[1] The air monitoring station proposed in the
EM&A Manual (i.e. Wyler Gardens with ID: E-A14) was not available for
impact dust monitoring, therefore impact monitoring was conducted at E-A14a as
an alternative which was agreed by the ER, IEC and EPD.
Monitoring
Methodology
(a)
The HVS was
installed in the vicinity of the air sensitive receivers. The following criteria were considered in the
installation of the
HVS as far as practicable:-
(i)
A horizontal platform with
appropriate support to secure the sampler against gusty wind was provided.
(ii)
Two samplers should
not be placed less than 2m apart from each other;
(iii)
The distance between the HVS and
any obstacles, such as buildings, was at least twice the height that the
obstacle protrudes above the HVS.
(iv)
A minimum of 2 meters separation
from walls, parapets and penthouse for rooftop sampler.
(v)
A minimum of 2 meters separation
from any supporting structure, measured horizontally is required.
(vi)
No furnace or incinerator flues
nearby.
(vii)
Airflow around the sampler was
unrestricted.
(viii)
The sampler was located more than
20 meters from any dripline.
(ix)
Any wire fence and gate, required
to protect the sampler, did not obstruct the monitoring process.
(x)
Permission was obtained to set up
the samplers and access to the monitoring station.
(xi)
A secured supply of electricity
was obtained to operate the sampler.
(b)
Preparation of
Filter Papers
(i)
Glass fibre filters, G810 were
labelled and sufficient filters that were clean and without pinholes were
selected.
(ii)
All filters were equilibrated in
the conditioning environment for 24 hours before weighing. The conditioning
environment temperature was around 25 °C and not variable by more than ±3 °C;
the relative humidity (RH) was < 50% and not variable by more than ±5%. A
convenient working RH was 40%.
(iii)
All filter papers were prepared
and analysed by ALS Technichem (HK) Pty
Ltd., which is a HOKLAS accredited laboratory and has
comprehensive quality assurance and quality control programmes.
(c)
Field
Monitoring
(i)
The power supply was checked to ensure the HVS works properly.
(ii)
The filter holder and the area
surrounding the filter were cleaned.
(iii)
The filter holder was removed by
loosening the four bolts and a new filter, with stamped number upward, on a
supporting screen was aligned carefully.
(iv)
The filter was properly aligned
on the screen so that the gasket formed an airtight seal on the outer edges of
the filter.
(v)
The swing bolts were fastened to
hold the filter holder down to the frame. The pressure applied was sufficient to avoid
air leakage at the edges.
(vi)
Then the shelter lid was closed
and was secured with the aluminium strip.
(vii)
The HVS was warmed-up for about 5
minutes to establish run-temperature conditions.
(viii)
A new flow rate record sheet was
set into the flow recorder.
(ix)
On site temperature and
atmospheric pressure readings were taken and the flow rate of the HVS was
checked and adjusted at around 1.3 m3/min, and complied with the
range specified in the EM&A Manual (i.e. 0.6-1.7 m3/min).
(x)
The programmable digital timer
was set for a sampling period of 24 hrs, and the starting time, weather
condition and the filter number were recorded.
(xi)
The initial elapsed time was
recorded.
(xii)
At the end of sampling, on site
temperature and atmospheric pressure readings were taken and the final flow
rate of the HVS was checked and recorded.
(xiii)
The final elapsed time was
recorded.
(xiv)
The sampled filter was removed
carefully and folded in half length so that only surfaces with collected
particulate matter were in contact.
(xv)
It was then placed in a clean
envelope and sealed.
(xvi)
All monitoring information was
recorded on a standard data sheet.
(xvii) Filters were then sent to ALS Technichem
(HK) Pty Ltd. for analysis.
(d)
Maintenance and
Calibration
(i)
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.
(ii)
HVSs were calibrated using
TE-5025A Calibration Kit upon installation and thereafter at bi-monthly
intervals.
(iii)
Calibration certificate of the TE-5025A Calibration Kit and the HVSs are provided in Appendix E.
(a)
Measuring Procedures
The measuring procedures of the 1-hour dust
meter are in accordance with the Manufacturer’s Instruction Manual as follows:
(i)
Turn the power on.
(ii)
Close the air collecting opening cover.
(iii)
Push the “TIME SETTING” switch to [BG]
(iv)
Push “START/STOP”
switch to perform background measurement for 6 seconds.
(v)
Turn the knob at SENSI ADJ position to insert
the light scattering plate.
(vi)
Leave the equipment for 1 minute upon “SPAN
CHECK” is indicated in the display.
(vii)
Push “START/STOP” switch to perform automatic
sensitivity adjustment. This measurement takes 1 minute.
(viii)
Pull out the knob and return it to MEASURE
position.
(ix)
Push the “TIME SETTING” switch the time set
in the display to 3 hours.
(x)
Lower down the air collection opening cover.
(xi)
Push “START/STOP” switch to start
measurement.
(b)
Maintenance and Calibration
(i)
The 1-hour TSP meter was
calibrated at 1-year intervals against a continuous particulate TEOM Monitor,
Series 1400ab. Calibration certificates of the Laser Dust Monitors are provided in Appendix E.

Notes:
[1] The noise monitoring stations proposed in the EM&A Manual (i.e.
Grand Waterfront Tower 3 with ID: E-N12 and Hang Chien Court Block J with ID:
E-N21) were not available for impact noise monitoring, therefore impact
monitoring was conducted at E-N12a and E-N21a as an alternative which was
agreed by the ER, IEC and EPD.
[2] A correction of +3 dB(A)
was made to the free field measurements.

Monitoring Methodology
(a)
The sound level meter was set on
a tripod at a height of 1.2 m above the ground.
(b)
Façade measurement was made at E-N12a.
(c)
Free field measurements was made
at monitoring location E-N21a. A correction of +3 dB(A) shall be made to the
free field measurements.
(d)
The battery condition was checked to ensure the correct
functioning of the meter.
(e)
Parameters such as frequency
weighting, the time weighting and the measurement time were set as follows:
(i)
frequency weighting: A
(ii)
time weighting: Fast
(iii)
time measurement: Leq(30-minutes)
during non-restricted hours i.e. 0700 – 1900 on normal weekdays.
(f)
Prior to and after each noise
measurement, the meter was calibrated using the acoustic calibrator for 94
dB(A) at 1000 Hz. If the difference in
the calibration level before and after measurement was more than 1 dB(A), the
measurement would be considered invalid and repeat of noise measurement would
be required after re-calibration or repair of the equipment.
(g)
During the monitoring period, the
Leq, L10 and L90 were recorded. In addition, site conditions and noise
sources were recorded on a standard record sheet.
(h)
Noise measurement was paused
during periods of high intrusive noise (e.g. dog barking, helicopter noise) if
possible. Observations were recorded when intrusive noise was unavoidable.
(i)
Noise monitoring was cancelled in
the presence of fog, rain, wind with a steady speed exceeding 5m/s, or wind
with gusts exceeding 10m/s.
(a)
The microphone
head of the sound level meter was cleaned with soft cloth at
regular intervals.
(b)
The meter and
calibrator were sent to the supplier or HOKLAS laboratory to check and
calibrate at yearly intervals.
(c)
Calibration
certificates of the sound level meters and acoustic calibrators are provided
in Appendix E.
