The Environmental Protection Agency (EPA) is taking final action to partially approve and partially disapprove elements of the State Implementation Plan (SIP) submission from the State of Iowa addressing the applicable requirements of the Clean Air Act (CAA) section 110 for the 2008 ozone NAAQS. Section 110 requires that each state adopt and submit a SIP to support 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.
