Injunction against Keystone XL quashed, but hurdles remain for embattled pipeline

An injunction against the Keystone XL pipeline has been quashed in the U.S., but challenges to the project remain.

A Montana judge ruled that the old permit for the pipeline, which was replaced by the Trump administration, is no longer valid. Therefore, the injunction associated with it no longer applies.

"So as of now there is no injunction that's preventing Keystone XLfrom beginning construction," said James Coleman, a law professor atSouthern Methodist University in Dallas, Texas.

"And this was the first part of the plan that the Trump administration put into practice when at the start of April they revoked the old permit and permanent process for cross-border pipelines and established a new one and gave Keystone a permit under that new one."

Construction held up by court

A Montana court will now have to rule on whether the new permit, which givesDonald Trump the authority to approve the project,is itself valid.

Previously, the courts had ruled approval of the pipeline did not take into consideration new developments and an environmental review was incomplete.

Trump then introduced his permit, which bypassed that process and place authority in his office.

Groups opposed to the pipeline had been fighting in court based on the previous permit.

Environmental opposition

Some, however, notethe fight isn't over.

"The Keystone XL pipeline is a disaster waiting to happen and we will not stop fighting it, or President Trump's extraordinary misuse of executive power to disregard the courts and environmental laws,"saidJackie Prange, senior attorney with the Natural Resources Defense Council in a statement.

"We will explore all available legal avenues to stop this dirty tar sands oil pipeline from ever being built and endangering our communities and climate."

That determination was echoed byJared Margolis, a senior attorney at the Center for Biological Diversity, in the same statement.

"The Trump administration thinks it's getting away with approving this dangerous project without adequate environmental review, but we'll keep fighting Keystone XL to protect the people and wildlife in its path and prevent further harm to our climate," he said.

Lost time, lost money

TC Energy, formerly TransCanada, has already said the delays mean it won't have shovels in the ground this year.

In court documents, the company has saiddelays beyond March 15 could set the project back a whole year from its intended completion date in 2021, costing the company hundreds of millions of dollars in lost earnings.

The Keystone XL pipeline, first announced in 2005, would carry 830,000 barrels of crude a day fromHardisty, Alta.,to Nebraska. The pipeline would then connect with the original Keystone that runs to refineries in Texas.

TheObamaadministration denied KeystoneXL'spermits, but Trump breathed life back into the project after giving it hispresidential thumbs-up.
