Breaches of Action and Limit
Levels
Summary
of Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at
AMS6 shall be referred to the monthly EM&A report prepared by Contract No.
HY/2011/03.
There was no Action and Limit Level exceedance
of 1-hr TSP level and 24-hr TSP level
recorded at station AMS7 by the Environmental Team of Contract No. HY/2010/02 during the reporting period.
There was no Action and Limit Level exceedance
for noise recorded at
station NMS2 and station NMS3B by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
For water quality monitoring,there
were twoaction level
exceedances of suspended
solid on impact water quality monitoring at
station SR3 during mid-ebb tide and IS7
during mid-flood tide recorded on 12 July 2017 and 14 July 2017 respectively. After investigation, there was concluded that the exceedances were not relevant to this Contract since there was no marine works or barge of this Contract worked at HKBCF
reclamation site near the sea area or area near the monitoring station SR3 and IS7 from 12 July 2017 to 14July
2017which was unlikely
to generate suspended solid to cause the suspended solid exceedances recorded at the monitoring station SR3 during mid-ebb tide and IS7 during mid-flood
tide recorded on 12 July 2017 and 14
July 2017 respectively.The Investigation Reports No. 017 and 018(including the causes of exceedance, action taken and recommendation for
mitigation) for Action or Limit Level Non-compliance were provided in AppendixJ.There was no Action and Limit Level exceedance recorded on other monitoring date at the

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 hasbeen
assigned to coordinate and arrange for disposal of extracted marine sediment
from Contract Nos. HY/2013/02, HY/2013/03 and HY/2013/04.

For
the dumping arrangement, the barge for disposal 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.
3.6.4.3
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.
