2      Project Background

2.1          Background

2.1.1.     “Wan Chai Development phase II and Central-Wan Chai Bypass” and “Central-Wan Chai Bypass and Island Eastern Corridor Link” (hereafter called “the Project”) are Designed Project (DP) under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). The Environmental Impact Assessment (EIA) Reports for Central-Wan Chai Bypass and Island Eastern Corridor Link (Register No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and 11 December 2008 respectively.

2.1.2.     The key purpose of Wan Chai Development Phase II (WDII) is to provide land at Wan Chai North and North Point for construction of the Central-Wan Chai Bypass and Island Eastern Corridor Link (CWB). Land formed under the project will be developed as a world-class waterfront promenade joining that at the new Central waterfront for public enjoyment.

2.1.3.     There is a compelling and present need for the CWB to provide relief to the very congested east-west Connaught Road Central/Harcourt Road / Gloucester Road Corridor (the Corridor) which is currently operating beyond its capacity. The CWB will provide relief to the existing congestion along the Corridor and cater for the anticipated growth of traffic on Hong Kong Island. Without the CWB and its access roads, there will not be sufficient capacity to serve the heavy traffic demands at both strategic and local levels.

 

2.2          Scope of the Project and Site Description

2.2.1.     The Project is located mainly in Wan Chai North, Causeway Bay and North Point, and is demarcated by Gloucester Road and Victoria Park Road to the south, Fenwick Pier Street to the west and Tong Shui Road Interchange to the east, as shown in Figure 2.1.

2.2.2.     The study area encompasses existing developments along the Wan Chai, Causeway Bay and North Point shorelines. Major land uses include the Hong Kong Convention & Exhibition Centre (HKCEC) Extension, the Wan Chai Ferry Pier, the ex-Wan Chai Public Cargo Working Area (ex-PCWA), the Royal Hong Kong Yacht Club (RHKYC), the Police Officers’ Club, the Causeway Bay Typhoon Shelter (CBTS) and commercial and residential developments.

2.2.3.     The scope of the Project comprises:

·          Land formation for key transport infrastructure and facilities, including the Trunk Road (i.e. CWB) and the associated slip roads for connection to the Trunk Road and for through traffic from Central to Wan Chai and Causeway Bay. The land formed for the above transport infrastructure will provide opportunities for the development of an attractive waterfront promenade for the enjoyment of the public

·          Reprovisioning / protection of the existing facilities and structures affected by the land formation works mentioned above

·          Extension, modification, reprovisioning or protection of existing storm water drainage outfalls, sewerage outfalls and watermains affected by the revised land use and land formation works mentioned above

·          Upgrading of hinterland storm water drainage system and sewerage system, which would be rendered insufficient by the land formation works mentioned above

·          Provision of the ground level roads, flyovers, footbridges, necessary transport facilities and the associated utility services

·          Construction of the new waterfront promenade, landscape works and the associated utility services

·          The Trunk Road (i.e. CWB) within the study area and the associated slip roads for connection to the Trunk Road.

 

2.2.4.     The project also contains various Schedule 2 DPs that, under the EIAO, require Environmental Permits (Eps) to be granted by the DEP before they may be either constructed or operated. Table 2.1 summarises the five individual DPs under this Project. Figure 2.1 shows the locations of these Schedule 2 DPs.

2.3          Division of the Project Responsibility

2.3.1.     Due to the multi-contract nature of the Project, there are a number of contracts sub-dividing the whole works area into different work areas to be commenced. Contractors of individual contracts will be required by the EP holder to apply Further Environmental Permits (FEP) such that the impact monitoring stations are sub-divided accordingly to facilitate the implementation of EM&A programme and to streamline the EM&A reporting for individual FEP holders correspondingly.

2.3.2.     The details of individual contracts are summarized in Table 2.2.

6.4.2       After checking with contractor, no marine activity was conducted at Causeway Bay Typhoon Shelter on 2 July 2016 and 25 July 2016. In view of no marine construction activity, and no exceedance recorded on the subsequent monitoring, it was considered that the exceedances were not project related.

6.4.3       There were 2 limit level DO exceedances recorded at Ex-WPCWA SW on 2 July 2016 and 4 July 2016 in this reporting month.

6.4.4       After checking with contractor, transfer of mud from shaft B to barge was observed conducted at Ex-PCWA during sampling on 2 July 2016 and silt curtain was observed deployed at the outfall location of culvert O. The silt curtain was observed partially deployed (without extending to water column) at the outfall location of culvert O. In view of the environmental concern on potential accumulation of organic pollutant in relate to the embayment effect at the concerned location due to the silt curtain deployment, the contractor was advised to remove any silt curtain/ impermeable deployed at the outfall location of culvert O. All obstruction at the outfall location of culvert O was subsequently removed by contractor on 5 July 2016. No further dissolved oxygen exceedance was recorded during subsequent monitoring conducted on 4 July 2016. Considering the upstream organic discharge influence and the partial silt curtain deployment (without extending to water column) observed during monitoring, the implication of the partially deployed silt curtain on the water circulation could not concluded. Nevertheless, the contractor was advised that any silt curtain/ impermeable barrier shall not be deployed at the culvert O outfall location so that the water circulation would not be adversely affected. In addition, the contractor was reminded to maintain a tarpaulin sheet between the shaft and barge during soil material transfer to avoid potential drop off to nearby waters and to maintain a proper deployment of silt curtain extending throughout the water column around the derrick barge during excavated material transfer to avoid potential muddy dispersion.

6.4.5       Removal of steel brackets was observed conducted at Ex-PCWA during sampling on 4 July 2016 and impermeable barrier was observed deployed at the outfall location of culvert O.

In view of the environmental concern on potential accumulation of organic pollutant in relate to the embayment effect at the concerned location due to the silt curtain deployment, the contractor was advised to remove any silt curtain/ impermeable deployed at the outfall location of culvert O. All obstruction at the outfall location of culvert O was subsequently removed by contractor on 05 July 2016. No further dissolved oxygen exceedance was recorded during subsequent monitoring conducted on 04 July 2016. Considering the upstream organic discharge influence and the partial impermeable barrier deployment (without extending to water column) observed during monitoring, the implication of the partially deployed impermeable barrier on the water circulation could not concluded. Nevertheless, the contractor was advised that any silt curtain/ impermeable barrier shall not be deployed at the culvert O outfall location so that the water circulation would not be adversely affected.

6.4.6       There were 1 action level DO exceedances recorded at Ex-WPCWA SE on 22 July 2016 in this reporting month.

7.         Cumulative Construction Impact due to the Concurrent Projects

7.0.1.     According to Condition 3.4 of the EP-356/2009, this section addresses the relevant cumulative construction impact due to the concurrent activities of the current projects including the Central Reclamation Phase III, Central-Wanchai Bypass and Island Eastern Corridor Link projects.

7.0.2.     According to the Final EM&A Report of Central Reclamation Phase III (CRIII) for Contract HK 12/02, the major construction activities were completed by end of January 2014 and no construction activities were undertaken thereafter and the water quality monitoring was completed in October 2011 and no Project-related exceedance was recorded for air and noise monitoring.  It can be concluded that cumulative construction impact due to the concurrent activities of the current projects with the Central Reclamation Phase III (CRIII) was insignificant.

7.0.3.     According to the construction programme of Central-Wanchai Bypass at Wanchai West at the Central Reclamation Phase III area include structural works for tunnel construction, road works and drainage works, and seawall modification were performed in July 2016 reporting month. As no project related exceedance were recorded during the reporting period, cumulative construction impact due to the concurrent activities of the current projects with the Central Reclamation Phase III (CRIII) was considered as insignificant. 

7.0.4.     According to the construction programme of Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, the major construction activities under Wan Chai Development Phase II were tunnel works at Wan Chai East and culvert construction, tunnel construction and ELS works at Wan Chai West. The major construction activities under Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were road works and ventilation building construction at Central Interchange, temporary reclamation removal works at Ex-PCWAW, ELS works and retaining wall construction at Victoria Park, ELS works and tunnel works at TS3; bridge construction, piling and tunnel works at North Point area in the reporting month. In addition, other non-Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects was observed undertaken at Wan Chai North and North Point area.

7.0.5.     No significant air impact from construction activities was anticipated in the reporting month. Besides, no project related exceedance was recorded during the air and noise environmental monitoring events in the reporting month. Thus, it is evaluated that the cumulative construction impact from the concurrent projects including Central Reclamation Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass (CWB), Island Eastern Corridor Link projects (IECL) was insignificant.
