Abstract
The Environmental Protection Agency (EPA) is approving revisions to the Indiana sulfur dioxide (SO<INF>2</INF>) State Implementation Plan (SIP). The State of Indiana has requested these SIP revisions to satisfy the requirements of a Federal consent decree. These revisions limit annual bypass venting limits in the sulfur- containing waste gas emissions from a coking and power generating facility in Lake County, Indiana, which is owned and operated by Indiana Harbor Coke Company (IHCC) and Cokenergy LLC (Cokenergy). The revisions also require Cokenergy to operate and maintain a permanent SO<INF>2</INF> flow rate monitor and improve the percent control capture efficiency of the facility. In addition, the rulemaking includes technical corrections and clarifications that do not have a substantive effect of the application of the rules.
