|Cause: Shut down and start up from Hurrican Rita|
Notes: Summary of releases over 31 days
|Wastewater Treatment Plant||Cause: while placing a line back into service athte h Wastewater Treatment Plant a relief valve overpressured and released oil to ground and surrounding ditches|
Notes: 5 gallons went into the Indian Marais. Booms, absorbent pads, vacuum tru
|Slop Oil Line||Cause: flange leak on 8 inch slop oil line due to failed gasket|
Notes: Gasket was replaced
|Outfall 006||Cause: see notes|
Notes: A pinhole leak was discovered on a 3 inch slop oil line upstream of the 006 slide valve structure. Leak was isolated and repaired. Slop oil spilled on soil, heavy rains produced a slight sheen at 006. Booms, absorbent pads and vacuum truck were deployedto contain the sheen. >30 gallons emitted according to Verbal Report. DEQ report attached to CITGO letter indicates that 190 lbs were release
|Tank 213||Cause: leak from the slop oil line near Tank 213|
Notes: Leaking flange isolated
|C-Dock||Cause: malfunction of automatic sump level indicator gauge results in sump overflow|
Notes: Sump level indicators repaired
|Unicracker Unit||Cause: flange leak|
Notes: Pipeline flange was inspected and repaired
|CLAW 650 Transfer Pipeline||Cause: leaking flange on the CLAW 650 Transfer Pipeline|
Notes: Pipeline taken out of service and repaired
|Tank 36||Cause: Oil was leaking from the bottom of tank 36. source of leak was the drain line, which drains water from the external floating roof, and runs internal the tank. The line developed a leak and was losing oil.|
Notes: Drain line closed, and clean-up initiated.
|Sheet Pile Wall||Cause: DEQ report states, "approximately 3-5 gallons of emulsified slop oil washed through the lifting holes in the sheet pilings that separates the lagoon from the ship channel. According to Diana LeBlanc (Environmental Engineer) with Citgo, the oil was released from the bottom of the lagoon when Morrison surveyors were profiling the bottom of the lagoon."
High winds caused oil to be driven from the surface of the Indian Marais Lagoon, to the sheet pile wall where it escaped into the Calcasieu River.|
Notes: Report states that "Citgo immediately deployed hard and absorbent booms to capture the oil on both sides of the sheet pilings. The water level was pumped down by Citgo and sent to the wastewater treatment area to prevent any additional spillage from the lagoon. ES&H was contracted by Citgo to assist in boom deployment and cleanup. Ms. LeBlanc said that written notification would be forthcoming when the investigation was complete."
|Tank 37||Cause: A top suction valve at pumping tank 37 was cracked open allowing slop oil to move to the ground.|
Notes: BRQ. Vacuum trucks were on the scene following the initial release.
|Tank 36 (EQT0088) and Tank 37 (EQT0089)||Cause: The operator failed to manually close the naphtha valve after the switch to C-4 was made, ultimately causing a roof drain leak on Tank 37, a slop oil tank containing hydrogen sulfide. Thus, Citgo failed to diligently maintain control equipment in proper working order whenever emissions were being made.|
Notes: Immediate corrective actions taken were changing routings of materials into tank 37 and making efforts to identify the source of the light materials that were believed to cause the hydrocarbon release. Vacuum trucks were cleaning up the spill at the time of the police report.
|flange on the slop oil line||Cause: The flange on the slop oil line for the OMB Slop Transfer System separated releasing slop oil to the ground.|
Notes: Vacuum trucks were used to clean up the oil. Stated that they would file a follow up report but none was included in the LDEQ report.
