EPA’s Electronic Reporting Rule
, modernizes reporting for municipalities, industries and other facilities that hold National Pollutant Discharge Elimination System (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 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 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:
|Individual major NPDES permits
||Permittees are reporting electronically already|
|General NPDES permits (including stormwater permits)
||Permittees will transition to electronic reporting according to the rollout schedule for Your DEQ Online |
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.
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.
Online training is available any time
There are no in-person trainings scheduled at this time. We will update this page when future in-person training events are scheduled.

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.
