2.1.1
Tolo Highway and Fanling Highway are expressways
in the North East New Territories connecting Sha Tin,
Tai Po and Fanling. These highways form a vital part of the
strategic Route 1, which links Hong Kong Island to Shenzhen. At present, this section of Route 1 is a
dual 3-lane carriageway. However,
at several major interchanges along this section of Route 1, the highway is
only dual-2 lane. Severe congestion
is a frequent occurrence during peak periods, particularly in the Kowloon bound
direction.
2.1.2
The
objective of the Widening of Tolo Highway / Fanling Highway between Island House Interchange and Fanling is to widen Tolo Highway
and Fanling Highway to dual 4-lane carriageway in
order to alleviate the current traffic congestion problems and to cope with the
increasing transport demands to and from the urban areas and also cross

4.1.1
In
accordance with the Updated EM&A Manual, 1-hr and 24-hr total suspended particulate
(TSP) levels at the designated air quality monitoring station are required. Impact 24-hour TSP monitoring should be
carried out for at least once every 6 days. For the 1-hr TSP impact monitoring, the
sampling frequency of at least three times in every 6 days should be undertaken
when the highest dust impact occurs.
4.2.1
The
1hr- TSP and 24-hr TSP air quality monitoring were performed using a High
Volume Sampler (HVS), of which its location and operation satisfy, as far as
practicable, all the requirements as specified in the Updated EM&A Manual. The brand and model of the equipment are
given in Table 4.1.

The
HVS and its accessories were maintained in good working condition, such as
replacing motor brushes routinely and checking electrical wiring to ensure a
continuous power supply.
4.2.3
Calibration
of the HVS (five point calibration) using Calibration Kit was carried out every
two months. The HVS calibration
orifice will be calibrated annually.
Calibration certificate of the TE-5025A Calibration Kit and the HVS are
provided in Appendix C.
4.3.1
Air
quality monitoring was conducted at the location specified in the Updated
EM&A Manual. Table 4.2 describes the details of the air

4.5.1
With
the consideration of criteria stated in the Updated EM&A Manual, the HVS
was installed in the vicinity of the air sensitive receivers.
4.5.2
The
relevant data including temperature, pressure, weather conditions, elapsed-time
meter reading for the start and stop of the sampler, identification and weight
of the filter paper, and any special phenomena observed were recorded. The weather information was referenced
from Hong Kong Observatory (http://www.weather.gov.hk/wxinfo/pastwx/extractc.htm).
4.5.3
A
HOKLAS accredited laboratory with constant temperature and humidity control,
and equipped with necessary measuring and conditioning instruments, to handle
the 24-hr TSP samples, was employed for sample analysis.
4.5.4
Filter
papers of size 8"x10" were labelled before sampling. They were inspected to be clean with no
pin holes and conditioned in a humidity controlled chamber for over 24-hr and
were pre-weighed before use for the sampling.
4.5.5
The
24-hr TSP levels were measured by following the standard high volume sampling
method for TSP as set out in the Title 40 of the United States Code of Federal
Regulations, Chapter 1 (Part 50), Appendix B. TSP was sampled by drawing air through a
conditioned, pre-weighted filter paper inside the HVS at a controlled air flow
rate. After 24-hr sampling, the
filter papers loaded with dust were kept in a clean and tightly sealed plastic
bag, and then returned to the laboratory for reconditioning in the humidity
controlled chamber followed by accurate weighing by an electronic balance with
a readout down to 0.1 mg.
4.5.6
All
the collected samples were kept in a good condition for 6 months before
disposal.
4.5.7
For
1-hr TSP monitoring, monitoring methodology is the same as 24-hr TSP monitoring
which has been presented in Section 4.5.1 to Section 4.5.6, but with sampling period changed
to 1 hour.
4.6.1
The

¡P
Time measurement: Leq(30-minutes)
during non-restricted hours i.e. 07:00 ¡V 19:00 hrs on
normal weekdays
¡P
Prior to and after each noise measurement, the
meter was calibrated using the acoustic calibrator for 94dB(A)
at 1000 Hz. If the difference in
the calibration level before and after measurement was more than 1dB(A), the measurement would be considered invalid and
repeat of noise measurement would be required after re-calibration or repair of
the equipment.
¡P
At the end of the monitoring period, the Leq, L10 and L90 were recorded. In addition, site conditions and noise
sources were recorded on a standard record sheet.
¡P
A façade correction of +3dB (A) shall be made to
the noise parameter obtained by free field measurement.
