Mining company charged with secretly exposing entire town to asbestos
Prosecutors say that the mine’s owner, W. R. Grace & Company, which is also a defendant, and its managers knew as far back as the 1970s that asbestos was mixed with the vermiculite and that this posed a risk to their workers, but that they conspired to continue releasing it into the air and to misrepresent the peril.
The company’s own medical studies of its miners, the government says, create a paper trail that will prove the charges of wire fraud, obstruction of justice, conspiracy and violations of the Clean Air Act.
