Forms, guidance, and resources for completing the TMDL annual report form

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.
