On September 27, 2003, Ohio requested revisions to the State Implementation Plan (SIP) for sulfur dioxide (SO<INF>2</INF>) for several counties in Ohio, along with a request for redesignation of Cuyahoga County to attainment for SO<INF>2</INF>. In general, the submitted rules are at least equivalent to limitations promulgated by EPA in a Federal Implementation Plan (FIP) for the area. Therefore, EPA is approving these revisions to the SIP. In conjunction with this action, EPA is rescinding the federally promulgated emission limitations for SO<INF>2</INF> for these counties. By this pair of actions, EPA is replacing FIP limits with SIP limits for the affected counties. EPA finds Ohio's request for the redesignation of Cuyahoga County to attainment for SO<INF>2</INF> approvable. EPA believes that the prerequisites for redesignation to attainment are satisfied, including meeting the air quality standard, replacing FIP limits with federally approved state limits, providing an approvable plan for continued attainment, and addressing other relevant planning requirements. Therefore, EPA is redesignating Cuyahoga County to attainment for SO<INF>2</INF>.
