1 Introduction

1.1 Background

1.1.1 The Hong Kong-Zhuhai-Macao Bridge (HZMB), when completed, will enhance accessibility between the Hong Kong International Airport (HKIA) and the Pearl River Delta (PRD). To capitalise on the HZMB, the Airport Authority Hong Kong (AAHK) is planning to introduce a hassle-free bonded vehicle service between existing HKIA and the PRD West through Hong Kong Boundary Crossing Facilities (HKBCF), similar to the bonded ferry service plying between the HKIA’s SkyPier and nine ports in the PRD, which would substantially strengthen HKIA’s capability in extending its catchment area to PRD West. To meet this demand, the AAHK plans to construct the Intermodal Transfer Terminal (ITT) adjacent to the SkyPier and it is necessary to build a bonded connection between the ITT and the HKBCF to enable intermodal transfer of HKIA’s air passengers to/from the HZMB without the need to go through Hong Kong’s immigration clearance. The provision of land connection between ITT and HKBCF has been proposed by the AAHK.

1.1.2 After thorough considerations, AAHK decided to provide the land connection in the form of a bridge, namely Bonded Vehicular Bridge, to provide a direct and effective linkage between the ITT and the HKBCF (hereafter referred to as the “Project”). The location of the Project is shown in Figure 1.1. AAHK plans that only air transit passengers by bonded vehicles will be permitted to access the area, and no public vehicle will be allowed to access the Bonded Vehicular Bridge.

1.1.3 The Project comprises the following Designated Project (DP) under Part I of Schedule 2 to the Environmental Impact Assessment Ordinance (EIAO).

· Item A.8 - A road or railway bridge more than 100 m in length between abutments; and

· Item C.3(a) - Reclamation works resulting in 5% decrease in cross sectional area calculated on the basis of 0.0 mPD in a sea channel.

1.1.4 An application for an Environmental Impact Assessment (EIA) Study Brief under section 5(1)(a) of the EIAO was submitted on 30 August 2017 with a Project Profile (No. PP-556/2017) for the Project. An EIA Study Brief (No. ESB-302/2017) was issued by Environmental Protection Department (EPD) on 10 October 2017.

1.2 Project Description

1.2.1 The Project site is situated between the HKBCF Island and the HKIA, at the south of the existing SkyPier on the Airport Island. The Bonded Vehicular Bridge serves as a land connection between the HKBCF Island and ITT building next to the SkyPier to be built by AAHK. Part of the bridge is located in the marine area (marine section) and part on the HKBCF Island (land section). Location of the Project site and layout are shown in Figure 1.1. The marine section of the site is situated in a marine area between HKIA and HKBCF Island.

1.2.2 The Bonded Vehicular Bridge serves as a dedicated direct vehicular access connecting the ITT of HKIA and HKBCF Island. The Project scale is anticipated to be small, the bridge’s marine section is approximately 360 m in length, supported by bridge concrete piers. The Bridge’s land section spans over the HKBCF Island with a total length of approximately 210 m. In additional, AAHK incorporates environmental friendly initiatives by using 100% electrical vehicles, hence, there will be no air pollutants emission during operation of the Project.

1.2.3 The construction works of the Project will tentatively commence in 2020 for completion in 2022.

2 Air Quality

2.1 Introduction

2.1.1 Potential air quality impacts arising from the construction and operational phases of the Project were addressed in the EIA Report, no adverse air quality impact from the Project would be anticipated with the implementation of dust suppression measures during construction phase and the provision of electric vehicles to provide hassle-free bonded cross-boundary bus trips during operational phase. No specific air quality monitoring is therefore considered necessary for both construction and operational phases of the Project. Nevertheless, regular site environmental audit is recommended to ensure the implementation of the recommended mitigation measures during construction phase.

2.2 Mitigation Measures

2.2.1 Mitigation measures for construction phase air quality impacts have been recommended in the EIA Report. All the recommended mitigation measures are detailed in the implementation schedule in Appendix B. The Contractor should be responsible for the design and implementation of the mitigation measures.

2.3 Audit Requirements

2.3.1 Regular site inspection and audit at least once per week should be conducted during the construction phase of the Project to ensure the recommended mitigation measures are properly implemented.

3 Noise

3.1 Introduction

3.1.1 Potential noise impacts arising from the construction and operational phases of the Project were assessed in the EIA Report. The assessment results indicated that no adverse noise impact generated from the construction and operation of the Project. No specific noise monitoring is therefore considered necessary for both construction and operational phases. Nevertheless, regular site environmental audit is recommended to ensure the implementation of the recommended mitigation measures during construction phase.

3.2 Mitigation Measures

Construction Phase

3.2.1 Since no existing and planned NSRs which rely on opened windows for ventilation is identified within the assessment area, it is predicted that there will be no adverse noise impact generated from the construction and operation of the Project. Nonetheless, good site practice and the noise control requirements stated in EPD’s "Recommended Pollution Control Clauses for Construction Contracts” were recommended to minimise the potential noise nuisance during construction phase. Details of the recommended good site practices are presented in Appendix B.

3.3 Audit Requirements

3.3.1 Regular site environmental audit at least once per week during the construction phase of the Project should be conducted to ensure good site practices as listed in Appendix B and the noise control requirements stated in EPD’s "Recommended Pollution Control Clauses for Construction Contracts” are implemented properly to further minimise the potential noise nuisance during construction phase of the Project.

4 Water Quality

4.1 Introduction

4.1.1 Potential water quality impacts arising from the construction and operational phases of the Project were identified and assessed in the EIA Report. No adverse water quality impacts from the Project would be expected during the construction and operational phases of the Project. Nevertheless, water quality monitoring and audit is recommended during construction phase to ensure that all the recommended mitigation measures are properly implemented. No monitoring or audit is required during operational phase.

4.1.2 Details of the water quality monitoring and audit programme and the Event and Action Plan are provided below.

4.2 Construction Phase EM&A

Monitoring Parameters

4.2.1 Monitoring for Dissolved Oxygen (DO), Dissolved Oxygen Saturation (DO%), temperature, pH, turbidity, salinity, suspended solid (SS) and water depth should be undertaken at all designated monitoring locations. All parameters should be measured in-situ whereas SS should be determined by the laboratory. DO should be presented in mg/L and in % saturation.

4.2.2 Other relevant data should also be recorded, including monitoring location / position, time, tidal stages, weather conditions and any special phenomena or work underway at the construction site.

Monitoring Schedule and Stations

4.2.3 The proposed water quality monitoring schedule should be submitted to EPD at least two weeks before the first day of the monitoring month. EPD should also be notified immediately for any changes in schedule. The monitoring stations proposed in this section are indicative subject to further review before construction phase. The locations of monitoring stations may change after issuing this Manual. The proposed monitoring locations should be submitted four weeks before commencement of baseline monitoring for EPD approval.

4.2.4 When alternative monitoring locations are proposed, they shall be chosen based on the following criteria:

• close to the sensitive receptors which are directly or likely to be affected;

• for monitoring locations located in the vicinity of the sensitive receptors, care shall be taken to cause minimal disturbance during monitoring;

• two or more control stations which shall be at representative locations of the Project site in its undisturbed condition. Control stations shall be located, as far as practicable, both upstream and downstream of the works area.

4.2.5 It is proposed to monitor the water quality at three locations in the sea channel between the HKIA and the HKBCF (M1, M2 and M3) and two control stations (C1 and C2). As the water flow direction in the sea channel is dominated by the tidal forcing from the northern entrance of the sea channel, impact stations (M1, M2 and M3) are assigned in the sea channel close to the construction site to measure any elevation of pollutant levels (e.g. SS level) due to the Project. Control stations (C1 and C2) are assigned north of the entrance of the sea channel to compare the water quality from potentially impacted sites with the ambient water quality during monitoring. The proposed marine water quality monitoring stations are listed in Table 4.1 and its locations are shown in Appendix C.

Table 4.1 Proposed Marine Water Quality Monitoring Stations for Baseline and Construction Phase Monitoring

Station	Descriptions	Easting	Northing
M1	Impact Station	812423	819635
M2	Impact Station	812630	820068
M3	Impact Station	812670	820400
C1	Control Station – West	812419	820670
C2	Control Station – East	813072	820595

Monitoring Requirements

4.2.6 Baseline, impact and post-construction monitoring shall be conducted. The following requirements should be followed for baseline, impact and post-construction monitoring.

• Measurement should be taken at 3 water depths, namely, 1m below water surface, mid-depth and 1m above sea bed, except where the water depth less that 6m, the mid-depth station may be omitted. Should the water depth be less than 3m, only the mid-depth station will be monitored. The ET should agree with EPD on all the monitoring stations.

• Duplicate in-situ measurements and water samples collected from each independent monitoring event are required for all parameters to ensure a robust statistically interpretable dataset.

• No sampling should be carried out when typhoon signal No. 3 or above or black rainstorm signal is hoisted.

• At each measurement depth, two consecutive measurements would be taken. The probes would be retrieved out of the water after the first measurement and then redeployed for the second measurement. When the difference in value between the first and second measurement of on-site parameters is more than 25% of the value of the first reading, the reading shall be discarded and further readings shall be taken.

Baseline Monitoring

4.2.7 Baseline conditions for marine water quality should be established and agreed with EPD prior to the commencement of works. The purpose of the baseline monitoring is to establish ambient conditions prior to the commencement of the marine construction works and to demonstrate the suitability of the proposed monitoring stations. The baseline monitoring report should be submitted to EPD at least 4 weeks before the commencement of marine works for agreement. The baseline monitoring report should be certified by the ET Leader and verified by IEC before submission to EPD.

4.2.8 The baseline conditions should be established by measuring water quality parameters as specified in Section 4.2.1 and 4.2.2 at the designated monitoring stations as shown in Table 4.1. The measurement depths shall follow those specified in Section 4.2.5. The measurements should be taken at all designated monitoring stations including control station, 3 days per week, at mid-flood and mid-ebb tides, for at least 4 weeks prior to the commencement of marine works. There should not be any marine construction activities in the vicinity of the stations during the baseline monitoring. The interval between 2 sets of monitoring should not be less than 36 hours.

Impact Monitoring

4.2.9 During the marine construction period of the Bonded Vehicular Bridge, impact monitoring should be undertaken 3 days per week, at mid-flood and mid-ebb tides, with sampling/measurement at all designated monitoring stations including control station as specified in Table 4.1. The interval between 2 sets of monitoring should not be less than 36 hours except where there are exceedances of Action and/or Limit levels, in which case the monitoring frequency will be increased. The monitoring parameters and measurement depths shall follow those specified in Section 4.2.1, 4.2.2 and 4.2.5. Duplicate water samples should be taken and analysed.

4.2.10 If the impact monitoring data collected at the monitoring stations (i.e. Stations M1, M2 and M3) indicate that the Action or Limit levels as shown in Table 4.2 are exceeded, analysis should be conducted to identify whether the exceedance is caused by Project activities. If the data analysis results indicate that the exceedance is caused by this Project, appropriate actions including lowering the working rate, or rescheduling of works should be taken and additional mitigation measures should be implemented as necessary.

Post-Construction Monitoring

4.2.11 Upon completion of all marine works, a post-project monitoring should be carried out for 4 weeks in the same manner as the impact monitoring.

Construction Site Audits

4.2.12 Implementation of regular site audits is to ensure that the recommended mitigation measures are to be properly undertaken during construction phase of the Project. It can also provide an effective control of any malpractices and therefore achieve continual improvement of environmental performance on site.

4.2.13 Site audits should include site inspections and compliance audits.

Site Inspections

4.2.14 Site inspections should be carried out by the ET and should be based on the mitigation measures for water pollution control recommended in Appendix B. In the event that the recommended mitigation measures are not fully or properly implemented, deficiency should be recorded and reported to the site management. Suitable actions are to be carried out to:

• investigate the problems and the causes;

• issue action notes to the Contractor which is responsible for the works;

• implement remedial and corrective actions immediately;

• re-inspect the site conditions upon completion of the remedial and corrective actions; and

• record the event and discuss with the Contractor for preventive actions.

Compliance Audits

4.2.15 Monitoring of the treated effluent quality from the Project site is required during the construction phase of the Project. The monitoring should be carried out at the pre-determined discharge point. Compliance audits are to be undertaken to ensure that a valid discharge licence has been issued by EPD prior to the discharge of effluent from the Project site. The monitoring frequency and parameters specified in the discharge licence under WPCO should be fully considered during the monitoring.

4.2.16 The implementation schedule for the recommended water quality mitigation measures is presented in Appendix B.

Monitoring Equipment

4.2.17 The following equipment and facilities should be provided by the ET and used for the monitoring of water quality impacts:

Monitoring Position Equipment

4.2.18 A hand-held or boat-fixed type digital Differential Global Positioning System (DGPS) with way point bearing indication or other equipment instrument of similar accuracy, should be provided and used during water quality monitoring to ensure the monitoring vessel is at the correct location before taking measurements. DGPS or the equivalent instrument, calibrated at appropriate checkpoint (e.g. Quarry Bay Survey Nail at Easting 840683.49, Northing 816709.55) should be provided and used to ensure the monitoring station is at the correct position before taking measurement and water samples.

Sampler

4.2.19 A water sampler is required. It should comprise a transparent PVC cylinder, with a capacity of not less than 2 litres, which can be effectively sealed with latex cups at both ends. The sampler should have a positive latching system to keep it open and prevent premature closure until released by a messenger when the sampler is at the selected water depth (for example, Kahlsico Water Sampler or an approved similar instrument).

Water Depth Detector

4.2.20 A portable, battery-operated echo sounder should be used for the determination of water depth at each designated monitoring station. This unit can either be hand held or affixed to the bottom of the work boat, if the same vessel is to be used throughout the monitoring programme.

Dissolved Oxygen and Temperature Measuring Instrument

4.2.21 The instrument should be a portable and weatherproof DO measuring instrument complete with cable and sensor, and use a DC power source. The equipment should be capable of measuring:

• a DO-level in the range of 0 - 20 mg/L and 0 - 200% saturation; and

• a temperature of 0 - 45 degree Celsius with a capability of measuring to ±0.1 degree Celsius.

4.2.22 It should have a membrane electrode with automatic temperature compensation complete with a cable. Sufficient stocks of spare electrodes and cables should be available for replacement where necessary. (For example, YSI model 59 meter, YSI 5739 probe, YSI 5795A submersible stirrer with reel and cable or an approved similar instrument).

4.2.23 Should salinity compensation not be built-in to the DO equipment, in-situ salinity should be measured to calibrate the DO equipment prior to each DO measurement.

Turbidity Measuring Instrument

4.2.24 Turbidity should be measured in-situ by the nephelometric method. The instrument should be portable and weatherproof using a DC power source complete with cable, sensor and comprehensive operation manuals. It should have a photoelectric sensor capable of measuring turbidity between 0 - 1000 NTU (for example, Hach model 2100P or an approved similar instrument). The cable should not be less than 25m in length. The meter should be calibrated in order to establish the relationship between NTU units and the levels of suspended solids. The turbidity measurement should be carried out on split water sample collected from the same depths of suspended solids samples.

Salinity Measuring Equipment

4.2.25 A portable salinometer capable of measuring salinity in the range of 0 - 40 parts per thousand (ppt) should be provided for measuring salinity of the water at each monitoring location.

pH Measuring Equipment

4.2.26 The instrument shall consist of a potentiometer, a glass electrode, a reference electrode and a temperature-compensating device. It shall be readable to 0.1 pH in a range of 0 to 14. Standard buffer solutions of at least pH 7 and pH 10 shall be used for calibration of the instrument before and after use. Details of the method shall comply with APHA, 19^th Edition 4500-HTB.

Sample Containers and Storage

4.2.27 Water samples for SS determination should be stored in suitable containers with no preservative added, packed in ice (cooled to 4℃ without being frozen) and delivered to the laboratory and analysed as soon as possible after collection. Sufficient volume of samples should be collected to achieve the detection limit.

Calibration of in-situ Instruments

4.2.28 All in-situ monitoring instruments should be checked, calibrated and certified by a laboratory accredited under HOKLAS or any other international accreditation scheme before use and subsequently re-calibrated at three monthly intervals throughout all stages of the water quality monitoring programme. Responses of sensors and electrodes should be checked with certified standard solutions before each use. Wet bulb calibration for a DO meter should be carried out before measurement at each monitoring location.

4.2.29 For the on-site calibration of field equipment, the BS 127:1993, Guide to Field and On-Site Test Methods for the Analysis of Water should be observed.

4.2.30 Sufficient stocks of spare parts should be maintained for replacements when necessary. Backup monitoring equipment should also be made available so that monitoring can proceed uninterrupted even when some equipment is under maintenance, calibration, etc.

Field Log

4.2.31 A sample data record sheet is shown in Appendix D for reference.

Laboratory Measurement / Analysis

4.2.32 Analysis of SS level should be carried out in a HOKLAS (or other international accredited laboratory that is HOKLAS-equivalent). Sufficient water samples of not less than 2 litres should be collected at the monitoring stations for carrying out the laboratory SS determination. All samples should be assigned a unique code and accompanied by Chain of Custody (COC) sheets.

4.2.33 The SS determination work should start within 24 hours after collection of the water samples. The SS analyses should follow the standard method APHA 2540D with a detection limit of 1 mg/L as described in APHA Standard Methods for the Examination of Water and Wastewater, 21^st Edition, unless otherwise specified.

4.2.34 Detailed testing methods, pre-treatment procedures, instrument use, Quality Assurance/Quality Control (QA/QC) details (such as blank, spike recovery, number of duplicate samples per batch, etc.), detection limits and accuracy should be submitted to EPD for approval prior to the commencement of monitoring programme. EPD may also request the laboratory to carry out analysis of known standards provided by EPD for quality assurance. The testing methods and related proposal should be checked and certified by IEC before submission to EPD for approval.

4.2.35 Additional duplicate samples may be required by EPD for inter laboratory calibration. Remaining samples after analysis should be kept by the laboratory for 3 months in case repeat analysis is required. If in-house or non-standard methods are proposed, details of the method verification may also be required to submit to EPD. In any circumstance, the sample testing should have comprehensive quality assurance and quality control programmes. The laboratory should prepare to demonstrate the programmes to EPD or his representatives when requested.

Event and Action Plan

4.2.36 The Action and Limit (AL) Levels for water quality are defined in Table 4.2. The actions in accordance with the Event and Action Plan in Table 4.3 should be carried out if the defined Action and/or Limit levels for water quality are exceeded at any designated monitoring points.

Table 4.2 Action and Limit Levels for Marine Water Quality

4.3 Mitigation Measures

4.3.1 Mitigation measures for construction phase water quality impacts have been recommended in the EIA Report. All the recommended mitigation measures are detailed in the implementation schedule in Appendix B. The Contractor should be responsible for the design and implementation of the mitigation measures.

4.4 Audit Requirements

4.4.1 Regular site inspection and audit at least once per week should be conducted during the construction phase of the Project to ensure the recommended mitigation measures are properly implemented.

5 Waste Management Implication

5.1 Introduction

5.1.1 Potential waste management implication arising from the construction and operational phases of the Project were addressed in the EIA Report. Waste management during the construction phase will mainly be the responsibility of the Contractor, who should implement the mitigation measures recommended in the EIA report in order to minimise waste or resolve the issues associated with the management of wastes. The Contractor should also ensure that all wastes produced during the construction phase are handled, stored and disposed of in accordance with good waste management practices, relevant legislation and waste management guidelines. Adverse environmental impacts would not be expected.

5.2 Mitigation Measures

5.2.1 With the proper handling, storage and disposal of wastes arising from the construction of the Project, it is anticipated that the potential adverse environmental impacts would be avoided or minimised.   During site inspections, the PM and ET should pay special attention to the issues relating to the waste management and check whether the Contractor has implemented the recommended good site practices and other mitigation measures as listed in Appendix B.  The Contractor should submit a Waste Management Plan (WMP) prior to the commencement of construction work, in accordance with PNAP No. 243 (ADV-19) so as to provide an overall framework of Waste Management and Reduction.

5.3 Audit Requirements

5.3.1 Regular audits and site inspection at least once per week should be carried out by the ET, AAHK / PM and Contractor to ensure that the recommended good site practices and other mitigation measure in Appendix B are properly implemented by the Contractor. The audits should look at all aspects of on-site waste management practices including the waste generation, storage, recycling, transportation and disposal. Apart from site inspections, documents including licenses, permits, disposal and recycling records should be reviewed and audited for the compliance with the legislation and contract requirements. The requirements of the environmental audit programme are set out in this EM&A Manual. The audit programme should verify the implementation status and evaluate the effectiveness of the mitigation measures.

5.3.2 During operational phase, only limited amount of wastes would be generated and no adverse waste impact would be anticipated with the implementation of the good waste management practices. No monitoring or audit is required during operational phase.

6 Marine Ecology

6.1 Introduction

6.1.1 Potential ecological impacts arising from the construction and operational phases of the Project were assessed in the EIA Report. Mitigation and precautionary measures have been recommended to further minimise potential direct and indirect impacts to ecological resources. With the implementation of appropriate marine ecological measures, no unacceptable marine ecological impact would be anticipated.

6.2 Mitigation Measures and Precautionary Measures

6.2.1 The recommended mitigation measures for alleviating marine ecological impacts arising from construction works include vessel speed limit control on all construction-related vessels and the implementation of good site practices and water quality measures to minimise disturbance to marine fauna near works area, as listed in Appendix B. Indirect disturbance to marine habitats and fauna during operation phase will be minimal under the establishment of a proper surface water drainage system to collect road runoff.

6.2.2 Coral translocation is recommended as a precautionary measure to further reduce the direct impact on the 23 coral colonies recorded at REA2 near the bridge foundation works.

6.3 Monitoring and Audit Requirements

6.3.1 There will be a water quality monitoring programme during the construction phase of the project to ensure that all the recommended water quality measures and best management practices are properly implemented. Details are discussed in Section 4 of this Manual.

6.3.2 All marine species of conservation importance (e.g. hard coral Oulastrea crispata) should be protected as far as practicable. Twenty three gorgonian coral colonies (Guaiagorgia sp.) recorded in Rapid Ecological Assessment (REA) transect REA 2 should be translocated to nearby suitable habitat(s) as a precautionary measure. A detailed Coral Translocation Proposal, including description of methodology (e.g. pre-translocation survey, identification/ proposal of coral recipient site(s)) and post-translocation monitoring programme, should be prepared and subject to agreement with the authority before commencement of the coral translocation. All the precautionary pre-translocation survey, translocation exercises and precautionary post-translocation monitoring should be conducted by experienced marine ecologist(s) with at least 5 years relevant experience.

6.3.3 A speed limit of 10 knots should be strictly enforced on all construction-related vessels based upon a precautionary approach to avoid vessel collision to Chinese White Dolphins.

6.3.4 Precautionary post-translocation coral monitoring surveys would be conducted on translocated corals. The results of the post-translocation monitoring should be reviewed with reference to findings of the pre-translocation survey and the data from original colonies at the recipient site.

7 Landscape and Visual Impact

7.1 Introduction

7.1.1 Potential landscape and visual impacts arising from the construction and operational phases of the Project were assessed and landscape and visual mitigation measures were recommended in the EIA Report.

7.3 Mitigation Measures

7.3.1 The landscape and visual mitigation measures should be incorporated in the detailed design. The mitigation measures during construction and operation phases as recommended in the EIA Report are presented in Appendix B. Where feasible, the construction phase mitigation measures should be implemented as early as possible in order to minimise the landscape impacts in the construction stage while the mitigation measures for the operation phase should be adopted during the detailed design and be built as part of the construction works so that they are in place before commissioning of the Project.

7.3.2 Any potential conflicts among the proposed mitigation measures, the Project works and operational requirement should also be identified and resolved as early as practicable. Any changes to the mitigation measures should be incorporated in the detailed design.

7.4 Audit Requirements

7.4.1 Site audits should be undertaken during the construction phase of the Project to check that the proposed landscape and visual mitigation measures are properly implemented and maintained as per their intended objectives. Site inspections should be undertaken by the ET at least once every month during the construction period.

8 Impact on Cultural Heritage

8.1 Introduction

8.1.1 Given no cultural heritage resource is identified within the works area, no impact is anticipated to cultural heritage resource during construction and operational phases of the Project. Therefore, no monitoring and audit programme on cultural heritage would be required.
