MEXICO CITY, MEXICO (By Fidencio Casillas, Editores Latin Petroleum, 4.Sep.2026, Words: 293) — Federal environmental authorities and the Nuevo León state government, with the participation of state-owned Petróleos Mexicanos (PEMEX), agreed to strengthen inspection, monitoring, and evaluation efforts following reports of unusual odors in the Monterrey metropolitan area.

The goal is to determine the source of the odors and, based on the findings, implement appropriate measures.

After a technical meeting on 3 Sep. 2026 and a tour of the Cadereyta refinery facilities, representatives from the participating institutions reviewed the work completed to date and agreed to strengthen coordination, information sharing, and joint actions, the Mexico City-company said on 4 Sep. 2026 in an official statement.

ASEA inspection

As part of these efforts, the Agency for Safety, Energy and the Environment (ASEA) reported on the inspection visit conducted at the Cadereyta refinery on 31 Aug. 2026, the results of which are currently being evaluated.

INECC assessment

Likewise, the National Institute of Ecology and Climate Change (INECC), in coordination with the government of the state of Nuevo León, will conduct an assessment in the previously identified areas of the Monterrey metropolitan area by monitoring pollutants to identify potential sources of emissions.

With the support of PEMEX, it will also continue monitoring in the area surrounding the Cadereyta refinery.

Semarnat assistance

For its part, the Ministry of Environment and Natural Resources (Semarnat) will provide technical assistance for the review and validation of the results of these assessments.

Based on these results, appropriate measures will be defined to improve air quality in the Monterrey metropolitan area, for the benefit of its residents, PEMEX said.
