On July 17, 2025, the “Agreement for the Control and Monitoring of Air Pollutant Emissions to Be Observed by Regulated Parties at Service Stations Specifically Intended for the Retail Sale of Gasoline and/or Diesel” was published in the Federal Official Gazette by the National Agency for Industrial Safety and Environmental Protection of the Hydrocarbons Sector (ASEA).
This Agreement came into force today, July 18, 2025, and establishes new obligations for service stations aimed at preventing and reducing emissions of air pollutants.
Key obligations:
- Sampling of petroleum products (gasoline and/or diesel) stored in tanks, using either manual or automatic methods in accordance with ASTM D4057 or D4177 standards.
- Submission of reports to ASEA:
- Every three months, if no additional control mechanisms are in place.
- Every six months, if the station must implement controls such as volumetric systems or leak detection devices.
- Quality testing and compliance with technical specifications set forth in Annexes I through IV of the Agreement.
- Retention of reports and documentation at each service station for a minimum period of one year.
- Granting access and cooperation to the Agency during inspections and verification visits.
Report submission:
Until the Electronic Filing Office becomes available, reports must be submitted in physical format at ASEA’s regulated parties’ service area, within 10 calendar days after the end of each applicable quarter or semester.
When must the first report be submitted?
Although the Agreement does not expressly set a deadline for the first report, it is understood that the reporting obligations follow the regular calendar periods from the date the Agreement enters into force. Accordingly:
- Parties required to submit quarterly reports must deliver their first report no later than October 10, 2025, covering the third quarter of the year.
- Those authorized to submit semiannual reports must deliver their first report no later than January 10, 2026, covering the second half of the year.
Recommendations:
Service stations and regulated companies should immediately review their sampling, documentation, and emission control procedures, and verify that testing is carried out by accredited laboratories in accordance with the Quality Infrastructure Law. Timely implementation of these measures is essential to avoid potential penalties.
