2022 Keystone Pipeline oil spill
The Keystone Pipeline oil spill occurred on December 7, 2022, when a leak in the Keystone Pipeline released 13[1],000 barrels of oil into a creek in Washington County, Kansas.[2] The leak is the largest in the United States since the 2013 North Dakota pipeline spill and the largest in the history of the Keystone Pipeline.[3][4][5] BackgroundThe Keystone Pipeline System spans from the Western Canadian Sedimentary Basin in Alberta to refineries in Texas.[6] The oil pipeline is owned by TC Energy and the Government of Alberta.[7] Pipelines in the Keystone Pipeline System go through stress tests prior to use.[5] Detection and responseAt 9:01 p.m. EDT on December 7, the first indication of a leak on the pipeline was signaled. At 9:08 p.m., TC Energy launched an emergency shutdown of the Keystone Pipeline, following a drop in pressure.[8] The Environmental Protection Agency built an earthen dam to contain the spill.[5] The leak was detected near Washington County, Kansas, and spilled into Mill Creek, a creek that flows directly into the Little Blue River (Kansas/Nebraska).[9] An evacuation order was not ordered.[10][11] Environmental impactThe leak raised concerns from environmentalists due to the transfer of tar sands through the pipeline, which are more toxic than crude oil and can sink in water.[5] Pipeline investigationThe Pipeline and Hazardous Materials Safety Administration began an investigation into the leak.[8] The Environmental Protection Agency dispatched two coordinators, who determined there was no impact to drinking water in the Washington County area.[12] Cause of the spillThe independent analysis of the failure concluded that the failure occurred due to a combination of factors, including bending stress on the pipe and a weld flaw at a pipe to fitting girth weld that was completed at a fabrication facility.[13] Economic impactThe price of crude oil rose 5% following the shutdown of the Keystone Pipeline, before receding. The surge occurred during a selloff of the price of oil, following the 2021–2022 global energy crisis.[8] TC Energy declared a force majeure upon news of the leak.[14] The spill, which leaked into a creek in Washington County, Kansas, cost about $480 million in clean-up efforts.[15] References
