Accident Classified As: Reportable Quantity

Cause of Problem: Piping or Tubing

Piping leak at the B-Topper Unit. Due to the temperature of the naphtha steam and the elevation of the line relative to the ground, the leaking material evaporated and did not reach the ground.

Discharge Preventable - No Information Given

The line is periodically inspected for metal loss and the corrosion caused leak in the line was not expected.

Notes/Remedial Actions

Original letter states that the phone call to report this incident occurred on December 24, 2005, while the follow up letter states the incident occurred on December 23, 2005 at 23:45 hours. Claims all pollutants were released as liquids but vaporized before reaching the ground. Heavy naphtha release was below reportable quantities. The pumparound piping from which the leak was coming was shutdown and isolated for repair when the Unit was shutdown. A Failure Analysis was scheduled for this incident. Second attached letter states that upon re-start up of the B-Unit Topper on December 29, H2S and SO2 were possibly released but below reportable quantities
