Ash Grove Cement Co plans to start allowing workers return to its Montana City works, after a voluntary shutdown triggered by concern about asbestos.
Operations were closed abruptly on March 16 after a company geologist suspected tremolite asbestos in rock at the Ash Grove quarry.
The March 16 closure sent 57 hourly employees home with pay. The Montana Department of Environmental Quality said testing involved more than 200 samples collected by Ash Grove, DEQ and the U.S. Mine Safety and Health ; Administration.
