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
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. 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.

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:

Frequency and Duration
3.2.2.
One-hour
and 24-hour TSP levels should be measured to indicate the impacts of
construction dust on air quality. The 24-hour TSP levels shall be measured by
following the standard high volume sampling method as set out in the Title 40
of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B.
3.2.3.
All
relevant data including temperature, pressure, weather conditions, elapsed-time
meter reading for the start and stop 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.
Sampling Procedure and
Monitoring Equipment
3.2.5 High
volume samplers (HVSs) in compliance with the following specifications shall be
used for carrying out the 1-hour and 24-hour TSP monitoring:
·
0.6
- 1.7 m3 per minute adjustable flow range;
·
equipped
with a timing / control device with +/- 5 minutes accuracy for 24 hours
operation;
·
installed
with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;
·
capable
of providing a minimum exposed area of 406 cm2;
·
flow
control accuracy: +/- 2.5% deviation over 24-hour sampling period;
·
equipped
with a shelter to protect the filter and sampler;
·
incorporated
with an electronic mass flow rate controller or other equivalent devices;
·
equipped
with a flow recorder for continuous monitoring;
·
provided
with a peaked roof inlet;
·
incorporated
with a manometer;
·
able
to hold and seal the filter paper to the sampler housing at horizontal
position;
·

·
capable
of operating continuously for a 24-hour period.
3.2.6 Initial
calibration of dust monitoring equipment shall be conducted upon installation
and thereafter at bi-monthly intervals. The transfer standard shall be
traceable to the internationally recognized primary standard and be calibrated
annually. The concern parties such as IEC shall properly document the
calibration data for future reference. All the data should be converted into
standard temperature and pressure condition.
Laboratory Measurement /
Analysis
3.2.7 A clean
laboratory with constant temperature and humidity control, and equipped with
necessary measuring and conditioning instruments to handle the dust samples
collected, shall be available for sample analysis, and equipment calibration
and maintenance. The laboratory should be HOKLAS accredited.
3.2.8 An
alternative non-HOKLAS
accredited laboratory was set-up for carrying out the laboratory
analysis, the laboratory equipment was approved by the ER on 8
February 2011 and
the measurement procedures were witnessed by the IEC. Any measurement 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

impact monitoring for
odour patrol
3.2.12 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
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 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
3.3.3. It is proposed to monitor the water quality at 9
WSD salt water intakes and 14 cooling water intakes along the seafront of the

5.4.2. There were
turbidity and SS exceedances recorded at C5e and C5w on 13 and 15 Oct 2012
during ebb tide. Muddy water quality appearance inside and outside silt screen
were observed during monitoring. Checking with Contractor’s work, rockfilling
near temporary seawall at WCR2 was conducted on that day. Checking with contractor's
inspection record, the silt screen and silt curtain for rockfilling were in
proper condition on that day. Although the Contractor's records have shown a
well maintained silt curtain and silt screen, muddy water was still observed
around the intake during monitoring. The
turbidity and SS concentration has returned to below the Action Level after
stopping of filling works during the flood tide. This shows possible defects at the silt
curtain and that protection around the intake is inadequate to protect the
sensitive receiver during the filling activities.
5.4.3. There were
turbidity and SS exceedances recorded at C5w on 20 October 2012 during flood
tide. Silty water was observed discharging from water pipe into Well B during
monitoring. 21.65 NTU
turbidity was recorded outside the silt screen. Contractor immediately removed
the pipe from Well B. ET reminded Contractor should ensure the water pumping
into Well for cooling purpose should not deteriorate the water quality of
intake. No further exceedance was recorded in the next consecutive water
monitoring on 22 Oct. The turbidity and SS concentration has returned to below
the Action Level after removal of water pipe.
5.4.4. There were
turbidity and SS exceedances recorded at C5e on 25 October 2012 during flood
tide. Muddy dispersion into the Well as a result of the rockfilling in WCR2 was
observed during inspection walk on 25 Oct. ET recommended that gaps at
temporary sheet pile at Well B should be sealed up and the turbid water inside
well should be treated to improve the water quality in the well. Daily water
quality monitoring at C5e was conducted on 26 Oct 12 under Event and Action
Plan. The turbidity of C5e was 7.38 NTU on 26 Oct 12 which is below Action
level. The turbidity and SS concentration has returned to below the Action
Level after the improvement of condition of temporary sheet pile at Well.
5.4.5. All exceedances in Table 5.1 have been investigated
and there was no project-related exceedance.

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 (October 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 North Point,
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 while the adverse water impact was only located in the WCR2 in
relation to the rock filling operation causing exceedances in WCR2 related to
Contract no. HK/2009/02 in October 2012. Thus, it was unlikely to have
cumulative impact from 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-compliance was noted and no prosecution was
received during the reporting period.
8.0.3. The construction programmes
of individual contracts are provided in Appendix 7.1.
