Environmental Monitoring and Audit (EM&A) programme as stipulated in the
EM&A Manual of the approved Environmental Impact Assessment (EIA) Report
for Wan Chai Development phase II and Central-Wan Chai Bypass (Register No.:
AEIAR-125/2008) and in the EM&A Manual of the approved EIA Report for
Central-Wan Chai Bypass and Island Eastern Corridor Link (Register No.
AEIAR-014/2001).

Section 8     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 Designed 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.
The Project is located mainly in Wan Chai North,
Causeway Bay and North Point, and is demarcated by Gloucester Road and Victoria
Park Road to the south, Fenwick Pier Street to the west and Tong Shui Road
Interchange to the east, as shown in Figure 2.1.
2.2.2.
The study area encompasses existing developments
along the Wan Chai, Causeway Bay and North Point shorelines. Major land uses
include the Hong Kong Convention & Exhibition Centre (HKCEC) Extension, the
Wan Chai Ferry Pier, the ex-Wan Chai Public Cargo Working Area (ex-PCWA), the
Royal Hong Kong Yacht Club (RHKYC), the Police Officers' Club, the Causeway Bay
Typhoon Shelter (CBTS) and commercial and residential developments.
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.

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.

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

of the sampler, identification and weight of the filter paper, and any other
local atmospheric factors affecting or affected by site conditions, etc., shall
be recorded down in detail.
3.2.4.
For regular impact monitoring, the sampling
frequency of at least once in every six-days, shall be strictly observed at all
the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring,
the sampling frequency of at least three times in every six-days should be
undertaken when the highest dust impact occurs.
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.

The enhanced water quality monitoring at C6,
C7, Ex-WPCWA-SW and Ex-WPCWA-SE was commenced on 13 January 2011. No exceedance
was recorded in the reporting period.
4.4.6.
During dredging of the sediment at the
south-western corner of the Causeway Bay Typhoon Shelter between 15 February
and 24 February 2011, daily monitoring of
suspended solids and 24 hours monitoring of turbidity at cooling water intakes at C6
was be conducted. No project-related exceedance was recorded.
4.4.7.
As per the advised from the RE on 15 February
2011, the maintenance works and suspension of flush water pump system at Windsor House intake (C7) have been carried out between 15
February and 31 March 2011. The installed silt screen at C7 was then removed on
15 February 2011 to facilitate their maintenance works as per the intake
owner’s request. Considering the absence
of intake pump operation at Windsor House intake (C7), this sensitive receiver was apparently not exist during this period so
that no water quality monitoring at C7 for compliance checking was undertaken
starting from 15 February in this reporting period.
4.4.8.
Due to the access restriction of WSD Salt
Water Pumping Stations owing to security reasons and no dredging activities
confirmed with the Contractor between 3 February and 6 February 2011 (Chinese
Lunar New Year Holiday), the scheduled impact water monitoring on 3 and 4
February 2011 was cancelled.

5.4.2.
Investigations were found that the
most of exceedances are unikely related to the Project works except the SS and
turbidity exceedances at C8 on 16 and 30 December 2010 at mid-flood tide, C6 on
7 February 2011 at mid-flood and mid-ebb tides and turbidity exceedances
recorded at C5e, C5w and WSD21 on 11 February 2011 at mid-flood.
5.4.3.
Exceedance at C8 on 16 and 30 December 2010
was recorded. Due to intake owner's
constraint, delay was experienced in the re-provision of modified frame-type
silt screen to protect City Garden intake against potential impact arising from
the dredging works and accumulation of pollutants from nearby outfall adjacent
to the intake. The exceedances were confirmed related to HY/2009/11 contractor
difficulties in the provision of frame type silt screen. Contractor enhanced mitigation measures with
a double layer silt curtain on 7 January 2011. No further exceedance was
recorded after installation of double layer silt curtain. Close monitoring on
contractor mitigation and the variation of water quality results will be
maintained.
5.4.4.
The turbidity exceedances were recorded at
C5e, C5w and WSD21 on 11 Feb 2011 at mid-flood when the local buckling of
western sheetpile temporary seawall at WCR1 was recorded in the morning of 11
February 2011. These exceedances were confirmed due to the buckling of western
sheetpile temporary seawall. Contractor had immediately installed the
additional silt curtain surround the location of buckling seawall on that day.
5.4.5.
Turbidity and SS exceedances at C6 on 7
February 2011 at mid-flood and mid-ebb tides were recorded. Further
investigation on 9 Feb 2011 revealed the crack on the silt screen at C6. A
crack on silt screen structure leaded to ingress of unscreened polluted water
directly to the intake created by frequent vessel movement on shallow water in
Causeway Bay Typhoon Shelter. The exceedances were confirmed due to the silt
screen defect.
5.5.1.
There was no non-compliance from the site
audits in the reporting period. During environmental site inspections conducted
during the reporting quarter, minor deficiencies were noted. However, the Contractor rectified all
deficiencies after receipt of notification.
5.6.1.
No project-related non-compliance from
monitoring was recorded in the reporting period.
5.7.1.
There was no particular action taken since no project-related
non-compliance was recorded from the site audits and environmental monitoring
in the reporting period.
6.0.1.
There were two environmental complaints were
received on 3 and 6 December 2010 in this reporting period. The complaint
received on 3 December 2010 was regarding to the bad odour generated from the
dredging plant off North Point. The noise nuisance and visual impact was complained
on 6 December 2010 that was arisen from the 2 barges and spot light pointing
directly to the complainant flat.  /span>
6.0.2.
The complainant from City Garden complained
on the bad odour from the dredging plant off North Point on 3 December 2010 at
01:45. Investigation of the backhoe barge at City garden conducted by ET with
RE and Contractor of Contract HY/2009/11 was carried on 8 December 2010. No
irritated odour was noted during the site investigation.
6.0.3.
The noise and visual complaint was complained
on 6 December 2010 by the complainant from the City Garden. It was complained
on two barges generating noise at 22:00 on 6 December 2010 in which the noise
from filling operation was louder than the traffic noise and visual impact
generating due to the spot-light pointing directly to the complainant flat and
suspected the filling operation was part of Wanchai Development Phase II.
Complainant also raised the same complaint to District Councillor, Mr. Hui on 7
Dec 2010 regarding the night time noise and suspected earlier start of work at
06:30. Complaint also requested for
limiting the plant operating hours from 09:00-21:00.
6.0.4.
It was checked and confirmed that the two
derrick barges were in operation at the time of complaint for placing 400
rockfill onto the excavation trench and for levelling the formation level to
receive the pre-cast caisson seawall and flood light on the control mast of
derrick barge have no lighting shields for the prevention of glare of flood
lights causing visual glare to the complainant at night-time. Besides,
construction works was started after 0800hrs on 7 December 2010. It was found
that the occasional noise nuisance might be caused by the hitting or scratching
onto the rock surface during loading down the grab onto the Grade 400 rockfill.
Contractor was advised to minimize the finishing time of placing Grade 400
rockfill at 2100hrs and switch off all unnecessary floodlights apart from the
light for the safety and security purpose.

6.0.7.
Incidents
of split bottom hopper barge named Shun Tat 11 (Licence no. B21623V) were
recorded near Kwai Shek (200-300m distance) under Contract no. HY/2009/15 on 17
December 2010 and at the location near Cross Harbour Water Mains marine work
zone under Contract no. HK/2009/01 on 24 January 2011.
6.0.8.
The
hopper barge under Contract no. HY/2009/15 was trapped by a strong current and
grounded on shallow rock clusters on 17 December 2010. Jettison of marine
sediment (Type 1  Open Sea Disposal (Dedicate Sites) & Type 2  Confined
Marine Disposal) in hopper barge at the scene of incident was needed in order
to avoid capsizing of vessel. Contractor informed this incident to EPD on 18
December 2010.
6.0.9.
The
ballast tank on the port side of the split hopper barge under Contract no.
HK/2009/01was flooded with water on 24 January 2011. It was towed back to the
dredging zone within a short period and immediately opened its hopper to dump
the sediment back to the same dredging trench. It is suspected that the hull on
the port side might be broken causing ingress of seawater into the ballast
tanks. Meanwhile, the barge has been demobilized from the site and currently
anchored at To Kwa Wan Typhoon Shelter. The emergency dumping was notified to
EPD on 24 January 2011 at 10:00a.m. This barge will not be deployed to the site
under HK/2009/01 to dispose the dredged sediment until it has been repaired and
inspected by the competent surveyor. These incidents will be kept in view for
determining further follow up and remedial measures. All Contractors under
EP-356/2009 were reminded to ensure the deployed hopper barge has been
adequately checked by qualified person and ensured in good condition before the
engagement on site.
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,
Central-WanChai Bypass and Island Eastern Corridor Link projects.
7.0.2.
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 under Wan Chai
Development Phase II were the dredging and filling works at North Point
Reclamation Shoreline Subzone (NPR2E) and (NPR1) respectively, the dredging and
filling at submarine sewage pipeline and Wan Chai Reclamation Shoreline Subzone
(Submarine sewage pipeline) respectively, dredging at HKCEC3W and cross harbour
water mains and dredging at TCBR in the reporting period. The major environmental
impact was water quality impact at North Point and Wan Chai.
7.0.3.
The major environmental impacts generated
from the filling work at Central Reclamation Phase III were only located along
the coastline of Central and Admiralty. As the recorded project-related
exceedances in North Point, Causeway Bay Typhoon Shelter and Wan Chai that was
localized interference and far away from the work area
of 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.
The EM&A programme was carried out in
accordance with the EM&A Manual requirements, minor alterations to the
programme proposed were made in response to changing circumstances.
8.0.2.
No non-compliances
were noted and no prosecutions were received during the reporting quarter.
8.0.3.
The construction programmes of individual contracts
are provided in Appendix 8.1.
