Future Key Issues
ES14
As wet season has come, 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 working areas near Ma Wat Channel and Ping Yuen
River.
Moreover, 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.
ES15
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.
ES16
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.

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, 5, 6, 7 and Contract SS C505 and noise monitoring was performed at all
designated locations.
5.1.2
Relocation of Noise Monitoring Location NM2
to NM2a was proposed and verified by IEC on 6 May 2016 and was effective on 9
May 2016.
5.1.3
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 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). Furthermore,
there was one noise complaint (Action Level exceedance) received from 1823 on
20 June 2016 and further clarification with the complainant by RE on 24 June
2016. Therefore, one Action Level exceedance was triggered.
6.1.1
In the Reporting Period, construction works under the
project has been commenced in Contracts 2,
3, 5, 6, 7 and Contract SS C505 and water quality monitoring was performed at all
designated locations. The water

monitoring results are summarized in the following sub-sections.
6.2.1
In the Reporting Period, a total of thirteen
(13) sampling days was scheduled to carry out for all designated locations with
their control stations. Except for
WM3, total thirty-one (31) Limit Level (LL) and one (1) Action Level (AL) of water
quality exceedances were respectively recorded at the monitoring stations WM1,
WM2A, WM2B and WM4. According to ¡§Event
and Action Plan¡¨ stipulation, additional water quality monitoring days respectively
were conducted one day for WM1 and its control station, seven days for WM2A and
its control station, one days for WM2B and its control station, one day for WM4
and its control stations.
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

6th June 2016 |
WM1 (C5, C6 and SS C505) |
NTU & SS |
According
to the Daily Extract of Meteorological Observations from the Hong Kong
Observatory, heavy rainfall was recorded on 6 June 2016. Water flow rate
increased vigorously under the heavy rain and the sediment at the river bed
was stirred up, resulting in turbid water. According to the field photos,
accumulation of rubbish were observed at the bar screen of the box culvert
near WM1 after heavy rainstorm on 6 June 2016. Water flow near WM1 was
therefore retarded and turbid water was cumulated at WM1. Also, water level
at the box culvert increased to a high level due to the combined effect of
heavy rain and accumulation of rubbish, overflow of the Kong Yiu River occurred. Hence, it
is considered that the exceedance on 6 June 2016 was due to the heavy rain and
accumulation of rubbish at the bar screen of the box culvert near WM1, and
unlikely due to the construction activities of the Contract. |
4th,6th, 7th, 8th,
13th, 14th, 15th 16th, 17th,
18th, 20th, 21th, 30th June 2016 |
WM2A (C6) |
NTU &SS |
Exceedances on 4th,
6th, 7th, 8th June 2016 During
joint site inspection with RE, IEC, ET and Contractor on 2 June 2016, it was
observed that unknown source of turbid water was seeping out from the river
bed at upstream of WM2A continuously, turning the water in the river turbid. From the
photo taken by the Contractor on 4 June 2016, it was observed that turbid
water was seeping out from the river bed at upstream of WM2A continuously.
Thus, it is considered that the exceedance on 4 June was likely due to the
unknown source of turbid water. According
to the Daily Extract of Meteorological Observations from the Hong Kong Observatory,
intense rainfall (100-150 mm) was recorded at Ta Kwu
Ling monitoring station on 6 June 2016. Under the intense rain, water flow
rate increased vigorously and the sediment at the river bed was stirred up at
WM2A, resulting in turbid water. As the river bed at WM2A-C was mostly small
rocks, the stirred up of sediment at WM2A-C was limited. The turbid water
recorded at WM2A-C may due to runoff from upper stream or surrounding slopes. According
to the Daily Extract of Meteorological Observations from the Hong Kong
Observatory, heavy rainfall (10-20 mm) was recorded at Ta Kwu
Ling monitoring station on 7 and 8 June 2016. Water flow rate increased and
the stirred up sediment could not settle down in a short period of time after
intense raining on 6 June 2016. The river bed at WM2A was cumulated with
thick silt and sediment, while the river bed at WM2A-C was mostly small
rocks. Hence, sediment stirred up more vigorous in WM2A while the stirred up
of sediment at WM2A-C was limited. It is considered that the exceedances on
6, 7 and 8 June at WM2A were related to the heavy rainfall. Exceedance on 30th
June 2016 During weekly
joint site inspection with RE, IEC, ET and Contractor(CCKJV)
on 30 June 2016, no discharge and surface runoff was observed from the
site. As water mitigation
measures, wastewater treatment facilities including one AquaSed
and three series of sedimentation tank have been installed for piling work
and most of the time the wastewater was recirculated. However, it was
observed that unknown source of turbid water was seeping out from the river
bed. Hence, it is considered that the exceedance on 30 June 2016 was due to
the above event. Exceedance on 13th,
14th, 15th 16th, 17th, 18th,
20th, 21th June During
joint site inspection with RE, IEC, ET and Contractor (CCKJV) on 16 June
2016, no surface runoff was observed from the site into the river. As
advised by the Contractor, the source of turbid water recorded at WM2A was
identified. Due to continual heavy loading, uneven ground and cracks on the
haul road were formed. As dust
suppression measures, a series of sprinklers was installed along the haul
road for continuous spraying and the excessive water was cumulated on uneven
ground/ cracks. When vehicles
passed the puddles, muddy water trapped on the uneven ground/ cracks was
spilled from the road into a channel connecting to Ping Yuen River. To
resolve the deficiency, the Contractor has filled the uneven ground and reduce the frequency of water spraying on that area. Also,
the haul road was levelled up to avoid muddy runoff. The situation was found improved
during site inspection on 7 July 2016. There was
no exceedance recorded in the subsequent monitoring days on 22, 23 June 2016.
Hence, it is considered that the rectification measures carried out by the
Contractor were effective in preventing further exceedances. |
6th

WM2B (C6) |
NTU &SS |
According
to the Daily Extract of Meteorological Observations from the Hong Kong Observatory,
heavy rainfall was recorded on 6 June 2016. The flow rate of the river
increased vigorously, sediment and cumulated silt at the river bed was
stirred up during rain, resulting in turbid water in river channel. Apart
from the disturbance of cumulated silt at the river bed during rain, it was
observed that trails of muddy runoff from the public road surface into the
existing channel under the rain. Thus, it is considered that the exceedance
on 6 June 2016 is due to the heavy rainfall. |

WM4 (C2 and C3) |
NTU &SS |
According
to the Daily Extract of Meteorological Observations from the Hong Kong
Observatory, heavy rainfall was recorded on 6 June 2016. Water flow rate
increased vigorously under the heavy rain and the sediment at the river bed
was stirred up, resulting in turbid water. It is
considered that the exceedances were due to the heavy rainfall and unlikely
related to the construction activities under the Contracts. |

Investigation Result for the Documented
Complaint received by 1823 on 28 April 2016
9.1.2
A complaint was received on
28 April 2016
regarding suspected muddy water discharged from the construction site,
affecting the growth of crops and condition of soil in farmland at junction of
Wo Keng Shan Road and Ng Chow Road. The complainant
also claimed that the gravestone was disappeared due to the construction
activities in the above location.
9.1.3
As the
exact location of the disappeared gravestone cannot be provided by the
complainant, investigation regarding to it cannot be conducted.
9.1.4
According to Contractor¡¦s record (CCKJV),
starting from the project¡¦s commencement, there is only one report of
accidental leakage of muddy water from the site into the nearby farmland on 4
January 2016. Since after that, contractor and ET do not receive any record or
complaint regarding to the discharge of muddy water to the nearby farms.
9.1.5
During weekly joint site inspections with
RE, IEC, ET and Contractor, no leakage of muddy water to the nearby farms was
observed.
9.1.6
As advised by
the Contractor (CCKJV), the construction activities in the above location is
mainly bored piling work. This construction activity unlikely generates any
chemicals that contaminate the soil and adversely affect the growth of crops.
9.1.7
To collect
runoff due to the rain, the Contractor has provided mitigation measures such as
site hoardings, concrete blocks, sandbags and temporary drainage. Also, it is
advised that runoff due to the rain unlikely contains any chemicals that
contaminate the soil and adversely affect the growth of crops.
9.1.8
On 26 May 2016, a joint site inspection
was carried out with RE, IEC, ET and Contractor, the findings during the site
inspection are summarized below:
(a) No leakage of soil or muddy water was observed from
the site to the concerned farm.
(b)
Site hoardings, concrete blocks and
sandbags barriers have been constructed along the boundary of the farm.
(c) Temporary
drainage was constructed and regularly maintained. Runoff is collected and
diverted to treat in wastewater treatment facilities including the
sedimentation tank and AquaSed. (As advised by the
Contractor, in order to further enhance the performance of collecting runoff,
water pump was provided to pump runoff in the temporary drainage to the
wastewater treatment facilities)
9.1.9
Based on the site observations and the
work activity of the site, the complaint regarding to discharge of muddy water from
the construction site, affecting the growth of crops and the condition of soil is not evidenced. Nevertheless, the
Contractor (CCKJV) is reminded to follow the mitigation measures as recommended
in the EM&A Manual. The ET will continue inspect the environmental
performance of the construction site and ensure all activities comply with the
relevant environmental contractual requirement.
Investigation Result for the Documented
Complaint received by 1823 on 21 April 2016
9.1.10
A complaint was received from 1823 on 21
April 2016 and passed to CEDD and EPD. There are two concerns. Firstly, it is
suspected that dump
trucks were not washed in wheel washing facilities before leaving the site and
the site had not carried out water spraying. Hence, these suspected concerns
lead to dust nuisance to the nearby farmlands. Secondly, it is suspected that
the Contractor discharged wastewater directly into the storm drain and Ng Tung
River, affecting the residents and farmers of Tai Tong Wu.
9.1.11
A joint inspection was carried out by the Contractor,
CEDD and RE on 21 April 2016. The inspected area included the wastewater treatment
facilities (AquaSed SH-15) of C6 (CCKJV). CEDD has
not given any adverse comments.
9.1.12
Dust
As
advised by Contractor C6(CCKJV), they have carried out
dust suppression measures to minimize construction dust impact. For instance,
(a) Use of regular watering to reduce dust
emissions from the construction sites, particularly during dry weather.
(b) Establishment and use of wheel washing
facilities at the exit points of the site.
During
weekly joint site inspection with RE, IEC, ET and Contractor on 7 April 2016,
it was observed that wheel washing facilities was provided at vehicle exit
point. Also, the exit was hard paved. The cleanliness condition of the site
exit connecting to Sha Tau Kok Road was satisfactory.

taken to stop the leakage and the muddy water on the public road was also
cleaned up by 12:15 noon.
9.1.55
As reported by C5, a private trailer driving
through a muddy ground to Lin Ma Hang Road was recorded in the afternoon on 10th
June 2016. Afterward muddy trails were found on road where is within the
complaint¡¦s location in Lin Ma Hang Road.
9.1.56
According to the Hong Kong Observatory record,
about 20mm ~ 30mm rainfall was recorded in North District at 12 noon to 2 p.m.
on 10 June 2016. As one of the considerations, the rainwater could cumulate in
the uneven ground surface on Lin Ma Hang Road and cause puddle.
9.1.57
In conclusion, firstly immediate corrective actions
for the incident of leakage to stop the leakage and to clean up muddy water on
the road were taken by C6 within an hour. Furthermore, the location of leakage
was not within the complaint¡¦s area. Secondly, rainwater accumulated in the
uneven ground surface in Lin Ma Hang Road could possibly happened
during and after the rainfall. Thirdly, private trailer causing muddy trails
within the complaint¡¦s area was recorded and the puddle could lead to the
occurrence of muddy water. Finally, based on our observations from the
investigation on 14th June 2016, it
is considered that the mud
on Lin
Ma Hang Road is unlikely due to the Contract 5 (SRJV),
Contract 6 (CCKJV), Contract 7 (KRSJV) and SS C505 (Leighton).

Since the construction work of Contract 4 has
not commenced, no
environmental issue is presented.
11.1.1
This is the 35th monthly EM&A report presenting the monitoring
results and inspection findings for the Reporting Period from 1 to 30 June 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
One
noise complaint (which is an Action Level exceedance) was received and no
construction noise measurement results that exceeded the Limit Level were
recorded in the Reporting Period. The associated investigation report was
submitted to relevant parties. No NOEs or the
associated corrective actions were issued.
11.1.4
For
water quality monitoring, a total of thirty-two (32) Action/ Limit Levels (AL/LL)
exceedances, namely fifteen (15) LL exceedances and one (1) AL exceedance of
turbidity and sixteen (16) LL exceedances of Suspended Solids. 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.

11.1.7
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
As wet
season has come, 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 working areas near Ma
Wat Channel and Ping Yuen River. Moreover, 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.
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.
