A recent approval of a Milwaukee River Basin TMDL (Total Maximum Daily Load) requires increased reduction of non-point source pollution by all area Municipal Separate Storm Sewer System (MS4) permit holders. More than two hundred municipalities in Wisconsin that include cities, villages, towns and counties within urbanized areas are required to have MS4 permits under NR 216, Wis. Adm. Code
The Village of Shorewood's discharge of stormwater is governed under a permit that is issued jointly to the seven North Shore communities (City of Glendale and Villages of Bayside, Brown Deer, Fox Point, River Hills, Shorewood and Whitefish Bay).The most recently issued version of the permit (2013-2018), Wisconsin Pollutant Discharge Elimination Systems Permit Number WI-S061565-2 (PDF) can be viewed here. The Wisconsin Department of Natural Resources (WDNR) is in the process of revising and reissuing this permit to incorporate the new TMDL guidance.
The Village of Shorewood was awarded a grant from the WDNR to address TMDL requirements and provide updates to the Village's 1997 Stormwater Management Plan.
