"The ruling could complicate EPA’s “good neighbor” rules that aim to clamp down on pollution that crosses state borders."
"The Supreme Court on Wednesday sided with two Republican states on a venue question that could hamper future EPA efforts to combat dangerous air pollution that crosses state lines.
The case pertained to a crucial procedural underpinning of the agency’s 2023 federal “good neighbor” plan that sought to strengthen limits on smog-forming emissions from coal-fired power plants and other industries in 23 states.
In its 8-0 opinion, the high court found that states can contest EPA’s earlier decision to first disapprove state “good neighbor” plans in regional appellate courts instead of the U.S. Court of Appeals for the District of Columbia Circuit, which is the usual venue for bringing challenges to nationally applicable rules."
