2010-12-30
Point Source(s):
No Information Given

Pollutant(s):
Wastewater - BRQ
Cause of Problem: Weather

Initial notification to report potential permit exceedances for permits: LPDES LA0039390 - due to excessive rainfall. Written report states that "thankfully it appears at this time none of the parameters listed in [permit] were exceeded. Placid was able to manage the excessive water and no by-pass condition was necessary."
BRQ. No information given.

2010-12-18
Point Source(s):
No Information Given

Pollutant(s):
Hydrocarbon - 0
Cause of Problem: Under Investigation

Transport truck loading at placid Refining Company truck rack caught on fire. Due to the large volume of water used, water,foam and residual hydrocarbons migrated off site into drainage conveyances to the East and to the South of the refinery. Cause is under investigation. FIRE.
Placid's automated fire suppression systems activated and extinguished the fire within five minutes. The drainage ditch was blocked using various mechanical methods including sorbent booms and a sand dike to prevent more migration. Still under investigation. Refinery letter only. No LDEQ report included.

2010-12-01
Point Source(s):
Process Unit

Pollutant(s):
Sulfur Dioxide - 0
Cause of Problem: No Information Given

LDEQ states that a loss of hydrogen caused the shutdown of several process units. Sulfur dioxide was re-routed to the incinerator.
No Information given. As of June 2011 incident is still classified as "open" by LDEQ. LDEQ report only. No refinery letter.
127340

2010-10-28
Point Source(s):
FLARE: Boiler & Flare Stack (EPN 18-74 EQ016)

Pollutant(s):
Sulfur Dioxide - 4,351 pounds
Cause of Problem: Equipment Failure

Refinery letter states that due to a low waste heat boiler level, flaring occurred. Fire eye problems caused the plant to be shut down longer than expected. Refinery letter states that "it should be noted that flaring continued for approximately one hour and seven minutes more due to the Flare Gas Recovery System being shut down during acid gas flaring. However, during that time, no sour material was flared." FLARE.
RQ. Reportable quantities were exceeded. Bridles were cleaned.
126184

2010-09-07
Point Source(s):
Tank 17 - flange on an oil transfer line

Pollutant(s):
Gas Oil - 294 gallons
Cause of Problem: Equipment Failure

A flange on an oil transfer line south of Tank 17 was discovered leaking gas oil which is a heavy hydrocarbon.
RQ. Reportable quantities were exceeded for gas oil. The line was blocked, the dike area was also blocked, and the spill was contained with absorbent pads, boom and a vacuum truck.

2010-09-02
Point Source(s):
FLARE: FCCU Unit

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

Flaring resulting from planned FCCU start-up. FLARE.
BRQ. Refinery letter states that no reportable quantities were exceeded. No additional information given.
126110

2010-08-28
Point Source(s):
FLARE: FCCU Unit

Pollutant(s):
Sulfur Dioxide - BRQ
Cause of Problem: Equipment Failure

Flaring due to unexpected FCCU shutdown due to a malfunctioning flapper valve, which caused catalyst carryover. FLARE.
BRQ. Refinery letter states that no reportable quantities were exceeded. No additional information given.
126002

2010-08-28
Point Source(s):
FLARE: FCCU Unit

Pollutant(s):
Hydrocarbon - BRQ
Cause of Problem: Equipment Failure

BRQ. No information given.
125903

2010-08-24
Point Source(s):
FLARE: FCCU Unit

Pollutant(s):
Sulfur Dioxide - BRQ
Cause of Problem: Equipment Failure

Flaring of slightly sour stream due to unexpected shutdown of FCCU because of air blower failure. No information given re: what was released. FLARE.
BRQ. Refinery letter states that calculations determined that no reportable quantities were exceeded. No information given.
124744

2010-07-12
Point Source(s):
FLARE:Catalytic Hydrotreater, SRU #2 & #3 [EPN 18-74]

Pollutant(s):
Sulfur Dioxide - 12,681 pounds
Cause of Problem: Human Factors

Power failure caused shut down of Catalytic hydrotreater, Sulfur Recovery Units # 2 and # 3 and resulted in flaring acid gas and sour water gas...and 12,681 lb SO2 emissions. ROOT CAUSE was an "errant setting on the Feeder Management Relay for Powerhouse 11. The relate was set to trip on an instantaneous over current to neutral."
RQ. Refinery letter states that "setting was disabled in the relay to prevent future errant power interruptions." LDEQ report states that incident will "be taken up at the next scheduled inspection. Need calculations and whether it could have been prevented the duration."

Point Source(s):
FLARE: FCCU & sour water stripper
FLARE: FCCU and sour water stripper

Pollutant(s):
Carbon Monoxide - BRQ
Volatile Organic Compounds (VOCs) - 94 pounds
Sulfur Dioxide - 727 pounds
Cause of Problem: Maintenance/Procedures

"FCCU shut down to replace packing on Regen Slide valve." Flaring occurred upon restart of unit. FLARE.
RQ. Incident exceeded reportable quantities for sulfur dioxide. LDEQ report states that incident investigation status is "deferred until next inspection." No information given regarding remedial actions. LDEQ report only. No refinery letter.

Point Source(s):
No Information Given

Pollutant(s):
None - BRQ
Cause of Problem: Maintenance/Procedures

Pollutant(s):
No Information Given - BRQ
Cause of Problem: Maintenance/Procedures

"Unscheduled maintenance requiring shutdown of FCC Unit. The packing on the slide valve stem in the regenerator side of FCCU failed and had to shut down the unit and flaring ensued." No details given regarding what was emitted. FLARE.
BRQ. Refinery letter states that no reportable quantities were exceeded during this incident. Valve removed and sent for repair.
