The “Expansion of Hong Kong
International Airport into a Three-Runway System” (the Project) serves to meet
the future air traffic demands at Hong Kong International Airport (HKIA). On 7
November 2014, the Environmental Impact Assessment (EIA) Report (Register No.:
AEIAR-185/2014) for the Project was approved and an Environmental Permit (EP)
(Permit No.: EP-489/2014) was issued for the construction and operation of the
Project.
Airport Authority Hong Kong
(AAHK) commissioned Mott MacDonald Hong Kong Limited (MMHK) to undertake the
role of Environmental Team (ET) for carrying out the Environmental Monitoring
& Audit (EM&A) works during the construction phase of the Project in

reporting period from 1 to 30 November 2019.
Key Activities in the Reporting
Period
The key
activities of the Project carried out in the reporting period included
reclamation works and land-side works. Reclamation works included deep cement
mixing (DCM) works, marine filling, and seawall construction. Land-side works
involved mainly airfield works, foundation and substructure work for Terminal 2
expansion, modification and tunnel work for Automated People Mover (APM) and
Baggage Handling System (BHS), and preparation work for utilities, with
activities include site establishment, site office construction, road and
drainage works, cable ducting, demolition, piling, and excavation works.

Environmental auditing works,
including weekly site inspections of construction works conducted by the ET and
bi-weekly site inspections conducted by the Independent Environmental Checker
(IEC), audit of SkyPier High Speed Ferries (HSF), audit of construction and
associated vessels, and audit of implementation of Marine Mammal Watching Plan
(MMWP) and Dolphin Exclusion Zone (DEZ) Plan, were conducted in the reporting
period. Based on information including ET’s observations, records of Maritime
Surveillance System (MSS), and contractors’ site records, it is noted that
environmental pollution control and mitigation measures were properly
implemented and construction activities of the Project in the reporting period
did not introduce adverse impacts to the sensitive receivers.

Results of Impact
Monitoring
The monitoring works for
construction dust, construction noise, water quality, construction waste, landscape & visual, and CWD were conducted during
the reporting period in accordance with the Manual.
Monitoring results of
construction dust, construction noise, construction waste, and CWD did not
trigger the corresponding Action and Limit Levels in the reporting
period.
The water quality monitoring
results for dissolved oxygen (DO), turbidity, total alkalinity, chromium and
nickel obtained during the reporting period were within the corresponding
Action and Limit Levels stipulated in the EM&A programme. Relevant
investigation and follow-up actions will be conducted according to the EM&A
programme if the corresponding Action and Limit Levels are triggered. For
suspended solids (SS), one testing result triggered the relevant Action Level,
and the corresponding investigation was conducted accordingly. The
investigation findings concluded that the case was not related to the Project.
To conclude, the construction activities in the reporting period did not
introduce adverse impact to all water quality sensitive receivers.

Methodology
2.3.1
Measuring Procedure
The measurement procedures involved in the impact air
quality monitoring can be summarised as follows:
a. The portable direct reading dust meter
was mounted on a tripod at a height of 1.2m above the ground.
b. Prior to the measurement, the
equipment was set up for 1 minute span check and 6 second background check.
c. The one hour dust measurement was
started. Site conditions and dust sources at the nearby area were recorded on a
record sheet.
d. When the measurement completed, the
“Count” reading per hour was recorded for result calculation.
2.3.2
Maintenance and Calibration
The
portable direct reading dust meter is calibrated every year against high volume
sampler (HVS) to check the validity and accuracy of the results measured by
direct reading method. The calibration record of the HVS provided in Appendix E
of the Construction Phase Monthly EM&A Report No. 46, and the calibration
certificates of portable direct reading dust meters
listed in Table 2.3
are valid in the reporting period.

Monitoring
Equipment
Noise monitoring was performed
using sound level meter at each designated monitoring station. The sound
level meters deployed comply with the International Electrotechnical Commission
Publications 651:1979 (Type 1) and 804:1985 (Type 1) specifications. Acoustic
calibrator was used to check the sound level meters by a known sound pressure
level for field measurement. Details of equipment used in the reporting
period are given in Table 3.3.

Monitoring
Methodology
3.3.1
Monitoring Procedure
The monitoring procedures involved in the noise monitoring
can be summarised as follows:
a. The sound level meter was set on a tripod at
least a height of 1.2m above the ground for free-field measurements at
monitoring stations NM1A, NM4, NM5 and NM6. A correction of +3dB(A) was applied
to the free field measurements.
b. Façade measurements were made at the
monitoring station NM3A.
c. Parameters such as frequency weighting,
time weighting and measurement time were set.
d. Prior to and after each noise measurement,
the meter was calibrated using the acoustic calibrator. If the difference
in the calibration level before and after measurement was more than 1dB(A), the
measurement would be considered invalid and repeat of noise measurement would
be required after re-calibration or repair of the equipment.
e. During the monitoring period, Leq,
L10 and L90 were recorded. In addition, site
conditions and noise sources were recorded on a record sheet.
f. Noise measurement results were
corrected with reference to the baseline monitoring levels.
g. Observations were recorded when high
intrusive noise (e.g. dog barking, helicopter noise) was observed during the
monitoring.
3.3.2
Maintenance and Calibration
The maintenance and calibration procedures are summarised
below:
a. The microphone head of the sound level meter
was cleaned with soft cloth at regular intervals.
b. The meter and calibrator were sent to the
supplier or laboratory accredited under Hong Kong Laboratory Accreditation
Scheme (HOKLAS) to check and calibrate at yearly intervals.
Calibration
certificates of the sound level meters and acoustic calibrators used in the
noise monitoring listed in Table 3.3
are valid in the reporting period.
3.4
Summary of Monitoring Results
The noise monitoring schedule involved in
the reporting period is provided in Appendix B.
The noise monitoring results in
the reporting period are summarised in Table 3.4. Detailed
impact monitoring results are presented in Appendix C.

examination took place during this reporting period.
No complaints were received from
any sensitive receiver that triggered the Action Level. All monitoring results
were also within the corresponding Limit Levels at all monitoring stations in
the reporting period.
3.5
Conclusion
As the construction activities were far away from the monitoring stations, major sources of noise dominating the monitoring stations observed during the construction noise impact monitoring were traffic noise near NM1A and aircraft noise near NM6 during this reporting period. It is considered that the monitoring work during the reporting period was effective and there was no adverse impact attributable to the Project activities.

Water Quality Monitoring
Water
quality monitoring of DO, pH, temperature, salinity, turbidity, suspended
solids (SS), total alkalinity, chromium, and nickel was conducted three days
per week, at mid-ebb and mid-flood tides, at a total of 23 water quality
monitoring stations, comprising 12 impact (IM) stations, 8 sensitive receiver
(SR) stations and 3 control (C) stations in the vicinity of water quality
sensitive receivers around the airport island in accordance with the Manual. The purpose of water quality monitoring at the IM stations
is to promptly capture any potential water quality impact from the Project
before it could become apparent at sensitive receivers (represented by the SR
stations). Table 4.1
describes the details of the monitoring stations. Figure 4.1 shows the locations of the
monitoring stations.

Notes:
(1)
With the operation of HKBCF, water quality monitoring at SR1A station
was commenced on 25 October 2018. To better reflect the water quality in the
immediate vicinity of the intake, the monitoring location of SR1A has been
shifted closer to the intake starting from 5 January 2019.
(2)
Details of selection criteria for the two
heavy metals for regular DCM monitoring refer to the Detailed Plan on Deep
Cement Mixing available on the dedicated 3RS website (http://env.threerunwaysystem.com/en/ep-submissions.html). DCM specific water quality monitoring parameters
(total alkalinity and heavy metals) were only conducted at C1 to C3, SR2, and
IM1 to IM12.
(3)
According to the Baseline
Water Quality Monitoring Report, C3 station is not adequately representative as
a control station of impact/ SR stations during the flood tide. The control
reference has been changed from C3 to SR2 from 1 September 2016 onwards.
(4)
Total alkalinity and heavy
metals results are collected at SR2 as a control station for regular DCM
monitoring.
(5)
As the access to SR6 was
obstructed by the construction activities and temporary structures for Tung
Chung New Town Extension, the monitoring location has been relocated to SR6A
starting from 8 August 2019.
(6) The monitoring location for SR8 is subject to
further changes due to silt curtain arrangements and the progressive relocation
of this seawater intake.
4.1
Action and Limit Levels
In accordance with the Manual,
baseline water quality levels at the above-mentioned representative water
quality monitoring stations were established as presented in the Baseline Water
Quality Monitoring Report. The
Action and Limit Levels of general water quality monitoring and regular DCM
monitoring stipulated in the EM&A programme for triggering the relevant
investigation and follow-up procedures under the programme are provided in Table 4.2.

Monitoring
Methodology
4.3.1
Measuring Procedure
Water
quality monitoring samples were taken at three depths (at 1m below surface, at
mid-depth, and at 1m above bottom) for locations with water depth >6m. For
locations with water depth between 3m and 6m, water samples were taken at two
depths (surface and bottom). For locations with water depth <3m, only the mid-depth
was taken. Duplicate water samples were taken and analysed.
The water samples for all
monitoring parameters were collected, stored, preserved and analysed
according to the Standard Methods, APHA 22nd ed. and/or other
methods as agreed by the EPD. In-situ measurements at monitoring locations
including temperature, pH, DO, turbidity, salinity, alkalinity and water depth
were collected by equipment listed in Table 4.4 and Table 4.5.
Water samples for heavy metals and SS analysis were stored in high density
polythene bottles with no preservative added, packed in ice (cooled to 4ºC
without being frozen), delivered to the laboratory within 24 hours of
collection.
4.3.2
Maintenance and Calibration
Calibration of In-situ Instruments
Wet bulb calibration for a DO meter
was carried out before commencement of monitoring and after completion of all
measurements each day. Calibration was not conducted at each monitoring
location as daily calibration is adequate for the type of DO meter employed. A
zero check in distilled water was performed with the turbidity probe at least
once per monitoring day. The probe was then calibrated with a solution of known
NTU. In addition, the turbidity probe was calibrated at least twice per month
to establish the relationship between turbidity readings (in NTU) and levels of
SS (in mg/L). Accuracy check of the digital titrator was performed at
least once per monitoring day.
Calibration certificates of the
monitoring equipment used in the reporting period listed in Table 4.4
are still valid.
4.3.3
Laboratory
Measurement / Analysis
Analysis of
SS and heavy metals have been carried out by a HOKLAS accredited laboratory,
ALS Technichem (HK) Pty Ltd (Reg. No. HOKLAS 066). Sufficient water samples
were collected at all the monitoring stations for carrying out the laboratory
SS and heavy metals determination. The SS and heavy metals determination works
were started within 24 hours after collection of the water samples. The
analysis of SS and heavy metals have followed the standard methods summarised
in Table 4.6.
The QA/QC procedures for laboratory measurement/ analysis of SS and heavy
metals were presented in Appendix F of the Construction Phase Monthly EM&A
Report No.8.

Summary of Monitoring Results
The water quality monitoring schedule for the reporting period
is updated and provided in Appendix B.
The water quality
monitoring results for DO, turbidity, total alkalinity, nickel, and chromium
obtained during the reporting period were within their corresponding Action and
Limit Level. The detailed
monitoring results are presented in Appendix C.
For SS, one of
the testing results triggered the corresponding Action Level, and investigation
was conducted accordingly.

4.5
Conclusion
During the reporting period, it
is noted that the vast majority of monitoring results were within their
corresponding Action and Limit Levels, while only one result triggered the
corresponding Action Level, and investigation was conducted accordingly.
Based on the investigation
findings, the result that triggered the corresponding Action Level was not due
to the Project. Therefore, the Project did not cause adverse impact at the
water quality sensitive receivers. All required actions under the Event and
Action Plan were followed. The case appeared to be due to natural fluctuation
or other sources not related to the Project.
Nevertheless, as part of the
EM&A programme, the construction methods and mitigation measures for water
quality will continue to be monitored and opportunities for further enhancement
will continue to be explored and implemented where possible, to strive for
better protection of water quality and the marine environment.
In the meantime, the contractors were reminded to implement and maintain all mitigation measures during weekly site inspection and regular environmental management meetings. These include maintaining mitigation measures properly for reclamation works including DCM works, marine filling, and seawall construction as recommended in the Manual.

Waste Management
In accordance with the Manual,
the waste generated from construction activities was audited once per week to
determine if wastes are being managed in accordance with the Waste Management
Plan (WMP) prepared for the Project, contract-specific WMP, and any statutory
and contractual requirements. All aspects of waste management including waste
generation, storage, transportation and disposal were assessed during the
audits.

Weekly monitoring on all works
contracts were carried out by the ET to check and monitor the implementation of
proper waste management practices during the construction phase.
Recommendations made included
provision and maintenance of proper chemical waste storage area, as well as
handling, segregation, and regular disposal of general refuse. The contractors
had taken actions to implement the recommended measures.
Based on updated information
provided by contractors, construction waste generated in the reporting period
is summarised in Table 5.2.
There were no complaints,
non-compliance of the WMP, contract-specific WMPs, statutory and contractual
requirements that triggered Action and Limit Levels in the reporting period.

Chinese White Dolphin Monitoring
In
accordance with the Manual, CWD monitoring by small vessel line-transect
survey supplemented by land-based theodolite tracking survey and passive
acoustic monitoring should be conducted during construction phase.
The small vessel line-transect
survey should be conducted at a frequency of two full surveys per month, while
land-based theodolite tracking survey should be conducted at a frequency of one
day per month per station at Sha Chau (SC) and Lung Kwu Chau (LKC) during the
construction phase as stipulated in the Manual. Supplemental theodolite
tracking survey of one additional day has also been conducted at LKC, i.e. in
total twice per month at the LKC station.
6.1
Action and Limit Levels
The Action and Limit Levels for
CWD monitoring were formulated by the action response approach using the
running quarterly dolphin encounter rates STG and ANI derived from the baseline
monitoring data, as presented in the CWD Baseline Monitoring Report. The
derived values of Action and Limit Levels for CWD monitoring were summarised in
Table 6.1.

|
Notes: (referring to the baseline monitoring report) (1) Action Level – running quarterly STG & ANI will be calculated from the three preceding survey months. (2) Limit Level – two consecutive running quarters mean both the running quarterly encounter rates of the preceding month and the running quarterly encounter rates of this month. (3) Action Level and/or Limit Level will be triggered if both STG and ANI fall below the criteria. |

CWD
Monitoring Transects and Stations
6.2.1
Small Vessel Line-transect Survey
Small
vessel line-transect surveys were conducted along the transects covering
Northeast Lantau (NEL), Northwest Lantau (NWL), Airport West (AW), West Lantau
(WL) and Southwest Lantau (SWL) areas as proposed in the Manual, which are
consistent with the Agriculture, Fisheries and Conservation Department (AFCD)
long-term monitoring programme (except the addition of AW). The AW transect has
not been previously surveyed in the AFCD programme due to the restrictions of
HKIA Approach Area, nevertheless, this transect was established during the EIA
of the 3RS Project and refined in the Manual with the aim to collect project
specific baseline information within the HKIA Approach Area to fill the data
gap that was not covered by the AFCD programme. This also provided a larger
sample size for estimating the density, abundance and patterns of movements in
the broader study area of the project.
The planned vessel survey
transect lines follow the waypoints set for construction phase monitoring as
proposed in the Manual and depicted in Figure 6.1 with the waypoint coordinates
of all transect lines given in Table
6.2, which are subject to on-site refinement based on
the actual survey conditions and constraints.

Land-based Theodolite Tracking Survey
Land-based
theodolite tracking survey stations were set up at two locations, one facing
east/south/west on the southern slopes of Sha Chau (SC), and the other facing
north/northeast/northwest at Lung Kwu Chau (LKC). The stations (D and E)
are depicted in Figure 6.2 and shown in Table 6.3
with position coordinates, height of station and approximate distance of
consistent theodolite tracking capabilities for CWD.

CWD
Monitoring Methodology
6.3.1
Small Vessel Line-transect Survey
Small vessel line-transect
surveys provided data for density and abundance estimation and other
assessments using distance-sampling methodologies, specifically, line-transect
methods.
The surveys involved small vessel
line-transect data collection and have been designed to be similar to, and
consistent with, previous surveys for the AFCD for their long-term monitoring
of small cetaceans in Hong Kong. The survey was designed to provide systematic,
quantitative measurements of density, abundance and habitat use.
As mentioned in Section 6.2.1,
the transects covered NEL, NWL covering the AW, WL and SWL areas as proposed in
the Manual and are consistent with the AFCD long-term monitoring programme
(except AW). There are two types of transect lines:
● Primary transect lines: the
parallel and zigzag transect lines as shown in Figure 6.1; and
● Secondary transect lines:
transect lines connecting between the primary transect lines and going around
islands.
All data collected on both
primary and secondary transect lines were used for analysis of sighting
distribution, group size, activities including association with fishing boat,
and mother-calf pairs. Only on-effort data collected under conditions of
Beaufort 0-3 and visibility of approximately 1200 m or beyond were used for
analysis of the CWD encounter rates.
A 15-20m vessel with a flying
bridge observation platform about 4 to 5m above water level and unobstructed
forward view, and a team of three to four observers were deployed to undertake
the surveys. Two observers were on search effort at all times when
following the transect lines with a constant speed of 7 to 8 knots (i.e. 13 to
15km per hour), one using 7X handheld binoculars and the other using unaided
eyes and recording data.
During on-effort survey periods,
the survey team recorded effort data including time, position (waypoints),
weather conditions (Beaufort sea state and visibility) and distance travelled
in each series with assistance of a handheld GPS device. The GPS device also
continuously and automatically logged data including time, position (latitude
and longitude) and vessel speed throughout the entire survey.
When CWDs were seen, the survey
team was taken off-effort, the dolphins were approached and photographed for
photo-ID information (using a Canon 7D [or similar] camera and long 300 mm+
telephoto lens), then followed until they were lost from view. At that
point, the boat returned (off effort) to the survey line at the closest point after
obtaining photo records of the dolphin group and began to survey on effort
again.
Focal follows of dolphins would
be used for providing supplementary information only where practicable (i.e.
when individual dolphins or small stable groups of dolphins with at least one
member that could be readily identifiable with unaided eyes during observations
and weather conditions are favourable). These would involve the boat following
(at an appropriate distance to minimise disturbance) an identifiable individual
dolphin for an extended period of time, and collecting detailed data on its
location, behaviour, response to vessels, and associates.
6.3.2
Photo Identification
CWDs can be identified by their unique features
like presence of scratches, nick marks, cuts, wounds, deformities of
their dorsal fin and distinguished colouration and spotting patterns.
When CWDs were observed, the survey team was
taken off-effort, the dolphins were approached and photographed for
photo-ID information (using a Canon 7D [or similar] camera and long 300 mm+
telephoto lens). The survey team attempted to photo both sides of every single
dolphin in the group as the colouration and spotting pattern on both sides may
not be identical. The photos were taken at the highest available resolution and
stored on Compact Flash memory cards for transferring into a computer.
All photos taken were initially
examined to sort out those containing potentially identifiable individuals.
These sorted-out images would then be examined in detail and compared to the
CWD photo-identification catalogue established for 3RS during the baseline
monitoring stage.
6.3.3
Land-based Theodolite Tracking Survey
Land-based theodolite tracking survey obtains
fine-scale information on the time of day and movement patterns of the
CWDs. A digital theodolite (Sokkia/Sokkisha Model DT5 or similar
equipment) with 30-power magnification and 5-s precision was used to obtain the vertical and horizontal angle of each
dolphin and vessel position. Angles
were converted to geographic coordinates (latitude and longitude) and
data were recorded using Pythagoras software, Version 1.2. This
method delivers precise positions of multiple
spatially distant targets in a short period of time. The
technique is fully non-invasive, and allows for time and cost-effective
descriptions of dolphin habitat use patterns at all times of daylight.
Three surveyors (one theodolite
operator, one computer operator, and one observer) were involved in each survey.
Observers searched for dolphins using unaided eyes and handheld binoculars
(7X50). Theodolite tracking sessions were initiated whenever an individual CWD
or group of CWDs was located. Where possible, a distinguishable
individual was selected, based on colouration, within the group. The
focal individual was then continuously tracked via the theodolite, with a
position recorded each time the dolphin surfaced. In case an individual could
not be positively distinguished from other members, the group was tracked by
recording positions based on a central point within the group whenever the CWD
surfaced. Tracking continued until animals were lost from view; moved beyond
the range of reliable visibility (>1-3km, depending on station height); or
environmental conditions obstructed visibility (e.g., intense haze, Beaufort
sea state >4, or sunset), at which time the research effort was
terminated. In addition to the tracking of CWD, all vessels that moved
within 2-3km of the station were tracked, with effort made to obtain at least
two positions for each vessel.
Theodolite tracking included
focal follows of CWD groups and vessels. Priority was given to tracking
individual or groups of CWD. The survey team also attempted to track all
vessels moving within 1 km of the focal CWD.

Monitoring
Results and Observations
6.4.1
Small Vessel Line-transect Survey
Within this reporting period, two complete sets
of small vessel line-transect surveys were conducted on the 7, 8, 11, 12, 13,
21, 22 and 29 November 2019, covering all transects in NEL, NWL, AW, WL and SWL
survey areas for twice.
A total of around 454.80 km of survey effort
was collected from these surveys and around 96.7% of the survey effort was
being conducted under favourable weather condition (i.e. Beaufort Sea State 3
or below with favourable visibility). Details of the survey effort are given in
Appendix C.
Sighting
Distribution
In November 2019, 12 sightings with 26 dolphins
were sighted. Amongst these sightings, 11 sightings with 24 dolphins are
on-effort sightings under favourable weather condition (i.e. Beaufort Sea State
3 or below with favourable visibility). Details of cetacean sightings are
presented in Appendix C.
Distribution of all CWD sightings recorded in
November 2019 is illustrated in Figure 6.3. In NWL including the AW
transect, the CWD sightings were distributed at the southwestern part of the
survey area, the central part of SCLKCMP and also the waters between Lung Kwu
Chau and Lung Kwu Tan. In WL, CWD sightings were recorded from Tai O to Peaked
Hill. In SWL, CWD sightings were located at the coastal waters around Fan Lau
Tung Wan and Lo Kei Wan. No sightings of CWD were recorded in NEL or in close
vicinity of the 3RS works area.
Figure 6.3:
Sightings Distribution of Chinese White Dolphins
Encounter Rate
Two types of dolphin encounter rates were
calculated based on the data from November 2019. They included the number of
dolphin sightings per 100 km survey effort (STG) and total number of dolphins
per 100 km survey effort (ANI) in the whole survey area (i.e. NEL, NWL, AW, WL
and SWL). In the calculation of dolphin encounter rates, only survey data
collected under favourable weather condition (i.e. Beaufort Sea State 3 or
below with favourable visibility) were used. The formulae used for calculation
of the encounter rates are shown below:
Encounter
Rate by Number of Dolphin Sightings (STG)
Encounter
Rate by Number of Dolphins (ANI)
(Notes: Only data
collected under Beaufort 3 or below condition were used)
In November 2019, a total of around 439.80 km
of survey effort were conducted under Beaufort Sea State 3 or below with
favourable visibility, whilst a total number of 11 on-effort sightings with 24
dolphins were sighted under such condition. Calculation of the encounter rates
in November 2019 are shown in Appendix C.
For the running quarter of the reporting period
(i.e., from September 2019 to November 2019), a total of around 1315.31 km of
survey effort were conducted under Beaufort Sea State 3 or below with
favourable visibility, whilst a total number of 45 on-effort sightings and a
total number of 153 dolphins from on-effort sightings were obtained under such
condition. Calculation of the running quarterly encounter rates are shown in Appendix C.
The STG and ANI of CWD in the whole survey area
(i.e. NEL, NWL, AW, WL and SWL) during the month of November 2019 and during the
running quarter are presented in Table
6.4 below and compared
with the Action Level. The running quarterly encounter rates STG and ANI did
not trigger Action Level.

Group Size
In November 2019, 12 groups with 26 dolphins
were sighted, and the average group size of CWDs was 2.2 dolphins per group.
Sightings with small group size (i.e. 1-2 dolphins) were dominant. No CWD
sighting with large group size (i.e. 10 or more dolphins) was recorded.
Activities
and Association with Fishing Boats
Two sightings of CWDs were recorded engaging in
feeding activities in November 2019. No CWD sightings were observed in
association with operating fishing boat in the reporting month.
Mother-calf Pair
In November 2019, there was no sighting of CWD
with the presence of mother-and-calf pair.
6.4.2
Photo Identification
In November 2019, a total number of 20
different CWD individuals were identified for totally 21 times. A summary of photo
identification works is presented in Table 6.5. Representative photos of
these individuals are given in Appendix C.

Land-based Theodolite Tracking Survey
Survey
Effort
Land-based theodolite tracking
surveys were conducted at LKC on 12 and 21 November 2019 and at SC on 28 November 2019, with a
total of three days of land-based theodolite tracking survey effort
accomplished in this reporting period. Two CWD groups were tracked at LKC
station during the surveys. Information of survey effort and CWD groups sighted
during these land-based theodolite tracking surveys are presented in Table 6.6.
Details of the survey effort and CWD groups tracked are presented in Appendix C. The first sighting locations
of CWD groups tracked at LKC station during land-based theodolite tracking surveys
in November 2019 were depicted in Figure 6.4. No CWD group was sighted
from SC station in this reporting month.

Progress Update on Passive Acoustic Monitoring
Underwater acoustic monitoring using Passive Acoustic
Monitoring (PAM) should be undertaken during land formation related
construction works. In this reporting period, the Ecological Acoustic Recorder
(EAR) was remained underwater and positioned at south of Sha Chau Island inside
the SCLKCMP with 20% duty cycle (Figure 6.5). The EAR deployment is
generally for 6 weeks prior to data retrieval for analysis. Acoustic data is
reviewed to give an indication of CWDs occurrence patterns and to obtain
anthropogenic noise information simultaneously. Analysis (by a specialised team
of acousticians) involved manually browsing through every acoustic recording
and logging the occurrence of dolphin signals. All data will be re-played by
computer as well as listened to by human ears for accurate assessment of
dolphin group presence. As the period of data collection and analysis takes
more than four months, PAM results could not be reported in monthly intervals
but report for supplementing the annual CWD monitoring analysis.
6.6
Site Audit for CWD-related Mitigation Measures
During the reporting period, silt
curtains were in place by the contractor for marine filling , in which dolphin
observers were deployed by contractor in accordance with the MMWP. Overall, 4
to 8 dolphin observation stations and teams of at least two dolphin observers
were deployed by the contractors for continuous monitoring of the DEZ for DCM
works and seawall construction in accordance with the DEZ Plan. Trainings for
the proposed dolphin observers on the implementation of MMWP and DEZ monitoring
were provided by the ET prior to the aforementioned works, with a cumulative
total of 679 individuals being trained and the training records kept by the ET.
From the contractors’ MMWP observation records, no dolphin or other marine
mammals were observed within or around the silt curtains. As for DEZ monitoring
records, no dolphin or other marine mammals were observed within or around the
DEZs in this reporting month. These contractors’ records were also audited by
the ET during site inspection.
Audits of acoustic decoupling
measures for construction vessels were carried out during weekly site
inspection and the observations are summarised in Section 7.1. Audits of
SkyPier high speed ferries route diversion and speed control and construction
vessel management are presented in Section 7.2 and Section 7.3
respectively.
6.7
Timing of
Reporting CWD Monitoring Results
Detailed analysis of CWD
monitoring results collected by small vessel line-transect survey will be
provided in future quarterly reports. Detailed analysis of CWD monitoring
results collected by land-based theodolite tracking survey and PAM will be
provided in future annual reports after a larger sample size of data has been
collected.
6.8
Summary of CWD Monitoring
Monitoring of CWD was conducted with two complete sets of small vessel line-transect surveys and three days of land-based theodolite tracking survey effort as scheduled. The running quarterly encounter rates STG and ANI in the reporting period did not trigger the Action Level for CWD monitoring.

Environmental Site Inspection and Audit
7.1
Environmental Site Inspection
Site
inspections of the construction works were carried out on a weekly basis to
monitor the implementation of proper environmental pollution control and
mitigation measures for the Project. The weekly site inspection schedule of the
construction works is provided in Appendix C. Bi-weekly site inspections
were also conducted by the IEC. Besides, ad-hoc site inspections were
conducted by ET and IEC if environmental problems were identified, or
subsequent to receipt of an environmental complaint, or as part of the
investigation work. These site inspections provided a direct means to reinforce
the specified environmental protection requirements and pollution control
measures in construction sites.
During site inspections,
environmental situation, status of implementation of pollution control and
mitigation measures were observed. Environmental documents and site records,
including waste disposal record, maintenance record of environmental equipment,
and relevant environmental permit and licences, were also checked on site. Observations were recorded in the
site inspection checklist and passed to the contractor together with the
appropriate recommended mitigation measures where necessary in order to
advise contractors on environmental improvement, awareness and on-site
enhancement measures. The
observations were made with reference to the following information during the
site inspections:
·
The EIA and EM&A requirements;
·
Relevant environmental protection laws, guidelines, and practice notes;
·
The EP conditions and other submissions under the EP;
·
Monitoring results of EM&A programme;
·
Works progress and programme;
·
Proposal of individual works;
·
Contract specifications on environmental protection; and
·
Previous site inspection results.
Good site practices were observed
in site inspections during the reporting period. Advice were given when
necessary to ensure the construction workforce were familiar with relevant
procedures, and to maintain good environmental performance on site. Regular
toolbox talks on environmental issues were organised for the construction
workforce by the contractors to ensure understanding and proper implementation of
environmental protection and pollution control mitigation measures.
During the reporting period,
implementation of recommended landscape and visual mitigation measures (CM1 –
CM10) where applicable was monitored weekly in accordance with the Manual and
no non-conformity was recorded. In case of non-conformity, specific
recommendations will be made, and actions will be proposed according to the
Event and Action Plan. The monitoring status is summarised in Appendix A.
A
summary of implementation status of the environmental mitigation measures for
the construction phase of the Project during the reporting period is provided
in Appendix A.
7.2
Audit of SkyPier High Speed Ferries
The Marine Travel Routes
and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan) was
submitted to the Advisory Council on the Environment for comment and
subsequently submitted to and approved by EPD in November 2015 under EP
Condition 2.10. The approved SkyPier Plan is available on the dedicated website
of the Project. In the SkyPier Plan, AAHK has committed to implement the
mitigation measure of requiring HSFs of SkyPier travelling between HKIA and
Zhuhai / Macau to start diverting the route with associated speed control
across the area, i.e. Speed Control Zone (SCZ), with high CWD abundance. The
route diversion and speed restriction at the SCZ have been implemented since 28
December 2015.
Key audit findings for the
SkyPier HSFs travelling to/from Zhuhai and Macau against the requirements of
the SkyPier Plan during the reporting period are summarised in Table 7.1. The daily
movements of all SkyPier HSFs in this reporting period (i.e., 79 to 82 daily
movements were within the maximum daily cap of 125 daily movements. Status of
compliance with the annual daily average of 99 movements will be further
reviewed in the annual EM&A Report.
In total, 510 ferry movements
between HKIA SkyPier and Zhuhai / Macau were recorded in November 2019 and the
data are presented in Appendix F. The time spent by the
SkyPier HSFs travelling through the SCZ in November 2019 were presented in Figure 7.1.
It will take 9.6 minutes to travel through the SCZ when the SkyPier HSFs adopt
the maximum allowable speed of 15 knots within the SCZ. Figure 7.1 shows that all of the SkyPier HSFs spent
more than 9.6 minutes to travel through the SCZ.
Figure 7.1: Duration of the SkyPier HSFs
travelling through the SCZ for November 2019
Note: Data
above the red line indicated that the time spent by the SkyPier HSFs travelling
through the SCZ is more than 9.6 minutes, which is in compliance with the
SkyPier Plan.
A meeting was held with the ferry
operators on 20, 27 and 28 November 2019 to review and discuss the deviation
cases happened during the past few months as well as to share experience and

Audit of
Construction and Associated Vessels
ET carried out the following
actions during the reporting period:
- One
skipper training session was held for contractors’ concerned skippers of
relevant construction vessels to familiarize them with the predefined
routes; general education on local cetaceans; guidelines for avoiding
adverse water quality impact; the required environmental practices /
measures while operating construction and associated vessels under the
Project; and guidelines for operating vessels safely in the presence of
CWDs. The list of all trained skippers was properly recorded and
maintained by ET
- Three
skipper training sessions were held by a contractor’s Environmental
Officer. Competency tests were subsequently conducted with the trained
skippers by ET. The list of all trained skippers was properly recorded and
maintained by ET.
- In
this reporting period, 2 skippers were trained by ET and 4 skippers were
trained by a contractor’s Environmental Officer. In total, 1259 skippers
were trained from August 2016 to November 2019.
- The
MSS automatically recorded deviation cases such as speeding, entering no
entry zone and not travelling through the designated gate. ET conducted
checking to ensure the MSS records deviation cases accurately.
- Deviations
such as speeding in the works area, entered no entry zone, and entering
from non-designated gates were identified. All the concerned contractors
were reminded to comply with the requirements of the MTRMP-CAV during the
bi-weekly MTCC audit.
- Three-month
rolling programmes (one month record and three months forecast) for
construction vessel activities were received from the contractors in order
to help maintain the number of construction and associated vessels on site
to a practicable minimal level.

Conclusion and Recommendation
The key
activities of the Project carried out in the reporting period included
reclamation works and land-side works. Reclamation works included DCM works,
marine filling and seawall construction. Land-side works involved mainly
airfield works, foundation and substructure work for Terminal 2 expansion,
modification and tunnel work for APM and BHS systems, and preparation work for
utilities, with activities include site establishment, site office
construction, road and drainage works, cable ducting, demolition of existing
facilities, piling, and excavation works.
All the monitoring works for
construction dust, construction noise, water quality, construction waste,
landscape & visual, and CWD were conducted during the reporting period in
accordance with the Manual.
Monitoring
results of construction dust, construction noise, construction waste, and
CWD did not trigger the corresponding Action and Limit Levels during the
reporting period.
The water quality monitoring
results for DO, turbidity, total alkalinity, nickel, and chromium obtained
during the reporting period were within the corresponding Action and Limit
Levels stipulated in the EM&A programme. Relevant investigation and follow-up
actions will be conducted according to the EM&A programme if the
corresponding Action and Limit Levels are triggered. For SS, one testing result
triggered the relevant Action Level, and the corresponding investigation was
conducted accordingly. The investigation findings concluded that the case was
not related to the Project. To conclude, the construction activities in the
reporting period did not introduce adverse impact to all water quality
sensitive receivers.
Weekly site inspections of the
construction works were carried out by the ET to audit the implementation of
proper environmental pollution control and mitigation measures for the Project.
Bi-weekly site inspections were also conducted by the IEC. Site inspection
findings were recorded in the site inspection checklists and provided to the
contractors to follow up.
On the implementation of the
SkyPier Plan, the daily movements of all SkyPier HSFs in November 2019 were in
the range of 79 to 82 daily movements, which are within the maximum daily cap
of 125 daily movements. A total of 510 HSF movements under the SkyPier Plan
were recorded in the reporting period. The average speeds of all HSFs
travelling through the SCZ ranged from 10.5 to 14.0 knots. All HSFs had
travelled through the SCZ with average speeds under 15 knots in compliance with
the SkyPier Plan. Zero deviation from the diverted route in November 2019 were
recorded in the HSF monitoring. In summary, the ET and IEC have audited the HSF
movements against the SkyPier Plan and conducted follow up investigations or
actions accordingly.
On the implementation of
MTRMP-CAV, the MSS automatically recorded the deviation case such as speeding,
entering no entry zone and not travelling through the designated gates. ET
conducted checking to ensure the MSS records all deviation cases accurately.
Training has been provided for the concerned skippers to facilitate them in
familiarising with the requirements of the MTRMP-CAV. Deviations including
speeding in the works area, entered no entry zone, and entry from
non-designated gates were reviewed by ET. All the concerned captains were
reminded by the contractor’s MTCC representative to comply with the
requirements of the MTRMP-CAV. The ET reminded contractors that all vessels
shall avoid entering the no-entry zone, in particular the Brothers Marine Park and the Sha
Chau & Lung Kwu Chau Marine Park. Three-month rolling programmes for
construction vessel activities, which ensures the proposed vessels are
necessary and minimal through good planning, were also received from
contractors.
