Abstract
The Environmental Protection Agency (EPA) is approving a revision to the Illinois State implementation plan (SIP). The revision, submitted on May 30, 2019, incorporates several revisions to the Illinois air pollution control rules entitled "Part 243--Ambient Air Quality Standards" related to the National Ambient Air Quality Standards (NAAQS). The revision updates the "List of Designated Reference and Equivalent Methods" in response to EPA rulemakings. In addition, Illinois addresses EPA's revocation of the 1971 sulfur dioxide and the 1978 lead NAAQS.
