|plant pipeway||Cause: Release of 121.8 gallons of Heavy Cycle Gas Oil (HCGO) resulted when a leak developed in a previously installed clamp in a plant pipeway. The release point was not subject to permit.
Inspection was conducted by the Louisiana Department of Environmental Quality (LDEQ) on 8/24/14.|
Notes: Oil was contained on site, recovered using vacuum trucks and reprocessed in the refinery's recovered oil system. A drip pan and absorbent pads were deployed to contain and absorb the leak. The leak was isolated and stopped and the line is currently being prepared for maintenance. The High-cycle gas oil was contained/recovered on site. Residual oil staining remaining on the vegetation and ground surface was excavated and removed until oil was no longer visible. Oil in contact with the ground was confined to the surface with no impact below a couple of inches. All oil-stained soils, PPE, and other contaminated materials were properly containerized for disposal. Bioremediation bagasse pads were deployed to treat any remaining material. The clamp and leaking section of pipe will be replaced with a new pipe stool.
