Accident Classified As: No Information Given
Cause of Problem: Equipment Failure
On 9/9/14, a refinery operator discovered crude oil overflowing from TK-105, a soft water tank. The oil was accumulated on the ground in the area of TK-105 and south of the tank under the nearby pipe rack. The oil, some of it floating on standing water, was covering an area of approximately 1720 square feet. The release occurred when the soft water pump at TK-105 failed and crude oil back up the soft water injection line and into the soft water tank. A check valve in this line failed open allowing the oil to reach the tank.
Discharge Preventable - No Information Given
Report does not indicate if preventable or if there will be any followup investigation.
Notes/Remedial Actions
The failed check valve has been replaced with a more reliable type of check valve. Calcasieu Refining also installed an alarm to alert operators when the soft water pump fails. Contaminated soil was removed from the area and Micro-Blaze (microbial agents that degrades hydrocarbons) was applied to the area. Clean soil was moved in to replace removed soil.
