Exxon-Mobil is mobilizing all of their resources to clean up a rupture in the Pegasus pipeline which has caused thousands of gallons of Canadian bitumen fuel to evacuate 22 homes in what the U.S. Environmental Agency has categorised as a "major spill".
Exxon closed the pipeline on Friday after discovering the leak.
The Pegasus pipeline carries a little over 90,000 barrels of crude oil fuel from Pakota, Illinois to Nederland, Texas.
An Exxon- Mobil spokesman has stated on the record that at the time of the rupture that Pegasus was carrying Canadian Wabasca heavy crude oil which had been diluted with lighter fuel in order to allow it to flow easily through the pipeline system.
The Canadian Energy Pipeline Association known as CEPA has sourced Wabasca Crude as "oil sands".
The Pegasus pipeline was refurbished with "leak -proof technology" in 2009 when it was expanded to specifically transport Canadian oil sands bitumen from the U.S midwest to the Gulf Coast refining hub.
Exxon has confirmed that they are now responding to a spill which they estimate to be 10.000 gallons.
The spill occurred in a subdivision and as DJ goes to press the bitumen has not yet leaked into nearby Lake Conway.
They estimate that they have already cleaned up 4,500 barrels of the spill.
The event is the second spill of Canadian crude oil this week on American soil.
A train shipping Canadian crude derailed in Minnesota on Wednesday spilling 15,000 gallons.
