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 in 2017 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. These reports will be submitted using EPA’s NeT tool, available through NPDES permittees’ CDX accounts. 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

If an NPDES permit holder’s permit is set up in the NetDMR system, they can begin testing now. Please check with DEQ’s NetDMR support staff to determine if your permit has been set up in the system. Some permit holders will receive packets of information from DEQ. These packets will contain specific information about the permit. DEQ staff will help permit holders navigate permit and DMR setup in the NetDMR system.

You can also contact DEQ using our NetDMR Support Line at 503-229-6400.

Already contacted support? Take our online survey to help us serve you better.

After the testing, permit holders will be expected to register in groups by permit classification, and complete registration along with their first electronic submission by the target date specified below:

  • Individual “Minor” NPDES Permits: Aug. 15, 2018 for NetDMR Test, date for NetDMR Production TBD
  • General NPDES permits:  TBD


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.
