ENVIRONMENTAL MONITORING REQUIREMENTS
Construction Dust and Noise Monitoring Location
The monitoring station
for construction dust and noise monitoring pertinent to the Project has been
identified based on the approved EM&A Manual for the Project. The location
of the construction dust and noise monitoring station is summarized in Table 2.1 and displayed in Figure 2.

Notes:
1. The dust and noise monitoring station
proposed in the EM&A Manual (i.e. Ko Fai House, Kwun Fai Court with ID: M-A6/
M-N6) 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 coordinates of SKH Tsoi
Kung Po Secondary School can be represented as follow:
Latitude: 22.314719, Longitude: 114.180694
(HK80 Geographical Coordinates)
Monitoring Requirement
In accordance with the
approved EM&A Manual, 1-hour and 24-hour Total Suspended Particulates (TSP)
levels should be measured at the designated air quality monitoring stations to
indicate the impacts of construction dust on air quality. Regular Impact 24-hour
TSP monitoring should be carried out for at least once every 6 days, and 1-hour
TSP monitoring should be done at least 3 times every 6 days when the highest
dust impact occurs.
Monitoring Equipment
24-hour
TSP air quality monitoring was performed using High Volume Sampler (HVS)
deployed at the designated monitoring station. The HVS shall meet all the
requirements of the EM&A Manual.
A
portable direct reading dust meter was used to carry out the 1-hour TSP
monitoring.
The
model of the dust monitoring equipment used is summarized in Table 2.2.

*Notes:

27th May 2020 for1- hour TSP monitoring.
Monitoring Methodology for HVS
The
following guidelines were adopted during the installation of 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.
Prior
to the commencement of the dust sampling, the flow rate of the high volume
sampler shall be properly set. The power supply should be checked to ensure the
proper functioning of the sampler. The sampler is recommended to be operated
for 5 minutes to establish thermal equilibrium before placing any filter media
at the designated air monitoring station.
The
filter holding frame should be removed by loosening the four nuts and placing
carefully a weighted and conditioned filter at the centre with the stamped
number upwards on a supporting screen.
The
filter should be aligned on the screen so that the gasket formed an airtight
seal on the outer edges of the filter. The filter holding frame should be
tightened to the filter holder with swing bolts. The applied pressure should be
sufficient to avoid air leakage at the edges.
A
programmed timer should be used to control the duration of operation.
Information should be recorded on the record sheet, which included the starting
time, the weather condition and the filter number.
After
sampling process is finished, the filter should be removed and sent to the
laboratory for weighting. The elapsed time should also be recorded.
All
filters should be equilibrated in a conditioning environment for 24 hours
before weighting. The conditioning environment temperature should be between
25¢XC and 30¢XC and not vary by more than ¡Ó3¢XC;
the relative humidity (RH) should be <50% and not vary by more than ¡Ó5%.
A convenient working RH is 40%.
Maintenance and Calibration for HVS
The
high volume motors and their accessories should be properly maintained,
including routine motor brushes replacement and electrical wiring checking, to
ensure that the equipment and a continuous power supply were in good working
condition.
Initial
calibration of dust monitoring equipment shall be conducted upon installation
and thereafter at fortnightly intervals. The transfer standard shall be
traceable to the internationally recognized primary standard and be calibrated
annually. The calibration certificate for the HVS is provided in Appendix C.
Monitoring Methodology for Direct Reading Dust Meter
Portable
Laser Particle Photometer Monitors should be operated in accordance with the
Manufacturer¡¦s instruction Manual as below:
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
Maintenance and Calibration for Direct Reading Dust Meter
ET
shall submit sufficient information to the IEC to prove that the instrument is
capable of achieving comparable results to the HVS. The instrument should also
be calibrated regularly, and the 1-hour sampling shall be determined
periodically by the HVS to check the validity and accuracy of the results
measured by direct reading method. The calibration certificate for the direct
reading dust meter is provided in Appendix C.
Monitoring Requirement
In
accordance with the EM&A Manual, impact noise monitoring should be conducted
at the designated noise monitoring stations for at least once a week during the
construction phase of the Project. The parameters, frequency and duration of
impact noise monitoring is summarized in Table 2.3.

Monitoring Equipment
Noise
monitoring was performed using sound level meter at the designated monitoring
station. The sound level meters deployed comply with the International Electrotechnical Commission Publications 651:1979 (Type 1)
and 804:1985 (Type 1) specifications. Acoustic calibrator was deployed to check
the sound level meters at a known sound pressure level.
The
model of the noise monitoring equipment used is summarized in Table 2.4.

Monitoring Methodology
Noise
measurement should be conducted as the following procedures:
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: continuous 5 minutes interval
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
Maintenance
and calibration procedures should also be carried out, including:
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.
Construction Dust and Noise Monitoring Schedule
The
environmental monitoring schedule for the reporting period is provided in Appendix E.
The
Action and Limit Levels for construction dust and noise monitoring are provided
in Appendix
