“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.

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 (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.
2.3.2.

Noise Monitoring
Parameters, Frequency and Duration
3.1.2.
The construction
noise level shall be measured in terms of the A-weighted equivalent continuous sound
pressure level (Leq). Leq (30 minutes) shall be used as
the monitoring parameter for the time period between 0700
and 1900 hours on normal weekdays. For all other time periods, Leq (5
minutes) shall be employed for comparison with the Noise Control
Ordinance (NCO) criteria.
Supplementary information for data auditing, statistical results such as L10
and L90 shall also be obtained for reference.
3.1.3.
Noise monitoring
shall be carried out at all the designated monitoring stations. The monitoring
frequency shall depend on the scale of the construction activities. The
following is an initial guide
on the regular monitoring frequency for each station on a weekly basis when
noise generating activities are underway:
-
one
set of measurements between 0700 and 1900 hours on normal weekdays.
3.1.4.
If construction works are extended to
include works during the hours of 1900 0700 as well as public holidays and Sundays,
additional weekly impact monitoring shall be carried out during respective
restricted hours periods. Applicable permits under NCO shall be obtained by the
Contractor.
3.1.5.
Real
time noise shall be carried out at the designated monitoring stations. The following
is an initial guide on the regular monitoring frequency for each station on a
24 hours daily basis when noise generating activities are underway:

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
3.2.13 Odour patrol shall be conducted by
independent trained personnel / competent persons patrolling and sniffing
around the shore as shown in
Figure 3.1 to detect any odour at the
concerned hours (afternoon is preferred for higher daily temperature).
3.2.14 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.
3.2.15 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.
3.2.16 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 3.1.
3.3.1.
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.
3.3.2.
The updated EM&A Manual for EP-356/2009
(Version in March 2011) is approval by EPD on 29 April 2011. As such, the

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.
4.4.9.
Due to a series of celebratory activities relating
to the Anniversary of the Establishment of HKSAR to be held at the HKCEC and
security search conducted at work sites of the HKCEC, the water quality
monitoring at C1, C2, C4e and C4w WQM stations in ebb and flood tides were temporary
suspended on 30 June 2012.

Due to the adverse weather condition (e.g. Amber
Rainstorm signal or Strong wind signal No.3 or above) were hoisted on 30 June
2012, 5 and 25 July 2012 and 11 and 17 August 2012 , water quality monitoring
at ebb tide were cancelled.
4.4.11.
Due to the adverse weather condition (e.g. Amber Rainstorm
signal or Strong wind signal No.3 or above) was hoisted on 23 July 2012, water
quality monitoring at flood and ebb tide were cancelled.
4.4.12. Based on the joint inspection on 4
Jan 2012 for the NPR area, the 4-week water quality monitoring at WSD9, WSD10,
WSD15, WSD17, C8, C9 to confirm no water deterioration with respect to NPR was
commenced since 7 Jan 2012 and it was completed on 6 February 2012.
4.4.13. Water quality monitoring at WSD10
and WSD15 was temporary suspended while water quality monitoring at WSD9 and
WSD17 was implemented with respect to HK/2009/02 from 8 Feb 12 onwards;
4.4.14. 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 Jan 12.
4.4.15. Based on the safety concern when
external façade refurbishment was conducted by contractor employed by Provident
Center (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.
4.4.16. 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.
4.4.17. 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.
4.4.18. 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.
4.4.19.
As
per the meeting with the representative of Excelsior Hotel and World Trade
Centre on 17 May 2011, they confirmed that the seawater intake for The
Excelsior was no longer in use and replaced by the connected permanent water
supply from WSD pipelines since 11 January 2011. Thus, the impact water quality
monitoring for the cooling intake - C6 was terminated effective from 26 May
2011.
4.4.20. 24 hours monitoring of turbidity at the cooling water intakes at
C7 was conducted. With respect to the seawall collapsing
at TS4 on 17 November 2011, the 24 hours turbidity monitoring and was kept in
November 2011. Since the reinstating the seawall was completed on 13 January
2012 and no any water deterioration was performed, 24 hour turbidity monitoring
was then suspended on 27 January 2012.
4.4.21.
The
enhanced water quality monitoring at C6, C7, Ex-WPCWA-SW and Ex-WPCWA-SE was
commenced on 13 January 2011. /span>No
project-related exceedances was recorded in the daily SS monitoring and 24 hours
turbidity monitoring.

5.5.1.
There
was non-compliance from the site audits in the reporting month of August 2012 in
Contract HY/2009/15. During environmental site inspections conducted during the
reporting period, minor deficiencies were noted.
5.6.1
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 /span>in EP-356/2009 for the temporary reclamation
removal operations at TCBR1E (TS1). /span>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
5.7.2
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.
5.7.3
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.
5.7.4
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.
5.7.5
On 15 July 2012, a successful self water quality
test was performed by the contractor.
5.7.6
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.
5.7.7
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.
5.7.8
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.
5.7.9
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.
.
6.0.1.
There
was one water impact complaint received in this reporting period.
6.0.2.
The details of cumulative complaint log and summary
of complaints are presented in
Appendix 6.1.
6.0.3.
No notification of summons
or prosecution was received in the reporting period. Cumulative statistic on complaints and successful
prosecutions are summarized in Table 6.1 and Table 6.2 respectively.

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), drainage work, building construction
works and pipe works were performed in the reporting period. 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
