LDEQ Accident Number Accident Date	Point Source/Release	Cause	Notes
92878 2006-12-24	Point Source(s): Conservation vents Tank 55-5(EQI No. 44-74/EQT No. 104) Pollutant(s): Butane - 135 pounds	Cause of Problem: Instrument Failure Tank 55-5 high pressure equal to 2 inches of water column caused the tank conservation vents to open to the atmosphere. The pressure transmitter failed giving a false low pressure in tank 55-5.	Currently under investigation. BELOW REPORTABLE QUANTITY.
91854 2006-11-03	Point Source(s): Relief Valve 56-PSV-7008 Pollutant(s): Distillate - 14 pounds	Cause of Problem: Maintenance/Procedures Computer Process Controls going on at this time are believed to have been the initial cause of the Relief Valve relieving to the atmosphere.	Does not have an additional report of the actual totals of what was spilled. Steam up on relief valve to minimize emissions. BELOW REPORTABLE QUANTITY.
91732 2006-10-28	Point Source(s): Unit 37 Cooling Tower Pollutant(s): Sodium Hypochlorite - 200 pounds	Cause of Problem: Piping or Tubing PVC suction line pipe broken (s06-3392) from the cooling system tower releasing 200 gallons of Sodium Hypochlorite Solution into the surrounding soil.	Sodium Hydrochlorite tank in Unit 37 Tower area. The material was cleaned as soon as possible.
91306 2006-10-12	Point Source(s): No Specific emission point associated with this spill Pollutant(s): Sodium Hydrochlorite - 2,976 pounds	Cause of Problem: Piping or Tubing A 3/4 inch PVC hose fitting failed on the pump suction from the temporary sodium hydrochlorite tank/under investigation	Currently under investigation.
No LDEQ Number Available 2006-10-08	Point Source(s): Alky Cooling Tower (EIQ 61-74/ EQT 043) Pollutant(s): Butane - 40 pounds	Cause of Problem: Piping or Tubing A pin hole leak was found on the on the Alky C4 Overhead Condenser, which affected the allky cooling tower.	BELOW REPORTABLE QUANTITY.
90703 2006-09-15	Point Source(s): Butamer Trim Cooler (28-1305-01) had a leak into FCCU Cooling Tower (EIQ 123-91/EQT 049) Pollutant(s): Isobutane - 316 pounds	Cause of Problem: Piping or Tubing The Butamer Trim Cooler was found to have a pin-hole leak and was leaking into the cooling water, which affected the FCCU Cooling Tower.	Unit shut down to locate the source of the leak, but no remedial action was taken to prevent reoccurrence. BELOW REPORTABLE QUANTITY.
89533 2006-07-26	Point Source(s): South Flare (EQI No. 69-74/EQT 160) Pollutant(s): Sulfur Dioxide - 26 pounds Hydrogen Sulfide - 0 pounds	Cause of Problem: Equipment Failure The Absorber Reboiler was leaking hot gas into the Hot Oil Surge Drum causing it to overpressure.	BELOW REPORTABLE QUANTITY.
88771 2006-06-21	Point Source(s): Propylene Cooling Tower (EQI No. 123-91/EQT 49) Pollutant(s): Propylene - 639 pounds Propane - 213 pounds	Cause of Problem: Equipment Failure The C3/C4 condenser was leaking product into the cooling water.	The cooling system associated with propane tower is being evaluated.
88629 2006-06-14	Point Source(s): Propylene Cooling Tower (EQI No. 123-91/EQT 49) Pollutant(s): Propylene - 493 pounds Propane - 164 pounds	Cause of Problem: Equipment Failure The C3 Product cooler was leaking on the cooling water side.	None.
88512 2006-06-10	Point Source(s): Flaring from Unit 21 Absorber and North Flare (EQI No. 83-74/EQT 162) flaring from fuel gas mix drum Pollutant(s): Volatile Organic Compounds (VOCs) - 2,353 pounds Highly Reactive Volatile Organic Compounds (HRVOCs) - 10 pounds Sulfur Dioxide - 0 pounds Volatile Organic Compounds (VOCs) - 14 pounds Highly Reactive Volatile Organic Compounds (HRVOCs) - 7 pounds	Cause of Problem: Process Upset Shell, Norco, had an unexpected shutdown of one of their units which processes Marathon Petroleum Company off gas, MPC had to flare excess off-gas/ fuel gas during this time.	BELOW REPORTABLE QUANTITY.
87670 2006-05-08	Point Source(s): Leaking flange gasket in distilate hydrotreater Pollutant(s): Hydrogen - 20 pounds Nitrogen - 9 pounds Hydrogen Sulfide - 0 pounds	Cause of Problem: Seal or Gasket During startup of the distillate hydrotreatmer, a flange gasket on a manway of the recycle gas amine scrubber was found leaking.	BELOW REPORTABLE QUANTITY.
85928 2006-02-19	Point Source(s): The North Flare (EIQ No. 83-74/EQT 162) Pollutant(s): Propylene - 2 pounds	Cause of Problem: Process Upset During maintenance a valve was opened to the flare to reduce the amount of ethanes contaminating the purity of the propylene.	BELOW REPORTABLE QUANTITY.
85091 2006-01-11	Point Source(s): The North Flare (EIQ No. 83-74/EQT 162) Pollutant(s): Olefins - 79 pounds Volatile Organic Compounds - 252 pounds Sulfur Dioxide - 211 pounds	Cause of Problem: Equipment Failure The uninterpretable power supply failed, causing a shutdown of the FCC unit.
84997 2006-01-06	Point Source(s): Flange near the Crude Bottoms Pump in the Crude Unit Flange near the Crude Bottoms Pump in the Crude Unity Pollutant(s): Sulfur Dioxide - 2,039 pounds Volatile Organic Compounds - 121 pounds	Cause of Problem: Equipment Failure While preparing the Crude Unit for Turnaround activities a fire occurred. It is assumed that the bolts on the flange of a crude pump opened and products was released. The exact cause is still under investigation, but it is assumed that one of the isolation valves were leaking.	MPC assumed the entire amount of the sulfur present was combusted even though there was substantial product left on the cement of the unit.
