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 33rd Construction Phase Quarterly 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 January 2024 to 31 March 2024.
During the reporting period, the project is in the Interim Two Runway System (I-2RS) stage, in which the new North Runway and the associated taxiway and facilities were operated together with the South Runway and existing airport facilities, with the Centre Runway closed down for modification works.
Key Activities in the Reporting Period
The key activities of the Project carried out in the reporting period included reclamation areas and existing airport island respectively. Works in the reclamation areas included rock armour laying works, land improvement works and filling works, pavement works, Terminal 2 Concourse superstructure works, tunnel work for Automated People Mover (APM) and Baggage Handling System (BHS) and associated works. Land-based works on existing airport island involved Terminal 2 expansion works, modification and tunnel work for APM and BHS, utilities works, road and drainage works, demolition, piling, excavation works and 132kV cable laying works.
EM&A Activities Conducted in the Reporting Period
The EM&A programme was undertaken in accordance with the Manual of the Project. Summary of the monitoring activities during this reporting period is presented as below:

Conclusion
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. As the sensitive receivers were far away from the construction activities, with the implementation of noise control measures, there was no adverse impact at the sensitive receivers attributable to the works of the Project.
2.3
Water
Quality Monitoring
In the first quarter of 2023, the land formation works including seawall construction and all marine filling works were completed. As a precautionary measure, construction phase water quality impact monitoring continued until the end of the rainy season. Subsequently, a proposal for terminating the general impact water quality monitoring during the construction phase was submitted to the EPD and received approval on 30 October 2023. The water quality impact monitoring was terminated after 31 October 2023.
A post-construction phase water quality monitoring exercise was then carried out for four weeks according to Section 5.1.10.1 of the Updated EM&A Manual, in the same manner as the impact monitoring at all impact monitoring stations, sensitive receivers stations and control stations during construction phase, from 14 November 2023 to 9 December 2023. The comparison between the baseline, construction phase and post-construction phase monitoring results will be presented in the Annual EM&A report for 2023 and Final EM&A report.
2.4
Waste Monitoring
In accordance with the Manual, waste generated from construction activities was audited once per week to determine if wastes were 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.

Summary
of Monitoring Results
Weekly monitoring of the Project construction works was carried out by the ET in the reporting period to check and monitor the implementation of proper waste management practices.
Recommendations made by the ET included provision and maintenance of proper chemical waste storage area, as well as handling, segregation, and regular disposal of general refuse. The contractors took actions to implement the recommended measures. Waste management audits were carried out by ET according to the requirements of the Waste Management Plan, updated EM&A Manual and the implementation schedule of the waste management mitigation measures in Appendix B.
Based on updated contractors’ information, summary of construction waste generated in the reporting period is presented in Table 2.8. ET and IEC carried out site audits regularly and reviewed the trip ticket system.
The contractors 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 contractors. 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.

Chinese
White Dolphin Monitoring
The post-construction phase CWD monitoring was conducted by vessel line transect survey at a frequency of two full surveys per month. The vessel survey transects followed the transect lines proposed in the Manual and are consistent with those used in the Agriculture, Fisheries and Conservation Department (AFCD) long-term CWD monitoring programme. The transect locations of CWD monitoring by vessel line transect survey are shown in Figure 2.2.
The post-construction phase CWD monitoring which is conducted by vessel line transect survey at a frequency of two full surveys per month has been commenced since January 2024.
2.5.1
Summary of Monitoring Results
2.5.1.1
Vessel Line Transect Survey
Survey Effort
During the reporting period from January to March 2024, a total of six sets of vessel line transect survey covering all transects in Northeast Lantau (NEL), Northwest Lantau (NWL), Airport West (AW), West Lantau (WL) and Southwest Lantau (SWL) survey areas were conducted at a frequency of twice per month, in each survey area.
A total of around 1,353 km of survey effort was collected from these surveys, with around 92.9% of the total survey effort being conducted under favourable weather condition (i.e. Beaufort Sea State 3 or below with favourable visibility). Details of the survey effort data are presented in Appendix C.
CWD Sighting
From January to March 2024, there were a total of 21 sightings of CWD, with 75 dolphins sighted (Table 2.9). There were 20 sightings and 73 dolphins were recorded during on-effort searches under favourable weather condition.
When breaking down the sightings by survey areas, 18 sightings with a total of 68 dolphins and 2 sightings with a total of 6 dolphins were recorded in, WL and SWL respectively during the current reporting period. One sighting of one dolphin was recorded on AW transect within NWL survey area. No CWD was sighted in NEL survey area.
Compared with the previous quarter (i.e. October to December 2023), the total number of CWD sightings and the total number of the dolphins have decreased by 36% and 24% respectively. There was a notable reduction in dolphin sightings and the number of dolphins in both WL and SWL survey area in the current reporting quarter.
Compared with the same quarter of last year (i.e., January to March 2023), there were notable decrease in both the total number of sightings and the total number of dolphins by 51% and 55% respectively. In WL, there was a decrease in both the number of sightings and number of dolphins by 22% and 31% respectively. On the other hand, there were also significant decrease in both number of sightings and number of dolphins in SWL by 60% and 45% respectively. Moreover, there were significant decrease in both total number of sightings and total number of dolphins to 0 in NWL.
Table 2.9 below shows the comparison of the numbers of sightings and dolphins amongst the current reporting period, last quarter, and the same quarter of last year.

The distribution of CWD sightings recorded from January to March 2024 is illustrated in Figure 2.3. In WL, most CWD sightings were scattered amongst the entire survey area, with the majority scattered at the waters between Tai O and Fan Lau. In SWL, the only two CWD sightings were recorded in waters between Fan Lau and Fan Lau Tung Wan. In NWL, the only sighting was recorded on the Airport West transect. No CWD sightings were recorded in NEL survey area during the reporting period. Details of the sighting data are presented in Appendix C.
Figure 2.3: Sightings Distribution of Chinese White Dolphins from January to March 2024
Remarks: (1) Please note that there are 21 pink circles on the map indicating the sighting locations of CWD. Some of them were very close to each other and therefore appear overlapped on this sighting distribution map. (2) Marine Park excludes land area and the landward boundary generally follows the high water mark along the coastline.
Group Size
Between January to March 2024, the group size of CWD sightings ranged from one to 11 dolphins. The average group size of CWD was 3.57 dolphins per group, which is larger than that of the last quarter (3.00 dolphins per group). The average group size of CWD in this reporting quarter is slightly smaller than that of the same quarter of last year (3.86 dolphins per group).
In this reporting quarter, over half of the CWD sightings were in small group size (i.e., 1-2 dolphins). There was one CWD sighting with large group size (i.e., 10 or more dolphins) recorded in WL near Yi O in this reporting period.
There was no apparent pattern in the distribution of small-sized dolphin groups and medium-sized dolphin groups in all survey areas. Sighting locations of CWD groups with different group sizes are depicted in Figure 2.4.

Some of them were very close to each other and therefore appear overlapped on this sighting distribution map. (2) Marine park excludes land area and the landward boundary generally follows the high water mark along the coastline.
Activities and Association with Fishing Boats
From January to March 2024, six sightings of CWD were recorded with foraging activities. Amongst them, one sighting was observed associated with operating gillnetter in WL.
Sightings with foraging activities recorded in the current reporting period was lower than that in the previous reporting period (i.e., 13 sightings involved foraging activities between October and December 2023). The number of CWD sightings with foraging activities in this reporting period was also significantly lower than that in the same quarter of last year (i.e., 16 sightings between January and March 2023).
The sighting locations of CWDs engaged in different behaviours during the current reporting period are illustrated in Figure 2.5.

Remarks: (1) Marine park excludes land area and the landward boundary generally follows the high water mark along the coastline.
Mother-calf Pairs
From January to March 2024, seven sightings of CWD were recorded with the presence of mother-and-unspotted juvenile pairs and/or mother-and-calf pair, which was higher than that recorded in the previous reporting quarter (i.e., five sightings between October and December 2023). The number of CWD sightings with the presence of mother-calf pairs was lower than that recorded in the same quarter of last year (i.e., nine sightings between January to March 2023).
These seven sightings with the presence of mother-calf pairs recording during the reporting period were all recorded in WL survey area. The locations of CWD sightings with the presence of mother-calf pairs are shown in Figure 2.6.

Remarks: (1) Please note that there are 7 circles on the map indicating the sighting locations of CWD. Some of them were very close to each other and therefore appear overlapped on this sighting distribution map. (2) Marine park excludes land area and the landward boundary generally follows the high water mark along the coastline.
Photo Identification
Between January and March 2024, a total number of 31 different CWD individuals were identified altogether for 55 times. Re-sighting information of CWD individuals provides an initial idea of their range use and apparent connection between different areas of Lantau waters. Amongst these 31 different CWD individuals, 16 animals (i.e., SLMM003, SLMM007, SLMM014, SLMM037, SLMM052, WLMM001, WLMM007, WLMM029, WLMM056, WLMM068, WLMM079, WLMM114, WLMM147, WLMM159, WLMM162 and WLMM192) were sighted for more than once.
Three individuals including SLMM003, WLMM056 and WLMM114 were re-sighted in different survey areas during this reporting period. The most frequently re-sighted individuals in this reporting quarter were SLMM003 which was successfully identified for five times. The numbers of CWD individuals re-sighted more than once was higher than that of the last report reporting period from October to December 2023 while the number of identified individuals showed cross-area movement is in opposite trend (i.e. 12 and 5 CWD individuals respectively).
A summary of photo identification works is presented in Table 2.10. Representative photos of the 31 identified individuals and figures depicting the sighting locations of the aforementioned 3 individuals re-sighted in different survey areas in this reporting period are presented in Appendix C.

2.5.1.2
Site Audit for CWD-related Mitigation Measures
During the reporting period, a dolphin observation station and team of at least two dolphin observers was deployed by the contractors for continuous monitoring of the DEZ for armour rock laying works in accordance with the DEZ Plan. From the contractors’ DEZ monitoring records, no dolphin or other marine mammals were observed within or around the DEZ in this reporting period. The contractor’s records were also audited by the ET during site inspection.
Summary of audits of SkyPier HSFs route diversion and speed control and construction vessel management are presented in Section 2.7 and Section 2.8 respectively.
2.6
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. 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 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 implemented in the project to enhance environmental performance. Key examples implemented in the Project are highlighted as below:
1. Three automatic wheel washing facilities were installed in series by the contractor ensure the vehicle was washed thoroughly, and all dusty materials from its underneath and wheels were removed before leaving the construction site.
2. Automatic drip irrigation system was provided by the contractor to maintain good health condition of the trees.
3. Water spraying was provided at the stockpiling area for dust suppression purposes.

Besides, 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 B.
2.6.1
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 B) was monitored regularly in accordance with the Manual. The implementation status of the environmental protection measures is summarised in Table 2.11. For trees which were managed under the Project during the reporting period, relevant measures (i.e., CM1 – CM9) were implemented by Contracts 3508 and 3801. For CM10, the advanced hydroseeding works around taxiways and runways were partially completed and would resume in next phase. The total number of retained trees, transplanted trees and to-be-transplanted trees under the management of Project are summarized in Table 2.12.
The total number of retained trees of the Project as of March 2024 was 34. Compared to 37 retained trees reported in the previous reporting period, the change in number was due to the following reason:
· 3 nos. of trees under Contract 3801 were handed over to AAHK (-3 nos.).
Table 2.13 lists the affected tree ID together with the reason for change of retained tree status of the Project.
The cumulative total number of transplanted trees of the Project remained unchanged (i.e. 26 nos.) comparing with previous reporting quarter. Details of the summary of transplanted trees are shown in Table 2.14. Photos of the transplanted trees are presented in Table 2.15.
For OM7, the bi-monthly site inspections for 12-month establishment period were undertaken in February and March 2024 during the reporting period.

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.
In total, 64 ferry movements between HKIA SkyPier and Macau were audited in the reporting period. The daily movements of all SkyPier HSFs in the reporting period, including those not using the diverted route, ranged between 40 and 54, which fell within the maximum daily cap number of 125.
The average speed of the HSF travelling through the Speed Control Zone (SCZ) ranged from 10.6 to 13.7 knots. All HSFs travelled through the SCZ with average speed within 15 knots, used diverted route and entered / left SCZ through gate access points in compliance with the SkyPier Plan. The summary of the SkyPier Plan monitoring result is presented in Graph 1.

Audit
of Construction and Associated Vessels
On the implementation of the updated Marine Travel Routes and Management Plan for Construction and Associated Vessels (MTRMP-CAV), the Maritime Surveillance System (MSS) automatically recorded deviation cases such as speeding, entering no entry zone, and not traveling through the designated gates. ET conducted bi-weekly audit of relevant information including AIS data, vessel tracks and other relevant records to ensure sufficient information were provided by the system and the contractors complied with the requirements of the MTRMP-CAV. The contactors submitted 3-month rolling vessel plans for construction vessel activities to AAHK in order to help maintain the number of construction vessels to a practicable minimum. The IEC also performed audit on the compliance of the requirements as part of the EM&A programme.
During the reporting period, deviations including speeding within the works area, entry from non-designated gates, and entering no-entry zones were identified. After investigation by the contractors’ Construction Traffic Control Centre (CTCC) representatives, all the concerned captains were reminded to comply with the requirements of the MTRMP-CAV.
Total seven skipper training workshops were held with nine captains by contractors’ Environmental Officers and competency tests were conducted subsequently with the trained captains by ET.

Conclusion and Recommendation
In the first quarter of 2024, the EM&A programme has been implemented as planned, including 96 sets of air quality measurements, 52 sets of construction noise measurements, 6 complete sets of vessel line transect surveys for post-construction phase CWD monitoring, as well as environmental site inspections and waste monitoring for the Project’s construction works.
The key activities of the Project carried out in the reporting period are located in reclamation area and existing airport island respectively. Works in the reclamation areas included rock armour laying works, land improvement works, filling works, pavement works, Terminal 2 Concourse superstructure works, tunnel works for APM and BHS and associated works. Land-based works on existing airport island involved Terminal 2 expansion works, modification and tunnel works for APM and BHS, utilities works, road and drainage works, demolition, piling, excavation works, and 132kV cable laying works.
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.
Four weeks of post-construction phase water quality monitoring exercise was conducted from 14 November 2023 to 9 December 2023, in the same manner as the impact monitoring at all monitoring stations during the construction phase. The comparison between the baseline, construction phase and post-construction phase monitoring results will be presented in Annual EM&A report for 2023 and Final EM&A report.
Post-construction phase CWD monitoring by vessel line transect survey were conducted following the same methodology as adopted in construction phase monitoring. A total of around 1,353 km of survey effort was collected from these surveys during the reporting period, with around 92.9% of the total survey effort being conducted under favourable weather condition (i.e. Beaufort Sea State 3 or below with favourable visibility) and a total of 20 sightings and with 73 dolphins were recorded during on-effort searches under such favourable weather condition.
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. Site inspection findings were recorded in the site inspection checklists and provided to the contractors to follow up.
In total of 64 HSF movements under the SkyPier Plan were audited in the reporting period. All HSFs were travelled through the SCZ with average speed under 15 knots, used diverted route and entered / left SCZ through gate access points in compliance with the SkyPier Plan. In summary, the ET and IEC audited the HSF movements against the SkyPier Plan and conducted follow up investigations or actions accordingly.
During the reporting period, ET conducted bi-weekly audit of the MSS to ensure the system recorded all deviation cases accurately and the contractors fully complied with the requirements of the MTRMP-CAV.
On the implementation of DEZ Plan, dolphin observers were deployed by the contractor in accordance with the plan. No dolphin or other marine mammals were observed within or around the DEZ in this reporting period. Audits of contractor’s implementation and records were carried out by the ET during site inspection.
In accordance with Condition 2.6 of EP, AAHK has assisted AFCD in taking forward the statutory procedures for the designation of the NLMP. A gazette notice regarding the approved map was published by the Government on 29 September 2023 with a Draft Designation Order and a relevant Executive Council paper was prepared. The designation date (i.e. effective date of the NLMP) shall tie in with the commissioning of the 3RS.
The recommended environmental mitigation measures, as included in the EM&A programme, were effectively implemented during the reporting period. Also, the EM&A programme implemented by the ET has effectively monitored the construction activities and ensured the proper implementation of mitigation measures.
