2. U: upstream at least 50 feet from the outfall. Downstream at least 100 feet from the outfall.
There shall be no discharge offloating solids or visible foam in other than trace amounts.
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
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
Page 3 of 6

Permit NC0067024
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

permit(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting

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

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

initial recipient for the electronic submission.

(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)].
_ EP„ .plans to establish a website that will also link to theapopriate-electronic reporting tool for _
—a each-type of electronic submission and for each sfae.`Instructions on howo access and use the —

Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-

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

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:

reporting purposes.
For eDMR submissions,the person signing and submitting the DMR must obtain an eDMR user
