2.5.1 Monitoring
Procedure
(a)
Façade measurements were made at all monitoring
locations.
(b)
The battery condition was checked to ensure the
correct functioning of the meter.
(c)
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. 07:00 – 1900 on normal weekdays; Leq(5-minutes)
during restricted hours i.e. 19:00
– 23:00 and 23:00 – 07:00 of normal weekdays, whole day of Sundays and Public
Holidays
(d)
Prior to and after each noise measurement, the
meter was calibrated using the acoustic calibrator for 94dB(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.
(e)
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.
(f)
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.
(g)
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.
2.5.2 Maintenance
and Calibration
(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.

4.3.1 The
setting up of the biopiling facility is in progress. Excavated soil from zones
A2, R1, R2, R4, T32E and T35C have been transferred to the facility for later
biopiling treatment. The cement solidification and stabilization facility is in
operation. In February, excavated soil from zones T36A and R8 have undergone
cement solidification and stabilization and samples of the treated soil were
collected for Toxicity Characteristic Leaching Procedure (TCLP) and Unconfined
Compressive Strength (UCS) tests to verify if the treatment standard is
achieved. The TCLP and UCS test results for the samples collected from zones A1
and R5 in January 2014 were received and summarized in Table 4.3. It indicates
that the cement treated soil comply with the relevant standards. The test
results for the samples collected in February were yet to be received and will
be included in next monthly report.
