The total number of NSRs projected to be affected by the new airport is exceptionally small for a major international airport, primarily because such a large proportion of the affected areas are over open water.
Air Quality
· The creation of dust during the airport site preparation project will be unavoidable, the master plan notes. About 178 million cubic metres of sand and rock fill will be moved to form the airport reclamation. About 184 million cubic metres of mud will be removed from existing sites and replaced with the fill.
Fortunately, the remote location of the site and the prevailing wind patterns will limit the potential impacts at receptors on Lantau Island,
Based on computer modelling results, the greatest potential impacts are expected in the initial construction period and when the wind is from the north over Chek Lap Kok. Under these "worst case" conditions, the dust plume created by the blasting operations could contribute to increased dust levels along the coastline of North Lantau, but only for several minutes during each occurrence.
Upon completion of the new airport, the two principal sources of air emissions associated with the new airport will bo aircraft and motor vehicles.
The results of computer modelling indicate that under "worst case" meteorological conditions, contributions to pollution levels on North Lantau from on-airport activities are projected to be well within the established Air Quality Objectives.
