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 Designated 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.
Design and Construction of Central – Wan Chai
Bypass and Island Eastern Corridor Link under the Project involves the
construction and operation of a trunk road and its road tunnel more than 800m
in length between portals that is shown at Figure 2.1.
2.2.2.
The study area encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:
·
A dual
three-lane trunk road, approximately 4.5 km in length, and tunnel approximately
3.7 km in length defined from the connection with the existing Rumsey Street
Flyover in Central, through to a connection with the existing Island Eastern
Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);
·
The
Central Interchange near the Rumsey Street Flyover to provide road connections
to the Central area;
·
Tunnel
control buildings and ventilation buildings;
·
Slip
roads to connect the CWB to the local road system in the Wan Chai North and
Causeway Bay area;
·
Associated
road lighting, road signing, traffic control and surveillance system; and
·
Other
associated works.
2.2.3.
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, 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 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.

Noise Monitoring Parameters, Frequency
and Duration
4.1.3.
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.
4.1.4.
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.
4.1.5.
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 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.
4.1.6.
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.
Monitoring Equipment
4.1.7.
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.
4.1.8.
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.
4.1.9.
The sound level meter shall be checked using
an acoustic calibrator generating a known sound pressure level at a known
frequency before deployment to the site and during each site visit.
Measurements will be accepted as valid only if the calibration level from
before and after the noise measurement agree to within 1.0 dB.
Air Quality Monitoring Stations
4.2.1.
The air quality monitoring stations for the
Project are listed and shown in Table 4.3 and Figure 4.1. Appendix 4.1 shows the established

7.0.1.
According to Condition 3.4 of the
EP-364/2009/H, this section addresses the relevant cumulative construction
impact due to the concurrent activities of the current projects including the
Central Reclamation Phase III (CRIII), Wan Chai Development Phase II (WDII),
Central-WanChai Bypass (CWB), Island Eastern Corridor Link projects (IECL) and
Wan Chai Development Phase II – Central – Wan Chai Bypass at Wan Chai East (CWB
Tunnel).
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. As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting period.
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 November 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 modification works at Central; seabed reinstatement
at Causeway Bay, drainage improvement work and utility diversion 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.
As relevant site mitigation measures for air
quality and construction noise were implemented, no significant air quality
impact and noise impact from construction activities was concluded in the
reporting period. Besides, no project related exceedance was
recorded in the reporting period. Thus, it is evaluated that
the cumulative construction impact from the concurrent projects including Wan
Chai Development Phase II (WDII), Central-WanChai Bypass (CWB), Island Eastern
Corridor Link projects (IECL) was insignificant.
8.0.1.
