(Riverton, Wyo.) – With several articles beginning to circulate nationally about the Environmental Protection Agency’s Clean Air Act ruling putting Riverton within the boundaries of the Wind River Indian Reservation, we thought we’d lay out some of the basic facts.
In a very small nutshell, the EPA ruled in December that the Eastern Shoshone and Northern Arapaho Tribes of the Wind River Indian Reservation have “state status” for the purposes of air quality monitoring within their borders, and they also have an opportunity to comment on projects within 50 miles of the exterior boundaries of the reservation.
In its ruling, the EPA put Riverton, Kinnear and Pavillion inside the reservation’s boundaries, despite 1905 congressional action designating the borders and past court rulings to the contrary.
The ruling’s Federal Register listing is at this link, and from there hundreds of documents used in coming to the decision, including the boundary issue, can be found.
