OTSEGO (WKZO) -- Tests are underway to determine whether hazardous materials had been stored for years under the former Rock-Tenn paper mill in Otsego.
County officials were doing an environmental assessment of the property, when they found two-hundred barrels filled with chemicals stored in the basement of the plant. They also found plastic totes and other containers that had chemicals in them.
The U.S. Environmental Protection Agency was called to the site. An EPA investigator says most of the drums and containers are either lacking labels or mislabeled. They are going through plant records to try and determine what might have been used in the paper manufacturing process.
The plant closed in 2004.
