Section 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
·
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

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.

Noise Monitoring
Parameters, Frequency and Duration
4.1.2.
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.
4.1.3.
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.
4.1.4.
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.
Monitoring Equipment
4.1.5.
As referred to in the Technical Memorandum ™ issued under the NCO, sound
level meters in compliance with the International Electrotechnical Commission
Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be
used for carrying out the noise monitoring. Immediately prior to and following
each noise measurement the accuracy of the sound level meter shall be checked
using an acoustic calibrator generating a known sound pressure level at a known
frequency. Measurements may be accepted as valid only if the calibration level
from before and after the noise measurement agree to within 1.0 dB.
4.1.6.
Noise measurements shall not be made in fog, rain, wind with a steady
speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall
be checked with a portable wind speed meter capable of measuring the wind speed
in m/s.

performed by the laboratory was be demonstrated to the satisfaction of
the ER and IEC. IEC shall regularly audit to the measurement performed by the
laboratory to ensure the accuracy of measurement results.
4.2.9.
Filter paper of size 8” x 10” shall be labelled before sampling. It
shall be a clean filter paper with no pinholes, and shall be conditioned in a
humidity-controlled chamber for over 24-hours and be pre-weighed before use for
the sampling.
4.2.10.
After sampling, the filter paper loaded with dust shall be kept in a
clean and tightly sealed plastic bag. The filter paper shall then be returned
to the laboratory for reconditioning in the humidity controlled chamber
followed by accurate weighing by an electronic balance with readout down to 0.1
mg. The balance shall be regularly calibrated against a traceable standard.
4.2.11.
All the collected samples shall be kept in a good condition for 6 months
before disposal.
impact monitoring for
odour patrol
4.2.12.
Odour patrols along the shorelines of Causeway Bay Typhoon Shelter and
ex-Wan Chai Public 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
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 4.1.
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 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.
Water Quality Monitoring Stations
4.3.3.
Water quality monitoring was undertaken at 8 monitoring stations for WSD
salt water intakes and cooling water intakes along the seafront of the Victoria
Harbour in the reporting month. The proposed water quality monitoring stations
of the Project are shown in Table 4.3 and Figure 4.1. Appendix 4.1
shows the established Action/Limit Levels for the monitoring works.

Remarks:
1. Enhanced DO monitoring at Windsor House Cooling (Station Ref: C7) was temporarily suspended since 22 October 2014 with respect to the formation of temporary reclamation zone TS3 and to be resumed upon removal of the respective temporary reclamation zone.
5.3.23
There was 2 limit level of turbidity exceedances and 1 action level of
suspended solid exceedance recorded at monitoring station C7 on 21 June 2017.
5.3.24
Removal of seawall block opposite to the monitoring location was
conducted during the monitoring period on 21 June 2017 and turbid dispersion
was observed generated from the works area and affecting the water quality at
the concerned Windsor House cooling water intake during monitoring sampling.
5.3.25
As such, it was considered that turbidity and suspended solid
exceedances were related to Project works and the Contractor was immediately
advised to take immediate action to rectify the defects observed and conduct an
remediation plan on checking the water holding tank and silt screen installed
at the concerned monitoring location to ensure the water quality of the
concerned location would not be adversely affected.
5.3.26
Rectification measures including reinstatement of deployed impermeable
barriers and silt curtain, conducting cleaning and inspection of silt screen
and silt curtain at the concerned water intake location at implement water
flushing at the concerned water intake storage tank were observed implemented
by 23 June 2017. Additional monitoring in accordance with the Event and Action
Plan was conducted on 22 June 2017 and limit level exceedance of water
turbidity was recorded. No further turbidity exceedance was recorded on the
subsequent monitoring conducted on 23 June 2017, and no further suspended solid
exceedance was recorded on the subsequent monitoring on 23 June 2017.
5.3.27
There was 1 limit level of turbidity exceedance recorded at monitoring
station C7 on 23 June 2017.
5.3.28
After checking with the Contractor, despite D-wall excavation at TS3E
was conducted on the monitoring date, Contractor mitigation measures such as
deployment of impermeable barriers and silt curtain was generally in order, and
the installed silt screen at the concerned water intake location was generally
in order. No particular observation regarding water quality impact was observed
during monitoring sampling period. In view of the above, it is considered that
there was no information to suggest the exceedance was related to Project
works.
5.3.29
There was 1 limit level of turbidity exceedance and 1 action level of
suspended solid recorded at monitoring station C7 on 26 June 2017.
5.3.30
Underwater excavation at TS3E was conducted during the monitoring period
on 26 June 2017. Owing to the malfunctioning of seawater pump on 26 June 2017
flood tide, fresh water was directly supplied to the storage holding tank for
water supply to Windsor House Intake. Subsequently, during the sampling event
on 26 June 2017 during ebb tide, turbidity
and suspended solid exceedances were recorded at the water holding tank
and hence it was considered potential contamination within water holding tank
with direct freshwater supply by Project works site and affecting the water
quality at the concerned Windsor House cooling water intake.
5.3.31
As such, it was considered that the turbidity and suspended solid
exceedances were related to Project works and the Contractor was immediately
advised to take immediate action to rectify the water quality concerned
observed and prepare the remediation plan according to the Event and Action
Plan to address the water quality concern. Remedial measures including
reflushing the concerned water intake location were implemented on 27 June
2017. Additional monitoring in accordance with the Event and Action Plan was
conducted on 27 June 2017 and no further turbidity exceedance was recorded. No
further suspended solid exceedance was recorded on the subsequent monitoring on
28 June 2017.

by 23 June 2017. Additional monitoring in accordance with the Event and Action
Plan was conducted on 22 June 2017 and limit level exceedance of water
turbidity was recorded. No further turbidity exceedance was recorded on the
subsequent monitoring conducted on 23 June 2017, and no further suspended solid
exceedance was recorded on the subsequent monitoring on 23 June 2017.
6.3.10
There was 1 limit level of turbidity exceedance recorded at monitoring
station C7 on 23 June 2017.
6.3.11
After checking with the Contractor, despite D-wall excavation at TS3E
was conducted on the monitoring date, Contractor mitigation measures such as
deployment of impermeable barriers and silt curtain was generally in order, and
the installed silt screen at the concerned water intake location was generally
in order. No particular observation regarding water quality impact was observed
during monitoring sampling period. In view of the above, it is considered that
there was no information to suggest the exceedance was related to Project
works.
6.3.12
There was 1 limit level of turbidity exceedance and 1 action level of
suspended solid recorded at monitoring station C7 on 26 June 2017.
6.3.13
Underwater excavation at TS3E was conducted during the monitoring period
on 26 June 2017. Owing to the malfunctioning of seawater pump on 26 June 2017
flood tide, fresh water was directly supplied to the storage holding tank for
water supply to Windsor House Intake. Subsequently, during the sampling event
on 26 June 2017 during ebb tide, turbidity and suspended solid exceedances were
recorded at the water holding tank and hence it was considered potential
contamination within water holding tank with direct freshwater supply by
Project works site and affecting the water quality at the concerned Windsor
House cooling water intake.
6.3.14
As such, it was considered that the turbidity and suspended solid exceedances
were related to Project works and the Contractor was immediately advised to
take immediate action to rectify the water quality concerned observed and
prepare a remediation plan according to the Event and Action Plan to address
the water quality concern. Remedial measures including reflushing the concerned
water intake location were implemented on 27 June 2017. Additional monitoring
in accordance with the Event and Action Plan was conducted on 27 June 2017 and
no further turbidity exceedance was recorded. No further suspended solid
exceedance was recorded on the subsequent monitoring on 28 June 2017.
6.4.1
There was no non-compliance from the site audits in the reporting
period. The observations and recommendations made in each individual site audit
session were presented in Section 8.
6.4.2
There was 2 limit level of turbidity exceedances and 1 action level of
suspended solid exceedance recorded at monitoring station C7 on 21 June 2017. Removal
of seawall block opposite to the monitoring location was conducted during the
monitoring period on 21 June 2017 and turbid dispersion was observed generated
from the works area and affecting the water quality at the concerned Windsor
House cooling water intake during monitoring sampling. As such, it was
considered that turbidity and suspended solid exceedances were related to
Project works.
6.4.3
There was 1 limit level of turbidity exceedance and 1 action level of
suspended solid recorded at monitoring station C7 on 26 June 2017. Underwater
excavation at TS3E was conducted during the monitoring period on 26 June 2017.
Owing to the malfunctioning of seawater pump on 26 June 2017 flood tide, fresh
water was directly supplied to the storage holding tank for water supply to
Windsor House Intake. Subsequently, during the sampling event on 26 June 2017
during ebb tide, turbidity and suspended solid exceedances were recorded at the
water holding tank and hence it was considered potential contamination within
water holding tank with direct freshwater supply by Project works site and
affecting the water quality at the concerned Windsor House cooling water
intake. As such, it was considered that the turbidity and suspended solid exceedances were
related to Project works
6.5.1
Immediate report in-situ measurement has confirmed the exceedance
recorded at C7 on 21 June 2017. The Contractor was immediately advised to take immediate action to
rectify the defects observed and conduct a remediation plan on checking the
water holding tank and silt screen installed at the concerned monitoring
location to ensure the water quality of the concerned location would not be
adversely affected. Rectification measures including reinstatement of deployed
impermeable barriers and silt curtain, conducting cleaning and inspection of
silt screen and silt curtain at the concerned water intake location at
implement water flushing at the concerned water intake storage tank were
observed implemented by 23 June 2017. Additional monitoring in accordance with
the Event and Action Plan was conducted on 22 June 2017 and limit level
exceedance of water turbidity was recorded. No further turbidity exceedance was
recorded on the subsequent monitoring conducted on 23 June 2017, and no further
suspended solid exceedance was recorded on the subsequent monitoring on 23 June
2017.
