CALGARY, Alberta, Aug 19 (Reuters) - The Alberta Energy
Regulator is investigating a leak on a NuVista Energy NVA.TO
pipeline in northern Alberta which spilled 100 cubic metres,
roughly 629 barrels, of oil and water emulsion, the regulator
said on Wednesday.
The leak on the pipeline, 50 kilometres (31 miles) northeast
of Rainbow Lake, was first identified during an aerial
surveillance flight on Friday, and covered an area approximately
70 by 100 metres. There was no impact on wildlife reported.
Bob Curran, director of public affairs at the Alberta Energy
Regulator, said NuVista shut in the line and a clean up was
under way. AER staff are on site investigating the spill.
NuVista was not immediately available for comment.
Last month an oil sands pipeline owned by CNOOC subsidiary
Nexen Energy 0883.HK leaked 31,500 barrels of bitumen emulsion
in northern Alberta, drawing fierce criticism from
environmentalists.
