Adequacy Status of the Steubenville, OH and the Canton, OH Submitted Annual Fine Particulate Matter Attainment Demonstration for Transportation Conformity Purposes

Краткое содержание

In this notice, EPA is notifying the public that we have found that the motor vehicle emissions budgets (MVEBs) for fine particulate matter (PM 2.5 ) and oxides of nitrogen (NO x ) as a precursor to fine particulate matter in Steubenville, Ohio (Jefferson County) and Canton, Ohio (Stark County) are adequate for use in transportation conformity determinations. Ohio submitted the Steubenville and Canton area budgets with the attainment demonstration submittal initially on July 16, 2008, and subsequently submitted the public hearing results on December 5, 2008. As a result of our finding, the Steubenville, Ohio area (Jefferson County) and the Canton, Ohio area (Stark County) must use the MVEBs from the submitted PM 2.5 attainment demonstration plan for future transportation conformity determinations.
