Informational webinar, Tuesday April 14, 2015, 1:30 p.m. – 3:30 p.m.
In October 2014, the Department of Natural Resources issued guidance on the implementation of Total Maximum Daily Loads (TMDLs) through MS4 permits. The guidance provides direction to MS4 permittees and their consultants on how TMDL waste load allocations will be implemented within MS4 permits. The guidance also discusses how an MS4 permittee will be expected to model its MS4 service area and storm water management measures to show compliance with TMDL requirements.
This informational webinar will provide an overview of the guidance by DNR staff with an opportunity for participants to ask questions. There is no cost to participate and the webinar is open to everyone who is interested.
More than two hundred municipalities in Wisconsin that include cities, villages, towns and counties within urbanized areas are required to have Municipal Separate Storm Sewer System (MS4) permits under NR 216, Wis.
