Waters may be excluded from the list if existing control strategies for point and nonpoint source pollution will achieve standards and uses. Listed waterbodies must be prioritized, and a management strategy or total maximum daily load (TMDL) must subsequently be developed for all listed waters. Background and Purpose Five freshwater segments, 5-(7)a to 5-(7)f, in the Pigeon River and Waterville Lake are listed on the 303(d) list for fish advisories due to contamination by dioxin. On the published North Carolina 1998 303(d) list there is a caveat listed for the Pigeon segments which states the following: "The Pigeon River remains on the list due to fish consumption advisories even though fish tissue data indicate declining levels of dioxins in fish. Controls have been placed on point sources upstream of the sampling locations and concentrations in fish are expected to continue to decline. DWQ will not develop a TMDL or further management strategies, however, dioxin levels in fish will continue to be monitored." Contrary to this statement, the North Carolina Division of Water Quality (DWQ) has decided to draft a TMDL in order to expedite the Pigeon River segments'and Waterville Lake's removal from the 303(d) list. Also, part of that statement is misleading as Champion International Mill in Canton, NC is the sole source of dioxin in the Pigeon watershed. Numerous isomers of dioxin exist and are monitored in fish tissue and in point source effluent; however, the isomer 2,3,7,8 TCDD (Tetrachloro-dibenzo-p-dioxin) is the one that is restricted in the effluent and will be the standard for this TMDL. In the TMDL, "dioxin" refers to 2,3,7,8 TCDD. It is also important to note that Champion has not measured detectable concentrations 2,3,7,8 TCDD since November, 1989. TMDL Development To develop a TMDL,DWQ employed a mass balance equation that considers the mean annual flow of the river, the design flow of the discharger, and the human health standard for dioxin to determine a maximum allowable effluent concentration. North Carolina's regulation for flow design criteria for effluent limitations, Procedures for Assignment of Water Ouality Standard 15A NCAC 2B .0206, requires use of"the mean annual flow to protect human health from carcinogens through the consumption of water, fish and shellfish unless site specific contamination concerns necessitate the use of an alternative design flow." Mass balance equation for dioxin in Pigeon River at Champion Intemational-Canton: CuQu + CwQw =CdQd where: Cu ='upstream concentration Cw =waste concentration Cd=downstream cone. (or standard in this case) . Qu= upstream flow Qw = waste flow (design flow) Qd =downstream flow (equal to Qu + Qw) 2 , If the equation is solved for Cw it yields a concentration that would meet the human health standard for dioxin downstream of the effluent. In other words, the TMDL should, at least, be below this concentration. Cw = (CdQd- CuQu)/Qw Qw =46.3 cfs (29.9 MGD x 1.547 cfs/MGD =46.3 cfs) Qu = 327 cfs (mean annual flow) Qd= 373.3 (Qw + Qu), Cu = 0 (assumed, since mill is only source in basin) Cd=0.014 pg/I (NC standard for human health) Cw = [0.014 pg/I (373.3 cfs) - 0 (327 cfs) ] /46.3 cfs Cw =0.113 pg/I So; the waste concentration must be less than 0.113 pg/I at mean annual flow for the Pigeon River to meet the North Carolina human health standard for dioxin. - Margin of Safety DWQ issued Champion an NPDES permit with a reduced dioxin limit in December, 1996 (Appendix I). The limit was designed to protect the human health standard for dioxin downstream of the discharge. The limit is 0.1 pg/l. To lend further perspective to this limit, a picogram is 10"14 gram; this is equivalent to saying that one penny (picogram) is equal to 10-14 times 1,000,000,000,000, or 1 quadrillion, dollars. If you substitute the permitted limit for Cw and solve for Cd, the dioxin standard is not violated: Cd= (CuQu + CwQw)/Qd Cd= [0 (327 cfs) +0.1 pg/I (46.3 cfs)] /373.3 cfs Cd=0.0124 pg/I The margin of safety may be calculated as follows (Cs =NC standard for human health, Cd from directly above, or downstream concentration at permitted limit): [(Cs -Cd)/Cs] * 100 =MOS [(0.014 - 0.0124)/0.014] * 100 = 11.4% Thus, there is an 11.4% margin of safety. Seasonality Seasonality is not considered to be an issue in the case of dioxin as it is aknown carcinogen. The duration of exposure assumed for carcinogens is over a lifetime. Dioxin is highly bioavailable and has a long half-life making it available throughout the year. While there may be more up-take of dioxin by fish in the summer months, inputs from the winter and fall still have the potential of impacting fish tissue concentrations throughout the year. 3 TMDL Calculation As explained above, Champion International is the only source in the basin, so it will receive the whole allowable TMDL load. This is manifest in its NPDES concentration limit of 0.1 pg/l. No other sources will be permitted to discharge dioxin into the Pigeon River or any of its tributaries. In the late 1980's Champion made two changes that resulted in the nondetect levels of dioxin in the facility's effluent: 1) It increased the level of chlorine dioxide substitution used for pulp bleaching and decreased the use of elemental chlorine; and 2) Champion changed the types of defoamers that were used in pulp bleaching. These defoamers have low levels of dioxin and furan precursors relative to the defoamers previously used. These changes resulted in nondetect effluent levels of 2,3,7,8 TCDD since November, 1989. In 1993 Champion converted both of their hardwood and pine bleaching processes to OD100 which is elemental chlorine free (ECF). The OD100 process includes oxygen delignification prior to pulp bleaching. Oxygen delignification reduces the amount of chlorine dioxide needed to bleach pulp. The OD 100 process goes beyond the requirements of EPA's Cluster Rule for paper and pulp-industry to minimize dioxin and other discharges. Implementation of Dioxin TMDL Champion International was issued an NPDES permit on December 12, 1996 that limited effluent dioxin concentrations to 0.1 pg/l (Appendix I). The permit states that "the�sample shall be analyzed in accordance with the appropriate method of analysis specified in Analytical Procedures and Quality Assurance for Multimedia.Analysis of Polychlorinated Dibenzo-para-dioxins and Plychlorinated Dibenzofurans by High Resolution Gas Chromotoeraphy/High Resolution Mass Spectrometry, EPA, 1987 (EPA Method 8290), or another equivalent analytical protocol approved by DWQ." Monitoring shall be performed on a quarterly basis in four areas of the facility: influent to wastewater treatment facility, sludge, landfill leachate and effluent. A problematic situation arises in the laboratory analysis, however, as the analytical detection limit is 10 pg/l, while the permitted limit is 0.1 pg/l. The possibility exists that Champion could exceed the permitted limit but escape detection. The fish tissue analysis, explained in the following paragraph, provides some assurance that dioxin levels in the Pigeon River have, indeed, been decreasing. The NPDES permit also requires that Champion perform fish tissue analysis in accordance with a DWQ approved monitoring plan. Fish tissue analysis between 1990 and 1998 have shown declining levels of dioxin (Appendix II). During 1990 and 1991, detectable levels of dioxin occurred in nine of fifteen samples each year. Moreover, detectable levels were measured in redbreast sunfish, largemouth bass, and bluegill, as well as bottom feeders. By 1993, four out of, fifteen tissue samples yielded concentrations above detection. Detectable concentrations-were observed in non-bottom feeders (largemouth bass] as late as 1995. Since 1996, the only species to contain detectable dioxin levels have been.bottom feeders such.as common carp, channel catfish, and flathead catfish. In 1998,_only common carp showed detectable levels in three of fifteen samples; flathead catfish and channel catfish had nondetectable levels of dioxin. DWQ recommends that contaminated sediments in the Pigeon River and.Waterville Lake remain undisturbed so that they may be "capped" by sedimentation. As demonstrated, this strategy and 4 the reduced effluent concentration have proven to be successful-at reducing fish tissue concentrations. Public Participation There was a public meeting on June 6, 1996 to gamer public input on Champion's NPDES permit,. which contained a limit for dioxin. This meeting was noticed at least one month prior in several newspapers in the region. At EPA's request, DWQ could renotice this limit as a TMDL during the coming Basinwide planning meetings scheduled for fall 1999. . �a Tracking Progress As explained in previous sections, effluent dioxin is monitored on a quarterly basis and fish tissue analyses are conducted annually. The existing NPDES permit will expire on November 30, 2001. The necessity for fish tissue analyses and effluent monitoring will be reevaluated in the next NDPES permit. 1 5 Making Or mark for you.

THE BACK �a SEP 1 1 1997 r j Champion N pora ton September 8, 1997 Mr. Mike McGhee US EPA, Region W 61 Forsyth Street Atlanta,GA 30303 Subject: Draft Report entitled"Ecological Assessment of the Pigeon River and Waterville Reservoir dated 7/16/97. Dear Mike: Thank you for the opportunity to review the subject draft report prepared by Dave Melgaard and presented to us on July 17, at a meeting of the Technology Working Group in Atlanta. Champion has serious concerns about not only the tone of the report, which tends to dwell too much on the past history of the river and the mill,but also because it conveys the idea,as if it were fact,that there are still serious problems in the receiving stream. Every single study that has been made of the ecology of the Pigeon River since the Canton mill modernization, whether by Tennessee, Oak Ridge National Labs,North Carolina, Carolina Power and Light or Champion, shows significant improvement in species diversity, abundance and fish body condition. And each following study shows more favorable results than those done in previous years, i.e. the river continues to improve with time Dioxin body burdens in fish show a steady and consistent decline, and both states have revised their fish advisories to reflect this improvement (the report only acknowledges that North Carolina has revised its advisory). Tennessee uses a more restrictive dioxin criteria for its stream advisory on the Pigeon than it does for other Tennessee streams, and if this were not the case, it is doubtful that there would be any advisory on the Pigeon river within Tennessee. The report states "concerns have been expressed . . . about the presence of dioxin in the sediments in Waterville Lake". As you know,this issue was addressed at great length in the last FERC relicensing of the CP&L hydroelectric facility. Several restrictions were placed on CP&L to ensure that sediments were not released from Champion International Corporation Mr. Mike McGhee U.S. EPA, Region IV September 8, 1997 Page 2 Waterville reservoir, and it was agreed that continued monitoring of fish flesh was the surest means of ensuring this result, as it was expected that over time the contaminated sediments would be covered with clean sediments. Both Tennessee and North Carolina, as well as EPA agreed to these conditions as a part of their"sign off' of the new license. All indications are that this control mechanism is working as evidenced by the trend downwards in fish flesh results. To our knowledge not a single bit of scientific evidence has been offered to support these"concerns". To the contrary, everything that has been done to investigate the basis for concern has shown none. This includes an investigation by the Health departments of both states concerning alleged high cancer incidents in Hartford, TN and the area around Canton,NC that showed no statistically significant difference in cancer mortality in either area when compared to other similar populations; a finding by EPA of the absence of dioxin in drinking water supplies in the Hartford, TN area; and an assessment by EPA's Agency for Toxic Substances and Disease Registry of possible routes of human exposure to dioxin from the Pigeon River that concluded that contact with, or consumption of water from, the river does not represent a significant human exposure pathway. Many of these points, incidentally, were made by John Hankinson is his Aug. 29, 1996 letter to David Jenkins (copy attached) replying on behalf of the EPA Administrator to questions about the proposed NPDES permit.. In summary, there is no new evidence (or old evidence, for that matter), and there are no new issues that have been presented. All the issues previously raised by the same concerned parties have already been addressed by EPA,FERC and the two states. Why then is there a need to initiate a new look at these same issues? It would seem that all that needs to be done is to compile the many studies of the river that have been done, and summarize the conclusions drawn from the studies. If, however, EPA has already decided to initiate this new study, it is imperative that any data or studies reviewed be carefully screened to ensure that they are comparable. For example, different Index of Biological Indices (IBI's) are used in several of the aquatic life studies. Secondly, any procedures used to collect new data must be proven and certified. In this regard,the possible use of semipermeable membranes being promoted by U.S. Fish and Wildlife as passive monitors and mentioned in the draft report would not meet this criteria. We have researched this method and understand it has not received an official approval as a test method. Secondly, its use is suggested as a surrogate for actual fish flesh data, in cases where fish cannot be collected for various reasons. Certainly,this is not the case for this river system given the tremendous amount of actual fish data that have been collected by the various entities. C• ampion International Corporation Mr. Mike McGhee U.S. EPA, Region IV September 8, 1997 Page 3 Champion believes the scope of study envisioned in this draft report is not justified, and we request you seriously consider our comments. If there are any questions please let me know. Sincerely, hEOyC/kys Attach.

Your letter has been referred to me for a response. As background, please be aware that NPDES permitting authority for this discharge now resides with the State. Also, variances for color and temperaE'ure must first be approved by the State. I understand that the State will make determinations on both the permit and the variances sometime this fall. The Environmental Protection Agency's (EPA) role is to overview the State' s draft permit to ensure that the goals of the Clean Water Act (CWA) are met and to separately review and approve any variance(s) . I am enclosing for your information a copy of this office's recent• comments on the State's draft permit. You raised a number of different concerns that I would like to address individually. Regarding the color variance, -you requested that this office consider the adverse economic implications that its continuation woa13- have on dowii`streaai'business interests and property owners during our- review of any State-approved variance. We do not have any current information on the number of tourists or recreational users that visit area rivers .such as the Nantahala, Chatooga, and/or the Ocoee or projections concerning the Pigeon River. We also do not have any. information about the number of dollars spent on activities related to recreational or other uses of these, rivers. If you could provide such information, we would be glad to consider it when we evaluate any future State-approved variance. z You also requested that the color variance be denied now or allowed only until the end of the decade, both resulting in a 50 color unit limit applied to Champion' s discharge pipe. As background, please note that the variance must be re-approved ever} three years . Champion requested and received a continuation of the color variance from North Carolina based on economic costs and lack of available technology to meet the State' s water quality criterion between the discharge point and the Tennessee state line. Such a variance is allowed under both North Carolina law and the Clean Water Act and its implementing regulations . For your information, I have enclosed sections from the EPA guidance Water Quality Standards Handbook and from 40 Code of Federal Regulations §131 . 10 regarding variances . This office approved North Carolina' s action in November 1994 . Please refer to pages 4 and 5 of our enclosed comment letter to North Carolina regarding the color provisions of the Champion draft permit . Regarding dioxin, you expressed concern that -eater releases from Waterville Reservoir after exposure to contaminated sediments may impact recreational users of the river. For several reasons, I do not believe that potential recreational exposure to dioxin in the water column represents a threat to human health. In December 1988, at this office' s request, the Agency for Toxic Substances and Disease Registry, a branch of the Department of Health and Human Services, conducted an assessment of possible routes of human exposure to dioxin from the Pigeon River. The assessment concluded that contact with, or consumption of water from, the river does not represent a signi6icant human exposure pathway. I am enclosing a copy of that report for your information. Also, EPA' s draft national assessment of dioxin does not consider dermal exposure to be a significant human pathway. If dioxin was contained in water releases from the reservoir, one would expect it to accumulate in the tissue of downstream fish. However, current dioxin levels in fish are generally lower than 5-7 years ago. Due to this improvement in water quality, North Carolina has lifted its 1989 fish advisory for top-feeding fish and Tennessee revised its existing fish advisory in March 1996. You also requested that a plan be developed to deal with these dioxin-contaminated sediments and that Champion pay for its development. Waterville Reservoir has already been assessed by this office as a potential Superfund site. Because of its long distance downstream from the Champion discharge and the partial lifting of the North Carolina fish advisory, the reservoir was not listed as a Superfund site. It is our best judgement that the most environmentally protective solution is to allow cleaner sediments to continue to build up, cover, and isolate the more contaminated, deeper lake sediments. In our view, any dredging or removal of the deeper contaminated sediments would release dioxin back into the lake' s water column, cause increased dioxin buildup in fish and other aquatic life tissue, and contaminate downstream segments of the river. j 3 Regarding oxygen-demanding wastes, you requested that they be treated so that the river can meet dissolved oxygen standards to support aquatic life. Protecting aquatic life and meeting both North Carolina' s and Tennessee' s dissolved oxygen standards is the basis for the current permit' s 5-day biochemical oxygen demand (HODS) limits and requirements to provide side stream oxygenation and monitor for dissolved oxygen at three different stations on the Pigeon River. The proposed permit' s BODS limits are even more stringent than those of the current permit and should maintain dissolved oxygen water quality standards in the river in both states . Regarding the temperature variance, please refer to pages 3 and 4 of our enclosed comment letter to North Carolina cited above . You indicated that this office is allowing the degradation of the Pigeon River to ccntinue to perpetuity. You also indicated that this office has =_=ad vic_aticn of the intent of = e C%71 and has not made any' real attempt to enforce its intent with respect to this discharge and the Pigeon River. I must strongly disagree with these assertions . Prior to the 1989 NPDES permit issued by this office, Champion had neither dioxin nor color limits. Champion has been and is currently complying with both the color and dioxin provisions of that permit. Color levels at the North Carolina/Tennessee state line are now consistently in the 10- 30 color unit range (the standard is 50) . To express these color levels in more common terms, the Pigeon River has improved from a consistent coffee'color to a ginger ale color. As cited above, both North Carolina' s and Tennessee's dioxin fish advisories have been modified. I believe that these all indicate a vast improvement in the water quality of the Pigeon River and that this office had a large part in this achievement. It is my intent that any new permit for Champion issued by North Carolina retain and improve on the environmental gains that we have already made. I believe that our enclosed comments on the proposed permit are also consistent with that goal. Please contact me if I can be of further assistance. Sincerely, John H.

Since 1990 annual fish tissue surveys of the Pigeon River have been conducted in August by the Canton Mill. EA Engineering Science and Technology, Inc. has collected all of the fish tissue samples. While the name has changed the same laboratory in Sacramento, California (Enseco 1990-1994, Quanterra 1995-1999, Severn Trent 2000) has conducted all of the fish tissue analysis.

The toxicity equivalency factors (TEFs) are from the World Health Organization (WHO/97, van Leeuwen, 1997) and applied to all 17 CDD/F isomers. As we discussed, a value of zero was applied to the toxicity equivalence calculation (TEQ) when the CDD/F isomer concentrations were below the level of detection. As shown in Attachment III, all sport fish in North Carolina have been below the level of detection for all 17 CDD/F isomers since 1996 (Station 5 is in Tennessee). The TEQ's for all catfish are either zero or below 3ppt. The TEQ's for carp in the main stem of the Pigeon River are also below 3ppt. However, the TEQ's for Stations 4A and 413, in Walters Lake, remain above 3ppt. This data, which includes the more recent TEF's and all 17 CDD/F isomers, support revision of the fish consumption advisory for dioxin in the Pigeon River.

Stevens 7 Division of Water Quality MEMORANDUM i To: Jimmie Overton Forrest Westall J 4 20 J ll k Through: Trish MacPherson - WATER QUALITY SECTION From: Bryn H. Tracy 04Vv _ SHEVI L REGIONAL OFFICE Subject: Comments on the NPDES Permit No. NC0000272, Blue Ridge Paper Products Inc., Canton Mill, Balanced and Indigenous Species Study for the Pigeon River I have reviewed this study and my comments are provided herein: 1. This study was required by NPDES permit, but the work was not performed by a NCDWO-certified laboratory. 2. In a letter from Ms. Coleen Sullins to Mr. Robert Williams (Blue Ridge Paper Products, Inc, (BRP)), it was specifically stated: "Task 1 --It is important to select species for modeling, which are native to the Pigeon River basin." And in an e-mail from me to Keith Haynes (dated March 17, 2000), 1 specifically requested: "Task 1 -- Species chosen for study should be those native species currently inhabiting the Pigeon River orspecies that were known or suspected to have occurred in the river prior to mill operation but no longer occur in the river due to mill operation. The importance of modeling species native to the French Broad River and Pigeon River basins can not be over emphasized." Two of the species (common carp and redbreast sunfish) which were modeled are not native to the basin and should not have been modeled. Other species, such as the river chub, mottled sculpin, and banded sculpin should have been. NC DWO was not given the opportunity to comment on the species chosen for modeling. 3. In the same letter and e-mail, it was stated: "It is our findings that there are currently no nuisance species in the river. And, . . ."to my knowledge, there are no commercially important or nuisance species in the river. Common carp should not be modeled as a nuisance species. Consultant should define nuisance species". The consultant never defined nuisance species prior to the study and common carp should not have been modeled as a representative important species. My use of the word: "nuisance" was based upon their study plan,where they stated: ". . . and one species that has the potential to become a nuisance species". My definition or understanding of "nuisance' was different than BRP's definition. 4. In the same letter and (more emphatically) in the same e-mail it was stated: "The NCIBI should not be used as its metrics were not calibrated nor was it correctly designed for streams the size of the Pigeon River'. Despite this, the 1995/1997 version of the Index was used. Conclusions based upon the 1995/1997 Index and its metric criteria were not and are not currently valid. 5. Page 1-2-- "By the mid-80's the aquatic life in the river was consistent with the expectations for a Class C stream in North Carolina (EA 1988)". This statement, which was repeated in 1990s reports,was pointed out in 1996 to BRP (at that time Champion International Corp.) that their interpretation of the regulations was in error and this statement was not true. e*o tJuDENR Customer Service Environmental Sciences Branch 1621 Mail Service Center Raleigh,NC 27699-1621 (919)733-9960 1 800 623-7748 V' 7 rvucna=i r casiey \O� \�•QG Governor CO ,7 William G.Ross.Jr..Secretary --r Department of Environment and Natural Resources YL O < Kerr T.Stevens Division of Water Quality 6. Page 3-1 -- If recolonization sources are lacking downstream of the mill and because the darter fauna in the Pigeon River has been severely impacted for many decades, would BRP (and other responsible entities and interested parties) fund efforts to reintroduce species that were eradicated by the mill's effluent and prevented from recolonization by the Walters Dam? 7. Pages 3-2 and 3-3 -- "Species richness in the most thermally affected zone (Fiberville) is comparable to upstream of the mill and better than the NC zones further downstream" --this maybe true, but the species (and their abundances) above and below the mill are entirely different. Later (buried in the report), Table 4-7 shows that the fauna of the most thermally affected site is only 16% similar to that of the reference site. Equating equal species richness at the two sites with having no thermal impact and indicative of a balanced fish community below the mill is not valid. S. Pages 3-2 and 3-3 --common carp and redbreast sunfish are not native to the Pigeon River basin and both species are considered tolerant. Nuisance species, as requested in an earlier correspondence, was never defined. 9. Pages 3-2, 3-3, and 3-9-- redbreast sunfish is a thermally tolerant fish whose percent abundance progressively declines the further removed from the mill (refer to Table 4-2). Above the mill, the species constitutes only 2.5%of the fauna, at Fiberville 64%, and at River Mile 19.3, 0%. Contrary to the report, this species clearly indicates that nuisance species are dominant and the community, at certain sites, is dominated by thermally tolerant species. Likewise, biomass data (page 4-15) also show the dominance of these two species in the nearfield areas (53%-68%). 10. Page 3-3 -- YOY (young-of-year) should not be collected and should not be considered when using the NC IBI (or any other version). 11. Page 3-4 -- as earlier stated, the NC IBI should not have been used as a measure of community health or as a tool to assess thermal impacts. 12. Page 3-4 -- if the upstream site is used as the reference site (a thermally unimpacted site), then downstream sites clearly show spatial faunal differences that can be attributed, at least in part, to temperature differences. 13. Page 3-5--what is BRP's evidence (basis) that the river below the mill should not be cool water system, like it is above the mill? The elimination of darters and other species was most likely due to extremely poor water quality(in the broadest sense including chemical and thermal pollutants). The recovery below the mill in North Carolina of the greenside darter, greenfin darter, tangerine darter, and other species will likely take a long time, if ever. 14. Page 3-9 --species richness conclusion --this is clearly a misinterpretation of the data. 16. Page 3-10 -- Competitive Advantage to Certain Species -- Redbreast sunfish seemed to dominate the communities below the mill. Would not this species decrease and rockbass increase if the temperature below the mill was cooler? 16. Page 3-11 -- Community Dominated by Thermally Tolerant Species -- "Furthermore, most citizens and anglers probably consider the presence of large numbers of redbreast sunfish to be a positive attribute of the fish community rather than a negative one." This clearly is an opinion and not supported by any published facts. The redbreast sunfish is not native to the mountain streams and is a indicator of some past alteration to the stream and community. In eastern Tennessee, this species is implicated in out-competing and displacing the native longear sunfish (Etnier and Starnes 1993. This presence and abundance of the redbreast sunfish in mountain waters should not be viewed as a positive attribute. -A NM MR Customer Service Environmental Sciences Branch 1621 Mail Service Center Raleigh,NC 27699-1621 (919)733-9960 1 800 623-7748 0/rrQG v may Governor 1 0) 1 r William G. Ross.Jr..Secretary > f JM, Department of Environment and Natural Resources Kerr T.Stevens Division of Water Quality 17. Page 3-13--Common Carp -- "The state has already stated that common carp is not a nuisance species in the Pigeon River(memo from Bryn Tracy dated 17 March 2000)." The exact wording of my memorandum was: "To my knowledge, there are no commercially important or nuisance species in the river. Common carp should not be modeled as a nuisance species. Consultant should define nuisance species." I believe my words were taken out of context and meaning. 18. Page 3-15 -- Redbreast sunfish -- "Since this is a popularspecies with anglers, it is expected that most people would view its increased abundance downstream of the mill as a positive rather than an adverse impact." Clearly, this is an opinion and not based upon published facts. 19. Pages 3-15 and 3-16-- Darters -- The presence of one or two individuals of any species of darters (or any other species) downstream of the mill does not equate with viable populations and with improving and tolerable conditions. 20. Appendix A, Page 1-1 -- "The North Carolina Division of Water Quality(NCDWQ) does not have an established protocol for conducting 316(a) demonstrations (email from Mr. Bryn Tracy date 116100). Nonetheless, biological sampling was conducted in accordance with standard NCDWQ field protocols." The precise wording of my e-mail was: "The North Carolina Division of Water Quality does not have a formal protocol for conducting 316 (a) demonstrations such as the one being proposed for the Pigeon River. Typically, the Division handles the study design on an informal communicative basis. You would, however, be safe in using the federal protocol and having use approve the study design before the actual sampling is to be conducted later this year. In terms of the benthic invertebrate community, the thermal effluent is treated just like any other WWTP effluent and upstream-downstream type studies are done." In a later email (dated 03/17/200) and in a letter from Ms. Sullins, BRP was instructed not use the NCIBI in its 316 (a) demonstration. 21. Appendix A, Page 2-12-- "For this report, the Of is used only to compare the 1995 and 2000 results". This statement is not valid. The inaccurately-derived Index is used to support BRP's position that a continuation of the variance is warranted. 22. Appendix A, Page 4-8 -- "No single species dominate the mainstream catch." The redbreast sunfish's abundance, below the mill in North Carolina, constituted 64% (near field) to 17% (far field) of all the fish collected. Approximately 25% of all the fish collected from the entire river were the.tolerant redbreast sunfish. 23. Appendix A, Page 4-11 -- Percent Similarity-- as mentioned earlier, the thermally affected sites below the mill were very dissimilar to the thermally unimpacted reference site. 24. Appendix A, Page 4-26 -- Life Stage and Spawning Activity--This assessment should have been made on a site-by- site basis, not for the entire river from River Mile 64.5 to River Mile 19.3. Young-of-year should also not be included in the analyses.

Easley, Governor NCDENR William G. Ross, Jr., Secretary Gregory J. Thorpe, Acting Director August 3,2001 O Mr.Robert Shanahan Vice President-Mill Manager Blue Ridge Paper Products P.O. Box 4000 Canton,North Carolina 28716 Subject: NPDES Draft Permit Permit No.NC0000272 Blue Ridge Paper Products Inc. Haywood County Dear Mr. Shanahan: Blue Ridge Paper Products Inc.applied for an NPDES permit renewal on February 26,2001. The Division of Water Quality's original schedule for conducting a public hearing prior to July 31,2001 was postponed in order to allow the EPA Tech Team and the Technology Review Workgroup the necessary time to incorporate the findings of a third party evaluation of the Canton Mill,sponsored by the Clean Water Fund of North Carolina,American Canoe Association,Western North Carolina Alliance,Dead Pigeon River Council,Appalachian Voices,Tennessee Environmental Council,Southern Appalachian Biodiversity Project,Dogwood Alliance and the National Forest Protection Council. The EPA Tech Team has completed their report and provided the Technology Review Workgroup with the`potential' color reductions available through the application of the identified process improvements. Based on this report,the Technology Review Workgroup developed the 'regulatory' basis for additional color reductions in this permit cycle. Now that the EPA Tech Team and the Technology Review Workgroup's color recommendations are final,the Division of Water Quality has prepared this draft permit and scheduled a public hearing for September 6,2001 (additional details below). After issuing a"pre-draft'permit,the Division of Water Quality prepared this draft permit and is once again soliciting comments from the Environmental Protection Agency,the State of Tennessee,the City of Newport, Cocke County,and other concerned stakeholders. The Division reviewed and considered all comments received during the"pre-draft"comment period and modified the"pre-draft"permit and fact sheet accordingly. The modifications reflected in this draft permit include the following: • The dioxin monitoring special condition has been modified. The dioxin monitoring special condition in the pre- draft permit allowed the permittee to split samples. If the analysis of either sample was below the minimum level,then the quality was considered zero for compliance purposes. The Division received concerns over this allowance and has modified the condition accordingly. The decision to split samples is at the discretion of the permittee,if samples are split,the permittee must report both values and compliance shall be judge on each sample independently. • Dates that have passed have been deleted from the Best Management Practices Special Condition. • Special Condition A. (8.)Requirements for Color Analysis and Compliance have been added. Based on the recommendations of the Technology Review Workgroup and the EPA Tech Team Report,the Division of Water Quality has developed the recommendations for additional color removal over the term of the permit. The color reductions contained in this condition represent a 19%to 29°/"reduction in the current permitted color load. After Blue Ridge Paper has implemented the process improvements necessary to achieve color reductions within the targeted range,Blue Ridge Paper will evaluate the feasibility of complying with North Carolina's 1617 MAIL SERVICE CENTER,RALOOM, NORTH CAROLINA 27699-1617-TELEPHONE 919-733-5083/FAX 919-733-0719 AN EQUAL OPPORTUNITY AFFIRMATIVE ACTION EMPLOYER-50%RECYCLED/10%POST-CONSUMER PAPER VISIT US ON THE INTERNET @ http://h2o.enr.state.nc.us/NPDES Permit Number: NC0000272 color standard. Then during permit renewal process in 2006,the Division of Water Quality and the NPDES Committee will evaluate what additional reduction,if any,are required in order to achieve compliance with North Carolina's color standard. Below are the Division's responses to comments received on the pre-draft permit. ➢ There were concerns over the language in the Best Management Practices Special Condition,these include: - Special Condition A. (6.)Section A. 1,the wording"to the maximum extent possible as determined by the mill. The language and conditions set forth in the Best Management Practices Special Condition were developed by the EPA as part of the new Effluent Guidelines for the Pulp and Paper Industry. After extensive research and gathering of public comment,the EPA stipulated an industry standard for Best Management Practices. The language contained in Special Condition A.(6.) is consistent with the industry standard as published in the Code of Federal Regulations. Since Blue Ridge Paper meets or exceeds the Best Management Practices standards,the Division does not feel that requiring a higher standard is justified at this time. - Special Condition A. (6.)Section E.3,the language"failure to take the actions required by Section E.2 as soon as practicable will be a permit violation". The comment was made that this language is unenforceable. In addition to the comment made for Special Condition A.(6.)Section E.3,it is the Division's understanding that the language in Section A. (6.)E.3 "failure to take the actions required by Section E.2 as soon as practicable will be a permit violation",is a`good faith' condition and that any gross violations of this condition are enforceable. - Monthly reporting of'action' level exceedence was recommended. In addition,to the comment made for Special Condition A.(6.)Section E.3,please refer to the Best Management Practices Special Condition Paragraph E. This condition requires that Blue Ridge Paper submit an annual report to the Division of Water Quality that summarizes Best Management Practices monitoring and action levels. The longer time frame(annual as opposed to monthly)associated with the annual submittal required in Special Condition A.(7.)provides the Division with a more representative analysis of operations at the mill and is better suited for analysis and conclusions. Therefore,the Division feels that annual reporting is appropriate. Comments were made regarding the daily maximum BOD5 limit proposed in the pre-draft permit. The Division's review of the instream dissolved oxygen data indicates that the limits and conditions in the permit are protecting the dissolved oxygen standard in the River. Additionally,the Division's model predicts and actual data supports that the lowest dissolved oxygen concentrations occur at river mile 57.7,which is above Hepco. The Division received comments regarding the need for nutrient limits in permits above the lake. The Division has no evidence that nutrients are a concern in this watershed. Additionally,Blue Ridge Paper's nutrient loading is relatively low,however,nutrient monitoring will continue as a condition for this permit in order to assess Blue Ridge Paper's nutrient loading to the River. The Division received comments regarding the removal of the monitoring station at river mile 53.5. Blue Ridge Paper currently is monitoring color,temperature,and dissolved oxygen at river mile 53.5. Temperature and dissolved oxygen monitoring at this point is required according to the NPDES permit issued to the City of Waynesville. Since Waynesville is already required to monitor this station, it is the Division's recommendation that additional monitoring of temperature and dissolved oxygen by Blue Ridge Paper is not appropriate. The color monitoring at this station was originally implemented in order to assess the impacts from Clyde's,the Waynesville and Richland Creek. With the removal of Clyde's discharge,the Division feels that the continued monitoring of color at river mile 62.9 (Fiberville)and river mile 42.6(Hepco) is sufficient. D The Division received a request to require dioxin isomer monitoring of the octachlorinated dioxin isomers at the internal outfalls,sludge and landfill leachate. The Division also received opposing comments suggesting that the dioxin and furan monitoring proposed in the pre-draft unnecessary. During the previous permit cycle,Blue Ridge Paper was required to monitor 15 isomers of dioxin and furans. Based on a review of this data and the Permit Number: NCOOOO272 public comments received,the Division recommends continued monitoring of 2,3,7,8,TCDD and 2,3,7,8 TCDF on the effluent,sludge,landfill leachate,and the influent to the wastewater treatment plant. Please review the draft permit and fact sheet carefully and submit comments to DENR-DWQ NPDES Unit. This draft permit should not be interpreted as the Division and NPDES Committee's final decision. A 30-day public comment period follows the release of this draft permit and will close at the discretion of the hearing officer and will be announced at the beginning of the public hearing to be held on September 6,2001. The details on where and when the hearing will be held is listed below: Public Hearing on regarding the Blue Ridge Paper Products Canton Mill's NPDES discharge will be held: September 6,2001 @ 7:00 pm at the Tuscola High School Auditorium 564 Tuscola School Road Waynesville,North Carolina Haywood County If you have any questions concerning the draft permit for your facility,please call me at(919)733-5083, extension 508.

As part of the engineering review,the permittee must determine whether existing spent pulping liquor containment facilities are of adequate capacity for collection and storage of anticipated intentional liquor diversions with sufficient contingency for collection and containment of spills. The engineering review must also consider: (i)The need for continuous, automatic monitoring systems to detect and control leaks and spills of spent pulping liquor, soap, and turpentine; (ii)The need for process wastewater diversion facilities to protect end-of-pipe wastewater treatment facilities from adverse effects of spills and diversions of spent pulping liquors, soap, and turpentine; (iii)The potential for contamination of storm water from the immediate process areas; and(iv)The extent to which segregation and/or collection and treatment of contaminated storm water from the immediate process areas is appropriate. 4. The permittee must amend its BMP Plan whenever there is a change in mill design, construction, operation, or maintenance that materially affects the potential for leaks or spills of spent pulping liquor,turpentine, or soap from the immediate process areas. 5. The permittee must complete a review and evaluation of the BMP Plan five years after the first BMP Plan is prepared and,except as provided in Section B.4., once every five years thereafter. As a result of this review and evaluation,the permittee must amend the BMP Plan within three months of the review if the mill determines that any new or modified management ractices and engineered controls are necessary to reduce significantly t like ood o�spent ulpin liquor,soap,-and rptu�leaks, spills, or intentional diversions from th immedi t pro areas me udingIa�schedule for implementation of such practices and ontrols.l �� 6.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON,D.C.20460 XMEMORANDUM DATE: July 25, 2001 SUBJECT: Additional Color Removal Technologies and Their Economic Impacts on Blue Ridge Paper Products, Canton,NC FROM: EPA Tech Team' TO: Technology Review Workgroup Purpose of this Analysis As required by the 1997 Settlement Agreement,this memorandum presents a summary of an analysis of available technologies that may be employed to further reduce color discharges from the Blue Ridge Paper Products, Inc. (Blue Ridge)mill in Canton,NC. The analysis also includes a summary of the economic impact("gross margin test") of the cost of implementing identified color reduction technologies. Members of the Tech Team visited the Canton mill on March 14, 2001 to observe and gather information and data on the status of technologies implemented and color discharges at the mill since the 1997 evaluation. This final memorandum incorporates analyses of the data gathered from that visit, and Blue Ridge's response to EPA's follow-up request for additional technical and financial data. This final memorandum is based on the May 4, 2001 preliminary draft memorandum, and revisions to the July 10, 2001 draft final memorandum, based on a review of Blue Ridge's comments,the June 8, 2001 Bleach Environmental Process Evaluation and Report (BEPER) and subsequent comments by Liebergott and Associates and GL&V Pulp Group, Inc, and additional comments from the Clean Water Fund of North Carolina, and the States of EPA Tech Team is comprised of--Mark Perez,EPA/EAD;Karrie-Jo Shell,EPA Region 4;Don Anderson, EPA/EAD;Betsy Bicknell,ERG,contractor;Neil McCubbin,subcontractor to ERG;Dan Bodien,subcontractor to ERG. Tennessee and North Carolina. This memorandum presents to the Technology Review Workgroup (TRW)process improvements evaluated by the Tech Team and considered to be available technologies and briefly addresses relevant technologies evaluated in the BEPER. Background and History Blue Ridge operates a bleached papergrade kraft pulp and paper mill in Canton,NC, which it purchased from Champion International Corporation in May 1999. Operations at the mill began in 1908, but the mill has been extensively modernized, most recently in 1993. The mill currently operates an 800 tpd hardwood pulping line and a 600 tpd softwood pulping line. After cooking, pulp from each line is further delignified in single-stage oxygen delignification systems installed in 1993. Hardwood pulp is subsequently bleached with a DEoD sequence pine pulp is bleached with a DEopD sequence. Target brightness is 85 ISO. Up to 80 percent of the filtrate flow from the pine bleach line is returned to the recovery cycle using the unique bleach filtrate recovery (BFRTM)process, developed by Champion. A portion of the hardwood line bleach plant Eo- stage filtrate flow is also recovered. Blue Ridge produces 250,000 tons per year of uncoated paper including offset, tablet and envelope grades. The mill also produces 281,000 tons per year of bleached paperboard used for liquid packaging and paper cups, including FDA approved grades for milk and juice cartons. Since November 2000,pulp production has been reduced by approximately 30 percent as the result of a major project to upgrade the No. 19 bleached paperboard machine. Continued Color Reduction Opportunities Since the 1997 NPDES Permit The Canton Mill's 1997 NPDES permit included a schedule requiring continued study, evaluation, and pursuit of effluent color reduction opportunities. Champion and Blue Ridge submitted a series of reports to the NC Department of Environment and Natural Resources, Division of Water Quality, evaluating the performance of the BFRTM process, end-of-pipe color reduction technologies, and practices for minimizing color losses from manufacturing processes. Since 1997 Blue Ridge has: • continued full-scale operation of BFR for the pine line; • concluded that full-scale BFR is not feasible for the hardwood line,but implemented partial reuse of a portion of the Eo-stage filtrate as an effective color-reduction approach; • identified and implemented several practices for reducing losses of highly-colored black liquor from manufacturing processes; and Page 3 • evaluated 16 end-of-pipe color removal technologies and detennined that they were presently economically and/or technically infeasible for the Canton mill. Process Improvements Analyzed by the Tech Team The Tech Team identified five mill improvements capable of further reducing the discharge of Lug 1r color in the mill effluent. For each of these improvements,technical feasibility, capital and operating costs, and potential color reduction were reviewed. Each improvement can be implemented independently of the others or in any combination. The costs incurred to ' implement the improvements are additive, however separate evaluations are necessary to accurately estimate the associated color reduction achieved by implementing any combination of improvements. End-of-pipe color treatment technologies (e.g., chemically assisted clarification with sludge dewatering and disposal) typically require initial capital investment and ongoing operating expenses, not savings, and are likely to incur non-water quality environmental impacts. For this reason, the Tech Team focused on pollution prevention approaches that offer the potential to be more cost-effective: color reduction in low flow, highly color-concentrated wastestreams,through manufacturing process changes or in-process treatment. The first two process improvements, discussed below (improvements in BFR reliability and leak and spill prevention and control - Best Management Practices (BMPs)), are improvements which the Tech Team concludes offer the highest certainty for technical feasibility and color reduction. Blue Ridge also identified these technologies as feasible color reduction opportunities that will be implemented, but differed from the color reduction estimates included in this memorandum. The next two process improvements (ozone addition to an existing chlorine dioxide bleaching stage on the hardwood fiber line; adding a second stage to the current oxygen delignification system on the softwood fiber line) also were evaluated by Liebergott, et. al., as feasible color reduction opportunities. Additional technical evaluation and/or laboratory testing would be appropriate to reliably determine the technical details of how to incorporate these processes into the existing fiber lines and to more accurately predict their achievable color reduction, and the relationship of these technologies to BFR. Additional analyses would be appropriate to determine the most cost-effective design and the most economically feasible schedule for implementing one or both of these improvements. The fifth process improvement, color treatment for the chloride removal process (CRP) purge stream (one of the two key components of the BFR process), has the potential for additional Page 4 color reduction. However, based upon initial bench-scale treatability studies by Blue Ridge, further study of additional color treatment technologies is necessary. Process optimization on both the hardwood and softwood fiber lines, as recommended in the BEPER, is anticipated to provide additional color reduction and is identified as the sixth process improvement. It was concluded that the process optimization option was among those with the highest certainty for technical feasibility and color reduction. All color reductions resulting from the mill improvements are estimates based solely on available data and information. While the Tech Team has concluded that these technologies would reduce the color discharge from the Canton mill, there is a lack of directly comparable operating �� experience with these technologies in other bleached a er rade kraft mills that can be used to RZy P g� P P g develop precise predictions of the extent of the color reduction benefits. The BEPER evaluated additional in-process technology options for color discharge reduction potential, including the implementation of a hot pressurized peroxide-enhanced extraction stage in both fiber line bleach plants. At this time, the Tech Team does not have sufficient information to confirm the applicability of this technology at the Canton mill nor relevant data to predict its potential color discharge reduction capabilities. Therefore, while this memorandum does not address this technology option, it may be feasible for implementation by Blue Ridge and contribute to reducing color. In addition,the Tech Team did not analyze nor did the BEPER recommend a Totally Chlorine-Free (TCF) bleaching option because of the high cost of this technology and the lack of experience in producing and successfully marketing products made by Blue Ridge at the Canton mill. 1. BFR reliability improvement. One of the two key elements in BFR is the Metals Removal Process(MRP). Blue Ridge has found that this process element has been more challenging and expensive to maintain than originally planned. The target BFR recycle rate (percent closure) for the pine line is 80 percent. Due to unforeseen equipment failures (e.g., ion exchange media) and metallurgy problems(e.g., erosion of multi-media filtration tank lining) in the MRP, however, the pine line closure has averaged only 74 percent from October 1998 to the present. Blue Ridge has undertaken improvements to the MRP system in order to maintain the process closure rate and increase operating time. Improvements include rebuilding piping and valves, and changing construction materials and metallurgy to better withstand the chemical and physical stress experienced in the BFR system. Blue Ridge estimates that if BFR closure is maintained at 80 percent, annual average final effluent color discharge will be reduced by 1,000 to 1,2001bs/ Page 5 At this time,the Tech Team has no means of making an alternative quantitative prediction of final effluent color reduction to compare to the Blue Ridge estimate. 2. Improved black liquor leak& spill collection and control (BMPs). The Canton mill has an extensive spill recovery system. Sumps in this system, including one sump added in the court yard adjacent to the digester house as required by the 1997 Settlement Agreement, are equipped with pumps that are activated automatically when sensors detect wastewaters with high conductivity and color. High conductivity material is routed to the recovery system. Further improvements to the black liquor collection system include: • continuous improvement of operating practices so more leaks and spills are recovered rather than discharged to sewer; • further improvement in preparation for planned outages to maximize capture of tank clean-out waste and routing to recovery; • further reducing clean water that continuously runs into sewers to prevent dilution of smaller spills and facilitate recovery of highly colored wastewaters; and • further improvement in the equipment used for handling of knots rejects to prevent black liquor leaks into the recovery sumps. The plot below shows the color of wastewater treatment influent at the Canton mill. The variability of influent color discharge to wastewater treatment is attributed to color discharge peaks that represent, in part,unplanned spills or leaks discharged to sewers or intentional diversions of highly-colored black liquor or other color sources routed to sewers during mill equipment shutdowns. kg/t Figure 1 75 Daily color at influent to W W TP for Canton so 25 L0 30 60 90 120 150 180 Page 6 Due to the nature of the manufacturing processes and practical equipment operation and reliability, all spills and color losses to sewers cannot be fully anticipated, predicted, and completely contained. However, a comparison of the variability of the Canton mill influent color data to available primary influent color data at another bleached papergrade kraft mill indicate that a detailed review of the spill prevention and recovery system at the Canton mill (by mill staff or external consultants), including involvement by the mill operators, can further uncover the causes of and better quantify black liquor losses and other color sources that can be avoided or recovered. This will result in an overall reduction in color discharge, both in long-term average and variability. Through improved planning of mill equipment shutdowns;continuing �p aj efforts to minimize process operation variability, and increased recovery of highly-colored leaks and spills, discharges of highly colored material to the wastewater treatment system can be ' reduced more consistently below existing levels. Further reducing peaks in color discharges within the mill and preventing highly colored flows from reaching the wastewater treatment system will further reduce the variability of color discharges from the wastewater treatment system to the Pigeon River. For example, limiting the color of the primary clarifier influent to less than 70,000 lb/day through continuing efforts to improve the mill's 8MP system and process operations would reduce the color loadings from mill processes to the end-of-pipe wastewater treatment system by more than P,000 IbIdayl The Canton mill operated under this primary clarifier influent color threshold approximately 74 percent of 2000, excluding November through December 2000. This time period Enconsidered not to be representative of steady-state operations because of the reduced pulp production resulting from upgrading the No. 19 bleached paperboard machine. Assuming the average reduction of 45 percent across this"wastewater treatment system for"brown" color derived from black liquor, this would result in a minimum decrease o ,4001b/da in the average final effluent color load. AO-J ) � __�41 �`�� 0/�' \ Clean water, such as packing gland water, presently flows in several sewers with recovery sumps. These colorless streams dilute other colored wastestreams, such as small black liquor leaks and spills, to the point where the in-stream conductivity is too low to trigger recovery. By eliminating clean water streams or diverting them away from sewers that collect black liquor leaks and spills, wastewater streams with elevated color can be recovered more readily,resulting in a reduction in color discharge to the end-of-pipe wastewater treatment system. Also, the unintentional but intermittent discharge to the sewer of filtrate from knots and screen rejects can be recovered. Page 7 At this time, the Tech Team has no basis for determining an accurate correlation between unaccounted color and sewer generated color, as reported in Section 2 of the Canton Mill Environmental Performance Update presented by Blue Ridge during the March 14,2001 Tech Team Canton mill visit. During the March 14 visit, Blue Ridge staff indicated that results of studies of sewer generated color showed a relationship between bleach plant filtrate pH and temperature and unaccounted color generated in mill sewers. By operating within the range of pH and temperatures identified during the studies the Canton mill has had some success in controlling this source of unaccounted color. Based on this information, the Tech Team concludes that by further reducing process operation variability, including operating within the, pH and temperature range identified during the studies,the mill can continue to also minimize , sewer generated color,thereby reducing one source of unaccounted color. Reducing overall color discharges through BMPs and other management practices will likely further reduce remaining unaccounted color. However, additional studies are necessary to further develop any relationship between accounted and unaccounted color sources. — As noted above, analysis of primary clarifier influent color loading data demonstrates that color loading to the wastewater treatment system of lower than 70,000 lbs/day is possible during steady-state operations. Through continuing efforts to minimize unplanned spills and leaks and intentional discharges of colored streams and continuing efforts to minimize process operation variability,the Canton mill can achieve fiirther reduced primary clarifier influent color loads and subsequent final effluent color discharge within this range on a more consistent basis than demonstrated in 2000 (i.e., more than 74 percent of the time). On this basis,the Tech Team concluded it is feasible to reduce final effluent color by more than 5,000 lbs/ ay through improved black liquor leak and spill collection and control. 3. Ozone/Chlorine dioxide stage for hardwood bleach line. Ozone is used in more than ten kraft mills around the world to bleach pulp, including two in the US and one in Canada. There are several process configurations, but the most common is to operate an ozone (Z)mixer and reactor immediately upstream of a chlorine dioxide reactor, without any washing between the application of the two chemicals. This is known as a"ZD" stage. A system of this type was retrofitted in the Domtar mill at Espanola, Ontario, Canada in 1999? Bleachin with ne on the hardwood line, one of the Domtar mill's two pulp lines, resulted in a 7 percent r duction in f�°�',�;"/� the discharge of color in the combined mill treated effluent.' The conversion to a ZD stage 2 Munro,Fred and John Griffiths,Operating Experience with an Ozone-based ECF Bleaching Sequence,Tappi,2000. �w 3 Ibid. Page 8 would reduce the use of chlorine dioxide and caustic chemicals for bleaching in exchange for ozone. The energy requirements for ozone production would be offset by the energy savings from less chlorine dioxide and caustic production,resulting in a net reduction in energy consumption with the ZD stage. As of September 2000, the long-term average color discharge from Canton's hardwood bleach line was 12,800 pounds/day'. The Espanola experience suggests that implementation of a ZD stage in the hardwood bleach plant at the Canton mill could reduce the filtrate color discharge by 3,000 to 6,400 lbs/day. Based on comments received, the Tech Team acknowledges that operating parameters, such as wood species processed and technology supplier performance guarantees, may influence the practical color reduction achievable through implementation of a ZD stage at the Canton mill, in comparison to the Espanola experience. These estimates are based solely on the demonstrated performance and the Tech Team's assumption of color sources at the Espanola mill, confirmed at the recent Pulp and Paper Technical Association of Canada (PAPTAC)meeting in Thunder Bay, Ontario. Laboratory bleaching trials and possible communication between Blue Ridge and Domtar staff would be necessary to reliably predict the achievable color reduction possible with this option for the Canton mill. �FR r The technical evaluation of this process improvement included in the BEPER yielded a hardwood filtrate color discharge reduction within the range of Tech Team estimates. 4. 2"d stage OD for pine line. Oxygen delignification(OD) on the Canton Mill pine line is a single stage system installed in 1993. It has been concluded that retrofitting a second OD stage for the pine line could contribute to reduced color discharges in two ways. The first would be a reduction in color for those filtrates presently not captured and reused in the BFR process. The second would be a color reduction in the Chloride Removal Process (CRP)purge stream as a result of less chloride from chlorine dioxide used for bleaching. Costs were estimated for a reactor with oxygen mixer and chemical charge equipment installed upstream of the existing reactor. Previously,the Tech Team anticipated increasing the kappa number(lignin content) of the cooked pulp from 24 to 32 and utilizing a two-stage OD system to reduce kappa number from 32 to 11, an approximate 65 percent kappa reduction across the two- stage system. Based upon comments from BRP and further technical analysis, and review of the BEPER, it was concluded that it is technically feasible for a two-stage OD system at the Canton 4 Jacobs Engineering Group,2001 Color Removal Technology Assessment,February 2001. Page 9 mill to achieve an overall reduction of 50 percent in kappa number, rather than 65 percent as previously anticipated. Therefore, with the Canton mill continuing to pulp to a kappa number of 24,the new two-stage OD system would reduce pulp kappa number into the bleach plant from the current output of 16 to about 12, corresponding to a 50 percent kappa number reduction from the current digester output of 24. The quantity of color released from the bleach plant will be reduced in proportion to the reduction of the input kappa number. By decreasing the kappa number of the pulp fed to the bleach plant from kappa 16 to 12 with a two-stage OD system, the quantity of chemicals required in the first two stages of the bleach plant can be reduced, because there is less lignin present in the incoming pulp to remove by bleaching. The reduction in chlorine dioxide used for bleaching would result in a proportional reduction in chloride load to the CRP and reduce color discharged from the purge stream in proportion to the reduction in chloride being treated. In response to comments received, it has been concluded that implementing a two-stage OD system without increasing the kappa number of the cooked pulp from 24 to 32 would not achieve a 1.5 percent pulp yield gain as anticipated with increasing digester kappa number and achieving greater delignification with the proposed two-stage OD system. However, operating a two-stage OD system with a higher than 50 percent delignification rate and a digester kappa number higher than currently employed at the Canton mill is commonly seen at comparable bleached papergrade kraft mills. Therefore,the Tech Team anticipates that additional process engineering will maximize the benefits of a two-stage OD system at the Canton mill and enable the mill to capture the increased delignifcation and yield gain potential of this technology and achieve annual wood cost savings of up to approximate $950,000 from up to a 1.5 percent yield increase across the proposed two-stage OD system. Based on additional information supplied by Blue Ridge regarding operational limitations of the BFR system, the Tech Team concludes that a two-stage OD system would not have a significant impact at this time on the Canton mill's ability to increase BFR closure rate above 80 percent on a day-to-day basis. For this analysis, it was estimated preliminarily that a second OD stage could reduce total influent color discharge to the wastewater treatment system by 1,500 to 2,000 lb/day from reductions in pine line bleach plant filtrate color and CRP purge stream color. Page 10 The technical evaluation of two-stage OD included in the BEPER yielded reduction in color discharge influent to the wastewater treatment system within the range of the Tech Team estimates. 5. Color Treatment of CRP purge stream. The Chloride Removal Process (CRP) purge is a low flow, highly concentrated waste stream. Color is typically 50,000 pen, in a 10 gpm(0.01 MGD) flow. The CRP purge contributes up to approximately 5,000 lbs/day (13 percent) to the total mill loading to the wastewater treatment system influent, but only 0.06 percent of the discharge flow. It was originally speculated that it may be feasible to reduce the color in this stream by precipitating the colored organic material with lime at a dosage of 20 g/L5, and burning the resulting sludge with the main lime mud stream fed to the mill's lime kiln. Laboratory trials would be necessary to test the feasibility of color removal from the CRP purge stream by lime treatment. Blue Ridge subsequently conducted laboratory trials of color precipitation using four calcium compounds, including lime mud, fresh lime, calcium chloride, and milk of lime. The preliminary results of these trials show that at a dosage of 20 g/L, none of the compounds tested reduced color in the CRP purge stream. Although color removal was demonstrated at higher dosage rates, increased chemical usage would result in substantially higher operating costs, require larger sized equipment at higher capital cost, and also result in a higher production rate of sludge to be burned in the mill's lime kiln. Excess sludge produced from this process that is not burned must be landfrlled at additional cost. Based on preliminary laboratory trials,Blue Ridge concluded that lime treatment of the CRP purge is not a feasible color reduction option for the Canton mill. However, the Tech Team recommends additional review of other innovative technologies for treatment of color in the CRP purge stream, such as the application of the X-Filter process recently implemented at a totally chlorine free(TCF) mi116. By minimizing color contributions from this stream, the potential exists to achieve a significant reduction in primary influent color discharge of up to 5,000 lbs/day. 5 NCASI Technical Bulleting No.239,The Mechanisms of Color Removal in the Treatment of Pulping and Bleaching Effluents with Lime.I.

The BEPER identified sixteen recommendations for optimizing the hardwood and softwood fiber lines, focusing mainly on the current OD systems and bleaching operations. It was estimated that a reduction could be achieved in chlorine dioxide use in the first bleaching stage of up to 27 percent for the hardwood line and 18 percent for the softwood line. The reduction in chlorine dioxide use would result in a bleach plant filtrate color reduction of up to 700 lbs/day from the hardwood line and up to 400 lbs/day from the softwood line. The Tech Team estimated an additional color reduction from the CRP purge stream of 6001bs/day resulting from the decreased chlorine dioxide usage. At this time,the Tech Team has no means of making an alternative quantitative prediction of bleach filtrate color reduction to compare to estimates presented in the BEPER. Therefore, it is estimated that through efforts by mill staff to maximize the color reduction benefits from the process optimization opportunities identified by Liebergott, et, al., the Canton mill would achieve a total color reduction of 1,7001bs/day in wastewater treatment system influent. Color Reduction Summary The Tech Team estimates that by improving BFR reliability and black liquor leak and spill collection and control, the Canton mill final effluent will be reduced by more than 5,000 lbs/day. Process optimization, as outlined in the BEPER, would result in a further final effluent color reduction of approximately 1,400 lbs/day. This assumes the average color reduction of 45 percent across the existing wastewater treatment for the CRP purge stream and other"brown" color sources derived from black liquor and no reduction in color from bleach plant filtrates. Table 1 presents asummary of the estimated reductions in final effluent color attainable with the highest certainty by implementing improved BFR reliability, improved BMPs, and process optimization.

These process improvements require further study to more accurately determine achievable color reduction and thus are not recommended at this time for immediate implementation. These improvements include a ZD stage in the hardwood bleach plant, with a preliminary estimate of a 3,000 to 6,400 lbs/day color load reduction in influent to the wastewater treatment system, and a second OD stage for the pine line, with a preliminary estimate of a 1,500 to 2,000 lb/day color load reduction in influent to the wastewater treatment system. Table 2 presents a summary of preliminary estimates of color reductions for these two additional process improvements that need further study. Reductions presented in Table 2 are preliminary estimates with reduced certainty compared to those presented in Table 1, but are based upon identified technology options available for the Canton mill.

Blue Ridge Paper Products is owned 55 percent by KPS Special Situations Fund,L.P. and 45 percent by the employees of Blue Ridge Paper through an employee stock ownership plan. At the time of the 1997 report EPA documented substantial losses over five years for the Canton Mill and Champion had just announced its intention to sell or close the mill. However,because of the sale of the mill to the Blue Ridge, the previous data are not comparable to the more recent data. Further,the data submitted by Blue Ridge is still confidential, so this report cannot present as much detail as the 1997 report. The current analysis is based on information submitted by Blue Ridge covering part of 1999 (May-December) and all of 2000 (all of the existing financial data for the company). The results may be relatively uncertain because of the lack of data and the company may be too young for the current data to reflect its ultimate financial health. EPA used three measures of financial health (gross profit test, discounted cash flow, and Altman's Z)7 to assess the impact of 7 See Interim Economic Guidance for Water Quality Standards: Workbook,EPA 823-B-95-002,March 1995,and Economic Analysis for the National Emission Standards for Hazardous Air Pollutants for Source Category: Pulp and Paper Production; Effluent Limitations Guidelines,Pretrpatment Standards,and New Source Performance Standards:Pulp,Paper, and Paperboard Category—Phase 1.

The NPDES permit will expire on November 30, 2001 and the application for renewal was received on February 23, 2001. This fact sheet summarizes the rationale used to develop the North Carolina Division of Water Quality's recommendations for the draft permit. BACKGROUND Blue Ridge Paper is an employee-owned and operated integrated, elemental chlorine free (ECF) bleached kraft pulp with oxygen deligninifcation and bleach filtrate recycle, and paper mill in Canton, North Carolina. Processes at the mill include a pine bleach line; hardwood-bleach line, paperboard and fine paper production lines. Pine and hardwood chips are transported to the site via rail or truck and subsequently processed into pulp for paper or paperboard production. In or around 1990, Champion International Corporation (Champion Paper- now Blue Ridge Paper) initiated a $300 million dollar modernization project termed the Canton Modernization Project. This project eliminated the use of elemental chlorine and implemented significant changes to-both the pine and hardwood bleaching lines. The mill upgrade included two changes that dramatically improved the mill's environmental impact. The first major change was the use of oxygen delignifrcation. This process is used to separate the lignin from the fiber. This resulted in significant improvement in the mills environmental performance. The second major change was the implementation of full-scale bleach filtrate recycle (BFR) on the pine bleach line and caustic extration stage (E.) filtrate recycle (-20%) on the hardwood bleach line. For a Fact Sheet NPDES Renewal Page 1 more detailed description of the mill improvements, refer to the Canton Modernization Project Section below. The Canton Modernization Project greatly reduced the wastewater generated and eventually discharged to the Pigeon River. Even with these improvements, significant quantities of wastewater are generated in the production of pulp and paper and proper treatment prior to discharge is required. Wastewater generated by the Canton Mill, along with the Town of Canton's domestic wastewater, is treated at Blue Ridge Paper's Wastewater Treatment Plant. The treatment plant is a 29.9 MGD wastewater treatment system consisting of the following unit processes: • Grit Chamber • Bar screens • Lift pumps • Polymer addition pH control (CO2 injection or H2SO4 backup) • Three primary clarifiers (one normally off-line) • Nutrient feed • Aeration basins • Three secondary clarifiers • Residual belt presses • Effluent flow measurement • Cascade aeration (with oxygen injection) • Oxygen injection facilities Solids at this facility are deposited into a dedicated landfill. The history of this mill, under the ownership of Champion Paper and now Blue Ridge Paper, has been controversial. Under Champion Paper, the environmental impacts of the Canton Mill were noted by concerned citizens, environmental groups, the State of Tennessee, State of North Carolina, and the United States Environmental Protection Agency (EPA). The issues raised by these individuals and groups contributed to the Canton Mill's improved environmental performance and resulted in a settlement agreement issued January 8, 1998. Today the relationship among the various stakeholders has evolved to one of cooperation. The Division commends all the groups for their willingness to work together to improve water quality. This permit has centered around four main issues emanating from the mill's discharge: color, temperature, oxygen consuming waste and dioxin, and a.brief synopsis follows. Color On July 13, 1988, Champion Paper was granted a variance from North Carolina's narrative water quality standard for color, which the EPA interpreted to be 50 color units. The EPA subsequently issued a NPDES permit to Champion Paper facility in Canton, North Carolina. In 1994, the EPA returned NPDES permitting authority for the Canton Mill back to North Carolina's Division of Water Quality. During the permit renewal the original color variance was modified and both were issued around December 11-12, 1996. As outlined above, over the course of this variance the mill has initiated significant improvements, which have dramatically reduced the color loading and other effluent characteristics. Though the mill has made tremendous strides, color continues to be the focal point surrounding this permit. The EPA chaired Technology Review Workgroup have recommended additional color reduction for the up coming permit cycle. The recommendations issued by the Technology Review Workgroup included the findings of a third party evaluation of Blue Ridge Paper's Canton mill and the. "report issued by the EPA Tech Team . The evaluation conducted by Dr. Norm Liebergott was co- sponsored by Blue Ridge Paper and several environmental groups and provided valuable information for the TRW'. In addition, to identifying areas for improvement and available technologies, Dr. Liebergott compared the Canton mill to similar mills around the world. Dr. Liebergott concluded that the Canton mill's environmental performance is among the best in the world. Though incredible work has been done, there continues to be a need to reduce color further. Blue Ridge Paper's openness and willingness to work towards continued improvements has resulted in an atmosphere of trust and cooperation among all the interested parties. This cooperation has been extremely valuable and will continue to be critical as the additional color reductions recommended by the Technology Review Workgroup are implemented (see attached July 24, 2001„memo from the EPA Tech Team to the Technology Review Workgroup). Fact Sheet NPDES Renewal Page 2 The Technology Review Workgroup report identifies process improvements that will result in permitted color reductions of 6,000 pounds per day. In addition, the report identifies process improvements that will require further study but are likely to result in total color reductions in the range of 9,000 - 14,000 pounds per day. The mill will also evaluate the feasibility of treating the highly colored low flow wastestream from the chloride removal process (CRP). The feasibility of additional color reductions associated with the treatment of the CRP wastestream is highly uncertain and no color reductions have been established for this permit cycle. The result of a feasibility study on the Chloride Removal Process wastestream will be evaluated for possible additional color reductions for the next permit cycle. As shown in Table 1, the 6,000 pound per day annual average color reduction will become effective on December 1, 2003. Additionally, the mill will evaluate additional process improvements in order to achieve an annual average effluent color loading of 34,000 - 39,000 pounds per day. If the limits determined to be achievable are within the target range,the limits shall become effective on December 1, 2005, by written notification from the Director. In the event that the achievable limits are outside of this range then the NPDES will be reopened. At that time, public comments will be gathered and the permit may be modified. Table 1.

This determination demonstrated that the effluent limitations relating to the thermal component of the Champion discharge were more stringent than necessary to assure protection and propagation of a balanced indigenous population of shellfish, fish, and wildlife in the Pigeon River. Therefore, the 316(a) determination was approved based on protection of the appropriate use classification of the Pigeon River. The temperature variance was reviewed and renewed as part of the Triennial Review in 1997. Blue Ridge Paper submitted a Balance and Indigenous Species Study on the Pigeon River on June 1, 2001. DWQ scientist have reviewed the report and concluded that continuance of the temperature variance is appropriate. Therefore, the Division of Water Quality is recommending continuation of the temperature variance with reporting requirements consistent with the previous permits (see Table 1). Oxygen Consuming Waste An EPA approved model predicted that even with a BOD5' loading of 1209 lb/day (5.0 mg/L at 29 MGD) that the dissolved oxygen in the Pigeon River would not be protected. Since Blue Ridge Paper cannot comply with such stringent limitations, an instream method was implemented to protect the dissolved oxygen in the receiving stream. For further discussion on this subject refer to the conventional pollutant section below. Dioxins Elevated levels of dioxins were found in fish tissue in the Pigeon River (around the late 1980s). Subsequently, a fish consumption advisory was issued for sport fish, catfish and carp. The Canton Mill has not discharged any detectable levels of 2,3,7,8 TCDD to the Pigeon River (since 1989) and dioxin in fish tissue continue to decline. Currently, a fish consumption advisory continues for carp and catfish. North Carolina has lifted the advisory on sport fish. However, the State of Tennessee continues to post a precautionary fish consumption advisory for carp, catfish and red breasted sunfish. BOD5 is an analytical method used to estimate the biochemical oxygen demand. Fact Sheet NPDES Renewal Page 3 The fish consumption advisories in North Carolina and Tennessee are currently under review for possible modification of the advisories. The North Carolina Division of Environmental Health (DEH) has initiated a review of the fish consumption advisory on Pigeon River and Waterville Lake. DEH is evaluating dropping the advisory on catfish in the North Carolina portion of the Pigeon River and limiting the advisory on Carp to Waterville Lake. A final determination may not be finalized prior to permit renewal, therefore, recommendations presented in this permit do not reflect this evaluation. STREAM CONDITIONS The facility discharges to the Pigeon River near Canton, North Carolina. The Pigeon River from Canton to Hurricane Creek is listed as an impaired water, according to North Carolina's 2000 Draft 303(d) List, due to a fish consumption advisory for dioxins. Recent data indicate that the dioxin levels in fish tissue continue to decline. There has been no detection of 2,3,7,8 TCDD in sport fish since 1995 and below North Carolina's fish consumption advisory level for 2,3,7,8 TCDD in catfish since 1997, based on Blue Ridge Paper's data. 2,3,7,8 TCDD continues to be detected in carp, though levels continue to decline and are below North Carolina's advisory level. The Pigeon River has been experiencing extremely low flows; due to extended drought conditions in the western part of the state, with flows often less than the 7Q1O flows of 52 cfs (near Canton). Curtis Weaver, with the USGS, provided the updated low flow statistics noted above using data from 1933 through 1999. The low flow statistics at Canton include the influence of Lake Logan, which was constructed in 1932 and the influence of both Lake Logan and Lake Junaluska (constructed in 1913). This reflects the current hydrography within the watershed and does not reflect conditions prior to construction of the lakes. The impact of this reevaluation of the low flow statistics is that the lowest seven day average flow expected once in ten years (7Q10) has been reduced from 54 cfs to 52 cfs. This affects the instream waste concentration which is used to determine the limits for the toxicity testing (discussed later). INSTREAM MONITORING The current permit requires Blue Ridge Paper to conduct an extensive instream monitoring program consisting of 12 monitoring sites (1-upstream of mill in Pigeon River, 3-Waterville Reservoir, and 7- downstream of mill in Pigeon River and 1-Big Creek; See Figure 1 and Table 2). Instream Monitoring by Parameter Blue Ridge Paper is required to monitor fecal coliform upstream (at station UP) and downstream of the discharge (at station DNI). Analysis indicates no discernable difference between the upstream and downstream fecal coliform levels. Upstream fecal coliform is generally in the range of 100 to 200 /100m1. The same trend is evident at the downstream sampling point. These data suggest that Blue Ridge Paper does not contribute significant levels of fecal coliform. Monitoring of the effluent is sufficient to monitor the mill's impact on the river. Blue Ridge Paper has volunteered to conduct upstream sampling and this requirement will remain as a condition in the permit. Thus, the Division's recommendation is the elimination of the downstream fecal monitoring and once per week fecal monitoring upstream. Blue Ridge Paper is required to monitor conductivity upstream (at station UP) and downstream (at station DN1). There is a significant increase in conductivity between the upstream and downstream monitoring sites. Conductivity measurements are less than 50 umhos/cmZ at the upstream monitoring station and generally greater than 250 umhos/cm2 at the Fiberville Bridge. This increase in conductivity is expected since conductivity is a measure of inorganic material. Thus, the Division's recommends that conductivity monitoring continue as required by 15A NCAC 2B .0508(d). Fact Sheet NPDES Renewal Page 4 Figure 1.

Levels of BOD5 have been less than 2.0 mg/L. Based on this information and the Division's lack of need for the data, it is recommended that instream BOD5 monitoring be eliminated from the permit.

Comparing upstream to downstream, see Figure 2, the temperature difference ranged from between 1.78 °C and 11.65 °C. At no time did the monthly average temperature of the Pigeon River exceed the permitted limits of 32 °C (summer) or 29 °C (winter). Blue Ridge Paper monitors dissolved oxygen (DO) at all the instream stations except station DN6 and station BC. Over the period of review (1998 —2000), dissolved oxygen did not drop below the North Carolina's standard of 5.0 mg/L for Class C streams at any of the instream monitoring locations. Figure 3 summarizes the results of this analysis. During the previous permit cycle, an EPA-approved computer model indicated that BOD5 limits were required to protect North Carolina's instream dissolved oxygen standard of 5 mg/L for Class C waters. An economically feasible end-of-pipe technology capable of consistently treating to levels necessary to meet the limits specified by the model did not exist. North Carolina agreed with the continuation of the requirement that Blue Ridge Paper meet the instream dissolved oxygen standard by use of sidestream oxygen injection facilities. Blue Ridge Paper maintained these oxygen injection facilities at the effluent and at approximately 0.9, 2.1, and 3.7 miles downstream of the discharge. The previous NPDES permit required Blue Ridge Paper to maintain the oxygen injection facilities located 0.9 and 2.1 miles downstream. To ensure compliance with the above requirement, the average daily instream dissolved oxygen levels at stations DNl, DN2 and DN3 were required to equal or exceed 5.0 mg/L and the minimum instantaneous instream values were required to be greater than or equal to 4.0 mg/l. If dissolved oxygen drops below the prescribed values Blue Ridge Paper shall utilize the instream dissolved oxygen injection stations to increase the dissolved oxygen in the river. Fact Sheet NPDES Renewal Page 6 This method fulfilled the requirements of 40 CFR 125.3 (f). Blue Ridge Paper has compiled an extensive database on instream dissolved oxygen concentrations and stream flow. These data suggest that the dissolved oxygen sag occurs at station DN2. Figure 2.

The Town of Clyde has recently removed their discharge and the Division has received a letter from the Town requesting rescission of the permit. Based on a review of the instream data and the removal of Clyde's discharge, it is recommended that the dissolved oxygen compliance point at station DN3 be eliminated. The Division reviewed the 1998 through 2000 instream dissolved oxygen data. Over this time period, Canton, North Carolina has experienced extreme drought conditions and flow in the Pigeon River has often dropped below the updated 7Q10 stream flow. Under these conditions, the lowest dissolved oxygen level observed in the North Carolina portion of the Pigeon River was 5.0 mg/L and occurred at river mile 57.7. Additionally, a review of the average daily instream dissolved oxygen data and the average over this time period indicates that the dissolved oxygen sag occurs at river mile 57.7. Based on this analysis, the compliance point and monitoring requirement at river mile 55.5 have been dropped. The oxygen injection facilities will continue to be maintained at the effluent, 0.9, and 2.1 miles downstream, and used as necessary to maintain an instream dissolved oxygen level of 5 mg/l. The condition to maintain the instream dissolved oxygen stations shall remain a condition of the permit until such time that the permitted loading of oxygen consuming waste to the Pigeon River is less than or equal to that proposed by an appropriate water quality model. If dissolved oxygen at station 57.7 drops below 5.0 mg/L, the facility is required to monitor dissolved oxygen at river mile 55.5 and 53.5. Instream monitoring continues to be required in order to assess Blue Ridge Paper 's impact on the Pigeon River and to ensure that the dissolved oxygen standard is maintained within the river. COLOR The 1997 Settlement Agreement contained provisions to limit color in the Pigeon River at the Hepco USGS gauge station. The new effluent limits in this permit are more stringent than the provisions in the 1997 Permit and Color Variance and will result in reduced color levels in the Pigeon River. It is possible to calculate the monthly flow at the Canton gage station above which instream color at the Fiberville Bridge will not exceed 50 true color units. Using the 55,000 pounds per day monthly average true color loading limit(implemented on the effective date of the permit)the flow at the Canton Gage station,which will provide for color less than 50 true color units at the Fiberville Bridge is 171.8 MGD. Therefore,the monthly average color in the Pigeon River at the Fiberville Bridge will be less than 50 true color units whenever the monthly average flow(at the Canton gage station) is greater than 171.8 MGD. North Carolina is recommending that the Fiberville bridge be the basis for the color variance. The governing flow criterion for true color at Canton is 58.1 MGD (30Q2 stream flow). The flow established is greater than this 30Q2 stream flow,therefore,for flows less than the 171.8 MGD at the Canton Gage station but greater than 193.3 MGD at the Hepco gage station,the monthly average color in the Pigeon River at Hepco will be less than 50 true color units. Currently, the basis for the color variance is the Hepco station (DN5) within North Carolina, therefore with the moving of the station from Hepco to Fiberville, DWQ recommends that the mill monitor the Hepco station 2/week during the summer and once per week during the winter. During the permit cycle,the effluent color limit will be reduced,therefore,the instream color criteria will be adjusted accordingly. The monthly average color in the Pigeon River at the Fiberville Bridge will be less than 50 true color units whenever the flow at Canton is greater than the flow established using the following equation and based on the monthly average effluent limit established per Special Condition A.(8:)Paragraph 4: FlowatCanbnUSGS(MGD)_ (MonthlyAvarageEfflueztColorLiidt,W day—12468.3)+31.6+2.4 308.58 For flows at the Canton Gage station less than the flow established here but greater than 193.3 MGD at the Hepco gage station, the monthly average color in the Pigeon River at Hepco will be less than 50 true color units. Compliance Summary The facility has been in compliance with permit conditions during this cycle. Fact Sheet NPDES Renewal Page 8 Toxicity Testing Current Requirement: Chronic toxicity limit monitored quarterly @ 87% In December 1999 the facility reported a chronic level of 81% (with a state split sample greater than 87%), with the following two months greater than 100. All other toxicity tests over the past four years were greater than the stipulated 87%. The toxicity testing requirement is placed on all major facilities and other facilities with complex wastestreams. The toxicity limit is based on the instream waste concentration under 7Q10 conditions (52 cfs updated April 2001). For Blue Ridge Paper, the instream waste concentration was determined by also accounting for the out-take of surface water from the facility (31.6 MGD, as per application) and water withdrawal by the Town of Canton (allocated 6.8 MGD). Therefore, the instream waste concentration was determined to be 100% under 7Q10 conditions. The Division has set a ceiling on the toxicity test of 90%. This was done because of difficulties associated with averaging toxicity test with limits of 100%. The Division feels that 90% is sufficiently stringent to assess the chronic toxicity of an effluent, while allowing for the averaging of multiple tests. Recommended Requirement: Quarterly Chronic Toxicity @ 90% Mar, Jun, Sep, Dec Blue Ridge Paper is required to perform the NC Whole Effluent Toxicity Test or an equivalent method (as approved by the Division) on a quarterly basis at 90%. Any equivalent method shall also be performed on a quarterly basis. Toxicant Analysis Using the self-monitoring data required per the NPDES permit, reasonable potential analyses were conducted on the following toxicants: mercury, zinc, cadmium, selenium and silver. The standards used for the analyses are consistent with North Carolina standards for a class C waterbody. Cadmium—Based on the Division's analysis of self-monitoring data, this discharge does not pose a reasonable potential to cause a violation of the North Carolina stream standard for cadmium. Effluent monitoring of cadmium shall continue since cadmium continues to be detected in the effluent. Mercury — Based on the Division's analysis of self-monitoring data, this discharge does not pose a reasonable potential to cause a violation of the North Carolina stream standard for mercury. Additionally, all mercury samples analyzed since January 1999 have been below North Carolina's accepted detection level of 0.2 µg/L. Results from the Division's 1996 Fish Tissue Mercury Assessment on the Pigeon River indicate, "total mercury results were comparable to `background' levels expected for fish across North Carolina." Based on the findings in this report and the `Reasonable Potential' Analysis, it is recommended that mercury monitoring and limitation be removed from the permit. Silver -Based on the Division's analysis of self-monitoring data, this discharge does pose a reasonable potential to cause an exceedence of the North Carolina's Action Level Standard for silver. Numerical limits for silver are not being included since silver is an action level water quality standard and the biomonitoring requirements are adequate to control toxicity due to the presence of silver. Though no limit is proposed, if the facility experiences chronic toxicity violations, the discharge will be re- evaluated and a silver limit may be implemented according to the Division's Action Level Policy. Selenium—The Division's analysis indicates that the maximum predicted concentration for selenium is greater than the allowable concentration. This analysis included only seven data points, with six data points below the quantitation level. One sample indicated the presence of selenium, however the concentration reported was at the quantitation level for the method. Additionally, the QA/QC data questions the validity of this data point. However, the Division has limited Blue Ridge Paper for Selenium. After collecting for one and half years (six data points) of data, the facility can request that the Division review the Selenium data for possible elimination of the limit. Zinc- Based on the Division's analysis of self-monitoring data, this discharge does pose a reasonable potential to cause an exceedence of the North Carolina's Action Level Standard for zinc. Numerical limits for zinc are not being included since zinc is an action level water quality standard and the biomonitoring requirements are adequate to control toxicity due to the presence of zinc in the facility effluent. Though no limit is proposed, if the facility experiences chronic toxicity violations the discharge will be re-evaluated and a zinc limit may be implemented according to the Division's Action Level Policy. Monitoring requirements for zinc are consistent with 15A NCAC 2H .0508 (d). Fact Sheet NPDES Renewal Page 9 OXYGEN CONSUMING WASTE POLLUTANTS A site-specific Best Available Technology (BAT) based limit was calculated to determine the monthly average 5 - day biochemical oxygen demand (BODS) limit. A site-specific BAT approach was used because North Carolina's Division of Water Quality continues to agree that an economically feasible end-of-pipe technology capable of reliably meeting the water quality limit specified by the existing model does not exist at this time and no violations of the dissolved oxygen standard in the river have been observed in recent years. The North Carolina Division of Water Quality's recommendation for the draft permit BODS limit is established based on the demonstrated level of performance for the existing treatment plant. Data on treatment plant performance and influent loading from the Canton Mill (1998 through 2000) was evaluated and examined for outliers. As indicated in the "Bleach Environmental Process Evaluation and Report", the performance of this mill is among the best in the world. The maximum influent loading and lowest treatment plant performance were used to develop the monthly average BOD5 limit. The data set was sufficient to account for the day to day variability of the treatment system. Over the time period evaluated, the treatment plant has performed extremely well. The lowest percent removal was 96.9% and the highest influent loading was 414.9 mg/L. Based on this analysis, North Carolina's Division of Water Quality recommends a monthly average BOD5 loading of 3205.0 lbs/day. The limit presented in the draft permit represents and a 71-ton per year reduction in BOD5 loading to the Pigeon River. Because Blue Ridge Paper has oxygen injection facilities in place to maintain the instream dissolved oxygen standard should instream dissolved oxygen dictate a need, Blue Ridge Paper complies with the conditions set forth by 40 CFR 125.3 (f). The methodology used for the daily maximum 5 - day biochemical oxygen demand (SODS) limit was recommended during the previous permit cycle. A site-specific daily maximum to monthly average multiplier was used for determination of the recommended daily maximum limit. Using this methodology and reviewing data since the Canton Modernization Project (1998 —2/2001) the recommended daily maximum limit based on a multiplier of 3.4 (daily maximum/monthly average) is 10897 lb/day. The limit proposed represents an achievable level and approximately a 12.5% reduction in the daily maximum BOD5 limit. Ammonia monitoring requirements are included in the permit to provide data concerning levels of ammonia discharged to the Pigeon River (which may affect instream dissolved oxygen). Effluent dissolved oxygen is limited at no less than 6 mg/l based on the above discussion. Daily monitoring is required based on 15A NCAC 2B .0508 (d), Paper and Allied Products, Class IV facility. NUTRIENT POLLUTANT ANALYSIS Total phosphorus and total nitrogen monitoring is required by 15A NCAC 2b .0508 (d) (2) (A). Monthly monitoring is required to assess the contribution of nutrients from Blue Ridge Paper and the potential impact to Waterville Reservoir. Waterville Reservoir is to be monitored once annually (during opposite years of CP&L's montioring) to assist in the continued characterization of nutrient impacts to the lake. TOXICANTS There is currently a fish consumption advisory due to dioxin for the Pigeon River downstream of the discharge. Although the advisory was initially in effect for consumption of all fish species, this advisory has been reduced to carp and catfish species only, reflecting continued improvements in the river. Currently, Blue Ridge Paper is required to monitor dioxin and dibenzofuran isomers quarterly from the influent, sludge, landfill leachate, and effluent. Based on an evaluation of the data, the Division is recommending a revision to the special condition requiring dioxin and dibenzofuran isomers monitoring. An improved knowledge of the dioxin and dibenzofuran isomers indicates that only 2,3,7,8 TCDD and 2,3,7,8 TCDF are pollutants of concern. Therefore, it is recommended that the dioxin isomer special condition be modified to require monitoring only for 2,3,7,8 TCDD and 2,3,7,8 TCDF. Fact Sheet NPDES Renewal Page 10 It is further recommended that the monitoring frequencies be modified based on the fact that measurable quantities of dioxins and dioxin isomers have not been detected in the influent (since 1997), the effluent (since 1996), sludge (since 1996) and the landfill leachate (since 1996). The effluent limit for 2,3,7,8 TCDD has been reduced. During North Carolina's development of the Total Maximum Daily Load for Dioxins on the Pigeon River, the EPA commented that the chronic standard adopted by North Carolina should be applied as an effluent limit at the end of pipe. North Carolina did not agree with this methodology, since it is inconsistent with the standard and North Carolina rules. In addition, the management strategy implemented by North Carolina to address dioxins in the Pigeon River for several years and the data show that this management strategy is resulting in declining dioxin levels in the Pigeon River. The EPA, NC DWQ and Blue Ridge Paper agreed that the TMDL requirement could be waived as long as Blue Ridge Paper's effluent was limited at 0.014 pg/L. Therefore, the dioxin limit has been reduced to 0.014 pg/L and no TMDL will be developed. Annual fish tissue analysis shall continue to be performed by the facility in accordance with the monitoring plan approved by the Division until such time that the fish advisory is lifted in both Tennessee and North Carolina, according to North Carolina's delisting procedures. Trichlorophenol/Pentachlorophenoi limits and monitoring are not required. The permittee has certified that chlorophenolic biocides are not used at the facility. This certification eliminates the requirement to include effluent limits for these two parameters based on 40 CFR 430. However, if the facility changes future operations to include chlorophenolic biocides, limits and monitoring will be required. OTHER POLLUTANTS OF CONCERN The total suspended solids (TSS) limits were calculated using the EPA promulgated Effluent Guidelines for the Pulp, Paper, and Paperboard Point Source Category and compared to existing limits. The TSS limits contained in the current NPDES permit are more stringent than the calculated federal effluent guidelines since the current limits are based on the 1993 proposed guidelines for the oxygen deligni£ication process. The Division recommends that the existing TSS limits remain unchanged for this permit cycle. North Carolina does not have a numeric standard for TSS. The rules specifically regulate floating solids, settleable solids, and sludge deposits [ref. 15A NCAC 2B .0211(3)(c)]. The draft permit restricts floating solids. Both benthic and IBI studies have indicated further improvement to the Pigeon River. Therefore, a monthly average TSS limit of 12,549 lbs/day is recommended and a daily maximum TSS limit of 495601bs/day is recommended. Daily monitoring is required based on 15A NCAC 2B .0508 (d), Class IV facility. The temperature requirement is based on a Section 316 (a) variance determination issued by the NC Environmental Management Commission October 11, 1984 and approved by EPA August 6, 1985. In making the recommendation to retain the current 316(a) variance, DWQ scientist evaluated Blue Ridge Paper's Balanced and Indigenous Species Report and concluded that temperature could not be identified as prohibiting a Balanced and Indigenous population. In addition, DWQ staff reviewed existing temperature data and although some improvement in the instream temperature has occurred (most likely due to overall effluent flow decrease, associated with process improvements reducing temperature impacts), Blue Ridge Paper still cannot meet the North Carolina temperature requirement as indicated in Figure 2 above. Therefore, DWQ is recommending that the 316(a) variance continue, with Blue Ridge Paper conducting a Balanced and Indigenous Species Study prior to the next permit renewal. The flow limit is based on Blue Ridge Paper's current flow values and post-CMP production plus 0.9 MGD for the Town of Canton's wastewater. Future plant improvements may reduce the contribution of the mill's wastewater, however the Town of Canton is proposing to increase their contribution to the treatment plant as they expand Canton's municipal boundary. Since flows are currently approximately 80% of the permitted capacity, the Division recommends that the flow limit remain unchanged. During the next permit cycle the flow limit should be re-evaluated Fact Sheet NPDFS Renewal Page 11 and if appropriate adjusted. Due to potential inflow/infiltratiori from the Town of Canton, the Division continues the provision that requires Blue Ridge Paper to work with Canton to reduce I/I problems. Chemical Oxygen Demand (COD) monitoring is required to assess the potential impact of chemical oxygen demand from the Blue Ridge Paper wastewater effluent. Neither federal guidelines nor NC water quality standards require a limit for COD. Though no limit is proposed, the EPA has reserved COD for potential future limits. Therefore, COD monitoring will be continued. Limitations for fecal coliform are based on the contribution of domestic wastewater from the Town of Canton and the requirements of 15A NCAC 2B .0211 (b) (3) (E). Metals toxicity is a function of water hardness, since Blue Ridge Paper has demonstrated reliable compliance with toxicity, the Division recommends the elimination of hardness monitoring. Conductivity monitoring is required based on 15A NCAC 2B .0508 (d), Paper and Allied Products (Water Quality Limited Facilities), for a Class IV facility. Monitoring for total residue/total dissolved solids is required according to the existing NPDES permit. The required conductivity monitoring is sufficient to assess Blue Ridge Paper's inorganic loading to the Pigeon River. Therefore, the Division recommends removal of total residue and total dissolved solids monitoring from the permit. Limitations for pH 6.0 -9.0 are based on 15A NCAC 2B .0211 (b) (3) (G). ISSUES ASSOCIATED wrrH EFFLUENT GUIDELINE IMPLEMENTATION Relevant Background Information Over the past five-year permitting cycle, the maximum 12-month production occurred from May 1999 through April 2000. Table 3 outlines the total production of various products generated at the Canton Mill over this time period. Pulp produced at the Canton Mill is supplemented with pine and hardwood pulp purchased from off-site and pulp produced from trim or broke paper off the paper machines. The pulp is then used in paperboard and fine paper production using one of the four paper machines on-site. Table 3. Itemized Production Figures for the Maximum 12 Month Average Production Period. Product Total for 12 Month Period Units Pine Pulp 217,634.48 Air Dried Tons Hardwood Pulp 298,833.91 Air Dried Tons Purchased Pine Pulp 24,306.87 Air Dried Tons Purchased Hardwood Pulp 22,252.21 Air Dried Tons Broke Paper or Trim Pulp 46,559.08 Air Dried Tons Paperboard Production 313,625.90 Off Machine Tons Fine Paper Production 321,264.00 Off machine Tons Blue Ridge Paper has not joined the Voluntary Advanced Technology Incentives Program (VATIP) for existing direct or new direct dischargers as outlined in 40 CFR 430 Subpart B. The VATI Program was set up for new or existing direct dischargers whereby mills agree to accept enforceable effluent limitations and conditions in their NPDES permits that are more stringent than the BAT limitations, in exchange for regulatory and enforcement related rewards and incentives. Blue Ridge Paper will use steam stripping to treat process condensates, rather than hardpiping to the WWTP; thus interface with the Division of Air Quality is not necessary. Relevant Issues Daily effluent monitoring for Adsorable Organic Halides (AOX) is required. AOX is an overall test for adsorbable organic halides, which includes chlorinated organics. Trends in concentration changes have been observed between AOX and specific pollutants (dioxins, chlorinated organics) at pulp and Fact Sheet NPDES Renewal Page 12 paper mills. Therefore, any decrease in AOX may also indicate a decrease in chlorinated organics. Limits and daily monitoring for AOX are required in the EPA Cluster Rules. The cluster rules are the combined air and water rules issued by the EPA for the pulp and paper industry. The compliance/monitoring point for the AOX limits shall be as defined in the sampling plan. During the next permit cycle, the Division will review the AOX data for possible reduction in monitoring frequencies. Chloroform monitoring/limits have been added to the permit. During the previous permitting cycle, it was determined that the discharge from Blue Ridge Paper did not have a reasonable potential to exceed the allowable level. Therefore, no effluent limit is proposed. Limits contained in the NPDES permit on the bleach plant effluent are based on the EPA promulgated Effluent Guidelines for the Pulp, Paper, and Paperboard Point Source Category. Since Blue Ridge Paper operates two separate fiber lines, there shall be two compliance points for chloroform as stipulated in the sampling plan. In addition to the dioxin limits and conditions stated, above dioxins shall be limited and monitored on the effluent from the each bleach plant. 2,3,7,8 TCDD and 2,3,7,8 TCDF limits are based on the EPA promulgated Effluent Guidelines for the Pulp, Paper, and Paperboard Point Source Category. The compliance/monitoring points for each bleach plant is required as stipulated in the sampling plan. Best Management Practices (BMPs) have been added for spent pulping liquors, turpentine, and soap. At this time, Blue Ridge Paper is in compliance with the best management practices stipulated in the EPA promulgated Effluent Guidelines for the Pulp, Paper, and Paperboard Point Source Category with one remaining issue. The remaining issue deals with the BMP Plan. As part of the EPA promulgated effluent guidelines, facilities, which fall under subpart B, must develop a BMP Plan. This plan does not require the approval of any regulatory authority, but must be certified by the mill manager. Currently, the BMP Plan is in the development process and it is anticipated that this requirement will be completed prior to issuance of this NPDES permit. Per 40 CFR 430.24, the daily maximum limits for 12 chlorinated phenolics are "less than Minimum Level" (<ML) as specified in 40 CFR 430.01. The compliance/monitoring point shall be set at the effluent from the bleach plants as outlined in the sampling plan.

Fact Sheet NPDES Renewal Page 13 • The 2,3,7,8 TCDD effluent limit has been modified to 0.014 pg/L. • Two internal outfalls (002 and 003) have been added. • Removal of hardness monitoring. • Removal of total dissolved solids monitoring. • Removal of total residue monitoring. • An AOX limit and daily monitoring has been added to the permit per EPA Cluster Rules. • Dioxin, chlorophenolics and chloroform limits/monitoring have been added for the effluent from the pine and hardwood line bleach plants per EPA cluster rule. • The BMP special condition has been updated according to the requirements of the EPA Cluster Rule. • For color recommendations refer to the July 24, 2001, memo from the EPA Tech Team to the Technology Review Workgroup. This fact sheet represents North Carolina's recommendations. The Division will review all pertinent comments received during the public comment period and the September 6, 2001 public hearing. After reviewing all public comments, the Director of the Division of Water Quality and the NPDES Committee of the Environmental Management Commission will make their recommendations. PROPOSED SCHEDULE FOR PERMIT ISSUANCE Public Notice Draft Permit, temperature variance, color variance and Public August 3, 2001 Hearing Public Hearing September 6, 2001 ADDITIONAL INFORMATION CANTON MODERNIZATION PROJECT Prior to 1993, knotting hardwood brownstock was washed through one of two brownstock washer lines. After washing brownstock was screened using a two-stage fine screening process and bleached in one of the two bleaching lines. The two bleaching lines were operated independently for 'low' brightness and 'high' brightness. Since 1993, the hardwood fiberline has incorporated numerous modifications designed to increase mill performance from both an environmental and product quality standpoint. Currently, the hardwood fiberline consist of two stage knotting followed by pre-oxygen delignification washers. After pulp is processed through the oxygen delignification unit, it is washed again prior to the four stage pressurized fine screening. After screening, the pulp is bleached through one medium consistency bleach line. Prior to 1992, pine (softwood) pulp was processed through one brownstock washing line prior to the two stage screening process. After screening, pulp was processed through one of the two bleaching lines. Similar to the hardwood fiberline, the softwood fiberline bleaching was operated independently for 'low' brightness and 'high' brightness. Like the hardwood fiberline, the softwood fiberline has incorporated numerous modifications in order to enhance product quality and environmental performance. Currently, the softwood fiberline process consist of two stage knotting followed by a brownstock pre-oxygen delignification line. After the initial washing the pulp is processed through the oxygen delignification unit followed by another washing. After the second washing pulp is screened using four stage pressurized fine screen before entering a medium consistency bleach line. In addition to the improvements noted, the facility has implemented full scale bleach filtrate recycle of the pine bleach line and caustic extraction stage (Eo) recycle on the hardwood bleach line.

NAME:-2 �� � DATE: NPDES SUPERVISOR/ NAME: y— DATE: `S Z-Oo7 Fact Sheet NPDES Renewal Page 15 UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON,D.C.20460 J*RED srgTp A MEMORANDUM DATE: July 25, 2001 SUBJECT: Additional Color Removal Technologies and Their Economic Impacts on Blue Ridge Paper Products, Canton,NC FROM: EPA Tech Team' TO: Technology Review Workgroup Purpose of this Analysis As required by the 1997 Settlement Agreement,this memorandum presents a summary of an analysis of available technologies that may be employed to further reduce color discharges from the Blue Ridge Paper Products, Inc. (Blue Ridge) mill in Canton,NC. The analysis also includes a summary of the economic impact("gross margin test") of the cost of implementing identified color reduction technologies. Members of the Tech Team visited the Canton mill on March 14, 2001 to observe and gather information and data on the status of technologies implemented and color discharges at the mill since the 1997 evaluation. This final memorandum incorporates analyses of the data gathered from that visit, and Blue Ridge's response to EPA's follow-up request for additional technical and financial data. This final memorandum is based on the May 4, 2001 preliminary draft memorandum, and revisions to the July 10,2001 draft final memorandum, based on a review of Blue Ridge's comments,the June 8, 2001 Bleach Environmental Process Evaluation and Report (BEPER) and subsequent comments by Liebergott and Associates and GL&V Pulp Group, Inc, and additional comments from the Clean Water Fund of North Carolina, and the States of Tennessee and North Carolina. This memorandum presents to the Technology Review EPA Tech Team is comprised of--Mark Perez,EPA/EAD;Karrie-Jo Shell,EPA Region 4;Don Anderson, EPA/EAD;Betsy Bicknell,ERG,contractor;Neil McCubbin,subcontractor to ERG;Dan Bodien,subcontractor to ERG. Workgroup (TRW) process improvements evaluated by the Tech Team and considered to be available technologies and briefly addresses relevant technologies evaluated in the BEPER. Background and History Blue Ridge operates a bleached papergrade kraft pulp and paper mill in Canton,NC, which it purchased from Champion International Corporation in May 1999. Operations at the mill began in 1908, but the mill has been extensively modernized, most recently in 1993. The mill currently operates an 800 tpd hardwood pulping line and a 600 tpd softwood pulping line. After cooking, pulp from each line is further delignified in single-stage oxygen delignification systems installed in 1993. Hardwood pulp is subsequently bleached with a DEoD sequence; pine pulp is bleached with a DEopD sequence. Target brightness is 85 ISO. Up to 80 percent of the filtrate flow from the pine bleach line is returned to the recovery cycle using the unique bleach filtrate recovery (BFRTm)process, developed by Champion. A portion of the hardwood line bleach plant Eo- stage filtrate flow is also recovered. Blue Ridge produces 250,000 tons per year of uncoated paper including offset,tablet and envelope grades. The mill also produces 281,000 tons per year of bleached paperboard used for liquid packaging and paper cups, including FDA approved grades for milk and juice cartons. Since November 2000,pulp production has been reduced by approximately 30 percent as the result of a major project to upgrade the No. 19 bleached paperboard machine. Continued Color Reduction Opportunities Since the 1997 NPDES Permit The Canton Mill's 1997 NPDES permit included a schedule requiring continued study, evaluation, and pursuit of effluent color reduction opportunities. Champion and Blue Ridge submitted a series of reports to the NC Department of Environment and Natural Resources, Division of Water Quality, evaluating the performance of the BFR process, end-of-pipe color reduction technologies, and practices for minimizing color losses from manufacturing processes. Since 1997 Blue Ridge has: • continued full-scale operation of BFR for the pine line; • concluded that full-scale BFR is not feasible for the hardwood line, but implemented partial reuse of a portion of the Eo-stage filtrate as an effective color-reduction approach; • identified and implemented several practices for reducing losses of highly-colored black liquor from manufacturing processes; and • evaluated 16 end-of-pipe color removal technologies and determined that they were presently economically and/or technically infeasible for the Canton mill. Page 3 Process Improvements Analyzed by the Tech Team The Tech Team identified five mill improvements capable of further reducing the discharge of color in the mill effluent. For each of these improvements, technical feasibility, capital and operating costs, and potential color reduction were reviewed. Each improvement can be implemented independently of the others or in any combination. The costs incurred to implement the improvements are additive, however separate evaluations are necessary to accurately estimate the associated color reduction achieved by implementing any combination of improvements. End-of-pipe color treatment technologies (e.g., chemically assisted clarification with sludge dewatering and disposal)typically require initial capital investment and ongoing operating expenses, not savings, and are likely to incur non-water quality environmental impacts. For this reason,the Tech Team focused on pollution prevention approaches that offer the potential to be more cost-effective: color reduction in low flow, highly color-concentrated wastestreams, through manufacturing process changes or in-process treatment. The first two process improvements, discussed below (improvements in BFR reliability and leak and spill prevention and control -Best Management Practices (BMPs)), are improvements which the Tech Team concludes offer the highest certainty for technical feasibility and color reduction. Blue Ridge also identified these technologies as feasible color reduction opportunities that will be implemented, but differed from the color reduction estimates included in this memorandum. The next two process improvements (ozone addition to an existing chlorine dioxide bleaching stage on the hardwood fiber line; adding a second stage to the current oxygen delignification system on the softwood fiber line) also were evaluated by Liebergott, et. al., as feasible color reduction opportunities. Additional technical evaluation and/or laboratory testing would be appropriate to reliably determine the technical details of how to incorporate these processes into the existing fiber lines and to more accurately predict their achievable color reduction, and the relationship of these technologies to BFR. Additional analyses would be appropriate to determine the most cost-effective design and the most economically feasible schedule for implementing one or both of these improvements. The fifth process improvement, color treatment for the chloride removal process (CRP)purge stream (one of the two key components of the BFR process), has the potential for additional color reduction. However, based upon initial bench-scale treatability studies by Blue Ridge, further study of additional color treatment technologies is necessary. Process optimization on both the hardwood and softwood fiber lines; as recommended in the BEPER, is anticipated to Page 4 provide additional color reduction and is identified as the sixth process improvement. It was concluded that the process optimization option was among those with the highest certainty for technical feasibility and color reduction. All color reductions resulting from the mill improvements are estimates based solely on available data and information. While the Tech Team has concluded that these technologies would reduce the color discharge from the Canton mill, there is a lack of directly comparable operating experience with these technologies in other bleached papergrade kraft mills that can be used to develop precise predictions of the extent of the color reduction benefits. The BEPER evaluated additional in-process technology options for color discharge reduction potential, including the implementation of a hot pressurized peroxide-enhanced extraction stage in both fiber line bleach plants. At this time, the Tech Team does not have sufficient information to confirm the applicability of this technology at the Canton mill nor relevant data to predict its potential color discharge reduction capabilities. Therefore, while this memorandum does not address this technology option, it may be feasible for implementation by Blue Ridge and contribute to reducing color. In addition,the Tech Team did not analyze nor did the BEPER recommend a Totally Chlorine-Free (TCF) bleaching option because of the high cost of this technology and the lack of experience in producing and successfully marketing products made by Blue Ridge at the Canton mill. 1. BFR reliability improvement. One of the two key elements in BFR is the Metals Removal Process (MRP). Blue Ridge has found that this process element has been more challenging and expensive to maintain than originally planned. The target BFR recycle rate (percent closure) for the pine line is 80 percent. Due to unforeseen equipment failures (e.g., ion exchange media) and metallurgy problems (e.g., erosion of multi-media filtration tank lining) in the MRP,however, the pine line closure has averaged only 74 percent from October 1998 to the present. Blue Ridge has undertaken improvements to the MRP system in order to maintain the process closure rate and increase operating time. Improvements include rebuilding piping and valves, and changing construction materials and metallurgy to better withstand the chemical and physical stress experienced in the BFR system. Blue Ridge estimates that if BFR closure is maintained at 80 percent, annual average final effluent color discharge will be reduced by 1,000 to 1,200 lbs/day. At this time, the Tech Team has no means of making an alternative quantitative prediction of final effluent color reduction to compare to the Blue Ridge estimate. Page 5 2. Improved black liquor leak& spill collection and control(BMPs). The Canton mill has an extensive spill recovery system. Sumps in this system, including one sump added in the court yard adjacent to the digester house as required by the 1997 Settlement Agreement, are equipped with pumps that are activated automatically when sensors detect wastewaters with high conductivity and color. High conductivity material is routed to the recovery system. Further improvements to the black liquor collection system include: • continuous improvement of operating practices so more leaks and spills are recovered rather than discharged to sewer; • further improvement in preparation for planned outages to maximize capture of tank clean-out waste and routing to recovery; • further reducing clean water that continuously runs into sewers to prevent dilution of smaller spills and facilitate recovery of highly colored wastewaters; and • further improvement in the equipment used for handling of knots rejects to prevent black liquor leaks into the recovery sumps. The plot below shows the color of wastewater treatment influent at the Canton mill. The variability of influent color discharge to wastewater treatment is attributed to color discharge peaks that represent, in part, unplanned spills or leaks discharged to sewers or intentional diversions of highly-colored black liquor or other color sources routed to sewers during mill equipment shutdowns. 100 kg/t Figure 1 75 Daily color at influent to W WTP for Canton 50 25 0 30 50 90 120 150 180 Page 6 Due to the nature of the manufacturing processes and'practical equipment operation and reliability, all spills and color losses to sewers cannot be fully anticipated,predicted, and completely contained. However, a comparison of the variability of the Canton mill influent color data to available primary influent color data at another bleached papergrade kraft mill indicate that a detailed review of the spill prevention and recovery system at the Canton mill (by mill staff or external consultants), including involvement by the mill operators, can further uncover the causes of and better quantify black liquor losses and other color sources that can be avoided or recovered. This will result in an overall reduction in color discharge, both in long-term average and variability. Through improved planning of mill equipment shutdowns, continuing efforts to minimize process operation variability, and increased recovery of highly-colored leaks and spills, discharges of highly colored material to the wastewater treatment system can be reduced more consistently below existing levels. Further reducing peaks in color discharges within the mill and preventing highly colored flows from reaching the wastewater treatment system will further reduce the variability of color discharges from the wastewater treatment system to the Pigeon River. For example, limiting the color of the primary clarifier influent to less than 70,000 lb/day through continuing efforts to improve the mill's BMP system and process operations would reduce the color loadings from mill processes to the end-of-pipe wastewater treatment system by more than 8,000 lb/day. The Canton mill operated under this primary clarifier influent color threshold approximately 74 percent of 2000, excluding November through December 2000. This time period was considered not to be representative of steady-state operations because of the reduced pulp production resulting from upgrading the No. 19 bleached paperboard machine. Assuming the average reduction of 45 percent across this wastewater treatment system for"brown" color derived from black liquor, this would result in a minimum decrease of 4,400 lb/day in the average final effluent color load. Clean water, such as packing gland water,presently flows in several sewers with recovery sumps. These colorless streams dilute other colored wastestreams, such as small black liquor leaks and spills,to the point where the in-stream conductivity is too low to trigger recovery. By eliminating clean water streams or diverting them away from sewers that collect black liquor leaks and spills, wastewater streams with elevated color can be recovered more readily, resulting in a reduction in color discharge to the end-of-pipe wastewater treatment system. Also, the unintentional but intermittent discharge to the sewer of filtrate from knots and screen rejects can be recovered. Page 7 At this time, the Tech Team has no basis for determining an accurate correlation between unaccounted color and sewer generated color, as reported in Section 2 of the Canton Mill Environmental Performance Update presented by Blue Ridge during the March 14, 2001 Tech Team Canton mill visit. During the March 14 visit, Blue Ridge staff indicated that results of studies of sewer generated color showed axelationship between bleach plant filtrate pH and temperature and unaccounted color generated in mill sewers. By operating within the range of pH and temperatures identified during the studies the Canton mill has had some success in controlling this source of unaccounted color. Based on this information,the Tech Team concludes that by further reducing process operation variability, including operating within the pH and temperature range identified during the studies,the mill can continue to also minimize sewer generated color, thereby reducing one source of unaccounted color. Reducing overall color discharges through BMPs and other management practices will likely further reduce remaining unaccounted color. However, additional studies are necessary to further develop any relationship between accounted and unaccounted color sources. As noted above, analysis of primary clarifier influent color loading data demonstrates that color loading to the wastewater treatment system of lower than 70,000 lbs/day is possible during steady-state operations. Through continuing efforts to minimize unplanned spills and leaks and intentional discharges of colored streams and continuing efforts to minimize process operation variability,the Canton mill can achieve further reduced primary clarifier influent color loads and subsequent final effluent color discharge within this range on a more consistent basis than demonstrated in 2000 (i.e., more than 74 percent of the time). On this basis,the Tech Team concluded it is feasible to reduce final effluent color by more than 5,000 lbs/day through improved black liquor leak and spill collection and control. 3. Ozone/Chlorine dioxide stage for hardwood bleach line. Ozone is used in more than ten kra8 mills around the world to bleach pulp, including two in the US and one in Canada. There are several process configurations, but the most common is to operate an ozone (Z)mixer and reactor immediately upstream of a chlorine dioxide reactor, without any washing between the application of the two chemicals. This is known as a"ZD" stage. A system of this type was retrofitted in the Domtar mill at Espanola, Ontario, Canada in 1999. Bleaching with ozone on the hardwood line, one of the Domtar mill's two pulp lines, resulted in a 27 percent reduction in the discharge of color in the combined mill treated effluent' The conversion to a ZD stage z Munro,Fred and John Griffiths,Operating Experience with an Ozone-based ECF Bleaching Sequence,Tappi,1000. 3 Aid. Page 8 would reduce the use of chlorine dioxide and caustic chemicals for bleaching in exchange for ozone. The energy requirements for ozone production would be offset by the energy savings from less chlorine dioxide and caustic production, resulting in a net reduction in energy consumption with the ZD stage. As of September 2000, the long-term average color discharge from Canton's hardwood bleach line was 12,800 pounds/day 4. The Espanola experience suggests that implementation of a ZD stage in the hardwood bleach plant at the Canton mill could reduce the filtrate color discharge by 3,000 to 6,4001bs/day. Based on comments received,the Tech Team acknowledges that operating parameters, such as wood species processed and technology supplier performance guarantees,may influence the practical color reduction achievable through implementation of a ZD stage at the Canton mill, in comparison to the Espanola experience. These estimates are based solely on the demonstrated performance and the Tech Team's assumption of color sources at the Espanola mill, confirmed at the recent Pulp and Paper Technical Association of Canada (PAPTAC) meeting in Thunder Bay, Ontario. Laboratory bleaching trials and possible communication between Blue Ridge and Domtar staff would be necessary to reliably predict the achievable color reduction possible with this option for the Canton mill. The technical evaluation of this process improvement included in the BEPER yielded a hardwood filtrate color discharge reduction within the range of Tech Team estimates. 4 2mi stage OD for pine line. Oxygen delignification(OD) on the Canton Mill pine line is a single stage system installed in 1993. It has been concluded that retrofitting a second OD stage for the pine line could contribute to reduced color discharges in two ways. The first would be a reduction in color for those filtrates presently not captured and reused in the BFR process. The second would be a color reduction in the Chloride Removal Process (CRP) purge stream as a result of less chloride from chlorine dioxide used for bleaching. Costs were estimated for a reactor with oxygen mixer and chemical charge equipment installed upstream of the existing reactor. Previously,the Tech Team anticipated increasing the kappa number(lignin content) of the cooked pulp from 24 to 32 and utilizing a two-stage OD system to reduce kappa number from 32 to 11, an approximate 65 percent kappa reduction across the two- stage system. Based upon comments from BRP and further technical analysis, and review of the BEPER, it was concluded that it is technically feasible for a two-stage OD system at the Canton Jacobs Engineering Group,2001 Color Removal Technology Assessment,February 2001. Page 9 mill to achieve an overall reduction of 50 percent in kappa number,rather than 65 percent as previously anticipated. Therefore, with the Canton mill continuing to pulp to a kappa number of 24, the new two-stage OD system would reduce pulp kappa number into the bleach plant from the current output of 16 to about 12, corresponding to a 50 percent kappa number reduction from the current digester output of 24. The quantity of color released from the bleach plant will be reduced in proportion to the reduction of the input kappa number. By decreasing the kappa number of the pulp fed to the bleach plant from kappa 16 to 12 with a two-stage OD system, the quantity of chemicals required in the first two stages of the bleach plant can be reduced,because there is less lignin present in the incoming pulp to remove by bleaching. The reduction in chlorine dioxide used for bleaching would result in a proportional reduction in chloride load to the CRP and reduce color discharged from the purge stream in proportion to the reduction in chloride being treated. In response to comments received, it has been concluded that implementing a two-stage OD system without increasing the kappa number of the cooked pulp from 24 to 32 would not achieve a 1.5 percent pulp yield gain as anticipated with increasing digester kappa number and achieving greater delignification with the proposed two-stage OD system. However, operating a two-stage OD system with.a higher than 50 percent delignification rate and a digester kappa number higher than currently employed at the Canton mill is commonly seen at comparable bleached papergrade kraft mills. Therefore,the Tech Team anticipates that additional process engineering will maximize the benefits of a two-stage OD system at the Canton mill and enable the mill to capture the increased delignifcation and yield gain potential of this technology and achieve annual wood cost savings of up to approximate$950,000 from up to a 1.5 percent yield increase across the proposed two-stage OD system. Based on additional information supplied by Blue Ridge regarding operational limitations of the BFR system, the Tech Team concludes that a two-stage OD system would not have a significant impact at this time on the Canton mill's ability to increase BFR closure rate above 80 percent on a day-to-day basis. For this analysis, it was estimated preliminarily that a second OD stage could reduce total influent color discharge to the wastewater treatment system by 1,500 to 2,000 lb/day from reductions in pine line bleach plant filtrate color and CRP purge stream color. Page 10 The technical evaluation of two-stage OD included in the BEPER yielded reduction in color discharge influent to the wastewater treatment system within the range of the Tech Team estimates. S. Color Treatment of CRP purge stream. The Chloride Removal Process (CRP)purge is a low flow,highly concentrated waste stream. Color is typically 50,000 pcu, in a 10 gpm (0.01 MGD) flow. The CRP purge contributes up to approximately 5,000 lbs/day (13 percent)to the total mill loading to the wastewater treatment system influent, but only 0.06 percent of the discharge flow. It was originally speculated that it may be feasible to reduce the color in this stream by precipitating the colored organic material with lime at a dosage of 20 g/L5, and burning the resulting sludge with the main lime mud stream fed to the mill's lime kiln. Laboratory trials would be necessary to test the feasibility of color removal from the CRP purge stream by lime treatment. Blue Ridge subsequently conducted laboratory trials of color precipitation using four calcium compounds, including lime mud, fresh lime, calcium chloride, and milk of lime. The preliminary results of these trials show that at a dosage of 20 g/L, none of the compounds tested reduced color in the CRP purge stream. Although color removal was demonstrated at higher dosage rates, increased chemical usage would result in substantially higher operating costs, require larger sized equipment at higher capital cost, and also result in a higher production rate of sludge to be burned in the mill's lime kiln. Excess sludge produced from this process that is not burned must be landfilled at additional cost. Based on preliminary laboratory trials,Blue Ridge concluded that lime treatment of the CRP purge is not a feasible color reduction option for the Canton mill. However, the Tech Team recommends additional review of other innovative technologies for treatment of color in the CRP purge stream, such as the application of the X-Filter process recently implemented at a totally chlorine free (TCF)mi116. By minimizing color contributions from this stream,the potential exists to achieve a significant reduction in primary influent color discharge of up to 5,000 lbs/day. 5 NCASI Technical Bulleting No.239,The Mechanisms of Color Removal in the Treatment of Pulping and Bleaching Effluents with Lime.1. Treatment of Caustic Extraction Stage Bleaching Effluent July, 1970. 6 Comments on the Draft Report on Additional Color Removal Technologies and Economic Impacts for BRPP,Hope Taylor,Clean Water Fund of North Carolina,July 18,2001 Page 11 6. Process Optimization. The BEPER identified sixteen recommendations for optimizing the hardwood and softwood fiber lines, focusing mainly on the current OD systems and bleaching operations. It was estimated that a reduction could be achieved in chlorine dioxide use in the first bleaching stage of up to 27 percent for the hardwood line and 18 percent for the softwood line. The reduction in chlorine dioxide use would result in a bleach plant filtrate color reduction of up to 700 lbs/day from the hardwood line and up to 400 lbs/day from the softwood line. The Tech Team estimated an additional color reduction from the CRP purge stream of 600 lbs/day resulting from the decreased chlorine dioxide usage. At this time, the Tech Team has no means of making an alternative quantitative prediction of bleach filtrate color reduction to compare to estimates presented in the BEPER. Therefore, it is estimated that through efforts by mill staff to maximize the color reduction benefits from the process optimization opportunities identified by Liebergott, et, al., the Canton mill would achieve a total color reduction of 1,700 lbs/day in wastewater treatment system influent. Color Reduction Summary The Tech Team estimates that by improving BFR reliability and black liquor leak and spill collection and control, the Canton mill final effluent will be reduced by more than 5,000 lbs/day. Process optimization, as outlined in the BEPER, would result in a further final effluent color reduction of approximately 1,400 lbs/day. This assumes the average color reduction of 45 percent across the existing wastewater treatment for the CRP purge stream and other"brown" color sources derived from black liquor and no reduction in color from bleach plant filtrates. Table 1 presents a summary of the estimated reductions in final effluent color attainable with the highest certainty by implementing improved BFR reliability, improved BMPs, and process optimization. Page 12 Table 1: Summary of Process Improvements and Associated Color Reductions (Highest Certainty) Process Improvement Influent Final Effluent Color Color Reduction Reduction (lbs/day) (lbs/day) 1 BFR reliability improvement --- 1,000-1,200 2 Improved black liquor leak& spill collection and --- >5,000 control 6 Process Optimization 1,700 1,400 TOTAL FINAL EFFLUENT COLOR REDUCTION >7,400 Additional potential mill improvements to reduce color discharge at the Canton mill were also identified. These process improvements require further study to more accurately determine achievable color reduction and thus are not recommended at this time for immediate implementation. These improvements include a ZD stage in the hardwood bleach plant, with a preliminary estimate of a 3,000 to 6,400 lbs/day color load reduction in influent to the wastewater treatment system, and a second OD stage for the pine line, with a preliminary estimate of a 1,500 to 2,000 lb/day color load reduction in influent to the wastewater treatment system. Table 2 presents a summary of preliminary estimates of color reductions for these two additional process improvements that need further study. Reductions presented in Table 2 are preliminary estimates with reduced certainty compared to those presented in Table 1, but are based upon identified technology options available for the Canton mill. t Page 13 Table 2: Summary of Process Improvements and Associated Additional Color Reductions Needing Further Study (Reasonable Certainty) Process Improvement Influent Final Effluent Color Color Reduction Reduction (lbs/day) (lbs/day) 3 Ozone/Chlorine Dioxide stage for hardwood bleach 3,000-6,400 3,000-6,400 line 4 2"d stage OD for pine line 1,500-2,000 1,100-1,400 TOTAL FINAL EFFLUENT COLOR REDUCTION 4,100 -7,800 Table 3 presents a preliminary estimate of color reduction potential for the removal of color from the CRP purge stream.

Potential for additional color load reduction up to 2,750 lbs/day in final effluent to the Pigeon River. Table 3 presents potential color reduction estimates with the lowest certainty.

Costs could not be developed at this time for process optimization or CRP treatment and thus are not presented. However, costs for these improvements should be modest.

Blue Ridge Paper Products is owned 55 percent by KPS Special Situations Fund, L.P. and 45 percent by the employees of Blue Ridge Paper through an employee stock ownership plan. At the time of the 1997 report EPA documented substantial losses over five years for the Canton Mill and Champion had just announced its intention to sell or close the mill. However, because of the sale of the mill to the Blue Ridge, the previous data are not comparable to the more recent data. Further,the data submitted by Blue Ridge is still confidential, so this report cannot present as much detail as the 1997 report. The current analysis is based on information submitted by Blue Ridge covering part of 1999 (May-December) and all of 2000 (all of the existing financial data for the company). The results may be relatively uncertain because of the lack of data and the company may be too young for the current data to reflect its ultimate financial health. EPA used three measures of financial health(gross profit test, discounted cash flow, and Altman's Z)7 to assess the impact of 'See Interim Economic Guidance for Water Quality Standards:Workbook,EPA 823-B-95-002,March 1995,and Economic Analysis for the National Emission Standards for Hazardous Air Pollutants for Source Category:Pulp and Paper Production;Effluent Limitations Guidelines,Pretreatment Standards,and New Source Performance Standards: Pulp,Paper,and Paperboard Category—Phase 1. Page 15 air emissions control technologies and devices (not addressed in this memorandum, such as MACT II and regional NOX control) and wastewater compliance costs (separate and combined) on the mill and company. The costs for the wastewater control options presented in Table 3 do not change the financial status of the mill or company. However, the costs for some of the air emissions control options do impact the health of one or both entities. When the wastewater costs are added to costs for air emissions control, the impacts of the water costs do not change the financial status of either the mill or company when compared to the impact of the air costs alone.
