stipulated in the EM&A Manual of the approved Environmental Impact
Assessment (EIA) Report for Wan Chai Development phase II and Central-Wan Chai
Bypass (Register No.: AEIAR-125/2008) and in the EM&A Manual of the
approved EIA Report for Central-Wan Chai Bypass and Island Eastern Corridor
Link (Register No. AEIAR-041/2001).
1.1.2.

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.

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.

impact monitoring for
odour patrol
3.2.12 Odour patrols along the
shorelines of Causeway Bay Typhoon Shelter and ex-Wan Chai Public Cargo Working
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.
Water Quality Monitoring Stations
3.3.3. Water quality monitoring was undertaken at WSD salt
water intakes and cooling water intakes along the seafront of the Victoria
Harbour. The proposed water quality
monitoring stations of the Project are shown in Table 3.3 and Figure 3.1. Appendix 3.1 shows the established
Action/Limit Levels for the monitoring works.

7.0.1. According
to Condition 3.4 of the EP-356/2009, this section addresses the relevant
cumulative construction impact due to the concurrent activities of the current
projects including the Central Reclamation Phase III, Central-Wanchai Bypass
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, dismantling of temporary landing step and junction
modification were performed in the 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 Development Phase II
were road and drains construction and TWCR4 reinstatement at Wan Chai. The
major construction activities under Central-Wan Chai Bypass and Island Eastern
Corridor Link Projects were ventilation building ABWF works and junction modification
at Central; road works, drainage improvement work, utility diversion works and landscape
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. No significant air impact from
construction activities was anticipated in the reporting period. Besides, no
project related exceedance was recorded during the air and noise environmental
monitoring events in the reporting period. Thus, it is evaluated that the
cumulative construction impact from the concurrent projects including Central
Reclamation Phase III (CRIII), Wan Chai Development Phase II (WDII),
Central-WanChai Bypass (CWB), Island Eastern Corridor Link projects (IECL) was
insignificant.
8.0.1. The EM&A programme was carried out in
accordance with the EM&A Manual requirements, minor alterations to the
programme proposed were made in response to changing circumstances.
