Air Quality Impact – Construction Phase |
|||||||||
|
3.6.1 |
2.2 |
General Practices for Dust Control It is recommended that the following dust mitigation measures are implemented to maintain dust emissions at acceptable levels during the construction phase: ● Any dusty activities should be regularly sprayed with water to maintain damp conditions of the works area. ● Any dusty materials should be covered with tarpaulin or similar material during transportation. ● Any dusty materials stockpiles should be either (i) covered entirely by impervious sheeting; or (ii) sprayed with water.
Best Practices for Dust Control It is recommended that the relevant best practices for dust control as stipulated in the Air Pollution Control (Construction Dust) Regulation should also be adopted to further reduce the construction dust impacts of the Project. These best practices include:
Good Site Management ● Good site management is important to help reduce potential air quality impact down to an acceptable level. As a general guide, the Contractor should maintain high standard of housekeeping to prevent emission of fugitive dust. Loading, unloading, handling and storage of raw materials, wastes or by-products should be carried out in a manner so as to minimise the release of visible dust emissions. Any piles of materials accumulated on or around the work areas should be cleaned up regularly. Cleaning, repair and maintenance of all plant facilities within the work areas should be carried out in a manner minimising generation of fugitive dust emissions. The material should be handled properly to prevent fugitive dust emission before cleaning.
Loading, Unloading or Transfer of Dusty Materials ● All dusty materials should be sprayed with water immediately prior to any loading or transfer operation so as to keep the dusty material wet.
Debris Handling ● Any debris should be covered entirely by impervious sheeting or stored in a debris collection area sheltered on the top and the three sides. ● Before debris is dumped into a chute, water should be sprayed so that it remains wet when it is dumped.
Transportation of Dusty Materials ● Vehicle used for transporting dusty materials/spoils should be covered with tarpaulin or similar material. The cover should extend over the edges of the sides and tailboards.
Wheel washing ● Vehicle wheel washing facilities should be provided at each project site exit. Immediately before leaving the project site, every vehicle should be washed to remove any dusty materials from its body and wheels.
Use of vehicles ● Immediately before leaving the project site, every vehicle should be washed to remove any dusty materials from its body and wheels. ● Where a vehicle leaving the project site is carrying a load of dusty materials, the load should be covered entirely by clean impervious sheeting to ensure that the dusty materials do not leak from the vehicle.
Site hoarding ● Where a site boundary adjoins a road, street, service lane or other area accessible to the public, hoarding of not less than 2.4m high from ground level should be provided along the entire length of that portion of the site boundary except for a site entrance or exit.
During excavation works, the following mitigation measures are recommended in order to contain potential odour from excavated sediment: ● all malodorous excavated material should be placed as far as possible from any ASRs; ● the stockpiled malodorous materials should be removed from site as soon as possible; and ● the stockpiled malodorous materials should be covered entirely by plastic tarpaulin sheets. |

Inert and Non-inert C&D Materials In order to minimise impacts resulting from collection and transportation of inert C&D materials for off-site disposal, the inert C&D materials should be reused on-site as fill material as far as practicable. In addition, inert C&D materials generated from excavation works could be reused as fill materials in local projects that require public fill for reclamation. The surplus inert C&D materials will be disposed of at the Government’s PFRFs for beneficial use by other projects in Hong Kong. The C&D materials generated from general site clearance should be sorted on site to segregate any inert materials for reuse or disposal of at PFRFs whereas the non-inert materials will be disposed of at the designated landfill site. In order to monitor the disposal of inert and non-inert C&D materials at respectively PFRFs and the designated landfill site, and to control fly-tipping, it is recommended that the Contractor should follow the DEVB Technical Circular (Works) No. 6/2010 for Trip Ticket System for Disposal of Construction & Demolition Materials issued by Development Bureau. In addition, it is also recommended that the Contractor should prepare and implement a Waste Management Plan detailing their various waste arising and waste management practices in accordance with the relevant requirements of the ETWB Technical Circular (Works) No. 19/2005 Environmental Management on Construction Site |
