DIXFIELD, Maine — A fire at the Irving Forest Products sawmill in Dixfield caused heavy damage to part of a building Saturday, according to the Dixfield Fire Company. No one was hurt. “The damage is extensive but contained to the northwest side of the sawmill building,” the fire company said in a statement. “Mill personnel are assessing damage and already planning repairs.” Firefighters from several towns — including Rumford, Peru, Mexico, East Dixfield, Jay, Wilton, Canton, Roxbury and Carthage — helped battle the blaze, according to the department. Irving Forest Products bought the Dixfield sawmill in 1998 and has invested more than $40 million into the mill. The Maine State Fire Marshal’s Office is investigating. [END]
