Cheyenne, WY (AP) - The State of Wyoming wants a federal appeals court to review a determination by the U.S. Environmental Protection Agency that lands around Riverton remain legally Indian Country.
The Wyoming Attorney General's Office on Friday asked the U.S. 10th Circuit Court of Appeals in Denver to review a decision the EPA announced in December.
The EPA concluded a 1905 federal law opening over 1 million acres of the Wind River Indian Reservation to settlement by non-Indians didn't extinguish the land's reservation status.
Wyoming Gov. Matt Mead has blasted the EPA decision. Mead says it's up to Congress to determine reservation boundaries.
The EPA announced on Thursday that it would stay its decision pending court review. The Northern Arapaho and Eastern Shoshone tribes had joined with the state in requesting the stay.
