The OMA led a collation of business groups in supporting the Ohio EPA’s removal of an Air Nuisance Rule (ANR) from the state’s federally approved air plan. The ANR was mistakenly added to the Ohio’s federal plan decades ago and has no connection to federal air quality standards, subjecting manufacturers to meritless citizen suits and regulatory uncertainty.

The rule’s removal is mandated by a provision in state law secured through the OMA’s advocacy efforts. Ohio EPA will now begin the process of seeking federal approval to remove the rule from Ohio’s air plan. The OMA will continue to work closely with Ohio EPA to support this federal approval process. 10/9/2025
