Keystone Pipeline has history of spills, warnings and fines. This Kansas spill is the largest yet...

The Keystone pipeline failed again last week, dumping 14,000 barrels — or 588,000 gallons — of oil in northern Kansas. In the decade since it began operations, the crude oil pipeline’s Canadian owner, TC Energy, has paid just over $300,000 fines for the damages it's caused.
Federal regulators have issued warnings repeatedly over the life of the Keystone pipeline that operators aren’t doing enough to prevent corrosion and don’t follow proper construction procedures.

But despite a history of warnings and large spills, the Keystone pipeline failed again last week, dumping 14,000 barrels — or 588,000 gallons — of oil in northern Kansas. It’s the largest spill since the pipeline began operations about a decade ago.
