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 Designated 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.
Design and Construction of Central – Wan Chai
Bypass and Island Eastern Corridor Link under the Project involves the
construction and operation of a trunk road and its road tunnel more than 800m
in length between portals that is shown at Figure 2.1.
2.2.2.
The study area encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:
·
A dual
three-lane trunk road, approximately 4.5 km in length, and tunnel approximately
3.7 km in length defined from the connection with the existing Rumsey Street
Flyover in Central, through to a connection with the existing Island Eastern
Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);
·
The
Central Interchange near the Rumsey Street Flyover to provide road connections
to the Central area;
·
Tunnel
control buildings and ventilation buildings;
·
Slip
roads to connect the CWB to the local road system in the Wan Chai North and
Causeway Bay area;
·
Associated
road lighting, road signing, traffic control and surveillance system; and
·
Other
associated works.
2.2.3.
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.

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 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.

5.3.2
As
demolition of concrete slab work will be conducted at CMA1b - Harbour Grand
Hotel Boundary Wall and there is no other appropriate locations for
installation of sampler, air quality monitoring station CMA1b - Harbour Grand
Hotel Boundary Wall will be suspended and represented by CMA2a-Causeway Bay
Community Centre from 12 March 2021 onward due to short separation distance
between two stations.
5.3.3
One action level exceedances of 24hr TSP were
recorded at CMA 2a on 17 April 2021 in the reporting period.
5.3.4
After the investigation, it was noted that
removal of launching girder parts was undertaken on the monitoring date at
around monitoring station CMA2a under Contractor of HY/2009/19 and no
particular observation regarding air quality impact was observed during
sampling. Meanwhile, elevated PM2.5 (Range from 8.5μg/m3 to 47.5μg/m3) and PM10
(Ranged from 16.1μg/m3 to 68.6μg/m3) level was recorded at EPD's
Central/Western, Eastern General Station, Central Roadside Station and Causeway
Bay Roadside Station. In addition, similar elevation in TSP level were recorded
across the same period on 17 April 2021 at another AQM station at Central area
(MA1b:201.1μg/m3), while no construction work was carried out around. In view
of the above, the action level exceedance was considered to be non-project
related and contributed by local ambient condition. No exceedance was recorded
in the subsequent 1hr TSP monitoring on 19 April 2021. Nevertheless, the
Contractor of HY/2009/19 was reminded to maintain regularly dust suppression
measures for any potential dusty surface and dust generating operation around
the concerned location to avoid any potential cumulative air quality impact.
5.3.5
One action level exceedances of 24hr TSP were
recorded at MA1b on 17 April 2021 in the reporting period.
5.3.6
After the investigation, it was noted that no
construction works was undertaken on the monitoring date at around monitoring
station MA1b under Contractor of HY/2009/19 and no particular observation
regarding air quality impact was observed during sampling. Meanwhile, elevated PM2.5
(Range from 8.5μg/m3 to 47.5μg/m3) and PM10 (Ranged from 16.1μg/m3 to
68.6μg/m3) level was recorded at EPD's Central/Western, Eastern General
Station, Central Roadside Station and Causeway Bay Roadside Station. In view of the above, the action level
exceedance was considered to be non-project related and contributed by local
ambient condition. No exceedance was recorded in the subsequent 1hr TSP
monitoring on 19 April 2021.
