AK Steel is receiving some praise from an unlikely source. The Sierra Club has criticized the steelmaker over air and water pollution issues in the past. Now the environmental watchdog group is praising AK's recent moves to improve community relations. Ray Agee of Oneida is a former AK employee and one of its frequent critics. He says new president and CEO James Wainscott has made a difference. Company spokesman Alan McCoy says they're pleased the Sierra Club has noticed their efforts. AK Steel has established a complaint line and encouraged residents to call about problems with ash. It also is installing new controls designed to limit emissions. The company has steelmaking operations in Ohio, Kentucky, Indiana and Pennsylvania.
