  1. Turbidity and SS exceedances at C8 on 30 December 2010 were recorded.  Due to intake owner's constraint, delay was experienced in the re-provision of modified frame-type silt screen to protect City Garden intake against potential impact arising from the dredging works and accumulation of discharge and pollutants from nearby outfall adjacent to the intake. The exceedances were confirmed related to HY/2009/11 contractor difficulties in the provision of frame type silt screen.  Contractor enhanced mitigation measures with a double layer silt curtain on 7 Jan 2011. No further exceedance was recorded after installation of double layer silt curtain. Close monitoring on contractor mitigation and the variation of water quality results will be maintained. Contractor will further liaise with the owner on the re-provision of the frame-type silt screen.

 

Complaints, Notifications of Summons and Successful Prosecutions

  1. There were no environmental complaint was recorded in the reporting month.

 

  1. An incident of split hopper barge named Shun Tat 11 (Licence no. B21623V) for the Contract no. HK/2009/01 was recorded at the location near Cross Harbour Water Mains marine work zone on 24 January 2011.  The ballast tank on the port side of the split hopper barge was flooded with water. The split hopper barge was towed back to the dredging zone within a short period and immediately opened its hopper to dump the sediment back to the same dredging trench. It is suspected that the hull on the port side might be broken causing ingress of seawater into the ballast tanks. Meanwhile, the barge has been demobilized from the site and currently anchored at To Kwa Wan Typhoon Shelter. The emergency dumping was notified to EPD at 10:00a.m. on 24 January 2011. This barge will not be deployed to the site under HK/2009/01 to dispose the dredged sediment until it has been repaired and inspected by the competent surveyor. The incident will be kept in view for determining further follow up and remedial measures.

 

Site Inspections and Audit

  1. The Environmental Team (ET) conducted weekly site inspections for Contract nos. HY/2009/11, HK/2009/01, HK/2009/02 and HY/2009/15 under EP no. EP-356/2009 in the reporting month.

Section 10      Conclusion

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.

6.4               Water Quality Monitoring

 

Contract no. HY/2009/11 ¡V Central ¡V Wanchai Bypass, North Point Reclamation

6.4.1.        Referring to the exceedances shown in Table 5.9, the occasionally action and limit level exceedances of turbidity and suspended solid were recorded at C8 and C9. Stations WSD15 had one SS exceedance recorded in this month.

6.4.2.        Since there were numerous unknown outfalls from the nearby coastal area closed to the cooling intakes C8 and C9, it causes the potential for accumulation of pollutants near the intakes and may lead to potential water quality deterioration at the seawater intake points. Most of the turbidity and SS exceedances were concluded as not project related exceedances excluded the exceedance at C8 on 30 December 2010.

6.4.3.        Turbidity and SS exceedances at C8 on 30 December 2010 were recorded.  Due to intake owner's constraint, delay was experienced in the re-provision of modified frame-type silt screen to protect City Garden intake against potential impact arising from the dredging works and accumulation of discharge and pollutants from nearby outfall adjacent to the intake. The exceedances were confirmed related to HY/2009/11 contractor difficulties in the provision of frame type silt screen.  Contractor enhanced mitigation measures with a double layer silt curtain on 7 January 2011. No further exceedance was recorded after installation of double layer silt curtain. Close monitoring on contractor mitigation and the variation of water quality results will be maintained. Contractor will further liaise with the owner on the re-provision of the frame-type silt screen.

6.4.4.        Reviewed the trend of overall results at all monitoring stations nearer the marine work area, the SS exceedance recorded at WSD15 while low SS value was recorded at the stations near the marine work area without exceeded the action and limit level. Thus, this SS exceedance was considered not related to the Project works.

Contract no. HK/2009/01 - Wan Chai Development Phase II ¡V Central ¡VWanchai Bypass at HKCEC

6.4.5.        Referring to all exceedances recorded at WSD7, WSD19 and WSD20, there was no exceedance recorded at the monitoring stations nearer the marine work area for Contract HK/2009/01. Those exceedances were considered as not related to the Project works.

6.4.6.        One SS exceedance recorded at C4w on 24 January 2011. Investigation found that the condition of silt screen and silt curtain was in proper condition and low daily dredging rate was complied with EP condition. No exceedance was recorded at the C3 which is the nearest monitoring station near the dredging work area. It is concluded as not related Project.

Contract no. HK/2009/02 - Wan Chai Development Phase II ¡V Central ¡V Wan Chai Bypass at WanChai East

6.4.7.        One turbidity and SS exceedance was recorded at C5e on 8 January 2011. Investigation found that the condition of silt screen and silt curtain was in proper condition and daily dredging rate at submarine sewage pipeline was complied with EP condition. Besides, the additional measure of additional silt curtain is deployed to protect the monitoring stations C5e. Thus, the exceedance was considered due to natural variation and not related to the Project.

Contract no. HY/2009/15 - Central-Wanchai Bypass ¡V Tunnel (Causeway Bay Typhoon Shelter Section)

6.4.8.        No exceedance was recorded in the reporting month.

6.4.9.        Summary for notification of exceedances can be referred to Appendix 6.2.

 

6.5               Review of the Reasons for and the Implications of Non-compliance

6.5.1.        There was no non-compliance from the site audits in the reporting period. The observations and recommendations made in each individual site audit session were presented in Section 8.

6.5.2.        No project-related non-compliance from monitoring was recorded in the reporting month.

 

6.6               Summary of action taken in the event of and follow-up on non-compliance

6.6.1.        There was no particular action taken since no project-related non-compliance was recorded from the site audits and environmental monitoring in the reporting period.

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.        From the Monthly EM&A report (December 2010) of Central Reclamation Phase III (CRIII) the key works in January 2011 are as follows:

¡P          Architectural works and commissioning tests at Pier 7;

¡P          Wet Trades and Architectural works at the Lower, middle and upper decks of Pier 8 and steel frame for roof glazing;

¡P          CTB installation of clock into the clock tower, architectural and E & M works & link bridge construction;

¡P          Piling (Socket H-Pile & Rock Anchors) and tie beam works at Public Pier West;

¡P          Testing and Commissioning of Pump Station P5.1;

¡P          Electricity Cable laying to Piers and to ESBs S11.1 & S11.2 (temporary);

¡P          MYS Footbridge ¡V cross head construction and steel frame fabrication (off Site);

¡P          MYS storm drainage, sewers, watermains and roadworks to pier areas;

¡P          MYS Laying of 800 dia. Cooling Main;

¡P          MYS Existing Culvert F ¡V preparation for desilting and stabilisation works for culvert.

¡P          MYS Culvert F Extension ¡Vpreparation for piling for Bay 1;

¡P          General filing works above +2.5mpd in IRAE;

¡P          In situ work to caisson and pumping stations¡¦ seawall copings;

¡P          Internal E&M works to IRAE pump stations;

¡P          ESB (S8.1 & S9.1) ¡VInstallation of generators and cabling works;

¡P          ESB (S11.1 & S11.2) ¡VABWF and E&M works;

¡P          Culvert J piling and structural works;

¡P          Bored piling at Eastern Seawall and;

¡P          Cooling water main construction in Lung Wui Road, Edinburgh Place and in IRAE.

 

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 activities under Wan Chai Development Phase II were the dredging and filling works at North Point Reclamation Shoreline Subzone (NPR2E) and (NPR1) respectively, the dredging and filling at submarine sewage pipline and Wan Chai Reclamation Shoreline Subzone (WCR1) respectively, dredging at HKCEC1 and cross harbour water mains and dredging at TCBR1W, TCBRAW, TPCWAE and TCBR1E for seawall construction 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. As only one project-related exceedance was recorded in North Point district that is far away from the work area of CRIII, 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.

8.         Environmental Site Audit

8.0.1.        During this reporting month, weekly environmental site audits were conducted for Contracts no. HY/2009/11, HK/2009/01, HK/2009/02 and HY/2009/15. No non-conformance was identified during the site audits.

9.0.4.        An incident of split hopper barge named Shun Tat 11 (Licence no. B21623V) for the Contract no. HK/2009/01 was recorded at the location near Cross Harbour Water Mains marine work zone on 24 January 2011.  The ballast tank on the port side of the split hopper barge was flooded with water. The split hopper barge was towed back to the dredging zone within a short period and immediately opened its hopper to dump the sediment back to the same dredging trench. It is suspected that the hull on the port side might be broken causing ingress of seawater into the ballast tanks. Meanwhile, the barge has been demobilized from the site and currently anchored at To Kwa Wan Typhoon Shelter. The emergency dumping was notified to EPD at 10:00a.m. on 24 January 2011. This barge will not be deployed to the site under HK/2009/01 to dispose the dredged sediment until it has been repaired and inspected by the competent surveyor. The incident will be kept in view for determining further follow up and remedial measures.
