TransCanada says its Keystone pipeline is likely the source of an oil leak near St. Louis.

Spokesman Terry Cunha in a Friday statement said crews continue to excavate the St. Charles County area where the leak was discovered Wednesday. He said TransCanada's preliminary investigation points to Keystone.

A spokesman for Enbridge Inc. said it's "highly confident" that its nearby Platte pipeline wasn't the source.

The leak prompted closures of sections of both the Keystone and Platte pipelines.

Enbridge spokesman Devin Hotzel said Friday that the company expects its pipeline will be operating normally by Saturday.

Cunha says there's no estimated time for the Keystone pipeline to return to service.

The Missouri Department of Natural Resources has estimated that about 43 barrels, or 1,800 gallons (6,814 liters), of oil leaked. It said the oil did not get into any waterways.
