Investigators have said that disaster - which killed 14 people and hurt many others who were treated at Augusta's Joseph M. Still Burn Center - and the Sugar Land mishap were fueled by big buildups of sugar dust.

They also are pressing the government's case for $8.8 million in fines for more than 200 alleged safety violations at Port Wentworth and the company plant in Gramercy, La.
Imperial is appealing.
