The reason why that spill was particularly disastrous was because of the type of oil involved: Canadian tar sands crude oil, which Enbridge frequently transports. When it spills, tar sands oil does not float on top of water like conventional crude. Instead, it gradually sinks to the bottom, making normal cleanup techniques and equipment of little use. Tar sands oil is too thick to transport in its original state, so it also needs chemicals like benzene to liquefy it for pipelines. That means that when tar sands spill, those chemicals evaporate into the air. thinkprogress.org/climate/2014/12/18/3605276/enbridge-oil-spill-canada/
