Summary

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 (PM<INF>2.5</INF>) unclassifiable area (hereinafter referred to as the "Etowah County Area" or "Area") to attainment for the 2006 primary and secondary 24-hour PM<INF>2.5</INF> national ambient air quality standards (NAAQS). EPA now has sufficient data to determine that the Etowah County Area is in attainment of the 2006 primary and secondary 24-hour PM<INF>2.5</INF> NAAQS. Therefore, EPA is proposing to approve the State's request and redesignate the Area to unclassifiable/ attainment for the 2006 primary and secondary 24-hour PM<INF>2.5</INF> NAAQS based upon valid, quality-assured, and certified ambient air monitoring data showing that the PM<INF>2.5</INF> monitor in the Area is in compliance with the 2006 primary and secondary 24-hour PM<INF>2.5</INF> NAAQS.
