The parent company of the paper mill in Rumford, Maine, has filed its reorganization plan 11 months after seeking Chapter 11 bankruptcy protection. Ohio-based NewPage Corp. said Tuesday that the plan was filed in federal bankruptcy court in Delaware. George Martin, president and CEO, described the filing as “an important and positive step forward to a successful completion of our financial reorganization.” He said he hopes ongoing negotiations with major creditors will lead to broad support for the plan. NewPage has about 900 employees in Rumford. Besides Maine, NewPage owns paper mills in Kentucky, Maryland, Michigan, Minnesota, Wisconsin and Nova Scotia with $3.5 billion in net sales last year.
