TransCanada, one of the largest companies involved in tar sands exploration, has proposed a 1,661 mile, 36-inch extension of the newly built Keystone Pipeline from Alberta, Canada to Texas in the United States. This would expand the capacity for refining oil produced from the Alberta tar sands by approximately one million barrels per day.
Greenhouse gas emissions from the tar sands are higher than those emitted from conventional oil due to the energy intensive extraction process. The extraction process is also highly costly in terms of natural gas and water usage, resulting in a legacy of huge tailing ponds of contaminated water. In addition the development of the tar sands is resulting in an attack on the lifestyle of indigenous populations in the area.
The Keystone XL extension is planned to traverse six U.S. states and cross major rivers, including the Missouri River, Yellowstone, and Red Rivers, as well as key sources of drinking and agricultural water, such as the Ogallala Aquifer, which supplies two million Americans. Operation of TransCanada's Keystone I pipeline has already shown that spills are likely prompting a corrective action order from the Department of Transportation.
