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.

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.

the demolition of Ex-harbour Road Sports Centre, the respective noise
monitoring station M1a- Harbour Road Sports Centre were finely adjusted on 16
and 25 May 2017 and thereafter to the Footbridge at Harbour Road Sports Centre
for noise monitoring.
Noise Monitoring Parameters, Frequency and Duration
3.1.2. The construction noise level
shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq
(30 minutes) shall be used as the monitoring parameter for the time period 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
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.
·
One set of
measurements between 2300 and 0700 hours on next day on everyday.
Monitoring Equipment
3.1.6. As
referred to in the Technical Memorandum ™ issued under the NCO, sound level
meters in compliance with the International Electrotechnical
Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1)
specifications shall be used for carrying out the noise monitoring. Immediately
prior to and following each noise measurement the accuracy of the sound level
meter shall be checked using an acoustic calibrator generating a known sound
pressure level at a known frequency. Measurements may be accepted as valid only
if the calibration level from before and after the noise measurement agree to
within 1.0 dB.
3.1.7. Noise
measurements shall not be made in fog, rain, wind with a steady speed exceeding
5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall be checked with
a portable wind speed meter capable of measuring the wind speed in m/s.
Air Quality Monitoring Stations
3.2.1. The air monitoring stations for the Project are
listed and shown in Table 3.2 and Figure 3.1. Appendix 3.1 shows the established Action/Limit Levels for the
monitoring works.

Area when there is temporary reclamation in Causeway Bay Typhoon Shelter and/or in the ex-Wan Chai Public Cargo
Working Area, or when there is dredging of the odorous sediment and slime at
the south-western corner of the Causeway Bay Typhoon Shelter. Odour patrols
will be carried out at bi-weekly intervals during July, August and September by
a qualified person of the ET who shall:
·
be at least 16 years
of age;
·
be free from any
respiratory illnesses; and
·
not be allowed to
smoke, eat, drink (except water) or use chewing gum or sweets 30 min
·
before and during
odour patrol
3.2.13 Odour patrol shall be conducted by independent
trained personnel / competent persons patrolling and sniffing around the shore
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.
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.

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 include roadworks, drainage, seawall
coping and junction modification were performed in February 2019 reporting
period. As
no project related exceedance were recorded during the reporting period,
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) was considered as
insignificant.
7.0.4. 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
