The state of Wyoming has challenged EPA’s rights to take over greenhouse gas permitting in the state. A federal court ruled that the decision should be made by the U.S. District Court of Appeals, so it will be transferred there rather than the Denver-based 10th Circuit U.S. Court of Appeals like Wyoming desired. Wyoming’s case focuses on the EPA’s state implementation plans(SIP’s) which calls for states to prove that they can oversee greenhouse gas emissions through their state air-pollution programs. The states that lacked this ability under their current SIP, must implement a federal plan or let the EPA take over. The DC Circuit court, which handles a number of regulation disputes, already has a similar case on its plate involving the state of Texas. As the court moves forward don’t be surprised if the cases end up being dealt with at the same time.
