## Abstract

EPA is finalizing a determination that the Paul Spur/Douglas nonattainment area in Arizona is currently attaining the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter of less than or equal to a nominal ten micrometers (PM<INF>10</INF>) based on certified, quality-assured ambient air monitoring data for the years 2009-2011. Given our determination that the Paul Spur/Douglas nonattainment area is currently attaining the PM<INF>10</INF> NAAQS, EPA is also determining that Arizona's obligation to make submissions to meet certain Clean Air Act requirements related to attainment of the NAAQS is not applicable for as long as the Paul Spur/Douglas nonattainment area continues to attain the NAAQS and that the obligation on EPA to promulgate a Federal Implementation Plan to address the State's attainment-related requirements is also suspended for as long as Arizona's underlying obligation is suspended.
