Enbridge’s 6A pipeline has been shutdown following a leak this afternoon in the Chicago suburb of Romeoville. Line 6A carries crude oil from Superior, Wisconsin to Griffith, Indiana. The 6B pipeline which runs from Griffith, Indiana to Sarnia, Ontario has been shut down since a July 26th rupture on the line spilled around a million gallons of Cold Lake crude into the Kalamazoo River system.
The Toronto Globe and Mail reports:
Line 6A is a major pipe that feeds both Line 6B, the pipe that was closed after the Michigan spill, and another line to Cushing, Okla., a major crude hub. The route to Cushing had taken on new importance as an alternative for Canadian oil shippers once Line 6B was closed; if the Line 6A closing is long-lasting, it could cause a substantial amount of additional disruption.
The second leak comes on the same day Enbridge chief executive officer Pat Daniel met with U.S. Speaker of the House Nancy Pelosi in Ottawa, where high-powered oil executives discussed the improving environmental record of the oil sands.
CBS News Chicago reports that crews from Enbridge, the Romeoville Fire Department, Romeoville Police Department, U.S. Coast Guard, Illinois Environmental Protection Agency, Illinois Department of Natural Resources and Will County Forest Preserve are assisting in cleanup efforts.
It’s not yet clear what caused the spill of how much oil was released.
Chicagobreakingnews.com reports that officials with the U.S. Environmental Protection Agency are concerned that the spill is occurring near a storm drain.
