The Ohio Manufacturers’ Association (OMA) submitted comments this week supporting Ohio EPA’s effort to reinstate the emergency affirmative defense provision in Ohio’s Title V air permitting rules. The move follows a D.C. Circuit Court decision reversing U.S. EPA’s removal of the narrow defense from federal operating permit regulations.
The provision helps protect facilities from liability when an emissions exceedance results from a true emergency, not routine operations or poor planning. OMA said reinstating the defense would provide greater operational certainty and reduce the risk of costly enforcement disputes tied to circumstances outside a facility’s control. OMA also requested to remain involved as Ohio EPA develops proposed rule language.
“Manufacturers should not face unnecessary liability when a true emergency, outside their control, causes an emissions exceedance,” said James Lee, OMA managing director of public policy services. “Ohio EPA’s action restores a narrow, commonsense safeguard while maintaining strong environmental protections and accountability.” 5/11/2026
