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.
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 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.
3.6.12 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.
3.6.13 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
3.6.14 YSI PRO20
Handheld Dissolved Oxygen Instrument
is 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.
3.6.15 A portable EcoSense ®
pH10A pen-style meter or AZ8685 pH pen-style meter is used for in-situ
pH measurement. The pH meter is
capable of measuring pH in the range of 0 ¡V 14 and readable to 0.1.
3.6.16 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 ¡V 1000 NTU. StablCal®
Standards of known NTU are used for calibration of the instrument
before and after measurement.
3.6.17 All
in-situ measurement equipment are calibrated by HOKLAS
accredited laboratory of three month interval.
Laboratory Analysis
3.6.18 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

9.2.3
Since the construction works at the Contract
4 and Contract 6 are not yet commenced, no environmental complaint, summons and
prosecution are received in the Reporting Period accordingly.
10.1.1
The environmental mitigation measures that
recommended in the Implementation Schedule for Environmental Mitigation
Measures (ISEMM) in the approved EM&A Manual covered the issues of dust,
noise, water and waste and they are summarized presented in Appendix
J.
10.1.2
All contracts under the Project shall be
implementing the required environmental mitigation measures according to the approved
EM&A Manual as subject to the site condition. Environmental mitigation measures
generally implemented by Contract 5 in this Reporting Period are summarized in Table
10-1.
Table 10-1 Environmental
Mitigation Measures
Issues |
Environmental Mitigation Measures |
Water Quality |
¡P Wastewater to be treated by
the filtration systems i.e. sedimentation tank or AquaSed before to discharge. |
Air Quality |
¡P Maintain damp / wet surface
on access road ¡P Keep slow speed in the sites ¡P All vehicles must use wheel
washing facility before off site ¡P Sprayed water during
breaking works ¡P A
cleaning truck was regularly performed on the public road to prevent fugitive dust emission |
Noise |
¡P Restrain operation time of plants
from 07:00 to 19:00 on any working day except for Public Holiday and Sunday. ¡P Keep good maintenance of
plants ¡P Place noisy plants away from
residence or school ¡P Provide noise barriers or
hoarding to enclose the noisy plants or works ¡P Shut down the plants when
not in used. |
Waste and Chemical
Management |
¡P On-site sorting prior to
disposal ¡P Follow requirements and
procedures of the ¡§Trip-ticket System¡¨ ¡P Predict required quantity of
concrete accurately ¡P Collect
the unused fresh concrete at designated locations in the sites for subsequent
disposal |
General |
¡P The site was generally kept
tidy and clean. |
11.1.1
This is the 5th Quarterly EM&A Summary Report presenting the monitoring results
and inspection findings for the Reporting Period from 1 August to 31 October 2014.
11.1.2
In the Reporting Period, no 1-hour TSP
monitoring results were triggered the Action or Limit Level. However, a total of three (3) Action
Level exceedances of 24-hour TSP were recorded at AM2 and AM3 and AM7b. NOE was issued to relevant parties upon
confirmation of the monitoring result and investigation for the cause of
exceedance concluded that the exceedances were not related to the works under
the project.
11.1.3
No noise complaint (which is an Action Level exceedance)
was received. However, one (1) noise exceedance was recorded at NM7 on 9 August
2014. Investigation for the cause of exceedance has completed and it was concluded that the exceedance was due to
cumulative noise by the works under Contract 2
as well as the external noise from other workshop and construction works nearby. The Contractor was advised to adopt good
site practice to minimize the construction noise impact where similar work would be conducted in near future.
6.2.9
For water quality monitoring, no Action/Limit Levels exceedance was
triggered according to the set out water quality criteria in Dissolved Oxygen. However, one (1)
Action Level exceedances and fifteen (15) Limit Level exceedances of the
parameters of turbidity and SS were recorded from water samples collected at
WM1 during the Reporting Period, specifically on 14, 16, 18, 21, 23, 25 August
2014 and 10, 13 and 16 September 2014. One (1) Action Level and one (1) Limit
Level exceedances of the parameters of turbidity and SS were recorded from
water samples collected at WM4 during the Reporting Period, specifically on 12
August 2014. NOEs were issued to
relevant parties upon confirmation of the results. The investigation for the
causes of exceedances was completed and it concluded that the exceedances were
not related to works under the Project.
11.1.4
During the Reporting Period, 14 events of
joint site inspections conducted for Contract 2, and 13 events of joint site
inspections for both Contract 3 and Contract 5 were undertaken to evaluate the
site environmental performance. No adverse environmental impacts were observed
during the weekly site inspection and environmental audit of the Reporting
Period, indicating the implemented mitigation measures for air quality,
construction noise and water quality were effective. Minor deficiencies found in the weekly
site inspection were in general rectified within the specified deadlines. The environmental performance of the
Project was therefore considered satisfactory.
11.1.5
In the Reporting Period, no environmental
complaint, notification of summons or successful prosecution under the Project was received.
11.2.1
As dry season is approaching, special
attention should be paid on the potential construction dust impact since most
of the construction sites are adjacent to villages. The Contractor should fully implement
the construction dust mitigation measures properly.
11.2.2
Muddy water or other water pollutants from
site surface runoff into Kong Yiu Channel
and Ma Wat Channel should also be alerted. Water quality mitigation measures to
prevent surface runoff into nearby water bodies should be fully implemented.
11.2.3 Construction noise should be a key environmental impact during the
works. The noise mitigation
measures such as use of quiet plants or temporary noise barrier installation at
the construction noise predominate area should be implemented as accordance
with the EM&A requirement.
11.2.4
Furthermore, daily cleaning and weekly tidiness shall be properly performed
and maintained. In addition, mosquito control should be kept to prevent
mosquito breeding on site.
