  • Amend previously submitted DMRs

National Pollutant Discharge Elimination System (NPDES)/State Disposal System (SDS) permits for wastewater treatment require the reporting of discharge monitoring results. Visit the DMR e-services page to submit your data. The online form will display the limits and monitoring requirements from your permit. The forms are updated within 30 days of a permit action, such as issuing a new permit or modifying or reissuing an existing one.

Before submitting reports through the online system, all permittees must:

  • Create an MPCA e-services account
  • Submit an authorization agreement signed by the responsible official that names the account holder (the person in charge of electronic submittal). The account holder must also sign the agreement (see Account management section below).

The MPCA will email the account holder when it has approved the authorization. The account holder does not have to be the wastewater operator responsible for sampling, process operation, and DMR calculations, and permittees may authorize multiple account holders. Sign up at least two to three weeks before your DMR is due. A week before submitting your first DMR, log onto the system to verify the system allows submittal.

Sample values

Daily sampling and monitoring data must be submitted on a sample values or operational spreadsheet, which are customized to your facility and available in e-services. At the end of the monitoring period, a feature in e-services can be used to calculate the required limit types for parameters on the DMRs. (Some facilities with special calculation instructions will have to calculate values based on specific permit requirements.) REMEMBER: You must review and confirm the calculated values prior to submittal. You'll receive an email verifying submittal of the DMR.

Quick tips: Filling out sample values and DMRs

No discharge/no flow
  • If you have a discharge, leave the "No Discharge/No Flow" box blank and report values in the parameter fields.
  • If you have no discharge or flow, mark the field with an "X" and leave the parameter fields blank.
Cancel in-progress sample values; or DMR or sample values spreadsheet are listed "in progress" To start over, click "My Workspace Tab" under "My Services in Progress," and click the red X. Make sure you are cancelling the DMR and not your facility!
DMR submitted prior to sample values, and sample values no longer an option for the monitoring period The sample values spreadsheet must be included as an attachment to the DMR.
No chlorine used; no results for a parameter Leave the boxes blank on the sample values and DMR forms and add a note to the DMR indicating that you did not chlorinate or that monitoring wasn't done. Do not put "0" or "NA" in the parameter boxes.
Reporting releases In months when there was a release, complete the release sampling report and attach it to the DMR. Find a blank form below in both Excel and Word formats.
Auto-calculation/rounding
  • Double check DMR boxes that are supposed to be automatically calculated, and fill in any missing values.
  • Check that figures are rounded correctly.
  • No more than 10 characters (including numbers, decimals, and < > symbols) in a box.
  • Report groundwater elevations to the nearest hundredths of a foot.

DMR guidance

When are DMRs due?

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

All other water quality submittals go to:

Minnesota Pollution Control Agency

Access DMR data

Example of search results from wastewater data browser

Submitted wastewater DMR data is available for selected areas, times, or parameters via the Wastewater Data Browser, which is refreshed quarterly. The data is for reference only. Work with your compliance staff if you have DMR reporting questions. Download the data displayed on screen from the lower right corner. You can still submit an information request if the information you are looking for isn’t available. Email datadesk.mpca@state.mn.us with any questions about the Wastewater Data Browser.
