1.                       INTRODUCTION

1.1                   Project Background

1.1.1             The Transport Department (TD) has reviewed the traffic conditions of Tsuen Wan Road (TWR) near Kwai Tsing Interchange (KT I/C) and considered that a section of the southbound carriageway of TWR between KT I/C and Kwai Chung Road (KCR) would deteriorate in the future years due to congestion that would occur during peak hours.  TD considers that there is a need to implement the Project to improve the road section to cope with the future traffic growth, and the scope comprises the following principal works elements:

·      Provision of an additional traffic lane for the southbound traffic between KT I/C upramp and KCR;

·      Modification of existing slip roads; and

·      Associated environmental mitigation measures, utility diversion, street lighting, traffic aids, traffic and control surveillance, drainage works, landscaping works and other related works.

1.1.2             AECOM Consulting Services Limited (formerly URS Hong Kong Ltd or Scott Wilson Ltd) was commissioned by the Civil Engineering and Development Department (CEDD) of the Government of the Hong Kong Special Administrative Region to undertake the investigation stage of Flyover from Kwai Tsing Interchange up-ramp to Kwai Chung Road (‘the Project’ refers hereinafter) under Agreement No. CE 8/2012 (HY).

1.1.3             The project is a Designated Project under the Environmental Impact Assessment Ordinance (EIAO).  An Environmental Impact Assessment (EIA) Study for the Project has been undertaken as part of the Assignment, in accordance with the EIA Study Brief (No. ESB-242/2012) and the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM).

1.2                   Project Scope and Programme

1.2.1             To fulfil future demand and to prevent traffic congestion in the future during peak traffic flow hour, an additional southbound lane (a separated viaduct) is introduced on TWR and connected to the existing lane on the west side of KCR with design speed of 70 km/hr.  The basis of design for this proposed flyover is to utilise the remaining capacity currently available on the two segregated KCR carriageways.  The proposed road works is shown in Figure 1.1 while proposed and associated works include:

·      Existing footbridge NF303 is to be demolished and be re-provided;

·      Existing Public Works Regional Laboratory will be affected;

·      Existing drainage reserve zone positioned alongside TWR will be affected;

·      Existing bus stop outside subway NS10A is to be relocated, and

·      Minor modification to the existing Kwai Chung Road involves removal of the existing planter, breaking and reinstating Kwai Chung Road with the new road marking.

2.                       AIR QUALITY IMPACT

2.1                   Introduction

2.1.1             The EIA study of this Project concluded that, with the implementation of sufficient dust suppression measures as stipulated under the Air Pollution Control (Construction Dust) Regulation and good site practices and proposed mitigation measures, adverse dust impact would not be anticipated at the Air Sensitive Receivers (ASRs) in the vicinity of the construction sites. 

2.1.2             However, in order to ensure that appropriate dust control measures are properly implemented and good construction site practices are adopted throughout the construction period, an EM&A program is proposed to be carried out during construction to monitoring the short-term impacts.

2.1.3             Air quality monitoring during the operation phase of this Project is considered not necessary as air quality impacts to the adjacent identified ASRs arising from the Project would be insignificant.

2.2                   Air Quality Parameters

2.2.1             Monitoring and audit of the Total Suspended Particulates (TSP) levels shall be undertaken by the ET Leader to ensure that any deteriorating air quality could be readily detected and timely action taken to rectify the situation.

2.2.2             1-hour and 24-hour TSP levels shall be measured to indicate the impacts of construction dust on air quality. The 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 ER, 1-hour TSP levels can be measured by direct reading methods which are capable of producing comparable results as that by the high volume sampling method, to indicate short event impacts.

2.2.3             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 2-1.  

2.3                   Monitoring Equipment

2.3.1             Monitoring and audit of the Total Suspended Particulates (TSP) levels shall be undertaken by the ET Leader to ensure that any deteriorating air quality could be readily detected and timely action taken to rectify the situation.

2.3.2             High volume sampler (HVS) in compliance with the following specifications shall be used for carrying out the 1-hr and 24-hr TSP monitoring:

·      0.6-1.7 m3/min (20-60 SCFM) adjustable flow range;

·      equipped with a timing/control device with ± 5 minutes accuracy for 24 hours operation;

·      installed with elapsed-time meter with ± 2 minutes accuracy for 24 hours operation;

·      capable of providing a minimum exposed area of 406 cm2 (63 in2);

·      flow control accuracy: ± 2.5% deviation over 24-hr sampling period;

·      equipped with a shelter to protect the filter and sampler;

·      incorporated with an electronic mass flow rate controller or other equivalent devices;

·      equipped with a flow recorder for continuous monitoring;

·      provided with a peaked roof inlet;

·      incorporated with a manometer;

·      able to hold and seal the filter paper to the sampler housing at horizontal position;

·      easy to change the filter; and

·      capable of operating continuously for 24-hr period. 

2.3.3             The ET Leader is responsible for provision of the monitoring equipment. He shall ensure that sufficient number of HVSs with an appropriate calibration kit are 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.

2.3.4             Initial calibration of dust monitoring equipment shall be conducted upon installation and thereafter at bi-monthly intervals. The transfer standard shall be traceable to the internationally recognised primary standard and be calibrated annually. The calibration data shall be properly documented for future reference by the concerned parties such as the IEC. All the data shall be converted into standard temperature and pressure condition.

2.3.5             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 down in the data sheet in Appendix 2-1.

2.3.6             If the ET Leader proposes to use a direct reading dust meter to measure 1-hr TSP levels, he shall submit sufficient information to the IEC to prove that the instrument is capable of achieving a comparable result as that the HVS and may be used for the 1-hr sampling. The instrument shall also be calibrated regularly, and the 1-hr sampling shall be determined periodically by HVS to check the validity and accuracy of the results measured by direct reading method.

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

·      the wind sensors shall be installed on masts at an elevated level 10m above ground so that they are clear of obstructions or turbulence caused by the buildings;

·      the wind data shall be captured by a data logger. The data recorded in the data logger shall be downloaded periodically for analysis at least once a month;

·      the wind data monitoring equipment shall be re-calibrated at least once every six months; and

·      wind direction shall be divided into 16 sectors of 22.5 degrees each.

2.3.8             In exceptional situations, the ET Leader may propose alternative methods to obtain representative wind data upon approval from the ER and agreement from the IEC.

2.4                   Laboratory Measurement / Analysis

2.4.1             A clean laboratory with constant temperature and humidity control, and equipped with necessary measuring and conditioning instruments, to handle the dust samples collected, shall be available for sample analysis, and equipment calibration and maintenance. The laboratory shall be HOKLAS accredited or other internationally accredited laboratory.

2.4.2             If a site laboratory is set up or a non-HOKLAS accredited laboratory is hired for carrying out the laboratory analysis, the laboratory equipment shall be approved by the ER in consultation with the IEC. Measurement performed by the laboratory shall be demonstrated to the satisfaction of the ER and the IEC. IEC shall conduct regular audit to the measurement performed by the laboratory to ensure the accuracy of measurement results. The ET Leader shall provide the ER with one copy of the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B for his reference.

2.4.3             Filter paper of size 8"x10" shall be labelled before sampling. It shall be a clean filter paper with no pin holes, and shall be conditioned in a humidity controlled chamber for over 24-hr and be pre-weighed before use for the sampling.

2.4.4             After sampling, the filter paper loaded with dust shall be kept in a clean and tightly sealed plastic bag. The filter paper is then returned to the laboratory for reconditioning in the humidity controlled chamber followed by accurate weighing by an electronic balance with a readout down to 0.1 mg. The balance shall be regularly calibrated against a traceable standard.

2.5                   Monitoring Locations

2.5.1             Three reprehensive Construction Dust Monitoring Locations are proposed in Table 2‑1 below and shown in Figure 2.1.

2.5.2             The status and locations of dust sensitive receivers may change after issuing this manual. If such cases exist, the ET Leader shall propose updated monitoring locations and seek approval from ER and agreement from the IEC.

2.5.3             When alternative monitoring locations are proposed, the following criteria, as far as practicable, shall be followed:

·      at the site boundary or such locations close to the major dust emission source;

·      close to the sensitive receptors; and

·      take into account the prevailing meteorological conditions.

2.5.4             The ET Leader shall agree with the ER in consultation with the IEC the position of the HVS for 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 shall be provided;

·      no two samplers shall be placed less than 2 metre 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 metres of separation from walls, parapets and penthouses is required for rooftop samplers;

·      a minimum of 2 metre 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 metres from the dripline;

·      any wire fence and gate, to protect the sampler, shall 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. 

2.6                   Baseline Monitoring

2.6.1             The ET Leader shall carry out baseline monitoring at all of the designated monitoring locations for at least 14 consecutive days prior to the commissioning of the construction works to obtain daily 24-hr TSP samples. 1-hr sampling shall also be done at least 3 times per day while the highest dust impact is expected. A summary of the requirements for the baseline monitoring is shown in Table 2‑2.

2.6.2             Before commencing the baseline monitoring, the ET leader shall inform the IEC of the baseline monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

2.6.3             During the baseline monitoring, there shall not be any construction or dust generation activities in the vicinity of the monitoring stations.

2.6.4             In case the baseline monitoring cannot be carried out at the designated monitoring locations during the baseline monitoring period, the ET Leader shall carry out the monitoring at alternative locations which can effectively represent the baseline conditions at the impact monitoring locations. The alternative baseline monitoring locations shall be approved by the ER and agreed with the IEC.

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

2.6.6             Baseline checking of ambient TSP levels shall be carried out every three months at each monitoring location when no dusty works activities are in operation. If the ET considers that significant change in the ambient conditions has taken place, a repeat of the baseline monitoring may be carried out to update the baseline levels. The revised baseline levels and, in turn, the air quality criteria shall be agreed with the IEC and EPD.

2.7                   Impact Monitoring

2.7.1             The ET Leader shall carry out impact monitoring during the course of the Works. For regular impact monitoring, the sampling frequency of at least once in every six-days, shall be strictly observed at all the monitoring stations for 24-hr TSP monitoring. For 1-hr TSP monitoring, the sampling frequency of at least three times in every six-days shall be undertaken when the highest dust impact occurs. A summary of the requirements for the impact monitoring is shown in Table 2‑3.

2.7.2             Before commencing the baseline monitoring, the ET leader shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the impact monitoring results.

2.7.3             The specific time to start and stop the 24-hr TSP monitoring shall be clearly defined for each location and be strictly followed by the field operator.

2.7.4             In case of non-compliance with the air quality criteria, more frequent monitoring exercise, as specified in the Action Plan, shall be conducted within 24 hours after the result is obtained. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified.

2.8                   Event and Action Plan for Air Quality

2.8.1             The baseline monitoring results from the basis for determining the air quality criteria for the impact monitoring. The ET Leader shall compare the impact monitoring results with air quality criteria set up for 1-hour TSP.  Table 2-4 shows the air quality criteria, namely Action and Limit Levels to be used.

2.9                   Dust Mitigation Measures

2.9.1             The EIA report has recommend dust control and mitigation measures. The contractor shall be responsible for the design and implementation of these measures.

2.9.2             The dust suppression measures as stipulated under the Air Pollution Control (Construction Dust) Regulation and good site practices is recommended and presented in Appendix 1-2 in order to further minimize the construction dust generated including:

·                Every temporary access road shall be paved with concrete, bituminous materials, hardcores or metal plates, and kept clear of dusty materials; or sprayed with water or a dust suppression chemical so as to maintain the entire road surface wet.

·                Any stockpile of dusty materials shall be covered entirely by impervious sheeting, placed in an area sheltered on the top and the 3 sides, or sprayed with water or a dust suppression chemical so as to maintain the entire surface wet. The materials should be removed or backfilled or reinstated where practicable within 24 hours of the excavation or unloading.

·                All dusty materials shall be sprayed with water or a dust suppression chemical immediately prior to any loading, unloading or transfer operation so as to maintain the dusty materials wet.

·                Vehicles used for transporting dusty materials should be covered with tarpaulin or similar material, and the cover should extend over the edges of the sides and tailboards.

·                Vehicle wheel washing facilities should be provided at each construction site exit. Immediately before leaving a construction site, every vehicle shall be washed to remove any dusty materials from its body and wheels.

·                Where a vehicle leaving a construction site is carrying a load of dusty materials, the load shall be covered entirely by clean impervious sheeting to ensure that the dusty materials do not leak from the vehicle.

·                The speed of vehicles on unpaved road within the site should be controlled to about 10 km/hr.

·                Routing of vehicles and positioning of construction plants should be arranged at maximum possible distances from the sensitive receivers.

·                Every stock of more than 20 bags of cement and dry pulverized fuel ash (PFA) shall be covered entirely by impervious sheeting or placed in an area sheltered on the top and the 3 sides.

·                Loading, unloading, transfer, handling or storage of large amount of cement or dry PFA should be carried out in a totally enclosed system or facility, and any vent or exhaust should  be fitted with the an effective fabric filter or equivalent air pollution control system.

·                Exposed earth shall be properly treated by compaction, turfing, hydroseeding, vegetation planting or sealing with latex, vinyl, bitumen, shotcrete or other suitable surface stabilizer within 6 months after the last construction activity on the construction site or part of the construction site where the exposed earth lies. 

 

2.9.3             If the above measures are not sufficient to restore the air quality to acceptable levels upon the advice of ET Leader, the Contractor shall liaise with the ET Leader on some other mitigation measures, propose to ER for approval, and implement the mitigation measures.

2.10               Site Audit Requirements

2.10.1         The implementation of regular site audits aims to ensure the mitigation measures recommended in the EIA report to be properly undertaken during the construction phase of this Project. It can also provide an effective control of any mal-practices and, therefore, achieve the continual improvement of the environmental performance on-site.

2.10.2         Inspections of the construction activities, works sites and works areas should be conducted by the Contractor at least on a weekly basis to ensure the mitigation measures to be properly implemented.

2.10.3         Site audits should be carried out by the Engineer, ET and Contractor, and should be based on the mitigation measures for the air pollution control as recommended in Appendix 1-2. In the event that the recommended mitigation measures are not fully or properly implemented, the Contractor should report the deficiency to the Engineer and ET. The appropriate action will need to be taken by the Contractor:

·      Investigate the problems and causes;

·      Discuss a remedial and corrective proposal with the Engineer and ET;

·      Take action according to the action notes agreed with the Engineer;

·      Implement the remedial and corrective action immediately;

·      Re-Inspect the site conditions upon the completion of the remedial and corrective action; and

·      Record the event.

3.                       NOISE IMPACT

3.1                   Introduction

3.1.1             Based on assessment results in the EIA report, construction noise exceedance at NSRs is anticipated for the noise criteria during examination period even if mitigation measures are properly implemented. Regular noise monitoring should be carried out at representative NSRs.

3.1.2             Road traffic noise monitoring is recommended at representative NSRs during the first year of the road opening.

3.2                   General Monitoring Requirement and Equipment

3.2.1             As referred to in the Technical Memorandum (TM) issued under the Noise Control Ordinance (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 1.0dB. 

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

3.2.3             The ET Leader is responsible for the provision, installation, operation, maintenance and dismantling of the monitoring equipment.  He shall ensure that sufficient noise monitoring 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.

3.2.4             The monitoring station shall normally be at a point 1m from the exterior of the sensitive receiver's 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 +3dB(A) shall be made to the free-field measurements. The ET Leader shall agree with the ER/IEC on the monitoring positions 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.

3.3                   Noise Parameters for Construction Noise

3.3.1             The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq).  Leq (30 min) shall be used as the monitoring parameter for the time period between 0700-1900 hours on normal weekdays.  For all other time periods, Leq (5 min) shall be employed for comparison with the NCO criteria.

3.3.2             As supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference. Appendix 3-1 shows a sample data record sheet for construction noise monitoring.

3.4                   Monitoring Locations for Construction Noise

3.4.1             Noise exceedance is anticipated at the following existing NSRs under unmitigated scenario:

·      Lingnan Dr. Chung Wing Kong Memorial Secondary School

·      Lai King Catholic Secondary School

·      Fung King House

·      Ming King House

·      HKEAA-Lai King Assessment Centre

3.4.2             Three reprehensive Noise Monitoring Locations (NML) are proposed in Table 3-1 below and shown in Figure 3.1.

3.4.3             The status and locations of noise sensitive receivers may change after issuing this manual.  In this event, the ET Leader shall propose updated monitoring locations and seek approval from ER and the IEC and agreement from EPD of the proposal.

3.4.4             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.

3.5                   Baseline Monitoring for Construction Noise

3.5.1             Baseline noise measurement shall be conducted to determine the background noise before commencement of work. Daily measurement of A-weighted levels Leq, L10 and L90 shall be conducted for at least two weeks. Daily sampling periods should include: (i) between 0700 and 1900 hours; (ii) between 1900 and 2300 hours; and (iii) between 2300 to 0700 hours of next day. Each of the daily sampling periods shall include 30 minutes (six consecutive Leq(5min) readings). A schedule on the baseline monitoring shall be submitted to the ER/IEC for approval before the monitoring starts.

3.5.2             During the baseline monitoring, there should be no major construction activities near the monitoring stations.

3.5.3             Alternative baseline NML that can give representative baseline result may be proposed for ER and IEC’s approval with justifications.

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

3.6                   Impact Monitoring for Construction Noise

3.6.1             Noise monitoring shall be carried out at all the designated monitoring locations.  The monitoring frequency shall depend on the scale of the construction activities.  The following is an initial guide on the regular monitoring frequency for each station on a per week basis when noise generating activities are underway:

·      One set of measurements between 0700-1900 hours on normal weekdays (six consecutive Leq/5min readings);

·      One set of measurements between 1900-2300 hours;

·      One set of measurements between 2300-0700 hours of next day; and

·      One set of measurements between 0700-2300 hours on holidays.

3.6.2             For the latter 3 sets of measurements specified in Section 3.6.1 above, one set of measurements shall at least include 3 consecutive Leq(5min) results.

3.6.3             In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Action Plan in Section 3.7 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.

3.7                   Event and Action Plan

3.7.1             Noise Standards for Daytime Construction Activities are specified under EIAO-TM. The Action and Limit levels for construction noise are defined in Table 3-2.  Should non-compliance of the criteria occur, action in accordance with the Action Plan in Table 3-3 shall be carried out. Necessary mitigation measures are shown in Section 3.8. Timing and responsibilities for the implementation of mitigation measures are shown in Implementation Schedule in Appendix 1-2.

3.8.3             Good Practices are also recommended as follow:

·      use of well-maintained and regularly-serviced plant during the works;

·      plant operating on intermittent basis should be turned off or throttled down when not in active use;

·      plant that is known to emit noise strongly in one direction should be orientated to face away from the NSRs;

·      silencers, mufflers and enclosures for plant should be used where possible and maintained adequately throughout the works;

·      where possible fixed plants should be sited away from NSRs; and

·      stockpiles of excavated materials and other structures such as site buildings should be used effectively to screen noise from the works.

3.8.4             If the above measures are not sufficient to restore the construction noise quality to acceptable levels, upon the advice of ET Leader, the Contractor shall liaise with the ET Leader on alternative mitigation measures, propose such measures to the ER/IEC for approval, and implement the mitigation measures. 

3.8.5             Implementation status and the effectiveness of mitigation measures shall be audited through regular site inspection.

3.9                   Parameters for Operational Traffic Noise

3.9.1             The ET should also carry out monitoring of road traffic noise after the works under Contract are completed and put into operation.  The road traffic noise during operation of the Project should be measured in terms of the A-weighted equivalent of L10 (1-hr). During the traffic noise measurement, traffic count should also be undertaken concurrently. Supplementary information for data auditing and statistical results such as Leq and L90 should also be obtained for reference.

3.9.2             Noise measurements shall not be made in fog, rain, wind with a steady speed exceeding 5m/s or wind with gusts exceeding 10m/s.  The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in m/s.

3.10.2         The status and locations of noise sensitive receivers may change after issuing this manual.  In this event, the ET Leader shall propose updated monitoring locations and seek approval from ER/IEC and agreement from EPD of the proposal.

3.10.3         When alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria in that they should be:

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

·      Close to the 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.

3.11               Baseline Monitoring

3.11.1         No baseline monitoring is required for Operational Road Traffic Noise.

3.12               Operational Traffic Noise Impact Monitoring

3.12.1         Traffic noise monitoring shall be carried out twice at representative NSRs at 6-month intervals within one year of the road opening. The following is an initial guide on the traffic noise monitoring requirements during the operational phase:

·      One set of measurements at the morning traffic peak hour on normal weekdays;

·      One set of measurements at the evening traffic peak hour on normal weekdays;

·      A concurrent census of traffic flow and percentage heavy vehicle shall be conducted for the road and the existing road network in the vicinity of each measuring point;

·      Average vehicle speed estimated for Project road and the existing road network in the vicinity of each measuring points; and

·      The two sets of monitoring data should be obtained within the first year of operation.

3.12.2         Measured noise levels should be compared with predicted noise levels by applying appropriate conversion corrections to allow for the traffic conditions at the time of measurement.  Appendix 3-2 shows a sample data record sheet for operational noise monitoring.

3.12.3         Each set of measurements shall include three measurements of 30 minutes. The parameters L10, Leq, L90 and Lmax will be recorded for data auditing and reference.

3.13               Event and Action Plan for Traffic Noise

3.13.1         For traffic noise, the measured/monitored noise levels shall be compared with the predicted results and the predicted traffic flow conditions (calculated noise levels based on concurrent traffic census obtained).  In case discrepancies are observed, explanation shall be given to justify the discrepancies.

4.                       WATER QUALITY IMPACT

4.1                   Introduction

4.1.1             The implementation of proper mitigation measures in place as recommended in the EIA report, adverse water quality impact would not be anticipated to the identified Water Sensitive Receivers (WSRs) during the construction and operation phases of this Project. As such, regular inspections of construction activities, works sites and works areas should be conducted to ensure that the recommended mitigation measures are properly implemented.

4.2                   Monitoring Requirements

Construction Phase

4.2.1             No surface water quality monitoring would be required during the construction phase. To avoid any potential water quality impacts arising from the construction activities, regular site audits should be conducted to ensure the recommended mitigation measures are properly implemented.

Operation Phase

4.2.2             No adverse water quality impact would be anticipated during the operation phase, provided that all mitigation measures recommended in the EIA report are properly implemented. Therefore, water quality monitoring and auditing are not required during the operation phase.

4.3                   Mitigation Measures

4.3.1             The recommended mitigation measures for water quality impacts are presented the implementation schedule in Appendix 1-2 of this EM&A Manual. In the event of complaints or non-compliances, the ET, ER and Contractor should review the effectiveness of these mitigation measures, design alternatives or additional mitigation measures as appropriate. The Contractor should propose the corrective action to the ER for approval, and implement them accordingly. 

4.4                   Audit Requirements

4.4.1             The implementation of regular site audits aims to ensure the mitigation measures recommended in the EIA report to be properly undertaken during the construction phase of this Project. It can also provide an effective control of any mal-practices and, therefore, achieve the continual improvement of the environmental performance on-site. Site audits should include both site inspections and compliance audits.

Site Inspection

4.4.2             Inspections of the construction activities, works sites and works areas should be conducted by the Contractor at least on a weekly basis to ensure the mitigation measures to be properly implemented. During operation, the system should be properly maintained and cleaned regularly to ensure good service condition in which Highway Department will be responsible for the maintenance of road drains.

4.4.3             Site audits should be carried out by the ER, ET and Contractor, and should be based on the mitigation measures for the water pollution control as recommended in Appendix 1-2. In the event that the recommended mitigation measures are not fully or properly implemented, the Contractor should report the deficiency to the ER and ET. The appropriate action will need to be taken by the Contractor:

·      Investigate the problems and causes;

·      Issue action notes to the Contractor who is responsible for the works;

·      Implement the remedial and corrective action immediately;

·      Re-inspect the site conditions upon the completion of the remedial and corrective action; and

·      Record the event and discuss with the Contractor for preventive actions.

Compliance Audits

4.4.4             Compliance audits are to be undertaken to ensure that a valid Water Pollution Control Ordinance (WPCO) discharge license has been issued by the EPD prior to the discharge of effluent from the construction activities of this Project site.  Monitoring of the quality of the treated effluent from the works areas should be carried out in accordance with the WPCO discharge license. The audit results reflect whether the effluent quality is in compliance with the discharge license requirements. In case of non-compliances, the following action should be taken:

·      The Contractor should notify the ER, ET and IEC;

·      The ER, ET and IEC should identify the sources of pollution and recommend and agree the appropriate mitigation measures for the Contractor;

·      The ER and ET should check the implementation status of the agreed mitigation measures by the Contractor;

·      The ET should increase the monitoring frequency until the effluent quality is in compliance with the requirements of the discharge license; and

·      The ET should record the non-compliances and propose preventive measures.

 

 


5.                       Waste Management Implication and Land Contamination

5.1                   Introduction

5.1.1             Regular auditing should be carried out by the ET during the construction phase of the Project to ensure wastes are being managed with the appropriate procedures or practices in accordance with relevant legislation and waste management guidelines as well as those recommended in this EIA Report. The audits will examine all aspects of waste management including waste generation, storage, recycling, transportation and disposal.

5.1.2             A Waste Management Plan (WMP), as part of Environmental Management Plan (EMP), should be prepared in accordance with ETWB TC(W) No.19/2005 and submitted to the ER for approval. The recommended mitigation measures should form the basis of the WMP. The monitoring and auditing requirement stated in ETWB TC(W) No.19/2005 should be followed with regard to the management of Construction and Demolition (C&D) Materials.

5.1.3             The Public Works Regional Laboratory of Tsuen Wan (Laboratory) has been identified as a chemical waste producer, which is a potential contaminated land use within the project boundary. The allocatee shall be responsible for the land contamination assessment of the Laboratory Site and ensure the Laboratory Site is free from contamination at the expiry of allocation and therefore any land contamination concern arising from past activities would have been remediated prior to the construction of the works.

5.1.4             With implementation of good site practice and design, land contamination at the Site arising from construction and operation phases of the Project as road upgrading works is not envisaged. , no EM&A for contaminated land is recommended.

5.2                   Mitigation Measures

5.2.1             With proper handling, collection, transportation and disposal of waste arising from the construction of the Project, it is anticipated that potential adverse environmental impacts would be avoided or minimised. During site inspections, the Engineer 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. The following waste management measures should be implemented by the Contractor:

·      The Contractor should be requested to submit an outline WMP prior to the commencement of construction work, in accordance with the ETWB TC(W) No.19/2005 so as to provide an overall framework of Waste Management and Reduction. The WMP should include:

-       Waste management policy;

-       Record of generated waste;

-       Waste reduction target;

-       Waste reduction programme;

-       Role and responsibility of waste management team;

-       Benefit of waste management;

-       Analysis of waste materials;

-       Reuse, recycling and disposal plans;

-       Transportation process of waste products; and

-       Monitoring and action plan.

·      The waste management hierarchy as provided in Section 6.6.4 of the EIA report and below should be strictly followed and applied in evaluating the waste management options in order to maximise the waste reduction and often reduce costs, for example, by controlling, reducing or eliminating over-ordering of construction materials. Records of quantities and locations of wastes generated, recycled and disposal should be properly documented. The hierarchy shall be as follows:

-       Avoidance and minimisation, i.e. avoiding or not generating waste through changing or improving practices and design;

-       Reuse of materials, thus avoiding disposal (generally with only limited reprocessing);

-       Recovery and recycling, thus avoiding disposal (although reprocessing may be required); and

-       Treatment and disposal, according to relevant laws, guidelines and good practice.

·      A trip-ticket system should be established in accordance with DevB TC(W) No. 6/2010 and Waste Disposal (Charges for Disposal of Construction Waste) Regulation in order to monitor the disposal of inert C&D Materials at public fill reception facilities and the remaining C&D Waste to landfills, and control fly-tipping. A trip-ticket system should be included as one of the contractual requirements and implemented by the Contractor. The ER should regularly audit the effectiveness of the system.

·      A recording system for the amount and locations of waste generated, recycled and disposed should be established. The Contractor should also provide proper training to workers regarding the appropriate concepts of site cleanliness and waste management procedures, e.g. waste reduction, reuse and recycling all the time.

·      If chemical wastes are to be produced at the construction site, the Contractor would be required to register with the EPD as a Chemical Waste Producer and to follow the guidelines stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Good quality containers compatible with the chemical wastes should be used, and incompatible chemicals should be stored separately. Appropriate labels should be securely attached on each chemical waste container indicating the corresponding chemical characteristics of the chemical waste (such as explosive, flammable, oxidizing, irritant, toxic, harmful, or corrosive).

·      The Contractor should use a licensed collector to transport and dispose of the chemical wastes, to either the Chemical Waste Treatment Centre at Tsing Yi, or another licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.

·      No waste should be burnt on-site. Disposal of waste at unlicensed location e.g. natural habitat should be prohibited. The Contractor should propose the final disposal sites in the EMP and WMP for approval before implementation.

5.3                   Audit Requirements

5.3.1             Regular audits and site inspection should be carried out by the ER, ET and Contractor to ensure that the recommended good site practices and other mitigation measure are 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 will verify the implementation status and evaluate the effectiveness of the mitigation measures.

 

6.                  LanDSCAPE and VISUAL IMPACTS

6.1                   Introduction

6.1.1             Landscape and Visual Impact Assessment in the EIA Report has identified and the possible impacts due to the Project.  It has also recommended mitigation measures for minimizing the impacts and for improving overall landscape and visual quality.  The Contractor to be employed by the Project Proponent will be responsible for the implementation of mitigation measures.  The Contractor should employ his own qualified landscape consultant (LC) for the construction and maintenance periods.

6.2                   Audit Requirements

6.2.1             The ET should be responsible for conducting regular review on the implementation of landscape and visual mitigation measures during the construction phase in accordance with the recommendations of the EIA Report.   

Construction Phase

6.2.2             The design, implementation and maintenance of landscape and visual mitigation measures should be checked bi-weekly by the ET to confirm that they are fully realised. Any potential conflicts between the proposed landscape measures, the Project works, and operational requirements should also be identified and resolved as early as possible.  Any changes to the mitigation measures should be incorporated in the detailed design.

Operational Phase

6.2.3             The ET should conduct site inspection to confirm that all operation phase mitigation measures are implemented in accordance with the Project design and the EIA recommendations.  Operational phase auditing will be restricted to the 12 months establishment works of the landscaping proposals.

6.3                   Mitigation Measures

6.3.1             The landscape and visual mitigation measures should be incorporated in the detailed design. The construction phase and operational phase mitigation measures proposed in the EIA are presented in Appendix 1-2. The construction phase mitigation measures should be adopted from the commencement of construction and should be in place throughout the entire construction period 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 on the date of commissioning of the Project.

6.3.2             Any potential conflicts between the proposed mitigation measures and any other project works and operational requirements should be resolved early and without compromising the intention of the mitigation measures.

 

 


7.                       LANDFILL GAS HAZARD

7.1                   Introduction

7.1.1             As the work boundary of the Project does not fall within the 250m Consultation Zone of the restored Gin Drinkers Bay Landfill. Therefore, the LFG hazard assessment is considered not necessary unless there is any possible change(s) on the alignment option in the future that the project/construction boundary shows encroachment on the Consultation Zone.

7.2                   Audit Requirements

7.2.1             The ET should regularly review the design and works area during construction phase.  If the works area has fallen within the 250m Consultation Zone of the restored Gin Drinkers Bay Landfill, all works within the consultation zone should be ceased, and the ET should inform EPD immediately and conduct the Landfill Gas Hazard Assessment.  The Landfill Gas Hazard Assessment must be approved by EPD before any works within the consultation zone commences again.  Appropriate mitigation measures should be provided and regular EM&A monitoring should be conducted when necessary.

 

 


8.                       CULTURAL HERITAGE

8.1                   Introduction

8.1.1             As no cultural heritage resource was identified within the Assessment Area of the Project, no impacts to cultural heritage are expected during both construction and operational phases of the Project. As a result, no mitigation measures would be required and, therefore, no EM&A is required.

8.2                   Audit Requirements

8.2.1             The ET should inform AMO immediately in case of discovery of antiquities or supposed antiquities during works within the project boundary.

 

 


9.                       ENVIRONMENTAL Auditing

9.1                   Site Inspection

9.1.2             The ET Leader should be responsible for formulating the environmental site inspection requirements, deficiency and action reporting system, and conducting the site inspection works. Within 21 days of the commencement of construction works, the ET Leader should submit a proposal for site inspection and deficiency and action reporting procedures to the Contractor for agreement, and to ER for approval. The ET Leader’s proposal for any rectification should be made known to the IEC.

9.1.3             Regular site inspections should be carried out at least once per week. The areas of inspection should not be limited to the environmental conditions, pollution control and mitigation measures within the works sites and works areas. It should also review the environmental conditions of that location that are beyond the boundary of the works sites and works areas likely to be affected directly or indirectly by the construction site activities. The ET Leader should make reference to the following information when conducting site inspection:

9.2.2             To ensure the works are in compliance with the contractual requirements, all method statements of major works should be submitted by the Contractor to the Engineer for approval and to the ET for vetting so as to ensure whether sufficient environmental protection and pollution control measures have been incorporated. The mitigation implementation schedule is included in Appendix 1-2.

9.2.3             The Engineer and ET should also review the progress and programme of the construction works in order to check that the relevant environmental legislation has not been violated and that any foreseeable potential for violating laws can be prevented.

9.2.4             The Contractor should provide the update of the relevant documents to the Engineer and ET, so that the checking can be carried out in good time. Such documents should at least include the updated works progress reports, works programme, application letters for environmental licenses/ permits, and all valid licenses/ permits. The Contractor’s site diary and environmental records should also be available for inspection by the relevant parties.

9.2.5             The Engineer and ET should advise the Contractor of any non-compliance with the contractual and legislative requirements on the environmental protection and pollution control so that they can timely take the follow-up action as appropriate. If it would still be insufficient to comply with the environmental protection and pollution control requirements, the Engineer and ET should provide further advice to the Contractor to take remedial action to resolve the problems.

9.2.6             Upon the receipt of such advice, the Contractor should undertake the immediate action to remedy the situation. The Engineer should follow up to ensure that appropriate action has been taken in order to satisfy the contractual and legal requirements.

9.3                   Environmental Complaints

9.3.1             All environmental complaints should be referred to the ET for carrying out complaint investigation procedures. The ET shall prepare a flow chart of the complaint response procedures addressing complaint receiving channels responsible parties/contacts for information, the investigation process, procedures for the implementation of mitigation/ remedial action, guidelines for communication and public relation with the complainant etc. The flow chart should be agreed by all parties and issued to the Contractor, Engineer and IEC for reference.

9.3.2             The ET should undertake the following procedures upon receipt of any complaints:

·      To log the complaints and dates of receipt onto the complaint database to be kept by the Contractor and inform the Engineer and IEC immediately;

·      To investigate with the Engineer and Contractor the complaints to determine their validity, and assess whether the source of the problems is due to the construction works activities with the support of additional monitoring frequency, stations and parameters, if necessary;

·      To identify the mitigation measures if the complaints are valid and due to the construction works of the Project;

 

·      To advise the Contractor if remedial measures are required, and to agree with IEC any additional monitoring frequency, stations and parameters, where necessary, for checking the effectiveness of remedial measures;

·      To review the effectiveness of the Contractor’s responses to the identified remedial measures, and the updated situation;

·      To undertake the additional monitoring and audit in order to verify the situation if necessary, and oversee that the circumstances leading to the complaints would not recur;

·      If the complaint is referred by the EPD, to submit interim report to the EPD on the status of the complaint investigations and follow-up action stipulated above, including the details of the remedial measures and additional monitoring identified or already taken, within the time frame assigned by the EPD; and

·      To record the details of the complaints, results of the investigations, subsequent action 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.

9.3.3             During the complaint investigation, the Contractor and Engineer should coordinate with the ET to provide all the necessary information and assistance for the completion of the investigation. If mitigation measures are identified to be required, the Contractor should promptly implement such measures and the Engineer should ensure that the measures have been carried out properly. A flow chart of the complaint response procedures is shown in Appendix 9-1.
