After investigation, there
was concluded that the exceedances were not relevant to this Contract since there was only one marine based activity which is demolition of temporary loading and
unloading pointof this Contract
worked at HKBCF reclamation site near the sea area or area near the monitoring stations.The demolition of temporary loading and unloading point was started from
18 July 2017. The major marine based activity was the removal of marine piling
of temporary loading and unloading point.
All marine based activities were carried out within the silt curtain and no
defect of silt curtain was recorded by Contract No. HY/2010/02 from 18 July 2017 to 31August 2017. Besides, there was also no DO, turbidity and SS
exceedance recorded during 18 July 2017 to 31 August 2017. Therefore, the exceedance was not caused by demolition of temporary loading and
unloading point.The Investigation Reports No. 019, 020,
021 and 022(including
the causes of exceedance, action taken and recommendation for mitigation) for
Action or Limit Level Non-compliance were provided in Appendix J. As confirmed by SRE, removal of temporary loading and
unloading point by Contract No. HY/2013/02, which involved marine work, was
completed on 10 September and the area was handed back to Reclamation
Contractor on 11 September 2017 for subsequent seawall construction. No
marine based works for demolition of loading and unloading point was conducted
so that no investigation report was provided for all exceedances recorded after
11 September 2017. There was no Action and Limit Level exceedance
recorded on other monitoring date at the monitoring stations showed at Table
4.1 by the Environmental Team of Contract No. HY/2013/01 during the reporting
period.

4.3.2
After investigation, there was concluded that the
exceedances were not relevant to this Contract since there was only one marine
based activity which is demolition of temporary loading and unloading pointof this Contract worked at HKBCF reclamation
site near the sea area or area near the monitoring stationsThe demolition of temporary loading and unloading point
was started from 18 July 2017. The major marine based activity was the removal
of marine piling of temporary loading and unloading point. All marine based activities were carried
out within the silt curtain and no defect of silt curtain was recorded by Contract
No. HY/2010/02 from 18 July
2017 to 31August 2017. Besides, there was also no DO, turbidity and SS exceedance recorded during 18 July 2017 to 31 August
2017. Therefore, the exceedance was not caused by demolition
of temporary loading and unloading point.The Investigation Reports No. 019, 020, 021 and 022(including the causes of exceedance, action taken
and recommendation for mitigation) for Action or Limit Level Non-compliance
were provided in Appendix J. As confirmed by
SRE, removal of temporary loading and unloading point by Contract No.
HY/2013/02, which involved marine work, was completed on 10 September and the
area was handed back to Reclamation Contractor on 11 September 2017 for
subsequent seawall construction. No marine based works for demolition of
loading and unloading point was conducted so thatno investigation report was
provided for all exceedances recorded after 11 September 2017.There was
no Action and Limit Level exceedance recorded on other monitoring date at the
monitoring stations showed at Table 4.1 by the Environmental Team of
Contract No. HY/2013/01 during the
reporting period.

Disposal of Marine
Sediment
6.2.3.1
For the marine sediment disposal, after the
acceptance of the review of the approved Sediment Quality Report (SQR) for this
Project under EPD letter dated 19 August 2015, an approval to dispose the
marine sediment extracted from bored piling for this Project was then approved
under memo from Secretary, Marine Fill Committee of CEDD dated 20 August 2015
for the disposal of marine sediment extracted from bored piling works. The
disposal sites allocated to this Project are the Mud Pit CMP2 of the Confined
Marine Sediment Disposal Facility to the South of The Brothers (or at the East
of Sha Chau). As advised by CEDD in the memo dated 19 February 2016, from 00:00
on 22 March 2016 onward, the disposal space at CMP2 of the South of The
Brothers is closed and all disposal of contaminated sediment is to be carried
out at CMP Vd to the East of Sha Chau (ESC). As a practical means, the disposal
operation is managed by one contractor who is also responsible for applying
dumping permit and its subsequent extension applications from EPD. Contract No.
HY/2013/03 has been assigned to coordinate and arrange for disposal of
extracted marine sediment from Contract No. HY/2013/02, HY/2013/03 and

of marine sediment will moor at the temporary loading and unloading at the east
shore of the HKBCF Island, which has been being used by contractor Contract No.
HY/2010/02 for reclamation activities. In terms of safety consideration and to
avoid mixing of sediment between contracts, each dumping date will be allocated
to one Contract. The quantity of marine sediment disposed on each date is from
one Contract.
6.2.3.3 During dumping,
HY/2013/02 is responsible for transporting the marine sediment from his site
area to the barge by Land transportation. The estimated quantity of marine
sediment in each truck is confirmed by Resident Site
Staff of each Contract. The trip tickets for transportation and disposal of
marine sediment are collected and checked. Contract No. HY/2013/03 as the
dumping permit holder is responsible for reporting to EPD the quantity
disposed of as the condition stipulated in the dumping permit.
6.2.4 There was no marine sediment
extracted from bored piling in this Contract disposed to allocated dumping site
via Contract No. HY/2013/03 in this reporting period. As confirmed by RSS that the disposal ofexcavated marine sediments has been completed
with the last batch disposal on 30 August 2017. The quantity disposed up to end of September 2017 was 20664 m3.The Monthly Summary of Marine sediment disposed to
