A. (3.) TEMPORARY MEANS OF DISINFECTION
[NCGS 143-215.1 (a)]

service,the permittee must immediately notify the Regional Water Quality Operations staff of the Asheville
Regional Office and discuss temporary,alternate means for disinfection of the effluent.
If chlorine compounds are used as a temporary means of disinfection,the total residual chlorine(TRC)
concentration of the effluent must be monitored on a daily basis and values reported on the discharge monitoring
report. TRC in the effluent may not exceed 28 µg/L;therefore,dechlorination methods may also be necessary.
Use of a disinfection system other than that approved by this Division during circumstances not deemed as
emergency and/or temporary(e.g.,replacement of UV lamps, cleaning and maintenance,etc.)may be considered
a violation of the terms of this permit.

Reporting Requirements[Supersedes Section D. (2.)and Section E. (5.)(ail
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 intemet. 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:

Permit NC0088943
Grade II Biological Water Pollution Control System[15A NCAC 08G.0302]
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).
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-discharge-elimination-
system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the"Reporting Requirements"section above.
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:
