FILE - This Feb. 17, 2010 file photo shows the town of 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. Attorneys and scientists for W.R. Grace Inc., which operated an asbestos mine in Libby for three decades, say the EPA proposal would frustrate cleanup efforts by setting an unattainable standard for exposures.
