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 Start/Stop switch again
f) Returning the knob to the position MEASURE slowly
g) Pressing the timer set switch to set measuring time
h) Removing the cap and start the measurement

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.
