The U.S. Environmental Protection Agency (EPA) is proposing emissions limits for the 2,250 MW Navajo coal-fired power plant in Arizona.
The proposal calls for the installation of a selective catalytic reduction (SCR) system in combination with low NOx burners previously installed between 2009 and 2011. Both technologies would reduce emissions by 84 percent, or a total of 28,500 tons per year, by 2018.
EPA also proposed giving the plant an additional five years, until 2023, to install new controls.
The Navajo Generating Station is co-owned by the U.S. Bureau of Reclamation, Salt River Project, Los Angeles Department of Water & Power, Arizona Public Service, Nevada Power Co. and Tucson Electric Power.
