  1. Turbidity and SS exceedances at C6 on 7 February 2011 at mid-flood and mid-ebb tides were recorded. Further investigation on 9 Feb 2011 revealed the crack on the silt screen at C6. A crack on silt screen structure leaded to ingress of unscreened polluted water directly to the intake created by frequent vessel movement on shallow water in Causeway Bay Typhoon Shelter. The exceedances were confirmed due to the silt screen defect.

 

  1. The turbidity exceedances were recorded at C5e, C5w and WSD21 on 11 Feb 2011 at mid-flood when the local buckling of western sheetpile temporary seawall at WCR1 was recorded in the morning of 11 February 2011. These exceedances were confirmed due to the buckling of western sheetpile temporary seawall. Contractor had immediately installed the additional silt curtain surround the location of buckling seawall on that day.

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.

6.3.1.        No exceedance was recorded in the reporting month.

 

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 two 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. The recorded turbidity and SS exceedances were concluded as not project related.

6.4.3.        Reviewed the trend of overall results at all monitoring stations nearer the marine work area, the SS exceedances 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

6.4.4.        One SS exceedance recorded at C3 on 21 February 2011.

Investigation found that no abnormal observation was recorded during the monitoring and the exceedance was concluded not due to the Project works.

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

6.4.5.        The turbidity exceedances were recorded at C5e, C5w and WSD21 on 11 Feb 2011 at mid-flood when the local buckling of western sheetpile temporary seawall at WCR1 was recorded in the morning of 11 February 2011. These exceedances were confirmed due to the buckling of western sheetpile temporary seawall. Contractor had immediately installed the additional silt curtain surround the location of buckling seawall on that day.

6.4.6.        Occasional turbidity and SS exceedances recorded at C5e, C5w and WSD21 were found in the reporting month. Investigation found that the silt screen and silt curtain were in proper condition and daily dredging rate at submarine sewage pipeline was complied with FEP condition. The exccedances might be caused by the natural variation or accumulation of fine particles and debris in the vicinity of monitoring stations. Contractor was recommenced to clear the debris more frequently in daily clearance if necessary. 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)

6.4.7.        Turbidity and SS exceedances at C6 on 7 February 2011 at mid-flood and mid-ebb tides were recorded. Further investigation on 9 Feb 2011 revealed the crack on the silt screen at C6. A crack on silt screen structure leaded to ingress of unscreened polluted water directly to the intake created by frequent vessel movement on shallow water in Causeway Bay Typhoon Shelter. The exceedances were confirmed due to the silt screen defect.

6.4.8.        Occasional turbidity and SS exceedances recorded at C6 and C7 were found in the reporting month. Investigation found that the daily dredging rate at TCBR was complied with FEP condition.  Proper deployed silt curtain and no abnormal condition on working practices were found when the exccedances recorded. Thus, the exceedance was considered due to natural variation in the Causeway Bay Typhoon Shelter and not related to the Project.

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

6.6               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 (January 2011) of Central Reclamation Phase III (CRIII) the key works in February 2011 are as follows:

¡P          Type A filling in FRAW and FRAE above +2.5mPD;

¡P          General filling works above +2.5mPD in IRAE;

¡P          Surcharging in FRAW and FRAE;

¡P          Construction of cantilever slab at caisson;

¡P          Base slab, wall and roof construction at Culvert F;

¡P          Construction of storm and foul drainage and gullies in hinterlands for Road P2, Road D7, and Road D9;

¡P          Construction of GPO boundary wall;

¡P          Construction of PLA boundary wall;

¡P          Construction of Promenade enhancement works;

¡P          Construction of buildings at PLA berth;

¡P          Road P2 Underpass ramp structures;

¡P          Precasting for retaining wall (offsite);

¡P          Installation of cooling mains discharge pipes in FRAE and FRAW;

¡P          Bulk excavation to formation level at CWB works;

¡P          Construction of CWB structure; and

¡P          Disposal of material off-site to Government fill banks

 

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 (Submarine sewage pipeline) respectively, dredging at HKCEC3W and cross harbour water mains and dredging at TCBR 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 the recorded project-related exceedance in Causeway Bay Typhoon Shelter and Wan Chai that was localized interference and far away from the work area of 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.
