Transition to NetDMR for Electronic WYPDES Discharge Monitoring Report Submittals

This spring, the Wyoming Department of Environmental Quality (DEQ), Water Quality Division will begin transitioning to NetDMR for electronic submission of WYPDES discharge monitoring reports (DMRs). NetDMR is a web-based tool provided by EPA that allows permittees to electronically sign and submit DMRs to meet permit requirements. Previously, the Water Quality Division has facilitated electronic DMR submission through its eDMR system. As a newer system, NetDMR will offer streamlined sign-up and reporting processes to simplify DMR submittals for permittees and enhance benefits that include, but are not limited to, improved data availability, improved communication through email notifications, and improved data quality assurance/quality control. This transition is part of the Water Quality Division’s ongoing efforts improve efficiency and public transparency through the use of digital processes. In addition, the transition is an important component of ensuring compliance with the National Pollutant Discharge Elimination Electronic Reporting Rule.

In April, WYPDES staff will start contacting select permittees to begin the transition. Note that permittees will be transitioned to NetDMR in phases, and most permittees will not be contacted until the summer or fall to begin the transition. The DEQ anticipates a complete transition by the end of 2021. Outreach and training on NetDMR will be provided.

NPDES Electronic Reporting Rule (E-Rule)

On December 21, 2015, the U.S. Environmental Protection Agency (EPA) first enacted the
NPDES Electronic Reporting Rule (E-Rule) to modernize Clean Water Act reporting. The rule
pushed for municipalities, industries, and other facilities covered by the NPDES permitting
program to switch over to electronic data reporting instead of submitting paper Discharge
Monitoring Reports (DMR). The rule required that all NPDES permittees submit their DMRs
through some electronic reporting system.

NetDMR and the benefits of electronic reporting

NetDMR is a web-based reporting system developed by the EPA and channeled through the
Central Data Exchange (CDX) system. Reporting on NetDMR requires only a computer, an
Internet browser, and high-speed access to the Internet.

Electronic reporting through NetDMR has several benefits including but not limited to: saving
time and resources for permittees while increasing data accuracy, reducing submission errors,
and improving compliance. Electronic reporting in general can help facilities and the state
streamline data and provide better clarity and compliance transparency by providing a faster,
more complete, more accurate, and nationally-consistent set of data.
EPA also provides direct assistance and several training materials and sessions on how to sign up
and use NetDMR, which is discussed below.

How to register and use NetDMR

As previously mentioned, NetDMR is facilitated through EPA’s CDX system, so in order to get started, a person must first create a CDX account. (Note: If you already have an existing CDX account, you may be able to skip this process). Once that has been approved, a person can
register for a signatory or other reporting role for their permit through the NetDMR system.
There are types of CDX and NetDMR accounts. One is for the test system and one is for the production system. Signing up for the test system can be beneficial as it will allow new users to become familiar with NetDMR before starting to submit DMR data through the production system. Ultimately, everyone needs to sign up for the production system.

The link for CDX Test is: https://test.epacdx.net/.
The link for CDX Production is: https://cdx.epa.gov/.

NetDMR Test can be accessed through the following link: NetDMR Test.
NetDMR Production can be accessed through the following link: NetDMR Production.

Training Materials and Guidance Documents

EPA has provided a NetDMR support page, which provides user guides, fact sheets, videos, and
other training materials on how to sign up and use NetDMR. In addition, they provide quarterly
webinar trainings to provide NetDMR users with basic understandings on how to access,
navigate, and use the NetDMR tool for the purpose of electronically reporting DMR data. The
support portal also provides direct support through the submission of a support request ticket or
by calling the contact line directly.

The NetDMR Support Portal and the materials and links to webinars, etc. can be found below:

The sign up process for CDX is the same for both the test site and the production site. EPA CDX Online Registration User Guide. A Power Point presentation on how to create a CDX can also be downloaded below.

An EPA user guide on how to create a NetDMR account and how to use NetDMR can be found here and downloaded below (PDF).

More state provided trainings and training material will also be created as the Wyoming DEQ
continues to move forward with this transition.
