the metal "on and
2-14

hypolimnion during the months of September, October, and November. The 2007 late
summer and autumn DO data indicated that fall convective reaeration proceeded slower and
was less complete throughout the water column than observed in the corresponding months
in 2006. Consequently, 2007 DO levels in either a portion or all of the water column were
less than observed ed in 2006, These between -year differences in DO corresponded strongly
with the degree of thermal stratification and interannual differences in air temperatures.
e seasonal pattern of Ua in 2007 at the discharge location was similar to that measured
historically, with the highest values observed during the winter and lowest observed in the
summer and early fall. Fall DO levels in 2007 at location 4.0 were slightly lower than
observed in 2006 due to warmer temperatures. The lowest DO concentration measured at the
discharge location in 2007 (5.5 mg/,) occurred in September, and was identical to that
measured in August, 2006; it was , also 1.4 /L higher than the historical minimum,
measured in August 200 (.1 g/L),
Reservoir -wide isotherm and isopleth information for 2007, coupled with heat content and
hypolimnetic oxygen data, illustrated. that Lake Norman exhibited thermal and oxygen
dynamics characteristic of historical conditions and similar to other Southeastern reservoirs
f comparable size, depth., flow conditions, and tophic status. Suitable pelagic habitat for
adult striped;bass, defined as that layer of water with temperatures :!� 26 OC and DO levels
2.0 g/L, was found lake -wide from mid September 2006 through early July 2007.
Beginning in late June 2007, habitat reduction proceeded rapidly throughout the reservoir
both as a result of deepening of the 26 IC isotherm and metalinmetic and hypolimnetic
deoxygenatin. Habitat reduction was most severe from id July through early September
when no suitable habitat was observed in the reservoir. Summer 2007 habitat conditions
were most recently similar to those measured in 2006 when habitat elimination was observed
for a period of about 50 to 60 days.. Observed striped bass mortalities in 207 totaled thirteen
fish.
All chemical parameters measured in 2007 were similar to 2006, and within the concentration
ranges previously reported for the lake during both preoperational and operational years o
S. Specific conductance values, and all concentrations of cation and anion species
measured, were low. Nutrient concentrations were also low with most values reported close
to or below the analytical reporting limit for that test. Concentrations of metals in 2007 were
low, and often below the analytical reporting limits. All values reported for cadmium, lead,
2-15

zinc, and copper in 2007 were below the State water quality standard or action level for each
of these metals.
Iron concentrations in surface and bottom waters were generally low (:� 0.40 mg/L) during,
2007 the only exceptions being a 0.2-g/L value measured in the bottom waters at
Location 2.0 in November, and a 1.26- g/L value measured at the bottom depth at Location
.0 in August. This latter value is the only instance in 2007 that an iron measurement
exceeded the North Carolina water quality action level for iron 1.0 mg/L). Similarly,
manganese concentrations were generally low (!� 100 g/L) in 2007, except during the
summer and :fall when bottom waters were anoxic. Manganese concentrations in the bottom
watersrose above the State water quality standard for this constituent (200 gg/L) at various
locations throughout the lake in summer and fall of 2007, and were characteristic of historical
conditions. This phenomenon, i.e., the release of manganese (and iron) from bottom
sediments in response to low redox "conditions (low oxygen levels), is co non in stratified
watertodies:

CHAPTER 3
PHYTOPLANKTON
INTRODUCTION
Phytoplankton standing crop parameters were monitored in 2007 in accordance with the
NPDES permit for McGuire Nuclear Station S). The objectives of the phytoplankton
study of the Lake Norman Maintenance Monitoring Program are to:
1. Describe quarterly patterns of phytoplankton standing crop and species composition
throughout Lake Norman; and
2. Compare phytoplankton data collected during this current study with data collected i
prior study years.
In previous studies on " Lake Norman considerable spatial and temporal variability i
hyto lankton standing crops and taxonomic composition have been reported (Duke Power
Company 1976, 1985; Menhinick and Jensen 1974; Rodriguez 1982). Rodriguez (1982)
classified the lake as oligo- esotrophic (low to intermediate productivity) based on
phytoplankton abundance, distribution, and taxonomic composition. Past maintenance
monitoring program studies have confirmed this classification (Duke Energy 2007).
METHODS AND MATERIALS
Quarterly sampling was conducted at Locations 2.0, 5.0 (mixing zone), 8.0, 9.5, 11.0, 13.0,
15.9, and 69.0 in Lake Norman (Figure -1). Duplicate grabs from 0. , 4.0, and 8.0 in (i.e.,
the estimated euhotic zone) were taken and then composited at all locations, except
Location 69.0, where grabs were taken at 0., 3.0, and 6.0 in due to the depth. Crab samples
were composited for each location. Sampling was conducted in February, May, August, and
November 2007. Secchi depths were recorded from all sampling locations. As in previous
years and based on the original design study (Duke Power Company 198), phytoplankton
density, biovolume, ;and taxonomic composition were determined for samples collected at
Locations 2.0, 5.0, 9., 11.0, and 15.9; chlorophyll a concentrations and sston dry and ash -
free dry weights were determined for samples from all locations. Chlorophyll a and total
3-1

phytoplankton densities and biovolumes were used in determining phytoplankton standing
crop. Field sampling and laboratory methods used for chlorophyll a, seston dry weights, and
population identification and enumeration were identical to those used by Rodriguez (1982).
Data collected in 2006 were compared with corresponding data from quarterly monitoring
beginning in August 1987,
RESULTS AND DISCUSSION
Standin Crop
I,---
Chlorophyll a
Chlorophyll a concentrations (mean of two replicate composites) ranged from a low of 1.96
gg/L at Location 8.0 in November, to a high of 13.66 gg/L at Location 69.0 in August (Table
3-1, Figure 3-1). All values were below the North Carolina water quality standard of 40 Itg/L
(NCDENR 1991). Lake -wide can chlorophyll concentrations were within ranges of those
reported in previous years, but were all below the long-term lake -wide means (Figure 3-2).
Seasonally, chlorophyll concentrations increased from February through May to the annual
maximum in August then declined to the annual lake -wide minimum in November. used, on
quarterly mean chlorophyll concentrations, the trophic level of Lake Norman was in the
oligotrophic (low) range during February and November and in the mesotrophic
(intermediate) range in May and August 2007. Over 59% of the mean chlorophyll a values
were less than 4 gg/L (oligotrophic), while all but one of the remaining chlorophyll a values
were between 4 and 12 gg/L (mesotrophic). The chlorophyll concentration from Location
69.0 in August was the only one greater than 12 pg/L (eutrophic, or high range). Historically,
quarterly mean concentrations of below 4 gg/L have been recorded on fourteen previous
occasions, while lake -wide mean concentrations of greater than 12 gg/L were only recorded
during May of 1997 and 2000 (Duke Power 1998, 200 1; Duke Energy 2007).
During 2007 chlorophyll a concentrations showed typical spatial variability. Maximum
concentrations among sampling locations were observed at Location 69.0 (furthest up -lake)
during all sampling periods, while minimum concentrations occurred at Location 9.5 in
February, Location 2.0 in May, Location 5.0 in August, and Location 8.0 in November (Table
3-1). The trend of increasing chlorophyll concentrations from down -lake to up -lake, which

had been observed during many previous years, was apparent to some extent during all
sampling periods (Table 3-1, Figure 3 -1).
Flow in the riverine zone of a reservoir is subject to wide fluctuations depending, ultimately,
on meteorological conditions (Thornton, et al. 1990), although influences may be moderated
due to upstream dams. During periods of high flow, algal production and standing crop
would be depressed due in great part to washout. Conversely; production and standing crop
would increase during periods of low flow resulting in higher retention time. However, over
long periodsof low flow, production and standing crop would gradually decline once more.
These conditions result in the comparatively high variability in chlorophyll concentrations
observed between Locations 15.9 and 69.0 throughout many previous years, as opposed to
Locations 2.0 and 5.0 which have usually shown similar concentrations during sampling
periods.
Mean quarterly chlorophyll concentrations during the period of record. (August 1987
November 2007) have varied considerably, resulting in moderate to wide historical ranges.
During February 2007, chlorophyll values at all but Location 690 were lower than in
previous February periods, while the value at Location 69.0 was higher than average (Figure
3-3). Long-term February peaks at Locations 2.0 through 9.5 occurred in 1996 while the
long-term February peak at Location 11.0 was observed in 1991. Long-term maxima at
Locations 1.0 and 15.9 occurred in 2003. The highest February value at location 69.0
occurred in 2001. , All locations had higher chlorophyll concentrations in February 2007 than
in February 2006 (Duke Energy' 2007).
During May, mean chlorophyll concentrations at Locations 2.0 and 5.0 were in the mid
historical range, while concentrations at Locations 8.0 through 15.9' were in the low range.
The concentration at Location 69.0 was once again in the high range (Figure 3-3). Long-term
May May peaks at Locations 2.0 and 9.5 occurred in 192; at Location 5.0 in 1991; at Locations
8.0, 11.0, and 13.0 in 1997; at Location 15.9 in 2000; and at Location 69.0 in 2001 May
2007 mean chlorophyll concentrations at all but Location 13.0 were higher than those of 2006
(Duke Energy 2007),
Although the lake -wide mean chlorophyll concentration in August 2007 was the highest of
the four sampling periods, mean chlorophyll concentrations at all but Location 6.0 were in
the low historical range, with Location 6.0 having a concentration in the high range (Figures
-2 and 3-. Long-term August peaks at Locations 2.0 and 5.0 were observed in 1998, while
3-3

August peaks at Locations 8.0 and 9.5 occurred in 1993. Long-term august peaks at
Locations 11.0 and 13.0 were observed in 1991 and 1993, respectively. The highest August
chlorophyll concentration from. Location 1.9 was observed in 1998, while Location ,69.0
experienced its long-term August peak in 2001. Mean chlorophyll concentrations for August
2007 were higher than those of August 2006 at all but Location 5.0 (Duke Energy 2007).
The lake -wide mean chlorophyll concentration in November 2007 was the lowest among all
four sampling periods (Figure -2). Chlorophyll concentrations at all but Location 69.0 were
in the low historical range and concentrations from Locations 5.0, 8.0, 9.5, and 1.9 were the
lowest November concentrations recorded from these locations (Figure -4). As was the case
during the previous sampling periods, the chlorophyll concentration at Location 69.0 was in
the high historical range. Long-term November peaks at Locations 5.0 and 8.0 occurred i
2006, while November maxima at Locations 11.4 and 15.9 occurred in 1996. The highest
November value at Location 13.0 was recorded. for 1992, while the November maxima at
Locations 2.0 and 9.5 were observed in 1997. The highest November chlorophyll
concentration at Location 69.0 occurred in 1991. November 2007 chlorophyll concentrations
at all but Location 69.0 were lower than during November 2006 (Duke Energy 2007):
Total Abundance
Density and biovolume are measurements of phytoplankton standing crops. In most cases
standing crop parameters mirror the temporal trends of chlorophyll concentrations. During
2007, mean seasonal standing crops increased from the annual minimum in February through
to the annual peak in August then declined through November. The lowest density (761
its/ L) and biovol e (551 mm3/ ) occurred at Location 9.5 in February (Table -2,
Figure - ). The maximum density (6,232 its/mL) and biovvol e (4,860 1 3) were
observed at Location 1.9 in August. Most standing crop values during February, May, and
August 2007 were higher than those of 2006, while values from November 2007 were lower
than in November of the previous year (Dube Energy 2007). Phytoplankton densities during
2007 never exceeded the NCB' guidelines for algae blooms of 10,000 units/mL density and
5,000 3/ 3 for biovolume (NCDE 1991). Densities or biovolumes in excess of N
guidelines were recorders in 1987, 1989, 1997, 1998, 2000, 2003, and 200 (Duke Power
Company 1988, 1990; Duke Power 1998, 1999, 2001, 2004a, Duke Energy 2007). During all
sampling periods phytoplankton densities and biovolumes demonstrated a spatial trend
similar to that of chlorophyll; that is, lower values at down -lake locations verses up -lake
locations (Table -2, Figure -1).
3-4

Seston
Seston dry weights represent a combination of algal matter and other organic and inorganic
material. Dry weights during 2007 were most often lower than those of 2006. As was
observed with chlorophylls and algal standing crops, a general pattern of increasing values
from down -lake to up -lake was observed during 2007 (Table 3-3 and Figure 3-1). From 1995
through 1.997 seston dry weights had been increasing (Duke Power 1998). Values from 1998
through 2001 represented a reversal of this trend, and were in the low range at most locations
during 1999 through 2001 (Duke Power 2002). Low dry weights during these years were
likelya result of prolonged drought conditions resulting in low sedimentation from runoff
(Figure 2-2a). From 2002 through 2006, dry weights gradually increased throughout the lake,
followed by a dramatic decline in 2007. The lake -wide average dry weight in 2007 was the
lowest since dry weights were recorded in 1988. These exceptionally low values were likely
due to severe drought conditions throughout the watershed during 2007.
Seston ash -free dry weights represent organic material and may reflect trends of chlorophyll
a. This relationship held true for the most part during 2007, especially with respect to
increasing values from down -lake to up -lake areas, as was the case with chlorophyll
concentrations and standing crop values (Tables 3-1 through 3-3).
Secchi DWths
Secchi depth is a measure of light penetration. Secchi depths were often the inverse of
suspended sediment (seston dry weight), with the shallowest depths at Locations 13.0
through 69.0 and deepest from Locations 9.5 through 2.0 down -lake. Depths ranged from
1.10 m at Location 13.0 in February and 69.0 in August, to 3.7 rn at Location 8.0 in May
(Table 3-1). The lake -wide mean Secchi depth during 2007 was slightly higher than in, 2006
and was within historical ranges for the years since measurements were first reported in 1992.
The deepest lake -wide mean Secchi depth was recorded for 1999 (2.26 m) (Duke Power
2000).
Community Compqsjtion
One indication of "balanced indigenous populations" in a reservoir is the diversity, or number
of taxa, observed over time. Lake Norman typically supports a rich community of
3-5

phyroplankton species. This was certainly true in 2007. Ten classes comprising 98 genera
and 257 species, varieties, and forms of phytoplankton were identified in samples collected
during 2007, as compared to 91 genera and 23 lower taxa identified in 200 (Table -4).
The 2007 total represented the highest number of taxa recorded in any year since monitoring
began in 1987 (Duke Energy 007). Fifteen taxa previously"unrecorded during the
Maintenance Monitoring program were identified during 2007.
Deci s Conmosition and Seasonal Succession
The phytoplankton community in Lake Norman varies both seasonally and spatially.
Additionally, considerable variation may occur between ;years for the same months sampled.
During February 2007, cryptophytes (C tophyceae) dominated densities at all locations
(Table 3-5 - Figures 3-5 through 3-. During most previous years, cryptophytes and
occasionally diatoms dominated February phytoplankton samples in .Lake Norman. The most
abundant cryptophyte during February 2007 was the small flagellate Rhodomonas minuta. R.
minuta has been one of the most common and abundant forms observed in Labe Norman
samples since monitoring began in 1987. Cryptophytes are characterized as light limited, and
are often found deeper in the water column or near surface under low light conditions, which
are common during winter (Lee 1989).
In May, diatoms (acillariophycea) were dominant at all locations (Table -5, Figures 3-5
through 3-9). The most abundant diatom at all locations was the pennate, F'ragillaria
croto ensis. Diatoms have typically been the predominant forms in May samples of previous
years; however, cryptophytes dominated May samples in 1988, and were co -dominants with
diatoms in May 1990, 1992, 1993, and 1994 (Duke Power Company 1989, 1990, 1991, 1992,
1993,1994, 1995, 1996, 1997 Duke Power 1998, 1999, 2000, 2001, 2002, 2003, 2004a,
2005; Duke Energy 2006 007).
During August 2007, green algae (Chlorophyceae) dominated densities at all locations
(Figures -5 through 3-9). The most abundant green alga was the small desmid, Cosmarium
asphearosporum var. strigos m (Table 3-7). During August periods of the Lake Norman
study prior to 1999, green algae, with blue-green algae yxophyceae) as occasional
dominants or co -dominants; were the primary constituents of summer phytoplankton
assemblages, and the predominant green alga was also C: asphearosporum var. strigosum
(Duke Power Company 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997; Duke Power
3-6

1998, 1999). During August periods of 1999 through 2001, Lake Norman phytoplankton
assemblages were dominated by diatoms, primarily the small pennate, Anomoeoneis vitrea
(Duke Power 2000, 2001, 2002). A. vitr°ea has been described as typically periphytic and
widely distributed in freshwater habitats and was identified as a major contributor to
periphyton communities on natural substrates during studies conducted from 1974 through
1977 (Derwort 1982). The possible causes of this significant shift in summer taxonomic
composition were discussed in earlier reports and included deeper light penetration (the three
deepest lake -wide secchi depths were recorded from 1999 through 2001), extended periods of
low water due to drawdown, and shifts in nutrient inputs and concentrations (Duke Power
2000, 2001, 2002). Whatever the cause; the phenomenon was lake -wide and not localized
near MNS- or Marshall Steam. Station (MSS), therefore, it was most likely due to a
combination of environmental factors, and not station operations. 'Since 2002, taxonomic
composition during the summer has shifted back to green algae predominance (Duke Power
2003, 2004a, 2005 Duke Energy 2006, 2007).
During November 2007, densities at all locations were: again dominated by diatoms. The
most abundant species at Locations 2.0, 11.0, and. 15.9 was the pennate diatom, 7'abellaria
enestrata (Table -5, Figures 3-5 through -9). At Locations 5.0 and. 9.5, the most abundant
diatom was the centrate, Melosir°a arnbigua. These diatoms have been among the most
common and abundant forms found in Lake Norman throughout the Labe Norman
Maintenance Monitoring program.
Blue-green algae, which are often implicated in nuisance blooms, were never abundant in
007 samples (Duke Energy 2007). Their overall contribution to phytoplankton densities
was slightly higher than in 2006, but densities seldom exceeded 3% of totals, Prier to 1991,
blue-green algae were often dominant atup-lake locations during the summer(Duke Power
Company 18, 189, 10, 11, 1992).
FUTURE STUDIES
No changes are planned for the phytoplankton portion of the Lake Norman an Maintenance -
Monitoring Program.
3-7

Lake Norman continues to be classified as oligo-mesotrophic based on long-term, annual
mean chlorophyll concentrations. Chlorophyll concentrations during 2007 were most often
within historical ranges, however, several record low chlorophyll concentrations were
recorded in November. Lake -wide mean chlorophyll increased from February through
August then declined to the annual minimum in November. Some spatial variability was
observed in 2007, however, maximum chlorophyll concentrations were typically observed
up -lake at Location 69.0, while minimum chlorophyll concentrations were recorded from
down -lake at Locations 2.0 through 9.5. The highest chlorophyll value recorded in 2007,
13.66 gg/L, was well below the NC State Water Quality standard of 40 jig/L.
Phytoplankton densities and biovolumes during 2007 were generally higher than in 2006.
Phytoplankton densities during 2007 never exceeded the NC guidelines for algae blooms.
Standing crop values in excess of bloom guidelines have been recorded during seven
previous years of the program. As in past years, higher standing crops were usually observed
at up -lake locations, while comparatively lower values were noted down -lake.
Seston dry and ash -free weights were most often lower in 2007 than in 2006 and down -lake
to up -lake differences were apparent during all quarters. Maximum dry and ash -free weights
were generally observed at Location 69.0. Minimum values were noted at Locations 2.0
through 9.5.
Secchi depths reflected suspended solids with shallow depths related to high dry weights.
The lake -wide mean Secchi depth in 2007 was slightly higher than in 2006 and was within
historical ranges recorded since 1992.
Diversity or the number of tax a of phytoplankton in 2007 was the highest yet recorded. The
taxonomic composition of phytoplankton communities during 2007 was similar to those of
many previous years. Cryptophytes were dominant in February, while diatoms were
dominant during May and November, Green algae dominated phytoplankton assemblages
during August. Blue-green algae were slightly more abundant during 2007 than during 2006,
but their contribution to total densities seldom exceeded 3%.
3-8

The most abundant alga, on an annual basis, was the cryptophyte R. manuta. The most
abundant diatom in May was F. crotonensis, while the most abundant diatoms during
November were T. fenestrata and M ambzgua. The small desmid, C. asphearosporum var.
strigosum was dominant in August 2007. All of these to a have been common ion d abundant
throughout the Lake Norman Maintenance Monitoring program.
Lake Norman continues to support highly variable and diverse phytoplankton communities.
o obvious short-term or long-term impacts of station operations were observed.

CHAPTER
ZOOPLANKTON
INTRODUCTION
The objectives of the Lake Norman Maintenance Monitoring Program for zooplankton are to:
1. Describe and characterize quarterly patterns of zooplankton standing crops at selected
locations on Lake Norman d
. compare and evaluate, where possible, zooplankton data collected during 2007 with
historical data collected during the period 1987 — 2006.
Previous studies of Lake Norman zooplankton populations, using monthly data, demonstrated
a bimodal seasonal distribution with highest values generally occurring in the spring, and a
less pronounced fall peak. Considerable spatial and year-to-year variability has been.
observed in zooplankton abundance in Lake Norman (Duke Power Company 1976, 1985;
Hamme 1982; Menhinick and Jensen 1974). Since quarterly sampling was initiated in
August 1987, distinct bimodal seasonal distribution has been less apparent; due to the lack o
transitional data between quarters.
METHODS AND MATERIALS
Duplicate 10 m to surface, and bottom to surface net tows were taken at Locations 2.0, 5.0,
9.5, 11.0, and 15.9 in Lake Norman (Figure -1,) during each season: winter (February),
spring (May), summer (August), and fall (November) 2007. For discussion purposes the 10
m to surface tow samples are called "epili etic" samples and the bottom to surface net tow
samples are called "whole -column" samples. Locations 2.0 and 5.0 are defined as the
"mixing zone" and Locations 9.5, 11.0 and 15.9 are defined as "background" locations. Field
and laboratory methods for zooplankton standing crap analysis were the same as those
reported in Harnme (19). Zooplankton standing crop data from 2007 were compared with
corresponding data from quarterly monitoring begun in :August 1987.

RESULTS D DISCUSSION
Highest epilinmetic zooplankton densities at Labe Norman locations have predominantly
been observed in the spring, with winter peaks observed. about 25% of the time,`and peaks
observed only occasionally in the summer and fall (Duke Energy 2007). During 2007,
annual epilimnetic maxima were recorded from Locations 2.0, 5.0, and 15.9 in the spring.
while Locations 9.5 and. 11.0 demonstrated peak annual densities in February (Table 4-1,
Figures -1 and 4-2). The lowest epilimnetic densities occurred in the fall at all but Location
15.9, which had the annual minimum density in the summer. Epilinmetic zooplankton
densities ranged from a low of3 ,564/ 3 at Location 2.0 in the fall, to a high of 94,1 2/ 3
at Location 15.9 in the spring.
Maximum densities in 2007 whole -column samples were observed during different seasons
at different locations. At Locations 9.5 and 11.0, maximum values occurred in the winter,
annual maxima at Locations 2.0 and 15.9 were observed in the spring, and the highest density
from Location 5.0 occurred in the summer (Table 4-1 and Figure 4- 1). Minimum whole -
column densities were observed in the summer at Locations 11.0 and 15.9 and in the fall at
Locations 2.0, 5.0, and 9.5. Whole -column densities ranged: from a low' of 30,61 I/M3 at
Location 2.0 in the fall, to 21 ,242/ 3 at Location 15.9 in the spring.
Consistent with historical data, during 2007 total zooplankton densities were most often
higher in epilinmetic samples than in whole -column samples (Duke Energy 2007). This is
related to the ability of zooplankton to orient vertically in the water column in response to
physical and chemical gradients and the distribution of food sources, primarily
phytoplankton, which are generally most abundant in the euphoric zone (Hutchinson 1967).
Since epilimnetic zooplankton communities are far more representative of overall seasonal
and temporal trends, most of the following discussion will focus primarily on zooplankton
communities in this area of the water column.
Although spatial distribution varied among locations from season to season, a general pattern
of lower average densities ftom the mixing zone, as compared to background locations, was
observed during 2007 (Table 4-1, Figures 4-1 and 4- ). Location 15.9, the uppermost
background location, had higher epilimnetic densities than mixing zone locations during all
sampling periods (Table 4-1). This spatial trend was similar to that of the phytopl on
4.2

(Chapter 3. In most previous years of the program, background locations had higher mean
densities than mixing zone locations (Figures 4-3 through 4-6; and Duke Energy 2007).
Historically, both seasonal and spatial variability of epilinmetic zooplankton densities have
been much higher among background locations than among'mixing zone locations. The
uppermost Location 1 . , showed the greatest range of densities during 2007 (Table' 4-1,
Figures 4-3 through 4-6). Apparently, epilimnetic zooplankton communities are more greatly
influenced by environmental conditions at theup-lake locations than at the down -lake
locations. Location 15.9 represents the transition zone between river and reservoir where
populations would be expected to fluctuate due to the dynamic nature of this region of Lake
Norman. At the locations nearest the dam (Locations 2.0 and 5.0), seasonal variations are
dampened and the overall production would be louver due to the relative stability of this area
(Thornton, et al. 1990). Additionally, the effects of MNS once -through cording could cause
somewhat lower production at these locations. A similar trend was observed in the
pbytoplankton communities (Chapter 3).
Epilimnetic zooplankton densities during 2007 were most often within historical ranges
(Figures 4-3 through 4-6). The exceptions were at Location 9.5 in the summer and Location
15.9 in the winter. On both occasions, these locations demonstrated long-term seasonal
maximum densities (Figures 4-3 and 4-6).
The highest winter densities recorded from Locations 2.0 and 11.0 occurred in 1996, while
the winter maximum at Location 9.5 was recorded. in 19 (Figure 4-3). The winter maxima
from Locations 5.0 and 15.9 occurred in 2004 and 2007, respectively. Long-term maximum
densities for spring were observed at Locations 2.0 and 5.0 in 2005, while the highest spring
values from Locations 11.0 and 1.9 occurred in 2002. The highest spring peak. at Location
9.5 was observed in 2005 (Figure -4). Long-term summer maxima occurred in 1988 at
Locations 2.0, 5.0, and 11.0, while summer maxima at Locations 9.5 and 15.9 occurred in
2007 and 2003, respectively (Figure 4-5). Long-term maxima for the fail occurred at all but
Location 15.9 in 2006, while the long-term maximum at Location 15.9 was recorded in 1999
(Figure 4-).
From 1990 -- 2003, the densities at mixing zone locations in the spring, summer, and fall
demonstrated moderate degrees of year-to-year variability, and the long-term trend at mixing
zone locations in the spring had been a gradual increase through 2005. During the spring of
2006, zooplankton densities in the mixing zone declined sharply, as compared to 2005 and
4-3

were well within earlier historical ranges. During 2007, mixing zone locations demonstrated
increases. Year-to-year fluctuations of densities in the mixing zone during the winter have
occasionally been quite striking, particularly between 1991 and 1997. The background
locations continue to exhibit considerable year-to-year variability in all seasons (Figures -3
through 4-6).
communitV Com osition
One hundred and twenty-three zooplankton taxa have been identified since the Lake Norman
Maintenance Monitoring Program began in ,August 1987 (Table 4-2). Forty-nine taxa were
identified during 2007, as compared to 44 recorded for 2006 (Duke Energy 2007). Two
previously unreported taxa, the copepod Eucyclops prionc phorus and the rotifer, Keratella
timer Cana, were identified in 2007.
In 2006, copepods were the most abundant zooplankters in eight samples; one in the winter
and seven in the summer (Duke Energy 2007). During 2007, copepods were dominant in
only three samples. the epilimnion at Locations 2.0 and 5.0 in the spring, and the whole
column sample from Location 2.0 in the summer (Table 4-1). Cladocerans, most often the
leash abundant forms in Lake Norman, were dominant in two whop column samples, one
from Location 2.0 in the spring and another from Location 9.5 in the winter (Table -1).
Rotifers were dominant in all other samples collected in 2007. During most years,'
icros stace s (copepods and cladocerans) dominated mixing zone samples, but were less
important among background locations (Figures 4-7 and 4-8). Compared to 2006,
microcrustaceans showed a slight increase in relative abundances in the epilimmon of the
mixing None, while they demonstrated a slight decrease among whole -column samples at
these locations (Figure 4- ). At background locations microcrustacean relative abundances
were similar to those of 2006 (Figure 4- )
Cop pod
As has always been the case, copepod populations were consistently dominated by immature
forms (primarily nauphi) during 2007. Adult copepods seldom comprised more than 7% o
the total zooplankton density at any location. Tropoc c ops was the most important genus in
adult populations, particularly during summer and fall (Table 4-3). Epishura was important
among winter and spring samples, while Cyclops and Diaptom s were occasionally abundant.
-

Similar patterns of copepod taxonomic distributions were observed in previous years (puke
Energy 2007).
Copepods tended to be somewhat more abundant at background locations than at mixing
zone locations during 2007, and their densities peaked at all locations in the spring, as was
typically recorded during past years (Table 4- 1; Figure 4-),
Rotif r a
olyart ra was the most abundant rotifer at all locations during the fallof 2007, when it
demonstrated dominance among all rotifer populations (Table -3). Keratella was the :most
abundant rotifer in most spring samples, while Ptygura was most oven dominant among
summer populations. During the winter, Asplanchna was the most abundant rotifer in
epilimnetic samples from Locations 2.0, 5.0, and: 9.5 and among whole column samples at
Locations 2.0 and 9.5. Conoc ails and ,Sync a to were occasionally dominant in samples
from 'nter, spring, and summer. All of these taxa.' have been identified as important
constituents of rotifer populations, as well as zooplankton communities, in previous studies
(Duke Energy 2007, Harmne 12).
Long-terrn trackingof rotifer populations indicated high year-to-year seasonal variability.
Peak' densities have most often occurred in the winter and spring, with occasional peaks in
the summer and fall (Figure 4-11). During 2007, peak rotifer densities were observed at
ring zone locations in the summer and at background locations in the spring.
FUTURE STUDIES
No changes are planned for the zooplankton portion of the Lake Norman Maintenance -
Monitoring Program.
SUMMARY -
Maximum zooplankton densities most often occurred in the spring of 2007, while minimum
ooplankton densities were generally noted in the fall. As in past years, epilinmetic densities
were higher than whole -column densities. Mean zooplankton densities tended to be higher
4-5

among background locations than among mixing zone locations during 2007. Spatial trends
of zooplankton populations were similar to those of the phytoplankton, with increasing`
densities from down -lake to up -lake. From around 1997 through 2005, a year-to-year trend
of increasing zooplankton densities was observed among mixing zone locations in the spring.
Densities at these locations declined sharply in 2006, followed by an increase in 2007. Long-
term trends showed much higher year-to-year variability at background locations than at
mixing zone locations.
Epilinmetic zooplankton densities were generally within ranges of those observed in previous
years. The exceptions were record high densities during winter at Location 15.9 and during
the summer at Location 9.5.
One hundred andtwenty-three zooplankton taxa have been recorded from Lake Norman sine
the Program began in 1987 (9 were identified during 2007). Two previously unreported
taa were identified during 2007.
Overall, relative abundance of copepods in 2007 decreased over 2006, and they were
dominant in only three samples. Cladocerans were dominant in two samples, while rotifers
were dominant in all remaining samples. The relative abundance of microcrustaceans
increased slightly in the epilimnion of the mixing zone since 2006, but decreased among
whole -column samples since the previous year. At background locations, relative
abundances of microcrustaceans in 2007 were similar to those of 2006. Historically,
copepods and rotifers have most often shown annual peaks in the spring, while cladoerans
continued to demonstrate year-to-year variability.
Copepods were dominated by immature forms with adults rarely accounting for more than
7% of zoopla on densities. The most important adult copepod was Tropocyclops, as was
the case in previous years. Bosmina was the predominant cladoceran, as has also been the
case in most previous years of the program. Bosminopsis dominated several cladoceran
populations during the summer. The most abundant rotifers observed in 2007, as in many
previous years, were P l arthra, Keratella, and Ptygura, Conochilus, Asplanchna, and
Syncheata were also important among rotifer populations.

Lake Norman continues to support a highly diverse and viable zooplankton community.
Other than somewhat lower productivity from induced mixing at Locations 2.0 and 5.0,
o impacts of plant operations were observed.

CHAPTER 5
FISHERIES
INTRODUCTION
In accordance with the NPDES permit for McGuire Nuclear Station ( S) and associated
requirements ftom the North Carolina . Wildlife Resources Commission (NCWRC),
monitoring of specific fish population parameters in Lake Norman continued during 2007.
The components of this program were:
1. spring electrofishing survey of littoral fish populations with emphasis on age, growth,
size distribution, and condition of spatted bass and largemouth bass;
fall electrofishing survey to assess largemouth and spotted bass young -of -year
abundance;
3. summer striped bass mortality surveys;
4. winter striped bass gill net survey with the NCWRC with emphasis on age, growth,
and condition;
. fall hydroacoustic and purse seine surveys of pelagic fish abundance and species
composition;
. fall crappie trap -net survey with the NCWRC with emphasis on age and growth.
METHODS AND MATERIALS
Spring Electrofishing Survey
A spring electrofishing survey was conducted in March and April at three locations: (1) near
Marshall Steam Station (MSS) in Zone 4, (2) a reference (REF) area located between
een
McGuire Nuclear Station S) and MSS in Zone 3, and (3) near MNS in Zone I (Figure -
1). The locations sampled in 2007 were identical to historical locations sampled since 1993
and consisted of ten 300-m shoreline transacts at each location. Tra sects included habitats
representative of those found in Lake Norman. Shallow fiats where the boat could not access
within 3-4 rn of the shoreline were excluded. All sampling was conducted during daylight,
when water temperatures were expected to be between 15 and 20 °C. All stunned fish were
5-1

collected and identified to species (scientific names of fish collected are listed in Table -1).
Fish were enumerated and weighed in aggregate by taxon, except for largemouth and spotted
ass, where total lengths ( n) and weights () were obtained for each individual collected.
Sagittal otoliths were removed from all bass > 125 mm, long (bass < 125 nun were assumed
to be age 1 because young -of -year bass are historically not collected in spring samples) and
sectioned for age determination (Devries and Frie 1996). Growth was calculated with the
mean length for all fish of the same age. Condition based on relative weight was calculated
for largemouth bass >150 turn long and spotted bass >100 mm long, using the formula Wr
(W x 100, where W — weight of the individual fish (g) and Ws = length -specific mean
weight (g) for a fish as predicted by a length -weight equation for that species (Anderson and
Neumann 1996),
Fall Electrofishine Survevsfor Youne-of-Year Bass
A fall electrofishing survey was conducted in November at the same three locations as the
spring survey and consisted of five 300-m shoreline transects at each location. Again,
shallow flats where the boat could not access within 3-4 m. of the shoreline were excluded.
All stunned bass were collected, identified to species, and individually measured and
weighed. A year class "cut off" of 150 mm was determined for all black bass by examining
length -frequency data.
Summer Strined Bass Mortalitv Survevs
Mortality surveys were conducted weekly during July and August to specifically search for
dead or dying striped bass in Zones 1-. All observed dead striped bass were collected
during these surveys and their location was noted. Individual total lengths were measured
prior to disposal.
Striped Bass Netting u g
Striped bass were collected for age, growth, and condition (Wr) determinations in early
December by Duke Energy (DE) personnel. Four monofila ent nets (76.2 m, long x 6.1 m
deep), two each containing two 3 8. 1 -m panels of 3 8- and 5 1 -imn square mesh and two each
containing 3'8.1-m panels of 6- and 76-mm square mesh, were set overnight in areas where
striped bass were previously located. Individual total lengths and weights were obtained for
5-

all striped bass collected. Sagittal otoliths were removed to determine age, growth, and
condition ( r), as described previously for largemouth bass. Additionally, all catfish
collected were identified and enumerated by species.
Fall Hydroacoustics and Purse Seine Surveys
The abundance and distribution of pelagic prey fish in Lake Norman were determined using
mobile hydr acoustic (Brandt 1996) ' d purse seine (Hayes et al. 1996) techniques. The lake
was divided into six zones (Figure 5-1) due to its large size and spatial heterogeneity.
mobile hydroacoustic survey of the entire lake was conducted in mid -September with
multiplexing, side- and down -looking transducers to detect surface -oriented fish and deeper
fish (Prom 2.0-m depth to the bottom), respectively. Both transducers were capable of
determining target strength directly by measuring fish position relative to the acoustic axis.
Purse seine samples were also collected in mid -September from the do lake (Zone 1),
idlake Gone 2), and u lake (Zone 5) areas of the reservoir. The purse seine measured 118
9 m with a mesh size of 4.8 mm. A subsample of forage fish collected from each area was
used to estimate taxa composition and size distribution.
Crappie Trap -Net Survey
Duke Energy personnel provided logistical; support to the NCWRC during Lake Norman
crappie population sampling in early November as described by Nelson and Dorsey (2005).
Crappie were collected with trap nets, identified to species, measured for individual total
length and weight, and saittal otoliths were removed for age and growth determinations.
RESULTS DISCUSSION
Sprig Electrofishing Surveys
Electr fis i g was conducted at water temperatures ranging from 14.6 to 20.0 'C. One
thousand three hundred forty fish (19 species and two hybrid complexes) weighing 125.3 k
were collected in the MSS area, 1,673 fish (0 species and two hybrid complexes) weighing
77.8 kg in the REF area, and 1563 fish (12 species andone hybrid complex) weighing 50.6
5-

kg in the MNS area (Table 5-). Overall,; bluegill dominated samples numerically, white
common carp, largemouth bass, and spotted bass dominated samples gravi etricaly.
Total numbers of fish collected in spring 2007 were highest in the REF area, intermediate in
the MNS area, and lowest in the MSS area (Figure -2). There is no apparent trend in the
number of fish collected within or among areas since 1993.
Total biomass of fish was highest in the MSS area, intermediate in the REF area, and lowest
in the MNS area, following the trend of previous years. This ;spring trend in Lake Norman
fish biomass supports the spatial heterogeneity theory noted by Suer et al. (156). The
authors reported that fish biomass was higher uptake than do lake; due to higher levels of
nutrients and resulting higher productivity uptake versus downlake. The spatial heterogeneity
theory; is further supported by higherconcentrationsof chlorophyll a, greater phytoplankton
standing craps, and elevated epilinmetic zooplankton densities in uptake compared to
do lake regions of Lake Norman (Chapters 3 and 4).
Spotted bass, thought to have originated from angler introductions, were first collected in
Lake Norman in the MNS area during a 2000 fish health assessment survey. They have
increased in numbers and biomass since 2001 spring electrofishing samples (Figure 5-3) and,
in 2007, were most abundant in the MSSarea, intermediate in the REF area; and least
abundant in the MNS area. Biomass was highest in the MNS area, intermediate in the REF'
area, and lowest in the MSS area.
n 2007, small spotted bass (< 150 ) dominated the black bass catch in all areas sampled:
(Figure 5-4), and their growth was generally similar among all areas sampled (Table -3).
Spotted bass Wr ranged from 6.4 for fish 0-149 runi long in the NWS area to 55.5 for fish
0-399 min long in the MSS area (Figure 5-5). Overall, spotted bass Wr values were
highest in the MSS area (75.3), intermediate in the REF,area (7.1), and lowest in the MNS
area (71.6); a decrease relative to 2006 values SS=77.2, REF 80.7, S=77.4) and'
within the range of observed historical values (71.-52.3) (Duke Power unpublished data,
2004, 2005; Duke Energy 2006, 2007).
Relative to 2006, 2007 largemouth bass numbers increased slightly in the REF and MNS
areas and decreased slightly in the MSS area (Figure5-6). Largemouth bass biomass
increased in the MSS and REF areas and decreased in the MNS area. Numbers and biomass
ass
values at all locations were generally similar to 2006, the lowest recorded since sampling
5-

began in 1993. As in most years, 2007 largemouth bass numbers and biomass were highest
in the MSS area, intermediate in the REF area, and lowest in the NMS area.
Since 2000, largemouth bass >300 mm dominated -the catch in all three sampling areas (Duke
Power 2001, 2002, 2003 2004, 2005 Energy 2006), with largemouth bass < 150 mm,
low in abundance. An exception was in 2006, where a high abundance of largemouth bass <
150 mm occurred in the MSS area (Duke Energy 007). In 2007, largemouth bass >00 were
relatively abundant, but not dominant (Figure 5-4)
There was no trend in largemouth bass growth among areas in 200 (Table -3) however,
largemouth bass mean lengths for ages 2, 3 and 4 were generally higher beginning in 2003,
relative to historical data (197 — 78, 1993, and 1994)( able 5-4). While displacement of
largemouth bass since the introduction of spatted bass in the louver lake is apparent, the direct
effect on largemouth bass recruitment is indeterminate, possibly due to confounding effects
of other introductions including alewife and white perch (Kohler and Ney 1980, Madenian et
al. 2000).
Largemouth bass Wr ranged from 791 for Fish 200-249 mm long to 89.9 for fish 00-349
m long, both in the REF area (Figure 5- ). Overall, largemouth bass Wr values were
highest in the MNS area (84.8) intermediate in the MSS area (84.6), and lowest in the REF
area (82.5); a decrease relative to 2006 values ( = 6. , MSS=87.2, F=88.0) and
`thin the range of observed historical values (76.0-89.9). (Duke Power unpublished data,
2004, 2005; Luke Energy 2006, 2007).

Summer Strined Bass Mortalitv Survevs
In 2007, a total of 13 dead striped bass were collected during the July -August surveys (Table
5-5). Since the survey began in 1983, summer mortalities in excess of 25 dead striped bass
occurred in three years: 163 in 1983, 43 in 1986, and 2,610 in 2004.
Striped Bass Netting Survey
Dominated by age I and age 2 fish, 181 striped bass were collected in early December 2007
(Figure 5-8). Striped bass growth was fastest through age 3 and slowed with increasing age.
Additionally, mean Wr was highest for age I fish and declined with age. Mean Wr was 79.5
for all striped bass in 2007, within the range of observed historical values (78.5-84. 1).
Growth and condition in 2007 were similar to historical values since consistent gillnetting
began in 2003 (Duke Power 2004, 2005; Duke Energy 2006, 2007).
The December striped bass gillnetting also yielded 76 catfish. Blue catfish (63) dominated
the catch, followed by flathead catfish (11), and channel catfish (2).
Fall Hvdroacoustics and Purse Seine
Average forage fish densities in the six zones of Lake Norman ranged from 1,338 (Zone 1) to
13,421 (Zones 5 and 6) fish/ha in September 2007 (Table 5-6). Zone 6 fish densities were
assumed to be the same as Zone 5, as the shallow nature of the riverine Zone 6 limits habitat
available for acoustic sampling. The lake -wide population estimate in September 2007,
approximately 72 million fish, was within the range of annual estimates since 1997 and well
above the lowest estimate of 47.1 million recorded in 2004 (Figure 5-9). As in most years
since 1997, Zone 5 had the highest forage fish density estimates. No temporal trends are

The overall increase and subsequent decrease in the percent composition of alewife was
concurrent with an increase in the threadfin shad modal length class and subsequent decrease
to values measured prior to the alewife introduction.
Crappie Trap -Net Study
In 2007, NCWRC personnel set 90 overnight trap -nets in Lake Norman. They collected`350
black crappie and 24 white crappie. Various life history data were collected for use in fish
management decisions.
FUTURESTUDIES
In addition to the 2007 Lake Norman Monitoring Program surveys, DE will conduct biennial
fall trap -net surveys with the NCWRC for crappies, with emphasis on age and growth.
Additionally, DE will conduct purse seine sampling in late June/early July 2008 to assist
NCWRC in evaluating the changing forage fish conununity. These changes were approved
by NCWRC in a letter dated March 7, 2008.
SUMMARY
In accordance with the Lake Norman Maintenance Monitoring Program for the MNS NPDES
permit, specific fish monitoring programs continued during 2007. Spring ele trofishing
indicated that 12 to 20 species of fish and two hybrid complexes comprised fish populations
in the three sampling areas, and numbers and biomass of fish in 2007 were generally similar
to those noted annually since 1993. Largemouth bass, numbers and biomass continue to
decline in recent years and the 2007 numbers and biomass were some of the lowest recorded
=since sampling began in 1993. During 2007, the number of summer striped bass mortalities
(13) and winter mean relative weight (79.5) were similar to those of previous years.
Hydroacoustic sampling estimated a forage fish population of approximately 72 million in
2007, co parable to previous years. After an increase in 2006, purse seine sampling
indicated a decrease in the percentage of alewives in 207 to the lowest percent composition
since their 1999 introduction. During 2007, threafin shad lengths remained at pre -alewife
introduction sizes:

Mr. Mile Parlor
This letter is the required 5 day follow-up report to the 24 hour notification made to NC DENT -
IVlooresville involving a release that occurred at the McGuire Nuclear Station on February 7,
2(,
Description of Non-compliance
Release of wastewater through an unapproved discharge point.
n 2/7/2008, as part of our on -going investigation into the release reported on 2/4/08 at our Final
Holdup Pond, we identified as new release that appears as if it may have existed :since plant start-
up. This newly identified discharge is to a wooded area below the final holdup pond. The
release is arming from our pH monitoring and adjustment system and loss of flow indication
line. The pH monitoring and adjust anent system checks the pH of the discharge flow from our
chemical treatment ponds. 1f the pH is out: of specification, it sends as signal to stop the discharge
flour. Set points for ply are 6.2 and 8.8 so that we will not exceed our permit limits for pH of 6 -
. Once the effluent has passed through the pH probe it is routed to as pipe which discharges to a
valve; pit, The valve pit has as pipe in it that discharges to the wooded area about 300 feat from
the final holdup pond. This release only occurs during; an effluent discharge to wastewater
Outfall 002. The effluent that goes to the pipe in the woods has already gene through treatment
and is within release specifications for Outtall 002.
The release rate is approximately 1.3 gallons per minute, 1872 gallons per day during wastewater
releases, Chemistry personnel were not aware that the pit was being released to the environment.

FFPV
The release has been stopped and will be re-routed to be in compliance with our NPDES permit
requirements.
This release also contains a small amount of tritium, a radioactive isotope. Sampling indicates
the release is below the drinking water limits for reporting. This release has already been
reported to the NRC (Nuclear Regulatory Commission) under our groundwater monitoring
program.
On /8/008,
At around 4:20 pm on /08/2008, the release from the sample lines was reported to NCDENR in
Mooresville to Ms. Dee Browder. At that time it was determined that no 5 day follow-up report
would be required., however Ms. Browder did request that we follow-up with Mr. Mike Parker on
Monday, 2/11 /2008 to see if there were any questions with the report.
n /11/08, we contacted Mr. Mike Parker to discuss the release report we made on 2/8/2008
At that time we discussed the potential for this release to have reached surface water during a
rain event. The release could potentially reach a wetland area below the discharge point of the
pipe: in the wooded area. Mr. Parker suggested that we file a fallow -up report to document the
release.
During the investigation of the release it was observed that there is a small amount of ground
water leaking into the valve pit around the discharge pipe going to Outfall 002. It is estimated
that this leakage is less than I gallon per minute. Samples taken of this leak indicate that it is not
wastewater based on the amount of tritium contained in it.
temporary modification has been implemented to route the discharge from the laid probes and
loss of flow instrumentation back to the plant's chemical treatment ponds so that the discharge is
routed to our permitted discharge point, Outfall 002. A permanent resolution for this discharge i
being developed by our Engineering and Chemistry groups that will be fully compliant with our
NPI ES permit.
If you have questions about the data reported, please contact John C. Williamson: by email at
[e-mail] or phone [phone].

Mooresville involving a release that occurred at the McGuire Nuclear Station on February 3,
2008.
Description of Non-compliance
Release of waste water to the ground from our Final Holdup fond (concrete lined waste water
treatment pond).
Between 01/28/08 and 1/29/08 we placed approximately 0.8 trillion gallons of waste water in
the final holdup pond for further treatment. This effluent was from one of our main chemical
treatment ponds. We attempted to release the effluent from one of our main chemical treatment
ponds through Outfall 002 and noticed trace amounts of foam being, generated during the release.
We stopped the discharge and placed the effluent in the final holdup pond for further treatment.
The final holdup pond was placed in recirculation mode for additional treatment. The effluent
released was within our discharge requirements at the tune of the event with exception of the
trace foam ;generation.
On 1/08 the final holdup pond recirculation was secured. An operator thought he noticed that
the pond level had decreased. A cheek was made for leaks through the pond piping and in areas
around and below the pond. None were observed. Tape was placed on the final holdup pond
wall to denote current effluent level..

PPV
n 2/2/08 the pond level was checked to see if the level had decreased. Inconclusive as to level
drop.
n /3/08 (Sunday) the pond level was checked again by the plant's ORC and he determined that
the effluent level had dropped based on the tape marks on the side of the pond. The ORC
contacted Environmental, Health & Safety informing them of the situation. EHS determined that
the release would be reportable. Chemistry began to pump the contents of the final holdup pond
back into B treatment pond.
On /4/08John Williamson of EHS reported the release to Mr. Mike Farber of NCDENR in
Mooresville. The approximate volume of the release reported was 100,000 gallons. The
apparent release path was to the ground. EHS, Chemistry, Radiation Protection and others
attempted to determine: where the release was going, A'thorough search of the areas near and
around the final holdup pond was performed. No visible water was observed. An investigation
into how the effluent was released continues with no final determination being, made at this time.
There is not an obvious release path (large cracks, piping, etc.).
n 02/ 15/08, Chemistry revised their estimate of how much effluent was released to 140,000
gallons. McGuire EHSprovided an update to NCCDENR in Mooresville (Mr. Mike Parker) on
the increased volume of the release and that the release contained a small amount of tritium
(9,505 5 picocuries/L,). The amount of tritium is well below the Drinking Water limit of 20,000
picoc;uries/G and the CERCLA RCS of 100 curies. Tritium is an issue of concern for the nuclear
industry. Attached to this report is a document describing the tritium issue (groundwater talking
points for external stakeholders).'
The final holdup ;pond was pumpeddownas far as the installed piping would allow. Rental
pumps were then used to empty the pond as far as practical.
At this time no additional releases are occurring.
e are still trying to determine how the effluent was released. Them is approximately I foot of
sludge in the bottom of the pond. Plans are being made to remove the sludge if practical. As
soon as the sludge is removed, engineering will try to determine how the effluent escaped the
pond.
Chemistry has procedurally prohibited the use of the Final Holdup Pond until it is repaired and
verified not be to leaking.
Groundwater well samples were taken on /5/0for sulfate, nitrate, chloride and ammonia in
addition to pH, conductivity, and tritium. Once the results have been received we will
communicate the results to NCDENR in Mooresville.
Additionally, when we :have determined how the effluent from the final holdup pond was
released we will also follow-up with NCCI ENR in Mooresville,

Groundwater Talking Points for External Stakeholders
Tuesday, Feb. 5,2008
As part of the nuclear industry's groundwater protection initiative, we must activate our
communications protocol based on certain criteria. On Sunday, Feb. 3, we identified a leak from
a treated wastewater pond on the McGuire site that resulted in a release of water to the
environment. Please begin contacting your stakeholders as indicated below) at noon
today. All contacts must be made by the end of business today. Also, if any of your
contacts have changed, please let me know so we can update our plan/contact list.

related to groundwater protection, the nuclear industry has adopted an initiative to enhance
groundwater protection around all nuclear power plants.
• Each nuclear station has radiological reporting requirements included as part of its operating
license. This industry initiative is intended to supplement the existing requirements at each
nuclear station.
• Duke Energy has always maintained radiological environmental sampling and monitoring
programs that are subject to oversight by the Nuclear Regulatory Commission. These
programs sample and monitor for both off -site and on -site radionuclides,
• On Monday, Feb. 4, personnel from McGuire Nuclear Station notified the N.C. Department
of Environment and Natural Resources and the NRC that approximately 140,000 gallons of
water from a wastewater treatment pond on the site may have leaked into the ground.
• The water was being held in the pond prior to its final release in accordance with our
permits,
• We are in the process of pumping the remaining water in this pond to other ponds on site to
prevent any further releases. We will not use this pond until we understand the source of the
leakage.
• While there are no public health risks from this incident, the water did contain a very low
concentration level of tritium — approximately 9,000 picocuries/liter. This is far below the
EPA drinking water standard of 20,000 picocuries/liter.
• Tritium is found naturally in air and water, and is a by-product of nuclear reactor operations.
Tritium emits a very low level of radioactivity. It must be ingested in large amounts to pose
any significant health risks.
• A thorough and comprehensive investigation is underway. We will share more information
as it becomes available.

REPORTABLE SPILL FROM CO2 HOUSE PIT
• Asp of our on -going investigation of the release reported on 2/4/08, we have identified
a new release that appears as if it may have existed since plant start-up
This newly identified discharge is to a wooded area below the final holdup pond and was
discovered on 2/7/08
• The release is coming from our pH monitoring and adjustment system and loss of flow
indication line
• The pH monitoring and adjustment system checks the pH of the discharge flow from our
chemical treatment ponds. If the pH is out of spec, it sends a signal to stop the discharge
flow. Set points for pH are 6.2 and 8.8.
• Once the effluent has passed through the pH probe it is routed to a pipe which discharges
to a valve pit.
• The valve pit has a pipe in it that discharges to the wooded area about 300 feet from the
final holdup pond.
• This release only occurs during an effluent discharge to waste water Outfall 002
• The effluent that goes to the pipe in the woods is within release specs for Outtall 002
The release is approximately 1.3 gallons per minute, 1872 gallons per day,
• Chemistry personnel were not aware that the pit was being released to the environment
• The release has been stopped and will be re-routed to be in compliance with our NPDES
permit requirements
• This release also contains a small amount of Tritium, a radioactive isotope.
• Sampling indicates the release is below the drinking water limits for reporting.
• This release has already been reported to the NRC (Nuclear Regulatory Commission)
under our groundwater monitoring program,

Staff of the Environmental Sciences Section of DWQ have i rman Environmental
Monitoring Program: 2004 Summary Report. The report is re aired by NPDES permit number
NCO024392 for the McGuire Nuclear Station. The water chemistry, phytoplan to , zooplankton, and
fisheries data compiled in the report are within the ranges found in prior gears of the maintenance
monitoring program, so staff have no major concerns at this time.
Bryn Tracy of the Biological Assessment Unit, however, did have these comments:
Fishermen' continue to deliberately moue fish around the state. The latest example is striped mullet being
3
collected in Lake Norman. The introduction of alewife into lake Norman now influences the distribution of
r° striped bass making them more vulnerable to the habitat squeeze and die -off in mid -late summer. The
2004 kill of striped bass was well documented and explained by DPC„ NCWRC, and DWQ staff.
Although the emphasis in the monitoring program is on largemouth bass, are other species, such as
blue ill and redbreast sunfish, tracked as well (numbers, biomass, and size distributions)? Or are these
data tracked, but just not 'reported?
Page -24 -- the reservoirwide population estimates of pelagic forage fish seem to follow a "boom-
