Wyoming has joined 23 states in suing to stop the Environmental Protection Agency's Clean Power Plan, which sets limits on emissions from coal-fired power plants.

The final rule, which was published in the Federal Register Friday morning, imposes a 44% carbon emission reduction requirement on Wyoming, more than doubling the 19% reduction in the EPA's proposed rule.

"I have said from the get-go that this rule is legally and scientifically flawed. We do not believe the EPA has the authority for this rule," said Governor Matt Mead.  "The fact that the agency more than doubled the damage to Wyoming in the final rule shows arbitrary and capricious action."

The coalition of states is also asking for an administrative stay on the ruling, which would halt any implementation of the Clean Power Plan during litigation.

"We will be continuing to fight it in every way we can," said Governor Mead. "At this point we are looking and hopefully are going to get a favorable decision in getting a stay on the rule itself."

Wyoming also plans to file a petition with the EPA to reconsider the rule in light of state-specific issues.
