Report

1 Introduction

1.1.1.1 Currently 117 public piers in Hong Kong are built, maintained and managed by the Government. Whilst the Government has carried out regular inspections and maintenance for public piers to ensure their structural integrity, some public piers at remote areas are in service for many years suffering from aging problem, or cannot cope with the current needs/ usages, such as:

· unsatisfactory boarding condition of small or primitive piers leading to potential safety concerns to passengers especially for kids and elderly;

· inadequate water depth for larger vessels to berth especially during low tide;

· limited berthing space or narrow accesses which cannot cope with the fluctuating utilization rate during festive times or weekends; and

· aged pier structures with a need for improvement works.

1.1.1.2 In 2017 Policy Address, the Government committed to improve a number of remote public piers to facilitate public access to outing destinations and natural heritage such as Hakka village at Lai Chi Wo and Hong Kong UNESCO Global Geopark. To take forward the policy initiative, the Government has launched the Pier Improvement Programme (PIP) for the implementation of improvement works for piers at remote areas.

1.1.1.3 A Committee on Piers spearheaded by the Development Bureau, comprising members of relevant bureaux and departments was set up to examine the requests received by different departments concerning improvement suggestions for public piers in the New Territories and outlying islands and set priority for pier improvement items under the PIP taking into account a host of factors including structural and public safety concerns. The Committee has recommended implementing a list of 10 proposed pier improvement items under the first implementation phase of the PIP. Lai Chi Wo Pier is one of the recommended proposed pier items.

1.1.1.4 The Lai Chi Wo Pier is located along the coastal area of Northeast New Territories. It is located within the Hong Kong UNESCO Global Geopark (Double Haven Geo-Area), Yan Chau Tong Marine Park and partly within Plover Cove Country Park. Designated in 1979 due to the presence of seagrass Zostera japonica, Lai Chi Wo Beach SSSI is located at about 150m to the south of the existing pier. A historical building at the nearby Lai Chi Wo Village, namely Hip Tin Temple & Hok Shan Monastery, is a Grade 3 historic building and Lai Chi Wo Site of Archaeological Interest is also located nearby. The pier was constructed in the 1960s and is primitive and aging. It is a solid concrete finger pier of about 64m long and 2.5m wide. The pier level is about +3metres above Principal Datum (mPD), at low tide, the water depth is about 0.5m.

1.1.1.5 Lai Chi Wo Pier is the main access for the public to Lai Chi Wo village as the nearest land access is from Wu Kau Teng which is about two hours of walk by trail. There is currently Kaito-ferry service operated between Ma Liu Shui Ferry Pier and Lai Chi Wo Pier on Sundays and public holidays. Lai Chi Wo Pier has only one landing steps, at low tides, there is inadequate water depth for the vessels to berth.

1.1.1.6 Although the Government departments carry out regular inspection and maintenance, the existing Lai Chi Wo Pier has been in service for many years suffering from aging problem and cannot cope with the current growing needs. In addition, there have been repeated requests from the Sha Tau Kok District Rural Committee members, North District Council members and Village Representatives (VRs) to improve Lai Chi Wo Pier to facilitate public access to Lai Chi Wo. Therefore, Pier Improvement at Lai Chi Wo (the Project) is being proposed and taken forward.

1.1.1.7 The overall objective of this Project is to conduct environmental impact assessment (EIA) study and preliminary engineering studies before proceeding with the detailed design and construction of the Project.

1.1.1.8 Upon completion, the Project would have a width of 6m to 8m increased to 15m at the pier head and a length of 155m with the following facilities/features such as:

· Deeper berths;

· Covered sitting / waiting area; and

· Floating pontoon together with downstand wave walls at pier head for facilitating barrier-free access/to vessels;

1.1.1.9 In June 2018, Civil Engineering and Development Department (CEDD) commissioned Ove Arup and Partners Hong Kong Limited (Arup) to provide consultancy services for Agreement No. CE2/2018 (CE) “Study for Pier Improvement at Lai Chi Wo and Tung Ping Chau – Investigation” (the Study). This consultancy includes, among others, compilation and submission of an EIA Report to fulfil the relevant legislative requirements. The Study is separated into two parts – one is Pier Improvement at Lai Chi Wo and the other is Pier Improvement at Tung Ping Chau. This EIA report covers the environmental impact assessment of the Pier Improvement at Lai Chi Wo under the EIA Ordinance (EIAO) (Cap. 499). The EIA Report for Tung Ping Chau is separately submitted under the EIAO.

4 Environmental Submission

4.1 Introduction

4.1.1.1 The Contractor shall prepare an Environmental Management Plan (EMP) (including a Waste Management Plan, WMP), a Construction Method Statement prior to the commencement of construction works and obtain approval from ER and IEC and other relevant authorities to encompass the recommended environmental protection / mitigation measures with respect to their latest construction methodology and programme.

4.2 Environmental Management Plan

4.2.1.1 A systematic EMP shall be set up by the Contractor to ensure effective implementation of the mitigation measures, monitoring and remedial requirements presented in the EIA, EM&A and Environmental Mitigation Implementation Schedule (EMIS) (See Appendix 4.1). The ER and the IEC will audit the implementation status against the EMP and advise the necessary remedial actions required. These remedial actions shall be enforced by the ER through contractual means.

4.2.1.2 The EMP will require the Contractor (together with its sub-contractors) to define in detail how to implement the recommended mitigation measures in order to achieve the environmental performance defined in the Hong Kong environmental legislation and the EIA documentation.

4.2.1.3 The review of on-site environmental performance shall be undertaken by ER and IEC through a systematic checklist and audit once the construction works commences. The environmental performance review programme comprises a regular assessment on the effectiveness of the EMP. Reference should be made to ETWB TC 19 / 2005 “Environmental Management on Construction Sites” or its latest versions, and any other relevant Technical Circulars.

4.3 Waste Management Plan

4.3.1.1 As part of the EMP, the Contractor shall include WMP for the construction of the Project and prior to the commencement of construction works submit it to the ER and IEC for approval. Where waste generation is unavoidable, the opportunities for recycling or reusing should be maximised. If wastes cannot be recycled, recommendations for appropriate disposal routes should be provided in the WMP. A method statement for stockpiling and transportation of the excavated materials and other construction wastes should also be included in the WMP and be approved before the commencement of construction works. All mitigation measures arising from the approved WMP shall be fully implemented.

4.3.1.2 For the purpose of enhancing the management of Construction and Demolition (C&D) materials including rock, and minimising its generation at source, construction works would be undertaken in accordance with the Section 4.1.3 of Chapter 4 in the Project Administration Handbook for Civil Engineering Works (PAH).

4.4 Construction Method Statement

4.4.1.1 In case the Contractor would like to adopt alternative construction methods or implementation schedules, it is required to submit details of methodology and equipment to the ER for approval before the work commences. Any changes in construction method shall be reflected in a revised EMP or the Contractor will be required to demonstrate the manner in which the existing EMP should accommodate the proposed changes. The Contractor may need to apply for a Variation of Environmental Permit (VEP) from EPD before commencement of any construction activities.

5 Air Quality

5.1 Introduction

5.1.1.1 The EIA has considered the potential air quality impacts associated with the Project. As adverse fugitive dust emission or air quality impacts during construction and operational phases are not anticipated, mitigation measures and monitoring are not required. Nevertheless, regular site environmental audits are recommended to check the implementation of good site practices.

5.2 Mitigation Measures

5.2.1 Construction Phase

5.2.1.1 During construction phase, mitigation measures are not required. However, good site management practices as stipulated in Air Pollution (Construction Dust) Regulation (e.g. regular watering) shall be implemented to minimise potential construction dust impacts. The following dust suppression measures/practices should be incorporated by the Contractor to control the dust nuisance throughout the construction phase:

· Spray water regularly as required at the surrounding pier area, access and working barges;

· Cover or shelter any stockpile of dusty materials on working barges; and

· Cover any dusty load on the barge by impervious sheeting on the construction barges before they leave the site.

5.2.1.2 To minimise air quality impact from fuel combustion, PME used in the construction site should be registered under Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation with the NRMM label displayed at a conspicuous position of the registered item. In addition, routing of barges used for delivery of goods should be as far away from the identified ASRs as practicable.

5.2.1.3 The Contractor is also advised to minimise the number of boat trips as far as practicable by appropriate planning to maximise the utilisation of each trip traveling to and from the nearest pier in other district and the Project site.

5.2.1.4 All the recommended good practices are summarised in the Environmental Mitigation Implementation Schedule (EMIS) given in Appendix 4.1.

5.2.2 Operational Phase

5.2.2.1 Adverse air quality impacts are not anticipated during operational phase, and thus mitigation measures are not required.

5.3 Environmental Monitoring and Site Audit Requirements

5.3.1 Construction Phase

5.3.1.1 Good practices have been recommended in the EIA Report. The Contractor shall be responsible for the design and implementation of these good practices. Regular audits and site inspection at least once per week should be carried out during the construction phase by the Contractor and ET to ensure that the recommended good practices have been properly implemented by the Contractor.

5.3.2 Operational Phase

5.3.2.1 Adverse air quality impacts during operational phase are not anticipated. Hence, monitoring and audit is not required .

6 Noise

6.1 Introduction

6.1.1.1 The EIA Report has considered the potential noise impacts associated with the Project. Noise from the use of powered mechanical equipment (PME) would be the major potential noise impacts during the construction phase. Other than the existing Plover Cove Country Park, there are no other Noise Sensitive Receivers (NSRs) within the 300m assessment area. Construction noise monitoring is not necessary. Nevertheless, it is also recommended that regular site inspections should be undertaken to inspect the construction activities and works area in order to ensure the recommended mitigation measures are properly implemented to minimise the noise disturbance to the existing Country Park environment.

6.2 Mitigation Measures

6.2.1 Construction Phase

6.2.1.1 Adverse construction noise impacts are not anticipated during the construction phase and hence mitigation measures are not required. Nevertheless, the Contractor shall implement good site management practices to avoid the potential construction noise impact. The following good site management practices should be incorporated by the Contractor to minimise the noise disturbance to the Country Park environment during the construction phase:

· Good site practices to limit noise emission at the source;

· Use of Quality Powered Mechanical Equipment (QPME);

· Use of temporary noise barriers to screen noise from relatively static PME; and

· Alternative use of plant items within one worksite, wherever practicable.

6.2.1.2 The above recommended practices would need to be implemented in work sites as good practices where appropriate. “Recommended Pollution Control Clauses for Construction Contracts” promulgated by EPD will be added to the Contract for future contractors to follow. Detailed description of these good site management practices is given in the following sections.

Good Site Management Practices

6.2.1.3 Good site practice and noise management techniques could considerably reduce the noise impacts from construction site activities. The following measures should be practised during each phase of construction:

· only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction programme;

· machines and plant (such as crane and generator) that may be in intermittent use should be shut down between work periods or should be throttled down to a minimum;

· plant known to emit noise strongly in one direction, where possible, be orientated so that the noise is directed away from nearby NSRs;

· silencers or mufflers on construction equipment should be properly fitted and maintained during construction works;

· mobile plant should be sited as far away from NSRs as possible and practicable; and

· material stockpiles, site office and other structures should be effectively utilised, where practicable, to screen noise from on-site construction activities.

6.2.1.4 The environmental noise climate would certainly be improved with these good site management practices.

Use of Quality Powered Mechanical Equipment (QPME)

6.2.1.5 The use of quiet plant associated with the construction works should make reference to the PME listed in the TM or the QPME/ other commonly used PME listed in EPD web pages as far as possible which includes the SWLs for specific quiet PME. It is generally known (supported by field measurement) that particular models of construction equipment are quieter than standard types given in the TM-GW. Whilst it is generally considered too restrictive to specify that the Contractor has to use specific models or items of plant, it is reasonable and practicable to set plant noise performance specifications for specific PME so that some flexibility in selection of plant is allowed. A pragmatic approach would be to request that the Contractor independently verifies the noise level of the plant proposed to be used and demonstrates through furnishing of these results, that the plant proposed to be used on the site meets the requirements.

Use of Temporary Noise Barriers to Screen Noise from Relatively Static PME

6.2.1.6 Movable temporary noise barriers will be used for some PME (e.g. breaker, mobile crane) where practicable. It is anticipated that suitably designed barriers could achieve at least 5dB(A) reduction for movable plant. Acoustic mat would be used for other plant items such as piling rig and a 5 dB(A) noise reduction is anticipated.

Alternative Use of Plant Items within One Worksite

6.2.1.7 In practice, some plant items will operate sequentially within the same work site, and certain reduction of the predicted noise impacts could be achieved. However, any additional control on the sequence of plant will impose a restrictive constraint to the Contractor on the operation and planning of plant items, and the implementation of the requirement would be difficult to be monitored.

6.2.1.8 All the recommended good practices are summarised in the Environmental Mitigation Implementation Schedule (EMIS) given in Appendix 4.1.

6.2.2 Operational Phase

6.2.2.1 Adverse noise impacts are not anticipated during operational phase, and thus mitigation measures are not required.

6.3 Environmental Monitoring and Site Audit Requirements

6.3.1 Construction Phase

6.3.1.1 Good site management practices have been recommended in the EIA Report. The Contractor shall be responsible for the design and implementation of these good site management practices. Regular audits and site inspection at least once per week should be carried out during the construction phase by the Contractor and ET to ensure that the recommended mitigation measures have been properly implemented by the Contractor.

6.3.2 Operational Phase

6.3.2.1 Adverse noise impacts during operational phase are not anticipated. Hence, monitoring and audit is not required.

7 Water Quality

7.1 Introduction

7.1.1.1 The EIA Report has assessed the potential water quality impacts associated with the Project. According to the EIA Report, the water quality impact could be minimised with the implementation of mitigation measures. The water quality monitoring programme as discussed below could ensure the implementation of the recommended mitigation measures and provide continue improvements to the environmental conditions.

7.2 Mitigation Measures

7.2.1 Construction Phase

7.2.1.1 The EIA Report has recommended mitigation measures such as installation of silt curtain prior to the commencement of construction works. Silt curtains should only be removed after the completion of the marine-based site investigation and construction works. All the recommended good practices are summarised in the EMIS in Appendix 4.1.

7.2.2 Operational Phase

7.2.2.1 Adverse water quality impacts are not anticipated during operational phase. Mitigation measures are therefore not required.

7.3 Water Quality Monitoring Parameters

7.3.1.1 The monitoring shall be established by measuring the dissolved oxygen (DO), dissolved oxygen saturation (DO%), temperature, turbidity, salinity, pH and suspended solids (SS) in the water body at all designated locations as specified in Section 7.6.

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

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

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

7.4 In-situ Monitoring Equipment

7.4.1 Dissolved Oxygen Equipment

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

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

· A temperature of 0 – 45 degree Celsius.

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

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

7.4.2 Turbidity Measuring Equipment

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

7.4.3 Salinity Measuring Equipment

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

7.4.4 pH Measuring Equipment

7.4.4.1 A portable pH meter of measuring a pH range between 0.0 and 14.0 shall be provided under the specified conditions (for example Orion Model 250A or an approved similar equipment).

7.4.5 Positioning Equipment

7.4.5.1 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 instrument of similar accuracy, should be provided and used during marine water monitoring to ensure the monitoring vessel is at the correct location before taking measurements.

7.4.6 Water Depth Detector

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

7.4.7 Water Sampling Equipment

7.4.7.1 Proper water samplers are required for monitoring. It should comprise a transparent PVC cylinder, with a capacity of not less than 2 litres, which can be effectively sealed with latex cups at both ends. The sampler should have a positive latching system to keep it open to 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).

7.4.8 Sample Containers and Storage

7.4.8.1 Water samples for SS should be stored in high density polythene bottles with no preservative added, while those for fungicides and insecticides should be stored in amber glass bottles with no preservative added, packed in ice (cooled to 4°C without being frozen) and shipment to the testing laboratory. The samples shall be delivered to the laboratory of collection and be analysed as soon as possible after collection.

7.4.9 Calibration of In-Situ Instruments

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

7.4.10 Back-up Equipment and Vessels

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

7.4.10.2 The water quality monitoring will involve four monitoring stations during the construction phase, and measurements should be conducted within the prescribed tidal conditions in order to ensure the measurement / samples are representative. A multi-probe monitoring equipment set integrated with water sampler(s) is highly recommended to improve the monitoring efficiency. Depending on the actual operation, more than one field survey vessels might be required simultaneously to ensure the monitoring are conducted within the acceptable monitoring period. The ET shall also consider the use of unattended automatic sampling / monitoring devices at fixed stations where monitoring is required throughout the construction period. The use of such unattended automatic devices, however, shall be subject to the approval of the ER, IEC and EPD.

7.5 Laboratory Measurement/Analysis

7.5.1.1 At least 3 replicate samples from each independent sampling event are required for the SS measurement which shall be carried out in a HOKLAS or international accredited laboratory. Where water depth is allowed, sampling should be conducted at three water depths which are 1m below water surface, mid-depth, and 1m above the sea bed. If the sampling water depth is less than 6m, the mid-depth may be omitted. If the water depth is less than 3m, only the mid-depth may be monitored. Sufficient water samples shall be collected at the monitoring stations for carrying out the laboratory measurement and analysis. The laboratory determination work shall start within 24 hours after the collection of water samples. The analysis for suspended solids is presented in Table 7.1.

7.7 Baseline Monitoring

7.7.1.1 Baseline conditions for water quality shall be established and agreed with EPD prior to the commencement of construction works. The baseline conditions shall include the water quality parameters specified in Section 7.3. The proposed water quality monitoring schedule shall be submitted to EPD by the ET at least 2 weeks before the first day of the monitoring month. The baseline monitoring shall be conducted for at least 4 weeks prior to the commencement of construction works with a frequency of 3 days in a week, at mid-flood and mid-ebb tides. The interval between two sets of monitoring shall not be less than 36 hours. EPD shall also be notified immediately for any changes in schedule.

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

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

7.7.1.4 Table 7.3 summarises the proposed water quality monitoring programme for baseline monitoring.

7.9 Action and Limit Levels

7.9.1.1 The Action and Limit levels for water quality of all water monitoring stations during the construction phase are defined in Table 7.5 below.

Table 7.5 Action and Limit levels for water quality of all water monitoring stations during the construction phase

Parameters	Action Level	Limit Level
DO in mg/L (Surface, Middle & Bottom)	Surface and Middle 5 percentile of baseline data.^[¹^] Bottom 5 percentile of baseline data. ^[¹^]	Surface and Middle 4 mg/L except 5 mg/L for fish culture zone; or 1 percentile of baseline data.^[¹^] Bottom 2 mg/L or 1 percentile of baseline data. ^[¹^]
SS in mg/L (depth-averaged) ^[3]	95 percentile of baseline data / 120% of upstream control stations’ results ^[2]	99 percentile of baseline data / 130% of upstream control stations’ results ^[2]
Turbidity in NTU (depth-averaged) ^[3]	95 percentile of baseline data / 120% of upstream control stations’ results ^[2]	99 percentile of baseline data / 130% of upstream control stations’ results ^[2]

Notes:

[1] For DO, non-compliance occurs when monitoring results is lower than the limits.

[2] For SS and turbidity, non-compliance occurs when monitoring results is larger than the limits.

[3] "Depth-averaged" is calculated by taking the arithmetic means of readings of all three depths.

8 Waste Management

8.1 Introduction

8.1.1.1 The quantity of waste generated during the construction phase have been estimated in the EIA Report. Measures including the opportunity for on-site sorting, reusing excavated materials etc., are devised in the construction methodology to minimise the surplus materials to be disposed of off-site. Chemical waste should be collected by licensed chemical waste collectors for proper disposal.

8.2 Mitigation Measures

8.2.1 Construction Phase

8.2.1.1 Waste will be handled in accordance with the relevant legislation and guidelines and with the implementation of the proposed mitigation measures, no adverse environmental impacts from waste management are anticipated. EM&A is required for waste management during the construction phase only and the effective management of waste arising during the construction phase will be monitored through the site audit programme. The aims of the waste audit are:

· to ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner; and

· to encourage the reuse and recycling of material.

8.2.1.2 A trip-ticket system in accordance with DEVB TC(W) No. 6/2010 Trip Ticket System for Disposal of Construction and Demolition Materials should be operated to monitor all movements of inert C&D materials for disposal at public fill bank and chemical wastes which will be collected by licensed chemical waste collectors to licensed facilities for final treatment and disposal. Marine sediments should be disposed of at dedicated marine disposal sites. Recommendations have been made in the EIA Report to ensure proper treatment and proper disposal of these wastes and summarised in the Environmental Mitigation Implementation Schedule (EMIS) Appendix 4.1.

8.2.2 Operational Phase

8.2.2.1 As discussed in the EIA report, general refuse is anticipated to be the major waste type generated from the visitors of the pier. Sufficient number of trash bins and recycling bins have already been provided for the collection of general refuse generated by visitors and pier users along the existing footpath to Lai Chi Wo. No bin will be provided as no general refuse is anticipated by the Project during the operational phase. Nevertheless, recycling containers are recommended to be provided at suitable locations to encourage recycling of waste such as aluminium cans and plastics.

8.3 Environmental Monitoring and Site Audit Requirements

8.3.1 Construction Phase

8.3.1.1 The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant licenses/ permits for waste disposal. The ET shall ensure that the Contractor has obtained from the appropriate authorities the necessary waste disposal permits or licenses including:

· Chemical Waste Producer Registration under the Waste Disposal Ordinance (Cap. 354);

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

· Water Pollution Control Ordinance License under the Water Pollution Control Ordinance (Cap. 358); and

· Marine Dumping Permit under Dumping at Sea Ordinance (Cap. 466).

8.3.1.2 The Contractor shall refer to EPD’s Guidance Notes for License Application when applying for the license/permit under Waste Disposal Ordinance, Water Pollution Control Ordinance and Dumping at Sea Ordinance. The ET shall refer to these Guidance Notes for auditing purposes.

8.3.1.3 Regular audits and site inspections should be carried out during construction phase by the ET to ensure that the recommended good site practices and other mitigation measures recommended in the EIA Report and in Appendix 4.1 are properly implemented by the Contractor. The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.

8.3.1.4 The requirements of the environmental audit programme are set out in Section 14 of this Manual. The audit programme will verify the implementation status and evaluate the effectiveness of the mitigation measures.

8.3.2 Operational Phase

8.3.2.1 As it is anticipated that there would not be any insurmountable impacts during the operational phase, monitoring and audit requirements are not required.

9 Land Contamination

9.1 Introduction

9.1.1.1 The EIA Report has stated the land contamination issues associated with the Project. As outlined in Section 7 of the EIA Report, based on the desktop review findings of selected aerial photos, the information collected during site survey as well as EPD and Fire Services Department (FSD), no potential land contamination issue is identified in the Project Site. In addition, potentially land contaminating activities or land use under the Project are not anticipated.

9.2 Mitigation Measures

9.2.1.1 Potential land contamination issue within the Project Site were not identified and hence further site investigation or mitigation measures are not required.

9.3 Environmental Monitoring and Site Audit Requirements

9.3.1 Construction Phase

9.3.1.1 Environmental monitoring and site audit are not required for construction phase.

9.3.2 Operational Phase

9.3.2.1 Environmental monitoring and site audit are not required for operational phase.

10 Ecology

10.1 Introduction

10.1.1.1 The EIA has evaluated the ecological consequences of the Project and recommended ecological mitigation measures to avoid, and minimise the impact arising from the Project.

10.2 Mitigation Measures

10.2.1 Avoidance

Terrestrial

10.2.1.1 Different locations for the construction works of the connecting walkway between the proposed LCW Pier and the existing footpath to Lai Chi Wo were explored, the present proposed location is more appropriate given the need to reserve spaces for the works and berthing. Although the area of the connecting walkway between the proposed LCW Pier and the existing footpath to Lai Chi Wo is mapped as woodland, tree loss will be avoided. Hence, no woodland loss is confirmed. Encroachment of other terrestrial recognised sites of conservation importance including Lai Chi Wo Special Area, Conservation Area, Ecologically Important Stream and Fung Shui Woodland have also been avoided.

Marine

10.2.1.2 Although the proposed works area is within the Yan Chau Tong Marine Park, important habitats such as mangrove and seagrass bed are totally avoided. Other recognised sites of conservation importance such as Lai Chi Wo Beach SSSI and the coral communities identified in Hong Kong Reef Check are also avoided.

10.2.2 Minimisation

Terrestrial

10.2.2.1 The connecting walkways have to be reconstructed between the temporary pier/ proposed LCW Pier and the existing footpath to Lai Chi Wo. The proposed works area for two connecting walkways has been limited (e.g. only 2m side on each side of both walkways would be occupied), the encroachment of Plover Cover Country Park has been minimized. Although a small part of connecting walkway is mapped as woodland, no trees will be affected, and no actual woodland loss will be occurred. Besides, only small and/or manual handling equipment shall be deployed to construct the walkways, in order to further minimize construction impacts to country park.

10.2.2.2 No glare will be occurred as there will be no night works during construction phase. During operational phase, additional lighting in the new pier head will be kept to minimal for safety purpose; so that the impacts to nocturnal life can be reduced.

Marine

10.2.2.3 Construction impacts to marine ecological resources have been largely avoided by adopting piled foundation to support the pier structures instead of open sea dredging and replaced by hard material to facilitate solid pier construction as pier improvement works. By adopting the piled foundation method, the seabed loss can be greatly reduced and water quality will not be affected significantly as there will be no dredging works of the seabed.

10.2.2.4 According to the water quality chapter, by adoption of the pile casing and silt curtain can further confine the sediment to prevent the release of muddy water to the adjacent sensitive receivers (e.g. mangrove, seagrass bed) as a result of foundation works. Water contaminated with slurry rock fragment should be stored in a barge and recycled for use again in the foundation works.

10.2.2.5 Wastewater coming from the grouting of piles shall be treated in sedimentation tank placed in a barge before discharging offsite with a valid discharge license under the Water Pollution Control Ordinance.

10.2.2.6 Emergency Spillage Plan should be established during the construction phase as a precautionary measure so that appropriate actions to prevent or reduce risks to sensitive receivers in the vicinity can be undertaken in the event of an accidental spillage.

10.2.2.7 A no-dumping policy is simply a policy prohibiting dumping of wastes, chemicals, oil, trash, plastic, or any other substance that would potentially be harmful to marine habitats. It is mandatory that an educational program of the no-dumping policy be made available to all construction-site personnel for all project-related works. The policy needs to be strictly enforced and there need to be stiff fines for infractions. Unscheduled, on-site audits will also generally be required.

10.2.3 Other Mitigation

Terrestrial

10.2.3.1 Since no significant impact to terrestrial habitats and associated wildlife is anticipated, no mitigation measure for terrestrial ecology is recommended. However, as a precautionary measure, inspection should be conducted to make sure no trees within the Plover Cove Country Park will be affected.

Marine

10.2.3.2 A pre-construction dive survey should be conducted to verify the conditions of the small coral colonies on the existing LCW pier before any construction works. If it is found in the survey that those colonies have grown to a size suitable for translocation or other corals of higher conservation value have newly colonised on the pier, a translocation proposal might be needed.

10.2.3.3 The mitigation measures for water quality impacts have been stated in the section of water quality assessment. Besides silt curtains and casing to confine the sediment, good site practices for water quality in marine works should be strictly followed. As there were no corals within the pier improvement works except the existing pier head, deployment of silt curtains and outer casing will not encroach any coral colonies.

10.2.4 Enhancement Measures

10.2.4.1 As there will be a vertical above-seabed downstand wall and piles to support the new pier, the subtidal portion of many man-made structures could provide hard substrates for colonization of corals or other epibenthos. The submerged structures in the future new pier extension could also provide hard surface for colonization of marine sessile epibenthos. It is also known that by suitable design, the colonization of epibenthos would be faster and/or of higher abundance, and the ecological functions of epibenthic communities on the subtidal portions of these structures could be further enhanced.

10.2.4.2 It is proposed that the future design of the downstand wall and piles should take into account the enhancement of ecological functions. One of the approaches is to provide uneven surface or selected patterns on the future downstand wall and piles (either incorporating on the structures or installing additional panels/ tiles with such features). The enhanced surface could provide microhabitats for various marine organisms to colonise and grow, and develop into communities to provide feeding and hiding habitats for juveniles of marine fauna, and thereby effectively enhance biodiversity and ecosystem functions of the new man-made structures.

10.2.4.3 It is therefore recommended that during the detailed design of the pier improvement, a study should be conducted to explore and confirm the feasible enhancement measures to be adopted, to investigate the proper form of enhanced surface of the hard structures to be adopted for the above-seabed downstand wall and piles. The enhancement study report covering the recommendations of the proper form of design to be adopted, the detailed design and the implementation programme will be submitted for the approval of the authority before commencement of the works.

10.3 Environmental Monitoring and Site Audit Requirements

10.3.1.1 As a precautionary measure, inspection should be conducted to make sure no trees within the Plover Cove Country Park will be affected.

10.3.1.2 Given to the close proximity to some of the ecological sensitive habitats (i.e. mangrove, seagrass bed, coral community), water quality monitoring is recommended to be undertaken at the nearby waters prior to the commencement of the construction as well as during the construction phase. Baseline data should be obtained prior to the start of the construction. Regular monitoring should be carried out throughout the whole construction phase to ensure that the water quality complies with the established environmental standards as stated in water quality chapter.

10.3.1.3 Due to the importance and rarity of seagrass bed in Lai Chi Wo Beach SSSI, ecological monitoring of seagrass bed is recommended in the EIA report. The ecological EM&A programme during construction and operation will be implemented as set out in this manual. Three major components i.e. baseline survey, construction phase monitoring, and operational phase monitoring, shall be included.

10.3.1.4 The ecological monitoring and auditing will be conducted by a qualified ecologist who has a suitable background in ecology or botany as well as relevant experience, and to be approved by AFCD.

Baseline Survey

10.3.1.5 A baseline survey will be conducted for seagrass bed shown in Figure 8.3 of EIA report, before the commencement of any construction works. The extent of the seagrass bed, the coverage percentage and health conditions of seagrasses will be recorded.

Construction Phase EM&A

10.3.1.6 The seagrasses will be monitored weekly during the first two weeks of construction phase and start of piling works. If no exceedance of water quality due to the construction works will be recorded, the monitoring schedule would be changed to monthly till the construction works are finished. The extent of the seagrass bed, the coverage percentage and health conditions of seagrasses will be recorded.

10.3.1.7 The data from the water quality monitoring should be reviewed from time to time. If the water quality monitoring shows no attributable effects of the construction works, impacts to seagrass bed is not expected. If the water quality data indicate exceedances, the ET Leader should discuss with the Contractor the most appropriate method of reducing the water quality impacts. The mitigated methods should then be enacted on the next working day.

10.3.1.8 Ad-hoc inspection of seagrass bed is required if the water quality data indicate exceedances due to the construction works. If the Limit Level for water quality is exceeded, the ET Leader should inform all parties (Contractor, Project Proponent, EPD, AFCD and IEC) immediately. Should the Action Level for water quality is exceeded, the Contractor should follow the action plan stated in water quality chapter.

Operational Phase EM&A

10.3.1.9 During operational phase, the seagrass monitoring would be conducted during the first year of the operational phase. The monitoring schedule during the first three month would be monthly. After that, the monitoring schedule would be changed to semi-annually, i.e. once in dry season and once in wet season. The need of any further monitoring will be reviewed according to the monitoring results after the first year monitoring.

11 Fisheries

11.1 Introduction

11.1.1.1 Residual fisheries impacts would be the permanent loss of about 0.156 ha and of moderate production fishing ground in Lai Chi Wo. Given the small proportion in fishing grounds in Hong Kong waters and the small contribution on Hong Kong fisheries production, as well as the implementation of the mitigation measures for water quality, the residual impact is considered acceptable.

11.1.1.2 The EIA has considered avoidance and minimisation for the impacts arising from the Project.

11.2 Mitigation Measures

11.2.1 Consideration of Impact Avoidance

11.2.1.1 The waters around Lai Chi Wo is within the spawning ground and nursery area for commercial fisheries resources. Alternative sites for the LCW pier is considered not feasible, or else the pier will be located far away from the Lai Chi Wo Village. Nevertheless, there is no mariculture site within the proposed LCW Pier. The proposed pier is also not located in waters of high fisheries production or fish fry collection.

11.2.2 Consideration of Impact Minimisation

11.2.2.1 During the construction phase, the mitigation measures as detailed in water quality chapter should be implemented / adopted. The mitigation measures cover the potential water quality impacts from marine-based site investigation works, marine-based foundation works, above-water construction works, site run-off from general site operation, accidental spillage of chemicals and sewage from workforce. With the implementation of the mitigation measures for water quality, no adverse fisheries impact is anticipated and no additional mitigation measure is required.

11.2.2.2 No specific mitigation measures would be required for the operational phase of the Project.

11.3 Environmental Monitoring and Site Audit Requirements

11.3.1.1 Site inspections under water quality chapter during construction phase should be carried out to monitor any malpractice leading to deterioration of water quality of the surrounding which may in turn affect the fisheries resources (i.e. a monitoring and audit programme aims to ensure that the released suspended solids (SS) concentrations from the piling activities). As there are no anticipated adverse impacts during operational phase, monitoring and audit requirements are not required.

12 Landscape and Visual

12.1.1 Introduction

12.1.1.1 The EIA has recommended that EM&A for landscape and visual resources is undertaken during the design, construction and operational phases of the project. The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that any potential conflicts between the proposed landscape measures and any other works of the Project would be resolved at early as practical without affecting the implementation of the mitigation measures.

12.1.1.2 The proposed mitigation measures of landscape and visual impacts are summarised in Appendix 4.1. The construction phase mitigation measures will be adopted and audited from the commencement of construction throughout the entire construction period. Mitigation measures for the operational phase will be adopted during the detailed design and be built as part of the construction works so that they are in place on commissioning of the Project.

12.2 Mitigation Measures

12.2.1 Construction Phase

12.2.1.1 The landscape and visual mitigation measures to be incorporated in the design and construction phase, and relevant agencies for the measures are summarised in Table 12.1 and shown in Figure 12.1.

Table 12.1 Recommended Mitigation Measures in Construction Phase

ID	Mitigation Measures	Responsible Agent for Implementation of Mitigation Measures
CM1	Minimisation of Construction Area The footprint of the improved pier structure should be minimised as far as practicable to minimise the potential landscape and visual disturbance.	Project Proponent - CEDD (Via the Engineer)

Tree Preservation Strategy

12.2.1.2 For the Project, all associated construction activities will be limited to the site boundary and will not encroach upon the existing footpath, which lies under the tree crown, outside the site boundary. In addition, the pier improvement works mainly focuses on the pier structure in the sea and no works will be carried out on the existing footpath connecting the pier to Lai Chi Wo village and So Lo Pan. In addition, all trees are anticipated to be retained after the Project. Therefore, direct impact on trees due to the Project is not anticipated.

12.2.1.3 Though insurmountable impacts on trees are not anticipated for the Project, every effort should be exercised to preserve the existing trees on site and in the vicinity from tree preservation point of view. The following tree preservation and protection practices are recommended during the construction of the Project:

· No fencing, services, or signs other than the identification labels or markings shall be attached to any part of the trees;

· No trees shall be used as anchorages for ropes or chains used in guying or pulling or for equipment used for removing stumps, roots or other trees, or for any other purpose;

· No soil, materials, equipment or machinery shall be stockpiled or stored in country park/geopark (unless approval or written consent from relevant authorities are obtained);

· No site offices, workshops, canteens, containers or similar structures shall be installed within the country park/geopark (unless approval or written consent from relevant authorities are obtained). The engineer’s accommodation is anticipated to be erected on the temporary working platform/barge on sea during construction;

· Petrol, oil, bitumen, creosote, cement and other materials likely to be injurious to the trees shall be kept away from the trees, and any accidental spills of these materials shall be cleaned up immediately;

· No concrete mixing, gas tank filling, paintbrush and tool cleaning, or equipment maintenance shall be carried out in country park/geopark; and

· All building debris and chemical wastes shall be hauled away for proper disposal, and in any circumstances shall not be burned or buried on the Site or be disposed of by pouring them on the soil within the Site.

12.2.2 Operational Phase

12.2.2.1 The landscape and visual mitigation measures to be incorporated in the operational phase, and relevant agencies for the measures are summarised in Table 12.2 and shown in Figure 12.2.

Sensitive Design and Disposition of the Pier Structures

The proposed hard structures of the pier should be sensitively designed to become compatible with the existing landscape context. The footprint of the pier should also be minimised while optimising the berthing depth and length of the pier to reduce the landscape impact. The materials used for decoration such as external paint, metal cladding, tile, stone cladding should be compatible to the neighbouring natural environment. The orientation of the proposed hard structures of the pier should aim at minimising visual intrusion to visually sensitive receivers as far as practicable. Additional lights in the new pier will be kept to as minimal for safety purpose. Night-time lighting of the pier shall also be controlled to minimise glare impact to adjacent VSRs during the operation phase. If solar panels are to be installed as renewable energy source, non-reflective solar panels should be installed to avoid glare from direct or reflected sunlight.

14 Site Environmental Audit

14.1 Site Inspection

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

14.1.1.2 The ET shall be responsible for formulating the environmental site inspection programme as well as the deficiency and action reporting system, and for carrying out the site inspections. The proposal for rectification, if any, should be prepared and submitted to the ET Leader and IEC by the Contractor.

14.1.1.3 Regular site inspections shall be carried out and led by the ER and attended by the Contractor and ET at least once per week during the construction phase. The areas of inspection shall not be limited to the environmental situation, pollution control and mitigation measures within the site. It should also review the environmental conditions of locations outside the works area which is likely to be affected, directly or indirectly, by the construction site activities of the Project. The ET shall make reference to the following information in conducting the inspection. During the inspection, the following information should be referred to:

(i) EIA Report and EM&A Manual recommendations on environmental protection and pollution control mitigation measures;

(ii) ongoing results of the EM&A programme;

(iii) works progress and programme;

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

(v) contract specifications on environmental protection;

(vi) relevant environmental protection and pollution control legislations; and

(vii) previous site inspection results undertaken by the ET and others.

14.1.1.4 The Contractor shall keep the ER and ET Leader updated with all the relevant environmental related information on the construction contract necessary for him to carry out the site inspections. Site inspection results and associated recommendations for improvements to the environmental protection and pollution control efforts should be recorded and followed up by the Contractor in an agreed time-frame. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, and the deficiency and action reporting system formulated by the ET, to report on any remedial measures subsequent to the site inspections.

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

14.2 Environmental Compliance

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

14.2.1.2 In order to ensure the works comply with statutory requirements, all method statements of works should be submitted by the Contractor to the ER for approval and to the ET Leader for vetting to ensure sufficient environmental protection and pollution control measures have been included. EMIS is summarised in Appendix 4.1. Any proposed changes to the mitigation measures shall be certified by the ET Leader and verified by the IEC as conforming to the relevant information and recommendations contained in the EIA Report.

14.2.1.3 The ER and ET shall also review the progress and programme of the works to check that relevant environmental legislation has not been violated, and that any foreseeable potential for violating laws can be prevented.

14.2.1.4 The Contractor should provide the update of the relevant documents to the ET Leader so that checking can be carried out. The document shall at least include the updated Works Progress Reports, updated Works Programme, method statements, any application letters for different licenses / permits under the environmental protection laws, and copies of all valid licenses / permits. The site diary and environmental records shall also be available for inspection by the relevant parties.

14.2.1.5 After reviewing the document, the ET shall advise the IEC and the Contractor of any non-compliance with legislative requirements on environmental protection and pollution control so that they can timely take follow-up actions as appropriate. If the follow-up actions still result in potential violation of environmental protection and pollution control requirements, the ER and ET should provide further advice to the Contractor to take remedial action to resolve the problem.

14.2.1.6 Upon receipt of the advice, the Contractor shall undertake immediate actions to correct the situation. The ER and ET shall follow up to ensure that appropriate action has been taken in order to satisfy legal requirements.

14.3 Choice of Construction Method

14.3.1.1 At times during the construction phase, the Contractor may submit method statements for various aspects of construction. This state of affairs would only apply to those construction methods that the EIA has not imposed conditions while for construction methods that have been assessed in the EIA, the Contractor is bound to follow the requirements and recommendations in the EIA study. The Contractor’s options for alternative construction methods may introduce adverse environmental impacts into the Project. It is the responsibility of the Contractor and ET, in accordance with established standards, guidelines and EIA study recommendations and requirements, to review and determine the adequacy of the environmental protection and pollution control measures in the Contractor’s proposal in order to ensure no unacceptable impacts would result. To achieve this end, the ET shall provide a copy of the Proactive Environmental Protection Proforma as shown in Appendix 14.1 to the IEC for approval before commencement of work. The IEC should audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts.

14.4 Environment Complaints

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

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

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

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

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

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

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

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

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