Tank 181
Cause: Tank 181 was over run and released 25 barrels of P-80 to the ground. It was contained within the tank berm.

Followup: No

Notes: The cause notes said that operational procedure was not followed, making it appear to be human error.

overflow pipe
Cause: On February 27, 2014 at approximately 13:20, an overflow pipe was discovered on an underground oil/water separator at the East tank farm. The level transmitter that controls oil/water separator level malfunctioned at the sump, which resulted in oil backing up in the system and released of crude oil to the ground. The release impacted an area of 20 ft by 40 ft.

Followup: No

Notes: Immediate corrective action was to start pumps manually and repair the level controller. 10 cubic yards of waste was excavated and disposed at Woolworth landfill. At the time of inspection by LDEQ, stained soil spots were noted at various areas at the East Sump Separator due to historic contamination.
Slop Oil: 168.0 gallons

Cause: It was reported on January 7, 2014 that boilers shut down due to the level transmitter freezing up, therefore there was not enough steam to run the amine unit. Sulfur built up in the fuel gas and caused sulfur dioxide to be released into the atmosphere.

Followup: No

Notes: According to the Field Interview Form from LDEQ, the same problem occurred the day before on January 6, 2014. On January 7, 2014, a release of 520 pounds of sulfur dioxide was reported. The field interview form states that approximately 895 pounds of sulfur dioxide was released during the incident. Field interview form also states that there was an average concentration of 1680 ppm hydrogen sulfide during the accident. No other documents available for this incident besides the Field Interview Form.
