4.2.1
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.
4.2.2
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, 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 40 event 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, the noise level measured at all designated monitoring
locations were below 75dB(A). Moreover, no valid noise complaint (which triggered Action Level
exceedance) was recorded in the Reporting Period.
5.3.1
In
the Reporting Period, CNPs were granted by Contracts 2, 3, 6, 7 and SS C505 for
use of Powered Mechanical Equipment (PME) during restricted hour. As confirmed by both Contractors with
their works schedules, construction works would be conducted at Contract 2, 3, 6 and SS C505 during
restricted hours with the granted CNP.
Noise monitoring was therefore conducted at the relevant noise
monitoring locations during respective restricted hour periods.
5.3.2
Based on the works schedule by the Contractor of Contracts 2,
3, 6, 7 and SS C505, the involved noise
monitoring locations included NM1, NM4, NM5, NM7, NM8, NM9
and NM10 and the noise
monitoring results are summarized in Tables 5-3 and 5-4.

5.3.3
According to the site
records by the monitoring team, no construction noise from the construction was
noted during the course of monitoring at all locations. On the other hand, traffic noise was
dominated at NM8 and NM9 since the monitoring locations were closed to the
train tracks and occasionally noise from vehicle
and dogs barking were recorded at all stations. Therefore, it is considered that the
measurement results were likely to be the background noise.
6.1.1
In the Reporting Period, construction works under the
project has been commenced in Contracts 2,
3, 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 twelve (12) sampling days was scheduled to carry out for all designated locations
with their control stations. Since
exceedances were recorded at WM1, WM2A(a) and WM3x, according to ¡§Event and Action Plan¡š stipulation, one (1) additional water quality monitoring day was
conducted for WM1 and WM3x and two (2) additional water quality monitoring days were conducted for WM2A(a) its
control stations in the
reporting period.
6.2.2
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.

Other Contracts
9.2.12
Since the construction work of Contract 5 has
substantially completed and Contract 4 has not commenced, no site inspection was
performed.
10.1.1
In
the Reporting Period, no summons and prosecution under the EM&A Programme was lodged for all Contracts.
However, one (1) documented environmental complaint regarding noise issue
for Contract 6 in January 2017 was received in the
Reporting Period. The investigation details for
the complaint and status are presented below.
Investigation Result for the Documented Complaint received by EPD on 25 January 2017 (Contract 2) (last Reporting
Period)
10.1.2
EPD
received a complaint from the public who provided photos and video showing grey
slurry was discharging to Kwan Tei River. According to the photo and video
provided, the river was polluted by the grey slurry and part of the harden
slurry was deposited at the river side which seriously affecting the ecology of
the river course. The complainant requested
the related department to follow up and promptly clean up the slurry.
10.1.3
EPD
stated that since the channel and stream was repeatedly being polluted and it
seems that the discharge may be come from the construction site of CEDD's
Contract No. CV/2012/08 - Liantang / Heung Yuen Wai
Boundary Control Point Site Formation & Infrastructure Works, Contract 2,
near Po Kak Tsai.
10.1.4
On
EPD¡Šs inspection on 11 January 2017, the section of the channel just outside
the construction site was clean without slurry. However, in EPD subsequent inspection on
25 January 2017 found that the aforesaid section was accumulated with grey
slurry.
10.1.5
Joint
site inspection among the RE, IEC, Contractor of Contract 2 (DHK) and ET was
carried out on 27 January 2017 in Mid-Vent Portal works and its downstream
channel for the complaint investigation. The observations during site
inspection are summarized below.
(a)
Wastewater treatment
facility was implemented at construction site of Mid-Vent Portal works
area. It comprises of 5 nos. of
sedimentation tanks, 3 nos. of de-silting pit, a WetSep
and an AquaSed. The
treated water was stored in the recycle water silo and discharge would be made
when the water silo is full.
(b)
In view of the
current site condition, the majority of wastewater was generated from the tunnel. The wastewater generated inside the
tunnel was pumped to the wastewater treatment facility for treatment prior
discharge at the approved discharge point.
(c)
There was discharge made from the Mid-Vent Portal works area during the site
inspection and the quality of discharge was visually clear.
(d)
The sections of
channel at downstream Mid-Vent Portal works area was found cumulated with mud
and slurry at the channel bed.
10.1.6
As
advised by DHK, cleansing of the channel at downstream of Mid-Vent Portal works
area was carried out between 17 and 27 January 2017 as well as early February
2017 in accordance with the cleansing proposal which accepted by DSD on 16
January 2017. The cleansing
proposal includes a combination of manual clearance, use of suction trucks and
cleansing by clean water. DHK explained that the section of the stream
where cleansing work was in progress, people might see muddy water flowing
along the stream. Nevertheless, they had installed silt screens and sand
trap during the cleansing work at downstream of the cleansing area to avoid
silt and mud being washed downstream.
10.1.7
Subsequent
joint site inspection among the RE, IEC, Contractor of Contract 2 (DHK) and ET
was carried out on 3 and 10 February 2017 in Mid-Vent Portal works area and
Kwan Tei River to follow up the complaint
investigation. The observations during site inspection are summarized below.
(a)
Wastewater treatment
facility was implemented at construction site of Mid-Vent Portal works area and
the setting and layout of the facility are the same as previous months.
(b)
There was discharge made from the Mid-Vent Portal works area during the site
inspection on 3 and 10 February 2017 and the quality of discharge were visually
clear.
(c)
The channels at
downstream of Mid-Vent Portal works were clear of mud and slurry on 3 and 10 February
2017.
(d)
The water quality
at Kwan Tei River was visually clear and the river
channel was clear of mud and slurry on 3 and 10 February
2017.
10.1.8
In
our investigation, the suspected complaint location was where the cleansing
work was in progress, so the public might see muddy water flowing along the
stream. Nevertheless, DHK has installed
silt screens and sand trap at the downstream area of the cleansing work to avoid
the muddy water being washed downstream. As advised by DHK, they have cleared
the sludge and DSD has no further comment during the joint inspection with DSD
and AECOM on 8 February 2017.
10.1.9
As
suggested by EPD, CEDD considers adding an additional water quality monitoring
station in Kwan Tei River and the proposal for the additional
monitoring work is under reviewed by CEDD.
Nevertheless, ET will keep closely monitor the site condition and status
of implemented mitigation measures by DHK in weekly site inspection.
