Impact Monitoring Methodology

2.6.        Integrated sound level meter will be used for the noise monitoring. The meter will be in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications. Immediately prior to and following each noise measurement the accuracy of the sound level meter will be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements will be accepted as valid only if the calibration levels before and after the noise measurements agree to within 1.0 dB(A).

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

 

Action and Limit Levels

2.8.        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.

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

 

2.9.        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.

 

Monitoring Results and Observations

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

3.           WATER QUALITY

 

3.1.        In accordance with the recommendations of the EIA, water quality monitoring is required during dredging for the submarine pipelines and, during operation phase. 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.

3.2.        The water quality monitoring programme was be carried out to allow any deteriorating water quality to be readily detected and timely action taken to rectify the situation.

3.3.        Water quality monitoring for the Contract can be divided into the following stages:

-              Dredging activities during construction phase;

-              Discharge of effluent from main disinfection during construction phase; and

-              Operation activities during commissioning phase

Water Quality Parameters

3.4.        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 to be measured in the impact monitoring are listed in Table 3.1.

3.5.        In addition to the water quality parameters, other relevant data were also being measured and recorded in Water Quality Monitoring Logs, including the location of the sampling stations, water depth, time, weather conditions, sea conditions, tidal stage, current direction and velocity, special phenomena and work activities undertaken around the monitoring and works area that may influence the monitoring results.

Monitoring Equipment

3.6.        For water quality monitoring, the following equipment were used:

Dissolved Oxygen and Temperature Measuring Equipment - The instrument was a portable, weatherproof dissolved oxygen measuring instrument complete with cable, sensor, comprehensive operation manuals, and was operable from a DC power source. It was capable of measuring: dissolved oxygen levels in the range of 0 - 20 mg/L and 0 - 200% saturation; and a temperature of 0 - 45 degrees Celsius. It has a membrane electrode with automatic temperature compensation complete with a cable of not less than 35 m in length. Sufficient stocks of spare electrodes and cables were available for replacement where necessary (e.g. YSI model 59 DO meter, YSI 5739 probe, YSI 5795A submersible stirrer with reel and cable or an approved similar instrument).

Turbidity Measurement Equipment - The instrument was a portable, weatherproof turbidity-measuring unit complete with cable, sensor and comprehensive operation manuals. The equipment was operated from a DC power source, it has a photoelectric sensor capable of measuring turbidity between 0 - 1000 NTU and complete with a cable with at least 35 m in length (for example Hach 2100P or an approved similar instrument).

Salinity Measurement Instrument - A portable salinometer capable of measuring salinity in the range of 0 - 40 ppt was provided for measuring salinity of the water at each monitoring location.

Water Depth Gauge - A portable, battery-operated echo sounder (for example Seafarer 700 or a similar approved instrument) was used for the determination of water depth at each designated monitoring station. This unit will preferably be affixed to the bottom of the work boat if the same vessel is to be used throughout the monitoring programme. The echo sounder was suitably calibrated.

Positioning Device - A Global Positioning System (GPS) was used during monitoring to allow accurate recording of the position of the monitoring vessel before taking measurements. The Differential GPS, or equivalent instrument, was suitably calibrated at appropriate checkpoint (e.g. Quarry Bay Survey Nail) to verify that the monitoring station is at the correct position before the water quality monitoring commence.

Water Sampling Equipment - A water sampler, consisting of a PVC or glass cylinder of not less than two litres, which can be effectively sealed with cups at both ends, was used. The water sampler has a positive latching system to keep it open and prevent premature closure until released by a messenger when the sampler is at the selected water depth.

Total Residual Chlorine -Total residual chlorine (TRC) shall be measured in-situ using approved test kit.

Sampling / Testing Protocols

3.7.        All in situ monitoring instruments were checked, calibrated, and certified by a laboratory accredited under HOKLAS or any other international accreditation scheme before use, and subsequently re-calibrated at monthly intervals throughout the stages of the water

quality monitoring. Responses of sensors and electrodes were checked with certified standard solutions before each use.

3.8.        On-site calibration of field equipment was following the “Guide to On-Site Test Methods for the Analysis of Waters”, BS 1427: 2009. Sufficient stocks of spare parts were maintained for replacements when necessary. Backup monitoring equipment was made available so that monitoring can proceed uninterrupted even when equipment is under maintenance, calibration etc.

Laboratory Measurement and Analysis

3.9.        Sufficient volume of each water sample was collected for carrying out the laboratory analyses. Using chain of custody forms, collected water samples were transferred to a HOKLAS accredited laboratory (Acumen Laboratory and Testing Limit - HOKLAS 241) for immediate processing. The determination work was start within the next working day after collection of the water samples. Analytical methodology and sample preservation of other parameters were based on the latest edition of Standard Methods for the Examination of Waste and Wastewater published by APHA, AWWA and WPCF and methods by USEPA, or suitable method in accordance with requirements of HOKLAS or another internationally accredited scheme. The QA/QC details were in accordance with the requirements of HOKLAS or another internationally accredited scheme.

3.14.         Effluent of disinfection from desalination plant shall be collected at a suitable location after all treatment process before discharge. The sampling location should be agreed with WSD and EPD, and should fulfil the following requirements:

-              Effluent collected at the sampling location is representative to the effluent discharged at the outfall diffuser.

-              Sampling works at the sampling location would not interfere with the desalination plant operation.

-              Sampling works at the sampling location would not induce safety hazard (e.g. staff sampling effluent drops into the culvert)

 

3.15.         According to the approved Flushing and Disinfection Procedure and Supplementary of the Disinfection Procedure for Desalination Plant at Tseung Kwan O, the sampling point of the dechlorinated effluent was located at Contact tank/Product Water Tank (PWT) and T1GKC01AA502/manhole 18. The approved sampling location was shown in Table 3.4, Figure 3.2 and Figure 3.3 below.

Sampling Frequency

Commissioning Phase

3.16.    Impact water quality monitoring were carried out three days per week during the commissioning phase. Monitoring at each station was undertaken once per day. The interval between two sets of monitoring was not less than 36 hours. The monitoring frequency would be increased in the case of exceedances of Action/Limit Levels if considered necessary by ET. Monitoring frequency would be maintained as far as practicable.

Disinfection

3.17.    For the discharge of dechlorinated effluent used after main sterilization, in-situ testing of total residual chlorine should be conducted every 1 hour (not less than) at the discharge point(s) when dechlorinated effluent is being discharged.

Sampling Depths & Replication

3.18.    During impact water quality monitoring, each station was sampled, and measurements/ water samples were taken at three depths, 1 m below the sea surface, mid-depth, and 1 m above the seabed. For in situ measurements, duplicate readings were made at each water depth at each station. Duplicate water samples were collected at each water depth at each station.

Action and Limit Levels

Commissioning Phase

3.19.    The Action and Limit Levels have been set based on the derivation criteria specified in the EM&A Manual. The Action/Limit Levels have been derived and are presented in Table 3.6.

Disinfection

3.20.    The Action and Limit Levels have been set in accordance with the approved EM&A Manual and presented in Table 3.6. For the TRC, the discharge should be suspended if the TRC level of the dechlorinated effluent exceeds the 0.1 mg/L. Chlorinated water should be fully neutralized before discharge. Discharge of the water will be done once it is ensured that the chlorine has been neutralized and it is below the discharge limit.

iv. Monitoring of Total Residual Chlorine will be conducted when cleaning and sterilization of the new freshwater main is carried out.

Monitoring Results and Observations

Construction Phase

3.21.    Referring to EM&A Manual, the general water quality monitoring should be carried out when there are marine-related construction activities undertaken. General water quality monitoring at the ten monitoring stations (CE, CF, WSR1, WSR2, WSR3, WSR4, WSR16, WSR33, WSR36 and WSR37) was ceased from 1 September 2023 due to the completion of marine-related construction works.

Commissioning Phase

3.22.    Considering the first testing and commissioning(T&C) phase of Tseung Kwan O Desalination Plant was started in the reporting period, additional marine water quality monitoring was conducted at the thirteen monitoring stations (CE, CF, WSR1, WSR2, WSR3, WSR4, WSR16, WSR33, WSR36, WSR37, NF1, NF2 and NF3) from 12 December

2023. The Action and Limit Level would be referred to the approved EM&A Manual Table

5.4 First-year Operation Phase Marine Water Monitoring

3.23.    Thirty-five (35) of the commissioning phase water quality monitoring results of SS obtained had exceeded the Action Level. Twenty-seven (27) of the commissioning phase water quality monitoring results of SS obtained during the reporting period had exceeded the Limit Level.

3.24.    Investigation on the reason of exceedance has been carried out, where the exceedances of SS on 12, 14, 16, 19, 21, 23, 26 and 28 December 2023 were concluded to be unrelated to the Contract as detailed in the Incident Reports on Action Level or Limit Level Non- compliance along with supporting materials in Appendix K.

3.25.    Monitoring results of 8 key parameters: Salinity, DO, turbidity, SS, pH, temperature, Total Residual Chlorine and Iron in this reporting, are summarized in Table 3.7, and detailed results are presented in Appendix G.

5.           LANDFILL GAS MONITORING

 

Monitoring Requirement

5.1.        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.

Monitoring Programme

5.2.        Since part of the desalination plant (Wan Po Road and MIC compound/Basketball Court) and the indicative area of natural slope mitigation works fall within the SENT Landfill Extension Consultation Zone in this contract (Figure 5.1), landfill gas monitoring would be required for Wan Po Road and MIC compound/Basketball Court (Figure 5.2) if excavations were conducted at more than 300mm deep. Although SENT Landfill Extension has commenced operation since November 2021, no excavation works were conducted at MIC compound/Basketball Court. Hence no landfill gas monitoring would be scheduled for MIC compound/Basketball Court at the current stage.

Monitoring Location

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

5.4.        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.

 

5.5.        For excavations between 300mm and 1m deep, measurements were carried out:

 

-     Directly after the excavation has been completed; and

-     Periodically whilst the excavation remains open.

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

1)                   Control station value already exceed either the Action or Limit Level.

2)                   No silt plume or pollution discharge from site area was observed.

3)                   Rainfall was recorded at Tseung Kwan O during the monitoring period, rainfall may lead to release of SS content form the soil of the nearby lands (e.g., Country Park, fill bank).

4)                   No action and limit level exceedance observed at WSR37 (Outfall Shaft).

5)                   Marine construction activity was completed.

6)                   No operation activities related to the release of SS in the reporting period.

7)                   Water quality mitigation measures were observed maintained / implemented properly (double silt curtain).

Conclusion:

During water quality monitoring on 12 December 2023 and 14 December 2023, four (4) Action Level exceedances and three (3) Limit Level exceedance were recorded during mid-ebb tide, and two (2) Action Level and one (1) Limit Level exceedances of Suspended Solids were recorded during mid-flood tide. Total six (6) Action Level and four (4) Limit Level exceedances for SS of impact water quality monitoring were recorded between 1 December to 15 December 2023.

The marine construction works were completed on 1 September 2023. The operation activities were shown in the table below.

According to the record, most of the operation activities were instrument checking and adjustment, no operation activities might lead to the release of SS during the reporting period. After investigation, all exceedances were considered non-project related.

Operation Activities:

12 December 2023

14 December 2023

-          Production of desalinated water

-          Goods receiving at the plant

-          Instrumentation and Control Instrument checking

-          Instrument adjustment at Dissolved Air Flotation and Filtration (ActiDAFF)

-          Production of desalinated water

-          CCT and product water sampling and analysis

-          Instrumentation and Control Instrument checking and maintenance

1)                   Control station value already exceed either the Action or Limit Level.

2)                   No silt plume or pollution discharge from site area was observed.

3)                   Rainfall was recorded at Tseung Kwan O during the monitoring period, rainfall may lead to release of SS content form the soil of the nearby lands (e.g., Country Park, fill bank).

4)                   No action and limit level exceedance observed at WSR37 (Outfall Shaft).

5)                   Marine construction activity was completed.

6)                   No operation activities related to the release of SS in the reporting period.

7)                   Water quality mitigation measures were observed maintained / implemented properly (double silt curtain).

Conclusion:

During water quality monitoring on 16 December 2023, 19 December 2023, 21 December 2023, 23 December 2023, 26 December 2023 and 30 December 2023, twenty-eight (28) Action Level exceedances and twenty-two (22) Limit Level exceedance were recorded during mid-flood tide, and one (1) Action Level and one (1) Limit Level exceedances of Suspended Solids were recorded during mid-ebb tide. Total twenty-nine (29) Action Level and twenty-three (23) Limit Level exceedances for Suspended Solid of impact water quality monitoring were recorded between 16 December to 31 December 2023.

Marine construction works were completed since 1 September 2023.

The operation activities in the reporting period were shown in the table below. The no discharge of SS during the backwashing of Dissolved Air Flotation and Filtration (ActiDAFF). The major activities of the plant operation might not lead to the release of SS during the reporting period.

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