1.3.3. The preliminary layouts showing the IWMF facilities at the artificial island near SKC are presented in Figure 1.2.

Construction of the IWMF

1.3.4. The scope of works in construction and operation phase of the Project for the Artificial Island near Shek Kwu Chau is described as below:

1.3.5. Reclamation will be needed to form about 11.8 hectares of land for the IWMF. Due to occasionally rough sea condition in the vicinity of the artificial island near SKC, breakwater will be provided to ensure safe loading and unloading operation at the berth area.

1.3.6. The reclamation will be formed with filling materials supported on the insitu marine deposits with suitable geotechnical ground treatment (such as surcharge loading, installation of vertical band drains, etc.) at a finished ground level of about +5mPD high. Seawalls will be constructed to confine the reclamation area and breakwaters will be provided to protect the water basin. To minimize dredging and filling activities and the associated environmental impacts, vertical cellular structure consisting of circular cells instead of sloping gravity structure is proposed to be adopted for the construction of the seawalls and breakwaters. The cellular breakwater protecting the reclamation area and the water basin would be about +9mPD high for resisting waves with significant heights.

1.3.7. The berth area, which will be extended from the seawall at the northwest side of the reclaimed area, will be formed by a piled deck structure with precast slab. Tubular piles are proposed to form the foundation of the berth. Non-percussive bore piling method would be adopted for the installation of tubular piles.

1.3.8. The construction of the IWMF will mainly include the following stages:-

� Construction of precast concrete cassion surrounding the reclamation area;

� Site filling for reclamation;

� Surcharge loading for reclamation area;

� Construction of breakwater;

� Pilling for berth area;

� Site drainage;

� Foundation (spread footing);

� Civil and building works;

� Mechanical & electrical plant installation;

� Roads, utilities, services and landscaping; and

� Ancillary instrumentation and control works.

Operation of the IWMF

1.3.9. The IWMF will be operated on a 24-hour basis daily, while the reception of MSW would be limited from 8 am to 8 pm.

1.3.10. About 3,000 tpd MSW would be delivered by marine vessels from the existing refuse transfer stations, including Island East Transfer Station, Island West Transfer Station and West Kowloon Transfer Station.

2. AIR QUALITY IMPACT

2.1. Introduction

2.1.1. This section presents the requirements, methodology, equipment, criteria and protocols for the monitoring and audit of air quality impacts during the construction and operation phases of the Project.

2.1.2. The objectives of the air quality monitoring include the following:-

� to identify the extent of construction dust and operational odour impacts;

� to determine the effectiveness of mitigation measures to control dust emission from activities during construction phase and odour control measures during operation phase;

� to audit the compliance of the Contractor with regard to dust control, contract conditions and the relevant dust impact criteria;

� to recommend further mitigation measures if found to be necessary; and

� to comply with action and limit levels for air quality as defined in this Manual.

2.1.3. During the construction phase of the Project, the dust impact would be the major air quality impact. While during operation phase of the Project, stack emissions would be the key environmental issue. Apart from the stack emission, odour emission arising from the operation of the IWMF and its on-site wastewater treatment plant, the waste reception halls, the waste storage area, and the mechanical treatment plant would be another key environmental issue.

2.2. Monitoring during Construction Phase

2.2.1. With the implementation of practicable dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation, adverse construction dust impact at Air Sensitive Receivers (ASRs) is not expected during construction of the Project. In view of the large separation distance of the nearby ASRs from the Project Site, no dust monitoring is considered necessary. Yet, regular site environmental audits during the construction phase of the Project as described in Section 11 of this Manual should be conducted to ensure that the recommended dust suppression measures are implemented properly.

2.2.2. Mitigation measures for dust control have been recommended in the EIA Report and are listed below:-

� Use of regular watering, with complete coverage, to reduce dust emissions from exposed site surfaces and unpaved roads, particularly during dry weather;

� Use of frequent watering for particularly dusty construction areas and areas close to ASRs;

� Side enclosure and covering of any aggregate or dusty material storage piles to reduce emissions. Where this is not practicable owing to frequent usage, watering shall be applied to aggregate fines;

� Open stockpiles shall be avoided or covered. Where possible, prevent placing dusty material storage piles near ASRs;

� Tarpaulin covering of all dusty vehicle loads transported to, from and between site locations;

� Establishment and use of vehicle wheel and body washing facilities at the exit points of the site;

� Provision of wind shield and dust extraction units or similar dust mitigation measures at the loading points, and use of water sprinklers at the loading area where dust generation is likely during the loading process of loose material, particularly in dry seasons / periods;

� Imposition of speed controls for vehicles on unpaved site roads. Ten kilometres per hour is the recommended limit;

� Where possible, routing of vehicles and positioning of construction plant should be at the maximum possible distance from ASRs; and

� Instigation of an environmental auditing program to monitor the construction process in order to enforce controls and modify method of work if dusty conditions arise.

2.2.3. The Contractor shall be responsible for the design and implementation of these measures.

2.3. Monitoring during Operation Phase

2.3.1. Stack Monitoring

2.3.1.1 Monitoring of air quality parameters of concern due to stack emissions has to be conducted during operation phase of the Project in accordance with the requirements similar to those stipulated in the �A Guidance Note on the Best Practicable Means for Incinerators (Municipal Waste Incineration) BPM 12/1�.

2.3.1.3 Necessary monitoring equipment and techniques should be provided and used to demonstrate that the process is properly operated and the emissions can be minimized to meet the air pollution control requirements. The scope, manner and frequency of the monitoring should be sufficient for this purpose and will be determined by EPD. Monitoring results should be recorded in such manner specified by EPD. The record should be retained at the premises for a minimum of two years, or other period specified by EPD, after the date of last entry and be made available for examination as and when required by EPD.

2.3.1.4 On-line monitoring and periodic measurement shall be carried out and the results shall be properly recorded. Evidence should be provided to demonstrate quality assurance procedures are in place to ensure all monitoring results are sufficiently accurate and reliable. Calibration on the monitoring equipment has to be done by means of parallel measurements with the reference methods as agreed by EPD. The requirements of the on-line monitoring and periodic measurement are provided in the following sections.

2.3.2. On-line Monitoring

2.3.2.1 Continuous monitoring of the in-stack exhaust gas and the process shall be carried out. The continuous monitoring data should be transmitted instantaneously to EPD by telemetry system in such manner and format agreed with EPD. The parameters to be continuously monitored are listed below:-

In-stack Exhaust Gas Continuous Monitoring

� nitrogen oxides

� hydrogen chloride

� hydrogen fluoride

� sulphur dioxide

� opacity

� gaseous and vaporous organic substances

� carbon monoxide

� oxygen

� pressure

� temperature

� water vapour content (The continuous measurement of the water vapour content should not be required if the sampled exhaust gas is dried before the emissions are analysed.)

2.3.3. Process Continuous Monitoring

2.3.2.1 Temperature and oxygen content of the gas at the appropriate location(s) in the combustion chamber to demonstrate the compliance of the requirements set out in paragraphs 4.3.1 to 4.3.4 of EPD�s Guidance Note on the Best Practicable Means for Incinerators (Municipal Waste Incineration) BPM 12/1

2.3.2.2 Temperature of the gas at the appropriate location(s) in the chimney to demonstrate that the exit temperature of the exhaust gas from the chimney of the incineration process is not less than 80�C at full load condition

2.3.2.3 Other essential operating parameter(s) which may affect the performance of air pollution control measures

2.3.4. Periodic Measurement

2.3.4.1 To confirm that the levels of dioxin and heavy metals are being adequately controlled, periodic measurements shall be made.

2.3.4.2 The sampling frequency will be determined by EPD. All measurement results should be recorded, processed and presented in a summary report as agreed by EPD. The report should be submitted to EPD without delay after the source sampling(s) as required is/are completed.

2.3.5. Odour Monitoring

2.3.5.1 To determine the effectiveness of the proposed odour mitigation measures and to ensure the odour impacts arising from the operation of the IWMF and the waste reception halls, the waste storage area and mechanical treatment plant meeting the air pollution control requirements, odour monitoring shall be conducted. Odour monitoring involves odour patrols conducted by an odour patrol team. The odour patrol team will patrol and sniff along an odour patrol route along the IWMF site boundary. The implementation of the odour monitoring shall be subject to the prevailing weather forecast condition and no odour monitoring should be carried out during rainy day.

2.3.5.2 The odour patrol team shall be comprised of at least two independent trained personnel / competent persons, who should pass a set of screening tests and fulfil the following requirements:-

� have their individual odour threshold of n-butanol in nitrogen gas in the range of 20 to 80 ppb/v required by the European Standard Method (EN 13725);

� be at least 16 years of age and willing and able to follow instructions;

� be free from any respiratory illnesses;

� not allowed to smoke, eat, drink (except water) or use chewing gum or sweets 30 min before and during odour patrol;

� take great care not to cause any interference with their own perception or that of others by lack of personal hygiene or the use of perfumes, deodorants, body lotions or cosmetics; and

� not communicate with each other about the results of their choices.

2.3.5.3 The independent trained personnel / competent persons should use their noses (olfactory sensors) to sniff odours at different locations. The main odour emission sources and the areas to be affected by the odour nuisance shall be identified. During the patrol, the sequence should generally start from less odorous locations to stronger odorous locations.

2.3.5.4 The perceived odour intensity is divided into 5 levels. Table 2.2 describes the odour intensity for different levels.

Table 2.2 Odour Intensity Level

Level	Odour Intensity
0	Not detected. No odour perceived or an odour so weak that it cannot be easily characterised or described
1	Slight identifiable odour, and slight chance to have odour nuisance
2	Moderate identifiable odour, and moderate chance to have odour nuisance
3	Strong identifiable, likely to have odour nuisance
4	Extreme severe odour, and unacceptable odour level

2.3.5.5 The independent trained personnel / competent person shall record the findings including date and time, weather condition (e.g. sunny, fine, cloudy, and rainy), odour intensity, odour nature and possible odour sources, local wind speed, and wind direction at each location. In addition, some relevant meteorological data such as daily average temperature, and daily average humidity on the day of odour patrol shall be obtained from the nearest Hong Kong Observatory station for reference.

2.3.5.6 Odour patrols will be conducted in summer (i.e. from July to September). In the first 2 operational years of the IWMF, monthly odour patrols shall be conducted. Odour patrols shall be carried out during daytime and evening / night time when the IWMF and its waste reception halls, the waste storage area and the mechanical treatment plant are operated under normal operating condition.

2.3.5.7 The need to continue the odour patrol after the end of the 2-year monitoring period would depend on the monitoring results and should be agreed with EPD. If the level of odour intensity at any sniffing location is higher than 1 due to potential odour emission from the IWMF and its waste reception halls, the waste storage area and the mechanical treatment plant in two consecutive months, the odour patrol programme would be extended until the level of odour intensity (that is determined to be due to potential odour emission from the IWMF or the associated facilities) at all the sniffing locations have dropped to 0 in three consecutive months.

2.3.5.8 Table 2.3 shows the action level and limit level to be used for odour patrol. Should any exceedance of the action and limit levels occurs, actions in accordance with the event and action plan in Table 2.4 should be carried out.

Table 2.3 Action and Limit Levels for Odour Nuisance

3. NOISE IMPACT

3.1. Introduction

3.1.1. In this section, the requirements, methodology, equipment, monitoring locations, criteria and protocols for the monitoring and audit of noise impacts during the construction phase of the Project are presented. The proposed mitigation measures during construction and operation phases of the Project are also described in this section.

3.1.2. Construction noise impacts from this Project are predicted at the identified Noise Sensitive Receivers (NSRs). Noise mitigation measures would be required to reduce noise levels to the stipulated standard. A noise monitoring programme shall be undertaken to ensure such mitigation measures would be implemented properly.

3.2. Noise Parameters

3.2.1. Construction Phase

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

3.2.1.2 Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference. A sample data record sheet based on the one presented in the EM&A Guidelines for Development Projects in Hong Kong is shown in Appendix 3.1. The ET Leader may modify the data record sheet for this EM&A programme, of which the format should be agreed by the SOR and the IEC.

Monitoring Equipment

3.2.1.3 As referred 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 levels from before and after the noise measurement agree to within 1.0 dB

3.2.1.4 Noise measurements shall not be made in fog, rain, wind with a steady speed exceeding 5m/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.

3.2.1.5 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.

3.2.1.6 The locations of construction noise monitoring stations are summarized in Table 3.1 and shown in Figure 3.1. These locations represent the worst affected sensitive receivers during construction phase of the Project.

Table 3.1 The Locations of Construction Noise Monitoring Station

Station	NSR ID in EIA Report	Noise Monitoring Location
M1	N_S1	Shek Kwu Chau Treatment & Rehabilitation Centre Hostel 1
M2	N_S2	Shek Kwu Chau Treatment & Rehabilitation Centre Hostel 2
M3	N_S3	Shek Kwu Chau Treatment & Rehabilitation Centre Hostel 3

3.2.1.7 The status and locations of noise sensitive receivers may change after issuing this Manual. If such case exists, the ET Leader shall propose updated monitoring locations and seek approval from EPD and agreement from the SOR and the IEC before baseline monitoring commences.

3.2.1.8 When alternative monitoring locations are proposed, the monitoring locations shall be chosen based on the following criteria:

� Monitoring at sensitive receivers close to the major site activities which are likely to have noise impacts;

� Monitoring at the noise sensitive receivers as defined in the Technical Memorandum; and

� Assurance of minimal disturbance to the occupants during monitoring.

3.2.1.9 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. 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. Baseline Monitoring

3.3.1. Construction Phase

3.3.1.1 The ET shall carry out baseline noise monitoring prior to the commencement of the construction works. The baseline monitoring shall be carried out daily for a period of at least two weeks. Before commencing the baseline monitoring, the ET shall develop and submit to the IEC the baseline monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

3.3.1.2 There shall not be any construction activities in the vicinity of the stations during the baseline monitoring.

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

3.4. Impact Monitoring

3.4.1. Construction Phase

3.4.1.1 Noise monitoring shall be carried out at all the designated monitoring stations. 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 weekly basis when noise generating activities are underway:

� One set of measurements between 0700 and 1900 hours on normal weekdays.

3.4.1.2 If construction works are extended to include works during the hours of 1900 � 0700 as well as public holidays and Sundays, additional weekly impact monitoring shall be carried out during respective restricted hours periods. Applicable permits under NCO shall be obtained by the Contractor.

3.4.1.3 If a school exists near the construction activity, noise monitoring shall be carried out at the monitoring stations for the schools during the school examination periods. The ET Leader shall liaise with the school�s personnel and the Examination Authority to ascertain the exact dates and times of all examination periods during the course of the contract.

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

3.5. Event and Action Plan

3.5.1. Construction Phase

3.5.1.1 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 Event and Action Plan in Table 3.3 shall be implemented.

Table 3.2 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 (CNP) issued by the Noise Control Authority have to be followed.

3.6. Mitigation Measure

3.6.1. Construction Phase

3.6.1.1 To alleviate the construction noise impact on the affected NSRs, movable noise barriers and acoustic mats are proposed to be provided for particular items of plant and construction works. It is anticipated that a movable noise barrier with a cantilevered upper portion located within 5m from any static or mobile plant can provide 5 dB(A) noise reduction for mobile plant and 10 dB(A) noise reduction for static plant. The barrier material shall have a surface mass of not less than 14 kg/m2 on skid footing with 25 mm thick internal sound absorptive lining to achieve the maximum screening effect.

3.6.1.2 In addition, the good site practices listed below shall be adopted by all the Contractors to further ameliorate the noise impacts.

� Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction program.

� Silencers or mufflers on construction equipment should be utilised and should be properly maintained during the construction program.

� Mobile plant, if any, should be sited as far away from NSRs as possible.

� Machines and plant (such as trucks) that may be in intermittent use should be shut down between works periods or should be throttled down to a minimum.

� Plant known to emit noise strongly in one direction should, wherever possible, be orientated so that the noise is directed away from the nearby NSRs.

� Material stockpiles and other structures should be effectively utilised, wherever practicable, in screening noise from on-site construction activities.

3.6.1.3 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 to identify further mitigation measures. They shall be proposed to SOR for approval, and the contractor shall then implement these additional mitigation measures.

3.6.2. Operation Phase

3.6.2.1 The Contractor should carry out a noise commissioning test for all fixed noise sources before operation of the Project, in order to ensure compliance of the operational airborne noise levels with the TM�s stipulated noise standard.

Table 3.3 Event and Action Plan for Construction Noise

4. WATER QUALITY IMPACT

4.1. Introduction

4.1.1. This section describes the requirements for the monitoring and audit of water quality impacts from the Project.

4.1.2 The water quality assessment undertaken in the EIA Study has identified that suspended solids would be the most critical water quality parameter during the construction stage. Marine water quality monitoring for suspended solids / turbidity and dissolved oxygen is therefore recommended to be carried out at the nearby water sensitive receivers (WSRs). The monitoring should include baseline and impact monitoring. The impact monitoring should be carried out during the proposed reclamation and breakwater construction. Monitoring programme to be implemented for protection of the coral communities are provided in Section 6.

4.1.3 Regular site inspections were recommended to be undertaken to inspect the construction activities and works areas and also the status on the implementation of the recommended mitigation measures. Discharges of drainage water from the construction works areas would be required to comply with the terms and conditions of a discharge licence, issued by EPD, under the Water Pollution Control Ordinance (WPCO). It may be a stipulation of the WPCO licence to require the Contractor to monitor the quality / quantity of the discharge to show compliance with the conditions of the licence. Such monitoring would not form part of the EM&A programme.

4.1.4 As measure to control the dispersion of filling material from the reclamation area, a silt curtain system would be applied at the marine access opening during the reclamation work. A pilot test should be carried out at the early stage of reclamation to verify the silt-removal efficiency of the silt curtain at marine access opening.

4.1.5 During the operation phase of the Project, all generated wastewater will be discharged into an on-site wastewater treatment plant. The treated effluent from the wastewater treatment plant will be reused for washdown and landscape irrigation in the IWMF site. A �net zero discharge� scheme will be adopted during the operation of the IWMF. Saline water would be discharged from the proposed desalination plant. Monitoring of the change in salinity would be required during the commissioning period of the IWMF.

4.2. Water Quality Parameters

4.2.1 Dissolved oxygen (DO), salinity, turbidity and suspended solids (SS) levels shall be monitored at designated marine water quality monitoring stations before, during and after the marine construction works. The levels of DO, pH, salinity, temperature and turbidity should be measured in situ whereas SS should be determined by laboratory.

4.3. Monitoring Locations

4.3.1 The proposed water quality monitoring stations for construction phase impact assessment are shown in Table 4.1 and Figure 4.1. The status and locations of water sensitive receivers and the marine activities may change after issuing this Manual. If such case exists, the ET Leader shall propose updated monitoring locations and seek approval from the IEC and EPD.

4.3.2 Marine water quality monitoring stations have been proposed at different water quality sensitive receivers to monitor the water quality impact due to the proposed marine works under this Project. Monitoring stations B1 to B4 would be located at 4 beaches respectively at the southern shore of Lantau Island. Monitoring station H1 is located at the horseshoe crab habitat at northern SKC, while CR1 and CR2 are located at the coral communities at southwestern shore of SKC. Monitoring station F1 is located at the Cheung Sha Wan Fish Culture Zone while monitoring station M1 is located at Tung Wan at Cheung Chau. Water quality monitoring at the northern landing site, midway and southern landing site of the proposed submarine cable is proposed at monitoring stations S1, S2 and S3 for monitoring the SS impact due to the laying of submarine cable. Control stations C1 and C2 have been proposed at far field location for comparison. Under the further FEP-01/429/2012/A, the construction works of submarine cable has been surrendered on 17 January 2020. Therefore, no monitoring will be carried out at monitoring stations S1-S3. As existing monitoring locations C1 and C2 are situated at fairway and F1 is located inside Cheung Sha Wan fish culture zone, marine safety concern and concerns from other stakeholders have been raisen. In order to clear up stakeholders� worries, it is thus proposed to relocate C1, C2 and F1 water monitoring location to new locations named as C1A, C2A and F1A as shown in Table 4.1 and Figure 4.2. Those new proposed locations C1A are equivlant to the orginal monitoring stations C1, C2 and F1 respectively, furthermore, those updated locations are verified by IEC and approved by EPD accordingly.

Note: * Under the further FEP-01/429/2012/A, the construction works of submarine cable has been surrendered on 17 January 2020. Therefore, no monitoring will be carried out at monitoring stations S1-S3.

# The monitoring stations were relocated from the organial locations to address stakeholder concerns.

4.3.3 The proposed water quality monitoring stations for operational phase impact assessment are shown in Table 4.2 and Figure 4.2. The monitoring stations proposed in this section are indicative only and may be subjected to further review before commencement of the water quality monitoring works. The locations of brine water outfall may change after issuing this Manual. If such case exists, the ET Leader shall propose updated monitoring locations and seek approval from the IEC and EPD.

4.3.4 Marine water quality monitoring stations have been proposed near the saline water outfall to monitor the water quality impact due to the proposed saline water discharge. Monitoring stations Z1 to Z3 would be located near the eastern, southern and western edge of the zone of initial mixing based on the results of modelling work conducted under this EIA. Control stations C3 and C4 have been proposed at far field location for comparison.

Table 4.2 Proposed Marine Water Quality Stations for Baseline and Impact Monitoring during Operational Phase

C3	Control Station	817065	805416
C4	Control Station	816484	805416

Note: **ZID refers to �Zone of Initial Mixing�

4.3.5 Sampling for baseline and impact monitoring shall be taken at three water depths, namely, 1m below water surface, mid-depth and 1m above seabed, except at where the water depth is less than 6m, in which case the mid-depth station may be omitted. Shall the water depth be less than 3m, only the mid-depth station will be monitored.

4.4. Baseline Monitoring

4.4.1 Construction Phase

4.4.1.1 Baseline conditions for marine water quality should be established and agreed with EPD prior to the commencement of marine works. The purpose of the baseline monitoring is to establish ambient conditions prior to the commencement of the marine works and to demonstrate the suitability of the proposed monitoring stations.

4.4.1.2 The baseline conditions should be established by measuring suspended solids (SS), salinity, turbidity and dissolved oxygen (DO) levels at the selected monitoring stations as shown in Table 4.3. The baseline monitoring schedule should be submitted to EPD at least 4 weeks before commencement of monitoring for agreement. EPD should also be notified immediately for any changes in schedule.

4.4.1.3 The measurements should be taken at all designated monitoring stations, 3 days per week, at mid-flood and mid-ebb tides, for at least 4 weeks prior to the commencement of marine works. There should not be any marine construction activities in the vicinity of the stations during the baseline monitoring. The interval between 2 sets of monitoring should not be less than 36 hours. Duplicate in-situ measurements and water sampling should be carried out in each sampling event.

4.4.1.4 To study the potential variations in the water quality within a year due to natural fluctuations, baseline monitoring shall be conducted for both dry season (October � March) and wet season (April � September).

4.4.1.5 The baseline monitoring report should be submitted to EPD at least 4 weeks before the commencement of the marine works for agreement. The baseline monitoring report should be certified by the ET Leader and verified by IEC before submission to EPD.

4.4.2 Operational Phase

4.4.2.1 Baseline conditions for marine water quality should be established and agreed with EPD prior to the commission of the brine water discharge. The purpose of the baseline monitoring is to establish ambient conditions prior to the commission of the brine water discharge.

4.4.2.2 The baseline conditions should be established by measuring salinity at the selected monitoring stations as shown in Table 4.4. The baseline monitoring schedule should be submitted to EPD at least 4 weeks before commencement of monitoring for agreement. EPD should also be notified immediately for any changes in schedule.

4.4.2.3 The measurements should be taken at all designated monitoring stations, 3 days per week, at mid-flood and mid-ebb tides, for at least 4 weeks prior to the commission of the brine water discharge. There should not be any marine construction activities in the vicinity of the stations during the baseline monitoring. The interval between 2 sets of monitoring should not be less than 36 hours. Duplicate in-situ measurements should be carried out in each sampling event.

4.4.2.4 The baseline monitoring report should be submitted to EPD at least 4 weeks before the commission of the brine water discharge for agreement. The baseline monitoring report should be certified by the IEC before submission to EPD.

4.5 Impact Monitoring

4.5.1 Construction Phase

4.5.1.1 During the period of marine construction, monitoring should be undertaken three days per week, at mid-flood and mid-ebb tides, with sampling / measurement at the designated monitoring stations as shown in Table 4.1. Upon completion of the marine works, the monitoring exercise at the designated monitoring locations should be continued for four weeks in the same manner as the baseline monitoring.

4.5.1.2 The interval between two sets of monitoring should not be less than 36 hours except where there are exceedances of Action and/or Limit Levels, in which case the monitoring frequency will be increased. Table 4.3 shows the proposed monitoring frequency and water quality parameters. Duplicate in-situ measurements and water sampling should be carried out in each sampling event. The monitoring probes should be retrieved out of water after the first measurement and then redeployed for the second measurement. Where the difference in value between the first and second readings of DO or turbidity is more than 25% of the value of the first reading, the reading should be discarded and further readings should be taken.

4.5.1.3 The proposed water quality monitoring schedule should be submitted to EPD at least 1 week before the first day of the monitoring month. EPD should also be notified immediately for any changes in schedule. If the monitoring data collected at the designated stations indicate that the Action or Limit Levels as shown in Table 4.6 are exceeded, appropriate actions should be taken in accordance with the Event and Action Plan in Table 4.7.

EPD should also be notified immediately for any changes in schedule. If the monitoring data collected at the designated stations indicate that the Action or Limit Levels as shown in Table 4.6 are exceeded, appropriate actions should be taken in accordance with the Event and Action Plan in Table 4.8.

4.6 Efficiency of Silt Curtain at Marine Access Opening

4.6.1 The ET shall be responsible for conducting tests to confirm that the silt curtain systems to be adopted at marine access opening for reclamation filling work would achieve the silt removal efficiency stated in the EIA Report.

4.6.2 A method statement shall be submitted by the ET Leader to seek approval from the IEC and EPD.

4.6.3 During the initial period of filling works for reclamation at the SKC site, the silt-removal efficiency of the silt-curtains shall be verified by examining the results of water quality monitoring points. The water quality monitoring points to be selected for the pilot test shall be those close to the marine access opening for the reclamation filling works. The details for the pilot study shall be agreed by EPD.

4.6.4 Pilot tests should be carried out during the early stage of reclamation to confirm whether the silt removal efficiency of the silt curtain systems at marine access opening can achieve at least 80% silt removal efficiency for reclamation filling. The pilot test shall include basic measurements such as turbidity and suspended solids as well as current speed and direction.

4.6.5 Regardless of the measured efficiency of the silt curtain system, the event and action plan shall only be based on the monitoring results at the designed monitoring stations.

4.7 Site Audits

4.7.1 Implementation of regular site audits is to ensure that the recommended mitigation measures are to be properly undertaken during proposed construction works. It can also provide an effective control of any malpractices and therefore achieve continual improvement of environmental performance on site.

4.7.2 Site audits shall be carried out by the ET and shall be based on the mitigation measures for water pollution control recommended in the implementation schedule as presented in Appendix 11.1. In the event that the recommended mitigation measures are not fully or properly implemented, deficiency shall be recorded and reported to the site management. Suitable actions are to be carried out to:

� investigate the problems and the causes;

� issue action notes to the Contractor who is responsible for the works;

� implement remedial and corrective actions immediately;

� re-inspect the site conditions upon completion of the remedial and corrective actions; and

� record the event and discuss with the Contractor for preventive actions.

4.7.3 Daily site audit including full-time on-site monitoring by the ET is required during the dredging for anti-scouring protection layer for checking the compliance with the permitted maximum daily dredging rate and its respective distance from the nearest non-translocatable coral community by the dredging contractor as specified in S.2.18 of the Further Environmental Permit (no.:FEP-01/429/2012/A).

4.8 Field Log

4.8.1 Other relevant data should also be recorded, including monitoring location / position, time, water depth, sampling depth, pH, salinity, DO saturation, water temperature, tidal stages, weather conditions and any special phenomena or work underway nearby.

4.8.2 A sample data record sheet is shown in Appendix 4.1 for reference.

4.9 Monitoring Equipment

Dissolved Oxygen and Temperature Measuring Equipment

4.9.1 The instrument should be a portable and weatherproof DO measuring instrument complete with cable and sensor, and use a DC power source. The equipment should be capable of measuring:

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

� Temperature of 0 ‑ 45 degree Celsius.

Turbidity Measurement Instrument

4.9.2 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).

Standard buffer solutions of at least pH 7 and pH 10 should be used for calibration of the instrument before and after use.

Sampler

4.9.4 A water sampler is required. 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).

Water Depth Detector

4.9.5 A portable, battery-operated echo sounder should be used for the determination of water depth at each designated monitoring station. This unit 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.

Salinity

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

Sample Containers and Storage

4.9.7 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 delivered to the laboratory and analysed as soon as possible after collection. Sufficient volume of samples should be collected to achieve the detection limit stated in Section 4.10.

Monitoring Position Equipment

4.9.8 A hand-held or boat-fixed type digital Differential Global Positioning System (DGPS) with way point bearing indication and Radio Technical Commission for maritime (RTCM) Type 16 error message �screen pop-up� facilities (for real-time auto-display of error messages and DGPS corrections from the Hong Kong Hydrographic Office), or other equipment instruments of similar accuracy, should be provided and used to ensure that the water sampling locations are correct during the water quality monitoring work.

Calibration of In-Situ Instruments

4.9.9 The DO meter and turbidimeter should be checked and calibrated before use. DO meter and turbidimeter should be certified by a laboratory accredited under HOKLAS or any other international accreditation scheme, and subsequently re-calibrated at three monthly intervals 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 should be carried out before and after all measurements on each monitoring day which is considered adequate for the type of DO meter employed.

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

4.10 Laboratory Measurement / Analysis

4.10.1 Analysis of suspended solids (SS) should be carried out in a HOKLAS or other international accredited laboratory. Sufficient water samples should be collected at the monitoring stations for carrying out the laboratory determinations. The determination work should 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. The suggested testing method and lowest detection limit are provided in Table 4.5.

Table 4.5 Analytical Methods to be Applied to Marine Water Quality Samples

Determinant	Standard Method	Detection Limit
Suspended Solids (mg/L)	APHA 2540D*	1 mg/L

Note: * APHA American Public Health Association Standard Methods for the Examination of Water and Wastewater

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

4.10.3 Detailed testing methods, pre-treatment procedures, instruments use, Quality Assurance / Quality Control (QA/QC) details (such as blank, number of duplicate samples per batch, etc.), detection limit and accuracy shall be submitted to EPD for approval prior to the commencement of monitoring programme. EPD may also request the laboratory to carry out analysis of known standards provided by EPD for quality assurance. The QA/QC shall be in accordance with the requirements of HOKLAS or international accredited scheme. The QA/QC results shall be reported. The testing methods and related proposal should be checked and certified by IEC before submission to EPD for approval.

4.10.4 Additional duplicate samples may be required by EPD for inter laboratory calibration. Remaining samples after analysis should be kept by the laboratory for 3 months in case repeat analysis is required. If in-house or non-standard methods are proposed, details of the method verification may also be required by EPD. In any circumstance, the sample testing should have comprehensive quality assurance and quality control programmes. The laboratory should prepare to demonstrate the programmes to EPD or EPD�s representatives when requested.

4.11 Event and Action Plan

4.11.1 The water quality assessment criteria, namely Action and Limit levels are shown in Table 4.7. If the monitoring results of the water quality parameters at any designated monitoring stations indicate that the water quality assessment criteria are exceeded during the construction phase, the actions in accordance with the Event and Action Plan in Table 4.7 should be carried out.

4.11.2 The ET Leader should assess the potential impacts on the water sensitive receivers based on the monitoring data. The performance of the environmental management system (i.e. of the overall EM&A programme) should be reviewed by the ET Leader on a quarterly basis. The findings of this review should be included in the quarterly EM&A summary reports, together with any recommendations to improve the performance of the EM&A programme.

4.11.3 The ET Leader should keep track on the elevation in salinity at the monitoring stations during the commission stage of the desalination plant to ensure the saline water discharge would not result in adverse water quality impact at the nearby water sensitive receivers.

Table 4.6 Action and Limit Levels for Marine Water Quality

Parameters	Action	Limit
Construction Phase Impact Monitoring
DO in mg/L	� 5 %-ile of baseline data	� 4 mg/L
SS in mg/L	� 95 %-ile of baseline data or 120% of control station�s SS at the same tide of the same day of measurement whichever it is higher.	� 99 %-ile of baseline or 130% of control station's SS at the same tide of the same day of measurement whichever it is higher.
Turbidity in NTU	� 95 %-ile of baseline data or 120% of control station�s turbidity at the same tide of the same day of measurement whichever it is higher.	� 99 %-ile of baseline or 130% of control station's turbidity at the same tide of the same day of measurement whichever it is higher.
Operational Phase Impact Monitoring
Salinity in ppm	� 95 %-ile of baseline data or 105% of control station�s salinity at the same tide of the same day of measurement whichever it is higer.	� 99 %-ile of baseline data or 109% of control station�s salinity at the same tide of the same day of measurement whichever it is higher.

Note:

1. For DO, non-compliance of the water quality limits occurs when monitoring result is lower than the limits.

2. For SS and turbidity, non-compliance of the water quality limits occurs when monitoring result is higher than the limits.

4.11.4 If monitoring results indicate that the construction works have caused an adverse impact on water quality at the water sensitive receivers, an additional mitigation measures should be recommended to rectify the non-compliance or the construction programme / design should be carefully reviewed.

4.11.5 If monitoring results indicate that the concentrated saline discharge during the operation phase has caused a significant elevation in salinity beyond the edge of zone of initial mixing, actions should be taken as stated in Table 4.8.

4.13 Marine Water Quality Monitoring for Deep Cement Mixing Works

4.13.1 Monitoring and audit on water aspect for deep cement mixing (DCM) sould be carried out before, during and after the DCM field trial and any full-scale DCM works. In-situ measurements of turbidity, water temperature, dissolved oxygen and pH as well as water sampling (for subsequent laboratory analysis of SS and alkalinity) should be taken at both upstream and downstream of any DCM works. Current velocity or direction should also be taken near the proposed DCM works to determine the appropriate upstream and downstream monitoring locations. If the measurements and water sampling results indicate that the DCM works have caused significant changes in water conditions at the downstream station, appropriate actions should be taken to stop the works and mitigation measures such as slowing down the DCM process, or rescheduling of works would be implemented to reduce the impacts. In-situ measurements and water sampling on water aspect for the concerned parameters should be collected at selected WSRs before, during and after the DCM works to confirm the impact on water aspect. Before the commencement of any DCM works for the Project, a detailed plan on DCM will be submitted to the EPD for approval. The detailed plan on DCM will include the work programme, layout, monitoring programme on water aspect (including monitoring parameters, locations, frequency, duration and event & action plan) of the DCM works, and mitigation measures to be taken to avoid adverse impacts on water aspect.

5 WASTE MANAGEMENT IMPLICATIONS

5.1 Introduction

5.1.1 Waste management would be the Contractor�s responsibility to ensure that all wastes produced during the construction of the Project are handled, stored and disposed of in accordance with the recommended good waste management practices and EPD�s regulations and requirements.

5.1.2 Waste materials generated from construction activities, such as dredged marine sediment, construction and demolition (C&D) materials, chemical waste and general refuse, are recommended to be audited at regular intervals (at least once per week as part of the regular site inspections described in this EM&A Manual) to ensure that proper storage, transportation and disposal practices are being implemented. The Contractor would be responsible for the implementation of the mitigation measures to minimize waste or redress problems arising from the waste materials.

5.1.3 Besides, during operation phase of the Project, the EIA Report recommended that the incineration by-products should be tested in accordance with the requirements of the proposed Incineration Residue Pollution Control Limits as recommended in the EIA Report prior to disposal to landfill. A number of the land contamination preventive measures are also recommended in the EIA Report for the operation of the Project.

5.1.4 Biogas generation (under the scenario that dredging is not required for the reclamation of the artificial island near SKC) is assessed in the EIA study. Gas protection measures are recommended to be incorporated in the building design. These recommended mitigation measures to prevent the ingress and/or accumulation of any methane gas emissions to potentially dangerous concentrations are described in Section 6 of the EIA Study. Precautionary measures to be taken prior to entry into any below ground services or confined space within the reclamation site are also recommended. The EIA Report recommended that gas monitoring be undertaken in the immediate post-reclamation period to measure methane concentrations in the fill and to determine actual rates of methane gas emissions. The recommended monitoring requirements are detailed below.

5.2 Waste Management and Control

5.2.1 Construction Phase

5.2.1.1 Mitigation measures for waste management as recommended in the EIA Report are summarised below. With proper handling, storage and disposal of waste arisings during the construction phase of the Project, the potential to cause adverse environmental impacts would be minimized.

Good Site Practices

5.2.1.2 Adverse environmental impacts in relation to waste management are not expected, provided that good site practices are strictly followed. Recommendations for good site practices during the construction activities would include:

� Obtain relevant waste disposal permits from appropriate authorities, in accordance with the Waste Disposal Ordinance (Cap. 354) and subsidiary Regulations and the Land (Miscellaneous Provisions) Ordinance (Cap. 28);

� Provide staff training for proper waste management and chemical handling procedures;

� Provide sufficient waste disposal points and regular waste collection;

� Provide appropriate measures to minimise windblown litter and dust during transportation of waste by either covering trucks or by transporting wastes in enclosed containers;

� Carry out regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors;

� Separate chemical wastes for special handling and disposed of to licensed facility for treatment; and

� Employ licensed waste collector to collect waste.

Waste Reduction Measures

5.2.1.3 Good management and control can prevent the generation of a significant amount of waste. Waste reduction is best achieved at the planning and design stage, as well as by ensuring the implementation of good site practices. Recommendations to achieve waste reduction include:

� Design foundation works that could minimise the amount of excavated material to be generated;

� Provide training to workers on the importance of site cleanliness and appropriate waste management procedures, including waste reduction, reuse and recycling;

� Sort out demolition debris and excavated materials from demolition works to recover reusable/recyclable portions (i.e. soil, broken concrete, metal, etc.);

� Segregate and store different types of waste in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal;

� Encourage the collection of aluminium cans by providing separate labelled bins to enable this waste to be segregated from other general refuse generated by the work force;

� Proper storage and site practices to minimise the potential for damage or contamination of construction materials; and

� Plan and stock construction materials carefully to minimise amount of waste to be generated and to avoid unnecessary generation of waste.

5.2.1.4 In addition to the above measures, specific mitigation measures are recommended below for the identified waste so as to minimize environmental impacts during handling, transportation and disposal of the waste.

Dredged Sediments

5.2.1.5 The basic requirements and procedures for dredged sediment disposal specified under ETWB TCW 34/2002 shall be followed. According to the ETWB TCW 34/2002, the Marine Fill Committee (MFC) is responsible for managing the disposal facilities in Hong Kong for the dredged sediment, while EPD is the authority of issuing marine dumping permit under the DASO.

5.2.1.6 The project proponent should agree in advance with MFC of CEDD on the site allocation. The project proponent or contractor for the dredging works shall then apply for the site allocations of marine sediment disposal based on the prior agreement with MFC/CEDD. The project proponent or contractor should also be responsible for the application of all necessary permits from relevant authorities, including the dumping permit as required under DASO from EPD, for the disposal of dredged sediment prior to the commencement of the dredging works.

5.2.1.7 As part of Section 5.2.1.6 above, the project proponent or contractor will need to satisfy the appropriate authorities that the quality of the marine sediment to be dredged has been identified according to the requirements of ETWB TCW 34/2002. This should be completed well before the dredging works and would include at least the submission of a formal Sediment Quality Report under Tier I of ETWB TCW No. 34/2002 to DEP for approval. Subject to advice from DEP, it is possible that further marine SI in accordance with ETWB TCW 34/2002 might be necessary for the application of dumping permit under DASO. In such case, a sediment sampling and testing proposal shall be submitted to and approved by DEP before the additional marine SI works.

5.2.1.8 The dredged marine sediments would be loaded onto barges, transported to and disposed of at the designated disposal sites (subject to agreement with MFC and given Type 1 sediment were identified, the disposal sites are typically South Cheung Chau and/or East of Ninepin as open sea disposal). In addition to the mitigation measures as discussed in the EIA report, the barge transporting the sediments to the designated disposal sites should be equipped with tight fitting seals to prevent leakage and should not be filled to a level that would cause overflow of materials or laden water during loading or transportation. In addition, monitoring of the barge loading shall be conducted to ensure that loss of material does not take place during transportation. Transport barges or vessels shall be equipped with automatic self-monitoring devices as specified by the DEP.

Construction and Demolition Materials

5.2.1.9 In order to minimize the impact resulting from collection and transportation of C&D materials for off-site disposal, the excavated material arising from site formation and foundation works should be reused on-site as backfilling material and for landscaping works as far as practicable. Other mitigation requirements are listed below:

� A Waste Management Plan (WMP), which becomes part of the Environmental Management Plan (EMP), should be prepared in accordance with ETWB TCW No.19/2005;

� A recording system for the amount of wastes generated, recycled and disposed (including the disposal sites) should be adopted for easy tracking; and

� In order to monitor the disposal of C&D materials at public filling facilities and landfills and to control fly-tipping, a trip-ticket system should be adopted (refer to ETWB TCW No. 31/2004).

5.2.1.10The Contactor should prepare and implement an EMP in accordance with ETWB TCW No.19/2005, which describes the arrangements for avoidance, reuse, recovery, recycling, storage, collection, treatment and disposal of different categories of waste to be generated from construction activities. Such a management plan should incorporate site specific factors, such as the designation of areas for segregation and temporary storage of reusable and recyclable materials. The EMP should be submitted to the ER for approval. The Contractor should implement waste management practices in the EMP throughout the construction stage of the Project. The EMP should be reviewed regularly and updated by the Contractor, preferably on a monthly basis.

5.2.1.11All surplus C&D materials arising from or in connection with construction works should become the property of the Contractor when it is removed unless otherwise stated. The Contractor would be responsible for devising a system to work for on-site sorting of C&D materials and promptly removing all sorted and process materials arising from the construction activities to minimize temporary stockpiling on-site. The system should be included in the EMP identifying the source of generation, estimated quantity, arrangement for on-site sorting, collection, temporary storage areas and frequency of collection by recycling Contractors or frequency of removal off-site.

Chemical Wastes

5.2.1.12Should chemical wastes be produced at the construction site, the Contractor would be required to register with 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 employ 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.

General Refuse

5.2.1.13General refuse should be stored in enclosed bins or compaction units separate from C&D materials. A licensed waste collector should be employed by the Contractor to remove general refuse from the site, separately from C&D materials. Preferably an enclosed and covered area should be provided to reduce the occurrence of �wind blown� light material.

5.2.2 Operational Phase

Good Site Practices

5.2.2.1 It is recommended that the following good operational practices should be adopted to minimize waste management impacts:

� Obtain the necessary waste disposal permits from the appropriate authorities, in accordance with the Waste Disposal Ordinance (Cap. 354) and Waste Disposal (Chemical Waste) (General) Regulation;

� Nomination of an approved person to be responsible for good site practice, arrangements for collection and effective disposal to an appropriate facility of all wastes generated at the site;

� Use of a waste haulier licensed to collect specific category of waste;

� A trip-ticket system should be included as one of the contractual requirements and implemented by the Environmental Team to monitor the disposal of solid wastes at landfills, and to control fly tipping. Reference should be made to ETWB TCW No. 31/2004;

� Training of site personnel in proper waste management and chemical waste handling procedures;

� Separation of chemical wastes for special handling and appropriate treatment at a licensed facility;

� Routine cleaning and maintenance programme for drainage systems, sumps and oil interceptors;

� Provision of sufficient waste disposal points and regular collection for disposal;

� Adoption of appropriate measures to minimize windblown litter and dust during transportation of waste, such as covering trucks or transporting wastes in enclosed containers; and

� Implementation of a recording system for the amount of wastes generated, recycled and disposed of (including the disposal sites).

Waste Reduction Measures

5.2.2.2 Good management and control can prevent the generation of significant amounts of waste. It is recommended that the following good operational practices should be adopted to ensure waste reduction:

� Segregation and storage of different types of waste in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal;

� Encourage collection of aluminium cans, plastic bottles and packaging material (e.g. carton boxes) and office paper by individual collectors. Separate labelled bins should be provided to help segregate this waste from other general refuse generated by the work force; and

� Any unused chemicals or those with remaining functional capacity should be reused as far as practicable.

Storage, Handling, Treatment, Collection and Disposal of Incineration By-Products

5.2.2.3 The following measures are recommended for the storage, handling and collection of the incineration by-products:

� Ash should be stored in storage silos;

� Ash should be handled and conveyed in closed systems fully segregated from the ambient environment;

� Ash should be wetted with water to control fugitive dust, where necessary;

� All fly ash and air pollution control (APC) residues should be treated, e.g. by cement solidification or chemical stabilization, for compliance with the proposed Incineration Residue Pollution Control Limits and leachability criteria prior to disposal;

� The ash should be transported in covered trucks or containers to the designated landfill site.

5.2.2.4 The Contractor should provide EPD with chemical analysis results of the bottom ash, and treated fly ash and APC residues to confirm that the ash/residue can comply with the proposed Incineration Residue Pollution Control Limits before disposal.

5.3 Monitoring Requirements for Biogas Generation

5.3.1 If the biogas monitoring is required, monitoring should be undertaken via purposely installed monitoring wells within boreholes drilled into the fill material. The boreholes should be drilled down to the level of the groundwater (mean sea water level) and standard landfill gas-type monitoring wells installed. These should be fitted with a removable cap and gas monitoring valve so that gas concentrations as well as flow rates may be measured from the open well. During the drilling of boreholes, the safety and working procedures described in the Landfill Gas Hazard Assessment Guidance Note, EPD (1997) should be followed.

5.3.2 Concentrations of methane gas should be measured using portable gas monitoring instruments, as described in Section 5.3.4. Fluxes should also be measured if the emission velocities are not too low. It is recommended that monitoring be undertaken bi-weekly for a period of at least 3 months (preferably 6 months or more) prior to the commencement of construction works on the reclamation. The results of the gas monitoring should be reviewed to determine whether the length of the monitoring period should be extended. It is also recommended that gas flow rates from the wells be monitored under different meteorological conditions and to include some occasions when atmospheric pressure is falling quite quickly (e.g. immediately preceding a typhoon).

5.3.3 Where possible, it is recommended that monitoring wells be located in areas designated for open space as it may be possible to continue monitoring at these locations throughout the construction period. Monitoring wells should be located away from the areas dredged for the permanent stormwater culvert and the temporary channel/culvert construction.

5.3.4 Monitoring shall be carried out using intrinsically safe, portable gas monitoring instruments. The gas monitoring instrument shall:

� Be capable of continuous monitoring of methane;

� Be capable of continuous barometric pressure and gas pressure measurements;

� Be capable of monitoring temperature of the gas;

� Where possible, comply with BS6020 and be approved by BASEEFA as intrinsically safe, suitable for use in a Zone 2 area to BS5345;

� Normally operate in diffusion mode unless required for spot sampling, when it should be capable of operating by means of an aspirator or pump;

� Display any parameters monitored by clear unambiguous readings given on an alpha numeric display LCD screen with wide angle viewing;

� Have low battery, fault and over range indication incorporated;

� Store monitoring date, and shall be capable of being down-loaded directly to a PC;

� Measure in the following ranges:

Methane	0-100% LEL & 0-100% v/v
Barometric pressure	mBar (absolute)
Gas pressure (relative to atmospheric)	Pascals atmospheric
temperature	0-100�C

� Have removable and rechargeable batteries with more than 12 hours continuous operating life;

� Have back-up batteries; and

� Have an oxygen sensor with a life of not less than twelve months and other sensors shall have a life of more than two years before deterioration in performance of the sensor.

5.3.5 To measure the gas flow rates from the open monitoring wells, very sensitive techniques (such as micro-anemometer) will need to be used to measure the anticipated very low flow rates.

5.3.6 The gas monitoring equipment shall be calibrated and maintained in accordance with the manufacturer�s recommendations for calibration and maintenance.

5.3.7 Prior to entry of any below ground service voids, chambers or any confined environment, the atmosphere within the chamber should be checked for oxygen, methane and carbon dioxide concentrations. The chamber may then only be entered if oxygen is greater than 18% by volume, methane is less than 10% of the Lower Explosive Limit (LEL), which is equivalent to 0.5% by volume (approximately), and carbon dioxide is less than 0.5% by volume. If either carbon dioxide or methane is higher, or oxygen lower than the values given above, then entry to the chamber should be prohibited and expert advice sought. Even if conditions are safe for entry, no worker should be permitted to enter the chamber without having another worker present at the surface. The worker who enters the chamber should wear an appropriate safety/recovery harness and, preferably, should carry a portable methane, carbon dioxide and oxygen meter.

In general, when work is being undertaken in confined spaces sufficient approved resuscitation equipment, breathing apparatus and safety torches should be available. Persons involved in or supervising such work should be trained and practiced in the use of such equipment. A permit-to-work system for entry into confined spaces should be developed by an appropriately qualified person and consistently employed.

5.4 Approach to Prevent Land Contamination

5.4.1 Fuel Oil Spillage Prevention

Precautionary measures to prevent fuel oil spillage are presented below.

5.4.1.1 Fuel Oil Tank Construction and Test

� The fuel tank to be installed should be of specified durability.

� Double skin tanks are preferred.

� Underground fuel storage tank should be placed within a concrete pit.

� The concrete pit shall be accessible to allow regular tank integrity tests to be carried out at regular intervals.

� Tank integrity tests should be conducted by an independent qualified surveyor or structural engineer.

� Any potential problems identified in the test should be rectified as soon as possible.

5.4.1.2 Fuel Oil Pipeline Construction and Test

� Installation of aboveground fuel oil pipelines is preferable; if underground pipelines are unavoidable, concrete lined trenches should be constructed to contain the pipelines.

� Double skin pipelines are preferred.

� Distance between the fuel oil refuelling points and the fuel oil storage tank shall be minimized.

� Integrity tests for the pipelines should be conducted by an independent qualified surveyor or structural engineer at regular intervals.

� Any potential problems identified in the test should be rectified as soon as possible.

5.4.1.3 Fuel Oil Leakage Detection

� Installation of leak detection device at storage tank and pipelines.

� Installation and use of pressure gauges (e.g. at the two ends of a filling line) in fuel filling, which allows unexpected pressure drop or difference and sign of leakage to be detected.

5.4.1.4 Fuel Oil Storage Tank Refuelling

� Storage tank refuelling (from road tanker) should only be conducted by authorized staff of the oil company using the company�s standard procedures.

5.4.1.5 Fuel Oil Spillage Response

� An Oil Spill Response Plan should be prepared by the operator to document the appropriate response procedures for oil spillage incidents in detail. General procedures to be taken in case of fuel oil spillage are presented below.

� Training

Training on oil spill response actions should be given to relevant staff. The training shall cover the followings:

- Tools & resources to combat oil spillage and fire, e.g. locations of oil spill handling equipment and firefighting equipment;

- General methods to deal with oil spillage and fire incidents;

- Procedures for emergency drills in the event of oil spills and fire; and

- Regular drills shall be carried out.

� Communication

Establish communication channel with the Fire Services Department (FSD) and EPD to report any oil spillage incident so that necessary assistance from relevant department can be quickly sought.

� Response Procedures

Any fuel oil spillage within the IWMF site should be immediately reported to the Plant Manager with necessary details including location, source, possible cause and extent of the spillage.

Plant Manager should immediately attend to the spillage and initiate any appropriate action to confine and clean up the spillage. The response procedures shall include the following:

- Identify and isolate the source of spillage as soon as possible.

- Contain the oil spillage and avoid infiltration into soil/ groundwater and discharge to storm water channels.

- Remove the oil spillage.

- Clean up the contaminated area.

- If the oil spillage occurs during storage tank refuelling, the refueling operation should immediately be stopped.

- Recovered contaminated fuel oil and the associated material to remove the spilled oil should be considered as chemical waste. The handling and disposal procedures for chemical wastes are discussed in the following paragraphs.

5.4.2 Chemicals and Chemical Wastes Handling & Spillage Prevention

The precautionary measures to prevent improper handling/ use of chemicals and chemical waste spillage are presented below.

5.4.2.1 Chemicals and Chemical Wastes Handling & Storage

� Chemicals and chemical wastes should only be stored in suitable containers in purpose-built areas.

� The storage of chemical wastes should comply with the requirements of the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes.

� The storage areas for chemicals and chemical wastes shall have an impermeable floor or surface. The impermeable floor/ surface shall possess the following properties:

� Not liable to chemically react with the materials and their containers to be stored.

� Able to withstand normal loading and physical damage caused by container handling.

� The integrity and condition of the impermeable floor or surface should be inspected at regular intervals to ensure that it is satisfactorily maintained.

� For liquid chemicals and chemical wastes storage, the storage area should be bunded to contain at least 110% of the storage capacity of the largest containers or 20% of the total quantity of the chemicals/chemical wastes stored, whichever is the greater.

� Storage containers shall be checked at regular intervals for their structural integrity and to ensure that the caps or fill points are tightly closed.

� Chemical handling shall be conducted by trained workers under supervision.

5.4.2.2 Chemicals and Chemical Wastes Spillage Response

- Clean up the contaminated area (in case the spillage occurs at locations out of the designated storage areas); and

- The waste arising from the cleanup operation should be considered as chemical wastes.

5.4.3 Preventive Measures for Incineration By-products Handling

5.4.3.1 The recommended measures listed below can minimize the potential contamination to the surrounding environment due to the incineration by-products:

� Ash should be stored in storage silos;

� Ash should be handled and conveyed in closed systems fully segregated from the ambient environment;

� Ash should be wetted with water to control fugitive dust, where necessary;

� All fly ash and APC residues should be treated, e.g. by cement solidification or chemical stabilization, for compliance with the proposed Incineration Residue Pollution Control Limits and leachability criteria prior to disposal;

� The ash should be transported in covered trucks or containers to the designated landfill site.

5.4.4 Incident Record

5.4.4.1 After any spillage, an incident report should be prepared by the Plant Manager. The incident report should contain details of the incident including the cause of the incident, the material spilled and estimated spillage amount, and also the response actions undertaken. The incident record should be kept carefully and able to be retrieved when necessary.

5.4.4.2 The incident report should provide sufficient details for the evaluation of any environmental impacts due to the spillage and assessment of the effectiveness of measures taken.

5.4.4.3 In case any spillage or accidents results in significant land contamination, EPD should be informed immediately and the Contractor should be responsible for the cleanup of the affected area.

6 ECOLOGICAL IMPACT

6.1 Introduction

6.1.1 The EIA report has identified the proposed Project Site as an important habitat for Finless Porpoise. The shoreline within the study area was also identified to be supporting 15 coral species (8 hard corals and 7 octocorals). An active nest of White-bellied Sea Eagle (WBSE) had been previously recorded at the southwest of Shek Kwu Chau within hillside shrubland. Adverse impacts on the habitats of Finless Porpoise, coral communities, and the nest of WBSE have been predicted due to the proposed Project.

6.1.2 Specific mitigation measures have been recommended for Finless Porpoise, corals, and WBSE in the EIA report, with the aim to minimize potential direct and indirect impacts. With the implementation of the recommended measures, adverse impacts from the construction and operation of the proposed Project on the concerned fauna groups should be minimized.

6.1.3 This section describes the specific mitigation measures and the requirements for monitoring and auditing recommended for Finless Porpoise, corals, and WBSE.

6.2 Ecological Mitigation Measures

6.2.1 Specific Measures to Minimize Disturbance on Finless Porpoise

Minimisation of habitat loss for Finless Porpoise

6.2.1.1 In order to minimize the potential loss of important habitat for Finless Porpoise, substantial revision has been made on the layout plan of the breakwater. The revised layout of the breakwater has greatly reduced the size of the embayment area. Moreover, the newly proposed breakwater form (circular cells) has also reduced the size of the footprint. As a result, the total habitat loss (including reclamation and embayment) for Finless Porpoise has reduced from ~50 ha, down to ~31 ha.

Avoidance of peak season for Finless Porpoise occurrence

6.2.1.2 In order to minimize potential acoustic disturbance from construction activities on Finless Porpoise, construction works that may produce underwater acoustic disturbance should be scheduled outside the months with peak Finless Porpoise occurrence (December to May), including:

� sheet piling works for construction of cofferdam surrounding the reclamation area (Phase 1);

� sheet piling works for construction of the shorter section of breakwater (Phase 1);

� sheet piling works for construction of the remaining section of breakwater (Phase 3);

� bored piling works for berth area (Phase 3); and

6.2.1.3 Such works should be restricted within June to November. This approach would not only avoid the peak season for Finless Porpoise occurrence, the magnitude of impacts arise from acoustic disturbance would also be minimized.

Opt for quieter construction methods and plants

6.2.1.4 In order to minimize underwater acoustic disturbance on Finless Porpoise, quieter construction methods and plants should be adopted:

� Considering the sensitivity of marine mammals to underwater acoustic disturbance, instead of the previously proposed conventional breakwater and reclamation peripheral structure, which requires noisy piling works, the current circular cells structure for breakwater and reclamation peripheral structure is proposed. A quieter sheet piling method using vibratory hammer or hydraulic impact hammer, would be adopted for the installation of circular cells for cellular cofferdam and northern breakwater during Phase 1, and southern breakwater Phase 3;

� Non-percussive bore piling method would be adopted for the installation of tubular piles for the berth construction during Phase 3.

Monitored exclusion zones

6.2.1.5 A monitored exclusion zone of 250m radius from silt curtain or from the boundary of a work area should be implemented under the following situations (where applicable, Marine Mammal Watching Plan shall be conducted at the meantime) :

i. 30 minutes before the commencement of installation / re-installation / relocation works of floating type silt curtain at marine access; and

ii. 2. MMEZ monitoring during installation / re-installation / relocation of floating types silt curtain when opening and closing at marine access area; and

iii. 3. After the enclosure of floating type silt curtain at marine access area for reclamation works to implement visual inspection as detailed in Marine Mammal Watching Plan.

6.2.1.6 If a marine mammal is noted within the exclusion zone, all marine works should stop immediately and remain idle for 30 minutes, or until the exclusion zone is free from marine mammals.

6.2.1.7 The experienced marine mammal observer should be well trained to detect marine mammals. Binoculars should be used to search the exclusion zone from an elevated platform with unobstructed visibility. The observer should also be independent from the project proponent and has the power to call-off construction activities.

6.2.1.8 In addition, as marine mammals cannot be effectively monitored within the proposed monitored exclusion zone at night, or during adverse weather conditions (i.e. Beaufort 5 or above, visibility of 300 meters or below), marine works should be avoided under weather conditions with low visibility.

Marine mammal watching plan

6.2.1.9 Upon the completion of silt curtain installation / re-installation / relocation, the marine works would be conducted within an enclosed environment within the silt curtain. Subsequently, the plan would include Visual Inspectrion of the Waters Surrounded by Silt Curtains (Section 2.1, MMWP) and Regular Inspection of the Deployed Silt Curtain (Section 2.1, MMWP) inspection under Marine Mammal Watching Plan (MMWP) would be implemented (where applicable, Marine Mammal Exclusion Zone shall be conducted at the meantime). Special attention would be paid to Phase 2 (reclamation) where the floating type still curtain would be opened occasionally for vessel access, leaving a temporary 50 m opening. An action plan should be devised to cope with any unpredicted incidents such as the case when marine mammals are found within the waters surrounded by the silt curtains.

Small openings at silt curtains

6.2.1.10In order to avoid the entrance of marine mammals into the works area through the opening at silt curtains for vessel access, and the subsequent potential impacts including increase in stress level in marine mammals due to underwater noise and chance of collision with working vessels, the openings for vessel access at the silt curtains should be as small as possible to minimize the risk of accidental entrance.

Adoption of regular travel route

6.2.1.11In order to minimize the disruption on marine mammal�s behavioural pattern during construction and operation phases, captains of all vessels should adopt regular travel route, in order to minimize the chance of vessel collision with marine mammals, which may otherwise result in damage to health or mortality.

6.2.1.12The regular travel route should avoid areas with high sighting density of Finless Porpoise as much as possible, as indicated in the latest Monitoring of Marine Mammals in Hong Kong Waters (AFCD, 2010a). With the adoption of regular travel route, potential alteration in behavioural pattern of marine mammals due to increase in marine traffic is considered to be acceptable.

Vessel speed limit

6.2.1.13In order to minimize potential injury and mortality of marine mammals due to collision with vessels during construction (working vessels) and operation phase (4round trips/day for MSW vessel, and 12 round trips/day for visitor/staff shuttle ferry), a speed limit of ten knots should be strictly enforced within areas with high density of Finless Porpoise, as identified in the latest Monitoring of Marine Mammals in Hong Kong Waters (AFCD, 2017). The recommend area where speed limit should be adopted include the grids Q30, Q31, and R31 (Figure 6.2).

6.2.1.14The same speed limit has been enforced within the Sha Chau and Lung Kwu Chau marine park, and adopted under the EIA-172/2009 Hong Kong - Zhuhai - Macao Bridge Hong Kong Link Road (HyD, 2009a), where density of Chinese White Dolphin is high. Limitation on vessel speed limit has appeared to be effective in protecting dolphins from vessel collision, as well as minimizing underwater acoustic disturbance. With the adoption of these mitigation measures, the potential impact marine mammals due to injury and mortality from vessel collision would be minimized to acceptable level.

6.2.1.15Passive acoustic monitoring and land-based theodolite monitoring surveys should be adopted to verify the predicted impacts and effectiveness of the proposed mitigation measures.

Training of staff

6.2.1.16In order to ensure that all staff, including captains of vessels, are aware of the guidelines for safe vessel operations in the presence of cetaceans during construction and operation phases, adequate trainings should be provided.

Designation of Marine Park

6.2.1.17Loss of 31 ha of marine habitat would be permanently resulted from the reclamation and breakwater construction at the southwestern waters of Shek Kwu Chau. The proposed works area is of high ecological value, as it is identified as an important habitat for Finless Porpoise; hence high level of adverse impact is predicted. As minimization measures are exhausted, compensatory measure is therefore required.

6.2.1.18According to the Finless Porpoise data recorded between 2016 to 2017 (AFCD, 2017), the waters between Shek Kwu Chau and Soko Islands is the nearest area to the proposed Project that has high sighting concentration of Finless Porpoise than the rest of the nearby waters. In addition, the extent of Finless Porpoise habitat is the most continuous and connected to other nearby important habitats of marine mammals, i.e. Soko Islands, which has records of both Finless Porpoise and Chinese White Dolphin.

6.2.1.19The Project Proponent has made a firm commitment to seek to designate an approximate area of 700 ha in the waters between Soko Islands and Shek Kwu Chau as a marine park, in accordance with the statutory process stipulated in the Marine Parks Ordinance, as a compensation measure for the habitat loss arising from the construction of the IWMF at an artificial island near SKC.

6.2.1.20The firm commitment to seek to designate the marine park, where incompatible activities would be regulated and proper management regime imposed in accordance with the Marine Park Ordinance, would significantly help conserve Finless Porpoise, and hence serve as an effective compensation measure for the permanent loss of Finless Porpoise habitat arising from the project. The Project Proponent shall seek to complete the designation by 2018 to tie in with the operation of the IWMF at an artificial island near SKC.

6.2.1.21A further study should be carried out to review relevant previous studies and collate available information on the ecological characters of the proposed area for marine park designation; and review available survey data for Finless Porpoise, water quality, fisheries, marine traffic and planned development projects in the vicinity. Based on the findings, ecological profiles of the proposed area for marine park designation should be established, and the extent and location of the proposed marine park be determined. The adequacy of enhancement measures should also be reviewed.

6.2.1.22In addition, a management plan for the proposed marine park should be proposed, covering information on the responsible departments for operation and management (O&M) of the marine park, as well as the O&M duties of each of the departments involved. Consultation with relevant government departments and stakeholders should be conducted under the study. The study should be submitted to Director of Environmental Protection (DEP) for approval before the commencement of construction works.

6.2.1.23The Project Proponent should provide assistance to AFCD during the process of the marine park designation.

6.2.2 Specific Measures to Minimize Impact on Corals

Coral translocation

6.2.2.1 According to the results of the existing REA surveys, all 198 coral colonies to be directly affected by the proposed Project were attached to movable rocks, which are less than 50 cm in diameter. Translocation of the potentially affected corals is technically feasible to avoid direct loss. With the implementation of coral translocation prior to the construction works, no loss of coral colonies would be expected. Coral translocation should be carried out during the winter season (November to March) in order to avoid the spawning season of corals (July to October) (Lam, 2000; Storlazzi, 2004). The health status of translocated corals should be regularly monitored after the translocation works.

6.2.2.2 Prior to coral translocation, a more detailed baseline survey, including a coral mapping survey, is recommended to further confirm the exact number and location of coral colonies within the potentially affected area. A more detailed Coral Translocation Plan, including selection of suitable recipient site, plan for coral translocation, and event / action plan for coral monitoring had been submitted upon approval of this Project, prior to commencement of construction works. Advice from relevant governmental departments (e.g. AFCD) and professionals were sought after, in order to identify a desirable location for the relocation of coral communities. Post-translocation monitoring on the translocated corals should also be considered.

6.2.2.3 The selection of recipient site suitable for the affected corals is important. To increase the survival rate of the translocated corals, the following criteria for selecting a suitable coral recipient site are recommended:

� Presence of same coral species with similar coral community as the donor site;

� Similar environmental conditions such as light intensity, salinity, hydrographic condition and bathymetry as the donor site;

� Presence of suitable substratum to allow the translocated boulders/rocks to be permanently stabilised; and

� Presence of protection from storm/typhoon damage.

6.2.2.4 The translocation work should be led by qualified coral specialist(s) who preferably have coral translocation experience.

Coral monitoring programme

6.2.2.5 A coral monitoring programme is recommended to assess any adverse and unacceptable impacts to the coral communities at the coasts of Shek Kwu Chau during construction of the Project.

6.2.3 Specific Measures to Minimize Disturbance on Breeding White-bellied Sea Eagle

Avoidance of noisy works during the breeding season of White-bellied Sea Eagle

6.2.3.1 In order to minimize potential construction noise disturbance on White-bellied Sea Eagle (WBSE) to acceptable level, noisy construction works should be scheduled outside their breeding season (December to May) to minimize potential degradation in breeding ground quality and breeding activities. Works that are recommended to adopt such measure include:

� sheet piling works for construction of cofferdam surrounding the reclamation area (Phase 1);

� sheet piling works for construction of the shorter section of breakwater (Phase 1);

� sheet piling works for construction of the remaining section of breakwater (Phase 3); and

� bored piling works for berth area (Phase 3).

Opt for quieter construction methods and plants

6.2.3.2 In order to minimize potential construction noise disturbance on WBSE, quieter construction methods and plants should be adopted. The recommended noise mitigation measures in should be implemented to minimize potential noise disturbance to acceptable levels.

Restriction on vessel access near the nest of White-bellied Sea Eagle

6.2.3.3 During construction and operation, in order to minimize disturbance on the existing WBSE nest, a pre-defined practical route to restrict vessel access near the nest should be adopted to keep vessels and boats as far away from the nest as possible. As mentioned previously, WBSE are known to be sensitive to human disturbance during the breeding season, and may even desert a nest if disturbed. As an additional precautionary measure to minimize disturbance on their nestling stage, the vessel travel route should be adjusted to avoid the foraging ground of the breeding adult birds identified during WBSE monitoring programme. If avoidance of foraging ground is not feasible, vessel frequency and speed within their foraging ground near the construction area should be reduced to minimize any potential impacts.

White-bellied Sea Eagle monitoring programme

6.2.3.4 A WBSE monitoring programme is recommended to assess any adverse and unacceptable impacts to the breeding activities of WBSE during construction and operation of the Project. Monitoring surveys for WBSE would include pre-construction phase, construction phase and operation phase. More details on monitoring for WBSE are presented in Section 6.5.

Education of staff

6.2.3.5 Staff, including captains of all vessels during construction and operation phased, should be aware of the ecological importance of WBSE. Awareness should be raised among staff to minimize any intentional or unintentional disturbance to the nest.

Minimisation of Glare Disturbance

6.2.3.6 To minimize glare disturbance on WBSE, which may cause disorientation of birds by interfering with their magnetic compass, and disruption in behavioural patterns such as reproduction, fat storage and foraging pattern, any un-necessary outdoor lighting should be avoided, and in-ward and down-ward pointing of lights should be adopted.

6.3 Marine Mammal Monitoring

6.3.1 Introduction

6.3.1.1 The marine mammal monitoring programme would focus on Finless Porpoise, as the study area has been identified as a hotspot for this species. The monitoring would verify the predicted impacts, and examine whether the mitigation measures recommended in the EIA report have been effectively implemented to protect marine mammals from negative impacts from construction activities.

6.3.2 Vessel-based Line-transect Survey

6.3.2.1 The survey methodology should remain the same as that adopted during the EIA study to allow fair comparison of marine mammal line transect surveys (Figure 6.1), as well as the proposed marine park for the compensation of loss of important habitat for Finless Porpoise. The marine mammal monitoring programme should cover pre-construction phase, construction phase and operation phase.

6.3.2.2 To determine the baseline condition of Finless Porpoise occurrence in the study area, pre-construction phase monitoring of Finless Porpoise should be conducted twice a month for the duration of three months (any three months within the peak season for Finless Porpoise occurrence � December to May) before the commencement of works. Throughout the construction phase involving marine construction works, monitoring of Finless Porpoise should be conducted twice per month during the peak season for Finless Porpoise, and once per month during the off-peak season. For operation phase, monitoring of Finless Porpoise should last for 1 year, following the survey frequency adopted during construction phase.

6.3.2.3 For construction and operation phase monitoring, surveys for all 4 seasons should be covered, in order to take natural fluctuation and seasonal variations into account for data analysis of distribution, encounter rate, density and habitat use of both porpoises and dolphins (if any). After analysis of the data, the results would allow the detection of any changes of their usage of habitat, in response to the proposed construction works.

6.3.2.4 The line-transect monitoring survey should be led by suitably qualified persons with recognizable experience in marine mammal monitoring survey. The methodology for marine mammal monitoring should be consulted with the Agriculture, Fisheries and Conservation Department (AFCD) before the commencement of the monitoring programme.

6.3.2.5 Two experienced observers, a data recorder and a primary observer, should make up the on-effort survey team. The survey vessel should transit different transect lines at a constant speed of 13-15 km per hour. The data recorder should search for signs of marine mammals with unaided eye and fills out the datasheets; and the primary observer should search continuously through a pair of marine binoculars. Both observers should search the sea ahead of the vessel, between 270o and 90o (in relation to the bow, which is defined as 0o).

6.3.2.6 During on-effort survey periods, the survey team should record effort data including time, position (latitude and longitude), weather conditions (Beaufort sea state and visibility) and distance travelled in each series (a continuous period of search effort), with the assistance of a professional GPS. Two additional experienced observers should be available on the boat to work in shift (i.e. rotate every 30 minutes), in order to minimize fatigue of the survey team members.

6.3.2.7 When marine mammals are sighted, the survey team should end the survey effort, and immediately record the initial sighting distance and angle of the dolphin group from the survey vessel, as well as sighting time and position. The research vessel should then divert from its course to approach the animals for species identification, group size estimation, group composition assessment, behavioural observations, and collection of identification photos. The perpendicular distances (PSD) of the dolphin groups to the transect line should be calculated from the initial sighting distance and angle.

6.3.3 Passive Acoustic Monitoring

6.3.3.1 Passive acoustic monitoring aims to study the 24-hour usage of an area by Finless Porpoise by using automated static porpoise detectors (C-PODs) which will be deployed at different locations to detect the unique ultra-high frequency sounds produced by the porpoises. One porpoise detector will be placed within the Project Area, while other two porpoise detectors would be placed outside the Project Area as control sites. The locations of the two control sites (i.e. within Pui O Wan and to the south of Tai A Chau) were specifically chosen, as these control sites were regularly visited by the porpoises based on past AFCD long-term monitoring data, and were also confirmed by the professional team on the feasibility for deployment and retrieval of the C-POD units. These three detectors will be left on-site to carry out 24-hours monitoring over the 30-day monitoring period during the peak occurrence period of Finless Porpoise (December to May) during pre-construction, construction and operation phase so as to obtain an overview on utilization of the Project Area by the porpoises and to identify any difference between work stages.

6.3.3.2 The final number, position, and duration of the porpoise detector deployment should be agreed with AFCD.

6.3.4 Active Acoustic Monitoring

6.3.4.1 Active acoustic monitoring aims to study the acoustic behaviour of Finless Porpoise in relation to the presence and absence of vessels, and their associated underwater acoustic disturbance. Hydrophones should be deployed from stationary boat to record noise data from vessels and Finless Porpoise.

6.3.4.2 With the recorded data, analysis on whether presence of, and distance from vessel traffic would cause acoustic behavioural changes in Finless Porpoise, or changes in use off frequency range etc. could be determined. The results should be used to verify the predicted impacts and the effectiveness of the proposed mitigation measures.

6.3.4.3 Approximately 30 days of field work should be carried out during the peak occurrence period of Finless Porpoise (December to May), with the main focus on operation phase where traffic of MSW vessels and visitor/staff shuttle ferry is regular. Details of the active acoustic monitoring methodology and frequency should be agreed with AFCD.

6.3.5 Land-based Theodolite Tracking

6.3.5.1 Land-based Theodolite Tracking will be carried out for 30 days on site during the peak occurrence period of Finless Porpoise (December to May). The survey should cover pre-construction phase, construction and operation phases. Six hours of theodolite tracking should be conducted for each day of the baseline field survey in which the theodolite station should be set up at the south of SKC from an un-obstructed vantage point at a height above the monitoring area. Our monitoring team consists of one experienced theodolite operator and at least two field observers for assistance. To conduct theodolite tracking, our observers will search systematically for Finless Porpoise using the unaided eye and 7 x 50 handheld binoculars on each survey day throughout the study area. When an individual or group of porpoises is located, a theodolite tracking session will be initiated and focal follow methods will be used to track the porpoise(s). Behavioural state data (i.e. resting, milling, travelling, feeding and socializing) will also be recorded every 5 minutes for the focal individual or group. Positions of porpoises and boats will be measured using a digital theodolite connected to a laptop computer to provide information on the target�s distance from shore, depth of water, distance from anthropogenic activities, and relative speeds and orientations; as well as measurements of leg (one point to other) speeds, re-orientations, distance made-good over time, and other movement related parameters.

6.3.6 Land-based Monitoring of Channel between the IWMF and Shek Kwu Chau

6.3.6.1 Although the trapping of marine mammals within the channel was predicted to be unlikely in the EIA report; however in view of their conservation importance, precautionary landbased monitoring of channel for potential trapping of marine mammals by site staff during operation phase should be adopted to verify the impact predication. The monitoring frequency should be once per week for duration of one year during operation phase.

6.3.6.2 Should any trapping occurs, the site staff must contact responsible parties immediately, i.e. AFCD or specialist, for rescue

6.3.7 Marine Mammal Exclusion Zone (MMEZ)

6.3.7.1 A monitored exclusion zone of 250m radius from silt curtain or from the boundary of a work area should be implemented under the following situations (where applicable, Marine Mammal Watching Plan shall be conducted at the meantime) :

i. 30 minutes before commencement of and during silt curtain installation / re-installation / relocation, deep cement mixing injection works or noisy construction works (as stipulated in FEP Clause 2.25 and 2.27);

ii. MMEZ monitoring during installation / re-installation / relocation of floating types silt curtain when opening and closing at marine access area; and

iii. After the enclosure of floating type silt curtain at marine access area for reclamation works to implement visual inspection as detailed in paragraphs below.

The MMEZ will be carried out in order to avoid the accidental entrance and entrapment of marine mammals within the silt curtains or works area and minimize underwater acoustic disturbance, so as for precautionary purpose for DCM works. If a marine mammal is noted within the exclusion zone, all marine works should stop immediately and remain idle for 30 minutes, or until the exclusion zone is free from marine mammals.

6.3.7.2 The experienced marine mammal observer should be well trained to detect marine mammals. Binoculars should be used to search the exclusion zone from an elevated platform with unobstructed visibility. The observer should also be independent from the project proponent and has the power to call-off construction activities.

6.3.7.3 In addition, as marine mammals cannot be effectively monitored within the proposed monitored exclusion zone at night, or during adverse weather conditions (i.e. Beaufort 5 or above, visibility of 300 meters or below), marine works should be avoided under weather conditions with low visibility.

6.3.8 Marine Mammal Watching Plan (MMWP)

6.3.8.1 Upon the completion of silt curtain installation / re-installation / relocation, the marine works would be conducted within an enclosed environment within the silt curtain. Subsequently, the plan would include Visual Inspectrion of the Waters Surrounded by Silt Curtains (Section 2.1, MMWP) and Regular Inspection of the Deployed Silt Curtain (Section 2.1, MMWP) inspection under Marine Mammal Watching Plan (MMWP) would be implemented (where applicable, Marine Mammal Exclusion Zone shall be conducted at the meantime). Special attention would be paid to Phase 2 (reclamation) where the floating type still curtain would be opened occasionally for vessel access, leaving a temporary 50 m opening. An action plan should be devised to cope with any unpredicted incidents such as the case when marine mammals are found within the waters surrounded by the silt curtains.

6.3.9 Assessment and Evaluation of Monitoring Results

6.3.9.1 A final marine mammal monitoring report should be submitted to AFCD for comments upon completion of the monitoring survey. The report should contain a summary of the survey findings during the entire monitoring programme, and assessment on the effectiveness of the mitigation measures implemented.

6.3.9.2 Evaluation of results should take natural fluctuations and accidental human-induced events (e.g. oil spill) into account. The monitoring results between the EIA study, AFCD�s long term marine mammal monitoring programme, and the construction phase, should be compared. Any significant difference should be identified and evaluated.

6.4 Coral Monitoring Programme

6.4.1 Introduction

6.4.1.1 A coral monitoring programme is recommended to verify the predicted impacts, and examine whether the mitigation measures recommended in the EIA report have been effectively implemented to protect the corals along the shore of Shek Kwu Chau from negative impacts from construction activities.

6.4.2 Coral Monitoring Survey

6.4.2.1 The coral monitoring programme should comprise 3 phases: pre-construction phase, construction phase, and operation phase (one year after the completion of construction works).

6.4.2.2 To monitor the health condition of corals during different phases, corals located within areas likely to be affected by the Project, and corals located at control sites (areas unlikely to be affected by the Project) should be chosen, in order to identify any adverse indirect impact from the marine works. The size, percentage cover and health condition of corals (i.e. any sign of abnormal appearance, such as layer of mucus, bleaching, partial mortality etc.) at representative transects should be recorded during each monitoring.

6.4.2.3 All monitoring should be led by suitably qualified persons with recognizable experience in coral monitoring survey. The survey methodology should remain the same during different phases, in order to allow direct comparison of coral monitoring results among different phases.

6.4.2.4 The methodology for coral monitoring programme should be consulted with the Agriculture, Fisheries and Conservation Department (AFCD) before the commencement of the monitoring programme. A more detailed coral monitoring plan, including which coral species and colonies to be monitored, methodology, monitoring frequency, and Event and Action Plan for coral monitoring should be submitted upon approval of this Project, prior to commencement of construction works.

Coral Survey (Donor site)

6.4.2.5 Since the visibility at SKC was very low (less than 0.5 m most of the time). An active search survey shall be conducted at the donor site at SKC as part of the detailed coral survey to locate all translocatable coral colonies.

6.4.2.6 The location of any corals shall be identified to species level as far as practicable and their locations were recorded. A specific code was assigned to each recorded coral colony.

6.4.2.7 The results shall be presented as a map showing the estimated locations of all coral colonies within the survey areas. The total number of coral colonies, their sizes and species shall be provided. The health condition (including percentage cover of bleaching, mortality, the degree of sedimentation) of the corals shall also be recorded and the feasibility of translocation of corals of conservation importance should be assessed.

6.4.2.8 Coral colonies (i.e. those attached to movable boulders with diameter <50 cm, in good health condition, and feasible for translocation) proposed to undertake translocation should be identified and mapped during the survey.

6.4.2.9 Upon completion of the surveys, the requirement for translocation and the required dimensions of the recipient site were identified. Based on the results of the donor site, all corals attached to movable boulders with diameter <50 cm would be considered feasible for translocation.

Coral Survey (Potential Recipient Sites)

6.4.2.10Spot-check dive surveys covering the potential recipient sites shall be conducted. The surveys are to check the presence of coral species similar to the donor site and the presence of suitable substratum to allow the translocated boulders/rocks to be permanently stabilized. The spot-check dive surveys required suitably trained and qualified SCUBA divers and marine ecologists swimming in a search pattern, at random depths within the spot-check dive area. Subtidal substrata (hard substratum seabed) within the proposed spot-check dive area should be surveyed for the presence of coral communities. Target species parameters including estimated number of species, coral cover, partial mortality and the presence of any rare corals will also be recorded during the spot-check dive. The divers also paid attention to the presence of non-typical reef structures, unusual coral species associations, unique or peculiar assemblages of the local reef formations, and reefs that are almost completely dominated by one particular species. Data should be recorded during the dives on water proof paper in preparation for a later consolidation and analysis.

6.4.2.11During the spot-check dive, the general environmental conditions of the potential recipient site should also observe (e.g. presence of healthy coral community with similar coral species as the donor site, presence of suitable substratum to allow the translocated boulders/rocks to be permanently stabilized, sufficient space to receive the newly translocated coral colonies, etc.). If the preliminary survey findings reveal that the potential recipient site is not suitable, alternative recipient site(s) should be searched.

6.4.3 Post-translocation Coral Monitoring Survey

6.4.3.1 Following coral translocation in the recipient site, the trans-located coral colonies as well as the tagged natural coral colonies at the recipient site will be monitored quarterly for one year (i.e. a total of four post-translocation monitoring). Monitoring will record the following parameters; the size, presence, survival, health conditions (percentage of mortality/bleaching) and percentage of sediment of each trans-located coral colony and each tagged natural colony. The general environmental conditions including weather, sea, and tidal conditions of the coral recipient site will also be monitored.

6.4.3.2 Photographic records of the trans-located and natural coral colonies will be taken as far as possible maintaining the same aspect and orientation as photographs taken for the pre-translocation surveys. All the tags for marking the trans-located and natural coral colonies will be removed / retrieved once the monitoring programme is completed.

6.4.3.3 If observations of any die-off / abnormal conditions of the translocated corals are made during the post-translocation monitoring, the ET should inform the Contractor, Independent Environmental Checker (IEC) and AFCD, and liaise with AFCD to investigate any mitigation measures needed.

6.4.3.4 Post-translocation monitoring results will be evaluated against Action and Limit Levels. Evaluation will be based on recorded changes in percentage of partial mortality of the corals. Action and Limit Levels are defined in Table 6.1. If defined Action Level or Limit Level for coral monitoring is exceeded, the actions as set out in Table 6.2 will be implemented.

6.4.3.5 Translocated coral colonies and the tagged natural coral colonies at the recipient site will be monitored quarterly for one year.

6.4.3.6 The results of the post-translocation monitoring surveys should be reviewed with reference to findings of the baseline survey and the data from original colonies at the recipient site. Further monitoring of the translocated coral colonies during Construction Phase is not proposed.

6.4.3.7 Findings from Post-Translocation Monitoring will be presented in the Monitoring Results Section under monthly EM&A Report of the respective reporting month and submitted to EPD and AFCD after completion of each quarterly survey.

Table 6.1 Action and Limit Levels for Post-Translocation Coral Monitoring

Parameter	Action Level Definition	Limit Level Definition
Mortality	If during Impact Monitoring a 15% increase in the percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that are not recorded on the original corals at the receptor site, then the Action Level is exceeded.	If during Impact Monitoring a 25% increase in the percentage of partial mortality on the corals occurs at more than 20% of the translocated coral colonies that are not recorded on the original corals at the receptor site, then the Limit Level is exceeded.

Note: If the defined Action Level or Limit Level for coral monitoring as listed in Table 6.1 is exceeded, the actions as set out in Table 6.2 will be implemented.

11 SITE ENVIRONMENTAL AUDIT & ENVIRONMENTAL COMPLAINTS

11.1 Site Inspection

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

11.1.2 The ET Leader should be responsible for formulating the environmental site inspection, the deficiency and action reporting system, and for carrying out the site inspection works. He / she should submit a proposal for site inspection and deficiency and action reporting procedures to the Contractor for agreement, and to the SO for approval. The ET�s proposal for rectification would be made known to the IEC.

11.1.3 Regular site inspections should be carried out at least once per week. The areas of inspection should not be limited to the environmental situation, pollution control and mitigation measures within the site, the site inspections should also review the environmental situation outside the works area which is likely to be affected, directly or indirectly, by the site activities. The ET Leader should make reference to the following information in conducting the inspection:-

� The EIA and EM&A recommendations on environmental protection and pollution control mitigation measures (including e.g. dust control measures and good site practice measures for ecological impact);

� Ongoing results of the EM&A programme;

� Work progress and programme;

� Individual work methodology proposals (which shall include proposal on associated pollution control measures);

� Contract specifications on environmental protection;

� Relevant environmental protection and pollution control laws; and

� Previous site inspection results undertaken by the ET and others.

11.1.4 The Contractor should keep the ET Leader updated with all relevant information on the construction contract necessary for him / her to carry out the site inspections. Inspection results and associated recommendations for improvements to the environmental protection and pollution control works should be submitted to the IEC and the Contractor within 24 hours for reference and for taking immediate action. The Contractor should follow the procedures and time-frame as stipulated in the deficiency and action reporting system formulated by the ET Leader to report on any remedial measures subsequent to the site inspections.

11.1.5 The ET should also carry out ad hoc site inspections if significant environmental problems are identified. Inspections may also be required subsequent to receipt of environmental complaint, or as part of the investigation work, as specified in the Action Plan for environmental monitoring and audit.

11.1.6 As per the Further Environmental Permit (FEP) requirements under Clause 2.21A, when carrying out the dredging works, the ET shall conduct daily site audit and monitoring. The following mitigation measures shall be strictly followed. As per the FEP Clause 2.18, dredging shall only be carried out by closed grab dredger(s), each with grab size of not more than 2m3. For area between 16m and 50m away from the nearest non-translocatable coral community, the maximum daily dredging rate shall not exceed 60 m3; for area between 50m and 100m away from the nearest non-translocatable coral community, the maximum daily dredging rate shall not exceed 380 m3. The dredging rate shall also refer to the approved Supporting Document for Reviewing Dredging Rate and Filling Rate in which combinations of on-site construction works and arragment of deploying silt curtain for coral protection would be taken into consideration for adjusting the dredging rate. Each grab shall be enclosed by silt curtain. No dredging shall be carried out within 16m to the nearest non-translocatable coral colony/ colonies. As per Environmental Impact Assessment Report Section 5b.7.3.29, daily site audit including on-ste monitoring by the ET is recommended during the dredging for anti-scouring layer protection for checking the compliance with the permitted number of grab to be performed per hour by the dredging contractor. All barges for transporting dredged/ waste materials shall be fitted with tight bottom seals to prevent leakage of materials during loading and transportation. If any of these measures are not complied with, ET shall give instructions to the Contractor to stop the Works and perform remedial actions.

11.2 Compliance with Legal and Contractual Requirements

11.2.1 There are contractual environmental protection and pollution control requirements as well as environmental protection and pollution control laws in Hong Kong with which construction activities must comply.

11.2.2 In order to ensure that the works are undertaken in compliance with the contractual requirements on environmental aspects, all works method statements submitted by the Contractor to the SO for approval should be sent to the ET Leader for vetting to see whether sufficient environmental protection and pollution control measures have been included. The implementation schedule of mitigation measures is summarised in Appendix 11.1

11.2.3 The ET Leader should also review the progress and programme of the works to check that relevant environmental laws have not been violated, and that any foreseeable potential for violating laws could be prevented.

11.2.4 The Contractor should regularly copy relevant documents to the ET Leader so that works checking could be carried out. The document should at least include the updated Works Progress Reports, updated Works Programme, any application letters for different licences / permits under the environmental protection laws, and copies of all valid licences/ permits. The site diary should also be available for the ET Leader's inspection upon his / her request.

11.2.5 After reviewing the documentation, the ET Leader should advise the IEC and the Contractor of any non-compliance with contractual and legislative requirements on environmental protection and pollution control for them to take follow-up actions. If the ET Leader's review concludes that the current status on licence / permit application and any environmental protection and pollution control preparation works may result in potential violation of environmental protection and pollution control requirements, he / she should also advise the Contractor and the SO accordingly.

11.2.6 Upon receipt of the advice, the Contractor should undertake immediate action to correct the situation. The SO should follow up to ensure that appropriate action has been taken to satisfy contractual and legal requirements.

11.3 Environmental Complaint

11.3.1 Complaints should be referred to the ET Leader for action. The ET Leader should undertake the following procedures upon receipt of any complaint:

� log complaint and date of receipt onto the complaint database and inform the IEC immediately;

� investigate the complaint to determine its validity, and assess whether the source of the problem is due to works activities;

� identify mitigation measures in consultation with the IEC if a complaint is valid and due to works;

� advise the Contractor if mitigation measures are required;

� review the Contractor's response on the identified mitigation measure(s) and the updated situation;

� if the complaint is transferred from the EPD, submit interim report to the EPD on status of the complaint investigation and follow-up action within the time frame assigned by the EPD;

� undertake additional monitoring and audit to verify the situation if necessary, and review that circumstances leading to the complaint do not recur;

� report investigation results and subsequent actions to complainant (if the source of complaint is EPD, the results should be reported within the timeframe assigned by the EPD); and

� record the complaint, investigation, the subsequent actions and the results in the monthly EM&A reports.
