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).

NBWW Members NOI Spreadsheet
MS4 communities in the workgroup can recognize the NBWW’s in-stream monitoring data (including sediment sampling) for their NPDES permit compliance as a component of Collaborative watershed-scale monitoring. Ashley Strelcheck, NBWW Coordinator, has provided an NOI spreadsheet detailing NBWW’s monitoring strategy. This spreadsheet can be used as an MS4 program reference and can be included as an NOI reference in the WATER QUALITY AND SEDIMENT MONITORING PROGRAMS Section of the NOI. MS4s should reference program participation, include the spreadsheet hyperlink. For more information on how to utilize this NOI spreadsheet please contact Ashley Strelcheck, astrelcheck@lakecountyil.gov.

NBWW Annual Workplan Scorecards
See the NBWW Annual Workplan Scorecards (under Plans & Reports webpage) strategy tables are specific program activities that can be included as measurable goals to meet the minimum control measures (MCM) of the NPDES ILR40 permit requirements. “Corresponding MS4 MCM” column should be reflected as measurable goals in the Stormwater Management Program Plan (SMPP) as well as annual facility inspection report. “Water Quality (WQ) Requirement” supports Part 5 of the NPDES ILR40 Permit.
