Notes:
1. The dust and noise monitoring
stations proposed in the EM&A Manual for M-A6/ M-N6 (i.e. Ko Fai House, Kwun Fai Court) was
not available for impact dust and noise monitoring, therefore impact monitoring
was conducted at M-A3/ M-N3 as an alternative which was agreed by the ER, IEC
and EPD;
2. The noise monitoring station proposed
in the EM&A Manual for E-N12 (i.e. Grand Waterfront Tower 3) was not
available for impact dust and noise monitoring, therefore impact monitoring was
conducted at E-N12a as an alternative which was agreed by the ER, IEC and EPD;
3. The dust and noise monitoring
stations proposed in the EM&A Manual for E-A14 (i.e. Wyler Gardens) and E-N21 (i.e Hang Chien Court Block J) was
not available for impact dust and noise monitoring, therefore impact monitoring
was conducted at E-A14a/ E-N21a as an alternative which was agreed by the ER,
IEC and EPD;
4. The dust monitoring stations
proposed in the EM&A Manual for W-A5 (i.e. The Coronation) was not
available for impact dust monitoring, therefore impact monitoring was conducted
at W-A6 as an alternative which was agreed by the ER, IEC and EPD.

Monitoring Methodology
for HVS
¡P
Sufficient support is provided to secure the samplers against gusty
wind.
¡P
No two samplers are placed less than 2 meters apart.
¡P
The distance between the sampler and an obstacle, such as
buildings, is at least twice the height that the obstacle protrudes above the
sampler.
¡P
A minimum of 2 meters of separation from walls, parapets and
penthouses is required for rooftop samples.
¡P
A minimum of 2 meters separation from any supporting structure,
measured horizontally is required.
¡P
No furnaces or incineration flues are nearby.
¡P
Airflow around the samplers is unrestricted.
¡P
The samplers are more than 20 meters from the drip line.
¡P
Any wire fence and gate, to protect the sampler, should not cause
any obstruction during monitoring.
¡P
Permission must be obtained to set up the samplers and to obtain
access to the monitoring stations.
¡P
A secured supply of electricity is needed to operate the samplers.
Maintenance
and Calibration for HVS
Monitoring Methodology
for Direct Reading Dust Meter
a) Pulling up
the air sampling inlet cover
b) Changing the
Mode 0 to BG
c) Pressing
Start/Stop switch
d) Turning the
knob to SENSI.ADJ and press it
e) Pressing

Monitoring Methodology
a) Free field
measurements was made at monitoring location M-N3. A correction of +3 dB(A) shall be made to the free field measurements.
b) The battery
condition should be checked to ensure good functioning of the meter.
c) Parameters
such as frequency weighting, the time weighting and the measurement time should
set as follow:
(i) Frequency
weighting: A
(ii) Time weighting: Fast
(iii) Measurement time: 30 minutes
d) Prior to and
after noise measurement, the meter shall be calibrated using the calibrator for
94.0 dB at 1000 Hz. If the difference in the calibration level before and after
measurement is more than 1.0 dB, the measurement will be considered invalid and
repeat of noise measurement is required after re-calibration or repair of the
equipment.
e) The wind
speed at the monitoring station shall be checked with the portable wind meter.
Noise monitoring should be 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.
f) Noise
measurement should be paused during periods of high intrusive noise if possible
and observation shall be recorded when intrusive noise is not avoided.
g) At the end
of the monitoring period, the Leq, L10 and L90 should
be recorded. In addition, site conditions and noise sources should also be
recorded on a standard record sheet.
Maintenance
and Calibration
a) The microphone head of the sound
level meter and calibrator should be cleaned with a soft cloth at quarterly
intervals.
b) The sound level meter and
calibrator should be calibrated annually by a HOKLAS laboratory or the
manufacturer.
The
calibration certificates for noise monitoring equipment are provided in Appendix
D.
