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 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

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.
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
4.1.6.
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.
4.1.7.
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.
Air Quality Monitoring Stations
4.2.1.
The air monitoring stations for the Project are
listed and shown in Table 4.3 and Figure 4.1. Appendix 4.1 shows the established
Action/Limit Levels for the monitoring works.

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
4.2.13. Odour
patrol shall be conducted by independent trained personnel / competent persons
patrolling and sniffing around the shore as shown in Figure 4.1 to detect any odour at
the concerned hours (afternoon is preferred for higher daily temperature).
4.2.14. 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.
4.2.15. 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.
4.2.16.
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 6.1.
4.2.17.
The qualified odour patrol member has individual
n-butanol thresholds complied with the requirement of European Standard Method
of Air Quality – Determination of Odour Concentration by Dynamic Olfactometry
(EN13725) in the range of 20 to 80 ppb. The certificate for the qualified odour
panel member is shown in Appendix
4.2.
4.3.1.
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.
4.3.2.
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.

Remarks: - The cessation of seawater intake operation for C6 was confirmed on 17 May 2011, the water monitoring at C6 was then terminated since 17 May 2011.
5.4.6.
The
enhanced water quality monitoring at C6, C7, Ex-WPCWA-SW and Ex-WPCWA-SE was
commenced on 13 January 2011. No project-related exceedance was recorded in the daily SS
monitoring and 24 hours turbidity monitoring.
5.4.7.
As
per the meeting with the representative of Excelsior Hotel and World Trade
Centre on 17 May 2011, they confirmed that the seawater intake for The
Excelsior was no longer in use and replaced by the connected permanent water
supply from WSD pipelines since 11 January 2011. Thus, the impact water quality
monitoring for the cooling intake - C6 was terminated effective from 26 May
2011.
5.4.8.
The dredging of the sediment at the
south-western corner of the Causeway Bay Typhoon Shelter was resumed on 26 October
2011,
daily monitoring of suspended solids and 24 hours monitoring of turbidity at
the cooling water intakes at C7 was conducted. With
respect to the seawall collapsing at TS4 on 17 November 2011, the 24 hours turbidity
monitoring and daily SS was kept in November and December 2011. As there was no adverse impact on the SS results
obtained during the period of seawall collapse, the daily SS monitoring at C7
was then suspended on 23 December 2011. The 24hr turbidity monitoring will be
kept to monitor until the completion of reinstating the seawall at TS4.
5.4.9.
Water monitoring results measured in this reporting
period are reviewed and summarized. Details of water quality monitoring results and
graphical presentation can be referred in Appendix

coastal area closed to the cooling intakes C8 and C9, it causes the potential
for accumulation of pollutants near the intakes and may lead to potential water
quality deterioration at the seawater intake points. Investigation revealed
that the SS exceedance at WSD15 was located in upstream of the Project during flood
tide and the water quality at monitoring stations located nearest the marine
work site were well below the Action level.

From the Monthly EM&A report (November 2011) of Central Reclamation
Phase III the key works in December 2011 are as follows:
·
Type A filling in FRAW and FRAE above +2.5mPD
·
General filling works above +2.5mPD in IRAE
·
Surcharging in FRAW and FRAE
·
Construction of GPO boundary wall

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 activities at Reclamation Shoreline Sub-zones
under Wan Chai Development Phase II were the reclamation works at NPR2E,
dredging and filling at HKCEC3w, dredging at submarine sewage pipelines, reinstatement
of seawall block construction at TCBR1W and marine bored piling at MTR Tunnel
Crossing in the reporting month. The major environmental impact was water
quality impact at North Point, Causeway Bay and Wan Chai.
7.0.4.
The major environmental impacts generated from the
filling work at Central Reclamation Phase III were only located along the
coastline of Central and Admiralty. As no project related exceedance was
recorded in the Project, it was considered no adverse environmental impact
caused by the Project works. Thus, it is evaluated the cumulative construction
impact from the concurrent projects including Wan Chai Development Phase II and
Central Reclamation Phase III was insignificant.
