Dear Mr. Summerlin:

Subject: Draft NPDES Permit NC0021903
Town of Warsaw WWTP
Grade III Biological WPCS
Duplin County
Attached with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review
this draft carefully to ensure thorough understanding of the requirements and conditions it contains We
understand from your renewal application and subsequent additional information submittals that the
WWTP currently has improvement projects under construction. These improvements are authorized
under two Authorizations to Construct — one from October 3, 2019 scheduled for completion in June
2022, and the second from September 1, 2021 scheduled for completion in March 2023. There are a few
changes in the draft from the existing permit. These changes are summarized below.
• Regulatory Citations - Language has been added where necessary in the permit to provide regulatory
citations for permit requirements.
• Electronic Reporting - Permit language has been modified to be consistent with the finalization of
federal requirements for electronic reporting.
• Treatment System Components — The treatment system components on the Supplement to Cover
Sheet have been updated to reflect the sizing of the oxidation ditches as 457,500 gallons each as noted
in narrative information provided in the renewal application.
• Nutrient Reopener Language — This language has been updated in the permit.
• Map Updates— The permit map has been updated to include more descriptive information.
• Compliance Schedule for Pretreatment Program — The renewal review process has revealed the need
for the Town of Warsaw to develop and implement a pretreatment program. This requirement is
established through a Compliance Schedule that has been added as Section A.(4) in the permit. The
pretreatment program is required based on the apparent existence of a current Significant Industrial
User (SIU) discharging to your system as well as the anticipated connection of another SIU that is
currently under construction. Your adherence to the Compliance Schedule is required for you to
come into compliance with your permit and applicable pretreatment rules. Please note that

connection of any new SIUs is contingent upon the Town developing and implementing your
pretreatment program as required.
In a previous email on April 5, 2022 I forwarded you and your consultants information on the process
in developing your pretreatment program. I also provided contact information for staff in the
Pretreatment Program of our Municipal Permitting Unit in case you have questions about this
process. Staff in the Pretreatment Program will be contacting the existing SIU discharging to your
system to make them aware of the draft permit and schedule for development of local permit
conditions for their discharge.
In your application you had asked for reduction in monitoring frequencies for four parameters. We have
reviewed this request, and while your current monitoring data could potentially support this change, the
Division has determined that the additional data will be helpful in assessing issues related to your
implementation of a pretreatment program. For this reason, the monitoring frequencies will be
maintained in this permit. You may request a review of this issue after you have established your
pretreatment program.
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.
Concurrent with this notification the Division is publishing a notice in a newspaper having general
circulation in the Duplin County area soliciting public comments on this draft permit and your
requirement to complete a pretreatment program under 15A NCAC 02H .0906. Please provide any
written comments you may have to me no later than 30 days after receipt of this draft permit
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning this draft permit,
please call me at [phone] or contact me by email at [e-mail]. At this time,
contact by email is the most effective method. If we need to set up a call to discuss any issues, we can set
that up through email.
Sincerely,

II of this permit
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:
https://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.

Draft Permit NC0021903
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:
http s://www. federalregister. gov/documents/2015/10/22/2015 -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 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. (11.)(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:
