A panel of appellate judges in Atlanta pressed lawyers for the Environmental Protection Agency and Hunt Refining Co. over the correct venue for the oil company’s challenge to its denied bid for exemptions from federal renewable fuel standards.

Alabama-based Hunt Refining filed its challenge to the EPA’s 2022 action in the U.S. Court of Appeals for the Eleventh Circuit, but the agency argues its decision was “nationally applicable” and therefore, under the Clean Air Act, belongs in the D.C. Circuit.
