Impact Assessment

3.3.1.4. The air quality impact assessment shall include the following:

Background and analysis of activities

(i) Provide background information relating to air quality issues relevant to the project, e.g. description of the types of activities during construction stage of the project such as reclamation that will likely give rise to dust emissions and those activities during operation stage of the project such as fuel combustion that will give off gaseous emissions.

(ii) Give an account, where appropriate, of the consideration/measures that had been taken into consideration in the planning of the project to abate the air pollution impact. 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. For example, include use of marine access routes for transportation of construction materials to avoid dust impact on ASRs due to haul road transport during construction.

(iii) Present the background air quality levels in the assessment area for the purpose of evaluating the cumulative constructional and operational air quality impacts.

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.

(v) Provide an exhaustive list of air pollutant emission sources, including any nearby emission sources which are likely to have impact on the project based on the analysis of the constructional and operational activities of the project in (i) above. Examples of constructional stage emission sources include stock piling, blasting, concrete batching and vehicular movements on unpaved haul roads on site,......etc. Examples of operational stage emission sources include industrial boiler plants and vehicular flow,......etc. Confirmation of the validity of the assumptions and the magnitude of the activities (e.g. volume of construction materials handled, traffic mix and volume on a road etc.) shall be obtained from the relevant government department/authorities and documented.

Constructional air quality impact

(vi) The Applicant shall follow the requirements of the Air Pollution Control (Construction Dust) Regulation in dust control to ensure construction dust impacts are controlled within the relevant standards as stipulated in section 1 of Annex 4 of the TM. An audit and monitoring program during constructional stage shall be initiated to verify the effectiveness of the control measures and to ensure that the construction dust levels be brought under control.

(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 (xi) to (xv) 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. The Applicant shall follow (xi) to (xv) below when carrying out the quantitative assessment.

(ix) For calculation of future road traffic air pollution impact, this shall be based on the highest emission strength from the road within the next 15 years upon commencement of operation of the proposed road. The Applicant shall demonstrate that the selected year of assessment represents the highest emission scenario given the combination of vehicular emission factors and traffic flow for the selected year.

(xi) The Applicant shall apply the general principles enunciated in the modelling guidelines (paragraph 3.3.1.3 above) while making allowance for the specific characteristic of each project. This specific methodology must be documented in such level of details (preferably with tables and diagrams) to allow the readers of the assessment report to grasp how the model is set up to simulate the situation at hand without referring to the model input files. Details of the calculation of the emission rates of air pollutants and a map showing all the road links for input to the modelling 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 Air Policy Group is advised.

(xii) The Applicant shall, based on the nature of the activities analysed in (v) above, identify the key/representative air pollutant parameters (types of pollutants and the averaging time concentration) to be evaluated and provide explanation for choosing these parameters for the assessment of the impact of the project.

(c) Proposals for Noise Mitigation Measures

After rounding of the predicted noise levels according to the U.K. Department of Transport's "Calculation of Road Traffic Noise" (1988), the Applicant shall propose direct technical remedies within the project limits in all situations where the predicted traffic noise level exceeds the criteria set in Table 1A of Annex 5 in the TM by 1 dB(A) or more. Specific reasons for not adopting certain direct technical remedies in the design to reduce the traffic noise to a level meeting the criteria in the TM or to maximize the protection for the NSRs as far as possible should be clearly quantified and laid down. The total number of dwellings, classrooms and other noise sensitive element that will be benefited by the provision of direct technical remedies should be provided.

The total number of dwellings, classrooms and other noise sensitive elements that will still be exposed to noise above the criteria with the implementation of all recommended direct technical remedies shall be quantified.

In case where a number of the NSRs cannot all be protected by the recommended direct technical remedies, the Applicant shall identify and estimate the total number of existing dwellings and other noise sensitive elements which may qualify for indirect technical remedies under the ExCo directive "Equitable Redress for Persons Exposed to Increased Noise Resulting from the Use of New Roads", the associated costs and any implications for such implementation. For the purpose of determining the eligibility of the affected premises for indirect technical remedies, reference shall be made to the set of following three criteria:

(1) the predicted overall noise level from the new road together with other traffic noise in the vicinity must be above a specified noise level (e.g. 70 dB(A) for domestic premises and 65 dB(A) for education institutions, all in L10(1 hr));

(2) the predicted overall noise level is at least 1.0 dB(A) more than the prevailing traffic noise level, i.e. the total traffic noise level existing before the works to construct the road were commenced; and

(3) the contribution to the increase in the predicted overall noise level from the new road must be at least 1.0 dB(A).

(vii) Assessment of Side Effects and Constraints

The Applicant shall identify, assess and propose means to minimize any side effects and to resolve any potential constraints arising from the inclusion of any recommended direct technical remedies.

(viii) Evaluation of Constraints on Planned Noise Sensitive Developments/Land Uses

For planned noise sensitive uses which will still be affected even with all practicable direct technical remedies in place, the Applicant shall propose, evaluate and confirm the practicality of additional measures within the planned noise sensitive uses and shall make recommendations on how these noise sensitive uses will be designed for the information of relevant parties.

The Applicant shall take into account the agreed environmental requirements/constraints identified by the study to assess the development potential of the concerned sites which shall be made known to the relevant parties.
