EPA is notifying the public that it has made a finding that Ohio's July 11, 2002 submission regarding State Implementation Plan (SIP) revisions for the reduction of oxides of nitrogen (NO<INF>X</INF>) is a complete submission under the Clean Air Act. Ohio's SIP revision was submitted to satisfy EPA's October 27, 1998 regulation entitled, "Finding of Significant Contribution and Rulemaking for Certain States in the Ozone Transport Assessment Group Region for Purposes of Reducing Regional Transport of Ozone," otherwise known as the "NO<INF>X</INF> SIP Call". The NO<INF>X</INF> SIP Call originally required 22 states and the District of Columbia to submit enforceable SIP measures to control NO<INF>X</INF> emissions. The intended effect of a NO<INF>X</INF> SIP revision is to reduce emissions of NO<INF>X</INF> in order to help attain the national ambient air quality standard for ozone. On December 26, 2000, EPA determined that Ohio, along with several other states, had failed to submit a SIP in response to the NO<INF>X</INF> SIP Call, thus starting an 18-month clock for the mandatory imposition of sanctions and the obligation for EPA to promulgate a Federal Implementation Plan (FIP) within 24 months. On July 11, 2002, Ohio submitted a NO<INF>X</INF> SIP and EPA has determined that Ohio's SIP submission is complete. Therefore, through this rule, EPA is notifying the public that the sanctions clock as it pertains to Ohio is terminated. This determination is limited to the completeness of Ohio's submission and is not an approval of Ohio's plan. A determination as to the adequacy of Ohio's plan will be made at a later date and only after a thorough review of Ohio's submission by EPA personnel and the completion of rule and comment rulemaking.
