• North American Datum (NAD): 1983
• Longitude (degrees, minutes, seconds): 78° 12' 10" W
• Latitude (degrees, minutes, seconds): 34° 21' 10"N
2.2 REGULATORY JURISDICTION
The Mill is under the jurisdiction of the following State and Federal agencies:
North Carolina Department of U.S. Environmental Protection Agency
Environmental Quality Region 4
Division of Water Resources—NPDES Unit Sam Nunn Atlanta Federal Center
Department of Water Resources 61 Forsyth Street, SW

Raleigh,North Carolina 27699-1617
2.3 MILL PROCESS DESCRIPTION
The primary product of the Mill is softwood pulp. Wood chips are cooked in either the Kamyr
continuous digester or one of the 16 batch digesters. The pulp slurry from each digester is blown
into a blow tank. From the blow tank, the pulp slurry is deknotted and washed in the brownstock
2-1
IP Riegelwood NPDES Renewal(1-24-23).docx 1/25/2023

INTERNATIONAL PAPER
International Paper—Riegelwood Mill
National Pollutant Discharge Elimination System Renewal Application
washers. After washing, pulp from the batch digesters goes through an oxygen delignification
stage before being screened and sent to Nos. 1 and 2 Bleach Plants. The pulp from the Kamyr
digester(sometimes blended with pulp from batch cooks) is washed, screened, and sent to No. 3
Bleach Plant.
Pulp is bleached with chlorine dioxide supplemented with other bleaching agents prior to being
sent to the two pulp dryers. Chlorine dioxide is generated with a methanol-based system.
Weak black liquor from the pulping process is stored in several process liquor tanks prior to
chemical recovery. In the recovery process,spent cooking chemicals are recovered by evaporating
water from the weak black liquor in multiple effect evaporator systems and concentrators. The
liquor is combusted in one of two recovery boilers. The resulting smelt is dissolved in weak wash
the smelt dissolving tanks. In the causticizing and lime recovery area, dissolved smelt (called
green liquor) is clarified and then mixed with lime (CaO) in the slaker to form white liquor and
lime mud in the causticizers. This white liquor/lime mud slurry is then clarified to separate the
white liquor from the lime mud. The white liquor is sent to the digesters and the lime mud is
conditioned,thickened, and processed in a lime kiln to regenerate CaO.
Other operations at the Mill include power boilers,pulp drying,a woodyard,wastewater treatment,
and other ancillary operations.
2.4 WASTEWATER TREATMENT DESCRIPTION
The Mill operates an aerated stabilization basin system to treat Mill process water, sanitary
wastewater, landfill leachate, and a portion of the Mill's stormwater. Additionally, two offsite
facilities send a small volume of stormwater to the Mill's wastewater treatement system. Process
wastewater, sanitary wastewater,and stormwater is sent to two primary clarifiers,where solids are
settled. Clarifier underflow sludge is either sent to one of three primary sludge ponds(Ponds 1,2,
and 3) for dewatering or to screw presses for mechanical dewatering and then to the power boilers
for use as fuel. The sludge ponds are periodically excavated, and sludge is sent to the landfill.

INTERNATIONAL 0 PAPER
International Paper—Riegelwood Mill
National Pollutant Discharge Elimination System Renewal Application
Effluent from the primary clarifiers and landfill leachate are routed to the New Bay via an earthen
channel for treatment under aeration. New Bay effluent flows by gravity to Theodorakis Pond,
then to the South Bay,then to North Bay prior to discharge to the Cape Fear River via Outfall 001.
Secondary sludge from the New Bay, the Theodorakis Settling Pond, and the South Bay is
periodically dredged and can be placed in one of the six sludge ponds(Ponds 1, 2, 3,A, B, and C).
Supernatant from Ponds 1, 2, and 3 discharges into the earthen channel leading into the New Bay.
Supernatant from Ponds A, B, and C discharges directly to the New Bay.
2.5 OUTFALL DESCRIPTIONS
The Mill has one permitted outfall for the discharge of treated wastewater, as well as two internal
outfalls.
External Outfall:
• Outfall 001 —Located on the northern side of the Mill in the North Lagoon. Outfall 001
discharges wastewater associated with all industrial operations, landfill leachate,
stormwater,and sanitary sewer wastewater. Outfall 001 consists of a Parshall Flume and
discharges wastewater to the Cape Fear River. The location of Outfall 001 is shown in
Figure B-1 in Appendix B.
Internal Outfalls:
• Outfall 004—consists of combined effluent from Bleach Plant 1 and Bleach Plant 2, and
discharges upstream of the bar screen for No. 1 Primary Clarifier.
• Outfall 005 — consists of effluent from Bleach Plant 3, and discharges upstream of the
bar screen for No. 1 Primary Clarifier.

3. REGULATORY AND PERMITTING BACKGROUND
The Mill is currently operating under NPDES permit number NC0003298 issued by NCDEQ with
an expiration date of July 31, 2023. In accordance with 15A North Carolina Administrative Code
(NCAC) Subchapter 2H .0106, a new permit application must be submitted 180 days before the
existing permit expires. Therefore,this permit application is being submitted prior to the February
1, 2023 deadline.
Under the current NPDES permit, the Mill discharges process wastewater, sanitary wastewater,
and some stormwater through one permitted outfall to the Cape Fear River. Additional stormwater
discharges are permitted separately under Stormwater NPDES Permit Number NCS000101.
Discharges of stormwater and treated wastewater are regulated by the NPDES program
administered by the NCDEQ. The NPDES program regulations applicable to the Mill are
referenced in 15A NCAC Subchapters 2B, 2H, 2T, and 8G.
The process wastewaters generated at the facility are regulated under the Effluent Guidelines and
Standards for the Pulp, Paper, and Paperboard Point Source Category at 40 CFR 430 Subpart B —
Bleached Papergrade Kraft and Soda Subcategory. The significant pollutants regulated by the pulp
and paper effluent guidelines include biochemical oxygen demand (BOD), total suspended solids
(TSS) and adsorbable organic halogens (AOX) for Outfall 001 and chloroform for Outfalls 004
and 005. Effluent limits derived from production pursuant to Subpart B are discussed in Section
4.1.
The Mill has certified that no chlorophenolic-containing biocides are being used onsite and is
exempt from pretreatment standards for Pentachlorphenol and Trichlorophenol under 40 CFR Part
430 Section 36 and 106.
The Mill certifies that per-and polyfluoroalkyl substances (PFAS) are not intentionally added or
used in the Mill's processes. The Mill did purchase and apply paperboard coatings in the past that
may have included PFAS. Manufacturing process water is sourced from a river intake located
downstream from Chemours. As a result, PFAS might be detectable in the Mill's fmal effluent.

Section 316(b) of the Clean Water Act imposes requirements on cooling water intake structures to
minimize environmental impacts due to the impingement of fish and shellfish on intake structures
and the entrainment of eggs and larvae through cooling water systems. Pursuant to 40 CFR
§125.91(a),cooling water intake structure requirements are applicable to existing facilities that use
one or more cooling water intake structures with a cumulative design intake flow of greater than
2 million gallons per day (MGD)to withdraw water from waters of the U.S. and 25% or more of
that water is used exclusively for cooling water purposes. The Mill withdraws more than 2 MGD
from the Cape Fear River. Less than 25%of the water withdrawn is used exclusively for cooling
purposes, thus the requirements of Section 316 b of the Clean Water Act regarding design and
q ( ) g g g
operation of cooling water intake structures do not apply to the Mill.

4.1 DERIVATION OF PERMIT LIMITS
The Mill is subject to effluent limitation guidelines (ELGs) under 40 CFR 430, Subpart B —
Bleached Papergrade Kraft and Soda (Subpart B). After historically producing both coated
paperboard and fluff/market pulp, the Mill underwent a full conversion to solely fluff and market
pulp in 2016. The best practicable control technology currently available (BPT) ELGs for
bleached kraft facilities where market pulp is produced are applied to annual average paper
production in air-dried tons per day(ADT/day), accounting for downtime,to determine the Mill's
technology-based effluent limits (TBELs) for BOD and TSS on a mass basis (pounds per day,

lb/day) (Table 4-2). The current TBEL for TSS is based on the BPT ELGs for bleached kraft
facilities where pulp and fine papers are produced; this category is no longer representative of the
Mill's production. Utilizing the ELGs for bleached kraft facilities where market pulp is produced,
which are representative of the Mill's current production, results in an increase in the Mill's
TBELs.

The best available technology economically achievable(BAT)ELGs for fiber lines that do not use
an exclusively total chlorine free (TCF) bleaching process, shown in Table 4-3 below, are applied
to unbleached pulp fed to the bleach plant in ADT/day to determine the Mill's technology-based
AOX and chloroform discharge limitations on a mass basis (pounds per day, lbs/day).

The Mill reviewed annual production data for the past five calendar years to determine the
production rate to be used for projecting technology-based discharge limitations. The annual
average ADT/day for the pulp machines and bleach plants is provided in Table 4-4 below. Pulp
machine production is presented in gross reel tons. Bleach plant production is presented as
unbleached pulp fed to the bleach plants. The highest annual average production of market pulp
in the last five years was 2,211 ADT/day in 2018. The highest rate of unbleached pulp fed to the
bleach plants in the last five years was 2,160 ADT/day in 2018 (1,123 ADT/day for Bleach Plants

Analytical laboratory data is included in Appendix C. Sampling was performed on May 25, 2022
for Outfall 001. The samples were analyzed by Environmental Chemists, Inc. In addition,
Discharge Monitoring Report (DMR) data from November 2020 — October 2022 was used to
supplement the lab analytical data.
In addition to the pollutants listed on Form 2C, as required by Session Law 2018-5, Senate Bill
99,Section 13.1(r),the Mill has reviewed the list of pollutants for which there are certified methods
found at 40 CFR Part 136 and considered whether any pollutants listed at 40 CFR Part 136 that
are not listed at Form 2C would be anticipated to the present in the Mill's discharge. The Mill
reviewed the list of pollutants against Safety Data Sheets (SDSs) for chemicals used at the Mill
and consulted with the National Council for Air and Stream Improvement (NCASI). As a result
of this review, the Mill conducted additional sampling on December 16, 2022, and samples were
analyzed for additional chemicals listed at 40 CFR Part 136 that are not listed at Form 2C. The
results for parameters that were detected in the Mill's effluent are provided in the Chemical
Addendum Form in Appendix A. The laboratory report is provided in Appendix C.

6. PROPOSED PERMIT REVISIONS
As part of the NPDES renewal application process, the Mill has reviewed the existing permit and
is requesting the following revisions.
6.1 SUMMER MONTHS
In 1992, the Mill requested a variance from the Environmental Management Commission to
redefine the summer period. The Environmental Management Commission granted a variance
request, and the summer period for the Mill is defined as June 1 — October 31. IP requests
continuation of the variance with this renewal.
6.2 AOX AND TSS MONITORING FREQUENCY
The Mill is requesting a reduction in required monitoringfrequencies for AOX and TSS at Outfall
q g q q
001. All parameters have been evaluated according to the U.S. EPA Interim Guidance for
Performance-Based Reduction of NPDES Permit Monitoring Frequencies issued in April 1996
(U.S. EPA Interim Guidance), as discussed in the following subsections.
6.2.1 AOX Monitoring Frequency
40 CFR §430.2(b)(1) allows a reduction in monitoring frequency for effluent limitations
representing the degree of effluent reduction attainable by the application of best available
technology economically achievable(BAT)after five years. The Mill's AOX limits are BAT,and
the Mill has been compliant with the AOX limits for more than five years. Additionally,the U.S.
EPA Interim Guidance supports a reduction in monitoring frequency based on the Mill's margin
of compliance with the current limit and the consistency of the Mill's monitoring data. Table 6-1
below summarizes the statistical evaluation of the Mill's AOX data over the past two years. Table
3 of the U.S. EPA Interim Guidance,which corresponds to a dataset with a coefficient of variation
of 20%, supports that the probability of reporting a monthly average permit limit violation for four
samples per month(approximately one per week) is 0%based on the ratio of the Mill's long term
average to the monthly average permit limit.

6.3 CHRONIC TOXICITY TESTING REQUIREMENT
As noted in Section 4, the Mill is currently required to conduct chronic toxicity testing for
Ceriodaphnia dubia once per quarter. This Mill has consistently passed the quarterly toxicity
tests and requests to reduce the frequency to semiannually. 15A NCAC 02B .0508(d) requires
toxicity limits and monitoring requirements for dischargers in the "Paper and Allied Products"
standard industrial group, which includes the Mill. 15A NCAC 02B .0508(d)(3) states that
"Toxicity limits shall be applied to all major discharges and all discharges of complex
wastewater...Specific frequency shall be defined by individual permit conditions." IP understands
the applicable regulations to allow for NCDEQ's discretion to make a case-by-case determination
on the testing frequency. Based on the Mill's consistent history of passing the chronic toxicity
tests, a reduction in testing frequency presents little or no risk of a reduction in water quality of
the receiving stream. The Mill respectfully requests to reduce the monitoring frequency to
semiannual.
6.4 OUTFALL 004 AND 005 SAMPLE COLLECTION PERIOD
The Mill is required to collect samples from Outfalls 004 and 005 once per quarter to analyze for
chloroform, chlorinated phenolic compounds, and dioxin compounds. Section A.(2.)2 of the
current NPDES permit requires that the Mill collect separate grab samples every 4-hours for a 24-

hour period, in accordance with U.S. EPA's Appendix B sample collection methods. Complying
with this condition requires Mill personnel to collect samples during nighttime conditions, outside
of their normal job hours and job area. The Mill has concerns about the safety of this practice and
requests to collect grab samples every 4-hours for a 12-hour period rather than over a 24-hour
period. Other state agencies, including the Georgia Environmental Protection Division (GEPD)
and the South Carolina Department of Health and Environmental Control (SCDHEC), have
approved exceptions to U.S. EPA's Appendix B sample collection methods for similar facilities.
Further, the Mill has a consistent history of complying with the discharge limits for Outfalls 004
and 005. The Mill requests that NCDEQ approve a similar exception to the prescribed sample
collection methods.
6.5 FISH TISSUE DIOXIN MONITORING
Section A.(7.)of the Mill's current NPDES permit requires the Mill to conduct a fish tissue dioxin
study once per permit term. The Mill's fish tissue dioxin study results have been consistent over
several permit terms, and the Mill requests to remove this requirement from the permit.
