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. 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: NC DEQ/Division of Water Resources/Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh,North Carolina 27699-1617 See"How to Request a Waiver from Electronic Reporting"section below.
