Measuring Procedures
2.6
The measuring procedures of the 1-hour dust meters were
in accordance with the Manufacturer’s Instruction Manual as follows: (OC-9200
Dust Monitoring System)
l
The 1-hour dust meter is placed at least 1.3 meters
above ground.
l
Set POWER to “ON” and make sure that the battery level
was not flash or in low level.
l
Allow the instrument to stand for about 3 minutes and
then the cap of the air sampling inlet has been released.
l
Push the knob at MEASURE position.
l
Set time/mode setting to [BG] by pushing the time
setting switch. Then, start the background measurement by pushing the
start/stop switch once. It will take 6 sec. to complete the background
measurement.
l
Push the time setting switch to change the time
setting display to [MANUAL] at the bottom left of the liquid crystal
display.
l
Finally, push the start/stop switch to stop the
measuring after 1 hour sampling.
l
Information such as sampling date, time, count value
and site condition were recorded during the monitoring period.
Maintenance/Calibration
2.7
The following maintenance/calibration was required for
the direct dust meters:
l
Check and calibrate the meter by HVS to check the
validity and accuracy of the results measured by direct reading method at
2-month intervals throughout all stages of the air quality monitoring.
2.8
24-hour TSP
Monitoring
Instrumentation
2.9
High volume (HVS) samplers (Model TE-5170), 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). Moreover, the HVS also met all the requirements in section
2.5 of the updated EM&A Manual.
2.10
The positioning of the HVS samplers are as follows:
l
A horizontal platform was provided with appropriate
support to secure the samplers against gusty wind.
l
No two samplers were placed less than 2 meters apart.
l
The distance between the sampler and an obstacle, such
as buildings, was at least twice the height that the obstacle protrudes above
the sampler.
l
A minimum of 2 meters of separation from walls,
parapets and penthouses was required for rooftop samples.
l
A minimum of 2 meters separation from any supporting
structure, measured horizontally was required.
l
No furnaces or incineration flues were nearby.
l
Airflow around the sampler was unrestricted.
l
The sampler was more than 20 meters from the drip
line.
l
Any wire fence and gate, to protect the sampler,
should not cause any obstruction during monitoring.
Operating/analytical procedures for the operation of
HVS
2.11
Operating/analytical procedures for the air quality
monitoring are highlighted as follows:
l
Prior to the commencement of the dust sampling, the flow
rate of the high volume sampler was properly set (between 1.1 m3/min. and 1.4
m3/min.) in accordance with the manufacturer’s instruction to within the range
recommended in USEPA Standard Title 40, CFR Part 50.
l
For TSP sampling, fiberglass filters have a collection
efficiency of > 99% for particles of 0.3μm diameter were used.
l
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.
l
The filter holding frame was then removed by loosening
the four nuts and a weighted and conditioned filter was carefully centred with
the stamped number upwards, on a supporting screen.
l
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.
l
The shelter lid was closed and secured with the
aluminium strip.
l
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 by using the filter number).
l
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.
l
Before weighing, all filters were equilibrated in a
conditioning environment for 24 hours.
l
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 was required for
the HVS:
l
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.
l
High volume samplers were calibrated at bi-monthly
intervals using TE-5025A Calibration Kit through\hout all stages of the air
quality monitoring.

Monitoring Methodology and QA/QC
Procedure
3.6
The procedures for noise monitoring were as follows:
l
The Sound Level Meter was set on a tripod at a height
of 1.2 m above the ground.
l
The battery condition was checked to ensure the
correct functioning of the meter.
l
Parameters such as frequency weighting, the time
weighting and the measurement time were set as follows:
—

: 30 minutes
l
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.
l
The wind speed was frequently checked with the
portable wind meter.
l
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.
l
Noise measurement was paused temporarily during
periods of high intrusive noise if possible and observation was recorded when
intrusive noise was not avoided.
l
Noise monitoring was 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.
Maintenance and Calibration
3.7
The microphone head of the sound level meter and
calibrator were cleaned with a soft cloth at quarterly intervals.
