Discharge Monitoring Reports (DMR)

New eDMRs

What is a DMR?

Discharge Monitoring Report (DMR) forms are provided by the Minnesota Pollution Control Agency (MPCA) for reporting monitoring results required by the National Pollutant Discharge Elimination System (NPDES)/State Disposal System (SDS) permit for a wastewater treatment system. These forms are generated directly from the limits and monitoring requirements in the permit. They are generated after the original issuance of a  new permit, final reissuance of an existing permit, or modification of a permit which changes the monitoring requirements and/or permittee/facility name or address. They are generated by the Pollution Control Data Specialist (PCDS) assigned to manage the data for your facility and will be available online within 45 days of a permit action.

How to complete your DMR

To fill out the DMRs properly be sure to have all necessary recordings (i.e. flows, precipitation) and analytical results. All of this data should be recorded on the Supplemental Report Form (if required) or the forms you use to record your daily operations data. Calculations will be required so it’s a good idea to have the Permit Calculations and Definitions document handy. The gray boxes will have the value type and numeric limit if one applies. Quantity and concentration units are to the right of their respective columns for each parameter. Values should always be reported in these units. Values must be recorded above each of these boxes in the blank white boxes when there is activity at the monitoring station. If a box contains asterisks, no value is required.

The last two columns at the far right of each form are to confirm that sampling is being completed at the same frequency and sample type as required by your NPDES Permit. If it is the same as indicated in the gray portions in each of these two columns, leave as is. If the frequency or sample type is different, the actual frequency or sample type must be indicated in the blank box.

  • If there is No Flow or No Discharge, the field should say, "Yes."
  • If there is flow or a discharge, the field says, "No," and data is reported.
  • The electronic version of the DMR only accepts numeric values and the <., >, or decimal symbols.

Supplemental Report Forms

Supplemental Report Forms may also be required for detailed monitoring results. You may use your own supplemental forms for reporting more detailed data without MPCA approval provided all required identifying information is present on the form. The Supplemental Report Forms must have all recordings and analytical results recorded on the date they were taken.

eDMRs — New

All permittees must be signed up and submitting eDMRs by December 31, 2012. We highly recommend signing up as soon as possible. Permittees must sign up prior to their first submittal. The sign up process involves submitting a document signed by the permit owner that designates who is responsible for electronic submittal. The wastewater operator does not have to be the online subscriber and is not required to complete the DMRs electronically, however that person is responsible for the operation of the wastewater facility, including sampling, process operation, and DMR calculations. The Permittee may authorize and have multiple online subscribers.

We recommend signing up for eDMRs at least 2-3 weeks before you are required to submit a DMR. After you sign up for eDMRs and at least one week prior to submitting your first eDMR, you should verify that the system allows the eDMR submittal. You can do this by logging on to the system, accessing an available eDMR and submitting the form.

eDMRs of the future — new and improved — coming in 2013

MPCA staff continue work on a process for Permittees to submit individual monitoring results (unsummarized) data in an electronic file format. This differs from the current process in which the monitoring results are submitted as an attachment to the eDMR. Permittees will either enter data into a monitoring result form — on-line (similar to a supplemental form) or complete an Excel spreadsheet to upload. An optional calculator will be available to most facilities.

If you chose to use the calculator, there will be a way to populate the eDMR form using the calculated values. You will be required to review and confirm the eDMR calculated values prior to submittal.  As with the current eDMR process, you will receive an email that verifies submittal completion.

We appreciate your interest in this process. We welcome your comments, concerns, and questions on the upgraded system. We intend to meet with Permittees in a variety of ways — regional meetings, webinars, teleconferences, etc. — and will continue to provide information in a variety of ways — email, letter, etc. We will use this web page to post information that might be of interest to you and meeting/webinar/teleconference schedules.

We understand daily values and electronic submittal will be new to many Permittees.  We hope to make the process as seamless as possible.  We hope you see the benefits of the daily values project:

  • No more worries about the mail!
  • The system calculates the DMR summary data.
  • You can access your submitted daily values and DMRs at any time in the future.
  • You can amend them, too!

When are Discharge Monitoring Reports due?

Accurate, timely reporting is essential in complying with the NPDES permit. DMRs are due/postmarked and/or electronically submitted by the 21st of the month following the monitoring period (e.g. January's DMR is due February 21st).

Send the original DMR with the Supplemental Report Form (if applicable) to:

Minnesota Pollution Control Agency
Attention: Discharge Monitoring Report
520 Lafayette Road North
St. Paul, MN  55155-4194

All other permit-required submittals should be sent to:
