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 5^th 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 May 2016 to 31 May 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 installation of horizontal directional drilling (HDD) casing and antenna farm structural protection works. Dust suppression measures including wheel washing, watering and covering of excavated materials and establishment of site hoarding have been implemented.

No construction work was carried out on Sheung Sha Chau Island during the ardeid’s breeding season in the reporting month in accordance with the Updated EM&A Manual.

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-three sets of air quality measurements, twenty-three sets of construction noise measurements, as well as four environmental site inspections, landscape & visual and waste monitoring for the Project’s construction works.

On the implementation of the SkyPier Plan, the daily movements of all SkyPier HSFs in May 2016 were within the maximum daily cap number. A total of 837 HSF movements under SkyPier Plan were recorded. All HSFs had travelled through the SCZ with prevailing speed under 15 knots (7.8 to 14.7 knots) in compliance with the SkyPier Plan. There was one case of not fully following the diverted route and investigation results revealed that the case was related to safety/emergency situations. In summary, the ET and IEC have audited the HSF movements against the SkyPier Plan and conducted follow up investigation or actions accordingly.

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.

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. Notably, on 29 April 2016, AAHK received the Chief Executive-in-Council’s approval for draft Chek Lap Kok Outline Zoning Plan, as well as the authorization of the reclamation under the Foreshore and Sea-bed (Reclamations) Ordinance for the expansion of HKIA into a 3RS.

3.4 Monitoring Methodology

3.4.1 Monitoring Procedure

The monitoring procedures 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.

Calibration certificates of the sound level meters and acoustic calibrators used in the noise monitoring are provided in Appendix B.

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 D.

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)}

NM4⁽ⁱ⁾	60- 66	70⁽ⁱⁱ⁾
NM5⁽ⁱ⁾	53- 59	75
NM6⁽ⁱ⁾	66- 74	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 dominating 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 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 was carried out by the ET on 4, 11, 18 and 25 May 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 provision of drip tray for equipment to avoid oil leakage and provision of spill kit on sites on 25 May 2016. The contractor had followed up with implementation of mitigation measures.

The P560(R) Contractor was advised to properly maintain a recording system, maximize the reuse of C&D materials and properly maintain site tidiness.

Based on the updated information, about 46m³ and 5m³excavated materials were produced from the HDD launching site in April and May 2016 respectively. The generated excavated materials were temporarily stored at storage and stockpiling area at Chun Ming Road adjacent to Tradeport Logistic Centre on the airport island. The excavated material will be reused in the Project.

In addition, 1.12 tonnes of general refuse were disposed of to the West New Territories (WENT) Landfill in May 2016. No Construction and Demolition (C&D) material was disposed off-site during the reporting month. 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 inspection of the construction works was carried out by the ET on 4, 11, 18 and 25 May 2016 to monitor the implementation of proper environmental pollution control and mitigation measures for the Project. Site inspections were also conducted independently by the Project’s Independent Environmental Checker (IEC) on 11 and 25 May 2016. Observations have been recorded in the site inspection checklists 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 improvement of efficiency and capacity of wastewater treatment facilities, provision of drip tray for equipment and provision of spill kit on sites. Dust suppression measures including provision of wheel washing facilities, watering of unpaved site area, covering of excavated materials and establishment of site hoarding have been implemented. Improvement of capacity of wastewater treatment facility at the stockpiling site was in-progress to provide better management of site runoff.

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 implementing 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. The route diversion and speed restriction at the SCZ have been implemented since 28 December 2015.

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 May 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.

In total, 837 ferry movements between HKIA SkyPier and Zhuhai / Macau were recorded in May 2016 and the data are presented in Appendix G. The time spent for the SkyPier HSFs travelled through the SCZ in May were presented in Figure 5-1. It will take 9.6 minutes to travel through the SCZ when the SkyPier HSFs adopt the maximum allowed speed of 15-knot within the SCZ. Figure 5-1 shows that all the SkyPier HSFs spent more than 9.6 minutes to travel through the SCZ and the SkyPier HSFs had travelled through the SCZ with prevailing speeds ranging from 7.8 to 14.7 knots.

Figure 5‑1 Duration of the SkyPier HSFs travelled through the SCZ for May 2016

One ferry movement was not strictly following the diverted route as recorded on 16 May 2016. Notice was sent to the ferry operators and the investigation results revealed that they were related to safety / emergency situations presented as follows:

¡ Case on 16 May 2016: HSF captain reported that he had to give way to other vessels for safety reason and was not able to enter the SCZ through the gate access points. Then the HSF returned to the normal route following the SkyPier Plan.

Two HSF movements with no transmission of AIS data received on 30 May 2016 were reported. After investigation, it was found that missing of AIS data for the concerned ferry was due to error of the AIS system. Follow up action will be undertaken with the concerned Ferry Operator.

Two skipper workshops were held on 25 and 26 May 2016 as refresher trainings to ferry captains about the requirements of the SkyPier Plan.
