Noise Monitoring

      vi.            Noise monitoring during day time and evening time were conducted at the City Garden, Victoria Centre and Harbour Road Sports Center on a weekly basis in the reporting month. Four limit level exceedances were recorded at Harbour Road Sports Centre on 5, 16, 19 and 26 October 2010 during the evening time period. Investigation found that exceedances were not related to the Project.

 

Real-time Noise Monitoring

     vii.            Real-time noise monitoring at FEHD Hong Kong Transport Section Whitefield Depot and Oil Street Community Centre have been commenced on 5 October 2010 for the filling works of Contract no. HY/2009/11. Discontinuous limit level exceedances were recorded at these two stations during the restricted hour. Investigation found that exceedances were not related to the Project. Noise monitoring during day time and evening time were conducted at the City Garden on a weekly basis in the reporting period. Two limit level exceedances were recorded at M4a on 20 and 27 July 2010 during restricted hours. Investigation found that is not project related exceedances. Reviewed the past monitoring results and observation at Station M4a, Victoria Centre (Station ID: M4b) is proposed as alternative noise monitoring station from August 2010.

 

Noise monitoring during daytime was conducted at the M1a Harbour Road Sports Centre in this reporting month. Due to the marine works undertaken in evening time from 12 July 2010, noise monitoring during evening time was conducted from 13 July 2010. Three limit level exceedances were recorded at 3, 10 and 17 during restricted hourin reporting month. It is concluded as not related to the Project works. However, baseline noise level at M1 needs to be reviewed in next reporting month.Investigation found that is not project related exceedances.

 

Air Quality Monitoring

   viii.            Air quality monitoring has been conducted at stations CMA1a – Oil Street Community Liaison Centre and CMA2a – Causeway Bay Community Centre. As no filling works for Contract no. HY/2009/11 was carriedcommenced  out in mid-reporting monthAugust 2010, no air quality monitoring at stations CMA1b Oil Street Community Liaison Centre and CMA2a – Causeway Bay Community Centre was were undertakencommenced during on 11 August 2010the reporting month. One No action level exceedance of 1hour TSP was recorded at CMA1b on 24 August 2010. Investigation found that exceedance was not related to the Project.in the reporting month.

 

Water Quality Monitoring

     i.            Water quality monitoring at 17 monitoring stations werewas conducted three days per week during the reporting period.  The action and limit level exceedances of water quality monitoring are summarized in Table I. Investigations were found that the exceedances are not related to the Project works. The details of the exceedances can be referred to Section 5.3 and 6.3 of the report.

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.        In the reporting month, the dredging works for Contracts no. HK/2009/01 and HK/2009/02 were commenced on 23 July and 5 July 2010 respectively.  The details of individual contracts are summarized in Table 2.2.
