Imperial Sugar Co. agreed to pay $6 million in fines over safety violations following the February 2008 explosion in a Georgia plant that killed 14 people.

Imperial Sugar says it added numerous safety features when it rebuilt the Georgia plant last year. The settlement with OSHA also requires the company to maintain an improved housekeeping program, employ a full-time safety manager for the Georgia plant and undergo audits by outside safety experts for the next three years.

Imperial Sugar agreed to pay $4.05 million in fines for 124 safety violations, including 69 willful violations, at its Georgia refinery. The company will pay an additional $2 million in fines for 97 violations OSHA found at its Louisiana plant during inspections after the Georgia explosion.

Imperial Sugar’s chief financial officer, H.P. Mechler, said the company has improved its employee training program and overhauled its cleanup practices to ensure better control of sugar dust. “I don’t think anyone in the industry, including ourselves, were fully aware of the potential of dust as a hazard,” Mr. Mechler said. Imperial Sugar still faces 36 civil lawsuits, including suits by families of those killed and some of the 40 people injured, as well as a handful of shareholder suits, according to its most recent quartely results.
