## Abstract

Due to adverse comments, the Environmental Protection Agency (EPA) is withdrawing the direct final rule for "State of Iowa; Approval and Promulgation of the State Implementation Plan, the 111(d) Plan, and the Operating Permits Program," published in the Federal Register on September 15, 2017. Iowa's SIP revision included administrative changes, corrections to technical errors, revisions to titles and explanations of the scope of rules. The revision also rescinded outdated or no longer required rules for general conformity and emissions inventory relating to the Clean Air Interstate Rule (CAIR) which has been rescinded by EPA. Finally, the revision updated state rules by incorporating by reference more recent Code of Federal Regulation dates to ensure consistency between the state and Federally- approved rules.
