===Previous dilbit spill remediation difficulties===
One of the major concerns over [[dilbit]] is the difficulty in cleaning it up.<ref>[http://www.loe.org/shows/segments.html?programID=12-P13-00027&segmentID=1 "Kalamazoo River Spill Yields Record Fine"], ''[[Living on Earth]]'', July 6, 2012.

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 oil-contaminated sediment and debris from the Kalamazoo River system. However, oil was still being found in affected waters in October 2012.<ref>[http://www.epa.gov/enbridgespill/ "More Work Needed to Clean up Enbridge Oil Spill in Kalamazoo River"], US EPA, October 3, 2012.</ref>
