NetDMR and Electronic Reporting

The NPDES Electronic Reporting Rule was published in the Federal Register on October 22, 2015, and will be implemented in two phases, Phase I and Phase II. Phase I became effective on December 21, 2016 and replaces paper-based Discharge Monitoring Reports (DMRs) and Biosolids Annual Program Reports with electronic reporting. Network Discharge Monitoring Report (NetDMR) is an electronic reporting tool  that allows NPDES-regulated facilities to submit DMRs electronically to EPA through a secure Internet application.

All NPDES permittees with DMR requirements are required to submit DMRs electronically, and as of May 2017, over 90% of all Tennessee NPDES permittees are reporting in NetDMR.

For NPDES permittees who are unable to meet the electronic reporting requirements, the rule provides flexibility for states to grant temporary or episodic waivers from electronic reporting. To obtain an electronic reporting waiver, permittees must first submit an electronic reporting waiver request by email to or by mail to:

    Division of Water Resources
    NetDMR Waivers
    Tennessee Tower, Eleventh Floor
    312 Rosa L. Parks Ave.
    Nashville, TN 37243
