If the leachate is not determined to be a potential pollution problem and if it is agreeable to Cottage Grove then the monitoring of the site would continue on an annual basis or a minimum o5 ~ve years until both 3M and the MPCA were confident that no problem existed with the landfilled material.
If the landfilled material is removed, the area would be restored to conform to the surrounding terrain. Grass would be seeded and natural vegetation would be permitted to grow.
