MS4 Notice of Intent (NOI) Program Compliance
The Illinois Environmental Protection Agency (Illinois EPA) updated their Notice of Intent (NOI) requirements in 2020. The NOI outlines action’s the permittee will conduct for the next five years to be compliant with the MS4 permit program. Please note that as of February 28, 2021, the Illinois EPA has NOT issued a new version of its General NPDES Permit No. ILR40 (Permit). The permit effective on March 1, 2016, and that expired on February 28, 2021, is being administratively continued by the Illinois EPA.
The NOI 2020 version is a document that the Illinois EPA requested that each Municipal Separate Storm Sewer System (MS4) permittee submit by February 28, 2021. Individual MS4 permittees should contact the Illinois EPA regarding any submittals after 2/28/2021 to confirm compliance acceptance. The only written guidance available to the ILR40 NOI submittal date permit language: Page 16 of the ILR40 permit (2016-2021), Attachment H (2) Duty to Reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee must apply for and obtain a new permit. If the permittee submits a proper application as required by the Agency no later than 180 days prior to the expiration date, this permit shall continue in full force and effect until the final Agency decision on the application has been made.
Lake County SMC has provided QLP template documents to aid MS4 communities with the new NOI requirements. (https://www.lakecountyil.gov/3850/Notice-of-Intent-NOI).
