Dear Permittee:

Subject: Draft of NPDES NCO026816
Roseboro WWTP
Class WW-3
Sampson County
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure a
thorough understanding of the information, conditions, and requirements it contains.
This draft contains the following major changes from the existing permit:
• The Flow limit in Section A. (1.) has been increased to 0.70 following Division expansion procedures.
• Ammonia Nitrogen winter and summer limits have been added to Section A. (1.). Ammonia limits will
not take effect until 2030 to allow for operational changes at the W WTP so that the limits can be met.
• Due to the new flow limit, the facility has been reclassified to W W-3. Grade and citation has been added
to Section A. (1.).
• Please review the monitoring frequencies in Section A. (1.) as they have been updated to meet the
requirements of WW-3 facility.
• The parameters of Total Kjeldahl Nitrogen and Nitrate + Nitrite Nitrogen have been added to Section A.
(1.). Total Nitrogen sample type has been changed to calculated. A footnote has been added.
• Whole Effluent Toxicity (WET) testing has been removed from the permit as this facility no longer
receives complex wastewater (wastewater containing anything other than domestic waste) per the
permittee. If this facility accepts non -domestic wastewater (such as industrial) in the future, it is the
responsibility of the permit holder to inform the Division of the change. WET testing will be
reinstated at that time.
• Section A. (3.) has been updated regarding electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports (DMRs).
The NPDES standard conditions (Parts II, III, and M 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 except that agency and
division names have been updated. The latest version is available at httos://bit.ly/3k5NFaL and can be viewed
online or downloaded as a PDF file.
With this notification, the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Sampson County area, per EPA requirements. Please provide your
comments, if any, to me no later than 30 days after receiving this draft permit.

certified laboratory (including field certified), even if these values fall below 50 µg/l.
5. For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total
Kjeldahl Nitrogen, and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively.

A. (2) PERMIT RE -OPENER: SUPPLEMENTARY NUTRIENT MONITORING
[NCGS 143-215.1 (b)]
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in the North

and B-13 of this permit, the Director of DWR may reopen this permit to require supplemental nutrient
monitoring of the discharge. The purpose of the additional monitoring will be to support water quality
modeling efforts within the Cape Fear River Basin and shall be consistent with a monitoring plan
developed jointly by the Division and affected stakeholders. In addition, the results of water quality
modeling may require that limits for total nitrogen and total phosphorus be imposed in this permit upon
renewal.
A. (3) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS
[G.S. 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program

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.)
• Section D. (6.)
• Section E. (5.)
Reporting
Records Retention
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: htti)s://deQ.nc.gov/about/divisionstwater-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
Page 4 of 6

NPDES Permit NC0026816
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: httys://www.federalregister.gov/documents/2015/10/22/2015-
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
Page 5 of 6

NPDES Permit NC0026816
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:
httD://deo.ne.eov/about/divisions/water-resources/edmr
4. Sienatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)
