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.
2.3.2.
In the
reporting month, the dredging works for Contracts no. HK/2009/01 and
HK/2009/02 were commenced on 23 July and 5 July 2010 respectively. The details of individual

4.1.1.Reviewed the past
monitoring results and observation at Station M4a, the monitoring location at
Causeway Bay Community Centre is facing and closed to the Island Eastern
Corridor. Traffic noise is the major noise source obtained in the monitoring
that cannot be reflected the
fact of the construction noise from the construction site.
Victoria Centre (Station ID: M4b) is proposed as alternative noise monitoring station,
which is more appropriate and
representative as noise monitoring station for monitoring the construction
noise arising from the near construction site.
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.
4.1.8. The sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency before deployment to the site and during each site visit. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.
Air Quality Monitoring Stations
4.2.1.
The air monitoring stations for the
Project are listed and shown in Table 4.2 3 and Figure 4.1.

Action/Limit Levels for the monitoring works.

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;
·
capable of providing a minimum exposed area
of 406 cm2;
·
flow control accuracy: +/- 2.5% deviation
over 24-hour sampling period;
·
equipped with a shelter to protect the filter
and sampler;
·
incorporated with an electronic mass flow
rate controller or other equivalent devices;
·
equipped with a flow recorder for continuous
monitoring;
·
provided with a peaked roof inlet;
·
incorporated with a manometer;
·
able to hold and seal the filter paper to the
sampler housing at horizontal position;
·
easily changeable filter; and
·
capable of operating continuously for a
24-hour period.
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. Filter paper of size 8" x 10" shall be labeled 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.
4.2.9. 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.
4.2.10. 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 4.3 4 and Figure 4.1. Appendix 4.1 shows the established
Action/Limit Levels for the monitoring works.

The
major environmental impacts generated from the Central Reclamation Phase III were located along the coastline
of Central and Admiralty while
dredging works at NPR1, WCR1 and
Cross-harbour water Mains
were in operation in this reporting month.
Since no Project-related
exceedance was recorded from the Project in the reporting month, it
is evaluated that the
cumulative construction impact from the
concurrent projects including Wan Chai Development Phase II and Central Reclamation Phase III was insignificant.According to the construction programme of Central-Wan Chai Baypass and Island Eastern Corridor
Link projects, the
major construction activity under Wan Chai
Development Phase II was the dredging works at
North Point Reclamation Stage 1(NPR1), Wan Chai Reclamation Stage 1(WCR1)
