(SFGate) — The U.S. Environmental Protection Agency has issued its final rule...Rather than mandate that the Four Corners Power Plant take one avenue to reducing nitrogen oxide emissions, the EPA is giving the plant's operators a choice, regional administrator Jared Blumenfeld told The Associated Press on Wednesday. Arizona Public Service can either upgrade the five units at the northwestern New Mexico plant or go with its own plan to shut down three units and install pollution controls at the two others.
The actions would cut emissions that can worsen visibility at national parks like the Grand Canyon by 80 percent and 87 percent, respectively.
"It's a commonsense approach that will result in a significant decrease in pollution in spectacular parks like Mesa Verde and Canyonlands, which are crucial to the economy of Four Corners," Blumenfeld said. "And it will improve visibility and clean the air that we breathe."
