Accident Classified As: No Information Given

Cause of Problem: Piping or Tubing

Discharge piping on the sanitary system sump pumps serving the RCCU and DU-5 units leaked sewage due to plugged pipe. Material drained to a nearby stormwater sewer and was discharged into the refinery wastewater treatment system bypassing normal sewage treatment routing. See also incidents 96492 and 97505, reports of the same date.

Discharge Preventable - No Information Given

Notes/Remedial Actions

Vacuum truck was called out to pick up material and prevent additional leakage to the wastewater system. Operations blew line free of plug, reestablishing flow. Motiva will make permanent repairs once evaluation of lines is complete. Routine emptying of the sanitary sump via vacuum truck is being conducted until repairs to the discharge line are completed. The material was routed directly to the refinery wastewater treatment system and received full treatment through this system prior to discharge.
