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 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.
2.3.2.
In the reporting period, all the contracts were commenced and
contract no. 04/HY/2006 had been completed. The details of individual

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.

A noise impact complaint was
received by ET on 5 March 2012 (ICC Ref. No.: 1-344632511 dated on 3 March 2012, forwarded by RSS). The complaint was reported by
the resident of Harbour Heights that excessive noise from construction sites
of CWB was observed outside Harbour Heights from Monday to Saturday before 8am.
The plants were frequently turned on before 7:30am creating nuisance. The
complainant requested a speedy follow-up and reply from relevant department.
6.0.5.
ET confirmed with the Resident Site Staff
that PME for diaphragm wall construction started to operate at about
7:30am whilst the other PME, including those for land bored piling work,
started to operate after 8am.
6.0.6.
After reviewing the results of noise monitoring (M4b), no
exceedance was recorded during daytime period and the noise level was below 75dB(A). Site
inspection for HY/2009/19 was conducted on 7 March 2012. The condition of noise
mitigation measures near Harbour Heights was found satisfactory. RSS confirmed that no operation was active
before 7:00am everyday. The suspected nuisance was to be considered caused by
the PME for diaphragm wall construction. A surprise check was performed on 13
March 2012 by RSS. It was found that no noisy PME was in operation by
Contractor of HY/2009/19 before 8am, and the construction noise level was
minimal and not disturbing. The noise level and operation time both complied
with statutory requirements set up in NCO.
6.0.7.
Complainant called ICC on 8 March 2012 to confirm HyD has
provided a response. No further complaint was received after the response.

6.0.8.
A noise impact complaint was
received by ET on 5 April 2012 (ICC Ref. No.: 1-349030623 dated 5 April 2012, forwarded by RSS). The complaint was reported by an anonymous complainant that excessive noise from construction sites of CBTS
was observed daily before 7:30am except on public holidays, and the noise
source was mainly from piling works.
The complainant requested that construction works should start after
8:30am to avoid nuisance to nearby residents and a speedy follow-up and reply.
6.0.9.
ET confirmed with the Resident Site Staff
that no piling works were performed during the concerned period.
6.0.10. After
reviewing the results of noise monitoring (M2b and M3a), no exceedance was
recorded during daytime period and the noise level was below 75dB(A). Site inspection
for HY/2009/15 was conducted on 10 April 2012.
The condition of noise mitigation measures around CBTS was found
satisfactory. RSS confirmed that no pilings were performed during the concerned
period. The major works included
drilling, diaphragm wall construction and excavations.
6.0.11. HyD made a reply to the complainant on 16 April 2012 via
1823. HyD replied that the current
works at CBTS were drilling, diaphragm wall construction and deep excavations.
In order to minimize the noise generated from the above works, the Contractor had erected temporary
noise barriers and provided noise blankets on plants.
RSS would continue to work with the Contractor
on the effectiveness of the environmental mitigation measures implemented on
site. No further
complaint was received after the response.
6.0.12. A noise impact complaint was received by ET on 17 April 2012 /span>(ICC Ref. No.: 1-351021108 dated 15 April 2012, forwarded by RSS). The complaint was reported by
Ms. Law, a resident of Fu Lee Loy Mansion that noise generated from a HyD project that is located at the
connection point of CWB and IEC affecting nearby residents. Lately during the middle of the night
(around 00:00 to 05:00), low frequency noise, which possibly came from the
operating power generator and the barges which were parked along the Oil Street
work site, were making a nuisance to the complainant and residents nearby. The complainant requested that relevant
department should follow-up.
6.0.13. ET confirmed
with the Resident Site Staff that there was no operation of power generators
for HY/2009/19 and HY/2009/17 (HY/2009/11 had no physical work on site) during
the concerned period. Although there were a few barges mooring at the
seafront of HY/2009/19, they were not in operation and hence no operational
noise would be emitted.
6.0.14. After
reviewing the results of noise monitoring (M4b and M5b), no exceedance was
recorded during day time period and the noise level was below 75dB(A). Site
inspection for HY/2009/19 was conducted on 18 April 2012. The condition of noise mitigation measures
near Harbour Heights were found satisfactory. RSS confirmed that no operation
of power generators for HY/2009/19 and HY/2009/17 (HY/2009/11 had no physical
work on site) during the concerned period. Although there were a few
barges mooring at the seafront of HY/2009/19, they were not in operation and
hence no operational noise would be emitted.
6.0.15. HyD made a reply to the complainant on
30 April 2012 via email. HyD replied
that the current works near Oil Street, North Point, included CWB tunnel works,
IEC connections and associated foundation works. According to RSS records, no operations were performed during the
early hours of March and April at Oil Street and the waterbody nearby, and so
it was believed that the noise nuisance was not generated from the CWB
project. Despite that, RSS would continue to monitor the Contractor on the operations and
effectiveness of the environmental mitigation measures implemented on site, as
not to affect daily life of local residents nearby. No further complaint was received after the response.
