Companies TC Energy Corp FollowDec 23 (Reuters) - TC Energy Corp (TRP.TO) on Friday said that a U.S. regulator had approved a restart plan for an idled segment of its Keystone oil pipeline to Cushing, Oklahoma, and it looked to restore service after several days of testing and inspections. The 622,000-barrel-per-day (bpd) pipeline was shut on Dec. 7 after it spilled 14,000 barrels of oil in rural Kansas, the biggest U.S. spill in nine years. The shutdown reduced the flow of Canadian crude to Gulf refineries, but it has had little impact on Canadian oil prices, partly because of ample storage in Alberta. Pipeline and Hazardous Materials Safety Administration (PHMSA) approved the restart plan, TC said. Frigid weather at the spill site may slow work, TC said.
