2010-10-25		FLARE - FCCU flare
Cause: "Loss of power in Complex II caused operating and utility units to shutdown. This even resulted in flaring from the FCCU flare" Due to the loss of power, the complex II steam producers shut down, therefore the flare steam assist was lost. This resulted in smoking flares. This released the following chemicals: SO2, H2S, NOx, VOC, Hexane, and 1,3 Butadiene. FLARE.

Followup: No

Notes: A power feed was connected from Complex I to Complex II, and boilers were restarted to produce steam to assist the FCCU flare, and shutdown procedures was continued. No LDEQ report. Refinery Letter only.		32.0 pounds
