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 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.

2.3.1. 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 (FEP) 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
4.1.5. 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.
4.1.6. 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.
4.1.7. 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
4.1.8. 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.
4.1.9. 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

Air Monitoring Parameters,
Frequency and Duration
4.2.2. One-hour
and 24-hour TSP levels should be measured to indicate the impacts of
construction dust on air quality. The 24-hour TSP levels shall be measured by
following the standard high volume sampling method as set out in the Title 40
of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B.
4.2.3. All
relevant data including temperature, pressure, weather conditions, elapsed-time
meter reading for the start and stop of the sampler, identification and weight
of the filter paper, and any other local atmospheric factors affecting or
affected by site conditions, etc., shall be recorded down in detail.
4.2.4. For
regular impact monitoring, the sampling frequency of at least once in every
six-days, shall be strictly observed at all the monitoring stations for 24-hour
TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least
three times in every six-days should be undertaken when the highest dust impact
occurs.
Sampling Procedure and
Monitoring Equipment
4.2.5. High
volume samplers (HVSs) in compliance with the following specifications shall be
used for carrying out the 1-hour and 24-hour TSP monitoring:
·
0.6
– 1.7 m3 per minute adjustable flow range;
·
equipped
with a timing / control device with +/- 5 minutes accuracy for 24 hours
operation;
·
installed
with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;
·

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.
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.
Water Quality Monitoring Stations
4.3.3. It is
proposed to monitor the water quality at 3 WSD salt water intakes and 8 cooling
water intakes along the seafront of the Victoria Harbour. The proposed water quality
monitoring stations of the Project are shown in Table 4.4 and Figure 4.1. Appendix 4.1
shows the established Action/Limit Levels for the monitoring works.

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 were marine works at HKCEC areas, tunnel works at Wan Chai
East and filling works at Wan Chai West. The major construction activities
under Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were bridge
construction and tunnel works at Central Interchange, land base bored pilling
works at Victoria Park Road and ELS, segment launching works and tunnel works
at North Point area. The major environmental impact was water quality impact at
Causeway Bay and Wan Chai. Marine-based construction activities were filling
works at WanChai West and removal of temporary reclamation at TS4, TS2 and
EX-PCWA at Wan Chai East in the reporting month.
7.0.5.
No significant air impact from construction
activities was anticipated in the reporting month. Besides, project related exceedances
were recorded during the air and noise environmental monitoring events in the
