Notes

The facility has experienced two major incidents in recent months (fire in February 2025 shutting down the 141,000 bpd CDU, and a fatal gas leak in May 2025). These unplanned shutdowns and the need for repairs indicate the refinery is currently non-operational and dealing with significant damage/safety issues rather than routine maintenance.
