Investigation
Reports for water quality exceedances have been conducted by ET
accordingly. Investigation results
revealed that the Contractor had properly implemented water quality mitigation measures
such as well-maintained the wastewater treatment facility and covered the
expose area with impervious sheet. It
was concluded that all exceedances recorded at WM1, WM2A(a) and WM4 as well as
the exceedances recorded at WM3x during 3 to 18 July 2018 were related to the rainstorm or external inflow of muddy water and unlikely caused by the
works under the Project. The investigation report for exceedances at WM3x on 30
July are still underway by ET and the investigation result will be presented in
next Monthly EM&A Report.

Future Key Issues
ES15
During rainy season, preventive measures for muddy
water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma
Wat Channel, Ping Yuen River, Kwan
Tei River
or public area should be properly maintained. The Contractors should paid special attention on water
quality mitigation measures and fully implement according ISEMM of the EM&A
Manual, in particular for working areas near Ma Wat Channel and Ping Yuen
River.
ES16
In addition, all effluent
discharge shall be ensure to fulfill Technical Memorandum of Effluent
Discharged into Drainage and Sewerage Systems, inland and Coastal Waters
criteria or discharge permits stipulation.
ES17
Construction noise would
be a key environmental issue during construction work of the Project. Noise mitigation measures such as using quiet plants should be implemented in
accordance with the EM&A requirement.
ES18
Since most of construction sites under the Project are
located adjacent to villages, the Contractors should fully
implement air quality mitigation measures to reduce construction dust emission.

Note: EPD has
approved the revised EM&A Programme (Rev.7) which proposed that (1) if the
measured water depth of the monitoring station is lower than 150 mm,
alternative location based on the criteria were selected to perform water
monitoring; and (2) 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 in accordance with the updated EM&A Programme (Rev.
07) (Section 4.1.4) (EPD ref.: ( ) in EP2/N7/A/52 Ax(1) Pt.20 dated 7 April
2017)

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.
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.
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 550A Multifunctional Meter 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
A portable AZ Model 8685 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.
3.6.17
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 ¡V 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.

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 45 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 NM1, NM3, NM4, NM5, NM6, NM7, NM8 and NM9. 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 NM10 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

still under investigation.
6.2.3
In this Reporting Period, a total of fifty-five (55) Limit Level exceedances, namely twenty-six (26) Limit Level exceedance of turbidity and twenty-nine (29) Limit Level exceedances of Suspended
Solids were recorded for the Project and they are summarized in Table 6-5. Investigation Reports for water quality exceedances
have been conducted by ET accordingly.
Investigation results revealed that the Contractor had properly implemented
water quality mitigation measures such as well-maintained the wastewater treatment
facility and covered the expose area with impervious sheet. It was concluded that
all exceedances recorded at WM1, WM2A(a) and WM4 as well as the exceedances
recorded at WM3x during 3 to 18 July 2018 were related to the rainstorm or external inflow of muddy water
and unlikely caused by the works under the Project. The investigation report
for exceedances at WM3x on 30 July are still underway by ET and the investigation
result will be presented in next Monthly EM&A Report.

11.3.1
Key
issues to be considered in the coming month for Contracts 2, 3, 4, 6, 7 and SS C505 include:
Implementation of control measures for
rainstorm;
Regular clearance of stagnant water during
wet season;
Implementation of dust suppression measures
at all times;
Potential wastewater quality impact due to
surface runoff;
Potential fugitive dust quality impact due
from the dry/loose/exposure soil surface/dusty material;
Disposal of empty engine oil containers
within site area;
Ensure dust suppression measures are
implemented properly;
Sediment catch-pits and silt removal
facilities should be regularly maintained;
Management of chemical wastes;
Discharge of site effluent to the nearby
wetland, stockpiling or disposal of materials, and any dredging or construction
area at this area are prohibited;
Follow-up of improvement on general waste
management issues; and
Implementation of construction noise
preventative control measures
12.1.1
This is the 60th monthly EM&A report presenting the monitoring results and inspection
findings for the Reporting Period from 1 to 31 July 2018.
12.1.2
For
air quality monitoring, no 1-hour TSP and 24-hour TSP monitoring results triggered the Action or
Limit Levels were recorded.
12.1.3
In the Reporting Period, no construction
noise measurement results that exceeded the Limit Level were recorded. Moreover, no valid noise
complaint which triggered an Action Level exceedance was recorded.
12.1.4
For water quality monitoring, a total of 55 LL exceedances, namely 26 LL exceedance of turbidity and 29 LL exceedances of SS were recorded. Investigation
Reports for water quality exceedances have been conducted by ET
accordingly. Investigation results
revealed that the Contractor had properly implemented water quality mitigation measures
such as well-maintained the wastewater treatment facility and covered the
expose area with impervious sheet. It was concluded that all exceedances
recorded at WM1, WM2A(a) and WM4 as well as the exceedances recorded at WM3x
during 3 to 18 July 2018 were related to the rainstorm or external inflow of muddy water and unlikely caused by the
works under the Project. The investigation report for exceedances at WM3x on 30
July are still underway by ET and the investigation result will be presented in
next Monthly EM&A Report.
12.1.5
In this Reporting Period, no environmental complaints, environmental
summons and prosecution were received under the EM&A programme.
12.1.6
During
the Reporting Period, weekly joint site inspection by the RE, IEC, ET with the relevant Main-contractor
were carried out for Contracts 2, 3, 4, 6 and 7 in accordance with the EM&A Manual
stipulation. For Contract SS C505, weekly
joint site inspection was carried out
by the RE, IEC, ET
and main-contractor
whereas IEC performed
monthly site inspection. No non-compliance observed during the
site inspection.
12.2.1
During rainy season, preventive
measures for muddy water or other water pollutants from site surface flow to local
stream such as Kong Yiu Channel, Ma Wat Channel, Ping
Yuen River, Kwan Tei River or public area should be properly maintained. The Contractors should paid special attention
on water quality mitigation measures and fully implement according ISEMM of the
EM&A Manual, in particular for working areas near Ma Wat Channel and Ping
Yuen River.
12.2.2
In
addition, all effluent discharge shall be ensure to fulfill Technical Memorandum
of Effluent Discharged into Drainage and Sewerage Systems, inland and Coastal
Waters criteria or discharge permits stipulation.
12.2.3
Construction
noise would be a key environmental issue during construction work of the
Project. Noise mitigation measures
such as using quiet plants should be implemented in accordance with the
EM&A requirement.
12.2.4
Since
most of construction sites under the Project are located adjacent to villages,
the Contractors should fully implement air quality mitigation measures to reduce
construction dust emission.
12.2.5
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.
