• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports

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.
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
