Illinois EPA's New MS4
Illinois EPA (IL EPA) has issued a new version of its NPDES Permit No. ILR40 (MS4 Permit). The new permit became effective on March 1, 2016.
IL EPA’s new permit contains a variety of new and modified requirements that will impact local stormwater management programs. SMC has reviewed the new permit, compared it to the previous permit, summarized the changes, and evaluated what the changes appear to mean for Lake County MS4s. This information is available below:

Illinois EPA's Municipal Stormwater Program in Lake County
Municipal Advisory Committee
The countywide approach that has been taken toward the implementation of IL EPA’s NPDES Municipal Stormwater Program in Lake County places SMC in the role of a Qualifying Local Program (QLP). In this role, SMC proactively formed the MAC as a way to coordinate the efforts of Lake County MS4s during implementation of IL EPA’s NPDES Municipal Stormwater Program. SMC continues to facilitate MAC meetings and to provide general support to Lake County MS4s as they implement their stormwater management programs.
