CALGARY, Alberta (Reuters) - Plains All American Pipeline LP said on Monday it is repairing the Rainbow pipeline in northern Alberta after the 187,000 barrel per day line ruptured last week.
Roy Lamoreaux, a spokesman for the company, said there was still no estimate on how much oil spilled out before the line was shut down on Friday and Plains cannot yet say when repairs will be completed.
"We have not put an estimate on the volume," he said.
Regulators say the spill was of significant size, with hundreds of barrels of oil leaking out. Plains said the spill has been contained to an area 800 by 50 meters (2,625 by 164 feet).
The Rainbow pipeline runs from Zama in northwest Alberta 770 km (480 miles) south to Edmonton. The leak occurred 100 km northeast of Peace River, Alberta.
Lamoreaux said the pipeline was open south of the damaged section. That portion of the pipe, from the Nipisi terminal to Edmonton, typically delivers about half the line's capacity.
The April 29 incident was the second leak for an Alberta pipeline in a week. Kinder Morgan Energy Partners's 300,000 bpd Trans Mountain oil pipeline was shut for five days beginning on April 22 after a small leak was spotted on the line's right-of-way 150 km west of Edmonton.
