Topeka ? Legislative leaders expect votes Thursday on a bill allowing two coal-fired power plants in southwest Kansas.

The Senate will be the first to take up the compromise drafted by negotiators for the two chambers. It will be an up-or-down vote, then the House will do the same.

Approval in both chambers, which is expected, would send the measure to Gov. Kathleen Sebelius. She opposes it.

So does Lt. Gov. Mark Parkinson, who would become governor if Sebelius is confirmed as U.S. secretary of health and human services.

The bill reverses a decision by Sebelius’ administration in October 2007 to deny an air-quality permit to Sunflower Electric Power Corp. The Hays-based utility wants to build the two plants in Finney County.
