NPDES Electronic Reporting
Starting on August 19, 2024, EPA’s Central Data Exchange (CDX) login process will transition to using Login.gov for all user verification. When you log in to your NetDMR account after August 19, you will be prompted to create a new Login.gov account or log in to your existing Login.gov account, which will be merged with your existing NetDMR and CDX login information. For more information on the CDX login transition to Login.gov, please refer to EPA's NetDMR Help Center's CDX login transition to Login.gov- Step-by-step guides, including the Step-by-step guide for CDX -> Login.gov (Existing CDX users NEW to Login.gov).
MyTDEC Forms
The Division of Water Resources is in the process of launching the new MyTDEC Forms online customer portal for the submission of permit applications and annual reports. The MyTDEC Forms portal was created to comply with EPA’s National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule (eRule), which requires electronic reporting and sharing of NPDES program data. This rule is modernizing Clean Water Act (CWA) reporting for municipalities, industries, and other facilities and will replace most paper-based NPDES reporting requirements with electronic reporting.
The Federal rule requires the State to share data electronically with EPA, thereby expediting the collection and processing of the data, thus making it more accurate and timelier. Additionally, data reported electronically such as facility-specific information, inspection and enforcement history, pollutant monitoring results, and other data required by NPDES permits will be made available to the public through EPA’s Enforcement and Compliance History Online website. It was designed to save program resources, make reporting easier, streamline permit renewals, ensure a full exchange of basic NPDES permit data between states and EPA, improve environmental decision-making, and better protect human health and the environment.
The division will publish 17 forms in multiple stages throughout 2021 to allow permittees and staff time to learn the new system.

- Notice of Intent (NOI) for General NPDES Permit for Stormwater Discharges from Construction Activities (TNR100000)

- Currently reporting on the eMOR form (Yes = Earlier Wave)
- Receives waste from a satellite collection system (Yes = Later Wave)
- Permit has overflow and release language (Yes = Earlier Wave)
- Permit overflow and release language has been appealed (Yes = Later Wave)
- Permittee communicates a preference to online reporting (Yes = Earlier Wave)

NetDMR Electronic Reporting
Phase I of the NPDES Electronic Reporting Rule became effective on December 21, 2016. The Rule replaces paper-based Discharge Monitoring Reports (DMRs) with electronic reporting and requires all NPDES permittees with DMR requirements to submit DMRs electronically through EPA’s secure Network Discharge Monitoring Report (NetDMR) website. As of July 2024, over 99% of all Tennessee NPDES permittees are reporting in NetDMR.
Resources for how to use NetDMR are available on EPA’s NetDMR Support Portal and on TDEC’s Reporting in NetDMR webpage.
For assistance with NetDMR account registration, NetDMR account management, or reporting, correcting, or deleting DMR data in NetDMR, permittees, and data providers can contact Tennessee’s Regulatory Administrator, Bri Begley, by phone at 423-268-4770 or by email at Brianne.Begley@tn.gov.
