A potential showdown is brewing between state and federal agencies over the U.S. Coast Guard’s longstanding practice of allowing freighters to wash unlimited amounts of coal and other cargo residues into the Great Lakes.
Each year, the Great Lakes shipping fleet washes upwards of two million pounds of cargo residue — primarily coal, limestone and iron ore — off freighters and into the lakes. The practice, used since the 1930s, prevents cargo residues from contaminating subsequent loads of other materials.
Federal law and an international treaty prohibit ships from dumping waste into the Great Lakes. But the practice has continued because Congress in 1993 approved a temporary policy, a loophole essentially, that allowed it on an interim basis. The Coast Guard now wants to make that policy permanent.
… “Minnesota solid waste rules prohibit the disposal of solid waste into waters of the state of Minnesota, including Lake Superior,” said Paul Eger, assistant commissioner of the Minnesota Pollution Control Agency, in a letter to the Coast Guard.
Eger disputed the Coast Guard’s claim that cargo residues washed off ships sink quickly and do not harm water quality.
“Coal has been observed and collected by the Minnesota Pollution Control Agency on the shoreline beach of Minnesota Point, Duluth,” Eger said. “This coal did not dissolve or dissipate in the waters of the lake, but instead floated and accumulated along the beach in Duluth.”
Michigan officials said they were unaware freighter operators washed cargo residues into the lakes until 2006, when The Chronicle first reported on the practice.
“Such discharges appear to be in violation of Michigan’s Natural Resources and Environmental Protection Act,” said Rich Powers, chief of the Michigan Department of Environmental Quality’s Water Bureau, in a letter to the Coast Guard.
