TOPEKA, Kan. (AP) — A Kansas Department of Health and Environment spokeswoman says the agency believes a new coal-fired power plant in the southwest part of the state would comply with all federal and state air-quality laws. KDHE spokeswoman Sara Belfry made the statement Friday after the Sierra Club filed a new lawsuit with the state Court of Appeals over the $2.8 billion project proposed by Hays-based Sunflower Electric Power Corporation. KDHE Secretary Robert Moser last month approved changes in a 2010 permit to allow construction of the 895-megawatt plant outside Holcomb. The changes were necessary because of a Kansas Supreme Court ruling last year in an earlier Sierra Club lawsuit. The Sierra Club contends even with the changes the plant wouldn't comply with federal clean-air rules.
