What happened

Pemex recorded three fuel-oil containment losses along the Salina Cruz refinery–marine terminal corridor: an initial leak on 9 June, a second loss on 21 June in a 16-inch pipeline, and another leak in the same section on 7 July. The company suspended and depressurised the affected system, recovered product and repaired the sections, completing the latest work on 8 July. Pemex reported no critical gas concentrations, hazardous conditions, casualties or quantified spill volume, and said containment, recovery and remediation were complete while monitoring continued. Separately, conspicuous flames at the refinery on the night of 21 June were officially attributed to controlled ground-flare operation after a safe shutdown of a steam boiler and catalytic unit; Pemex said that was not an emergency. This record therefore covers the verified pipeline containment-loss cluster, not an unverified 1 June refinery fire or the controlled flaring.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
