SAVANNAH, Ga. AP – Federal officials proposed more than $8.7 million in fines Friday against Imperial Sugar Co. for violations at a Georgia plant where an explosion this year killed 13 people and at another plant in Louisiana.

The fines would be the third-highest in the history of the Occupational Safety and Health Administration and include $5 million for the explosion near Savannah and $3.7 million for the plant in Gramercy, La., where authorities found violations a month after the Feb. 7 blast in Georgia that injured dozens of workers.
