The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will significantly contribute to nonattainment or interfere with maintenance of air quality in other states. The State of Iowa made a submission to the Environmental Protection Agency (EPA or Agency) to address these requirements for the 2015 ozone National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve the submission for Iowa as meeting the requirement that the SIP contains adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state. The EPA is also withdrawing its previous proposed rule to approve Iowa's SIP submission, as published in the Federal Register on March 2, 2020.
The agency’s own summary, as published.
