Abstract
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 (PM<INF>2.5</INF>) 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 PM<INF>2.5</INF> 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 PM<INF>2.5</INF> NAAQS.
