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.

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 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

4.2.7.
A clean laboratory with constant temperature and humidity control, and
equipped with necessary measuring and conditioning instruments to handle the
dust samples collected, shall be available for sample analysis, and equipment
calibration and maintenance. The laboratory should be HOKLAS accredited.
4.2.8.
An alternative non-HOKLAS accredited
laboratory was set-up for carrying out the laboratory analysis,
the laboratory equipment was approved by the ER on
8 February 2011 and
the measurement procedures were witnessed by the IEC. Any measurement
performed by the laboratory was be demonstrated to the satisfaction of
the ER and IEC. IEC shall regularly audit to the measurement performed by the
laboratory to ensure the accuracy of measurement results.
4.2.9.
Filter paper of size 8” x 10” shall be labelled before sampling. It
shall be a clean filter paper with no pinholes, and shall be conditioned in a
humidity-controlled chamber for over 24-hours and be pre-weighed before use for
the sampling.
4.2.10.
After sampling, the filter paper loaded with dust shall be kept in a
clean and tightly sealed plastic bag. The filter paper shall then be returned
to the laboratory for reconditioning in the humidity controlled chamber
followed by accurate weighing by an electronic balance with readout down to 0.1
mg. The balance shall be regularly calibrated against a traceable standard.
4.2.11.
All the collected samples shall be kept in a good condition for 6 months
before disposal.
impact monitoring for
odour patrol
4.2.12.
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
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 4.1.
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 1 WSD salt water intakes
and 7 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.

was observed from a hopper barge moored near shore and other construction
plants under operation from the reclamation construction site with Contract no.
HK/2009/02 at location outside Wan Chai Sports Ground caused air pollution. The
complainant alleged that the said situation had been observed for a prolonged
period.
ET confirmed with the Resident Site
Staff that reinforced bar fixing and concreting work (on 17 June 2015 only)

operation. In addition, on 15 June 2015, 17 June 2015 and 19 June 2015, 1 no.
of derrick barge was moored near Portions 3 & 4 for transportation of the
excavated material away from site.
According to the relevant site records
under Contract HK/2009/02, from 15 June 2015 to 19 June 2015, reinforced bar
fixing and concreting work (on 17 June 2015 only) were conducted at Portion 2
