Based on information including ET’s observations, records of Maritime Surveillance System (MSS), and contractors’ site records, it is noted that environmental pollution control and mitigation measures were properly implemented and construction activities of the Project in the reporting period did not introduce adverse impacts to the sensitive receivers.

Snapshots of Good Environmental Practices in the Reporting Period

Installation of Energy Efficient Battery System

Use of CIC carbon assessment tool to monitor carbon emissions of on-site construction process

Obtained ISO 50001:2018 Energy Management System Certification

Key examples of good site practices implemented in the Project are highlighted as below:

1.     Replacing traditional diesel generators with an energy efficient battery system for tower crane operation to improve site safety, minimize carbon emissions and noise levels.

2.     A carbon assessment tool established by Construction Industry Council (CIC) was deployed by a contractor to monitor carbon emissions of on-site construction process. Aided by this software application, contractor can measure the carbon footprint of their project and analyse their carbon emissions data in an effective manner.

3.     A 3RS contractor obtained ISO 50001:2018 Energy Management System certification in Dececember 2020 to improve the energy use and enhance the energy consumption performance during the construction operation. 

Summary Findings of the EM&A Programme

The monitoring works for construction dust, construction noise, water quality, construction waste, landscape & visual, and CWD were conducted during the reporting period in accordance with the Manual.

Monitoring results of construction dust, construction noise, construction waste, and CWD monitoring did not trigger the corresponding Action and Limit Levels in the reporting period.

The water quality monitoring results for all parameters, except suspended solids (SS) and chromium, obtained during the reporting period were within the corresponding Action and Limit Levels stipulated in the EM&A programme. Relevant investigation and follow-up actions will be conducted according to the EM&A programme if the corresponding Action and Limit Levels are triggered. For SS and chromium, some testing results triggered the relevant Action or Limit Level, and the corresponding investigations were conducted accordingly. The investigation findings concluded that the case was not related to the Project. To conclude, the construction activities in the reporting period did not introduce adverse impact to all water quality sensitive receivers.

Taking into account the construction works in the reporting period, impact monitoring of air quality, noise, water quality, waste management, landscape & visual, and CWD were carried out in the reporting period.

The EM&A programme also involved weekly site inspections and related auditing conducted by ET for the checking of implementation of required environmental mitigation measures recommended in the approved EIA Report. To promote the environmental awareness and enhance the environmental performance of the contractors, environmental trainings and regular environmental management meetings were conducted during the reporting period which are summarised as below:

   Four skipper trainings provided by ET;

   One dolphin observer training session provided by ET;

   Two environmental briefings on EP and EM&A requirements of the 3RS provided by ET; and

   Fifty-two environmental management meetings for EM&A review with works contracts.

The EM&A programme has been following the recommendations presented in the approved EIA Report and the Manual. 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.

2.1.3      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.

2.2      Noise Monitoring

Impact noise monitoring was conducted at four representative monitoring stations once per week during 0700 and 1900 in the reporting period. The locations of monitoring stations are described in Table 2.4 and presented in Figure 2.1.

2.2.3      Conclusion

Major sources of noise dominating the monitoring stations observed during the construction noise impact monitoring were traffic noise near NM1A 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

During the reporting period, water quality monitoring was conducted three days per week, at mid-flood and mid-ebb tides, at a total of 23 water quality monitoring stations, comprising 12 impact (IM) stations, 8 sensitive receiver (SR) stations, and 3 control (C) stations in the vicinity of the water quality sensitive receivers around the existing airport island in accordance with the Manual. The purpose of water quality monitoring at the IM stations is to promptly capture any potential water quality impacts from the Project before the impacts could become apparent at sensitive receivers (represented by the SR stations). Table 2.7 describes the details of the monitoring stations. Figure 2.2 shows the locations of the monitoring stations.

Due to the completion of all marine-based DCM works within December 2020, regular DCM monitoring was proposed to be ceased at all monitoring stations starting within January 2021 and would be resumed if there are marine-based DCM works in the coming future.

Notes:

(1)    With the operation of HKBCF, water quality monitoring at SR1A station was commenced on 25 October 2018.

(2)    Details of selection criteria for the two heavy metals for regular DCM monitoring refer to the Detailed Plan on Deep Cement Mixing available on the dedicated 3RS website (http://env.threerunwaysystem.com/en/ep-submissions.html).  DCM specific water quality monitoring parameters (total alkalinity and heavy metals) were only conducted at C1 to C3, SR2, and IM1 to IM12.

(3)    According to the Baseline Water Quality Monitoring Report, C3 station is not adequately representative as a control station of impact/ SR stations during the flood tide. The control reference has been changed from C3 to SR2 from 1 September 2016 onwards.

(4)    Total alkalinity and heavy metals results are collected at SR2 as a control station for regular DCM monitoring.

(5)    As the access to SR6 was obstructed by the construction activities and temporary structures for Tung Chung New Town Extension, the monitoring location has been relocated to SR6A starting from 8 August 2019.

(6)    The monitoring location for SR8 is subject to further changes due to silt curtain arrangements and the progressive relocation of this seawater intake.

2.3.1      Action and Limit Levels

The Action and Limit Levels for general water quality monitoring and regular DCM monitoring stipulated in the EM&A programme for triggering the relevant investigation and follow-up procedures under the programme are presented in Table 2.8.

2.3.3      Conclusion

In the reporting period, it is noted that most monitoring results were within their corresponding Action and Limit Levels, while only a minor number of results triggered their corresponding Action or Limit Level, and investigations were conducted accordingly. Based on the findings presented in Construction Phase Monthly EM&A Report Nos. 58 and 60, all cases that triggered the corresponding Action or Limit Level were not related to the Project. Hence, the Project did not introduce adverse impact to all water quality sensitive receivers. All required actions under the Event and Action Plan were followed.

Nevertheless, the non-project related triggers were attended to and initiated corresponding action and measures. As part of the EM&A programme, the construction methods and mitigation measures for water quality will continue to be monitored and opportunities for further enhancement will continue to be explored and implemented where possible, to strive for better protection of water quality and the marine environment.

In the meantime, the contractors were reminded to implement and maintain all mitigation measures during weekly site inspections and regular environmental management meetings. These include maintaining mitigation measures properly for reclamation works including DCM works, marine filling, seawall construction, and bored piling for approach lights as recommended in the Manual.

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.

2.4.1      Action and Limit Levels

The Action and Limit Levels of the construction waste are provided in Table 2.15.

2.4.2      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 had 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 B.

Based on updated contractors’ information, summary of construction waste generated in the reporting period is presented in Table 2.16. Proactive measures have been undertaken during the re-configuration of T2 building.  The contractor has 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 contractor, and ET and IEC have carried out site visits to recyclers’ facilities to review recycling process.  Recycling materials before leaving the site are weighted by a weight bridge and monitored by CCTV system. Dedicated areas for sorting of materials are established on site. Recyclable materials such as steel, reinforcement bar, structural steel, aluminium, copper, other metals and glass are sorted on-site and transported off-site for recycling. ET and IEC have carried out site audits regularly and reviewed the trip ticket system.

3.      C&D materials not suitable for reuse on-site, including asphalt waste and sediment slurry, were transferred to public fill during the 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.

2.4.3           Marine Sediment Management

Marine sediment is managed according to the EIA Report, Updated EM&A Manual and Waste Management Plan of the Project. The sampling process, 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.

Sampling works for marine sediment generated from the reclaimed land area was on-going during the reporting period. The details of the marine sediment sampling, treatment and backfilling will be reported in the subsequent EM&A Reports upon completion.

2.5      Chinese White Dolphin Monitoring

CWD monitoring was conducted by vessel line transect survey at a frequency of two full surveys per month, supplemented by land-based theodolite tracking survey and PAM. The frequency of the land-based theodolite tracking survey during the construction phase was one day per month at both Sha Chau (SC) and Lung Kwu Chau (LKC) stations, as stipulated in the Manual. 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 conducted from October to December 2020 are shown in Figure 2.3, whilst the land-based theodolite tracking survey stations are described in Table 2.17 and depicted in Figure 2.4. The location of the PAM device is shown in Figure 2.10.

2.5.2      Summary of Monitoring Results

2.5.2.1            Vessel Line Transect Survey

Survey Effort

During the October to December 2020 reporting period, 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 1,350 km of survey effort was collected from these surveys, with around 85.9% 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 October to December 2020, there were a total of 45 sightings of CWDs, with 137 dolphins sighted (Table 2.19). Amongst these sightings, 43 sightings with 135 dolphins were recorded during on-effort searches under favourable weather condition.

When breaking down the sightings by survey areas, 2 sightings with 2 dolphins were recorded in NWL, 2 sightings with 4 dolphins were recorded on AW transects, 27 sightings with 88 dolphins were recorded in WL, while 14 sightings with 43 dolphins were recorded in SWL during the current reporting period. No CWD was sighted in NEL survey area.

Compared with the last quarter (i.e. July to September 2020), the total number of CWD sightings slightly increased by a few, but the total number of dolphins dropped by 22%. The drop in terms of number of dolphins was mainly attributed by the decline of the number of dolphins in WL by 29% during the reporting period.

Compared with the same quarter of last year (i.e. October to December 2019), there is an increase in terms of both the total number of CWD sightings and the total number of dolphins by 18% and 25% respectively, contributed by the increase in sightings and dolphins in WL and SWL survey areas. However, there is a significant decline in both the number of sightings and the number of dolphins in NWL by 78% and 89% respectively.

Table 2.19 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 October to December 2020 is illustrated in Figure 2.5. In NWL including AW transects, all the CWD sightings were recorded at the southwestern part of the survey area with two sightings located west to the existing Hong Kong International Airport, while another two sightings located between Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road and the north Lantau coast near Sham Wat Wan. In WL, CWD sightings scattered amongst the survey area with the majority clustered near Peaked Hill and Yi O. In SWL, most of the dolphin sightings were recorded in the waters around Fan Lau and some sightings were scattered around the Soko Islands. No CWD sightings were recorded in NEL survey area. Details of the sighting data are presented in Appendix C.

Encounter Rate

The dolphin encounter rates for the number of on-effort dolphin sightings per 100 km survey effort (STG) and for the total on-effort number of dolphins per 100 km survey effort (ANI) in the whole survey area (i.e. NEL, NWL, AW, WL and SWL) for October, November and December 2020 are summarised in Table 2.20.

In this reporting period, both the running quarterly STG and ANI increased from October to December 2020. No Action Level for CWD monitoring was triggered during the reporting period. For the monthly ANI, however, there was a significant drop from 17.80 in October to 7.19 in December 2020.

Compared with the previous reporting period (i.e. July to September 2020), the running quarterly STG remained relatively steady while the running quarterly ANI became lower. While comparing with the same quarter of last year (i.e. October to December 2019), both the running quarterly STG and ANI increased, from 2.80 to 3.71 and from 8.18 to 11.64 respectively. Encounter rates for these periods are summarised in Table 2.20 and graphical presentation is provided in Appendix C.

Group Size

Between October and December 2020, the group size of CWD sightings ranged from 1 to 15 dolphins. The average group size of CWDs was 3.0 dolphins per group, which is smaller than that of the last quarter (4.2 dolphins per group). The average group size of CWDs in this reporting quarter is slightly larger than that of the same quarter of last year (2.9 dolphins per group).

In this reporting quarter, the number of CWD sightings with medium group size (i.e. 3-9 dolphins) was slightly higher than that with small group size (i.e. 1-2 dolphins). There was only one CWD sighting with large group size (i.e. 10 or more dolphins) recorded in this reporting period.

The majority of the medium sized dolphin groups were recorded over the entire WL survey area and also in SWL near Fan Lau. All sightings recorded at the southwestern part of NWL survey area and also around the Soko Islands in SWL were small sized groups. The only CWD sighting with large group size was recorded at Fan Lau in SWL survey area. Sighting locations of CWD groups with different group sizes are depicted in Figure 2.6.

Figure 2.6: Sighting Locations of Chinese White Dolphins with Different Group Sizes

Remarks: (1) Please note that there are 45 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.

Activities and Association with Fishing Boats

From October to December 2020, four sightings of CWDs were recorded with feeding activities.  Amongst these sightings, one was observed in association with operating gillnetter in AW.

The number of sightings with feeding recorded in the current reporting period is lower than that in the previous reporting period (i.e. 10 sightings involved feeding activities between July and September 2020). The number of CWD sightings with feeding activities is the same as that in the same quarter of last year (i.e. 4 sightings between October and December 2019).

The sighting locations of CWDs engaged in different behaviour during the current reporting period are illustrated in Figure 2.7.

Figure 2.7: Sighting Locations of Chinese White Dolphins Engaged in Different Behaviours

Remarks: Marine park excludes land area and the landward boundary generally follows the high water mark along the coastline.


Mother-calf Pairs

From October to December 2020, seven sightings of CWDs were recorded with the presence of mother-and-unspotted calf or mother-and-unspotted juvenile pairs, which is fewer than that recorded in the previous reporting quarter (i.e. 11 sightings between July and September 2020). The number is higher than that recorded in the same quarter of last year (i.e. three sightings between October and December 2019). All these seven sightings were recorded in WL.

The locations of CWD sightings with the presence of mother-and-calf and/or mother-and-unspotted juvenile pairs are shown in Figure 2.8.

Photo Identification

Between October and December 2020, a total number of 45 different CWD individuals were identified altogether for 81 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 45 different CWD individuals, 21 animals (i.e. SLMM003, SLMM007, SLMM010, SLMM012, SLMM014, SLMM023, SLMM025, SLMM035, SLMM037, SLMM049, SLMM052, WLMM007, WLMM028, WLMM060, WLMM070, WLMM071, WLMM073, WLMM079, WLMM114, WLMM147 and WLMM150) were sighted for more than once.

Ten individuals including SLMM003, SLMM010, SLMM023, SLMM037, SLMM049, WLMM007, WLMM028, WLMM070, WLMM073 and WLMM114 were re-sighted in different survey areas during this reporting period. All cross-area movements were between WL and SWL survey areas except that by SLMM010, the most frequently re-sighted individual in this reporting quarter which has been encountered in NWL, WL and SWL survey areas altogether for six times. The number of CWD individuals re-sighted more than once and the number of CWD individuals showing cross-area movement in the current reporting period are both lower than those of the previous reporting quarter from July to September 2020 (25 and 11 individuals respectively).

A summary of photo identification works is presented in Table 2.21. Representative photos of the 45 identified individuals and figures depicting the sighting locations of the aforementioned 21 re-sighted individuals recorded in this reporting period are presented Appendix C.

2.5.2.2            Land-based Theodolite Tracking Survey

Survey Effort

Between October and December 2020, a total of six days of land-based theodolite tracking survey effort were completed, including three days on Lung Kwu Chau and three days on Sha Chau. In total, six CWD groups were tracked from the Lung Kwu Chau station while no CWD groups were tracked from the Sha Chau station, with an overall 0.17 CWD groups sighted per survey hour.

Information on survey effort and CWD groups sighted during land-based theodolite tracking surveys are presented in Table 2.22. Details on the survey effort and CWD groups tracked are presented in Appendix C. The first sighting locations of CWD groups tracked between October and December 2020 are shown in Figure 2.9.

Remark: Marine park excludes land area and the landward boundary generally follows the high water mark along the coastline.

2.5.2.3            Progress Update on PAM

An Ecological Acoustic Recorder (EAR) has been deployed and positioned to the south of Sha Chau Island inside the SCLKCMP (Figure 2.10) with 20% duty cycle, while PAM data from the EAR intends to supplement the detection of CWD presence in the south Sha Chau area that are not recorded visually by the land-based theodolite tracking survey and to coincide the theodolite data when there is sighting from the land-based station at Sha Chau. In this reporting period, the EAR has been retrieved on 22 October and 3 December 2020 for data collection and subsequently redeployed. The EAR will be deployed for about 4 weeks and retrieved in early January 2021 for annual data analysis, and replaced by F-POD/C-POD for deployment at the same monitoring location with effective from January 2021. As the period of data collection and analysis takes more than four months, PAM results could not be reported in quarterly intervals but report for supplementing the annual CWD monitoring analysis.

2.5.2.4            Site Audit for CWD-related Mitigation Measures

During the reporting period, silt curtains were in place by the contractors for marine filling works (similar to the previous reporting period), in which dolphin observers were deployed by each contractor in accordance with the Marine Mammal Watching Plan (MMWP). Teams of at least two dolphin observers were deployed at 3 to 7 dolphin observation stations by the contractors for continuous monitoring of the DEZ by all contractors for DCM works, seawall construction and bored piling for approach lights in accordance with the DEZ Plan. Trainings for the proposed dolphin observers on the implementation of MMWP and DEZ monitoring were provided by the ET prior to the aforementioned works, with a cumulative total of 703 individuals being trained and the training records were kept by the ET. From the contractors’ MMWP observation records and DEZ monitoring records, no dolphin or other marine mammals were observed within or around the silt curtains or the DEZ in this reporting period. The contractors’ records were also audited by the ET during site inspection.

Audits of acoustic decoupling for construction vessels were carried out during weekly site inspection and summarised in Section 2.6. 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 were carried out on a weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures for the Project. Bi-weekly site inspections were also conducted by the IEC. Besides, ad-hoc site inspections were 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 are highlighted as below:

1.     Replacing traditional diesel generators with an energy efficient battery system for tower crane operation to improve site safety, minimize carbon emissions and noise levels.

2.     A carbon assessment tool established by Construction Industry Council (CIC) was deployed by a contractor to monitor carbon emissions of on-site construction process. Aided by this software application, contractor can measure the carbon footprint of their project and analyse their carbon emissions data in an effective manner.

3.     A 3RS contractor obtained ISO 50001:2018 Energy Management System certification in December 2020 to improve the energy use and enhance the energy consumption performance during the construction operation. 

Installation of Energy Efficient Battery System

Use of CIC carbon assessment tool to monitor carbon emissions of on-site construction process

Obtained certification of ISO 50001:2018 Energy Management System Standard

Besides, advice were 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.

2.6.1           Landscape and Visual Mitigation Measures

Implementation of applicable landscape and visual mitigation measures (reference to the environmental protection measures CM1 – CM10 in Appendix B) is monitored regularly in accordance with the Manual. The implementation status of the environmental protection measures is summarised in Table 2.23. For trees which were managed under the Project during the reporting period, relevant measures have been implemented by Contracts 3302, 3503, 3602 and 3801. Contracts 3508 and 3802 would begin to undertake tree management measures subject to the handover of site area (Contract 3508: Q2 2021 (tentative); Contract 3802: to be confirmed). Those trees which were within the Project boundary yet to be taken care by existing 3RS Contractors during the reporting period were managed by AAHK. The total number of retained trees, transplanted trees and to-be-transplanted trees under the management of Project are summarized in Table 2.24.

The total number of retained trees of the Project as of December 2020 was 118. Compared to 147 retained trees reported in the previous reporting quarter, the change in number was due to the following reasons:

·         2 nos. of trees near Airport North Interchange and 1 no. of tree in Area 3801/13 were damaged due to adverse weather from typhoon Mangkhut in September 2018 and typhoon Higos in August 2020 respectively, and subsequently removed by the Contractor in Aug 2020 (-3 nos.);

·         Some of the Contractor’s initial tree survey areas which recently confirmed not to be works areas and therefore excluded from the Project. Trees located in those areas were removed from the retained tree list under the Project (-27 nos.); and

·         ET and Contractor’s recent on-site inspections confirmed that the status of 1 no. of tree near the Airport North Interchange should be retained tree (+1 no.).

Table 2.25 lists the affected tree ID together with the reasons for change of retained tree status of the Project. 

A total of six trees under Contractor 3503 (i.e. T812, T814, T815, T829, T830 and T831) were transplanted during the reporting quarter. Therefore, the cumulative total number of transplanted trees of the Project has been increased from 8 from previous reporting quarter to 14. The summary of transplanted trees is shown in Table 2.26. Photos of the transplanted trees are presented in Table 2.27 and the locations of newly transplanted trees during the reporting period are presented in Figure 2.11.

2.6.2           Land Contamination Assessment

The Supplementary CAP was submitted to EPD pursuant to EP Condition 2.20. The CARs for Golf Course and T2 Emergency Power Supply System Nos.1 (Volumes 1 and 2), 2, 3, and 5 and No. 4 were submitted to EPD in accordance with EP Condition 1.9 and the Supplementary CAP in which no land contamination issues were identified. EPD has issued no further comment for all the CARs and required ET to submit additional photos for sides and bottom of some of sampling points after the removal of pipelines to reaffirm no leakage from the pipelines concerned. Afterwards, the potential land contamination concern of two concerned systems will be closed.

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.

2.7      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.

Due to the COVID-19 pandemic, all SkyPier HSF services have been suspended from 25 March 2020 until further notice. Two special ferry movements between HKIA SkyPier and Macau were arranged by the ferry operator and were audited in the reporting period. The summary of the SkyPier Plan monitoring result is presented in Graph 1. Besides, limited HSF services from other destination were also provided starting from 28 October 2020.

The daily movements of all SkyPier HSFs, including those not using the diverted route, in the reporting period ranged between 0 and 3, which fell within the maximum daily cap number of 125.

The average speeds of all HSFs travelling through the Speed Control Zone (SCZ) ranged from 10.8 to 11.0 knots. All HSFs travelled through the SCZ with average speed within 15 knots in compliance with the SkyPier Plan.

Graph 1: Summary of SkyPier High Speed Ferries Monitoring Results

In addition, the dolphin habitat index was reviewed based on AFCD latest marine mammals monitoring report findings and historical dolphin density records, and the grids for dolphin hotspot remain unchanged. AAHK will continue to implement the SkyPier HSF route diversion and speed restriction according to the approved SkyPier Plan.

2.8      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 contractor’s Marine Traffic Control Centre (MTCC) representatives, all the concerned captains were reminded to comply with the requirements of the MTRMP-CAV. 

A total of 4 skipper training workshops were held by ET during the reporting period and 16 concerned captains of construction vessels associated with the 3RS contracts were trained to familiarise them with the predefined routes, general education on local cetaceans, guidelines for avoiding adverse water quality impact, the required environmental practices / measures while operating construction and associated vessels under the Project, and guidelines for operating vessels safely in the presence of CWDs. Another 10 skipper training workshops were held with 18 captains by contractors’ Environmental Officers and competency tests were conducted subsequently with the trained captains by ET.

2.9     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.

A complaint was received regarding solid waste and suspected open burning at the project area

Investigation was conducted by ET in accordance with the Manual and the Complaint Management Plan of the Project. The ET identified the potential related 3RS contractors and requested them for information regarding the complaint. Based on information provided by the contractors, no open burning was conducted within their respective construction sites. Besides, general waste was observed properly handled on site and toilets were cleaned by the workers regularly. Before formally receiving the complaint on 6 October 2020, IEC had conducted an ad-hoc site inspection in the alleged area on 30 September 2020. ET had also conducted an on-site investigation with IEC and contractor representatives on 5 October 2020. In both inspections, no opening burning, white smoke, or poor hygiene caused by storage of solid waste on site was observed. The security guards at the western pier and Environmental Officers from the potential related contractors all reported no white smoke was observed at the alleged area on 30 September 2020. Furthermore, the ET checked the construction vessels of all potential related contractors and confirmed no open burning or maintenance works were carried out on the construction vessels on 30 September 2020. Nevertheless, the ET reminded all contractors to continue with the proper handling of general waste produced from the construction site including collection and disposal.
