Point Source(s):
308F-D-1 (Low Pressure Flare); 308F-D-2 (High Pressure Flare); 191-FF (191-PSV-009A); 191-FF (191-PSV-011)

Hydrogen Sulfide - 5 pounds
Hydrocarbon - 150,428 pounds
Nitrogen Oxide - 5 pounds
Cause of Problem: Equipment Failure

On 11/19/09, the refinery "experienced an unexpected internal electrical power phase to ground fault." This fault caused a power interruption from internal Substation 5D to the Crude Unit 191 and resulted in the loss of most of the Crude Unit's pumps and several fin fans causing a major unit upset and emergency shutdown. These upset operations subsequently caused the Atmospheric Tower's pressure relief valve (191-PSV-009A) to open to protect the upper section of the Atmospheric Tower. An attempt to circulate the liquid inventory in the Vacuum Tower (VT) back to the Crude Tanks caused as unexpected high liquid level and the VT pressure relief valve (191-PSV-011) opened up to protect the upper section of the VT. This relief valve relieved vapors, liquid hydrocarbons, and crude oil from a vent at the top of the VT. The loss of the Crude Unit forced most of the refinery's process units to shutdown resulting in intermittent flaring. Following the shutdown and the re-establishment of power to substation 5D, the process of restarting several refinery units was initiated. The Coker Unit's Compressor (891-K-1) motor amp limit controller (PJC-404) unexpectedly opened the flare valve (PPC-998) due to a very high motor amperage surge at its initial start. Flares smoked intermittently throughout shutdown and startup events. Fenceline monitoring indicated "no offsite impact." Fenceline monitoring
Immediate: Units were shut down until electrical supply was repaired. After a formal investigation, the cause of the incident was determined to be a loose connection between the bus and runback rod that put enough electrical load on the connecting bolt to melt it thus creating the ground fault. Connecting bolts are now inspected and replaced as necessary, COP electricians are being further trained, and a QC checklist and testing procedures to verify proper electrical connections have been implemented. Discharge classified as "Extremely Hazardous Substance" Regulated by OSHA HazCom

2008-09-24
Point Source(s):
1792-FF

Pollutant(s):
Benzene - 10 pounds
Cause of Problem: Weather

Valve leak during start up of petro chemical unit THD-1792 after Hurricane Gustav.

No Information Given

2008-09-21
Point Source(s):
591-D-21 (Sulfur Recovery Unit Incinerator)

Pollutant(s):
Sulfur Dioxide - 787 pounds
Cause of Problem: Weather

Startup after Hurricane Gustav
*Same State Police number as an incident on 9/19/2008, but different NRC and LPEC numbers. Unsure if itŐs a separate incident or related. No LDEQ report.* Non-optimal shutdown performed prior to the Hurricane Gustav evacuation inorder to reduce emmisions during shutdown. There was insufficient time to perform 4-6 process to remove residual sulfur to As a result residual sulfur was released directly to the incinerator during startup.
109347

2008-09-19
Point Source(s):
308F-D-1 Low Pressure FLARE

Pollutant(s):
Sulfur Dioxide - 206 pounds
Cause of Problem: Weather

High pressure in the Sulfur Recovery Unit 591 resulted in part of the acid gas (Hydrogen Sulfide) feed to be routed to the Low Pressure flare. Sulfur dioxide did not exceed reportable quantities. No mention of Hydrogen sulfide emissions in report.
109316

2008-09-18
Point Source(s):
591-D21 (SRU incinerator)

Pollutant(s):
Sulfur Dioxide - 1,906 pounds
Cause of Problem: Weather

Restarted in "cold" start-up mode after Hurricane Gustav.
Due to hurricane start up Tail Gas Treater Unit (TGT) and Sulfur Recovery Unit (SRU)started up at the same time, rather than with the TGT already running. This sent more gases than usual directly to the incinerator causing increased emissions. Units were stabilized.
109108

2008-09-16
Point Source(s):
Wastwater Collection System (EQT 088-308 WWTP)

Pollutant(s):
Hydrocarbon - 336 gallons
Cause of Problem: Weather

Flooding caused by Hurricane Gustav caused oil from sewers to overflow to ground areas.
Oil spilled onto soil and vegetation in facility. Culverts leading to navigable waters were closed off and oil was confinded to ditch. Vaccum trucks picked up free oil in ditches and booms and spill pigs deployed to contain the oil.
109428

2008-09-14
Point Source(s):
308F-D-1 Low Pressure FLARE

Pollutant(s):
Sulfur Dioxide - 1,506 pounds
Cause of Problem: Weather

Dduring start up of Coker unit after Hurricane Gustav evacuation
Extra material was stored in the Coker Feed Tanker to prevent solidification and pluggage of the Coker unit feed system after Hurricane Gustav. This also caused higher than usual pressure in the Coker Fractionator Overhead and the Compressor suction drum (891-V-15), which caused the flare vlave to open. Compressor turned on but flaring continued until material was released from feed and no longer affected the overhead.

Point Source(s):
308F-D-1 Low Pressure FLARE, 308F-D-2 High Pressure FLARE

Pollutant(s):

Cause of Problem: Weather

Shut down and evacuation in preparation for Hurricane Gustav and Ike.
Flaring and venting occurred but emissons did not exceed permit quanitities. Oily water sewers overflowed due to pump failure from power outages. Oil spilled to ground, water and pavement. Estimated 80 barrels recovered in cleanup. This incident will be critiqued and lessons learned will be used to update refinery's hurricane plan.
