EXECUTIVE SUMMARY
Sportfish and bottom feeding species were collected in 1999 from six locations in the Pigeon
River and analyzed for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 2,3,7,8-
tetrachlorodibenzofuran (TCDF) and other CDD and CDF isomers. TCDD and TCDF
residues were not detected in any of the 10 sportfish fillet composites collected downstream of
the Blue Ridge Paper Canton mill. Sportfish used were redbreast sunfish, rock bass, black
crappie, largemouth bass, and smallmouth bass. TCDD and TCDF concentrations in fillet
composites from bottom feeders were very low (range=non-detected to 1.1 ppt) at the three
riverine locations downstream of the mill. Bottom feeders used at these locations were
common carp and smallmouth buffalo. TCDD concentrations in bottom feeder fillet
composites at the two Waterville Lake locations were 0.58 ppt and 4.7 ppt (Stations 4A and
4B, respectively) for carp, and 0.83 for channel catfish at Station 4A and non-detect for
flathead catfish at Station 4B. Since 1990, TCDD concentrations in common carp fillets have
declined dramatically (86-99 percent) at all downstream stations (Figure.F,S-1).

1. INTRODUCTION
This report details the results of a study conducted during 1999 to determine the concentrations
of 2,3,7,8,-TCDD (dioxin) and 2,3,7,8-TCDF (furan) in fish collected from the Pigeon River
' near Canton, North Carolina. The study described herein is number 10 in a series of fish
tissue surveys designed and conducted to be completely responsive to the requirements of Part
III, Special Conditions Section (paragraph H) in Blue Ridge Paper's current NPDES permit for
the Canton Mill (Permit No. NC0000272). Sampling locations, selection of target species,
sampling methods, and sample preparation/preservation techniques are in accordance with
study plan details submitted to U.S. EPA Region IV during February 1990 (EA 1990). The
approved study methods and scope detailed herein follow those reported in the 1990, 1991,
1992 and 1993 Pigeon River dioxin study documents prepared by EA Engineering, Science,
and Technology (EA 1991, 1992, 1993a and 1993b). The 1994-1999 (EA 1994, 1995, 1996,
1997, 1998, and the present study) fish tissue surveys maintained the basic study framework of
the previous years; however, selected project details were modified to-be responsive to the
suggestions/recommendations of the North Carolina Department of Environment, Health, and
Natural Resources, the Tennessee Wildlife Resources Agency, and U.S. EPA Region IV.
The 1999 study was conducted during 6-11 August, during which time biologists from EA
collected and prepared fish tissue samples from six sampling locations on the Pigeon River.
Details relevant to the location of Pigeon River sampling stations and fish tissue sampling
objectives follow in Sections 2 and 3, respectively. Fish collection techniques and level of
effort are detailed in Section 4; methods of sample preparation and shipment are presented in
Section 5. Analytical results are summarized in Section 6 and references are provided in
Section 7.

2. SAMPLING LOCATIONS
' In accordance with the study plan submitted to U.S. EPA Region IV (EA 1990), fish were
_f collected from five locations on the Pigeon River. Four monitoring stations were located
downstream from the Canton Mill outfall, and one control or background site was located
' upstream of it. In response to a special request from U.S. EPA Region IV, an additional
downstream monitoring station was established is Tennessee in 1992. Thus since 1992, six
locations have been sampled. Detailed sampling station information is provided in Table 2-1 and
Figure 2-1.
it
Station 1, the background site, is located at Pigeon River Mile(RM) 64.5, approximately 1.2 RM
upstream from the Canton Mill outfall (Figures 2-1 and 2-2). Fish were collected from the river
reach adjacent to the Canton Recreational Park(located upstream from the city of Canton).
Except under extremely high flows, the Canton Mill dam blocks the movement of fishes and
thereby prevents the interaction of control and downstream monitoring station fishes. Monitoring
Station 2 is located upstream from Clyde, North Carolina at RM 59.0, approximately 4.3 RM
downstream from the Canton Mill outfall (Figures 2-1 and 2-3). Station 3 is 11.0 RM
downstream from the outfall (RM 52.3), in the vicinity of the old Rt. 209 bridge (Figures 2-1 and
24). Monitoring stations 4A and 4B are located in Waterville Lake at RM 41.5 and 39.0,
respectively (Figure 2-1). Station 4A is located approximately 21.8 RM downstream from the
Mill outfall, near the Messer Branch-Pigeon River confluence (Figure 2-5). Monitoring Station
4B is in the vicinity of the Wilkins Creek-Pigeon River confluence, approximately 24.3 RM
downstream from the Canton Mill outfall (Figure 2-6). Station 5 is located near Bluftlon,
Tennessee at RM 19.0, approximately 44.3 RM downstream from the Mill outfall and about 6
miles downstream of the CP&L Hydro site(Figure 2-7). Sampling stations were separated by at
least 5.5 RM(with the exception of the Waterville Lake stations which are only 2.5 RM apart).
All appropriate habitats were sampled within each study reach in an effort to collect the desired
complement of fishes. Brief site/habitat descriptions are provided in Table 2-1.
Fish sampling was conducted in the vicinity of each location described above, however, the
distance sampled at each station depended on how difficult it was to collect fish at that station.
At Station 1, an approximate 0.3 RM reach was sampled which extended from the (downstream
most)River Road (Rt. 215)bridge to the canoe launch area by the city park. The Station 2
sample reach was approximately 0.3 RM in length and was adjacent to a sharp bend along Old
Thickety Road. The Station 3 sample reach extended approximately 0.3 RM, near the old Rt. 209
bridge. At Station 4A, an approximate 0.4 RM reach of Waterville Lake was sampled adjacent to
and upstream from the Messer Branch-Pigeon River confluence. The Station 4B study area
consisted of a 1.0 RM reach of Waterville Lake located near the Wilkins Creek-Pigeon River
confluence. Sampling at Stations 4A and 4B included gillnetting near the shore along both the left
and right banks of Waterville Lake. At Station 5, an approximate 0.1 RM reach was sampled in
the vicinity of the I-40 Bridge.

3. SAMPLING OBJECTIVES
In accordance with the study plan (EA 1990), the goal of the fish collection effort was to
collect four composite samples at each of the six sampling stations identified in Section 2.
Station-specific objectives included the collection and preparation of one sample composed of
fillet sections from approximately five individual specimens of a representative bottom feeding
species. A second sample was composed of approximately five specimens of a bottom feeder
species for whole-body analysis. According to the study plan, each of the remaining two
composites should contain fillet sections from approximately five specimens of representative
sport fish species.
Common carp (Cyprinus carpio), white sucker (Catostomus commersont), and catfish species
(Ameiurus spp. or Ictalurus spp.) are the preferred bottom feeders; while northern hog sucker
(Hypemeliwn nigricans), black redhorse (Moxostoma duquesnet), and smallmouth buffalo
(Ictiobus bubalus) are identified as appropriate backup bottom feeding-species.(EA 1990).
Largemouth bass (Micropterus sahnoldes), rock bass (Ambloplites rupestris), and redbreast
sunfish (Lepomis auritus) are the recommended target sportfish species; and smallmouth bass
(Micropterus dolomieu), green sunfish (Lepomis cyanellus), brown trout (Salmo trutta), and
bluegill (Lepomis macrochirus) are the recommended alternative target sportfishes. Because of
their importance to the fishery, black crappie is one of the preferred sportfish species for
Waterville Lake. Beginning in 1997, a catfish fillet composite has been collected at each of
the two Waterville Lake stations. The catfish fillet composite is in addition to the standard
suite of composites at each Waterville Lake station. If the desired number of species can not
be collected at a station, the onsite fisheries scientist is to exercise best professional judgment
to obtain the best possible sample (EA 1990).
U.S. EPA Region IV (Cunningham 1990) recommended that the smallest specimen in each
composite should be equal to or greater than 75 percent of the total length of the largest
specimen in that composite. Every reasonable effort was made to collect the desired size,
species, and/or number of fish, however, the outcome of the sampling effort is dependent on
physical river conditions and the natural diversity and abundance of target fishes at each
sampling location. The 1999 Pigeon River collections yielded the desired complement of
species at each sampling station. The number of specimens collected made it possible to
composite individuals of similar weight and length (with larger/adult specimens preferred), and
the 75 percent rule was met for all samples, except for the fillet composite of five flathead
catfish at Station 4B in Waterville Lake (73 percent) and the fillet composite of five
smallmouth bass at Station 5 (69 percent).

4. FISH COLLECTION TECHNIQUES AND LEVEL OF EFFORT
Sampling was conducted from 6 August through 11 August 1999. Notes were recorded at
each sampling station with regard to the type of sampling gear, level of effort (time), and
habitat (Table 4-1). Surface temperature measurements at each location are summarized
below:
Station RM Date Temp m
1 64.5 8/9 23.3
i
2 59.0 8/9-10 30.3
3 52.3 8/8 26.0
4A 41.5 8/6-7 26.9
4B 39.0 8/6-8 26.2
5 19.0 8/11 22.3
Temperature was measured with a YSI temperature/dissolved oxygen meter. All fish
submitted for tissue analysis were measured to the nearest millimeter (total length) and
weighed to the nearest gram (wet weight). These data are summarized in Table 4-2.
The field investigators were equipped with an array of collecting gear which enabled sampling
of all habitats regardless of river conditions. U.S. EPA recommends active methods of fish
collection in their Sampling Guidance Manual (Versar 1984), such as electrofishing, trawling,
angling, or seining. These methods are preferred over passive methods (e.g., gill nets, trap
nets, trotlines) because the collection period is typically shorter (i.e., hours versus days--
thereby minimizing decomposition), and because samples are collected from more definable
areas (Versar 1984). Electrofishing was used at all stations, except 4A and 4B (Waterville
i Lake), where gill nets were necessary because of water depth. A boat electrofishing unit
(pulsed direct current) was used to sample fish at Stations 2, 3, and 5. The boat electrofisher
was equipped with a Smith Root Type VI electrofisher, powered by a 240-volt, 5000W
generator. A pram electrofisher, equipped with a Coffelt VVP-2C pulser and powered by a
120-volt, 1800W generator, was utilized at Stations 1 and 2. Thus, Stations 2 was sampled
by both pram and boat electrofishing techniques. Electrofishing techniques followed those
described in the National Dioxin Study (Versar 1984).
Fish collection techniques and level of effort (time) expended at each of the six stations are
summarized in Table 4-1. Total study effort involved ~6 electrofishing-hours and —374

net-hours. Total electrofishing duration (energized time) was 130, 117, 60, and 50 minutes at
Stations 1, 2, 3, and 5, respectively. Redbreast sunfish, rock bass, and/or largemouth bass
(the recommended target sport fish species) were used for at least one sport fish composite at
all stations, except Location 4A (Table 4-2). Black crappie were retained as an alternative
sport fish species at Waterville Lake Stations 4A (both sport fish composites) and 4B (1 of the
2 sport fish composites. Smallmouth bass was used as an alternative sport fish species at
Station 5 for 1 of the 2 sport fish composites. All specimens submitted for analysis appeared
healthy and in good condition. Lengths and weights for each fish making up each composite
are provided in Table 4-2.
Common carp, the recommended target bottom feeder, were collected (and prepared for fillet
and whole body analysis) at Stations 2 through 4B. No common carp were observed at
Stations 1 or 5. Alternative bottom feeding species were collected from Stations 1 (black
redhorse fillets and northern hog sucker whole body composites) and 5 (smallmouth buffalo
fillets and northern hog sucker whole body composites) for analysis. _The.physiography of the
Waterville Lake Stations 4A and 4B necessitated the use of gill nets for the collection of
bottom feeding species. All nets were pulled and examined on a regular basis to reduce stress
or specimen mortality. All fish that were used for tissue analysis were in good condition.
Sport fish (fillet) samples consisted of one composite of five redbreast sunfish and one
composite of five rock bass at Station 1; two composites of five redbreast sunfish at Stations 2
and 3; two composites of five black crappie at Station 4A; one composite of five black crappie
and one composite of five largemouth bass at Station 413; and one composite of five rock bass
and one composite of five smallmouth bass at Station 5 (Table 4-2). Bottom feeder fillet
composites consisted of five black redhorse at Station 1; five common carp at Stations 2, 3,
4A, and 413; and five smallmouth buffalo at Station 5. In addition, a second bottom feeder
fillet composite, consisting of five channel catfish, was prepared for analysis from Station 4A;
and a second bottom feeder fillet composite, consisting of five flathead catfish, was prepared
for analysis from Station 4B. Bottom feeder whole body composites included five northern
hog sucker at Stations 1 and 5, five common carp at Stations 2, 3, and 4A, and four common
carp at Station 4B (Table 4-2).
Twenty-four of 26 composites submitted for analysis in 1999 met the US EPA Region IV
recommendation (Cunningham 1990) that the smallest specimen in each composite be equal to
or greater than 75 percent of the total length of the largest specimen in that composite (Tables
4-2 and 6-4).

5. SAMPLE PREPARATION
All fish tissue samples were prepared in accordance with U.S. EPA Region IV
recommendations (Cunningham 1990) as described in EA (1990). To prevent
cross-contamination between sampling stations, all sampling equipment likely to come into
contact with the fish was rinsed extensively with site water between stations.
Specimens collected at each station were sorted by size and species, and target species were
identified. The objective was to obtain four 5-fish composite samples at each station (plus a
catfish composite for each station in Waterville Lake) which met the species and size
objectives discussed in Section 3. From the target fishes collected, specimens of similar length
and weight were selected for each composite sample. All specimens retained were
immediately placed on ice for later processing. For each fish retained, length and weight data
were collected and recorded on the appropriate fisheries data sheet.
Following identification of target organisms, selection of composite samples, and collection of
length/weight data, each specimen was prepared for analysis and shipment. Sport fish and
bottom feeder fillet samples consisted of epaxial muscle tissue and skin from both sides of the
fish. Bottom feeder whole body samples consisted of the entire fish. Fillet samples were
prepared by removing the scales and then making an incision behind the opercula (on both
sides of the fish) from the base of the spine (behind the skull) to just below the pectoral fin.
Care was taken to cut through the epaxial muscle without puncturing the rib cage or gut lining.
A second incision was made along the length of the spine to the caudal fin on both sides of the
fish. The epaxial muscle was then gently cutaway from the rib cage to obtain a fillet. In this
fashion, all flesh and skin was obtained from head to tail on both sides of the fish. Fillet
knives were solvent rinsed (hexane and acetone) between fish from different stations. Each
sample was wrapped in aluminum foil (dull side toward sample), labeled, and placed on dry
ice. Right side fillets were sent to Quanterra Laboratories for analysis; left side fillets were
retained by Blue Ridge personnel as back-up fillets.
All individual specimens (fillets or whole bodies) composing a single composite sample were
placed together in a water-tight plastic bag labeled with the station name, sample number, and
the number of specimens in that composite. All labels contained the following information:
• sample identification number,
• sample location and station identification,
• sampling team initials,
• date of sample collection,
• species name,
• sample type (i.e., fillet or whole body)
• composite number (e.g., 1RF, 2RF,,etc; see Table 4-2), and
5-1

A chain-of-custody form was filled out for each set of samples submitted for analysis. Each
form included composite-specific information and instructions. Copies of all chain-of-custody
records are provided in Appendix A.
All samples were frozen solid prior to shipment to the analytical laboratory. The frozen
samples were packed on dry ice, shipped via overnight delivery on 12 August and received at
Quanterra Environmental Services Analytical Laboratory on 13 August 1999. All samples
arrived in good condition, still frozen (see chain-of-custody form in Appendix A).

j 6. ANALYTICAL RESULTS
The fish tissue samples were received at Quanterra Environmental Services Analytical
Laboratory, West Sacramento, California under chain-of-custody on 13 August 1999. Once
received at the laboratory, samples were compared to the chain-of-custody record to verify the
contents of each shipping container. Each individual fish or fillet within a composite was
homogenized separately by Quanterra personnel, and equal aliquots of the homogenate from
each fish were removed to constitute the composite. Dioxin and furan analyses were
performed using high resolution Gas Chromatography/Mass Spectrometry (GS/MS) as
required by the U.S. EPA. Laboratory documentation of all chemical extractions and analyses
are provided in Appendix B. _
All chemical analyses of fish tissue samples were conducted using EPA Method 8290 (U.S.
EPA 1994) as specified in the Canton Mill NPDES permit condition.
The quality of the Quanterra Environmental Services Analytical Laboratory analyses was
assured through reproducible calibration and testing of the extractions and GC/MS systems. A
laboratory method blank was prepared along with each batch of samples. The laboratory also
used precision and recovery standards for the determination of initial and ongoing precision
and accuracy.
Laboratory reports for all 1999 Pigeon River fish tissue dioxin, furan, and lipid content
analyses are provided in Appendix B. Each laboratory analysis report form lists the
concentration of 2,3,7,8=tetrachlorodibenzo-p-dioxin (TCDD), 2,3,7,8-tetrachlorodibenzofuran
(TCDF), and all other CDD/CDF isomers. Results of the dioxin, furan, and lipid content
analyses are summarized in Table 6-1. Detection limits are reported parenthetically on a
sample-specific basis. Only fillet results are discussed below because the North Carolina
Division of Environment and Natural Resources (NCDENR), formerly the North Carolina
Division of Environmental Management (NCDEM), considers only fillet results when issuing
health advisories.
Concentrations of 2,3,7,8-TCDD and 2,3,7,8-TCDF were below the level of detection for all
sportfish composite samples from all locations (Table 6-1).
Concentrations of 2,3,7,8-TCDD in bottom feeder composite fillet samples were below the
level of detection at Stations 1, 2, and 5 (Table 6-1). Concentrations of 2,3,7,8-TCDD in
bottom feeder composite fillet samples from Stations 3 through 4B ranged from 0.57 ppt (carp
at Station 3) to 4.7 ppt (carp at Station 4B). Furan isomer (2,3,7,8-TCDF) analysis results
indicated a concentration range from non-detect [Stations 1, 2, 4A (channel catfish), and 4B
(flathead catfish)] to 2.4 ppt (common carp at Station 4B) for bottom feeder fillets.
Examination of the data in Table 6-1 indicates that all fish collected during this study had body
burdens well below the FDA dioxin health advisory level (25 ppt) for fish tissue [as established
and presented in FDA (1981 and 1983) and Cordle (1983)].

NOTE: ND=Non-Detectable,DL=Detection Limit

NCDENR has identified a dioxin evaluation level of 3 ppt in fillet samples, expressed as
average toxicity equivalent (TEQ) (NCDEM 1991). The TEQ of each chlorodibenzo dioxin
and furan (CDD/F) isomer is based on the toxicity equivalence factor (TEF) (U.S. EPA 1989
and Table 6-2) as indicated in Part 3, other requirements (paragraph H) of the Canton Mill's
permit and as described in the 1990 Study Plan (EA 1990). The TEQ value is calculated
assuming additivity of effects from the individual congeners of dioxins and furans and is
expressed as an "equivalent amount of 2,3,7,8-TCDD" (NCDEM 1991). The measured
concentration of each CDD/F isomer, when multiplied by its appropriate TEF, yields the TEQ
of that isomer (the toxic concentration of that isomer relative to the toxicity of
2,3,7,8-TCDD). In cases where CDD/F concentrations were below the level of detection, a
value of one-half of the sample-specific detection limit was applied to the TEQ calculation.
The TEQ calculation and summarization schemes presented in Table 6-3 followed methods
used by NCDENR (NCDEM 1991). Sport fish fillet composites at all locations had TEQ
values well below the NCDENR evaluation level of 3.0 ppt. Bottom feeder fillet TEQ values
for all stations, except 4B in Waterville Lake, were also well below the NCDENR limit. The
TEQ value for the carp fillet composite at Location 4B exceeded the evaluation level.
However, the TEQ value for flathead catfish from the same location was well below the
NCDENR evaluation level of 3.0 ppt (Table 6-3).
Because dioxin and furan values for all sport fish fillet composites were below the level of
detection, TEQ values were calculated using one-half of the sample-specific detection limit.
Using this approach, TEQ concentrations in sport fish fillet samples ranged from 0.22 ppt at
Stations 4A to 0.84 ppt at Station 2 (Table 6-3).
Table 6-4 illustrates the consistent decline in 2,3,7,8 TCDD concentrations in fillet samples
from 1990 through 1999, particularly among bottom feeders (i.e., carp). From 1990 through
1994) 2,3,7,8 TCDD concentrations in fillets from bottom feeders declined by 82 percent at
Station 3; 87 percent at Station 4A; and 95 percent at Station 2, closest to the mill discharge.
Since 1994, 2,3,7,8 TCDD concentrations from bottom feeder fillets at Stations 2, 3, and 4A
have continued to decline. The concentration of 2,3,7,8 TCDD at Station 4B in 1999 was the
lowest observed since 1996 and the second lowest observed since 1990 (Table 6-4).
Concentrations of 2,3,7,8 TCDD in bottom feeder (i.e., carp) fillets from Station 4B have
declined consistently since 1997. The concentration of 2,3,7,8 TCDD in the bottom feeder
fillet sample at Station 4B in 1999 was 93 percent lower than that observed in 1990 (Table 6-
4). Thus, the overall trend from 1990 through 1999 is clearly downward at all stations and,
on average, concentrations in 1999 were the lowest since monitoring began in 1990 (Figure 6-
1).

Some internal standard recoveries are lower than the method recommended goal of 40%.
Generally, data quality is not considered affected if internal standard signal-to-noise is
greater than 10:1, which is achieved for all internal standards in all samples.
2,3,7,8-TCDF in sample 'BRP-LOC 1 NHOG S WB' was confirmed on a DB-225 column,
however, results should be considered estimated due to an interference at the same
expected retention time.
