1.0 Introduction
Duke Energy Progress (DEP) owns and operates the Asheville Steam Station (Asheville Station)
located on the east side of the French Broad River in Buncombe County, Arden, North Carolina. As
required by the Asheville Station's National Pollutant Discharge Elimination System (NPDES) Permit
No. NC0000396 (current prior to December 1, 2019), Special Condition A. (13). monitoring of
mercury and selenium in fish from the French Broad River began after Flue Gas Desulfurization
(FGD) operations commenced in December of' 2005. Sampling was conducted according to the
previously approved monitoring plan. This data report is submitted to fulfill the annual monitoring as
required by the above NPDES permit.
2.0 Study Site Description and Sampling Locations
Fish were collected from three locations of the French Broad River (figure 1). These locations
were adjacent to the Asheville Station discharge (Station DI), 6.2 kilometers upstream of the
discharge (Station UP) and 10.8 kilometers downstream of the discharge (Station DN).
3.0 Target Species
The target fish were black bass (preferred SmallmOuth Bass), sunfish (preferred Redbreast
Sunfish) and suckers (preferred Black Redhorse). Where the frill complement of preferred target
species were not available, Largernouth Bass, Rock Bass, Spotted Bass, Bluegill, and Golden
Redhorse were substituted as necessary (Table 1). As recommended by the U.S. Environmental
Protection Agency (USEPA) an attempt was made to limit the smallest fish to 75% of the largest
fish total length by species depending on availability (USEPA 2000).
4.0 lField Sampling Methods
Fish were collected using electrolishing procedures specified in the DEP Biology Program
Procedures Manual (Procedure NR-00080, Rev. 2 and NR-00095, Rev. 1) which is approved by
the North Carolina Department of Environmental Quality under the DEP Biological Laboratory
Certification (# 006). Only live fish that showed little or no signs of deterioration were retained
for analysis and put in a labeled (date, station, etc.) bag and placed on ice until frozen. Ancillary
fisheries data including species, number, total length (mm), and total weight (g) were also
recorded. Each day collected fish were transferred to a freezer on -site and maintained in the
frozen state until processing at the DEP New Hill Trace Element Laboratory. Associated water

quality data including water temperature, dissolved oxygen, and specific conductance were
recorded daily at the surface at each sampling location.
5.0 Laboratory Processing and Mercury and Selenium Analysis
All fish samples were processed in the trace element laboratory according to procedure NR-
00107, Rev. 4 Trace Element Monitoring Laboratory Procedure. Aliquots of the processed
samples (lyophilized left axial muscle; right muscle occasionally included when needed) were
sent to Pace Analytical for analysis (EPA 7374 — 1-Ig,. EPA 6020 — Se). Quality control was
achieved utilizing analytical standards, replicates, and certified reference materials. following
analysis, the, processed samples were archived and will be kept at least two years in the event
that re -analysis is needed.
6.0 Data Analysis and Reporting
Mercury and selenium concentrations (converted to µg/g wet weight) in the fish muscle tissue
collected during 2018 are shown in Table l . In addition to the length and weight of each fish, the
dry -to -wet weight ratios are presented to convert the mercury and selenium concentrations wet
weight values back to dry weight values as desired. The 2004 baseline data are presented as well
for comparison purposes (Table 2). During 2018, 67 of the 88 fish collected at all three sample
locations were below the North Carolina Health Directors Mercury Action Advisory Level of 0.4
µg/g wet weight (NCDHHS 2006). At location UP, one Golden Redhorse, two Redbreast
Sunfish, two Largemouth Bass, two Rock Bass, and two Smallmouth Bass had mercury
concentrations in axial muscle (edible flesh) equivalent to or greater than the advisory level
(highlighted in Table 1). Eight Golden Redhorse and one Smallmouth Bass at location DI had
mercury tissue concentrations above the advisory level while one Redbreast Sunfish and one
Smallmouth Bass at location DN were above the level (also highlighted in Table 1). Based on the
mercury concentrations in fish at all three locations, the bioaccumulation pattern appears to be
random with no apparent contribution of mercury in fish tissues attributable to the Asheville
Station discharge to the French Broad River. During 2018, all fish collected at the three locations
were below the North Carolina human consumption advisory level of 10 µg/g (wet weight) for
selenium, however, two fish (highlighted in `Fable 1) of 27 fish collected at location DI were
slightly above the USEPA screening value of 2.457 µglg (wet weight) for subsistence fishermen
(USIaPA 2000).
