It is estimated that more than 9,000 barrels of oil leaked from a leak in the Keystone pipeline in northeastern North Dakota. It is the second major leak in two years in the pipeline that runs from Canada's tar sands region through seven US states.
The crew shut down the pipeline after the leak was discovered Tuesday night. Karl Rockeman, Head of Water Quality, North Dakota. said the Associated Press. The oil spill affected a wetland.
TC Energy, formerly TransCanada, which operates the pipeline, announced Thursday that it has estimated that 9,120 barrels of oil have been released in the United States, enough to fill half of an Olympic swimming pool.
According to this initial estimate, that's about 383,000 gallons. The company claims to know the exact amount only when the oil extraction is completed.
The leak occurred near the company in Edinburgh, a community of about 200 residents in Wash County, about 60 miles northwest of Grand Forks, TC Energy said. The North Dakota Department of the Environment stated that the leak was located 3 miles northwest of Edinburgh.
"Our emergency team included the affected area and oil did not migrate beyond the immediate area," TC Energy said in an earlier update.
It was said that the crews would continue to focus on oil production and then make repairs to the pipeline. The crews use vacuum trucks and backhoe loaders to recover the oil.

The $ 5.2 billion pipeline will transport oil through Saskatchewan and Manitoba and through Nort Dakota, South Dakota, Nebraska, Kansas and Missouri en route to refineries in Patoka, Illinois and Cushing, Oklahoma can hold 23 million gallons daily.
TC Energy is also seeking to build the Keystone XL pipeline, starting in Hardisty, Alberta, and going to Steele City, Nebraska.
With the pipeline crossing an international border, the US State Department is gathering public comments on its revised environmental impact statement for the pipeline, NPR reported Thursday. According to an entry in the Federal Register of 4 October, the public comment period is expected to end on 18 November.
The proposal for Keystone XL was rejected by the Obama administration in 2015, but endorsed by the Trump government in 2017.
] TC Energy says the XL pipeline creates jobs during construction and other benefits.
His website states that the construction should start in 2010 and that the construction will take about two years.
Environmental groups and others have rejected the project. The Sierra Club said in a statement on Wednesday that the release from the Keystone 1 pipeline is one of a dozen releases in its first year of operation.
"We still do not know to what extent this recent tar sands release is causing damage, but we know this is not the first time this pipeline has spilled toxic tar sands, and it will not be the last "said Catherine Collentine, associate director of Sierra Club Beyond Dirty Fuels.
"We've always said that it's not about whether a pipeline ran out, but when and once again TC Energy came in for us," Collentine told them about the company that owns the much larger # KXL Pipeline construction and slicing through the Midwest ", referring to the Keystone KL.
