Public-Use Fuel Service Stations

Fuel Inflow-Outflow Systems

This is the integrated system for monitoring inflows and outflows at Public-Use fuel service stations to ensure financial interests and protect consumers.
All public fuel stations must register in the Registry for monitoring inflows and outflows, in accordance with Joint Ministerial Decision No. A.1151/15.10.2024 (Government Gazette B’ 5991).

 

Entities required to register include:

  1. Holders of operating licenses for public-use liquid fuel stations, LPG stations, or mixed liquid fuel and LPG stations
  2. Heating oil sellers
  3. Installers of inflow-outflow monitoring systems
  4. Accredited tank calibration service providers
