4                             Air Quality

4.1                       Introduction

4.1.1                  This section presents the assessment on potential air quality impacts arising from construction and operation of the Project.  The air quality impact assessment was conducted and presented according to the requirements of Annex 4 and Annex 12 of the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM) and the EIA Study Brief No. ESB-299/2017 issued in August 2017.

4.2                       Environmental Legislation, Standards and Guidelines

General

4.2.1                  The criteria for evaluating air quality impacts and the guidelines for air quality impact assessment are set out in Annex 4 and Annex 12 of the EIAO-TM.

Air Quality Objectives

4.2.2                  The Air Pollution Control Ordinance (APCO) (Cap. 311) and its subsidiary regulations provide the statutory framework for controlling the air pollutants from a variety of sources. The Hong Kong Air Quality Objectives (AQOs) stipulate the maximum acceptable concentration for a number of criteria air pollutants. The AQOs are presented in Table 4.1.

Notes:

(1)   All measurements of the concentration of gaseous air pollutants, i.e., sulphur dioxide, nitrogen dioxide, ozone and carbon monoxide, are to be adjusted to a reference temperature of 293Kelvin and a reference pressure of 101.325 kilopascal.

(2)   Respirable suspended particulates mean suspended particles in air with a nominal aerodynamic diameter of 10 μm or less.

(3)   Fine suspended particulates mean suspended particles in air with a nominal aerodynamic diameter of 2.5 μm or less.

Technical Memorandum on EIA Process

4.2.3               The EIAO-TM stipulates that the hourly Total Suspended Particulates (TSP) level at any air sensitive receivers should not exceed 500µg/m3 (measured at 25şC and one atmosphere) for construction dust impact assessment.

4.2.4               In accordance with the EIAO-TM, odour level at any air sensitive receiver should meet 5 odour units based on an averaging time of 5 seconds for odour impact assessment.

Air Pollution Control (Construction Dust) Regulation

4.2.5               Notifiable and regulatory works are under the control of the Air Pollution Control (Construction Dust) Regulation.  This Project is expected to involve both notifiable works and regulatory works.  The Contractors are required to inform EPD and adopt proper dust suppression measures to minimize dust emissions while carrying out construction works.

Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation

4.2.6                  Under the Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation, only approved or exempted non-road mobile machineries with a proper label are allowed to be used in the construction site.  The contractors are required to ensure the adopted non-road mobile machinery under the Project could meet the prescribed emission standards and requirement.

4.3                       Baseline Conditions

Existing Background Air Quality

4.3.1                  The nearby EPD Air Quality Monitoring Station (AQMS) are located at Tuen Mun and Yuen Long.  The recent 5 years (2015 – 2019) air quality monitoring data collected from the Tuen Mun and Yuen Long AQMS are summarized in Table 4.2.

Notes:

(1)     Concentrations which exceeded the AQOs are shown as bold and underlined.

(2)     With reference to the EPD’s “Guidelines on Choice of Models and Model Parameters”, the PATH-2016’s output of RSP concentrations are adjusted as below:

- 10th highest daily RSP concentration: add 26.5 µg/m3

- Annual RSP concentration: add 15.6 µg/m3

(3)     With reference to the EPD’s “Guidelines on the Estimation of FSP for Air Quality Assessment in Hong Kong”, the background FSP concentrations are estimated by the following equation by adopting the background RSP concentrations extracted from PATH-2016 model.

- Annual FSP concentration (µg/m3) = 0.71 x RSP

- Daily FSP concentration (µg/m3) = 0.75 x RSP

4.3.4                  According to Table 4.3, the future background air quality would be improved.  There would be no exceedance of AQOs for all air quality pollutants except ozone.

4.4                       Air Sensitive Receivers

4.4.1                  The assessment area for the air quality impact is defined by a distance of 500m from the boundary of the Project Site during construction phase and 500m from the boundary of the PDA and road junction improvement during operation phase. Figure 4.1a and Figure 4.1b illustrate the assessment area for construction phase and operation phase respectively.

4.4.2                  In accordance with Annex 12 of the EIAO-TM, any domestic premises, hotel, hostel, hospital, clinic, nursery, temporary housing accommodation, school, educational institution, office, factory, shop, shopping centre, place of public worship, library, court of law, sports stadium or performing arts centre are classified as air sensitive receivers (ASRs).

4.4.3                  Representative existing, planned and committed ASRs within the assessment area have been identified based on the topographic maps supplemented by site surveys, Outline Zoning Plans (OZPs), other published plans in the vicinity of the Project Site.   

4.4.4                  The locations of the representative ASRs for construction phase impact assessment and operation phase impact assessment are shown in Figure 4.2 to Figure 4.7 and Figure 4.8 to Figure 4.13, and are summarized in Table 4.4 and Table 4.5 respectively. Planned ASRs under this Project are not regarded as ASRs during construction phase impact assessment since construction is being carried out within the Project Site and hence, these ASRs do not exist yet.

4.5                       Identification of Pollution Sources

Construction Phase

4.5.1                  Construction works of the Project include site clearance, land decontamination, site formation, piling works, superstructure works, roadworks (i.e. realigned Hong Po Road and proposed Road L7), pipeworks, utility works and road improvement works. The location of the construction works, tentative work phasing arrangement and the tentative construction programme are provided by the Project Engineer and presented in Appendix 4.1.  For piling works, superstructure works and minor supporting works including pipeworks, utility works and road improvement works, their extent of excavation, unloading/loading of spoils, material handling, and site area exposed to wind erosion are very limited and constructed by sections. Thus, the associated dust impact is expected to be insignificant and in short duration.  Considering that the potential dust impacts from these construction works are localized and well-controlled by the implementation of dust suppression measures, these works will give rise to insignificant construction dust impacts and comply with the recommended limits outlined in Section 4.2 at the nearby ASRs. Hence, these minor works are not included in the quantitative construction dust impact assessment. 

4.5.2                  The major dusty construction works for the Project to be considered in the quantitative assessment include:

·            Site Clearance;

·            Land decontamination;

·            Site formation works and roadworks for SHR Site Extension – Residential Site, Proposed Sewerage Pumping Station, Realigned Hong Po Road, Proposed Road L7, San Hing Road Site (SHR Site) – Residential Site, Hong Po Road Site (HPR Site) and School Sites at SHR Site Extension and SHR Site.

4.5.3                  Heavy construction activities such as excavation, material handling and wind erosion of exposed site area would contribute to construction dust.  The major dusty construction works will be located within the PDA boundary as presented in Figure 4.2.  As discussed in Section 4.5.1, the ASRs within 500m of the PDA boundary are considered for the quantitative dust impact assessment. The construction period is conservatively assumed to be 7 days per week and 12 operation hours per day from 07:00 to 19:00.  Wind erosion is assumed for non-operation hours from 19:00 to 07:00 of the follow day.

4.5.4                  Construction vehicles, estimated to be about 30 round trips per hour, will generally make use of Hong Po Road to access the Project Site. Dust emissions from these vehicles will generally be limited within the worksites and have already been taken into account in the derivation for heavy construction activities. Watering facilities will be provided at all vehicular egress. All construction vehicles will be thoroughly washed and those loaded with dusty materials will be covered by clean impervious sheets prior to leaving the construction site. Hence, the dust nuisance from construction vehicles outside the construction site is unlikely to be significant.

4.5.5                  Concurrent projects located within the 500m assessment area for quantitative assessment during construction phase of the Project have been identified.  The major concurrent projects include Site 4A (South), Site 4A (East) and Site 5 of the Tuen Mun Area 54 Development (i.e. TM AREA 54) and Tuen Mun Area 29. According to the information provided by the Housing Department at the time of preparing this EIA report, the construction period for these sites are between Year 2021 and Year 2027 with site formation work completed by early 2025. Considering that the construction works of the Project will commence in Year 2025 and that the construction works in TM AREA 54 will mainly be superstructure works with no dusty construction activities, such as site formation work, take place by then, no cumulative construction dust emission from these work sites are anticipated. 

4.5.6                  Apart from the construction dust emissions, cumulative air quality impact at the representative ASRs would also be expected due to the background pollutant concentrations, vehicular emissions from existing open roads, portal emissions from the noise enclosure at Tsing Lun Road and industrial emissions from two identified chimneys within the assessment area.  These cumulative sources are shown in Figure 4.14 to Figure 4.15.

4.5.7                  In addition, an asphalt plant in Lam Tei Quarry is identified as a major source within 4km of the Project Site, and hence would be included as an emission source in the assessment. Location of the asphalt plant and its sources are shown in Figure 4.16.  

4.5.8                  Potential sources of air quality impacts would be dust emissions including total suspended particulates (TSP), respirable suspended particulates (RSP) and fine suspended particulates (FSP) generated during heavy construction activities. 

4.5.9                  Fuel combustion from the use of powered mechanical equipment (PME) during construction works would be a source of NO2, SO2 and CO.  Legal control is imposed on the types of fuel allowed for use and their sulphur contents in commercial and industrial processes under the Air Pollution Control (Fuel Restriction) Regulation, which was enacted in 1990. To improve air quality and protect public health, EPD has introduced the Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation, which came into operation in 2015 to regulate emissions from machines and non-road vehicles. The Development Bureau’s Technical Circular No.1/2015—Emissions Control of Non-road Mobile Machinery in Capital Works Contracts of Public Works also promulgates such requirements in new capital works contracts of public works. Since then, only approved or exempted non-road mobile machinery are allowed to be used in construction sites. In addition, the use of diesel or petrol powered generators will be avoided. Mains electricity or battery powered equipment will be adopted where practicable. The emissions from the equipment used are therefore considered insignificant.  Therefore, only TSP, RSP and FSP are considered in the construction dust impact assessment. 

Operation Phase

4.5.10              Potential air quality impacts during operation phase would be associated with the vehicular emissions from open sections of existing roads, proposed roads and proposed junction improvements within the assessment area.  Apart from the vehicle emissions, cumulative air quality impact at the representative ASRs would also be expected due to the background pollutant concentrations, portal emissions from the noise enclosure at Tsing Lun Road and industrial emissions from the identified chimneys within the assessment area. The locations of these emission sources are shown in Figure 4.17.

4.5.11              Emissions from the asphalt plant at Lam Tei Quarry as shown in Figure 4.16, would also be included as an emission source in the assessment since it is identified as a major source within 4km of the Project Site.

4.5.12              The Tuen Mun Area 54 Sewage Pumping Station (TM Area 54 SPS) has been identified as an existing odour source during site surveys.  The proposed San Hing Road Sewage Pumping Station (SHR SPS) will also be a potential odour emission source within the PDA. In addition, there are several existing refuse collection points (RCPs) within the assessment area. The location of these odour sources are shown in Figure 4.18.  Future RCPs within the proposed housing sites are also considered as potential odour sources within the PDA.  However, the location of these future RCPs are not available at this stage and subject to further study of housing layout by HKHA at a later stage.

Vehicular Emission from Open Road and Portal

4.5.13              Vehicular and portal emission comprises mainly NOx, RSP, FSP and emissions from the identified industrial sources comprise mainly NOx, RSP, FSP and SO2.  Therefore NO2, RSP, FSP and SO2 will be considered in the operation phase air quality impact assessment. 

4.5.14              CO is a typical air pollutant emitted from road transport.  However, the measured CO concentrations in Hong Kong were well below the AQO limit.  Due to the large margin to AQO, CO will not be considered as a pollutant of concern.  For Ozone (O3) which will not be generated by the above identified sources, NOx emissions from vehicles and chimneys have the potential to react with and remove O3 in the air, and regions with heavy traffic normally have lower ozone levels than areas with light traffic.  O3 is therefore not considered as a critical air pollutant.  Leaded petrol has been banned in Hong Kong since April 1999.  The measured concentrations of lead in Hong Kong were much lower than the AQO limit.  Therefore, lead is not considered as a critical air pollutant and will not be included in this assessment.

Industrial Emission

4.5.15              Based on desktop review and verification by site surveys, three premises with existing active chimneys were identified within the assessment area.  The locations of the identified chimneys are presented in Figure 4.17. 

4.5.16              One chimney (Chimney ID: S1) is used for day-to-day operation of a restaurant.  As reported by a staff at the restaurant, diesel fuel is used and the chimney operates from 10:00 to 14:00 and 16:00 to 21:00 daily.  However, no fuel consumption information could be provided.  Given that no other fuel usage information is available, EPD’s Installation Regulation (IR) records have been checked and confirmed that there are no records for the concerned restaurant.  As such, the fuel usage threshold (25L/hr) stipulated in CAP 311A Air Pollution Control (Furnaces, Ovens and Chimneys) (Installation and Alteration) Regulations will be applied. 

4.5.17              As for the other chimney (Chimney ID: S2), it is connected to the stove of a roasted pig processing factory.  Operation details such as fuel consumption, type of fuel, and operation hours has been obtained from the operator.

4.5.18              Apart from the above identified chimneys, there are 16 potential emission points (Chimney ID: S3 – S18) located in the Castle Peak Hospital.  Relevant operation details such as fuel consumption, type of fuel, and operation hours have been obtained from the Management Unit of the Castle Peak Hospital.

4.5.19              In addition to the above identified chimneys within the assessment area, there are 14 emission sources (Chimney ID: AEP1 – AEP3, AEP7 – AEP17) located in the asphalt plant at Lam Tei Quarry, which was identified as a major pollutant source within 4km of the Project Site. Relevant emission details have been obtained from its specified process license.

Odour Emission

4.5.20              The proposed SHR SPS will be located at about 86m and 62m away from the existing ASRs (R27) and planned ASRs (P30) respectively.  Potential odour emission from wet well, inlet chamber and screen chamber are the possible odourous sources of the proposed SHR SPS.  These sources would be housed inside reinforced concrete structure and the foul air would be ventilated to a deodouriser for treatment before discharge to the environment.  Activated carbon type deodouriser with odour removal efficiency of 95% and above is commonly used in DSD’s pumping stations (e.g. 95% at Queen’s Hill SPS[1], 99.5% at Jordan Valley Box Culvert SPS[2] and Lin Cheung Road Temporary SPS[3]) and thus is considered technical feasible.  In order to better protect both existing, committed and planned ASRs located in the vicinity of the proposed SHR SPS, a dedouriser with 99.5% odour removal efficiency will be adopted to avoid the potential odour emission to the maximum practicable extent.  The ventilation system would also maintain a negative pressure within the facilities.  In addition, the deodouriser exhaust outlet of the proposed SHR SPS would be located away from the nearby ASRs as far as practicable.

4.5.21              Screening wastes will be stored in covered containers, packed and handled carefully inside the screen houses; and remained in the covered containers before disposal at landfill site to avoid off-site odour nuisance along the disposal route.  Therefore, adverse on-site or off-site odour impacts due to the removal/handling of the screening wastes is not anticipated.

4.5.22              Future RCPs within the PDA to serve the proposed Development.  Proper ventilation and deodourising and exhaust system will be provided to minimize the potential odour nuisance on the nearby ASRs.  Good housekeeping will also be adopted to enhance the hygiene of the RCPs by frequent washing, proper covering of refuse bins, closing of roller shutters and proper maintenance of the ventilation, deodourising and exhaust system.  As such, the potential adverse odour impact on the nearby ASRs is not anticipated.

4.5.23              Under this Project, replacement of existing 4 nos. of sewage pumps with larger pumping capacity has been proposed at TM Area 54 SPS. The existing pump capacity of 0.59m3/s will be increased to 0.82m3/s. The odour emission strength assessed under the approved EIA Report of the TM Area 54 SPS and Environmental Permit FEP-01/381/2009 is based on a pumping capacity of 1.03 m3/s. Hence, the increase of pumping capacity to 0.82m3/s proposed under this Project would not increase the odour emission strength assessed in the approved EIA report. The odour assessment findings in the approved EIA Report is therefore considered valid and applicable. Based on the contour plots in the approved EIA Report, the area subjected to adverse odour impacts is localized within the vicinity of the SPS. The permit holder/operator of the TM Area 54 SPS (i.e. Drainage Services Department) is required to comply with the requirements as stipulated in the Environmental Permit FEP-01/381/2009 to control potential environmental impacts. With the implementation of the mitigation measures, no adverse odour impact during operation of the sewage pumps is expected. Adverse odour impact at the Project Site due to TM Area 54 SPS is thus not anticipated.

4.5.24              For the several RCPs identified, it was observed during site surveys that the scale of operation of these RCPs are typical to other RCPs in rural area and waste are stored in enclosed bins with daily collection. No notable odour smell was detected near the RCPs. Adverse odour impact from these RCPs is not anticipated.

4.5.25              With the installation of deodourising units with 99.5% odour removal efficiency and the aforementioned design measures at the proposed SHR SPS and the future RCPs, it is anticipated that there would be no adverse odour impact from the proposed SHR SPS and future RCPs at the nearby ASRs. Besides, considering that adverse odour impact from TM AREA 54 SPS and the existing nearby RCPs are not anticipated, quantitative cumulative odour impact assessment is considered not necessary.

4.6                       Construction Phase Impact Assessment

Assessment Methodology

General

4.6.1                  In line with EPD’s “Guidelines on Assessing the ‘TOTAL’ Air Quality Impacts”, all three tiers of emissions that will contribute to the total air quality impacts on ASRs within the assessment area have been identified, including:

(1)   Primary Contributions: Project Induced

(2)   Secondary Contributions: Pollutant-emitting activities in the immediate neighborhood

(3)   Background Contributions: Pollution not accounted for by (1) and (2)

4.6.2                  Primary and secondary contributions are near-field source impacts due to sources within the assessment area such as construction dust, vehicular emission from existing road network and proposed roads (with proposed junction improvements in place) as well as industrial emissions from identified chimneys. Background contributions are far-field source impacts outside the assessment area and are predicted using the PATH model. The cumulative construction air quality impact assessment is a combination of all three tiers of contributions and thus has taken into account the near-field and far-field sources.

4.6.3                  Meteorological data in Grids (19,43), (19,44), (19,45), (20,43), (20,44), (20,45), (21,43), (21,44) and (21,45) in the PATH-2016 system are considered relevant as they entirely cover the assessment area as shown in Figure 4.1.

Construction Dust Associated with the Project

4.6.4                  Potential construction dust impacts would mainly be related to the heavy construction activities such as excavation, material handling and wind erosion of exposed site area.  The 1-hr average TSP concentration, 24-hr average and annual average RSP and FSP concentration have been evaluated to assess the short and long-term dust impact from the Project on the ASRs, respectively.

4.6.5                  The emission factors for TSP, RSP and FSP have been determined from the emission factors of TSP together with the RSP and FSP proportions with reference to the Compilation of Air Pollutant Emission Factors, USEPA AP-42, 5th Edition, January 1995.  The key assumptions for the calculation of TSP, RSP and FSP emission factors are summarised in Table 4.6 below. 

4.6.6                  In order to control dust emission from the Project, regular watering under a good site practice will be adopted.  In accordance with the “Control of Open Fugitive Dust Sources” (USEPA AP-42) as given in Appendix 4.2, watering once per hour on exposed worksites and haul road is proposed to achieve dust removal efficiency of 91.7%.  These dust suppression efficiencies are derived based on the average haul road traffic of 40 vehicles per hour, average evaporation etc.  Any potential dust impact and watering mitigation would be subject to the actual site conditions.  For example, for a construction activity that produces inherently wet conditions or in cases under rainy weather, the above water application intensity may not be unreservedly applied.  While the above watering frequencies are to be followed, the extent of watering may vary depending on actual site conditions. Appendix 4.2 presents the calculation of dust emission factors and location of dust source.

Notes:

 [1] Percentages of RSP and FSP are referenced from Section 13.2.4.3 of the AP-42.

4.6.7                  Dust emission from construction vehicle movement will generally be limited within the confined worksites and the emission factor given in AP-42 S.13.2.3.3 has taken this factor into account. Watering facilities will be provided at every designated vehicular exit point.  Since all vehicles will be washed at exit points and vehicle loaded with the dusty materials will be covered entirely by clean impervious sheeting before leaving the construction site, dust nuisance from construction vehicle movement outside the worksites is unlikely to be significant.

4.6.8                  The heavy construction activities will be divided into eight phases according to the detailed construction programme. Particularly, Phase 3 and Phase 5 have been further divided into Phase 3a and Phase 3b as well as Phase 5a and Phase 5b. Only either Phase 3a or Phase 3b will occur at any one time and the same applies to Phase 5a and Phase 5b. Since the construction workfronts are expected to be moving around and affecting different ASRs at different times, the construction dust impact of all construction phases have been assessed.  The construction phasing is summarized in Table 4.7. The locations of workfronts in each construction phase are presented in Appendix 4.1.

Dust Dispersion Modelling Approach

4.6.9                  In line with EPD’s “Guidelines on Choice of Models and Model Parameters, near-field dispersions from point, area and volume sources were simulated by AERMOD – a model which has been developed based on steady-state Gaussian dispersion.  Assessment heights of the representative ASRs as listed in Table 4.4 have been adopted for the assessment. The model has adopted the following input data/parameters/options in the simulation:

·            “Urban” dispersion option used due to a number of residential buildings in vicinity;

·            Dry deposition option selected for the construction dust emissions (TSP and RSP);

·            Gradual Plume Rise and Stack-tip Downwash;

·            Buoyancy-induced Dispersion; and

4.6.10              The determination of surface characteristics parameter adopted in AERMOD is presented in Appendix 4.3.

4.6.11              For the construction dust emissions, dry deposition was applied in the AERMOD model for TSP and RSP.  The density of dust was assumed to be 2.5g/cm3.  Heavy construction activities and wind erosion as described in Table 4.6 have been assessed.  Particle Size distribution presented in Table 4.8 was adopted for TSP and RSP in the assessment.

Notes:

 [1] Reference from Table of Aerodynamic Particle Size Multiplier (k) for Equation 1, Section 13.2.4-4 of the AP-42.

4.6.12              Construction dust sources and wind erosion have been modelled as area sources.  Construction periods have been assumed to be 7 days per week and 12 operation hours per day from 07:00 to 19:00.  Wind erosion has been assumed for non-operation hours from 19:00 to 07:00 of the next day. 

Dust Emissions Associated with the Operation of Concurrent Sources

4.6.13              Approach for prediction of particulate emissions from open roads and portal is the same as operation phase assessment as described in Section 4.7, in which the dispersion model CALINE4 was used to assess the vehicular emission impact and AERMOD was used to assess the portal emission impact.   Particulate emissions from open road and portal was determined using the latest EMFAC-HK model (version 4.2). The eight construction phases have been allocated into two construction periods. Construction Period 1 covers Phases 1-7 with no Project roads commenced operation. Construction Period 2 covers Phase 8 with all Project roads (i.e. Realigned Hong Po Road, proposed Road L7) commenced operation. The earliest year within each construction period was conservatively adopted as the modelling year while the latest year within each construction period was conservatively adopted as the traffic data year.

4.6.14              The EMFAC modelling years and years of traffic data adopted for the respective construction phases are summarized in Table 4.9 below.

4.6.15              The traffic forecast of Year 2029 and Year 2030, which have been endorsed by the Transport Department, are presented in Appendix 4.4 while emission factors and derivation of emission rates are presented in Appendix 4.5.  Derivation of portal emissions is given in Appendix 4.6. The emission inventories of hourly RSP and FSP emission rates for each portal and road link are given in Appendix 4.7 and Appendix 4.8 respectively. The traffic forecast has already taken into account the traffic generated by all concurrent projects.

4.6.16              For industrial emissions from the two premises within the assessment area and the asphalt plant at Lam Tei Quarry, the prediction approach is the same as the operation air quality assessment as described in Section 4.7, in which the dispersion model, AERMOD, was used to assess the industrial emission impact.

Background Pollutant Contribution

4.6.17              The Pollutants in the Atmosphere and their Transport over Hong Kong model (PATH-2016) released by EPD was used to estimate the background air quality.  As construction works will commence in Year 2025, PATH-2016 data for Year 2020 of the concerned grids have been adopted as the background concentration.

4.6.18              With reference to the EPD’s “Guidelines on Choice of Models and Model Parameters”, the PATH-2016’s output of RSP concentrations have been adjusted as follows:

·         10th highest daily RSP concentration: add 26.5 µg/m3

·         Annual RSP concentration: add 15.6 µg/m3

4.6.19              The TSP and FSP concentrations are not available from PATH model, the background hourly TSP concentrations have been assumed to be same as RSP as the best estimation while the background FSP concentrations have been determined based on the conservative corrections shown in Table 4.10 below, which is recommended in EPD’s “Guidelines on the Estimation of FSP for Air Quality Assessment in Hong Kong”.

Table 4.10 - Conversion factors for RSP/FSP

Annual (µg/m3)

Daily (µg/m3)

FSP = 0.71 x RSP

FSP = 0.75 x RSP

4.6.20              The predicted overall cumulative impact levels at the representative ASRs will share the same time domain as the meteorological data and background levels, and hence will all be synchronised.

Assessment Results

4.6.21              The predicted maximum 1-hour TSP concentrations, 10th highest 24-hour and annual RSP/FSP concentrations are presented in Table 4.11 and detailed in Appendix 4.9.  With the implementation of hourly watering, there would be no exceedances of TSP, RSP and FSP criteria under all construction phases.  The results suggest that there would not be a single worst affected phase for all ASRs.  As the construction workfronts will move around throughout the construction period, individual ASRs will be affected by different construction phase(s) when the associated workfronts are located closest to the ASRs.

4.6.22              For majority of representative ASRs, the worst impact due to Project works generally occur at 1.5mAG, which are closest to the at-grade construction sites. ASRs at higher levels are generally less affected by construction dust since particulates would likely settle before reaching the ASRs.  

4.6.23              A 50x50m grid is used to generate pollution contours. Contours of 1-hour TSP concentrations, 10th highest 24-hour and annual RSP/FSP concentrations at the worst affected level (i.e. 1.5mAG) for each construction phase are illustrated in Figure 4.19 to Figure 4.68. Contour plots indicate that there are no exceedances at all sensitive uses. Although the exceedance zone of 24-hour and annual RSP during Phase 3a to Phase 6 of Construction Period encroaches into the edge of TM AREA 54 Site 1 & 1A, there is no air sensitive use within the exceedance zone.

Incremental Air Quality Impact

4.6.24              The breakdown of various source contributions for the predicted maximum 1-hour TSP concentrations, 10th highest 24-hour and annual RSP/FSP concentrations throughout the construction period are presented in Table 4.12 to Table 4.14 below.

4.6.26              The major contributor to the cumulative 1-hour TSP construction dust impact is the background contribution for most ASRs, except for several ASRs in vicinity of the site formation works. Even said that, although the Project contributions are greater than background contributions, the cumulative TSP impact is well below the relevant criteria of 500 µg/m3. For 10th highest 24-hour and annual RSP/FSP concentrations, background contributions from far-field sources are the major contributors to the cumulative RSP/FSP impact. Particularly, the small FSP contributions at all ASRs indicate that construction works is not a major source of FSP.

Mitigation Measures

4.6.27              Exceedance of TSP, RSP and FSP criteria is not expected provided that hourly watering on exposed worksites and haul road is implemented.  In addition, the Contractor is also obliged to follow the procedures and requirements given in the Air Pollution Control (Construction Dust) Regulation.  It stipulates the construction dust control requirements for both Notifiable (e.g. site formation) and Regulatory (e.g. road opening) Works to be carried out by the Contractor.  The following dust suppression measures should be incorporated by the Contractor to control dust nuisance through the construction phase:

·            Any excavated or stockpile of dusty material should be covered entirely by impervious sheeting or sprayed with water to maintain the entire surface wet and then removed or backfilled or reinstated where practicable within 24 hours of the excavation or unloading;

·            Any dusty materials remaining after a stockpile is removed should be wetted with water and cleared from the surface of roads;

·            A stockpile of dusty material should not be extended beyond the pedestrian barriers, fencing or traffic cones;

·            The load of dusty materials on a vehicle leaving a construction site should be covered entirely by impervious sheeting to ensure that the dusty materials do not leak from the vehicle;

·            Where practicable, vehicle washing facilities with high pressure water jet should be provided at every discernible or designated vehicle exit point. The area where vehicle washing takes place and the road section between the washing facilities and the exit point should be paved with concrete, bituminous materials or hardcores;

·            When there are open excavation and reinstatement works, hoarding of not less than 2.4m high should be provided as far as practicable along the site boundary with provision for public crossing. Good site practice shall also be adopted by the Contractor to ensure the conditions of the hoardings are properly maintained throughout the construction period;

·            The portion of any road leading only to construction site that is within 30m of a vehicle entrance or exit should be kept clear of dusty materials;

·            Surfaces where any pneumatic or power-driven drilling, cutting, polishing or other mechanical breaking operation takes place should be sprayed with water or a dust suppression chemical continuously;

·            Any area that involves demolition activities should be sprayed with water or a dust suppression chemical immediately prior to, during and immediately after the activities so as to maintain the entire surface wet;

·            Where a scaffolding is erected around the perimeter of a building under construction, effective dust screens, sheeting or netting should be provided to enclose the scaffolding from the ground floor level of the building, or a canopy should be provided from the first floor level up to the highest level of the scaffolding;

·            Any skip hoist for material transport should be totally enclosed by impervious sheeting;

·            Every stock of more than 20 bags of cement or dry pulverised fuel ash (PFA) should be covered entirely by impervious sheeting or placed in an area sheltered on the top and the 3 sides;

·            Cement or dry PFA delivered in bulk should be stored in a closed silo fitted with an audible high-level alarm which is interlocked with the material filling line and no overfilling is allowed;

·            Site layout should be planned such that machinery and dusty activities (e.g. haul roads, stockpiling areas) are located away from ASRs as far as possible;

·            Construction machinery should be maintained regularly so as to ensure no deterioration on the emission performance;

·            Solid screens or barriers should be erected around dusty activities;

·            The use of diesel or petrol powered generators should be avoided and mains electricity or battery powered equipment should be adopted where practicable;

·            Loading, unloading, transfer, handling or storage of bulk cement or dry PFA should be carried out in a totally enclosed system or facility, and any vent or exhaust should be fitted with an effective fabric filter or equivalent air pollution control system; and

·            Exposed earth should be properly treated by compaction, turfing, hydroseeding, vegetation planting or sealing with latex, vinyl, bitumen, shortcrete or other suitable surface stabiliser within six months after the last construction activity on the construction site or part of the construction site where the exposed earth lies.

Residual Impact

4.6.28              With the implementation of hourly watering on exposed worksites and haul road and dust control measures as stipulated in the Air Pollution Control (Construction Dust) Regulation, the predicted 1-hour TSP, 24-hour and annual RSP/FSP concentrations at all ASRs in the vicinity of the construction sites would comply with the respective criteria.  Hence, no residual air quality impact during construction phase is anticipated.

4.7                       Operation Phase Impact Assessment

Assessment Methodology

General

4.7.1                  In line with EPD’s “Guidelines on Assessing the ‘TOTAL’ Air Quality Impacts”, all three tiers of emissions that will contribute to the total air quality impacts on ASRs within the assessment area have been identified, including:

(1)   Primary Contributions: Project Induced

(2)   Secondary Contributions: Pollutant-emitting activities in the immediate neighborhood

(3)   Background Contributions: Pollution not accounted for by (1) and (2)

4.7.2                  Primary and secondary contributions are near-field source impacts due to sources within the assessment area such as vehicular emission from existing road network and proposed roads (with proposed junction improvements in place) as well as industrial emissions from identified chimneys. Background contributions are far-field source impacts outside the assessment area and are predicted using the PATH model. The cumulative operation air quality impact assessment is a combination of all three tiers of contributions and thus has taken into account the near-field and far-field sources.

4.7.3                  Meteorological data and background contributions in Grids (19,42), (19,43), (19,44), (19,45), (20,42), (20,43), (20,44), (20,45), (21,43), (21,44) and (21,45) in the PATH-2016 system are considered relevant as they entirely cover the assessment area as shown in Figure 4.2.

EMFAC-HK v4.2

4.7.4                  Vehicular tailpipe emissions from open roads were calculated based on the EMFAC-HK v4.2 model available at the time of preparing this report.  The input parameters made are summarized as follows:

·            Geographical Area: “Hong Kong” was selected as the Geographical Area

·            Season or Month: As per EPD’s Guideline, “Annual” was selected in this study to evaluate the highest vehicle emission within the Model Year

·            Modelling Mode: The EMFAC mode was used to generate emission factors in grams of pollutant emitted per vehicle activity for NOx, NO2, RSP and FSP. The NO2 generated was then subtracted from NOx to generate the emission factors for NO.

·            Exhaust/Evaporation Technology Fractions: Vehicle classes were grouped with different exhaust/ evaporation technology group indexes and technology fractions. Each technology group represents a distinct emission control technology.  Default exhaust/ evaporation technology fractions has been adopted in this assessment.

·            Population and Accrual Rate: Default vehicle populations forecast and accrual rate in EMFAC-HK has been adopted where applicable.

·            Vehicle Kilometre Travelled (VKT): VKT is a product of the number of vehicles and the road length travelled in the assessment area. The peak flows and the diurnal variations were predicted by the Project Traffic Consultant for each assessment year for the 16 vehicle classes defined in EPD’s “Guideline on Modelling Vehicle Emissions” for road carriageways within the 500m assessment area.

·            Trips: Default trips and VKT for HK total have been adopted.  Detailed impact rates were generated with respect to each combination of temperature, relative humidity and speed for running exhaust emission, and combination of temperature and duration for cold start emission, if applicable.

·            Temperature and Relative Humidity: These refer to the simulated year-round temperature and relative humidity available from the relevant PATH-2016 Grids that coincide with the assessment area as discussed in Section 4.4.  Since the range of temperature and relative humidity may vary across Grids, the overall maximum and minimum among all the Grids have been adopted uniformly across all the Grids.  For input configuration, the temperature was set to range from the lower to upper bound of the mean temperature of each hour in step of 5°C, and similarly for relative humidity in step of 10%.

Determination of Assessment Year and Derivation of Vehicular Emission Rates

4.7.5                  According to Appendix B, Clause 5 (iv) of the EIA Study Brief for the Project, the air pollution impacts of future road traffic shall be calculated based on the highest emission strength from the road vehicles in the assessment area within the next 15 years after the first population intake year of the Project or within the next 5 years after the full population intake year of the Project, whichever is later.  The selected assessment year shall represent the highest emission scenario given the combination of vehicular emission factors and traffic flow for the selected year.

4.7.6                  Based on the tentative implementation programme, population intake for the SHR Site, SHR Site Extension, and HPR Site will be in Years 2031, 2030, and 2033 respectively.  In order to determine the highest emission scenario and the worst assessment year, EMFAC-HK model runs have been carried out with emission factors and the projected traffic forecast for Year 2030 (first population intake i.e. commissioning), Year 2031 (second population intake), Year 2033 (full population intake), Year 2039 (interim year), and Year 2045 (15 years after commissioning).  In addition, as the realigned Hong Po Road and the proposed Proposed Road L7 will both be commissioned in Year 2029, the scenario for Year 2029, which has adopted Year 2029 vehicular emission factors together with the projected traffic data in Year 2029 has also been assessed.

4.7.7                  The traffic forecast data of the above selected modelling years were provided by the Project Traffic Engineer, which have been endorsed by the Transport Department, and is presented in Appendix 4.10. The traffic forecast has already taken into account the traffic generated by all concurrent projects.

4.7.8                  Emission factors generated from EMFAC-HK model v4.2 (NOx, NO2, RSP, FSP) were used to calculate the emission rate for each road link at different times. The initial NO2 have also been subtracted from the total NOx to obtain the residual NO tailpipe running and starting emission rates.

4.7.9                  For running emissions, where applicable, the maximum running exhaust emission rates arising from all combinations of temperature and relative humidity with respect to each combination of speed and vehicle class have been adopted.  For each road link, the hourly running exhaust emission rate (NO2, NO, RSP, FSP) for each vehicle class was determined by the running exhaust emission rate for the average road speed of the concerned road link. The hourly composite running exhaust emission rate (NO2, NO, RSP, FSP) was determined by:

4.7.10              Starting emissions are applicable to roads identified with cold start. Maximum starting emissions (g/trip) of different durations (from 5-720min) have been adopted.

4.7.11              Emission factors and derivation of emission rates of the above selected modelling years are presented in Appendix 4.11.

4.7.12              The calculated total vehicular emissions of NO2, NO, RSP and FSP from the roads in the assessment area of the above selected modelling years have been compared and summarized in Table 4.15 below.

4.7.13              The highest vehicle emission year was found to be Year 2029, which is the combination of Year 2029 vehicular emission factors together with the projected traffic data in Year 2029, and hence has been selected as the assessment year for the operation phase air quality impact assessment to represent the worst case scenario.

4.7.14              In addition, in view that full population intake has not yet taken place in Year 2029, Year 2033 will be taken as an additional assessment year to represent the worst case scenario with full population intake, where all site access roads would also be commissioned.

Vehicular Emissions Dispersion Modeling Approach

4.7.15              In line with EPD’s “Guidelines on Choice of Models and Model Parameters, vehicular emission impacts arising from open roads has been modelled by CALINE4 – a model that was developed by USEPA based on a steady-state Gaussian dispersion.

4.7.16              In this assessment, the CALINE4 model has adopted the following input data/parameters for ASRs in the same grid in the PATH-2016 system in the dispersion simulation:

·            Wind direction and speed from meteorological data from PATH-2016

·            Hourly mixing heights interpolated by PCRAMMET but capped between the minimum and maximum value measured at King’s Park AWS (2010), i.e. 121m and 1667m;

·            Hourly Pasquill stability classes generated by PCRMMET;

·            Horizontal wind direction fluctuations at 22.5°, 22.5°, 17.5°, 12.5°, 7.5°, 3.8° selected based on PCRAMMET generated stability classes matching A, B, C, D, E, F respectively and with correction for the average surface roughness;

·            A surface roughness factor of 100cm for all Grids since low-rise buildings are mostly identified within the assessment area; and

·            Settling velocity and deposition of default value of 0.0cm/s for all Grids

4.7.17              Existing and committed vertical and cantilever noise barriers, semi-enclosures and full enclosures as well as proposed as noise mitigation measures under this study along roads within the assessment area have also been considered in the assessment. Location of these noise mitigation measures are shown in Figure 4.69 to Figure 4.72.  For noise barriers and semi-enclosure along roads, the line source has been modelled at the top of the barrier or semi-enclosure and the mixing width was limited to the actual uncovered road width.  For cantilever noise barriers and semi-enclosure, it has been assumed that dispersion of traffic pollutants is in effect similar to physically shifting the road section towards the tip of the cantilever barrier or the opening side of the semi-enclosure.  Therefore, the alignment of the road section has been shifted by a distance equal to the covered extent in the CALINE4 model.

4.7.18              The location of noise mitigation measures proposed for this Project have been reviewed and revised throughout the course of the EIA Study.  The noise mitigation measures adopted in the CALINE4 model run is slightly different from the finalised package of noise mitigation measures.  The difference in noise mitigation measures between the set adopted in the CALINE4 model and the finalised package is shown in Appendix 4.22.  For ASRs in the immediate vicinity of these noise mitigation measures, a sensitivity test has been conducted to test the potential change of impact due to the minor change of these noise mitigation measures.  The change of impact before and after the minor change of noise mitigation measures is applied to the modelled results for corresponding ASRs of the assessed scenarios to represent the potential air quality impact from the Project. Details of the sensitivity test are presented in Appendix 4.22. Since the sensitivity test results indicated that the change of impact due to the minor change of mitigation measures at nearby ASRs are minor, the change of impact for ASRs further away from these noise mitigation measures is expected to be insignificant.  Hence, the modelled results based on the original CALINE4 model would still be representative to evaluate the potential air quality impact from the Project and the results are presented in the following sections.

4.7.19              Owing to the inherent limitation in the CALINE4 model, differences in the road elevations have to be restricted to the range of ±10m by default.  In setting up the model, elevations of the majority of roads have been defined as 0mAG instead of using the actual topographical level in mPD to circumvent the model limit. However, for elevated roads categorized as “Bridge” in the model, the height has been taken as the difference between its actual topographical level and the topographical level at the beginning of the elevation.

4.7.20              An emission inventory of the vehicular emission line sources is presented in Appendix 4.12.

Derivation of Portal and Industrial Emission Rates

4.7.21              Portal emission rates were calculated in a similar way as vehicular emission rate.  Air pollutants were assumed to be ejected as an air jet and emissions were modelled at the portals.  The approach adopted in the 2011 TM Area 54 ERR[4] has been used.  Since the noise enclosure is less than 30m long and no partition is designed at the central divider, the hourly portal emissions (NOx, RSP and FSP) have been assumed to be evenly distributed inside the enclosure following the same approach adopted in the 2011 TM Area 54 ERR. Portal emissions were modelled with reference to the “Permanent International Association of Road Congress Report (PIARC 1991)”. Under normal circumstances, air pollutants are assumed to be ejected from the full enclosure as an air jet and the total length of the air jet is about 100m, with two thirds of the emissions assumed to disperse in the first 50m of the air jet and another third of the emissions assumed to disperse within the second 50m in each direction of the full enclosure. However, since the concerned full enclosure is only 30m long, the total length of the air jet has therefore been assumed to be 30m. In each direction of the full enclosure, two thirds of the emissions have been assumed to disperse in the first 15m of the air jet and another third of the emissions have been assumed to disperse within the second 30m. The portal emissions were modelled as a total of four volume sources in each direction of the full enclosure using AERMOD.  With reference to Table 3.2 of the AERMOD User’s Guide[5], the initial lateral dimension (σy) of each volume source has been calculated by dividing the width of half of the enclosure (i.e. 8.035m) by 2.15, while the initial vertical dimension (σz) has been calculated by dividing the height of the enclosure (i.e. 5.7m) by 2.15.

4.7.22              The derivation of portal emissions and summary of portal emission inventory are given in Appendix 4.13 and Appendix 4.14 respectively.

4.7.23              Emission rates of identified chimneys have been derived based on emission factor from authoritative sources including local EPD studies, local regulations and the Compilation of Air Pollutant Emission Factors, USEPA AP-42, 5th Edition or obtained from relevant specified process license.

4.7.24              The derivation of industrial emissions and summary of industrial emission inventory are given in Appendix 4.15 and Appendix 4.16 respectively.

Portal and Industrial Emissions Dispersion Modelling Approach

4.7.25              In line with EPD’s “Guidelines on Choice of Models and Model Parameters”, near-field dispersions from point, area and volume sources have been simulated by AERMOD – a model which has been developed based on steady-state Gaussian dispersion.  Assessment heights of the representative ASRs as listed in Table 4.5 have been adopted for the assessment.  The model has adopted the following input data/parameters/options in the simulation:

·            “Urban” dispersion option used due to a number of residential buildings in vicinity;

·            Gradual Plume Rise and Stack-tip Downwash;

·            Buoyancy-induced Dispersion; and

·            Flat terrain adopted.

4.7.26              The determination of surface characteristics parameter adopted in AERMOD is presented in Appendix 4.3.

Vehicular Emission from Proposed Public Transport Interchanges (PTIs) and Car Parks

4.7.27              Covered PTIs for both bus and taxi/public light bus are proposed at SHR Site and HPR Site. According to the operation procedures specified in EPD’s Practice Note, Control of Air Pollution in Semi-Confined Public Transport Interchanges (ProPECC PN 1/98), the operator of PTI shall instruct all drivers using the PTI to switch off the vehicle engines while waiting to minimize idling emissions. Hence, idling activities within PTI should be very small under normal circumstances. Adequate ventilation systems will be provided to avoid accumulation of emissions within the PTI and designed in accordance with the ProPECC PN 1/98. The exhaust air outlets should be located away from nearby air sensitive uses to avoid causing air pollutant nuisance. If necessary, control equipment such as filters or scrubbing units should be used to minimize the impact induced on surroundings. Ventilation systems should also be maintained at regular intervals to ensure proper operation. The above measures will also be adopted at all car parks within the housing sites. With implementation of these measures, adverse air quality impact due to the proposed PTIs and car parks within the housing sites are not anticipated.

Background Pollutant Contribution

4.7.28              The Pollutants in the Atmosphere and their Transport over Hong Kong model (PATH-2016) released by EPD was used to estimate the background air quality. Since Year 2029 has been selected as the assessment year, PATH-2016 for Year 2020 of the mentioned grids have been adopted as the background concentration. The PATH-2016’s output RSP concentrations have been adjusted and background FSP concentrations have been estimated similarly to dust dispersion modelling in Section 4.6.8 – 4.6.9. It should be noted that the 2020 PATH model run has included the emissions from all the major emission sources in Hong Kong, Pearl River Delta Region, Guangdong Province, as well as the majority parts of China and Southeast Asia. The details of the emission sources adopted in the PATH model can be found at item (vi) and (viii) in EPD’s webpage[6].

4.7.29              For NO2, the vehicular emissions in the road network within the 500m study area have been removed from the relevant grids to avoid overestimation. The PATH model has been re-run and the hourly concentrations of all pollutants predicted by this updated PATH-2016 model have been adopted in the prediction of cumulative operation air quality impact.

Post-processing of Dispersion Modelling Results

4.7.30              Pollutant dispersion from vehicular emissions have been simulated using the CALINE4 model while portal and industrial emissions have been simulated using AERMOD model.  Dispersion results have been combined and post-processed for the different averaging periods required for comparison with the relevant AQOs.

4.7.31              For NOx in particularly, an algorithm has been built-in to convert a portion of NOx predicted at ASRs into NO2 using the Ozone Limiting Method (OLM) when they mix with the ambient O3.  The OLM assumes a conversion process that is stoichiometrically limited by the ambient O3 levels, and hence the latter can be used to predict the maximum convertible NO2 from NOx for superimposing onto the initial “out-of-tailpipe / in-stack” NO2 levels as the base level.

4.7.32              For NO2 from vehicular and portal emissions, the individual initial tailpipe NO2/NOx ratios of each EMFAC-HK vehicle type have been adopted to calculate the initial NO2 and residual NO tailpipe running and starting emission rates prior to conducting the dispersion modelling.  The total NO2 levels at receivers have been calculated as:

4.7.33              For NO2 from industrial emissions, with reference to industrial coal in Table 4.5 of the Heathrow Airport EIA Report, initial ratio of NO2/NOx = 10% is adopted.  The total NO2 levels at receiver have been calculated as:

4.7.34              For SO2 from industrial emissions, to enable SO2 levels to be compared with the 10-minute average criterion, the predicted hourly averages have been converted by multiplying factors suggested by Duffee[7] et. Al. (1991) in the post-processing of the summated total hourly SO2 levels as follows:

·           Conversion factor of 2.45, 2.45, 1.82, 1.43, 1.35, 1.35 to be applied based on the PCRAMMET generated stability classes matching any of the A, B, C, D, E, F respectively

Assessment Results

4.7.35              The predicted maximum 1-hour and annual NO2 concentrations, 10th highest 24-hour and annual RSP/FSP concentrations, 4th highest 10-min and 4th highest 24-hour SO2 concentrations in Year 2029 are presented in Table 4.16 and detailed in Appendix 4.17.  Although population intake for planned ASRs will not take place until Year 2030, Year 2031 and Year 2033, the planned ASRs have still been included in this assessment for Year 2029 to represent a worst case scenario.

Note:

[1] Impact at worst affected height is presented for each ASR.

[2] SO2 impact has been predicted for planned ASRs only but not existing ASRs since there is no SO2 impact induced by the Project.

[3] Worst affected height is at 1.5mAG for all ASRs.

[4] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R09 and R65 as well as 15mAG for R59.

[5] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R62-R65.

[6] Worst affected height is at 30mAG for all ASRs except at 30mAG for P33.

 

 

4.7.36              The results presented in Table 4.16 and Appendix 4.17 reveal that there would be no exceedances of NO2, RSP, FSP and SO2 criteria at all ASRs.  In fact, the predicted 1-hr NO2, 24-hr and annual RSP, 24-hr and annual FSP and 10-min and 24-hr SO2 concentrations are well below the respective criteria.

4.7.37              Higher pollutant concentrations of annual NO2 have generally been predicted at ASRs located adjacent to the existing road network near Lam Tei Interchange and junction between Tsing Lun Road and Tsz Tin Road.  The worst hit level is generally found at 1.5mAG, which are closest to tailpipe emissions along open roads.  In particular, the predicted cumulative annual NO2 concentrations at the following ASRs are greater than 36 µg/m3 (i.e. >90% of the AQOs):

·            R17 House no. 199A, Kei Lun Wai

·            R60 Block 6, 18 Rosewood

·            R61 Block 10, 18 Rosewood

·            P35 Block 1 SHR Site

4.7.38              It should be noted that this operation air quality impact assessment has adopted the territory wide emission inventory from PATH for Year 2020 for assessing the future background concentrations for Year 2029.  Hence, the predicted results are conservative.

4.7.39              A 50x50m grid is used to generate pollution contours. Contours of 19th highest 1-hour and annual NO2 concentrations, 10th highest 24-hour and annual RSP/FSP concentrations at the worst affected level (i.e. 1.5mAG) in Year 2029 are illustrated in Figure 4.73 to Figure 4.78. Contours of 4th highest 10-min and 24-hour SO2 concentrations at two worst affected levels (i.e. 1.5mAG and 30mAG) are shown in Figure 4.79 to Figure 4.82 Contour plots indicate that there is no exceedance at all sensitive uses.

4.7.40              As mentioned in Section 4.7.14, Year 2033 has also been taken as an additional assessment year to represent the worst case scenario with full population intake. The predicted maximum 1-hour and annual NO2 concentrations, 10th highest 24-hour and annual RSP/FSP concentrations in Year 2033 are presented in Table 4.17 and detailed in Appendix 4.18.

Note:

[1] Impact at worst affected height is presented for each ASR.

[2] SO2 impact in Year 2033 is same as Year 2029.

[3] Worst affected height is at 1.5mAG for all ASRs.

[4] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R09, R32, R65 as well as 15mAG for R59.

[5] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R59, R62-R65.

[6] Worst affected height is at 30mAG for all ASRs except at 30mAG for P33.

 

4.7.41              The results presented in Table 4.17 and Appendix 4.18 reveal that there would be no exceedances of NO2, RSP, FSP and SO2 criteria at all ASRs.  In fact, the predicted 1-hr NO2, 24-hr and annual RSP, 24-hr and annual FSP and 10-min and 24-hr SO2 concentrations are well below the respective criteria.

4.7.42              Similar to Year 2029, the worst hit level is generally found at 1.5mAG, which are closest to tailpipe emissions along open roads. When comparing to Year 2029, the predicted concentrations are generally lower with the exception of those ASRs in vicinity to planned roads that have not commissioned in Year 2029, such as the access roads of Hong Po Road Site and San Hing Road Extension School Sites. 

4.7.43              It should be noted that this operation air quality impact assessment has adopted the territory wide emission inventory from PATH for Year 2020 for assessing the future background concentrations for Year 2033.  Hence, the predicted results are conservative.

4.7.44              A 50x50m grid is used to generate pollution contours. Contours of 19th highest 1-hour and annual NO2 concentrations, 10th highest 24-hour and annual RSP/FSP concentrations at the worst affected level (i.e. 1.5mAG) in Year 2033 are illustrated in Figure 4.83 to Figure 4.88. Contour plots of SO2 in Year 2033 are same as Year 2029. Contour plots indicate that there is no exceedance at all sensitive uses.

Air Quality Implication due to the Recommended Direct Technical Noise Remedies

4.7.45              As mentioned in Section 4.7.17, proposed noise mitigation measures (i.e. direct technical noise remedies), namely noise barriers, have been taken into account in the operation air quality assessment. According to Appendix B, Clause 5(ix) of the EIA Study Brief, the air quality implication due to the recommended direct technical noise remedies shall be assessed. As such, an additional scenario without the proposed noise mitigation measures has been conducted for the worst assessment year (i.e. Year 2029). Results are summarized in Table 4.18 below with details presented in Appendix 4.19.

Note:

[1] Impact at worst affected height is presented for each ASR.

[2] Air quality implication due to the recommended direct technical noise remedies is determined by subtracting the maximum 19th highest 1-hour and annual NO2, and 10th highest 24-hour and annual RSP/FSP concentrations predicted under the “with scenario” across various assessment heights by those predicted under “without” scenario.

[3] Worst affected height is at 1.5mAG for all ASRs.

[4] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R09 and R65 as well as 15mAG for R59.

[5] Worst affected height is at 1.5mAG for all ASRs except at 10mAG for R62-R65.

[6] Worst affected height is at 1.5mAG for all ASRs except at 5mAG for R49.

 

 

4.7.46              As illustrated in Table 4.18, with the implementation of proposed noise mitigation, reduction of pollutant concentrations is generally predicted. The cumulative air quality impact at all ASRs for without the recommended direct technical noise remedies would also comply with the AQO. Adverse air quality impact during operation phase of the Project is therefore not anticipated.  The impact due to the updating of noise mitigation measures as mentioned in Section 4.7.18 should only have insignificant change to the modelled results.

Incremental Air Quality Impact

4.7.47              Pollutant contributions associated with the Project are generated from its induced traffic. The Project contribution in Year 2029 (i.e. worst assessment year) could be quantified by comparing the assessment results under “with” and “without” Project scenarios.

4.7.48              The assessment results in Year 2029 for both “with” and “without” Project scenarios are summarized in Table 4.19 to Table 4.24 below. The “With Project” scenario assumes all the proposed direct noise mitigation measures are in place.  Planned ASRs within the Site are not assessed since they are not present under the without Project scenario. Detailed results of the without Project scenario in Year 2029 are presented in Appendix 4.20.

Note:

[1] Impact at worst affected height is presented for each ASR, which is at 1.5mAG for all ASRs.

[2] Predicted annual FSP concentration at the same assessment height as those under “With Project “scenario is presented.

 

4.7.49              As illustrated in Table 4.19 to Table 4.24 above, the maximum total changes in annual NO2 on the representative ASRs are less than 1 μg/m3, while the maximum total changes in annual RSP and FSP concentrations are both less than 0.1 μg/m3. Maximum total changes in the cumulative 19th highest 1-hour NO2 concentration is 7 μg/m3, while the maximum total changes in the 10th highest 24-hour RSP and FSP concentrations both less than 0.1 μg/m3. The changes are considered relatively small when compared to the AQOs. The results indicated that the Project would not induce to adverse air quality impact on ASRs in Year 2029 (i.e. worst assessment year).

4.7.50              It is also noted that the above results are for Year 2029, which population intake has not taken place yet. In view of this, the Project contributions in Year 2033 (i.e. worst assessment year with full population intake) have also been quantified as shown in Table 4.25 to Table 4.30. The “With Project” scenario has assumed all proposed direct noise mitigation measures are in place. Detailed results of the without Project scenario in Year 2033 are presented in Appendix 4.21.

Note:

[1] Impact at worst affected height is presented for each ASR, which is at 1.5mAG for all ASRs.

[2] Predicted annual FSP concentration at the same assessment height as those under “With Project “scenario is presented.

 

4.7.51              As illustrated in Table 4.25 to Table 4.30 above, the maximum total changes in annual NO2 on the representative ASRs are less than 4 μg/m3, while the maximum total changes in both annual RSP and FSP concentrations are 0.1 μg/m3. Maximum total changes in the cumulative 19th highest 1-hour NO2 concentration is 20 μg/m3, while the maximum total changes in the 10th highest 24-hour RSP and FSP concentrations are both 0.2 μg/m3. The changes are considered relatively small when compared to the AQOs. The results indicated that the Project would not induce adverse air quality impact on ASRs even after full population intake in Year 2033 (i.e. worst assessment year with full population intake).

Recommended Mitigation Measures

4.7.52              According to the operation air quality assessment results, adverse cumulative air quality impact during operation phase is not anticipated.  No mitigation measures are required.

4.7.53              For the planned SHR SPS, the design shall house the processing equipment inside reinforced concrete structure and the foul air to be ventilated to a deodouriser with odour removal efficiency of 99.5% for treatment before discharge.  The ventilation outlet should be located away from the nearby ASRs as far as practicable.  The ventilation system shall also maintain a negative pressure within the facility.

4.7.54              For the future RCPs within the proposed housing sites, it is recommended that their siting should be away from the nearby ASRs as far as possible.  The design of the future RCPs should incorporate proper ventilation and deodourisng and exhaust system to minimize the potential odour nuisance on the nearby ASRs.  The ventilation and deordourising system shall be properly maintained.  In addition, the following good housekeeping measures shall be implemented:

·         immediate cleansing after each refuse collection operation would be put in place during the operation of the RCP;

·         the roller shutter of the vehicular access of the RCP would only be opened during access of refuse collection vehicles;

·         RCP including the roller shutter would be closed during other times; and

·         the refuse would not be stored overnight within the RCP, i.e. the refuse will be delivered to the landfill within a day to avoid accumulation of refuse within the RCP.

Residual Impact

4.7.55              No adverse air quality impact or odour impact during operation phase are anticipated. 

4.8                       Conclusion

Construction Phase Impact

4.8.1                  Potential construction dust impact would be generated from site clearance, land decontamination, site formation works and roadworks during the construction phase.  Quantitative construction dust impact has been assessed and the predicted cumulative air quality impacts on all ASRs would comply with the criteria stipulated in the EIAO-TM and the AQOs with the implementation of hourly watering at the works area.  Therefore, no adverse air quality impact during construction phase is anticipated.

Operation Phase Impact

4.8.2                  Quantitative operation air quality impact from vehicular emission associated with the Project and the existing and planned road network, and industrial emissions in the vicinity of the Project has been assessed.  The results concluded that the predicted cumulative air quality impacts on all ASRs would comply with the AQOs.  Therefore, no adverse air quality impact during operation phase is anticipated.

4.8.3                  With the installation of deodourising units with 99.5% odour removal efficiency and appropriate design measures at the proposed SHR SPS, and proper ventilation and deodorizing design system installed at the future RCPs together with implementation of good housekeeping, it is anticipated that there would be no adverse odour impact from the proposed SHR SPS and future RCPs at the nearby ASRs.
