Abstract
The Environmental Protection Agency (EPA) is approving revisions to the State Implementation Plan (SIP) for the State of Iowa to include modified permits for Muscatine County, Iowa. The SIP revision addresses modifications to construction permits that were included in the 2006 24-hour particulate matter less than 2.5 micrometers (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) control strategy proposed on August 11, 2014, and published as a final rule in the Federal Register on December 1, 2014, with the effective date of December 31, 2014. The state's submission of modified permits includes a revised air dispersion modeling analysis that demonstrated continued attainment of the 2006 24-hour PM<INF>2.5</INF> NAAQS. This action will also make an administrative correction to permit numbers.
