Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement

There are several changes from the existing permit, including the following:
• Added Stream Index Code, HUC Code, and Subbasin Code to the Supplement to Permit Cover
Sheet.
• Added the facility grade to Section A. (1.).
• Updated the effluent table in Section A. (1.) with eDMR parameter codes.
• Added effluent monitoring for turbidity to the table in Section A. (1.) to determine compliance

compliance with 15A NCAC 02B.0211 (18) for Trout waters.

Permit NCO032123
A. (2.) TEMPORARY MEANS OF DISINFECTION
[NCGS 143-215.1(b)]
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 Winston-Salem 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 daily 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 28
µg/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 Permittee 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 µg/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. (3.) ELECTRONIC REPORTING OF 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.)
• Section D. (6.)
• Section E. (5.)
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)l
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.
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 s�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:

(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:

5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These
records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may
