Narrative
On 8/13/2016 at 4:10 am a third party operator from exxon facilities notified enterprise control center of a possible leak on the wilprise assets located near the underground storage facilities in sorrento, louisiana. Enterprise dispatched local area technician to the site and found a 1/2 inch relief valve on a filter separator relieving to atmosphere. The technician was able to block a manual valve under the relieve valve to stop the ongoing release. Investigation of the incident indicates that the relief valve opened at the intended set point and would not reset once pressure fell below set point. Debris was found in the seat area of the relief valve which would not allow the valve to reset. A new relief has been installed with the pressure set point at or below mop of the pipeline. The filter separator has been returned to service.
