(Station ID: M4b) is proposed as alternative noise monitoring station from
August 2010.
Noise monitoring during daytime was
conducted at the M1a –
Harbour Road Sports Centre in this reporting month. Due to
the marine works undertaken in evening time from 12 July 2010, noise monitoring
during evening time was conducted from 13 July 2010. Three
limit level exceedances were recorded at 3, 10 and 17 during
restricted hourin reporting month. It is
concluded as not related to the Project works. However, baseline noise level at
M1 needs to be reviewed in next reporting month.Investigation found that
is not project related exceedances.

Exceedance at C8 on 16 December 2010 was recorded. Due to intake owner's constraint, delay was experienced in the
re-provision of modified frame-type silt screen to protect City Garden intake
against potential impact arising from the dredging works and accumulation of
pollutants from nearby outfall adjacent to the intake. The exceedances were
confirmed related to HY/2009/11 contractor difficulties in the provision of
frame type silt screen. Contractor
was reminded to enhance mitigation measures with a double layer silt curtain
and to reduce dredging rate before the frame type silt screen could be installed. Close monitoring on contractor mitigation
and the variation of water quality results will be maintained. Contractor will
further liaise with the owner on the
re-provision of the frame-type silt screen.

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.
.
4.1.1.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.
The sound level meter shall be checked using an
acoustic calibrator generating a known sound pressure level at a known

was Since
was fthere 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. Most of the turbidity and SS exceedances were concluded as natural variation and not
projected
related exceedances excluded the
exceedance at C8 on 16
December 2010.
6.4.3.
Exceedance in SS and turbidity at C8 was recorded on 16 December 2010. The dredging rate at sub-zone NPR2E was 1,500m3,
which is complied with the FEP condition. Due to intake owner's constraint, delay was experienced in
the re-provision of modified frame type silt screen to protect City Garden
intake against potential impact arising from the dredging works and
accumulation of pollutants from nearby outfall adjacent to the intake. The exceedances were
confirmed related to HY/2009/11 contractor difficulties in the provision of
frame-type silt screen.
6.4.4.
A site investigation was conducted with RE and
contractor on 22 December 2010. Contractor was reminded to enhance mitigation
measures with a double layer silt curtain and to reduce dredging rate
before the frame-type silt screen could be
installed. Close monitoring on contractor
mitigation and the variation of water quality results will be maintained. Contractor will further liase with the
owner on the
re-provision of the
frame-type silt screen.

Investigation for the SS and dissolved
oxygen exceedances recorded at relevant monitoring found that the
condition of silt screen and silt curtain are was in proper
condition and low daily
dredging rate (270m3) are were complied with
EP condition.,
Besides, the additional
measure of additional silt curtain is deployed to protect the monitoring stations WSD21. Thus, tthe he exceedances
were
was considered
due toas
natural variation and not related to the Project.

on 3 December 2010 was regarding to the bad odour generated from the dredging
plant off North Point. The noise nuisance and visual impact was complained on 6
December 2010 that was arisen from the 2 barges and spot light pointing
directly to the complainant flat. No Two noise complaints was were received
dated 31 July 2010
and 12 August 2010. The complaint dated 31 July 2010 was
regarding the noise nuisance generated
from dredging work adjacent
to Oil Street and three construction plantin the
reporting month. In the last reporting month, the complaint log no. 100615 recorded on 15 June
2010 was
subsequently considered as an enquiry. RSS clarified that the
above issue was logged as an enquiry rather than a complaint in Highway
Department’s record. s were operated
concurrently. Noise monitoring results
at stations M4b and M5b during the daytime and evening time were
reviewed and no exceedanced was recorded on 27 July and 3 August 2010. The PME used in the dredging works were checked and
confirmed compliance with the EP and
valid CNP no.
