TC Energy Corp. says it has restarted the southern extension of its Keystone pipeline after fixing a leak Dec. 7 that led to the worst oil spill in the pipeline’s history.
The Calgary-based company says it will operate the pipeline according to plans approved by US regulators, including additional safety measures such as reduced operating pressure.
TC Energy restarted most of the 4,324-kilometer Keystone Pipeline System on Dec. 14, while the 154-kilometer Cushing Extension, running south from Steele City, Nebraska to Cushing, Oklahoma, remained closed after the leak.
The cause of the estimated 14,000 barrel spill, which eclipsed a 2017 spill of 6,600 barrels in North Dakota and a 2019 spill of 4,500 barrels in South Dakota, is still under investigation. .
The company says it has committed to remediating the spill site in Washington County, Kansas, which includes a creek and farmland.
