Abstract
Pursuant to the Environmental Protection Agency's (EPA) authority in the Clean Air Act (CAA or Act), section 110(k)(5), to call for plan revisions, EPA is making a finding that the Iowa State Implementation Plan (SIP) is substantially inadequate to maintain the 2006 24-hour National Ambient Air Quality Standard (NAAQS) for Fine Particulate Matter (PM<INF>2.5</INF>) in Muscatine County, Iowa. The specific SIP deficiencies needing revision are described below. EPA is also finalizing a timeline for Iowa to revise its SIP to correct these deficiencies by a date which is no later than 18 months after the effective date of this rule.
