L.V. Sutton Energy Complex 2022 Permit Renewal Application
Attachment 4
Form 2C —Section 3 Flow, Sources of Pollution, and Treatment Technologies
The L. V. Sutton Electric Plant has two simple-cycle Internal Combustion (IC)turbine units and a natural
gas-fired 2x1 Combined Cycle(CC)combustion turbine. The plant has a 1,110-acre(6,900 acre-ft)
wastewater cooling pond on the east side of the Cape Fear River approximately ten river miles upstream
of Wilmington, North Carolina. Water is withdrawn from the Cape Fear River,as required,to makeup
evaporative and blowdown losses from the cooling pond.
Chemical constituents contained in the discharge from the permitted outfall will, in part, be representative
of the naturally-occurring chemical quality and quantity of the intake water and will also have chemical
constituents of such quality associated with similar discharges for generating facilities of this size,type,
and in this geographical location. Either all or part of the elements in the Periodic Table, either singularly
or in any combination, may from time to time be contained in the discharge.
The Sutton Plant had one external permitted outfall to the Cape Fear River. This outfall was a discharge
from the cooling pond (Outfall 001) which received all combined wastewaters from the plant(including
several internal outfalls).
In 2015, Duke Energy provided an updated permit application, upon request of the Division of Water
Resources,to support the characterization of the Cooling Pond as Waters of the State. Based on that
classification,the site now has the following external outfalls:
• Outfall 001 can discharge through the sluice gates to the Cape Fear River. Discharges to alter
the level water in Sutton Lake would not be regulated under the NPDES Permit.
• Outfall 008 is located at a compliance point at the end of the effluent channel into the Cooling
Pond.
The waste streams contributing to these outfalls are described in further detail below.
Historic Cooling Pond Discharge
Historically Sutton Plant's discharge of recirculated cooling water from the Cooling Pond to the Cape Fear
River was considered a regulated NPDES outfall. However,due to NCDEQ's reclassification of the
cooling pond,only outfall 008 is directed to the cooling pond. Under current site operations,the cooling
pond is not expected to discharge except for maintenance purposes or in anticipation of an extreme
weather event,such as a hurricane, when additional freeboard is needed to prevent overtopping of the
pond dikes. These discharges to alter the level of water in the cooling pond would not be regulated under
the NPDES permit.
Outfall 001
Effluent is directed to the Cape Fear River(to Outfall 001). Historic practice was to route a
minimum of 4.0 MGD to the cooling pond before additional effluent routed to the Cape Fear River.
This outfall consists of ash pond discharge, groundwater, landfill leachate, and stormwater runoff.
Additionally,this outfall may include cooling water from Outfall 008
Outfall 008- Effluent Channel
Recirculated Condenser Cooling Water
A4-1

Duke Energy Progress, Inc. NPDES Permit NC0001422
L.V.Sutton Energy Complex 2022 Permit Renewal Application
The condenser cooling water for the CC block is withdrawn from and discharged to the cooling
pond.The heated discharge is routed around baffle dikes within the cooling pond to achieve
maximum surface cooling efficiency and before being recirculated through the condenser cooling
water intake structure. Evaporation, which is estimated to consume approximately 1.5 MGD
above natural evaporation rates during times of full operation, effectively cools the heated water
discharge. Biological fouling control agents are used on heat exchanger surfaces.
Non-contact Cooling Water
Non-contact cooling water is also withdrawn from and returned to the cooling pond. This water
provides indirect cooling for various equipment by absorbing heat as it passes through a heat
exchanger. No direct contact is made with any other equipment or process.
Stormwater
There are several discrete stormwater conveyances to the effluent channel including three
discharges from stormwater basins (the South Wet Detention Basin, the North infiltration Basin,
and the West Retention Basin). Internal stormwater outfalls SW001, SW002, SW003, SW004,
SW005, SW006, and SW007 drain to the Effluent Channel (Outfall).
During certain extreme storm events(e.g., 25-year, 24-hour),storm water may inundate areas
around the plant site and accumulate beyond design capacity. Storm water collected during
these conditions may be pumped directly to the cooling pond or to the surrounding landscape.
Other Site Wastewaters
During maintenance activities, sludge removed from basins, sumps, etc.will be transported off-
site for proper disposal.
Other Site Wastes
Domestic Wastes
Sanitary wastes are treated by an onsite septic tank and drainage field that is permitted by the
New Hanover County Health Department. The septage is exempt from the 40 CFR 503
standards. Duke Energy Progress, Inc. will submit appropriate information to the EPA if
required.Wash/rinse wastewater from an on-site washing machine is also routed to the septic
system.
Low-Volume Wastes
All waste streams not identified above are categorized as low-volume wastes.These wastes
include plant drains, which convey miscellaneous equipment leakage, equipment drainage for
maintenance, equipment washdown water, sampling streams,service water system blowdown,
and water treatment wastes. Any of the chemical additives disclosed in Attachment 4 may be
present in Low Volume Wastes.
Fire Water System
Several plant heat exchangers are cooled by the fire water system. Fire water is withdrawn from
the cooling pond.
Intake Screen Backwash
The combined cycle power block has an intake structure with an automatic intake screen
backwash system.

Inactive Hazardous Waste Sites List Areas
A former ash disposal area and the old ash pond were listed on the State's Inactive Hazardous
Waste Sites List.
Pesticide Usage in Sutton Cooling Pond
Herbicides are used when needed to control nuisance aquatic vegetation. These herbicides are
applied by licensed applicators, or persons under the immediate supervision of a licensed
applicator, in accordance with the manufacturer's instructions. Pesticides are used when needed
to perform biological assessments of fish populations. These pesticides are applied by licensed
applicators, or persons under the immediate supervision of a licensed applicator, in accordance
with the manufacturer's instructions.
Outfall 010—North Pond Emergency Spillway
With the completion of ash pond excavation in 2020 and the closure of the on-site lined ash
landfill, the outfall was created. Discharge only occurs with storm events that exceed the 25-year
24-hour storm event classification.
Outfall 011 —South Pond Emergency Spillway
With the completion of ash pond excavation in 2020and the closure of the on-site lined ash
landfill, the outfall was created. Discharge only occurs with storm events that exceed the 25-year
24-hour storm event classification.

1.0 Introduction
Duke Energyowns and operates the L.V.Sutton EnergyComplex(Sutton)located to the Cape
P P adjacent
Fear River near Wilmington in New Hanover County, North Carolina. The Sutton National Pollutant
Discharge Elimination System(NPDES)Permit(No.NC0001422 Section A.19)requires monitoring of
trace elements (arsenic, selenium, and mercury) in fish tissues within Sutton Lake and the Cape Fear
River annually (Figure 1). Fish were collected according to the study plan submitted to the NCDEQ-
DWR and mentioned in the NDPES permit(dated October 1,2017)and the resulting data are submitted
in this report(Duke 2018).
2.0 Study Site Description and Sampling Locations
Target species were collected from within Sutton Lake and the Cape Fear River. In Sutton Lake,
the water is continuously or near continuously circulating, and is considered mixed and
homogeneous,as a result,target species were collected from the whole lake as available. From the
Cape Fear River, fish were collected in three areas (i.e., UP, DI, and DW; Figure 1). Area UP is
located approximately between 1.1 and 2.8 miles upstream of the plant discharge and served as a
reference location to monitor background trace element concentrations in fish muscle tissue. The
area in the immediate vicinity of the plant discharge point (DI) served to monitor potential near-
field uptake of elements in fish muscle tissue. Area DW,between approximately 2.1 and 2.6 miles
downstream of the plant discharge point, served to monitor far-field uptake of elements in fish
muscle tissue.

and Sutton Lake.
3.0 Target Species
The target species of fish for tissue analysis from both the lake and river were Micropterus spp.
(i.e.,Largemouth Bass)and Lepomis spp.(i.e.,Bluegill,Hybrid Sunfish,Redbreast Sunfish,Redear
Sunfish,or Warmouth). The study plan called for six individuals per species group to be collected
annually within each sample location resulting in a total of 48 fish from the lake and 144 fish from
the river. As recommended by the US Environmental Protection Agency(US EPA)for whole body
2

assessments, an attempt was made to limit the smallest fish to 75% of the largest fish total length
p g g
by species depending on availability (US EPA 2000).
4.0 Field Sampling Methods
Fish were collected using approved procedures (Procedure ESFP-SW-0600-Trace Elements Field
Procedure-Rev.0 applies to fish collected after 2020 and NR-0095-Trace Element Field Procedure-
Rev. 1 applies to fish collected prior to 2020) under Duke Energy's North Carolina Biological
Laboratory Certification # 006 located at New Hill, NC. Only live fish that showed little or no
signs of deterioration were retained for analysis. Retained fish were identified to species,measured
for total length (mm), weighed (g), individually tagged (Floy tags), bagged by species/site, and
placed on ice and transferred to a freezer within 24 hours of collection following ESFP-SW-0600-
Trace Elements Field Procedure-Rev. 0 (applies to fish collected after 2020) or NR-0095-Trace
Elements Field Procedure-Rev. 1 (applies to fish collected prior to 2020).
5.0 Laboratory Processing and Arsenic,Selenium and Mercury Analysis
All fish samples were processed in the New Hill Trace Element Laboratory according to procedure
ESFP-SW-0601-Trace Elements Sample Preparation-Rev. 0 (applies to samples processed after
2020) or NR-00107-Trace Element Monitoring Laboratory Procedure-Rev. 4 (applies to samples
processed prior to 2020). The processed samples (lyophilized left axial muscle; right muscle
occasionally included when needed) were analyzed for arsenic, selenium, and mercury by x-ray
spectrophotometry in accordance with procedure ESFP-SW-0602-Trace Elements Analysis
Procedure-Rev. 0 (applies to samples processed after 2020) or NR-00107-Trace Element
Monitoring Laboratory Procedure-Rev. 4 (applies to samples processed prior to 2020). Fish
collected during 2018 were analyzed by Pace Analytical in the Green Bay, Wisconsin lab (As and
Se were analyzed in accordance with EPA 6020 and Hg was analyzed in accordance with EPA
7374). Quality control was achieved by use of replicates and certified reference materials (i.e.,
NIST tissue standards). The remaining sample materials were archived and kept for at least two
years in the event that re-analysis was needed.
6.0 Data Analysis and Reporting
In total, 28 Micropterus spp. and 28 Lepomis spp. were collected and analyzed for trace elements
within Sutton Lake, and 69 Micropterus spp. and 71 Lepomis spp. were collected and analyzed for
3

trace elements from the three locations on the Cape Fear River (Table 1). Fish species and sizes
ranged with annual availability (Appendix A).

At least six individuals per species group were collected from both the river sites and Sutton Lake,
except for fish collected from the Cape Fear River during 2018. Flood waters from Hurricane
Florence inundated the Cape Fear River with anoxic waters causing fish kills throughout the lower
river (NCWRC 2018). Despite multiple attempts to collect trace element fish from the Cape Fear
River during 2018,only a few fish were collected(i.e.,one from UP and three from DW;Appendix
A). Arsenic, selenium, and mercury concentrations (converted to µg/g wet weight) in the fish
muscle tissue collected from 2018 to 2021 are shown in Table 2.

I When concentrations were less than the detection limit,then half the detection limit value was used for statistical analysis.
2 Detection limits varied with year due to the use of multiple labs to process samples during the permit cycle.
In addition to the length and weight of each fish, the dry-to-wet weight ratios are presented to
convert the arsenic, mercury, and selenium concentrations wet weight values back to dry weight
values as desired(Appendix A). The arsenic, mercury, and selenium concentrations in fish tissues
were very low and showed no indication of bioaccumulation from legacy coal operations of Sutton.
In addition, all fish collected from 2018 through 2021 were well below the US EPA wet weight
Screening Values for Recreational Fishermen of 1.2 µg/g for arsenic,20 µg/g for selenium,and 0.4
µg/g for mercury (US EPA 2000;Table 2).
