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 100th 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 30 April 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 are located in reclamation areas and existing airport island respectively. Works in the reclamation areas included land improvement works, filling works, pavement works, concourse superstructure works, tunnel works for Automated People Mover (APM) and Baggage Handling System (BHS) and associated works. Land-based works on existing airport island involved Terminal 2 (T2) expansion works, modification and tunnel works for APM and BHS, utilities works, road and drainage works, excavation works, and 132kV cable laying works.

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

Notes:
(1) +3dB(A) 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. 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 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
The construction phase water quality impact monitoring was carried out according to Section 5.1.8 of the Updated EM&A Manual. With the completion of land formation works including seawall construction and all marine filling works in the first quarter of 2023, termination of the construction phase water quality impact monitoring was proposed to EPD with approval granted on 30 October 2023. The water quality impact monitoring was terminated after 31 October 2023.
A post-construction phase water quality monitoring exercise was 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.

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.

Chinese White Dolphin Monitoring
In accordance with the Manual, CWD monitoring by small vessel line-transect survey should be conducted during post-construction phase. The small vessel line-transect survey should be conducted at a frequency of two full surveys per month as stipulated in the Manual.
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 post-construction 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.
As mentioned in Section 6.1, 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.
6.2.2
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 5, 10, 12, 15, 17, 18, 23 and 26 April 2024 covering all transects in NEL, NWL, AW, WL and SWL survey areas for twice.
A total of around 451.30 km of survey effort was collected from these surveys and around 413.86 km 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, 13 sightings with 43 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. All CWD sightings were recorded in WL where most of the CWD sightings was recorded around the waters between Yi O and Fan Lau. There was no CWD sighting recorded in NEL, NWL and SWL during the reporting period.
Figure 6.2: Sightings Distribution of Chinese White Dolphins
Remarks: (1) Please note that there is 13 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, 13 groups of 43 dolphins in total were sighted, and the average group size of CWDs was 3.3 dolphins per group. The number of small group size (i.e., 1-2) and median group size (i.e., 3-9) of the CWD sightings are relatively similar and no CWD sighting with large group size (i.e. 10 or more dolphins) was recorded in WL.
Activities and Association with Fishing Boats
There was no CWD sightings recorded engaging in foraging activities in the current reporting period in WL survey areas. No sighting was observed in association with boats.
Mother-calf Pair
In this reporting period, there was one sighting recorded with the presence of mother-and-unspotted juvenile pair(s) recorded in WL.
6.3.2
Photo Identification
In the current reporting period, a total number of 27 different CWD individuals were identified for totally 31 times. A summary of photo identification works is presented in Table 6.2. Representative photos of these individuals are given in Appendix C.

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

Audit
of SkyPier High Speed Ferries
The Marine Travel Routes and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan) was submitted to the Advisory Council on the Environment for comment and subsequently submitted to and approved by EPD in November 2015 under EP Condition 2.10. The approved SkyPier Plan is available on the dedicated website of the Project. In the SkyPier Plan, AAHK has committed to implement the mitigation measure of requiring HSFs of SkyPier travelling between HKIA and Zhuhai / Macau to start diverting the route with associated speed control across the area, i.e. Speed Control Zone (SCZ), with high CWD abundance. The route diversion and speed restriction at the SCZ have been implemented since 28 December 2015.
Key audit findings for the SkyPier HSF travelling to/from Macau against the requirements of the SkyPier Plan during the reporting period are summarised in Table 7.7. The daily movement of all SkyPier HSFs, including those not using the diverted route, in this reporting period (i.e. 40 to 54 daily movements) were within the maximum daily cap of 125 daily movements. Status of compliance with the annual daily average of 99 movements will be further reviewed in the Annual EM&A Report.
In total, 25 ferry movements between HKIA SkyPier and Macau were recorded in April 2024 and the data are presented in Appendix F. The time spent by the SkyPier HSF travelling through the SCZ in April 2024 was presented in Figure 7.1. It will take 9.6 minutes to travel through the SCZ when the SkyPier HSFs adopt the maximum allowable speed of 15 knots within the SCZ. Figure 7.1 shows that all the SkyPier HSF spent more than 9.6 minutes to travel through the SCZ.

Conclusion and Recommendation
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.
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 land improvement works, filling works, pavement works, concourse superstructure works, tunnel works for APM and BHS and associated works. Land-based works on existing airport island involved T2 expansion works, modification and tunnel works for APM and BHS, utilities works, road and drainage works, excavation works, and 132kV cable laying 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.
A post-construction phase CWD monitoring by vessel line transect survey was conducted following the same methodology as adopted in construction phase monitoring in accordance with the Manual.
Weekly site inspections of the construction works were carried out by the ET to audit the implementation of proper environmental pollution control and mitigation measures for the Project. Bi-weekly site inspections were also conducted by the IEC. Site inspection findings were recorded in the site inspection checklists and provided to the contractors to follow up.
On the implementation of the SkyPier Plan, the daily movements of all SkyPier HSFs in the reporting period, including those not using the diverted route, were in the range of 40 to 54 daily movements, which are within the maximum daily cap of 125 daily movements. A total of 25 HSFs movements under the SkyPier Plan were recorded in the reporting period. The average speed of all HSFs travelling through the SCZ ranged from 11.7 to 13.3 knots. All HSFs travelled through the SCZ with average speed under 15 knots 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.
On the implementation of MTRMP-CAV, the MSS automatically recorded the deviation case such as speeding, and entering no entry zone. ET conducted checking to ensure the MSS records all deviation cases accurately. Deviations including speeding within the works area and entering no entry zone 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.
