1        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 3RS was commissioned on 28 November 2024.

The summary of construction works programme can be referred to Section 1.4.

The monitoring results were within the corresponding Action and Limit Levels at AR1A in 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 station 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

Following the approval of scaled down construction noise impact monitoring proposal, only monitoring station NM1A is retained to continue construction noise impact monitoring.

Noise monitoring in the form of 30-minute measurements of L_eq, L₁₀, and L₉₀ levels was conducted once per week between 0700 and 1900 on normal weekdays at the representative monitoring station NM1A in the vicinity of noise sensitive receivers in Tung Chung in accordance with the Manual. Table 3.1 describes the details of the monitoring station. Figure 2.1 shows the locations of the monitoring stations.

Table 3.1: Location of Impact Noise Monitoring Station

Monitoring Station	Location	Type of measurement
NM1A	Man Tung Road Park	Free field

3.1        Action and Limit Levels

In accordance with the Manual, baseline noise levels at NM1A was established as presented in the Baseline Monitoring Report. The Action and Limit Levels of the noise monitoring stipulated in the EM&A programme for triggering the relevant investigation and follow-up procedures under the programme are provided in Table 3.2.

NM1A	0700-1900 hours on normal weekdays	When one valid documented complaint is received from any one of the sensitive receivers	75dB(A)(1)

 

3.2        Monitoring Equipment

Noise monitoring was performed using sound level meter at NM1A.  The sound level meters deployed comply with the International Electrotechnical Commission Publications 651:1979 (Type 1) and 804:1985 (Type 1) specifications. Acoustic calibrator was used to check the sound level meters by a known sound pressure level for field measurement.  Details of equipment used in the reporting period are given in Table 3.3.

Table 3.3 : Noise Monitoring Equipment

Equipment	Brand and Model	Last Calibration Date	Calibration Certificate Provided in
Integrated Sound Level Meter	Rion NL-52 (Serial No. 01287679)	2 Oct 2025	Appendix D of Monthly EM&A Report No. 119
Acoustic Calibrator	Casella CEL-120 (Serial No. 2383737	4 Jun 2025	Appendix D of Monthly EM&A Report No. 115

3.3        Monitoring Methodology

3.3.1         Monitoring Procedure

The monitoring procedures involved in the noise monitoring can be summarised as follows:

a.   The sound level meter was set on a tripod at least a height of 1.2m above the ground for free-field measurements at monitoring stations NM1A. A correction of +3dB(A) was applied to the free field measurements.

b.   Parameters such as frequency weighting, time weighting and measurement time were set.

c.   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.

d.   During the monitoring period, L_eq, L₁₀ and L₉₀ were recorded. In addition, site conditions and noise sources were recorded on a record sheet.

e.   Noise measurement results, when higher than the baseline monitoring levels, were corrected with reference to the baseline monitoring levels.

f.    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. Detailed impact monitoring results are presented in Appendix C.

Table 3.4: Summary of Construction Noise Monitoring Results

Monitoring Station	Noise Level Range, dB(A) Leq (30mins)	Limit Level, dB(A) Leq (30mins)
NM1A(1)	61 - 62	75

Note:

(1)     +3dB(A) Façade correction included;

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 the monitoring station in the reporting period.

3.5        Conclusion

As the construction activities were far away from the monitoring station, major source of noise dominating the monitoring station NM1A observed during the construction noise impact monitoring was traffic noise near NM1A 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.

5.1        Action and Limit Levels

8.2        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;

●    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 expanded T2 is being launched in phases, with the first phase of operation commencing on 23 September 2025.

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, pavement works, tunnel works for APM and BHS and associated works. Meanwhile, works on the existing airport island involved T2 expansion works, modification and tunnel works for APM and BHS, utilities works, road and drainage works.

Following the approval of scaled down air quality and construction noise impact monitoring proposal, only monitoring stations AR1A and NM1A are retained to continue air quality and construction noise impact monitoring, respectively.

During the reporting period, all the monitoring works for construction dust, construction noise, construction waste and landscape & visual were conducted in accordance with the Manual, with no exceedances or non-conformities recorded.

Weekly site inspections were carried out by the ET and bi-weekly site inspections were carried out by IEC to audit the implementation of proper environmental pollution control and mitigation measures for the Project. 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 and from Zhuhai and Macau remained suspended with no SkyPier HSFs recorded travelling between HKIA SkyPier and Zhuhai/Macau during the reporting period. 

For the implementation of MTRMP-CAV, marine travel routes records submitted by contractors were reviewed by the ET. No deviation cases were identified. All the concerned contractors were reminded to comply with the requirements outlined in 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.
