|Cause: Contract employee observed a sheen (6" x 12") in a tributary leading to Bayou Verdine. Conoco's outfall 004 discharges this to this tributary. Conoco said that they observed no sheen before or immediately after outfall 004. Conoco had an ongoing investigation of the unidentified sheen in the area. The facility placed a boom to contain the sheen from entering Bayou Verdine. The facility inspected all potential sources and found no leaks. Follow up report says that the source of the sheen was not identified but due to subsequent monitoring and testing it is believed to have originated onsite, likely a combination of organic decomposition and runoff from legacy operations.
Notes: Environmental personnel responded. They used absorbent pads for clean up. Engineering alternatives are being evaluated to determine the most effective mitigation to prevent a sheen from this location in the future. The sheen was on a tributary of the Bayou Verdine, and as result of the placement of the booms, did not impact the bayou.
|Cause: On November 16, a fire occurred within the vapor space of the roof on T-71001, the Sour Water Stripper feed tank at Excel Paralubes.
Immediately after the incident, process changes were made to minimize the flow to the tank. The process of removing feed from the tank was completed at 3pm on November 17. Deinventory of the tank contents is nearly complete with an estimated 2 feet of material left in the tank. The process of diluting and removing the remaining material is expected to be completed throughout the next week. Once the tank is completely emptied, a damage assessment will be completed for the tank and any associated equipment. The cause of the incident is under investigation.
Notes: The fire was extinguished quickly and no offsite impact occurred. Based on engineering calculations, it is estimated that the combustion emissions of sulfur dioxide and volatile organic carbons from the first did not exceed the respective reportable quantities.
|Sulfur Dioxide: 268.0 pounds
Hydrogen Sulfide: 7.5 pounds
Ammonia: 2.1 pounds
Volatile Organic Compounds (VOCs): 0.6 pounds
|Cause: A fire occurred on a heat exchanger in the Szorb unit as a result of a leak on the heat exchange system in the Szorb unit. As a result, there was black smoke to atmosphere.
Notes: Feed was pulled from the unit and water monitors were started on surrounding equipment. Investigation is ongoing.
