A9. No noise
monitoring was conducted during the reporting period since there are no
project- related construction activities undertaken within a radius of 300m
from the monitoring locations. No exceedance of the Action Level was recorded
during the reporting period.
A10. 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.
A11. The operation
phase water quality was conducted from 1 September 2024 to 30 November 2024. Thirty-six (36) of the operation phase water quality monitoring results of SS obtained had

Noise
1.
Monitoring
Requirements
To ensure no
adverse noise impact, construction noise monitoring is recommended to be
carried out within 300m radius from the nearby noise sensitive receivers
(NSRs), during construction phase. The NSRs selected as monitoring station are
(i) NSR4 – Creative Secondary School, (ii) NSR24 –
PLK Laws Foundation College, and (iii) NSR31 – School of Continuing and
Professional Studies – CUHK respectively.
No impact
construction noise monitoring was conducted in the reporting period due to the
overly distant monitoring station from the works location, where they were
farther than 1 km from the closet monitoring station NSR4 to the works
location.

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

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

WATER QUALITY
In accordance with the recommendations of
the EIA, water quality monitoring is required during dredging for the submarine
pipelines and, during operation phase. In addition, baseline water quality
monitoring was conducted prior to the commencement of marine construction
activities.
The following Section provides details of
the water quality monitoring to be undertaken by the Environmental Team (ET) to
verify the distance of sediment and brine plume dispersion and to identify
whether the potential exists for any indirect impacts to occur to ecological
sensitive receivers. The water quality monitoring programme
was carried out to allow any deteriorating water quality to be readily detected
and timely action taken to rectify the situation.
Water quality monitoring for the Project can be
divided into the following stages:
·
Dredging
activities during construction phase;
·
Discharge
of effluent from main disinfection during construction phase;
·
Operation
phase – first year upon operation; and,
·
Continuous
monitoring of effluent quality.

Monitoring
Results and Observations
Construction
Phase
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.
Operation
Phase
The first-year operation phase marine
water quality monitoring was carried out during the reporting period, the
monitoring was conducted 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 5.4 First-year
Operation Phase Marine Water Monitoring.
The operation phase marine water
quality monitoring was conducted on 3, 7, 10, 12, 14, 17, 19,
21, 24, 26 and 28 September 2024
, 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29 and 31 October 2024
and 2, 5, 7, 9, 12, 16, 19, 21, 23, 26, 28 and 30 November 2024. The result of the reporting quarterly is
presented in Table 3.6.
Thirty-six (36) of the operation phase marine water quality monitoring results of SS
obtained had exceeded the Action Level. Eighty-five (85) of the operation phase water quality monitoring results of SS obtained
during the reporting period had exceeded the Limit Level.
Investigation on the reason of exceedance
has been carried out, where the exceedances of SS were concluded to be
unrelated to the Contract as detailed in the Incident Reports on Action Level
or Limit Level. Summary of the exceedance is presented in Appendix E.
Continuous
Monitoring of Effluent Quality
Continuous Monitoring of Effluent Quality
was conducted sampling point in the reporting period. No exceedance of the sampling was obtained during the
reporting period had exceeded the Limit Level. The detailed results are
summarized in Table 3.7.
The plant was shut down from 7 a.m. to 7
p.m. on 3 November 2024. No effluent discharge from TKODP occurred during this
period.
Due to the plant has suspended production,
there was no effluent discharge from the TKODP during the period between 24
November 2024 and 30 November 2024.

* Remark: As confirmed by various
laboratories in Hong Kong, the lowest detection limit for Sodium Metabisulphite is <2 mg/L. Due to the limitation of the
laboratory, the lowest result for Sodium Metabisulphite
will only be shown as < 2 mg/L.

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

LANDFILL GAS MONITORING
1.
Monitoring
Requirement
In accordance with
Section 11 of the EM&A Manual, monitoring of landfill gas is required for
construction works within the 250m Consultation Zone. Part of the desalination
plant and the indicative area of natural slope mitigation works fall within the
SENT Landfill Extension Consultation Zone; and part of the 1,200 mm diameter
fresh water mains along Wan Po Road falls within the SENT Landfill and SENT
Landfill Extension Consultation Zones, TKO Stage II/III Restored Landfill and
TKO Stage I Restored Landfill Consultation Zones.
Routine monitoring
is required at buildings within the Project Site and consultation zones. The
monitoring frequency will be monthly for the first year of operation.
For 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.
Monitoring of
oxygen, methane, carbon dioxide and barometric pressure would be performed
monthly during the operation phase.
2.
Monitoring
Location
Monitoring of
oxygen, methane, carbon dioxide and barometric pressure was performed for
excavations at 1m depth or more within the consultation Zone.
During
construction of works within the consultation zones, excavations of 1m depth or
more was monitored:
§
At
the ground surface before excavation commences;
§
Immediately
before any worker enters the excavation;
§
At
the beginning of each working day for the entire period the excavation remains
open; and
§
Periodically
through the working day whilst workers are in the excavation.
For excavations between 300mm and 1m deep,
measurements should be carried out:
§
Directly
after the excavation has been completed; and
§
Periodically
whilst the excavation remains open.
3.
Monitoring
Parameters
LFG monitoring was carried out to identify any migration between the
landfill and the Project and to ensure the safety of the construction,
operation and maintenance personnel working on- site, visitors and any other
person within the Project area.
The
following parameters were monitored:
§
Methane.
§
Oxygen.
§
Carbon
Dioxide.
§
Barometric
Pressure.

No noise monitoring was conducted during
the reporting period since there are no Contract- related construction
activities undertaken within a radius of 300m from the monitoring locations. No
Action Level exceedance was recorded during the reporting period.
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.
Thirty-six (36) of the operation phase water quality monitoring results of SS obtained had
exceeded the Action Level. Eighty-five
(85) of the
operation phase water quality monitoring results of SS obtained during the
reporting period had exceeded the Limit Level. After investigation, all
exceedances were considered non-project related.
In this reporting period, 132 times of Construction Phase landfill gas monitoring were
recorded at Wan Po Road (Ch0+390 – Ch0+780) and (Ch0+400 - Ch1+200). No
exceedance of action and limit levels for methane, oxygen and carbon dioxide
was observed. Monitoring was conducted during excavations at 1m depth or more
within the consultation zone and whenever workers entered the excavation on the
day. The landfill gas monitoring was ceased from 31 October 2024.
In this reporting period, Operation Phase
landfill gas monitoring was conducted on 25, 26 and 27 September 2024, 9 and 10 October 2024
and 14, 15 November 2024. No
exceedances of action level and limit level was observed.
Operation phase monthly coral monitoring
was conducted during the reporting period on 18 September 2024, 21 October 2024 and
11 November 2024. No
sediment, bleaching or increased mortality in the general condition of all
other tagged coral colonies were observed during the monthly operation phase

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. |
