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.

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.

confirm no water deterioration.
5.4.10. During the weekly site inspection for
HY/2009/15 on 10 July 2012 and further inspection on 11 July 2012, it was found
that the seawall blocks on the south side of TCBR1E (TS1) have been removed
before all dredging works have been completed. The contractor has immediately
surrounded the seawall gap with silt curtains and stopped the relevant dredging
works on 12 July 2012. No action or
limit level exceedance was found during the water quality monitoring on 9 or 11
July 2012. The contractor has
promised to provide double layer silt curtains and geotextile to act as
temporary seawall and covered the sloping seawall with geotextile, and would
provide a full incident report. A
self water quality monitoring was conducted on 15 July 2012 to indicate the
effectiveness of the double silt curtain layers and would perform each time
during dredging operations. The
results from the self water quality monitoring showed that the suspended
solids, turbidity and dissolved oxygen level outside the double silt curtain
layers were not affected by the dredging activities inside the silt curtain
layers.

month. Confirmed with Contractor, there was no marine work conducted near C8.The
exceedances were possible in relation to the accumulation of particles
discharged from outfalls near monitoring stations and not related to project.
6.4.12 Summary for
notification of exceedances can be referred to Appendix 6.2.
6.5.1.
During the reporting month of August 2012,
contractor of HY/2009/15 has failed to demonstrate compliance with the conditions
set in FEP-04/356/2009 and relevant conditions in EP-356/2009 for the temporary
reclamation removal operations at TCBR1E (TS1). Contractor was unable to provide a proper
method statement with respect to the change in works circumstance, and the
Contractor was unable to effectively mitigate the impact due to non-compliance
such that muddy boom recurrence
occurred and dispersed into
6.5.2.
The observations and recommendations from site
audits made in each individual site audit session were presented in Section 8.
6.6.1.
Warning letters from ETL regarding the situation at
TS1 were issued to the contractor of HY/2009/15 on multiple occasions with
recommended mitigation measures, and the contractor has immediately deployed
silt curtains to conceal the seawall gaps.
6.6.2.
As removal dredging and barge mooring operations
were anticipated to be performed at the southern side of TS1, ETL requested
that daily self water quality tests during removal dredging operations, also
pilot test for mooring operations, to demonstrate the effectiveness of the
mitigation measures during the operation and to demonstrate the operation
itself would not cause substantial water quality impact, should be performed
before the mooring operations.
These tests were requested to prove whether conditions set in
FEP-04/356/2009 and relevant conditions EP-356/2009 are fully complied.
6.6.3.
Water samplings for self water quality tests were
collected at locations inside and outside the silt curtains during removal
dredging operations. This was to
demonstrate whether the double silt curtains could
effectively hold back silty water during removal dredging operations.
6.6.4.
Water samplings for pilot test were collected
inside and outside the double silt curtains before and after the mooring
operations. This was to demonstrate
whether the double silt curtains could effectively hold back silty water during
removal mooring operations, and if high turbid would be generated during the
mooring operations.
6.6.5.
On 15 July 2012, a successful self water quality
test was performed by the contractor.
6.6.6.
Pilot tests were carried out on 27 July, 2, 7 and
20 Aug 2012 to demonstrate the compliance of barge mooring operations with the
conditions set in FEP-04/356/2009 and EP-356/2009, but none of the pilot test
was successful.
6.6.7.
It is concluded that the self water quality tests
proved the effectiveness of the mitigation measures, but the pilot tests were a
failure and the contractor cannot demonstrate their ability to comply with the
conditions set in FEP-04/356/2009 and EP-356/2009.
6.6.8.
ETL then strongly recommended the Contractor to
follow the following points for future activities. First, the Contractor should request for
RSS inspections for confirmation of implementation of mitigation measures
before any commencement of work activities that are governed by the EP. Second, if there is any site mitigation
measure not confirmed by RSS for fulfilling the agreed method statements,
contractor shall not commence any environmentally sensitive construction
activities (e.g. dredging, filling, mooring or any works related to temporary
reclamation) unless such site mitigation measures have been properly reviewed
by both ET and IEC. Third, the
revised site mitigation measures should be reviewed and consented by both ET
and IEC before implementation.
6.6.9.
The Contractor and RSS agreed on the above points
and the Contractor submitted Investigation Report regarding the incident at TS1,
Rectification Plan, Preventive Action Plan and revised Method Statement on 7 September
2012.
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 (July
2012) of Central Reclamation Phase III (CRIII), filling works, building
construction works and pipe works were performed in the July 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.
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.
Four site inspections for Contract no. HK/2009/01

There was one complaint received in this reporting month.
9.0.2.
A water impact complaint was received by ET on 21
August 2012 (ICC Ref. No.: 1-375813738 dated 20 August 2012, forwarded by RSS).
The complaint was reported by Mr. Ho that turbid appearance in water quality
generated from dredging operation at the exit of CBTS and lighthouse from two
barges respectively in construction sites of CBTS on 18 and 19 August 2012 between
3:00 and 10:00pm. The complainant requested a follow-up and reply from relevant
department.
9.0.3.
ET
confirmed with the Resident Site Staff that seawall blocks removal at north of
TS1 and removal of amour rocks at tip of Eastern Breakwater for HY/2009/15 were
conducted during the concerned period on 18 August 2012, and seawall blocks
removal at north of TS1 during the concerned period on 19 August 2012.
9.0.4.
After
reviewing the results of water monitoring at C7 on 17 and 20 August 2012, no
exceedance was recorded and the water quality parameters were all below action
level. Site investigation for HY/2009/15 was conducted on 21 August 2012. The
investigation found that inadequate silt curtain for protecting trimming work
at northern side of TS1, impermeable barrier were observed inadequate to
protect the removed seawall location for trimming and dredging at TS1 and inadequate
silt curtain were observed for protecting trimming work at breakwater at TS1.
Reviewing the photo records of the concerned areas provided by RSS and
investigations by RSS, it was found that the silt curtains around the concerned
areas of northern TS1 and Eastern Breakwater were inadequate, and the silt
curtains provided at both ends of the derrick barge were not fully enclosed. Also, after work, the silt curtains were
not properly maintained to surround the affected work areas, causing silt water
leakage into the
9.0.5.
HyD
made a reply to the complainant on 23 August 2012 by phone. HyD replied that
there would be on-going activities in the north side of TS1 and the end tip of
Eastern Breakwater included filling and rock removal works. HyD explained to
the complainant that the Contractor has deployed silt curtain to safeguard the
water quality in the vicinity, but the silt curtain deployment requires further
improvement. RSS has immediately urged the Contractor to implement mitigation
measures and also stepped up supervision on Contractor’s work. RSS would
continue to work with the Contractor on the effectiveness of the environmental
mitigation measures implemented on site, and the Contractor would take into
account of ET and IEC’s recommendations to enhance the environmental mitigation
measures. No further complaint was
received after the response.

summary of complaints are presented in Appendix 9.1.

advised that the dredging works for submarine pipeline at
10.0.3.
Water
quality monitoring at WSD10 and WSD15 will be temporary suspended while water
quality monitoring at WSD9 and WSD17 were implemented with respect to
HK/2009/02 for the water quality monitoring scheduled on 8 Feb 12 onwards;
10.0.4.
Water
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.
10.0.5.
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.
10.0.6.
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.
10.0.7.
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.
10.0.8. 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.
