Accident Classified As: Reportable Quantity
Cause of Problem: Under Investigation
The release occurred eastern perimeter of the Unit 222 Saturates Gas Unit. Discharge discovered during an inspection of the stormwater sewer system. Excavation in the area determined the source of oil to be a leaking oily water sewer (OWS) junction box.
Discharge Preventable - Under Investigation
Marathon stated that the root cause of the release is under investigation, therefore, it could not be determined at that time whether the discharge was preventable.
Notes/Remedial Actions
The leaking OWS junction box was isolated on July 31, 2012. Excavation activities to remove contaminated soil into 55-gallon drums and roll-off boxes were ongoing during time of the report. The excavated material was to be tested and properly disposed of at a permitted facility. Marathon claimed that they would collect soil samples under completion of the removal of contaminated soil and those samples would be analyzed to verify that the soil meets the allowable levels set forth in LDEQs Risk Evaluation/Corrective Action Program (RECAP) document. Any subsequent recommendations were to be implemented to prevent reoccurrence of the incident upon completion of the investigation. LABB was unable to find the LDEQ verbal report or original SPOC report. They claimed the release was less than 10 barrels so we estimated the release to be 9 barrels, which is 378 gallons.
