DANIEL SMITH NORTH CAROLINA Director Environmental Quality January 26, 2021 Mr.Wallace McDonald, General Manager Blue Ridge Paper Products, Inc. dba Evergreen Packaging • P.O. Box 4000 Canton,North Carolina 28716 Subject: Draft NPDES Permit Permit NC0000272 Canton Mill WWTP Haywood County Facility Grade IV Dear Mr. Griswold: Enclosed with this letter is a copy of the draft permit for your facility. Please review this permit very carefully to ensure thorough understanding of the conditions and requirements it contains. The draft permit contains the following significant changes from your current permit: 1) Section A. (8.) Requirements for Color Analysis and Compliance Special Condition of the permit has been updated. 2) Section A. (9.) Dioxin Monitoring Special Condition has been updated and the number of the fish tissue sampling analysis has been reduced. 3) Section A. (12.) Clean Water Act Section 316(a) Thermal Variance has been updated. 4) Section A. (14.) Mixing Zone has been added to the permit. 5) The flow limit has been increased to 34.0 MGD to account for increased water usage resulting from the installation of two new wet scrubbers on coal fires boilers for boiler MACT compliance and change in operation of the Riley Bark boiler for SO2 control. 6) The Color Variance is terminated and a new instream color compliance requirement has been added to the permit to replace the Color Variance,please see Footnote#16 (Part I Section A. (1.)). 7) Chloroform limits have been recalculated to reflect the current production level (Internal Outfall 002 and Internal Outfall 003). 8) AOX (adsorbable organic halides) limits have been recalculated to reflect the current production level (Outfall 001). The calculation indicated the need to increase the limits. However,the current limits were kept to provide an additional protection for the receiving stream. 9) Pentachlorophenol and trichlorophenol limits have been recalculated to reflect the current production level (Outfall 001). The calculation indicated the need to increase the limits.

Page 11 of 21 Permit Number: NC0000272 A. (6.) BEST MANAGEMENT PRACTICES(BMP)SPECIAL CONDITION [NCGS 143-215.1] The permittee must implement the BMPs specified below. The primary BMP objective is to prevent leaks and spills of spent pulping liquors,soap,and turpentine. A secondary objective is to contain, collect,and recover at the immediate process area,or otherwise control,those leaks,spills,and intentional diversions of spent pulping liquor,soap,and turpentine that do occur. BMPs must be developed according to best engineering practices and must be implemented in a manner that takes into account the specific circumstances at the mill. Section A. BMP Implementation Requirements 1. The permittee must return spilled or diverted spent pulping liquors,soap,and turpentine to the process to the maximum extent practicable as determined by the mill,recover such materials outside the process,or discharge spilled or diverted material at a rate that does not disrupt the receiving wastewater treatment system. 2. The permittee must maintain a program to identify and repair leaking equipment items. This program must include:(i)Regular daily visual inspections of process area with equipment items in spent pulping liquor,soap,and turpentine service;(ii)Immediate repair of leaking equipment items,when possible. Leaking equipment items that cannot be repaired during normal operations must be identified,temporary means for mitigating the leaks must be provided,and the leaking equipment items repaired during the next maintenance outage;(iii)Identification of conditions under which production will be curtailed or halted to repair leaking equipment items or to prevent pulping liquor, soap,and turpentine leaks and spills;and(iv)A means for tracking repairs over time to identify those equipment items where upgrade or replacement may be warranted based on frequency and severity of leaks,spills,or failures. 3. The permittee must operate continuous,automatic monitoring systems that the mill determines are necessary to detect and control leaks,spills,and intentional diversions of spent pulping liquor,soap, and turpentine.These monitoring systems should be integrated with the mill process control system and may include,e.g.,high level monitors and alarms on storage tanks;process area conductivity(or pH)monitors and alarms;and process area sewer,process wastewater,and wastewater treatment plant conductivity(or pH)monitors and alarms. 4. The permittee must maintain a program of initial and refresher training of operators,maintenance personnel,and other technical and supervisory personnel who have responsibility for operating, maintaining,or supervising the operation and maintenance of equipment items in spent pulping liquor,soap,and turpentine service.The refresher training must be conducted at least annually and the training program must be documented. 5. The permittee must prepare a brief report that evaluates each spill of spent pulping liquor,soap,or turpentine that is not contained at the immediate process area and any intentional diversion of spent pulping liquor,soap,or turpentine that is not contained at the immediate process area.The report must describe the equipment items involved,the circumstances leading to the incident,the effectiveness of the corrective actions taken to contain and recover the spill or intentional diversion, and plans to develop changes to equipment and operating and maintenance practices as necessary to prevent recurrence.Discussion of the reports must be included as part of the annual refresher training. 6. The permittee must maintain a program to review any planned modifications to the pulping and chemical recovery facilities and any construction activities in the pulping and chemical recovery areas before these activities commence. The purpose of such review is to prevent leaks and spills of spent pulping liquor,soap,and turpentine during the planned modifications,and to ensure that construction and supervisory personnel are aware of possible liquor diversions and of the requirement to prevent leaks and spills of spent pulping liquors,soap,and turpentine during construction. 7. The permittee must install and maintain secondary containment(i.e.,containment constructed of materials impervious to pulping liquors)for spent pulping liquor bulk storage tanks equivalent to the Page 12 of 21 Permit Number: NC0000272 volume of the largest tank plus sufficient freeboard for precipitation.An annual tank integrity testing program,if coupled with other containment or diversion structures,may be substituted for secondary containment for spent pulping liquor bulk storage tanks. 8. The permittee must install and maintain secondary containment for turpentine bulk storage tanks. 9. The permittee must install and maintain curbing,diking or other means of isolating soap and turpentine processing and loading areas from the wastewater treatment facilities. 10. The permittee must conduct wastewater monitoring to detect leaks and spills,to track the effectiveness of the BMPs,and to detect trends in spent pulping liquor losses. Such monitoring must be performed in accordance with Section E. Section B. BMP Plan Requirements 1. The permittee must maintain and implement a BMP Plan.The BMP Plan must be based on a detailed engineering review as described in this section. The BMP Plan must specify the procedures and the practices required for the mill to meet the requirements of Section A,the construction the mill determines is necessary to meet those requirements including a schedule for such construction,and the monitoring program(including the statistically derived action levels)that will be used to meet the requirements of Section E.The BMP Plan also must specify the period of time that the mill determines the action levels established under Section D may be exceeded without triggering the responses specified in Section E. 2. The permittee must conduct a detailed engineering review of the pulping and chemical recovery operations--including but not limited to process equipment,storage tanks,pipelines and pumping systems,loading and unloading facilities,and other appurtenant pulping and chemical recovery equipment items in spent pulping liquor,soap,and turpentine service--for the purpose of determining the magnitude and routing of potential leaks,spills,and intentional diversions of spent pulping liquors,soap,and turpentine during the following periods of operation: (i)Process start-ups and shut downs;(ii)Maintenance; (iii)Production grade changes; (iv)Storm or other weather events; (v) Power failures;and(vi)Normal operations. 3. 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 practices and engineered controls are necessary to reduce significantly the likelihood of spent pulping liquor,soap,and turpentine leaks, spills,or intentional diversions from the immediate process areas,including a schedule for implementation of such practices and controls. 6. The BMP Plan,and any amendments thereto,must be reviewed by the senior technical manager at the mill and approved and signed by the mill manager.Any person signing the BMP Plan or its amendments must certify to the Division under penalty of law that the BMP Plan(or its amendments) has been prepared in accordance with good engineering practices and in accordance with this Page 13 of 21 Permit Number: NC0000272 regulation.The permittee is not required to obtain approval from the Division of the BMP Plan or any amendments thereto. Section C. BMP Recordkeeping Requirements 1. The permittee must maintain on its premises a complete copy of the current BMP Plan and the records specified in Section C.2 and must make such BMP Plan and records available to the Division for review upon request. 2. The permittee must maintain the following records for three years from the date they are created: (i) Records tracking the repairs performed in accordance with the repair program described in Section A; (ii)Records of initial and refresher training conducted in accordance with Section A;(iii)Reports prepared in accordance with Section A;and(iv)Records of monitoring required by Sections A and E. Section D. Establishment of Wastewater Treatment System Influent Action Levels 1. The permittee must conduct a monitoring program per Section D.2,for the purpose of defining wastewater treatment system influent characteristics(or action levels),described in Section D.3,that will trigger requirements to initiate investigations on BMP effectiveness and to take corrective action. 2.- The permittee must employ the following procedures in order to develop the action levels required by Section D: • Monitoring parameters.The permittee must collect 24-hour composite samples and analyze the samples for a measure of organic content(e.g.,Chemical Oxygen Demand(COD)or Total Organic Carbon(TOC)).Alternatively,the mill may use a measure related to spent pulping liquor losses measured continuously and averaged over 24 hours(e.g.,specific conductivity or color). • Monitoring locations.The permittee must conduct monitoring at the point influent enters the wastewater treatment system. For the purposes of this requirement,the permittee may select alternate monitoring point(s)in order to isolate possible sources of spent pulping liquor,soap,or turpentine from other possible sources of organic wastewaters that are tributary to the wastewater treatment facilities(e.g.,bleach plants,paper machines and secondary fiber operations). 3. The permittee must maintain an influent action levels monitoring program using the procedures specified in Section D and must maintain action levels based on the results of that program.A wastewater treatment influent action level is a statistically determined pollutant loading determined by a statistical analysis of six months of daily measurements.The action levels must consist of a lower action level,which if exceeded will trigger the investigation requirements described in Section E,and an upper action level,which if exceeded will trigger the corrective action requirements described in Section E. 4. The pennittee must complete a second six-month monitoring program using the procedures specified in Section D and must establish revised action levels based on the results of that program.The initial action levels shall remain in effect until replaced by revised action levels based on Section D5 requirements. 5. Action levels developed under this Section must be revised using six months of monitoring data after any change in mill design,construction,operation,or maintenance that materially affects the potential for leaks or spills of spent pulping liquor,soap,or turpentine from the immediate process areas. Section E. BMP Monitoring,Corrective Action,and Reporting Requirements 1. The permittee must conduct daily monitoring of the influent to the wastewater treatment system in accordance with the procedures described in Section D for the purpose of detecting leaks and spills, tracking the effectiveness of the BMPs,and detecting trends in spent pulping liquor losses. Page 14 of 21 Permit Number: NC0000272 2. Whenever monitoring results exceed the lower action level for the period of time specified in the BMP Plan,the permittee must conduct an investigation to determine the cause of such exceedance. Whenever monitoring results exceed the upper action level for the period of time specified in the BMP Plan,the permittee must complete corrective action to bring the wastewater treatment system influent mass loading below the lower action level as soon as practicable. 3. Although exceedances of the action levels will not constitute violations of an NPDES permit,failure to take the actions required by Section E.2 as soon as practicable will be a permit violation. 4. The permittee must report to the Division the results of the daily monitoring conducted pursuant to Section E.1.Such reports must include a summary of the monitoring results,the number and dates of exceedances of the applicable action levels,and brief descriptions of any corrective actions taken to respond to such exceedances. Submission of such reports shall be annually,by March 31'of the following year. Section F. BMP Definitions 1. Action Level:A daily pollutant loading that when exceeded triggers investigative or corrective action. Mills determine action levels by a statistical analysis of six months of daily measurements collected at the mill.For example,the lower action level may be the 75th percentile of the running seven-day averages(that value exceeded by 25 percent of the running seven-day averages)and the upper action level may be the 90th percentile of the running seven-day averages(that value exceeded by 10 percent of the running seven-day averages). 2.
