2.1.2
Potential air quality impact
from operation of the Project have also been assessed in accordance with the
EIA Study Brief requirements. No adverse
impact was anticipated during the operational phase of this Project.
Therefore, environmental monitoring and audit would not be required
during operational phase of the
Project.
2.1.3
This section presents the
requirements, methodology, equipment, monitoring locations, criteria and
protocols for the monitoring and audit of air quality impact during the
construction phase of the Project.
2.2
Construction Phase Dust
Monitoring
Monitoring Parameters
2.2.1
For regulatory purpose, the
concentration of particulate matters including 24-hour average Respirable
Suspended Particulates (RSP) concentrations and 24-hour average Fine Suspended
Particulate (FSP) concentrations are recommended to be monitored and audited at
the proposed monitoring locations during the construction phase. To ensure that any deteriorating air quality
could be readily detected and timely action could be undertaken, 1-hour average
RSP concentrations should also be monitored at the proposed monitoring
locations during the construction phase.
2.2.2
Monitoring and audit of the
abovementioned RSP and FSP concentrations shall be carried out by the ET. Should any deteriorating air quality be
detected, timely action shall be undertaken to rectify such situation.
Monitoring Equipment
2.2.3
The abovementioned parameters
should be monitored continuously by air sensor at monitoring stations specified
in Section 2.3. The air sensor to
be employed should meet the purpose of the monitoring which is 1-hour RSP,
24-hour RSP and 24-hour FSP concentrations in the ambient air. The air sensor should have a resolution of at
least 1 µg/m3, an accuracy of ± 10% to standard particles, equipped
with a shelter to protect the sensor and capable of operating continuously for
a 7 days period. It should be capable of detection of
PM10 and PM2.5, while size specification would be
optional subject to the environmental management strategy of the site. Particulates is
typically measured using an optical approach where light scattered by a
particle is used to estimate the particle mass concentration. The measurement range and detection limit of
the air sensor should be able to measure the full range of particulates
commonly found in the ambient, e.g. 0 – 1000 µg/m3. The accuracy of a sensor, in terms of
precision and bias, should also be evaluated during selection of air sensor,
according to the manufacturer’s specification, evaluation reports and published
literature. Whether the air sensor has
calibrated upon purchase, when and how collocation should be performed and how
to correct the measurement should be consulted with the sensor manufacturer and
fully understood before the air monitoring.
Other factors, such as response time, durability, enclosure, ease of
use, power supply, any data display, data transmission, data access, data
handling and cost should also be considered when selecting air sensor. Guidelines on the use of air sensor refer to The
Enhanced Air Sensor Guidebook 2022, USEPA, or for further technical
details at USEPA’s Air Sensor Toolbox website.
2.2.4
Generally, air sensors should
be placed at least 1.5 metres above ground and away from any obstruction,
vegetation or emission source which would interfere with the measurement. Other factors of the monitoring location,
such as security, availability of power supply, reliable communication
(cellular, Wi-Fi, etc.), should also be considered.
On-site Calibration and Quality Control
2.2.5
To ensure accuracy of the
measurement, monitoring equipment, including the air sensors, should be
calibrated regularly. The calibration should be conducted by collocating the
air sensor and a Transfer Standard (TS).
2.2.6
A TS is another particulate
matter (PM) monitor that is at least as capable as the air sensor to be
calibrated. Another sensor that has just
been calibrated may serve the purpose provided its performance is known to be
stable during the subsequent collocation period to be used as TS. Right before each on-site calibration, the TS
itself needs to be calibrated e.g. collocating with an PM reference monitor -
such as the Federal Reference Method (FRM) or the Federal Equivalent Method
(FEM) PM monitor at the accredited laboratories or research institutes - that
has been calibrated against traceable standard. The TS/reference monitor collocation should
last at least seven days.
2.2.7
The TS with known performance
characteristics will visit and collocate with each air sensor for
calibration. During collocation, the TS
should be placed near the subject sensor (<1 m if practicable) so that both devices
would be monitoring under the same environment, i.e. the same pollution sources
and weather conditions. The TS is then
turned on to warm-up for 30–60 minutes.
The collocation period starts after the warm-up and TS is then left
running with the subject sensor for at least three hours. The measurements from the sensor to be
calibrated and the TS during the collocation period will be statistically
analysed. The response of the sensor
should be adjusted if its performance during on-site calibration does not meet
the evaluation criteria as shown in Table 2.1.
·
Prepare a TS for PM monitoring, which has been
calibrated against a PM reference monitor (i.e. the FRM or FEM PM monitor).
·
The inlets of the TS and the subject sensor
shall be collocated at the same height with a horizontal separation distance of
<1 m.
·
Warm-up the transfer
standard on-site for
30-60 minutes.
·
Collocated monitoring shall be conducted in a
continuous period to collect at least 180 valid minute average measurements.
The valid data rate shall be at least 80% during the collocation period.
·
The collected minute average measurement results
should be statistically analysed using the two-tier
approach as presented in Table
2.1.

2.2.10
The collocated monitoring of TS
and each air sensor on the field should be carried out every month. If a sensor
failed in 2 or 3 consecutive collocated monitoring, the sensor should be
checked or maintained to improve its performance, or it should be replaced.
Wind Data Monitoring Equipment
2.2.11
Wind data monitoring equipment
should also be provided and set up at conspicuous locations for logging wind
speed and wind direction near to the dust monitoring locations. The equipment installation location should be
proposed by the ET and agreed with the PMR in consultation with the IEC. For installation and operation of wind data
monitoring equipment, the following points should be observed:
·
the wind sensors should
be installed on masts at an elevated level 10m above ground so that they are
clear of obstructions or turbulence caused by the buildings;
·
the wind data should be captured by a data
logger. The data recorded in the data
logger should be downloaded periodically for analysis at least once a month;
·
the wind data monitoring equipment should be
re-calibrated at least once every six months; and
·
wind direction should be divided into 16 sectors
of 22.5 degrees each.
2.2.12
In exceptional situations, the
ET may propose alternative methods to obtain representative wind data upon
approval from the PMR and agreement from the IEC.
Construction Dust
Monitoring Plan
2.2.13
Before commencing the air
monitoring, the ET should formulate a construction dust monitoring plan with
air sensor and submit to IEC to seek their feedback and consent. The plan should be aligned with the EM&A
Manual and verified by IEC. The plan
should include but not limited to the followings:
·
Details on the pollutants and environmental
parameters to be monitored;
·
Describe the equipment and measurement method to
be used;
·
Address the criteria for placing air sensors;
·
Discuss the monitoring locations selected and rationale;
·
Describe the criteria for selecting air sensors
and test to determine if they are working properly;
·
Determine the collocation location and establish
the calibration and/or collocation and data correction methods;
·
Identify types of data that may be used in the
data analysis, including nearby reference monitor data, weather data, etc. for monitoring;
·
List the procedures to maintain and operate air
sensors, including site visits, routine maintenance, emergency maintenance,
daily data review, periodic collocations, etc.;
·
Describe the QC procedures to be performed;
·
Describe how the data are processed, stored and adjusted;
·
Describe the ownership of the data and who is
granted access to it;
·
Describe how the air monitoring data to be
managed, tracing the path of data generation in the field to the final data use
and end storage;
·
Describe the procedures to verify and validate
data during collection period;
·
Describe the methods to produce meaningful
figures and visualization; and
·
Describe how the monitoring results will be
used.
2.2.14
The ET is responsible for the
provision of the monitoring equipment and should provide sufficient
number of air sensors for the field work and TS for carrying out
continuous on-site monitoring and ad-hoc monitoring or collocation.
2.2.15
If the ET proposes alternative
dust monitoring equipment / methodology after the approval of this Manual,
agreement from the IEC and EPD should be sought. The instrument should also be calibrated
regularly following the requirements specified by the equipment
manufacturers.
2.3.1
The selected construction dust
monitoring stations are air sensitive receivers located in the vicinity of
construction sites and covered different wind directions to capture the
potential worst-case impact from the construction of the Project. The proposed construction dust monitoring
stations during construction phase are listed in Table 2.2 and are illustrated in Figure 2.1 to Figure
2.3. The
ET should agree with IEC on the position of the air sensor for
installation. The considerations for the
positioning of air sensor refer to
Section 2.3.4, the
air monitoring plan with sensors and the feedbacks
from IEC.

any stage of the construction phase.
Impact Monitoring
2.3.6
During construction phase of
the Project, the ET shall carry out continuous impact monitoring in terms of
1-hour average RSP concentration, 24-hour rolling average RSP concentration and
24-hour rolling average FSP concentration, with air sensors throughout the
construction phase of the Project at the designed construction dust monitoring
stations when there are project-related construction activities being
undertaken within a radius of 500m from the construction dust monitoring
stations.
Event and Action Plan
2.3.7
The
ET shall compare the impact monitoring results with air quality criteria set up
for 1-hour and 24h-hour average RSP and 24-hour average FSP. Table 2.3 shows the air quality criteria,
namely Action and Limit levels, to be used.
However, the Action and Limit
Levels may subject to changes based on the prevailing AQOs implemented at the
time of the impact monitoring.

2.4.1
Mitigation measures for
construction phase air quality impact have been recommended in the EIA
Report. All the recommended mitigation
measures and designs are detailed in the implementation schedule as presented
in Appendix B. The Contractor should be responsible for the
design and implementation of these measures.
2.5.1
Regular site inspection and
audit at least once per week should be conducted during the entire construction
phase of the Project to ensure the recommended mitigation measures are properly
implemented.
3.1.1
The EIA has considered the
potential noise impacts associated with the construction and operational phases
of the Project.
3.1.2
Construction noise mitigation
measures would be required to reduce noise levels to the stipulated
standard. A Construction Noise
Management Plan (CNMP) is required to be submitted to the Director of the
Environmental Protection (DEP) before tender invitation. The Contractor is required to undertake those
mitigation measures in CNMP and implement properly.
3.1.3
Since no adverse road traffic
noise impact is anticipated from the Project under unmitigated scenario, no
road traffic noise monitoring is considered necessary during operational phase.
3.1.4
No fixed plant noise sources
are proposed to be operated under the current design of the Project. However, in the event that
any planned fixed noise sources are proposed under the detailed design stage, a
Fixed Noise Source Management Plan (FNMP) is required and will be submitted to
the DEP before commencement of construction of the Project. The Contractor should fully implement those
recommended mitigation measures and requirements as specified in the FNMP.
3.1.5
In this section, the
requirements, methodology, equipment, monitoring locations, criteria and
protocols for the monitoring and audit of noise impacts during construction
phase of the Project are presented.
Construction Phase
3.2.1
No adverse
construction noise impact is anticipated with the
implementation of mitigation measures such as good site practices, use of
quality powered mechanical equipment (QPME) and construction method, use of
temporary noise barriers and noise enclosures to screen noise from relatively
static PMEs, etc. Recommended mitigation
measures and good site practices are summarised in Appendix B.
3.2.2
The Contractor shall also be
required to prepare an updated CNMP with reference to Section 8 and Annex 21 of
the EIAO-TM as well as Section 4.5.5 of the EIA Report and this EM&A
Manual. In case there is any change to
the construction noise mitigation measures recommended in the CNMP, the
Contractor shall submit an updated CNMP one month before the implementation of
such change, including an implementation schedule clearly out the mitigation
measures, the implementation party, location and timing of implementation.
Operational Phase – Road Traffic Noise
3.2.3
In accordance with HyD's guidance notes on road surface requirements, standard
road surfacing materials, which also serve as low noise road surfacing (LNRS),
would be applied to road sections of new road projects with design speed of 80
km/hr or above. Such surfacing materials
provide a noise reduction performance of approximate 2.5dB(A) as compared with
concrete paving. It was confirmed with HyD that LNRS would be applied to the road segments of TYLL
with 80 km/hr or above under unmitigated scenario.
Operational Phase – Fixed Noise Source
3.2.4
As mentioned, no fixed plant
noise sources are proposed to be operated under the current design of the
Project. However, in
the event that any planned fixed noise sources are proposed under the
detailed design stage, the Project Proponent shall submit a Fixed Noise Sources
Management Plan (FNMP) before tender invitation and before commencement of
implementation of the Project. The FNMP
should contain a quantitative fixed noise sources impact assessment covering
the noise impact from existing, committed and planned fixed noise sources on
existing, committed and planned NSRs.
The FNMP should also include an inventory of noise sources, design
measures including noise mitigation measures of these noise sources,
implementation schedule of mitigation measures with implementation party and
timing, and fixed noise sources commissioning test plan. The pre-tender FNMP should be included in the
relevant tender document. The FNMP shall
be prepared and checked by Certified Noise Modelling Professional as recognized
by the HKIQEP or equivalent. The FNMP
shall be certified by the ET Leader and verified by the IEC as conforming to
the relevant information and recommendations of the approved EIA report.
3.2.5
The key steps for quantitative
fixed noise sources noise assessment are summarized as follows.
· Identify the proposed planned fixed noise sources;
· Identify/update representative NSRs that may
be affected by the proposed noise sources;
· Conduct background noise measurement at
representative NSRs to determine the noise criteria for both daytime and nighttime;
· Use standard acoustic principle for
attenuation and directivity;
· Adopt correction of tonality, impulsiveness
and intermittency as stipulated in Technical Memorandum for the Assessment
of Noise from Places other than Domestic Premises, Public Places or
Construction Sites (IND–TM);
· Calculate the noise impacts using the latest
or the most updated plant inventories and utilisation
schedule, if available; and
· Calculate cumulative fixed plant noise
impacts, if any.
3.2.6
Mitigation measures recommended
and requirement specified in the FNMP shall be fully implemented by the
Contactor.
Monitoring
Parameters
3.3.1
The construction noise levels
should be measured in terms of the 30-minute A-weighted equivalent continuous
sound pressure level (Leq(30-min)). Leq(30-min)
should be used as the monitoring parameter for the time
period between 0700 and 1900 hours on normal weekdays. If construction works are extended to include
works during the hours of 1900 - 0700, and/or percussive piling is be carried
out, applicable permits under NCO shall be obtained by the Contractor. The monitoring requirements and conditions
stipulated in the permits have to be followed.
3.3.2
Supplementary information for
data auditing and statistical results such as L10 and L90
should also be obtained for reference.
Sample noise field data sheet is shown in Appendix C1 of this Manual for
reference. The ET Leader may modify the
data record sheet for this EM&A programme but the format of which should be
agreed by the IEC.
Monitoring Equipment
3.3.3
As referred to the Technical
Memorandum (TM) issued under the Noise Control Ordinance (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 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 shall be accepted as valid only
if the calibration level from before and after the noise measurement agree to
within 1.0 dB.
3.3.4
Noise measurements shall be
made in accordance with standard acoustic principles and practices in relation
to weather conditions. The wind speed
shall be checked with a portable wind speed meter capable of measuring the wind
speed in m/s.
3.3.5
The ET is responsible for the
provision of the monitoring equipment.
The ET shall ensure that sufficient noise measuring equipment and
associated instrumentation are available for carrying out regular impact
monitoring and ad hoc monitoring. All
the equipment and associated instrumentation shall be clearly labelled. The equipment installation location shall be
proposed by the ET Leader and agreed with the PMR and EPD in consultation with
IEC.
Monitoring Locations
3.3.6
Based on the findings of the
EIA Report, the designated locations for construction noise monitoring are
listed in Table
3.1 and shown in Figure 3.1.

3.3.7
The status and locations of
NSRs may change after issuing this Manual.
If such cases exist, the ET shall propose updated monitoring locations
and seek approval from the PMR and IEC and agreement from EPD on the proposal.
3.3.8
When alternative monitoring
locations are proposed, the monitoring locations shall be chosen based on the
following criteria:
i. at locations close to the major site activities which are likely to
have noise impacts;
ii. close to the most affected existing NSRs; and
iii. for monitoring locations located in the vicinity of the sensitive
receivers, care shall be taken to cause minimal disturbance to the occupants
during monitoring.
3.3.9
The construction noise
monitoring station shall normally be at a point 1 m from the exterior of the
sensitive receivers building façade and be a position 1.2 m above the
ground. If there is a problem with
access to the normal monitoring position, an alternative position shall 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 positions.
Baseline Monitoring
3.3.10
Given that there would be
various concurrent projects near the existing NSRs such as Route 11 and
HKIW-NEL Link, baseline monitoring in the absence of construction activities
would not be feasible. In addition, the Action
and Limit Levels of construction noise monitoring (Table
3.2 refers) are not based on the baseline noise environment and thus
baseline monitoring is considered not necessary.
Impact Monitoring for Construction Noise
3.3.11
Construction noise monitoring
should be carried out at the designated monitoring station when there are
Project-related construction activities being undertaken within a radius of 300
m from the monitoring stations. The
monitoring frequency should depend on the scale of the construction
activities. An initial guide on the
monitoring is to obtain one set of 30-minute measurement at each station
between 0700 and 1900 hours on normal weekdays at a frequency of once a week
when construction activities are underway.
3.3.12
If construction works are
extended to include works during the hours of 1900 - 0700, and/or percussive
piling is be carried out, applicable permits under NCO shall be obtained by the
Contractor. The monitoring requirements
and conditions stipulated in the permits have to be
followed.

Road Traffic Noise
3.4.1
Based on the assessment results,
mitigation measures would not be required for all identified representative
NSRs. Therefore, EM&A for road
traffic noise during operational phase of the Project is not considered
required.
Fixed Noise Sources
3.4.2
No fixed noise sources would be
proposed under the Project, therefore EM&A for fixed noise sources is not
considered required.
3.5.1
Regular site environmental
audit during the construction phase of the Project should be conducted at least
once per week to ensure proper implementation of mitigation measures and good
site practices as listed in Appendix B
and the noise control requirements stated in EPD’s "Recommended
Pollution Control Clauses for Construction Contracts” to further minimize
the potential noise nuisance during construction phase.
4.1.1
In accordance with the
recommendations of the EIA, mitigation measures have been proposed during the
construction phase of the Project to ensure that unacceptable water quality
impacts do not occur at the nearby Water Sensitive Receivers (WSRs) as a result of the construction works. Weekly site inspection and audit will also be
conducted to ensure that the recommended mitigation measures recommended in the
EIA Report are properly implemented during the construction stage. Details of the mitigation measures are
presented in Section 5 of the EIA Report.
Relevant mitigation measures are presented in Appendix B.
4.1.2
In addition to the recommended
mitigation measures, water quality monitoring should be undertaken during the
construction phase of the Project to ensure that all the recommended mitigation
measures are properly implemented. As no
adverse water quality impact from the operation of the Project is anticipated,
no monitoring or audit is required during the operational phase. Appropriate remedial actions should be taken
in case the environmental performance criteria are exceeded. Detailed monitoring requirements as presented
in the following sections.
4.2.1
Water quality parameters are
chosen for monitoring with consideration of the potential water quality impacts
from the construction of the Project (i.e. release of polluted water with high
suspended solids (SS) load from the construction works). This would ensure the potential impacts from
construction activities of the Project can be readily detected and timely
action could be undertaken to rectify the situation. Water quality parameters to be measured are
shown in Table 4.1. Dissolved oxygen (DO),
dissolved oxygen saturation (DO%), temperature, turbidity, salinity, pH and
suspended solids (SS) should be monitored at designated marine water quality
monitoring stations during the marine works of the Project.
4.2.2
All parameters should be
measured in-situ whereas SS should be determined by the laboratory. DO should be presented in mg/L and in %
saturation. Replicate in-situ
measurements and samples collected from each independent sampling event shall
be collected to ensure a robust statistically interpretable database.
4.2.3
Other relevant data shall also
be recorded, including monitoring location / position, time, water depth, tidal
stages, weather conditions and any special phenomena or work activities
undertaken around the monitoring and works area that may influence the monitoring
results. Sample data record sheets for
marine water and inland water are shown in Appendices C2
and C3, respectively, for reference.

4.3.1
For water quality monitoring,
the following equipment should be supplied and used by the environmental
contractor.
Dissolved Oxygen and Temperature Measuring Equipment
4.3.2
The instrument should be a
portable, weatherproof measuring instrument complete with cable, sensor,
comprehensive operation manuals, and should be operable from a DC power
source. It should be capable of
measuring dissolved oxygen levels in the range of 0 - 20 mg/L and 0 - 200%
saturation and a temperature of 0 - 45 °C.
4.3.3
It should have a membrane
electrode with automatic temperature compensation complete with a cable of not
less than 35m in length. Sufficient
stocks of spare electrodes and cable should be available for replacement where
necessary.
4.3.4
Should salinity compensation
not be built-in in the DO equipment, in-situ salinity shall be measured
to calibrate the DO equipment prior to each DO measurement.
Salinity Measuring Equipment
4.3.5
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 monitoring location.
Turbidity Measuring Equipment
4.3.6
Turbidity should be measured in-situ
by the nephelometric method using an instrument that is portable and
weatherproof using a DC power source with cable, sensor, and comprehensive
operation manuals. This instrument
should have a photoelectric sensor capable of measuring turbidity between 0 -
1000 NTU (e.g. Hach model 2100P or other approved instrument of similar
type). The meter should be calibrated in order to establish the relationship between NTU units and
the levels of SS. The turbidity
measurement should be carried out on a split water sample from the same water
sample collected for suspended solids analysis.
pH Measuring Instrument
4.3.7
The instrument shall consist of
a potentiometer, a glass electrode, a reference electrode and a
temperature-compensating device. It
shall be readable to 0.1 pH in a range of 0 to 14. Standard buffer solutions of at least pH 7
and pH 10 shall be used for calibration of the instrument before and after
use. Details of the method shall comply
with American Public Health Association (APHA), 19th ed. 4500-HTB or equivalent
methods subject to approval of EPD.
Positioning Device
4.3.8
A hand-held Global Positioning
System (GPS) with way point bearing indication or other equivalent instrument
of similar accuracy will be provided and used during monitoring to ensure the
monitoring team is at the correct location before taking measurements.
Water Depth Detector
4.3.9
A portable, battery-operated
echo sounder will be used for the determination of water depth at each
designated monitoring station.
Water Sampling Equipment
4.3.10
A water sampler, consisting of
a transparent PVC or glass cylinder of at least 500mL, which can be effectively
sealed with latex cups at both ends, should be used (Kahlsico
Water Sampler 13SWB203 or an approved similar instrument). The sampler shall 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. Water samples for SS measurements should be
contained in high density polyethene bottles.
Back-up Equipment
4.3.11
Sufficient stocks of spare
parts should be maintained for replacements when necessary. Back-up monitoring equipment should also be
available so that monitoring can proceed uninterrupted even when some equipment
is under maintenance, calibration, etc.
Sampling/Testing Protocols
4.3.12
All in-situ monitoring
instruments should be checked, calibrated and certified by a laboratory
accredited under HOKLAS or any other international accreditation scheme before
use, and subsequently re-calibrated at 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.
4.3.13
For on-site calibration of
field equipment, the “Guide to Field and On-Site Test Methods for the
Analysis of Waters” (BS 1427:1993) should be observed. Sufficient stocks of spare parts should be
maintained for replacements when necessary.
Backup monitoring equipment should also be made available so that
monitoring can proceed uninterrupted even when some equipment is under
maintenance, calibration, etc.
4.3.14
Water samples for SS
measurements should be collected in high density polythene bottles, packed in
ice (cooled to 4
°C without being frozen), and delivered to a HOKLAS
laboratory as soon as possible after collection.
4.3.15
Three replicate samples should
be collected from each of the monitoring events for in-situ measurement
and lab analysis. It is recommended to
take three replicates at each sampling station from each independent sampling
event for all parameters in order to ensure a robust
statistically interpretable data set.
Laboratory Analysis
4.3.16
All laboratory work should be
carried out in a HOKLAS accredited laboratory or other international accredited
laboratory. Water samples of about
1,000mL should be collected at the monitoring and control stations for carrying
out the laboratory determination. The
detection limit shall be 0.5 mg/L or better.
The determination work should start within 24 hours after collection of
the water samples. The SS laboratory
measurements should be provided within 2 days of the sampling event (48
hours). The analyses should follow the
standard methods as described in APHA Standard Methods for the Examination of
Water and Wastewater (APHA 2540D for SS), 21st Edition, or
equivalent methods subject to approval of EPD.
4.3.17
The submitted information
should include pre-treatment procedures, instrument use, Quality
Assurance/Quality Control (QA/QC) details (such as blank, spike recovery,
number of duplicate samples per batch etc.), detection limits and accuracy. The QA/QC details should be in accordance
with requirements of HOKLAS or another internationally accredited scheme. QA/QC result shall be reported. EPD may also request the laboratory to carry
out analysis of known standards provided by EPD for quality assurance. Additional duplicate samples may be required
by EPD for inter laboratory calibration.
Remaining samples after analysis shall be kept by the laboratory for 3
months in case repeat analysis is required.
If in-house or non-standard methods are proposed, details of the
method verification may also be required to submit to EPD. In any circumstance,
the sample testing shall have comprehensive quality assurance and quality
control programmes. The laboratory shall
prepare to demonstrate the programmes to EPD or his representatives when
requested.
4.4.1
Total 13 water monitoring
stations including 9 marine water (C1 to C3, M1 to M5 and
M7) and 4 inland water (C4, M6, M8 and M9) have been established to identify potential water quality impacts to
nearby WSRs.
Locations of the monitoring stations are shown in Figure 4.1 with the
coordinates presented in Table 4.2.
The monitoring stations located away from the construction works area
will serve as control stations to obtain ambient water quality conditions. Meanwhile, impact
stations situated near the works area will be used to compare the water quality
of potentially impacted sites with the ambient water quality.
4.4.2
The monitoring stations
proposed in this section are indicative subject to further review before
commencement of the water quality monitoring works. The status and locations of water quality monitoring stations and
the works activities may change after issuing this Manual. For such occasion, the
ET Leader shall propose with justification for changes to monitoring locations
or other requirements of the EM&A programme, taking into
account the following considerations and seek approval from the IEC and
EPD:
·
close to the sensitive
receivers which are directly or likely to be affected;
·
for monitoring locations
located in the vicinity of the sensitive receivers, care shall be taken to
cause minimal disturbance during monitoring; and
·
two or more control stations
which shall be at locations representative of the project site in its
undisturbed condition. Control stations shall be located, as far as is
practicable, both upstream and downstream of the works area.

4.4.3
Baseline, impact and
post-construction monitoring shall be conducted. The following requirements
should be followed for baseline, impact and post-construction monitoring:
·
Measurement should be taken at
3 water depths, namely, 1m below water surface, mid-depth and 1m above seabed,
except where the water depth less that 6m, the mid-depth station may be
omitted. Should the water depth be less
than 3m, only the mid-depth station will be monitored. The ET should agree with EPD on all the
monitoring stations;
·
Duplicate in-situ measurements
and water samples collected from each independent monitoring event are required
for all parameters to ensure a robust statistically interpretable dataset;
·
No sampling should be carried
out when typhoon signal No. 3 or above or black rainstorm signal is hoisted;
and
·
At each measurement depth, two
consecutive measurements would be taken. The probes would be retrieved out of
the water after the first measurement and then redeployed for the second
measurement. When the difference in
value between the first and second measurement of on-site parameters is more
than 25% of the value of the first reading, the reading shall be discarded and further readings shall be taken.
Baseline Monitoring
4.4.5
Baseline monitoring should be
undertaken three times per week, at mid-flood and mid-ebb tides, for at least
four weeks at the designated stations prior to the commencement of the
construction works. The interval between
two consecutive sets of monitoring should not be less than 36 hours. Baseline monitoring schedule prepared by the
ET should be submitted to the PMR, the IEC and EPD two weeks prior to the
commencement of baseline monitoring.
4.4.6
There shall not be any
construction activities in the vicinity of the monitoring stations during the
baseline monitoring. In exceptional
cases when insufficient baseline monitoring data or questionable results are obtained,
the ET Leader shall seek approval from the IEC and EPD on an appropriate set of
data to be used as baseline reference.
Impact Monitoring
4.4.7
The purpose of impact
monitoring is to ensure the suitability of the recommended mitigation
measures. Impact monitoring should be
undertaken three times per week, at mid-flood and mid-ebb tides, during
the course of construction works. The
interval between two consecutive sets of monitoring should not be less than 36
hours except when there are exceedances of Action and/or Limit Level, in which
case monitoring frequency should be increased.
The proposed water quality monitoring schedule prepared by the ET should
be submitted to the PMR, the IEC and EPD at least two weeks before the first
day of the monitoring month. The PMR,
the IEC and EPD should be notified immediately of any changes in schedule.
4.4.8
If the impact monitoring data
collected at the impact monitoring stations indicate that the Action or Limit
levels as shown in Table 4.3 are
exceeded, analysis should be conducted to identify whether the exceedance is
caused by Project activities. If the
data analysis results indicate that the exceedance is caused by this Project,
appropriate actions including lowering the working rate, or rescheduling of
works should be taken and additional mitigation measures should be implemented
as necessary.
Post-construction Monitoring
4.4.9
Post-construction monitoring
will comprise sampling on three days a week, at mid-flood and mid-ebb tides,
for four weeks after completion of the construction works. The monitoring requirements will be the same
as the impact monitoring stated in Section
4.4.7
above. Post project monitoring schedule
prepared by the ET should be submitted to the PMR, the IEC and EPD at least two
weeks before the first day of the post project monitoring month. The PMR, the IEC and EPD should be notified
immediately of any changes in schedule.
4.5.1
Water quality monitoring
results will be evaluated against Action and Limit Levels shown in Table 4.3.

Notes:
[1] For SS and
turbidity, non-compliance of the water quality limits occurs when monitoring
result is higher than the limits.
[2] For DO,
non-compliance of the water quality limits occurs when the monitoring result is
lower than the limits.
4.5.2
Should the monitoring results
of the water quality parameters at any designated monitoring stations indicate
that the water quality criteria are exceeded, the actions in accordance with
the Event and Action Plan in Table 4.4
should be carried out.
4.5.3
In addition to monitoring,
regular environmental site audit is required to ensure the proper
implementation of good site practices, construction runoff pollution preventive
measures, drainage and sewage control measures.

Waste Management
5.1.1
Potential waste management
implication arising from the construction and operational phases of the Project
were addressed in the EIA Report. Waste
management during construction phase will mainly be the contractor’s
responsibility to ensure that any wastes produced during the construction and
demolition works are handled, stored and disposed of in accordance with good
waste management practices and relevant EPD’s regulations and other legislative
requirements. The Contractor shall
implement the reuse and recycling measures addressed in the EIA Report.
5.1.2
Large quantities of wastes are
not expected from the operation of the Project and no adverse environmental
impacts would arise with the implementation of good waste management
practices. EM&A would not be necessary
during the operational phase.
5.2.1
Appendix B
provides the implementation schedule of the recommended mitigation measures
during both construction and operational phases.
Construction Phase
5.2.2
Mitigation measures for waste
management recommended in the EIA Report should form the basis of the site
Waste Management Plan (WMP) to be developed by the Contractor in the
construction stage. A WMP, as a part of
the Environmental Management Plan (EMP), should be prepared in accordance with ETWB
TC (W) No.19/2005 and submitted to the PMR for approval. The monitoring and auditing requirement
stated in ETWB TC (W) No.19/2005 should be followed with
regard to the management of C&D materials.
Operational Phase
5.2.3
Wastes produced during
operational phase would mainly comprise of floating refuse and chemical
waste. With the implementation of the
recommended mitigation measures for handling, transportation and disposal of
the identified waste arisings, no adverse impacts are anticipated during
operational phase of the Project. Therefore, no other specific waste monitoring
during operational phase is required.
5.2.4
With the appropriate handling,
storage and removal of waste arisings during the construction and operation of
the Project as presented in Appendix B,
the potential to cause adverse environmental impacts would be minimized. During the site inspections, the ET shall pay
special attention to the issues relating to waste management and check whether
the Contractor has implemented the recommended good site practices, waste
reduction measures and other mitigation measures.
5.3
Audit Requirement
Construction Phase
5.3.1
Regular audits and site
inspections should be carried out during construction phase by the PMR, ET and Contractor
to ensure that the recommended good site practices and the recommended
mitigation measures listed in Appendix B
are properly implemented by the Contractor.
The audits should concern all aspects of on-site waste management
practices including waste generation, storage, recycling, transport and
disposal. Apart from site inspection,
documents including licences, permits, disposal and recycling records should be
reviewed and audited for compliance with the legislation and contract
requirements.
5.3.2
The requirements of the
environmental audit programme are set out in Section 12 of this Manual. The audit programme will verify the
implementation status and evaluate the effectiveness of the mitigation
measures.
Operational Phase
5.3.3
As it is anticipated that there
would not be any insurmountable impacts during the operational phase,
monitoring and audit requirements are not required.
6.1.1
Based on the site appraisal, three
potentially contaminated sites (i.e. Public Carpark and
Adjacent Vegetated Land (Site STW1), Dockyard (Site HUD1) and Sai Tso Wan Concrete
Batching Plant (Site HUD2)) were identified with potential land contamination
concerns to the Project. However, owning
to the site constraints, it is
considered not feasible to carry out the site investigation (SI) works under
the EIA Study within the three potentially contaminated sites. Moreover, there is an existing Vacant Land
(Site LT2) which was inaccessible at the time of site walkover. Based on the tentative construction programme,
land clearance / resumption for the Project would not commence until 2026, there could be
changes in the operation or land uses within the three potentially contaminated sites and the
inaccessible site which may cause further contamination issues. Further site appraisal should be carried out within the Proposed Clearance Limit and off-site facilities / works areas at a later stage of the Project to confirm / update
the land uses / activities and to identify the presence of on-site and off-site potential
contamination sources. In addition, should there be any expansion of the Proposed
Clearance Limit, further site appraisal would also be required to be carried
out within the expanded area. Contamination
Assessment Plan(s) (CAP(s)), which present
the findings
of the further site appraisal, the latest site conditions of the concerned
sites and updated sampling strategy and testing protocol, should be submitted
to EPD for approval.
6.1.2
The further site
appraisal and submission of CAP(s) should be carried out prior to the
commencement of the SI works. The SI
works should be carried out according to EPD’s approved CAP(s). Following the completion of SI works and
receipt of laboratory test results, Contamination Assessment Report(s) (CAR(s))
should be prepared to present the findings of the SI works and to discuss the
presence, nature and extent of contamination.
If contamination is identified, Remediation Action Plan(s) (RAP(s)) which provides
details of the remedial actions for the identified contaminated soil and / or
groundwater should be endorsed by EPD. The remedial
actions should be formulated with consideration given
to the Source-Pathway-Receptor Paradigm
by adopting the appropriate control method(s) (i.e. source control method,
pathway control method and/or receptor control method). To minimise
the cost of remediation work, if remediation is required and where appropriate,
“pathway control” approach, e.g. by proper capping the source of contamination
by soil or concrete slabs or by the use of membranes
or solidification, would be considered to prevent migration of contaminants.
6.1.3
Remediation
action, if necessary, will be carried out according to EPD endorsed RAP(s) and
Remediation Report(s) (RR(s)) will be submitted after completion of the
remediation action. The RR(s) should be
endorsed by EPD prior to the commencement of construction works at the
respective identified contaminated areas (if any). The submission of CAP(s), associated SI works
and any necessary remediation should be carried out prior to the commencement
of construction works.
6.2
Construction Phase
6.2.1
Remediation works, if
necessary, would be carried out based on the recommended further works outlined
in the EIA report. Mitigation measures
for the remediation works, if necessary, as recommended in the EIA Report, Appendix B of this Manual and future
RAP(s) should be implemented during the remediation works. EM&A should be carried out in the form of
regular monthly site inspection during construction phase to ensure the
recommended mitigation measures are properly implemented and findings of the
audit should be reported in the EM&A reports.
6.3.1
As any contaminated soil /
groundwater would be identified and properly remediated prior to the
commencement of any construction works at the concerned facilities / areas,
land contamination during the operational phase is not expected. As such, environmental monitoring and audit
during operational phase for land contamination is considered not necessary.
7.1.1
Potential ecological impacts
arising from the construction and operational phases of the Project were
assessed in the EIA Report. Mitigation measures have been recommended to
minimize the potential direct and indirect impacts to natural habitats, as well
as the associated wildlife. With the
full implementation of the above recommended avoidance, minimisation and
compensatory mitigation measures, no significant residual ecological impact is
anticipated from the Project.
Nonetheless, EM&A is considered necessary
and the requirements are described below.
7.2.1
The implementation of
mitigation measures recommended in the EIA Report to minimize potential
ecological impacts are provided in Appendix
B.
Construction Phase
7.2.3
Furthermore,
specific mitigation measures in addressing potential impacts to flora,
amphibian, freshwater fauna, and coral species of conservation importance would
be implemented, which include pre-construction surveys for flora, amphibian,
freshwater fauna and coral species of conservation importance in permanent and
temporary works areas, as well as in affected watercourses (i.e. W1, W2 and W3)
and their downstream sections. If deemed
necessary (i.e. where direct impact on identified individuals is identified),
in-situ preservation, transplantation and/or compensatory planting of flora of
conservation importance, translocation of colonies of coral species of
conservation importance and translocation of amphibian or other identified
freshwater fauna of conservation importance would take place. Monitoring and site auditing of plant
preservation, transplantation and/or compensatory planting efforts for flora
and coral species of conservation importance would be carried out, the details
of which would be provided in a transplantation proposal and/or compensatory
planting proposal, where applicable, for AFCD’s agreement and approval. Likewise, monitoring and site auditing of
translocation efforts for amphibian, or other
identified freshwater fauna of conservation importance would also be carried
out, the details of which would be provided in a translocation proposal for
AFCD’s agreement and approval.
7.2.4
Regular
site auditing for construction works around affected watercourses W2 and W3
would be carried out to ensure best management of
construction site run-off and discharge and mitigation measures are properly
implemented, in order to effectively mitigate impacts arising from site run-off and discharge
as well as secondary indirect water quality impact on amphibian,
or other identified freshwater fauna of conservation importance inhabiting
downstream.
7.2.5
The
monitoring requirements are stated in Section 7.3 below, while the
requirements of environmental audit and reporting are provided in Sections
12 and 13 of this Manual.
Operational Phase
7.2.6
No
significant ecological impact is anticipated during the operational phase of the Project, as such
no ecological monitoring and auditing during operational phase is required.
Preservation, Transplantation and/or Compensatory Planting
of Flora Species of Conservation Importance
7.3.2
During the pre-construction
detailed vegetation survey, each identified individuals should be tagged and
mapped, with photographs and information including their height, diameter at
breast height, spread, condition, form, amenity value, survival of
transplantation and proposed treatment etc.
Prior to the commencement of transplantation, a Plant Preservation and Transplantation Proposal should be prepared and submitted to AFCD for
approval. The proposal shall include the
findings of the pre-construction detailed vegetation survey, the proposed
methodologies of plant preservation, transplantation and compensation,
identification of suitable receptor site, implementation programme,
post-transplantation monitoring and maintenance programme including monitoring
frequency, monitoring parameters, and recommended remedial measures. Mitigation approach
in the order of in-situ preservation, transplantation, and compensation would
be followed. In the case where some directly affected individuals of
Small Persimmon were deemed infeasible for preservation or transplantation,
legitimate justifications shall be provided.
Compensatory planting of the species could be considered and
implemented. The compensation ratio of
affected individuals should be in the ratio of 1:1, unless agreed otherwise
with AFCD. The recommended compensation
planting quantity, planting location, planting methodologies as well as
provision of a post-planting monitoring programme should be included in the Plant Preservation and Transplantation Proposal. A
planting proposal shall be prepared for agreement with AFCD containing
information on the recommended planting quantity, planting location, planting
methodologies as well as provision of a post-planting monitoring programme.
Translocation of Romer’s Tree Frog and Other Identified
Aquatic/Water-dependent Species of Conservation Importance
7.3.3
A
pre-construction survey should be carried out by a qualified ecologist(s) in
the at-grade works area where direct impact would be anticipated in order to identify the presence of any individuals of
Romer’s Tree Frog or any other aquatic/water-dependent
species of conservation importance (inc. amphibians and freshwater fauna). Greater caution should be paid to affected
watercourses (i.e. W1, W2 and W3) and its adjacent riparian shrubland /
grassland habitats. The scope and
methodology of the pre-construction survey, and the curriculum vitae of the
qualified ecologist(s) should be submitted and agreed with AFCD prior to
commencement of survey works. In
instances where individuals are identified in the works area and translocation
is required, the methodology and findings of the pre-construction survey, along
with a translocation and post-translocation monitoring plan presenting the
number of individuals to be translocated, the translocation methodology, the
identified translocation site, the implementation schedule, as well as
post-translocation monitoring methodology and programme should be defined and
presented in a Translocation Proposal, which shall be submitted to AFCD for
comments and approval prior to translocation works. Individuals should be translocated to nearby
habitats of similar habitat conditions, adequate barriers such as hoarding and
fencing should be set up around the works area following translocation to
prevent individuals from entering the works area. The potential translocation recipient site
should be located well outside the areas where direct and indirect impacts from
the construction works of the project (i.e. W5 and W6), as well as those of
other planned/committed projects nearby, are not expected.
Translocation of Affected Coral Colonies
7.3.4
A
pre-construction detailed coral survey shall be conducted in the marine works
area prior to the commencement of marine works by a qualified coral
ecologist(s) with SCUBA diving qualification and experience, the curriculum
vitae of whom shall be submitted to AFCD along with the scope and methodology
of the detailed coral survey for review and agreement prior to commencement of
the survey. The survey should confirm specifically the number, the species and the location of
coral colonies to be directly affected by the construction of the
pile-supported VIPS, the reclamation and associated dredging works. Identified coral colonies should be numbered,
sized, photographed, mapped and tagged in the survey. An assessment of the suitability of
translocation for each identified coral colony should be presented in the coral
translocation plan, along with the proposed recipient site, translocation
methodology and programme, monitoring methodology and programme for the
translocation coral colonies. The
potential translocation recipient site should possess a coral colony
composition similar to that of the existing site and
should be located well outside areas where direct and indirect impacts from the
marine works of the project, as well as of other planned/committed projects
nearby, are not expected. The findings
of the detailed coral survey and the proposed treatment for the identified
coral colonies should be reported in the Coral Translocation Proposal and
submitted to AFCD for approval prior to commencement of the translocation
works.

species of conservation importance i.e. Romer’s Tree Frog and Caridina serrata were recorded in the
downstream sections of watercourses W2 and W3, where construction works will
take place in the upper tributaries.
During the construction of at-grade roads, viaduct supports, tunnel
portals and associated slope works at watercourses W1, W2 and W3, temporary
stream diversion should be carried out to retain waterflow downstream and to
avoid construction materials from entering the watercourse and affecting the
fauna inhabiting the sections downstream, including Romer’s Tree Frog and Caridina serrata.
7.3.7
Regular
site audits should be carried out to ensure best management of construction
site run-off and discharge and mitigation measures proposed for reducing
construction site run-off and discharge are being implemented with stringent
adherence to relevant guidelines stipulated in the ProPECC
PN 2/23 Construction Site Drainage (EPD, 2023) and ETWB TC(W) No. 5/2005
Protection of Natural Streams/Rivers from Adverse Impacts Arising from
Construction Works (ETWB, 2005).
General Site Audit and Inspection for Natural Habitats and
Construction Disturbances
7.3.8
Site audit and inspection will
be undertaken during the construction phase to ensure that the mitigation
measures (Appendix B refers) are
properly implemented, and all aboveground works areas do not encroach
beyond the works area boundaries. Site audit and inspections should be
carried out at least once per week throughout the construction phase by ET. The areas of
inspection shall not be limited to the environmental situation, pollution
control and mitigation measures within the works area; it should also review
the environmental situation outside the works area which is likely to be affected, directly or indirectly, by the
site activities (Section 12 refers).
In case of non-compliance, the Contractor should be informed to
strengthen the proposed mitigation measures accordingly.
7.3.9
All temporarily affected areas
should be reinstated to their existing conditions as far as practicable after
completion of the works. Areas where
excavation of soil is required for the site formation, installation and
construction of viaduct supports, retaining wall and anchorage shall be
refilled and re-vegetated. Hydroseeding
and/or planting of plant species found in the original habitat should be
prioritised to maximise and achieve a reinstated condition that resembles the
original habitat condition as close as possible. Reinstatement works/programme should be
proposed by the Contractor (e.g. reinstatement planting and associated
monitoring on the affected area), in consultation with relevant authorities
(e.g. AFCD and EPD) where appropriate.
Enhancement Opportunities on
Seawall and Marine Structures
7.3.10
Several strategies could be
integrated into the design of future coastal structures, such as seawalls on
the reclaimed land for TYLL anchorages and towers, as well as surfaces and
supporting structures on the pile-supported VIPS. Following the confirmation of the final
layout and design of these structures, a detailed Eco-shoreline Design
Proposal shall be prepared and submitted to AFCD for agreement and
approval. This proposal must include a comprehensive Ecological Monitoring
Plan to establish a practical and feasible program for assessing the
effectiveness of the design. The plan will detail the proposed monitoring
methodologies, such as the use of standard marine ecological survey techniques,
and define the performance parameters to be tracked. These parameters may
include species diversity and abundance, recruitment rates of benthic
organisms, and the health of key habitat-forming species, all of which will be
proposed for AFCD's approval. The monitoring shall commence following the
establishment of the eco-shoreline and the proposed monitoring period and frequency shall be agreed upon with AFCD. A key component of the plan will be an
adaptive management framework, which requires establishing clear performance
criteria (i.e., action and limit levels). If monitoring reveals that these
criteria are not being met, an investigation into the causes will be required,
followed by the submission of a remedial action proposal to AFCD for approval.
All monitoring and assessment work shall be conducted by qualified marine
biologists with a minimum of five years of experience in marine organism
identification and ecological restoration
8.
FISHERIES
8.1.1
The EIA Report concluded that
potential fisheries impact due to construction and operation of the Project are
considered minor. Specific mitigation measures for fisheries are not required.
Nevertheless, potential fisheries resources would be affected by indirect water
quality impact which would be controlled by construction site best practices.
Hence, no adverse fisheries impact is anticipated during both construction and
operational phases.
8.2.1
No
fisheries-specific mitigation measures would
be required during both construction and operational phases. Mitigation measures recommended in the water
quality impact assessment will also minimise any adverse impacts on fisheries,
including silt curtain which will be provided during the construction phase
around the reclamation extent. Other
recommended practices for other potential sources of water quality impacts
during the construction phase should also be implemented where applicable.
8.3.1
As
no unacceptable adverse impacts have been predicted to occur during both the
construction and operational phase of the Project, fisheries monitoring is not
considered necessary. Site inspections
with focus on water quality during construction phase should be carried out to
monitor any malpractice leading to deterioration of water quality of the
surrounding which may in turn affect the fisheries sensitive receivers (i.e. a monitoring and audit programme aims to ensure that the released
suspended solid concentrations from reclamation filling and stockpiling
activities, also acts as a protection against impacts to fisheries sensitive
receivers). Water quality monitoring
should be undertaken between the project area and the Ma Wan Fish Culture Zone
throughout the entire construction period, to monitor the water quality and
avoid deterioration of water quality nearby.
As there are no anticipated adverse fisheries impacts during operational
phase, environmental monitoring and audit requirements are not required.
9.1.1
The EIA Report has recommended
landscape and visual mitigation measures to be undertaken during both the construction and operational phases of the Project. This section
defines the audit requirements to confirm the recommended landscape and visual
impact mitigation measures are effectively implemented.
9.2
Mitigation Measures
9.2.1
The landscape and visual mitigation measures during construction and
operational phases as recommended in the EIA Report are summarised in Appendix B. The proposed mitigation measures should be incorporated in the
detailed landscape and engineering design.
9.2.2
The construction phase
mitigation measures should be adopted from the commencement of construction and
should be in place throughout the entire construction period. Mitigation measures for the operational phase
should be adopted during the detailed design and be built as part of the
construction works so that they are in place on commissioning of the Project.
9.2.3
Any potential conflicts among
the proposed mitigation measures in terms of design, implementation and
maintenance, and the Project works, and operational requirements should also be
identified and resolved at early as practicable without affecting the implementation
of the mitigation measures. Any changes to the mitigation measures should be
incorporated in the detailed engineering and landscape design drawings and the
Landscape and Visual Mitigation Plan.
9.3.1
All mitigation measures
proposed in the EIA and implemented by the Contractor should be audited by a
Registered Landscape Architect (RLA), as a member of the Environmental Team
(ET), on a regular basis to ensure compliance with the intended aims of the measures.
9.3.2
Regular site audits should be
undertaken during the construction phase and the 12-month establishment period
(operational phase) to check that the proposed landscape and visual mitigation
measures are properly implemented and maintained as per their intended
objectives. The RLA shall audit the
implementation of landscape construction works particularly during site
clearance operations when the proposed tree felling and transplanting will take
place and subsequent tree maintenance operations and planting works.
9.3.3
Site inspections should be
undertaken by the ET at least once every month during the construction period,
and once every two months for the 12-month establishment period during
operational phase.
9.3.4
The implementation of landscape
construction works and subsequent maintenance during the 12-month establishment
period must be supervised by RLA.
10.1.1
One (1) declared monument (Tang
Lung Chau Lighthouse) and four (4) other identified items (namely Abandoned House
close to the Tang Lung Chau Lighthouse, Small Structure closed to Tang
Lung Chau Lighthouse, Old Pier at Tang Lung Chau West, and the Inscribed
Stone Pillar at Yi Chuen are identified within the 300m assessment area of the
Project.
10.1.2
No direct or indirect impacts
are anticipated to the declared monument (Tang Lung Chau Lighthouse) and the four (4) other identified items (Abandoned House close to
the Tang Lung Chau Lighthouse, small structure close to Tang Lung Chau, Old
pier at Tang Lung Chau West, and inscribed stone of Yi Chuen) during the
construction and operational stages.
10.1.3
No Site of Archaeological
Interests (SAIs) is situated within the assessment area. Hence, no impact is
anticipated on any SAIs during the construction and operational phases.
10.1.4
Diver survey was undertaken
from 28 September to 4 October 2024 upon the issuance of Licence to Excavate
and Search for Antiquities. None of the
thirty-three (33) targets are considered of archaeological interest and no
further investigations are therefore considered necessary. Besides, the
systematic diver survey to the south of Ma Wan did not identify any features
with archaeological potential. Hence, no
impact on marine archaeology is anticipated from the Project during the
construction and operational phases.
10.2.1
The mitigation measures on
cultural heritage recommended in the EIA Report are summarized as below. The implementation of the mitigation measures
provided in Appendix B.
Construction
Phase - Built Heritage and Other Identified Items
10.2.2
No direct or indirect impact is
anticipated on the built heritage and other identified items. Therefore, no mitigation measure would be
required.
Construction Phase – Terrestrial and Marine
Archaeology
10.2.3
No impact on terrestrial and
marine archaeologies is anticipated from the Project during the construction
phase and no mitigation measures are therefore required. As a precautionary measure and pursuant to the
Antiquities and Monuments Ordinance (Cap. 53), the
project proponent is required to inform AMO immediately
in case of discovery of antiquities or supposed antiquities in the course of
works, so that appropriate mitigation measures, if needed, can be timely
formulated and implemented in agreement with and
to the satisfaction of AMO.
Operational
Phase
10.2.4
No impact on built heritage,
terrestrial and marine archaeologies would be anticipated from the Project
during the operational phase. Therefore,
no mitigation measure would be required for cultural heritage during the
operational phase.
Construction
Phase
10.3.1
No EM&A requirement would
be required for the identified declared monument (Tang Lung Chau Lighthouse)
and the
four (4) other identified items (the Abandoned House and
Small Structure close to the Tang Lung Chau Lighthouse, the Old Pier at Tang
Lung Chau West, and the Inscribed Stone of Yi Chuen) during the construction
phase.
10.3.2
No EM&A requirement would
be required for both terrestrial and marine archaeologies during the
construction phase.
10.3.3
Notwithstanding, as a
precautionary measure and pursuant to the Antiquities and Monuments Ordinance
(Cap. 53), the
project proponent is required to inform AMO immediately
in case of discovery of antiquities or supposed antiquities in the course of
works, so that appropriate mitigation measures, if needed, can be timely
formulated and implemented in agreement with and to the satisfaction of AMO.
Operational
Phase
10.3.4
No EM&A requirement would
be required for cultural heritage during the operational phase.
11.2.1
Good safety practices are
recommended to further manage and minimize the potential risks during
construction phases of the Project. They
are summarized in the Implementation Schedule provided in Appendix B.
11.3.1
The EIA study concluded that
both individual and societal risk comply with the Hong Kong Risk Guidelines as
stipulated in Annex 4 of the EIAO-TM. No
environmental monitoring and audit requirements would be required.
12.1.1
Site inspection provides a
direct means to trigger and enforce specified environmental protection and
pollution control measures. These shall
be undertaken regularly and routinely to inspect construction activities in order to ensure that appropriate environmental protection
and pollution control mitigation measures are properly implemented. The site inspection is one of the most
effective tools to enforce the environmental protection requirements at the
works area.
12.1.2
The ET Leader shall be
responsible for formulating the environmental site inspection, the deficiency
and remedial action reporting system, and for carrying out the site inspection
works. The ET Leader shall submit a
proposal for site inspection and deficiency and remedial action reporting
procedures to the Contractor for agreement, and to the PMR for approval. The ET’s proposal for rectification would be
made known to the IEC.
12.1.3
Regular site inspections shall
be carried out at least once per week. The areas of inspection shall not be
limited to the environmental situation, pollution control and mitigation
measures within the site; it should also review the environmental situation
outside the works area which is likely to be affected,
directly or indirectly, by the site activities.
The ET shall make reference to the following
information in conducting the inspection:
·
the EIA and EM&A recommendations on
environmental protection and pollution control mitigation measures;
·
ongoing results of the EM&A program;
·
works progress and programme;
·
individual works methodology proposals (which
shall include proposal on associated pollution control measures);
·
contract specifications on environmental
protection and pollution prevention control;
·
relevant environmental protection and pollution
control laws/legislations; and
·
previous site inspection results undertaken by the ET and others.
12.1.4
The Contractor shall keep the PMR
and ET Leader updated with all relevant environmental related information on
the construction contract necessary for him to carry out the site
inspections. Inspection results and
associated recommendations for improvements to the environmental protection and
pollution control works shall be recorded and submitted to the IEC and the
Contractor within 24 hours for reference and for taking immediate remedial
action. The Contractor shall follow the
procedures and time-frame stipulated in the
environmental site inspection, and the deficiency and remedial action reporting
system formulated by the ET Leader, to report on any remedial measures subsequent to the site inspections.
12.1.5
The PMR, ET and the Contractor
shall also carry out ad-hoc site inspections if significant environmental
problems are identified. Inspections may
also be required subsequent to receipt of an
environmental complaint, or as part of the investigation work, as specified in
the Event and Action Plans for environmental monitoring and audit.
12.2.1
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.
12.2.2
In order that the works are in compliance with the contractual requirements, all
works method statements submitted by the Contractor to the PMR for approval
shall be sent to the ET Leader for vetting to see whether sufficient
environmental protection and pollution control measures have been included. The implementation schedule of mitigation
measures is summarized in Appendix B.
12.2.3
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.
12.2.4
The Contractor shall regularly
copy relevant documents to the ET Leader so that works checking could be
carried out effectively. 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 shall also be available for
the ET Leader's inspection upon his request.
12.2.5
After reviewing the
documentation, the ET Leader shall advise the 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 accordingly.
12.2.6
Upon receipt of the advice, the
Contractor shall undertake immediate action to remedy the situation. The PMR and ET shall follow up to ensure that
appropriate action has been taken in order to satisfy
contractual and legal requirements.
12.3.1
Complaints shall be referred to
the ET Leader for action. The ET Leader shall undertake the following
procedures upon receipt of any complaint:
i. log complaint and date of receipt onto the complaint database and
inform the IEC immediately;
ii. investigate the 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;

proposed mitigation measures for landscape and visual issues after the first
operation year of the Project. The final
EM&A report for operational phase should contain at least the following
information:
i. executive summary (1 - 2 pages):
ii. drawings showing the Project Area, any environmental sensitive
receivers and the locations of the monitoring and/or control stations;
iii. basic project information including a synopsis of the project
organisation, contacts of key management, and a synopsis of work undertaken during the course of the project or past twelve months;
iv. a brief summary of
EM&A requirements including environmental mitigation measures for operation
stage as recommended in the project EIA Report;:
v. a summary of the implementation status of environmental protection
and pollution control / mitigation measures for operation stage, as recommended
in the project EIA Report and summarised in the updated implementation schedule;
vi. a summary record of all complaints received (written or verbal) for
