2. Upstream: at least 100 feet upstream from the outfall. Downstream: at least 300 feet downstream from the
outfall.
3. See Section A. (3) for instructions should the facility's permitted UV system fail and an alternate means of
disinfection is required.Total Residual Chlorine monitoring requirements and limits are applicable if chlorine
compounds are used for disinfection
All samples collected should be from a representative discharge event.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRAC
AMOUNTS.
A. (2.) NUTRIENT REDUCTION REQUIREMENT
[NCGS 143-215.1 (b)]
Dischargers to the Tar-Pamlico River are subject to the requirements, terms and conditions, of the Tar-
Pamlico Nutrient Sensitive Waters Implementation Strategy: Phase IV adopted July 9, 2015. Non-
members of the Tar-Pamlico Association (Association) will maintain or receive permit effluent limits for
Total Nitrogen and for Total Phosphorus concentrations as defined in the Strategy. Any revisions to the
Strategy during the life of this permit are applicable.
If requirements other than those listed in this permit are adopted as part of a revision of the Strategy, the
Division reserves the right to reopen this permit to include these requirements.
A. (3.) TEMPORARY MEANS OF DISINFECTION
[NCGS 143-215.1 (a)]
In the event that the wastewater treatment plant's ultraviolet(UV) disinfection system should fail,
underperform, or otherwise be removed from effective service, the permittee or his agent should
immediately inform the Surface Water Protection Section staff of the Raleigh Regional Office of this
development and discuss temporary, alternate means for disinfection of the effluent.
If chlorine compounds are used as temporary means of disinfection, the total residual chlorine (TRC)
concentration of the effluent must be monitored on a daily basis while this method of disinfection is in
use and values must be reported on the discharge monitoring report. TRC in the effluent may not
exceed 17 ug/L; therefore, dechlorination methods may also be necessary to ensure protection of water
quality in the receiving stream.
In the event that TRC monitoring should occur, the Division shall consider all effluent TRC values
reported below 50 µg/L to be in compliance with the permit. However, the Penuittee shall continue to
record and submit all values reported by a North Carolina certified laboratory(including field certified),
even if these values fall below 50 pig/L.
Use of a disinfection system other than the permitted UV system during circumstances not deemed as
emergency and/or temporary(replacement of lamps, lamp cleaning or maintenance, etc.) will be
considered a violation of the terms of this permit.

A. (4.) ELECTRONIC REPORTING—DISCHARGE MONITORING REPORTS
[NCGS 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: 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.
Page 5 of 7

NPDES Permit NC0038644
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.federalregister.gov/documents/2015/10/22/2015-
24954/national-pollutant-di scharge-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
