Stormwater Electronic Data Monitoring Reports (eDMR)

EPA’s NPDES Electronic Reporting Rule requires all NPDES-permitted facilities to submit reports such as data monitoring reports and annual reports electronically rather than in paper. The rule changes only the method by which information is provided, not the content of the information that must be provided. 

Please visit the Wastewater eDMR web site if you need information about electronic reporting for an NPDES wastewater permit.

Benefits of eDMR

  • Saves time and resources by eliminating paper reports.
  • Provides a complete and accurate set of monitoring data on industrial facilities. This data can be used to update industrial permits going forward.
  • Brings DEQ and permittees into compliance with EPA’s NPDES Electronic Reporting Rule.


The Stormwater Program has begun bringing NPDES Stormwater Industrial permittees into eDMR between now and January 1, 2022.  NPDES Stormwater Industrial permit owners are required to complete Steps 1 and 2 of the Six Step Process by the following dates (in accordance with their permit types). 

If an industrial owner holds permits in two or more groups, then the earliest due date for Steps 1 and 2 will apply.  For example, an owner with coverage under an NCG020000 and an NCG140000 is required to complete Steps 1 and 2 by January 1, 2022.

If your industrial facility is not required to report analytical samples and does not foresee a need to do so in the near future, then you do not have to register for e-DMR.
