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.

6.     Complaints, Notification of Summons and Prosecution

6.0.1.        There was one environmental complaint received on 26 August 2011.

6.0.2.        There was one environmental complaint received on 14 October 2011.

6.0.3.        Two environmental complaints were received on 4 and 6 November 2011.

Reporting month of September 2011

6.0.4.        A water impact complaint was received by ET on 29 August 2011. It was complained by Mr. Au from Cayley Property Management Limited (CPML) that large amount of rubbishes were found at the harbour front adjacent to their cooling water intake suction which caused 3 times of system breakdown of the sea water pump on 9, 22 and 25 August 2011 after the contractors set up the temporary garbage defender in function and collect the floating refuses, but cannot eliminate all refuses, in particular the refuse coming from the seabed. An ad-hoc inspection of the effectiveness of garbage defender was conducted with RSS (CWB project team), contractors of HY/200911 and HY/2009/19, ET and IEC on 29 August 2011.

6.0.5.        During on-site inspection, floating refuses were observed occasionally outside the garbage defender. No conclusion could be made for the source of these floating refuses. On the other hand, some of the refuses were observed floating behind the garbage defender during investigation. All daily cleaning actions had been taken by contractor to minimize floating refuse inside the construction site. It was noted that the cooling water intake was accessible to the public. As such, fish breeding and fishing activities were observed even though a notice has already hoisted. Also, tripping of rubbish by the passers-by could result in a lot of rubbish accumulated around the intake point.
