Accident Classified As: Reportable Quantity

Cause of Problem: Process Upset

Wastewater pump discharge was intermittently backing into caustic scrubber recirculation lines as a result of differential pressure.

Discharge Preventable - No

The refinery states that all applicable standard operating procedures were followed.

Notes/Remedial Actions

A skillet blind was inserted in the line near the suspected leaking valve to Incinerator B to protect against potential leak. The applicable pump-down procedure was modified/improved. A check valve was installed in the affected level control blowdown line to prevent liquid backup. The refinery submitted and received a revised permit for the affected sources, which it says better accounts for hourly maximum emission rates, on August 11, 2006. LABB's file only contains the letter dated 11/7/2006 and no LDEQ report, SPOC report, etc.
