During the activation ofthe catalyst in Unit 20, Dimethyl disulfide was added,to' Unit 20 at a rate of5 gallons per minute (gpm) per operating procedures: The acid gas that was: created during catalyst activation was sent to Unit 16 and Unit 17 for treatment and overwhelmed the units,

Steps Taken to Control Emissions: After the upset condition in Unit 16 and 17 were identified, the feed ofDimethyl disulfide to Unit 20 was cut to 1 gpm to reduce acid gas formation. Unit 17 was started up as quickly as possible after both interlocks After the SRU was stabilized on acid gas feed, the sour water stripper gas was reintroduced into the unit. All excess sour gas was combusted in the flare to prevent direct venting to the atmosphere. 

### In accordance with AO**DAQE-ANOI0l230023~7**

### Affected Units: Amine Treatment Unit (Unit 16). SRU (Unit 17), Sour Water Stripper (Unit 18), North Flare Cause and Nature ofEvent: The,SRU'had been exhibiting signs ofpartial plugging through the unit as the differential pressure 

### in the 'unithad increased. It 

### was discovered that the second leg of the 

### reactor was plugged due to a steam trap malfunction. As a result ofthe plugged leg, pressure increased in the reactor and acid gas was vented to the flare.;

### Duration ofEvent: Acid 

### gas was routed to the North Flare on February 27, 2009 from 12: 12 to 15:49. The total duration ofthe event 

### was 3 hours and 37 minutes. Estimated Quantity ofPollutants Emitted During the Event:

Steps Taken to Control Emissions: When the source ofthe plugging 

### in the unit was discovered, the problem was quickly resolved. The steam trap was repaired and the increased temperature cleared the blockage. Unit 18 was shutdown to decrease the amount ofgas being feed into the SRU. The decreased feed to the SRU relieved the excess pressure 

### in the unit and prevented the acid gas from going to the flare. All excess acid gas was combusted
