Oil giant BP has caused yet another oil spill in a crucial water way this week, following an increase in tar sands refining at its Indiana plant on the shores of Lake Michigan.
BP notified the federal government’s National Response Center around 5 p.m. Monday that its Whiting Refinery was leaking oil into the lake, which is the source of drinking water for 7 million people in nearby Chicago, due to a malfunction in the refinery’s cooling water system.

The spill comes less than a year after BP started processing Canadian tar sands at the refinery. Tar sands oil, many environmental groups have warned, is the “the dirtiest fuel on Earth” and is “more corrosive, more toxic, and more difficult to clean up than conventional crude.”
Enumerating a long list of historical problems at the Whiting Refinery, Henry Henderson at the Natural Resources Defense Council notes Wednesday, “The week of the Exxon Valdez disaster anniversary and a week after the Council of Canadians released a report highlighting the threat that tar sands oil imposes on the Great Lakes, BP did what it always does: crapped up Lake Michigan.”
He continues:
“The malfunction occurred at the refinery’s largest crude distillation unit, the centerpiece of a nearly $4 billion overhaul that allowed BP to process more heavy Canadian oil from the tar sands region of Alberta,” reports the Chicago Tribune. “The unit … performs one of the first steps in the refining of crude oil into gasoline and other fuels.”
It was still uncertain Wednesday as to exactly how much of the oil spilled. BP said it had managed to stop the discharge by Tuesday and cleanup efforts continued throughout the day on Wednesday.
