·
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.

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.

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
Action Level and Limit Level for the wet season (April – September) will be
effected and applied to the water quality monitoring data from 30 April 2011.

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 (August 2012) of Central
Reclamation Phase III (CRIII), filling works, building construction works and
pipe works were performed in the September 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,
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.
