Section 8 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.

Due to the multi-contract nature of the Project, the status of permits
and/or licences under the individual contract(s) are presented as below:
Contract no. HK/2010/06 – Wan Chai
Development Phase II – Central – Wan Chai Bypass over MTR Tsuen Wan Line under

2.3.4
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.

between 0700 and 1900 hours on normal weekdays. For all other time periods, Leq
(5 minutes) shall be employed for comparison with the Noise Control
Ordinance (NCO) criteria.
Supplementary information for data auditing, statistical results such as L10
and L90 shall also be obtained for reference.
3.1.3. Noise monitoring shall be
carried out at all the designated monitoring stations. The monitoring frequency
shall depend on the scale of the construction activities. The following is an
initial guide on the
regular monitoring frequency for each station on a weekly basis when noise
generating activities are underway:
·
one
set of measurements between 0700 and 1900 hours on normal weekdays.
3.1.4. If construction works are extended to include works
during the hours of 1900 – 0700 as well as public holidays and Sundays,
additional weekly impact monitoring shall be carried out during respective
restricted hours periods. Applicable permits under NCO shall be obtained by the
Contractor.
3.1.5. Real time noise shall be carried out at the
designated monitoring stations. The following is an initial guide on the

as shown in Figure 3.1 to detect any odour at
the concerned hours (afternoon is preferred for higher daily temperature).
3.2.14 The qualified person will use the nose (olfactory
sensor) to sniff odours at different locations. The main odour emission sources
and the areas to be affected by the odour nuisance will be identified.
3.2.15 The perceived odour intensity is to be divided into
5 levels which are ranked in the descending order as follows:
·
0 -
Not detected. No odour perceived or an odour so weak that it cannot be easily
characterized or described;
·
1 -
Slight Identifiable odour, and slight chance to have odour nuisance;
·
2 -
Moderate Identifiable odour, and moderate chance to have odour nuisance;
·
3 -
Strong Identifiable, likely to have odour nuisance;
·
4 -
Extreme Severe odour, and unacceptable odour level.
3.2.16 The findings including odour intensity, odour
nature and possible odour sources, and also the local wind speed and direction
at each location will be recorded. In addition, some relevant meteorological
and tidal data such as daily average temperature, and daily average humidity,
on that surveyed day will be obtained from the Hong Kong Observatory Station
for reference. The Action and Limit levels for odour patrol are shown in Appendix 3.1.
3.3.1. The EIA Report has identified that the key water
quality impact would be associated with the dredging works during the
construction phase. Marine water quality
monitoring for dissolved oxygen (DO), suspended solid (SS) and turbidity is
therefore recommended to be carried out at selected WSD flushing water
intakes. The impact monitoring should be
carried out during the proposed dredging works to ensure the compliance with
the water quality standards.
