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:
¡P 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
¡P
Reprovisioning /
protection of the existing facilities and structures affected by the land
formation works mentioned above
¡P
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
¡P
Upgrading of
hinterland storm water drainage system and sewerage system, which would be
rendered insufficient by the land formation works mentioned above
¡P
Provision of the
ground level roads, flyovers, footbridges, necessary transport facilities and
the associated utility services
¡P
Construction of
the new waterfront promenade, landscape works and the associated utility
services
¡P
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
4.1.3.
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:
¡P
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 ¡V 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 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:
¡P
0.6 - 1.7 m3 per
minute adjustable flow range;
¡P
equipped with a
timing / control device with +/- 5 minutes accuracy for 24 hours operation;
¡P
installed with
elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;
¡P
capable of
providing a minimum exposed area of 406 cm2;
¡P
flow control
accuracy: +/- 2.5% deviation over 24-hour sampling period;
¡P
equipped with a

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
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.
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.
Water Quality Monitoring Stations
4.3.2.
It is proposed to monitor the water quality at 9
WSD salt water intakes and 12 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.

Water Quality Parameters
4.3.3.
Monitoring of dissolved oxygen (DO), turbidity and
suspended solids (SS) shall be carried out at WSD flushing water intakes and
cooling water intakes. DO and Turbidity are measured in-situ while SS is
determined in laboratory.
4.3.4.
In association with the water quality parameters,
other relevant data shall also be measured, such as monitoring
location/position, time, sampling depth, water temperature, pH, salinity,
dissolved oxygen (DO) saturation, weather conditions, sea conditions, tidal
stage, and any special phenomena and work underway at the construction site
etc.
Sampling Procedures and Monitoring Equipment
4.3.5.
The interval between two sets of monitoring should
not be less than 36 hours except where there are exceedances of Action and/or
Limit Levels, in which case the monitoring frequency will be increased. Table 4.5 shows the
proposed monitoring frequency and water quality parameters. Duplicate in-situ measurements and water
sampling should be carried out in each sampling event. For selection of tides for in-situ
measurement and water sampling, tidal range of individual flood and ebb tides should
be not less than 0.5m.

The
maintenance works and testing of flush water pump system at Windsor House intake
(C7) have been carried out in the reporting month. The
silt screen at C7 was then removed on 15 February 2011 and then reinstated on
29 March 2011 to facilitate their maintenance works as per the intake owner¡¦s
request. Considering the absence of intake pump operation at Windsor
House intake (C7), this sensitive receiver was apparently not exist
during this period so
that no water quality monitoring at C7 for compliance checking was undertaken
in this reporting month.
5.4.9.
Water
quality monitoring at station C3 was not available to proceed on 18 March 2011
during ebb tide. The contractor was notified and rectifications were undertaken
immediately on the same day, consecutive monitoring at flood tide was conducted

Referring to the
exceedances shown in Table 5.9, the occasionally action and limit
level exceedances of turbidity and suspended solid were recorded at C8 and C9.
Stations Since there were numerous unknown outfalls from the nearby 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. The recorded turbidity and
SS exceedances were concluded as not project related.

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 under Wan Chai Development Phase II
were the dredging and filling works at North Point Reclamation Shoreline
Subzone (NPR2E) and (NPR1& NPR2W) respectively, the filling at Wan Chai
Reclamation Shoreline Subzone (Submarine sewage pipeline) respectively,
dredging at HKCEC3W and dredging at TCBR and filling at TPCEAE in the reporting
month. The major environmental impact was water quality impact at North Point
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, it is evaluated the cumulative construction impact from the
concurrent projects including Wan Chai Development Phase II and Central
Reclamation Phase III was insignificant.
8.0.1.
During this reporting month, weekly environmental
site audits were conducted for Contracts no. HY/2009/11, HK/2009/01, HK/2009/02
and HY/2009/15. No non-conformance was identified during the site audits.
