Grede Foundry and three supervisors have been indicted for allegedly obstructing an investigation into asbestos exposure to workers at the company's now-shuttered facility in Berlin.
The seven-count indictment alleges conspiracy, obstruction and false statements.
The case involves a January 2012 incident in which foundry workers allegedly were given inadequate safety equipment and not informed they were dealing with asbestos while working on equipment.
The company in a statement didn't comment on the indictment, citing the ongoing legal case.
But it said the health and safety of its workers is a top priority and the company strives to follow all laws and regulations.
If convicted, the supervisors could face prison time and hundreds of thousands of dollars in fines.
The corporation could face millions of dollars in criminal penalties.
