Minnesota officials call it a dirty practice that’s fouling Lake Superior, but ships carrying coal and taconite likely will continue “sweeping’’ their waste cargo into the Great Lakes.
The U.S. Coast Guard is about to approve a new regulation giving Great Lakes freighters a permanent pass on dumping some 2 million pounds of bulk cargo residue overboard each year.
U.S. laws and an international treaty prohibit ships from dumping waste into the Great Lakes or within 12 miles of shore in the ocean. But Congress in 1993 approved a temporary exemption continuing the practice of sweeping excess taconite pellets, coal and limestone into the Great Lakes.
In 2004, after a series of temporary exemptions, Congress extended the sweepings exemption through Sept. 30, 2008, and ordered the Coast Guard to study the issue and come up with a permanent plan.
The agency is scrambling to get a regulation in place by that deadline. If a permanent rule isn’t in place by Sept. 30, the Coast Guard technically would be required to fine Great Lakes ships for dumping any material into the lake.
… Great Lakes ship crews for at least 70 years have been “sweeping’’ or washing leftover bulk material overboard to keep from contaminating future loads of other materials and to keep their decks and equipment clean.
Shipping companies say they can’t operate without sweeping their ships and that regulations to dispose of the materials on land would be too costly.
… Ship owners claim the amount of cargo washed overboard is harmless and just a small fraction of the 165 million tons of cargo shipped on the lakes each year.
“The amount of dry cargo residue being washed down is truly minute,’’ said James H.I. Weakley, president of the Cleveland-based Lake Carriers Association, in comments to the Coast Guard. The group represents 63 U.S. freighters.
