Accident Classified As: Reportable Quantity

Cause of Problem: Corrosion

A 1/2" diameter previously unidentified area of external corrosion on a 6" sub-surface crude water draw line failed during normal operations.

Discharge Preventable - No

The release was not preventable through procedures, actions, or training because it was a sudden and unforeseeable failure.

Notes/Remedial Actions

Operations immediately isolated the line through the use of existing valves, called out additional personnel to begin containment, clean up, and repair operations and notified the Norco Site Supervisor. Vacuum trucks were utilized to recover all standing liquids. After removal of the liquid hydrocarbon was completed, excavation of visually stained soils was initiated. An external clamp has been installed on the line and the repair area re-coated to prevent additional corrosion. A project has been initiated to relocated this water draw piping above ground.
