4.1.1.1           The EIA has considered the potential air quality impacts during construction phase of the Project. Based on the assessment results, adverse construction dust impact is not anticipated with the implementation of mitigation measures. Construction dust monitoring and regular site environmental audit are recommended to check the implementation of mitigation measures and good site practices. The EIA has also concluded that there will be no adverse air quality impacts during operational phase and hence, mitigation measures, environmental monitoring and site inspections during operational phase are not required.

4.2                     Mitigation Measures

4.2.1.1           In order to reduce the construction dust emission from the Project, regular watering and other good site practices should be implemented. In addition, mitigation measures to control the exhaust emissions from construction plant and equipment are also required. All the recommended good practices are summarised in the Environmental Mitigation Implementation Schedule (EMIS) in Appendix 4.1.

4.3                     Air Quality Monitoring Parameters

4.3.1.1           Monitoring and audit of the Total Suspended Particulate (TSP) levels shall be carried out by the ET to ensure that any deteriorating air quality could be readily detected and timely actions could be taken to rectify the situation.

4.3.1.2           One-hour TSP levels shall be measured to indicate the impacts of construction dust on air quality. The 1-hour TSP levels shall be measured by following the standard high volume sampling method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B. Upon approval of the IEC and EPD, 1-hour TSP levels can be measured by direct reading method with using handheld dust particle measuring device which are capable of producing comparable results as that by the high volume sampling method, to indicate short event impacts.

4.3.1.3           All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, and any other local atmospheric factors affecting or affected by site conditions, etc., shall be recorded down in detail. A sample data sheet is shown in Appendix 4.2.

Note:

[1] The monitoring period is subject to the construction programme of the relevant contracts in the construction phase.

[2] Monitoring location DM-1a shall supersede DM-1 once the planned development at DM-1a commences operation during the corresponding construction activity.   

4.6.1.2           When alternative monitoring locations are proposed, the proposed locations should, as far as practicable:

·            Monitoring at site boundary or at ASRs close to the major site activities which are likely to have air quality impacts;

·            Monitoring as close as possible to the ASRs as defined in the EIAO-TM;

·            Assurance of the minimal disturbance to the occupants and working under a safe condition during monitoring; and

·            take into account the prevailing meteorological conditions.

4.6.1.3           The ET shall agree with IEC on the position of the HVS for the installation of the monitoring equipment. When positioning the samplers, the following points shall be noted:

·            a horizontal platform with appropriate support to secure the samplers against gusty wind should be provided;

·            no two samplers should be placed less than 2 meters apart;

·            the distance between the sampler and an obstacle, such as buildings, should be at least twice the height that the obstacle protrudes above the sampler;

·            a minimum of 2 meters of separation from walls, parapets and penthouses is required for rooftop samplers;

·            a minimum of 2 meters separation from any supporting structure, measured horizontally is required;

·            no furnace or incinerator flue is nearby;

·            airflow around the sampler is unrestricted;

·            the sampler is more than 20 meters from the dripline;

·            any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring;

·            permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

·            a secured supply of electricity is needed to operate the samplers.

4.6.1.4           The ET may, depending on site conditions and monitoring results, decide whether additional monitoring locations shall be included or any monitoring locations could be removed / relocated during any stage of the construction phase, upon the agreement from the IEC and EPD.

4.7                     Baseline Monitoring

4.7.1.1           Baseline monitoring shall be carried out at all of the designated monitoring locations (see Table 4.1) for at least two weeks prior to the commissioning of major construction works to obtain ambient 1-hour TSP samples. Ambient 1-hour sampling should also be done at least 3 times per day at each monitoring station.

4.7.1.2           During the baseline monitoring, the monitoring locations should consider locations without any major construction or dust generation activities in the vicinity as far as practicable. As some of the monitoring locations listed in Table 4.1 is planned development and may be located within construction sites during the baseline monitoring period, the baseline monitoring at the planned development shall refer to the nearby baseline monitoring location at the existing development. Before commencing baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

4.7.1.3           In case the baseline monitoring cannot be carried out at the designated monitoring locations, the ET shall carry out the monitoring at alternative locations that can effectively represent the baseline conditions at the impact monitoring location. The alternative baseline monitoring locations shall be agreed with the IEC and EPD prior to commencement of baseline monitoring.

4.7.1.4           In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference.

4.7.1.5           General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources should also be recorded throughout the baseline monitoring period. If the ET Leader considers that significant changes in the ambient conditions have arisen, a repeat of the baseline monitoring may be carried out to update the baseline levels and air quality criteria, after consultation and agreement with the ER, IEC and EPD.

4.8                     Impact Monitoring

4.8.1.1           The ET shall carry out impact monitoring during major construction activities for the Project as specified in Table 4.1. For 1-hour TSP monitoring, the sampling frequency of at least 3 times in every 6 days should be undertaken when the highest dust impact occurs.

4.8.1.2           The monthly schedule of the impact monitoring programme should be drawn up by the ET one month prior to the commencement of the scheduled construction period. Before commencing impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit.

4.9                     Action and Limit Levels

4.9.1.1           The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring during the construction phase. The ET shall compare the impact monitoring results with air quality criteria set up for 1-hour TSP. Table 4.2 shows the air quality criteria, namely Action and Limit Levels to be used.

5                           Noise Impact

5.1                     Introduction

5.1.1.1           The EIA Report has considered the potential noise impacts associated with the construction and operation of the Project. Airborne construction noise arising from the construction activities, would be the major potential noise impacts during the construction phase. With the implementation of mitigation measures, adverse airborne construction noise is not anticipated. Airborne construction noise monitoring, regular site environmental inspection during the construction phase is required. During the operational phase, adverse airborne noise impact from rail and fixed noise sources is not anticipated with the implementation of mitigation measures. Thus, airborne rail noise commissioning test and monitoring as well as fixed plant noise audit for planned fixed noise sources shall be conducted prior to the operation of the Project to confirm that the relevant standards stipulated in EIAO-TM and Noise Control Ordinance (NCO) would be complied with. As exceedance of noise criteria from groundborne construction noise and groundborne rail noise under unmitigated scenario of the Project is not anticipated, mitigation measure is not required. Nonetheless, groundborne rail noise commissioning test is recommended.

5.2                     Mitigation Measures

5.2.1                Construction Phase

5.2.1.1           Adverse airborne construction noise impact is not anticipated with the implementation of mitigation measures such as good site practices, use of quality powered mechanical equipment (QPME) and use of temporary noise barriers and noise enclosures to screen noise from relatively static PMEs etc. All the recommended mitigation measures and good site practices are summarised in the EMIS given in Appendix 4.1.

5.2.1.2           Adverse groundborne construction noise impact is not anticipated in the unmitigated scenario. Hence, no mitigation measure is recommended.

5.2.2                Operational Phase

5.2.2.1           With the implementation of mitigation measures such as speed reduction and noise barrier, adverse rail noise impact is not anticipated. For the proposed fixed noise sources, no adverse impact is expected with the properly selection of the equipment and installation of acoustic attenuators such as enclosure and silencer. All of the noise mitigation measures during operational phase are summarised in the EMIS given in Appendix 4.1.

5.2.2.2           Adverse groundborne rail noise impact is not anticipated in the unmitigated scenario. Hence, no mitigation measure is recommended.

5.3                     Noise Monitoring Parameters

5.3.1                Construction Phase

5.3.1.1           Airborne construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30min) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays.  For all other time periods, Leq (5min) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. A sample data sheet is shown in Appendix 5.1.

5.3.1.2           As supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.

5.3.2                Operational Phase

5.3.2.1           As adverse groundborne rail noise and fixed noise sources impacts during the operational phase is not anticipated, noise monitoring of groundborne rail noise and fixed plant noise is not required. Nevertheless, fixed plant noise, groundborne and airborne rail noise commissioning test should be conducted prior to the operation of the Project and noise monitoring for the airborne rail noise is recommended to verify the prediction.

5.4                     Monitoring Equipment for Construction and Operational Phases

5.4.1.1           As referred to the Technical Memorandum (TM) issued under the NCO, sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement, the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agrees to within 1.0 dB.

5.4.1.2           Noise measurements should be made in accordance with standard acoustical principles and practices in relation to weather conditions.

5.4.1.3           The ET is responsible for the provision, installation, operation, maintenance, dismantle of the monitoring equipment. He shall ensure that sufficient noise measurement equipment and associated instrumentation are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

5.5                     Construction Noise Monitoring

5.5.1                Monitoring Locations and Methodology

Note:

[1] The monitoring period is subject to the construction programme of the relevant contracts in the construction phase.

 

5.5.1.2           When alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria:

·       At locations close to the major site activities which are likely to have noise impacts;

·       Close to the most affected existing noise sensitive receivers; and

·       For monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance to the occupants during monitoring.

5.5.1.3           The monitoring station shall normally be at a point 1m from the exterior of the sensitive receiver building facade and be at a position 1.2m above the ground. If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made. For reference, a correction of +3 dB(A) shall be made to the free field measurements.  The ET shall agree with the IEC on the monitoring position and the corrections adopted. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions.

5.5.1.4           The status and locations of the NSRs may change after issuing this EM&A Manual. In such case, the ET shall propose updated monitoring locations and seek approval from the ER and agreement from the IEC and EPD on the proposal.

5.5.2                Baseline Monitoring

5.5.2.1           The ET shall carry out baseline noise monitoring in all identified monitoring stations prior to the commencement of the construction works. There shall not be any construction activities in the vicinity of the stations during the baseline monitoring. As some of the monitoring locations listed in Table 5.1 is planned development and may be located within construction sites during the baseline monitoring period, the baseline monitoring at the planned development shall refer to the nearby baseline monitoring location at the existing development. Continuous baseline noise monitoring for the A-weighted levels Leq, L10 and L90 shall be carried out daily for a period of at least two weeks in a sample period of 30 minutes between 0700 and 1900, and 5 minutes between 1900 and 0700 as well as all time at general holidays including Sundays. A schedule on the baseline monitoring shall be submitted to the ER and IEC for approval before the monitoring starts.

5.5.2.2           In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference.

5.5.3                Impact Monitoring

5.5.3.1           During normal construction working hours (0700-1900 Monday to Saturday), monitoring of Leq, (30min) noise levels shall be carried out at the agreed monitoring locations once every week in accordance with the methodology in the TM issued under NCO.

5.5.3.2           In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Event and Action Plan, shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.

5.5.3.3           The monthly schedule of the impact monitoring programme should be drawn up by the ET at least 2 weeks prior to the commencement of the scheduled construction period. Before commencing impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit.

5.5.4                Action and Limit Levels

Airborne Construction Noise

5.5.4.1           The ET shall compare the airborne construction noise monitoring results with noise criteria. Table 5.3 shows the noise criteria, namely Action and Limit Levels to be used.

Table 5.3    Action and Limit Levels for airborne construction noise

Time Period

Action Level

Limit Level

0700 - 1900 hours on normal weekdays

Notes:

If works are to be carried out during restricted hours, the conditions stipulated in the construction noise permit issued by the Noise Control Authority have to be followed.

*Reduce to 70 dB(A) for schools and 65 dB(A) during school examination periods.

5.5.4.2           To account for cases in which ambient noise levels, as identified by baseline monitoring, approach or exceed the stipulated Limit Levels prior to the commencement of construction, a Maximum Acceptable Impact Level, which incorporates the baseline noise levels and the identified construction noise Limit Level, may be defined and agreed with the EPD. The amended level will be greater than 75 dB(A) and will represent the maximum acceptable noise level at a specific monitoring station. Correction factors for the effects of acoustic screening and/or architectural features of NSRs may also be applied as specified in the Technical Memorandum on Noise from Construction Work other than Percussive Piling (GW-TM).

5.5.5                Event and Action Plan

5.5.5.1           Should non-compliance of the noise criteria occur, actions in accordance with the Event and Action Plan in Table 5.5 shall be carried out.

5.6                     Rail Noise Commissioning Test and Operational Monitoring

Airborne Rail Noise

5.6.1.1           Before the Project is in operation, a commissioning test will be conducted by the ET for verification of EIA predictions and checking compliance of the airborne noise levels within the NCO noise criteria. Measurement of train noise levels will be carried out in the commissioning test at the proposed monitoring locations during night-time period, i.e. 2300-0700 before the Project is in operation. Background noise levels shall also be measured.

5.6.1.2           Monitoring of Leq (30mins) train noise levels will be carried out at the proposed monitoring locations during night-time period, i.e. 2300-0700 on a monthly basis after the Project is in operation (i.e. after the commencement of the operation of the TCE Station). Background noise levels shall also be measured. It is recommended to conduct the monitoring for the initial start-up for 3 months to verify the prediction. With compliance of the noise limit and agreement from IEC, the 3-month monitoring will be terminated.

Groundborne Rail Noise

5.6.1.3           Before the Project is in operation, a commissioning test will be conducted for checking the compliance of the groundborne noise levels within the NCO noise criteria.  Measurement of train noise levels will be carried out in the commissioning test at the proposed monitoring locations during night-time period, i.e. 2300-0700 before the Project is in operation (i.e. before the commencement of the operation of TCW Station). Background noise levels shall also be measured.

5.6.2                Monitoring Equipment and Methodology

5.6.2.1           The monitoring equipment and methodology for rail noise commissioning test and operational monitoring should be the same as those recommended for construction noise monitoring.

5.6.3                Monitoring Locations

5.6.4                Background Noise Monitoring

5.6.4.1           Existing Leq (30mins) levels should be monitored at the monitoring locations without trains running to obtain the ambient noise levels. After the train noise levels are measured (if measured directly), these ambient levels should be deducted from the measured Leq (30mins) levels to obtain the operational noise levels in the absence of ambient noise.

5.7                     Fixed Plant Noise Audit

5.7.1.1           The maximum allowable sound power levels of the identified fixed noise sources have been established in the EIA Report. The Contractor should implement and refine the specified sound power levels as appropriate to ensure compliances with the noise standards stipulated in the EIAO-TM and NCO for the fixed plant operations.

5.7.1.2           The Contractor should also carry out a noise audit for all fixed noise sources before the operation of the Project, in order to ensure compliance of the noise levels with the stipulated noise standards in the EIAO-TM and NCO.

 

6                           Water Quality Impact

6.1                     Introduction

6.1.1.1           The EIA Report has assessed the potential water quality impacts associated with the construction and operation of the Project. According to the EIA Report, adverse environmental impact is not anticipated during the construction and operational phases with proper implementation of the recommended mitigation measures and good site practices.

6.2                     Mitigation Measures

6.2.1                Construction Phase

6.2.1.1           During the construction phase, recommended mitigation measures such as good site practices to control construction site runoff, providing perimeter drains, on-site treatment of tunnelling wastewater prior to discharge, etc., should be implemented. In addition, enhancement measures including provision of barrier such as sheet piles or hoarding with concrete footing along the western boundary of the construction site/works areas for TCW Station should be also implemented. All the recommended mitigation measures are summarised in the EMIS in Appendix 4.1.

6.2.2                Operational Phase

6.2.2.1           With proper connection to the public drainage and sewage systems and mitigation measure in place such as stormwater surface runoff discharged to the nearby government drainage system with provision of silt trap, standard oil interceptors and the practices outlined in ProPECC PN 5/93, application of a discharge licence for the discharge of commercial and industrial effluent, adverse impact is not anticipated during the operational phase.

6.3                     Environmental Monitoring and Site Audit Requirements

6.3.1                Construction Phase

6.3.1.1           Apart from the water quality measurement specified in the discharge licence under the WPCO, no additional water quality monitoring is considered necessary. The necessary water quality measurements under the WPCO shall be conducted at the discharge location(s) specified in the licence conditions.

6.3.1.2           Weekly environmental site inspection shall be carried out by the ET during the construction phase to ensure that the recommended good site practices and other mitigation measures are implemented by the Contractor. Apart from the environmental site inspections, documents including discharge licenses shall be reviewed and audited for the compliance with the legislation and contract requirements.

6.3.2                Operational Phase

6.3.2.1           No water quality monitoring and site audit are required. Nevertheless, the conditions specified in the discharge licence for the discharge of commercial and industrial effluent shall be followed.


7                           Waste Management Implications

7.1                     Introduction

7.1.1.1           The quantity and timing for the generation of waste during construction phase have been estimated in the EIA Report. Measures including the opportunity for on-site sorting, reusing Construction and Demolition (C&D) materials etc., are devised in the construction methodology to minimise the surplus materials to be disposed. Chemical waste should be collected by licensed chemical waste collectors for proper disposal.

7.1.1.2           During the operational phase, the major types of waste to be generated are municipal solid waste from the public, station employees and commercial operators within the stations and chemical waste from the maintenance of the stations, tracks and EAP/EEP.

7.2                     Mitigation Measures

7.2.1                Construction Phase

7.2.1.1           All the proposed mitigation measures during construction phase are stipulated in the EIA Report and summarised in Appendix 4.1.

7.2.1.2           Waste will be handled in accordance with the relevant legislation and guidelines and with the implementation of the proposed mitigation measures, no adverse environmental impacts from waste management are anticipated. EM&A is required for waste management during the construction phase only and the effective management of waste arising during the construction phase will be monitored through the site audit programme. The aims of the waste audit are:

·       To ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmental acceptable manner; and

·       To encourage the reuse and recycling of material.

7.2.1.3           A trip-ticket system should be operated to monitor all movements of both inert and non-inert C&D materials for disposal at landfill and chemical wastes which will be collected by licensed chemical waste collectors to licensed facilities for final treatment and disposal. Land-based sediment will be handled, stored and disposed of in accordance with good waste management practices, relevant legislation and waste management guidelines. All dump trucks engaged on site for delivery of inert C&D materials from the site to Pubic Fill Reception Facilities (PFRFs) should be equipped with GPS or equivalent system for tracking and monitoring of their travel routings and parking locations to prohibit illegal dumping and landfilling of C&D materials. Record and analysis of data collected by the mentioned GPS or equivalent system should be kept. Recommendations have been made in the EIA Report to ensure proper treatment and proper disposal of these wastes and summarised in Appendix 4.1.

7.2.2                Operational Phase

7.2.2.1           For the municipal solid waste generated from the public, station employees and commercial operators within the stations, it should be separated from chemical waste by providing separated bins for storage to maximize the recyclable volume as far as practicable. A reputable waste collector should be employed to remove municipal solid waste regularly to minimize odour, pest and litter impacts. Other than municipal solid waste, opportunities for the use and recycling of chemical wastes where possible.  As chemical waste is expected to be generated, a trip-ticket system should be operated in accordance with the Waste Disposal (Chemical Waste) (General) Regulation to monitor all movements of chemical wastes which will be collected by a licensed collector to a licensed facility for final treatment and disposal. With proper management, adverse waste management implications are not anticipated.

7.3                     Environmental Monitoring and Site Audit Requirements

7.3.1                Construction Phase

7.3.1.1           The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant licenses/ permits for waste disposal. The ET shall ensure that the Contractor has obtained from the appropriate authorities the necessary waste disposal permits or licenses including:

·            Chemical Waste Disposal License under the Waste Disposal Ordinance (Cap 354);

·            Dumping at Sea Ordinance (DASO) (Cap. 466) if marine disposal of land-based sediment is unavoidable; 

·            Dumping License under the Land (Miscellaneous Provisions) Ordinance (Cap 28); and

·            Water Pollution Control Ordinance License under the Water Pollution Control Ordinance

7.3.1.2           The Contractor shall refer to EPD’s Guidance Notes for License Application when applying for the license/ permit and the ET shall refer to these Guidance Notes for auditing purposes.

7.3.1.3           Regular audits and site inspections should be carried out during the construction phase by the ET to ensure that the recommended good site practices and other mitigation measures recommended in the EIA Report and in Appendix 4.1 are properly implemented by the Contractor. The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, a Waste Management Plan (WMP) as part of the Environmental Management Plan (EMP) shall be prepared. Documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.

7.3.1.4           The requirements of the environmental audit programme are set out in Section 14 of this Manual. The audit programme will verify the implementation status and evaluate the effectiveness of the mitigation measures.

7.3.2                Operational Phase

7.3.2.1           As it is anticipated that there would not be any insurmountable impacts during the operational phase, monitoring and audit requirements are not required.


8                           Land Contamination Impact

8.1                     Introduction

8.1.1.1           As outlined in Section 7 of the EIA Report, based on the desktop review findings of selected aerial photos, the information collected during site surveys, as well as from EPD and Fire Services Department (FSD), there are no signs of land contamination in the Project Site. In addition, potentially contaminating activities or land use under the Project are not anticipated.

8.2                     Mitigation Measures

8.2.1.1           Potential land contamination issue within the Project Site were not identified and hence mitigation measures are not required for both construction and operational phases. Nevertheless, since major construction works for the Project are anticipated to commence in 2023, site re-appraisal would be recommended by the Project Proponent to assess the latest site situation prior to the commencement of the construction.  The objective of re-appraisal is to ensure any new changes in land use activities that might cause land contamination issue after the agreement of the Land Contamination Review but before commencement of the construction could be addressed.

8.3                     Environmental Monitoring and Site Audit Requirements

8.3.1.1           Environmental monitoring and site audit are not required for both construction and operational phases.


9                           Ecology

9.1                     Introduction

9.1.1.1           The EIA Report has evaluated the ecological impacts associated with the construction and operation of the Project and recommended ecological mitigation measures to avoid, minimise and compensate the impact arising from the Project.

1.1.1.1           The required mitigation measures adopted to avoid, minimise and mitigate for the ecological impacts arising from the Project were identified in Section 8 of the EIA Report and are described in the following sections. The proposed ecological mitigation measures should be checked as an element of the environmental audit programme under the Project.

9.2                     Mitigation Measures

9.2.1                Construction Phase

9.2.1.1           The proposed mitigation measures for ecological impacts are summarised in the EMIS in Appendix 4.1.

9.2.1.2           The following key considerations throughout the entire project development and design have been duly considered to avoid/ minimise the impacts.

·       Avoidance of marine works;

·       Avoidance of Tung Chung River and its estuary, and Tai Ho Wan;

·       Avoidance of works within the intertidal zone;

·       Avoidance of country parks, SSSI, CA and CPA;

·       Avoidance of mature woodland;

·       Avoidance of re-diversion of Wong Lung Hang nullah;

·       Avoidance of Flora of Conservation Importance by protection zone;

·       Minimisation of surface runoff and provision of necessary treatment facilities;

·       Minimisation of noise disturbance during construction;

·       Minimisation of air quality impact during construction; and

·       Minimisation of human disturbance during construction.

9.2.2                Operational Phase

9.2.2.1           Since both direct and indirect ecological impacts are considered insignificant, no mitigation measures are required.

9.3                     Environmental Monitoring and Site Audit Requirements

9.3.1                Construction Phase

9.3.1.1           Site inspections once per week should be undertaken to inspect the construction activities and works areas to ensure the recommended mitigation measures are properly implemented.

9.3.2                Operational Phase

9.3.2.1           Since both direct and indirect ecological impacts are considered insignificant, no environmental monitoring and site audit are required during operational phase.


10                      Fisheries

10.1                Introduction

10.1.1.1       The EIA Report concluded that there is no direct impact to fisheries resources as no marine works nor marine dredging would be required in the Project and the TCL realignment works at TCE is land-based. Potential fisheries resources would be affected by indirect water quality impact which would be controlled by construction site best practices. Hence, adverse fisheries impacts are not anticipated in both construction and operational phases.

10.2                Mitigation Measures

10.2.1.1       No specific fisheries mitigation measures and monitoring would be required during both construction and operational phases. Mitigation measures recommended in the water quality impact assessment will also minimise any adverse impacts on fisheries.

10.3                Environmental Monitoring and Site Audit Requirement

1.1.1.2           No specific fisheries monitoring and audit is required for both construction and operational phases.

 

11                      Landscape and Visual

11.1                Introduction

1.1.1.1           The EIA has recommended that EM&A for landscape and visual resources is undertaken during the design, construction and operational phases of the project. The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that any potential conflicts between the proposed landscape measures and any other works of the Project would be resolved at early as practical without affecting the implementation of the mitigation measures.

11.2                Mitigation Measures

11.2.1.1       The landscape and visual impact assessment of the EIA Report proposes a number of mitigation measures to ameliorate the landscape and visual impacts of the Project. These measures are listed in Table 11.1 below and the implementation is summarised in the EMIS in Appendix 4.1.

12                      Cultural Heritage

12.1                Introduction

12.1.1.1       The graded, non-graded built heritage and declared monuments identified within the assessment area will not be affected by the Project. In addition, the sites of archaeological interest and an archaeological potential area are identified within or near the Project. No major archaeological impacts are expected within the whole project area during the construction and operational phases. At the extreme northern end of the TCW Station area and above and adjacent to the tunnel alignment is an area of unexplored archaeological interest, further archaeological survey including field scan, six auger tests and two test pit excavations are recommended to be conducted by a qualified archaeologist who obtains a licence under the Antiquities and Monuments Ordinance (Cap. 53) to verify presence of any archaeological remains.  Locations and scope should be agreed with AMO prior to implementation.  The exact locations of the auger tests and test pits would be subject to site circumstances and constraints. Subject to the findings of the further archaeological testing, options for mitigation measures such as in-situ preservation, relocation and preservation by record etc would be fully investigated and agreed with AMO.

12.1.1.2       AMO should be informed immediately in case of discovery of antiquities or supposed antiquities in the course of the project works in accordance with the Antiquities and Monuments Ordinance (Cap. 53), so that appropriate mitigation measures, if needed, can be timely formulated and implemented in agreement with AMO.

12.2                Mitigation Measures

12.2.1             Archaeology

Construction Phase

12.2.1.1       The area at the northern end of the TCW Station will be subject to further archaeological survey after land resumption. The area can be referred to Figure 11.7 of the EIA Report. Subject to the findings of archaeological work, appropriate mitigation measures would be proposed by the project proponent in prior agreement with Antiquities and Monuments Office before the construction phase of the proposed development. The implementation of the above mitigation measure is summarised in the EMIS in Appendix 4.1.

Operational Phase

12.2.1.2       The vibration level of the train during operation within Ma Wan Chung Site of Archaeological Interest (SAI) and area of archaeological interest will be an acceptable impact on the structural remains of the SAI. No mitigation measures will be required.

12.2.2             Built Heritage

12.2.2.1       As no direct impact to built heritage is anticipated, mitigation measures are not required for both construction and operational phases.

12.3                Environmental Monitoring and Site Audit Requirements

12.3.1             Archaeology

12.3.1.1       As no archaeological impact is expected during both construction and operational phases of the Project, monitoring and audit are considered not necessary.

12.3.2             Cultural Heritage

12.3.2.1       As the Project would not generate or induce any additional cultural heritage impact during both construction and operational phases of the Project, monitoring and audit are considered not necessary.


 

13                      Hazard to Life

13.1                Introduction

13.1.1.1       The EIA Report concluded that with the implementation of proposed mitigation measures, no insurmountable potential risk arising from the transport and use of explosives is anticipated. In addition, The Project does not fall into consultation zone of any Potentially Hazardous Installations (PHIs). Therefore, potential risk relating PHI is not anticipated. The operation of the Project does not involve any use of explosives, potential risk during operational phase is not envisaged. 

13.2                Mitigation Measures

13.2.1             Construction Phase

13.2.1.1       No potential risk would be anticipated with the implementation of good site practices and design measures for the potential use of explosives. Hence, mitigation measures are not required.

13.2.2             Operational Phase

13.2.2.1       No specific mitigation measures are required as no potential risk during operational phase is envisaged.

13.3                Environmental Monitoring and Site Audit

13.3.1             Construction Phase

13.3.1.1       No potential risk would be anticipated with the implementation of good site practices and design measures for the potential use of explosives. Hence, environmental monitoring and site audit are not required.

13.3.2             Operational Phase

13.3.2.1       No specific mitigation measures are required as no potential risk during operational phase is envisaged. Hence, environmental monitoring and site audit are not required.


14                      Site Environmental Audit

14.1                Site Inspection

14.1.1.1       Site inspection provides a direct means to initiate and enforce specified environmental protection and pollution control measures. These shall be undertaken routinely to inspect construction activities in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented. Site inspection is one of the most effective tools to enforce the environmental protection requirements at the works area.

14.1.1.2       The ET shall be responsible for formulating the environmental site inspection programme as well as the deficiency and action reporting system, and for carrying out the site inspections. The proposal for rectification, if any, should be prepared and submitted to the ET Leader and IEC by the Contractor.

14.1.1.3       Regular site inspections shall be carried out and led by the ER and attended by the Contractor and ET at least once per week during the construction phase. The IEC shall undertake regular site audit at least once per month to assess the performance of the Contractor(s). The areas of inspection shall not be limited to the environmental situation, pollution control and mitigation measures within the site. It should also review the environmental conditions of locations outside the works area which is likely to be affected, directly or indirectly, by the construction site activities of the Project. The ET shall make reference to the following information in conducting the inspection. During the inspection, the following information should be referred to:

(i)              EIA Report and EM&A Manual recommendations on environmental protection and pollution control mitigation measures;

(ii)            ongoing results of the EM&A programme;

(iii)          works progress and programme;

(iv)           individual works methodology proposals (which shall include the proposal on associated pollution control measures);

(v)             contract specifications on environmental protection;

(vi)           relevant environmental protection and pollution control legislations; and

(vii)         previous site inspection results undertaken by the ET and others.

14.1.1.4       The Contractor shall keep the ER and ET Leader updated with all the relevant environmental related information on the construction contract necessary for him to carry out the site inspections. Site inspection results and associated recommendations for improvements to the environmental protection and pollution control efforts should be recorded and followed up by the Contractor in an agreed time-frame. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, and the deficiency and action reporting system formulated by the ET, to report on any remedial measures subsequent to the site inspections.

14.1.1.5       The ER, ET and the Contractor should also carry out ad-hoc site inspections if significant environmental problems are identified. Inspections may also be required subsequent to receipt of a valid environmental complaint, or as part of the investigation work, as specified in the Event and Action Plans for the EM&A programme.

14.2                Environmental Compliance

14.2.1.1       There are statutory requirements on environmental protection and pollution control requirements with which construction activities must comply.

14.2.1.2       In order to ensure the works comply with statutory requirements, all method statements of works should be submitted by the Contractor to the ER for approval and to the ET Leader to ensure sufficient environmental protection and pollution control measures have been included. EMIS is summarised in Appendix 4.1. Any proposed changes to the mitigation measures shall be certified by the ET Leader and verified by the IEC as conforming to the relevant information and recommendations contained in the EIA Report.

14.2.1.3       The ER and ET shall also review the progress and programme of the works to check that relevant environmental legislation has not been violated, and that any foreseeable potential for violating laws can be prevented.

14.2.1.4       The Contractor should provide the update of the relevant documents to the ET Leader so that checking can be carried out. The document shall at least include the updated Works Progress Reports, updated Works Programme, method statements, any application letters for different licenses / permits under the environmental protection laws, and copies of all valid licenses / permits. The site diary and environmental records shall also be available for inspection by the relevant parties.

14.2.1.5       After reviewing the document, the ET shall advise the IEC and the Contractor of any non-compliance with legislative requirements on environmental protection and pollution control so that they can timely take follow-up actions as appropriate. If the follow-up actions still result in potential violation of environmental protection and pollution control requirements, the ER and ET should provide further advice to the Contractor to take remedial action to resolve the problem.

14.2.1.6       Upon receipt of the advice, the Contractor shall undertake immediate actions to correct the situation. The ER and ET shall follow up to ensure that appropriate action has been taken in order to satisfy legal requirements.

14.3                Choice of Construction Method

14.3.1.1       At times during the construction phase, the Contractor may submit method statements for various aspects of construction. This state of affairs would only apply to those construction methods that the EIA has not imposed conditions while for construction methods that have been assessed in the EIA, the Contractor is bound to follow the requirements and recommendations in the EIA study. The Contractor’s options for alternative construction methods may introduce adverse environmental impacts into the Project. It is the responsibility of the Contractor and ET, in accordance with established standards, guidelines and EIA study recommendations and requirements, to review and determine the adequacy of the environmental protection and pollution control measures in the Contractor’s proposal in order to ensure no unacceptable impacts would result. To achieve this end, the ET shall provide a copy of the Proactive Environmental Protection Proforma as shown in Appendix 14.1 to the IEC for approval before commencement of work. The IEC should audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts.

14.4                Environment Complaints

14.4.1.1       The following procedures should be undertaken upon receipt of any environmental complaint:

·     The Contractor to log complaint and date of receipt onto the complaint database and inform the ER, ET and IEC immediately;

·     The Contractor to investigate, with the ER and ET, the complaint to determine its validity, and assess whether the source of the problem is due to construction works of the Project with the support of additional monitoring frequency and stations, if necessary;

·     The Contractor to identify remedial measures in consultation with the IEC, ET and ER if a complaint is valid and due to the construction works of the Project;

·     The Contractor to implement the remedial measures as required by the ER and to agree with the ET and IEC any additional monitoring frequency and stations, where necessary, for checking the effectiveness of the remedial measures;

·     The ER, ET and IEC to review the effectiveness of the Contractor's remedial measures and the updated situation;

·     The ET/Contractor to undertake monitoring and audit to verify the situation if necessary, and oversee that circumstances leading to the complaint do not recur;

·     If the complaint is referred by the EPD, the Contractor to prepare interim report on the status of the complaint investigation and follow-up actions stipulated above, including the details of the remedial measures and monitoring identified or already taken, for submission to EPD within the time frame assigned by the EPD; and

·      The ET to record the details of the complaint, results of the investigation, subsequent actions taken to address the complaint and updated situation including the effectiveness of the remedial measures, supported by regular and additional monitoring results in the monthly EM&A reports.
