Department of Petroleum Resources, DPR Gombe field office has sealed off four filling stations in some parts of the state.
The retail outlets were sealed off during routine monitoring operation carried out by the Department across the state.
Two of the retail outlets along Kaltungo-Billiri axis were sealed off for operating without a licence while the remaining two from Nafada axis were sealed for diversion of product.
Similarly, the monitoring team had frowned at the absence of safety measures in most of the retail outlets along the Dukku axis of the state.
In one of the filling stations, two people were caught using a generating machine to transfer fuel from one underground tank to the other without authorisation.
The monitoring team immediately ordered the stoppage of the illegal act and also threatened to seal off the filling station.
The Head Health, Safety and Environment Unit of the DPR Gombe field office, Mr Eteme Osu expressed dismay over non-compliance with safety standard in most of the filling stations across the country.
