Keystone XL Pipeline

What Is the Keystone XL Pipeline?

The Keystone XL pipeline was to transport oil from Alberta, Canada, to refineries in the United States. The final phase of the Keystone XL pipeline was to be developed by TC Energy (formerly TransCanada Corporation), which has constructed several other pipelines between Canada and the United States since 2010.

In March 2019, then-President Donald Trump granted a Presidential permit allowing construction of the oil pipeline that was to run through the international border of the United States and Canada. However, on Jan. 20, 2021, President Biden signed an executive order revoking the permit of the Keystone XL pipeline.

Understanding the Keystone XL Pipeline

The Keystone Pipeline was proposed by TransCanada Corp. on Feb. 9, 2005, in a press release, which said, "TransCanada is in the business of connecting energy supplies to markets and we view this opportunity as another way of providing a valuable service to our customers. Converting one of our natural gas pipeline assets for oil transportation is an innovative, cost-competitive way to meet the need for pipeline expansions to accommodate anticipated growth in Canadian crude oil production during the next decade."

The first phase of the pipeline goes from Hardisty, Alberta, to the junction at Steele City, Nebraska, and on to the Wood River Refinery in Roxana, Illinois, and the Patoka Oil Terminal Hub north of Patoka, Illinois. Section two runs from Steele City, Nebraska, south through Kansas to the oil hub and tank farm in Cushing, Oklahoma, then further south to Nederland, Texas, to serve refineries in the Port Arthur, Texas, area. The third phase is the Houston Lateral pipeline, which will transport crude oil from the pipeline in Liberty County, Texas, to refineries and terminals in the Houston area.

In Nov. 2015, President Barack Obama announced his administration would not grant permits for the construction of this pipeline in order to further their commitment to fighting climate change. In his first week at the Oval Office, President Trump signed an executive order clearing the way for the pipeline project. The Republican party had believed that the construction of the pipeline will create more jobs and provide a boost to the economy. On Jan. 20, 2021, President Joe Biden rescinded the construction permit for the Keystone XL pipeline. TC Energy said it was stopping construction earlier the same day.

How the Keystone Pipeline Works

The Keystone system transports diluted bitumen and synthetic crude oil from Alberta through Montana, South Dakota, Nebraska, Kansas, and Oklahoma to refineries located in Texas, Illinois, and Oklahoma. Canada has large reserves of oil locked in oil sands. This oil is considered heavy oil, which requires a different refining process from other types of oil. The production of heavy oil releases particulate matter, such as soot, as well as chemicals such as sulfides, hydrogen cyanide, and sulfur. The finished Keystone XL pipeline is estimated to be able to carry over 800,000 barrels of oil a day.

The Keystone pipeline has been criticized by environmental groups, politicians, and residents of states through which the pipeline passes. These groups have raised concerns about the proposed route's proximity to the Sandhill region of Nebraska and the Ogallala aquifer, the latter of which provides a significant portion of the water used to water crops in the United States. The bitumen carried by the pipeline to the United States will likely result in higher greenhouse gas emissions.

For example, the National Resource Defense Council (NRDC) has filed lawsuits in 2017, 2019, and in July of 2020 to stop the construction of the pipeline. According to the NRDC, tar sands oil is much thicker and more corrosive than typical crude oil and is more prone to leaks and spills through the pipeline. The group stated that the most recent spill in Oct. 2019 resulted in 378,000 gallons of oil spilling in North Dakota.

Proponents of the pipeline say that it will increase the supply of oil to the United States and that oil coming from a friendly neighboring country increases security.
