Water Quality Permits

EPA’s Electronic Reporting Rule, modernizes reporting for municipalities, industries and other facilities that hold National Pollutant Discharge Elimination System – or “NPDES” – 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 I
    This phase will include Discharge Monitoring Reports and the Sewage/Sludge Biosolids annual program reports.
  • Phase II
    This phase will begin just before the conclusion of Phase I and will include 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 II data groups must be fully implemented by Dec. 21, 2020. Updates on this phase will be available on this web page.

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 Oregon 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:

Permit Type ​eReporting Timeline
​Individual major NPDES permits ​Permittees are reporting electronically already
​Individual minor NPDES permits

​Permittees must register and begin submitting DMRs:

  • In NetDMR Test by April 1, 2019.
  • In NetDMR Production by Sept. 1, 2019 (enforceable compliance deadline).
​General NPDES permits (including stormwater permits) ​Permittees are expected to begin transitioning to electronic reporting by the third quarter of 2019. Additional implementation details for general permits will be provided on this site.

​Holders of individual minor NPDES permits currently are eligible to begin submitting DMRs using NetDMR Test; however, DEQ is finalizing database coding for some permits. As DEQ completes permit setups, staff will send outreach packets to permit holders with instructions for accessing and using NetDMR. DEQ staff will be available to help permit holders navigate their permit and DMR setup in NetDMR.

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

DEQ Discharge Monitoring Report Forms

DEQ has created the following forms for electronic submission of data. Before requiring submission using these forms, DEQ will notify permit holders.

Please Note: Check this web page or contact DEQ at 503-229-6400 for  more information about dates and deadlines for Individual Minor and General permits. When a deadline is set, DEQ will immediately notify the appropriate permit holders.

Use DEQ’s WQ Permits Database to look up a permit and determine if it is classified as an NPDES Major, Minor or General Permit.

Benefits of electronic reporting

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.
