Important information concerning the DNR’s MS4 General Permits
The DNR is in the process of issuing WPDES MS4 general permits WI-S050075-2 and WI-S050181-1. The public notice, proposed general permits and fact sheets are available. The municipalities potentially affected by each general permit are listed in the fact sheet available in the column labeled “Supporting Documents”.
The DNR will hold a public informational webinar for each proposed general permit.
