1.1.1.
Lam Geotechnics Limited (LGL) has
been appointed to work as the
Environmental Team (ET) for Contractor No. HK/2009/05
Wan Chai Development Phase II and Central –Wan Chai Bypass Sampling, Field
Measurement and Testing Work (Stage 1) to implement the 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).

auditing work carried out in accordance to the Section
10.3 of EM&A Manual
and /span>Environmental Monitoring and Audit
Requirements /span>
under Particular Specification Section 27.

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 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.

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.

4.1.2.
Reviewed the past
monitoring results and observation at Station M4a, the monitoring location at
Causeway Bay Community Centre is facing and closed to the Island Eastern Corridor.
Traffic noise is the major noise source obtained in the monitoring that cannot
be reflected the fact of the construction noise from the construction site.
Victoria Centre (Station ID: M4b) is proposed as alternative noise monitoring station,
which is more appropriate and representative as noise monitoring station for
monitoring the construction noise arising from the near construction site.
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.
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
4.1.6.
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.
4.1.7.
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.
4.1.8.
The sound level meter shall be checked using
an acoustic calibrator generating a known sound pressure level at a known
frequency before deployment to the site and during each site visit.
Measurements may be accepted as valid only if the calibration level from before
and after the noise measurement agree to within 1.0 dB.
Air Quality Monitoring Stations
4.2.1.
The air monitoring stations for the Project
are listed and shown in Table 4.2 and Figure 4.1. Appendix 4.1 shows the established
Action/Limit Levels for the monitoring works.

Air Monitoring Parameters, Frequency and
Duration
4.2.2.
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.
4.2.3.
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.
4.2.4.
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
4.2.5.
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;
-
easily changeable filter; and
-
capable of operating continuously for a
24-hour period.
4.2.6.
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
4.2.7.
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.
4.2.8.
Filter paper of size 8" x 10" shall
be labeled 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.
4.2.9.
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.
4.2.10. All
the collected samples shall be kept in a good condition for 6 months before
disposal.
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.
Water Quality Monitoring Stations
4.3.2.
It is proposed to monitor the water quality
at 9 WSD salt water intakes and 12 cooling water intakes along the seafront of
the Victoria Harbour. 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.

Water Quality Parameters
4.3.3.
Monitoring of dissolved oxygen (DO),
turbidity and suspended solids (SS) shall be carried out at WSD flushing water
intakes and cooling water intakes. DO and Turbidity are measured in-situ while
SS is determined in laboratory.
4.3.4.
In association with the water quality
parameters, other relevant data shall also be measured, such as monitoring
location/position, time, sampling depth, water temperature, pH, salinity,
dissolved oxygen (DO) saturation, weather conditions, sea conditions, tidal
stage, and any special phenomena and work underway at the construction site
etc.
Sampling Procedures and Monitoring
Equipment
4.3.5.
The interval between two sets of monitoring
should not be less than 36 hours except where there are exceedances of Action
and/or Limit Levels, in which case the monitoring frequency will be
increased. Table 4.4 shows the

water sampler comprises a transparent PVC cylinder, with a capacity of not less
than 2 litres, and can be effectively sealed with latex cups at both ends. The sampler should have a positive latching
system to keep it open and prevent premature closure until released by a messenger
when the sampler is at the selected water depth (e.g. Kahlsico Water Sampler or
an approved similar instrument).
Sample Container and Storage
4.3.11. Water
samples for suspended solids measurement should be collected in high-density
polythene bottles, packed in ice (cooled to 4°C without being frozen), and
delivered to ALS Technichem (HK) Pty Ltd. as soon as possible after collection
for analysis.
Water Depth Detector
4.3.12. A
portable, battery-operated echo sounder shall be used for the determination of
water depth at each designated monitoring station. This unit can either be handheld or affixed to the bottom of the
workboat, if the same vessel is to be used throughout the monitoring programme.
Salinity
4.3.13. A
portable salinometer capable of measuring salinity in the range of 0-40 ppt
shall be provided for measuring salinity of the water at each of monitoring
location.

point bearing indication or other equivalent instrument of similar accuracy
shall be provided and used during monitoring to ensure the monitoring vessel is
at the correct location before taking measurements.
Calibration of In-situ Instruments
4.3.15. All
in-situ monitoring instrument shall be checked, calibrated and certified by a
laboratory accredited under HOKLAS or equivalent before use, and subsequently
re-calibrated at 3 monthly intervals throughout all stages of the water quality
monitoring. Responses of sensors and electrodes should be checked with
certified standard solutions before each use.
Wet bulb calibration for a DO meter shall be carried out before
measurement at each monitoring location.
4.3.16. For
the on site calibration of field equipment by the ET, the BS 127:1993,
"Guide to Field and on-site test methods for the analysis of waters"
should be observed.
4.3.17. Sufficient
stocks of spare parts should be maintained for replacements when
necessary. Backup monitoring equipment
shall also be made available so that monitoring can proceed uninterrupted even
when some equipment is under maintenance, calibration, etc.
4.3.18. Current
calibration certificates of equipments are presented in Appendix
4.2.
Laboratory Measurement / Analysis
4.3.19. Analysis
of suspended solids has been carried out in a HOKLAS accredited laboratory, ALS
Technichem (HK) Pty Ltd. Water samples
of about 1L shall be collected at the monitoring stations for carrying out the
laboratory SS determination. The SS
determination work shall start within 24 hours after collection of the water
samples. The SS determination shall
follow APHA 19ed or equivalent methods subject to the approval of IEC and EPD.
5.0.1.
The environmental monitoring will be
implemented based on the division of works areas of each designed project
managed under different contracts with separate FEP applied by individual
contractors. Overall layout showing
