Narrative
On july 27, 2012 at approximately 14:41 local time, adams station line 14 pumps #2 and #3 were shut down due to vibration, with a corresponding decrease in pressure downstream of rio station. Line 14 was shut down and sectionalizing valves were closed. Enbridge co located pipelines lines 6a, 61 and 13 were also shut down as a safety precaution. A release was visually confirmed by enbridge personnel who arrived on site at 15:27 local time. Enbridge has obtained the services of dnv to conduct the metallurgical analysis of the failed pipe section. Once this analysis is complete and supplemented by a root cause failure analysis, a supplemental report will be filed. Although oil did not reach ground or surface water, drinking water is being monitored as a precaution. Contaminated soil will be disposed of at an approved site. Cleanup of the site is close to completion. Approximately 36,120 tons of contaminated soil was removed from the site and disposed of at an approved location.
