Air Plan Approval; Iowa; Air Quality Implementation Plan-Muscatine Sulfur Dioxide Nonattainment Area and Start-up, Shutdown, Malfunction SIP Call Withdrawal
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision, submitted by the state of Iowa, through the Iowa Department of Natural Resources (IDNR), to the EPA on May 26, 2016, for the purpose of providing for attainment of the 2010 1-hour primary Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS) in the Muscatine County, Iowa nonattainment area (NAA). The EPA concludes that Iowa has appropriately demonstrated that its SIP provides for attainment with the 2010 1-hour primary SO2 NAAQS in the NAA, and that the plan meets the other applicable requirements under the Clean Air Act (CAA or Act). As a part of approving the attainment demonstration, the EPA is taking final action to approve into the Iowa SIP the SO2 emissions limits and associated compliance parameters for the NAA. The EPA is also applying a policy regarding startup, shutdown, and malfunction (SSM) exemption provisions in the Iowa SIP that is consistent with the EPA's national policy. In light of this policy and the EPA's evaluation of Iowa's SIP, the EPA is withdrawing the SIP call issued to Iowa as part of the EPA's 2015 SSM SIP Action.
