The U.S. pipeline regulator said on Tuesday it would require TC Energy to reduce operating pressure on more than 1,000 additional miles (1,609 kilometers) of its Keystone pipeline that spilled about 13,000 barrels of oil in rural Kansas in December.
In addition, operating pressure on the rest of the pipeline extension from Steele City, Nebraska to the Cushing storage hub and on the entire 1,025-mile main line from the Canadian border to refineries in Illinois, must not exceed 72% of the specified minimum yield strength .
This effectively amounts to a suspension of the special permit that PHMSA issued to TC Energy in 2007, allowing the pipeline to operate at a stress level of 80% of its SMYS, and the order requires TC Energy to review the pressure restriction monthly. The pressure reductions will lower crude flow rates on the entire Keystone system, which could affect price differentials between U.S. and Canadian crude, Credit Suisse analyst Andrew Kuske said in a note.
TC Energy will also be required to submit an independently conducted root cause failure analysis, followed by a remedial work plan and proposed measures to mitigate consequences of a failure, according to the order.The PHMSA said it issued the order without a hearing considering various factors that include "the increasing severity of spills in recent years" and "the possibility of future failures," while its investigation into the cause of the December spill was ongoing.
It revised the discharge volume to 12,937 barrels by measuring the crude injected to refill the pipeline during its restart, while the U.S. Environmental Protection Agency said it continued to work from its independent initial estimate of 14,000 barrels.Our Standards:
