WASHINGTON – Power plants on Navajo Nation land need more time to meet new emissions standards or they could be forced to close, throwing thousands of Navajo out of work and costing the tribe millions, an official said Wednesday.

The number of American Indians who claimed to be multiracial jumped sharply over the last decade, but not so much in Arizona, the Census Bureau reported Wednesday.

Gila River Indian Community residents are scheduled to vote Feb. 7 whether to allow the South Mountain Freeway extension on tribal land.

The Tohono O’odham Nation has relied on a few impressive numbers in its pitch for a casino on a tract of unincorporated land surrounded by Glendale: 6,000 construction jobs and 3,000 permanent jobs.

Navajo Nation President Ben Shelly told a Senate committee Thursday that the Environmental Protection Agency “ignores reality” by insisting on the most-advanced pollution control technology to update coal-fired power plants.

With Congress required to come up with more than $1 trillion in multiyear budget cuts this fall, tribal leaders converged in Washington this week to make sure their concerns are included in the discussion.

A federal judge has removed a hurdle for people challenging the U.S. government’s $3.4 billion settlement of an Indian land mismanagement lawsuit, the largest government settlement in U.S. history.

Supporters and opponents of a proposed casino in Glendale accused each other of subverting the system Tuesday as they clashed on a bill that would prevent the Tohono O’odham Nation from building the project.

The chairman of the Hopi Tribe says it makes sense to place its reservation in the same congressional and legislative districts as the larger Navajo Reservation that surrounds it.

The Hopi Tribe has followed up on a threat to sue the city of Flagstaff for maintaining a contract to sell treated wastewater for snowmaking at an Arizona ski resort.
