128363

2010-12-29
Point Source(s):
T-6020 wastewater degas tank

Pollutant(s):
Wastewater - 0
Cause of Problem: Weather

HEAVY RAIN. Leaking partially treated wastewater tank in the process of being taken out of service was overwhelmed due to heavy rains--formerly controlled outflow that was moving leaked material back into the treatment system overflowed into a solids settling pond. "Water quality impact is minimal due to this incident because the solids will settle into the pond before discharge."
Leak was ongoing at time of report at a rate of about 33 gal/min. "Once the rainfall slows down, all surface water will be contained and treated in the primary waste water treatment system." Release was ongoing at time of report. LDEQ report only. No refinery letter.

2010-12-07
Point Source(s):
amine gas feed line to #1 ECC

Pollutant(s):
Hydrogen Sulfide - 1,050 pounds
Sulfur Dioxide - 1,050 pounds
Cause of Problem: Piping or Tubing

Leak on the amine gas feed line pipe at the #1 ECC #1 sulfur recovery unit. LDEQ report states that "leak was originally discovered when an internal H2S monitor picked-up an unknown quantity from inside the refinery."
Feed taken out of the line and nitrogen introduced to purge amine gas; #1 SRU unit shut down; line replaced.

2010-10-25
Point Source(s):
Sulfur Recovery Unit (SRU)

Pollutant(s):
Sulfur Dioxide - BRQ
Sulfur Trioxide - BRQ
Cause of Problem: Process Upset

Upset in the sulfur recover unit; the "tail gas unit experienced a foaming incident," which allowed SO2 and SO3 to escape into the atmosphere.
No information given

2010-10-02
Point Source(s):
West flare EQT330

Pollutant(s):
Sulfur Dioxide - 949 pounds
Cause of Problem: Process Upset

"During start-up of the HDC [hydrocracker] unit, the amine contactor foamed leading to amine carryover and a high liquid level in the knockout drum which shutdown the recycle hydrogen compressor and triggered depressurizing of the unit to the flare." SO2 release above permitted amounts of 500lbs/hr but below RQs Flame carryover from flaring resulted in a "small" grass fire along the right-of-way of PPG Drive which was extinguished by the Westlake Fire Dept.
"Amine flow to the contactor has been reduced from typical to prevent recurrence."

Pollutant(s):
No Information Given - 0
Cause of Problem: Piping or Tubing

2010-09-10
Point Source(s):
piping on Pump P-20038

Pollutant(s):
Heavy Vacuum Gas Oil - 2,562 gallons
