The state Court of Appeals has been asked to strike down an air-quality permit for a new coal-fired power plant in southwest Kansas.

The request was filed by the Sierra Club yesterday in Topeka. It asks the court to set aside the permit issued last month by the Kansas Department of Health and Environment to Sunflower Electric Power Corp.

The Hays-based utility plans to build the new power generator at

its plant near Holcomb, in Finney County .

Sierra Club attorneys want the court to issue an injunction stopping Sunflower from building the generator until another permit can be issued.

The group argues in part that flawed environmental data were used in the permitting process.
