88564 2006-06-13 | flare #2 | Cause: piece of instrument air tubing failed causing a bypass control valve around a steam generator to close. Flow through the intermediate cycle gas oil circuit stopped, causing de-ethanizer tower to slump, increasing concentration of light material in the de-butanizer tower feed, increased pressure, causing flaring event Followup: No Notes: "unit charge rate and riser temperature were reduced immediately following the loss of heat medium into the de-ethanizer reboiler to minimize the loading to the debutanizer tower. The bypass around 2PDC-142 was opened to re-establish flow to the de-ethanizer reboiler." | Sulfur Dioxide: 1,756.0 pounds Hydrogen Sulfide: 4.7 pounds Volatile Organic Compounds (VOCs): 124.4 pounds Particulate Matter 10: 11.4 pounds Carbon Monoxide: 328.6 pounds Nitrous Oxide: 60.4 pounds |

134255 2011-09-29 | No Information Given | Cause: A pinhole leak in line resulted in an oil release. Followup: No Notes: No information given for remedial action. Motiva states that mostly water was leaked and a RQ exceedence was not reached. LDEQ only no Refinery Letter included. | |
138520 2012-04-03 | Isolation valve | Cause: While working on the Alky splitter tower reflux pump, the technician loosened screws from a mounting plate connected to a pressure gauge. The tubing connection located upstream of the isolation valve failed and released hydrocarbon. The initial report from the facility stated that 178 pounds of propylene were released when a 1/2 inch tubing broke a reflux pump, but the release was later determined to be below reportable quantity. Followup: No Notes: No information given about remedial actions taken. The refinery letter stated that the incident was not reportable, and no injuries, fatalities, or road closures were associated with this incident. | Propylene: 88.6 pounds |
No LDEQ Reported 2013-11-24 | None Reported | Cause: On November 24, 2013, Motiva reported a small fire that occured at Motiva's Fluidized Catalytic Cracking Unit in the Main Fractionator Column. After the fire was put out, they discovered a leak on the Top Reflux draw line. They believe this leak caused the fire. Incident duration was approximately 4h. Followup: No Notes: After a safety plan was developed, the Top Reflux line was isolated. No injuries occurred. The incident was initially reported as potential Reportable Quantity exceedance. However, during the event, no release exceeding an RQ occurred. | |
151418 2013-10-06 | H-Oil F-202 reactor | Cause: There was a release of hydrogen sulfide on October 6, 2013 due to damaged tubing in the F-202 reactor in the H-Oil unit.
Initially, a potential hydrogen sulfide release was reported in exceedance of the 100 pound reportable quantity, but after further evaluation, the total hydrogen sulfide emissions were below reportable quantity. Followup: No Notes: | |
158268 2014-08-24 | 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. Followup: No 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. | Heavy Cycle Gas Oil: 121.8 gallons |
