In 2009, Civil Engineering
and Development Department (CEDD) commissioned a Kai Tak
Development (KTD) – Trunk Road T2 and Infrastructure at South Apron
Investigation. The assignment
covers the provision of the Trunk Road T2 and its connections with the Central
Kowloon Route (CKR) at the north apron area and the Tseung Kwan O – Lam Tin
Tunnel (TKOLTT) to the south in the Cha Kwo Ling area.
1.2
The Trunk Road T2
Project is one of the designated Projects under Schedule 2 of the EIAO proposed
in the KTD. CEDD submitted the Project Profile (No. PP-379/2009) on 24 March
2009 for application for an EIA study brief for the Trunk Road T2 Project under
the EIAO. Accordingly, an EIA Study Brief (ESB-203/2009) for the Trunk Road T2
Project was issued on 30 April 2009. The Environmental Impact Assessment (EIA) Report for the Trunk Road T2
Project was approved under the Environmental Impact Assessment Ordinance (EIAO)
on 19 September 2013. The corresponding Environmental Permit (EP) was issued on
19 September 2013 (EP no.: EP-451/2013).
1.3
The Contract No.

AIR Quality
Monitoring Requirement
2.1
According to the EM&A Manual (AEIAR-174/2013), 24-hour Total
Suspended Particulates (TSP) monitoring was conducted to monitor the air
quality for this Project. For regular impact monitoring, a sampling frequency
of at least once in every six days at all of the monitoring stations for
24-hour TSP monitoring. In case of complaints, 1-hour TSP monitoring should be
conducted at least three times in every six days when the highest dust impacts
are likely to occur. Appendix A shows the established Action/Limit
Levels for the environmental monitoring works.
Monitoring Locations
2.2
Five designated monitoring stations were selected for air quality
monitoring programme. Table 2.1 describes the air quality monitoring
locations, which are also depicted in Figure 2.
2.3
The monitoring location at Kai Tak area has been reviewed and updated to
obtain the data with higher representative based on several conditions, such as
distance between monitoring location and the sensitive receiver, non-project
related interference, obstruction to the construction works on site and the
power supply problem. The monitoring location KTD1a and KER1b has been updated
to KTD1 and KER1 respectively, where are the original location as proposed in
the EM&A manual (AEIAR-174/2013). And the monitoring location KTD2c was
remained unchanged after the aforementioned review. Monitoring location KTD2c
was then further relocated to KTD2d after the review of status and location of
monitoring station conducted in between February and March 2021.

High Volume Samplers (HVS) in compliance with the specification
stipulated in the EM&A Manual (AEIAR-174/2013), Section 2.2.1.4, were used
to carry out 24-hour TSP monitoring. Direct reading dust meter were also used
to measure 1-hour average TSP levels. The 1-hour sampling was determined by HVS
to check the validity and accuracy of the results measured by direct reading
method.
2.6
Wind data monitoring equipment was set at rooftop (about 41/F) of Yau
Lai Estate Bik Lai House, Lam Tin for logging wind speed and wind direction
such that the wind sensors were clear of obstructions or turbulence caused by
building. The wind data monitoring equipment was re-calibrated at least once
every six months and the wind directions were divided into 16 sectors of 22.5
degrees each. Wind data is attached in Appendix D.

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
2.12
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-174/2013).
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
centered 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 (High Precision Chemical Testing 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
2.13
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 were 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.

Monitoring
Methodology and QA/QC Procedure
3.6
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
3.7
The microphone head of the sound level meter and calibrator were cleaned
with a soft cloth at quarterly intervals.
3.8
The sound level meter and calibrator were checked and calibrated at
yearly intervals.
3.9
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
