The Environmental Protection Agency (EPA) is approving a revision to the Illinois State Implementation Plan (SIP) to amend requirements applicable to certain coal-fired electric generating units (EGUs) in the Illinois Administrative Code, also known as the Multi- Pollutant Standards (MPS) Rule. On January 23, 2020, the Illinois Environmental Protection Agency (IEPA) submitted a request to amend the provisions of the MPS Rule in the Illinois regional haze SIP. EPA is approving the revision because it will result in a significant decrease in emissions of Oxides of Nitrogen and Sulfur Dioxide, meets the applicable requirements of the Clean Air Act (CAA), and does not interfere with any applicable requirement concerning attainment and reasonable further progress.
