Three days after spilling crude oil into Lake Michigan, BP has doubled its spill estimate to between 470 and 1228 gallons. The leak happened at its refinery in Whiting, Ind.
Although some of the oil has been cleaned up, it's unclear how much is left in the lake, a drinking water source for about seven million Chicagoans.
Located just across the Illinois-Indiana state border, Whiting is home to the sixth largest refinery in the U.S. The refinery just went through a $4 billion “modernization project,” giving it “the capability of processing up to about 85 percent heavy crude.” That's up from its original 20 percent, says BP's website.
“Frigid temperatures caused some of the oil to harden into a waxy consistency that made it easier to collect,” BP spokesman Scott Dean told The Chicago Tribune. “Crews used vacuum trucks to suck up any liquid oil that washed ashore.”
The day after the spill, U.S. Sen. Dick Durbin (D-IL) and U.S. Sen. Mark Kirk (R-IL), as well as U.S. Sen. Debbie Stabenow (D-MI) and U.S. Sen. Carl Levin (D-MI) issued press releases in which they pledged to hold BP accountable for the spill. Durbin and Kirk also wrote a follow-up letter to BP, requesting a meeting with BP.
“Any unanticipated spill is cause for concern, but given the Whiting refinery’s recent expansion of its operations to double the amount of heavy oil sands being processed, this spill raises questions about the long-term safety and reliability of BP's new, expanded production at Whiting,” they wrote.
