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.

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
regular monitoring frequency for each station on a 24 hours daily basis when
noise generating activities are underway:
·
One set of measurements between 0700 and 1900 hours
on normal weekdays.
·
One set of measurements between 1900 and 2300 hours
on normal weekdays and 0700 and 2300 hours on public holidays.

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.
3.3.2.
The
updated EM&A Manual for EP-356/2009 (Version in March 2011) is approval by
EPD on 29 April 2011. As such, the Action Level and Limit Level for the wet
season (April – September) will be effected and applied to the water quality
monitoring data from 30 April 2011.

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 Final EM&A Report of Central Reclamation Phase III (CRIII) for
Contract HK 12/02, the major construction activities were completed by end of
January 2014 and no construction activities were undertaken thereafter and 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 Central-Wanchai Bypass at Wanchai West at the Central
Reclamation Phase III area, no works was conducted in May 2020 reporting
period. In view of the above, the cumulative construction impact due to the
Central Reclamation Phase III (CRIII) was not anticipated.
7.0.4. According to the
construction programme of Wan Chai Development Phase II, Central-Wan Chai
Bypass and Island Eastern Corridor Link projects, no construction works under
Wan Chai Development Phase II was conducted at Wan Chai. The major construction
activities under Central-Wan Chai Bypass and Island Eastern Corridor Link
Projects were ventilation building ABWF works at Central; road works, drainage
improvement work, utility diversion works and landscape works at Victoria Park;
bridge noise enclosure installation works, road works, drainage works, soft
landscape works and ventilation building ABWF work at North Point area in the
reporting period. In addition, other non-Wan Chai Development Phase II,
Central-Wan Chai Bypass and Island Eastern Corridor Link projects were observed
undertaken at Wan Chai North and North Point area.
7.0.5. No
significant air and noise impact from construction activities was anticipated
in the reporting period. Besides, no project related exceedance was recorded
during the air and noise environmental monitoring events in the reporting
period. Thus, it is evaluated that the cumulative construction impact from the
concurrent projects including Central Reclamation Phase III (CRIII), Wan Chai
Development Phase II (WDII), Central-WanChai Bypass (CWB), Island Eastern
Corridor Link projects (IECL) was insignificant.
8.0.1. The EM&A programme was carried out in
accordance with the EM&A Manual requirements, minor alterations to the
programme proposed were made in response to changing circumstances.
8.0.2.
There was no non-compliance from the site
audits in this reporting quarter.
8.0.3.
One complaint made to EPD on 18 December 2019
was received by ET on 12 March 2020. The complainant reported that oil slick
was spotted on sea surface outside Expo Drive East next to the Hong Kong
Convention and Exhibition Centre on 18 December 2019.
ET confirmed
with the Resident Site Staff that no construction activity was undertaken
around the concerned location under Contract HK/2009/02 on 18 December 2019 and
the coastline of the concerned area has already been handed over to other
party.
8.0.4. The construction programmes of individual contracts
