2 Project Description

2.1 The Subject Site and its Environs

2.1.1 The Project involves the construction of a helipad by dredge and reclaim along the coastal waters at Pak Wan, northwest Peng Chau. The Project will be constructed off a natural, predominantly rocky, coastline.

2.1.2 The helipad deck will be located approximately 10 metres from the back of the Pak Wan shore (i.e., existing land). An access road will be constructed along the natural shoreline to link the proposed helipad with the existing Emergency Vehicular Access (EVA) located adjacent to Sea Crest Villa at northwest Peng Chau [Figure 2.1 refers].

2.1.3 The site location was selected after due consideration of the operational requirements and environmental impact potential of constructing and operating the Peng Chau helipad at each of 13 site options / alternatives [Section 2.2 of the Peng Chau Helipad EIA Report refers].

2.1.4 Peng Chau has been developed mainly with low-rise developments that are located in the central portion of the island. Northwest of Peng Chau and close to the proposed helipad site, there are low-rise (3 storeys) apartment type residential buildings and a medium-rise (7 storeys) public housing estate that are considered key air and noise sensitive receivers (SRs). Given the natural hilly topography at northwest Peng Chau there is no direct line of sight between these SRs and the proposed helipad site (i.e., there will be some shielding of helicopter noise from the SRs). However, Sea Crest Villa Blocks C and D, which are located approximately 160m southwest of the proposed helipad, have a direct line of site to the EVA works area.

2.2 Project Design

2.2.1 The proposed construction programme can be broadly summarised as presented by Table 2.1. The detailed construction schedule is presented in Appendix 2.1.

4 Air Quality

4.1 Introduction

4.1.1 Based on the air quality impact assessment, it has been identified that no significant impacts will arise from the construction and operation of the helipad through the proper implementation of dust control measures as required under the Air Pollution Control (Construction Dust) Regulation. While no specific control measures have been recommended, general air quality control measures are recommended for implementation as good site practices.

4.1.2 To check for implementation of these measures, the ET shall check on the implementation of air quality control measures by the Contractor as part of the regular site environmental audit.

4.2 Environmental Audit

4.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

4.2.2 In order to check that the air quality control measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections:

· Heights from which materials are dropped should be restricted as far as practicable to minimise fugitive dust arising from unloading/loading;

· All spraying of materials and surfaces should avoid excessive water usage;

· The working area for site clearance adjacent to Sea Crest Villa shall be sprayed with water or a dust suppression chemical immediately before, during and immediately after the operation so as to maintain the entire surface wet.

· For reclamation works, if a stockpile of dusty materials is more than 1.2 m high and within 50m of Peng Lei Road or the Pak Wan footpath, the stockpile shall be properly treated and sealed with latex, vinyl, bitumen or other suitable surface stabilizer.

· Immediately before leaving a construction site, every vehicle shall be washed to remove any dusty materials from its body and wheels.

· Travelling speeds should be controlled to reduce traffic induced dust dispersion and re-suspension within the site from the operating haul trucks

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

· Erection of hoarding of not less than 2.4 m high from ground level along the site boundary.

· Any stockpile of dusty materials shall be either: (a) covered entirely by impervious sheeting; (b) placed in an area sheltered on the top and the 3 sides; or (c) sprayed with water or a dust suppression chemical so as to maintain the entire surface wet.

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

4.2.3 All the dust control measures as recommended in the Air Pollution Control (Construction Dust) Regulation, where applicable, should also be implemented.

5 Noise

5.1 Introduction

5.1.1 During the construction phase of the helipad, power mechanical equipment (PME) used for the helipad construction will be the primary noise sources. The key noise generating activities include:

· Site clearance for the erection of site office, hoarding and fencing;

· Reclamation for the helipad and the Emergency Vehicle Access (EVA); and

· Construction of helipad and EVA.

5.1.2 Noise sensitive receivers (NSRs) have been identified in accordance with Annex 13 of the EIAO TM. As required under Clause 3.4.5.2 (iii) (b) of the EIA Study Brief, the selection of representative NSRs has been presented to and agreed by the Authority prior to commencement of this noise impact assessment.

5.2 Noise Monitoring Parameters

5.2.1 Monitoring of noise levels at the proposed sensitive receiver locations shall be undertaken by the ET during the baseline and construction phases of the project to ensure that any increase in noise levels as a result of the construction works are readily detected and rectified in a timely fashion.

5.2.2 The construction noise level will be measured in terms of the A-weighted equivalent continuous sound pressure level (L_eq). Noise measurements will be carried out with an integrating sound level meter using the ‘fast’ response mode. L_{eq(30 min)} will be used as the monitoring parameter for the time period between 07:00-19:00 hours on normal weekdays. For all other time periods, L_{eq(5 min)} will be employed for comparison with the Noise Control Ordinance criteria.

5.2.3 As supplementary information for data auditing statistical results such as L₁₀ and L₉₀ will also be obtained for reference.

5.2.4 In addition to carrying out noise monitoring, control and mitigation measures are recommended for implementation by the Contractor. The ET shall check the implementation of these measures during the regular site environmental audits. As described in Section 9 of this Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

5.3 Monitoring Equipment

5.3.1 As referred to in the Technical Memorandum (TM) issued under the Noise Control Ordinance (NCO), sound level meters in compliance with the International Electrical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications will be used for carrying out the noise monitoring.

5.3.2 Immediately prior to and following each noise measurement the accuracy of the sound level meter will be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agrees to within 1.0dB. Calibration equipment to be used should meet IEC 942, Type 1 specifications, and succeeding standard specifications for sound level meters applicable in Hong Kong. Annual calibration of the noise monitoring equipment by an accredited laboratory will be carried out for compliance with IEC publications 651 and 804 and any other relevant standards.

5.3.3 Noise measurements shall not be made if the wind speed exceeds 5ms^-1 or if gusts exceed 10ms^-1. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in ms^-1. Measurements shall not be made while air temperatures are outside the manufacturer’s specified range or when other intrusive noise sources (other than influencing factors) are apparent at the assessment point.

5.3.4 Sufficient noise measuring equipment and associated instrumentation should be available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation will be clearly labelled, stored and maintained according to the manufacturer’s instructions.

5.4 Monitoring Procedure

5.4.1 Monitoring will be carried out with reference to the following documents:

· Technical Memorandum on the Assessment of Noise from Construction Work other than Percussive Piling, Hong Kong Government;

· Technical Memorandum on the Assessment of Noise from Construction Works in Designated Areas, Hong Kong Government

· Technical Memorandum for the Assessment of Noise from places other than Domestic Premises, Public Places or Construction Sites, Hong Kong Government;

· or succeeding standards and guidelines.

5.4.2 The monitoring stations will normally be at a point 1 m from the exterior of the sensitive receivers building facade and be at a position 1.2 m above the ground. When a measurement is to be made of noise being received at a place other than a building, the assessment point will be at least 1.2 m above ground level, at an appropriate point. The appropriate measurement positions should be at least 3.5 m from any reflecting surface other than the ground and have an unobstructed view of the Site. In such instances where free-field measurements are conducted, a positive correction of 3dB(A) will be applied to the relevant target limits.

5.4.3 The microphone of the sound level meter will be so orientated that it is pointing in the direction of the Site and at the source of noise being monitored such that the microphone is perpendicular to the plane of the incident sound-waves. It will be protected using an appropriate windshield. To avoid reflections from the operator’s body, the microphone will be mounted on a tripod, whether attached to the sound level meter or not. Noise measurements will be rounded to the nearest whole dB, with values of 0.5 dB or more being rounded upwards.

5.4.4 Noise will not be monitored in the presence of mist, fog or rain, when wind is at a steady speed exceeding 5 m/s, or when gusts exceed 10m/s.

5.4.5 For monitoring locations located in the vicinity of the sensitive receivers, care shall be taken to cause minimal disturbance to the occupants during monitoring.

5.4.6 Noise measurements shall be recorded on a field data sheet together with relevant information including project name, date and time of sampling, monitoring location and parameters, site observations and remarks. A sample field data sheet is attached in Appendix 10.1.

5.5 Proposed Monitoring Location

5.5.1 The noise impact assessment presented in the EIA report indicated that the unmitigated construction noise levels at all NSRs are found to comply with the daytime noise standards stated in Table 1B, Annex 5 of EIAO TM. Noise mitigation measures have been recommended in the EIA report and shall be implemented by the Contractor in accordance with the requirements under the Noise Control Ordinance. The Contractor shall be responsible for the design and implementation of the noise mitigation measures.

5.5.2 Figure 5.1 illustrates the location of the proposed noise monitoring location (N1) identified at this early planning stage. N1 corresponds to NSR1, a residential premise located about 160 metres southwest of the helipad site, as identified in the EIA report. 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 ER and agreement from the IC(E) and EPD of the proposal.

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

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

· Close to the noise sensitive receivers (as defined by the EIAO TM); and

· For monitoring locations located in the vicinity of the sensitive receivers, care shall be taken to cause minimal disturbance to occupants during monitoring.

5.6 Baseline Monitoring

5.6.1 Daily noise monitoring shall be carried out at all designated monitoring locations for a period of at least two weeks prior to the commencement of the Work to establish the baseline noise conditions. The frequency of monitoring for each station will include at least:

· One set of measurements between 07:00 - 19:00 hours on normal weekdays;

· One set of measurements between 19:00 - 23:00 hours on normal weekdays;

· One set of measurements between 23:00 - 07:00 hours of next day; and

· One set of measurements between 07:00 - 19:00 hours on holidays.

5.7 Impact Monitoring

5.7.1 Noise monitoring shall be carried out at all the designated monitoring stations. Noise monitoring shall be conducted on a weekly basis when noise-generating activities are underway. One set of measurements shall be taken between 07:00-19:00 hours on normal working days.

5.7.2 General construction works carried out during restricted hours are controlled by the Construction Noise Permit System, under the NCO. The Contractor shall apply for a Noise Permit and abide by the requirements of the permit should works be necessary in the restricted hours.

5.7.3 In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Event/Action Plans shall be carried out [Appendix 5.1 refers]. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.

5.8 Event and Action Plan

5.8.1 The Action Limit levels for construction noise are defined in Table 5.1. Should non-compliance of the noise quality criteria occur, actions will be carried out in accordance with the Event/Action Plan [Appendix 5.1 refers].

Table 5.1 Action Limit Levels for Construction Noise

Time Period	Action	Limit
07:00 – 19:00 hours on normal weekdays	When one documented complaint is received	75 dB(A)

5.9 Noise Mitigation Measures

5.9.1 The EIA report has found that cumulative noise exceedances would be recorded at nearby NSRs if no mitigation measures were implemented. However, with the implementation of appropriate mitigation measures, as detailed in Section 4 of the EIA report, noise impacts of construction can be reduced to acceptable levels that are in compliance with the requirements of the Noise Control Ordinance.

5.9.2 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

5.9.3 In order to check that the noise control measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections:

· Noisy equipment and noisy activities should be located as far away from the NSRs as is practical;

· Use of silence equipment and installation of temporary and movable noise barriers. Movable barriers shall be positioned as close as possible to powered mechanical equipment so that they are not visible to sensitive receivers;

· Unused equipment should be turned off;

· Powered mechanical equipment should be kept to a minimum and the parallel use of noisy equipment / machinery should be avoided; and

· Regular maintenance of all plant and equipment.

5.9.4 The Contractor shall observe and comply with the relevant statutory requirements and guidelines.

5.9.5 Operational noise monitoring is impracticable as there are no scheduled helicopter flights, and so operational phase noise monitoring is not recommended.

5.9.6 Should the need arise, the local community may lodge noise complaints with the Islands District Office by the following means:

Fax: 2815 2291
Email: dois@had.gov.hk
Address: Islands District Office, Harbour Building, 20th Floor, 38 Pier road, Central.

6 Waste Management

6.1 Introduction

6.1.1 Based on the initial waste generation assessment, it has been identified that minimal volumes of C&D materials (including inert and non-inert materials), dredged sediments, chemical waste and general refuse will be generated from the construction activities.

6.1.2 Through proper onsite handling and storage (covered containers), reuse (of inert C&D materials) and off-site disposal (via approved waste collector and to approved waste facilities and/or disposal grounds) the generation, handling and disposal of these wastes will not give rise to any adverse environmental impacts. However, given the potential for environmental impacts to arise from improper waste management (e.g. visual impact, nuisance, etc.), it is recommended that control and mitigation measures be implemented as part of general good site practices.

6.2 Environmental Audit

6.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

6.2.2 In order to check that the waste control and mitigation measures have been implemented by the Contractor as good site practices, the ET shall include the following items as part of their site inspections and audit:

i) The reuse/recycling of all materials on site shall be investigated prior to treatment/disposal off site;

ii) Good site practices shall be adopted from the commencement of works to avoid the generation of waste, reduce cross contamination of waste and to promote waste minimization practices;

iii) All waste materials shall be sorted on site into inert and non-inert C&D materials, and where the materials will be recycled or reused, these shall be further segregated. The Contractor shall be responsible for identifying which materials can be recycled/reused, whether on site or off site. In the event of the latter, the Contractor shall make arrangements for the collection of the recyclable materials. Any remaining non-inert waste shall be collected and disposed of to the refuse transfer station whilst any inert C&D material shall be re-used on site as far as possible. Alternatively, if no use of the inert material can be found on site, the material can be delivered to a public filling area or public fill bank after obtaining the appropriate licence;

iv) With reference to ETWB TCW No. 31/2004, Trip-ticket System for Disposal of Construction and Demolition Material, a trip ticket system should be established at the outset of the construction of the helipad to monitor the disposal of C&D and solid wastes from the site to public filling facilities and landfills;

v) Dredged sediments shall be handled in accordance with the ETWB TCW No. 34/2002 on Management of Dredged/Excavated Sediment and where the sediments cannot be reused onsite, arrangements shall be made with the MFC for allocation of dumping space;

vi) Stockpiling is not envisaged, however if it becomes unavoidable, stockpiling in any vegetated areas shall be avoided (as far as possible) and shall be covered with tarpaulin and/or watered to prevent windblown dust and/or surface runoff;

vii) Under the Waste Disposal (Chemical Waste) (General) Regulation, the Contractor shall register with EPD as a Chemical Waste Producer if there is any use of chemicals on site including lubricants, paints, diesel fuel, etc. Only licensed chemical waste collectors shall be employed to collect any chemical waste generated at site. The handling, storage, transportation and disposal of chemical wastes shall be conducted in accordance with the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes and A Guide to the Chemical Waste Control Scheme both published by EPD;

viii) A sufficient number of covered bins shall be provided on site for the containment of general refuse to prevent visual impacts and nuisance to sensitive receivers. These bins shall be cleared daily and the collected waste disposed of to the refuse transfer station on Tai Lei. Further to the issue of ETWBTC (Works) No. 6/2002A, Enhanced Specification for Site Cleanliness and Tidiness, the Contractor is required to maintain a clean and hygienic site throughout the project works;

ix) All chemical toilets shall be regularly cleaned and the nightsoil collected and transported by a licensed contractor to a Government Sewage Treatment Works facility for disposal;

x) Tool-box talks should be provided to workers about the concepts of site cleanliness and appropriate waste management procedures, including waste reduction, reuse and recycling; and

xi) A recording system for the amount of wastes generated, recycled and disposed of (including the disposal sites) shall be proposed by the Contractor, and the ET Leader shall include a summary of such information in each monthly EM&A Report.

6.2.3 The Contractor shall also observe and comply with the relevant statutory requirements and guidelines and their updated versions.

7 Water Quality

7.1 Introduction

7.1.1 Given the scale and nature of the Project the initial water quality assessment conducted under the EIA study indicates that minimal disturbances will be generated and thus no unacceptable water quality impacts are foreseen.

7.1.2 Although no significant adverse water quality impacts are predicted and no specific mitigation is necessary, general control and mitigation measures are recommended for implementation by the Contractor as good site practice.

7.2 Environmental Audit

7.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

7.2.2 The ET shall include the measures outlined below as part of their site inspections to check that the Contractor has implemented the waste control and mitigation measures as good site practices.

7.2.3 As a precautionary good site practice measure, it is recommended that silt curtains be installed around the dredging locations prior to the commencement of dredging. The silt curtains shall reach seabed level.

7.2.4 The following good site practices are also recommended to further minimize the potential water quality impacts:

· The daily dredging volume should be spread as evenly as possible over the working hours whenever practical to avoid sudden surge of pollution elevation during short spells;

· Special care should be taken during lowering and lifting grabs to minimize unnecessary disturbance to the seabed;

· To ensure vessels used have adequate clearance of the seabed in order to reduce undue turbidity generated by turbulence from vessel movement or propeller wash;

· Barges should be fitted with tight fitting seals to their bottom openings to prevent leakage of material;

· The Contractor should ensure that grabs are tightly closed and the hoist speed is suitably low;

· Barges should not be filled to a level which will cause overflow of materials during loading and transportation; and

· Large objects should be removed from the grab to avoid losses from partially closed grabs.

· The dredging shall be monitored and a daily record shall be kept to ensure the dredging rate would not exceed the assumed maximum daily rate of 465 cubic metres as recommended in the EIA.

7.2.5 The Contractor shall also observe and comply with the relevant statutory requirements and guidelines.

8 Ecology & fisheries

8.1 Introduction

8.1.1 Based on the ecological and fisheries impact assessments of the EIA report, it was identified that the project will not result in any significant sub-tidal habitat loss and there is not anticipated to be any impact on the hard coral community from dredge and reclaim so long as good working practices are followed.

8.1.2 While no specific mitigation measures are considered necessary, the control and mitigation measures recommended for water quality are relevant to the mitigation against ecological and fisheries impacts and as such should be implemented by the Contractor as part of their day-to-day good site practice. The ET should check the implementation of these measures during the regular site environmental audit.

8.2 Environmental Audit

8.2.1 As described in Section 9 of the Manual, the ET Leader is responsible for formulating an environmental site inspection, deficiency and action reporting system, and for carrying out site inspections under the EM&A programme.

8.2.2 The ET shall include the measures outlined in Section 7.2.4 above as part of their site inspections to check that the Contractor has implemented the waste control and mitigation measures as good site practices to not only control water quality but also to protect the sub- and inter-tidal ecology around the helipad site.

8.2.3 As a precautionary good site practice measure, it has been recommended that silt curtains be installed around all dredging locations prior to the commencement of dredging. The silt curtain(s) shall reach seabed level.

8.2.4 In addition to the good site practices recommended to further minimize the potential water quality impacts [refer to Section 7.2.4], particular care should be taken when decommissioning the silt curtain to avoid sudden dispersion of muddy water which may cause adverse impact to the nearby marine life.

9 Site Environmental Audit

9.1 Site Surveillance
