Cleaning up Minnesota Slip - containing 2500 cubic yards of contaminated sediment and sealing it off - isn't the hard part.

Nor is repairing the dock walls lining the slip.

Not even getting the  610 feet by 60 feet by 32 foot SS William A Irvin out of the way so it can undergo some needed maintenance the hard part.

The hard part is figuring out how to do it at the same time.
