Notification: Thefollowing notifications weremade: Kelly Gallagher made notifications at 9:45 a.m. the State Emergency Response Committee (SERC) and the Local Emergency Planning Commission (LEPC). 

### In addition, a courtesy notification was made to the Division of

### Air Quality (DAQ) at the same time. All notifications were made onJanuary 4, 2008.
AffectedUnits: AmineTreatment Unit (Unit 16), SRU (Unit 17), SourWater Stripper (Unit 18), NorthFlare
Cause and Nature ofEvent: Wehavebeen experiencingfoaming inthe amine unit regenerator that causes upset 

### in that unit, and have been investigating the potential causes of foaming so that we may eliminate them. At approximately 5:00 p.m. on January 4 we experienced one such foaming event. The resulting fluctuations in acid gas from the amine unit cause an interlock inthe SRU
Duration ofEvent: As a result ofthe interlock, acid gas was routed to the flare from 5:42 p.m. until 7:46 p.m. Sour water stripper gas was sent to the flare from 5:14 p.m. until 8:18 p.rn. The total duration ofthe event was 3 hours'S minutes.

### 2600 North Flare Steps Taken-fa-Control Emissions: Operations personnel continued to stabilize the operation ofthe amine unit, then restarted the SRU. Once 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

### ,.,....,..---··--·Th~·-H~S j-hour average concentration limit of 160ppmv for plant fuel gas was exceeded for two hours. This exceedance was due to the high hourly concentration averages during the hours ending at 02:00 and 03:00. During those hours the refinery was without power andplant fuel gas was not being created. Plant fuel gas was not being used because the heaters and boilers were offline.

### RE: Reportable Event September 19-20, 2008 Unavoidable breakdown ofequipment To WhomIt May Concern: 

### In accordance with the Emergency Planning and Community Right-to-Know Act (EPCRA), 40 CPRPart 355; and the Comprehensive Environmental Response, Compensation, andLiability Act (CERCLA) 40 CFR 302.6, Holly Woods Cross Refinery notified your offices ofexcess emissions thatresulted from an unavoidablebreakdown ofour SulfurRecovery Unit (SRU). Notification: Roy Helmick ofHolly attempted to notify the StateEmergency Response Corrunittee (SERC) and notified the Local Emergency Planning Commission (LEPC). Ralph Johnson contacted the Utah Division ofAir Quality (UDAQ). The following table details notifications for this event.

UDAQ SERC LEPC Harold Burges No answer. Voice mail-Brent Peters Reported equipment breakdown. None (3 attempts)

.. Left a message. 9/25/200813:00 9/19/2008 15:37 9/1912008 15:40

Affected Units: Amine Treatment Unit (Unit 16), SRU (Unit 

### 17), Sour Water Stripper (Unit 18), North Flare Cause and Nature ofEvent Preliminary results from the investigation indicate that the SRU shutdown because the tail-gas incinerator flame detector gave false readings to the unit control system. The readings from the detector triggered an automatic shutdown interlock ofthe incinerator. This resulted in a time-out interlock of the thermal reactor that ended in the shut down ofthe entire unit. Duration ofEvent: Acid gas and sour water stripper gas were routed to the North Flare starting September 19, 2008 at 6:56 and ending September 20, 2008 at 17:38. The total duration ofthe event was 34hours and 42 minutes.Septembef25,2008 Mr,'Neil Taylor, Sgt. Brent Peters Page 2**~.** ;**~.~** , Estimated Quantity of-Pollutants Emitted During theEvent:

Steps Taken to Control Emissions: The operators attempted to restart the tail-gas incinerator several

. time·s. Maintenance was called out to assist. 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. Afterrepairs were made, feed streams wererouted backto the SRU during the unit's startup, Please contact me with any questions or comments at (801) 299-6619. I canbe reached by email at ralph.johnson@hollycorp.com. Sincerely,
