eReporting Overview

EPA requires the following 2021 MSGP forms be submitted electronically unless granted a waiver from the EPA Regional Office:

  • Notice of Intent (NOI)
  • Change NOI
  • Annual Report
  • Notice of Termination (NOT)
  • Discharge Monitoring Report (DMR) and
  • Conditional No Exposure Certification (NOE)

New NOIs, Change NOIs, Annual Reports, NOTs, and NECs

NeT-MSGP is accessed through EPA’s Central Data Exchange (CDX). Access the NeT-MSGP directly, or follow the instructions below:

Accessing NetDMR

EPA requires operators to use NetDMR to electronically prepare and submit all Monitoring Reports (DMRs) under the 2021 MSGP.

NetDMR is separate from NeT-MSGP and requires separate registration.

Register for NetDMR

  1. Access the NetDMR homepage.
  2. Select your EPA regional regulatory authority and click on the link to register for a new account.

    Note: If you are registering for a Signatory role—so you can electronically sign and submit DMRs—you first must sign and submit a Subscriber Agreement (SA) to the EPA regional regulatory authority. This can be done electronically or via paper.

Reporting Changes in Monitoring Requirements

NetDMR automatically populates your electronic DMR form with monitoring parameters and frequency from information submitted on your NOI form (i.e., industrial sector(s), discharges to impaired waters, applicable numeric effluent limits). It also will update your form as you report changes to your monitoring requirements.

EPA requires you to report the following changes to your monitoring schedule by submitting a Change NOI form in NeT-MSGP:

  • Benchmark and/or impaired monitoring requirements now apply because your facility has changed from inactive and unstaffed to active and staffed or circumstances change, and industrial materials or activities become exposed to stormwater.
  • If after submitting your NOI, you need to correct or update any fields (i.e., your activities change triggering monitoring for any discharge point, the water body into which you are discharging is considered impaired, etc.).

You no longer are required to report monitoring results using NetDMR once you have fulfilled your monitoring requirements for the permit term.

You are required to continue reporting your results using NetDMR if you have only partially fulfilled your benchmark and/or impaired waters monitoring requirements; for example:

  • Your four-quarter average is below the benchmark for some but not all parameters, or
  • You detected some—but not all—impairment pollutants.

For other benchmark monitoring schedule changes, or if there are any errors with the parameters and monitoring frequency on your DMR form, contact NPDESeReporting@epa.gov or call 866-352-7755 between 8 a.m.–5 p.m. ET to request changes to your DMR form.
