	Suspended Solids (SS)	0	5

ES.04. In the Reporting Month, a total of 9 Limit level water quality exceedances, namely 4 exceedances of turbidity and 5 exceedances of SS were recorded. According to the weather data from Observatory, there were successive rainstorms on 18 and 20 July 2023. Due to the impact of rain, the water quality of seasonal watercourse was inevitably affected by the sediment stirred up from the surrounding environment, even beyond the boundaries of the construction site. Weekly site inspection revealed that water quality mitigation measures were in place and the site conditions were generally in order. It was concluded that the exceedances were likely related to the impact of the Severe Tropical Storm and not caused by the work under the project.

ES.05. Monthly ecological monitoring for sensitive habitat for area of Contract 1 and Contract 2 were undertaken on 18^th July 2023. After analysing survey results in July from 2019 to 2023 for Contract 1, stable number of species richness and a significant increase in the abundance for Wetland and Non-wetland habitat are recorded in July 2023. This could be benefited by some positive factors such as the major construction works were completed and most of the PME has been removed from site. For Contract 2, after analysing survey results in July from 2019 to 2023, records in species richness and abundance for wetland and non-wetland habitats are unstable, this may due to natural fluctuation. According to the recent on-site observation, there are new built workshops by others situated on both sides of Lin Ma Hang Road so the disturbance to fauna species from construction works could be increased. Due to the cause was not related to this project, remedial action to remove or reduce source of disturbance is limited.

ES.06. Besides, compensation planting works have been conducted in early Jan 2023. Therefore, disturbance to fauna species from construction works have been largely minimised. In addition, woodland compensation and grassland reinstatement have been implemented in the second and third quarter of 2023. Hence, the habitat of fauna species would be gradually recovered and expectation of increase in the species richness and abundance for wetland habitat is high.

ES.07. In the Reporting Period, there was no vegetation clearance for both Contract 1 and Contract 2, and precautionary check for the presence of nesting birds was not required to carry out.

ES.08. Landscape and visual inspection at both Contracts were undertaken on 25^th July 2023. The Contractor was reminded to prevent the construction material pile within Tree Protection Zone and ensure no works is allowed within the TPZ.

ENVIRONMENTAL COMPLAINT

ES.09. No environmental complaint was recorded in this Reporting Month. The statistics of summons or successful prosecutions are summarized in the following tables.

Reporting Change

ES.012. No reporting change was made in the Reporting Month.

Site Inspection

ES.013. In the Reporting Month, joint site inspections for Contract 1 to evaluate the site environmental performance were carried out by the Resident Engineer, ET and the Contractor of the Contract 1 on 6^th, 13^th, 20^tt and 27^th July 2023. Moreover, joint site inspections for Contract 2 by the RE, ET and the Contractor of Contract 2 were carried out 6^th, 13^th, 20^tt and 27^th July 2023. No non-compliance was noted during the site inspections.

Future Key Issues

ES.014. During wet season, water quality mitigation measures as recommended in the EM&A Manual should be fully implemented, in particular to prevent surface runoff and other pollutants from flowing to local stream and Conservation Area.

ES.015. The Contractors are reminded to pay special attention on the air quality mitigation measures such as wheel wash facilities, watering of haul roads, loose soil construction surface and covering of dusty materials with tarpaulin sheet should be implemented as far as practicable.

ES.016. Construction noise would be a key environmental issue during construction phase of the Project. Noise mitigation measures such as using quiet plants and mobile noise barriers should be implemented in accordance with the EM&A requirement.

Water Quality Monitoring

3.5.11 Water quality parameters include dissolved oxygen, water temperature & depth, turbidity, salinity, pH and stream flow velocity shall be measured in-situ, and suspended solids shall be analyzed by a HOKLAS-accredited testing laboratory.

Dissolved Oxygen and Temperature Measurement

3.5.12 The dissolved oxygen (DO) measuring instruments should be portable and weatherproof. The equipment should also complete with cable and sensor, and DC power source. It should be capable of measuring:

• A DO level in the range of 0 ¡V 20 mg/L and 0 ¡V 200% saturation; and

• A temperature of 0 ¡V 45 degree Celsius.

3.5.13 The equipment should have a membrane electrode with automatic temperature compensation complete with a cable.

3.5.14 Should salinity compensation not be built-in to the DO equipment, in-situ salinity should be measured to calibrate the DO measuring instruments prior to each measurement.

Turbidity Measurement

3.5.15 The turbidity measuring instruments should be a portable and weatherproof with DC power source. It should have a photoelectric sensor capable of measuring turbidity level between 0¡V1000 NTU (for example, Hach model 2100Q or an approved similar instrument).

Salinity Measurement

3.5.16 A portable salinometer capable of measuring salinity in the range of 0¡V40 parts per thousand (ppt) should be provided for measuring salinity of the water at each monitoring location.

pH Measurement

3.5.17 A portable pH meter capable of measuring a range between 0.0 and 14.0 should be provided to measure pH under the specified conditions accordingly to the APHA Standard Methods.

Water Depth Measurement

3.5.18 A portable, battery-operated echo sounder or an approved similar instrument should be used for water depths determination at each designated monitoring station.

Stream Flow Velocity Equipment

3.5.19 Since the EM&A Manuals do not specified instrument to use stream flow velocity measurement, the monitoring of stream flow velocity is therefore proposed to be conducted by using a flow probe which is a digital water velocity meter.

Water Sampling Equipment

3.5.20 A water sampler is required for suspended solid (SS) monitoring. A water sampler e.g. Kahlsico Water Sampler, which is a transparent PVC cylinder with capacity not less than 2 litres, will be used for water sampling if water depth over than 0.5m.

3.5.21 For sampling from very shallow water depths e.g. <0.5 m, water sample will be collected from water surface below 100mm using plastic bottle to avoid inclusion of bottom sediment or humus. Moreover, Teflon/stainless steel bailer or self-made sampling buckets maybe used for water sampling. The equipment used for sampling will be depended the sampling location and depth situations.

Sample Containers and Storage

3.5.22 Water samples for suspended solid should be stored in high density polythene bottles with no preservative added, packed in ice (cooled to 4¢XC without being frozen) and delivered to the laboratory within 24 hours of collection and be analyzed as soon as possible after collection.

3.5.23 Analysis of suspended solids should be carried out in a HOKLAS or other accredited laboratory. Water samples of about 1L should be collected at the monitoring stations for carrying out the laboratory suspended solids determination. The SS determination work should start within 24 hours after collection of the water samples. The SS analyses should follow the APHA Standard Methods 2540D with Limit of Reporting of 2 mg/L.

3.7.2 The monitoring data recorded in the equipment e.g. 1-hour TSP meter, noise meter and Multi-parameter Water Quality Monitoring System are downloaded directly from the equipment at the end of each monitoring day. The downloaded monitoring data are input into a computerized database properly maintained by the ET. The laboratory results are input directly into the computerized database and QA/QC checked by personnel other than those who input the data. For monitoring activities require laboratory analysis, the local laboratory follows the QA/QC requirements as set out under the HOKLAS scheme for all laboratory testing.

3.8 Determination of Action/Limit (A/L) Levels

3.8.1 The baseline monitoring results form the basis for determining the environmental acceptance criteria for the impact monitoring. The air quality, construction noise and water quality criteria, namely Action and Limit levels were established according to Approved EM&A Manual, and they are listed in Tables 3-8, 3-9 and 3-10 below.

Date of Exceedance	Exceeded Location	Exceeded Parameter	Cause of Water Quality Exceedance
18 July 2023	M1, M2 & M4	Turbidity & Suspended Solids	According to the site information provided by the Contractor, there were no construction activities carried out on 18 July 2023 due to heavy rain. According to the weather data from Observatory, there were successive rainstorms on 18 and 20 July 2023. Due to the impact of rain, the water quality of seasonal watercourse was inevitably affected by the sediment stirred up from the surrounding environment, even beyond the boundaries of the construction site. Site inspection by ET was conducted on 20 July 2023 to audit the site environmental performance and implementation of mitigation measures. In view of the geographical location of Contract 2, M1 is located at upstream of Nam Hang Stream and outside site boundary of Contract 2, it acts as upstream of M2 and there was no works carried out near M1. There were no construction work conducted near M4 on Lin Ma Hang Road. Most of area on Sandy Ridge was hard paved and no adverse water quality impact was observed after rainy day. Contribution of polluted water to Nam Hang Road to M2 through seasonal channel was unlikely. In our investigation, there were no active work conducted near M1 and M4 and no adverse water quality impact observed at site areas during site inspection. In view of the current site condition, it was considered that all the exceedances were likely related to the impact of rainstorm and not caused by the work under the project.

7

7.1 Requirement

7.1.1 According to approved EIA report (AEIAR-198/2016), habitat types within project boundary comprise of watercourse, grassland, upland grassland, plantation, woodland and developed area. Natural habitats were of moderate ecological value in terms of species diversity, species rarity, species abundance, ecological linkage as well as nursery. Moreover, 0.3ha of wet woodland on the northern side of Sandy Ridge was deemed habitat with high ecological value. Four types of habitats were regarded as ecologically sensitive habitats, namely wet woodland, watercourses, upland grassland and woodland. Considering human disturbance in upcoming construction and operation phases, ecologically sensitive habitats shall be monitored in accordance with EM&A Manual.

7.1.2 The objective of ecologically sensitive habitats monitoring is to evaluate the effectiveness of measures to minimize impacts on concerned habitats from disturbance and pollution. In order to monitor the effectiveness of the measures to the minimize impact on ecologically sensitive habitats from disturbance and pollution, monthly monitoring during construction and operation phases is required as specified in EM&A Manual. Standard faunal transect and sampling surveys cover both wetland habitats (wet woodland and watercourse) and non-wetland habitats (upland grassland and woodland).

7.2 Methodology

7.2.1 Wetland habitats include wet woodland and watercourses. Monitoring surveys using standardized quantitative methodology will conduct at fixed points. For seasonal watercourse, the survey will be conducted whenever the habitat appears. Measures to respond to decreases in numbers of aquatic fauna using the wetland habitats and Action/Limit levels to trigger these measures are detailed in Table 7-1.

Table 7-1 Action and Limit Levels for Wet Woodland Habitats Monitoring

Action Level	Response	Limit Level	Response
Reduction in taxa diversity by 30%	Investigate cause and if cause identified as related to the project instigate remedial action to remove or reduce source of disturbance.	Reduction in taxa diversity by 50%	Investigate cause and if cause identified as related to the project instigate remedial action.

Remarks: Action and Limit Levels and Responses to Evidence of Declines in Aquatic Fauna

7.2.2 Non-wetland habitats consist of upland grassland and woodland. Monthly quantitative surveys of non-aquatic fauna will be conducted using standard route transect counts. Measures to respond to decreases in numbers of non-aquatic fauna using the non-wetland habitats and Action/Limit levels to trigger these measures are detailed in Table 7-2.

Table 7-2 Action and Limit Levels for Non-Wet Woodland Habitats Monitoring

Action Level	Response	Limit Level	Response
Reduction in species diversity by 30%	Investigate cause and if cause identified as related to the project instigate remedial action to remove or reduce source of disturbance.

Discussion

7.3.9 After analysing survey results in July from 2019 to 2023, stable number of species richness and a significant increase in the abundance for Wetland and Non-wetland habitat are recorded in July 2023. This could be benefited by some positive factors such as the major construction works were completed and most of the PME has been removed from site. Besides, compensation planting works have been conducted in early Jan 2023. Therefore, disturbance to fauna species from construction works have been largely minimised. In addition, woodland compensation and grassland reinstatement have been implemented in the second and third quarter of 2023. Hence, the habitat of fauna species would be gradually recovered and expectation of increase in the species richness and abundance for wetland habitat is high.

7.3.10 Yet, good site practice during construction, with reference to EM&A Manual, is still required to prevent or alleviate environmental impacts. Continuous monitoring is also recommended to inspect any changes in species diversity.

Discussion

7.4.9 After analysing survey results in July from 2019 to 2023, records in species richness and abundance for wetland and non-wetland habitats are unstable, this may due to natural fluctuation. According to the recent on-site observation, there are new built workshops by others situated on both sides of Lin Ma Hang Road so the disturbance to fauna species from construction works could be increased. Due to the cause was not related to this project, remedial action to remove or reduce source of disturbance is limited.

7.4.10 Nevertheless, the situation could be benefited by some positive factors such as the major construction works in this contract were completed and most of the PME has been removed from site. Besides, compensation planting works have been conducted in early Jan 2023. Therefore, disturbance to fauna species from construction works have been largely minimized internally. In addition, woodland compensation and grassland reinstatement have been implemented in the second and third quarter of 2023. Hence, the habitat of fauna species would be gradually recovered and expectation of increase in the species richness and abundance for wetland habitat is high.

7.4.11 Still, a good site practice during construction, with reference to EM&A Manual, is required to prevent or alleviate environmental impacts. For instance, the size of work areas should be minimized and disturbed areas should be reinstated immediately after completion of construction works. In addition, implementing proper waste disposal is necessary to reduce contamination to water and soil. Continuous monitoring is also recommended to inspect any significant decrease in species diversity.

7.4.12 The detailed Ecological Survey Reports for Contract 1 and Contract 2 are attached in Appendix K.

7.4.13 The tentative ecology inspection and monitoring in the next Reporting Month (August 2023) is scheduled on 22^nd August 2023.

7.5 Monitoring of Flora Species of Conservation Interest under Contract 1

7.5.1 According to the approved vegetation survey report and transplantation proposal under FEP-01/534/2017/A, an individual of flora species of conservation interest (the transplanted T-2928) was identified and transplanted to the receptor site.

7.5.2 According to approved vegetation survey report and transplantation proposal, post-transplantation monitoring was conducted once per week in the first three months after the transplantation in Oct 2018 and once in each of the following month in the remaining establishment period for 12 month. During the remaining construction phase of the project, the transplanted T-2928 would be monitored on quarterly basis.

7.5.3 A landscape sub-contractor was employed by the Contractor to monitor the health condition of transplanted species and provide advice on necessary weeding, fertilizing and pest control. The monitoring records were submitted to ET and IEC for review and record. Moreover, inspection of the transplanted T-2928 was undertaken by ET as part of the weekly site inspection. No construction activity and disturbance were observed at the location of the transplanted T-2928. The health condition of the transplanted T-2928 was fair with normal foliage color and density.

7.6 Measure for Protection of Nesting Bird

7.6.1 Pursuant to FEP-01/534/2017/A condition 2.19 and EP-534/2017/A condition 2.20, precautionary checks for the presence of nesting birds shall be carried out in the breeding season (February to July) before vegetation clearance.

7.6.2 In the Reporting Period, there was no vegetation clearance for both Contract 1 and Contract 2, and precautionary check for the presence of nesting birds was not required to carry out.

8. Landscape and Visual

8.1 Requirement

8.1.1 The EIA has recommended EM&A for landscape and visual resources to be undertaken during the design, construction and operational stages of the project. The design, implementation and maintenance of landscape mitigation measures is a key aspect of this and should be checked to ensure that they are fully realized and that potential conflicts between the proposed landscape measures and any other project works let its are resolved at the earliest possible date and without compromise to the intention of the mitigation measures. In addition, implementation of the mitigation measures recommended by the EIA will be monitored through the site audit programme.

8.1.2 A number of mitigation measures to ameliorate the landscape and visual impacts of the Project implementation is summarized in the EMIS of Appendix 13.1 of the EIA Report.

8.1.3 The landscape and visual mitigation measures proposed should be incorporated in the landscape and engineering design. Mitigation measures to be implemented during construction should be adopted from the start of construction and be in place throughout the entire construction period. Mitigation measures to be implemented during operation should be integrated into the detailed design and built as part of the construction works so that they are in place on commissioning of the Project. Tree transplantation and compensatory planting should be carried out as early as possible in the Project with transplantation carried out prior to construction starting in any particular area.

8.1.4 During construction phase, Landscape & Visual Monitoring of the contractor¡¦s operations should be conducted monthly and reported by ET, and countersigned by IEC.

13. Conclusions and Recommentations

13.1 Conclusions

13.1.1 This is the 60^th Monthly EM&A Report presenting the monitoring results and inspection findings for the period of 1^st to 31^st July 2023.

13.1.2 In the Reporting Month, no 24-hour or 1-hour TSP monitoring result that triggered the Action or Limit Levels was recorded. No NOEs or the associated corrective action was therefore required.

13.1.3 In the Reporting Month, no noise complaint (which triggered Action Level) was received and no Limit Level exceedance for noise monitoring exceedance was recorded.

13.1.4 In the Reporting Month, a total of 9 Limit level water quality exceedances, namely 4 exceedances of turbidity and 5 exceedances of SS were recorded. According to the weather data from Observatory, there were successive rainstorms on 18 and 20 Ju;y 2023. Due to the impact of rain, the water quality of seasonal watercourse was inevitably affected by the sediment stirred up from the surrounding environment, even beyond the boundaries of the construction site. Weekly site inspection revealed that water quality mitigation measures were in place and the site conditions were generally in order. It was concluded that the exceedances were likely related to the impact of the Severe Tropical Storm and not caused by the work under the project.

13.1.5 Monthly ecological monitoring for sensitive habitat for area of Contract 1 and Contract 2 were undertaken on 18^th July 2023. After analysing survey results in July from 2019 to 2023 for Contract 1, stable number of species richness and a significant increase in the abundance for Wetland and Non-wetland habitat are recorded in July 2023. This could be benefited by some positive factors such as the major construction works were completed and most of the PME has been removed from site. For Contract 2, after analysing survey results in July from 2019 to 2023, records in species richness and abundance for wetland and non-wetland habitats are unstable, this may due to natural fluctuation. According to the recent on-site observation, there are new built workshops by others situated on both sides of Lin Ma Hang Road so the disturbance to fauna species from construction works could be increased. Due to the cause was not related to this project, remedial action to remove or reduce source of disturbance is limited.

13.1.6 Besides, compensation planting works have been conducted in early Jan 2023. Therefore, disturbance to fauna species from construction works have been largely minimised. In addition, woodland compensation and grassland reinstatement have been implemented in the second and third quarter of 2023. Hence, the habitat of fauna species would be gradually recovered and expectation of increase in the species richness and abundance for wetland habitat is high.

13.1.7 In the Reporting Period, there was no vegetation clearance for both Contract 1 and Contract 2, and precautionary check for the presence of nesting birds was not required to carry out.

13.1.8 Landscape and visual inspection at both Contracts were undertaken on 25^th July 2023. The Contractor was reminded to prevent the construction material pile within Tree Protection Zone and ensure no works is allowed within the TPZ.

13.1.9 In the Reporting Month, no environmental complaints, summons and prosecution were received. In addition, no complaints received and emergency events relating to violation of environmental legislation for illegal dumping and landfilling were received.

13.1.10 In the Reporting Month, joint site inspections for Contract 1 to evaluate the site environmental performance were carried out by the Resident Engineer, ET and the Contractor of the Contract 1 on 6^th, 13^th, 20^tt and 27^th July 2023. Moreover, joint site inspections for Contract 2 by the RE, ET and the Contractor of Contract 2 were carried out on 6^th, 13^th, 20^tt and 27^th July 2023. No non-compliance was noted during the site inspections.

13.2 Recommendations

13.2.1 During wet season, water quality mitigation measures as recommended in the EM&A Manual should be fully implemented, in particular to prevent surface runoff and other pollutants from flowing to local stream and Conservation Area.

13.2.2 The Contractors are reminded to pay special attention on the air quality mitigation measures such as wheel wash facilities, watering of haul roads, loose soil construction surface and covering of dusty materials with tarpaulin sheet should be implemented as far as practicable.

13.2.3 Construction noise would be a key environmental issue during construction phase of the Project. Noise mitigation measures such as using quiet plants and mobile noise barriers should be implemented in accordance with the EM&A requirement.
