PAGE, Ariz. -- The U.S. Environmental Protection Agency is sifting through more than 70,000 comments on proposals to control pollution from a coal-fired power plant on the Navajo Nation.
The agency planned to issue a final rule this year for the Navajo Generating Station near Page.
The EPA has proposed cutting haze-causing nitrogen oxide emissions at the plant by 84 percent. The proposal would give the power plant's owners 10 years to install technology aimed at improving visibility at places such as the Grand Canyon.
A group that included the plant's operator has submitted an alternative plan that would involve shutting down one of the three 750-megawatt units. It also set a firm deadline for shutting down the largest coal-fired power plant in the West by 2044.
The public comment period ended Monday.
