Accident Classified As: Reportable Quantity
Loss of power triggered upset of refinery and shutdown of the refinery's operating sulfur recovery unit.
Due to the work begin conducted by Entergy, the refinery claims that the release was not preventable by refinery personnel. Investigation of the incident by refinery personnel indicated that external power supplied by Entergy was lost due to activity external to refinery operations.
A power outage and refinery shutdown resulted in flaring, including a release of Sulfur Dioxide, Hydrogen Sulfide, Nitric Oxide, and Nitrogen Dioxide beginning 12/5/05 and continuing intermittently during the repair of equipment damaged by the outage. The power outage occurred when Entergy was doing some work at the Meraux substation. The entire refinery lost power. The units are now back on line but at minimal rates while repairs are being performed. The refinery is still flaring S02 and H2S because there was damage to the sulphur plant. Operations were conducted in order to minimize emissions while maintaining a safe and orderly stabilization of refinery operation and restart of some refinery process units. Refinery Management has met with Entergy to stress the impact of this incident and request that appropriate measures be taken in order to prevent a recurrence. Operations were conducted in order to minimize emissions while maintains a safe and orderly stabilization of refinery operations and restart of some refinery process units. This is clearly far exceeding the reportable quantity for sulfur dioxide (RQ=500 lbs).
