Officials say ‘combination of factors’ led to pipeline leak at Kansas-Nebraska border

LINCOLN, Neb. (KLKN) – TC Energy determined that a “combination of factors” caused the Keystone pipeline spill near the Kansas-Nebraska border in December.

In a statement released Thursday, TC Energy said stress on the pipe and a welding flaw were some of the factors that led to the leak, which was about 20 miles south of Steele City, Nebraska.

“The weld flaw led to a crack that propagated over time as a result of bending stress fatigue, eventually leading to an instantaneous rupture,” the company said.

Officials say TC Energy is working on a remediation plan, which would take a look at other parts of the pipeline with similar conditions.

TC Energy has changed the amount of oil spilled from 14,000 barrels to 12,937 barrels.
