South Bow agrees to pay $26.9M in civil penalties and to spend about $40M on safety upgrades after a December 2022 Keystone Pipeline rupture that released nearly 13,000 barrels of heavy crude into a Washington County creek.The Environmental Protection Agency, the DOJ and Kansas say engineering failures — an overstressed bend and improperly compacted soil under the pipe — caused the largest onshore crude pipeline spill in the US in nine years and damaged land and water while harming more than 2,700 animals, including endangered long-eared bats.South Bow denies legal liability but completed cleanup earlier this year; the proposed settlement requires judicial approval after a public comment period and adds to scrutiny of pipeline oversight following President
Donald Trump’s approval of a second Canada-to-Wyoming pipeline.
