Abstract
The Environmental Protection Agency (EPA) is approving a revision to the Illinois State Implementation Plan (SIP) submitted on January 23, 2020, by the Illinois Environmental Protection Agency (IEPA). The revision removes the variance from the sulfur dioxide (SO<INF>2</INF>) requirements of the Illinois Administrative Code (IAC) Multi-Pollutant Standard Rule for coal-fired electrical generating units (EGUs) owned by the Illinois Power Holdings, LLC (IPH) and the AmerenEnergy Medina Valley Cogen, LLC (Medina Valley), and will reimpose tighter limits on all facilities currently in operation.
