Adequacy Status of Motor Vehicle Emissions Budget in Submitted State Implementation Plan; Maricopa County PM-10 Nonattainment Area, Arizona

Résumé

In this notice, EPA is notifying the public that the Agency has found that the motor vehicle emissions budget (MVEB) for particulate matter less than ten microns (PM-10) for the year 2012 in the Five Percent Plan for PM-10 for the Maricopa County Nonattainment Area (May 2012) ("Five Percent Plan") is adequate for transportation conformity purposes. The Five Percent Plan for PM-10 in the Maricopa County Nonattainment Area was submitted to EPA on May 25, 2012 by the Arizona Department of Environmental Quality (ADEQ) as a revision to the Arizona State Implementation Plan (SIP). As a result of our adequacy findings, the Maricopa Association of Governments (MAG) and the U.S. Department of Transportation must use the MVEB for future conformity determinations.
