PHOENIX — A federal appeals court has rejected a bid to postpone pollution
control upgrades at three Arizona coal-fired power plants.
The state and four utility companies had asked the 9th Circuit U.S. Court of
Appeals for the delay while the court reviews the U.S. Environmental Protection
The court denied the request in a brief order this week.
The EPA partially approved Arizona’s air quality plan for the Cholla, Coronado
and Apache generating stations. But the agency said the state didn’t do enough
to control nitrogen oxide emissions. The plants’ operators have five years to
comply with set limits.
State Department of Environmental Quality Director Henry Darwin has said
Arizona should be making decisions about what’s in the best interest of the
state, not the EPA.
