OPINION: Opponents of the now-scuttled Keystone XL pipeline project are saying, “I told you so,” after TC Energy’s existing Keystone Pipeline System spilled around 14,000 barrels of oil last week, with some pouring into a Kansas creek. They have a point.

The causes of the latest spill were still being investigated this week, but it was possible to trace a pattern emerging from two other significant incidents on the same pipeline system, resulting in the spilling of 6592 barrels of crude in South Dakota in 2017 and another 4515 barrels in North Dakota in 2019.
