Summary

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Indiana sulfur dioxide (SO<INF>2</INF>) State Implementation Plan (SIP) for the steel mill in Burns Harbor, Porter County, Indiana, formerly owned by ArcelorMittal Burns Harbor LLC and currently owned by Cleveland-Cliffs Burns Harbor LLC (the Burns Harbor plant). Final approval of these revisions would satisfy a provision in a Federal Settlement Agreement. EPA approval would also strengthen the Indiana SO<INF>2</INF> SIP by lowering SO<INF>2</INF> emission limits and adding SO<INF>2</INF> compliance test procedures for the Burns Harbor plant. EPA is proposing to approve this SIP revision request.
