The Environmental Protection Agency (EPA) is proposing to approve elements of two State Implementation Plan (SIP) submissions from the State of Iowa for the Infrastructure SIP Requirements for the 1997 and 2006 Fine Particulate Matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS). Infrastructure SIPs address the applicable requirements of Clean Air Act (CAA) section 110, which requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by the EPA. These SIPs are commonly referred to as "infrastructure" SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. This action also proposes to approve the adoption of the 1997 PM<INF>2.5</INF> standard. On September 8, 2011, EPA issued a Finding of Failure to Submit a Complete State Implementation Plan for several states, including Iowa. With respect to Iowa, the Finding of Failure to Submit covered the following 2006 PM<INF>2.5</INF> NAAQS infrastructure requirements: 110(a)(2)(A)-(C), (D)(i)(II) (prong 3 only), (E)-(H) and (J)-(M). This proposal to approve Iowa's infrastructure SIP for the 2006 PM<INF>2.5</INF> NAAQS addresses the September 8, 2011 finding.
