On August 23, 1994, the United States Environmental Protection Agency (USEPA) granted conditional approval of revisions to the emission limitations, compliance methodologies, and compliance time schedules in Ohio's State Implementation Plan (SIP) for sulfur dioxide (SO<INF>2) as it applies to Hamilton County. The outstanding condition has been addressed, and USEPA is now fully approving the Hamilton County, Ohio, SO<INF>2 SIP. Submitted by Ohio in response to modeling analyses which predicted violations of the SO<INF>2 National Ambient Air Quality Standards (NAAQS) due to Hamilton County sources, this SIP has been demonstrated to provide for attainment and maintenance of the SO<INF>2 NAAQS in Hamilton County.
