of 2014, the City of Oshkosh received notification this coverage was extended to include the newly-

compliance with the MS4 Permit requirements. All information is entered on the WDNR website
through the online forms. In addition to the information requested in the online forms, a document
containing supplemental information that the forms did not have room to enter was prepared and
uploaded as an attachment. City staff has more details available for the WDNR, should they request
