Approval and Promulgation of Air Quality Implementation Plans; Washington; Determination of Clean Data for the 2006 24-Hour Fine Particulate Standard for the Tacoma, Pierce County Nonattainment Area
EPA is making a final determination that the Tacoma, Pierce County nonattainment area (hereafter referred to as ``Tacoma, Pierce County'' or ``the area'') has clean data for the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality- assured, quality-controlled, and certified ambient air monitoring data showing that the area has monitored attainment of the 2006 PM2.5 NAAQS based on the 2009-2011 data available in EPA's Air Quality System (AQS) database. EPA's determination relieves the area from the requirements to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the standard for so long as the area continues to meet the 24-hour 2006 PM2.5 NAAQS.
