Leak in the Keystone pipeline spilled 9,000 barrels of oil in North Dakota

More than 9,000 barrels of oil are estimated to have spilled from a leak in the Keystone Pipeline in northeastern North Dakota, the company said. It is the second significant two-year spill in the pipeline that runs from Canada's tar sands region and through seven US states.

Crews closed the pipeline after the leak was discovered Tuesday night, Karl Rockeman, North Dakota's director of water quality, told the Associated Press.

TC Energy, formerly known as TransCanada and who runs the pipeline, said Thursday that an estimated 9,120 barrels of oil, enough to fill half of an Olympic-size pool, were dumped.

Using the first estimate, it amounts to around 383,000 gallons. The company says it will not know the exact amount until the oil recovery is complete.

The leak occurred near the company's facility near Edinburg, a community of about 200 people in Wash County about 60 miles northwest of Grand Forks, TC Energy said. The North Dakota Department of Environmental Quality said the leak was 3 miles northwest of Edinburg.

"Our emergency response team contained the affected area, and oil has not migrated beyond the immediately affected area," TC Energy said in a previous update.

It said that crews remain focused on oil recovery and will then perform pipeline repairs. Crews use vacuum cars and tractors to recover the oil, it says.

Rockeman told the AP that some wetlands were affected, but not any drinking water sources.

In November 201[ads1]7, more than 200,000 gallons of oil – around 4,700 barrels – leaked in South Dakota The leak occurred in a sparsely populated area of ​​Marshall County, near Amherst in the northeastern state.

The $ 5.2 billion pipeline is designed to transport crude oil across Saskatchewan and Manitoba, and through Nort h Dakota, South Dakota, Nebraska, Kansas and Missouri to refineries in Patoka, Illinois and Cushing, Oklahoma, and the can handle 23 million liters daily.

TC Energy is also seeking to build the Keystone XL pipeline that would begin in Hardisty, Alberta and move to Steele City, Nebraska.

Because the pipeline would cross an international border, the US Department of State is gathering public comments on its revised environmental impact statement for the pipeline, NPR reported Thursday. An entry on October 4 in the federal registry says that the public comment period is expected to end November 18.

The Keystone XL proposal was rejected by the Obama administration in 2015, but approved by the Trump administration in 2017. [19659002] TC Energy says the XL pipeline will create jobs under construction as well as other benefits.

It says on their website that they want to start construction in 2010, and that construction will take around two years.

Environmental groups and others have opposed the project. The Sierra Club said in a statement Wednesday that the discharge from the Keystone 1 pipeline is one of a dozen spills in its first year of operation.

"We do not yet know the extent of the damage from this last tar sands discharge. But what we do know is that this is not the first time this pipeline has spilled toxic tar sand, and it will not be the last," says Sierra Club Beyond Dirty Fuels , Director Catherine Collentine.

"We have always said it is not a question of whether a pipeline will spill, but when, and once again, TC Energy has made the case for us," Collentine said.

Greenpeace USA tweeted about the spill: "Brought to you by the company that wants to build the much larger # KXL pipeline and have it cut straight through the Midwest," citing Keystone KL.

Sen. Bernie Sanders, I-Vermont, who is running for Democratic presidential nomination, in a tweet Thursday accused President Donald Trump of ignoring science and putting profits ahead of the environment.

"As president, I want to shut down the Keystone Pipeline that should never have been built in the first place," Sanders said.
