“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.

Public 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
4.2.13. Odour
patrol shall be conducted by independent trained personnel / competent persons
patrolling and sniffing around the shore as shown in Figure 4.1 to detect any odour at
the concerned hours (afternoon is preferred for higher daily temperature).
4.2.14. 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.
4.2.15. 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.
4.2.16.
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 6.1.
4.2.17.
The qualified odour patrol member has individual
n-butanol thresholds complied with the requirement of European Standard Method
of Air Quality – Determination of Odour Concentration by Dynamic Olfactometry
(EN13725) in the range of 20 to 80 ppb. The certificate for the qualified odour
panel member is shown in Appendix 4.2.
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.
4.3.2.
The updated EM&A Manual for EP-356/2009
(Version in March 2011) is approval by EPD on 29 April 2011. As such, the
