2011-04-28		Flare: EPN 3-84
Cause: A leak occurred at HIC-84, along the downstream block valves, allowing nitrogen to enter the column causing a rapid pressure increase. The distilling unit upper crude column became overpressured, and PCV-195 opened the flare to relieve pressure in the column. EPN 3-84 Flare at Shell was used because the Motiva flare was upset and the pilot light was out. Original upset occurred at Motiva DU-5 Crude Unit with a notrogen leak into the Upper Crude Column.

Followup: No

Notes: The Shell report for the motiva release was dated May 5th, 2010 instead of 2011.
