ES.04. Investigation
report for the 24-hour TSP monitoring was completed by ET. Investigation
results revealed that the Contractor had properly implemented dust mitigation
measures such covering of the stockpile and providing water spraying for dusty
haul road and dusty area. Since
Joss paper burning was suspected to be conducted during period of sampling,
which affecting the monitoring result, it was conducted that the exceedance was
not caused by the works under the Project.
ES.05. Investigation
Report for all water quality exceedances was completed by ET. 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 the exceedances were related to
the unknown source of muddy water contributed from outside the project area and
not caused by the works under the Project. Nevertheless, the Contractor was
reminded to fully implement the water quality mitigation measure throughout the constriction phase as far as practicable.
Environmental
Complaint
ES.06. In this Reporting Period, four (4) documented environmental complaints were received
regarding the dust and water
quality issues under the EM&A Programme. The Investigation Reports for the complaints were completed by ET
without further comments from IEC.
Notification of Summons and Successful Prosecutions
ES.07. No environmental summons or successful
prosecutions were recorded in the Reporting Period.
Reporting Changes
ES.08. No
reporting changes were made in the Reporting Period.
Future key issues
ES.09. 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.
ES.10. 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.
ES.11. 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.
ES.12. 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)

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.

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 Instrument
including YSI PRO20 Handheld Dissolved Oxygen Instrument or 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. Before
each round of monitoring, the dissolved oxygen probe would be calibrated by the
wet bulb method.
3.6.15 A portable 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

In the
Reporting Period, 24-hour TSP
monitoring at AM1b has been temporary suspended since 27 April 2018 as the area
for AM1b was demolished and returned to the landlord. Alterative location is being seeking by
ET for IEC and EPD approval.
4.2.4
In the
Reporting Period, all the 1-hour TSP monitoring results were
below the Action/Limit Levels. For 24-hour TSP,
there was 1 Limit Level exceedance recorded specifically at AM9b on 28
Feb 2018. Notification of Exceedance (NOE) was issued to relevant
parties upon confirmation of the result and Investigation Reports for the
exceedances have conducted by ET accordingly. Investigation results revealed
that the Contractor had properly implemented dust mitigation measures such
covering of the stockpile and providing water spraying for dusty haul road and
dusty area. Since Joss paper
burning was suspected to be conducted during period of sampling at AM9n, which
affecting the monitoring result, it was conducted that the exceedance was not
caused by the works under the Project.
4.2.5
The summary of weather conditions during the Reporting
Period is presented in Appendix G.

6.2.4
In the Reporting Period, a total of 11 Limit Level (LL) exceedances, namely 6 LL exceedance of turbidity and 5 LL exceedances of
Suspended Solids were recorded. NOEs were issued
to relevant parties upon confirmation of the results.
6.2.5
Investigation
reports for the exceedance were conducted by the ET and the investigation
results revealed that all exceedances were not related to the works under the project. The detailed
investigation reports are summarized in Table 6-6 and presented in the relevant
monthly EM&A reports.

WM2A(a) |
NTU & SS |
According to the weather information from the Observatory, there was heavy rainstorm on 31 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. According to the site
photos on 31 January 2018, muddy water was
observed throughout the river course including control station. 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, it is considered that the exceedances were related to the residual impact of rainstorm.

WM2A(a) |
NTU & SS |
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 there were no construction
activities on 16 to 20 February 2018 and no rainfall record during that
period, wastewater and muddy runoff was generated from the construction site
was not anticipated. It is considered that the exceedances were not related the
works under the Contract |
1
and 3 March 2018 |
WM3x |
NTU & SS |
Upon detection of the
exceedances, inspection was carried out at the channel adjacent to related
site areas of Contract 2 and Contract 6, no deteriorated water quality was
observed from both Sites. Moreover, weekly site inspection revealed that both
Contractors had properly implemented water quality mitigation measures and no
adverse water quality impact was recorded. It is considered that the exceedances were related to other source of turbid water,
possibly from storm water of Sha Tau Kok Road or adjacent
villages and not caused by the
works under the Project. |
16
and 17 April 2018 |
WM4 |
NTU & SS |
On 16 April 2018, the Contractor reported that unknown source of muddy
water attributed to site area and the muddy water was finally entered Ma Wat
River. On 17 April 2018, inflow of turbid water to Ma Wat River was observed and the source
of unknown turbid water was out of the site boundary. In our investigation, no
adverse water quality impact was observed during the site inspection for both
sites of Contracts 2 and 3. It
was considered that the exceedances on 16 and 17 April 2018 were related to
unknown source of muddy water outside the site boundary and unlikely caused
by the works under the project. |

Complaint Detail |
Investigation
Status |
28 February 2018 |
A public complaint was received from Project Hotline regarding the
cleanliness of Sha Tau Kok (STK) Road ¡V Ma Mei Ha
Section (Dust and Water Quality) |
Investigation was carried out for related Contract 2 and Contract 6
accordingly. The IR revealed that the Contractors have been well maintained
the wheel washing facilities and no dust and soil carrying by site vehicles
to STK road were observed. The
complaint was suspected to be caused by frequent use of dump truck
transporting loose material to NENT and the majority of dump truck was not
belong to LT/HYW project. |
4 March 2018 |
A public complaint was received via 1823 regarding the cleanliness of
Lin Ma Hang Road. (Dust and Water Quality) |
Investigation was carried out for related Contract 6, Contract 7 and
Contract SS C505 accordingly. The IR revealed that the conditions of all site
exits under the project were well maintained without mud and debris and no
excessive water spraying and slurry was found on LMH road. However, a
deficiency at Gate 1 under Contract 6 was observed and rectified immediately
without affecting the public.
Since there were many other heavy vehicles apart from the project using
LMH Road and certain number of unknown exit sites without proper management
along LMH Road, it is considered that the complaint was not related to the
works under the Project |
13 April 2018 |
EPD
had received a complaint regarding foams in water discharged from the North
Portal Site of Contract 2. |
As advised the Contractor, the incident was
caused by the damage on the transfer pipe during the filling of Polyfoamer from another intermediate bulk container
(IBC) tank, resulting in spattering out the Polyfoamer. The operator immediately turned off
the chemical transfer pump to minimize the spillage, however, some Polyfoamer had already entered into the TBM dewatering
system and eventually reached the wastewater treatment facilities. To avoid
reoccurrence of the incident, DHK has set up precautionary measures. In our investigation, it is considered that the
incident and complaint was an isolated case in which remedial
action was taken immediately. Furthermore,
DHK advised that TBM breakthrough was finished on
27 April 2018 and no more Polyfoamer and de-foaming
agent would be used for the remaining period of the contract work. |
29 April 2018 |
A public
complaint was received from ASD regarding the muddy water flowing from the
construction site of Contact SS 505. |
Inspection was conducted by ET for the complaint
investigation. It was observed that
mitigation measures were implemented to prevent outflow of muddy water to
other Contract and public area.
Moreover, the boundary of BCP is surrounded by chain link fencing with
concrete foot to prevent site runoff overflowing from the site. It is considered that the complaint
was not related to the works under Contract SS C505. |

12.1.1 This is
the 19th Quarterly EM&A
Summary Report presenting the monitoring results and inspection findings for
the Reporting Period from 1 February to 30 April 2018.
12.1.2 For air quality monitoring, no 1-hour TSP
monitoring results triggered the Action or Limit Levels. For 24-hour TSP, there was 1 Limit Level exceedance
recorded and Notification of Exceedances (NOEs) was issued to relevant
parties upon confirmation of the result.
Investigation for the cause for the exceedance was completed by ET which
concluded that the exceedance was related to the external source of dust
emission and not caused by the works under the Project.
12.1.3 In the
Reporting Period, no construction noise exceedances were
recorded and no complaints (which triggered
the Action Level exceedance) were
received.
12.1.4
For water quality monitoring, a total of 11 Limit Level, namely 6 LL exceedance of turbidity and 5 AL/LL exceedances of
Suspended Solids were recorded for the Project. Investigation reports 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
the exceedances were not related to the works under the Project
12.1.5 In this Reporting Period, Quarterly
Ecological Monitoring Report for woodland compensation (Dec 2017 to Feb 2018) was submitted to EPD in March 2018. In addition, ecological monitoring for woodland compensation for
period of March to May 2018 was carried out on 19 and 20 March 2018 and the corresponding Quarterly Ecological Monitoring Report was
submitted to EPD in June 2018.
12.1.6 In this Reporting Period, four (4) documented environmental complaint was received regarding
the air quality and noise issues under the EM&A Programme. The Investigation Reports for the complaints were completed by ET
without further comments from IEC.
12.1.7 No environmental summons or successful
prosecutions were recorded in the Reporting Period.
