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 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
·

Noise Monitoring Parameters, Frequency and Duration
4.1.3.
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.
4.1.4.
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.
4.1.5.

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

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.

One
turbidity at C4w was exceeded the Limit Level and One SS level at C4w was exceeded
the Action Level on 1 November 2011. Checking with Contractor works, there were
filling at HKCEC3W. The frame type silt screen at the intake and silt curtain
along the HKCEC water channel were deployed. Other than that, Contractor's
daily records were checked. It shows silt curtains were deployed during filling
works and both silt curtains were in proper condition in their daily
inspection. No exceedance was recorded in the next consecutive monitoring. Thus,
it was concluded not Project related exceedances.

were one turbidity and one SS level exceedance recorded at WSD21 and two SS
levels exceedances recorded at C5w. Contractor marine work activities and
mitigation measures were checked, deployed silt screen at intake and silt
curtain at western temporary sheet pile were observed in proper condition
during the water quality monitoring. It was concluded that these exceedances
were not related to the Project works. Nevertheless, Contractor was reminded to
minimize the silty water seepage from the seawall blocks at western seawall
which has possible water quality impact to the nearby intakes. Contractor was
reminded to take remedial measures to avoid it. Contractor has already deployed
geotextile on the seawall block in this reporting month. Sealing the seawall
gap is under processing in this month and coming month.

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 filling works at NPR2E, dredging
and filling at HKCEC3w, dredging at submarine sewage pipelines, seawall block
construction and filling at TCBR1W, maintenance dredging of navigation channel
and mooring area, and marine bored piling at MTR Tunnel Crossing in the
reporting month. The major environmental impact was water quality impact at
North Point, Causeway Bay and Wan Chai.
7.0.4.
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 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 from the concurrent projects including Wan Chai Development Phase II and
Central Reclamation Phase III was insignificant.

Two
environmental complaints were received on 4 and 6 November 2011 in the
reporting month.
9.0.3.
A tree near the site of
pipe installation works outside Wan Chai Swimming Pool at Harbour Road is
confirmed that is the Tree no. TA1122 under Contract no. HK/2009/02. Leaves of
a branch of this tree were shrivelled. Another two trees inside the site near
Renaissance Hong Kong Harbour View Hotel at Convention Avenue are the tree nos.
A160 and A161 under Contract no. HK/2009/01. Part of roof ball of these two
trees was covered by the metal plate.
9.0.4.
Independent Tree Specialists
for these two inspected the trees. Contractor HK/2009/01 has taken the measure
as recommend downgrading the soil level around the trunk base. Reinstating of
the ground works will be conducted in mid-December 2011. For the tree no.
TA1122 under Contract no. HK/2009/02, the brown leaves were removed and fenced
the tree with orange net is provided to prevent damage of tree trunk by
construction works. The distance between the tree and the edge of the trench is
kept approximate 2m. Two Contractors were reminded to carry out regular
watering to the trees within their site area.
9.0.5.
A noise complaint was
received by Police Officer and a police officer arrived to Contract HK/2009/01
site at about 6:30 a.m. on 6 November 2011 to inspect noise generated from the
site and stop the existed machines operation. The subcontractor for Diaphragm
wall, SAMBO Korean foreman stopped the engine of the BC cutter immediately. The
police officer recorded the details and HKID number of the foreman and then
left. Due to the different language communication between the police officer
and the Korean foreman, no CNP was checked by the police officer.
9.0.6.
According to the
information reported by Contractor, one BC cutter and a hoist were operated for
inspecting all bentonite pipes were in good condition and all joints were
tightened in good position for Diaphragm Wall construction of Shatin-Central
Link. Due to insufficient communication between Contractor HK/2009/01 and their
Korean Sub-contractor, Korean Sub-contractor had not notified to Contractor of
HK/2009/01 and then started to carry out the inspection of the BC cutter,
hoists and bentonite pipes at 6:00a.m to ensure no damages and all the pipe
joints in good position.
9.0.7.
As such, the Contractor HK/2009/01
was reminded to enhance the communication between Contractor and sub-contractor,
and construction Noise Permit should be checked and in place for the
construction works during restricted hour, plus providing environmental
training to all foreman and operators on restricted hour operation.
9.0.8.
The complaint was considered
in relation to the construction works during restricted hours without valid
Construction Noise Permit. No more construction works were conducted during
night time period. The construction works will be conducted in accordance with
the time period stated in valid CNP. This complaint will be kept in view of any
follow-up action from the relevant government activities.

9.0.11. There was
an incident of the leakage of Type III sediment Geosynthetic Container under Contract
HK/2009/01 on 28 October 2011. 3 nos. of Type III geosynthetic container
containing the Type III sediment dredged from Tsim Sha Tsui side of cross
harbour watermains near the Avenue of Starts and Wan Chai Hong Kong Convention
and Exhibition Centre (HKCEC) water channel were executed and disposed to East
Sha Chau Contaminated Mud Disposal Site – Pit IVc. The preplaced PVC spheres
were observed to be floating near the stern of the hopper barge after the
geosynthetic containers were completely sunk into the sea.
9.0.12. Based on
the investigation result, the suspected causal factors of the incident are
listed below.
·
The seaming work
of the 3rd geosynthetic container was conducted at night time on 27 October
2011. Insufficient light might have affected the quality of seaming work.
·
The anti-leakage
component at the bottom gate of hopper barge might have interfered the
geosynthetic container during dumping operation. The surface of geosynthetic container
contacted the bottom edge closely while it was squeezed out through the bottom
gate. The steel plate with bolts and nuts might have caused local damage to the
geosynthetic container.
9.0.13. To prevent
reoccurrence of the incident, Contractor HK/2009/01 has the following enhancements
are recommended.
·
To eliminate the
potential risk of workmanship caused by insufficient light, all the seaming
work of geosynthetic container will be carried out at day time (before 1800). Supervision
will be enhanced by increasing checking frequency.
·
To eliminate the
potential risk of damaging the geosynthetic container during dumping operation,
an additional steel rod to be welded on top of the steel plate for fixing
rubber seal at bottom gate of hopper barge.
·
Dumping
operation of Type 3 sediment is suspended until investigation report and
preventive measures are submitted and agreed by EPD.
9.0.14.
A
seawall blocks collapsing incident was occurred at Tunnel Section 4, TS4 (within
TCBR1W) under Contractor of HY/2009/15 at around 8:45 on 17 November 2011. An
immediate site inspection on the incident location was conducted at 11:30 on
that day so as to assess the potential water quality impact with respect to the
collapsed seawall and any further impact towards the nearby intake at Windsor
House (C7). Initial recommendations were provided to RSS on the formulation of
rectification plan to re-establish the seawall at on the same day. Contractor
of HY/2009/15 was drawn attention about the incident, highlighting the concern
on EP/FEP compliance and urged stop the filling operation.
9.0.15.
After
the incident occurred, double-layer silt curtain was then enclosed the collapse
edge to limit the potential dispersion of the unprotected edge. Grab
dredger was immediately deployed to start removing the collapsed seawall
blocks. Total 45 out of 62 seawall blocks were removal from seabed until 25
November 2011. The 24-hour turbidity monitoring data and daily SS monitoring at
C7 on the incident date onwards were reviewed and no immediate impact on water
quality was observed from the data trend. The details of the data trend are
enclosed in Appendix
5.4.
9.0.16.
It
is anticipated that the removal of collapsed seawall blocks will be completed and
a detailed diver inspection together with independent hydrographic survey will
be conducted in December 2011. Follow-up action will be taken and reported in
the coming reporting month.
10.0.1. 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.
