Section 10   Conclusion
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.
2.2.1. 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:
 -
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
 -
Reprovisioning / protection of the existing
facilities and structures affected by the land formation works mentioned above
 -
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
 -
Upgrading of hinterland storm water drainage
system and sewerage system, which would be rendered insufficient by the land
formation works mentioned above
 -
Provision of the ground level roads,
flyovers, footbridges, necessary transport facilities and the associated
utility services
 -
Construction of the new waterfront promenade,
landscape works and the associated utility services
 -
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.

2.3.1. Due to the multi-contract
nature of the Project, there are a number of contracts sub-dividing the whole
works area into different work areas to be commenced. Contractors of individual contracts will be required by the EP
holder to apply Further Environmental Permits (FEP) such that the impact
monitoring stations are sub-divided accordingly to facilitate the
implementation of EM&A programme and to streamline the EM&A reporting
for individual FEP holders correspondingly.

Confined Marine Disposal marine sediment disposed in the reporting month. The
maximum dredging rate in North Point Shoreline Zone is 3000m3 per
day in the reporting month, which is complied with the criteria listed in Table
5.10 of EIA Report Register No. AEIAR-125/2008.
6.0.1.
The Event Action Plan for construction noise,
air quality and water quality are presented in Appendix 6.1.
6.1.1.
One limit level exceedance was recorded in the
restricted hour on 8 April 2010. Major noise source was noted from the traffic
noise of the Island Eastern Corridor during the measurement. After analysis of contractor’s working
procedure, well work practical of the dredging work was complied with the
conditions under valid Construction Noise Permit no. GW-RS0119-10 during the
measurement. No exceedance was recorded in the next restricted hour monitoring.
Therefore, it was considered as invalid exceedance.
6.2.1.
No air monitoring was conducted in this
reporting period.
6.3.1. For
the suspended solid, total twelve action level exceedances and six limit level
exceedances were recorded in the reporting month. The details of exceedances
are as follows:
 -
Five action level exceedances were recorded
at C8 during mid-flood on 30 March and 16 and 26 April 2010 and during mid-ebb
on 7 and 10 April 2010;
 -
Six action level exceedances were recorded at
C9 during mid-food on 28 March, 5 and 10 April 2010 and during mid-ebb on 7, 10
and 14 April 2010;
 -
One limit level exceedance was recorded at
WSD17 during mid-flood on 26 April 2010;
 -
Two limit level exceedances were recorded at
C8 during mid-flood on 28 March and 12 April 2010; and
 -
Four limit level exceedances were recorded at
C9 during mid-flood on 30 March, 12, 16 and 26 April 2010.
6.3.2. For
the turbidity, total three action level exceedances and six limit level
exceedances were recorded in the reporting month. The details of exceedances are as follows:
 -
One action level exceedance was recorded at
C8 during mid-ebb of 12 April 2010;
 -
Two action level exceedances were recorded at
C9 during mid-flood on 10 and 19 April 2010;
 -
Three limit level exceedances were recorded
at C8 during mid-flood on 12, 16and 26 April 2010; and
 -
Three limit level exceedances were recorded
at C9 during mid-flood of 5, 16 and 26 April 2010.
6.3.3.
The action and limit level exceedances of
turbidity and suspended solid were recorded at C8 and C9. Major exceedances
were occurred during the mid-flood tide in the water quality monitoring.
Investigation was found that the numerous unknown outfalls from the nearby
coastal area enclosed by the silt screen at C8 and C9. It causes the potential for accumulation and
trapping of pollutants behind the silt screens and may lead
to potential water quality deterioration at the seawater intake points. Contractor
was reminded to avoid the pollutant and refuse entrapment problems.
Besides, regular
maintenance of the silt screens and refuse collection shall be performed at the
monitoring stations at regular intervals on a daily basis.
6.3.4.
The limit level exceedance was recorded at
WSD17 on 26 April 2010. No muddy boom
was observed during the water monitoring. The value is within the tolerance of
the baseline water quality range. Reviewed the next consecutive monitoring
data, no exceedance was recorded. As such, it is concluded as non-project
related exceedance. Summary for notification of exceedances can be referred to Appendix 6.2.
6.4.1.
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.
6.4.2.
No project-related non-compliance from
monitoring was recorded in the reporting month.
6.5.1.
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.
7.0.1.
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,
Central-Wan Chai Baypass and Island Eastern Corridor Link projects.

7.0.3.
According to the construction programme of Central-Wan
Chai Baypass and Island Eastern Corridor Link projects, the major construction activity
under Wan Chai Development Phase II was the dredging work at North Point Reclamation
Stage 1 in the reporting month. The major environmental impact was water
quality impact at North Point.  /span>No
construction activities were undertaken in the Central-Wan Chai Baypass and
Island Eastern Corridor Link projects.
7.0.4.
The major environmental impacts generated from
the Central Reclamation Projects were located along the coastline of Central
and Admiralty while only dredging work at North Point Reclamation Stage 1 was
in operation in this reporting month. Beside,
water quality mitigation measures were properly in place for the dredging works
under HY/2009/11 in this reporting month. No project –related exceedance were
recorded. Thus, it is evaluated that the cumulative construction impact from
the concurrent projects including Wan Chai Development Phase II and Central Reclamation
was insignificant.
