## Abstract

EPA is taking final action to determine that the West Central Pinal nonattainment area in Arizona has attained the 2006 24-hour fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality-assured, and certified ambient air monitoring data showing that this area has monitored attainment of the 2006 24-hour PM<INF>2.5</INF> NAAQS based on the 2010-2012 monitoring period. Based on the above determination, the requirements for this area to submit an attainment demonstration, together with reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures for failure to meet RFP and attainment deadlines are suspended for so long as the area continues to attain the 2006 24-hour PM<INF>2.5</INF> NAAQS.
