|LDEQ Incident Number
|Point Source(s)||Notes||Amount of Release|
|Unit Main Air Blower, RCCU Flare (EPN 8-84)||Cause: RCCU experienced instrument protective function shutdown activation of the unit's MAB just prior to the release. There was low Oil pressure detected and therefore the MAB shut down automatically. The RCCU is dependant on the MAB for functioning|
Notes: remedial actions: all units were secured and steps were taken to minimize emissions, also attempting to implement some mechanical improvement
|Coker, HCU, West Op Ground flares||Cause: power failures due to weather (Tropical Storm Cindy) caused various releases from Motiva sources; led to total loss of electrical instrument air compressors and the loss of several steam Boilers that caused the shutdown of the HCU and RCCU process units. A voltage sag caused the Coker processor to shut down which resulted in a flaring event|
Notes: Motiva claims that this was not preventable because of the unforeseeable weather conditions.
|RCCU unit CO heater||Cause: RCCU unit discovered several tube leaks in the CO heater, necessitating a controlled shutdown of the heater and RCCU and the diversion of all regenerator flue gas to the atmosphere and away from the flue gas scrubber to mitigate safety concern.
Even went on over 5 days--RQs exceeded.
No DEQ report in this file--follow-up only.|
Notes: 76 tubes that were in poor condition replaced in the CO heater.
|FLARE: West Ops Ground Flare [EPN 9-84]||Cause: Refinery letter states that "Shell Chemical's GO-1 Process unit experienced an upset when the feed to the unit furnaces was unexpectantly shut off. This process led to flaring at the Motiva's West Operations Ground Flare." SHARED INCIDENT WITH SHELL CHEMICAL PLANT.
Separate report will be filed for Shell LP Norco Chemical Plant-East Site will be submitted. FLARE.|
Notes: BRQ. Follow-up reports states that no reportable quantities or permit limits were exceeded. No Information Given regarding remedial actions. Refinery letter states that this information will be included in the Shell Chemical incident report.
