EPA Wants Big Changes At NM Power Plant

New Mexico – The U.S. Environmental Protection Agency is proposing pollution controls that would mean an 80 percent reduction in nitrogen oxides from the Four Corners Power Plant on the Navajo Nation in northwestern New Mexico.

The EPA says that would reduce emissions of nitrogen oxides from about 45,000 tons per year to 9,000 tons per year, and improve public health and visibility at 16 national park sites in the area.

EPA officials say the proposal will require the operator, Arizona Public Service Company, to install selective catalytic reduction on the plant's five units.

The agency says it's the most stringent pollution control technology available for that type of facility.

The administrator of EPA's Region 9, Jared Blumenfeld, says the Four Corners plant is the largest single source of nitrogen oxides in the United States.
