3. Air Quality

3.1 Introduction

3.1.1 The EIA Report concluded that no significant impacts would arise from the construction phase of the Project. With proper implementation of good site practices stipulated in the Air Pollution Control (Construction Dust) Regulation and with the adoption of construction machineries and non-road vehicles meeting the prescribed emission standards and requirements specified in the Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation, no adverse air quality impacts associated with the proposed drainage improvement works is anticipated.

3.1.2 In this section, the requirements for the monitoring and audit of air quality impacts during the construction phase of the drainage improvement works are presented.

3.2 EM&A Requirements during Construction Phase

Air Sensitive Receivers

3.2.1 Air Sensitive Receivers (ASRs) within the 500 m Study Areas at Sung Shan New Village, Tai Wo, Lin Fa Tei and Ha Che have been identified according to the criteria set out in Annex 12 of the EIAO-TM, observations from site visits and review of the latest approved Outline Zoning Plans (OZPs) and information available in the Statutory Planning Portal of the Town Planning Board. The identified air sensitive receivers are shown in Figures 3.1 to 3.5.

Construction Dust Monitoring

3.2.2 No specific construction dust monitoring is recommended given the proper implementation of the dust control measures as required under the Air Pollution Control (Construction Dust) Regulation and the recommended mitigation measures.

Mitigation Measures

3.2.3 The Contractor shall be responsible for the design and implementation of the mitigation measures as recommended in Appendix 1, Table A1-1.
