Upon start up of RCCU, it is suspected the RCCU flare pilot was unlit causing release to air of Ethylene, Propylene, 1,3=Butadiene, VOC, Flammable Gas, HRVOC. HEAVY FLARING ALSO OCCURRED AT SHELL CHEMICAL LP but will be included in a separate report (GO-1 flare). Follow-up report states that "Motiva WAS NOT ABLE TO DETERMINE THE ULTIMATE CAUSE of the loss of the pilot flame, but that gas pressure being set above the design pressure or severe weather conditions may have contributed to the loss of pilot flame. FLARE.
RQ. Reportable quantities were exceeded during this incident. "All released materials were dispersed naturally in the atmosphere from the RCCU flare stack." Release was stopped by the re-lighting of the flare.
