Appendix 3.2 : Principal Framework for Planning against Air Pollution

(a) The principal legislation is the Air Pollution Control Ordinance (APCO) and its subsidiary Regulations. The whole of the Territory has been covered by Air Control Zones. The Government aims to achieve the AQOs given in Appendix 3.1 as soon as reasonably practicable. To help achieve the AQOs in areas where they are already exceeded, every planning effort should be made to reduce the air pollution emitters in these areas.

(b) Under the Fuel Restriction Regulations of APCO, only gaseous fuels are permitted in Shatin. For other areas, the fuel sulphur restriction is imposed to limit the content of sulphur to 0.005% by weight for liquid fuels and 1.0% for solid fuels.

(c) The APCO, among other things, provides for the licensing of Specified Processes. These are industries with potential to cause substantial air pollution (Appendix 3.3). A licence issued by the EPD for operation of these processes is required by the Air Pollution Control Ordinance.
