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.
Design and Construction of Central ¡V 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:
¡P
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);
¡P
The Central Interchange near the Rumsey Street Flyover to provide road
connections to the Central area;
¡P
Tunnel control buildings and ventilation buildings;
¡P
Slip roads to connect the CWB to the local road system in the Wan Chai
North and Causeway Bay area;
¡P
Associated road lighting, road signing, traffic control and surveillance
system; and
¡P
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
3.1.3.
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.
3.1.4.
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:
¡P
One set of
measurements between 0700 and 1900 hours on normal weekdays.
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:
¡P
One set of
measurements between 0700 and 1900 hours on normal weekdays.
¡P
One set of
measurements between 1900 and 2300 hours on normal weekdays and 0700 and 2300
hours on public holidays.
¡P
One set of
measurements between 2300 and 0700 hours on next day on everyday.
3.1.6.
If
construction works are extended to include works during the hours of 1900 ¡V
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
3.1.7.
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.
3.1.8.
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.
3.1.9.
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 may 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
3.2.1. The air quality monitoring stations for the Project

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 and
the of Central-Wanchai Bypass at Wanchai West at the Central Reclamation Phase
III area, no works was conducted in the reporting period. In addition, with
reference to the Final EM&A Reports of EP-122/2002/E,
EP-356/2009, FEP-01/356/2009, FEP-02/356/2009, FEP-03/356/2009,

FEPs were completed. As such, it is
considered that there were no cumulative construction impact due to the Central Reclamation Phase III (CRIII)
was not anticipated.
7.0.4.
The major
construction activities under Central-Wan Chai Bypass and Island Eastern Corridor
Link Projects was completed on 31 August 2022.
