Noise Monitoring
Parameters, Frequency and Duration
4.1.2.
Noise monitoring shall be carried out at all the designated monitoring
stations. The monitoring frequency shall depend on the scale of the
construction activities. The following is an initial guide on the regular
monitoring frequency for each station on a weekly basis when noise generating
activities are underway:
·
One set of measurements between 0700-1900 hours on
normal weekdays (six consecutive Leq/5min readings);
·
One set of measurements between 1900-2300 hours;
·
One set of measurements between 2300-0700 hours of
next day; and
·
One set of measurements between 0700-2300 hours on
holidays (three consecutive Leq/5min readings).
4.1.3.
For the latter 3 sets of measurements specified in Section 4.1.2 above,
one set of measurements shall at least include 3 consecutive Leq (5min)
results.
4.1.4.
Supplementary information for data auditing, statistical results such as
L10 and L90 shall also be obtained for reference.
4.1.5.
If a school exists near the construction activity, noise monitoring
shall be carried out at the monitoring stations for the schools during the
examination periods. The ET leader shall liaise with the school’s personnel and
the examination authority to ascertain the exact dates and times of all
examination periods during the course of the contract.
Monitoring Equipment
4.1.6.
Noise monitoring was performed
using sound level meter at the
designated monitoring locations.
The sound level meters shall comply with the
International Electrotechnical Commission
Publications 651:1979
(Type
1) and
804:1985 (Type 1)
specifications.
Acoustic calibrator shall
be deployed to check the sound level meters at a known sound pressure level. Brand and model of the equipment is given in Table
4.2.

4.1.7. The calibration certificates of the noise monitoring
equipment are attached in Appendix 4.2.
Sampling Procedure and
Monitoring Equipment
4.1.8.
Monitoring Procedure
(a)
The monitoring station shall normally
be at a point 1m from the exterior of the sensitive receiver’s building façade
and be at a position 1.2m above the ground.
(b)
Façade measurements were made at the
monitoring locations. For free-field measurement, a correction factor of +3 dB (A)
would be applied.
(c)
The battery condition was checked to
ensure the correct functioning of the meter.
(d)
Parameters such as frequency weighting,
the time weighting and the measurement time were set as follows:
(e)
Frequency weighting: A, Time weighting:
Fast, Measurement time set: continuous 5 mins
(f)
Prior and after to the noise
measurement, the meter was checked 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.
(g)
Noise measurements shall not be made in
fog, rain, wind with a steady speed exceeding 5m/s or wind with gusts exceeding
10m/s. The wind speed shall be checked with a portable wind speed meter capable
of measuring the wind speed in m/s.
4.1.9.
Maintenance and Calibration
(a)
The microphone head of the sound level
meter was cleaned with soft cloth at regular intervals.
(b)
The sound level meter and calibrator
were calibrated at yearly intervals.
EVENT and action plan
4.1.10. Noise Standards for Daytime Construction Activities are
specified under EIAO-TM. The Action and Limit levels for construction noise are
defined in Table 4.3 and Appendix 4.1. Should non-compliance of the
criteria occurs, action in accordance with the Event and Action Plan in Appendix 6.1
shall be carried out.

Remark 2: Construction noise during restricted hours is under the
control of Noise Control Ordinance Limit Level to be selected based on Area
Sensitivity Rating.
Remark 3: Limit Level for restricted hour monitoring shall act as
reference level only. Investigation would be conducted on CNP compliance if
exceedance recorded during restricted hour noise monitoring period.

Water Quality Parameters,
Frequency and Duration
4.3.2.
The levels of dissolved oxygen (DO), turbidity and pH shall be measured
in situ while suspended solids (SS) is determined by laboratory analysis at all
the designated monitoring stations.
4.3.3.
In association with the water quality parameters, other relevant data
shall also be recorded, such as monitoring location / position, time, water
temperature, salinity, DO saturation, weather conditions, and any special
phenomena underway near the monitoring station.
4.3.4.
The sampling frequency of at least three days per week should be
undertaken when the highest dust impact occurs. Upon completion of the
construction works, the monitoring exercise at the designated monitoring
locations should be continued for four weeks in the same manner as the impact
monitoring.
4.3.5.
The interval between two sets of monitoring should not be less than 36
hours except where there are exceedances of Action and/or Limit Levels, in
which case the monitoring frequency will be increased.
4.3.6.
Replicate in-situ measurements should be carried out in each sampling
event.
Sampling Procedures and
Monitoring Equipment
Dissolved Oxygen and Temperature Measuring
Equipment
4.3.7.

Sample would be taken using bucket
sampler at surface level.
(e)
Transfer the sampled water carefully
into cleaned water bottles (2x 1000ml) provided by the laboratory at the spot
after the collection of the water sample for the subsequent laboratory
Suspended Solid testing.
(f)
Transfer the sampled water from the
bucket sampler to the rinsed water container for in-situ measurement (In case
of the in-situ measurement cannot be carried at spot due to safety and adverse
weather condition, sampled water from the bucket sampler will be transfer to
cleaned water bottles provided by laboratory. Then, In-situ measurement will be
conducted at a safe location which sampled water inside cleaned water bottle
will be transfer to the rinsed water container for in-situ measurement) In-situ
measurement shall be measured in duplicate.
(g)
Parameters including Water Temperature (°C),
pH (units), Salinity (ppt), DO (mg/L), DO saturation (%) will be measured by
the Multifunctional Meter and Turbidity (NTU) will be measured by turbid meter.
(Water Temperature and Salinity will be measured as reference parameters)
(h)
Record the result on the data log sheet
and record any special finding during / after in-situ measurement.
(i)
The water sample bottles will be stored
in a cool box (at cooled to 4℃ without being frozen), which shall be delivered
to HOKLAS laboratory (ALS Technichem (HK) Pty Ltd) for further testing to
determine the level of SS.
4.3.14.
Maintenance and Calibration
(a)
The responses of sensors and electrodes
of the water quality monitoring equipment were cleaned and checked at regular

* Remarks:
The value of 1.0mg/L was taken as
the value for measurement with suspended solid level of <1.0mg/L for Action
and Limit level calculation.
It is recommended that upstream
monitoring station (monitoring station E, AC1, AC2, AC3 and H) would be taken
as control reference for exceedance investigation only. Action and limit level
would not be establish using the baseline data.
If the SS and Turbidity recorded from the Control
Stations (E, H, AC1, AC2, AC3) are higher than the Impact Stations (I and F) on the same day of measurement, 120% and 130% of the Control Stations' results would be referenced as the Action and Limit Levels.

To
minimize the dust impact to the surrounding ASRs, dust suppression measures
stipulated in the Air Pollution Control (Construction Dust) Regulation should
be incorporated to control dust emission from the site; ·
To
reduce the noise impacts at the affected NSRs during normal daytime working
hours, mitigation measures such as adopting quiet PME and construction noise
barriers are recommended. · To alleviate the construction noise impact on the
affected NSRs, construction noise barriers or enclosures would be erected to
provide screening from the construction plant. · Surface run-off from construction sites should be
discharged into storm drains via adequately designed sand/silt removal
facilities such as sand traps, silt traps and sedimentation basins. · Silt removal facilities, channels and manholes
should be maintained and the deposited silt and grit should be removed
regularly, at the onset of and after each rainstorm to prevent local flooding. |
