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>. On July 8, 2004, at 69 FR 41344, EPA proposed to approve the requested revisions and to redesignate Cuyahoga County as requested. EPA also published a corresponding direct final rule on the same date, at 69 FR 41336, but EPA withdrew this direct final rule because it received an adverse comment. A citizen from New Jersey expressed concern about air pollution coming east from Ohio and urged EPA to require Ohio power plants to upgrade their pollution controls. EPA is satisfied that the SO<INF>2</INF> emission limits submitted by Ohio suffice to assure attainment of the SO<INF>2</INF> air quality standard. EPA notes further that a separate action proposed on January 30, 2004, at 69 FR 4566, known as the Clean Air Interstate Rule, would require significant reduction in the emissions of SO<INF>2</INF> and nitrogen oxides (NO<INF>X</INF>) of power plants in Ohio and elsewhere for purposes of reducing their long-range transported contributions to fine particulate matter and ozone exposures. EPA also received a comment from an affected company clarifying the operational status of boilers affected by the relevant rule. EPA affirms this clarification. Thus, as proposed, EPA is approving the SO<INF>2</INF> rules Ohio submitted, removing the Federal Implementation Plan rules that these State rules supersede, and redesignating Cuyahoga County to attainment for SO<INF>2</INF>.
