E. Dee Freeman Governor Director Secretary June 1,2012 Mr. Paul Dickens Manager,EHS Blue Ridge Paper Products Inc. PO Box 4000 Canton,North Carolina 28716 Subject: NPDES Permit Modification Partial Settlement/Temperature NPDES Permit NC0000272 Blue Ridge Paper Products Haywood County Dear Mr. Dickens: The Division issued the subject permit on May 26, 2010, which was subsequently contested by Cocke County TN et al based on temperature and color concerns. Following negotiations, a Partial Settlement Agreement pursuant to N.C. General Statute 150B-31(b) was signed April 24, 2012 for the temperature claims against the permit, while a hearing for the color claims was stayed pending results of a color perception study. This permit modification reflects the partial settlement agreement for temperature. Specifically, the modification results in a more stringent instream temperature timeframe for compliance, as follows: • In Effluent Sheet A(1), Footnote 11, changed "shall not exceed 32 degrees C during the months of July, August, and September" from a Monthly Average instream temperature limitation to a Weekly Average instream limitation. Likewise, changed "shall not exceed 29 degrees C during the months of October through June" from a Monthly Average instream temperature limitation to a Weekly Average instream limitation. All other conditions in Footnote 11 remain the same. This permit modification becomes effective immediately, and is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007. 1617 Mail Service Center,Raleigh,North Carolina 27699-1617 Location:512 N.Salisbury St.Raleigh,North Carolina 27604 Phone:919-807-63001 FAX:919-807-6492 Internet:www.ncwaterguality.org Oile An Equal Opportunity 1 Affirmative Action Employer NorthCarohna Naturally NE-.Paul Dickens June 1,2012 Page 2 of 2 Please replace the old Effluent Sheet A(1) in your permit with the modified page attached to this cover letter.

Sample Location:I-Influent,El—Effluent,Pigeon River-Instream sampling as specified in A. (5.)Instream Monitoring Special Condition. 2. AOX monitoring shall be in accordance with the Sampling Plan for Cluster Rule Parameters(dated March 19, 2001)or subsequent modifications approved by the Division. AOX data shall be submitted on a quarterly basis along with other Effluent Guideline chemical data;refer to A. (7.) Effluent Guideline Sampling Plan Special Condition. 3. Annual average color limit is 38,020 lb/day,which will decrease to 32,000-36,000 lb/day no later than 4 years after the permit effective date. See A.(8.) Color Analysis and Compliance Special Condition.All color limits are measured as true color. NPDES Permit:NC0000272 4. The daily average effluent dissolved oxygen concentration shall not be less than 6.0 mg/L. See A.(10.) Dissolved Oxygen Special Condition. 5. The permittee shall report daily and monthly average effluent temperature. 6. The pH of the effluent shall not be less than 6.0 nor greater than 9.0(on the standard units scale). 7. Chronic Toxicity(Ceriodaphnia)at 90%Effluent Concentration:March,June, September,December(see A. (4.)Chronic.Toxicity Permit Limit(Quarterly)). 8. Trichlorophenol and Pentachlorophenol limits and monitoring are provisionally waived since the facility has certified that chlorophenolic biocides are not used at this facility. If the facility changes operations to include chlorophenolic biocide,the Permittee shall notified the Division prior to use and the limits and monitoring requirements shall become immediately effective. 9.

The Weekly Average instream temperature measured at a point 0.4 miles downstream of the discharge location shall not exceed 320C during the months of July,August,and September and shall not exceed 29°C during the months of October through June. The monthly average instream temperature measured at this location shall not exceed the monthly average instream temperature of the upstream monitoring location by more than 8.5°C.This value can be adjusted based on the results of thermal modeling[See Special Condition A.(12.)Temperature Variance Review Special Condition]. 12. Monitoring should be conducted in conjunction with Whole Effluent Toxicity Testing. 13. Monitoring should be conducted in conjunction with zinc monitoring. 14. Monitoring shall be conducted upstream of the discharge(mile marker 63.8)and at Fiberville Bridge for 1 year (12 months).
