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: NC DEQ/Division of Water Resources/Water QualityPermittingSection 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 Electronic Reporting"section below.

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- electronicreporting-rule.
