U.S. EPA says Keystone pipeline rupture spilled diluted bitumen, complicating cleanup

Emergency crews work to clean up a leak from the Keystone pipeline, in Washington County, Kan., on Dec. 9.DRONE BASE/Reuters

The oil spilled from TC Energy Corp’s ruptured Keystone pipeline was diluted bitumen, the U.S. Environmental Protection Agency (EPA) said on Thursday, adding complications to the cleanup.

The 622,000 barrels per day (bpd) pipeline was shut since last week after it spilled 14,000 barrels of oil in rural Kansas, including into a creek.

The parts of the pipeline carrying oil from Alberta, Canada, to refineries in Illinois opened on Wednesday, leaving the ruptured part that extends from south of Steele City, Nebraska to a storage hub in Cushing, Oklahoma closed.

Bitumen from Canada’s oil sands is a dense, thick form of oil that shippers dilute with lighter oils so it can move through pipelines. The resulting product is called dilbit for short.

A 2016 National Academy of Sciences study for the U.S. Department of Transportation examined whether transporting dilbit carries different environmental risks than other oils, following a 2010 spill in Michigan.

The report said that when diluted bitumen spills, a thick, dense material forms as a residue after exposure to the environment. The residue tends to stick to surfaces, sometimes sinking to the bottom of a water body where it is difficult to recover.

“For this reason, spills of diluted bitumen pose particular challenges when they reach water bodies,” the report said.

Crews are using equipment to skim water off the surface of Mill Creek in Kansas and to vacuum oil into trucks. Colder temperatures may hamper the cleanup, the EPA said.

The Sierra Club, an environmental advocacy group, questioned why parts of the pipeline reopened before TC Energy had identified the leak’s cause.

“How can we be assured that other segments of the pipeline aren’t equally prone to failure and causing disaster?” said Zack Pistoria, Sierra’s lobbyist in Kansas.

More than 400 people are involved in the cleanup including personnel from EPA, U.S. Pipeline and Hazardous Materials Safety Administration, state and local agencies, TC Energy and TC Energy contractors, the agency said.

The response team has so far recovered 5,567 barrels of oil-water mixture from Mill Creek.

The EPA said four dead mammals have been recovered, along with 71 fish.
