118804

2009-10-17
Point Source(s):
flare #2

Pollutant(s):
Sulfur Dioxide - 1,172 pounds
Cause of Problem: Instrument Failure

Level indicator in the Light Ends Plant over head had malfunctioned. Causing the #3 Pretreater and Hydrocracker (HCU) 1st Stage Stripper overhead off gas flow to suddenly decrease. This caused the pressure to increase and release emissions through flaring (#2).
Lowered drum level and stablizied the HCU and PT 3. Repaired indicator by refilling leg with glycerin.

117581

2009-08-25
Point Source(s):
Tank 301

Pollutant(s):
Sweet Crude Oil - 8,283 gallons
Sweet Crude Oil - 1,499 gallons
Benzene - 15 pounds
Cause of Problem: Maintenance/Procedures

Cinatra (3rd party contractor) was performing a tank (301) cleaning procedure that involved the circulation of oil with high pressure nozzles. The coupling failed on a supply line that was located on the tank's roof where it spilled oil.
Stopped circulating oil through the cleaning system and roof drain was closed. Spilled material contained in dike area and recovered by a vacuum truck for reprocessing. Impacted soil was removed.
117083

2009-08-06
Point Source(s):
SRU 1 and 2

Pollutant(s):
Sulfur Dioxide - 1,136 pounds
Cause of Problem: Start Up, Shut Down

Sulfur Recovery Unit Train (SRU 2) shutdown due to a steam excursion in the refinery. The steam excursion had caused the SRU 2 to shutdown from low boiler water level. The acid gas loading from SRU 2 was added to SRU 1 which caused the emissions. A second incidence occurred when the refinery lost its hydrogen supply from Air Products. This caused the shutdown of the refinery hydrotreaters and a significant decrease in refinery acid gas production. SRU 1 shutdown due to the insufficient acid gas leading to a second emission.
acid gas was routed from SRU 2 to SRU 1. Acid gas flaring was avoided and DGA strippers was contained until SRU 1 was restarted. SRU 1 was run at minimal air flow rates to avoid excess H2S consumption due from insufficient acid gas rates. Caustic addition was maximized in tail gas section to mitigate additional SO2 formation.
116878

2009-07-29
Point Source(s):
abandoned line

Pollutant(s):
Asbestos - BRQ
Cause of Problem: Maintenance/Procedures

116591

2009-07-20
Point Source(s):
Desulphurization unit clamp

Pollutant(s):

RQ not exceeded.
116493

2009-07-14
Point Source(s):
outfall 013

Pollutant(s):
Hydrofluoric Acid - 3,257 pounds
Cause of Problem: Piping or Tubing

While an operator was back flushing the HF Alky Unit's heat exchanger, a leak was discovered on the heat exchanger. The heat exchanger released chemicals into the cooling water system (outfall 013) which was subsequently released to the Mississippi River.
The Alkylation Unit was shut down. The rates were reduced and the acid was evacuated from the unit. Fluoride samples were measured from the cooling water effluent throughout the shutdown of the unit. The pH of outfall 013 was monitored. Root cause of the leak is being investigation, and the follow up should have been filed.
116460

2009-07-13
Point Source(s):
pipeline to Tank 300

Pollutant(s):
Sweet Crude Oil - 2,997 pounds
Sweet Crude Oil - 296 pounds
Cause of Problem: Corrosion

During the unloading of a crude oil ship, there was a 3/4" bleeder that had become dislodged from the line during transfer. However in subsequent investigations, they found that the nipple on the crude line had failed due to internal corrosion which was the root cause of the release.
Had 2 follow up reports- August 28, 2009 and September 23, 2009. Operators stopped unloading and closed inlet valves to the line manifold and Tank 300. A drip pan was placed below the line opening and a vacuum truck was stationed by the drip pan to store the oil. The contaminated soil was also removed.
116434

2009-06-12
Point Source(s):
coker #2 coke pit and fire lanes

Pollutant(s):
Sulfur Dioxide - 3,569 pounds
Cause of Problem: Instrument Failure

Failure of the coker fines lane pump discharge check valve resulting from accumulated coke fines, which allowed oil from the coker cutting water tank to back flow into the fines lane. Once the oil came in contact with the hot coke in the pit, a fire resulted.
Fire was extinguished with foam. Secondary check valve was installed and a cautionary procedure was developed and implemented.
115487

Point Source(s):
hose from waste water tank

Pollutant(s):
Sludge - 0 pounds
Sulfur Dioxide - 267 pounds
Volatile Organic Compounds - 7 pounds

Cause of Problem: No Information Given

Unscheduled release of PSV lift, tanks 9000, 9006, and 9007.
RQ not exceeded.
114985

2009-05-14
Point Source(s):
flare

Pollutant(s):
Sulfur Dioxide - 2,138 pounds
Cause of Problem: Process Upset

High differential pressure across gas oil feed filters to Cat Feed Hydrotreater (CFHT) prevented feed from entering the unit. Loss of feed to CFHT combined with malfunctioned level indicator (instrument failure) in hot separator resulted in the total loss of liquid level in the hot separator. This created high pressure vapor from the hot separator that was fed to the fractionator. This result in the overheating and over pressuring of the fractionator and increased gas rates to the fractionator overhead.
RQ exceeded. CFHT rates reduced to a minimum and stopped using propane to minimize temperature and pressure excursions. Level indicator malfunction ocrrected by replacing the anti-freeze.
