(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[Supersedes Section D.(2.)and Section E.(5.)(a)!
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 complete the eDMR
submission by printing, signing,and submitting one signed original and a copy of the computer printed eDMR to
the following address:

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.
Page 4 of 6

Permit NC0050661
Duplicate signed copies shall be submitted to the mailing address above. See"How to Request a Waiver from

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;

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:
http://www2.epa.gov/compliance/final-national-pollutant-discharge-elimination-system-npdes-

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

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:
