Construction Phase
No adverse fugitive dust impact is envisaged with the implementation of dust control measures and adoption of good construction site practices. Minor air quality impacts associated with gaseous emissions of diesel-powered construction plant and equipment are anticipated as only a small number of construction vehicles and plant will be operated in the limited works areas at any one time.

To ensure compliance with the relevant dust criterion at the identified ASRs and implementation of proposed control measures during the construction phase, regular environmental site audits (at a frequency of not less than once per week) are recommended.

Operation Phase
During operation phase, it is confirmed that electric stoves will be used for the kitchens and electrostatic precipitators (ESPs) will also be installed at the exhausts of the kitchens to capture potential particulate emissions.  Proper siting of kitchen exhaust will be considered during the detailed design stage.  As such, potential air quality impacts associated with gaseous emissions from kitchen exhausts are not anticipated. 

Three stacks were identified to be in operation within the study area and were all operated by restaurants.  They are all located at least 30m above ground.  It was anticipated that these operating stacks were operating with towngas or ULSD or alternative fuel types in which emissions are low and comply with the requirements in the Air Pollution Control (Fuel Restriction) Regulation and its amendment of 2008.  With respect to the height of emission points, the presence of high-rise buildings located between the Project site boundary and the operating stacks and the recent 5 year NO2 and SO2 monitoring data obtained from the nearby EPD AQMS, no adverse air quality impacts are anticipated for the Project.

The design of the Project encourages visitors to get to the Site via footbridge and pedestrian crossings, therefore, traffic flow induced by operations of the Project (eg tourist buses and private cars) is anticipated to be small as compared to the existing traffic flow on nearby roads.  No adverse traffic emission impact during the operation phase of the Project is therefore expected.
