Major developments include constructing, repairing or altering new runways, a new building or road within the airport. A major development plan must comply with this Standard. An airport-lessee company must monitor the levels of pollution present in air, water or soil at the airport and the level of noise generated at the airport.

2000年8月10日 · Provides guidance on the siting and construction of new buildings against aircraft noise intrusion and on the acoustical adequacy of existing buildings in areas near aerodromes. The assessment of potential aircraft noise exposure at a given site is based on the Australian Noise Exposure forecast (ANEF) system.

Gives guidelines for determining- (a) whether the extent of aircraft noise intrusion makes building sites 'acceptable', 'unacceptable' or 'conditionally acceptable' for the types of activity to be, or being, undertaken (Clause 2.3); (b) for 'conditionally acceptable' sites, the extent of noise reduction required to provide acceptable noise level...
