Regulation
A single file per station
A Mexican fuel station answers to half a dozen authorities, each with its own package, format and calendar. The alternative: a single file the operator maintains, from which each authority reads what it needs.

A fuel station in Mexico answers, at the same time, to the tax authority, the energy regulator, the safety and environment agency, consumer protection, customs, and state and municipal authorities. Each asks for its own package of documents, in its own format, on its own calendar.
The question more and more operators are asking is simple: why not a single file?
The principle: submit once
The European Union applies the once-only principle: a company should not have to give the government the same information twice. Applied to fuels, it means a single file per station, maintained by the operator, from which each authority reads what falls within its remit.
What it would contain
| Block | Examples |
|---|---|
| Permits | Retail or distribution permit, import |
| Safety and environment | Risk management system, vapour recovery (in mandatory zones), hazardous waste |
| Tax | Volumetric control, certificates, laboratory reports, reconciliation with invoices |
| Transport | Carta Porte (bill of lading), vehicle traceability |
| Consumer | Dispenser verification |
| Local | Land use, licences, civil protection |
What each party gains
- The operator: one place, with expiry dates and alerts, and the package ready for every inspection.
- The authority: consistent, up-to-date information, without asking for the same thing several times.
- The inspector and the laboratory: a complete history of the facility.
- The system as a whole: less regulatory latency, less room for irregularities and more competitiveness.
It can start today
There is no need to wait for a federal reform. The single file can start as the operator’s own tool: a digital file organised by authority, with timestamping and reliable metering data. If a station group adopts it and a state government accepts it for its procedures, it becomes the pilot for something that can scale later.
International experience helps. In Germany, for example, the calibration law (Eichrecht) requires metering data at EV chargers to be cryptographically signed, so that anyone can verify it afterwards. It is the same principle the litre of fuel needs: data that cannot be altered and can be audited.
