Proposed NPDES Fish Tissue and Ambient Sampling Plan
Dear Ms. Karoly:
Enclosed is Duke Energy Progress LLC's (Duke Energy's) NPDES Sampling Plan. This plan has been
prepared and is being submitted in accordance with condition A(17) and A22) of NPDES permit
NC0001422 for the L.V. Sutton Energy Complex.
Duke Energy appreciates your review of this study proposal. As required by the permit, upon approval by
the Division, the study plan will become an enforceable part of the NPDES permit.
If there are any questions, please contact either:
• Mr. R. Glenn Rivenbark, NPDES ORC for the L. V. Sutton Energy Complex; phone (910) 341-
4774, e-mail [e-mail];

NPDES Water Quality and Fish Tissue Monitoring Plan
March 2016
Sutton Energy Complex
NPDES No. NC0001422
<4 RELY

1.0 Introduction
Duke Energy Progress,LLC (DEP) owns and operates the L.V. Sutton Energy Complex (Sutton Plant)
located near Wilmington, North Carolina. The National Pollutant Discharge Elimination System
(NPDES) permit for the Sutton Plant requires DEP to conduct trace elements monitoring in fish muscle
tissue once per year, in accordance with a study plan approved by the North Carolina Division of
Environmental Quality (NCDEQ). This study plan outlines the proposed methods for sampling,
analyzing, and data reporting to fulfill the NPDES permit requirement for fish tissue and ambient metals
monitoring. DEP recognizes that the specifics of this plan may need to be modified to reflect information
gained during implementation. Any such modifications shall be subject to NCDEQ approval.
2.0 Fish Tissue Monitoring Plan Near Outfalls 001, 002 and 004
Fish muscle tissue will be collected from locations on the Cape Fear River and in Sutton Lake.
2.1 Target Species
The proposed target species will be selected based on prior sampling experience, likely availability,
importance as fish food, predatory nature of certain species, and general trophic level. Species may
include Micropterus spp. (top predator), and Lepomis spp. (intermediate predator), however other similar
species may be retained if the primary target species are unavailable.
Specimens retained for analysis will be individuals considered of sufficient size for human consumption.
As recommended by the US Environmental Protection Agency (EPA), an attempt will be made to ensure
that the size of the smallest individual sampled will not be less than 75% of the total length of the largest
fish within each species group (US EPA 2000). Conformance with this guideline will depend upon the
availability of size class at a particular sampling station.
2.2 Field Sampling Methods
The following active and passive sampling methods may be employed to efficiently collect target species:
boat electrofisher(pulsed DC current), hoop nets, gill nets, and trotlines. Standard sampling methods will
be used for each gear type as outlined in the American Fisheries Techniques Manual (Zale, Parrish, and
Sutton 2012).
Fish retained for trace elements analysis will be identified to species, measured for total length to the
nearest millimeter, weighed to the nearest gram, and immediately placed in a labeled (date, transect,
station, etc.) zip-lock bag on ice until they can be frozen. Only fresh fish that show no signs of
deterioration will be retained for analysis. Fish that have visible, open wounds that could allow
contamination will not be retained.
2.3 Laboratory Processing and Elements Analysis
All fish will be processed in the laboratory for arsenic, selenium and mercury analysis. Sample custody
and tracking of samples will be performed using chain-of-custody forms during transport to or from the
laboratory. The remaining sample will be archived and kept by DEP for up to two years in the event that
re-analysis is needed.
2.4 Data Analysis and Reporting
A report with the sampling methods and data analysis will be prepared and submitted upon the
subsequent NPDES permit renewal application as required by the current NPDES permit NC0001422.

3.0 Instream Monitoring in Cape Fear River and Sutton Lake
In accordance with the NPDES permit, DEP will collect ambient samples at three locations: two in the
Cape Fear River(an upstream sample at CFUP and a downstream sample at CFDN) and one on Sutton
Lake at approximately location 8B. The locations have been selected to meet the NPDES permit
requirement: 1000 ft upstream and downstream from outfall 001 and 1000 ft from outfall 004. The
locations are noted in Figure 1. The samples will be collected twice per year and will include total
arsenic, total selenium, total mercury (method 1631),total chromium, total lead, total cadmium, total
copper and total zinc. The monitoring results will be submitted with the NPDES renewal application.
Currently, DEP is an active member of the Lower Cape Fear River Program. As described by the NPDES
permit, the instream monitoring requirements are provisionally waived in light of DEP's participation in
the program. Monitoring requirements will be reinstated if DEP ends its participation with the
Monitoring Coalition'.
