by EPD on 7 April 2017. Besides, in view
of Location AM1b was demolished and returned to the landlord on 27 April 2018, alterative location AM1c was proposed by
ET and approved by EPD on 26 November 2018. Table
3-2, Table 3-3 and Table 3-4 are respectively listed
the air quality, construction noise and water quality monitoring locations for
the Project and a map showing these monitoring stations is presented in Appendix D.
3.3.2
Following the proposal
for partial termination of the construction phase EM&A programme
for Contract 2, 4, 7 and SSC505 approved by EPD on 9 July 2020. The corresponding air quality monitoring
stations including AM1c and AM8 were ceased after last monitoring carried out
on 7 July 2020 and 10 July 2020 respectively. Besides, the corresponding noise monitoring
stations including NM1 and NM7 were ceased after last monitoring carried out on
7 July 2020 and 10 July 2020 respectively.

1-hour TSP Monitoring
3.6.1
The 1-hour TSP monitor was a brand named “Sibata LD-3B Laser Dust monitor Particle Mass Profiler
& Counter” which is a portable, battery-operated laser photometer. The 1-hour TSP meter provides a real
time 1-hour TSP measurement based on 90o light scattering. The 1-hour TSP monitor consists of the
following:
(a.)
A pump to draw sample aerosol through the
optic chamber where TSP is measured;
(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 were 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
were used as the monitoring parameter for the time period between 0700-1900
hours on weekdays; and also Leq(15min) in
three consecutive Leq(5min) measurements
is 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 was performed before and
after the noise measurement.
Water Quality
3.6.9
Water
quality monitoring is conducted at the designated locations. The sampling
produce 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 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 Instrument
including YSI PRO20 Handheld Dissolved Oxygen Instrument and YSI 550A
Multifunctional Meter are used for
water in-situ measures, which automates the measurements and data
logging of temperature, dissolved oxygen and dissolved oxygen saturation. Before
each round of monitoring, the dissolved oxygen probe would be calibrated by the
wet bulb method.
3.6.16 A portable AZ8685
pH pen-style meter or YSI Professional Plus 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 A portable Hach 2100Q Turbidimeter is used for in-situ
turbidity measurement. The turbidity meter is capable of measuring turbidity in
the range of 0 – 1000 NTU. StablCal®
Standards of known NTU are used for calibration of the
instrument before and after measurement.
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 are analyzed
with Suspended Solids (SS) as specified in the
EM&A Manual by a local HOKLAS-accredited testing laboratory (ALS Technichem (HK) Pty Ltd HOKLAS registration no. 66).
SS analysis is
determined by the laboratory upon receipt of the water samples using APHA Standard Methods 2540D (namely ALS Method EA-025 as
accredited HOKLAS Scheme) started 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 is
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 presented in
the relevant monthly EM&A reports.
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.

Should non-compliance of the environmental
quality criteria occurs, remedial actions will be triggered according to the
Event and Action Plan which presented in Appendix E.
3.9.1
All monitoring data will be handled by the ET’s in-house data recording and management
system. The monitoring data recorded in the equipment
will be downloaded directly from the equipment at the end of each monitoring
day. The downloaded monitoring data
will input into a computerized database properly maintained by the ET. The laboratory results will be input
directly into the computerized database and checked by personnel other than
those who input the data.
3.9.2
For monitoring parameters that require
laboratory analysis, the local laboratory shall follow the QA/QC requirements
as set out under the HOKLAS scheme for the relevant laboratory tests.
4.1.1
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 corresponding air quality monitoring
stations AM1c and AM8 ceased accordingly, while monitoring at other monitoring
stations continued in the Reporting Period.
