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:

¡P 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

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

¡P 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

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

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

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

¡P 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.

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 the dredging and filling works at North Point Reclamation Shoreline Subzone (NPR2E) and (NPR1& NPR2W), the filling at WCR1 and dredging at Wan Chai Reclamation Shoreline Subzone (Submarine sewage pipeline) respectively, filling at HKCEC1 and dredging at TCBR and filling at TPCEAE, and the dredging works at MTR Tunnel Crossing in the reporting month. The major environmental impact was water quality impact at North Point and Wan Chai.

7.0.4. The major environmental impacts generated from the filling work at Central Reclamation Phase III were only located along the coastline of Central and Admiralty. The exceedances at C3 are potentially due to localized sources (the filling operation at HKCEC water channel) and were unlikely due to cumulative impact from CRIII. It is evaluated the cumulative construction impact from the concurrent projects including Wan Chai Development Phase II and Central Reclamation Phase III was insignificant.

8.0.7. An incident on dispersed muddy boom was observed by the IEC on 1 April 2011 in the area between outside the government helipad and eastern temporary seawall at WCR1. Silt curtain at the breakwater of TPCWA was maintained while the silt curtain for the reclamation shoreline subzone at TPCWAE was opened at the time of observation and some localized muddy boom at TPCWA was observed. Further investigation by ET revealed that:

¡P Muddy discharge from unknown source generated from the existing Box Culvert N was considered to be the major cause, possibly due to local discharge from unknown source at the stormdrain upstream to Box Culvert N. Muddy boom was further dispersed by current movement outside the government helipad.

¡P Localized mud plume emerged within the ex-Cargo area was not properly enclosed by silt curtain producing some minor impact around the breakwater at TPCWA.

¡P Defects found for the silt curtains deployed in TPCWAE reduced the effectiveness of the silt curtain system.

8.0.8. Contractor of HY/2009/15 was urged to rectify the defects found for the silt curtains. Further independent diver inspection on the silt curtain on 14 Apr 2011 confirmed the silt curtain was in proper condition. Silt curtain deployment plan was subsequently revised to include specific details on the marine access for TPCWAE. No further dispersion was observed after a week's operation and this case was closed.

8.0.9. Frequent muddy boom dispersion were observed around the marine entrance to the TPCWA on 2, 5 & 6 April 2011, resulting in escape of muddy boom through the marine access of the ex-Cargo Area. Further investigation by ET revealed that escape of silt from the filling area at TPCWA eventually lead to frequent dispersion of muddy boom by routine towing action. Filling operation was immediately suspended by contractor of HY/2009/15 for review of silt curtain and towing operation. Site trial towing was conducted on 14 Apr 2011 and found that a reduced towing speed of 0.5 nautical miles per hour could control the dispersion of muddy boom within the area enclosed by silt curtain. No further dispersion was observed after a week's operation and this case was closed.

9. Complaints, Notification of Summons and Prosecution

9.0.1. There were two environmental complaints received in this reporting month.

9.0.2. A dust impact and mosquitoes breeding complaint from Government Complaint Hotline ICC direct referral (ICC#1- 281451236) was received by ET on 18 April 2011. The complaint was reported by the resident, Mr Law at Victoria Centre that dust generated at 10:04 on 15 April in which suspected the filling operation was part of North Point Reclamation.

9.0.3. The concerned stockpile was a working stockpile and was covered at night time after work. Water spraying on the haul road and potential dust generating material at least 4 times a day was conducted by contractor that complies with the requirement. It is considered invalid but preventive actions can be taken because the stockpile is relatively large and easily visible by complainant. The concern of mosquitoes breeding is not under the scope of EM&A, the follow-up action are not reported in this monthly EM&A report.

9.0.4. Another complaint was reported from a resident, Ms Chiu at Victoria Centre via the Government Complaint Hotline ICC direct referral (ICC# 1-272874759) regarding the episode of night noise on 19/4/11 and 20/4/11 at 2:50 am and the noise lasted for 30 minutes per night. According to the RSS¡¦s record, there was no construction works undertaken under the EP-356/2009 during the concern time period. Besides, there was no abnormal real-time noise monitoring data recorded in RTN1 - FEHD Hong Kong Transport Section Whitefield Depot which is next to the Victoria Centre. As such, it is considered as invalid complaint under this Project.
