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.

Harbour Road Sports Centre were finely adjusted on 16 and 25 May 2017 and
thereafter to the Footbridge for Harbour Road Sports for noise monitoring
Noise Monitoring Parameters, Frequency and Duration
4.1.2.
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.
4.1.3.
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.
4.1.4.
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.
Monitoring Equipment
4.1.5.
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.
4.1.6.
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 4.2
and Figure 4.1. Appendix 4.1 shows the established
Action/Limit Levels for the monitoring works.

Boundary Wall” from 05 June 2017 onwards.
Remarks***: The
station ID and monitoring location was updated in December 2014 with respect to
monitoring station relocation.
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;

4.2.6.
Initial
calibration of dust monitoring equipment shall be conducted upon installation
and thereafter at bi-monthly intervals. The transfer standard shall be
traceable to the internationally recognized primary standard and be calibrated
annually. The concern parties such as IEC shall properly document the
calibration data for future reference. All the data should be converted into
standard temperature and pressure condition.
Laboratory Measurement / Analysis
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.
Water
quality monitoring was undertaken at 8 monitoring stations for WSD salt water
intakes and cooling water intakes along the seafront of the Victoria Harbour in
the reporting month. The proposed water quality monitoring stations of the
Project are shown in Table 4.3 and Figure 4.1. Appendix
4.1 shows the established Action/Limit Levels for the monitoring
works.
