1                                Introduction

1.1                          Background

1.1.1.1           The 30-hectare Siu Ho Wan Depot (SHD) has been highlighted in both 2015 and 2016 Policy Address as a potential railway site being explored by MTR Corporation Limited (MTRCL) (the Project Proponent) in collaboration with the Government to provide housing supply.

1.1.1.2           In the 2017 Policy Address, the Chief Executive announced the initiative to commence the statutory planning procedures for SHD this year, with the aim to provide not less than 14,000 residential units in the medium to long term.

1.1.1.3           The Lantau Development Advisory Committee (LanDAC) has also recommended “Strategic Economic and Housing Development” as the planning theme for the North Lantau Corridor.  The proposed comprehensive development atop SHD is in line with the planning theme, which has been earmarked as one of the medium-term projects in the First-term Work Report published by LanDAC in January 2016.

1.1.1.4           The Project Proponent supports Government’s policy initiative to make better use of railway land to provide housing supply by commissioning a consultancy study to optimise the development potential of SHD and formulate a development scheme for a Comprehensive Residential and Commercial Development (the Project) which forms the basis of the Environmental Impact Assessment (EIA) Report.  A new Siu Ho Wan Station (SHO) has been proposed along the Tung Chung Line (TCL) to meet the transportation needs of the development and enable building of a sustainable community.

1.1.1.5           In accordance with the requirements of Section 5(1) of the EIAO, a Project Profile (No. PP-542/2016) for the Project was submitted to the Director of Environmental Protection (DEP) for application for an EIA Study Brief on 20 July 2016. Pursuant to Section 5(7)(a) of the EIAO, the DEP issued a Study Brief (No.: ESB-294/2016 dated 1 September 2016) for the EIA study.

1.2                          Purpose of the Manual

1.2.1.1           The purpose of this Environmental Monitoring and Audit (EM&A) Manual is to:

·         Guide the set-up of an EM&A programme for the Schedule 2 Designated Project (DP) (See Section 2.2) elements to ensure compliance with the EIA recommendations;

1.2.1.2           This Manual outlines the auditing programme for the construction and operation of the proposed Project and provides systematic procedures for auditing and minimising environmental impacts.

1.2.1.3           Hong Kong environmental regulations and the Hong Kong Planning Standards and Guidelines (HKPSG) have served as environmental standards and guidelines in the preparation of this Manual. In addition, this EM&A Manual has been prepared in accordance with the requirements stipulated in Annex 21 of the Technical Memorandum on the EIA Process (EIAO-TM).

1.2.1.4           This Manual contains the following information.

·         Responsibilities of the Contractor, the Engineer or Engineer’s Representative (ER), Environmental Team (ET), and the Independent Environmental Checker (IEC) under the context of EM&A;

·         Project organisation for the EM&A works;

·         The basis for, and description of the broad approach underlying the EM&A programme;

·         Details of the methodologies to be adopted, including all laboratories and analytical procedures, and details on quality assurance and quality control programme;

·         Requirements for reviewing pollution sources and working procedures required in the event of non-compliance with the environmental criteria and complaints; and

·         Requirements for presentation of environmental auditing data and appropriate reporting procedures.

1.2.1.5           This EM&A Manual is a dynamic document that should be reviewed regularly and updated as necessary during the construction and operation of the Project. The Contractor should review the mitigation measures and implementation schedule related to the ultimate Sewage Pumping Station (SPS) with respect to the design developments and construction methodology.

 

2                                Project Description

2.1                          General Description of the Project

2.1.1.1           Section 2 of the EIA Report has described the approaches adopted to avoid and minimise various environmental impacts throughout the design process. The final design has therefore been taken forward as the basis for this EIA to demonstrate that all statutory requirements under EIA Study Brief (ESB-294/2016) and the Environmental Impact Assessment Ordinance (EIAO) are complied with. A brief summary of key elements of the Project is given below:

·            Topside development including podium deck, residential towers, schools, transport, utility and other supporting facilities;

·            upgrading of the sewerage network, including sewage pipes to Siu Ho Wan Sewage Treatment Works (SHWSTW), with installation of new sewage pumping stations to cater for sewage generated by the Project;

·            A new Siu Ho Wan Station (SHO) and the associated track works;

·            Railway depot replanning works within the existing site boundary; and;

·            Construction of concrete slab within the existing depot for podium decking and property enabling works for the topside development.

2.1.1.2           After the issue of EIA Study Brief (ESB-294/2016), further design development has been evolved to streamline the implementation strategy.  According to the latest strategy, the key elements to be implemented in this Project only include the SHD Topside Development and the upgrading of the sewerage networks with installation of new sewage pumping station and construction of rising mains.  Other key elements including the railway depot replanning, construction of concrete slab above the depot, and the new SHO and the associated track works will be addressed in another EIA report for Siu Ho Wan Station and Siu Ho Wan Depot Replanning Works (Railway EIA), which would be submitted separately for approval under the Environmental Impact Assessment Process of the EIAO. Nevertheless, the relevant information and assessment results relating to SHO and the associated track works have been suitably included to fulfil the requirements in ESB-294/2016.

2.1.1.3           The Project would also include the eastern connection access on Sham Shui Kok Drive and the western access via Tai Ho Wan Interchange. The eastern connection access on Sham Shui Kok Drive is an at-grade road of about 1000m while the western access via Tai Ho Interchange is a short viaduct of approximately 50m long.

2.1.1.4           The location of the proposed SHD Topside Development is shown in Figure 2.1 together with its nearby infrastructure works. The development scheme of the proposed comprehensive residential and commercial development atop Siu Ho Wan Depot is also given in Figure 2.2.

2.2                          Designated Project

2.2.1.1           The Comprehensive Residential and Commercial Development atop Siu Ho Wan Depot is a Designated Project (DP) under Item 1 Schedule 3 of EIAO – Engineering feasibility study of urban development projects within a study area covering more than 20ha or involving a total of population of more than 100,000.

2.2.1.2           It comprises the following which are classified as Designated Projects (DPs) as per Schedule 2, Part I of the EIAO.

·               Item F.3(b) – A sewage pumping station with an installed capacity of more than 2000m3 per day and a boundary of which is less than 150m from an existing or planned residential area or educational institution (i.e. ultimate sewage pumping station);

·               Item A.2 – Railway Station (i.e SHO and associated trackworks on AEL/TCL); and

·               Item A.4 – A railway siding, depot, maintenance workshop, marshalling yard or goods yard (i.e. operation of SHD).

2.2.1.3           According to the latest design, the sewage generated by the Project will be conveyed to Siu Ho Wan Sewage Treatment Works.  An ultimate sewage pumping station will be required to provide sufficient pressure head for sewage delivery and it will be located at the eastern edge of the site boundary. According to Section 8 of the EIAO-TM, this EM&A Manual is only applicable to the above Schedule 2 DP element.

2.2.1.4           Schedule 2 DPs Item A.2 and Item A.4  are railway related DPs which will be separately covered in Railway EIA to be submitted for approval under the EIAO in order to streamline for project implementation and for the ease of reference of the public. Details of EM&A Programme for Schedule 2 DPs Item A.2 and Item A.4 are discussed in the Railway EM&A Manual, whereas, this EM&A Manual covers Schedule 2 DP Item F.3(b) mentioned in Section 2.2.1.2.

2.3                          Tentative Implementation Programme

2.3.1.1           For the ultimate SPS which is a Schedule 2 DP element, its tentative construction period would commence from Q3 2023 until Q4 2024.

4                                Air Quality

4.1                          Introduction

4.1.1.1           The EIA has considered the potential air quality impacts during the construction and operational phases of the ultimate SPS.

4.1.1.2           Based on the assessment results, no adverse impact from the ultimate SPS is anticipated with the implementation of regular watering and other good site practices as stipulated in Air Pollution Control (Construction Dust) Regulation. Nevertheless, dust monitoring and regular site environmental audit are still recommended to check the implementation of the regular watering and good site practices.

4.2                          Mitigation Measures

4.2.1                  Construction Phase

4.2.1.1           During the construction phase, regular watering and other good site practices should be implemented. All the recommended good practices are summarized in the Environmental Mitigation Implementation Schedule (EMIS) in Appendix 4.1.

4.2.2                  Operational Phase

4.2.2.1           During operational phase, the EIA Report has recommended odour control measures including enclosure of odour sources, maintaining of negative pressure within the facilities, regular maintenance of deodouriser, for the ultimate SPS. An odour removal efficiency of 95% should be achieved.

4.3                          Environmental Monitoring and Site Audit Requirements

4.3.1                  Construction Phase

Air Quality Parameters

4.3.1.1           As discussed in the EIA Report, while adverse dust impact is not anticipated during the construction phase after the implementation of mitigation measures such as regular watering, dust monitoring is still recommended as a good practice to be conducted throughout the construction period of the ultimate SPS. 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 action taken to rectify the situation.

They shall ensure that sufficient number of HVSs with an appropriate calibration kit is available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. The HVSs shall be equipped with an electronic mass flow controller and be calibrated against a traceable standard at regular intervals. All the equipment, calibration kit, filter papers, etc., shall be clearly labelled.

4.3.1.6           Initial calibration of dust monitoring equipment shall be conducted upon installation and thereafter every six months. The transfer standard shall be traceable to the internationally recognized primary standard and be calibrated annually. The calibration data should be properly documented for future reference by IEC. All the data should be converted into standard temperature and pressure condition.

4.3.1.7           The flow-rate of the sampler before and after the sampling exercise with the filter in position shall be verified to be constant and be recorded in the data sheet as mentioned in Appendix 4.2.

4.3.1.8           If the ET proposes to use a direct reading dust meter to measure 1-hour TSP levels, they shall submit sufficient information to the IEC to prove that the instrument is capable of achieving a comparable results to the HVS. The instrument should also be calibrated regularly, and the 1-hour sampling shall be determined periodically by the HVS to check the validity and accuracy of the results measured by direct reading method.

4.3.1.9           Wind data monitoring equipment shall also be provided and set up for logging wind speed and wind direction near the dust monitoring locations. The equipment installation location shall be proposed by the ET and agreed with the IEC. For installation and operation of wind data monitoring equipment, the following points shall be observed:

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

·               be close to the major site activities which are likely to have air quality impacts;

·               be close to 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.

4.3.1.19      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, must 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.

4.3.1.20      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.

Baseline Monitoring

4.3.1.21      Baseline monitoring shall be carried out at all of the designated monitoring location (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 one-hour sampling should also be done at least 3 times per day at each monitoring station.

4.3.1.22      During the baseline monitoring, there should not be any major construction or dust generation activities in the vicinity of the monitoring station. 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.

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

4.3.1.24      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.

4.3.1.25      General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources should be 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.

Impact Monitoring

4.3.1.26      The ET shall carry out impact monitoring during major construction activities for the ultimate SPS undertaken within a radius of 500m from the monitoring station. 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. 

4.3.1.27      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.

Action and Limit Levels

4.3.1.28      The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring. 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.

4.3.2                  Operational Phase

4.3.2.1           With the implementation of mitigation measures as stated in the EMIS (Appendix 4.1), operational phase impact is not anticipated.  Hence monitoring and audit requirements are not required.

 

5                                Noise

5.1                          Introduction

5.1.1.1           The EIA Report has considered the potential noise impacts during both the construction and operational phases of the ultimate SPS.

5.1.1.2           Based on the assessment results, adverse impact from the ultimate SPS is not anticipated with the implementation of the proposed noise mitigation measures.

5.2                          Mitigation Measures

5.2.1                  Construction Phase

5.2.1.1           The EIA Report has recommended construction noise mitigation measures including use of quiet plant and temporary noise barriers, etc. All the proposed mitigation measures are summarized in the EMIS in Appendix 4.1.

5.2.2                  Operational Phase

Fixed Noise

5.2.2.1           For the proposed noise sources, such as louvers, which are located near to existing and planned Noise Sensitive Receivers (NSRs), the following noise mitigation measures shall be considered:

·               All the pumps should be enclosed inside building structures;

·               Proper selection of quiet plant aiming to reduce the tonality at NSRs;

·               Installation of silencer / acoustic enclosure / acoustic louver for the exhaust of ventilation system;

·               Openings of ventilation systems should be located away from NSRs as far as practicable.

5.3                          Environmental Monitoring and Site Audit Requirements

5.3.1                  Construction Phase

5.3.1.1           Given adverse construction noise impacts are not anticipated and the construction of the ultimate SPS will be completed before the population intake of the proposed development, noise monitoring for construction noise is not necessary during the construction phase. However, regular audits and site inspections at least once per week should be carried out during construction phase by the ET to ensure that the mitigation measures recommended in the EIA Report and EMIS in Appendix 4.1 are properly implemented by the Contractor.

5.3.2                  Operational Phase

5.3.2.1           The Contractor should carry out a fixed noise commissioning test for planned fixed noise at the ultimate SPS before its operation. The test should be carried out by a qualified person possessing at least 7 years of noise control experience and a corporate membership of Hong Kong Institute of Acoustic or equivalent. The Contractor should implement all necessary measures to ensure compliances with the noise standards stipulated in the NCO for fixed plant operations.

 

6                                Water Quality

6.1                          Introduction

6.1.1.1           The EIA Report has assessed the water quality impacts associated with the ultimate SPS. According to the current design, the construction works would be land-based and there would not be any marine works. Good site practices in accordance to Practice Note for Professional Persons on Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC PN 1/94) would be implemented and proper temporary sanitary facilities (e.g. portable chemical toilet) would be provided to properly collect the on-site sewage generated from the construction workers. Various mitigation measures are proposed. With proper implementation of those mitigation measures, it is anticipated that there would be no residual adverse water quality impact.

6.2                          Mitigation Measures

6.2.1                  Construction Phase

6.2.1.1           The EIA Report has recommended mitigation measures including good site practices to control construction site runoff. All the mitigation measures are summarised in EMIS in Appendix 4.1. These mitigation measures also include practices to handle sewage from workforce such as provision of portable chemical toilets.

6.2.2                  Operational Phase

6.2.2.1           During the operation phase, recommended provisions are suggested for the ultimate SPS to minimize the chance of emergency discharge. The recommended provisions including 100% standby pumping capacity, twin rising mains, emergency storage facilities up to 3-hour ADWF capacity, are listed in EMIS in Appendix 4.1.

6.3                          Environmental Monitoring and Site Audit Requirements

6.3.1                  Construction Phase

6.3.1.1           Due to absence of anticipated adverse impacts on water quality, environmental monitoring of water quality is not recommended during construction phase. Regular audits and site inspections at least once per week should be carried out during construction phase by the ET to ensure that the mitigation measures recommended in the EIA Report and EMIS in Appendix 4.1 are properly implemented by the Contractor.

6.3.1.2           A compliance audit for effluent discharge against valid discharge license should be carried out through scheduled on-site measurement in accordance with the monitoring frequency and parameter stipulated in the Water Pollution Control Ordinance (WPCO).

6.3.1.3           As the details in Appendix 4.1 shows, the mitigation measures during construction phase include the practices which can reduce the potential water impact due to construction site runoff in accordance to Practice Note for Professional Persons on Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC PN 1/94).

6.3.1.4           During the construction phase, the impacts of sewage from workforce should be mitigated by provision of portable chemical toilets and posting of notices to remind workers not to discharge any sewage or wastewater into the nearby environment.

6.3.2                  Operational Phase

6.3.2.1           With the implementation of additional provision and enhancement of sewage pumping stations as stated in the EMIS (Appendix 4.1), operational phase impact is not anticipated.  Hence, monitoring and audit requirements are not required. The additional provisions and enhancement of sewage pumping stations include standby pumping capacity, dual-feed power supply for each SPS, provision of emergency storage tank, monitoring and control system 24-7 emergency repair service in case of emergency situation and regular inspection by qualified personnel are detailed in Appendix 4.1.

 

7                                Sewerage and Sewage Treatment Implications

7.1                          Introduction

7.1.1.1           An assessment of potential impacts due to sewage arising from the ultimate SPS, is assessed in Section 6 of the EIA Report. The EIA Report reviews the existing and planned sewerage network. With the planned sewerage network connecting to the existing Siu Ho Wan Sewage Treatment Plant, it is anticipated that there would be no adverse impacts due to sewage arising from the proposed Project.

7.2                          Mitigation Measures

7.2.1                  Operational Phase

7.2.1.1           Due to the ecological consideration of The Brothers Marine Park in The Brothers (islands), the provision of twin rising mains, adoption of high density polyethylene (HDPE) or ductile iron pipe and mitigation measures to minimize the chances of emergency discharge are proposed to enhance the sewerage network reliability and minimise environmental impacts due to system failure or in case of emergency situations during the operation phase. Chances of emergency discharge would be minimised with the implementation of following mitigation measures:

·               100% standby pumping capacity within ultimate SPS, with spare pump up to 50% pumping capacity stockpiled for any emergency use.  The standby pump will be automatically take off the failed duty pump;

·               dual-feed power supply;

·               emergency storage tank providing up to 3-hours ADWF capacity at the ultimate SPS. This emergency storage will be provided adjacent to the wet well chamber.  The inlet of the emergency storage will be at the same level as the invert level of incoming pipe of wet well chamber.    It is noted that this emergency storage will be provided at the ultimate SPS located at ground level of the eastern end of the proposed development and will consider all sewage flow from the development;

·               Monitoring and Control System (MACS) providing real-time notification of alert signal in emergency situation;

·               Project Proponent’s term contractor to provide 24-7 emergency repair service in case of emergency situation; and

·               Qualified personnel appointed by Project Proponent carrying out regular inspection, routine maintenance and repairing of the facilities and equipment.

7.2.1.2           The details of these measures are described in EMIS in Appendix 4.1.

7.3                          Environmental Monitoring and Site Audit Requirements

7.3.1                  Operational Phase

7.3.1.1           With the implementation of mitigation measures as stated in the EMIS (Appendix 4.1), operational phase impact is not anticipated.  Hence, monitoring and audit requirements are not required.

 

8                                Waste Management

8.1                          Introduction

8.1.1.1           The quantity and timing for the generation of waste during the construction phase have been estimated. Measures including the opportunity for on-site sorting, reusing excavated materials etc., are devised in the construction methodology to minimise the surplus materials to be disposed off-site. Proper disposal of chemical waste should be via a licensed waste collector.

8.2                          Mitigation Measures

8.2.1                  Construction Phase

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

8.2.1.2           Waste will be handled in accordance with relevant legislation and guidelines and with the implementation of the proposed mitigation measures, no adverse environmental impacts from waste management are anticipated. EM&A requirements are 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 environmentally acceptable manner; and

·         To encourage the reuse and recycling of material.

8.2.1.3           A trip-ticket system should be operated to monitor all movements of C&D materials and chemical wastes which will be collected by a licensed collector to a licensed facility for final treatment and disposal. Recommendations have been made to ensure proper treatment and proper disposal of these wastes in the EIA Report and summarised in the EMIS in Appendix 4.1.

8.2.1.4           All dump trucks engaged on site 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.

8.2.2                  Operational Phase

8.2.2.1           The types and quantities of waste that would be generated during the operational phase have been assessed. General refuse generated from the ultimate  SPS should be collected with lidded bins and at least daily collection should be arranged by the waste collector as stated in the EIA Report and EMIS. If any chemical waste is to be generated from the operation of the ultimate SPS, the operator shall register as a Chemical Waste Producer with EPD and manage the chemical waste in accordance with Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C). With proper management, it is anticipated there would not be any insurmountable impacts during the operational phase.

8.3                          Environmental Monitoring and Site Audit Requirements

8.3.1                  Construction Phase

8.3.1.1           The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant license / 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 Producer Registration;

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

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 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 ultimate SPS.  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 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 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.

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 for vetting to ensure sufficient environmental protection and pollution control measures have been included.  The Environmental Mitigation Implementation schedule (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 legislations have 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 licences / permits under the environmental protection laws, and copies of all valid licences / 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 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 may 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.

14.3.1.2      In case the Contractor needs to update the mitigation measures and/or the project implementation schedule as a result of alternative construction method(s) or other condition (e.g. site constraint(s)), the ET shall also review the latest recommendation of mitigation measures and/or project implementation schedule by submission of a Proactive Environmental Protection Proforma as shown in Appendix 14.1.   The IEC should verify the Proforma and conduct audit to confirm proper implementation of the alternative measures.

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;
