of the results measured by direct reading method at 2-month intervals
throughout all stages of the air quality monitoring.
24-hour TSP Monitoring
Instrumentation
2.9
High volume samplers (HVS) (TISCH Model: TE-5170 and GMW Model: GS2310)
completed with appropriate sampling inlets were employed for 24-hour TSP
monitoring. The sampler was composed of
a motor, a filter holder, a flow controller and a sampling inlet and its
performance specification complied with that required by USEPA Standard Title
40, Code of Federation Regulations Chapter 1 (Part 50).
2.10
The positioning of the HVS samplers are as follows:
●
A horizontal platform with appropriate support to secure the samplers
against gusty wind shall be provided;
●
No two samplers shall be placed less than 2 meters apart;
●
The distance between the sampler and an obstacle, such as buildings,
must be at least twice the height that the obstacle protrudes above the
sampler;
●
A minimum of 2 metres of separation from walls, parapets and penthouses
is required for rooftop samplers;
●
A minimum of 2 metres of separation from any supporting structure,
measured horizontally is required;
●
No furnace or incinerator flue is nearby;
●
Airflow around the sampler is unrestricted;
●
The sampler is more than 20 metres from the dripline;
●
Any wire fence and gate, to protect the sampler, shall not cause any
obstruction during monitoring;
●
Permission must be obtained to set up the samplers and to obtain access
to the monitoring stations; and
●
A secured supply of electricity is needed to operate the samplers.
Operating/analytical procedures for
the operation of HVS
2.11
Operating/analytical procedures for the air quality monitoring are
highlighted as follows:
●
Prior to the commencement of the dust sampling, the flow rate of the
high-volume sampler was properly set (between 0.6 m3/min. and 1.7 m3/min.)
in accordance with the EM&A manual (AEIAR-173/2013). The flow rate shall be
indicated on the flow rate chart.
●
For TSP sampling, fiberglass filters with a collection efficiency of
> 99% for particles of 0.3μm diameter were used.
●
The power supply was checked to ensure the sampler worked properly. On sampling, the sampler was operated for 5
minutes to establish thermal equilibrium before placing any filter media at the
designated air monitoring station.
●
The filter holding frame was then removed by loosening the four nuts and
a weighted and conditioned filter was carefully cantered with the stamped
number upwards, on a supporting screen.
●
The filter was aligned on the screen so that the gasket formed an
airtight seal on the outer edges of the filter.
Then the filter holding frame was tightened to the filter holder with
swing bolts. The applied pressure should be sufficient to avoid air leakage at
the edges.
●
The shelter lid was closed and secured with the aluminium strip.
●
The timer was then programmed.
Information was recorded on the record sheet, which included the
starting time, the weather condition and the filter number (the initial weight
of the filter paper can be found out by using the filter number).
●
After sampling, the filter was removed and sent to the HOKLAS laboratory
(ALS Technichem (HK) Pty Ltd.) for weighing. The elapsed time was also recorded.
●
Before weighing, all filters were equilibrated in a conditioning
environment for 24 hours. The conditioning environment temperature should be
between 25°C and 30°C and not vary by more than ±3°C; the relative humidity
(RH) should be < 50% and not vary by more than ±5%. A convenient working RH
is 40%.
Maintenance/Calibration
2.12
The following maintenance/calibration is required for the HVS:
●
The high-volume motors and their accessories were properly maintained.
Appropriate maintenance such as routine motor brushes replacement and
electrical wiring checking was made to ensure that the equipment and necessary
power supply are in good working condition.
●
High volume samplers were calibrated at bi-monthly intervals using
TE-5025A Calibration
Kit throughout all stages of the air quality monitoring.
Results and Observations
2.13
The impact monitoring works for air quality monitoring locations AM1,
AM2, AM3 and AM4 are completed by the ET of Agreement No. CE 59/2015 (EP), and
the data will be adopted in this report. As the proposal for relocation
approved, the monitoring at AM4(A) will be conducted at AM4(B). For the time
being, as the station CKL2 for the 24 hr TSP monitoring, carried out under
EM&A works for Trunk Road T2 Project (EP- 451/2013), is located in close
proximity to AM4(B); the results from CKL2 are adopted as reference for the 24
TSP monitoring at AM4(B), which has similar environment when compared with that
for CKL2. The location of monitoring station CKL2 is shown in Figure 2.
2.14
The impact air quality monitoring was conducted at all five monitoring
stations as scheduled. The monitoring schedule is shown in Appendix D.
2.15
No Action Level exceedance was recorded for 24-hour TSP
monitoring in the reporting month and No Limit Level exceedance was recorded
for 24-hour TSP monitoring in the reporting month.
2.16
No Action/Limit Level exceedance was recorded for 1-hour TSP monitoring
in the reporting month.
2.17
The monitoring data and graphical presentations of 1-hour and 24-hour
TSP monitoring results are shown in Appendix

for 24-hour TSP monitoring in the reporting month.
Monitoring Requirements
2.
3.1
According to Section 3.2.1 of the EM&A Manual (AEIAR-173/2013),
construction noise monitoring was conducted to monitor the construction noise
arising from the construction activities. The regular monitoring frequency for
each monitoring station shall be on a weekly basis and conduct one set of
measurements between 0700 and 1900 hours on normal weekdays. Appendix A
shows the established Action and Limit Levels for the environmental monitoring
works.

Monitoring Methodology and QA/QC
Procedure
3.5
The monitoring procedures are as follows:
●
The monitoring station was normally be at a point 1m from the exterior
of the sensitive receivers building façade and be at a position 1.2m above the
ground.
●
For free field measurement, the meter was positioned away from any
nearby reflective surfaces. All records for free field noise levels were
adjusted with a correction of +3 dB(A).
●
The battery condition was checked to ensure the correct functioning of
the meter.
●
Parameters such as frequency weighting, the time weighting and the
measurement time were set as follows:
-
Frequency weighting: A
-
Time weighting: Fast
-
Time measurement: 30 minutes
●
Prior to and after each noise measurement, the meter was calibrated
using a Calibrator for 94.0 dB at 1000 Hz.
If the difference in the calibration level before and after measurement
was more than 1.0 dB, the measurement would be considered invalid and repeat of
noise measurement would be required after re-calibration or repair of the
equipment.
●
The wind speed was frequently checked with the portable wind meter.
●
At the end of the monitoring period, the Leq,
L90 and L10 were recorded. In addition, site conditions and noise
sources were recorded on a standard record sheet.
●
Noise monitoring would be cancelled in the presence of fog, rain, and
wind with a steady speed exceeding 5 m/s, or wind with gusts exceeding 10 m/s.
Supplementary monitoring would be provided to ensure sufficient data would be
obtained.
Maintenance and Calibration
3.6
The microphone head of the sound level meter and calibrator were cleaned
with a soft cloth at quarterly intervals.
3.7
The sound level meter and calibrator were checked and calibrated at
yearly intervals.
3.8
Immediately prior to and following each noise measurement the accuracy
of the sound level meter was checked using an acoustic calibrator generating a
known sound pressure level at a known frequency. Measurements were accepted as
valid only if the calibration levels from before and after the noise
measurement agree to within 1.0 dB.
Results and Observations
3.9
The data obtained from the impact monitoring works completed by the ET
of Agreement No. CE 59/2015 (EP) will be adopted in this report.
3.10
No Action Level exceedance was recorded due to the
documented complaint in the reporting month.
3.11
No Limit Level exceedance was recorded for day-time construction noise
monitoring in the reporting month.
3.12
Noise monitoring results and graphical presentations are shown in Appendix
G.

WATER QUALITY
Monitoring Requirement
Groundwater Quality
3
4
4.1
The existing groundwater quality monitoring programme has been suspended
as the monitoring results had been deemed non-representative of the impact from
the project justified by two major factors: (1) influence on the monitoring
results from non-project related factors, such as anthropogenic activities and
natural phenomenon; and (2) large separation between the monitoring stations
and works area. In addition, as no alternative locations for the groundwater
quality monitoring were available, the groundwater quality monitoring has been
suspended since October 2019 upon the agreement by EPD.
Marine Water Quality
4.2
According to Section 4.4.3 of EM&A Manual (AEIAR-173/2013), marine
water quality impact monitoring stations is carried out during marine
construction for TKOLTT reclamation. Since the construction of Cha Kwo Ling
Tunnel from the end of Trunk Road T2 to the TKOLTT at the Eastern Ventilation
Building does not involve reclamation, the marine water quality monitoring
programme stated in Section 4.4 of the EM&A Manual (AEIAR-173/2013) is
therefore not applicable to Contract No. ED/2018/04.
Groundwater Level Monitoring
(Piezometer Monitoring)
4.3
According to Section 4.1.2 of EM&A Manual (AEIAR-173/2013), daily
piezometer monitoring will be carried out on a daily basis when any tunnel
construction activities are carried out within +/- 50m of the piezometer gate
in plan. As the construction works of Cha Kwo Ling Tunnel from the end of Trunk
Road T2 to the TKOLTT at the Eastern Ventilation Building is approximately 120m
away from the piezometer gate in plan, the piezometer monitoring programme
stated in Section 4.2 of the EM&A Manual (AEIAR-173/2013) is therefore not
applicable to Contract No. ED/2018/04.
5.
WASTE MANGEMENT
5
5.1
According to Section 5.1.2 of the EM&A Manual (AEIAR-173/2013),
Waste materials generated during construction activities, such as construction
and demolition (C&D) materials and general refuse, are recommended to be
audited at regular intervals (at least quarterly) to ensure that proper
storage, transportation and disposal practices are being implemented by the
Contractor. To fulfil this requirement, site audits are carried out on a weekly
basis. The summaries of site audits are attached in Appendix I.
5.2
With reference to relevant handling records of this Project, the
quantities of different types of waste generated in the reporting month are
summarised and presented in Appendix H.
6.
ECOLOGY
6
6.1
Post-translocation monitoring survey is recommended in Section 6.2.5 of
the EM&A Manual (AEIAR-173/2013), to audit the success of coral
translocation. Since the construction of Cha Kwo Ling Tunnel from the end of
Trunk Road T2 to the TKOLTT at the Eastern Ventilation Building does not
involve any marine works in the concerned area mentioned in Section 6.1.2 of
the EM&A Manual (AEIAR-173/2013), the post-translocation monitoring survey
stated in Section 6.2.5 of the EM&A Manual (AEIAR-173/2013) is therefore not
applicable to Contract No. ED/2018/04.
7.
FISHERIES
7
7.1
According to Section 7.1.3 of EM&A Manual (AEIAR-173/2013), no
specific fisheries monitoring programme is required during the construction
phase.
7.2
The implementation of the mitigation measures stated in the Water
Quality Impact Assessment (Refer to Section 5 of EIA Report (AEIAR-173/2013))
will be audited as part of the EM&A procedures during the construction
period. The summaries of site audits are attached in Appendix I.
8.
CULTURAL HERITAGE
8
8.1
According to Condition 3.7 of EP-458/2013/C and Section 8.2.1 of the
EM&A Manual (AEIAR-173/2013), monitoring of vibration impacts was
conducted when the construction works are less than 100m from the Built
Heritage in close proximity of the worksite, namely the Cha Kwo Ling Tin Hau
temple. Tilting and settlement monitoring should be applied on the Cha Kwo Ling
Tin Hau Temple.
8.2
As the construction works of Cha Kwo Ling Tunnel from the end of Trunk
Road T2 to the TKOLTT at the Eastern Ventilation Building are located more than
100m away from the Cha Kwo Ling Tin Hau temple, the vibration impact monitoring
stated in Section 8.3.1 of the EM&A Manual (AEIAR-173/2013) is not
applicable to Contract No. ED/2018/04.
8.3
According to Condition 3.6 of EP-458/2013/C, to prevent damage to Cha
Kwo Ling Tin Hau Temple and its Fung Shui rocks (Child-given rocks) during the
construction phase, a temporarily fenced-off buffer zone (Rocks buffer zone is
5 m from the edge of Rocks and 15m from the edge of Rocks alter) with allowance
for public access (minimum 1 m) around the temple and the Fung Shui rocks shall
be provided. The open yard in front of the temple should be kept as usual for
annual Tin Hau festival.
8.4
As there is a large buffer distance from the current works to Cha Kwo
Ling Tin Hau Temple and the Fung Shui rocks (Child-given rocks), the
temporarily fenced-off rocks buffer zone and from the edge of Rocks alter is
not required. The fenced-off rocks buffer zone would be implemented when there
are construction activities in vicinity of the cultural heritage.
9.
LANDSCAPE AND VISUAL IMPACT
9
9.1
According to Section 9.3 of the EM&A Manual (AEIAR-173/2013),
landscape and visual mitigation measures during the construction phase shall be
checked to ensure that they are fully realized and implemented on site.
9.2
Site audits were carried out on a weekly basis to monitor and audit the
timely implementation of landscape and visual mitigation measures listed in
“Environmental Mitigation Implementation Schedule (EMIS)” (shown in Appendix
J).
9.3
The implementation of landscape and visual mitigation measures was
checked by a registered landscape architect. No non-compliance of the landscape
and visual impact was recorded in the reporting month. Details of the audit
findings and implementation status are presented in Appendix I.
10.
LANDFILL GAS MONITORING
Monitoring Requirement
10
10.1
In accordance with Section 10.1.1 of the EM&A Manual
(AEIAR-173/2013), monitoring of landfill gas is required for construction works
within the Sai Tso Wan Landfill Consultation Zone during the construction
phase. Since no excavation activity for this Project was carried out within the
Sai Tso Wan Landfill Consultation Zone in the reporting month, no landfill gas
monitoring is required.
11.
HAZARD TO LIFE
11
11.1
According to Section 11.1.1 of EM&A Manual (AEIAR-173/2013), as no
overnight storage of explosive on site is required for the construction of the
Project, the hazard assessment is deemed not necessary. Thus, environmental
monitoring and audit is not required.
12.
ENVIRONEMNTAL AUDIT
Site Audits
12
12.1
Site audits were carried out on a weekly basis to monitor the timely
implementation of proper environmental management practices and mitigation
measures in the Project site. The summaries of site audits are attached in Appendix
I.
12.2
Site audits for each contract were conducted as follows.
·
ED/2018/04 - Site audits were conducted on 06,
13, 20 & 27 August 2026 in the reporting month.
Site inspection of the IEC was conducted on 13 August 2026. No non-compliance was observed
during the site audit.
·
ED/2020/03 - Site audits were conducted on 06,
14, 20 & 27 August 2026 in the reporting month.
Site inspection of the IEC was conducted on 14 August 2026. No non-compliance was observed
during the site audit.
Implementation Status of
Environmental Mitigation Measures
12.3
According to Environmental Permits, the approved EIA Reports (Register
No.: AEIAR-174/2013 and AEIAR-173/2013), and the EM&A Manuals of the
Project (AEIAR-174/2013 and AEIAR-173/2013), the mitigation measures detailed
in the documents are recommended to be implemented during the construction
phase. An Environmental Mitigation Implementation Schedule (EMIS) is provided
in Appendix J.
12.4
The ET weekly site inspections were carried out during the reporting
month and the observations and recommendations are summarized in Table 12.1.
