## Abstract

On December 10, 2009, Indiana submitted a request for a revision to its sulfur dioxide (SO<INF>2</INF>) state implementation plan (SIP) for the ArcelorMittal Burns Harbor LLC (ArcelorMittal) facility in Porter County, Indiana. This revision would remove the SO<INF>2</INF> emission limit for the blast furnace gas flare at the facility. The Environmental Protection Agency (EPA) proposed to disapprove this requested revision on March 20, 2013. The EPA is addressing comments and finalizing the disapproval action.
