## Abstract

EPA is approving sulfur dioxide, particulate matter (PM), and nitrogen oxides emission limitations and related requirements for the Southern Indiana Gas and Electric Company's F.B. Culley Generating Station (Culley Station). Indiana requested a revision to its State Implementation Plan (SIP) on September 11, 2008. Most of the provisions to be added are contained in a Federal consent decree. In addition, Indiana has removed expired sulfur dioxide emission limits from its regulations. These requirements are consistent with section 110 of the Clean Air Act as revisions to the Indiana State Implementation Plan (SIP).
