|Tank D6360||Cause: The two nitrogen regulators on the fixed roof of asphalt tank D6360 were bad, keeping the tank pressurized even during offloading. This caused the tank to vent steamy emissions from multiple vents on the fixed roof.|
Notes: Air monitoring at the site and around the perimiter was consistently conducted during the incident, revealing only low levels of VOCs on the levee and paying particular attention to Polynuclear Aromatic Hydrocarbon. The tank was offloaded into three barges, and the tank was cooled to reduce vapors. Upon inspection, the vents appeared to be working properly, and the nitrogen regulator was later found to be faulty. The crew reduced the nitrogen input, relieved the pressure of the tank, and closed the vents to stop emissions. An all-clear was then called, and the nitrogen regulators were to be repaired. No road closures, fires, injuries, or fatalities resulted from this incident, and it was noted that no reportable quantities should have been exceeded. A site visit did not occur for 3 days and photos were taken from the cabin of the car.
