Subject: Review of Duke Energy Carolinas, NPDES Permit NC0004987, "Assessment of Balanced and
Indigenous Populations in Lake Norman near Marshall Steam Station", October 2009.
Environmental Sciences Section staff have reviewed the subject document which was received on October 29, 2009, Eric
Fleek and Bryn H. Tracy reviewed the sections on macroinvertebrates and fish, respectively. By agreement with the
Department of Environment and Natural Resources (NCDENR), Duke Energy conducts annual monitoring of Lake
Norman in the vicinity of the Marshall Steam Station to support NPDES Permit NC0004987 (Part1.1. Effluent Limitations
and Monitoring Requirements (outfall 001) ("The Regional Administrator has determined pursuant to Section 316(a) of the
Act that the thermal component of the discharge assures the protection and propagation of a balanced, indigenous
population of shellfish and wildlife in and on the receiving body of water. Water quality temperature standards must be
maintained outside the approved 316 (a) mixing zone.)". The power plant operates under an DWQ- and EPA -approved
Clean Water Act §316(a) thermal variance. The report does fulfill the permit obligations for reporting the results of the
biological monitoring. Based on a review of the data, it is our opinion that the Marshall Steam Station is unlikely in having
an impact to the benthic macroinvertebrate and fish communities in the multi -purpose Lake Norman. We also conclude
that the two aquatic communities currently qualify as balanced, indigenous communities,
We are continuing to review the report. However, at this time we offer the following comment and requests for future
reports beginning with the 2010 report.
Comment
1, Although the fish assemblage in this multi -purpose reservoir is comprised of indigenous and nonindigenous
species (Tables 4-1 and 4-2), the fish community continues to be considered balanced and indigenous, We have
no concerns because the Clean Water Act §316(a) does allow for '°... 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 environrnental modification" (40CFR 125.71(c),
Analysis Requests
1. In addition to Tables 3-3 through 3-6, please include a taxonomic table comparing taxa occurrences for the
current sampling year for each station so that a direct side -by -side comparison can be more easily conducted,
Please see Table 1 as an example.

2. In addition to Figures 3-1 through 3-6, please include the following graphs for each station and year (in the same
format as currently presented) for the following groups: Non-Chironamid Diptera, Ephemeroptera, Plecoptera,
Trichoptera, Coleoptera, Odonata, Megaloptera, Crustacea, and Mollusca. Again, this will allow for a more direct
side -by -side comparison for each station and each taxonomic group.
In addition, EPT taxa richness and EPT density should also be reported for each station going forward. These
metrics can be reported in accordance with current graphical formats.
Upon completion of our detailed review, we will be communicating with you any additional concerns or comments that we
might have. In the mean time, if you have any questions, please do not hesitate to contact me or my staff,.

Mike,
This is a follow-up notification to my phone message left at approximately 4:59 PM of a pH measurement of a 5.79
s.u. at Marshall's outfall 002 at 4:35 PM today. Caustic addition has been initiated to adjust the pH of the effluent
to between 6.0 and 9.0 s.u, Routine in -process pH monitoring upstream and downstream of outfall 002 had
indicated no concern for additional treatment. I will be at Marshall tomorrow and plan to follow-up with you by the
end of the day. If you have further questions, I can be reached at my mobile phone number below or by email.

Per our telephone conversation, please reference the attached drawing for the proposed ash landfill
("Proposed Landfill Site #1") located within the current boundary of the active ash basin at Marshall
Steam Station, Duke Energy is considering permitting a synthetically lined industrial landfill on this
site
Duke Energy requests that this 101 acre portion of the ash basin (Proposed Landfill Site #1") be
officially removed from the active ash basin boundary This reduction in area will not compromise
wastewater treatment within the active ash basin.
If you have any concerns regarding this request, please contact me at [phone], In the
absence of any feedback from your office, we will assume that our proposed course of action is
acceptable and will initiate the landfill permitting process with the N.C, Division of Waste
Management, Thank you for your assistance on this matter.

Subject; "Brown Scum" Incident
Near Marshall Steam Station - August 18, 2007
Ms. Allocco and Mr. Pettit:
As discussed with Donna Burrell and Duane Harrell of Duke Energy's Corporate EHS
Services department during your investigation near Marshall Steam Station last
Saturday,. Duke is providing the attached discussion of the "brown scum" event and
analytical results from the sample collected. We hope that this summary helps in your
investigation and in the event there are future sightings in the coming weeks.
If you have any questions or require further detail, please feel free to give me a call at
[phone] or Duane Harrell of our Environmental Laboratory at [phone].
Sincerely,
Patrick J. McCab PE
Manager - Environmental Field Support
Duke Energy - Carolinas Generation

During late summer and early fall, people on our lakes often observe patches
of "brown scum" on the surface of the water. This is more common is coves and
near shore, but windrows of "brown foamy scum" are also observed in main lake
areas. The presence of this material is a normal event. As plants and animals go
through their normal life cycles and die, they release cell contents, including
microscopic oil droplets, and cell membranes. This material mixes with leaf litter,
fungal spores, pollen, and very small soil particles to form the brown scum. The
process may have been accelerated in certain areas of Lake Norman due to low water
levels which expose expanses of shoreline. If some perturbation occurs, such as
wave action or fluctuating water levels, fine sediments and organic matter may be
washed into the lake.
Apparently an event of this sort occurred on Saturday, 18 August. About 400-
500 mL of water was collected from the area and transported on ice to the Duke
Energy Environmental Lab. A sub -sample was examined under the dissecting
microscope (25X) and appeared to be mostly detrital material to include bits of leaf
litter, small hollow stems, some pollen grains, and very fine sediment. Another sub -
sample was examined under high power (500X) and contained high numbers of
microscopic algae, but not sufficient to be called a bloom. Most of the algae were
green algae and diatoms. Detritus, both inorganic and organic, was the most
prevalent material by far. Most of the organic material looked like deteriorating
plant matter and dead algae. The inorganic material was mostly fine sediment
particles. Further analyses were conducted to determine chlorophyll and total and
organic solids. The chlorophyll concentration was high (25.5 µg/L, or ppb), but well
below the NC limit for outfalls and blooms of 40 lag/L. Total solids content was 8.98
mg/L, while organics constituted 2.83 mg/L. These analyses tend to confirm that the
event was the result of existing localized conditions. No evidence of an oil or other
spill was observed.

Pilot Test
Dear Mr, Parker:
With reference to our recent conversation, this letter is to inform you that a pilot test is planned
to begin in May 2007 at Marshall Steam Station (MSS). This test is expected to last for at least
six months. The pilot test system is a scaled down model to simulate part of the wastewater
treatment system (WWTS) that is being put in place at Belews Creek Steam Station and also
Allen Steam Station, This WWIS's primary purpose is to treat for selenium.
The pilot system will be receiving approximately 1 to 2 gpm of waste water from MSS's Flue
Gas Desulfurization WWTS. This wastewater will then be sent through the pilot system. The
treated water will then be returned to the on -site WWTS sump, This sump discharges to the
front of the WWTS. The 1 to 2 gpm treated flow from the pilot system is very small in
comparison to the expected flow of 538 gpm being treated by the full scale WWTS,
There should be no adverse impacts to the MSS WWTS due to the operation of this pilot system,
If you need additional please contact me at 704 382-4669lf you would like to see the pilot test
in operation please let me know.

Dear Mr. Pollack:
Recently you were sent a letter from the Division of Land Resources (DLR) indicating that
the Sedimentation and Erosion Control Plan for the subject development had been approved.
Accompanying the DLR letter was NPDES General Stormwater Permit No. NCG010000, which
authorizes you to discharge stormwater to the surface waters of North Carolina from point source
discharges associated with construction activities including clearing, grading, and other land
disturbing activities. The purpose of this letter is to advise you of the importance of the General
Permit and the liabilities in the event of failure to comply with the terms and conditions of the
Permit. If you have not already done so, it is suggested that you thoroughly read the permit. Of
particular importance are Parts I and II of the permit.
Parts I and II set forth the minimum visual monitoring and reporting requirements for your
s(ormwater discharge. In particular, Part I, Section B describes the visual monitoring frequencies
and locations, the requirement to maintain a rain gauge onsite, and the need to maintain a written
record of all inspections. Upon commencement of your land disturbing activity, you must initiate the
visual monitoring and record keeping requirements in this permit. The visual monitoring data results
must be maintained on -site and made available to a DWQ representative upon request. The
retraining parts of the Permit set forth definitions, general conditions and special conditions
applicable to the stormwater discharge(s). The conditions include special reporting requirements in
the event of noncompliance, bypasses, treatment unit/process failures, etc.

EXECUTIVE SUMMARY
• Per agreement with the North Carolina Department of Environment, and Natural
Resources (NCDENR), annual physicochemical monitoring, and assessments of
macroinvertebrate and fish populations at selected locations in Lake Norman
continues. This report presents data collected from 1999 through 2003. Results of
data analyses completed since submittal of the previous report in 1999 are reported
and support renewal of the existing permitted thermal limits for Marshall Steam
Station (MSS).
• MSS operated continuously from 1999 through 2003, and station operation during
this period was similar to previous years. MSS operated at an average capacity of
77% over the five-year period. Monthly average discharge water temperatures at
MSS were in compliance with NPDES permitted thermal limits of 93.9 °F (34.4 °C)
July 1 through October 31, and 91.9 °F (33.3 °C) the rest of each year, over this five-
year period.
• The macroinvertebrate data exhibit substantial variability; however, the variability is
consistent with that observed for historical data. The data for the current study
exhibit the same general density and taxa diversity trends noted during the previous
study period. Current study results indicate that the macroinvertebrate densities and
taxa diversity observed during 1999 — 2003 at locations uplake, downlake and in the
vicinity of MSS are indicative of balanced and indigenous macroinvertebrate
communities in these locations.
• A diverse fish community was present in the littoral portions of Lake Norman around
MSS. The fish community encompasses a range of trophic groups including
planktivores, insectivores, omnivores, and piscivores.
• The MSS discharge area of Lake Norman typically yielded more fish than adjacent
regions of Lake Norman. The higher fish abundance in the MSS discharge during
summer is likely due to generally higher nutrient concentrations at uplake locations
and several other specific factors, including water temperatures close to ambient
temperatures, flowing water, and rip -rapped shoreline, as opposed to the bare clay
bank shorelines of other locations.
i

• Fish health assessment scores on Lake Norman indicate that largemouth bass and
their local aquatic environment are not experiencing atypical levels of stress.
• Lake Norman forage fish populations have been dynamic during the past few years.
The introduction of alewife and most recently, blueback herring Alosa aestivalis has
resulted in some alterations in the forage community. Despite the change in the
species composition of the forage community and the inherent variability of clupeid
populations over time, population estimates have been fairly stable. Forage fish
densities in Lake Norman are similar to those noted in other Catawba River reservoirs
of similar trophic status.
• Based on the diversity and biomass of the Lake Norman littoral fish community, the
abundance of fish in the MSS discharge canal, the good health of largemouth bass
throughout Lake Norman and specifically in the MSS discharge canal, and the
abundance of forage fish available to limnetic predators, it is concluded that the
thermal regimes resulting from the operation of MSS have supported the protection
and propagation of a balanced and indigenous fish community in Lake Norman.
• Comparison of MSS operation and environmental monitoring data indicate that
balanced and indigenous populations continue to exist in Lake Norman in the vicinity
of MSS. This supports a conclusion that the present thermal limits should be
maintained when the Station NPDES permit is renewed.

CHAPTER 1
INTRODUCTION
Per agreement with the North Carolina Department of Environment, and Natural Resources
(NCDENR), annual physicochemical monitoring, and assessments of macroinvertebrate and
fish populations at selected locations in Lake Norman continues (Table I-1 and Figure 1-1).
Physicochemical and biological data are collected at five locations near Marshall Steam
Station (MSS) and include an upstream, background site (location A), two sites within the
immediate projected impact of MSS's discharge (locations B and C), and two downstream,
recovery sites one of which represents an area of the lake that is expected to be minimally
impacted by the discharge (location D), and the second (location E) representing a downlake
area presumably outside the influence of the effluent plume.
The objective of this on -going monitoring program is to provide an assessment of the
balanced and indigenous nature of the biological populations in Lake Norman with respect to
operation of MSS, and evaluate renewal of thermal limits in the Station NPDES permit
(NC0004987). The thermal limit for MSS is a monthly average discharge (i.e., end -of -pipe)
temperature limit of 93.9 °F (34.4 °C) during July 1 through October 31, and 91.9 °F (33.3 °
C) the rest of each year.
Review of past studies by regulators have determined pursuant to Section 316(a) of the Clean
Water Act that the thermal component of the discharge of MSS assures the protection and
propagation of balanced, indigenous populations in Lake Norman. This report presents data
collected since submittal of the previous summary reports (Duke Power 1994, 1999) and
includes data collected from 1999 through 2003. These data were also compared with other
past and present on -going environmental monitoring programs conducted in this watershed.

CHAPTER 2
STATION OPERATION
BACKGROUND INFORMATION
Marshall Steam Station (MSS) is located on the western shore of Lake Norman (Figure 1-1),
just north of Charlotte, North Carolina, in Catawba County. Its four generating units have a
combined operating capability of 2090 MWE-net. Units 1 and 2 are each rated at 385 MWE-
net and began commercial operation in 1965 and 1966, respectively. Units 3 and 4 are each
rated at 660 MWE-net and began commercial operation in 1969 and 1970, respectively.
MSS receives once -through condenser cooling water (CCW) from below a skimmer wall
located at the end of a 1.3-mi (2.1-km) long cove. The cove's surface area is about 200 acres
(81 ha) and its volume is approximately 250 million ft3 (7 million m3). The skimmer wall
was designed to retain the upper 60 ft (18.3 m) of water on the lake side of the wall at full
pond. The opening below the skimmer wall through which the station CCW is withdrawn, is
about 10 ft (3 m) deep and 270 ft (82.3 m) wide.
Units 1 and 2 each have two condenser cooling water pumps and Units 3 and 4 each have
three condenser cooling water pumps. Typically, only one pump per generating unit is used
during the cool winter months or when the unit is operating at reduced load. During the
warmer summer months when units are operating at full -load, either two or three pumps are
generally used depending on which units are operating. Maximum rates of cooling water
flow are 423 cfs (11.8 cms) each for Units 1 and 2, and 709 cfs (19.9 cms) each for Units 3
and 4. Thus, the maximum possible station CCW flow rate is 2264 cfs (63.4 cms). Under
one pump/unit operation, the maximum CCW flow rate for the entire station is 1,230 cfs
(34.4 cms). Refer to Table 2-1 for a listing of CCW flow rates for each unit under one-,
two-, and three -pump operation.
The condenser cooling water from MSS is discharged into a one -mile long cove. The
discharge cove spreads from a width of 75 ft (22.9 m) and depth of 33 ft (10.1 m) at the
discharge structure, to a width of 850 ft (259.1 m) and a depth of 50 ft (15.2 m) at the mouth
of the discharge cove. The total area of the discharge cove is about 75 acres (30.4 ha).

Lake Norman can be classified as oligotrophic, or nutrient poor, based on year 2002
assessments performed by the State in association with the Lake Assessment Program, which
is conducted on a five-year cycle (NCDENR 2003). Nutrients and chlorophyll a values were
consistently either low or less than the laboratory reporting limits for the specific analyte,
whereas metal concentrations were within applicable water quality standards. Elevated
levels of surface dissolved oxygen concentrations and dissolved oxygen saturation values
were observed in the upper, riverine section of the reservoir. These observations are similar
to results reported by Mecklenburg County Department of Environmental Protection for
lower Lake Norman (MCDEP 2003), and to that reported by Duke Energy for year 2002, and
earlier; based on water quality sampling of Lake Norman associated with NPDES
requirements for McGuire Nuclear Station (Duke Power 1995, 1996, 1997, 1998, 1999b,
2000, 2001, 2002, 2003).
THERMAL DATA
Marshall Steam Station is operated by Duke Power as a base -load generating facility, and
station operation during the period January 1999 through December 2003 was similar to
previous years. MSS operated continuously from 1999 through 2003 with peak pumping of
condenser cooling water during the summer. Electric generation, expressed as monthly
average percent capacity, ranged from a minimum of 38% in November 1999 to a maximum
of 98%, measured in December of 2001 and 2003. MSS operated at an average capacity of
77% over the five-year period.
The seasonal cycle of discharge water temperatures at MSS over the period January 1999
through December 2003 was similar to that observed in previous years (Figure 2-1; Duke
Power Company 1994, 1999). Monthly average discharge water temperatures at MSS were
in compliance with NPDES permitted thermal limits of 93.9 °F (34.4 °C) July 1 through
October 31, and 91.9 °F (33.3 °C) the rest of each year, over this five-year time period
(Figure 2-1). Discharge water temperatures ranged from a minimum monthly average of
71.2 °F (19.6 °C) in January 2001 to a maximum monthly average of 93.4 °F (34.1°C) in
September 2002 (Figure 2-1). Average daily discharge temperatures ranged from a
minimum of 54.8 °F (12.6 °C) in January 2003 to a maximum of 99.7 °F (37.6 °C) in
September 1999 (Figure 2-1). Discharge temperatures are linked to a combination of local
meteorological conditions, and electrical generation.

CONCLUSIONS
MSS operated continuously from 1999 through 2003, and station operation during this period
was similar to previous years. Electric generation, expressed as monthly average percent
capacity, ranged from a minimum of 38% in November 1999 to a maximum of 98%,
measured in December of 2001 and 2003. MSS operated at an average capacity of 77% over
the five-year study period. Monthly average discharge water temperatures at MSS were in
compliance with NPDES permitted thermal limits of 93.9 °F (34.4 °C) July 1 through
October 31, and 91.9 °F (33.3 °C) the rest of each year, over this five-year period.

CHAPTER 3
MACROINVERTEBRATES
METHODS AND MATERIALS
Benthic macroinvertebrate sampling was conducted annually in late July of each year from
1999 — 2003 as part of the continuing monitoring program for Marshall Steam Station
(MSS). As in previous years, samples were collected from Lake Norman uplake of MSS
(Location A), near the MSS discharge canal (Location B), mid -lake near MSS (Location D),
and further downlake (Location E) (Table 1-1 and Figure 1-1). A ponar dredge was used to
collect five sample replicates at each location. Samples were collected at depths ranging
from 2-3 m to bracket the depth of peak benthic abundance (Brinkhurst 1974). Samples were
washed through a 500-µm mesh sieve and preserved individually with 70% ethanol
containing rose bengal stain. The substrate of each replicate was identified, based on a visual
analysis of substrate types during the sieving process, and the resulting data was recorded.
Organisms were sorted in the laboratory and identified to the lowest practical taxon.
Macroinvertebrate densities were calculated by extrapolating ponar densities to a standard 1
m2 bottom area. The assessment of the balanced and indigenous nature of the benthic
community was determined by comparing macroinvertebrate densities and taxa abundance
among the sample locations uplake, downlake, and near the MSS discharge canal.
RESULTS AND DISCUSSION
Substrate
Typically, the substrate was similar at all locations, being composed primarily of silt, sand,
and organic matter (om). Clay was observed in the substrate at Location A in 1999 and
Location E in 2002 and 2003 (Table 3-5).
Density
During 1993 — 2003, overall mean macroinvertebrate densities varied substantially among
years, locations and replicates within locations (Figure 3-1). The observed variability in
Lake Norman macroinvertebrate data is fairly indicative of the inherently variable nature of
3-1

reservoir macroinvertebrate data. It is typical to observe substantial temporal and spatial
variability for these types of data. It is also important to note that there can be substantial
variability in density data among replicates at the same location, as indicated by the density
range bars in Figure 3-1. This within location variability is an important consideration when
comparing density data among years and locations and assessing community changes relative
to natural variability.
During the current study period, 1999 — 2003, Location D had the highest overall mean
macroinvertebrate density, followed by Locations A, E, and B. The mean annual
macroinvertebrate density at Location A ranged from 1,811/ m2 in 1999 to 6,157/ m2 in 2002.
Densities at Location B ranged from 1,534/m2 in 2002 to 4,677/m2 in 2001.
Macroinvertebrate densities at Location D ranged from 2,797/m2 in 2002 to 7,483/m2 in
2001, the highest density of macroinvertebrates collected during the 1999 — 2003 study
period. Macroinvertebrate densities at Location E ranged from 1,294/m2 in 2002, the lowest
density recorded during the 1999 — 2003 study period, to 6,348/m2 in 1999.
Taxa
As during previous study years, taxa abundance during 1999 — 2003 varied by year and
location (Tables 3-1 through 3-4 and Figure 3-2). Taxa abundance was greatest in 2003,
when all four locations exceeded the number of total taxa collected in eight years. Overall
taxa abundance was lowest in 2002, when Location B had 17 taxa. It is important to note
that Oligochaeta were not identified to species prior to 2000 and adding species
identifications in 2000 — 2003 increased total taxa abundance. The average number of total
taxa collected at each location during 1999 — 2003 was comparable to previously reported
data from 1996 — 1998. With the exception of 2000 results, macroinvertebrate diversity
declined slightly from Location A to Location B, and then generally increased further
downlake.
During 1999 — 2003, samples were comprised primarily of Oligochaeta, Diptera, and
Corbicula (Figures 3-3 through Figure 3-6). As observed with overall densities, Oligochaeta,
Diptera and Corbicula densities varied by location and year. At Locations A and B,
Oligochaeta and Diptera taxa dominated the collections. Corbicula collections at Location B
were extremely low during all years of the study period. At Location D, Corbicula generally
dominated the collections, while Diptera and Oligochaeta abundances were lower and
3-2

alternated in abundance each year of the study period. Location E collections were
dominated by Corbicula in 1999, then Oligochaeta and Diptera taxa from 2000 — 2003.
CONCLUSION
As noted in the Results and Discussion section, the 1999 — 2003 macroinvertebrate data
exhibit substantial variability; however, the variability is consistent with that observed for
historical data. The data for the current study exhibit the same general density and taxa
diversity trends noted during the previous study period of 1996 —1998. Current study results
indicate that the macroinvertebrate densities and taxa diversity observed during 1999 — 2003
at locations uplake, downlake and in the vicinity of MSS are indicative of balanced and
indigenous macroinvertebrate communities in these locations.

CHAPTER 4
FISH
METHODS AND MATERIALS
Summer Electrofishing
Fish were collected from Lake Norman near Marshall Steam Station (MSS) in July, 2000 —
2003, using a boat -mounted electrofisher during daylight hours. Two netters collected all
stunned fish. Fish were identified to species and measured for total length (TL, mm) before
being returned to the lake.
Sampling locations consisted of one location uplake from the MSS intake (Location A), two
locations in the discharge canal (Locations B and C), and two locations downstream from the
MSS discharge (Locations D and E, Table 1-1 and Figure 1-1). Shoreline segments of 328 ft
(100 m) were electrofished on the left and right banks at each cove location. The number of
species and catch per unit effort (CPUE, number of fish/328 ft) were calculated for each
sampling location. Water temperature (°F and °C) and dissolved oxygen concentration
(mg[L) were measured with a calibrated thermister and dissolved oxygen probe, respectively,
at each location.
Summer electrofishing samples are part of the required MSS 316(a) annual monitoring
program. Spring electrofishing, fish health assessments, and hydroacoustic surveys on Lake
Norman are part of Catawba-Wateree Hydro relicensing activities. These additional
sampling protocols provide information relative to potential MSS impacts and data are
included here to further assess the balanced and indigenous nature of the Lake Norman fish
community.

Fish were collected during daylight hours with a boat -mounted electrofisher from Lake
Norman in April or May, 2000 — 2003, when surface water temperatures ranged from 59 to
68 °F (15 to 20 °C). Two netters collected all stunned fish and all fish collected were
identified, sorted, counted, and weighed in aggregate by species and then returned to the lake.
Water temperature (°F and °C) was measured with a calibrated thermistor.
4-1.

Ten 984 ft (300 m) shoreline transects were sampled during daylight in the vicinity of MSS
and at a reference location midway between MSS .and the McGuire Nuclear Station (MNS)
(Figure 4-1). All transects were subjectively selected to include the various shoreline habitat
types that exist in Lake Norman. The only areas excluded were shallow flats where the
electrofishing boat could not get within 10-13 ft (3-4 m) of the shoreline. Catch, biomass, and
number of species/9,843 ft (3,000 m) were calculated for each sampling location.
Fish Health Assessment
The health of largemouth bass was assessed at 27 locations throughout the Catawba River,
including four Lake Norman locations, during October 2000 and 2003 (Figure 4-1). The four
Lake Norman locations were: the vicinity of Lake Norman State Park (Zone 5), the MSS
discharge canal (Locations B and C), a midlake location (in the same area as the spring
electrofishing reference location in Zone 3), and the MNS discharge canal (Zone 1). Fifteen
largemouth bass between 10 and 18 in (250-450 mm) TL were collected by electrofishing at
each location, fatally anesthetized, and autopsied by the Fish Health Assessment Index
methods of Coughlan et al. (1996). Bass tissues, organs, and blood were evaluated and
scored for deviations from normal appearances or values. Scores for the 15 bass were
averaged to arrive at a fish health assessment score for each location. Higher location scores
indicate relatively poorer fish health.
Hydroacoustic Surveys
Mobile hydroacoustic surveys of the entire lake and its major tributaries were conducted at
night during September, 2000 — 2003, to estimate forage fish populations. Surveys typically
covered the region from the Cowans Ford Dam to the region just north of the SR 1004 bridge
(a distance of approximately 25.4 river miles) and included Ramsey, Davidson, and
Mountain Creeks. Lake Norman was divided into six zones to more accurately account for
spatial heterogeneity in water quality and fish productivity (Figure 4-1).
Hydroacoustic surveys employed a multiplexing 200-kHz digital transducer system. This
multiplexing system consisted of a side -scan split beam transducer (sampling the top 6.5 ft (2
m) of •the water column) and a down -looking dual -beam transducer (sampling from 6.5 ft (2
m) below the surface to the bottom) to detect surface -oriented and deeper fish, respectively.
The transducer system was periodically calibrated using US Navy standards at the BioSonics
4-2

Laboratory, Seattle, Washington. The transducer system was also standardized prior to each
acoustic sample with a tungsten carbide reference sphere as a standard target. Individual
forage fish targets were used to generate average back -scattering cross -sections (target
strengths). Returning voltages were scaled by the average back -scattering cross-section and
processed via echo integration for generation of fish densities. The average fish density was
calculated at 1/4-km intervals and processed by bootstrap procedures to generate average fish
densities in each of six zones in Lake Norman (Provalis Research 2002). Yearly forage fish
population estimates for Lake Norman were the sum of fish densities for a particular zone
multiplied by that zone's surface area.
Purse seine samples were collected at night during September, 2000 — 2003, to determine
species composition and size distribution of forage fish `counted' by hydroacoustic
techniques. The purse seine measured 400 x 30 ft (118 x 9 m) with a 3/16 in (4.8-mm) mesh
and samples were taken from three areas of Lake Norman (Figure 4-1). These areas included
mid -channel locations near the Lake Norman State Park (Zone 5), the mouth of Davidson
Creek (Zone 2), and the forebay of Cowans Ford Dam (Zone 1) that are approximately 19.8,
5.5, and 1 river miles uplake from the Cowans Ford Dam, respectively.
Balanced and Indigenous Assessment
The assessment of the balanced and indigenous nature of the fish community in Lake
Norman included a comparison of species numbers and CPUE data from locations upstream
of, downstream of, and in the discharge canal from MSS during summer electrofishing.
Similar type comparisons were made with spring electrofishing data. Additionally, the fish
community around MSS was evaluated for the health of largemouth bass and the
sustainability of the forage fish population over time.
RESULTS AND DISCUSSION
Summer Electrofishing
The number of species and CPUE during summer electrofishing at all locations around MSS
ranged from four to nine and from 11.0 to 143.5 fish/328 ft, respectively, from 2000 to 2003
(Tables 4-1 to 4-4). The number of fish species present at each of the two discharge
locations (Locations B and C) varied, and was not consistently the highest nor lowest of the
4-3

locations sampled. The combined annual species composition in the vicinity of MSS was
typically dominated by centrarchids, followed by cyprinids. Centrarchids comprised from
64.5 (2001) to 90.6 % (2003) of the fish community around MSS. Clupeids, percids, and
ictalurids were minor contributors to the species assemblage.
During 2000 and 2002, the highest CPUE was measured in the MSS discharge at Location C
(Figure 4-2). The highest CPUE during 2001 and 2003 was measured downlake at Location
E. In all four years of sampling, the highest, or second highest, CPUE was measured at one
of the two discharge canal locations despite the fact that these two locations typically had the
highest water temperatures and the lowest dissolved oxygen concentrations. Electrofishing
catch rates typically are influenced by a range of variables including productivity, gear
efficiency, bottom substrate, available cover, turbidity, water temperature, and water
velocity. The higher CPUE in the MSS discharge during summer is likely due to several of
these factors, including water temperatures close to ambient temperatures, flowing water, and
rip -rapped shoreline (Location C), as opposed to the . bare clay bank shorelines of other
locations. Summer electrofishing results observed from 2000 — 2003 are similar to those
demonstrated in previous reports from 1991 —1999 (Duke Power 1994, 1999).
Spring EIectrofishing
Fish numbers and biomass per 9,843 ft of shoreline ranged from 1,157 to 3,277 and 80.4 to
387.3 kg, respectively, in the vicinity of the MSS discharge and from 1,314 to 2,349 and 81.1
to 115.4 kg, respectively, at the reference location (Table 4-5 and Figure 4-3). High spring
2003 rainfall totals elevated lake levels and inundated shoreline vegetation, providing the
appropriate cues to trigger common carp Cyprinus carpio spawning near MSS. The resulting
high biomass measured (387.3 kg in 2003) can be attributed to the collection of 141 common
carp weighing over 255 kg. The average numbers of fish and biomass collected around the
MSS discharge were typically greater than those from the downlake reference location.
The average number of fish species collected was also typically greater at MSS than the
reference location. A total of 28 species and hybrid lepomids were collected near MSS from
2000 to 2003 while 27 species and hybrid lepomids were collected at the reference location
(Table 4-6). Spring electrofishing data indicate that the region of Lake Norman near the
MSS discharge yielded more species and numbers of fish, resulting in higher fish biomass
than the downlake reference location. Declining nutrient concentrations with increasing
proximity to the Cowans Ford Dam is probably one of several factors that contributed to the
4-4

reduced fish biomass observed downlake. Species composition information from all the
spring electrofishing samples indicates that centrarchids dominate the Lake Norman fish
community (65.9% of all fish collected) followed by cyprinids, clupeids, ictalurids,
moronids, percids, catostomids, lepisosteids, and salmonids. The salmonids are undoubtedly
the remnants of bait bucket releases by striped bass fishermen. Species composition
information from spring electrofishing is comparable to that found around MSS during
summer electrofishing though a larger variety of species inhabit the shoreline in spring
compared to summer.
Fish Health Assessment
Fish health assessment scores for Lake Norman largemouth bass ranged from 18 to 30 from
2000 to 2003 (Table 4-7). Scores for the entire Catawba River ranged from 8 to 48 and
averaged 23.9 (2000) and 30.3 (2003) (Duke Power, unpublished data). Largemouth bass are
one of several top predators in the Lake Norman food chain and integrate the effects of
various stressful physical, chemical, and biological conditions. Experience has demonstrated
that scores greater than 45 identify areas where the integration of these stressful conditions
may be a cause for concern and further studies. All Lake Norman fish health scores were less
than 45 and all MSS scores were generally less than, or equal to, the average for the entire
Catawba River. The health of largemouth bass residing in the vicinity of MSS is good and
generally similar to that of bass from other regions of Lake Norman.
Hydroacoustic Surveys
Purse seine sampling at three Lake Norman locations identified threadfin shad as the
dominant forage species from 2000 to 2003 (Table 4-8). Prior to 2000, threadfin shad
comprised from 99 to 100% of the forage fish population collected. Angler introductions of
alewife Alosa pseudoharengus in 1999 have gradually changed the forage fish species
composition and now roughly 20% of the forage is alewife. Alewife persistence in the
reservoir will be a continued focus of future studies. The modal size class of threadfin shad
rose briefly in 2000 and 2001, into the 50-60 mm TL range, and now appears to be in the 40-
50 mm size range (Figure 4-4).
Forage fish densities (no.lhectare) in the six zones of Lake Norman ranged from 1,800 to
13,158 during 2000 to 2003 (Table 4-9). With the exception of 2000, threadfin shad
densities were generally highest uplake in Zone 5 and lower downlake. The limited amount
4-5

of 'sampleable' habitat in Zone 6 (the most uplake zone) complicate discussions about this
trend; during the drought year of 2002 water depths were insufficient to safely lower the
transducers and collect data in this zone. Higher densities of forage fish in uplake regions
have been demonstrated previously in Lake Norman (Siler et al. 1986) and in Missouri
reservoirs (Michaletz and Gale, 1999) and are related to higher nutrient concentrations in
these regions. Forage fish densities in Lake Norman are similar to those noted in other
Catawba River reservoirs of similar trophic status.
Forage fish population estimates ranged from approximately 64.3 million to 85.7 million
during 2000 to 2003. These estimates have been fairly constant since 1997 and average
approximately 76 million fish.
CONCLUSION
A diverse fish community was present in the littoral portions of Lake Norman around MSS.
From 2000 through 2003, summer electrofishing produced 17 species of fish representing
seven families. Centrarchids numerically dominated fish populations here, followed
generally by cyprinids, percids, moronids, catostomids, ictalurids, and clupeids. A similar
species composition trend was found during spring electrofishing when 28 species
representing nine families were collected. These families encompass a range of trophic
groups including planktivores, insectivores, omnivores, and piscivores.
The MSS discharge area of Lake Norman typically yielded more fish than adjacent regions of
Lake Norman. Electrofishing CPUE indices, both numeric (spring and summer) and
gravimetric (spring), were usually higher around the MSS discharge than in adjacent lake
areas. In general, higher nutrient concentrations in the uplake regions of Lake Norman
probably contribute to the higher CPUE near MSS. The higher CPUE in the MSS discharge
(Location C) during summer is likely due to several other specific factors, including water
temperatures close to ambient temperatures, flowing water, and rip -rapped shoreline, as
opposed to the bare clay bank shorelines of other locations.
Largemouth bass are one of several top predators in Lake Norman; through diet and the
aquatic environment, they integrate the effects of various stressful physical, chemical, and
biological conditions. The fish health assessment index is a survey tool employed to identify
fish populations succumbing to undue levels of stress. The lack of elevated fish health
4-6

assessment scores on Lake Norman indicates that largemouth bass, their prey items, and their
local aquatic environment are probably not experiencing levels of stress beyond that
experienced in some Catawba River reservoirs that do not receive heated effluent.
Lake Norman forage fish populations have been dynamic during the past few years. The
introduction of alewife (and most recently, we have collected blueback herring Alosa
aestivalis) has resulted in some alterations in the forage community and will be the focus of
continued studies. Forage fish population densities, as measured by hydroacoustics, were
generally greatest in uplake portions of Lake Norman. Despite the change in the species
composition of the forage community and the inherent variability of clupeid populations over
time, population estimates have been fairly stable. Threadfin shad and alewife in Lake
Norman have consistently provided forage, though now more diverse in size and habitat
utilization, to limnetic predators.
Past studies have indicated that there is "a balanced and indigenous fish community in Lake
Norman" (Duke Power Company 1994, 1999). The present study reinforces that conclusion.
Based on the diversity and biomass of the Lake Norman littoral fish community, the
abundance of fish in the MSS discharge canal, the good health of largemouth bass throughout
Lake Norman and specifically in the MSS discharge canal, and the abundance of forage fish
available to limnetic predators, it is concluded that the thermal regimes resulting from the
operation of MSS have supported the protection and propagation of a balanced and
indigenous fish community in Lake Norman.

Hello Ron,
A review of the submitted data from the sawdust study shows that the
addition of sawdust does not cause any increase in the effluent values
for TSS or BOD5. Based on that data, effluent monitoring for those two
parameters can be discontinued during future addtions of sawdust to the
condenser tubes.
However, if the quantity of sawdust added should be greater than the
highest value of 300 lbs noted in the data, DWQ recommends that the pre
and post monitoring for TSS and BODS be reinstated.
Please contact me if any additional questions.

Mike,
Per my phone mail message, I'm forwarding monitoring results that were
collected when sawdust was used to plug small condenser tube leaks until
repairs could be done during an outage. Currently Unit #1 at Marshall
Steam Station has some small tube leaks. As currently permitted, Duke
plans to add sawdust to the CCW system to plug the small leaks, but would
like to do so without having to do pre and post monitoring, as required
previously. The attached document contains the results of the samples
collected during previous sawdust additions. As you can see, no apparent
significant impact occurred from the sawdust addition to the station
discharge Please advise, if addition of sawdust can proceed without
monitoring.

SECTION
With reference to the proposed subject NPDES permit modification, Duke Energy Corporation
(Duke) offers the following comments.
The modified NPDES permit includes weekly monitoring for the influent and effluent of the new
internal waste water treatment system (WWTS) and also weekly monitoring at the current
WWTS (outfall 002) for several new parameters. Duke requests that the monitoring frequency
be revised from weekly to monthly for the new identified NPDES parameters and also that the
monitoring requirements for the influent to the new WWTS be eliminated.
Duke plans to install a constructed wetland waste water treatment system in order to treat the flue
gas desulfurization (FGD) waste water. The pilot study being conducted at Clemson University
indicates that this treatment system will sufficiently remove targeted pollutants. Additionally,
once the new WWTS is installed and in operation, Duke plans to conduct in -process monitoring
in order to ensure that the system is operating as designed. This monitoring will focus on several
of the parameters that are identified in the proposed NPDES permit, in addition to other
performance parameters as determined by the system designer.
Additional comments on the subject permit are as follows:
1. It is requested that page numbers be included.
2. It is requested that the page for outfall 004 follow the page for outfall 003.
3. Under the "NOTES" for outfall 004 it is requested that a statement be inserted that the
submittal of monthly DMRs is only required once the FGD system begins operation. This will
reduce the paper work until the operation begins.
www.dukepower.com

4. On the page entitled "3. Effluent Limitations and Monitoring Requirements Outfall 002", in
the first paragraph it states that outfall 002 is an "internal" outfall. This outfall is actually a
"final" outfall. Therefore, it is requested that "internal" be replaced with the word "final".
5. Under Part I. item 7., the word "flue" is misspelled.
6. Under Part I. item 11., the wording used in other NPDES permits provides further
clarification on when the Biocide Worksheet 101 is not required. The current wording in other
NPDES permits states," Completion of Biocide Worksheet Form 101 is not necessary for those
outfalls containing toxicity testing. Division approval is not necessary for the introduction of a
new biocide into an outfall currently being tested for toxicity." It is requested that this wording
be included in the NPDES permit for Marshall Steam Station.
7. Under Part I. item 13., "Buck Steam Station is referenced instead of "Marshall Steam
Station". It is requested that the reference be changed to "Marshall Steam Station".
8. Under Part I. item 16. (7), the word "Minimum" should actually be changed to "Maximum".
This restricts the chemical cleaning from being diluted and suspending the metals during a
chemical metals cleaning.
9. In Parts II and IV references are made to municipalities. This new wording does not apply to
Marshall Steam Station since it is not considered a municipality. In order to minimize some
potential misinterpretations, it is Duke preference that the paragraphs that refer to municipalities
be deleted.
Duke appreciates the opportunity to review and provide comments on this proposed permit
modification. We will be glad to meet and discuss any items that you would like to discuss
further. If you need additional information or have any questions please contact Robert Wylie at
[phone].

Dead fish were observed in the Marshall intake canal early on 9/5/01. Initial estimates on 9/5/01
indicated that 15 to 20 dead stripers and about one hundred smaller fish were dead and drawn by the
intake to the intake structure.
A more definitive estimate was made on 9/6/01 from a boat launched in the intake cove. This was
reported to Mr. Scott Van Horn of the NC Wildlife Resources Commission:
Mr. Scott Van Horn and others:
Made a trip up to Marshall Steam Station intake cove on Sept 6 to get a better handle on the report of
dead fish. They counted and measured 25 striped bass (average length 541 mm , ranged from 380 to
685 mm), 1 carp (320 mm), 1 blue catfish (550 mm), 1 channel catfish (440 mm). By far, alewife were
most numerous. It was estimated to be 2 to 3 thousand fish, average length 140 mm. They didn't
take time to count them along the entire shore but estimated several sections at about a fish per foot
of shoreline with higher numbers in areas where fish had been wind rowed or sucked into the intake
bays. Striper mortalities have been seen in the intake in years past but this is a first for the recently
"introduced" alewife.
Mr. Van Horn notified the Mooresville NC DENR office on Sept. 6.
Additional Comments:
Susan Robinson and Bob Caccia talked with Mike Parker concerning the dead fish on Sept 7.

Any water pollution control system subject to classification under Rule .0302 of this Section,
utilizing a physical / chemical process to enhance an activated sludge or fixed growth process,
shall not be subject to additional classification. Rule 15A NCAC 8G .0306(d)

in Terrell, North Carolina.
As is normal procedure, the Application and accompanying attachments have been sent to
John Morris, Director of the Division of Water Resources, who then distributes the
Applications to the appropriate regional DENR office for review. However, because you have
been identified through Duke Energy's other recent Applications to be the appropriate regional

As you may recall, you processed and certified the Application for Certification of Pollution
Control Facility covering the 1996 "A" Ash Line Addition to Marshall Steam Station, which is
comparable to the 1999 "D" Ash Line for which Duke Energy is currently seeking
certification. For your reference, the "A" Ash Line Tax Certification TCS-MV-021 was

Re: Request for North Carolina DENR Certification under the IRS' Rapid Tax Amortization
Program for 1999 Additions at the Marshall Steam Station
Dear Mr. Morris:
Pursuant to the regulations included in Part 20, Chapter 1, TitIe 40, Code of Federal Regulations
(40 CFR) and Section 1.169 of the Income Tax Regulations, Part 1, Subchapter A, Chapter 1,
Title 26, Code of Federal Regulations, please find attached the completed copies of the United
States Environmental Protection Agency's (U.S. EPA's) EPA Form 3300-1, Application for
Certification of Pollution Control Facility, and accompanying attachments, covering the 1999
ash line system addition to Duke Energy Corporation's Marshall Steam Station, located in
Terrell, North Carolina, for tax purposes. The North Carolina Department of Environment &
Natural Resources' (DENR's) completion of the State Certification Form included within these
applications is required as a process step in the Internal Revenue Service's Rapid Tax
Amortization Program outlined under section 169 of the Internal Revenue Code.
As the tax treatment under the IRS's Rapid Tax Amortization Program is applicable to facilities
which "remove, alter, dispose of, store, or prevent the creation of pollutants, contaminants,
wastes, or heat," and as the ash line is encompassed within this definition, the facility addition
meets the 40 CFR criteria for a pollution control facility.
The original application and accompanying attachments have been submitted to:
Ms. Marsha English
Region IV, U.S. EPA
Atlanta Federal Center
61 Forsyth Street, SW
Atlanta, GA 30303-3104
Per the 40 CFR, you should forward one of the two copies of this application and a completed
State Certification Form to the U.S. EPA Regional Administrator at the address listed above, and
a copy of the completed State Certification Form to Duke Energy Corporation. You may send
the completed certification to my attention at the address listed here.

If you have any questions regarding this application or information supplied with this
application, please contact me at • [phone] or Ms. Kathryn Tronsberg of
Deloitte & Touche at [phone].

The above referenced permit expires June 30, 2000. GS 143-215.1(c) and Part II.B.10 of the subject permit
requires the submittal of an application for renewal at least 180 days prior to expiration.
Please find enclosed in triplicate. the application for renewal of the subject permit pursuant to 15 NCAC
2B.0105(b). The following is requested:
• notification that the application is complete
• delete monitoring of pH levels and manganese concentrations at outfall 001, since these levels reflect
those observed in Lake Norman water samples collected from 60 feet below full pond (condenser
cooling water is withdrawn from Lake Norsuun between 60 and 70 feet below full pond into the
Marshall Steam Station intake cove)
• per previous discussion with NCDENR. change the thermal limit wording in the outfall 001 page of
the permit to reflect compliance reporting in October by stating "the thermal limit is a monthly
average discharge temperature limit of 93.9°P (34.4°C) July 1 through September 30, and 9I.9°F (33.3
°C) the rest of each year" instead of "the thermal limit is a monthly average discharge temperature
limit of 93.9°F (34.4°C) July 1 through October 15. and 91.9°F (33.3°C) the rest of each year".
• reduce pH and flow monitoring to monthly from the current weekly requirement and delete
requirements for monitoring zinc and conducting annual pollutant analysis at outfall 002.
Please note that current data are used throughout the NPDES application whore available. In addition,
supplemental information is enclosed to reflect conditions for the station. This information is
representative of station operation for the period from July 1998 through June 1999.

requirements of North Carolina General. Statute 143-21.5.1 and the Memorandum of Agreement between
North Carolina and the ITS Environmental Protection Agency dated December 6, 1983.
In a Ietter dated ,rune 22, 1995 you requested various modifications to the subject draft permit.
Many of your requested changes were minor adjustments to wording,

The acute toxicity monitoring requirement erroneously mentioned in the draft pest cover letter
has not been included in the final permit. Based ou the additional data supplied by Mr. I eWi
monitoring requirements for cadmium and sulfates have been deleted from the Bffluent Limitations and
Monitoring Requirements for outfall 001. That same data reveal elevated levels of manganese at a
downstream monitoring location. We urideirstand that the source of this manganese may be the

Re: Request for North Carolina )DENR Certification under the IRS' Rapid Tax Amortization
Program for 1996 Additions at the Marshall Stearn Station
Dear Mr. Morris:
Pursuant to the regulations included in Part 20, Chapter 1, TitIe 40, Code of Federal Regulations
(40 CFR) and Section 1.169 of the income Tax Regulations, Part 1, Subchapter A, Chapter 1,
Title 26, Code of Federal Regulations, please find attached the completed copies of the United
States Environmental Protection Agency's (U.S. EPA's) EPA Form 3300-1, Application for
Certification of Pollution Control Facility, and accompanying attachments, covering 1996 ash
line system additions to Duke Energy Corporation's Marshall Steam Station, located in Terrell,
North Carolina, for tax purposes. North Carolina Department of Environmental & Natural
Resources' (DENR's) completion of the State Certification Form included within these
applications is required as a process step in the Internal Revenue Service's Rapid Tax
Amortization Program outlined under section 169 of the Internal Revenue Code.
The Marshall Steam Station system addition which is the subject of this application is the
Station's ash line. As the tax treatment under the IRS's Rapid Tax Amortization Program is
applicable to facilities which "remove, alter, dispose of, store, or prevent the creation of
pollutants, contaminants, wastes, or heat," and as the ash line is encompassed within this
definition, the facility addition meets the 40 CFR criteria for a pollution control facility.
The original application and accompanying attachments have been submitted to:
Mr. Robert F. McGhee
Director of Water Management Division
c/o Regional Administrator

C ' Duke P er V...-' '
Marshall Stearn Station
Catawba County
In accordance with your application for discharge permit received on December 28, 1994, we are
forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the US Environmental Protection Agency dated December 6, 1983.
In a letter dated June 22, 1995 you requested various modifications to the subject draft permit
Many of your requested changes were minor adjustments to wording, punctuation, etc. These changes
have been adopted as you requested. Other more significant concerns included the monitoring
requirements for acute toxicity, Manganese, Cadmium, Sulfates, and pH for outfall 001; the monitoring
frequency for Oil/Grease, Total Suspended Solids (TSS), Total Copper, Total Iron, Total Selenium, and
pH and the TSS daily maximum limit of 50.0 mg/1 for outfall 002, and the monitoring requirements for
outfall 003. These requests were subsequently discussed in a meeting between Ron Lewis of your office
and Dana Bolden and Farrell Keough of the Division's Water Quality Section.
The acute toxicity monitoring requirement erroneously mentioned in the `Ter
has not been included in the final permit. Based on the addition-, -
monitoring requirements for cadmium and sulfates have be'' -

The meeting between Mr. Lewis, Mr. Bolden, and Mr. Keough resulted in a clearer
understanding of the nature of the discharge from outfall 003. In particular, Mr. Lewis indicated that the
outfall 003 discharge is directly to the cooling water intake canal serviced by outfall 001 and that 'no
discharge would occur from outfall 003 unless the cooling water intake were in operation.. In light of
this information and peryour request, all monitoring requirements for outfall 003 have been deleted.
•
I hope these modifications satisfactorily address your concerns. If any parts, measurement
frequencies or sampling requirements contained in this permit are unacceptable to you,'you'have the
right to an adjuclicatory hearing upon written request within thirty (30) days following receipt of this
letter. This request must be in the form of a written petition, conforming to Chapter 150E of the North
Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer
27447, Raleigh, North Carolina 27611 -7447. Unless such demand is made, this decision shall, be final
and binding.
Please take notice this permit is not transferable. Part II, B.2: addresses the requirements to be
followed in case of change in ownership or control 'of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be required
by the Division of Environmental Management or permits required by the Division of Land Resources,
Coastal Area Management Act or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Dana Bolden at telephone
number 919/733-5083, extension 518.

Dear Mr. Morris:
Pursuant to the regulations included in Part 20, Chapter I, Title 40, Code of Federal Regulations

Title 26, Code of Federal Regulations; please find attached the completed copies of theUnited
States Environmental Protection Agency's (U.S. EPA's) EPA Form 3300-1, Application for
Certification of Pollution Control Facility, and accompanying attachments, covering 1997
aerated lagoon wastewater pre-treatment facility additions to Duke Energy Corporation's
Marshall Stearn Station, located in Terrell, North Carolina, for tax purposes. North Carolina
Department of Environmental & Natural Resources' (DENR's) completion of the State
Certification Form included within these applications is required as a process step in the Internal
Revenue Service's Rapid Tax Amortization Program outlined under section 169 of the Internal

Station's aerated lagoon pre-treatment wastewater facility. As the tax treatment under the IRS's
Rapid Tax Amortization Program is applicable to facilities which "remove,• alter, dispose of,
store, or prevent the creation of pollutants, contaminants, wastes, or heat," and as the pre-
treatment facility is encompassed within this definition, the facility addition meets the 40 CFR

- Permit fro, N'C e i , 4937
' Duke P}ery�
Marshall Steam Station
Catawba County --
In accordance with your application for discharge permit received on December 28, 1994, we are
forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143.215 ,1 and the Memorandum of Agreement between
North Carolina and the US Environmental Protection Agency dated December 6,1983.
In a letter dated June 22, 1995 you requested various modifications to the subject draft permit.
Many of your requested changes were minor adjustments to wording, punctuation, etc. These changes
have been adopted as you requested. Other more significant concerns included We monitoring
requirements for acute toxicity, Manganese, Cadmium, Sulfates, and pH for outfall 001; the monitoring
frequency for Oil/Grease, Total Suspended Solids (TSS), Total Copper, Total Iron, Total Selenium, and
pH and the TSS daily maximum limit of 50.0 mg/1 for outfall 002, and the monitoring requirements for
outfall 003. These requests were subsequently discussed in a meeting between Ron Lewis of your office
and Dana Bolden and Farrell Keough of the Division's Water Quality Section.
The acute toxicity monitoring requirement erroneously mentioned in the draft permit cover letter
has not been included in the final permit. Based on the additional data supplied by Mr. Lewis,
monitoring requirements for cadmium and sulfates have been deleted from the Effluent Limitations and
Monitoring Requirements for outfall 001. That sarn,e data reveal elevated levels of manganese at a
downstream monitoring location. We understand that the source of this manganese may be the
hypolimnetic water used for condenser cooling and discharged via outfall 001. The required monitoring
will aid in verifying the source of the elevated Manganese concentrations and enable Duke Power and
the Division to seek a long terra solution to the concerns associated with the manganese discharge.
Additionally, the pH monitoring frequency has been reduced to monthly to coincide with the manganese
monitoring frequency.
Upon evaluation of the available data, we were able to comply with your
reuest to reduce the
monitoring frequency for Oil/Grease, Total Suspended Solids (TSS), Total Copper, Total Iron, and Total,
Selenium from 2/month to monthly and the frequency for pH monitoring from daily to weekly.
Additionally, re-evaluation of the appropriate Federal guidelines for daily maximum Total Suspended
Solids discharge concentrations indicated that a 65.0 rag/1 Total Suspended Solids limitation is
appropriate for outfall 002. This modification has been incorporated into your permit. -

Mr. John S. Carter, Technical Systerns Manager
Page.
The meeting between Mr. Lewis, Mr. Bolden, and Mr. Keough resulted in a clearer
understanding of the nature of the discharge from•outfall 003. In particular, Mr. Lewis indicated that the
outfall 003 discharge is directly to the coolingswater intake canal serviced by cattail 001 and that no
discharge would occur from outfall 003 unless the cooling water intake were in operation. In light of
this information and peryour request, all monitoring requirements for outfali 003 have been deleted.
I hope these modifications satisfactorily address your concerns. If any parts, measurement
frequencies or sampling requirements contained in this permit are unacceptable to you,'.you'have the
right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this
letter. This request must be in the form of a written petition, conforming to Chapter 150)3 of the North
Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer
27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, This decision shall be final
and binding.
PIaaaa take notice this permit is not transferable, Part II, 8.2. addresses the requirements to be
followed in case of change in ownership or control bf this discharge.
This permit does not affect the legal requirements to obtain other permits which may be required
by the Division of Environmental Management or permits requited by the Division of Land ll.esoutces,
Coastal Area Management Act or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Dana Bolden at telephone

2. Type of Profi ose:? *Treatme ;t Facility: The applicant proposes
to construct an aerated lagoon as the method of pretreatment
prior to discharging to the ash basin. The package plant is
being replaced due to its proximity to Lake Norman (<50
feet) and its collection system limits site expansion.

PART Xfl - EVALUATION AND RECOMMENDATIONS
The perm ttee, Duke Power Company (DPC) requests approval to
construct an aerated lagoon (as pretreatment for the domestic
wastewater generated at• DP,'s Marshall steam Station) as well as
assorted pumps, piping and other appurtenances necessary to
upgrade the existing wastewater collection system. The existing
WWT facility has, in years past, experienced overflows from both
the collection system and the WWTP as a result of excessive
rainfall. Although repairs have been made to the WWTP (and
collection system) to minimize the potential for future
overflows, its close proximity to surface waters and it location
on the Marshall plant site (the treatment plant location
restricts a planned steam plant expansion project) made it
possible for DPC to justify relocating the WWTP. .
Fending a technical review and approval by n&.E, ; +
