Wharf Berth 1: high sulfur light product line
Cause: LDEQ report states, "Motiva reported a leaking high sulfur light product line at the wharf that released approximately six barrels of naptha to the Mississippi River. Leak was caused by external corrosion, and two contributing factors were identified. First, the line was found to be in contact with the insulation of adjacent piping, causing water accumulation between the lines. Additionally, inadequate coating was discovered on the blistered section of piping." A total of 1,748 pounds of chemicals were released to the air.

Followup: No

Notes: RQ. LDEQ report states that "Motiva took the following measures to prevent reoccurrence of this incident: the blistered section of piping will be replaced so it does not contact near-by equipment and the new line will be adequately coated to protect from external corrosion. Motiva has determined that the release was preventable. This incident is an area of concern with regards to LAC 33:III.905 and LAC 33:IX.501.D."
39.0 pounds

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.

Followup: No
