Note: [1] The impact monitoring period is determined based on the distance between the stages of development and the monitoring locations. Impact monitoring is recommended when the stages in the vicinity of the monitoring locations are under construction. The stages of the Project will subject to adjustment based on the actual construction programme of the relevant contracts in the Construction Stage.

5.5.2 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 the IEC, and agreement from the EPD on the proposal.

5.5.3 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.

5.5.4 The ET shall agree with the ER in consultation with the IEC on the position of the HVS for the 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. the distance between the sampler and an obstacle, such as buildings, shall be at least twice the height that the obstacle protrudes above the sampler;

iii. a minimum of 2 metres of separation from walls, parapets and penthouses is required for rooftop samplers;

iv. a minimum of 2 metres of separation from any supporting structure, measured horizontally is required;

v. no furnace or incinerator flue is nearby;

vi. airflow around the sampler is unrestricted;

vii. the sampler is more than 20 metres from the dripline;

viii. any wire fence and gate, to protect the sampler, shall not cause any obstruction during monitoring;

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

x. a secured supply of electricity is needed to operate the samplers; and

xi. no two samplers should be placed less than 2 metres apart.

5.5.5 Before construction in each month, the corresponding dust monitoring schedule shall be prepared by the ET based upon the construction schedule provided by the Contractor. The ET shall forward the IEC the impact monitoring programme such that he/she can conduct on-site audits to ensure accuracy of the impact monitoring results.

5.6 Baseline Monitoring

5.6.1 The ET shall carry out the baseline monitoring at all of the designated monitoring locations (Table 5.1) for at least 14 consecutive days prior to the commissioning of major construction works to obtain 1-hour TSP samples. The selected baseline monitoring stations should reflect baseline conditions at the impact monitoring stations. One-hour sampling should also be done at least 3 times per day while the highest dust impact is expected.

5.6.2 During the baseline monitoring, there should not be any major construction or dust generation activities in the vicinity of the monitoring stations. Before commencing baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that, if required, the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

5.6.3 In case the baseline monitoring cannot be carried out at the designated monitoring locations during the baseline monitoring period, the ET 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 agreed with the Engineer and the IEC, and approved by the EPD.

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

5.6.5 Ambient conditions may vary seasonally and shall be reviewed once every three months. If the ET considered that the ambient conditions have changed and a repeat of the baseline monitoring is required to be carried out for obtaining the updated baseline levels, the monitoring should be at times when the Contractor's activities are not generating dust, at least in the proximity of the monitoring stations. Should change in ambient conditions be determined, the baseline levels and, in turn, the air quality criteria, should be revised. The revised baseline levels and air quality criteria should be agreed with the IEC and the EPD.

5.7 Impact Monitoring

5.7.1 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 quality criteria, more frequent monitoring, as specified in the action plan in the following section, should be conducted within the specified timeframe after the result is obtained. 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 5.2.

Table 5.2 Summary of Construction Dust Monitoring Programme

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 every 6 days

6. Noise Impact

6.1 Introduction

6.1.1 In the EIA Report, construction noise monitoring and regular site audit have been recommended to be carried out during construction phase to ensure the construction noise level will comply with the relevant noise criteria.

6.1.2 Road traffic noise levels should also be monitored at representative noise sensitive receivers (NSRs), which are in the vicinity of the recommended direct mitigation measures, upon the population intake of the proposed development. The purpose of the monitoring is to compare the measured noise levels with the predicted noise levels, appropriate conversion corrections shall be applied to allow for the traffic conditions at the time of measurement.

6.1.3 Monitoring of fixed noise sources of the planned SHR SPS and the public transport interchanges (PTIs) during the testing and commissioning stage was also recommended to verify the compliance with the EIAO-TM criteria.

6.2 Noise Monitoring Parameters for Construction Noise

6.2.1 Construction noise level shall be monitored by the ET and shall be measured in terms of the A-weighted equivalent continuous sound pressure level (L_eq). L_eq_(30-min) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. For all other time periods, L_eq_(5-min)shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. A sample data sheet is shown in Appendix 6.1.

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

6.3 Monitoring Equipment for Construction Noise

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

6.3.2 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.

6.3.3 The ET is responsible for the provision, installation, operation, maintenance, dismantling 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.

6.4 Monitoring Locations for Construction Noise

6.4.1 NSRs that are anticipated to have the highest construction noise level when without mitigation measures were selected as monitoring stations. The locations of construction noise monitoring stations are summarised in Table 6.1 and shown in Figure 6.1.

Table 6.1 Proposed Construction Noise Monitoring Locations

ID	NSR ID	Description	Impact Monitoring Period^[^1]

CN6	E16_CN03	Luk Tin House, Yan Tin Estate	Stage 1
CN7	E30_CN01	C.C.C. Mong Wong Far Yok Memorial Primary School	Stage 1, Stage 3 and Stage 4
Note: [1] The impact monitoring period is determined based on the distance between the stages of development and the monitoring locations. Impact monitoring is recommended when the stages in the vicinity of the monitoring locations are under construction. The stages of the Project will subject to adjustment based on the actual construction programme of the relevant contracts in the Construction Stage.

6.4.2 If the status or location of a NSR changes after issuing this manual, the ET shall propose the updated monitoring location and seek approval from the ER and agreement from the IEC and the EPD of the proposal to amend the monitoring location.

6.4.3 When alternative monitoring locations are proposed, the monitoring locations shall be chosen taking account of the following criteria:

a) All locations close to the major site activities that are likely to have noise impacts;

b) Close to the NSRs as defined in the EIAO-TM; and

c) Assurance of minimal disturbance to the occupants during monitoring.

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

6.5 Baseline Monitoring for Construction Noise

6.5.1 In accordance with Section 4.2 of Appendix D2 of Guidelines for Development Projects in Hong Kong published by EPD, Baseline noise monitoring before commencement of construction works is not normally required.

6.6 Impact Monitoring for Construction Noise

6.6.1 Construction noise monitoring should be carried out at the designated monitoring stations (Table 6.1) directly affected by the construction works once every week after the commencement of construction. During construction works, one set of L_eq_(30-min)measurement at each station between 0700 and 1900 hours on normal weekdays shall be taken. If construction works are extended to include works during the period between 1900 and 0700 hours, additional weekly impact monitoring shall be carried out during evening and night-time works. Applicable permits under NCO shall be obtained by the Contractor.

6.6.2 In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Event and Action Plan in Table 6.3, shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be unrelated to the construction activities.

6.7 Action and Limit Levels for Construction Noise

6.7.1 The Action and Limit levels for construction noise are defined in Table 6.2. Should non-compliance of the criteria occur, the ET, the IEC, the ER and the Contractor shall undertake their specified actions in accordance with the Event and Action Plan shown in Table 6.3.

Table 6.2 Action and Limit Levels for Construction Noise

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

Notes:

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

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

6.8 Event and Action Plan for Construction Noise

6.8.1 Should non-compliance of the noise criteria occur, actions in accordance with the event and action plan in Table 6.3 shall be carried out.

6.9 Noise Monitoring Parameters for Operation Road Traffic Noise

6.9.1 The ET should carry out monitoring of road traffic noise after the works under the Project are completed and upon the population intake of the proposed development. The road traffic noise during operation of the Project should be measured in terms of the A-weighted equivalent of L_10(1-hour). During the road traffic noise measurement, traffic count should be undertaken concurrently. Supplementary information for data auditing and statistical results such as L_eq and L₉₀ should also be obtained for reference.

6.10 Monitoring Equipment for Operation Road Traffic Noise and Fixed Plant Noise

6.10.1 The requirement of monitoring equipment for both operational road traffic noise and fixed plant noise could be referred to Section 6.3.

6.11 Monitoring Locations for Operation Road Traffic Noise

6.11.1 Those most affected NSRs identified in the EIA report are selected as the noise monitoring locations in this EM&A Manual. The traffic noise monitoring locations during operation phase are listed in Table 6.4 and shown in Figure 6.2. In addition, noise monitoring shall be carried out for one year following the population intake of the proposed development. The locations for operational noise monitoring shall be defined during detailed design on the basis of the status of the most up-to-date information on proposed developments surrounding the Project.

Note:

[1] “PNB” denotes ID of proposed noise barrier and “LNRS” denotes Low Noise Road Surfacing. The locations of the proposed direct mitigation measures are indicated in Figure 6.3 and 6.4.

6.11.2 The status and locations of NSRs may change after issuing this Manual. In this event, the ET leader shall propose updated monitoring locations and seek approval from the IEC and agreement from the EPD of the proposal.

6.11.3 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 NSRs; 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.

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

6.12 Impact Monitoring for Operational Road Traffic Noise

6.12.1 The ET should prepare and deposit to the EPD, at least 6 months before the operation of the proposed roads under the Project, a monitoring plan for the purpose of overseeing the environmental performance of the development project by comparing the noise impact predictions with the actual impacts. The monitoring plan should contain monitoring locations, monitoring schedules, methodology of noise monitoring including noise measurement procedures, traffic counts and speed checks, and methodology of comparison with the predicted levels. The ET should implement the monitoring plan in accordance with the deposited monitoring plan unless with prior justifications. Monitoring details and results including the comparison between the measured noise levels and the predicted levels should be recorded in a report to be deposited with the EPD within one month of the completion of the monitoring. The report should be certified by the ET leader before it is deposited with the EPD.

6.12.2 Road traffic noise monitoring shall be carried out at all the designated road traffic noise monitoring stations upon the population intake of the proposed development. The following is an initial guide on the road traffic noise monitoring requirements during the operation phase:

· one set of measurements at the morning traffic peak hour on normal days;

· one set of measurements at the evening traffic peak hour on normal days;

· a concurrent census of traffic flow and percentage of heavy vehicles shall be conducted for the Project Road and the existing road network in the vicinity of each measurement point;

· average vehicle speed estimated for Project Road and the existing road network in the vicinity of each measuring point; and

· the two sets of monitoring data shall be obtained within the first year following the population intake of the proposed development.

6.12.3 Measured noise levels shall be compared with the predicted noise levels by applying appropriate conversion corrections to allow for the traffic conditions at the time of measurement.

6.13 Event and Action Plan for Operational Road Traffic Noise

6.13.1 The measured/monitored road traffic 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 cases discrepancies are observed, explanation shall be given to justify the discrepancies.

6.14 Commissioning Test for Operational Fixed Plant Noise

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

6.14.2 The contractor should also carry out a noise commissioning test for all fixed noise sources before operation of the Project, in order to ensure compliance of the noise levels with the EIAO-TM’s stipulated noise standard. The ET should prepare and deposit a commissioning test plan for the fixed plant noise to the EPD, at least six months before the operation of the planned fixed plants. The plan should contain locations, measurement schedules, methodology of noise measurement including noise measurement procedures and data analysis of measured noise level. The commissioning test should be certified by the ET leader and verified by the IEC before submission to the EPD.

6.15 Mitigation Measures

6.15.1 To alleviate the construction noise impact on the affected NSRs, adoption of quieter construction method, use of Quality Powered Mechanical Equipment (QPME), adoption of noise barriers, noise insulating fabrics, or enclosures for particular items of plant and recommendation on workfront management are proposed for the Project during construction phase.

6.15.2 To further alleviate the operation noise impact, vertical noise barriers of various heights were proposed along some sections of the Project roads. A solid concrete boundary wall at the planned housing site near the Welfare Facilities at SHR Site have also been considered. Low noise road surface was proposed for some section of the Project roads and other roads. A fully enclosed pedestrian walkway (~15m long) is proposed at Hing Kwai Street behind the barrier opening for road crossing. Acoustic windows were also proposed to protect the planned residential dwellings. The provision of the solid concrete boundary wall and acoustic windows are subject to further study by the Hong Kong Housing Authority (HKHA). HKHA can further explore alternative options which can achieve corresponding traffic noise reduction during the detailed design stage. The location of the proposed mitigation measures is shown in Figure 6.3 and Figure 6.4 of the EIA Report.

6.15.3 The recommended maximum allowable Sound Power Level of the ventilation fans potentially to be installed at the PTIs should be reviewed with the final design of the PTIs during the detailed design stage. It is recommended that a canopy and hanger wall should be provided at the ingress and egress of the PTIs and solid panels to be erected as necessary next to the vehicle bays to screen the line-of-sight of the PTI from the nearby NSRs. Acoustic windows are proposed at Block 1 of SHR site, as shown in Figure 6.5 to protect the NSRs from adverse rail noise impact.

6.15.4 A Construction Noise Management Plan (CNMP) with reference to Section 8 and Annex 21 of the EIAO-TM as well as this EM&A Manual and the EIA Report should be prepared by the future contractor. In the CNMP, the inventory of noise sources should be verified, and the effectiveness and practicality of all identified measures for mitigating the construction noise impact should be assessed. Mitigation measures proposed in the EIA Report, such as the adoption of quiet construction methods and QPME, should be considered during the design and tendering stage of the Project. The CNMP should confirm the implementation of the mitigation measures, and submitted to EPD for approval six months prior to the commencement of construction. By referring to the measures proposed in the CNMP, the implementation schedule of mitigation measures should also be updated and reflected in the construction program accordingly.

6.15.5 All the recommended mitigation measures and designs are detailed in the implementation schedule in Appendix 4.1.

7. Water Quality Impact

7.1 Introduction

7.1.1 As identified in the EIA report, the key water quality impacts caused by the project would be associated with the land-based construction activities. To ensure no adverse water quality impact to the nearby watercourses due to the discharges from construction activities, water quality monitoring at all major watercourses identified at the vicinity of the construction sites should be carried out before and during the construction phase. It is also recommended that regular weekly site inspections should be undertaken to inspect the construction activities and works areas in order to ensure the mitigation measures recommended in the EIA Report are properly implemented. The water quality monitoring and audit programme should be suitably adjusted according to the phased implementation of the project.

7.1.2 No water quality monitoring and audit programme specific to the operation phase is proposed for the Project.

7.2 Water Quality Parameters

7.2.1 The monitoring shall normally be established by measuring the dissolved oxygen (DO), dissolved oxygen saturation (DO%), temperature, turbidity, salinity, pH and suspended solids (SS) in water bodies at all designated locations as specified in Section 7.5.

7.2.2 The measurements shall be taken at all designated monitoring stations 3 days per week during construction phase. The interval between two sampling surveys shall not be less than 36 hours.

7.2.3 Replicate in-situ measurements and samples collected from each independent sampling event shall be collected to ensure a robust statistically interpretable database. DO, pH value, salinity, temperature and turbidity should be measured in-situ whereas other parameters should be determined by an accredited laboratory.

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

7.3 Monitoring Equipment

Dissolved Oxygen, Dissolved Oxygen Saturation and Temperature Measuring Equipment

7.3.1 The dissolved oxygen (DO) measuring instruments should be portable and weatherproof. The equipment should also complete with cable and sensor, and dc power source. It should be capable of measuring:

· A DO level in the range of 0 – 20 mg/L and 0 – 200% saturation; and

· A temperature of 0 – 45 degree Celsius.

7.3.2 The equipment should have a membrane electrode with automatic temperature compensation complete with a cable.

7.3.3 Should salinity compensation not be built-in to the do equipment, in-situ salinity should be measured to calibrate the do measuring instruments prior to each measurement.

Turbidity Measuring Equipment

7.3.4 The instrument should be a portable and weatherproof turbidity-measuring instrument using a DC power source. It should have a photoelectric sensor capable of measuring turbidity between 0 – 1000 NTU (for example, Hach model 2100P or an approved similar instrument).

Salinity Measuring Equipment

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

pH Measuring Equipment

7.3.6 A portable pH meter capable of measuring a pH range between 0.0 and 14.0 shall be provided under the specified conditions (e.g., Orion Model 250A or an approved similar instrument).

Water Depth Detector

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

Water Sampling Equipment

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

Sample Containers and Storage

7.3.9 Water samples for SS should be stored in high density polythene bottles with no preservative added, packed in ice (cooled to 4°c without being frozen) and keep in dark during both on-site storage and shipment to the testing laboratory. The samples shall be delivered to the laboratory within 24 hours of collection and be analysed as soon as possible after collection.

Calibration of In-Situ Instruments

7.3.10 The pH meter, DO meter and turbidimeter shall be checked and calibrated before use. DO meter and turbidimeter shall be certified by a laboratory accredited under HOKLAS or any other international accreditation scheme, and subsequently re-calibrated at quarterly basis throughout all stages of the water quality monitoring. Responses of sensors and electrodes should be checked with certified standard solutions before each use. Wet bulb calibration for a DO meter shall be carried out before measurement at each monitoring station.

Back-Up Equipment and Vessels

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

7.3.12 The water quality monitoring will involve 10 monitoring stations and measurements should be conducted within the prescribed tidal conditions in order to ensure the measurement / samples are representative. A multi-probe monitoring equipment set integrated with water sampler(s) is highly recommended to improve the monitoring efficiency. The ET shall also consider the use of unattended automatic sampling / monitoring devices at fixed stations where monitoring is required throughout the construction period. The use of such unattended automatic devices, however, shall be subject to the approval of the ER, IEC and EPD.

7.4 Laboratory Measurement / Analysis

7.4.1 At least 3 replicate samples from each independent sampling event are required for the SS measurement that shall be carried out in a HOKLAS or international accredited laboratory. Where water depth is allowed, sampling should be conducted at three water depths which are 1 m below water surface, mid-depth, and 1 m above the river bed. If the sampling water depth is less than 6m, the mid-depth may be omitted. If the water depth is less than 3 m, only the mid-depth sample will be taken. Sufficient water samples shall be collected at the monitoring stations for carrying out the laboratory measurement and analysis. The laboratory determination work shall start within 24 hours after collection of the water samples. The analyses should follow the American Public Health Association (APHA) Standard Methods for the Examination of Water and Wastewater or an equivalent method subject to the approval of EPD. Analytical methods and reporting limits for SS are present in Table 7.1.

Table 7.1 Analytical Methods to be applied to Water Quality Samples

Parameters	Analytical Method	Reporting Limit
Suspended Solid (SS)	APHA 17ed 2540-D *	0.5 mg/L

* APHA - American Public Health Association Standard Methods for the Examination of Water and Wastewater.

7.4.2 The testing of SS should be HOKLAS accredited (or if not, approved by the EPD) and comprehensive quality assurance and control procedures in place to ensure quality and consistency in results.

7.4.3 If in-house or non-standard methods are proposed, details of the method verification may also be required to submit to the EPD. In any circumstance, the sample testing should have comprehensive quality assurance and quality control programmes. The laboratory should prepare to demonstrate the programme to the EPD or his representatives when requested.

7.5 Monitoring Locations

7.5.1 Water quality monitoring will be carried out at 11 locations of the inland water nearby the Project site.

7.5.2 The proposed water quality monitoring locations are shown in Figure 7.1 and listed in Table 7.2. The upstream monitoring stations will act as control stations. Monitoring at the control station is for comparing the water quality from potentially impacted sites with the ambient water quality. The ET shall seek approval from the IEC and the EPD for any alternative monitoring locations. Control stations shall be located within the same body of water as the impact monitoring stations but shall be outside the area of influence of the works and, as far as practicable, not affected by any other works. The gradient monitoring stations are located closer to the worksites and would assist in the identification of sources of any impact at the downstream impact stations.

7.6 Baseline Monitoring

7.6.1 Baseline conditions in the watercourses should be established and agreed with the EPD prior to the commencement of construction works. The purpose of the baseline monitoring is to establish ambient conditions prior to the commencement of the works and to demonstrate the suitability of the proposed monitoring stations. The baseline conditions should normally be established by measuring the water quality parameters specified in Section 7.2.

7.6.2 The baseline monitoring shall be conducted at all designated monitoring stations for at least 4 weeks prior to the commencement of construction works. The proposed water quality monitoring schedule shall be submitted to the EPD by the ET at least 2 weeks before the first day of the monitoring month. The interval between two sets of monitoring shall not be less than 36 hours. The EPD shall also be notified immediately for any changes in schedule.

7.6.3 In general, where the difference in value between the first and second in-situ measurement of DO or turbidity parameters is more than 25% of the value of the first reading, the reading shall be discarded and further readings should be taken.

7.6.4 There should be no construction work in the vicinity of the stations during the baseline monitoring. The baseline data will be used to establish the Action and Limit Levels. The determination of Action and Limit Levels will be discussed in Section 7.9.

9. Ecological Impact

9.1 Introduction

9.1.1 The EIA has recommended mitigation measures to avoid, minimize and compensate identified potential ecological impacts arising from the proposed project. The implementation of these measures shall be checked as part of the environmental monitoring and audit (EM&A) programme during the construction period.

9.2 Ecological Mitigation Measures and Enhancement Planting

9.2.1 Major ecological mitigation measures and enhancement planting recommended to be implemented during the construction phase are summarised below:

a) Ecological enhancement by provision of woodland planting

9.2.2 The enhancement planting shall be monitored throughout the establishment period (i.e. period after the completion of the planting works of the proposed enhancement planting). According to the preliminary woodland compensation plan as shown in Appendix 8.6 of EIA report, 3-years monitoring is proposed and the parameters to be monitored shall include health condition (good/fair/poor/dead) and survival (%) of the planted trees. The frequency of the monitoring is proposed to be bi-monthly during the first year while quarterly for the following years.

9.2.3 The proposed woodland enhancement planting area is indicated in Figure 9.1.

b) Transplanting directly affected individuals of Aquilaria sinensis

9.2.4 According to the ecological impact assessment (Section 8) of the EIA Report, two unavoidably affected individuals of Aquilaria sinensis (including one seedling and one sapling) were recommended to be preserved by transplanting.

9.2.5 In order to confirm and update the condition of the affected Aquilaria sinensis in woodland W3, an update vegetation survey on the species prior to the commencement of the site clearance works is recommended. The update vegetation survey shall include the following:

i) Confirm and update the presence, condition and locations of Aquilaria sinensis;

ii) Identify suitable receptor site(s) for the plants (according to the current proposal stated in Section 8.8 of the EIA Report, suitable unaffected area in woodland W3 is recommended). Receptor site recommended in the EIA Report for the transplanting is indicated in Figure 9.1. Deviation from the proposal shall be fully justified and agreed with AFCD before commencement);

iii) Propose implementation and monitoring programme for the transplanting as well as those temporarily affected individuals.

9.2.6 Qualified ecologist(s) shall be in place to conduct the monitoring recommended in the update vegetation survey report. The monitoring would be conducted after the completion of the transplanting. Monthly monitoring for the first year following transplanting and quarterly for the second year is recommended. The details will be provided in the update vegetation survey report for AFCD’s review and prior agreement.

9.2.7 The findings of the update vegetation survey shall be well presented in the Vegetation Survey Report for AFCD’s review and agreement; while the subsequent routine monitoring findings shall be properly reported in the corresponding Monthly EM&A Report.

c) Ecological Enhancement for the Retained Section of Stream R1f

9.2.8 Apart from the direct avoidance of 208m semi-natural stream R1f to preserve the habitat of the crab species of conservation interest, ecological enhancement is recommended for the retained section onsite (Figure 9.1). Proposed ecological enhancement includes reinstatement of the disturbed stream bank by demolition of all artificial structures and the provision of 6m buffer zone, following by planting of native plants:

i) To demolish artificial bank structures and reinstate natural state of stream bank for reintroduction of riparian vegetation (the demolition works are only undertaken at sections with modified bank structure. Diagram D1 in Appendix 9.1 indicates the extent of the recommended works);

ii) To demolish artificial structures e.g. temporary storage structure/buildings, and paved grounds inside the 6m buffer zone to allow planting; and

iii) To plant the recommended native plant species along the reinstated bank and 6m buffer zone.

9.2.9 In order to minimise the disturbance on the habitat and the crab species, temporary partition along the southern bank of the stream R1f to be reinstated will be provided to, on the one hand, confine the works inside the area enclosed by the temporary partition, and on the other hand, retain the waterflow of R1f to minimise the construction impact on the ecological and hydrological function of the watercourse. Since the demolition of modified banks is small scale works which would not require large works area. The temporary partition is proposed to be set at 1.5m from the southern bank. Demolition works will only be undertaken within the enclosed area.

9.2.10 Since the stream bed of the onsite R1f is basically natural, no further reinstatement works is required.

9.2.11 Recommended native plant species for the riparian planting on the reinstated banks and 6m buffer zone are summarised below:

Species	Proposed Coverage (%)
*Stream Bank (approx. 2m wide within the 6m buffer zone)*
Alternanthera sessilis	25
Commelina diffusa	25
Isachne globosa	10
Ludwigia adscendens	5
Microstegium ciliatum	5
Persicaria hydropiper	5
Rotala rotundifolia	25
*Other Area within 6m buffer (approx. 4m in width)*
Bridelia tomentosa	10
Celtis sinensis	5
Cleistocalyx nervosum	20
Ficus hispida	15
Litsea rotundifolia	15
Mallotus paniculatus	5
Microcos nervosa	10
Schefflera heptaphylla	20

9.2.12 The ecological enhancement works will be an integral part of the detailed design of the proposed development. Relevant works plans and the planting plan shall be reviewed by the responsible qualified ecologist. This qualified ecologist shall be a member of the ET.

9.2.13 A 12-months establishment period shall be provided after the planting works. Monitoring of the plants once a month is recommended. Species planted along the bank and buffer zone shall be checked by a qualified ecologist to ensure correct species are used in accordance with the recommendation in the EIA. Apart from the species identity, monitoring parameters shall include the overall survival rate and general health condition of each species. The monthly monitoring shall be conducted by a qualified ecologist and provide advice whether necessary actions, such as replacement of dead plants, removal of invasive species, etc. are required to ensure the performance of the planting works. The monitoring findings shall be properly reported in the corresponding monthly EM&A report.

d) Translocation of affected crab species of conservation interest Cryptopotamon anacoluthon and Somanniathelphusa zanklon

9.2.14 The enhancement works at R1f will be confined in areas enclosed by temporary partitions about 1.5m from the bank. Majority of the original section of R1f to be retained (about 75% of its area) will be unaffected. During the erection of the temporary partition in the watercourse, most of the individuals of the two crab species Cryptopotamon anacoluthon and Somanniathelphusa zanklon would move away from the works activities to avoid disturbance but, some individuals would be accidentally moved into the demolition works area. Translocation of these affected individuals to the unaffected portion of R1f is therefore recommended.

9.2.15 One locality of Cryptopotamon anacoluthon in R1f (Figure 9.1) is unavoidably affected by the project due to its relevant section of the watercourse is unable to be preserved onsite. In order to minimise the impact on the individuals of this locality, same translocation practice recommended above is also applicable to this section.

9.2.16 A confirmation survey is recommended to be undertaken prior to erection of the temporary partition for the ecological enhancement works for the retained section of stream R1f, which aims to update the condition of the crab localities identified in the EIA stage, and to confirm recommended receptor site(s) (the unaffected section along the retained section of stream R1f is recommended as the preferred receptor site. Other potential receptor sites for consideration are indicated in Figure 9.1); and to advise the translocation methodology according to the survey results and post-translocation monitoring requirements to be agreed with AFCD. The confirmation findings shall be well presented in a Confirmation Survey Report (for Cryptopotamon anacoluthon and Somanniathelphusa zanklon).

9.2.17 It is expected that the translocation practice is to be conducted by the qualified ecologist at the same day of the completion of the erection of the temporary partitions along the bank to be reinstated. The qualified ecologist shall inspect whether individuals of the two crab species are trapped in the enhancement works area defined by the temporary partitions, and carry out translocation immediately according the agreed methodology with AFCD stated in the Confirmation Survey Report (for Cryptopotamon anacoluthon and Somanniathelphusa zanklon).

9.2.18 Collection permit for target species would be applied from AFCD prior to commencement of translocation. Direct capture, hand netting, and baited traps would be applied at the semi-natural stream where the two crab species would be affected by proposed development. Capture would be carried out in wet season when the crabs are more active. At least 3 capture days are proposed, depending on the project programme, site and weather condition, and number of individuals captured. All captured crabs would be temporarily stored in containers with stream water with leaves and over-crowding in the containers should be avoided. They would be translocated to the finalized receptor site(s) within the same day. The ecological enhancement works for the retained section of stream R1f shall only be started when the whole translocation is completed.

9.2.19 A post-translocation monitoring agreed with AFCD through the Confirmation Survey Report (for Cryptopotamon anacoluthon and Somanniathelphusa zanklon) would be carried out by qualified ecologist(s) by the end of wet season after translocation to assess the recapture rate. The monitoring findings shall be properly reported in the corresponding monthly EM&A report.

11. Landscape and Visual Impacts

11.1 Introduction

11.1.1 The EIA has recommended EM&A for landscape and visual mitigation measures to be undertaken during the design, construction and operational stages of the project. The design, implementation and maintenance of landscape mitigation measures is a key aspect of this and should be checked to ensure that they are fully realised and that potential conflicts between the proposed landscape measures and any other project works and operational requirements are resolved at the earliest possible date and without compromise to the intention of the mitigation measures. In addition, implementation of the mitigation measures recommended by the EIA will be monitored through the site audit programme.

11.2 Mitigation Measures

11.2.1 A specialist landscape sub-contractor should be employed by the Contractor for the construction of the landscape works and subsequent maintenance operation during establishment period. A detailed tree survey and topographic survey showing the site conditions should be prepared prior to commencement of works. Detailed tree survey should be prepared by an Arborist accredited by the Hong Kong Institute of Landscape Architects or equivalent employed by the Contractor. For proper implementation of the mitigation measures, a Registered Landscape Architect (RLA) should be employed to check the detailed tree survey and to prepare the Tree Preservation and Removal Proposal (TPRP) in accordance with the EIA Report.

11.2.2 The landscape and visual mitigation measures proposed should be incorporated in the detailed landscape and engineering design. The construction phase mitigation measures should be implemented as early as possible during construction and should be in place throughout the entire construction period. Mitigation measures for the operational phase should be implemented during the detailed design and be built as part of the construction works so that they are in place on commissioning of the Project.

11.2.3 All the recommended mitigation measures and designs are detailed in the implementation schedule in Appendix 4.1.

11.3 Audit Requirement

7.1

7.2

11.3.1 A RLA of the ET should monitor all of the landscape and visual mitigation measures undertaken during the construction phase and throughout establishment period of the operation phase. Site inspection and audit should be undertaken by the RLA at least once every two weeks throughout the construction phase and at least once a month during establishment period. Ad-hoc inspections and audits should also be carried out in case of tree transplantation, adverse weather where significant damage to existing trees is anticipated, and when significant environmental problems are identified. The broad scope of site inspection and audit is detailed below:

11.3.2 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, by a RLA. Particularly audits should be carried out during site clearance when tree felling, and transplantation may occur. For all soft landscaping work, including measures involving trees such as tree transplantation, compensatory planting and woodland restoration, there should be at least a 12-month establishment period (however an extended establishment period and audit mechanism shall be considered where the transplanting of important trees are involved) and maintenance which will commence once soft landscaping in an area has been planted. The broad scope of the audit is detailed below.

· The extent of the agreed works areas should be regularly checked during the construction phase. Any trespass by the contractor outside the limit of the works, including any damage to existing trees and woodland shall be noted and reported to the ER.

· The progress of the engineering works should be regularly reviewed on site to identify the earliest practical opportunities for the landscape works to be undertaken.

· The tree and shrub transplanting and planting operations.

· Topsoil protection and storage operations.

· All existing trees and vegetation within the study area which are not directly affected by the works are retained and protected.

· The methods of protecting existing vegetation proposed by the Contractor are acceptable and enforced.

· All landscaping works are carried out in accordance with the specifications.

· The newly planted trees, shrubs and grassed areas are properly maintained throughout the establishment period.

15. Site Environmental Audit

15.1 Site Inspection

15.1.1 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.

15.1.2 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.

15.1.3 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 situations outside the works area which is likely to be affected, directly or indirectly, by the construction site activities of the Project. The ET shall make reference to the following information in conducting the inspection. During the inspection, the following information should be referred to:

a) EIA Report recommendations on environmental protection and pollution control mitigation measures;

b) works progress and programme;

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

d) contract specifications on environmental protection;

e) relevant environmental protection and pollution control legislations; and

f) previous site inspection results.

15.1.4 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.

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

15.2 Environmental Compliance

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

15.2.2 In order to ensure the works comply with corresponding requirements, all method statements of works should be submitted by the Contractor to the ER for approval and to the ET Leader to ensure sufficient environmental protection and pollution control measures have been included. 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.

15.2.3 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.

15.2.4 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.

15.2.5 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.

15.2.6 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.

15.3 Choice of Construction Method

15.3.1 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 15.1 to the IEC for approval. The IEC should audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts.

15.4 Environment Complaints

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

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

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

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

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

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

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

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

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