## Abstract

EPA has determined that the Bullhead City and Payson moderate PM-10 nonattainment areas in Arizona and the Sacramento and San Bernardino moderate PM-10 nonattainment areas in California have attained the National Ambient Air Quality Standard (NAAQS) for Particulate Matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10) by the applicable December 31, 2000, attainment date. This determination is based upon monitored air quality data for the PM-10 NAAQS during the years 1998-2000. This determination of attainment does not redesignate the Bullhead City, Payson, Sacramento and San Bernardino areas to attainment for PM-10. The Clean Air Act requires that, for an area to be redesignated, five criteria must be satisfied including the submittal of a maintenance plan as a State Implementation Plan (SIP) revision. This action also corrects the effective date listed for the moderate nonattainment classification for Bullhead City.
