Air Quality Impact. Fugitive dust impact from construction works activities can be minimized with proper implementation of mitigation measures. The population protected by the mitigation measures includes all ASRs within 500m from Project Boundary, which include residents, place for worship, offices, parks and elderly centre along Kam Tin Road and Xxx Xxx Road. Cumulative air quality impact arising from the vehicular emissions at representative ASRs would comply with Air Quality Objectives.
Air Quality Impact. I. The Assessment shall make reference to the prevailing Air Quality Objectives (AQOs), relevant technical memorandum and other relevant guidelines in proposing the methodology and criteria.
Air Quality Impact. Dust mitigation measures stipulated in the Air Pollution Control (Construction Dust) Regulation should be implemented to minimize fugitive dust emissions from the works area during the construction phase. Relevant control measures are listed below : • Use of regular watering to reduce dust emissions from exposed site surfaces and unpaved road, with complete coverage, particularly during dry weather; • Use of frequent watering for particularly dusty static construction areas; • Tarpaulin covering of all dusty vehicle loads transported to and from site; and • Water construction vehicles’ wheel and body before exiting the construction site.
Air Quality Impact. The Consultants shall follow the criteria and guidelines for evaluating and assessing air quality impact as stated in Section 1 of Annex 4 and Annex 12 of the TM respectively. The assessment area for the air quality impact assessment shall generally be defined by a distance of 500m from the boundary of the Project works sites, yet it may be extended depending on the circumstances and the scale of the Project. The Consultants shall assess the air pollution concentrations with reference to relevant sections of the Guidelines for Local-Scale Air Quality Assessment Using Models (xxxx://xxx.xxx.xxx.xx/epd/english/environmentinhk/air/guide_ref/guide_aqa_model.html) or other methodology as agreed by the Director of Environmental Protection. The air quality impact assessment shall include the following : Background and Analysis of Activities Provide background information relating to air quality issues relevant to the Project, e.g. description of the types of activities during operation stage of the Project such as emission of odour from the proposed food waste pre-treatment facilities; Give an account, where appropriate, of the consideration/measures that have been taken into consideration in the planning of the Project to xxxxx the air pollution impact. The Consultants shall consider alternative modes of operation to minimise the operational air quality impact; Present the background air quality levels in the assessment area for the purpose of evaluating the cumulative operational air quality impacts. Identification of Air Sensitive Receivers (ASRs) and Examination of Emission/Dispersion Characteristics; Identify and describe representative existing and planned/committed ASRs that would likely be affected by the Project, including those earmarked on the relevant Outline Zoning Plans, Development Permission Area Plans, Outline Development Plans and Layout Plans. The Consultants shall select the assessment points of the identified ASRs such that they represent the worst impact point on these ASRs. A map showing the location and a description including the name of the buildings, their uses and height of the selected assessment points shall be given. The separation distances of these ASRs from the nearest emission sources should also be given; Provide an exhaustive list of air pollutant emission sources, including any nearby emission sources which are likely to have impact on the Project. Examples of operational stage emission sources include odour emissions from th...
Air Quality Impact. 11.5.1 The Project site area covers south apron, runway and a narrow strip of north apron of the former Kai Tak Airport, however, the demolition works will only be limited to those areas with remaining existing structures / buildings and abandoned facilities of the former Kai Tak Airport. With the implementation of the requirements stipulated in the Air Pollution Control (Construction Dust) Regulation during demolition works, transportation & unloading of excavated contaminated soil and mixing process in solidification, adverse dust impact would not be expected. No cumulative dust impacts from the concurrent projects in the proximity of the study area would be anticipated.
Air Quality Impact. All working plants and vessels on site should be regularly inspected and properly maintained to avoid dark smoke emission. All vehicles should be washed to remove any dusty materials before leaving the site. Haul roads should be sufficiently dampened to minimize fugitive dust generation. Wheel washing facilities should be properly maintained and reviewed to ensure properly functioning. Temporary exposed slopes and open stockpiles should be properly covered. Enclosure should be erected for cement debagging, batching and mixing operations. Water spraying should be provided to suppress fugitive dust for any dusty construction activity.
Air Quality Impact. 3.4 The Consultants shall follow the criteria and guidelines for evaluating and assessing air quality impact as stated in Section 1 of Annex 4 and Annex 12 of the TM respectively.
Air Quality Impact. 9.1 Introduction The Contractor should follow the Air Pollution Control (Construction Dust) Regulation to implement dust mitigation measures during construction to minimise the dust impact to the nearby air sensitive receivers and to ensure the effectiveness of the implementation of dust mitigation measures recommended in the EIA report. It is recommended that regular site inspections should be carried out by the ET to ensure that the recommended mitigation measures are carried out by the Contractor. Special attention should be paid to the enforcement of dust control measures during construction process. The ET should consider the programme and site for construction works in determining the location to carry out the site inspection.
Air Quality Impact. 4.13 The Consultants shall assess the air quality impacts to all the air sensitive receivers (ASRs) (including existing, committed and planned uses) in areas in which developments are proposed under the Main Study and in the vicinity of the proposed developments during operation phase. The assessment shall include the following tasks:
Air Quality Impact. 4.2.1.1 With the implementation of dust suppression measures stipulated in Air Pollution Control (Construction Dust) Regulation, good site practice and proposed mitigation measures, no adverse dust and odour impact arisen from the construction works would be expected at the ASRs in the vicinity of the site. No air quality monitoring is therefore considered necessary. Weekly site audit is recommended to be conducted during construction phase in order to ensure the proposed mitigation measures are implemented in an appropriate manner and are effective.
