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.
There was one Action Level exceedances of SS on
impact water quality monitoring at station IS(Mf)9 during mid-flood tide recorded on 14 December 2016. After investigation, there was concluded that the exceedance was 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 IS(Mf)9 from 01 December 2016 to the water quality monitoring period at 07:51 on
14 December 2016 which was unlikely to generate suspended solids in the marine
water. Therefore, it is unlikely that the SS exceedance recorded at IS(Mf)9 during mid-flood
tide on 14 December 2016 was contributed by the works under Contract No.
HY/2013/02. There was no
Action and Limit Level
exceedance recorded on other monitoring

Monitoring Result
4.3.1
The monitoring
results for the monitoring stations showed in Table 4.1 are reported in
the monthly EM&A Report prepared for Contract No. HY/2010/02. There was one
Action
Level exceedance of Suspended Solids on impact water quality monitoring at
station IS(Mf)9 during mid-flood tide recorded on 14 December 2016.
4.3.2
Exceedance
was not due to operation of the works under Contract No. HY/2013/02 because 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 IS(Mf)9 from 01 December 2016 to the water quality
monitoring period at 07:51 on 14 December 2016 which was unlikely to generate
suspended solids in the marine water. Therefore, it is unlikely that the SS
exceedance recorded at IS(Mf)9 during mid-flood tide on 14 December 2016
was contributed by the works under Contract No. HY/2013/02. The water quality
mitigation measures as mentioned in EM&A Manual and EP was fully
implemented in this Contract which including maintenance of the silt curtain on
a daily basis etc. Hence, the exceedance was considered as non-Project related.
4.3.3
After
investigation, there was concluded that the exceedance was not relevant to this
Contract due to the above mentioned reasons. The Investigation Report
(including the causes of exceedance, action taken and recommendation for
mitigation) for Action or Limit Level Non-compliance was prepared by the ET of
Contract No. HY/2010/02 and detailed in the monthly EM&A Report prepared
for Contract No. HY/2010/02. There was no Action and Limit Level exceedance
recorded on other monitoring date at the monitoring
stations showed in Table 4.1 by the Environmental Team of Contract No.
HY/2010/02 during the reporting period.
4.3.4
Although the exceedance was not relevant to this
Contract, the Contractor was reminded to ensure that the maintenance of
perimeter silt curtains with respect to the work boundary of this Contract
carried out by the Contractor of Contract
No. HY/2010/02 are maintained properly.
