## Abstract

In this document EPA is making a final finding that the Phoenix Planning Area (PPA) has not attained the PM<INF>10 (particulate matter 10 microns or less in aerodynamic diameter) national ambient air quality standards (NAAQS) by the applicable attainment date in the Clean Air Act (CAA) for moderate PM<INF>10 nonattainment areas, December 31, 1994. This finding is based on EPA's review of PM<INF>10 ambient air quality data. As a result of this finding, the PPA is reclassified as a serious PM<INF>10 nonattainment area by operation of law. The intended effect of the reclassification is to allow the State 18 months from the effective date of this action to submit a new State Implementation Plan (SIP) demonstrating attainment of the PM<INF>10 NAAQS by December 31, 2001, the CAA attainment date for serious areas.
