Appendix H and the monitoring
results are summarized in the following sub-sections.
5.2.1
In the Reporting Period, a total of 55 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, NM2, 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 was performed at 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

In the Reporting Period, a total of twelve
(12) sampling days water quality was scheduled to
carry out for all designated locations with their control stations. Since water quality exceedance were
recorded at WM2B and WM4, four (4) and one (1) extra days water quality monitoring
were conducted at WM2B and WM4 respectively and their control stations in
accordance with ¡§Event and Action Plan¡¨.
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

Soil erosion and generation of run-off from the
excavation area at North Portal was happened on 1 and 2 February 2016 during
rainstorm. The exceedances were related to Contract 6. The Contractor had enhanced the mitigation
measures such as covering the open slope as far as practicable to minimize
muddy runoff and construction of sump pit to collect the site runoff. The construction of 2 new sump pits
under the slopes and covering of open slopes were completed on 5 February
2016. |

The
Contractor of Contract 3 was conducted the removal work of
the supporting of Bridge E on 26 February 2016. The removal of broken concrete by an
excavator stirred up the river bed. The exceedances were related to
Contract 3. The
Contractor explained that in order to reinstate the river, this process is
unavoidable. Since the river is fairly shallow in the dry season and working
in the river inevitably disturbed the river bed, very few could be done to
get rid of the impact. As to minimize the impact, the Contractor was managed
to remove broken concrete in 3 days (25 to 27 February 2016). The construction activities carried out by Contract 2
was away from the river course and no discharge was made on 26 February 2016,
it is considered that the exceedances
were not related to Contract 2. |

to improve the performance and prevent soil or mud from leaving on public road
by vehicles from site.
(b)
Desilting
of temporary drainage adjacent to existing wheel washing facility should be
performed more frequently.
(c)
Desilting
of nullah which is connected to Ng Tung River should be performed more
frequently.
(d)
EPD
commented that the wastewater collection at sump pit, diversion and treatment
arrangement should be strengthened in order to ensure the wastewater generated
from the wheel washing activities treated in a more effective way.
(e)
Muddy
water should be prevented from entering the drainage ditch at the Wo Keng Shan Park access.
9.1.10
Site inspection was carried out by the RE,
IEC, Contractor and ET on 3 March 2016 to follow up the water discharge
condition and improvement works conducted by CCKJV. There was no turbid observed at Ng Tung
River. The observation of
improvement works are presented in below.
(a)
A
labor was deployed to wash the haul road and site exit of Bridge A, The site
exit was kept clear of mud and soil and maintained wetted.
(b)
Sand
bag barrier was provided to isolate the active construction area and the haul
road. The haul road was hard paved
and kept clear of mud and soil.
(c)
The AquaSed (SH-06) was function properly and the effluent was
visually clear after frequent desludging.
(d)
Desilting
was carried out at the temporary drainage adjacent to existing wheel washing
facility and the water quality in the temporary drainage was visually clear.
(e)
The
water quality in the nullah after the wheel washing facility connected to Ng
Tung River was visually clear.
9.1.11
CCKJV advised that muddy water cumulated at the drainage
ditch at the Wo Keng Shan access will be cleaned up.
As advised by CCKJV, self-checking of the wastewater treatment facility near
Bridge A was conducted daily to ensure the discharge water fulfill the
requirement of water discharge quality.
The result could be retrieved upon requested. Further enhancement of the wheel washing
arrangement of Bridge A, such as deploy of new washing bay, additional
sedimentation tanks and WetSep and sump pit
modification, are planned. Those
works are scheduled to be commenced on 10 Mar 2016 and will be completed by the
end of March 2016.

9.1.13
On 23 February 2016, a complaint was
received by CEDD regarding the soil/ debris brought by the dump trucks from the
construction site running along Sha Tau Kok Road. Besides, road cleaning by water bowser
carried out by Food and Environmental Hygiene Department was not effectively
remove the soil/ debris and the cumulated muddy water was splashed on the vehicle
passing by the road.
9.1.14
A joint site inspection among the RE, IEC,
Contractor of Contract 6 (CCKJV) and ET was conducted on 25 February 2016 for
the complaint investigation. The
inspected area included the concerned section of Sha Tau Kok Road and three (3)
construction site exits maintained by CCKJV along Sha Tau Kok Road and Wo Keng Shan Road.
Condition of Sha Tau
Kok Road (overview)
9.1.15
During the site inspection, it is observed
that road surface of the concerned section of Sha Tau Kok Road was partially
wetted after road cleaning by water bowser. The road was kept clear of soil/ debris
and no adverse environmental impact especially in road cleanliness was
observed. As advised by the CCKJV, road cleaning by water bowser was carried
out at least 3 times per day on Monday, Wednesday and Friday.
Condition of
Construction Site Exit at Sha Tau Kok Road
9.1.16
During the site inspection, it was observed that
manual wheel washing was provided at the site exit. As
a mitigation measure, a cut-off ditch was constructed in order to divert the
wastewater generated from wheel washing activity to the sump pit to undergo
treatment. However, the
residual water from manual wheel washing was getting into the adjacent Sha Tau Kok Road. There was a cut-off
trench located right before the site exit to incept the residual water from
manual wheel washing but the effectiveness is doubted. During site inspection on 3 March 2016,
the Contractor has enlarged the cut-off trench in order collect the wastewater
as far as possible and the condition of the site exit was improved. Moreover, the Contractor was advised
that the manual wheel washing would only carry out
within the site boundary to prevent wastewater getting into the public
area. As advised by the Contractor,
this site exit will be dismantled in mid-March 2016 due to road diversion and
ET will closely monitor the condition of the site exit in the subsequent site
inspection.
Condition of
Construction Site Exit at Wo Keng Shan Road (Works
Area: Wo Keng Shan)
9.1.17
During the site inspection, it was
observed a wheel washing facilities with associated AquaSed
for wastewater treatment was deployed at the site exit. The condition of the
site exit of and the connected Wo Keng Shan road was
kept clear of soil/
debris and no adverse environmental impact
especially in road cleanliness was observed. As advised by the CCKJV, road cleaning by
water bowser was carried out at Ko Keng Shan least 3
times per day on Monday, Wednesday and Friday.

Since there are many other dump trucks out of the
project running along the Sha Tau Kok Road and no observable oil/debris was
brought out by any trucks of LT/HYW, particularly the Site Exit at Sha Tau Kok
Road maintained by CCKJV, it is considered that the complaint is unlikely to
the Project. Nevertheless, CCKJV
was advised to closely monitor the condition of the site exit and further
improve the wheel washing facilities if necessary.

10.3.2
Contract 4 has not yet commenced and no
environmental issue is presented.
11.1.1
This is the 31st monthly EM&A report presenting the monitoring
results and inspection findings for the Reporting Period from 1 to 29 February 2016.
11.1.2
For air quality monitoring, no 1-hour and
24-hour TSP monitoring results triggered the Action or Limit Levels were
recorded. No NOEs or the associated corrective actions
were therefore issued.
11.1.3
In the Reporting Period, no construction
noise measurement results that exceeded the Limit Level were recorded. However, one (1) noise complaint was
received by 1823 for Contract 3 on 18 February 2016 which triggered the Action
Level (AL). Investigation report
for the complaint was conducted by ET and the result revealed that the
complaint was not related to the works under Contract 3.
11.1.4
For water quality monitoring, a total of
eleven (11) Limit Level (LL)exceedances were recorded, namely six (6) LL
exceedance of turbidity and five (5) LL exceedance of Suspended Solids for the
Project. Specifically, there were
five (5) LL of Turbidity and four (4) LL Level of Suspended Solids recorded at
WM2B and one (1) LL of Turbidity and one (1) LL of Suspended Solids recorded at
WM4. The investigations for the
cause of exceedances have been conducted by the ET and the associated
investigation reports were submitted to relevant parties
11.1.5
No environmental summons or successful
prosecutions were recorded in the Reporting Period.
11.1.6
In this Reporting Period, three (3)
documented environmental complaints were
received for the Project. Specifically, two (2) complaints were related to
Contracts 6 regarding
turbid water and soil/ debris brought by the dump trucks water on 22 and 24 February 2016 respectively.
Besides, one (1) complaint was related to Contract 3 regarding construction
noise issues on 18 February 2016. Follow up
actions have been undertaking by the Contractor to resolve the deficiencies.
Investigation report for complaint on 18 and 24 February 2016 had conducted by
ET whereas 22 February 2016 was underway.
11.1.7
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, 5, 6, 7 and SS C505 in accordance with the EM&A
Manual stipulation. No
non-compliance observed during the site inspection.
11.2.1
In upcoming wet 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 or public area
would be the key issue. The
Contractors should paid special attention on water quality mitigation measures
and fully implement according ISEMM of the EM&A Manual, in particular for
Contract 6.
11.2.2
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.
11.2.3
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.
11.2.4
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.
