That is, the Applicant should consider alternative construction methods/phasing programmes and alternative modes of operation to minimise the constructional and operational air quality impact respectively.
(iii) Present the background air quality levels in the assessment area for the purpose of evaluating the cumulative constructional and operational air quality impacts. Also present the existing emission data along with the anticipated improved emission data for the Project for comparison purposes.
Identification of ASRs and examination of emission/dispersion characteristics
(iv) Identify and describe representative existing and planned/committed air sensitive receivers (ASRs) that would likely be affected by the project. The Applicant shall select the assessment points of the identified ASRs such that they represent the worst impact point of 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. For phased development, the Applicant should review the development programme to take into consideration the construction stages so as to include occupiers of early phases as ASRs if they may be affected by works at later phases.

(vii) If the Applicant anticipates a significant construction dust impact that will likely cause exceedance of the recommended limits in the TM at the ASRs despite incorporation of the dust control measures stated in (vi) above, a quantitative assessment should be carried out to evaluate the construction dust impact at the identified ASRs based on the emission strength of the emission sources identified in (v) above. The Applicant shall follow (ix) to (xii) below when carrying out the quantitative assessment.
Operational air quality impact
(viii) The Applicant shall calculate the expected air pollutant concentrations at the identified ASRs. Calculations for the expected impact shall be based on an assumed reasonably worst case scenario. The evaluation shall be based on the strength of the emission sources identified in (v) above.

Details of the calculation of the emission rates of air pollutants and a map showing the emission sources and the identified ASRs for input to the modeling shall be presented in the report. The Applicant must ensure consistency between the text description and the model files at every stage of submission. Prior agreement of the general methodology between the Applicant and the Director is advised.

Among the identified parameters, emissions such as toxic air pollutants (including but not limited to dioxins) and odour (if any) shall be included.
(xi) The Applicant shall calculate the cumulative air quality impact at the identified ASRs and compare these results against the criteria set out in section 1 of Annex 4 in the TM. The predicted air quality impacts (both unmitigated and mitigated) shall be presented in the form of summary table and pollution contours, for comparison with relevant air quality standards and examination of the land use implications of these impacts. Plans of suitable scale should be used for presentation of pollution contour for determining buffer distances required. In order to get a full picture of air emissions in particular dioxins from the proposed Project, an inventory figure (in g I-TEQ/year) should be estimated and presented.
Mitigating measures for non-compliance
(xii) The Applicant shall propose remedies and mitigating measures where the predicted air quality impact exceeds the criteria set in section 1 of Annex 4 in the TM. These measures and any constraints on future land use planning shall be agreed with the relevant government departments/authorities and documented. The Applicant shall demonstrate quantitatively that the resultant impacts after incorporation of the proposed mitigating measures will comply with the criteria stipulated in section 1 of Annex 4 in the TM.
