Enbridge Energy Partners LP raised its estimate of how much crude oil spilled from a rupture in its Line 6B pipeline near Marshall, Michigan, in July.
The revised spill estimate was 20,082 barrels (843,444 gallons) of crude, the company said in an e-mailed statement. That’s up 3 percent from the initial spill estimate of 19,500 barrels.
The estimate was revised in a supplemental update filed with the Pipeline and Hazardous Materials Safety Administration, a division of the U.S. Transportation Department, said Lorraine Grymala, an Enbridge spokeswoman.
About 18,245 barrels of recovered crude oil is at Enbridge’s Griffith, Indiana, storage terminal, the company said. This doesn’t include oil recovered during the cleanup of the river and creek banks. About 8,033 barrels reached Talmadge Creek, which flows into the Kalamazoo River, Enbridge said.
The 30-inch pipeline, which serves several refineries in the region and can carry 290,000 barrels a day of heavy crude oil from Griffith to Sarnia, Ontario, was shut after the July 26 rupture and reopened about two months later at reduced rates.
