Keystone's existing pipeline spills far more than predicted to regulators- TransCanada Corp’s (TRP.TO) existing Keystone pipeline has leaked substantially more oil, and more often, in the United States than indicated in risk assessments the company provided to regulators before the project began operating in 2010, according to documents reviewed by Reuters.

The Canadian company is now seeking to expand the pipeline system linking Alberta’s oil fields to U.S. refineries with its proposed Keystone XL project, which has U.S. President Donald Trump’s backing.

The existing 2,147-mile (3,455 km) Keystone system from Hardisty, Alberta, to the Texas coast has had three significant leaks in the United States since it began operating in 2010, including a 5,000-barrel spill this month in rural South Dakota, and two others, each about 400 barrels, in South Dakota in 2016 and North Dakota in 2011.
