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
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
2.2.1.
The
Project is located mainly in Wan Chai North,
2.2.2.
The
study area encompasses existing developments along the Wan Chai,
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.

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.

Noise Monitoring
Parameters, Frequency and Duration
3.1.2.
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.
3.1.3.
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.
3.1.4.
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.
3.1.5.
Real
time noise shall be carried out at the designated monitoring stations. The
following is an initial guide on the regular monitoring frequency for each
station on a 24 hours daily basis when noise generating activities are
underway:
 -
One
set of measurements between 0700 and 1900 hours on normal weekdays.
 -
One
set of measurements between 1900 and 2300 hours on normal weekdays and 0700 and
2300 hours on public holidays.
 -
One
set of measurements between 2300 and 0700 hours on next day on everyday.
3.1.6.
Noise
baseline level review was commenced in this reporting period. Detailed review
report showed in
Appendix 3.2.
3.1.7.
Real
time noise baseline level review at night time period (2300 to 0700) was
commenced in this reporting period. Detailed review report showed in
Appendix 3.3.
Monitoring Equipment
3.1.8.
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.
3.1.9.
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.

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
3.2.13 Odour patrol shall be conducted by
independent trained personnel / competent persons patrolling and sniffing
around the shore as shown in

3.2.14 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.
3.2.15 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.
3.2.16 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 3.1.
3.3.1.
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.
3.3.2.
The updated EM&A Manual for EP-356/2009
(Version in March 2011) is approval by EPD on 29 April 2011. As such, the

7.0.1.
According to Condition 3.4 of the EP-356/2009, this
section addresses the relevant cumulative construction impact due to the
concurrent activities of the current projects including the Central Reclamation
Phase III, Central-Wanchai Bypass and Island Eastern Corridor Link projects.
7.0.2.
According to the Monthly EM&A report (April
2012) of Central Reclamation Phase III (CRIII),filling works, building
construction works and pipe works were performed in the April 2012 reporting
month. The water quality monitoring was completed in October 2011 and no exceedance
was recorded for air and noise monitoring. It can be concluded that cumulative construction
impact due to the concurrent activities of the current projects with the
Central Reclamation Phase III (CRIII) was insignificant.
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 at Reclamation Shoreline Sub-zones
under Wan Chai Development Phase II were the dredging and filling at HKCEC3w,
dredging at submarine sewage pipelines, reinstatement of seawall block
construction at TCBR1W and marine bored piling at MTR Tunnel Crossing in the
reporting month. The major environmental impact was water quality impact at
North Point,
7.0.4.
The major environmental impacts generated from the reclamation
work at Central Reclamation Phase III were only located along the coastline of
Central and Admiralty. As no project related exceedance was recorded in the
Project, it was considered no adverse environmental impact caused by the
Project works. Thus, it is evaluated the cumulative construction impact was
insignificant.
8.0.1.
The
EM&A programme was carried out in accordance with the EM&A Manual
requirements, minor alterations to the programme proposed were made in response
to changing circumstances.
8.0.2.
No
non-compliances were noted and no prosecutions were received during the
reporting period.
8.0.3.
The
construction programmes of individual contracts are provided in
Appendix 7.1.
