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. 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
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.
Monitoring Equipment
3.1.6. 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.
3.1.7. 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 Quality Monitoring

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 Figure 3.1 to detect any odour at
the concerned hours (afternoon is preferred for higher daily temperature).
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
