1.2 Project Description

1.2.1 The site is located in the eastern side of Kowloon to the south of the Eastern Harbour Crossing and is in an area of existing development. The site is bounded on the north and to the east by Cha Kwo Ling Road and existing development, to the south by Ko Fai Road and existing development and to the west by Victoria Harbour. Figure 1.1 shows the location of the existing Yau Tong Bay.

1.2.2 The reclamation site is partly zoned “Comprehensive Development Area (CDA)” on the current Cha Kwo Ling, Yau Tong, Lei Yue Mun Outline Zoning Plan No. S/K/15/13. A request for rezoning of Yau Tong Bay CDA was submitted by David C Lee Surveyors Ltd. on behalf of Main Wealth Development Ltd. on 1 August 1998 and approval in principle was given on 11 December 1998 by the MPC. The population of the development on the proposed CDA after rezoning is about 39,000 persons. Due to different options on the alignment of the Western Coast Road (WCR), there are two different sets of development options on the layout of the CDA – Minimised Reclamation Option (Figure 1.2a) and Full Reclamation Option (Figure 1.2b).

1.2.3 The construction works of Yau Tong Bay Development project will be carried out on the reclaimed land and the land formed by the demolition of existing building structures. The construction activities for reclamation are described in the Package 1 EIA report for Yau Tong Bay Reclamation.

1.2.4 The development will involve mainly the construction of infrastructures. It consists of the construction of residential towers, commercial towers, shopping arcade and eight numbers of primary and secondary schools. Foundation of building towers will be constructed once the reclaimed land is formed and settled to the required level.

1.2.5 The temporary sewage retention tank will be built during the first phase of development, which is anticipated to be within 2008 to 2009. The tank is an underground reinforced concrete structure. The estimated volume of the tank is about 2,712m³.

1.2.6 Laying of underground services and utilities, for instance, drainage and sewerage system, water supply pipeworks, communication and electric cables will be continued after the removal of surcharge for reclamation. Noise barrier within the development area will be erected along Cha Kwo Ling Road and Ko Fai Road simultaneously. After the completion of laying underground utilities, the internal road construction will be commenced.

1.3 Construction Programme

1.3.1 The anticipated the commencement date of the construction works for the development of all options is in October 2005. The overall construction period of the whole development will be approximately 10 years and the anticipated completion date would be in early 2016. The programme and phasing layout will be reviewed in the detailed design stage.

Air Monitoring Station 1 (AMS1)	Yau Tong Industrial City
Air Monitoring Station 2 (AMS2)	New School
Air Monitoring Station 3 (AMS3)	Cha Kwo Ling
Air Monitoring Station 4 (AMS4)	Yau Tong Estate

2.4.2 The status and locations of dust sensitive receivers may change after issuing this manual. If such cases exist, the ET shall propose updated monitoring locations and seek approval from ER and agreement from EPD on the proposal.

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

a) at the site boundary or such locations close to the major dust emission source;

b) close to the sensitive receptors; and

c) take into account the prevailing meteorological conditions.

2.4.4 The ET Leader shall agree with the ER on the position of the HVS for installation of the monitoring equipment. When positioning the samplers, the following points shall be noted:

a) a horizontal platform with appropriate support to secure the samplers against gusty wind should be provided;

b) no two samplers should be placed less than 2 meter apart;

c) 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;

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

e) a minimum of 2 metre separation from any supporting structure, measured horizontally is required;

f) no furnace or incinerator flue is nearby;

g) airflow around the sampler is unrestricted;

2.5 Baseline Monitoring

2.5.1 The ET Leader shall carry out baseline monitoring at all of the designated monitoring locations for at least 14 consecutive days prior to the commissioning of the construction works to obtain daily 24-hr TSP samples. 1-hr sampling shall also be done at least 3 times per day while the highest dust impact is expected.

2.5.2 During the baseline monitoring, there should not be any construction or dust generation activities in the vicinity of the monitoring stations. In case the baseline monitoring cannot be carried out at the designated monitoring locations during the baseline monitoring period, the ET Leader shall carry out the monitoring at alternative locations which can effectively represent the baseline conditions at the impact monitoring locations. The alternative baseline monitoring locations shall be approved by the EC and agreed with EPD.

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

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

2.6 Impact Monitoring

2.6.1 The ET Leader shall carry out impact monitoring during the course of the Works. For regular impact monitoring, the sampling frequency of at least once in every six-days, shall be strictly observed at all the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least three times in every six-days should be undertaken when the highest dust impact occurs.

2.6.2 The specific time to start and stop the 24-hour TSP monitoring shall be clearly defined for each location and be strictly followed by the operator.

2.6.3 In case of non-compliance with the air quality criteria, more frequent monitoring exercise, as specified in the following section, shall be conducted within 24 hours after the result is obtained. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified.

2.7 Event and Action Plan for Air Quality

2.7.1 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 24-hour TSP and 1-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 criteria occurs, the EC should shall be consulted and the ET, the ER and the Contractor shall undertake the relevant action in accordance with the Action Plan in Table 2.3.

2.8 Dust Mitigation Measures

2.8.1 The EIA report has recommended dust control and mitigation measures. The Contractor shall be responsible for the design and implementation of these measures. The recommended mitigation measures are listed as follows:-

General Site Management

· The Contractor shall at all time prevent dust nuisance as a result of construction activities. The air control system installed shall be operated whenever the plants in operation.

· Careful sitting of construction activities which generate substantial amount of dust can effectively reduce the overall impact.

· No free falling construction debris should be allowed; debris should be let down by hoist or enclosed tunnel to the ground.

· Frequent watering for particularly dust areas is an effective and most commonly adopted dust control method. The frequency of application in order to achieve effective dust control will depend upon local conditions such as rainfall, temperature, wind speed and humidity. It is important to avoid overwatering or allowing surface layer of material to become dried out such that sufficient adhesion can be maintained to percent dust emissions.

Vehicles and Unpaved Site Roads

· Regular watering should be employed with complete coverage during construction phase to reduce dust emission from unpaved roads.

· Speed controls for vehicles on unpaved site roads will be imposed and their movement should be confined to designed roadways within the site. Where feasible, routing of vehicles and positioning of construction plants should be at a maximum possible distances from sensitive receivers.

· All dusty vehicle loads transported to, from and between site locations should be covered by tarpaulin.

· Vehicle wheel and body washing stations should be established at exit points of site and public roads, combined with cleaning of public roads wherever necessary and practical.

Aggregate Storage and Handling

· When stockpiling of construction material or debris is inevitable, enclosed and covering storage can bring about reductions in dust emissions. The use of wind breaks may provide some protection and covering the material with tarpaulin will reduce dust emissions considerably. Watering is another dust control method most commonly employed in storage piles and handling operations. However, watering tends to have only a temporary effect on dust emissions with an efficiency up to 40%.

· Whenever possible, materials should be damped prior to handling. Handling procedures should be developed to cause minimal disturbance. If screening is available it will help to lower wind speed in the area and thus reduce dust generation.

2.8.2 If the above measures are not sufficient to restore the air quality to acceptable levels, upon the advice of ER/EC, the Contractor shall liaise with the ER/EC on some other mitigation measures, propose for approval, and implement the mitigation measures.

2.8.3 In addition, the Contractor should comply with the requirement as stipulated in the Air Pollution Control (Construction Dust) Regulation.

3. NOISE

3.1 Introduction

3.1.1 Although the construction noise assessment indicates that the predicted mitigated noise levels at all NSRs comply with the noise criterion, a limited amount of daytime noise monitoring for 30 active minutes on a bi-weekly basis shall be carried out during construction phase to ensure the construction complying with the EIAO-TM. Details of noise monitoring and recommendation on mitigation measures during construction phase are given in Sections 3.2.1 to 3.2.18.

3.1.2 Mitigation measures are recommended to mitigate the road traffic noise impact during the operational phase. Details are given in Sections 3.3.1 to 3.3.3.

3.2 Construction Phase

Noise Parameters

3.2.1 The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30min) shall be used as the monitoring parameter for the time period between 0700-1900 hours on normal weekdays. For all other time periods, Leq (5min) shall be employed for comparison with the NCO criteria. A sample data record sheet is shown in Appendix 3A for reference.

Monitoring Equipment

3.2.2 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 (IEC) publications 651:1979 (Type I) and 804:1985 (Type I) 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 1.0dB.

3.2.3 Noise measurements should not be made in accordance with standard acoustical principles and practices in relation to weather conditions.

3.2.4 The Engineer is responsible for the provision of the monitoring equipment. He shall ensure that sufficient noise measuring equipment and associated instrumentation are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.

Monitoring Locations

3.2.5 The noise monitoring shall be conducted at the identified monitoring stations as shown in Table 3.1 and Figure 3.1. The status and locations of noise sensitive receivers may change after issuing this manual. If such cases exist, the Engineer shall propose updated monitoring locations and seek agreement from EPD of the proposal.

Table 3.1 Noise Monitoring Locations

NSRs	Noise Monitoring Locations
RYTE2	Yau Tong Estate (Phase 2)
REHC2	Eastern Harbour Crossing Site (Phase 2)
RSCH2	New School at Yau Tong Estate (South)

3.2.6 When alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria:-

a) at locations close to the major site activities which are likely to have noise impacts;

b) close to the noise sensitive receivers (N.B. for the purposes of this section, any domestic premises, hotel, hostel, temporary housing accommodation, hospital, medical clinic, educational institution, place of public worship, library, court of law, performing art centre should be considered as noise sensitive receiver); and

c) for monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance to the occupants during monitoring.

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

Baseline Monitoring

3.2.8 Baseline monitoring shall be carried out in all of the identified monitoring stations for at least one consecutive weeks prior to the commissioning of the construction work for the purpose of determining the nature and ranges of natural variation.

Impact Monitoring of Construction Noise

3.2.9 Noise monitoring shall be carried out at all the designated monitoring station. The monitoring frequency shall depend on the scale of the construction activities. The following is an initial guide on the regular monitoring frequency for each station on a per bi-week basis when noise generating activities are underway:-

· one set of measurements between 0700-1900 hours on normal weekdays;

3.2.10 No night-time construction works are scheduled to be carried out in this project. If general construction works are necessary to be carried out during restricted hours, it will be controlled by CNP system under the NCO.

3.2.11 Noise monitoring shall be carried out at the monitoring station for RSCH2 during the school examination periods. The Engineer shall liaise with the college personnel and the Examination Authority to ascertain the exact dates and times of all examination periods during the course of the contract.

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

Noise Mitigation Measures

3.2.15 The results of the noise assessment of the EIA report has shown that some of the nearby NSRs will be affected by the construction of the Development, mitigation measures are given in the following to reduce the noise impact. The Contractor shall be responsible for the design and implementation of these measures.

3.2.16 The contractor should be requested to adopt the following mitigation measures:-

· Scheduling of work - The Contractor has to make the choice of the number and types of construction equipment taking into account the use of quiet plant while devising a feasible work programme.

· Siting of facilities - This includes minimizing noisy operations during examination periods; avoiding simultaneous operation of noisy equipment; retaining existing features that can act as a noise barrier until the last phase; and erecting, as early as possible, any new structures which will have the effect of screening noise sources. Such screens can reduce noise levels by 5dB(A) or more. Noisy equipment, such as emergency generators and water pumps, should always be sited as far as possible from noise sensitive receivers. Consideration should also be given to the use of structures such as site offices and stores as noise barriers.

· Movable noise barrier - A typical design being adopted extensively for local construction sites is a 3 m high wooden framed barrier with a small cantilevered upper portion infilled with marine ply of density no less than 20 kg/m²on a skid footing. It could provide up to 5 dB(A) attenuation if they are correctly positioned for static plant such as air compressors, drilling rigs, water pumps, generators and concrete pumps.

· Use of Quiet Powered Mechanical Equipment (PME) - The contractor should be requested, as far as possible, to use quiet PME, whose actual SWL is less than the value specified in GW-TM. This is one of the most effective measures and is increasingly practicable because of the availability of quiet equipment. Examples of SWLs for specific silenced PME, which are generally available in Hong Kong, are given in the following Table 3.4.

3.2.17 Good site practice and noise management can considerably reduce the impact of the construction sites’ activities on nearby NSRs. The following measures should be followed 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 trucks) 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, should, where possible, be orientated so that the noise is directed away from nearby NSRs;

· silencers or mufflers on construction equipment should be utilised and should be properly maintained during the construction period;

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

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

3.2.18 The implementation schedule for noise control is given in Appendix 3B.

3.3 Operational Phase

3.3.1 The noise assessment results of the EIA report has shown that the NSRs in the Development will be affected by the road traffic in the vicinity, mitigation measures are given in the following to further reduce the road traffic noise. The proponent shall be responsible for the implementation of these measures.

3.3.2 The following mitigation measures are recommended:-

Alternative land use arrangement and siting

· For all development options, the non-domestic components have been arranged to the perimeter of the site in order to minimize the impact of traffic noise to the residential units, e.g. office/retail complex and schools were located near Cha Kwo Ling, while residential towers facing Ko Fai Road have been setback 30m from the road. The land use arrangement as shown is considered to be the best option.

Setback of Residential Towers

· The residential towers have incorporated setback distances of minimum 30m from the southern site boundary facing Ko Fai Road and greater than 30m from Western Coast Road for the WCR Coastal Option. For the towers located at the YTML lots 73-74 and 25-27, the design has incorporated maximum setback distances from Cha Kwo Ling Road. It is not possible to incorporate additional setback distances such that the noise impacts will be further reduced significantly.

Setback and Orientation of Schools

· The schools have incorporated maximum setback distances from Cha Kwo Ling Road in order to reduce the traffic noise impact. The windows of the classrooms are mostly perpendicular to the road instead of having a direct facing, thus helping to minimise the traffic noise impact to the schools.

Building Orientation and Building Design

· The present building arrangement proposal is considered as one of the best options from urban design and architectural design point of view. It has minimized the visual impact of the residential towers and overlooking problem of adjacent flats.

· The office towers and the shopping arcade, together with the schools, will effectively screen the residential towers from the traffic noise impact from Cha Kwo Ling Road. The majority of the NSRs in the towers will be subject to noise levels within the 70dB(A) criterion.

Refined Scheme

· In order to minimize the traffic noise impact caused by the Western Coast Road (WCR) to the schools of the Development, a Refined Scheme with schools relocated away from the WCR has been developed and assessed with WCR Tunnel Option (Minimised Reclamation) and WCR Coastal Option (Full Reclamation).

· Results of noise assessment indicate that the relocated schools will be subject to insignificant traffic noise levels of not greater than 60dB(A) and that the residential towers will not be adversely affected due to adequate setback from the WCR.

Podium Edge Noise Barriers

· The 5m high noise barrier will be required to be erected at the podium edge facing Ko Fai Road and Cha Kwo Ling Road (Figures 3.2a – 3.2h). The 5m high podium edge noise barrier will effectively screen the residential towers from the traffic noise impact due to Ko Fai Road and Cha Kwo Ling Road.

Purpose-Built Noise Barriers

· The effectiveness of erecting noise barriers along Cha Kwo Ling Road has been investigated. Results indicate that 5m high roadside noise barriers will significantly reduce the noise levels at the schools and that at low levels of the residential towers closed to Cha Kwo Ling Road (Figures 3.2a - 3.2h).

Provision of Upgraded Glazing and Air-conditioners for Residential Towers

· As a last resort to reduce the noise impacts on the occupants of the residential Development, window type I (as per EIAO-TM^[3]) with glazing comprising minimum 6mm thick glass pane and well gasketted seal will be installed to the noise sensitive areas including bedrooms, living rooms and dining rooms of the affected residential flats (Figures 3.2a – 3.2h).

· It is recommended to provide air-conditioners to all noise sensitive areas of the affected residential flats so that the occupants will not solely rely on open windows for ventilation and that the adverse noise impact caused by the road traffic will be effectively reduced (Figures 3.2a – 3.2h).

Provision of Upgraded Glazing and Air-conditioners for Schools

· Upgraded window glazing and air-conditioners should be provided to the affected noise-sensitive rooms of the schools, in addition to the recommended roadside noise barriers along Cha Kwo Ling Road. Window type I (as per EIAO-TM^[^3]) with 6mm thick glass pane and well gasketted seals will be provided.

The necessity of the Proposed WCR Semi-Enclosure & Barriers for WCR Coastal Option

· Additional calculations have been performed to assess the WCR noise impacts if other means of noise reduction are to be taken. It is not considered viable to construct noise barriers with a practical height within the western site boundary for screening the WCR noise as the towers are of at least 39- storey high and the WCR is elevated. Further significant setback of the towers will not be possible with the site fully utilised by the proposed towers and schools.

· Based on the results reported in Section 5.6 of the EIA report, the percentage of exceedence of the residential development with semi-enclosure for the WCR is 2%. The proposed WCR semi-enclosure is essential for the Development as an unacceptably high 9% exceedence will result for the scenario without WCR semi-enclosure.

Decking Over and Extended Podium

· As all the surrounding roads are existing and are lying outside the site boundary, decking over these roads is considered not viable. However, in order to screen off part of the traffic noise, one storey podium has been proposed and extended up to the site boundary along Ko Fai Road and Cha Kwo Ling Road together with other noise mitigation measures including barriers, setback distance, non-openable windows and podium design (as indicated in Figures 3.2a to 3.2h).

3.4 Noise Mitigation Measures for Potential I/R Interface Problems

3.4.1 The noise assessment results of the EIA report has shown that the NSRs in the Development will be affected by the industrial noise from the remaining lots, mitigation measures are given in the following to further reduce the noise impact. The proponent shall be responsible for the implementation of these measures.

3.4.2 The following mitigation measures are recommended:-

Careful layout

· The layout plans for WCR Coastal and Tunnel Options have been optimised so that the industrial premises will cause the minimum impact to residential blocks. Noise tolerant buildings such as office and shopping arcade will be provided as screens for YTML lots 73-74 and 25-27 so that the schools and residential towers will keep maximum setback distances from the industrial lots (Figures 3.2a & 3.2h).

Buffer Zone

· Temporary open space will be provided as buffer zone to maximise the setback distances from the industrial lots (Figures 3.2a & 3.2h).

Noise tolerant building design

· Noise tolerant building design has been employed for blocks located close to the industrial lots (Figures 3.2b & 3.2e)

Use of Noise tolerant structure to provide noise buffer

· The Clubhouse, which will be provided with central A/C and adequate glazing systems, will be noise-tolerant and serving as a noise buffer to Towers 36 and 37.

Design of tall podium and parapet as additional screen

· The shopping arcades will provide 15m high podiums with useful noise screening for protecting the schools and residential towers from the industrial lots YTML 1, 2-4, 25, 26 & 27.

· A 5m high podium will be employed such that the flats will be set back as much as practicable from the industrial lots. The use of a 1.2m high podium edge parapet will give an additional noise screening to reduce the industrial noise impact to the worst-affected flats at lower floors.

Use of tall noise barriers

· Tall noise barriers with a practical height of 8m will be erected at suitable locations around the industrial lots, supplementing the podium deck in screening the industrial noise from affecting the worst-affected flats on the lower floors (Figures 3.2b and 3.2e).

Provision made for upgraded glazing and A/C units for flats

· In order to reduce the external traffic noise impact on the occupants of the residential Development, upgraded glazing, i.e. window type I (as per EIA-TM^[3], Annex 5 of Table 2) with glazing comprising minimum 6 mm thick glass pane and well gasketted seal will be installed to the noise sensitive areas including bedrooms, living rooms and dining rooms of the affected flats. In addition, air-conditioners will be provided to all noise sensitive rooms of the flats so that the occupants will not solely rely on open windows for ventilation and that the adverse noise impact caused by external noise sources will be effectively reduced.

3.4.3 The implementation schedule for proposed mitigation measures is given in Appendix 3B.

4. WATER QUALITY

4.1 Introduction

4.1.1 The EIA has recommended mitigation measures. Each Contractor shall be responsible for the design and implementation of these measures, where appropriate. The following is a summary of the recommended measures.

4.2 Construction Phase

Good Site Practices to Minimise Impacts from Site Runoff

4.2.1 The good site practices outlined in ProPECC PN 1/94 “Construction Site Drainage" should be followed as far as practicable in order to minimise surface runoff and the chance of erosion, and also to retain and reduce any suspended solids prior to discharge. These practices include, inter alia, the following items:

· Provision of perimeter channels to intercept storm-runoff from outside the site. These should be constructed in advance of site formation works and earthworks.

· Sediment removal facilities such as sand traps, silt traps and sedimentation tanks should be provided to remove particles from run-off. These facilities should be properly and regularly maintained. The solids removed from these facilities during maintenance desilting should be disposed of to landfill.

· Programming of the works to minimise soil excavation works during rainy seasons.

· Exposed soil surface should be protected by shotcrete or hydroseeding as soon as possible to reduce the potential for soil erosion.

· Temporary access roads should be protected by crushed gravel and exposed slope surfaces should be protected when rainstorms are likely.

· Trench excavation should be avoided in the wet season, and if necessary, these should be excavated and backfilled in short sections.

· Open stockpiles of construction materials on site should be covered with tarpaulin or similar fabric during rainstorms.

Wastewater Arising from Workforce

4.2.2 Septic tanks or chemical toilets should be employed as far as practicable. Grease traps should also be provided for wastewater generated from canteens. Any such treatment facilities should be frequently maintained to ensure proper function. Production water should be recycled to minimise the wastewater discharge, where possible.

Accidental Spillage of Hazardous Materials

4.2.3 Potential impacts from chemical spillages can be considerably reduced by implementation of proper storage and handling procedures. Chemicals stored in tanks should be surrounded by bunding that can contain at least the volume of the tank and a free-board, sumps and oil interceptors should be provided. Bunded areas should be isolated from the stormwater drains and have an impermeable base or membrane liner if the ground is porous. Where possible, chemicals should be handled and used in areas appropriately equipped to control these discharges.

4.2.4 The service shop and maintenance facility should also be located on hard standings within a bunded area with sumps and oil interceptors.

4.2.5 Waste fuel and oil collected from the interception system should be disposed off-site at approved locations. This will either be for oil recovery or disposal at the Government Chemical Waste Treatment Facility.

4.2.6 A strategy should be developed for dealing with chemical spills, based on manufacturers’ recommendations. As for fuel spills, clean-up procedures should involve the use of absorbents and under no circumstances should spilled materials be washed down into storm drains or into the Victoria Harbour.

4.2.7 The implementation schedule for water pollution control is given in Appendix 4A.

4.2.8 During the site inspections as described in Section 7 of this Manual, the ET Leader shall pay special attention to the issues relating to water quality as described above, and check whether the Contractor has followed the relevant contract specifications and the procedures specified under the laws of Hong Kong. Stringent control and audit will be necessary to ensure that effective waste management practices and correct storage, transportation and disposal requirements for the various waste materials are being implemented.

4.3 Operational Phase

4.3.1 Surface runoff generated from the proposed development during the operational phase should be routed via sedimentation tanks or silt traps to minimise pollution load to the Victoria Harbour.

4.4 Water Quality Monitoring

4.4.1 Upon completion of all marine-based construction activities, a post-project monitoring exercise on water quality shall be carried out for 4 weeks in the same manner as the impact monitoring, plus monitoring of ammoniacal nitrogen and E. coli. The necessity of additional 6-month post-project water quality monitoring will be subject to the results obtained after the 4-week monitoring period at the Cha Kwo Ling Saltwater Pumping Station intake in order to address the concern from Water Supplies Department (WSD) on the possible deterioration in water quality after the completion of the reclamation. For other sensitive receivers, a 4-week post-project monitoring period will be adequate. Whenever the proposed mitigation measures failed to maintain the water quality within the WSD’s WQOs, further mitigation measures should be proposed and implemented. If further mitigation measures are still found to be ineffective, remedial actions (such as relocation of the pumping station) should be proposed and implemented. Details of monitoring are provided in the EM&A Manual of the Yau Tong Bay Development, Reclamation of Yau Tong Bay, Environmental Impact Assessment Study.

5. WASTE MANAGEMENT

5.1 Introduction

5.1.1 Waste management will be the contractor’s responsibility to ensure that all wastes produced during the construction of the proposed YTB development are handled, stored and disposed of in accordance with good waste management practices and EPD’s regulations and requirements.

5.1.2 Waste materials generated during construction activities, such as construction and demolition (C&D) materials, chemical wastes and general refuse from the workforce, are recommended to be audited at regular intervals (at least monthly) to ensure that proper storage, transportation and disposal practices are being implemented. This monitoring of waste management practices will ensure that these solid and liquid wastes generated during construction are not disposed into the surrounding marine waters. The Contractor will be responsible for the implementation of any mitigation measures to minimise waste or redress problems arising from the waste materials.

5.2 Waste Control and Mitigation Measures

5.2.1 Mitigation measures for waste management are summarised below. With the appropriate handling, storage and removal of waste arisings during the construction of the proposed YTB comprehensive development as defined below, the potential to cause adverse environmental impacts will be minimized. The implementation schedule of recommended mitigation measures for waste control is presented in Appendix 5A.

Good Site Practice and Waste Reduction Measures

5.2.2 In order to minimize the potential for adverse impacts on the environment, it is recommended that good site practices and waste reduction measures be adhered to, as follows:

· Nomination of an approved personnel, 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 handling procedures.

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

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

· Separation of chemical wastes for special handling and appropriate treatment at the Chemical Waste Treatment Facility.

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

5.2.3 A trip-ticket system should be included as one of the contractual requirements and implemented by the Environmental Team so as to monitor the disposal of C&D material and solid wastes at public filling areas and landfills, and to control fly-tipping. An Independent Checker (Environment) should be responsible for auditing the result of the system.

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

· 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.

· To encourage collection of aluminum cans by individual collectors, separate labeled bins should be provided to segregate this waste from other general refuse generated by the workforce.

· Any unused chemicals or those with remaining functional capacity should be recycled.

· Maximizing the use of reusable steel formwork and metal site hoarding to reduce the amount of C&D material;

· Prior to disposal of C&D waste, it is recommended that wood, steel and other metals be separated for re-use and/or recycling to minimise the quantity of waste to be disposed of to landfill.

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

· Plan and stock construction materials carefully to minimize amount of waste generated and avoid unnecessary generation of waste.

5.2.5 A recording system for the amount of wastes generated, recycled and disposed (including the disposal sites) should be proposed. Quantities could be determined by weighing each load or other suitable methods.

5.2.6 In addition to the above good site practices and waste reduction measures, specific mitigation measures are recommended below for the identified waste arisings to minimize environmental impacts during the handling, transportation and disposal of these wastes.

Construction and Demolition Material

5.2.7 In order to minimize the impact resulting from collection and transportation of construction and demolition material for off-site disposal, on-site waste separation, processing and storage facilities are recommended. Construction and demolition material should be separated on-site into three categories: (i) public fill, the inert portion of the material, which should be re-used on-site or disposed of at a public filling area (e.g. concrete, brick, rock and soil); (ii) the non-inert portion of the material (i.e. C&D waste) which can be re-used and/or recycled (e.g. wood, plastic, steel and other metals); (iii) the non-inert portion of the material which cannot be re-used and/or recycled which would require landfill disposal.

5.2.8 An on-site waste separation facility should be provided. The facility would be used to sort and process material generated from the construction activities. The sorting process should be carefully monitored to avoid mixing of the three categories of waste material as described above. It is recommended that on-site waste separation of construction wastes should be conducted as far as possible in order to minimize the amount of solid waste to be disposed of at the landfills. Records of quantities of waste generated, re-used, recycled and disposed (including locations should be properly kept.

Maintenance and Chemical Waste

5.2.9 Chemical waste produced from the construction activities should be handled according to the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes and disposed of by a licenced contractor at CWTF.

5.2.10 In addition, mitigation measures must be adopted to prevent the uncontrolled disposal of chemical and hazardous waste into the air, soil and waters:

· Drainage serving an open oil or petrol filling point or from vehicle and plant servicing areas shall be connected to the site drainage system via a petrol/oil interceptor with storm water bypass.

· Proper operational maintenance and inspection programme for plant and equipment should be carried out to minimize problems from leakage and accidental spillages of oils and petrol. Any such leakages or spillage shall be contained and cleaned up immediately.

5.2.11 Where tanks are to be emptied or removed, precautionary measures should be taken to avoid the spillage of any petroleum products which may cause contamination to the ground. Any contaminated materials such as absorbent or cleaning materials should be disposed of properly.

General Site Wastes

5.2.12 A collection area should be provided where waste can be stored and loaded prior to removal from site. An enclosed and covered area is preferred to reduce the occurrence of 'wind blow' light material. If an open area is unavoidable for the storage or loading/unloading of wastes, then the area should be bunded and all the polluted surface run-off collected within this area should be diverted into sewers.

Workforce Wastes

5.2.13 Suitable collection sites around site offices and canteen will be required. It is recommended that for environmental hygiene reasons and to minimise odour, putrescible wastes are not stored for a period exceeding 48 hours, however, removal every 24 hours is preferable.

5.2.14 Table 5.1 provides a summary of waste handling methods for different types of waste.

5.2.15 During operational phase, refuse collection chambers (RCC) should be provided for the residential development as well as the office/retail development.

5.2.16 The Contractor shall pay attention to the Waste Disposal Ordinance, the Dumping at Sea Ordinance, the Public Health and Municipal Services Ordinance and the Water Pollution Control Ordinance, and carry out the appropriate waste management work. The relevant licence/permit, such as the chemical waste producer registration, etc. shall be obtained. The Contractor shall refer to the relevant booklets issued by EPD when applying for the licence/permit.

5.2.17 During the site inspections as described in Section 7.1 of this Manual, the ET Leader shall pay special attention to the issues relating to waste management, and check whether the Contractor has followed the relevant contract specifications and the procedures specified under the laws of Hong Kong. Stringent control and audit will be necessary to ensure that effective waste management practices and correct storage, transportation and disposal requirements for the various waste materials are being implemented.

· Integrate design of the building element with landscape garden

6.4.3 The implementation schedule for the proposed mitigation measures is given in Appendix 6A.

7. SITE ENVIRONMENTAL AUDIT

7.1 Site Inspections

7.1.1 Site inspections provide 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. The site inspection is one of the most effective tools to enforce the environmental protection requirements at the works area.

7.1.2 The ET Leader shall be responsible for formulating the environmental site inspection, the deficiency and action reporting system, and for carrying out the site inspection works. Within 21 days of the construction contract commencement he shall submit a proposal for site inspection and deficiency and action reporting procedures to the Contractor for agreement, and to the ER for approval. The ET’s proposal for rectification would be made known to the IC(E).

7.1.3 Regular site inspections shall be carried out at least once per week. 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 situation outside the works area which is likely to be affected, directly or indirectly, by the site activities. The ET Leader shall make reference to the following information in conducting the inspection:

(i) EIA recommendations on environmental protection and pollution control mitigation measures;

(ii) works progress and programme;

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

(v) relevant environmental protection and pollution control laws; and

(vi) previous site inspection results.

7.1.4 The Contractor shall keep the ET Leader updated with all relevant information on the construction contract necessary for him to carry out the site inspections. Inspection results and associated recommendations for improvements to the environmental protection and pollution control works shall be submitted to the IC(E) and the Contractor within 24 hours. 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 Leader, to report on any remedial measures subsequent to the site inspections.

7.1.5 Ad hoc site inspections shall also be carried out if significant environmental problems are identified. Inspections may also be required subsequent to receipt of an environmental complaint, or as part of the investigation work, as specified in the Action Plan for environmental monitoring and audit.

7.2 Compliance with Legal and Contractual Requirements

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

7.2.2 In order that the works are in compliance with the contractual requirements, all works method statements submitted by the Contractor to the ER for approval shall be sent to the ET Leader for vetting to see whether sufficient environmental protection and pollution control measures have been included. The implementation schedule of mitigation measures is summarised in Appendix 2B, 3B, 4A, 5A and 6A.

		General Site Management · The Contractor shall at all time prevent dust nuisance as a result of construction activities. The air control system installed shall be operated whenever the plants in operation. · Careful sitting of construction activities which generate substantial amount of dust can effectively reduce the overall impact. · No free falling construction debris should be allowed; debris should be let down by hoist or enclosed tunnel to the ground. · Frequent watering for particularly dust areas. The frequency of application in order to achieve effective dust control will depend upon local conditions such as rainfall, temperature, wind speed and humidity. It is important to avoid overwatering or allowing surface layer of material to become dried out such that sufficient adhesion can be maintained to percent dust emissions. · Follow mitigation measures as laid out in Air Pollution Control (Construction Dust) Regulation. Environmental Monitoring and Audit · EM&A exercise for dust monitoring should be conducted as detailed in the EM&A manual.

		Vehicles and Unpaved Site Roads · Regular watering should be employed with complete coverage during construction phase to reduce dust emission from unpaved roads. · Speed controls for vehicles on unpaved site roads and movement of vehicles should be confined to designed roadways within the site. · Where feasible, routing of vehicles and positioning of construction plants should be at a maximum possible distances from sensitive receivers. · All dusty vehicle loads transported to, from and between site locations should be covered by tarpaulin. · Vehicle wheel and body washing stations should be established at exit points of site and public roads, combined with cleaning of public roads wherever necessary and practical. Aggregate Storage and Handling · When stockpiling of construction material or debris is inevitable, materials should be enclose and covered up. · Provide wind breaks and covering the exposed material with tarpaulin. · Watering the storage piles and during aggregate handling operations. · Whenever possible, materials should be damped prior to handling. · Handling procedures should be developed to cause minimal disturbance. · Use screening lower wind speed in the site area and thus reduce dust generation.
