Monitoring Equipment

a) Operation phase Marine Water Quality Monitoring

2.8. 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.

Sampling Frequency

a) Impact Marine Water Quality Monitoring

2.18. Water quality monitoring was carried out three days per week during the operation 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.

b) Continuous Monitoring of Effluent Quality

2.19. The effluent should be collected in a full 24-hour period. Twenty four-hour flow- weighted composite effluent sample for subsequent chemical analysis and testing should be prepared by the following procedures:

- Collect effluent sub-sample at bi-hourly interval over a 24 hour period

- Obtain flow record of the Project for the 24-hour sampling period

- Calculate the volume of each sub-sample for preparation of flow-weighted composite sample

- Transfer the appropriate volume of sub-samples to a clean container and mix thoroughly

Sampling Depths & Replication

a) Operation phase Marine Water Quality Monitoring

2.20. During 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.

b) Continuous Monitoring of Effluent Quality

2.21. The effluent sampling should be planned carefully to ensure appropriate volume of effluent sub-samples is collected to prepare sufficient amount of flow-weighted composite effluent sample for carrying out subsequent chemical analysis and testing.

Action and Limit Levels

2.22. 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 2.7 and Table 2.8.

Monitoring Results and Observations

a) Operation phase Marine Water Quality Monitoring

2.23. The operation phase of Tseung Kwan O Desalination Plant was commenced on 1 July 2024. Marine water quality monitoring for the operation phase of Tseung Kwan O Desalination Plant was conducted in the reporting period at the thirteen monitoring stations (CE, CF, WSR1, WSR2, WSR3, WSR4, WSR16, WSR33, WSR36, WSR37, NF1, NF2 and NF3). The

Action and Limit Level would be referred to the approved EM&A Manual Table 2.7.

2.24. The marine water quality monitoring was conducted at the thirteen monitoring stations on 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29 and 31 October 2024.

2.25. Seventeen (17) of the operation phase water quality monitoring results of SS obtained had exceeded the Action Level. Twenty-nine (29) of SS obtained during the reporting period had exceeded the Limit Level.

All plants were observed to be in satisfactory condition in the reporting month.

5.3. If non-compliance were found during the operation phase, the actions in accordance with the Event and Action Plan will be carried out according to Appendix D.

6. Ecology (Coral Monitoring)

6.1. Under the approval conditions of the EIA Report for the Project, an EM&A programme on coral for the operation phase of the Project is recommended. Pursuant to these EIA approval conditions and Condition 3.1 of the EP and FEP, details of the regular coral monitoring programme have been proposed based on the baseline coral monitoring results in the Report on operation Baseline Coral Monitoring and Regular Coral Monitoring Methodology.

Monitoring Location

6.2. In accordance with Appendix B Section 5.1 of the approved supplementary EM&A Manual, two indirect impact sites (C2 and C3) and one control site (C8) as shown in Figure 6.1 should be monitored during the operation Phase. Operation coral survey should be conducted at the indirect impact and control sites. Ten selected hard coral colonies with similar species should be tagged at each of the control and indirect impact sites before commencement of the operation phase. Tagged hard coral colonies should be monitored in open waters during the operation phase.

Figure 6.1 Spot Dive Check Areas Two Proposed Indirect Impact Sites (C2 and C3) and one control site (C8) during Operation Phase

Action and Limit Levels

6.3. 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 6.1.

Table 6.1 Action and Limit Level for Coral Monitoring Equipment

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 E3 will be implemented.

6.4. If non-compliance were found during the opertaion works, the actions in accordance with the Event and Action Plan will be carried out according to Appendix D.

Monitoring Frequency

6.5. Operation phase coral monitoring shall be monitored once per month as the requirement of the first year of operational phase.

Monitoring Result and Observation

6.6. Operation phase coral monitoring works was conducted on 21 October 2024. 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. The detail of the monitoring is presented in Appendix H.

7. Ecology (Fishery Monitoring)

7.1. The purpose of the operation phase regular fisheries monitoring programme is to monitor the potential impacts on fisheries resources in the vicinity of the project site. Apart from the regular fisheries monitoring programme, a water quality monitoring programme in addition to the water quality monitoring programme in the approved EM&A Manual is also described in Section 2.4 to (i) provide supplementary information in the interpretation of the findings of the fisheries monitoring and (ii) assist the monitoring of the potential impact on the Tung Lung Chau Fish Culture Zone (FCZ) in Joss House Bay.

Monitoring Location

7.2. In accordance with Section 2.3 of the approved Methodology Paper on Regular Fisheries Monitoring, it is recommended to set up six (6) fisheries monitoring locations in Joss House Bay and its vicinity to monitor the fisheries resources.

7.3. Two (2) sampling locations are set up in close proximity of the direct footprint of the proposed submarine utilities around TKO Area 137. These sampling locations represent the potential Project impact zones (i.e. areas at and in close proximity to the footprint of the proposed submarine utilities that will be directly affected by the Project works).

7.4. Two (2) gradient locations are proposed between the proposed submarine utilities and Tung Lung Chau FCZ to assist in the interpretation and identification of any potential fisheries impact in the vicinity of the FCZ.

7.5. Two (2) reference locations are proposed in the outer Joss House Bay between the waters of Tung Lung Chau and Fat Tong Mun. These reference locations are further away and will not be affected by the Project discharge (based on the EIA prediction) and will serve as control stations. Any significant fisheries impact identified at the reference locations should be caused by other natural factors or non-Project activities. The trends of fisheries conditions recorded in the reference locations will be used to assist in the interpretation of the trends of fisheries impact identified in the impact and gradient locations.

7.6. The coordinates of the proposed monitoring locations are shown in Figure 7.1.

Figure 7.1 Monitoring Location of Regular Fishery Monitoring during Operation Phase

Monitoring Frequency

7.7. Operation phase fishery monitoring shall be carried out 2 times in wet season (April to October) and 2 times in dry season (November to March) to examine the following:

- Fish species composition;

- Abundance: number of fish captured;

- Diversity of fish resources: species diversity and evenness;

- Size: range of total length; Biomass in weight; and

- Values of catches of commercial species: catch per unit effort (CPUE) and yield per unit effort (YPUE).

Monitoring Result and Observation

7.8. Operation phase fishery monitoring for wet season 2024 was carried out on 24 and 31 August 2024. The survey findings showed that the abundance and diversity of fish eggs and larvae are on the low side for the Study Area, and the abundance and diversity of juveniles are very low for the Study Area. Survey findings also showed that there was a very week relationship in recorded families between ichthyoplankton assemblages, adult fish and juvenile fish in the Study Area, which implies that the Study Area does not appear to be an important spawning or nursery grounds for commercial fishes. The detail of the monitoring is presented in Appendix H.

1 INTRODUCTION

1.1 Background

1.1.1 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/B) for the construction and operation of the Project.

1.1.2 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 (TKODP) under Contract No. 13/WSD/17 (the Project).

1.1.3 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.

1.1.4 The proposed Desalination Plant at Tseung Kwan O (TKODP) 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.

1.1.5 A baseline coral survey was conducted in October 2023 to verify the validity of the pervious EIA findings as well as to provide updated coral data for impact monitoring during the construction and operation 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 during the first year of Project 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 operation phase monitoring surveys should be reviewed with reference to findings of the baseline survey.

2.4 If, during the 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 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.

1 Introduction

1.1 Background

Water Supplies Department (WSD) appointed Black & Veatch Hong Kong Limited (B&V) to undertake the consultancy “Agreement No. CE 8/2015 (WS) First Stage of Desalination Plantat Tseung Kwan O - Investigation, Design, and Construction” on 16 November 2015.

The purpose of the Project is to construct a sea water reverse osmosis (SWRO) desalination plant at Tseung Kwan O (TKO) Area 137, together with all ancillary facilities and the slope mitigation works in the adjoining Clear Water Bay Country Park.

The first stage of the proposed SWRO desalination plant will have a water production capacity of 135,000 cubic meters (m3) per day with provision for future expansion to the ultimate capacity up to 270,000 m3 per day when necessary.

The Project is classified as a Designated Project (DP) under the Environmental Impact Assessment Ordinance (EIAO). An Environmental Impact Assessment (EIA) was completed in accordance with the EIAO under the Feasibility Study (FS) stage of the Project. The EIA Report for the Project (Register No.: AEIAR-192/2015) was approved with conditions on 4 November 2015 under the EIAO. Following the approval of the EIA Report, the Environmental Permit (EP) (No: EP- 503/2015), covering the construction and operation of Project, was granted on4 December 2015. The EP for this Project was subsequently amended and the amended EP (No. EP-503/2015/B) was granted on 3 April 2024 under the EIAO. Baseline fisheries monitoring was conduction in September 2018 to February 2019

1.2 Purpose of this Report

An Environmental Monitoring and Audit (EM&A) programme of regular fisheries monitoringis recommended under the approval conditions of the EIA Report for the Project. The purpose of the EM&A programme is to monitor the fisheries impact of the Project. Pursuant to these EIA approval conditions, details of the regular fisheries monitoring programme shall be submitted to the Director of Environmental Protection (DEP) for prior approval.

The regular fisheries monitoring programme including the methodologies for carrying out adult fish survey, juvenile fish survey, ichthyoplankton survey and supplementary water quality monitoring during the pre-construction (or baseline period), construction, pre-operation and operational stages of the Project are presented in the “Final Methodology Paper on Regular Fisheries Monitoring” issued by B&V on 31 August 2018. The dry season of the first year construction works were subsequently carried out in 29^th and 30^th March 2021. This Report is prepared to present the progress of the regular operation phase fisheries monitoring.

2 Summary of EIA Findings and Updated Fisheries Survey

This Project comprises submarine utilities including a seawater intake and a submarine outfall in Joss House Bay. The approved EIA Report predicted that the potential impacts on fisheriesresources would be confined within close proximity of these submarine utilities. No important fish spawning and nursery grounds were identified near the proposed submarine utilities with reference to the findings of literature review undertaken during the EIA stage. The EIA Report concluded that no significant fisheries impact would arise from construction and operation of the proposed submarine utilities.

In accordance with Condition 2.9 of the EP, an Updated Fisheries Survey was carried out in 2015 to 2016 to verify if any significant fish spawning and nursery grounds in the vicinity ofthe proposed submarine utilities. The Updated Fisheries Survey revealed no important fish spawning and nursery grounds near the proposed submarine utilities and affirmed the conclusion made in the approved EIA Report. The results of the Updated Fisheries Survey arepresented in the “Consultancy Services for Updated Fisheries Survey for Tseung Kwan ODesalination Plant Final Report” issued by ERM on 6 June 2017.

3 Monitoring Methodology

3.1 Monitoring Parameters and Programme

The purpose of this fisheries monitoring programme is to update the information on fisheries resources in Joss House Bay and nearby water during Tseung Kwan O Desalination Plant operation. Under the monitoring programme, survey on adult fish, juvenile fish and ichtyoplankton were carried out 2 times in wet season and 2 times in dry season to examine the following:

- Fish species composition;

- Abundance: number of fish captured;

- Diversity of fish resources: species diversity and evenness;

- Size: range of total length;

- Biomass in weight; and

- Values of catches of commercial species: catch per unit effort (CPUE) and yield per unit effort (YPUE).

A summary of the baseline fisheries monitoring programme is provided in table below.

Table 3-1: Operation Phase Fisheries Monitoring Programme

Monitoring	Method	Operation Phase Fisheries Monitoring Dates
		Wet Season
		Event 1	Event 2
Adult Fish Survey	Gill Netting and Cage Trapping	24 August 2024	31 August 2024
Juvenile Fish Survey	Purse-seining	24 August 2024	31 August 2024
Ichtyoplankton Survey	PlanktonTowing	24 August 2024	31 August 2024

3.2 Fisheries Resource Sampling Locations

Six (6) fisheries sampling locations were set up in Joss House Bay and its vicinity to monitor the baseline fisheries resources.

Two (2) sampling locations were set up in the Impact Area (IPA) in close proximity of the direct footprint of the proposed submarine utilities around TKO Area 137.

Two (2) sampling locations were set up in the Gradient Area (GDA) between the proposed submarine utilities and Tung Lung Chau Fish Culture Zone (FCZ).

Two (2) reference locations were set up in the Control Area (CLA) in outer Joss House Bay between the waters of Tung Lung Chau and Fat Tong Mun. These reference locations are further away from the Project discharge (based on the EIA prediction) and will serve as control stations.

The baseline fisheries resource sampling locations are summarized in Table 3-2 and shownin Figure 3.1.

Juvenile Fish Survey	P1, P2	G1, G2	R1, R2
Ichtyoplankton Survey	T1, T2	T5, T6	T3, T4

Figure 3.1 Fisheries Resources Monitoring Locations

3.3 Adult Fish Survey Methodology

Two fishing methods, gill netting and cage trapping, were used to sample pelagic and demersal adult fish resources at each sampling location. These methods are also commonly used by local fishermen in Hong Kong waters.

Pelagic Fish Survey - Gill Netting

Under each sampling event, a pair of trammel (gill) nets was deployed for one (1) hour at each sampling location. The nets were 1 m deep, 30 m in length and comprised of three (3) layers,with two 20 cm mesh stretches sandwiching a 5 cm mesh stretch. All fish species captured were recorded and identified to species level as far as practicable. Each gill netting survey was analysed for species composition, abundance, size (total length), biomass in weight and diversity of adult fish.

Demersal Fish Survey - Cage Trapping

Two sets of four metal wire cage traps, each ranged from 0.8 to 0.9 m3 in volume and mesh size of 25 mm, were deployed for one (1) hour at each sampling location. Distance between the traps was about 10 m, and the distance between each set of traps was about 100 m. Breador other suitable fish bait was used as bait for cage trapping. All species caught in the cage trapping survey were identified to species level as far as practical. Each cage trapping surveywas analysed for species composition, abundance, size (total length), biomass in weight anddiversity of adult fish.

3.4 Juvenile Fish Survey Methodology

A typical purse-seine fishing method was used to sample juvenile fish at each sampling location. The nets adopted in the survey ranged from 5 to 15 m deep (depending on the waterdepth) and were 50 m in length, and with 6 mm mesh size (maximum stretched). For each sampling event, both a mother boat and a P4 sampan were deploy the seine net for approximately 30 to 45 minutes, with each boat holding one end of the net. The nets were pulled towards the fish resources in the form of a semi-circle. Fish catches were concentratedand lifted onto the mother boat. All fishes captured were recorded and identified to species level as far as practicable.

3.5 Ichthyoplankton Survey Methodology

To investigate spatial and seasonal or temporal variation of fish egg and fish larvae composition, ichthyoplankton survey was conducted at each sampling transect using plankton towing to collect representative samples.

A bongo plankton net, of 50 cm mouth diameter and with 0.5 mm mesh size, was deployed tocollect ichthyoplankton. A flow meter was fitted at mouth of the net to record the volume ofwater filtered.

At each site, three (3) replicate tows were conducted, and each tow with a duration of 15 minutes. The net was deployed in a single oblique tow to a depth of 2m off the seabed and towed at a speed of 1-2 knots. Consequently, the net was gradually winched up towards thewater surface in order to sample the entire water column.

The plankton was immediately fixed in 70% ethanol. The ichthyoplankton was sorted, number counted and size range measured in the laboratory. All fish egg and fish larvae captured wererecorded and identified to the lowest taxonomic level, where possible. Larval fish individualwithout distinctive morphological features for taxonomic identification were examined with the aid of DNA sequencing if deemed necessary. Species composition, abundance and diversity of species were measured to describe and compare temporal and spatial changes.

3.6 Data Analysis

Data collected under each fisheries monitoring event were analyzed to assess the spatial and temporal variations of species abundance and total biomass (for adult and juvenile fish)/ density (for ichthyoplankton). Temporal (wet vs. dry) and spatial (e.g. Impact Area vs. Control Area) differences in fish abundance were compared using descriptive statistics and/ or inferential statistics (Microsoft Excel and/or Statistical Package for the Social Sciences (SPSS)), followed by multiple comparison procedures, as appropriate. Diversity of fish resources was presented as species richness, Shannon-Weiner diversity (H’) and Pielou’s evenness (J’). Patterns of fish species composition are presented and subject to statistical analyses as above. Values of catches of commercial species for adult and juvenile fishes are presented in terms CPUE (number of individuals per fishing

time and number of nets or cages) and YPUE (weightof fish per survey time and number of nets or cages).

4 Supplementary Baseline Water Quality MonitoringMethodology

4.1 Monitoring Parameters and Programme

Supplementary baseline water quality monitoring (in addition to those specified in the EM&A Manual) was carried out at the same frequency and locations of the baseline fisheries monitoring programme. The water quality monitoring parameters include the following:

In-situ measurements:

- Water Depth (m)

- Temperature (°C)

- pH

- Dissolved Oxygen (DO) (mg/L)

- Turbidity (NTU)

- Salinity (ppt) Laboratory Analysis:

- Suspended Solid (SS) (mg/L)

- Iron (Fe) (mg/L)

- Total Residual Chlorine (TRC) (mg/L)

- Anti-scalant ’ACUMER’ 4035

(Anti-scalant water quality testing will only be conducted whenever anti-scalant dosage is adopted)

Two water quality monitoring events covering wet seasons were carried out. Undereach event, in- situ measurements and water sampling were taken at both mid-flood and mid-ebb tides. A summary of the water quality monitoring programme is provided in Table 4-1 below.

Table 4-1: Supplementary Water Quality Monitoring Programme

Monitoring Event	Season	Date	Tidal Status
Event 1	Wet Season	24 August 2024	Mid-ebb and Mid-flood
Event 2	Wet Season	31 August 2024	Mid-ebb and Mid-flood

4.2 Monitoring Locations

Supplementary water quality monitoring was conducted at all the six (6) adult andjuvenile fish sampling locations as shown in Figure 2.1 and summarized in Table 4-2.

At each location, water quality was monitored at 3 water depths (i.e. 1m below sea surface, mid- depth and 1 m above seabed).

4.3 Monitoring Methodology

Monitoring Equipment

The equipment used in the supplementary water quality monitoring is summarized in Table4-3.

Table 4-3: Monitoring Equipment

Equipment	Model
Water Sampler	Kahlsico Water Samplers
Multi-parameter Water Quality System	YSI ProDSS (S/N : 24G101660)

Sampling Procedures

Water depth was measured at each monitoring location and the levels of the three monitoring depths were then determined. At each monitoring depth, two replicate measurements of temperature, pH, DO, turbidity and salinity were taken in-situ and two replicate water samples were collected for laboratory analysis of SS, Fe and TRC. Following collection, water samplesfor laboratory analysis were stored in high density polythene bottles with no preservatives added, packed in ice (cooled to 4°C without being frozen) and kept in dark during both on- temporary storage and delivery to the testing laboratory.

Laboratory Analytical Methods

The testing of SS, Fe and TRC were conducted by HOKLAS laboratory. (ALS Technichem (HK) Pty Ltd and/or Acumen Laboratory and Testing Limited). Quality assurance and control procedures were implemented to ensure quality and consistency in results. The testing methods and corresponding reporting limits are providedin Table 4-4.

6.2 Commercial Value of Adult Fish Resources

According the method used in “EIA Report for Expansion of Hong Kong Airport into a Three- Runway System (AAHK 2012)” and “Provision of Consultancy Services for Updated Fisheries Survey for Tseung Kwan O Desalination Plant Final Report (ERM 2017)”, commercial value of adult fish resources was estimated based on Fish Marketing Organisation’s (FMO) wholesaleprice in 2018 and subsequently ranked into three classes including: High (> 70 HK$/ kg); Medium (60 - 70 HK$/ kg); and Low (< 60 HK$/ kg) (1). Top ten species of commercial importance are summarized in Table 6-3.

Among the 13 fish species recorded, 11 species are classified as commercial species, which accounted for about 89.1% of the total biomass and 88.6% of the total abundance from thecaptured adult fish species. Most of these commercial species are of medium to high commercial value

(68.5% of total abundance). However, high commercial value fishes showed only 51.2% in terms of total biomass. The dominant species in terms of abundance were Threadfin porgy (Evynnis cardinalis) which accounting for 22.0 % of total abundance. In terms of abundance, most of the adult fish resources in the Study Area are of low to medium commercial value, accounting for 57.1% of total abundance of overall adult fish resources.

*Notes: H = High (> 70 HK$/ kg; M = Medium (60 - 70 HK$/ kg); L = Low (< 60 HK$/ kg);

(1) Three classes of wholesale prices were defined under ERM 2017 to indicate the commercial value of the fish resources. With reference to the Fish Marketing Organization Annual Report 2016 / 2017 (https://www.fmo.org.hk/download?path=15_58&id=15), there has been an increasing trend of wholesale prices over the years. As such, the ranges of wholesale prices established under ERM 2017 have been adjusted under this Studyto reflect the increases in the market prices over the years.

6.3 Catch per Unit Effort

The following equation is adopted to calculate Catch per Unit Effort (CPUE):

CPUE = No.of individual of fish

Fishing time (hour) x (Number of net and cage)

9 Supplementary Water Quality Monitoring Results

9.1 The statistical summary of the water quality monitoring parameters during dry are tabulated in Table 9-1. The detailed in-situ and laboratory measurement result are shown in Appendix E and Appendix F respectively.

9.2 The measured water temperature values ranged from about 28.11 °C to about 29.77 °C in wet season. No absolute Water Quality Objective (WQO) on marine water temperature is available. Seasonal variation of water temperatures was recorded from the monitoring as expected.

9.3 The sea is a large pH buffering system with high capacity to resist changes in pH. The pH of seawater is normally very stable. Localized changes of pH in seawater may occur due to industrial discharge or episodic event such as algal bloom. All the pH values are within the normal natural range in seawater and complied with the relevant WQO of 7.78 to 8.39 in wet season. No seasonal trend of pH is observed.

9.4 Dissolved oxygen (DO) is essential to fish and an important health indicator of the marine ecosystem. Higher water temperature would tend to decrease the solubility of DO in seawater. The measured DO levels are generally lower in wet season as compared to the values measured in dry season but all the measured DO values are considered high. The depth-averaged DO and bottom DO values measured during the dry season are all over 7 mg/L. Thus, the DO levels are good in both dry.

9.5 Unlike the north western water of Hong Kong, which is subject to strong seasonal influence from the freshwater discharges from Pearl River Delta with high suspended solids (SS) content, the monitoring stations of this Study are located in the eastern water of Hong Kong with muchmore stable salinity and lower SS contents. No absolute SS and turbidity objectives in marinewater are available. The average SS and turbidity levels are below 5 mg/L and 3 NTU with highest measured values of about 9 mg/L and 2.55 NTU respectively. No obvious seasonal variation of SS and turbidity levels can be identified.

9.6 The average salinity levels measured during wet season are lower than 32 ppt, which indicated that the water is purely oceanic water with no significant freshwater dilution during the monitoring periods. No seasonal variation of salinity levels can be identified fromthe monitoring results.

9.7 All the measured iron (Fe) and total residual chlorine (TRC) values were non-detected. No indication of industrial or trade effluent discharge is identified in the Study Area.

10 Conclusions

10.1 Operation fisheries monitoring works for the Project including adult fish, juvenile fish, ichthyoplankton and supplementary water quality surveys were completed in August 2024.

10.2 For adult fish survey using cage trapping and gill netting, a total 7182 g of 108 individuals comprising 11 fish species from 9 families was recorded. The dominant species in terms of biomass and abundance were Pearl-spot chromis (Chromis notata), and this species are of low commercial value. Within the Study Area, majority of commercial species recorded are of low commercial value with some species of medium to high commercial values also recorded. The overall commercial value of adult fish resources in the Study Area is low to moderate.

10.3 For juvenile fish survey, a total of 1420.3 g of 215 individuals comprising 1 species from 1 families was recorded. The dominant species in terms of biomass and abundance was Mugil sp., which is of low commercial value. The juvenile fish resources in the Study Area is considered to be of very low diversity and production level.

10.4 In the ichthyoplankton survey, a total of 13 species from 9 families (including both fish eggand fish larvae) were recorded in the Study Area, comprising 7 fish egg species from 4 families, and 6 fish larvae species from 5 families. The mean larvae density and total larvaefamily under the current Study are on the low side compared with the results reported in other areas of Hong Kong. The dominant species of fish egg and fish larvae were Evynnis cardinalis and Marbled rockfish Sebastiscus marmoratus, respectively. These dominant species are considered of medium to high commercial value.

10.5 The supplementary water quality monitoring showed that the dissolved oxygen (key water quality parameter for fish) and pH in the Study Area fully complied with the relevant water quality objectives. The suspended solids and turbidity in the Study Area were in generally low. Iron and total residual chlorine were not detected in the Study Area with no indication of industrial or trade effluent discharge. Overall, the baseline water quality was good in terms of the monitoring parameters.

10.6 Overall, the survey findings showed that the abundance and diversity of fish eggs and larvaeare on the low side for the Study Area, and the abundance and diversity of juveniles are verylow for the Study Area. Survey findings also showed that there was a very week relationshipin recorded families between ichthyoplankton assemblages, adult fish and juvenile fish in theStudy Area, which implies that the Study Area does not appear to be an important spawning or nursery grounds for commercial fishes.

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) No exceedances of SS at S.P.1 in the daily continuous effluent monitoring.

Conclusion:

During water quality monitoring on 3,5, 10, 12, and 15 October 2024, two (2) Action Level and six (6) Limit Level exceedances were recorded during mid-flood tide and four (4) Action Level and three (3) Limit Level exceedances were recorded during mid-ebb. Total six (6) Action Level and nine (9) Limit Level exceedances for SS of impact water quality monitoring were recorded between 1 October to 15 October 2024.

The marine construction works were completed on 1 September 2023. The commissioning activities were shown in the table below. The desalination plant and the outfall shaft work normally.

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