1.0 Introduction
Duke Energy Carolinas(DEC) owns and operates the Rogers Energy Complex located on the Broad River
in Cleveland & Rutherford County, Mooresboro, North Carolina.The Rogers Energy Complex National
Pollutant Discharge Elimination System (NPDES) Permit (No. NC0005088, Section A.14.) requires DEC to
conduct trace elements monitoring in fish muscle tissue each calendar year, in accordance with a study
plan approved by the North Carolina Department of Environmental Quality(NCDEQ).This study plan
outlines the proposed methods for sampling, analyzing, and data reporting to fulfill these NPDES permit
monitoring requirements. DEC 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 Sampling Areas
Target fish will be collected from two locations on the Broad River(see attached map)for trace element
analysis of muscle tissue.The UP location will serve as a reference to monitor background trace element
concentrations in fish muscle tissue upstream of the Rogers Energy Complex ash basin discharge. All UP
samples will be collected on the Broad River upstream of the UP location depicted on the attached map
(approximately 2.5 kilometers, or greater, upstream of the current ash basin discharge). Exact collection
locations will be dependent upon river flow and access at the time of sampling. The DN location will
serve to monitor uptake of elements in fish muscle tissue downstream of the Rogers Energy Complex
ash basin discharge. All DN samples will be collected on the Broad River at the DN location depicted on
the attached map (approximately 10 kilometers, or less, downstream of the current ash basin
discharge). Exact collection locations will be dependent upon river flow and access at the time of
sampling. The sampling areas are similar to those previously approved for the Rogers Energy Complex
by NCDEQ(Duke Energy 2013).
3.0 Target Fish Species for Tissue Monitoring
The proposed target species are based on availability, recreational importance as a game or food fish,
and general trophic level. Duke Energy personnel will attempt to collect six individuals of insectivorous
(e.g., sunfish) and piscivorous (e.g., black bass) species. 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(USEPA), 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 (USEPA 2000). Conformance with this guideline will depend
upon the fish/size class availability at a particular location.
4.0 Field Sampling Methods
Standard fishery sampling methods, including active and passive gear types, will be employed to collect
target species. Boat electrofishing (Procedure FSH-250.0, Rev. 5),trap nets (Procedure FSH-257.00, Rev.
2

3), or other standard fishery sampling gear types will be used as necessary to obtain the required
samples. If used, nets will be checked and captured fish removed daily during the sampling period.
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 placed in a labeled (sample date, sample location,
facility, etc.) bag on ice.This information will be recorded on field fisheries data sheets(generally
electronic). Each day the sealed bags of collected fish will be frozen in deep freezers. 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.
Supporting information will be collected during each trip including temperature, dissolved oxygen,
specific conductivity, and pH from the surface of each sampling location. Other environmental
conditions may be recorded during each sampling period such as weather conditions and lake level as
appropriate.
5.0 Tissue Analyses
All fish will be processed in the laboratory for metals analysis according to Procedure NR-00107 Rev.4
Trace Element Monitoring Laboratory Procedure (approved SOP on file with NCDEQ). Sample custody
and tracking of samples will be performed using chain-of-custody forms during transport to or from the
laboratory. Quality of vendor laboratory data, if applicable, will be ensured through the use of National
Institute of Standards and Technology(NIST)tissue standards.The remaining processed sample will be
archived for two years if re-analysis is needed.
6.0 Data Analysis and Reporting
Arsenic, mercury, and selenium concentrations (converted to µg/g fresh weight) determined from the
fish tissue analyses will be reported.A report with the sampling methods, data analysis, and conclusions
will be prepared and submitted with the subsequent NPDES permit renewal application as required by
NPDES Permit No. NC0005088.
