Keystone Pipeline Leak In S Dakota About Double Previous Estimate: Paper

"The Keystone crude oil pipeline leak in November in rural South Dakota was nearly double the original estimate, making it one of the largest U.S. inland spills since 2010, a newspaper report on Saturday said.

Robynn Tysver, a spokeswoman for Calgary-based TransCanada Corp, which owns the pipeline, told the Aberdeen American News some 9,700 barrels of oil leaked in the Nov. 16 spill, the South Dakota paper reported. The original estimate was 5,000 barrels.

The spill gave further ammunition to environmental groups and other U.S. opponents of another pipeline the company has proposed, the long-delayed Keystone XL."
