EDMONTON -- Inter Pipeline Ltd. said Monday that its Cold Lake pipeline was the source of an oil leak discovered late last week in an industrial area east of Edmonton.
The company said it learned of a potential leak near its Strathcona Terminal at around noon Friday, but it wasn't until Monday morning that it confirmed the oil came from its line.
The Alberta Energy Regulator said several operators had shut in their lines on the right of way when the leak was discovered because the source was unclear.
Inter Pipeline (IPL.TO) said the leak was contained on Friday and it continues to work on cleaning up the spill as lead responder to the incident.
The Alberta Energy Regulator, which is overseeing the response, said it still doesn't know how much oil spilled.
AER spokeswoman Monica Hermary said the crude spilled into an unnamed creek that flows into the North Saskatchewan River, but the leak was contained before it reached the river.
The spill killed one bird, while a beaver and a muskrat were taken in for treatment, said Hermary.
Imperial Oil was first to discover the Inter Pipeline leak Friday, and said Sunday that it was responding to a separate leak at its Cold Lake operation.
The company said it estimates about 900,000 litres of produced water spilled from a storage lagoon at its steam-based oilsands operation in northeast Alberta.
Produced water is a byproduct of oil production, with the water pumped to the surface along with the bitumen before being treated and reused in operations.
