1.1 Project Background
1.1.1.1 The 30-hectare Siu Ho Wan Depot (SHD) has been highlighted in both 2015 and 2016 Policy Address as a potential railway site being explored by MTR Corporation Limited (MTRCL) (the Project Proponent) in collaboration with the Government to provide housing supply.
1.1.1.2 In the 2017 Policy Address, the Chief Executive announced the initiative to commence the statutory planning procedures for SHD this year, with the aim to provide not less than 14,000 residential units in the medium to long term.
1.1.1.3 The Lantau Development Advisory Committee (LanDAC) has also recommended “Strategic Economic and Housing Development” as the planning theme for the North Lantau Corridor. The proposed comprehensive development atop SHD is in line with the planning theme, which has been earmarked as one of the medium-term projects in the First-term Work Report published by LanDAC in January 2016.
1.1.1.4 The Project Proponent supports Government’s policy initiative to make better use of railway land to provide housing supply by commissioning a consultancy study to optimise the development potential of SHD and formulate a development scheme for a Comprehensive Residential and Commercial Development (the Project) which forms the basis of this Environmental Impact Assessment (EIA) Report. A new Siu Ho Wan Station (SHO) has been proposed along the Tung Chung Line (TCL) to meet the transportation needs of the development and enable building of a sustainable community.

1.3 The Project
1.3.1.1 Key elements as described in EIA Study Brief (ESB-294/2016), the proposed development includes the following:
· Topside development including podium, development of residential towers with building height of about +86mPD to about +106mPD to provide about 14,000 flats, along with commercial / retail facilities, schools and kindergartens, car parking and loading / unloading facilities, public transport interchange (PTI), utility plants rooms and other supporting facilities.
· Upgrading of the sewerage network including installation of new sewage pumping stations and construction of rising mains to cater for sewage generated by the Project;
· A new Siu Ho Wan Station (SHO) and the associated track works;
· Railway depot replanning works within the existing site boundary; and
· Construction of concrete slab within the existing depot for podium decking and property enabling works for the topside development.
1.3.1.2 After the issue of EIA Study Brief (ESB-294/2016), more design details on depot replanning and SHO construction were developed. It was proposed to prepare two EIA studies to cover respectively the topside development related works (SHD Topside Development EIA) under ESB-294/2016 and railway related works (Railway EIA) under ESB-296/2016. The arrangement of two separate EIA studies respectively for topside development and railway related works is to streamline for project implementation and for the ease of reference of the public.
1.3.1.3 According to the latest arrangement, key elements to be implemented under this Project only include the topside development and the upgrading of the sewerage networks with installation of new sewage pumping station and construction of rising mains. Other key elements including the railway depot replanning, construction of concrete slab above the depot, and the new SHO and the associated track works will be addressed in another EIA report for Siu Ho Wan Station and Siu Ho Wan Depot Replanning Works (Railway EIA), which would be submitted separately for approval under the Environmental Impact Assessment Process of the EIAO.
1.3.1.4 This SHD Topside Development EIA and the Railway EIA have been conducted concurrently. Potential environmental interface issues have been addressed in detail collaboratively in the course of the two EIA studies, and findings presented to address the corresponding requirements of the two EIA study briefs (ESB-296/2016 and ESB-294/2016). The two studies have also assessed cumulative impacts of all project elements covered in these two study briefs.
1.3.1.5 The Project would also include the eastern connection access on Sham Shui Kok Drive and the western access via Tai Ho Interchange. The eastern connection access on Sham Shui Kok Drive is an at-grade road of about 1000m while the western access via Tai Ho Interchange is a short viaduct of approximately 50m long. The environmental impacts of the eastern connection access and the western access during construction and operational stages would be included in this EIA study. For western access, which would be the access to both Siu Ho Wan Station and Siu Ho Wan Depot Replanning Works (SHO and SHD Replanning Works) and the Project, may be constructed under the Project or the SHO and SHD Replanning Works which would be further delineated in the detailed design stage, both Railway EIA and SHD Topside Development EIA assessed relevant impact associated with the construction and operation of the western access as conservative case scenario.
1.3.1.6 The location plan for the proposed development and associated infrastructure works to be implemented is shown in Figure 1.1. More detailed description of the proposed comprehensive residential and commercial development atop Siu Ho Wan Depot is given in Section 2.
1.3.1.7 Despite the implementation strategy that only some of the elements in EIA Study Brief (ESB-294/2016) will be implemented under this project, the impacts caused by other elements that are described in EIA Study Brief (ESB-296/2016) but covered in the Railway EIA would also be described in this EIA to satisfy the statutory requirements in EIA Study Brief (ESB-294/2016). The cumulative impacts of all elements in EIA Study Brief (ESB-294/2016) will also be discussed in this EIA.
SHO and SHD Replanning Works
1.3.1.8 The SHO will be implemented to meet the future demand of topside development. The construction of SHO and the associated modification of railway tracks will commence in 2019 and are targeted for completion by 2026. The overall environmental impacts including fugitive dust, airborne noise, water quality, ecology, fisheries, sewage and sewerage implications, waste, land contamination, landscape and visual and hazard to life during construction phase of the Project and they have been addressed in this EIA report. In addition, overall impacts on air quality, fixed noise, rail noise, water quality, ecology, fisheries, sewage and sewerage implications, waste, land contamination, hazard to life, and landscape and visual during operational phase are also addressed in this EIA report.
1.3.1.9 Similarly, SHD replanning works will be implemented to enable the construction of the proposed development. The construction of SHD replanning works will commence in 2019 and are targeted for completion by 2036. Hence, overall environmental impacts including fugitive dust, airborne noise, water quality, ecology, fisheries, sewage and sewerage implications, waste, land contaminations, hazard to life, and landscape and visual during construction phase of the Project will be addressed in this EIA report. Since the construction of SHD replanning works will be implemented in stages, environmental impact during interim stages will also be addressed. In addition, overall impacts on air quality, fixed noise, rail noise , water quality, ecology, fisheries, waste, land contamination, sewage and sewerage implications, hazard to life, and landscape and visual during operational phase are addressed in this EIA report.
1.4.1.1 In accordance with the requirements of Section 5(1) of the EIAO, a Project Profile (No. PP-542/2016) for the Project was submitted to the Director of Environmental Protection (DEP) for application for an EIA Study Brief on 20 July 2016. Pursuant to Section 5(7)(a) of the EIAO, the DEP issued a Study Brief (No.: ESB-294/2016 dated 1 September 2016) for the EIA study.
1.4.1.2 The purpose of this EIA study is to provide information on the nature and extent of environmental impacts arising from the construction and operation of the Project and related activities that take place concurrently. This information will contribute to decisions by the Director on:
· The acceptability of any adverse environmental consequences that are likely to arise as a result of the Project;
· The conditions and requirements for the detailed design, construction and operation of the Project to mitigate against adverse environmental consequences wherever practicable; and
· The acceptability of residual impacts after the proposed mitigation measures are implemented.
1.5.1.1 The Comprehensive Residential and Commercial Development atop Siu Ho Wan Depot is a DP under Item 1 Schedule 3 of EIAO – Engineering feasibility study of urban development projects within a study area covering more than 20ha or involving a total of population of more than 100,000.
1.5.1.2 It also comprises the following which are classified as a Designated Project (DP) as per Schedule 2, Part I of the EIAO.
· Item F.3(b) – A sewage pumping station with an installed capacity of more than 2000m3 per day and a boundary of which is less than 150m from an existing or planned residential area or educational institution (i.e. ultimate sewage pumping station);
· Item A.2 – Railway Station (i.e SHO and associated trackworks on AEL/TCL); and
· Item A.4 – A railway siding, depot, maintenance workshop, marshalling yard or goods yard (i.e. operation of SHD).
1.5.1.3 As discussed in Section 1.3, Schedule 2 DPs Item A.2 and Item A.4 are railway related DPs which will be separately covered in the Railway EIA to be submitted for approval under the EIAO in order to streamline for project implementation and for the ease of reference of the public. Nonetheless, Schedule 2 DPs Item A.2 and Item A.4 are discussed in this EIA to fulfil the statutory requirements of ESB-294/2016.
Non-Designated Projects in this Project
1.5.1.4 Apart from the Schedule 2 Designated Projects (DP) elements (Details refer to Section 1.5), there are a number of Non-Schedule 2 DP elements as discussed in Sections 1.3.1.1 to 1.3.1.5. However, should there be any change to the non-Schedule 2 DP element of the proposed development (including but not limited to development scheme, parameter and implementation programme) after the approval of this EIA report, supplementary environmental assessments should be carried out as required by relevant authorities to satisfy the latest planning mechanism and other statutory requirements at that time without the need for a new EIA.

· HZMB Hong Kong Link Road (HKLR); and,
1.7.1.2 Detailed justifications on consideration of various environmental cumulative impacts from individual concurrent projects has been included in corresponding technical sections.
Tung Chung New Town Extension (TCNTE)
1.7.1.3 The project comprises approximately 130ha of reclaimed land and 120ha existing land for the development of Tung Chung East and Tung Chung West developments respectively. Besides the residential and commercial development, different infrastructural works would also be carried out. The Road P1 (Tung Chung - Tai Ho Section) would also be built under the Tung Chung New Town Extension project. The construction phase of the project would commence in 2017 and would be completed by 2030.
1.7.1.4 There is a large separation distance of about 1.2km between the Tung Chung New Town Extension (Tung Chung East Planning Area) and the proposed development. However, the Road P1 (Tung Chung – Tai Ho Section) is only 50m away from the western boundary of the proposed development. Cumulative environmental impacts (including airborne noise and water quality) during construction phase of the Project is therefore anticipated. The vehicular emissions and road traffic noise generated would have certain cumulative impacts on the Project. Cumulative visual impacts may be generated due to visual character changes by the appearance and building structures of TCNTE development.
Additional sewage rising main and rehabilitation of the existing sewage rising main between Tung Chung and Siu Ho Wan
1.7.1.5 The scope of this concurrent project comprises construction of an additional sewage rising main of about 6.5km with diameter 1,200mm from Tung Chung sewage pumping station to Siu Ho Wan sewage treatment works and rehabilitation of the existing sewage rising main with diameter of 1,200mm.
1.7.1.6 This concurrent project has no major site formation and thereby it is anticipated that there is no cumulative impact on fugitive dust. However, use of powered mechanical equipments (PMEs) would lead to cumulative impacts on airborne noise.
Hong Kong – Zhuhai – Macao Bridge (HZMB) Hong Kong Boundary Crossing Facilities (HKBCF)
1.7.1.7 The proposed HZMB HKBCF is built on an artificial island that reclaimed from open waters off northeast of HKIA. The HZMB HKBCF comprises cargo and passenger clearing and vehicle inspection facilities, government offices, public transport interchange and the like. It is connected by the Hong Kong-Zhuhai-Macao Bridge Link Road (HZMB HKLR), TM-CLK Link, and other roads to HKIA.
1.7.1.8 The construction of HZMB HKBCF commenced in 2011, and is targeted to achieve readiness by the end of 2017. However, given the large separation distance of about 2km from HZMB HKBCF, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project.
Topside Development of HKBCF
1.7.1.9 Besides the essential cargo and passenger clearing and vehicle inspection facilities and government offices on HZMB HKBCF, a planning, engineering and architectural study is now being conducted to explore the feasibility of developing large-scale hotel, dinning, shopping and entertainment facilities to develop bridgehead economy and optimize the HKBCF. There is currently no programme for the construction of the topside development of HKBCF.
1.7.1.10 Given the large separation distance of about 2km between HZMB HKBCF and the proposed development, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project.
Hong Kong International Airport (HKIA) Three-Runway System (3RS)
1.7.1.11 The 3RS would be located on a new reclaimed land of approximately 650ha to the north of the HKIA. The project would involve a new third runway with associated taxiways, aprons and aircraft stands, new passenger concourse building, expansion of the existing Terminal 2 Building and related works and facilities.
1.7.1.12 Given the large separation distance of about 5km between 3RS and the proposed development, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project.
North Commercial District (NCD) at the Hong Kong International Airport (HKIA)
1.7.1.13 The area of NCD is currently occupied by the Asia-World Car Park and the Skycity Nine Eagles Gold Course. Different commercial developments and business activities, such as hotel, office, retail and recreational facilities would be developed within the NCD. The planning studies of the NCD is now being conducted by the Airport Authority Hong Kong and first phase of NCD is targeted for completion in 2021.
1.7.1.14 Given the large separation distance of about 4.2 km between the NCD and the proposed development, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project.
Organic Waste Treatment Facilities – Phase 1 (OWTF-Phase 1)
1.7.1.15 OWTF-Phase 1 is a biological treatment facility with a capacity of about 200 tonnes per day for converting organic waste into reusable compost and biogas. The facility comprises pre-treatment facilities, an anaerobic digestion process, post-treatment facilities, energy recovery system and air and wastewater treatment facilities. It is anticipated that the OWTF-Phase 1 would be commissioned in 2017.
1.7.1.16 Due to the large separation of about 770m between OWTF-Phase 1 and the proposed development and the construction of OWTF-Phase 1 would be completed before the commencement of construction phase of the proposed Project, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project. Besides, odour emission from OWTF is also anticipated during operational phase.
Tuen Mun – Chek Lap Kok Link (TM-CLK Link)
1.7.1.17 TM-CLK Link includes a 9-km long dual two-lane carriageway between Tuen Mun and North Lantau. This strategic road link is designed to meet the anticipated road traffic demand generated by HZMB and to provide significant reduction in travelling distance and time across, northwest New Territories, HKIA and North Lantau.
1.7.1.18 The TM-CLK Link Southern Connection is anticipated to be completed in the 1st half of 2019 at the earliest whilst the Northern Connection is anticipated to be completed by 2020 at the earliest. Therefore there would be no cumulative impacts during construction phase. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project and would be addressed in this EIA study.
Hong Kong-Zhuhai-Macao Bridge (HZMB) Hong Kong Link Road (HKLR)
1.7.1.19 The HZMB HKLR is a 12km-long road connecting the HZMB HKBCF to the HZMB Main Bridge. The HZMB HKLR comprised of a 9.4km long viaduct from Hong Kong boundary to Scenic Hill on the airport island, a 1km long tunnel section to the land formation formed along the east coast of the airport island and a 1.6km long at-grade road section on the land formation connecting to HZMB HKBCF. The construction of HZMB HKLR commenced in 2012 and is target to achieve readiness for commissioning by end 2017.
1.7.1.20 Given the large separation distance of about 3.8km between HZMB HKLR and the proposed development, cumulative environmental impacts during construction phase of the Project is not anticipated. However, the vehicular emissions and road traffic noise would have certain cumulative impacts on the Project.

Notes:
[1] The concurrent projects are located outside of the 500m assessment area of the proposed development.
[2] Traffic noise and vehicular emission caused by induced traffic.
[3] The construction phase of the concurrent projects would be completed before the commencement of construction phase of the proposed Project. Thus, cumulative environmental impacts are not anticipated.
[4] As advised by CEDD, Siu Ho Wan (SHW) Reclamation and Road P1 (SHW Section) are in feasibility stage and has no implementation programme, thus not considered as concurrent project. These future projects, if proceed, will observe requirements in EIAO and take the SHD development as a committed project for the purpose of assessing cumulative impacts as appropriate.
[5] Development at Siu Ho Wan and Associated Transport Infrastructures, Sediment Disposal Facility in South of Brothers, and the remaining identified Potential Near Shore Reclamation Sites in Western Waters of Hong Kong under Increasing Land Supply by Reclamation and Rock Cavern Development cum Public Engagement (i.e. Sunny Bay and Lung Kwu Tan) are also some concurrent projects in the North Lantau Waters but they would not contribute to any potential cumulative environmental impacts as the Project does not consist of any marine based development. These projects have been further discussed in Section 9.
[6] This concurrent project is still under planning stage and the programme has yet to be confirmed.
[7] First phase of NCD is targeted for completion in 2021.
