CHEYENNE – The State of Wyoming, through the Attorney General, filed a reply brief in the United States Court of Appeals for the 10th Circuit in its case challenging the EPA’s attempt to expand the boundaries of the Wind River Indian Reservation.

The EPA’s decision declared areas of Wyoming, including the City of Riverton, part of the Reservation – a decision Wyoming appealed.

“The State’s latest brief clearly outlines that in 1905 Congress intended to reduce the size of the Reservation. One cannot create ambiguity out of that clarity and attempts by the EPA and Tribes to do so should fail,” Governor Matt Mead said.

Wyoming has asked the United States Court of Appeals for the Tenth Circuit to set aside the EPA’s decision and require the EPA to reconsider the Tribes’ application for treatment as a state under the Clean Air Act, using the appropriate law and facts.

The State of Wyoming has made its brief available to the public on the Attorney General’s website at: http://ag.wyo.gov/current-issues.
