Subject: Draft NPDES Permit
Permit NC0003191
New Bern Mill
Craven County
Facility Class IV
Dear Mr. Meyer:
Enclosed with this letter is a copy of the Draft Permit for your facility. Please review the draft 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:
• The instream monitoring frequency (April 1 —October 31) for Dissolved Oxygen,Temperature,
pH, Conductivity,TN,and TP was reduced from 2/Month to Monthly based on the review of
the instream data and in response to the permittee's request.
• Quarterly PFAS monitoring was added to Outfall 001 based on the EPA Guidance.
• Limits for Chloroform,AOX,Pentachlorophenol, and Trichlorophenol were recalculated based
on the current production level.
• The Division is unable to grant permittee's request for removing concentration-based BOD5
limits because these limits are based on the water quality modeling and designed to protect
instream DO standard.
• The Division is unable to grant permittee's request for changing Grade of the wastewater
treatment system. The current Grade is based on the state rules and consistent with other pulp
1 and paper plants in North Carolina.

[G.S. 143-215.66]
The facility will calculate the daily Neuse River flow at Outfall 001 and must maintain this data onsite
and available to the Division for review upon request.
A. (12.)BEST MANAGEMENT PRACTICES (BMPs)
[G.S. 143-215.1(b)]
The permittee must implement the BMPs specified in Section I 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 I. 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 establish 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

Permit NC0003191
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 establish 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 establish 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
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 V.
Section II. BMP Plan Requirements
1. The permittee must prepare 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 I, construction of the mill
determines what 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 V.The BMP Plan also must specify the period of time that the mill
13 of 23

Permit NC0003191
determines the action levels established under Section IV may be exceeded without triggering the
responses specified in Section V.
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 II.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 significantly reduce 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
regulation. The permittee is not required to obtain approval from the Division of the BMP Plan or
any amendments thereto.
Section III. 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 III.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
I; (ii) Records of initial and refresher training conducted in accordance with Section I; (iii) Reports
prepared in accordance with Section I; and(iv) Records of monitoring required by Sections I and V.
14 of 23

Permit NC0003191
Section IV. Establishment of Wastewater Treatment System Influent Action Levels
1. The permittee must conduct a monitoring program per Section IV.2, for the purpose of defining
wastewater treatment system influent characteristics (or action levels), described in Section IV.3,
that will trigger requirements to initiate investigations on BMP effectiveness and to take corrective
action.
2. The permittee must employ the following procedures to develop the action levels required by Section
IV:
• 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) 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
initial action levels based on the results of that program.
specified in Section IV and must establishp gr
P
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 V,and an upper action level,which if exceeded will trigger the corrective action
requirements described in Section V.
4. The permittee must complete a second six-month monitoring program using the procedures specified
in Section IV 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.
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 V. 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 IV for the purpose of detecting leaks and spills,
tracking the effectiveness of the BMPs, and detecting trends in spent pulping liquor losses.
2. Whenever monitoring results exceed the lower action level for the time period 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 V.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 V.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 St of the
following year.
