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.

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. As no Contract-related construction activities were undertaken in the reporting month within a radius of 300m from the monitoring stations as shown in Figure 2.4, no impact noise monitoring was conducted in the reporting period.
Figure 2.4 Site Layout Plan with Noise Sensitive Receivers and Desalination Plant
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 Pre-operation 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.

Sampling Frequency
Pre-operation phase
3.14. Impact water quality monitoring were carried out three days per week during the commission 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.
Sampling Depths & Replication
3.15. 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
Pre-operation phase
3.16. 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 3.4.

Monitoring Results and Observations
Construction Phase
3.17. 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.
Pre-operation phase
3.18. 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
3.19. The additional marine water quality monitoring was conducted at the thirteen monitoring stations on 2, 4, 6, 9, 11, 13, 16, 18, 20, 23, 25, 27 and 30 April 2024.
3.20. Thirty-eight (38) of the pre-operation phase water quality monitoring results of SS obtained had exceeded the Action Level. Twenty-two (22) of the pre-operation phase water quality monitoring results of SS obtained during the reporting period had exceeded the Limit Level.
3.21. Investigation on the reason of exceedance has been carried out, where the exceedances of SS on 2, 4, 6, 9, 11, 13, 16, 18, 23, 25, and 27 April 2024 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.
3.22. Monitoring results of 8 key parameters: Salinity, DO, turbidity, SS, pH, temperature, Total Residual Chlorine and Iron in this reporting, are summarized in Table 3.5, 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
Monitoring Parameters
5.7. The landfill gas monitoring parameters and the action and limit level are summarized in

MONITORING
RESULTS AND OBSERVATIONS
5.10. In this reporting period, 156 times of landfill gas monitoring were periodically conducted during excavations at 300mm to 1m depth within the consultation zone and whenever workers entered the excavation on the day at TKO Area 137 (Ch1+120 - Ch1+800) until 20 April 2024. No exceedances of action level and limit level was observed.
Monitoring Requirements
6.1. In accordance with Section 8.1 of the EM&A Manual, weekly site audit shall be carried out by the ET include checking whether good site practices are being properly implemented by the Contractor and the extent of the works area within the Clear Water Bay Country Park should be checked by the ET during the weekly site audit.
Site Inspection
6.2. Weekly site audit was carried out by the ET in the reporting month, no trespass by the Contractor outside the works area of the Project and Clear Water Bay Country Park, and no damage to the vegetation and rocky shore outside the Project area was observed in the reporting month. Retained trees was properly protected during the construction works, no unacceptable construction works was observed.
6.3.
If non-compliance were found
during the construction works, the actions in accordance with the Event and
Action Plan will be carried out according to Appendix E.
7.1. Under the approval conditions of the EIA Report for the Project, an EM&A programme on coral for the pre-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 Pre-Operation Baseline Coral Monitoring and Regular Coral Monitoring Methodology.
Monitoring Location
7.2. 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 7.1 should be monitored during the pre-operation Phase. Pre- 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 pre- operation phase and operation phase.

Monitoring Result
and Observation
7.6. Pre-operation phase coral monitoring works was conducted on 17 April 2024. No sediment, bleaching or increased mortality in the general condition of all tagged coral colonies were observed during the monthly 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.
7.7. The details of the monitoring carried out on 17 April 2024 is presented in Appendix I.

Ecology (Fishery Monitoring)
8.1. The purpose of the pre-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
8.2. 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.
8.3. 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).
8.4. 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.
8.5. 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.
8.6.
The coordinates of the proposed monitoring locations are shown in Figure 8.1.
Figure 8.1 Monitoring location
of regular fishery
monitoring during pre-operation Phase
Monitoring Frequency
8.7. Pre-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
8.8. Pre-operation phase fishery monitoring for dry season 2024 was carried out on 17 and 24 February 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 detailed result of the monitoring is presented in Appendix I.

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. |

1.1.5
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.

Methodology
2.1 All tagged coral colonies in C2, C3 and C8 will
be monitored monthly
during the first-year operation of TKODP. 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 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

Discussion and Conclusion
4.1
The April 2024
coral monitoring survey were carried out in the indirect impact area (C2 and
C3) and control site (C8) on 17th April 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.
4.2
No sediment,
bleaching or increased mortality in the general condition of all other tagged
coral colonies were observed during
the monthly 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).

1.1.4
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 on 4 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
1.2.1
An Environmental
Monitoring and Audit (EM&A) programme of regular fisheries monitoring is
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

Summary of EIA Findings and Updated Fisheries Survey
2.1.1
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 fisheries resources 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.
2.1.2
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 of the 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 are presented in the ?œConsultancy Services for Updated Fisheries Survey for Tseung Kwan O
Desalination Plant Final Report??issued by ERM on 6 June 2017.

Monitoring Methodology
3.1
Monitoring Parameters and Programme
The
purpose of this baseline fisheries monitoring programme is to update the
information onfisheries resources in Joss House Bay and nearby water before
commencement of the Project construction.
Under the baseline 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).

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

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 and
diversity 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 water depth) 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 concentrated and 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 to collect ichthyoplankton. A flow meter was fitted at mouth of the net to record the volume of water 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 the water 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 were recorded and identified to the lowest taxonomic level,
where possible. Larval fish individual without
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 (weight of
fish per survey time and number of nets or cages).

Supplementary Baseline Water Quality Monitoring Methodology
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 (¢XC)
- 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)
Four
water quality monitoring events covering dry and 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 baseline water quality monitoring programme is provided
in Table 4-1 below.

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 samples for laboratory analysis were stored in
high density polythene bottles with no preservatives added, packed in ice (cooled to 4¢XC 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 provided in Table 4-4.

For
all the above survey methods, monitoring locations were recorded using
global positioning system (GPS). During each monitoring event, the field
conditions and observations (e.g. weather conditions, water depth (m) and
temperature (¢XC) etc.) were recorded
at each monitoring location. All field surveys were conducted during
daytime.

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 12 fish species recorded,
9 species are classified as commercial species,
which accounted for about 73.3% of the total
biomass and 82.6% of the total abundance from thecaptured adult fish species. Most of these commercial species
are of medium to low commercial value (45.1% of total abundance). However, high commercial value fishes showed only 28.2% in terms of total biomass. The dominant
species in terms of abundance were Pearl-spot chromis (Chromis notata) which accounting for 29.4 % of total abundance. In terms of abundance, most of the adult fish resources in the
Study Area are of low to no commercial value, accounting for > 67% of total
abundance of overall adult fish resources. However, in term of biomass, most of
the adult fish resources in the Study Area are also of low to no commercial
value, accounting for > 57% of total biomass of overall adult fish resources.

(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.

Supplementary Water Quality Monitoring Results
9.1 The statistical summary
of the water quality monitoring parameters during dry are tabulated
in Table
11.1. The detailed in-situ and
laboratory measurement result are shown in Appendix
A and Appendix B respectively.
9.2 The measured water
temperature values ranged
from about 21.93 ¢XC to about 23.28 ¢XC in dry 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 7.58 to 8.05 in both dry. 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 much more stable salinity and lower SS contents. No absolute SS and turbidity objectives in marine water are
available. The average SS and turbidity levels are below 5 mg/L and 7 NTU with
highest measured values of about 8 mg/L and 10 NTU respectively. No obvious
seasonal variation of SS and turbidity levels can be identified.
9.6 The average salinity levels measured
during both dry season are higher than 33 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 from the 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.

Conclusions
10.1 Pre-operation fisheries monitoring works for the Project including
adult fish, juvenile fish, ichthyoplankton and supplementary water quality surveys
were completed in February 2024.
10.2 For adult fish survey using cage trapping and gill netting, a total
7182 g of 108 individuals comprising 12 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 egg and 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 larvae family 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 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.

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 pre-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 2 April 2024, 4 April 2024, 6 April 2024,
9 April 2024, 11 April
2024 and 13 April 2024, seventeen (17) Action Level exceedances and eight (8) Limit Level exceedance were recorded during
mid-flood tide. Four
(4) Action Level exceedances and two (2)
Limit Level exceedance were recorded during mid-ebb tide. Total twenty-one (21)
Action Level and ten (10) Limit Level exceedances for SS of impact water
quality monitoring were recorded between 1
April to 15 April 2024.
The marine construction works were completed
on 1 September 2023. The commissioning activities were shown in the table below. The plant and the outfall shaft work normally.
After investigation, all exceedances were considered non-project related.
