Court upholds EPA decision on Arizona coal-fired power plant

Cholla Power Plant

ST. JOHNS, Ariz. (AP) — A federal appeals court has upheld a decision by the U.S. Environmental Protection Agency to replace part of Arizona's plan to cut emissions from power plants.

The 9th U.S. Circuit Court of Appeals ruled Wednesday that the EPA acted reasonably in setting limits for nitrogen oxide emissions at the Coronado Generating Station near St. Johns.

The EPA had said the state's plan for the power plant was flawed in regard to cost and visibility improvement, and inconsistent with haze regulations.

State officials disagreed and asked the appeals court to review the EPA's decision.

The Salt River Project, which operates the generating station, has until December 2017 to comply with the limits.

The EPA had approved other sections of the state's plan for units of the Cholla Power Plant and the Apache Generating Station.
