Dear Mr. Lynch:
The Division of Water Resources staff has reviewed your August 10, 2121, request for
modification of the Neuse River RRF's NPDES permit to the City's pending purchase of
nitrogen allocation from International Paper, Inc.We have also reviewed the company's request
to modify its New Bern Mill's permit to reflect the allocation purchase. The Division has made a
tentative determination to modify both permits as requested and is forwarding herewith,for
your review and comment, the draft permit with revisions to Special Conditions A.(1.), Effluent
Limitations and Monitoring Requirements, and A.(6.), Total Nitrogen Allocations.
At this time,we are submitting a notice for publication in the newspapers of general circulation
in Wake County,inviting public comment on the draft permit modification. The notice is
scheduled to be published on or about October 15, 2021. Following a 30-day comment period,
the Division will review all pertinent comments received and take appropriate action on the
permit modification.
Please provide any comments you have regarding the draft permit to this office,in writing,
no later than Monday,November 15,2021. Comments should be sent to my attention at either
NCDEQ/ DWR, WQ Permitting Section, 1617 Mail Service Center, Raleigh, NC, 27699-1617;or
at [e-mail].
The proposed modifications affects Conditions A.(1.), Effluent Limitations and Monitoring
Requirements, and A.(6.),Total Nitrogen Allocations,of the permit and includes the following
changes:
• The purchase of 13,000 lb/yr delivered (estuary) nitrogen allocation from International
Paper has been entered in the table of allocations in Condition A.(6.),and the total
allocation has been increased accordingly;
• The NRRRF's TN Load limit in Condition A.(1.) has been increased to reflect the new
total allocation.

subject to additional toxicitytestingrequirements specified in Federal Regulation 40 CFR 122.21(j)(5).
q p
The US EPA requires four (4) toxicity tests for a test organism other than the test species currently
required in this permit. The multiple species tests should be conducted either quarterly for a 12-month
period prior to submittal of the permit renewal application,or four tests performed at least annually in
the four and one half year period prior to the application. These tests shall be performed for acute or
chronic toxicity,whichever is specified in this permit. The multiple species toxicity test results shall be
filed with the Aquatic Toxicology Branch at the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Or,results can be sent to the email,[e-mail].
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E
(Toxicity Testing Data) of EPA Municipal Application Form 2A,when submitting the permit renewal
application to the NPDES Permitting Unit.
A.(9.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21,2015.
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):

monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports;and
• Clean Water Act(CWA)Section 316(b) Annual Reports.
NPDES Electronic Reporting Rule-Phase 2 Extension. EPA is proposing to extend the Phase 2
deadline from December 21,2020,to December 21, 2023. The current compliance date will be
extended if the implementation date is extended as a final regulation change in the federal register.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated
entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES

temporary waiver shall not exceed 5 years and shall thereupon expire. At such time,monitoring
data and reports shall be submitted electronically to the Division unless the permittee re-applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver
request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:

NPDES Fact Sheet - Addendum
Neuse River Resource Recovery Facility
NC0029033, Major Modification
October 12,2021
1. SCOPE
This Fact Sheet is limited to the scope of the permit modification described below. For additional
other requirements of itspermit,refer to theJune 17,2020
information regarding the facility and q ,
Fact Sheet.
2. PROPOSED PERMIT ACTION
2021, the Cityof Raleigh requested modification of the permit to
By its letter of August 10, g q subject
reflect its purchase of Total Nitrogen(TN) allocation from the International Paper, Inc., New Bern
Mill, NC0003191,and to increase its annual TN Load limit accordingly.
By its letter of September 9, 2021, International Paper,Inc.,requested modification of its own permit
to reflect its sale of TN allocation and to make the equivalent reduction in its TN Load limit.
The Division has reviewed the requests and supporting materials and has made a tentative
determination to modify both permits,as requested,in simultaneous permit actions.
3. WATER QUALITY-BASED EFFLUENT LIMITATIONS (WQBELs)
The Neuse River Nutrient Strategy Wastewater Discharge Requirements, 15A NCAC 02B .0713,
assigned Total Nitrogen allocations to nutrient-bearing NPDES dischargers according to the size
and type of discharge. The amount of allocation held by a discharger determines its TN Load limit.
The Strategy allows the transfer of TN allocations among NPDES dischargers provided there is no
net increase in the point source nitrogen load to the Neuse estuary. To achieve this end, transfers
are conducted in terms of delivered (estuary) TN Loads,not discharge (end-of-pipe) loads.
Transport factors assigned to each discharger are used to convert delivered loads to the equivalent
discharge loads,and back again.
Purchase of TN Allocation
Raleigh's Neuse River facility currently holds 687,373 lb/yr of TN discharge allocation. The facility
was assigned a transport factor of 50%,meaning that half of its TN discharge is expected to reach
the Neuse estuary, and its estuary (delivered) allocation is 356,687 lb/yr. Raleigh purchased 13,000
lb/yr of delivered TN allocation from International Paper, Inc. This translates to 26,000 lb/yr at the
Neuse River facility's discharge.
Technology-Based TN Load Cap
The Neuse Strategy requires that new and expanding facilities acquire sufficient TN allocations' for
their discharges. To ensure each facility provides a reasonable degree of nitrogen removal,the
Strategy imposes a technology-based effluent limitation (TBEL),or cap,on its TN discharge
equivalent to 3.5 mg/L TN at full permitted flow.The facility's discharge cannot exceed the amount
of allocation or credits it holds (WQBEL),or the TN cap (TBEL),whichever is less.
Raleigh expanded the NRRRF from 60.0 to 75.0 MGD in 2018. Its technology-based cap at the
higher flow is 3.5 mg/L * 75 MGD * 8.34 * 365 days/year,or 799,076 lb/yr at the discharge. With
this purchase from International Paper, its TN holdings increase to 713,373 lb/yr. Because this is
less than its technology-based cap,all of the facility's newly acquired allocation can be applied
1 Permittees may also purchase Nutrient Offset Credits,if available.Credits are not a factor in this case.

toward its TN Load limit. The increased TN Load limit is consistent with the Neuse Nitrogen
TMDL and so is protective of water quality; therefore, the increased limit is consistent with the
state's antidegradation policy.
4. PERMIT REVISIONS
Raleigh's draft permit includes two changes:
• The 13,000 lb/yr of delivered TN allocation purchased from International Paper, Inc., and the
equivalent 26,000 lb/yr of discharge allocation have been added to the allocation table in
Condition A.(6.). These qualify as Active allocation,so the total Active allocation is increased to
713,373 lb/yr at the discharge,or 356,687 lb/yr at the estuary.
• The TN Load limit in Condition A.(1.) has been increased to 713,373 lb/yr to reflect the facility's
new total Active allocation.
5. PUBLIC NOTICE SCHEDULE
The Division plans to have public notice for the draft permit to be published on or about October
15,2021.
Per 15A NCAC 2H .0109& .0111,the Division will accept comments for a period of 30 days
following the publication date of the public notice. Any request for a public hearing must be
submitted to the Director within the 30-day comment period and must indicate the interest of the
party filing such request and the reasons why a hearing is warranted.
6. DIVISION/STAFF CONTACT
Questions regarding the above information or draft permit can be directed to Mike Templeton at
