On February 24, 2010, the State of Alabama, through the Alabama Department of Environmental Management (ADEM), submitted a request to EPA to make a determination that the Birmingham, Alabama, nonattainment area has attained the 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) based on quality assured, quality controlled monitoring data from 2007-2009. The Birmingham, Alabama, 2006 24-hour PM<INF>2.5</INF> nonattainment area (hereafter referred to as "the Birmingham Area") is comprised of Jefferson and Shelby Counties in their entireties, and a portion of Walker County in Alabama. In this action, EPA is taking final action to determine that the Birmingham Area has attained the 2006 24-hour PM<INF>2.5</INF> NAAQS. This clean data determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2007-2009 showing that the Birmingham Area has monitored attainment of the 2006 24-hour PM<INF>2.5</INF> NAAQS.
