Overview
- A visible oily stain was detected on June 2 in the waters of Bahía de Manzanillo, triggering an official response from federal and state agencies.
- The Secretaría de Marina, through its marine-environment unit PROMAM, filed a formal denuncia requesting investigators determine the origin of the substance.
- Joint inspections by SEMARNAT, PROFEPA, ASEA, ASIPONA Manzanillo, Protección Civil and Pemex found no operational anomalies or leaks that link Pemex infrastructure to the stain.
- Pemex is supplying containment booms, oleophilic cordons and absorbent materials while ASIPONA Manzanillo maintains permanent maritime surveillance and continuous environmental monitoring.
- Investigations remain open with no responsibilities assigned yet, and regulators say forensic analysis and ongoing patrols will guide potential enforcement and assess ecological or port impacts.
