Construction of Road P1 and a slip-road from KSWH to Road D3 partly located within the "Conservation Area” of Yuen Tau Shan

Note:

1 Subject to an Environmental Permit (EP) application under this EIA Study.

2 Subject to separate EIA Study, as required.

DP 1 - Construction of New Primary Distributor Road (Road P1)

1.3.3 The majority of the new primary distributor road (Road P1) located under the existing KSWH at the western Project area (approximately 3.2 km in length), provides a service access with 2 lanes per direction to both the “I” areas and the new core area around the proposed HSK Station. Alignment options have been reviewed to minimise impacts on the DBL project mitigation ponds (wetland compensation area) located in the immediate vicinity of the road, opposite Site 3-26.

1.3.4 The at-grade alignment will have several connections to the proposed district distributor roads (Road D1/D5/D6/D7/D8). Two pairs of slip roads will be constructed to connect between the at-grade Road P1 and existing KSWH. In addition, a pair of slip roads along Road P1 will be constructed between the existing KSWH and at-grade Road D6 to facilitate the traffic connection at north western part of the Project area.

DP2 - Construction of Eight New Distributor Roads (Roads D1 to D8)

1.3.5 A total of eight Distributor Roads are proposed. All will provide a major role in servicing proposed land uses and existing developments (including villages where linkages have been provided). These comprise:

· Road D1: This road provides a partly dual three and partly dual two, west to east primary connection at the northern part of the Project area linking Tin Shui Wai (TSW) with the KSWH and providing links to District Distributors that provide the secondary links to the south of the Project area. The local road from a section of Road D1 near Lau Fau Shan to serve the residential sites and commercial sites in the northern part of the Project area will be restricted to private cars access only. A section of Road D1 from KSWH to road junction of Road D4/D3/D1 will be partly depressed and partly decked-over to allow crossing of the EFTS alignment. A section of Road D1 near the roundabout with Tin Wah Road will be a bridge structure (not greater than 30 m in length between abutments) to allow the local road to/from residential sites in the northern part of the Project area in parallel with Lau Fau Shan Road to the end of Site 2-1.

· Road D2: Comprises a north-south primary route that links to Ping Ha Road and Hung Tin Road. Road D2 is planned to dual 2 standards by widening of existing Ping Ha Road to enhance the magnitude of residential development and reduce the environmental adverse noise impact that is realisable in the north east of the Project area. The link will accommodate the traffic capacity currently carried along the Tin Ying Road and Ping Ha Road and also has the capacity to service existing and proposed development. Most of the Road D2 is constructed at-grade, except a section of approximately 450 m which is a depressed road in order to improve pedestrian connectivity between the residential Sites 1-5, 1-6 and 2-31.

· Road D3: Provides a link between Road D4/D1 and Road D5. A depressed road will be constructed near the roundabout of Road D4/D1 to avoid reduction on the traffic flow efficiency to and from Road D1. A section of Road D3 will be constructed in abutment for connection from slip road from KSWH to the at-grade section of Road D3.

· Road D4: Provides a link between Road D1/D3 to Road D2 to facilitate an eastward connection to TSW New Town and Castle Peak Road via Road D4. This route will serve to alleviate the pressure on other west to east links. A section of Road D4 of approximately 300 m length will be constructed as depressed road with partial pedestrian decking-over to facilitate access, and thus increasing connectivity between Sites 2-30 and 2-32.

· Road D5: Provides a link between the services areas (e.g. Special Industry (Logistics Facility)) and connects to Road P1 in the west and Tin Ha Road in the east. The whole section of Road D5 will be at-grade with a roundabout with Road D3.

· Road D6: Connects with Road D8 along its alignment. The route will play a major role in servicing the proposed HSK Station and related development as well as the proposed commercial sites and mixed commercial/residential development. To avoid conflict to pedestrian activity in the Regional Plaza near the proposed HSK Station, half of Road R6 will be constructed in depressed road of approximate 550 m length with partial decking-over in the Regional Plaza section.

· Road D7: Road D7 provides access from Road P1 to the commercial sites at Sites 4-12, 4-13 and 4-16.

· Road D8: Road D8 provides a connection between the proposed Road P1 and Castle Peak Road. The route will provide an important west to east link whilst also providing a major means of access to the proposed HSK Station, the civic node at Site 4-31, and the commercial and residential developments located east of the proposed HSK Station. The road will be constructed at-grade with a depressed EFTS crossing under Road D8.

DP3 - Construction of New West Rail Hung Shui Kiu Station (Site 4-34)

1.3.6 A new WRL Station will be built at the south of the Project area. This railway station will be important for transportation in the southern part of Project area in addition to the road traffic at Road P1 and Castle Peak Road. Railway associated facilities such as ventilation shafts etc. would be located in the vicinity of the station. As the construction of the station would be undertaken under a separate EIA, station details are not currently available. However, a proposed schematic layout of the station is proposed for the purpose of this EIA (Figure 4.8.1). Any details required for the EIA assumptions are described in the relevant EIA sections (e.g. Chapter 4 – Noise Impact).

DP4 - Construction of Environmental Friendly Transport Services –Potential DP subject to further review

1.3.7 The proposed EFTS traverses the core residential, commercial and other land reserves within the Project area. The separation between stations is walking distance to facilitate public access. A modern low profile tram system has been assumed for the purpose of the EIA; however, the system that will ultimately be used is subject to further study. The GTC reserve allocated to the tram will be also abutted by cycle and pedestrian routes. This will allow the public to cycle within vehicle free routes. The quality of the reserve will be enhanced through the application of high and low profile landscape treatments. A depot associated with the proposed EFTS is located at Site 3-18. Most of the alignment of the EFTS will be constructed at-grade, except some sections will be depressed and elevated at junctions within the proposed carriageway.

DP5 - Construction of Slip Roads between: Road D8 Junction and Existing Castle Peak Road; Junction of D8/P1 and Junction of D7/P1; and KSWH Connection to Road D3

1.3.8 The proposed slip roads have a length of more than 100 m in length between abutments. Two pairs of slip roads will be constructed near the two roundabouts of Road D8 and Road D7. They provide connection between at-grade Road P1 and existing elevated KSWH in order to improve the traffic connectivity to the Project area. Another pair of slip roads will be constructed from the existing KSWH to at-grade Road D3 to provide direct traffic connection to the port-back up areas and the logistic facilities at the western part of the Project.

DP6 - Construction of Partly Depressed and Partly Decked-over Roads Located at Road D2, D4 and D6

1.3.9 Some sections of Road D2, D4 and D6 are enclosed by decking above and by structure on the side for more than 100 m and hence classified as DP under Item A.9 Part 1, Schedule 2 of the EIAO.

1.3.10 The district open space (Site 2-32) located to the south of Road D4 and west of Road D2 is intended to act as a buffer between new developments and the villages to the south, and provides flexibility for community farming and farming markets. This district open space and the proposed residential sites are however separated by Roads D2 and D4. A section of the Road D2 is therefore decked-over for approximately 450 m with intermittent openings to improve pedestrian access/connectivity between the residential sites near the TSW Main Channel to “LO”, via Site 2-31 and crossing Road D4. Similarly, to enhance connectivity with the district open space (Site 2-32), it is proposed to deck over approximately 250 m of Road D4 in order to provide pedestrian crossing and flow from north to south across Road D4.

1.3.11 Approximately 300 m with intermittent openings of Road D6 would be decked-over near the proposed Regional Plaza near the proposed HSK Station. The decked-over structure is intended to maximise the area of Regional Plaza and allow pedestrian crossing to the EFTS station and the western part of development. In particular, a 20 m wide pedestrian street lined with retail shops, cafés and restaurants is proposed as a major pedestrian connection between the communities to the south of Castle Peak Road and the Town Centre. The proposed arrangement of depressing and decking over a section of Road D6 will allow seamless at-grade crossing between commercial complexes on two sides of the proposed HSK Station and provide a pleasant walking environment within the Town Centre.

DP7 - Construction of a New Container Back-up and Storage Area – Potential DP subject to further review

1.3.12 The western part of the Project is planned to serve as “PBU” and logistic facilities area to accommodate existing brownfield operations within the Project area. It is intended to locate these facilities at the west of the Project area to minimise interface issues with planned residential development and communities. The details of this development (i.e. size/area of container back-up area, container storage area) would be determined at the detailed design stage. This development would be a potential designated project where the area was more than 5 ha and within 300 m of an existing or planned receiver (e.g. Sites 3-1, 3-4, 3-5, 3-13 and 3-14).

DP8 - Construction of New HSK Sewage Treatment Works

1.3.13 As the planned SW STW – Phase 1 is not designed to cater for the additional flow generated from the Project, a new HSK STW will be provided to handle the sewage arising from the new population and employment in the Project area. The new HSK STW will be implemented in two phases to serve the different phases of development.

1.3.14 The new HSK STW (Phase 1) will start operation before Stage 2 of the Project (i.e. 2031) to handle the sewage from the Project using Site 3-26. The potential for using part of the land of the existing the SW STW for further expansion of the HSK STW (Phase 2) will also be explored, subject to review of the future population growth. The 85,500 m³ per day.

1.3.15 As the construction of the STW would be undertaken under a separate EIA, there is currently no information regarding the layout. Any details required for the EIA assumptions are described in the relevant EIA sections (e.g. Chapter 6 – Sewage and Sewerage Treatment Implications).

DP9 - Construction of Four New Sewage Pumping Stations

1.3.16 The sewerage arrangement for the intermediate and ultimate development stages, include four SPS (SPS1, SPS2, SPS3 and SPS4), which will be required to convey the sewage to SW STW- phase 1 and the proposed new HSK STW. The four new SPS will be implemented in two stages and designed with a capacity of 27,000 m³ per day (SPS1), 39,500 m³ per day (SPS2), 11,000 m³ per day (SPS3), and 68,000 m³ per day (SPS4) (Sites 2-34, 3-41, 3-48 and 4-35, respectively).

1.3.17 Construction of SPS1 and SPS2 (general layout presented in Figures 2.14 and 2.15 of the EIA Report, respectively) will be carried out in the intermediate development stage in order to cope with the completion of advance works for the Project. SPS1 is designated to convey sewage from the southern Project area next to Castle Peak Road to SPS2 and then to San Wai STW. SPS2 sewage catchment also includes the western Project area next to KSWH. These two SPSs are tentatively scheduled to be completed by 2029.

1.3.18 Construction of SPS3 and SPS4 (general layout presented in Figures 2.16 and 2.17 of the EIA Report, respectively) will be carried out in the ultimate development stage. SPS3 will receive sewage flow from the middle part of the Project area and then convey it to SPS2 for further pumping to the future new HSK STW. SPS4 will collect sewage from northern part of the Project area and divert the sewage from Tin Wah Road to San Wai STW through a proposed new rising main. These two SPSs are tentatively scheduled to be completed by 2031.

1.3.19 Since all these SPSs are with an installed capacity of more than 2000 m³ per day and are located within 150 m from existing and/or planned residential area or educational institution, these SPSs are classified as DPs under Item F.3, Part 1, Schedule 2 of the EIAO.

DP10 - Construction of Flushing Water Service Reservoirs for Reuse of Reclaimed Water at Tan Kwai Tsuen and Fung Kong Tsuen

1.3.20 In order to achieve a sustainable development, reclaimed water from the sewage treatment plant will be reused for flushing water serving the Project. To facilitate the reuse of reclaimed water, service reservoirs at Tan Kwai Tsuen and Fung Kong Tsuen would be constructed (Site 3-3 and Site 5-40).

DP11 - Construction of a Refuse Transfer Station

1.3.21 In the northern part of the Project area along the KSWH, Site 3-12 has been proposed for the provision of a new “RTS” to support the existing NWNT “RTS” and cope with the new population waste generation. A Community Green Station is also co-located within the site to enhance environmental education and help collect different types of recyclables in the local community, which could provide synergistic effect to achieve better operational efficiency.

DP12 - Construction of Road P1 and a Slip Road from Kong Sham Western Highway to Road D3 Partly within the “Conservation Area” of Yuen Tau Shan

1.3.22 A north bound slip road from KSWH is proposed to provide direct access via Road D4 to west part of the Project area which will be located next to KSWH. The slip road and part of Road P1 will be partially located in the “CA” designation of Yuen Tau Shan. The alignment of Road P1 and the slip road will be constructed along the reinforced concrete flood storage ponds to avoid loss of natural/semi-natural habitats.

4 Air Quality Impact

4.1 Introduction

4.1.1 As identified in the EIA Report, the Project would not cause any adverse air quality impacts during operation phase. Separate EIA studies would be carried for proposed HSK Station, proposed EFTS, container storage area, RTS and the new HSK STW and the required operational EM&A requirements for these facilities would be recommended in the individual EIA Reports. This section presents the requirements, methodology, equipment, monitoring locations, criteria and protocols for the monitoring and audit of air quality impact during the construction phase of the Project and the requirements of the commissioning tests for deodorising units of the SPSs.

4.1.2 The objectives of the air quality monitoring shall be:

· to identify the extent of construction dust impact on sensitive receivers;

· to determine the effectiveness of mitigation measures to control fugitive dust emission from activities during the construction phase;

· to audit the compliance of the Contractor with regard to dust control, contract conditions and the relevant dust impact criteria;

· to recommend further mitigation measures if found to be necessary; and

· to comply with Action and Limit (A/L) Levels for air quality as defined in this Manual.

4.2 Air Quality Parameters

4.2.1 The major dusty construction activities of the Project would likely be site formation work, excavation work, loading/unloading activities, and demolition of existing buildings which would generate insignificant amount of small size particulates, hence, no significant Respirable Suspended Particulates (RSP) or Fine Suspended Particulates (FSP) impacts would be anticipated. Monitoring of 24-hour RSP and 24-hour FSP levels are not proposed. Therefore, only 1-hour Total Suspended Particulates (TSP) is recommended to be monitored and audited at the proposed monitoring locations.

4.2.2 The criterion against which ambient air quality monitoring to be assessed are:

· 1-hour TSP limit of 500 µg m^-3

4.2.3 This level should not be exceeded at Air Sensitive Receivers (ASRs).

4.2.4 Monitoring and audit of the TSP levels shall be carried out by the ET to ensure that any deteriorating air quality could be readily detected and timely action shall be undertaken to rectify such situation.

4.2.5 1-hour TSP levels should be measured to indicate the impacts of construction dust on air quality. The TSP levels should be measured by following the standard method as set out in High Volume Sampling Method for Total Suspended Particulates, Part 50 Chapter 1 Appendix B, Title 40 of the Code of Federal Regulations of the USEPA (hereinafter referred to as “HVS method”). Upon approval of EPD and IEC, an alternative sampling method of using direct reading methods which are capable of producing comparable results as that by the high volume sampling method can be used to indicate short event impacts.

4.2.6 All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, other local atmospheric factors affecting or affected by site conditions and work progress of the concerned site etc. shall be recorded in details. A sample data record sheet is shown in Appendix 4.1.

4.3 Monitoring Equipment

4.3.1 High volume sampler (HVS) in compliance with the following specifications shall be used for carrying out the 1-hour TSP monitoring:

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

· equipped with a timing / control device with ± 5 minutes accuracy for 24 hours operation;

· installed with elapsed-time meter with ± 2 minutes accuracy for 24 hours operation;

· capable of providing a minimum exposed area of 406 cm²;

· flow control accuracy: ± 2.5% deviation over 24-hour sampling period;

· equipped with a shelter to protect the filter and sampler;

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

· equipped with a flow recorder for continuous monitoring;

· provided with a peaked roof inlet;

· incorporated with a manometer;

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

· easy to change the filter; and

· capable of operating continuously for 24-hour period.

4.3.2 The ET shall be responsible for the provision of the monitoring equipment. He shall ensure that sufficient number of HVSs with appropriate calibration kit is available for carrying out the baseline, regular impacts monitoring and ad-hoc monitoring. The HVSs shall be equipped with an electronic mass flow controller and be calibrated against a traceable standard at regular intervals, in accordance with requirements stated in the manufacturers operating manual. All the equipment, calibration kit, filter papers, etc., shall be clearly labelled.

4.3.3 Initial calibration of the dust monitoring equipment shall be conducted upon installation and prior to commissioning at bi-monthly intervals. The transfer standard shall be traceable to the internationally recognised primary standard and be calibrated annually. The calibration data shall be properly documented for future reference by the concerned parties such as the IEC. All the data shall be converted into standard temperature and pressure condition.

4.3.4 The flow-rate of the sampler before and after the sampling exercise with the filter in position shall be verified to be constant and be recorded on the data sheet as shown in Appendix 4.1.

4.3.5 If the ET Leader proposes to use a direct reading dust meter to measure 1-hour TSP levels, he shall submit sufficient information to the IEC to prove that the instrument is capable of achieving a comparable result as that of the HVS before it may be used for the 1-hour sampling. The instrument shall also be calibrated regularly, and the 1-hour sampling shall be determined periodically by HVS to check the validity and accuracy of the results measured by direct reading method.

4.3.6 Wind data monitoring equipment shall also be provided and set up at conspicuous locations for logging wind speed and wind direction near to the dust monitoring locations. The equipment installation location shall be proposed by the ET and agreed with the ER and the IEC. For installation and operation of wind data monitoring equipment, the following points shall be observed:

· The wind sensors shall be installed on masts at an elevated level 10 m above ground so that they are clear of obstructions or turbulence caused by the buildings;

· The wind data shall be captured by a data logger. The data recorded in the data logger shall be downloaded periodically for analysis at least once a month;

· The wind data monitoring equipment shall be re-calibrated at least once every six months; and

· Wind direction should be divided into 16 sectors of 22.5 degrees each.

4.3.7 In exceptional situations, the ET may propose alternative methods to obtain representative wind data upon approval from the ER and agreement from the IEC.

4.4 Laboratory Measurement / Analysis

4.4.1 A clean laboratory with constant temperature and humidity control and equipped with necessary measuring and conditioning instruments to handle the dust samples collected, shall be available for sample analysis, and equipment calibration and maintenance. The laboratory shall be HOKLAS accredited or other internationally accredited laboratory.

4.4.2 If a site laboratory is set up or a non-HOKLAS accredited laboratory is hired for carrying out the laboratory analysis, the laboratory equipment shall be verified by the IEC and approved by the EPD. Measurement performed by the laboratory shall be demonstrated to the satisfaction of the IEC and EPD.

4.4.3 The IEC shall conduct regular audit of the measurement performed by the laboratory so as to ensure the accuracy of measurement results. The ET shall provide the ER with one copy of the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B for his/her reference.

4.4.4 Filter paper of size 8"x10" shall be labelled before sampling. It shall be a clean filter paper with no pinholes, and shall be conditioned in a humidity-controlled chamber for over 24-hour and be pre-weighed before use for the sampling.

4.4.5 After sampling, the filter paper loaded with dust shall be kept in a clean and tightly sealed plastic bag. The filter paper shall then be returned to the laboratory for reconditioning in the humidity-controlled chamber followed by accurate weighing by an electronic balance with a readout down to 0.1 mg. The balance shall be regularly calibrated against a traceable standard.

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

Note: (1) The monitoring period is subject to the construction programme of the relevant contracts in the Construction Stage.

4.5.2 The status and locations of the air quality sensitive receivers may change after issuing this Manual. In such case, the ET shall propose updated monitoring locations and seek approval from IEC and agreement from EPD on the proposal.

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

i. at the site boundary or such locations close to the major dust emission source;

ii. close to the air sensitive receivers as defined in the EIAO-TM;

iii. proper position/sitting and orientation of the monitoring equipment; and

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

i. a horizontal platform with appropriate support to secure the samplers against gusty wind shall be provided;

ii. two samplers shall be placed less than 2 m apart;

iii. 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;

iv. a minimum of 2 m of separation from walls, parapets and penthouses is required for rooftop samplers;

v. a minimum of 2 m of separation from any supporting structure, measured horizontally is required;

vi. no furnace or incinerator flue is nearby;

vii. airflow around the sampler is unrestricted;

viii. the sampler is more than 20 m from the dripline;

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

x. permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

xi. a secured supply of electricity is needed to operate the samplers.

4.6 Baseline Monitoring

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

4.6.2 Before commencing the baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.

4.6.3 TSP baseline monitoring should be carried out at all of the designated monitoring locations for at least 14 consecutive days prior to the commissioning of the construction works. 1-hour TSP sampling shall be done at least three times per day at each monitoring station when the highest dust impacts are expected. During the baseline monitoring, there should not be any construction or dust generating activities in the vicinity of the monitoring stations. General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources should also be recorded throughout the baseline monitoring period. A summary of baseline monitoring is presented in Table 4.2.

4.6.4 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 location shall be agreed with IEC and approved by EPD.

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

4.6.6 If the ET Leader considers that significant changes in the ambient conditions have arisen, a repeat of the baseline monitoring may be carried out to update the baseline levels. The revised baseline levels, in turn, the air quality criteria, shall be agreed with the IEC and EPD.

4.7 Impact Monitoring

4.7.1 The ET shall carry out impact monitoring during construction phase of the Project. 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. In case of non-compliance with the air criteria, more frequent monitoring, as specified in the Action Plan in the following section, should be conducted. This additional monitoring should be continued until the excessive dust emission or the deterioration in the air quality is rectified. The impact monitoring programme is summarised in Table 4.2.

4.7.2 The monthly schedule of the compliance and impact monitoring programme should be drawn up by the ET one month prior to the commencement of the scheduled construction period. Before commencing the impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit to ensure accuracy of the impact monitoring results.

Table 4.2 Summary of Construction Dust Monitoring Programme

Monitoring Period	Duration	Sampling Parameter	Frequency
Baseline Monitoring	Consecutive days of at least 2 weeks before commencement of major construction works	1-hour TSP	3 times per day
Impact Monitoring	Throughout the construction phase	1-hour TSP	3 times in every 6 days when documented and valid complaint was received

4.8 Event and Action Plan

4.8.1 The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring. The ET shall compare the impact monitoring results with air quality criteria set up for 1-hour TSP. Table 4.3 shows the air quality criteria, namely Action and Limit levels to be used. Should non-compliance of the air quality criteria occur, action in accordance with the Action Plan in Table 4.4 shall be carried out.

4.9 Performance Compliance Test

4.9.1 Performance compliance tests for the deodorising units of the four SPSs (DP9) are recommended to determine whether the odour removal efficiency meet the requirements as stated in the EIA Report. Odour sampling is proposed at the intake and exhaust locations for olfactometric analysis at the commissioning stage.

4.10 Mitigation Measures

Construction Phase

4.10.1 Mitigation measures for dust control have been recommended in the EIA Report. The Contractor shall be responsible for the design and implementation of these measures.

4.10.2 Recommended mitigation measures to minimise the adverse impacts on air quality during construction phases of the Project including all DPs are detailed in Section 4.10.3 below.

4.10.3 To ensure compliance with the guideline level and AQO at the ASRs, the Air Pollution Control (Construction Dust) Regulation should be implemented and good site practices should be incorporated in the contract clauses to minimise construction dust impact. A number of dust suppression measures are proposed to be implemented as follows:

· Watering once time per hour on active works areas and exposed areas so as to achieve a dust removal efficiency of 91.7%.

· When there are open excavation and spoil handling works, hoarding of 3 m high should be provided along the construction site boundary adjacent to the non-construction areas such as residential, educational institutes or recreation area in use so as to minimise the dust impact.

· Use of frequent watering for particularly dusty construction areas and areas close to ASRs.

· Side enclosure and covering of any aggregate or dusty material storage piles to reduce emissions. Where this is not practicable owing to frequent usage, watering shall be applied to aggregate fines.

· Open stockpiles shall be avoided or covered. Where possible, prevent placing dusty material storage piles near ASRs.

· Tarpaulin covering of all dusty vehicle loads transported to, from and between site locations.

· Establishment and use of vehicle wheel and body washing facilities at the exit points of the site.

· Provision of wind shield and dust extraction units or similar dust mitigation measures at the loading area, and use of water sprinklers at the loading area where dust generation is likely during the loading process of loose material, particularly in dry seasons/ periods.

· Provision of not less than 2.4 m high hoarding from ground level along site boundary where adjoins roads, streets or other accessible to the public except for a site entrance or exit. Good site practice shall also be adopted by the Contractor to ensure the conditions of the hoardings are properly maintained throughout the construction period.

· Imposition of speed controls for vehicles on site haul roads.

· Where possible, routing of vehicles and positioning of construction plant should be at the maximum possible distance from ASRs.

· Every stock of more than 20 bags of cement or dry pulverised fuel ash (PFA) should be covered entirely by impervious sheeting or placed in an area sheltered on the top and the 3 sides.

4.10.4 For the work site of the Work Contract nearest to the ASRs at Site 3-6, Site 3-8, Site 3-14, Site 4-20, and existing ASRs at Oaklands Court (A208), Ling Liang Church Primary School (A209, Tin Ha Road Playground (A310) and San Uk Tsuen (A702), it is recommended to reduce the active construction works area to one-third of monthly average work of the respective Work Contract so as to alleviate adverse dust impact.

Operation Phase

4.10.5 All facilities and areas with potential odour emission such as wet well, inlet chamber and screen chamber of the four SPSs are proposed to be covered and the exhausted air would be conveyed to a deodouriser (at least 90% of odour removal efficiency) for treatment before discharge to the environment. The ventilation system would also maintain a slight negative pressure within the facilities. The exhaust outlet of the deodouriser shall also be located away from the nearby air sensitive receivers as far as practicable. The screening wastes are proposed to be removed regularly (at least twice a week) from the four SPSs and would be properly packed and handled within the SPS structures and transported to designated landfill for disposal immediately after collection from the SPSs.

4.10.6 Regarding the odour impact due to the existing chicken farm, portion of Site 3-1 (“OU”, “PBU+SWU”), it is proposed that air sensitive uses at Site 3-1 should not be located at these exceedance zone or the fresh air intake of the building located at least 6 mAG

5 Noise Impact

5.1 Introduction

5.1.1 The EIA has predicted the potential construction noise impact, operation phase road traffic noise impact, railway noise impact and fixed plant noise impact from this Project.

5.1.2 Construction noise mitigation measures would be required to reduce noise levels to the stipulated standard. A noise monitoring and audit programme should be undertaken to confirm such mitigation measures would be implemented properly.

5.1.3 Mitigation measures of noise barriers would need to be implemented along the roadworks within the Project area. Road traffic noise levels should be monitored at representative NSRs, which are in the vicinity of the recommended direct mitigation measures, during the first year after road opening. The purpose of the monitoring is to ascertain that the recommended mitigation measures are effective in reducing the noise levels.

5.1.4 For fixed plant noise impact, the Contractor should carry out a noise commissioning test for planned fixed noise sources before operation of the relevant fixed plant noise sources, in order to ensure compliance of the operation airborne noise levels with the TM’s stipulated noise standard.

5.1.5 In this section, the requirements, methodology, equipment, monitoring locations, criteria and protocols for the monitoring and audit of construction noise impacts and operational traffic noise are presented.

5.2 Monitoring Parameters for Construction Noise

5.2.1 The construction noise levels should be measured in terms of the 30-minute A-weighted equivalent continuous sound pressure level (L_eq_(30-min)). L_eq₍_30-min) should be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays.

5.2.2 Supplementary information for data auditing and statistical results such as L₁₀ and L₉₀ should also be obtained for reference. Sample noise field data sheets are shown in Appendix 5.1 of this Manual for reference. The ET Leader may modify the data record sheet for this EM&A programme but the format of which should be agreed by the IEC.

5.3 Monitoring Equipment for Construction Noise

5.3.1 As referred to in the Technical Memorandum (TM) issued under the Noise Control Ordinance (NCO), sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements shall be accepted as valid only if the calibration level from before and after the noise measurement agree to within 1.0 dB.

5.3.2 Noise measurements shall not be made in fog, rain, wind with a steady speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in m/s.

5.3.3 The ET 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. The equipment installation location shall be proposed by the ET Leader and agreed with the IEC and EPD.

5.4 Monitoring Locations for Construction Noise

5.4.1 Figures 5.1 and 5.2 show the construction noise monitoring stations. The details of proposed noise monitoring stations are summarised in Table 5.1 below.

Note: (1) The monitoring period is subject to the construction programme of the relevant contracts in the Construction Stage.

5.4.2 The status and locations of noise sensitive receivers (NSRs) may change after issuing this Manual. If such cases exist, the ET shall propose updated monitoring locations and seek approval from the IEC and agreement from EPD of the proposal.

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

i. at locations close to the major site activities which are likely to have noise impacts;

ii. close to the NSRs; and

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

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

5.5 Baseline Monitoring for Construction Noise

5.5.1 Baseline noise monitoring shall be carried out daily in all of the identified monitoring stations for at least 2 weeks prior to the commissioning of the construction works. A schedule of the baseline monitoring shall be submitted to the IEC for approval before the monitoring starts.

5.5.2 During the baseline monitoring, there shall not be any construction activities in the vicinity of the monitoring stations.

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

5.6 Impact Monitoring for Construction Noise

5.6.1 Construction noise monitoring should be carried out at the designated monitoring station when there are Project-related construction activities being undertaken within a radius of 300 m from the monitoring stations. The monitoring frequency should depend on the scale of the construction activities. An initial guide on the monitoring is to obtain one set of 30-minute measurement at each station between 0700 and 1900 hours on normal weekdays at a frequency of once a week when construction activities are underway.

5.6.2 If construction works are extended to include works during the hours of 1900 - 0700, additional weekly impact monitoring shall be carried out during evening and night-time works. Applicable permits under NCO shall be obtained by the Contractor.

5.6.3 In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Action Plan in Table 5.3 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.

5.7 Event and Action Plan for Construction Noise

5.7.1 The Action and Limit levels for construction noise are defined in Table 5.2. Should non-compliance of the criteria occur, action in accordance with the Action Plan in Table 5.3 shall be carried out.

Table 5.2 Action and Limit Levels for Construction Noise

Time Period	Action Level	Limit Level
0700 – 1900 hours on normal weekdays	When one documented complaint is received	75 dB(A)*

Notes:

· If works are to be carried out during restricted hours, the conditions stipulated in the Construction Noise Permit (CNP) issued by the Noise Control Authority have to be followed.

· * 70 dB(A) and 65 dB(A) for schools during normal teaching periods and school examination periods, respectively.
