Abstract
In this notice, EPA is revising the PM<INF>10 (particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers) National Ambient Air Quality Standards (NAAQS) designation for Ogden City, a portion of Weber County, Utah. Previously, consistent with section 107(d)(3)(A) of the Act, EPA notified the Governor of Utah that Weber County, Utah should be redesignated from unclassifiable to nonattainment for PM<INF>10. The redesignation is based upon violations of the PM<INF>10 NAAQS which were monitored between January 1991 and January 1993.
