Executive summary

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 106th 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 October 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.

2.3        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 the Monthly EM&A Report No. 103 and the calibration certificates of portable direct reading dust meters listed in Table 2.3 are valid in the reporting period.

The monitoring results were within the corresponding Action and Limit Levels at all monitoring stations 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 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.

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

 Notes:

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

(2)    The limit level will be reduced to 65dB(A) during school examination periods at NM4. School examination took place from 21 to 25 October 2024 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.

5.1        Action and Limit Levels

The Action and Limit Levels of the construction waste are provided in Table 5.1.

5.2        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.

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.

5.3        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 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 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.

6        Chinese White Dolphin Monitoring

In accordance with the Manual, CWD monitoring by small vessel line-transect survey should be conducted during the post-construction phase, with a frequency of two full surveys per month.

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 7, 8, 10, 15, 17, 18, 22 and 24 October 2024 covering all transects in NEL, NWL, AW, WL and SWL survey areas for twice.

A total of around 453.74 km of survey effort was collected from these surveys and around 379.51 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, eight sightings with 18 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, CWD sightings were scattered in the waters near Tai O and Peaked Hill. In SWL, CWD sightings were scattered in waters between Fan Lau and Lo Kei Wan. There was no CWD sighting recorded in NWL and NEL during the reporting period.

Figure 6.2: Sightings Distribution of Chinese White Dolphins

Remarks: (1) Please note that there are eight 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, 8 groups of 18 dolphins in total were sighted, and the average group size of CWDs was 2.3 dolphins per group. Over half of the CWD sightings were having small group size (i.e. 1-2 dolphins) and no CWD sightings with large group size (i.e. 10 or more dolphins) were recorded in the current reporting period.

Activities and Association with Fishing Boats

There were three CWD sightings recorded engaging in foraging activities in WL and SWL survey areas during the current reporting period. Amongst these sightings, there was one sighting observed in association with operating gillnetter in SWL.

Mother-calf Pair

In this reporting period, there were no sightings recorded with the presence of mother-and-unspotted calf and/or mother-and-unspotted juvenile pair(s).

6.3.2         Photo Identification

In the current reporting period, a total number of nine different CWD individuals were identified for totally 11 times. A summary of photo identification works is presented in Table 6.2. Representative photos of these individuals are given in Appendix C.

7        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 Supplementary CAP was submitted to EPD pursuant to EP Condition 2.20. The CARs for Golf Course and T2 Emergency Power Supply Systems (EPSS) were submitted to EPD in accordance with EP Condition 1.9 and the Supplementary CAP in which no land contamination issues were identified. EPD issued no further comment for aforesaid CARs. No leakage was found after the removal of underground fuel pipelines of T2 EPSS and all required additional photos have been submitted to EPD.

According to the approved supplementary CAP, there are 3 remaining locations where site re-appraisal / additional site investigation are proposed. The site re-appraisal summary report for Fire Training Facility was submitted and accepted by EPD on 20 December 2023. The status of site re-appraisal/ additional site investigation of the 2 remaining locations (Fuel Tank Room to the west of CAD Antenna Farm and Airside Petrol Filling Station) shall be further updated upon latest development programme is available.

7.4        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. 55 to 66 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.

For October 2024, a total of 23 ferry movements between HKIA SkyPier and Macau were recorded and the data are presented in Appendix F. The time spent by the SkyPier HSF travelling through the SCZ in October 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.

One ferry was recorded with enter / leave the SCZ not through gate access points on 2 October 2024. ET’s investigation found that the minor route deviation was due to strong tidal wave and current.

Figure 7.1: Duration of the SkyPier HSFs travelling through the SCZ for October 2024   

Note: Data above the red line indicated that the time spent by the SkyPier HSFs travelling through the SCZ is more than 9.6 minutes, which is in compliance with the SkyPier Plan.

7.5        Audit of Construction and Associated Vessels

The updated MTRMP-CAV was approved by EPD on 31 May 2022 under EP Condition 2.9. The approved Plan is available on the dedicated website of the Project.

ET carried out the following actions during the reporting period:

·         One skipper training session was held for contractor to familiarize them with the predefined routes; general education on local cetaceans; guidelines for avoiding adverse water quality impact; the required environmental practices / measures while operation construction and associated vessels under the Project; and guidelines for operating vessels safely in the presence of CWDs. The list of all trained skippers was properly recorded and maintained by ET.

·         Two skipper training sessions were held by contractor’s Environmental Officer. Competency tests were subsequently conducted with the trained skippers by ET. The list of all trained skippers was properly recorded and maintained by ET.

·         In this reporting period, one skipper was trained by ET and two skippers were trained by contractor’s Environmental Officer. In total, 1934 skippers were trained from August 2016 to October 2024.

·         The MSS automatically recorded deviation cases such as speeding and entering no entry zone. ET conducted checking to ensure the MSS records deviation cases accurately.

·         Deviations such as speeding within the works area and entering no entry zone 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.

7.6        Implementation of Dolphin Exclusion Zone

The DEZ Plan was submitted in accordance with EP Condition 3.1 (v) requirement and Section 10.3 of the Manual and approved in April 2016 by EPD. No DEZ implementation was conducted during the reporting period.

7.9        Analysis and Interpretation of Complaints, Notification of Summons and Status of Prosecutions

7.9.1         Complaints

Three complaints were received during the reporting period.

A complaint regarding dust nuisance at 3RS construction site and muddy trails on public roads was received on 4 October 2024. The case was investigated by ET in accordance with the Manual and the Complaint Management Plan of the Project. ET requested the relevant contractors to provide information regarding the complaint and replies indicated dust suppression measures were implemented and water trucks were also arranged to provide road washing. Nevertheless, during the ET’s site inspections, repeated observations regarding dusty tyre trails at vehicular exit of construction site were recorded.  The relevant contractor was reminded to closely monitor the effectiveness of their wheel washing operation at each vehicular exit to ensure all vehicles are properly washed before leaving the construction site and to minimise dust nuisance at public roads; and to provide refresher trainings to their frontline staff and vehicle drivers to avoid recurrence of the malpractices. Hence, the case was considered closed.

The other two cases are under investigation and findings will be reported in the next Monthly EM&A Report.
