“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.

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.
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

There were occasionally DO exceedances recorded at C1,
C3, C4e and C4w in this reporting month. No odour nuisance was noted during DO monitoring.
Confirmed with Contractor, there was no work conducted during the water quality
monitoring. The exceedances were possible in relation to the natural variation
or changes of water quality in the vicinity of the water quality monitoring
station and not project related.
6.4.3
Turbidity and SS exceedances at WSD19 were
occasionally recorded in this reporting month. In view that the water quality
at monitoring stations located nearest the marine work site were well below
Action Level and the silt screen was in proper condition, the exceedances were
possible in relation to the changes of
water quality in the vicinity of the water quality monitoring station and not
project related.
6.4.4
SS exceedance at C2 was recorded on 25 October
2012. According to the information reported by Contractor HK/2010/06 and
HK/2009/01 on 25 Oct 2012, pile head breaking under HK/2010/06 and filling at
HKCEC water channel under HK/2009/01 were conducted on that day. In view that
the water quality at monitoring stations located nearest the marine work site
were well below Action Level and the silt screen was in proper condition, the
exceedance was possible in relation to the natural variation or changes of
water quality in the vicinity of the water quality monitoring station and not
project related.

6.4.5
There were turbidity and SS exceedances recorded at
C5w on 8 Oct 2012 during ebb tide. Checking with Contractor’s work, no marine
work was conducted on that day. Checking with contractor's inspection record,
the silt screen was in proper condition on that day. The exceedance was
considered as trapping of unknown particles inside the silt screen. The
contractor was reminded water quality near to the intake should be provided
with sufficient protection. The exceedance was considered not project related.
6.4.6
There were turbidity and SS exceedances recorded at
C5e and C5w on 13 and 15 Oct 2012 during ebb tide. Muddy water quality
appearance inside and outside silt screen were observed during monitoring. Checking
with Contractor’s work, rockfilling near temporary seawall at WCR2 was
conducted on that day. Checking with contractor's inspection record, the silt
screen and silt curtain for rockfilling were in proper condition on that day. Although
the Contractor's records have shown a well maintained silt curtain and silt
screen, muddy water was still observed around the intake during
monitoring. The turbidity and SS
concentration has returned to below the Action Level after stopping of filling
works during the flood tide. This
shows possible defects at the silt curtain and that protection around the
intake is inadequate to protect the sensitive receiver during the filling
activities.
6.4.7
There were turbidity exceedances recorded at C5e
and C5w on 17 Oct 2012 during flood tide. Checking with Contractor’s work,
rockfilling in WCR2 was conducted on that day. Checking with contractor's
inspection record, the silt screen and silt curtain for rockfilling were in
proper condition on that day. The exceedance was considered as natural
variation or changes of water quality in the vicinity of the water quality
monitoring station and not project related.
6.4.8
There were turbidity and SS exceedances recorded at
C5w on 20 October 2012 during flood tide. Silty water was observed discharging
from water pipe into Well B during monitoring. 21.65 NTU turbidity was recorded outside the silt
screen. Contractor immediately removed the pipe from Well B. ET reminded
Contractor should ensure the water pumping into Well for cooling purpose should
not deteriorate the water quality of intake. No further exceedance was recorded
in the next consecutive water monitoring on 22 Oct. The turbidity and SS
concentration has returned to below the Action Level after removal of water
pipe.
6.4.9
There were turbidity and SS exceedances recorded at
C5e on 25 October 2012 during flood tide. Muddy dispersion into the Well as a
result of the rockfilling in WCR2 was observed during inspection walk on 25
Oct. ET recommended that gaps at temporary sheet pile at Well B should be
sealed up and the turbid water inside well should be treated to improve the
water quality in the well. Daily water quality monitoring at C5e was conducted
on 26 Oct 12 under Event and Action Plan. The turbidity of C5e was 7.38 NTU on
26 Oct 12 which is below Action level. The turbidity and SS concentration has
returned to below the Action Level after the improvement of condition of
temporary sheet pile at Well.
6.4.10 There were
occasionally DO, turbidity and SS exceedances recorded at WSD21 in this
reporting month. Checking with Contractor’s work, rockfilling in WCR2 was
conducted on those days. Checking with contractor's inspection record, the silt
screen and silt curtain for rockfilling were in proper condition on that day.
The exceedance was considered as natural variation or changes of water quality
in the vicinity of the water quality monitoring station and not project
related.
6.4.11 There was
SS exceedance at mid-flood recorded at WSD21 on 15 October 2012. Confirmed with
Contractor, Checking with Contractor’s work, rockfilling in WCR2 was conducted
on those days. Checking with contractor's inspection record, the silt screen
and silt curtain for rockfilling were in proper condition on that day. The
exceedance was possibly due to cleaning of screen panels at WSD intake.
Materials from the cleaning of screen panels were unavoidably collected during
monitoring. The exceedance was considered as not project related.
6.4.12 There were
DO exceedances recorded at WSD21 on 4, 6 and 10 October 2012 in this reporting
month. No odour nuisance was noted during DO monitoring. Confirmed with
Contractor, there was no work conducted during the water quality monitoring.

in the vicinity of the water quality monitoring station and not project
related.
6.4.13 There were
occasionally turbidity and SS exceedances recorded at WSD17 and WSD9 in this
reporting month. In view that the water quality at monitoring stations located
nearest the marine work site were well below Action Level and the silt screen
was in proper condition, the exceedance was possible in relation to the natural
variation or changes of water quality in the vicinity of the water quality
monitoring station and not project related.
6.4.14 There were
turbidity and SS exceedances recorded at WSD17 on 28 September 2012 and 2
October 2012. Checking with contractor’s record, cleaning screen panel at
Quarry Bay WSD intake was conducted on these days. The exceedances were

Central- Wan Chai Bypass Tunnel (North Point Section) and Island Eastern
Corridor Link
6.4.18 There were
occasionally turbidity and SS exceedances at C8 and C9 recorded in this
reporting month. Confirmed with Contractor, there was no marine work conducted
near C8 and C9.The exceedances were possible in relation to the accumulation of
particles discharged from outfalls near monitoring stations and not related to

6.4.19 Summary
for notification of exceedances can be referred to Appendix 6.2.
6.5.1
There was no non-compliance from the site audits in
the reporting month. The observations and recommendations made in each individual
site audit session were presented in Section 8.
6.6.1
There was no particular action taken since no
project-related non-compliance was recorded from the site audits and environmental
monitoring in the reporting month.
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 (September
2012) of Central Reclamation Phase III (CRIII), filling works, building construction
works and pipe works were performed in the October 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,
Causeway Bay and Wan Chai.
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 while the adverse water impact was only located in the WCR2
in relation to the rock filling operation causing exceedances in WCR2 in this
reporting month. Thus, it was unlikely to have cumulative impact from CRIII. It
is evaluated the cumulative construction impact from the concurrent projects
including Wan Chai Development Phase II and Central Reclamation Phase III was
insignificant.
8.0.1.
During this reporting month, weekly environmental
site audits were conducted for Contracts no. HK/2009/01, HK/2009/02, HY/2009/15,
HK/2010/06 and HY/2009/19. No non-conformance was identified during the site
audits.
8.0.2.

quality monitoring at C8 and C9 have been implemented with respect to
HY/2009/19 since the marine bore
piling work started on 28 January 2012.
10.0.6.
Based
on the safety concern when external façade refurbishment was conducted by
contractor employed by Provident Centre (C9) between 9 January 2012 to 30 July
2012 which caused to the inaccessibility of sampling either land and marine
since 3 Feb 2012, there is a fine adjustment of the sampling location of water
quality monitoring at C9 since 10 March 2012 to the closest accessible point
prior to the completion of the external façade refurbishment work.
10.0.7.
Due
to the access of water monitoring station at WSD19 was blocked by LCSD
construction works from 3 April 2012 to 2 May 2012 and lead to the
inaccessibility of sampling either land and marine, there is a fine adjustment
of the sampling point of WSD 19 since 5 April 2012 to the closest accessible
point prior to the completion of the construction activities.
10.0.8.
With respect to the trial
dredging at WCR2 was scheduled on 20, 22, 24, 25 March and 1, 3, 11, 13, 15, 17, 19, 20 Apr
and 3 May 2012, on-going water quality monitoring
results at WSD21 during this period was checked and indicated that there was no
contribution due to the trial dredging operation. Enhanced review of
water quality around WCR2 was also implemented and no deterioration in the
water quality was observed.
10.0.9. Due to the dredging works for Cross Harbour Water Mains from
Wan Chai to Tsim Sha Tsui- DP6 was completed on 26 March 2012, the temporary
suspension of impact water quality monitoring at WSD7 and WSD20 after 27 April
2012 for the water quality monitoring at WSD7 and WSD20 have been monitored for
4-week period after the completion of DP6 to confirm no water deterioration.
