Construction Phase
The following key mitigation measures will be implemented to reduce the dust and gasesous emission as much as possible:

	Water spaying on haul roads and dusty areas for at least eight times a day;
	Covering the stockpile areas of at least 70% area with tarpaulin sheet or impervious sheet;
	Covering of dusty materials/spoils on trucks by impervious sheets;
	Controlling the dropping height of fill materials;
	Covering or storing all debris and materials in a sheltered debris collection area;
	Storing dredged sediment in a separate enclosed tank; and
	Providing wheel washing facility at each exit of the works site.

Good site practices such as regular maintenance and checking of the diesel powered mechanical equipment will be adopted to avoid any black smoke emissions and to minimize gaseous emissions.

Dredged sediment placed on truck or marine vessel for disposal should be properly covered during transportation to minimize the potential odour. In the event that dredging material are found to be odorous, the odorous dredged sediment should be placed as far away from the identified ASRs as practically possible and should be removed off-site as soon as practicable to avoid any potential odour nuisance arising .

Operation Phase
In order to minimize the potential odour emissions, if any, the dredged sediment placed on truck or marine vessel for disposal should be properly covered as far as practicable during transportation. In the event that dredging material are found to be odorous, the odorous dredged sediment should be placed as far away from the identified ASRs as practically possible and should be removed off-site as soon as practicable to avoid any potential odour nuisance.
