The Canadian operator of the pipeline that burst in Washington County released its summary of an analysis it commissioned on the cause of the oil spill.
Stress put on the Keystone pipeline during construction, its operator said Friday, contributed significantly to it bursting in north-central Kansas.
TC Energy says an independent review shows the sequence of factors that led to the Keystone’s rupture in December that fouled a creek and spewed oil over cropland and prairie.
The ill-fated segment experienced “inadvertent bending stresses sufficient to initiate a crack” during its construction in 2011, the company said in a press release about the findings.

PO1 William "Chip" Nagel if they had done it right, perhaps things would have tuned out different. Too much pressure on the and in the pipe can cause leaks.

..." Energy initially estimated that 588,000 gallons of crude oil spilled in Kansas. It later lowered the estimate to 543,000 gallons.
However, the U.S. Environmental Protection Agency is sticking to the original figure, which it says matches the agency’s independent calculations.
Last month, the agency said it expects the cleanup will continue for months to come.
TC Energy says it has recovered 98% of the oil, and has cleaned up 90% of Mill Creek’s soiled shoreline.
Mill Creek was initially buried in crude oil nearly a foot deep in some areas. The substance is a tar sands product called dilbit that presents particular environmental challenges when it spills into bodies of water. While most oil tends to float on water, dilbit starts breaking apart into peanut butter-like bitumen that sinks.
Cleanup crews have spent months removing the spilled oil and ultimately isolated and drained about four miles of the creek to help with the process.
The Canadian company has said it expects the cleanup and related work to cost $480 million.
It hasn’t said whether that figure includes the taxpayer money spent by state and federal agencies that responded to the oil spill, part of which the company will be forced to repay."
