BP’s newly upgraded refinery just spilled oil into Chicago’s water source

Deepwater Horizawhatnow? Less than a year after BP upgraded its Whiting refinery in northwestern Indiana to allow it to handle heavy Canadian tar-sands oil, causing petroleum coke to begin piling up in nearby Chicago, an industrial accident at the refinery has spewed some of that oil into Lake Michigan. The Chicago Tribune reports that it’s not known how long the refinery was leaking or how much oil was spilled. The leak was reported at 4:30 p.m. and plugged by 9 p.m., when an EPA official arrived at the scene. More from the Tribune:
