FLAGSTAFF, Ariz. (AP) — Requiring a coal-fired power plant on the Navajo Nation to further regulate nitrogen oxide emissions alone would not force its retirement.
But it would significantly increase water rates for agricultural users and American Indian tribes.
Those are some of the findings in a study released Wednesday by the U.S. Department of Interior.
The U.S. Environmental Protection Agency has been considering how to lower haze-causing emissions from the Navajo Generating Station near Page.
The Central Arizona Project uses power from the plant to deliver water through a series of canals to 80 percent of the state’s population. It also ensures that water rights settlements with tribes are met.
The study says a significant increase in the cost of power from the plant would affect settlements with some tribes.
