SARTELL -- The buyers of the closed Sartell paper mill will likely have to have an environmental assessment done on the property as part of any redevelopment plans.

The 104-year-old mill has had machines there nearly the entire time and questions need to be answered on what types of pollution may exist on that site.

Minnesota Pollution Control Redevelopment Program Supervisor Hans Neve says those questions will get answered and shouldn't pose any risk to redeveloping that site.

Neve says no one knows what the possible pollutants exist on the site until they take samples of the soil and water. He says it's tough to put a cost on any cleanup costs, if any, until they have more information.
