Asbestos Town

FILE - In this April 28, 2011 file photo, unidentified road workers wear protective gear against possible asbestos contamination as they load material from a road resurfacing project in downtown Libby, Mont. W.R. Grace, Inc., the chemical company blamed for polluting Libby, Mont. with asbestos dust that has killed hundreds of people, is pushing back against the Environmental Agency proposal and seeking to have it revised. A cleanup proposal for a Montana town where thousands have been sickened by asbestos exposure calls for leaving some of the dangerous material in place rather than removing it.
