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
Designed Project (DP) under the Environmental Impact Assessment Ordinance (Cap.
499) (EIAO). The Environmental Impact
Assessment (EIA) Reports for Central-Wan Chai Bypass and
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
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
·
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.

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 July be accepted as valid only if the calibration level from
before and after the noise measurement agree to within 1.0 dB.

7.0.3. According to the construction programme of Wan Chai
Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link
projects, the major construction activity under Wan Chai Development Phase II was
the seawall block construction at TCBR1w, reclamation works of HKCEC Water
Channel, dredging for submarine outfall pipe, Advanced piling works at FEHD
Whitfield Depot, Central Interchange, cross-harbour water mains and marine
pre-drilling in the reporting month. The major environmental impact was water
quality impact at
7.0.4. The major environmental impacts generated from advanced piling works at FEHD
Whitfield Depot were
undertaken and sheet piling, pre-drilling
and sheet piling works at Central and tunnel works at Wan Chai East in the reporting month. No
significant air impact was anticipated in the reporting month. However, one
Limit Level exceedance was recorded during construction noise monitoring in
relation to Contract no. HY/2009/18 for the project Central-Wan Chai Bypass in
July 2011. Mitigation measures were implemented shortly by the Contractor
according to the Event and Action and no further exceedance was recorded
afterwards. Thus, it is evaluated that the cumulative construction impact from
the concurrent projects including Wan Chai Development Phase II was mainly
insignificant.
