UPDATE: Husky Energy responds to oil leak timeline
UPDATE: Husky Energy clarified they detected “pressure anomalies” in their pipeline near Maidstone, Sask. the night of Wednesday, July 20, but did not detect a leak that night.
A statement released by Husky Energy said plans were made to fly over the pipeline as soon as there was enough daylight, and the shutdown procedure on the pipeline began Thursday morning as a precaution.
The leak was apparently discovered Thursday morning when a sheen was noticed on the river, at which point an emergency plan was placed into action.
An exact time of the leak has not been pinpointed.
