Keystone pipeline shut after 14,000-barrel oil spill in Kansas

/ 07:48 AM December 09, 2022

Canada’s TC Energy shut its Keystone pipeline in the United States after more than 14,000 barrels of crude oil spilled into a creek in Kansas, making it one of the largest crude spills in the United States in nearly a decade.

The cause of the leak, which occurred in Kansas about 20 miles south of a key junction in Steele City, Nebraska, is unknown. It is the third spill of several thousand barrels of crude on the pipeline since it first opened in 2010.

The 622,000 barrel-per-day Keystone line is a critical artery shipping heavy Canadian crude from Alberta to refiners in the U.S. Midwest and the Gulf Coast. It is unclear how long the closure will last.

There have been no effects on drinking water wells or the public, the U.S Environmental Protection Agency said in a statement, though surface water of Mill Creek was affected. It sent two coordinators to the site to oversee TC Energy’s response and evaluate the cause of the spill.

Keystone shut the line at about 8 p.m. CT Wednesday (0200 GMT Thursday) after alarms went off and system pressure dropped, TC said in a release. It said booms were being used to contain the spill.

“The system remains shut down as our crews actively respond and work to contain and recover the oil,” the release said.

According to U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) data, this would be the largest crude oil leak since a Tesoro pipeline leaked more than 20,000 barrels of oil in North Dakota in October 2013.

The PHMSA is also investigating the leak, which occurred near Washington, Kansas, a town of about 1,000 people.

There have been seven Keystone spills since it became operational in June 2010, according to PHMSA data. The largest were in December 2017, when more than 6,600 barrels spilled in South Dakota, and in November 2019, when more than 4,500 barrels spilled in North Dakota, according to PHMSA figures.

TC declared force majeure over the outage, according to a source with direct knowledge, which refers to unexpected external circumstances that prevent a party to a contract from meeting its obligations. TC did not respond to a request for comment.

Two Keystone shippers said TC had not yet notified them how long the pipeline may be shut.

Keystone’s shutdown will hamper deliveries of Canadian crude both to the U.S. storage hub in Cushing, Oklahoma and to the Gulf, where it is processed by refiners or exported.

The shutdown is expected to increase the discount on Western Canada Select (WCS) heavy oil from Alberta to U.S. crude, which was already high due to lackluster demand for heavy, sour Canadian oil.

WCS for December delivery traded at $33.50 a barrel below WTI, a bigger discount than Wednesday’s settle of $27.50 a barrel below the benchmark, according to one broker.

“It’s really a worst-case scenario if this outage is long-lasting,” said Rory Johnston, founder of energy newsletter Commodity Context, noting that if the price falls further, shippers may opt to move crude by rail.

The Hardisty, Alberta, hub has sufficient storage space until the pipeline is back online, said BMO analyst Randy Ollenberger.

Steele City is roughly the junction where Keystone splits, with one segment moving crude to Illinois refineries and the other carrying oil south to Oklahoma and the Gulf Coast.

If the spill is located south of the junction, TC may be able to quickly restart the segment to Illinois, RBC analyst Robert Kwan said in a note.

Past shutdowns have generally lasted about two weeks, but this could last longer as it involves a water body, Kwan said.

On Nov. 15, TC announced it would curtail volumes on the pipeline due to some severe weather-related incidents, without specifying the size or duration of the curbs.

TC shares ended down 0.1 percent in Toronto.
