|DU-5 Naptha Stripper Reboiler [E-1004]||Cause: A leak in the weld of a pipping elbow of the DU-5 Naptha Stripper Reboiler caused by internal corrosion on the reboiler.|
Notes: RQ. Reportable quantities were exceeded for 8 chemicals including Ethane, Methane, Toulene, and n-Hexane. Refinery report states that "immediately following discovery of the leak, the site's emergency response team was activated and the naphtha stripper was blocked in and depressurized."
|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.|
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."
