RIPDES Electronic Reporting

Rev. 12/5/23


EPA signed the National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule  on September 24, 2015 and it was published in the Federal Register on October 22, 2015. The rule replaces most paper-based NPDES reporting requirements with electronic reporting and will modernize Clean Water Act (CWA) reporting for municipalities, industries and other facilities.

Specifically, the rule requires regulated entities to report information electronically, instead of filing written paper reports. These reports include:

  • Discharge Monitoring Reports (DMRs)
  • Notices of Intent to discharge in compliance with a general permit
  • Other specified program reports

Data reported electronically will be made available to the public via the Enforcement and Compliance History Online (ECHO) system. ECHO enables public searches for facilities in local communities to assess their compliance with environmental regulations. It can also help investigate pollution sources, examine and create enforcement-related maps, or explore states' performance.

All electronic submissions require a Central Data Exchange (CDX) account. DMRs are submitted through the NetDMR-RI program service, which is hosted on the CDX Website.
