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.

4.2.2
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 quality monitoring station with its location as shown in Figure

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 schedule for environmental monitoring for the reporting
month is provided in Appendix D.
