The most important issues impacting on air quality are dust, atmospheric emissions from tenant factories, and ship emissions. Ships are prohibited from producing smoke within the port confines, although reasonable amounts are tolerated during start-up of engines and while getting under way.
Ports where dust producing cargoes are handled must include dust management procedures in their environmental management systems.
These procedures could include some or all of the following:
- Covering of dust-producing materials during transport
- Covering dust sources being stored within the port confines
- Dust suppression by watering down
- Paving of loading areas
- Avoidance of loading or off-loading of dust producing cargoes during windy conditions
