Erwin Seba/REUTERSCompanies TC Energy Corp FollowDec 21 (Reuters) - The U.S. pipeline regulator launched a review this year of its special permits that waive certain operating requirements for pipelines, following a government report into spills on TC Energy's Keystone oil pipeline, a source familiar with the matter said.
The most recent major spill occurred this month in rural Kansas along Keystone, the only U.S. oil pipeline with a special permit to operate at higher pressure.
PHMSA commissioned Oak Ridge National Laboratory, a Department of Energy research institution, to review special permits following a 2021 report on Keystone accidents, the source said.
The latest Keystone spill raises doubts about whether PHMSA adequately assesses risk in granting special permits, said Don Deaver, a pipeline consultant.
