|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|Flares 1 and 2, Thermal Oxidizer||Cause: power interruption causes upset at East Plant and multiple emissions. Design used purchase power instead of UPS power|
Notes: Immediately stabilized process units. Provide uninterruptable power supply instead of purchased power supply to the combustion blowers. PSSR electrical check list will be revised to add a step to physically shut off power to the equipmt to verify that UPS is working properly.
|Sulfur Dioxide: 930.0 pounds|
|Tank T-118||Cause: A spill of oily solids was discovered at tank T-118. The tank manway was removed as planned to facilitate solids removal from T-118 which had been removed from service for several weeks adn was undergoing cleaning.Accumulated solid material in the tank shifted and released oily solids to the ground and outside of the work containment area.|
Notes: Refinery personnel utilized absorbent boom to contain the material within the gravel area and mobilized spill response personnel to assist in containing the material.
|Oil and Process Waste Water: 399.0 gallons|
|FCCU||Cause: Stack testing of the FCCU revealed higher than federally permitted release rates and reportable quantities of hydrogen cyanide gas.|
Notes: A permit notification will be submitted representing this new data and request an increase in emissions. Testing showed hydrogen cyanide release at 90 lbs/hr. No duration time was given, because emissions are ongoing. Release amount for this database represents one year of HCN emissions and was calculated using the hourly release rate (90 lbs/hr) multiplied by 8,760 hours/year.
|Hydrogen Cyanide: 788,000.0 pounds|
