Air Plan Approval; Illinois; Public Participation in the Permit Program

The Environmental Protection Agency (EPA) is approving revisions to the Illinois State Implementation Plan (SIP) that were submitted on August 27, 2020 by the Illinois Environmental Protection Agency (IEPA). These revisions affect the public notice rule provisions for the New Source Review (NSR) and title V Operating Permit programs (title V) of the Clean Air Act (CAA). The revisions remove the mandatory requirement to provide public notice of draft CAA permits in a newspaper and allow electronic notice (e-notice) as an alternate noticing option. EPA proposed to approve this action on February 26, 2021 and received no adverse comments.
