Notes/Remedial Actions

Remedial actions: Vacuum trucks were deployed in attempt to capture the oil in the RCCU drainage system. Feed was immediately diverted from the unit. Flow into the main fractionator column was minimized while isolations were being made to the slurry circulation system. VSERT was activated to make positive isolation of the leak. Concerning recurrence prevention, Motiva's incident investigations group is investigation the incident and recommendations will be addressed.
