mitigation measures as appropriately.
ES16
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.
ES17
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.

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 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.
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.

4.2.2
As shown in Tables 4-1 to 4-9, all
the 1-hour TSP 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
In the Reporting Period, construction works under the
project have been commenced in Contracts
2, 3, 4, 6, 7 and
Contract SS C505 and noise monitoring was performed at all designated
locations.
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 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
graphical plots are shown in Appendix J.

5.2.2
As shown in Tables
5-1 and 5-2, no
construction noise measurement results that exceeded the Limit Level were
recorded. Moreover, no valid noise complaint (which triggered Action Level
exceedance) was recorded in the Reporting Period.
6.1.1
In the Reporting Period, construction works under the
project has been commenced in Contracts
2, 3, 4, 6, 7 and
Contract SS C505 and water quality monitoring was performed at all designated
locations. The water quality
monitoring schedule is presented in Appendix H. The monitoring results are summarized in
the following sub-sections.
6.2.1
In the Reporting Period, a total of fourteen (14) sampling days was scheduled to carry out for all designated locations
with their control stations. Since exceedances were recorded at WM2A(a) and WM3x, according to ¡§Event and Action Plan¡¨ stipulation, 4 and 2 additional water quality monitoring day were conducted for WM2A(a) and WM3x and its control stations..
6.2.2
During water monitoring on 2 to 12 January 2018, the
access of WM2A(a) for water sampling was demolished due to the construction
work. Therefore, WM2A(a) was temporarily shifted to upstream near
Nylon Dam, which was the only accessible and safe platform to carry out water
sampling. The temporary location of
WM2A(a) is indicated in Appendix E. Sampling at WM2A(a) was resumed to the designated location on 13 January
2018 with the new access provided.
6.2.3
The key monitoring parameters including Dissolved Oxygen, Turbidity and Suspended
Solids are summarized in Tables 6-1 to 6-5. Breaches of water quality monitoring
criteria are shown in Table 6-6. Detailed monitoring database including
in-situ measurements and laboratory analysis data are shown in Appendix
I and the relevant graphical plot are shown in Appendix J.

In this Reporting Period, a total of sixteen (16) Action/ Limit Level exceedances, namely eight (8) Limit Level exceedance of turbidity and eight (8) Action/ Limit
Level exceedances of Suspended
Solids were recorded for the Project and they are summarized in Table
6-5. Investigation Reports
for all water quality exceedances were completed by ET. Investigation results revealed that the
Contractor had properly implemented water quality mitigation measures such as
covering the expose area with tarpaulin sheet and provided bunds align the
watercourse. It was concluded that
the exceedances recorded at WM2A(a) on 8 to 13 January
2018 and WM3x on 8 January 2018 were completed were related to the impact of
rainstorm and not caused by the works under the Project. For exceedances recorded atWM3x on 27 January
2018, it was concluded that the exceedances were related to the external source
of turbid water and not project related.
6.2.5
NOE was issued to relevant parties upon
confirmation of the monitoring result.
The investigation results and summary of exceedances are summarized in Table
6-6. The details of the
completed investigation reports for the exceedances are attached in Appendix
N.

& SS |
In
our investigation, no adverse water quality impact was observed during the
site inspection. Moreover, there
were no rainfall record on 29 December 2017 and muddy runoff from the site
area was unlikely to occur. It
was considered that the exceedances were unlikely caused by the works under Contracts
2 and 3. Nevertheless, the
Contractor of Contract 3 was advised to continuously improve the mitigation measures
to muddy surface from construction site entering the diverted flow
specifically during rain and potential muddy runoff generated by watering
during dusty work. |
8, 9,
10, 11, 12 and 13 Jan 2018 |
WM2A(a) |
NTU
& SS |
According to the weather
information from the Observatory, successive heavy rainstorm was recorded
during 7 to 9 January 2018. The water quality throughout the river course was
highly affected by the stirred up sediment and muddy runoff from the
surrounding environment even outside the construction site. The muddy water
was trapped at the Nylon Dam at intermediate of the construction site. In our investigation, the
Contractor had implemented water quality mitigation measures such as
providing temporary bund and tarpaulin sheet align the river course, there
were no adverse water quality impact observed during the site inspection. Since
the existing river water was found turbid even without adverse water impact
of the site and muddy water was also observed at upstream during the
exceedance days, it is considered that the exceedances were related to the
impact of rainstorm. |
8 Jan
2018 |
WM3x |
NTU
& SS |
According to weather
record from the Observatory, there was heavy rainstorm on 8 January 2018 and
the water quality in the river course was deteriorated by rain and stirred up
sediment. Moreover, storm water from road surface of Sha Tau Kok Road entering WM3x was noted during rainy day. It was concluded that the exceedances
were caused by the rain. |
27 Jan
2018 |
WM3x |
NTU
& SS |
Inspection was carried out
at upstream of WM3x, a vehicle was found parked on the access road in Ng Tung
River, suspecting for channel maintenance by other party and turbid water was
observed since there. The Contractor of Contracts 2 and 6 explained that the
vehicle was not belonging to them as they have no permit to access the channel
area. Moreover, it was observed that the water quality from North Portal Site
and Admin Building Site under Contract 2 and South Portal under Contact 6
were clear and no deteriorated water quality was noted from both Sites. It is considered that the
exceedances were related to other
source of turbid water and not caused by the works under Contract 2. |

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 54th monthly EM&A report presenting the monitoring results and inspection
findings for the Reporting Period from 1 to 31 January 2018.
12.1.1
For
air quality monitoring, no 1-hour TSP and 24-hour TSP monitoring results triggered the Action or
Limit Levels were recorded.
12.1.2
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.
12.1.3
For water quality monitoring, a total of sixteen (16) Action/ Limit Level exceedances, namely eight (8) Limit Level exceedance of turbidity and eight (8) Action/ Limit
Level exceedances of Suspended
Solids were recorded. Investigation
Reports for water quality exceedances were completed which concluded that all
the exceedances were related to the impact of rainstorm/ external source of
turbid water and not caused by the works under the Project.
Environmental Complaint
12.1.4
In this Reporting
Period, one (1) documented environmental complaint was received regarding the
waste management under the EM&A Programme. Investigation for the complaint is
underway and site inspection at complaint location is arranged on 9 February
2018 for investigation.
12.1.5
In
the Reporting Period, no environmental summons and prosecution under the EM&A Programme was lodged for all Contracts.
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 dry season, 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 as appropriately.
12.2.2
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.
12.2.3
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.
12.2.4
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.
12.2.5
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.
