|unspecified boilers and heaters||Cause: SRU unit down because scrubber was not cleaning gas fast enough. Caused rich gas to burn in the heaters and boilers, releasing SO2 to the atmosphere.|
Notes: #3 SRU started up to relieve problem.
|Sulfur Dioxide: 1,619.0 pounds|
|SRU Units||Cause: Both SRU units down due to a damaged expansion joint on the wet gas scrubber. There is a release of SO2.|
Notes: There is no information regarding amount of SO2 released. Replaced the expansion joint. LDEQ report only. No refinery letter included.
|FLARE: Flare #3||Cause: Two Sulfur Recovery Units tripped and became plugged. The SO2 was routed to the number 3 flare and released. Production was reduced.|
Notes: The SRUs were unplugged and repaired. There is no incident report in the file.
|Sulfur Dioxide: 14,160.0 pounds|
|None Reported||Cause: The amine unit has a frac tank that skims the amine out, and this tank's carbon canister (helps to filter the odor), was noted to be damaged that morning. During the replacement of the canister, the odor that was released was noticed by the citizen.|
Notes: The damaged canister was replaced, at which time the odor was released. Later that day, no odor was noted in the area.
|FLARE: Sulfur Recovery Unit (SRU)||Cause: LDEQ states that sulfur dioxide, exceeding 500 lb, was released to the #3 flare during an SRU failure. FLARE.|
Notes: RQ. Reportable quantities for sulfur dioxide were exceeded. The facility conducted air monitoring throughout the incident. Nothing was noted on the air monitors. LDEQ report and FIF only.
|Sulfur Dioxide: 9,297.0 pounds|
|FLARE: SWEPCO Transformer||Cause: LDEQ states that a blown SWEPCO transformer caused a plant wide power failure; sulfur dioxide was sent to the flare. FLARE.|

|Sulfur Dioxide: 500.0 pounds|
|Tank Farm||Cause: Spill of 5 barrells (210 gallons) of oil from the frac tank near 201 tank. Bad check valve and ball valve caused material to backflow through frac tank releasing crude oil to secondary containment|
Notes: The facility cleaned up oil with vac trucks and remediated the soil. They will replace faulty valves at equipment.
|Crude Paraffinic: 210.0 gallons|
|Pump at the lift station from the API unit||Cause: There were mechanical issues and seal failure with the main lift pump, which pumps to the waste water holding tank (T-79). The pump was taken out of service, during which time untreated process waste water from the grit separator flowed directly into the Aerated surface impoundments.|
Notes: Maintenance craftsmen made necessary repairs. There were failed attempts to start the backup belt-driven pump, but it cycled 3 times and lost prime, and operations was unable to re-prime it. As of 02/21/12, maintenance craftsmen were working with the repairs and were expected to complete them. The refinery letter advises that the bypass was not expected to cause any additional problems with effluent limits.
|Flare #2||Cause: At approximately 7 PM on May 2, a PSA compressor tripped, routing gas to Flare #2.|
Notes: No remedial actions taken. No exceedances resulted from incident and no emissions of reportable quantity were released. Gas was estimated to be 70 to 80 percent hydrogen. LABB was unable to locate a corresponding seven-day refinery letter.
|Flare||Cause: The facility flared for approximately 6 to 8 minutes around 2045 hours on April 12, 2013, releasing Sulfur Dioxide from the flare when the diesel hydrotreator compressor went down.|
Notes: This report was prompted by a concerned citizen reporting a Hydrogen Sulfide and Sulfur Dioxide odor around the entire perimeter of the Calumet Lubricants Plant in Shreveport. LADEQ report indicates that Calumet representative James Desonier stated no major incidences occurred that evening. He stated that flaring occurred for about 6 to 8 minutes releasing Sulfur Dioxide because of diesel hydrotreator compressor going down.
|Junction box||Cause: On April 10, 2013 for approximately one hour, 25 barrels (or 1050 gallons) of slop oil was released in the refinery tank farm area. This accident resulted due to a restriction in the line downstream of the junction box from a clogged pipe.|
Notes: Lab results from clean-up were received on May 7, 2013. The soil samples were tested for gasoline, diesel and oil. The diesel results were very high as noted in the LADEQ report dated May 14, 2013. Mr. Desonier Calumet Shreveport representative) stated that despite these high results, he did not plan on doing any more remediation.
|Slop Oil: 1,050.0 gallons|
|Sour crude unit #1 Atmospheric Tower Bottoms pump||Cause: Fire in the No. 1 Sour Crude unit due to failure of Atmospheric Tower Bottoms pump.|
Notes: Isolate unit and remove feed to stop fire. Use fixed monitors and deluge system to contain. Repair pump. Field interview was conducted by LDEQ on 5/27.
|Plant Boilers||Cause: The Facility lost the boilers due to the cold weather and the level transmitter froze up. When the boilers shut down, the whole plant shuts down. Therefor, there was not enough steam/ heat to operate the amine unit; the steam is used to regenerate the amine solution to scrub the sulfur out of the fuel gas. The amine unit is responsible for removing hydrogen sulfide and carbon dioxide from gasses. As a result, hydrogen sulfide derived from refining petroleum crude oil was allowed to build up in fuel gas. Sulfur dioxide was combusted out of the refinery heater stacks (CRG 0005) and released to the atmosphere. The fuel gas is used to fire all heaters and boilers in the plant facility-wide.|
Notes: Hydrogen Sulfide was reported to be at 190 ppm (BRQ) however it was later discovered to be 590 ppm ppm = parts per million
|Sulfur Dioxide: 559.0 pounds|
