Permit NCO032212
A. (3.) 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 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 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 26 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 jzg/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 jig/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 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 Pennits):
• 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.) (all
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.
Until such time that the state's eDMR application is compliant with EPA's Cross -Media
Electronic Reporting Regulation (CROMERR), permittees will be required to submit all
discharge monitoring data to the state electronically using eDMR and will be required to
Page 5 of 8

Permit NCO032212
complete the eDMR submission by printing, signing, and submitting one signed original
and a copy of the computer printed eDMR to the following address:
NC DENR / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
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 mailing address above. 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, 2020, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;

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:

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:

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

shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
U 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

• Section A. (4.) has been updated to require electronic submission of
effluent data reports (DMRs). Federal regulations require electronic
submittal of all discharge monitoring.
• An updated outfall map has been included.
• Monitoring for turbidity has been added to determine compliance with 15A
NCAC 0213.0211 (21).
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 1). The conditions are the same as in your current permit except that agency and
