Remarks:
(1)
The
ET of this Contract should conduct impact air quality monitoring at the AMS
listed in the table as part of EM&A programme according to the latest
notification from ENPO when the monitoring station(s) is/are no longer covered
by another ET of the HZMB project. The ET of the Contract shall communicate and
share the monitoring data to the ET(s) of other works contracts if the air
quality monitoring station(s) is/are as part of EM&A programme.
5.4.2 If alternative monitoring
locations are proposed due to the situation mentioned in para 5.4.1, the
proposed site should be selected based on the following principle:
a)
Situating at the site boundary or such locations close
to the major dust emission source(s);
b)
Monitoring as close as possible to the sensitive
receptor(s);
c)
Taking into account the prevailing meteorological
conditions; and
d)
Assuring minimal disturbance to the occupants and
working under a safe condition during monitoring.
5.4.3 The ET shall agree with the ER
in consultation with the IEC on the position of the HVS for the installation of
the monitoring equipment. When positioning the samplers, the following points
shall be noted:
a)
a horizontal platform with appropriate support to
secure the samplers against gusty wind should be provided;
b)
no two samplers should be placed less than 2 meters
apart;
c)
the distance between the sampler and an obstacle, such
as buildings, must be at least twice the height that the obstacle protrudes
above the sampler;
d)
a minimum of 2 meters of separation from walls,
parapets and penthouses is required for rooftop samplers;
e)
a minimum of 2 meters separation from any supporting
structure, measured horizontally is required;
f)
no furnace or incinerator flue is nearby;
g)
airflow around the sampler is unrestricted;
h)
the sampler is more than 20 meters from the dripline;
i)
any wire fence and gate, to protect the sampler,
should not cause any obstruction during monitoring;
j)
permission must be obtained to set up the samplers and
to obtain access to the monitoring stations; and
k)
a secured supply of electricity is needed to operate
the samplers.
5.4.4 The ENPO may, depending on site
conditions and monitoring results, decide whether additional monitoring
locations shall be included or any monitoring locations could be removed/
relocated during any stage of the construction phase.
5.5.1 Baseline monitoring shall be
carried out at all of the designated monitoring locations (see Table 5.1) for
at least 14 consecutive days prior to the commissioning of major construction
works to obtain daily 24-hour TSP samples. The selected baseline monitoring
stations should reflect baseline conditions at the impact stations. One-hour
sampling should also be done at least 3 times per day while the highest dust
impact is expected.
5.5.2 During the baseline monitoring,
there should not be any major construction or dust generation activities in the
vicinity of the monitoring stations. Before commencing baseline monitoring, the
ET shall inform the IEC of the baseline monitoring programme such that, if
required, the ER can conduct on-site audit to ensure accuracy of the baseline
monitoring results.
5.5.3 In case the baseline monitoring
cannot be carried out at the designated monitoring locations, the ET Leader
shall carry out the monitoring at alternative locations that can effectively
represent the baseline conditions at the impact monitoring locations. The
alternative baseline monitoring locations shall be approved by the ER and
agreed with the IEC.
5.5.4 In exceptional cases, when
insufficient baseline monitoring data or questionable results are obtained, the
ET shall liaise with the IEC and EPD to agree on an appropriate set of data to
be used as a baseline reference and submit to ER for approval.
5.5.5 Ambient conditions may vary
seasonally and shall be reviewed once every three months. When the ambient
conditions have changed and a repeat of the baseline monitoring is required to
be carried out for obtaining the updated baseline levels, the monitoring should
be at times when the Contractor's activities are not generating dust, at least
in the proximity of the monitoring stations. Should change in ambient
conditions be determined, the baseline levels and, in turn, the air quality
criteria, should be revised. The revised baseline levels and air quality
criteria should be agreed with the IEC and EPD.
5.5.6 It is noted that baseline
monitoring was undertaken for the Project between September and November 2011
under Agreement CE No. 35/2011 (EP) Baseline Environmental monitoring for Hong
Kong – Zhuhai – Macao Bridge Hong Kong Projects – Investigation prior to the
construction of the Project. The
baseline monitoring results obtained under Agreement CE No. 35/2011(EP) will be
adopted for this Contract.
5.6.1 The
ET shall carry out impact monitoring during the entire construction period. For
regular impact monitoring, the sampling frequency of at least once in every 6
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 3
times in every 6 days should be undertaken when the highest dust impact occurs.
Before commencing impact monitoring, the ET shall inform the IEC of the impact
monitoring programme such that the IEC can conduct on-site audit to ensure
accuracy of the monitoring results.
5.6.2 The
specific time to start and stop the 24-hour TSP monitoring shall be clearly
defined for each location and be strictly followed by the ET.
5.6.3 In
case of non-compliance with the air quality criteria, more frequent monitoring,
as specified in the Action Plan in the following section, shall be conducted
within the specified timeframe after the result is obtained. This additional
monitoring shall be continued until the excessive dust emission or the
deterioration in air quality is rectified, and agreed with the ER and the IEC.
5.7.1 The
baseline monitoring results form the basis for determining the air quality
criteria for the impact monitoring. The ET shall compare the impact monitoring
results with air quality criteria set up for 24-hour TSP and 1-hour TSP. Table 5.2 shows the air quality
criteria, namely Action and Limit levels to be used.

5.9.1 The approved EIA Report has
recommended dust control measures including 8 times of watering per day. Good
site practices such as road surface paving, dust enclosures, wheel wash
facilities would be implemented to reduce the generation of dust.
5.9.2 All
the proposed mitigation measures are summarized in the Environmental Mitigation
Implementation Schedule (EMIS) in Appendix
C.
5.10.1 The
Assignment, which involves multiple construction contracts, would be
constructed concurrently with other major infrastructures such as the HKLR and
TM-CLKL. These interface projects will be overviewed by the ENPO. The ENPO will
also oversee and coordinate the cumulative environmental issues arising from
the concurrent projects.
5.10.2 To
facilitate the ENPO to evaluate environmental impacts and investigate
complaints, the ET Leaders shall provide the impact air quality monitoring
results within one week after the monitoring event. If the 1-Hr TSP is measured
by direct reading, the results shall be submitted to ENPO in the next working
day. The ET Leader shall follow ENPO's requirements on the data submission
format and procedure" as per the current ET's practice and enable rapid
response by all concerned parties.
6.1.1 Construction
noise level shall be measured in terms of the A-weighted equivalent continuous
sound pressure level (Leq). Leq, 30 mins 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 min shall be
employed for comparison with the Noise Control Ordinance (NCO) criteria.
6.1.2 As
supplementary information for data auditing, statistical results such as L10
and L90 shall also be obtained for reference.
6.2.1 As
referred to in the Technical Memorandum (TM) 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 agrees to within
1.0 dB.
6.2.2 Noise
measurements should be made in accordance with standard acoustical principles
and practices in relation to weather conditions.
6.2.3 The
ET is responsible for the provision, installation, operation, maintenance,
dismantle of the monitoring equipment. He shall ensure that sufficient noise
measuring equipment and associated instrumentation are available for carrying
out the baseline monitoring, regular impact monitoring and ad hoc
monitoring. All the equipment and
associated instrumentation shall be clearly labeled.
6.2.4 Due
to rejection from Ho Yu College (NMS3) for setting up a noise monitoring
station at their school, an alternative location at site boundary of the ER’s
site office area at Works Area WA2 (NMS3B) is proposed. Same baseline and
Action and Limit Levels for noise, as derived from the baseline monitoring data
recorded at Ho Yu College, will be adopted for this alternative noise
monitoring location.
6.3.1 The
location of construction noise monitoring stations for the Contract are
presented in Table 6.1 and shown in Figure 2.

Remarks:
(1) The
ET of this Contract should conduct impact noise monitoring at the NMS listed in
the table as part of EM&A programme according to the latest notification
from ENPO when the monitoring station(s) is/are no longer covered by another ET
of the HZMB project. The ET of the
Contract shall communicate and share the monitoring data to the ET(s) of other
works contracts if the noise monitoring station(s) is/are as part of EM&A
programme.
(2) The
Action and Limit Levels for schools will be applied for this alternative
monitoring location.
6.3.2 The
ET shall select the monitoring location from the above table based on the
locations of the construction activities and seek approval from ER and
agreement from the IEC and EPD to the proposal. The monitoring location should
be chosen based on the following criteria:
l at locations close to the
major site activities which are likely to have noise impacts;
l close to the most affected
existing noise sensitive receivers; and
l for monitoring locations
located in the vicinity of the sensitive receivers, care should be taken to
cause minimal disturbance to the occupants during monitoring.
6.3.3 The
monitoring station shall normally be at a point 1 m from the exterior of the
sensitive receiver building facade and be at a position 1.2 m above the
ground. If there is problem with
access to the normal monitoring position, an alternative position may be
chosen, and a correction to the measurements shall be made. For reference, a
correction of +3 dB(A) shall be made to the free field measurements. The ET
shall agree with the IEC on the monitoring position and the corrections
adopted. Once the positions for the monitoring stations are chosen, the
baseline monitoring and the impact monitoring shall be carried out at the same
position.
6.3.4 The
ENPO may, depending on site conditions and monitoring results, decide whether
additional monitoring locations shall be included or any monitoring locations
could be removed/ relocated during any stage of the construction phase.
6.4.1 The
ET shall carry out baseline monitoring prior to the commencement of the
construction works. There shall not be any construction activities in the
vicinity of the stations during the baseline monitoring. Continuous baseline
noise monitoring for the A-weighted levels Leq, L10 and L90
shall be carried out daily for a period of at least two weeks in a sample
period of 5 minutes or 30 minutes between 07:00 and 19:00, and 5 minutes
between 19:00 and 07:00. A schedule on the baseline monitoring shall be
submitted to the ER and IEC for approval before the monitoring starts.
6.4.2 In
exceptional cases, when insufficient baseline monitoring data or questionable
results are obtained, the ET shall liaise with the IEC and EPD to agree on an
appropriate set of data to be used as a baseline reference and submit to the ER
for approval.
6.4.3 It
is noted that baseline monitoring was undertaken for the Project between
September and November 2011 under Agreement CE No. 35/2011 (EP) Baseline
Environmental monitoring for Hong Kong – Zhuhai – Macao Bridge Hong Kong
Projects – Investigation prior to the construction of the Project. The baseline monitoring results obtained
under Agreement CE No. 35/2011(EP) will be adopted for this Contract.
6.5.1 During
normal construction working hour (07:00-19:00 Monday to Saturday), monitoring
of Leq, 30 minutes noise levels (as six consecutive Leq,
5 minutes readings) shall be carried out at the agreed monitoring locations
once every week in accordance with the methodology in the TM.
6.5.2 If
a school exists near the construction activity, noise monitoring shall be
carried out at the monitoring stations for the schools during the school
examination periods. The ET Leader shall liaise with the school’s personnel and
the Examination Authority to ascertain the exact dates and times of all
examination periods during the course of the contract.
6.5.3 In
case of non-compliance with the construction noise criteria, more frequent
monitoring, as specified in the Action Plan, shall be carried out. This
additional monitoring shall be continued until the recorded noise levels are
rectified or proved to be irrelevant to the construction activities.
6.5.4 A
schedule on the compliance monitoring shall be submitted to the ER and IEC for
approval before the monitoring starts.
6.6.1 The
Action and Limit Levels for construction noise are defined in Table 6.2. Should non-compliance of the
criteria occur, actions in accordance with the Action Plan in Table 6.3 shall be carried out.

6.7.1 The EIA Report has recommended
construction noise control measures including the use of quiet plant and
temporary noise barriers. All the
proposed mitigation measures are summarised in the EMIS in Appendix C.
6.7.2 Not applicable.
6.7.3 The recommended noise control
measures are summarized as follows:-
l Good site practices and
noise management techniques;
l Use of site hoarding;
l Use of movable noise
barrier and full enclosure for relatively static plant;
l Use of “quiet” plant and
working methods;
l Sequencing operation of
construction plant equipment; and
l Rescheduling to avoid noise
construction works during school examination.
6.8.1 The Assignment, which involves
multiple construction contracts, would be constructed concurrently with other
major infrastructures such as the HKLR and TM-CLKL. These interface projects
will be overviewed by the ENPO. The ENPO will also oversee and coordinate the
cumulative environmental issues arising from the concurrent projects.
To
facilitate the ENPO to evaluate environmental impacts and investigate
complaints, the ET Leaders shall provide the impact noise monitoring results
within one working day after the monitoring event. The ET Leader shall follow
ENPO’s requirement on the data submission format and procedure.
7.1.1 The

investigation for sediment quality in relation to the current study area for
HKBCF and HKLR is summarized in the EIA Report, there is no requirement on
environmental monitoring and audit for sediment quality.
7.1.2 The
requirements as recommended in ETWB TC 34/2002 Management of Dredged/Excavated
Sediment shall be included in the Particular Specification as appropriate for
sediment disposal.
8.1.1 The quantity and timing of the
generation of waste during the construction phase have been estimated. Measures including the opportunity for
on-site sorting, reusing excavated materials for reclamation etc. are devised
in the construction methodology to minimise the surplus materials to be
disposed off-site. Proper disposal of chemical waste should be via a licensed
waste collector.
8.1.2 All the proposed mitigation
measures are stipulated in the EIA Report and summarized in the EMIS in Appendix C.
8.1.3 The types and quantities of
waste that would be generated during the operational phase have been assessed.
It is anticipated there would not be any insurmountable impacts during the
operation phase. A trip-ticket system should be operated to monitor all
movements of chemical wastes which will be collected by a licensed collector to
a licensed facility for final treatment and disposal.
8.1.4 Recommendations have been made
to ensure proper treatment and proper disposal of these wastes in the EIA
Report and all the proposed mitigation measures are stipulated in the EIA
Report are summarised in the EMIS in Appendix
C.
8.1.5 EM&A requirements are
required for waste management during the construction phase only and the
effective management of waste arising during the construction phase will be
monitored through the site audit programme. The aims of the waste audit are:
l to ensure the waste arising
from the works are handled, stored, collected, transferred and disposed of in
an environmentally acceptable manner; and
l to encourage the reuse and
recycling of material.
8.2.1 The Contractor shall be required
to pay attention to the environmental standard and guidelines and carry out
appropriate waste management and obtain the relevant licence/permits for waste
disposal. The ET shall ensure that the Contractor has obtained from the
appropriate authorities the necessary waste disposal permits or licences
including:
l Chemical Waste Permits/licenses
under the Waste Disposal Ordinance (Cap 354);
l Public Dumping Licence
under the Land (Miscellaneous Provisions) Ordinance (Cap 28);

under the Water Pollution Control Ordinance.
8.2.2 The Contractor shall refer to
the relevant booklets issued by the DEP when applying for the licence/permit
and the ET shall refer to these booklets for auditing purposes.
8.2.3 During the site inspections and
the document review procedures, the ET shall pay special attention to the
issues relating to waste management and check whether the Contractor has
followed the relevant contract specifications and the procedures specified
under the laws of Hong Kong. In addition to the site inspections, the ET shall
review the documentation procedures prepared by the Waste Coordinator once a
week to ensure proper records are being maintained and procedures undertaken in

9.1.1A The
EIA Report has assessed the water quality impacts caused by the construction
and operation stages. Mitigation measures have been recommended in the EIA to
ensure compliance with the relevant legislative requirements. The hanging-type
silt-curtain will be deployed around the site during marine work is carry out.
9.1.2 Prior
to the commencement of the construction work, a detailed site drainage
management plan should be submitted to EPD. The plan should cover measures to
minimize all potential water quality impact arising from the surface runoffs of
all the related constructions.
9.1.3 The
guidelines outlined in the Practice Note for Professional Persons Environmental
Consultative Committee (ProPECC), Construction Site Drainage (PN 1/94) should
be adopted to control construction site runoff. Mitigation measures to minimise
water quality impacts from construction site runoff and wastewater and sewage
generated from construction activities are:
l Provision of site drainage
systems over the entire construction site with sediment control facilities.
Regular inspection and maintenance of the site drainage systems are required to
ensure proper and efficient operation at all times.
l Sedimentation tanks or
package treatment systems are required to treat the large amount of
sediment-laden wastewater generated from foundation construction work, wheel
washing, site runoff. Any construction activities that generate wastewater with
high concentrations of suspended solid (SS) should also be collected to these
facilities for proper treatment prior to disposal. Treated wastewater can be
reused for vehicle washing, dust suppression and general cleaning.
l The construction programme
should be properly planned to avoid soil excavation in rainy seasons. Exposed
stockpiles of excavated soils or construction materials should be covered with
tarpaulin or impervious sheets to avoid release of pollutants into the drainage
channels.
l Sewage generated from site
toilets and canteen should be collected using a temporary storage system.
Chemical toilets should be provided at different locations for use by the
workers on site. Licensed waste collectors should be employed for collection
and disposal of the sewage. The drainage system for collection of wastewater
generated from canteen, if any, should be equipped with grease trap capable of
providing at least 20 minutes retention during peak flow.
l Wheel washing facilities
should be installed at all site entrances/exits.
l An emergency plan should be
developed by the contractors to deal with accidental spillage of chemicals.
9.1.4 Upon
completion of the HKBCF development, stormwater drainage systems would be
completed to collect stormwater generated from the whole area including new
roads. Sewage generated from the
HKBCF development would be treated on site to fulfill effluent limit for
discharge. Additional mitigation
measures would not be required.
9.1.5A Marine water quality
monitoring shall be carried out during the construction phase to ensure that
any unacceptable increase in suspended solids / turbidity and decrease in dissolved
oxygen due to dredging and filling activities could be readily detected and
timely action bIe taken to rectify the situation.
9.1.6 Dissolved
oxygen (DO), turbidity (NTU), suspended solids (SS) and other general in situ
parameters shall be monitored at all designated marine water quality monitoring
stations during the whole construction period. DO and turbidity should be
measured in-situ whereas SS should be determined by an accredited laboratory.
9.1.7 Other
relevant data shall also be recorded, including monitoring location / position,
time, water depth, pH value, salinity, temperature, tidal stages, weather
conditions and any special phenomena or work underway at the construction site.
9.1.8 According
to the EIA report, there is low concentration for PAH, PCB, TBT, and
chlorinated pesticides. Monitoring of these chemicals would not be required
during the construction stage.
9.1.9 The
proposed water quality monitoring schedule shall be submitted to EPD at least 2
weeks before the first day of the monitoring month. EPD shall also be notified
immediately for any changes in schedule by fax.
Dissolved Oxygen and Temperature Measuring
Equipment
9.2.1 The
instrument should be a portable and weatherproof dissolved oxygen (DO)
measuring instrument complete with cable and sensor, and use a DC power source.
The equipment should be capable of measuring: �h
·
a
DO level in the range of 0 - 20 mg/ L and 0 - 200% saturation; and �h
·
a
temperature of 0 - 45 degree Celsius.
9.2.2 It
should have a membrane electrode with automatic temperature compensation
complete with a cable.
9.2.3 Should
salinity compensation not be built-in to the DO equipment, in-situ salinity
should be measured to calibrate the DO equipment prior to each DO measurement.
Turbidity Measurement Instrument
9.2.4 The instrument should be a portable
and weatherproof turbidity measuring instrument using a DC power source. It
should have a photoelectric sensor capable of measuring turbidity between 0 -
1000 NTU (for example, Hach model 2100P or an approved similar instrument).
Sampler
9.2.5 A water sampler is required. It should
comprise a transparent PVC cylinder, with a capacity of not less than 2 litres,
which 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 (for example, Kahlsico Water Sampler or an approved similar instrument)
Water Depth Detector
9.2.6 A portable, battery-operated echo
sounder should be used for the determination of water depth at each designated
monitoring station. This unit can either be hand held or affixed to the bottom
of the work boat, if the same vessel is to be used throughout the monitoring
programme.
Salinity
9.2.7 A portable salinometer capable of
measuring salinity in the range of 0 - 40 parts per thousand (ppt) should be
provided for measuring salinity of the water at each monitoring location.
pH Measuring Equipment
9.2.8 A portable pH meter capable of
measuring a range between 0.0 and 14.0 shall be provided to measure pH under
the specified conditions (e.g., Orion Model 250A or an approved similar
instrument)
Sample Containers and Storage
9.2.9 Water samples for SS determinations
should be stored in high density polythene bottles with no preservative added,
packed in ice (cooled to 4°C without being frozen) and delivered to the
laboratory within 24 hours of collection and be analysed as soon as possible
after collection.
Monitoring Position Equipment
9.2.10 A hand-held or boat-fixed type digital Differential
Global Positioning System (DGPS) with way point bearing indication and Radio
Technical Commission for maritime (RTCM) Type 16 error message ‘screen pop-up’
facilities (for real-time auto-display of error messages and DGPS corrections
from the Hong Kong Hydrographic Office), or other equipment instrument of
similar accuracy, should be provided and used during marine water monitoring to
ensure the monitoring vessel is at the correct location before taking
measurements.
Calibration on In-Situ Instruments
9.2.11 The pH meter, DO meter and turbidimeter shall be checked
and calibrated before use. DO meter and turbidimeter shall be certified by a
laboratory accredited under HOKLAS or any other international accreditation
scheme, 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.
Back-up Equipment and Vessels
9.2.12 Sufficient stocks of spare parts shall 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. For the on site calibration of field
equipment, the BS127:1993, "Guide to Field and on-site test methods for the analysis of waters" shall be observed
9.2.13 The Water Quality Monitoring will involve a large number
of monitoring stations and measurements should be conducted within the
prescribed tidal conditions (within ± 1.75 hour of the predicted mid-ebb or mid-flood tides) in
order to ensure the measurement/samples are representative. A multiprobe
monitoring equipment set integrated with water sampler(s) is highly recommended
to improve the monitoring efficiency. It is, also, likely that more than one
field survey vessels will be required simultaneously to ensure the monitoring
are conducted within the acceptable monitoring windows. The ET shall also
consider the use of unattended automatic sampling/monitoring devices at fixed
stations where monitoring are required throughout the construction period. The
use of such unattended automatic devices, however, shall be subject to the
approval of the ER, IEC and EPD.
9.3.1 Duplicate samples from each
independent sampling event are required for SS measurement, which shall be
carried in a HOKLAS or other international accredited laboratory. Sufficient
water samples (of about 1L) shall be collected at the monitoring stations for
carrying out the laboratory measurement and analysis. The laboratory
determination work shall start within 24 hours after collection of the water
samples. The analysis for SS is summarized in Table 9 .1.

9.3.2 If a site laboratory is set
up or a non-HOKLAS and non-international accredited laboratory is hired for
carrying out the laboratory analysis, the laboratory equipment, analytical
procedures, and quality control shall be approved by EPD. All the analysis
shall be witnessed by the ER. The ET Leader shall provide the ER with one copy
of the relevant chapters of the “APHA Standard Methods for the Examination of
Water and Wastewater” 19th edition and any other relevant document for his
reference.
9.4.1 The water quality monitoring stations,
control stations and locations for during the construction and operation phase
of HKBCF are shown in Figure 3. The
demarcation of the monitoring stations for different projects will be further
determined by the ENPO before the commencement of the construction. The
selections of these stations are based on the following criteria:
(i) Impact stations (IS) within 250m – 500m envelope of the
construction works. (i.e. 3 impact locations)
(ii) Sensitive receiver stations (SR) near to key sensitive
receivers. (i.e. 7 impact stations).
(iii) Control / far field stations (CS) at representative
locations with less influence by the project (i.e 5 Control / far field
stations).
Control stations should be located, as far as practicable, both upstream and
downstream of the works area.
(iv) Stations for sensitivity test result (ST), which are
located close to the HKSAR boundary (i.e 3 sensitivity test stations).
(v) Not used.
(vi) Mf receiving pit are not required based on the
supporting documents for application for variation of environmental permit (EP
353/2009). Therefore, monitoring of nutrients and heavy metals of Mf Stations
are no longer required.
9.4.2 The co-ordinates of the proposed
monitoring stations during the construction phase are listed in Table 9.2. and shown in Figure 3.

The
ET of this Contract should conduct impact water quality monitoring at the station
listed in the table 9.2 as part of EM&A programme according to the latest
notification from ENPO when the monitoring station(s) is/are no longer covered
by another ET of the HZMB project. The ET of the Contract shall communicate and
share the monitoring data to the ET(s) of other works contracts if the water
quality monitoring station(s) is/are as part of EM&A programme.
9.4.3 Control stations (CS(Mf)3,
CS4, CS(Mf)5, CS6 and CSA[2])
are necessary
to compare the water quality from potentially impacted sites with the ambient
water quality. Control stations shall be located within the same body of water
as the impact monitoring stations but should be outside the area of influence
of the works and, as far as practicable, not affected by any other works. If
there are any changes on the monitoring location, that shall be submitted 4
weeks before commencement of baseline monitoring for EPD approval.
9.4.4 In-situ monitoring (DO, temperature,
turbidity, pH, salinity) and water sample for SS shall be taken at 3 water
depths, namely, 1 m below water surface, mid-depth and 1 m above sea bed,
except where the water depth is less than 6 m, in which case the mid-depth
station may be omitted. Should the water depth be less than 3 m, only the
mid-depth station will be monitored. The status and locations of water
sensitive receivers and the marine activities may change after issuing this
Manual. If such cases exist, the ET Leader shall propose with justification for
changes to monitoring locations or other requirements of the EM&A
programme, and seek approval from the IEC and EPD.
9.4.5 The ENPO may, depending on site
conditions and monitoring results, decides whether additional monitoring locations
shall be included or any monitoring locations could be removed / relocated
during any stage of the construction phase after getting approval from EPD.
9.5.1 Baseline conditions for marine water
quality shall be established and agreed with EPD prior to the commencement of
works. The purpose of the baseline monitoring is to establish ambient
conditions prior to the commencement of the works and to demonstrate the
suitability of the proposed impact and control monitoring stations. The
baseline conditions shall normally be established by measuring the DO,
temperature, turbidity, pH, salinity and SS at all designated locations. The
measurements shall be taken at all designated monitoring stations including
control stations, 3 days per week, at mid-flood (within ± 1.75 hour of the
predicted time) and mid-ebb (within ± 1.75 hour of the predicted time) tides,
for at least 4 weeks prior to the commencement of marine works.
Replicate in-situ measurements and samples collected from each independent
sampling event shall be collected to ensure a robust statistically
interpretable database.
9.5.2 Baseline monitoring
programme may overlap with other reclamation activities. The monitoring
exercise should be scheduled as far as possible to avoid concurrent dredging /
backfilling activities around the monitoring stations such that representative
ambient data could be sampled.
9.5.3 Other relevant data shall also be
recorded, such as monitoring location / position, time, water depth, tidal
stages, weather conditions and any special phenomena underway near the
monitoring station. There shall not be any marine construction activities in
the vicinity of the stations during the baseline monitoring.
9.5.4 Not applicable.
9.5.5 Baseline monitoring schedule
shall be faxed to EPD 2 weeks prior to the commencement of baseline monitoring.
The interval between two sets of monitoring shall not be less than 36 hours.

Reclamation
9.7.1A Impact monitoring for water quality shall be undertaken 3 days
per week, at mid-flood (within ± 1.75 hour of the predicted time) and mid-ebb
(within ± 1.75 hour of the predicted time) tides, with sampling / measurement
at the designated monitoring stations. Replicate in-situ measurements and
samples collected from each independent sampling event shall be collected to
ensure a robust statistically interpretable database. The interval between two
sets of monitoring shall 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. Two consecutive measures of DO concentration, DO
saturation, pH, salinity, temperature, turbidity and water samples for SS will
be taken in situ at 1 m below the surface, mid-depth and 1 m above the seabed
at each location. If the water depth is less than 6 m, the mid-depth
measurement may be omitted subject to the approval of the ER. If the depth is
less than 3 m, only the mid-depth measurements need to be taken subject to the
approval of the ER. The monitoring probes shall be retrieved out of water after
the first measurement and then redeployed for the second measurement. Where the
difference in value between the first and second readings of DO or turbidity
parameters is more than 25% of the value of the first reading, the reading
shall be discarded and further readings shall be taken.

9.8.1 Upon completion of all marine-based
construction activities, a post-project monitoring exercise on water quality
shall be carried out for 4 weeks in the same manner as the Baseline monitoring.
Replicate in-situ measurements and samples collected from each independent
sampling event shall be collected to ensure a robust statistically
interpretable database. The measurement parameters for Post-construction
monitoring shall include DO concentration and saturation, temperature,
turbidity, pH, salinity and SS. The measurement shall be taken at all
designated monitoring stations including control stations, 3 days per week, at
mid-flood (within ± 1.75 hour of the predicted time) and mid-ebb (within ± 1.75
hour of the predicted time) tides, for at least 4 weeks. Since the southern and
northern landfalls of TM-CLKL are distant from each other and based on the
tentative programme available during the EIA stage the two landfall has
different construction time frame, the Post-construction monitoring for each
landfalls may conducted separately. The ET should review the actual
implantation programme and recommend if a separate post-construction monitoring
for each landfall is required.

9.11.1 The
EIA Report has recommended construction and operational phase mitigation
measures. All the prepared mitigation measures are summarized in the EMIS as
shown in Appendix C.
10.1.1 The
EIA Report has assessed the ecological impacts caused by the construction
phase. Mitigation measures have been recommended in the EIA to ensure
compliance with the relevant legislative requirements. The mitigation measures
and ecological monitoring surveys are stated in this manual in the sections
below. A detailed ecological monitoring plan with specification and detailed
methodology will be prepared prior to the baseline monitoring, and submitted to
AFCD and EPD for approval.
Marine
Water Quality
10.2.1 Low
disturbance construction method: Any significant changes in water quality or
turbidity should be avoided. This
could be mitigated through construction methods. Silt curtains around the
marine works areas should be used.
10.2.2 Not
applicable.
10.2.3 Not
applicable.
10.2.4 Good
Site Practices: Effluent monitoring should be incorporated to make sure that
the discharged effluent from construction sites meets the relevant effluent
discharge guidelines.
10.2.5 Strict
enforcement on No-dumping – To avoid degrading the Chinese White Dolphin
Habitat, restrictions prohibiting dumping of rubbish, food, oil, or chemicals
will be strictly enforced.
10.2.6 Site
runoff control - For works on land, standard site runoff control measures will
be established and strictly enforced to ensure that discharge of contaminated
or silt- laden runoff into North Lantau waters is minimized.
10.2.7 Spill
response plan – In the event of vessels operating in the works areas transporting
oil or other hazardous chemicals, an oil-spill response plan, with specific
provisions for protection marine ecology and dolphins, will be formulated.
10.2.8 Not
applicable.
Terrestrial
Disturbance
10.2.9 The impact from this minor and short-term
source can be reduced by good site practices, including strictly following the
permitted works hours, using quieter machines where practicable, and avoiding
excessive lightings during night time.
Sedimentation
from Land-based Works Areas
10.2.10A Good
site practices (e.g., watering to reduce dust generation, prevention of
siltation of freshwater habitats) are recommended to be implemented. Site
runoff should be desilted, to reduce the potential for suspended sediments,
organics and other contaminants to enter existing streams and standing
freshwater
Marine
Noise and Disturbance
1)
Bored Piling
10.2.11 Not applicable.
10.2.12 Not applicable.
10.2.13 Not applicable.
2)A
Sheet Piling / Tubular Steel Piling
10.2.14A Vibratory piler for installation and removal of Tubular
Steel Piling – Tubular Steel Piling into the soft seabed sediment (i.e. not
requiring to drill onto rock surface) is required at the western edge of HKBCF
reclamation for construction and dismantling of temporary loading and unloading
point. To minimize the acoustic disturbance to Chinese White Dolphin (CWD), pile
piles will be driven by using vibratory piler, which is a type of silence
piling equipment and the noise generated is anticipated to be minimal.
10.2.15A Dolphin Exclusion Zone – dolphin exclusion zone of
250m radius should be implemented in the western edge of HKBCF reclamation for
installation and removal of Tubular Steel Piling. Works will be suspended when
any Chinese White Dolphin (CWD) is found within the exclusion zone..
3)A
Temporary Loading and unloading point and Works Vessels
10.2.16A Dolphin
Exclusion Zone – dolphin exclusion zone of 250m radius should be implemented at
the temporary loading and unloading point in the western edge of HKBCF
reclamation during the installation of the perimeter silt curtains and any
re-deployment of the perimeter silt curtains. Works will be suspended when any
Chinese White Dolphin (CWD) is found within the exclusion zone.
10.2.17 Dolphin Watching Plan - A dolphin
watching plan for works areas will also be included in the EM&A programme.
For the marine working sites, once the perimeter silt curtains are installed or
re-deployed, the marine works would be conducted inside the silt curtains and a
dolphin exclusion zone is not needed. Instead a dolphin watching plan will be
performed. The plan would include regular inspection of the silt curtains,
scanning of the waters surrounded by the curtains, and an action plan should be
devised to cope with any unpredicted incidents such as in case dolphins are
found within the waters surrounded by the silt curtains.
10.2.18 Acoustic decoupling of compressors
and other equipment – Air compressors and other noisy equipment that must be
mounted on construction vessels will be acoustically-decoupled to the greatest
extent feasible, for instance by using rubber air-filled tires.
Marine
Traffic
10.2.19 Vessel speed limit control – It is known that
fast-moving vessels are a threat to dolphins and porpoises, a speed limit of 10
knots will be strictly enforced within the working areas. This speed limit for vessels within the
boundaries of the Sha Chau/Lung Kwu Chau Marine Park appears to be effective in
protecting the dolphins from vessel collisions.
10.2.20 Skipper training – Captains of construction vessels working
in the West Lantau waters and near the Brothers Islands should undergo training
to learn about local dolphins and porpoises. They should be trained to be aware of
the protocol for “dolphin friendly” vessel operation (reference made to Code of
Conduct for Dolphin Watching Activities available from AFCD).
10.2.21 Predefined and regular routes for working vessels –
Captains of all working vessels should be required to use regular travel
routes, in order to minimize the chance of vessel collision. And the routes
would not go through the dolphin hotspot in Brothers Islands.
Road
Surface Runoff
10.2.22 Silt grease traps should be deployed to prevent a direct
input of road surface runoff to the marine water.
Chemical
Spillage
10.2.23 A Maritime Oil Spill Response Plan (MOSRP) has been
developed by Marine Department to deal with oil spill and their potential
hazard to the Hong Kong waters. The main objective of the MOSRP is to ensure a
timely and effective response to oil spillage and /or their potential treats in
the Hong Kong waters.
10.2.24 Similar to the Shenzhen Western Corridor project, a
contingency plan will be formulated to deal with the accidental event of the
serious spillage of oil or other harmful chemicals. A contingency plan in this
regard will be primarily for safety issues and water quality, but could also
help to safeguard the dolphin population. Following the example of Shenzhen Western Corridor, it
will be specified in the contingency plan that AFCD must be alerted by the Hong
Kong Police Force and Fire Services Department in case an accident of spillage
of chemical or oil is reported.
Precautionary/Enhancement
Measures
10.2.25 Not applicable.
10.2.26 Not applicable.
10.2.27 Not applicable.
10.3.1 An ecological monitoring
and audit programme would be needed for the Project. The monitoring programme
will include monitoring of physical parameters such as air, noise and water
quality, and ecological aspects such as CWD. The ecological monitoring and audit
programme will monitor potential impacts through construction activities, and
will verify the assessments which were made in the EIA report. The monitoring
includes the following tasks:
10.3.2A Vessel-based dolphin monitoring – A dolphin monitoring
programme at Northeast and Northwest Lantau , in particular the dolphin
sighting hotspots (e.g. Brothers Islands) and areas where juveniles have been
sighted, should be set up to verify the predictions of impacts and to ensure
that there are no unforeseen impacts on the dolphin population during
construction phase. The monitoring period should cover the pre-construction
phase (baseline conditions), the entire period of construction phase
(tentatively 2012 – 2016), and at least two years after the completion of construction
works .
10.3.3 Not applicable
10.3.4 Not

10.3.7 The ecological monitoring
surveys shall be undertaken by suitably qualified specialist(s), (i.e. dolphin
specialist), who shall have sufficient (at least 5-10 years) relevant
post-graduate experience and publication in the respective aspects and should
be independent of the construction contractor and should form part of the
independent ET. Approval on the specialist(s) responsible for ecological
monitoring survey shall be sought from AFCD and EPD..
10.4.1A The dolphin monitoring should adopt
line-transect vessel survey method, and cover the following line-transect
survey areas (Shown Figure 4) as in
AFCD annual marine mammal monitoring programme: �h

10.5.1 Baseline for dolphin monitoring
shall be established by two surveys per month in each survey area stated in
Section 10.4 for a period of three
months prior to the commencement of works and agreed with AFCD. The purpose of
the baseline monitoring is to establish pre-construction conditions prior to
the commencement of the works and to demonstrate the suitability of the
proposed monitoring method.
10.5.2 Not applicable
10.5.3 Not
applicable
10.5.4 Not
applicable
10.5.5 As
the project will last for a few years, the ET Leader should seek approval from
the IEC, AFCD and EPD on an appropriate methodology and parameters to be
recorded. A detailed ecological monitoring plan with specification and detailed
methodology for baseline monitoring will be prepared prior to the baseline
monitoring, and submitted to AFCD and EPD for approval.
10.6.1 Dolphin monitoring will be conducted twice a month in
each survey area stated in Section 10.4.1 throughout the entire construction
period.
10.6.2 Not applicable
10.6.3 Not
applicable
10.6.4A Should dolphin sighting numbers,
density or the distribution pattern in the construction or post construction be
significantly different (taking into account naturally occurring alterations to
distribution patterns such as due to seasonal change) to the pre-construction
baseline activity, the ET should inform AFCD and investigate the possible
causes of the change. Appropriate actions and a further monitoring should be
recommended and additional mitigation measures should be implemented as
necessary. Data should then be re-assessed and the need for any further
monitoring established. The monitoring results should be made available to EPD,
AFCD, ER and IEC within 2 weeks after the last survey day of the monitoring
month.
10.6.4B The data from impact monitoring should
be compared with the pre-construction baseline findings. Any apparent
differences in density among survey phases should be analysed for trends and
the statistical power of the analysis to detect effects of the desired size should
be tested. Statistical procedures shall be used for data comparison. A range of
applicable statistical procedures exist (e.g., t-test, ANOVA and ANCOVA, etc.)
and the ET shall propose the procedure to be applied as part of the impact and
post-construction dolphin monitoring programme design to be agreed with AFCD
prior to the monitoring being undertaken.
10.6.4C Comparison
of the impact and post-construction dolphin monitoring with that of over the
preconstruction baseline dolphin monitoring will allow the assessment of the
overall efficacy of the project-specific mitigation measures through the
implementation of an Event and Action Plan detailed in the Table 10.2.

10.7.1A Dolphin monitoring will be conducted twice a month in
each survey area stated in Section 10.4.1 after completion of construction.
10.8.1 The Action and Limit levels for Chinese White
Dolphin Monitoring are defined in Table 10.3(a) and 10.3(b). Should
non-compliance of the criteria occur, action in accordance with the Action Plan
in Table 10.2 shall be carried out.
10.8.2 An action plan has been
defined to indicate that should dolphin numbers be significantly different
(taking into account naturally occurring alterations to distribution patterns
such as due to seasonal change) to the baseline monitoring activity following the
impact and post-construction1 monitoring, the ET should
inform AFCD and investigate the possible causes of the change. Appropriate
actions and a further monitoring should be recommended and additional
mitigation measures should be implemented as necessary. Data should then be
re-assessed and the need for any further monitoring established. The action
plan should be undertaken within a period of 1 month after a significant
difference has been determined.
10.8.3 For the purpose of the
EM&A works, the “significance” level which will trigger the action plan
shall be proposed by the ET as part of the post-construction monitoring
programme1 design to be agreed with AFCD and EPD prior to the
monitoring being undertaken.

11 FISHERIES
11.1.1 The EIA report
identified and assessed the potential impacts
11.1.2 The water quality
monitoring and audit requirements are included in Section 9 Water Quality.
11.1.3 As mentioned in the EIA
report, no further monitoring and audit for fisheries are required.
12.1.1 The
marine archaeology investigation has concluded that there is no underwater
cultural heritage within the study area. No adverse impact on marine
archaeological is anticipated. Hence, further investigation or mitigation
measure is not required.
12.1.2 The
HKBCF is located in the waters to be north-east of the Airport. It would not
have any impacts on known built heritage and archaeological site. Mitigation
measure is not required for built heritage and terrestrial archaeology.
13.1.1 The HKBCF is a newly reclaimed site, it is anticipated
that blasting work will not be required during construction of the HKBCF.
Therefore no explosives QRA is required and hence no mitigation measure is
required.
14.1.1 The
EIA has recommended landscape and visual mitigation measures (refer to Section
14 of EIA Report) to be undertaken during both the construction and operation
phases of the project. This section outlines the monitoring and audit of these
measures.
14.2.1 The
design, implementation and maintenance of landscape mitigation measures should
be checked to ensure that any potential conflicts between the proposed
landscape measures and any other works of the project would be resolved as
early as practical without affecting the implementation of the mitigation
measures.

Detailed Design Phase
14.2.2 The
mitigation measures, which are proposed in the EIA to mitigate the landscape
and visual impacts, should be embodied into the detailed engineering design,
landscape design drawings and contract documents. The Detailed Design should be
checked to ensure that the measures are fully incorporated. Potential conflicts
with civil engineering, geotechnical, structural, lighting, signage, drainage
and underground utilities should resolved as early as practical.
14.2.3 The
following mitigation measures are proposed to avoid and reduce the identified
impacts.
l Minimize the footprint of
project and that the quantity of landscape character units and landscape
resources affected;
l Minimize temporary works
areas for construction works;
l Undertaking good site
practices by applying hydroseeding on temporary stockpiles and reclamation
areas;
l Conservation of topsoil for
reuse;
l Waste limitation by
recycling of felled trees into woodchip mulch for use in landscaped areas.
14.2.4 The
following design measures will be developed during detailed design stage to
remedy and compensate unavoidable impacts:
l Roadside planting and
planting along the edge of the reclamation is proposed;
l Transplanting of mature
trees in good health and amenity value where appropriate and reinstatement of
areas disturbed during construction by compensatory hydro-seeding and planting;
l Protection measures for the
trees to be retained during construction activities;
l Optimizing the sizes and
spacing of the bridge columns;
l Fine-tuning the location of
the bridge columns to avoid visually-sensitive locations;
l Not applicable as the
aesthetic design of the bridge is related to the HKLR Contract.
l Not applicable as the
decorative urban design is related to the HKLR Contract.
l Maximizing new tree, shrub
and other vegetation planting to compensate tree felled and vegetation removed;
l Providing planting area
around peripheral of HKBCF for tree planting screening effect;
l Providing salt-tolerant
native trees along the planter strip at affected seawall and newly reclaimed
coastline.
l Providing aesthetic
architectural design on the related buildings (e.g. similar materials for PCB
building facade to Airport buildings, roof planting and subtle materials for
other facilities buildings and so on), and the related infrastructure(e.g.
parapet planting and transparent cover for elevated footbridges) to provide
harmonious atmosphere of the HKBCF; and
l Fine-tuning the sizes of
the structural members to minimize the bulkiness of buildings and adjustment of
building arrangement to minimise disturbance to surrounding vegetation in the
HKBCF.
l Not applicable as the
aesthetic design on the viaduct, tunnel portals, at grade roads and reclamation
are related to the HKLR Contract.
14.2.5 The
following mitigation measures should be monitored during construction and
operation phases:

15.2.1 There
are contractual environmental protection and pollution control requirements as
well as environmental protection and pollution control laws in Hong Kong with
which construction activities must comply.
15.2.2 In
order that the works comply with the contractual requirements, all works method
statements submitted by the Contractor to the ER for approval shall be sent to
the ET Leader for vetting to ensure sufficient environmental protection and
pollution control measures have been included. The implementation schedule of
mitigation measures is summarized in Appendix
C.
15.2.3 The
ET Leader shall also review the progress and programme of the works to check
that relevant environmental laws have not been violated, and that any
foreseeable potential for violating laws can be prevented.
15.2.4 The
Contractor shall regularly copy relevant documents to the ET Leader so that
checking can be carried out. The document shall at least include the updated
Works Progress Reports, updated Works Programme, any application letters for
different licence / permits under the environmental protection laws, and copies
of all valid licences / permits.
The site diary and environmental records shall be made available for the
inspection by the relevant parties.
15.2.5 After
reviewing the document, the ET Leader shall advise the IEC and Contractor of
any non-compliance with contractual and legislative requirements on
environmental protection and pollution control for them to take follow-up
actions. If the ET Leader's review
concludes that the current status on licence / permit application and any
environmental protection and pollution control preparation works may result in
potential violation of environmental protection and pollution control
requirements, he shall also advise the Contractor and the ER accordingly.
15.2.6 Upon
receipt of the advice, the Contractor shall undertake immediate actions to
correct the situation. The ER shall follow up to ensure that appropriate action
has been taken in order to satisfy contractual and legal requirements.

complaint to determine its
validity, and assess whether the source of the problem is due to
works activities;
(iii) Identify
mitigation measures in consultation with the IEC if a complaint is valid and
due to works;
(iv) Advise
the Contractor if mitigation measures are required;
(v) Review
the Contractor's response to
identify mitigation measures, and
the updated situation;
(vi) If
the complaint is transferred from the EPD, submit interim report to the EPD on
status of the complaint investigation and follow-up action within the time
frame assigned by the EPD;
(vii) Undertake
