"Federal judges wrestled today with whether U.S. EPA ran afoul of the law in directing states to implement regulations to address climate change."
"At issue before a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit are two cases that challenge EPA's interactions with states after the agency finalized landmark greenhouse gas rules in 2010.
EPA had sought to make sure states that had Clean Air Act permitting authority for new major facilities were able to adequately take into account greenhouse gas emissions."
