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 accordance with the
Updated EM&A Manual (the Manual).
This is the 67th Construction Phase
Monthly EM&A Report for the Project which summarises the monitoring results
and audit findings of the EM&A programme during the reporting period from 1
to 31 July 2021.
Key Activities in the Reporting Period
The key activities of the Project
carried out in the reporting period included reclamation works and land-based
works. Works in the reclamation areas included marine filling, seawall and
facilities construction, together with runway and associated works such as
bored piling for approach lights. Land-based works on existing airport island
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.

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 all
parameters, except suspended solids (SS), 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, some of the testing results triggered the
relevant Action or Limit Levels, and the corresponding investigations were
conducted accordingly. The investigation findings revealed that the cases were
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.

Taking into account the construction works in
this reporting period, impact monitoring of air quality, noise, water quality,
waste management, landscape & visual, and CWD were carried out in the
reporting period.
The EM&A programme also involved weekly
site inspections and related auditing conducted by the ET for checking the
implementation of the required environmental mitigation measures recommended in
the approved EIA Report. To promote the environmental awareness and
enhance the environmental performance of the contractors, environmental
trainings and regular environmental management meetings were conducted
during the reporting period, which are summarised as below:
● Seventeen environmental management meetings for EM&A review with
works contracts: 2, 8, 9, 13, 14, 19, 21, 22, 23, 29 and 30 July 2021.
The EM&A programme has been following the
recommendations presented in the approved EIA Report and the Manual. 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.

Air Quality Monitoring
Air quality monitoring of 1-hour Total
Suspended Particulates (TSP) was conducted three times every six days at two
representative monitoring stations in the vicinity of air sensitive receivers
in Tung Chung and villages in North Lantau in accordance with the Manual. Table 2.1
describes the details of the monitoring stations. Figure 2.1 shows the locations of the
monitoring stations.

Monitoring 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 D of Construction Phase
Monthly EM&A Report No. 65, and the calibration certificates of portable direct reading dust meters listed in Table 2.3 are valid in the reporting period.

reporting period.
General meteorological conditions throughout
the impact monitoring period were recorded. Wind data including wind speed and
wind direction for each monitoring day were collected from the Chek Lap Kok Wind Station.
2.5
Conclusion
No dust emission source was observed at the
monitoring stations during the monitoring sessions. As the sensitive receivers
were far away from the construction activities, with the implementation of dust
control measures, there was no adverse impact at the sensitive receivers
attributable to the works of the Project.

Noise Monitoring
Noise monitoring in the form of 30-minute
measurements of Leq, L10, and L90
levels was conducted once per week between 0700 and 1900 on normal weekdays at
four representative monitoring stations in the vicinity of noise sensitive
receivers in Tung Chung and villages in North Lantau in accordance with the
Manual. Table 3.1 describes the details of the monitoring stations. Figure 2.1 shows the locations of the

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, when
higher than the baseline monitoring levels, 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

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

Test took place on 13 July during this reporting period.
(3)
Some of the noise
measurement results were higher than the baseline monitoring levels. In order
to reduce the influence of non-Project related noise on the monitoring results,
these measurement results were corrected with reference to the baseline
monitoring levels.
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, school activities at NM4 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 and suspended solids (SS) 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) 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.
(3) 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.
(4)
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

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 and water depth were collected by equipment listed in Table 4.4 and
Table 4.5.
Water samples for 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).
Calibration certificates of the monitoring
equipment used in the reporting period are listed in Table 4.4.
4.3.3
Laboratory Measurement / Analysis
Analysis of SS 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 determination.
The SS determination works were started within 24 hours after collection of the
water samples. The analysis of SS have followed the standard methods summarised
in Table 4.6. The
QA/QC procedures for laboratory measurement/ analysis of SS 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. Monitoring
sessions on 20 July 2021 was cancelled due to Strong Wind Signal No. 3 in
force.
The
water quality monitoring results for all parameters, except SS, obtained during
the reporting period were within their corresponding Action and Limit Levels. The detailed monitoring results
are presented in Appendix C.
For SS, some of the testing results triggered
the corresponding Action and Limit Levels, and investigations were conducted accordingly.

In accordance with Event and Action Plan
stipulated in the Manual, EPD, IEC and Contractor were informed when the
corresponding Action or Limit Levels were triggered.
Investigation focusing on the case which
occurred at a monitoring station located downstream of the Project was carried
out. Details of the Project’s marine construction activities and site
observations of the concerned monitoring day were collected. Findings were
summarized in Table 4.9.

The investigation confirmed that marine piling

The silt curtains were maintained properly and checked by ET regularly.
For SS result recorded in ebb tide at IM4 on 8
July 2021 which triggered the corresponding Action Level, no silt plume was
observed at this monitoring station and appropriate mitigation measures were
implemented properly by the contractor. No muddy water discharges from outfalls
of the reclaimed land were observed. Moreover, the location of IM4 was far away
(i.e. at least 5.5km) from the nearest marine construction activity of the
Project, so it was unlikely affected by the Project. Therefore, the case was
considered unlikely due to the Project.
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 a minor
number of SS measurement results triggered the corresponding Action and Limit
Levels, and investigations were conducted accordingly.
Based on the investigation findings, all
results that triggered the corresponding Action Level and Limit Levels were 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. These cases 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 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.
5.1
Action
and Limit Levels
The Action and Limit Levels of the construction
waste are provided in Table 5.1.

Waste
Management Status
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 have taken
actions to implement the recommended measures. Waste management audits were
carried out by ET according to the requirement of the Waste Management Plan,
Updated EM&A Manual and the implementation schedule of the waste management
mitigation measures in Appendix A.
Based on updated information
provided by contractors, construction waste generated in the reporting period
is summarised in Table 5.2.
Proactive measures have been undertaken during the re-configuration of T2
building. The contractor has established the recycling strategy for
C&D materials with proper planning and design to maximize recycling and
reuse. Dedicated recyclers were employed for different kinds of
recyclable materials by the contractor, and ET and IEC have carried out site
visit to recyclers’ faciltities to review recycling
process. Dedicated areas for sorting of materials are established on
site. Recyclable materials such as steel, reinforcement bar, structural steel, aluminum, copper, other metals and glass are sorted on-site
and transported off-site for recycling. ET and IEC have carried out site audits
regularly and reviewed the trip ticket system.

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.
Along with the design and construction
progress, further development on the treatment level/details and the re-use
mode for marine sediment generated from 3RS Project has been conducted
according to the EIA recommendation.
5.3
Marine
Sediment Management
Marine sediment is managed according to the EIA
Report, Updated EM&A Manual and Waste Management Plan of the Project. The
sampling process, storage conditions of the excavated marine sediment,
treatment process, final backfilling location as well as associated records
were inspected and checked by ET and verified by IEC to ensure they were in
compliance with the requirements as stipulated in the Waste Management Plan.
Sampling works for marine sediment generated
from the reclaimed land area was on-going during the reporting period. The
details of the marine sediment sampling, treatment and backfilling will be
reported in the subsequent EM&A Reports upon completion.

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.
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.

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
following the waypoints set for construction phase monitoring as proposed in
the Manual are 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.

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, AW, WL and SWL areas as proposed in the Manual, which 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 favourable 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 15 km 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 photograph 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 Project 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.
6.4
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 12,
13, 14, 19, 21, 22, 26 and 28 July 2021, covering all transects in NEL, NWL,
AW, WL and SWL survey areas for twice.
A total of around 432.30 km of
survey effort was collected from these surveys and around 98.1% 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 July 2021, 30 sightings with
93 dolphins were sighted. Amongst these sightings, 29 sightings with 90
dolphins are on-effort records 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 July 2021 is illustrated in Figure 6.3. In WL, CWD
sightings were scattered between Tai O and Fan Lau with more CWD groups sighted
between Tai O and Yi O. In SWL, the majority of the CWD sightings were recorded
within or south to the Southwest Lantau Marine Park. After three months of nil
sighting in NWL between April and June 2021, CWD were re-occurring in NWL in
this reporting month. Three CWD sightings were sighted in Urmston
Road waters between Lung Kwu Tan and SCLKCMP while
other two CWD sightings were recorded at the southwestern corner of the survey
area. There was no CWD sighting recorded in NEL survey area during the
reporting period.
Figure 6.3: Sightings Distribution of
Chinese White Dolphins
Remarks: (1) Please note that there are 30 pink circles on
the map indicating the sighting locations of CWDs. Some of them were very close
to each other and therefore may appear overlapped on this distribution map. (2)
Marine park excludes land area and the landward boundary generally follows the
high water mark along the coastline.
Encounter Rate
Two types of dolphin encounter
rates were calculated based on the vessel survey data. 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 July 2021, a total of around 424.23
km of survey effort were conducted under Beaufort Sea State 3 or below with favourable visibility, whilst a total number of 29
on-effort sightings with 90 dolphins were sighted under such condition.
Calculation of the encounter rates for the month are shown in Appendix C.
For the running quarter of the
reporting period (i.e., from May to July 2021), a total of around 1116.93 km of
survey effort were conducted under Beaufort Sea State 3 or below with favourable visibility, whilst a total number of 49
on-effort sightings and a total number of 145 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 July 2021
and during the running quarter are presented in Table 6.4 below and compared with the Action Level.
Although the running quarterly encounter rate ANI fall below the Action
Level, the Action Level is not triggered as the running quarterly STG remain
above the Action Level.

Group Size
In July 2021, 30 groups of 93 dolphins
in total were sighted, and the average group size of CWDs was 3.10 dolphins per
group. Number of sightings with medium group size (i.e. 3-9 dolphins) was
slightly higher than that with small group size (i.e. 1-2 dolphins). There were
no CWD sightings with large group size (i.e. 10 or more dolphins).
Activities and Association with Fishing Boats
Eleven CWD sightings were
recorded engaging in feeding activities in July 2021 and four sightings were
observed in association with operating purse seiners. Two of these sightings
were recorded in WL and the other two were sighted in SWL.
Mother-calf
Pair
In July 2021, there were two CWD
sightings recorded with the presence of mother-and-unspotted juvenile pair.
These two sightings were recorded in NWL and WL respectively.
6.4.2
Photo
Identification
In
July 2021, a total number of 35 different CWD individuals were identified for totally
50 times. A summary of photo identification works is presented in Table 6.5.
Representative photos of these individuals are given in Appendix C.

Progress Update on Passive Acoustic Monitoring
Underwater
acoustic monitoring using Passive Acoustic Monitoring (PAM) should be
undertaken during land formation related construction works. Both C-POD and
F-POD are considered as effective PAM devices in detecting CWD occurrence, and
F-POD was the main PAM device deployed where feasible. During this reporting
period, the F-POD was remained underwater and positioned at south of Sha Chau
Island inside the SCLKCMP (Figure
6.5). The F-POD was last deployed on 20 May 2021 and the next
re-deployment is scheduled in early August 2021 to retrieve the data for
analysis. Acoustic data would be reviewed to give an indication of CWDs
occurrence patterns and anthropogenic noise information. Analysis would involve
use of proprietary software for objective automated data analyses and
experienced analysts to perform visual validation for assessment of dolphin
detection. As the period of data collection and analysis takes about 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, 2 to 7 dolphin
observation stations and teams of at least two dolphin observers were deployed
by the contractors for continuous monitoring of the DEZ for bored piling and
seawall construction works 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 704 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 7.4
and Section 7.5 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 two 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 B. 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 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.
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
Landscape and Visual Mitigation Measures
Implementation of applicable landscape and
visual mitigation measures (reference to the environmental protection measures
CM1 – CM10 in Appendix A) was monitored in accordance
with the Manual. All measures undertaken by both the contractor and the
landscape contractor during the construction phase and first year of the
operation phase shall be audited by a landscape architect, as a member of the
ET, on a regular basis to ensure compliance with the intended aims of the
measures. Site inspections shall be undertaken at least once every two months
during the operation phase.
The implementation status of the
environmental protection measures are summarized below in Table 7.1. Examples of landscape and
visual mitigation measures are shown in Table 7.2. The monitoring programme for
detailed design, construction, establishment works and long term management (10
years) stages is presented in Table
7.3. Event and Action Plan for Landscape and Visual impacts
is stated in Table 7.4.

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.
Due to the COVID-19 pandemic, all SkyPier HSF services to/from Zhuhai and Macau have been
suspended from 25 March 2020 until further notice. No ferry movement between
HKIA SkyPier and Zhuhai and Macau was recorded in
July 2021. 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 7.8.
The daily movement of all SkyPier
HSFs, including those not using the diverted route, in this reporting period
(i.e., 2 to 3 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.
As
updated by CLP Power, the construction works of the Hong Kong Offshore LNG
Terminal Project may affect the route diversion operation of the SkyPier HSFs from Q3 to Q4 2021. The captains were informed
on the issue and ET will continue to closely monitor the implementation of the SkyPier Plan in the period.

Audit of Construction and Associated Vessels
ET carried out the following actions during the
reporting period:
- One skipper training session was
held by contractor’s Environmental Officer. Competency test was
subsequently conducted with the trained skipper by ET. The list of all trained
skippers was properly recorded and maintained by ET.
- In
this reporting period, no skipper was trained by ET and 1 skipper was
trained by contractor’s Environmental Officer. In total, 1788 skippers
were trained from August 2016 to July 2021.
- 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 Construction Traffic Control Centre (CTCC) 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.

Analysis and Interpretation of Complaints,
Notification of Summons and Status of Prosecutions
7.9.1
Complaints
Complaints received in the previous
reporting period
As reported in the previous Monthly EM&A
Report, two complaints were received in the previous reporting period.
· A complaint regarding dust issue at
the eastern quay of the Project received on 21 June 2021; and
· A complaint regarding muddy water
from the Project received on 28 June 2021.
The cases were investigated by ET in accordance
with the Manual and the Complaint Management Plan of the Project. The findings
of investigation are presented below.
Complaint regarding dust issue received on 21
June 2021
With the information provided by the
complainant on 21 June 2021 and subsequently on 8 July 2021, ET recognised the
concerned areas and three identified related contractors and requested them to
provide information regarding the complaint. Based on the
information provided by the contractors, water trucks were assigned to carry
out regular water spraying along the concerned areas according to their dust
control management plan and provided their water spraying record for June and
July 2021. Based on the ET’s weekly site inspections and ad-hoc
inspection, no observation related to dust issue was recorded. A joint
inspection by EPD, ET, IEC and AAHK was arranged after receiving the complaint,
in which the contractor was reminded to provide and maintain adequate dust
mitigation measures for haul roads in site areas and review the effectiveness
of dust control measures regularly. ET also observed another contractor was
conducting water spraying at concerned area during ET’s site inspection.
Nevertheless, all contractors were reminded to continue implementing water
spraying properly and adequately at their work areas. ET and IEC would continue
to monitor contractors' dust suppression measures during environmental site
inspections and the implementation of these measures at the concerned area.
Hence, the complaint case was considered closed.
Complaint regarding muddy water received
on 28 June 2021
With the photo provided by the complainant, ET
recognised the concerned area and identified five related contractors and
requested them to provide information regarding the complaint. Based on
the information provided by the contractors, no illegal discharge along
the alleged area during 21 to 25 June 2021 was reported. The temporary drainage system from one of the related
contractors was operating properly for water storage, reuse and recycling
onsite; and the sedimentation tanks from another contractor was
installed on-site and confirmed their wastewater would be treated before
discharge. Based on the ET’s
weekly site inspections, no illegal discharge was identified in the checklists.
Both the temporary
drainage system and sedimentation
tanks were observed operating properly during the regular site
inspections in June. No wastewater discharge was observed at the alleged area
during IEC’s ad-hoc site inspection in late June. A joint inspection by
EPD, ET, IEC and AAHK was also arranged after receiving the complaint. For the licensed discharge point
near the alleged area, no discharge of muddy water was observed. No observation indicating any illegal
discharge of muddy water from the vessels and pipes in accordance with the
provided photo. Furthermore, the Hong Kong Observatory issued four Amber
Rainstorm Warning Signals on 22, 23 and 24 June which might suggest the heavy
rainfall might resulting in surface runoff at the alleged area. As such, ET
would remind the contractors to pay attention on the possibility of surface run
off, especially during rainy season and carry out further improvement on current measures if needed.
ET and IEC would continue to monitor 3RS water quality and conduct site
inspections to check contractors’ environmental practice and compliances.
Hence, the complaint case was considered closed.
Complaint received in this
reporting period
A complaint regarding dust issue at
3RS construction site
area was received on 13 July 2021. The
case is under investigation and findings of the investigation will be reported
in the next Monthly EM&A Report.
7.9.2 Notifications of Summons or Status of Prosecution
Neither notification of summons nor prosecution
was received during the reporting period.
7.9.3
Cumulative Statistics
Cumulative
statistics on complaints, notifications of summons and status of prosecutions
are summarised in Appendix F.

8.4
Review
of the Key Assumptions Adopted in the EIA Report
With reference to Appendix E of the Manual, it
is noted that the key assumptions adopted in approved EIA report for the
construction phase are still valid and no major changes are involved. The
environmental mitigation measures recommended in the approved EIA Report remain
applicable and shall be implemented in undertaking construction works for the
Project.
9 Conclusion
and Recommendation
The key activities of the Project
carried out in the reporting period included reclamation works and land-based
works. Works in the reclamation areas included marine filling, seawall and
facilities construction, together with runway and associated works such as
bored piling for approach lights. Land-based works on existing airport island
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 all
parameters, except SS, 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, some of the testing results triggered the relevant Action or Limit
Levels, and the corresponding investigations were conducted accordingly. The
investigation findings concluded that the cases were 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, due to the COVID-19 pandemic, all SkyPier HSF services to/from Zhuhai and Macau have been
suspended from 25 March 2020 until further notice. No HSF movement between HKIA SkyPier and
Zhuhai and Macau was recorded during the reporting period. Therefore, no
deviation was recorded in the HSF monitoring in the reporting period. The daily
movements of all SkyPier HSFs in the reporting
period, including those not using the diverted route, were in the range of 2 to
3 daily movements, which are within the maximum daily cap of 125 daily
movements.
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. A training has been
provided for the concerned skipper 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 CTCC
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.
