Abstract
EPA is approving a state implementation plan revision submitted by the Arizona Department of Environmental Quality to address the moderate area PM<INF>10</INF> (particulate matter with an aerodynamic diameter of less than or equal to a nominal ten micrometers) planning requirements for the Nogales nonattainment area. Consistent with this final action, EPA is approving the following plan elements as meeting the requirements of the Clean Air Act: The Nogales nonattainment area 2008 and 2011 emission inventories; the demonstration that the Nogales nonattainment area is attaining the National Ambient Air Quality Standard for PM<INF>10</INF>, but for international emissions sources in Nogales, Mexico; the demonstration that reasonably available control measures sufficient to meet the standard have been implemented in the nonattainment area; the reasonable further progress demonstration; the demonstration that implementation of measures beyond those needed for attainment meet the contingency measure requirement; and, the motor vehicle emissions budget for the purposes of determining the conformity of transportation plans, programs, and projects with this PM<INF>10</INF> plan.
