(b.)
A sheath air system to isolate the aerosol in
the chamber to keep the optics clean for maximum reliability; and
(c.)
A built-in data logger compatible with
Windows based program to facilitate data collection, analysis and reporting.
3.6.2
The 1-hour TSP meter is used within the valid
period as follow manufacturer’s Operation and Service Manual.
24-hour TSP
Monitoring
3.6.3
The equipment used for 24-hour TSP
measurement is Tisch Environmental, Inc. Model TE-5170 TSP
high volume air sampling system, which complied with EPA Code of Federal Regulation, Appendix B to Part 50. The High Volume
Air Sampler (HVS) consists of the following:
(a.)
An anodized aluminum shelter;
(b.)
A 8”x10” stainless steel filter holder;
(c.)
A blower motor assembly;
(d.)
A continuous flow/pressure recorder;
(e.)
A motor speed-voltage control/elapsed time
indicator;
(f.)
A 7-day mechanical timer, and
(g.)
A power supply of 220v/50 Hz
3.6.4
The HVS is operated and calibrated on a
regular basis in accordance with the manufacturer’s instruction using Tisch Calibration Kit Model TE-5025A. Calibration would carry out in two month
interval.
3.6.5
24-hour TSP is collected by the ET on filters
of HVS and quantified by a local HOKLAS accredited laboratory, ALS Technichem (HK) Pty Ltd (ALS), upon receipt of the
samples. The ET keep all the
sampled 24-hour TSP filters in normal air conditioned room conditions, i.e. 70%
RH (Relative Humidity) and 25oC, for six months prior to disposal.
Noise Monitoring
3.6.6
Noise measurements were taken in terms of the
A-weighted equivalent sound pressure level (Leq)
measured in decibels dB(A). Supplementary statistical results
(L10 and L90) were also obtained for reference.
3.6.7
During the monitoring, all noise measurements
would be performed with the meter set to FAST response and on the A-weighted
equivalent continuous sound pressure level (Leq). Leq(30min)
in six consecutive Leq(5min) measurements
will use as the monitoring parameter for the time period between 0700-1900
hours on weekdays; Leq(5min) measurements
would be used as monitoring parameter for other time periods (e.g. during
restricted hours), if necessary.
3.6.8
Prior of noise measurement, the accuracy of
the sound level meter is checked using an acoustic calibrator generating a
known sound pressure level at a known frequency. The checking is performed before and
after the noise measurement.
Water
Quality
3.6.9
Water quality monitoring is conducted at the
designated or alternative locations. The sampling procedures with the in-situ
monitoring are presented as below:
Sampling Procedure
3.6.10
A Digital Global
Positioning System (GPS) is used to identify the designated monitoring stations
prior to water sampling. A
portable, battery-operated echo sounder or tape measurement is used for the
determination of water depth at each station. At each station, water sample would be
collected from 0.1m below water surface or the water surface to prevent the
river bed sediment for stirring.
3.6.11
If the water level of a
monitoring station is too shallow when sampling, sediment would be disturbed
which affecting the accuracy of water quality monitoring. In order to avoid disturbing sediment,
depth limits should be set up for the water sampling for the ease of
reference. When the measured water
depth of the monitoring station (both control and impact stations) is lower
than 150mm, water monitoring would not be to perform at that monitoring
location. Instead, the monitoring
location will be moved to a temporary alternative location monitoring location
based on the criteria below:-
(a) the alternative location should be either
upstream or downstream of the original location and at the same the
river/drain channel
(b) the alternative location should be within 15m far from the original location
(c) if no suitable alternative location could be
found within 15m far from the original
location, the sampling at that location will be cancelled since sampling at too
far from the designated location could not make a representative sample.
3.6.12
The sample container will be rinsed with a
portion of the water sample. The
water sample then will be transferred to the high-density polythene bottles as provided by the laboratory,
labeled with a unique sample number and sealed with a screw cap.
3.6.13
Before sampling, general information such as
the date and time of sampling, weather condition as well as the personnel
responsible for the monitoring would be recorded on the field data sheet.
3.6.14
A ‘Willow’ 33-liter plastic cool box packed
with ice will be used to preserve the water samples prior to arrival at the
laboratory for chemical determination.
The water temperature of the cool box is maintained at a temperature as
close to 40C as possible without being frozen. Samples collected are delivered to the
laboratory upon collection.
In-situ Measurement
3.6.15
YSI Professional DSS is used for water
in-situ measures, which automates the measurements and data logging of
temperature, dissolved oxygen and dissolved oxygen saturation.
3.6.16
YSI Professional DSS is used for in-situ pH
measurement. The pH meter is
capable of measuring pH in the range of 0 – 14 and readable to 0.1.
3.6.17
YSI Professional DSS is used for in-situ
turbidity measurement. The turbidity meter is capable of measuring turbidity in
the range of 0 – 1000 NTU.
3.6.18
All in-situ measurement equipment are
calibrated by HOKLAS accredited laboratory of three month interval.
Laboratory Analysis
3.6.19
All water samples analyzed Suspended Solids
(SS) will be carried out by a local HOKLAS-accredited testing laboratory (ALS Technichem (HK) Pty Ltd HOKLAS registration no. 66). SS determination using APHA
Standard Methods 2540D as specified in the EM&A Manual will start within
48 hours of water sample receipt.
3.7.1
Calibration of the HVS is performed upon
installation and thereafter at bimonthly intervals in accordance with the
manufacturer’s instruction using the certified standard calibrator (TISCH Model
TE-5025A).
Moreover, the Calibration Kit would be calibrated annually. The calibration data are properly
documented and the records are maintained by ET for future reference.
3.7.2
The 1-hour TSP meter
was calibrated by the supplier prior to purchase. Zero response of the equipment would be
checked before and after each monitoring event. Annually calibration with the High
Volume Sampler (HVS) in same condition would be undertaken by the Laboratory.
3.7.3
The sound level
meter and calibrator are calibrated and certified by a laboratory accredited
under HOKLAS or any other international accreditation scheme at yearly basis.
3.7.4
All water quality monitoring equipment would
be calibrated by HOKLAS accredited laboratory of three month intervals.
3.7.5
The calibration
certificates of all monitoring equipment used for the impact monitoring program
in the Reporting Period and the HOKLAS accredited certificate of laboratory are attached in Appendix F.
3.8.1
The baseline results form the basis for
determining the environmental acceptance criteria for the impact
monitoring. According to the
approved Environmental Monitoring and Audit Manual, the air quality, construction
noise and water quality criteria were set up, namely Action and Limit levels
are listed in Tables 3-8, 3-9 and 3-10.

4.2.2
As shown in Tables 4-1 to 4-6, all
the 1-hour and 24-hour TSP
monitoring results were below the Action/Limit Levels. No Notification of Exceedance (NOE) was
issued in this Reporting Period.
4.2.3
The meteorological data during the impact
monitoring days are summarized in Appendix K.
5.1.1
Proposal for partial
termination of the construction phase EM&A programme
for Contract 2, Contract 4, Contract 7 and
Contract SS C505 was approved by EPD on 9 July 2020 (EPD’s ref.: ( ) in Ax (3)
to EP 2/N7/A/52 Pt.17). The Partial termination proposal for Contract 3 was
approved by EPD on 4 May 2021 (EPD’s ref.: ( ) in Ax (3) to EP 2/N7/A/52 Pt.18). The corresponding noise quality monitoring
stations NM1, NM7, NM8, NM9 and NM10 ceased accordingly, while monitoring at other
monitoring stations continued in the Reporting Period.
5.1.2
The noise monitoring schedule is presented in
Appendix
H and the monitoring results are summarized in the following
sub-sections.
5.2.1
In the Reporting Period, a total of 20 events noise measurements were carried out at the
designated locations. The sound
level meter was set in 1m from the exterior of the building façade including
noise monitoring locations NM3, NM4, NM5, and NM6. Therefore, no façade correction (+3 dB(A)) is added according to acoustical principles and EPD
guidelines. However, free-field
status were performed at NM2a and façade correction (+3 dB(A))
has added according to the requirement in this month. The noise monitoring results at the
designated locations are summarized in Tables 5-1 and 5-2. The detailed noise monitoring
data are presented in Appendix I and the relevant
graphical plots are shown in Appendix J.
