Abstract
EPA is finalizing a determination that the Ogden City nonattainment area in Utah is currently attaining the 24-hour 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 through 2011. The State of Utah submitted a letter dated March 30, 2000, requesting EPA to make a clean data determination for the nonattainment area of Ogden City. Given our determination that the Ogden City nonattainment area is currently attaining the PM<INF>10</INF> NAAQS, EPA is also determining that Utah's obligation to make submissions to meet certain Clean Air Act (CAA) requirements related to attainment of the NAAQS is not applicable for as long as the Ogden City nonattainment area continues to attain the NAAQS. This action is being taken under the CAA.
