Résumé
In this notice, EPA is notifying the public that we have made insignificance findings through the transportation conformity adequacy process for directly emitted fine particulate matter (PM 2.5 ) and oxides of nitrogen (NO X ) in Washington County, Ohio (part of the Parkersburg/Marietta annual PM 2.5 nonattainment area) and the Ohio portion of the Huntington/Ashland annual PM 2.5 nonattainment area. Ohio submitted the attainment demonstration State Implementation Plan (SIP) for annual PM 2.5 initially on July 16, 2008, and subsequently submitted the public hearing results on December 5, 2008. As a result of our finding, Washington County, Ohio and the Ohio portion of the Huntington/Ashland area are no longer required to perform a regional emissions analysis for either directly emitted PM 2.5 or NO X as part of future PM 2.5 conformity determinations for the 1997 annual PM 2.5 air quality standard.
