Pipeline transport Department does not include a quantitative analysis because it assumed that most benzene will volatilize. One of the major concerns about dilbit is the difficulty in cleaning it up. Enbridge's Line 6B, a 30-inch crude oil pipeline, ruptured in Marshall, Michigan on July 25, 2010, mentioned above, spilled at least 843,000 gallons of dilbit. After detection of the leak, booms and vacuum trucks were deployed. Heavy rains caused the river to overtop existing dams, and carried dilbit 30 miles downstream before the spill was contained. Remediation work collected over 1.1 million gallons of oil and almost 200,000 cubic yards of
