The Network Discharge Monitoring Report (NetDMR) tool is freely available for use by EPA Regions and select States, Tribes, and Territories. Most EPA Regions and many states are currently utilizing NetDMR. Additional States, Tribes, and Territories may adopt NetDMR and quickly enable their regulated NPDES facilities to begin electronic reporting.

NetDMR is a national tool for regulated Clean Water Act permittees to submit discharge monitoring reports (DMRs) electronically via a secure Internet application to U.S. EPA through the Environmental Information Exchange Network. NetDMR allows participants to discontinue mailing in hard copy forms under 40 CFR 122.41 and 403.12.

Please visit this site often for deployment updates, schedules, and other information for the NetDMR Community.

News / Announcements:

  • 10/28/2015 - Frequency of Analysis Code 02/02 Removed!!
    It was brought to our attention that the Frequency of Analysis "Twice per Week" had two codes (02/02 and 02/07).
    To correct this, the code 02/02 was deleted and all limits and DMR data that used that code were updated to 02/07.
    We apologize for all and any inconveniences this change has caused.
