REUTERS/Drone Base/File PhotoDec 14 (Reuters) - One week after Canada's Keystone pipeline spilled more than 14,000 barrels of oil in rural Kansas in the United States, the cause is still unknown, according to regulators.
Oil sprayed nearby pastures and leaked into Mill Creek before being shut by operator TC Energy.
The timeline for the full restart of the pipeline remained uncertain, and neither a root cause failure analysis nor a restart plan had been submitted, the U.S.
The spill occurred in Washington County, Kansas, about 20 miles (32 km) south of a junction in Steele City, Nebraska, where Keystone splits into two.
"We don't have a confirmation of a timeline and anticipate an update on restart today," TC said in an email.
