77659 2005-03-17	No information given	Cause: Waste gas compressor number 2 (K-401) automatically shut down due to a high temperature. Followup: No Notes: Letter rescinds verbal report because incident was not reportable. No release to atmosphere.	42.0 pounds
05-BB005-135 2005-03-13	C-2307 (Second Stage High-Pressure Separator) level controller; K-2303 (HCU Second Stage Recycle Compressor)	Cause: During maintenance, the Hydrocracker (HCU) Second Stage High-Pressure Separator (C-2307) level controller was inadvertently left in the manual position. Later, HCU Second Stage Recycle Compressor (K-2303) shut down due to high level in C-2307. Shutdown of K-2303 caused automatic depressurization of C-2307 to the refinery flare system. Followup: No Notes: Letter rescinds report of Sulfur Dioxide because below reportable quantity.	176.0 pounds
05-BB005-128 2005-03-02	Waste Gas Compressor Number 4 (K-406); Copper tubing connecting C-435 (first stage suction drum) to high-level instrumentation	Cause: Waste gas compressor number 4 (K-406) shut down due to failure of piece of copper tubing connecting C-435 to high-level shutdown instrumentation. When it failed, a false high level reading was recorded, causing automatic safety shutdown system to become engaged. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize amount sent to the flare. C-435 was retubed, K-406 was checked and restarted.	182.0 pounds
76869 2005-02-11	No information given	Cause: From the verbal report: Followup: No Notes:	93.0 pounds
05-BB005-113 2005-02-07	Unintended over pressurization of the Hydrocracker Light Ends Plant (HCU LEP) Depropanizer surge drum	Cause: Due to the isolation of the sight glass of the hydrocracker light ends plant depropanizer, the automatic level indication equipment was disabled and false reading was transmitted; this condition caused an unintended over pressurization of the HCU LEP Depropanizer surge drum, which was venter to the refinery flare system (No. 2 flare) Followup: No Notes: Refinery personnel evaluated the process operation, identified the source of the problem and made appropriate corrections, ending the incident.	545.0 pounds
05-BB005-106 2005-02-04	Electrical breaker G-457; Waste gas compressor number 2 (K-401)	Cause: Electrical breaker for G-457 malfunctioned. Waste gas compressor number 2 (K-401) shut down as a result of the electrical power outage and refinery waste gas was diverted to safety flare system. Followup: No Notes: Low-Sulfur content streams were routed to the flare to minimize sour gas flaring. Output was adjusted to minimize total amount of waste being sent to the flare. Note: the breaker for G-457 had been identified for repair and was supposed to be replaced that week.	78.0 pounds
05-BB005-100 2005-01-24	Waste gas compressor shut down and caused an over pressure situation	Cause: From the verbal report: Followup: No Notes:	46.0 pounds
05-BB005-93 2005-01-22	K-406 (waste gas compressor number 4)	Cause: Waste gas compressor number 4 (K-406) unexpectedly shut down. Waste gas was automatically diverted to refinery safety flare system.

76362 & 76355 2005-01-21	Hydrocracker Light Ends Plant Butane Splitter Tower & LEP Depropanizer Tower Bottoms Flow Control Valve 50FC060	Cause: (1) 0600 hrs: Hydrocracker Light Ends Plant (LEP) Butane Splitter Tower began to overpressure because LEP Depropanizer Tower Bottoms Flow Control Valve (50FC060) had failed in the open position, letting propane to exit to the Butane Splitter. (2) 1700 hrs: Butane Splitter again began to overpressure due to the presence of propane. The level indication on the level instrument was detecting a false reading. Followup: No Notes: Letter speaks of two incidents on same day at 0600 hrs and 1700 hrs but attached report shows three incidents: (1) 4:05 a.m. lasting 3h 42m; (2) 3:15 p.m. lasting 41m; (3) 4:30 p.m. lasting 1h 25m. Amounts of compounds are only given in totals for all 3incidents.	452.7 pounds
76224 2005-01-18	No information given Number 2 Flare -- Pressure Safety Valve (PSV) on Fuel Drum for Number 10 Boiler	Cause: From the verbal report: Followup: No Notes:	1,805.0 pounds
05-BB005-67 2005-01-06	K-406 (waste gas compressor number 4)	Cause: K-406 unexpectedly shut down and waste gas was automatically diverted to refinery safety flare system. Followup: No Notes: Sweet streams (lower Sulfur content) were routed to the flare to minimize sour gas flaring. Process unit output was adjusted in order to minimize the total amount of waste gas being sent to the flare. Shortly after shutdown, personnel re-started K-406 restoring the systems ability to process available refinery waste gas streams, ending the incident.	14.0 pounds
