A summary of implementation status of the environmental mitigation measures for the construction phase of the Project during the reporting period is provided in Appendix C.

2. NOISE

2.1. MONITORING REQUIREMENTS

To ensure no adverse noise impact, construction noise monitoring is recommended to be carried out within 300m radius from the nearby noise sensitive receivers (NSRs), during construction phase. The NSRs selected as monitoring station are (i) NSR4 - Creative Secondary School, (ii) NSR24 - PLK Laws Foundation College, and (iii) NSR31 - School of Continuing and Professional Studies - CUHK respectively.

No impact construction noise monitoring was conducted in the reporting period due to the overly distant monitoring station from the works location, where they were farther than 1 km from the closet monitoring station NSR4 to the works location.

2.2. MONITORING PARAMETERS, FREQUENCY AND DURATION

Construction noise level would be measured in terms of the A-weighted equivalent continuous sound pressure level (LAeq). Leq 30min was used as the monitoring parameter for the time period between 0700 and 1900 on normal weekdays. Table 2.1 summarizes the monitoring parameters, frequency and duration of the impact noise monitoring.

Table 2.1 Noise Monitoring Parameters, Time, Frequency and Duration

Time	Duration	Interval	Parameters
Daytime: 0700-1900	Day time: 0700-1900 (during normal weekdays)	Continuously in Leq 5min/Leq 30min (average of 6 consecutive Leq 5min)	Leq 30min L10 30min & L90 30min

2.3. MONITORING LOCATIONS

The monitoring locations should normally be made at a point 1m from the exterior of the NSRs building façade and be at a position 1.2m above the ground. A correction of +3dB(A) should be made to the free-field measurements.

According to the environmental findings detailed in the EIA report and Baseline Monitoring Report, the designated locations for the construction noise monitoring are listed in Table 2.2 below.

Table 2.2 Noise Sensitive Receivers

NSR ID	Noise Sensitive Receivers	Monitoring Location	Position
NSR 4	Creative Secondary School	Roof Floor	1 m from facade
NSR 24	PLK Laws Foundation College	Pedestrian Road on Ground Floor	Free-field
NSR 31	School of Continuing and Professional Studies - CUHK	Roof Floor	1 m from facade

The monitoring locations should normally be made at a point 1m from the exterior of the NSRs building façade and be at a position 1.2m above the ground. A correction of +3dB(A) should be made to the free-field measurements. Three noise monitoring locations for impact monitoring at the nearby sensitive receivers are shown in Figure 2.1-2.3.

2.4. ACTION AND LIMIT LEVELS

The Action/Limit Levels are in line with the criteria of Practice Note for Professional Persons (ProPECC PN 2/93) ¡§Noise from Construction Activities - Non-statutory Controls¡¨ and Technical Memorandum on Environmental Impact Assessment Process issued by HKSAR Environmental Protection Department [¡§EPD¡¨] under the Environmental Impact Assessment Ordinance, Cap 499,

S.16 are presented in Table 2.3.

Table 2.3 Action and Limit Levels for Construction Noise Monitoring per EM&A Manual

Time Period	Action Level	Limit Level (dB(A))
0700-1900 on normal weekdays	When one documented complaint is received from any one of the noise sensitive receivers	- 70 dB(A) for school and - 65 dB(A) during examination period

Notes: Limits specified in the GW-TM and IND-TM for construction and operation noise, respectively.

If exceedances were found during noise monitoring, the actions in accordance with the Event and Action Plan shall be carried out according to Appendix E.

2.5. MONITORING RESULTS AND OBSERVATIONS

Referring to EM&A manual Section 4.1.2, the impact noise monitoring should be carried out when there are project-related construction activities undertaken within a radius of 300m from the monitoring stations. No noise monitoring station was located within a radius of 300m of the Project site as shown in Figure 2.4, no impact monitoring for noise impact was conducted in the reporting period.

Figure 2.4 Site Layout Plan with Noise Sensitive Receivers and Desalination Plant

3. WATER QUALITY

In accordance with the recommendations of the EIA, water quality monitoring is required during dredging for the submarine pipelines and, during operation phase. In addition, baseline water quality monitoring was conducted prior to the commencement of marine construction activities.

The following Section provides details of the water quality monitoring to be undertaken by the Environmental Team (ET) to verify the distance of sediment and brine plume dispersion and to identify whether the potential exists for any indirect impacts to occur to ecological sensitive receivers. The water quality monitoring programme was carried out to allow any deteriorating water quality to be readily detected and timely action taken to rectify the situation.

Water quality monitoring for the Project can be divided into the following stages:

- Dredging activities during construction phase;

- Discharge of effluent from main disinfection during construction phase;

- Operation phase - first year upon commissioning; and,

- Continuous monitoring of effluent quality.

In addition, the marine works contractor is required to complete a silt curtain efficiency test for the combined use of floating silt curtain type and cage type silt curtain for dredging at seawater intake to confirm the silt curtain reduction efficiency assumptions of the assessment. The details of testing plan together with the silt curtain deployment plan shall be submitted by the ET to seek approval from the IEC and EPD.

With the onset of marine dredging activities in late April at Outfall Shaft Area, a silt curtain efficiency test has been conducted at the Outfall Shaft Area on 16t April 2021 at 6 monitoring intervals (08:00, 10:00, 12:00, 14:00, 16:00, 18:00). The baseline monitoring event has been conducted on 10 April 2021 at 5 monitoring locations. Testing protocols and methodologies had followed the guidelines as presented in the EM&A Manual Annex C. Detailed analysis of in-situ and laboratory data was presented in a separate report which has been submitted to EPD after approval by IEC on 31 May 2021. The overall Silt Removal Effectiveness at Outfall Shaft Area for the combined used of cage and floating type silt curtains was 95.28%.

3.1. WATER QUALITY PARAMETERS

The parameters that have been selected for measurement in situ and in the laboratory are those that were either determined in the EIA to be those with the most potential to be affected by the construction works or are a standard check on water quality conditions. Parameters measured in the impact monitoring are listed in Table 3.1.

ii. Measurement data of Suspending Solids would be rounding to 2.5mg/L if the value was less than 2.5mg/L to facilitate data analysing.

4. WASTE

The waste generated from this Project includes inert construction and demolition (C&D) materials, and non-inert C&D materials. Non- inert C&D materials are made up of general refuse, vegetative wastes and recyclable wastes such as plastics and paper/cardboard packaging waste. Steel materials generated from the project are also grouped into non-inert C&D materials as the materials were not disposed of with other inert C&D materials. With reference to relevant handling records and trip tickets of this Project, the quantities of different types of waste generated in the reporting period are summarized in Table 4.1. Details of cumulative waste management data are presented as a waste flow table in Appendix G.

5. LANDFILL GAS MONITORING

5.1. MONITORING REQUIREMENT

In accordance with Section 11 of the EM&A Manual, monitoring of landfill gas is required for construction works within the 250m Consultation Zone. Part of the desalination plant and the indicative area of natural slope mitigation works fall within the SENT Landfill Extension Consultation Zone; and part of the 1,200 mm diameter fresh water mains along Wan Po Road falls within the SENT Landfill and SENT Landfill Extension Consultation Zones, TKO Stage II/III Restored Landfill and TKO Stage I Restored Landfill Consultation Zones.

5.2. MONITORING LOCATION

Monitoring of oxygen, methane, carbon dioxide and barometric pressure was performed for excavations at 1m depth or more within the consultation Zone.

During construction of works within the consultation zones, excavations of 1m depth or more was monitored:

- 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 through the working day whilst workers are in the excavation.

For excavations between 300mm and 1m deep, measurements should be carried out:

- Directly after the excavation has been completed; and

- Periodically whilst the excavation remains open.

5.3. MONITORING PARAMETERS

LFG monitoring was carried out to identify any migration between the landfill and the Project and to ensure the safety of the construction, operation and maintenance personnel working on-site, visitors and any other person within the Project area.

The following parameters were monitored:

- Methane.

- Oxygen.

- Carbon Dioxide.

- Barometric Pressure.

5.4. MONITORING LOCATION

The area required to be monitored for landfill gas in the reporting period is shown in Figure 5.1.

Figure 5.1 Overview of the SENT Extension Consultation Zone and the Project Site Area

5.5. ACTION AND LIMIT LEVEL

Action and Limit Level are provided in Table 5.1.

Table 5.1 Action and Limit Level for Landfill Gas Monitoring

Parameters	Action Level	Limit Level
Oxygen (O2)	<19% O2	<19% O2
Methane (CH4)	>10% LEL	>20% LEL
Carbon Dioxide (CO2)	>0.5% CO2	>1.5% CO2

5.6. MONITORING EQUIPMENT

The monitoring equipment used in the reporting period could be referring to Section 5.6 of the Monthly EM&A Report.

Figure 5.1 Location Map for Landfill Gas Monitoring at Wan Po Road

In this reporting period, 66 times of landfill gas monitoring were recorded at Wan Po Road (Ch1+625 - Ch1+513). No exceedance of action and limit levels for methane, oxygen and carbon dioxide was observed. Monitoring was conducted during excavations at 1m depth or more within the consultation zone and whenever workers entered the excavation on the day.

6. SUMMARY OF MONITORING EXCEEDANCE, COMPLAINTS, NOTIFICATION OF SUMMONS AND PROSECUTIONS

The Environmental Complaint Handling Procedure is shown in below Figure 6.1:

Figure 6.1 Environmental Complaint Handling Procedures

No noise monitoring was conducted during the reporting period since there are no Contract-related construction activities undertaken within a radius of 300m from the monitoring locations. No Action Level exceedance was recorded during the reporting period.

The EM&A works for water quality were conducted during the reporting period in accordance with the EM&A Manual.

During the impact monitoring period between December 2021 to February 2022, one hundred and ninety-three (193) of the general water quality monitoring results of SS obtained had exceeded the Action Level. One hundred and thirty-two (132) of the general water quality monitoring results of SS obtained during the reporting quarter had exceeded the Limit Level.

After investigation, all exceedances were considered non-project related.

In this reporting period, 66 times of landfill gas monitoring were recorded at Wan Po Road (Ch1+625 - Ch1+513). No exceedance of action and limit levels for methane, oxygen and carbon dioxide was observed. Monitoring was conducted during excavations at 1m depth or more within the consultation zone and whenever workers entered the excavation on the day.

ACJCJ¡¦s Environmental Office received a text message on 14 January 2022 from EPD inspector claiming that susceptible oil spillage at the water surface nearby to Outfall Shaft was observed during their routine drone check on 13 January 2022. The message from EPD was relayed to ET by AJCJV on 15 January 2022. Immediate investigation by AJCJV has been made after the acknowledgement of the incident, whilst implementing emergency clean up measure on any residue oil spillage. After investigation, the oil spillage was unlikely originated from the Outfall Shaft. The incident may therefore be considered as non-project related. Detail of the incident could be referring to Monthly EM&A Report Appendix O.

Moreover, oil stains were also observed at CEDD pier after leaving of Explosives Vessel on 28 January, 9 and 23 February 2022 by Supervising Officer¡¦s Representative (SOR) during site inspection. ET will keep closely monitoring the performance of Contractor, implementation of water quality mitigation measure and other contamination issue around the Project site, to ensure the EM&A requirement is properly implemented.

No notification of summons and prosecution was received in the reporting period. Statistics on complaints and regulatory compliance are summarized in Appendix H.

7. EM&A SITE INSPECTION

Site inspections were carried out on a weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures under the Contract.

Joint site inspections were also carried out by ET and IEC on 7, 15, 22 and 31 December 2021, 4, 11, 18, 26 and 31 January 2022, 8, 17, 23 and 28 February 2022.

Minor deficiencies were observed during weekly site inspection. Key observations during the site inspections are summarized below:

- Storage of chemicals and construction materials on-site was not conducted properly

- Housekeeping of drainage channel

- Underground seepage marine water was not by-pass through an uncontaminated isolation system.

The Contractor has rectified the observations identified during environmental site inspections in the reporting period.

According to the EIA Study Report, Environmental Permit, contract documents and EM&A Manual, the mitigation measures detailed in the documents should be implemented as much as practical during the reporting period. An updated Implementation Status of Environmental Mitigation Measures (EMIS) is provided in Appendix C.

8. CONCLUSIONS AND RECOMMENDATIONS

This is the 8th Quarterly EM&A Report for the Project which summarizes the key findings of the EM&A programme during the reporting period from 1 December 2021 to 28 February 2022, in accordance with the EM&A Manual and the requirement under FEP-01/503/2015/A.

No noise monitoring was conducted in the reporting period due to the over distant monitoring station from the works location.

During the impact monitoring period between December 2021 to February 2022, one hundred and ninety-three (193) of the general water quality monitoring results of SS obtained had exceeded the Action Level. One hundred and thirty-two (132) of the general water quality monitoring results of SS obtained during the reporting quarter had exceeded the Limit Level.

After investigation, all exceedances were considered non-project related.

In this reporting period, 66 times of landfill gas monitoring were recorded at Wan Po Road (Ch1+625 - Ch1+513). No exceedance of action and limit levels for methane, oxygen and carbon dioxide was observed. Monitoring was conducted during excavations at 1m depth or more within the consultation zone and whenever workers entered the excavation on the day.

ACJCJ¡¦s Environmental Office received a text message on 14 January 2022 from EPD inspector claiming that susceptible oil spillage at the water surface nearby to Outfall Shaft was observed during their routine drone check on 13 January 2022. The message from EPD was relayed to ET by AJCJV on 15 January 2022. Immediate investigation by AJCJV has been made after the acknowledgement of the incident, whilst implementing emergency clean up measure on any residue oil spillage. After investigation, the oil spillage was unlikely originated from the Outfall Shaft. The incident may therefore be considered as non-project related. Detail of the incident could be referring to Monthly EM&A Report Appendix O.

Moreover, oil stains were also observed at CEDD pier after leaving of Explosives Vessel on 28 January, 9 and 23 February 2022 by Supervising Officer¡¦s Representative (SOR) during site inspection. ET will keep closely monitoring the performance of Contractor, implementation of water quality mitigation measure and other contamination issue around the Project site, to ensure the EM&A requirement is properly implemented.

Weekly environmental site inspection was conducted during the reporting period. Minor deficiency was observed during site inspection and was rectified. The environmental performance of the project was therefore considered satisfactory.

According to the environmental site inspections performed in the reporting period, the Contractor is reminded to pay attention on maintaining proper materials storage.

No environmental complaint was received in the reporting period.

No notification of summons or prosecution was received since commencement of the Contract.

The ET will keep track on the construction works to confirm compliance of environmental requirements and the proper implementation of all necessary mitigation measures.
