Ash Grove Kansas obtains Haz-waste permit renewal

A Hazardous Waste Permit renewed by the Kansas Department of Health and Environment (KDHE) and U.S. Environmental Protection Agency Region 7 allows Ash Grove Cement’s Chanute facility to continue container and tank storage, plus kiln burning, of hazardous waste. Issued pursuant to a comprehensive technical review and a late-2009 public hearing, followed by minor modifications to a preliminary draft, the renewed permit also contains technical and regulatory requirements targeting public health and environmental protection. Ash Grove began burning hazardous waste as fuel in 1988 and built a new kiln system in 2000, tripling clinker production without significant change in the alternative fuel consumption.
