1.1 Project Background
1.1.1.1 In June 2017, The Chief Executive in Council has agreed in principle to the government proposal to grant a piece of land in Tai Po to Sha Lo Tung Development Company Limited (the Project Proponent) in exchange for its private land in Sha Lo Tung which has high ecological values. Under the non-in-situ land exchange proposal, the piece of land at the Shuen Wan Restored Landfill in Tai Po will be granted to the Project Proponent for the development of a private golf course and the Sha Lo Tung site would be considered by government for active conservation management to avoid degradation and damage for long-term public enjoyment. This land exchange proposal is a unique, exceptional and isolated case, and adding the idea is technically feasible as the private land ownership is largely unified under one entity and both Sha Lo Tung and the land at the landfill site, which has been planned for golf course development, are located in Tai Po.

4 Air Quality
4.1 Introduction
4.1.1.1 The EIA has considered the potential air quality impacts associated with the Project. Based on the assessment results, fugitive dust emission would be the key potential impact during the construction phase. No adverse impact from the Project is anticipated during the operational phase.
4.2.1 Construction Phase
4.2.1.1 Prior to commencement of construction activities, the potential construction dust impacts to nearby receivers should be assessed and documented in a Construction Dust Management Plan. Contractor shall prepare the plan and submit to EPD for approval.
4.2.1.2 During the construction phase, regular watering and other good site practices should be implemented. In particular, a 3m high hoarding of around 110m in length is proposed at the northern boundary of the Project Site in order to minimize potential dust impacts to the receivers in close proximity to the construction site (See Figure 4.1a for proposed extent). All the recommended good practices are summarized in Appendix 4.1a the Environmental Mitigation Implementation Schedule (EMIS).
4.2.2 Operational Phase
4.2.2.1 No adverse impact from the Project is anticipated during the operational phase. Nevertheless, deododouriser equipped with 99.5% odour removal efficiency should be installed at the proposed sewage pumping station (SPS) prior to operation of the Project to minimize any potential odour nuisance.
4.3 Air Quality Monitoring Parameters

4.6.1.4 The ET may, depending on site conditions and monitoring results, decide whether additional monitoring locations shall be included or any monitoring locations could be removed / relocated during any stage of the construction phase.
4.7 Baseline Monitoring
4.7.1.1 Baseline monitoring shall be carried out at all of the designated monitoring locations (see Table 4.1) for at least two weeks prior to the commissioning of major construction works to obtain ambient 1-hour TSP samples. Ambient 1-hour sampling should also be done at least 3 times per day at each monitoring station.
4.7.1.2 During the baseline monitoring, there should not be any major construction or dust generation activities in the vicinity of the monitoring stations. Before commencing baseline monitoring, the ET shall inform the IEC of the baseline monitoring programme such that IEC can conduct on-site audit to ensure accuracy of the baseline monitoring results.
4.7.1.3 In case the baseline monitoring cannot be carried out at the designated monitoring location, the ET shall carry out the monitoring at alternative location that can effectively represent the baseline conditions at the impact monitoring location. The alternative baseline monitoring location shall be agreed with the IEC prior to commencement of baseline monitoring.
4.7.1.4 In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference.
4.7.1.5 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. 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 and air quality criteria, after consultation and agreement with the ER, IEC and EPD.
4.8 Impact Monitoring
4.8.1.1 The ET shall carry out impact monitoring during major construction activities for the Project as specified in Table 4.1. For 1-hour TSP monitoring, the sampling frequency of at least 3 times in every 6 days should be undertaken when the highest dust impact occurs.
4.8.1.2 The monthly schedule of the impact monitoring programme should be drawn up by the ET one month prior to the commencement of the scheduled construction period. Before commencing impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit.
4.9 Action and Limit Levels
4.9.1.1 The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring.

5 Hazard to Life
5.1 Introduction
5.1.1.1 The EIA Report has reviewed the potential hazard to life due to the presence of a hazardous facility nearby (i.e. Tai Po Gas Production Plant(TPGPP)). Based on the design, adverse impacts from potential hazard to life during construction and operational phases are not anticipated.
5.2 Mitigation Measures
5.2.1 Construction Phase
5.2.1.1 Construction of the Project would not induce significant impact to the prevailing risks level of TPGPP. No mitigation measures are therefore required. Notwithstanding the above, precautionary measures including the provision of emergency plan for efficient evacuation and safety trainings (e.g. fire drills) will be implemented during construction phase of the Project. A communication mechanism would be established between the operators of TPGPP and the ER to allow evacuation in case of emergency.
5.2.2 Operational Phase
5.2.2.1 Operation of the Project would not induce significant impact to the prevailing risks level of TPGPP. No mitigation measures are therefore required. Notwithstanding the above, precautionary measures including the provision of emergency plan for efficient evacuation and safety trainings (e.g. fire drills) will be implemented during operational phase of the Project. A communication mechanism would be established between the TPGPP’s operator and the Golf Course’s operator to allow evacuation in case of emergency.
5.3 Environmental Monitoring and Site Audit Requirements
5.3.1 Construction Phase
5.3.1.1 Monitoring and audit requirements are not required for construction phase.
5.3.2 Operational Phase
5.3.2.1 Monitoring and audit requirements are not required for operational phase.
6 Noise
6.1 Introduction
6.1.1.1 The EIA Report has considered the potential noise impacts associated with the Project. Construction noise from the use of powered mechanical equipment during site clearance, site formation works, construction of new ancillary facilities etc. would be the major potential noise impacts during the construction phase. Noise monitoring is proposed to be conducted during construction phase. During the operational phase, adverse noise impact from fixed noise sources is not anticipated. Thus, mitigation measures and monitoring are not required. Notwithstanding, fixed noise commissioning test shall be conducted prior to the operation of the Project to confirm that the relevant standards stipulated in TM-EIAO and Noise Control Ordinance (NCO) would be complied with.
6.2 Mitigation Measures
6.2.1 Construction Phase
6.2.1.1 The EIA Report has recommended construction noise mitigation measures including use of quiet plant and temporary noise barriers, etc. All the proposed mitigation measures are summarized in Appendix 4.1a.
6.2.2 Operational Phase
Fixed Noise Sources
6.2.2.1 For the proposed fixed noise sources which are located near the existing Noise Sensitive Receivers (NSRs), the following noise mitigation measures shall be considered:
· All the pumps should be enclosed inside building structures;
· Proper selection of quiet plant aiming to reduce the tonality at NSRs;
· Installation of silencer / acoustic enclosure / acoustic louver for the exhaust of ventilation system;
· Openings of ventilation systems should be located away from NSRs as far as practicable; 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.
6.3 Noise Monitoring Parameters
6.3.1 Noise Monitoring Parameter for Construction Phase
6.3.1.1 Construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30min) shall be used as the monitoring parameter for the time period between 0700 and 1900 hours on normal weekdays. For all other time periods, Leq (5min) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. A sample data sheet is shown in Appendix 6.1.
6.3.1.2 As supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.
6.3.2 Noise Monitoring Parameter for Operational Phase
6.3.2.1 As fixed plant noise impact during the operational phase is not anticipated, noise monitoring for the operation of the Project is not required. Nevertheless, fixed noise commissioning test should be conducted prior to the operation of the Project.
6.4 Monitoring Equipment
6.4.1.1 As referred to the Technical Memorandum (TM) issued under the NCO, sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement, the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration level from before and after the noise measurement agrees to within 1.0 dB.
6.4.1.2 Noise measurement should be made in accordance with standard acoustical principles and practices in relation to weather conditions.
6.4.1.3 The ET is responsible for the provision, installation, operation, maintenance, dismantle of the monitoring equipment. They 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.
6.5 Monitoring Locations
6.5.1 Monitoring Locations for Construction Phase
6.5.1.1 The most representative and affected NSRs were selected as monitoring stations and details could be referred to the EIA Report. The locations of construction airborne noise monitoring stations are summarised in Table 6.1 and shown in Figure 6.1.

Village House at 53 Ting Kok Road |
6.5.1.2 The ET shall select the monitoring locations from the above table based on the locations of the construction activities and seek approval from ER and agreement from the IEC and EPD to the proposal. The monitoring locations should be chosen based on the following criteria:
· At locations close to the major site activities which are likely to have noise impacts;
· Close to the most affected existing noise sensitive receivers; and
· For monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance to the occupants during monitoring.
6.5.1.3 The monitoring station shall normally be at a point 1m from the exterior of the sensitive receiver building facade and be at a position 1.2m above the ground. If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made to the free field measurements. The ET shall agree with the IEC on the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions.
6.5.1.4 The ET may, depending on site conditions and monitoring results, decide whether additional monitoring locations shall be included or any monitoring locations could be removed/relocated during any stage of the construction phase.
6.6 Baseline Monitoring
6.6.1.1 The ET shall carry out baseline noise monitoring prior to the commencement of the construction works. There shall not be any construction activities in the vicinity of the noise monitoring stations during the baseline monitoring. Continuous baseline noise monitoring for the A-weighted levels Leq, L10 and L90 shall be carried out daily for a period of at least two weeks in a sample period of 5 minutes or 30 minutes between 0700 and 1900, and 5 minutes between 1900 and 0700. A schedule on the baseline monitoring shall be submitted to the ER and IEC for approval before the monitoring starts.
6.6.1.2 In exceptional cases, when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the IEC and EPD to agree on an appropriate set of data to be used as a baseline reference.
6.7 Impact Monitoring
6.7.1 Impact Monitoring for Construction Phase
6.7.1.1 During normal construction working hours (0700-1900 Monday to Saturday), monitoring of Leq, (30min) noise levels shall be carried out at the agreed monitoring locations once every week in accordance with the methodology in the TM issued under NCO.
6.7.1.2 In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Event and Action Plan, 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.
6.7.1.3 The monthly schedule of the impact monitoring programme should be drawn up by the ET one month prior to the commencement of the scheduled construction period. Before commencing impact monitoring, the ET shall inform the IEC of the impact monitoring programme such that the IEC can conduct on-site audit.
6.7.2 Fixed Noise Commissioning Test
6.7.2.1 The maximum allowable sound power levels of the identified fixed noise sources have been predicted in the EIA Report. The Contractor should implement and refine the specified sound power levels as appropriate to ensure compliances with the noise standards stipulated in the TM-EIAO and NCO for the fixed plant operations.
6.7.2.2 The Contractor should also carry out a noise commissioning test for all fixed noise sources before the operation of the Project, in order to ensure compliance of the noise levels with the stipulated noise standards in the TM-EIAO and NCO.
6.8 Action and Limit Levels
6.8.1.1 The ET shall compare the construction noise monitoring results with noise criteria. Table 6.4 shows the noise criteria, namely Action and Limit levels to be used.

7.1 Introduction
7.1.1.1 The EIA Report has assessed the potential water quality impacts associated with the Project. According to the EIA Report, the water quality impact could be minimised with the implementation of mitigation measures. The water quality monitoring programme as discussed below could ensure the implementation of the recommended mitigation measures and provide continue improvements to the environmental conditions. Nevertheless, since the Turfgrass Management Plan would need to be further updated during the detailed design stage, the water quality monitoring parameters and other relevant parts should be subject to review throughout the course of the detailed design stage, subject to determination from the review findings and subject to agreement with relevant authorities.
7.2 Mitigation Measures
7.2.1 Construction Phase
7.2.1.1 During the construction phase, the EIA Report has recommended mitigation measures including good site practices to control construction site runoff, portable chemical toilets to collect the sewage from workforce, etc. All the mitigation measures are summarized in Appendix 4.1a.
7.2.2 Operational Phase
7.2.2.1 During the operational phase, the EIA report has recommended to design a drainage system to withstand rainstorms of a 50-year return period to reduce the chance of surface overflow, design water storage tanks with a total volume of 30,000m3 to avoid and limit uncontrolled surface runoff and soil erosion, a proper location of the outfall from water storage tanks to minimise the water quality impact to the Water Sensitive Receivers (WSRs) in the vicinity from surface runoff, etc. Additional provisions including dual feed power supply or backup power supply facilities, standby pumps and using sewage tanker vehicles to remove sewage from the SPS to existing public sewer manhole located in front of main entrance of golf development on Ting Kok Road are suggested to be considered for the SPS to avoid the occurrence for emergency bypass.
7.3 Water Quality Monitoring Parameters
7.3.1 Construction Phase

7.3.2.2 The water quality of the operational phase should be monitored to ensure the compliance of relevant WQO standards at Tolo Harbour and Channel Water Control Zone, EPD guideline values and discharge standards and the criteria established in the EIA Report. The Project Proponent should review if the monitoring programme would need to be continued 2 months before the end of the 1-year monitoring period and agree with EPD.
7.3.2.3 The measurements shall be taken at all designated monitoring stations on a bi-weekly basis for the first 12 months. The frequency will be reviewed for the remaining 12 months and subject to EPD’s approval. The water monitoring should cater the tidal effects. At least one sampling at mid-flood tides and one sampling at mid-ebb tides shall be conducted for each monitoring.
7.3.2.4 In case the Project Proponent wishes to change the fungicides and insecticides to be applied at the proposed golf course during the monitoring period, the Project Proponent shall update the monitoring parameters, detection limits and analytical methods accordingly. The Project Proponent should seek approval from EPD before changing the monitoring parameters.
7.3.2.5 Replicate samples collected from each independent sampling event shall be collected to ensure a robust statistically interpretable database. Samples should be determined by an accredited laboratory.
7.3.2.6 Other relevant data shall be recorded, including monitoring location / position, time, water depth, tidal stages, weather conditions and any special phenomena or work underway at the Project Site.

7.4.6 Water Depth Detector
7.4.6.1 A portable, battery-operated echo sounder should be used for water depths determination at each designated monitoring station. The detector can either be hand-held or affixed to the bottom of the work boat, if the same vessel is to be used throughout the monitoring programme.
7.4.7 Water Sampling Equipment
7.4.7.1 Proper water samplers are required for monitoring. It should comprise a transparent PVC cylinder, with a capacity of not less than 2 litres, which can be effectively sealed with latex cups at both ends. The sampler should have a positive latching system to keep it open to prevent premature closure until released by a messenger when the sampler is at the selected water depth (for example, Kahlsico Water Sampler or an approved similar instrument).
7.4.8 Sample Containers and Storage
7.4.8.1 Water samples for SS should be stored in high density polythene bottles with no preservative added, while those for fungicides and insecticides should be stored in amber glass bottles with no preservative added, packed in ice (cooled to 4°C without being frozen) and shipment to the testing laboratory. The samples shall be delivered to the laboratory of collection and be analysed as soon as possible after collection.

The purpose of impact monitoring is to ensure the implementation of the recommended mitigation measures, provide effective control of any malpractices, and to identify any further need for the additional mitigation measures during operational phase of the proposed golf course. A 1-year monitoring period is proposed for the operational phase on a bi-weekly basis, at mid-flood and mid-ebb tides. The Project Proponent should review if the monitoring programme would need to be continued 2 months before the end of the 1-year monitoring period and agree with EPD.
7.8.2.2 In case of project-related exceedances of Action and/or Limit Levels, the impact monitoring frequency shall be increased according to the requirement of Event and Action Plan, except for the monitoring station WM-3. The details of Event and Action Plan will be discussed in Section 7.10.
7.8.2.3 Table 7.7 below summarizes the proposed water quality monitoring programme for impact monitoring during operational phase.

8.1 Introduction
8.1.1.1 The quantity and timing for the generation of waste during the construction phase have been estimated in the EIA Report. Measures including the opportunity for on-site sorting, reusing excavated materials etc., are devised in the construction methodology to minimise the surplus materials to be disposed of off-site. Chemical waste should be collected by licensed chemical waste collectors for proper disposal.
8.2 Mitigation Measures
8.2.1 Construction Phase
8.2.1.1 All the proposed mitigation measures during construction phase are stipulated in the EIA Report and summarised in Appendix 4.1a.
8.2.1.2 Waste will be handled in accordance with the relevant legislation and guidelines and with the implementation of the proposed mitigation measures, no adverse environmental impacts from waste management are anticipated. EM&A is required for waste management during the construction phase only and the effective management of waste arising during the construction phase will be monitored through the site audit programme. The aims of the waste audit are:
· to ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner; and
· to encourage the reuse and recycling of material.
8.2.1.3 A trip-ticket system should be operated to monitor all movements of non-inert C&D materials for disposal at landfill and chemical wastes which will be collected by licensed chemical waste collectors to licensed facilities for final treatment and disposal. Recommendations have been made in the EIA Report to ensure proper treatment and proper disposal of these wastes and summarised in Appendix 4.1a.
8.2.1.4 All dump trucks engaged on site should be equipped with Global Positioning System (GPS) or equivalent system for tracking and monitoring of their travel routings and parking locations to prohibit illegal dumping and landfilling of C&D materials. Closed-circuit television (CCTV) will be installed at the site entrances to monitor and estimate the quantity of waste leaving the site. Records and analysis of data collected by the mentioned GPS, CCTV and/or equivalent systems should be kept.
8.2.2 Operational Phase
8.2.2.1 The types and quantities of waste that would be generated during the operational phase have been assessed. General refuse generated from the Project should be collected with lidded bins and at least daily collection should be arranged by the waste collector as stated in the EIA Report. If any chemical waste is to be generated from the operation of the Project, the operator shall register as a Chemical Waste Producer with EPD and manage the chemical waste in accordance with Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C). Furthermore, organic waste such as grass clippings is encouraged to be used for composting on-site through the 3-Bin Composting System. With proper management, it is anticipated there would not be any insurmountable impacts during the operational phase.
8.3 Environmental Monitoring and Site Audit Requirements
8.3.1 Construction Phase
8.3.1.1 The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant licenses / permits for waste disposal. The ET shall ensure that the Contractor has obtained from the appropriate authorities the necessary waste disposal permits or licenses including:
· Chemical Waste Collection License / Chemical Waste Disposal License under the Waste Disposal Ordinance (Cap 354);
· Chemical Waste Producer Registration;
· Dumping License under the Land (Miscellaneous Provisions) Ordinance (Cap 28);
· Water Pollution Control Ordinance License under the Water Pollution Control Ordinance.
8.3.1.2 The Contractor shall refer to EPD’s Guidance Notes for License Application when applying for the license / permit and the ET shall refer to these Guidance Notes for auditing purposes.
8.3.1.3 Regular audits and site inspections should be carried out during construction phase by the ET to ensure that the recommended good site practices and other mitigation measures recommended in the EIA Report and in Appendix 4.1a are properly implemented by the Contractor. The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal. Apart from site inspection, documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.
8.3.1.4 The requirements of the environmental audit programme are set out in Section 14 of this Manual. The audit programme will verify the implementation status and evaluate the effectiveness of the mitigation measures.
8.3.2 Operational Phase
8.3.2.1 As it is anticipated that there would not be any insurmountable impacts during the operational phase, monitoring and audit requirements are not required.
9.1 Introduction
9.1.1.1 The EIA Report has documented the land contamination issues associated with the Project.
9.2 Site Investigation for Potentially Contaminated Areas
9.2.1.1 As outlined in Section 8 of the EIA Report, based on the desktop review findings of selected aerial photos, the information collected during site survey, from the operator of the current Golf Driving Range as well as EPD and Fire Services Department (FSD), the storage/ workshop area is identified as the only potential contaminated site within the boundary of the Project and the works of the Project. Nevertheless, the land contamination potential at the storage/ workshop area is low.
9.2.1.2 Project Proponent (PP) is recommended to conduct further land contamination assessment at the storage/ workshop area at later stage of the Project after the area within the boundary of the Project and the works of the Project is handed over to the PP. Further land contamination assessment should include site re-appraisal, submission of Land Contamination Review (LCR) or Contamination Assessment Plan (CAP), Site Investigation (SI) and submission of Contamination Assessment Report (CAR), if necessary.
9.3.1 Construction Phase
9.3.1.1 PP is recommended to conduct further land contamination assessment at the storage/ workshop area at later stage of the Project after the area within the boundary of the Project and the works of the Project is handed over to the PP. If land contamination is confirmed, a Remediation Action Plan (RAP) should be submitted to formulate viable remedial measures. Possible remediation methods include air sparging, biopile, stabilisation / solidification, thermal desorption, etc. The contaminated land should then be remediated according to the approved RAP, and a Remediation Report (RR) should be submitted to demonstrate the land has been remediated adequately.
9.3.2 Operational Phase
9.3.2.1 The operation of the Project is regarded as a potential contaminated use in accordance with EPD’s Practice Guide for Investigation and Remediation of Contaminated Land. The application of agrochemicals including fertilizer, pesticides and herbicides as well as accidental chemical spillages may cause land contamination issues.
9.3.2.2 Agrochemical Management
9.3.2.3 Agrochemicals including pesticides would be applied at the Project Site to provide a suitable growth environment for the turf, and avoid any potential public health impacts arising from the insects. Economic and environmental approach to the use of agrochemicals is by minimizing the use of agrochemicals, while maintaining the viability of turf grass and inhibit growth of pathogens. As such, the application, handling and storage of pesticides should follow AFCD’s Code of Practice for the Safe and Efficient Use of Pesticides on Sports Turf, A Guide to Labelling of Pesticide and Safety Guidelines for Storage of Pesticides respectively. The storage of pesticides shall follow the Pesticides Ordinance (PO) (Cap. 133), Dangerous Goods Ordinance (Cap. 295) and Gas Safety Ordinance (Cap. 51).
9.3.2.4 Any disposal of agrochemicals including pesticides shall follow the Waste Disposal Ordinance (Cap. 354), Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354C) and A Guide to the Chemical Waste Control Scheme promulgated by EPD. The operator of the Project shall be registered as a Chemical Waste Producer and shall only engage a licensed waste collector for the collection and removal of chemical waste.
Chemical Spillage Control
9.3.2.5 In case of any chemical spillage, the operator should follow the instruction of the labels and take precautionary measures before handling the spillage. In the absence of specific instruction for handling the spillage of the product, the following procedures may be followed:
· Contain and cover the spillage with double its volume of inert absorbent e.g. sand, sawdust or soil;
· After the spill has been absorbed, sweep or shovel this up thoroughly;
· Put all contaminated debris in a sealed and marked container or large heavy duty plastic bag and place this in a secure area to await safe disposal;
· Water used to clean containers, or any contaminated liquids should under no circumstances be allowed to enter drains or watercourses;
· Disposal of contaminated liquids and debris should be carried out only after consultation with EPD.
9.3.2.6 With reference to EPD’s Code of Practice for the Packaging, Labelling and Storage of Chemical Wastes, in incidents where the spillage may result in significant contamination of an area or risk of pollution, EPD should be informed immediately.
Environmental Conscious Turfgrass Management Plan
9.3.2.7 In order to prevent the agrochemicals from contaminating the land, an environmental conscious Turfgrass Management Plan (TMP) would be developed during the detailed design stage. The outline of the environmental conscious TMP is presented in Section 2.7 of the EIA Report. Details on the application, handling and storage of agrochemicals as well as measures to be carried out in the occurrence of chemical spillage will be provided in the TMP.
9.4 Environmental Monitoring and Site Audit Requirements
9.4.1 Construction Phase
9.4.1.1 Environmental monitoring and site audit are not required for construction phase.
9.4.2 Operational Phase
9.4.2.1
Environmental monitoring and site audit are not required for operational
phase.
10 Landfill Gas Hazards
10.1 Introduction
10.1.1.1 The EIA Report has documented the landfill gas (LFG) hazards associated with the Project. According to the EIA Report, with the provision of mitigation measures, adverse impacts on the targets within the Project are not anticipated.
10.2 Mitigation Measures
10.2.1 Construction Phase
10.2.1.1 All the proposed mitigation measures during construction phase are stipulated in the EIA Report and summarised in Appendix 4.1a. These mitigation measures include appointment of Safety Officer, site safety measures, landfill gas monitoring and emergency management.
10.2.2 Operational Phase
10.2.2.1 During the operational phase, the following protective and precautionary measures will be provided/implemented wherever practicable:
· Active gas control (e.g. mechanical ventilation system);
· Semi-active gas control (e.g. wind scoops);
· Passive gas control (e.g. gas-proof membranes, compacted high density concrete, ventilation by natural air movement);
· Gas detection system;
· Good site management; and
· Entry safety procedures for confined spaces.
10.2.2.2 Subsurface services within the Consultation Zone shall be so designed and installed to avoid the potential vertical or lateral migration of LFG. All the proposed mitigation measures during operational phase are stipulated in the EIA Report and summarised in Appendix 4.1a.
10.3 Environmental Monitoring and Site Audit Requirements
10.3.1 Construction Phase
10.3.1.1 Periodically during ground-works construction, the works area should be monitored by the site Safety Officer for oxygen, methane and carbon dioxide gas concentrations using appropriately calibrated portable gas detection equipment. Routine monitoring should be carried out in all excavations, manholes, chambers and any other confined spaces that may have been created. The monitoring frequency and areas to be monitored should be set down prior to commencement of ground-works by the Safety Officers. The monitoring requirement of excavations stated in the Landfill Gas Hazard Assessment Guidance Note (EPD/TR8/ 97) sections 8.25 to 8.27 will be followed. All measurements of LFG should be recorded and documented by a standard record form to be approved by EPD. The form will detail the location, time of monitoring and equipment used, together with the gas concentrations measured to ensure all relevant data are recorded. LFG monitoring during construction phase will be reported in the monthly EM&A Reports.
10.3.1.2 The gas detection equipment should be appropriately calibrated and able to measure the following gases in the ranges indicated below:
Methane 0-100% LEL and 0-100% v/v
Carbon dioxide 0-100%
Oxygen 0-21%
10.3.1.3 Monitoring should be performed properly to make sure that the area is free of LFG before any man enters into the area.
10.3.1.4 All measurements in excavations should be made with the extended monitoring tube located not more than 10mm from the exposed ground surface. The monitoring should be undertaken by the Safety Officer.
10.3.1.5 For excavations deeper than 1m, measurements should be carried out:
· at the ground surface before excavation commences;
· immediately before any worker enters the excavation;
· at the beginning of each working day for the entire period the excavation remains open; and
· periodically throughout the working day whilst workers are in the excavation.
10.3.1.6 For excavations between 0.3m and 1m deep, measurements should be carried out:
· directly after the excavation has been completed; and
· periodically whilst the excavation remains open.
10.3.1.7 For excavations less than 0.3m deep, monitoring may be omitted, at the discretion of the Safety Officer or other appropriately competent environmental specialist.
10.3.1.8 Depending on the results of the measurements, actions required will vary and should be set down by the Safety Officer or other appropriately environmental specialist. As a minimum, these should encompass those actions specified in Table 10.1.

10.3.1.9 Upon completion of the works, a competent professional person representing the Project Proponent shall confirm in writing to EPD that all the recommended LFG protection measures for the Project have been properly incorporated, installed and implemented. This could be in form of a report with photos showing the installation of membrane, installation of gas detection system, etc. as well as the relevant as-built drawings related to LFG protection measures.
10.3.2 Operational Phase
10.3.2.1 Always-on gas detection system would be provided at all rooms, houses and indoor environment such as car park, lift and staircases, offices, golf shop, changing rooms, staff quarters and overnight accommodation etc. which will be occupied by medium and highly sensitive targets and be involved in the long-term uses. The gas detector is used to monitor the methane, carbon dioxide and oxygen gas concentrations and should be calibrated on a regular basis according to the manufacturers’ recommendations. The sensors detect methane, carbon dioxide and oxygen gases by the catalytic oxidation or infra-red principles, and pass data back to a control panel by electrical cabling. Appendix 9.6b of the EIA report shows the schematic of automatic gas detection system. In the event of a power failure, the detectors should have an 8-hour battery back-up system, and the procedures should indicate for manual monitoring in the stations in the event of prolonged power failure (of longer than 8 hours).
10.3.2.2 The gas detection system should include an alarm set at the trigger levels as mentioned in Table 10.2 in order to give warning to the public and evacuate sensitive targets from buildings. The gas detection system will also interlock with the mechanical ventilation system. In case the gas concentrations exceed the trigger levels, mechanical ventilation system will be operated to restore methane, carbon dioxide and oxygen levels to safe concentrations as soon as possible.

· Carbon dioxide: 1.5% v/v above natural background
10.3.2.4 In case the above limits are exceeded, EPD and Landfill Contractor should be informed. Specialist should also be sought to review the existing precautionary measures to ensure the continuous safety of the site.
11 Ecology
11.1 Introduction
11.1.1.1 The EIA has evaluated the ecological impacts of the Project and recommended ecological mitigation measures to avoid, minimize and compensate the impact arising from the Project.
11.2.1.1 The proposed mitigation measures for ecological impacts are summarised in Appendix 4.1a.
11.2.2 Avoidance
Avoidance of recognised sites of conservation importance
11.2.2.1 All the recognised sites of conservation importance, including Country Parks, Sites of Special Scientific Interest (SSSIs), Ecologically Important Streams (EISs), and existing / proposed Marine Parks have been avoided and will not be encroached by any developments under the present Project during both construction and operation phases.
Avoidance of marine works during construction
11.2.2.2 There will be no marine works and marine traffic during the construction and operational phases of the Project to avoid potential impact on the marine habitats of conservation importance (e.g. Ting Kok SSSI) and marine ecological resources in the vicinity of the Project. In particular, no modification of existing seawall and no dredging works would be anticipated for the Project.
Avoidance of effluent discharge to Tolo Harbour
11.2.2.3 The ancillary facilities including food and beverage, offices, etc. within the Project would inevitably generate some sewage during their daily operation. Although the number of population and hence quantity of sewage generated is small (i.e. only about 500m3/day of Average Dry Weather Flow (ADWF)), it still needs to be properly handled in order to avoid any adverse impacts on the neighbouring Tolo Harbour water body. The generated effluent will be conveyed to TPSTW for proper treatment and disposal, hence discharge of effluent would be avoided as far as practicable.
11.2.3 Minimization
11.2.3.1 Several measures will be implemented to minimise potential impacts.
Minimization of impacts due to loss/disturbance of night roosts of Collared Crow and Black Kite
11.2.3.2 The following measures will be implemented to minimise impacts due to loss/disturbance of night roosts of Collared Crow and Black Kite:
· Preservation of some existing tree groups to minimise the loss;
· Erection of fencing without foundation surrounding these tree groups to minimise the construction phase impact;
· Phasing of construction works and works areas to minimise duration of impact; and
· Restriction of construction works hours to minimise the construction phase impact.
11.2.3.3 Tree Preservation: Some existing tree groups used by Collared Crow and Black Kite as night roosts will be preserved in order to minimise the potential impact of loss of roosting sites. Reduction of available plantation as roosting sites for Collared Crow and Black Kites during construction phase is inevitable due to site constraints. After taking into account the conservation need, the engineering constraints, and the requirements of a viable golf course design, the total area size of preserved existing tree groups is about 6.1 ha, and the major tree group at the south side as the night roost site is about 1.2 ha. Considering that both species roost in groups on limited number of trees (the roosting individuals of Collared Crow usually roosts only on a few trees, mostly 3-5, trees, and Black Kite individuals as observed also utilized less than 20 number of trees) and the roosting birds do not display strong fidelity to particular spots along the plantation at the waterfront for roosting, the preserved trees are hence of considerable size for serving as roosts and also screening and buffer during both construction and operational phase.
11.2.3.4 Several patches of plantation tree groups along the eastern boundary of the Project Site, which also include trees used by Collared Crow and Black Kite as night roosts, will also be preserved as well. Other major preserved tree groups include plantations along the western boundary of the Project Site will also be preserved as alternative roost sites for Collared Crow and Black Kite and also to provide visual screening from the industrial estate. The heights of these trees are similar to those used by Collared Crow and Black Kite as night roosts, and the tree species used as roosts is also present in these preserved plantations.
11.2.3.5 Fencing: Protective fencing without foundation will be erected to protect the preserved tree group from construction disturbance. Upon completion of construction, the area will be fenced off. Additional screening planting would also be proposed in the future detailed planting plans adjacent to the preserved tree group to expand the plantation area size as roosting sites for Collared Crow and Black Kite.
11.2.3.6 Phasing of Construction Works: Construction phasing is designed to minimise the duration of possible indirect disturbance to the major preserved tree group as roost sites. Construction activities in the Project Site will be implemented by phases. This will enable existing plantation trees to be lost gradually, and new planting will also be provided gradually during the construction, rather than after all construction is finished as in other projects. Upon completion of site formation at each phase, landscape planting will be implemented immediately before the beginning of next phase such that new tree groups aiming for roosting site provision will be planted before site clearance in the next phase. Extensive new tree planting is proposed under Landscape Impact Assessment of the present EIA and the new tree groups will cover about 10 ha. The new trees will be planted in patches or several rows, to allow the future tree groups suitable for bird roosting. Heavy standard trees (or mature-size trees where possible) will be included in the planting list to facilitate the establishment of new tree groups as early as possible.
11.2.3.7 The construction site will be divided into three areas (i.e. northern, middle and southern in Area 1, 2 and 3 respectively) and the major earth works in each area will be conducted separately in three phases, starting from landward side and without overlapping. Such that the roosting habitats will not all be lost in one time, but by phases. No roost site used by either Collared Crow or Black Kite was recorded in the works area of Area 1 during the surveys, so no impacts to the roosting colonies are anticipated during Area 1 construction, and the roosting habitats in Area 2 and Area 3 will not be impacted in one time, but by phases. Site formation of the area near the major preserved tree group would fall under the last phase (Area 3) of construction.
11.2.3.8 Restriction of Construction Works Hours: During construction phase, working hours will be restricted to minimise potential disturbance to utilisation of the preserved plantations by Collared Crow and Black Kite as night roosts. Construction hours will also be restricted to daytime when Collared Crow and Black Kite mainly use areas outside the Project Site. While the normal works hours are 0700-1900 hrs, work hours of powered mechanical equipment for Area 3 of the Construction Programme (i.e. the southern part of the Project Site, near the major preserved tree group), the ancillary facilities (including part of the water storage tanks and traffic along the existing access road), and the eastern part of Area 2 (near other preserved tree groups) will be restricted to at least one hour before sunset, following the proposed restriction hours derived from the earliest sunset time in each month between 2018 and 2020 (source: Hong Kong Observatory) (see Table 10.9.1 of the present EIA). The proposed restriction of works hours would slightly extend the construction programme as a trade-off, but would provide sufficient time for powered mechanical equipment to halt well before the earliest sunset time when Collared Crow and Black Kite might be in search of a roost site. Therefore, given these multiple protection measures, the potential construction disturbance to the preserved tree group for Collared Crows and Black Kites would be minimised.
11.2.3.9 Reduce Impact from Human Activities: In contrary to typical golf courses which would arrange the golf driving range immediately next to their ancillary facilities, the current layout has opted to locate the golf driving range away from the ancillary facilities by at least 250m in order to preserve the major tree group utilised as night roost sites and allow buffer from human activities. The adjacent golf hole alignments has also been modified, and the size of the proposed driving range has been substantially reduced, from 25,000m2 to 20,000m2 to maximise the area size of this major tree group to be preserved. The current layout of has strategically positioned the golf driving range in order to direct the golf shots towards the north, and lighting will also be limited to the driving bay area. This would minimise the potential disturbance on the major preserved tree group, in the cost of compromising the view enjoyed by the users at the golf driving range.
Minimising Impact on Protected Plant Species
11.2.3.10 The two individuals of Aquilaria sinensis in conflict with site formation will be preserved in-situ. Should further individuals of Incense Trees be found and having direct conflict with the golf course layout, transplantation will be recommended to minimize the potential impact.
Minimising Impact on Aquatic/Marine Habitats
11.2.3.11 Good site practices as described in Practice Note for Professional Persons on Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC PN 1/94) should be implemented where applicable to avoid potential adverse water quality impacts.
11.2.3.12 A temporary drainage system would be installed around the site perimeter to intercept all construction runoff and divert it to the water storage tanks during the construction phase. Construction site surface runoff collected by the storage tanks will undergo sufficient sedimentation before discharge to Tolo Harbour.
11.2.3.13 Mitigation measures stated in the water quality section, including dikes or embankments for flood protection, silt/sediment traps, oil interceptors, should be implemented wherever appropriate.
11.2.3.14 Construction works should be programmed to minimize surface excavation works during the rainy seasons. All exposed earth areas should be vegetated as soon as possible after earthworks have been completed. If excavation of soil cannot be avoided during the rainy season, or at any time of year when rainstorms are likely, exposed slope surfaces should be covered by tarpaulin or other means.
11.2.3.15 All construction materials at temporary storage areas will be covered with tarpaulins or similar fabric during rainstorms. Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system.
11.2.3.16 A drainage system which can withstand rainstorms of a 50-year return period will be designed for the Project during operational phase. The surface runoff from turfgrass and landscaped areas will be collected by surface channels and diverted to the water storage tanks with a total volume of 30,000 m3.
11.2.3.17 Mechanical methods (hand weeding) of removing turfgrass weeds will be the primary means of weed control. The amount of herbicides to be applied will be minimised through the implementation of the environmental conscious Turfgrass Management Plan.
11.2.4 Compensation
Compensation for Loss of Plantation
11.2.4.1 There will be extensive plantation areas with higher plant diversity and number of native species in the future golf course. Bird-attracting and butterfly-attracting plant species will be planted to enhance the utilisation of the Project Site by birds and butterflies. The new plantation areas and planting will provide higher ecological functions than the existing plantation which is of low diversity.
Compensation for Loss of Roosting Sites
11.2.4.2 To mitigate the loss of roosting sites for Black Kites and Collared Crow, heavy standard trees (or mature-size where possible) of native species with large growth form including Hibiscus tiliaceus, Liquidambar formosana, Schima superba and Aquilaria sinensis will be planted in patches/tree belts along the access road and near the waterfront to quickly provide established tree groups. Casuarina equisetifolia is the tree species most used for roosting on site. Besides intentional preservation of some existing Casuarina equisetifolia tree individuals, the proposed planting list for the new trees also includes Casuarina equisetifolia though it is an exotic species. More potential roosting sites will be available as the landscape tree plantings mature over time.
11.3 Environmental Monitoring and Site Audit Requirements
11.3.1 Monitoring for Utilisation of Roosting Sites during Construction Phase
11.3.1.1 During construction phase, roost surveys should be conducted on the Project Site to monitor utilisation of the preserved and/or the newly planted tree groups by Collared Crow and Black Kite.

11.3.3.1
Site inspections and water quality monitoring during construction
phase shall be carried out to monitor any malpractice leading to deterioration
of water quality of the surrounding which may in turn affect marine
ecology. Water monitoring are also required during operational phase to
verify the prediction of no anticipated adverse impact.
12 Fisheries
12.1 Introduction
12.1.1.1 The EIA has evaluated the potential fisheries impact and recommended water quality mitigation measures to avoid and minimise the impact arising from the Project.
12.2 Mitigation Measures
12.2.1.1 No fisheries specific mitigation measures and monitoring would be required and mitigation measures recommended in the water quality impacts will also minimise any adverse impacts on fisheries.
12.2.2 Construction Phase
12.2.2.1 Though fisheries impact is unlikely, precautionary practices to prevent fisheries impacts due to the deterioration of marine water quality should be implemented. Good site practices as listed in the water quality section should be maintained to mitigate the surface runoff generate from the construction works.
12.2.3 Operational Phase
12.2.3.1 During operational phase, the chance of affecting the water quality by the residual agrochemicals and fertilizers in turf area runoff should be minimised by the provision of storage tanks as mentioned in the water quality section.
12.3 Environmental Monitoring and Site Audit Requirements
12.3.1 Construction Phase
12.3.1.1 Site inspections during construction phase shall be carried out to monitor any malpractice leading to deterioration of water quality of the surrounding which may in turn affect the fisheries resources. Site inspection shall be undertaken by the ET at least once per week during the routine environmental audit as detailed in Section 14. During construction phase, the proposed water quality monitoring programme stated in Section 6 of the EIA report will include the closest FCZ (i.e. Yim Tin Tsai FCZ).
12.3.2 Operational Phase
12.3.2.1 As there is no anticipated adverse impact during operational phase, monitoring and audit requirements are not required. Nevertheless, water quality monitoring and audit will be conducted during the operational phase to ensure there will not be any adverse impact on fisheries. The proposed water quality monitoring programme stated in Section 6 of the EIA report will include the closest FCZ (i.e. Yim Tin Tsai FCZ).
13 Landscape and Visual
13.1 Introduction
13.1.1.1 The EIA has recommended that EM&A for landscape and visual resources is undertaken during the design, construction and operational phases of the project. The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that any potential conflicts between the proposed landscape measures and any other works of the Project would be resolved at early as practical without affecting the implementation of the mitigation measures.
13.1.1.2 The proposed mitigation measures of landscape and visual impacts are summarised in Appendix 4.1a for both Scenario 1 and Scenario 2 and shown on Figure 13.1.1 to Figure 13.27.2. These measures proposed will be incorporated in the landscape, building and engineering design during detailed design phase. The construction phase mitigation measures will be adopted and audited from the commencement of construction throughout the entire construction period. Mitigation measures for the operational phase will be adopted during the detailed design and be built as part of the construction works so that they are in place on commissioning of the Project..
13.2 Baseline Monitoring
13.2.1.1 Baseline monitoring mainly comprises of checking and updating of any change on preserved trees within the Project Site due to further development and implementation of the Project.
13.2.1.2 The baseline monitoring shall be carried out by the ET and audited by Architect, Engineer, Landscape Architect or a competent person, as a member of the ET. The qualification of proposed auditor shall be submitted to the ER for approval and agreed with the IEC the Landscape Mitigation Measures to be monitored.

Implementation of Mitigation Planting and Planting Species Selection - Replanting of existing / disturbed vegetation will be undertaken at the earliest possible stage of the construction phase of the Project. Native or locally adopted tree species to enhance the biodiversity of the ex-landfill site shall be predominantly utilised. Mature trees would be planted along the proposed access road. Species will be strategically selected, which will be suitable for golf course and not interfere with golf playing and players’ safety. Proposed mitigation planting shall not only be limited to conventional amenity planting, but also consider alternative greening measures such as vertical greening for screening and softening of the built structures such as retaining wall and green roof on built structures for enhancing the visual amenity. Small shrubs, climbing plants, turf and groundcover shall be used in specific locations where technically feasible. |

Transplantation of Existing Trees – Some specimens which have relatively higher amenity value and technically suitable will be considered for transplanting. The final recipient site will be in planting areas within the Project Site and integrated with preserved trees. These trees continue their contribution to the local landscape context as well as the future recreational landscape. The transplanting proposal is subject to review at detailed design stage and seeks for the approval from the relevant government departments in accordance with LAO PN No. 7/2007 and 7/2007A Tree Preservation and Tree Removal Application for Building Development in Private Projects. The implementation programme for the proposed works will reserve enough time for the advanced tree transplanting preparation works to enhance the survival of the transplanted trees. |

Roadside and Amenity Planting –The planting proposals will predominantly utilise native or locally adopted tree species, supplement with ornamental species and broadleaf trees in combination of wind and salinity tolerant plant species along access road. A terraced planter with trees / shrubs / trailing plants will be adopted all along the seashore of the eastern boundary to create landscape buffer to soften the development edge. It will form a continuous landscape buffer at the periphery of the Project Site in combination with tree preservation proposal. Enough soil depth of 1200mm will be reserved for tree planting area to ensure healthy planting establishment. High canopy clearance tree planting will be utilised alongside of access road and not to interfere the EVA requirement and vehicular traffic. Larger size of tree stock will be planted at strategic location to create instant greening effect and landscape vista. The implementation of new planting shall be undertaken as soon as technically feasible after completion of road and building works upon works completion in phase and planting area are ready to ensure the effectiveness of this mitigation during operational phase. |

Compensatory Planting Proposals – As the works are largely located within the Project and along excess road, the planting proposals have sought to utilise all of the available and suitable space for new trees, whips and shrub planting to create a comprehensive landscape framework which is connected to areas of retained and preserved vegetation and designed to integrate the proposals within their future recreational landscape setting. The new planting will be maintained in accordance with good horticultural practice in order to realise the objectives of the mitigation measures. This includes the replacement of defective and invasive plant species in the new planting areas to enhance the aesthetic, landscape and ecological quality of the context. The compensatory planting proposal will be developed at detailed design stage in accordance with the requirements listed in the LAO PN No. 7/2007 and 7/2007A ‘Tree Preservation and Tree Removal Application for Building Development in Private Project’. New tree planting will utilise heavy standard size trees at selected area as accent, standard to light standard size trees in general landscape and roadside planting areas. Smaller planting stock will be used on slope and landscape buffer. Figure 13.1 to Figure 13.6 shows the indicative tree planting locations that will create an instant greening and screening effect to the Project. Based on a preliminary estimation, the planting proposal would achieve replanting ratio of approximately 1:1 (Total number of tree loss: Total number of compensatory trees and whips) in terms of quantity upon the completion of replanting works. Proposed compensatory planting consists of 4,180 trees and 4,818 whips. This replanting ratio has been maximised in balance with the planting and safety requirement for golf course. The development has sought to preserve approximately 2,200 existing trees (19.6%) through retention in their current locations or tree transplanting and plant 4,180 compensatory trees and 4,818whips. Upon the completion of the tree preservation and planting proposal, the Project could accommodate approximately 11,198 trees (including 4,818 whips on slope) in combination of tree preservation and new tree planting, which will formulate a landscape context with good quality. The tree preservation and planting proposal within this green recreation facility will cover the loss of re-instated vegetation on land fill site. The above recommendations are subject to change at detailed design stage. The findings and recommendations on existing trees are subject to review at detailed design stage and a tree felling and transplanting application will be prepared in accordance with LAO PN 7/2007 and 7/2007A Tree Preservation and Tree Removal Application for Building Development in Private Projects and submitted to DLO for approval. |

Responsive Design of Buildings – The design of the proposed building structures, access road and utility facilities will incorporate features as part of visual mitigation measures including: Integrated design approach Responsive design of built structures considered the location of ancillary facilities and utilities. The disposition and height profile of the buildings and above ground utilities structures at less visually prominent location respond to the seashore context. Design measures include the low profile and small building mass to reduce the apparent visual mass and to enhance the sense of visual integration with the existing low profile context. Building Treatment The architectural design seeks to reduce the apparent visual mass of the structures further through the use of recessive colour palette. Incorporation of alternative greening measures such as green roof /vertical greening on built structures where condition allows and particularly at where fronting to the public realm and waterfront.

13.5 Environmental Monitoring and Site Audit Requirements
13.5.1.1 Audits will be carried out during construction phase to ensure all the recommended landscape and visual mitigation measures in the EIA are properly and effectively implemented and to ensure compliance with the intended aims of the measures. The EM&A comprises of monitoring and auditing of proper site management to reduce visual nuisance, the protection of preserved and transplanted trees, advance tree transplanting and mitigation planting works, the implementation and establishment of compensatory planting through site audit programme. Site inspections should be undertaken by the ET at least twice a month during the construction period. The audit will be undertaken by a member of the ET who is a certified arborist or who has tree survey relevant experiences not less than 1 year for monitoring and auditing the landscape works, monthly during the construction period (construction phase) and quarterly during the planting establishment period (operational phase).
13.5.1.2 A qualified softworks contractor will be employed for the implementation of tree protection and transplanting works, landscape works and the subsequent planting establishment works. The planting works will be conducted as soon as technically feasible upon the completion of construction in phases and when the planting areas are ready for receiving plants. At least 12 months establishment period should be provided for all planting works.
13.5.1.3 The landscape and visual baseline will be determined with reference to any tree survey report and the landscape and visual impact assessments included in the EIA and subsequent Government approval of tree treatment and landscape works.
13.5.1.4 The extent of works of the Project should be regularly checked. Any trespass by the Contractor outside the limit of the works, including any vandalism/damage by inclement weather to preserved and transplanted trees shall be recorded.

14 Site Environmental Audit
14.1 Site Inspection
14.1.1.1 Site inspection provides a direct means to initiate and enforce specified environmental protection and pollution control measures. These shall be undertaken routinely to inspect construction activities in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented. Site inspection is one of the most effective tools to enforce the environmental protection requirements at the works area.
14.1.1.2 The ET shall be responsible for formulating the environmental site inspection programme as well as the deficiency and action reporting system, and for carrying out the site inspections. The proposal for rectification, if any, should be prepared and submitted to the ET Leader and IEC by the Contractor.
14.1.1.3 Regular site inspections shall be carried out and led by the ER and attended by the Contractor and ET at least once per week during the construction phase. The areas of inspection shall not be limited to the environmental situation, pollution control and mitigation measures within the site. It should also review the environmental conditions of locations outside the works area which is likely to be affected, directly or indirectly, by the construction site activities of the Project. The ET shall make reference to the following information in conducting the inspection. During the inspection, the following information should be referred to:
(i) EIA Report and EM&A Manual recommendations on environmental protection and pollution control mitigation measures;
(ii) ongoing results of the EM&A programme;
(iii) works progress and programme;
(iv) individual works methodology proposals (which shall include the proposal on associated pollution control measures);
(v) contract specifications on environmental protection;
(vi) relevant environmental protection and pollution control legislations; and
(vii) previous site inspection results undertaken by the ET and others.
14.1.1.4 The Contractor shall keep the ER and ET Leader updated with all the relevant environmental related information on the construction contract necessary for him to carry out the site inspections. Site inspection results and associated recommendations for improvements to the environmental protection and pollution control efforts should be recorded and followed up by the Contractor in an agreed time-frame. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, and the deficiency and action reporting system formulated by the ET, to report on any remedial measures subsequent to the site inspections.
14.1.1.5 The ER, ET and the Contractor should also carry out ad-hoc site inspections if significant environmental problems are identified. Inspections may also be required subsequent to receipt of a valid environmental complaint, or as part of the investigation work, as specified in the Event and Action Plans for the EM&A programme.
14.2 Environmental Compliance
14.2.1.1 There are statutory requirements on environmental protection and pollution control requirements with which construction activities must comply.
14.2.1.2 In order to ensure the works comply with statutory requirements, all method statements of works should be submitted by the Contractor to the ER for approval and to the ET Leader for vetting to ensure sufficient environmental protection and pollution control measures have been included. EMIS is summarised in Appendix 4.1a. Any proposed changes to the mitigation measures shall be certified by the ET Leader and verified by the IEC as conforming to the relevant information and recommendations contained in the EIA Report.
14.2.1.3 The ER and ET shall also review the progress and programme of the works to check that relevant environmental legislation has not been violated, and that any foreseeable potential for violating laws can be prevented.
14.2.1.4 The Contractor should provide the update of the relevant documents to the ET Leader so that checking can be carried out. The document shall at least include the updated Works Progress Reports, updated Works Programme, method statements, any application letters for different licenses / permits under the environmental protection laws, and copies of all valid licenses / permits. The site diary and environmental records shall also be available for inspection by the relevant parties.
14.2.1.5 After reviewing the document, the ET shall advise the IEC and the Contractor of any non-compliance with legislative requirements on environmental protection and pollution control so that they can timely take follow-up actions as appropriate. If the follow-up actions still result in potential violation of environmental protection and pollution control requirements, the ER and ET should provide further advice to the Contractor to take remedial action to resolve the problem.
14.2.1.6 Upon receipt of the advice, the Contractor shall undertake immediate actions to correct the situation. The ER and ET shall follow up to ensure that appropriate action has been taken in order to satisfy legal requirements.
14.3 Choice of Construction Method
14.3.1.1 At times during the construction phase, the Contractor may submit method statements for various aspects of construction. This state of affairs would only apply to those construction methods that the EIA has not imposed conditions while for construction methods that have been assessed in the EIA, the Contractor is bound to follow the requirements and recommendations in the EIA study. The Contractor’s options for alternative construction methods may introduce adverse environmental impacts into the Project. It is the responsibility of the Contractor and ET, in accordance with established standards, guidelines and EIA study recommendations and requirements, to review and determine the adequacy of the environmental protection and pollution control measures in the Contractor’s proposal in order to ensure no unacceptable impacts would result. To achieve this end, the ET shall provide a copy of the Proactive Environmental Protection Proforma as shown in Appendix 14.1 to the IEC for approval before commencement of work. The IEC should audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts.
14.4.1.1 The following procedures should be undertaken upon receipt of any environmental complaint:
· The Contractor to log complaint and date of receipt onto the complaint database and inform the ER, ET and IEC immediately;
· The Contractor to investigate, with the ER and ET, the complaint to determine its validity, and assess whether the source of the problem is due to construction works of the Project with the support of additional monitoring frequency and stations, if necessary;
· The Contractor to identify remedial measures in consultation with the IEC, ET and ER if a complaint is valid and due to the construction works of the Project;
· The Contractor to implement the remedial measures as required by the ER and to agree with the ET and IEC any additional monitoring frequency and stations, where necessary, for checking the effectiveness of the remedial measures;
· The ER, ET and IEC to review the effectiveness of the Contractor's remedial measures and the updated situation;
· The ET/Contractor to undertake monitoring and audit to verify the situation if necessary, and oversee that circumstances leading to the complaint do not recur;
· If the complaint is referred by the EPD, the Contractor to prepare interim report on the status of the complaint investigation and follow-up actions stipulated above, including the details of the remedial measures and monitoring identified or already taken, for submission to EPD within the time frame assigned by the EPD; and
· The ET to record the details of the complaint, results of the investigation, subsequent actions taken to address the complaint and updated situation including the effectiveness of the remedial measures, supported by regular and monitoring results in the monthly EM&A reports.

[1] Daconil and Bayleton are two types of fungicides selected for the turf management. As shown in the calculation in the EIA report, the predicted concentration of Daconil in the water storage tanks is relatively much closer to the criteria, compared with Bayleton. So Daconil is selected as the more critical fungicide for monitoring. Similarly, Chlorpyrifos is selected as the more critical insecticide for monitoring.
