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

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.

Manual Disinfection
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 3.5. 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.

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 L.
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 3.6, and detailed results are presented in Appendix G.

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

The Contractor should make the workers are aware of potential hazards of working in confined spaces (any chamber, manhole or culvert which is large enough to permit access to personnel). Such work in confined spaces is controlled by the Factories and Industrial Undertakings (Confined Spaces) Regulations of the Factories and Industrial Undertakings Ordinance. Following the Safety Guide to Working in Confined Spaces ensures compliance with the above regulations. |

Where below ground service entries are necessary to the Incoming Switchgear Room, 132 kV Substation and Chlorine Store (I) and (II), the entry point should be sealed to prevent gas entry. In addition, any below grade cable trenches entering the Incoming Switchgear Room and 132 kV Substation can become the pathway for landfill gas and hence grilled metal covers should be used. |

It is recommended regular landfill gas monitoring should be carried out at the Incoming Switchgear Room, 132 kV Substation and Chlorine Store (I) and (II). The monitoring frequency will be monthly for the first year of operation. If the monitoring results show no sign of landfill gas migration, reduce the monitoring frequency to once every six months. |

The manholes and utility pits within the Project Site and along the fresh water mains. Each manhole/ utility pit should be monitored with two measurements (at mid depth and base). Each measurement should be monitored for a minimum of 10 minutes. A steady reading and peak reading should be recorded at each manhole/ utility pit and for each measurement. The need for venting the manhole/ utility pit and further monitoring will be reviewed after the initial monitoring. |

INTRODUCTION
Background
1.1. The Project,
Design, Build and Operate First Stage of Tseung Kwan O Desalination Plant (TKODP), is a Designated Project under the Environmental Impact
Assessment Ordinance (Cap. 499) (EIAO) and is
currently governed by a Further Environmental Permit (EP No. FEP - 01/503/2015/A) for the
pre-operation and operation of the Project.
1.2. The Jardine Engineering Corporation, Limited, China State Construction
Engineering (Hong Kong) Limited and Acciona Agua, S.A. Trading As AJC Joint Venture (AJCJV) is contracted to carry out the
Design, Build and Operate First Stage of Tseung Kwan O Desalination Plant (DPTKO) under
Contract No. 13/WSD/17 (the Project).
1.3. Acuity Sustainability Consulting Limited (ASCL)
is commissioned by AJCJV to undertake the
Environmental Team (ET) services as required and/or implied, both explicitly
and implicitly, in
the Environmental Permit (EP), Environmental Impact Assessment Report (EIA Report) (Register No.
AEIAR-192/2015) and Environmental Monitoring and Audit Manual (EM&A Manual) for the
Project; and to carry out the Environmental Monitoring and Audit (EM&A) programme
in fulfillment of the EIA Report’s EM&A requirements and Contract No. 13/WSD/17
Specification requirements.
1.4. The proposed Desalination Plant at Tseung Kwan O (DPTKO)
will produce potable water with an initial capacity of 135 million litres per day
(MLD), expandable to an ultimate capacity of 270 MLD in the future
to provide a secure and alternative fresh water resource complying with the World Health
Organization (WHO) standards. The plant will adopt the Seawater Reverse Osmosis (SWRO) technology, which
dominates the market due to its reliability and progressive reduction in cost as the
technology advances.
1.5. A baseline coral survey was conducted in 13 October 2023 to verify the
validity of the pervious EIA findings as well as to provide
updated coral data for impact
monitoring during the pre-operation and
operational phases. Two indirect impact sites and one control site were identified during the
baseline coral survey for impact monitoring.
2
Methodology
2.1.
All tagged coral colonies in C2, C3 and
C8 will be monitored monthly till the end of the first year of the plant
operation. The monitoring team will record
the following parameters (using the same methodology adopted during the
pre-construction phase survey): size, presence, survival, health conditions (percentage of mortality) and percentage of sediment
of each tagged coral
colonies. The general environmental conditions during the survey date will also be monitored.
2.2
Photographic records of the tagged
coral colonies will be taken as far as possible maintaining the same aspect and orientation as photographs taken for the pre-translocation
surveys. All the tags for marking coral colonies
will be removed / retrieved once the monitoring programme is completed.
2.3
The results of the pre-operation phase
monitoring surveys should be reviewed with reference to findings of the baseline survey.
2.4
If, during the pre-operation phase
monitoring, observations of any die-off / abnormal conditions of the tagged corals are made, the ET will
inform the Contractor, Independent Environmental Checker (IEC)/ Environmental Project Office
(ENPO), Agriculture, Fisheries and Conservation Department (AFCD) and in liaison with AFCD investigate any measures
needed.
2.5
Monitoring result will be reviewed and
be compared against the Action Level and Limit Level (AL/LL) as set out in Table 2-1. Actions
specified on Table 2-2 will be taken by ET, IEC, SOR and Contractor shall there be exceedance of
AL/LL
Table 2-1 Action and Limit Levels for Pre-Operation Phase Coral Monitoring
|
Parameter |
Action Level Definition |
Limit Level Definition |
|
Mortality |
If
during Impact Monitoring a 15% increase in the percentage of partial
mortality on the corals
occurs at more
than 20% of the tagged indirect impact site coral colonies that is not recorded on the tagged corals at the control site, then the Action Level is exceeded |
If
during Impact Monitoring a 25% increase in the percentage of partial
mortality on the corals
occurs at more
than 20% of the tagged indirect impact site coral colonies that is not recorded on the tagged corals at the control site, then the Limit Level is exceeded |
Note:
If the defined Action Level or Limit Level for coral monitoring is exceeded, the actions as set out in Table 5-4 will be
implemented.

3. Result
3.1. The pre-operation phase monitoring for December 2023 pre-operation
phase monitoring were performed on 28th
December 2023 for both Indirect Impact Sites and Control Site (Figure 3 and 4); and the
weather conditions were summarized in Table 3.1.

3.2. Ten (10) hard coral colonies in C2, C3 and C8 were monitored at each site of Control
and Indirect Impact sites as
suggested in the Operation Phase Monitoring Plan. The general health conditions (size, mortality, bleaching and sediment) were recorded and summarized
in Table 3.2, Table 3.3
and Table 3.4. Photos of each tagged coral colonies were taken during the monitoring activities
and shown in Appendix A (Photo Plate A, B and C)..
3.3. All tagged coral colonies showed good health condition during the
December 2023 Monitoring. There was not
increased level of mortality, bleaching and sediment in other tagged coral colonies when
compared with the baseline results.

4. Discussion and Conclusion
4.1
The
pre-operation coral monitoring for December 2023 survey were carried out in the indirect impact area (C2 and C3) and control site (C8) on 28th
December 2023. A
total of 30 tagged coral colonies (10 at control
site and 20 and two indirect impact
sites) were monitored. All coral colonies
were good in
general.
4.2
No sediment, bleaching or increased
mortality in the general condition of all other tagged coral colonies were observed during the pre-operation
phase monitoring period. No
deterioration of the coral community was observed in the ecological monitoring results when compared with the baseline ecological monitoring
results. There is no AL/LL exceedance during the monitoring period. Photos of each tagged corals colonies
were taken and shown in Appendix A (Photo Plates A, B and C).

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.
