Introduction
1.1
Background
On 7 November 2014, the
Environmental Impact Assessment (EIA) Report (Register No.: AEIAR-185/2014) for
the “Expansion of Hong Kong International Airport into a Three-Runway System”
(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) submitted under EP
Condition 3.1[1].
AECOM Asia Company Limited (AECOM) was employed by AAHK as the Independent
Environmental Checker (IEC) for the Project.
The Project covers the expansion
of the existing airport into a three-runway system (3RS) with key project
components comprising land formation of about 650 ha and all associated
facilities and infrastructure including taxiways, aprons, aircraft stands, a
passenger concourse, an expanded Terminal 2 (T2), all related airside and
landside works and associated ancillary and supporting facilities. The
submarine aviation fuel pipelines and submarine power cables also require
diversion as part of the works.
Construction of the Project is to
proceed in the general order of diversion of the submarine aviation fuel
pipelines, diversion of the submarine power cables, land formation, and
construction of infrastructure, followed by construction of superstructures.
The new North Runway was
commissioned in November 2022. Since then, HKIA has continued to operate with
two runways, with the Centre Runway temporarily closed for reconfiguration. The
reconfiguration works included relevelling of the runway pavement to tie in
with connecting taxiways, constructing new runway entry and exit taxiways,
building new wrap-around taxiways at both ends of the runway. With the
completion of the reconfiguration works, the flight check and aircraft crash
and rescue exercise were completed on the Centre Runway in September and
October 2024 respectively. Thereafter, the Three-runway System (3RS) was
commissioned on 28 November 2024.
The
summary of construction works programme can be referred to Section 1.4.

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 the Monthly EM&A

the 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.
3 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 stations.

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
Summary of
Monitoring Results
The noise monitoring
schedule of reporting period is provided in Appendix B.
The noise monitoring results in
the reporting period are summarised in Table 3.4.

Façade correction included;
(2) The
limit level will be reduced to 65dB(A) during school examination periods at
NM4. No school examination took place during this reporting period.
(3) Some
of the noise measurement results were higher than the baseline monitoring
levels. To reduce the influence of non-Project related noise on the monitoring
results, these measurement results were corrected with reference to the
baseline monitoring results.
No complaints were received from
any sensitive receiver as listed in Table 3.1
that triggered the Action Level. All monitoring results were 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 near 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.
4 Water Quality Monitoring
All water impact monitoring work has been completed, with results
presented in the Annual EM&A Report for 2023 and
to be included in the Final EM&A Report. Based on the analysis presented in Annual EM&A
Report for 2023, the post-construction phase water quality monitoring did not
reveal significant changes of the water quality when comparing with baseline
water quality monitoring, and it can be concluded that the marine works of the
Project during construction phase did not cause deterioration in or adverse
impacts on the marine water quality surrounding the Project site.
5
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.

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 contractors’
information, construction waste generated in the reporting period is summarised
in Table 5.2. The ET
and IEC have carried out site audits regularly and reviewed the trip ticket
system. Dedicated areas for sorting of materials are established on site.
Recyclable materials such as steel bar, metal strip, aluminium, paper and
plastic are sorted on-site and transported off-site for recycling during this
reporting period.

Marine
Sediment Management
Marine sediment is managed
according to the EIA Report, Updated EM&A Manual, Waste Management Plan and
the proposal of Further Development on Treatment Level / Details and the Reuse
Mode for Marine Sediment (hereinafter referred to as “Further Development
Proposal”) of the Project. The storage conditions of the treated marine
sediment, and final backfilling location 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 and Further
Development Proposal.
Backfilling
works for treated marine sediment was conducted during the reporting
period. The
details of the marine sediment sampling, treatment and backfilling can be
referred to Annual EM&A Report.

Chinese White Dolphin Monitoring
In accordance with Section 10.2.3.2 (4) of the Updated
EM&A Manual, the operation phase CWD monitoring will be conducted for a
period of at least 12 months after the full implementation of the North Lantau
Marine Park (NLMP) at a frequency of two full surveys per month. Following the
full implementation of the NLMP and the completion of post-construction phase
CWD monitoring in December 2024, the operation phase CWD monitoring was
commenced in January 2025.
6.1
CWD
Monitoring Transects
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 for operation phase CWD monitoring 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 6.1,
which are subject to on-site refinement based on the actual survey conditions
and constraints.

6.2 CWD
Monitoring Methodology
6.2.1
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.
● 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.
6.2.2
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 since the
baseline monitoring stage.
6.3
Monitoring
Results and Observations
6.3.1 Small Vessel
Line-transect Survey
Survey Effort
Within this reporting period, two
complete sets of small vessel line-transect surveys were conducted on the 3, 7,
8, 9, 11, 15, 17 and 22 April 2025 covering all transects in NEL, NWL, AW, WL
and SWL survey areas for twice.
A total of around 449.2 km of
survey effort was collected from these surveys and all 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 the current reporting period, seven sightings with 16
dolphins were sighted. All these sightings were on-effort records under
favourable weather condition (i.e. Beaufort Sea State 3 or below with
favourable visibility). Details of dolphin sightings are presented in Appendix C.
Distribution of all CWD sightings
recorded in the current reporting period is illustrated in Figure
6.2. In WL, the majority of CWD sightings were scattered between Tai O
and Fan Lau. In SWL, a CWD sighting was recorded at water offshore Fan Lau Tung
Wan. There was no CWD sighting recorded in NWL and NEL during the reporting
period.

6.2: Sightings Distribution of Chinese White Dolphins
Remarks: (1) Please note that there are seven pink circles on
the map indicating the sighting locations of CWDs. (2) Marine
park excludes land area and the landward boundary generally follows the
high water mark along the coastline.
Group
Size
In the current reporting period,
seven groups of 16 dolphins in total were sighted, and the average group size
of CWDs was 2.3 dolphins per group. Most of the CWD sightings were having small
group size (i.e. 1-2 dolphins) and no CWD sighting with large group size (i.e.
10 or more dolphins) was recorded during the current reporting period.
Activities
and Association with Fishing Boats
There was
no CWD sightings recorded engaging in foraging activities during the current
reporting period. No sighting was observed in association with boat activities.
Mother-calf
Pair
In this reporting period, there
was one CWD sighting recorded with the presence of mother-and-unspotted
juvenile pair(s). The sighting was recorded in WL survey area.
6.3.2
Photo
Identification
In the current reporting period,
a total number of eight different CWD individuals were identified for a total
of eight times. A summary of photo identification works is presented in Table 6.2. Representative photos of these individuals
are given in Appendix C.

6.4 Site
Audit for CWD-related Mitigation Measures
During the reporting period, no
dolphin observation station was deployed by the contractor for continuous
monitoring of the DEZ in accordance with the DEZ Plan. During this reporting
period, no training session were provided by the ET for the proposed dolphin
observers.
The construction vessel
management are presented in Section 7.5 below.
According to Section 10.6.2.2 of
the Updated EM&A Manual, audits of HSF implementation measures and Spill
Responses Plan implementation measures will be conducted once every three months and every six months respectively for one
year upon operation of 3RS. The first audit of HSF implementation measures was
conducted in February 2025. During the audit period from 28 November 2024 to 28
February 2025, all the HSFs complied with the HSF Plan. The second audit of HSF
implementation measures will be conducted in May 2025. The first audit of the
Spill Responses Plan measures will be conducted in May 2025.

Environmental Site Inspection and
Audit
7.1
Environmental
Site Inspection
Site
inspections of the construction works to audit the
implementation of proper environmental pollution control and mitigation
measures for the Project were conducted by ET and IEC on a weekly and bi-weekly
basis, respectively. The weekly site inspection schedule of the construction
works is provided in Appendix B.
Besides, ad-hoc site inspections were also 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 was 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 and OM7 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
first year of the operation phase.
The
implementation status of the environmental protection measures is 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

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.
During the reporting period, the SkyPier HSF travelling to/from Zhuhai/Macau has been
suspended until further notice. No ferry movement between HKIA SkyPier and Zhuhai/Macau was recorded in April 2025.

Key Environmental Issues for the Coming Reporting Period
8.2.1 Construction
Activities in the Coming Reporting Period
The key environmental issues for
the Project in the coming reporting period are expected to be associated with
the construction activities include:
● Generation of dust from construction
works and stockpiles;
● Noise from operating equipment and
machinery on-site;
● Generation of site surface runoffs and
wastewater from activities on-site;
● Sorting, recycling, storage and
disposal of general refuse and construction waste;
● Reuse of treated marine sediments from
excavation works; and
● Management of chemicals and avoidance
of oil spillage on-site.
The implementation of required
mitigation measures by the contractors will be monitored by the ET.
8.3
Monitoring
Schedule for the Coming Reporting Period
A tentative schedule of the
planned environmental monitoring work and the operation phase CWD monitoring in
the next reporting period is provided in Appendix B.
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 new
North Runway was commissioned in November 2022. Following the completion of
reconfiguration works on the Centre Runway, the 3RS was commissioned on 28
November 2024.
The key activities of the Project carried out in the
reporting period are located in reclamation areas and
existing airport island respectively. Works in the reclamation areas included
concourse superstructure works, tunnel works for Automated People Mover (APM)
and Baggage Handling System (BHS) and associated works. Meanwhile, works on the
existing airport island involved Terminal 2 (T2) expansion works, modification
and tunnel works for APM and BHS, utilities works,
road and drainage works and excavation works.
All the monitoring works for construction dust, construction noise,
construction waste and landscape & visual were conducted during the
reporting period in accordance with the Manual.
Monitoring results of construction dust, construction noise and
construction waste did not trigger the corresponding Action and Limit Levels
during the reporting period. No non-conformity was recorded for landscape &
visual monitoring in the reporting period.
The operation phase CWD
monitoring was conducted in April 2025.
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, SkyPier HSF
services to/from Zhuhai/Macau has been suspended until further notice. No HSF
movement between HKIA SkyPier and Zhuhai /Macau was
recorded during the reporting period. Therefore, no deviation was recorded in
the HSF monitoring in the reporting period.
For the implementation of
MTRMP-CAV, the MSS automatically recorded the deviation cases such as speeding
and entering no-entry zone. The ET checked the MSS records to ensure all
deviation cases were followed up. All the concerned captains were reminded by
the contractor’s CTCC representative to comply with the requirements of the
MTRMP-CAV. 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.
