Afrom Canada through seven states has leaked an unknown amount of crude oil over more than a quarter mile in northeast North Dakota, state environmental regulators said Wednesday. State Environmental Quality Manager Dave Glatt told the Associated Press that regulators were notified late Tuesday night about the leak near Edinburg, in Walsh County. Smooth said that pipeline owner TC Energy shut down the pipeline after the leak was discovered. The cause of the spill is under investigation.
The Calgary, Alberta-based company formerly known as TransCanada, did not immediately respond to AP's phone messages seeking comment Wednesday.
State regulators were at the scene Wednesday afternoon, and they estimated that the discharge area was 1[ads1]500 feet long and 15 feet wide. Smooth said some wetlands were affected, but not any drinking water sources.
The company was still working to contain the spill on Wednesday afternoon.
Crude oil began to flow through the $ 5.2 billion pipeline in 2010. It is part of a system that will also include the proposed $ 8 billion Keystone XL pipeline designed to transport the oil from Western Canada to Gulf terminals Coast.
Earlier Tuesday, the US Department of State held the only meeting for a new environmental review of the long-standing proposal. A federal judge blocked it last year, saying more environmental research was needed.
The original Keystone is designed to transport crude oil across Saskatchewan and Manitoba, and through North Dakota, South Dakota, Nebraska, Kansas and Missouri on the way to refineries in Patoka, Illinois and Cushing, Oklahoma. It has experienced problems with spills in the past, including one in 2011 of more than 14,000 gallons of oil in southeastern North Dakota, near the South Dakota border.
In 2017, theof agricultural land in northeastern South Dakota, in a rural area near the North Dakota border.
Sierra Club, a grassroots environmental group, responded to the leak Wednesday.
"We do not yet know the extent of the damage from this last tar sands, but what we do know is that this is not the first time this pipeline has spilled toxic tar sands, and it will not be the last," Associate Director Catherine Collentine said in a statement. "We've always said it's not a question of whether a pipeline will spill, but when, and once again, TC Energy has made the case for us."
