NPDES Electronic Reporting Rule

EPA’s Electronic Reporting Rule, modernizes reporting for municipalities, industries and other facilities that hold National Pollutantnetdmrlogo.jpg Discharge Elimination System permits.
 

The rule requires NPDES permit holders to report information electronically, instead of filing written paper reports. Oregon adopted EPA's two-phased approach, described below:

  • Phase 1
    This phase includes Discharge Monitoring Reports and the Sewage/Sludge Biosolids annual program reports.
  • Phase 2
    This phase includes General Permit Reports, Concentrated Animal Feeding Operation Annual Program Reports, Municipal Separate Storm Sewer System Program Reports, Pretreatment Program Reports, Significant Industrial User Compliance Reports in Municipalities Without Approved Pretreatment Programs, Sewer Overflow/Bypass Event Reports, and CWA 316(b) Annual Reports. Per the EPA, electronic reporting of Phase 2 data groups must be fully implemented by Dec. 21, 2025.

The rule does not change what information is required. It only changes the method by which information is provided: electronic rather than paper-based.

NetDMR: EPA’s eReporting tool for Oregon NPDES permit holders

EPA has developed an electronic, web-based reporting tool for NPDES permit data called NetDMR. NetDMR requires:

  • A computer
  • An internet browser
  • High-speed access to the Internet (i.e., DSL, fiber optic)
  • CDX test site
  • CDX production site
    NetDMR can be accessed through the Oregon DEQ instance of the NetDMR program service.

Oregon’s implementation plan

EPA and DEQ require holders of individual NPDES permits and dischargers authorized under general NPDES permits to submit discharge monitoring reports (DMRs) electronically in accordance with the following timelines: 

DEQ may grant a waiver that allows a permitted facility to submit physical reports to meet requirements of its NPDES permit.

You can contact DEQ using our NetDMR Support Line at 503-229-6400 or by email at NetDMR support staff

The “eReporting” rule and use of EPA’s NetDMR reporting tool will:

  • Save time and resources for permittees, DEQ, EPA and other permitting authorities.

  • Increase data accuracy and reduce potential for submitting errors.

  • Provide greater clarity on who is and who is not in compliance.

  • Enhance transparency by providing a timelier, complete, more accurate, and nationally-consistent set of data about the NPDES program.

  • Provide EPA and DEQ the ability to strategically address the most serious water pollution problems while using limited resources efficiently.​
