2. CONSTRUCTION AIR QUaLITY

2.1. Introduction

2.1.1 This section presents the requirements, methodology, equipment, monitoring locations, criteria and protocols for the monitoring and audit of air quality impacts during the construction phase of the Project. No exceedances of the Hong Kong Air Quality Objectives (HKAQO) criteria were predicted in the EIA report at Air Sensitive Receivers (ASRs) in the vicinity of the construction sites and it is concluded that the Project would not cause any adverse air quality impacts. However, environmental monitoring and audit is recommended to monitor the effectiveness of the proposed mitigation measures.

2.1.2 The objectives of the air quality monitoring are:

· To identify the extent of construction dust impacts on sensitive receivers;

· To determine the effectiveness of mitigation measures to control fugitive dust emission from activities during construction 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 (A/L) Levels for air quality as defined in this Manual.

2.2. Methodology and Criteria

2.2.1 The criteria against which ambient air quality monitoring shall be assessed are:

· The Hong Kong Air Quality Objectives (AQOs) for TSP, 24-hour TSP levels of 260mg m^-3

· The 1-hour TSP limit of 500mg m^-3 under EIAO TM.

2.2.2 These levels are not to be exceeded at Air Sensitive Receivers (ASRs).

2.2.3 Monitoring and audit of the TSP levels shall be carried out by the ET to detect any deteriorating air quality and to take timely action to rectify such situation.

2.2.4 1-hour or 24-hour average TSP levels shall be measured to indicate the impacts of construction dust on air quality. The 24-hour average TSP levels shall be measured by referring to the standard high volume sampling method as set out in the Title 40 of the United States Code of Federal Regulations, Chapter I (Part 50) Appendix B. Upon agreement from the IEC, 1-hour average TSP levels can be measured by direct reading methods to indicate short-term impacts.

2.2.5 All relevant data including temperature, pressure, wind speed and direction, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, other local atmospheric factors affecting or affected by site conditions and work progress of the concerned site, etc. shall be recorded in detail. 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 C. The ET may modify the data record sheet for this EM&A programme.

2.3. Monitoring Equipment

2.3.1 The ET shall be responsible for the provision of the monitoring equipment. The ET shall provide sufficient number of high volume sampler (HVS) and / or direct reading dust meter with appropriate calibration kit for carrying out the baseline, regular impacts monitoring and ad-hoc monitoring. The HVSs shall be equipped with an electronic mass flow controller and be calibrated against a traceable standard at regular intervals. All the equipment, calibration kit, filter papers, etc, shall be clearly labelled.

2.3.2 Calibration of dust monitoring equipment shall be conducted as specified by the manufacturer. The calibration data shall be properly documented for future reference. All the data shall be converted into standard temperature and pressure condition.

2.3.3 A HVS in compliance with the following specifications shall be used for carrying out the 1-hour and 24-hour TSP monitoring:

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

· Equipped with a timing / control device for 24 hours operation;

· Installed with elapsed-time meter for 24 hours operation;

· Capable of providing a minimum exposed area of 406 cm² (63 in²);

· Incorporated with an electronic mass flow rate controller or other equivalent devices;

· Equipped with a flow recorder for continuous monitoring;

· Provided with a peaked roof inlet;

· Incorporated with a manometer;

· Able to hold and seal the filter paper to the sampler housing at horizontal position;

· Easy to change the filter; and

· Capable of operating continuously for 24-hour period.

2.3.4 The flow-rate of the sampler before and after the sampling exercise with the filter in position shall be verified to be constant and be recorded down on the data sheet as mentioned in Appendix C.

2.4. Laboratory Measurement / Analysis

2.4.1 Filter paper shall be labelled before sampling. It shall be a clean filter paper with no pinholes, and shall be conditioned in a humidity-controlled chamber for over 24-hour and be pre-weighed before use for the sampling.

2.4.2 After sampling, the filter paper loaded with dust shall be kept in a clean and tight sealed bag. The filter paper shall then be returned to the laboratory for reconditioning in the humidity-controlled chamber followed by accurate weighing by an electronic balance. The balance shall be regularly calibrated against a traceable standard.

2.4.3 All the collected samples shall be kept in a good condition for 6 months before disposal.

2.5. Monitoring Locations

2.5.1 Besides the distance to the emission sources, the nature and scale of works are considered for selection of monitoring location. The cut-and-cover works area in front of Comfort Building involves only small amount of excavation. In addition, the predicted TSP concentrations (both 1-hr and 24-hr) at ASR A14 (Comfort Building) are well below the EIAO-TM criteria. Hence A2 is identified as the representative dust monitoring location as listed in Table 2.1 below and shown in Figure 2.1.

Table 2.1 Proposed Dust Monitoring Stations

Identification No.	ASR ID in EIA Report	Air Quality Monitoring Location
M1	A2	Hai Phong Mansion

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

· At the site boundary or such locations close to the major dust emission source;

· Close to the air sensitive receivers;

· Proper position/sitting and orientation of the monitoring equipment; and

· Take into account the prevailing meteorological conditions.

2.5.3 When positioning the sampler, the following points shall be noted:

· A horizontal platform with appropriate support to secure the samplers against gusty wind shall be provided;

· No two samplers shall be placed less than 2m apart;

· The distance between the sampler and an obstacle, such as buildings, must be at least twice the height that the obstacle protrudes above the sampler;

· A minimum of 2m of separation from walls, parapets and penthouses is required for rooftops samplers;

· A minimum of 2m of separation from any supporting structure, measures horizontally is required;

· No furnace or incinerator flue is nearby;

· Airflow around the sampler is unrestricted;

· The sampler is more than 20m from the dripline;

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

· Permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

· A secured supply of electricity is needed to operate the samplers.

2.6. Baseline Monitoring

2.6.1 Baseline monitoring shall be carried out to determine the ambient 1-hour and 24‑hour TSP levels at the monitoring locations prior to the commencement of the Project works. During the baseline monitoring, there shall not be any construction or dust generating activities in the vicinity of the monitoring stations. The baseline monitoring will provide data for the determination of the appropriate Action levels with the Limit levels set against statutory or otherwise agreed limits.

2.6.2 Baseline monitoring shall be carried out at each designated monitoring location for a continuous period of at least 14 days prior to the commissioning of the construction works to obtain daily 24-hour TSP samples. 1-hour sampling shall also be done at least 3 times per day. Baseline monitoring shall be carried out under typical weather conditions. General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources shall also be recorded throughout the baseline monitoring period.

2.6.3 In case the baseline monitoring cannot be carried out at the designated monitoring locations during baseline monitoring period, the ET shall carry out the monitoring at alternative locations which can effectively represent the baseline conditions at the impact monitoring locations.

2.6.4 In exception cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with EPD to agree on an appropriate set of data to be used as a baseline reference.

2.6.5 If the ET considers that significant changes in the ambient conditions have arisen, a repeat of the baseline monitoring may be carried out to update the baseline levels. The monitoring shall be at times when the contractor's activities are not generating dust. The revised levels, in turn, the air quality criteria, shall be agreed with EPD.

2.7. Impact Monitoring

2.7.1 The ET shall carry out impact monitoring during construction phase of the Project. For regular impact monitoring, a sampling frequency of at least once per week shall be strictly observed at all of the monitoring station for 24-hour TSP monitoring.

2.7.2 In case of non-compliance with the air quality criteria, more frequent monitoring, as specified in the Event and Action Plan in Table 2.3, shall be conducted within the 24 hours after the non-compliance is known. 1-hour TSP monitoring shall be conducted after the non-compliance is known instead of 24-hour TSP monitoring. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified.

2.8. Event and Action Plan

2.8.1 The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring. The ET shall compare the impact monitoring results with air quality criteria set up for 1-hour and 24-hour TSP. Table 2.2 shows the air quality criteria, namely Action and Limit Levels to be used. Should non-compliance of the air quality occur, action in accordance with the Event and Action Plan in Table 2.3 shall be carried out.

3. noise

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.

3.2. Construction Noise Parameters

3.2.1 The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (L_eq). L_{eq (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, L_{eq (5 minutes)} shall be employed for comparison with the Noise Control Ordinance (NCO) criteria.

3.2.2 A sample data record sheet based on the one presented in EM&A Guidelines for Development Projects in Hong Kong is shown in Appendix C. The ET may modify the data record sheet for this EM&A programme.

3.3. Construction Monitoring Equipment

3.3.1 As referred to 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. The calibration of the sound level meters and their respective calibrators shall be carried out in accordance with the manufacturer’s requirements.

3.3.2 Noise measurements should not be made in the presence of fog, rain, wind with a steady speed exceeding 5ms^-1 or wind with gusts exceeding 10ms^-1.

3.3.3 The ET is responsible for providing sufficient and suitable noise measuring equipment and associated instrumentation for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

3.4. Construction Noise Monitoring Locations

3.4.1 Based on the EIA Report, the locations designated for construction noise monitoring are listed in Table 3.1 and illustrated in Figure 2.1.

Table 3.1 Noise Monitoring Stations during Construction Phase

Identification No.	NSR ID in EIA Report	Noise Monitoring Location
M1	N1	Hai Phong Mansion
M2	N3	Comfort Building
M3	N4	Burlington Arcade

3.4.2 As residual noise impact is predicted in the EIA Study, it is recommended to set up a community liaison channel. Other than handling public enquiry/complaint, the management office of Milton Mansion can inform the proponent through this channel if any part of the building becomes residential use.

3.4.3 The status and location of noise sensitive receivers may change after issuing this manual. If such cases exist, the ET shall propose updated monitoring locations and seek approval from EPD. 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 TM

· Assurance of minimal disturbance to the occupants during monitoring

3.4.4 The monitoring station shall normally be at a point 1m from the exterior of the noise sensitive facade and be at a position 1.2m above ground. If there is a problem with access to the normal monitoring position, an alternative position should be chosen. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions.

3.5. Construction Noise Baseline Monitoring

3.5.1 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 2 weeks.

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

3.6. Construction Noise Impact Monitoring

3.6.1 Noise monitoring shall be carried out at the designated monitoring stations. The monitoring frequency shall depend on the scale of the construction activities. When noise generating activities are underway a weekly monitoring frequency (one set of measurement between 0700 and 1900 hours on normal weekdays) shall be adopted.

3.6.2 If construction works are extended to include works during the hours of 1900 – 0700 as well as public holidays and Sundays, applicable construction noise permits (CNP) under NCO shall be obtained by the Contractor.

3.6.3 In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in Event and Action Plan in Table 3.3 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.

3.6.4 To address the residual construction noise impact predicted in the EIA Study, it is recommended to set up a community liaison channel to handle any public query/complaint. This communication channel with the management office of Milton Mansion is set up such that the proponent would be informed at once if any part of the building becomes residential use.

3.7. Event and Action Plan for Construction Noise

3.7.1 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)*

* Reduced to 70dB(A) for schools or institution and 65dB(A) during school examination periods

3.7.2 To account for cases where ambient noise levels as identified by baseline monitoring approach or exceed the stipulated limit level prior to the commencement of construction, a Maximum Acceptable Impact Level may be defined and agreed with EPD which incorporates the baseline noise value and the identified construction noise limit level by logarithmically summing the two. The amended level will therefore be greater than the limit level and will represent the maximum allowable noise level at a specific monitoring station. Correction factors for the effect of acoustic screening and / or architectural features of NSRs may also be applied as specified in the TM.

3.8. Construction Noise Mitigation Measures

3.8.1 The EIA report indicated some noise exceedance for limited periods of time. Therefore, appropriate mitigation measures and good site practices are recommended to be properly implemented. The mitigation measures recommended in the EIA report are summarised below:

· Use of silenced type of powered mechanical equipment, which should be in accordance with BS 5228: Part 1, 1997 during construction;

· Use of movable noise barrier;

· Use of noise enclosure / acoustic shed;

· Use of silencer;

· Use of noise insulating fabric;

· Decking over the excavation areas at the Entrance A1 and satellite concourse; and

· Implementation of the following good site practices:

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

Ø Silencers or mufflers on construction equipment shall be utilised and shall be properly maintained during the construction program.

Ø Mobile plant, if any, shall be sited as far away from NSRs as possible.

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

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

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

3.8.2 A community liaison channel will be set up to handle any public enquiry and complaint.

3.8.3 The implementation schedule for the recommended mitigation measures is presented in Appendix B.

3.9. Operation Ventilation Noise

3.9.1 The EIA report has provided the maximum allowable sound power levels (SWLs) for the ventilation shafts to be operated. The SWL criteria shall be implemented and refined by the Contractor. The Contractor should also implement any necessary mitigation measures to ensure the compliance of the operation airborne noise levels with the TM’s stipulated noise standard. A summary of Max SWL for ventilation shafts is given in the following table:

Table 3.4 Summary of Max SWL for Ventilation Shafts

*Source Location	**Direction Facing	Shortest horizontal distance to Milton Mansion, m	Maximum SWL at 0700-2300, dB(A)	Maximum SWL at 2300-0700, dB(A)
Tung Ying Building	West (Nathan Road)	17	92	85
Tung Ying Building	South (Granville Road)	15	91	84
Hotel Miramar	West (Nathan Road)	44	100	93

Note: (*) Only one of the sources would be in operation as the exact locations for exhaust or smoke extraction are still under design.

(**) The vent shaft would be located at one direction only. The exact location of the shaft opening from Tung Ying Building is still under design. MTRCL would take the responsibility of the design and maintenance of the proposed ventilation system and implement the noise mitigation measures to ensure the noise criteria could be met.

3.9.2 However, it is still recommended that the following noise reduction measures shall be considered as far as practicable during construction:

· Choose quieter plant such as those which have been effectively silenced.

· Include noise levels specification when ordering new plant (including chillier and E/M equipment).

· Locate fixed plant/louver away from any NSRs as far as practicable.

· Locate fixed plant in walled plant rooms or in specially designed enclosures.

· Locate noisy machines in a basement or a completely separate building.

· Install direct noise mitigation measures including silencers, acoustic louvers and acoustic enclosure where necessary.

· Develop and implement a regularly scheduled plant maintenance programme so that equipment is properly operated and serviced in order to maintain controlled level of noise. The programme should be implemented by properly trained personnel.

4. CONSTRUCTION WATER QUALITY

4.1. Introduction

4.1.1 The water quality impact assessment in the EIA Report identified that no adverse impact would occur during the construction of the Project provided the recommended mitigation measures were correctly implemented. It is recommended that regular site inspections shall be undertaken to inspect the construction activities and works areas in order to ensure the recommended mitigation measures are properly implemented.

4.2. Site Inspection

4.2.1 Regular site inspection should be conducted to inspect the construction activities and works areas in order to ensure the recommended mitigation measures are properly implemented, which is adequate for protection of water resources.

4.3. Mitigation Measures

4.3.1 Mitigation measures recommended for the construction phase of the Project are summarized below. The implementation schedule of the recommended water quality mitigation measures is presented in Appendix B.

Construction Site Run-off and Drainage

4.3.2 Construction runoff and site drainage should be prevented or minimized in accordance with the guidelines stipulated in ProPECC PN 1/94 “Construction Site Drainage”. The specified mitigation measures and practices include the following:

· Provision of perimeter drains to intercept off-site water around the site with internal drainage works and erosion and sedimentation control facilities implemented. These shall be constructed in advance of site formation works and earthworks. Earth bunds or sand bag barriers should be provided on-site to direct storm water to silt removal facilities. The design of the temporary on-site drainage system will be undertaken by the Contractor prior to the commencement of construction.

· All drainage facilities and erosion and sediment control structures should be regularly inspected and maintained to ensure proper and efficient operation at all times and particularly during rainstorms. Deposited silt and grit should be regularly removed, at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.

· Exposed slope/soil surface should be covered by tarpaulin as soon as possible to reduce the potential of soil erosion. Arrangements should always be in place to ensure that adequate surface protection measures can be safely carried out well before the arrival of a rainstorm. Other measures that need to be implemented before, during and after rainstorms are summarized in ProPECC PN 1/94.

· Open stockpiles of construction materials (e.g. aggregates, sand and fill material) or construction wastes on-site of more than 50m³ should be covered with tarpaulin or similar fabric during rainstorms.

· Construction works should be programmed to minimise surface excavation works during the rainy seasons (April to September). All exposed earth areas should be completed and vegetated as soon as possible after earthworks have been completed, or alternatively, within 14 days of the cessation of earthworks where practicable. If excavation of soil cannot be avoided during the rainy season, or at any time of year when rainstorms are likely, exposed surfaces should be covered by tarpaulin or other means.

· Manholes should always be adequately covered and temporarily sealed so as to prevent silt, construction materials or debris being washed into the drainage system and storm runoff being directed into foul sewers.

· Precautions be taken at any time of year when rainstorms are likely, actions to be taken when a rainstorm is imminent or forecasted, and actions to be taken during or after rainstorms are summarised in Appendix A2 of ProPECC PN 1/94.

· All vehicles and plant should be cleaned before leaving a construction site to ensure no earth, mud, debris and the like is deposited by them on roads. An adequate designed and sited wheel washing facilities should be provided at every construction site exit, where practicable. Wash-water should have sand and silt settled out and removed at least on a weekly basis to ensure the continued efficiency of the process. The section of access road leading to, and exiting from, the wheel-wash bay to the public road should be paved with sufficient backfall toward the wheel-wash bay to prevent vehicle tracking of soil and silty water to public roads and drains.

· Oil interceptors should be provided in the drainage system downstream of any oil/fuel pollution sources. The oil interceptors should be emptied and cleaned regularly to prevent the release of oil and grease into the storm water drainage system after accidental spillage. A bypass should be provided for the oil interceptors to prevent flushing during heaving rain.

· Construction solid waste, debris and rubbish on site should be collected, handled and disposed of properly to avoid water quality impacts.

Underground Works

4.3.3 Underground works should be conducted sequentially to limit the amount of construction runoff generated from exposed areas during the wet season (April to September).

4.3.4 Uncontaminated discharge should pass through settlement tanks prior to off-site discharge.

4.3.5 The wastewater with a high concentration of SS should be treated (e.g. by settlement in tanks with sufficient retention time) on-site prior to off-site discharge. Oil interceptors would also be installed to remove the oil, lubricants and grease from the wastewater if required.

Sewage Effluent

4.3.6 Temporary sanitary facilities, such as portable chemical toilets, should be employed on-site where necessary to handle sewage from the workforce. A licensed contractor would be responsible for appropriate disposal of waste matter and maintenance of these facilities.

General Construction Site Activities

4.3.7 Debris and rubbish generated on-site should be collected, handled and disposed of properly to avoid being flushed or blown by wind into the drainage culvert. Stockpiles of cement and other construction materials should be kept covered when not being used.

4.3.8 Oils and fuels should only be used and stored in designated areas which have pollution prevention facilities. To prevent spillage of fuels and solvents, all fuel tanks and storage areas should be provided with locks and be sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity of the largest tank. The bund should be drained of rainwater after a rain event.

5. waste management implications

5.1. Introduction

5.1.1 Waste management during the construction phase will be the contractor’s responsibility. The contractor must confirm that all wastes produced during the construction phase of the Project are handled, stored and disposed of in accordance with good waste management practices and EPD’s regulations and requirements. The recommended mitigation measures in the EIA Report should form the basis of the Waste Management Plan to be developed by the Contractor in the construction stage.

5.1.2 Waste materials generated during construction activities, such as construction and demolition (C&D) materials and general refuse, are recommended to be audited at regular intervals to ensure that proper storage, transportation and disposal practices are being implemented. The Contractor would be responsible for the implementation of any mitigation measures to minimise waste or redress problems arising from the waste materials.

5.2. Mitigation Measures

5.2.1 Mitigation measures for waste management as recommended in the EIA Report are summarised below. With the appropriate handling, storage and removal of waste arising during the construction works as defined below, the potential to cause adverse environmental impacts would be minimised.

5.2.2 The implementation schedule of the recommended mitigation measures is presented in Appendix B. During the site inspections, the ET shall pay special attention to the issues relating to waste management and check whether the Contractor has implemented the recommended good site practices and other mitigation measures.

Good Site Practices

5.2.3 Adverse impacts related to waste management are not expected to arise, provided that good site practices are strictly followed. Recommendations for good site practices during the construction activities include:

· Nomination of an approved person, such as a site manager, to be responsible for good site practices, arrangements for collection and effective disposal to an appropriate facility, of all wastes generated at the site.

· Training of site personnel in proper waste management and chemical waste handling procedures.

· Provision of sufficient waste disposal points and regular collection for disposal.

· Appropriate measures to minimise windblown litter and dust during transportation of waste by either covering trucks or by transporting wastes in enclosed containers.

· Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors.

· A Waste Management Plan should be prepared and submitted to the Engineer for approval. One may make reference to ETWB TCW No. 19/2005 for details.

· A recording system for the amount of wastes generated, recycled and disposed (including the disposal sites) should be proposed.

5.2.4 In order to monitor the disposal of C&D materials at public fill reception facilities, as appropriate, and to control fly tipping, a trip-ticket system should be included as one of the contractual requirements. One may make reference to ETWB TCW No. 31/2004 for details. The use of a trip-ticket system would be required to avoid any illegal or unplanned dumping of waste generated by the Project.

Waste Reduction Measures

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

· 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 by providing separate labelled bins to enable this waste to be segregated from other general refuse generated by the workforce;

· Any unused chemicals or those with remaining functional capacity shall be recycled;

· 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 generated and avoid unnecessary generation of waste.

5.2.6 In addition to the above measures, specific mitigation measures are recommended below for the identified waste arisings to minimise environmental impacts during handling,

Construction and Demolition Material

5.2.7 Within stockpile areas, the following measures should be taken to control potential environmental impacts or nuisance:

· Covering stockpile of C&D material entirely by clean impervious sheet to reduce potential dust impact;

· Locating stockpiles to minimise potential visual impacts; and

· Minimizing land intake of stockpile areas as far as possible.

5.2.8 When disposing C&D material at a public fill reception facility, the material shall only consist of soil, rock, concrete, brick, cement plaster/mortar, inert building debris, aggregates and asphalt. The material shall be free from marine mud, household refuse, plastic, metals, industrial and chemical waste, animal and vegetable matter, and other material considered to be unsuitable by the Filling Supervisor.

Chemical Wastes

5.2.9 After use, chemical wastes (for example, cleaning fluids, solvents, lubrication oil and fuel) should be handled according to the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Spent chemicals should be collected by a licensed collector for disposal at the Chemical Waste Treatment Centre or other licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.

General Refuse

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

6. LANDSCAPE AND VISUAL

6.1. Introduction

6.1.1 It is recommended that EM&A for landscape and visual resources is undertaken during the detailed design stage as well as the construction and operational phases of the project.

6.1.2 The key landscape resources and visual sensitive receivers are shown in Figures of EIA report, mitigation measures are shown in Figure 6.1.

6.2. Monitoring Details

6.2.1 The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that they are fully realised and that potential conflicts between the proposed landscape measures and any other project works and operational requirements are resolved at the earliest possible date and without compromise to the intention of the mitigation measures.

Design

6.2.2 The incorporation of design guidelines proposed within the EIA during the detailed design stage should be checked to ensure that they fulfil the intentions of the mitigation measures. Any design changes should also be checked.

Construction & Establishment Period

6.2.3 Implementation of the mitigation measures recommended by the EIA should be monitored throughout the construction phase site audit programme to ensure compliance with the intended aims of the measures.

6.2.4 The implementation of landscape works including tree transplanting and preservation works, and subsequent maintenance during the 12-month establishment period must be supervised by a competent landscape architect (employed by the Contractor). Measures undertaken by both the Contractor and Landscape Contractor shall be audited by the ET on a regular basis to ensure compliance with the intended aims of the measures. Moreover, detailed tree preservation, transplanting and compensatory planting proposals shall be submitted to relevant government departments for approval in accordance with ET WBTC no. 3/2006.

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

OVT Protection

6.2.6 Appropriate protection measures for OVTs have been recommended in the EIA Report. Under the study, the residual impacts on OVTs are considered as insubstantial with mitigation measures as no OVTs will be affected. The crown and root of OVTs will be preserved in-situ.

6.2.7 The proposed emergency exit in front of the Miramar Shopping Centre has been designed to place well away from the OVT in the roadside planter. It will be located at approximately 12m from the trunk of the OVT and approximately 5m away from its drip line. Nevertheless, appropriate protection measures for the OVT as recommended by Professor C.Y. Jim of the University of Hong Kong are proposed. Extra care will be taken to ensure that the OVT will not be unduly affected.

· Measures stipulated in the ETWB TCW No. 29/ 2004 will be followed as appropriate.

· The area will be instituted to guard against intrusion into Cordon Zone (CZ).

· The CZ should not be allowed to become a resting place, eating or recreational space for workers.

· No construction crews, vehicles or equipment should be allowed for enter the CZ.

· Construction materials and equipment should not be stored inside the CZ.

· Construction wastewater or effluent should not flow into the CZ.

· Exhaust fames and hot air emanated by construction machines should not drift into the tree crown.

· The existing concrete paving and soil within CZ should be kept intact to avoid disturbing the soil and the enclosed roots.

· As far as practicable, construction equipment with a short rig or body should be employed to avoid conflicts with the tree crown.

· Grouting will be carried out in a controlled and effective manner for the protection of tree roots along Nathan Road.

· A programme of close monitoring of tree condition before (baseline evaluation), during and for one year after completion of construction, shall be instituted at regular intervals.

· Induction seminar will be organized to coach construction workers and their supervisors of the need and the precautions to protect the tree.

· Precautionary measures, such as site inspection on tree condition, shall be conducted to protect the trees during the construction stage.

6.3. Mitigation Measures

6.3.1 A series on mitigation measures as recommended in the EIA Report are summarised below:

2.9.3 The implementation schedule for the recommended construction air quality impact mitigation measures is presented in Appendix B.

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.

3.2. Construction Noise Parameters

3.2.2 A sample data record sheet based on the one presented in EM&A Guidelines for Development Projects in Hong Kong is shown in Appendix C. The ET may modify the data record sheet for this EM&A programme.

3.3. Construction Monitoring Equipment

3.3.2 Noise measurements should not be made in the presence of fog, rain, wind with a steady speed exceeding 5ms-1 or wind with gusts exceeding 10ms-1.

3.3.3 The ET is responsible for providing sufficient and suitable noise measuring equipment and associated instrumentation for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

3.4. Construction Noise Monitoring Locations

3.4.1 Based on the EIA Report, the locations designated for construction noise monitoring are listed in Table 3.1 and illustrated in Figure 2.1.

3.5. Construction Noise Baseline Monitoring

3.5.1 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 2 weeks.

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

3.6. Construction Noise Impact Monitoring

3.6.2 If construction works are extended to include works during the hours of 1900 – 0700 as well as public holidays and Sundays, applicable construction noise permits (CNP) under NCO shall be obtained by the Contractor.

3.7.1 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.

3.8.1 The EIA report indicated some noise exceedance for limited periods of time. Therefore, appropriate mitigation measures and good site practices are recommended to be properly implemented. The mitigation measures recommended in the EIA report are summarised below:

3.8.2 A community liaison channel will be set up to handle any public enquiry and complaint.

3.8.3 The implementation schedule for the recommended mitigation measures is presented in Appendix B.

3.9. Operation Ventilation Noise

3.9.2 However, it is still recommended that the following noise reduction measures shall be considered as far as practicable during construction:

4.1. Introduction

4.2. Site Inspection

4.2.1 Regular site inspection should be conducted to inspect the construction activities and works areas in order to ensure the recommended mitigation measures are properly implemented, which is adequate for protection of water resources.

4.3. Mitigation Measures

4.3.1 Mitigation measures recommended for the construction phase of the Project are summarized below. The implementation schedule of the recommended water quality mitigation measures is presented in Appendix B.

4.3.2 Construction runoff and site drainage should be prevented or minimized in accordance with the guidelines stipulated in ProPECC PN 1/94 “Construction Site Drainage”. The specified mitigation measures and practices include the following:

4.3.3 Underground works should be conducted sequentially to limit the amount of construction runoff generated from exposed areas during the wet season (April to September).

4.3.4 Uncontaminated discharge should pass through settlement tanks prior to off-site discharge.

4.3.5 The wastewater with a high concentration of SS should be treated (e.g. by settlement in tanks with sufficient retention time) on-site prior to off-site discharge. Oil interceptors would also be installed to remove the oil, lubricants and grease from the wastewater if required.

4.3.6 Temporary sanitary facilities, such as portable chemical toilets, should be employed on-site where necessary to handle sewage from the workforce. A licensed contractor would be responsible for appropriate disposal of waste matter and maintenance of these facilities.

4.3.7 Debris and rubbish generated on-site should be collected, handled and disposed of properly to avoid being flushed or blown by wind into the drainage culvert. Stockpiles of cement and other construction materials should be kept covered when not being used.

5.1. Introduction

5.2. Mitigation Measures

5.2.1 Mitigation measures for waste management as recommended in the EIA Report are summarised below. With the appropriate handling, storage and removal of waste arising during the construction works as defined below, the potential to cause adverse environmental impacts would be minimised.

5.2.3 Adverse impacts related to waste management are not expected to arise, provided that good site practices are strictly followed. Recommendations for good site practices during the construction activities include:

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

5.2.6 In addition to the above measures, specific mitigation measures are recommended below for the identified waste arisings to minimise environmental impacts during handling,

5.2.7 Within stockpile areas, the following measures should be taken to control potential environmental impacts or nuisance:

6.1. Introduction

6.1.1 It is recommended that EM&A for landscape and visual resources is undertaken during the detailed design stage as well as the construction and operational phases of the project.

6.1.2 The key landscape resources and visual sensitive receivers are shown in Figures of EIA report, mitigation measures are shown in Figure 6.1.

6.2. Monitoring Details

6.2.2 The incorporation of design guidelines proposed within the EIA during the detailed design stage should be checked to ensure that they fulfil the intentions of the mitigation measures. Any design changes should also be checked.

6.2.3 Implementation of the mitigation measures recommended by the EIA should be monitored throughout the construction phase site audit programme to ensure compliance with the intended aims of the measures.

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

6.2.6 Appropriate protection measures for OVTs have been recommended in the EIA Report. Under the study, the residual impacts on OVTs are considered as insubstantial with mitigation measures as no OVTs will be affected. The crown and root of OVTs will be preserved in-situ.

6.3. Mitigation Measures

6.3.1 A series on mitigation measures as recommended in the EIA Report are summarised below:

3.3.2 Noise measurements should not be made in the presence of fog, rain, wind with a steady speed exceeding 5ms^-1 or wind with gusts exceeding 10ms^-1.
