Accident Classified As:
A notification for the controlled shutdown of the entire plant was made on January 7, 2009. On January 8, the Sulfur Recovery Unit/Tail Gas Treater (SRU/TGT) was determined to have pluggage issue that precipitated the premature shutdown of the SRU/TGT. This led to flaring and SO2 emissions. The loss of the SRU/TGT required the initiation of a controlled shutdown of the remaining process units which contributed additional Sulfur Dioxide emissions.
Discharge was not preventable due to "unanticipated pluggage."
An immediate shutdown was conducted of refinery process units. An investigation of the SRU upset is in progress and "will be reported in a subsequent letter."
