4 Noise Impact

4.1 Introduction

4.1.1 Potential airborne noise impacts likely arise from both the construction and operation stages of the Project have been evaluated in this section. Recommendations on noise mitigation measures have also been made where necessary and appropriate.

4.2 Environmental Legislation, Standards, and Guidelines

General

4.2.1 Noise impacts have been assessed in accordance with Annexes 5 and 13 of the Technical Memorandum on Environmental Impact Assessment Process (TM-EIAO).

4.2.2 The Noise Control Ordinance, Cap. 400 (NCO) and Environmental Impact Assessment Ordinance, Cap. 499 (EIAO) provide the statutory framework for noise control. Assessment procedures and standards are set out in the following Technical Memoranda (TMs):

· Technical Memorandum on Environmental Impact Assessment Process (TM-EIAO);

· Technical Memorandum on Noise from Places other than Domestic Premises, Public Places or Construction Sites (TM-IND);

· Technical Memorandum on Noise from Construction Work in Designated Areas (TM-DA);

· Technical Memorandum on Noise from Construction Work other than Percussive Piling (TM-GW); and

· Technical Memorandum on Noise from Percussive Piling (TM-PP).

4.2.3 Percussive piling is governed under the TM-PP and a construction noise permit (CNP) is required in order to carry out such work. As the issuance of a CNP by the Noise Control Authority would depend on the compliance of percussive piling noise impact with the limits set out within the TM-PP, the assessment of this type of noise would not be covered in this EIA Report.

Construction Noise during Non-restricted Hours

4.2.4 Daytime general construction works (excluding percussive piling) between the 0700 – 1900 hours on weekdays, i.e. non-restricted hours, is controlled under the EIAO. Annex 5 of the TM-EIAO sets out the construction noise assessment limits, which are L_{eq(30 min)} 75 dB(A) for domestic premises, hotels and hostels; and L_{eq(30 min)} 70 dB(A) for schools during normal hours (65 dB(A) during examination periods) and all other places where unaided voice communication is required. The criteria are summarized in Table 4.1.

Table 4.1 Daytime Construction Noise Criteria

Uses	Daytime Noise Criteria, (Leq, 30min, dB(A))
Domestic premises, hotel, hostel	75
Educational Institution	70
Educational Institution (during examination)	65

Construction Noise during Restricted Hours

4.2.5 Between 1900 and 0700 hours and all day on Sundays and public holidays, activities involving the use of powered mechanical equipment (PME) for the purpose of carrying out construction work is prohibited unless a CNP has been obtained.  A CNP may be granted in cases where the noise can be contained within the Acceptable Noise Level (ANL) at the noise sensitive receivers (NSRs).  ANLs are assigned depending upon the Area Sensitivity Ratings (ASRs).  The corresponding basic noise levels (BNLs) for evening and night-time periods are given in Table 4.2.

Table 4.2 Construction Noise Criteria during Restricted Hours

Time Period	ANL During Restricted Hours (Leq, 30min, dB(A))
	ASR A	ASR B	ASR C
Evening (1900 to 2300 hours) ^(1)	60	65	70
Night-time (2300 to 0700 hours)	45	50	55

Note:

(1) Includes Sundays and Public Holidays during daytime and evening.

4.2.6 Despite any description or assessment made in this EIA Report on construction noise aspects, there is no guarantee that a CNP will be issued for the Project construction. The Noise Control Authority will consider a well-justified CNP application, once filed, for construction works within restricted hours as guided by the relevant TMs issued under the NCO. It will also take into account contemporary conditions/ situations of adjoining land uses and any previous complaints against construction activities at the site before deciding whether to grant a CNP.  Nothing in this EIA Report should bind the Noise Control Authority in making its decision.  If a CNP is to be issued, the Noise Control Authority should include in the permit any condition it thinks fit.  Failure to comply with any such conditions will lead to cancellation of the CNP and prosecution under the NCO.

4.2.7 Given that the Project is located outside the designated area as defined in Noise Control Designated Area Plan No. EPD/NP/NT-06, in which the control of Specified Powered Mechanical Equipment (SPME) and Prescribed Construction Work (PCW) will apply, noise assessment for SPME during construction phase would not be conducted in this EIA Report.

4.2.8 For maintenance trains depart and return to the SHD between 2300 and 0700 hours, these will be used to support maintenance operations in the transporting of personnel and plant for inspection and remedial works. The night-time noise from maintenance trains is governed by CNP under NCO and hence would not be quantified in this EIA study.

Operational Noise – Airborne Rail Noise

4.2.9 The TM-EIAO and TM-IND stipulate the appropriate ANL for airborne rail noise.  The ANLs are dependent on Area Sensitivity Ratings of the Noise Sensitive Receivers (NSRs) and are shown in Table 4.3.  The TM-EIAO also specifies the maximum rail noise limit of L_max 85 dB(A) between 2300 and 0700 hours, and the Hong Kong Planning Standards and Guidelines (HKPSG) specifies a 24-hour averaged noise level of 65 dB(A) L_eq,24hr.

Table 4.3 Acceptable Noise Levels for Airborne Rail Noise

Time Period	Noise Criteria (Leq, 30min, dB(A))
	ASR A	ASR B	ASR C
Daytime and Evening (0700 to 2300 hours)	60	65	70
Night-time (2300 to 0700 hours)	50	55	60

Operational Noise – Fixed Plant Noise

4.2.10 Fixed noise sources associated with the Project would be controlled by the NCO and TM-IND.  The ANL is a function of the type of area within which the NSRs are located, and the degree of the effect on the NSRs of influencing factors such as major roads and industrial areas.

4.2.11 More stringent criteria for planned fixed plant noise impact stipulated in the TM-EIAO for planning purposes are as follows.

· 5 dB(A) below the appropriate ANL set out in the TM-IND; or

· prevailing background noise level where the prevailing background noise level is 5 dB(A) below the appropriate ANL (i.e. ANL - 5dB(A)).

4.2.12 For the noise assessment for the existing fixed plant noise sources, ANL has been adopted as the assessment criteria for evaluation of noise impact. Cumulative fixed plant (i.e. planned and existing fixed plant noise sources impacts) noise impacts, as well as fixed plant noise plus railway noise impacts have respectively been assessed against ANL as stipulated in the TM-IND.

4.2.13 The ANLs for different time periods are given in Table 4.4. The noise criterion of adopting prevailing background noise level would generally apply to areas with low ambient noise levels such as rural or suburban areas. For areas with major nearby noise sources such as road and rail traffic, NSRs adjacent to these locations would be subject to ambient noise levels higher than the ANL.

Table 4.4 Acceptable Noise Levels for Fixed Noise Sources

Time Period	ANL, dB(A)			ANL-5, dB(A)
	ASR A	ASR B	ASR C	ASR A	ASR B	ASR C
Daytime and Evening (0700 to 2300 hours)	60	65	70	55	60	65
Night (2300 to 0700 hours)	50	55	60	45	50	55

4.3 Description of the Environment

4.3.1 The location of the Project is shown in Figure No. NEX1062/S/SHD/ACM/Z10/101. The Project site is situated on reclaimed land formed in the 1990s and adjoins North Lantau Highway (NLH) to south-east.

4.3.2 As discussed in Section 2.2, the planned land use within the Study Area is mainly for economic and housing development. The existing noise climate is dominated by the road traffic from North Lantau Highway (NLH); the rail noise from existing Tung Chung Line (TCL) and Airport Express Line (AEL); rail noise and fixed plant noise from the operation of existing SHD and the associated train movements on entry tracks; and the aircraft noise from aircraft approaching and departing from Hong Kong International Airport (HKIA).

4.3.3 Continuous free-field noise measurement was conducted at three locations within the existing SHD boundary from 30^th November to 1^st December 2016 to obtain prevailing background noise levels. The measurement locations are shown in Figure No. NEX1062/S/SHD/ACM/Z10/141. The noise measurements were conducted using B&K Type 2238 Sound Level Meter (Type 1) and were calibrated using B&K Sound Level Calibrator Type 4231 with a calibration signal of 94.0 dB(A) at 1kHz. The measurements were conducted with reference to the calibration and measurement procedures as stated in the TM-IND. The prevailing noise measurement results are summarised in Table 4.5 below. As the microphones were set in the free field condition, a façade correction of 3 dB has been applied to the noise measurement results.  

Table 4.5 Summary of Measured Prevailing Background Noise Level

ID	Measurement Location	Dominant Noise Source	Average Measured Noise Level*, Leq (30 min) dB(A)
			Daytime and Evening (0700 to 2300 hours)	Night-time (2300 to 0700 hours)
M01	Roof of Main Depot Building	Aircraft and SHD	61	59
M02	Roof of Main Depot Building	Aircraft and SHD	62	60
M03	Next to building AB11 Transformer Room (at ground level)	NLH, TCL & AEL	71	64

Note:

* A facade correction of 3 dB(A) has been included in the measurement results.

4.3.4 Based on the measurement results in Table 4.5, appropriate noise criteria for planned fixed noise sources were determined by comparing the prevailing background noise levels and the appropriate ANL-5 dB(A), as presented in Table 4.4. The proposed noise criteria for planned fixed noise sources are summarized in Appendix 4.1.

4.3.5 The existing SHD, TCL and AEL operation are considered as one of the dominant noise sources in the vicinity of Siu Ho Wan. With the implementation of SHD Replanning Works, the Reprovisioned SHD will be fully located under a continuous concrete slab, therefore the operation noise from Reprovisioned SHD will be minimized and the noise environment in Siu Ho Wan could be improved. Without the proposed replanning works, the operation noise arising from existing SHD as well as the noise environment remains unchanged.

4.3.6 The potential dis-benefit on noise environment would be the interim stages of Reprovisioned SHD with only partial facilities being operated under concrete slab while the existing SHD is still operating. Nevertheless, the depot replanning scheme has been carefully developed to minimize the potential noise impact on the SHD Topside Development. Details on the tentative depot replanning scheme are discussed in Section 2.4.

4.4 Noise Sensitive Receivers

4.4.1 According to the criteria set out in Annex 13 of TM-EIAO, observations from site visits and review of relevant land use plans including the Outline Zoning Plans (OZP), representative NSRs, both existing and planned NSRs, within 300m assessment area of the Project boundary have been reviewed. The assessment area has been agreed with the Director of Environmental Protection (the Director) before commencing the assessment.

4.4.2 Representative NSRs located closest to the subject noise sources, i.e. first layer of NSRs, are considered as the most affected locations.  Furthermore, the first layer of NSRs would provide acoustic shielding to those receivers at further distance behind.  The first layer of NSRs represents the worst-case scenario and are selected as representative NSRs for noise assessment.  

4.4.3 A summary of representative NSRs, including planned and existing NSRs, is presented in Table 4.6 with their locations shown in Figure No. NEX1062/S/SHD/ACM/Z10/140.

Table 4.6 Identified NSRs within 300m Study Boundary from the Project

NSRID	Description	Land Use	Existing/Planned NSR	No. of Storey	Approximate Distance to the boundary of the Project (m)
N01	Lantau North (Extension) Country Park^(1)	Country Park	Existing	N/A^(2)	220
N02	SHD Topside Development^(3)	Residential	Planned	15-22	Within the boundary of the Project

Notes:

(1) Photograph of existing NSR (i.e. Lantau North (Extension) Country Park) is shown in Figure No. NEX1062/S/SHD/ACM/Z10/140. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks.

(2) N/A - Not Applicable.

(3) According to the Clause 3.2.1(e) and Clause 4.2.1(e) of Appendix C of Study Brief (ESB-296/2016), the planning parameters and conditions together with constraints identified for the SHD Topside Development have been reviewed and agreed with relevant Government bureaux/departments, including Planning Department and Lands Department, under separate submission by the Project Proponent.

4.4.4 The construction of the SHD Topside Development would commence upon completion of respective concrete slab in each stage. The tentative years of population intake for the SHD Topside Development in each phase are shown in Appendix 2.6. As the construction of the concrete slab, as well as the operation of the Reprovisioned SHD facilities, will be carried out by stages (Table 2.4 refers), the SHD Topside Development would be subject to different noise impacts in different phases. Construction noise impact assessment has been considered according to the construction programme as provided in Appendix 2.4. For fixed plant and rail noise assessment, assessment scenarios have been derived based on the staging of SHD Repolanning Works and phasing of SHD Topside Development are presented in Table 4.7.

Notes:

(1) The foundation of SHD Topside Development including piling and excavation works will be conducted in parallel with replanning works respectively.

(2) Upon completion of concrete slab in respective staging area, the contractor(s) of SHD Topside Development would be on board to commence the superstructure works. The remaining SHD Replanning Works including architectural builders works and finishes (ABWF), electrical and mechanical (E&M) provision and track works will be conducted under the concrete slab. It is expected that there would be insignificant noise contribution from these remaining works as these works will be conducted under the deck and their nature of works are minor.

(3) Existing rail noise sources include the train movement on the stabling sidings and test track within the SHD, the entry tracks to the east and west of SHD and the mainline (i.e. TCL and AEL). As the Reprovisioned SHD will be located under the concrete slab and thus the railway noise contribution from train movement within the Reprovisioned SHD will be insignificant (Appendix 4.15 refers).

(4) NSRs located at more than 300m from the noise sources or with no direct line of sight to the noise sources would not be affected by the noise sources and thus they will not be selected for noise assessment. Details of selected NAPs are presented in Appendix 4.1.

(5) Not Applicable. Operation of existing SHD will be migrated to Stage 1 to 3 Reprovisioned SHD which is under concrete slab.

4.4.5 Representative noise assessment points (NAPs) for assessments of construction noise are listed in Table 4.8, while the NAPs identified for fixed plant noise and railway noise with the summary of noise criteria and detailed discussion on the selection of noise criteria presented in Appendix 4.1 respectively. The NSRs has been agreed with the Director prior to the commencement of the quantitative construction noise, fixed plant noise, and rail noise impact assessment.

4.5 Construction Phase

Source of Impact

4.5.1 Potential source of noise impact during the construction of the Project would be the use of Powered Mechanical Equipment (PME) for various construction activities. Major construction works would include the following activities:

· Demolition of existing depot facilities;

· Bored piling works, pile cap construction and excavation works related to the construction of SHD Topside Development;

· Pad footing foundation works;

· Construction of SHO and modification of existing AEL/TCL tracks; as well as local access roads and emergency vehicular access (EVA);

· Construction of concrete slab; and

· Reprovision of SHD facilities by stages.

4.5.2 Details of the proposed construction methods and sequence of works are described in Section 2 of this EIA Report. Construction stages that would have noticeable varying construction noise emissions at existing and planned NSRs at the assessment area have been agreed with the Director before commencing the construction noise impact assessment. The tentative programme for SHD replanning works will be implemented in four stages, tentatively from 2019 to 2036, as summarized in Table 4.9 below.

Table 4.9 Tentative Programme for SHD Replanning Works

Stage	Tentative Works Programme	Operation Year of Respective Staging of Reprovisioned SHD
1	2019 – 2024, with concrete slab completed in 2023	2024
2	2024 – 2028, with concrete slab completed in 2026	2028
3	2028 – 2032, with concrete slab completed in 2030	2032
4	2032 – 2036, with concrete slab completed in 2034	2036

4.5.3 The construction of SHO will be conducted in parallel with Stage 1 SHD Replanning Works, i.e. from 2019 to 2024. Civil construction works for SHO will be completed in 2024 while building services (BS) and electrical and mechanical (E&M) works will be conducted between 2024 and 2026. Operation of SHO would commence in 2026.

4.5.4 The tentative programme as shown in Table 4.9 are established based on the construction works to be conducted during non-restricted hours (i.e. 0700 – 1900 hours on any days other than general holiday), while the modification of existing AEL/TCL tracks and the works that would be conducted in proximity to the live tracks (e.g. installation of excavation and lateral support in excavations next to live track, erection of prefabricated steel trusses, precast beams, crash desks and protective barriers and hoardings, etc.) should be conducted during restricted hours (i.e. the time between 1900 and 0700 hours and any time on a general holiday) in order to avoid disruption or interruption to the normal operation of existing AEL and TCL. However, neither existing nor planned NSRs are located within 300m boundary from modification of existing track works to be completed in Stage 1 SHD Replanning Works. As such, it is anticipated that there would be no unacceptable noise impact from the proposed works in proximity to the live track. A CNP should be obtained for the use of PMEs within the restricted hours from the Noise Control Authority prior to commencement of the relevant construction works.

4.5.5 Noise from maintenance trains departing and returning to the existing and the Reprovisioned SHD between 2300 and 0700 hours will be governed by a CNP under NCO, and hence the associated construction noise impact would not be evaluated in this EIA study.

Assessment Methodology

4.5.6 The methodology for the noise impact assessment is in accordance with the procedures outlined in the TM-GW. The general approach is summarized below:

· Locate the NSRs which would most likely be affected by noise from the construction work;

· Determine the items of PME for each discrete construction activity, based on available information or agreed plant inventories;

· Assign sound power levels (SWLs) to the proposed PME according to the TM-GW or other sources;

· Calculate distance attenuation to NSRs from notional noise source;

· Apply corrections in the calculations such as potential screening effects and acoustic reflection, if any;

· Predict construction noise levels at NSRs in the absence of any mitigation measures;

· Consider cumulative impact from concurrent projects within 300 m of the NSRs, if any; and

· Compare the cumulative construction noise level against the noise criteria and propose suitable mitigation measures where necessary.

4.5.7 SWLs of the equipment are made reference from Table 3 of TM-GW and "Sound power levels of other commonly used PME" (Other PME) published by EPD.  Where no relevant SWL to be found in the TM-GW and other PME, reference is made to Quality PME (QPME) available in EPD web site^[1].   The SWL of plant inventory as adopted in the unmitigated construction noise assessment is presented in Appendix 4.2.

4.5.8 The works programme and plant inventory for each stage of SHD Replanning Works, as presented in Appendices 2.4  and 4.2 respectively, were developed by the Preliminary Design Consultants of the Project Proponent.  The proposed plant inventory has been confirmed as being practical and adequate for completing the works within the scheduled timeframe.

4.5.9 It is assumed that all PME items required for a particular construction activity will be located at the notional or probable source position of work fronts where such activity is to be performed.  The locations of work fronts with respective NSRs are shown in Figure Nos. NEX1062/S/SHD/ACM/Z10/142 to NEX1062/S/SHD/ACM/Z10/145. The assessment has been conducted based on the cumulative SWL of PME likely to be used for each work front, taking into account the construction period in the vicinity of the receiver location.  To predict the noise level, PME has been divided into groups required for each discrete construction works task. The objective is to identify the worst case scenario representing those items of PME that would be in use concurrently at any given time. The sound pressure level (SPL) of each construction task was calculated, depending on the number of plant and distance from receivers. The noise levels at NSRs are then predicted by adding up the SPLs of all concurrent construction tasks from the Project and other concurrent projects identified during the course of the EIA study within the assessment area. Noise sources located at more than 300m from the selected assessment points are excluded from the assessment.

4.5.10 A positive 3 dB façade correction has been added to the predicted noise levels to account for the facade effect at each assessment point. The unmitigated construction noise impacts at the identified NSRs are predicted accordingly. Practicable direct mitigation measures including use of quieter equipment, movable barriers, enclosures and quieter alternative methods have been proposed where applicable if exceedance of relevant criteria would be predicted. In case where the mitigated noise levels still exceeded the relevant criteria, duration of the noise exceedance would be estimated.

Construction Noise Impact

Unmitigated Construction Noise Impact

4.5.11 For normal daytime working hours, exceedances of the construction noise criteria (L_{eq (30 min)} 75 dB(A) for residential uses and 70 dB(A) for educational institutions (65 dB(A) during examinations)) are predicted at representative NAPs with no mitigation measures in place. Details of the unmitigated construction noise calculations and results for different stages are presented in Appendix 4.3.

4.5.12 A summary of the unmitigated construction noise levels at the representative NSRs during normal daytime working hours is presented in Table 4.10. With the prediction of noise exceedance, noise mitigation measures are required to alleviate the construction noise impact to the affected NSRs for compliance with the noise limit.

Notes:

(1) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse construction noise impact is anticipated.

(2) Bold value denotes exceedance of noise criteria of 75 dB(A) for residential premises.

4.5.13 Based on the assessment results, there would be noise exceedances in the range of 2 to 11 dB(A) predicted at the NSRs under unmitigated scenario. Without any mitigation measures, the total number of dwellings exceeding the noise criterion set in Annex 5 of the TM-EIAO is estimated to be about 3,374.

Mitigation Measures

4.5.14 The construction noise assessment results indicate that, in the absence of any mitigation measures, there would be exceedance of the construction noise criteria at some of the NSRs. Various mitigation options listed below have thus been considered:

· Good site practices to limit noise emissions at the sources;

· Use of quiet powered mechanical equipment (PME); and

· Use of construction noise barriers or enclosures to screen noise from construction plant.

4.5.15 The above mitigation measures would be implemented in work sites as good practices where appropriate. Detailed descriptions of these mitigation measures are given in the following sections.

Good Site Practice

4.5.16 Although the noise mitigation effects are not easily quantifiable and the benefits may vary with site conditions and operating conditions, good site practices are easy to implement and do not impact upon the works schedule. The site practices listed below should be followed during each phase of construction:

· Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction program;

· Silencers or mufflers on construction equipment should be utilised and should be properly maintained during the construction program;

· Mobile plant, is any, should be sited as far from NSRs as possible;

· Machines and plant (such as trucks) that may be in intermittent use should be shut down between work periods or should be throttled down to a minimum;

· Plant known to emit noise strongly in one direction should, wherever possible, be orientated so that the noise is directed away from the nearby NSRs; and

· Material stockpiles and other structures should be effectively utilised, wherever practicable, in screening noise from on-site construction activities.

4.5.17 To reduce the noise impacts at the affected NSRs during normal daytime working hours, mitigation measure such as adopting quiet PME is recommended. The type of quiet PME adopted in this assessment is for reference only. The contractors may adopt alternative quiet PME as long as the proposed alternative PME would not result in construction noise impacts worse than those predicted in this assessment.

4.5.18 For the use of quiet plant associated with the construction works, reference has been made to QPME list available on the EPD website, which contains the SWLs for specific QPME. Whilst it is generally considered too restrictive to specify that the Contractor has to use specific models or items of plant, it is reasonable and practicable to propose plant noise performance specifications for specific PME so that some flexibility in selection of plant is allowed. The plant inventory for mitigated scenario and SWLs adopted for noise assessment are detailed in Appendix 4.4.

Construction Noise Barrier and Enclosure

4.5.19 To alleviate the construction noise impact on the affected NSRs, construction noise barriers or enclosures would be erected to provide screening from the construction plant.

4.5.20 Noise barriers will become more effective when located immediately adjacent to the working area, and can reduce the noise level by up to 5 dB(A) and 10 dB(A) for mobile and stationary plants, respectively.  The Contractor shall be responsible for design of the noise barrier with due consideration given to the size of the PME and the requirement of intercepting the line of sight between the NSRs and PME.  The minimum surface density of the movable noise barrier is 10 kg/m².

4.5.21 The use of full enclosure has been considered in this assessment to shelter relatively static plant such as air compressor, generator, concrete pump and grout mixer. These enclosures could provide about 15 dB noise attenuation. The typical configurations of noise barrier and enclosure are shown in Appendix 4.5.

4.5.22 The use of noise barrier and enclosure for various items of PME adopted for noise assessment are detailed in Appendix 4.4.

Mitigated Construction Noise Levels

4.5.23 With the implementation of the above proposed mitigation measures, the mitigated noise levels at the representative planned NSRs would be in the range of 50 – 75 dB(A), complying with noise limit of 75dB(A). The predicted construction noise levels at the representative NSRs are summarised in Table 4.11 and the detailed mitigated noise assessment results are presented in Appendix 4.6.

Cumulative Construction Noise Impact

4.5.24 According to the approved EIA report for Tung Chung New Town Extension (Register No. AEIAR-196/2016) and the EIA report for SHD Topside Development, the country Park and the planned NSRs of SHD Topside Development will experience cumulative construction noise impact from following concurrent projects:

· Construction works from the SHD Topside Development;

· Construction of Road P1 (Tung Chung – Tai Ho Section); and

· Construction of sewerage network.

4.5.25 Cumulative noise levels at the representative NAPs have been evaluated with results summarized in Table 4.12. Detailed calculation is presented in Appendix 4.7. It is predicted that the cumulative construction noise levels arising from the construction of the Project and other committed projects would comply with noise criteria set in the TM-EIAO.

However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse construction noise impact is anticipated.

(2) The construction noise impact arising from the Project would be insignificant and the cumulative mitigated construction noise impact would solely contribute from the concurrent projects.

Evaluation of Residual Construction Noise Impacts

4.5.26 With the implementation of the recommended noise mitigation measures and use of QPME, the predicted noise levels due to the construction of the Project would comply with the noise criteria.  

4.6 Operational Phase

4.6.1 As shown in Table 4.7, the SHD Topside Development will be subject to different types of noise impact in each stage of SHD Replanning Works and remaining activities in existing SHD.

4.6.2 As discussed in Section 2.1.2, the existing SHD is delineated as railway area under Railway Area Plan (RAP) which also covers AEL and TCL. The RAP was deposited in the Land Registry on 25 March 1994 under section 3 of the Mass Transit Railway (Land Resumption and Related Provisions) Ordinance (Cap 276). The existing SHD operates since 1998 for supporting the operation of existing TCL, AEL and DRL. Rolling stock (i.e. passenger trains, engineering maintenance trains, etc.) running on rail alignment within SHD is classified as railway noise source. The facilities, equipment, workshops and louvres for supporting the operation of existing/Reprovisioned SHD are considered as fixed plant noise sources. Noise assessments have been conducted based on the best available information on the location of the planned/reprovisioned fixed plant noise sources.

4.6.3 A Base Scheme, which accommodates 52 numbers of Type A building blocks and 56 numbers of Type B building blocks, of SHD Topside Development was considered during the early design development and has been progressively refined and eventually evolved as the Modified Scheme of SHD Topside Development to abate various environmental constraints as well as to avoid and minimize environmental impacts as much as practicable.

4.6.4 To minimise the road traffic and rail noise impacts, a Modified Type B building layout is proposed. The main difference between Type B building blocks and Modified Type B building blocks is that Modified Type B building blocks would have some of the noise sensitive windows specially designed to reduce the view angle overlooking onto both NLH / TM-CLK Link and TCL / AEL, and consequently reducing the associated road traffic and rail noise impacts respectively. The Modified Scheme of SHD Topside Development was therefore replaced some of the Type B building blocks by Modified Type B building blocks at some locations including Blocks 149, 401, 403 and 407 to address the adverse road traffic noise impact.

4.6.5 To address adverse rail noise impact, the feasibility of noise canopies of 15m wide along the southern podium edge (at +23 mPD) and the effectiveness of installing the noise canopy has been reviewed. It is noted that the extent of noise canopy is limited by the following safety and technical constraints:

· the need for smoke extracting strategy for staged development of the depot area;

· the need for smoke extracting strategy for SHO and PTI located at Phase 1 development;

· the practicability of routing smoke exhaust of depot area at about +17.1mPD to above +23 mPD (i.e. incompatibility with Emergency Vehicular Access (EVA), technical constraints in erecting exhaust at +23mPD before podium construction) to provide continuous noise canopy;

· the suitability of routing smoke exhaust of depot area above podium at +26.5mPD (i.e. visual impact, nuisance during routine testing and technical constraints in erecting exhaust at +26.5mPD before podium construction).

4.6.6 The proposed depot smoke discharge outlets will be arranged as far as practicable to prevent discharge under cover and that shall be further reviewed during detailed design stage. Potential concerns on smoke spilling into depot under a train fire at AEL/TCL mainline will also need to be followed up during detailed design stage with relevant authorities.

4.6.7 Throughout the rail noise assessment, the effectiveness of installing a 15m wide canopy along the southern podium edge (Figure 4.1c of Appendix 4.18) has been considered. However, the extent of noise canopy would be limited by the extent of podium to be built at that time.

4.6.8 For Phase 1 SHD Topside Development, Phase 1c development is not constructed at that time and hence it is not possible to extend the length of the noise canopy beyond the podium of Phase 1a and some sections of 15m wide noise canopy cannot shield the TCL / AEL as the alignment of TCL / AEL does not run parallel along southern podium edge. Hence, it is necessary to consider adopting the Modified Type B building blocks at Blocks 117, 139 and 140 to reduce the rail noise impacts as illustrated in Figure 4.1b of Appendix 4.18. Also, the provision of canopy at the podium of Phase 1a alone is not sufficient to protect the NSRs in Block 118 before provision of noise canopy at the podium of Phase 1c, Modified Type B building block is also recommended for Block 118.

4.6.9 Given that the setting of Phase 2 SHD Topside Development (Type A building blocks) will be protected by self-protecting blocks for the first row of residential blocks (Type B building blocks fronting AEL / TCL) and noise canopy at Phase 1 SHD Topside Development, all the planned NSRs in this phase would comply with respective noise criteria.

4.6.10 Similar to Phase 1 to Phase 2 SHD Topside Development, with the self-protecting blocks fronting AEL / TCL and noise canopy at Phase 1 SHD Topside Development, all the planned NSRs in Phase 3 SHD Topside Development would comply with respective noise criteria.

4.6.11 For Phase 4 SHD Topside Development, result indicates that most of the planned NSRs except Block 404 would comply with the respective noise criteria. Similar to Phase 1 SHD Topside Development, two sections of noise canopy at +23 mPD is recommended along podium of Phase 4 SHD Topside Development to address the consideration of smoke extracting strategy. However, 15m wide noise canopy cannot fully shield the TCL / AEL as the alignment of TCL / AEL does not run parallel along southern podium edge, and thus Block 404 would be exposed to rail noise levels exceeding the noise criterion by 5dB(A). Hence, it is necessary to adopt the Modified Type B building block at Block 404 for reduction of rail noise impacts.

4.6.12 Based on the above review, Modified Type B building blocks are proposed for Blocks 117, 118, 139, 140 and 404 as illustrated in Figure 4.1b of Appendix 4.18 for addressing rail noise. Nevertheless, other than these blocks, some blocks including Blocks 104, 111, 114, 116, 136 and 146 that would be exposed to rail noise levels with 5dB(A) less than the statutory criteria has been proactively adopted Modified Type B building blocks. During the subsequent detailed design stage of SHD Topside Development, the adoption of Modified Type B building blocks would be further reviewed as appropriate.

4.6.13 The stabling tracks and the test track of the Reprovisioned SHD, as well as TCL/AEL operation, are all at-grade tracks without structural integration with the building structure of SHD Topside Development, hence vibration transmission through structural elements of building to the planned NSRs is not anticipated. In addition, relevant mitigation measures for structural-borne fixed plant noise would be installed with reference to Good Practices on Ventilation System Noise Control to minimise structural-borne noise impact. It is therefore expected that there would be no structural-borne noise from railway and fixed plant noise sources from the Reprovisioned SHD affecting the SHD Topside Development.

Stage 1 SHD Replanning Works

4.6.14 During Stage 1 SHD Replanning Works (i.e. between 2019 and 2024 with concrete slab completed in 2023), no planned NSRs (population intake in 2026 in Phase 1 of SHD Topside Development) would be affected by the operation of existing SHD, and thus no operational noise assessment was conducted for this stage. The only existing NSR, Lantau North (Extension) Country Park, located at about 220m from the SHD would be subject to existing noise environment due to the operation of SHD.

Stage 2 SHD Replanning Works (Assessment Scenario 1A,1B &1C)

Source of Impact - Fixed Plant Noise

4.6.15 Site surveys were conducted on 29 June and 8 December 2016 in the existing SHD to identify the fixed plant noise sources associated with the existing operation of SHD. A list of concerned existing fixed plant noise sources with existing SHD and planned fixed plant noise sources for supporting the operation of Stage 1 Reprovisioned SHD & SHO is presented in Table 4.13 and shown in Figure No. NEX1062/S/SHD/ACM/Z10/146.

Source of Impact – Airborne Railway Noise

4.6.16 It is expected the worst case in the railway noise impact to the SHD Topside Development would occur in Stage 2 SHD Replanning Works with Phase 1 SHD Topside Development being occupied. As shown in Figure Nos. NEX1062/S/SHD/ACM/Z10/150 to NEX1062/S/SHD/ACM/Z10/152, existing railway noise sources during Stage 2 SHD Replanning Works that would affect the SHD Topside Development include the train movement within the existing SHD in Stage 3 and 4 areas and on the mainline including the re-aligned TCL & AEL, as well as the test track and entry tracks located immediately to the east and west of SHD. For the potential railway noise from train movements within Reprovisioned SHD under podium deck, there would be negligible noise contribution as shown in Appendix 4.15 and therefore it would not be included in the detailed noise assessment in Assessment Scenario 1 as well as other scenarios.

(2) The location of the fixed plant source may be changed subject to the detailed design.

(3) The planned fixed plant will support the operation of Reprovisioned SHD and SHO.

Source of Impact - Airborne Railway Noise

4.6.20 Upon completion of Reprovisioned SHD (Figure Nos. NEX1062/S/SHD/ACM/Z10/156 to NEX1062/S/SHD/ACM/Z10/161 refer), train movements within the Reprovisioned SHD will be fully under the concrete slab and thus the railway noise from train movements within Reprovisioned SHD will be insignificant. The railway noise source that would affect the SHD Topside Development is the train movement on mainline including the realigned TCL&AEL.

Assessment Methodology

Fixed Plant Noise

4.6.21 The SWLs of fixed plant noise sources within the existing SHD has been evaluated according to the on-site noise measurement. Sound pressure level at the selected assessment points has been calculated according to the following equation:

SPL = SWL – DC + FC – BC

where

SPL	Sound Pressure Level, in dB(A)
SWL	Evaluated Sound Power Level based on on-site measurement, in dB(A)
DC	Distance Attenuation, in dB(A) (i.e. 20 log D + 8 [where D is the distance in metres])
FC	Facade Correction, in dB(A) (i.e. 3 dB(A))
BC	Barrier Correction, in dB(A)

4.6.22 For the assessment of noise from planned fixed plant noise sources for the Reprovisioned SHD and SHO, the maximum permissible sound power levels (Max. SWLs) of the identified fixed noise sources have been determined by adopting standard acoustic principles. The following formula has been used for calculating the maximum SWLs of the fixed plant.

SPL (ANL – 5) = Max. SWL – DC + FC + TC +RC – BC

where

SPL	Sound Pressure Level, in dB(A)
Max. SWL	Maximum Permissible Sound Power Level, in dB(A)
DC	Distance Attenuation, in dB(A) (i.e. 20 log D + 8 [where D is the distance in metres])
TC	Tonal Correction, in dB(A) (assumed 3 dB(A) for planned louvers for conservative assessment)
RC	Reverberation Correction, in dB(A) (i.e. 3 dB(A) to account for the reverberant nature of the planned/reprovisioned fixed plant sources located under the concrete deck only)
FC	Facade Correction, in dB(A) (i.e. 3 dB(A))
BC	Barrier Correction, in dB(A)

4.6.23 With reference to MTR’s depot ventilation system design for Reprovisioned SHD and SHO, the ranges of maximum SWL of planned louvers are summarized in Table 4.16. Fixed plant noise impact assessment has been conducted based on the upper limit of the max. SWL in each group of louver (e.g. 85 dB(A) and 75 dB(A) for Group A louvre for daytime/evening and night-time respectively).

Table 4.16 Groups of Ventilation Louvre

Group	Max. SWL during Daytime/ evening, dB(A)	Range of Max. SWL during night-time, dB(A)
A	81-85	71-75
B	86-90	76-80
C	91-95	81-85
D	96-100	86-90
E	101-105	91-95
F	106-110	96-100
G	75-85	75-85

4.6.24 The cumulative noise impact from existing fixed plant noise sources and planned ventilation louvres has been predicted based on standard acoustic principles to check the noise compliance with ANL.

4.6.25 It is assumed that all the fixed plant within the same location would be operated at the same time as worst case scenario. Screening correction offered by buildings, podium or other substantial structures was taken into account in calculating the predicted noise levels. In the case that NSR has no direct line of sight to the noise source, -5 dB(A) barrier correction has been applied as conservative approach. If the NSR is located deep inside the shadow zone of the screening structure and the barrier correction of greater than -5 dB(A) is expected, barrier attenuation has been calculated in accordance with ISO 9613 – 2 Acoustics – attenuation of sound during propagation outdoors – Part 2: General method of calculation. The equation (14) of ISO 9613-2 for calculating the barrier attenuation D_z is extracted and shown below:

C2	is equal to 20, and includes the effect of ground reflections; if in special cases ground reflections are taken into accounted separately by image source, C2 = 40;
C3	is equal to 1 for single diffraction ; C3 = [ 1+(5λ/e)^2] / [(1/3) + (5λ/e)^2] for double diffraction
λ	is the wavelength of sound at the nominal midband frequency of the octave band in metres
z	is the difference between the pathlengths of diffracted and direct sound, as calculated by equations (16) and (17) of ISO 9613-2, in meteres;
Kmet	is the correction factor for meteorological effects, given by equation (18) of ISO 9613-2
e	is the distance between the two diffraction edges in the case of double diffraction

4.6.26 Schematic drawing that illustrates the calculation of path difference (z) is shown in Appendix 4.8.

4.6.27 The nominal midband frequency of the octave band for various fixed plant items in existing SHD was measured and is summarized in Table 4.17.

Table 4.17 Measured Nominal Midband Frequency of Fixed Plant Items

Fixed Plant Items	Fixed Plant Items ID.	Nominal Midband Frequency, Hz
Louvres at Main Depot Building	MD_SS_1, MD_SS_2, MD_SS_3, MD_CP_1, MD_CP_2, MD_CP_3, MD_CP_4, MD_MW_1, MD_MW_2, MD_MW_3, MD_MW_4	200 Hz to 1k Hz
Louvres at AB3 Substation	AB3_1 & AB3_3	200 Hz to 500 Hz
Locomotive Repair Facility (AB6)	AB6_1 & AB6_2	315 Hz to 630 Hz
Air Conditioning units	ACC	500 Hz
Air handling units	AHU	630 Hz
Rail Grinder	RG	800 Hz
Maintenance activities via entrance area	MD_VH	2.5k Hz
Existing Wheel Lathe Machine	AB22	400 Hz to 2k Hz
Train Wash (East)	TWF_1	800 Hz to 1K Hz
Rail Milling Machine	RM	500 Hz to 630 Hz

4.6.28 For conservative purpose, the lowest measured midband frequency has been adopted for calculation the barrier attenuation Dz. Nominal midband frequency of 200 Hz and 315 Hz is adopted for planned louvres and new planned fixed plant items (i.e. Cooling Tower Plant for support the operation of Reprovisioned SHD and SHO) respectively.

4.6.29 Corrections of intermittency or impulsiveness were not included in the assessment as no known fixed plant sources to be used in SHD would produce impulsive and intermittent character. Tonality correction of 3 dB(A) was included in the assessment for conservative purpose. However, if the noise exhibits characteristics of tonality, intermittency or impulsiveness during the commissioning test, the noise limit should be reduced in accordance with the recommendation given in Section 3.3 of TM-IND.

4.6.30 Cumulative noise levels at NSRs are then be predicted by adding up the noise impact arising from fixed plant sources from the Project, fixed plant sources provided for SHD Topside Development and other concurrent projects identified during the course of the EIA study within the assessment area.

Operational Noise – Airborne Railway Noise Associated with SHD Operation

4.6.31 A computational model, CadnaA (version 4.1) developed by Datakustik GmbH from Germany, has been used to predict and assess the propagation of airborne train noise from train movements within SHD. The modelling methodology for propagation is based on the prediction procedures in Calculation of Railway Noise 1995 (CRN). The track is divided into segments and the noise level of each segment is eventually integrated into the overall noise level of the whole railway tracks. The input parameter in CRN is the train noise source term sound exposure level (SEL) at a distance of 25m from the nearside railhead. The L_Aeq is then deuced by CadnaA according to CRN from the train noise source term sound exposure level (SEL). The noise model has been validated by rail noise measurement as detailed in Appendix 4.12. The proposed methodology and computational model has been agreed with the Director prior to the commencement of the rail noise impact assessment.

4.6.32 By calculation in CadnaA model, the CRN emission noise levels were obtained in terms of Leq,30min for noisiest 30 minutes in daytime and night-time as well as Leq,24hr . The calculations are based on the following equation:

Leq,_{30min day(25m)} = Leq,_{1hr day(25m)} = SEL_25m + 10₁₀ log (N_day) – 10₁₀ log (60 x 60)

where

Nday	Double of number trains frequency in 30 minutes in day time

Leq,_{30min night(25m)} = Leq,_{1hr night(25m)} = SEL_25m + 10₁₀ log (N_night) –10₁₀ log (60 x 60)

where

Nnight

Double of number trains frequency in 30 minutes in night time

Leq,_24hr(25m) = 10₁₀log{[16 x 10^(Leq,_{1hr day(25m)}/10) + 8 x 10^(Leq,_{1hr night(25m)}/10)]/24}

4.6.33 The CRN calculation of noise level at NSRs is based on the following equation:

Leq_(NSR) = Leq_(25m) + Cdist + Cair+ Cgnd+ Cball+ Cscrn+ Cangl+ Crefl

where

Cdist	Distance correction (dB)
Cair	Air absorption correction (dB)
Cgnd	Ground correction (dB)
Cball	Correction for ballast track(dB)
Cscrn	Screening correction (dB)
Cangl	Angle of view correction (dB)
Crefl	Reflection correction (dB)

4.6.34 The Lmax is calculated using the standard acoustic principles with reference to the literature of “P.M. Nelson, Transportation Noise Reference Book, 1987”. The conversion between Lmax and SEL (single train event) is based on the following equation:

L_max = SEL – 10 log₁₀(L/V) – 10.5 + 10 log₁₀ {[4D/(4D²+1)] + 2 tan^-1 [1/(2D)]}

where

L	Train Length, in m
V	Train Speed, in km/h
d	Perpendicular distance from track, in m
D	d/L

Operational Noise – Airborne Railway Noise from Realigned Mainline (TCL/AEL) Operation

4.6.35 An in-house computational model as developed by Ove Arup & Partners Hong Kong Ltd (Arup) that compliant with CRN was used to predict and assess the propagation of train noise from mainline operation. Details of rail noise impact assessment methodology for mainline operation is presented in Appendix 4.9. The modelling methodology for propagation is based on the prediction procedures in CRN and it has been validated against the examples listed in CRN handbooks. According to Clause 4.1 of Appendix C of Study Brief, the computational model has been agreed with EPD prior to the commencement of the assessment. Model validation is given in Appendix 4.12. The proposed methodology and computational model has been agreed with the Director prior to the commencement of the rail noise impact assessment.

4.6.36 The assumptions adopted in the noise models for operation of SHD and realigned Mainline are summarized in Table 4.18.

Note:

(1) Reference was made from Northshore Lantau Development Feasibility Study – Environmental Impact Assessment (Register No.: AEIAR-031/2000) (NLDFS EIA) and Construction of an International Theme Park in Penny’s Bay of North Lantau and its Essential Associated Infrastructure (Register No.: AEIAR-032/2000). Noise level was corrected to 25m at 135kph for 1-car according to the Equation 15.21 in Transportation Noise Reference Book, 1987.

(2) On-site measurement was conducted to review the noise generation from the shunting trains. Details of train noise measurement are presented in Appendix 4.11. Airport Express Line (AEL) and Tung Chung Line (TCL) trains are same train type from the Spain manufacturer Adtranz-CAF since opening of AEL and TCL in 1998. A correction factor (10 log (10/8)) has been adopted to estimate the SEL of 10-car train. Based on the on-site train noise measurement results, the SEL of DRL shunting is lower than the SEL of TCL/AEL shunting by about 7dB(A). As a worst case scenario, the railway noise impact due to passenger train movement is predicted by using the highest SEL (i.e. 89dB(A)) among passenger trains on DRL, TCL and AEL. The maximum train speed of shunting train and engineering train within SHD is 22kph.

(3) Train frequencies on AEL and TCL have been confirmed by MTRCL.

(4) Operation scenarios due to replanning works to be carried out in stages have been developed and a worst case scenario has been adopted to evaluate the potential noise impact from the operation of existing SHD to SHD Topside Development.

(5) There would be no correction to the ballast track (i.e. Cball = 0) as the noise measurement of the source term was conducted for the trains running on the ballast track.

(6) Absorptive panel would be installed under platform of SHO as far as possible to prevent noise reflection.

Note:

(1) The planned noise sources include planned ventilation louvres and planned /reprovionsed fixed plants for supporting the operation of Reprovisioned SHD and SHO.

(2) The fixed plant noise impact associated with the planned fixed plant from SHD Topside Development (i.e. the concurrent project).

(3) The cumulative fixed noise sources impact associated with the operation of the proposed project and the concurrent project.

(4) N N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse fixed plant noise impact is anticipated.

(5) No night-time operation is assumed for kindergarten.

(6) The predicted noise level less than 20 dB(A) is considered negligible.

4.6.46 The assessment result indicated that the fixed plant noise impact for Scenario 4 would comply with the noise criteria set out in TM-EIAO and TM-IND. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse fixed plant noise impact is anticipated.

Assessment Scenario 1 to 4 - Rail Noise

4.6.47 As presented in Table 4.7, the SHD Topside Development will be subject to railway noise impact in different stage of SHD replanning works. Based on the proposed assessment methodology and the assumptions presented in Table 4.18, the unmitigated railway noise levels have been predicted and are summarized in Tables 4.25 to 4.30. Details of results are presented in Appendix 4.16.

4.6.48 For TCL/AEL operation, the SEL of 1 car (AEL/TCL train) at 135kph and 25m is 83.9dB(A) (Table 4.18 refers). Equation 15.21 in the Transportation Noise Reference Book 1987 has been adopted, with inclusion of façade correction, to calculate L_max at NSRs. The calculated L_max at different NSRs are provided in Appendix 4.17.

4.6.49 For depot train operation, the worst case (i.e. Assessment Scenario 1A to 1C), has been considered to evaluate the train noise in term of L_max due to the train movement within existing SHD. The nearest NSR at Block 149 (NAP 149-04) is taken as worst affect NSRs for the L_max train noise assessment. The horizontal distance from Block 149 to the nearest track is 28m. The predicted L_max at NAP 149-04 is 81dB(A) and 82dB(A) due to passenger trains and Engineering trains respectively. The predicted L_max at the nearest NSR (i.e. Block149) comply with the TM-EIAO noise criteria of 85dB(A), and thus it is anticipated that the L_max noise level at all NSRs of the SHD Topside Development would also meet the limit. Details of calculation are provided in Appendix 4.17.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

4.6.50 Exceedances in the range of 1 to 7 dB(A) are predicted at some representative NAPs at Phase 1 SHD Topside Development in Assessment Scenario 1A to 1C due to cumulative rail noise arising from SHD train movement and mainline operation, while the predicted exceedance of 1 to 7 dB(A) predicted at Phase 1, 3 & 4 SHD Topside Development in Assessment Scenario 2 to 4 are due to mainline operation only. Mitigation measures should be adopted to abate the railway noise impact. Without any mitigation measures, it is predicted that a total of about 200 dwellings will be exposed to rail noise impact under unmitigated scenario in Scenario 1A; 200 dwellings in Scenario 1B; 400 dwellings in Scenario 1C, 400 dwellings in Scenario 2, 400 dwellings in Scenario 3 and 400 dwellings after full occupation.

Mitigation Measures

Rail Noise

4.6.51 As discussed in Section 2.3, the existing built and operating areas at SHD are highly constrained by tracks, main depot building and maintenance facilities with minimal spacing. There are limited space at the existing operating areas next to stabling tracks, and the area between tracks and main depot building for provision of temporary noise barrier or enclosure which would involve construction of substantial steel structures and foundations. Therefore it is impractical to have temporary noise mitigation structures constructed along the stabling tracks for mitigation of potential noise impacts from the operating SHD to the SHD Topside Development. Nevertheless, depot replanning scheme has been carefully developed to minimize adverse noise impact to the SHD Topside Development. Details of consideration of depot replanning scheme are discussed in Section 2.3. It is feasible to provide canopy/noise barrier along the podium edge to protect future SHD Topside Development.

4.6.52 The following recommended mitigation measures as presented in Figure No. NEX1062/S/SHD/ACM/Z10/162 and NEX1062/S/SHD/ACM/Z10/164 are summarized below to mitigate the adverse noise impact from existing SHD operation:

· Noise canopy of 7m and 15m wide at the podium edge (at about 20mPD) to the north Blocks 143 to 149. The lengths of the noise canopy of 7m and 15m wide are approximately 150m and 30m respectively. This canopy will be maintained until commencement of Stage 3 SHD Replanning Works; and

· Cantilever noise barrier of 12m high (from 26.5 mPD to 38.5 mPD) and approximately 500m long with cantilever crown 4m x 4m extended at 45 degree to the north of Blocks 108 to 143. This noise barrier will be demolished when deemed necessary during Stage 3 SHD Replanning Works.

4.6.53 For Assessment Scenario 2 to 4, the noise exceedances are contributed by mainline (TCL and AEL) operation, which is dominant noise source in Siu Ho Wan. During the planning and preliminary design stage of the Project, the provision of noise enclosure on TCL/AEL tracks was reviewed.  Review findings indicate only limited clearance at the either side of TCL/AEL tracks with existing depot facilities to the north, NLH and Tuen Mun Chek Lap Kok Link Road on the south.  Such site constraints greatly reduce the constructability of noise enclosure on TCL/AEL tracks due to potential disturbance to existing SHD operation and also road traffic network of which temporary road closure required for supporting the construction.  In addition, due to proximity of running tracks, the stringent railway protection measures for running tracks restricts the allowable working hour for the enclosure construction to less than  2 hours each night, leading to prolonged construction period of the noise enclosure which may affect other maintenance activities.  High speed rail with speed about 130kph would also introduce high suction force on objects in the vicinity, together with the prolonged construction period, construction of noise enclosure on TCL/AEL tracks create undesirable high risk affecting the normal service of TCL/AEL.  It is therefore concluded that based on current design and operational information, the provision of noise enclosure on TCL/AEL tracks is not a practical and feasible mitigation proposal. In view of these, alternative noise mitigation measures with efficient and practicable construction method have been explored to be provided at the above ground structures of SHD Topside Development for protecting the future residents.

4.6.54 After exploring practical noise mitigation measures, noise canopies of 15m wide along the southern podium edge (at +23 mPD) has been found to be feasible in alleviating noise exceedance predicted at NSRs (Section 4.6.5 refers). A total of 7 sections of 15m wide noise canopy as shown in Figure No. NEX1062/S/SHD/ACM/Z10/163 will be provided. The typical sections of 15m wide noise canopy are shown in Figure Nos. NEX1062/S/SHD/ACM/Z10/165 and NEX1062/S/SHD/ACM/Z10/166. The safety and technical constraints in extending the noise canopy have been discussed in Section 4.6.5.

4.6.55 Noise mitigation measures may be revised depending on the evaluation during subsequent detailed design, the future developers may wish to explore any alternative approaches to achieve equivalent or even better environmental performance. During the detailed design stage, an environmental review may be conducted to study and optimise the extent of canopy and noise barrier that could help to reduce the rail noise impacts to allow scope in enhancing current development scheme of SHD Topside Development as assessed in this EIA. The future developers would need to demonstrate that the noise criteria can still be achieved by adopting their packages of mitigation measures.

4.6.56 There might be potential wheel squeal when train moving through sharp bends. The passenger trains has been installed with stick lubricator to minimize the potential wheel squeal, where necessary, further administrative measures including train wheel and rail lubrication techniques will be adopted, during the operation of existing SHD to minimize the potential wheel squeal.

4.6.57 The noise mitigation measures mentioned in Section 4.6.52 and Section 4.6.54 will be implemented by the developer of SHD Topside Development before population intake of relevant phase (Appendix 2.6 refers).

Mitigated Operational Noise Impact

4.6.58 With incorporation of the proposed rail noise mitigation measures, the mitigated railway noise levels are predicted with details of results presented in Appendix 4.19. The maximum mitigated railway noise levels are shown in Tables 4.31 to 4.36. Prediction results indicate that the rail noise levels at all representative NAPs comply with the noise criteria.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

Notes:

(1) The assessment only includes NSRs which rely on opened windows for ventilation.

(2) NAP – Noise Assessment Point

(3) Daytime and evening time criterion / night-time noise criterion is proposed according to TM-IND. Bold value denotes exceedance of noise criterion.

(4) N/A – Not Applicable. In accordance with Annex 13 of the TM-EIAO, country parks are considered to be a NSR. However, the TM-EIAO and TM-IND do not provide a specific noise limits for Country Parks. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse rail noise impact is anticipated.

(5) The predicted noise level less than 40 dB(A) is considered negligible.

(6) Rail noise from AEL/TCL including realigned section has been included in the assessment.

4.6.59 With the implementation of the recommended noise mitigation measures, the predicted railway associated with the operation of SHD, in terms of L_{eq, 30mins} and L_max, at all NSRs would comply with the noise criteria. Provided that the transient nature of visitor using hiking trails in the Country Park, no adverse railway noise impact is anticipated.

Cumulative Operational Noise Impact

Assessment Scenario 1A to 1C

4.6.60 It is anticipated that there would be cumulative noise impact at the representative NSRs in Phase 1 Topside Development due to the fixed plant sources of the Project and SHD Topside Development, and rail noise. The maximum cumulative operational noise levels have been assessed and are summarized in Table 4.37. Cumulative operational noise impact is presented in Appendix 4.20.

4.6.61 Based on the prediction result for Assessment Scenario 1A to 1C, the cumulative operational noise levels at the representative NSRs in Phase 1 Topside Development would comply with the NCO noise criteria (i.e. ANL) due to fixed noise sources and railway operation from the proposed Project and concurrent project.

Assessment Scenario 2

4.6.62 In Assessment Scenario 2, the existing and temporary SHD facilities in Phase 3 SHD area will be relocated under the concrete slab, hence the overall operational noise impact would be improved comparing to Assessment Scenario 1. The maximum cumulative operational noise levels at the representative NSRs have been assessed and summarized in Table 4.38.

4.6.63 Based on the prediction result for Assessment Scenario 2, the cumulative operational noise levels at the representative NSRs would comply with the NCO noise criteria (i.e. ANL) due to fixed noise sources and railway operation from the Project and concurrent project.

Assessment Scenario 3 and 4

4.6.64 In Assessment Scenario 3 and 4, all SHD facilities will be relocated under the concrete slab, hence the operational noise impact would be further reduced when comparing to Assessment Scenario 2. The maximum cumulative operational noise levels at the representative NSRs have been assessed and are summarized in Table 4.39 and Table 4.40 respectively.

4.6.65 Based on the prediction result for Assessment Scenario 3 and 4, the cumulative operational noise levels at the selected representative NSRs would comply with the NCO noise criteria (i.e. ANL) due to fixed noise sources and railway operation from the Project and concurrent project.

Evaluation of Residual Environmental Impacts

Fixed Plant Noise

4.6.66 With the adoption of appropriate measures such as acoustic louvres or silencers, it is expected the maximum allowable SWLs of planned noise sources could be achieved and the predicted fixed plant noise levels at the NSRs would comply with stipulated noise criteria.

Rail Noise

4.6.67 With the implementation of the recommended noise mitigation measures, the predicted railway associated with the operation of SHD, in terms of L_{eq, 30mins} and L_max, at all NSRs would comply with the noise criteria.

Cumulative Operational Noise Impact

4.6.68 The cumulative operational noise impact due to railway noise associated with the operation of SHD, railway noise from AEL/TCL operation and fixed noise sources from the Project and the concurrent project has been evaluated. Based on the assessment result, the cumulative operation noise levels at the selected representative NSRs would comply with the noise criteria of ANL as set in TM-IND.

4.7 EM&A Requirements

Construction Noise

4.7.1 The recommended mitigation measures should be implemented during construction stage. Details of the monitoring and auditing programme are provided in a stand-alone EM&A Manual.

Fixed Plant Noise

4.7.2 The assessment has indicated that the noise from the proposed fixed plant noise sources would comply with the noise criteria if the noise emissions from the proposed fixed plants are properly designed to meet the recommended maximum allowable SWL. No specific monitoring for the fixed plant operation is deemed necessary. Verification of the noise performance of the proposed fixed plants would be recommended during the testing and commissioning stage.

Railway Noise

4.7.3 Compliance check on railway noise against NCO criteria should be conducted before the population intake of relevant phase(s) of the SHD Topside Development that would be affected by the railway noise due to the operation of existing SHD. Details of the EM&A programme are provided in a stand-alone EM&A Manual.

4.8 Conclusion

Construction Noise

4.8.1 Construction noise impact arising from the use of PME for different construction activities has been assessed. With the implementation of practical mitigation measures including good site management practices, use of movable noise barrier, noise barrier, full enclosure and use of quiet plant, no unacceptable impact arising from the construction of the Project is anticipated.

Fixed Plant Noise

4.8.2 The noise impact associated with the operation of the fixed plant noise sources has been assessed.  The predicted fixed plant noise levels from the planned and existing fixed plant at the representative NSRs would be expected to comply with the day-time and night time criteria. With the proper selection of plant and adoption of acoustic treatment, the NSRs will not be affected by the noise from the planned ventilation louvres. No adverse impact arising from fixed plant noise sources due to the operation of the Project is expected.

Railway Noise

4.8.3 Based on assessment findings, noise exceedance would occur at various NSRs without provision of mitigation measures. With the implementation of the recommended noise mitigation measures, the predicted noise levels, in terms of L_{eq, 30mins} and L_max, at all representative NSRs would comply with the noise criteria, hence no unacceptable railway noise impact is anticipated.

Cumulative Operational Noise Impact

4.8.4 Based on the findings of cumulative operational noise impact assessment, the mitigated noise levels at all representative NSRs would comply with the noise criteria as stipulated in the TM-IND. It is therefore concluded that, with implementation of the recommended noise mitigation measures for fixed plant, mainline operation and train operation within SHD, there would be no adverse cumulative operational noise impacts to the NSRs.
