In Chile, the Environmental Agency (SMA) has undertaken an inspection of Antofagasta Terminal Internacional (ATI) to see whether it is complying with regulations for the loading and discharge of mineral concentrates. ATI has introduced a series of measures to suppress dust during these operations, particularly one which involves spraying a mist of water over the vessel hold to prevent contamination entering the atmosphere. The operator has also extended the telescopic chute further out over the vessel to reduce the gap between the conveyor and the hold during loading operations.

ATI has been asked to introduce a series of measures by the SMA to ensure that pollution is kept to an absolute minimum and its success is being monitored by the agency.
