Information: alert-danger
Warning: The MPCA is in the process of developing a new e-service for both the Phase II MS4 annual report and the TMDL annual report. There will be no TMDL Annual Report submission in calendar year 2023 for Phase II MS4 permittees.
Contents
Purpose of the TMDL Annual Report
If you (an MS4 Permittee) are assigned one or more Wasteload Allocation (WLA) in a Total Maximum Daily Load (TMDL) that was approved by the United States Environmental Protection Agency (USEPA) prior to November 16, 2020, and were not meeting the WLA(s) when you applied for permit coverage, you must complete the TMDL Annual Report to demonstrate progress toward meeting the WLA(s).
E-service TMDL Annual Reporting for Phase II MS4 permittees
The MPCA is in the process of developing a new e-service for both the MS4 annual report and the TMDL annual report. There will be no TMDL Annual Report submission in calendar year 2023. Permittees will be expected to report on 2022 activities once the e-service is operational.
Until the e-service is operational, permittees should keep track of the following:
For Total Phosphorus, Total Suspended Solids, and Oxygen Demand WLAs not being met or requiring further analysis at time of the 2020 MS4 general permit application submittal
- Updates on BMPs included in the compliance schedule submitted by the permittee as part of the application for the 2020 MS4 general permit
- Implemented BMPs for each applicable WLA since the Total Maximum Daily Load (TMDL) baseline year, including:
- BMP category, BMP type, and BMP status (see TMDL annual report webpage for more information)
- For constructed basins, filtration, infiltration, stormwater reuse, and street sweeping BMPs:
- Location (i.e., geographic coordinates)
- Quantitative pollutant reductions per BMP
For chloride TMDLs
- Amount of deicing salt used each winter maintenance season
- Certify completion of an annual winter maintenance assessment
- Guidance for meeting chloride TMDL MS4 permit requirements
For temperature TMDL
- Status of temperature management plan
- Guidance for meeting temperature TMDL MS4 permit requirements
For bacteria TMDLs
- Status of inventory and prioritization plan
- Guidance for meeting bacteria TMDL MS4 permit requirements
