Nexen Pipeline Spill Troubling For Energy, Environment Ministers

FORT MCMURRAY, Alta. — Alberta's energy and environment ministers say they're troubled by a huge pipeline spill that was discovered in the oilsands region last week.

Marg McCuaig-Boyd and Shannon Phillips toured the cleanup site 35 kilometres southeast of Fort McMurray, along with a representative from a nearby aboriginal community.

Both ministers say they have confidence in the investigation underway by the Alberta Energy Regulator, an arms-length watchdog.

The ruptured year-old pipeline at Nexen Energy's Long Lake oilsands site spilled about five million litres of bitumen, sand and produced water over a 16,000-square metre area.

Phillips says despite the event, pipelines are still the safest way to transport petroleum products.

Byron Bates, a councillor with the Fort McMurray 468 First Nation, says some members of his community were so disturbed by the spill they couldn't watch news coverage of it.
