MS4 (Municipal Separate Storm Sewer System) permittees who have a U.S.EPA-approved total maximum daily load wasteload allocation (WLA) that they are not meeting must annually report on progress made toward achieving those WLAs. This is achieved by submitting an annual report on a Minnesota Pollution Control Agency (MPCA) form approved by the MPCA Commissioner. This page provides links to guidance on completing that form, including links to resources and tools used to complete the form.

NOTE: Permit requirements differ for Phase 2 MS4s and the two Phase 1 cities (St. Paul and Minneapolis), so the page is divided into separate sections based on those differing requirements.

Phase 2 MS4s

Warning: Due to the design of a new E-service Annual Reporting system, Phase 2 MS4s will not have an annual report due for the 2020 MS4 General Permit in calendar year 2023. See Guidance for completing the TMDL reporting form for further information
