Taken from the remotely operated vehicle Sunday, April 22, and Monday, April 23, these images show the damage done to two American Transmission Company electric cables, which caused about 600 gallons of insulating oil to leak into the Straits of Mackinac. The cables were severed and capped by the following weekend. Because of the oil’s relatively low toxicity and the dilution of the oil in the water, the Michigan Department of Environmental Quality did not expect any negative effects to nearby drinking water intakes, wildlife, and the environment.
