3 AIR QUALITY IMPACT ASSESSMENT 3.1 Introduction 3.1.1 This section presents the assessment of potential air quality impacts associated with the construction
and operation phases of the Project. Dust generated from construction activities is the primary concern during the construction phase. Recommendations for proper mitigation measures have also been made, where necessary, to minimize the potential construction air quality impacts. During operation phase, no pollution sources associated with the Project would be anticipated.
3.2 Assessment Criteria and Guidelines 3.2.1 The assessment is carried out in accordance with the relevant criteria and standards as specified in
the following legislation and guidelines for evaluating air quality impacts:
• Air Pollution Control Ordinance (APCO) (Cap. 311);
• Air Pollution Control (Construction Dust) Regulation;
• Air Pollution Control (Smoke) Regulation;
• Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation; and
• Hong Kong Planning Standards and Guidelines (HKPSG).
Air Quality Objectives (AQO) in Air Pollution Control Ordinance (APCO)
3.2.2 The principal legislation for the management of air quality is the APCO. It specifies AQOs which stipulate the statutory limits of air pollutants and the maximum allowable numbers of exceedance over specific periods.
3.2.3 The Air Pollution Control (Amendment) Ordinance 2021 (Commencement) Notice, which seeks to appoint January 1, 2022, as the day on which the Air Pollution Control (Amendment) Ordinance 2021 (the Amendment Ordinance) comes into operation, was approved by the Legislative Council on June 23, 2021. The Amendment Ordinance tightens three air quality objectives (AQOs), namely the 24-hour AQO for sulphur dioxide (SO2) and the annual and 24-hour AQOs of fine suspended particulates (FSP/PM2.5) stipulated in Schedule 5 to the Air Pollution Control Ordinance (APCO) (Cap. 311). The prevailing AQOs are listed in Table 3.1.

3.5 Evaluation of Air Quality Impact During Construction Phase 3.5.1 Construction dust will be the primary concern of air quality impact during construction phase. The
construction of the Project involves small-scale site formation, construction of superstructure and utilities installation. Thus, the dust emission generated from these small construction works area is anticipated to be minimal.
3.5.2 Appropriate dust control measure should be adopted as required under the Air Pollution Control (Construction Dust) Regulation. Dust impact could be effectively mitigated by inclusion of proper contracts clauses for dust minimization in the works contracts.
3.5.3 Given that the recommended dust control measures as detailed in Section 3.7 (e.g. regular and sufficient water spraying / enclosure of dusty activities, etc.) are implemented, no significant fugitive dust impact is envisaged during construction phase. Hence, insignificant dust impacts on the surrounding ASRs are anticipated.
3.6 Evaluation of Air Quality Impact During Operation Phase 3.6.1 There are expected of potential air quality impacts during operation phase due to vehicular emissions
from surrounding roads and underground PVP.
3.6.2 The road type of Po Yip Street, Hong Yip Street, Wang Yip Street East and Keung Yip Street should be classified as Local Distributors and 5m of buffer distances, measured from the road kerbs of the road, shall be provided for the fresh air intake and active recreational uses of the project. TD’s The confirmation of road type from TD is provided in Appendix 3.1. All air sensitive uses of the proposed development will be located outside the buffer zone as shown in Figure 3.3.

3.6.3 Based on the site survey on 7 June 2021, there is a chimney at Nin Jiom Centre and is located about 550m from site boundary. And there is no other chimney within 500m from the site boundary. Adverse air quality impact on and from the Project is not anticipated.
3.6.4 The design of underground carpark should follow the ProPECC PN 2/96 - Control of Air Pollution in Car Parks. Car park ventilation systems should be designed to meet the air quality guidelines stipulated in the ProPECC PN2/96. In addition, it is recommended that the location of the exhaustion outlet of the ventilation system should be located as far as possible from the nearby air sensitives uses to avoid any adverse air quality impact. Exhaust air should be discharged to the atmosphere in such a manner and at such a location as not to cause a nuisance to occupants in the building or of neighbouring buildings or to the public.
3.7 Mitigation Measures During Construction Phase 3.7.1 Relevant dust control practices as stipulated in the Air Pollution Control (Construction Dust)
Regulation are recommended to be adopted so as to minimize the construction dust impacts of the Project. These practices include:
i. Good Site Management
▪ Good site management is important to help reduce potential air quality impact down to an acceptable level. As a general guide, the Contractor should maintain high standards of housekeeping to prevent emissions of fugitive dust. Loading, unloading, handling and storage of raw materials, wastes or by-products should be carried out in a manner so as to minimise the release of visible dust emission. Any piles of materials accumulated on or around the work areas should be cleaned up regularly. Cleaning, repair and maintenance of

Page 11
all plant facilities within the work areas should be carried out in a manner minimising generation of fugitive dust emissions. The material should be handled properly to prevent fugitive dust emission before cleaning.
ii. Disturbed Parts of the Roads
▪ Main temporary access points should be paved with concrete, bituminous hardcore materials or metal plates and be kept clear of dusty materials; or
▪ Unpaved parts of the road should be sprayed with water or a dust suppression chemical so as to keep the entire road surface wet.
iii. Exposed Earth
▪ Exposed earth should be properly treated by compaction, hydroseeding, vegetation planting or seating with latex, vinyl, bitumen within six months after the last construction activity on the site or part of the site where the exposed earth lies.
iv. Loading, Unloading or Transfer of Dusty Materials
▪ All dusty materials should be sprayed with water immediately prior to any loading or transfer operation so as to keep the dusty material wet.
v. Debris Handling
▪ Any debris should be covered entirely by impervious sheeting or stored in a debris collection area sheltered on the top and the three sides.
▪ Before debris is dumped into a chute, water should be sprayed onto the debris so that it remains wet when it is dumped.
vi. Transport of Dusty Materials
▪ Vehicles used for transporting dusty materials/spoils should be covered with tarpaulin or similar material. The cover should extend over the edges of the sides and tailboards.
vii. Wheel washing
▪ Vehicle wheel washing facilities should be provided at each construction site exit. Immediately before leaving the construction site, every vehicle should be washed to remove any dusty materials from its body and wheels.
viii. Use of vehicles
▪ The speed of the trucks within the site should be controlled to about 10 km/hour in order to reduce adverse dust impacts and secure the safe movement around the site.
▪ Immediately before leaving the construction site, every vehicle should be washed to remove any dusty materials from its body and wheels.
▪ Where a vehicle leaving the construction site is carrying a load of dusty materials, the load should be covered entirely by clean impervious sheeting to ensure that the dusty materials do not leak from the vehicle.
ix. Site hoarding
▪ Where a site boundary adjoins a road, street, service lane or other area accessible to the public, hoarding of not less than 2.4 m high from ground level should be provided along the entire length of that portion of the site boundary except for a site entrance or exit.
3.7.2 With proper implementation of the recommended mitigation measures as well as the relevant control requirements stipulated in the Air Pollution Control (Construction Dust) Regulation, no adverse air quality impacts are anticipated during the construction phase.
3.7.3 Moreover, the requirements stipulated in the Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation will be followed to control potential emissions from any non-road mobile machinery during construction phase.
3.8 Mitigation Measures During Operation Phase 3.8.1 Sufficient buffer distances are provided between the corresponding roads and the air sensitive
uses. Therefore, no further mitigation measure is required.

4 NOISE IMPACT ASSESSMENT 4.1 Introduction 4.1.1 This section presents the assessment of potential noise impacts associated with the construction
and operation phases of the Project. Noise generated from various construction activities is the primary concern during construction phase. Recommendations for proper mitigation measures have been made, where necessary, to minimize the potential construction noise impacts. Potential fixed noise source within the Project area is identified and the associated noise impact is evaluated in this section.
4.2 Environmental Legislation, Standards and Guidelines Construction Phase
4.2.1 Legislation, Standards, Guidelines and Criteria relevant to the consideration of construction noise impact under this Study include the following:
• Noise Control Ordinance (NCO)
• Technical Memorandum (TM) on Noise from Construction Work other than Percussive Piling (TM-GW)
• TM on Noise from Percussive Piling (TM-PP)
• TM on Noise on Construction Work in Designated Areas (TM-DA);
• TM on Noise from Places other than Domestic Premises, Public Places or Construction Sites (TM-Places);
• ProPECC PN 2/93 Environmental Protection Department Practice Note for Professional Persons: Noise from Construction Activities – Non-statutory Controls
General Construction Activities during Non-Restricted Hours
4.2.2 ProPECC PN 2/93 provides assessment criteria as well as requirements relating to construction noise not currently controlled under the NCO. The Practice Note also provides information on noise abatement measures. Noise impacts arising from general construction activities other than percussive piling during the daytime period (07:00-19:00 hours on any day not being a Sunday or general holiday) would be assessed against the noise standards tabulated in Table 4.1 below. Practicable direct mitigation measures will be evaluated and exhausted to maximise the protection of NSRs.
Table 4.1 Noise Standards for Daytime Construction Activities
Noise Sensitive Uses 0700 to 1900 hours on any day not being a Sunday or general holiday, Leq(30 min), dB(A)
Dwellings 75
School 70 65 during examination
Note: The above noise standards apply to uses, which rely on opened windows for ventilation. The above standards shall be viewed as the maximum permissible noise levels assessed at 1 m from the external façade
General Construction Activities during Restricted Hours
4.2.3 The NCO also provides statutory control on general construction works during restricted hours (i.e. 1900 to 0700 hours (of the next day) from Monday to Saturday and at any time on Sundays or public holidays). The use of PME for construction works during restricted hours would require a CNP. The

TM-GW details the procedures adopted by EPD for assessing such application. The granting of a CNP is subject to conditions stated in the CNP and it may be revoked at any time for failure to comply with the permit conditions.
4.2.4 In addition to the general controls on the use of PME during restricted hours, the use of Specified Powered Mechanical Equipment (SPME) and the undertaking of PCW during the restricted hours in a designated area are controlled by the TM-DA. Construction plant or equipment classified as SPME under the TM-DA includes hand-held breakers, bulldozers, concrete lorry mixers, dump trucks and vibratory pokers. The PCW includes the erection or dismantling of formwork or scaffolding, hammering, loading, unloading or handling of rubble, wooden boards, steel bars, wood or scaffolding material, and the disposal of rubble through plastic chutes.
4.2.5 The TM-DA details the procedures that should generally be adopted by the Noise Control Authority for assessing the use of SPME during restricted hours and for determining whether a CNP would be issued.
4.2.6 Maximum noise levels from construction activities during restricted hours at affected Noise Sensitive Receivers (NSRs) are controlled under the TMs and shall not exceed the specified Acceptable Noise Levels (ANLs). These ANLs are stipulated in accordance with the Area Sensitivity Ratings (ASRs) established for the NSRs. The ANLs for construction works in Designated Areas are more stringent than those given in the TM-GW and summarized in Table 4.2.

It should be noted that noise from fixed noise sources is controlled under section 13 of the Noise Control Ordinance. Therefore, the ASRs and ANLs determined in this report shall not prejudice the Noise Control Authority’s discretion to determine noise impact due to fixed noise sources on the basis of prevailing legislation and practices being in force and taking account of contemporary conditions/ situations of adjoining land uses. The assessment of noise impacts due to fixed noise sources in this report shall not bind the Noise Control Authority in the context of law enforcement against any of the noise from fixed noise sources being assessed.
4.2.11 Noise from existing fixed noise sources is controlled under the TM-Places. To plan for a better environment, the HKPSG has specified the following requirements for the planned fixed noise sources, whichever is more stringent.
• 5dB(A) below the appropriate ANLs in the TM-Places; or
• the prevailing background noise levels (For quiet areas with level 5dB(A) below the ANL).
Baseline Condition
4.2.12 The existing ambient noise levels are mainly generated by traffic along Po Yip Street, Hong Yip Street and nearby local roads. Prevailing background noise measurements to investigate the prevailing background noise levels near the Project area will be conducted. Measurement locations are presented in Figure 4.1 and the measurement results are summarised in Table 4.6.

Noise Criteria for Planned Fixed Noise Sources
4.2.13 As stipulated in Chapter 9 “Environment” of the HKPSG, the noise standards of the planned fixed noise sources are (a) 5 dB(A) below the appropriate ANL as stipulated in the TM-Place, or (b) the prevailing background noise levels (for quiet areas with level 5 dB(A) below the ANL).
4.2.14 The planned fixed noise sources criteria to be adopted for the NSRs are dependent on the background noise measurement results. Should the measured prevailing background noise level be lower than the ANL by more than 5 dB(A), the background noise level would be adopted as the criteria. The noise criteria of the planned fixed noise sources are summarised in Table 4.7 below.

4.4 Construction Noise Impact Assessment 4.4.1 Identification of Noise Sources 4.4.1.1 The potential source of noise impact for construction of the Project would be the use of PME for
various activities, including small-scale site formation, non-percussive piling foundation, construction of superstructure and utilities installation in the Project site. PME likely to be used include hand-held breaker, excavator, concrete lorry mixer, air compressor, and generator etc. As confirmed by the Project Proponent, construction activities for the Project would only be carried out during non-restricted hours (0700 – 1900 hours) on normal working dates.

4.4.2 Evaluation of Noise Impact 4.4.2.1 The construction activities will be confined inside the small site area which is approximately 1.4
hectare in size. The number of PME is expected to be limited. Given that the small scale and limited extent of construction, the construction noise is anticipated to be minimal.
4.4.2.2 Construction noise impacts could be effectively mitigated by inclusion of proper contracts clauses for construction noise mitigation in the works contracts. Given that the recommended noise mitigation measures as detailed in Section 4.4.3 (e.g. scheduling noisy activities, use of silenced equipment / movable noise barrier, etc.) are implemented, the construction noise impact to the NSRs in the vicinity is anticipated to be insignificant. A quantitative construction noise impact assessment can be provided prior to development of the site.
4.4.3 Mitigation Measures 4.4.3.1 It is recommended that the following noise mitigation measures should be implemented to minimize
the construction noise impact, e.g. “Recommended Pollution Control Clauses for Construction Contracts” available on EPD’s website1. A noise control plan should be set up to ensure regular maintenance of all plant and equipment, reduce noise generation at source, and that appropriate silencing applications are in use based upon the best reasonable practice.
4.4.3.2 Typical noise mitigation measures include:
• good site practice to limit noise emission at source;
• scheduling of construction works outside school examination periods;
• use of silenced equipment;
• use of movable noise barrier;
• use of noise enclosure/ acoustic shed;
• reduction in the number of items of PME operation at any given time; and
• avoidance of works in restricted hours etc.
4.4.3.3 These mitigation measures can be enforced by specifying a construction noise control plan as part of the contract document.
Good Site Practice
4.4.3.4 Good site practice and noise management can significantly reduce the impact of site activities on nearby NSRs. The following package of measures should be followed while carrying out of the Project:
• only well-maintained plant to be operated on-site and plant should be serviced regularly during the works;
• machines and plant that may be in intermittent use to 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 to direct noise away from the NSRs;
• mobile plant should be sited as far away from NSRs as possible; and
• material stockpiles and other structures to be effectively utilised, where practicable, to screen noise from on-site construction activities.
Selection of Quieter Plant
4.4.3.5 The Contractor may be able to obtain particular models of plant that are quieter than the standards given in the GW-TM. This is one of the most effective measures and is increasingly practicable because of the availability of quiet equipment. Quiet plant is defined as Quality Powered Mechanical

Equipment (QPME) whose actual SWL is less than the value specified in GW-TM for the same piece of equipment.
Use of Movable Noise Barriers
4.4.3.6 Movable noise barriers can be very effective in screening noise from particular items of plant when implementing the Project. Noise barriers located along the active works area close to the noise generating component of a PME could produce at least 10 dB(A) screening for stationary plant and 5 dB(A) for mobile plant provided the direct line of sight between the PME and the NSRs is blocked.
Use of Noise Enclosure/ Acoustic Shed
4.4.3.7 The use of noise enclosure or acoustic shed is to cover stationary PME such as air compressor and generator. With the adoption of the noise enclosure, the PME could be completely screened, and noise reduction of 15 dB(A) can be achieved according to the EIAO Guidance Note No.9/2010. Noise barriers should be free of gaps and made of materials having a surface mass density in excess of 10 kg/m2. To improve the effectiveness of noise reduction, non-flammable absorptive lining can be adhered on the inner surface of the noise barriers. The barrier can be in the form of vertical or bend top barrier with an effective height to block the line of sight to NSRs.
4.5 Operational Noise Impact Assessment 4.5.1 Identification of Noise Sources
Road Traffic Noise
4.5.1.1 According to HKPSG Chapter 9: “Where opportunity arises and having due regard to the operational requirements, the siting of facilities such as bus depots, lorry parks or petrol filling stations etc, should take into account the potential locations of ingress/egress and the consequent noise disturbances due to traffic routings, particularly during sensitive hours. Consideration should also be given to adopting administrative controls so that the degree of noise disturbances can be further reduced.”
4.5.1.2 Based on current layout, the ingress/egress is located at Po Yip Street. The project proponent has considered to design the ingress/egress at different locations, but with the following site constraint.
• the southbound carriageway of Wang Yip Street East adjacent to the Application Site is dedicated for parking by franchised buses between 20:00 – 08:00 next day and hence the provision of a run-in/run-out along this road would reduce the parking area which is subject to agreement by relevant authority such as Transport Department.
• during daytime, there are frequent loading/unloading activities at the existing layby on Wang Yip Street East and the deletion of the layby for providing a run-in/run-out would reduce the loading/unloading facility which is highly required by the local business in the area.
4.5.1.3 To assess the traffic noise impact induced by the project, the basic noise levels of nearby roads, under the scenarios of “without project” and “with project” are estimated. Based on NSRs locations, traffic noises from Po Yip Street, Hong Yip Street and Tak Yip Street are major concerned. The predicted flow is at year 2041, i.e. 15 year after operation. The calculation of basic noise levels are under CRTN and are summarized in the below Table 4.9 and 4.10.

4.5.1.4 With reference to the results above, the difference of basic noise levels between “without project” and “with project” is ranged from 0.0 dB(A) and 0.9 dB(A). The traffic noise impact induced by the project would be considered insignificant.
4.5.1.5 The induced traffic would be limited to private vehicles by users of PVP. Given the limited parking spaces and minimal induced traffic, significant traffic noise impact from the Project is not anticipated.
Fixed Noise Source
4.5.1.6 Site visit was conducted on 7 June 2021. Chillers at Cumberland Presbyterian Church Yao Dao Secondary School and Chung Sing School were observed on the roof top of school. It is expected that the operation of these chillers are from 0700 to 1900. The location of existing fixed noise source is shown in Figure 4.4.
4.5.1.7 Since the exact quantities and types of plants in the development are subject to detailed design and the information is not available during the preparation of PER, the maximum allowable sound power level is estimated based on the site boundary and the nearest NSR as a conservative approach.
Figure 4.4 Locations of Existing Fixed Noise Sources
4.5.2 Assessment Methodology 4.5.2.1 The planned ventilation system for underground public vehicle park will be operated 24 hours. Thus,
the day and evening time criterion of 60 dB(A) and night time criterion of 50dB(A) (with area sensitivity rating “B”) are adopted to assess the worst-case scenario.
4.5.2.2 Standard acoustics principles will be adopted to predict the potential fixed noise source impacts at NSRs. The maximum allowable sound power level is estimated based on the site boundary and the nearest NSR as a conservative approach.
4.5.3 Evaluation of Noise Impact 4.5.3.1 For planned fixed noise sources, the maximum allowable total SWL of the proposed plant under
100% operation (worst-case scenario) will be predicted based on backward calculation of separation distance and relevant noise criteria. The maximum allowable total SWL is listed below.

4.5.3.2 The Contractor should consider both the acoustic and engineering requirement, choose quieter equipment as far as practicable and adopt mitigation measures if necessary. Acoustic silencer and noise enclosure could be considered as mitigation measure.
4.5.3.3 The maximum SWL should be implemented and refined during the detailed design stage of the Project by the Contractor/ future operator considering the exact design details of plants and the actual surrounding conditions. Any planned noise sensitive uses identified at later stage should also be incorporated and taken into consideration for the assessment.
4.5.3.4 With the adoption of the proposed maximum allowable SWLs, the noise impacts due to the operation of Project to the surrounding NSRs would comply with the relevant noise criteria. Therefore, significant fixed noise impact from the Project to the nearby NSRs is not anticipated.
4.5.3.5 The PER will be attached to Tender Document and the Contractor shall comply with relevant criteria. The Contractor may apply appropriate noise attenuation measures such as acoustic silencers, acoustic louvre or acoustic enclosure, etc. as practicable to ensure the stipulated maximum SWLs will not be exceeded. The future design and selection of the equipment shall also aim to reduce the effect of tonality at the NSRs as much as practicable. However, the Contractor shall also take into account the latest available information at time of detailed design to review and update the maximum allowable SWL as appropriate. Meanwhile, fixed noise commissioning test prior to operation to ensure compliance with noise criteria in HKPSG in the Tender Document is also considered. Recommendations on mitigation of fixed noise sources impact are provided in Section 4.5.4.
4.5.4 Mitigation of Fixed Noise Sources Impact 4.5.4.1 For the proposed noise sources which are located near to NSRs, the following tentative noise
mitigation measures are considered:
• All the noisy plants should be installed within plant room or with acoustic enclosure;
• Proper selection of quiet plant aiming to reduce the tonality at NSRs;
• Installation of silencer / acoustic enclosure / acoustic louvre for the exhaust of ventilation system;
• Openings of ventilation systems should be located away from NSRs as far as practicable and oriented away from the NSRs; and
• Installation of absorptive noise barrier (with density of absorption material of 48kg/m3) for the aerator which would duly shield the engine and other noisy parts of the aerator as far as practicable.
4.5.4.2 The feasibility, practicability, programming and effectiveness of the above mitigation measures have been reviewed by engineer.

5 WATER QUALITY IMPACT ASSESSMENT
5.1 Introduction 5.1.1 This section presents the assessment of potential water quality impact associated with the
construction and operation phases of the Project. Recommendations for mitigation measures have been made, where necessary, to minimize the potential water quality impacts. During operation phase, the Project is unlikely to produce any adverse water quality impact.
5.2 Environmental Legislation, Standards and Guidelines 5.2.1 Relevant legislations, standards and guidelines governing water quality in Hong Kong include the
following:
• Water Pollution Control Ordinance (WPCO) Cap. 358
• Technical Memorandum on Standards for Effluents Discharged into Drainage and Sewerage Systems, Inland and Coastal Waters
• Practice Note for Professional Persons on Construction Site Drainage (ProPECC PN 1/94)
• Practice Note for Professional Persons on Drainage Plans (ProPECC PN 5/93)
Water Pollution Control Ordinance (WPCO)
5.2.2 The Water Pollution Control Ordinance (WPCO) (Cap. 358) provides the statutory framework for the protection and control of water quality in Hong Kong. According to the WPCO and its subsidiary legislations, Hong Kong waters are divided into 10 major Water Control Zones (WCZs) and 4 supplementary water control zones. Water Quality Objectives (WQOs) were established to protect the beneficial uses of water quality in WCZs and specific WQOs are applied to each WCZ. The study area for this water quality impact assessment covers Deep Bay WCZ. Based on Statement of Water Quality Objectives (Deep Bay Water Control Zone) , the corresponding marine WQOs are listed in Table 5.1.

5.5 Identification and Evaluation of Impact 5.5.1 Construction Phase 5.5.1.1 The sources of potential water quality impacts are identified as follow:
Construction Site Runoff
5.5.1.2 The surface runoff from construction works areas may contain increased loads of suspended solids (SS) and contaminants. Potential sources of pollution from construction site drainage include:
• Runoff and erosion from site surfaces, drainage channels, demolition works, earth working areas and stockpiles;
• Release of any bentonite slurries, concrete washings and other grouting activities;
• Wash water from dust suppression spray facilities; and
• Fuel, oil, solvents and lubricants from maintenance of mechanical equipment.
5.5.1.3 Sediment laden runoff particularly from works areas subjected to excavation or earth works, if uncontrolled, may cause increased levels of suspended solids and pollutants entering the stormwater drainage system and into the marine environment.
5.5.1.4 Mitigation measures and good site practices outlined in ProPECC PN 1/94 and listed in Section 5.6 should be implemented to control construction site runoff and drainage from the works area. The Contractor would also be required to apply for a discharge license under the WPCO. With implementation of the recommended mitigation measures along with compliance of the effluent standards set under TM-DSS, construction site runoff can be effectively controlled, and adverse impacts to storm drains or the marine environment is not anticipated.
General Construction Activities
5.5.1.5 On-site construction activities may result in water pollution from uncontrolled discharge of debris and rubbish such as packaging, construction materials, chemicals and refuse. Good construction and site management practices should be observed to ensure that litter, fuels and solvents do not enter the drainage system and marine environment.
5.5.1.6 With proper implementation of the good construction and site management practices mentioned in Section 5.6, water pollution arising from the general on-site construction activities can be prevented, and water quality impacts would not be anticipated.
Sewage Effluent from the Construction Workforce
5.5.1.7 Domestic sewage would be generated from the workforce during the construction phase. However, portable chemical toilets will be provided within the construction site. With implementation of mitigation measures suggested in Section 5.6, adverse water quality impact or impact on the identified sensitive receivers are not anticipated.
5.5.2 Operation Phase Sewage generated by the staff and visitors during operation phase
5.5.2.1 Sewage is expected to be generated from the facilities of proposed project and will eventually connect to the public sewerage. In this connection, effluent generated from the proposed development is deemed to be unlikely to endanger public health & safety to the sewerage system. Thus, no operational water quality impact from the Project is anticipated.
Runoff from road surfaces and paved areas
5.5.2.2 The runoff from road surfaces and paved areas is expected to be collected and discharged to the nearest public drainage system. There is no increment of paved area in the Project such that the site drainage plan will follow the existing drainage conditions. The adverse impacts to the water quality of the stormwater drainage system in the vicinity is not anticipated.

5.5.2.3 Meanwhile, the best practices in Practice Note for Professional Persons (ProPECC) PN 5/93 "Drainage Plans subject to Comment by the Environmental Protection Department" shall be followed.
5.6 Recommendation of Mitigation Measures 5.6.1 Construction Phase
Construction Site Runoff and Drainage
5.6.1.1 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 erosion, and also to retain and reduce any suspended solids prior to discharge. The following measures are recommended to protect water quality:
• At the start of site establishment, perimeter cut-off drains to direct off-site water around the site should be constructed with internal drainage works and erosion and sedimentation control facilities implemented. Channels (both temporary and permanent drainage pipes and culverts), earth bunds or sand bag barriers should be provided on site to direct stormwater 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. 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;
• The Contractor is required to obtain a wastewater discharge license under the WPCO prior to implementing any wastewater discharge;
• Programming of the works to minimise soil excavation works during rainy seasons;
• Exposed soil surface should be protected by shortcrete 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;
• 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. Particular attention should be paid to the control of silty surface runoff during storm events, especially for areas located near steep slopes.
• 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.
• Benonite slurries should be reconditioned and reused wherever practicable. Temporary storage locations (typically a properly closed warehouse) should be provided on site for any unused bentonite that needs to be transported away after all the related construction activities are completed. The requirements in ProPECC PN 1/94 should be adhered to in the handling and disposal of bentonite slurries.
General Construction Activities
5.6.1.2 Best Management Practices (BMPs) should be implemented at the construction site, including proper handling, sorting and storage of construction solid waste, debris and refuse generated on-site prior to disposal. General refuse and recyclable materials should be collected separately and stored in appropriately labelled bins and removed regularly to minimise the risk of windblown waste / debris discharging into the harbour.
Sewage Effluent from the Construction Workforce
5.6.1.3 The Contractor should provide temporary sanitary facilities, such as portable chemical toilets within the construction site to handle sewage from the workforce. The Contractor has the responsibility to

ensure that chemical toilets are used and properly maintained, and that licensed Contractors are employed to collect and dispose of the waste off-site at approved locations.
5.6.2 Operation Phase 5.6.2.1 During operation phase, sewage will be discharged to the existing sewerage network. No sewage
will be released to the environment without treatment.

6 WASTE MANAGEMENT IMPLICATIONS 6.1 Introduction 6.1.1 This section presents the assessment of potential waste arising from the construction and operation
activities of the Project and evaluates the potential environmental impacts that may result from the waste generated. Mitigation measures and good site practices, including waste handling, storage and disposal, are recommended with reference to applicable waste legislation and management guidelines.
6.2 Environmental Legislation, Standards and Guidelines 6.2.1 The following legislation relates to the handling, treatment and disposal of wastes in Hong Kong and
has been used in assessing potential impacts:
• Waste Disposal Ordinance (Cap. 354);
• Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C);
• Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap. 354N);
• Land (Miscellaneous Provisions) Ordinance (Cap. 28);
• Public Health and Municipal Services Ordinance (Cap. 132) - Public Cleansing and Prevention of Nuisances Regulation;
• Project Administration Handbook (PAH) for Civil Engineering Works (2020 Edition);
• WBTC No. 12/2000, Fill Management;
• ETWB TC(W) No. 19/2005, Environmental Management on Construction Sites;
• DEVB TC(W) No. 6/2010, Trip Ticket System for Disposal of Construction and Demolition Materials; and
• CEDD TC No. 11/2019, Management of Construction and Demolition Materials.
Waste Disposal Ordinance (Cap. 354)
6.2.2 The Waste Disposal Ordinance (WDO) prohibits any unauthorised disposal of wastes. Construction waste, defined under Cap. 354N of the WDO, refers to a substance, matter or thing which is generated from construction works. It includes all abandoned materials, whether processed or stockpiled or not, before being abandoned, but does not include sludge, screenings or matter removed or generated from desludging, desilting or dredging works
6.2.3 Under the WDO, wastes can only be disposed of at designated waste disposal facilities licensed by Environmental Protection Department (EPD). Breach of this Ordinance can lead to a fine and/or imprisonment. The WDO also stipulates the requirements for issuing licenses for the collection and transportation of wastes.
Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C)
6.2.4 According to the definition under the Waste Disposal (Chemical Waste) (General) Regulation, chemical waste includes scrap materials or unwanted substances specified under Schedule 1 of the Regulation, if such a substance or chemical occurs in such a form, quantity or concentration that causes pollution or constitutes a danger to health or risk of pollution to the environment. It provides regulations for chemical waste control, and administers the possession, storage, collection, transportation and disposal of chemical waste. EPD has also issued a ‘guideline’ document – the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes (1992), which details how the Contractor should comply with the regulations on chemical waste.

6.2.5 Under the Waste Disposal (Charges for Disposal of Construction Waste) Regulation, enacted in January 2006, construction waste delivered to a landfill for disposal must not contain more than 50% by weight of inert material. Construction waste delivered to a sorting facility for disposal must contain more than 50% by weight of inert material, and construction waste delivered to a public fill reception facility (PFRF) for disposal must consist entirely of inert material.
Land (Miscellaneous Provisions) Ordinance (Cap. 28)
6.2.6 The inert portion of construction and demolition (C&D) materials may be taken to public filling facilities including public filling area, public filling barging points and stockpiling areas. These facilities usually form part of land reclamation scheme and are operated by Civil Engineering and Development Department (CEDD). The Land (Miscellaneous Provisions) Ordinance requires that individuals or companies who deliver public fill to the public filling facilities to obtain Dumping Licences. The licences are issued by CEDD under delegated authority from the Director of Lands.
Public Health and Municipal Service Ordinance (Cap. 132)
6.2.7 The Public Cleansing and Prevention of Nuisances Regulation under the Ordinance provides control on illegal tipping of wastes on unauthorised (unlicensed) sites.
Construction & Demolition (C&D) Material Management Plan
6.2.8 According to the “Project Administrative Handbook Chapter 4, Section 4.1.3”, published by CEDD, for Designated Projects and if the project generates more than 50,000m3 of C&D materials, a Construction and Demolition Materials Management Plan (C&DMMP) has to be prepared and signed off by a D1 (Directorate pay scale point 1) officer and submitted to the Public Fill Committee (PFC) for approval.
6.2.9 ETWB TCW No. 19/2005, Environmental Management on Construction Site, includes the procedures and requirements on waste management and sets out the policy for the Contractor to prepare and implement an Environmental Management Plan (EMP), which includes the Waste Management Plan (WMP), for onsite sorting and waste reduction of C&D materials.
Trip Ticket System for Disposal of Construction & Demolition Materials
6.2.10 The trip-ticket system is a recording system for orderly disposal of construction waste to disposal sites (i.e., PFRFs) by trucks. The Contractor is required to complete a standard trip-ticket form outlining the details of the transportation vehicle, contents of the vehicle (type and approximate volume of waste) and the designated disposal facility. Once the waste is delivered to the designated facility, a receipt is issued to the vehicle operator for return to the project engineer or architect representative for verification of the contractor's compliance with the policy requirements.
6.2.11 The implementation of such a system has ensured a certain level of accountability between the project proponent, engineer/architect and the contractor. Moreover, it facilitates the recording of waste as it arrives at the landfill or public filling area and minimise the potential for cross-contamination with other waste which the vehicle operator may otherwise likely pick-up and route to the disposal facility. This system assumes that the contractor will bear the responsibility for the sorting (where applicable) of the construction waste generated on their site prior to its disposal.
6.3 Description of the Environment 6.3.1 Based on the review of aerial photographs (Appendix 7.1), the Project was once situated partially
on fish ponds and surrounding areas were mainly natural terrain, covered in vegetation and floodplains. Filling of the ponds and nearby floodplains took place in the early 1980s until 1988.
6.3.2 According to current Project design, an underground public vehicle park will be developed and excavation is anticipated. Based on previously conducted GI investigations, no sediments have been identified within the Project Site boundary but pond deposits have been identified approximately 50 m from Site boundary (Appendix 7.2).
6.3.3 No sediment is anticipated from the excavation of underground carpark but if any sediment is encountered in the future during excavation, a Sediment Assessment Study will have to be conducted to ascertain the volume and type of sediment, and identify the disposal method. The total volume of excavation at the Project Site is estimated to be 78,000 m3.

6.3.4 Other various wastes are also anticipated to be generated during the construction phase which can be divided into different key categories based on their composition and ultimate method of disposal. The type of wastes generated from Project-related activities include:
• Construction and demolition (C&D) materials;
• Chemical waste; and
• General refuse.
6.3.5 Each type of the above waste arising is described in Section 6.5, together with an evaluation of the potential environmental impacts associated with the waste generation, handling, storage, transport and disposal.
6.4 Assessment Approach and Methodology 6.4.1 The waste management hierarchy is to minimize waste generation. If waste generation cannot be
avoided, a material / waste management plan will be established prior to commencement of excavation and construction work to outline the methods that can be incorporated into the Project for waste minimisation, including reuse, recycling, matching disposal with other projects, handling, storage, transportation and disposal of expected waste materials.
6.4.2 The waste management hierarchy is a concept that shows the desirability of various waste management methods and comprises the following in order of preference:
- Avoidance;
- Minimization;
- Reuse / recycling;
- Treatment; and
- Disposal
6.4.3 The methods for assessing potential impacts associated with waste generated from the construction and operation activities of this Project include:
a) Identification of the construction activities which could give rise to waste generation;
b) Assessment of potential impacts from the management of different waste stream with respect to potential hazards, air and odour emission, noise, wastewater discharge and the public; and
c) Identification of activities which could generate wastes during operational phase and proposed control measures.
6.4.4 Prior to considering the disposal options for various types of waste, opportunities for reducing waste generation, onsite or offsite reuse and recycling have been evaluated. Measures which can be taken in the planning and design phases (i.e., by modifying the design approach) and in the construction phase for maximising waste reduction have been separately considered.
6.4.5 After considering all options and methods to reduce waste generation and maximising reuse opportunities, the types and quantities of waste required to be disposed are estimated and the disposal options for each waste stream are provided.
6.4.6 The disposal options recommended for the generated waste in this report have considered the result of the assessment. The impacts caused by handling (including stockpiling, labelling, packaging and storage), collection, and reuse / disposal of wastes are addressed, and the appropriate mitigation measures are discussed in the next section.
6.5 Identification of Potential Impacts Construction Phase
6.5.1 Construction is expected to commence in Q3 2023 and completed by Q2 2026.

6.5.2 The assessment on waste management implications are based on best available preliminary design information and it is anticipated majority of wastes are generated from site clearance and general excavation. Table 6.1 outlined the identified waste streams during construction phase.
Table 6.1 Waste Types and Sources During the Construction Phase
Waste Types Waste Sources Examples
Construction and Demolition (C&D) materials
(inert and non-inert)
• Site clearance
• General excavation
• Reinstatement and backfilling (if any)
Inert C&D materials:
• Rocks
• Soft materials
Non-inert C&D materials:
• Bamboo, timber, paper, plastic etc.
Chemical Waste
• Mechanical equipment maintenance
• The operation and maintenance of the plant and mechanical equipment
• Cleaning fluids, solvents, waste lubricating oil and fuel etc.
General Refuse • Construction works and onsite staff and workers • Food waste, cans, waste papers etc.
Construction and Demolition (C&D) materials
6.5.3 C&D materials contain a mixture of inert and non-inert materials and is mainly generated from the site clearance activities, construction of buildings and superstructures. The quantity of C&D material to be produced from the construction is estimated to be approximately 79,450m3.
6.5.4 Inert C&D materials generated from construction activities would include, but not limited to rock, soil, concrete, asphalt, bitumen and soft granular materials that can be transported to public fill. Inert C&D materials will be used onsite as backfilling as much as possible before transporting to public fill.
6.5.5 Non-inert C&D materials generated from construction activities would include, but not limited to bamboo, timber, vegetation, paper and plastic that cannot be transported to public fill. Non-inert C&D materials will be sorted onsite and taken to the appropriate recycling facilities. Excess non-recyclable non-inert C&D materials will be disposed of at landfill. No imported fill is required.
6.5.6 The quantities of materials generated during site clearance and the recommended disposal outlets are shown in Table 6.2. The proposed outlet of the C&D materials is subject to agreement with EPD and CEDD at later stages of the Project. It is conservatively assumed that the excavated materials will only be reused within the corresponding site where the materials are generated. As the Project generates more than 50,000 m3 of C&D materials, a Construction and Demolition Material Management Plan (C&DMMP) is required and will be derived in the later stages of the Project.
6.5.7 The inert materials should be segregated from the C&D materials onsite for reuse as far as practicable. In order to minimise the impact resulting from collection and transportation of C&D material for offsite disposal, the C&D material that could be reused onsite as fill materials as far as practicable. The surplus inert C&D materials could be disposed of at the Government's Public Fill Reception Facilities (PFRFs) for beneficial use by any other projects in Hong Kong. Liaison with the CEDD Public Fill Committee (PFC) on the management of C&D materials will be required before the commencement of construction work. No construction work is allowed to proceed until all issues on management of C&D materials have been resolved and all relevant arrangements have been endorsed by the relevant authorities including PFC and EPD.

Notes: [1] “Inert C&D Materials” includes all grade rock, top soil and excavated soil, broken concrete, asphalt, bitumen and granula r materials, etc [2] “Non-inert C&D materials” includes, but not limited to, bamboo, timber, paper and plastic, etc. [3] Approximately ratio for (inert waste) : (non-inert waste) is 9:1 “Monitoring of Solid Waste in Hong Kong, 2017” by EPD.
6.5.8 With the proper implementation of good construction site practice, waste reduction measures and mitigation measures recommendations outlined in Section 6.6, the onsite handling, reuse, transportation and disposal of C&D materials would not cause adverse environmental impacts.
Chemical Waste
6.5.9 Chemical wastes arising during the construction phase may pose environmental, health and safety hazards if not stored and disposed of in an appropriate manner as stipulated in the Waste Disposal (Chemical Waste) (General) Regulations. The potential hazards include:
• Toxic effects to workers;
• Adverse impacts on water quality from spills; and
• Fire hazards.
6.5.10 The maintenance and servicing of construction plant and equipment may generate some chemical wastes such as used solvents, contaminated rags and waste lubricating oil. It is difficult to quantify the amount of chemical waste that will arise from the construction activities since it will be dependent on the Contractor’s onsite maintenance requirements and the amount of plant utilised. However, it is anticipated that the quantity of chemical waste, such as waste lubricating oil and solvents produced from plant maintenance, will be small and estimate to be few litres per month. The amount of chemical waste to be generated will be quantified in the Waste Management Plan (WMP) to be prepared by the Contractor for the site.
6.5.11 Materials classified as chemical wastes will require special handling and storage arrangements before removal for offsite disposal at the approved Chemical Waste Treatment Facility (CWTF) or recycling by licensed facilities. Mitigation and control requirements for chemical wastes are detailed in Section 6.6. Provided that the handling, storage and disposal of chemical wastes are in accordance with these requirements, adverse environmental impacts are not expected.

General Refuse
6.5.12 The number of work force to be employed for Project construction is estimated to be about 100 workers. A domestic waste generation rate of about 0.87 kg/person/day2 would be assumed. It is estimated that the daily amount of general refuse that would be generated would be at most 87 kg/day.
6.5.13 Such refuse will be properly managed so that intentional or accidental release to the surrounding environment will be avoided. Disposal of refuse at sites other than approved waste transfer or disposal facilities will be prohibited. Effective collection of site wastes will be required to prevent waste materials being blown around by wind, flushed or leached into the marine environment, or creating an odour nuisance or pest/ vermin problem. Waste storage areas will be well maintained and cleaned regularly.
6.5.14 It is recommended that general refuse should be collected on a daily basis for disposal. With the implementation of good waste management practices at the site, adverse environmental impacts are not expected to arise from the storage, handling and transportation of workforce wastes.
Operational Phase General Refuse
6.5.15 Most of the wastes generated during operational phase would be general refuse consisting mixed waste, food waste and scraps, waste paper and recyclables from the five (5) carpark staff. Such waste will be properly managed by suitable waste collectors so that intentional or accidental release to the surrounding environment will not occur.
6.5.16 Again, with an assumption of 0.87 kg/person/day of domestic waste generation rate, the total general refuse generated from the operational phase is expected to be 4.35 kg/person/day. No significant waste implication is expected from the carpark staff. The quantity of general refuse is expected to be low with implementation of appropriate control measures, no adverse waste implications are anticipated during operational phase.
6.5.17 Effective collection of general wastes will be implemented to prevent waste materials from creating odour nuisance or pest/ vermin problem. Waste storage areas will be well maintained and cleaned regularly. To reduce waste and improve recycling, it is expected that waste such as waste paper, plastics and aluminium can be segregated for offsite recycling.
Chemical Waste
6.5.18 Chemical waste will be generated from various routine maintenance and servicing activities for electrical and mechanical equipment. Chemical waste such as waste lubricating oil, contaminated rags, waste paint, used solvents and spent chemicals are expected to be generated from these activities. It is difficult to quantify the amount of chemical waste that will arise from those activities at this stage since it will be dependent on the equipment maintenance requirements and the amount of equipment utilised. Mitigation and control requirements for chemical wastes are detailed in Section 6.6.
6.5.19 Chemical wastes may pose environmental, health and safety hazards if not stored and disposed of in an appropriate manner as stipulated in the Waste Disposal (Chemical Waste) (General) Regulation. Chemical wastes will require special handling and storage arrangements in accordance with the relevant regulations before removal for offsite disposal at the approved CWTF or recycling by licensed facilities. Provided that the handling, storage collection, transport and disposal of chemical wastes will be in accordance with these requirements, adverse environmental impacts are not anticipated.

6.6 Recommendation of Mitigation Measures Construction Phase Good Site Practices
6.6.1 Adverse impacts related to waste management such as dust, odour, noise and wastewater discharge will not be expected to arise, provided that good site practices will be 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 handling procedures;
• Provision of sufficient waste disposal points and regular collection of waste;
• Appropriate measures to minimise windblown litter and dust / odour during transportation of waste by either covering trucks or by transporting wastes in enclosed containers;
• Provision of wheel washing facilities before the trucks leaving the works area so as to minimise dust introduction to public roads; and
• Well planned delivery programme for offsite disposal such that adverse environmental impact from transporting the inert or non-inert C&D materials is not anticipated.
Waste Reduction Measures
6.6.2 Good management and control can prevent the generation of a significant amount of waste. Waste reduction is best achieved at the planning and design stage, as well as by ensuring the implementation of good site practices. Recommendations to achieve waste reduction include:
• Sort inert C&D materials to recover any recyclable portions such as metals;
• Segregation and storage of different types of waste in different containers or skips to enhance reuse or recycling of materials and their proper disposal;
• Encourage collection of recyclable waste such as waste paper and aluminum cans by providing separate labelled bins to enable such waste to be segregated from other general refuse generated by the work force;
• Proper site practices to minimise the potential for damage or contamination of inert C&D materials; and
• Plan the use of construction materials carefully to minimise amount of waste generated and avoid unnecessary generation of waste.
6.6.3 In addition to the above measures, specific mitigation measures are recommended below for the identified waste arising to minimise environmental impacts during handling, transportation and disposal of these wastes.
C&D Material
6.6.4 In order to minimise impacts resulting from collection and transportation of inert C&D materials for offsite disposal, the excavated materials should be reused onsite as fill material as far as practicable. In addition, inert C&D materials generated from excavation works could be reused as fill materials in local projects that require public fill for reclamation.
6.6.5 The surplus inert C&D materials will be disposed of at the Government’s PFRFs for beneficial use by other projects in Hong Kong.
6.6.6 Liaison with the CEDD PFC on the allocation of space for disposal of the inert C&D materials at PFRF is underway. No construction work is allowed to proceed until all issues on management of inert C&D materials have been resolved and all relevant arrangements have been endorsed by the relevant authorities including PFC and EPD.

6.6.7 The C&D materials generated from general site clearance should be sorted on site to segregate any inert materials for reuse or disposal of at PFRFs whereas the non-inert materials will be disposed of at the designated landfill site.
6.6.8 In order to monitor the disposal of inert and non-inert C&D materials at respectively PFRFs and the designated landfill site, and to control fly-tipping, it is recommended that the Contractor should follow the Technical Circular (Works) No. 6/2010 for Trip Ticket System for Disposal of Construction & Demolition Materials issued by Development Bureau. In addition, it is also recommended that the Contractor should prepare and implement a WMP detailing their various waste arising and waste management practices in accordance with the relevant requirements of the Technical Circular (Works) No. 19/2005 Environmental Management on Construction Site.
6.6.9 According to the Project Administration Handbook for Civil Engineering Works (2020 Edition) - Chapter 4, Section 4.1.3, the project office is required to draw up a C&DMMP at the feasibility study or preliminary design stage to PFC for approval for each project, which generates more than 50,000m3 of C&D material including rock or that requiring imported fill in excess of 50,000m3. Further measures have been introduced under Paragraph 4.1.3 of Chapter 4 of the PAH for Civil Engineering Works to enhance the management of C&D materials, and to minimize its generation at source. The enhancement measures include:
• Drawing up a Construction and Demolition Materials Management Plan (C&DMMP) at an early design stage to minimize C&D materials generation and to encourage proper management of such materials;
• Vetting of the C&DMMP prior to upgrading of the project to Category A in the Public Works Programme; and
• Providing the contractor with information from the C&DMMP in order to facilitate the preparation of Waste Management Plan (WMP) and to minimize C&D materials generation during construction.
Chemical Waste
6.6.10 For those activities which generated chemical waste, it may be possible to find alternatives to eliminate the use of chemicals, reduce the generation quantities or replace with a chemical type that is less harmful on the environment and less invasive on the health and safety of workers.
6.6.11 When chemical waste is produced at the construction site, the Contractor should register with the EPD as a Chemical Waste Producer, and to follow the guidelines stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Good quality containers compatible with chemical wastes should be used.
6.6.12 Appropriate labels should be securely attached on each chemical waste container, indicating the corresponding chemical characteristics of the chemical waste, such as explosive, flammable, oxidising, irritant, toxic, harmful, and corrosive, etc. The Contractor shall engage a licensed collector to transport and dispose the chemical wastes at the Chemical Waste Treatment Centre in Tsing Yi, or other licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.
6.6.13 In order to prevent leakage or spillage, chemical wastes shall be properly packed and held in labelled containers and stored in designated storage area. Container of chemical waste shall be closed or sealed. Whereas chemical waste that cannot be recycled should be disposed of at either the CWTC, or other licensed facility, as mentioned above.
General Refuse
6.6.14 General refuse should be stored in enclosed bins or compaction units separated from inert C&D materials. A reputable waste collector should be employed by the Contractor to remove general refuse from the site, separately from inert C&D materials. Preferably an enclosed and covered area should be provided to reduce the occurrence of 'wind-blown' light material.
Operation Phase General Refuse
6.6.15 General refuse should be collected on daily basis and delivered to the refuse collection point accordingly. A reputable waste collector should be employed to remove general refuse regularly to

avoid odour nuisance or pest/vermin problem. Sufficient recycling containers are recommended to be provided at suitable locations of the Project to encourage recycling of such waste as aluminium cans, plastics and waste paper.
Chemical Waste
6.6.16 If chemical wastes are expected to produce during operational phase, the Project Proponent should register with the EPD as a chemical waste producer and follow the guidelines stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Alternatives to eliminate the use of chemicals, reduce the generation quantities or replace with a chemical type that is less harmful on the environment and less invasive on the health and safety of workers can also be explored.
6.6.17 Good quality containers compatible with the chemical wastes should be used, and incompatible chemicals should be stored separately. Appropriate labels should be securely attached on each chemical waste container indicating the corresponding chemical characteristics of the chemical waste, such as explosive, flammable, oxidising, irritant, toxic, harmful, corrosive, etc. Licensed collector should be deployed to transport and dispose of the chemical wastes at the approved CWTC or other licensed recycling facilities, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.
6.6.18 In order to prevent leakage or spillage, chemical wastes shall be properly packed and held in labelled containers and stored in designated storage area. Container of chemical waste shall be closed or sealed. Whereas chemical waste that cannot be recycled should be disposed of at either the CWTC, or other licensed facility, as mentioned above.
6.7 Evaluation of Waste Management Implications 6.7.1 The types of wastes generated during the construction and operational phases have been assessed,
recommendations have been provided to minimise waste arising, and offsite disposal of each type of waste have been suggested.
6.7.2 C&D materials will inevitably be produced during excavation activities. Wastes generated from construction activities include inert and non-inert C&D materials, chemical waste and general refuse. Mitigation measures have been proposed following the avoidance-minimisation-recycling-reuse-treatment-disposal hierarchy.
6.7.3 Wastes generated during construction phase can be minimised through careful planning during the detailed design and with good site practice during construction. The potential for reuse of inert C&D materials within the Project will be rigorously explored throughout the course of the Project in an effort to minimise offsite disposal. C&D materials is suggested to be recycled onsite as much as possible. Various waste management measures and good site practices have been provided to minimise potential adverse impacts and to reduce the volume of waste.
6.7.4 During operational phase, no significant waste implication is expected from the carpark staff. The quantity of general refuse and chemical waste arising from the operational phase is minimal and can be minimised by implementing an effectual waste handling system and waste reduction programme, and by hiring a reputable waste collector. Chemical waste register with the EPD as a chemical waste producer and follow the guidelines stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. As such it is considered to have no adverse environmental impacts.
6.7.5 Provided that the wastes are managed by implementing all the recommended mitigation measures, no significant environmental impact is anticipated from the waste management implications.

7 LAND CONTAMINATION REVIEW 7.1 Introduction 7.1.1 This section examines any potential contaminated land issues which may arise during the
construction phase and to propose remediation measures if necessary.
7.1.2 Contaminated land refers to land which has been polluted by hazardous substances as a result of industrial or commercial operations carried out on and around the site over a number of years. Very often, these contaminants pose hazardous risks or cause detrimental effects to the land users or the nearby environment.
7.2 Environmental Legislation, Standards and Guidelines 7.2.1 The relevant legislation, standards and guidelines applicable to the present study of contaminated
land issues for the Project Site and infrastructure works boundary include:
• Practice Guide for Investigation and Remediation of Contaminated Land, August 2011 (Practice Guide);
• Guidance Note for Contaminated Land Assessment and Remediation, August 2007 (Guidance Note); and
• Guidance Manual for Use of Risk-Based Remediation Goals for Contaminated Land Management, December 2007 (Guidance Manual).
• Annex 19 of the TM-EIAO, Guidelines for Assessment of Impact On Sites of Cultural Heritage and Other Impacts (Section 3: Potential Contaminated Land Issues), EPD, 1997
7.2.2 Under Annex 19 of the TM-EIAO, a number of potentially contaminating historical land uses should be considered, including oil installations, gas works, metal workshops, car repair and dismantling workshops, which have the potential to cause or have caused land contamination.
7.2.3 The methodology for conducting the study of contaminated land issues will be carried out in accordance with the Practice Guide and Guidance Manual. In addition to the above, references will also be made from the Guidance Note.
7.2.4 Desktop review, site reconnaissance and a review of historical and current land uses will provide information and guidance to characterise and identify if potential contamination exists or may be present during the construction and operation of the Project. Under the Guidance Note, a land contamination assessment shall include at minimum the following:
a) Provide a clear and detailed account of present land use and relevant past land use activities that may lead to potential land contamination;
b) Identify areas of potential contamination and associated impacts, risks or hazards to human health and the environment; and
c) Conclude and provide recommendation if further works regarding land contamination issues are required for the Project.
7.3 Description of the Environment 7.3.1 The Project is located in Tung Tau Industrial Area, a developed rural area in Yuen Long and the site
is surrounded by industrial buildings and residential establishment. The area is relatively flat, encompassed by access roads and cycling tracks. Figure 2.1 illustrated the location of the Project Site.
7.3.2 The area of the Project Site is approximately 1.4 hectares. Current land use at the Project Site is a playground consisting of open space, basketball courts, soccer fields and public washroom.

7.3.3 The assessment area refers to the boundary of the Project Site, which is bounded by Hong Yip Street, Po Yip Street, Keung Yip Street and Wang Yip Street East.
7.4 Assessment Approach and Methodology 7.4.1 According to the Practice Guide, site appraisal shall precede to determine the need for site
investigation, and to provide the information to support a contamination assessment, which the findings will subsequently determine if site remediation is required.
7.4.2 Under EPD’s Practice Guide, if a site is found to be contaminated, no construction activities or development of the site should be carried out until the remediation works have been validated and approved by EPD. This assessment may take up to 12 months or longer depending on the extent of contamination. It is therefore important that the Project Proponent undertake the initial evaluation by considering, as early as possible in the planning process, whether contamination is an issue and pose a risk to the Project development.
7.4.3 As land contamination is often linked to past uses of land and is more likely to have occurred when land is or was used or zoned for industrial, agricultural or commercial purposes, the review of historical land use and site appraisal include consideration of information such as, but not limited to:
a) Desktop review of existing and historical survey maps;
b) Interpretation of existing and historical aerial photographs;
c) Review of previously conducted Ground Investigations (GI) and boreholes;
d) Review of land use record, permitted uses of existing private lots; and
e) Site inspection and its vicinity to verify the gathered information.
7.4.4 The site inspection was carried out to identify any physical clues of contamination, such as the presence of industrial-related activities or building structures, underground storage tanks (USTs), chemical drums or oil stains, unnatural colours / odours and abandoned piping / mechanical components at the site.
7.5 Desktop Appraisal and Site Geology 7.5.1 Detailed desktop reviews have been conducted to review past and present land uses, activities and
installations in the vicinity of the Project Site boundary that may pose potential for contamination to the land.
7.5.2 Existing information from historical land contamination site investigations and other contamination reports for areas located within the vicinity of the Project Site have been reviewed, including the following:
7.5.3 The Geological Map of Hong Kong Web-based Edition – 2006, published by the Geotechnical Engineering Office, and aerial photos indicate that the Project Site is situated on the Lok Ma Chau Formation. The stratigraphy consisted of carboniferous metamorphosed sedimentary rocks and sandstones with ages ranging from approximately 354 to 280 million years before present.
7.5.4 The development history of the Project Site and surrounding areas were reviewed with the aid of aerial photographs and historical land uses to identify known or potential environmental concerns. Historical aerial photographs are included in Appendix 7.1.
7.5.5 According to the first aerial photograph, the Project Site was observed serving as fish ponds and surrounding areas were mainly natural terrain, covered in vegetation. Site clearance and development took place progressively from early 1980s to until 1988, medium to high-rise industrial buildings surrounding the site were observed. According to historical sources, the Tung Tau Industrial Area Playground was commissioned in 1989.
7.5.6 Pond sediments were identified in previously conducted GI investigations (Appendix 7.2), no sediments have been identified within the Project Site boundary but pond deposits have been identified approximately 50 m from Site boundary. The GI was conducted previously by:

contamination were observed at the Site. Potential contamination of historical and current land uses to the Project Site is not anticipated.
7.7 Government Records 7.7.1 Various HKSAR Government Departments listed below have been approached on the historical land
use, chemical storage, and accident records for further identification of potential land contamination. Replies from government departments are included in Appendix 7.4.
Environmental Protection Department (EPD)
7.7.2 Request letter was sent to EPD on 6 October 2021 to identify historical records of chemical and dangerous spillage / leakage. A reply from EPD dated 28 October 2021 indicated no accidents of such has been reported in the past three years.
7.7.3 In order to identify and current and previous chemical waste producers (CWPs) on the Project Site, an appointment with the EPD was made on 5 November 2021 to obtain a list of CWPs. A full list of valid and invalid CWPs nearby the Project Site is presented in Appendix 7.5. Review of CWPs revealed the nature of businesses adjacent to the Site (also verified by visual site inspection) include car repair and motor vehicle maintenances, tyre servicing and fuel injection pump services. However, there is no CWP in connection to the Site. No industrial activities, oil installations, gas works, metal workshops, car repair and dismantling workshops, which have potential to cause land contamination existed at the Project Site.
Fire Services Departments (FSD)
7.7.4 To identify the registration records of Dangerous Goods (DG) and the historical records of dangerous goods spillage / leakage, a letter was sent to FSD on 6 October 2021. However, only an interim reply (acknowledge letter) was received at the time of report issuance.
Lands Department (LandsD)
7.7.5 A request letter was sent to LandsD on 6 October 2021 to identify the current and past land uses of the Project Site and reported land contamination issues. Reply from LandsD has not been received at the time of report issuance.
7.7.6 Based on the above information provided by various Government Departments, the potential contamination to the land is low as there are no record of chemical spillage and/or leakage, and an absence of Underground Storage Tank (UST).
7.8 Future Land Use 7.8.1 Future land use plan at present is that the Project Site will be developed into a public open
recreational playground and an underground public vehicle park. This type of land use is regarded as open space and there will be no land use change.
7.9 Evaluation of Land Contamination Issues 7.9.1 The potential contaminated area at the Project Site is determined according to historical and current
land uses and activities potentially leading to soil or groundwater contamination.
7.9.2 Based on the review of aerial photographs, visual site inspection and government records, no suspected land contamination due to historical or current land uses is identified in the Project Site and its vicinity. No hotspots or stains are identified during site inspection.
7.9.3 In view of site history, potential land contamination for the Project Site is not anticipated. No land contamination impacts are expected during the construction phase of the Project. Further contaminated soil sampling and testing is therefore deemed not required.

8 CONCLUSION 8.1 Overall 8.1.1 A Preliminary Environmental Review (PER) has been conducted for the Re-development of Sports
Facilities with Public Vehicle Park in Tung Tau Industrial Area to ascertain the environmental acceptability of the Project.
8.1.2 The proposed development is a re-development of Tung Tau Industrial Area Playground with incorporation an underground public vehicle park and reprovision of existing facilities, including one 7-a-side hard-surfaced soccer pitch cum handball court, one multi-purpose hard-surfaced court (one 7-a-side hard-surfaced soccer pitch or two 5-a-side soccer pitches or two handball courts), two basketball courts, retractable spectator stand, a service block and other ancillary facilities. Potential impacts associated with air quality, noise, water quality, waste management have been reviewed in this assessment.
8.2 Air Quality 8.2.1 Dust generated from construction activities is the primary concern during the construction phase.
Due to the small-scale of the Project, dust emission induced by the Project would be expected to be insignificant. With the implementation of proper mitigation measures, no adverse air quality impacts are anticipated during construction phase.
8.2.2 For operation phase, no adverse air quality impacts are anticipated with no air-sensitive uses located within the buffer distance of 5m from the road kerb of the surrounding roads.
8.3 Noise 8.3.1 The construction activities will be within the small site area which is approximately 1.4 hectare in
size. The number of PME is expected to be limited. Given that the small scale and limited extent of construction, the construction noise is anticipated to be minimal. Construction noise impacts could be effectively mitigated by inclusion of proper contracts clauses for construction noise mitigation in the works contracts. With implementation of recommended noise mitigation measures, the construction noise impact to the NSRs in the vicinity is anticipated to be insignificant.
8.3.2 The induced traffic would be limited to private vehicles by users of PVP. Given the limited parking spaces and minimal induced traffic, significant traffic noise impact from the Project is not anticipated.
8.3.3 With the adoption of the maximum permissible SWLs for the proposed fixed plants, the impact noise levels at all representative NSRs would comply with the relevant fixed noise criteria. Therefore, adverse fixed noise sources impact to all representative NSRs is not anticipated. The maximum SWL should be implemented and refined during the detailed design stage of the Project by the Contractor/ future operator taking into account the exact design details of plants and the actual surrounding conditions. Any planned noise sensitive uses identified at later stage should also be incorporated and taken into consideration for the assessment.
8.4 Water Quality 8.4.1 During the construction phase, potential water quality impact would be generated from site run-off
and sewage from workforce from various construction activities. With the implementation of the recommended mitigation measures, no adverse water quality impact from the construction works for the Project is anticipated.
8.4.2 During operation phase, the operation of the proposed development does not impose a significant additional load to the existing sewerage system and the capacity of existing sewer pipes is adequate

to tolerate the additional load from the Project. No operational water quality impact from the Project is anticipated.
8.5 Waste Management 8.5.1 During construction phase, wastes generated by the construction activities are likely to include C&D
materials, general refuse from the workforce and chemical waste from any maintenance of construction plant and equipment. Wastes generated during construction phase can be minimised through careful planning during the detailed design and with good site practice during construction. Provided that the identified wastes are handled, transported and disposed of using approved methods and that the recommended good site practices are strictly followed, adverse environmental impacts are not anticipated during construction of the Project.
8.5.2 During operational phase, the key waste types include general refuse generated within the site, as well as chemical waste from routine servicing and maintenance activities for the Electrical & Mechanical (E&M) equipment. Provided that all these wastes are handled, transported, and disposed of in strict accordance with the relevant legislative requirements and the recommended mitigation measures are properly implemented, no adverse environmental impact is expected during the operational phase.
8.6 Land Contamination 8.6.1 Based on the review of aerial photographs, visual site inspection and government records, the
findings revealed that no potential land contamination issue is anticipated from the past and present land use activities at the Project Site.
8.6.2 In view of site history, potential land contamination for the Project Site is not anticipated. No land contamination impacts are expected during the construction phase of the Project. Further contaminated soil sampling and testing is therefore deemed not required.
