Point Source(s) | Notes | Amount of Release |
92480 2006-12-08 | flare | Cause: Nitrogen oxide resulting from flaring off the H-Oil PSA skid
brief Motiva letter only in this file, no LDEQ report
RQ not exceeded Followup: No Notes: no information given | |
88564 2006-06-13 | flare #2 | Cause: piece of instrument air tubing failed causing a bypass control valve around a steam generator to close. Flow through the intermediate cycle gas oil circuit stopped, causing de-ethanizer tower to slump, increasing concentration of light material in the de-butanizer tower feed, increased pressure, causing flaring event Followup: No Notes: "unit charge rate and riser temperature were reduced immediately following the loss of heat medium into the de-ethanizer reboiler to minimize the loading to the debutanizer tower. The bypass around 2PDC-142 was opened to re-establish flow to the de-ethanizer reboiler." | 60.4 pounds |
100801 2007-11-06 | Steam Boiler EPN 31F-810 Tail Gas Treatment Unit No. 4 Incinerator Stack EPN 78H-101 VPS-2 Atmospheric Tower Feed Heater EPN 83H-101 | Cause: The seal on a diesel circulation pump on VPS-2 (a crude distillation unit) failed as a reslut of a suspected bearing problem. This seal failure caused the release of approximately 434 bbls of untreated (sour) diesel, which ignited, resulting in a fire. Followup: Yes Notes: Motiva has slowed down production throughout the refinery until investigations are complete. Inspected, repaired, and rebuilt the pump as necessary. W/r/t pump seal failure, rotating equipmt and other personnel will complete the investigation and implement necessary changes to monitoring, inspection, and maintenance procedures | 5.0 pounds |
117554 2009-08-22 | FCCU wet gas scrubber stack | Cause: NOX emissions in excess of maximum emission rate during start-up of Fluid catalytic Cracking Unit Wet Gas Scrubber Stack after a subsequent trip on 8/17/09--related to use of platinum promoter in addition to catalyst to maintain temperatures inside the FCCU regenerator within equipment metallurgical limits.
Did not exceed reportable quantities. Followup: Yes Notes: no info given |
