What impact the spillage of 19,500 barrels of crude oil into southwestern Michigan waterways will have on the Enbridge Energy Partners facility in Griffith where the pipeline originates isn't known.

The 8-million gallons of crude oil that flows along that pipeline daily from Griffith to Sarnia, Ontario in Canada was stopped by Enbridge officials Monday.

Patrick D. Daniel, president and CEO of Calgary, Alberta-based Enbridge Inc., said during a Wednesday press conference the company doesn't know when the oil flow will be resumed. One alternative is to send the crude oil from Griffith through Toledo, Ohio. However, Daniel said that hasn't been initiated yet.

Also unknown at this time is whether employees from the Griffith facility are part of hundreds of Enbridge employees, contractors and federal officials working on the containment and clean-up efforts.

Daniel said Enbridge is doubling the size of its work force to contain and cleanup the spill, and is adding 31,000 more containment booms to the 14,000 booms already in place to keep the crude oil from spreading.

Michigan Gov. Jennifer Granholm toured the area by helicopter Tuesday night and said she wasn't satisfied with the response to the spill. The leak in the 30-inch pipeline, which was built in 1969, was detected Monday.

However, calls by residents to 911 and a Michigan utility company reporting fumes began Sunday evening, emergency records indicate. Granholm declared a state of disaster in Calhoun County and potentially affected areas along the river.

Ralph Dollhopf of the EPA said the federal government holds Enbridge responsible for the containment and cleanup.
