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.        Design and Construction of Central – Wan Chai Bypass and Island Eastern Corridor Link under the Project involves the construction and operation of a trunk road and its road tunnel more than 800m in length between portals that is shown at Figure 2.1.

2.2.2.         The study area encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:

·          A dual three-lane trunk road, approximately 4.5 km in length, and tunnel approximately 3.7 km in length defined from the connection with the existing Rumsey Street Flyover in Central, through to a connection with the existing Island Eastern Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);

·          The Central Interchange near the Rumsey Street Flyover to provide road connections to the Central area;

·          Tunnel control buildings and ventilation buildings;

·          Slip roads to connect the CWB to the local road system in the Wan Chai North and Causeway Bay area;

·          Associated road lighting, road signing, traffic control and surveillance system; and

·          Other associated works.

 

2.2.3.        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.

Noise Monitoring Parameters, Frequency and Duration

4.1.3.        The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30 minutes) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. For all other time periods, Leq (5 minutes) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.

4.1.4.        Noise monitoring shall be carried out at all the designated monitoring stations. The monitoring frequency shall depend on the scale of the construction activities. The following is an initial guide on the regular monitoring frequency for each station on a weekly basis when noise generating activities are underway:

·          One set of measurements between 0700 and 1900 hours on normal weekdays.

4.1.5.        Real time noise shall be carried out at the designated monitoring stations. The following is an initial guide on the regular monitoring frequency for each station on a 24 hours daily basis when noise generating activities are underway:

·          One set of measurements between 0700 and 1900 hours on normal weekdays.

·          One set of measurements between 1900 and 2300 hours on normal weekdays and 0700 and 2300 hours on public holidays.

·          One set of measurements between 2300 and 0700 hours on next day on everyday.

4.1.6.        If construction works are extended to include works during the hours of 1900 – 0700 as well as public holidays and Sundays, additional weekly impact monitoring shall be carried out during respective restricted hours periods. Applicable permits under NCO shall be obtained by the Contractor.

7.0.2.        From the Monthly EM&A report (May 2011) of Central Reclamation Phase III the key works in May 2011 are as follows:

·          Type A filling in FRAW and FRAE above +2.5mPD

·          General filling works above +2.5mPD in IRAE

·          Surcharging in FRAW and FRAE

·          Construction of cantilever slab at caisson

·          Construction of storm and foul drainage and gullies in hinterlands for Road P2, Road D7, and Road D9

·          Construction of GPO boundary wall

·          Construction of PLA boundary wall and entrance

·          Construction of Promenade enhancement works

·          Construction of buildings at PLA berth

·          Road P2 Underpass ramp structures

·          Precasting for retaining wall (offsite)

·          Installation of cooling mains discharge pipes in FRAE and FRAW

·          Bulk excavation to formation level at CWB works

·          Construction of CWB structure

·          Disposal of material off-site to Government fill banks

·          Strengthening of Man Yiu Street Footbridge

 

7.0.3.        According to the construction programme of Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, the major construction activity under Wan Chai Development Phase II was the filling works at North Point Reclamation Stage 1(NPR1), dredging works and filling works at Wan Chai Reclamation Stage 1(WCR1), Advanced piling works at FEHD Whitfield Depot, Central Interchange, cross-harbour water mains and marine pre-drilling in the reporting month. The major environmental impact was water quality impact at North Point and Wan Chai. Land-based construction activity was only advance piling works at FEHD Whitfield Depot, sheet piling and pre-drilling works at Central, pre drilling at North Point in the reporting month and tunnel works at Wan Chai East.

7.0.4.        The major environmental impacts generated from the Central Reclamation Phase III were located along the coastline of Central and Admiralty while advanced piling works at FEHD Whitfield Depot were undertaken and sheet piling, pre-drilling works at Central and tunnel works at Wan Chai East in the reporting month. No significant air, noise impact were anticipated in the reporting month. Besides, no environmental monitoring exceedance was recorded from the Project in the reporting month.  Thus, it is evaluated that the cumulative construction impact from the concurrent projects including Wan Chai Development Phase II and Central Reclamation Phase III was insignificant.
