## Abstract
On March 22, 2018, the State of Alabama, through the Alabama Department of Environmental Management (ADEM), submitted a request for the Environmental Protection Agency (EPA) to redesignate the Etowah County, Alabama fine particulate matter (PM2.5) unclassifiable area (hereinafter referred to as the "Etowah County Area" or "Area") to attainment for the 2006 primary and secondary 24-hour PM2.5 national ambient air quality standards (NAAQS). EPA is approving the State's request and redesignating the Area to unclassifiable/attainment for the 2006 primary and secondary 24-hour PM2.5 NAAQS based upon valid, quality-assured, and certified ambient air monitoring data showing that the PM2.5 monitor in the Area is in compliance with the 2006 primary and secondary 24-hour PM2.5 NAAQS.
