Viking Station Release
At approximately 3:45 p.m. CDT on Tuesday, April 23, Enbridge personnel at our Viking, Minn., Station observed a small amount of oil on the ground. The leak is on small diameter station piping associated with Line 2. The control center was immediately notified and Line 2 was shut down and isolated as a precaution within minutes. Viking Station staff responded and completed repairs and Line 2 was safely restarted at approximately 9 p.m. CDT on April 23.
The released product – a light sour blend – was found in a small area within the Viking Station perimeter where protective barriers, including berms and graded soil, are in place to protect the surrounding environment. The release was fully contained within the existing containment berm. Berms are built according to regulatory requirements and Enbridge specifications using clay or compacted soil and grading to allow drainage to a designated area.
The cause of the leak is under investigation.
