Approval and Promulgation of Air Quality Implementation Plans; Ohio; Redesignation of the Canton-Massillon Area to Attainment of the 1997 Annual Standard and the 2006 24-Hour Standard for Fine Particulate Matter

EPA is approving, under the Clean Air Act (CAA), the state of Ohio's request to redesignate the Canton-Massillon nonattainment area (Canton), Stark County, to attainment of the 1997 annual and 2006 24- hour national ambient air quality standards (NAAQS or standards) for fine particulate matter (PM<INF>2.5</INF>). On June 26, 2012, the Ohio Environmental Protection Agency (OEPA) submitted a request for EPA to redesignate the Canton nonattainment area. EPA determined that the Canton area has attained the 1997 annual and 2006 24-hour PM<INF>2.5</INF> standards, and proposed on August 7, 2013, to approve Ohio's request to redesignate the area. EPA is taking final action today on that proposal. EPA is also taking final action in this rulemaking on several related proposals. EPA is approving, as a revision to the Ohio state implementation plan (SIP), the state's plan for maintaining the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS in the area through 2025. Finally, EPA finds adequate and is approving Ohio's nitrogen oxides (NO<INF>X</INF>) and PM<INF>2.5</INF> motor vehicle emission budgets (MVEBs) for 2015 and 2025 for the Canton area. EPA is also approving the 2005 and 2008 emissions inventories for primary PM<INF>2.5</INF>, NO<INF>X</INF>, sulfur dioxide (SO<INF>2</INF>), volatile organic compounds (VOCs) and ammonia for the area. EPA, therefore, grants Ohio's request to redesignate the Canton area to attainment for the 1997 annual and 2006 24-hour PM<INF>2.5</INF> standards.
