1 Introduction

1.1 Background

1.1.1 West Kowloon Cultural District (WKCD) is an arts and cultural facilities (ACF) building programme which aims to deliver new performance and visual arts venues, museums, open spaces, education resources, commercial and retail opportunities for the residents of Hong Kong and visitors from overseas. The works include a 2-lane flyover (including approaching roads) across the toll plaza of Western Harbour Tunnel (Austin Road Flyover).

1.1.2 As raised by Members of District Council in the Yau Tsim Mong District Council Meeting in November 2014, traffic leaving WKCD to Austin Road West Roundabout and Nga Cheung Road Flyover would add significant burden on the capacity of these road networks, which are already congested with traffic at the moment. As such, the Revised Austin Road Flyover from WKCD should be proposed to allow access to the section of Lin Cheung Road running in parallel to the West Kowloon Highway (Route 3) aiming to divert traffic from Nga Cheung Road Flyover and Austin Road West Roundabout. The location plan of the Revised Austin Road Flyover is shown in Figure 1.1.

1.1.3 The Revised Austin Road Flyover integrates the proposed exit road with the proposed Flyover. The proposed exit road would connect the service road of West Kowloon Highway (Route 3 ¡V Western Harbour Crossing Tunnel Area). Other than providing connection from WKCD to adjacent local roads, the Revised Flyover provides an additional single road way to alleviate the traffic from the WKCD to the West Kowloon Highway.

1.2 Project Scope and Location

1.2.1 The Project site is situated within part of the WKCD area and across the toll plaza of the Western Harbour Crossing (WHC). The western boundaries of the study area are at the side of the WKCD Waterfront Promenade to the west of the WHC toll plaza, while the eastern boundaries of the study area are at the side of the Austin Road West / Nga Cheung Road roundabout.

1.2.2 The scope of the Revised Austin Road Flyover is to construct and operate a single 2-lane flyover of about 400m connecting the western end of the elevated Austin Road West with the WKCD at the western side of the WHC toll plaza area and mainly comprises:

(i) Construction of a single 2-lane flyover of about 400m long across WHC toll plaza area;

(ii) Construction of a single 2-lane ramp of about 250m long from the western end of the Revised Austin Road Flyover to the WKCD;

(iii) Construction of a single-lane ramp of about 300m long from the western end of the Revised Austin Road Flyover towards the northbound service road of WHC; and

(iv) Modification of at-grade roads within the interface of WKCD road network to connect with the ramp stated in (ii).

1.3 Construction Programme

1.3.1 The Project construction works will be divided into 2 Phases as described below and tentatively commence in 2022 with completion in 2025. The phasing of construction works is illustrated in Figure 1.2, while the tentative construction programme is presented in Appendix A.

¡P Phase 1: Construction of NER (within WKCD Area)

¡P Phase 2: Construction of NER (within WHC Area) and Construction of WHC Flyover (within WHC Area)

1.3.2 The major construction activities for the above 2 Phases will be site clearance / set-up / plant mobilization and underground utilities (UU) protection and diversion works, which are to be followed by construction works including piling works, pile cap and pier / abutment construction, falsework and deck construction, drainage and pavement construction and other miscellaneous works. The tentative construction phase for Phase 1 and Phase 2 will be from March 2022 to December 2024 and from February 2023 to September 2025 respectively.

1.3.3 The Project will be in operation after all construction works are completed, i.e. after September 2025, and no phased operation is planned.

2 Air Quality

2.1 Introduction

2.1.1 Potential air quality impacts arising from the construction and operation phases of the Project on the air sensitive receivers (ASRs) were assessed in the EIA Report. The locations of the representative ASRs are shown in Figure 2.1. No adverse air quality impact from the Project would be anticipated during construction phase. Dust monitoring is proposed to be conducted during construction phase of the Project.

2.1.2 Regular site environmental audit is recommended to be conducted during the entire construction phase of the Project so as to ensure the implementation of the proposed dust mitigation measures and the dust suppression measures stipulated in Air Pollution Control (Construction Dust) Regulation. Implementation schedule of mitigation measures are presented in Appendix C. No adverse air quality impact arising from the Project would be anticipated during the operation phase of the Project. No operational air quality monitoring or audit is therefore considered necessary.

2.1.3 This section presents the requirements, methodology, equipment, monitoring locations, criteria and protocols for the monitoring and audit of air quality impact during the construction phase of the Project.

2.2 Monitoring Parameters

2.2.1 The dusty construction activities of the Project would mainly be related to construction dust from site clearance, minor excavation limited backfilling for column installation and wind erosion of limited exposed area which would generate dust emissions. Therefore, 1-hour Total Suspended Particulates (TSP) is recommended to be monitored and audited at the proposed monitoring locations during construction phase.

2.2.2 The criteria against which ambient air quality monitoring to be assessed are 1-hour TSP limit of 500 µg m^-3_. This level is not to be exceeded at ASRs.

2.2.3 Monitoring and audit of the TSP levels shall be carried out by the ET to ensure that any deteriorating air quality could be readily detected and timely action shall be undertaken to rectify such situation.

2.2.4 1-hour TSP levels should be measured to indicate the impacts of construction dust on air quality. The TSP levels should be measured by following the standard method as set out in High Volume Method for Total Suspended Particulates, Part 50 Chapter 1 Appendix B, Title 40 of the Code of Federal Regulations of the USEPA (hereinafter referred to as ¡§HVS method¡¨). Upon approval of EPD and IEC, an alternative sampling method of using direct reading methods which are capable of producing comparable results as that by the high volume sampling method can be used to indicate short event impacts

2.2.5 All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of sampler, identification and weight of the filter paper, and other special phenomena and work progress of the concerned site, etc., should be recorded down in detail. A sample data sheet is shown in Appendix D.

2.3 Monitoring Equipment

2.3.1 High volume sampler (HVS) in compliance with the following specifications should be used for carrying out the 1-hour TSP monitoring:

• 0.6 - 1.7 m³ per minute (20 - 60 standard cubic feet per minute) adjustable flow range;

2.3.2 The ET shall be responsible for the provision of the monitoring equipment. He shall ensure that sufficient number of HVSs with appropriate calibration kit is available for carrying out the baseline, regular impacts 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, in accordance with requirements stated in the manufacturers operating manual. All the equipment, calibration kit, filter papers, etc., shall be clearly labelled. If direct reading dust meters is proposed to be used, the ET Leader should submit sufficient information to the IEC to prove that the instrument is capable of achieving a comparable result as that the HVS may be used for the 1-hour sampling. The instrument should also be calibrated regularly.

2.3.3 Initial calibration of the dust monitoring equipment shall be conducted upon installation and prior to commissioning at bi-monthly intervals. The transfer standard shall be traceable to the internationally recognized 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.

2.3.4 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 on the data sheet as shown in Appendix D.

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

2.3.6 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 and agreed with the ER and 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 should be divided into 16 sectors of 22.5 degrees each.

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

AM2	ICC	International Commerce Centre
AM3	P46Aa	Parcel 46A - Hong Kong Palace Museum

2.5.2 The status and locations of the air quality sensitive receivers may change after issuing this Manual. In such case, the ET shall propose updated monitoring locations and seek approval from ER and IEC and agreement from EPD on the proposal.

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

(i) at the site boundary or such locations close to the major dust emission source;

(ii) close to the air sensitive receivers as defined in the EIAO-TM;

(iii) proper position/sitting and orientation of the monitoring equipment; and

(iv) take into account the prevailing meteorological conditions.

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

(i) a horizontal platform with appropriate support to secure the samplers against gusty wind shall be provided;

(ii) two samplers shall be placed less than 2 metres apart;

(iii) 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;

(iv) a minimum of 2 metres of separation from walls, parapets and penthouses is required for rooftop samplers;

(v) a minimum of 2 metres of separation from any supporting structure, measured horizontally is required;

(vi) no furnace or incinerator flue is nearby;

(vii) airflow around the sampler is unrestricted;

(viii) the sampler is more than 20 metres from the dripline;

(ix) any wire fence and gate, to protect the sampler, shall not cause any obstruction during monitoring;

(x) permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

(xi) a secured supply of electricity is needed to operate the samplers.

2.6 Baseline Monitoring

2.6.1 Baseline monitoring shall be carried out to determine the ambient 1-hour TSP levels at the monitoring locations prior to the commencement of the Project. During the baseline monitoring, there shall not be any construction or dust generating activities in the vicinity of the monitoring stations. The baseline monitoring will provide data for the determination of the appropriate Action levels with the Limit levels set against statutory or otherwise agreed limits.

2.6.2 Before commencing the baseline monitoring, the ET 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 TSP baseline monitoring should be carried out at all of the designated monitoring locations for at least 14 consecutive days prior to the commissioning of the construction works. 1-hour TSP sampling shall be done at least three times per day at each monitoring station. During the baseline monitoring, there should not be any construction or dust generating activities in the vicinity of the monitoring stations. General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources should also be recorded throughout the baseline monitoring period. A summary of baseline monitoring is presented in Table 2.2.

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 location shall be approved by the ER and agreed with 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 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. The revised baseline levels, in turn, the air quality criteria, shall be agreed with the IEC and EPD.

2.7 Impact Monitoring

2.7.1 The ET shall carry out impact monitoring during construction phase of the Project. For 1-hour TSP monitoring, the sampling frequency of at least three times in every six-days should be undertaken when the highest dust impact occurs. In case of non-compliance with the air criteria, more frequent monitoring, as specified in the Action Plan in the following section, should be conducted. This additional monitoring should be continued until the excessive dust emission or the deterioration in the air quality is rectified. The impact monitoring programme is summarized in Table 2.2.

2.7.2 The monthly schedule of the compliance and impact monitoring programme should be drawn up by the ET one month prior to the commencement of the scheduled construction period. Before commencing the impact monitoring, the ET 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.

Monitoring Period	Duration	Sampling Parameter	Frequency
Baseline Monitoring	Consecutive days of at least 2 weeks before commencement of major construction works	1-hour TSP	3 times per day
Impact Monitoring	Throughout the construction phase	1-hour TSP	3 times in every 6 days

2.8 Event and Action Plan

2.8.1 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 2.3 shows the air quality criteria, namely Action and Limit levels to be used. Should non-compliance of the air quality criteria occur, action in accordance with the Action Plan in Table 2.4 shall be carried out.

Submit proposals for remedial measures to the ER with a copy to the IEC and ET within three working days of notification; 4. Implement the agreed proposals; 5. Revise and resubmit proposals if problem still not under control; and 6. Stop the relevant portion of works as determined by the ER until the exceedance is abated.

2.9 Mitigation Measures

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

2.10 Audit Requirements

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

3 NOISE

3.1 Introduction

3.1.1 Potential noise impacts arising from the construction and operation phases of the Project on the representative noise sensitive receivers were assessed in the EIA Report. The locations of the representative NSRs are shown in Figure 3.1. No construction noise exceedances would be predicted at the representative NSRs during the construction phase of the Project. Nevertheless, construction noise monitoring is recommended during the construction phase to check compliance with the noise criteria.

3.1.2 No adverse noise impact arising from the Project would be anticipated during the operation phase of the Project. No operational noise monitoring or audit is therefore considered necessary.

3.1.3 In this section, the requirements, methodology, equipment, monitoring locations, and protocols for the monitoring and audit of noise impacts during the construction phase of the Project are presented.

3.2 Monitoring Parameters

3.2.1 The construction noise level should be measured in terms of the 30-minute A-weighted equivalent continuous sound pressure level (L_eq). L_{eq (30 min)} should be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays.

3.2.2 Supplementary information for data auditing and statistical results such as L₁₀ and L₉₀ should also be obtained for reference. Sample noise field data sheets are shown in Appendix D of this Manual for reference. The ET Leader may modify the data record sheet for this EM&A programme but the format of which should be agreed by the IEC.

3.3 Monitoring Equipment

3.3.1 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 shall be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.

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

3.3.3 The ET is responsible for the provision of the monitoring equipment. He shall ensure that sufficient noise measuring 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.

3.4 Monitoring Locations

3.4.1 The proposed noise monitoring stations for the construction phase are listed in Table 3.1 and shown in Figure 3.2. The locations of noise monitoring stations and the works activities may change after issuing this Manual. For such occasion, the ET Leader shall propose with justification for changes to monitoring locations or other requirements of the EM&A programme, taking into account the following considerations and seek approval from the IEC and EPD:

(i) locate close to the major site activities which are likely to have noise impacts;

(ii) locate close to the most affected existing NSRs; and

(iii) take into account the possibility of minimizing disturbance to occupants at the NSRs during monitoring.

Table 3.1 Proposed Noise Monitoring Stations for Baseline and Impact Monitoring

Noise Monitoring Station	Noise Assessment Point ID in EIA	Location
NM1	CUL1	The Cullinan I
NM2	CUL2	The Cullinan II
NM3	HT	The Harbourside ¡V Tower 3
NM4	SRT	Sorrento ¡V Tower 1

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

3.5 Baseline Monitoring

3.5.1 Baseline noise monitoring shall be carried out daily in all identified monitoring stations for 2 weeks prior to the commissioning of the construction works. The baseline noise levels of A-weighted levels L_eq, L₁₀ and L₉₀, should be measured for a continuous period of at least 14 consecutive days at a minimum logging interval of 30 minutes for daytime (between 0700 and 1900 hours of normal weekdays) and 15 minutes (as three consecutive Leq, (5 minutes) readings) for evening time (between 1900 and 2300 hours on normal weekdays), general holidays including Sundays (between 0700 and 2300 hours) and night-time (between 2300 and 0700 on all days). A schedule of the baseline monitoring shall be submitted to the IEC for approval before the monitoring starts.

3.5.2 During the baseline monitoring, there shall not be any construction activities in the vicinity of the monitoring stations.

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

3.6 Impact Monitoring

3.6.1 Construction noise monitoring should be carried out at the designated monitoring station when there are Project-related construction activities being undertaken within a radius of 300 m from the monitoring stations. The monitoring frequency should depend on the scale of the construction activities. An initial guide on the monitoring is to obtain one set of 30-minute measurement at each station between 0700 and 1900 hours on normal weekdays at a frequency of once a week when construction activities are underway. A schedule of the impact monitoring shall be submitted to the IEC for approval before the monitoring starts.

3.6.2 If construction works are extended to include works during the hours of 1900 to 0700, applicable permits under NCO shall be obtained by the Contractor. The monitoring requirements and conditions stipulated in the permits have to be followed.

3.6.3 In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Action Plan in Table 3.3 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 The action and limit levels for construction noise are defined in Table 3.2. Should non-compliances of the criteria occur, actions in accordance with the Action Plan in Table 3.3 shall be carried out.

Table 3.2 Action and Limit Levels for Construction Noise

Time Period	Action Level	Limit Level
0700 ¡V 1900 hours on normal weekdays	When one documented complaint is received	75 dB(A)

Note:

[1] If works are to be carried out during restricted hours, the monitoring requirements and the conditions stipulated in the Construction Noise Permit (CNP) issued by the Noise Control Authority have to be followed.

Resubmit proposals if problem still not under control; and 5. Stop the relevant portion of works as determined by the ER until the exceedance is abated

3.8 Mitigation Measures

3.8.1 The construction noise assessment results indicate that, in the absence of any mitigation measures, there would not be exceedances of the construction noise criteria at all NSRs. Nonetheless, good site practice was recommended to minimize the potential noise nuisance during construction phase. The Contractor should be responsible for the implementation of these measures. The implementation schedule for the recommended mitigation measures is presented in Appendix C.

3.9 Audit Requirements

3.9.1 Regular site environmental audit at least once per week during the construction phase of the Project should be conducted to ensure good site practices as listed in Appendix C are implemented properly to further minimize the potential noise nuisance during construction phase of the Project.

4 WATER QUALITY

4.1 Introduction

4.1.1 Potential water quality impacts arising from the construction and operation phases of the Project on the representative water sensitive receivers (WSRs) were identified and assessed in the EIA Report. The locations of the representative WSRs are shown in Figure 4.1. While the project only consists of land-based works, and no adverse water quality impacts would be expected with implementation of the recommended mitigation measures according to the assessment result of the EIA Report, water quality monitoring is considered not necessary. Nonetheless, regular site inspections are recommended during the construction phase to ensure the recommended mitigation measures are properly implemented.

5 WASTE MANAGEMENT Implication

5.1 Introduction

5.1.1 Construction and Demolition (C&D) materials, chemical waste and general refuse from workforce would be generated during the construction phase. It is the Contractor¡¦s responsibility to ensure that all the waste arising from the Project are handled, stored and disposed of in accordance with good waste management practices, relevant legislation and waste management guidelines. Provided that these wastes are handled, transported and disposed of using approved methods and that the recommended good site practices and relevant legislation are strictly followed, adverse environmental impacts would not be expected.

5.1.2 It is expected that no waste will be generated during the operation phase of the Project. As such, it is considered that there should be no adverse environmental impacts. Monitoring and audit programme for the operation phase of the Project would not be required.

5.2 Mitigation Measures

5.2.1 Mitigation measures for waste management recommended in the EIA Report should form the basis of the site Waste Management Plan (WMP), as part of Environmental Management Plan (EMP), to be developed by the Contractor in the construction stage. Appendix C provides the implementation schedule of the recommended mitigation measures during both construction and operational phases.

5.2.2 Waste generated during the construction activities should be audited regularly by the ET to determine if waste is being managed in accordance with approved procedures and the site WMP. The audit should look at all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislations and contract requirements. In addition, the routine site inspections should check the implementation of the recommended good site practices, waste reduction measures, and other waste management mitigation measures.

5.2.3 With the appropriate handling, storage and removal of waste arisings during the construction of the Project as presented in Appendix C, the potential to cause adverse environmental impacts would be minimized. During the site inspections, the ET shall pay special attention to the issues relating to waste management and check whether the Contractor has implemented the recommended good site practices, waste reduction measures and other mitigation measures.

5.3 Audit Requirements

5.3.1 Regular audits and site inspections should be carried out during construction phases by the ER, ET and Contractor to ensure that the recommended good site practices and the recommended mitigation measures listed in Appendix C are properly implemented by the Contractor. The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.

5.3.2 The requirements of the environmental audit programme are set out in Section 8 of this Manual. The audit programme should verify the implementation status and evaluate the effectiveness of the mitigation measures.

6 LAND CONTAMINATION

6.1 Introduction

6.1.1 The land contamination assessment has examined the potential contaminating land uses within the Assessment Area and investigated any potential land contamination impacts arising from the Project.

6.1.2 Based on the site appraisal, adverse land contamination impact arising from Project is not anticipated. No EM&A programme is therefore required.

7 Landscape And Visual Impact

7.1 Introduction

7.1.1 The EIA has recommended landscape and visual mitigation measures to be undertaken during both the construction and operational phases of the Project. The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that any potential conflicts between the proposed landscape measures and any other works of the Project would be resolved as early as practicable without affecting the implementation of the mitigation measures.

7.2 Mitigation Measures

7.2.1 The proposed mitigation measures of landscape and visual impacts are summarized in Appendix C. The landscape and visual mitigation measures proposed should be incorporated in the detailed landscape and engineering design. The construction phase mitigation measures should be adopted from the commencement of construction and should be in place throughout the entire construction period. Mitigation measures for the operational phase should be adopted during the detailed design and be built as part of the construction works so that they are in place on commissioning of the Project.

7.2.2 Any potential conflicts among the proposed mitigation measures, the Project works, and operational requirements should also be identified and resolved at early stage. Any changes to the mitigation measures should be incorporated in the detailed design.

7.3 Audit Requirement

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

7.3.2 In the event of non-compliance, the responsibilities of the relevant parties are detailed in the Event/Action plan provided in Table 7.1.

9.6 Data Keeping

9.6.1 No site-based documents (such as monitoring field records, laboratory analysis records, site inspection forms etc.) are required to be included in the EM&A reporting documents. However, any such documents should be properly maintained by the ET and be ready for inspection upon request. All relevant information should be recorded in electronic format, and the software copy must be available upon request. All document and data should be kept for at least one year after completion of the construction phase of the project.

9.7 Interim Notifications of Environmental Quality Limit Exceedances

9.7.1 With reference to the Event and Action Plan, when the environmental quality performance limits are exceeded and if they are proven to be valid, the ET should immediately notify the IEC, WKCDA and EPD, as appropriate. The notification should be followed up with advice to the IEC, WKCDA and EPD on the results of the investigation, proposed actions and success of the actions taken, with any necessary follow-up proposals.  A sample template for the interim notification is presented in Appendix E.
