89447 2006-07-24	Point Source(s): St. Rose Flare Pollutant(s): Benzene - 0 pounds Carbon Monoxide - 14 pounds Nitrogen Oxide - 3 pounds Particulate Matter - 1 pounds Sulfur Dioxide - 2 pounds Toluene - 0 pounds Volatile Organic Compounds - 11 pounds Xylene - 0 pounds n-Hexane - 1 pounds	Cause of Problem: Power Failure Unexpected failure of Entergy power supply resulting in flaring material from the crude column overhead system	Improvements to power supply are current project
No Information Given 2006-07-02	Point Source(s): St. Rose Flare Pollutant(s): 1,3-Butadiene - 0 pounds Benzene - 0 pounds Carbon Monoxide - 48 pounds Ethylbenzene - 0 pounds Hexane - 0 pounds Nitrogen Oxide - 9 pounds Particulate Matter - 2 pounds Toluene - 0 pounds Volatile Organic Compounds - 7 pounds Xylene - 0 pounds	Cause of Problem: Power Failure Electrical power dip which led to a pump shutdown and causing the de-salter to overpressure resulting in a pressure relief valve opening up and material vented to the flare	Pump restarted. Improvements to power supply are current project
88859 2006-06-24	Point Source(s): St. Rose Flare Pollutant(s): Carbon Monoxide - 1 pounds Nitrogen Oxide - 0 pounds Particulate Matter - 0 pounds Volatile Organic Compounds - 0 pounds	Cause of Problem: Power Failure Unexpected failure of the Entergy power supply which resulted in the shutdown of the K-8508 compressor. When the compressor shut down, material was automaticallydiverted to flare	Unit was depressured until the power was restored. Improvement in the St. Rose electrical supply are subject of a current project.

The pilot was designed to withstand inclement weather conditions.An investigation will be conducted on the flare tip & pilot to understand why it went out. St. Rose flare is 200 feet tall.
85779 2006-02-12	Point Source(s): GO-1 Elevated Flare Pollutant(s): Carbon Monoxide - 22 pounds Hexane - 3 pounds Nitrogen Dioxide - 37 pounds Particulate Matter - 7 pounds Sulfur Dioxide - 1,587 pounds Volatile Organic Compounds - 8 pounds	Cause of Problem: Other In order to control the differential pressure, untreated dry gas was sent to the fuel gas system and the remaining amount was flared.	Incident involving the DEA treatment system is the subject of an ongoing investigation. Corrective actions will be implemented.
