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
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
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,
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.

different locations. The main odour emission sources and the areas to be
affected by the odour nuisance will be identified.
4.2.15. 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.
4.2.16.
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 6.1.
4.2.17. The
qualified odour patrol member has individual n-butanol thresholds complied with
the requirement of European Standard Method of Air Quality – Determination of
Odour Concentration by Dynamic Olfactometry (EN13725) in the range of 20 to 80

month.
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. According
to the Monthly EM&A report (April 2013) of Central Reclamation Phase III
(CRIII), Installation of cable wall at PLA berth, footpath construction and Modification to the junction of Road D8
and Road P2 were performed in the May 2013 reporting month. The water quality
monitoring was completed in October 2011 and no Project-related exceedance was
recorded for air and noise monitoring.
It can be concluded that cumulative construction impact due to the
concurrent activities of the current projects with the Central Reclamation Phase
III (CRIII) was insignificant
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 activity under Wan Chai
Development Phase II were marine works at HKCEC areas, cross-harbour
Watermains, Fresh Watermains and Cooling Watermains Installations, tunnel works
at Wan Chai East, ELS work at TS4 and deep excavation at TPCWAE TCBR1W. Excavation
and tunnel works at Central Interchange, ELS and box culvert construction at
North Point area. The major environmental impact was water quality impact at
7.0.4. The major
environmental impacts generated from tunnel works at Central and tunnel works
at Wan Chai East, IECL and Causeway Bay Typhoon Shelter were undertaken in the
reporting month. No significant air impact from construction activities was
anticipated in the reporting month. Besides, there was works-related limit
level exceedance during water quality monitoring event in the reporting month
and rectification measures have been implemented by contractor. Thus, it is
evaluated that the cumulative construction impact from the concurrent projects
including Wan Chai Development Phase II was insignificant.
8.0.1. During
this reporting month, weekly environmental site audits were conducted for

10.0.8.
Based on the safety concern when external façade refurbishment was
conducted by contractor employed by Provident Centre (C9) between 9 January
2012 to 30 July 2012 which caused to the inaccessibility of sampling either
land and marine since 3 Feb 2012, there is a fine adjustment of the sampling
location of water quality monitoring at C9 since 10 March 2012 to the closest
accessible point prior to the completion of the external façade refurbishment
work.
10.0.9.
Due to the access of water monitoring station at WSD19 was blocked by
