The Consultants recommend that a noise exposure of 25 NEF (shown as the lighter shading in the figure) be used as the guideline to establish a threshold of unacceptable noise impact for residential land uses. This is a conservative approach but Consultants' opinion is that it is appropriate both to the character of life in Hong Kong and to the period in which the airport will become operational.
Little data is available on the existing marine habitat for use in estimating the potential effects of airport construc- tion on the marine environment, but the available data indicates that no significant major impact on the envi- ronment can be expected. The Consultants have outlined a recommended programme for data collection and analysis to determine if there are any potential adverse impacts and to identify mitigation measures needed during facility design and construction to ensure protec- tion of the environment.

Relocation of the resident population on Chek Lap Kok Island will be necessary. This involves about 300 residents; a small number in comparison to similar projects of this magnitude. A small number of residents (up to 430) on the San Tau headland may also have to be relocated, subject to final Master Planning of facilities.
