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.
24-hour TSP
Monitoring
Instrumentation
2.8
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.
2.9
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
2.10
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
2.11 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.
2.12
All 1-hour TSP monitoring was
conducted as scheduled in the reporting month.
2.13
No Action/Limit Level
exceedance of the 1-hour TSP monitoring was recorded.
2.14
All 24-hour TSP monitoring was
conducted as scheduled in the reporting month. The monitoring schedule for the reporting
month is shown in Appendix D.

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:
— frequency weighting :
A
— time weighting :
Fast
— time measurement :
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.
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 shall be
checked using an acoustic calibrator generating a known sound pressure level at
a known frequency. Measurements may be accepted as valid only if the calibration
levels from before and after the noise measurement agree to within 1.0 dB.
