Subject: Draft NPDES Permit NC0030406
Town of River Bend WWTP
Grade II Biological WPCS
Craven County
Attached with this letter is a copy of the Draft NPDES permit renewal for the Town's WWTP. Please
review this draft carefully to ensure a thorough understanding of the requirements and conditions it
contains. There are a few changes in the draft attached here from the existing permit. These changes and
other considerations are summarized below.
• Regulatory Citations - Language has been added where necessary in the permit to provide regulatory
citations for permit requirements. This includes updates to citations that have been changed with
recent rule revisions.
• Electronic Reporting - Permit language has been modified to be consistent with the finalization of
federal requirements for electronic reporting.
• Updates to Footnotes on Effluent Table — Language in the footnotes has been updated to be consistent
with our current descriptions.
• Footnote 5 referencing compliance with a Total Nitrogen (TN) Load limit and previous Special
Condition A.(3.) have been removed since the facility does not currently have TN load limit. Please
continue to work to minimize nutrient loading as nutrient limits may be applicable in the future.
• Nutrient Management Re -Opener — A Special Condition [A.(5.)] has been added to the permit to
address re -opening of the permit for the potential inclusion of additional nutrient control
requirements.
• Map Update — Permit map information has been updated.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in this
draft document (cover, map, and Part I). The conditions are the same as in your current permit. The latest
version of the standard conditions is available at https://bit.ly/3k5NFaL and can be viewed online or
downloaded as a PDF file.

A. (2.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S. 143-215.1(b)]
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (lb/mo) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/L) of the composite samples
collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the appropriate discharge monitoring
report for each month and shall report each year's results (lb/yr) with the December report for that year.
A. (3.) TOTAL NITROGEN ALLOCATIONS
[G.S. 143-215.1(b)]
a. The following table lists the Total Nitrogen (TN) allocation(s) assigned to, acquired by, or transferred to the
Permittee in accordance with the Neuse River nutrient management rule (15A NCAC 02B .0713) and the
status of each as of permit issuance. For compliance purposes, this table does not supersede any TN limit(s)
established elsewhere in this permit or in the NPDES permit of a compliance association of which the
Permittee is a Co-Permittee Member.

Permit NCO030406
If the result of the mercury analysis is not provided with the application, the application may be returned as
incomplete and the Permittee considered non -compliant.
A. (5.) PERMIT RE -OPENER: NUTRIENT MANAGEMENT
[NCGS 143-215.1 (b)]
a) Pursuant to N.C. General Statues Section 143-215.1 and implementing rules found in Title 15A of
North Carolina Administrative Code, Subchapter 02H, specifically, 15A NCAC 02H.0112(b)(1) and
02H.0114(a), and Part II, Sections B.12 and B.13. of this Permit, the Director of DWR may reopen
this permit to require nutrient management measures for the discharge. The results of water quality
monitoring, modelling or other evaluations may require that conditions for total nitrogen and total
phosphorus control be imposed on this permit.
b) The Division may, upon written notification to the permittee, re -open this permit in order to
incorporate or modify effluent limits, monitoring and reporting requirements, and other permit
conditions when it deems such action is necessary to implement TMDL(s) approved by the USEPA.
A. (6.) 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.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: hgps://deq.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the following address:

NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. Regardless of the submission method, the first DMR is due on the last
day of the month following the issuance of the permit or in the case of a new facility, on the last day
of the month following the commencement of discharge.
Starting on December 21, 2025, the permittee must electronically report the following compliance
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.
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 Electronic
Reporting Rule is found at:
https://www.federalre ig ster.gov/documents/20l5/lO/22/2015-24954/national-pollutant-discharge-
elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty (60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary
waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports
Page 6 of 8

Permit NCO030406
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:
http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section
B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting
purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North Carolina's
eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following
web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION
WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or persons
who manage the system, or those persons directly responsible for gathering the information, the
information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am
aware that there are significant penalties for submitting false information, including the possibility of
fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)1
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions.
