NPDES Phase II

The Clean Water Act Amendments of 1987 established the NPDES stormwater program.  Phase I of the NPDES Stormwater program began in 1990 and required medium and large municipal separate storm sewer systems (MS4s) to obtain NPDES coverage.                                   


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:

As the new permit takes effect, SMC remains committed to providing a variety of stormwater management activities across the county and to assisting Lake County's MS4s in meeting the requirements of IL EPA's NPDES Municipal Stormwater Program.  Please contact 847-377-7700 if you should have any questions about IL EPA's new permit or municipal stormwater program.

In addition to completing your Annual Report, you should also complete and sign IL EPA’s Annual Facility Inspection Report Form. The Form may be placed on top of your Annual Report, as a cover sheet, to create your reporting packet.

As a reminder, your reporting packet (i.e., Annual Facility Inspection Report Form & Annual Report) should be sent to IEPA by no later than June 1, 2016.  The packet should be submitted directly to IEPA using the following e-mail address: epa.ms4annualinsp@illinois.gov; there is no need to submit a copy to SMC.

Please call 847-377-7700 if you should have any questions about the template or any questions about IL EPA's new permit or municipal stormwater program. ​​​​​
 

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.
