OKLAHOMA CITY (June 18, 2025) – Attorney General Gentner Drummond said today he is grateful the U.S. Supreme Court agreed that he is able challenge the EPA’s rejection of Oklahoma’s “Good Neighbor” state implementation plan at the Tenth Circuit, not the D.C. Circuit. In March 2023, Oklahoma had challenged the EPA action in the U.S. Court of Appeals for the Tenth Circuit, but that court transferred the case to the D.C. Circuit.
In Oklahoma v. Environmental Protection Agency, the justices unanimously supported Oklahoma’s position that the case should be returned to the Tenth Circuit
“The EPA action, taken under the Biden-Harris Administration, was federal overreach of the first order,” Drummond said. “Federal bureaucrats rejected the work and expertise of our own Department of Environmental Quality and instead sought to shackle Oklahoma with a one-size-fits-all plan with a litany of onerous emissions requirements. State sovereignty was under constant attack by the previous occupant of the White House, and the EPA was only too happy to oblige.”
Oklahoma’s DEQ had created the “Good Neighbor” state implementation plan to ensure compliance with Clean Air Act requirements that address emissions contributing to ozone levels downwind.
