LDEQ Accident Number Accident Date	Point Source/Release	Cause	Notes
151683 2013-10-17	Point Source(s): tank 8553 Pollutant(s): Benzene - 3 pounds Ethylbenzene - 0 pounds n-Hexane - 12 pounds Hydrogen Sulfide - 1 pounds Xylene - 0 pounds Toluene - 2 pounds Volatile Organic Compounds (VOCs) - 1,271 pounds	Cause of Problem: Instrument Failure On October 16, 2013 at 1600 hours, the St. Rose operators discovered that a naphtha tank, Tank 8553, transferring naphtha landed on the roof legs. The radar gauge that was being used to monitor the level was believed to have been reading incorrectly; approximately 3 feet higher than the level should have been reading.	Once the operators discovered that the tank landed on the roof legs, the transfer from Tank 8533 was immediately stopped, and product was allowed to gravitate back into the tank until the roof was floated off the legs. Currently, an investigation is occurring. The results from this investigation will be incorporated, where applicable, to prevent recurrence.
