Future Key Issues
ES15
As wet season is approaching, 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.
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

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 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
There was site
closure for all Contracts except for Contract 2 during Lunar New Year Holiday on 5 to 7 February
2019. As advised by the Contractor
of Contract 2, wastewater generated from construction site has been limited to
wheel washing for some private vehicles and groundwater seepage inside
waterproof tunnel. With the implementation of wastewater treatment facilities,
it was considered that the water quality impact was negligible and therefore
water quality monitoring was suspended on 5 to 7 February 2019.
6.2.2
In the Reporting Period, a total of eleven (11) sampling days were scheduled
to carry out for all designated locations with their control stations. Since exceedance was recorded at WM2A(a) and WM4, according to ¡§Event and Action Plan¡¨ stipulation, 1 additional water quality monitoring day was conducted for WM2A(a) and WM4
and its control station respectively.
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.

Complaint Detail |
Investigation Status |
29 November 2018 (Last Reporting
Period) |
A public Complaint was received on 29 Nov 2018 and referred to ET in
Dec 2018 regarding the emission of dust and muddy road along the Lin Ma Hang
Road in between Tsung Yuen Ha Village and Ta Kwu Ling police station.
(Contract SS C505, Contract 6 and Contract 7) |
In our investigation, the Contractors have implemented dust control
measures as such provide the wheel washing facilities at site exit and
properly maintained cleanliness of site exit and adjoin roads. No cumulated muddy water and mud
trails were observed at the site exit under Contract 6, Contract 7 and
Contract SS C505 and adjoined LMH Road during our inspections. Since there were many other heavy
vehicles apart from LT/HYW Project using LMH Road particularly between Ta Kwu
Ling Police Station and Chuk Yuen Village 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. The IR without comment from IEC was shown in Appendix O. |
30 January 2019 (Last
Reporting Period) |
A complaint was received
by EPD on 30 January 2019 about emission of construction dust from Chun Wo
construction site near Food and Environmental Hygiene Department (FEHD)'s Refuse
Collection Point (RCP) near Bridge Pier ID TP-60. (Contract 3) |
In our investigation, the Contractor has implemented dust control
measures such as providing adequate wheel washing at site exit, road cleaning
by water tanker for entire site and covered stockpile when not in used. There were no Record of Inspection
(yellow/ pink inspection form) issued by EPD and no non-compliance observed
during site inspection. It
is considered that the complaint was not related to the works under the
Contract work. The IR without comment from IEC was shown in Appendix O. |
28 January 2019 (received
by ET on 14 Feb 2019) |
A public complaint was
received by EPD on 28 January 2019 about noise disturbance generated by the
construction works at 8pm at Kau Lung Hang claiming from Chun Wo¡¦s
construction site (Contract 3). |
As confirmed by Chun Wo,
there was no construction activity after 18:00 on 28 January 2019. EPD had
also conducted surprise check after the complaint and no non-compliance
was observed. It is considered that the complaint is not valid to
Contract 3. The IR without comment from IEC was shown in Appendix O. |
21 February 2019 |
A public complaint was received
by 1823 on 21 Feb 2019 about cleanliness of Chun Wo construction site near
Yuen Leng concerning on water spraying around the site area causing mud and
muddy water rush out from the site to public road. (Contract 3). |

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 67th monthly EM&A report presenting the monitoring results and inspection
findings for the Reporting Period from 1 to 28 February 2019.
12.1.2
For
air quality monitoring, no 1-hour TSP and 24-hour TSP monitoring results triggered the Action /Limit Level was 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
In this Reporting Period, four (4) Limit
Level exceedances, namely two (2) LL of turbidity and two (2) LL of
Suspended Solids were recorded for the Project. The investigation
report for exceedance recorded at WM2A(a) on 8 February 2019 revealed that
exceedance was not related to the work under the project. The investigation report for exceedance
recorded at WM4 on 25 February 2019 is underway by ET and the investigation result
will be presented next month.
12.1.5
In this Reporting Period, two (2) documented environmental complaints were received in
relation to Contract 3. The first complaint was
received on 28 Jan 2019 regarding noise disturbance from C3¡¦s construction site
at 8pm. The C3¡¦s Contractor confirmed that there was no construction activity
after 18:00 on the concerned date. Investigation was conducted by ET and
the IR revealed that the complaint was not valid to the Project. The second complaint was received on 21
Feb 2019 about cleanliness of Chun Wo construction site near Yuen Leng

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
As wet
season is approaching, 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.
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.

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.
