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.

This is the 3^rd Construction Phase Monthly EM&A Report for the Project which summarizes the monitoring results and audit findings of the EM&A programme during the reporting period from 1 March 2016 to 31 March 2016.

Key Construction Activities in the Reporting Month

The key construction activities of the Project carried out in the reporting month were related to Contract P560(R) Aviation Fuel Pipeline Diversion Works (Contract P560(R)) which involved site establishment works, construction of temporary concrete footing, mobilization and installation of construction plant, installation of horizontal directional drilling (HDD) casing pipe and setup of site office. Dust suppression measures including wheel washing, watering, covering of excavated materials and establishment of site hoarding have been implemented. Installation of site drainage at the stockpiling area and wastewater treatment facility at the HDD launching site were completed to provide better management of site runoff.

On Sheung Sha Chau Island, topographic survey (including tree and boulder surveys) and installation of safe access facilities (e.g. safety ropes) around the daylighting location were carried out. Measures including prohibiting dumping of waste and effluent as well as tree cutting have been enforced.

EM&A Activities Conducted in the Reporting Period

The monthly EM&A programme was undertaken in accordance with the Updated EM&A Manual of the Project. During the reporting period, the ET conducted thirty-six sets of air quality measurements, twenty-five sets of construction noise measurements, one ecological monitoring on Sheung Sha Chau Island as well as five environmental site inspections, landscape & visual and waste monitoring for the Project’s construction works.

On the implementation of the Marine Travel Routes and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan), the situation has been continuously improved in March 2016 by undertaking of ferry movement monitoring audit. Potential deviations from SkyPier Plan were first identified by the automatic identification system (AIS) monitoring system and notices were issued to concerned ferry operators. Ferry operators had to provide further information and valid reasons for the deviations. The deviation cases were reviewed by ET and checked by IEC against the SkyPier Plan. In March 2016, a total of 822 ferry movements have been monitored and audited. Three deviations of not fully following the diverted route, one deviation of prevailing speed and thirty-five deviations of instantaneous speed were recorded. Investigation results show that the reasons for deviations included strong local wave, giving ways to other vessels and early acceleration before leaving the SCZ or late deceleration before entering the SCZ. The daily movements of all SkyPier high speed ferries (HSFs) in March 2016 were within the maximum daily cap number. The implementation and monitoring requirements stipulated in the SkyPier Plan were fully complied with.

Results of Impact Monitoring

All scheduled 1-hour total suspended particulate (TSP), noise and waste monitoring were completed in the reporting period for the relevant construction activities. No exceedance of the Action/ Limit Levels was recorded.

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. The Manual is available on the Project’s dedicated website (accessible at: http://env.threerunwaysystem.com/en/index.html). 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, all related airside and landside works and associated ancillary and supporting facilities. The existing 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 land-based construction works of the Contract P560(R) Aviation Fuel Pipeline Diversion Works (Contract P560(R)) commenced on 28 December 2015 on the airport island.

All marine works, including the submarine power cable diversion and land formation, will only commence after completion of the gazettal process required under the Foreshore and Sea-bed (Reclamations) Ordinance (FSRO). The overall phasing programme of all construction works and the contract information of Contract P560(R) can be referred to Appendix A of the Construction Phase Monthly EM&A Report No. 1. Any changes/ updates of the construction programme and contract information will be reported in the Monthly EM&A report when necessary.

3.4 Monitoring Methodology

3.4.1 Monitoring Procedure

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

a. The sound level meter was set on a tripod at least a height of 1.2 m above the ground for free-field measurements at monitoring stations NM1A, NM4, NM5 and NM6. A correction of +3 dB(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 1 dB(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, L_eq, L₁₀ and L₉₀ were recorded. In addition, site conditions and noise sources were recorded on a record sheet.

f. Noise measurement results 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.

3.4.2 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.

The sound level meters and acoustic calibrators used in the noise monitoring in the reporting month were the same as those used in the previous reporting month. The calibration records of the sound level meters and acoustic calibrator provided in Appendix B of the Construction Phase Monthly EM&A Report No.2 are still valid.

3.5 Analysis and Interpretation of Monitoring Results

The construction noise monitoring results are summarized in Table 3.4 and the detailed monitoring data are provided in Appendix C.

Table 3.4: Summary of Construction Noise Monitoring Results

Monitoring Station	Noise Level Range, dB(A) L_{eq (30 mins)}	Limit Level, dB(A) L_{eq (30 mins)}

NM3A	57- 61	75
NM4⁽ⁱ⁾	64- 66	70⁽ⁱⁱ⁾
NM5⁽ⁱ⁾	53- 59	75
NM6⁽ⁱ⁾	62- 75	75

Note: (i) +3 dB(A) Façade correction included;

(ii) Reduced to 65 dB(A) during school examination periods.

As the construction activities were small in scale during the reporting period and far away from the monitoring stations, major sources of noise affecting the monitoring stations observed during the construction noise impact monitoring were aircraft noise at NM3A and NM5, aircraft noise and helicopter noise at NM6, road traffic noise at NM1A and school activities at NM4 in this reporting month.

No exceedance of the Action/ Limit Level was recorded at all monitoring stations in the reporting period.

4 Waste Monitoring

4.1 Monitoring Requirements

In accordance with the Updated EM&A Manual, the waste generated from construction activities was audited at least 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. The Action and Limit levels of the construction waste are provided in Table 4.1.

4.2 Waste Management Status

Weekly monitoring of the Project construction works were carried out by the ET on 2, 9, 16, 23 and 30 March 2016 to check and monitor the implementation of proper waste management practices during the construction phase.

For Contract P560(R) Aviation Fuel Pipeline Diversion Works, recommendations were provided during monitoring including the removal of oil stain on ground at the stockpiling area on 23 March 2016 and the provision of spill kit and storage of chemical waste at HDD launching site and stockpiling area on 23 and 30 March 2016. The contractor had followed up with implementation of mitigation measures.

The P560(R) Contractor has implemented on-site waste separation by using different waste receptacles as shown in the photo below. The P560(R) Contractor was advised to properly maintain a recording system, maximize the reuse of C&D materials and properly maintain site tidiness.

Colored waste receptacles provided on-site for waste separation

No waste was disposed off-site during the reporting period. No exceedances of the Action and Limit Levels were recorded in the reporting period.

5 Environmental Site Inspection and Audit

5.1 Weekly Environmental Site Inspection

Weekly site inspections of the construction works were carried out by the ET on 2, 9, 16, 23 and 30 March 2016 to monitor the implementation of proper environmental pollution control and mitigation measures for the Project. Bi-weekly site inspections were also conducted independently by the Project’s Independent Environmental Checker (IEC) on 2, 16 and 30 March 2016. Observations have been recorded in the site inspection checklist and passed to the Contractor together with the appropriate recommended mitigation measures where necessary.

The key observations from site inspection and associated recommendations were related to the requirements of installation of wheel washing facilities, erection of full hoarding for site boundary and provision of drip tray for oil drum. Dust suppression measures including wheel washing, watering of unpaved site area, covering of excavated materials and establishment of site hoarding have been implemented. The installation of wheel washing facilities at HDD launching site and stockpiling area were in progress.

Installation of site drainage at the stockpiling area and wastewater treatment facility at the HDD launching site were completed to provide better management of site runoff. Installation of mud treatment system for HDD works at the HDD launching site was also in progress. The system will be used for handling the wastewater generated during the drilling process to separate solids and wastewater. The treated water will be reused in the drilling process while the residual solid materials will be stockpiled and reused in the reclamation stage of the Project.

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.

5.2 Audit of Route Diversion and Speed Control of the SkyPier High Speed Ferries

The Marine Travel Routes and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan) has been submitted to the Advisory Council on the Environment (ACE) 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 committed to implement the mitigation measure of requiring high speed ferries (HSFs) of SkyPier travelling between HKIA and Zhuhai / Macau to start diverting the route with an associated speed control across an area (i.e. Speed Control Zone (SCZ)) with high Chinese White Dolphin (CWD) abundance by the end of 2015. The route diversion and speed restriction at the SCZ have been implemented since 28 December 2015.

The situation has been improved in March 2016 by undertaking ferry movement monitoring audit. Potential deviations from SkyPier Plan were first identified by the monitoring system and notices were issued to concerned ferry operators. Ferry operators had to provide further information and valid reasons for the deviations. The deviation cases were reviewed by ET and checked by IEC against the SkyPier Plan.

Key audit findings for the SkyPier HSFs travelling to/from Zhuhai and Macau against the requirements of the SkyPier Plan during the reporting period are summarized in Table 5.1. The daily movements of all SkyPier HSFs in March 2016 were within the maximum daily cap number. Status of compliance with annual daily average of 99 movements will be further reviewed in the annual EM&A Report. The implementation and monitoring requirements stipulated in the SkyPier Plan were fully complied with.

In total, 822 ferry movements between HKIA SkyPier and Zhuhai / Macau were recorded in March 2016. All SkyPier HSFs had travelled across the SCZ with prevailing speed under 15 knots, except one that travelled at prevailing speed above 15 knots on 5 March 2016. Automatic Identification System (AIS) data obtained for the concerned HSF showed that the instantaneous speed deviated from 15 knots (around 28 knots) for less than 2 minutes when the HSF was entering the SCZ. After that, the HSF had slowed down to around 11 knots for the remaining 6 minutes of the journey within the SCZ. Notice was issued to concerned ferry operator and investigation was conducted. The concerned HSF captain claimed that he was focused on the sea conditions due to numerous small crafts nearby, which led to late deceleration before entering the SCZ. The ferry operator had conducted an internal meeting with the HSF captains immediately after the event. Further trainings will be arranged for the concerned captain to familiarize the exact locations of the entry and exit points of the SCZ.

Thirty-five deviation cases of instantaneous speeding across the SCZ have been recorded. Investigation results shown that 30 cases were due to local strong water current. The remaining 5 cases were due to early acceleration before leaving the SCZ or late deceleration before entering the SCZ. Further trainings will be arranged for the concerned captains to familiarize the exact locations of the entry and exit points of the SCZ.

Three deviations of HSFs not following the diverted route were recorded on 2 March and 10 March 2016. Notices were sent to the ferry operators and the investigation results are presented as follows:

¡ One case on 2 March 2016: the HSF captain claimed that he decided to travel outside the SCZ temporarily in order to keep a safe distance from an unknown floating object located within the SCZ.

¡ Two cases on 10 March 2016: the concerned HSFs were unable to pass through the entry / exit points of the SCZ due to strong tidal wave and adverse weather conditions.

Data of SkyPier HSF movements to/from Zhuhai and Macau (between 1 and 31 March 2016) is provided in Appendix F. There were 5 HSF movements with no data signals received by the system on 12 March 2016 and these movements are under investigation.

5.3 Ecological Monitoring

In accordance with the Updated EM&A Manual, ecological monitoring shall be undertaken monthly at the HDD daylighting location on Sheung Sha Chau Island to identify and evaluate any impacts with appropriate actions taken as required to address and minimise any adverse impact found. The first monthly ecological monitoring was carried out by the ET on 19 March 2016 on Sheung Sha Chau Island during which topographic survey (including tree and boulder surveys) and installation of safe access facilities (e.g. safety ropes) were carried out by P560(R) Contractor. The monitoring has confirmed that the works conducted on Sheung Sha Chau Island by P560(R) Contractor had not caused direct encroachment or disturbance to the identified egretry area and that the policies of prohibited dumping of waste and tree cutting had been enforced.

A pre-construction egretry survey on Sheung Sha Chau Island conducted between April and July 2015 has indicated that the latest boundary of the egretry had shifted further away from the target daylighting location as shown in the picture below.

The target daylighting location is located at about 120m away from the nearest boundary of Sha Chau Egretry on Sheung Sha Chau Island

6.4 Other EIA / EM&A Issues

6.4.1 On-going and Fore-coming Baseline Monitoring

Baseline monitoring of CWD by vessel surveys, land-based theodolite tracking and passive acoustic monitoring (PAM) are ongoing. The baseline monitoring results will be presented in a separate Baseline Monitoring Report for the marine works.

A baseline water quality monitoring programme is scheduled to be commenced in April 2016.

7 Conclusion and Recommendation

The key construction activities of the Project carried out in the reporting month were related to the Contract P560 Aviation Fuel Pipeline Diversion Works which involved site establishment works, construction of temporary concrete footing, mobilization, installation of construction plants and installation of HDD casing pipe at the HDD launching site. The erection of site hoarding and installation of site drainage system at the stockpile area have been completed. Dust suppression measures including wheeling washing, watering, covering of excavated materials and establishment of site hoarding have been implemented. Construction of site drainage is also in progress for better management of site runoff. Topographic survey (include tree and boulder surveys) and installation of safe access facilities (e.g. safety ropes) were carried out on Sheung Sha Chau Island. Measures including prohibiting dumping of waste and effluent as well as tree cutting have been enforced.

Construction dust, noise and waste monitoring were carried out in the reporting period. No breach of the Action or Limit Levels in relation to the air quality, construction noise and waste monitoring were recorded in the reporting month. Monthly ecological monitoring on Sheung Sha Chau Island and weekly site inspections were carried out during the reporting period by the ET. All site observations made by the ET were recorded in the site inspection checklists and passed to the Contractor together with the recommended follow-up actions.

On the implementation of the SkyPier Plan, the situation has been continuously improved in March 2016 by undertaking ferry movement monitoring audit. All SkyPier HSFs had travelled across the SCZ with prevailing speed under 15 knots, except one that travelled at prevailing speed above 15 knots. Three deviations of not following the diverted route, one deviation of prevailing speed and thirty-five deviations of instantaneous speed were recorded. Investigation results shown that the reasons for deviations included strong local wave, giving ways to other vessels and early acceleration before leaving the SCZ or late deceleration before entering the SCZ. The deviation cases were reviewed by ET and checked by IEC against the SkyPier Plan. The daily movements of all SkyPier HSFs in March 2016 were within the maximum daily cap number. The implementation and monitoring requirements stipulated in the SkyPier Plan were fully complied with.
