A 200,000 barrel per day oil pipeline belonging to a unit of Plains
All American Pipeline LP ruptured on Friday, spilling hundreds of
barrels of oil, regulators said.

Plains’ Rainbow pipeline, which
runs from Zama in northwest Alberta 770 kilometres south to Edmonton,
sprung a leak at 7: 30 a.m. local time.

“It’s not a small leak,”
said Davis Sheremata, a spokesman for Alberta’s Energy Resources
Conservation Board, which regulates pipelines in the province.

“It’s a significant leak, in the hundreds of barrels.”

The leak occurred 100 km northeast of Peace River, the regulator said.

The
ERCB said the line was shut down and the company and authorities were
working on cleanup efforts. The regulator said the spill was 300 metres
from flowing water and seven kilometres from the nearest residence.

It’s
the second leak from 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.
