Cause of Problem: Start Up, Shut Down

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 Preventable - No

Discharge was not preventable due to "unanticipated pluggage."

Notes/Remedial Actions

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."
