Officials say it will probably take weeks to clean up 100-thousand gallons of crude oil that spilled from a pipeline Friday night in Superior, Wisconsin. Most of the oil was captured by the ditches and retention ponds at the Enbridge Energy Terminal, but 19,000 gallons made its way onto the frozen Nemadji River. Steve Lee supervises the Minnesota Pollution Control Agency's Emergency Response Team. Lee says transporting oil by pipeline is much safer than moving it on trucks or barges. But, he says, when a pipeline has a problem, the repercussions are large. Lee says that, luckily, a two-foot sheet of ice over the river stopped the oil from getting into the water.
