Keystone XL

Keystone XL was a proposed expansion of the existing Keystone Pipeline System, designed to transport bitumen from the Athabasca oil sands in Alberta to refineries on the Gulf Coast of the United States. The project, developed by TC Energy, became one of the most contentious energy policy and environmental issues in North America over more than a decade. It faced intense opposition from Indigenous groups, environmentalists, and political leaders, while being supported by the oil industry and various political factions for its promised economic benefits. Its protracted regulatory and legal battles culminated in its cancellation in 2021.

Background and history

The project was first announced by TransCanada Corporation (later TC Energy) in 2008 as a major expansion to the original Keystone Pipeline completed that same year. The need for the expansion stemmed from rapidly increasing production in the Athabasca oil sands and the desire to access lucrative markets and refineries in Texas and Louisiana. The initial application to the United States Department of State was submitted in 2008, triggering a multi-year federal review process under the administration of President Barack Obama. This process required a presidential permit because the pipeline would cross the international border between Canada and the United States at Morgan, Montana. The project's history became intertwined with the broader political debates over climate change, energy independence, and fossil fuel infrastructure during the presidencies of Barack Obama, Donald Trump, and Joe Biden.

Route and technical specifications

The proposed pipeline was to run approximately 1,179 miles from Hardisty, Alberta, connecting to the existing Keystone system at Steele City, Nebraska. Its route traversed the states of Montana, South Dakota, and Nebraska, where it faced significant opposition due to its path across the environmentally sensitive Sandhills region and the Ogallala Aquifer, a critical source of freshwater for the Great Plains. The pipeline was designed with a 36-inch diameter to carry up to 830,000 barrels per day of primarily dilbit (diluted bitumen). Key pumping stations were planned along the route, including facilities near Baker, Montana and Philip, South Dakota. The southern leg from Cushing, Oklahoma to the Gulf Coast, sometimes conflated with the project, was constructed separately as the Gulf Coast Pipeline Project.

Environmental and economic impacts

Proponents, including the Government of Alberta, American Petroleum Institute, and several Chamber of Commerce groups, argued the project would enhance energy security, create thousands of construction jobs, and generate significant tax revenue for local counties and states. Opponents, led by coalitions like the Sierra Club, Natural Resources Defense Council, and the Indigenous Environmental Network, raised major concerns. These included risks of spills contaminating the Ogallala Aquifer, increased greenhouse gas emissions from expanded oil sands development, and the violation of treaty rights of Indigenous nations such as the Rosebud Sioux Tribe and Fort Belknap Indian Community. The Environmental Protection Agency and the U.S. Geological Survey often provided analysis that fueled the debate over potential ecological damage.

Political and legal developments

The project's permit application entered a prolonged period of federal review. In 2015, President Barack Obama denied the permit, citing concerns that it would undermine U.S. leadership on climate change. This decision was reversed in 2017 by an executive order from President Donald Trump, who granted a new presidential permit. This action triggered numerous lawsuits from states like Montana and environmental groups, leading to injunctions that halted construction. Legal challenges often centered on compliance with the National Environmental Policy Act and the Endangered Species Act, particularly regarding the American burying beetle and the whooping crane. The Supreme Court of the United States intervened at times, such as in 2020, to lift a key injunction.

Cancellation and aftermath

Following the 2020 election, President Joe Biden revoked the project's permit via executive order on his first day in office in January 2021. TC Energy officially abandoned the project in June 2021 after the Government of Alberta terminated its financial support. The cancellation had immediate repercussions, affecting companies like Kiewit Corporation that were contracted for construction and leading to diplomatic strains between the United States and Canada. The debate over the pipeline continues to influence discussions on energy infrastructure, climate policy, and Indigenous rights, with the existing Keystone Pipeline system remaining in operation. The outcome is seen as a landmark victory for the climate movement and a case study in the power of sustained environmental activism.
