PAGE, Ariz. -- Arizona could lose $18 billion in gross state product over more than 25 years if a coal-fired power plant in Page shuts down.
That's the finding of an economic impact study of the 2,500-megawatt Navajo Generating Station and the coal mine that feeds it.
The L. William Research Institute at Arizona State University's business school conducted the study at the request of the Navajo Nation and the plant's operator, Salt River Project.
The U.S. Environmental Protection Agency has been considering how to lower nitrogen oxide emissions from the plant.
SRP and the Navajo president have been pushing the EPA to accept low-nitrogen oxide burners as the best way to reduce regional haze.
Conservation groups contend that the plant is an environmental and health hazard that needs upgrades in pollution controls.
