Blue Ridge Paper Comments
Dear Mr. Wu:
Blue Ridge has submitted extensive information related to water quality in the Pigeon River
through the 2006 NPDES permit renewal process. Included in this information was the 2005
Balanced and Indigenous Species Study for the Pigeon River(CWA 316(a) Demonstration). The
2005 study meets submission criteria and Blue Ridge formally requests that this data be reviewed
as part of the basinwide water quality plan currently under development and before development
of the 2008 303(d) list. The study plan was submitted the Division of Water Quality in February
2005 and is included in Appendix E of the report.
The State Health Director lifted the fish consumption advisory on Waterville Lake on January 9,
2007. Blue Ridge requests that any reference to this body of water in the next basinwide plan
include this information. Data relevant to this decision was submitted in the 2005 Dioxin
Monitoring in Fish Tissue Report and the 2006 Dioxin Monitoring in Fish Tissue Report. The
lake was originally listed in 1998 as impaired due to the fish advisory. Due to the recent removal
of this advisory the lake should be removed from the list of impaired waters in 2008.
The 2005 B&I Study and the fish tissue reports constitute the Company's data submission of
water quality information relevant to the current basinwide water quality plan under development
(i.e. the 2008 303(d) list year). I have included the cover letters for the above mentioned data
submittal packages for your reference. If you have any questions or need further information
please contact us.

The University of Tennessee at Knoxville completed fish collection and the report. Fish
collection followed the December 2001 monitoring plan approved by DENR. Project details
were modified in 2006 to be responsive to the North Carolina Division of Water Quality. The
principal changes to the program in 2006 were the elimination of sampling of the main stem of
the Pigeon River beginning in 2006 and the collection of at least one whole body bottom feeder
sample from Waterville Lake (Stations 4A or 4B). These changes are included in more detail in
Appendix D. Severn Trent Laboratories completed the dioxin analyses.

2005 Study Plan—Canton Mill Thermal Assessment
Blue Ridge Paper Products, Inc.
Canton, North Carolina
CDear Mr. Haynes—
Enclosed is the subject plan required under Part I, Condition A.13 of the NPDES permit for the
Blue Ridge Paper Products mill in Canton, North Carolina.
Blue Ridge Paper is required to submit a thermal variance report under Section 316a of the Clean
Water Act as part of the May 2006 application to renew the NPDES permit for the Canton Mill.
We have selected a team lead by Dr.Larry Wilson of the University of Tennessee;Department
of Forestry, Wildlife and Fisheries to complete fieldwork and prepare the 316a Thermal Variance
Report.
Dr. Wilson and the University of Tennessee are key members of the Pigeon River Restoration
Project. The focus of this project is re-introduction of non-game species to the Pigeon River
following the substantial improvements in water quality associated with the Canton Mill
modernization in the 1990s. Re-introductions in the Tennessee portion of the Pigeon River
began in 2001 and were expanded to North Carolina portions of the river in 2004. The
restoration project is cooperative effort between state and Federal water quality and wildlife
agencies in Tennessee and North Carolina. The project receives funding support from both
public and private sources including Blue Ridge Paper. General information on the Pigeon
River Restoration Project is also enclosed.

Dr. Wilson and Blue Ridge Paper met with Mr. Bryn Tracy of the DENR DWQ Biological
Assessment Unit on January 19, 2005 in Knoxville, Tennessee. The purpose of this meeting was
to discuss the scope of the 2005 study and proposed changes from previous studies in 1995 and
2000. We greatly appreciate Mr. Tracy's input to development of the 2005 Study plan.
Please contact us if you have questions regarding this submittal. The project team will meet in
Knoxville, Tennessee on March 11, 2005 to develop fieldwork schedules and sampling method
training for the University field crews.

Subject: 2006 Integrated Report Comments—Follow up Biological Data
Pigeon River—Tributary to the French Broad River
Dear Ms. Chavis:
On March 2, 2006 Blue Ridge Paper Products, Inc. (Blue Ridge Paper)provided comments on
the public review draft of the North Carolina Water Quality Assessment and Impaired Waters
List(2006 Integrated 305(b) and 303(d)Report). In those comments, Blue Ridge Paper
requested that the Division review data collected by the University of Tennessee(UT) during
their biological assessment of the Pigeon River in 2005 and meet with us before finalizing the
status of the Pigeon River in the 2006 Integrated Report. These data are included as attachments
to this letter. The UT assessment was led by Dr. J. Larry Wilson—Professor and Interim Head
of the Department of Forestry, Wildlife and Fisheries and the benthic identification was led by
Dr.David Emier—Emeritus Professor,Ecology and Evolutionary Biology.
In our discussions with the Division, we understand that the proposed use support ratings of the
Pigeon River are heavily based on the biological monitoring that the Division performed in 2002.
It should be noted that 2002 was the fmal year of a prolonged drought in the region that started in
1998 and is an "unrepresentative"result for the Pigeon River,particularly the Division's
monitoring site at Clyde. When compared to the Division's past monitoring results,the 2002
results are a clear departure from the improved quality trends seen in the river beginning in the
early 1990s.
The attached 2005 data by the University of Tennessee when correlated to the Division's
biological rating criteria indicate that the benthic health of the river from Canton to Waterville is
Good-Fair or better. Therefore, we believe the Pigeon River should not be on the 303(d)list for
"Impaired Biological Integrity". Blue Ridge Paper submits that the results of the 2005 biological
assessment are relevant to the 2006 Integrated Report in that it brings to light the most recent
data on the river. As indicated above, the data collected from 2002 should not be used in the
2006 Integrated Report to describe conditions in the Pigeon River as it is unrepresentative of
conditions in the River in more recent years. Blue Ridge Paper believes that the Division should

Ms. Linda Chavis—NC DWQ
10 April 2006
consider the 2005 data on the River to finalize the assessment of the River in the 2006 Integrated
Report.
In the March comment letter, Blue Ridge Paper requested a meeting with Division staff to
discuss these issues and also offered the participation of the principle scientists that did the 2005
monitoring and analysis work for this meeting. Blue Ridge Paper continues to have interest in
meeting with the Division.
The 2006 Integrated Report is very important since it is a key part of the Division's view of
water quality improvements in the Pigeon River and is submitted both to EPA and available to
the public. Blue Ridge Paper certainly respects the efforts that the Division must make to update
this Integrated Report every two years and would like to aid in this effort by providing the
attached information for consideration.
Blue Ridge Paper will submit a river study, which will include a complete biological review of
the Pigeon River, to the Division by May 31, 2006 as part of its NPDES permit renewal package.
Please feel free to call us if you have any questions in this matter.

CERTIFIED MAIL
_RETURN RECEIPT REQUESTED
Ms. Linda Chavis 7099 3220 0007 0371 6174
Planning Section
NC Division of Water Quality
1617 Mail Service Center
Raleigh, NC 27699-1617
Subject: 2006 Integrated Report Comments
Dear Ms. Chavis:
Blue Ridge Paper Products, Inc. (Blue Ridge) is providing comments on the public review draft
of the North Carolina Water Quality Assessment and Impaired Waters List(2006 Integrated
305(b) and 303(d)Report). Comments provided below include and reflect the conversation
between Blue Ridge and Michelle Woolfolk(Division of Water Quality) and other Division
staff.
Blue Ridge and its Canton Mill operation have undertaken an aggressive and very successful
effort to improve the quality of the Mill's effluent and the water quality of the Pigeon River.
Over the last fifteen years,the Mill has undertaken tremendous efforts and invested great
resources in accomplishing these goals. We certainly respect the efforts that the Division must
make to update this Integrated Report every two years. Blue Ridge also knows that the Division
is well aware of these efforts and has been a huge part of the water quality improvements that
have been realized.
This Integrated Report is very important since it is a key part of the Division's view of these
water quality improvements and is submitted both to EPA and available to the public. In our
discussions with the Division, we understand that the current ratings of the Pigeon River are
heavily based on the biological monitoring that the Division performed in 2002. We would point
out that 2002 was the final year of a prolonged drought in the region that started in 1998 and
likely represents an"unrepresentative"result for the River,particularly your monitoring site at
Clyde. When compared to the monitoring results from 1997, the 2002 results are a clear
departure from the improved quality trends seen in the river beginning in the early 1990s. The
Mill's effluent quality has progressively improved over this entire period and Blue Ridge
continues to undertake more steps to further these efforts. Blue Ridge believes that the Division
should consider the most recent available data on the River to finalize these ratings.

Raising Your Expectations

Ms. Linda Chavis—NC DWQ
2 March 2006
The University of Tennessee at Knoxville completed a comprehensive biological monitoring
effort of the Pigeon in 2005. The report that presents those results is scheduled to be finalized in
May of this year. Blue Ridge respectfully requests that the Division consider this more recent
data under more "normal"hydrologic conditions. Blue Ridge would be glad to meet with
Division staff to discuss these issues. In addition we would offer to solicit the participation of
the principle scientists that did the 2005 monitoring and analysis work for this meeting.
Another concern is the"assessment unit" listings used by the Division. While we realize that the
Division's stream classification listing identifies only one index number for the Pigeon from
Canton to the State line, using this index number alone to describe this complex segment makes
it difficult for the reader to understand this segment and to link this report with past DWQ
reporting. The previous listings/reports from DWQ's web site for 1998, 2000,2002 and 2004 all
"break"the River into several assessments units. The Division should continue to use the
assessment units employed in the past for continuity and understanding.
Specific issue points on this report follow:
1. The report lists the"Pigeon River(Waterville Lake below elevation 2258)" on page 43 of
the 303(d) list. The reason for the listing is "Impaired biological integrity"due to the
current dioxin posting for the lake. Blue Ridge believes this designation is inappropriate
for the following reasons:
• The 1998, 2000, 2002, and 2004 reports all list Waterville Lake for"fish
advisory-dioxin". The reports do not list this issue as "impaired biological
integrity."
• Dioxin in carp has never been established as a biological impact to the carp, only
as a potential issue to humans who consume the carp.
• The 2005 French Broad River Basinwide Water Quality Plan (Chapter 5,page 67)
states that"Waterville Lake is on the state's 303(d) list of Impaired waters due to
the fish consumption advisory." The report does not mention "impaired
biological integrity" as an issue.
Based on the information available, Blue Ridge believes the only portion of the Pigeon
River that should be included on the 303(d) list is Waterville Lake. In addition, the
impairment to the lake should be consistent with previous 303(d) listings in which the
lake is listed due to the fish consumption advisory. Updated data on dioxin
concentrations in carp are enclosed for review.
2. If it is the intent of the Division to list only Waterville Lake on the 303(d) list, the
description of the impaired water should be changed. Currently the description reads
"From 0.15 miles downstream of W. Park St to State Route 1642 (Main Street)". The
current description should be changed to exclude any portion of the main stem of the
Pigeon River. The description should be consistent with other descriptions of the lake
(e.g. Page 4 of the list of Impaired Waters not Needing TMDLs) in which the lake is

described as follows: "From White Oak Road to Waterville Reservoir Dam"with the
appropriate number of FW acres identified.
3. The report also lists the Pigeon River in Table 3-18 "Waters Delisted from Categories 5,
6, and 7 (or the 303(d) list)". Blue Ridge agrees with the delisting the main stem of the
Pigeon River.
Please consider these comments when evaluating the final 2006 Integrated Report and contact us
if you have any questions or need additional information.

EXECUTIVE SUMMARY
The Blue Ridge Paper Products, Inc., Canton Mill contracted the Department of Forestry,
Wildlife and Fisheries of the University of Tennessee, Knoxville (UTK) to collect dioxin fish
tissue samples from the Pigeon River during the summer of 2005 in accordance with NPDPES
permit conditions. UTK field personnel followed the December 2001 Fish Tissue Sampling Plan
prepared by EA Engineering, Science and Technology, Inc., (EA Engineering 2001a) of
Chicago, Illinois. UTIC prepared this 2005 fish tissue sampling report using the template
developed by EA Engineering for prior reporting years.
Bottom feeding species were collected in 2005 from six locations in the Pigeon River and
analyzed for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 2,3,7,8-tetrachlorodibenzofuran
(TCDF), and other CDD and CDF isomers. TCDD and TCDF concentrations in fillet
composites from bottom feeders were very low(range=non-detect to 2.8 parts per trillion(ppt))
at all locations sampled. Fillets used for analyses were obtained from black redhorse, common
carp, and channel catfish. Chemical analyses were also conducted on a composite sample of
three common carp (whole body samples) collected from Station 4A and total TCDD and TCDF
concentrations were 2.1 and 1.3 ppt respectively. Percent lipid content of the tissues (fillets and
whole body) used for analysis ranged from a mean of 5.6% (fillets)to 13%(common carp whole
body). Tissue concentrations of 2,3,7,8-TCDD were consistent with values reported in 2004,and
the same conclusion drawn in 2004 can be applied to the 2005 results, i.e., that the concentration
of 2,3,7,8-TCDD in carp fillets from Waterville Lake has declined by 94-99 percent during the
period from 1990 through 2004(Figure ES-1). Dioxin concentrations in fish tissue samples from
all sites sampled in 2005 were below the FDA dioxin health advisory limit and the toxicity
equivalent limit of the North Carolina Department of Health and Human Services.

Ms. Williams,
Thank you for pointing out the error in the report. I have attached a revised Table 6-3 for your review. As you will
see, all results for 1,2,3,4,7,8,9-HpCDF were"non-detect"and did not change the TEQ calculations in the report.
The lab results are included in the hard copy of the report as Appendix B for your reference. I am sorry for the error
in the original table and will be sure that the table is complete for future sampling efforts. In addition, Blue Ridge will
provide the attached table with the 2006 sampling results report so that a more efficient comparision can be made.

Subject Review/comments 2005 Pigeon River/Waterville Lake fish sampling
Hello, Mr. Dickens and Mr. Rogers. I am Dr. Luanne Williams, a
toxicologist with the NC Department of Health and Human Services. Thank
you for sending me the August and September 2005 dioxin/furan congener
fish sampling results for the Pigeon River and Walters Lake/Waterville
Reservoir. The University of Tennessee Knoxville folks did a fine job
in presenting the results for 16 dibenzodioxin/furan congeners and
wouldn't expect anything less especially since this is my alma mater.
However, the results of one of the dibenzofuran congeners is missing for
all of the fish samples. Specifically, the dibenzofuran congener
1,2,3,4,7,8,9-HpCDF results were not reported. When reporting the 2006
fish sampling results, please include the results for this congener

along with the other 16 congeners currently listed in the 2005 report
(shown in Table 6-3) so that I can determine when and if the fish
advisory should be removed from Walters Lake/Waterville Reservoir.
Also, when reporting the 2006 sampling results for all 17 congeners
please provide the 2005 sampling results and TEQ levels for all 17
congeners for all fish sampled as shown in Table 6-3. The TEQ levels
for the two consecutive years should be provided as opposed to just
providing a graph so an'accurate comparison can be made. In order to
remove the carp fish advisory for Walters Lake/Waterville Reservoir, I
will need two dataset years showing TCDD TEQ levels at 3 pg/gm (ppt) or
less for carp. Call me if you have any questions at 919-707-5912.
