WOODBURY, Minn. (AP) - The Minnesota Pollution Control Agency has approved a cleanup plan for a 40-year-old 3M dump site in suburban St. Paul.

The company dumped industrial waste over about 20 acres on the border of Woodbury and Cottage Grove from 1960-66. Adhesive, rolls of film, rags, resins and more than 400,000 gallons of waste generated from making Scotch tape and sandpaper were dumped at the site.

The MPCA approved the cleanup on Tuesday. The plan calls for hauling contaminated soil to a site in Rosemount and removing and filtering groundwater.

3M agreed to cleanup three of the dumps it owned that were believed to have contaminated groundwater in some parts of Washington County. But the Minnesota Health Department later determined there was little health risk.
