CALGARY, Alberta, Jan 4 (Reuters) - Enbridge Inc shut down a crude oil pipeline for approximately three hours on Monday morning, a company spokesman said, after protesters opposed to oil sands development partially restricted flow on the pipeline on Sunday night by tampering with a valve station.
Spokesman Graham White said the Line 7 crude oil pipeline, which carries around 150,000 barrels per day of crude from Sarnia, Ontario, to Westover, Ontario, was shut down as a precaution so maintenance workers could inspect the valve station.
Line 7 was restarted on Monday and White said there was no impact on deliveries.
It is the second time in a month that Enbridge has been forced to shut down a pipeline as a result of protests by environmental groups. (Reporting by Nia Williams)
